Properties Trust (&#8220;COPT&#8221; and, collectively with its subsidiaries, including COPLP, the &#8220;Company&#8221;), priced
a public offering (the &#8220;Offering&#8221;) of $400.0</span> million aggregate principal amount of its 2.250% Senior Notes due 2026
(the &#8220;Notes&#8221;). In connection with the Offering, COPT and COPLP entered into an Underwriting Agreement with Wells Fargo
Securities, LLC and J.P. Morgan Securities LLC as representatives of the several underwriters named therein, that provides for
the issuance and sale of the Notes by COPLP. The offering of the Notes is registered under the Securities Act of 1933, as amended
(the &#8220;Securities Act&#8221;), pursuant to the Registration Statement on Form&#160;S-3 (File No.&#160;333-230764) filed by

of the Notes, the Company will recognize approximately $53 million in losses related to certain derivative financial instruments
previously designated as cash flow hedges of interest expense on $225 million of forecasted future borrowings that the Company
expects to determine, upon the issuance of the Notes, will probably not occur. Also, in connection with the Offering, the Company
commenced a cash tender offer (the &#8220;Tender Offer&#8221;) to purchase any and all of COPLP&#8217;s 3.700% Senior Notes due
2021 (the &#8220;2021 Notes&#8221;). To the extent that the Tender Offer is not consummated or not subscribed in full, the Company intends
to use the net proceeds from the Offering to fund the redemption of all of COPLP&#8217;s 2021 Notes not purchased in the Tender
Offer. In connection with the expected purchase or redemption of the 2021 Notes, the Company expects to incur approximately $9
million of losses on the early extinguishment of this debt.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company uses the non-GAAP financial
measures described below in earnings press releases and information furnished to the Securities and Exchange Commission. The Company
believes that these measures are helpful to investors in measuring its performance and comparing such performance to other real
estate investment trusts (&#8220;REITs&#8221;). Since these measures exclude certain items includable in their respective most
comparable GAAP measures, reliance on the measures has limitations; management compensates for these limitations by using the measures
simply as supplemental measures that are weighed in balance with other GAAP and non-GAAP measures. These measures are not necessarily
indications of the Company&#8217;s cash flow available to fund cash needs. Additionally, they should not be used as an alternative
to the respective most comparable GAAP measures when evaluating the Company&#8217;s financial performance or to cash flow from
operating, investing and financing activities when evaluating the Company&#8217;s liquidity or ability to make cash distributions
or pay debt service.</p>

sales and impairment losses of real estate (net of associated income tax) and real estate-related depreciation and amortization.&#160;
FFO also includes adjustments to net income for the effects of the items noted above pertaining to unconsolidated real estate joint
ventures (&#8220;UJVs&#8221;) that were allocable to the Company&#8217;s ownership interest in the UJVs. The Company believes that
it uses the National Association of Real Estate Investment Trust&#8217;s (&#8220;Nareit&#8221;) definition of FFO, although others
may interpret the definition differently and, accordingly, the Company&#8217;s presentation of FFO may differ from those of other
REITs.&#160; The Company believes that FFO is useful to management and investors as a supplemental measure of operating performance
because, by excluding gains on sales and impairment losses of real estate (net of associated income tax) and real estate-related
depreciation and amortization, FFO can help one compare its operating performance between periods.&#160; The Company believes that
net income is the most directly comparable GAAP measure to FFO.</p>

(3)&#160;depreciation and amortization allocable to noncontrolling interests in other consolidated entities, (4)&#160;Basic FFO
allocable to share-based compensation awards and (5)&#160;issuance costs associated with redeemed preferred shares.&#160; With
these adjustments, Basic FFO represents FFO available to common shareholders and holders of common units in the Operating Partnership
(&#8220;common units&#8221;).&#160; Common units are substantially similar to the Company&#8217;s common shares of beneficial interest
(&#8220;common shares&#8221;) and are exchangeable into common shares, subject to certain conditions.&#160; The Company believes
that Basic FFO is useful to investors due to the close correlation of common units to common shares.&#160; The Company believes
that net income is the most directly comparable GAAP measure to Basic FFO.</p>

Basic FFO that would result from the assumed conversion of securities that are convertible or exchangeable into common shares.&#160;
The computation of Diluted FFO assumes the conversion of common units but does not assume the conversion of other securities that
are convertible into common shares if the conversion of those securities would increase Diluted FFO per share in a given period.&#160;
The Company believes that Diluted FFO is useful to investors because it is the numerator used to compute Diluted FFO per share,
discussed below.&#160; The Company believes that net income is the most directly comparable GAAP measure to Diluted FFO.</p>

properties (including property net operating income, interest expense and gains on debt extinguishment); loss on interest rate
derivatives; demolition costs on redevelopment and nonrecurring improvements; executive transition costs; issuance costs associated
with redeemed preferred shares; allocations of FFO to holders of noncontrolling interests resulting from capital events; and certain
other expenses that the Company believes are not closely correlated with its operating performance.&#160; This measure also includes
adjustments for the effects of the items noted above pertaining to UJVs allocable to the Company&#8217;s ownership interest in
the UJVs.&#160; The Company believes&#160;this to be a useful supplemental measure alongside Diluted FFO as it excludes gains and

of FFOPS assumes the conversion of common units but does not assume the conversion of other securities that are convertible into
