 - 9 - 













 
(i) the quotient determined by dividing (A) the total number of Company Securities that are proposed to be sold directly or indirectly by the Sponsor Group to the Third Party purchaser in
the contemplated sale by (B) the total number of Company Securities directly or indirectly owned by the Sponsor Group as of the close of business on the day immediately prior to the Drag-Along Notice Date, and (ii) the total number of
Shares owned, or issuable upon exercise of any vested Stock Equivalents that are exercisable (or would become vested and exercisable as a result of the underlying transaction), by such member as of the close of business on the day immediately prior
to the Drag-Along Notice Date, at the same price per share of Stock; provided, that (I) the Drag-Along Sale is a bona fide arm’s length transaction; (II) subject to Section 3(b), if any direct or indirect holder of Company
Securities is given an option as to the form of consideration to be received, all members of a Management Stockholder Group who are holders of Shares participating in the Drag-Along Sale will be given the same option; (III) the only
representations, warranties or covenants that any member of a Management Stockholder Group would be required to make are with respect to his, her or its own ownership of the Shares to be sold by him, her or it (including his, her or its ability to
convey title free and clear of liens, encumbrances or adverse claims and reasonable covenants regarding confidentiality, publicity and similar matters); (IV) if the Drag-Along Sale involves any non-cash
consideration, any rights or restrictions with respect to the non-cash consideration payable to each member of the Management Stockholder Group may be proportionate to the relative size of ownership of such non-cash consideration, such as entitlements to board seats or demand registration rights; (V) the liability of any member of a Management Stockholder Group would be several and not joint with respect to any
representation and warranty or covenant made by the Company or its subsidiaries, and liability would be limited to the lesser of such member of a Management Stockholder Group’s pro rata share and the aggregate proceeds received by such member;
provided, that any such liability of such member shall be satisfied first by the return of any cash proceeds received by such member (including the cash proceeds from the sale of any securities or other
non-cash consideration received by such member) and second by the return of any non-cash consideration (including securities) received by such member; and (VI) any
Management Stockholder shall not be required to agree to any covenant not to compete or covenant not to solicit customers, employees or suppliers of any party to a Drag-Along Sale. Upon the Sponsor Group providing the Drag-Along Sale Notice, in the
event that a member of a Management Stockholder Group does not hold a sufficient number of Shares to meet its obligations under this Section 3(a), then a sufficient number of Stock Equivalents (that are vested and
exercisable at any time up to and including the date immediately prior to the underlying transaction or that become exercisable as a result of a Change in Control that is the subject of the Drag-Along Sale Notice) shall be exercised by such member
(which may be performed by using a net exercise method if approved by the Board or a committee thereof) to cover any such shortfall and the Shares issued upon such exercise shall be subject to the drag-along rights set forth in this
Section 3(a). Any such Stock Equivalents that are required to be exercised to cover such shortfall but are not so exercised pursuant to this Section 3(a) shall automatically be cancelled without
any consideration paid therefor. In the event that a member of a Management Stockholder Group does not have a sufficient number of such vested Stock Equivalents to cover such shortfall, such member shall exercise all such vested Stock Equivalents
then held by such member in full satisfaction of its obligations with respect to the underlying transaction. 

  
 - 10 - 













 (b) The provisions of this Section 3 shall apply regardless of the
form of consideration received in the Drag-Along Sale; provided, that, in the event the consideration to be paid in exchange for shares of Stock in a proposed Drag-Along Sale includes any securities, and the receipt thereof by a member of a
Management Stockholder Group required to sell Shares pursuant to Section 3(a) hereof would require (as determined by the Sponsor Group in good faith, upon the advice of its counsel) under applicable law (x) the
registration or qualification of such securities or of any Person as a broker or dealer or agent with respect to such securities where such registration or qualification is not otherwise required by the receipt of such securities by the Sponsor
Group, or (y) the provision to any such member of any specified information regarding such securities or the issuer thereof that is not otherwise required to be provided for in connection with the Drag-Along Sale, then, in either case of
(x) or (y), in lieu of receiving such securities (as may be required by the Sponsor Group, in its sole discretion), such member may, at the Sponsor Group’s direction, receive cash consideration equal to the fair market value of such
securities. 
 (c) The members of each Management Stockholder Group shall cooperate in good faith with the Sponsor Group in connection with
the consummation of the transactions contemplated by Section 3(a) hereof and, in the event that the Drag-Along Sale is (i) a merger or other business combination of Parent or the Company with a Third Party (or an
Affiliate thereof) or (ii) a purchase of all or substantially all of the assets of Parent, the Company (and/or its subsidiaries), then, upon the demand of the Sponsor Group, such members shall be required to vote all Shares they hold (or
execute one or more written consents) in favor of (and not otherwise oppose) the merger or business combination or sale of all or substantially all of the assets of Parent, the Company (and/or its subsidiaries), and otherwise to take all actions
reasonably necessary or appropriate to facilitate the consummation of the proposed transaction, including entering into agreements containing terms and conditions consistent with the provisions of this Section 3 as may be
reasonably necessary to consummate the merger or business combination or sale of all or substantially all of the assets of Parent, the Company (and/or its subsidiaries) and waiving any and all dissenters or appraisal rights with respect thereto.
Each member of each Management Stockholder Group hereby grants to each member of the Sponsor Group an irrevocable proxy, coupled with an interest, only if such member fails to comply promptly with the provisions of
Section 3, to vote such member’s Shares (or execute one or more written consents) in accordance with this Section 3(c), which proxy shall be valid and remain in effect until the provisions of
this Section 3 expire pursuant to Section 3(g). 
 (d) Any expenses incurred for the
benefit of Parent, the Company or all selling equityholders of Parent and/or the Company, and any indemnities, holdbacks, escrows and similar items relating to the Drag-Along Sale, that are not paid or established by Parent or the Company (other
than those that relate to representations or indemnities concerning a member of a Management Stockholder Group’s valid ownership of its Stock free and clear of all liens, claims and encumbrances or a member of a Management Stockholder
Group’s authority, power and legal right to enter into and consummate a purchase or merger agreement or ancillary documentation) shall be paid or established by all selling stockholders pro rata based on the Stock being sold (directly or
indirectly) by each of them in the Drag-Along Sale (or, if Stock is not being sold in such Drag-Along Sale, pro rata based on the net transaction proceeds to be received by each of them in the transaction).

consummate, postpone or abandon any Drag-Along Sale and the terms and conditions thereof. 
 (f) Prior to an Initial Public Offering, the
Sponsor Group shall be entitled to require all members of each Management Stockholder Group to participate in any recapitalization or restructuring transaction in connection with which Stock is converted or exchanged, pro rata, for new equity
securities (the terms and conditions of which shall not be materially and disproportionately adverse to any such member relative to any other holder of Stock), whether in preparation for an Initial Public Offering or otherwise. The other provisions
of this Section 3 shall apply to any such transaction, mutatis mutandis. Without limiting the foregoing, in connection with any such recapitalization or restructuring transaction, each member of the Management
Stockholder Group will be entitled to receive a number of shares of one or more classes containing substantially the same economic and other terms and rights relative to the Shares held by such member prior to such of recapitalization or
restructuring transaction. 
 (g) By execution of this Agreement, each member of the Management Stockholder Group hereby irrevocably appoints
KKR Clover Aggregator L.P. as his, her or its true and lawful representative and attorney-in-fact, to make, execute, sign and file on behalf of such member of such
Management Stockholder Group all instruments, documents and certificates which, from time to time, may be required with respect to the matters set forth in this Section 3 and Section 4. Such power of attorney is coupled with an interest
and shall survive and continue in full force and effect notwithstanding the disability or incapacity of such member. Furthermore, upon written request by the Sponsor Group, each member of the Management Stockholder Group agrees to execute any
additional custody agreements or powers of attorney as may be reasonably requested by the Sponsor Group to effect the matters set forth in this Section 3 and Section 4 including, among other things, that such member will deliver to and
deposit in custody with the custodian and attorney-in-fact named therein a certificate or certificates (if such shares are certificated) representing such Shares (with
undated stock powers duly endorsed in blank for Transfer by the registered owner or owners thereof) and irrevocably appointing such custodian and attorney-in-fact as
such member’s agent and attorney-in-fact with full power and authority to act on such member’s behalf with respect to the matters specified therein. 

(h) The rights set forth in this Section 3 shall terminate immediately prior to the consummation of the Initial
Public Offering. 
 4. Tag-Along Rights.  

(a) If at any time the Sponsor Group proposes to enter into an agreement to sell or otherwise dispose of (directly or indirectly) for value any
Company Securities, other than (i) a sale or disposition that would trigger piggy-back registration rights under Section 7 hereof, (ii) any direct or indirect Transfer of Stock to another member of the Sponsor
Group or an Affiliate thereof, (iii) any Repurchase effected in compliance with Section 8 below or (iv) any customary syndications of up to 25% of the Company Securities directly or indirectly owned by the Sponsor
Group (such sale or other disposition for value being referred to as a “Tag-Along Sale”), then, except as provided in Section 4(g), the Sponsor Group shall afford each member of each
Management Stockholder Group whose Management Stockholder Group holds, in the 

  
 - 12 - 













 
aggregate, more than 100 Shares and/or vested Stock Equivalents that are exercisable (or would become vested and exercisable as a result of the Tag-Along
Sale) (each, individually, a “Tag-Along Stockholder” and, collectively, the “Tag-Along Stockholders”) the opportunity to participate
proportionately in such Tag-Along Sale in accordance with this Section 4. The maximum number of Shares that each Tag-Along Stockholder will be
entitled to include in such Tag-Along Sale (such Tag-Along Stockholder’s “Tag-Along Allotment”) shall be
equal to the product (rounded up to the nearest whole number) of (x) the number of Shares owned, or issuable upon exercise of any vested Stock Equivalents that are exercisable (or would become vested and exercisable as a result of the Tag-Along Sale), by such Tag-Along Stockholder as of the close of business on the day immediately prior to the Tag-Along Notice Date
(as defined in Section 4(b) hereof) and (y) a fraction, the numerator of which is the number of Company Securities proposed by the Sponsor Group to be Transferred directly or indirectly pursuant to the Tag-Along Sale and the denominator of which is the total number of Company Securities directly or indirectly owned by the Sponsor Group as of the close of business on the day immediately prior to the Tag-Along Notice Date. 
 (b) The Sponsor Group shall provide each
Tag-Along Stockholder with written notice (the “Tag-Along Sale Notice”) prior to the proposed date of the consummation of the Tag-Along Sale (the “Tag-Along Sale Date”). Each Tag-Along Sale Notice shall set forth: (i) the name and address
of each proposed transferee in the Tag-Along Sale; (ii) the number of Company Securities that are proposed to be Transferred directly or indirectly by the Sponsor Group pursuant to the Tag-Along Sale; (iii) the proposed amount and form of consideration to be paid for such securities and the terms and conditions of payment offered by each proposed transferee; (iv) the aggregate number of
Company Securities directly or indirectly held by the Sponsor Group as of the close of business on the day immediately prior to the date of the Tag-Along Sale Notice (the “Tag-Along Notice Date”); (v) the Tag-Along Stockholder’s Tag-Along Allotment, assuming the
Tag-Along Stockholder elected to sell the maximum number of Shares permissible; and (vi) the anticipated Tag-Along Sale Date. For the avoidance of doubt, a Tag-Along Stockholder shall participate in the Tag-Along Sale at the same price per share of Stock and upon the same terms and conditions of the offer so accepted by the
Sponsor Group, including representations, warranties, covenants, indemnities and agreements substantially similar to those to be made by the Sponsor Group (except that, (A) the only representations, warranties or covenants that any Management
Stockholder would be required to make are with respect to his, her or its own ownership of the Shares to be sold by him, her or it (including his, her or its ability to convey title free and clear of liens, encumbrances or adverse claims and
reasonable covenants regarding confidentiality, publicity and similar matters) and (B) if the Tag-Along Sale involves any non-cash consideration, any rights or
restrictions with respect to the non-cash consideration payable to each such member may be proportionate to the relative size of ownership of such non-cash
consideration, such as entitlements to board seats or demand registration rights; provided, that (x) all representations, warranties and indemnities shall be made by the Sponsor Group and such members of a Management Stockholder Group
transferring Shares pursuant to this Section 4 severally and not jointly, and (y) the liability of any member of a Management Stockholder Group would be limited to the lesser of such member’s pro rata share and
the aggregate proceeds received by such member; provided, further that any such liability of such member shall be satisfied first by the return of any cash proceeds received by such member (including the cash proceeds from the sale of
any securities or other non-cash consideration received by such member) and second by the return of any non-cash consideration (including securities) received by such
member. 

  
 - 13 - 













 (c) Any Tag-Along Stockholder wishing to participate
in the Tag-Along Sale shall provide written notice (the “Tag-Along Notice”) to the Sponsor Group and the Company no less than fifteen (15) Business
Days after receipt of the Tag-Along Notice irrevocably electing to participate in such Tag-Along Sale. The Tag-Along Notice shall
set forth the number of Shares that such Tag-Along Stockholder elects to include in the Tag-Along Sale, which may be less than or equal to, but which shall not exceed,
such Tag-Along Stockholder’s Tag-Along Allotment. The Tag-Along Notice given by any
Tag-Along Stockholder shall constitute such Tag-Along Stockholder’s irrevocable and binding agreement to sell the Shares specified in the Tag-Along Notice on the terms and conditions applicable to the Tag-Along Sale; provided, that in the event that there is any material adverse change in the terms and
conditions of such Tag-Along Sale applicable to the Tag-Along Stockholder (including any material decrease in the purchase price that occurs other than pursuant to an
adjustment mechanism set forth in the agreement relating to the Tag-Along Sale) after such Tag-Along Stockholder gives its
Tag-Along Notice, then the Tag-Along Stockholder shall have the right to withdraw from participation in the Tag-Along Sale with
respect to all of its Shares affected thereby. If the proposed transferee does not agree to consummate the acquisition of all of the Shares requested to be included in the Tag-Along Sale by any Tag-Along Stockholder on substantially identical material terms and conditions as are applicable to the Sponsor Group (and, in any event, at a per share price not less than that received by the Sponsor Group, except
as the purchase price may be adjusted pursuant to any agreement relating to the relevant Tag-Along Sale), then the Sponsor Group shall not consummate the Tag-Along Sale
of any of its shares of Stock to such transferee unless the shares of Stock of the Sponsor Group and the Tag-Along Stockholders to be Transferred are reduced or limited pro rata in proportion to the respective
number of shares of Stock actually held, directly or indirectly, by the Sponsor Group and the Tag-Along Stockholders and all other material terms and conditions of the
Tag-Along Sale are substantially identical for the Sponsor Group and the Tag-Along Stockholders (including the same price per share received by both the Sponsor Group
and the Tag-Along Stockholders). 
 (d) If a Tag-Along Notice
from any Tag-Along Stockholder is not received by the Sponsor Group prior to the lapse of the ten Business Day (10 Business Day) period specified above, the Sponsor Group shall have the right to consummate the
Tag-Along Sale without the participation of such Tag-Along Stockholder, who shall be deemed to have waived his or her rights hereunder, but only on terms and conditions
which are no more favorable in any material respect to the Sponsor Group (and, in any event, at no greater a per share purchase price, except as the purchase price may be adjusted pursuant to any agreement relating to the relevant Tag-Along Sale) than as stated in the Tag-Along Sale Notice, and only if such Tag-Along Sale is consummated on a date within ninety
(90) days after the proposed Tag-Along Sale Date. If such Tag-Along Sale is not consummated within such ninety-day (90-day) period, the shares or interests that were to be subject to such Tag-Along Sale thereafter shall continue to be subject to all of the restrictions contained in this
Section 4. 

  
 - 14 - 













 (e) On the Tag-Along Sale Date, each Tag-Along Stockholder shall deliver a certificate or certificates (if certificated) for the Shares to be sold by such Tag-Along Stockholder in connection with the Tag-Along Sale, with undated stock powers duly endorsed in blank for Transfer by the registered owner or owners thereof, to the transferee free and clear of all liens, encumbrances and restrictions, in the manner
and at the address indicated in the Tag-Along Sale Notice, against delivery of the purchase price for such Shares. Each Tag-Along Stockholder shall reimburse the Sponsor
Group for its proportionate share (based on the consideration received) of the reasonable out-of-pocket costs and expenses incurred by the Sponsor Group in connection
with any such Tag-Along Sale. 
 (f) The provisions of this Section 4 shall
apply regardless of the form of consideration received in the Tag-Along Sale; provided, that, in the event the consideration to be paid in exchange for shares of Stock in a proposed Tag-Along Sale includes any securities, and the receipt thereof by a Tag-Along Stockholder would require (as determined by the Sponsor Group in good faith upon the advice of
its counsel) under applicable law (x) the registration or qualification of such securities or of any Person as a broker or dealer or agent with respect to such securities where such registration or qualification is not otherwise required by the
receipt of such securities by the Sponsor Group or (y) the provision to any such Tag-Along Stockholder of any specified information regarding such securities or the issuer thereof that is not otherwise
required to be provided for in connection with the Tag-Along Sale, then, in either case of (x) or (y), in lieu of receiving such securities (as may be required by the Sponsor Group, in its sole
discretion), the member of such Management Stockholder Group may, at the Sponsor Group’s direction, receive cash consideration equal to the fair market value of such securities. 

(g) In lieu of the Sponsor Group providing to any Tag-Along Stockholder the opportunity to participate
proportionately in such Tag-Along Sale in accordance with this Section 4, at the election of the Sponsor Group, the Company may instead afford to such
Tag-Along Stockholder the right to cause the Company to redeem for cash a number of Shares up to such Tag-Along Stockholder’s
Tag-Along Allotment at the same price per Share received by the Sponsor Group in such Tag-Along Sale (or, if the Sponsor Group received securities in connection with
such Tag-Along Sale, cash per Share equal to the fair market value of such securities (plus cash, if any) per Share received by the Sponsor Group, as such value is determined by the Sponsor Group in its sole
discretion). The Sponsor Group and the Company shall provide such Tag-Along Stockholder with written notice of such redemption right (a “Redemption Notice”), which Redemption Notice may be
provided either prior to or within one (1) month after the consummation of the applicable Tag-Along Sale and shall include the anticipated date of such redemption, which date shall be no later than ninety
(90) days after the consummation of the Tag-Along Sale. Any such Tag-Along Stockholder wishing to participate in such redemption shall provide written notice to the
Sponsor Group and the Company, no less than fifteen (15) Business Days after receipt of by such Tag-Along Stockholder of the Redemption Notice, irrevocably electing to participate in such redemption. For
the avoidance of doubt, in the event the Sponsor Group elects to provide any such Tag-Along Stockholder the redemption rights set forth in this Section 4(g), such
Tag-Along Stockholder shall not be entitled to receive a Tag-Along Sale Notice or otherwise participate in the Tag-Along Sale as
provided pursuant to the other provisions of this Section 4. Furthermore, in the event a Redemption Notice is provided prior to the consummation of the applicable Tag-Along Sale, and such Tag-Along Sale is not consummated by the Sponsor Group, the redemption right provided in such Redemption Notice shall automatically expire and be of no force and effect.

 (h) The rights set forth in this Section 4 shall terminate
immediately prior to the earlier to occur of a Change in Control and the consummation of the Initial Public Offering. 
 5. Call
Rights. 
 (a) Each member of a Management Stockholder Group agrees that the Company and the Sponsor Group, collectively, will each have
a call right (the “Call Right”) on the Shares (including any Shares issued following a Termination pursuant to the exercise of Options or otherwise) and vested Options held by his, her or its Management Stockholder Group after
either a Termination or a Restrictive Covenant Violation with respect to the applicable Management Stockholder (the “Callable Equity”) as set forth in this Section 5. Upon either a Termination or a
Restrictive Covenant Violation with respect to a Management Stockholder (any such event, a “Call Event”), the Company may exercise the Call Right with respect to all or any portion of the Callable Equity of such Management
Stockholder’s Management Stockholder Group by one or more written notices (each, a “Call Right Notice”) delivered to the Management Stockholder at any time during the period commencing on the date of Termination or the date on
which the Board acquires actual knowledge of the occurrence of the Restrictive Covenant Violation, as applicable, and ending on the date which is three hundred and sixty-five (365) days after the later of (x) the date of Termination or the
date on which the Board acquires actual knowledge of the occurrence of the Restrictive Covenant Violation, as applicable, and (y) for each Share acquired upon the exercise of an Option or similar purchase right, the date on which such Share was
acquired (the date such notice is given being, the “Call Exercise Date”). Upon the giving of a Call Right Notice, the Company will be obligated to purchase and the Management Stockholder Group will be obligated to sell all (or any
lesser portion indicated in the Call Right Notice) of the Callable Equity for the consideration calculated as set forth below. If the Company fails to exercise the Call Right with respect to a particular Call Event, then the Sponsor Group (or any
Affiliate of the Sponsor Group as such may be assigned to by the Sponsor Group) may exercise such Call Right within thirty (30) days after the expiration of the aforesaid three hundred and sixty-five
(365)-day period by giving one or more written notices (each, a “Sponsor Group Call Right Notice”) to the Management Stockholder that the Sponsor Group (or Affiliate thereof) is exercising the
Call Right (the date such notice is given being, the “Sponsor Group Call Exercise Date”). Upon the giving of a Sponsor Group Call Right Notice, the Sponsor Group will be obligated to purchase and the Management Stockholder Group
will be obligated to sell all (or any lesser portion indicated in the aforesaid notice) of the Callable Equity for the consideration calculated as set forth below. Notwithstanding anything herein to the contrary, if determined to be necessary by the
Company in order to avoid an additional compensation expense, in no event shall the Company or the Sponsor Group (or any Affiliate of the Sponsor Group) be entitled to deliver any Call Right Notice or Sponsor Group Call Right Notice, as applicable,
with respect to any Shares (including any Shares issued upon the exercise of an Option or similar purchase right in respect of any other Award) unless and until such Shares have been issued, vested (if applicable) and outstanding for at least six
(6) months. 
 (i) In the case of either (x) a Termination for Cause or (y) a Restrictive Covenant Violation:

 (A) With respect to any Shares that are not Purchased Shares, the consideration will be equal to the lesser of
(1) the Cost of such Shares and (2) the Fair Market Value of such Shares on the Call Exercise Date or the Sponsor Group Call Exercise Date, as applicable; 

  
 - 16 - 













 (B) With respect to any Purchased Shares, the consideration will be equal to
the Fair Market Value of such Shares on the Call Exercise Date or the Sponsor Group Call Exercise Date, as applicable; and 

(C) All vested Options shall automatically be terminated in accordance with the Plan; 

(ii) In the case of a Termination for any reason other than for Cause: 

(A) With respect to any Shares that are not Purchased Shares, the consideration will be equal to the Fair Market Value of such
Shares on the Call Exercise Date or the Sponsor Group Call Exercise Date, as applicable; 
 (B) With respect to any Purchased
Shares, the consideration will be equal to (i) in the case of a Termination (other than a Termination resulting from the Management Stockholder’s resignation without Good Reason) that occurs prior to second anniversary of the date on which
such Purchased Shares were acquired, the higher of (x) the Cost of such Shares and (y) the Fair Market Value of such Shares, and (ii) in the case of any other Termination, the Fair Market Value of such Shares on the Call Exercise Date
or the Sponsor Group Call Exercise Date, as applicable; and 
 (C) With respect to any vested Options, the consideration will
be equal to the product of (1) the excess, if any, of the Fair Market Value of a Share subject to such vested Option on the Call Exercise Date or the Sponsor Group Call Exercise Date, as applicable, over the exercise price per Share of such
vested Option, and (2) the number of Shares subject to such vested Option, which vested Options shall be terminated in exchange for the payment of such consideration; provided, that if the exercise price per Share of such vested Option
is greater than the Fair Market Value of a Share on the Call Exercise Date or the Sponsor Group Call Exercise Date, as applicable, such vested Option shall be automatically terminated without any payment of consideration in respect thereof. 

(b) The closing for all purchases and sales of Callable Equity pursuant to this Section 5 will be at the principal
executive offices of the Company within thirty (30) days after the Call Exercise Date or the Sponsor Group Call Exercise Date, as the case may be. The purchase price for the Callable Equity will be paid to the Management Stockholder (or his or
her estate or beneficiary, as applicable) in cash, by cashier’s check or by wire transfer of funds; provided, that if the Company or the Sponsor Group, as applicable, exercises the Call Right following a (i) a Termination by the
Service Recipient for Cause or (ii) a Restrictive Covenant Violation, the Company or the Sponsor Group, as applicable, shall be permitted to issue a promissory note equal to the aggregate purchase price, with such promissory note having a
maturity date that does not exceed three (3) years from the date of the closing of such purchase, bearing simple interest of not less than the Prime Rate in effect on the date of such purchase, and


  
 - 17 - 













 
being payable as to interest in equal monthly installments during the term of the note and as to principal on the maturity date, subject to full and immediate payment upon the earlier to occur of
a Change in Control or the consummation of the Initial Public Offering. The Management Stockholder Group will cause the Callable Equity to be delivered to the Company or the Sponsor Group, as the case may be, at the closing free and clear of all
liens, claims, charges or encumbrances of any kind, other than those which continue to apply pursuant to the terms of this Agreement. The Management Stockholder Group will take all such actions and deliver all such documents and instruments as the
Company or the Sponsor Group, as the case may be, reasonably requests to vest in the Company or the Sponsor Group, respectively, title to the Callable Equity free of any lien, claim, charge, restriction or encumbrance incurred by or through the
Management Stockholder Group. 
 (c) Notwithstanding anything in this Section 5 to the contrary, if (i) there
exists and is continuing a default or an event of default on the part of any member of the Company Group under any loan, guarantee or other agreement under which any member of the Company Group has borrowed money or if the repurchase of Callable
Equity would result in a default or an event of default on the part of any member of the Company Group under any such agreement or if a repurchase would not be permitted under the Delaware General Corporation Law (or if the Company reincorporates in
another state, the business corporation law of such state) or any federal or state securities laws or regulations (each such occurrence being an “Event”) and (ii) the Sponsor Group has not elected to acquire all Callable Equity
which the Company and the Sponsor Group have a right to purchase pursuant to this Section 5, the Company will, to the extent it has exercised its Call Right and subject to the rescission rights below, in order to complete
the purchase of any Callable Equity pursuant to this Section 5, deliver to the Management Stockholder (A) a cash payment for any amounts payable pursuant to this Section 5 that would not cause
an Event that prohibits the Company from purchasing Callable Equity for cash, and (B) a promissory note with a principal amount equal to the amount payable under this Section 5 that was not paid in cash, having terms
acceptable to the Company’s (and its Affiliates’, as applicable) lenders and permitted under the Company’s (and its Affiliates’, as applicable) debt instruments but which in any event (x) shall be mandatorily repayable
promptly after and to the extent that an Event no longer prohibits the payment of cash to the Management Stockholder pursuant to this Agreement; (y) shall bear interest at a rate equal to the sum of the effective rate of interest in respect of
the Company’s (or Affiliate’s, if applicable) primary revolving credit facility and two percent (2%) and (z) shall be subject to full and immediate payment upon the earlier to occur of a Change in Control or the consummation of the
Initial Public Offering. In lieu thereof, the Company, in its sole discretion, may rescind the exercise of such Call Right, in which case, the period upon which the Call Right may be exercised by the Company shall be tolled until thirty
(30) days following the date on which there ceases to be any Event, and the Company may exercise the Call Right at any time during such thirty (30) day period pursuant to this Section 5. 

(d) Notwithstanding anything in this Section 5 to the contrary, in the event that it has been determined necessary by
the Company in order to avoid an additional compensation expense with respect to the Call Right for vested Options, the Management Stockholder Group may be required by the Company, upon prior written approval of the Board, to exercise, on one
occasion, all of the vested Options then held by such Management Stockholder Group using a net exercise method whereby the number of Shares that would 

  
 - 18 - 













 
otherwise be received upon the exercise of such Options shall be reduced by that number of Shares (i) having an aggregate Fair Market Value equal to the sum of the aggregate exercise price
for such Options, plus (ii) the number of Shares having an aggregate Fair Market Value equal to the aggregate amount of the applicable withholding taxes which the Company is required to withhold in respect of the income recognized as a
consequence of the exercise of the Options, and the remaining Shares received upon such exercise shall be subject to purchase by the Company upon delivery of a Call Right Notice during the thirty (30) day period following the date on which such
Shares have been held by such Management Stockholder Group for at least six (6) months, and otherwise in accordance with this Section 5. 

(e) The rights set forth in this Section 5 shall terminate upon the Lapse Date. 

6. Put Rights. 
 (a) The
Company agrees that each Management Stockholder will have a put right (the “Put Right”) on the Shares (including any Shares issued following a Put Event pursuant to the exercise of Options or otherwise) and vested Options held by
his or her Management Stockholder Group after a Put Event (the “Puttable Equity”) as set forth in this Section 6. Upon the Termination of a Management Stockholder due to his or her death or Disability
(each, a “Put Event”), the Management Stockholder’s Management Stockholder Group may exercise the Put Right with respect to all and not less than all of the Puttable Equity by a single written notice (a “Put Right
Notice”) delivered to the Company at any time during the period commencing on the date of such Put Event and ending on the date which is one hundred and ninety (190) days following the later of (x) the date of such Put Event and
(y) for each Share acquired upon the exercise of an Option or similar purchase right, the date on which such Share was acquired (the date such notice is given being, the “Put Exercise Date”). Upon the giving of a Put Right
Notice, the Company will be obligated to purchase and the Management Stockholder Group will be obligated to sell all and not less than all of the Puttable Equity for the consideration calculated as set forth below. Notwithstanding anything herein to
the contrary, if determined to be necessary by the Company in order to avoid an additional compensation expense, in no event shall the Management Stockholder Group be entitled to deliver the Put Right Notice with respect to any Shares (including any
Shares issued upon the exercise of an Option or similar purchase right in respect of any other Award) unless and until such Shares have been issued, vested (if applicable) and outstanding for at least six (6) months. 

(i) With respect to any Shares, the consideration will be equal to the Fair Market Value of such Shares on the Put Exercise
Date; and 
 (ii) With respect to any vested Options, the consideration will be equal to the product of (A) the excess,
if any, of the Fair Market Value of a Share subject to such vested Option on the Put Exercise Date, over the exercise price per Share of such vested Option, and (B) the number of Shares subject to such vested Option, which vested Options shall
be terminated in exchange for the payment of such consideration; provided, that if the exercise price per Share of such vested Option is greater than the Fair Market Value of a Share on the Put Exercise Date, such vested Option shall be
automatically terminated without any payment of consideration in respect thereof. 

  
 - 19 - 













 (b) The closing for all purchases and sales of Puttable Equity pursuant to this
Section 6 will be at the principal executive offices of the Company within thirty (30) days after the Put Exercise Date. The purchase price for the Puttable Equity will be paid to the Management Stockholder (or his or
her estate or beneficiary, as applicable) in cash, by cashier’s check or by wire transfer of funds. The Management Stockholder Group will cause the Puttable Equity to be delivered to the Company at the closing free and clear of all liens,
claims, charges or encumbrances of any kind, other than those which continue to apply pursuant to the terms of this Agreement. The Management Stockholder Group will take all such actions and deliver all such documents and instruments as the Company
reasonably requests to vest in the Company title to the Puttable Equity free of any lien, claim, charge, restriction or encumbrance incurred by or through the Management Stockholder Group. 

(c) Notwithstanding anything in this Section 6 to the contrary, if there exists and is continuing an Event, the
Company will, in order to complete the purchase of any Puttable Equity pursuant to this Section 6, deliver to the Management Stockholder (or his or her estate or beneficiary, as applicable) (i) a cash payment for any
amounts payable pursuant to this Section 6 that would not cause an Event that prohibits the Company from purchasing Puttable Equity for cash, and (ii) a promissory note with a principal amount equal to the amount
payable under this Section 6 that was not paid in cash, having terms acceptable to the Company’s (and its Affiliates’, as applicable) lenders and permitted under the Company’s (and its Affiliates’, as
applicable) debt instruments but which in any event (A) shall be mandatorily repayable promptly after and to the extent that an Event no longer prohibits the payment of cash to the Management Stockholder pursuant to this Agreement;
(B) shall bear interest at a rate equal to the sum of the effective rate of interest in respect of the Company’s (or Affiliate’s, if applicable) primary revolving credit facility and two percent (2%) and (C) shall be subject to
full and immediate payment upon the earlier to occur of a Change in Control or the consummation of the Initial Public Offering. 
 (d)
Notwithstanding anything in this Section 6 to the contrary, in the event it has been determined necessary by the Company in order to avoid an additional compensation expense with respect to the Put Right for vested Options,
the Management Stockholder Group may be required by the Company, upon prior written approval of the Board, to exercise, on one occasion, all of the vested Options then held by such Management Stockholder Group using a net exercise method whereby the
number of Shares that would otherwise be received upon the exercise of such Options shall be reduced by that number of Shares (i) having an aggregate Fair Market Value equal to the sum of the aggregate exercise price for such Options, plus
(ii) the number of Shares having an aggregate Fair Market Value equal to the aggregate amount of the applicable withholding taxes which the Company is required to withhold in respect of the income recognized as a consequence of the exercise of
the Options, and the remaining Shares received upon such exercise shall be subject to purchase by the Company upon delivery of the Put Right Notice during the thirty (30) day period following the date on which such Shares have been held by such
Management Stockholder Group for at least six (6) months, and otherwise in accordance with this Section 6. 

(e) The rights set forth in this Section 6 shall terminate upon the Lapse Date.

 7. “Piggyback” Registration Rights. 

(a) Incidental Registration. After the closing of an Initial Public Offering, if the Company files a registration statement under the
Securities Act in connection with a proposed Public Offering and any of the Sponsor Group are registering shares of Stock in such proposed Public Offering, then each Management Stockholder Group, the Management Stockholder of which is then subject
to the reporting requirements of Section 16 of the Exchange Act shall have the right (the “Piggyback Right”) to include in such proposed Public Offering up to the number of Registrable Shares equal to (i) the aggregate
number of Registrable Shares owned by such Management Stockholder Group multiplied by (ii) a fraction (A) the numerator of which is equal to the aggregate number of Company Securities directly or indirectly held by Sponsor Group to be
included in such proposed Public Offering and (B) the denominator of which is the aggregate number of Company Securities directly or indirectly held by Sponsor Group (the “Piggyback Pro-Rata
Portion”). In the event that a proposed Public Offering gives rise to a Piggyback Right, the Company will give written notice to the Management Stockholders. Upon written request of any Management Stockholder given within ten
(10) Business Days after mailing of any such notice from the Company, the Company will, except as herein provided, cause up to the Piggyback Pro-Rata Portion of such Management Stockholder Group’s
Registrable Shares that have been requested by such Management Stockholder to be included in the registration to be included in such registration statement; provided, that nothing herein shall prevent the Company from, at any time, abandoning
or delaying any registration for any reason or no reason. 
 (b) Limitations. If any Public Offering pursuant to
Section 7(a) shall be underwritten on a firm commitment basis, in whole or in part, the Company may require that the Registrable Shares requested for inclusion pursuant to Section 7(a) be included
in such Public Offering on the same terms and conditions as the securities otherwise being sold through the underwriters. If the underwriter of such Public Offering determines that marketing factors (including an adverse effect on the per share
offering price) require a limitation of the number of Registrable Shares to be underwritten in such Public Offering then, notwithstanding any contrary provision in Section 7(a), the underwriter may limit the number of
shares that would otherwise be included in such Public Offering by excluding any or all Registrable Shares from such Public Offering. The number of Registrable Shares to be included in such Public Offering shall be allocated in the following manner:
(i) if such registration has been initiated by one or more of the Company’s stockholders holding demand registration rights with the Company pursuant to the Registration Rights Agreement or any other registration rights agreement or any
similar agreements, then (A) first, the number of shares of Stock requested to be registered by such initiating stockholder(s) and any other holder(s) of the Company’s securities which are entitled to sell pursuant to the Registration
Rights Agreement or any other registration rights agreement or any similar agreements, pro rata in accordance with the number of shares of Stock owned by each such stockholder or other holder of Stock, and (B) second, the number of shares of
Stock that are proposed to be sold by the Company for its own account; or (ii) if such registration has been initiated by the Company, then (A) first, the number of shares of Stock that are proposed to be sold by the Company for its own
account, (B) second, the number of shares of Stock requested to be registered by any holder(s) of the Company’s securities which are entitled to sell pursuant to the Registration Rights Agreement, pro rata in accordance with the number of
shares of Stock owned by each such stockholder or other holder of Stock and (C) third, the number of shares of Stock requested to be registered by any holder(s) of the Company’s securities which are entitled to sell pursuant any other
registration rights agreement or similar agreements (including the Management Stockholder Groups hereunder), pro rata in accordance with the number of shares of Stock owned by each such stockholder or other holder of Stock. 

  
 - 21 - 













 (c) Information. It shall be a condition precedent to the obligation of the Company
to take any action pursuant to this Agreement in respect of the Registrable Shares which are to be registered at the request of any Management Stockholder that such Management Stockholder shall promptly furnish to the Company such information
regarding the Registrable Shares held by his or her Management Stockholder Group and the intended method of disposition thereof, and shall enter into such underwriting agreements (including customary representations, warranties, covenants,
indemnities and other agreements) and execute such other documents, in each case as the Company shall reasonably request in connection with such registration. 

(d) Suspension of Disposition. Each Management Stockholder Group agrees that, upon receipt of any notice from the Company that any
prospectus required to be delivered to a Management Stockholder Group pursuant to the Securities Act contains an untrue statement of a material fact or fails to state a material fact necessary to make the statements therein, in the light of the
circumstances in which they were made, not misleading, such Management Stockholder Group will forthwith discontinue disposition of Registrable Shares pursuant to the registration statement covering such Registrable Shares until such Management
Stockholder Group receives from the Company a corrected prospectus, and, if so directed by the Company, such Management Stockholder Group will deliver to the Company all copies, other than permanent file copies, then in such Management Stockholder
Group’s possession, of the prospectus covering such Registrable Shares current at the time of receipt of such notice. 
 (e)
Expenses. With respect to each inclusion of Registrable Shares in a registration statement pursuant to Section 7(a) hereof, the Company shall bear the following fees, costs and expenses: all registration, filing and
listing fees, printing expenses, fees and disbursements of counsel for the Company, fees and disbursements of accountants for the Company and all legal fees and disbursements and other expenses of complying with state securities or blue sky laws of
any jurisdictions in which the securities to be offered are to be registered or qualified and any fees and expenses for any special audits incidental to or required by a registration contemplated by this Section 7. Fees and
disbursements of counsel for the transferring Management Stockholder Groups, fees and disbursements of accountants for the Management Stockholder Groups, underwriting discounts and selling commissions, transfer taxes and any other expenses incurred
by the Management Stockholder Groups not expressly included above shall be borne by the applicable Management Stockholder Groups. 
 (f)
Transfer Restriction Waiver. Notwithstanding anything in this Section 7 to the contrary, in lieu of the Piggyback Rights in connection with any Public Offering in which such rights would otherwise be available, the
Board, in its sole discretion, may elect to waive the restrictions on Transfer contained in Section 2(a) with respect to all or any portion of the number of Registrable Shares that would have been subject to such Piggyback
Rights in connection with such Public Offering.

 (g) Lock-up Agreement. If any registration of
Stock shall be in connection with an underwritten public offering, each Management Stockholder Group, the Management Stockholder of which is then subject to the reporting requirements of Section 16 of the Exchange Act, agrees, if requested by
the underwriter, to enter into an agreement not to, and shall use its best efforts to cause its Affiliates not to, effect any sale or distribution (except as a participant in such underwritten public offering), including any sale pursuant to Rule
144 under the Securities Act, of any equity securities of the Company, or of any security convertible into or exchangeable or exercisable for any equity security of the Company (in each case, except as a participant in such underwritten public
offering), during the seven (7) days prior to, and during the one hundred eighty (180) day period (or such shorter period as the managing underwriters may require or permit) beginning on the date of the final prospectus (or final
prospectus supplement if the offering is made pursuant to a shelf registration) pursuant to which such Public Offering shall be made; provided, that the restriction on the public sale or distribution of equity securities contained in this
Section 7(g) shall only apply to a holder of Registrable Shares if the same restriction is also applied to directors, officers and 1% shareholders of the Company; provided further that, if any shares are proposed to be
released from the restriction on public sale or distribution in this Section 7(g), then the shares so released shall be allocated on a pro rata basis among all of the Registrable Shares subject to the provisions of this
Section 7(g). 
 8. Pro Rata Repurchases 

(a) In the event the Board is requiring the repurchase of shares of Company Securities directly or indirectly from each member of the Sponsor
Group for cash (a “Repurchase”), subject to the requirements of clause (b) below, then the Company may require each member of each Management Stockholder Group to sell, transfer and deliver to the Company, free and clear of all
liens, such number of shares of Stock as is approved by the Board, at the same price per share of Stock that is mutually agreed by the Company and the Sponsor Group, in each case as specified in a written notice by the Company to each Management
Stockholder (a “Repurchase Notice”). The closing of the Repurchase will occur at the time and place specified in the Repurchase Notice, but in no event earlier than 5 Business Days following the delivery of the Repurchase Notice.

 (b) The Company shall not make any Repurchase from a member of a Management Stockholder Group unless (i) such Repurchase is required
of all members of all Management Stockholder Groups together with all members of the Sponsor Group on a pro rata basis in accordance with their respective Percentage Interests, (ii) the Repurchase of each share of Stock from a member of
a Management Stockholder Group as well as a member of the Sponsor Group is effected at the same price per share (i.e., no disparate prices for shares) and (iii) following such Repurchase the Company and its subsidiaries would comply with the
Foreign Ownership Limitations.

member of the Company Group in effect from time to time, as the same shall be amended from time to time, provides that a specific restrictive covenant(s) contained in such agreement or arrangement will apply, instead of a specifically identified
restrictive covenant(s) contained in this Section 17(a), to any Awards or Shares held by the Management Stockholder, in which case such restrictive covenant(s) will be deemed to be the applicable restrictive covenant(s) for
this Section 17(a): 

  
 - 28 - 













 (i) During the term of the Management Stockholder’s employment with any
member of the Company Group and solely if Management Stockholder holds the position of vice president or any more senior position immediately prior to the date of termination, for a period of one (1) year thereafter, the Management Stockholder
may not, within the country in which the Management Stockholder’s principal office or work location with the Company Group was located on the date of Termination, whether as owner, manager, officer, director, employee or otherwise, be engaged
or employed by any entity that directly competes with the business of any member of the Company Group, to perform duties and responsibilities that are the same or substantially related to the duties and responsibilities that the Management
Stockholder performed for the Company Group at any time during the twenty-four (24) months prior to the date of Termination. Ownership by the Management Stockholder of not more than one percent (1.0%) of the shares of any corporation having a
class of equity securities actively traded on a national securities exchange shall not be deemed, in and of itself, to violate the prohibitions set forth in this Section 17(a)(i); 

(ii) During the term of the Management Stockholder’s employment with any member of the Company Group and for a period of
one (1) year thereafter, the Management Stockholder may not, directly or indirectly, solicit the business of, or accept business from any Customer of any member of the Company Group on the date of Termination, unless the business being
solicited or accepted is not in competition with or substantially similar to any member of the Company Group’s business; 

(iii) During the term of the Management Stockholder’s employment with any member of the Company Group and for a period of
one (1) year thereafter, the Management Stockholder may not directly or indirectly, solicit or induce (or attempt to solicit or induce) to leave the employ of any member of the Company Group for any reason whatsoever, any Person employed by any
member of the Company Group at the time of (or within the six months prior to) the date of Termination; 
 (iv) During the
term of the Management Stockholder’s employment with any member of the Company Group and for a period of one (1) year thereafter, the Management Stockholder may not directly or indirectly, employ or hire any Person employed by any member
of the Company Group at the time of (or within the six months prior to) the date of Termination, whom the Management Stockholder supervised or with whom the Management Stockholder had other material/significant business interactions during the one
(1) year period prior to the date of Termination; and 
 (v) The Management Stockholder may not at any time make public,
disclose, divulge, furnish, release, transfer, sell or otherwise make available to any Person any Confidential Information, or otherwise use or disclose it or allow it to be used or disclosed for any purpose, other than as may be permitted under
this Agreement. Notwithstanding the foregoing, the Management Stockholder may disclose Confidential Information without violating this Agreement if (A) disclosure is required to comply with applicable law, a valid court order or any
administrative law order or decree; (B) the Management Stockholder gives the Company advance written notice of the required disclosure so that the Company may, if it wishes, seek an appropriate protective order; (C) the Management
Stockholder discloses only that portion of the information as is, based on the advice of the Management Stockholder’s counsel, legally required to be so disclosed, and (D) the Management Stockholder requests that any disclosed information
be afforded confidential treatment to the greatest extent possible. 

  
 - 29 - 













 (b) Nothing in this Agreement shall prohibit or impede the Management Stockholder from
communicating, cooperating or filing a complaint with any U.S. federal, state or local governmental or law enforcement branch, agency or entity (collectively, a “Governmental Entity”) with respect to possible violations of any U.S.
federal, state or local law or regulation, or otherwise making disclosures to any Governmental Entity, in each case, that are protected under the whistleblower provisions of any such law or regulation; provided, that in each case such
communications and disclosures are consistent with applicable law. The Management Stockholder does not need the prior authorization of (or to give notice to) the Company Group regarding any such communication or disclosure. The Management
Stockholder understands and acknowledges that an individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that is made (i) in confidence to a Federal, State, or
local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of the law; or (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under
seal. The Management Stockholder understands and acknowledges further that an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual
and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal; and does not disclose the trade secret, except pursuant to court order. Notwithstanding the foregoing, under
no circumstance is the Management Stockholder authorized to disclose any information covered by the Company Group’s attorney-client privilege or attorney work product without the prior written consent of the Company’s General Counsel. 

(c) The Management Stockholder specifically acknowledges and agrees that (x) the Company Group’s business competes on a global basis,
(y) the provisions of this Section 17, including the geographic and time limitations applicable thereto, are reasonable and necessary to protect the legitimate interests of the Company Group and that the Management
Stockholder desires to agree to the provisions of this Section 17, and (z) the provisions of this Section 17 are sufficiently tailored and do not prevent Management Stockholder from working in
the vitamins, minerals, and health supplements industry. In the event that (i) any of the provisions of this Section 17 should ever be held to exceed the time, scope or geographic limitations permitted by applicable
law, it is the intention of the parties that such provision be reformed to reflect the maximum time, scope and geographic limitations that are permitted by law or (ii) the Management Stockholder resides in the state of California or the
restrictions set forth in Section 17(a)(i), (ii), (iii) and/or (iv) would otherwise violate the applicable law of any jurisdiction in which a Management Stockholder resides, then the restrictions
set forth in Section 17(a)(i), (ii), (iii) and/or (iv) shall be deemed not apply to such Management Stockholder and the remaining provisions of this Agreement and this
Section 17 shall not be in any way impaired; provided, that, notwithstanding the foregoing in this clause (ii), any act that would be in violation of Section 17(a)(i), (ii),
(iii) and/or (iv) shall be deemed a Call Event and the Company shall be entitled to take any actions, and to any remedies, pursuant to a Call Event, with the Management Stockholder being treated in the same manner as if the
Management Stockholder had been Terminated for Cause. 

  
 - 30 - 













 (d) Any Management Stockholder receiving grants of Options that are subject to the Plan and
this Agreement acknowledges and agrees that the consideration provided by the Company Group in exchange for this Agreement, including the provisions of this Section 17, includes the Management Stockholder’s right to
exercise such Options, whether or not exercised. Accordingly, the provisions of this Section 17 are intended to and shall survive the expiration of any such Options. 

(e) The Management Stockholder acknowledges and agrees that, owing to the special, unique and extraordinary nature of the matters covered by
this Section 17, in the event of any breach by the Management Stockholder of any of the provisions hereof, the Company Group would suffer substantial and irreparable injury, which could not be fully compensated by monetary
award alone, and the Company Group would not have adequate remedy at law. Therefore, the Management Stockholder agrees that, in such event, the Company Group will be entitled to temporary and/or permanent injunctive relief against the Management
Stockholder, without the necessity of proving actual damages or of posting bond to enforce any of the provisions of this Section 17, and the Management Stockholder hereby waives the defenses, claims, or arguments that the
matters are not special, unique, and extraordinary, that the Company must prove actual damages, and that the Company has an adequate remedy at law. 

(f) The Management Stockholder agrees to disclose Section 17 of this Agreement and any related provisions to any of
the Management Stockholder’s future employers for the purpose of providing notice of the post-employment restrictions contained herein. The Management Stockholder further agrees, upon the Company’s request, to inform the Company of the
name and address of each subsequent employer that the Management Stockholder may have or any business with which the Management Stockholder may be involved, directly or indirectly, within the two (2)-year period following the date of Termination.

 (g) For the avoidance of doubt, the provisions of this Section 17 shall apply in addition to (and shall not be
limited by the provisions of) any other confidentiality, non-competition, non-solicitation or similar covenants of the Management Stockholder pursuant to any employment,
separation, consulting, or similar agreement or arrangement between such Management Stockholder and any member of the Company Group in effect from time to time, as the same shall be amended from time to time, such that the longest and broadest of
such restrictions shall apply (without duplication), unless such agreement or arrangement specifically provides otherwise. 
 18. Specific
Performance; Injunctive Relief. 
 The Parties hereto intend that each of the Parties hereto be given the right to seek damages or
specific performance in the event that any other Party hereto fails to perform such Party’s obligations hereunder. Therefore, if any Party shall institute any action or proceeding to enforce the provisions hereof, any Party against whom such
action or proceeding is brought hereby waives any claim or defense therein that the plaintiff Party has an adequate remedy at law. 

  
 - 31 - 













 19. Headings; Interpretation. 

The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof. In this
Agreement, unless the context otherwise requires, words in the singular number or in the plural number will each include the singular number and the plural number, words of the masculine gender will include the feminine and the neuter, and, when the
sense so indicates, words of the neuter will refer to any gender, and the term “including” shall be construed to be expansive rather than limiting in nature and to mean “including, without limitation”, 

20. Severability. 
 If any
one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions hereof shall not be in any way impaired, unless the provisions held invalid, illegal or unenforceable shall substantially impair the benefits of the remaining provisions hereof. 

21. Entire Agreement. 

This Agreement, the Plan, any award agreements thereunder entered into between the Company and the Management Stockholders and the other
documents referred to herein or delivered pursuant hereto contain the entire understanding of the Parties with respect to the subject matter hereof and thereof. There are no agreements, representations, warranties, covenants or undertakings with
respect to the subject matter hereof and thereof other than those expressly set forth herein and therein. 
 22. Further Assurances.

 Each of the Parties shall, and shall cause their respective Affiliates to, execute such documents and perform such further acts as may be
reasonably required or desirable to carry out or to perform the provisions of this Agreement. 
 23. Governing Law. 

All questions concerning the construction, validity, and interpretation of this Agreement shall be governed by and construed in accordance with
the domestic laws of the State of Delaware without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction
other than the State of Delaware. 
 24. Consent to Jurisdiction; No Jury Trial. 

Each of the Parties hereto submits to the jurisdiction of any state or federal court sitting in Delaware in any action or proceeding arising
out of or relating to this Agreement and agrees that all claims in respect of the action or proceedings may be heard and determined in any such court and hereby expressly submits to the personal jurisdiction and venue of such court for the purposes
hereof and expressly waives any claim of improper venue and any claim that such courts are an inconvenient forum. Any and all service of process and any other notice in any such 

  
 - 32 - 













 
action, suit or proceeding will be effective against any Party if given as provided herein. Nothing herein contained will be deemed to affect the right of any Party to serve process in any manner
permitted by law. EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVE ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, SUIT PROCEEDING OR COUNTERCLAIM BROUGHT BY ANY OF THEM AGAINST THE OTHERS IN ANY MATTERS ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS
AGREEMENT. 
 25. Additional Management Stockholders. 

Any Person that becomes party to a subscription agreement for Stock or Stock Equivalents or an Award Agreement (as defined in the Plan) after

substantially in the form attached as Exhibit A to the Plan, agreeing to be bound by the terms hereof (or only specific sections hereof) in the same manner as the other members of the Management Stockholder Groups. Each such joinder agreement
shall become effective upon its execution by the Company and such Person, and it shall not require the signature or consent of any other Party. Such supplemental agreement may modify some of the terms hereof as they affect such Person. 

26. Additional Members of Sponsor Group. 

Each member of the Sponsor Group agrees that it will cause any other Person that becomes a member of the Sponsor Group after the date hereof to

other members of the Sponsor Group. Each such additional countersignature to this Agreement shall become effective upon its execution by such Person, and it shall not require the signature or consent of any other Party. If a Person ceases to be a
member of the Sponsor Group, then such Person shall cease to have any rights or obligations hereunder; provided, that such Person shall remain liable for any breaches of this Agreement by it prior to the date it ceases to be a member of the
