 HISTORY 
 PPG Industries, Inc. (referred to herein as “PPG”), on behalf of itself and as agent for certain of its Subsidiary Corporation and Affiliates, established the PPG Industries Employee Savings
Plan (“Savings Plan”) effective July 1, 1965. The purpose of the Savings Plan has been to encourage Eligible Employees to save a part of their compensation systematically and to enable them to acquire a stock interest in PPG.

 Effective December 1, 1988, the Savings Plan and its Trust was converted to an employee stock ownership plan and, on August 9,
1989, the Savings Plan received a favorable Determination Letter from the Internal Revenue Service that the Savings Plan, as amended through November 29, 1988, and as further amended March 28, 1989, met the requirements of Code
Sections 401(a), 401(k) and 4975(e)(7). 
 Effective July 1, 1988, PPG established the PPG Industries Employee Savings Plan II

determination letters establishing that Savings Plan II, as amended through November 29, 1988, met the requirements of Code Sections 401(a), 401(k) and 4975(e)(7). 
 Effective May 15, 1991, the Savings Plan and Savings Plan II were merged in accordance with Code Section 414(1), and the resulting plan was named “The PPG Industries, Inc. Employee Savings
Plan.” (Hereinafter: “Plan.”) 
 On July 8, 1995, the Internal Revenue Service issued a favorable letter of determination
establishing that the Plan as amended through April 6, 1995 continued to meet the requirements of Code Sections 401(a), 401(k) and 4975(e)(7). 
 On November 7, 2002, the Internal Revenue Service issued a favorable letter of determination establishing that the Plan as amended through February 25, 2002 continued to meet the requirements of
Code Sections 401(a), 401(k) and 4975(e)(7). 
 Effective as of January 1, 2006, the Plan was amended and restated in its entirety.

 Effective as of January 1, 2009, the Plan was amended and restated in its entirety. 

Effective January 1, 2011, the Plan is amended and restated in its entirety as set forth herein.

	3.3	PAYMENT OF MATCHING CONTRIBUTIONS AND THE RS CoGEN SAFE HARBOR CONTRIBUTION TO THE PLAN 

 

	 	(a)	The payment of Matching Contributions and the RS CoGen Safe Harbor Contribution may be made, in the discretion of the Corporation or its designee, in the form of either
cash, shares of PPG Stock, Loan Payments or some combination of the three. In the event the rate of the Matching Contributions under Section 3.1(a) for any Plan Year has not been finally determined at the time such Contributions are due and
owing under the Plan, the Corporation shall estimate such rate and make the Contributions on the basis of the estimated rate. If the estimated rate differs from the actual rate as finally determined, an appropriate adjustment will be made in the
next Contribution made under the Plan. 

 If, and to the extent, payment for any payroll period is made in the form
of PPG Stock, the number of shares to be contributed to Participants’ Accounts for the payroll period shall be determined by dividing the amount computed pursuant to the provisions of Sections 3.1 and 3.2 by the New York Stock Exchange closing
price on the day the funds are deposited into the Participants’ Accounts. 
  

	 	(b)	To the extent made in the form of shares of PPG Stock, such Company Contributions shall be paid by delivering the shares to the Fund Manager Trustee as soon as
practicable but no later than the end of the Plan Year after the determination of the number of shares to be contributed pursuant to the provisions of this paragraph (b). Such shares may be authorized but unissued shares or shares purchased by PPG
and held in its treasury. 

  

	 	(c)	To the extent Company Contributions are made in the form of cash, such shall be paid directly to the Fund Manager Trustee as soon as practicable after the amount of
cash needed is determined. 

  

	3.4	MATCHING CONTRIBUTIONS AND RS CoGEN SAFE HARBOR NON-MATCHING CONTRIBUTIONS MADE THROUGH LOAN PAYMENTS 

 

	 	(a)	At the discretion of and to the extent determined by the Corporation, Matching Contributions and/or RS CoGen Safe Harbor Non-Matching Contributions may be funded
through Acquisition Loans. 

  

	 	(b)	All proceeds of an Acquisition Loan shall be used within a reasonable time after receipt by the Trustee for one of the following purposes: 

 

	 	(1)	To acquire PPG Stock; and 

  

	 	(2)	To repay such loan; and 

  

	 	(3)	To repay a prior Acquisition Loan. 

  

	 	(c)	 All assets acquired by the Plan with the proceeds of an Acquisition Loan shall be

  
 3.5

	 	 
added to and maintained in the Suspense Account. Such assets shall be held for the exclusive benefit of Participants and their Beneficiaries in accordance with Code Section 401(a)(2).

  

	 	(d)	PPG Stock acquired by the Plan with the proceeds of an Acquisition Loan will be allocated to Participants’ Accounts upon release first from the Suspense Account
and second from the Released But Not Allocated Account as provided in paragraphs (e) and (f) below. 

  

	 	(e)	PPG Stock shall be released from the Released But Not Allocated Account and allocated to Participants’ Accounts to the extent the Corporation directs that Matching
Contributions and/or RS CoGen Safe Harbor Non-Matching Contributions are made in the form of Loan Payments. While such release may vary from month to month, the Corporation shall insure that Loan Payments are substantial and recurring during the
Plan Year and that all shares released from the Suspense Account that pass through the Released But Not Allocated Account are allocated to Participants’ Accounts prior to the end of the Plan Year. 

 

	         (f) 
	(1)	 Except as provided in paragraph (2) below, the number of shares of PPG Stock released from the Suspense Account shall equal the
number of shares encumbered by the Acquisition Loan held immediately before release multiplied by a fraction, the numerator of which is the amount of principal and interest paid and the denominator of which is the sum of the numerator plus the
principal and interest to be paid for all future Loan Payments. Dividends earned with respect to PPG Stock held in the Suspense Account and the Released But Not Allocated Account and any other Unallocated Shares, as that term is defined in
Section 12.7(b), may also be used to repay the Acquisition Loan. Any income that is not so used must be allocated as income of the Plan. 

  

	 	(2)	Pursuant to Code Section 404(k), in the event that Dividends that are otherwise allocable to Participants’ Accounts are used to repay any portion of an
Acquisition Loan, then the number of shares of PPG Stock released from the Suspense Account and to the Released But Not Allocated Account and allocated to such Participants’ Accounts shall equal the number of shares necessary to provide each
such Participant with a fair market value equal to the Dividends that would have been added to his Account but for this paragraph (2) and Section 15.14(c). 

 

	 	(g)	The value of the shares from the Suspense Account and the Released But Not Allocated Account when allocated to Participants’ Accounts, including the shares
allocated to replace Dividends used to repay a portion of an Acquisition Loan, in accordance with paragraph (f)(2) above, shall be determined by using the closing price of PPG Stock as reported in the Wall Street Journal for the day in which
such shares are credited with the procedure set forth in Section 3.3(b). 

  

	 	(h)	PPG Stock acquired by the Plan with the proceeds of an Acquisition Loan is and remains at all times subject to the provisions of Section 15.12.

 3.8

 SECTION 4 
 INVESTMENT OF EMPLOYEE SAVINGS, ELECTIVE DEFERRALS, 
 CATCH-UP
CONTRIBUTIONS AND ROLLOVERS 
  

	4.1	INVESTMENT ELECTIONS 

  

	 	(a)	Employee Savings deducted or Elective Deferrals and Catch-Up Contributions withheld from a Participant’s Eligible Earnings shall be invested at the election of the
Participant. Such election must specify the percentage (in whole percentages only) to be invested in each Fund. 

  

	 	(b)	Prior to January 1, 2007, the Participant’s election with respect to Savings, if any, may be different than such Participant’s election with respect to
Elective Deferrals and Catch-Up Contributions. On or after January 1, 2007, Participants shall make a single investment election that will apply to Savings, Elective Deferrals and Catch-Up Contributions, if applicable. 

 

	 	(c)	A Participant may change his investment election for amounts not already in the Participant’s Account each payroll period by contacting the SPSC in accordance with
the procedures established by the Administrator. 

  

	 	(d)	Matching Contributions made to each Participant’s Account will be invested in accordance with that Participant’s investment election on file.

  

	4.2	REALLOCATIONS AND TRANSFERS 

  

	 	(a)	Notwithstanding the provisions of Section 4.1, a Participant may elect on any business day in which the New York Stock Exchange is open, in accordance with
procedures established by the Administrator, to reallocate or transfer all or any part of his Savings (increased by any Gain or reduced by any Loss thereon) or Elective Deferrals, Catch-Up Contributions and Matching Contributions (increased by any
Gain or reduced by any Loss thereon) from one Fund to any other Fund or Funds. The Participant must elect either the percentage or dollar amount of each Fund that is to be transferred out of such Fund or the percentage of the total reallocated
amount to be transferred into each Fund. The percentage being reallocated shall apply to the entire Fund. 

  

	 	(b)	 Reallocations or transfers shall be based on the amount of Savings, Elective Deferrals, Catch-Up Contributions and Matching Contributions invested in
the Fund from which the reallocation or transfer is made on the date the transactions are processed in accordance with rules and procedures established by the Administrator pursuant to Section 15.2. Reallocations or transfers that require the
sale of PPG Stock will be based on the Current Market Value of the PPG Stock Fund on the date the transactions are processed in accordance with rules and procedures established by the Administrator pursuant to Section 15.2. Except as
hereinafter provided, such rules and procedures shall provide that elections to 

  
 4.1

	 	 
reallocate or transfer that are received prior to market close (a “Confirmed Election”) will be processed on the date of the election. In the event that the funds available from all
sources (such sources shall include but are not limited to existing cash, new contributions and dedicated lines of credit) are not sufficient to process all Confirmed Elections, then the available funds shall be applied until exhausted to process
the Confirmed Elections in the order in which received. Those Confirmed Elections that cannot be processed as of the market close on the date of election in accordance with the normal “first in, first out” process shall not be processed
but shall be treated as Confirmed Elections first received as of the next day on which funds are available to process transfers or reallocations and normal processing on a first in, first out basis can resume. 

 

	 	(c)	A Participant may elect to have amounts invested pursuant to this Section 4 transferred from one or more Funds to one or more other Funds in accordance with an
automatic quarterly rebalancing procedure established by the Administrator. 

  

	4.3	DIVERSIFICATION OF COMPANY STOCK 

  

	 	(a)	To the extent not otherwise provided by the Plan, each Applicable Individual shall be entitled to direct the Plan to divest any PPG Stock in which his Elective
Deferrals are invested and to reinvest an equivalent amount in other Investment Options. 

  

	 	(b)	To the extent not otherwise provided by the Plan, each Applicable Individual who is (1) a Participant who has completed at least three years of service,
(2) an alternate payee who has an Account under the Plan with respect to such a Participant or (3) a Beneficiary of a deceased Participant, shall be entitled to direct the Plan to divest any PPG Stock in which his Company Contributions are
invested and to reinvest an equivalent amount in other Investment Options. 

  

	 	(c)	 Notwithstanding any other provision of the Plan, the Plan shall not impose restrictions or conditions with respect to the investment of PPG Stock that
are not imposed on the investment of other assets of the Plan. A restriction or condition with respect to the investment of PPG Stock is a restriction on an individual’s right to divest an investment in PPG Stock that is not imposed on an
investment that is not PPG Stock or a benefit that is conditioned on investment in PPG Stock. This Section 4.3(c) shall not apply to any restriction or condition that is either required to ensure compliance with applicable securities laws or is
reasonably designed to ensure compliance with applicable securities laws. Notwithstanding the foregoing, the Plan may (1) limit the extent to which an individual’s Account balance can be invested in PPG Stock, provided the limitation
applies without regard to a prior exercise of rights to divest PPG Stock, (2) impose reasonable restrictions on the timing and number of investment elections that an individual can make to invest in PPG Stock, provided that the restrictions are
designed to limit short-term trading in PPG Stock, (3) impose fees on other Investment Options that are not imposed on the investment in PPG Stock, (4) impose a 

  
 4.2

	 	 
reasonable fee for the divestment of PPG Stock, (5) allow transfers to made into or out of a stable value or similar fund more frequently than a PPG Stock fund, (6) provide for
transfers out of a qualified default investment alternative within the meaning of Department of Labor Regulation Section 2550.404c-5(e) more frequently than a fund invested in PPG Stock and (7) prohibit any further investment in PPG Stock
(other than dividends paid on PPG Stock under the Plan, which are reinvested in PPG Stock). 

  

	 	(d)	The Plan shall not be treated as failing to meet the requirements of this Section 4.3 merely because the Plan limits the time for divestment and reinvestment to
periodic, reasonable opportunities occurring no less frequently than quarterly. 

  

	 	(e)	This Section 4.3 is intended to comply with the requirements of Code Section 401(a)(35) and Treasury Regulation Section 1.401(a)(35)-1 and shall be
interpreted and applied in accordance therewith. 

  

	4.4	ROLLOVERS 

 Participants
may elect to roll over distributions from tax-qualified plans into the Plan in accordance with the following: 
  

	 	(a)	All Rollovers must be made in accordance with rules established by the Administrator. Participants who have had a Termination of Employment and who have not been
rehired shall not be able to Rollover as provided in this Section 4.4. 

  

	 	(b)	The Plan shall not accept: 

  

	 	(1)	Rollovers of property other than cash, except as provided in paragraph (e) below; or 

 

	 	(2)	After-tax rollover contributions; or 

  

	 	(3)	Trustee-to-trustee transfers from any tax-qualified plan. 

  

	 	(c)	Rollovers shall be invested in the before-tax portion of the Plan and shall be invested in such whole number percentages and in such Fund(s) as elected by the
Participant. 

  

	 	(d)	Notwithstanding the foregoing or any other provision of the Plan to the contrary, effective as of January 1, 2002, in accordance with rules established by the
Administrator, any Participant may make written application to the Administrator to allow a transfer in cash to this Plan of an amount that constitutes a Rollover Contribution (as defined under this paragraph (d) below). Upon receipt of the
completed Rollover contribution application, the Administrator or its delegate, in its sole discretion, shall determine whether or not such Rollover contribution will be accepted hereunder and promptly shall notify the Participant of its
determination. 

  
 4.3

 A “Rollover Contribution” means that amount that is transferred to the Plan by a
Participant, which represents all or part of a distribution received by the Participant from an eligible retirement plan, as defined in Code Section 402(c)(8)(B), which distribution meets the requirements of Code Section 402(c)(4) and has
been paid to the Plan by delivery of such amount, in a form acceptable to the Administrator or its delegate, within the time established by Code Section 402(c)(3); except, however, that any portion that consists of after-tax contributions shall
not be a Rollover Contribution and, therefore, may not be rolled over into this Plan. 
  

	 	(e)	A Participant may elect to rollover an account from another tax-qualified plan that includes an outstanding loan balance in accordance with procedures established by
the Administrator and the following: 

  

	 	(1)	No more than two outstanding loans may be rolled over; and 

  

	 	(2)	The Participant must execute all of the forms required by the Administrator; and 

 

	 	(3)	Following the rollover, the loan becomes subject to all applicable provisions of this Section 4; and 

 

	 	(4)	The Participant pays any amounts necessary to cause the loan payments to be current.

	5.2	DIVERSIFICATION RIGHTS 

  

	 	(a)	For Plan Years prior to January 1, 2007, notwithstanding the provisions of Section 5.1, a Participant who will attain age 55 or older or who has a Termination
of Employment during the Plan Year may elect to reallocate or transfer all or any percentage of the Company Contributions attributable to his Account (increased by any Gain or reduced by any Loss thereon) from the PPG Stock Fund to any other Fund or
Funds in accordance with Section 4.2. 

 Notwithstanding the provisions of Sections 5.1 and 5.2, a Participant
who will attain the age of 50 or older or who has a Termination of Employment during the Plan Year may elect to reallocate or transfer up to 50% of the Company Contributions attributable to his Account (increased by any Gain or reduced by any Loss

exceed $5,000, such balance shall be distributed no later than 90 days following such Participant’s Termination of Employment. 

  

	 	(2)	No involuntary cashout, as described in paragraph (1) above shall be made after the “annuity starting date,” as defined in Code Section 417(e)(1).

  

	 	(3)	All Participants with an Account balance at December 31, 1997 are not affected by the above paragraphs. Affected Participants are those hired on or after
January 1, 1998. 

  

	 	(4)	In the event of a distribution pursuant to this Section 10.3(b) in an amount greater than $1,000, if the Participant does not elect to have such distribution paid
directly to an eligible retirement plan (as that term is defined in Code Section 401(a)(31)(B)(ii)) specified by the Participant in a direct rollover or to receive the distribution directly, then such Participant’s distribution shall be
directly rolled over to an individual retirement account in accordance with the requirements of Code Section 401(a)(31)(B). 

  

	 	(5)	In the event of a distribution pursuant to this Section 10.3(b) in an amount of $1,000 or less, the mandatory distribution shall be paid out in cash.

  

	10.4	WITHDRAWALS FOLLOWING DEFERRAL 

 Subject to Sections 10.3(b), 10.8 and 14.3, a Participant who elects to defer receipt of part or all of his vested Account balance: 

 

	 	(a)	May request withdrawals at any time and from time to time by contacting the SPSC; or 

  
 10.2

	 	(b)	May elect to have automatic recurring monthly withdrawals in an amount specified by the Participant. Such automatic withdrawals shall be taken from Funds in which the
Participant’s Account is invested ratably on the basis of the portion of the Participant’s Account invested in each such Fund. All such automatic withdrawals from the PPG Stock Fund shall be paid in cash. 

 

	 	(c)	All such withdrawals shall be made in accordance with procedures established by the Administrator. 

 

	10.5	CONSENT TO DISTRIBUTION 

Unless the Participant elects otherwise, pursuant to the provisions of the Plan, payment of benefits shall begin no later than the 60th
day after the close of the Plan Year in which: 
  

	 	(a)	The Participant attains age 65; or 

  

	 	(b)	The Participant’s Termination of Employment occurs. 

 Notwithstanding the foregoing, the failure of a Participant to consent to a distribution shall be deemed as an election to defer commencement of benefits otherwise payable under this Section 10.5.

  

	10.6	DISTRIBUTION TO BENEFICIARY 

 Notwithstanding any other provision of this Section 10, if the Participant dies before his entire interest has been distributed to him, the remaining portion of such interest will be paid to his
Beneficiary in accordance with Section 13. 
  

	10.7	EFFECTIVE DATE OF WITHDRAWAL 

 The effective date of any withdrawal made pursuant to this Section 10 shall be determined in accordance with the procedures established by the Administrator. 

 

	10.8	MINIMUM REQUIRED DISTRIBUTIONS 

  

	 	(a)	For purposes of this Section 10.8, the following definitions apply: 

 DESIGNATED BENEFICIARY means the individual who is designated as the beneficiary under the Plan and is the designated beneficiary under Code Section 401(a)(9) and Treasury Regulation
Section 1.401(a)(9)-4, Q&A-1. 
 DISTRIBUTION CALENDAR YEAR means a calendar year for which a minimum
distribution is required. For distributions beginning before the Participant’s death, the first Distribution Calendar Year is the calendar year immediately preceding the calendar year that contains the Participant’s Required Beginning
Date. For distributions beginning after the Participant’s death, the first Distribution Calendar Year is the calendar year in which distributions are required to begin pursuant to Section 10.8(c)(2). 

  
 10.3

 LIFE EXPECTANCY means life expectancy as computed by use of the Single Life Table in
Treasury Regulation Section 1.401(a)(9)-9. 
 REQUIRED BEGINNING DATE means 

 

	 	(1)	 December 1 or later (but not later than the following April 1), as determined by the Administrator, of the Plan Year that is the later of the
year in which the Participant attains age 70 1/2 or
the Plan Year in which the Participant has a Termination of Employment; or 

  

	 	(2)	 Notwithstanding any of the above provisions, in the case of a Participant who is a 5% owner, no later than the April 1 of the Plan Year following
the Plan Year such Participant attains age 70 1/2.

  

	         (b) 
	(1)	 The provisions of this Section 10.8 shall apply for purposes of determining required minimum distributions for Distribution
Calendar Years beginning with the 2005 calendar year, as well as required minimum distributions for the 2004 Distribution Calendar Year that are made on or after April 17, 2004. 

 

	 	(2)	Required minimum distributions for 2004 under this Section 10.8 will be determined as follows. If the total amount of 2004 required minimum distributions under the
Plan made to the distributee prior to the effective date of this Section 10.8 equals or exceeds the required minimum distributions determined under this Section 10.8, then no additional distributions will be required to be made for 2004 on
or after such date to the distributee. If the total amount of 2004 required minimum distributions under the Plan made to the distributee prior to the effective date of this Section 10.8 is less than the amount determined under this
Section 10.8, then required minimum distributions for 2004 on and after such date will be determined so that the total amount of required minimum distributions for 2004 made to the distributee shall be the amount determined under this
Section 10.8. 

  

	 	(3)	The requirements of this Section 10.8 shall take precedence over any inconsistent provisions of the Plan. 

 

	 	(4)	All distributions required under this Section 10.8 shall be determined and made in accordance with the regulations under Code Section 401(a)(9).

  

	 	(5)	Notwithstanding the other provisions of this Section 10.8, other than Section 10.8(c)(4), distributions may be made under a designation made before
January 1, 1984, in accordance with Section 242(b)(2) of the Tax Equity and Fiscal Responsibility Act (TEFRA) and the provisions of the Plan that relate to TEFRA Section 242(b)(2). 

  
 10.4

	         (c) 
	(1)	 The Participant’s entire interest shall be distributed, or begin to be distributed, to the Participant no later than the
Participant’s Required Beginning Date. 

  

	 	(2)	If the Participant dies before distributions begin, the Participant’s entire interest shall be distributed, or begin to be distributed, no later than as follows:

  

	 	(A)	 If the Participant’s surviving Spouse is the Participant’s sole Designated Beneficiary, then distributions to the surviving Spouse shall
begin by December 31 of the calendar year immediately following the calendar year in which the Participant died or by December 31 of the calendar year in which the Participant would have attained age 70 1/2, if later. 

 

	 	(B)	If the Participant’s surviving Spouse is not the Participant’s sole Designated Beneficiary, then distributions to the Designated Beneficiary shall begin by
December 31 of the calendar year immediately following the calendar year in which the Participant died. 

  

	 	(C)	If there is no Designated Beneficiary as of September 30 of the year following the year of the Participant’s death, the Participant’s entire interest
shall be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. 

  

	 	(D)	If the Participant’s surviving Spouse is the Participant’s sole Designated Beneficiary and the surviving Spouse dies after the Participant but before
distributions to the surviving Spouse begin, this Section 10.8(c), other than Section 10.8(c)(1), shall apply as if the surviving Spouse were the Participant. 

For purposes of this Section 10.8(c)(2) and Section 10.8(g), distributions are considered to begin on the Participant’s
Required Beginning Date (or, if Section 10.8(c)(2)(D) applies, the date distributions are required to begin to the surviving Spouse under Section 10.8(c)(2)(A)). If annuity payments irrevocably commence to the Participant before the
Participant’s Required Beginning Date (or to the Participant’s surviving Spouse before the date distributions are required to begin to the surviving Spouse under Section 10.8(c)(2)(A)), the date distributions are considered to begin
is the date distributions actually commence. 
  

	 	(d)	 Unless the Participant’s interest is distributed in the form of an annuity purchased from an insurance company or in a single sum on or before the
Required Beginning Date, as of the first Distribution Calendar Year distributions will be made in accordance with Sections 10.8(e), 10.8(f) and 10.8(g). If the Participant’s interest is distributed in the form of an annuity purchased from an

  
 10.5

	 	 
insurance company, distributions thereunder will be made in accordance with the requirements of Code Section 401(a)(9) and the regulations thereunder. Any part of the Participant’s
interest that is in the form of an individual account described in Code Section 414(k) will be distributed in a manner satisfying the requirements of Code Section 401(a)(9) and the regulations that apply to individual accounts.

  

	         (e) 
	(1)	 If the Participant’s interest is paid in the form of annuity distributions under the Plan, payments under the annuity will satisfy
the following requirements: 

  

	 	(A)	The annuity distributions will be paid in periodic payments made at intervals not longer than one year; and 

 

	 	(B)	The distribution period will be over a life (or lives) or over a period certain not longer than the period described in Section 10.8(f) or 10.8(g); and

  

	 	(C)	Once payments have begun over a period certain, the period certain will not be changed even if the period certain is shorter than the maximum permitted; and

  

	 	(D)	Payments will either be nonincreasing or increase only as follows: 

  

	 	(i)	By an annual percentage increase that does not exceed the annual percentage increase in a cost-of-living index that is based on prices of all items and issued by the
Bureau of Labor Statistics; or 

  

	 	(ii)	To the extent of the reduction in the amount of the Participant’s payments to provide for a survivor benefit upon death, but only if the Designated Beneficiary
whose life was being used to determine the distribution period described in Section 10.8(f) dies or is no longer the Participant’s Designated Beneficiary pursuant to a qualified domestic relations order within the meaning of Code
Section 414(p); or 

  

	 	(iii)	To provide cash refunds of employee contributions upon the Participant’s death; or 

 

	 	(iv)	To pay increased benefits that result from a Plan amendment. 

  

	 	(2)	 The amount that must be distributed on or before the Participant’s Required Beginning Date (or, if the Participant dies before distributions
begin, the date distributions are required to begin under Section 10.8(c)(2)(A) or (B)) is the payment that is required for one payment interval. The second payment need not be made until the end of

  
 10.6

	 	 
the next payment interval even if that payment interval ends in the next calendar year. Payment intervals are the periods for which payments are received, e.g., bi-monthly, monthly, semi-annually
or annually. All of the Participant’s benefit accruals as of the last day of the first Distribution Calendar Year will be included in the calculation of the amount of the annuity payments for payment intervals ending on or after the
Participant’s Required Beginning Date. 

  

	 	(3)	Any additional benefits accruing to the Participant in a calendar year after the first Distribution Calendar Year will be distributed beginning with the first payment
interval ending in the calendar year immediately following the calendar year in which such amount accrues. 

  

	                 (f) 
	(1)	 If the Participant’s interest is being distributed in the form of a joint and survivor annuity for the joint lives of the
Participant and a non-Spouse Designated Beneficiary, annuity payments to be made on or after the Participant’s Required Beginning Date to the Designated Beneficiary after the Participant’s death must not at any time exceed the applicable
percentage of the annuity payment for such period that would have been payable to the Participant using the table set forth in Treasury Regulation Section 1.401(a)(9)-6, Q&A-2. If the form of distribution combines a joint and survivor
annuity for the joint lives of the Participant and a non-Spouse Designated Beneficiary and a period certain annuity, the requirement in the preceding sentence will apply to annuity payments to be made to the Designated Beneficiary after the
expiration of the period certain. 

  

	 	(2)	Unless the Participant’s Spouse is the sole Designated Beneficiary and the form of distribution is a period certain and no life annuity, the period certain for an
annuity distribution commencing during the Participant’s lifetime may not exceed the applicable distribution period for the Participant under the Uniform Lifetime Table set forth in Treasury Regulation Section 1.401(a)(9)-9 for the
calendar year that contains the annuity starting date. If the annuity starting date precedes the year in which the Participant reaches age 70, the applicable distribution period for the Participant is the distribution period for age 70 under the
Uniform Lifetime Table set forth in Treasury Regulation Section 1.401(a)(9)-9 plus the excess of 70 over the age of the Participant as of the Participant’s birthday in the year that contains the annuity starting date. If the
Participant’s Spouse is the Participant’s sole Designated Beneficiary and the form of distribution is a period certain and no life annuity, the period certain may not exceed the longer of the Participant’s applicable distribution
period, as determined under this Section 10.8(f)(2), or the joint life and last survivor expectancy of the Participant and the Participant’s Spouse as determined under the Joint and Last Survivor Table set forth in Treasury Regulation
Section 1.401(a)(9)-9, using the Participant’s and Spouse’s attained ages as of the Participant’s and Spouse’s birthdays in the calendar year that contains the annuity starting date. 

  
 10.7

	         (g) 
	(1)	 If the Participant dies before the date distribution of his interest begins and there is a Designated Beneficiary, the
Participant’s entire interest will be distributed, beginning no later than the time described in Section 10.8(c)(2)(A) or (B), over the life of the Designated Beneficiary or over a period certain not exceeding:

  

	 	(A)	Unless the annuity starting date is before the first Distribution Calendar Year, the Life Expectancy of the Designated Beneficiary determined using the Designated
Beneficiary’s age as of the Designated Beneficiary’s birthday in the calendar year immediately following the calendar year of the Participant’s death; or 

 

	 	(B)	If the annuity starting date is before the first Distribution Calendar Year, the Life Expectancy of the Designated Beneficiary determined using the Designated
Beneficiary’s age as of the Designated Beneficiary’s birthday in the calendar year that contains the annuity starting date. 

  

	 	(2)	If the Participant dies before the date distributions begin and there is no Designated Beneficiary as of September 30 of the year following the year of the
Participant’s death, distribution of the Participant’s entire interest will be completed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. 

 

	 	(3)	If the Participant dies before the date distribution of his interest begins, the Participant’s surviving Spouse is the Participant’s sole Designated
Beneficiary, and the surviving Spouse dies before distributions to the surviving Spouse begin, this Section 10.8(g) will apply as if the surviving Spouse were the Participant, except that the time by which distributions must begin will be
determined without regard to Section 10.8(c)(2)(A). 

  

	 	(h)	Effective for Plan Years beginning after December 31, 2008: 

  

	 	(1)	Notwithstanding any other provision of the Plan, the amount otherwise required to be distributed to a Participant or Beneficiary pursuant to this Section 10.8 for
the 2009 Distribution Calendar Year is not required to be distributed. 

  

	 	(2)	Notwithstanding any other provision of the Plan, distribution to the Beneficiary of a Participant who dies before required minimum distributions under Code
Section 401(a)(9) have commenced and whose Beneficiaries do not receive distributions commencing within one year of the Participant’s death in accordance with Code Section 401(a)(9)(B)(iii) shall be made within five years after the
date of such Participant’s death, provided that such five-year period shall be determined without regard to calendar year 2009. 

  
 10.8

	 	(3)	If all or any portion of a distribution during 2009 is treated as an Eligible Rollover Distribution but would not be so treated if the minimum distribution requirements
of this Section 10.8 had applied during 2009, such distribution shall not be treated as an Eligible Rollover Distribution. 

  

	10.9	DISTRIBUTIONS UPON PLAN TERMINATION 

 The Accounts of all Participants and Beneficiaries shall be distributed as soon as administratively feasible after the termination of the Plan, subject to the restrictions of Code Section 401(k)(10)
and the regulations thereunder. 

  
 10.9

	11.4	TIME OF PAYMENT 

 In the
event of a withdrawal of cash or whole shares of PPG Stock allocated to a Participant’s Account, such cash or shares shall be delivered or paid by the Fund Manager Trustee as soon as practicable after the effective date of the withdrawal.

  

	11.5	DIRECT ROLLOVER OF ELIGIBLE ROLLOVER DISTRIBUTIONS 

 Notwithstanding any provision of the Plan to the contrary that would otherwise limit a Distributee’s election under this Section 11.5, a distributee may elect, at the time and in the manner
prescribed by the Administrator, to have any portion of an Eligible Rollover Distribution paid directly to an Eligible Retirement Plan specified by the Distributee in a Direct Rollover.

	12.1	GENERAL 

 The Fund Manager
Trustee shall invest Participants’ Savings, Elective Deferrals and/or Catch-Up Contributions, hold or invest, as the case may be, Company Contributions and invest Earnings on each. Except to the extent Dividends are distributed according to

securities acquired in the manner prescribed by the Plan and any uninvested cash shall be held by and for the Fund Manager Trustee. The Fund Manager Trustee may, in its sole discretion, maintain in cash or cash equivalents, including commercial

houses, may be charged against the Accounts of the Participant or Beneficiary with respect to which the Participant or Beneficiary directs the investment of assets. 
  

	12.2	FUNDS 

 The Trust shall be
maintained in various Funds designated from time to time as available for Participants’ investment by the Benefits Investment Committee, which such Funds shall include a fund that invests primarily in PPG Stock (the “PPG Stock Fund”).
The Benefits Investment Committee shall select the Funds offered to Participants and may change the number or composition of the Funds without amending this Plan or any schedules thereto. 

 

	12.3	FUND ELECTIONS 

 Each
Participant shall direct the investment of all of his Accounts using such uniform procedures and mechanisms as prescribed by the Employee Benefits Committee or the Administrator from time to time. 

A Participant shall make his investment election in any combination of one or any number of the Funds offered in accordance with the
procedures established by the Employee Benefits Committee or the Administrator. 
 The Employee Benefits Committee may set a

	12.4	STOCK RIGHTS, STOCK SPLITS AND STOCK DIVIDENDS 

 A Participant shall have no right of request, direction or demand upon the Fund Manager 

  
 12.1

 
Trustee to exercise rights on his behalf to purchase shares of PPG Stock. Subject to the provisions of the Trust Agreement referred to in Section 15.1, the Fund Manager Trustee may, in its
sole discretion, exercise or sell any rights to purchase shares of PPG Stock pertaining to shares held by it. 
  

	12.5	RESPONSIBILITY FOR INVESTMENT CHOICE 

 Each Participant shall be solely responsible for the selection of his Fund choices. No fiduciary with respect to the Plan is empowered to advise a Participant as to the manner in which his Accounts are to
be invested, and the fact that a Fund is offered shall not be construed to be a recommendation for investment. 
  

	12.6	TIMING 

 Subject to
Section 2.1(b), a Participant shall make his initial investment election upon becoming a Participant and may change his investment election at any time in accordance with the procedures established by the Administrator. 

 

	12.7	VOTING OF PPG STOCK HELD BY THE TRUSTEE 

  

	 	(a)	PPG Stock held by the Trust by the Fund Manager Trustee shall be voted as follows: 

For PPG Stock allocated to Participants’ Accounts (the “Allocated Shares”), at the direction of the Administrator, the Fund
Manager Trustee shall either: 
  

	 	(1)	Appoint each Participant as the Fund Manager Trustee’s proxy to vote such Participant’s Allocated Shares; or 

 

	 	(2)	Solicit directions from each Participant as to the voting of such Participant’s Allocated Shares and vote such shares as directed by the Participant.

  

	 	(b)	PPG Stock held in the ESOP Trust by the ESOP Trustee shall be voted as follows: 

 All PPG Stock held in the ESOP Trust by the ESOP Trustee (including, without limitation, any shares held in the Released But Not Allocated Account and any other shares not allocated to Participants’
Accounts (the “Unallocated Shares”)) shall be voted by the ESOP Trustee either: 
  

	 	(1)	In the same manner as Participants vote the majority of the Allocated Shares that are voted; or 

 

	 	(2)	In the same manner in which Participants direct the Trustee to vote the majority of the Allocated Shares as to which they give directions, 

whichever is applicable. 

  
 12.2

	 	(c)	Any other rights or powers (i.e., other than voting rights) pertaining to PPG Stock held in the Trust(s) by the Fund Manager Trustee or ESOP Trustee (including, without
limitation, the right or power to tender shares pursuant to any tender offer) shall be exercised by the Trustee(s) as follows: 

  

	 	(1)	As to Allocated Shares, the Fund Manager Trustee shall solicit directions from each Participant as to the exercise of any such rights or powers pertaining to the
Participant’s Allocated Shares and shall exercise such rights or powers with respect to such shares as directed by the Participant. The Fund Manager Trustee shall not exercise any such rights or powers pertaining to any Participant’s
Allocated Shares (and, without limitation, shall not tender any Participant’s Allocated Shares) unless directed to do so by the Participant. 

  

	 	(2)	As to Unallocated Shares and Released But Not Allocated Shares, the ESOP Trustee shall exercise all such rights or powers pertaining to Unallocated Shares and Released
But Not Allocated Shares in the manner in which Participants direct the ESOP Trustee to exercise such rights or powers pertaining to the majority of the Allocated Shares as to which they give directions. In this respect, the failure of a Participant
to affirmatively direct the Fund Manager Trustee to exercise such a right or power pertaining to the Participant’s Allocated Shares and Released but Not Allocated Shares shall be considered a direction not to exercise such right or power
(including, without limitation, the right or power to tender shares pursuant to any tender offer). 

  

	 	(d)	The Fund Manager Trustee, in its discretion, may exercise its voting rights and any other rights or powers with respect to any other shares of stock held in the Fund
Manager Trust by the Fund Manager Trustee. 

  

	 	(e)	The ESOP Trustee, in its discretion, may exercise its voting rights and any other rights or powers with respect to any other shares of stock held in the ESOP Trust by
the ESOP Trustee. 

  

	12.8	TENDER OFFERS 

 As soon as
practicable after the commencement of a tender offer or exchange offer (“Offer”) for shares of PPG Stock, the Administrator shall use his reasonable best efforts to cause each Participant whose Account has allocated to it any shares of PPG
Stock to be advised in writing of the terms of the Offer, together with forms by which the Participant may instruct the Fund Manager Trustee, or revoke such instruction to tender shares of PPG Stock allocated to his Account, to the extent permitted
under the terms of any such Offer. In advising Participants of their terms of the Offer, the Administrator may include statements from the management of the Corporation setting forth its position with respect to the Offer. The number of shares of
PPG Stock with respect to which a Participant may provide instructions shall be the total number equivalent shares of PPG Stock allocated to the Participant’s Account as of the last day of the month preceding the month during

  
 12.3

 
which the Offer commenced or such other date that may be designated by the Administrator as he deems appropriate for reasons of administrative convenience. The giving of instructions to the Fund
Manager Trustee to tender shares and the tender thereof shall not be deemed a withdrawal or suspension from the Plan or a forfeiture of any portion of the Participant’s interest in the Plan. Any securities received by the Fund Manager Trustee
as a result of a tender of shares of PPG Stock allocated to Participants’ Accounts hereunder shall be held, and any cash so received shall be invested in short-terms investments for the Account of each Participant with respect to whom shares of
PPG Stock were tendered pending any reinvestment by the Fund Manager Trustee consistent with the purposes of the Plan. 
  

	12.9	EXTENT OF PARTICIPANTS’ RIGHTS 

  

	 	(a)	At the time of withdrawal by a Participant, he shall be entitled to receive PPG Stock or cash as stated in Section 11. 

 

	 	(b)	There is no provision that the Current Market Value of any security or other investment will be equal to the purchase price of such security or other investment or that
the total mount withdrawable in cash with respect to any Twenty-Four Month Hold Class or the Accumulated Mature Months Class will be equal to or greater than the amount of the Participant’s Savings and/or Elective Deferrals for such Twenty-Four
Month Hold Class or the Accumulated Mature Months Class. Each Participant assumes all risks in connection with any decrease in the market price of any PPG Stock in the PPG Stock Fund or of any investment in any Fund allocated to his Account in
accordance with the provisions of the Plan. 

  

	12.10	INVESTMENT POLICY 

 A
Savings Plan investment policy sets forth the types of investment funds that may be made available to Participants. The policy sets forth a funds “benchmark” and the actions that may be taken if a fund does not perform to its benchmark
over an extended period of time. 
  

	12.11	ERISA SECTION 404(c) 

 The
Plan intends to be in compliance with ERISA Section 404(c). 
  

	12.12	DEEMED INVESTMENT ELECTION

specified from time to time by the Benefits Investment Committee subject to the Participant’s right to redirect the investment of such amounts in accordance with the foregoing provisions of this Section 12. 

  
 12.4

 SECTION 13 
 DESIGNATION OF BENEFICIARIES IN THE EVENT OF DEATH 
  

	13.1	SURVIVING SPOUSE 

  

	 	(a)	In the case of a Participant who is legally married at the time of his death, his Beneficiary shall be his surviving Spouse. 

 

	 	(b)	A married Participant may designate a person(s) other than his Spouse, pursuant to Section 13.2, with the written consent of his Spouse on a form provided by the

Participant’s Spouse, which provides either: 

  

	 	(1)	The Spouse’s consent to the particular Beneficiary designation. Such consent shall be irrevocable unless or until the Participant elects to change such
designation. Any such change, other than the Participant’s designation of his Spouse as sole Beneficiary, requires spousal consent to such change in accordance with this paragraph (1) or in accordance with paragraph (2) below; or

  

	 	(2)	The Spouse’s general consent to the effect that the Participant may designate a Beneficiary without obtaining his Spouse’s consent to the particular
Beneficiary designation. Such consent must acknowledge that the Spouse is aware of his right to give a more limited consent. Such consent shall be irrevocable. 

 Spousal consent forms, whether pursuant to paragraph (c)(1) or (c)(2) must be witnessed by a Plan representative or by a notary public and filed with the Administrator, in this case the SPSC. 

 

	13.2	OTHER BENEFICIARY 

  

	 	(a)	In the case of a Participant who is not legally married at the time of his death, or a married Participant described in either Section 13.1(b) or (c), his
Beneficiary shall be the person(s) named by him on the latest written designation filed with the Administrator. Such designation shall become effective on the day it is delivered to the Administrator provided the Participant is alive on such day.

Subject to the provisions of this Section 13, the designation of a Beneficiary may be changed or revoked. 

 

	13.4	PAYMENT 

 Upon the death
of a Participant, the total vested amount remaining in his Account shall, at such time as may be elected by the Beneficiary, subject to the requirements of Code Section 401(a)(9) and the regulations thereunder, be paid to such
Participant’s Beneficiary in cash or in shares of PPG Stock to the extent elected by the Beneficiary and to the extent monies in the PPG Stock Fund have been invested in PPG Stock on the effective date of the distribution.

 SECTION 14 
 NONASSIGNABILITY 
  

	14.1	PROHIBITION OF ALIENATION 

Except as provided in Section 14.2, no person shall have any power to encumber, sell, alienate or otherwise dispose of his interest
under the Plan prior to actual payment to and receipt thereof by such person; nor shall the Administrator recognize any assignment in derogation of the foregoing. No interest hereunder of any person shall be subject to attachment, execution,
garnishment or any other legal, equitable, or other process, except as otherwise required by law. 
  

	14.2	QUALIFIED DOMESTIC RELATIONS ORDERS 

  

	 	(a)	Section 14.1 shall not apply to the extent that a Participant’s interest under the Plan is alienated pursuant to a “Qualified Domestic Relations
Order” (“QDRO”) as defined in Code Section 414(p). 

  

	 	(b)	All amounts taken from a Participant’s Account, as provided in a QDRO, shall be immediately available to the Alternate Payee for withdrawal. Payments to Alternate
Payees will be made in accordance with procedures established by the Administrator. 

  

	14.3	DELAY OF DISTRIBUTION 

 In
the discretion of the Administrator, a Participant’s request to receive a distribution may be delayed for a period, not to exceed six months, if the Administrator has notice that part or all of the Participant’s Account may be subject to
alienation pursuant to a Qualified Domestic Relations Order. 
  

	14.4	FIDUCIARY BREACH OR CRIME 

At the direction of the Administrator, the Administrator may alienate a Participant’s interest in the Plan under certain cases

 INVESTMENT POLICY OF THE PLAN

  

	15.1	TRUSTEES OF THE PLAN 

PPG, on behalf of itself and as agent for its designated Subsidiary Corporations and Affiliates, shall enter into Trust Agreement(s) with
a corporation or association having trust powers to act as Trustee(s) under the Plan. The Board, or its designee, may, from time to time, remove such Trustee(s) or any successor Trustee(s) and such Trustee(s) or any successor Trustee(s) may resign.

  

	15.2	ADMINISTRATION 

  

	 	(a)	The Administrator shall have sole discretion and complete authority: 

  

	 	(1)	To determine eligibility for benefits in accordance with the provisions of the Plan; and 

 

	 	(2)	To correct administrative Account or Fund errors; and 

  

	 	(3)	To make factual findings; and 

  

	 	(4)	To construe the terms of the Plan; and 

  

	 	(5)	To control and manage the operation of the Plan; and 

  

	 	(6)	To suspend any confirmed transactions for transfers, fund reallocations, loans, withdrawals, distributions or other transactions requiring the sale of PPG Stock in the
event there are not sufficient funds immediately available to process such transactions in accordance with Section 4.2(d). 

  

	 	(b)	Subject to the limitations of the Plan, the Administrator from time to time shall establish rules for the administration and interpretation of the Plan and the
transaction of its business. The determination of the Administrator as to any disputed question shall be conclusive. All actions, decisions and interpretations of the Administrator in administering the Plan shall be performed in a uniform and
nondiscriminatory manner. 

  

	 	(c)	Claims and Appeal Procedures 

  

	 	(1)	This Section 15.2(c), in respect of all claims arising under the Plan other than with respect to the determination of whether a domestic relations order is
qualified pursuant to Section 14.2, shall supersede and preempt any and all procedures for settlement of disputes or resolutions of grievances under any other agreements or plans. 

  
 15.1

	 	(2)	Benefits shall be claimed by written application on a form filed in accordance with procedures established and uniformly applied by the Administrator or its delegate.
The Administrator shall make all determinations as to the right of any Participant, Beneficiary or Spouse to receive a benefit under the Plan and the amount of such benefit. The time, manner and form of distribution of such benefit shall occur in
accordance with the terms of the Plan. 

  

	 	(3)	If a claim is wholly or partially denied by the Administrator, written notice of the decision shall be furnished by the Administrator to the claimant within 90 days
after receipt of the claim or, if special circumstances require an extension of time for processing the claim, within 180 days after receipt of the claim (in which case notice of the delay will be given to the claimant during the initial 90-day
period). The notice containing the Administrator’s decision shall include: 

  

	 	(A)	The specific reason or reasons for the adverse decision with reference to the pertinent Plan provisions on which the denial is based; and 

 

	 	(B)	A description of additional material or information, if any, necessary to perfect such claim and a statement of why such material or information is necessary; and

  

	 	(C)	An explanation of the Plan’s review procedure, including any time limits applicable to such procedures; and 

 

	 	(D)	A statement of the claimant’s right to bring an action under ERISA Section 502(a) following an adverse benefit determination upon review.

  

	 	(4)	 If a claim is denied in whole or in part under this Section 15.2(c), the claimant shall have the right to request a full and fair review of the
denial. Such request must be made in writing and must be delivered to the Administrator within 60 days of receipt of the written notice of claim. In such review, the claimant or his duly authorized representative shall have the right to review any
pertinent Plan documents and to submit any issues or comments in writing. In addition, (A) the claimant shall have the right to submit documents, records and other information relating to the claim for benefits and (B) the claimant shall
be provided, upon request and free of charge, reasonable access to and copies of all documents, records and other information that is relevant to the claim for benefits. In the sole discretion of the Administrator, the Administrator or its delegate
may arrange to meet personally with the claimant and/or the claimant’s representative or have a written hearing for the purpose of understanding the claimant’s position and any related evidence that the claimant wishes to offer. In all
cases, the Administrator’s review of the appeal shall take 

  
 15.2

	 	 
into account all comments, documents, records and other information submitted by the claimant, without regard to whether such information was submitted or considered in the initial benefit
determination. 

 For purposes of the claim and appeal procedures contained in this Section 15.2(c)
information is considered “relevant” to a claimant’s claim if such document, record or other information (A) was relied upon in making the benefit determination without regard to whether such document, record or other information
was relied upon in making the determination or (B) demonstrates compliance with the Plan’s review procedures and that, if appropriate, the Plan provisions have been applied consistently with respect to similarly situated claimants.

  

	 	(5)	The Administrator, within 60 days after receipt of the request for review, or, in special circumstances such as where the Administrator in its sole discretion finds
there is a need to hold a hearing, within 120 days of receipt of the request for review (in which case notice of the delay will be given to the claimant during the initial 60-day period), shall give written notice of its decision to the claimant in
writing. The notice shall include specific reasons for the decision and specific references to the pertinent Plan provisions upon which the decision is based. In addition, the written notice of the decision denying a claim shall contain (A) a
statement that the claimant is entitled to receive, upon request and free of charge, reasonable access to and copies of all documents, records and other information that is relevant to the claimant’s claim for benefits and (B) a statement
of the claimant’s right to bring an action under ERISA Section 502(a). If the claim has not been granted and the notice is not furnished within the period of time specified above, the claim shall be deemed to be denied. The decision on
appeal shall be binding on all parties. 

  

	 	(d)	Every person receiving or claiming benefits under the Plan shall be conclusively presumed to be mentally and physically competent and of age. If the Administrator
determines that such person is mentally or physically incompetent or is a minor, payment shall be made to the legally appointed guardian, conservator or other person who has been appointed by a court of competent jurisdiction to care for the estate
of such person, provided that proper proof of such appointment is furnished in a form and manner suitable to the Administrator. Any payment made under the provisions of this paragraph (d) shall be a complete discharge of any liability therefor
under the Plan. The Administrator shall not be required to see to the proper application of any such payment. 

  

	 	(e)	The Administrator may employ counsel and other agents and may procure such clerical, accounting and other services as the Administrator may require in carrying out the
provisions of the Plan. 

  

	 	(f)	The Administrator shall not receive any compensation from the Plan for his services. 

  
 15.3

	 	(g)	The Corporation shall indemnify and save harmless the Administrator against all expenses and liabilities arising out of the Administrator’s service as such,
excepting only expenses and liabilities arising from the Administrator’s own gross negligence or willful misconduct, as determined by the Board. 

  

	 	(h)	For purposes of ERISA: 

  

	 	(1)	The “named fiduciary” for operation and administration of the Plan as provided in ERISA Section 402(a)(1) shall be the Administrator.

  

	 	(2)	The “named fiduciary” with respect to control and management of the assets of the Fund as provided in ERISA Section 402(c)(3) shall be the Executive
Committee and the Benefits Investment Committee. 

  

	 	(3)	The “administrator” of the Plan as provided in ERISA Section 3(16) shall be the Administrator. 

 

	 	(i)	The agent for service of legal process shall be the Secretary of PPG or the Administrator. 

 

	 	(j)	Any person or group of persons may serve in more than one fiduciary capacity with respect to the Plan. 

 

	15.3	ADMINISTRATIVE EXPENSES OF THE PLAN 

  

	 	(a)	The Administrator may charge to the Plan any or all fees, costs and expenses (collectively “Expenses”) incurred in administering the Plan that the
Administrator determines are reasonable and necessary to the administration of the Plan. 

  

	 	(b)	For purposes of explanation, but not for purposes of limitation, Expenses may include (1) fees charged by the Trustee, auditors, Financial Companies, Mutual Funds,
Investment Counsel and other accountants, actuaries, attorneys and consultants or advisors employed by the Administrator, (2) costs and expenses (both internal and external) associated with the administration of the Plan and (3) any fees
reimbursed from the Fund Manager Trustee to the Administrator for administrative services. Reimbursement may also include any interest earned on Participant’s funds while being held for Participant’s use subsequent to a withdrawal.

  

	 	(c)	The Administrator shall adopt rules for allocating the reimbursements and Expenses to the Funds and to Participants’ Accounts. Such rules shall be incorporated
herein as a part of this Plan and shall be applied in a uniform and nondiscriminatory manner. 

  

	 	(d)	Any Expenses that are not charged to the Plan shall be paid by the Corporation. 

  
 15.4

	15.4	PARTICIPANTS’ STATEMENTS 

 Each Participant shall be furnished regular statements of his Account showing his Savings, Elective Deferrals, Catch-Up Contributions and/or Company Contributions and the Gain or Loss attributable thereto
in each Fund other than the PPG Stock Fund, Matching Contributions in the PPG Stock Fund attributable to his Account and the Gain or Loss attributable thereto and the number of units and equivalent shares of PPG Stock allocated to his Account. Such
statements shall be issued quarterly. If a Participant believes that information on the statement is incorrect, he must notify the SPSC. Adjustments, if any, will be applied only to the beginning of the activity period covered by the most recent
statement. 
  

	15.5	ELECTIONS AND NOTICES 

Any election made or notice given by a Participant must be given in the manner and the time prescribed by the Administrator in the
procedure established by the Administrator. An election of any optional form(s) of benefit available under the Plan shall not be subject to any discretion by the Corporation or by the Administrator. 

 

	15.6	AMENDMENT, MODIFICATION, DISCONTINUANCE OR TERMINATION 

  

	 	(a)	PPG reserves the right, by action of the Board or by such other person or committee as may be designated by the Board acting in accordance with a procedure adopted and
approved by the Board, to amend or modify the Plan. No amendment or modification of the Plan shall reduce the amount credited to Participants’ Accounts or provide or have the effect of providing that the funds held in trust by the Trustees, or
the income thereof, may be used for or diverted to purposes other than for the exclusive benefit of Participants and their Beneficiaries. 

  

	 	(b)	PPG reserves the right, by action of the Board or by such other person or committee as may be designated by the Board acting in accordance with a procedure adopted and
approved by the Board, to terminate the Plan in its entirety, discontinue contributions under the Plan or terminate the participation in the Plan of the employees of any Corporation (other than PPG) or of any designated United States citizens or
foreign nationals employed by a foreign Subsidiary Corporation or a foreign Affiliate. Any Corporation (other than PPG) may terminate its participation in the Plan with respect to its employees or discontinue its contributions under the Plan for any
reason at any time. Upon termination or partial termination of the Plan or complete discontinuance of contributions as to any Participants, the amounts credited to the Accounts of affected Participants shall be nonforfeitable.

  

	 	(c)	Notwithstanding paragraphs (a) and (b) above, no amendment or modification of the Plan shall: 

 

	 	(1)	Reduce the amount credited to Participants’ Accounts; or 

  
 15.5

	 	(2)	Have the effect of providing that funds held in trust by the Trustee(s) or the income thereof may be used for or diverted to purposes other than for the exclusive
benefit of Participants and their Beneficiaries; or 

  

	 	(3)	Eliminate or reduce an early retirement benefit or retirement-type subsidy (as defined in Code Section 411(d)(6) and regulations thereunder) or eliminate an
optional form of benefit with respect to benefits attributable to service before the amendment, except as such amendment is permitted pursuant to Code Section 411(d)(6)(C) and regulations thereunder. 

 

	 	(d)	Notwithstanding paragraphs (a) and (b) above, the Plan may not be amended, modified or terminated, in whole or in part, so as to adversely affect the rights
of Participants, and the contributions of PPG under the Plan may not be discontinued or the formula by which the amount of the contributions of PPG is determined changed in a manner adverse to Participants, for a period of 24 months following a
Change in Control of PPG. As used herein, a “Change in Control” of PPG means the occurrence of any one of the following events: 

  

	 	(1)	A third person, including a “group” as such term is used in Section 13(d)(3) of the Securities Exchange Act of 1934 (the “Exchange Act”),
becomes the beneficial owner, directly or indirectly, of 20% or more of the combined voting power of PPG’s outstanding voting securities ordinarily having the right to vote for the election of directors of PPG unless such acquisition of
beneficial ownership is approved by a majority of the Incumbent Board (as such term is defined in paragraph (2) below); or 

  

	 	(2)	Individuals who constitute the board of Directors of PPG (the “Board”) as of January 1, 2000 (the “Incumbent Board”) cease for any reason to
constitute at least a majority of the board, provided that any person becoming a director subsequent to such date whose election or nomination for election by PPG’s shareholders was approved by a vote of at least a majority of the directors
comprising the Incumbent Board (other than an election or nomination of an individual whose initial assumption of office is in connection with an actual or threatened election contest relating to the election of the Directors of PPG, as such terms
are used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act) shall be, for purposes of this Plan, considered as through such person were a member of the Incumbent Board; or 

 

	 	(3)	The shareholders of PPG approve a transaction providing for: 

  

	 	(A)	The merger, consolidation or other combination of PPG with another corporation (other than a wholly-owned subsidiary) where PPG is not the surviving entity; or

  

	 	(B)	The sale of all or substantially all of the assets of PPG; or 

  
 15.6

	 	(C)	The liquidation or dissolution of PPG; or 

  

	 	(4)	A majority of the Board otherwise determines that a Change in Control has occurred. 

 

	 	(e)	Currently the Board has delegated to the Employee Benefits Committee the authority to adopt any change contemplated by this Section 15.6. 

 

	15.7	MERGER OR CONSOLIDATION 

  

	 	(a)	In the event of any merger or consolidation of the Plan with, or a transfer of the assets and liabilities of the Plan to, any other qualified plan, each Participant
must (if such other plan were terminated immediately after such merger, consolidation or transfer) receive a benefit under such other plan that is equal to or greater than the benefit he would have been entitled to receive under the Plan (if the
Plan had been terminated immediately prior to such merger, consolidation or transfer). Accordingly, upon any merger or consolidation of this Plan with, or transfer of assets or liabilities to, any other qualified plan, the last business day prior to
such merger, consolidation or transfer the Administrator shall perform the valuation and accounting procedures normally performed for Daily Valuation. All Account balances in this Plan shall thereupon be carried over into the merged, consolidated or
transferee plan, which shall contain provisions for full vesting of Accounts upon termination. 

  

	 	(b)	Notwithstanding the foregoing, this Plan shall not, through merger, consolidation or transfer of assets or liabilities, receive a direct or indirect transfer of a
Participant’s interest in a defined benefit plan, a defined contribution plan subject to the funding standards of Code Section 412 (other than an ESOP described in Code Section 401(a)(11)(C)), or any other defined contribution plan
that does not satisfy the requirements of Code Section 401(a)(11)(B)(iii), unless this Plan is first amended to satisfy the applicable joint and survivor annuity and qualified preretirement survivor annuity requirements of Code Sections
401(a)(11)(A) and 417. 

  

	 	(c)	Any such merger, consolidation or transfer must be specifically approved by the Employee Benefits Committee. 

 

	15.8	UNDELIVERABLE DISTRIBUTIONS 

 Each Participant and Beneficiary shall keep the Administrator advised of his current address. If a distribution to be made under the Plan is undeliverable because the Administrator is unable to locate the
Participant or Beneficiary to whom the distribution is to be made, the amount thereof shall be forfeited after the amount has remained undeliverable for 12 months after the date on which it first became distributable. Such forfeited amount shall be
applied to reduce any subsequent Company Contributions required under the Plan; or, if the Plan has been terminated, any amount not previously so applied shall be credited on a pro rated basis to the Accounts of all Participants at the time of such
termination. If such Participant or Beneficiary subsequently claims such 

  
 15.7

 
amount, he shall be entitled to receive a distribution from the Plan, in cash, equal to such amount plus interest from the date such amount was applied to reduce the amount of the Company
Contributions at the rate such amount would have earned had it been invested in the stable value. To provide for such distribution the Corporation shall make a contribution to the Plan equal to the amount to be distributed or, if the Plan has been
terminated, the Corporation shall make a payment to such Participant or Beneficiary. 
  

	15.9	CONSTRUCTION 

  

	 	(a)	The Plan is intended to conform to the applicable requirements of ERISA and the Code. Except to the extent otherwise provided in ERISA and the Code, this Plan shall be
construed, regulated and administered under the laws of the Commonwealth of Pennsylvania (including its statute of limitations provisions but excluding its choice of law provisions). 

 

	 	(b)	As used herein, the masculine shall include the feminine and the singular shall include the plural, and vice versa, unless the context clearly indicates otherwise.

  

	 	(c)	The headings are included solely for convenience of reference. If there is any conflict between such headings and the text of the Plan, the text shall control.

  

	15.10	CONTRACT OF EMPLOYMENT 

The adoption and maintenance of the Plan and Trust shall not be deemed to be a contract between the Corporation and any of its employees.
Nothing contained herein shall be deemed to give to any employee the right to be retained in the employ of the Corporation or to interfere with the right of the Corporation to discharge any of its employees at any time for any reason; nor shall it
be deemed to give to the Corporation the right to require any employee to remain in its employ nor shall it interfere with the employee’s right to terminate his employment at any time. 

 

	15.11	EMPLOYEE STOCK OWNERSHIP PLAN 

 The portion of the Plan that is invested in PPG Stock is an employee stock ownership plan and is operated and interpreted in accordance with Code Section 4975(e)(7) and the regulations promulgated
thereunder. The Plan also complies with ERISA Section 404(c) except for the confidential voting of PPG Stock. 
  

	15.12	PUT OPTION REQUIREMENTS 

  

	 	(a)	PPG Stock that is acquired with the proceeds of an Acquisition Loan and that is not publicly traded when distributed, or if it is subject to a trading limitation when
distributed, shall be subject to a put option. For purposes of this paragraph (a), a “trading limitation” on PPG Stock is a restriction under any federal or state securities law or any regulation thereunder, or an agreement affecting
PPG Stock that would make PPG Stock not as freely tradable as stock not subject to such restriction. 

  
 15.8

	 	(b)	The put option may be exercised only by a Participant or a Participant’s Beneficiary (including an estate) to whom PPG Stock passes by reason of a
Participant’s death. The put option shall permit a Participant to put the PPG Stock to the Corporation. Under no circumstances may the put option bind the Plan. However, the Plan shall have the option to assume the rights and obligations of the
Corporation at the time that the put option is exercised. If it is known at the time a loan is made that federal or state law will be violated by the Corporation’s honoring such put option, the put option shall permit the PPG Stock to be put,
in a manner consistent with such law, to a third party (e.g., an Affiliate or a shareholder other than the Plan) that has substantial net worth at the time the loan is made and whose net worth is reasonably expected to remain substantial.

  

	 	(c)	The put option shall commence as of the day following the date the PPG Stock is distributed to the Participant and end 60 days thereafter and if not exercised within
such 60-day period, an additional 60-day option shall commence on the first day of the fifth month of the Plan Year next following the date the stock was distributed to the Participant (or such other 60-day period as provided in regulations
promulgated by the Secretary of the Treasury). However, in the case of PPG Stock that is publicly traded without restrictions when distributed but ceases to be so traded within either of the 60-day periods described herein after distribution, the
Corporation shall notify each holder of such PPG Stock in writing on or before the tenth day after the date PPG Stock ceases to be so traded that for the remainder of the applicable 60-day period PPG Stock is subject to the put option. The number of
days between the tenth day and the date on which notice is actually given, if later than the tenth day, shall be added to the duration of the put option. The notice shall inform distributees of the term of the put options that they are to hold. The
terms shall satisfy the requirements of this Section 15.12. 

  

	             (d) 
	(1)	 The put option is exercised by the holder’s notifying the Corporation in writing that the put option is being exercised; the notice
shall state the name and address of the holder and the number of shares to be sold. 

  

	 	(2)	The Period during which a put option is exercisable does not include any time when a distributee is unable to exercise it because the party bound by the put option is
prohibited from honoring it by applicable federal or state law. 

  

	 	(3)	The price at which a put option must be exercisable is the value of PPG Stock determined in accordance with Treasury Regulation Section 54.4975-11(d)(5).

  

	 	(4)	 The provisions for payment under the put option shall be reasonable. The deferral of payment is reasonable if adequate security and a reasonable
interest rate are provided for any credit extended and if the cumulative payments at any time are no less than the aggregate of reasonable periodic payments as of such time. Periodic payments are reasonable if annual

  
 15.9

	 	 
installments, beginning within 30 days after the date the put option is exercised, are substantially equal. Generally, the payment period may not end more than five years after the date the put
option is exercised. However, it may be extended to a date no later than the earlier of ten years from the date the put option is exercised or the date the proceeds of the loan used by the Plan to acquire the PPG Stock subject to such put option are
entirely repaid. 

  

	 	(5)	Payment under a put option shall not be restricted by the provisions of a loan or any other arrangement, including the terms of the Corporation’s articles of
incorporation, unless so required by applicable state law. 

  

	 	(e)	An arrangement involving the Plan that creates the put option shall not provide for the issuance of put options other than as provided under this Section 15.12.
The Plan (and the Trust Fund) must not otherwise obligate itself to acquire PPG Stock from a particular holder thereof at an indefinite time determined upon the happening of an event such as the death of the holder. 

 

	 	(f)	Notwithstanding any other provision of the Plan regarding a Participant’s right to exercise a put option, in the case of a distribution of Employer Securities that
are not readily tradable on an established securities market, the Plan shall provide the Participant with a put option that complies with the requirements of Code Section 409(h). Such put option shall provide that if a Participant exercises the
put option, the Corporation, or the Plan if the Plan so elects, shall repurchase the Employer Securities as follows: 

  

	 	(1)	If the distribution constitutes a Total Distribution, payment of the fair market value of a Participant’s Account balance shall be made in five substantially equal
annual payments. The first installment shall be paid not later than 30 days after the Participant exercises the put option. The Plan will pay a reasonable rate of interest and provide adequate security on amounts not paid after 30 days.

  

	 	(2)	If the distribution does not constitute a Total Distribution, the Plan shall pay the Participant an amount equal to the fair market value of the Employer Securities
repurchased no later than 30 days after the Participants exercises the put options. 

  

	15.13	INDEPENDENT APPRAISER 

All valuations of Employer Securities that are not readily tradable on an established securities market with respect to activities carried
on by the Plan shall be made by an independent appraiser meeting requirements similar to those contained in regulations under Code Section 170(a)(1). 
  

	15.14	LOANS TO THE TRUST 

  

	 	(a)	The Plan may borrow money for any lawful purpose, provided the proceeds of an Acquisition Loan are used within a reasonable time after receipt only for any or all of
the following purposes: 

  

	 	(1)	To acquire PPG Stock; or 

  
 15.10

	 	(2)	To repay such loan; or 

  

	 	(3)	To repay a prior Acquisition Loan. 

  

	 	(b)	All loans to the Trust that are made or guaranteed by a disqualified person must satisfy all requirements applicable to exempt loans as set forth in Code
Section 4975(e)(7). 

  

	 	(c)	The terms of each Acquisition Loan must, at the time the loan is made, be at least as favorable to the Trust as the terms of a comparable loan resulting from arm’s
length negotiations between independent parties. Each Acquisition Loan shall be for a specific term and shall bear a reasonable rate of interest. An Acquisition Loan may be secured by a pledge of the Employer Securities acquired with the proceeds of
the Acquisition Loan (or acquired with the proceeds of a prior Acquisition Loan that is being refinanced). No other Trust assets may be pledged as collateral for an Acquisition Loan, and no lender shall have recourse against Trust assets other than:

  

	 	(1)	Collateral given for the Acquisition Loan; and 

  

	 	(2)	Company Contributions in the form of Loan Payments made pursuant to Section 3.4; and 

 

	 	(3)	Earnings attributable to such collateral and the investment of such Company Contributions. 

An Acquisition Loan shall not be payable on demand except in the event of default. In the event of default of an Acquisition Loan, the
value of Plan assets transferred in satisfaction of the Acquisition Loan shall not exceed the amount of default. If the lender is a disqualified person within the meaning of Code Section 4975(e)(2), the Acquisition Loan must provide for a
transfer of Trust assets on default only upon and to the extent of the failure of the Trust to meet the payment schedule of the Acquisition Loan. Payments of principal and/or interest on any Acquisition Loan shall be made by the ESOP Trustee only
from Matching Contributions in the form of Loan Payments, from earnings attributable to such contributions, from any cash dividends received by the Trust with respect to PPG Stock acquired with the proceeds of an Acquisition Loan, in appropriate
circumstances, from the proceeds from the disposition of PPG Stock acquired with the proceeds of an Acquisition Loan and, in accordance with Section 3.4(f)(2), from Dividends otherwise payable on shares of PPG Stock allocated to
Participants’ Accounts. 
  

	 	(d)	 In acquiring PPG Stock, the ESOP Trustee shall take all appropriate and 

  
 15.11

	 	 
necessary measures to ensure that the Trust pays no more than “adequate consideration” (within the meaning of ERISA Section 3(18)) for such securities. All PPG Stock acquired with
the proceeds of an Acquisition Loan shall be placed in the Suspense Account established by the ESOP Trustee. To the extent required for the purpose of pledging such PPG Stock as collateral for the Acquisition Loan, the shares held as collateral in
the Suspense Account and the Released But Not Allocated Account may be physically segregated from other Trust assets. Any pledge of PPG Stock must provide for the release of the securities so pledged as payments on the Acquisition Loan are made by
the ESOP Trustee and for such securities to be allocated to Participants pursuant to Sections 3.1 and/or 3.2. 

  

	 	(e)	Except as otherwise permitted in Section 15.12, no PPG Stock acquired with the proceeds of an Acquisition Loan shall be subject to any put, call or other option or
any buy-sell or similar agreement while held by and when distributed from the Trust, whether or not the Plan constitutes an “employee stock ownership plan” within the meaning of Code Section 4975(e)(7) at such time and whether or not
the Acquisition Loan has been repaid at such time. 

  
 15.12

 SECTION 16 
 LIMITATIONS ON CONTRIBUTIONS 
 AND BENEFITS 

 

	16.1	FEDERAL LAW LIMITS 

 In no
event shall Company Contributions, Savings, Catch-Up Contributions and/or Elective Deferrals exceed any applicable limitation imposed by federal law. 
  

	16.2	DEFINITIONS 

 For purposes
of this Section 16 only, the following words and phrases shall have the following meanings: 
  

	 	(a)	 ACTUAL DEFERRAL PERCENTAGE means, with respect to an Eligible Employee for a Plan Year, the ratio (expressed as a percentage), of Elective
Deferrals on behalf of the Eligible Employee for the Plan Year to the Eligible Employee’s Compensation for the Plan Year. For purposes of the ADP test, Elective Deferrals shall be taken into account for a Plan Year only if such Deferrals relate
to Compensation that either would have been received by the Participant but for the deferral election or is attributable to services performed by the Participant in the Plan Year and would have been received by the Participant within
2 1/2 months after the close of the Plan Year but
for the deferral election. 

  

	 	(b)	ANNUAL ADDITIONS mean the amount allocated to a Participant’s Account in this Plan and in any other defined contribution retirement plan maintained by the
Corporation during the Limitation Year that constitutes: 

  

	 	(1)	Company Contributions; and 

  

	 	(2)	Employee Contributions (Savings and/or Elective Deferrals); and 

  

	 	(3)	Forfeitures; and 

  

	 	(4)	Amounts described in Code Sections 415(l)(1) and 419(A)(d)(2). 

 In the event Company Contributions are made in the form of Loan Payments, Annual Additions shall include only the amount of principal paid by such Loan Payments. 

Annual Additions shall not include any amount added to a Participant’s Account in accordance with Section 3.4(f)(2) and
restorative payments as defined under Treasury Regulation Section 1.415(c)-1(b)(2)(ii)(C). 
  

	 	(c)	AVERAGE ACTUAL DEFERRAL PERCENTAGE (“ADP”) means, with respect to a Plan Year, the average (expressed as a percentage) of the Actual Deferral
Percentages of the Eligible Employees for such Plan Year. 

  
 16.1

	 	(d)	AVERAGE CONTRIBUTION PERCENTAGE (“ACP”) means, with respect to a Plan Year, the average (expressed as a percentage) of the Contribution Percentages of
the Eligible Employees for such Plan Year. 

  

	 	(e)	 COMPENSATION means compensation as defined in Code Section 415, including (1) amounts paid after a Participant’s severance from
employment with the Employer, provided the amounts are paid by the later of 2 1/2 months after severance from employment or the end of the limitation year that includes the date of severance from employment and (A) the amounts paid would have been otherwise included in the
definition of Compensation if they were paid prior to the Participant’s severance from employment with the Employer; (B) the amounts paid are payments for unused accrued bona fide sick, vacation or other leave, but only if the Participant
would have been able to use the leave if employment had continued; and (C) the amounts paid are payments received by a Participant pursuant to a nonqualified unfunded deferred compensation plan, but only to the payment would have been paid to
the Participant at the same time if the Participant had continued his employment with the Employer and only to the extent that the payment is includible in the Participant’s gross income; (2) amounts paid to a Participant to the extent
excludible from the Participant’s gross income on account of the location of the services or because all amounts paid by the Employer with respect to the Participant are excluded from gross income; provided, however, that such amounts shall not
be treated as Compensation to the extent they are not effectively connected to the conduct of a trade or business in the United States; (3) amounts includible in the gross income of the Participant under the rules of Code Section 409A or
457(f)(1)(A) or because the amounts are constructively received by the Participant; and (4) payments made to an individual who does not currently perform services for the Employer by reason of qualified military service (as that term is used in
Code Section 414(u)(1)) or disability to the extent those payments do not exceed the amounts the individual would have received if the individual had continued to perform services for the Employer rather than entering military service or
becoming disabled. 

 The annual Compensation of each Participant taken into account in determining
allocations for any Plan Year beginning after December 31, 2008 shall not exceed $245,000, as adjusted for cost-of-living increases in accordance with Code Section 401(a)(17)(B). Annual Compensation means Compensation during the Plan Year
or such other consecutive 12-month period over which Compensation is otherwise determined under the Plan (the “determination period”). The cost-of-living adjustment in effect for a calendar year applies to annual Compensation for the
determination period that begins with or within such calendar year. 
  

	 	(f)	CONTRIBUTION PERCENTAGE means, with respect to an Eligible Employee for a Plan Year, the ratio (expressed as a percentage) of the sum of the Savings and Matching
Contributions under the Plan on behalf of the Eligible Employee for the Plan Year to the Eligible Employee’s Compensation for the Plan Year.

described in Code Section 414(n)(5) unless otherwise provided by the terms of this Plan other than in this Section 16. 

  

	 	(i)	EMPLOYER SECURITIES means stock described in Code Section 4975(e)(8) or in Treasury Regulations Section 54.4975-12. 

 

	 	(j)	EXCESS AGGREGATE CONTRIBUTIONS means the amount described in Code Section 401(m)(6)(B). 

 

	 	(k)	EXCESS CONTRIBUTIONS means the amount described in Code Section 401(k)(8)(B).

Section 16.12(b). 

  

	 	(m)	HIGHLY COMPENSATED EMPLOYEE means a highly compensated employee as defined in Code Section 414(q) and the regulations promulgated pursuant thereto.

  

	 	(1)	Generally, a Highly Compensated Employee means a highly compensated active employee and highly compensated former employee who:

for such 

  
 16.3

	 	 
preceding year, was in the top-paid group of Employees for such preceding year. For this purpose, an Employee is in the top-paid group of Employees for any year if such Employee is in the group
consisting of the top 20% of the Employees when ranked on the basis of compensation paid during such year. 

  

	 	(2)	For purposes of this definition, compensation means compensation within the meaning of Code Section 415(c)(3). 

 

	 	(3)	For purposes of this definition, Employees who are non-resident aliens and who have no earned income (as defined in Code Sections 911(d)(2)) that constitutes income
from sources within the United States (under Code Section 861(a)(3)) shall be excluded from consideration as Employees. 

  

	 	(4)	 In determining the top 20% of Employees for purposes of paragraph (1)(B), the following Employees shall be excluded: (A) Employees who have
not completed six months of service; (B) Employees who normally work less than 17 1/2 hours per week; (C) Employees who normally work less than six months during any year; (D) Employees who have not attained age 21; and (E) except to the extent provided in regulations of
the Secretary of the Treasury, Employees included in a unit of employees covered by a collective bargaining agreement between an Affiliated Company and employee representatives. 

 

	 	(5)	A former Employee will be deemed to be a Highly Compensated Employee if he was a Highly Compensated Employee either (A) at the time of his Termination of
Employment or (B) at any time after reaching age 55. 

  

	 	(n)	LEASED EMPLOYEE means any person (other than an Employee of the Corporation) who pursuant to an agreement between the Corporation and any other person
(“leasing organization”) has performed services for the Corporation (or for the Corporation and related persons determined in accordance with Code Section 414(n)(6)) on a substantially full-time basis for a period of at least one year
and such services are performed under the primary direction or control of the Corporation.

	 	(a)	Any contribution for medical benefits after separation from service (within the meaning of Code Section 401(h) or 419A(f)(2)) that is otherwise treated as an
Annual Addition, or 

  

	 	(b)	Any amount otherwise treated as an Annual Addition under Code Section 415(l)(1). 

 

	16.5	MAXIMUM AMOUNT OF ELECTIVE DEFERRALS 

 No Employee shall be permitted to have Elective Deferrals made under this Plan during any calendar year in excess of $16,500 or the applicable amount determined in accordance with Code
Section 402(g). 
  

	16.6	AVERAGE ACTUAL DEFERRAL PERCENTAGE 

  

	 	(a)	Effective January 1, 2009, the Average Actual Deferral Percentage for Eligible Employees who are Highly Compensated Employees for the current Plan Year shall not
exceed the Average Actual Deferral Percentage for the current Plan Year for eligible Employees who are Non-Highly Compensated Employees for the current Plan Year multiplied by 1.25; or 

 

	 	(b)	The Average Actual Deferral Percentage for Eligible Employees who are Highly Compensated Employees for the current Plan Year shall not exceed the Average Actual
Deferral Percentage for the current Plan Year for Eligible Employees who are Non-Highly Compensated Employees for the current Plan Year multiplied by two, provided that the Average Actual Deferral Percentage for Eligible Employees who are Highly
Compensated Employees does not exceed the Average Actual Deferral Percentage for the current Plan Year for Eligible Employees who are Non-Highly Compensated Employees for the current Plan Year by more than two percentage points.

  

	16.7	MULTIPLE PLANS 

  

	 	(a)	For purposes of this Section 16, the Actual Deferral Percentage for any Eligible Employee who is a Highly Compensated Employee for the Plan Year and who is
eligible to have Elective Deferrals allocated to his Account under two or more plans or arrangements described in Code Section 401(k) that are maintained by the Corporation or an Affiliate shall be determined as if all such Elective Deferrals
were made under a single arrangement. 

  
 16.5

	 	(b)	The determination and treatment of the Elective Deferrals and Actual Deferral Percentage of any Participant shall satisfy such other requirements as may be prescribed
by the Secretary of Treasury. 

  

	16.8	AVERAGE CONTRIBUTION PERCENTAGE 

  

	 	(a)	Effective January 1, 2008, the Average Contribution Percentage for Eligible Employees who are Highly Compensated Employees for the current Plan Year shall not
exceed the Average Contribution Percentage for the current Plan Year for Eligible Employees who are Non-Highly Compensated Employees for the current Plan Year multiplied by 1.25; or 

 

	 	(b)	The Average Contribution Percentage for Eligible Employees who are Highly Compensated Employees for the current Plan Year shall not exceed the Average Contribution
Percentage for the current Plan Year for Eligible Employees who are Non-Highly Compensated Employees for the current Plan Year multiplied by two, provided that the Average Contribution Percentage for Eligible Employees who are Highly Compensated
Employees does not exceed the Average Contribution Percentage for the current Plan Year for Eligible Employees who are Non-Highly Compensated Employees for the current Plan Year by more than two percentage points. 

 

	16.9	SPECIAL RULES 

  

	 	(a)	For purposes of this Section 16, the Contribution Percentage for any Eligible Employee who is a Highly Compensated Employee for the Plan Year and who is eligible
to make Employee Contributions or to receive Company Contribution or Elective Deferrals allocated to his Account under two or more plans described in Code Section 401(a) or arrangements described in Code Section 401(k) that are maintained
by the Corporation or an Affiliate shall be determined as if all such contributions and Elective Deferrals were made under a single plan. 

  

	 	(b)	In the event that this Plan satisfied the requirements of Code Section 410(b) only if aggregated with one or more plans, or if one or more other plans satisfy the
requirements of Code Section 410(b) only if aggregated with this Plan, then this Section 16 shall be applied by determining the Contribution Percentages of Eligible Employees as if all such plans were a single plan.

  

	 	(c)	The determination and treatment of the Contribution Percentage of any Participant shall satisfy such other requirements as may be prescribed by the Secretary of
Treasury. 

  

	 	(d)	For purposes of this Section 16.9, the Administrator shall take the appropriate action steps necessary to limit Highly Compensated Employee contribution rates.

  

	16.10	QUALIFIED VOLUNTARY EMPLOYEE CONTRIBUTIONS 

 The Plan shall accept no Employee Contributions designated by the Participant as deductible employee contributions (within the meaning of Code Section 72(o)(5)(A)) for a taxable year of the
Participant beginning after December 31, 1986. 

  
 16.6

	16.11	DISTRIBUTION OF EXCESS DEFERRALS 

  

	 	(a)	Notwithstanding any other provision of the Plan, Excess Deferral Amounts and income allocable thereto for the Plan Year for which said Excess Deferral Amounts were
made, but not for any period between the close of such Plan Year and the date said Excess Deferral Amounts are distributed, shall be distributed no later than each April 15 to Participants who claim such allocable Excess Deferral Amounts for
the preceding Year. 

  

	 	(b)	The Participant’s claim shall (1) be in writing, (2) be submitted to the Administrator no later than March 1, (3) specify the
Participant’s Excess Deferral Amount for the preceding Year and (4) be accompanied by the Participant’s written statement that if such amounts are not distributed, such Excess Deferral Amount, when added to amounts deferred under
other plans or arrangements described in Code Section 401(k), 408(k) or 403(b), exceeds the limit imposed on the Participant by Code Section 402(g) for the year in which the deferral occurred. 

 

	 	(c)	Maximum Distribution Amount 

 The Excess Deferral Amount distributed to a Participant with respect to a Plan Year shall be adjusted for income allocable thereto for the Plan Year for which said Excess Deferral Amount was made, but not
for any period between the close of such Plan Year and the date said Excess Deferral Amount is distributed, and, if there is a Loss allocable to the Excess Deferral, shall in no event be less than the lesser of the Participant’s Account under
the Plan or the Participant’s Elective Deferrals for the Plan Year. 
  

	16.12	DISTRIBUTION OF EXCESS CONTRIBUTIONS 

  

	 	(a)	Notwithstanding any other provisions of the Plan, Excess Contributions and income allocable thereto for the Plan Year for which said Excess Contributions were made, but
not for any period between the close of such Plan Year and the date said Excess Contributions are distributed, shall be distributed no later than the last day of each Plan Year to Participants on whose behalf such Excess Contributions were made for
the preceding Plan Year. 

  

	 	(b)	Determination of Income 

The income allocable to Excess Contributions shall be determined by multiplying income allocable to the Participant’s Elective
Deferrals for the Plan Year by a fraction, the numerator of which is the Excess Contribution on behalf of the Participant for the preceding Plan Year and the denominator of which is the sum of the Participant’s Account balances attributable to
Elective Deferrals on the last day of the preceding Plan Year. 

  
 16.7

	 	(c)	Maximum Distribution Amount 

 The Excess Contributions that would otherwise be distributed to the Participant shall be adjusted for income for the Plan Year for which said Excess Deferral Amounts were made, but not for any period
between the close of such Plan Year and the date said Excess Deferral Amounts are distributed, shall be reduced, in accordance with regulations, by the amount of Excess Deferrals distributed to the Participant and shall, if there is a Loss allocable
to the Excess Contributions, in no event be less than the lesser of the Participant’s Account under the Plan or the Participant’s Elective Deferrals for the Plan Year. 

 

	 	(d)	Accounting for Excess Contributions 

 Amounts distributed under this Section 16 shall first be treated as distributions from the Participant’s Elective Deferral Account. 

 

	 	(e)	The amount of a Highly Compensated Employee’s Excess Contributions will be determined in the following manner. The amount by which the Actual Deferral Percentage
of the Highly Compensated Employee with the highest Actual Deferral Percentage would have to be reduced to satisfy the ADP test or cause such percentage to equal the Actual Deferral Percentage of the Highly Compensated Employee with the next highest
percentage shall be determined. This process shall be repeated until the ADP test would be satisfied. The amount of Excess Contributions is equal to the sum of these hypothetical reductions multiplied, in each case, by the Highly Compensated
Employee’s Compensation. The identity of the Highly Compensated Employees subject to distribution (or recharacterization) of Excess Contributions will be determined using the “dollar leveling method” starting with the Highly
Compensated Employee with the greatest dollar amount of elective and other contributions treated as elective contributions for the Plan Year until the amount of Excess Contributions have been accounted for. The amount of Excess Contributions to be
distributed (or recharacterized) shall be reduced by Excess Deferral Amounts previously distributed for the taxable year ending in the same Plan Year and Excess Deferral Amounts to be distributed for a taxable year will be reduced by Excess
Contributions previously distributed or recharacterized for the Plan Year beginning in such taxable year. 

  

	 	(f)	 Notwithstanding the foregoing, if a Participant who is eligible to make Catch-Up Contributions, as described under Section 2.7 of this Plan, is
determined to have made Excess Contributions during such Plan Year, the portion of such excesses that consist solely of such Participant’s Elective Deferral Contributions shall first be treated as Catch-Up Contributions, subject to applicable
limitations under Code Section 414(v) and subject to Proposed Treasury Regulation Section 1.414(v)-1. After such excesses are first treated as Catch-Up Contributions to the extent permissible, the elimination of any additional such
excesses shall be made in accordance with the rules described in the preceding paragraphs. If any Elective Deferral Contributions are treated as Catch-Up 

  
 16.8

	 	 
Contributions under this Section 16.12(f), such treatment shall be accompanied by a forfeiture of the corresponding Matching Contributions, if any. In addition, any income or losses
allocable to excesses that are treated as Catch-Up Contributions under this Section 16.12(f) shall be treated as income or losses attributable to such Catch-Up Contributions and shall not be subject to distribution under the prior provisions of
this Section 16.12. 

  

	16.13	DISTRIBUTION OF EXCESS AGGREGATE CONTRIBUTIONS 

  

	 	(a)	Excess Aggregate Contributions and income allocable thereto for the Plan Year for which said Excess Aggregate Contributions were made, but not for any period between
the close of such Plan Year and the date said Excess Aggregate Contributions are distributed, shall be forfeited, if otherwise forfeitable under the terms of this Plan or, if not forfeitable, distributed no later than the last day of each Plan Year
to Participants to whose Accounts Employee Contributions or Matching Contributions were allocated for the preceding Plan Year. 

 For purposes of this Section 16.13, the allocable Gain or Loss for the period between the end of the Plan Year and the date of correction shall not be taken into consideration when determining the
income allocable to Excess Aggregate Contributions. 
  

	 	(b)	Determination of Income 

The income allocable to Excess Aggregate Contributions shall be determined by multiplying the income allocable to the Participant’s
Employee Contributions and Matching Contributions for the Plan Year by a fraction, the numerator of which is the Excess Aggregate Contributions on behalf of the Participant for the Plan Year and the denominator of which is the sum of the
Participant’s Account balance attributable to Employee Contributions and Matching Contributions as of the beginning of the Plan Year plus Employee Contributions and Matching Contributions for the Plan Year. 

 

	 	(c)	Maximum Distribution Amount 

 The Excess Aggregate Contributions to be distributed to a Participant shall be adjusted for income for the Plan Year for which said Excess Aggregate Contributions were made, but not for any period between
the close of such Plan Year and the date said Excess Aggregate Contributions are distributed and, if there is a Loss allocable to the Excess Aggregate Contribution, shall in no event be less than the lesser of the Participant’s Account under
the Plan or the Participant’s Employee Contributions and Matching Contributions for the Plan Year. 
  

	 	(d)	Accounting for Excess Aggregate Contributions 

 Excess Aggregate Contributions shall be distributed from the Participant’s Employee Contribution account and forfeited if otherwise forfeitable under the

  
 16.9

 
terms of the Plan (or, if not forfeitable, distributed) from the Participant’s Matching Contribution account in proportion to the Participant’s Employee Contributions and Matching
Contributions for the Plan Year. 
  

	 	(e)	The amount of a Highly Compensated Employee’s Excess Aggregate Contributions will be determined in the following manner. The amount by which the Contribution
Percentage of the Highly Compensated Employee with the highest Contribution Percentage would have to be reduced to satisfy the ACP test or cause such percentage to equal the Contribution Percentage of the Highly Compensated Employee with the next
highest percentage shall be determined. This process shall be repeated until the ACP test would be satisfied. The amount of Excess Aggregate Contributions is equal to the sum of these hypothetical reductions multiplied, in each case, by the Highly
Compensated Employee’s Compensation. The identity of the Highly Compensated Employees subject to distribution (or recharacterization) of Excess Aggregate Contributions will be determined using the “dollar leveling method” starting
with the Highly Compensated Employee with the greatest dollar amount (determined after the distribution of any Excess Aggregate Contributions) of contributions taken into account in calculating the ACP test for the Plan Year until the amount of
Excess Aggregate Contributions have been accounted for. Forfeitures of Excess Aggregate Contributions shall not be allocated to Participants whose contributions are reduced in accordance with Section 16.12 and/or 16.13.

  

	16.15	ALLOCATION OF FORFEITURES 

  

	 	(a)	Amounts forfeited by Highly Compensated Employees under this Section 16 shall be treated as Annual Additions and either: 

 

	 	(1)	Applied to reduce Company Contributions if forfeitures of Company Contributions under the Plan are applied to reduce Company Contributions; or 

 

	 	(2)	Allocated, after all other forfeitures under the Plan and subject to Section 16.15(b), to the same Participants and in the same manner as such other forfeitures of
Company Contributions are allocated to other Participants under the Plan. 

  

	 	(b)	Notwithstanding the foregoing, no forfeitures arising under this Section 16 shall be allocated to the Account of any Highly Compensated Employee.

  

	16.16	REDUCTION OF HIGHLY COMPENSATED EMPLOYEE ELECTIVE DEFERRALS OR SAVINGS 

 Notwithstanding any provisions of the Plan, the maximum amount of Elective Deferrals or Savings of Participants who are Highly Compensated Employees may be reduced from time to time by the Administrator
so as to enable the Plan to meet the nondiscrimination requirements of the Code. The Administrator shall prescribe the manner and procedures to determine a Participant’s status as a Highly Compensated Employee, the applicable determination year
and the manner and procedures by which any such reductions shall be carried out. 

  
 16.10

	16.17	RS COGEN SAFE HARBOR 

 The
portion of the Plan benefiting Participants who are employed by RS CoGen LLC is intended to comply with the safe harbor provisions of Code Sections 401(k)(12) and 401(m)(10). Accordingly, notwithstanding any other provision of the Plan, such
Participants (including any Elective Deferral, Savings contributions or Company Contributions made by such Participants or on behalf of such Participants) shall be disregarded for purposes of the ADP and ACP Tests. 

  
 16.11

 SECTION 17 
 TOP-HEAVY PROVISIONS 
 This Section 17 shall become operative for a Plan Year and
shall supersede any conflicting provisions of the Plan only if, on the last day of the preceding Plan Year, the Administrator determines that the Plan is a Top-Heavy Plan. 

 

	17.1	TOP-HEAVY RATIO 

  

	 	(a)	If the Corporation maintains one or more defined contribution plans (including any Simplified Employee Pension Plan) and the Corporation has never maintained any
defined benefit plan that has covered or could cover a Participant in this Plan, the Top-Heavy Ratio is a fraction, the numerator of which is the sum of the Account balances of all Key Employees as of the Determination Date (including any part of
any Account balance distributed in the five-year period ending on the Determination Date) and the denominator of which is the sum of all Account balances (including any part of any Account balance distributed in the five-year period ending on the
Determination Date) of all Participants as of the Determination Date. Both the numerator and denominator of the Top-Heavy Ratio are adjusted to reflect any contribution that is due but unpaid as of the Determination Date. For purposes of this
paragraph (a), the Account balances of an employee shall be increased by any distributions made to such employee during the one-year period ending on the Determination Date (or, in the case of distributions made for reasons other than severance from
employment, death and disability, the five-year period ending on the Determination Date). 

  

	 	(b)	If the Corporation maintains or has maintained one or more defined benefit plans that have covered or could cover a Participant in this Plan, the Top-Heavy Ratio is a
fraction, the numerator of which is the sum of Account balances under the defined contribution plans for all Key Employees and the Present Value of accrued benefits under the defined benefit plan for all Key Employees, and the denominator of which
is the sum of the Account balances under the defined contribution plans for all Participants and the Present Value of accrued benefits under the defined benefit plans for all Participants. Both the numerator and denominator of the Top-Heavy Ratio
are adjusted for any distribution of an Account balance of an accrued benefit made in the one-year period ending on the Determination Date and any contribution due but unpaid as of the Determination Date. 

 

	 	(c)	For purposes of paragraphs (a) and (b) above, the value of Account balances and the Present Value of accrued benefits will be determined as of the most recent
Valuation Date that falls within or ends with the 12-month period ending on the Determination Date. 

  
 17.1

	 	(d)	The Account balance and accrued benefit of a Participant who is not a Key Employee but who was a Key Employee in a prior year will be disregarded. The calculation of
the Top-Heavy Ratio and the extent to which distributions, rollovers and transfers are taken into account will be made in accordance with Code Section 416 and the regulations thereunder. Nondeductible voluntary Participant contributions are
included in the computation. Deductible employee contributions will not be taken into account for purposes of computing the Top-Heavy Ratio. The Account balance of a former Participant who has not performed any service for the Corporation (except
Plan benefits) over the one-year period ending on the Determination Date, shall be disregarded. When aggregating plans, the value of Account balances and accrued benefits will be calculated with reference to the Determination Dates that fall within
the same year. 

  

	17.2	PERMISSIVE AGGREGATION GROUP means the Required Aggregation Group of plans plus any other plan or plans of the Corporation that, when considered as a group with
the Required Aggregation Group, would continue to satisfy the requirements of Code Sections 401(a)(4) and 410. 

  

	17.3	REQUIRED AGGREGATION GROUP means: 

  

	 	(a)	Each qualified plan of the Corporation, including any terminated plan that was maintained by the Corporation any time within the one-year period ending on the
Determination Date in which at least one Key Employee participates; and 

  

	 	(b)	Any other qualified plan of the Corporation that enables a plan described in (a) above to meet the requirements of Code Sections 401(a)(4) or 410.

  

	17.4	DETERMINATION DATE means the last day of the preceding Plan Year. 

  

	17.5	VALUATION DATE means, for purposes of this Section 17, the last day of the Plan Year. 

 

	17.6	PRESENT VALUE means, for purposes of calculating the Top-Heavy Ratio, the value based on an interest rate of 5% per annum and mortality according to the
1984 Unisex Pension Mortality Table. 

  

	17.7	TOP-HEAVY DEFINITION 

 If
the Top-Heavy Ratio for all plans in the Required Aggregation Group (RAG) exceeds 6/10, then all plans in the RAG are Top-Heavy unless there exists a Permissive Aggregation Group (PAG) for which the Top-Heavy Ratio does not exceed 6/10, in which
case no plan in the PAG is Top Heavy. 
  

	17.8	MINIMUM ALLOCATION 

  

	 	(a)	 Except as otherwise provided in paragraph (b) and (c) below, Company Contributions and forfeitures allocated on behalf of any Participant who
is not a Key Employee shall not be less than the lesser of 3% of such Participant’s compensation or in the case where the Corporation has no defined benefit plan 

  
 17.2

	 	 
that designates this Plan to satisfy Code Section 401, the highest rate of Corporation Contributions and forfeitures, as limited by Section 17.10, allocated on behalf of any Key
Employee for that year. The minimum allocation shall be made even though, under other Plan provisions, the Participant would not otherwise be entitled to receive an allocation or would have received a lesser allocation for the year because of:

  

	 	(1)	The Participant’s failure to complete 1,000 Hours of Service (or any equivalent provided in the Plan); or 

 

	 	(2)	The Participant’s failure to make mandatory employee contributions to the Plan; or 

 

	 	(3)	Compensation less than a stated amount.

 SECTION 18 
 SPECIAL RULES FOR EMPLOYEES IN PUERTO RICO 
  

	18.1	PURPOSE AND EFFECT 

 The
purpose of this Section 18 is to comply with the requirements of PR-Code Sections 1165(a) and (e). The provisions of this Section 18 shall be effective January 1, 2009, and shall only apply to those Eligible Employees of the
Corporation whose compensation is subject to Puerto Rico income tax (“Section 18 Eligible Employee”). In addition to complying with the applicable provisions of the Plan, Section 18 Eligible Employees must comply with the provisions
of this Section 18. In the event of a discrepancy or conflict between this Section 18 and the other provisions of the Plan, that affects a Section 18 Eligible Employee, the provisions of this Section 18 shall prevail. 

 

	18.2	TYPE OF PLAN 

 It is the
intent of the Corporation that the Plan be a stock bonus plan as defined in Article 1165-1(b)(1)(iii) of the PR-Code Regulations and that it include a qualified cash or deferred arrangement pursuant to PR-Code Section 1165(e). 

 

	18.3	LIMITATIONS ON SECTION 18 ELIGIBLE EMPLOYEE’S ELECTIVE DEFERRALS 

 Notwithstanding the provisions of Section 16, in no event shall a Section 18 Eligible Employee’s Elective Deferrals for any calendar year exceed the maximum amount permitted to be deferred
under PR-Code Section 1165(e)(7)(A). The maximum deferred amount contained in PR-Code Section 1165(e)(7)(A) shall be (a) $9,000 for the Plan Year beginning January 1, 2010, (b) $10,000 for Plan Years beginning
January 1, 2011 and 2012 and (c) $12,000 for Plan Years beginning on and after January 1, 2013, or as otherwise provided under the PR-Code. 
  

	18.4	HIGHLY COMPENSATED SECTION 18 EMPLOYEES 

 Any Section 18 Eligible Employee who, determined on the basis of Compensation (as that term is defined in Section 16.2(e)) for each Plan Year, has greater Compensation than two-thirds of all
other Section 18 Eligible Employees shall be considered a Highly Compensated Section 18 Eligible Employee. 
  

	18.5	ADDITIONAL LIMITATIONS ON SECTION 18 ELIGIBLE EMPLOYEE’S COMPENSATION REDIRECTION AMOUNTS 

For each Plan Year, in addition to satisfying the actual deferral percentage test of Code Section 401(k) and set forth in
Section 16, the Plan shall satisfy the average deferral percentage test of PR-Code Section 1165(e)(3) and the regulations promulgated thereunder. If for any Plan Year the average deferral percentage test of PR-Code Section 1165(e)(3)
is failed, excess contributions relating to Section 18 Eligible Employees shall not be distributed according to the provisions of Section 16.12. Instead, the Corporation 

  
 18.1

 
shall make a qualified non-elective contribution as defined in PR-Code Section 1165(e)(3)(E)(ii) to correct the failed test. The qualified non-elective contribution shall be allocated among
non-Highly Compensated Section 18 Eligible Employees in the manner prescribed by PR-Code Section 1165(e)(3) and the regulations thereunder. The Administrator may, at any time during the Plan Year, restrict the Elective Deferrals allowed to
a Highly Compensated Section 18 Eligible Employee if it determines that such restriction is necessary to assure the Plan’s compliance with the average deferral percentage test of PR-Code Section 1165(e)(3). 

 

	18.6	CATCH-UP CONTRIBUTIONS 

Provided he has attained age 50 before the close of the Plan Year, a Section 18 Eligible Employee shall be eligible to make catch-up
contributions in accordance with Section 2.6, and subject to the limitations of PR-Code Section 1165(e)(7)(C). Such catch-up contributions shall not be taken into account for purposes of the provisions of the Plan implementing the required
limitations of PR-Code Section 1165(e)(7(A). The Plan shall not be treated as failing to satisfy the provisions of the Plan implementing the requirements of PR-Code Sections 1165(e)(3)(A)(ii)(I) and (II) and 1165(e)(3)(B)(i) and (ii), as
applicable, by reason of the making of such catch-up contributions. 
  

	18.7	SAVINGS CONTRIBUTIONS 

Notwithstanding the provisions of Section 2.2, in no event shall a Section 18 Eligible Employee be permitted to make Savings
Contributions in excess of 10% of his Eligible Earnings. 
  

	18.8	ROLLOVER CONTRIBUTIONS 

Rollover Contributions as defined in Section 4.3 by a Section 18 Eligible Employee into the Plan may only be allowed if such
Rollover Contributions come from another plan qualified under both Code Section 401(a) and PR-Code Section 1165(a) and (e). 
  

	18.9	WITHDRAWALS ON ACCOUNT OF HARDSHIP 

 Withdrawals of Elective Deferrals, Rollover and Catch-Up Contributions by Section 18 Eligible Employees on account of Hardship described in Section 9.5 shall be allowed in accordance with the
deemed hardship standards under Article 1165-8 (d)(2) of the Regulations issued under the PR-Code and to the extent permitted under both Section 9.5 and such deemed hardship standards under Article 1165-8(d)(2) of the Regulations under the
PR-Code. A Section 18 Eligible Employee who makes a hardship withdrawal pursuant to this Section 18.9 shall not be permitted to make any Elective Deferral Contributions, Catch-Up Contributions or Savings Contributions until the end of the
12-month period commencing on the date such withdrawal was received by the Section 18 Eligible Employee. 
  

	18.10	ROTH ELECTIVE DEFERRALS 

Section 18 Eligible Employees are not permitted to make Roth Elective Deferrals described in Section 2.7. 

  
 18.2

	18.11	MATCHING CONTRIBUTIONS 

To the extent permissible under ERISA each matching contribution made by the Corporation for the benefit of a Section 18 Eligible
Employees is expressly conditioned on the deductibility of such contribution under PR-Code Section 1023(n) for the taxable year for which contributed. If the Puerto Rico Treasury Department disallows the deduction, or if the contribution was
made by mistake of fact, such contributions shall be returned to the Corporation within one year after the disallowance of the deduction (to the extent disallowed), or after the payment of the contribution, respectively. 

 

	18.12	ELIGIBLE ROLLOVER DISTRIBUTIONS 

 Notwithstanding the provisions of Section 11.5, a Section 18 Eligible Employee may, in addition to the rollover options set forth in Section 11.5, request at the time and manner prescribed
by the Administrator, to have the entire portion of a lump-sum distribution from the Plan paid directly to a Puerto Rico Eligible Retirement Plan (as defined below) in a direct rollover. For purposes of this paragraph, the term “Puerto Rico
Eligible Retirement Plan” means a qualified trust described in PR-Code Section 1165(a) and an individual retirement account or annuity described in PR-Code Sections 1169 (a) and (b), respectively, that accepts a Section 18
Eligible Employee’s eligible rollover distribution. 
  

	18.13	GOVERNING LAW

respect to Section 18 Eligible Employees and any Subsidiary or Affiliate engaged in trade or business in Puerto Rico, the Plan shall also be governed and construed according to the PR-Code, where such law is not in conflict with the applicable
federal laws. 
  

	18.14	USE OF TERMS 

 All terms
and provisions of the Plan shall apply to this Section 18, except that where the terms and provisions of the Plan and this Section 18 conflict, the terms and provisions of this Section 18 shall govern except to the extent that the

liability, or expense that is a result of his or her own willful misconduct. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s Articles
of Incorporation or Bylaws, conferred in a separate agreement with the Company, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless. 

3.03 Limitation on Vesting for Awards. Notwithstanding any provision of the Plan to the contrary, any stock-settled Award granted

 ARTICLE IV 
 SHARES 
 4.01. Number of Shares Issuable. The total number of shares
initially authorized to be issued under the Plan shall be 10,800,000 shares of Common Stock. No more than 5,400,000 shares of Common Stock may be issued under the Plan as Awards under Articles VII, VIII and IX. The foregoing share limits shall be
subject to adjustment in accordance with Section 11.07. If any Award under the Plan expires, or is terminated, canceled, surrendered or forfeited, in whole or in part, the unissued or forfeited shares of Common Stock underlying such Award shall
again be available for the grant of new Awards under the Plan. The shares to be offered under the Plan shall be authorized and unissued Common Stock, or issued Common Stock that shall have been reacquired by the Company and held as treasury stock.

 4.02. Share Counting. 
 (a) Options. Upon the exercise of any Option, the maximum number of shares of Common Stock issuable upon exercise of such Option shall be counted against the number of shares available for
future issuance under the Plan, regardless of the number of shares of Common Stock actually issued by the Company in connection with such exercise, and any shares of Common Stock withheld by the Company or actually or deemed delivered by the
Participant to cover the Purchase Price or any applicable withholding taxes in connection with such exercise shall not be deemed to increase the number of shares remaining available for future issuance under the Plan. 

(b) Stock Appreciation Rights. Upon the exercise of any Stock Appreciation Right, the maximum number of shares
of Common Stock subject to such Stock Appreciation Right (or portion thereof being exercised) shall reduce the number of shares of Common Stock available for future issuance under the Plan, regardless of the number of shares of Common Stock actually
issued by the Company in connection with such exercise, and any shares of Common Stock withheld by the Company or actually or deemed delivered by the Participant to cover any applicable withholding taxes in connection with such exercise shall not be
deemed to increase the number of shares remaining available for future issuance under the Plan. 

(c) Other Awards. In the case of Restricted Stock, Restricted Stock Units and other Common Stock-denominated
Awards that vest and are settled in shares of Common Stock, the number of shares of Common Stock actually earned and issued by the Company upon settlement of the Award plus the number shares of Common Stock withheld by the Company or actually or
deemed delivered by the Participant to cover any applicable withholding taxes in connection with such settlement, shall reduce the number of shares of Common Stock available for future issuance under the Plan. Restricted Stock Units and other Common
Stock-denominated Awards that are settled in cash, and any other Awards that are denominated and settled in cash, shall not reduce the number of shares of Common Stock available for future issuance under the Plan. 

(d) Deferrals. Any shares of Common Stock that would have been issued upon the settlement of an Award but for
the deferral of such Award in accordance with the PPG Industries, Inc. Deferred Compensation Plan (as amended from time to time, the “Deferred Compensation Plan”) or PPG Industries, Inc. Deferred Compensation Plan for Directors (as amended
from time to time, the “Directors’ Deferred Compensation Plan”), as applicable, shall reduce the number of shares available for future issuance under the Plan as of the date such Award would otherwise have been settled, but any Awards
or portions thereof payable in cash, whether at the election of the Participant or otherwise, that are deferred in accordance with the Deferred Compensation Plan or Directors’ Deferred Compensation Plan, as applicable, shall not reduce the
number of shares available for future issuance under the Plan. 

  
 7 

 (e) Substitute Awards and Shares Issuable under Acquired Company
Plans. Substitute Awards shall not be counted against or otherwise reduce the number of shares available for future issuance under the Plan. In addition, if a company acquired by the Company or any Subsidiary or with which the Company or any
Subsidiary combines has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as
adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to
such acquisition or combination) may be used for Awards under the Plan and shall not reduce the shares available for future issuance under the Plan. Awards using such available shares under acquired plans shall not be made after the date awards
could have been made under the terms of the acquired plan, absent the acquisition or combination, and shall only be made to individuals who were not eligible to participate in the Plan prior to such acquisition or combination. 

ARTICLE V 

PARTICIPATION 
 5.01. Eligible Participants. Participants in the Plan shall be such employees, directors and consultants of the Company and its Subsidiaries as the Committee, in its sole discretion, may designate
from time to time. The Committee’s designation of a Participant in any year shall not require the Committee to designate such person to receive Awards in any other year. The designation of a Participant to receive Awards under one portion of
the Plan does not require the Committee to include such Participant under other portions of the Plan. The Committee shall consider such factors as it deems pertinent in selecting Participants and in determining the type and amount of their
respective Awards. Subject to adjustment in accordance with Section 11.07, in any calendar year, no Participant shall be granted stock-based Awards in respect of more than 400,000 shares of Common Stock under Article VI or more than 200,000
shares of Common Stock under either Article VII, VIII or IX, or cash-based Awards for more than $6 million under Article X. 

ARTICLE VI 

OPTIONS AND STOCK APPRECIATION RIGHTS 
 6.01. Option Awards. 
 (a) Grant of Options. The
Committee may grant, to such Participants as the Committee may select, Options entitling the Participant to purchase shares of Common Stock from the Company in such number, at such Exercise Price, and on such terms and subject to such conditions,
not inconsistent with the terms of this Plan, as may be established by the Committee. The terms of any Option granted under this Plan shall be set forth in an Award Agreement. 

(b) Exercise Price of Options. The Exercise Price of each share of Common Stock which may be purchased upon
exercise of any Option granted under the Plan shall be determined by the Committee; provided, however, that in all cases the Exercise Price shall be equal to or greater than the Fair Market Value on the Date of Grant of the shares
of Common Stock subject to the Option. 
 (c) Designation of Options. All Options granted under the
Plan shall be designated as non-qualified stock options that are not intended to be governed by Section 422 of the Code. Such designation shall be set forth in the Award Agreement. 

  
 8 

 6.02. Stock Appreciation Rights. 

(a) Stock Appreciation Right Awards. The Committee is authorized to grant to any Participant one or more Stock
Appreciation Rights. Upon exercise of a Stock Appreciation Right with respect to a share of Common Stock, the Participant shall be entitled to receive an amount equal to the excess, if any, of (i) the Fair Market Value of a share of Common
Stock on the date of exercise over (ii) the Exercise Price of such Stock Appreciation Right established in the Award Agreement, which amount shall be payable as provided in Section 6.02(c). 

(b) Exercise Price. The Exercise Price of any Stock Appreciation Right granted under this Plan shall be
determined by the Committee; provided, however, that in all cases the Exercise Price shall be equal to or greater than the Fair Market Value on the Date of Grant of the shares of Common Stock subject to the Stock Appreciation Right.

 (c) Payment of Incremental Value. Any payment which may become due from the Company by reason of a
Participant’s exercise of a Stock Appreciation Right may be paid to the Participant as determined by the Committee (i) all in cash, (ii) all in Common Stock, or (iii) in any combination of cash and Common Stock. In the event that
all or a portion of the payment is made in Common Stock, the number of shares of Common Stock delivered in satisfaction of such payment shall be determined by dividing the amount of such payment or portion thereof by the Fair Market Value on the
Exercise Date. No fractional share of Common Stock shall be issued to make any payment in respect of Stock Appreciation Rights; if any fractional share would be issuable, the combination of cash and Common Stock payable to the Participant shall be
adjusted as directed by the Committee to avoid the issuance of any fractional share. 
 6.03. Terms of Options and Stock
Appreciation Rights. 
 (a) Conditions on Exercise. An Award Agreement with respect to Options
and/or Stock Appreciation Rights may contain such waiting periods, exercise dates and conditions or restrictions on exercise, whether based on performance standards, periods of service, retention by the Participant of ownership of specified shares
of Common Stock or other criteria, as may be determined by the Committee. 
 (b) Duration of Options and
Stock Appreciation Rights. Options and Stock Appreciation Rights shall terminate upon the first to occur of the following events: 
 (i) Expiration of the Option or Stock Appreciation Right as provided in the Award Agreement; or 
 (ii) Termination of the Award in the event of a Participant’s Termination of Service as provided in the Award Agreement; or 

(iii) Ten years from the Date of Grant. 

(c) Extension of Exercise Time. The Committee, in its sole discretion and subject to compliance with
Section 409A of the Code, shall have the right (but shall not be obligated), exercisable on or at any time after the Date of Grant, to extend the exercise period of an Option or Stock Appreciation Right beyond the termination or expiration of
the Option or Stock Appreciation Right under the terms of the Award Agreement; provided, in no event shall the exercise period be extended beyond the date set forth in Section 6.03(b)(iii). 

(d) Rights as a Shareholder. A Participant shall have no rights as a shareholder with respect to Common Stock
covered by any Options or Stock Appreciation Rights until such Participant shall have become the owner of record of any such shares, and no adjustment shall be made for dividends in cash or other property or distributions or other rights with
respect to any such Common Stock for which the record date is prior to the date on which such Participant shall have become the owner of record of any such shares; provided, however, that Participants are entitled to share adjustments to
reflect capital changes under Section 11.07. 

  
 9 

 6.04. Exercise Procedures. Each Option and Stock Appreciation Right granted under
the Plan shall be exercised prior to the close of business on the expiration date of the Option or Stock Appreciation Right by such method as provided in the Award Agreement or such other method as the Committee may establish or approve from time to
time. The Exercise Price of shares purchased upon exercise of an Option granted under the Plan shall be paid by the Participant in cash or by any other method approved by the Committee or as otherwise set forth in the applicable Award Agreement.

 6.05. Change in Control. Unless otherwise provided by the Committee in the applicable Award Agreement, in the event of
a Participant’s Termination of Service by the Company or a Subsidiary (including a successor) without Cause in connection with or within two years following the date of a Change in Control, all Options and Stock Appreciation Rights granted to
such Participant and outstanding on the date of such Termination of Service shall become immediately and fully exercisable. The provisions of this Section 6.05 shall not be applicable to any Options or Stock Appreciation Rights granted to a
Participant if any Change in Control results from such Participant’s beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of Common Stock or Company Voting Securities. 

ARTICLE VII 
 RESTRICTED STOCK AND RESTRICTED STOCK UNITS 
 7.01 Award of
Restricted Stock and Restricted Stock Units. The Committee may grant to any Participant an Award of Restricted Stock consisting of a specified number of shares of Common Stock issued to the Participant subject to such terms, conditions and
forfeiture and transfer restrictions, whether based on performance standards, periods of service, retention by the Participant of ownership of specified shares of Common Stock or other criteria, as the Committee shall establish. The Committee may
also grant Restricted Stock Units representing the right to receive shares of Common Stock in the future subject to such terms, conditions and restrictions, whether based on performance standards, periods of service, retention by the Participant of
ownership of specified shares of Common Stock or other criteria, as the Committee shall establish. With respect to performance-based Awards of Restricted Stock or Restricted Stock Units intended to qualify as “performance-based”
compensation for purposes of Section 162(m) of the Code, performance targets will consist of specified levels of one or more of the Performance Goals. The terms of any Restricted Stock and Restricted Stock Unit Awards granted under this Plan
shall be set forth in an Award Agreement which shall contain provisions determined by the Committee and not inconsistent with this Plan. 
 7.02 Restricted Stock. 
 (a) Issuance of
Restricted Stock. As soon as practicable after the Date of Grant of an Award of Restricted Stock by the Committee, the Company shall cause to be transferred on the books of the Company shares of Common Stock, registered on behalf of the
Participant, evidencing the Restricted Stock covered by the Award. All shares of Common Stock covered by Awards under this Article VII shall be subject to the restrictions, terms and conditions contained in the Plan and the applicable Award
Agreement in respect of any such Awards. Until the lapse or release of all restrictions applicable to an Award of Restricted Stock, any share certificates representing such Restricted Stock may be held in custody by the Company, its designee, or, if
the certificates bear a restrictive legend, by the Participant. Upon the lapse or release of all restrictions with respect to an Award as described in Section 7.02(d), one or more share certificates, registered in the name of the Participant,
for an appropriate number of shares as provided in Section 7.02(d), free of any restrictions set forth in the Plan and the related Award Agreement shall be delivered to the Participant. 

  
 10 

 (b) Shareholder Rights. Beginning on the Date of Grant of a
Restricted Stock Award, and except as otherwise provided in the applicable Award Agreement, the Participant shall become a shareholder of the Company with respect to all shares subject to the Award Agreement and shall have all of the rights of a
shareholder, including, but not limited to, the right to vote such shares and the right to receive dividends; provided, however, that any shares of Common Stock distributed as a dividend or otherwise with respect to any Restricted
Stock as to which the restrictions have not yet lapsed, shall be subject to the same restrictions as such Restricted Stock and held or restricted as provided in Section 7.02(a). 

(c) Restriction on Transferability. Restricted Stock may not be assigned or transferred (other than by will or
the laws of descent and distribution or to an inter vivos trust with respect to which the Participant is treated as the owner under Sections 671 through 677 of the Code), pledged or sold prior to the lapse of the restrictions applicable
thereto. 
 (d) Delivery of Shares Upon Vesting. Upon expiration or earlier termination of the
forfeiture period without a forfeiture and the satisfaction of or release from any other conditions prescribed by the Committee, or at such earlier time as provided under the provisions of Section 3.03 or Section 7.04, the restrictions
applicable to the Restricted Stock shall lapse. As promptly as administratively feasible thereafter, subject to the requirements of Section 11.05, the Company shall deliver to the Participant or, in case of the Participant’s death, to the
Participant’s Beneficiary, one or more share certificates for the appropriate number of shares of Common Stock, free of all such restrictions, except for any restrictions that may be imposed by law. 

(e) Forfeiture of Restricted Stock. Subject to Sections 3.03 and 7.04, Restricted Stock shall be forfeited and
returned to the Company and all rights of the Participant with respect to such Restricted Stock shall terminate unless the Participant continues in the service of the Company or a Subsidiary until the expiration of the forfeiture period for such
Restricted Stock and satisfies any and all other conditions set forth in the Award Agreement. Subject to Section 3.03, the Committee shall determine the forfeiture period (which may, but need not, lapse in installments) and any other terms and
conditions applicable with respect to any Restricted Stock Award. 
 7.03 Restricted Stock Units. 

(a) Settlement of Restricted Stock Units. Payments shall be made to Participants with respect to their
Restricted Stock Units as soon as practicable after the Committee has determined that the terms and conditions applicable to such Award have been satisfied or at a later date if distribution has been deferred. Payments to Participants with respect
to Restricted Stock Units shall be made in the form of Common Stock, or cash or a combination of both, as the Committee may determine. The amount of any cash to be paid in lieu of Common Stock shall be determined on the basis of the Fair Market
Value of the Common Stock on the date any such payment is processed. As to shares of Common Stock which constitute all or any part of such payment, the Committee may impose such restrictions concerning their transferability and/or their forfeiture
as may be provided in the applicable Award Agreement or as the Committee may otherwise determine, provided such determination is made on or before the date certificates for such shares are first delivered to the applicable Participant. 

(b) Shareholder Rights. Until the lapse or release of all restrictions applicable to an Award of Restricted
Stock Units, no shares of Common Stock shall be issued in respect of such Awards and no Participant shall have any rights as a shareholder of the Company with respect to the shares of Common Stock covered by such Award of Restricted Stock Units.

 (c) Dividend Equivalents. For any Restricted Stock Unit granted under the Plan, the Committee
shall have the discretion, upon the Date of Grant or thereafter, to establish a Dividend Equivalent Account with respect to the Restricted Stock Unit, in accordance with Section 11.08. 

  
 11 

 (d) Deferral of Payment. If approved by the Committee and set
forth in the applicable Award Agreement, a Participant may elect to defer the amount payable with respect to the Participant’s Restricted Stock Units in accordance with the Deferred Compensation Plan or Directors’ Deferred Compensation
Plan, as applicable. 
 7.04 Change in Control. Unless otherwise provided by the Committee in the applicable Award
Agreement, in the event of a Participant’s Termination of Service by the Company or a Subsidiary (including a successor) without Cause in connection with or within two years following the date of a Change in Control, all restrictions applicable
to Restricted Stock and Restricted Stock Unit Awards granted to such Participant and outstanding as of the date of such Termination of Service shall terminate fully and the Participant shall immediately have the right to the delivery in accordance
with Section 7.02(d) of a share certificate or certificates evidencing a number of shares of Common Stock equal to the full number of shares subject to each such Award (in the case of Restricted Stock) or payment in accordance with
Section 7.03(a) of a number of shares of Common Stock determined by the Committee, in its discretion, but, in the case of a performance-based or other contingent Award, in no event less than the number of shares payable at the
“target” level for each such Award (in the case of Restricted Stock Units). 
 ARTICLE VIII 

PERFORMANCE AWARDS 
 8.01. Performance Awards. 
 (a) Award Periods and
Calculations of Potential Incentive Amounts. The Committee may grant Performance Awards to Participants. A Performance Award shall consist of the right to receive a payment (measured by the Fair Market Value of a specified number of shares of
Common Stock, increases in such Fair Market Value during the Award Period and/or a fixed cash amount) contingent upon the extent to which certain predetermined performance targets have been met during an Award Period. The Award Period shall be two
or more fiscal or calendar years as determined by the Committee. The Committee, in its discretion and under such terms as it deems appropriate, may permit Participants to receive Performance Awards after an Award Period has commenced. 

(b) Performance Targets. The performance targets may include such goals related to the performance of the
Company or, where relevant, any one or more of its Subsidiaries or divisions and/or the performance of a Participant as may be established by the Committee in its discretion. In the case of Performance Awards that are intended to qualify as
“performance-based” compensation for purposes of Section 162(m) of the Code, the targets will be limited to specified levels of one or more of the Performance Goals. The performance targets established by the Committee may vary for
different Award Periods and need not be the same for each Participant receiving a Performance Award in an Award Period. Except to the extent inconsistent with the performance-based compensation exception under Section 162(m) of the Code, in the
case of Performance Awards granted to employees to whom such section is applicable, the Committee, in its discretion, but only under extraordinary circumstances as determined by the Committee, may change any prior determination of performance
targets for any Award Period at any time prior to the final determination of the Award when events or transactions occur to cause the performance targets to be an inappropriate measure of achievement. 

(c) Earning Performance Awards. The Committee, at or as soon as practicable after the Date of Grant, shall
prescribe a formula to determine the percentage of the Performance Award to be earned based upon the degree of attainment of the applicable performance targets. 

  
 12 

 (d) Payment of Earned Performance Awards. Subject to the
requirements of Section 11.05, payments of earned Performance Awards shall be made in cash or Common Stock, or a combination of cash and Common Stock, in the discretion of the Committee. The Committee, in its sole discretion, may define, and
set forth in the applicable Award Agreement, such terms and conditions with respect to the payment of earned Performance Awards as it may deem desirable. 
 (e) Dividend Equivalents. For any Performance Award granted under the Plan, the Committee shall have the discretion, upon the Date of Grant or thereafter, to establish a Dividend Equivalent
Account with respect to the Performance Award, in accordance with Section 11.08. 
 (f) Deferral of
Payment. If approved by the Committee and set forth in the applicable Award Agreement, a Participant may elect to defer the amount payable with respect to the Participant’s Performance Award in accordance with the Deferred Compensation Plan
or Directors’ Deferred Compensation Plan, as applicable. 
 8.02. Termination of Service. Subject to
Section 8.03, in the event of a Participant’s Termination of Service during an Award Period, the Participant’s Performance Awards shall be forfeited except as may otherwise be provided in the applicable Award Agreement. 

8.03. Change in Control. Unless otherwise provided by the Committee in the applicable Award Agreement, in the event of a
Participant’s Termination of Service by the Company or a Subsidiary (including a successor) without Cause in connection with or within two years following the date of a Change in Control, all Performance Awards for all Award Periods granted to
such Participant and outstanding as of the date of such Termination of Service shall immediately become fully vested and payable to the Participant. The Participant shall be paid in accordance with Section 8.01(d), within 30 days after such
Change in Control, a number of shares determined by the Committee, in its discretion, but in no event less than the number of shares payable at the “target” level. 
 ARTICLE IX 
 OTHER STOCK-BASED AWARDS 

9.01. Grant of Other Stock-Based Awards. Other stock-based awards, consisting of Substitute Awards, stock purchase rights, Awards
of Common Stock, or Awards valued in whole or in part by reference to, or otherwise based on, Common Stock, may be granted either alone or in addition to or in conjunction with other Awards under the Plan. Subject to the provisions of the Plan, the
Committee shall have sole and complete authority and discretion to determine the persons to whom and the time or times at which such Awards shall be made, the number of shares of Common Stock to be granted pursuant to such Awards, and all other
conditions of the Awards. Any such Award may be confirmed by an Award Agreement executed by the Committee and the Participant, which Award Agreement shall contain such provisions as the Committee determines to be necessary or appropriate to carry
out the intent of this Plan with respect to such Award. 
 9.02. Terms of Other Stock-Based Awards. In addition to the
terms and conditions specified in the Award Agreement, Awards made pursuant to this Article IX shall be subject to the following: 
 (a) Any Common Stock subject to Awards made under this Article IX may not be sold, assigned, transferred, pledged or otherwise encumbered prior to the date on which the shares are issued, or, if later,
the date on which any applicable restriction, performance or deferral period lapses; 
 (b) For any such Award,
the Committee shall have the discretion, upon the Date of Grant or thereafter, to establish a related Dividend Equivalent Account, in accordance with Section 11.08; 

  
 13 

 (c) Subject to Section 3.03, any Award Agreement with respect to any
Award shall contain provisions dealing with the disposition of such Award in the event of a Termination of Service prior to the exercise, realization or payment of such Award, with such provisions to take account of the specific nature and purpose
of the Award; and 
 (d) If approved by the Committee and set forth in any applicable Award Agreement, a
Participant may elect to defer the amount payable to the Participant Award under this Article IX in accordance with the Deferred Compensation Plan or Directors’ Deferred Compensation Plan, as applicable. 

ARTICLE X 

SHORT-TERM CASH INCENTIVE AWARDS 
 10.01. Eligibility. Executive officers of the Company who are from time to time determined by the Committee to be “covered employees” for purposes of Section 162(m) of the Code will
be eligible to receive short-term cash incentive awards under this Article X. 
 10.02. Awards. 

(a) Performance Targets. The Committee shall, for each Award under this Article X, establish objective
performance targets based on specified levels of one or more of the Performance Goals. Such performance targets shall be established by the Committee on a timely basis to ensure that the targets are considered “preestablished” for purposes
of Section 162(m) of the Code. 
 (b) Amounts of Awards. In conjunction with the establishment
of performance targets for a fiscal year, the Committee shall adopt an objective formula (on the basis of percentages of Participants’ salaries, shares in a bonus pool or otherwise) for computing the respective amounts payable under the Plan to
Participants if and to the extent that the performance targets are attained. Such formula shall comply with the requirements applicable to performance-based compensation plans under Section 162(m) of the Code and, to the extent based on
percentages of a bonus pool, such percentages shall not exceed 100% in the aggregate. 
 (c) Payment of
Awards. Awards will be payable to Participants in cash each year upon prior written certification by the Committee of attainment of the specified performance targets for the preceding fiscal year; provided, however, that the
Committee, in its discretion, may determine that all or any part of an Award under this Article X shall be converted into and paid in the form of unrestricted shares of Common Stock, using for such purpose such conversion methodology as the
Committee shall approve. 
 (d) Negative Discretion. Notwithstanding the attainment by the Company of
the specified performance targets, the Committee shall have the discretion, which need not be exercised uniformly among the Participants, to reduce or eliminate the Award that would be otherwise paid. 

(e) Guidelines. The Committee may adopt from time to time written policies for its implementation of this
Article X. Such guidelines shall reflect the intention of the Company that all payments hereunder qualify as performance-based compensation under Section 162(m) of the Code. 

(f) Non-Exclusive Arrangement. The adoption and operation of this Article X shall not preclude the Board or
the Committee from approving other short-term incentive compensation arrangements for the benefit of individuals who are Participants hereunder as the Board or Committee, as the case may be, deems appropriate and in the best interests of the
Company. 

  
 14 

 (g) Deferral of Payment. If approved by the Committee and set
forth in the applicable Award Agreement, a Participant may elect to defer the amount payable to the Participant in respect of an Award under this Article X in accordance with the Deferred Compensation Plan. 

ARTICLE XI 

TERMS APPLICABLE GENERALLY TO AWARDS 
 GRANTED UNDER THE PLAN 
 11.01. Plan Provisions Control Award Terms.
The terms of the Plan shall govern all Awards granted under the Plan, and in no event shall the Committee have the power to grant any Award under the Plan which is contrary to any of the provisions of the Plan. In the event any provision of any
Award granted under the Plan shall conflict with any term in the Plan as constituted on the Date of Grant of such Award, the term in the Plan as constituted on the Date of Grant of such Award shall control. 

11.02. Award Agreement. No person shall have any rights under any Award granted under the Plan unless and until the Company and
the Participant to whom such Award shall have been granted shall have executed and delivered an Award Agreement or the Participant to whom such Award shall have been granted shall have received a written or electronic Award acknowledgement or other
notification authorized by the Committee and expressly granting the Award to such Participant and containing such provisions setting forth the terms of the Award as the Committee shall determine. 

11.03. Modification of Award After Grant. Except as provided in Section 11.07, no Award granted under the Plan to a
Participant may be modified (unless such modification does not materially decrease the value of the Award) after the Date of Grant except by the express written agreement of the Company and the Participant; provided, however, that
any such change (a) shall not be inconsistent with the terms of the Plan and (b) shall be approved by the Committee. 

11.04. Limitation on Transfer. Except as provided in Section 7.02(c) in the case of Restricted Stock, a Participant’s
rights and interest under the Plan may not be assigned or transferred other than by will or the laws of descent and distribution, and during the lifetime of a Participant, only the Participant personally (or the Participant’s personal
representative) may exercise rights under the Plan. The Participant’s Beneficiary may exercise the Participant’s rights to the extent they are exercisable under the Plan following the death of the Participant. Notwithstanding the
foregoing, the Committee may grant Options that are transferable, without payment of consideration by the Participant, to immediate family members of the Participant or to trusts or partnerships for such family members, and the Committee may also
amend outstanding Options to provide for such transferability. 
 11.05. Taxes. Subject to compliance with all applicable
legal requirements, the Company shall be entitled to withhold (or secure payment from the Participant in lieu of withholding) the amount of any withholding or other tax required by law to be withheld or paid by the Company with respect to any amount
payable and/or shares issuable under such Participant’s Award, and the Company may defer payment or issuance of the cash or shares upon exercise or settlement of an Award unless indemnified to its satisfaction against any liability for any such
tax. The amount of such withholding or tax payment shall be determined by the Company and, in the Company’s sole discretion, such withholding obligation shall be satisfied by (i) having the Company withhold from such Award that number of
shares of Common Stock, rounded down to the next whole share, whose aggregate Fair Market Value on the date such shares are withheld equals the amount of withholding taxes due, (ii) by direct payment by the Participant to the Company in cash of
the amount of any taxes required to be withheld with respect to such Award or (iii) by a combination of (i) and (ii). 

  
 15 

 11.06. Surrender of Awards. Any Award granted under the Plan may be surrendered to
the Company for cancellation on such terms as agreed upon by the Committee and the Participant. With the consent of the Participant, the Committee may substitute a new Award under this Plan in connection with the surrender by the Participant of an
equity compensation award previously granted under this Plan or any other plan sponsored by the Company; provided, however, that no such substitution shall be permitted without the approval of the Company’s shareholders if such
approval is required by the rules of any applicable stock exchange. 
 11.07. Adjustments to Reflect Capital Changes.

 (a) Recapitalization. In the event of any “equity restructuring” (within the meaning of
FASB ASC Topic 718, Compensation—Stock Compensation) that causes the per share value of shares of Common Stock to change, such as a stock dividend, stock split, spinoff, rights offering or recapitalization through an extraordinary dividend, the
Committee shall make such adjustments as it deems equitable and appropriate to (i) the aggregate number and kind of shares or other securities issued or reserved for issuance under the Plan, (ii) the number and kind of shares or other
securities subject to outstanding Awards, (iii) the Exercise Price of outstanding Options and Stock Appreciation Rights, and (iv) any maximum limitations prescribed by the Plan with respect to certain types of Awards or the grants to
individuals of certain types of Awards. In the event of any other change in corporate capitalization, including a merger, consolidation, reorganization, or partial or complete liquidation of the Company, such equitable adjustments described in the
foregoing sentence may be made as determined to be appropriate and equitable by the Committee (or, if the Company is not the surviving corporation in any such transaction, the board of directors of the surviving corporation) to prevent dilution or
enlargement of the rights of Participants. No adjustment shall be made pursuant to this Section 11.07(a) in connection with the conversion of any convertible securities of the Company, or in a manner that would cause an Award to be subject to
adverse tax consequences under Section 409A of the Code. The Committee shall have the power and sole discretion to determine the amount of the adjustment to be made in each case under this Section 11.07(a). 

(b) Merger. In the event of a Merger in which the Company is not the surviving corporation, the surviving,
continuing, successor, or purchasing corporation, as the case may be (the “Acquiring Corporation”), shall, at least ten business days prior to the consummation of such Merger, either (i) agree with the Company in writing to assume the
Company’s rights and obligations in respect of Awards outstanding immediately prior to the consummation of such Merger or (ii) grant substantially equivalent awards in respect of the Acquiring Corporation’s voting common stock for
such outstanding Awards on terms and conditions substantially similar to and no less favorable to each Participant than the terms and conditions of such outstanding Awards. In the event the Acquiring Corporation fails to comply with this
Section 11.07(b), the Board shall provide that any unexercisable and/or unvested portion of the outstanding Awards shall be immediately exercisable and vested as of a date prior to such Merger, as the Board so determines. The exercise and/or
vesting of any Award that was permissible solely by reason of this Section 11.07(b) may be conditioned upon the consummation of the Merger in the Board’s discretion. Any Options which are neither assumed by the Acquiring Corporation nor
exercised as of the date of the Merger shall terminate effective as of the effective date of the Merger. 

(c) Options to Purchase Shares or Stock of Acquired Companies. After any Merger in which the Company or a
Subsidiary shall be a surviving corporation, the Committee may grant substituted options under the provisions of the Plan, and in accordance with applicable law, replacing old options granted under a plan of another party to the Merger whose shares
or stock subject to the old options may no longer be issued following the Merger. The foregoing adjustments and manner of application of the foregoing provisions shall be determined by the Committee in its sole discretion. Any such adjustments may
provide for the elimination of any fractional shares which might otherwise become subject to any Options. 

  
 16 

 11.08. Dividend Equivalents. For any Award granted under Sections VII, VIII or IX of
the Plan, the Committee shall have the discretion, upon the Date of Grant or thereafter, to establish a Dividend Equivalent Account with respect to the Award, and the applicable Award Agreement or an amendment thereto shall confirm such
establishment. If a Dividend Equivalent Account is established, the following terms shall apply: 

(a) Terms and Conditions. Dividend Equivalent Accounts shall be subject to such terms and conditions as the
Committee shall determine and as shall be set forth in the applicable Award Agreement. Such terms and conditions may include, without limitation, for the Participant’s Account to be credited as of the record date of each cash dividend on the
Common Stock with an amount equal to the cash dividends which would be paid with respect to the number of shares of Common Stock then covered by the related Award if such shares of Common Stock had been owned of record by the Participant on such
record date and for such dividend credits to be transferred to and administered in accordance with the Deferred Compensation Plan or Directors’ Deferred Compensation Plan, as applicable. 

(b) Unfunded Obligation. Dividend Equivalent Accounts shall be established and maintained only on the books
and records of the Company and no assets or funds of the Company shall be set aside, placed in trust, removed from the claims of the Company’s general creditors, or otherwise made available until such amounts are actually payable as provided
hereunder. 
 (c) Performance Award Limitations. Notwithstanding any other provision of this Section 11.08
or the Plan to the contrary, amounts credited to a Participant’s Dividend Equivalent Account with respect to any unvested portions of an Award whose vesting is subject to the achievement of specified Performance Goals or other performance-based
criteria shall be subject to the same vesting or forfeiture restrictions as the shares or units underlying the Award to which such dividend equivalents relate. 
 11.09 No Right to Continued Service. No person shall have any claim of right to be granted an Award under this Plan. Neither the Plan nor any action taken hereunder shall be construed as
giving any Participant any right to be retained in the service of the Company or any of its Subsidiaries. 
 11.10. Awards
Not Includable for Benefit Purposes. Payments received by a Participant pursuant to the provisions of the Plan shall not be included in the determination of benefits under any pension, group insurance or other benefit plan applicable to the
Participant which is maintained by the Company or any of its Subsidiaries, except as may be provided under the terms of such plans or determined by the Board. 
 11.11. Governing Law. All determinations made and actions taken pursuant to the Plan shall be governed by the laws of the Commonwealth of Pennsylvania, other than the conflict of laws provisions
thereof. 
 11.12. No Strict Construction. No rule of strict construction shall be implied against the Company, the
Committee, or any other person in the interpretation of any of the terms of the Plan, any Award granted under the Plan or any rule or procedure established by the Committee. 
 11.13. Compliance with Rule 16b-3 and Section 409A. It is intended that, unless the Committee determines otherwise, Awards under the Plan be eligible for exemption under Rule 16b-3. The Board
is authorized to amend the Plan and to make any such modifications to Award Agreements to comply with Rule 16b-3, as it may be amended from time to time, and to make any other such amendments or modifications as it deems necessary or appropriate to
better accomplish the purposes of the Plan in light of any amendments made to Rule 16b-3. It is further intended that Awards under the Plan shall either be exempt from or compliant with Section 409A of the Code and Awards granted under the Plan

shall be interpreted accordingly. The Board is authorized to amend the Plan and to make any such modifications to Award Agreements as the Board may deem necessary or appropriate to secure
exemption from or compliance with Section 409A of the Code. 
 11.14. Captions. The captions (i.e., all Section
headings) used in the Plan are for convenience only, do not constitute a part of the Plan, and shall not be deemed to limit, characterize or affect in any way any provisions of the Plan, and all provisions of the Plan shall be construed as if no
captions have been used in the Plan. 
 11.15. Severability. Whenever possible, each provision in the Plan and every
Award at any time granted under the Plan shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of the Plan or any Award at any time granted under the Plan shall be held to be prohibited by or
invalid under applicable law, then (a) such provision shall be deemed amended to accomplish the objectives of the provision as originally written to the fullest extent permitted by law and (b) all other provisions of the Plan and every
other Award at any time granted under the Plan shall remain in full force and effect. 
 11.16. Amendment and
Termination. 
 (a) Amendment. The Board or the Committee shall have complete power and authority
to amend the Plan at any time; provided, however, that neither the Board nor the Committee shall, without the requisite approval of shareholders of the Company, make any amendment which requires shareholder approval under the Code or under
any other applicable law or rule of any stock exchange which lists Common Stock or Company Voting Securities. No termination or amendment of the Plan may, without the consent of the Participant to whom any Award shall theretofore have been granted
under the Plan, adversely affect the right of such individual under such Award. Notwithstanding any provision herein to the contrary, the repricing of Options or Stock Appreciation Rights is prohibited without prior approval of the Company’s
shareholders. For this purpose, a “repricing” means any of the following (or any other action that has the same effect as any of the following): (i) changing the terms of an Option or Stock Appreciation Right to lower its Exercise
Price; (ii) any other action that is treated as a “repricing” under generally accepted accounting principles; and (iii) repurchasing for cash or canceling an Option or Stock Appreciation Right at a time when its Exercise Price is
greater than the Fair Market Value of the underlying Common Stock in exchange or substitution for another Award, unless the exchange or substitution occurs in connection with a change in capitalization or similar change under Section 11.07
above. Such exchange or substitution as described in clause (iii) of the preceding sentence would be considered a “repricing” regardless of whether it is treated as a “repricing” under generally accepted accounting
principles and regardless of whether it is voluntary on the part of the Participant. By way of clarification and not limitation, except in connection with a corporate transaction involving the Company (including, without limitation, any stock
dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination or exchange of shares), the terms of outstanding Awards may not be amended to reduce the Exercise Price of
outstanding Options or Stock Appreciation Rights or cancel outstanding Options or Stock Appreciation Rights in exchange for cash, other Awards or Options or Stock Appreciation Rights with an Exercise Price that is less than the Exercise Price of the
original Options or Stock Appreciation Rights without shareholder approval. 
 (b) Termination. The
Board shall have the right and the power to terminate the Plan at any time. No Award shall be granted under the Plan after the termination of the Plan, but the termination of the Plan shall not have any other effect and any Award outstanding at the
time of the termination of the Plan may be exercised after termination of the Plan at any time prior to the expiration date of such Award to the same extent such Award would have been exercisable had the Plan not terminated.

 11.17. Foreign Qualified Awards. Awards under the Plan may be granted to such
employees, directors and consultants of the Company and its Subsidiaries residing in foreign jurisdictions as the Committee in its sole discretion may determine from time to time. The Committee may adopt such supplements to the Plan as may be
necessary or appropriate to comply with the applicable laws of such foreign jurisdictions and to afford Participants favorable treatment under such laws; provided, however, that no Award shall be granted under any such supplement with terms
or conditions inconsistent with the provision set forth in the Plan. 
 11.18. Adjustment of Performance Goals and Targets.
Notwithstanding any provision of the Plan to the contrary, the Committee shall have the authority to adjust any Performance Goal, performance target or other performance-based criteria established with respect to any Award under the Plan if
circumstances occur (including, but not limited to, unusual or nonrecurring events, changes in tax laws or accounting principles or practices or changed business or economic conditions) that cause any such Performance Goal, performance target or
performance-based criteria to be inappropriate in the judgment of the Committee; provided, that with respect to any Award that is intended to qualify for the “performance-based compensation” exception under Section 162(m) of
the Code and the regulations thereunder, any adjustment by the Committee shall be consistent with the requirements of Section 162(m) and the regulations thereunder. 
 11.19. Legality of Issuance. Notwithstanding any provision of this Plan or any applicable Award Agreement to the contrary, the Committee shall have the sole discretion to impose such conditions,
restrictions and limitations (including suspending exercises of Options or Stock Appreciation Rights and the tolling of any applicable exercise period during such suspension) on the issuance of Common Stock with respect to any Award unless and until
the Committee determines that such issuance complies with (i) any applicable registration requirements under the Securities Act (or the Committee has determined that an exemption therefrom is available), (ii) any applicable listing
requirement of any stock exchange on which the Common Stock is listed, (iii) any applicable Company policy or administrative rules, and (iv) any other applicable provision of state, federal or foreign law, including foreign securities laws
where applicable. 
 11.20. Restrictions on Transfer. Regardless of whether the offering and sale of Common Stock under
the Plan have been registered under the Securities Act or have been registered or qualified under the securities laws of any state, the Company may impose restrictions upon the sale, pledge, or other transfer of such Common Stock (including the
placement of appropriate legends on stock certificates) if, in the judgment of the Company and its counsel, such restrictions are necessary or desirable to achieve compliance with the provisions of the Securities Act, the securities laws of any
state, the United States or any other applicable foreign law. 
 11.21 Recovery of Compensation in Connection with Financial
Restatement. Notwithstanding any other provision of this Plan or any applicable Award Agreement to the contrary, if the Board determines that the Company is required to restate its financial statements due to material noncompliance with any
financial reporting requirement under the law, whether such noncompliance is the result of misconduct or other circumstances, a Participant shall be required to reimburse the Company for any amounts earned or payable with respect to an Award to the
extent required by and otherwise in accordance with applicable law and any Company policies. 
 11.22 Book Entry.
Notwithstanding any other provision of this Plan to the contrary, the Company may elect to satisfy any requirement under this Plan for the delivery of stock certificates through the use of book-entry.
