MERRITT TOPCO, INC. 

AMENDED AND RESTATED 2017 STOCK OPTION PLAN 

1. Purpose of Plan. This Amended and Restated 2017 Stock Option Plan (this “Plan”) of Merritt Topco, Inc., a Delaware
corporation (the “Company”), is designed to provide incentives to such present and future employees, directors, officers, consultants or advisors of the Company or its subsidiaries (“Participants”), as may be
selected in the sole discretion of the Committee, through the grant of Options (as defined below) by the Company to Participants. Only those Participants who are employees of the Company or its Subsidiaries shall be eligible to receive incentive
stock options within the meaning of Section 422 of the Code. This Plan is a compensatory benefit plan within the meaning of Rule 701 of the Securities Act of 1933, as amended, and, unless and until the Company’s Common Stock is publicly
traded, the issuance of options to purchase shares of the Company’s Common Stock pursuant to this Plan and the issuance of shares of Common Stock pursuant to such options are, to the extent permitted by applicable federal securities laws,
intended to qualify for the exemption from registration under Rule 701 of the Securities Act.

Company shall have thirty (30) days in which to cure such breach. The Participant must actually terminate employment within fifteen (15) days following the expiration of the Company’s thirty

 (ii) the pro rata indirect economic interests of the holders of Option
Shares in the business of the Company, relative to each other and all other holders, directly or indirectly, of equity securities in the Company Group (other than those held by entities within the Company Group), are preserved; and 

(iii) the rights of the holders of Option Shares are preserved in all material respects (it being understood by way of
illustration and not limitation that the relocation of a covenant or restriction from one instrument to another shall be deemed a preservation if the relocation is necessitated, by virtue of any law or regulations applicable to the Company Group
following such Solvent Reorganization, as a result of any change in jurisdiction or form of entity in connection with the Solvent Reorganization; provided that such covenants and restrictions are retained in instruments that are, as nearly as

of the Company’s board of directors. 
 3. Grant of Options. The Committee shall have the right and power to grant to any
Participant such Options at any time prior to the termination of this Plan in such quantity, at such exercise price, which may be Fair Market Value or such other value as determined by the Committee and set forth in a written award agreement with
respect to an Option, and on such other terms and subject to such conditions that are consistent with this Plan and established by the Committee. Options granted under this Plan shall be subject to such terms and conditions and evidenced by
agreements as shall be determined from time to time by the Committee. Any Participant acquiring Common Stock pursuant to an Option shall be required to pay in full the exercise price related thereto, except as otherwise set forth in a written award
agreement with respect to an Option. 
 4. Administration of this Plan. The Committee shall have the power and authority to
prescribe, amend and rescind rules and procedures governing the administration of this Plan, including, but not limited to the full power and authority to (a) interpret the terms of this Plan, the terms of any Options granted under this Plan
and the rules and procedures established by the Committee governing any such 

  
 4 

 
Options, (b) determine the rights of any person under this Plan or the meaning of requirements imposed by the terms of this Plan or any rule or procedure established by the Committee,
(c) correct any defect or omission or reconcile any inconsistency in this Plan or in any Option granted hereunder, (d) determine whether any Options are subject to and/or comply with the requirements of Code Section 409A or the
regulations thereunder, and (e) make all other determinations and take all other actions necessary or advisable for the implementation and administration of this Plan. Each action of the Committee shall be binding on all persons.
Notwithstanding any provision to the contrary contained in this Plan or any separate written agreement between the Company and any Participant with respect to any Option pursuant to this Plan, any unvested Options that do not become vested
immediately prior to, or in connection with, any Sale of the Company shall be forfeited and cancelled with concurrent effect upon the consummation of any such transaction, and no Participant nor any other Person shall have any further rights or
obligations with respect to such forfeited Options. 
 It is the Company’s intent that, except as otherwise specifically provided in a
written award agreement with respect to an Option, the Options not be treated as a nonqualified deferred compensation plan that fails to meet the requirements of Section 409A(a)(2), (3) or (4) of the Code and that any ambiguities in
construction be interpreted in order to effectuate such intent. Options under this Plan shall contain such terms as the Committee determines are appropriate to be exempt from, or comply with, the requirements of Section 409A of the Code. In the
event that, after the issuance of an Option under this Plan, Section 409A of the Code or the regulations thereunder are amended, or the Internal Revenue Service or Treasury Department issues additional guidance interpreting Section 409A of
the Code, the Committee may modify the terms of any such previously issued Option to the extent the Committee determines that such modification is necessary to comply with the requirements of Section 409A of the Code. In no event whatsoever
shall the Company be liable for any additional tax, interest or penalty that may be imposed on any Participant by Code Section 409A or damages for failing to comply with Code Section 409A. 

5. Limitation on the Aggregate Number of Shares of Common Stock. The number of shares of Common Stock with respect to which Options may
be granted under this Plan (and which may be issued upon the exercise or payment thereof) shall not exceed, in the aggregate, 73,767.1650 shares of Common Stock (as such number is equitably adjusted pursuant to Section 8
hereof). If any Options expire unexercised or unpaid or are canceled, terminated or forfeited in any manner without the issuance of shares of Common Stock or payment thereunder, the shares with respect to which such Options were granted shall again
be available under this Plan. Similarly, if any shares of Common Stock issued hereunder upon exercise of Options are repurchased hereunder, such shares shall again be available under this Plan for reissuance as Options.  

6. Incentive Stock Options. Any of the Options to be granted hereunder may constitute Incentive Stock Options to the extent
expressly designated as such by the Committee or the Board. All Incentive Stock Options shall (a) have an exercise price per share of Common Stock of not less than 100% of the Fair Market Value of such share on the date of grant,
(b) not be exercisable more than ten years after the date of grant, (c) not be transferable other than by will or under the laws of descent and distribution and, during the lifetime of the Participant to whom such Incentive Stock Options
were granted, may be exercised only by such Participant (or his or her guardian or legal representative), and (d) be exercisable only during the Participant’s employment by the Company or a Subsidiary, provided, however, that
the Committee may, in its discretion, provide at the time that an Incentive Stock Option is granted that such Incentive Stock Option may be exercised for a period ending no later than either (x) the termination of this Plan in the event of the
Participant’s death while an employee of the Company or a Subsidiary or (y) the date which is three months after the Participant’s Termination Date for any other reason. The Committee’s discretion to extend the period during
which an Incentive Stock Option is exercisable shall only apply if and to the extent that (i) the Participant was entitled to exercise such 

  
 5 

 
Incentive Stock Option on the Participant’s Termination Date and (ii) such Incentive Stock Option would not have expired had the Participant continued to be employed by the Company or a
Subsidiary. To the extent that the aggregate Fair Market Value of shares with respect to which Incentive Stock Options are exercisable for the first time by any individual during any calendar year exceeds $100,000, such Options shall be treated as
Options which are not Incentive Stock Options. 
 7. Listing, Registration and Compliance with Laws and Regulations. Each Option
shall be subject to the requirement that if at any time the Committee shall determine, in its discretion, that the listing, registration or qualification of the shares subject to the Option upon any securities exchange or under any federal, state or
foreign securities or other law or regulation, or the consent or approval of any governmental regulatory body, is necessary or desirable as a condition to or in connection with the granting of such Option or the issue or purchase of shares
thereunder, no such Option may be exercised or paid in shares of Common Stock in whole or in part unless such listing, registration, qualification, consent or approval (a “Required Listing”) shall have been effected or obtained, and
the holder of each such Option will supply the Company with such certificates, representations and information as the Company shall request which are reasonably necessary or desirable in order for the Company to obtain such Required Listing, and
shall otherwise cooperate with the Company in obtaining such Required Listing. In the case of officers and other persons subject to Section 16(b) of the Securities Exchange Act of 1934, as amended, the Committee may at any time impose any
limitations upon the exercise of an Option which, in the Committee’s discretion, are necessary or desirable in order to comply with Section 16(b) and the rules and regulations thereunder. If the Company, as part of an offering of
securities or otherwise, finds it desirable because of federal, state or foreign regulatory requirements to reduce the period during which any Option may be exercised, the Committee may, in its discretion and without the consent of the holders of
any such Option, so reduce such period on not less than 15 days’ written notice to the holders thereof. 
 8. Adjustment for Change
in Common Stock. In the event of a reorganization, recapitalization, stock split, stock dividend, combination of shares, merger, consolidation or other change in Common Stock, the Committee shall make appropriate changes in the number and type
of shares authorized by this Plan, the number and type of shares covered by outstanding Options and the prices specified therein. 
 9.
Taxes. The Company shall be entitled, if necessary or desirable, to withhold (or secure payment from the Participant in lieu of withholding) the amount of any withholding or other tax due with respect to any amount payable and/or shares
issuable under this Plan, and the Company may defer any such payment or issuance unless and until indemnified to its satisfaction. 
 10.
Termination and Amendment. The Committee at any time may suspend or terminate this Plan and make such additions or amendments as it deems advisable under this Plan, except that it may not, without further approval by the Company’s
stockholders, (a) increase the maximum number of shares as to which Options may be granted under this Plan, except pursuant to Section 8 above, or (b) extend the term of this Plan; provided that, subject to
the other provisions hereof, the Committee may not change any of the terms of a written agreement with respect to an Option between the Company and the holder of such Option in a manner which would have a material adverse effect on the holder of
such Option without the approval of the holder of such Option. No Options shall be granted or shares of Common Stock issued hereunder after the tenth anniversary of the Effective Date; provided that, if the term of this Plan is otherwise
extended, no Incentive Stock Options shall be granted hereunder after the tenth anniversary of the original Effective Date.

 11. Participant Acknowledgments. In connection with the grant of any Option and/or
the issuance of any Common Stock pursuant to this Plan, each Participant acknowledges and agrees, that as a condition to any such grant or issuance: 

(a) The Company will have no duty or obligation to disclose to any Participant, and no Participant will have any right to be advised of, any
material information regarding the Company or its Subsidiaries at any time prior to, upon or in connection with the repurchase of any Option Shares upon the termination of such Participant’s employment with the Company or its Subsidiaries or as
otherwise provided under this Plan or any written agreement evidencing the grant of any Option or the issuance of any shares of Common Stock. 

(b) Neither the grant of any Option, the issuance of any Common Stock nor any provision contained in this Plan or in any written agreement
evidencing the grant of any Option or the issuance of any Common Stock shall entitle such Participant to remain in the employment or service of the Company or its Subsidiaries or affect the right of the Company to terminate any Participant’s
employment or service at any time for any or no reason. 
 (c) Such Participant will have consulted, or will have had an opportunity to
consult with, independent legal counsel regarding his or her rights and obligations under this Plan and any written agreement evidencing any grant of any Option, and he or she fully understands the terms and conditions contained herein and therein.

 (d) Prior to the purchase of any shares of Common Stock pursuant to this Plan or any written agreement evidencing the purchase of any
shares of Common Stock, such Participant will deliver to the Company an executed consent from such Participant’s spouse (if any) in the form of Exhibit 1 attached hereto. If, at any time subsequent to the date such Participant purchases
any shares of Common Stock and prior to the occurrence of a Termination Event, such Participant becomes legally married (whether in the first instance or to a different spouse), such Participant shall cause his or her spouse to execute and deliver
to the Company a consent in the form of Exhibit 1 attached hereto. Such Participant’s failure to deliver the Company an executed consent in the form of Exhibit 1 at any time when such Participant would otherwise be required to
deliver such consent shall constitute such Participant’s continuing representation and warranty that such Participant is not legally married as of such date. At the request of the Company, all Participants shall execute a joinder to any
stockholders agreement among the equityholders of the Company then in effect. 
 12. Repurchase Option. 

(a) Repurchase Option. If a Participant is no longer employed by the Company or any of its Subsidiaries for any or no reason (or in the
case of a Participant who was not an employee, if the Participant is no longer acting as a director or officer of, or consultant or advisor to, the Company or any of its Subsidiaries), the Option Shares (whether held by such Participant or one or
more transferees of such Participant, other than the Company or any Investor) will be subject to repurchase by the Investors and the Company (each of the aforementioned solely at their option) pursuant to the terms and conditions set forth in this
Section 12 (the “Repurchase Option”). 
 (b) Repurchase Price. Following a
Participant’s Termination Date, the Investors and the Company may elect to repurchase all or any portion of the Participant’s Option Shares at a price per share equal to (i) Original Cost, in the event of the Participant’s
termination for Cause, resignation without Good Reason, or engagement in a Competitive Activity prior to the repurchase date, or (ii) Fair Market Value (as of the date of repurchase), in the event of the Participant’s termination without
Cause or resignation for Good Reason, provided that if the Participant engages in a Competitive Activity following the Termination Date, the Participant shall pay to the Company the difference between the Fair Market Value (as of the date of
repurchase) and the Original Cost, if any. In the event any rights pursuant to the Repurchase Option may arise, the Company will promptly notify the Investors thereof. 

  
 7 

 (c) Repurchase Procedures. Subject to Section 12(b), each
Investor may elect to exercise the Repurchase Option to purchase up to its pro rata share (determined based upon the number of shares of Common Stock then held by each such Investor) by delivering written notice (the “Initial Repurchase
Notice”) to the holder or holders of the Option Shares, the Company and the other Investors no later than 180 days after the latest of (i) the Participant’s Termination Date,
(ii) the 181st day following the acquisition of the Option Shares subject to such repurchase, and (iii) the date upon which the Company and the Investors become aware that the
Participant engaged in a Competitive Activity. To the extent that any of the Investors do not elect to repurchase their full allotment of Option Shares no later than the fifth business day following delivery of the first Initial Repurchase Notice
delivered by any Investor (and, immediately following the completion of such fifth business day, the Company will notify in writing each of the Investors if any of the Investors have not elected to purchase their full allotment of Option Shares),
the other Investors shall be entitled to purchase all or any portion of the remaining Option Shares by providing notice (the “Supplemental Repurchase Notice”) to each of the parties receiving the Initial Repurchase Notice within ten
business days following the delivery of the first Initial Repurchase Notice delivered by any Investor; provided that if in the aggregate such Investors elect to purchase more than the remaining available Option Shares, such remaining available
Option Shares purchased by each Investor will be reduced on a pro rata basis based upon the number of shares of Common Stock then held by each electing Investor. To the extent that, after giving effect to the reoffer pursuant to the immediately
preceding sentence, any portion of the Option Shares are not being repurchased by the Investors, the Company may exercise the Repurchase Option for the remaining Option Shares by delivering written notice (a “Company Repurchase
Notice” and, together with the Initial Repurchase Notice and Supplemental Repurchase Notice, a “Repurchase Notice”) to the holder or holders of the applicable Option Shares within ten business days of the expiration of the
latest period during which the Investors were entitled to deliver Repurchase Notices. Each Repurchase Notice will set forth the number of Option Shares to be acquired from such holder(s), the aggregate consideration to be paid for such Option Shares
and the time and place for the closing of the transaction. If any Option Shares are held by any transferees of a Participant, the Investors and the Company, as the case may be, will purchase the shares elected to be purchased from all such holder(s)
of Option Shares, pro rata according to the number of Option Shares held by each such holder(s) at the time of delivery of such Repurchase Notice (determined as nearly as practicable to the nearest share). If Option Shares of different classes are
to be purchased pursuant to the Repurchase Option and such Option Shares are held by any transferees of a Participant, the number of shares of each class of Option Shares to be purchased will be allocated among all such holders, pro rata according
to the total number of Option Shares to be purchased from such Persons. 
 (d) Closing. The closing of the transactions contemplated
by this Section 12 will take place on the date designated in the applicable Repurchase Notice, which date will not be more than 90 days after the delivery of such notice. Each Investor will pay for the Option Shares to be
purchased by it by, at its option, wire transfer of immediately available funds or delivery of a check payable to the holder of such Option Shares. The Company will pay for the Option Shares to be purchased by it by first offsetting amounts
outstanding under any bona fide debts owing by such Participant to the Company or any of its Subsidiaries, now existing or hereinafter arising (irrespective as to whether such amounts are owing by the holder of such Option Shares), and will pay the
remainder of the purchase price by, at its option, (i) wire transfer of immediately available funds, (ii) delivery of a check payable to the holder of such Option Shares, (iii) a subordinated promissory note payable in three equal
annual installments commencing on the first anniversary of the closing of such purchase and bearing interest at a rate per annum equal to 5% or (iv) a combination of (i), (ii) and (iii), in the aggregate amount of the purchase price for such
shares. Notwithstanding anything to the contrary contained herein, all repurchases of Option Shares by the Company will be subject to applicable restrictions contained in the corporation law of the Company’s jurisdiction of incorporation and in
the Company’s and its Subsidiaries’ debt and equity financing agreements. If any such restrictions prohibit the repurchase of Option Shares hereunder which the Company is otherwise entitled to make, the Company may make such repurchases as
soon as it is 

  
 8 

 
permitted to do so under such restrictions. The Investors and/or the Company, as the case may be, will receive customary representations and warranties from each seller regarding the sale of the
Option Shares, including, but not limited to, representations that such seller has good and marketable title to the Option Shares to be transferred free and clear of all liens, claims and other encumbrances. 

(e) Termination of Repurchase Option. In the event of an IPO, the Repurchase Option under this Section 12
shall terminate, and the Option Shares shall no longer be subject to repurchase pursuant to this Section 12 by the Investors or the Company. 

13. Restrictions on Transfer. 

(a) Transfer of Option Shares. No Participant may sell, transfer, assign, pledge, encumber or otherwise dispose of (whether directly or
indirectly, whether with or without consideration and whether voluntarily or involuntarily or by operation of law) any interest (legal or beneficial) in any Option Shares (a “Transfer”) except Transfers pursuant to Sections
12, 13(b), 16 or 17 hereof (or as otherwise set forth in any written agreement with respect to the issuance of Options between the Company and such Participant), in each case pursuant to the terms and limitations set forth
therein. 
 (b) Certain Permitted Transfers. The restrictions contained in Section 13(a) will not apply
with respect to Transfers of Option Shares by a Participant (i) to its Affiliates, (ii) pursuant to Section 16, (iii) pursuant to Section 17, or (iv) pursuant to applicable laws of
descent or distribution or among a Participant’s Family Group; provided that the restrictions contained in this Plan will continue to apply to the Option Shares after any Transfer pursuant to clause (i) or (iv) above and each
transferee of such Option Shares shall agree in writing, prior to and as a condition precedent to the effectiveness of such Transfer, to be bound by the provisions of this Plan, without modification or condition, subject only to the consummation of
the Transfer. Upon the Transfer of Option Shares pursuant to clause (i) or (iv) of this Section 13(b), the transferring Participant will deliver a written notice to the Company and the Investors, which notice will
disclose in reasonable detail the identity of such transferee(s) and shall include an original counterpart of the agreement of such transferee(s) to be bound by this Plan. Notwithstanding the foregoing, no Participant shall avoid the provisions of
this Plan by making one or more transfers to one or more transferees permitted under clause (i) above and then disposing of all or any portion of such Participant’s interest in such transferee. “Family Group” means a
Participant’s spouse and descendants (whether by birth or adoption) and any trust solely for the benefit of such Participant and/or such Participant’s spouse and/or such Participant’s descendants (by birth or adoption), parents or
dependents, or any charitable trust the grantor of which is such Participant and/or a member of the Participant’s Family Group. Any transferee of Option Shares pursuant to a transfer in accordance with the provisions of this
Section 13(b) is herein referred to as a “Permitted Transferee.” 
 (c) Termination of
Restrictions. The rights and restrictions on the transfer of Option Shares set forth in this Section 13 will continue with respect to each Option Share until the earlier of (i) the consummation of an Approved Sale
(as defined below) and (ii) the consummation of an IPO. 
 14. Additional Restrictions on Transfer. 

 

	 	(a)	 The certificates representing the Option Shares will bear the following legend: 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“ACT”), AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN 

  
 9

AGREEMENTS SET FORTH IN THE ISSUER’S 2017 STOCK OPTION PLAN AND A WRITTEN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF SUCH SECURITIES, COPIES OF WHICH MAY BE OBTAINED BY THE HOLDER HEREOF AT THE ISSUER’S PRINCIPAL PLACE OF

 (b) No holder of Option Shares may sell, transfer or dispose of any Option Shares (except pursuant to an
effective registration statement under the Securities Act) without first, if requested by the Company, delivering to the Company an opinion of counsel reasonably acceptable in form and substance to the Company (which counsel shall be reasonably
acceptable to the Company) that registration under the Securities Act is not required in connection with such transfer. 
 (c) No holder of
Option Shares will effect any public sale or distribution (including sales pursuant to Rule 144 of the Securities Act) of any Option Shares or of any other equity securities of the Company, or any securities, options or rights convertible into or
exchangeable or exercisable for such securities, during the seven days prior to and the 180-day period beginning on the effective date of any underwritten public offering of the Company’s securities,
except as part of such underwritten public offering. The restrictions on transfer set forth in this Section 14(c) shall continue with respect to each Option Share and each other security, option or right described in the
preceding sentence until the date on which such security has been transferred pursuant to an offering registered under the Securities Act or to the public through a broker, dealer or market maker pursuant to the provisions of Rule 144 (other than
Rule 144(k)) adopted under the Securities Act. 
 15. Definition of Option Shares. For all purposes of this Plan, Option Shares will
continue to be Option Shares in the hands of any holder other than such Participant (except for the Company, the Investors or purchasers pursuant to an offering registered under the Securities Act or purchasers pursuant to a Rule 144 transaction
(other than a Rule 144(k) transaction occurring prior to the time of a closing of an IPO)), and each such other holder of Option Shares will succeed to all rights and obligations attributable to such Participant as a holder of Option Shares
hereunder and under any separate written agreement between the Company and such Participant. Option Shares will also include shares of the Company’s capital stock issued with respect to Option Shares by way of a share split, share dividend or
other recapitalization. 
 16. Sale of the Company. 

(a) If the holders of a majority of the Company Stock held by the Investors (the “Requisite Holders”) approve (i) a sale
of all or a majority of the Company’s assets determined on a consolidated basis or a sale of a majority of the Company’s outstanding capital stock (whether by merger, recapitalization, consolidation, reorganization, combination or
otherwise) to any Independent Third Party or group of Independent Third Parties or (ii) a Transfer of any shares of Company Stock in connection with a Strategic Transaction (collectively, an “Approved Sale”), each holder of
Option Shares shall vote for (to the extent entitled to vote) at a shareholders meeting or by written consent, and shall consent to and raise no objections against, the Approved Sale and the process by which such Approved Sale is arranged. If the
Approved Sale is structured as (x) a merger or consolidation, each holder of Option Shares shall waive all dissenters’ rights, appraisal rights and similar rights in connection with such merger or consolidation, (y) a sale of assets,
each holder of Option Shares shall vote in favor of the dissolution and 

  
 10 

 
liquidation of the Company following consummation of the Approved Sale if requested by such Requisite Holders or (z) a sale of Company Stock, each holder of Option Shares shall agree to sell
and surrender all of such holder’s Option Shares at the same price and on the same other terms and conditions, as applicable, as approved by such Requisite Holders. The Company and holders of Option Shares shall take all necessary or desirable
actions reasonably requested in good faith by such Requisite Holders in connection with the consummation of the Approved Sale, and execute all agreements, documents and instruments in connection therewith, as reasonably requested in good faith by
such Requisite Holders (including, without limitation, (A) with respect to the Company, providing potential purchasers with reasonable due diligence access to the books and records, personnel and facilities of the Company and its Subsidiaries
(subject to customary confidentiality provisions) in order to facilitate an Approved Sale, (B) with respect to holders of Option Shares who are also employees of the Company or any Subsidiary, entering into confidentiality, non-competition, non-solicitation and non-hire agreements requested by the proposed purchaser and (C) with respect to all holders
of Option Shares, entering into a sale contract, letters of transmittal and similar agreements and instruments as reasonably required in good faith by such Requisite Holders pursuant to which each holder shall: (1) severally (but not jointly)
make such indemnities regarding the Company and its Subsidiaries and their assets, liabilities and businesses (the “Company Reps”) as approved by such Requisite Holders and (2) solely on behalf of such holder, make such
representations, warranties, covenants and indemnities concerning such holder and the Option Shares to be sold by such holder as may be set forth in any agreement approved by such Requisite Holders (the “Holder Reps”);
provided that the allocable share of any holder of Option Shares for any amounts payable in connection with any claim by the purchaser for a breach of the Company Reps (any such amount payable, a “Company Loss”) shall be
determined in accordance with Section 16(c), and if any holder of Option Shares pays for more than such holder’s allocable share of a Company Loss (such overpayment, the “Excess Amount”), then each
other holder of Company Stock shall promptly contribute to such holder an amount equal to such other holder’s pro rata share of such Excess Amount as determined in accordance with Section 16(c)). Notwithstanding
anything to the contrary contained herein, no holder of Option Shares shall be liable for Company Losses in the aggregate (taken together with aggregate indemnification losses with respect to the Holder Reps) in an amount greater than such
holder’s pro rata share (based upon the total consideration received for the Company Stock in the Approved Sale) of the total consideration paid by the buyer in respect of the Approved Sale (including all amounts paid to repay indebtedness of
the Company and its Subsidiaries in connection with such Approved Sale). 
 (b) The obligation of each holder of Option Shares with respect
to an Approved Sale shall be subject to the satisfaction of the following conditions: (i) upon the consummation of the Approved Sale, each holder of Option Shares (in its capacity as such) shall have the right to receive with respect to each
applicable class thereof the same form and amount of consideration; (ii) if any holders of a class of Company Stock are given an option as to the form and amount of consideration to be received, each holder of such class of Option Shares shall
be given the same option (other than, in the case of clause (i) or this clause (ii), any consideration, option, right or benefit to be received by a holder on account of such individual’s employment relationship with the Company and its
Subsidiaries (e.g., a stay bonus, noncompetition agreement, right to reinvest or roll over equity, etc.)); and (iii) each holder of Options shall be given an opportunity to either (A) exercise such rights prior to the consummation of the
Approved Sale and participate in such sale as a holder of such class of Company Stock or (B) upon the consummation of the Approved Sale, receive in exchange for such rights consideration equal to the amount determined by multiplying
(1) the same amount of consideration per share of a class of Company Stock received by holders of such class of Company Stock in connection with the Approved Sale less the exercise price per share of such class of Option Shares of such rights
to acquire such class of Company Stock by (2) the number of shares of such class of Company Stock represented by such rights. 

  
 11 

 (c) In the event an Approved Sale occurs (whether pursuant to this
Section 16 or otherwise), each holder of Option Shares shall receive in exchange for such Option Shares held by such holder an amount (the “Sale Proceeds Amount”) equal to the amount that such holder would have
received in respect of such holder’s Option Shares if the aggregate consideration (after satisfaction or assumption of all debts and liabilities) from such Approved Sale had been distributed by the Company in accordance with the order of
priority as set forth in the Company’s Certificate of Incorporation (and, if less than all of the Company Stock is included in such transaction, then the allocation of such aggregate net consideration shall be determined as if the stock
included in such transaction was all of the Company Stock then outstanding, and for purposes of this Section 16(c), the terms of the Company’s Certificate of Incorporation shall be interpreted consistent with this
assumption). The allocable share of each holder of Option Shares of any Company Loss shall be an amount equal to the amount by which such holder’s Sale Proceeds Amount would have been reduced had the aggregate consideration from such Approved
Sale been distributed by the Company in accordance with the immediately foregoing sentence after deducting from such aggregate consideration the aggregate amount of such Company Loss. The Company shall pay all transaction costs associated with any
Approved Sale to the extent such costs are incurred for the benefit of all holders of Company Stock (as determined by the Board). To the extent such costs are not incurred by the Company prior to the distribution to the holders of Option Shares of
proceeds from any Approved Sale or by the acquiring company, such costs shall be borne by each holder of Option Shares according to such holder’s pro rata share (based upon the total consideration received for the Company Stock in the Approved
Sale) of the costs of any Approved Sale. Expenses incurred by any holder of Option Shares on its own behalf (and not simultaneously for the benefit of all other holders of Company Stock as approved by the Board) shall not be considered expenses of
the transaction and shall be the sole responsibility of such holder. Each holder of Option Shares shall take all necessary or desirable actions in connection with the distribution of the aggregate consideration from such Approved Sale, merger
or Transfer as reasonably requested in good faith by the Requisite Holders. 
 (d) If the Company or the holders of Option Shares enter into
any negotiation or transaction for which Rule 506 (or any similar rule then in effect) promulgated by the Securities and Exchange Commission may be available with respect to such negotiation or transaction (including, without limitation, a merger,
consolidation or other reorganization), the holders of Option Shares shall at the request of the Company, appoint a “purchaser representative” (as such term is defined in Rule 501 (or any similar rule then in effect) promulgated by the
Securities and Exchange Commission) reasonably acceptable to the Company. If any holder of Option Shares appoints a purchaser representative designated by the Company, the Company shall pay the fees of such purchaser representative. However, if any
holder of Option Shares declines to appoint the purchaser representative designated by the Company, such holder shall appoint another purchaser representative (reasonably acceptable to the Company), and such holder shall be responsible for the fees
of the purchaser representative so appointed. 
 (e) If any holder of Option Shares does not, in connection with an Approved Sale, execute
and/or deliver all transfer and other documents required to be executed and/or delivered, and take all other actions required to be taken, by such holder pursuant to this Section 16 in respect of all of the Option Shares
held by such holder, such defaulting holder shall be deemed to have irrevocably appointed each and any member of the Board (or any officer appointed by the Board), acting individually, to be such holder’s agent and attorney-in-fact to execute and/or deliver all necessary transfer and other documents, and take all other necessary actions, on such holder’s behalf in connection with
such Approved Sale. 
 (f) The provisions of Sections 16(b), (c) and (d) hereof will terminate on the first to
occur of (i) the consummation of an IPO and (ii) the consummation of an Approved Sale (except as such provisions relate to any such Approved Sale). 

  
 12 

 17. Public Offering. If the Board and the Requisite Holders approve an IPO, the
holders of Option Shares will take all reasonably necessary or desirable actions in connection with the consummation of the IPO. If the IPO is an underwritten offering and the managing underwriters advise the Company in writing that in their opinion
the capital stock structure will adversely affect the marketability of the offering, each holder of Option Shares will consent to and vote for a recapitalization, reorganization and/or exchange of the shares of Company’s capital stock into
securities that the managing underwriters, the Board and the holders of a majority of the Common Stock then held by the Investors find acceptable and will take all necessary or desirable actions in connection with the consummation of the
recapitalization, reorganization and/or exchange; provided that the resulting securities reflect and are consistent with the rights and preferences set forth in the Company’s Certificate of Incorporation as in effect immediately prior to the
IPO. The provisions of this Section 17 and all references to the defined term “IPO” in this Plan will apply, mutatis mutandis, to (a) any initial public offering and sale of any common stock of any
Subsidiary of the Company and the liquidation of the Company into any such Subsidiary in connection therewith and (b) any Solvent Reorganization approved by the Board. In connection with any such public offering and sale of any common stock of
any Subsidiary of the Company, the Company shall liquidate into such Subsidiary or take other appropriate action to distribute the securities of such Subsidiary. 

18. Transfers in Violation of Plan. Any transfer or attempted transfer of any Option Shares in violation of any provision of this Plan
shall be void, and the Company shall not record such transfer on its books or treat any purported transferee of such Option Shares as the owner of such shares for any purpose. 

19. Severability. Whenever possible, each provision of this Plan will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Plan is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other
provision or any other jurisdiction, but this Plan will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. 

20. Remedies. Each of the Company, any Participant and the Investors will be entitled to enforce its rights under this Plan
specifically, to recover damages and costs (including reasonable attorneys’ fees) caused by any breach of any provision of this Plan and to exercise all other rights existing in its favor. Each Participant and the Company acknowledges and
agrees that money damages may not be an adequate remedy for any breach of the provisions of this Plan and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction (without posting any bond or deposit)
for specific performance and/or other injunctive relief in order to enforce or prevent any violations of the provisions of this Plan. 
 21.
Business Days. If any time period for giving notice or taking action hereunder expires on a day which is a Saturday, Sunday or holiday in the state in which the Company’s chief executive office is located, the time period shall be
automatically extended to the business day immediately following such Saturday, Sunday or holiday. 
 22. Governing Law. All issues
concerning this Plan will be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision of rule (whether of the State of Delaware or any other jurisdiction)
that would cause the application of the law of any jurisdiction other than the State of Delaware. Each of the Company and each Participant submits to the co-exclusive jurisdiction of the United States District
Court and any Delaware state court sitting in Wilmington, Delaware over any lawsuit under this Plan and waives any objection based on venue or forum non conveniens with respect to any action instituted therein. Each of

  
 13 

 
the Company and each Participant waives the necessity for personal service of any and all process upon it and consents that all such service of process may be made by registered or certified mail
(return receipt requested), in each case directed to such party in accordance with the notice requirements set forth in this Plan, and service so made will be deemed to be completed on the date of actual receipt. Each of the Company and each
Participant consents to service of process as aforesaid. Nothing in this Plan will prohibit personal service in lieu of the service by mail contemplated herein. 

23. Notices. Any notice required or permitted under this Plan or any agreement executed and delivered in connection with this Plan
shall be in writing and shall be either delivered by facsimile (which shall be effective upon receipt of confirmation of successful transmission), personally delivered, or mailed by first class mail, return receipt requested, to any Participant at
the address indicated in the Company’s records for such Person, and to the Company at the facsimile number and address below indicated:

DIRECTOR NOMINATION AGREEMENT 

THIS DIRECTOR NOMINATION AGREEMENT (this “Agreement”) is made and entered into as
of                    , 2020, by and among Datto Holding Corp., a Delaware corporation (the “Company”), Vista Foundation Fund II,
L.P., Vista Foundation Fund II-A, L.P., VFF II FAF, L.P., Vista Foundation Fund II Executive, L.P., Vista Foundation Associates II, L.P., Merritt VI Aggregator, LLC (collectively referred to herein as the
“Vista Funds”), VEP Group, LLC (“VEP Group” and, together with the Vista Funds and their Affiliates (as defined herein), “Vista”) and each of the Persons listed on Schedule I hereto
(collectively, the “McChord Stockholders”). This Agreement shall become effective (the “Effective Date”) upon the closing of the Company’s initial public offering (the “IPO”) of shares of its
common stock, par value $0.001 per share (the “Common Stock”). 
 WHEREAS, as of the date hereof, the Vista Funds
collectively own all of the outstanding equity interests of the Company (apart from interests held by the McChord Stockholders and certain current and former directors, officers and employees of the Company) and whereas VEP Group is the indirect
beneficial owner of the majority of such equity interests; 
 WHEREAS, Vista is contemplating causing the Company to effect the IPO; 

WHEREAS, the McChord Stockholders currently have the authority to appoint one director of the Company and Vista currently has the authority to
appoint all remaining directors of the Company; 
 WHEREAS, in consideration of Vista agreeing to undertake the IPO, the Company has agreed
to permit Vista and the McChord Stockholders to designate persons for nomination for election to the board of directors of the Company (the “Board”) following the Effective Date on the terms and conditions set forth herein; 

NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, each of the parties to this Agreement agrees as follows: 
 1.    Board
Nomination Rights. 
 (a)    From the Effective Date, VEP Group shall have the right, but not the obligation, to
nominate to the Board a number of designees (such persons, the “Vista Nominees”) equal to at least: (x) (i) 100% of the Total Number of Directors (as defined below), so long as Vista Beneficially Owns shares of Common Stock
representing at least 40% of the Original Amount of VEP Group, (ii) 40% of the Total Number of Directors, in the event that Vista Beneficially Owns shares of Common Stock representing at least 30% but less than 40% of the Original Amount of VEP
Group, (iii) 30% of the Total Number of Directors, in the event that Vista Beneficially Owns shares of Common Stock representing at least 20% but less than 30% of the Original Amount of VEP Group, (iv) 20% of the Total Number of Directors, in the
event that Vista Beneficially Owns shares of Common Stock representing at least 10% but less than 20% of the Original Amount of VEP Group and (v) 1 Director (as defined below), in the event that Vista Beneficially Owns shares

 
of Common Stock representing at least 5% of the Original Amount of VEP Group, minus (y) the number of designees, if any, the McChord Stockholders are then entitled to nominate
pursuant to Section 1(b). For purposes of calculating the number of directors that VEP Group is entitled to designate pursuant to the immediately preceding sentence, any fractional amounts shall automatically be rounded up
to the nearest whole number (e.g., 11⁄4 Directors shall equate to 2 Directors) and any such calculations shall be made after taking into account any increase in the
Total Number of Directors. 
 (b)    From the Effective Date, the McChord Stockholders shall have the right, but not the
obligation, to nominate to the Board one designee (the “McChord Nominee” and, together with the Vista Nominees, the “Nominees”), until such time as the McChord Stockholders cease to beneficially own at least 5% of
the outstanding Common Stock; provided, that any designee other than Austin McChord shall be subject to the prior written approval of VEP Group. 

(c)    In the event that VEP Group has nominated less than the total number of designees, VEP Group shall be entitled to
nominate pursuant to Section 1(a), Vista shall have the right, at any time, to nominate such additional designees to which it is entitled, in which case, the Company and the Directors shall take all necessary corporation
action, to the fullest extent permitted by applicable law (including with respect to fiduciary duties under Delaware law), to (x) enable VEP Group to nominate and effect the election or appointment of such additional individuals, whether by
increasing the size of the Board, or otherwise and (y) to designate such additional individuals nominated by VEP Group to fill such newly created vacancies or to fill any other existing vacancies. 

(d)    In addition to the nomination rights set forth in Section 1(a) above, from the Effective
Date, for so long as Vista Beneficially Owns shares of Common Stock representing at least 5% of the Original Amount of VEP Group, VEP Group shall have the right, but not the obligation, to designate a person (a “Non-Voting Observer”) to attend meetings of the Board (including any meetings of any committees thereof) in a non-voting observer capacity. Any such Non-Voting Observer shall be permitted to attend all meetings of the Board. VEP Group shall have the right to remove and replace its Non-Voting Observer at any time and from
time to time. The Company shall furnish to any Non-Voting Observer (i) notices of Board meetings no later than, and using the same form of communication as, notice of Board meetings are furnished to
directors and (ii) copies of any materials prepared for meetings of the Board that are furnished to the directors no later than the time such materials are furnished to the directors; provided that failure to deliver notice, or materials, to
such Non-Voting Observer in connection with such Non-Voting Observer’s right to attend and/or review materials with respect to, any meeting of the Board shall not,
by itself, impair the validity of any action taken by such Board at such meeting. Such Non-Voting Observer shall be required to execute or otherwise become subject to any codes of conduct or confidentiality
agreements of the Company generally applicable to directors of the Company or as the Company reasonably requests. 

(e)    The Company shall pay all reasonable
out-of-pocket expenses incurred by the Nominees and the Non-Voting Observer in connection with the performance of his or her
duties as a director or a Non-Voting Observer and in connection with his or her attendance at any meeting of the Board. 

  
 2 

 (f)    “Beneficially Own” shall mean that a specified
person has or shares the right, directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, to vote shares of capital stock of the Company. “Affiliate” of any person shall mean any other
person controlled by, controlling or under common control with such person; where “control” (including, with its correlative meanings, “controlling,” “controlled by” and “under common
control with”) means possession, directly or indirectly, of power to direct or cause the direction of management or policies (whether through ownership of securities, by contract or otherwise). 

(g)    “Director” means any member of the Board. 

(h)    “Original Amount of VEP Group” means the aggregate number of shares of Common Stock held, directly
or indirectly, by VEP Group on the date hereof, as such number may be adjusted from time to time for any reorganization, recapitalization, stock dividend, stock split, reverse stock split or other similar changes in the Company’s
capitalization. 
 (i)    “Person” means any natural person, sole proprietorship, partnership, trust,
unincorporated association, corporation, limited liability company, entity or governmental entity. 

(j)    “Total Number of Directors” means the total number of Directors comprising the Board. 

(k)    No reduction in the number of shares of Common Stock that Vista Beneficially Owns shall shorten the term of any
incumbent director who is serving as a Vista Nominee. At such time as the McChord Stockholders cease to beneficially own at least 5% of the Common Stock then outstanding, the McChord Nominee shall promptly furnish his or her resignation to the
Board, which the Board may accept or reject in its sole discretion. At the Effective Date, the Board shall be comprised of                members and the initial Vista
Nominees shall be                and the initial McChord Nominee shall be Austin McChord. 

(l)    In the event that any Nominee shall cease to serve for any reason, VEP Group shall be entitled to designate such
person’s successor in accordance with this Agreement (regardless of Vista’s beneficial ownership in the Company at the time of such vacancy) and the Board shall promptly fill the vacancy with such successor nominee; it being understood
that any such designee shall serve the remainder of the term of the director whom such designee replaces. 
 (m)    If a
Vista Nominee or McChord Nominee is not appointed or elected to the Board because of such person’s death, disability, disqualification, withdrawal as a nominee or for other reason is unavailable or unable to serve on the Board, VEP Group or the
McChord Stockholders, as applicable, shall be entitled to designate promptly another nominee and the director position for which the original Nominee was nominated shall not be filled pending such designation. 

(n)    So long as VEP Group has the right to nominate Nominees under Section 1(a) or any such
Nominee is serving on the Board, the Company shall use its reasonable best efforts to maintain in effect at all times directors and officers indemnity insurance coverage reasonably satisfactory to Vista, and the Company’s Amended and Restated
Certificate of Incorporation and 

  
 3 

 
Amended and Restated Bylaws (each as may be further amended, supplemented or waived in accordance with its terms) shall at all times provide for indemnification, exculpation and advancement of
expenses to the fullest extent permitted under applicable law. 
 (o)    If the size of the Board is expanded, VEP Group
shall be entitled to nominate a number of Nominees to fill the newly created vacancies such that the total number of Nominees serving on the Board following such expansion will be equal to that number of Nominees that VEP Group would be entitled to
nominate in accordance with Section 1(a) if such expansion occurred immediately prior to any meeting of the stockholders of the Company called with respect to the election of members of the Board, and the Board shall
appoint such Nominees to the Board. 
 (p)    At such time as the Company ceases to be a “controlled company”
and is required by applicable law or the New York Stock Exchange (the “Exchange”) listing standards to have a majority of the Board comprised of “independent directors” (subject in each case to any applicable phase-in periods), Vista’s Nominees shall include a number of persons that qualify as “independent directors” under applicable law and the Exchange listing standards such that, together with any other
“independent directors” then serving on the Board that are not Nominees, the Board is comprised of a majority of “independent directors.” 

(q)    At any time that VEP Group or the McChord Stockholders shall have any nomination rights under
Section 1, the Company shall not take any action, including making or recommending any amendment to the Certificate of Incorporation or the Company’s bylaws that could reasonably be expected to adversely affect VEP
Group’s or the McChord Stockholders’ rights, respectively, under this Agreement, in each case without the prior written consent of VEP Group or the McChord Stockholders, respectively. 

2.    Company Obligations. The Company agrees to use its reasonable best efforts to ensure that prior to the date
that Vista and its Affiliates cease to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, (i) each Nominee is included in the Board’s slate of nominees to the
stockholders (the “Board’s Slate”) for each election of directors; and (ii) each Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of
the stockholders of the Company called with respect to the election of members of the Board (each, a “Director Election Proxy Statement”), and at every adjournment or postponement thereof, and on every action or approval by written
consent of the stockholders of the Company or the Board with respect to the election of members of the Board. VEP Group will promptly provide reporting to the Company after Vista ceases to Beneficially Own shares of Common Stock representing at
least 5% of the total voting power of the then outstanding Common Stock, such that Company is informed of when this obligation terminates. The calculation of the number of Nominees that VEP Group and the McChord Stockholders are entitled to nominate
to the Board’s Slate for any election of directors shall be based on the percentage of the total voting power of the then outstanding Common Stock then Beneficially Owned by Vista (“Vista Voting Control”) or the McChord
Stockholders, as applicable, immediately prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities
and Exchange Commission). Unless VEP Group notifies the Company otherwise prior to the mailing to shareholders of the Director

Election Proxy Statement relating to an election of directors, the Nominees for such election shall be presumed to be the same Nominees currently serving on the Board, and no further action shall
be required of VEP Group for the Board to include such Nominees on the Board’s Slate; provided, that, in the event VEP Group is no longer entitled to nominate the full number of Nominees then serving on the Board, VEP Group shall provide
advance written notice to the Company, of which currently servicing Nominee(s) shall be excluded from the Board Slate, and of any other changes to the list of Nominees. If VEP Group fails to provide such notice prior to the mailing to shareholders
of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission), a majority of the independent directors then
serving on the Board shall determine which of the Nominees of VEP Group then serving on the Board will be included in the Board’s Slate. Furthermore, the Company agrees for so long as the Company qualifies as a “controlled company”
under the rules of the Exchange the Company will elect to be a “controlled company” for purposes of the Exchange and will disclose in its annual meeting proxy statement that it is a “controlled company” and the basis for that
determination. The Company and Vista acknowledge and agree that, as of the Effective Date, the Company is a “controlled company.” 

3.    Committees. From and after the Effective Date hereof until such time as Vista and its Affiliates cease to
Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, Vista shall have the right to designate a number of members of each committee of the Board equal to the nearest whole
number greater than the product obtained by multiplying (a) the percentage of the total voting power of the then outstanding Common Stock then Beneficially Owned by Vista and (b) the number of positions, including any vacancies, on the
applicable committee, provided that any such designee shall be a director and shall be eligible to serve on the applicable committee under applicable law or listing standards of the Exchange, including any applicable independence requirements
(subject in each case to any applicable exceptions, including those for newly public companies and for “controlled companies,” and any applicable phase-in periods). Any additional members shall be
determined by the Board. Nominees designated to serve on a Board committee shall have the right to remain on such committee until the next election of directors, regardless of the level of Vista Voting Control following such designation. Unless VEP
Group notifies the Company otherwise prior to the time the Board takes action to change the composition of a Board committee, and to the extent Vista has the requisite Vista Voting Control for VEP Group to nominate a Board committee member at the
time the Board takes action to change the composition of any such Board committee, any Nominee currently designated by VEP Group to serve on a committee shall be presumed to be re-designated for such
committee. 
 4.    Amendment and Waiver. Any provision of this Agreement may be amended or waived if, but only
if, such amendment or waiver is in writing and is signed, in the case of an amendment, by the Company, Vista and the McChord stockholders, or in the case of a waiver, by the party against whom the waiver is to be effective; provided that the consent
of the McChord Stockholders shall not be required for an amendment or waiver at any time after the McChord Stockholders cease to beneficially own at least 5% of the Company’s outstanding common stock. No failure or delay by any party in
exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights
and remedies 

  
 5 

 
herein provided shall be cumulative and not exclusive of any rights or remedies provided by law. Neither VEP Group nor the McChord Stockholders shall be obligated to nominate all (or any) of the
Nominees each is entitled to nominate pursuant to this Agreement for any election of directors but the failure to do so shall not constitute a waiver of such party’s rights hereunder with respect to future elections; provided,
however, that in the event VEP Group or the McChord Stockholders fail to nominate all (or any) of the Nominees such parties are entitled to nominate pursuant to this Agreement prior to the mailing to shareholders of the Director Election
Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission), the Compensation and Nominating Committee of the Board shall be entitled to
nominate individuals in lieu of such Nominees for inclusion in the Board’s Slate and the applicable Director Election Proxy Statement with respect to the election for which such failure occurred and VEP Group or the McChord Stockholders, as
applicable, shall be deemed to have waived such parties’ rights hereunder with respect to such election. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law. 

5.     Benefit of Parties. This Agreement shall be binding upon and shall inure to the benefit of the parties
hereto and their respective permitted successors and assigns. Notwithstanding the foregoing, neither the Company nor the McChord Stockholders may assign any of their rights or obligations hereunder without the prior written consent of Vista. Except
as otherwise expressly provided in Section 6, nothing herein contained shall confer or is intended to confer on any third party or entity that is not a party to this Agreement any rights under this Agreement. 

6.    Assignment. Upon written notice to the Company, VEP Group may assign to any of the Vista Funds or any
Affiliate of VEP Group (other than a portfolio company) all of its rights hereunder and, following such assignment, such assignee shall be deemed to be “VEP Group” for all purposes hereunder. 

7.    Indemnification. 

(a)    The Company shall defend, indemnify and hold harmless Vista and the McChord Stockholders, their respective
Affiliates, partners, employees, agents, directors, managers, officers and controlling Persons (collectively, the “Indemnified Parties”) from and against any and all actions, causes of action, suits, claims, liabilities, losses, damages,
costs, expenses, or obligations of any kind or nature (whether accrued or fixed, absolute or contingent) in connection therewith (including reasonable attorneys’ fees and expenses) incurred by the Indemnified Parties before or after the date of
this Agreement (each, an “Action”) arising directly or indirectly out of, or in any way relating to, (i) any Vista Entity’s, McChord Stockholders’ or their respective Affiliates’ Beneficial Ownership of Common Stock or
other equity securities of the Company or control or ability to influence the Company or any of its subsidiaries (other than any such Actions (x) to the extent such Actions arise out of any breach of this Agreement by an Indemnified Party or
its Affiliates or the breach of any fiduciary or other duty or obligation of such Indemnified Party to its direct or indirect equity holders, creditors or Affiliates or (y) to the extent such Actions are directly caused by such Person’s
willful misconduct), (ii) the business, operations, properties, assets or other rights or liabilities of the Company or any of its subsidiaries or (iii) any services provided prior, on or after the date of this Agreement by any Vista Entity,
McChord Stockholder 

  
 6 

 
or their respective Affiliates to the Company or any of its subsidiaries. The Company shall defend at its own cost and expense in respect of any Action which may be brought against the Company
and/or its Affiliates and the Indemnified Parties. The Company shall defend at its own cost and expense any and all Actions which may be brought in which the Indemnified Parties may be impleaded with others upon any Action by the Indemnified
Parties, except that if such damage shall be proven to be the direct result of gross negligence, bad faith or willful misconduct by any of the Indemnified Parties, then such Indemnified Party shall reimburse the Company for the costs of defense and
other costs incurred by the Company in proportion to such Indemnified Party’s culpability as proven. In the event of the assertion against any Indemnified Party of any Action or the commencement of any Action, the Company shall be entitled to
participate in such Action and in the investigation of such Action and, after written notice from the Company to such Indemnified Party, to assume the investigation or defense of such Action with counsel of the Company’s choice at the
Company’s expense; provided, however, that such counsel shall be reasonably satisfactory to the Indemnified Party. Notwithstanding anything to the contrary contained herein, the Company may retain one firm of counsel to represent all
Indemnified Parties in such Action; provided, however, that the Indemnified Party shall have the right to employ a single firm of separate counsel (and any necessary local counsel) and to participate in the defense or investigation of such Action
and the Company shall bear the expense of such separate counsel (and local counsel, if applicable), if (x) in the opinion of counsel to the Indemnified Party use of counsel of the Company’s choice could reasonably be expected to give rise
to a conflict of interest, (y) the Company shall not have employed counsel satisfactory to the Indemnified Party to represent the Indemnified Party within a reasonable time after notice of the assertion of any such Action or (z) the
Company shall authorize the Indemnified Party to employ separate counsel at the Company’s expense. The Company further agrees that with respect to any Indemnified Party who is employed, retained or otherwise associated with, or appointed or
nominated by, Vista, the McChord Stockholders or any of their respective Affiliates and who acts or serves as a director, officer, manager, fiduciary, employee, consultant, advisor or agent of, for or to the Company or any of its subsidiaries, that
the Company or such subsidiaries, as applicable, shall be primarily liable for all indemnification, reimbursements, advancements or similar payments (the “Indemnity Obligations”) afforded to such Indemnified Party acting in such capacity
or capacities on behalf or at the request of the Company, whether the Indemnity Obligations are created by law, organizational or constituent documents, contract (including this Agreement) or otherwise. The Company hereby agrees that in no event
shall the Company or any of its subsidiaries have any right or claim against any Vista Entity or McChord Stockholder for contribution or have rights of subrogation against any Vista Entity or McChord Stockholder through an Indemnified Party for any
payment made by the Company or any of its subsidiaries with respect to any Indemnity Obligation. In addition, the Company hereby agrees that in the event that any Vista Entity or McChord Stockholder pay or advance an Indemnified Party any expenses
with respect to an Indemnity Obligation, the Company will, or will cause its subsidiaries to, as applicable, promptly reimburse any such Vista Entity or McChord Stockholder, respectively, for such payment or advance upon request; subject to the
receipt by the Company of a written undertaking executed by the Indemnified Party and the Vista Entity or McChord Stockholder, as applicable, that makes such payment or advance to repay any such amounts if it shall ultimately be determined by a
court of competent jurisdiction that such Indemnified Party was not entitled to be indemnified by the Company. The foregoing right to indemnity shall be in addition to any rights that any Indemnified Party may have at common law or otherwise and
shall remain in full force and effect following the completion or any termination 

  
 7 

 
of the engagement. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold it harmless as and to the extent contemplated by this
Section 7, then the Company shall contribute to the amount paid or payable by the Indemnified Party as a result of such Action in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and
the Indemnified Party, as the case may be, on the other hand, as well as any other relevant equitable considerations. 

(b)    The Company hereby acknowledges that the certain of the Indemnified Parties have certain rights to indemnification,
advancement of expenses and/or insurance provided by investment funds managed by Vista and certain of its Affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees with respect to any indemnification, hold harmless
obligation, expense advancement or reimbursement provision or any other similar obligation whether pursuant to or with respect to this Agreement, the organizational documents of the Company or any of its subsidiaries or any other agreement, as
applicable, (i) that the Company and its subsidiaries are the indemnitor of first resort (i.e., their obligations to the Indemnified Parties are primary and any obligation of the Fund Indemnitors to advance expenses or to provide
indemnification for claims, expenses or obligations arising out of the same or similar facts and circumstances suffered by any Indemnified Party are secondary), (ii) that the Company shall be required to advance the full amount of expenses incurred
by any Indemnified Party and shall be liable for the full amount of all expenses, liabilities, obligations, judgments, penalties, fines, and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement,
the organizational documents of the Company or any of its subsidiaries or any other agreement, as applicable, without regard to any rights any Indemnified Party may have against the Fund Indemnitors, and (iii) that the Company, on behalf of
itself and each of its subsidiaries, irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all Actions against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The
Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of any Indemnified Party with respect to any Action for which any Indemnified Party has sought indemnification from the Company shall affect the foregoing and
the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of any Indemnified Party against the Company. The Company agrees that the Fund Indemnitors are
express third-party beneficiaries of the terms of this Section 7(b). 
 8.    Headings. Headings are for
ease of reference only and shall not form a part of this Agreement. 
 9.    Governing Law. This Agreement shall
be construed in accordance with and governed by the law of the State of Delaware without giving effect to the principles of conflicts of laws thereof. 

10.    Jurisdiction. Any suit, action or proceeding seeking to enforce any provision of, or based on any matter
arising out of or in connection with, this Agreement may be brought against any of the parties in any federal court located in the State of Delaware or any Delaware state court, and each of the parties hereby consents to the exclusive jurisdiction
of such court (and of the appropriate appellate courts) in any such suit, action or proceeding and waives any objection to 

  
 8 

 
venue laid therein. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting
the foregoing, each of the parties agrees that service of process upon such party at the address referred to in Section 17, together with written notice of such service to such party, shall be deemed effective service of
process upon such party. 
 11.    WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY

subject matter hereof and supersedes all prior agreements, understandings and negotiations, both written and oral among the parties with respect to the subject matter hereof. 

13.    Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall
be deemed an original. This Agreement shall become effective when each party shall have received a counterpart hereof signed by each of the other parties. An executed copy or counterpart hereof delivered by facsimile shall be deemed an original

 14.    Severability. If any provision of this Agreement or the application thereof to any person

permitted by law. 
 15.    Further Assurances. Each of the parties hereto shall execute and deliver such further
instruments and do such further acts and things as may be required to carry out the intent and purpose of this Agreement.
