FOR IMMEDIATE RELEASE

Sterling Financial Corporation of Lancaster, Pa.,
Divests Selected Insurance Businesses

LANCASTER, PA (December 27, 2006) – Sterling Financial Corporation has announced the sale of three insurance-related businesses: Corporate Healthcare Strategies, LLC, an employee benefits insurance broker, Professional Services Group, a human resources consulting business, and the property and casualty insurance accounts of the Lancaster Insurance Group, LLC.

“While we found offering these additional services to our customers beneficial as Sterling-owned affiliates, they never became meaningful contributors to the bottom line,” said J. Bradley Scovill, chief revenue officer of Sterling Financial Corporation. “We will continue to provide real estate settlement/title insurance services and offer products such as annuities and life insurance as well as credit-related insurance products.”

Corporate Healthcare Strategies is being purchased by David K. Stoudt, its current president. He is also purchasing the closely related Professional Services Group consulting business. In the third quarter, Sterling took an impairment charge related to changes in the market for employee benefits brokerage services and sold the CapRisk wholesale underwriting portion of Corporate Healthcare Strategies. “This sale simply brings to conclusion the strategic review that we began in the third quarter,” added Scovill.

In the case of Lancaster Insurance Group, the accounts are being sold to Murray Insurance Associates, Inc., the company that has been servicing these accounts since 1999.

“We wanted to do this in a way that would be right for our customers,” said Scovill. “Customers of all three businesses should see little change in their existing service, since it will essentially be the same people, addresses, phone numbers and services offered.”

Each of the businesses referenced has its headquarters in Lancaster.
