 SECTION 2 THE LOAN

 (a) Advances.
Subject to the terms and conditions of this Agreement, Lender will severally (and not jointly) make in an amount not to exceed its respective Term Commitment, and Borrower agrees to draw, one (1) advance in a principal amount of Twenty Million
Dollars ($20,000,000.00) on the Closing Date (the “Term A Loan Advance”). Subject to the terms and conditions of this Agreement, during the Term B Draw Period, upon Borrower’s written request in accordance with this Agreement, Lender
will severally (and not jointly) make in an amount not to exceed its respective Term Commitment, one (1) advance in a principal amount of Five Million Dollars ($5,000,000.00) (the “Term B Loan Advance”). Subject to the terms and
conditions of this Agreement, during the Term C Draw Period, upon Borrower’s written request in accordance with this Agreement, Lender will severally (and not jointly) make in an amount not to exceed its


  
 13 













 
respective Term Commitment, one (1) advance in a principal amount of Five Million Dollars ($5,000,000.00) (the “Term C Loan Advance”). The Term A Loan Advance, the Term B Loan
Advance and the Term C Loan Advance are hereinafter referred to individually as a “Term Loan Advance” and collectively as the “Term Loan Advances”. The aggregate outstanding Term Loan Advances may be up to the Maximum Term Loan
Amount. Except as otherwise set forth above, proceeds of any Term Loan Advance shall be deposited into an account that is subject to a first priority perfected security interest in favor of Agent perfected by an Account Control Agreement. 

(b) Advance Request. To obtain a Term Loan Advance, Borrower shall complete, sign and deliver to Agent an Advance Request (at least three
(3) Business Days before the Advance Date, other than the Term A Loan Advance, which shall be at least one (1) Business Day) to Agent. Lender shall fund the Term Loan Advance in the manner requested by the Advance Request provided that
each of the conditions precedent to such Term Loan Advance is satisfied as of the requested Advance Date. 
 (c) Interest. The principal
balance of each Term Loan Advance shall bear interest thereon from such Advance Date at the Term Loan Interest Rate based on a year consisting of three hundred sixty (360) days, with interest computed daily based on the actual number of days
elapsed. The Term Loan Interest Rate will float and change on the day the Prime Rate changes from time to time. 
 (d) Payment. Borrower will
pay interest on each Term Loan Advance on the first (1st) Business Day of each month, beginning the month after the Advance Date. Borrower shall repay the aggregate Term Loan principal balance
that is outstanding on the day immediately preceding the Amortization Date, in equal monthly installments of principal and interest (mortgage style) beginning on the Amortization Date and continuing on the first Business Day of each month thereafter
until the Secured Obligations (other than inchoate indemnity obligations) are repaid. The entire Term Loan principal balance and all accrued but unpaid interest hereunder, and all other Secured Obligations with respect to the Term Loan Advances,
shall be due and payable on Term Loan Maturity Date. Borrower shall make all payments under this Agreement without setoff, recoupment or deduction and regardless of any counterclaim or defense. Lender will initiate debit entries to the
Borrower’s account as authorized on the ACH Authorization (i) on each payment date of all periodic obligations payable to Lender under each Term Advance and
(ii) out-of-pocket legal fees and costs incurred by Agent or Lender in connection with Section 11.11 of this Agreement; provided that, with respect to clause
(i) above, in the event that Lender or Agent informs Borrower that Lender will not initiate a debit entry to Borrower’s account for a certain amount of the periodic obligations due on a specific payment date, Borrower shall pay to Lender
such amount of periodic obligations in full in immediately available funds on such payment date; provided, further, that, with respect to clause (i) above, if Lender or Agent informs Borrower that Lender will not initiate a debit entry as
described above later than the date that is three (3) Business Days prior to such payment date, Borrower shall pay to Lender such amount of periodic obligations in full in immediately available funds on the date that is three (3) Business
Days after the date on which Lender or Agent notifies Borrower of such; provided, further, that, with respect to clause (ii) above, in the event that Lender or Agent informs Borrower that Lender will not initiate a debit entry to
Borrower’s account for certain amount of such out-of-pocket legal fees and costs incurred by Agent or Lender, Borrower shall pay to Lender such amount in full in
immediately available funds within three (3) Business Days. Once repaid, a Term Loan Advance or any portion thereof may not be reborrowed. 

  
 14 













 2.2 Maximum Interest. Notwithstanding any provision in this Agreement or any other Loan
Document, it is the parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that a court of competent jurisdiction shall deem applicable hereto (which under the laws of
the State of California shall be deemed to be the laws relating to permissible rates of interest on commercial loans) (the “Maximum Rate”). If a court of competent jurisdiction shall finally determine that Borrower has actually paid to
Lender an amount of interest in excess of the amount that would have been payable if all of the Secured Obligations had at all times borne interest at the Maximum Rate, then such excess interest actually paid by Borrower shall be applied as follows:
first, to the payment of the Secured Obligations consisting of the outstanding principal; second, after all principal is repaid, to the payment of Lender’s accrued interest, costs, expenses, professional fees and any other Secured Obligations;
and third, after all Secured Obligations are repaid, the excess (if any) shall be refunded to Borrower. 
 2.3 Default Interest. In the event
any payment is not paid on the scheduled payment date, an amount equal to four percent (4.0%) of the past due amount shall be payable on demand. In addition, upon the occurrence and during the continuation of an Event of Default hereunder, all
Secured Obligations, including principal, interest, compounded interest, and professional fees, shall bear interest at a rate per annum equal to the rate set forth in Section 2.1(c), plus four percent (4.0%) per annum. In the event any interest
is not paid when due hereunder, delinquent interest shall be added to principal and shall bear interest on interest, compounded at the rate set forth in Section 2.1(c) or Section 2.4, as applicable. 

2.4 Prepayment. At its option upon at least seven (7) Business Days prior written notice to Agent, Borrower may prepay all, but not less
than all, of the outstanding Advances by paying the entire principal balance, and all accrued and unpaid interest thereon, together with a prepayment charge equal to the following percentage of the Advance amount being prepaid: if such Advance
amounts are prepaid in any of the first twelve (12) months following the Closing Date, three percent (3.0%); after twelve (12) months but prior to twenty four (24) months, two percent (2.0%); and thereafter, one percent (1.0%) (each,
a “Prepayment Charge”). Borrower agrees that the Prepayment Charge is a reasonable calculation of Lender’s lost profits in view of the difficulties and impracticality of determining actual damages resulting from an early repayment of
the Advances. Borrower shall prepay the outstanding amount of all principal and accrued interest through the prepayment date and the Prepayment Charge upon the occurrence of a Change in Control. Notwithstanding the foregoing, Agent and Lender agree
to waive the Prepayment Charge if Agent and Lender (each in its sole and absolute discretion) agree in writing to refinance the Advances prior to the Maturity Date. Further, notwithstanding anything to the contrary contained herein, the Prepayment
Charge shall be automatically waived upon any assignment of the Loan, this Agreement and the other Loan Documents pursuant to Section 11.13 hereof by a Lender or the Agent (other than any assignment to an Affiliate of any Lender or Agent or any
assignment made for securitization purposes). 

  
 15 













 2.5 End of Term Charge. On the earliest to occur of (i) the Term Loan Maturity Date,
(ii) the date that Borrower prepays the outstanding Secured Obligations (other than any inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) in full, or (iii) the
date that the Secured Obligations become due and payable, Borrower shall pay Lender a charge equal to the End of Term Charge. Notwithstanding the required payment date of such charge, it shall be deemed earned by Lender as of the Closing Date. 

2.6 Notes. If so requested by Lender by written notice to Borrower, then Borrower shall execute and deliver to Lender (and/or, if applicable
and if so specified in such notice, to any Person who is an assignee of Lender pursuant to Section 11.13) (promptly after the Borrower’s receipt of such notice) a Note or Notes to evidence Lender’s Loans. 

2.7 Pro Rata Treatment. Each payment (including prepayment) on account of any fee and any reduction of the Term Loan Advances shall be made pro
rata according to the Term Commitments of the relevant Lender. 
 SECTION 3 SECURITY INTEREST 

3.1 As security for the prompt and complete payment when due (whether on the payment dates or otherwise) of all the Secured Obligations,
Borrower grants to Agent a security interest in all of Borrower’s right, title, and interest in, to and under all of Borrower’s personal property and other assets including without limitation the following (except as set forth herein)

prohibition on transfer is enforceable under applicable law including, without limitation, Sections 9-406, 9-407, 9-408 and 9-409 of the UCC), (c) property owned by Borrower that is subject to a purchase money Lien or a capital lease (and the proceeds thereof) permitted under this Agreement if the contractual obligation pursuant to which
such Lien is granted (or in the document providing for such capital lease) prohibits or requires the consent of any person other than Borrower which has not been obtained as a condition to the creation of, any other Lien on such property, or
(d) any (i) accounts used solely to fund current payroll or employee benefits maintained in the ordinary course of business, (ii) escrow and Cash collateral accounts properly owned by commercial insurance partners of Borrower or lessors to
Borrower maintained in the ordinary course of business, or (iii) so long as the proceeds of such account are transferred on a daily basis to an account in which Agent has a security interest and that is subject to an Account Control Agreement,
accounts maintained in the ordinary course of business (A) solely containing payments from commercial insurance partners of Borrower or the Centers for Medicare and Medicaid Services, and (B) that are subject to a written agreement between
Borrower and commercial insurance partners of Borrower or the Centers for Medicare and Medicaid Services that contains a prohibition on granting a security interest to Agent that is effective under applicable law.

required hereunder, Borrower shall provide Agent with copies of such policies and shall promptly deliver to Agent updated insurance certificates with respect to such policies.

Collateral, excluding in all cases Liabilities to the extent resulting solely from any Indemnified Person’s gross negligence or willful misconduct. Borrower agrees to pay, and to save Agent and Lender harmless from, any and all liabilities with
respect to, or resulting from any delay in paying, any and all excise, sales or other similar taxes (excluding taxes imposed on or measured by the net income of Agent or Lender) that may be payable or determined to be payable with respect to any of

“all assets or all personal property” of Borrower in accordance with Section 9-504 of the UCC), collateral assignments, notices, control agreements, security agreements and other documents
without the signature of Borrower either in Agent’s name or in the name of Agent as agent and attorney-in-fact for Borrower. Borrower shall protect and defend

Borrower’s business or in which Borrower now or hereafter holds any interest free and clear from any legal process or Liens whatsoever (except for Permitted Liens), and shall give Agent prompt written notice of any legal process affecting the
Collateral, such other property and assets, or any Liens thereon, provided however, that the Collateral and such other property and assets may be subject to Permitted Liens except that there shall be no Liens whatsoever on Intellectual Property.

agreement that prohibits or limits the ability of any Borrower to create, incur, assume or suffer to exist any Lien upon any of its Intellectual Property, whether now owned or hereafter acquired,
to secure its obligations under the Loan Documents to which it is a party other than (a) this Agreement and the other Loan Documents, (b) any agreements governing any purchase money Liens or capital lease obligations otherwise permitted
hereby (in which case, any prohibition or limitation shall only be effective against the assets financed thereby) and (c) customary restrictions on the assignment of leases, licenses and other agreements. Borrower shall cause its Subsidiaries
to protect and defend such Subsidiary’s title to its assets from and against all Persons claiming any interest adverse to such Subsidiary, and Borrower shall cause its Subsidiaries at all times to keep such Subsidiary’s property and assets

Loan Documents or otherwise available to it under the UCC and other applicable law, including the right to release, hold, sell, lease, liquidate, collect, realize upon, or otherwise dispose of all or any part of the Collateral and the right to
occupy, utilize, process and commingle the Collateral. All Agent’s rights and remedies shall be cumulative and not exclusive. 

  
 31 













 10.2 Collection; Foreclosure. Upon the occurrence and during the continuance of any Event of
Default, Agent may, and at the direction of the Required Lenders shall, at any time or from time to time, apply, collect, liquidate, sell in one or more sales, lease or otherwise dispose of, any or all of the Collateral, in its then condition or
following any commercially reasonable preparation or processing, in such order as Agent may elect. Any such sale may be made either at public or private sale at its place of business or elsewhere. Borrower agrees that any such public or private sale
may occur upon ten (10) calendar days’ prior written notice to Borrower. Agent may require Borrower to assemble the Collateral and make it available to Agent at a place designated by Agent that is reasonably convenient to Agent and
Borrower. The proceeds of any sale, disposition or other realization upon all or any part of the Collateral shall be applied by Agent in the following order of priorities: 

First, to Agent and Lender in an amount sufficient to pay in full Agent’s and Lender’s reasonable costs and professionals’ and
advisors’ fees and expenses as described in Section 11.11; 
 Second, to Lender in an amount equal to the then unpaid amount of the
Secured Obligations (including principal, interest, and the Default Rate interest), in such order and priority as Agent may choose in its sole discretion; and 

Finally, after the full and final payment in Cash of all of the Secured Obligations (other than inchoate obligations), to any creditor holding
a junior Lien on the Collateral, or to Borrower or its representatives or as a court of competent jurisdiction may direct. 
 Agent shall be deemed to have
acted reasonably in the custody, preservation and disposition of any of the Collateral if it complies with the obligations of a secured party under the UCC. 

10.3 No Waiver. Agent shall be under no obligation to marshal any of the Collateral for the benefit of Borrower or any other Person, and
Borrower expressly waives all rights, if any, to require Agent to marshal any Collateral. 
 10.4 Cumulative Remedies. The rights, powers and
remedies of Agent hereunder shall be in addition to all rights, powers and remedies given by statute or rule of law and are cumulative. The exercise of any one or more of the rights, powers and remedies provided herein shall not be construed as a
waiver of or election of remedies with respect to any other rights, powers and remedies of Agent. 
 SECTION 11 MISCELLANEOUS 

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

11.3 Entire Agreement; Amendments. 

(a) This Agreement and the other Loan Documents constitute the entire agreement and understanding of the parties hereto in respect of the
subject matter hereof and thereof, and supersede and replace in their entirety any prior proposals, term sheets, non-disclosure or confidentiality agreements, letters, negotiations or other documents or
agreements, whether written or oral, with respect to the subject matter hereof or thereof (including Agent’s revised proposal letter dated June 30, 2017 and the Non-Disclosure Agreement). 

(b) Neither this Agreement, any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in
accordance with the provisions of this Section 11.3(b). The Required Lenders and Borrower party to the relevant Loan Document may, or, with the written consent of the Required Lenders, the Agent and the Borrower party to the relevant Loan
Document may, from time to time, (i) enter into written amendments, supplements or modifications hereto and to the other Loan Documents for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any
manner the rights of the Lenders or of the Borrower hereunder or thereunder or (ii) waive, on such terms and conditions as the Required Lenders or the Agent, as the case may be, may specify in such


  
 33 













 
instrument, any of the requirements of this Agreement or the other Loan Documents or any default or Event of Default and its consequences; provided, however, that no such waiver and no such
amendment, supplement or modification shall (A) forgive the principal amount or extend the final scheduled date of maturity of any Loan, extend the scheduled date of any amortization payment in respect of any Term Loan Advance, reduce the
stated rate of any interest or fee payable hereunder or extend the scheduled date of any payment thereof, in each case without the written consent of each Lender directly affected thereby; (B) eliminate or reduce the voting rights of any Lender
under this Section 11.3(b) without the written consent of such Lender; (C) reduce any percentage specified in the definition of Required Lenders, consent to the assignment or transfer by the Borrower of any of its rights and obligations
under this Agreement and the other Loan Documents, release all or substantially all of the Collateral or release a Borrower from its obligations under the Loan Documents, in each case without the written consent of all Lenders; or (D) amend,
modify or waive any provision of Section 11.17 without the written consent of the Agent. Any such waiver and any such amendment, supplement or modification shall apply equally to each Lender and shall be binding upon Borrower, the Lender, the
Agent and all future holders of the Loans. 
 11.4 No Strict Construction. The parties hereto have participated jointly in the negotiation
and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or
disfavoring any party by virtue of the authorship of any provisions of this Agreement. 
 11.5 No Waiver. The powers conferred upon Agent and
Lender by this Agreement are solely to protect its rights hereunder and under the other Loan Documents and its interest in the Collateral and shall not impose any duty upon Agent or Lender to exercise any such powers. No omission or delay by Agent
or Lender at any time to enforce any right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by Borrower at any time designated, shall be a waiver of any such right or remedy to which Agent or
Lender is entitled, nor shall it in any way affect the right of Agent or Lender to enforce such provisions thereafter. 
 11.6 Termination
Prior to Term Loan Maturity Date; Survival. All agreements, representations and warranties contained in this Agreement and the other Loan Documents or in any document delivered pursuant hereto or thereto shall be for the benefit of Agent and Lender
and shall survive the execution and delivery of this Agreement. All covenants, representations and warranties made in this Agreement shall continue in full force until this Agreement has terminated pursuant to its terms and all Secured Obligations
(excluding any obligations pursuant to Section 6.3 or Section 8.1) have been satisfied. So long as Borrower has satisfied the Secured Obligations (other obligations under Section 6.3 or Section 8.1), this Agreement may be
terminated prior to the Term Loan Maturity Date by Borrower, effective three (3) Business Days after written notice of termination is given to Agent. Sections 6.3 and 8.1 shall survive the termination of this Agreement. 

11.7 Successors and Assigns. The provisions of this Agreement and the other Loan Documents shall inure to the benefit of and be binding on
Borrower and its permitted assigns (if any). Borrower shall not assign its obligations under this Agreement or any of the other Loan Documents without Agent’s express prior written consent, and any such attempted assignment shall be void and of
no effect. Agent and Lender may assign, transfer, or endorse its rights 

  
 34 













 
hereunder and under the other Loan Documents without prior notice to Borrower, and all of such rights shall inure to the benefit of Agent’s and Lender’s successors and assigns; provided
that as long as no Event of Default has occurred and is continuing, neither Agent nor any Lender may assign, transfer or endorse its rights hereunder or under the Loan Documents to any party that is a direct competitor of Borrower (as reasonably
determined by Agent), it being acknowledged that in all cases, any transfer to an Affiliate of any Lender or Agent shall be allowed. 
 11.8
Governing Law. This Agreement and the other Loan Documents have been negotiated and delivered to Agent and Lender in the State of California, and shall have been accepted by Agent and Lender in the State of California. Payment to Agent and Lender by
Borrower of the Secured Obligations is due in the State of California. This Agreement and the other Loan Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of California, excluding conflict of laws
principles that would cause the application of laws of any other jurisdiction. 
 11.9 Consent to Jurisdiction and Venue. All judicial
proceedings (to the extent that the reference requirement of Section 11.10 is not applicable) arising in or under or related to this Agreement or any of the other Loan Documents may be brought in any state or federal court located in the State
of California. By execution and delivery of this Agreement, each party hereto generally and unconditionally: (a) consents to nonexclusive personal jurisdiction in Santa Clara County, State of California; (b) waives any objection as to
jurisdiction or venue in Santa Clara County, State of California; (c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (d) irrevocably agrees to be bound by any judgment rendered thereby
in connection with this Agreement or the other Loan Documents. Service of process on any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance with the requirements for notice set forth in
Section 11.2, and shall be deemed effective and received as set forth in Section 11.2. Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either party to bring
proceedings in the courts of any other jurisdiction. 
 11.10 Mutual Waiver of Jury Trial / Judicial Reference. 

(a) Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an experienced and
expert Person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF BORROWER, AGENT AND LENDER
SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY BORROWER AGAINST AGENT, LENDER OR THEIR
RESPECTIVE ASSIGNEE OR BY AGENT, LENDER OR THEIR RESPECTIVE ASSIGNEE AGAINST BORROWER. This waiver extends to all such Claims, including Claims that involve Persons other than Agent, Borrower and Lender; Claims that arise out of or are in any way
connected to the relationship among Borrower, Agent and Lender; and any Claims for damages, breach of contract, tort, specific performance, or any equitable or legal relief of any kind, arising out of this Agreement, any other Loan Document. 

  
 35 













 (b) If the waiver of jury trial set forth in Section 11.10(a) is ineffective or
unenforceable, the parties agree that all Claims shall be resolved by reference to a private judge sitting without a jury, pursuant to Code of Civil Procedure Section 638, before a mutually acceptable referee or, if the parties cannot agree, a
referee selected by the Presiding Judge of the Santa Clara County, California. Such proceeding shall be conducted in Santa Clara County, California, with California rules of evidence and discovery applicable to such proceeding. 

(c) In the event Claims are to be resolved by judicial reference, either party may seek from a court identified in Section 11.9, any
prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to resolution by judicial reference. 

11.11 Professional Fees. Borrower promises to pay Agent’s and Lender’s reasonable and documented fees and expenses necessary to
finalize the loan documentation, including but not limited to reasonable and documented attorneys fees, UCC searches, filing costs, and other miscellaneous expenses. In addition, Borrower promises to pay any and all reasonable and documented
attorneys’ and other professionals’ fees and expenses incurred by Agent and Lender after the Closing Date in connection with or related to: (a) the Loan; (b) the administration, collection, or enforcement of the Loan;
(c) the amendment or modification of the Loan Documents; (d) any waiver, consent, release, or termination under the Loan Documents; (e) the protection, preservation, audit, field exam, sale, lease, liquidation, or disposition of
Collateral or the exercise of remedies with respect to the Collateral; (1) any legal, litigation, administrative, arbitration, or out of court proceeding in connection with or related to Borrower or the Collateral, and any appeal or review
thereof arising from or in connection with this Agreement or the other Loan Documents; and (g) any bankruptcy, restructuring, reorganization, assignment for the benefit of creditors, workout, foreclosure, or other action related to Borrower,
the Collateral, the Loan Documents, including representing Agent or Lender in any adversary proceeding or contested matter commenced or continued by or on behalf of Borrower’s estate, and any appeal or review thereof. 

11.12 Confidentiality. Agent and Lender acknowledge that certain items of Collateral and information provided to Agent and Lender by Borrower
are confidential and proprietary information of Borrower, if and to the extent such information either (x) is marked as confidential by Borrower at the time of disclosure, or (y) should reasonably be understood to be confidential (the
“Confidential Information”). Accordingly, Agent and Lender agree that any Confidential Information it may obtain in the course of acquiring, administering, or perfecting Agent’s security interest in the Collateral shall not be
disclosed to any other Person or entity in any manner whatsoever, in whole or in part, without the prior written consent of Borrower, except that Agent and Lender may disclose any such information: (a) to its own directors, officers, employees,
accountants, counsel and other professional advisors and to its Affiliates if Agent or Lender in their sole discretion determines that any such party should have access to such information in connection with such party’s responsibilities in
connection with the Loan or this Agreement and, provided that such recipient of such Confidential Information either (i) agrees to be bound by the confidentiality provisions of this paragraph or (ii) is otherwise subject to confidentiality
restrictions that reasonably protect against the disclosure of Confidential Information; (b) if such information is generally available to the public; (c) if required or appropriate in any report, statement or testimony submitted to any
governmental authority having or claiming to have jurisdiction over Agent or Lender; (d) if required or appropriate in response to any summons or 

  
 36 













 
subpoena or in connection with any litigation, to the extent permitted or deemed advisable by Agent’s or Lender’s counsel; (e) to comply with any legal requirement or law
applicable to Agent or Lender; (f) to the extent reasonably necessary in connection with the exercise of any right or remedy under any Loan Document, including Agent’s sale, lease, or other disposition of Collateral after default;
(g) to any participant or assignee of Agent or Lender or any prospective participant or assignee; provided, that such participant or assignee or prospective participant or assignee agrees in writing to be bound by this Section prior to
disclosure; or (h) otherwise with the prior consent of Borrower; provided, that any disclosure made in violation of this Agreement shall not affect the obligations of Borrower or any of its Affiliates or any guarantor under this Agreement or
the other Loan Documents. Agent’s and Lender’s obligations under this Section 11.12 shall supersede and replace all of their respective obligations under the Non-Disclosure Agreement. 

11.13 Assignment of Rights. Borrower acknowledges and understands that Agent or Lender may, subject to Section 11.7, sell and assign all
or part of its interest hereunder and under the Loan Documents to any Person or entity (an “Assignee”), provided that as long as no Event of Default has occurred and is continuing, neither Agent nor any Lender may assign, transfer or
endorse its rights hereunder or under the Loan Documents to any party that is a direct competitor of Borrower (as reasonably determined by Agent), it being acknowledged that in all cases, any transfer to an Affiliate of any Lender or Agent shall be
allowed, provided that no assignment (other than to an Affiliate of any Lender or Agent or any assignment for securitization purposes) shall be effective until such time as Borrower is provided fifteen (15) days prior written notice thereof.
After such assignment the term “Agent” or “Lender” as used in the Loan Documents shall mean and include such Assignee, and such Assignee shall be vested with all rights, powers and remedies of Agent and Lender hereunder with
respect to the interest so assigned; but with respect to any such interest not so transferred, Agent and Lender shall retain all rights, powers and remedies hereby given. No such assignment by Agent or Lender shall relieve Borrower of any of its
obligations hereunder. Lender agrees that in the event of any transfer by it of the Note(s)(if any), it will endorse thereon a notation as to the portion of the principal of the Note(s), which shall have been paid at the time of such transfer and as
to the date to which interest shall have been last paid thereon. 
 11.14 Revival of Secured Obligations. This Agreement and the Loan
Documents shall remain in full force and effect and continue to be effective if any petition is filed by or against Borrower for liquidation or reorganization, if Borrower becomes insolvent or makes an assignment for the benefit of creditors, if a
receiver or trustee is appointed for all or any significant part of Borrower’s assets, or if any payment or transfer of Collateral is recovered from Agent or Lender. The Loan Documents and the Secured Obligations and Collateral security shall
continue to be effective, or shall be revived or reinstated, as the case may be, if at any time payment and performance of the Secured Obligations or any transfer of Collateral to Agent, or any part thereof is rescinded, avoided or avoidable,
reduced in amount, or must otherwise be restored or returned by, or is recovered from, Agent, Lender or by any obligee of the Secured Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as
though such payment, performance, or transfer of Collateral had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, avoided, avoidable, restored, returned, or recovered, the Loan Documents and the Secured
Obligations shall be deemed, without any further action or documentation, to have been revived and reinstated except to the extent of the full, final, and indefeasible payment to Agent or Lender in Cash. 

  
 37 













 11.15 Counterparts. This Agreement and any amendments, waivers, consents or supplements
hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same
instrument. 
 11.16 No Third Party Beneficiaries. No provisions of the Loan Documents are intended, nor will be interpreted, to provide or
create any third-party beneficiary rights or any other rights of any kind in any Person other than Agent, Lender and Borrower unless specifically provided otherwise herein, and, except as otherwise so provided, all provisions of the Loan Documents
will be personal and solely among Agent, the Lender and the Borrower. 
 11.17 Agency. 

(a) Lender hereby irrevocably appoints Hercules Capital, Inc. to act on its behalf as the Agent hereunder and under the other Loan Documents
and authorizes the Agent to take such actions on its behalf and to exercise such powers as are delegated to the Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. 

(b) Lender agrees to indemnify the Agent in its capacity as such (to the extent not reimbursed by Borrower and without limiting the obligation
of Borrower to do so), according to its respective Term Commitment percentages (based upon the total outstanding Term Commitments) in effect on the date on which indemnification is sought under this Section 11.17, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time be imposed on, incurred by or asserted against the Agent in any way relating to or arising
out of, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Agent under or in connection with any
of the foregoing; The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder. 
 (c) Agent
in Its Individual Capacity. The Person serving as the Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Agent and the term “Lender”
shall, unless otherwise expressly indicated or unless the context otherwise requires, include each such Person serving as Agent hereunder in its individual capacity. 

(d) Exculpatory Provisions. The Agent shall have no duties or obligations except those expressly set forth herein and in the other Loan
Documents. Without limiting the generality of the foregoing, the Agent shall not: 
  

	 	(i)	 be subject to any fiduciary or other implied duties, regardless of whether any Default or any Event of Default
has occurred and is continuing; 


  

	 	(ii)	 have any duty to take any discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated hereby or by the other Loan Documents that the Agent is required to exercise as directed in writing by the Lender, 



  
 38 














	 	
provided that the Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is contrary to any Loan Document or
applicable law; and 

  

	 	(iii)	 except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and the Agent
shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by any Person serving as the Agent or any of its Affiliates in any capacity.



 (e) The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of
the Lender or as the Agent shall believe in good faith shall be necessary, under the circumstances or (ii) in the absence of its own gross negligence or willful misconduct. 

(f) The Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation
made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, the performance or observance of
any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan
Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Section 4 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Agent. 

(g) Reliance by Agent. Agent may rely, and shall be fully protected in acting, or refraining to act, upon, any resolution, statement,
certificate, instrument, opinion, report, notice, request, consent, order, bond or other paper or document that it has no reason to believe to be other than genuine and to have been signed or presented by the proper party or parties or, in the case
of cables, telecopies and telexes, to have been sent by the proper party or parties. In the absence of its gross negligence or willful misconduct, Agent may conclusively rely, as to the truth of the statements and the correctness of the opinions
expressed therein, upon any certificates or opinions furnished to Agent and conforming to the requirements of the Loan Agreement or any of the other Loan Documents. Agent may consult with counsel, and any opinion or legal advice of such counsel
shall be full and complete authorization and protection in respect of any action taken, not taken or suffered by Agent hereunder or under any Loan Documents in accordance therewith. Agent shall have the right at any time to seek instructions
concerning the administration of the Collateral from any court of competent jurisdiction. Agent shall not be under any obligation to exercise any of the rights or powers granted to Agent by this Agreement, the Loan Agreement and the other Loan
Documents at the request or direction of Lenders unless Agent shall have been provided by Lender with adequate security and indemnity against the costs, expenses and liabilities that may be incurred by it in compliance with such request or
direction.

Affiliates shall, without the other parties’ prior written consent (which shall not be unreasonably withheld or delayed), publicize or use (a) the other party’s name (including a brief description of the relationship among the parties
hereto), logo or hyperlink to such other parties’ web site, separately or together, in written and oral presentations, advertising, promotional and marketing materials, client lists, public relations materials or on its web site (together, the
“ Publicity Materials”); (b) the names of officers of such other parties in the Publicity Materials; and (c) such other parties’ name, trademarks, servicemarks in any news or press release concerning such party; provided however,

with any national securities exchange (so long as such party provides prior notice to the other party hereto to the extent reasonably practicable) and (ii) to comply with Section 11.12. 

11.19 Multiple Borrowers. 
 (a)
Borrower’s Agent. Each of the Borrowers hereby irrevocably appoints Oak Street Health MSO as its agent, attorney-in-fact and legal representative for all purposes,
including requesting disbursement of the Term Loan and receiving account statements and other notices and communications to Borrowers (or any of them) from the Agent or any Lender. The Agent may rely, and shall be fully protected in relying, on any
request for the Term Loan, disbursement instruction, report, information or any other notice or communication made or given by Oak Street Health MSO, whether in its own name or on behalf of one or more of the other Borrowers, and the Agent shall not
have any obligation to make any inquiry or request any confirmation from or on behalf of any other Borrower as to the binding effect on it of any such request, instruction, report, information, other notice or communication, nor shall the joint and
several character of the Borrowers’ obligations hereunder be affected thereby. 
 (b) Waivers. Each Borrower hereby waives: (i) any
right to require the Agent to institute suit against, or to exhaust its rights and remedies against, any other Borrower or any other person, or to proceed against any property of any kind which secures all or any part of the Secured Obligations, or
to exercise any right of offset or other right with respect to any reserves, credits or deposit accounts held by or maintained with the Agent or any Indebtedness of the Agent or any Lender to any other Borrower, or to exercise any other right or
power, or pursue any other remedy the Agent or any Lender may have; (ii) any defense arising by reason of any disability or other defense of any other Borrower or any guarantor or any endorser, co-maker
or other person, or by reason of the cessation from any cause whatsoever of any liability of any other Borrower or any guarantor or any endorser, co-maker or other person, with respect to all or any part of
the Secured Obligations, or by reason of any act or omission of the Agent or others which directly or indirectly results in the discharge or release of any other Borrower or any guarantor or any other person or any Secured Obligations or any
security therefor, whether by operation of law or otherwise; (iii) any defense arising by reason of any failure of the Agent to obtain, perfect, maintain or keep in force any Lien on, any property of any Borrower or any other person;
(iv) any defense based upon or arising out of any bankruptcy, insolvency, reorganization, arrangement, readjustment of debt, liquidation or dissolution proceeding commenced by or against any other Borrower or any guarantor or any endorser, co-maker or other person, including without limitation any discharge of, or bar against collecting, any of the Secured Obligations (including without limitation any interest thereon), in or as a result of any such
proceeding. Until all of the Secured Obligations have been paid, performed, and discharged in full, nothing shall discharge or satisfy the liability of any Borrower hereunder except the full performance and payment of all of the


  
 40 













 
Secured Obligations. If any claim is ever made upon the Agent for repayment or recovery of any amount or amounts received by the Agent in payment of or on account of any of the Secured
Obligations, because of any claim that any such payment constituted a preferential transfer or fraudulent conveyance, or for any other reason whatsoever, and the Agent repays all or part of said amount by reason of any judgment, decree or order of
any court or administrative body having jurisdiction over the Agent or any of its property, or by reason of any settlement or compromise of any such claim effected by the Agent with any such claimant (including without limitation the any other
Borrower), then and in any such event, each Borrower agrees that any such judgment, decree, order, settlement and compromise shall be binding upon such Borrower, notwithstanding any revocation or release of this Agreement or the cancellation of any
note or other instrument evidencing any of the Secured Obligations, or any release of any of the Secured Obligations, and each Borrower shall be and remain liable to the Agent and the Lenders under this Agreement for the amount so repaid or
recovered, to the same extent as if such amount had never originally been received by the Agent or any Lender, and the provisions of this sentence shall survive, and continue in effect, notwithstanding any revocation or release of this Agreement.
Each Borrower hereby expressly and unconditionally waives all rights of subrogation, reimbursement and indemnity of every kind against any other Borrower, and all rights of recourse to any assets or property of any other Borrower, and all rights to
any collateral or security held for the payment and performance of any Secured Obligations, including (but not limited to) any of the foregoing rights which Borrower may have under any present or future document or agreement with any other Borrower
or other person, and including (but not limited to) any of the foregoing rights which any Borrower may have under any equitable doctrine of subrogation, implied contract, or unjust enrichment, or any other equitable or legal. doctrine. 

(c) Consents. Each Borrower hereby consents and agrees that, without notice to or by Borrower and without affecting or impairing in any way the
obligations or liability of Borrower hereunder, the Agent may, from time to time before or after revocation of this Agreement, do any one or more of the following in its sole and absolute discretion: (1) accept partial payments of, compromise
or settle, renew, extend the time for the payment, discharge, or performance of, refuse to enforce, and release all or any parties to, any or all of the Secured Obligations; (ii) grant any other indulgence to any Borrower or any other Person in
respect of any or all of the Secured Obligations or any other matter; (iii) accept, release, waive, surrender, enforce, exchange, modify, impair, or extend the time for the performance, discharge, or payment of, any and all property of any kind
securing any or all of the Secured Obligations or any guaranty of any or all of the Secured Obligations, or on which the Agent at any time may have a Lien, or refuse to enforce its rights or make any compromise or settlement or agreement therefor in
respect of any or all of such property; (iv) substitute or add, or take any action or omit to take any action which results in the release of, any one or more other Borrowers or any endorsers or guarantors of all or any part of the Secured

Agreement (the “Joinder Agreement”) is made and dated as of [    ], 20[    ] and is entered into by and between
                    , a             
             (“Subsidiary”), and HERCULES CAPITAL, INC., a Maryland corporation (as “Agent”). 

RECITALS 
 A.
Subsidiary’s Affiliate, (i) OAK STREET HEALTH, LLC, an Illinois limited liability company (“Oak Street Health”), (ii) OAK STREET HEALTH MSO, LLC, an Illinois limited liability company (“Oak Street Health MSO”), (iii)
ACORN NETWORK, LLC, an Illinois limited liability company (“Acorn Network”), (iv) OAK STREET HEALTH PHYSICIANS GROUP, P.C., an Illinois professional corporation (“OSH Physicians”), (v)

Michigan professional corporation (“OSH-MI”), (vii) OSH-IN PHYSICIANS GROUP, PC, an Indiana professional corporation
(“OSH-IN”), and (viii) each of the Qualified Subsidiaries and Physician’s Groups of any of the foregoing (the “Additional Borrowers”; and together with Oak Street Health, Oak
Street Health MSO, Acorn Network, OSH Physicians, OSH-IL, OSH-MI and OSH-IN, jointly and severally, individually and
collectively, the “Company”) has entered into that certain Loan and Security Agreement dated August 7, 2017, with the several banks and other financial institutions or entities from time to time party thereto as lender (collectively,
the “Lender”) and the Agent, as such agreement may be amended, supplemented, replaced, restated, amended and restated or otherwise modified from time to time (the “Loan Agreement”), together with the other agreements executed and
delivered in connection therewith; 
 B. Subsidiary acknowledges and agrees that it will benefit both directly and indirectly from
Company’s execution of the Loan Agreement and the other agreements executed and delivered in connection therewith; 
 AGREEMENT

 NOW THEREFORE, Subsidiary and Agent agree as follows: 
  

	1.	 The recitals set forth above are incorporated into and made part of this Joinder Agreement. Capitalized terms
not defined herein shall have the meaning provided in the Loan Agreement. 


  

	2.	 By signing this Joinder Agreement, Subsidiary shall be bound by the terms and conditions of the Loan Agreement
the same as if it were the Borrower (as defined in the Loan Agreement) under the Loan Agreement, mutatis mutandis, provided however, that (a) with respect to (i) Section 5.1 of the Loan Agreement, Subsidiary represents that it is an
entity duly organized, legally existing and in good standing under the laws of [                ], (b) neither Agent nor Lender shall have any duties, responsibilities
or obligations to Subsidiary arising under or related to the Loan Agreement or the other Loan Documents, (c) that if Subsidiary is covered by Company’s insurance, Subsidiary shall not be required to maintain separate
















	 	
insurance or comply with the provisions of Sections 6.1 and 6.2 of the Loan Agreement, and (d) that as long as Company satisfies the requirements of Section 7.1 of the Loan Agreement,
Subsidiary shall not have to provide Agent separate Financial Statements. To the extent that Agent or Lender has any duties, responsibilities or obligations arising under or related to the Loan Agreement or the other Loan Documents, those duties,
responsibilities or obligations shall flow only to Company and not to Subsidiary or any other Person or entity. By way of example (and not an exclusive list): (i) Agent’s providing notice to Company in accordance with the Loan Agreement or as
otherwise agreed among Company, Agent and Lender shall be deemed provided to Subsidiary; (ii) a Lender’s providing an Advance to Company shall be deemed an Advance to Subsidiary; and (iii) Subsidiary shall have no right to request an
Advance or make any other demand on Lender. 

  

	3.	 Subsidiary agrees not to certificate its equity securities without Agent’s prior written consent, which
consent may be conditioned on the delivery of such equity securities to Agent in order to perfect Agent’s security interest in such equity securities. 


  

	4.	 Subsidiary acknowledges that it benefits, both directly and indirectly, from the Loan Agreement, and hereby
waives, for itself and on behalf of any and all successors in interest (including without limitation any assignee for the benefit of creditors, receiver, bankruptcy trustee or itself as debtor-in-possession
under any bankruptcy proceeding) to the fullest extent provided by law, any and all claims, rights or defenses to the enforcement of this Joinder Agreement on the basis that (a) it failed to receive adequate consideration for the execution and
delivery of this Joinder Agreement or (b) its obligations under this Joinder Agreement are avoidable as a fraudulent conveyance. 


  

	5.	 As security for the prompt, complete and indefeasible payment when due (whether on the payment dates or
otherwise) of all the Secured Obligations, Subsidiary grants to Agent a security interest in all of Subsidiary’s right, title, and interest in and to the Collateral.
