and Officers </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The certificate of incorporation of BXP 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 BXP 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; 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; font-size:10pt; font-family:Times New Roman">The <FONT
STYLE="white-space:nowrap">by-laws</FONT> of BXP provide that its directors and officers will be, and, in the discretion of the board of directors of BXP, <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 BXP. The <FONT
STYLE="white-space:nowrap">by-laws</FONT> of BXP 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; font-size:10pt; font-family:Times New Roman">BXP has entered into indemnification agreements with each of the
directors and some of the officers of BXP. The indemnification agreements require, among other things, that BXP indemnify the directors and officers of BXP to the fullest extent permitted by law and, advance to the directors and officers of BXP all
related expenses, subject to reimbursement if it is subsequently determined that indemnification is not permitted. Under these agreements, BXP must also indemnify and advance all expenses incurred by the directors and officers of BXP seeking to
enforce their rights under the indemnification agreements and may cover the directors and officers of BXP 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 BXP 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>

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&#8201;7. Exemption
