 WHEREAS, the Executive and Duke Energy entered into an
employment agreement, dated as of June 27, 2012 that became effective on July 2, 2012 (the “Employment Agreement”); and 
 WHEREAS, Duke Energy and the Executive have agreed that it is in the best interest of Duke Energy and the Executive for the Executive to resign, and they wish to set forth their mutual agreement as to the
terms and conditions of such resignation; 
 NOW, THEREFORE, Duke Energy and the Executive hereby agree as follows: 

1.    Resignation. Effective as of 12:01 a.m. on July 3, 2012 (the “Resignation Date”), the
Executive hereby resigns from his employment with Duke Energy, from his position as a member of the Board of Directors of Duke Energy, and from all other positions the Executive then holds with respect to Duke Energy and its subsidiaries or
affiliates (Duke Energy and all of its subsidiaries and affiliates, including Progress Energy, Inc. and any other predecessor entities, are hereinafter referred to as the “Affiliated Entities”), including as an officer or member of the
board of directors of any Affiliated Entity. Within 15 business days following the Resignation Date or such earlier time as required by applicable law, the Executive will be paid all of his salary and unused vacation earned or accrued through the
Resignation Date. 
 2.    Separation Payments and Benefits.  

a.    Subject to the Executive’s compliance with the terms of this Agreement and the
non-revocation of the release set forth in Paragraph 5 of this Agreement, following the Revocation Date (as defined in Paragraph 15 of this Agreement), Duke Energy shall pay or provide to the Executive the payments and benefits contemplated by
Section 12(b)(i) of the Employment Agreement to which the Executive would have been entitled upon a resignation by the Executive for “good reason” (as set forth on Exhibit A hereto). 

b.    Consistent with Section 5.08 of the Agreement and Plan of Merger, by and among Duke
Energy, Diamond Acquisition Corporation and Progress Energy, Inc., dated as of January 8, 2011, following the Resignation Date, Duke Energy shall provide or cause to be provided to the Executive coverage under Duke Energy’s directors’
and officers’ insurance policies for events that occurred while the Executive was a director or officer of any of the Affiliated Entities on the same terms and conditions applicable to other former senior executives and directors of Duke Energy
generally. 
 c.    Duke Energy shall reimburse the Executive for any reasonable and
necessary business expenses incurred by the Executive and unreimbursed on or prior to the Resignation Date pursuant to Duke Energy’s reimbursement policies, within 30 days following the Executive’s presentation of an invoice to Duke
Energy. 

 d.    Duke Energy shall reimburse the Executive for all
reasonable expenses incurred by him prior to the Effective Date in connection with his relocation to Charlotte, which are currently expected to be $30,000. 
 e.    Except as provided in Paragraphs 2, 3 and 4 of this Agreement, as well as any benefits that are accrued and vested as of the Resignation Date under employee benefit plans of an
Affiliated Entity in which the Executive participates, the Executive shall be entitled to no other compensation and/or benefits of any kind from any of the Affiliated Entities. 

3.    Equity Awards. Subject to the Executive’s compliance with the terms of this Agreement and the
non-revocation of the Release set forth in Paragraph 5 of this Agreement, all currently outstanding equity awards under the applicable Progress Energy, Inc. equity plans held by the Executive as of the Resignation Date shall immediately vest on the
Resignation Date pursuant to Section 12(b)(i)(E) of the Employment Agreement. 
 4.    Additional
Payments/280G. Within ten days following the date that is six months after the Resignation Date, and in consideration for the Executive’s agreement to cooperate with Duke Energy and not to disparage the Duke Energy Parties (as defined
below), the Executive shall be paid an amount (the “Additional Payment”) that is equal to the lesser of (a) $1,500,000 and (b) the portion of the payment described in clause (a) of this Paragraph 4 (taking into account the
value of reasonable compensation for services to be rendered by the Executive before or after the Resignation Date, including any non-competition provisions that apply to the Executive and Duke Energy) that the Executive may be paid that does not,
when aggregated with all other payments, benefits or distributions in the nature of compensation to or for the Executive’s benefit, whether paid, payable or provided pursuant to this Agreement or otherwise that are contingent upon a change in
ownership or control within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Payments”), exceed an amount equal to three times the Executive’s “base amount” within the meaning of
Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) minus $5,000. In the event that the Executive is not eligible to be paid any portion of the Additional Payment by reason of the application of the limitation
described in clause (b) of the preceding sentence, notwithstanding anything to the contrary in this Agreement or in Section 12(e) of the Employment Agreement and in consideration for the Executive’s agreement to cooperate with Duke
Energy and not to disparage the Duke Energy Parties (as defined below), the Executive shall, subject to the Executive’s cooperation with Duke Energy in making determinations with respect to Section 280G of the Code, taking into account the
value of reasonable compensation for services to be rendered by the Executive before or after the Resignation Date, including any non-competition provisions that apply to the Executive and Duke Energy, be eligible to receive “Gross-Up
Payments” consistent with the terms of Section 11 of the Progress Energy, Inc. Management Change-in-Control Plan and an additional payment of $500,000 within ten days following the date that is six months after the Resignation Date, which
payment, for the avoidance of doubt shall be covered by the “Gross-Up Payments”. 

5.    Release of Claims. 

a.    In consideration of and in exchange for the benefits provided to him under this Agreement,
including but not necessarily limited to Duke Energy’s acceptance of the Executive’s resignation effective as of the Resignation Date, and the benefits set forth in Paragraphs 2, 3 and 4 of this Agreement, the Executive, of his own free
will, voluntarily and unconditionally releases and forever discharges (the “Release”) the Affiliated Entities, their respective directors, officers, employees, agents, stockholders, successors and assigns (both individually and in their
official capacities with Duke Energy) (the “Duke Releasees”) from, any and all past or present causes of action, suits, agreements or other claims which the 

  
 -2-

 
Executive, his dependents, relatives, heirs, executors, administrators, successors and assigns has or may hereafter have from the beginning of time to the date hereof against Duke Energy or the
Duke Releasees upon or by reason of any matter, cause or thing whatsoever, including, but not limited to, any matters arising out of his employment by the Affiliated Entities, and the cessation of said employment or any claim for compensation, and

of 1974, the Older Workers Benefit Protection Act of 1990, the Americans with Disabilities Act of 1990, the North Carolina Equal Employment Protection Act and any other federal, state or local law, regulation or ordinance, or public policy, contract
or tort law having any bearing whatsoever on the terms and conditions of employment or termination of employment. The Release shall not, however, constitute a waiver of any of the Executive’s rights to compensation and benefits due under this
Agreement. 
 b.    The Executive acknowledges that he has received a copy of this Agreement
prior to its execution and has been advised hereby of his opportunity to review and consider the Release for 21 days prior to its execution. The Executive further acknowledges that he has been advised hereby to consult with an attorney prior to
executing this Agreement. The Executive enters into this Agreement having freely and knowingly elected, after due consideration, to execute this Agreement and to fulfill the promises set forth herein. The Release shall be revocable by the Executive
during the seven-day period following its execution, and shall not become effective or enforceable until the expiration of such seven-day period. In the event of such a revocation, the Executive shall not be entitled to the consideration under this
Agreement set forth in Paragraphs 2, 3 and 4 above. 
 c.    The Executive represents and
warrants that there has been no assignment or other transfer of any interest in any claim which the Executive may have against Duke Energy or any of the Duke Releasees. The Executive represents that he has not commenced or joined in any claim,
charge, action or proceeding whatsoever against Duke Energy or any of the Duke Releasees arising out of or relating to any of the matters set forth in this Release. The Executive further agrees that he will not seek or be entitled to any personal
recovery in any claim, charge, action or proceeding whatsoever against Duke Energy or any of the Duke Releasees for any of the matters set forth in the Release. 

d.    The Executive acknowledges that, in his decision to enter into this Agreement, including the
Release, he has not relied on any representations, promises or agreements of any kind, including oral statements by representatives of Duke Energy or any of the Duke Releasees, except as set forth in the Release and this Agreement. 

e.    Nothing contained in the Release will be deemed or construed as an admission of wrongdoing or
liability on the part of Duke Energy or any of the Duke Releasees. 
 f.    Nothing in this
Agreement shall be construed to prohibit, restrict or otherwise discourage the Executive from participating in protected activity as defined in 10 CFR 50.7 and Section 211 of the Energy Reorganization Act of 1974, including, but not limited to
reporting any suspected instance of illegal activity of any nature, any nuclear safety concern, any workplace safety concern, any public safety concern, or any other matter within the United States Nuclear Regulatory Commission’s
(“NRC”) regulatory responsibilities to the NRC, the United States Department of Labor, or any other federal or state governmental agency. This Agreement further does not prohibit the Executive from participating in any way in any
state or federal administrative, judicial, or legislative proceeding or investigation with respect to any 

  
 -3-

 
claims and matters not resolved and terminated pursuant to this Agreement. With respect to any claims and matters resolved and terminated pursuant to this Agreement, the Executive is free to
participate in any federal or state administrative, judicial, or legislative proceeding or investigation if subpoenaed. The Executive shall give Duke Energy, through its legal counsel, notice, including a copy of the subpoena, within 24 hours
of receipt thereof. 
 6.    Non-disparagement. The Executive shall not disparage any of the
Affiliated Entities, their directors, officers, employees, agents, stockholders, successors and assigns (both individually and in their official capacities with Duke Energy) (the “Duke Energy Parties”) or any Duke Energy Parties’
goods, services, employees, customers, business relationships, reputation or financial condition. Duke Energy shall instruct its current officers and directors (as such terms are used for purposes of Section 16 of the Securities Exchange Act of
1934) not to disparage the Executive and shall treat any such disparagement as a violation of Duke Energy’s Code of Business Ethics. For purposes of this Agreement, to “disparage” means to make statements, whether oral or written,
whether direct or indirect, whether true or false and whether acting alone or through any other person, that cast the subject of the statement in a critical or unfavorable light or that otherwise cause damage to, or intend to embarrass, the subject
of the statement. Attached to this Agreement as Exhibit B is a press release regarding Executive’s termination of employment. Neither the Executive nor Duke Energy shall make any public statement regarding Executive’s termination of
employment that is materially inconsistent with such press release. Nothing in the foregoing will preclude either the Executive or Duke Energy from providing truthful disclosures as required by applicable law or legal process. 

7.    Confidential Information; Return of Property; Restrictive Covenants. The Executive shall be subject to
each of the covenants set forth in Section 11 of the Employment Agreement, including Section 11(a) (Confidentiality), Section 11(b) (Noncompetition/Nonsolicitation), Section 11(c) (Forfeiture and Repayments, which shall also be
applicable in the event of a violation of Section 6 of this Agreement), Section 11(d) (Scope of Restrictions) and Section 11(e) (Consideration; Survival). 
 8.    Cooperation. The Executive agrees to cooperate with Duke Energy in connection with his departure as reasonably requested by Duke Energy, including with respect to any
communications to current and former employees or directors of any of the Affiliated Entities as may reasonably be requested by Duke Energy in connection with such departure. The Executive will be available, upon reasonable notice, to respond to
questions and provide assistance to Duke Energy regarding matters for which he was responsible and about which he had knowledge in connection with his employment with any of the Affiliated Entities. The Executive also will cooperate in any potential
or pending litigation or arbitration that may involve him in any capacity as a result of his employment with, or service as a member of the board of directors of, any of the Affiliated Entities. This includes, if necessary, meeting at mutually
convenient times with attorneys of any of the Affiliated Entities, attending meetings, depositions and trial, and providing truthful testimony. 
 9.    Governing Law and Forum Selection. The Parties agree that any dispute, claim or controversy based on common law, equity, or any federal, state, or local statute,
ordinance, or regulation (other than workers’ compensation claims) arising out of or relating in any way to the Executive’s employment shall be addressed, in all respects, consistent with Section 18 of the Employment Agreement.

 10.    Applicable Law. Except to the extent that federal law governs, this Agreement will be
governed by and construed and enforced in accordance with the laws of the State of North Carolina, without regard to any applicable state’s choice of law provisions. 

  
 -4-

 11.    Integrated Agreement; Amendments. Except with respect to
the provisions of the Employment Agreement expressly referenced herein, this Agreement sets forth the entire agreement of Duke Energy and the Executive with respect to the subject matter hereof, and supersedes all other agreements between any of the
Affiliated Entities and the Executive and any employment or severance plan, policy, agreement or arrangement of any of the Affiliated Entities. Without limiting the generality of the foregoing, the Executive expressly acknowledges and agrees that
except as specifically set forth in this Agreement, he is not entitled to receive any severance pay, severance benefits, compensation or employee benefits of any kind whatsoever from Duke Energy or any of its affiliates. This Agreement may not be
amended unless the amendments are in writing and signed by the Executive and an authorized representative of Duke Energy. 

12.    Severability. The invalidity or unenforceability of any particular provision in this Agreement shall
not affect the other provisions hereof, and this Agreement shall be construed in all respects as if the invalid or unenforceable provision were omitted. 
 13.    Taxes. Notwithstanding any other provision of this Agreement, Duke Energy may withhold from any amounts payable under this Agreement, or any other benefits
received pursuant hereto, such Federal, state and/or local taxes as shall be required to be withheld under any applicable law or regulation. The obligations under this Agreement are intended to comply with the requirements of Section 409A of
the Code, or an exemption or exclusion therefrom, provided that the Executive acknowledges and agrees that he shall be solely responsible for any taxes and/or penalties imposed under Section 409A of the Code. Each payment under this Agreement
shall be treated as a separate payment for purposes of Section 409A of the Code. In no event may the Executive, directly or indirectly, designate the calendar year of any payment to be made under this Agreement. If the Executive is a
“specified employee” (within the meaning of Section 409A of the Code) then any payments that are required to be made to the Executive pursuant to this Agreement that constitute the deferral of compensation (within the meaning of
Treasury Regulations Section 1.409A-1(b) and that would in the absence of this Paragraph 13 have been paid to the Executive within six months and one day of the Resignation Date shall not be paid to the Executive during such period, but shall
instead be accumulated and paid to the Executive in a lump sum on the earlier of (i) the day after the date that is six months from the Resignation Date and (ii) if the Executive shall die prior to the expiration of such six-month period,
as soon as practicable following the date of the Executive’s death. All reimbursements and in-kind benefits that constitute deferred compensation within the meaning of Section 409A of the Code provided under this Agreement shall be made or
provided in accordance with the requirements of Section 409A of the Code, including, without limitation, that (i) in no event shall reimbursements by Duke Energy under this Agreement be made later than the end of the calendar year next
following the calendar year in which the applicable fees and expenses were incurred; (ii) the amount of in-kind benefits that Duke Energy is obligated to pay or provide in any given calendar year shall not affect the in-kind benefits that Duke
Energy is obligated to pay or provide in any other calendar year; and (iii) the Executive’s right to have Duke Energy pay or provide such reimbursements and in-kind benefits may not be liquidated or exchanged for any other benefit.

 14.    Successors. This Agreement is personal to the Executive and without the prior written
consent of Duke Energy shall not be assignable by the Executive other than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s legal representatives and the legal
representatives of his estate to the extent applicable. This Agreement shall inure to the benefit of and be binding upon Duke Energy and its successors and assigns. 
 15.    Representations and Warranties. By signing this Agreement, the Executive warrants that he:

 PRESS RELEASE 

  
 B-1Amended and Restated Duke Energy Corporation Executive Cash Balance Plan

 Exhibit 10.3 
 DUKE ENERGY CORPORATION 
 EXECUTIVE CASH BALANCE PLAN 

As Amended and Restated Effective July 2, 2012 
 ARTICLE I 
 PURPOSE OF PLAN 

The purpose of the Duke Energy Corporation Executive Cash Balance Plan (the “Plan”) is to provide additional retirement
benefits for a select group of management or highly compensated employees. The Plan originally was effective as of January 1, 1997 and was amended thereafter from time to time. Effective January 1, 1999, the Plan replaced the PanEnergy
Corp Key Executive Retirement Benefit Equalization Plan and all benefits provided thereunder were provided in accordance with the terms set forth herein. The Plan is intended to be a non-qualified, unfunded plan of deferred compensation for a select
group of management or highly compensated employees under the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and shall be so interpreted and administered. Effective August 26, 2008, the Plan was amended and
restated in its entirety in order to comply with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”). Effective on July 2, 2012, the Plan is hereby amended and restated in its entirety, as set forth herein,
to reflect the participation by, and assumption of the obligations of, certain individuals who (i) as of January 8, 2011 served on the Progress Energy, Inc. Senior Management Committee, (ii) participated in or, but for the service
eligibility requirements, would have participated in the Amended and Restated Supplemental Senior Executive Retirement Plan of Progress Energy, Inc. (the “Progress Nonqualified Plan”), and (iii) were employees of Progress Energy,
Inc., or its affiliates, in each case immediately prior to the Progress Merger Effective Time (as defined in Exhibit A). 
 The
Plan was divided into two separate parts, one of which is referred to herein as “Part I” and the other is referred to herein as “Part II.” Any “amounts deferred” under the Plan in taxable years beginning before
January 1, 2005 (within the meaning of Section 409A of the Code) and any earnings thereon shall be governed by the terms of Part I of the Plan, as set forth herein. It is intended that such amounts and the earnings thereon shall be exempt
from the application of Section 409A of the Code. Nothing contained herein is intended to materially enhance a benefit or right existing under Part I of the Plan as of October 3, 2004, or add a new material benefit or right to Part I of
the Plan. As of January 1, 2005 (“Effective Date”), Part I of the Plan was frozen, and neither the Company, its affiliates nor any individual shall make or permit to be made any additional contributions or deferrals under Part I of
the Plan (other than earnings) on or after that date. 
 Any “amounts deferred” in taxable years beginning on or after
January 1, 2005 (within the meaning of Section 409A of the Code) and any earnings thereon shall be governed by the terms and conditions of Part II of the Plan, as set forth herein. To the extent that any of those amounts were credited
under the Plan prior to the Effective Date (the “Transferred Amounts”), then the Committee shall transfer the Transferred Amounts from Part I of the Plan to Part II of the Plan and credit those amounts to the appropriate bookkeeping
accounts under Part II of this Plan, as selected by the Committee in its sole discretion. As a result of such transfer and crediting, all of the Company’s obligations and Participant’s rights with respect to the Transferred Amounts under
Part I of the Plan, if any, shall automatically be extinguished and become obligations and rights under Part II of this Plan without further action. For purposes of clarity, the obligations assumed from the Progress Nonqualified Plan shall be
governed by the terms and conditions of Part II of the Plan, as set forth herein.

 2.20 “Specified Employee” shall mean, as of any date, a “specified employee”, as defined in Section 409A of the Code (as determined under the Company’s policy for identifying
specified employees on the relevant date), of the Company or any entity which would be considered to be a single employer with the Company under Section 414(b) or Section 414(c) of the Code. 

2.21 “Supplemental Credit” means a credit that is added to a Participant’s Supplemental Account pursuant to
Section 4.3. 
 2.22 “Supplemental Benefit” means the benefit provided under Section 4.3 of the Plan.

 2.23 “Supplemental Retirement Plan” means the Supplemental Retirement Plan for Employees of Duke Power Company as
it existed on December 31, 1996. 
 2.24 “Supplemental Security Plan” means the Duke Power Company Supplemental
Security Plan as it existed on December 31, 1996. 
 ARTICLE III 

ELIGIBILITY 
 3.1 General Rule. Any Employee designated by the Committee shall be eligible to participate in the Plan and shall remain eligible as long as he continues to be an Employee or, except for a Progress
Nonqualified Plan Participant, until designated ineligible by the Committee. Notwithstanding the foregoing, an Employee who is not a member of a “select group of management or highly compensated employees” within the meaning of ERISA, may

  
 4 

 
not participate in the Plan. Participants shall not receive any benefits under the terms of the Supplemental Retirement Plan, the Supplemental Security Plan or the Equalization Plan. For purposes
of clarity, the eligibility rules of Article III are subject to amendment as provided in Article VIII. 
 3.2 Former
Employees. Former Employees, (i) whose Company employment terminated before January 1, 1997, and who had accrued benefits under the Supplemental Retirement Plan or Supplemental Security Plan, or (ii) whose Company employment
terminated before January 1, 1999, and who had accrued benefits under the Equalization Plan, will receive payment, or will continue to receive payment, of such benefits under the terms of such plans. Such former Employees will not participate
in this Plan. 
 3.3 Progress Nonqualified Plan Participants. Effective as of the Progress Merger Effective Time, each
individual who (i) as of January 8, 2011 served on the Progress Energy, Inc. Senior Management Committee, (ii) participated in or, but for the service eligibility requirements, would have participated in the Progress Nonqualified
Plan, and (iii) was an employee of Progress Energy, Inc., or its affiliates, in each case immediately prior to the Progress Merger Effective Time (each, a “Progress Nonqualified Plan Participant”) shall be eligible to participate in
the Plan as of the Progress Merger Effective Time and shall remain eligible as long as he continues to be an Employee. A Progress Nonqualified Plan Participant who incurs a Separation from Service shall not be eligible to participate again in the
Plan upon reemployment with the Company unless and until designated by the Committee as eligible to participate in the Plan following such reemployment. The obligations and rights of the Progress Nonqualified Plan Participants under the Progress
Nonqualified Plan shall automatically be extinguished as of the Progress Merger Effective Time and shall become obligations and rights under this Plan, as set forth herein. For purposes of clarity, the obligations and rights of participants in the
Progress Nonqualified Plan other than the Progress Nonqualified Plan Participants shall not become obligations or rights under this Plan. 
 ARTICLE IV 
 BENEFITS 

4.1 General Rule. The Plan provides a Make-Whole Benefit and may provide a Supplemental Benefit. Each Participant shall have a
Make-Whole Account (with an opening balance of zero dollars ($0.00)), which is a bookkeeping account established under this Plan and shall be eligible for a Make-Whole Benefit. The Committee will determine whether a Participant is to be eligible for
a Supplemental Benefit, in which case a “Supplemental Account,” which is a bookkeeping account, shall be established. 

4.2 Pay Credits to the Make-Whole Account. Under the Make-Whole Benefit, for any month that a Participant is eligible to
participate in this Plan, the Participant’s Make-Whole Account shall receive a Pay Credit equal to the excess, if any, of (a) the pay credit that would have been provided under the Retirement Cash Balance Plan for the month if the
Retirement Cash Balance Plan used the definition of Compensation set forth herein and, to the extent determined by the Committee from time to time, other types of excluded pay were treated as eligible compensation under such Plan; over (b) the
pay credit for the month that is actually made to the Participant’s account under the Retirement Cash Balance Plan. A Participant, while “Disabled” as defined in the Retirement Cash Balance Plan and continuing to receive pay credits
to the Participant’s account under the Retirement Cash Balance Plan, shall continue to receive 

  
 5 

 
Pay Credits to the Participant’s Make-Whole Account determined on the same basis as his continued pay credits under the Retirement Cash Balance Plan, and based upon his eligible
Compensation. In addition, the Make-Whole Benefit provides a Pay Credit to the Participant’s Make-Whole Account equal to any reduction in a benefit under the Retirement Cash Balance Plan (for purposes of clarity, note that this includes the
Progress Energy Pension Plan) resulting from the limitations imposed by Section 415 of the Code. Where an opening account balance under the Retirement Cash Balance Plan has been established for a Participant, the Committee, in its sole
discretion, may establish an opening balance for the Participant’s Make-Whole Account that is designed to provide a transition benefit comparable to the benefit provided through the Retirement Cash Balance Plan opening account balance, but
without regard to the limitations imposed by Sections 401(a)(17) or 415 of the Code. If the value of the benefit which a vested Participant had accrued under the Supplemental Retirement Plan as of December 31, 1996, is greater than the value of
the Participant’s Make-Whole Account on the date the Participant retires, such higher value shall apply. 
 4.3
Supplemental Credits. A Participant’s Supplemental Account shall receive such Supplemental Credits, in such amounts and at such times, as the Committee, in its sole discretion, may determine. Supplemental Credits may include, but are not
limited to, an opening account balance or a one-time credit in recognition of the December 31, 1998, discontinuance of supplemental pay credits. Notwithstanding Sections 4.3 and 4.4 to the contrary, the Minimum Benefit feature of
Section 4.3(e) of the Plan, as in effect prior to January 1, 1999, is preserved herein and incorporated by reference. 

4.4 Interest Credits. An Interest Credit will be added to a Participant’s Make-Whole Account and to a Participant’s
Supplemental Account as of the end of each calendar month ending prior to the month in which the respective account is fully distributed or forfeited. The amount of the Interest Credit for a month will equal the balance of the respective account as
of the end of the prior month (after adding any Pay Credit, Supplemental Credit and Interest Credit for the prior month and subtracting any payment or forfeiture for the prior month) multiplied by the Interest Factor for the month. Notwithstanding
the foregoing, and for purposes of Part I only, Interest Credits to the Supplemental Account of a Participant whose employment with the Company terminates before attaining the earliest retirement age under the Retirement Cash Balance Plan will be
suspended beginning with the month during which employment terminates and will not resume until the month following the month during which payment of the Supplemental Benefit commences. 

ARTICLE V 

VESTING 

5.1 General Rule. Unless the Committee provides otherwise for a particular Participant at the time the Participant initially
becomes eligible to participate in the Plan or at the time of an award of a particular Supplemental Credit (and any Interest Credits thereto), a Participant will become fully vested in the Participant’s Make-Whole Account and the
Participant’s Supplemental Account, if any, when (i) the Participant becomes vested under the Retirement Cash Balance Plan, or (ii) the Participant’s employment with the Company terminates on account of the Participant’s
death or the Participant having become “Disabled”, as defined in the Retirement Cash Balance Plan. If a Participant’s employment with the Company terminates and the Participant is not fully vested, the unvested portion of the
Participant’s Make-Whole Account and of the Participant’s Supplemental Account, if any, shall be immediately 

  
 6 

 
forfeited and no benefit under the Plan shall be paid with respect thereto. Notwithstanding the foregoing, a Progress Nonqualified Plan Participant shall become vested in, and entitled to a
benefit under, the Plan after completing: (a) 10 years of Service (as defined in Exhibit A) and (b) three years of employment at the level of “Senior Vice President and above,” which shall include (I) for periods prior to
the Progress Merger Effective Time, employment with Progress Energy, Inc. and its affiliates at the Senior Vice President and above level, and (II) for periods after the Progress Merger Effective Time, any employment with the Company. 

5.2 Prior Supplemental Credits. Notwithstanding the foregoing, any one-time Supplemental Credit to a Participant’s
Supplemental Account that is made in recognition of the December 31, 1998 discontinuance of supplemental pay credit, and any Interest Credits thereon, shall not vest, and shall be forfeited if the Participant’s employment with the Company
terminates before January 1, 2004, unless such employment termination is on account of the Participant’s retirement under the Retirement Cash Balance Plan, death, or the Participant having become “Disabled,” as defined in the
Retirement Cash Balance Plan, or unless such employment termination is by the Company other than for “cause”. The Company shall have “cause” to terminate the Participant’s employment upon (a) the willful and continued
failure by the Participant to substantially perform his employment duties (other than any such failure resulting from the Participant’s incapacity due to physical or mental illness) after demand for substantial performance is delivered by the
Company, specifically identifying the manner in which the Company believes the Participant has not substantially performed his duties, or (b) the willful engaging by the Participant in misconduct which is materially injurious to the Company,
monetarily or otherwise. For purposes of this Section, no act, or failure to act, on the Participant’s part shall be considered “willful” unless done, or omitted to be done, by him not in good faith and without reasonable belief that
his action or omission was in the best interest of the Company. 
 5.3 Change in Control. In the event of a Change in
Control, all Participant accounts under the Plan shall become fully and immediately vested and non-forfeitable and shall thereafter be maintained and paid in accordance with the terms of this Plan. 

ARTICLE VI 

PAYMENT OF BENEFITS 
 6.1(a) Timing of Payments Under Part I. For purposes of Part I of the Plan, a Participant whose Company employment terminates prior to the Participant’s earliest retirement age under the
Retirement Cash Balance Plan will receive, or will begin to receive, payment of his vested Make-Whole Account and his vested Supplemental Account, if any, as soon as administratively feasible following the month in which the Participant attains age
55. A Participant whose Company employment terminates after the Participant’s earliest retirement age under the Retirement Cash Balance Plan will receive, or will begin to receive, payment of his vested Make-Whole Account and his vested
Supplemental Account, if any, as soon as administratively feasible following the month in which the Participant’s employment terminates. However, a Participant, while “Disabled” (as defined in the Retirement Cash Balance Plan) and
continuing to receive pay credits to the Participant’s account under the Retirement Cash Balance Plan, shall not receive payment of benefits during the period the Participant receives such pay credits. Any other Participant whose Company
employment terminates and whose Make-Whole Account and Supplemental Account, if any, have a combined balance, as of the last day of the month during which employment terminated, of less than $25,000, will receive payment of his

  
 7 

 
vested Make-Whole Account and his vested Supplemental Account, if any, in a single sum, as soon as administratively feasible following the month in which the Participant’s employment with
the Company terminates. 
 6.1(b) Timing of Payments Under Part II. Except as otherwise provided in Section 6.9, for
purposes of Part II of the Plan, and subject to Section 6.5, a Participant whose Company employment terminates on or after December 31, 2006 will receive, or will begin to receive, payment of his vested Make-Whole Account and his vested
Supplemental Account, if any, within 60 days after Separation from Service. 
 6.2(a)(1) Election of Form of Benefit Under
Part I. With respect to Part I of the Plan, each Participant has been provided the opportunity to elect from among the forms of benefit payment specified in Section 6.2(b)(1) the manner in which such Participant’s vested Make-Whole
Account and his vested Supplemental Account, if any, shall be paid. A Participant may change his form of benefit payment election under Part I of the Plan at any time, and from time to time, by completing such form as the Committee provides and
filing the completed form with the Committee. No such change shall become effective unless and until the Participant has continued in employment with the Company for at least one year from the date on which the Committee receives notification of the
change. 
 6.2(a)(2) Election of Form of Benefit Under Part II. With respect to Part II of the Plan, no later than
December 31, 2008 (or such earlier date set by the Committee), each Participant must elect from among the forms of benefit payment specified in Section 6.2(b)(2) the manner in which such Participant’s vested Make-Whole Account and his
vested Supplemental Account, if any, shall be paid. The election described in this Section 6.2(a)(2) shall be subject to such terms and conditions as the Committee may specify in its sole discretion and shall be consistent with the terms of
Notice 2007-86 and the applicable proposed and final Treasury Regulations issued under Section 409A of the Code. To the extent that a Participant does not designate the manner in which such Participant’s vested Make-Whole Account and his
vested Supplemental Account, if any, shall be paid as provided in this Section 6.2(a)(2) (or such designation does not comply with the terms of Part II of the Plan), such accounts shall be paid in a single lump sum. Notwithstanding anything
contained in the Plan to the contrary, except Section 6.2(d) or Section 6.9, or any other plan, policy, practice or program, contract or agreement with the Company or the Affiliated Group (unless otherwise specifically provided therein in
a specific reference to this Plan), a Participant who becomes eligible to participate in the Plan after December 31, 2008 shall have no right to choose a form of payment for his accounts, and, instead, his vested Make-Whole Account and his
vested Supplemental Account, if any, shall be paid in a single lump sum. 
 6.2(b)(1) Forms of Benefit Under Part I. The
forms of benefit payment available under Part I of the Plan are: 
  

	 	(A)	single lump sum payment; 

  

	 	(B)	monthly payments for three years; 

  

	 	(C)	monthly payments for ten years; and 

  

	 	(D)	monthly payments for fifteen years. 

  
 8 

 At such time as benefits under the Plan become payable with respect to a Participant, such benefits shall be
paid in accordance with the benefit payment form then in effect unless otherwise expressly provided by the Plan. 
 6.2(b)(2)
Forms of Benefit Under Part II. Except as otherwise provided in Section 6.9, the forms of benefit payment available under Part II of the Plan are: 
  

	 	(A)	single lump sum payment; 

  

	 	(B)	monthly payments for two to ten years; and 

  

	 	(C)	monthly payments for fifteen years. 

 At such
time as benefits under the Plan become payable with respect to a Participant, such benefits shall be paid in accordance with the benefit payment form then in effect unless otherwise expressly provided by the Plan. 

6.2(c) Calculation of Installment Payments. In the event of monthly installment payments, the amount of the payment for a
particular month shall be calculated as follows: 
  

					
	Monthly amount =	  	 V
	  	 
	  	N	  	 

 where 

N represents the number of months remaining in the payment term and 

V represents the sum of the balance of the Participant’s Make-Whole Account and the balance of the Participant’s Supplemental
Account, if any, determined as of the end of the prior month after adding any Pay Credits, Supplemental Credits and Interest Credits for the prior month and subtracting any payment or forfeiture for the prior month. 

6.2(d) Forms of Benefit – Supplemental Account. Notwithstanding any other provision of the Plan, prior to making a
Supplemental Credit, the Committee may provide that the portion of the Participant’s vested Supplemental Account that is attributable to such Supplemental Credit shall be distributed in any benefit payment form specified in advance by the
Committee. 
 6.3 Payments in Cash. Any benefit payment due under the Plan shall be paid in cash. 

6.4 Financial Hardship. Upon written request by a Participant, the Committee may distribute to a Participant who is receiving a
monthly payment form of distribution, such amount of the remaining balance of the Participant’s vested Make-Whole Account and vested Supplemental Account, if any, which the Committee determines is necessary to provide for a financial hardship
suffered by the Participant. For purposes of Part I of the Plan, the term “financial hardship” shall mean a severe financial hardship as determined under federal income tax law, regulations and rulings which are applicable to non-qualified
deferred compensation plans. For purposes of Part II of the Plan, the term “financial hardship” shall mean an “unforeseeable emergency” as defined under Section 409A of the Code. Payment shall be made within 60 days
following the determination that a withdrawal shall be permitted under this Section, or such later date as may be required under Section 6.5. 

  
 9 

 6.5 Mandatory Six-Month Delay Under Part II. Except as otherwise provided in Sections
6.6(a), 6.6(b) and 6.9, and to the extent required under Section 409A of the Code, with respect to any Participant who is a Specified Employee as of his or her Separation from Service, the payment of benefits from Part II of the Plan that are
otherwise payable pursuant to the Participant’s Separation from Service shall commence within 60 days after the first business day of the seventh month following such Separation from Service (or if earlier, upon the Participant’s death).

 6.6 Discretionary Acceleration of Payment. To the extent permitted by Section 409A of the Code, the Committee
may, in its sole discretion, accelerate the time or schedule of a payment of benefits under Part II of the Plan as provided in this Section. The provisions of this Section are intended to comply with the exception to accelerated payments under
Treasury Regulation Section 1.409A-3(j) and shall be interpreted and administered accordingly. Except as otherwise specifically provided in Part II of this Plan, the Committee may not accelerate the time or schedule of any payment or amount
scheduled to be paid under the Plan within the meaning of Section 409A of the Code. 
 (a) Domestic Relations Order.
The Committee may, in its sole discretion, accelerate the time or schedule of a payment under Part II of the Plan to an individual other than the Participant as may be necessary to fulfill a domestic relations order (as defined in
Section 414(p)(1)(B) of the Code). 
 (b) Employment Taxes. The Committee may, in its sole discretion, provide for
the acceleration of the time or schedule of a payment under Part II of the Plan to pay the Federal Insurance Contributions Act (FICA) tax imposed under Sections 3101, 3121(a), and 3121(v)(2) of the Code, or the Railroad Retirement Act (RRTA) tax
imposed under Sections 3201, 3211, 3231(e)(1), and 3231(e)(8) of the Code, where applicable, on compensation deferred under the Plan (the FICA or RRTA amount). Additionally, the Committee may, in its sole discretion, provide for the acceleration of
the time or schedule of a payment, to pay the income tax at source on wages imposed under Section 3401 of the Code or the corresponding withholding provisions of applicable state, local, or foreign tax laws as a result of the payment of the
FICA or RRTA amount, and to pay the additional income tax at source on wages attributable to the pyramiding Section 3401 of the Code wages and taxes. However, the total payment under this acceleration provision must not exceed the aggregate of
the FICA or RRTA amount, and the income tax withholding related to such FICA or RRTA amount. 
 (c) Payment Upon Income
Inclusion Under Section 409A. Subject to Section 6.5 hereof, the Committee may, in its sole discretion, provide for the acceleration of the time or schedule of a payment under Part II of the Plan at any time the Plan fails to meet the
requirements of Section 409A of the Code. The payment may not exceed the amount required to be included in income as a result of the failure to comply with the requirements of Section 409A of the Code. 

(d) Payment of State, Local, or Foreign Taxes. Subject to Section 6.5 hereof, the Committee may, in its sole discretion,
provide for the acceleration of the time or schedule of a payment under Part II of the Plan to reflect payment of state, local, or foreign tax obligations arising from participation in the Plan that apply to an amount deferred under Part II of the
Plan before the amount is paid or made available to the Participant (the state, local, or foreign tax amount). Such payment may not exceed the amount of such taxes due as a result of participation

  
 10 

 
in the Plan. The payment may be made in the form of withholding pursuant to provisions of applicable state, local, or foreign law or by payment directly to the participant. Additionally, the
Committee may, in its sole discretion, provide for the acceleration of the time or schedule of a payment under Part II of the Plan to pay the income tax at source on wages imposed under Section 3401 of the Code as a result of such payment and
to pay the additional income tax at source on wages imposed under Section 3401 of the Code attributable to such additional wages and taxes. However, the total payment under this acceleration provision must not exceed the aggregate of the state,
local, and foreign tax amount, and the income tax withholding related to such state, local, and foreign tax amount. 
 (e)
Certain Offsets. Subject to Section 6.5 hereof, the Committee may, in its sole discretion, provide for the acceleration of the time or schedule of a payment under Part II of the Plan as satisfaction of a debt of the Participant to the
Company (or any entity which would be considered to be a single employer with the Company under Section 414(b) or Section 414(c) of the Code), where such debt is incurred in the ordinary course of the service relationship between the
Company (or any entity which would be considered to be a single employer with the Company under Section 414(b) or Section 414(c) of the Code) and the Participant, the entire amount of reduction in any of the taxable years of the Company
(or any entity which would be considered to be a single employer with the Company under Section 414(b) or Section 414(c) of the Code) does not exceed $5,000, and the reduction is made at the same time and in the same amount as the debt
otherwise would have been due and collected from the Participant. 
 (f) Bona Fide Disputes as to a Right to a Payment.
Subject to Section 6.5 hereof, the Committee may, in its sole discretion, provide for the acceleration of the time or schedule of a payment under Part II of the Plan where such payments occur as part of a settlement between the Participant and
the Company (or any entity which would be considered to be a single employer with the Company under Section 414(b) or Section 414(c) of the Code) of an arm’s length, bona fide dispute as to the Participant’s right to the deferred
amount. 
 (g) Other Events and Conditions. Subject to Section 6.5 hereof, a payment may be accelerated upon such
other events and conditions as the Internal Revenue Service may prescribe in generally applicable guidance published in the Internal Revenue Bulletin. 
 (h) Small Payments. Subject to Section 6.5, the Committee may, in its sole discretion, require a mandatory lump sum payment of the portion of a Participant’s benefit payable under Part II
of the Plan if such amount does not exceed the applicable dollar amount under Section 402(g)(1)(B) of the Code, provided that the payment results in the termination and liquidation of the entirety of the Participant’s benefit payable under
Part II of the Plan plus amounts under all agreements, methods, programs or other arrangements with respect to which deferrals of compensation are treated as having been deferred under a single nonqualified deferred compensation plan under
Section 409A of the Code. 
 6.7 Delay of Payments. To the extent permitted under Section 409A of the Code, the
Committee may, in its sole discretion, delay payment of benefits under Part II of the Plan under any of the following circumstances, provided that the Committee treats all payments to similarly situated Participants on a reasonably consistent basis:

 (a) Payments Subject to Section 162(m). A payment may be delayed to the extent that the Committee reasonably
anticipates that if the payment were made as scheduled, the 

  
 11 

 
Company’s deduction with respect to such payment would not be permitted due to the application of Section 162(m) of the Code. If a payment is delayed pursuant to this Section, then the
payment must be made either (i) during the Company’s first taxable year in which the Committee reasonably anticipates, or should reasonably anticipate, that if the payment is made during such year, the deduction of such payment will not be
barred by application of Section 162(m) of the Code, or (ii) during the period beginning with the first business day of the seventh month following the Participant’s Separation from Service (the “six month anniversary”) and
ending on the later of (x) the last day of the taxable year of the Company in which the six month anniversary occurs or (y) the 15th day of the third month following the six month anniversary. Where any scheduled payment to a specific
Participant in a Company’s taxable year is delayed in accordance with this paragraph, all scheduled payments to that Participant that could be delayed in accordance with this paragraph must also be delayed. The Committee may not provide the
Participant an election with respect to the timing of the payment under this Section. For purposes of this Section, the term Company includes any entity which would be considered to be a single employer with the Company under Section 414(b) or
Section 414(c) of the Code. 
 (b) Federal Securities Laws or Other Applicable Laws. A payment may be delayed where
the Committee reasonably anticipates that the making of the payment will violate federal securities laws or other applicable law; provided that the delayed payment is made at the earliest date at which the Committee reasonably anticipates that the
making of the payment will not cause such violation. For purposes of the preceding sentence, the making of a payment that would cause inclusion in gross income or the application of any penalty provision or other provision of the Code is not treated
as a violation of applicable law. 
 (c) Other Events and Conditions. A payment may be delayed upon such other events and
conditions as the Internal Revenue Service may prescribe in generally applicable guidance published in the Internal Revenue Bulletin. 
 6.8 Actual Date of Payment. If calculation of the amount of the payment under Part II of the Plan is not administratively practicable due to events beyond the control of the Participant (or
Beneficiary), the payment will be treated as made upon the date specified under Part II of the Plan if the payment is made during the first calendar year in which the calculation of the amount of the payment is administratively practicable.
Notwithstanding the foregoing, payment must be made no later than the latest possible date permitted under Section 409A of the Code. Moreover, notwithstanding any other provision of this Plan to the contrary except Section 6.5, and to the
extent permitted by Section 409A of the Code, a payment will be treated as made upon the date specified under Part II of the Plan if the payment is made as close as administratively practicable to the relevant payment date specified herein, and
in any event within the same calendar year. 
 6.9 Progress Nonqualified Plan Participants. Notwithstanding anything
contained in this Plan to the contrary, the amount of benefit and payment terms for a Progress Nonqualified Plan Participant shall be determined in accordance with the provisions of this Section 6.9. For purposes of clarity, (i) this
Section 6.9 reflects the obligations and rights assumed from the Progress Nonqualified Plan with respect to the Progress Nonqualified Plan Participants and (ii) the Progress Nonqualified Plan Participants shall have no further rights under
the Progress Nonqualified Plan. 

  
 12 

 (a) Calculation of Progress Nonqualified Plan Participant Benefit. A Progress
Nonqualified Plan Participant’s benefit from the Plan shall equal the greater of (i) or (ii), where (i) and (ii) are as follows: 
  

	 	(i)	The amount in this Section 6.9(a)(i) is the sum of the Frozen Progress Nonqualified Plan Benefit (as defined in Exhibit A) and ECBP Benefit for Progress
Nonqualified Plan Participant (as defined in Exhibit A). 

  

	 	(ii)	The amount in this Section 6.9(a)(ii) is the Minimum Progress Nonqualified Plan Benefit (as defined in Exhibit A). 

(b) General Payment Terms. Except as otherwise provided in Sections 6.9(c), (d) or (e), the Progress Nonqualified Plan
Participant’s benefit shall be paid in the form of (i) if the Progress Nonqualified Plan Participant does not have an Eligible Spouse on the date payments under this Plan commence, a Single Life Annuity, commencing within 60 days after the
first day of the calendar month next following the Progress Nonqualified Plan Participant’s Separation from Service, and ending with a payment for the month in which the Progress Nonqualified Plan Participant’s death occurs; provided that
the monthly installments shall be guaranteed for 120 monthly payments with any such guaranteed payments remaining at such Progress Nonqualified Plan Participant’s death payable to his Beneficiary or, (ii) if the Progress Nonqualified Plan
Participant has an Eligible Spouse on the date payments under this Plan commence, then a 50% Qualified Joint and Survivor Annuity for the life of the Progress Nonqualified Plan Participant, and after the Progress Nonqualified Plan Participant’s
death, for the life of the surviving Eligible Spouse, if any. 
 (c) Deferred Vested Benefits. If a Progress Nonqualified
Plan Participant incurs a Separation from Service after completing 10 or more years of Service and before being eligible for a normal or early retirement benefit under Paragraph 1 or 2 of Exhibit A, then except as provided in Section 6.9(e),
the Progress Nonqualified Plan Participant’s benefit under Section 6.9(a) shall be paid in monthly installments, commencing on the first day of the calendar month coinciding with or next following the Progress Nonqualified Plan
Participant’s 65th birthday and ending with a payment for the month in which the Progress Nonqualified Plan Participant’s death occurs; provided that, if the Progress Nonqualified Plan Participant is receiving, or dies after attaining age
55 while entitled to receive, the deferred vested benefit, then the Progress Nonqualified Plan Participant’s Eligible Spouse (if any) shall be entitled to an amount equal to 50% of the deferred vested benefit the deceased Progress Nonqualified
Plan Participant was receiving immediately prior to his death (or would have been entitled to receive if the Progress Nonqualified Plan Participant had survived until his 65th birthday), which amount shall be payable to the Eligible Spouse in
monthly installments commencing in the month following the Progress Nonqualified Plan Participant’s death and ending with a payment for the month in which the Eligible Spouse’s death occurs. 

(d) Pre-Retirement Death Benefits. If a Progress Nonqualified Plan Participant dies while in the employ of the Company after
completing 10 or more years of Service, the Progress Nonqualified Plan Participant’s Eligible Spouse shall be eligible for an annuity in an amount equal to the standard benefit or, if greater, alternative benefit (as specified below)
commencing, except as provided in Section 6.9(e), in the month following the Progress Nonqualified Plan Participant’s death and shall continue thereafter ending with a payment for the month in which the Eligible Spouse’s death occurs.
The standard benefit shall be an amount equal to the greater of (i) or (ii), where 

  
 13 

	 	(i)	is the sum of (A) and (B), where (A) is the excess, if any, of (I) forty percent (40%) of the Target Pre-Retirement Death Benefit (as defined in
Exhibit A) over (II) the Spouse’s Pension (as defined in Exhibit A), each determined as if the Progress Nonqualified Plan Participant died as of the Progress Merger Effective Time, and (B) the benefit under Section 7.1 with the
Eligible Spouse as Beneficiary (i.e., the sum of the balance in the Progress Nonqualified Plan Participant’s Make-Whole Benefit Account and Supplemental Benefit Account) determined as of the Progress Nonqualified Plan Participant’s
actual date of death, actuarially adjusted using the actuarial assumptions specified in the definition of ECBP Benefit for Progress Nonqualified Plan Participant in Paragraph 4 of Exhibit A to an annuity payable for the life of the Eligible Spouse,
and 

  

	 	(ii)	is the excess, if any between (I) forty percent (40%) of the Target Pre-Retirement Death Benefit (as defined in Exhibit A) over (II) the Spouse’s Pension
(as defined in Exhibit A), each determined as of the Progress Nonqualified Plan Participant’s actual date of death. 

 The
alternative benefit shall be available to a surviving Eligible Spouse of the Progress Nonqualified Plan Participant who dies while in the employ of the Company after attaining age 55 with 15 years of Service and shall be equal to 50% of the benefit
the Progress Nonqualified Plan Participant would have been entitled to receive under Section 6.9(a) calculated as if the Progress Nonqualified Plan Participant had a Separation from Service immediately prior to his death. 

(e) Mandatory Six-Month Delay. Except as otherwise provided in Sections 6.6(a) and (b), and to the extent required under
Section 409A of the Code, with respect to any Progress Nonqualified Plan Participant who is a Specified Employee as of his Separation from Service, all amounts that would otherwise be paid under this Plan during the first six months following
the Separation for Service shall instead be accumulated through and paid (without interest) on the first business day of the seventh month following the Separation from Service. If the Progress Nonqualified Plan Participant dies following Separation
from Service but prior to the commencement of payments under this paragraph (e), then, (i) in the case of benefits payable pursuant to Section 6.9(b), the Progress Nonqualified Plan Participant’s surviving Eligible Spouse, if any, or
Beneficiary, as applicable, shall be entitled to receive the same death benefit as if the Progress Nonqualified Plan Participant had commenced receiving benefit payments as of the first day of the month prior to his death, and (ii) in the case
of benefits payable pursuant to Section 6.9(c), the Progress Nonqualified Plan Participant’s surviving Eligible Spouse, if any, or Beneficiary, as applicable, shall be eligible for the surviving spouse benefit set forth therein.

 (f) Definitions. See Article II and Exhibit A. 

ARTICLE VII 

DEATH BENEFITS 
 7.1 Designation of Beneficiary. Except as otherwise provided in Section 6.9, upon a Participant’s death, any remaining balance of a Participant’s vested Make-Whole Account and

  
 14 

 
vested Supplemental Account shall be paid to the Participant’s Beneficiary as a death benefit. The Committee will provide each Participant with a form to be completed and filed with the
Committee whereby the Participant may designate a Beneficiary. 
 7.2 Failure to Designate a Beneficiary. If the
Participant does not designate a Beneficiary, or if the Beneficiary who is designated should predecease the Participant, the death benefit for a deceased Participant shall be paid to the estate of the Participant, as the Participant’s
Beneficiary. 
 7.3 Death Prior to Commencement of Payment. Except as otherwise provided in Section 6.9, if a
Participant should die while still employed by the Company or otherwise before payment of any Plan benefits has commenced, payments of any death benefit shall be made to the Participant’s Beneficiary in the same benefit payment form elected by
the Participant, or otherwise required, under Section 6.2. Notwithstanding the foregoing, with respect to Part I of the Plan only: (i) if the Beneficiary is the estate, then the death benefit shall be paid in a single lump sum, and
(ii) if the death benefit is less than $25,000, the death benefit shall be paid to the Participant’s Beneficiary in a single lump sum. 
 7.4 Death After Commencement of Payment. Except as otherwise provided in Section 6.9, if a Participant should die after payment of Plan benefits has commenced, payment of any death benefit
will be made to the Participant’s Beneficiary as a continuation of the benefit payment form that had been in effect for the Participant. Notwithstanding the foregoing, with respect to Part I of the Plan only, if the Beneficiary is the estate,
then the death benefit shall be paid in a single lump sum. 
 7.5 Death Benefit for Certain Participants. If an Employee
who was an active participant in the Supplemental Security Plan on December 31, 1996, should die while still employed by the Company, the portion of the death benefit attributable to the Employee’s Supplemental Account, determined after
taking into account other death benefits attributable to the elimination of the Supplemental Security Plan, shall not be less than the amount determined by multiplying two point five (2.5) times the annualized base rate of pay of the Employee
on the date of death. 
 ARTICLE VIII 
 AMENDMENT AND TERMINATION 
 The Committee retains the sole and unilateral
right to terminate, amend, modify or supplement this Plan, in whole or in part, at anytime. The Committee may delegate the right to amend the Plan, subject to any limitations it may impose, to an officer of the Company. No such action shall
adversely affect a Participant’s right to receive amounts then credited to a Participant’s account with respect to events occurring prior to the date of such amendment. Moreover, no such action shall in any way affect a Participant’s
accrued benefit or the right to payment thereof under the provisions of Section 6.9 as in effect immediately prior to the amendment. With respect to Part II of the Plan, subject to Section 6.5 hereof, the Committee may, in its sole
discretion to the extent permitted in Section 409A of the Code, provide for the acceleration of the time or schedule of a payment under the Plan upon the termination of the Plan. In the event of a Change in Control, the Plan shall become
irrevocable and may not be amended or terminated without the written consent of each Plan Participant who may be affected in any way by such amendment or termination either at the time of such action or at any time

  
 15 

 
thereafter. This restriction in the event of a Change in Control shall be determined by reference to the date any amendment or resolution terminating the Plan is actually signed by an authorized
party rather than the date such action purports to be effective. 
 ARTICLE IX 

ADMINISTRATION 
 9.1 Top Hat Plan. The Company intends for the Plan to be an unfunded “top-hat” plan for a select group of management or highly compensated employees which is exempt from substantially all
of the requirements of Title I of ERISA pursuant to Sections 201(2), 301(a)(3), and 401(a)(1) of ERISA. The Company is the Plan sponsor under Section 3(16)(B) of ERISA. 
 9.2 Plan Administrator. The Committee shall have the authority to control and manage the operation and administration of the Plan except as otherwise expressly provided in this Plan document. The
Committee may designate other persons to carry out fiduciary responsibilities under the Plan. The Committee is the administrator of the Plan within the meaning Section 3(16)(A) of ERISA. As administrator, the Committee has the authority
(without limitation as to other authority) to delegate its duties to agents and to make rules and regulations that it believes are necessary or appropriate to carry out the Plan. The Committee has the discretion (i) to interpret and construe
the terms and provisions of the Plan (including any rules or regulations adopted under the Plan), (ii) to determine questions of eligibility to participate in the Plan and (iii) to make factual determinations in connection with any of the
foregoing. A decision of the Committee with respect to any matter pertaining to the Plan including without limitation the Employees determined to be Participants, the benefits payable, and the construction or interpretation of any provision thereof,
shall be conclusive and binding upon all interested persons. Benefits under the Plan shall be paid only if the Committee decides in its discretion that the applicant is entitled to benefits under the Plan. 

ARTICLE X 

CLAIMS PROCEDURE 
 10.1 Claim. A person with an interest in the Plan shall have the right to file a claim for benefits under the Plan and to appeal any denial of a claim for benefits. Any request or application for a
Plan benefit or to clarify the claimant’s rights to future benefits under the terms of the Plan shall be considered to be a claim. 
 10.2 Written Claim. A claim for benefits will be considered as having been made when submitted in writing by the claimant (or by such claimant’s authorized representative) to the Committee. No
particular form is required for the claim, but the written claim must identify the name of the claimant and describe generally the benefit to which the claimant believes he is entitled. The claim may be delivered personally during normal business
hours or mailed to the Committee. 
 10.3 Committee Determination. The Committee will determine whether, or to what
extent, the claim may be allowed or denied under the terms of the Plan. If the claim is wholly or partially denied, the claimant shall be so informed by written notice within 90 days after the day the claim is submitted unless special circumstances
require an extension of time for processing the claim. If such an extension of time for processing is required, written notice of the extension 

  
 16 

 
shall be furnished to the claimant prior to the termination of the initial 90-day period. Such extension may not exceed an additional 90 days from the end of the initial 90-day period. The
extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Plan expects to render the final decision. If notice of denial of a claim (in whole or in part) is not furnished within the initial
90-day period after the claim is submitted (or, if applicable, the extended 90-day period), the claimant shall consider that his claim has been denied just as if he had received actual notice of denial. 

10.4 Notice of Determination. The notice informing the claimant that his claim has been wholly or partially denied shall be
written in a manner calculated to be understood by the claimant and shall include: 
  

	 	(1)	The specific reason(s) for the denial. 

  

	 	(2)	Specific reference to pertinent Plan provisions on which the denial is based. 

 

	 	(3)	A description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is
necessary. 

  

	 	(4)	Appropriate information as to the steps to be taken if the claimant wishes to submit his claim for review. 

10.5 Appeal. If the claim is wholly or partially denied, the claimant (or his authorized representative) may file an appeal of the
denied claim with the Committee requesting that the claim be reviewed. The Committee shall conduct a full and fair review of each appealed claim and its denial. Unless the Committee notifies the claimant that due to the nature of the benefit and
other attendant circumstances he is entitled to a greater period of time within which to submit his request for review of a denied claim, the claimant shall have 60 days after he (or his authorized representative) receives written notice of denial
of his claim within which such request must be submitted to the Committee. 
 10.6 Request for Review. The request for
review of a denied claim must be made in writing. In connection with making such request, the claimant or his authorized representative may: 
  

	 	(1)	Review pertinent documents. 

  

	 	(2)	Submit issues and comments in writing. 

 10.7 Determination of Appeal. The decision of the Committee regarding the appeal shall be promptly given to the claimant in writing and shall normally be given no later than 60 days following the
receipt of the request for review. However, if special circumstances (for example, if the Committee decides to hold a hearing on the appeal) require a further extension of time for processing, the decision shall be rendered as soon as possible, but
no later than 120 days after receipt of the request for review. However, if the Committee holds regularly scheduled meetings at least quarterly, a decision on review shall be made by no later than the date of the meeting which immediately follows
the Plan’s receipt of a request for review, unless the request is filed within 30 days preceding the date of such meeting. In such case, a decision may be made by no later than the date of the second meeting following the Plan’s receipt of
the request for review. If special circumstances (for example, if the Committee decides to hold a hearing on the appeal) require a further extension of time for processing, the decision shall be rendered as soon

  
 17 

 
as possible, but no later than the third meeting following the Plan’s receipt of the request for review. If special circumstances require that the decision will be made beyond the initial
time for furnishing the decision, written notice of the extension shall be furnished to the claimant (or his authorized representative) prior to the commencement of the extension. The decision on review shall be in writing and shall be furnished to
the claimant or to his authorized representative within the appropriate time for the decision. 
 10.8 Hearing. The
Committee may, in its sole discretion, decide to hold a hearing if it determines that a hearing is necessary or appropriate in order to make a full and fair review of the appealed claim. 

10.9 Decision. The decision on review shall include specific reasons for the decision, written in a manner calculated to be
understood by the claimant, as well as specific references to the pertinent Plan provisions on which the decision is based. 

10.10 Exhaustion of Appeals. A person must exhaust his rights to file a claim and to request a review of the denial of his claim
before bringing any civil action to recover benefits due to him under the terms of the Plan, to enforce his rights under the terms of the Plan, or to clarify his rights to future benefits under the terms of the Plan. 

10.11 Committee’s Authority. The Committee shall exercise its responsibility and authority under this claims procedure as a
fiduciary and, in such capacity, shall have the discretionary authority and responsibility (1) to interpret and construe the Plan and any rules or regulations under the Plan, (2) to determine the eligibility of Employees to participate in
the Plan, and the rights of Participants to receive benefits under the Plan, and (3) to make factual determinations in connection with any of the foregoing. Benefits under the Plan shall be paid only if the Committee decides in its discretion
that the applicant is entitled to benefits under the Plan. 
 10.12 Civil Action. Any civil action brought with respect
to a decision of the Committee on review shall be brought within one year of the mailing of the written decision to the claimant. 
 ARTICLE XI 
 NATURE OF COMPANY’S OBLIGATION 

11.1 Nature of Obligation. The Company’s obligation to the Participant under this Plan shall be an unfunded and unsecured
promise to pay. The rights of a Participant or Beneficiary under this Plan shall be solely those of an unsecured general creditor of the Company. The Company shall not be obligated under any circumstances to set aside or hold assets to fund its
financial obligations under this Plan. 
 11.2 Financing. Notwithstanding the foregoing, the Company may, in its sole
discretion establish such accounts, trusts, insurance policies or arrangements, or any other mechanisms it deems necessary or appropriate to account for or fund its obligations under the Plan. Any assets which the Company may set aside, acquire or
hold to help cover its financial liabilities under this Plan are and remain general assets of the Company subject to the claims of its creditors. The Company does not give, and the Plan does not give, any beneficial ownership interest in any assets
of the Company to a Participant or Beneficiary. All rights of ownership in 

  
 18 

 
any assets are and remain in the Company. Any general asset used or acquired by the Company in connection with the liabilities it has assumed under this Plan shall not be deemed to be held under
any trust for the benefit of the Participant or any Beneficiary, and no general asset shall be considered security for the performance of the obligations of the Company. Any asset shall remain a general, unpledged, and unrestricted asset of the
Company. The Company’s liability for payment of benefits shall be determined only under the provisions of this Plan, as it may be amended from time to time. 
 ARTICLE XII 
 GENERAL PROVISIONS 

12.1 No Right to Employment. Nothing in this Plan shall be deemed to give any person the right to remain in the employ of the
Company or affect the right of the Company to terminate any Participant’s employment with or without cause. 
 12.2 No
Assignment. No right or benefit under the Plan shall be subject to anticipation, alienation, sale, assignment, pledge, encumbrance or charge. Any attempt to anticipate, alienate, sell, assign, pledge, encumber or charge these benefits shall be
void. No right or benefit under this Plan shall in any manner be liable for or subject to the debts, contracts, liabilities, or torts of the person entitled to the benefit. If any Participant or Beneficiary under the Plan should become bankrupt or
attempt to anticipate, alienate, sell, assign, pledge, encumber or charge any right to a benefit hereunder, then the right or benefit, in the discretion of the Committee, shall cease. In these circumstances, the Committee may hold or apply the
benefit payment or payments, or any part of it, for the benefit of the Participant or his Beneficiary, the Participant’s spouse, children, or other dependents, or any of them, in any manner and in any portion that the Committee may deem proper.
Notwithstanding the foregoing, to the extent permitted by Section 409A of the Code and subject to Section 6.6, the Committee shall honor a judgment, order or decree from a state domestic relations court which requires the payment of part
or all of a Participant’s or Beneficiary’s interest under this Plan to an “alternate payee” as defined in Section 414(p) of the Code. 
 12.3 Withholding. Any amount required to be withheld under applicable Federal, state and local tax laws (including any amounts required to be withheld under Section 3121(v) of the Code) will
be withheld in such manner as the Committee will determine and any payment under the Plan will be reduced by the amount so withheld, as well as by any other lawful withholding. 

12.4 Governing Law. This Plan shall be construed and administered in accordance with the laws of the State of North Carolina to
the extent that such laws are not preempted by Federal law. 
 12.5 Transfer of Accounts. The Make-Whole Account and
Supplemental Account, if any, of each Spectra Energy Participant maintained under the Plan immediately prior to the Distribution Date shall be transferred to the Spectra Energy Corp Executive Cash Balance Plan and assumed by Spectra Energy Corp as
of the Distribution Date. Each such Spectra Energy Participant shall have no further rights under the Plan immediately after his Make-Whole Account and Supplemental Account, if any, are transferred to the Spectra Energy Corp Executive Cash Balance
Plan and assumed by Spectra Energy Corp in accordance with the terms and conditions of the Employee Matters Agreement by and between Duke Energy Corporation and Spectra Energy Corp (the “Employee Matters Agreement”). Capitalized terms used
in this Section 12.5 that are not defined in this Plan shall have the meaning set forth in the Employee Matters Agreement. 

  
 19 

 12.6 Compliance with Section 409A of the Code. It is intended that Part II of
the Plan comply with the provisions of Section 409A of the Code, so as to prevent the inclusion in gross income of any amounts deferred hereunder in a taxable year that is prior to the taxable year or years in which such amounts would otherwise
actually be paid or made available to Participants or Beneficiaries. This Plan shall be construed, administered, and governed in a manner that effects such intent, and the Company shall not take any action that would be inconsistent with such
intent. Although the Company shall use its best efforts to avoid the imposition of taxation, interest and penalties under Section 409A of the Code, the tax treatment of deferrals under this Plan is not warranted or guaranteed. Neither the
Company, the other members of the Affiliated Group, their respective directors, officers, employees and advisors, the Board, nor any committee shall be held liable for any taxes, interest, penalties or other monetary amounts owed by any Participant,
Beneficiary or other taxpayer as a result of the Plan. Any reference in this Plan to Section 409A of the Code will also include any proposed, temporary or final regulations, or any other guidance, promulgated with respect to such
Section 409A of the Code by the U.S. Department of Treasury or the Internal Revenue Service. For purposes of the Plan, the phrase “permitted by Section 409A of the Code,” or words or phrases of similar import, shall mean that the
event or circumstance shall only be permitted to the extent it would not cause an amount deferred or payable under the Plan to be includible in the gross income of a Participant or Beneficiary under Section 409A(a)(1) of the Code. 

12.7 Electronic or Other Media. Notwithstanding any other provision of the Plan to the contrary, including any provision that
requires the use of a written instrument, the Committee may establish procedures for the use of electronic or other media in communications and transactions between the Plan or the Committee and Participants and Beneficiaries. Electronic or other
media may include, but are not limited to, e-mail, the Internet, intranet systems and automated telephonic response systems. 

IN WITNESS WHEREOF, this amendment and restatement of the Plan is executed on behalf of Duke Energy Corporation this 2nd day of July,
2012.

 EXHIBIT A 
 PROGRESS NONQUALIFIED PLAN PARTICIPANT’S BENEFITS UNDER SECTION 6.9 
 This Exhibit A
is used to determine the benefits provided under Section 6.9 to Progress Nonqualified Plan Participants (or their Eligible Spouses or Beneficiaries). 
 1. Normal Retirement Benefit. A Progress Nonqualified Plan Participant who incurs a Separation from Service on or after his Progress Normal Retirement Date shall be eligible for the normal
retirement benefit, which is a monthly amount equal to his Target Normal Retirement Benefit reduced by the sum of (a) his Assumed Normal Retirement Pension Benefit and (b) his Social Security Benefit. 

2. Early Retirement Benefit. A Progress Nonqualified Plan Participant who incurs a Separation from Service upon or after his
attainment of age 55 with at least 15 years of Service (except for purposes of calculating benefits payable under Paragraph 3 and 4 of this Exhibit A below, as applicable) but prior to his Progress Normal Retirement Date, shall be eligible for the
early retirement benefit, which is a monthly amount equal to his Target Early Retirement Benefit reduced by the sum of (a) his Assumed Early Retirement Pension Benefit and (b) his Social Security Benefit; provided, however, such benefit
will be reduced, where applicable, by the following: (i) the amount of 2.5% for each year that such benefit is received prior to his Progress Normal Retirement Date, and (ii) if such eligible Progress Nonqualified Plan Participant’s
projected years of Service at his Progress Normal Retirement Date are less than 15, his Target Early Retirement Benefit and his Assumed Early Retirement Pension Benefit shall be calculated based upon his actual years of Service at his Progress Early
Retirement Date rather than upon his projected years of Service at his Progress Normal Retirement Date. 
 3. Deferred Vested
Benefit. A Progress Nonqualified Plan Participant who incurs a Separation from Service after completing 10 or more years of Service but who is not eligible for a retirement benefit under Paragraph 1 or 2 of this Exhibit A shall be eligible for
one of the following benefits: (a) if at Separation from Service the Progress Nonqualified Plan Participant is not entitled to a deferred vested Progress Qualified Retirement Pension under the Progress Qualified Retirement Plan or an early
retirement Progress Qualified Retirement Pension under the Progress Qualified Retirement Plan, his deferred vested benefit shall be a monthly amount equal to his Target Deferred Vested Benefit reduced by his Social Security Benefit; (b) if at
Separation from Service such eligible Progress Nonqualified Plan Participant is entitled to a deferred vested Progress Qualified Retirement Pension under the Progress Qualified Retirement Plan, his deferred vested benefit shall be a monthly amount
equal to his Target Deferred Vested Benefit reduced by the sum of (i) his Assumed Deferred Vested Pension Benefit and (ii) his Social Security Benefit; (c) if at his Separation from Service such eligible Progress Nonqualified Plan
Participant is entitled to an early retirement Progress Qualified Retirement Pension pursuant to Section 5.02 of the Progress Qualified Retirement Plan, his deferred vested benefit shall be a monthly amount equal to his Target Deferred Vested
Benefit reduced by the sum of (a) his Assumed Early Retirement Pension Benefit and (b) his Social Security Benefit; provided, however, such Assumed Early Retirement Pension Benefit shall be calculated at his Separation from Service as
provided in this Exhibit A, but without regard to projected pay credits, and, if applicable, projected transition credits. 

  
 21 

 4. Definitions. For purposes of Section 6.9, this Exhibit A, and sections
expressly stated, the following terms shall have the following meanings unless a different meaning is clearly required by the context: 

Affiliated Group. Shall have, for purposes of determining whether a Progress Nonqualified Plan Participant has incurred a Separation from Service
with the Affiliated Group, the meaning provided in Section 2.1, except that the phrase “at least 45 percent” is deleted in each place that it appears and replaced with the phrase “at least 50 percent”. 

Assumed Deferred Vested Pension Benefit. Shall mean the monthly benefit of the deferred vested Progress Qualified Retirement Pension to commence
on his Progress Normal Retirement Date payable in the form of an annuity to which a separated Progress Nonqualified Plan Participant would be entitled under the Progress Qualified Retirement Plan, calculated with the following assumptions based on
such Progress Nonqualified Plan Participant’s marital status at the time benefits hereunder commence: (a) In the case of a Progress Nonqualified Plan Participant with an Eligible Spouse, in the form of a 50% Qualified Joint and Survivor
Annuity as provided in the Progress Qualified Retirement Plan. (b) In the case of a Progress Nonqualified Plan Participant without an Eligible Spouse, in the form of a Single Life Annuity as provided in the Progress Qualified Retirement Plan.
(c) Without regard to any other benefit payment option under the Progress Qualified Retirement Plan. 
 Assumed Early Retirement Pension
Benefit. Shall mean the monthly benefit of the normal retirement Progress Qualified Retirement Pension payable in the form of an annuity to which a Progress Nonqualified Plan Participant would be entitled under the Progress Qualified Retirement
Plan projected at his Progress Normal Retirement Date based on the following: 
  

	(I)	The Progress Nonqualified Plan Participant’s account balance under the Progress Qualified Retirement Plan is determined at the time of the Progress Nonqualified
Plan Participant’s actual Separation from Service. The foregoing is increased by (i) the pay credits and, if applicable, transition credits, that the Progress Nonqualified Plan Participant would have received from his actual Separation
from Service through his Progress Normal Retirement Date using the Progress Nonqualified Plan Participant’s rate of compensation at his actual Separation from Service (or, if compensation under the Progress Qualified Retirement Plan includes
variable compensation, then compensation for the calendar year prior to his actual Separation from Service) and the pay credit table in effect at his actual Separation from Service and (ii) interest credits in accordance with the rate schedule
(or, if applicable, variable rate) in effect on the Progress Nonqualified Plan Participant’s actual Separation from Service 

  

	(II)	The amount determined in (I) above is adjusted based upon the Progress Nonqualified Plan Participant’s marital status at the time benefits hereunder commence
as follows: (a) In the case of a Progress Nonqualified Plan Participant with an Eligible Spouse, in the form of a 50% Qualified Joint and Survivor Annuity as provided in the Progress Qualified Retirement Plan. (b) In the case of a Progress
Nonqualified Plan Participant without an Eligible Spouse, in the form of a Single Life Annuity as provided in the Progress Qualified Retirement Plan. (c) Without regard to any other benefit payment option under the Progress Qualified Retirement
Plan. 

  
 22 

 Assumed Normal Retirement Pension Benefit. Shall mean the monthly benefit of the normal retirement
Progress Qualified Retirement Pension payable in the form of an annuity to which a Progress Nonqualified Plan Participant would be entitled under the Progress Qualified Retirement Plan if he retired at his Progress Normal Retirement Date, calculated
with the following assumptions based on his marital status at the time benefits hereunder commence: (a) In the case of a Progress Nonqualified Plan Participant with an Eligible Spouse, in the form of a 50% Qualified Joint and Survivor Annuity
as provided in the Progress Qualified Retirement Plan. (b) In the case of a Progress Nonqualified Plan Participant without an Eligible Spouse, in the form of a Single Life Annuity as provided in the Progress Qualified Retirement Plan.
(c) Without regard to any other benefit payment option under the Progress Qualified Retirement Plan. 
 ECBP Benefit for Progress
Nonqualified Plan Participant. Shall mean the benefit under Article IV of the Plan (i.e., the sum of the balance in the Progress Nonqualified Plan Participant’s Make-Whole Benefit Account and Supplemental Benefit Account attributable
to pay and supplemental credits made from the Progress Merger Effective Time until Separation from Service) determined at the time payment actually occurs under Section 6.9(b), actuarially adjusted to the payment form in which the Progress
Nonqualified Plan Participant’s Frozen Progress Nonqualified Plan Benefit is payable at commencement (for purposes of clarity, single life annuity, single life annuity with 120 monthly payments guaranteed, or 50% Qualified Joint and Survivor
Annuity, as applicable). Any actuarial adjustment shall be determined using the mortality and interest assumptions under the Duke Energy Retirement Cash Balance Plan as in effect from time to time for converting the cash balance account to a form of
payment. For purposes of clarity, note that, as of the Progress Merger Effective Time, the Duke Energy Retirement Cash Balance Plan uses the applicable mortality table as defined in Section 417(e)(3) of the Code and the applicable interest rate
as provided in Section 417(e) of the Code for the month of August prior to the beginning of the year during which commencement is to occur to convert the cash balance to a single life annuity and uses the 1983 Group Annuity Mortality Table
weighted 50% male and 50% female and 7% interest compounded annually to convert the single life annuity to other optional forms of payment. 

Eligible Spouse. Shall mean the spouse of a Progress Nonqualified Plan Participant who, under the laws of the State where the marriage was
contracted, is deemed married to that Progress Nonqualified Plan Participant on the date on which the payments from this Plan are to begin to the Progress Nonqualified Plan Participant, except that, for purposes of Section 6.9(c) and (d),
Eligible Spouse shall mean a person who is married to a Progress Nonqualified Plan Participant for a period of at least one year prior to his death. For purposes of applying Sections 6.8, 11.1, 11.2, 12.2 and 12.6 of the Plan, an Eligible Spouse of
a Progress Nonqualified Plan Participant shall be deemed to be that Progress Nonqualified Plan Participant’s “Beneficiary”. 

50% Qualified Joint and Survivor Annuity. Shall have the meaning given to such term in the Progress Qualified Retirement Plan. 

Final Average Salary. Shall mean, a Progress Nonqualified Plan Participant’s average monthly Progress Salary (as defined below) during the 36
completed calendar months of highest compensation within the 120-month period immediately preceding the Progress Merger Effective Time. In determining average monthly Progress Salary (i) annual incentives and other similar payments shall be
deemed received in twelve (12) equal payments beginning with the eleventh preceding month and ending with the month such payments were actually made (for purposes of 

  
 23 

 
clarity, the payment must actually have been made prior to the Progress Merger Effective Time for such payment to be included in determining Final Average Salary), and (ii) amounts of
compensation deferred under any deferred compensation plan or arrangement shall be deemed received in the months such payments would have been received assuming no deferral had occurred. For years of Service granted under the terms of a written
employment agreement, Progress Salary during each such month is deemed to be zero dollars ($0.00) for purposes of calculating Final Average Salary. Solely for purposes of determining a Progress Nonqualified Plan Participant’s Minimum Progress
Nonqualified Plan Benefit under Section 6.9(a)(ii) and the Target Pre-Retirement Death Benefit determined as of the Progress Nonqualified Plan Participant’s actual date of death under Section 6.9(d)(ii), the Final Average Salary (as
determined above) shall be increased by the increase in the Consumer Price Index –Urban Wage Earners and Clerical Workers (“CPI-W”) for the period from the Progress Merger Effective Time to the earliest to occur of the Progress
Nonqualified Plan Participant’s death, Separation from Service, Progress Early Retirement Date, or Progress Normal Retirement Date, whichever is applicable. 
 Frozen Progress Nonqualified Plan Benefit. Shall mean the Normal Retirement Benefit, Early Retirement Benefit or Deferred Vested Benefit, as applicable, determined under Paragraph 1, 2 or 3, as
applicable, of this Exhibit A as if the Progress Nonqualified Plan Participant incurred a Separation from Service as of the Progress Merger Effective Time, subject, however, to the following: 

 

	(I)	If the Progress Nonqualified Plan Participant is eligible for an Early Retirement Benefit under Paragraph 2 of Exhibit A at the time that the Progress Nonqualified Plan
Participant’s benefit commences, the reduction (if any) for commencement prior to the Progress Nonqualified Plan Participant’s 65th birthday shall be determined as provided in Exhibit A at the time that the Progress Nonqualified Plan
Participant’s benefit commences. 

  

	(II)	The Progress Nonqualified Plan Participant’s marital status (and payment form) shall be determined at the time that the Progress Nonqualified Plan
Participant’s benefit commences. 

  

	(III)	The Assumed Deferred Vested Pension Benefit, Assumed Early Retirement Pension Benefit or Assumed Normal Retirement Pension Benefit, as applicable, shall be determined
as of the Progress Merger Effective Time and without regard to the limitations imposed by Section 415 of the Code with respect to the Progress Qualified Retirement Plan. 

 

	(IV)	For purposes of clarity, the Progress Nonqualified Plan Participant’s Final Average Salary, Service, Social Security Benefit, and, except to the extent provided in
(I) and (II), eligibility for a Normal Retirement Benefit, Early Retirement Benefit, or Deferred Vested Benefit, as applicable, shall be determined as of the Progress Merger Effective Time. 

Minimum Progress Nonqualified Plan Benefit. Shall mean the Normal Retirement Benefit, Early Retirement Benefit or Deferred Vested Benefit, as
applicable, determined under this Exhibit A as of the time of the Progress Nonqualified Plan Participant’s actual Separation from Service, subject to the following: 

  
 24 

	(I)	The Progress Nonqualified Plan Participant’s Final Average Salary shall be determined as provided in this Exhibit A (for purposes of clarity, determined at the
Progress Merger Effective Time and as adjusted for cost of living from the Progress Merger Effective Time to the earliest to occur of the Progress Nonqualified Plan Participant’s death, Separation from Service, Progress Early Retirement Date,
or Progress Normal Retirement Date, whichever is applicable). 

  

	(II)	The Progress Nonqualified Plan Participant’s Assumed Deferred Vested Pension Benefit, Assumed Early Retirement Pension Benefit or Assumed Normal Retirement Pension
Benefit, as applicable, shall be determined at the time of the Progress Nonqualified Plan Participant’s actual Separation from Service. 

  

	(III)	The Progress Nonqualified Plan Participant’s marital status (and payment form) shall be determined at the time that the Progress Nonqualified Plan
Participant’s benefit commences. 

  

	(IV)	For purposes of clarity, the Participant’s Service, Social Security Benefit, and eligibility for a Normal Retirement Benefit, Early Retirement Benefit or Deferred
Vested Benefit, as applicable, shall be determined as of the time of the Progress Nonqualified Plan Participant’s actual Separation from Service. 

 Progress Early Retirement Date. Shall mean the date on which a Progress Nonqualified Plan Participant who qualifies for the early retirement benefit of Paragraph 2 of this Exhibit A retires from
