Other Early Termination.  In the event of a voluntary Separation from Service for Good Reason, or in the event of an involuntary Separation from Service for reasons other than for Cause prior to the Full Vesting Date, the Executive and the Spouse will be eligible to receive the full benefit defined in Sections 4.1 and 4.2.

Change in Control.  In the event the Executive is involuntarily Separated from Service following a Change in Control, or in the event that the Executive voluntary Separates from Service  for Good Reason following a Change in Control, the Executive and the Spouse will be eligible to receive the full benefits defined in Sections 4.1 and 4.2, beginning as of the later of (i) the first day of the seventh month after Separation from Service, or (ii) the Full Vesting Date

Commencement of Payments.  Payment of any benefits provided under this Article IV shall commence within 90 days of the later of Separation from Service or the attainment of the Full Vesting Date; provided, however, that if the Executive is a Specified Employee as of the date he incurs a Separation from Service, payment of benefits that are payable upon Separation from Service will be made or begin on the earlier of (i) the first day of the seventh month following the month in which such Separation from Service occurs or (ii) the death of the Executive. Subsequent annual payments shall be made on the anniversary date of the operative payment event.

Withholding; Payroll Taxes.  The Company shall withhold from payments hereunder any taxes required to be withheld from such payments under local, state or federal law. The Executive and/or the Spouse may elect not to have withholding of federal income tax pursuant to Section 3405(a)(2) of the Code, or any successor provision thereto.

Payment to Guardian.  If a Plan benefit is payable to a minor or a person declared incompetent or to a person incapable of handling the disposition of property, the Committee may direct payment to the guardian, legal representative or person having the care and custody of such minor, incompetent or person.  The Committee may require proof of incompetency, minority, incapacity or guardianship as it may deem appropriate prior to distribution. Such distribution shall completely discharge the Committee and Company from all liability with respect to such benefit.

Payments Following Death of Executive and the Spouse. No payments shall be made to any person, trust or entity under this Plan after the death of the Executive and the Spouse. No benefits shall be payable under the Plan to anyone other than the Executive and the Spouse (as specifically identified by name in Article I), or their respective guardians, in the event of physical or mental disability.

Committee; Duties.  The Plan shall be administered by the Committee.  The Committee shall have the authority to make, amend, interpret, and enforce all appropriate rules and regulations for the administration of the Plan and decide or resolve any and all questions, including

interpretations of the Plan, as may arise in such administration.  A majority vote of the Committee members shall control any decision.

Agents.  The Committee may, from time to time, employ agents and delegate to them such administrative duties as it sees fit, and may from time to time consult with counsel who may be counsel to the Company.

Binding Effect of Decisions.  The decision or action of the Committee with respect to any question arising out of or in connection with the administration, interpretation and application of the Plan and the rules and regulations promulgated hereunder shall be final, conclusive and binding upon all persons having any interest in the Plan.

Indemnity of Committee.  The Company shall indemnify and hold harmless the members of the Committee against any and all claims, loss, damage, expense or liability arising from any action or failure to act with respect to this Plan on account of such member's service on the Committee, except in the case of gross negligence or willful misconduct.

General Assets.  All benefits in respect of the Executive under this Plan shall be paid directly from the general funds of the Company or a rabbi trust created for the purpose of informally funding the Plan, and other than such rabbi trust, if created, no special or separate fund shall be established and no other segregation of assets shall be made to assure payment.  Neither the Executive nor the Spouse shall have any right, title or interest whatever in or to any investments that the Company may make to aid the Company in meeting its obligation hereunder.  Nothing contained in this Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship, between the Company and the Executive or the Spouse.  To the extent that any person acquires a right to receive payments from the Company hereunder, such rights are no greater than the right of an unsecured general creditor of the Participating Employer.

Rabbi Trust.  The Company may, at its sole discretion, establish a grantor trust, commonly known as a rabbi trust, as a vehicle for accumulating the assets needed to pay the promised benefit, but the Company shall be under no obligation to establish any such trust or any other informal funding vehicle.

Filing a Claim. Any controversy or claim arising out of or relating to the Plan shall be filed with the Committee which shall make all determinations concerning such claim. Any

decision by the Committee denying such claim shall be in writing and shall be delivered to the Executive or Spouse filing the claim (“Claimant”).

In General.  Notice of a denial of benefits will be provided within 90 days of the Committee’s receipt of the Claimant's claim for benefits. If the Committee determines that it needs additional time to review the claim, the Committee will provide the Claimant with a notice of the extension before the end of the initial 90-day period. The extension will not be more than 90 days from the end of the initial 90-day period and the notice of extension will explain the special circumstances that require the extension and the date by which the Committee expects to make a decision.

Contents of Notice.  If a claim for benefits is completely or partially denied, notice of such denial shall be in writing and shall set forth the reasons for denial in plain language. The notice shall (1) cite the pertinent provisions of the Plan document and (2) explain, where appropriate, how the Claimant can perfect the claim, including a description of any additional material or information necessary to complete the claim and why such material or information is necessary. The claim denial also shall include an explanation of the claims review procedures and the time limits applicable to such procedures, including a statement of the Claimant’s right to bring a civil action under Section 502(a) of ERISA following an adverse decision on review.

Appeal of Denied Claims. A Claimant whose claim has been completely or partially denied shall be entitled to appeal the claim denial by filing a written appeal with the Board. A Claimant who timely requests a review of the denied claim (or his or her authorized representative) may review, upon request and free of charge, copies of all documents, records and other information relevant to the denial and may submit written comments, documents, records and other information relevant to the claim to the Board.  All written comments, documents, records, and other information shall be considered “relevant” if the information (1) was relied upon in making a benefits determination, (2) was submitted, considered or generated in the course of making a benefits decision regardless of whether it was relied upon to make the decision, or (3) demonstrates compliance with administrative processes and safeguards established for making benefit decisions. The Board may, in its sole discretion and if it deems appropriate or necessary, decide to hold a hearing with respect to the claim appeal.

In General. Appeal of a denied benefits claim must be filed in writing with the Board no later than sixty (60) days after receipt of the written notification of such claim denial.  The Board shall make its decision regarding the merits of the denied claim within sixty (60) days following receipt of the appeal (or within one hundred and twenty (120) days after such receipt, in a case where there are special circumstances requiring extension of time for reviewing the appealed claim).  If an extension of time for reviewing the appeal is required because of special circumstances, written notice of the extension shall be furnished to the Claimant prior to the commencement of the extension. The notice will indicate the special

circumstances requiring the extension of time and the date by which the Board expects to render the determination on review.  The review will take into account comments, documents, records and other information submitted by the Claimant relating to the claim without regard to whether such information was submitted or considered in the initial benefit determination.  

Contents of Notice. If a benefits claim is completely or partially denied on review, notice of such denial shall be in writing and shall set forth the reasons for denial in plain language. The decision on review shall set forth (a) the specific reason or reasons for the denial, (b) specific references to the pertinent Plan provisions on which the denial is based, (c) a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to and copies of all documents, records, or other information relevant (as defined above) to the Claimant’s claim, and (d) a statement describing any voluntary appeal procedures offered by the plan and a statement of the Claimant’s right to bring an action under Section 502(a) of ERISA.

Legal Action.  A Claimant may not bring any legal action relating to a claim for benefits under the Plan unless and until the Claimant has followed the claims procedures under the Plan and exhausted his or her administrative remedies under such claims procedures.

Discretion of Committee.  All interpretations, determinations and decisions of the Committee with respect to any claim shall be made in its sole discretion, and shall be final and conclusive.

Termination, Suspension or Amendment of Plan.  The Company may not terminate, amend or suspend the Plan at any time, in whole or in part, unless such action is done with the written consent of the Executive and the Spouse, if living.

Non-assignability.  Neither the Executive nor the Spouse shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise encumber, transfer, hypothecate or convey in advance of actual receipt the amounts, if any, payable hereunder, or any part thereof, which are, and all rights to which are, expressly declared to be unassignable and nontransferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure or sequestration for the payment of any debts, judgments, alimony or separate maintenance owed by the Executive or the Spouse or any other person, nor be transferable by operation of law in the event of the Executive’s, the Spouse’s, or any other person's bankruptcy or insolvency.

Not a Contract of Employment.  This Plan shall not constitute a contract of employment between Company and the Executive.  Nothing in this Plan shall give the Executive the right to be retained in the service of Company or to interfere with the right of Company to discipline or discharge the Executive at any time.

Protective Provisions.  The Executive shall cooperate with Company by furnishing any and all information requested by Company in order to facilitate the payment of benefits hereunder, and by taking such physical examinations as Company may deem necessary and by taking such other action as may be requested by Company.

Governing Law.  The provisions of this Plan shall be construed and interpreted according to the laws of the Commonwealth of Virginia except as preempted by federal law.

Validity.  If any provision of this Plan shall be held illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts hereof, but this Plan shall be construed and enforced as if such illegal and invalid provision had never been inserted herein.

Notice.  Any notice or filing required or permitted under the Plan shall be sufficient if in writing and hand delivered or sent by registered or certified mail.  Such notice shall be deemed given as of the date of delivery or, if delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification.  Mailed notice to the Committee shall be directed to the Company's address.  Mailed notice to the Executive or the Spouse shall be directed to the individual's last known address in Company's records.

Successors.  The provisions of this Plan shall bind and inure to the benefit of Company and its successors and assigns.

The Executive understands and agrees that the Company makes no representations as to the tax consequences of any benefits provided hereunder (including, without limitation, under Section 409A of the Internal Revenue Code).  The Executive (or the Executive’s Spouse) is solely responsible for any and all income, excise

or other taxes imposed on the Executive or the Spouse with respect to any benefits provided hereunder.
