5.03 AMENDMENT TO ARTICLES OF INCORPORATION OR BYLAWS; CHANGE IN FISCAL
YEAR.
On
December 11, 2008, the Board of Directors (the "Board") of Kilroy Realty
Corporation (the "Company") adopted and approved the Second Amended and Restated
Bylaws of the Company (the "Amended Bylaws") to be effective
immediately.  The Amended Bylaws revise the Company's existing Bylaws
to (1) incorporate a prior amendment; (2) clarify the procedures by which a
stockholder may request a special meeting; (3) clarify the procedures for the
organization and conduct of stockholder meetings; (4) clarify that, except for
proposals properly brought under Rule 14a-8 under the Securities and Exchange
Act of 1934, as amended, the advance notice bylaw provisions apply to all
stockholder proposals and nominations of candidates for election as directors,
and the procedures set forth in such advance notice bylaw provisions shall be
the exclusive means for a stockholder to properly bring business before an
annual meeting of stockholders; (5) require stockholders who provide advance
notice of proposals or nominations to provide additional information to the
Company as part of such notice, including information regarding the
stockholder's beneficial ownership of derivative, swap, hedge, repurchase, short
or similar positions with respect to the Company's securities; and (6) make
certain other technical amendments.
The
foregoing description of the Amended Bylaws is qualified in its entirety by
reference to the full text of the Amended Bylaws, a copy of which is attached as
