 TERMS 

1.     INCORPORATION OF RECITALS: The recitals set forth above are hereby incorporated into this Agreement as if fully set
forth herein and are legally binding. 
 2.     PAYMENT: Provider will pay to Cigna the total sum of TWELVE MILLION
($12,000,000) U.S. DOLLARS (the “Settlement Amount”), to be paid as follows: 
  

	 	a.	 Within [***] days of the mutual execution of this Settlement Agreement, Provider shall pay to “Cigna” the
total sum of [***] which shall be paid by bank check and sent to the following address with a cover letter referencing this Agreement: 



[***] 
  

	 	b.	 The remaining [***] shall be paid in [***] installments of [***], which shall be paid by either a bank check sent to
the above address, or by wire transfer. Each installment payment shall be due on the 1st day of each month beginning on [***], and ending on [***]. 



3.     REMOVAL OF FLAG: Within ten (10) business days of the mutual execution of this Settlement Agreement, Cigna will
lift any current edit or flag on Provider’s tax identification number as a result of the SIU investigation (hereinafter the “SIU Edit/Flag”). Cigna has various pre-existing claim and reimbursement edits, policies and procedures in
place, and may create or adopt additional claim and reimbursement edits, policies and procedures in the future. Nothing in this Agreement should be construed to limit Cigna’s ability to apply these current or future claim and reimbursement
edits, policies and procedures, or the underlying terms and conditions of any applicable health benefits plans, to any claims submitted by or on behalf of Provider in the future, provided one of the following conditions is met:(1) such claim or
reimbursement edit, flag, or policy and procedure is one of general applicability (i.e., it is applicable to providers that perform similar services as Provider); or (2) application of such claim or reimbursement edit, flag, or policy and
procedure is specific to Provider and is based on conduct by Provider that occurs after the Effective Date. The Parties understand that the lifting of the flag referenced in this Section 3 refers solely to the SIU Edit/Flag, and that this SIU
Edit/Flag or its functional equivalent may not be placed again on Provider at any point in the future except in the event of breach of this Agreement or Provider’s noncompliance with Cigna’s plan terms and/or coverage policies. In the
event that Provider breaches Section 2 of this Agreement by failing to timely make payment to Cigna, then the full Settlement Amount shall immediately become due and payable and Cigna shall have the right to place a flag on Provider’s TIN
that will deny all claims until the full Settlement Amount is paid.

 4.     PROVIDER BUSINESS PRACTICES: 

4.1     Provider agrees not to waive any portion of the cost share responsibility (i.e., copayment, deductible,
and/or coinsurance) and/or balance amounts if applicable (i.e., any portion of Provider’s billed charges that exceeds the allowed amounts under plan terms, excepting services Provider renders pursuant to a participating-provider agreement) of
Cigna plan participants and shall bill and obligate Cigna plan participants who receive services from Provider for these amounts in a timely and good faith manner. Cigna acknowledges that, for a variety of reasons, it is not always possible to
collect 100% of a patient’s cost share and balance amounts. Therefore, on a patient-by-patient basis, after Provider bills, obligates and uses reasonable efforts to collect the required cost share and balance amounts from a patient, Provider
may write off a patient’s cost share and/or balance amount from Provider’s accounting ledgers provided that (a) Provider has documented the efforts made to collect and the reasons supporting the write off (e.g., patient has
insufficient assets to pay); and (b) the patient remains obligated to pay the full amount of his/her required cost share and balance amount (e.g., Provider does not relinquish its right to pursue the obligation in the future). Provider will
submit claims to Cigna at rates or prices that are no greater than those quoted to Cigna plan participants, express or otherwise. Provider understands that, to the extent that Cigna pays future claims submitted by Provider, Cigna is relying on the
promises, representations and terms of this Agreement. 
 4.2     Provider agrees not to engage in any kickback
arrangements or patient brokering of any kind, which conduct includes, but is not limited to: (a) assisting patients in obtaining health insurance policies; (b) referring patients to health insurance policy brokers; (c) paying,
directly or indirectly, in whole or part, the premiums for any patients’ health insurance policies; (d) offering anything of value (e.g., airfare, money, tangible property, free housing) to patients to engage Provider’s services; and
(e) offering, giving or accepting anything of value to/from any other provider, entity or individual in exchange for patient referrals. 
 5.
    AUDITS: The Parties agree that Cigna has the right to audit Provider’s claims in the ordinary course of business to ensure compliance with the terms of Cigna’s health benefits plans, including, but not limited
to Cigna’s Medical Necessity Criteria and billing and collection criteria, except that Cigna shall not audit any claims submitted by Provider prior to the Effective Date. Provider agrees to cooperate and comply with Cigna’s audits. 

6.     REPRESENTATIONS AND WARRANTIES: 

Each Party makes the following covenants, representations and warranties to the other Party: 

6.1     The Party is correctly named and described in this Agreement, and, to the extent applicable, is duly
organized and existing under the laws of the applicable state, and is authorized and qualified to do all things required of it under this Agreement.

 6.4     The signatories for each Party
are fully authorized to enter into and execute this Agreement for and on behalf of the Party that he/she represents and they are duly authorized as such, as reflected on the attached signature page(s). 

6.5     Each Party completely and fully owns all rights to the causes of action that it releases in this Agreement
and has not assigned, pledged, or in any other manner sold, transferred, or alienated any right, title, or interest in any such causes of action.

7.     RELEASES / COVENANT NOT TO SUE:

Provider-Releasor, or the Provider-Releasor’s heirs, executors, administrators, successors, and permitted assigns, ever had, now have, or hereafter can, shall, or may have for, upon, or by reason of any matter, cause, or thing whatsoever from
the beginning of the world through and including the Effective Date of this Agreement.

 7.2     By Cigna: Upon the execution of this Agreement by
all Parties, except for the duties and obligations set forth in this Agreement, Cigna and its affiliates and subsidiaries (collectively as the “Payor-Releasor”) irrevocably releases, forever discharges and covenants not to sue
Provider and its affiliates and subsidiaries, and each of their owners, officers, directors, managers, partners, shareholders, members, and employees (individually and collectively, the “Provider-Releasee”), and each

through and including the Effective Date of this Agreement, which relates in any way to claims submitted by or services performed by Provider, or any acts or omissions of Provider that relate to Cigna. Any material breach of this Agreement by
Provider that remains uncured after [***] shall render this release void, however, any amounts paid by Provider to Cigna pursuant to this Agreement shall be an offset to any damages that Cigna may be entitled to. 

8.     NO ADMISSION OF LIABILITY: The giving or acceptance of this Agreement, the payment of the sums provided herein, and
the general releases contained herein, shall not constitute or be construed as an admission of any liability whatsoever by the Parties, or the admission of the validity of any claims that are the subject of this Agreement, it being the purpose of
this Agreement to settle the same and not to admit liability. 
 9.     CONFIDENTIALITY: Cigna and Provider and their
respective attorneys represent and agree that they will not publish, publicize, or disseminate or cause to be published, publicized or disseminated in any manner, information regarding the dispute that is the subject of this Agreement, or any
information obtained from Cigna or Provider regarding this matter, including, but not limited to, the contents of documents produced to Provider or Cigna or information about the details of the settlement or the terms of this Agreement.
Notwithstanding the foregoing, the information covered by this section may be disclosed by any Party for the following purposes: (a) to the extent necessary to report income to appropriate taxing authorities; (b) to the extent required by
federal or state laws and/or regulations; (c) to its accountants, contractors, lenders, Cigna clients or their employees whose claims are subject to this Agreement, attorneys or other professionals if such professionals agree to the same
confidentiality restrictions; and (d) in response to an order of a court of competent jurisdiction or subpoena issued under authority thereof, or in response to any inquiry or subpoena issued by a state or federal government agency. The
foregoing restrictions do not apply to applications made, to a court of competent jurisdiction or in arbitration, to enforce the terms of this Agreement.

 10.     CHOICE OF LAW AND DISPUTE RESOLUTION: This Agreement shall be
governed exclusively by and construed in accordance with the laws of the State of Connecticut without reference to its conflicts of law rules. Any controversy, dispute or claim arising out of or relating to this Agreement or the performance,
enforcement, breach, termination or validity thereof, including the determination of the scope of this arbitration provision, shall be resolved exclusively by arbitration before one arbitrator. The arbitration shall be administered by JAMS, or its
successor, pursuant to JAMS Comprehensive Arbitration Rules and Procedures, and applying the laws of the State of Connecticut. The arbitration shall be held at the JAMS hearing location nearest to Hartford, Connecticut. 

Prior to filing a demand for arbitration under this clause, a Party must request mediation through JAMS. The Parties will cooperate with JAMS and with
one another in selecting a mediator from the JAMS panel of neutrals and in scheduling the mediation proceedings. The Parties agree that they will participate in the mediation in good faith and that they will share equally in its costs. All offers,
promises, conduct and statements, whether oral or written, made in the course of the mediation by any of the Parties, their agents, employees, experts and attorneys, and by the mediator or any JAMS employees, are confidential, privileged and
inadmissible for any purpose, including impeachment, in any arbitration or other proceeding involving the Parties, provided that evidence that is otherwise admissible or discoverable shall not be rendered inadmissible or non-discoverable as a result
of its use in the mediation. Either Party may initiate arbitration with respect to the matters submitted to mediation by filing a written demand for arbitration at any time following the initial mediation session or at any time following 45 days
from the date of filing the written request for mediation, whichever occurs first (“Earliest Initiation Date”). The mediation may continue after the commencement of arbitration if the Parties so desire. All applicable statutes of
limitation and defenses based upon the passage of time shall be tolled until 15 days after the Earliest Initiation Date. The parties will take such action, if any, required to effectuate such tolling. 

In the absence of an agreement by the Parties, selection of the arbitrator shall be governed by JAMS Comprehensive Arbitration Rules and Procedures. The
compensation and expenses of the arbitrator shall initially be shared equally by the Parties. At the conclusion of the arbitration, the arbitrator shall, in good faith, approximate the extent to which each Party prevailed and shall award the costs
of the arbitration process and reasonable attorney’s fees and expenses consistent with this approximation. A Party that is determined to have fully prevailed on all its claims is entitled to all costs it incurred for the arbitration process and
all reasonable attorney’s fees and expenses. The arbitrator may not award punitive damages or consequential damages to either Party for any reason. The decision of the arbitrator shall be final, conclusive and binding, and no action at law or
in equity may be instituted by any Party other than to enforce the award of the arbitrator. The Parties intend this alternative dispute resolution procedure to be a private undertaking and agree that an arbitration conducted under this provision
will not be consolidated with an arbitration involving other healthcare providers or third parties, and that the arbitrator will be without power to conduct an arbitration on a class basis. Judgment upon the award rendered by the arbitrator may be
entered in any court of competent jurisdiction.

this Agreement is held invalid or illegal, that term shall be severed from this. Agreement and the remaining terms shall remain valid and enforceable and continue in full force and effect. No delay, omission, or failure by any Party to exercise any
right or remedy provided to it in this Agreement shall be deemed to be any waiver or acquiescence, and the Parties may exercise such right or remedy in the manner it deems expedient. Any Agreement provision that may reasonably be interpreted as
being intended by a Party to survive this Agreement’s performance, termination, or expiration shall survive any such performance, termination, or expiration.
