SOUTHERN MICHIGAN BANCORP, INC. ANNOUNCES THIRD QUARTER EARNINGS

Coldwater, Michigan, October 31, 2008: Southern Michigan Bancorp, Inc. (OTCBB: SOMC.OB) announced net income of $1,571,000 or $0.69 per diluted share, for the nine months ended September 30, 2008. This compares to $3,129,000, or $1.76 per diluted share, for the nine months ended September 30, 2007. Southern's net income for the three months ended September 30, 2008, was $21,000, or $0.01 per diluted share, compared to $1,082,000, or $0.61 per diluted share, for the same three month period a year ago.

John H. Castle, Chairman & Chief Executive Officer, stated, "Over the last 90 days, we have witnessed unprecedented stress in the financial and credit markets as reflected by recent legislation enacted by Congress and ongoing reports by the media. Southern has avoided many of the issues affecting the broader market, such as sub-prime loans, mortgage-backed securities and investments in Fannie Mae and Freddie Mac stock. However, Southern is not immune to the impact of these trying times, as delinquent and non-accrual loans have increased in both the commercial and consumer portfolios." Castle continued, "While it is impossible to project the magnitude or duration of the issues that presently have stalled the economy, we believe that our conservative credit culture and high lending standards have positioned us to weather the current credit cycle."

Non-performing loans totaled $10,449,000 at September 30, 2008, or 3.1% of total loans. This was an increase of $1,131,000 from June 30, 2008. The third quarter increase in non-performing loans resulted primarily from loans being placed on non-accrual status during the period.

The allowance for loan losses grew to $6,987,000, or 2.07% of total loans, at September 30, 2008, from $5,608,000, or 1.66% of total loans at the prior quarter end and $5,156,000 or 1.53%, at year end 2007. In the third quarter of 2008, provision for loan losses was $1,580,000 compared to $800,000 last quarter and $145,000 in the third quarter of 2007. On a year-to-date basis, Southern's provision for loan losses totaled $2,730,000 versus $345,000 a year ago. Over half of the 2008 increase in the provision for loan losses relates to a single large commercial credit in the automotive industry. The provision for loan losses resulted from management's quarterly evaluation of the loan portfolio using a methodology that estimates the amount of credit losses probable within the loan portfolio based on a number of factors, including loss & delinquency trends, current economic conditions, loan grades and concentrations. The Company and its subsidiary banks continue to be "well capitalized" under regulatory ca pital requirements.

Southern's 4.43% net interest margin for the nine month period ending September 30, 2008 remained strong when compared to peers and was relatively flat compared to the June 30, 2008 six month period of 4.41%. However, Southern's net interest margin declined from the 4.86% reported for the nine month period ending September 30, 2007. The decline is attributable to the

declining rate environment as well as the reversal of interest related to loans placed on non-accrual status.

Financial results for 2008 were influenced by the acquisition of FNB Financial on December 1, 2007. In accordance with the purchase method of accounting, FNB's results of operations were included in Southern's consolidated statements of income from the date of acquisition. As a result of the merger, Southern recorded additional net loans of $76.8 million, securities of $40.2 million and additional deposits of $118.6 million at the time of the acquisition.

Southern Michigan Bancorp, Inc. is a two bank holding company. Its subsidiary banks are Southern Michigan Bank & Trust and FNB Financial. Its 19 offices throughout southern Michigan provide a broad range of consumer, business and wealth management services throughout the region.
