position, as lawfully requested by the Board of Directors. During the Term of this Agreement, Executive shall use his best efforts to serve the Company faithfully, diligently and competently and
to the best of his ability, and to devote his full time business hours, energy, ability, attention and skill to the business of the Company; provided, however, that the foregoing is not intended to preclude Executive from noncompetitive

however, under any circumstances, provide services or advice in any capacity whatsoever for or on behalf of any entity that competes with or is competitive with the Company.

estate) or his dependents may be entitled under the employee benefit plans or programs of the Company, paid in accordance with the terms of the applicable plans or programs (the amounts described in clauses (a) through (d) hereof being referred

 5.2 Termination by Executive for Other Than Good Reason. In the event
Executive terminates his employment for other than Good Reason, Executive shall be entitled to receive the Accrued Rights, but following the Termination Date, Executive shall have no further rights to any other compensation or benefits under
this Agreement, including without limitation any severance or continuation of benefits or otherwise. Executive shall provide the Company sixty (60) days’ prior written notice of his intention to terminate his employment with the Company
pursuant to this Section 5.2. 
 5.3 Termination by the Company for Cause. In the event the Company terminates his

 5.4 Termination by the Company Other Than for Death, Disability or Cause or by Executive
for Good Reason. If Executive’s employment is terminated by the Company for reasons other than death, Disability or Cause, or is terminated by Executive for Good Reason, Executive shall be entitled to receive (a) a monthly
severance payment in an amount equal to the sum of (I) the annualized average of the last three (3) years of the Executive’s Base Salary plus Bonus, in effect as of immediately prior to the date of such termination, divided by
(II) twelve (the “Severance Benefits”), for the period set forth in Section 5.6; and (b) the Accrued Rights. Notwithstanding anything herein to the contrary, Executive may terminate his employment hereunder for
Good Reason within a period of time not to exceed ninety (90) days following the initial existence of the event(s) that constitute Good Reason. For purposes of this Agreement, Good Reason shall not occur unless Executive gives written notice to
the Company within thirty (30) days of the occurrence of any of the events listed under the definition of Good Reason in Section 1 hereof and such event remains uncured sixty (60) days after the Company’s receipt of such notice.
Such termination shall occur immediately following expiration of the cure period to the extent such event remains uncured. 
 5.5
Termination by Mutual Consent. Notwithstanding any of the foregoing provisions of this Section 5, if at any time during the course of this Agreement the parties by mutual consent decide to terminate Executive’s
employment, they may do so by separate agreement setting forth the terms and conditions of such termination.

Severance. Unless otherwise set forth herein, any Severance Benefits owed to Executive pursuant to Section 5 hereof shall be paid out monthly by the Company for a minimum of one (1) year after the Termination Date and,
subject to delivery of a Severance Notice pursuant to this Section 5.6, during the entire Restricted Period (as defined below) commencing on the sixtieth (60th) day following the Termination
Date and in accordance with the Company’s standard payroll schedule and practices; provided, however, that Severance Benefits owed to Executive shall immediately cease and no Severance Benefits shall be paid by the Company to Executive if at
any time after the first anniversary of the Termination Date, the Company provides written notice (such notice, the “Severance Notice”) to Executive stating (a) the obligations and restrictions set forth in
Section 6.1 of this Agreement no longer apply to Executive and (b) the final end date of the Restricted Period. Executive acknowledges and agrees that no Severance Benefits will be paid by the Company to Executive following delivery of a
Severance Notice to Executive. 
 5.7 Release of Claims; Offsets. As a condition to the receipt of any Severance Benefits,
Executive shall be required to execute, and not subsequently revoke, within sixty (60) days following the termination of his employment a release in a form reasonably acceptable to the Company of all claims arising out of his employment or the
termination thereof. After the first anniversary of the Termination Date, Severance Benefits, if any, may also be offset by any earnings of Executive after the first anniversary of the Termination Date from other employment. While receiving
Severance Benefits, Executive shall notify the Company upon obtaining other employment and provide evidence of base salary and/or bonus and incentive payments that Executive may receive from new employment while receiving Severance Benefits. 

5.8 Cooperation with Company after Termination of Employment. Following termination of Executive’s employment for any
reason, Executive shall reasonably cooperate with the Company in all matters relating to the winding up of his pending work on behalf of the Company including, but not limited to, any litigation in which the Company is involved and the
orderly transfer of any such pending work to other employees of the Company as may be 

  
 5 

 
designated by the Company. The Company shall reasonably compensate Executive for services rendered pursuant to this Section 5.8 at a rate to be determined by the parties. In addition, the
Company shall reimburse Executive for any reasonable out-of-pocket expenses he incurs in performing any work on behalf of the Company following the termination of his
employment. 
 6. NON-SOLICITATION &
NON-COMPETITION 
 6.1 Non-Compete.
Executive agrees that during the Term and for three (3) years following the Termination Date (the “Restricted Period”), Executive shall not, anywhere in the areas where the Company conducts business (or has
expanded resources or time to plan the conduct of business) during the Term, including, but not limited to the United States (the “Restricted Territory”), directly or indirectly, own, manage, operate, join, control or
participate in the ownership, management, operation or control of, or be an officer or an employee of any business or organization that, directly or indirectly (i) provides medical or health care services of any type to Medicare beneficiaries,
or (ii) offers or manages any plan contracting with the Medicare Advantage program or with any dual Medicare/Medicaid program or provides administrative or other services to such plan (each, a “Restricted Business”). The
foregoing shall not restrict Executive from owning up to 1% of any class of securities of any person engaged in a Restricted Business if such securities are listed on any national or regional securities exchange or have been registered under
Section 12(g) of the Securities Exchange Act of 1934, as amended, as long as such securities are held solely as a passive investment and not with a view to influencing, controlling or directing the affairs of such person. Executive acknowledges
and agrees that the Restricted Period may be for a period less than three (3) years following the Termination Date if (and only if) the Company delivers a Severance Notice pursuant to Section 5.6 but in no event shall such period be for a
period less than one year following the Termination Date. 
 6.2 Non-Solicitation.
Executive agrees that during the Restricted Period, Executive will not, directly or indirectly, for himself or on behalf of or in conjunction with any other person, (i) solicit, induce, attempt to solicit or induce, or hire or
attempt to hire any person that is an employee of the Company or was within twelve (12) months prior to the Termination Date; provided, however, this Section 6.2 shall not be breached by a solicitation to the general public or through
general advertising and Executive may solicit for employment any person who at the Termination Date had not been an employee of the Company at any time within six (6) months preceding such date or whose employment with the Company had
terminated more than six (6) months prior to Executive’s solicitation of such person or (ii) solicit, advise or encourage any person, firm, government agency or corporation (a “Customer”) (including without
limitation any potential customer of the Company that is engaged in discussion with the Company to do business with the Company), to withdraw, curtail or cancel its business (or potential business) with the Company. 

6.3 Non-Disparagement. During the Term and thereafter, Executive agrees that he
will not, at any time, make, directly or indirectly, any oral or written statements that are disparaging of the Company, its business, its products or services, or any of its present or former officers, directors, members, stockholders, managers or
employees. 

  
 6 

 6.4 Reasonable Limitation and Severability. The parties agree that the
above restrictions on competition are (i) appropriate and reasonable given Executive’s role with and knowledge of the Company, and are necessary to protect the interests of the Company and (ii) completely severable and
independent agreements supported by good and valuable consideration and, as such, shall survive the termination of this Agreement for any reason whatsoever. Executive acknowledges that Executive has carefully considered the terms of this Agreement,
including the restrictive covenants set forth in this Section 6, and acknowledges that if this Agreement is enforced according to its terms, Executive will be able to earn a reasonable living in commercial activities unrelated to the business
of the Company in locations satisfactory to Executive. Executive also acknowledges that the restrictive covenants set forth in this Section 6 are a vital part of and are intrinsic to the ongoing operations of the Company, in light of the nature
of the business of the Company and the unique position, skills and knowledge of Executive with the Company. The parties further agree that any invalidity or unenforceability of any one or more of such restrictions on competition shall not render
invalid or unenforceable any remaining restrictions on competition. Additionally, should a court of competent jurisdiction determine that the scope of any provision of this Section 6 is too broad to be enforced as written, the parties hereby
authorize the court to reform the provision to such narrower scope as it determines to be reasonable and enforceable and the parties intend that the affected provision be enforced as so amended. Executive acknowledges and agrees that to the extent
Executive has breached or is in breach of any of the covenants set forth in Sections 6.1 or 6.2, the Restricted Period shall be extended by an amount of time equal to the duration of such breach. 

6.5 Confidential Information. Executive acknowledges and agrees that the customers, business connections, customer lists,
procedures, operations, techniques and other aspects of and information about the business of the Company (the “Confidential Information”) are established at great expense and protected as confidential
information and provide the Company with a substantial competitive advantage in conducting its business. Executive further acknowledges and agrees that by virtue of his employment with the Company, he has had access to and will have access to, and
has been entrusted with and will be entrusted with Confidential Information, and that the Company would suffer great loss and injury if Executive would disclose this information or use it in a manner not specifically authorized by the Company.
Therefore, Executive agrees that during the Term and at all times thereafter, he will not, directly or indirectly, either individually or as an employee, agent, partner, shareholder, owner trustee, beneficiary,
co-venturer distributor, consultant or in any other capacity, use or disclose or cause to be used or disclosed any Confidential Information, unless and to the extent that any such information becomes generally
known to and available for use by the public other than as a result of Executive’s acts or omissions. Executive shall deliver to the Company at the termination of the Term, or at any other time the Company may request, all memoranda, notes,
plans, records, reports, computer discs, flash drives, printouts and software and other documents and data (and copies thereof) in any media form relating to the Confidential Information, Work Product (as defined below) or the business of the
Company which he may then possess or have under his control. Executive acknowledges and agrees that all inventions, innovations, improvements, developments, methods, designs, analyses, drawings, reports and all similar or related information
(whether or not patentable) that relate to the Company’s actual or anticipated business research and development or existing or future products or services and that are conceived, developed or made by the Executive while employed by the Company
(“Work Product”) belong to the Company.

DEMAND, ACTION, CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR (II) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT WHETHER NOW EXISTING OR HEREAFTER ARISING, AND

 7.13 Taxes & IRC Section 409A Matters.
The Company may withhold from any payment hereunder such state, federal or local income, employment or other taxes and other legally mandated withholdings as it reasonably deems appropriate. The Company makes no representation about the tax
treatment or impact of any payment(s) hereunder. The intent of the parties is that payments and benefits under this Agreement comply with Section 409A of the Code, as amended (“Section 409A”), to the extent
subject thereto, and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted and administered to be in compliance therewith. Notwithstanding anything herein to the contrary: (i) if at the time of Executive’s
termination of employment with the Company, Executive is a “specified employee” as defined in Section 409A and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of
employment is necessary in order to prevent any accelerated or additional tax under Section 409A, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such payments or
benefits ultimately paid or provided to Executive) until the date that is six (6) months following Executive’s termination of employment with the Company (or the earliest date as is permitted under Section 409A); (ii) if any other
payments of money or other benefits due to Executive hereunder could cause the application of an accelerated or additional tax under Section 409A, such payments or other benefits shall be deferred if deferral will make such payment or other
benefits compliant under Section 409A, or otherwise such payment or other benefits shall be restructured, to the extent possible, in a manner determined by the Company that does not cause such an accelerated or additional tax; (iii) to the
extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A, Executive shall not be considered to have terminated employment with the Company for purposes of this Agreement and no payment shall be due to
Executive under this Agreement until Executive would be considered to have incurred a “separation from service” from the Company within the meaning of Section 409A; and (iv) each amount to be paid or benefit to be provided to
Executive pursuant to this Agreement, which constitute deferred compensation subject to Section 409A, shall be construed as a separate identified payment for purposes of Section 409A. To the extent required to avoid an accelerated or
additional tax under Section 409A, amounts reimbursable to Executive under this Agreement shall be paid to Executive on or before the last day of the year following the year in which the expense was incurred and the amount of expenses eligible
for reimbursement (and in-kind benefits provided to Executive) during any one year may not affect amounts reimbursable or provided in any subsequent year. Neither the Company nor any of its employees or
representatives shall have any liability to Executive with respect to Section 409A. 
 7.14 Survival. Except as otherwise
expressly provided in this Agreement, all covenants, representations and warranties, express or implied, in addition to the provisions of Sections 6 and 7 of this Agreement, shall survive the termination of this Agreement. 

7.15 Review by Counsel. Executive has been advised that Executive should consult with his own legal advisor prior to executing
this Agreement, and Executive acknowledges that he has had the opportunity to consult with and review the terms of this Agreement with counsel prior to execution of this Agreement.

parties hereto, except this cost may be waived by the Employer where such fees are discouraged or prohibited by applicable law. In the event the Parties fail to agree on a mediator, or mediation is unsuccessful in resolving the claim or controversy

(“4X Units”). The Hurdle Value of the 2X Units and 4X Units shall be subject to adjustments in accordance with Section IV.B; provided that, in no event shall the Hurdle Value of any Incentive Unit be lower than the Fair Market Value
of the Company as of the date of grant of such Incentive Unit. For the avoidance of doubt, the 2X Units and 4X Units shall become available for issuance on a proportional basis such that an equal percentage of the 2X Units and 4X Units shall be
awarded simultaneously. Notwithstanding anything to the contrary herein or otherwise, as of any date of determination, in no event shall the Hurdle Value be deemed to have been met with respect to the 2X Units and the 4X Units, unless and until each
Sponsor realizes cash proceeds in respect of the Units representing their respective Invested Equity equal to at least two (2) times and four (4) times its Invested Equity, respectively. If, after the Effective Date, any Incentive Unit is
forfeited, or if any Incentive Unit has expired, terminated or been cancelled or repurchased for any reason whatsoever, and in either such case no Participant has received any benefits of ownership with respect to such forfeited, expired,
terminated, cancelled or repurchased Incentive Unit, then such Incentive Unit shall again be available to be awarded hereunder by the Board, in its sole discretion. 

B. Adjustments. 
 1. In
the event the Board determines that any sale or other extraordinary distribution (whether in the form of cash, Units, securities or other property), recapitalization, reclassification, reorganization or “reorganization event” (in
accordance with Section 3.7 of the LLC Agreement), change to organizational form, merger, consolidation, split-up, spin-off, combination, repurchase, liquidation or “deemed liquidation” (in
accordance with Section 3.8 of the LLC Agreement), dissolution, transfer, exchange, or other unusual event or transaction (including changes to capital structure and acquisitions and dispositions of businesses of the Company) affects the
Incentive Units such that an adjustment is necessary in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Incentive Plan, then the Board shall make adjustments to the Incentive
Plan and Incentive Units in such manner as the Board determines appropriate and equitable, including adjusting the number of Incentive Units and/or the terms of any outstanding awards made under the Incentive Plan taking into account the Hurdle
Value. For the avoidance of doubt, the Company shall adjust the Hurdle Value to take into account the issuance of additional Units or additional capital investments into the Company. Adjustments made by the Board pursuant to this Article IV shall be
conclusive and binding for all purposes. 

  
 15 

 2. In addition, without limiting the generality of Article IV.B.1, in the event of any of
the following: (i) a Sale pursuant to which some or all Members are entitled to receive, in exchange for their Units, a form of consideration other than stock or other equity interests of the surviving entity; (ii) a Sale that is deemed to
be a Drag-Along Sale (as defined in the LLC Agreement); or (iii) the Company enters into a written agreement to undergo an event described in clauses (i) or (ii) above, the Board in its sole discretion, may (I) cancel all or any
portion of any outstanding Incentive Units and pay to the affected Participant, in cash or capital stock (or other equity interests), or any combination thereof, the Fair Market Value of the Incentive Units which are then vested and/or
(II) convert all or some of the outstanding vested Incentive Units into other Units or otherwise make provision for the outstanding vested Incentive Units to be Transferred in such transaction, in each case of (I) or (II) above, as
determined by the Board in a manner generally consistent with the treatment of other Units in such event, taking into consideration the relative rights of all Units, including the Hurdle Value applicable to Incentive Units; and provided, that in the
case of an event described in clause (i) above, the Board shall take one of the actions described in clause (I) or (II) above. For the avoidance of doubt, under no circumstance shall the Participant be entitled to any payment or conversion
in respect of an Incentive Unit unless the applicable Hurdle Value for such Incentive Unit has been achieved. 
 3. Furthermore, and without
limiting the generality of Article IV.B.1, upon the occurrence of an Initial Offering, the Board may, in its discretion, (i) cause the exchange of Incentive Units for units or shares of common stock or other equity securities and apply the vesting
provisions applicable to the Incentive Units to such shares of common stock or other equity securities; (ii) adjust the number of Incentive Units issued under the Incentive Plan or under any particular award; (iii) adjust the Hurdle Value
applicable to any Incentive Units; and/or (iv) cancel all or any portion of the Incentive Units in exchange for payment to the Participant in cash or capital stock (or other equity interests) or any combination thereof, of the Fair Market Value
of the Incentive Units; in each case, determined by the Board in a manner generally consistent with the treatment of other Units, taking into consideration the relative rights of all Units, including the Hurdle Value applicable to Incentive Units.

 XX. Eligibility. Any Person who is an officer, director, employee, consultant, or independent contractor providing services to the
Company or its Affiliates shall be eligible to be designated as a Participant in the Incentive Plan by the Board. 
 XXI. Incentive Unit
Awards. The Board may issue or approve the Transfer of Incentive Units to a Participant pursuant to an Incentive Unit Agreement, upon such terms as the Board deems appropriate and consistent with the Incentive Plan. The following provisions are
applicable to Incentive Units, except as specified otherwise in the applicable Incentive Unit Agreement: 
 A. General Requirements for
Incentive Units. Incentive Units will be issued pursuant to an Incentive Unit Agreement. The Board may establish vesting and other conditions under which restrictions on Incentive Units shall lapse over a period of time or according to such
other criteria as the Board deems appropriate in its sole discretion, and which shall be set forth in the applicable Incentive Unit Agreement. 

B. Number of Incentive Units; Hurdle Value. The Board shall determine the number of Incentive Units to be issued or transferred and the
restrictions applicable to such award, as well as the Hurdle Value applicable to such award. 

  
 16 

 C. Requirement of Employment. Except as otherwise set forth in an applicable
Incentive Unit Agreement, (i) if a Participant’s employment with the Company and its Affiliates is terminated for any reason, all Incentive Units granted to such Participant which remain unvested shall be cancelled and forfeited without
consideration, and (ii) if a Participant’s employment is terminated by the Company or an Affiliate for Cause, all Incentive Units granted to such Participant, whether vested or unvested, shall be cancelled and forfeited without
consideration. Notwithstanding any provision of the Incentive Plan to the contrary, upon the termination of a Participant’s employment with the Company and its Affiliates, such Participant’s vested Incentive Units may be subject to
cancellation and/or repurchase by the Company in the manner and for the consideration provided in such Participant’s Incentive Unit Agreement. The Board may provide for complete or partial exceptions to the requirements of this Article VI.C as
it deems appropriate in its sole discretion. 
 D. Restrictions on Transfer. Except as provided in the LLC Agreement, the applicable
Incentive Unit Agreement or consented to by the Board, no Participant shall Transfer, directly or indirectly, any Incentive Unit awarded under the Incentive Plan, and any such Transfer shall be void and unenforceable against the Company or any of
its Affiliates. 
 E. Non-Voting. The Incentive Units shall not grant the holder thereof any
right to vote. 
 F. Right to Repurchase Units. To the extent provided in any Incentive Unit Agreement, the Company shall have the
right, in its sole discretion, to make a payment to the holder of an outstanding Incentive Unit under the Incentive Plan, whether or not then vested, of the Fair Market Value of such Incentive Unit in consideration for the cancellation of such
Incentive Unit. 
 XXII. Future Award of Additional Classes of Units. The Board reserves the right, from time to time in the future,
and in its sole discretion, to award additional classes of Units to Participants. In the event of any such award, the terms of the Incentive Plan shall be applied without the need of any further amendments thereto (and without any need to obtain the
consent of any existing Participants), as if such additional classes of Units were Incentive Units described hereunder, except as the applicable award agreements with respect to such additional classes of Units may otherwise provide. 

XXIII. Amendment and Termination. The Board may amend, alter, suspend, discontinue, or terminate the Incentive Plan or any portion
thereof at any time; provided, that any such amendment, alteration, suspension, discontinuance or termination that would materially adversely affect the rights of any Participant shall not to that extent be effective without the written
consent of a majority-in-interest of all such adversely affected Participants, taking into account, for such purpose, all such outstanding Incentive Units, whether or
not then vested; provided, further, that such consent shall not be required with respect to an amendment made to conform the Incentive Plan to the LLC Agreement, as currently in effect or as such agreement may subsequently be amended,
or with respect to an amendment made to comply with applicable law. Nothing in the Incentive Plan or in any Incentive Unit Agreement shall require the consent of any holder of any Incentive Unit to any amendment of the LLC Agreement. 

  
 17 

 XXIV. General Provisions. 

A. No Rights to Awards. No Person shall have any claim to receive any award under the Incentive Plan. There is no obligation for
uniformity of treatment of Participants regarding the number of Incentive Units awarded. The terms and conditions of awards made under the Incentive Plan need not be the same with respect to each Participant. 

B. Joinder to LLC Agreement; Section 83(b) Election. Unless the Board determines otherwise, as a condition
subsequent to the issue or transfer of any Incentive Unit, each Participant will be required to (i) become a party to the LLC Agreement and (ii) make a timely, valid election under Section 83(b) of the Code to both the Internal
Revenue Service and the Company within 30 days after such issuance or transfer. The issuance or transfer of Incentive Units to any Participant who either fails to become party to the LLC Agreement and/or fails to make such a valid and timely
election under Section 83(b) of the Code shall be void ab initio. 
 C. Tax Withholding. A Participant shall be required
to pay to the Company or any Affiliate, and the Company and its Affiliates shall have the right and are hereby authorized to withhold from any payment due or transfer made under any Incentive Unit, under the Incentive Plan or from any other amount
owing to a Participant (including in connection with any Transfers), the amount (in cash, securities or other property) of any applicable U.S. Federal, state, local or non-U.S. withholding taxes in respect of
an Incentive Unit or any payment or transfer under an Incentive Unit or the Incentive Plan and to take such other action as may be necessary in the opinion of the Board to satisfy all obligations for the payment of such taxes. 

D. Profits Interest Designation. Unless otherwise determined by the Board upon grant of an award, it is intended that the Incentive
Units granted hereunder will constitute “profits interests” for all U.S. Federal tax purposes. 
 E. Section 409A. The
Incentive Plan is intended not to be a nonqualified deferred compensation plan under Section 409A of the Code; provided, however, to the extent that the Incentive Plan or any part thereof is deemed to be a nonqualified deferred compensation
plan subject to Section 409A of the Code, (i) the provisions of the Incentive Plan shall be interpreted in a manner to the maximum extent possible to comply with Section 409A of the Code in accordance with Section 409A of the
Code and (ii) the Board may amend the Incentive Plan for purposes of complying with Section 409A of the Code. 
 F. No Limit on
Other Compensation Arrangements. Nothing contained in the Incentive Plan shall prevent the Company or any of its Affiliates from adopting or continuing in effect other compensation arrangements, which may, but need not, provide for the award of
Incentive Units, securities and other types of awards, and such arrangements may be either generally applicable or applicable only in specific cases. 

G. No Right to Employment. No award made hereunder shall be construed as giving a Participant the right to be retained in the employ
of, or in any other continuing relationship with, the Company or any of its Affiliates. 

  
 18 

 H. Special Incentive Compensation. By acceptance of an award hereunder, each
Participant shall be deemed to have agreed that such award is special incentive compensation that will not be taken into account, in any manner, as salary, compensation or bonus in determining the amount of any payment under any pension, retirement,
life insurance, disability, severance or other employee benefit plan of the Company or any of its Affiliates. In addition, each beneficiary of a deceased Participant shall be deemed to have agreed that such award will not affect the amount of any
life insurance coverage, if any, provided by any Person on the life of the Participant which is payable to such beneficiary under any life insurance plan covering employees. 

I. Compliance with Laws. The Board may refuse to issue or approve the Transfer of any Incentive Units if it, in its sole discretion,
determines that the issuance or Transfer of such Incentive Units would violate the LLC Agreement, the Securities Act or any applicable law or regulation. Without limiting the generality of the foregoing, no award of an Incentive Unit made hereunder
shall be construed as an offer to sell securities of the Company, and no such offer shall be outstanding, unless and until the Company in its sole discretion has determined that any such offer, if made, would be in compliance with all applicable
securities laws. 
 J. No Trust or Fund Created. Neither the Incentive Plan nor any award made hereunder shall create or be construed
to create a trust or separate fund of any kind, or a fiduciary relationship between the Company, the Board, any Member or any Affiliate, on the one hand, and a Participant or any other Person, on the other hand, except as otherwise expressly
required by applicable Law. 
 K. Severability. If any provision of the Incentive Plan or any award made hereunder is, becomes or is
deemed to be invalid, illegal or unenforceable in any jurisdiction or as to any Person or award, or would disqualify the Incentive Plan or any award under any Law deemed applicable by the Board, such provision shall be construed or deemed amended to
conform to the applicable Laws, or if it cannot be construed or deemed amended without, in the determination of the Board, materially altering the intent of the Incentive Plan or the award, such provision shall be stricken as to such jurisdiction,
Person or award and the remainder of the Incentive Plan and any such award shall remain in full force and effect. 
 L. Amendment to LLC
Agreement. Neither the adoption of the Incentive Plan nor any award made hereunder shall restrict in any way the adoption of any amendment to the LLC Agreement in accordance with the terms of the LLC Agreement. 

M. Conflict Between the Incentive Plan and the LLC Agreement. The Incentive Plan is subject to the LLC Agreement, the terms and
provisions of which are hereby incorporated herein by reference. In the event of a conflict between any term or provision contained herein and a term or provision of the LLC Agreement, the applicable terms and provisions of the LLC Agreement will
govern and prevail. No Participant who holds only Incentive Units shall have any right to receive or review a copy of Schedule A or Schedule B of the LLC Agreement (except for information on Schedule A or Schedule B that relates solely to such
Participant) or obtain other information about the identities of the other Participants or Members or the size or nature of their interests in the Company. 

  
 19 

 N. Headings. Headings are used herein solely as a convenience to facilitate
reference and shall not be deemed in any way material or relevant to the construction or interpretation of the Incentive Plan or any provision thereof. 

O. Interpretations. Unless the express context otherwise requires, with respect the Incentive Plan or any Incentive Unit Agreement:
(i) the terms defined in the singular shall have a comparable meaning when used in the plural, and vice versa; (ii) wherever the word “include,” “includes” or “including” is used, it shall be deemed to be
followed by the words “without limitation;” and (iii) except where otherwise indicated by the context, any masculine term used herein shall also include the feminine. 

P. Governing Law. The validity, construction and effect of the Incentive Plan and any rules and regulations relating to the Incentive
Plan and any Incentive Unit Agreement shall be determined in accordance with the laws of the State of Delaware applicable to agreements made and to be performed entirely within such state. 

Q. DISPUTE RESOLUTION; CONSENT TO JURISDICTION. Each of the parties submits to the exclusive jurisdiction of the courts of the State of
Illinois and agrees that all claims in respect of the action or proceeding may be heard and determined in any such court. Each party also agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court.
Each of the parties waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto. Any party may make
service on any other party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in this Section IX.Q. Nothing in this Section IX.Q, however, shall affect the
right of any party to serve legal process in any other manner permitted by law or at equity. Each party agrees that a final judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any
other manner provided by law or at equity. Each party hereto hereby waives trial by jury in any judicial proceeding involving, directly or indirectly, any matter in any way arising out of or related to this Incentive Agreement or the relationship
established hereunder. Each party acknowledges and agrees that its obligations hereunder are of a special, unique and extraordinary character, that they are reasonably related to the legitimate business interests of the Company, and that a failure
to perform any such obligation or a violation of such obligations will cause irreparable injury to the Company, the amount of which would be impossible to estimate or determine and for which adequate compensation could not be fashioned. Therefore,
the parties agree the Company will be entitled, as a matter of right, and without the need to prove irreparable injury or to post bond, to seek an injunction, restraining order, writ of mandamus or other equitable relief (including specific
performance) from any court of competent jurisdiction, restraining any violation or threatened violation of any term of this Agreement, or requiring compliance with or performance of any obligation hereunder, by the parties and such other persons as
the court will order. 
 R. Term of Plan. The Amended and Restated Incentive Plan shall be effective as of the Closing (the
“Effective Date”). Notwithstanding anything to the contrary herein, if the Purchase Agreement terminates prior to the Closing, the Amended and Restated Incentive Plan shall be void ab initio, and the prior Incentive Plan of the
Company, effective as of December 18, 2015 shall remain in effect. No award shall be made under the Incentive Plan after December 31, 2028. Unless otherwise expressly provided in an applicable Incentive Unit Agreement, the termination of
the Incentive Plan shall not affect the terms of any Incentive Unit awarded hereunder or otherwise subject hereto at the time of termination of the Incentive Plan, and Incentive Unit Agreements then in effect shall continue in effect after
December 31, 2028.

WHEREAS, the Company has adopted the Oak Street Health LLC Equity Incentive Plan (the “Incentive Plan”), which is
incorporated herein by reference and made a part of this Agreement (capitalized terms used and not otherwise defined in this Agreement shall have the meanings set forth for such terms in the Incentive Plan or the Fifth Amended and Restated Limited

provided for herein to the Participant pursuant to the Incentive Plan and the terms and conditions set forth herein; 
 WHEREAS,
simultaneously with the award of the Incentive Units under this Agreement, Participant desires to contribute the Incentive Units to Management LLC in exchange for an identical number of “Incentive Units” of Management LLC (the
“Corresponding Incentive Units”) with the rights, preferences, and privileges as provided in the Limited Liability Company Operating Agreement of Management LLC dated December 12, 2016 (the “Management Operating

 21 

 WHEREAS, Part I of this Agreement describes the terms and conditions of the award of
Incentive Units to Participant by the Company, Part II of this Agreement describes the terms and conditions of the contribution of the Incentive Units by Participant to Management LLC for Corresponding Units and Part III of this
Agreement sets out other terms and conditions and agreements among the parties. 
 NOW THEREFORE, in consideration of the mutual
covenants hereinafter set forth, the parties hereto agree as follows: 
 PART I – Award Agreement 

1. Award of Incentive Units. 

(a) Incentive Units. Subject to the terms and conditions of this Agreement and the Incentive Plan, the Company hereby grants to the
Participant an award of 132,000 Incentive Units (collectively, the “Incentive Units”). 
 (b) Hurdle;
Distributions. The initial aggregate Hurdle Value with respect to the Incentive Units awarded hereby shall be [$696,722,644], as shall be adjusted from time to time in accordance with the Incentive Plan and the LLC Agreement. Distributions in
respect of Incentive Units shall be made to the Participant in accordance with the provisions of the LLC Agreement. For the avoidance of doubt and notwithstanding anything to the contrary herein, or otherwise in the LLC Agreement or in the Plan, in
no event shall the Participant be eligible to receive any distributions in respect of the Incentive Units awarded hereby unless and until the aggregate adjusted Hurdle Value has been achieved. 

2. Vesting. All Incentive Units awarded hereby shall initially be unvested. Fifty percent (50%) of the Incentive Units awarded hereby
shall vest in accordance with Section 2(a) below (the “Service-Vesting Units”), and the balance of the Incentive Units awarded hereby shall vest in accordance with Section 2(b) below (the “Performance-Vesting
Units”). 
 (a) Service-Vesting Units. The Service-Vesting Units shall vest in installments over four (4) years, with
the first 25% vesting on the first anniversary of the Date of Grant and the remaining 75% vesting in equal quarterly installments thereafter (each such date, a “Vesting Date”), subject to the Participant’s continuous employment
with the Company or an Affiliate of the Company through the applicable Vesting Date. Upon or following the consummation of a Sponsors’ Exit (as defined in the Incentive Plan) prior to the final Vesting Date, if the Participant’s employment
is terminated by the Company or its Affiliates other than for Cause, all unvested Service-Vesting Units then outstanding shall become vested, subject to the Participant’s continuous employment with the Company or an Affiliate of the Company
through the date of such Sponsors’ Exit. 
 (b) Performance-Vesting Units. Upon the consummation of a Sponsors’ Exit,
the Performance-Vesting Units shall become 100% vested, subject to the Participant’s continuous employment with the Company or an Affiliate of the Company through the date of such Sponsors’ Exit. 

  
 22 

 3. Effect of Termination of Employment; Company’s Rights to Repurchase Units.

 (a) If the Participant’s employment with the Company and its Affiliates is terminated by either party other than as a result a
termination by the Company without Cause, all then unvested Incentive Units held by the Participant shall be cancelled and forfeited without consideration. 

(b) If the Participant’s employment with the Company and its Affiliates is terminated by the “Company without Cause” or if the
Participant terminates for “Good Reason” (both as defined in the Employment Agreement dated effective as of August 5, 2019), 50% of the Service Vesting Units shall vest upon such termination (inclusive of any such Service Vesting
Units that had previously vested) and any remaining unvested Incentive Units in excess of such amount held by the Participant shall be cancelled and forfeited without consideration. 

(c) If the Participant’s employment is terminated by the Company or an Affiliate for Cause, then all Incentive Units held by the
Participant, whether vested or unvested, shall be cancelled and forfeited without consideration. 
 (d) If the Participant’s employment
with the Company and its Affiliates is terminated for any reason, the vested Incentive Units then held by the Participant shall be subject to cancellation and repurchase by the Company pursuant to this Section 3(d), provided, however, that if
such termination is by the Company without Cause or by the Participant for Good reason, the Company shall not have the right to cancellation and repurchase by the Company pursuant to this Section 3(d) with respect to the Service Vesting Units
that vest pursuant to Section 3(b) above. 
 (i) Upon any termination of Participant’s employment, the Company shall have the
right, but not the obligation (the “Company Call Right”), within 180 days following such termination (the “Call Period”), to make a payment to the Participant in consideration for the cancellation of any one or more
of the vested Incentive Units then held by the Participant (the “Called Units”), such payment to equal the Fair Market Value of such Incentive Units taking into account the applicable Hurdle Value for such Incentive Units (the
“Call Price”). 
 (ii) The Company Call Right may be exercised by the Company or any assignee(s) or designee(s) of the
Company, as applicable, by delivery of written notice (the “Call Notice”) to the Participant within the Call Period. At the closing of the transactions contemplated by the Company Call Right, (i) the Participant shall deliver
certificates, if any, representing the Called Units, duly endorsed for transfer and accompanied by all requisite transfer taxes, if any; (ii) the Called Units shall be free and clear of any Liens (other than those arising hereunder, the LLC
Agreement, securities laws and those attributable to actions by the purchasers thereof) and the Participant shall so represent and warrant; (iii) the Participant shall further represent and warrant that it is the sole beneficial and record
owner of the Called Units; and (iv) the Participant shall provide a limited release of claims with respect to any claims arising out of or related to the Called Units and the Participant’s capacity as an equity holder. For the avoidance of
doubt, all of the Participant’s rights, title and interest in such Incentive Unit shall terminate automatically without any further action required by any Person upon payment of the Call Price for any Incentive Unit. 

  
 23 

 (iii) Notwithstanding the foregoing, if exercise of the Call Right would constitute (or
with notice or lapse of time or both would constitute) an event of default (which remains uncured) under, or would otherwise violate or breach, any financing arrangement of the Company or any of its subsidiaries (a “Financing
Restriction”), or if the Company does not have funds available to effect such repurchase of Incentive Units, the Call Period shall be extended until the earliest date on which such Financing Restriction or unavailability of funds has ceased
and no such event would result from exercise of the Call Right. 
 4. Rights as Holder of Incentive Units. The Participant shall be
the record owner of the Incentive Units granted hereunder unless and until such Units are forfeited or repurchased pursuant to Section 3, or transferred in accordance with Section 6, and as record owner shall be entitled to all rights of a
holder of Incentive Units of the Company; provided, that the Incentive Units shall be subject to the limitations on Transfer set forth in this Agreement, the Incentive Plan and the LLC Agreement. 

5. Participant Representations, Warranties and Acknowledgments. 

(a) No Reliance on the Company. In determining to accept the Incentive Units, the Participant has not relied upon the Company or any of
its Affiliates, or any representative thereof for any advice of any sort, including, but not limited to securities or investment advice, or advice regarding the federal, state or local tax consequences arising from the grant, vesting, holding or
disposition of the Incentive Units (the “Tax Matters”). 
 (b) Acknowledgments. The Participant acknowledges and
agrees that: 
 (i) The Incentive Units cannot be transferred except in very limited circumstances in accordance with the provisions of the
LLC Agreement, the Incentive Plan and this Agreement and at present no market for the Incentive Units exists and it is not anticipated that a market for the Incentive Units will develop in the future. 

(ii) The Incentive Units may be worthless. 

(iii) The Company is treated as a “partnership” for federal and state income tax purposes and, as a result of receiving and holding
the Incentive Units, the Participant will be treated as a “partner” of the Company for federal and state income tax purposes. Further, the Participant acknowledges that the Participant’s status may have adverse consequences to the
Participant with respect to matters in which employees may be treated more favorably than partners, such as entitlement to and the tax treatment of fringe benefits, employee benefit plans, payroll taxes, and possible self-employment tax liability.

 (iv) The Participant will receive an annual Schedule K-1 from the Company requiring that the
Participant report on the Participant’s tax return the Participant’s distributive share of the income, gain, loss, deductions and credits of the Company attributable to the Incentive Units (including any unvested Incentive Units). 

(v) The distributions made to the Participant will not be subject to FICA or other tax withholding. 

  
 24 

 (vi) Ownership of the Incentive Units may result in taxable income to the Participant
without a corresponding cash or in-kind distribution. 
 (vii) The Participant has been advised to
seek and has had an opportunity to seek independent advice regarding the Tax Matters, including the 83(b) Election required by Section 8 hereof. 

(viii) The Company will have no obligation to indemnify or hold the Participants harmless for any claims or liabilities arising from the Tax
Matters. 
 (ix) The Incentive Units will not be registered under the Securities Act of 1933, as amended (the “Securities
Act”) or any applicable state securities laws (collectively, the “Securities Laws”), and they are being issued in reliance upon certain exemptions contained in Securities Laws, including Rule 701 promulgated under the
Securities Act and corresponding state law exemptions, if any, and the representations and warranties of the Participant contained herein are essential to any claim of exemption by the Company under the Securities Laws. 

(x) The Incentive Units are “restricted securities” as that term is defined in Rule 144 promulgated under the Securities Act. 

(xi) The Participant is aware that there is no assurance of an Initial Offering and even in the event of an Initial Offering, any capital
stock which may be distributed by the Company to the Participant cannot be transferred without registration under the Securities Laws unless the Company receives an opinion of counsel acceptable to it (as to both counsel and the opinion) that such
registration is not required. 
 6. TRANSFERABILITY. EXCEPT FOR TRANSFERS TO THE COMPANY OR AS MAY OTHERWISE BE PERMITTED IN THE
LLC AGREEMENT OR THE INCENTIVE PLAN, THE PARTICIPANT MAY TRANSFER, DIRECTLY OR INDIRECTLY, ANY INCENTIVE UNIT OR ANY INTEREST IN ANY INCENTIVE UNIT ONLY WITH THE PRIOR WRITTEN CONSENT OF THE BOARD, WHICH CONSENT SHALL BE WITHHELD OR GRANTED IN THE
SOLE DISCRETION OF THE BOARD. IN ADDITION TO THE RESTRICTIONS ON TRANSFER UNDER THE LLC AGREEMENT, THE INCENTIVE PLAN OR THIS AGREEMENT, THE PARTICIPANT ACKNOWLEDGES THAT THE INCENTIVE UNITS ARE “RESTRICTED SECURITIES” AND MAY ONLY BE
TRANSFERRED IN COMPLIANCE WITH THE REGISTRATION REQUIREMENTS OF THE SECURITIES LAWS OR AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY TO THE EFFECT THAT SUCH REGISTRATION IS NOT REQUIRED. ANY PURPORTED ASSIGNMENT, TRANSFER OR GRANT BY THE
PARTICIPANT, DIRECTLY OR INDIRECTLY, OF ANY INCENTIVE UNIT OR ANY INTEREST IN ANY INCENTIVE UNIT IN CONTRAVENTION OF THE LLC AGREEMENT, THE INCENTIVE PLAN OR THIS AGREEMENT SHALL BE ENTIRELY NULL AND VOID. 

  
 25 

 PART II – Contribution Agreement 

7. Contribution. The Participant hereby contributes, sells, assigns, conveys, transfers and delivers to Management LLC, and Management
LLC accepts from the Participant all of the Incentive Units identified in Section 1(a) in exchange for the issuance by Management LLC to the Participant of an identical number of Corresponding Incentive Units. The Participant irrevocably
constitutes and appoints the Company as the Participant’s true and lawful agent and attorney-in-fact with respect to the Incentive Units, with full power of
substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to transfer ownership of the Incentive Units to Management LLC on the Company’s books and records. 

8. Terms and Conditions of Award Continue. The Participant hereby acknowledges and agrees that (i) the Corresponding Incentive
Units shall be subject to the terms and conditions of Part I of this Agreement and of the Incentive Plan and in particular, the Hurdle Value set forth Section 1(b) of this Agreements will continue to apply to the Corresponding Incentive Units;
and (ii) Part I of this Agreements shall be read as if the “Incentive Units” refers to the Corresponding Incentive Units and as if the “LLC Agreement” refers to the Management Operating Agreement. Either Management LLC or
the Company, acting through this Agreement, the LLC Agreement and the Management Operating Agreement, shall be entitled to enforce any right or remedy of Part I against the Participant. 

9. Member of the Company; Joinder. The Participant hereby (i) agrees and acknowledges that Participant has received and read a copy
of the LLC Agreement and the Management Operating Agreement and (ii) agrees that, if Participant was not a Member of the Management LLC prior to the issuance of the Corresponding Incentive Units hereunder, then by execution of this Agreement,
Participant shall become, effective as of the Date of Grant, a party to the Management Operating Agreement and shall be fully bound by, and subject to, all of the covenants, terms and conditions of the Management Operating Agreement as though an
original party thereto and shall be deemed, and is hereby admitted as, a Member, for all purposes thereof and entitled to all the rights incidental thereto. 

PART III – Other Agreements 
 10.
Profits Interest. The Incentive Units and the Corresponding Incentive Units are intended to constitute a “profits interest” for all U.S. federal income tax purposes. A profits interest is granted in connection with the performance
of services and is a right to receive distributions funded solely by the profits of the Company and Management LLC, respectively, which are generated after the grant. As such, the Board of Management LLC shall, if necessary, limit distributions and
allocations of profits to the Participant so that such distributions and allocations do not exceed the available profits in respect of such Participant’s related profits interest. 

11. Spousal Consent. If married, the Participant has caused the Participant’s spouse to execute and deliver to the Company and
Management LLC the Consent of Spouse in the form attached hereto as Exhibit A. If no Consent of Spouse has been executed and delivered to the Company and Management LLC on the Date of Grant, the Participant represents and warrants that the
Participant is not married and no person has or will have a marital or community property interest in the Incentive Units. If the Participant marries after the Date of Grant, the Participant will cause the Participant’s spouse to execute and
deliver to the Company and Management LLC a Consent of Spouse in the form attached hereto as Exhibit A.

 12. LLC Agreement; Management Operating Agreement. Neither the adoption of the
Incentive Plan nor the grant of any Incentive Units or issuance of Corresponding Incentive Units pursuant to this Agreement shall restrict in any way the adoption of any amendment to the LLC Agreement or Management Operating Agreement in accordance
with its terms. 
 13. Section 83(b) Election. As a condition subsequent to the issuance of the Incentive Units and Corresponding
Incentive Units pursuant to this Agreement, the Participant shall execute and deliver to the Company and the Internal Revenue Service (the “IRS”) a timely, valid election under Section 83(b) of the Code (the “83(b)
Election”) as to each of the Incentive Units and Corresponding Incentive Units. The Participant understands that under Section 83 of the Code, regulations promulgated thereunder, and certain IRS administrative announcements in the
absence of an effective election under Section 83(b) of the Code, the excess of the fair market value of the Incentive Units or Corresponding Incentive Units on the date on which any forfeiture restrictions applicable to such the Incentive
Units or Corresponding Incentive Units lapse over the respective price paid for the Incentive Units or Corresponding Incentive Units (which price is $0) may be reportable as ordinary income at that time. For this purpose, the term “forfeiture
restrictions” means the restrictions on transferability and the vesting conditions imposed under this Agreement. The Participant understands that (i) in making the 83(b) Election as to each of the Incentive Units and Corresponding
Incentive Units, the Participant may be taxed at the time the Incentive Units and Corresponding Incentive Units are acquired hereunder to the extent the fair market value of the Incentive Units and Corresponding Incentive Units exceeds the purchase
price for such Units and (ii) in order to be effective, the 83(b) Election as to each of the Incentive Units and Corresponding Incentive Units must be filed with the IRS within thirty (30) days after the Date of Grant. The Participant
hereby acknowledges that (x) the foregoing description of the tax consequences of the 83(b) Election is not intended to be complete and, among other things, does not describe state, local or non-U.S.
income and other tax consequences or all tax considerations that might be relevant to the Participant in light of the Participant’s circumstances or if the Participant is subject to special tax rules, (y) neither the Company or Management
LLC has provided, and is not hereby providing, the Participant with legal or tax advice regarding the Incentive Units or the Corresponding Incentive Units or the 83(b) Election and has urged the Participant to consult the Participant’s own tax
advisor with respect to the taxation consequences thereof, and (z) neither the Company or Management LLC has advised the Participant to rely on any determination by it or its representatives as to the fair market value specified in the 83(b)
Election and will have no liability to the Participant if the actual fair market value of the Incentive Units or the Corresponding Incentive Units on the Date of Grant exceeds the amount specified in the 83(b) Election. 

14. Notices. Any notice necessary under this Agreement shall be addressed to the Company or Management LLC at the principal executive
office of the Company and to the Participant at the address appearing in the personnel records of the Company or one of its Affiliates or to any party at such other address as such party may hereafter designate in writing to the other parties. Any
such notice shall be deemed effective upon receipt thereof by the addressee.

 15. Incorporation of Incentive Plan and LLC Agreement. By entering into this
Agreement, the Participant agrees and acknowledges that (i) the Participant has received and read a copy of the Incentive Plan, the LLC Agreement and the Management Operating Agreement, (ii) the Incentive Units are subject to this
Agreement, the Incentive Plan and the LLC Agreement, and (iii) the Corresponding Incentive Units are subject to this Agreement, the Incentive Plan and the Management Operating Agreement, the terms and provisions of all of which are hereby
incorporated herein by reference. In the event of a conflict between any term or provision contained herein and a term or provision of the Incentive Plan, the applicable terms and provisions of the Incentive Plan will govern and prevail. In the
event of a conflict between any term or provision contained herein or the Incentive Plan and a term or provision of the Management Operating Agreement, the applicable terms and provisions of the Management Operating Agreement will govern and
prevail. 
 16. CERTAIN SPECIFIC ACKNOWLEDGEMENTS; ENTIRE AGREEMENT. THIS AGREEMENT (TOGETHER WITH THE INCENTIVE PLAN, THE LLC
AGREEMENT AND THE MANAGEMENT OPERATING AGREEMENT) EMBODY THE COMPLETE AGREEMENT AND UNDERSTANDING AMONG THE PARTIES TO THIS AGREEMENT WITH RESPECT TO THE SUBJECT MATTER OF THIS AGREEMENT AND SUPERSEDE AND PREEMPT ANY PRIOR UNDERSTANDINGS, AGREEMENTS
OR REPRESENTATIONS BY OR AMONG THE PARTIES, WRITTEN OR ORAL, WHICH MAY HAVE RELATED TO THE SUBJECT MATTER OF THIS AGREEMENT IN ANY WAY. WITHOUT LIMITING THE PROVISIONS OF SECTION 15, THE PARTICIPANT ACKNOWLEDGES THAT THE CORRESPONDING INCENTIVE
UNITS ARE SUBJECT TO INCENTIVE PLAN, LLC AGREEMENT AND MANAGEMENT OPERATING AGREEMENT PROVISIONS UNDER WHICH (A) IN CERTAIN CIRCUMSTANCES AN ADJUSTMENT MAY BE MADE TO THE NUMBER OF CORRESPONDING INCENTIVE UNITS AND/OR THE APPLICABLE HURDLE
VALUE OF THE CORRESPONDING INCENTIVE UNITS; (B) THE BOARD HAS FULL DISCRETION TO INTERPRET AND ADMINISTER THE INCENTIVE PLAN AND THIS AGREEMENT AND ITS JUDGMENTS ARE FINAL, CONCLUSIVE AND BINDING; AND (C) THE PARTICIPANT MAY BE REQUIRED TO SELL
THE PARTICIPANT’S CORRESPONDING INCENTIVE UNITS OR OTHERWISE PARTICIPATE IN A TRANSACTION WHERE OTHER EQUITY HOLDERS OF THE COMPANY ARE SELLING (A “DRAG-ALONG”). 

17. No Right to Continued Service. Neither the Incentive Plan nor this Agreement shall be construed as giving the Participant the right
to be retained in the employ of, or in any other continuing relationship with, the Company or any of its Affiliates. 
 18. Tax
Withholding. The Participant shall be required to pay to the Company, Management LLC or any Affiliate, and the Company, Management LLC and its Affiliates shall have the right and are hereby authorized to withhold from any payment due or transfer
made under any Corresponding Incentive Unit, under the Incentive Plan or from any other amount owing to a Participant (including in connection with any Transfers), the amount (in cash, securities or other property) of any applicable U.S. federal,
state, local or non-U.S. withholding taxes in respect of an Incentive Unit or any payment or transfer under an Corresponding Incentive Unit or the Incentive Plan and to take such other action as may be

  
 28 

 
necessary in the opinion of the Board to satisfy all obligations for the payment of such taxes. The Company and Management LLC acknowledge that, absent a change in applicable Law, the Participant
intends to value the Incentive Units awarded hereby and Corresponding Incentive Units issued in exchange therefor using the “liquidation value” of such Incentive Units and nd Corresponding Incentive Units, and that consistent with the
intention of the Incentive Units and Corresponding Incentive Units to constitute a “profits interest,” the Participant intends the value of the Incentive Units and Corresponding Incentive Units to be $0 upon grant. The Company, Management
LLC and its Affiliates agree to withhold taxes in a manner consistent with this treatment unless otherwise required by applicable Law. 
 19.
Severability. If any provision of this Agreement is, becomes or is deemed to be invalid, illegal or unenforceable in any jurisdiction or as to any Person, the Incentive Units or the Corresponding Incentive Units, or would disqualify the
Incentive Units or Corresponding Incentive Units under any Law deemed applicable by the Board, such provision shall be construed or deemed amended to conform to the applicable Laws, or if it cannot be construed or deemed amended without, in the
determination of the Board, materially altering the intent of this Agreement, such provision shall be stricken as to such jurisdiction, Person, the Incentive Units or Corresponding Incentive Units and the remainder of this Agreement, the Incentive
Units and Corresponding Incentive Units shall remain in full force and effect. 
 20. Choice of Law; Forum. This Agreement and all
claims and controversies hereunder shall be governed by and construed in accordance with the internal laws of the State of Illinois, without regard to the choice of law provisions thereof. The parties hereto hereby agree and consent to be subject to
the jurisdiction of the U.S. District Court, Northern District of Illinois or the State Court of Illinois, Cook County over any action, suit or proceeding (a “Legal Action”) arising out of or in connection with this Agreement. The
parties hereto irrevocably waive the defense of an inconvenient forum to the maintenance of any such Legal Action. Each of the parties hereto further irrevocably consents to the service of process out of any of the aforementioned courts in any such
Legal Action by the mailing of copies thereof by registered mail, postage prepaid, to such party at its address contained in the records of the Company, Management LLC and its Affiliates, such service of process to be effective upon acknowledgment
of receipt of such registered mail. Nothing in this Section shall affect the right of any party hereto to serve legal process in any other manner permitted by law. This provision may be filed with any court as written evidence of the knowing and
voluntary irrevocable agreement between the parties to waive any objections to venue or to convenience of forum. 
 21. WAIVER OF JURY
TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT (WHETHER BASED ON
CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT SUCH PARTY AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.
