Rockville Bank to Open Branch in West Hartford Center

ROCKVILLE, CONN., October 28, 2011 — William (Bill) H. W. Crawford, IV, President and Chief Executive Officer (CEO) of Rockville Bank and Rockville Financial, Inc. (NASDAQ Global Select Stock Market: “RCKB”) today announced that Rockville Bank has filed an application with the Connecticut State Department of Banking for approval to open a full-service branch in West Hartford, Conn.

The new Rockville Bank location will be at 102 LaSalle Road in West Hartford Center. The branch will occupy the same building as the U.S. Post Office, which will continue to operate. The Bank will have its own public entrance and offices, free parking spaces for customers, a convenient drive-up teller window, and an ATM.

“We are very excited about having a significant presence in West Hartford Center and plan to open our doors in the third quarter of 2012,” explains William (Bill) H. W. Crawford, IV, President and Chief Executive Officer (CEO) of Rockville Bank. “In addition to our wide range of personal customer products and services, our new branch will feature Rockville Bank commercial and business banking teams. This will be our second Bank office located west of the Connecticut River, and it is part of our Company’s plans to expand the reach of our branch network.”

“We are excited to have so many personal and commercial customers in the West Hartford community and look forward to meeting more of our neighbors, civic leaders and local businesses, and getting involved in the community in a variety of ways,” adds Crawford.

Udolf Properties acquired the 102 LaSalle Road property and is working with Rockville Bank on modifications for the Bank’s offices in the North side of the building; the U.S. Post Office will be located in another part of the structure. “We are delighted to welcome Rockville Bank to West Hartford,” says Leonard Udolf, owner of Udolf Properties. “We’ve been a longtime Bank customer and believe their sterling reputation and customer service matches perfectly within the community and the Center.”

“This site already is one of West Hartford’s and Greater Hartford’s premier parcels of commercial property,” notes Udolf. “New paving and lighting of the more than 60-space parking lot, along with changes to the building’s façade, will further enhance West Hartford Center as a top destination in Connecticut.”
