Goldenbridge Acquisition Limited

15/F, Aubin House

171-172 Gloucester Road

Wanchai, Hong Kong

 

Ladies and Gentlemen:

 

Goldenbridge Acquisition Limited (the “Company”),
a blank check company formed for the purpose of acquiring one or more businesses or entities (a “Business Combination”),
intends to register its securities under the Securities Act of 1933, as amended (“Securities Act”), in connection with
its initial public offering (“IPO”), pursuant to a registration statement on Form S-1 (“Registration Statement”).

 

The undersigned hereby commits that it will
purchase 350,000 units of the Company (“Private Units”), each Private Unit consisting of one ordinary share of the
Company, no par (the “Ordinary Shares”), one warrant (the “Warrants”) entitling its holder to purchase
one-half (1/2) of one Ordinary Share, and one right to receive one-tenth (1/10) of an Ordinary Share (each a “Right”),
at $10.00 per Private Unit, for a purchase price of $3,500,000 (the “Private Unit Purchase Price”).

 

At least twenty-four (24) hours prior to the
effective date of the Registration Statement, the undersigned will cause the Private Unit Purchase Price to be delivered to Loeb
& Loeb LLP (“Loeb”), counsel for the Company, by wire transfer as set forth in the instructions attached as Exhibit
A to hold in a non-interest bearing account until the Company consummates the IPO.

 

The consummation of the purchase and issuance
of the Private Units shall occur simultaneously with the consummation of the IPO. Simultaneously with the consummation of the IPO,
Loeb shall deposit the Private Unit Purchase Price, without interest or deduction, into the trust fund (“Trust Fund”)
established by the Company for the benefit of the Company’s public shareholders as described in the Registration Statement.
If the Company does not complete the IPO within ten (10) days from the date of this letter, the Private Unit Purchase Price (without
interest or deduction) will be returned to the undersigned.

 

Each of the Company, and the undersigned acknowledges
and agrees that Loeb is serving hereunder solely as a convenience to the parties to facilitate the purchase of the Private Units
and Loeb’s sole obligation under this letter agreement is to act with respect to holding and disbursing the Private Unit
Purchase Price as described above. Loeb shall not be liable to the Company, Maxim or the undersigned or any other person or entity
in respect of any act or failure to act hereunder or otherwise in connection with performing its services hereunder unless Loeb
has acted in a manner constituting gross negligence or willful misconduct. The Company and the undersigned shall indemnify Loeb
against any claim made against it (including reasonable attorney’s fees) by reason of it acting or failing to act in connection
with this letter agreement except as a result of its gross negligence or willful misconduct. Loeb may rely and shall be protected
in acting or refraining from acting upon any written notice, instruction or request furnished to it hereunder and believed by it
to be genuine and to have been signed or presented by the proper party or parties.

 

The Private Units will be identical to the
units to be sold by the Company in the IPO. Additionally, the undersigned agrees:

 

		●	to vote the Ordinary Shares included in the Private Units in favor of any proposed Business Combination;

 

		●	not to propose, or vote in favor of, an amendment to the Company’s Amended and Restated Memorandum and Articles of Association
that would affect the substance or timing of the Company’s obligation to redeem 100% of the Company’s Ordinary Shares
sold in the IPO if the Company does not complete an initial Business Combination within 12 months from the closing of the IPO (or
up to 21 months, as applicable), unless the Company provides the holders of Ordinary Shares sold in the IPO with the opportunity
to redeem their Ordinary Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate
amount of the Trust Fund, including interest earned on Trust Fund and not previously released to the Company to pay the Company’s
franchise and income taxes, divided by the number of then outstanding Ordinary Shares sold in the IPO;

 

    

     

    

 

		●	not to convert any Ordinary Shares included in the Private Units into the right to receive cash from the Trust Fund in connection
with a shareholder vote to approve either a Business Combination or an amendment to the provisions of the Company’s Amended
and Restated Memorandum and Articles of Association, and not to tender the Private Units in connection with a tender offer conducted
prior to the closing of a Business Combination;

 

		●	the undersigned will not participate in any liquidation distribution with respect to the Private Units (but will participate
in liquidation distributions with respect to any units or Ordinary Shares purchased by the undersigned in the IPO or in the open
market) if the Company fails to consummate a Business Combination;

 

		●	that the Private Units and underlying securities will not be transferable until after the consummation of a Business Combination
except (i) to the Company’s pre-IPO shareholders, or to the Company’s officers, directors, advisors and employees,
(ii) transfers to the undersigned’s affiliates or its members upon its liquidation, (iii) to relatives and trusts for estate
planning purposes, (iv) by virtue of the laws of descent and distribution upon death, (v) pursuant to a qualified domestic relations
order, (vi) by private sales made in connection with the consummation of a Business Combination at prices no greater than the price
at which the Private Units were originally purchased or (vii) to the Company for cancellation in connection with the consummation
of a Business Combination, in each case (except for clause vii) where the transferee agrees to the terms of the transfer restrictions;
and

 

		●	the Private Units will include any additional terms or restrictions as is customary in other similarly structured blank check
company offerings or as may be reasonably required by the underwriters in the IPO in order to consummate the IPO, each of which
will be set forth in the Registration Statement.

 

The undersigned acknowledges and agrees that
the purchaser of the Private Units will execute agreements in form and substance typical for transactions of this nature necessary
to effectuate the foregoing agreements and obligations prior to the consummation of the IPO as are reasonably acceptable to the
undersigned, including but not limited to an insider letter.

 

The undersigned hereby represents and warrants
that:

 

		(a)	it has been advised that the Private Units have not been registered under the Securities Act;

 

		(b)	it will be acquiring the Private Units for its account for investment purposes only;

 

		(c)	it has no present intention of selling or otherwise disposing of the Private Units in violation of the securities laws of the
United States;

 

		(d)	it is an “accredited investor” as defined by Rule 501 of Regulation D promulgated under the Securities Act of 1933,
as amended;

 

		(e)	it has had both the opportunity to ask questions and receive answers from the officers and directors of the Company and all
persons acting on its behalf concerning the terms and conditions of the offer made hereunder;

 

    2

     

    

 

		(f)	it is familiar with the proposed business, management, financial condition and affairs of the Company;

 

		(g)	it has full power, authority and legal capacity to execute and deliver this letter and any documents contemplated herein or
needed to consummate the transactions contemplated in this letter; and

 

		(h)	this letter constitutes its legal, valid and binding obligation, and is enforceable against it.

 

This letter agreement constitutes the entire agreement between
the undersigned and the Company with respect to the purchase of the Private Units, and supersedes all prior and contemporaneous
understandings, agreements, representations and warranties, both written and oral, with respect to the same.

 

	 	Very truly yours,

    WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATION

     

    2011 STOCK INCENTIVE PLAN

     

    (as amended and restated effective May 15, 2020)

    (as amended by Amendment Number One dated January 14, 2021)

     

    SECTION 1

    PURPOSE; DEFINITIONS

     

    1.1       Purpose. The purposes of the 2011 Stock Incentive Plan, as amended and restated effective May 15, 2020 (the “Plan”), are to encourage eligible employees of Westinghouse Air Brake
          Technologies Corporation (the “Corporation”) and its Subsidiaries to increase their efforts to make the Corporation and each Subsidiary more successful, to provide an additional inducement for such employees to remain with the Corporation or a
          Subsidiary, to reward such employees by providing an opportunity to acquire shares of Common Stock on favorable terms and to provide a means through which the Corporation may attract able persons to enter the employ of the Corporation or one of
          its Subsidiaries.

     

    1.2        Certain Definitions. In addition to terms defined herein in a 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)          “Common Stock”
          shall mean the Common Stock, par value $0.01 per share, of the Corporation.

     

    (d)         “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 such 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 NASDAQ Exchange or the principal United States of America securities
          exchange registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”) on which the Common Stock is listed. 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 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 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.

     

        

    
      
        

    

    (e)          “Free-Standing
          SARs” shall have the meaning set forth in Section 5.2.

     

    (f)          “Participant” means
          an eligible employee selected by the Committee who has received an Award under the Plan and any transferee or transferees of such employee to the extent the transfer is permitted under the Plan.

     

    (g)         “Performance Goals”
          means the performance goals, if any, established by the Committee in connection with the grant of restricted stock, restricted stock units, performance units or other Awards. In the case of Qualified Performance-Based Awards, the “Performance
          Goals” means such performance goals based on one or more of the following: (i) cash flow; (ii) earnings per share; (iii) earnings or income measures (including EBIT and EBITDA)); (iv) return measures (including return on assets, capital, invested
          capital, equity, sales, or revenue); (v) total shareholder return; (vi) share price performance; (vii) revenue; (viii) profit margin; (ix) customer metrics (including customer satisfaction, customer retention, or customer profitability); (x)
          productivity; (xi) expense targets; (xii) market share; (xiii) cost control measures; (xiv) balance sheet metrics; (xv) strategic initiatives; (xvi) implementation,
            completion or attainment of measurable objectives with respect to recruitment or retention of personnel, employee satisfaction or diversity; (xvii) successful completion of, or achievement of milestones or objectives related to, financing or
            capital raising transactions, strategic acquisitions or divestitures, joint ventures, partnerships, collaborations, or other transactions; (xviii) debt levels or reduction or debt ratios; (xix) operating efficiency; (xx) working capital
            targets; (xxi) quantifiable, objective measures of individual performance relevant to the particular individual’s job responsibilities; (xxii) environmental missions improvement; (xxiii) innovation as measured by a percentage of sales from new
            products; (xxiv) safety performance; (xxv) number of accounts; or (xvi) any combination of the forgoing business criteria; provided, however, that such business criteria shall include any derivations of business criteria listed above (e.g., income shall include pre-tax income, net income, or operating income). Any business criteria that are
            financial metrics may be determined in accordance with United States Generally Accepted Accounting Principles (“GAAP”) or may be adjusted when established (or to the extent permitted under Section 162(m), at any time thereafter) to include or
            exclude any items otherwise includable or excludable under GAAP. Performance Goals may, in the discretion of the Committee, be established on a Company-wide basis, or with respect to one or more business units, divisions, subsidiaries or
            business segments, as applicable. Performance Goals may be absolute or relative (to the performance of one or more comparable companies or indices or based on year- over-year growth).

     

          

    
      
        

    

    (h)          “Qualified
          Performance-Based Award” means an Award intended to qualify for the Section 162(m) Exemption, as provided in Section 12.

     

    (i)         “Subsidiary” means
          any corporation, partnership, joint venture, limited liability company or other entity in an unbroken chain of entities beginning with the Corporation if each of the entities other than the last entity in the unbroken chain owns an equity
          interest possessing at least fifty percent (50%) or more of the total combined voting power of all classes of stock in one of the other entities in the chain.

     

    (j)           “Tandem SARs”
          shall have the meaning set forth in Section 5.2.

     

    SECTION 2

    ADMINISTRATION

     

    2.1       Committee. The Plan shall be administered by a Committee (the “Committee”) appointed by the Board of Directors of the Corporation (the “Board”) and consisting of not less than two
          members of the Board, who, at the time of their appointment to the Committee and at all times during their service as members of the Committee, are (a) “Non-Employee Directors” as then defined under Rule 16b-3 under the 1934 Act, or any successor
          rule, (b) “outside directors” under Section 162(m)(4)(C) of the Internal Revenue Code of 1986 as amended (the “Code”) or any successor provision, and (c) independent directors under the applicable rules of any applicable stock exchange, if the
          Common Stock is subject to such rules. The Committee shall have plenary authority to interpret the Plan and prescribe such rules, regulations and procedures in connection with the operations of the Plan as it shall deem to be necessary and
          advisable for the administration of the Plan consistent with the purposes of the Plan. Without limitation of the foregoing, the Committee shall have the authority, subject to the terms and conditions of the Plan:

     

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

     

    (b)       to determine whether
          and to what extent incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, other Awards of or based upon Common Stock, or any combination thereof, are to be
          granted hereunder;

     

    (c)          to determine the
          number of shares of Common Stock to be covered by each Award made hereunder;

     

    (d)       to determine the
          terms and conditions of each Award made hereunder, based on such factors as the Committee shall determine;

     

    (e)           subject to
          Section 2.5, to modify, amend or adjust the terms and conditions of any Award;

     

    (f)          to adopt, alter and
          repeal such administrative rules, guidelines and practices governing the Plan as it shall from time to time deem advisable;

     

    (g)         to interpret the
          terms and provisions of the Plan and any Award under the Plan (and any agreement under Section 2.5 relating thereto);

     

        

    
      
        

    

    (h)         subject to Section
          2.5, 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;

     

    (i)           to decide all
          other matters that must be determined in connection with an Award;

     

    (j)          to determine
          whether, to what extent and under what circumstances cash, shares of Common Stock and other property and other amounts payable with respect to an Award under this Plan shall be deferred either automatically or at the election of the employee;

     

    (k)          to establish any
          “blackout” period that the Committee in its sole discretion deems necessary or advisable; and

     

    (l)           to otherwise
          administer the Plan.

     

    In determining any Award to be made to any eligible employee, the Committee shall consider the position and the 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”) or persons subject to Section 16 of the 1934 Act.

     

    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 employees eligible under the Plan. No member of the Committee shall be liable for any action or
          determination made in good faith with respect to the Plan, any Award or Award agreement.

     

        

    
      
        

    

    2.4        Cancellation; Suspension; Clawback. Any or all outstanding Awards to a Participant may, at any time between the date of grant and the third anniversary of any exercise, payment or
          vesting of such Awards, 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 to the Corporation if, to the extent permitted by applicable law,
          the Participant (whether during or after termination of employment 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 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. 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. In addition, Awards shall be subject to the requirements
          of (i) Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (regarding recovery of erroneously awarded compensation) and any implementing rules and regulations thereunder, (ii) similar rules under the laws of any other
          jurisdiction, (iii) any compensation recovery policies adopted by the Company to implement any such requirements or (iv) any other compensation recovery policies as may be adopted from time to time by the Company, all to the extent determined by
          the Committee in its discretion to be applicable to a Participant.

     

    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 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        Minimum Vesting Requirements.  Notwithstanding any other provision of the Plan to the contrary, share-settled Awards granted under the Plan shall vest no earlier than the first
          anniversary of the date the Award is granted, excluding, for this purpose, any (i) substitute awards, and (ii) shares delivered in lieu of fully vested cash compensation; provided, that, the Board may grant share-settled Awards without regard to
          the foregoing minimum vesting requirement with respect to a maximum of five percent (5%) of the available share reserve authorized for issuance under the Plan pursuant to Section 4.1 (subject to adjustment under Section 4.5); and, provided
          further, for the avoidance of doubt, that the foregoing restriction does not apply to the Committee’s discretion to provide for accelerated exercisability or vesting of any Award, including in cases of retirement, death, disability or a Section
          11 Event, in the terms of the Award or otherwise.1

    
      

      

      
        

      

      1 Section 2.6 was added by Amendment Number One to the Plan dated January 14, 2021.

       

      

    

     
    
      
        

    

    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 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.

     

    

    SECTION 4

          effective date of this Plan (also after giving effect to the 2-for-1 stock split in the form of a stock dividend in June 2013), plus (iii) effective as of May 10, 2017, an additional 1,000,000 shares, plus (iv) effective as of May 15, 2020 upon

          calendar year shall not exceed the following number of shares of Common Stock: (i) options and stock appreciation rights: 600,000 shares; and (ii) all Awards of restricted stock, restricted stock units, share-based performance units and other
          stock-based awards that are intended to be Qualified Performance-Based Awards: 600,000 shares. The maximum amount of cash-based performance unit Awards intended to be Qualified Performance-Based Awards granted to any Participant in any calendar
          year shall not exceed the following: (x) any cash-based performance unit Award with a performance period that is the Company’s fiscal year or other 12-month (or shorter) performance period as specified under the terms of the Award as approved by
          the Committee (an “annual incentive award”): $5,000,000; and (y) all other cash-based performance unit Awards: $5,000,000.

     

        

    
      
        

    

    4.3         Share Counting.

     

    (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 settled for cash, the shares of Common Stock subject 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.

     

    (b)          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.
          Shares of Common Stock that the Company may repurchase from time to time with proceeds from the exercise of options or otherwise shall not be added to the aggregate number of shares under Section 4.1 for which Awards may be made under the Plan.

     

    (c)         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.

     

    (d)          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.

     

    (e)         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.

     

    (f)          Awards granted in
          assumption of or in substitution for an award of a company or business acquired by the Company or a Subsidiary or with which the Company or a Subsidiary combines (“substitute awards”) shall not be counted against the number of shares reserved
          under the Plan.

     

    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, acquisition of shares, 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”), 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 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 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 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. Except as provided in this Section 4.5, a Participant shall not have any rights with respect to any Corporate Transaction or Share Change.

     

          

    
      
        

    

    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 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. 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 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.

     

    5.3         Exercise Price and Base Price.

     

    (a)          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 not be 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 Employee”), the exercise price shall not be 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.

     

    (b)        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 term 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 Employee). Except as otherwise provided herein, options and stock appreciation rights shall be 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 during the applicable term 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 by certified or bank check or wire of immediately available funds. 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;

     

    (c)          To the extent
          permitted by applicable law and if authorized by the Corporation, payment may be made by a “net exercise” by the Corporation withholding shares of Common Stock otherwise due to the Participant upon exercise; and/or

     

    (d)       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 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
          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 or a Participant retires under any retirement plan
          of the Corporation or a Subsidiary, any then outstanding incentive stock option 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 of
          a Participant who is not a Disabled Participant is voluntarily terminated with the consent of the Corporation or a Subsidiary or a Participant retires under any retirement plan 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 of
          a Participant who is a Disabled Participant is voluntarily terminated with the consent of the Corporation or a Subsidiary, 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 during employment, 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;

     

    (e)       Following the death
          of a Participant after termination of employment during a period when a stock option or stock appreciation right is exercisable, any outstanding stock option or stock appreciation right held by the Participant at the time of death shall be
          exercisable by such person entitled to do so under the will of the Participant or by such legal representative (but only to the extent the stock option or stock appreciation right was exercisable by the Participant immediately prior to the death
          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

     

    (f)        Unless the exercise
          period of a stock option or stock appreciation right following termination of employment has been extended as provided in Section 11.3, if the employment 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 shall automatically terminate.

     

    Whether termination of employment is a voluntary termination with the consent of the Corporation or a Subsidiary 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 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 in writing.

     

    5.9        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.

     

        

    
      
        

    

    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 Westinghouse Air Brake Technologies Corporation 2011 Stock Incentive Plan and a corresponding agreement. Copies of such Plan and agreement are on file at the offices of Westinghouse Air Brake Technologies
      Corporation, 1001 Air Brake Avenue, Wilmerding, PA 15148.”

     

    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)        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 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 the 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 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 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)         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 Award. 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.

     

    (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 employees, 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. Performance units may be share-based or cash-based, including annual incentive awards. 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 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. Except in the case of a Qualified Performance- Based Award, the Committee at any time after the grant of performance units,
      in its sole discretion, may modify or waive any of the conditions applicable to an Award of performance units.

     

    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.

     

    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.

     

    For purposes of this Section 11, the following terms shall have the following meanings:

     

    (1)         The term “Person”
          shall be used as that term is used in Sections 13(d) and 14(d) of the 1934 Act as in effect on the effective date of the Plan.

     

    (2)        “Beneficial
          Ownership” shall be determined as provided in Rule 13d-3 under the 1934 Act as in effect on the effective date of the Plan.

     

    (3)        A specified
          percentage of “Voting Power” of a company shall mean such number of the Voting Shares as shall enable the holders thereof to cast such percentage of all the votes which could be cast in an annual election of directors (without consideration of
          the rights of any class of stock other than the common stock of the company to elect directors by a separate class vote); and “Voting Shares” shall mean all securities of a company entitling the holders thereof to vote in an annual election of
          directors (without consideration of the rights of any class of stock other than the common stock of the company to elect directors by a separate class vote).

     

    (4)         “Continuing
          Directors” shall mean a director of the Corporation who either (a) was a director of the Corporation on the effective date of the Plan or (b) is an individual whose election, or nomination for election, as a director of the Corporation was
          approved by a vote of at least two-thirds of the directors then still in office who were Continuing Directors (other than an individual whose initial assumption of office is in connection with an actual or threatened election contest relating to
          the election of directors of the Corporation which would be subject to Rule 14a-11 under the 1934 Act, or any successor rule).

     

    (5)          “Section 11 Event”
          shall mean the date upon which any of the following events occurs:

     

    (a)        The Corporation
          acquires actual knowledge that any Person, other than the Corporation, a Subsidiary, or any employee benefit plan(s) sponsored by the Corporation or a Subsidiary, has acquired the Beneficial Ownership, directly or indirectly, of securities of the
          Corporation entitling such Person to 30% or more of the Voting Power of the Corporation;

     

    (b)          At any time less
          than 51% of the members of the Board (excluding vacant seats) shall be Continuing Directors; or

     

    (c)       The consummation of a
          merger, consolidation, share exchange, division or sale or other disposition of assets of the Corporation as a result of which the stockholders of the Corporation immediately prior to such transaction shall not hold, directly or indirectly,
          immediately following such transaction a majority of the Voting Power of (i) in the case of a merger or consolidation, the surviving or resulting corporation, (ii) in the case of a share exchange, the acquiring corporation or (iii) in the case of
          a division or a sale or other disposition of assets, each surviving, resulting or acquiring corporation which, immediately following the transaction, holds more than 30% of the consolidated assets of the Corporation immediately prior to the
          transaction; provided, however, that if securities beneficially owned by a Participant are included in
          determining the Beneficial Ownership of a Person referred to in paragraph 6(a) above, then no Section 11 Event with respect to such Participant shall be deemed to have occurred by reason of such event.

     

        

    
      
        

    

    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 Section 11.6,
          unless the agreement under Section 2.5 shall otherwise provide, notwithstanding any other provision contained in the Plan, in case any Section 11 Event occurs all outstanding stock options and stock appreciation rights (other than those held by a
          Participant referred to in the proviso to Section 11.1(6)) 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, notwithstanding any other provision contained in the Plan, all stock options and stock appreciation rights held by a Participant (other than a Participant referred to in the proviso
          to Section 11.1(6)) whose employment with the Corporation or a Subsidiary terminates within one year of any Section 11 Event 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 shall be exercisable for a period of three years 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, notwithstanding any other provision contained in the Plan other
          than Section 11.6, if any Section 11 Event occurs prior to the scheduled lapse of all restrictions applicable to restricted stock Awards under the Plan (including but not limited to Qualified Performance-Based Awards), all such restrictions
          (other than those applicable to a Participant referred to in the proviso to Section 11.1(6)) shall lapse upon the occurrence of any such Section 11 Event 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, notwithstanding any other provision contained in the Plan
          other than Section 11.6, if any Section 11 Event occurs, all restricted stock units and performance units (including but not limited to Qualified Performance-Based Awards) (other than those held by a Participant referred to in the proviso to
          Section 11.1(6)) 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
          after the Section 11 Event.

     

    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.

     

        

    
      
        

    

    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. With respect to Qualified Performance-Based Awards, within 90 days after the commencement of a performance period or, if earlier, by the 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. Subject to the terms of any applicable Award agreement, the Committee may, in its discretion, reduce
          (but not increase) the amount of a settlement otherwise to be made in connection with a Qualified Performance- Based 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 EMPLOYEES AND EMPLOYER

     

    Neither the adoption of the Plan nor any action of the Board or the Committee pursuant to the Plan shall be deemed to give any employee
      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 employee to continue in the employ of the
      Corporation or any Subsidiary or interfere in any way with the rights of the Corporation or any Subsidiary to terminate the employment of any employee at any time or adjust the compensation of any employee 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 employees 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 1934 Act provided by Rule 16b-3 or by the rules of 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.

     

    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 employees.

     

    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 maximum amount 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;

     

    (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 preempted by 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.

     

        

    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 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; provided, however, that in no event shall interest, dividends or dividend equivalents be paid on any unearned performance
          units or performance share units until such units have vested.

     

    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.
