15. Limitation of Benefits Under Certain Circumstances. If the payments and benefits pursuant to Section 12 of this Agreement, either alone or together with other payments and benefits which Executive has the right to receive from the Company, would constitute a “parachute payment” under Section 280G of the Code, the payments and benefits pursuant to Section 12 shall be reduced or revised, in the manner determined by Executive, by the amount, if any, which is the minimum necessary to result in no portion of the payments and benefits under Section 12 being non-deductible to the Company pursuant to Section 280G of the Code and subject to the excise tax imposed under Section 4999 of the Code. The Company’s independent public accountants shall determine any reduction in the payments and benefits to be made pursuant to Section 12, and the Company shall pay for the accountant’s opinion with respect to such reduction. If the Company and/or Executive do not agree with the accountant’s opinion, the Company shall pay to Executive the maximum amount of payments and benefits pursuant to Section 12, as selected by Executive, which the opinion indicates have a high probability of not causing any of the payments and benefits to be non-deductible to the Company and subject to the imposition of the excise tax imposed under Section 4999 of the Code. The Company may also request, and Executive shall have the right to demand that they request, a ruling from the IRS as to whether the disputed payments and benefits pursuant to Section 12 have such tax consequences.

The request shall also be subject to the Executive’s approval prior to filing; Executive shall not unreasonably withhold her approval. The Company and Executive agree to be bound by any ruling received from the IRS and to make appropriate payments to each other to reflect any IRS rulings, together with interest at the applicable federal rate provided for in Section 7872(f)(2) of the Code. Nothing contained in this Agreement shall result in a reduction of any payments or benefits to which Executive may be entitled upon termination of employment other than pursuant to Section 12 hereof, or a reduction in the payments and benefits specified in Section 12, below zero.

16. Injunctive Relief. Upon a breach or threatened breach of Section 11(g) of this Agreement or the prohibitions upon disclosure contained in Section 10(c) of this Agreement, the parties agree that there is no adequate remedy at law for such breach, and the Company shall be entitled to injunctive relief restraining Executive from such breach or threatened breach, but such relief shall not be the exclusive remedy for a breach of this Agreement. The parties to this Agreement further agree that Executive, without limitation, may seek injunctive relief to enforce the Company’s obligations under this Agreement.

22. Applicable Law. Except to the extent preempted by federal law, Maryland law shall govern this Agreement in all respects, whether as to its validity, construction, capacity, performance or otherwise.

Payments pursuant to this Agreement will be allocated in proportion to the level of activity and the time expended on such activities by Executive as determined by the Company and the Bank.

27. Section 409A of the Code.

(a) This Agreement is intended to comply with the requirements of Section 409A of the Code, and specifically, with the “short-term deferral exception” under Treasury Regulation Section 1.409A-1(b)(4) and the “separation pay exception” under Treasury Regulation Section 1.409A-1(b)(9)(iii), and shall in all respects

9

be administered in accordance with Section 409A of the Code. If any payment or benefit hereunder cannot be provided or made at the time specified herein without incurring sanctions on Executive under Section 409A of the Code, then such payment or benefit shall be provided in full at the earliest time thereafter when such sanctions will not be imposed. For purposes of Section 409A of the Code, all payments to be made upon a termination of employment under this Agreement may only be made upon a “separation from service” (within the meaning of such term under Section 409A of the Code), each payment made under this Agreement shall be treated as a separate payment, the right to a series of installment payments under this Agreement (if any) is to be treated as a right to a series of separate payments, and if a payment is not made by the designated payment date under this Agreement, the payment shall be made by December 31 of the calendar year in which the designated date occurs. To the extent that any payment provided for hereunder would be subject to additional tax under Section 409A of the Code, or would cause the administration of this Agreement to fail to satisfy the requirements of Section 409A of the Code, such provision shall be deemed null and void to the extent permitted by applicable law, and any such amount shall be payable in accordance with b. below. In no event shall Executive, directly or indirectly, designate the calendar year of payment.

(b) If when separation from service occurs Executive is a “specified employee” within the meaning of Section 409A of the Code, and if the cash severance payment under Section 11(f)(ii) or 12(b) would be considered deferred compensation under Section 409A of the Code, and, finally, if an exemption from the six-month delay requirement of Section 409A(a)(2)(B)(i) of the Code is not available (i.e., the “short-term deferral exception” under Treasury Regulations Section 1.409A-1(b)(4) or the “separation pay exception” under Treasury Section 1.409A-1(b)(9)(iii)), the Bank will make the maximum severance payment possible in order to comply with an exception from the six month requirement and make any remaining severance payment under Section 11(f)(ii) or 12(b) to Executive in a single lump sum without interest on the first payroll date that occurs after the date that is six (6) months after the date on which Executive separates from service.

(c) If (x) under the terms of the applicable policy or policies for the insurance or other benefits specified in Section 11(f)(ii) or 12(b) it is not possible to continue coverage for Executive and her dependents, or (y) when a separation from service occurs Executive is a “specified employee” within the meaning of Section 409A of the Code, and if any of the continued insurance coverage or other benefits specified in Section 11(f)(ii) or 12(b) would be considered deferred compensation under Section 409A of the Code, and, finally, if an exemption from the six-month delay requirement of Section 409A(a)(2)(B)(i) of the Code is not available for that particular insurance or other benefit, the Bank shall pay to Executive in a single lump sum an amount in cash equal to the present value of the Bank’s projected cost to maintain that particular insurance benefit (and associated income tax gross-up benefit, if applicable) had Executive’s employment not terminated, assuming continued coverage for 36 months. The lump-sum payment shall be made thirty (30) days after employment termination or, if Section 27(b) applies, on the first payroll date that occurs after the date that is six (6) months after the date on which Executive separates from service.

(d) References in this Agreement to Section 409A of the Code include rules, regulations, and guidance of general application issued by the Department of the Treasury under Internal Revenue Section 409A of the Code.
