<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Under the 2021 Plan, employees, <FONT STYLE="white-space:nowrap">non-employee</FONT> directors and consultants of Boston Properties, Inc. and
its subsidiaries, including Boston Properties Limited Partnership, are eligible for grants and other equity-based awards. The list of available awards under the 2021 Plan includes awards that are valued in whole or in part by reference to, or are
otherwise based on, shares of Common Stock of Boston Properties, Inc., including, without limitation, convertible preferred stock, convertible debentures, other exchangeable or redeemable securities or equity interests and awards valued by reference
to book value, fair value or subsidiary performance (&#147;Other Awards&#148;). Such Other Awards may be issued either alone or in addition to other awards granted under the 2021 Plan. The 2021 Plan administrator has the authority to determine the
eligible recipients to whom, and the time or times at which, Other Awards shall be made; the number of shares or units to be awarded; the price, if any, to be paid by the participant for the acquisition of Other Awards; and the restrictions and
conditions applicable to Other Awards. Other Awards under the 2021 Plan include particular grants of partnership interests in Boston Properties Limited Partnership that we call LTIP Units. Each LTIP Unit awarded will be deemed equivalent to an award
of one share of common stock of Boston Properties, Inc. reserved under the 2021 Plan, reducing availability for other equity awards available under the 2021 Plan on a
<FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">one-for-one</FONT></FONT> basis.<B> </B>The 2021 Plan administrator will determine the purchase price, vesting period and other terms and conditions, if any, with respect to the grant
of LTIP Units. If vesting is not attained, the participant will forfeit his or her LTIP Units. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">LTIP Units, whether vested or not, will
receive the same quarterly per unit distributions as common units of in Boston Properties Limited Partnership, which equal per share dividends on shares of common stock of Boston Properties, Inc. Initially, LTIP Units will not have full parity with
common units with respect to liquidating distributions. Upon the occurrence of specified events, LTIP Units will over time achieve full parity with common units of Boston Properties Limited Partnership for all purposes, and therefore accrete to an
economic value for participants equivalent to shares of common stock of Boston Properties, Inc. on a <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">one-for-one</FONT></FONT> basis. If such parity is reached, vested LTIP Units may
be converted into an equal number of common units of Boston Properties Limited Partnership at any time, and thereafter enjoy all the rights of common units. However, there are circumstances under which such parity would not be reached. Until and
unless such parity is reached, the value that a participant will realize for a given number of vested LTIP Units will be less than the value of an equal number of shares of common stock of Boston Properties, Inc. </P>

of Directors and Officers </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The certificate of incorporation of Boston Properties, Inc. contains a provision permitted by the Delaware
General Corporation Law that generally eliminates the personal liability of directors for monetary damages for breaches of their fiduciary duty, including breaches involving negligence or gross negligence in business combinations, unless the
director has breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or a knowing violation of law, paid a dividend or approved a stock repurchase in violation of the Delaware General Corporation Law or
obtained an improper personal benefit. This provision also provides that if the Delaware General Corporation Law is amended in the future to authorize corporate action further eliminating or limiting the personal liability of directors, then the
liability of a director of Boston Properties, Inc. shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended. This provision does not alter a director&#146;s liability under the federal
securities laws. In addition, this provision does not affect the availability of equitable remedies, including an injunction or rescission, for breach of fiduciary duty. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Delaware General Corporation Law permits a corporation to indemnify its directors, officers, employees or agents and expressly provides
that the indemnification provided for under the Delaware General Corporation Law shall not be deemed exclusive of any indemnification right under any <FONT STYLE="white-space:nowrap">by-law,</FONT> agreement, vote of stockholders or disinterested
directors, or otherwise. The Delaware General Corporation Law permits indemnification against expenses and certain other liabilities arising out of legal actions brought or threatened against these persons for their conduct on behalf of a
corporation, provided that each such person acted in good faith and in a manner that he or she reasonably believed was in or not opposed to the corporation&#146;s best interests and, in the case of a criminal proceeding, provided each person had no
reasonable cause to believe his or her conduct was unlawful. The Delaware General Corporation Law does not allow indemnification of directors in the case of an action by or in the right of a corporation unless the directors successfully defend the
action or indemnification is ordered by the court. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The <FONT STYLE="white-space:nowrap">by-laws</FONT> of Boston Properties, Inc. provide
that its directors and officers will be, and, in the discretion of the board of directors of Boston Properties, Inc., <FONT STYLE="white-space:nowrap">non-officer</FONT> employees may be, indemnified to the fullest extent authorized by the Delaware
General Corporation Law, as it now exists or may in the future be amended, against all expenses and liabilities actually and reasonably incurred in connection with service for or on behalf of our company. The
<FONT STYLE="white-space:nowrap">by-laws</FONT> of Boston Properties, Inc. also provide that the right of directors and officers to indemnification shall be a contract right and shall not be exclusive of any other right now possessed or hereafter
acquired under any <FONT STYLE="white-space:nowrap">by-law,</FONT> agreement, vote of stockholders, or otherwise. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Boston Properties, Inc.
and Boston Properties Limited Partnership have entered into indemnification agreements with each of the directors and some of the officers of Boston Properties, Inc. The indemnification agreements require, among other things, that Boston Properties,
Inc. and Boston Properties Limited Partnership indemnify the directors and officers of Boston Properties, Inc. to the fullest extent permitted by law and, advance to the directors and officers of Boston Properties, Inc. all related expenses, subject
to reimbursement if it is subsequently determined that indemnification is not permitted. Under these agreements, Boston Properties, Inc. and Boston Properties Limited Partnership must also indemnify and advance all expenses incurred by the directors
and officers of Boston Properties, Inc. seeking to enforce their rights under the indemnification agreements and may cover the directors and officers of Boston Properties, Inc. under their directors&#146; and officers&#146; liability insurance.
Although the form of indemnification agreement offers substantially the same scope of coverage afforded by law, it provides greater assurance to the directors and officers of Boston Properties, Inc. that indemnification will be available, because,
as a contract, it cannot be modified unilaterally in the future by the Board of Directors or stockholders to eliminate the rights it provides. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The limited partnership agreement of Boston Properties Limited Partnership also generally
provides that Boston Properties, Inc., as general partner of Boston Properties Limited Partnership, will incur no liability to Boston Properties Limited Partnership or any limited partner for losses sustained or liabilities incurred as a result of
errors in judgment or of any act or omission if Boston Properties, Inc. acted in good faith. In addition, Boston Properties, Inc. is not responsible for any misconduct or negligence on the part of its agents, provided Boston Properties, Inc.
appointed such agents in good faith. Boston Properties, Inc. may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisors, and any act taken or omitted to be taken in reliance
upon the opinion of such persons, as to matters that Boston Properties, Inc. reasonably believes to be within their professional or expert competence, shall be conclusively presumed to have been done or omitted in good faith and in accordance with
such opinion. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The limited partnership agreement of Boston Properties Limited Partnership also provides for indemnification, to the
fullest extent permitted by the Delaware law, of Boston Properties, Inc., the directors and officers of Boston Properties, Inc., and such other persons as Boston Properties, Inc. may from time to time designate against any liabilities, expenses and
other amounts arising from any claim or proceeding that relates to the operations of Boston Properties Limited Partnership or Boston Properties, Inc. as set forth in the limited partnership agreement of Boston Properties Limited Partnership in which
such indemnified person is involved, or is threatened to be involved, as a party or otherwise, unless it is established that: (1)&nbsp;the act or omission of the indemnified person was material to the matter giving rise to the preceding and either
was committed in bad faith or was the result of active and deliberate dishonesty; (2)&nbsp;the indemnified person actually received an improper personal benefit in money, property or services; or (3)&nbsp;in the case of any criminal proceeding, the
indemnified person had reasonable cause to believe that the act or omission was unlawful. Under the limited partnership agreement, Boston Properties Limited Partnership generally must also advance all reasonable expenses incurred by an indemnified
person who is a party to proceeding in advance of the final disposition of the proceeding. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">These provisions could reduce the legal
remedies available to Boston Properties, Inc. and its stockholders and Boston Properties Limited Partnership against these individuals. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors,
officers or persons controlling Boston Properties, Inc. or Boston Properties Limited Partnership pursuant to the foregoing provisions, Boston Properties, Inc. and Boston Properties Limited Partnership have been informed that in the opinion of the
staff of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Item&nbsp;7.
