Whitestone REIT Acquires The Shops at Pinnacle Peak for $6.4 Million

Strategic Location Solidifies Market Presence in North Scottsdale

Houston, Texas, May 29, 2012 – Whitestone REIT (NYSE-AMEX: WSR – “Whitestone”), a fully integrated real estate company that owns, operates and re-develops Community Centered PropertiesTM, which are visibly located properties in established or developing culturally diverse neighborhoods, announced today that it has closed on the purchase of The Shops at Pinnacle Peak, a 41,530 square foot 76% leased Class A Community Center in North Scottsdale, for $6.4 million, or $154 per square foot. The purchase price is a 32% discount to estimated replacement cost.

“The Shops at Pinnacle Peak is strategically positioned in the marketplace on Pinnacle Peak Road, midway between our Pinnacle of Scottsdale (at Scottsdale Road) and The Citadel (at Pima Road). We now own a relatively large share of smaller service-based tenant space – over 183,000 square feet within this two-mile stretch – in the affluent North Scottsdale submarket. We have an immediate transformation plan for The Shops at Pinnacle Peak to add value with complementary neighborhood enhancements to the common area that welcome and serve the local community,” said James C. Mastandrea, Whitestone’s Chairman and Chief Executive Officer. “Phoenix and the North Scottsdale market remain a long-term growth market with early signs of strong recovery, adding population especially in the 35-55 ‘up and coming’ age range and ranking third in growth behind Dallas and Houston, two of Whitestone’s other markets. Whitestone continues to seek Community Center acquisition opportunities in the Phoenix metro area and also is working with sellers who may benefit from a tax efficient transaction in which operating partnership units are exchanged.”

Whitestone now owns six Community Centers within the significant “four corners” of the North Scottsdale trade area, including The Shops at Pinnacle Peak. The other Centers are Terravita (northwest), Pima Norte (northeast in the Cave Creek area), The Citadel (southeast), and Pinnacle of Scottsdale (southwest), in addition to Desert Canyon, located in the McDowell Mountain area. All purchases were priced at a discount to current replacement cost and have a value-add component. Each of these Community Centers are located at high traffic intersections in stabilized neighborhoods, and provide essential services to support local communities including Terravita, McDowell Mountain Ranch, Grayhawk, DC Ranch, Silverleaf, Estancia, Desert Highlands, and Troon North Villages. Whitestone also owns three other Community Centers in the greater Phoenix market: Ahwatukee Plaza, MarketPlace at Central, and Gilbert Tuscany Village.

About The Shops at Pinnacle Peak
The Shops at Pinnacle Peak is located on the southeast corner of the intersection of Pinnacle Peak Road at Miller Road, with a traffic count of over 29,000 cars per day. A new luxury multi-family housing development is planned to be constructed on the land just west at Silverstone.1 The tenant mix at The Shops at Pinnacle Peak is typical of Whitestone’s Driving Traffic/Driving ValueTM Community Center tenant combination, and includes several privately owned restaurants, medical/health care service providers, an educational provider, and a variety of other convenience service providers.
