HUDSON PACIFIC CONTINUES OFFICE PORTFOLIO GROWTH WITH

ACQUISITION OF 222 KEARNY STREET IN SAN FRANCISO

LOS ANGELES—October 11, 2010 – Hudson Pacific Properties (NYSE:HPP) has completed the $34.9 million acquisition of the 144,440-square-foot, two-building, 222 Kearny Street office property in San Francisco’s North Financial District from an affiliate of Canyon Capital Realty Advisors.

“Our relationship with the seller, which we have developed over many years, led to the opportunity to acquire this property through an off-market transaction. This is a good fit with our investment strategy, an attractive office property at a premier location in the heart of San Francisco for good value,” said Howard S. Stern, president, Hudson Pacific Properties. “San Francisco is one of our company’s top targets for expansion. We will continue to grow our presence here through the acquisition of other well-located-office properties.”

222 Kearny Street, located at the northeast corner of Sutter and Kearny Streets, is comprised of two buildings, a 10-story office tower built in 1986 and the five-story, 180 Sutter Street building built in 1915. The historic low rise building located at 180 Sutter boasts a distinctive articulated façade and substantial interior renovations complementing the adjacent Class A, 10-story glass and steel tower at 222 Kearny, both of which benefit from one of the city’s major pedestrian and transit corridors. A portion of the 222 Kearny building sits on a long-term ground lease.

“With easy access to both the financial district and Union Square shopping and dining, in the hub of the area’s public transportation network, it is a popular location choice for a variety of businesses from professional service firms to creative technology companies,” Stern added.

Hudson Pacific Properties also owns 875 Howard Street, a 286,000-square-foot office property South of Market across from the Moscone Convention Center.
