The following is a summary of the Company’s recent activity:

All per share amounts presented above are on a diluted basis.

The Company had 62,230,447 shares of common stock, 10,000 shares of 8 percent Series C cumulative redeemable perpetual preferred stock ($25,000 liquidation value per share), and 15,558,056 common operating partnership units outstanding as of March 31, 2006.

The Company had a total of 77,788,503 common shares/common units outstanding at March 31, 2006.

The Company had an interest coverage ratio of 3.6 times for the quarter ended March 31, 2006.

Acquisitions

In March, the Company completed its acquisition of all the interests in Capital Office Park, a seven-building class A office complex totaling approximately 842,300 square feet in Greenbelt, Maryland, for approximately $161.7 million. In addition to the assumption of approximately $63.2 million of mortgage debt, the Company issued 1,942,334 common operating partnership units in Mack-Cali Realty, L.P. valued at $87.2 million, and paid the balance in cash. The agreement also provides the Company the option to acquire approximately 43 acres of adjacent land sites to accommodate the development of up to 600,000 square feet of office space for $13 million.

•

Acquire approximately one-half of the ownership interests in seven class A office properties, valued at $127.5 million, and totaling approximately 900,000 square feet, also in Northern and Central New Jersey.

The transactions will be financed through a combination of the assumption of existing, and placement of new, mortgage debt, credit facility drawings, cash and the issuance of common operating partnership units.

Development

In March, the Company entered into a joint venture agreement with The PRC Group to develop a 92,878 square-foot class A office building in Red Bank, New Jersey. The entire building has been pre-leased to Hovnanian Enterprises, Inc. for 10 years, and will be developed by the Company. Expected to be completed by the third quarter of 2007, the building includes 88,000 square feet of office space, 4,878 square feet of retail space, and a four-story parking garage. The property will be developed on a 3.4-acre land site located at 141 West Front Street in downtown Red Bank contributed to the joint venture by The PRC Group.

Financing Activity

In January, the Company’s operating partnership, Mack-Cali Realty, L.P., sold $200 million of senior unsecured notes, comprised of $100 million of six-year notes and $100 million of 10-year notes. The six-year notes bear interest at 5.25 percent, are due January 15, 2012, and were priced to yield 5.48 percent. The 10-year notes are a re-opening of previously-issued $100 million, 5.80 percent notes due January 15, 2016, which were re-opened at 101.081 to yield 5.65 percent, plus accrued interest. Following the re-opening, the outstanding size of the 5.80 percent notes is $200 million. The proceeds from the issuance of both series of notes of approximately $200.8 million were applied to the repayment of outstanding borrowings under the Company’s $600 million unsecured revolving credit facility.

Dividends

In March, the Company’s Board of Directors declared a cash dividend of $0.63 per common share (indicating an annual rate of $2.52 per common share) for the first quarter 2006, which was paid on April 17, 2006 to shareholders of record as of April 5, 2006.

The Board also declared a cash dividend on its 8 percent Series C cumulative redeemable perpetual preferred stock ($25 liquidation value per depositary share, each representing 1/100^th of a share of preferred stock) equal to $0.50 per depositary share for the period January 15, 2006 through April 14, 2006. The dividend was paid on April 17, 2006 to shareholders of record as of April 5, 2006.

Mack-Cali Realty Corporation

Supplemental Operating and Financial Data for the Quarter Ended March 31, 2006

Information About FFO

Funds from operations (“FFO”) is defined as net income (loss) before minority interest of unitholders, computed in accordance with generally accepted accounting principles (“GAAP”), excluding gains (or losses) from extraordinary items and sales of depreciable rental property (which the Company believes includes unrealized losses on properties held for sale), plus real estate-related depreciation and amortization. The Company believes that FFO per share is helpful to investors as one of several measures of the performance of an equity REIT. The Company further believes that by excluding the effect of depreciation and gains (or losses) from sales of properties (all of which are based on historical costs which may be of limited relevance in evaluating current performance), FFO per share can facilitate comparison of operating performance between equity REITs. FFO per share should not be considered as an alternative to net income per share as an indication of the Company’s performance or to cash flows as a measure of liquidity. FFO per share presented herein is not necessarily comparable to FFO per share presented by other real estate companies due to the fact that not all real estate companies use the same definition. However, the Company’s FFO per share is comparable to the FFO per share of real estate companies that use the current definition of the National Association of Real Estate Investment Trusts (“NAREIT”). A reconciliation of net income per share to FFO per share is included in the financial tables on page 27.

(a)

Percentage leased includes all leases in effect as of the period end date, some of which have commencement dates in the future (including a lease with commencement date substantially in the future consisting of 15,125 square feet scheduled to commence in 2009), and leases expiring March 31, 2006 aggregating 95,861 square feet (representing 0.3 percent of the Company’s total net rentable square footage) for which no new leases were signed.

(b)

Total base rent for the 12 months ended March 31, 2006, determined in accordance with generally accepted accounting principles (“GAAP”). Substantially all of the leases provide for annual base rents plus recoveries and escalation charges based upon the tenant’s proportionate share of and/or increases in real estate taxes and certain operating costs, as defined, and the pass through of charges for electrical usage.

(c)	Excludes space leased by the Company.

(d)	Base rent for the 12 months ended March 31, 2006, divided by net rentable square feet leased at March 31, 2006. For those properties acquired during the 12 months ended March 31, 2006, amounts are annualized, as per Note e.

(e)

As this property was acquired by the Company during the 12 months ended March 31, 2006, the amounts represented in 2006 base rent reflect only that portion of the year during which the Company owned the property. Accordingly, these amounts may not be indicative of the property’s full year results. For comparison purposes, the amounts represented in 2006 average base rent per sq. ft. for this property have been calculated by taking 2006 base rent for such property and annualizing these partial-year results, dividing such annualized amounts by the net rentable square feet leased at March 31, 2006. These annualized per square foot amounts may not be indicative of the property’s results had the Company owned such property for the entirety of the 12 months ended March 31, 2006.

(f)	This property was identified as held for sale by the Company as of March 31, 2006 and is classified as discontinued operations in the 2006 financial statements.

(g)	Includes $2,115 pertaining to properties identified as held for sale, which are classified as discontinued operations in the 2006 financial statements.
