 This
Quota Share Reinsurance Agreement (the “Agreement”), effective as of the Coinsurance Effective Date, is made and entered into by and between Oscar Insurance Company, a Texas domiciled insurance company (the

“Parties”). 
 RECITALS 

WHEREAS, the Reinsured is, among other things, engaged in the business of underwriting, marketing, selling, issuing, renewing and servicing commercial health

 WHEREAS, the Reinsured desires to cede on a [***] indemnity quota share reinsurance basis to
the Reinsurer, as of the Coinsurance Effective Date (as defined below), all of the commercial health insurance products for individuals and small employers that it writes in the United States (the “Subject Business”), subject to the
terms and conditions stated herein; 
 WHEREAS, the Reinsurer desires to reinsure on such basis the Subject Business; and 

WHEREAS, this Agreement is an agreement solely between the Reinsured and the Reinsurer and performance of the obligations of each Party under this Agreement
will be rendered solely to the other Party. 
 NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, the Parties hereby
agree as follows: 
 ARTICLE I [***] QUOTA SHARE REINSURANCE OF SUBJECT BUSINESS 

The reinsurance provided by the Reinsurer under this Agreement is in respect of all policies of the Subject Business effected, bound, sold, issued, entered
into, renewed or reinstated, as applicable, by the Reinsured on or after the Coinsurance Effective Date, through the Agreement Period, and on or prior to the Termination Date (as such terms are defined below) on the following basis: 

 

	 	(i)	 For calendar year 2019: 

 

	 	(a)	 In respect of all policies of the Subject Business written by the Reinsured that is not subject to the AXA
quota share reinsurance agreement entered into with the Reinsured for calendar year 2019 (the “Inuring AXA Ceded Reinsurance”) and the Odyssey Re excess of loss reinsurance agreement entered into with the Reinsured for calendar year
2019 (the “Inuring Ceded Odyssey Re XOL Reinsurance”), the reinsurance provided by the Reinsurer under this Agreement shall apply on a [***]% quota share basis; and 

	 	(b)	 In respect of all policies of the Subject Business written by the Reinsured that is subject to the Inuring AXA
Ceded Reinsurance and/or the Inuring Ceded Odyssey Re XOL Reinsurance, as applicable, in each case, for calendar year 2019, the reinsurance provided by the Reinsurer under this Agreement shall apply on a [***]% quota share basis to all such policies
of the Subject Business retained net and un-reinsured by the Reinsured after such cession under the Inuring AXA Ceded Reinsurance and/or the Inuring Ceded Odyssey Re XOL Reinsurance, as applicable.

  

	 	(ii)	 For calendar year 2020 and, if applicable, the remainder of the Agreement Period: 

In respect of all policies of the Subject Business written by the Reinsured that is subject to any excess of loss reinsurance agreement for
calendar year 2020 and, if applicable, the remainder of the Agreement Period1 that may be entered into from time to time with the Reinsured, such excess of loss reinsurance to be substantially
similar to, in coverage and amount, as the Inuring Ceded Odyssey Re XOL Reinsurance that was in place for calendar year 2019 (such excess of loss reinsurance, the “Other Inuring Ceded XOL Reinsurance”), the reinsurance
provided by the Reinsurer under this Agreement shall apply on a [***]% quota share basis to all such policies of the Subject Business retained net and un-reinsured by the Reinsured after such cession
under the Other Inuring Ceded XOL Reinsurance. 
 For the avoidance of doubt, the Inuring Ceded Odyssey Re XOL Reinsurance for calendar year 2019, and the
Other Inuring Ceded XOL Reinsurance for calendar year 2020 and, if applicable, the remainder of the Agreement Period, shall each be maintained by the Reinsured during its applicable calendar year period, as specified immediately above in this
ARTICLE I, and shall be deemed, for purposes of this Agreement, as inuring to this Agreement and the reinsurance being provided hereunder by the Reinsurer during its applicable calendar year period specified above. 

ARTICLE II AGREEMENT PERIOD 
 The
reinsurance provided by the Reinsurer under this Agreement covers the Subject Business during the time period commencing at 12:01 AM Eastern Time on January 1, 2019 (the “Coinsurance Effective Date”) and terminating at 12:00 AM
(midnight) Eastern Time on December 31, 2020 (such period, the “Initial Agreement Period”). The Initial Agreement Period, together with any extensions thereof, if any, by the Reinsurer as provided in this ARTICLE II,
shall be referred to hereafter as the “Agreement Period”. Except as provided in ARTICLE XXX, this Agreement cannot be terminated during the Agreement Period by either Party. The Initial Agreement Period shall be subject to
the following unilateral right of the Reinsurer to extend it: the Reinsurer has the right, but not the obligation, to choose, by providing the Reinsured with prior 
  

 

	1 	 Note to Draft: This is to pick up any extension period of the Agreement Period by the Reinsurer.

  
 2 

 written notice no later than ten (10) days prior to the expiration of the then current Agreement
Period, to extend the Agreement Period for an additional one (1) year period should the Reinsurer not have realized a [***]% margin on its quota share participation in this Agreement at any time prior to the expiration of the then current
Agreement Period, as set forth in ARTICLE VII hereof. 
 ARTICLE III TERRITORIAL SCOPE 

The territorial scope of this Agreement shall be wherever in the United States the Reinsured issues the Subject Business. 

ARTICLE IV REINSURANCE PREMIUM AND CEDING COMMISSION 

In consideration of the reinsurance provided by the Reinsurer under this Agreement, the Reinsured shall pay to the Reinsurer its quota share participation in
all Premiums received by the Reinsured in connection with the Subject Business which shall be payable to the Reinsurer in cash in accordance with ARTICLE XIII. The only deduction allowable from the Reinsurer’s quota share participation
in the Premiums shall be a [***]% ceding commission payable by the Reinsurer to the Reinsured (the “Ceding Commission”). 
 ARTICLE
V PREMIUM ADJUSTMENTS 
 The Reinsurer’s quota share participation in all Premiums, which Premiums were received by the Reinsurer, that
are required to be refunded, rebated or otherwise repaid by the Reinsured to a Policyholder or Governmental Authority due to, (i) changes in or cancellations of any policy of the Subject Business, (ii) contractual requirements under the
terms of the policies of the Subject Business, or (iii) Applicable Law including the ACA Risk Adjustment Program, and any such refunds, rebates or payments resulting from (x) a finding in a commercial risk adjustment audit by any federal
Governmental Authority or a self-audit performed by the Reinsured that the Premiums were incorrect, and (y) any ACA Rebates (to the extent such rebates are related to the policies of the Subject Business, as solely determined by the Reinsured)
(paragraphs (i), (ii), and (iii) of this ARTICLE V, collectively, the “Premium Adjustments”), shall be refunded by the Reinsurer to the Reinsured in accordance with ARTICLE XIII. The Parties shall promptly make
all necessary financial adjustments between them with respect to the Maximum Combined Ratio, Profit Commission, and the Reinsurer’s Margin necessitated by any such Premium Adjustments in a manner consistent with the terms herein. 

This ARTICLE V will survive the termination or expiration of this Agreement. 

ARTICLE VI MAXIMUM COMBINED RATIO 
 Under no
circumstances whatsoever, howsoever arising, will the Reinsurer be liable for any sums in excess of a combined ratio of Ultimate Net Loss to the Reinsurer’s quota share participation in the Premiums actually received by the Reinsurer (i.e.,
after deducting the Ceding Commission from such Premiums) of [***]% in the aggregate during any calendar year period (the “Maximum Combined Ratio”). For the avoidance of doubt, any Ceding Commission paid to the Reinsured or
other deductions from the Reinsurer’s quota share participation in the Premiums payable to the Reinsurer hereunder shall be first deducted from such ceded Premiums in calculating the Maximum Combined Ratio, [***]. 

  
 3

 ARTICLE X SUBROGATION AND SALVAGE 

(A) The Reinsurer shall be subrogated, as respects any Ultimate Net Loss for which the Reinsurer shall actually pay or become liable to pay,
but only to the extent of the amount of payment by, or the amount of liability of, the Reinsurer, to all rights of the Reinsured against any Person who may be legally responsible in damages for said Ultimate Net Loss. The Reinsured hereby agrees to
use commercially reasonable efforts to enforce such rights. In the event the Reinsured shall fail or neglect to do so, the Reinsurer is hereby authorized and empowered to bring any commercially reasonable appropriate action in the name of the
Reinsured or in the name of a Policyholder under an insurance policy of the Subject Business reinsured hereunder to enforce such rights. 

(B) Any rights of subrogation, recoveries, salvages or reimbursements applying to loss occurrences reinsured under this Agreement shall always
be used to reimburse the reinsurers excess of the Reinsurer (from the last to the first, beginning with the reinsurer of the last excess) according to their participation, before being used in any way to reimburse the Reinsurer. The Reinsured shall
recover for the retention from recoveries, salvages or reimbursements only after the Reinsurer has been reimbursed in full for its Ultimate Net Loss reimbursement payment. In determining the amount of recoveries, salvages or reimbursements, there
shall first be deducted from any amount recovered the expenses incurred in effecting the recovery (excluding salaries and expenses of officers and employees of the Reinsured). 

(C) All salvages, recoveries or reimbursements, after deduction of all expenses allowed under paragraph (B) of this ARTICLE
X applicable thereto, recovered or received subsequent to an Ultimate Net Loss reimbursement to the Reinsured by the Reinsurer under this Agreement shall be applied as if recovered or received prior to the aforesaid settlement and all necessary
adjustments shall be made by the Parties hereto; provided that nothing in this ARTICLE X shall be construed to mean that Ultimate Net Losses under this Agreement are not recoverable until all salvage, recovery and reimbursement has been
determined. 
 ARTICLE XI INURING THIRD PARTY CEDED REINSURANCE 

The amount of the Reinsurer’s liability in respect of any Ultimate Net Loss shall not be increased by the inability of the Reinsured to collect from any
other reinsurer(s), whether specific or general, any amounts which may have become due from them regardless of whether such inability arises from the insolvency of such other reinsurers or for any other reason whatsoever. 

ARTICLE XII CURRENCY 
 Wherever the word
“Dollars” of the symbol “$” appears in this Agreement, it shall mean United States dollars. All payments under this Agreement shall be made in Dollars. 

ARTICLE XIII REPORTS AND REIMBURSEMENTS 

Accounts shall be submitted by the Reinsured to the Reinsurer on a quarterly basis, in arrears. Within 30 days of the end of each calendar quarter, the
Reinsured shall submit to the Reinsurer a statement setting forth the Reinsurer’s quota share participation in the Premiums payable to the 

  
 7 

 
Reinsurer hereunder, Premium Adjustments, Ultimate Net Loss activity, reserves (including IBNR reserves), etc., in each case, for the prior calendar quarter, and within thirty (30) days of
the end of each calendar year, the Reinsured shall submit to the Reinsurer a statement setting forth the Profit Commission due the Reinsured, if any, under ARTICLE VII for the prior calendar year. Any net balance payable to or from either
Party shall be paid by the debtor Party within 15 days of the receipt of such statement. The form of the quarterly and calendar year statements and the information set out therein shall be mutually agreed as between the Parties, and subject to the
Parties’ mutual amendments, as the Parties may agree from time to time. This ARTICLE XIII will survive the termination or expiration of this Agreement. 

ARTICLE XIV LIABILITY AND PAYMENT 
 The
Reinsured’s good faith determinations regarding its liabilities under the policies of the Subject Business, including the Reinsured’s decisions to adjust, settle, and compromise all Claims will bind the Reinsurer. Notwithstanding anything
contained in this Agreement to the contrary, the liability of the Reinsurer with respect to Claims will follow the liability of the Reinsured in all respects and will be subject to all good faith interpretations of contract provisions in the
policies of the Subject Business by the Reinsured including interpretations resulting in the payment of Claims. Notwithstanding anything contained in this Agreement to the contrary, all such adjustments, settlements and compromises will be
unconditionally binding upon the Reinsurer in proportion to the Reinsurer’s quota share participation, the true intent of this Agreement being that the Reinsurer will, in every case to which this Agreement applies, follow the fortunes, and
follow the settlements of the Reinsured. 
 ARTICLE XV AUDIT AND INSPECTION 

The Parties will maintain complete and correct books and records relating to the policies of the Subject Business, Claims and their respective obligations
under this Agreement (the “Books and Records”). The Books and Records will be open to audit and reproduction by the Reinsured and Reinsurer and their respective designated representatives (collectively, the “Auditing
Parties,” and individually, the “Auditing Party”) at the expense of the Auditing Party at the office of the Audited Party (as defined below) during the Agreement Period, the Run-Off
Period and until one (1) year following the expiration of the Run-Off Period, upon reasonable advance written notice and for the sole purpose of confirming the compliance of the Party being audited (the
“Audited Party”) with Applicable Law and/or its obligations, in each case, with respect to or under this Agreement; provided, that such audits shall be limited to not more than two (2) audits during any twelve
(12) calendar month period; provided, further, that such temporal limitation will not apply to any such audit that is required by Applicable Law. Such audits will occur only during normal business hours using reasonable care not to cause damage
and not to interrupt the normal business operations of the Audited Party and will be subject to, (i) such security procedures as the Audited Party may reasonably impose, and (ii) such limitations as may be required under Applicable Law
governing the conduct of the Audited Party’s business, or as may be otherwise reasonably required in order to protect from disclosure information of the Audited Party that does not relate to the policies of the Subject Business, Claims and the
Audited Party’s obligations under this Agreement. 

  
 8 

 ARTICLE XVI ERRORS AND OMISSIONS 

Any inadvertent error or omission on the part of either Party hereto shall not relieve the other Party from any liability which would have attached hereunder,
provided that such error or omission is rectified promptly upon discovery, and shall not impose any greater liability on the Reinsurer than would have attached hereunder if the error or omission had not occurred. 

ARTICLE XVII ADJUSTMENTS 
 Notwithstanding
anything contained herein to the contrary, if the Reinsured’s liability under any policy of the Subject Business is changed because of a misstatement of age, sex, marital status, smoking status, amount or nature of coverage, or any other
material fact by any Policyholder or its representative (including any employer, sponsor, group policyholder, broker, agent or other Person acting on behalf of the Policyholder), or in good faith by the Reinsured or by a Governmental Authority, the
Reinsurer will, (i) assume that portion of any increase in reinsured liabilities resulting from the change, and (ii) receive credit for that portion of any decrease in reinsured liabilities resulting from the change, and the Reinsured and
the Reinsurer will make all appropriate adjustments to amounts due each other under this Agreement. 
 ARTICLE XVIII CHANGES IN THE
AGREEMENT 
 The terms of this Agreement shall not be waived or changed except by written amendment executed by a duly authorized officer of the
Reinsurer and by a duly authorized officer or representative of the Reinsured. 
 ARTICLE XIX OFFSET CLAUSE 

The Reinsured or the Reinsurer may offset any balance(s) which may become due between them under this Agreement or any reinsurance agreement with an Oscar
Reinsured that is subject to the Interlocking provision herein. This offset right shall apply regardless of whether the balances arose on account of Premiums, commission, claims, losses, Allocated Loss Adjustment Expense, salvage or any other
amount(s) due from one Party to the other. 
 ARTICLE XX NO THIRD PARTY RIGHTS 

Except with respect to the Oscar Reinsureds, in no event shall anyone other than the Reinsurer or the Reinsured have any rights under this Agreement. 

ARTICLE XXI CHANGES IN OWNERSHIP AND ADMINISTRATIVE PRACTICES 

The Reinsured undertakes not to voluntarily make any material change in its established acceptance and underwriting policy in respect of the Subject Business,
nor to undergo any Change in Control, without, in each case, the prior consent of the Reinsurer, such consent not to be unreasonably withheld, denied or conditioned; provided, however, that such consent shall not be required if such
change is required by Applicable Law. It is furthermore understood and agreed that should a new affiliate to the Oscar Reinsureds be established for purposes of writing business similar to the Subject Business, the Parties hereto shall, subject to
Applicable Law and regulatory approval, mutually agree on a quota share reinsurance agreement in respect of such new affiliate and such business that shall be consistent with the terms and conditions hereof and subject to the same Interlocking
provision and principles set forth here. 

  
 9 

 ARTICLE XXII NON-WAIVER CLAUSE 

The failure of the Reinsured or the Reinsurer to insist on compliance with this Agreement or to exercise any right or remedy hereunder shall not constitute a
waiver of any rights or remedies contained herein nor estop either Party from thereafter demanding full and complete compliance nor prevent either Party from exercising such rights or remedy in the future. 

ARTICLE XXIII INSOLVENCY 
 In the event of
the Reinsured’s insolvency, any payments due the Reinsured from the Reinsurer pursuant to the terms of this Agreement will be made directly to the statutory successor of the Reinsured or its conservator, liquidator, or receiver without
diminution because of the insolvency of the Reinsured for those claims reported and allowed against the Reinsured by any court of competent jurisdiction or by the liquidator, rehabilitator, receiver or statutory successor having authority over such
claims. The conservator, liquidator, receiver or statutory successor of the Reinsured will give the Reinsurer written notice of the pendency of a claim against the Reinsured on any policy of the Subject Business within a reasonable time after such
claim is filed in the insolvency proceeding. During the pendency of any such claim, the Reinsurer may investigate such claim and interpose in the Reinsured’s name (or in the name of the Reinsured’s conservator, liquidator, receiver or
statutory successor), in the proceeding where such claim is to be adjudicated, any defense or defenses which the Reinsurer may deem available to the Reinsured or its conservator, liquidator, receiver or statutory successor. The expense thus incurred
by the Reinsurer will be chargeable, subject to court approval, against the Reinsured as a part of the expense of liquidation to the extent of a proportionate share of the benefit which may accrue to the Reinsured solely as a result of the defense
undertaken by the Reinsurer. 
 ARTICLE XXIV NO INTERMEDIARY 

This Reinsurance has been negotiated and agreed solely between the Parties hereto and no broker or intermediary has represented either Party or is entitled to
any remuneration. 
 ARTICLE XXV PAYMENTS 

All ceded Premiums and Ultimate Net Loss reimbursement settlements shall be made directly between the Reinsurer and the Reinsured; provided that the
Reinsured may appoint as Reinsured’s agent for the payment of ceded Premiums and acceptance of Ultimate Net Loss settlements any one Oscar Reinsured it so chooses, from time to time, by providing written notice thereof to the Reinsurer. 

  
 10 

 ARTICLE XXVI DELAYED PAYMENTS 

For purposes of any payments due hereunder, if there is a delayed settlement of a payment due, interest will accrue on such payment at the Applicable Interest
Rate. Interest will be calculated on the basis of actual days for a 365-day year based on the actual number of days elapsed. For purposes of this Agreement, a payment will be considered overdue, and such
interest will begin to accrue, on the date which is thirty (30) days after the date such payment is due. 
 ARTICLE XXVII CREDIT FOR
REINSURANCE 
 The Parties intend that the Reinsured will receive, from and after the Coinsurance Effective Date, full statutory reserve financial
statement credit for the reinsurance provided under this Agreement in the Reinsured’s state of domicile. If the Reinsured nevertheless loses statutory reserve financial statement credit in the Reinsured’s state of domicile due to any
reason attributable to the Reinsurer, the Reinsurer’s business, operations, condition, licenses and/or authorizations (including any losses thereof or restrictions thereon) or to a change in Applicable Law (collectively, a “Coinsurance
Credit Event”), or if the Reinsured is notified in writing by a Governmental Authority that it will not receive statutory reserve financial statement credit for the reinsurance provided under this Agreement due to a Coinsurance Credit
Event, the Reinsurer will promptly, and in any event will no later than thirty (30) calendar days following receipt of written notice from the Reinsured that a Coinsurance Credit Event has occurred, (i) cure such Coinsurance Credit Event
to the Parties’ mutual satisfaction and at the Reinsurer’s sole cost and expense, and/or (ii) establish for the benefit of the Reinsured, at the Reinsurer’s sole cost and expense, such trust accounts, letters of credit, funds
withheld, or other security permitted by Applicable Law to allow the Reinsured to obtain full statutory reserve financial statement credit for reinsurance provided under this Agreement in the Reinsured’s state of domicile. Subject to the
preceding two sentences, in the event of a Coinsurance Credit Event, the Reinsurer will have the option of determining the method of security to be utilized for such purpose. If such method elected by the Reinsurer requires any change to this
Agreement in order for the Reinsured to obtain such statutory reserve financial statement credit, the Parties will cooperate in good faith to promptly amend this Agreement to incorporate such change. Any trust accounts, letters of credit, funds
withheld, or other security established by the Reinsurer under this ARTICLE XXVII to address a Coinsurance Credit Event as set forth herein shall only be required to be maintained for so long a period as the Reinsured cannot receive full
statutory reserve financial statement credit for the reinsurance provided under this Agreement in the Reinsured’s state of domicile, and the Reinsured shall reasonably cooperate in the release of any such security should the Reinsured’s
ability to receive full statutory reserve financial statement credit for the reinsurance provided under this Agreement in the Reinsured’s state of domicile without such security be fully restored. This ARTICLE XXVII will survive the
termination or expiration of this Agreement. 
 ARTICLE XXVIII ARBITRATION CLAUSE 

This Clause shall form a separate agreement between the Reinsured and the Reinsurer from the main Agreement. 

  
 11 

 All matters in difference between the Reinsured and the Reinsurer (hereinafter referred to as the
“Disputing Parties”) in relation to this reinsurance, including its formation and validity, and whether arising during or after the period of this reinsurance, shall be referred to an Arbitration Tribunal in the manner hereinafter
set out. 
 Unless the Disputing Parties agree upon a single Arbitrator within thirty days of one receiving a written request from the other for
Arbitration, the Claimant (the Disputing Party requesting Arbitration) shall appoint its Arbitrator and give written notice thereof to the Respondent. Within thirty days of receiving such notice the Respondent shall appoint its Arbitrator and give
written notice thereof to the Claimant, failing which the Claimant may nominate an Arbitrator on behalf of the Respondent. 
 Should the Arbitrators fail to
agree, they shall appoint, by mutual agreement or by a mutually agreed selection process, an Umpire to whom the matter in difference shall be referred. 

Unless the Disputing Parties otherwise agree, the Arbitration Tribunal shall consist of persons employed or engaged in a senior position in insurance or
reinsurance underwriting or claims. 
 The Arbitration Tribunal shall have the power to fix all procedural rules for the holding of the Arbitration
including discretionary power to make orders as to any matters which it may consider proper in the circumstances of the case with regard to pleadings, discovery, inspection of documents, examination of witnesses and any other matter whatsoever
relating to the conduct of the Arbitration and may receive and act upon such evidence whether oral or written strictly admissible or not as it shall in its discretion think fit. 

All costs and expenses including attorneys’ fees, arbitrator fees, and expert fees of the Arbitration shall be in the discretion of the Arbitration
Tribunal who may direct to and by whom and in what manner they shall be paid. 
 The seat of the Arbitration shall be in New York, NY and the Arbitration
Tribunal shall apply the laws of the state of domicile of the Reinsured, without regard to such state’s principles of conflict of laws that could compel the application of the laws of another jurisdiction, as the proper law of this reinsurance.

 The Arbitration Tribunal may not award exemplary, punitive, multiple or other damages of a similar nature. 

The award of the Arbitration Tribunal shall be in writing and binding upon the Disputing Parties who covenant to carry out the same. If either of the
Disputing Parties should fail to carry out any award the other may apply for its enforcement to a court of competent jurisdiction in any territory in which the Disputing Party in default is domiciled or has assets or carries on business.

QUOTA SHARE REINSURANCE AGREEMENT 
 This
Quota Share Reinsurance Agreement (the “Agreement”), effective as of the Coinsurance Effective Date, is made and entered into by and between Oscar Health Plan of California, a California Health Care Service Plan (the
“Reinsured”), and National Indemnity Company, a Nebraska domiciled insurance company (the “Reinsurer”) (the Reinsured and the Reinsurer each individually, a “Party”, and collectively, the
“Parties”). 
 RECITALS 

WHEREAS, the Reinsured is, among other things, engaged in the business of underwriting, marketing, selling, issuing, renewing and servicing health care
service plan products for individuals and small employers in California; 
 WHEREAS, the Reinsurer, among other things, is authorized under Applicable Law
to assume reinsurance of such health care service plan products; 
 WHEREAS, the Reinsured desires to cede on a [***] indemnity quota share reinsurance
basis to the Reinsurer, as of the Coinsurance Effective Date (as defined below), all of the commercial health care service plan products for individuals and small employers that it writes in the State of California (the “Subject
Business”), subject to the terms and conditions stated herein; 
 WHEREAS, the Reinsurer desires to reinsure on such basis the Subject Business;
and 
 WHEREAS, this Agreement is an agreement solely between the Reinsured and the Reinsurer and performance of the obligations of each Party under this
Agreement will be rendered solely to the other Party. 
 NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, the
Parties hereby agree as follows: 
 ARTICLE I [***] QUOTA SHARE REINSURANCE OF SUBJECT BUSINESS 

The reinsurance provided by the Reinsurer under this Agreement is in respect of all health plan products (referred to in this Agreement as “
policies”) of the Subject Business effected, bound, sold, issued, entered into, renewed or reinstated, as applicable, by the Reinsured on or after the Coinsurance Effective Date, through the Agreement Period, and on or prior to the Termination
Date (as such terms are defined below) on the following basis: 
  

	 	(i)	 For calendar year 2019: 

 

	 	(a)	 In respect of all policies of the Subject Business written by the Reinsured that is not subject to the AXA
quota share reinsurance agreement entered into with the Reinsured for calendar year 2019 (the “Inuring AXA Ceded Reinsurance”) and the Odyssey Re excess of loss reinsurance agreement entered into with the Reinsured for calendar year
2019 (the “Inuring Ceded Odyssey Re XOL Reinsurance”), the reinsurance provided by the Reinsurer under this Agreement shall apply on a [***]% quota share basis; and 

	 	(b)	 In respect of all policies of the Subject Business written by the Reinsured that is subject to the Inuring AXA
Ceded Reinsurance and/or the Inuring Ceded Odyssey Re XOL Reinsurance, as applicable, in each case, for calendar year 2019, the reinsurance provided by the Reinsurer under this Agreement shall apply on a [***]% quota share basis to all such policies
of the Subject Business retained net and un-reinsured by the Reinsured after such cession under the Inuring AXA Ceded Reinsurance and/or the Inuring Ceded Odyssey Re XOL Reinsurance, as applicable.

  

	 	(ii)	 For calendar year 2020 and, if applicable, the remainder of the Agreement Period: 

In respect of all policies of the Subject Business written by the Reinsured that is subject to any excess of loss reinsurance agreement for
calendar year 2020 and, if applicable, the remainder of the Agreement Period that may be entered into from time to time with the Reinsured, such excess of loss reinsurance to be substantially similar to, in coverage and amount, as the Inuring Ceded
Odyssey Re XOL Reinsurance that was in place for calendar year 2019 (such excess of loss reinsurance, the “Other Inuring Ceded XOL Reinsurance”), the reinsurance provided by the Reinsurer under this Agreement shall apply on a
[***]% quota share basis to all such policies of the Subject Business retained net and un-reinsured by the Reinsured after such cession under the Other Inuring Ceded XOL Reinsurance. 

For the avoidance of doubt, the Inuring Ceded Odyssey Re XOL Reinsurance for calendar year 2019, and the Other Inuring Ceded XOL Reinsurance for calendar year
2020 and, if applicable, the remainder of the Agreement Period, shall each be maintained by the Reinsured during its applicable calendar year period, as specified immediately above in this ARTICLE I, and shall be deemed, for purposes of this
Agreement, as inuring to this Agreement and the reinsurance being provided hereunder by the Reinsurer during its applicable calendar year period specified above. 

ARTICLE II AGREEMENT PERIOD 
 The
reinsurance provided by the Reinsurer under this Agreement covers the Subject Business during the time period commencing at 12:01 AM Eastern Time on January 1, 2019 (the “Coinsurance Effective Date”) and terminating at 12:00 AM
(midnight) Eastern Time on December 31, 2020 (such period, the “Initial Agreement Period”). The Initial Agreement Period, together with any extensions thereof, if any, by the Reinsurer as provided in this ARTICLE II,
shall be referred to hereafter as the “Agreement Period”. Except as provided in ARTICLE XXX, 

  
 2 

 this Agreement cannot be terminated during the Agreement Period by either Party. The Initial Agreement
Period shall be subject to the following unilateral right of the Reinsurer to extend it: the Reinsurer has the right, but not the obligation, to choose, by providing the Reinsured with prior written notice no later than ten (10) days prior to
the expiration of the then current Agreement Period, to extend the Agreement Period for an additional one (1) year period should the Reinsurer not have realized a [***]% margin on its quota share participation in this Agreement at any time
prior to the expiration of the then current Agreement Period, as set forth in ARTICLE VII hereof. 
 ARTICLE III TERRITORIAL SCOPE

 The territorial scope of this Agreement shall be wherever in the United States the Reinsured issues the Subject Business. 

ARTICLE IV REINSURANCE PREMIUM AND CEDING COMMISSION 

In consideration of the reinsurance provided by the Reinsurer under this Agreement, the Reinsured shall pay to the Reinsurer its quota share participation in
all Premiums received by the Reinsured in connection with the Subject Business which shall be payable to the Reinsurer in cash in accordance with ARTICLE XIII. The only deduction allowable from the Reinsurer’s quota share participation
in the Premiums shall be a [***]% ceding commission payable by the Reinsurer to the Reinsured (the “Ceding Commission”). 
 ARTICLE
V PREMIUM ADJUSTMENTS 
 The Reinsurer’s quota share participation in all Premiums, which Premiums were received by the Reinsurer, that
are required to be refunded, rebated or otherwise repaid by the Reinsured to a Policyholder or Governmental Authority due to, (i) changes in or cancellations of any policy of the Subject Business, (ii) contractual requirements under the
terms of the policies of the Subject Business, or (iii) Applicable Law including the ACA Risk Adjustment Program, and any such refunds, rebates or payments resulting from (x) a finding in a commercial risk adjustment audit by any federal
Governmental Authority or a self-audit performed by the Reinsured that the Premiums were incorrect, and (y) any ACA Rebates (to the extent such rebates are related to the policies of the Subject Business, as solely determined by the Reinsured)
(paragraphs (i), (ii), and (iii) of this ARTICLE V, collectively, the “Premium Adjustments”), shall be refunded by the Reinsurer to the Reinsured in accordance with ARTICLE XIII. The Parties shall promptly make
all necessary financial adjustments between them with respect to the Maximum Combined Ratio, Profit Commission, and the Reinsurer’s Margin necessitated by any such Premium Adjustments in a manner consistent with the terms herein. 

This ARTICLE V will survive the termination or expiration of this Agreement. 

ARTICLE VI MAXIMUM COMBINED RATIO 
 Under no
circumstances whatsoever, howsoever arising, will the Reinsurer be liable for any sums in excess of a combined ratio of Ultimate Net Loss to the Reinsurer’s quota share participation in the Premiums actually received by the Reinsurer (i.e.,
after deducting the Ceding Commission from such Premiums) of [***]% in the aggregate during any calendar year period (the “Maximum Combined Ratio”). For the avoidance of doubt, any Ceding Commission paid to the Reinsured or
other deductions from the Reinsurer’s quota share participation in the Premiums payable to the Reinsurer hereunder shall be first deducted from such ceded Premiums in calculating the Maximum Combined Ratio, [***]. 

  
 3 

 ARTICLE VII PROFIT COMMISSION 

Reinsured shall be paid a profit commission by the Reinsurer in an amount equal to any profit resulting from this Agreement from a [***] combined ratio during
any calendar year period (the “Profit Commission”) (i.e., the Reinsurer shall retain a margin of [***]% (the “Reinsurer’s Margin”)). Payment to the Reinsured of the Profit Commission shall be made in

 ARTICLE X SUBROGATION AND SALVAGE 

(A) The Reinsurer shall be subrogated, as respects any Ultimate Net Loss for which the Reinsurer shall actually pay or become liable to pay,
but only to the extent of the amount of payment by, or the amount of liability of, the Reinsurer, to all rights of the Reinsured against any Person who may be legally responsible in damages for said Ultimate Net Loss. The Reinsured hereby agrees to
use commercially reasonable efforts to enforce such rights. In the event the Reinsured shall fail or neglect to do so, the Reinsurer is hereby authorized and empowered to bring any commercially reasonable appropriate action in the name of the
Reinsured or in the name of a Policyholder under an insurance policy of the Subject Business reinsured hereunder to enforce such rights. 

(B) Any rights of subrogation, recoveries, salvages or reimbursements applying to loss occurrences reinsured under this Agreement shall always
be used to reimburse the reinsurers excess of the Reinsurer (from the last to the first, beginning with the reinsurer of the last excess) according to their participation, before being used in any way to reimburse the Reinsurer. The Reinsured shall
recover for the retention from recoveries, salvages or reimbursements only after the Reinsurer has been reimbursed in full for its Ultimate Net Loss reimbursement payment. In determining the amount of recoveries, salvages or reimbursements, there
shall first be deducted from any amount recovered the expenses incurred in effecting the recovery (excluding salaries and expenses of officers and employees of the Reinsured). 

(C) All salvages, recoveries or reimbursements, after deduction of all expenses allowed under paragraph (B) of this ARTICLE
X applicable thereto, recovered or received subsequent to an Ultimate Net Loss reimbursement to the Reinsured by the Reinsurer under this Agreement shall be applied as if recovered or received prior to the aforesaid settlement and all necessary
adjustments shall be made by the Parties hereto; provided that nothing in this ARTICLE X shall be construed to mean that Ultimate Net Losses under this Agreement are not recoverable until all salvage, recovery and reimbursement has been
determined. 
 ARTICLE XI INURING THIRD PARTY CEDED REINSURANCE 

The amount of the Reinsurer’s liability in respect of any Ultimate Net Loss shall not be increased by the inability of the Reinsured to collect from any
other reinsurer(s), whether specific or general, any amounts which may have become due from them regardless of whether such inability arises from the insolvency of such other reinsurers or for any other reason whatsoever. 

ARTICLE XII CURRENCY 
 Wherever the word
“Dollars” of the symbol “$” appears in this Agreement, it shall mean United States dollars. All payments under this Agreement shall be made in Dollars. 

  
 7 

 ARTICLE XIII REPORTS AND REIMBURSEMENTS 

Accounts shall be submitted by the Reinsured to the Reinsurer on a quarterly basis, in arrears. Within 30 days of the end of each calendar quarter, the
Reinsured shall submit to the Reinsurer a statement setting forth the Reinsurer’s quota share participation in the Premiums payable to the Reinsurer hereunder, Premium Adjustments, Ultimate Net Loss activity, reserves (including IBNR reserves),
etc., in each case, for the prior calendar quarter, and within thirty (30) days of the end of each calendar year, the Reinsured shall submit to the Reinsurer a statement setting forth the Profit Commission due the Reinsured, if any, under
ARTICLE VII for the prior calendar year. Any net balance payable to or from either Party shall be paid by the debtor Party within 15 days of the receipt of such statement. The form of the quarterly and calendar year statements and the
information set out therein shall be mutually agreed as between the Parties, and subject to the Parties’ mutual amendments, as the Parties may agree from time to time. This ARTICLE XIII will survive the termination or expiration of this
Agreement. 
 ARTICLE XIV LIABILITY AND PAYMENT 

The Reinsured’s good faith determinations regarding its liabilities under the policies of the Subject Business, including the Reinsured’s decisions
to adjust, settle, and compromise all Claims will bind the Reinsurer. Notwithstanding anything contained in this Agreement to the contrary, the liability of the Reinsurer with respect to Claims will follow the liability of the Reinsured in all
respects and will be subject to all good faith interpretations of contract provisions in the policies of the Subject Business by the Reinsured including interpretations resulting in the payment of Claims. Notwithstanding anything contained in this
Agreement to the contrary, all such adjustments, settlements and compromises will be unconditionally binding upon the Reinsurer in proportion to the Reinsurer’s quota share participation, the true intent of this Agreement being that the
Reinsurer will, in every case to which this Agreement applies, follow the fortunes, and follow the settlements of the Reinsured. 
 ARTICLE XV
AUDIT AND INSPECTION 
 The Parties will maintain complete and correct books and records relating to the policies of the Subject Business, Claims
and their respective obligations under this Agreement (the “Books and Records”). The Books and Records will be open to audit and reproduction by the Reinsured and Reinsurer and their respective designated representatives
(collectively, the “Auditing Parties,” and individually, the “Auditing Party”) at the expense of the Auditing Party at the office of the Audited Party (as defined below) during the Agreement Period, the Run-Off Period and until one (1) year following the expiration of the Run-Off Period, upon reasonable advance written notice and for the sole purpose of confirming the
compliance of the Party being audited (the “Audited Party”) with Applicable Law and/or its obligations, in each case, with respect to or under this Agreement; provided, that such audits shall be limited to not more than two
(2) audits during any twelve (12) calendar month period; provided, further, that such temporal limitation will not apply to any such audit that is required by Applicable Law. Such audits will occur only during normal business hours using
reasonable care not to cause damage and not to interrupt the normal business operations of the Audited Party and will be subject to, (i) such security procedures as the Audited Party may reasonably impose, and (ii) such limitations as may
be required under Applicable Law governing the conduct of the Audited Party’s business, or as may be otherwise reasonably required in order to protect from disclosure information of the Audited Party that does not relate to the policies of the
Subject Business, Claims and the Audited Party’s obligations under this Agreement. 

  
 8 

 ARTICLE XVI ERRORS AND OMISSIONS 

Any inadvertent error or omission on the part of either Party hereto shall not relieve the other Party from any liability which would have attached hereunder,
provided that such error or omission is rectified promptly upon discovery, and shall not impose any greater liability on the Reinsurer than would have attached hereunder if the error or omission had not occurred. 

ARTICLE XVII ADJUSTMENTS 
 Notwithstanding
anything contained herein to the contrary, if the Reinsured’s liability under any policy of the Subject Business is changed because of a misstatement of age, sex, marital status, smoking status, amount or nature of coverage, or any other
material fact by any Policyholder or its representative (including any employer, sponsor, group policyholder, broker, agent or other Person acting on behalf of the Policyholder), or in good faith by the Reinsured or by a Governmental Authority, the
Reinsurer will, (i) assume that portion of any increase in reinsured liabilities resulting from the change, and (ii) receive credit for that portion of any decrease in reinsured liabilities resulting from the change, and the Reinsured and
the Reinsurer will make all appropriate adjustments to amounts due each other under this Agreement. 
 ARTICLE XVIII CHANGES IN THE
AGREEMENT 
 The terms of this Agreement shall not be waived or changed except by written amendment executed by a duly authorized officer of the
Reinsurer and by a duly authorized officer or representative of the Reinsured. 
 ARTICLE XIX OFFSET CLAUSE 

The Reinsured or the Reinsurer may offset any balance(s) which may become due between them under this Agreement or any reinsurance agreement with an Oscar
Reinsured that is subject to the Interlocking provision herein. This offset right shall apply regardless of whether the balances arose on account of Premiums, commission, claims, losses, Allocated Loss Adjustment Expense, salvage or any other
amount(s) due from one Party to the other. 
 ARTICLE XX NO THIRD PARTY RIGHTS 

Except with respect to the Oscar Reinsureds, in no event shall anyone other than the Reinsurer or the Reinsured have any rights under this Agreement. 

ARTICLE XXI CHANGES IN OWNERSHIP AND ADMINISTRATIVE PRACTICES 

The Reinsured undertakes not to voluntarily make any material change in its established acceptance and underwriting policy in respect of the Subject Business,
nor to undergo any Change in Control, without, in each case, the prior consent of the Reinsurer, such consent not to be unreasonably withheld, denied or conditioned; provided, however, that such consent shall not be required if such
change is required by Applicable Law. It is furthermore understood and agreed that should a new affiliate to the Oscar Reinsureds be established for purposes of writing business similar to the Subject Business, the Parties hereto shall, subject to
Applicable Law and regulatory approval, mutually agree on a quota share reinsurance agreement in respect of such new affiliate and such business that shall be consistent with the terms and conditions hereof and subject to the same Interlocking
provision and principles set forth here. 

  
 9 

 ARTICLE XXII NON-WAIVER CLAUSE 

The failure of the Reinsured or the Reinsurer to insist on compliance with this Agreement or to exercise any right or remedy hereunder shall not constitute a
waiver of any rights or remedies contained herein nor estop either Party from thereafter demanding full and complete compliance nor prevent either Party from exercising such rights or remedy in the future. 

ARTICLE XXIII INSOLVENCY 
 In the event of
the Reinsured’s insolvency, any payments due the Reinsured from the Reinsurer pursuant to the terms of this Agreement will be made directly to the statutory successor of the Reinsured or its conservator, liquidator, or receiver without
diminution because of the insolvency of the Reinsured for those claims reported and allowed against the Reinsured by any court of competent jurisdiction or by the liquidator, rehabilitator, receiver or statutory successor having authority over such
claims. The conservator, liquidator, receiver or statutory successor of the Reinsured will give the Reinsurer written notice of the pendency of a claim against the Reinsured on any policy of the Subject Business within a reasonable time after such
claim is filed in the insolvency proceeding. During the pendency of any such claim, the Reinsurer may investigate such claim and interpose in the Reinsured’s name (or in the name of the Reinsured’s conservator, liquidator, receiver or
statutory successor), in the proceeding where such claim is to be adjudicated, any defense or defenses which the Reinsurer may deem available to the Reinsured or its conservator, liquidator, receiver or statutory successor. The expense thus incurred
by the Reinsurer will be chargeable, subject to court approval, against the Reinsured as a part of the expense of liquidation to the extent of a proportionate share of the benefit which may accrue to the Reinsured solely as a result of the defense
undertaken by the Reinsurer. 
 ARTICLE XXIV NO INTERMEDIARY 

This Reinsurance has been negotiated and agreed solely between the Parties hereto and no broker or intermediary has represented either Party or is entitled to
any remuneration. 
 ARTICLE XXV PAYMENTS 

All ceded Premiums and Ultimate Net Loss reimbursement settlements shall be made directly between the Reinsurer and the Reinsured; provided that the
Reinsured may appoint as Reinsured’s agent for the payment of ceded Premiums and acceptance of Ultimate Net Loss settlements any one Oscar Reinsured it so chooses, from time to time, by providing written notice thereof to the Reinsurer. 

  
 10 

 ARTICLE XXVI DELAYED PAYMENTS 

For purposes of any payments due hereunder, if there is a delayed settlement of a payment due, interest will accrue on such payment at the Applicable Interest
Rate. Interest will be calculated on the basis of actual days for a 365-day year based on the actual number of days elapsed. For purposes of this Agreement, a payment will be considered overdue, and such
interest will begin to accrue, on the date which is thirty (30) days after the date such payment is due. 
 ARTICLE XXVII CREDIT FOR
REINSURANCE 
 The Parties intend that the Reinsured will receive, from and after the Coinsurance Effective Date, full statutory reserve financial
statement credit for the reinsurance provided under this Agreement in the Reinsured’s state of domicile. If the Reinsured nevertheless loses statutory reserve financial statement credit in the Reinsured’s state of domicile due to any
reason attributable to the Reinsurer, the Reinsurer’s business, operations, condition, licenses and/or authorizations (including any losses thereof or restrictions thereon) or to a change in Applicable Law (collectively, a “Coinsurance
Credit Event”), or if the Reinsured is notified in writing by a Governmental Authority that it will not receive statutory reserve financial statement credit for the reinsurance provided under this Agreement due to a Coinsurance Credit
Event, the Reinsurer will promptly, and in any event will no later than thirty (30) calendar days following receipt of written notice from the Reinsured that a Coinsurance Credit Event has occurred, (i) cure such Coinsurance Credit Event
to the Parties’ mutual satisfaction and at the Reinsurer’s sole cost and expense, and/or (ii) establish for the benefit of the Reinsured, at the Reinsurer’s sole cost and expense, such trust accounts, letters of credit, funds
withheld, or other security permitted by Applicable Law to allow the Reinsured to obtain full statutory reserve financial statement credit for reinsurance provided under this Agreement in the Reinsured’s state of domicile. Subject to the
preceding two sentences, in the event of a Coinsurance Credit Event, the Reinsurer will have the option of determining the method of security to be utilized for such purpose. If such method elected by the Reinsurer requires any change to this
Agreement in order for the Reinsured to obtain such statutory reserve financial statement credit, the Parties will cooperate in good faith to promptly amend this Agreement to incorporate such change. Any trust accounts, letters of credit, funds
withheld, or other security established by the Reinsurer under this ARTICLE XXVII to address a Coinsurance Credit Event as set forth herein shall only be required to be maintained for so long a period as the Reinsured cannot receive full
statutory reserve financial statement credit for the reinsurance provided under this Agreement in the Reinsured’s state of domicile, and the Reinsured shall reasonably cooperate in the release of any such security should the Reinsured’s
ability to receive full statutory reserve financial statement credit for the reinsurance provided under this Agreement in the Reinsured’s state of domicile without such security be fully restored. This ARTICLE XXVII will survive the
termination or expiration of this Agreement. 
 ARTICLE XXVIII ARBITRATION CLAUSE 

This Clause shall form a separate agreement between the Reinsured and the Reinsurer from the main Agreement. 

  
 11 

 All matters in difference between the Reinsured and the Reinsurer (hereinafter referred to as the
“Disputing Parties”) in relation to this reinsurance, including its formation and validity, and whether arising during or after the period of this reinsurance, shall be referred to an Arbitration Tribunal in the manner hereinafter
set out. 
 Unless the Disputing Parties agree upon a single Arbitrator within thirty days of one receiving a written request from the other for
Arbitration, the Claimant (the Disputing Party requesting Arbitration) shall appoint its Arbitrator and give written notice thereof to the Respondent. Within thirty days of receiving such notice the Respondent shall appoint its Arbitrator and give
written notice thereof to the Claimant, failing which the Claimant may nominate an Arbitrator on behalf of the Respondent. 
 Should the Arbitrators fail to
agree, they shall appoint, by mutual agreement or by a mutually agreed selection process, an Umpire to whom the matter in difference shall be referred. 

Unless the Disputing Parties otherwise agree, the Arbitration Tribunal shall consist of persons employed or engaged in a senior position in insurance or
reinsurance underwriting or claims. 
 The Arbitration Tribunal shall have the power to fix all procedural rules for the holding of the Arbitration
including discretionary power to make orders as to any matters which it may consider proper in the circumstances of the case with regard to pleadings, discovery, inspection of documents, examination of witnesses and any other matter whatsoever
relating to the conduct of the Arbitration and may receive and act upon such evidence, whether oral or written strictly admissible or not as it shall in its discretion think fit. 

All costs and expenses including attorneys’ fees, arbitrator fees, and expert fees of the Arbitration shall be in the discretion of the Arbitration
Tribunal who may direct to and by whom and in what manner they shall be paid. 
 The seat of the Arbitration shall be in New York, NY and the Arbitration
Tribunal shall apply the laws of the state of domicile of the Reinsured, without regard to such state’s principles of conflict of laws that could compel the application of the laws of another jurisdiction, as the proper law of this reinsurance.

 The Arbitration Tribunal may not award exemplary, punitive, multiple or other damages of a similar nature. 

The award of the Arbitration Tribunal shall be in writing and binding upon the Disputing Parties who covenant to carry out the same. If either of the
Disputing Parties should fail to carry out any award the other may apply for its enforcement to a court of competent jurisdiction in any territory in which the Disputing Party in default is domiciled or has assets or carries on business. 

ARTICLE XXIX TERM 
 This Agreement will
commence on the Coinsurance Effective Date and run indefinitely unless earlier terminated as provided in ARTICLE XXX (the “Term”). 

  
 12 

 ARTICLE XXX TERMINATION 

Notwithstanding anything contained to the contrary in this Agreement, this Agreement may only be terminated as follows: 

 

	 	(b)	 If either Party to this Agreement fails to pay (the “Non-paying
Party”) the other Party an amount due within thirty (30) days after the due date provided in this Agreement, the other Party (the “Terminating Party”) may terminate this Agreement, subject to thirty (30) days
prior written notice to the Non-paying Party of the Terminating Party’s intention to terminate; provided, however, that the Non-paying Party may avoid
termination of this Agreement pursuant to this paragraph by paying all undisputed amounts that are delinquent and then due, including any interest owing thereon pursuant to ARTICLE XXVI, on or before the termination date specified in the
written notice; 

  

	 	(c)	 In the event that a Governmental Authority with jurisdiction over the Reinsured denies or revokes the ability
of the Reinsured to take full statutory reserve financial statement credit for the reinsurance provided under this Agreement due to a Coinsurance Credit Event, the Reinsured may terminate this Agreement, subject to thirty (30) days prior
written notice to the Reinsurer of the Reinsured’s intention to terminate; provided, however, that the Reinsurer may avoid termination of this Agreement pursuant to this paragraph by fully complying with ARTICLE XXVII prior
to the end of such thirty (30) day notice period; 

  

	 	(d)	 This Agreement may be terminated by either Party by giving written notice of termination to the other Party if
such termination is required by any Governmental Authority under Applicable Law; 

  

	 	(e)	 This Agreement may be terminated by either Party at any time after the third (3rd) year anniversary of the
Coinsurance Effective Date by giving written notice of termination to the other Party; and 

  

	 	(f)	 If one or more of the reinsurance agreements between the Reinsurer and the Oscar Reinsureds that are subject to
the Interlocking provision herein is terminated for reasons other than that such termination was required by a Governmental Authority under Applicable Law, either Party may terminate this Agreement within thirty (30) days following the
termination of such reinsurance agreement that is subject to the Interlocking provision herein by giving the other Party written notice of termination of this Agreement. 

  
 13 

 The effective date of termination of this Agreement (the “Termination Date”) for any notice
of termination properly delivered in accordance with this ARTICLE XXX, will be the date specified in such notice. 
 Upon the Termination Date of
this Agreement, subject to all other terms and conditions hereof including the Maximum Combined Ratio, the Reinsurer will remain liable for all reinsured liabilities under this Agreement with respect to each policy of the Subject Business that was
effected, bound, sold, issued, entered into, renewed or reinstated, as applicable, by the Reinsured on or prior to the Termination Date of this Agreement and the Reinsurer will remain liable for all such reinsurance until the end of the “Run-Off Period,” which will mean the period beginning on the Termination Date of this Agreement and continuing until the date on which the Reinsured has no further liabilities or obligations under any
policy of the Subject Business effected, bound, sold, issued, entered into, renewed or reinstated, as applicable, by the Reinsured on or prior to the Termination Date of this Agreement. For the avoidance of doubt, the Reinsured’s and the
Reinsurer’s respective obligation to pay the other all amounts due hereunder, as applicable, in accordance with the terms of this Agreement, with respect to the policies of the Subject Business that were effected, bound, issued, entered into,
renewed or reinstated, as applicable, by the Reinsured on or prior to the Termination Date of this Agreement, will extend during the Run-Off Period, as provided herein. The Parties hereto expressly agree that
they will reasonably cooperate with each other in the handling of all run-off obligations with respect to the policies of the Subject Business reinsured hereunder. 

Upon the Termination Date of this Agreement, no policies of the Subject Business effected, bound, sold, issued, renewed or reinstated, as applicable, by the
Reinsured after the Termination Date of this Agreement will be reinsured under this Agreement. 
 This ARTICLE XXX will survive the termination or
expiration of this Agreement.
