 Buckeye Pipe Line Services Company 

Benefit Equalization Plan 
 Preamble 
 Effective as of January 1, 1990, Buckeye Pipe Line Company
established this Buckeye Pipe Line Company Benefit Equalization Plan (the predecessor to the Buckeye Pipe Line Services Company Benefit Equalization Plan) (the “Plan”). The Plan is intended to be an excess benefit plan with respect to
benefits in excess of the limitations imposed by section 415 of the Internal Revenue Code of 1986, as it may be amended from time to time (the “Code”), and is also intended to provide benefits in excess of the limitations imposed by
section 401(a)(17) of the Code, for employees of Buckeye Pipe Line Company participating in the Buckeye Pipe Line Company Retirement and Savings Plan (the predecessor to the Buckeye Pipe Line Services Company Retirement and Savings Plan) (the
“RASP”), the Buckeye Pipe Line Company Retirement Income Guarantee Plan (the predecessor to the Buckeye Pipe Line Services Company Retirement Income Guarantee Plan) (the “RIGP”) and, effective March 22, 1996, the BMC
Acquisition Company Employee Stock Ownership Plan (the predecessor to the Buckeye Pipe Line Services Company Employee Stock Ownership Plan) (the “ESOP”). The employees of Buckeye Pipe Line Company eligible to participate in the Plan became
employees of Buckeye Pipe Line Services Company (the “Company”), effective March 22, 1996, and the Company became the successor to Buckeye Pipe Line Company as of that date. 

The RASP, the RIGP and the ESOP are qualified plans under section 401(a) of the Code. The Plan is not a qualified plan under the Code,
and benefits hereunder will not be funded for purposes of ERISA or the Code but will be paid out of the general assets of the Company. The rights of any person to receive benefits under this Plan are limited to those of a general creditor of the
Company. The Plan was amended and restated effective January 1, 2002 and such changes apply only to Participants whose Severance Date occurs on or after January 1, 2002. All other Participants’ rights shall be determined in accordance
with the Plan as in existence on December 31, 2001. The Plan was further amended and restated, effective January 1, 2003, to allow Participants whose pre-tax and after-tax contributions to the RASP are limited by section 415 of the Code to
defer such contributions to the Plan and again effective January 1, 2005, to comply with section 409A of the Code. Amendment No. 2011-1 to the Plan was adopted on November 3, 2011 to permit the transfer of benefits under the Plan
pursuant to a qualified domestic relations order. The Plan is now amended and restated effective January 1, 2012 to reflect the freezing of the ESOP, incorporate Amendment No. 2011-1 and make certain other clarifying changes.

 ARTICLE II 
 BEP Benefits 

2.1. BEP Savings Benefit 
 (a) An Eligible Employee’s BEP Savings Benefit, if any, shall be equal, to the sum of (1) and (2) below, determined in the following manner: 

(1) Employer Contribution Credits. Amounts will be credited to an Eligible Employee’s account or accounts under the Plan as
of the end of any payroll period for which the amount contributed to his accounts in the RASP is curtailed as a result of any of the following: 

  
 3 

 (A) the application of the Section 415 Limitation; 

(B) the application of the Compensation Limitation. 
 The amount so credited shall equal the Employer contribution (including contributions to his Retirement Account and Company Matching Contributions) that would be contributed for the Eligible Employee for
such payroll period if there had been no such curtailment, minus the amount of the actual Employer contributions made on his behalf for such payroll period; provided, however, that, in determining the amount to be credited, there shall be excluded
from the Eligible Employee’s earnings any amounts that are imputed to the Eligible Employee under the Code because of the provision of fringe and welfare benefits to the Eligible Employee by the Company and any other amounts paid to the
Employee on account of the imputation of earnings on such benefits to satisfy the Eligible Employee’s tax obligations. 

(2) Deemed Earnings. An additional amount representing deemed earnings on the hypothetical investment of the amounts prescribed in
(1) above, with such hypothetical investments to be determined, and such deemed earnings to be calculated, in the manner set forth in Section 2.1(b) below. 
 (b) An unfunded account or accounts shall be established for each Eligible Employee to determine the amount payable on his behalf under the Plan. Unless otherwise determined by the Committee, the
hypothetical investments shall be the same Funds (or any other investment approved by the Committee) as are available under the RASP from time to time. A separate account shall be established for such hypothetical investment. As of the last day of
each calendar month (or, in the discretion of the Committee, as of more frequent valuation dates), the balance in the account shall be adjusted to reflect (i) Plan contributions deemed credited under the Plan on behalf of the Participant since
the last preceding valuation date and (ii) the earnings or losses (whether or not realized) that would have occurred since such valuation date if the prior balance on such valuation date (reduced by the Plan distributions described in Article
IV below) had been invested in the applicable hypothetical investment in the same proportions as the Eligible Employee invests his or her accounts under the RASP. The Committee may at any time adopt uniform rules to administer these or other Plan
provisions. The Committee may also terminate any hypothetical investment or investments under the Plan (after notice to affected Eligible Employees), in which event the account balance relating to such terminated investment shall be considered
transferred to another investment account established for the Eligible Employee (which other investment shall be selected by the Committee). A statement showing his hypothetical account balance shall be distributed to each Participant from time to
time by the Committee (at least once a year and at such additional times as the Committee shall determine in its discretion). 

2.2. BEP Retirement Benefit. 
 An Eligible Employee’s BEP Retirement Benefit, if any, shall be determined as if it were payable as Normal Retirement Income (as described in Section 3.1 of the RIGP) commencing at Normal
Retirement Date in the form of a single life annuity and shall be equal to (1) minus (2), where: 

  
 4 

 (1) is the vested portion of the Basic Benefit determined pursuant to the formula contained
in Section 3.1 of the RIGP in the form of a single life annuity commencing at Normal Retirement Date; provided, however, that such determination shall be made without taking into account the Section 415 Limitation of the RIGP or the
Compensation Limitation of the RIGP; and 
 (2) is the sum of the following components, each expressed in the form of a single
life annuity commencing at Normal Retirement Date: (i) the Participant’s Combined Benefit Offset (as defined in Article I of the RIGP); (ii) the Normal Retirement Income payable to the Participant under Section 3.1 of the RIGP;
and (iii) the Actuarial Equivalent of the vested portion of the Participant’s BEP Savings Benefit attributable to Employer Contribution Credits (under Section 2.1(a)(1) above) in respect of his Retirement Account curtailed under the
RASP; provided, however, that, in determining the BEP Retirement Benefit, there shall be excluded from the Eligible Employee’s earnings any amounts that are imputed to the Eligible Employee under the Code because of the provision of fringe and
welfare benefits to the Eligible Employee by the Company and any other amounts paid to the Eligible Employee on account of the imputation of earnings on such benefits to satisfy the Eligible Employee’s tax obligations. 

This Section 2.2 shall only apply to persons who participate in the RIGP. 
 2.3. BEP ESOP Benefit. Effective March 27, 2011, the ESOP was frozen and no further contributions shall be credited under the ESOP other than dividends on shares held under the ESOP in
accordance with the terms thereof. 
 (a) An Eligible Employee’s BEP ESOP Benefit, if any, shall be equal to the sum of
(1) and (2) below, determined in the following manner: 
 (1) Employer Contribution Credits. Amounts will be
credited to an Eligible Employee’ s account under the Plan as of the end of any calendar quarter for which the amount contributed to his accounts in the ESOP is curtailed as a result of any of the following: 

(A) the application of the Section 415 Limitation; 
 (B) the application of the Compensation Limitation. 
 The amount so credited shall equal the
Employer contribution (including dividends that would otherwise be credited to his account) that would be contributed for the Eligible Employee for such allocation period if there had been no such curtailment, minus the amount of the actual Employer
contributions made on his behalf for such allocation period; provided, however, that, in determining the amount to be credited, there shall be excluded from the Eligible Employee’s earnings any amounts that are imputed to the Eligible Employee
under the Code because of the provision of fringe and welfare benefits to the Eligible Employee by the Company and any other amounts paid to the Employee on account of the imputation of earnings on such benefits to satisfy the Eligible
Employee’s tax obligations. 

  
 5 

 (2) Deemed Investment. The amount contributed shall be deemed to be invested in
shares of common stock or preferred stock convertible into common stock of the Company or whatever employer security is the principal investment of the ESOP as the same may be changed from time to time. The appreciation of any dividends paid on such
shares shall represent deemed earnings on the hypothetical investment of the amounts prescribed in (1) above, with such hypothetical investments to be determined, and such deemed earnings to be calculated, in the manner set forth in
Section 2.1(b) below. 
 (b) An unfunded account shall be established for each Eligible Employee to determine the amount
payable on his behalf under the Plan. Unless otherwise determined by the Committee, the hypothetical investments shall be the same shares of stock as are available under the ESOP or such other investment alternatives as are made available under the
ESOP from time to time. A separate account shall be established for such hypothetical investment. As of the last day of each allocation period (or, in the discretion of the Committee, as of more frequent valuation dates), the balance in the account
shall be adjusted to reflect (i) Plan contributions deemed credited under the Plan on behalf of the Participant since the last preceding allocation period and (ii) the earnings or losses (whether or not realized) that would have occurred
since such valuation date if the prior balance on such valuation date (reduced by the Plan distributions described in Article IV below) had been invested in the hypothetical investments as is invested for the Eligible Employee’s account under
the ESOP. The Committee may at any time adopt uniform rules to administer these or other Plan provisions. A statement showing his hypothetical account balance shall be distributed to each Participant from time to time by the Committee (at least once
a year and at such additional times as the Committee shall determine in its discretion). 
 2.4. Entitlement to BEP ESOP
Benefit, BEP Savings Benefit and BEP Retirement Benefit. 
 Except as set forth in clause (2)(iii) of Section 2.2
above and the next following sentence, the entitlement of a Participant to a benefit under Section 2.1, 2.2 or 2.3, as the case may be, shall not in any way preclude or otherwise offset any benefit to which such Participant is entitled under
the other Section. However, if the amount in clause (2) of Section 2.2 above would otherwise exceed the amount in clause (1) of Section 2.2 above (so that such clause (1) amount minus such clause (2) amount is a
negative number) then the amount credited under clause (a) (1) of Section 2.1 in respect of his Retirement Account shall be reduced by the lesser of (i) such excess or (ii) the amount of his actual RIGP accrued benefit
payable in the form of a lump sum (but no reduction shall be made in the amount credited under clause (a) (1) of Section 2.1 in respect of his Company Matching Contribution Account). 

2.5. Restoration of Credited Service. 
 If a Participant is reemployed by the Employer after having received payments of his BEP Retirement Benefit under the Plan, such Participant’s subsequent BEP Retirement Benefit shall be reduced by an
amount that is the Actuarial Equivalent, at the time of the previous payment, of the amount of the BEP Retirement Benefit previously paid. 

  
 6 

 ARTICLE III 
 Vesting of BEP Benefits 
 3.1. BEP Savings Benefit. 

A Participant shall become vested in his Employer Contribution Credits in accordance with the same schedules and rules as are applicable
in determining when he becomes vested in his Retirement Account and Company Matching Contribution Account under the RASP. 

3.2. BEP Retirement Benefit. 
 A Participant shall become vested in his BEP Retirement Benefit in accordance with the same schedules and rules as are applicable in determining when he becomes vested in his accrued benefit under the
RIGP. 
 3.3. BEP ESOP Benefit. 
 A Participant shall become vested in his BEP ESOP Benefit in accordance with the same schedules and rules as are applicable in determining when he becomes vested in his account under the ESOP. 

3.4. Forfeitures. 
 Any amount forfeited by a Participant who does not become fully vested in a benefit under this Plan shall constitute a reduction of the Employer’s liability under the Plan and shall not be allocated
to the remaining Participants. 
 ARTICLE IV 
 Time and Form of Payment of BEP Savings, Retirement and ESOP Benefits 

4.1. Termination of Employment  
 A Participant’s BEP Savings and ESOP Benefits, and the Actuarial Equivalent of his BEP Retirement Benefit, shall be paid to the Participant in a lump sum as soon as practicable following his
Severance Date, but in no event later than the ninetieth day following his Severance Date. 
 4.2. Small Accounts. The
Committee may, in its sole discretion, distribute in a single lump sum the aggregate amount of a Participant’s BEP Savings and ESOP Benefits, and the Actuarial Equivalent of his BEP Retirement Benefit credited to the Plan on the
Participant’s behalf; provided: (i) the payment results in the payment of the Participant’s entire interest in his benefit under the Plan and all other plans required by section 409A of the Code to be aggregated with the
Participant’s benefit under the Plan and (ii) the total payment does not exceed the applicable dollar limit under section 402(g)(1)(B) of the Code. The Board shall notify the Participant in writing if the Board exercises its
discretion pursuant to this Section.

  
 7 

 4.3. Change of Form of Payment in Event of Hardship. 

At any time before the payment of a Participant’s BEP Savings Benefit or BEP Retirement Benefit pursuant to Section 4.1 above
(or after or before commencement of payment of a BEP Death Benefit under Article V below), a Participant may request payment of the Participant’s benefit or remaining amount of his benefit in a lump sum subject to a determination by the
Committee that the Participant (or Beneficiary) has or will experience an unforeseeable emergency which arises from factors beyond the Participant’s (or Beneficiary’s) control and creates a severe financial hardship that results from an
illness or accident of the Participant (or Beneficiary), the Participant’s (or Beneficiary’s) spouse or the Participant’s (or Beneficiary’s) dependent (within the meaning of section 152(a) of the Code), loss of the
Participant’s (or Beneficiary’s) property due to casualty, or other similar extraordinary and unforeseeable circumstances. In the event of such a determination, the acceleration of the benefit payment shall be made only to the extent and
in an amount necessary to provide for such hardship, plus amounts necessary to pay reasonably anticipated taxes resulting from the distribution. A hardship acceleration shall not be made to the extent the hardship may be relieved through
reimbursement or compensation by insurance or otherwise, or by liquidation of the Participant’s (or Beneficiary’s) other assets to the extent such liquidation would not itself cause severe financial hardship. In the event of such an
acceleration, payment of the appropriate amount (as determined by the Committee) shall be made as soon as practicable to the Participant (or Beneficiary), but not later than the later of the last day of the calendar year in which the Committee
determines the hardship occurred or the ninetieth day following the date the Committee determines the hardship occurred, first from his BEP Savings Benefit and then from his BEP Retirement Benefit, if necessary. Any amounts of such benefit not so
accelerated (actuarially reduced to reflect the value of the acceleration) shall continue to be paid as and when otherwise due. 

ARTICLE V 

BEP Death Benefit 
 5.1. BEP Savings Death Benefit. 
 In the event of a Participant’s death
before a complete distribution of his BEP Savings Benefit has been made, a death benefit equal to the unpaid balance of the deceased Participant’s BEP Savings Benefit shall be payable to his Beneficiary in the form of a lump sum. Such payment
shall be made not later than the ninetieth day following the Participant’s death. 
 5.2. BEP Retirement Death
Benefit. 
 (a) Upon the death of a married Participant before his Benefit Commencement Date (as defined in Article I of the
RIGP), a benefit under this Plan shall be paid to his surviving spouse if such spouse is entitled to a benefit under Section 3.5 of the RIGP. Such spouse’s benefit shall be payable in the form of a single life annuity for the life of the
spouse beginning as of the earliest date benefits may be payable under such Section 3.5 of the RIGP and shall be equal to (1) the amount that would have been payable to such spouse under Section 3.5 of the RIGP if the RIGP were not
subject to the Section 415 

  
 8 

 
Limitation or the Compensation Limitation, minus (2) the amount payable to such spouse under Section 3.5 of the RIGP, determined as of the earliest date any such amount may be payable
under such Section 3.5. No death benefits are payable upon the death of an unmarried Participant. 
 (b) Notwithstanding the
foregoing, the benefit due under Section 5.2(a) shall be paid in the form of a lump sum which is the Actuarial Equivalent of the spousal benefit under Section 5.2(a) if such Actuarial Equivalent distribution would not exceed $25,000 as of
the date of the Participant’s death. Such payment shall be made not later than the ninetieth day following the Participant’s death. 
 5.3. Participant’s Right to Designate Beneficiary of BEP Retirement Death Benefits.  
 Notwithstanding the foregoing, a Participant may, by a notice in writing filed with the Committee at any time prior to his death, designate any person or persons (including his estate) as the beneficiary
of any BEP Retirement Benefits due under Section 5.2 after his death (without regard to whether the amount or time of payment of benefits is dependent on the lifetime or circumstances of any individual other than the person so designated). Any
such designation may be changed by the Participant at any time, by a similar notice, without the consent of any other person. A beneficiary designation hereunder shall not have any effect on the amount or duration of BEP Retirement Benefit payments
payable under this Plan after the Participant’s death and shall affect only the identity of the person to whom payments are made. 
 5.4. BEP ESOP Death Benefit. 
 In the event of a Participant’s death
before distribution of his BEP ESOP Benefit has been made, a death benefit equal to the balance of the deceased Participant’s BEP ESOP Benefit shall be payable to his Beneficiary in the form of a lump sum. Such payment shall be made no later
than the ninetieth day following the Participant’s death. 

  
 9 

 ARTICLE VI

 6.1. Operation of the Committee.

 (a) The Committee shall act by a majority of its members constituting a quorum and such action may be taken either by a vote
in a meeting or in writing without a meeting. A quorum shall consist of a majority of the members of the Committee. No Committee member shall act upon any question pertaining solely to himself, and with respect to any such question only the other
Committee members shall act. 
 (b) The Committee may allocate responsibility for the performance of any of its duties or powers
to one or more Committee members by unanimous written resolution executed by every Committee member. Any such resolution shall remain in effect until rescinded by a majority of the Committee members. 

(c) The Committee shall keep a record of its proceedings and acts and shall keep such books of account, records and other data as may be
necessary for the proper administration of the Plan. 
 6.2. Powers and Duties of the Committee. 

The Committee shall be generally responsible for the operation and administration of the Plan. To the extent that powers are not delegated
to others pursuant to provisions of this Plan, the Committee shall have such powers as may be necessary to carry out the provisions of the Plan and to perform its duties hereunder, including, without limiting the generality of the foregoing, the
discretionary power: 
 (a) To appoint, retain, and terminate such persons as it deems necessary or advisable to assist in the
administration of the Plan or to render advice with respect to the responsibilities of the Committee under the Plan, including accountants, actuaries, administrators, attorneys and physicians. 

(b) To make use of the services of the Company in administrative matters. 

(c) To obtain and act on the basis of all tables, valuations, certificates, opinions, and reports furnished by the persons described in

Plan administration have been handled by the Company. 
 (e) In its discretion, to determine all benefits (including, but not
limited to, determination of an individuals eligibility for Plan participation, the right to and amount of any benefit payable under the Plan and the date on which any individual ceases to be a Participant) and resolve all questions, including
factual questions, pertaining to the administration, interpretation and application of the Plan provisions, either by rules of general applicability or by particular decisions. Determinations made by the Committee shall be final and binding.

  
 10

 (h) To commence or defend any litigation arising from the operation of the Plan in any legal or administrative proceedings. 
 (i) To establish procedures in accordance with section 414(p) of the Code to determine the qualified status of domestic relations orders and to administer distributions under such qualified domestic

 As soon as reasonably practicable after the end of each year, or more frequently as determined by the Committee, in its sole discretion, the Committee shall provide each Participant with a statement
showing his credited BEP Saving Benefit, BEP ESOP Benefit and his accrued BEP Retirement Benefit, and may, in its discretion, provide a Participant or Beneficiary with such other material as he requests in writing, in which case the Committee, in
its discretion, may require the Participant or Beneficiary to pay the reasonable cost of preparing and furnishing such material. 
 6.4. Required Information. 
 Any Participant and any Beneficiary eligible to
receive benefits under the Plan shall furnish to the Committee any information or proof requested by the Committee and reasonably required for the proper administration of the Plan. Failure on the part of the Participant or Beneficiary to comply
with any such request within a reasonable period of time and in good faith shall be sufficient grounds for delay in the payment of benefits under the Plan until such information or proof is received by the Committee. 

6.5. Compensation and Expenses. 
 All expenses incident to the operation and administration of the Plan reasonably incurred, including, without limitation by way of specification, the fees and expenses of attorneys and advisors, and for

initial 90-day period and (ii) if the claimant has not received written notice of such decision within such initial 90-day period (or within the additional 90-day period if special circumstances apply), the claimant shall, for the purpose of
subsection (c) of this Section, regard his claim as having been denied.

to special circumstances (such as, for example, the need to hold a hearing) to extend this period and so notifies the claimant in writing, the decision shall be rendered as soon as practical, but in no event later than 120 days after the
claimant’s request for review. Any such decision shall be final and binding.

 ARTICLE VII 
 Miscellaneous 
 7.1. Benefits Payable by the Company. 

 
 The Company shall bear the cost of the benefits provided hereunder
with respect to persons who were employed by it, based on records maintained by the Company. The obligations of the Company hereunder shall not be funded in any manner for purposes of ERISA or the Code. The rights of any person to receive benefits
under this Plan are limited to those of a general creditor of the Company liable for such benefits hereunder. Consistent with the foregoing, the Company may in its discretion deposit funds in a grantor trust or otherwise establish arrangements to
pay amounts that become due under the Plan, and, notwithstanding anything elsewhere in the Plan, the benefits due under the Plan shall be actuarially reduced to reflect the value of any payment made to any person covered by the Plan from a grantor
trust or other arrangement established for this purpose by the Company. 
 7.2. Amendment or Termination. 

(a) The Board reserves the right to amend, alter, modify, restate, terminate or partially terminate the Plan at any time and from time to
time to any extent that it may deem advisable; provided, however, that, subject to applicable bankruptcy laws, no such action by the Board shall reduce a Participant’s BEP Savings Benefit, BEP ESOP Benefit or BEP Retirement Benefit credited or
accrued, as the case may be, as of the time such action is taken, nor may any such action adversely affect the vesting schedule applicable to a Participant without his consent. 
 (b) If the Plan is terminated, a distribution shall be made of the Participant’s BEP Savings Benefit, BEP ESOP Benefit and BEP Retirement Benefit as of the Plan termination date (determined in
accordance with Section 7.2 (a) above). The amount of such benefit or benefits shall be payable to the Participant at the time it would have been payable under Article IV above if the Plan had not been terminated. If an active Participant
dies after termination of the Plan but prior to severance and prior to payment of his BEP Savings Benefit or BEP ESOP Benefit, his Beneficiary or Beneficiaries shall receive a distribution of his BEP Savings Benefit or BEP ESOP Benefit as of the
date of death in accordance with Sections 5.1 and 5.4 above. After termination of the Plan, no death benefit shall be payable under Section 5.2 above, but the Beneficiary of a Participant will receive a lump sum payment that is the Actuarial
Equivalent of the Participant’s BEP Retirement Benefit if the Participant’s BEP Retirement Benefit had not been paid to him before his death (with any such death benefit to be based on the Participant’s BEP Retirement Benefit accrued
as of the Plan termination date). Any such payment shall be at the time otherwise prescribed in Section 5.2(a) or (b), whichever would otherwise be applicable. Any amounts payable under this Section 7.2(b) shall be credited annually with
earnings at the RASP Fund Rate, from the Plan termination date until the payment date. 
 (c) Notwithstanding any provision in
Article IV to the contrary, in the event that the RASP, ESOP or RIGP is terminated, but the Board does not direct that the Plan be terminated, the Plan shall be continued for BEP Savings, ESOP and Retirement Benefits then accrued. 

  
 14 

 7.3. Status of Employment. 

Nothing herein contained shall be deemed: (a) to give to any Participant the right to be retained in the employ of the Company or a
subsidiary or affiliate; (b) to affect the right of the Company to discipline or discharge any Participant at any time; (c) to give the Company or a subsidiary or affiliate the right to require any Participant to remain in its employ; or
(d) to affect any Participant’s right to terminate his employment at any time. 
 7.4. Payments to Minors and
Incompetents. 
 If a Participant or Beneficiary entitled to receive any benefits hereunder is a minor or is deemed by the
Committee or is adjudged to be legally incapable of giving a valid receipt and discharge for such benefits, they will be paid to the fully appointed guardian of such minor or incompetent or to such other legally appointed person as the Committee may
designate. Such payment shall, to the extent made, be deemed a complete discharge of any liability for such payment under the Plan. 
 7.5. Inalienability of Benefits. 
 Except as provided in Section 7.6
with respect to domestic relations orders, the benefits provided hereunder will not be subject to voluntary or involuntary transfer, alienation assignment, garnishment, attachment, execution or levy of any kind, either voluntarily or involuntarily,
and any attempt to cause such benefits to be so subjected will not be recognized, except to such extent as may be required by law. In the event a person who is receiving or is entitled to receive benefits under the Plan attempts to assign, transfer
or dispose of such right, or if any attempt is made to subject said right to such process, such assignment, transfer or disposition shall be null and void. 
 7.6. Treatment of Domestic Relations Orders. 
 (a) The prohibitions
contained in Section 7.5 shall not apply to payments or transfers made pursuant to a domestic relations order which complies with the provisions of this Section. 
 (b) The Plan will comply with a domestic relations order, provided it meets the following conditions: 
 (1) The domestic relations order must be a judgment, decree, or order made by a court pursuant to a state domestic relations law. 
 (2) The domestic relations order must relate to the payment of a marital property award to a spouse or former spouse of a Participant (an “Alternate Payee”). 

(3) The domestic relations order, as described in paragraphs (1) and (2) above, must create or recognize an Alternate Payee as
an owner or a co-owner of an interest of a Participant under the Plan, must specifically identify each interest that is subject to such order and must specifically order the direct transfer of each such interest to such Alternate Payee. 

  
 15 

 (4) No domestic relations order shall require the Plan (A) to provide any type or form
of benefit not otherwise provided by the Plan; nor (B) to provide any increased benefits; nor (C) to pay benefits to an Alternate Payee which are required to be paid to another Alternate Payee under another previously applicable domestic
relations order. 
 (c) The Committee shall establish procedures to determine whether a domestic relations order is qualified and
to administer distributions under such domestic relations order. 
 (d) The Committee may, in its sole and absolute direction,
accelerate the time or schedule of a payment under the Plan to an Alternate Payee as may be necessary to fulfill a domestic relations order. 
 (e) Any benefits payable or interest transferred under this Section 7.6 pursuant to a domestic relations order shall be computed before determining the benefit payable under any other Section of the
Plan, and shall reduce the amount payable under the Plan.” 
 7.7. Governing Law. 

Except to the extent preempted by federal law, the Plan shall be governed by and construed in accordance with the laws of the Commonwealth
of Pennsylvania.

following: 
 (b) As a condition to receiving any Shares upon vesting of the RSUs, on the date of this Agreement, the
Participant hereby irrevocably instructs the Company to take the actions described in this subsection 6(b). On each Vesting Date, the Participant hereby elects to satisfy all Withholding Taxes obligation then due through the retention by the Company
of Shares. Accordingly, the Participant hereby instructs the Company, with no further action by the Participant, on each Vesting Date to deduct and retain from the number of Shares to which the Participant is entitled from the RSUs then scheduled to
vest such number of Shares as is equal to the value of the Withholding Taxes. The Participant understands that the fair market value of the surrendered Shares will be based on the closing price of the Company’s Common Stock on the trading day
preceding the Vesting Date. 
 (c) Participant has reviewed with the Participant’s own tax advisors the federal, state,
local and foreign tax consequences of this grant and the transactions contemplated by this Agreement. The Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. The

(d) The Participant represents to the Company that, as of the date hereof, he/she is not aware of any material nonpublic information
about the Company or the Common Stock. The Participant and the Company have structured this Agreement to constitute a “binding contract” relating to the retention by the Company of Common Stock pursuant to this Section 6, consistent
with the affirmative defense to liability under Section 10(b) of the Securities Exchange Act of 1934 under Rule 10b5-1(c) promulgated under such Act. 
 7. Nature of the Grant. In signing this Agreement, the Participant acknowledges that: 
 (a) the Plan is established voluntarily by the Company, it is discretionary in nature and may be modified, amended, suspended or terminated by the Company at any time, unless otherwise provided in the
Plan and this Agreement; 
 (b) the grant of RSUs is voluntary and occasional and does not create any contractual or other right
to receive future awards of RSUs, or benefits in lieu of RSUs even if RSUs have been awarded repeatedly in the past; 

  
 4 

 (c) all decisions with respect to future grants of RSUs, if any, will be at the sole
discretion of the Company; 
 (d) the Participant’s participation in the Plan is voluntary; 

(e) RSUs are an extraordinary item that do not constitute compensation of any kind for services of any kind rendered to the Company or to
the Participant’s employer, and RSUs are outside the scope of the Participant’s employment contract, if any; 
 (f)
RSUs are not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculation of any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or
retirement benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Company or the Participant’s employer; 

(g) the future value of the underlying Shares is unknown and cannot be predicted with certainty; 

(h) if the Participant receives Shares upon vesting, the value of such Shares acquired on vesting of RSUs may increase or decrease in
value; 
 (i) in consideration of the grant of RSUs, no claim or entitlement to compensation or damages arises from termination
of the RSUs or diminution in value of the RSUs or Shares received upon vesting of RSUs resulting from termination of the Participant’s employment by the Company or the Participant’s employer (for any reason whatsoever and whether or not in
breach of local labor laws) and the Participant irrevocably releases the Company and his or her employer from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have
arisen, then, by signing this Agreement, the Participant shall be deemed irrevocably to have waived his or her entitlement to pursue such claim; and 
 (j) further, if the Participant ceases to be a employee (whether or not in breach of local labor laws), the Participant’s right to receive RSUs and vest under the Plan, if any, will terminate
effective as of the date that the Participant is no longer actively employed by the Company and will not be extended by any notice period mandated under local law (e.g., active employment would not include a period of “garden leave”
or similar period pursuant to local law); the Committee shall have the exclusive discretion to determine when the Participant is no longer actively employed for purposes of the Plan. 

8. Data Privacy Notice and Consent. The Participant hereby explicitly and unambiguously consents to the collection, use and

purposes described in this section, including any requisite transfer to Broker or such other stock plan service provider or other third party as may be required for the administration of the Plan and/or the subsequent holding of Shares of stock on

 Grant Date: 

Restricted Stock Units Granted: <<NumShares>> (“Target Number of RSUs”) 

Subject to the terms and conditions of this Agreement (including the Forfeiture provisions described in Section 2 above and the performance criteria
listed below), the RSUs shall vest in three (3) equal installments as follows: (a) the first third will vest upon the later of (i) the Determination Date (defined below) or (ii) the first anniversary of the Grant Date;
(b) an additional one third will vest on the second anniversary of the Grant Date, and (c) the final one third will vest on the third anniversary of the Grant Date. The date upon which each such installment vests shall be considered a
“Vesting Date” for the portion of the RSUs vesting on that date. 
 The table below will determine the number of RSUs the Participant
will be entitled to receive, subject to the vesting period described above and Forfeiture and other restrictions contained in this Agreement. The “Determination Date” shall be the date that the Company publicly announces its financial
results for the relevant period referenced in the table below. If the Participant ceases to be employed by the Company by reason of death, Disability or Retirement, the performance portion of the shares shall be determined per the
