FEBRUARY 10, 2011

MEDFORD, OR – January 20, 2011 – PremierWest Bancorp (NASDAQ: PRWT), the parent company of PremierWest Bank, announced today that it intends to file an amendment to its Articles of Incorporation to complete a 1-for-10 reverse stock split effective February 10, 2011. Shareholders, at a special meeting held on December 16, 2010, approved the reverse stock split. The intention of the reverse stock split is to bring the Company’s stock price above the $1.00 minimum bid price required for continued listing on The NASDAQ Capital Market. PremierWest has until March 10, 2011 to regain compliance.

James Ford, President & Chief Executive Officer of PremierWest Bancorp and PremierWest Bank, stated “While the reverse split will bring us into compliance with NASDAQ listing rules, we understand that profitability is what ultimately drives share price. As evidenced with our fourth quarter report, released earlier today, our focus on improving the financial strength of PremierWest with a goal of returning the company to profitability as soon as possible is showing positive signs. We will continue to work vigorously at improving our financial performance, and our shareholders investment.”
