Kathy Klein Vice President Corporate Communications 301/998-8211 FEDERAL REALTY INVESTMENT TRUST ANNOUNCES 1998 OPERATING RESULTS February 10, 1999 Rockville, Maryland Federal Realty Investment Trust (NYSE:FRT) reported today that funds from operations for the year ended December 31, 1998 increased 9% to $87 million from $80 million in 1997. On a per share basis, funds from operations rose 5% to $2.16 per share in 1998 from $2.05 in 1997. This increase was achieved despite the change in accounting policy effective earlier this year (EITF 97-11) that requires the expensing of certain internal acquisition costs. If the 1997 results were adjusted for the accounting change, funds from operations per share would have increased 7% from 1997 to 1998. Funds from operations for the fourth quarter of 1998 rose 10% to $23 million from $21 million in the fourth quarter of 1997. On a per share basis, funds from operations per share increased 8% to $.57 in the fourth quarter of 1998 as compared to $.53 per share in the comparable period of 1997. A comparison of property operations for the year ended 1998 versus 1997 shows the following: . Rental income increased 18% to $222 million in 1998 from $189 million in 1997. When adjusted to exclude properties acquired and sold during 1997 and 1998, rental income increased 5% to $187 million in 1998 from $177 million in 1997. . During 1998, the Trust signed leases for a total 1.4 million square feet of retail space. On a same space basis, the Trust re-leased 1.1 million square feet of retail space at an average increase in rent per square foot of 17%. The weighted average rent on these leases was $17.62 per square foot compared to the previous average rent of $15.12 per square foot. During 1997, the Trust leased a total 1.4 million

square feet. On a same space basis, 1.1 million square feet was re- leased at an average increase in rent per square foot of 17%. The weighted average rent on these leases was $16.40 per square foot compared to the previous average rent per square foot of $14.01. . Same property occupancy stood at 95.0% at year end December 31, 1998 and 95.6% at year end 1997. The Trust's overall portfolio was 95.2% leased at December 31, 1998 as compared to 95.6% a year ago. Commenting on the results, Steven Guttman, President and Chief Executive Officer stated, "We are optimistic about our long-term growth prospects. Demand for our retail space remains strong as evidenced by our rental income growth and high occupancy levels. In addition, our comprehensive corporate reengineering initiative is expected to yield cost and revenue opportunities that will add positively to our growth beginning in 1999. We continue to benefit from our acquisition and redevelopment efforts and have strengthened our development capabilities and formed strategic partnerships that will enable us to maximize and expand our pipeline of retail and mixed-use urban development and redevelopment opportunities. Collectively, these initiatives should position us for accelerated growth in 1999 and beyond."
