Dear Shareholder:

I am pleased to report that Mack-Cali had some solid first quarter leasing activity. (For more information on our results and accomplishments, please refer to our first quarter earnings press release, supplemental package and 10Q.) I also welcome you to view our 2008 annual report.

As well, Mack-Cali was recently ranked among the nation's 100 most trustworthy companies, based on a survey commissioned by Forbes.com. The survey analyzed over 8,000 companies, identifying those that have consistently shown transparent and conservative accounting practices and solid corporate governance and management.

While we have previously announced two mortgage transactions completed this quarter, they are worthy of mention again. These mortgages, totaling $64.5 million, are a clear indication of the Company's strength and stability and the quality of our assets.

We are pleased that even in these challenging markets, we have maintained our competitive advantage and market leadership. Tenants are increasingly looking for financially strong landlords. In a Mack-Cali building, tenants know they have chosen a landlord who remains committed to reinvesting capital in its properties and has the resources available to do just that.

Thank you for your interest in Mack-Cali.

Sincerely,
