	1A.	TRANSITION OF MANUFACTURING 

 1A.1 Move. The parties have agreed that Entegris will move its membrane manufacturing operations currently conducted in the
Premises to the New Entegris Facility in an orderly manner (the “Move”) during the Facility Term. 
 1A.2
Timing. Entegris will not move any equipment or operations sooner than July 2009. Subject to the achievement of required safety stocks as described in Section 5.7, Entegris will complete the Move and have vacated the
Premises no later than the end of the Facility Term. Entegris will prepare a detailed move schedule and provide it to Millipore by December 31,2008 .The parties will review and update the schedule during the Facility Term on a monthly basis as
the Move progresses. Millipore will supply its requirements for feasibility and qualification rolls in coordination with the schedule. 
 1A.3 Coordination. The parties will work together in good faith to facilitate such Move to minimize disruptions and costs to both parties. 
 1A.4 Qualification. Prior to the reduction or cessation of production of Membranes at the Premises, Entegris will establish
its own new UPE annealing capability at the New Entegris Facility. Millipore will use its commercially reasonable efforts, in conjunction with Entegris, to qualify the Entegris’ manufacturing process at the New Entegris Facility to enable the
supply of qualified Membranes. Entegris will provide to Millipore in parallel with such qualification a reasonable quantity of rolls of UPE Membrane necessary for Millipore to conduct feasibility and qualification testing. All such feasibility and
evaluation rolls provided to Millipore by Entegris will meet all existing Entegris specifications as agreed by the parties. If, despite each party’s commercially reasonable efforts, Millipore is unable to qualify the Entegris UPE annealing
line, Millipore reserves the right to perform the annealing process itself. In such circumstances, Entegris shall provide to Millipore a sufficient quantity of extracted gel rolls, at appropriately adjusted prices, to enable Millipore to produce
sufficient finished product to meet Entegris’ obligations for such finished product. 
  

 Page 5 of 28 

 1A.5 No Supply Disruption. Notwithstanding the Move, Entegris will at all
times during the Term of this Agreement continue to meet its supply obligations to Millipore under this Agreement of any Membranes from a manufacturing process qualified by Millipore. It is the expectation of the parties that Entegris will produce
Membranes from both facilities initially and, after the Facility Term, if the New Entegris Facility and its processes are qualified by Millipore, solely from the New Entegris Facility. 
 1A.6 No VMF4 Disruption. Notwithstanding the Move, Millipore will at all times during the Term of this Agreement continue to
meet its obligations to Entegris under this Agreement to provide hydrophilization of any Membranes on its VMF4 Line. 
 1A.7
Costs. Entegris will bear all costs of dismantling, packaging, freight, shipping, installation, testing and requalification of all Entegris Equipment to be removed from the Premises. 
 1A.8 Transfer to New Annealing Line. If Entegris’ new UPE annealing process can be qualified successfully by Millipore as
provided above,, then after such qualification Millipore shall have Millipore membrane processed by Entegris on the new Entegris annealing machine with pricing based on the costs associated with the new machine and forego any payment for existing
Film I Annealing machine hours from Entegris. Prior to any successful qualification of such new process to Millipore’s reasonable satisfaction, Millipore shall have Millipore membrane continue to be processed on the existing Film I annealing
machine at the Premises with Entegris continuing to be charged the same rates and pricing then in effect. Any such shifting of production shall not result in a termination of the Agreement, which may be only be terminated in accordance with its
terms. 
  

	2.	LEASE OF THE PREMISES 

 In order to enable Entegris to manufacture UPE Membranes, including Treated Flat Sheet UPE Membranes and Other Flat Sheet UPE Membranes, and Treated Other
Entegris Membranes in the same production areas at Millipore’s facility at 80 Ashby Road, Bedford MA. and/or such additional, reduced or substituted areas all as described in greater detail in Exhibit B hereto, and with the same processes as
such UPE Membranes and Treated Other Entegris Membranes were manufactured prior to the Effective Date (both (i) for its own use and sale and for its sale of UPE Products and (ii) for supply of Flat Sheet UPE Membranes to Millipore as
provided in this Agreement), Millipore and Entegris agree to the arrangements regarding Entegris’ use of the Premises as are set forth in Exhibit B hereto for the duration of the Facility Term.

Move, Entegris will make all commercially reasonable efforts to maintain the Safety Stock at such amount. 
 5.7.3 The level of
existing Safety Stock as of the Effective Date is 144,235 feet. The parties agree that production in any calendar quarter in excess of, or below, 200,000 feet shall increment or decrement, respectively, the amount of Safety Stock. In addition,
material returns for verified quality issues related to the portions of the process controlled by Entegris will reduce the amount of Safety Stock, foot for foot. The parties will review the amount of Safety Stock on a monthly basis and will mutually
determine when the Safety Stock has reached 400,000 feet. The parties acknowledge that the Safety Stock described in this section is exclusively for the benefit of Millipore’s supply needs. Millipore will provide the necessary storage space for
the Safety Stock, which storage space shall be outside the then current Premises.

 5.7.4 Although fully treated, finished Membrane is preferable, if the parties mutually agree that
it is a necessity in order to facilitate the Move, up to 60,000 feet (fifteen percent (15%)) of the Safety Stock may be comprised of gel rolls, which are composed of Flat Sheet UPE Membrane that has not yet been processed through the Annealing
Line. Any such gel rolls shall be processed at the Premises when such rolls are actually processed. 
  

	6.	TERM AND TERMINATION 

  

	6.1.	The effective period of this Agreement (the “Term” or “Term of this Agreement”) shall begin on the Effective Date and continue thereafter until
December 31, 2012 or until earlier termination in accordance with Section 6.2. Any Release issued by a Supplied Party before the effective date of termination and in accordance with Section 5.4 hereof shall be fulfilled by the
Supplying Party. 

  

	6.2.	Either party may terminate this Agreement prior to December 31, 2012 without prejudice to any rights or liabilities accruing up to the date of termination:

  

	 	(i)	in the event of a material breach by the other party of any of the terms and conditions of this Agreement, by giving the other party written notice of such breach, provided
that such breach shall not have been cured within one hundred twenty (120) days following such notice; or, 

  

	 	(ii)	immediately, by written notice thereof, if any of the following events or an event analogous thereto occurs: 

  

	 	a.	an adjudication has been made that the other party is bankrupt or insolvent; 

  

	 	b.	the other party has filed bankruptcy proceedings or has had such proceedings filed against it, except as part of a bona fide scheme for reorganization;

	 	(iii)	at any time for convenience of the terminating party upon twenty-four (24) months prior written notice to the other party. 

  

 Page 14 of 28 

	6.3.	Termination under this Section 6 shall be in addition to and not a substitute for other rights or causes of action of the terminating party. 

  

	6.4.	Termination of this Agreement shall not in any way operate so as to impair or destroy any of the rights or remedies of either party, either at law or in equity, nor shall it
relieve the parties of their obligations pursuant to Sections 1, 3.1, 4.5, 4.6, 4.7, 6, 8, 9, and 13 through 16 hereof, each of which shall survive the termination or expiration of this Agreement. 

  

	7.	PRICES AND PAYMENTS  

  

	7.1.	Machine Hourly Rates. The hourly rates (“Machine Hourly Rates”) for use by Entegris of Millipore’s VMF4 Line, Film 1 Annealing Line and
Mix Room equipment (the “Machines”), and the invoicing thereof, shall be as set forth in this Section 7.1. Machine usage (including production and research and development usage) shall be calculated in accordance with the formula set
forth in Annex 2. 

  

	 	7.1.1.	Machine Hourly Rates. Commencing on the Effective Date, the Machine Hourly Rates set forth in Annex 1, subject to the annual adjustments as set forth below in
this Section, shall be applicable from the Effective Date through the end of the period of the Term of this Agreement. The Machine Hourly Rates shall be adjusted annually as of January 1 of each year, beginning in calendar year 2010, to reflect
(i) the then most recent August-to-following-August percentage changes, up or down, in the Producer Price Index for the industry group Pharmaceutical Preparation Manufacturing (series identification number PCU325412325412), (ii) any
demonstrated increases in Millipore’s costs associated directly with use of the Machines hereunder and which costs are extraordinary, not presently anticipated and not reflected in the Producer Price Index used pursuant to clause
(i) above, and (iii) changes to depreciation charges as a result of capital improvements to the Machines for the production of Membranes, as set forth in Section 7.4.2; provided, however, that commencing on January 1, 2009 the
Machine Hourly Rates for Millipore’s VMF4 Line will not be subject to such annual changes and will remain at $313.38 per hour for the Term of this Agreement. Machine Hourly Rates to Entegris are independent of Millipore production volumes on
the Machines.  

  

	 	7.1.2.	 Invoicing for Machine Hourly Rates. Millipore shall be entitled to invoice Entegris monthly for Machine usage following the end of each
month. The Machine Hourly Rates used for the first two months of each calendar quarter shall be the average Machine Hourly Rates that would apply for the budgeted use of each Machine for such quarter, as calculated by Millipore based on the then
most recent projections provided by Entegris pursuant to Section 5.4.2 hereof. The invoice for the third month of each calendar quarter shall be adjusted to effect a “true up” to actual Machine usage by invoicing for the net
difference between the Machine Hourly Rate applicable to the actual hourly usage of the Machine in 

  

 Page 15 of 28 

	 	 
question for the entire quarter multiplied times the actual hours of usage of such Machine for the quarter less the amounts invoiced for usage of such
Machine for the first two months of the quarter. This “true up” is so that Entegris effectively pays for all of a quarter’s hours at the Machine Hourly Rates appropriate for those total hours. 

  

	7.2.	Occupancy Rates. Commencing on the Effective Date, rates for occupancy and use of the Premises shall be as set forth in Exhibit B.

  

	7.3.	Support Rates. Commencing on the Effective Date, rates for extraordinary Millipore supervisory, operational
assistance and technical support (as described in Section 3.2 hereof) that are currently in use by the parties during 2005 shall be applicable from the Effective Date through December 31, 2008. Commencing on January 1, 2009, rates for
extraordinary Millipore supervisory, operational assistance and technical support (as described in Section 3.2 hereof) shall be as shown in Annex 1. These rates will be adjusted annually as of January 1 of each year, beginning in calendar
year 2010, to reflect (i) the then most recent August-to-following-August percentage changes, up or down, in the Producer Price Index for the industry group Pharmaceutical Preparation Manufacturing (series identification number PCU325412325412)
and (ii) any demonstrated increases in Millipore’s costs associated directly with providing such support hereunder and which costs are extraordinary, not presently anticipated and not reflected in the Producer Price Index used pursuant to
clause (i) above. 

  

	7.4.	Impact of Capital Investment on Prices. 

  

	 	7.4.1.	Entegris shall be responsible for funding required capital improvements to the Entegris Equipment for production of hydrophobic Membranes. Millipore shall be responsible for
funding required capital improvements to the Millipore Equipment for production of hydrophilic Membranes. To the extent that capital improvements are required for the Millipore Equipment used in the production of hydrophobic Membranes,
responsibility for funding that capital improvement shall be mutually agreed upon in accordance with Section I.1.7 of the Supplement. If one party funds the purchase of additional equipment for use in manufacture of UPE Membranes at the Premises,
that equipment shall be owned by the funding party. 

  

	 	7.4.2.	Changes to depreciation charges as a result of capital improvements to the Equipment for the production of Membranes will be reflected in the appropriate work center rates
and would be part of the rate adjustment process set forth in Sections 7.1.2 and 7.3. Millipore and Entegris each agree to inform the other of capital purchases that may eventually affect proposed rate/price changes hereunder no later than the time
that purchase orders for such capital purchases are placed. 

  

 Page 16 of 28 

	 	7.4.3.	Millipore shall have approval authority with respect to any Entegris proposed modifications to VMF 4 equipment for UPE Membrane processing. Millipore agrees that proposed
modifications to the VMF4 equipment for non-Entegris UPE Membrane processing that could influence the processing of UPE Membranes on the VMF 4 equipment shall be reviewed with Entegris and shall be subject to mutual agreement.

  

	 	7.4.4.	Millipore shall have approval authority for any Entegris proposed modifications to Film 1 manufacturing process for UPE Membranes. Financial impact of those modifications
would be mutually agreed upon prior to proceeding. 

  

	 	7.4.5.	In the event of a process change to either the Film 1 or VMF4 lines, Millipore shall be responsible for change control management for any impact on Millipore products.
Likewise, Entegris would be responsible for change control management for any impact on Entegris products. 

  

	7.5.	Membrane Prices. 

  

	 	7.5.1.	Intentionally Omitted. 

  

	 	7.5.2.	Commencing on the Effective Date through December 31, 2009, until adjusted pursuant to Section 7.5.3, prices for Flat Sheet UPE Membranes to Millipore produced at
the Premises, together with up to eight (8) rolls produced at the New Entegris Facility that are used to ascertain basic feasibility, shall be at Entegris’ Manufacturing fifteen percent (15%). For Flat Sheet UPE Membranes produced at the
New Entegris Facility (other than the rolls for feasibility evaluation as described and priced above), prices shall as set forth on Annex 3 for the Term of this Agreement. The parties acknowledge that all Flat Sheet UPE Membranes will be produced at
the New Entegris Facility after December 31, 2010. 

  

	 	7.5.3.	On or before November 15, 2009, Entegris shall notify Millipore as to the adjusted Manufacturing Cost to be in effect for the following calendar year for the Membranes
to be supplied by Entegris that will be produced at the Premises and shall make available an “open-book” review of such Manufacturing Cost. Membrane Prices hereunder will be adjusted as of January 1, 2010 to reflect such adjusted
Manufacturing Cost. Without limiting the factors involved in determining Manufacturing Cost, the Manufacturing Cost of UPE Membranes shall take into account the budgeted Machine Hourly Rates based on projected annual UPE Membrane manufacturing
volume. 

  

	7.6.	 Payment of Invoices. All amounts payable by either party to the other pursuant to this Agreement, except for amounts payable as Rent,
shall be payable within forty-five (45) days following the later of (i) receipt of ordered Membranes, 

  

 Page 17 of 28 

	 	 
performance of services or Machine usage, and (ii) receipt of invoice. All payments shall be made in U.S. Dollars. Any late payments shall be subject to

 Page 28 of 28Amended and Restated Supplemental Executive Retirement Plan

 Exhibit 10.2 
 AMENDED AND RESTATED 
 SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN 
 FOR KEY SALARIED EMPLOYEES OF 
 ENTEGRIS, INC. 
 INTRODUCTION 
 This document amends, restates and continues the Supplemental Executive Retirement Plan for Key Salaried Employees of Entegris, Inc., which was originally established effective April 1, 2001 by Mykrolis Corporation, a predecessor to
the Company and which was assumed by the Board on August 10, 2005. 
 The purpose of the Plan is to provide certain key salaried employees of the
Employer with the opportunity to defer a portion of their compensation on an unfunded, nonqualified basis as hereinafter provided and to provide benefits to such employees that are supplemental to the benefits provided under the Savings Plan.

 The amendment and restatement of the Plan set forth herein is intended inter alia to conform the Plan to the requirements of Section 409A,
including the transition rules and exemptive relief provisions thereunder, and shall be construed consistent with that intent. Notwithstanding the foregoing, neither the Company nor any of its officers or directors, nor any other person charged with
administrative responsibilities under the Plan, shall be liable to any employee or former employee of the Company, or to any spouse or other beneficiary of any such employee or former employee, by reason of the failure of any benefit hereunder to
comply with the requirements of Section 409A. 
 For purposes of compliance with Section 409A, the Plan consists of two parts: (i) amounts
deferred on behalf of a Participant that were earned and vested on or after January 1, 2005, including all income, gains and losses credited or charged with respect thereto (“Section 409A deferrals”) and (ii) amounts deferred on
behalf of a Participant that were earned and vested on or before December 31, 2004 (including all income, gains and losses credited or charged with respect thereto) (“grandfathered deferrals”). With respect to Section 409A
deferrals, the Plan is intended to comply with the requirements of Section 409A and shall be interpreted and administered in a manner consistent with such requirements. With respect to grandfathered deferrals, the Plan is intended to be
grandfathered for purposes of Section 409A and therefore exempt from Section 409A. 
 The terms of this amended and restated Supplemental Plan are
effective as of January 1, 2009 except as indicated otherwise herein and except with respect to grandfathered deferrals, which will continue to be governed by the terms of the Plan as in effect on December 31, 2004. There has been no
material modification of the grandfathered deferrals within the meaning of Section 409A after October 3, 2004, although the Company reserves the right to amend grandfathered deferrals in the future to the extent permitted by the terms of
the Plan as in effect on December 31, 2004. A copy of the Plan as in effect on December 31, 2004 is attached hereto as Appendix A. The rights of a Participant in the Plan who separated from service of the Employer on or prior to
December 31, 2008 shall be governed by the terms of the Plan, including operational terms, as in effect on the date of such separation from service and in accordance with the requirements of Section 409A, to the extent applicable.

 SECTION 1 DEFINITIONS

	1.10.	“Supplemental Account” means, for each Participant, the account under this Supplemental Plan to which contributions hereunder shall be credited in accordance with

 SECTION 2 SUPPLEMENTAL SAVINGS PLAN BENEFITS

any calendar year (prior to any deferrals under the Savings Plan, this Supplemental Plan, or any other nonqualified deferred compensation plan of the Company). 

  

	2.2.	Supplemental Employer Matching Contributions. The Company shall credit to the Supplemental Account of each Participant who has elected to participate in pre-tax
deferrals under the Savings Plan to the maximum extent permitted thereunder (taking into account any limitations imposed under the Savings Plan to comply with the qualification requirements of the Code) an amount equal to the excess of (a) over
(b), where (a) is the amount of employer matching contributions which would have been made to the Savings Plan in the absence of the limitations of Sections 401(a)(17), 402(g) and/or 415 of the Code, the nondiscrimination requirements of Code
Section 401(m) and any compensation deferrals under this Supplemental Plan or any other nonqualified deferred compensation plan of the Company, and (b) is the amount of employer matching contributions actually made to the Savings Plan.

  

	2.3.	Supplemental Employer Discretionary Contributions. The Company in its sole discretion may credit employer discretionary contributions to the Supplemental Account of
each Participant in an amount and on an annual or such other basis as the Company may determine. The Company may, but is not obligated to, determine the amount of such employer discretionary contributions by considering the amount of employer
discretionary contributions which would have been made to the Savings Plan on behalf of a Participant in the absence of the limitations of Sections 401(a)(17), 402(g) and/or 415 of the Code, the nondiscrimination requirements of Code
Section 401(m) and any compensation deferrals under this Supplemental Plan or any other nonqualified deferred compensation plan of the Company, minus the amount of employer discretionary contributions actually made to the Savings Plan on behalf
of such Participant. 

  

 -3- 

	2.4.	Other Employer Credits. The Company in its sole discretion may credit a discretionary amount to the Supplemental Accounts of one or some Participants, in such an
amount and at such time, and subject to such other terms and conditions as the Company may determine in its sole discretion. 

 SECTION 3 DEFERRAL ELECTION 
  

	3.1.	In General. Each deferral under Section 2.1 shall be made by the Participant’s delivery to the Administrator of a deferral election, on such form or forms as
the Administrator may determine in its discretion, on or before the date specified by the Administrator, which date shall in all events (except as provided in 3.2 below) be, or fall prior to: 

 (i) in the case of any bonus that qualifies as “performance-based compensation” within the meaning of Treas. Regs. § 1.409A-1(e), the
date that is six (6) months before the end of the performance period, but only if the Participant has been in continuous employment with the Employer since the later of the beginning of the performance period or the date the performance
criteria are established and only if, on the date of the deferral election, the compensation has not become readily ascertainable (as determined in accordance with Treas. Regs. § 1.409A-2(a)(8)). 
 (ii) in every other case, the last day of the calendar year preceding the calendar year in which are to be performed the services to which the deferred
compensation relates. 
 Each election made under this 3.1 shall become irrevocable in accordance with such rules as the Administrator may
establish but not later than the election deadline specified in (i) or (ii) above, as applicable. Notwithstanding the above, the Administrator may permit a Participant to make a deferral election without meeting the requirements of this
Section 3.1, pursuant to such procedures as the Administrator may determine in its discretion, to the extent permitted by transition guidance issued under Section 409A of the Code. 
 The Administrator may impose a minimum deferral amount for anyone electing to participate in this Supplemental Plan. 
  

	3.2.	First Year of Participation. Notwithstanding Section 3.1 above, an individual who first becomes eligible to participate in this Supplemental Plan during the
course of a calendar year may elect to defer a specified portion or percentage of his gross compensation in respect of services to be performed for the remainder of the year by delivering to the Administrator an irrevocable deferral election within
thirty (30) days of first becoming eligible. An individual who already participates or is eligible to participate in (including an individual who has any entitlement, vested or unvested, to payments under) any other nonqualified deferred
compensation plan that would be required to be aggregated with this Supplemental Plan for purposes of Treas. Regs. § 1.409A-1(c)(2) shall not be treated as eligible for the mid-year election rules of this Section 3.2 with respect to this
Supplemental Plan, even if he had never previously been eligible to participate in this Supplemental Plan. 

  

 -4- 

	3.3.	Form of Election. Each deferral election shall be made in writing on a form prescribed by the Administrator. To the extent consistent with Section 409A, the
Administrator may condition the effectiveness of any election upon the delivery by the Participant of such other form or forms as the Administrator may prescribe. 

 SECTION 4 INVESTMENT DIRECTION 
 Participants shall be permitted, pursuant to such procedures as
the Administrator may determine in its discretion, to designate what percentage of all amounts credited to the Participant’s Supplemental Account in accordance with Section 2 above will be invested in the various investment options made
available under the Savings Plan. Notwithstanding the above, the Administrator shall not be required to make the same investment options available under this Supplemental Plan as are available under the Savings Plan and may change such investment
options at any time in its sole discretion. 
 SECTION 5 DISTRIBUTIONS AND LOANS 
  

	5.1.	General. All payments of benefits to Participants and/or their designated beneficiaries under this Supplemental Plan shall be in cash in the form of a single lump sum
paid within 90 days following the Participant’s separation from the service of the Employer within the meaning of Treas. Regs. § 1.409A-1(h); provided, however, that in the case of a Participant who is a Specified Employee at the date he
or she separates from the service of the Employer, payment shall be made on the date that is six (6) months following the date of such separation. 

  

	5.2.	Distributions While Employed. No distributions may be made to a Participant under the terms of this Supplemental Plan while the Participant is an employee of the
Employer. 

  

	5.3.	Right of Offset. If, at the time of payment hereunder, the Administrative Committee determines that the Participant to whom or on whose behalf payment is being made,
for any reason, is indebted to the Company or to any affiliate or subsidiary of the Company, the Administrative Committee shall be entitled, to the extent permitted under Section 409A of the Code, to offset such indebtedness, including any
interest accruing thereon, against any payments otherwise due under the Supplemental Plan. 

  

	5.4.	Withholding. The Company shall be entitled to withhold from payments due under the Supplemental Plan any and all taxes of any nature required by any government to be
withheld from compensation paid to Participants. 

  

	5.5.	Loans. No loans to Participants shall be permitted under the Supplemental Plan. 

  

	5.6.	 Designation of Beneficiary(ies). Each Participant shall designate in writing, on such form and subject to such conditions as the Administrator shall
prescribe (including, in the Administrator’s discretion, spousal consent in the case of married Participants), a 

  

 -5- 

	 	 
beneficiary or beneficiaries to receive any amounts remaining to be paid hereunder at the Participant’s death; but if no such beneficiary designation is
in effect at the time of the Participant’s death, or if the Participant’s beneficiary(ies) do(es) not survive the Participant, the Administrator shall cause any such remaining benefits to be paid to the executor or administrator of the
Participant’s estate. 

 SECTION 6 VESTING 
 A Participant shall be vested at all times in his or her supplemental participant contributions made under Section 2.1 and in supplemental Employer matching contributions made under Section 2.2. A
Participant shall be vested in his or her supplemental Employer discretionary contributions to the same extent that the Participant is vested in his or her Employer Profit Sharing Account under the Savings Plan. 
 SECTION 7 MISCELLANEOUS 
  

	7.1.	Amendment and Termination. 

  

	 	(1)	The Board may at any time and from time to time, amend or terminate this Supplemental Plan, without the consent of any Participant or beneficiary, provided that no such amendment or
termination shall, without the consent of the affected Participant, reduce the balance of any Participant’s Supplemental Account below what it was immediately prior to the date of such termination or amendment. 

  

	 	(2)	Any amendment or termination of the Supplemental Plan shall become effective as to a Participant or beneficiary on the first day of the month following the effective date of the
amendment or termination. 

  

	 	(3)	Upon termination of the Plan, payments hereunder shall be accelerated only to the extent permitted by Section 409A. 

  

	7.2.	No Contract of Employment. The establishment of the Supplemental Plan or any modification thereof shall not give any Participant or other person the right to remain in
the service of the Company or of any subsidiary or affiliate of the Company, and all Participants and other persons shall remain subject to discharge to the same extent as if the Supplemental Plan had never been adopted. 

  

	7.3.	Source of Funds. All payments of benefits hereunder and all costs of administration of this Plan shall be paid in cash from the general funds of the Company, and no
special or separate fund shall be required to be established or other segregation of assets required to be made to assure such payments. The Plan is intended to be a “pension plan” (within the meaning of Section 3(2) of ERISA) that is
unfunded for ERISA and tax purposes and that qualifies for the exemptions described in ERISA Sections 201(2), 301(a)(3) and 401(a)(1). 

 Nothing in this Section 7.3 shall be construed as prohibiting the Company from establishing, in its discretion, a bookkeeping account or reserve to meet its obligations 

  

 -6- 

 
hereunder and/or a so-called “rabbi trust” or similar grantor trust, and the Company may fund such trust for the purpose of providing benefits
hereunder, so long as the funding of such a trust or account does not jeopardize the unfunded status of the Plan under ERISA or effective tax deferral under the Code. Except as provided in the preceding sentence, nothing contained in the Plan and no
action taken pursuant to the provisions of this Plan shall create or be construed to create a trust of any kind, or a fiduciary relationship between the Company or the Administrator and any employee or other person. To the extent that any person
acquires a right to receive payments under the Plan, such right shall be no greater than the right of any unsecured general creditor of that person’s employer or former employer. 
  

	7.4.	Tax Effects. None of the Company, the Board, the Administrative Committee, and any firm, person, or corporation, represents or guarantees that any particular federal,
state or local tax consequences will occur as a result of any Participant’s participation in this Supplemental Plan, Each Participant shall consult with his or her own advisors regarding the tax consequences of participation in this
Supplemental Plan. 

  

	7.5.	Administration of the Plan. The Administrator shall have full power to interpret and administer this Supplemental Plan and determine the eligibility of any person for
benefits hereunder and the amount of any such benefit, in its discretion. Without limiting the foregoing, the Administrator shall have full discretionary power and authority, not inconsistent with the express provisions of the Plan, to select those
individuals who may participate in the Plan; to determine their gross compensation eligible for deferral under the Plan; to determine eligibility to commence receipt of benefits (including, without limitation, any determination as to the proper
treatment of leaves of absence and other periods when an individual is not actively rendering service to the Employer); to adopt, alter, and repeal such rules, guidelines and procedures for administration of the Plan and for its own acts and
proceedings as it shall deem advisable; to prescribe the form of any election under the Plan; and otherwise to supervise the administration of the Plan. Any discretionary action by the Administrator under the Plan that affects the rights or benefits
under the Plan of an individual who is a member of the Administrator (other than an action of general applicability to all Participants) must be approved by the Board. The Administrator shall establish claims procedures under the Plan consistent
with the requirements of Section 503 of the Employee Retirement Income Security Act of 1974, as amended. 

  

	7.6.	Entire Agreement; Successors. This Supplemental Plan, including any subsequently adopted amendments, shall constitute the entire agreement or contract between the
Company and any Participant regarding the Supplemental Plan. There are no covenants, promises, agreements, conditions or understandings, either oral or written, between the Company and any Participant relating to the subject matter hereof, other
than those set forth in this Supplemental Plan. This Supplemental Plan and any amendment shall be binding on the parties hereto and their respective heirs administrators, trustees, successors and assigns, and on all designated beneficiaries of the
Participant. 

  

	7.7.	 Severability. If any provision of this Supplemental Plan shall be held or deemed to be invalid, inoperative or unenforceable as applied to any
particular case in any jurisdiction 

  

 -7- 

	 	 
or jurisdictions, because of its conflicting with any constitution or statute or rule of law or public policy or for any other reason, such circumstances
shall not have the effect of rendering the provision or provisions in question invalid, inoperative or unenforceable in any other jurisdiction or of rendering any other provision or provisions herein contained invalid, inoperative or unenforceable,
but this Supplemental Plan shall be reformed and construed in any such jurisdiction or case as if such invalid, inoperative or unenforceable provision had been contained herein and such provision reformed so that it would be valid, operative and
enforceable to the maximum extent permitted in such jurisdiction or in such case. 

 IN WITNESS WHEREOF, the Company
has caused this Amended and Restated Supplemental Plan to be executed by its duly authorized officer as of the 31st day of July, 2008.
