             For the Annual Meeting of Stockholders on May 11, 2007

                                  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., which we refer to
as the Company or FSP, for use at the Annual Meeting of Stockholders to be held
on May 11, 2007, 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 notice of meeting, this proxy statement, the enclosed proxy card and our
Annual Report on Form 10-K for the year ended December 31, 2006 are first being
mailed or given to stockholders on or about April 2, 2007. We will furnish, upon
written request of any stockholder and the payment of an appropriate processing
fee, copies of any exhibits that are missing from our Annual Report on Form
10-K. Please address all such requests to Franklin Street Properties Corp., 401
Edgewater Place, Suite 200, Wakefield, Massachusetts 01880, Attn: Barbara J.
Fournier, Secretary.

Quorum Requirement

At the close of business on March 16, 2007, 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 70,766,305
shares of common stock of the Company, which we refer to as Common Stock,
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.


                                        1


Votes Required

The affirmative vote of the holders of a plurality of all 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.

Beneficial Ownership of Voting Stock

The following table sets forth the beneficial ownership of our Common Stock as
of March 16, 2007 by each director or nominee for director, by each of the
executive officers named in the Summary Compensation Table set forth below, or
the Named Executive Officers, and by all current directors and executive
officers as a group. To our knowledge, no person or group, other than as set
forth below, beneficially owns more than five percent of our Common Stock.

Board and Committee Meetings

Our Board of Directors held six meetings during 2006 in person or via

the directors attended all of the (i) meetings of the Board of Directors and
(ii) meetings held by all committees of the Board on which he or she served, in

policy that all directors are expected to attend the annual meeting of
stockholders. All directors attended the 2006 annual meeting of stockholders in

Stock Exchange; the application was approved in early 2005, and our Common Stock
began trading on the American Stock Exchange on June 2, 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 in carrying out the
responsibilities of a director. Our Board of Directors has determined that none
of Messrs. Burke, McGillicuddy, or Silverstein or Ms. Murray has a material
relationship with the Company that would interfere with the exercise of
independent judgment in carrying out the responsibilities of a director and that
each of these directors is "independent" as defined in Section 121A of the
American Stock Exchange Company Guide.

Audit Committee

We have a standing audit committee of the Board of Directors. The audit
committee is responsible for, among other things, reviewing financial reports,
accounting procedures and the scope and results of the annual audit of our
financial statements, overseeing the qualifications and independence of our
independent auditors and reviewing and approving our policies and procedures for

                                       6


members of the audit committee are Mr. Burke, who is the Chair of the committee,
Mr. McGillicuddy, Mr. Silverstein and Ms. Murray. The audit committee acts under
a written charter that is available on our website at
www.franklinstreetproperties.com.

Our Board of Directors has determined that all of the members of the audit
committee are "independent" as defined in Section 121A of the American Stock
Exchange Company Guide. The Board of Directors has also determined that Mr.
Burke, the Chair of the audit committee, is qualified as an "audit committee
financial expert" as the term is defined in Item 407(d)(5) of Regulation S-K,
promulgated by the Securities and Exchange Commission. In addition, the audit
committee satisfies the additional independence requirements set forth in
Section 121B of the American Stock Exchange Company Guide. The members of the
audit committee held six meetings in 2006 in person or via teleconference.

Compensation Committee

We have a standing compensation committee of the Board of Directors. The

current members of the compensation committee are Ms. Murray, who replaced Mr.
McGillicuddy as the Chair of the committee in October 2006, and Messrs. Burke,
McGillicuddy and Silverstein. The Board of Directors has determined that all of
the members of the compensation committee are "independent" as defined in
Section 121A of the American Stock Exchange Company Guide. The members of the
compensation committee met one time in 2006 in person or via teleconference and
acted on one occasion by unanimous written consent. The compensation committee
acts under a written charter that is available on our website at
www.franklinstreetproperties.com.

The compensation committee is authorized to form and delegate its authority to
one or more subcommittees as it deems appropriate from time to time under the
circumstances. As of March 23, 2007, the compensation committee had not formed
any subcommittees. In addition, the compensation committee has the authority to
retain and terminate any compensation consultant to be used to assist in the
evaluation of executive officer compensation. The compensation committee has the
authority to approve the consultant's fees and other retention terms and pay the
compensation without further action by the Board. As of March 23, 2007, the
compensation committee had not retained any compensation consultants. The
compensation committee also has authority to commission compensation surveys or
studies as the need arises.

The compensation committee annually reviews and approves corporate goals and
objectives relevant to the compensation of our Chief Executive Officer,
evaluates the Chief Executive Officer's performance in light of those goals and
objectives and either determines and approves or recommends to the Board of
Directors for approval, the Chief Executive Officer's compensation based on this
evaluation. The Chief Executive Officer is not permitted to be present during
any such deliberations or voting. In addition, based upon the recommendations of
the Chief Executive Officer, the compensation committee annually oversees the
evaluation of our other executive officers and annually reviews and approves or
makes recommendations to the Board of Directors regarding their compensation.
The compensation committee is also responsible for director compensation,
periodically reviewing and making recommendations to


                                       7


the Board of Directors with respect to incentive compensation and equity-based
plans and the administration of any such incentive compensation and equity-based
plans.

Director Candidates

We do not have a standing nominating committee. Instead, director nominations
are recommended for the Board's selection by a majority of our independent
directors in accordance with Section 804(a) of the American Stock Exchange
Company Guide. Once recommended, each member of the Board participates in the
consideration of director nominees. The Board of Directors has determined that
it is appropriate for us 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 or, when appropriate, the independent
directors only. Mr. Carter, Ms. Fournier and Ms. Notopoulos would not be deemed
to be "independent" under the listing standards of the American Stock Exchange.

The process followed by the Board 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 nominate any particular candidate who has been
recommended by a majority of our independent directors, the Board of Directors
applies criteria including the candidate's integrity, business acumen, knowledge
of our 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 weight 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.

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 our principal
office, Attn: Barbara J. Fournier, Secretary. Assuming that appropriate
biographical and background material has been provided on a timely basis, the
Board 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 our proxy card for the next annual
meeting.

Stockholders also have the right under our 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 our proxy card for the next annual
meeting.


                                       8


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.

                             EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Overview

      As an investment firm that specializes in real estate, it is critical that
      we be able to attract, motivate and retain highly talented individuals at
      all levels of the organization. We believe that compensation levels should
      be adequately competitive to attract and retain experienced and capable
      leaders and motivate those individuals to achieve exceptional results and
      reward them for being instrumental in reaching our strategic goals. At the
      same time, we believe in simplicity and maintaining compensation at
      responsible levels. For 2006, the compensation of executives consisted of
      the same five components as were provided to all of our employees: (1)
      base salary (or brokerage commissions in the case of employees who are
      investment executives as further described below); (2) the potential for a
      cash bonus (except in the case of investment executives and their sales
      assistants and administrative staff); (3) the potential for an award of
      common stock under our stock incentive plan; (4) matching for individual
      401(k) plan contributions; and (5) the potential for a payment or payments
      under our change-in-control program. We do not offer stock options,
      restricted stock awards, deferred compensation, non-equity incentive plan
      compensation or perquisites. In addition, none of our employees have
      employment agreements and we do not require any of our employees to own
      our common stock.

      Our executive officers fall into two categories. The first category
      comprises executive officers who make up the corporate management team.
      Our corporate management team consists of our chief executive officer, our
      chief operating officer, our chief financial officer and the president of
      FSP Property Management LLC. The second category comprises executive
      officers who are investment executives. Our investment executives are
      engaged in the private placement of equity in single-purpose entities,
      which we refer to as Sponsored REITs, that we organize to own real estate.
      The Sponsored REITs are operated in a manner intended to qualify as real
      estate investment trusts. The compensation of our investment executives
      consists primarily of brokerage commissions.

The objectives of our compensation programs

      o     Our compensation committee bases its executive compensation programs
            on the same core objectives that guide us in establishing all of our
            compensation programs:

      o     Compensation should promote the achievement of our business goals
            and maximize corporate performance and shareholder returns.

      o     Compensation should be based on the principles of competitive and
            fair compensation and sustained performance.

      o     Compensation should be based on the level of job responsibility,
            individual performance and FSP performance. As employees advance to
            higher levels within the organization, an increasing proportion of
            their compensation should be linked to FSP's performance and
            maintaining shareholder value.


                                       10


      o     Compensation should reflect the value of the job in the marketplace.
            Compensation should be competitive with other employers that compete
            with us for talent so that we continue to be able to attract and
            retain highly talented employees.

      o     Compensation should reward performance. Our compensation programs
            should deliver competitive compensation when individual and FSP
            performance meet and/or exceed expectations. Similarly, our
            compensation programs should deliver less compensation, including
            the possibility of no cash bonus, in the event that individual
            and/or FSP performance fall short of expectations.

      o     Compensation should be equitable. We strive to achieve equitable
            distributions both for compensation of individual officers and
            between officers and other employees throughout the organization.

      o     Compensation and benefit programs should be designed to attract,
            motivate and retain highly talented employees who are interested in
            building a career with us.

What the compensation programs are designed to reward and how FSP determines the
amount (and, where applicable, the formula) for each element to pay

      With respect to executive officers who make up the corporate management
      team, decisions regarding compensation are based on actual corporate and
      individual performance against targeted company and individual performance
      and various subjective performance criteria.

      Our compensation committee has established a number of processes to assist
      it in ensuring that our executive compensation program achieves its
      objectives. Among those are:

      o     Consideration of various measures of corporate performance,
            including reviewing the extent to which strategic and business plan
            goals are met, levels of property acquisitions, performance of
            properties in FSP's portfolio, gains or losses on property
            dispositions, levels of equity sales and earnings, adjusted funds
            from operations, or AFFO, dividends and maintaining shareholder
            value. Our compensation committee does not apply a formula or assign
            these performance measures relative weights. Instead, it makes a
            subjective determination after considering such measures
            collectively.

      o     Consideration of individual performance. The members of the
            compensation committee meet with the chief executive officer
            annually at the beginning of the year to agree upon performance
            objectives (both individual and company objectives) for the year. At
            the end of the year, the members of the compensation committee meet
            to conduct a performance review of the chief executive officer based
            on his achievement of the agreed-upon objectives, contribution to
            company performance, the degree to which teamwork and company values
            are fostered and other leadership accomplishments. This evaluation
            is shared with the chief executive officer and is considered by the
            compensation committee in establishing the chief executive officer's
            compensation. With respect to the other named executive officers,
            the members of the compensation


                                       11


            committee receive a performance assessment and compensation
            recommendation from the chief executive officer. In establishing the
            compensation for each of the other named executive officers, the
            compensation committee considers the performance assessment and
            compensation recommendation from the chief executive officer and
            also exercises its own judgment based on its assessment of whether
            the other named executive officers achieved their agreed-upon
            objectives, their contributions to company performance, the degree
            to which teamwork and company values were fostered and other
            leadership accomplishments.

      o     Comparison of our executive compensation programs as a whole and
            also a comparison of individual executive compensation with the
            compensation practices of other companies in the real estate
            industry. Historically, the compensation committee has used the
            NAREIT Annual Compensation Survey for comparison purposes. To ensure
            that total compensation is competitive, the compensation committee
            uses the results of the comparison to establish compensation
            guidelines.

      As mentioned above, the compensation of our executive officers who are
      investment executives consists primarily of brokerage commissions. 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 the
      individual investment executive. An investment executive's ability to earn
      commissions is limited only by the amount of equity available to be sold
      and his or her individual ability to sell it. As a result, the
      compensation committee does not set the level of compensation for
      executive officers who are investment executives. The compensation
      committee does determine the percentage of payout that is paid to the
      investment executives. In order to ensure that the percentage of payout
      that is paid to the investment executives is competitive, the compensation
      committee periodically compares its commission practices with those of
      other companies in the investment industry and sets its percentage of
      payout based on this review. The compensation committee believes that the
      percentage of payout is competitive within the investment industry.

Each element of compensation and why FSP chooses to pay each element

(a)   Base Salary or Brokerage Commissions

      Executive officers who make up the corporate management team are paid a
      base salary. We believe that a competitive base salary provides an
      important guaranteed element to compensation. We also believe that the
      payment of a competitive base salary is consistent with the compensation
      practices of other comparable companies.

      Executive officers who are investment executives are not paid a base
      salary. Instead, they are paid brokerage commissions. 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. An investment executive's ability to earn
      commissions is limited only by the amount of equity available to be sold
      and his or her individual ability to sell it. We believe that this
      commission structure provides a necessary monetary incentive that
      encourages


                                       12


      increased sales. We also believe that the payment of brokerage commissions
      is consistent with the compensation practices of other comparable
      companies.

(b)   Cash Bonus

      Executive officers who make up the corporate management team are eligible
      for a cash bonus based on actual company and individual performance
      against targeted company and individual performance and various subjective
      performance criteria. The payment of a cash bonus is purely discretionary
      based upon overall performance and in some years there could be no cash
      bonus payments. We believe that the opportunity to earn a competitive cash
      bonus provides a monetary incentive that encourages both company and
      individual performance. We also believe that the payment of a competitive
      cash bonus is consistent with the compensation practices of other
      comparable companies.

      Executive officers who are investment executives, together with their
      sales assistants and administrative staff, are not eligible for a cash
      bonus.

(c)   Award of Common Stock

      Executive officers are eligible for awards of common stock under our 2002
      stock incentive plan. On May 20, 2002, our stockholders approved the 2002
      stock incentive plan, which had been previously adopted by our board on
      February 8, 2002. The 2002 stock incentive plan permits the board to award
      up to 2,000,000 shares of our common stock to eligible participants. Prior
      to our listing on the American Stock Exchange in June 2005, our employees
      were not able to purchase our common stock. We determined that it was
      necessary and appropriate to be able to compensate our employees with
      stock as a means of attracting, retaining and motivating key personnel and
      to align the interests of management and all personnel with those of our
      shareholders. All of our employees, officers and directors are eligible to
      participate in the plan. As of March 23, 2007, 1,944,428 shares of our
      common stock were available under the plan. There have been no awards of
      common stock under the 2002 stock incentive plan since we listed our
      common stock on the American Stock Exchange in June 2005, as employees are
      now able to purchase common stock in the open market. In the future,
      however, we may award stock under the plan in order to attract, retain, or
      motivate our executives.

(d)   401(k) Matching

      Executive officers are eligible to participate in our 401(k) plan. We
      offer all employees a 401(k) plan that, in 2006, allowed for salary
      deferrals of up to $15,000 per year (indexed for inflation). We matched up
      to 3% of an employee's compensation (up to a cap of $200,000) for plan
      year 2006 and will match up to 3% of employee compensation (up to a cap of
      $225,000) for plan year 2007. Employees make their 401(k) contributions
      through payroll deductions with pretax dollars. All employees are eligible
      to participate in the plan after one year of service and completion of
      1,000 hours of service. The plan allows for quarterly enrollment. The
      employee's elective deferrals are immediately vested upon contribution to
      the 401(k) plan, and the employee has sole decision making authority as to
      the investment of funds. We believe that our 401(k) plan provides a
      vehicle for our employees to plan for their long-term security and that
      such a


                                       13


      plan ultimately leads to improved job performance. We also believe that
      our 401(k) plan is consistent with the compensation practices of other
      comparable companies.

(e)   Change-in-Control Program

      Except in the case of a change-in-control of FSP, we are not obligated to
      pay severance or other enhanced benefits to named executive officers upon
      termination of their employment.

      In February 2006, we adopted a change-in-control program for all our
      employees, including our executive officers. The program was adopted in
      response to recent merger and consolidation activity within the real
      estate/real estate investment trust industry and is intended to preserve
      employee morale and productivity and encourage retention in the event of
      an actual or rumored change-in-control of FSP. The program is also
      intended to align employee and shareholder interests by enabling employees
      to consider corporate transactions that are in the best interests of the
      shareholders and other constituents of FSP without undue concern over
      whether the transaction or transactions may jeopardize the employee's own
      employment.

      Although there are some differences in payment amounts depending on the
      employee's job level, the basic elements of the program are comparable for
      all employees:

      o     The program consists of two components: a fixed payment pursuant to
            a retention agreement between the employee and FSP and the potential
            for an additional discretionary payment pursuant to a discretionary
            plan.

      o     The triggering event for both components is a change-in-control of
            FSP. A change-in-control of FSP as defined in the plan generally
            refers to a change in ownership or effective control of FSP or a
            change in ownership of a substantial portion of the assets of FSP.

      o     Under the retention agreement component of the program, employees
            would receive a payment as soon as practicable following the closing
            of the change-in-control, but in no event more than thirty days
            following the closing of the change-in-control. Executive officers
            who make up the corporate management team would receive payments
            equal to three years of their base salaries plus a bonus opportunity
            payment equal to three years of their base salaries. Executive
            officers who are investment executives would receive payments equal
            to the average of the lump sum payments made to the chief financial
            officer and the chief operating officer. For purposes of the
            retention agreement component of the program, base salary refers to
            the base salary of the employee in effect at the time of the closing
            of the change-in-control.

      o     Under the discretionary plan component of the program, immediately
            prior to the closing of the change-in-control, the board may (but is
            not obligated to) establish a discretionary pool of funds equal to
            1% of the market capitalization of FSP immediately prior to the
            closing of the change-in-control less the total amount of payments
            to all employees under the retention agreement component of the
            program. The board would have complete discretion to award all, a
            portion or none of the discretionary plan pool of funds to any
            employees of FSP, including the executive officers.


                                       14


      Prior to adopting our change-in-control program, management reviewed plans
      similar to our retention agreement component offered by approximately ten
      other publicly-traded real estate investment trusts and concluded that our
      triggering event was generally consistent with the peer group. Management
      did not review any plans that were comparable to our discretionary plan
      but concluded that, on balance, the total potential payout amounts under
      our change-in-control program are generally consistent with the range
      offered by the peer group.

      Our chief executive officer has voluntarily elected not to participate in
      the retention agreement component of our change-in-control program.

How each compensation element and FSP's decisions regarding that element fit
into FSP's overall compensation objectives and affect decisions regarding other
elements

Overview

      From a historical perspective, we achieved very good financial results for
      2006. The three components upon which our financial metrics are based:
      rental income from operations; gains or losses on sales of properties; and
      fee income from real estate investment banking activities, performed well.
      Based upon its review of the compensation practices of other comparable
      companies, the compensation committee believes that total compensation for
      the executive officers is within the range of total compensation paid to
      executive officers with comparable qualifications, experience and
      responsibilities in the same or similar businesses and of comparable size
      and success.

(a)   Base Salary or Brokerage Commissions

      In establishing base salaries for 2006, the members of the compensation
      committee applied the principles described above under "What the
      compensation programs are designed to reward and how FSP determines the
      amount (and, where applicable, the formula) for each element to pay."
      Based upon the recommendation of the chief executive officer, the
      compensation committee approved base salary increases for each of the
      other executive officers who make up the corporate management team. The
      base salary levels for these positions had remained constant for the prior
      three years (except for the chief financial officer whose last base salary
      increase occurred in 2005 after being promoted to the position of chief
      financial officer). The base salary increases were effective on February
      1, 2006. With respect to the chief executive officer, the compensation
      committee recommended to the board that Mr. Carter's base salary be
      increased to $375,000. The full board (with Mr. Carter abstaining)
      unanimously approved the compensation committee's recommendation. However,
      Mr. Carter declined to accept the base salary increase.

      Our base salary amounts are generally lower than industry standard levels.
      No recommendation was made for base salary increases for 2007. Rather,
      compensation of these positions will be weighted proportionately greater
      towards year-end bonus amounts based upon corporate and individual
      performance.

      No recommendation was made to adjust our brokerage commission structure.


                                       15


(b)   Cash Bonus

      In awarding cash bonuses for 2006, the members of the compensation
      committee applied the principles described above under "What the
      compensation programs are designed to reward and how FSP determines the
      amount (and, where applicable, the formula) for each element to pay."
      Based upon the recommendation of the chief executive officer, on February
      2, 2007, the compensation committee approved cash bonuses for each of the
      other executive officers who make up the corporate management team. In
      making his recommendation, Mr. Carter noted, and the compensation
      committee agreed, that each officer's area of responsibility and
      accountability (i.e., business unit) contributed to our achieving our
      business goals during 2006, as a result of each person's leadership and
      direction. It was further noted that each of these individuals was
      considered to be integral to the daily operations of FSP and of great
      value to FSP and firmly committed to doing what is in the best interests
      of our shareholders. The cash bonus amounts are higher than past years.
      The compensation committee believes that the cash bonus amounts properly
      reflect FSP's overall positive performance for 2006 and the belief that
      the results were a direct consequence of the dedication and hard work of
      these individuals and their staffs.

      The compensation committee also reviewed and evaluated the performance of
      Mr. Carter during 2006 by applying the principles described above under
      "What the compensation programs are designed to reward and how FSP
      determines the amount (and, where applicable, the formula) for each
      element to pay." As previously stated, FSP achieved very good financial
      results for 2006. The three components upon which our financial metrics
      are based: rental income from operations; gains or losses on sales of
      properties; and fee income from real estate investment banking activities,
      performed well under the leadership, focus and discipline of Mr. Carter.
      Based upon numerous performance measurements, the compensation committee
      felt that FSP had a positive year. Mr. Carter's overall performance was
      considered excellent by the compensation committee. However, at the
      request of Mr. Carter, the compensation committee did not consider making
      any recommendation to the board for a cash bonus for 2006 performance.
      Although FSP's results during 2006 were outstanding, the price of our
      common stock did not increase measurably over the course of the year. The
      opening price per share on January 3, 2006 was $20.90 and the closing
      price per share on December 29, 2006 was $21.05. Mr. Carter believes that
      the chief executive officer has the ultimate responsibility for the stock
      price and that, as part of that responsibility, the chief executive
      officer's compensation should reflect the stock's relative performance in
      the marketplace. The compensation committee determined that, based upon
      the intrinsic financial performance of FSP and based upon Mr. Carter's
      individual performance, Mr. Carter deserved a bonus. However, the
      compensation committee decided to honor Mr. Carter's request that he not
      be considered for a cash bonus.

(c)   Award of Common Stock

      Because FSP determined that it was able to adequately compensate the
      executive officers who make up the corporate management team with salary
      and cash bonuses in 2006, no proposal was made for the award of common
      stock. In other years, the award of common stock could be utilized as a
      compensation option.


                                       16


(d)   401(k) Matching

      Because our 401(k) was adopted in 2006, there were no proposals made to
      further modify the plan.

(e)   Change-in-Control Program

      Because our change-in-control program was adopted in 2006, there were no
      proposals made to further modify the program.


                                       17

Potential Payments Upon Termination or Change in Control

In February 2006, we adopted a change-in-control program for all our employees,
including our executive officers. We adopted the program in response to recent
merger and consolidation activity within the real estate/real estate investment
trust industry, to preserve employee morale and productivity and to encourage
retention in the event of an actual or rumored change-in-control of the company.
The program is also intended to align employee and shareholder interests by
enabling employees to consider corporate transactions that are in the best
interests of the shareholders and other constituents of the company without
undue concern over whether the transaction or transactions may jeopardize the
employee's own employment. For an overview of our change-in-control program,
please refer to the discussion included under the heading "Compensation
Discussion and Analysis - Each element of compensation and why the company
chooses to pay each element - (e) Change-in-Control Program."

Assuming that the closing of a change-in-control occurred on December 29, 2006,
the last business day of our fiscal year, our named executive officers would be
entitled to payment of the following amounts under the retention agreement
component of our change-in-control program:



-------------------------------------------------------------------------------------------------------
Name and Principal Position                              Payment due under the Retention Agreement (1)

-------------------------------------------------------------------------------------------------------


NOTES

(1)   With respect to executive officers who make up the corporate management
      team, these are lump-sum payments equal to three years of their base
      salaries plus a bonus opportunity payment equal to three years of their
      base salaries. With respect to executive officers who are investment
      executives, these are lump-sum payments equal to the average of the lump
      sum payments made to the chief financial officer and the chief operating
      officer. In both cases, the payment amounts are subject to a possible
      reduction, if any, after the tax consequences are determined.

(2)   George J. Carter has voluntarily elected not to participate in the
      retention agreement component of our change-in-control program.

Under the discretionary plan component of our change-in-control program, our
board of directors has the right, but not the obligation, to establish a
discretionary pool of funds equal to 1% of our market capitalization immediately
prior to the closing of the change-in-control. On December 29, 2006, there were
70,766,305 shares of our common stock outstanding, and the closing price


                                       20


per share of our common stock on the American Stock Exchange was $21.05.
Accordingly, on December 29, 2006, our market capitalization was $1,489,630,720,
and 1% of our market capitalization equaled $14,896,307. This $14,896,307 amount
would then be reduced by the total amount of payments due and payable to all of
our employees (including our named executive officers) under the retention
agreement component of our change-in-control program. Our board of directors
would then have complete discretion to award all, a portion or none of the
remaining balance to any of our employees, including our named executive
officers. As is the case with the retention agreement component of our
change-in-control program, any payments under the discretionary plan component
are subject to a possible reduction, if any, after the tax consequences are
determined.

Compensation Committee Interlocks and Insider Participation

The compensation committee consists of Messrs. McGillicuddy, Silverstein and
Burke and Ms. Murray. 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.

Compensation Committee Report

The compensation committee has reviewed and discussed with management the
Compensation Discussion and Analysis included in this proxy statement. Based on
this review and these discussions, we recommended to the Board of Directors that
the Compensation Discussion and Analysis be included in this proxy statement and
incorporated by reference into the Company's Annual Report on Form 10-K for the
fiscal year ended December 31, 2006.

By the compensation committee of the Board of Directors of Franklin Street

             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Based solely on its review of copies of reports filed by the directors and
executive officers of the Company pursuant to Section 16(a) of the Exchange Act
or written representations from certain persons required to file reports under
Section 16(a) of the Exchange Act, the Company believes that during 2006 all
filings required to be made by its reporting persons were timely made in
accordance with the requirements of the Exchange Act.

                        TRANSACTIONS WITH RELATED PERSONS

Related Person Transaction Policy

On February 2, 2007, our Board adopted written policies and procedures for the
review of any transaction, arrangement or relationship in which the Company is a
participant, the amount involved exceeds $120,000, and one of our executive
officers, directors, director nominees or 5% stockholders (or their immediate
family members), each of whom we refer to as a related person, has a direct or
indirect material interest.

If a related person proposes to enter into such a transaction, arrangement or
relationship, which we refer to as a related person transaction, the related
person must report the proposed related person transaction to our chief
operating officer or in-house counsel.

The policy calls for the proposed related person transaction to be reviewed and,
if deemed appropriate, approved by the audit committee of our Board. Whenever
practicable, the reporting, review and approval will occur prior to entry into
the transaction. If advance review and approval is not practicable, the audit
committee will review, and, in its discretion, may ratify the related person
transaction. The policy also permits the chairman of the audit committee to
review and, if deemed appropriate, approve proposed related person transactions
that arise between committee meetings, subject to ratification by the committee
at its next meeting. Any related person transactions that are ongoing in nature
will be reviewed annually.

A related person transaction reviewed under the policy will be considered
approved or ratified if it is authorized by the audit committee after full
disclosure of the related person's interest in the transaction. As appropriate
for the circumstances, the committee will review and consider:

      o     the related person's interest in the related person transaction;

      o     the approximate dollar value of the amount involved in the related
            person transaction;

      o     the approximate dollar value of the amount of the related person's
            interest in the transaction without regard to the amount of any
            profit or loss;

      o     whether the transaction was undertaken in the ordinary course of our
            business;

      o     whether the terms of the transaction are no less favorable to us
            than terms that could have been reached with an unrelated third
            party;

      o     the purpose of, and the potential benefits to us of, the
            transaction; and

      o     any other information regarding the related person transaction or
            the related person in the context of the proposed transaction that
            would be material to investors in light of the circumstances of the
            particular transaction.


                                       23


The audit committee may approve or ratify the transaction only if the committee
determines that, under all of the circumstances, the transaction is in, or is
not inconsistent with, our best interests. The audit committee may impose any
conditions on the related person transaction that it deems appropriate.

In addition to the transactions that are excluded by the instructions to the
SEC's related person transaction disclosure rule, the Board has determined that
the following transactions do not create a material direct or indirect interest
on behalf of related persons and, therefore, are not related person transactions
for purposes of this policy:

      o     Interests arising only from the related person's position and
            ownership level as a director of another corporation or organization
            that is a party to the transaction;

      o     Interests arising only from the position and ownership level from
            direct or indirect ownership by the related person and all other
            related persons in the aggregate of less than a 10% equity interest
            (other than a general partnership interest) in another entity which
            is a party to the transaction;

      o     Interests arising solely from the ownership of a class of our equity
            securities if all holders of that class of equity securities receive
            the same benefit on a pro rata basis;

      o     A transaction that involves compensation to an executive officer if
            the compensation has been approved, or recommended to the Board for
            approval, by the compensation committee of the Board or a group of
            independent directors of the Company performing a similar function;

      o     A transaction that involves compensation to a director for services
            as a director of the Company if such compensation will be reported
            pursuant to Item 402(k) of Regulation S-K;

      o     A transaction that is specifically contemplated by provisions of the
            Company's charter or bylaws;

      o     Interests arising solely from indebtedness of a significant
            shareholder or an immediate family member of a significant
            shareholder to us;

      o     A transaction where the rates or charges involved in the transaction
            are determined by competitive bids;

      o     A transaction that involves the rendering of services as a common or
            contract carrier or public utility at rates or charges fixed in
            conformity with law or governmental authority;

      o     A transaction that involves services as a bank depositary of funds,
            transfer agent, registrar, trustee under a trust indenture, or
            similar services;

      o     Interests arising as a result of a related person serving as an
            officer and/or director of another company or a Sponsored REIT at
            our request; or


                                       24


      o     A transaction that involves the payment by a Sponsored REIT to the
            Company (or any wholly-owned subsidiary thereof) of customary fees
            including, without limitation, acquisition, syndication, sales
            commissions, interim financing and asset management fees.

The policy provides that transactions involving compensation of executive
officers shall be reviewed and approved by the compensation committee in the
manner specified in its charter.

Transactions with Related Persons

Messrs. Carter, MacPhee and Gribbell and Mses. Fournier and Notopoulos, each of
whom is an executive officer of the Company, serve, at our request, as executive
officers and directors of each of the Sponsored REITs. None of such persons
receives any remuneration from the Sponsored REITs for such service. We are
involved in several transactions with the Sponsored REITs.

FSP Investments LLC, 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 $1,422,000 for the year ended December 31, 2006. As of March 14,
2007, the fees from Sponsored REITs amounted to approximately $87,000 during
2007. Sales commissions earned from the sale of Sponsored REIT preferred shares
amounted to approximately $10,693,000 for the year ended December 31, 2006. As
of March 14, 2007, sales commissions from the sale of Sponsored REIT preferred
shares amount to approximately $1,196,000 during 2007.

During 2006 and 2007, the Company provided interim financing for the purchase of
certain Sponsored REIT properties, and development services prior to completion
of the Sponsored REITs' private equity offerings. The Sponsored REITs paid the
Company financing commitment fees of approximately $9,785,000 and development
fees of approximately $51,000 for the year ended December 31, 2006. As of March
14, 2007, the Sponsored REITs paid the Company financing commitment fees of
approximately $995,000 during 2007. Interest income earned from loans to the
Sponsored REITs amounted to approximately $2,050,000 for the year ended December
31, 2006. As of March 14, 2007, the interest income earned from loans to the
Sponsored REITs during 2007 amounted to approximately $2,085,000. The interest
rate charged by the Company to the Sponsored REITs is equal to, and generally
offset by, the interest rate paid by the Company to Citizens Bank for borrowings
under its line of credit, though from time-to-time the Company may use its own
cash to finance a portion of the loan from which it earns interest at the same
rate as the line of credit. Interest income earned by the Company from
investments of its own cash for the year ended December 31, 2006 was $305,000.
As of March 14, 2007, the interest income earned by the Company from investments
of its own cash amounted to approximately $388,000. All loans to Sponsored REITs
in 2006 were evidenced by promissory notes and were paid in full upon closing of
the applicable Sponsored REIT's private equity offering during 2006.

offerings of 2006 Target Stock and on the same terms as other stockholders of

                            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 2007.
Ernst & Young has served as the Company's independent registered public
accounting firm since May 2003.

Representatives of Ernst & Young LLP are expected to be present at the Annual
Meeting and will have the opportunity to make a statement if they desire to do

                                       27


Report of the Audit Committee of the Board of Directors

The audit committee reviewed the Company's audited consolidated financial
statements for the year ended December 31, 2006 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 Oversight 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,
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 registered public accounting
            firm's 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 to be discussed by the Statement
on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1,
AU section 380), as adopted by the Public Company Accounting Oversight Board in
Rule 3200T, with Ernst & Young LLP, the Company's independent registered public
accounting firm for the year ended December 31, 2006. SAS 61 requires the
Company's independent registered public accounting firm to discuss with the
Company's audit committee, among other things, the following:

      o     methods to account for significant unusual transactions;


                                       28


      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), as adopted by the Public Company Accounting Oversight Board in Rule
3600T. 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 auditor's 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 referred to
above, 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, 2006.

Corp.

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

(1)   Audit fees consist of fees for the audit of our financial statements, the

      services. Tax compliance services, which relate to the preparation of tax
      returns, claims for refunds and tax payment-planning services, were not
      incurred in 2006 and accounted for $173,500 of the total tax fees incurred
      in 2005.

(4)   The Company was not billed by its independent registered public accounting
      firm in 2006 or 2005 for any other fees.

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.


                                       30


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.

                                 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, internet,
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

In accordance with Rule 14a-8 of the Exchange Act, proposals of stockholders
intended to be included in the Company's proxy statement for the 2008 Annual
Meeting of Stockholders must be received by the Company at its principal office
not later than December 4, 2007. In accordance with our bylaws, if a stockholder
who wishes to make a proposal at the 2008 Annual Meeting--other than one that
will be included in the Company's proxy materials--does not notify the Company
by no earlier than December 4, 2007 and no later than January 3, 2008, 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.


                                       31


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,

                             /s/ Barbara J. Fournier

                             Barbara J. Fournier, Secretary

March 23, 2007


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
