THIS NON-QUALIFIED STOCK
OPTION AGREEMENT (the Agreement) is made as of this       day of
                        ,
between Princeton National Bancorp, Inc., a Delaware corporation (the Company), and(the Optionee).

WHEREAS, the Company wishes
to align the interests of the Optionee with those of shareholders;

WHEREAS, on
                        ,
(the Grant Date), the Companys Board of Directors granted non-qualified stock options to certain employees of
the Company and its Subsidiaries, including the Optionee; and

WHEREAS, the parties desire
to document the terms of stock option grants;

NOW THEREFORE, the parties
agree as follows:

1.       Grant
of Options.   The Company has granted
                 Non-Qualified Stock Options to
the Optionee (the Options). Each Option is exercisable at a price of $        
per share of the Companys Stock (the Option Price).

2.       Vesting
of Options.   The Options are 100% vested and immediately exercisable.

3.       Expiration
of Options.   Unless otherwise determined by the Committee, to the extent not previously exercised, the Options
will expire on the earlier of, (a) the tenth anniversary of the Option Date; (b) three years after the Retirement, Disability or
death of the Optionee; or (c) the termination of employment of the Optionee for reasons other than Retirement, Disability or
death.

4.       Optionee
Rights.   No rights or privileges of a shareholder of the Company are conferred by reason of the granting of
the Options. The Optionee will not become a shareholder of the Company with respect to the Option Stock unless and until the
Options have been properly exercised and the Option Price fully paid for the number of the Options exercised.

---

5.       Transferability.The
Options are not transferable, except by will or the laws of descent and distribution, however, the Directors Personnel, Policy and
Salary Committee (the Committee) has the discretion to allow for other Transfers of Options, but only to the extent
provided in the Plan and only when such Transfer would be considered a completed gift for tax purposes. If an Option is
transferred, it will continue to be subject to the terms and conditions of this Agreement, together with the Plan, and may not be
transferred again. If the Options are transferable during the Optionees lifetime, the Optionee will remain responsible for
all applicable withholding taxes upon the exercise of any transferred Options and will, prior to transferring any Options, notify
the Company of the anticipated Transfer. The Company shall not be required to provide to the transferee any notice of termination
of any of the Options. If the Optionee transfers an Option and dies before a transferred Option has been exercised, the Option
will automatically terminate upon the earlier of one year from the date of the Optionees death or the expiration of the
Option pursuant to this Agreement.

6.       Terms
of Options.   This Agreement, and the Options issued to the Optionee, are subject to all of the terms and
conditions set forth herein and in the Plan, as may be amended from time to time, a copy of which has been provided to Optionee.
To the extent that any conflict may exist between any term or provision of this Agreement and any term or provision of the Plan,
the Plan shall govern. Capitalized terms referenced, but not defined herein, will have the meaning attributed to them by the Plan.
THE OPTIONEE ACKNOWLEDGES THAT HE OR SHE HAS READ THE PLAN AND AGREES TO BE BOUND BY ITS TERMS. Pursuant to the Plan, the
Committee has authorized the Option Price and any applicable tax withholding liability associated with exercise of the Options to
be payable in cash, or by netting or withholding Option Stock granted pursuant to the Options being exercised. In such case, the
Committee may require that Optionee attest to the ownership of shares of Company Stock in a form acceptable to the Committee which
shall include a statement that, at the time of exercise, the shares have been owned by the Optionee for a period of 6 months (or
such other period that the Committee determines appropriate).

7.       Miscellaneous.This
Agreement, together with the Plan, sets forth the complete agreement of the parties concerning the subject matter hereof,
superseding all prior agreements, negotiations and understandings. Nothing contained in this Agreement will confer upon the
Optionee any right with respect to the continuation of his or her employment status with the Company or its Subsidiaries. This
Agreement shall be binding upon, and shall inure to the benefit of, the Company and the Optionee, and their respective heirs,
personal legal representatives and successors. No change or modification of this Agreement shall be valid unless the same is in
writing and signed by the parties hereto; provided, however, that the Optionee hereby covenants and agrees to execute any
amendment to this Agreement which shall be required or desirable (in the opinion of the Company or its counsel) in order to comply
with the laws governing this Agreement. This Agreement will be governed by the substantive law of the State of Illinois and may be
executed in counterparts.
