MANAGEMENT CONTINUITY AGREEMENT

Exhibit 10.6

MANAGEMENT CONTINUITY AGREEMENT

This Agreement (“Agreement”), dated as of December 16, 2005, is between Union Bankshares Corporation, a Virginia corporation (the “Company”), and Rawley H. Watson, III (the “Executive”) and provides as follows.

The Company recognizes that the possibility of a Change in Control exists and the uncertainty and questions that it may raise among management may result in the departure or distraction of management personnel to the detriment of the Company and its shareholders. Accordingly, the purpose of this Agreement is to encourage the Executive to continue employment after a Change in Control by providing reasonable employment security to the Executive and to recognize the prior service of the Executive in the event of a termination of employment under certain circumstances after a Change in Control.

This Agreement will be effective on December 16, 2005 and will expire on December 31, 2006; provided that on January 1, 2006 and on each January 1 ^st thereafter (each such January 1 ^st is referred to as the “Renewal Date”), this Agreement will be automatically extended for an additional calendar year. This Agreement will not, however, be extended if the Company gives written notice of such non-renewal to the Executive no later than September 30 ^th before the Renewal Date, provided, however, that the Company shall not have the right to give any such non-renewal notice if a Change in Control of the Company (as defined in Section 12) has occurred (the original and any extended term of this Agreement is referred to as the “Change in Control Period”).

If a Change in Control of the Company (as defined in Section 12) occurs during the Change in Control Period and the Executive is employed by the Company on the date the Change in Control occurs (the “Change in Control Date”), the Company will continue to employ the Executive in accordance with the terms and conditions of this Agreement for the period beginning on the Change in Control Date and ending on the third anniversary of such date (the “Employment Period”). If a Change in Control occurs on account of a series of transactions, the Change in Control Date is the date of the last of such transactions.

(a) Position and Duties . During the Employment Period, (i) the Executive’s position, authority, duties and responsibilities will be commensurate in all material respects with the most significant of those held, exercised and assigned at any time during the 90-day period immediately preceding the Change in Control Date and (ii) the Executive’s services will be performed at the location where the Executive was employed immediately preceding

the Change in Control Date or any office that is the headquarters of the Company and is less than 35 miles from such location.

(b) Compensation .

(i) Base Salary . During the Employment Period, the Executive will receive an annual base salary (the “Annual Base Salary”) at least equal to the base salary paid or payable to the Executive by the Company and its affiliated companies for the twelve-month period immediately preceding the Change of Control Date. During the Employment Period, the Annual Base Salary will be reviewed at least annually and will be increased at any time and from time to time as will be substantially consistent with increases in base salary generally awarded in the ordinary course of business to other peer executives of the Company and its affiliated companies. Any increase in the Annual Base Salary will not serve to limit or reduce any other obligation to the Executive under this Agreement. The Annual Base Salary will not be reduced after any such increase, and the term Annual Base Salary as used in this Agreement will refer to the Annual Base Salary as so increased. The term “affiliated companies” includes any company controlled by, controlling or under common control with the Company.

(ii) Annual Bonus . In addition to the Annual Base Salary, the Executive will be awarded for each year ending during the Employment Period an annual bonus (the “Annual Bonus”) in cash at least equal to the average annual bonus paid or payable, including by reason of any deferral, for the two years immediately preceding the year in which the Change in Control Date occurs. Each such Annual Bonus will be paid no later than the end of the third month of the year next following the year for which the Annual Bonus is awarded.

(iii) Incentive, Savings and Retirement Plans . During the Employment Period, the Executive will be entitled to participate in all incentive (including stock incentive), savings and retirement, insurance plans, policies and programs applicable generally to other peer executives of the Company and its affiliated companies, but in no event will such plans, policies and programs provide the Executive with incentive opportunities, savings opportunities and retirement benefit opportunities, in each case, less favorable, in the aggregate, than those provided by the Company and its affiliated companies for the Executive under such plans, policies and programs as in effect at any time during the six months immediately preceding the Change in Control Date.

(iv) Welfare Benefit Plans . During the Employment Period, the Executive and/or the Executive’s family, as the case may be, will be eligible for participation in and will receive all benefits under welfare benefit plans, policies and programs provided by the Company and its affiliated companies to the extent applicable generally to other peer executives of the Company and its affiliated companies, but in no event will such plans, policies and programs provide the Executive with benefits that are less favorable, in the aggregate, than the most

(v) Fringe Benefits . During the Employment Period, the Executive will be entitled to fringe benefits in accordance with the most favorable plans, policies and programs of the Company and its affiliated companies in effect for the Executive at any time during the six months immediately preceding the Change in Control Date or, if more favorable to the Executive, as in effect generally from time to time after the Change in Control Date with respect to other peer executives of the Company and its affiliated companies.

(vi) Vacation . During the Employment Period, the Executive will be entitled to paid vacation in accordance with the most favorable plans, policies and programs of the Company and its affiliated companies in effect for the Executive at any time during the six months immediately preceding the Change in Control Date or, if more favorable to the Executive, as in effect generally from time to time after the Change in Control Date with respect to other peer executives of the Company and its affiliated companies.

(a) Death or Disability . The Executive’s employment will terminate automatically upon the Executive’s death during the Employment Period.

(b) Cause . The Company may terminate the Executive’s employment during the Employment Period for Cause. For purposes of this Agreement, “Cause” means (i) gross incompetence, gross negligence, willful misconduct in office or breach of a material fiduciary duty owed to the Company or any affiliated company; (ii) conviction of a felony or a crime of moral turpitude (or a plea of nolo contendere thereto) or commission of an act of embezzlement or fraud against the Company or any affiliated company; (iii) any material breach by the Executive of a material term of this Agreement, including, without limitation, material failure to perform a substantial portion of his duties and responsibilities hereunder; or (iv) deliberate dishonesty of the Executive with respect to the Company or any affiliated company.

(c) Good Reason; Window Period . The Executive’s employment may be terminated (i) during the Employment Period by the Executive for Good Reason or (ii) during the Window Period by the Executive without any reason.
