 Exhibit 10.5 

INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (this “Agreement”) is made and entered into as of
                , 2020 between Oak Street Health, Inc., a Delaware corporation (the “Company”), and [ ] (“Indemnitee”). 

WHEREAS, highly competent persons have become more reluctant to serve corporations as directors or officers or in other capacities unless they
are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation; 

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in order to attract and retain qualified
individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such insurance has been
a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher
premiums and with more exclusions. At the same time, directors, officers and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other
things, matters that traditionally would have been brought only against the corporation or business enterprise itself. The Bylaws of the Company (as amended or restated, the “Bylaws”) require indemnification of the officers and
directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (“DGCL”). The Bylaws and the DGCL expressly provide that the indemnification provisions
set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the Board, officers of the Company and other persons with respect to indemnification; 

WHEREAS, the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and retaining such
persons; 
 WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the
best interests of the Company and its stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

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

WHEREAS, this Agreement is a supplement to and in furtherance of the Bylaws and any resolutions adopted pursuant thereto, and shall not be
deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; [and] 
 WHEREAS, Indemnitee may not be
willing to serve or continue to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve or continue to serve in such capacity; Indemnitee is willing to serve, continue to serve and take on additional
service for or on behalf of the Company on the condition that Indemnitee be so indemnified[; and] 












 [WHEREAS, Indemnitee has certain rights to indemnification and/or insurance provided by
General Atlantic LLC (“General Atlantic”) or affiliates of General Atlantic which Indemnitee and General Atlantic intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the
Company’s acknowledgment of and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve on the Board].1 

[WHEREAS, Indemnitee has certain rights to indemnification and/or insurance provided by Newlight Partners LP (“Newlight”) or
affiliates of Newlight which Indemnitee and Newlight intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s acknowledgement of and agreement to the foregoing being a
material condition to Indemnitee’s willingness to serve on the
 Board.]2
 NOW,
THEREFORE, in consideration of Indemnitee’s agreement to serve as a director or officer from and after the date hereof, the parties hereto agree as follows: 

1. Indemnity of Indemnitee. Subject to the provisions of Section 9, the Company hereby agrees to hold
harmless and indemnify Indemnitee to the fullest extent permitted by law, as such may be amended from time to time, if Indemnitee was or is, or is threatened to be made, a party to, or otherwise becomes involved in, any Proceeding (as hereinafter
defined) by reason of Indemnitee’s Corporate Status (as hereinafter defined). In furtherance of the foregoing indemnification, and without limiting the generality thereof: 

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

(b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this
Section 1(b) if, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to this
Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee, or on Indemnitee’s behalf, in connection with such Proceeding if Indemnitee acted in good faith and in
a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so provides, no indemnification

against such Expenses shall be made in respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company
unless and only to the extent that the court in which the Proceeding was brought shall determine that Indemnitee is fairly and reasonably entitled to indemnification. 

(c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provision of this Agreement,
to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a party to or participant in and is successful, on the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter therein, in whole or in
part, Indemnitee shall be indemnified to the maximum extent permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. If
Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses
actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section 1(c) and without limitation, the termination
of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

(d) [Indemnification of Nominating Member. If (i) Indemnitee is or was affiliated with one or more investment partnerships that
has invested directly or indirectly in the Company (a “Nominating Member”), (ii) the Nominating Member is, or is threatened to be made, a party to or a participant in any Proceeding, and (iii) the Nominating Member’s
involvement in the Proceeding results from any claim based on the Indemnitee’s service to the Company as a director or other fiduciary of the Company, the Nominating Member will be entitled to indemnification hereunder for Expenses to the same
extent as Indemnitee and advancement of Expenses shall apply to any such indemnification of Nominating Member. The Company and Indemnitee agree that each Nominating Member is an express third party beneficiary of the terms of this
Section 1(d).]3 
 2. Additional Indemnity. In
addition to, and without regard to any limitations on, the indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does, to the fullest extent permitted by applicable law, indemnify and
hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf if, by reason of Indemnitee’s Corporate Status, Indemnitee
is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of the Company). The only limitation that shall exist upon the Company’s obligations pursuant to this Agreement, other than
those set forth in Section 9 hereof, shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in
Sections 6 and 7 hereof) to be unlawful.

 3. Contribution. 

(a) Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any threatened, pending
or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), to the fullest extent permitted by applicable law, the Company shall pay, in the first
instance, the entire amount of any judgment or settlement of such action, suit or proceeding without requiring Indemnitee to contribute to such payment and the Company hereby waives and relinquishes any right of contribution it may have against
Indemnitee. The Company shall not, without the Indemnitee’s prior written consent, enter into any such settlement of any action, suit or proceeding (in whole or in part) unless such settlement (i) provides for a full and final release of
all claims asserted against Indemnitee and (ii) does not impose any Expense, judgment, fine, penalty or limitation on Indemnitee. 

(b) Without diminishing or impairing the obligations of the Company set forth in the preceding subparagraph, if, for any reason, Indemnitee
shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit
or proceeding), to the fullest extent permitted by applicable law, the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in
proportion to the relative benefits received by the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one
hand, and Indemnitee, on the other hand, from the transaction or events from which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary
to conform to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action,
suit or proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the transaction or events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which the law
may require to be considered. The relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the
one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or
secondary and the degree to which their conduct is active or passive. 
 (c) To the fullest extent permitted by applicable law, the Company
hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution which may be brought by officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee. 

(d) To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to
Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for
Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in 

  
 4 













 
light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s)
giving cause to such Proceeding, and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 

4. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the fullest extent permitted by
applicable law and to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness, is made (or asked) to respond to discovery requests, or is otherwise asked to participate, in any Proceeding to which Indemnitee is not
a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

5. Advancement of Expenses. Notwithstanding any other provision of this Agreement (other than Section 9), the
Company shall advance, to the extent not prohibited by law, all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding (or part of any Proceeding) not initiated by Indemnitee or any Proceeding initiated by Indemnitee with
the prior approval of the Board as provided in Section 9(d), within thirty (30) days after the receipt by the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time,
whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee. Any advances pursuant to this Section 5 shall be unsecured and
interest free. In accordance with Section 7(d) of this Agreement, advances shall include any and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred
preparing and forwarding statements to the Company to support the advances claimed. This Section 5 shall not apply to claim by Indemnitee for expenses in a matter for which indemnity and advancement of expenses is excluded
pursuant to Section 9. 
 6. Procedures and Presumptions for Determination of Entitlement to
Indemnification. It is the intent of this Agreement to secure for Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly, the parties agree that the
following procedures and presumptions shall apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement: 

(a) To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith
such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of
such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any failure of Indemnitee to provide such a request to the Company, or to provide such a request in a
timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless, and to the extent that, such failure actually and materially prejudices the interests of the Company. 

  
 5 













 (b) Upon written request by Indemnitee for indemnification pursuant to the first sentence
of Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the Board: (1) by
a majority vote of the Disinterested Directors (as hereinafter defined), even though less than a quorum; (2) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum;
(3) if there are no Disinterested Directors, or if the Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee; or (4) if so directed by the Board, by
the stockholders of the Company; provided, however, that if a Change in Control has occurred, the determination with respect to Indemnitee’s entitlement to indemnification shall be made by Independent Counsel. For purposes hereof,
Disinterested Directors are those members of the Board who are not parties to the action, suit or proceeding in respect of which indemnification is sought by Indemnitee. 

(c) In the event the determination of entitlement to indemnification is to be made by Independent Counsel, the Independent Counsel shall be
selected as provided in this Section 6(c). If a Change in Control has not occurred, the Independent Counsel shall be selected by the Board, and the Company shall give written notice to the Indemnitee advising Indemnitee of
the identity of the Independent Counsel so selected. Indemnitee may, within 10 days after such written notice of selection shall have been given, deliver to the Company a written objection to such selection; provided, however, that
such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 12 of this Agreement, and the objection
shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the Person so selected shall act as Independent Counsel. If a written objection is made and substantiated, the Independent Counsel selected
may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If a Change in Control has occurred, the Independent Counsel shall be selected by the Indemnitee
(unless the Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and approved by the Board within 20 days after notification by Indemnitee. If (i) an Independent Counsel is to
make the determination of entitlement pursuant to this Section 6, and (ii) within 20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a)
hereof, no Independent Counsel shall have been selected (including as a result of an objection to the selected Independent Counsel), either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware or other court of
competent jurisdiction for resolution of any objection which shall have been made by Indemnitee to the Company’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a Person selected by the court or by such
other Person as the court shall designate, and the Person with respect to whom all objections are so resolved or the Person so appointed shall act as Independent Counsel under Section 6(b) hereof. The Company shall pay any
and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 6(b) hereof, and the Company shall pay all reasonable fees and expenses incident
to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed. 

(d) In making a determination with respect to entitlement to indemnification hereunder, the Person making such determination shall to
the fullest extent permitted by law presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof to overcome such presumption. Neither the failure of the
Company (including by its directors or independent legal 

  
 6 













 
counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the
applicable standard of conduct, nor an actual determination by the Company (including by its directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption
that Indemnitee has not met the applicable standard of conduct. 
 (e) Indemnitee shall be deemed to have acted in good faith if
Indemnitee’s action is based on the records or books of account of the Enterprise (as hereinafter defined), including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their
duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the
Enterprise. In addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement.
Whether or not the foregoing provisions of this Section 6(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner Indemnitee reasonably believed to be in or
not opposed to the best interests of the Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

(f) If the Person empowered or selected under this Section 6 to determine whether Indemnitee is entitled to
indemnification shall not have made a determination within thirty (30) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall to the fullest extent permitted by law be
deemed to have been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially
misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 30-day period may be extended
for a reasonable time, not to exceed an additional fifteen (15) days, if the Person making such determination with respect to entitlement to indemnification in good faith requires such additional time to obtain or evaluate documentation and/or
information relating thereto; and provided, further, that the foregoing provisions of this Section 6(f) shall not apply if the determination of entitlement to indemnification is to be made by the stockholders
pursuant to Section 6(b) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination, the Board or the Disinterested Directors, if appropriate, resolve
to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of
stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made
thereat. 
 (g) Indemnitee shall cooperate with the Person making such determination with respect to Indemnitee’s entitlement
to indemnification, including providing to such Person upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee


  
 7 













 
and reasonably necessary to such determination. Any costs or expenses (including reasonable attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the Person making
such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 

(h) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to
avoid expense, delay, distraction, disruption and uncertainty. In the event that any action, claim or proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without
limitation, settlement of such action, claim or proceeding with or without payment of money or other consideration) it shall to the fullest extent permitted by law be presumed that Indemnitee has been successful on the merits or otherwise in such
action, suit or proceeding. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

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

7. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is
not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made
pursuant to Section 6(b) of this Agreement within thirty (30) days after receipt by the Company of the request for indemnification or (iv) payment of indemnification is not made within ten (10) days after a
determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an
appropriate court of the State of Delaware, or in any other court of competent jurisdiction, of Indemnitee’s entitlement to such indemnification, contribution or advancement of Expenses. Alternatively, Indemnitee, at Indemnitee’s option,
may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award
in arbitration. 
 (b) In the event that a determination shall have been made pursuant to Section 6(b) of this
Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial, or arbitration, on the merits,
and Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b). In any judicial proceeding or arbitration commenced pursuant to this Section 7, Indemnitee shall be
presumed to be entitled to 

  
 8 













 
indemnification under this Agreement and the Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be, and the Company
may not refer to or introduce into evidence any determination pursuant to Section 6(b) of this Agreement adverse to Indemnitee for any purpose other than to establish its compliance with the terms of this Agreement. If
Indemnitee commences a judicial proceeding or arbitration pursuant to this Section 7, Indemnitee shall not be required to reimburse the Company for any advances pursuant to Section 5 until a final
determination is made with respect to Indemnitee’s entitlement to indemnification (as to which all rights of appeal have been exhausted or lapsed). 

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

(d) In the event that Indemnitee, pursuant to this Section 7, incurs costs, in a judicial or arbitration proceeding
or otherwise, attempting to enforce Indemnitee’s rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the Company, the Company
shall pay on Indemnitee’s behalf, in advance, any and all expenses (of the types described in the definition of Expenses in Section 12 of this Agreement) actually and reasonably incurred by Indemnitee in such efforts,
regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery, to the fullest extent permitted by applicable law. It is the intent of the Company that, to the fullest
extent permitted by applicable law, Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the
cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee hereunder. 
 (e) The Company
shall, to the fullest extent not prohibited by law, be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 7 that the procedures and presumptions of this Agreement are not
valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement. 

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

(a) The rights of indemnification and to receive advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any
other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation of the Company (as amended or restated, the “Charter”), the Bylaws, any agreement, a vote of


  
 9 













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

(b) The Company shall, if commercially reasonable, obtain and maintain in effect during the entire period for which the Company is obligated
to indemnify Indemnitee under this Agreement, one or more policies of insurance with reputable insurance companies to provide the directors and officers of the Company with coverage for losses from wrongful acts and omissions and to ensure the
Company’s performance of its indemnification obligations under this Agreement. Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such officer or
director under such policy or policies. In all such insurance policies, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee with the same rights and benefits as are accorded to the most favorably insured of the
Company’s directors and officers. At the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set
forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such
policies. 
 (c) [The Company hereby acknowledges that Indemnitee has certain rights to indemnification, advancement of expenses and/or
insurance provided by [General Atlantic][Newlight] and certain affiliates that, directly or indirectly, (i) are controlled by, (ii) control or (iii) are under common control with, [General Atlantic][Newlight] (collectively, the
“Fund Indemnitors”). With respect to any amounts that are subject to indemnity under this Agreement and also subject to an indemnity obligation owed by Fund Indemnitors, the Company hereby agrees (i) that, as compared to the
Fund Indemnitors, it is the indemnitor of first resort with respect to any rights to indemnification provided to Indemnitee herein (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance expenses or to
provide indemnification for the same expenses or liabilities incurred by Indemnitee is secondary), (ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all
Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Charter or Bylaws of the Company (or any other agreement between the Company and Indemnitee),
without regard to any rights Indemnitee may have against the Fund Indemnitors, and (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution,
subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund 

  
 10 













 
Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a
right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Fund Indemnitors are express third party
beneficiaries of the terms of this Section 8(c).] 
 (d) [Except as provided in
Section 8(c) above,] in the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee [(other than against the Fund
Indemnitors)], who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

(e) [Except as provided in Section 8(c) above,] the Company shall not be liable under this Agreement to make any
payment of amounts otherwise indemnifiable (or for which advancement of Expenses is provided) hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise.

 (f) [Except as provided in Section 8(c) above,] the Company’s obligation to indemnify or advance Expenses
hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any
amount Indemnitee has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. 

9. Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company shall not be obligated under
this Agreement to make any indemnity or advancement of expenses in connection with any claim made against Indemnitee: 
 (a) for which
payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; [provided,
that the foregoing shall not affect the rights of Indemnitee or the Fund Indemnitors set forth in Section 8(c) above;] or 

(b) for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the
meaning of Section 16(b) of the Exchange Act (as hereinafter defined), or similar provisions of state statutory law or common law; or 

(c) for reimbursement to the Company of any bonus or other incentive-based or equity-based compensation or of any profits realized by
Indemnitee from the sale of securities of the Company, in each case as required under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act
of 2002 (the “Sarbanes-Oxley Act”) or Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act in connection with an accounting restatement of the Company or the payment to the Company of profits arising from the
purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act); 

  
 11 













 (d) in connection with any Proceeding (or any part of any Proceeding) initiated by
Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Company has joined in or the Board authorized the
Proceeding (or any part of any Proceeding) prior to its initiation, (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law, or (iii) the Proceeding is one to
enforce Indemnitee’s rights under this Agreement or; 
 (e)    any reimbursement of the Company by Indemnitee of
any compensation pursuant to any compensation recoupment or clawback policy adopted by the Board or the compensation committee of the Board, including but not limited to any such policy adopted to comply with stock exchange listing requirements
implementing Section 10D of the Exchange Act. 
 10. Non-Disclosure of Payments.
Except as expressly required by the securities laws of the United States of America, neither party shall disclose any payments under this Agreement unless prior approval of the other party is obtained. If any payment information must be disclosed,
the Company shall afford the Indemnitee an opportunity to review all such disclosures and, if requested, to explain in such statement any mitigating circumstances regarding the events to be reported. 

11. Duration of Agreement. All agreements and obligations of the Company contained herein shall continue until and terminate upon the
later of (i) twenty (20) years after the date that Indemnitee shall have ceased to serve as a director or officer of the Company or a director, officer, trustee, partner, managing member, fiduciary, employee or agent of any other corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise which Indemnitee served at the request of the Company, and (ii) one (1) year after the final termination of any Proceeding (including any rights of appeal thereto) in
respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any Proceeding commenced by Indemnitee pursuant to Section 7 of this Agreement relating thereto (including any
rights of appeal of any Section 7 Proceeding). Termination of this Agreement shall not adversely affect any right or protection hereunder of any Indemnitee in respect of any Proceeding (regardless of when such Proceeding is
first threatened, commenced or completed) arising out of, or related to, any act or omission occurring prior to the time of such termination. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto
and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and
legal representatives.

Company representing more than 50% of the combined voting power of the Company’s then outstanding securities, unless the change in relative Beneficial Ownership of the Company’s securities by any Person results solely from a reduction in

nomination for election was previously so approved, cease for any reason to constitute at least a majority of the members of the Board; 

(iii) Corporate Transactions. The effective date of a merger or consolidation of the Company with any other entity,
other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being converted into voting

firm, or a member of a law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five (5) years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either
such party (other than with respect to matters concerning Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification
hereunder. Notwithstanding the foregoing, the term “Independent Counsel” shall not include any Person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the

actual, threatened or completed proceeding, whether brought by or in the right of the Company or otherwise and whether civil, criminal, administrative or investigative, in which Indemnitee was, is or will be involved as a party or otherwise, by
reason of the fact that Indemnitee is or was an officer or director of the Company, by reason of any action taken by Indemnitee or of any inaction on Indemnitee’s part while acting as an officer or director of the Company, or by reason of the
fact that Indemnitee is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, trust or other enterprise; in each case whether or not Indemnitee is acting
or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this Agreement; including one pending on or before the date of this Agreement, but excluding one initiated by an
Indemnitee pursuant to Section 7 of this Agreement to enforce Indemnitee’s rights under this Agreement. 

13. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason
whatsoever: (i) the validity, legality, and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision held to
be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (ii) such provision or
provisions shall be deemed reformed to the fullest extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (iii) to the fullest extent possible, the provisions of this Agreement
(including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed
so as to give effect to the intent manifested thereby. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee and Nominating Member indemnification rights to the fullest extent permitted by applicable
laws. 
 14. Enforcement and Binding Effect. 

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

  
 15 













 (b) Without limiting any of the rights of Indemnitee under the Charter or Bylaws of the
Company as they may be amended from time to time, this Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied,
between the parties hereto with respect to the subject matter hereof. 
 (c) The indemnification and advancement of expenses provided by,
or granted pursuant to, this Agreement shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business or assets of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company or of any other Enterprise at the Company’s request, and shall inure to
the benefit of Indemnitee and Indemnitee’s spouse, assigns, heirs, devisees, executors and administrators and other legal representatives. 

(d) The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place.

 (e) The Company and Indemnitee agree herein that a monetary remedy for breach of this Agreement, at some later date, may be inadequate,
impracticable and difficult of proof, and further agree that such breach may cause Indemnitee irreparable harm. Accordingly, the parties hereto agree that Indemnitee may enforce this Agreement by seeking injunctive relief and/or specific performance
hereof, without any necessity of showing actual damage or irreparable harm and that by seeking injunctive relief and/or specific performance, Indemnitee shall not be precluded from seeking or obtaining any other relief to which Indemnitee may be
entitled. The Company and Indemnitee further agree that Indemnitee shall be entitled to such specific performance and injunctive relief, including temporary restraining orders, preliminary injunctions and permanent injunctions, without the necessity
of posting bonds or other undertaking in connection therewith. The Company acknowledges that in the absence of a waiver, a bond or undertaking may be required of Indemnitee by the court, and the Company hereby waives any such requirement of such a
bond or undertaking. 
 15. Modification and Waiver. No supplement, modification, termination or amendment of this Agreement shall be
binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver
constitute a continuing waiver. 

  
 16 













 16. Notice By Indemnitee. Indemnitee agrees promptly to notify the Company in writing
upon being served with or otherwise receiving any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement of Expenses covered
hereunder. The failure to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise unless and only to the extent that such failure or delay materially prejudices the
Company. 
 17. Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing and shall
