Apartment Community Acquisitions Increase Presence in Growth Markets

During the second quarter, the Company acquired four apartment communities with 1,286 apartment homes for a total purchase price of $219 million, averaging $170,300 per home.

• The Company acquired two communities within close proximity in San Ramon, California. One was purchased for $56.3 million. The community includes 250 homes of 1, 2, and 3 bedroom floor plans, averaging 942 square feet, with average monthly collections of $1,516 per home. Construction was completed in late 2005 and is currently 94% leased. The Company will consider this property for future condominium conversion.

• The other San Ramon community was purchased for $90.0 million and includes 400 homes. The property includes a mixture of 1, 2, and 3 bedroom floor plans, averaging 953 square feet, with average monthly collections of $1,498. This property was completed in the second quarter of 2006 and is in lease-up, currently 74% leased. Stabilization is expected in first quarter, 2007.

• The Company acquired a 250 home community located in San Diego, California for $51.8 million. The community consists of 1 and 2 bedroom floor plans, averaging 765 square feet per home. The average monthly collections are $1,268 per home. It was completed in 1986 and has undergone modest interior renovations. The Company will continue to upgrade the property with additional improvements, including new kitchens and baths. The community has recently been approved for a tentative condominium map, making it a future condominium conversion candidate.

• The Company purchased an apartment community in Nashville, Tennessee, for $21.0 million. The community includes 386 homes averaging 704 square feet with average monthly collections of $624 per home. This property was completed in two phases in 1987 and 1990, with exterior renovations completed in 2005. The Company will consider upgrading the homes with new kitchens and baths.

Dispositions Accelerate

During the second quarter, the Company sold seven apartment communities with 1,903 homes for $89 million.

• The Company sold a portfolio of six properties consisting of 1,711 homes in submarkets of Dallas and Fort Worth, Texas for $74.5 million. The sale produced a gain of $17.9 million.

• The Company also sold a 192 home community in Mesa, Arizona for $14.6 million and a gain of $8.1 million.

In addition to sales that closed in the second quarter, 3,353 homes located in the Carolinas, Tennessee and Colorado are under contract for $160 million and are expected to close in the third quarter.

“These sales are at outstanding prices and represent the Company’s ability to capture value created by the demand for institutional-quality apartments in job growth markets,” stated W. Mark Wallis, Senior Vice President. “We continually evaluate our portfolio and sell selected communities as we execute our strategy of value creation.”

Management Additions, Leadership Positions

The Company announced several significant additions to the management team in the second quarter. Mike Ernst was named Executive Vice President, Treasurer and Chief Financial Officer. He brings 20 years of experience in financial management and leadership in capital markets activity to the Company. Also, Mark Culwell and Doug Walker joined the Company as Senior Vice Presidents in the Development Group. They are both seasoned leaders with extensive knowledge and experience in real estate development and redevelopment. The Company has intensified its focus in these areas and these additions confirm the commitment to growing this important aspect of the business.

In May, Cheryl Pucci, Vice President, Operations, was installed as President of the Texas Apartment Association. She has been active in the Texas and National Apartment Associations for the past twelve years and currently serves as a Texas delegate to the National Apartment Association, representing the industry on legislative issues. Cheryl joins Kathy Ratchford, District Manager and Assistant Vice President, who also serves in an industry leadership position as President of the Florida Apartment Association.

Earnings Guidance

The Company believes that financial results for 2006 will be affected by international, national and regional economic trends and events, the acquisition and/or disposition of apartment communities, portfolio repositioning, financing activities, and other factors. The Company’s guidance for third quarter 2006 FFO is $0.40 to $0.42 per share (diluted) and $1.65 to $1.73 per share (diluted) for the full year 2006. All guidance is based on the current expectations and judgment of the Company’s management team.

A reconciliation of the range provided for projected 2006 FFO per share for the full year to Earnings Per Share (“EPS”) for the full year is as follows:

	2006
Funds From Operations (a)	$	1.73		$	1.65
Conversion to GAAP Share Count (b)		0.16			0.15
Minority Interest of OP Unit Holders (b)		(0.03	)		(0.05	)
Depreciation (c)		(1.70	)		(1.65	)
Gains (c)		0.50			0.70
Preferred Dividends		(0.09	)		(0.09	)
Expected Earnings Per Share	$	0.57		$	0.71

(a) The National Association of Real Estate Investment Trusts (“NAREIT”) defines funds from operations (“FFO”) (April 2002 White Paper) as net income (computed in accordance with accounting principles generally accepted in the United States (GAAP)), excluding gains (or losses) from sales of depreciable property, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. The Company believes that FFO is helpful to investors as a supplemental measure of the operating performance of a real

5

	estate company because it provides investors an understanding of the ability of the Company to incur and service debt and to make capital expenditures. FFO in and of itself does not represent net income or net cash flows from operating activities in accordance with GAAP. Therefore, FFO should not be exclusively considered as an alternative to net income or to net cash flows from operating activities as determined by GAAP or as a measure of liquidity.
(b)	Operating Partnership units are not considered to be common stock equivalents for GAAP purposes.
(c)	Due to the uncertain timing and extent of property dispositions and acquisitions, actual results could differ materially from expected EPS.

FFO is defined as net income (computed in accordance with GAAP), excluding gains (or losses) from sales of depreciable property, plus real estate depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. This definition conforms with the National Association of Real Estate Investment Trust’s definition issued in April 2002. United Dominion considers FFO in evaluating property acquisitions and its operating performance and believes that FFO should be considered along with, but not as an alternative to, net income and cash flows as a measure of United Dominion’s activities in accordance with generally accepted accounting principles and is not necessarily indicative of cash available to fund cash needs.

Net incremental gains on the sale of condominium homes and the gains on the disposition of real estate developed for sale are defined as net sales proceeds less a tax provision (based on our annual estimated tax liability which could differ from amounts recorded per GAAP) and the gross investment basis of the asset before accumulated depreciation. We consider FFO with the net incremental gains on the sale of condominium homes to be a meaningful supplemental measure of performance because the short-term use of funds produce a profit which differs from the traditional long-term investment in real estate for REITs.
