 (1) To compute and certify the amounts payable to Participants and their Beneficiaries;

 (2) To maintain or to designate any person or entity to maintain all records necessary for the administration of the Plan;

 (3) To make and publish such rules for the Plan as are not inconsistent with the terms hereof; and 

(4) To provide for disclosure of such information, including reports and statements to Participants or Beneficiaries, and to provide for
the making of applications and elections by Participants under the Plan as may be required by the Plan or otherwise deemed appropriate by the Committee 
 Notwithstanding the above, no person who serves on the Committee shall participate in any matter which involves solely a determination of the benefits payable to him or her under the Plan. Any action of
the Committee with respect to the Plan shall be conclusive and binding upon all Participants and Beneficiaries except to the extent otherwise specifically indicated herein. The Committee may appoint agents and delegate thereto such powers and duties
in connection with the administration of the Plan as the Committee may from time to time prescribe. 
 (b) Annual

and his or her Cash Deferral Account as of the end of such Plan Year. 
 SECTION 5. Elections by Participants. 

 (a) Each Participant must irrevocably elect, in accordance with the procedure set forth in Section 3, the following:

 (1) The percentages (up to 100% and in 10% increments) of his or her Annual Fees to be received in the form of Stock (at the
Director Purchase Price on the applicable Fee Payment Date) and in the form of cash; 
 (2) A percentage (up to 100% and in 10%

10% increments) of his or her Annual Fees to be received in the form of cash to be deferred under the Plan and credited to his or her Cash Deferral Account, in accordance with Section 7(a); 

(3) Whether to receive payment of his or her Stock Deferral Account and Cash Deferral Account in the form of (i) a single lump sum
or (ii) substantially equal annual installments for a period not to exceed ten years, subject to the limitations described in Section 8; and 

  
 4 








 (4) Whether payment of his or her Stock Deferral Account and Cash Deferral Account shall be
paid, or commence to be paid, on: 
 (i) the date he ceases to be a Non-Employee Director by reason of his or her
“separation from service” (within the meaning of Treas. Reg. § 1.409A-1(h) or any successor provision) with the Company; 
 (ii) the date that is one month and one year following the date he ceases to be a Non-Employee Director by reason of his or her “separation from service” (within the meaning of Treas. Reg.
§ 1.409A-1(h) or any successor provision) with the Company, subject to the limitations described in Section 8; 

(iii) effective for Annual Fees earned for services performed for any Plan Year beginning after 2013, the date elected by the
Participant, provided that the earliest permissible Fee Payment Date is the first trading day of the third calendar year beginning after the date on which Annual Fees would have been paid but for the deferral of such Annual Fees under the Plan and
the latest permissible Fee Payment Date is the first trading day of the tenth calendar year beginning after the calendar year in which Annual Fees would have been paid but for the deferral of such Annual Fees under the Plan; or 

(iv) effective for Annual Fees earned for services performed for any Plan Year beginning after 2013, the earlier of (A) the date
specified in Section 5(a)(4)(iii) or (B) one of the dates referenced in Section 5(a)(4)(i) or (ii). 
 A
Participant who is in active service as a Non-Employee Director may also file a subsequent election to delay the previously-scheduled Fee Payment Date (and to change the form of such payment from lump sum to installments or from installments to a
lump sum) with respect to Annual Fees deferred under this Section 5(a)(4) to a later Fee Payment Date that is not earlier than the fifth anniversary of the previously-scheduled Fee Payment Date or later than the 10th anniversary of the previously-scheduled Fee Payment Date, provided
that such a subsequent deferral election shall only be honored and shall not be recognized unless the Committee receives such subsequent election more than one year before the scheduled or re-scheduled Fee Payment Date. 

In the event the Annual Fees of a Participant are increased during any Plan Year, his or her elections in effect shall apply to the amount of such
increase. 
 (b) Notwithstanding the Participant’s elections made in accordance with Section 5(a), prior to the
December 15 preceding a Plan Year, the Board of Directors may, in its sole discretion: 
 (i) determine the portion
of each Non-Employee Director’s Annual Fees which must be paid in Stock for the next following Plan Year; and 

  
 5 








 (ii) mandate that any or all Annual Fees paid in cash or Stock be deferred in
accordance with the Participant’s elections under Sections 5(a)(3) and (4); 
 provided, however, that the Board of
Directors’ determination for any Plan Year shall remain in effect for subsequent Plan Years unless changed by the Board of Directors prior to the December 15 preceding the Plan Year with respect to which such change is effective. If the
Board of Directors makes such a determination, the Participant’s election under Section 5(a)(1) and Section 5(a)(2) above with respect to all Plan Years shall be calculated only with respect to any excess amount of the Annual Fees
remaining after payment or deferral is made in accordance with the Board of Directors’ determination, and the Participant’s election under 
Sections 5(a)(3) and (4) above shall remain in effect and apply to the amount of
Annual Fees payable in cash and Stock after application of the previous sentence. In the event a Non-Employee Director has failed to make an election under Section 5(a)(3), he or she will automatically receive payment of his or her Stock
Deferral Account and Cash Deferral Account in the form of a single lump sum. In the event a Non-Employee Director has failed to make an election under Section 5(a)(4), he or she will automatically receive payment of his or her Stock Deferral
Account and Cash Deferral Account on the date he or she ceases to be a Non-Employee Director by reason of his or her “separation from service” (within the meaning of Treas. Reg. § 1.409A-1(h) or any successor provision) with the
Company. 
 SECTION 6. Stock Deferral Accounts.  
 (a) Crediting of Annual Fees. The percentage of each Participant’s Annual Fees which are to be received in the form of Stock and deferred with respect to a Plan Year in accordance with
Section 5 shall be credited to the Participant’s Stock Deferral Account on each Fee Payment Date during the Plan Year, and shall be converted into that number of Stock Equivalents (rounded up to the nearest whole share) equal to the amount
so credited divided by the Director Purchase Price. 
 (b) Crediting of Dividend Equivalents. In the event a dividend is
paid in respect of the Stock, an amount equal to such dividend multiplied by the number of Stock Equivalents credited to a Participant’s Stock Deferral Account as of the record date for such dividend shall be credited to the Participant’s
Cash Deferral Account, effective as of the date such dividend is actually paid on the Stock. 
 (c) Adjustments to Deferral
Accounts. The number of Stock Equivalents credited to each Participant’s Stock Deferral Account shall be appropriately and equitably adjusted to reflect the occurrence of any merger, consolidation, recapitalization, stock split, reverse
stock split, stock dividend or other non-cash distribution affecting the outstanding Stock. Such adjustments shall be made by the direction of the Committee. 
 (d) Effect of Payments. The number of Stock Equivalents credited to a Participant’s Stock Deferral Account shall be reduced by the number of shares of Stock actually paid to such Participant
or his or her Beneficiary under the Plan. 

  
 6 








 (e) Vesting. The interest of a Participant in any amounts payable with respect to a
Stock Deferral Account shall be at all times fully vested and non-forfeitable. 
 SECTION 7. Cash Deferral Accounts. 

 (a) Crediting of Annual Fees and Dividend Equivalents. The percentage of each Participant’s Annual Fees which are
to be received in the form of cash and deferred with respect to a Plan Year in accordance with Section 5 shall be credited to the Participant’s Cash Deferral Account on each Fee Payment Date during the Plan Year. Dividend Equivalents will
be credited to a Participant’s Cash Deferral Account in accordance with Section 6(b). 
 (b) Crediting of
Interest. Interest shall be credited on and posted to each Cash Deferral Account as of the last day of each calendar month beginning the first calendar month following the effective date of the first deferral and ending the last calendar month
immediately preceding the date on which such amounts are distributed to the Participant, at an annual rate as determined by the Committee. 
 (c) Effect of Payments. The amount of cash credited to a Participant’s Cash Deferral Account shall be reduced by the amount of cash paid to such Participant or his or her Beneficiary under the
Plan. 
 (d) Vesting. The interest of a Participant in any amounts payable with respect to a Cash Deferral Account shall
be at all times fully vested and non-forfeitable. 
 SECTION 8. Payments.  

(a) General. At each time payment of all or a portion of a Participant’s Stock Deferral Account and/or Cash Deferral Account
is due pursuant to an election made in accordance with Section 5 (or pursuant to the death of a Participant in accordance with Section 8(c)), the Company shall pay Stock and cash directly to such Participant or his or her Beneficiary in an
amount equal to the portion of his or her Stock Deferral Account and/or Cash Deferral Account which is so payable. Payable amounts expressed in the form of Stock Equivalents shall be paid in Stock, and payable amounts expressed in the form of cash
shall be paid in cash. The Company shall make such payment directly to the Participant from its general assets and authorized but unissued Stock. 
 (b) Timing and Form of Payment. The payment of a Participant’s Stock Deferral Account and Cash Deferral Account shall commence on the date, and in the form, selected by the Participant in the
election described in Section 5; provided, however, if, as a result of a failure of this Plan to meet the requirements of Section 409A of the Internal Revenue Code of 1986, as amended, and the Treasury Regulations promulgated
thereunder, any portion of a Participant’s Stock Deferral Account or Cash Deferral Account (or the value thereof) becomes taxable to such Participant prior to the time such Stock Deferral Account or Cash Deferral Account is actually distributed
to such Participant, the Committee shall accelerate the payment of a portion of such Stock Deferral Account or Cash Deferral Account to such Participant in an amount equal to the amount that is required to be included in the income of such
Participant as a result of such failure. This Section 8(b) is intended to comply with, and shall at all times be construed as complying with, Treas. Reg. 1.409A-3(j)(4)(vii). 

  
 7 








 (c) Payment Upon Death. If a Participant dies before payment of his or her Stock
Deferral Account and Cash Deferral Account is completed, the balance remaining in such accounts shall be paid to the Participant’s Beneficiary in one lump sum as soon as practicable following the Participant’s death. 

(d) Dividends. Stock Equivalents credited to a Participant’s Stock Deferral Account shall continue to be credited with
dividends as described in Section 6(b) notwithstanding that such Participant has ceased to be a Non-Employee Director. 

(e) Interest. Cash credited to a Participant’s Cash Deferral Account shall continue to be credited with interest as
described in Section 7(b) notwithstanding that such Participant has ceased to be a Non-Employee Director. 

(f) Financial Hardship. Notwithstanding anything herein to the contrary, a Participant may request and receive a hardship
distribution, provided the Participant is able to demonstrate, to the satisfaction of the Committee, that he has suffered a Financial Hardship. A hardship distribution request must be made on the form provided by the Committee and is subject to the
discretion of the Committee. The amount distributed cannot exceed the lesser of (a) the aggregate of the Participant’s Cash Deferral Account and Stock Deferral Account, or (b) the amount necessary to satisfy the Participant’s
Financial Hardship. No distribution may be made prior to the time the Committee approves the distribution. This Section 8(f) is intended to comply with, and shall at all times be construed as complying with, Treas. Reg. 1.409A-3(i)(3).

 SECTION 9. Designation of Beneficiaries. A Participant may designate one or more Beneficiaries to receive the amounts
payable from the Participant’s Stock Deferral Account and Cash Deferral Account under the Plan in the event of such Participant’s death. Such designations shall be made on forms provided by the Committee. A Participant may from time to
time change his or her designated Beneficiaries, without the consent of such Beneficiaries, by filing a new designation in writing with the Committee. The Company and Committee may rely conclusively upon the Beneficiary designation last filed in
accordance with the terms of the Plan. 
 SECTION 10. Amendments to the Plan; Termination of the Plan. The Board of
Directors or the Committee may amend, alter, suspend, discontinue or terminate the Plan without the consent of any Participant; provided, however, that no such amendment, alteration, suspension, discontinuation, or termination of the
Plan shall materially and adversely affect the rights of such Participant with respect to payment of amounts previously credited to such Participant’s Stock Deferral Account and Cash Deferral Account. The Plan has no fixed termination date.
However, if the Plan is terminated in a manner consistent with the requirements of Treas. Reg. § 1.409A-3(j)(4)(ix), the Committee may, in its sole discretion, accelerate the payment of Participants’ Stock Deferral Accounts or
Cash Deferral Accounts in the form of a single lump sum regardless of any elections made by such Participants pursuant to Section 5(a).

 SECTION 11. General Provisions.  

(a) Limits on Transfer of Rights; Beneficiaries. No right or interest of a Participant under the Plan shall be subject in any
manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment by creditors of the Participant or his or her Beneficiary, or shall be transferable by a Participant otherwise than by will or the laws of
descent and distribution; provided, however, that a Participant may designate a Beneficiary in accordance with Section 9 to receive any payment under the Plan in the event of death of the Participant. A Beneficiary, guardian,
legal representative or other person claiming any rights under the Plan from or through any Participant shall be subject to all terms and conditions of the Plan applicable to such Participant. 

(b) Status of the Plan. The Plan is intended to be “unfunded” for Federal income tax purposes. The Plan shall not
cover any employee of the Company and is not intended to be subject to ERISA. With respect to any payment not yet made to a Participant under the Plan, nothing contained in the Plan shall give a Participant any rights that are greater than those of
a general creditor of the Company. 
 (c) No Rights of a Shareholder. No Participant shall have any of the rights or
privileges of a shareholder of the Company as a result of the making of an election under Section 5 of the Plan, or as a result of the establishing of or crediting of any amounts to a Stock Deferral Account under the Plan, until Stock is
actually distributed to the Participant pursuant to Section 8 of the Plan. 
 (d) No Right to Continued Election as
a Director. Nothing contained in the Plan shall confer, and no establishment of or crediting of any amounts to a Stock Deferral Account or Cash Deferral Account shall be construed as conferring, upon any Participant, any right to continue as a
member of the Board of Directors, or to interfere in any way with the right of the Company to increase or decrease the amount of the Annual Fees, or any other compensation payable to Non-Employee Directors. 

(e) Plan Expenses. All expenses and costs incurred in connection with the operation of the Plan shall be borne by the
Company. 
 (f) Governing Law. The validity, construction and effect of the Plan and any rules and regulations
relating to the Plan shall be determined in accordance with the laws of North Carolina, without giving effect to principles of conflicts of laws. 
 (g) Interpretation. Whenever necessary or appropriate in the Plan, where the context admits, the singular term and the related pronouns shall include the plural and the masculine gender shall
include the feminine gender.
