About Franklin Street Properties Corp.
​
Our company, Franklin Street Properties Corp. (sometimes referred to as the “Company,” “FSP,” “Franklin Street Properties,” “we,” “us,” or “our”) is a Maryland corporation that operates in a manner intended to qualify as a real estate investment trust (“REIT”) for federal income tax purposes. Our common stock is traded on the NYSE American under the symbol “FSP”.
Our current strategy is to invest in infill and central business district office properties in the United States Sunbelt and Mountain West regions as well as select opportunistic markets. We believe that the United States Sunbelt and Mountain West regions have macro-economic drivers that have the potential to increase occupancies and rents. We seek value-oriented investments with an eye towards long-term growth and appreciation, as well as current income.
From time-to-time we may acquire real estate or invest in real estate by making secured loans on real estate. We may also pursue on a selective basis the sale of our properties to take advantage of the value creation and demand for our properties, or for geographic or property specific reasons.
We continue to believe that the current price of our common stock does not accurately reflect the value of our underlying real estate assets and will continue to seek to increase shareholder value by (1) pursuing the sale of select properties where we believe that short to intermediate term valuation potential has been reached and (2) striving to lease vacant space. During 2022, our property dispositions resulted in aggregate gross proceeds of approximately $130 million and we repaid approximately $152 million in debt. We intend to use the proceeds from any future dispositions primarily for the repayment of debt.

Franklin Street Properties strives to maximize stockholder value through the prudent application of sound environmental, social and governance (ESG) actions. We believe that our efforts in ESG have the potential to not only improve the health of our planet, but also to save money on operating expenses, increase tenant and employee retention and reduce company risk.

Franklin Street Properties utilizes the Environmental Protection Agency’s ENERGY STAR® program to track our progress in energy efficiency. As of year-end 2022, over 69% of our square footage, both directly-owned and asset-managed by Franklin Street Properties, had earned the ENERGY STAR® label, denoting energy performance among the top 25% of similar properties.
As of year-end 2022, approximately 66% of our square footage, both directly-owned and asset-managed by Franklin Street Properties, had been awarded some level of LEED certification. The majority of our buildings have achieved LEED Gold certification and one of our buildings has achieved LEED Platinum certification, which is the highest level of certification.
ADDITIONAL ESG INFORMATION
We are committed to transparent reporting of ESG information. More detailed ESG information is available on our website at http://www.fspreit.com under the heading “ESG”.

All shares of Common Stock owned by you as of the Record Date may be voted by you. These shares include those (1) held directly in your name as a stockholder of record and (2) held for you as the beneficial owner through a broker, financial institution or other nominee.
Most of the stockholders of Franklin Street Properties hold their shares in “street name” through a broker, financial institution or other nominee rather than directly in their own name. As summarized below, there are some distinctions between being a “record” holder and being a “beneficial” holder of our shares.
6. What does it Mean to be a Stockholder of Record?
​
If, on the Record Date, your shares of Common Stock are registered directly in your name with Franklin Street Properties’ transfer agent, American Stock Transfer & Trust Company, you are considered the stockholder of record of those shares, and the Notice or set of printed proxy materials, as applicable, is being sent directly to you. As the stockholder of record, you have the right to grant your voting proxy directly to the persons named in the proxy card or to vote online during the Annual Meeting. If you request a paper copy of the materials as described in the Notice, a proxy card will be sent to you with those materials.
7. What does it Mean to Beneficially Own Shares in Street Name?
​
If, on the Record Date, your shares of Common Stock are held in a brokerage account by a broker, financial institution or other nominee, you are considered the beneficial owner of shares held on your behalf in “street name”, and the Notice or set of printed proxy materials, as applicable, is being forwarded to you by your broker, financial

institution or other nominee who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, financial institution or other nominee on how to vote the shares held in your account. You should receive information from your broker, financial institution or other nominee on how you can direct the voting of your shares. If you request a paper copy of the proxy materials as indicated in the Notice, your broker, financial institution or other nominee will provide a voting instruction card for you to use to direct the voting of your shares. As a beneficial owner, you may virtually attend the Annual Meeting and vote your shares online while attending the virtual Annual Meeting by following the instructions set forth below in “How do I Vote?”.
8. Why are we Holding a Virtual Annual Meeting and How Do I Attend?
​
In light of continuing health concerns about the COVID-19 pandemic, this year’s Annual Meeting will be conducted as a virtual meeting solely via live audio webcast on the internet. You are entitled to participate in the virtual Annual Meeting only if you were a stockholder of Franklin Street Properties as of the close of business on the Record Date for the Annual Meeting. You will be able to attend the Annual Meeting online and vote and submit questions online during the meeting by visiting www.virtualshareholdermeeting.com/FSP2023. You will not be able to attend the Annual Meeting in person. The audio webcast will start at 11:00 a.m. Eastern Time on May 11, 2023. You will need the 16-digit control number included on your Notice, proxy card or voting instruction form in order to be able to attend the Annual Meeting online. Online access to the audio webcast will open at 10:45 a.m. Eastern Time to allow time for you to log in and test your device’s audio system. We encourage you to access the meeting prior to the start time. If you encounter any difficulties accessing the virtual Annual Meeting during check-in or the meeting, please call the technical support number that will be posted on the virtual meeting log-in page. We will have technicians available to assist you.
We have designed our virtual Annual Meeting format to enhance, rather than to constrain, stockholder access, participation and communication. For example, the virtual Annual Meeting format allows stockholders, regardless of location, to communicate with us during the Annual Meeting so they can ask questions of our Board or management, as time permits. In addition, a representative of our auditor, Ernst & Young LLP, will also attend the virtual Annual Meeting and will be available to answer appropriate questions at that time. We believe that the virtual Annual Meeting will provide stockholders with at least the same rights and opportunities to participate as they would have at an in-person meeting. We remain committed to returning to hold our annual meetings in person under normal circumstances.
9. How do I Vote?
​
Voting at the virtual Annual Meeting. If you attend the virtual Annual Meeting, you may vote your shares of Common Stock online at the time of the Annual Meeting by visiting www.virtualshareholdermeeting.com/FSP2023. To participate and vote during the virtual Annual Meeting, stockholders of record will need the 16-digit control number included on your Notice or on your proxy card. Beneficial stockholders who do not have a control number may gain access to and vote at the virtual Annual Meeting by logging into their broker, brokerage firm, bank or other nominee’s website and selecting the stockholder communications mailbox to access the virtual Annual Meeting; instructions should also be provided on the voting instruction card provided by your broker, bank, or other nominee. Even if you plan to attend the virtual Annual Meeting, we recommend that you vote your shares in advance, so that your vote will be counted if you later decide not to attend the virtual Annual Meeting.
Voting by Proxy for Shares Registered Directly in the Name of the Stockholder. If you are a stockholder of record, you may instruct the proxy holders named in the proxy card how to vote your shares of Common Stock in one of the following ways:
•
Vote by Internet. You may vote via the Internet by following the instructions provided in the Notice or, if you received printed materials, on your proxy card. The website for Internet voting is www.proxyvote.com and is also printed on the Notice and on your proxy card. Please have your Notice or proxy card in hand. Internet voting is available 24 hours per day until 11:59 p.m., Eastern Time, on May 10, 2023. You will receive a series of instructions that will allow you to vote your shares of Common Stock. You will also be given the opportunity to confirm that your instructions have been properly recorded. IF YOU VOTE VIA THE INTERNET, YOU DO NOT NEED TO RETURN YOUR PROXY CARD.
​
•
Vote by Telephone. If you received printed copies of the proxy materials, you also have the option to vote by telephone by calling the toll-free number listed on your proxy card. Telephone voting is available 24

hours per day until 11:59 p.m., Eastern Time, on May 10, 2023. When you call, please have your proxy card in hand. You will receive a series of voice instructions that will allow you to vote your shares of Common Stock. You will also be given the opportunity to confirm that your instructions have been properly recorded. If you did not receive printed materials and would like to vote by telephone, you must request printed copies of the proxy materials by following the instructions on your Notice. IF YOU VOTE BY TELEPHONE, YOU DO NOT NEED TO RETURN YOUR PROXY CARD.
•
Vote by Mail. If you received printed materials and would like to vote by mail, then please mark, sign and date your proxy card and return it promptly in the postage-paid envelope provided with your printed materials. If you did not receive printed materials and would like to vote by mail, you must request printed copies of the proxy materials by following the instructions on your Notice.
​
Voting by Proxy for Shares Registered in Street Name. If your shares of Common Stock are held in “street name”, you will receive instructions from your broker, financial institution or other nominee that you must follow in order to have your shares of Common Stock voted as you direct. Those instructions may have accompanied these printed materials.
10. What are the Quorum and Voting Requirements for the Proposals?
​
The presence, in person or by proxy, of holders of at least a majority of the total number of outstanding shares of Common Stock entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting. Shares present virtually during the Annual Meeting will be considered shares of Common Stock represented in person at the meeting. As of the Record Date, there were 103,235,914 shares of Common Stock outstanding and entitled to vote at the Annual Meeting. Abstentions and broker non-votes (described below), if any, will be considered present for the purpose of determining the presence of a quorum.
The affirmative vote of a majority of the total votes cast for and against as to each nominee for director is required to approve the election of each nominee for director in Proposal 1. In addition, a majority of the votes cast at the Annual Meeting is required for approval of the ratification of the appointment of the independent registered public accounting firm (Proposal 2), approval of the advisory vote on executive compensation (Proposal 3) and approval of one of the three frequency options under the advisory vote on the frequency of future executive compensation advisory votes (Proposal 4), each of which is a non-binding vote. With respect to Proposal 4, if none of the three frequency options receives the vote of the holders of a majority of the votes cast, we will consider the frequency option (one year, two years or three years) receiving the highest number of votes cast by stockholders to be the frequency that has been recommended by stockholders, even if the frequency selected receives less than a majority of the total votes cast on the proposal.
Broker non-votes occur when brokers, financial institutions or other nominees do not receive voting instructions from their customers on how to vote the customers’ shares on a proposal and the broker, financial institution or other nominee does not have discretionary voting authority or chooses not to exercise it with respect to a proposal. If you hold shares in “street name” and you do not give instructions as to how to vote your shares, your broker, financial institution or other nominee may have authority to vote your shares on certain routine matters but not on non-routine matters. Proposal 2 is a routine proposal, and your broker, financial institution or other nominee has discretionary voting authority to vote on that proposal. Your broker, financial institution or other nominee does not have discretionary voting authority with respect to any of the other proposals on the ballot: the election of directors (Proposal 1), the advisory vote on executive compensation (Proposal 3) and the advisory vote on the frequency of future executive compensation advisory votes (Proposal 4).
11. What if I Change my Mind after I have Voted?
​
You may revoke your proxy and change your vote at any time before it is voted at the Annual Meeting by (1) sending a written notice of revocation to our Secretary at the Company’s address set forth in this Proxy Statement that is received prior to the time at which your proxy is voted at the Annual Meeting and submitting a new written proxy bearing a date later than the date of the proxy being revoked; (2) voting again on the Internet or by telephone prior to 11:59 p.m. Eastern Time on Wednesday, May 10, 2023; or (3) attending the virtual Annual Meeting online and voting electronically during the virtual Annual Meeting. Attendance at the virtual Annual Meeting online will not, in itself, constitute revocation of a previously granted proxy.
FRANKLIN STREET PROPERTIES CORP. | 2023 PROXY STATEMENT 11

TABLE OF CONTENTS​

​ | QUESTIONS AND ANSWERS | ​

If you hold your shares in “street name”, then you may submit new voting instructions by contacting your broker, financial institution or nominee. You may also vote online while virtually attending the Annual Meeting, which will have the effect of revoking any previously submitted voting instructions.
12. How will my Shares be Voted if I do not Return my Proxy or do not Provide Specific Instructions in the Proxy Card that I Submit?
​
If you are a stockholder of record, your shares will not be voted if you do not vote over the Internet, by telephone, by returning your proxy or by voting electronically during the virtual Annual Meeting. If you submit a proxy card without giving specific voting instructions on one or more proposals listed in the notice for the Annual Meeting, your shares will be voted as recommended by our Board on such proposals, and as the proxy holders may determine in their discretion how to vote with respect to any other proposals properly presented for a vote at the Annual Meeting.
If your shares are held in “street name” at a broker, your broker may under certain circumstances vote your shares on routine proposals, including Proposal 2, if you do not timely provide voting instructions in accordance with the instructions provided by them. However, if you do not provide timely instructions, your broker does not have the authority to vote on non-routine proposals, including Proposals 1, 3 and 4, at the Annual Meeting and a “broker non-vote” would occur.
13. Where do I Find the Voting Results of the Annual Meeting?
​
We will announce preliminary voting results at the Annual Meeting. We will also publish preliminary or, if available, final voting results within four business days of the Annual Meeting in a Current Report on Form 8-K to be filed with the SEC. If necessary, we will publish final voting results within four business days after the final voting results are known in an amendment to Current Report on Form 8-K to be filed with the SEC. Copies of the Current Report on Form 8-K and any amendments thereto to be filed with the SEC will be available on our website at: http://www.fspreit.com and on the SEC’s website at http://www.sec.gov.
14. Will other Matters be Voted on at the Annual Meeting?
​
We are not currently aware of any other matters to be presented at the Annual Meeting other than those described in this Proxy Statement. If any other matters not described in the Proxy Statement are properly presented at the Annual Meeting, any proxies received by us will be voted in the discretion of the proxy holders.
15. How do I Submit a Question at the Virtual Annual Meeting?
​
During the Annual Meeting, you can view our agenda and rules of conduct and procedures and submit questions at www.virtualshareholdermeeting.com/FSP2023. Stockholders must have their 16-digit control number to submit questions. During the Annual Meeting, we intend to answer all questions submitted that are pertinent to the Company and the items being voted on by stockholders, as time permits and in accordance with our rules of conduct and procedures. If we are unable to respond to a stockholder’s properly submitted question due to time constraints, we will either post the response on the investor relations section of our website following the Annual Meeting, or respond directly to that stockholder using the contact information provided. The business of the Annual Meeting will be taken up as set forth in the agenda. When an item on the agenda is before the Annual Meeting for consideration, appropriate and relevant questions will be addressed at that time. We will seek to limit the discussion of each agenda item to no more than 10 minutes. If a stockholder has a question that is not related to an agenda item, the question will be deferred to the question and answer session after the formal portion of the Annual Meeting. We reserve the right to end the question and answer session of the Annual Meeting after a reasonable amount of time. At the appropriate time, we will read out the applicable questions and will provide responses as necessary. Substantially similar questions will be answered only once. To promote fairness and due to time constraints, we will respond to no more than two questions from any single stockholder.

Communications and Stockholder Proposals
16. How can I Communicate with the Company’s Directors?
​
Our Board will give appropriate attention to written communications that are submitted by stockholders and will respond if and as appropriate. The Secretary of Franklin Street Properties 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 we may receive repetitive or duplicative communications.
Stockholders who wish to send communications on any topic to our Board should address such communications to Board of Directors, Franklin Street Properties Corp., 401 Edgewater Place, Suite 200, Wakefield, Massachusetts 01880, Attn: Scott H. Carter, Secretary.
17. How do I Submit a Proposal for Action at the 2024 Annual Meeting?
​
In accordance with Rule 14a-8 of the Exchange Act, proposals of stockholders intended to be included in our proxy statement and form of proxy for the 2024 Annual Meeting of Stockholders must be received by Franklin Street Properties at its principal office not later than December 1, 2023. In addition, according to our current bylaws, any stockholder proposal intended to be presented at an annual meeting, including nominations for election to the Board, but not considered for inclusion in our proxy statement relating to such meeting, must be received at Franklin Street Properties’ principal office not earlier than the 150th day nor later than 5:00 p.m., Eastern Time, on the 120th day prior to the first anniversary of the mailing date of the preceding year’s proxy materials. For the 2024 Annual Meeting of Stockholders, that means that a stockholder must deliver proper notice of a proposed nominee or action that is proposed to be presented at the 2024 Annual Meeting of Stockholders but not be included in the proxy statement for such meeting to the Secretary of Franklin Street Properties between November 1, 2023 and December 1, 2023. In addition to the timing of the delivery of the notice, our bylaws include specific information that must be provided (including the information required by Rule 14a-19 under the Exchange Act) and procedures that must be followed to submit a proposal.

CORPORATE GOVERNANCE
We operate within a comprehensive corporate governance structure that includes the highest standards of professional and personal conduct. Our Corporate Governance Guidelines, our Code of Business Conduct and Ethics, the charters of our Audit, Compensation, and Nominating and Corporate Governance Committees, and other corporate governance information, are available on our website at http://www.fspreit.com under the heading “Investor Relations” and then under the subheading “Governance Documents” under “Corporate Information.” The information on our website is not a part of this Proxy Statement and is not incorporated into any of our filings made with the SEC.
Introduction
​
Our Common Stock trades on NYSE American under the symbol “FSP”. We began trading on the American Stock Exchange in June 2005. The exchange’s name was changed to NYSE Amex after it was acquired by NYSE Euronext on October 1, 2008, was later known as NYSE MKT and is now NYSE American.
Board of Directors
​
Franklin Street Properties is currently managed by an eight member Board. All directors are elected to serve one-year terms (in all cases subject to the election and qualification of their successors or to their earlier death, resignation or removal).
Director Independence
​
Under the NYSE American corporate governance standards, set out in the NYSE American LLC Company Guide (the “NYSE American Rules”), at least a majority of the Board must be “independent directors” as defined in Section 803A of the NYSE American Rules. According to Section 803A, “independent director” means a person other than an executive officer or employee of Franklin Street Properties. In addition, to qualify as an “independent director,” the Board of Directors must affirmatively determine that the director does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Section 803A of the NYSE American Rules also includes the following non-exclusive list of persons who shall not be considered independent:
a.
a director who is, or during the past three years was, employed by us, other than prior employment as an interim executive officer (provided the interim employment did not last longer than one year);
​
b.
a director who accepted or has an immediate family member who accepted any compensation from us in excess of $120,000 during any period of twelve consecutive months within the three years preceding the determination of independence, other than the following:
​
i.
compensation for Board or Board committee service,
​
ii.
compensation paid to an immediate family member who is an employee (other than an executive officer) of Franklin Street Properties,
​
iii.
compensation received for former service as an interim executive officer (provided the interim employment did not last longer than one year), or
​
iv.
benefits under a tax-qualified retirement plan, or non-discretionary compensation;
​
c.
a director who is an immediate family member of an individual who is, or at any time during the past three years was, employed by us as an executive officer;
​
d.
a director who is, or has an immediate family member who is, a partner in, or a controlling shareholder or an executive officer of, any organization to which we made, or from which we received, payments (other than those arising solely from investments in our securities or payments under non-discretionary charitable contribution matching programs) that exceed 5% of the organization’s consolidated gross revenues for that year, or $200,000, whichever is more, in any of the most recent three fiscal years;
​

e.
a director who is, or has an immediate family member who is, employed as an executive officer of another entity where at any time during the most recent three fiscal years any of our executive officers serve on the compensation committee of such other entity; or
​
f.
a director who is, or has an immediate family member who is, a current partner of our outside auditor, or was a partner or employee of our outside auditor who worked on our audit at any time during any of the past three years.
​
For purposes of Section 803A of the NYSE American Rules, “immediate family member” includes a person’s spouse, parents, children, siblings, mother-in-law, father-in-law, brother-in-law, sister-in-law, son-in-law, daughter-in-law, and anyone who resides in such person’s home (other than domestic employees).
Because Mses. Murray and O’Neil and Messrs. Burke, Hansen, Hoxsie, McGillicuddy and Wilkins do not have any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director, our Board has determined that they are “independent directors” for purposes of the NYSE American Rules.
Board Meetings, Annual Meeting of Stockholders, and Attendance
​
During 2022, each director attended more than 75% of the meetings of the Board and of the committees on which he or she served. The Board held seven meetings in 2022.
Each of our directors then serving on the Board attended the 2022 Annual Meeting of Stockholders.
Current Board Leadership Structure
​
At the present time, our Board has chosen to combine the Chairman and Chief Executive Officer positions. Our Board believes that George J. Carter is best suited to serve as both Chairman and Chief Executive Officer because he is most familiar with Franklin Street Properties’ business and industry and is most capable of effectively identifying strategic priorities and leading the discussion and execution of strategy. Mr. Carter has served as Chief Executive Officer and Chairman since he founded Franklin Street Properties, originally Franklin Street Partners Limited Partnership. Our Board believes that independent directors and management have different perspectives and roles in our strategy development. Our independent directors bring experience, oversight and expertise from outside Franklin Street Properties and its industry, while the Chief Executive Officer brings company-specific experience and expertise. Our Board believes that, at the present time, the combined role of Chairman and Chief Executive Officer is in the best interests of Franklin Street Properties and our stockholders and is consistent with good corporate governance. The combined role promotes strategy development and execution and facilitates information flow between management and the Board, which are essential to effective governance. Our Board encourages strong communication among all of its independent directors and the Chairman and Chief Executive Officer, and our Board believes that it has been able to, and will continue to, effectively provide independent oversight of our business and affairs, including the risks we face, through the role of our Lead Independent Director, the independent committees of our Board, the overall composition of our Board and contributions from all of our independent directors and other corporate governance policies in effect.
Lead Independent Director
​
Since February 7, 2014, Georgia Murray has served as Lead Independent Director. The Lead Independent Director’s duties include: coordinating the activities of our independent directors, coordinating the agenda for and chairing sessions of our independent directors, serving as the principal liaison for consultation and communication between our independent directors and our stockholders, facilitating communications between our independent directors, the other members of our Board and our management, and performing such other duties as our Board may from time to time delegate. In performing the duties described above, the Lead Independent Director is expected to consult with the chairs of the appropriate Board committees and solicit their participation in order to avoid diluting the authority or responsibility of such committee chairs.

The Board’s Role in Succession Planning
​
The Board expects management to have an ongoing program for effective senior leadership development and succession. As reflected in our Corporate Governance Guidelines, the Board works on a periodic basis with the Chief Executive Officer to review, maintain and revise, if necessary, the Company’s succession plan upon the conclusion of the Chief Executive Officer’s service as our Chief Executive Officer for any reason. The Chief Executive Officer reports periodically to the Board on succession planning for the Chief Executive Officer and senior management positions, which report includes a discussion of assessments, leadership development plans and other relevant factors.
The Board’s Role in Risk Oversight
​
Our Board has the primary responsibility for overseeing the Company’s risk management processes. A portion of this responsibility has been delegated by the Board to the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee, each with respect to the assessment of the risks and risk management in their respective areas of oversight. In general, our Board oversees risk management activities relating to business strategy, acquisitions, dispositions, capital allocation, organizational structure and certain operational risks. Our Audit Committee oversees risk management activities related to financial controls, legal and compliance risks and potential cyber-attacks and intrusions; our Compensation Committee oversees risk management activities relating to our compensation policies and practices; and our Nominating and Corporate Governance Committee oversees risks relating to our nominating and corporate governance policies and practices. Each committee reports to the full Board on a regular basis, including reports with respect to the committee’s risk oversight activities as appropriate. These committees and the full Board focus on the most significant risks facing the Company and the Company’s general risk management strategy, and also ensure that risks undertaken by the Company are consistent with the Board’s appetite for risk. While the Board oversees the Company’s risk management, the Company’s management is responsible for day-to-day risk management processes. We believe this division of responsibilities is the most effective approach for addressing the risks facing the Company and that the leadership structure of our Board supports this approach. The Board and each of our committees regularly discusses with management our major risk exposures, their potential financial impact on Franklin Street Properties, and the steps we take to manage them. The Board and each of our committees exercise their oversight responsibilities in a variety of ways, but in all cases our directors are informed by regular reports from the Company’s management that are intended to identify key risks and our strategies to mitigate them.
Executive Sessions
​
Each director has the right to call an executive session without management participation after each regularly scheduled meeting of the entire Board and at such other times that the directors deem such a meeting to be appropriate. Similarly, each independent director has the right to call an executive session with only independent directors present after each regularly scheduled meeting of the entire Board and at such other times that an independent director deems appropriate. At a minimum, the independent directors meet in executive session at least annually without the presence of non-independent directors and management.
Committees of the Board
​
Our Board has the following three standing committees: (1) Audit, (2) Compensation and (3) Nominating and Corporate Governance. The membership and the function of each of these committees are described below.

​ | Audit | ​ | ​ | Compensation | ​ | ​ | Nominating and Corporate Governance | ​

Audit Committee. Our Board has established an Audit Committee which operates pursuant to a charter approved by our Board and that is reviewed and reassessed at least annually. The Audit Committee, among other functions, (1) has the sole authority to appoint, evaluate, terminate and determine the compensation of our independent registered public accounting firm, (2) reviews with our independent registered public accounting firm the scope and results of the audit engagement, (3) approves professional services provided by our independent registered public accounting firm, (4) reviews the independence of our independent registered public accounting firm, (5) reviews and approves our policies and procedures for reviewing and approving or ratifying related person transactions, (6) reviews and approves our entry into swaps and (7) oversees our cyber risk management. Our Board has determined that each member of the Audit Committee is “independent” as that term is defined under the NYSE American Rules, including the independence requirements contemplated by Rule 10A-3 under the Exchange Act. Our Board determined that Mr. Burke qualifies as an “audit committee financial expert” as that term is defined in the rules of the SEC. The Audit Committee Report is included later in this Proxy Statement. The Audit Committee met five times during 2022.
Compensation Committee. Our Board has established a Compensation Committee which operates pursuant to a charter that was approved by our Board and that is reviewed and reassessed at least annually. Our Board has determined that each member of the Compensation Committee has been determined to be “independent” under the NYSE American Rules, including the independence requirements under Rule 10C-1 under the Exchange Act. The Compensation Committee’s responsibilities include, among other duties, the responsibility to (1) review and approve the corporate goals and objectives relevant to the compensation of the Chief Executive Officer, (2) evaluate the performance of the Chief Executive Officer in light of such goals and objectives and either determine and approve or recommend to our Board for approval the compensation of the Chief Executive Officer based on such evaluation, (3) oversee the evaluation of our other executive officers, (4) review and approve the compensation of our other executive officers, (5) review and make recommendations to our Board with respect to incentive compensation and equity-based plans, (6) review and make recommendations to our Board with respect to the compensation of our non-employee directors and (7) perform other functions or duties deemed appropriate by the Board.
The Compensation Committee is authorized to retain and terminate any compensation consultant to assist in the evaluation of executive officer compensation and to approve the consultant’s fees and other retention terms and to pay the compensation without further action by the Board. The Compensation Committee also has authority to retain or obtain the advice of compensation consultants, legal counsel and other advisors as the Compensation Committee deems necessary or appropriate, and is responsible for assessing the independence of such consultants and advisors, overseeing the work of such consultants and advisors and authorizing the payment of such consultants and advisors. The Compensation Committee makes all compensation decisions relating to compensation of our executive officers other than the Chief Executive Officer and makes a recommendation regarding the compensation of our Chief Executive Officer to the Board. The Chief Executive Officer is not permitted to be present during any deliberations or voting relating to the Chief Executive Officer’s compensation. The Compensation Committee takes into consideration recommendations made by the Chief Executive Officer with respect to compensation decisions relating to executive officers other than the Chief Executive Officer. The Compensation Committee Report is included later in this Proxy Statement.
The Compensation Committee met four times during 2022.
Nominating and Corporate Governance Committee. Our Board has established a Nominating and Corporate Governance Committee which operates pursuant to a charter approved by our Board and is reviewed and reassessed by the Nominating and Corporate Governance Committee at least annually. The Nominating and Corporate Governance Committee is responsible for identifying and recommending individuals to become members of our Board, periodically reviewing our Corporate Governance Guidelines and other corporate governance documents and recommending any changes, as well as ensuring that we are in compliance with all corporate governance and listing standards of the NYSE American. The Nominating and Corporate Governance Committee is also responsible for overseeing the annual evaluation of the Board. The Nominating and Corporate Governance Committee is authorized to retain advisors and consultants and to compensate them for their services.
The Nominating and Corporate Governance Committee met three times during 2022.
General Committee Information. A copy of each of our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee Charters is available on our website at http://www.fspreit.com under the heading “Investor Relations” and then under the subheading “Governance Documents” under “Corporate Information.” In addition, our Board adopted Corporate Governance Guidelines, a copy of which is available in the same place on our website.

TABLE OF CONTENTS​

​ | CORPORATE GOVERNANCE | ​

Our Board may from time to time establish other special or standing committees to facilitate the management of Franklin Street Properties or to discharge specific duties delegated to a committee by the full Board.
Director Nomination Process
​
The process followed by the Nominating and Corporate Governance Committee to identify and evaluate director candidates includes requests to our directors 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 our directors. The Nominating and Corporate Governance Committee has established director qualification standards for consideration in recommending candidates to our Board. The Nominating and Corporate Governance Committee is responsible for reviewing with our Board, on an annual basis, the appropriate characteristics, skills and experience required for our Board as a whole and its individual members.
In evaluating the suitability of individual candidates (both new candidates and current members of our Board), the Nominating and Corporate Governance Committee, in recommending candidates for election, and our Board, in approving the nomination of (and, in the case of vacancies, electing) such candidates, may take into account a variety of subjective factors, including, without limitation:
(1)
personal and professional integrity, ethics and values;
​
(2)
experience in corporate management, such as serving as an officer or former officer of a publicly-held company, and a general understanding of marketing, finance and other elements relevant to the success of a publicly-traded company in today’s business environment;
​
(3)
experience in our industry and/or in an industry or industries that may be beneficial to us;
​
(4)
experience as a board member of another publicly-held company;
​
(5)
academic expertise in an area of our operations;
​
(6)
practical and mature business judgment, including ability to make independent analytical inquiries; and
​
(7)
any relationships, financial, professional or social in nature, that a candidate may have with members of management or other board members in so far as they may affect the independence of such candidate.
​
Consideration of Board Diversity. Our Corporate Governance Guidelines provide that, when evaluating candidates for nomination as new directors, the Nominating and Corporate Governance Committee will ensure that the initial list from which new directors are chosen (the “Initial List”) includes (but need not be limited to) qualified candidates reflecting a diversity of race, ethnicity and gender (and any third-party consultant requested to furnish an Initial List will be asked to include such candidates). The Nominating and Corporate Governance Committee and our Board believe that diversity with respect to viewpoint, skills and experience also should be an important factor in board composition. The Nominating and Corporate Governance Committee and our Board discuss diversity considerations in connection with each potential nominee, as well as on a periodic basis in connection with the composition of our Board as a whole. The Nominating and Corporate Governance Committee and our Board do not assign specific weight to particular factors, and no particular factor is a prerequisite for each prospective nominee. The Nominating and Corporate Governance Committee and our Board believe 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 our Board to fulfill its responsibilities. Our Board evaluates each individual in the context of our Board as a whole, with the objective of assembling a group that can best perpetuate the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas. In determining whether to recommend a director for re-election, the Nominating and Corporate Governance Committee also considers the director’s past attendance at meetings and participation in and contributions to the activities of our Board and Board refreshment objectives.
Board Diversity Update. In February 2023, our Board agreed that we would seek to fill the next vacancy on our Board with a qualified gender diverse candidate. We are pleased to report that two of our three newest directors enhanced our Board’s gender and racial/ethnic diversity. The Board intends to continue to emphasize diversity in all its forms in its refreshment efforts.

Board Refreshment
​
Board refreshment over time assists the Board in maintaining an appropriate balance of tenure, diversity, experience, skills and new ideas needed to provide effective oversight in light of the Company’s current and future strategic needs. The Company benefits when there is a mix of directors with a history of service with the Company and newer directors who bring a fresh perspective and new ideas.
Stockholder Recommendations and Board Nominations
​
Stockholders may recommend individuals to our Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials to our principal office, 401 Edgewater Place, Suite 200, Wakefield, Massachusetts 01880, Attn: Scott H. Carter, Secretary. Assuming that appropriate biographical and background material has been provided on a timely basis, our Nominating and Corporate Governance 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 our 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 our Nominating and Corporate Governance Committee or Board, by following the procedures set forth below under “Other Information — Stockholder Proposals.”
Stockholder Power to Amend Bylaws
​
The Company’s bylaws provide stockholders with the power to amend the Company’s bylaws by the affirmative vote of a majority of all votes entitled to be cast on the matter pursuant to a binding proposal that is properly submitted by stockholders for approval at a duly called annual or special meeting of stockholders.
Anti-Hedging Policy
​
Our Anti-Hedging Policy prohibits any director, officer or employee of FSP, or family member of any of the foregoing who share the same address as, or are financially dependent on, any of the foregoing, or any other person who shares the same address as any of the foregoing, other than a tenant or employee, and including any and all corporations, partnerships, trusts or other entities owned or controlled by any of the foregoing, from engaging in short sales of Company securities, including short sales “against the box”, or purchases or sales of puts or calls involving Company securities.
Code of Business Conduct and Ethics
​
Franklin Street Properties is committed to establishing and maintaining an effective ethics and compliance program that is intended to increase the likelihood of preventing, detecting, and correcting ethical lapses and violations of law or Company policy. The Company has adopted a Code of Business Conduct and Ethics (the “Code”) which applies to all officers and employees, as well as to our Board.
The Code is available on the Company’s website at http://www.fspreit.com under the heading “Investor Relations” and then under the subheading “Governance Documents” under “Corporate Information.” We will disclose amendments to, or waivers of our Code that are required to be disclosed under the securities rules, by posting such information on the Company’s website, www.fspreit.com. Any waiver of our Code for directors or executive officers must be approved by the Board. The Company did not grant any such waivers during 2022 and does not anticipate granting any such waivers during 2023.

DIRECTOR COMPENSATION AND STOCK
OWNERSHIP REQUIREMENTS
The Compensation Committee of the Board is responsible for reviewing and recommending to the Board the form and amount of compensation for our non-employee directors. Since October 2019, we have had the following compensation program for non-employee directors:

​ | ​ | Non-employee Director Compensation | ​ | ​
​ | ​ | Annual Cash Retainer | ​ | ​ | ​ | ​ | $ | 56,250 | ​ | ​ | ​
​ | ​ | Additional Annual Cash Retainer – Lead Independent Director | ​ | ​ | ​ | ​ | $ | 15,000 | ​ | ​ | ​

​
(1)
Reflects the grant date fair value. Fair value is the closing price of FSP Common Stock on the date of the grant.
​
Our Annual and Additional Cash Retainers are paid to our non-employee directors in four equal installments each year. We also reimburse our non-employee directors for expenses incurred by them in connection with attendance at Board meetings.
2022 Non-Employee Director Compensation
​
In December 2022, the Compensation Committee recommended, and the Board agreed, that our non-employee directors should forgo what would have been the fourth installment of their 2022 Annual and Additional Cash Retainers, as applicable. This resulted in reductions to total compensation to non-employee directors in the range of approximately 13% to 14% during 2022 compared to 2021. While the Compensation Committee and the Board acknowledged that broad macroeconomic factors had negatively impacted both the business operations and the stock performance of many office REITs during 2022, including FSP, they determined that a downward adjustment to non-employee director compensation was appropriate in light of the various adverse impacts that all FSP stakeholders experienced during 2022.
The following table provides information regarding non-employee director compensation during 2022:

Non-employee Director Stock Ownership Requirements
​
The Board believes that all non-employee directors should maintain a meaningful personal financial stake in the Company to align their long-term interests with those of our stockholders. Pursuant to our Corporate Governance Guidelines, non-employee directors are required to own shares of Common Stock valued at five times the cash portion of their Annual Cash Retainer (excluding any Additional Cash Retainers payable for serving as a committee chair or attendance at meetings).
For purposes of determining compliance with these requirements, the “value” of Common Stock shall be determined using the greater of (i) the actual cost basis of such shares or (ii) the Company’s average closing stock price for the preceding calendar year.
Non-employee directors serving as of February 7, 2014 (the date of initial adoption of these requirements) had until February 7, 2021, seven years following the initial adoption of these requirements, to meet the minimum ownership requirements. Non-employee directors who are elected or appointed after the initial adoption of these requirements will have seven years from the time they are elected or appointed to meet the minimum ownership requirements.
If an individual becomes subject to an increased ownership amount due to an increase in the Annual Cash Retainer, the individual is expected to satisfy the incrementally higher ownership amount within seven years of the effective date of the increased requirement.
All non-employee directors were in compliance with these stock ownership requirements as of February 28, 2023. Additional information regarding beneficial ownership of Common Stock by non-employee directors is provided on pages 50-51.

REPORT OF THE AUDIT COMMITTEE
The Audit Committee reviewed Franklin Street Properties’ audited consolidated financial statements for the year ended December 31, 2022 and discussed these consolidated financial statements with management and Ernst & Young LLP, Franklin Street Properties’ independent registered public accounting firm. Management is responsible for the preparation of Franklin Street Properties’ consolidated financial statements, internal controls, and for the appropriateness of accounting principles used by Franklin Street Properties. Franklin Street Properties’ independent registered public accounting firm is responsible for performing an independent audit of Franklin Street Properties’ consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board and issuing a report on the audit of those consolidated financial statements, performing an independent audit in accordance with the standards of the Public Company Accounting Oversight Board of the effectiveness of Franklin Street Properties’ internal control over financial reporting and issuing a report on the results of such audit, and reviewing Franklin Street Properties’ unaudited interim consolidated financial statements. As appropriate, the Audit Committee reviews, evaluates and discusses with management, internal accounting, financial and auditing personnel and the independent registered public accounting firm, the following:
•
the plan for, and the independent registered public accounting firm’s report on, each audit of Franklin Street Properties’ financial statements;
​
•
Franklin Street Properties’ financial disclosure documents, including all financial statements and reports filed with the Securities and Exchange Commission or sent to stockholders;
​
•
management’s selection, application and disclosure of critical accounting policies;
​
•
changes in Franklin Street Properties’ accounting practices, principles, controls or methodologies;
​
•
significant developments or changes in accounting rules applicable to Franklin Street Properties; and
​
•
the adequacy of Franklin Street Properties’ internal controls and accounting, financial and auditing personnel.
​
The Audit Committee also received from, and discussed with, the independent registered public accounting firm various communications that the independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. Such requirements require Franklin Street Properties’ independent registered public accounting firm to discuss with the Audit Committee, among other things, the following:
•
methods to account for significant unusual transactions;
​
•
the effect of significant accounting policies in controversial or emerging areas for which there is a lack of authoritative guidance or consensus;
​
•
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
​
•
disagreements with management over the application of accounting principles, the basis for management’s accounting estimates and the disclosures in the financial statements.
​
Franklin Street Properties’ independent registered public accounting firm also provided the Audit Committee with the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. The Audit Committee discussed with the independent registered public accounting firm the matters disclosed in this letter and their independence from Franklin Street Properties.

​ | PROPOSAL TWO — RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM | ​

PROPOSAL TWO — RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Audit Committee of the Board has selected and appointed Ernst & Young LLP as our independent registered public accounting firm and to audit our consolidated financial statements for the year ending December 31, 2023. Ernst & Young LLP has audited our consolidated financial statements since the year ended December 31, 2003. Although ratification by stockholders is not required by law or by our bylaws, the Audit Committee believes that submission of its selection to stockholders is a matter of good corporate governance. Even if the appointment is ratified, the Audit Committee, in its discretion, may select a different independent registered public accounting firm at any time if the Audit Committee believes that such a change would be in the best interests of Franklin Street Properties and its stockholders. If our stockholders do not ratify the appointment Ernst & Young LLP, the Audit Committee will take that fact into consideration, together with such other factors it deems relevant, in determining its next selection of independent registered public accounting firm.
It is anticipated that a representative of Ernst & Young LLP will attend the Annual Meeting, will have an opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions.
Vote Required
A majority of all the votes cast at the Annual Meeting is required to ratify the appointment of Ernst & Young LLP. You may vote FOR or AGAINST, or abstain from ratifying the appointment of Ernst & Young LLP.

​ | PROPOSAL THREE — ADVISORY VOTE ON EXECUTIVE COMPENSATION | ​

PROPOSAL THREE — ADVISORY VOTE ON
EXECUTIVE COMPENSATION
We are providing our stockholders the opportunity to vote to approve, on an advisory, non-binding basis, the compensation of our Named Executive Officers as disclosed in this Proxy Statement in accordance with the SEC’s rules. This proposal, which is commonly referred to as “say-on-pay,” is required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which added Section 14A to the Exchange Act. Section 14A of the Exchange Act also requires that stockholders have the opportunity to cast an advisory vote with respect to whether future executive compensation advisory votes will be held every one, two or three years, which is the subject of Proposal Four. After taking into consideration the voting results of the 2017 Annual Meeting of Stockholders when our stockholders voted in favor of holding future advisory votes on the compensation of our Named Executive Officers every year, and the prior recommendation of our Board of Directors in favor of holding such advisory votes every year, we have since held advisory votes on the compensation of our Named Executive Officers every year.
Our executive compensation programs are designed to attract, motivate, and retain our executive officers, who are critical to our success. Under these programs, our Named Executive Officers are rewarded for the achievement of our financial and strategic goals and for driving corporate financial performance and stability. The “Executive Compensation” section of this Proxy Statement, including “Compensation Discussion and Analysis,” describes in detail our executive compensation program and the decisions made by the Compensation Committee and the Board with respect to the year ended December 31, 2022. Highlights of our executive compensation program include the following:
•
Our base salary amounts are generally lower than industry standard levels.
​
•
None of our executive officers has an employment agreement.
​
•
Except in the case of a change-in-control of Franklin Street Properties, we are not obligated to pay severance or other enhanced benefits to executive officers upon termination of their employment.
​
•
We do not offer stock options, restricted stock awards, deferred compensation, non-equity incentive plan compensation or perquisites, which we believe keeps our compensation simple and straightforward.
​
Our Board of Directors is asking stockholders to approve a non-binding advisory vote on the following resolution:
RESOLVED, that the compensation paid to the Company’s Named Executive Officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and any related material disclosed in the Proxy Statement, is hereby approved.
Vote Required
A majority of votes cast at the Annual Meeting is required for adoption of this proposal. You may vote FOR or AGAINST this proposal or you may abstain from voting on this proposal. If you own shares in street name, in the absence of your voting instructions, your broker, financial institution or other nominee may not vote your shares with respect to adopting this proposal in its discretion, resulting in a broker non-vote. Abstentions and broker non-votes, if any, will not be counted as votes cast and will have no effect on the result of the vote. This proposal is non-binding. The outcome of this advisory vote will not overrule any decision by the Company or the Board (or any committee thereof), create or imply any change to the duties of the Company or the Board (or any committee thereof), or create or imply any additional duties for the Company or the Board (or any committee thereof). However, our Compensation Committee and Board value the opinions expressed by our stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for our Named Executive Officers.
Recommendation
THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE APPROVAL OF THE NON-BINDING RESOLUTION APPROVING OUR EXECUTIVE COMPENSATION AS DISCLOSED IN THIS PROXY STATEMENT. PROPERLY AUTHORIZED PROXIES SOLICITED BY THE BOARD WILL BE VOTED FOR THIS PROPOSAL UNLESS INSTRUCTIONS TO THE CONTRARY ARE GIVEN.

​ | PROPOSAL FOUR — ADVISORY VOTE ON FREQUENCY OF FUTURE EXECUTIVE COMPENSATION ADVISORY VOTES | ​

PROPOSAL FOUR — ADVISORY VOTE ON FREQUENCY OF FUTURE EXECUTIVE COMPENSATION ADVISORY VOTES
In Proposal Three, we are providing our stockholders the opportunity to vote to approve, on an advisory, non-binding basis, the compensation of our Named Executive Officers. In this Proposal Four, we are asking our stockholders to cast a non-binding advisory vote regarding the frequency of future executive compensation advisory votes. Stockholders may vote for a frequency of every one, two, or three years, or may abstain.
The Board will take into consideration the outcome of this vote in making a determination about the frequency of future executive compensation advisory votes. However, because this vote is advisory and non-binding, the Board may decide that it is in the best interests of our stockholders and the Company to hold the advisory vote to approve executive compensation more or less frequently. In the future, we will propose an advisory vote on the frequency of the executive compensation advisory vote at least once every six calendar years.
After careful consideration, the Board believes that an executive compensation advisory vote should be held every year, and therefore our Board recommends that you vote for a frequency of every 1 YEAR for future executive compensation advisory votes.
The Board believes that an annual executive compensation advisory vote will facilitate more direct stockholder input regarding executive compensation. An annual executive compensation advisory vote is consistent with our practice of reviewing our executive compensation program annually. We believe an annual vote would be the best governance practice for our Company at this time.
Therefore, the Board believes that holding the executive compensation advisory vote every year is in the best interests of the Company and its stockholders and recommends voting for a frequency of every 1 YEAR.
Vote Required
You may vote 1 YEAR, 2 YEARS, 3 YEARS or you may abstain from voting on this proposal. A majority of votes cast at the Annual Meeting is required to approve one of the frequency options in this proposal. If none of the three frequency options receives the majority of the votes cast, we will consider the frequency option receiving the highest number of votes cast by stockholders to be the frequency that has been recommended by stockholders, even if the frequency selected receives less than a majority of the votes cast on the proposal.
If you own shares in street name, in the absence of your voting instructions, your broker, financial institution or other nominee may not vote your shares with respect to adopting this proposal in its discretion, resulting in a broker non-vote. Abstentions and broker non-votes, if any, will not be counted as votes cast and will have no effect on the result of the vote. This proposal is non-binding. The outcome of this advisory vote will not overrule any decision by the Company or the Board (or any committee thereof), create or imply any change to the fiduciary duties of the Company or the Board (or any committee thereof), or create or imply any additional fiduciary duties for the Company or the Board (or any committee thereof). However, our Compensation Committee and Board value the opinions expressed by our stockholders in their vote on this proposal and will consider the outcome of this frequency vote when determining the frequency of future advisory votes on executive compensation.
Recommendation
THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR 1 YEAR ON THIS PROPOSAL. PROPERLY AUTHORIZED PROXIES SOLICITED BY THE BOARD WILL BE VOTED FOR 1 YEAR ON THIS PROPOSAL UNLESS INSTRUCTIONS TO THE CONTRARY ARE GIVEN.

​ | COMPENSATION DISCUSSION AND ANALYSIS | ​

COMPENSATION DISCUSSION AND ANALYSIS
Overview
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 competitive enough 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 2022, the compensation of executives consisted of the same four components as were provided to all of our employees: (1) base salary; (2) the potential for a cash bonus; (3) matching for individual 401(k) plan contributions; and (4) the potential for a payment or payments under our change-in-control program. Although our executives are eligible to be granted awards of Common Stock under our 2002 stock incentive plan, we have not made any awards to executives under the plan since our initial listing on the American Stock Exchange (now NYSE American) in June 2005. In addition, we do not offer stock options, restricted stock awards, deferred compensation, non-equity incentive plan compensation or perquisites. None of our employees have employment agreements and, except for the Chief Executive Officer, we do not have any policies that require any of our employees to own our Common Stock. Pursuant to our Corporate Governance Guidelines, the Chief Executive Officer is required to own shares of Common Stock valued at six times his base salary.
Our executive officers consist of the Chief Executive Officer, the Chief Financial Officer, the President and Chief Investment Officer, the General Counsel, the President of FSP Property Management LLC and the Chief Operating Officer. For the fiscal year ended December 31, 2022, our Named Executive Officers were George J. Carter, our Chief Executive Officer; John G. Demeritt, our Executive Vice President, Chief Financial Officer and Treasurer; Jeffrey B. Carter, our President and Chief Investment Officer; John F. Donahue, Executive Vice President and President of FSP Property Management LLC; and Scott H. Carter, our Executive Vice President, General Counsel and Secretary.
We have reviewed our compensation policies and practices for all employees and concluded that any risks arising from our policies and programs are not reasonably likely to have a material adverse effect on Franklin Street Properties.
The objectives of our executive compensation programs
Our Compensation Committee bases our executive compensation programs on the same core objectives that guide us in establishing all of our compensation programs:
•
Compensation should promote the achievement of our business goals and maximize corporate performance and shareholder returns.
​
•
Compensation should be based on the principles of competitive and fair compensation and sustained performance.
​
•
Compensation should be based on the level of job responsibility, individual performance and corporate performance. As employees advance to higher levels within the organization, an increasing proportion of their compensation should be linked to corporate performance and enhancing shareholder value.
​
•
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.
​
•
Compensation should reward performance. Our compensation programs should deliver competitive compensation for excellent individual and corporate performance. Similarly, our compensation programs should deliver less compensation, including the possibility of no cash bonus, in the event that individual and/or corporate performance fall short of expectations.
​
•
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.
​
•
Compensation and benefit programs should be designed to attract, motivate and retain highly talented employees who are interested in building a career with us.

TABLE OF CONTENTS​​

​ | COMPENSATION DISCUSSION AND ANALYSIS | ​

What our executive compensation programs are designed to reward and how we determine the amount (and, where applicable, the formula) for each element to pay
Decisions regarding executive compensation are based on various subjective performance criteria, including corporate and individual performance.
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:
•
In 2019, the Compensation Committee retained FPL Associates L.P., an independent compensation consulting firm, to review and evaluate our executive and non-employee director compensation programs. The review and evaluation included defining a peer group of companies, benchmarking our compensation programs against the peer group, and providing market data and advice regarding executive and director compensation plan design.
​
•
Consideration of various measures of corporate performance, including without limitation, the extent to which strategic and business plan goals are met, the amount of debt repaid, gross proceeds from property dispositions, the amount (and terms) of space leased, performance of properties in our portfolio, gains or losses on property dispositions, levels of earnings, funds from operations, or FFO, dividends paid, total stockholder return and estimated net asset 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.
​
•
Consideration of individual performance. The members of the Compensation Committee meet with the Chief Executive Officer annually at the beginning of the year to discuss both individual and corporate priorities for the current year. At that same meeting, the members of the Compensation Committee meet to conduct a review of the Chief Executive Officer’s performance over the past year based on various subjective performance criteria, including his contributions to individual and corporate priorities, his contribution to corporate performance, the degree to which teamwork and corporate 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 Committee receive a performance assessment and compensation recommendation from the Chief Executive Officer. In reviewing and approving the compensation for each of the other Named Executive Officers, the Compensation Committee is not required to give specific weight to any particular criterion or performance metric. The Compensation Committee considers the performance assessment and compensation recommendation from the Chief Executive Officer and also exercises its own judgment based on various subjective performance criteria, including contributions to corporate performance, the degree to which teamwork and corporate values were fostered and other leadership accomplishments.
​
•
Comparison of our executive compensation programs as a whole and also a comparison of total executive compensation for each individual with the compensation practices of other companies in the real estate industry. Historically, the Compensation Committee has used the National Association of Real Estate Investment Trusts (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 general compensation guidelines. Our Compensation Committee does not apply a formula or assign the survey data relative weight. Instead, it makes a subjective determination for that individual after considering such results collectively.
​
•
Our stockholders approved each of the say-on-pay proposals in 2019, 2020 and 2021 by over 95% of votes cast. The Compensation Committee considered this support level in its determination to maintain similar compensation policies and elements of compensation in 2022.
​
Each element of compensation and why we choose to pay each element
(a)
Base Salary
​
Executive officers 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.

TABLE OF CONTENTS

​ | COMPENSATION DISCUSSION AND ANALYSIS | ​

(b)
Cash Bonus
​
Executive officers are eligible for a cash bonus based on various subjective performance criteria, including corporate and individual performance. 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 corporate and individual performance. We also believe that the payment of a competitive cash bonus is consistent with the compensation practices of other comparable companies.
(c)
401(k) Matching
​
Executive officers are eligible to participate in our 401(k) plan. We offer all employees a 401(k) plan that, in 2022, allowed for salary deferrals of up to $20,500 per year (indexed for inflation), or up to $27,000 per year including catch-up provisions for individuals aged 50 or older. We matched up to 3% of an employee’s compensation (up to a compensation cap of $200,000) for plan year 2022 and will match up to 3% of employee compensation (up to a compensation cap of $200,000) for plan year 2023. Employees make their 401(k) contributions through payroll deductions with pretax dollars. All employees are eligible to participate in the plan immediately upon hiring. 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 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.
(d)
Change-in-Control Program
​
Except in the case of a change-in-control of Franklin Street Properties, 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 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 Franklin Street Properties. 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 Franklin Street Properties 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:
•
The program consists of two components: a fixed payment pursuant to a retention agreement between the employee and Franklin Street Properties and the potential for an additional discretionary payment pursuant to a discretionary plan.
​
•
The triggering event for both components is a change-in-control of Franklin Street Properties. A change-in-control of Franklin Street Properties, as defined in the plan, generally refers to a change in ownership or effective control of Franklin Street Properties or a change in ownership of a substantial portion of the assets of Franklin Street Properties.
​
•
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 would receive payments equal to three years of their base salaries plus a bonus opportunity payment equal to three years of their base salaries. 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. Payments under the retention agreements are subject to a possible reduction, if any, after the tax consequences of the payment are determined.
​
•
Under the discretionary plan component of the program, immediately prior to the closing of the change-in-control, our Board of Directors may (but is not obligated to) establish a discretionary pool of funds equal to 1% of the market capitalization of Franklin Street Properties 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. Our Board of Directors would have complete discretion to award all, a portion
​
FRANKLIN STREET PROPERTIES CORP. | 2023 PROXY STATEMENT 41

TABLE OF CONTENTS​

​ | COMPENSATION DISCUSSION AND ANALYSIS | ​

or none of the discretionary plan pool of funds to any employees of Franklin Street Properties, including the executive officers. Payments under the discretionary plan component are subject to a possible reduction, if any, after the tax consequences of the payment are determined.
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.
(e)
Awards of Common Stock under our 2002 Stock Incentive Plan
​
Executive officers are eligible for awards of Common Stock under our 2002 stock incentive plan. The 2002 stock incentive plan permits our Board of Directors to award up to 2,000,000 shares of our Common Stock to eligible participants. Prior to our listing on the American Stock Exchange (now the NYSE American) in June 2005, our employees were not able to purchase our Common Stock, and we determined that it was necessary and appropriate to be able to compensate our employees with stock awards as a means of attracting, retaining and motivating key personnel and to align the interests of management and all personnel with those of our stockholders. All of our employees, officers and directors are eligible to participate in the plan. There have been no awards of Common Stock to executive officers under the 2002 stock incentive plan since we started listing our Common Stock on a stock exchange in June 2005, as employees are now able to purchase Common Stock in the open market. As of February 28, 2023, 1,696,687 shares of our Common Stock were available under the plan. Although we have not made any awards to executive officers under the 2002 stock incentive plan since 2005, we may determine in the future to grant stock awards to executive officers under the 2002 stock incentive plan or a new stock plan in order to attract, retain, or motivate our executives.
How each element and our decisions regarding that element fit into our overall compensation objectives and affect decisions regarding other elements
Overview
The Compensation Committee recognizes that broad macroeconomic factors negatively impacted both the business operations and the stock performance of many office REITs during 2022, including FSP. Within that relative context, the Compensation Committee believes that our executive officers worked diligently during 2022 to try to increase shareholder value through the sale of select properties, and met the goals of using disposition proceeds primarily for the repayment of debt, and leasing vacant space. More specifically, during 2022, our executive officers managed the disposition of three properties for aggregate gross proceeds of approximately $130 million and the repayment of approximately $152 million of debt. During 2022, we also leased approximately 435,000 square feet of space.
(a)
Base Salary
​
In reviewing base salaries for 2022, the members of the Compensation Committee applied the principles described above under “What our executive compensation programs are designed to reward and how we determine 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 annualized base salary increases of approximately 3% for each of the executive officers other than the Chief Executive Officer. The above-described annualized base salary increases were effective on January 17, 2022. With respect to the Chief Executive Officer, for the reasons discussed above, the Compensation Committee did not make a recommendation for an increase in base salary to our Board of Directors. The last time that our Chief Executive Officer accepted a base salary increase was in February 2015. Our base salary amounts are generally lower than industry standard levels. Accordingly, compensation of these positions will be weighted proportionately greater towards year-end bonus amounts based upon corporate and individual performance.
(b)
Cash Bonus
​
In awarding cash bonuses for 2022, the members of the Compensation Committee applied the principles described above under “What our executive compensation programs are designed to reward and how we determine the
42 FRANKLIN STREET PROPERTIES CORP. | 2023 PROXY STATEMENT

​ | COMPENSATION DISCUSSION AND ANALYSIS | ​

amount (and, where applicable, the formula) for each element to pay.” Based upon the recommendation of the Chief Executive Officer, the Compensation Committee approved cash bonuses for each of the executive officers other than the Chief Executive Officer in the amounts recommended by the Chief Executive Officer. In making his recommendations, the Chief Executive Officer noted, and the Compensation Committee made a subjective determination, that each officer’s area of responsibility and accountability (i.e., business unit) contributed to the Company’s performance during 2022, 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 Franklin Street Properties and of great value to Franklin Street Properties and firmly committed to doing what is in the best interests of our stockholders.
The cash bonus amounts paid to executive officers other than the Chief Executive Officer for 2022 are approximately 17% lower than those paid for 2021. The Chief Executive Officer, in consultation with the Compensation Committee, recommended lower cash bonus amounts due to a variety of subjective factors, including without limitation, the price of our Common Stock, the level of property dispositions, the amount of debt repaid, and leasing during 2022 compared to 2021. While the Chief Executive Officer and the Compensation Committee recognize that broad macroeconomic factors negatively impacted both the business operations and the stock performance of many office REITs during 2022, they determined that a downward adjustment to the cash bonus amounts for each of the executive officers other than the Chief Executive Officer was appropriate in light of the various adverse impacts that all FSP stakeholders experienced during 2022. The Compensation Committee believes that the reduced cash bonus amounts are 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 as the Company.
The Compensation Committee also reviewed and evaluated the performance of the Chief Executive Officer during 2022 by applying the principles described above under “What our executive compensation programs are designed to reward and how we determine the amount (and, where applicable, the formula) for each element to pay.” Within the relative context of the broad macroeconomic factors that negatively impacted both the business operations and stock performance of many office REITS during 2022, including FSP, the Compensation Committee made a subjective determination that the combined business units performed well under the leadership, focus and discipline of the Chief Executive Officer. However, for the reasons discussed above, the Compensation Committee did not make a recommendation for a bonus for our Chief Executive Officer.
(c)
401(k) Matching
​
There were no proposals made to modify our 401(k) plan program in 2022.
(d)
Change-in-Control Program
​
Because we determined that our change-in-control program continues to satisfy its original intended purpose, there were no proposals made to modify the program in 2022.
(e)
Awards of Common Stock under our 2002 Stock Incentive Plan
​
Because we determined that we were able to adequately compensate the executive officers who make up the corporate management team with salary and cash bonuses in 2022, no Common Stock awards were made to executive officers in 2022.

​ | POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL | ​

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 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 we choose to pay each element — (d) Change-in-Control Program.”
Assuming that the closing of a change-in-control occurred on December 31, 2022, 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 | ​ | ​ | Potential Payment due under the Retention Agreement | ​
George J. Carter, Chief Executive Officer (PEO) | ​ | ​ | ​ | ​ | N/A(1) | ​ | ​
John G. Demeritt, Executive Vice President, Chief Financial Officer and Treasurer (PFO) | ​ | ​ | ​ | $ | 1,756,872(2) | ​ | ​
Jeffrey B. Carter, President and Chief Investment Officer | ​ | ​ | ​ | $ | 1,759,735(2) | ​ | ​
Scott H. Carter, Executive Vice President, General Counsel and Secretary | ​ | ​ | ​ | $ | 1,528,140(2) | ​ | ​
John F. Donahue, Executive Vice President and President of FSP Property Management LLC | ​ | ​ | ​ | $ | 1,484,209(2) | ​ | ​
TOTAL | ​ | ​ | ​ | $ | 6,528,956 | ​ | ​

​
NOTES
(1)
George J. Carter has voluntarily elected not to participate in the retention agreement component of our change-in-control program.
​
(2)
These are lump-sum payments equal to three years of base salaries plus a bonus opportunity payment equal to three years of base salaries. The payment amounts are subject to a possible reduction, if any, after the tax consequences are determined.
​
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 31, 2022, there were 103,235,914 shares of our Common Stock outstanding, and on December 30, 2022 (the last trading day of 2022), the closing price per share of our Common Stock was $2.73. Accordingly, on December 31, 2022, our market capitalization was $281,834,045, and 1% of our market capitalization equaled $2,819,340. Because 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 at December 31, 2022 exceeded 1% of our market capitalization at December 31, 2022, no funds would have been available for our Board of Directors to award under the discretionary plan component of our change-in-control program at December 31, 2022. 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.

For all years, Mr. George J. Carter served as our PEO and Mr. John G. Demeritt, Mr. Jeffrey B. Carter, Mr. Scott H. Carter and Mr. John F. Donahue served as the Other NEOs.
​
(2)
For all years, the peer group is the FTSE NAREIT Equity Office Index.
​
(3)
While our Compensation Committee employs a subjective approach to the consideration of various measures of corporate performance, for 2022, the Company identified the amount of debt repaid as the most important financial performance measure used to link the compensation actually paid to the PEO and the Other NEOs for 2022 to the Company’s performance. The amount of debt repaid is calculated from the Company’s Consolidated Statements of Cash Flows by adding “Repayment of term loans payable” to “Repayments of bank note payable”.
​
(4)
The following table lists the seven most important financial performance measures used by the Company to link compensation actually paid to the PEO and the Other NEOs in 2022 to the Company’s performance:
​

​ | Debt repaid | ​
​ | Gross proceeds from property dispositions | ​
​ | Amount (and terms) of space leased | ​
​ | Funds from operations (FFO) | ​
​ | Dividends paid | ​
​ | Total stockholder return | ​
​ | Estimated net asset value | ​

​
(5)
In the “Compensation Discussion and Analysis” section of this Proxy Statement, we provide greater detail on the elements of our executive compensation program and our compensation philosophy. We believe the Company’s executive compensation program and the executive compensation decisions included in the 2022 Summary Compensation Table and related disclosures appropriately reward our PEO and the Other NEOs for Company and individual performance, assist the Company in retaining our senior leadership team and support long-term value creation for our stockholders.

PAY RATIO DISCLOSURE
Pursuant to applicable SEC rules, presented below is a reasonable estimate of the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of our other employees.
We determined our median employee based on annual total compensation, consisting of salary, bonus and 401(k) match, actually paid for 2022 performance(1) to each of our 27 employees (excluding the Chief Executive Officer) as of December 31, 2022. The annual total compensation of our median employee (excluding the Chief Executive Officer) for 2022(1) was $205,593. As disclosed in the Summary Compensation Table appearing on page 44, our Chief Executive Officer’s annual total compensation for 2022 was $306,000. Based on the foregoing, our estimate of the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of all other employees was approximately 1.49 to 1.

TRANSACTIONS WITH RELATED PERSONS
Related Person Transaction Policy
Our Board of Directors adopted written policies and procedures for the review of any transaction, arrangement or relationship in which Franklin Street Properties 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 General 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 of Directors. 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:
•
the related person’s interest in the related person transaction;
​
•
the approximate dollar value of the amount involved in the related person transaction;
​
•
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;
​
•
whether the transaction was undertaken in the ordinary course of our business;
​
•
whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;
​
•
the purpose of, and the potential benefits to us of, the transaction; and
​
•
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.
​
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.
No member of the Audit Committee shall participate in any review or approval (or ratification) of any related person transaction in which such member is the related person, any immediate family member of such member is the related person, or any significant shareholder with which such member is affiliated is the related person.
In addition to the transactions that are excluded by the instructions to the Securities and Exchange Commission’s related person transaction disclosure rule, our Board of Directors 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:
•
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;
​
•
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;

OTHER INFORMATION
MATTERS TO BE CONSIDERED AT THE MEETING
​
The Board of Directors does not know of any other matters that may come before the Annual Meeting. However, if any other matters are properly presented at the Annual Meeting, it is the intention of the persons named in the accompanying proxy to vote, or otherwise act, in accordance with their discretion on such matters.
SOLICITATION OF PROXIES
​
All costs of solicitation of proxies will be borne by Franklin Street Properties. In addition to solicitations by mail or via the Internet, our 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, we 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 our proxy statement and form of proxy for the 2024 Annual Meeting of Stockholders must be received by Franklin Street Properties at its principal office not later than December 1, 2023. In addition, according to our current bylaws, any stockholder proposal intended to be presented at an annual meeting, including nominations for election to the Board, but not considered for inclusion in our proxy statement relating to such meeting, must be received at Franklin Street Properties’ principal office not earlier than the 150th day nor later than 5:00 p.m., Eastern Time, on the 120th day prior to the first anniversary of the mailing date of the preceding year’s proxy materials. For the 2024 Annual Meeting of Stockholders, that means that a stockholder must deliver proper notice of a proposed nominee or action that is proposed to be presented at the 2024 Annual Meeting of Stockholders but not be included in the proxy statement for such meeting to the Secretary of Franklin Street Properties between November 1, 2023 and December 1, 2023. In addition to the timing of the delivery of the notice, our bylaws include specific information that must be provided (including the information required by Rule 14a-19 under the Exchange Act) and procedures that must be followed to submit a proposal.
IMPORTANT NOTICE REGARDING DELIVERY OF SECURITY HOLDER DOCUMENTS
​
The Company may participate in the practice of “householding” proxy statements, annual reports and Notices of Internet Availability of proxy materials, meaning that the Company delivers a single document 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 any of the foregoing documents to a stockholder if a stockholder writes to or calls the Company at the following address or phone number: Franklin Street Properties Corp., 401 Edgewater Place, Suite 200, Wakefield, Massachusetts 01880, (877) 686-9496. If a stockholder wants to receive separate copies of the annual report and proxy statement or Notice of Internet Availability of proxy materials 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.
