To Our Shareholders:

Mack-Cali is a company defined by focus. Over the years, our greatest success has been achieved by staying true to a consistent and conservative strategy. We continued that approach in 2003. By providing our tenants with magnificent work environments, we maintained strong occupancies despite a challenging economy. We added to our already deep presence in core markets and further reduced our holdings in non-strategic markets. We secured additional financing that enhanced our balance sheet and improved our ability to take advantage of opportunity. And we progressed on a large-scale "smart growth" development project for which we are uniquely qualified by our experience and market knowledge.

Succeeding in Challenging Times
This past year did have its challenges. Businesses—especially large employers— continued to be reluctant to make long-term decisions about capital spending and business expansion. And while the nation's economy has started to show signs of recovery, this has yet to translate into noteworthy employment growth, which is the key driver of office space demand. A widespread real estate recovery will not occur until there is sustained eco-nomic expansion that gives businesses the confidence to add staff.
         Our portfolio's occupancy did slip slightly in 2003—to 91.5% leased at year-end from last year's 92.3%. The decline can be attributed in part to the addition of a new development, Harborside Financial Center Plaza 5, to our leasing statistics. However, our net leasing activity produced positive absorption of over 140,000 square feet—a commendable achievement given the year's economic conditions.

           Our strategy of operating in high-barrier- to-entry markets in the Northeast and Mid-Atlantic regions continued to protect us from serious problems with occupancy. Most of these markets, which span from Washington, D.C., up through Connecticut, have diverse macro economies and limited inventories of new class A office space, and consequently are outperforming other markets throughout the country on the demand side of the equation.
         While we have yet to see any widespread recovery, we have begun to see improvement in certain markets and submarkets. Among those areas is the Jersey City waterfront, home to our Harborside Financial Center, a 3.6 million square-foot "city within a city." Harborside benefited from two events in late 2003: the reinstatement of New Jersey's Business Employment Incentive Program (BEIP) and the return of PATH train service. The BEIP program provides financial incentives to companies relocating to New Jersey. It has proved valuable in attracting tenants to the state, and especially to the Jersey City waterfront, which draws businesses from Manhattan. After being disrupted by the attacks of September 11, 2001, PATH train service between the Exchange Place station, adjacent to Harborside, and downtown Manhattan's World Trade Center station was completely restored in November. As a result, Harborside is again just a four-minute train ride from the financial district of New York City. The return of this excellent access is enhancing the leasing prospects at our new development, Harborside Plaza 5. Over the last few months, we've signed four new leases for over 91,000 square feet at the building, reflecting the renewed interest in the market.
