---------------------------------------------------
DETERMINATION OF REVISED SUBSCRIPTION PRICE
---------------------------------------------------
The revised subscription price for the shares of common stock was
determined by management and approved by the North Bay Board of Directors based
upon information which they believed to be relevant, including an opinion from
its financial advisors that the $22.00 revised subscription price is fair to the
existing holders of North Bay. Management and the Board also considered the
recent trading history of the common stock, North Bay's and Vintage Bank's
financial condition and earnings as well as the per share book value of the
common stock.
The primary objectives in establishing the revised subscription price
were to maximize net proceeds obtainable from the offering and to enhance the
success of the offering.
No assurance can be given that the market price of North Bay's common
stock will not decline during the offering to a level below the subscription
price or that a shareholder will be able to sell shares purchased in the
offering at a price equal to or greater than the subscription price.
Opinion of Financial Advisor
North Bay's Board of Directors retained Hoefer & Arnett, Incorporated
as its financial advisor to assist it in establishing the revised subscription
price. On March 28, 2000, Hoefer & Arnett delivered its oral opinion to North
Bay's Board of Directors that the revised subscription price was fair, from a
financial point of view, to the shareholders of North Bay. On March 29, 2000,
Hoefer & Arnett delivered its written opinion to North Bay confirming its oral
opinion. North Bay did not impose any limitations on Hoefer & Arnett with
respect to its opinion.
Hoefer & Arnett is a nationally recognized investment banking firm and,
as part of its investment banking activities, is regularly engaged in the
valuation of businesses and their securities in connection with merger
transactions and other types of acquisitions, negotiated underwritings, private
placements and valuations for corporate and other purposes. North Bay selected
Hoefer & Arnett to render the opinion on the basis of its experience and
expertise and its reputation in the banking and investment communities.
In rendering its opinion in connection with the offering, Hoefer &
Arnett relied upon information and materials provided by North Bay. In addition,
Hoefer & Arnett met with the directors and management of North Bay and reviewed
other data relating to the economics for the relevant area and conducted tests
of the market value of North Bay common stock. Hoefer & Arnett also reviewed
drafts of this prospectus, compared North Bay from a financial point of view
with other selected companies in the financial services industry, and considered
other information that it considered appropriate. Hoefer & Arnett has not
independently verified the information and documents provided by the directors
and management of North Bay.
Hoefer & Arnett was paid a fee in the amount of $4,000 in connection
with its advisory services to North Bay, including the preparation of its
opinion and report.

investigation to ascertain the matters required by law, including that (a) the
proposed Bank would promote the public convenience and advantage; (b) the
proposed capital structure is adequate; and (c) the conditions in Solano County,

officers, afford a reasonable promise of successful operations. This
determination by the Commissioner does not constitute a representation or
guarantee by him that Solano Bank will be successful. Final licensing of Solano
Bank to commence operations is dependent upon compliance with certain conditions
and procedures under California law, including completion of this offering and
Solano Bank obtaining Federal Deposit Insurance and becoming a member of the
Federal Reserve System. From May 3, 2000 until final licensing, the new bank
