COMMON SHARES OF BENEFICIAL INTEREST

 

This prospectus supplement no. 1 supplements and amends the prospectus dated April 3, 2006, relating to the resale from time to time by certain selling shareholders of an aggregate of 8,699,288 of our common shares of beneficial interest (“common shares”), par value $0.01 per share.

 

This prospectus supplement should be read in conjunction with and accompanied by the prospectus and is qualified by reference to the prospectus, except to the extent that the information in this prospectus supplement supersedes the information contained in the prospectus.

 

Since the date of the prospectus, M.O.R. XXIX Associates, L.P., a selling shareholder named in the table under the caption “The Selling Shareholders” in the prospectus, has been liquidated, and has distributed to its limited partners, pro rata, an aggregate of 148,381 common units of limited partnership interests in Corporate Office Properties, L.P, (the “Operating Partnership”) that may, pursuant to our Operating Partnership’s partnership agreement, be presented to us to be redeemed by us for common shares or cash.  Specifically, we have the right, in our sole discretion, to deliver to such redeeming holder for each common unit either one common share (subject to adjustment) or a cash payment equal to the then fair market value of such share determined as provided in the Operating Partnership’s partnership agreement. Unless otherwise indicated, in the table below, the number of common shares presented in the table is equal to the number of common units of limited partnership interests in our Operating Partnership beneficially owned by each selling shareholder.  This information is based upon information provided by such shareholder to the Company.

 

Pursuant to this prospectus supplement, the table under the caption “The Selling Shareholders” in the prospectus is supplemented by the information in the table below to include the selling shareholders named below with respect to the common units of limited partnership interests in our Operating Partnership that were transferred to it, as indicated below.
