WHEREAS, the parties desire to enter into this Agreement in order to clearly set forth the terms and conditions of the Officer’s employment relationship with the Corporation; and

WHEREAS, prior to this Agreement, the parties entered into a Severance Agreement (the “Severance Agreement”), which sets forth certain rights and obligations of the Officer and certain rights and obligations of the Corporation in the event of a “Potential Change of Control” (as defined in the Severance Agreement) or following a “Change in Control” (as defined in the Severance Agreement). Use of the phrases “Potential Change of Control” and “Change in Control” herein shall have the meanings ascribed to those phrases in the Severance Agreement.

NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained, the parties hereby agree as follows:

1. Employment. The Corporation hereby employs the Officer and the Officer hereby accepts such employment, upon the terms and conditions stated herein, as Senior Vice President – General Counsel, Corporate Secretary & Chief Compliance & Community Affairs Officer of the Corporation. The Officer shall render such administrative and management services to the Corporation as are customarily performed by persons situated in a similar executive capacity. The Officer shall promote the business of the Corporation and perform such other duties as shall from time to time be reasonably prescribed by the Directors or the Chief Executive Officer of the Corporation. It is understood that the Officer’s continued election as an officer of the Corporation is

dependent upon action by the Board of Directors of the Corporation from time to time and that, subject to the provisions of Section 7 of this Agreement, the Officer’s title and/or duties may change from time to time; provided that following a Change in Control and during the term of the Severance Agreement any action affecting a change in title and/or duties shall be subject to the Severance Agreement.

2. Base Salary. The Corporation shall pay the Officer during the term of this Agreement as compensation for all services rendered by her to the Corporation a base salary in such amounts and at such intervals as shall be commensurate with her duties and responsibilities hereunder. Initially such base salary shall be at the rate of $326,000 per year. The Officer’s base salary may be increased from time to time to reflect the duties required of the Officer. In reviewing the Officer’s base salary, the Board of Directors of the Corporation shall consider the overall performance of the Corporation, the overall performance of the Officer and the service of the Officer rendered to the Corporation and its subsidiaries and changes in the cost of living. The Board of Directors may also provide for performance or merit increases. Participation by Officer in any incentive, deferred compensation, stock option, stock purchase, bonus, pension, life insurance or other employee benefit plans which may be offered by the Corporation from time to time and participation in any fringe benefits provided by the Corporation shall not cause a reduction of the base salary payable to the Officer. The Officer will be entitled to such customary fringe benefits, vacation and sick leave as are consistent with the normal practices and established policies of the Corporation.

3. Participation in Incentive, Retirement and Employee Benefit Plans; Fringe Benefits. The Officer shall be entitled to participate in any plan relating to incentive compensation, stock options, stock purchase, pension, thrift, profit sharing, group life insurance, medical coverage, disability coverage, education, or other retirement or employee benefits that the Corporation has adopted, or may from time to time adopt, for the benefit of its executive employees and for employees generally, subject to the eligibility rules of such plans.

The Officer shall also be entitled to participate in any other fringe benefits which are now or may be or become applicable to the Corporation’s executive employees, including the payment of reasonable expenses for attending annual and periodic meetings of trade associations, and any other benefits which are commensurate with the duties and responsibilities to be performed by the Officer under this Agreement. Additionally, the Officer shall be entitled to such vacation and sick leave as shall be established under uniform employee policies promulgated by the Board of Directors. The Corporation shall reimburse the Officer for all out-of-pocket reasonable and necessary business expenses which the Officer may incur in connection with her service on behalf of the Corporation.

4. Term. The initial term of employment under this Agreement shall be for a one-year period commencing August 1, 2011; provided that this Agreement shall automatically be extended to a full one-year period on each successive day during the term of this Agreement. The effect hereof shall be that the Agreement shall at all times remain subject to a term of one year, unless (i) written notice has been given that the Agreement shall not be extended as provided in this Section 4, or (ii) the Agreement is terminated pursuant to Section 7. If written notice from the Corporation or the Officer is delivered to the other party advising the other party that this Agreement is not to be further extended, then upon such notice, the Agreement shall terminate on the anniversary of the

date of notice. Provided, further, no extension shall cause this Agreement to extend beyond the date on which the Officer reaches 65 years of age. Upon any extension, the base salary of the extended agreement shall be the base salary in effect on the effective date of such extension.

9. Code Section 409A.

(a) Delay of Certain Payments. Notwithstanding anything in this Agreement to the contrary, if any amount or benefit that the Company determines would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Internal Revenue Code of 1986 (the “Code”) would otherwise be payable or distributable under this Agreement by reason of the Officer’s termination of employment, then to the extent necessary to comply with Code Section 409A:

(i) if the payment or distribution is payable in a lump sum, the Officer’s right to receive payment or distribution of such non-exempt deferred compensation will be delayed until the earlier of the Officer’s death or the seventh month following the Officer’s termination of employment; and

(ii) if the payment or distribution is payable over time, the amount of such non-exempt deferred compensation that would otherwise be payable during the six (6) month period immediately following the Officer’s termination of employment will be accumulated and the Officer’s right to receive payment or distribution of such accumulated amount will be delayed until the earlier of the Officer’s death or the seventh month following the Officer’s termination of employment and paid on the earlier of such dates, without interest, and the normal payment or distribution schedule for any remaining payments or distributions will commence.

(b) Expense Reimbursements. To the extent any expense reimbursement or in-kind benefit to which the Officer is or may be entitled to receive under this Agreement constitutes non-exempt “deferred compensation” for purposes of Section 409A of the Code, then (i) such reimbursement shall be paid to the Officer as soon as administratively practicable after the Officer submits a valid claim for reimbursement, but in no event later than the last day of the Officer’s taxable year following the taxable year in which the expense was incurred, (ii) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during any taxable year of the Officer shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year of the Officer, and (iii) the Officer’s right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit.

10. Modification; Waiver; Amendments.

No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time.
