Under the Company’s Restated Articles of Incorporation, the holders of the Company’s Class A Common Stock are entitled to one vote for each share held.

Shares subject to such “brokernon-votes” will are considered present for purposes of establishing a quorum but not be treated as shares entitled to vote on the matters to which they relate and therefore will be treated as not present at the meeting for those purposes, but otherwise will have no effectany impact on the outcome of the voting on such matters.proposal. Accordingly, shareholders are encouraged to provide instructions to their brokers regarding the voting of their shares.

PROPOSAL NO. 1

APPROVAL OF AN AMENDMENT TO THE BYLAWS FIXING THE SIZE OF THE BOARD OF DIRECTORS AT NOT LESS THAN THREE NOR MORE THAN SEVEN.

The Board of Directors (the “Board”) is proposing an amendment to the Company’s Bylaws fixing the size of the Board at not less than three nor more than seven members. Presently, the Bylaws provide that the Board shall be not less than five nor more than nine members. With the sale of the Company’s East Providence petroleum storage terminal, the Board concluded that the time and effort required to discharge its responsibilities no longer required a five person Board and that three members would be more than adequate given that most of the Company’s revenue and expense will be related to its leasing operations in the Capital Center and adjacent Company property in Providence, Rhode Island. Mr. and Mrs. Eder, holders of 52.3% of the Company’s outstanding Class A common stock, have informed the Board that they intend to vote in favor of this amendment.

If this amendment is approved by our shareholders, it will become effective immediately and only three directors will be elected. If this amendment is not approved by the Company’s shareholders, the Bylaws will not be amended and there will be one vacancy on the Board due to Mr. Turcotte’s resignation. Mr. Rosen will continue to serve until his successor is elected and qualified.

PROPOSAL NO. 2

APPROVAL OF AN AMENDMENT TO THE BYLAWS FIXING THE DATE FOR THE ANNUAL MEETING OF THE SHAREHOLDERS AS THE LAST TUESDAY IN APRIL AND FIXING THE DATES FOR QUARTERLY MEETINGS OF THE BOARD OF DIRECTORS AS THE LAST TUESDAY IN THE MONTHS OF JULY, OCTOBER, JANUARY AND APRIL OF EACH YEAR.

The Board is proposing an amendment to the Company’s Bylaws to:

The Bylaws now provide that the date of the annual shareholders meeting will be the Tuesday next preceding the last Wednesday in April of each year. Because this date can vary from year to year, the Board concluded that for planning purposes it would be better if the annual meeting was held during the last week in April on a consistent basis.

2

As to Director meetings, the current Bylaws require that the meetings be held on the Tuesday next preceding the last Wednesday in the months of July, October, January and April. As the Board generally meets immediately following the annual meeting of shareholders to elect officers, the Board determined that it was prudent to avoid the necessity of an additional Board meeting and that consistency in timing of Board meetings would assist Board members in their planning. Accordingly, the Board is proposing amendments to the Bylaws to provide that Board meetings will be held on the last Tuesday in each of July, October, January and April. In addition, the amendments would allow the Board to select a different date for the annual shareholders meeting and any quarterly Board meeting. The Board believes that it is desirable to provide the Board with flexibility in establishing meeting dates.

If these amendments are approved by our shareholders, they will become effective immediately. If these amendments are not approved, the annual shareholders meeting and quarterly Board meetings will continue to be held on the Tuesday next preceding the last Wednesday (1) of April in the case of the annual shareholders meeting and (2) July, October, January and April in the case of quarterly director meetings.

PROPOSAL NO. 3

ELECTION OF DIRECTORS

At the annual meeting, fivethree directors are to be elected to hold office until the next annual meeting and until their respective successors are elected and qualified. The proxies named in the accompanying proxy who have been designated by the Board, of Directors, intend to vote, unless otherwise instructed, for the election to the Board of

Directors of the persons named below who are now directors of the Company. The Board has fixed the number of directors at three, conditioned on the approval of Proposal No. 1. Certain information concerning such nominees is set forth below:

Mr. Eder is also a director of Providence and Worcester Railroad Company.

3

The Board of Directors has reviewed the relationship that each director, including each director who served during 2016, and nominee for director, which includes each of the nominees standing for election at the 20162017 annual meeting, and has with the Company and determined that all such directors and nominees for director, other than Robert H. Eder, and Todd D. Turcotte, are independent as defined under the NASDAQ listing standards.

The Board of Directors does not have a policy with respect to diversity and does not specifically consider issues of diversity, such as gender, race, origin, or sex when determining whether to nominate a person to be a director of the Company. When considering whether directors and nominees have the experience, qualifications, attributes and skills, taken as a whole, to enable the Board of Directors to satisfy its oversight responsibilities effectively in light of the Company’s business and structure, the Board of Directors focuses primarily on each director’s and nominee’s individual background and experience as it relates to the Company’s business. Historically, when vacancies have occurred, each director has been requested to suggest potential nominees and each potential nominee is vetted with the entire Board.

In particular, with regard to Mr. Corso, the Board of Directors considered his training, work experience as a partner of Ernst & Young and his service as a controller of a publicly-held corporation which activities qualify him as a financial expert. With regard to Mr. Eder, the Board of Directors considered that he is the Company’s founder, he has been actively involved with the Company or its predecessors since 1966 and is the majority shareholder. With regard to Mr. Rosen, the Board of Directors considered his history as the owner of his own business and his substantial community contacts which the Board believes assists in assessing the Company’s role in the community and furthering its community contacts and relationships. Likewise, with regard to Mr. Triedman, the Board of Directors considered his experience as a business owner and contacts within the community in which the Company operates. With regard to Mr. Turcotte, the Board of Directors considered his strong background in engineering and insights as Vice President of the Company and President of Capital Terminal Company.

Communications with the Board of Directors

The Board of Directors has established a process for shareholders to communicate with members of the board.Board. If you have any concern, question or complaint regarding our compliance with any policy or law, or would

2

otherwise like to contact the Board, of Directors, you may reach the Company’s Board of Directorsour directors by writing directly to those individuals c/o Capital Properties, Inc., 100 Dexter Road, East Providence, Rhode Island 02914.

Any inquiries received will not be screened by the Company and will be forwarded directly to the director to which such inquiry is addressed, unless it is believed that a particular inquiry may pose a security risk. The Board of Directors sits as a committee of the whole to address any inquiries made by shareholders.

Board Leadership Structure

Robert H. Eder serves as both the President and the Chairman of the Board of the Company.Company and is the Company’s chief executive officer. The Board of Directors believes that the Company’s Chief Executive Officerchief executive officer is best situated to serve as Chairman because he is the director most familiar with the Company’s business and industry, and most capable of effectively identifying strategic priorities and leading the discussion and execution of strategy. Independent directors and management have different perspectives and roles in strategy development. The Company’s independent directors bring experience, oversight and expertise from outside the

4

Company and industry, while the Chief Executive Officerchief executive officer brings Company-specific experience and expertise. The Board of Directors believes that the combined role of Chairman and Chief Executive Officerchief executive officer promotes strategy development and execution and facilitates information flow between management and the Board, which are essential to effective governance.

One of the key responsibilities of the Board of Directors is to develop strategic direction and hold management accountable for the execution of strategy once it is developed. The Board of Directors believes the combined role of Chairman and Chief Executive Officerchief executive officer is in the best interest of shareholders because it provides the appropriate balance between strategy, development and independent oversight of management.

Committees of the Board of Directors

The Board of Directors has an Audit Committee and a Compensation Committee, both of which are currently comprised of Messrs. Corso Rosen and Triedman, and Harris N. Rosen, each of whom is independent as defined under applicable rules of the Securities and Exchange Commission (“SEC”) and NASDAQ listing requirements.¹ Each of the Audit and Compensation Committees has a written charter approved by the Board of Directors.Board. Mr. Corso chairs the Audit Committee and Mr. Rosen chairs the Compensation Committee.

The Audit Committee is responsible for overseeing the establishment and maintenance of an effective financial control environment for the Company, for establishing procedures for evaluating the system of internal accounting control and for evaluating audit performance.

The Board of Directors has determined that the members of the Audit Committee satisfy the financial literacy requirements of the NASDAQ listing standards and are independent as defined under the NASDAQ listing requirements and applicable rules of the SEC. Additionally, the Board of Directors has determined that Mr. Corso qualifies as an “audit committee financial expert” as defined by the SEC rules. A copy of the current Audit Committee Charter is attached as Appendix A to this Proxy Statement.

The Compensation Committee assists the Board of Directors in discharging the Board’s responsibilities relating to director and executive compensation. The Compensation Committee’s responsibilities include establishing and reviewing the Company’s executive and director compensation philosophy, strategies, plans and policies, and evaluating the performance and determining the compensation of the Chairman and Chief Executive Officer (“CEO”) of the Company and advising and assisting the CEO in formulating and implementing programs to facilitate the selection and development of other key managers. The Compensation Committee also reviews and

approves the compensation of other executive officers of the Company.

5

The Company does not maintain a nominating committee or a committee performing a similar function due to the fact that Mr. Eder owns a controlling interest in the Company. The Board of Directors sits as a committee of the whole to consider any recommendations made by shareholders and/or other directors of persons to be directors of the Company. In determining whether to nominate any such person for election by the shareholders, the Board of Directors considers the experience of such person as it relates to the business of the Company, together with such person’s age, reputation and ability to carry out the requirements to serve as a director of the Company. The Board of Directors does not have a policy with respect to diversity and does not specifically consider issues of diversity, such as gender, race, origin or sex when determining whether to nominate a person to be a director of the Company.

During the fiscal year ended December 31, 2015,2016, the Board of Directors held fourseven meetings, the Audit Committee held fivesix meetings and the Compensation Committee held one meeting. All directors attended every meeting of the Board of Directors and meetings of committees on which such director serves, except that one director was unable toMr. Triedman who did not attend one Board of Directors meeting and one Audit Committee meeting. The independent directors held one meeting. The Board of Directors has adopted a policy that requires members of the Board of Directors to make every effort to attend each annual shareholders meeting. All then current members of the Board of Directors attended the 20152016 annual shareholders meeting.

Risk Management

The Board of Directors has an active role, as a whole and also at the Audit Committee level, in overseeing management of the Company’s risks. The Board of Directors regularly meets with management and reviews information regarding the Company’s overall risks. The Audit Committee oversees management of financial and operational risks and oversees management of risks associated with regulatory, environmental, health and safety. The Board of Directors does not believe there is any high degree of risk associated with its compensation practices as the Company does not provide for any incentive-based compensation other than infrequent cash bonuses which have only been paid in connection with extraordinary events. Furthermore, salary increases for employees of the Company are based primarily on increases in the cost of living.

Compensation of Directors

The Board, of Directors, upon recommendation of the Compensation Committee, is responsible for determining compensation of the directors. Directors, other than directors who are employed by the Company, received a fee for attendance at each meeting of the Board, of Directors, together with related transportation and living expenses.

The maximum fees payable for attendance at Board and committee meetings occurring on the same day is $1,500.

Based solely on a review of the copies of forms furnished to the Company and written representations from the executive officers and directors of the Company, the Company believes that, during 2015,2016, its executive officers, directors and greater than ten percent beneficial owners complied with all applicable Section 16(a) requirements.

TRANSACTIONS WITH MANAGEMENT

Potential conflicts of interest and related party transactions are referred by the Board of Directors to the Audit Committee for review and approval. In reviewing and evaluating potential conflicts of interest and related party transactions, the Audit Committee uses applicable SEC rules as a guide.

During 2010, the Compensation Committee engaged Effective Pay Practices of Gloucester, Massachusetts to update its prior study on executive compensation. After receipt of the study and review of its recommendations, the Compensation Committee approved executive compensation for each of the Chairman, President and Chief Executive Officer (the “Chairman”); the Treasurer; and the Vice President and President of Capital Terminal Company effective January 1, 2011 as follows:

The Committee also approved a further increase effective January 1, 2012 in the Treasurer’s compensation to $192,500 and toin the Vice President and President of Capital Terminal Company’s compensation to $182,500.

PROPOSAL NO. 4

ADVISORY(NON-BINDING) VOTE ON EXECUTIVE COMPENSATION

In accordance with Dodd-Frank Wall Street Reform and Consumer Protections Action of 2010 (Dodd-Frank Act), the Company presents the following proposal which gives shareholders the opportunity to endorse or to not endorse the Company’s compensation policies and procedures for its named executive officers, commonly known as a“say-on-pay” proposal.

“RESOLVED, to approve the Company’s executive compensation, as described in the “Executive Compensation” section and tabular disclosure regarding named executive officer compensation (together with the accompanying narrative discussion) in this Proxy Statement.”

We believe that our compensation policies and procedures, which are described more fully in the tables and narrative in the “Executive Compensation” section of this Proxy Statement, are strongly aligned with the interest of shareholders. The Company’s Board believes that the Company’s compensation policies and procedure do not create undue risk nor are they excessive in an amount or nature. Absent a compensation study by outside consultants which is approved in whole or in part by the Compensation Committee and where required, the Board, salary increases are based solely on cost of living increases which result in minimal increase each year and the Company generally does not pay any bonuses to its executives except in unique circumstances. The Board recently authorized a bonus to the Company’s Vice President and President of Capital Terminal Company for his exceptional work in connection with the sale of the Company petroleum storage terminal and related properties, which was paid in February 2017 and is not reflected in the annual compensation table for 2016.

Approval of this proposal will require the affirmative vote of a majority of Class A Common Stock. While the Company’s Board will consider carefully the results of shareholder voting upon this proposal, the outcome of this vote will not be binding on or overrule any decisions by the Board and will not create or imply any additional fiduciary duty on the part of the Board.

AUDIT COMMITTEE REPORT

Management is responsible for the Company’s internal controls and financial reporting process. The independent registered public accountants are responsible for performing an audit of the Company’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and to issue a report thereon. The Audit Committee’s responsibility is to monitor and oversee these processes.

The Audit Committee has sole authority to select, evaluate and when appropriate, to replace the Company’s independent registered public accountants. Additionally, and as appropriate, the Audit Committee reviews and evaluates, and discusses and consults with the Company’s management and independent registered public accountants regarding the scope of the audit plan, the results of the audit, the Company’s financial statement disclosure documents, the adequacy and effectiveness of the Company’s accounting and financial controls and changes in accounting principles.

7

InFor the fiscal year ended December 31, 2015 and until October 14, 2016, LGC&D LLP (“LGC&D”) served as the Company’s independent registered public accountants. On October 14, 2016 LGC&D resigned the engagement due to the fact that certain of its partners had joined another firm. LGC&D’s audit reports on the Company’s financial statements as of and for the fiscal years ended December 31, 2014 and 2015 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or the Company’s accounting principles. During the Company’s last two most recent fiscal years ended December 31, 2014 and 2015 and for the subsequent interim period through October 14, 2016 (the date of resignation), there were no disagreements with LGC&D on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements if not resolved to the satisfaction to LGC&D would have caused it to make reference to the subject matter of the disagreements in connection with these responsibilities,its reports and there were no reportable events described in Item 304(a)(1)(v) of RegulationS-K.

On October 18, 2016, the Audit Committee accepted the resignation of LGC&D and approved the appointment of Stowe & Degon, LLC (“Stowe & Degon”) as the Company’s independent registered public accountants for the remainder of fiscal year 2016 and to audit its financial statements for the fiscal year ending December 31, 2016. During the Company’s last two fiscal years ended December 31, 2014 and 2015 and for the subsequent interim period prior to Stowe & Degon’s engagement, the Company did not consult Stowe & Degon or any other firm with respect to any matters or events referred to in Item 304(a)(2)(i) and (ii) of RegulationS-K. The Company provided LGC&D and Stowe & Degon with a copy of the foregoing disclosure.

The Audit Committee reviewed and discussed the audited consolidated financial statements with management and the Company’s independent registered public accountants, LGC&D LLP.Stowe & Degon. The Audit Committee also discussed with such firm the matters required by the PCAOB Auditing Standard No. 16. The Audit Committee received from LGC&D LLPStowe & Degon written disclosures and the letter regarding its independence as required by Independence Standards Board Standard No. 1,No.1, wherein LGC&D LLPStowe & Degon confirmed its independence within the meaning of the SEC and Independence Standards Board Rules and disclosed the fees charged for professional services in the fiscal year ended December 31, 2015.2016. The Audit Committee discussed this information with LGC&D LLPStowe & Degon and also considered the

12

compatibility ofnon-audit services provided by such firm with its independence. Based on the review of the audited consolidated financial statements and these various discussions, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in the Company’s Annual Report on Form10-K, to be filed with the SEC.

Audit Committee: Alfred J. Corso (Chair), Harris N. Rosen and Steven G. Triedman.

INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS

The Audit Committee of the Board of Directors has sole authority to engage, manage and discharge the Company’s independent registered public accountants. The Committee engaged LGC&D LLP as independent registered public accountants of the accounts of the Company for the year 2015 and for that part of fiscal year 2016 occurring on and prior to October 14, 2016 and Stowe & Degon for the balance fiscal year 2016. The Company has recently been advised by LGC&D LLPStowe & Degon that it has no direct financial interest or any material indirect financial interest in the Company, nor have theyhas that firm had any connection during the past three years with the Company in the capacity of promoter, underwriter, voting trustee, director, officer or employee.

It is expected that a representative of LGC&D LLPStowe & Degon will be present at the annual meeting and will be provided the opportunity to make a statement if he or she so desires and that such representative will be available to respond to appropriate questions.

Audit andNon-Audit Fees:

The aggregate fees for professional services rendered for the Company by LGC&D LLP for fiscal year ended December 31, 2015 and for LGC&D and Stowe & Degon for the fiscal year ended December 31, 2016 are set forth below.

Audit Feesfor fiscal years ended December 31, 2015 and 2014 are set forth below.

Audit Fees for fiscal years ended December 31, 2015 and 20142016 were for professional services rendered for the audits of the Company’s annual financial statements and the reviews of interim financial statements included in the Company’s Quarterly Reports on Form10-Q, consents and other assistance required to complete the year endyear-end audit of the Company’s financial statements.

Audit-Related Feesfor the fiscal years ended December 31, 2015 and 2014:2016: there were no audit-related fees.

13

Tax Feesfor the fiscal years ended December 31, 2015 and 20142016 were for services related to tax return preparation. All of these fees were paid to LGC&D.

All Other Feesfor the fiscal years ended December 31, 2015 and 2014:2016: there were no other fees.

For fiscal 2016, the aggregate fees for professional services rendered by LGC&D and Stowe & Degon were $38,000 and $52,000, respectively.

8

The Audit Committee (or in the case of minor matters, the Chairman)pre-approves all audit andnon-audit services provided by the independent auditors prior to the engagement of the independent auditors with respect to such services.

The Audit Committee has determined that the provision of such services was compatible with maintaining LGC&D’s independence and is compatible with maintaining LGC&D LLP’sStowe & Degon’s independence.

PROPOSAL NO. 2

APPROVAL OF AN AMENDMENT TO THE BYLAWS OF THE COMPANY DESIGNATING THE STATE OF RHODE ISLAND AND PROVIDENCE PLANTATIONS AS THE EXCLUSIVE FORUM FOR CERTAIN LEGAL ACTIONS

The Board of Directors is proposing an amendment to the Bylaws of the Company (“Bylaws”) to add a new Section 5 to Article VI designating courts of the State of Rhode Island and Providence Plantations as the sole and exclusive forum for certain legal actions. The proposed amendment would designate (i) any derivative action brought on behalf of the Company, and (ii) any action brought by a shareholder against the Company or any of our directors, officers, or other employees alleging a violation of the State of Rhode Island Business Corporation Act, the Company’s legislative charter, or Bylaws, a breach of fiduciary duties, or a violation asserting a claim governed by the internal affairs doctrine. This would not include actions in which the courts of the State of Rhode Island conclude that an indispensable party is not subject to the jurisdiction of the State of Rhode Island courts and can be subject to the jurisdiction of another court within the United States.

This amendment is intended to avoid subjecting the Company to multiple lawsuits in multiple jurisdictions on matters relating to the corporate law of the State of Rhode Island, our state of incorporation. The ability to require such actions to be brought in a single forum provides numerous benefits to the Company and our shareholders including the avoidance of costly and duplicative litigation, reducing the risk and cost of multi-jurisdictional disputes, and discouraging forum shopping.

The Board of Directors is aware that certain proxy advisors, and even some institutional shareholders, take the view that they will not support an exclusive forum clause until the company requesting it can show it already has suffered material harm as a result of multiple shareholder suits filed in different jurisdictions regarding the same matter. The Board of Directors believes that it is more prudent and in the best interest of shareholders to take preventive measures before the Company and the interests of most of its shareholders are materially harmed by the increasing practice of the plaintiff’s bar to file claims in multiple jurisdictions. It is important to note that this action by the Board of Directors is not being taken in reaction to any specific litigation confronting the Company; rather, this action is being taken on a prospective basis to prevent potential future harm to the Company and its shareholders.

If this amendment is approved by our shareholders, it will become effective immediately upon amending the Bylaws of the Company and the filing of any required state or federal certifications, which we intend to do promptly following action by the shareholders at the Annual Meeting. If this amendment is not approved by the Company’s shareholders, the Bylaws will not be amended. The complete text of the proposed amendment is set forth in Appendix C.
