INCENTIVE STOCK OPTION AGREEMENT

WITH TANDEM SAR

Granted [INSERT AWARD DATE]

This Incentive Stock Option Agreement with Tandem SAR (“Agreement”) is entered into as of [INSERT AWARD DATE] pursuant to the 2004 Incentive Stock Plan (the “Plan”) of Pinnacle Bankshares Corporation, a Virginia corporation (the “Company”), and evidences the grant of an Option and Tandem SAR (as defined in the Plan), and the terms, conditions and restrictions pertaining thereto, to «name» (the “Employee”).

1. Award of Shares. Pursuant to the Plan, effective on [INSERT AWARD DATE] (the “Award Date”), the Company awarded to the Employee the right and option to purchase (the “Award”), upon the terms and conditions hereinafter set forth, all or any part of a total of «number» of shares of the Company’s Stock at the Option Price of $«price» per share.

2. Time and Limitations on Exercise of Option. This Option shall not be exercisable after [INSERT OPTION EXPIRATION DATE]; provided, however, that this Option may be terminated earlier as provided below. In addition and except as provided in Paragraph 6 below, this Option shall first be exercisable [INSERT VESTING DATE/SCHEDULE] (e.g., the Employee will not be able to exercise this Option [INSERT VESTING DATE/SCHEDULE]). In addition, this Option may only be exercised for whole shares of the Company’s Stock.

3. Conditions of Exercise of Option During Employee’s Lifetime. During the Employee’s lifetime, this Option may be exercised only by him, and then only if the Employee has been an employee of the Company or one or more of its Subsidiaries continuously from the Award Date to the date of exercise; provided, however, that if the Employee or the Company terminates his employment for any reason (including termination because of retirement or permanent and total disability), the Employee shall be entitled to exercise this Option only to the extent it was exercisable by the Employee at the date of such termination of employment, and further provided that this Option shall not be exercisable more than twelve (12) months after such termination of employment. The Board of Directors of the Company, or a committee thereof, reserves the right, however, to extend this twelve month period up to two years after the date of termination of employment (but not beyond [INSERT OPTION EXPIRATION DATE]). Notwithstanding the foregoing, the Company reserves the right to terminate and declare forfeited all or any unexercised portion of this Option held by the Employee in the event (i) his employment is terminated as a result of any illegal act or intentional act evidencing bad faith by the Employee toward the Company or one of its Subsidiaries or (ii) during the period this Option remains exercisable following termination of his employment for any reason, whether such termination was voluntary or involuntary, the Employee accepts employment with or provides services to a company or organization that, in the sole discretion of the Company, competes with the Company or any Subsidiary or affiliate of the Company.

4. Option Nontransferable during Employee’s Lifetime; Conditions of Exercise After Employee’s Death. This Option shall not be transferable by the Employee other than by his will or by the laws of descent and distribution. If the employment of the Employee terminates by death while in the employ of the Company or a Subsidiary, then this Option may be exercised at any time during the three (3) year period following the Employee’s date of death, to the extent that the Employee was entitled to exercise this Option on the date of his death, by the person or persons to whom the Employee’s rights under this Option shall pass by will or by applicable law. In no event may this Option be exercised after the expiration date specified in Paragraph 1.

5. Method of and Effective Date of Exercising Option. This Option may be exercised from time to time on any business day upon delivery to the Company of (a) a Notice of Exercise in the form attached to this Agreement, and (b) payment in full of the Option Price (which Option Price may be paid by the Employee in cash or in shares of Stock of the Company, or in any combination thereof, provided payment of the Option Price, in whole or in part, in shares of Stock of the Company is permitted under applicable state and federal law). No person shall acquire any rights or privileges of a stockholder of the Company with respect to any shares issuable upon such exercise until the effective date of such exercise.

6. Acceleration of Exercise Period. Notwithstanding the limitations set forth in Paragraph 2 above on the exercise of this Option, the Employee may exercise all or any portion of this Option on or after a Transaction Date as defined below, provided this Option shall have been granted not less than six (6) months previously. For purposes of this paragraph, a “Transaction Date” shall mean the date on which an offer or other than the Company shall first publicly offer to acquire shares of Stock of the Company pursuant to a tender offer or exchange offer or the date of mailing of proxy material to the stockholders of the Company with respect to a merger or other reorganization that will result in the Stock of the Company being converted into cash or securities of another entity.

7. Tandem SAR. In connection with the grant of this Option, the Employee is also granted a Tandem SAR with this Option, which Tandem SAR may be exercisable in lieu of all or part of this Option (to the extent exercisable at the time in question). The number of shares of the Company’s Stock to which the Tandem SAR pertains shall be equal to the number of shares of the Company’s Stock subject to this Option, determined as of the date the Tandem SAR is exercised. The Tandem SAR shall have an exercise price per share equal to the Option Price per share of Stock to which it pertains. The Tandem SAR granted hereunder shall be exercisable, in whole or in part, at the same time and to the same extent as this Option. Any exercise of the Tandem SAR shall reduce the number of shares of the Company’s Stock subject to this Option by the number of shares with respect to which the Tandem SAR is exercised. Upon any exercise of the Tandem SAR, the Employee shall receive from the Company that number of shares of the Company’s Stock equal to the product determined by dividing (a) the product obtained by multiplying (i) the excess of (A) the Fair Market Value per share of the Stock on the date of exercise over (B) the Tandem SAR exercise price by (ii) the number of shares of Stock with respect to which the Tandem SAR is exercised as of the date of exercise, by (b) the Fair Market Value per share of the Stock on the date of exercise. In the event the amount determined in (a) exceeds the product of the Fair Market Value per share of the Stock on the date of exercise multiplied by the number of shares of Stock issued on the exercise of the Tandem SAR, the excess shall immediately be paid in cash to the Employee.

8. Capital Adjustments. The number of shares of Stock of the Company covered by this Option and the Tandem SAR herein, and the Option Price and Tandem SAR exercise price thereof, will be subject to an appropriate and equitable adjustment as determined by the Committee as provided in Section 4.3 of the Plan.

9. Prohibition Against Pledge, Attachment, etc. Except as otherwise herein provided, this Option and the Tandem SAR herein and the rights and privileges conferred hereby shall not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process.

10. Administration of Plan. The Plan is administered by the Committee appointed by the Company’s Board of Directors. The Committee has the authority to construe and interpret the Plan, to make rules of general application relating to the Plan, to amend outstanding awards pursuant to the Plan, and to require of any person receiving an award, at the time of such receipt or lapse of restrictions, the execution of any paper or the making of any representation or the giving of any commitment that the Committee shall, in its discretion, deem necessary or advisable by reason of the securities laws of the United States or any State, or the execution of any paper or the payment of any sum of money in respect of taxes or the undertaking to pay or have paid any such sum that the Committee shall in its discretion, deem necessary by reason of the Code or any rule or regulation thereunder, or by reason of the tax laws of any State.

11. Plan and Prospectus. This Option and the Tandem SAR herein are granted pursuant to the Plan and are subject to the terms thereof (including all applicable vesting, forfeiture, settlement and other provisions). A copy of the Plan, as well as a prospectus for the Plan, has been provided to the Employee, and the Employee acknowledges receipt thereof.

12. Withholding Taxes. The Company, or any of its Subsidiaries, shall have the right to withhold any federal, state or local taxes required to be withheld by law with respect to the exercise of this Option (including exercise of the Tandem SAR herein). The Committee may require the Employee or any successor in interest to pay or reimburse the Company, or any of its Subsidiaries, for any such taxes required to be withheld by the Company, or any of its Subsidiaries, and to withhold any distribution in whole or in part until the Company, or any of its Subsidiaries, is so paid or reimbursed. In lieu thereof, the Company, or any of its Subsidiaries, shall have the right to withhold from any other cash amounts due to or to become due from the Company, or any of its Subsidiaries, to or with respect to the Employee an amount equal to such taxes required to be withheld by the Company, or any of its Subsidiaries, to pay or reimburse the Company, or any of its Subsidiaries, for any such taxes or to retain and withhold a number of shares of the Company’s Stock having a Fair Market Value not less than the amount required to be withheld and cancel any such shares so withheld in order to pay or reimburse the Company, or any of its Subsidiaries, for any such taxes. The Employee or any successor in interest is authorized to deliver shares of the Company’s Stock in satisfaction of minimum statutorily required tax withholding obligations (whether or not such shares have been held for more than six months and including shares acquired pursuant to this Award if the restrictions thereon have lapsed).

13. Incentive Stock Option. This Option is intended to qualify as an incentive stock option (an ISO as defined in the Plan) within the meaning of Section 422(b) of the Code, and the provisions hereof shall be construed consistent with that intent. If this Option fails or ceases to qualify as an incentive stock option within the meaning of Section 422(b) of the Code, it shall continue in effect as a Non-qualified Stock Option.

14. Construction and Capitalized Terms. This Agreement shall be administered, interpreted and construed in accordance with the applicable provisions of the Plan. Capitalized terms in this Agreement have the meaning assigned to them in the Plan, unless this Agreement provides, or the context requires, otherwise.

15. Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the Commonwealth of Virginia.

16. Successors. This Agreement shall be binding upon and inure to the benefit of the successors, assigns, heirs and legal representatives of the respective parties.

17. Entire Agreement. This Agreement contains the entire understanding of the parties and shall not be modified or amended except in writing signed by the parties.

18. Severability. The various provisions of this Agreement are severable in their entirety. Any determination of invalidity or unenforceability of any one provision shall have no effect on the continuing force and effect of the remaining provisions.

To evidence their agreement to the terms, conditions and restrictions hereof, the Company and the Employee have signed this Agreement as of the date first above written.
