Therefore, in the event of any ambiguity or conflict in this Agreement or any of the exhibits or schedules attached hereto, it is the intent of the Parties that such ambiguity or conflict be resolved in such a manner that gives effect to the steps reflected in Exhibit G attached hereto, including the final legal entity structure of OSH Inc. and its subsidiaries set forth on Schedule II.

3. Waiver of Requirements. Each of the Parties hereby irrevocably waives any claim that the execution or consummation of any of the transactions effected pursuant to this Agreement violate or are prevented by any provision of such Party’s governing documents, including any limited liability company agreement, operating agreement, bylaws, or other similar governing document (including any provision that may purport to require any member or owner of such Party to offer such Party’s securities to any other person before transferring ownership of such securities).

4. Exhibits. Each of the exhibits hereto, upon execution and/or filing with any relevant filing or regulatory authority, shall be appended to this Agreement as the final and definitive forms of such Exhibit.

5. Adjustments. In the event that OSH Inc. reasonably determines following the date hereof that any of the dollar amounts or figures set forth herein should be adjusted, amended or revised in order to account for or reflect the finally determined and agreed upon allocations or values of the cash or equity contributions and/or transactions described herein, this Agreement and any of the exhibits or schedules hereto may be so amended, modified or revised by OSH Inc. with the consent or approval of GA Interholdco and Newlight Harbour Point SPV LLC (which consent or approval may be given by email or otherwise in writing by any party authorized to act on behalf of GA Interholdco and Newlight Harbour Point SPV LLC, respectively), it being the intent of the Parties that any such amendments, modifications or revisions shall be effective as of the date hereof.

6. Remedies.

9. Governing Law. All issues and questions concerning the construction, validity, interpretation and enforceability of this Agreement and the Schedules and the Exhibits hereto shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

10. MUTUAL WAIVER OF JURY TRIAL. THE PARTIES HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN STATUTE, CONTRACT, TORT OR OTHERWISE. THE PARTIES AGREE THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE TRIAL BY JURY AND THAT ANY ACTION OR PROCEEDING WHATSOEVER BETWEEN THEM RELATING TO THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY SHALL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

11. Construction. The language used in this Agreement shall be deemed to be the language chosen by the Parties to express their mutual intent, and no rule of strict construction shall be applied against any such Party. The headings of the sections and paragraphs of this Agreement have been inserted for convenience of reference only and shall in no way restrict or otherwise modify any of the terms or provisions hereof. Each defined term used in this Agreement shall have a comparable meaning when used in its plural or singular form.

12. Entire Agreement.

13. Amendments and Waiver. Except as set forth in Section 5 or as necessary to give effect to Section 2, this Agreement or any term hereof may be changed, waived, discharged or terminated only by an agreement in writing signed by the Party against which such change, waiver, discharge or termination is sought to be enforced.

14. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

To that end, each Party shall, in its sole expense, execute and deliver such further agreements, certificates, forms, elections, filings and instruments of conveyance and transfer and take such additional action as any other Party may reasonably request to effect, consummate, confirm or evidence the transactions contemplated herein.

16. Counterparts; Electronic Delivery. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments hereto or thereto, may be executed in one or more counterparts, all of which shall constitute one and the same instrument. Any such counterpart, to the extent delivered by means of a facsimile machine or by .pdf, .tif, .gif, .peg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”) shall be treated in all manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any Party, each other Party or thereto shall re-execute the original form of this Agreement (i.e. the form fully executed by all of the Parties) and deliver such form to all other Parties. No Party shall raise the use of Electronic Delivery to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of Electronic Delivery as a defense to the formation of a contract, and each such Party forever waives any such defense, except to the extent such defense relates to lack of authenticity.

17. Place of Execution. Notwithstanding anything herein to the contrary and unless otherwise required by applicable law, this Agreement and all attachments hereto shall, for all purposes, be deemed to have been executed in Chicago, Illinois on the date hereof.

CONTRIBUTION AND EXCHANGE AGREEMENT

See attached.

CONTRIBUTION AND EXCHANGE AGREEMENT

THIS CONTRIBUTION AND EXCHANGE AGREEMENT (this “Agreement”) is made as of August 10, 2020, by and among Oak Street Health, Inc., a Delaware corporation (“OSH Inc.”), General Atlantic (OSH) Interholdco L.P, a Delaware limited partnership (“GA Interholdco”), General Atlantic (OSH) LLC, a Delaware limited liability company (“GA Blocker”), Quantum Strategic Partners Ltd., a Cayman Islands exempted company (“QSP” and, together with GA Interholdco, the “Contributing Investors”), and QSP OSH Holdings LLC, a Delaware limited liability company (“Newlight Blocker” and, together with GA Blocker, the “Sponsor Blockers”). Capitalized terms used but not otherwise defined herein shall have the meaning set forth in Exhibit H to the Master Structuring Agreement dated as of the date hereof.

WHEREAS, GA Interholdco owns all of the issued and outstanding common units and certain debt instruments in GA Blocker, as set forth on Schedule I hereto (all such common units and such debt instruments in GA Blocker, the “GA Blocker Contributed Interests”); and

WHEREAS, QSP owns all of the issued and outstanding common units, as set forth on Schedule I hereto, in Newlight Blocker (all such common units in Newlight Blocker, the “Newlight Blocker Contributed Interests” and, together with the GA Blocker Contributed Interests, the “Contributed Interests”).

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties, covenants and agreements set forth herein, intending to be legally bound hereby, the parties hereto agree as follows:

1. Contribution of Contributed Interests and Issuance of Exchange Shares.

(a) Each of GA Interholdco and QSP shall contribute, transfer and assign (or cause to be contributed, transferred and assigned) to OSH Inc. all of such Contributing Investor’s right, title and interests in all of the Contributed Interests held by such Contributing Investor and in exchange for such Contributed Interests, OSH Inc. shall issue to such Contributing Investor the number of Exchange Shares set forth opposite such Contributing Investor’s name on Schedule I hereto, free and clear of any lien, charge, pledge, security interest, encumbrance, right of first refusal, preemptive right or other restriction.

(b) The issuance of the Exchange Shares to each of the Contributing Investors hereunder is intended to be exempt from registration under the Securities Act pursuant to Rule 506 of Regulation D and/or Section 4(a)(2) of the Securities Act.

(c) The Exchange Shares will continue to be Exchange Shares for purposes of this Agreement in the hands of any holder other than a Contributing Investor (except for OSH Inc. or its subsidiaries and except for transferees in a public offering), and except as otherwise provided herein, each such other holder of the Exchange Shares will succeed to all rights and obligations attributable to such Contributing Investor as a holder of the Exchange Shares pursuant to this Agreement. The Exchange Shares will also include units of OSH Inc.’s equity interests issued with respect to the Exchange Shares by way of a split, dividend, distribution or other recapitalization.

2. Representations and Warranties of OSH Inc. In connection with the transactions contemplated hereby, OSH Inc. represents and warrants to each Contributing Investor that:

(a) The execution, delivery and performance of this Agreement has been duly authorized by OSH Inc. and this Agreement constitutes a valid and binding obligation of OSH Inc., enforceable in

accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, receivership and similar laws affecting the enforcement of creditors’ rights generally and general equitable principles. The execution, delivery and performance of this Agreement, the consummation of the transactions contemplated hereby and the receipt of the Contributed Interests by OSH Inc. do not and will not (i) conflict with or result in a breach of the terms, conditions or provisions of, (ii) constitute a default under, (iii) result in the creation of any lien, security interest, charge or lien upon such Contributed Interests pursuant to, (iv) give any third party the right to modify, terminate or accelerate any obligation under, (v) result in a violation of or (vi) require any authorization, consent, approval, exemption or other action by or notice to any governmental authority pursuant to, any law to which OSH Inc. is subject, or any agreement, instrument, order, judgment or decree to which OSH Inc. is a party or by which OSH Inc. is bound.

(b) The Exchange Shares have been duly authorized and are validly issued, fully paid and non-assessable.

3. Representations and Warranties of each Contributing Investor.

(a) In connection with the transactions contemplated hereby, each Contributing Investor represents and warrants to OSH Inc. that:

(i) The execution, delivery and performance of this Agreement has been duly authorized by such Contributing Investor and this Agreement constitutes a valid and binding obligation of such Contributing Investor, enforceable in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, receivership and similar laws affecting the enforcement of creditors’ rights generally and general equitable principles. The execution, delivery, and performance of this Agreement, the consummation of the transactions contemplated hereby, and the delivery of the Contributed Interests to OSH Inc. by such Contributing Investor do not and will not (i) conflict with or result in a breach of the terms, conditions or provisions of, (ii) constitute a default under, (iii) result in the creation of any lien, security interest, charge or lien upon such Contributed Interests pursuant to, (iv) give any third party the right to modify, terminate or accelerate any obligation under, (v) result in a violation of or (vi) require any authorization, consent, approval, exemption or other action by or notice to any governmental authority pursuant to, any law to which such Contributing Investor is subject, or any agreement, instrument, order, judgment or decree to which such Contributing Investor is a party or by which such Contributing Investor is bound.

(ii) The Exchange Shares to be acquired by such Contributing Investor pursuant to this Agreement will be acquired for such Contributing Investor’s own account and not with a view to, or intention of, distribution thereof in violation of the Securities Act, or any applicable state securities laws, and the Exchange Shares will not be disposed of in contravention of the Securities Act or any applicable state securities laws.

(iii) Such Contributing Investor is an “accredited investor” within the meaning of Rule 501 of Regulation D of the Securities and Exchange Commission, is sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Exchange Shares.

(iv) Such Contributing Investor is able to bear the economic risk of such Contributing Investor’s investment in the Exchange Shares for an indefinite period of time because the Exchange Shares have not been registered under the Securities Act and, therefore, cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available.

(b) In connection with the transactions contemplated hereby, each GA Interholdco represents and warrants to OSH Inc. that prior to the contribution of Contributed Interests as contemplated in Section 1 hereof, GA Interholdco has capitalized GA Blocker in order to remove a portion of the outstanding shareholder debt. Any outstanding shareholder debt held by the GA Blocker which shall not be capitalized pursuant to this Section 3(b) is set forth in Schedule II hereto, and each such debt instrument has a term to maturity of less than five years.

4. Treatment of Uncapitalized GA Blocker Debt Instruments. OSH Inc. shall (i) treat each debt instrument identified on Schedule II hereto as indebtedness of GA Blocker for federal and applicable state and local income tax purposes and (ii) file all applicable Tax Returns consistent with such treatment unless otherwise required by a change in applicable Law.

5. Transferability. Each of the Contributing Investors acknowledges that the Exchange Shares are subject to certain transfer restrictions.

6. Fractional Units. Notwithstanding anything to the contrary in this Agreement, no fractional Exchange Shares shall be issued upon the exchange or conversion of any Contributed Interests and in lieu of the issuance of any such fractional Exchange Shares, the aggregate number of Exchange Shares to be issued to the holder of such Contributed Interests shall be rounded up to the first whole Exchange Share. The parties hereto acknowledge that such rounding in lieu of issuing fractional Exchange Shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional Exchange Shares.

7. Notices. Any notice, request, demand, claim or other communication required or permitted to be delivered, given or otherwise provided under this Agreement must be in writing and must be delivered personally, delivered by nationally recognized overnight courier service or sent by email. Any such notice, request, demand, claim or other communication shall be deemed to have been delivered and given (a) when delivered, if delivered personally, (b) the business day after it is deposited with such nationally recognized overnight courier service, if sent for overnight delivery by a nationally recognized overnight courier service or (c) the day of sending, if sent by email prior to 5:00 p.m. (Eastern time) on any Business Day or the next succeeding Business Day if sent by email after 5:00 p.m. (Eastern time) on any Business Day or on any day other than a Business Day:

Immediately following the consummation of the Merger, all issued and outstanding equity interests of the Surviving Company shall be held by OSH Inc. or its subsidiaries.

5. Managers and Officers. The members of the board of directors and the officers of OSH LLC holding office immediately prior to the Effective Time shall be the initial members of the board of directors and the officers, respectively (holding the same positions as each held with OSH LLC immediately prior to the Effective Time), of the Surviving Company and shall hold such office from the Effective Time until their respective successors are duly elected or appointed and qualified in the manner provided in the certificate of formation and the limited liability company agreement of the Surviving Company or their earlier death, incapacitation, retirement, resignation or removal.

6. Surviving Company.

(a) Name. The name of the Surviving Company shall be “Oak Street Health, LLC”.

(b) Rights and Obligations. The Merger shall have the effects of applicable law, including, without limitation, the applicable provisions of Applicable Law.

7. Effect of Merger on Outstanding Units. At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof:

(b) Founder Units of OSH LLC. Each Founder Unit of OSH LLC issued and outstanding immediately prior to the Effective Time shall be cancelled as of the Effective Time.

(c) Investor Units I of OSH LLC. Each Investor Unit I of OSH LLC issued and outstanding immediately prior to the Effective Time shall be cancelled as of the Effective Time and be converted at the Effective Time into a right to receive the number of shares of Common Stock of OSH Inc. set forth on Schedule I hereto. Such shares of Common Stock shall be deemed issued as of the Effective Time.

(d) Investor Units II of OSH LLC. Each Investor Unit II of OSH LLC issued and outstanding immediately prior to the Effective Time shall be cancelled as of the Effective Time and be converted at the Effective Time into a right to receive the number of shares of Common Stock of OSH Inc. set forth on Schedule I hereto. Such shares of Common Stock shall be deemed issued as of the Effective Time.

(e) Investor Units III of OSH LLC. Each Investor Unit III of OSH LLC issued and outstanding immediately prior to the Effective Time shall be cancelled as of the Effective Time and, with respect to Investor Units III that do not have a corresponding Investor Unit III held at OSH Management Holdings, LLC, shall be converted at the Effective Time into a right to receive the number of shares of Common Stock of OSH Inc. set forth on Schedule I hereto.

Notwithstanding the foregoing, any unit or interest of OSH LLC that is held directly by (or indirectly through a wholly-owned subsidiary of) OSH Inc. at the Effective Time of the Merger contemplated by this Agreement (including those units or interests held by any entity all of the interests of which are to be contributed to OSH Inc. prior to the Merger contemplated by this Agreement and those units or interests held by OSH Management Holdings, LLC) shall remain outstanding following the Merger contemplated by this Agreement and will not be converted into shares of OSH Inc. in connection with the Merger contemplated by this Agreement.

8. Fractional Units. Notwithstanding anything to the contrary in this Agreement, no fractional shares or equity awards of OSH Inc. shall be issued upon the exchange or conversion of any Investor Units I, Investor Units II, Investor Units III or Incentive Units of OSH LLC and in lieu of the issuance of any such fractional shares or equity awards of OSH Inc., the aggregate number of shares to be issued to the holder of such Investor Units I, Investor Units II, Investor Units III or Incentive Units of OSH LLC shall be rounded up to the first whole share or equity award, as applicable. The parties hereto acknowledge that such rounding in lieu of issuing fractional shares or equity awards is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares or equity awards.

9. Adjustments. In the event that OSH Inc. determines following the date hereof that any unit, share or award amounts or corresponding numbers or figures set forth herein should be adjusted, amended or revised in order to account for or reflect the finally determined and agreed upon allocation or exchange of units, equity securities or equity appreciation rights, such numbers or figure set forth herein may be so amended, modified or revised by OSH Inc. with the consent or approval of each of General Atlantic (OSH) Interholdco L.P. and Newlight Harbour Point SPV LLC (which consent or approval may be given by email or otherwise in writing by any party authorized to act on behalf of General Atlantic (OSH) Interholdco L.P. and Newlight Harbour Point SPV LLC, respectively) in order to reflect such final allocation or exchange numbers, it being the intent of the parties hereto that any such amendments, modifications or revisions shall be effective as of the date hereof.

12. Miscellaneous.

(b) Governing Law. All issues and questions concerning the construction, validity, interpretation and enforceability of this Agreement and the Schedules hereto shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. Each of the parties to this Agreement irrevocably agrees that any legal action or proceeding arising out of or relating to this Agreement brought by any other party or its successors or assigns shall be brought and determined only in the Delaware Chancery Court and any state court sitting in the State of Delaware to which an appeal from the Delaware Chancery Court may be validly taken, and each of the parties hereby irrevocably submits to the exclusive jurisdiction of the aforesaid courts for itself and with respect to its property, generally and unconditionally, with regard to any such action or proceeding arising out of or relating to this Agreement and the transactions contemplated hereby.

(c) Counterparts; Facsimile and Electronic Signatures. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments hereto or thereto, may be executed in one or more counterparts, all of which shall constitute one and the same instrument. Any such counterpart, to the extent delivered by means of a facsimile machine or by .pdf, .tif,.gif, .peg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”) shall be treated in all manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person.

Each of the parties agrees not to commence any action, suit or proceeding relating thereto except in the courts described above in Delaware, other than actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court in Delaware as described herein, and no party will file a motion to dismiss any action filed in a state or federal court in the State of Delaware, on any jurisdictional or venue-related grounds, including the doctrine of forum non conveniens. Process in any action or proceeding referred to in this Section 11(b) may be served on any Party anywhere in the world.

(c) Counterparts; Facsimile and Electronic Signatures. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments hereto or thereto, may be executed in one or more counterparts, all of which shall constitute one and the same instrument. Any such counterpart, to the extent delivered by means of a facsimile machine or by .pdf, .tif, .gif, .peg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”) shall be treated in all manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto, each other party or thereto shall re-execute the original form of this Agreement (i.e. the form fully executed by all of the parties) and deliver such form to all other parties. No party shall raise the use of Electronic Delivery to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of Electronic Delivery as a defense to the formation of a contract, and each such party forever waives any such defense, except to the extent such defense relates to lack of authenticity.
