Exhibit 99

Quarterly Shareholder Brochure of CNB Corporation

April 10, 2008

Dear Shareholders:

CNB Corporation's net income for the first quarter of 2008 was $665,000 or $
0.55 basic earnings per share compared to $630,000 or $0.51 basic earnings per
share for the same period last year, an increase of 5.7 %. Assets of the
Corporation at the end of the first quarter were $262.6 million compared with
$260.5 million last year, an increase of 0.8%. Deposits at the end of the first
quarter increased 1.1% to $232.7 million, compared with $230.2 million the same
time last year. Loans as of March 31, 2008 were $176.2 million, compared to
$168.4 million at March 31, 2007, an increase of 4.6%.

Despite the increases over last year, the loan portfolio has been impacted by
Michigan's economic downturn. Loan losses for the first quarter 2008 were
$317,400 which is the highest level we have experienced in several years. The
losses are primarily in the commercial loan portfolio, although some residential
mortgage customers are struggling as well. Such losses are not unique to
Citizens National Bank or to northern Michigan; banks state-wide are
experiencing increases in charge-offs, non-accrual loans and other real estate
owned, while declines in collateral values across the market exacerbates the
situation further. Management is taking an aggressive approach in working
through these problem credits but anticipates there may be further losses in the
next quarter. In response, the provision to the loan loss reserve has been
increased to ensure an adequate reserve for anticipated future losses.
Fortunately, as previously reported to our shareholders, we have no exposure to
the sub-prime mortgage lending market.

At its March 27, 2008 meeting the Board of Directors of CNB Corporation declared
a $0.42 per share dividend payable to shareholders of record on that date. The
dividend paid last year was also $0.42. Although shareholder's equity remained
unchanged at $25.2 million, book value increased to $20.79 at March 31, 2008
compared to $20.33 at March 31, 2007. The increased book value in 2008 is due to
fewer shares outstanding as a result of the 2007 stock repurchase program.

We expect that 2008 will continue to be a challenge for the entire financial
services industry, but believe by identifying and addressing problem credits
early-on and in a forthright manner, we will meet and overcome the challenges
ahead.

I hope to see you at the annual meeting on May 20th.

Sincerely,

Susan A. Eno
President and CEO
