Ladies and Gentlemen:

The undersigned, having received and read your prospectus dated November ___, 2011 (the “Prospectus”), understand that as shareholders of Chino Commercial Bancorp (the “Company”) as of November 18, 2011, they are being given basic subscription rights entitling them to subscribe for up to the number of shares of the Company’s common stock shown above, at a subscription price of $_______ per share.  Persons exercising these subscription rights will also receive bonus shares equal to five percent (5%) of the number of shares purchased pursuant to such rights, for no additional consideration.  The undersigned further understand that if and only if they fully exercise their basic subscription rights, they are also being given an over-subscription privilege allowing them to subscribe for an unlimited number of additional shares (up to the total number of shares offered) on the same basis (i.e., with the bonus shares attached), subject to availability.  The precise number of shares subject to the over-subscription privilege cannot be determined until it is known how many shares remain available after the exercise of all shareholders’ basic subscription rights.  If sufficient shares of common stock are available, over-subscription requests will be honored in full.  If over-subscription requests exceed the number of shares available, the available shares of common stock among rights holders who exercise their over-subscription privileges will be allocated by the Company on a discretionary basis, after giving consideration to both the number of shares each rights holder subscribed for under his or her basic subscription rights and the number of shares requested through the exercise of the over-subscription privilege.  The basic subscription right and the over-subscription privilege are referred to collectively as the “subscription rights.”  For more information concerning the subscription rights, please refer to the Prospectus.

In addition, the undersigned understand that they may subscribe for any number of shares being offered on a non-rights basis, at the same subscription price of $_______ per share.  However, investors purchasing shares in the non-rights portion of the offering will not receive any “bonus” shares in connection with their purchases.  Management of the Company, in its sole discretion, may elect not to offer shares in connection with this offering to any person (including a shareholder) who is not a resident of California.
