DIXON, Calif. -- First Northern Community Bancorp (OTCBB:FNRN), holding company for First Northern Bank, today announced record earnings for the first quarter of 2006. Net income for the quarter ended March 31, 2006 was $2.40 million, up 42.01% from the $1.69 million earned in the same period in 2005.

During that same period, total net loans (including loans held-for-sale) increased $12.3 million, or 2.7%, to $468.0 million.

Owen "John" Onsum, President and CEO stated, "We are extremely pleased to report our company's first quarter 2006 performance. We had another record quarter with strong results in all key performance areas of our business. It is important to point out that while the provision for loan loss recovery does give a boost to our numbers, it should not diminish the fact that record numbers would have been achieved without the recovery. Our success in part is due to the continued gradual increases in interest rates and the positive effects they've had on our margins, our Company's growing customer base, as well as the increasing productivity of our new offices."
