 62008 Equity Incentive Plan

 Exhibit 10.1 
 CALGON CARBON CORPORATION 
 2008 EQUITY INCENTIVE PLAN 
 SECTION 1 
 Purpose;
Definitions 
 1.1 Purpose. The purposes of the 2008 Equity Incentive Plan (the “Plan”) are to encourage eligible
employees of and service providers to Calgon Carbon Corporation (the “Corporation”) and its Subsidiaries, and non-employee directors of the Corporation, to increase their efforts to make the Corporation and each Subsidiary more successful,
to provide an additional inducement for such persons to remain with the Corporation or a Subsidiary, to reward such persons by providing an opportunity to acquire shares of Common Stock on favorable terms, to provide a means through which the
Corporation may attract able persons to the Corporation or one of its Subsidiaries, and to align their interests with those of the shareholders of the Corporation. 
 1.2 Certain Definitions. In addition to terms defined herein in the first place where they are used, the following terms are defined as set forth below: 
 (a) “Award” means a stock option, a stock appreciation right, restricted stock, restricted stock units, performance units or
other stock-based award granted under the Plan. 
 (b) “Base Price” shall have the meaning set forth in
Section 5.3. 
 (c) “Board” means the Corporation’s Board of Directors. 
 (d) “Code” means the Internal Revenue Code of 1986, as amended from time to time, together with rules, regulations and
interpretations promulgated thereunder. References to particular sections of the Code shall include any successor provisions. 
 (e) “Committee” means, (a) with respect to Participants who are employees and other service providers, the Compensation Committee or such other committee of the Board as may be designated by the Board to administer the

 
Plan, as referred to in Section 2.1 hereof, consisting of at least two members of the Board; provided, however, that any member of the
Committee participating in the taking of any action under the Plan must qualify as (1) an “outside director” as then defined under Section 162(m) of the Code or any successor provision, (2) a “non-employee
director” as then defined under Rule 16b-3 or any successor rule and (3) an “independent” director under the rules of the New York Stock Exchange or any other principal stock exchange on which the Corporation may in the future be
listed, or (b) with respect to Participants who are non-employee directors, the Board or its designee, including the Corporate Governance Committee. 
 (f) “Common Stock” shall mean the Common Stock, par value $.01 per share, of the Corporation. 
 (g) “Covered Employees” shall have the meaning set forth in Section 2.1. 
 (h)
“Exchange Act” means the Securities Exchange Act of 1934, as amended. 
 (i) “Fair Market Value” with
respect to a share of the Common Stock shall mean the mean between the following prices, as applicable, for the date as of which Fair Market Value is to be determined as quoted in The Wall Street Journal (or in such other
reliable publication as the Committee, in its sole discretion, may determine to rely upon): (i) if the Common Stock is listed on the New York Stock Exchange, the highest and lowest sales prices per share of the Common Stock as quoted in the
NYSE-Composite Transactions listing for such date, (ii) if the Common Stock is not listed on such exchange, the highest and lowest sales prices per share of Common Stock for such date on (or on any composite index including) the principal
United States of America securities exchange registered under the Exchange Act on which the Common Stock is listed or (iii) if the Common Stock is not listed on any such exchange, the highest and lowest sales prices per share of the Common
Stock for such date on the National Association of Securities Dealers Automated Quotations System or any successor system then in use (“NASDAQ”). If there are no such sale price quotations for the date as of which Fair Market Value is to
be determined but there are such sale 

  

 -2- 

 
price quotations within a reasonable period both before and after such date, then Fair Market Value shall be determined by taking a weighted average of the
means between the highest and lowest sales prices per share of the Common Stock as so quoted on the nearest date before and the nearest date after the date as of which Fair Market Value is to be determined. The average should be weighted inversely
by the respective numbers of trading days between the selling dates and the date as of which Fair Market Value is to be determined. If there are no such sale price quotations on or within a reasonable period both before and after the date as of
which Fair Market Value is to be determined, then Fair Market Value of the Common Stock shall be the mean between the bona fide bid and asked prices per share of Common Stock as so quoted for such date on NASDAQ, or if none, the weighted average of
the means between such bona fide bid and asked prices on the nearest trading date before and the nearest trading date after the date as of which Fair Market Value is to be determined, if both such dates are within a reasonable period. The average is
to be determined in the manner described above in this definition. If the Fair Market Value of the Common Stock cannot be determined on the basis previously set forth in this definition on the date as of which Fair Market Value is to be determined,
the Committee shall in good faith and in conformance with the requirements of Section 409A of the Code, to the extent applicable to an Award, determine the Fair Market Value of the Common Stock on such date. Fair Market Value shall be
determined without regard to any restriction other than a restriction which, by its terms, will never lapse. 
 (j)
“Free-Standing SARs” shall have the meaning set forth in Section 5.2. 
 (k) “Participant” means an
eligible employee, other service provider or a non-employee director of the Corporation or any Subsidiary or affiliate who has received an Award under the Plan and any transferee or transferees of such persons to the extent the transfer is permitted
under the Plan. 
 (l) “Performance Goals” means the performance goals, if any, established by the Committee in
connection with the grant of restricted stock, restricted stock units, 

  

 -3- 

 
performance units or other Awards. In the case of Qualified Performance-Based Awards, the “Performance Goals” means such performance goals based on

 (a) to select the Participants to whom Awards may be made; 
  

 -5- 

 (b) to determine whether and to what extent Awards are to be granted hereunder;

 (c) to determine the terms and conditions of each Award made hereunder, based on such factors as the Committee shall
determine; 
 (d) subject to Section 2.5, to modify, amend or adjust the terms and conditions of any previously granted
and outstanding Award; 
 (e) to adopt, alter and repeal such administrative rules, guidelines and practices governing the

under the Plan (and any agreement under Section 2.5 relating thereto);

Section 2.6, to accelerate the vesting or lapse of restrictions on any outstanding Award, other than a Qualified Performance-Based Award, based in each case on such considerations as the Committee in its sole discretion determines;

 (j) to establish any insider trading “blackout” period that the Committee in its sole discretion deems necessary or advisable; and 
 (k) to otherwise administer the Plan. 
 In determining any Award to be made to any eligible employee, the Committee shall
consider the position and the 

  

 -6- 

 
responsibilities of the employee being considered, the nature and value to the Corporation or a Subsidiary of his or her services, his or her present and/or
potential contribution to the success of the Corporation or a Subsidiary and such other factors as the Committee may deem relevant. The Committee may, except to the extent prohibited by applicable law or the listing standards of the stock exchange
which is the principal market for the Common Stock, allocate all or any portion of its responsibilities and powers to any one or more of its members and may delegate all or any part of its responsibilities and powers to any officers of the
Corporation or committee of officers of the Corporation selected by it, except with respect to Awards (including Qualified Performance-Based Awards) to any covered employees as defined in Section 162(m)(3) of the Code (“Covered
Employees”), persons subject to Section 16 of the Exchange Act, or non-employee directors. 
 2.2. Committee Action. The
Committee shall keep records of action taken at its meetings. A majority of the Committee shall constitute a quorum at any meeting and the acts of a majority of the members present at any meeting at which a quorum is present, or acts approved in
writing by all members of the Committee, shall be the acts of the Committee. 
 2.3 Committee Discretion. Any determination made by
the Committee or by an appropriately delegated officer pursuant to delegated authority under the provisions of the Plan with respect to any Award shall be made in the sole discretion of the Committee or such officer at the time of the Award or,
unless in contravention of any express term of the Plan, at any time thereafter. All decisions made by the Committee or any appropriately delegated officer pursuant to the provisions of the Plan shall be final and binding on all persons, including
the Corporation and the Participants eligible under the Plan. 
 2.4 Cancellation; Suspension; Clawback. Any or all outstanding Awards
to a Participant may at any time, in the Committee’s sole discretion and subject to such terms and conditions established by the Committee, be cancelled, suspended, or required to be repaid, as the case may be, to the Corporation if the
Participant (whether during employment or within eighteen (18) months after termination of employment or service with the Corporation and its Subsidiaries) (i) engages in the operation or management of a business (whether as owner,
partner, officer, director, employee or otherwise) which is in 

  

 -7- 

 
competition with the Corporation or any of its Subsidiaries, (ii) induces or attempts to induce any customer, supplier, licensee or other individual,
corporation or other business organization having a business relationship with the Corporation or any of its Subsidiaries to cease doing business with the Corporation or any of its Subsidiaries or in any way interferes with the relationship between
any such customer, supplier, licensee or other person and the Corporation or any of its Subsidiaries, (iii) solicits any employee of the Corporation or any of its Subsidiaries to leave the employment thereof or in any way interferes with the
relationship of such employee with the Corporation or any of its Subsidiaries, or (iv) makes any statements or comments, orally or in writing, of a defamatory or disparaging nature regarding the Corporation or any of its Subsidiaries (including
but not limited to regarding any of their respective businesses, officers, directors, personnel, products or policies); provided, however, that this sentence shall not apply following the occurrence of a Section 11 Event (as
defined in Section 11) unless the agreement under Section 2.5 specifically so provides; and provided, further, that to the extent that a Participant is a party to another agreement with the Corporation (such as an employment
agreement) that includes covenants with respect to one or more of the activities described in subsections (i) through (iv) above, the terms of the covenants in such other agreement shall instead be used in determining the applicability of
this Section 2.4 to the Participant. Whether a Participant has engaged in any such activities shall also be determined, in its sole discretion, by the Committee, and any such determination by the Committee shall be final and binding.

 2.5 Agreements. The terms and conditions of each Award shall be set forth in a written (or electronic) agreement, which shall be
delivered to the Participant receiving such Award upon, or as promptly as is reasonably practicable following, the making of such Award. The effectiveness of an Award shall be subject to the agreement being signed by the Corporation and the
Participant receiving the Award unless otherwise provided in the agreement. Unless otherwise provided in the agreement, each agreement or amendment thereto shall be executed on behalf of the Corporation by the Chief Executive Officer (if other than
the President), the President or any Vice President and by the Participant. The agreement confirming a stock option shall specify whether the stock option is an incentive stock option or a nonstatutory stock option. The provisions of such agreements

  

 -8- 

 
need not be identical. Without the consent of the Participant, upon notice to the Participant thereof, the Committee may amend any Award to the Participant
and the corresponding agreement in any respect not materially adverse to the Participant. All other amendments to the agreement shall be in writing (including electronic amendments) and executed on behalf of the Corporation and by the Participant.
Any reference in the Plan to the agreement under Section 2.5 shall include any amendment to such agreement. 
 2.6 Certain Minimum
Vesting Requirements. The Committee shall not be permitted to (a) make any Awards under Sections 6, 7 or 9 which do not, (i) in the case of time-based restrictions, contain a vesting period of less than three years, with no more
frequent than ratable vesting over such period, and (ii) in the case of performance based restrictions, contain a measurement period of less than one year, or (b) accelerate the vesting of any such Award in a manner which would cause such
Award to not comply with subsection (a) above, except in the case of the death, disability or retirement of a Participant or in the case of a Section 11 Event; provided, however, that the Committee shall be permitted to make
such Awards, or accelerate such vesting, in a manner that does not comply with subsection (a) or subsection (b) above, up to an aggregate of ten percent (10%) of the number of shares authorized for issuance under this Plan, subject to
adjustment as provided in Section 4.5. 
 SECTION 3 
 Eligibility 
 Those employees of the Corporation or any Subsidiary (including,
but not limited to, Covered Employees) who share responsibility for the management, growth or protection of the business of the Corporation or any Subsidiary, other service providers and/or non-employee directors of the Corporation or any Subsidiary
shall be eligible to receive Awards as described herein, provided however, that incentive stock options may be granted only to employees of the Corporation and Subsidiaries which are its subsidiaries within the meaning of Section 424(f) of the
Code. 
  

 -9- 

 SECTION 4 
 Shares Subject to the Plan 
 4.1 Number of Shares. Subject to adjustment as provided in
Section 4.5, the maximum aggregate number of shares of the Common Stock for which Awards may be made under the Plan shall be 2,000,000 shares. The maximum number of shares of Common Stock that may be granted pursuant to options intended to be
incentive stock options shall be 1,500,000 shares. 
 4.2 Individual Limit. The maximum number of shares of Common Stock as to which
Awards other than performance units under Section 8 or Awards under Section 9 may be made under the Plan to any one Participant in any one calendar year is 500,000 shares, subject to adjustment and substitution as set forth in
Section 4.5. For the purposes of this limitation, any adjustment or substitution made pursuant to Section 4.5 in a calendar year with respect to the maximum number of shares set forth in the preceding sentence shall also be made with
respect to any shares subject to Awards previously granted under the Plan to such Participant in the same calendar year. 
 4.3 Share
Counting. 
 (a) For purposes of the limit set forth in the first sentence of Section 4.1 (but not for purposes of
any other limit in this Plan, including in Section 4.2), each share of Common Stock which is subject to an Award other than a stock option or a stock appreciation right shall be counted as 1.38 shares rather than one (1) share,
provided, however, that in case of performance units and restricted stock units that have performance conditions, shares of Common Stock shall be counted as 1.38 shares rather than one (1) share for each actual share issued only
at the time, if any, of the actual issuance of shares pursuant to the performance unit Award. 
 (b) Except in the case of
Awards of performance units and restricted stock units that have performance conditions (where shares of Common Stock are counted only upon actual issuance of the shares pursuant to Section 4.3(a)), to the extent that any Award is forfeited, or
any option and the Tandem SAR (if any) or any Free-Standing SAR terminates, expires or lapses without being exercised, or any Award is 

  

 -10- 

 
settled for cash, the shares of Common Stock subject to such Awards (and the number of shares counted against the limit set forth in the first sentence of
Section 4.1 with respect to such Awards) shall again be available for Awards under the Plan under Section 4.1. However, shares of Common Stock subject to such Awards shall continue to be counted for purposes of Section 4.2 or
Section 9, as applicable. 
 (c) If the exercise price of any option and/or the tax withholding obligations relating to
any Awards are satisfied by delivering shares (either actually or through attestation) or withholding shares relating to such Award, the gross number of shares subject to the Award shall nonetheless be deemed to have been granted for purposes of
Sections 4.1 and 4.2 and any shares which are delivered will not be added to the aggregate number of shares under Section 4.1 for which Awards may be made under the Plan. 
 (d) If a Tandem SAR is granted, each share of Common Stock subject to both the Tandem SAR and related stock option shall be counted as
only one share of Common Stock for purposes of Sections 4.1 and 4.2. 
 (e) Each share of Common Stock subject to a stock
option (with or without a Tandem SAR) or a Free-Standing SAR shall be counted as one share of Common Stock for purposes of Sections 4.1 and 4.2. 
 (f) All shares of Common Stock covered by a stock appreciation right, to the extent it is exercised and shares of Common Stock are actually issued upon exercise of the right, shall be counted for purposes of Sections
4.1 and 4.2, regardless of the number of shares used to settle the stock appreciation right upon exercise. 
 4.4 Common Stock. To the
extent that the Corporation has such shares of Common Stock available to it and can issue such shares without violating any law or regulation, the Corporation will reserve Common Stock for issuance with respect to an Award payable in Common Stock.
The shares of Common Stock which may be issued under the Plan may be either authorized but unissued shares or shares previously issued and thereafter acquired by the Corporation or partly each, as shall be determined from time to time by the Board.

 4.5 Adjustment and Substitution of Shares. In the event of a merger, consolidation, stock rights
offering, liquidation, separation, spinoff, disaffiliation of a Subsidiary from the Corporation, extraordinary dividend of cash or other property, or similar event affecting the Corporation or any of its Subsidiaries (each, a “Corporate
Transaction”), or in the event of a stock dividend, stock split, reverse stock split, reorganization, share combination, or recapitalization or similar event affecting the capital structure of the Corporation (each, a “Share Change”),
the Committee or the Board shall make such substitutions or adjustments as it deems appropriate and equitable to prevent the dilution or enlargement of the rights of Participants to (A) the aggregate number and kind of shares of Common Stock
reserved for issuance and delivery under the Plan, (B) the various maximum limitations set forth in Sections 4.1 and 4.2 upon certain types of Awards and upon the Awards to individuals, (C) the number and kind of shares of Common Stock
subject to outstanding Awards; and (D) the exercise price of outstanding Awards. In the case of Corporate Transactions, such adjustments may include, without limitation, (1) the cancellation of outstanding Awards in exchange for payments
of cash, property or a combination thereof having an aggregate value equal to the value of such Awards, as determined by the Committee or the Board in its sole discretion (it being understood that in the case of a Corporate Transaction with respect
to which shareholders of Common Stock receive consideration other than publicly-traded equity securities of the ultimate surviving entity, any such determination by the Committee that the value of an option or stock appreciation right shall for this
purpose be deemed to equal the excess, if any, of the value of the consideration being paid for each share pursuant to such Corporate Transaction over the exercise price of such option or stock appreciation right shall conclusively be deemed valid);
(2) the substitution of other property (including, without limitation, cash or other securities of the Corporation and securities of entities other than the Corporation) for the shares subject to outstanding Awards; and (3) in connection
with any disaffiliation of a Subsidiary, arranging for the assumption of Awards, or replacement of Awards with new Awards based on other property or other securities (including, without limitation, other securities of the Corporation and securities
of entities other than the Corporation), by the affected Subsidiary, or by the entity that controls such Subsidiary following such disaffiliation (as well 

  

 -12- 

 
as any corresponding adjustments to Awards that remain based upon Corporation securities). The Committee shall adjust the Performance Goals applicable to any
Awards to reflect any unusual or non-recurring events and other extraordinary items, impact of charges for restructurings, discontinued operations, and the cumulative effects of accounting or tax changes, each as defined by generally accepted
accounting principles or as identified in the Corporation’s financial statements, notes to the financial statements, management’s discussion and analysis or other of the Corporation’s SEC filings; provided, however, that
in the case of Performance Goals applicable to any Qualified Performance-Based Awards, such adjustment does not violate Section 162(m) of the Code or cause such Awards not to qualify for the Section 162(m) Exemption, as defined in
Section 12.1. No adjustment or substitution provided in this Section 4.5 shall require the Corporation or any other entity to issue or sell a fraction of a share or other security. 
 4.6 Section 409A; Section 162(m); Incentive Stock Options. Notwithstanding the foregoing: (i) any adjustments made pursuant to
Section 4.5 to Awards that are considered “deferred compensation” within the meaning of Section 409A of the Code shall be made in compliance with the requirements of Section 409A of the Code; (ii) any adjustments made
pursuant to Section 4.5 to Awards that are not considered “deferred compensation” subject to Section 409A of the Code shall be made in such a manner as to ensure that after such adjustment, the Awards either (A) continue not
to be subject to Section 409A of the Code or (B) comply with the requirements of Section 409A of the Code; and (iii) in any event, neither the Committee nor the Board shall have the authority to make any adjustments pursuant to
Section 4.5 to the extent the existence of such authority would cause an Award that is not intended to be subject to Section 409A of the Code at the grant date of the Award to be subject thereto. If any such adjustment or substitution
provided for in Section 4.5 requires the approval of shareholders in order to enable the Corporation to grant incentive stock options or to comply with Section 162(m) of the Code, then no such adjustment or substitution shall be made
without the required shareholder approval. Notwithstanding the foregoing, in the case of incentive stock options, if the effect of any such adjustment or substitution would be to cause the option to fail to continue to qualify as an incentive stock
option or to cause a modification, extension or renewal of such option within the meaning of Section 424 of the Code, the 

  

 -13- 

 
Committee may determine that such adjustment or substitution not be made but rather shall use reasonable efforts to effect such other adjustment of each then
outstanding incentive stock option as the Committee, in its sole discretion, shall deem equitable and which will not result in any disqualification, modification, extension or renewal (within the meaning of Section 424 of the Code) of such
incentive stock option. 
 SECTION 5 
 Grant of Stock Options and Stock Appreciation Rights 
 5.1 Types of Options; Limit on Incentive
Stock Options. The Committee shall have authority, in its sole discretion, to grant “incentive stock options” pursuant to Section 422 of the Code, to grant “nonstatutory stock options” (i.e., stock options which do not
qualify under Sections 422 or 423 of the Code) or to grant both types of stock options (but not in tandem). Notwithstanding any other provision contained in the Plan or in any agreement under Section 2.5, but subject to the possible exercise of
the Committee’s discretion contemplated in the last sentence of this Section 5.1, the aggregate Fair Market Value on the date of grant of the shares with respect to which such incentive stock options are exercisable for the first time by a
Participant during any calendar year under all plans of the corporation employing such Participant, any parent or subsidiary corporation of such corporation and any predecessor corporation of any such corporation shall not exceed $100,000 or such
other applicable amount as may from time to time be set forth in the Code. If the date on which one or more incentive stock options could first be exercised would be accelerated pursuant to any provision of the Plan or any agreement under
Section 2.5 and the acceleration of such exercise date would result in a violation of the $100,000 restriction set forth in the preceding sentence, then, notwithstanding any such provision, but subject to the provisions of the next succeeding
sentence, the exercise dates of such incentive stock options shall be accelerated only to the extent, if any, that does not result in a violation of such restriction and, in such event, the exercise dates of the incentive stock options with the
lowest option prices shall be accelerated to the earliest such dates. The Committee may, in its sole discretion, authorize the acceleration of the exercise date of one or more incentive stock options even if such acceleration would violate the
$100,000 restriction set forth in 

  

 -14- 

 
the second sentence of this Section 5.1 and even if one or more such incentive stock options are thereby converted in whole or in part to nonstatutory
stock options. 
 5.2 Types and Nature of Stock Appreciation Rights. Stock appreciation rights may be tandem stock appreciation rights
which are granted in conjunction with incentive stock options or nonstatutory stock options (“Tandem SARs”), or stock appreciation rights which are not granted in conjunction with options (“Free-Standing SARs”). Upon the exercise
of a stock appreciation right, the Participant shall be entitled to receive an amount in cash, shares of Common Stock, or both, in value equal to the product of (i) the excess of the Fair Market Value of one share of Common Stock on the date of
exercise of the stock appreciation right over, in the case of a Tandem SAR, the exercise price of the related option, or in the case of a Free-Standing SAR, the Base Price per share (the “Spread”), multiplied by (ii) the number of
shares of Common Stock in respect of which the stock appreciation right has been exercised. Notwithstanding the foregoing, the Committee at the time it grants a stock appreciation right may provide that the Spread covered by such stock appreciation
right may not exceed a lower specified amount. The applicable agreement under Section 2.5 governing the stock appreciation rights shall specify whether such payment is to be made in cash or Common Stock or both, or shall reserve to the
Committee or the Participant the right to make that determination prior to or upon the exercise of the stock appreciation right. Tandem SARs may be granted at the grant date of the related stock options or, in the case of a related nonstatutory
stock option, also at a later date. At the time a Tandem SAR is granted, the Committee may limit the exercise period for such Tandem SAR, before and after which period no Tandem SAR shall attach to the underlying stock option. In no event shall the
exercise period for a Tandem SAR exceed the exercise period for the related stock option. A Tandem SAR shall be exercisable only at such time or times and to the extent that the related option is exercisable in accordance with the provisions of this
Section 5. A Tandem SAR shall terminate or be forfeited upon the exercise or forfeiture of the related stock option, and the related stock option shall terminate or be forfeited upon the exercise or forfeiture of the Tandem SAR. Any Tandem SAR
granted with a related incentive stock option shall be exercisable only when the Fair Market Value of a share of Common Stock exceeds the exercise price for a share of Common Stock under the related incentive stock option. 
  

 -15- 

 5.3 Exercise Price and Base Price. The exercise price per share of Common Stock subject to an
option and any Tandem SAR, and the base price per share for any Free-Standing SAR (the “Base Price”), shall be determined by the Committee and set forth in the applicable agreement under Section 2.5, and shall be not less than the
Fair Market Value of a share of the Common Stock on the applicable grant date, except that in the case of an incentive stock option granted to a Participant who, immediately prior to such grant, owns stock possessing more than ten percent
(10%) of the total combined voting power of all classes of stock of the Corporation or any Subsidiary which is a corporation (a “Ten Percent Participant”), the exercise price shall be not less than one hundred ten percent
(110%) of the Fair Market Value on the date of grant. For purposes of this Section 5.3, an individual (i) shall be considered as owning not only shares of stock owned individually but also all shares of stock that are at the time
owned, directly or indirectly, by or for the spouse, ancestors, lineal descendants and brothers and sisters (whether by the whole or half blood) of such individual and (ii) shall be considered as owning proportionately any shares owned,
directly or indirectly, by or for any corporation, partnership, estate or trust in which such individual is a shareholder, partner or beneficiary. In no event may any option or stock appreciation right granted under this Plan, other than pursuant to
Section 4.5, be amended to decrease the exercise price or Base Price thereof, be cancelled in conjunction with the grant of any new option or stock appreciation right with a lower exercise price or Base Price, be cancelled or repurchased for
cash, property, or another Award at a time when the exercise price or Base Price is greater than the Fair Market Value of the underlying Common Stock, or otherwise be subject to any action that would be treated, for accounting purposes, as a
“repricing” of such option or stock appreciation right, unless such amendment, cancellation, or action is approved by the Corporation’s shareholders. 
 5.4 Term; Vesting and Exercisability. The expiration date of each option and each stock appreciation right shall be fixed by the Committee, but shall not exceed ten years from the date of grant (five years in
the case of an incentive stock option granted to a Ten Percent Participant). Except as otherwise provided herein, options and stock appreciation rights shall be 

  

 -16- 

 
exercisable at such time or times and subject to such terms and conditions as shall be determined by the Committee and may be exercisable commencing with the
grant date. 
 5.5 Method of Exercise. Subject to the provisions of this Section 5, options and stock appreciation rights may be
exercised, in whole or in part (unless otherwise specified by the Committee in its sole discretion), at any time prior to their expiration date by giving written notice of exercise to the Corporation specifying the number of shares of Common Stock
as to which the option or stock appreciation rights is being exercised. In the case of the exercise of an option, such notice shall be accompanied by payment in full of the exercise price in United States of America dollars. If approved by the
Committee (at the time of grant in the case of an incentive stock option or at any time in the case of a nonstatutory stock option), payment, in full or in part, may also be made as follows: 
 (a) Payment may be made in the form of unrestricted shares of Common Stock (by delivery of such shares or by attestation) of the same
class as the Common Stock subject to the option already owned by the Participant (based on the Fair Market Value of the Common Stock on the date the option is exercised) provided however, that any portion of the exercise price representing a
fraction of a share shall be paid in cash; 
 (b) To the extent permitted by applicable law, payment may be made by delivering
a properly executed exercise notice to the Corporation, together with a copy of irrevocable instructions to a broker to deliver promptly to the Corporation the amount of sale or loan proceeds necessary to pay the exercise price, and, if requested,
the amount of any federal, state, local or foreign withholding taxes. To facilitate the foregoing, the Corporation may, to the extent permitted by applicable law, enter into agreements for coordinated procedures with one or more brokerage firms. In
the event the broker sells any shares on behalf of a Participant, the broker shall be acting solely as the agent of the Participant, and the Corporation disclaims any responsibility for the actions of the broker in making any such sales; and/or

  

 -17- 

 (c) With such other instrument as approved by the Committee, including Corporation loans,
to the extent permitted by applicable law. 
 5.6 Delivery; Rights of Shareholders. No shares shall be delivered pursuant to the
exercise of an option until the exercise price for the option has been fully paid and applicable taxes have been withheld. Unless otherwise specified by the Committee, the applicable Participant shall have all of the rights of a shareholder of the
Corporation holding Common Stock with respect to the shares of Common Stock to be issued upon the exercise of the option or stock appreciation right (including the right to vote the applicable shares and the right to receive dividends), when the
Participant (i) has given written notice of exercise in accordance with the procedures established by the Committee, (ii) if requested, has given the representation described in Section 10, and (iii) in the case of an option, has
paid in full the exercise price for such shares. 
 5.7 Nontransferability of Options and Stock Appreciation Rights. Unless the
Committee shall otherwise determine in the case of nonstatutory stock options and stock appreciation rights and limited to a transfer without the payment of value or consideration to the Participant, (i) no option or stock appreciation right
shall be transferable by a Participant other than by will, or if the Participant dies intestate, by the laws of descent and distribution of the state of domicile of the Participant at the time of death, and (ii) all stock options and stock
appreciation rights shall be exercisable during the lifetime of the Participant only by the Participant (or the Participant’s guardian or legal representative). Any Tandem SAR shall be transferable only when the related stock option is
transferable and then only with the related stock option. 
 5.8 Termination of Employment. Unless the Committee, in its sole
discretion, shall otherwise determine at the time of grant of the Award or, other than in the case of incentive stock options, thereafter, but subject to the provisions of Section 5.1 in the case of incentive stock options: 
 (a) If the employment or engagement of a Participant who is not disabled within the meaning of Section 422(c)(6) of the Code (a
“Disabled Participant”) is voluntarily terminated with the consent of the Corporation or a Subsidiary, any then outstanding incentive stock option 

  

 -18- 

 
held by such Participant shall be exercisable by the Participant (but only to the extent exercisable by the Participant immediately prior to the termination
of employment) at any time prior to the expiration date of such incentive stock option or within three months after the date of termination of employment, whichever is the shorter period; 
 (b) If the employment or engagement of a Participant who is not a Disabled Participant is voluntarily terminated with the consent of the
Corporation or a Subsidiary, any then outstanding nonstatutory stock option or stock appreciation right held by such Participant shall be exercisable by the Participant (but only to the extent exercisable by the Participant immediately prior to the
termination of employment) at any time prior to the expiration date of such nonstatutory stock option or stock appreciation right or within one year after the date of termination of employment, whichever is the shorter period; 
 (c) If the employment or engagement of a Participant who is a Disabled Participant is voluntarily terminated with the consent of the
Corporation or a Subsidiary, or a Participant retires at normal retirement age (not early retirement) under any retirement plan of the Corporation, any then outstanding stock option or stock appreciation right held by such Participant shall be
exercisable in full (whether or not so exercisable by the Participant immediately prior to the termination of employment) by the Participant at any time prior to the expiration date of such stock option or stock appreciation right or within one year
after the date of termination of employment, whichever is the shorter period; 
 (d) Following the death of a Participant
either during or after the termination of employment or engagement, any outstanding stock option or stock appreciation right held by the Participant at the time of death shall be exercisable in full (whether or not so exercisable by the Participant
immediately prior to the death of the Participant) by the person entitled to do so under the will of the Participant, or, if the Participant shall fail to make testamentary disposition of the stock option or stock appreciation right or shall die
intestate, by the legal representative of the Participant at any time 

  

 -19- 

 
prior to the expiration date of such stock option or stock appreciation right or within one year after the date of death, whichever is the shorter period;
and 
 (e) Unless the exercise period of a stock option or stock appreciation right following termination of employment or
engagement has been extended as provided in Section 11.3, if the employment or engagement of a Participant terminates for any reason other than voluntary termination with the consent of the Corporation or a Subsidiary, retirement under any
retirement plan of the Corporation or a Subsidiary or death, all outstanding stock options and stock appreciation rights held by the Participant at the time of such termination of employment or engagement shall automatically terminate. 

Whether termination of employment or engagement is a voluntary termination with the consent of the Corporation or a Subsidiary, whether a retirement is at normal
retirement age under a retirement plan of the Corporation, and whether a Participant is a Disabled Participant shall be determined in each case, in its sole discretion, by the Committee (or, in the case of Participants who are not (i) Covered
Employees as of the end of the Corporation’s immediately preceding fiscal year or (ii) the Chief Executive Officer of the Corporation, by such Chief Executive Officer, in his sole discretion) and any such determination by the Committee or
such Chief Executive Officer shall be final and binding. Without limitation of the foregoing, a termination of employment or engagement by the Participant shall not be a voluntary termination with the consent of the Corporation unless the Committee
or, if applicable, such Chief Executive Officer, in its or his sole discretion, specifically consents to the termination of employment or engagement in writing. 
 5.9 Termination of Service. In the case of Participants who are non-employee directors, unless the Committee, in its sole discretion, shall otherwise determine at the time of grant of the Award or thereafter:

 (a) If the service of a Participant is terminated for reasons other than removal for cause, any then outstanding stock
option or stock appreciation right held by such Participant shall be exercisable by the Participant (but 

  

 -20- 

 
only to the extent exercisable by the Participant immediately prior to the termination of service) at any time prior to the expiration date of such stock
option or stock appreciation right or within one year after the date of termination of service, whichever is the shorter period; 
 (b) Following the death of a Participant either during or after the termination of service, any outstanding stock option or stock appreciation right held by the Participant at the time of death shall be exercisable in full (whether or not
so exercisable by the Participant immediately prior to the death of the Participant) by the person entitled to do so under the will of the Participant, or, if the Participant shall fail to make testamentary disposition of the stock option or stock
appreciation right or shall die intestate, by the legal representative of the Participant at any time prior to the expiration date of such stock option or stock appreciation right or within one year after the date of death, whichever is the shorter
period; and 
 (c) Unless the exercise period of a stock option or stock appreciation right following termination of service
has been extended as provided in Section 11.3, if the service of a Participant terminates due to a removal for cause, all outstanding stock options and stock appreciation rights held by the Participant at the time of such termination of service
shall automatically terminate. 
 Whether termination of service due to a removal for cause shall be determined in each case, in its sole discretion, by the
Committee and any such determination by the Committee shall be final and binding. 
 5.10 Other Terms and Conditions. Subject to the
foregoing provisions of this Section 5 and the other provisions of the Plan, any stock option or stock appreciation right granted under the Plan may be exercised at such times and in such amounts and be subject to such restrictions and other
terms and conditions, if any, as shall be determined, in its sole discretion, by the Committee and set forth in the agreement under Section 2.5. 
  

 -21- 

 SECTION 6 
 Restricted Stock 
 6.1 Restricted Stock Awards; Certificates. Shares of restricted stock are
actual shares of Common Stock issued to a Participant, and shall be evidenced in such manner as the Committee may deem appropriate, including book-entry registration or issuance of one or more stock certificates. Any certificate issued in respect of
shares of restricted stock shall be registered in the name of the applicable Participant and, unless held by or on behalf of the Corporation in escrow or custody until the restrictions lapse or the shares are forfeited, shall bear an appropriate
conspicuous legend referring to the terms, conditions, and restrictions applicable to such Award, substantially in the following form: 
 “The transferability of this certificate and the shares of stock represented hereby are subject to the terms and conditions (including forfeiture) of the Calgon Carbon Corporation 2008 Equity Incentive Plan and a corresponding
agreement. Copies of such Plan and agreement are on file at the offices of Calgon Carbon Corporation, 400 Calgon Carbon Drive, Pittsburgh, PA 15205.” 
 The Committee may require that the certificates evidencing such shares be held in escrow or custody by or on behalf of the Corporation until the restrictions thereon shall have lapsed or the shares are forfeited and that, as a condition of
any Award of restricted stock, the applicable Participant deliver to the Corporation a stock power, endorsed in blank, relating to the Common Stock covered by such Award. 
 6.2 Terms and Conditions. Shares of restricted stock shall be subject to the following terms and conditions: 
 (a) Subject to Section 2.6, the Committee shall, prior to or at the time of grant, condition the vesting of an Award of restricted stock upon (i) the continued service of the applicable Participant,
(ii) the attainment of Performance Goals, or (iii) the attainment of Performance Goals and the continued service of the applicable Participant. The Committee shall establish at the time the restricted stock is granted the performance
periods during 

  

 -22- 

 
which any Performance Goals specified by the Committee with respect to the restricted stock Award are to be measured. In the event that the Committee
conditions the vesting of an Award of restricted stock upon the attainment of Performance Goals or the attainment of Performance Goals and the continued service of the applicable Participant, the Committee may, prior to or at the time of grant,
designate an Award of restricted stock as a Qualified Performance-Based Award. The conditions for vesting and the other provisions of restricted stock Awards (including without limitation any applicable Performance Goals) need not be the same with
respect to each recipient, and shall be established by the Committee in its sole discretion. Except in the case of a Qualified Performance-Based Award, the Committee at any time after the date of grant, in its sole discretion, may modify or waive
any of the conditions applicable to an Award of restricted stock. 
 (b) Subject to the provisions of this Plan (including
Section 6.3) and the applicable agreement under Section 2.5, during the period, if any, set by the Committee, commencing with the date of such restricted stock Award for which such vesting restrictions apply (the “Restriction
Period”), and until the expiration of the Restriction Period, the Participant shall not be permitted to sell, assign, transfer, pledge or otherwise encumber shares of such restricted stock. A restricted stock Award may vest in part on a pro
rata basis prior to the expiration of any Restriction Period. 
 (c) Except as provided in this Section 6 and in the
applicable agreement under Section 2.5, the applicable Participant shall have, with respect to the shares of restricted stock, all of the rights of a shareholder of the Corporation holding the Common Stock that is the subject of the restricted
stock, including, if applicable, the right to vote the shares and the right to receive any cash dividends. If so determined by the Committee and set forth in the applicable agreement under Section 2.5 and subject to Section 15.4, cash
dividends on the Common Stock that is the subject of the restricted stock Award may be (i) automatically deferred and reinvested in additional restricted stock, and held subject to the same vesting and forfeiture conditions of the underlying
restricted stock, or (ii) held by the Corporation in cash (without any 

  

 -23- 

 
payment of interest thereon) subject to the same vesting and forfeiture conditions of the restricted stock with respect to which the dividends are payable.
Unless otherwise determined by the Committee and set forth in the applicable agreement under Section 2.5, any Common Stock or other securities payable with respect to any restricted stock as a result of or pursuant to Section 4.5, shall be
held subject to the same vesting and forfeiture conditions of the underlying restricted stock. 
 (d) As soon as practicable
after the applicable Restriction Period has ended, the Committee shall determine and certify (in writing in the case of Qualified Performance-Based Awards) whether and the extent to which the service period and/or the Performance Goals were met for
the applicable restricted stock. If the vesting condition or conditions applicable to the restricted stock are not satisfied by the time the Restriction Period has expired, such restricted stock shall be forfeited. If and when the Restriction Period
expires without a prior forfeiture of the shares of restricted stock (i) if legended certificates have been issued, unlegended certificates for such shares shall be delivered to the Participant upon surrender of the legended certificates,
(ii) if legended certificates have not yet been issued, unlegended certificates (and any related blank stock powers previously executed by the Participant) shall be delivered to the Participant, and (iii) any cash dividends held by the
Corporation pursuant to Section 6.2(c) shall be delivered to the Participant. 
 6.3 Permitted Transfers. Neither this
Section 6 nor any other provision of the Plan shall preclude a Participant from transferring or assigning restricted stock, without the payment of value or consideration to the Participant, to (i) the trustee of a trust that is revocable
by such Participant alone, both at the time of the transfer or assignment and at all times thereafter prior to such Participant’s death or (ii) the trustee of any other trust to the extent approved in advance by the Committee, in its sole
discretion, in writing. A transfer or assignment of restricted stock from such trustee to any person other than such Participant shall be permitted only to the extent approved in advance by the Committee, in its sole discretion, in writing, and
restricted stock held by such trustee shall be subject to all of the conditions and 

  

 -24- 

 
restrictions set forth in the Plan and in the applicable agreement under Section 2.5 as if such trustee were a party to such agreement. 
 SECTION 7 
 Restricted Stock
Units 
 7.1 Restricted Stock Unit Awards. Restricted stock units are Awards denominated in shares of Common Stock that will be
settled, subject to the terms and conditions of the restricted stock units and at the sole discretion of the Committee, in an amount in cash, shares of Common Stock, or both, based upon the Fair Market Value of a specified number of shares of Common
Stock. 
 7.2 Terms and Conditions. Restricted stock units shall be subject to the following terms and conditions: 
 (a) Subject to Section 2.6, the Committee shall, prior to or at the time of grant, condition the vesting of restricted stock units
upon (i) the continued service of the applicable Participant, (ii) the attainment of Performance Goals or (iii) the attainment of Performance Goals and the continued service of the applicable Participant. In the event that the
Committee conditions the vesting of restricted stock units upon the attainment of Performance Goals or the attainment of Performance Goals and the continued service of the applicable Participant, the Committee may, prior to or at the time of grant,
designate the restricted stock units as a Qualified Performance-Based Awards. The Committee shall determine the performance period(s) during which any Performance Goals are to be achieved. The conditions for grant or vesting and the other provisions
of restricted stock units (including without limitation any applicable Performance Goals) need not be the same with respect to each recipient. An Award of restricted stock units shall be settled as and when the restricted stock units vest, as
determined and certified (in writing in the case of Qualified Performance-Based Awards) by the Committee, or at a later time specified by the Committee or in accordance with an election of the Participant, if the Committee so permits. Except in the
case of a Qualified Performance-Based Award, the Committee at any time after the date of grant, in its sole discretion, may modify or waive any of the conditions applicable to an Award of restricted stock units. 
  

 -25- 

 (b) Subject to the provisions of the Plan and the applicable agreement under
Section 2.5, during the period, if any, set by the Committee, commencing with the date of grant of such restricted stock units for which such vesting restrictions apply (the “Units Restriction Period”), and until the expiration of the
Units Restriction Period, the Participant shall not be permitted to sell, assign, transfer, pledge or otherwise encumber restricted stock units. A restricted stock unit may vest in part prior to the expiration of any Units Restriction Period.

 (c) Participants granted restricted stock units shall not be entitled to any dividends payable on the Common Stock unless
the agreement under Section 2.5 for restricted stock units specifies to what extent and on what terms and conditions the applicable Participant shall be entitled to receive current or deferred payments of cash, Common Stock or other property
corresponding to the dividends payable on the Common Stock (subject to Section 15.4 below). Restricted stock units shall not have any voting rights, and holders of restricted stock units shall not be shareholders of the Corporation unless and
until shares of Common Stock are issued by the Corporation (in book-entry form or otherwise). 
 SECTION 8 
 Performance Units 
 Performance units
may be granted hereunder to eligible Participants, for no cash consideration or for such minimum consideration as may be required by applicable law, either alone or in addition to other Awards granted under the Plan. The Committee shall establish at
the time the performance unit is granted the performance period(s) during which any Performance Goals specified by the Committee with respect to the Award are to be measured. The Performance Goals to be achieved during any performance period(s) and
the length of the performance period(s) shall be determined by the Committee upon the grant of each performance unit. The Committee may, in connection with the grant of performance units, designate them as Qualified 

  

 -26- 

 
Performance-Based Awards. The conditions for grant or vesting and the other provisions of performance units (including without limitation any applicable
Performance Goals) need not be the same with respect to each Participant. Performance units may be paid in cash, shares of Common Stock, other property or any combination thereof, in the sole discretion of the Committee as set forth in the
applicable agreement under Section 2.5. Performance units shall not have any voting rights, and holders of performance units shall not be shareholders of the Corporation unless and until shares of Common Stock are issued by the Corporation (in
book-entry form or otherwise). The Performance Goals to be achieved for each performance period, whether the Performance Goals have been achieved, and the amount of the Award to be distributed shall be conclusively determined and certified (in
writing in the case of Qualified Performance-Based Awards) by the Committee. Performance units may be paid in a lump sum or in installments following the close of the performance period(s). The Participant shall not be permitted to sell, assign,
transfer, pledge or otherwise encumber performance units. The maximum value of the property, including cash, that may be paid or distributed to any Participant pursuant to a grant of performance units made in any one calendar year shall be five
million United States of America dollars ($5,000,000). 
 SECTION 9 
 Other Stock-Based Awards 
 The Committee may award Common Stock and other Awards
that are valued in whole or in part by reference to, or are otherwise based upon, Common Stock, including but not limited to, unrestricted stock or dividend equivalents. Any such Award shall be subject to such terms and conditions as established by
the Committee, and may include Qualified Performance-Based Awards. The maximum value of Common Stock and other property, including cash, that may be paid or distributed to any Participant pursuant to this Section 9 (and not pursuant to other
sections of the Plan) in any one calendar year shall be five million United States of America dollars ($5,000,000).

 SECTION 10 
 Issuance of Shares 
 The Committee may require each person purchasing or receiving shares of Common
Stock pursuant to an Award to represent to and agree with the Corporation in writing that such person is acquiring the shares without a view to the distribution thereof. The certificates for such shares may include any legend which the Committee
deems appropriate to reflect any restrictions on transfer. The obligation of the Corporation to issue shares of Common Stock under the Plan shall be subject to (i) the effectiveness of a registration statement under the Securities Act of 1933,
as amended, with respect to such shares, if deemed necessary or appropriate by counsel for the Corporation, (ii) the condition that the shares shall have been listed (or authorized for listing upon official notice of issuance) upon each stock
exchange, if any, on which the shares of Common Stock may then be listed, (iii) all other applicable laws, regulations, rules and orders which may then be in effect and (iv) obtaining any other consent, approval, or permit from any state
or federal governmental agency which the Committee shall, in its sole discretion, determine to be necessary or advisable. 
 SECTION 11 
 Additional Rights in Certain Events 
 11.1 Definitions.

this Section 11, the following terms shall have the following meanings: 
 (a) “Section 11 Event” shall mean the
date upon which any of the following events occurs: 
 (i) The acquisition by any individual, entity or group (a
“Person”) (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of either (A) the then
outstanding shares of common stock of the Corporation (the “Outstanding Corporation Common Stock”) or (B) the combined voting power of the then outstanding voting securities of 

  

 -28- 

 
the Corporation entitled to vote generally in the election of directors (the “Outstanding Corporation Voting Securities”); provided,
however, that, for purposes of this subsection (i), the following acquisitions shall not constitute a Change of Control: (x) any acquisition directly from the Corporation, (y) any acquisition by the Corporation or (z) any
acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Corporation; 
 (ii) Any time at
which individuals who, as of the date hereof, constitute the Board (the “Incumbent Board”) cease for any reason to constitute at least two-thirds (2/3) of the Board; provided, however, that any individual becoming
a director subsequent to the date hereof whose election, or nomination for election by the Corporation’s stockholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as
though such individual were a member of the Incumbent Board, provided, that for this purpose, the Incumbent Board shall not include any such individual whose initial assumption of office occurs as a result of an actual or threatened election
contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board (any individual not included in the Incumbent Board by reason of this
proviso shall be excluded permanently for purposes of determining whether the Incumbent Board has at any time ceased for any reason to constitute at least two-thirds (2/3) of the Board); 
 (iii) Consummation of a reorganization, merger, statutory share exchange or consolidation or similar corporate transaction involving the
Corporation or any of its subsidiaries, a sale or other disposition of all or substantially all of the assets of the Corporation, or the acquisition of assets or stock of another entity by the Corporation or any of its subsidiaries (each, a
“Business Combination”), in each case unless, following such Business Combination, (A) all or substantially all of the individuals and entities that were the beneficial owners of the Outstanding Corporation Common Stock and the
Outstanding Corporation Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of the then outstanding shares of common stock and the combined voting power of the then outstanding
voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Business Combination (including, without limitation, a corporation that, as a result of such transaction, owns such
voting power of the shares of the Corporation or all or substantially all of the 

  

 -29- 

 
Corporation’s assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership immediately prior to
such Business Combination of the Outstanding Corporation Common Stock and the Outstanding Corporation Voting Securities, as the case may be, (B) no Person (excluding any corporation resulting from such Business Combination or any employee
benefit plan (or related trust) of the Corporation or such corporation resulting from such Business Combination) beneficially owns, directly or indirectly, 20% or more of, respectively, the then outstanding shares of common stock of the corporation
resulting from such Business Combination or the combined voting power of the then outstanding voting securities of such corporation, except to the extent that such ownership existed prior to the Business Combination, and (C) at least two-thirds
(2/3) of the members of the board of directors of the corporation resulting from such Business Combination were members of the Incumbent Board at the time of the execution of the initial agreement or of the action of the Board providing for
such Business Combination; or 
 (iv) Approval by the stockholders of the Corporation of a complete liquidation or dissolution
of the Corporation. 
 (b) “Covered Change of Control Termination” shall mean (i) the termination of Participant’s
employment by the Corporation other than for Cause during the one-year period after a Section 11 Event or (ii) the termination of Participant’s employment by Participant during the one-year period after a Section 11 Event, in the
case in which the Corporation has required the Participant to be based at a location in excess of thirty-five miles from the location of Participant’s principal job location or office immediately prior to such change. 
 (c) “Cause” shall mean Participant’s (i) willful misconduct in the performance of his or her duties (other than for
Disability); (ii) dishonesty or breach of trust by Participant which is demonstrably injurious to the Corporation or its Subsidiaries; (iii) conviction for or plea of nolo contendere to a felony; (iv) insubordination or failure
to follow directives issued by a superior at the Corporation or by the Board of Directors; (v) actions which cause a breach or violation of securities laws (including the Sarbanes-Oxley Act or any rules or regulations related thereto); or
(vi) material violations of a Corporation policy. 
 11.2 Acceleration of the Exercise Date of Stock Options and Stock Appreciation
Rights. Subject to the provisions of Section 5 in the case of incentive stock options and 

  

 -30- 

 
Section 11.6, unless the agreement under Section 2.5 shall otherwise provide, and notwithstanding any other provision contained in the Plan other
than Section 11.7, in case any Covered Change of Control Termination occurs with respect to a Participant, all outstanding stock options and stock appreciation rights of such Participant shall become immediately and fully exercisable whether or
not otherwise exercisable by their terms. 
 11.3 Extension of the Expiration Date of Stock Options and Stock Appreciation Rights.
Subject to the provisions of Section 5 in the case of incentive stock options and Section 11.6, unless the agreement under Section 2.5 shall otherwise provide, and notwithstanding any other provision contained in the Plan other than
Section 11.7, all stock options and stock appreciation rights held by a Participant whose employment with the Corporation or a Subsidiary terminates by a Covered Change of Control Termination shall be exercisable for a period of three months
from the date of such termination of employment, but in no event after the expiration date of the stock option or stock appreciation right. 
 11.4 Lapse of Restrictions on Restricted Stock Awards. Unless the agreement under Section 2.5 shall otherwise provide, and notwithstanding any other provision contained in the Plan other than Section 11.6 and
Section 11.7, if any Covered Change of Control Termination occurs with respect to a Participant prior to the scheduled lapse of all restrictions applicable to restricted stock Awards of such Participant under the Plan (including but not limited
to Qualified Performance-Based Awards), all such restrictions shall lapse upon the occurrence of any such Covered Changed of Control Termination regardless of the scheduled lapse of such restrictions. 
 11.5 Vesting of Restricted Stock Units and Performance Units. Unless the agreement under Section 2.5 shall otherwise provide, and
notwithstanding any other provision contained in the Plan other than Section 11.6 and Section 11.7, if any Covered Change of Control Termination occurs with respect to a Participant, all restricted stock units and performance units
(including but not limited to Qualified Performance-Based Awards) of such Participant shall be considered to be earned and payable in full, any vesting conditions shall be considered to have been satisfied, and such restricted stock units and
performance units shall be settled in cash as promptly as is practicable. 
  

 -31- 

 11.6 Code Section 409A. Notwithstanding the foregoing, if any Award is subject to
Section 409A of the Code, this Section 11 shall be applicable only to the extent specifically provided in the agreement under Section 2.5 applicable to the Award and permitted pursuant to Section 12.2. 
 11.7 Other Agreements. Notwithstanding anything in this Plan to the contrary, to the extent that a Participant is a party to an agreement with the
Corporation (such as an employment agreement) that has change in control provisions which provide for the acceleration of equity awards owned by the Participant, the provisions of such agreement and not the provisions herein shall control the
acceleration and exercisability of such Participant’s equity awards. 
 SECTION 12 
 Qualified Performance-Based Awards; Section 409A 
 12.1 Qualified Performance-Based Awards. 
 (a) The provisions of this Plan are
intended to ensure that all options and stock appreciation rights granted hereunder to any Participant who is or may be a Covered Employee in the tax year in which such option or stock appreciation right is expected to be deductible to the
Corporation qualify for the exemption from the limitation on deductions imposed by Section 162(m) of the Code (the “Section 162(m) Exemption”), and all such Awards shall therefore be considered Qualified Performance-Based Awards
and this Plan shall be interpreted and operated consistent with that intention. When granting any Award other than an option or stock appreciation right, the Committee may designate such Award as a Qualified Performance-Based Award, based upon a
determination that (i) the recipient is or may be a Covered Employee with respect to such Award, and (ii) the Committee wishes such Award to qualify for the Section 162(m) Exemption, and the terms of any such Award (and of the grant
thereof) shall be consistent with such designation. Within 90 days after the commencement of a performance period or, if earlier, by the 

  

 -32- 

 
expiration of 25% of a performance period, the Committee will designate one or more performance periods, determine the Participants for the performance
periods and establish the Performance Goals for the performance periods. 
 (b) Each Qualified Performance-Based Award (other
than an option or stock appreciation right) shall be earned, vested and/or payable (as applicable) upon certification in writing by the Committee of the achievement of one or more Performance Goals, together with the satisfaction of any other
conditions, such as continued employment, as previously established by the Committee with respect to such Award. 
 (c)
Notwithstanding any provision in the Plan or in any agreement under Section 2.5, to the extent that any such provision or action of the Committee would cause any Qualified Performance-Based Award not to qualify for the Section 162(m)
Exemption, such provision or action shall be null and void as it relates to Covered Employees, to the extent permitted by law and deemed advisable by the Committee. 
 12.2 Code Section 409A. It is the intention of the Corporation that no Award shall be “deferred compensation” subject to Section 409A of the Code, unless and to the extent that the Committee
specifically determines otherwise as provided in the immediately following sentence, and the Plan and the terms and conditions of all Awards shall be interpreted accordingly. The terms and conditions governing any Awards that the Committee
determines will be subject to Section 409A of the Code, including any rules for elective or mandatory deferral of the delivery of cash or shares of Common Stock pursuant thereto and any rules regarding treatment of such Awards in the event of a
Section 11 Event, shall be set forth in the applicable agreement under Section 2.5, and shall comply in all respects with Section 409A of the Code. 
 SECTION 13 
 Effect of the Plan on the Rights of Participants 
 Neither the adoption of the Plan nor any action of the Board or the Committee pursuant to the Plan shall be deemed to 

  

 -33- 

 
give any Participant any right to be granted any Award under the Plan. Nothing in the Plan, in any Award under the Plan or in any agreement under
Section 2.5 providing for any Award under the Plan shall confer any right to any Participant to continue in the employ or service of the Corporation or any Subsidiary or interfere in any way with the rights of the Corporation or any Subsidiary
or shareholders to terminate the employment or service of such Participant at any time or adjust his or her compensation at any time. 
 SECTION 14 
 Amendment or Termination 
 The right to amend the Plan at any time and from time to time and the right to terminate the Plan are hereby specifically reserved to the Board; provided
that no such amendment of the Plan shall, without shareholder approval (a) increase the maximum aggregate number of shares of Common Stock for which Awards may be made under Section 4.1 of the Plan, (b) increase the maximum aggregate
number of shares of Common Stock as to which incentive stock options may be granted under Section 4.1 of the Plan, (c) make any changes in the class of Participants eligible to receive Awards under the Plan, (d) change the maximum
number of shares of Common Stock as to which Awards may be made to any Participant under Section 4.2 of the Plan, or the maximum amount that may be paid or distributed to any Participant pursuant to a grant of performance units or other
stock-based Awards made in any one calendar year under Section 8 or 9 of the Plan, respectively, (e) change the exercise price or Base Price permitted under Section 5.3 of the Plan or the restrictions regarding repricing under
Section 5.3 of the Plan,(f) be made if shareholder approval of the amendment is at the time required for Awards under the Plan to qualify for the exemption from Section 16(b) of the Exchange Act provided by Rule 16b-3 or by the rules of
the New York Stock Exchange or any stock exchange on which the Common Stock may then be listed or (g) be made to the extent such approval is needed for Qualified Performance-Based Awards to qualify for the Section 162(m) Exemption. No
amendment or termination of the Plan shall, without the written consent of the holder of an Award under the Plan, adversely affect the rights of such holder with respect thereto. 
  

 -34- 

 SECTION 15 
 General Provisions 
 15.1 Additional Compensation Arrangements. Nothing contained in the Plan
shall prevent the Corporation or any Subsidiary from adopting other or additional compensation arrangements for its Participants. 
 15.2
Tax Withholding. No later than the date as of which an amount first becomes includible in the gross income of a Participant for federal, state, local or foreign income or employment or other tax purposes with respect to any Award under the
Plan, such Participant shall pay to the Corporation (or, if applicable, a Subsidiary), or make arrangements satisfactory to the Corporation (or, if applicable, a Subsidiary) regarding the payment of, any federal, state, local or foreign taxes of any
kind required by law to be withheld with respect to such amount. Unless otherwise determined by the Committee, withholding obligations may be settled with Common Stock, including Common Stock that is part of the Award that gives rise to the
withholding requirement, having a Fair Market Value on the date of withholding equal to the minimum amount (and not any greater amount unless otherwise determined by the Committee) required to be withheld for tax purposes, all in accordance with
such procedures as the Committee establishes, and provided that any fractional share amount must be paid in cash or withheld from compensation otherwise due to the Participant. The obligations of the Corporation under the Plan shall be conditional
on such payment or arrangements, and the Corporation and its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment otherwise due to such Participant. The Committee may establish such procedures
as it deems appropriate, including making irrevocable elections, for the settlement of withholding obligations with Common Stock. 
 15.3
Limitation of Liability. The grant of any Award shall not: 
 (a) give a Participant any rights except as expressly set
forth in the Plan or in the agreement under Section 2.5; 
  

 -35- 

 (b) create any fiduciary or other obligation of the Corporation or any Subsidiary to take
any action or provide to the Participant any assistance or dedicate or permit the use of any assets of the Corporation or any Subsidiary that would permit the Participant to be able to attain any Performance Goals associated with any Award;

 (c) create any trust, fiduciary or other duty or obligation of the Corporation or any Subsidiary to engage in any
particular business, continue to engage in any particular business, engage in any particular business practices or sell any particular product or products; or 
 (d) create any obligation of the Corporation or any Subsidiary that shall be greater than the obligation of the Corporation or that
Subsidiary to any of their general unsecured creditors. 
 15.4 Limitation on Dividend Reinvestment and Dividend Equivalents.
Reinvestment of dividends in additional restricted stock at the time of any dividend payment, and the payment of shares with respect to dividends to Participants holding Awards of restricted stock units, shall only be permissible if authorized by
the Committee and if sufficient shares of Common Stock are available under Section 4 for such reinvestment or payment (taking into account then outstanding Awards). In the event that sufficient shares of Common Stock are not available for such
reinvestment or payment, such reinvestment or payment shall be made in the form of a grant of restricted stock units equal in number to the shares of Common Stock that would have been obtained by such payment or reinvestment, the terms of which
restricted stock units shall provide for settlement in cash and for dividend equivalent reinvestment in further restricted stock units on the terms contemplated by this Section 15.4. 
 15.5 Governing Law and Interpretation. To the extent not inconsistent with federal law, the Plan and all Awards made and actions taken thereunder
shall be governed by and construed in accordance with the laws of the Commonwealth of Pennsylvania, without reference to principles of conflict of laws. The captions of this Plan are not part of the provisions hereof and shall have no force or
effect. 
  

 -36- 

 15.6 Dispute Resolution. Since Awards are granted in Western Pennsylvania, records relating to the
Plan and Awards are located in Western Pennsylvania, and the Plan and Awards are administered in Western Pennsylvania, the Corporation and the Participant to whom an Award is granted, for themselves and their heirs, representatives, successors and
assigns (collectively, the “Parties”) irrevocably submit to the exclusive and sole jurisdiction and venue of the state courts of Allegheny County, Pennsylvania and the federal courts of the Western District of Pennsylvania with respect to
any and all disputes arising out of or relating to the Plan, the subject matter of the Plan or any Awards under the Plan, including but not limited to any disputes arising out of or relating to the interpretation and enforceability of any Awards or
the terms and conditions of the Plan. To achieve certainty regarding the appropriate forum in which to prosecute and defend actions arising out of or relating to the Plan, and to ensure consistency in application and interpretation of the governing
law under Section 15.5 of the Plan, the Parties agree that (a) sole and exclusive appropriate venue for any such action shall be the Pennsylvania courts described in the immediately preceding sentence, and no other, (b) all claims
with respect to any such action shall be heard and determined exclusively in such Pennsylvania courts, and no other, (c) such Pennsylvania courts shall have sole and exclusive jurisdiction over the Parties and over the subject matter of any
dispute relating hereto and (d) the Parties waive any and all objections and defenses to bringing any such action before such Pennsylvania courts, including but not limited to those relating to lack of personal jurisdiction, improper venue or
forum non conveniens. 
 15.7 Non-Transferability. Except as otherwise specifically provided in the Plan or by the Committee
and limited to a transfer without the payment of value or consideration to the Participant, Awards under the Plan are not transferable except by will or by laws of descent and distribution of the state of domicile of the Participant at the time of
death. 
 15.8 Deferrals. The Committee shall be authorized to establish procedures pursuant to which the payment of any Award may be
deferred, provided that any such deferral is consistent with all aspects of Section 409A of the Code. Subject to the provisions of this Plan and any agreement under Section 2.5, the recipient of an Award (including, without limitation, any
deferred Award) may, if so determined by the Committee, be 

  

 -37- 

 
entitled to receive, currently or on a deferred basis, interest or dividends, or interest or dividend equivalents, with respect to the number of shares
covered by the Award, as determined by the Committee, in its sole discretion, and the Committee may provide that such amounts (if any) shall be deemed to have been reinvested in additional shares or otherwise reinvested. 
 15.9 Integration. The Plan and any written agreements executed by Participants and the Corporation under Section 2.5 contain all of the
understandings and representations between the parties and supersede any prior understandings and agreements entered into between them regarding the subject matter within. There are no representations, agreements, arrangements or understandings,
oral or written, between the parties relating to the subject matter of the Plan which are not fully expressed in the Plan and the written agreements. 
 15.10 Foreign Employees and Foreign Law Considerations. The Committee may grant Awards to eligible employees who are foreign nationals, who are located outside the United States of America or who are not
compensated from a payroll maintained in the United States of America, or who are otherwise subject to (or could cause the Corporation to be subject to) legal or regulatory provisions of countries or jurisdictions outside the United States of
America, on such terms and conditions different from those specified in the Plan as may, in the judgment of the Committee, be necessary or desirable to foster and promote achievement of the purposes of the Plan, and, in furtherance of such purposes,
the Committee may make such modifications, amendments, procedures, or subplans as may be necessary or advisable to comply with such legal or regulatory provisions. 
 SECTION 16 
 Effective Date and Duration of Plan 
 The effective date and date of adoption of the Plan shall be March 25, 2008, the date of adoption of the Plan by the Board, provided that the Plan
is approved by a majority of the votes cast at a meeting of shareholders duly called, convened and held on or prior to March 25, 2009, at which a quorom representing a majority of the outstanding voting stock of the Corporation is, either in
person or by proxy, present and voting on the Plan. No stock option or stock appreciation right 

  

 -38- 

 
granted under the Plan on or after March 25, 2008 may be exercised until after such approval and any restricted stock, restricted stock units,
performance units or other Award awarded under the Plan shall be forfeited to the Corporation on March 25, 2009 if such approval has not been obtained on or prior to that date. No Award under the Plan may be made subsequent to March 25,
2018.
