 Exhibit 10.43 

ALLEGRO MICROSYSTEMS, INC. 

INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (the “Agreement”) is made and entered into as of ______________, 2020 between Allegro
MicroSystems, Inc., a Delaware corporation (the “Company”), and [Name] (“Indemnitee”). 

WITNESSETH THAT: 
 WHEREAS,
highly competent persons have become more reluctant to serve corporations as directors, officers or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of
claims and actions against them arising out of their service to and activities on behalf of the corporation; 
 WHEREAS, the Board of
Directors of the Company (the “Board”) has determined that, in order to attract and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect
persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such insurance has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company
believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or
business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself. The Bylaws
of the Company require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (“DGCL”). The Bylaws and
the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the Board, officers and other persons with respect to
indemnification; 
 WHEREAS, the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting
and retaining such persons; 
 WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is
detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on
behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

WHEREAS, this Agreement is a supplement to and in furtherance of the Bylaws of the Company and any resolutions adopted pursuant thereto, and
shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; [and] 

 WHEREAS, Indemnitee does not regard the protection available under the Company’s Bylaws
and insurance as adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to
serve and to take on additional service for or on behalf of the Company on the condition that he be so indemnified[; and] 
 [WHEREAS,
Indemnitee has certain rights to indemnification and/or insurance provided by [NAME] which Indemnitee and [NAME] intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s
acknowledgement and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve on the Board]. 
 NOW,
THEREFORE, in consideration of Indemnitee’s agreement to serve as an officer or director from and after the date hereof, the parties hereto agree as follows: 

1. Indemnity of Indemnitee. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law,
as such may be amended from time to time. In furtherance of the foregoing indemnification, and without limiting the generality thereof: 

(a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification
provided in this Section l(a) if, by reason of the Indemnitee’s Corporate Status (as hereinafter defined), the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (as hereinafter defined) other than a
Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as hereinafter defined), judgments, penalties, fines and amounts paid in settlement actually
and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in connection with such Proceeding or any claim, issue or matter therein, if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be
in or not opposed to the best interests of the Company, and with respect to any criminal Proceeding, had no reasonable cause to believe the Indemnitee’s conduct was unlawful. 

(b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this
Section 1(b) if, by reason of the Indemnitee’s Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to this
Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in connection with such Proceeding if the Indemnitee acted in good
faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, no indemnification against such Expenses shall be made in respect of any claim, issue or matter in such
Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that the Court of Chancery of the State of Delaware or the court in which such Proceeding was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper. 

  
 2 

 (c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful.
Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of the Indemnitee’s Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, he shall be indemnified to the
maximum extent permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by the Indemnitee or on the Indemnitee’s behalf in connection therewith. If Indemnitee is not wholly successful in
such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by the
Indemnitee or on the Indemnitee’s behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal,
with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 
 2. Additional Indemnity. In
addition to, and without regard to any limitations on, the indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee to the fullest extent
permitted by applicable law (including a Proceeding by or in the right of the Company). 
 3. Contribution. To the fullest extent
permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee,
whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and
reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding and/or
(ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 

4. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is,
by reason of the Indemnitee’s Corporate Status, a witness, or is made (or asked) to respond to discovery requests, in any Proceeding to which Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably
incurred by the Indemnitee or on the Indemnitee’s behalf in connection therewith. 
 5. Advancement of Expenses. Notwithstanding
any other provision of this Agreement, the Company shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after the receipt by
the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses
incurred by Indemnitee. The Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement, which shall constitute an undertaking by Indemnitee to repay any Expenses advanced if it shall ultimately be
determined that Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free.

 6. Procedures and Presumptions for Determination of Entitlement to Indemnification.
It is the intent of this Agreement to secure for Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly, the parties agree that the following procedures and
presumptions shall apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement: 
 (a)
To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to
determine whether and to what extent Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested
indemnification. Notwithstanding the foregoing, any failure of Indemnitee to provide such a request to the Company, or to provide such a request in a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee
unless, and to the extent that, such failure actually and materially prejudices the interests of the Company. 
 (b) Upon written request by
Indemnitee for indemnification pursuant to the first sentence of Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four
methods, which shall be at the election of the Board: (1) by a majority vote of the disinterested directors, even though less than a quorum, (2) by a committee of disinterested directors designated by a majority vote of the disinterested
directors, even though less than a quorum, (3) if there are no disinterested directors or if the disinterested directors so direct, by independent legal counsel in a written opinion to the Board, a copy of which shall be delivered to the
Indemnitee, or (4) if so directed by the Board, by the stockholders of the Company. For purposes hereof, disinterested directors are those members of the Board who are not parties to the action, suit or proceeding in respect of which
indemnification is sought by Indemnitee. 
 (c) If the determination of entitlement to indemnification is to be made by Independent Counsel
pursuant to Section 6(b) hereof, the Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board. Indemnitee may, within ten
(10) days after such written notice of selection shall have been given, deliver to the Company a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so
selected does not meet the requirements of “Independent Counsel” as defined in Section 13 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a
proper and timely objection, the person so selected shall act as Independent Counsel. If a written objection is made and substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is
withdrawn or a court has determined that such objection is without merit. If, within twenty (20) days after the conclusion of the Proceeding giving rise to the request for indemnification, no Independent Counsel shall have been selected and not
objected to, either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware for resolution of any objection which shall have been made by the Indemnitee to the Company’s

  
 4 

 
selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person with
respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 6(b) hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel
incurred by such Independent Counsel in connection with acting pursuant to Section 6(b) hereof, and the Company shall pay all reasonable fees and expenses incident to the procedures of this
Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed. 
 (d) In
making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome
this presumption shall have the burden of proof and the burden of persuasion. Neither the failure of the Company (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action pursuant
to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or independent legal counsel) that Indemnitee
has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(e) Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the
Enterprise (as hereinafter defined), including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or
records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. In addition, the knowledge and/or actions, or failure to act, of any
director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not the foregoing provisions of this
Section 6(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company. Anyone
seeking to overcome this presumption shall have the burden of proof and the burden of persuasion. 
 (f) If the person, persons or entity
empowered or selected under Section 6 to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after the conclusion of the Proceeding giving rise to the
request for indemnification, the requisite determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or
an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however,
that such sixty (60)-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making such determination with respect to entitlement
to indemnification in good faith requires such additional time to obtain or evaluate documentation and/or information relating thereto; and provided, further, that the foregoing 

  
 5 

 
provisions of this Section 6(f) shall not apply if the determination of entitlement to indemnification is to be made by the stockholders pursuant to
Section 6(b) of this Agreement and if (A) within fifteen (15) days after the conclusion of the Proceeding giving rise to the request for indemnification, the Board or the Disinterested Directors, if appropriate,
resolve to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such resolution and such determination is made thereat, or (B) a special meeting
of stockholders is called within fifteen (15) days after such resolution and such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made thereat. 

(g) Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to
indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee
and reasonably necessary to such determination. Any Independent Counsel, member of the Board or stockholder of the Company shall act reasonably and in good faith in making a determination regarding the Indemnitee’s entitlement to
indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company
(irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 

(h) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea
of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in
a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful. 

7. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is
not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made
pursuant to Section 6(b) of this Agreement within ninety (90) days after the conclusion of the Proceeding giving rise to the request for indemnification, (iv) payment of indemnification required by Section 4
is not made pursuant to this Agreement within thirty (30) days after receipt by the Company of a written request therefor or (v) payment of indemnification is not made within ten (10) days after a determination has been made that
Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in Court of Chancery of the State of
Delaware of Indemnitee’s entitlement to such indemnification. Indemnitee shall commence such proceeding seeking an adjudication within one hundred eighty (180) days following the date on which Indemnitee first has the right to commence
such proceeding pursuant to this Section 7(a). The Company shall not oppose Indemnitee’s right to seek any such adjudication. 

  
 6 

 (b) In the event that a determination shall have been made pursuant to
Section 6(b) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial
on the merits, and Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b). 

(c) If a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is entitled
to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 7, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a
material fact necessary to make Indemnitee’s misstatement not materially misleading in connection with the application for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) In the event that Indemnitee, pursuant to this Section 7, seeks a judicial adjudication of the Indemnitee’s
rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the Company, the Company shall pay on the Indemnitee’s behalf, in advance,
any and all expenses (of the types described in the definition of Expenses in Section 13 of this Agreement) unless the court determines that Indemnitee’s claims in such action were made in bad faith or were frivolous
or are prohibited by law. 
 (e) The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this
Section 7 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. 

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement
shall be required to be made prior to the final disposition of the Proceeding. 
 8.
Non-Exclusivity; Survival of Rights; Insurance; Primacy of Indemnification; Subrogation. 

(a) The rights of indemnification and advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights
to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders, a resolution of directors of the Company, or otherwise. No amendment, alteration or repeal of
this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in the Indemnitee’s Corporate Status prior to such amendment, alteration
or repeal. To the extent that a change in the DGCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Certificate of Incorporation, Bylaws and this Agreement, it is the intent of the
parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other right or remedy. 

  
 7 

 (b) To the extent that the Company maintains an insurance policy or policies providing
liability insurance for directors, officers, employees, or agents or fiduciaries of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that such person serves at the request of the
Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any director, officer, employee, agent or fiduciary under such policy or policies. If, at the
time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has directors’ and officers’ liability insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the insurers in
accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such proceeding
in accordance with the terms of such policies. 
 (c) [The Company hereby acknowledges that Indemnitee has certain rights to
indemnification, advancement of expenses and/or insurance provided by [ ● ] and certain of its affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of
first resort (i.e., its obligations to Indemnitee are primary and any obligation the Fund Indemnitors may have to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee is secondary), (ii) that it
shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by
the terms of this Agreement and the or Bylaws of the Company (or any other agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors, and, (iii) that it irrevocably waives,
relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the
Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee 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 Indemnitee against the Company. The Company and Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 8(c).] 

(d) [Except as provided in paragraph (c) above,] in the event of any payment under this Agreement, the Company shall be subrogated to the
extent of such payment to all of the rights of recovery of Indemnitee (other than against the Fund Indemnitors), who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are
necessary to enable the Company to bring suit to enforce such rights. 
 (e) [Except as provided in paragraph (c) above,] the Company
shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise.

  
 8 

 (f) [Except as provided in paragraph (c) above,] the Company’s obligation to
indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. 

9. Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this
Agreement to make any indemnity in connection with any claim made against Indemnitee: 
 (a) for which payment has actually been made to or
on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision[, provided, that the foregoing shall not affect the
rights of Indemnitee or the Fund Indemnitors set forth in Section 8(c) above]; or 
 (b) for an accounting of profits made from the
purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of state statutory law or common law; or 

(c) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any
Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation, (ii) the Company
provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law or (iii) the Proceeding is brought under Section 7 of this Agreement. 

10. Duration of Agreement. All agreements and obligations of the Company contained herein shall continue during the period Indemnitee is
an officer or director of the Company (or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) and shall continue thereafter so long
as Indemnitee shall be subject to any Proceeding (or any proceeding commenced under Section 7 hereof) by reason of the Indemnitee’s Corporate Status, whether or not he is acting or serving in any such capacity at the
time any liability or expense is incurred for which indemnification can be provided under this Agreement. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors
(including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives. 

  
 9 

 11. Security. To the extent requested by Indemnitee and approved by the Board, the
Company may at any time and from time to time provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to Indemnitee,
may not be revoked or released without the prior written consent of the Indemnitee. 
 12. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumes the obligations imposed on it hereby in
order to induce Indemnitee to serve as an officer or director of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as an officer or director of the Company. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof. 
 (c)
The Company shall not seek from a court, or agree to, a “bar order” which would have the effect of prohibiting or limiting the Indemnitee’s rights to receive advancement of expenses under this Agreement. 

13. Definitions. For purposes of this Agreement: 

(a) “Corporate Status” describes the status of a person who is or was a director, officer, employee, agent or
fiduciary of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that such person is or was serving at the express written request of the Company. 

(b) “Disinterested Director” means a director of the Company who is not and was not a party to the Proceeding in
respect of which indemnification is sought by Indemnitee. 
 (c) “Enterprise” shall mean the Company and any other
corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that Indemnitee is or was serving at the express written request of the Company as a director, officer, employee, agent or fiduciary. 

(d) “Expenses” shall include all reasonable attorneys’ fees, retainers, court costs, transcript costs, fees of
experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees and all other disbursements or expenses of the types customarily incurred in connection with prosecuting,
defending, preparing to prosecute or defend, investigating, participating, or being or preparing to be a witness in a Proceeding, or responding to, or objecting to, a request to provide discovery in any Proceeding. Expenses also shall include
Expenses incurred in connection with any appeal resulting from any Proceeding and any federal, state, local or foreign taxes imposed on the Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement, including
without limitation the premium, security for, and other costs relating to any cost bond, supersede as bond, or other appeal bond or its equivalent. Expenses, however, shall not include amounts paid in settlement by Indemnitee or the amount of
judgments or fines against Indemnitee. 

  
 10 

 (e) “Independent Counsel” means a law firm, or a member of a law
firm, that is experienced in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to
matters concerning Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the
foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an
action to determine Indemnitee’s rights under this Agreement. The Company agrees to pay the reasonable fees of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Expenses, claims, liabilities and
damages arising out of or relating to this Agreement or its engagement pursuant hereto. 
 (f) “Proceeding” includes
any threatened, pending or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought by or in the right of the
Company or otherwise and whether civil, criminal, administrative or investigative, in which Indemnitee was, is or will be involved as a party or otherwise, by reason of the Indemnitee’s Corporate Status, by reason of any action taken by the
Indemnitee or of any inaction on the Indemnitee’s part while acting in the Indemnitee’s Corporate Status; in each case whether or not he is acting or serving in any such capacity at the time any liability or expense is incurred for which
indemnification can be provided under this Agreement; including one pending on or before the date of this Agreement, but excluding one initiated by an Indemnitee pursuant to Section 7 of this Agreement to enforce the
Indemnitee’s rights under this Agreement. 
 14. Severability. The invalidity or unenforceability of any provision hereof shall

the other. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws. In the event any provision hereof conflicts with any
applicable law, such provision shall be deemed modified, consistent with the aforementioned intent, to the extent necessary to resolve such conflict. 

15. Modification and Waiver. No supplement, modification, termination or amendment of this Agreement shall be binding unless executed in
writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver.

any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered hereunder. The failure to so notify the Company shall not relieve the Company

VOTING AND SUPPORT AGREEMENT 

THIS VOTING AND SUPPORT AGREEMENT (the “Agreement”), is dated as of October 20, 2020, by and among Pioneer Natural
Resources Company, a Delaware corporation (“Parent”), and Q-Jagged Peak Energy Investment Partners, LLC (the “Holder”), as a stockholder of Parsley Energy, Inc., a Delaware
corporation (the “Company”). 
 W I T N E S S E T H: 

WHEREAS, Parent, the Company, Pearl First Merger Sub Inc., a Delaware corporation and a wholly-owned Subsidiary of Parent (“Merger Sub
Inc.”), Pearl Second Merger Sub LLC, a Delaware limited liability company and a wholly-owned Subsidiary of Parent (“Merger Sub LLC”), Pearl Opco Merger Sub LLC, a Delaware limited liability company and a wholly-owned
Subsidiary of Parent (“Opco Merger Sub LLC”), and Parsley Energy, LLC, a Delaware limited liability company (“Opco LLC”), are entering into an Agreement and Plan of Merger dated as of the date hereof
(as the same may be amended or supplemented from time to time, the “Merger Agreement”) providing for, among other things, (i) the merger of Merger Sub Inc. with and into the Company, with the Company continuing as the surviving
entity (the “Surviving Corporation”) (such merger, the “First Company Merger”), (ii) simultaneously with the First Company Merger, the merger of Opco Merger Sub LLC with and into Opco LLC, with Opco
LLC continuing as the surviving entity (such merger, the “Opco Merger”), and (iii) immediately following the First Company Merger and the Opco Merger, the merger of the Surviving Corporation with and into Merger Sub LLC,
with Merger Sub LLC continuing as the surviving entity (such merger, together with the First Company Merger and the Opco Merger, the “Mergers”), in each case, on the terms and subject to the conditions of the Merger Agreement; 

WHEREAS, the Holder is the Beneficial Owner (as defined below) of 65,412,650 shares of Class A common stock, par value $0.01 per share,
of the Company (the “Company Class A Common Stock”) (such shares of Company Class A Common Stock, the “Covered Securities”); 

WHEREAS, concurrently with the execution and delivery of the Merger Agreement, and as a condition and an inducement to Parent entering into
the Merger Agreement, the Holder is entering into this Agreement with respect to the Covered Securities; and 
 WHEREAS, Parent desires that
the Holder agree, and the Holder is willing to agree, subject to the limitations herein, not to Transfer (as defined below) any of its Covered Securities, and to vote its Covered Securities in a manner so as to facilitate consummation of the Mergers
and the other transactions contemplated by the Merger Agreement. 
 NOW, THEREFORE, in consideration of the mutual covenants,
representations, warranties and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows: 
  

 ARTICLE I 

GENERAL 

Section 1.1 Definitions. This Agreement is one of the “Voting Agreements” as defined in the Merger
Agreement. Capitalized terms used but not defined herein shall have the meanings set forth in the Merger Agreement. 
 “Beneficially
Own” or “Beneficial Ownership” has the meaning assigned to such term in Rule 13d-3 under the Exchange Act, and a Person’s beneficial ownership of securities shall be calculated
in accordance with the provisions of such Rule (in each case, irrespective of whether or not such Rule is actually applicable in such circumstance). For the avoidance of doubt, Beneficially Own and Beneficial Ownership shall also include record
ownership of securities. 
 “Beneficial Owners” shall mean Persons who Beneficially Own the referenced securities. 

“Permitted Lien” means (a) a collateral assignment or similar agreement, pledging or granting a Lien in Covered
Securities or a Person who directly or indirectly holds Covered Securities to a nationally recognized reputable banking organization in connection with any instrument governing Indebtedness of any Holder or any of its Affiliates, in each case as in
existence on the date of this Agreement, and (b) transfer restrictions of general applicability as may be provided under the Securities Act or other applicable securities Laws or as set forth in the Organizational Documents of the Holder or any
of its Affiliates. 
 “Transfer” means (a) any direct or indirect offer, sale, lease, assignment, encumbrance, loan,
pledge, grant of a security interest, hypothecation, disposition or other similar transfer (by operation of law or otherwise), either voluntary or involuntary, or entry into any contract, option or other arrangement or understanding with respect to
any offer, sale, lease, assignment, encumbrance, loan, pledge, hypothecation, disposition or other transfer (by operation of law or otherwise), of any Covered Securities owned by the Holder (whether beneficially or of record), including in each case
through the Transfer of any Person or any interest in any Person, or (b) in respect of any capital stock or interest in any capital stock, to enter into any swap or any other agreement, transaction or series of transactions that results in an
amount of Covered Securities subject to Article III that is less than the amount of Covered Securities subject to Article III as of the date hereof. 

ARTICLE II 
 AGREEMENT TO
RETAIN COVERED SECURITIES 
 2.1 Transfer and Encumbrance of Covered Securities. 

(a) From the date hereof until the earlier of the Termination Date (as defined below) and the Effective Time, the Holder shall not, with
respect to any Covered Securities Beneficially Owned by the Holder, (i) Transfer any such Covered Securities or (ii) deposit any such Covered Securities into a voting trust or enter into a voting agreement or arrangement with respect to
such Covered Securities or grant any proxy (except as otherwise provided herein) or power of attorney with respect thereto. 

  
 2 

 (b) Notwithstanding Section 2.1(a), the Holder may:
(i) Transfer Covered Securities to one or more Affiliates (A) who is a party to an agreement with Parent with substantially similar terms as this Agreement or (B) if, as a condition to such Transfer, the recipient agrees in writing to
be bound by this Agreement and delivers a copy of such executed written agreement to Parent prior to the consummation of such Transfer or (ii) Transfer Covered Securities with the prior written consent of Parent (which consent may be granted or
withheld by Parent in its sole discretion). 
 (c) Nothing in this Agreement shall prohibit direct or indirect transfers of equity or other
interests in a Holder to an Affiliate of the Holder. 
 2.2 Additional Purchases; Adjustments. The Holder agrees that any additional
shares of capital stock or other equity of the Company or Opco LLC that the Holder purchases or otherwise acquires or with respect to which the Holder otherwise acquires voting power after the execution of this Agreement and prior to the earlier of
the Termination Date and the Effective Time shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted the Covered Securities as of the date hereof (and shall be deemed “Covered Securities” for
all purposes hereof), and the Holder shall promptly notify Parent of the existence of any such after acquired Covered Securities. In the event of any stock split, stock dividend, merger, reorganization, recapitalization, reclassification,
combination, exchange of shares or the like of the capital stock of the Company or any similar transaction with respect to the equity of Opco LLC, as applicable, affecting the Covered Securities, the terms of this Agreement shall apply to the
resulting securities. 
 2.3 Unpermitted Transfers; Involuntary Transfers. Any Transfer or attempted Transfer of any Covered
Securities in violation of this Article II shall, to the fullest extent permitted by Law, be null and void ab initio, with no further action required by or on behalf of Parent, the Company or Opco LLC. In furtherance of the foregoing,
the Holder hereby agrees to authorize and instruct the Company or Opco LLC, as applicable, to instruct its transfer agent to enter a stop transfer order with respect to all of the Covered Securities. If any involuntary Transfer of any of the
Holder’s Covered Securities shall occur, the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold such Covered Securities subject to all of the
restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until valid termination of this Agreement. 

ARTICLE III 
 AGREEMENT
TO VOTE 
 3.1 Agreement to Vote. Prior to the earlier of the Termination Date and the Effective Time, the Holder irrevocably and
unconditionally agrees that such Holder shall, at any meeting (whether annual or special and whether or not an adjourned or postponed meeting), however called, of the stockholders of the Company or at any meeting or with respect to any written
consent of the Members (as defined in the Opco LLC Agreement) of Opco LLC, as applicable, appear at such meeting or otherwise cause the Covered Securities to be counted as present thereat for purpose of establishing a quorum and vote, or cause to be
voted at such meeting, all Covered Securities: 

  
 3 

 (a) in favor of adoption of the Merger Agreement and approving any other matters necessary
for consummation of the transactions contemplated by the Merger Agreement, including the Mergers (the “Transaction Matters”); and 

(b) against (i) any Acquisition Proposal or any other transaction, proposal, agreement or action made in opposition to adoption of the
Merger Agreement or in competition or inconsistent with the Mergers or matters contemplated by the Merger Agreement and (ii) any action that could reasonably be expected to impede, interfere with, delay, discourage, postpone or adversely affect
the Mergers or any of the other transactions contemplated by the Merger Agreement or this Agreement or any transaction that results in a breach in any material respect of any covenant, representation or warranty or other obligation or agreement of
the Company or any of its Subsidiaries (including Opco LLC) under the Merger Agreement. 
 Any attempt by the Holder to vote, consent or
express dissent with respect to (or otherwise to utilize the voting power of) the Covered Securities in contravention of this Section 3.1 shall be null and void ab initio. If the Holder is the Beneficial Owner, but
not the holder of record, of any Covered Securities, the Holder agrees to take all actions necessary to cause the holder of record and any nominees to vote (or exercise a consent with respect to) all of such Covered Securities in accordance with
this Section 3.1. 
 Notwithstanding anything herein to the contrary in this Agreement, this
Section 3.1 shall not require the Holder to be present (in person or by proxy) or vote (or cause to be voted), any of the Covered Securities to amend, modify or waive any provision of the Merger Agreement in a manner
that reduces the amount or changes the form of the Merger Consideration payable or imposes any material restrictions on or additional material conditions on the payment of the Merger Consideration or extends the Outside Date. Notwithstanding
anything to the contrary in this Agreement, the Holder shall remain free to vote (or execute consents or proxies with respect to) the Covered Securities with respect to any matter other than as set forth in Section 3.1(a)
and Section 3.1(b) in any manner the Holder deems appropriate, including in connection with the election of directors of the Company. 

3.2 Proxy. The Holder hereby irrevocably appoints as its proxy and attorney-in-fact, Parent, the executive officers of Parent and any person designated in writing by Parent, each of them individually, with full power of substitution and resubstitution, to consent to or vote
the Covered Securities as indicated in Section 3.1 above. The Holder intends this proxy to be irrevocable and unconditional during the term of this Agreement prior to the earlier of the Termination Date and the Effective
Time and coupled with an interest and will take such further action or execute such other instruments as may be reasonably necessary to effect the intent of this proxy, and hereby revokes any proxy previously granted by the Holder with respect to
the Covered Securities (and the Holder hereby represents that any such proxy is revocable). The proxy granted by the Holder shall be automatically revoked upon the earlier of the Termination Date and the Effective Time and Parent may further
terminate this proxy at any time at its sole election by written notice provided to the Holder. 

  
 4 

 ARTICLE IV 

ADDITIONAL AGREEMENTS 

4.1 Waiver of Appraisal Rights; Litigation. Unless (a) this Agreement is terminated in accordance with its terms or pursuant
to Section 6.5 or (b) the Merger Agreement is amended in a manner that reduces the amount or changes the form of the Merger Consideration payable or imposes any material restrictions on or additional material conditions on the payment of
the Merger Consideration or extends the Outside Date, in each case without the consent of the Holder, to the fullest extent permitted by Law, the Holder hereby irrevocably and unconditionally waives, and agrees not to exercise, any rights of
appraisal (including under Section 262 of the DGCL) relating to the Mergers that the Holder may have by virtue of the ownership of any Covered Securities. The Holder further agrees not to commence, join in, and agrees to take all actions
necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, Merger Sub Inc., Merger Sub LLC, Opco Merger Sub LLC, Opco LLC, or the Company or any of their respective Affiliates and each
of their successors or directors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the transactions contemplated hereby or thereby, including any claim (a) challenging the
validity of, or seeking to enjoin the operation of, any provision of this Agreement or the Merger Agreement (including any claim seeking to enjoin or delay the Closing) or (b) alleging a breach of any fiduciary duty of the Company Board in
connection with the negotiation and entry into the Merger Agreement or the transactions contemplated thereby, and hereby irrevocably waives any claim or rights whatsoever with respect to any of the foregoing. 

4.2 Further Assurances. The Holder agrees that, during the term of this Agreement, the Holder shall and shall cause such Holder’s
controlled Affiliates to take no action that would reasonably be expected to adversely affect or delay the ability to perform the Holder’s respective covenants and agreements under this Agreement. 

4.3 Fiduciary Duties. The Holder is entering into this Agreement solely in such Holder’s capacity as the record or
Beneficial Owner of the Covered Securities and nothing herein is intended to or shall limit or affect any actions taken by the Holder or any of the Holder’s designees, as applicable, serving in his or her capacity as a director of the Company
(or a Subsidiary of the Company). The taking of any actions (or failures to act) by the Holder or the Holder’s designees, as applicable, serving as a director of the Company or a Subsidiary of the Company (in such capacity as a director) shall
not be deemed to constitute a breach of this Agreement. 

  
 5 

 ARTICLE V 

REPRESENTATIONS AND WARRANTIES OF HOLDER 

5.1 Representations and Warranties. The Holder hereby represents and warrants as follows: 

(a) Ownership. The Holder has, with respect to the Covered Securities, and at all times during the term of this Agreement will continue
to have, Beneficial Ownership of, good and valid title to and full and exclusive power to vote, issue instructions with respect to the matters set forth in Article III, agree to all of the matters set forth in this Agreement and to Transfer
the Covered Securities. Other than the 20,374 unvested Restricted Stock Units and 3,589 shares of Company Class A Common Stock issued upon the vesting of Restricted Stock Units held for the benefit of the Holder, the Covered Securities
constitute all of the shares of Company Class A Common Stock owned of record or Beneficially Owned by the Holder as of the date hereof, and all of the Covered Securities are held by the Holder free and clear of all Liens, other than any
Permitted Liens. Other than this Agreement and any Permitted Liens, (i) there are no agreements or arrangements of any kind, contingent or otherwise, to which the Holder is a party obligating the Holder to Transfer or cause to be Transferred to
any person any of the Covered Securities and (ii) no Person has any contractual or other right or obligation to purchase or otherwise acquire any of the Covered Securities. 

(b) Organization; Authority. The Holder is an entity duly organized, validly existing and in good standing under the Laws of its
jurisdiction of formation. The Holder has full power and authority and is duly authorized to make, enter into and carry out the terms of this Agreement and to perform the Holder’s obligations hereunder. This Agreement has been duly and validly
executed and delivered by the Holder and (assuming due authorization, execution and delivery by Parent) constitutes a valid and binding agreement of the Holder, enforceable against the Holder in accordance with its terms (except in all cases as such
enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar Laws affecting creditors’ rights generally and by general principles of equity (regardless of whether considered in a proceeding in equity
or at law)), and no other action is necessary to authorize the execution and delivery by the Holder or the performance of the Holder’s obligations hereunder. 

(c) No Violation. The execution, delivery and performance by the Holder of this Agreement will not (i) violate any provision of any
Law applicable to the Holder; (ii) violate any order, judgment or decree applicable to the Holder or any of its Affiliates; or (iii) conflict with, or result in a breach or default under, any agreement or instrument to which the Holder or
any of its Affiliates is a party or any term or condition of its certificate of incorporation, bylaws, certificate of formation, limited liability company agreement or comparable organizational documents, as applicable, except where such conflict,
breach or default would not reasonably be expected to, individually or in the aggregate, have an adverse effect on the Holder’s ability to satisfy the Holder’s obligations hereunder. 

(d) Consents and Approvals. The execution and delivery by the Holder of this Agreement, and the performance of the Holder’s
obligations hereunder, do not require the Holder or any of its Affiliates to obtain any consent, approval, authorization or permit of, or to make any filing with or notification to, any person or Governmental Entity, except such filings and
authorizations as may be required under the Exchange Act. 
 (e) Absence of Litigation. To the knowledge of the Holder, as of the date
hereof, there is no action, suit, investigation, complaint or other proceeding pending against, or threatened in writing against the Holder that would prevent the performance by the Holder of its obligations under this Agreement on a timely basis.

  
 6 

 (f) Absence of Other Voting Agreements. Except as contemplated by this Agreement, the
Holder (i) has not entered into, and shall not enter into at any time prior to the earlier of the Termination Date and the Effective Time, any voting agreement or voting trust with respect to the Covered Securities and (ii) has not
granted, and shall not grant at any time prior to earlier of the Termination Date and the Effective Time, a proxy or power of attorney with respect to the Covered Securities, in either case, which is inconsistent with the Holder’s obligations
pursuant to this Agreement. Other than with respect to any Permitted Liens, none of the Covered Securities are subject to any pledge agreement pursuant to which the Holder does not retain sole and exclusive voting rights with respect to the Covered
Securities subject to such pledge agreement at least until the occurrence of an event of default under the related debt instrument. 

ARTICLE VI 

MISCELLANEOUS 
 6.1 No
Solicitation. The Holder agrees that such Holder shall not, and shall not permit or authorize any of such Holder’s controlled Affiliates and shall use commercially reasonable efforts to not permit or authorize any of such Holder’s or
such Holder’s controlled Affiliates’ Representatives to, directly or indirectly, take any of the actions listed in clauses (i) or (ii) of Section 5.2(a) of the Merger Agreement (without giving effect to any amendment or
modification of such clauses after the date hereof). The Holder shall, and shall cause such Holder’s controlled Affiliates and shall use commercially reasonable efforts to cause such Holder’s and such Holder’s controlled
Affiliates’ Representatives to, immediately cease and cause to be terminated all existing discussions and negotiations with any Person conducted heretofore with respect to any Acquisition Proposal or potential Acquisition Proposal. In addition,
the Holder agrees to be subject to Section 5.2(e) of the Merger Agreement (without giving effect to any amendment or modification of such clauses after the date hereof) as if the Holder were the “Company” thereunder. Notwithstanding
the foregoing, to the extent the Company complies with its obligations under Section 5.2 of the Merger Agreement and participates in discussions or negotiations with a Person regarding an Acquisition Proposal, the Holder or any of such
Holder’s controlled Affiliates and/or such Holder’s and such Holder’s controlled Affiliates’ Representatives may engage in discussions or negotiations with such Person to the extent that the Company can act under Section 5.2
of the Merger Agreement. 
 6.2 Non-Recourse. This Agreement may only be enforced against,
and any claim or cause of action based upon, arising out of, or related to this Agreement or the transactions contemplated by this Agreement may only be brought against, the entities that are expressly named as parties hereto and then only with
respect to the specific obligations set forth herein with respect to such party. Except to the extent a named party to this Agreement (and then only to the extent of the specific obligations undertaken by such named party in this Agreement and not
otherwise), no past, present or future director, manager, officer, employee, incorporator, member, partner, equityholder, Affiliate, agent, attorney, advisor, consultant or Representative or Affiliate of any of the foregoing (each, a “Holder
Related Party”) shall have any liability (whether in contract, tort, equity or otherwise) for any one or more of the representations, warranties, covenants, agreements or other obligations or liabilities of or made under this Agreement or
in respect of any oral representations made or alleged to have been made in connection herewith (whether for indemnification or otherwise) or of or for any claim based on, arising out of, or related to this Agreement or the transactions contemplated
by this Agreement. Parent acknowledges that no Holder nor any Holder Related Party has made, and Parent has not relied upon, any representation related to the matters contemplated by this Agreement, except as set forth in Article V. 

  
 7 

 6.3 No Ownership Interest. Nothing contained in this Agreement shall be deemed to
vest in Parent any direct or indirect ownership or incidence of ownership of or with respect to the Covered Securities. All rights, ownership and economic benefits of and relating to the Covered Securities shall remain vested in and belong to the
Holder, and Parent shall not have any authority to manage, direct, restrict, regulate, govern or administer any of the policies or operations of the Company or Opco LLC or exercise any power or authority to direct the Holder in the voting or
disposition of any Covered Securities, except as otherwise expressly provided herein. 
 6.4 Disclosure. The Holder consents to and
authorizes the publication and disclosure by the Company and Parent of the Holder’s identity and holding of Covered Securities, and the terms of this Agreement (including, for avoidance of doubt, the disclosure of this Agreement), in any press
release, the Form S-4, the Joint Proxy Statement and any other disclosure document required in connection with this Agreement, the Merger Agreement, the Mergers and the transactions contemplated by the Merger
Agreement. 
 6.5 Termination. This Agreement shall terminate upon the date the Merger Agreement is validly terminated in accordance
with its terms (such date, the “Termination Date”). Neither the provisions of this Section 6.5 nor the termination of this Agreement shall relieve (x) any party hereto from any liability of such party
to any other party incurred prior to such termination or (y) any party hereto from any liability to any other party arising out of or in connection with a breach of this Agreement. Nothing in the Merger Agreement shall relieve the Holder from
any liability arising out of or in connection with a breach of this Agreement. 
 6.6 Amendment. This Agreement may not be amended,
modified or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing specifically designated as an amendment hereto, signed on behalf of each party hereto. 

6.7 Reliance. The Holder understands and acknowledges that Parent is entering into the Merger Agreement in reliance upon the
Holder’s execution and delivery of this Agreement. 
 6.8 Extension; Waiver. The parties hereto may, to the extent permitted by
applicable Law: 
 (a) extend the time for the performance of any of the obligations or acts of the other party hereunder; 

(b) waive any inaccuracies in the representations and warranties of the other party contained herein or in any document delivered pursuant
hereto; or 
 (c) waive compliance with any of the agreements or conditions of the other party contained herein; 

provided, however, that, in each case, such waiver is made in writing and signed by the party (or parties) against whom the waiver is to be
effective. 

  
 8 

 Notwithstanding the foregoing, no failure or delay by Parent in exercising any right hereunder shall operate
as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder. No agreement on the part of a party hereto to any such extension or waiver shall be valid unless set forth in
an instrument in writing signed on behalf of such party. No waiver by any of the parties hereto of any default, misrepresentation or breach of representation, warranty, covenant or other agreement hereunder, whether intentional or not, shall be
deemed to extend to any prior or subsequent default, misrepresentation or breach or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. 

6.9 Expenses. All fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid
by the party incurring such fees or expenses, whether or not the Mergers are consummated. 
 6.10 Notices. All notices and other
communications hereunder shall be in writing and shall be deemed duly given (a) on the date of delivery if delivered personally, or if by e mail, upon written confirmation of receipt by e mail or otherwise; provided, that each notice

6.11 Interpretation. When a reference is made in this Agreement to a Section or Article, such reference shall be to a Section or
Article of this Agreement unless otherwise indicated. The words “this Section,” “this subsection” and words of similar import, refer only to the Sections or subsections hereof in which such words occur. The headings contained in
this Agreement are for convenience of reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. All words used in this Agreement will be construed to be of such gender or number as the circumstances
require. The word “including” and words of similar import when used in this Agreement will mean “including, without limitation,” unless otherwise specified. The words “hereof,” “herein” and
“hereunder” and words of similar import when used in this Agreement shall refer to the Agreement as a whole and not to any particular provision in this Agreement. The term “or” is not exclusive. The word “will” shall be
construed to have the same meaning and effect as the word “shall. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends and such phrase shall not mean simply
“if.” References to “days” mean calendar days; when calculating the period of time within which, or following which, any act is to be done or step taken pursuant to this Agreement, the date that is the reference day in
calculating such period shall be excluded and if the last day of the period is a non-Business Day, the period in question shall end on the next Business Day or if any action must be taken hereunder on or by a
