(i) no Stockholder shall Transfer any Stockholder Shares to any Person unless such Transfer is done in accordance with applicable Law, including, but not limited to, the Securities Act, and (ii) each Stockholder that is an entity that was
formed for the purpose of directly or indirectly acquiring Stockholder Shares or that has no substantial assets other than Stockholder Shares or direct or indirect interests in Stockholder Shares acknowledges and agrees that (x) certificates

	2.2	Co-Sale Rights. 

 (a) If at any time a CCMP Investor proposes to sell, Transfer or
assign any of its Stockholder Shares (other than to a member of such CCMP Investors’ Group), then at least thirty (30) days prior to the closing of such proposed transaction, such CCMP Investor shall deliver a written notice (the
“Co-Sale Notice”) to all Other Stockholders offering such Other Stockholders the option to participate in such proposed transaction. Such Co-Sale Notice shall specify in reasonable detail the identity of the prospective Transferee,
the number and class(es) of Stockholder Shares proposed to be Transferred, the proposed purchase price for such Stockholder Shares and all other terms and conditions material to the proposed sale. 

(b) Any Other Stockholder may, within fifteen (15) days of the receipt of a Co-Sale Notice (the “Co-Sale Offer Period”),
give written notice (each, a “Tag-Along Notice”) to such CCMP Investor stating that such Other Stockholder wishes to participate in such proposed transaction and specifying the amount of Stockholder Shares such Stockholder desires
to include in such proposed transaction. Such Other Stockholder shall only include Stockholder Shares in the Tag-Along Notice of the same class, series or type (and in the same proportion) of Stockholder Shares being sold, Transferred or assigned by
such CCMP Investor. 
 (c) If no Other Stockholder gives such CCMP Investor a Tag-Along Notice within the Co-Sale Offer Period with respect
to the transaction proposed in the Co-Sale Notice, such CCMP Investor may thereafter consummate the transaction specified in the Co-Sale Notice on terms and conditions not more favorable to such CCMP Investor than as set forth in the Co-Sale Notice.
If one or more Other Stockholders give such CCMP Investor a Tag-Along Notice within the Co-Sale Offer Period, then such CCMP Investor shall use all reasonable efforts to cause the 

  
 -12- 

 
prospective Transferee(s) to agree to acquire all Stockholder Shares identified in all Tag-Along Notices that are timely given to such CCMP Investor, upon the same terms and conditions as
applicable to such CCMP Investor’s Stockholder Shares. If the prospective Transferee(s) are unwilling or unable to acquire all Stockholder Shares proposed to be included in such sale upon such terms, then such CCMP Investor shall either
(i) elect to cancel such proposed transaction or (ii) allocate the maximum number of Stockholder Shares that each prospective Transferee is willing to purchase among itself and the Other Stockholders giving Tag-Along Notices within the
Co-Sale Offer Period in proportion to each such Stockholder’s pro rata owned portion of the particular class, series or type of Stockholder Shares subject to this Section 2.2 (excluding for the purposes of such calculation, the
Stockholder Shares held by the Other Stockholders who have not delivered a timely Tag-Along Notice). 
  

	2.3	Required Sale in Connection with a Sale of the Company. 

 (a) Subject to the
provisions of Section 2.1 and this Section 2.3, if the CCMP Investors at any time propose that the Company consummate (or commit to consummate) a Liquidity Event (an “Approved Sale”), then each Stockholder
will agree to consent to and shall raise no objections against the Approved Sale. If the Approved Sale is structured as (i) a merger, recapitalization, consolidation of the Company, or a sale of all or substantially all of the Company’s
assets, then each Stockholder shall waive any dissenter’s rights, appraisal rights or similar rights in connection with such transaction and shall vote in favor of such Approved Sale, or (ii) a Transfer of the issued and outstanding
Stockholder Shares, each Stockholder will, and hereby agrees to, Transfer his, her or its Stockholder Shares on the terms and conditions approved by the CCMP Investors (in proportion to such Stockholder’s pro rata owned portion of the
particular class, series or type of Stockholder Shares, on a fully diluted basis, subject to this Section 2.3, if such Approved Sale involves less than 100% of all such issued and outstanding Stockholder Shares (the
“Stockholder’s Sale Requirement”)). In each such Approved Sale, the value to be received by the Stockholders shall be allocated among the Stockholders as if the Company was being liquidated and its assets were being distributed
in accordance with the Certificate; provided, that any liabilities of the Company shall not be entitled to be satisfied more than once. All Stockholders and the Company shall cooperate fully and in good faith in connection with the conduct of
the sale process and the consummation of the Approved Sale and agree to execute such agreements and instruments and take actions reasonably necessary to provide the representations, warranties, indemnities, covenants, conditions, escrow agreements
and other provisions and agreements relating to such Approved Sale that are agreed to by the CCMP Investors (with the CCMP Investors being subject to the same terms on a per share basis for the same classes of shares that are owned by the Other
Stockholders and being made subject to this Section 2.3) and to obtain all governmental and third-party approvals and consents reasonably necessary or desirable to consummate such Approved Sale. Additionally, the Company agrees to, and
to cause the Company Group Employees to, use its and their reasonable best efforts to facilitate and support any due diligence process being undertaken in connection with such Approved Sale. In connection with this Section 2.3, each
Stockholder that holds Common Stock Equivalents, which are either vested or will vest in connection with the Approved Sale, with an underlying fair market value that exceeds the applicable exercise or conversion price, as the case may be, shall be
obligated to exercise or convert all such Common Stock Equivalents pursuant to the underlying agreements governing such Common Stock Equivalents prior to the consummation of the Approved Sale; provided, that such Stockholder

  
 -13- 

 
may, in lieu of exercising or converting such Common Stock Equivalents, elect to receive (x) the aggregate amount of consideration such Stockholder would have received in connection with the
Approved Sale had such Stockholder exercised or converted all such Common Stock Equivalents less (y) the aggregate exercise or conversion price of all such Common Stock Equivalents; provided, further, that such Stockholder
shall not be required to exercise or convert such Common Stock Equivalents if the CCMP Investors waive such Stockholder’s obligation to exercise or convert in writing, in which case such Stockholder shall continue to participate as a holder of
Securities. Notwithstanding the foregoing, if the Approved Sale is a Transfer of less than 100% of the issued and outstanding Stockholder Shares, each Stockholder will only be required to exercise or convert (i) a number of Common Stock
Equivalents as are necessary so that the Stockholder has sufficient Stockholder Shares to sell to meet his, her or its Stockholder’s Sale Requirement, or (ii) Common Stock Equivalents that are either vested or will vest in connection with
the Approved Sale, with an underlying fair market value that exceeds the applicable exercise or conversion price, as the case may be, if such Stockholder is able to sell the Stockholder Shares obtained upon such exercise or conversion for cash or
liquid Securities in such Approved Sale. 
 (b) The Company shall deliver written notice to each Stockholder setting forth in reasonable
detail the terms (including purchase price, timing and form of payment) of any Approved Sale (the “Approved Sale Notice”). Within fifteen (15) days following receipt of the Approved Sale Notice, each Stockholder shall deliver
to the Company written notice (in form and substance reasonably satisfactory to the CCMP Investors) setting forth such Stockholder’s agreement (i) to consent to and raise no objections against, or impediments to, the Approved Sale
(including, waiving all dissenter’s and similar rights) and (ii) if the Approved Sale is structured as a sale of stock, to sell its Stockholder Shares on the terms and conditions set forth in the Approved Sale Notice. 

(c) The obligations of the Stockholders to participate in any Approved Sale pursuant to this Section 2.3 are subject to the
satisfaction of the following conditions: 
 (i) if any Stockholder (other than any Management Stockholder) is given an
option as to the form and amount of consideration to be received with respect to Securities in a class, all holders of Securities and of such class will be given the same option; 

(ii) no Stockholder shall be required to make any representations and warranties other than with respect to ownership of its
Stockholder Shares, tax status, authority to enter into such Approved Sale, conflicts with Law or contracts, organizational documents applicable to such Stockholder, other representations and warranties customary for the type of party at issue and
the transaction being consummated, and representations and warranties with respect to any other matters particular to such Stockholder; 

(iii) in the event that the Stockholders are required to provide any indemnities (including indemnities for representations and
warranties made by the Company and its Subsidiaries in connection with a Liquidity Event), (A) no Stockholder shall be liable for more than its Pro Rata Amount of any such indemnification obligation and (B) any such

  
 -14- 

 
liability will not exceed the total purchase price received by such Stockholder (net of broker fees and the selling expenses described in Section 2.3(e)) from such purchaser for his,
her or its Stockholder Shares; and 
 (iv) the AIMCo Investor shall not be required to agree or enter in to any
non-competition agreement or covenant imposed on the AIMCo Investor in connection with such Approved Sale; provided, however, that if the CCMP Investors agree to or enter into any agreement or covenant not to solicit or hire any
employees of the Company or any of its Subsidiaries, the AIMCo Investor shall be required to enter into or agree to the same such employee non-solicitation or no hire agreement or covenant. 

(d) If the Company and any of the Stockholders or their Representatives enter into any negotiation or transaction for which Rule 506 under the
Securities Act (or any similar rule then in effect) may be available with respect to such negotiation or transaction (including a merger, consolidation or other reorganization), each Stockholder who is not an accredited investor (as such term is
defined in Rule 501 under the Securities Act) will, at the request of the Company, appoint a purchaser representative (as such term is defined in Rule 501 under the Securities Act) reasonably acceptable to the Company. 

(e) The reasonable costs and expenses incurred by or on behalf of a Stockholder in connection with a consummated Approved Sale shall be paid
by the Company or the acquiring Person. 
 (f) The restrictions on Transfers of Stockholder Shares set forth in Section 2.2
shall not apply in connection with any Transfer made pursuant to an Approved Sale. 
 (g) If any Other Stockholder is in breach of its
obligations under this Section 2.3, then, in addition to any other remedies available to the Company or any other Stockholder, the Company may execute, on behalf of such defaulting Other Stockholder, any agreement, instrument or waiver
executed by the non-defaulting Other Stockholders in connection with an Approved Sale. Each Other Stockholder (other than the AIMCo Investor) appoints the Company as his, her or its attorney-in-fact to carry out the intent of this
Section 2.3(g), and acknowledges that such power of attorney is coupled with an interest, cannot be terminated without the consent of the Company and is binding on all of such Other Stockholder’s Transferees of Stockholder Shares.
To the extent an Other Stockholder (other than the AIMCo Investor) fails to comply with the provisions of this Section 2.3, such Other Stockholder hereby indemnifies, defends and holds the Company harmless against all liability, loss or
damage, together with all reasonable costs and expenses (including reasonable legal fees and expenses), relating to or arising from its exercise of the power of attorney granted hereby. 

 

	2.4	Call Right. 

 (a) Notwithstanding anything to the contrary contained in any
employment or similar agreement entered into as of the Closing Date between the Company and/or any of its parent companies or Subsidiaries, or any Affiliates thereof, and a Management Stockholder (as the same may be amended, modified, supplemented
or restated from time to time, an “Existing Employment Agreement”), following the occurrence of a Repurchase Triggering Event with 

  
 -15- 

 
respect to such Management Stockholder, the Company shall have the right (but not the obligation) to repurchase from such Management Stockholder all or any portion of the Stockholder Shares owned
by such Management Stockholder. Any member of such Management Stockholder’s Group that holds Stockholder Shares (other than any such Person who is also an employee or director of the Company or any of its Subsidiaries and received such
Stockholder Shares in such capacity) shall be subject to this Section 2.4 as if such member of such Management Stockholder’s Group and such Management Stockholder are one and the same. For the avoidance of doubt and except as set
forth in Section 2.4(j) below, this Section 2.4 shall apply to any Stockholder Shares acquired by any Management Stockholder, including pursuant to Section 3.1 or the exercise, conversion or exchange of any Common
Stock Equivalents before or after the date of such Management Stockholder’s Repurchase Triggering Event. 
 (b) In the event that the
Company wishes to exercise its rights pursuant to this Section 2.4, the Company shall deliver to the Management Stockholder and the members of such Person’s Group whose Stockholder Shares are being repurchased (or the heirs or
Representatives of such Persons), a written notice (the “Call Right Notice”) within ninety (90) days of the applicable Management Stockholder’s Repurchase Triggering Event that sets forth (i) the number of Stockholder
Shares to be repurchased, (ii) the Repurchase Price and (iii) the anticipated closing date of such transaction (the date on which such Persons are so notified, the “Call Notice Date”). Any repurchase of Stockholder Shares
by the Company pursuant to this Section 2.4 shall be consummated no later than thirty (30) days following the Call Notice Date; provided, however, that such period shall be automatically extended for any period of time
in which such repurchase of Stockholder Shares would be prohibited as a result of applicable Law or any contractual obligation of the Company; provided, further, that the Company shall inform the Management Stockholder and the members
of such Person’s Group whose Stockholder Shares are being repurchased (or the heirs or Representatives of such Persons) of any such prohibitions in the Call Right Notice and shall notify such Persons once such restrictions have lapsed. 

(c) Notwithstanding anything to the contrary contained in any Existing Employment Agreement, the repurchase of Stockholder Shares by the
Company pursuant to the terms of this Section 2.4 shall be made at a per Stockholder Share price equal to the lower of the Issue Price or the Fair Market Value of such Stockholder Share as of the last day of the month preceding the date
upon which a Call Right Notice is delivered (the “Repurchase Price”). 
 (d) The Repurchase Price shall be paid to the
applicable Management Stockholder in a lump sum cash payment on the date of consummation (less any withholding tax required to be paid over to applicable Governmental Authorities). Each Management Stockholder agrees that upon such Person’s
receipt of such Repurchase Price, any outstanding Stockholder Shares then owned by such Person that are sold pursuant to this Section 2.4 shall automatically be Transferred, sold and assigned to the Company, and the Secretary of the
Company shall automatically and irrevocably be appointed to Transfer such Stockholder Shares to the Company on the books of the Company with full power of substitution. 

(e) With respect to any repurchase of Stockholder Shares pursuant to the terms of this Section 2.4, the delivery of a certificate
or certificates representing such Stockholder Shares shall 

  
 -16- 

 
be deemed a representation and warranty by such Management Stockholder that (i) such Management Stockholder has full right title and interest in and to such Stockholder Shares,
(ii) (ii) such Management Stockholder has all necessary power, authority and legal capacity and has taken all necessary action to enter into such sale transaction and to Transfer valid right, title and interest in such Stockholder Shares,
(iii) such Stockholder Shares are free and clear of any and all liens, pledges or other encumbrances, (iv) there is no adverse claim with respect to such Stockholder Shares and (v) such sale transaction does not conflict with any
Laws, contracts or organizational documents applicable to him, her or it as the result of such sale transaction. Additionally, the applicable Management Stockholder agrees to provide such other representations and warranties to the Company that the
Company reasonably determines are required by applicable Law. 
 (f) The Company shall have the right to revoke the Call Right Notice or its
decision to repurchase Stockholder Shares pursuant to the terms of this Section 2.4 at any time prior to consummation. 
 (g)
Should the applicable Management Stockholder fail to deliver at the closing of a repurchase in accordance with this Section 2.4 all of the applicable Stockholder Shares in accordance with the terms hereof, if the Repurchase Price has
been paid in accordance with Section 2.4(d), the Company shall, in addition to all other remedies it may have, cancel on its books such Stockholder Shares registered in the name of such Management Stockholder, and all of such Management
Stockholder’s right, title, and interest in and to such Stockholder Shares shall terminate in all respects concurrently with the payment of the Repurchase Price. 

(h) If a Management Stockholder holds Stockholder Shares which the Company wishes to repurchase in accordance with this
Section 2.4, such Management Stockholder shall be entitled to payment in accordance with Section 2.4(c), but shall no longer be entitled to participation in the Company or enjoy other rights as a Stockholder with respect to
such Stockholder Shares. To the maximum extent permitted by Law, such Management Stockholder’s rights following the Call Right Notice, with respect to the repurchase of the Stockholder Shares covered thereby, shall be solely the rights that he,
she or it has as a general creditor of the Company to receive the amount set forth in Section 2.4(c). 
 (i) The Company may
assign its call rights pursuant to this Section 2.4 to any Person, and such Person may exercise all rights of the Company pursuant to this Section 2.4 as if such Person were the Company; provided, that the exercise of
call rights by such Person is done in accordance with applicable Law, including, but not limited to, the Securities Act. 
 (j) The Company
will have no rights under this Section 2.4 or otherwise to repurchase any: (i) Smith RSU Shares; or (ii) any Stockholder Shares acquired by the Initial Management Stockholders pursuant to Section 3.1 or in any other
fashion after the Closing Date, other than upon the exercise, conversion or exchange of any Common Stock Equivalents. 
 (k) To the extent
that any Management Stockholder’s Existing Employment Agreement conflicts with the terms of this Section 2.4, the terms of this Section 2.4 shall govern and supersede any provisions contained in such Existing Employment
Agreement with respect to the Stockholder Shares.

the number or amount of the Offered Securities proposed to be issued, the purchase price therefor and any other terms or conditions of the proposed issuance, including any linked or grouped Securities which comprise Offered Securities) of such
issuance (the “Preemptive Offer Notice”) at least ten (10) Business Days prior to the date of the proposed issuance (the “Preemptive Offer Period”). Only a Stockholder who is an “accredited investor”
(as such term is defined in Rule 501 promulgated under the Securities Act) or who is not an “accredited investor” but who has appointed or appoints a purchaser representative (as such term is defined in Rule 501 under the Securities Act)
reasonably acceptable to the Company (each, an “Eligible Stockholder”) shall be eligible to exercise the option set forth in this Section 3.1. 

(b) Each Eligible Stockholder shall have the option, exercisable at any time during the Preemptive Offer Period by delivering written notice
to the Company (a “Preemptive Offer Acceptance Notice”), to subscribe for the number or amount of such Offered Securities up to his, her or its respective pro rata portion (calculated with respect to any Eligible Stockholder, by
taking the quotient obtained by dividing (i) the number of Stockholder Shares held by such Eligible Stockholder by (ii) the aggregate number of Stockholder Shares held by all Eligible Stockholders, including, in both the numerator and
denominator, any Common Stock Equivalents, whether vested or unvested) of the Offered Securities proposed to be issued; provided, however, that for purposes of this Section 3.1(b), each Eligible Stockholder may aggregate,
his, her or its respective pro rata portion (as calculated in accordance with the foregoing) among all Stockholders in his, her or its Group to the extent that such Stockholders in his, her or its Group do not elect to purchase their respective pro
rata portions of the Offered Securities. The Company shall notify each Eligible Stockholder within two (2) Business Days following the expiration of the Preemptive Offer Period of the number or amount of Offered Securities which such Eligible
Stockholder has subscribed to purchase. 
 (c) The Company may issue the part of such Offered Securities as to which Preemptive Offer
Acceptance Notices have not been timely given by the Eligible Stockholders (the “Refused Securities”) to any Person identified in, and in accordance with the terms and conditions set forth in, the Preemptive Offer Notice. Any
Refused Securities not purchased by such Person in accordance with this Section 3.1 within sixty (60) days after the date of the Preemptive Offer Notice may not be sold or otherwise disposed of until they are again offered to the
Eligible Stockholders under the procedures specified in this Section 3.1. 
 (d) Each Eligible Stockholder who elects not to
purchase all or any portion of the Offered Securities made available to such Eligible Stockholder pursuant to this Section 3.1 hereby waives any and all rights and claims it may have with respect to or arising out of the Offered
Securities that it elected not to purchase and the issuance thereof against the Company, any other Stockholder and each of their respective Representatives and Affiliates. 

  
 -18- 

 (e) Notwithstanding anything to the contrary contained herein, the Company may, in order to
expedite the issuance of the Offered Securities hereunder, issue all or a portion of such Offered Securities to one or more CCMP Investors and/or one or more of their Affiliates (each, an “Initial Subscribing Stockholder”), without
complying with the provisions of this Section 3.1; provided, that, prior to such issuance, either (i) each Initial Subscribing Stockholder agrees to offer to sell to each Eligible Stockholder who is not an Initial Subscribing
Stockholder (each such Stockholder, an “Other Eligible Stockholder”) up to such Other Eligible Stockholder’s respective pro rata portion (calculated with respect to any Other Eligible Stockholder, by taking the quotient
obtained by dividing (A) the number of Stockholder Shares held by such Eligible Stockholder by (B) the aggregate number of Stockholder Shares held by all Eligible Stockholders, including, in both the numerator and denominator, any Common
Stock Equivalents, whether vested or unvested) of such Offered Securities (before giving effect to such issuance of Offered Securities) on the same terms and conditions as issued to the Initial Subscribing Stockholders and in a manner which provides
such Other Eligible Stockholder with rights substantially similar to the rights outlined in Sections 3.1(a) through (c), or (ii) the Company shall offer to sell an additional amount of Offered Securities to each Other Eligible
Stockholder only in an amount and manner which provides such Other Eligible Stockholder with rights substantially similar to the rights outlined in Sections 3.1(a) through (c). The Initial Subscribing Stockholders or the Company, as
applicable, shall offer to sell such Offered Securities to each Other Eligible Stockholder within the ninety (90) day period after the closing of the purchase of the Offered Securities by the Initial Subscribing Stockholders. During such ninety
(90) day period, (x) the Initial Subscribing Stockholders shall refrain from voting or exercising any other rights as a Stockholder with respect to such Offered Securities (including the right to Transfer such Offered Securities, except as
provided in this Section 3.1(e)), and (y) the Company shall not make any distribution or dividend in respect of such Offered Securities. 

(f) Costs incurred by or on behalf of any Eligible Stockholder in connection with any transaction contemplated by this Section 3.1
shall be borne solely by such Eligible Stockholder. 
  

	3.2	Excluded Securities. 

 The rights of the Stockholders under
Section 3.1 shall not apply to the following Securities issued by the Company or any of its Subsidiaries at any time (collectively, the “Excluded Securities”):

employee benefit, incentive or other plan, arrangement or agreement, and any Securities issued upon the exercise, conversion or exchange thereof; 

(b) Securities issued to any lenders or sources of debt financing (other than the CCMP Investors or their Affiliates (other than Octagon
Credit Investors, LLC or any of its affiliated funds)) in connection with a bona fide debt financing;

dividend or upon a stock split, recapitalization or other subdivision of Securities (provided that any such dividend, stock split, recapitalization or other subdivision is effected pro rata among the applicable Stockholders); 

  
 -19- 

 (d) Securities issued in connection with (i) the acquisition (whether by stock sale, merger,
recapitalization, asset sale or similar transaction) of another Person (or portion thereof) (other than the CCMP Investors or their Affiliates) or any of the assets of another Person (other than the CCMP Investors or their Affiliates), or
(ii) a joint venture or strategic alliance with another Person (other than the CCMP Investors or their Affiliates), in each case, that is approved by the Board; and 

(e) Securities issued in a Public Offering.

telephonic meetings of the Board); it being understood that the AIMCo Observer shall be in addition to the AIMCo Board Designee. The Company shall be required to provide the Observers with any information and materials that are
delivered to members of the Board in the same form and at the same time such information and materials are delivered to the Board. Notwithstanding the foregoing, (i) the Observers shall not be entitled to vote in any meeting of the Board, and
(ii) the Company shall be entitled to excuse the Observers from any portion of a Board meeting and/or withhold any information or materials that are delivered to members of the Board (x) when the Board discusses any matter, or such
information or materials relate to any matter, that the Company reasonably believes is reasonably likely to pose a conflict of interest for the Observers or (y) if the Observers’ attendance at such meeting, or receipt of such information
or materials, is likely to waive the attorney-client privilege of matters to be discussed by the Company and its legal advisors. The Observers shall be subject to Section 4.3 hereof and, to the extent required, shall execute a reasonable
confidentiality agreement with the Company.

the AIMCo Investor of, or any proposal by the AIMCo Investor to remove, the AIMCo Board Designee or AIMCo Observer, shall, in each case, be made by delivering to the Board a notice signed by the CCMP Investors, the Initial Management Stockholders or
the AIMCo Investor, as applicable. As promptly as practicable, but in any event upon the earlier of (i) the time immediately prior to the next Board meeting or written consent of the Board and (ii) ten (10) days after delivery of such

 (g) If and for so long as a CCMP Employee is appointed as a director or
manager to any Subsidiary Board, the AIMCo Investor shall have the right to designate one (1) director or manager to serve as a member of any such Subsidiary Board, and the Company agrees to take all necessary actions to ensure the foregoing.

 (h) In addition to and not in limitation of Article VIII below, the provisions of this Section 4.1 shall terminate
automatically upon the effective date of an IPO of the Company; provided, however, that (x) the AIMCo Investor shall retain and be provided the AIMCo Director Designation Right following an IPO of the Company; if and only if and

an IPO of the Company, and Sections 4.1(c) and 4.1(d) shall continue to apply to the AIMCo Investor with respect to the CCMP Investors’ designees or nominees to the Board
following an IPO of the Company; it being understood that if the AIMCo Director Designation Right continues following an IPO of the Company as provided in the foregoing clause, such right shall be a right to nominate or
designate a director for election that shall be submitted to the stockholders of the Company for approval; and (y) in the event that the AIMCo Designation Right does not continue following an IPO of the Company as set forth in clause
(x) of this proviso, the AIMCo Board Designee serving as a director immediately prior to the effective time of an IPO of the Company, to the extent applicable, shall continue to be a director on the initial Board of the Company immediately
following the effective time of an IPO of the Company, and, if a classified board of directors is implemented and to be in effect following the effectiveness of such IPO, the Company and the CCMP Investors will in good faith consider in which class
the AIMCo Board Designee shall be placed (it being understood that the Board will ultimately determine such classification). 
  

	4.2	Information Rights. 

 (a) From the date hereof until the termination of this
Agreement pursuant to Article VIII, the Company agrees to deliver to the CCMP Investors, the AIMCo Investor and, subject to Section 4.1(b), to any Observer the Company’s: (i) audited annual financial statements and
unaudited quarterly financial statements; (ii) annual business plans showing projected financials and (iii) unaudited monthly financial statements, in each case with respect to each of the items in the foregoing clauses (i), (ii) and

supplemented or restated from time to time. 
 (b) Each CCMP Investor and the AIMCo Investor shall be permitted, during normal business
hours and upon reasonable advance notice to the Company, to (i) inspect the properties, books, records, contracts and agreements of the Company and its Subsidiaries for any proper purpose and (in the case of such books, records, contracts and
agreements) make copies thereof and (ii) obtain any information reasonably requested by such CCMP Investor or the AIMCo Investor, as applicable, relating to the Company and its Subsidiaries (including by way of telephone conferences or meetings
with officers, employees, attorneys, accountants or auditors of the Company or its Subsidiaries); provided, however, that the Company shall not be required to provide access to any (x) personnel records, (y) information which
it is legally or contractually required to maintain in confidence, or (z) information which the Board reasonably determines is highly sensitive; provided, further, that the Company may limit the information rights set forth in
this Section 4.2(b) of any of the CCMP Investors or the AIMCo Investor, as applicable, to the extent permitted by applicable Law. 
  

	4.3	Confidentiality. 

 Except as compelled by Law or administrative or judicial
process or proceeding, each Stockholder agrees not to use for its own benefit or the benefit of its Affiliates, other than the Company and its Subsidiaries (except in evaluating the Company and investment and business decisions relating thereto), or
disclose to anyone, any information furnished to it by or on behalf 

  
 -22- 

 
of the Company or its Subsidiaries (“Confidential Information”); provided, however, that any information which (a) at the time of disclosure or thereafter is
generally known by the public (other than as a result of its disclosure by such Stockholder in violation of this Section 4.3), (b) has been independently developed or derived by such Stockholder or (c) was or becomes available
to such Stockholder on a non-confidential basis from any Person who is (i) not an employee, director or Affiliate of the Company or any of its Subsidiaries, (ii) not an advisor, consultant, investment banker, commercial banker, lawyer,
accountant or other Representative (or any employee or agent of any of the foregoing) which, in each case, is or has been providing services to the Company or its Subsidiaries, or (iii) to the knowledge of such Stockholder, not otherwise bound
by a confidentiality agreement with the Company or any of its Subsidiaries, shall not be considered to be Confidential Information. If such Stockholder is compelled by Law or administrative or judicial process or proceeding to disclose any
Confidential Information, such Stockholder shall, to the extent permitted by Law, promptly inform the Company of any such required disclosure so that the Company may seek a protective order or other appropriate remedy and/or waive compliance with
the provisions of this Section 4.3. For purposes of the preceding sentence, such Stockholder may, without liability hereunder, disclose that portion of such Confidential Information that such Stockholder reasonably concludes in good
faith, after consulting with such Stockholder’s counsel, is reasonably necessary to avoid committing a violation of Law or administrative or judicial process or proceeding; provided, that, such Stockholder must exercise reasonable
efforts to preserve the confidentiality of such Confidential Information, including, by cooperating with the Company’s or its Subsidiary’s reasonable efforts to obtain an appropriate protective order or other assurance that confidential
treatment will be accorded to such Confidential Information. A Stockholder may disclose Confidential Information to its Representatives who reasonably need to know such Confidential Information to assist such Stockholder. Each Stockholder agrees to
cause its Representatives who have received Confidential Information to comply with this Section 4.3 as if such Representative was a Stockholder. Each Stockholder will be liable for a breach of this Section 4.3 by its
Representatives. Notwithstanding the foregoing, Confidential Information may be disclosed to bona-fide prospective purchasers of Stockholder Shares in connection with a Transfer thereof permitted under this Agreement (including pursuant to
Section 2.2 or Section 2.3); provided, that such Stockholder require that any Transferee of Confidential Information keep such Confidential Information confidential, consistent with this Section 4.3, and
that such Stockholder shall remain liable for a breach of this Section 4.3 by the recipient of such Confidential Information. Notwithstanding the foregoing, nothing in this Section 4.3 shall in any way limit the CCMP
Investors or any of their Affiliates from reasonably disclosing Confidential Information (i) in connection with financial or operating reports made available to the limited partners, investors, managers, members, representatives and advisors of
the CCMP Investors; (ii) in compliance with the terms of the limited partnership or other organizational documents of the CCMP Investors or any of their Affiliates; (iii) in connection with the marketing of investment funds managed or
advised, directly or indirectly, by the CCMP Investors or any of their Affiliates; or (iv) to any Governmental Authority or self-regulatory organization that has jurisdiction over the CCMP Investors or any of their Affiliates or in any filings
or applications made by the CCMP Investors or any of their Affiliates to such Governmental Authority or self-regulatory organization. In furtherance of this Section 4.3, but subject to the preceding sentence, each Other Stockholder
acknowledges that any Confidential Information furnished to such Other Stockholder or any member of his, her or its Group by or on behalf of the Company or its Subsidiaries is the sole 

  
 -23- 

 
and exclusive property of the Company and its Subsidiaries, and each Other Stockholder and each member of his, her or its Group shall hold such Confidential Information in strict confidence,
shall not disclose it to any unauthorized Person, and shall not use such Confidential Information for his, her or its own purpose. Notwithstanding the foregoing, any Stockholder (or any of such Stockholder’s Affiliates) who serves (x) the
Company in a fiduciary capacity (e.g., as a Director, officer or agent) or (y) as an advisor to the Company, may in good faith use or disclose Confidential Information to the extent consistent with such Stockholder’s (or Affiliate’s)
fiduciary duties or contractual obligations to the Company. Each Stockholder acknowledges and agrees that all proprietary interests, including intellectual property interests, resulting from the services carried out by such Stockholder, directly or
indirectly resulting from such Stockholder’s duties and obligations as an employee or consultant of the Company or any of its Subsidiaries, shall be the property of the Company or such Subsidiary, as applicable, and such Stockholder agrees to
execute such documentation as requested by the Company or such Subsidiary to confirm such ownership. 
  

	4.4	Indemnification Matters; Corporate Opportunities. 

 (a) The Company and each of
its Subsidiaries acknowledges that the Directors that are employees of the CCMP Investors, the AIMCo Investor or one of their respective Affiliates (each such Person, an “Indemnitee”) may have certain rights to indemnification,
advancement of expenses and/or insurance provided by the CCMP Investors, the AIMCo Investor and their respective Affiliates (collectively, the “Fund Indemnitors”). The Company and each of its Subsidiaries agrees that (i) the
Company and its Subsidiaries are the indemnitors of first resort (i.e., its obligations to the Indemnitees are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or
liabilities incurred by the Indemnitees are secondary), (ii) the Company and its Subsidiaries shall be required to advance the full amount of expenses incurred by the Indemnitees and shall be liable for the full amount of all expenses,
judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Section 4.4(a) and the Bylaws from time to time (or any other agreement between the Company and the
Indemnitees), without regard to any rights the Indemnitees may have against the Fund Indemnitors, and (iii) the Company and its Subsidiaries irrevocably waive, relinquish and release the Fund Indemnitors from any and all claims against the Fund
Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company and each of its Subsidiaries further agrees that no advancement or payment by the Fund Indemnitors on behalf of the Indemnitees with respect
to any claim for which the Indemnitees have sought indemnification from the Company shall affect the foregoing, and the Fund Indemnitors shall have a right of contribution and/or to be subrogated to the extent of such advancement or payment to all
of the rights of recovery of the Indemnitees against the Company. The Company and the Indemnitees agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 4.4(a). 

(b) Any amendment or repeal of any indemnification provisions of this Section 4.4, the Certificate or Bylaws or the certificate of
incorporation or bylaws of any Subsidiary shall not adversely affect any right or protection hereunder or thereunder of any Indemnitee in respect of any act or omission occurring prior to the time of such amendment or repeal (regardless of whether
the proceeding relating to such act or omission, or any proceeding relating to such Indemnitee’s rights to indemnification or to advancement of expenses, is commenced before or 

  
 -24- 

 
after the time of such amendment, repeal, modification, or adoption), and any such amendment, repeal, modification, or adoption that would adversely affect such Indemnitee’s rights to
indemnification or advancement of expenses hereunder shall be ineffective as to such Indemnitee, except with respect to any proceeding that relates to or arises from (and only to the extent such proceeding relates to or arises from) any act or
omission of such Indemnitee occurring after the effective time of such amendment, repeal, modification, or adoption. 
 (c) The Company,
each of its Subsidiaries, and each Stockholder recognizes that the CCMP Investors and the AIMCo Investor are each affiliated with private equity funds and that they, their respective members, partners or investors, invest in, serve on the board of
directors and other governing boards of, serve as officers of, provide services to and have minority and Controlling ownership interests in, existing and future operating companies. Except for the confidentiality obligations contained in
Section 4.3 of this Agreement, nothing in this Agreement or the nature of the existing or any future relationship between any CCMP Investor or the AIMCo Investor, on the one hand, and the Company, its Subsidiaries or any Stockholder, on
the other (whether such relationship is by reason of any CCMP Investor or the AIMCo Investor acting as a lender, owner of capital stock or warrants, landlord, service provider or otherwise), will prohibit any CCMP Investor or the AIMCo Investor, as
applicable, from engaging in any activity or business opportunity whatsoever for its own account or will require any CCMP Investor or the AIMCo Investor, as applicable, to make any business opportunity available to the Company or its Subsidiaries,
in each case, even if such activity or business opportunity competes with the business conducted by the Company or its Subsidiaries. 
 (d)
To the fullest extent permitted by applicable Law, the Company, for itself and each of its Subsidiaries, and the Other Stockholders, hereby renounce any interest or expectancy of the Company and each of its Subsidiaries in, or in being offered an
opportunity to participate in, any business opportunities that are presented to one or more of its officers, directors or stockholders, other than those officers, directors or stockholders who are employees of the Company or any of its Subsidiaries.
No amendment or repeal of this Section 4.1(d) shall apply to or have any effect on the liability or alleged liability of any officer, director or stockholder of the Company or any of its Subsidiaries for or with respect to any
opportunities of which such officer, director or stockholder becomes aware prior to such amendment or repeal.

REGISTRATION RIGHTS 
  

	5.1	Required Registration. 

 (a) The Company shall promptly use its best efforts to
effect the registration of Registrable Shares under the Securities Act at any time after the CCMP Investors shall request that the Company effect the registration of such Registrable Shares under the Securities Act (the CCMP Investors making such
request, the “Requesting Stockholders”), which shall be effected as a shelf registration if so requested by the Requesting Stockholders. 

  
 -25- 

 (b) Notwithstanding anything contained in this Section 5.1 to the contrary, the
Company shall not be obligated to effect any registration under the Securities Act except in accordance with the following provisions: 

(i) The Company may delay the filing or effectiveness of any registration statement for a period of up to ninety (90) days
after the date of a request for registration pursuant to Section 5.1(a) or Section 5.3 if at the time of such request: (X) the Company is engaged, or has fixed plans to engage within ninety (90) days of the time of
such request, in a firm commitment underwritten Public Offering of Primary Shares in which the holders of Registrable Shares have been or will be permitted to include all the Registrable Shares so requested to be registered pursuant to
Section 5.2 or (Y) the Board reasonably determines that such registration and offering would interfere with any Material Transaction involving the Company; or (Z) within the last forty-five (45) days the Company has
completed a firm commitment underwritten Public Offering of Primary Shares in which the holders of Registrable Shares were permitted to include all the Registrable Shares requested to be registered pursuant to Section 5.2;
provided, however, that the Company shall only be entitled to invoke its rights under this Section 5.1(b)(i) one time with respect to a request made pursuant to Section 5.1(a) during any 12-month period without
the consent of the Requesting Stockholders; 
 (ii) With respect to any registration pursuant to this Section 5.1
or Section 5.3, (a) the Company shall give prompt notice of such registration to each Stockholder that holds Registrable Shares, and shall offer to and shall include in such proposed registration any Registrable Shares requested to
be included in such proposed registration by each such Stockholder, provided that such Stockholder responds in writing to the Company’s notice within thirty (30) days after delivery by the Company of such notice (which response shall
specify the number of Registrable Shares such Stockholder is requesting to include in such registration), and (b) the Company may include in such registration any Primary Shares or Other Shares; provided, however, that if the
managing underwriter advises the Company that the inclusion of all Registrable Shares, Primary Shares and/or Other Shares proposed to be included in such registration would interfere with the successful marketing (including pricing) of the
Registrable Shares proposed to be included in such registration, then the number of Registrable Shares, Primary Shares and/or Other Shares proposed to be included in such registration shall be included in the following order: 

(A) first, the Registrable Shares owned by the Stockholders (including those requesting registration pursuant to this
Section 5.1 and Section 5.2), pro rata based upon the number of Registrable Shares owned by the Stockholders; provided, that if the managing underwriter advises the Company that the inclusion of all Registrable Shares
proposed to be included in such registration would materially adversely affect the offering and sale (including pricing) of all such Securities, then the number of Registrable Shares to be included in such registration shall be allocated among the
Stockholders on a pro rata basis in accordance with the number of Registrable Shares owned by the Stockholders who have requested inclusion; 

(B) second, the Primary Shares; and 

(C) third, the Other Shares; 

  
 -26- 

 provided, that at the election of the Company, (i) any registration pursuant to this

the Requesting Stockholders, the Primary Shares may be set at the same priority level as the Registrable Shares thereby being cutback on a pro rata basis based upon the number of Registrable Shares and Primary Shares requested to be included in such
Registration Statement by the Stockholders and the Company. 
 (c) If the holders of the Registrable Shares requesting to be included in a
registration pursuant to Section 5.1(a) or Section 5.3 so elect, the offering of such Registrable Shares pursuant to such registration shall be in the form of an underwritten Public Offering. The holders of a majority of the
Registrable Shares to be registered shall select one or more nationally recognized firms of investment bankers reasonably acceptable to the Company to act as the lead managing underwriter or underwriters in connection with such offering. 

(d) At any time before the registration statement covering such Registrable Shares becomes effective, the Requesting Stockholders may request
the Company to withdraw or not to file the registration statement. 
 (e) The Company shall not be obligated to effect any registration
under the Securities Act requested by the CCMP Investors under this Section 5.1 if the anticipated gross offering price of all Registrable Shares to be included therein would be less than $10,000,000. 

(f) The CCMP Investors shall have an unlimited number of requests under this Section 5.1. 

 

	5.2	Piggyback Registration. 

 (a) If the Company, at any time, proposes for any reason
to register any of its Securities (in any event either for its own account or for the account of other security holders) under the Securities Act (other than on Form S-4 or Form S-8 promulgated under the Securities Act (or any successor forms
thereto)), it shall give written notice to each Stockholder that holds Registrable Shares of its intention to so register such Securities at least 30 days before the initial filing of the registration statement related thereto and, upon the request,
delivered to the Company within 20 days after delivery of any such notice by the Company, of each such Stockholder to include in such registration Registrable Shares (which request shall specify the number of Registrable Shares proposed to be
included in such registration), the Company shall use its best efforts to cause all such Registrable Shares to be included in such registration on the same terms and conditions as the Securities otherwise being sold in such registration;
provided, however, that if the managing underwriter, if any, advises the Company that the inclusion of all Primary Shares and Registrable Shares requested to be included in such registration would interfere with the successful
marketing (including pricing) of the shares of Common Stock proposed to be registered by the Company, then the number of Primary Shares, Registrable Shares and Other Shares proposed to be included in such registration shall be included in the order
set forth below: 
 (i) first, the Primary Shares; 

  
 -27- 

 (ii) second, the Registrable Shares owned by Stockholders requesting that their
Registrable Shares be included in such registration pursuant to the terms of this Section 5.2, pro rata based upon the number of Registrable Shares owned by each such Stockholder at the time of such registration; and 

(iii) third, the Other Shares. 

(b) No registration effected pursuant to this Section 5.2 shall relieve the Company of its obligation to effect any registration
upon request under Section 5.1, nor shall any registration under this Section 5.2 be deemed to have been effected pursuant to Section 5.1. The Company will pay all expenses of registration in connection with each
registration pursuant to this Section 5.2. 
 (c) The number of requests permitted by the applicable Stockholders pursuant to
this Section 5.2 shall be unlimited. 
  

	5.3	Registration on Form S-3 or Form S-3ASR.

of Registrable Shares in accordance with this Section 5.3 (a “Shelf Registration”). 
 (b) If the Company shall
be requested in writing by the CCMP Investors to effect a registration under the Securities Act of Registrable Shares in accordance with this Section 5.3, then the Company shall promptly give written notice of such proposed registration
to each other Stockholder that holds Registrable Shares and shall offer to and shall include in such proposed registration any Registrable Shares requested to be included in such proposed registration by each such other Stockholder; provided,
that such other Stockholder responds in writing to the Company’s notice within thirty (30) days after delivery by the Company of such notice (which response shall specify the number of Registrable Shares such other Stockholder is
requesting to include in such registration). The Company shall promptly use its commercially reasonable efforts to effect such registration on Form S-3, providing for an offering to be made on a continuous basis pursuant to Rule 415 under the
Securities Act relating to the offer and sale, from time to time, of the Registrable Shares that the Company has been so requested to register. 

(c) The Company shall not be obligated to effect any registration under the Securities Act requested by the CCMP Investors AIMCounder this

(d) The CCMP Investors shall have an unlimited number of requests under this Section 5.3. 

(e) The AIMCo Investor shall not be entitled to sell Registrable Securities included in any Shelf Registration by utilizing such Shelf

would have to execute a lock-up or holdback agreement for the benefit of any underwriter; (iii) the Company would have to cause legal opinions to be delivered; or (iv) the Company would be obligated to cause comfort letters to be delivered
in connection with the proposed registration. Notwithstanding anything to the contrary set forth in this Section 5.3(f), to the extent the CCMP Investors propose to sell any of their Registrable Securities pursuant to and under a Shelf
Registration, the AIMCo Investor shall be entitled to participate in such sale pursuant to and in accordance with Section 5.2 up to an amount of its Registrable Shares equal to a fraction, the numerator being the number of Registrable
Shares the CCMP Investors propose to sell and the denominator being the total number of Registrable Shares owned by the CCMP Investors immediately prior to such proposed sale; the restrictions set forth in subclauses (i) – (iv) above
shall not apply to the AIMCo Investor’s participation in a sale pursuant to and under a Shelf Registration pursuant to this sentence if the event or circumstance described in such restriction would have already existed as a result of the
participation in such sale by the CCMP Investors. 
  

	5.4	Holdback Agreement. 

 (a) If the Company at any time shall register an offering
and sale of shares of Common Stock under the Securities Act in an underwritten Public Offering (i) pursuant to an IPO or (ii) pursuant to any other registration under the Securities Act (other than on Form S-4 or Form S-8), no Stockholder

the case of the IPO) without the prior written consent of such Stockholder. 
 (b) If the Company at any time pursuant to
Section 5.1 shall register under the Securities Act an offering and sale of Registrable Shares held by Stockholders for sale to the public pursuant to an underwritten Public Offering, the Company shall not, without the prior written
consent of the lead underwriters for such offering, effect any public sale or distribution of Securities similar to those being registered, or any Securities convertible into or exercisable or exchangeable for such Securities, for such period as
shall be determined by the lead underwriters and that is for the same period and on substantially similar terms as agreed to by the CCMP Investors.

pursuant to the provisions of this Agreement to use its best efforts to effect the registration of an offering and sale of any Registrable Shares, the Company shall, as expeditiously as practicable:

Stockholders for the benefit of the Management Stockholders whose Registrable Shares are to be covered by such Registration Statement (the “Management Stockholders’ Counsel”), as well as copies of all such other documents
proposed to be filed (it being understood that such five (5) Business Day period need not apply to successive drafts of the same document proposed to be filed so long as such successive drafts are supplied to such counsel in advance of the
proposed filing by a period of time that is customary and reasonable under the circumstances), and shall use its reasonable best efforts to reflect in each such document, when so filed with the Commission, such comments as the Stockholders whose
Registrable Shares are to be covered by such Registration Statement may reasonably propose;

seller, prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such Prospectus as may be necessary so that, as thereafter delivered to the offerees of such shares, such Prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; 

(i) make available for inspection by any seller of such Registrable Shares, any underwriter participating in any disposition pursuant to such
Registration Statement and any attorney, accountant or other agent retained by any such seller or underwriter (collectively, the “Inspectors”), all pertinent financial, business and other records, pertinent corporate documents and
properties of the Company (collectively, the “Records”), as shall reasonably be necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all
information (together with the Records, the “Information”) reasonably requested by any such Inspector in connection with such Registration Statement (and any of the Information that the Company determines in good faith to be

 (a) In connection with any registration of any offering and
sale of Registrable Shares under the Securities Act pursuant to this Agreement, the Company and its Subsidiaries shall indemnify and hold harmless each seller of such Registrable Shares, each underwriter, broker or any other Person acting on behalf
of such seller, each other Person, if any, who Controls any of the foregoing Persons within the meaning of the Securities Act and each Representative of any of the foregoing Persons, against any losses, claims, damages or liabilities, joint or
several, to which any of the foregoing Persons may become subject, whether commenced or threatened, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or 

  
 -33- 

 
actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement under which such Registrable
Shares were registered, any Prospectus contained therein, any offering circular, offering memorandum or Disclosure Package, or any amendment or supplement thereto, or any document incident to registration or qualification of any offering and sale of
any Registrable Shares, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or, with respect to any Prospectus,
necessary to make the statements therein in light of the circumstances under which they were made not misleading, or any violation by the Company or any of its Subsidiaries of the Securities Act or state securities or “blue sky” Laws
applicable to the Company or any of its Subsidiaries and relating to action required or inaction of the Company or its Subsidiaries in connection with such registration or qualification under such state securities or “blue sky” Laws, and
the Company and its Subsidiaries shall promptly reimburse such seller, underwriter, broker, Controlling Person or Representative for any legal or other expenses incurred by any of them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that neither the Company nor its Subsidiaries shall be liable to any such Person to the extent that any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission made in said Registration Statement, preliminary Prospectus, amendment thereto, or any document incident to registration or qualification of any Registrable Shares in
reliance upon and in conformity with written information furnished to the Company or its Subsidiaries through an instrument duly executed by such Person, or a Person duly acting on their behalf, specifically for use in the preparation thereof. 

(b) In connection with any registration of an offering and sale of Registrable Shares under the Securities Act pursuant to this Agreement,
each seller of Registrable Shares severally, and not jointly, shall indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 5.7(a)) the Company, its Subsidiaries, each underwriter or broker involved
in such offering, each other seller of Registrable Shares under such Registration Statement, each Person who Controls any of the foregoing Persons within the meaning of the Securities Act and any Representative of the foregoing Persons with respect
to any untrue statement or allegedly untrue statement or omission or alleged omission contained in the Registration Statement under which such Registrable Shares were registered, any Prospectus contained therein, any offering circular, offering
memorandum or Disclosure Package, or any amendment or supplement thereto, or any document incident to registration or qualification of any offering and sale of any Registrable Shares, if such statement or omission was made in reliance upon and in
conformity with written information furnished to the Company, its Subsidiaries, or such underwriter through an instrument duly executed by such seller or a Person duly acting on such seller’s behalf specifically for use in connection with the
preparation of such Registration Statement, preliminary Prospectus, final Prospectus, Free Writing Prospectus, amendment or supplement; provided, however, that the maximum amount of liability in respect of such indemnification shall be
limited, in the case of each seller of Registrable Shares, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Shares effected pursuant to such registration. 

(c) Promptly after receipt by an indemnified party of notice of the commencement of any action involving a claim referred to in the preceding
paragraphs of this Section 5.7, such 

  
 -34- 

 
indemnified party will, if a claim in respect thereof is not made against an indemnifying party, give written notice to the latter of the commencement of such action (provided,
however, that an indemnified party’s failure to give such notice in a timely manner shall only relieve the indemnification obligations of an indemnifying party to the extent such indemnifying party is materially prejudiced by such
failure). In case any such action is brought against an indemnified party, the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that
it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election to assume the defense thereof, the indemnifying party shall not be responsible for
any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof; provided, however, that if any indemnified party shall have reasonably concluded (based upon the written advice of
counsel) that there may be one or more legal or equitable defenses available to such indemnified party which are in addition to or in conflict with those available to the indemnifying party, or that such claim or litigation involves or could have an
effect upon matters beyond the scope of the indemnity agreement provided in this Section 5.7, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party and such indemnifying
party shall reimburse such indemnified party and any Person Controlling such indemnified party for that portion of the fees and expenses of any one lead counsel (plus appropriate special and local counsel) retained by the indemnified party that are
reasonably related to the matters covered by the indemnity agreement provided in this Section 5.7; provided, further, that, if there is more than one indemnified party, then the indemnifying party shall only be required to
reimburse the expenses for the lead counsel (plus appropriate special and local counsel) approved in writing by the indemnified party or parties (as applicable) holding a majority of the Registrable Shares held by all indemnified parties. 

(d) If the indemnification provided for in this Section 5.7 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, claim, damage or liability referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amounts paid or payable by such indemnified
party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other hand in connection with the statements
or omissions that resulted in such loss, claim, damage or liability as well as any other relevant equitable considerations; provided, however, that the maximum amount of liability in respect of such contribution shall be limited, in
the case of each seller of Registrable Shares, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Shares effected pursuant to such registration. The relative fault of the indemnifying party and of
the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by
the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. No Person guilty of fraud shall be entitled to indemnification or contribution hereunder.

 (e) The indemnification and contribution provided for under this Agreement will remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party and will survive the Transfer of Registrable Shares. 

  
 -35- 

	5.8	Underwriting Agreement. 

 (a) Notwithstanding the provisions of Sections
5.4, 5.5 and 5.7, to the extent that the Stockholders selling Registrable Shares in a proposed registration shall enter into an underwriting or similar agreement that contains provisions covering one or more issues addressed in
such Sections of this Agreement, the provisions contained in such Sections of this Agreement addressing such issue or issues shall be of no force or effect with respect to such registration, but this provision shall not apply to the Company if the
Company is not a party to the underwriting or similar agreement. 
 (b) If any registration pursuant to Sections 5.1 or 5.3 is
requested to be an underwritten Public Offering, the Company shall negotiate in good faith to enter into a reasonable and customary underwriting agreement with the underwriters thereof. The Company shall make such representations and warranties to
the holders of Registrable Securities being registered, and the underwriters or agents, if any, in form, substance and scope as are customarily made by issuers in secondary underwritten public offerings and take any other actions as such holders, or
the underwriter or underwriters, if any, reasonably request in order to expedite or facilitate the registration and disposition of such Registrable Securities. The Company and its Subsidiaries shall be entitled to receive indemnities from lead
institutions, underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the distribution, to the same extent as provided above with respect to information so furnished in writing by such Persons
specifically for inclusion in any Prospectus or Registration Statement and to the extent customarily given their role in such distribution. 

(c) No Stockholder may participate in any registration hereunder that is underwritten unless such Stockholder agrees to sell such
Stockholder’s Registrable Shares proposed to be included therein on the basis provided in any underwriting arrangements reasonably acceptable to the Company in the case of an offering of Primary Shares, or, in the case of an offering pursuant
to Section 5.1 hereof, reasonably acceptable to the Company and the Requesting Stockholders. 
  

	5.9	Information by Holder. 

 Each holder of Registrable Shares to be included in any
registration shall furnish to the Company and the managing underwriter such written information regarding such holder and the distribution proposed by such holder as the Company or the managing underwriter may reasonably request in writing and as
shall be reasonably required in connection with any registration, qualification or compliance referred to in this Agreement. Each Stockholder shall as expeditiously as possible, notify the Company of the occurrence of any event concerning such
Stockholder as a result of which the Prospectus relating to such registration contains an untrue statement of material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. 

  
 -36- 

	5.10	Exchange Act Compliance. 

 From and after the date a registration statement is
filed by the Company pursuant to the Exchange Act relating to the Company’s Securities and shall have become effective, the Company shall comply with all of the reporting requirements of the Exchange Act (whether or not it shall be required to
do so) and shall comply with all other public information reporting requirements of the Commission that are conditions to the availability of Rule 144 for the sale of the Common Stock. The Company shall cooperate with each Stockholder in supplying
such information as may be necessary for such Stockholder to complete and file any information reporting forms presently or hereafter required by the Commission as a condition to the availability of Rule 144. 

 

	5.11	Suspension. 

 Anything contained in this Agreement to the contrary
notwithstanding, the Company may (not more than once with respect to any registration) with the written consent of the CCMP Investors, by notice in writing to each holder of Registrable Shares to which a Prospectus relates, require such holder to
suspend, for up to sixty (60) days (the “Suspension Period”), the use of any Prospectus included in a registration statement filed under this Article V if a Material Transaction exists that would require an amendment to
such registration statement or supplement to such Prospectus (including any such amendment or supplement made through incorporation by reference to a report filed under Section 13 of the Exchange Act). The period during which such Prospectus
must remain effective shall be extended by a period equal to the Suspension Period. The Company may (but shall not be obligated to) withdraw the effectiveness of any registration statement subject to this provision. 

ARTICLE VI 
 SECURITIES
LAW COMPLIANCE; LEGENDS 
  

	6.1	Restriction on Transfer. 

 (a) In addition to any other restrictions on the
Transfer of Stockholder Shares contained in this Agreement, the Stockholders shall not Transfer any Stockholder Shares except in compliance with the conditions specified in this Article VI. Any Transfer of Stockholder Shares by any
Stockholder that is not in compliance with this Article VI and the other terms and conditions set forth in this Agreement shall render such Transfer null and void. 

(b) No Stockholder shall Transfer any Stockholder Shares held thereby without the prior written consent of the Board (which may be granted or
withheld in its reasonable discretion), other than (i) with respect to an Other Stockholder who is a natural person, any Transfer of Stockholder Shares by such Other Stockholder to (x) any member of such Other Stockholder’s Group
consummated solely for estate planning purposes or (y) the estate of such Other Stockholder upon his or her death, (ii) with respect to an Other Stockholder that is a trust Controlled solely by such Other Stockholder, any Transfer of
Stockholder Shares by such Other Stockholder to the beneficiaries of such trust, or (iii) Transfers of Stockholder Shares (A) pursuant to Section 2.2, Section 2.3 or Section 2.4, (B) pursuant to
Rule 144 following an IPO or (C) pursuant to an effective Registration Statement; provided, however, that, in the case of 

  
 -37- 

 
clauses (i) and (ii), any such Transfer must be made in accordance with the other terms and conditions of Article II and this Article VI and no Permitted Transferee may make a
subsequent Transfer without the prior written consent of the Board. 
 (c) Notwithstanding anything to the contrary set forth herein, the
Company shall consent to any Transfer of any Stockholder Shares held by the AIMCo Investor to an AIMCo Client; provided that (i) the AIMCo Investor will remain liable for all liabilities and obligations relating to the Transfer unless
and until the AIMCo Client is substituted as a Stockholder of the Company pursuant to Section 6.6 hereof, (ii) such Transfer is not to a Person that directly, or indirectly, carries on, or engages in, or is concerned with, or is
interested in any business that manufactures, sells or distributes the products of the Business manufactured by the Company, (iii) such Transfer would not violate the registration or qualification provisions of the Securities Act, any state or
securities “blue sky” or non-U.S. Securities laws applicable to the Company or the Stockholder Shares to be Transferred, (iv) such Transfer would not cause the Company to become subject to the registration requirements of the
Securities Exchange Act of 1934, as amended, (v) such Transfer would not violate the laws, rules or regulations of any state or any governmental authority applicable to such Transfer, and (vi) such Transfer would not otherwise subject the
Company or any of its Subsidiaries to any new material compliance obligations or reporting obligations beyond what is required in this Agreement. In any circumstance where the Company is required to consent to a Transfer in accordance with the
immediately preceding sentence, the Company will not unreasonably withhold its consent to the substitution of such Permitted Transferee as a Stockholder. 

(d) Following an IPO of the Company, until such time as the CCMP Investors have consummated a secondary sale after such IPO of any of the
Stockholder Shares owned by the CCMP Investors immediately prior to an IPO of the Company (any such sale by the CCMP Investors following an IPO of the Company, the “CCMP First Post-IPO Sale”), the AIMCo Investor shall not Transfer
any Stockholder Shares (other than to Permitted Transferees pursuant to Section 6.1(b)), including any Transfers pursuant to a registration under Sections 5.1, 5.2 and 5.3, to the extent that such Transfer would
result in the Relative Ownership Percentage (as defined below) of the AIMCo Investor immediately following the effective time of such Transfer (the “Determination Time”) being less than the Relative Ownership Percentage of the CCMP
Investors immediately following the Determination Time. For purposes of this Section 6.1(d)), “Relative Ownership Percentage” means a fraction (expressed as a percentage), (A) the numerator of which is the aggregate
number of Stockholder Shares owned by either the CCMP Investors or the AIMCo Investor, as applicable, immediately following the Determination Time and (B) the denominator of which is the aggregate number of Stockholder Shares owned by the CCMP
Investors or the AIMCo Investor, as applicable, immediately following the IPO. From and after the CCMP First-IPO Sale and the expiration of any underwriter’s lock-up or holdback agreement pursuant to Section 5.4 above, the
provisions of this Section 6.1(d) and Sections 6.1(a) and 6.1(b) above shall no longer be applicable to the AIMCo Investor. 
  

	6.2	Restrictive Legends. 

 Each certificate for Stockholder Shares shall (unless
otherwise provided by the provisions of Section 6.4) be stamped or otherwise imprinted with a legend in substantially the following terms: 

“THE SHARES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
AS AMENDED, OR ANY STATE SECURITIES OR BLUE SKY LAWS, AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS SUBSEQUENTLY REGISTERED THEREUNDER OR AN EXEMPTION FROM REGISTRATION THEREUNDER IS AVAILABLE.” 

  
 -38- 

	6.3	Notice of Transfer. 

 The holder of any Stockholder Shares, by his, her or its
acceptance or purchase thereof, agrees, prior to any Transfer of any such Stockholder Shares (except pursuant to an effective Registration Statement), to give written notice to the Company of such holder’s intention to effect such Transfer and
agrees to comply in all other respects with the provisions of this Article VI. Each such notice shall describe the manner and circumstances of the proposed Transfer and, unless waived by the Company, shall be accompanied by the written
opinion, addressed to the Company, of counsel for the Company or for the holder of such Stockholder Shares (which counsel shall be reasonably satisfactory to the Company; provided, that if such holder is a CCMP Investor, the opinion of its
in-house counsel shall be deemed acceptable to the Company), stating that in the opinion of such counsel (which opinion shall be reasonably satisfactory to the Company) such proposed Transfer does not involve a transaction requiring registration of
such Stockholder Shares under the Securities Act. Each certificate or other instrument evidencing the Stockholder Shares issued upon the Transfer of any Stockholder Shares (and each certificate or other instrument evidencing any untransferred
balance of such Stockholder Shares) shall bear the legend set forth in Section 6.2) unless (i) in such opinion of such counsel registration of future Transfer is not required by the applicable provisions of the Securities Act or
(ii) the Company shall have waived the requirement of such legend. 
  

	6.4	Removal of Legends, Etc. 

 Notwithstanding the foregoing provisions of this
Article VI, the restrictions imposed by Sections 6.1, 6.2 and 6.3 upon the transferability of any Stockholder Shares shall cease and terminate when (a) such Stockholder Shares are sold or otherwise disposed of in
accordance with the intended method of disposition by the seller or sellers thereof set forth in a Registration Statement or are sold or otherwise disposed of in a transaction contemplated by Section 6.3 which does not require that the
Stockholder Shares Transferred bear the legend set forth in Section 6.2, or (b) the holder of such Stockholder Shares has met the requirement of Transfer of such Stockholder Shares pursuant to Rule 144(b)(1). Whenever the
restrictions imposed by Sections 6.1, 6.2 and 6.3 shall terminate, as herein provided, the holder of any Stockholder Shares shall be entitled to receive from the Company, without expense, a new certificate not bearing the
restrictive legend set forth in Section 6.2 and not containing any other reference to the restrictions imposed by Sections 6.1, 6.2 and 6.3. 

  
 -39- 

	6.5	Additional Legend. 

 (a) Each certificate evidencing Stockholder Shares and each
certificate issued in exchange for or upon the Transfer of any Stockholder Shares (if such shares remain Stockholder Shares as defined herein after such Transfer) shall be stamped or otherwise imprinted with a legend in substantially the following
form: 
 “THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A STOCKHOLDERS’ AGREEMENT DATED AS OF APRIL 30, 2012 (AS
AMENDED, MODIFIED, SUPPLEMENTED OR RESTATED FROM TIME TO TIME, THE “AGREEMENT”), AMONG THE ISSUER OF SUCH SECURITIES (THE “COMPANY”) AND CERTAIN OF THE COMPANY’S STOCKHOLDERS. THE TERMS OF THE AGREEMENT
INCLUDE, AMONG OTHER THINGS, RESTRICTIONS ON TRANSFERS. A COPY OF THE AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST.” 

(b) The legend set forth above shall be removed from the certificates evidencing any shares which cease to be Stockholder Shares in accordance
with the terms of this Agreement. 
  

	6.6	Future Stockholders. 

 Any Permitted Transferee or member of any Stockholder Group
to which any Stockholder Shares are Transferred (who is not already a party to this Agreement) shall, as a condition to the effectiveness of such Transfer, execute a Joinder Agreement; provided, that the foregoing requirement shall not apply
to Stockholder Shares sold in a registered offering or Transferred following an IPO in accordance with Rule 144. Unless the CCMP Investors agree otherwise, whenever the Company issues or otherwise sells Securities issued by the Company to any Person
who is not a Stockholder, as a condition to the effectiveness of such issuance or sale, the Company will obtain a Joinder Agreement from such Person. Such Person shall become an Other Stockholder, unless such Person is (i) an Affiliate of a
CCMP Investor, in which case such Person shall become a CCMP Investor or (ii) an employee of the Company or its Subsidiaries or an Affiliate of such employee, in which case such Person shall become both a Management Stockholder and an Other
Stockholder (it being understood that clause (ii) supersedes clause (i) above). Any failure by any Person to obtain a Joinder Agreement from a Transferee in connection with any Permitted Transfer to the extent required under this Agreement
shall render such Transfer null and void. 
 ARTICLE VII 

AMENDMENT AND WAIVER 
  

	7.1	Amendment. 

 Except as expressly set forth herein, the provisions of this
Agreement may only be amended or waived with the prior written consent of (a) the Company and (b) the CCMP Investors; provided, however, that any amendment or waiver that would adversely affect the rights, privileges or
obligations of (i) the Management Stockholders in a manner disproportionate from the effect on the rights, privileges or obligations hereunder of the CCMP Investors shall not be effective as to the Management Stockholders without the prior
written consent of the holders of a majority of the Stockholder Shares then held by the Management Stockholders; and (ii) the AIMCo Investor in a manner disproportionate from the effect on the rights, privileges or

  
 -40- 

 
obligations hereunder of the CCMP Investors, or that would reduce or waive any of the rights of the AIMCo Investor hereunder or impose new obligations on the AIMCo Investor, shall not be
effective as to the AIMCo Investor without the prior written consent of the AIMCo Investor. Notwithstanding the foregoing, the parties hereto hereby acknowledge and agree that, without any further actions or consents of the parties hereto,
Schedule I shall be updated by the Company at the Closing, and may be amended by the Company thereafter from time to time, to reflect (i) the addition of any Stockholders as parties hereto and (ii) the number of Stockholder Shares
issued to each Stockholder. 
  

	7.2	Waiver. 

 No course of dealing between the Company and the Stockholders (or any of
them) or any delay in exercising any rights hereunder will operate as a waiver of any rights of any party to this Agreement. The failure of any party hereto to enforce any of the provisions of this Agreement will in no way be construed as a waiver
of such provisions and will not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms. 

ARTICLE VIII 

TERMINATION 
 The
provisions of this Agreement will terminate automatically upon the earlier to occur of (i) the date that no Stockholder Shares are outstanding, (ii) the effective date of an IPO by the Company and (iii) the consummation of a Liquidity
Event; provided, that Article I (Definitions; Rules of Construction), Section 4.3 (Confidentiality) (with respect to any disclosure made prior to the termination of this Agreement), Section 4.4 (Indemnification
Matters; Corporate Opportunities), Section 5.7 (Indemnification), Article VII (Amendment and Waiver), this Article VIII (Termination) and Article IX (Miscellaneous) will survive any termination of this Agreement; and
provided, further, that Section 4.1(h), Article V (Registration Rights) and Article VI (Securities Law Compliance; Legends) will also survive after an IPO. Notwithstanding the foregoing, upon the termination
of the Stock Purchase Agreement in accordance with its terms, the parties hereto agree that this Agreement will terminate and be of no further force and effect. 

ARTICLE IX 

MISCELLANEOUS 
  

	9.1	Severability. 

 It is the desire and intent of the parties hereto that the
provisions of this Agreement be enforced to the fullest extent permissible under the Laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement shall be
adjudicated by a court of competent jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting
the validity or enforceability of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid,
prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other
jurisdiction.

	9.2	Entire Agreement. 

 This Agreement, the CCMP Stock Subscription Agreements, the
Management Stock Subscription Agreements, the Boots Trust Stock Subscription Agreement, AIMCo Investor Stock Transfer Agreement and the 2012 Equity Incentive Plan (as it may be amended, supplemented or modified from time to time) embody the entire
agreement and understanding among the parties hereto with respect to the subject matter hereof and thereof and supersede and preempt any and all prior and contemporaneous understandings, agreements, arrangements or representations by or among such
parties, written or oral, which may relate to the subject matter hereof or thereof in any way. The parties hereto acknowledge and agree that (i) this Agreement, the CCMP Stock Subscription Agreements, the Management Stock Subscription
Agreements, the Boots Trust Stock Subscription Agreement, the AIMCo Investor Stock Transfer Agreement and the 2012 Equity Incentive Plan (as it may be amended, supplemented or modified from time to time) include provisions related to the same or
similar rights and obligations of the parties hereto and thereto, as applicable, including with respect to non-competition, non-solicitation and confidentiality restrictions, among others, and (ii) all such provisions, whether contained in this
Agreement, the Stock Purchase Agreement, the CCMP Stock Subscription Agreements, the Management Stock Subscription Agreements, the Boots Trust Stock Subscription Agreement, the AIMCo Investor Stock Transfer Agreement or the 2012 Equity Incentive
Plan (as it may be amended, supplemented or modified from time to time) are intended by the parties hereto and thereto, as applicable, to co-exist with and apply in addition to, and not in lieu or modification of, any provisions contained in any
other agreement. 
  

	9.3	Independence of Agreements and Covenants. 

 All agreements and covenants hereunder
shall be given independent effect so that if a certain action or condition constitutes a default under a certain agreement or covenant, the fact that such action or condition is permitted by another agreement or covenant shall not affect the
occurrence of such default, unless expressly permitted under an exception to such initial agreement or covenant. 
  

	9.4	Successors and Assigns. 

 Except as otherwise provided herein, this Agreement will
bind and inure to the benefit of and be enforceable by the Company and its successors and permitted assigns and the Stockholders and any subsequent holders of Stockholder Shares and the respective successors and permitted assigns of each of them, so
long as they hold Stockholder Shares. Except as specifically set forth herein, the Company may not assign its rights or obligations hereunder without the prior written consent of the CCMP Investors; provided, that notwithstanding any such
assignment by the Company, the Company shall remain liable for its obligations hereunder. Notwithstanding anything to the contrary herein, (x) prior to an IPO of the Company, in the event of any Transfer by the AIMCo Investor that is approved
and permitted pursuant to Section 6.1(b) of at least a majority of the Stockholder Shares held by the AIMCo Investor as of the date of this Agreement, all (but not less than all) of the rights of the AIMCo Investor under this

  
 -42- 

 
Agreement may be assigned to the transferee in such Transfer and such transferee shall be subject to all of the obligations and limitations (including limitations relating to any such assigned
rights) of the AIMCo Investor under this Agreement; provided, however, that both the AIMCo Investor (if it is not transferring all of its shares) and the transferee must agree in writing to be subject to all the obligations and duties
of the AIMCo Investor under this Agreement; and (y) for the avoidance of doubt, in the event of any Transfer by the CCMP Investors that is permitted hereunder, the rights of the CCMP Investors under this Agreement may be assigned to the
transferee in such Transfer and such transferee shall be subject to all of the obligations and limitations (including limitations relating to any such assigned rights) of the CCMP Investors under this Agreement; provided, however, that
both the CCMP Investors (if they are not transferring all of their respective shares) and the transferee shall agree in writing to be subject to all the obligations and duties of the CCMP Investors under this Agreement. 

 

	9.5	Counterparts; Facsimile Signatures; Validity. 

 This Agreement may be executed in
two or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties hereto and delivered (by facsimile or otherwise) to the other
parties hereto, it being understood that all parties hereto need not sign the same counterpart. Any counterpart or other signature hereupon delivered by facsimile shall be deemed for all purposes as constituting good and valid execution and delivery
of this Agreement by such party. 
  

	9.6	Remedies. 

 (a) Each Stockholder shall have all rights and remedies reserved for
such Stockholder pursuant to this Agreement and all rights and remedies which such holder has been granted at any time under any other agreement or contract and all of the rights which such holder has under any Law or equity. Any Person having any
rights under any provision of this Agreement will be entitled to enforce such rights specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by Law or equity. 

(b) The parties hereto agree that if any parties hereto seek to resolve any dispute arising under this Agreement pursuant to a legal
proceeding, the prevailing parties to such proceeding shall be entitled to receive reasonable fees and expenses (including reasonable attorneys’ fees and expenses) incurred in connection with such proceedings. 

(c) It is acknowledged that it will be impossible to measure in money the damages that would be suffered by any party hereto if any other
Person party hereto fails to comply with any of the obligations imposed on it upon them in this Agreement and that in the event of any such failure, the aggrieved party will be irreparably damaged and will not have an adequate remedy at Law. Any
such aggrieved party shall, therefore, be entitled to equitable relief, including specific performance, to enforce such obligations, and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the
parties hereto shall raise the defense that there is an adequate remedy at Law.

or restated from time to time, shall in no event trigger an adjustment pursuant to this Section 9.14. 
  

	9.15	Non-Recourse. 

 Notwithstanding anything that may be expressed or implied in this
Agreement, the Company and each Stockholder covenant, agree and acknowledge that no recourse under this Agreement shall be had against any current or future director, officer, employee, general or limited partner or member or equity holder of any
Stockholder or of any Affiliate or assignee thereof, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable Law, it being expressly agreed and acknowledged that no personal liability
whatsoever shall attach to, be imposed on or otherwise be incurred by any current or future officer, agent or employee of any Stockholder or any current or future member or equity holder of any Stockholder or any current or future director, officer,
employee, partner or member or equity holder of any Stockholder or of any Affiliate or assignee thereof, as such for any obligation of any Stockholder under this Agreement for any claim based on, in respect of or by reason of such obligations or
their creation.
