This Supplement presents certain information regarding the ownership of our common stock by the Selling Shareholders as of March 12, 2010, and updates the number of shares of our common stock available for resale by each Selling Shareholder pursuant to the Plans. No additional securities are being registered hereby.
          You should read this Supplement in conjunction with the Prospectus. This Supplement is qualified by reference to the Prospectus, except to the extent the information in this Supplement supersedes the information contained in the Prospectus.
          The Selling Shareholders may offer their shares of Common Stock through public or private transactions, in the over-the-counter markets or on any exchanges on which our Common Stock is traded at the time of sale, at prevailing market prices or at privately negotiated prices. The Selling Shareholders may engage brokers or dealers who may receive commissions or discounts from the Selling Shareholders. We will pay substantially all of the expenses incident to the registration of such shares, except for selling commissions.
          Our Common Stock is listed on The New York Stock Exchange under the symbol “CLI.” The closing price of our Common Stock as reported on The New York Stock Exchange on March 10, 2010 was $34.25 per share.
          You should carefully read and consider the risk factors under Item 1A beginning on page 8 in our Annual Report on Form 10-K for the year ended December 31, 2009 for risks relating to investments in our securities.
          Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus supplement. Any representation to the contrary is a criminal offense.

SELLING SHAREHOLDERS
     The Selling Shareholders are persons listed in the table below who have acquired the common stock offered by this Supplement in conjunction with the Prospectus pursuant to our 2000 Employee Stock Option Plan or our Amended and Restated 2000 Director Stock Option Plan. Each Selling Shareholder will receive all of the net proceeds from the sale of his shares of common stock offered by this Supplement in conjunction with the Prospectus.
     The following table presents certain information regarding the ownership of our common stock by the Selling Shareholders as of March 12, 2010. The number of shares of common stock outstanding will not change as a result of the offering, nor will the number of shares owned or percentage of ownership of any persons other than the Selling Shareholders change as a result thereof. However, because the Selling Shareholders may offer from time to time all or some of their shares under this Supplement, or in another permitted manner, no assurances can be given as to the actual number of shares that will be sold by the Selling Shareholders or that will be held by the Selling Shareholders after completion of the sales.
     The information contained in the following table is as of March 12, 2010, and supersedes and replaces the table of Selling Shareholders, and the related footnotes, contained in the Prospectus.
