Advance”), in accordance with each Lender’s Pro Rata Share of such Advance, up to an aggregate maximum amount of Subsequent Advances of $37,500,000. Notwithstanding the foregoing, to the extent that as of any Funding Request Notice
Date (as defined in Section 2.5 below) the Company has filed (and not withdrawn) a registration statement on Form S-1 (or any successor or similar form) with the Securities and Exchange Commission for a public offering of securities, the
Company may at its discretion limit participation in the Subsequent Advances to the Lenders set forth on Schedule I-A. In such event, the non-participating Lenders shall be deemed to have waived any right to participate in such Subsequent
Advance. In the event that participation in the Subsequent Advance is limited to the Lenders on Schedule I-A, such Lenders may in their sole discretion fund, in addition to their Pro Rata Share of the Advance, an amount equal to Pro Rata
Share of the Advances of the Lenders not listed on Schedule I-A based on the Pro Rata Share of the Advance for each such Lender relative to the Pro Rata Share of the Advance for all the Lenders listed on Schedule I-A. 

(b) Failures to Fund Commitment Amount. If Borrower has requested an Advance pursuant to Section 2.5(a) of this
Agreement and all of the conditions to the Lender’s obligation to make such Advance as set forth in Section 3 have been satisfied or waived, then (A) if a Lender has nonetheless failed to advance his, her or its Pro Rata Share
of an Advance (hereinafter, with respect to any applicable Lender, referred to as the “Unfunded Capital Commitment Amount”) and such failure is not remedied within five Business Days after written notice thereof is provided by
Borrower to such Lender (the date of such notice, a “Default Notice Date”), in addition to any other remedies Borrower may have for breach of this Agreement, such Lender shall be assessed and shall immediately pay to Borrower a fee
in an amount equal to 5% multiplied by the amount of such Lender’s Unfunded Capital Commitment Amount (such Lender hereinafter referred to as a “Defaulting Lender”), and (B) if such Defaulting Lender fails to fund such
Unfunded Capital Commitment Amount within ten Business Days after the proposed Default Notice Date, in addition to any other remedies Borrower may have for breach of this Agreement, such Defaulting Lender shall be assessed and shall immediately pay
to Borrower an additional fee in an amount equal to 5% multiplied by the amount of such Defaulting Lender’s Unfunded Capital Commitment Amount, such Defaulting Lender shall forfeit the right to participate in any future requests for Advances
made by Borrower, and the other non-Defaulting Lenders who participated in such Advance may fund their respective pro rata shares of the Unfunded Capital Commitment Amount of the Defaulting Lender based on the Pro Rata Share of the Advance for such
non-Defaulting Lenders relative to the Pro Rata Share of the Advance for all the non-Defaulting Lenders. To the extent that any Defaulting Lender 

  
 - 11 -









 
does not pay the fee, the amount of the outstanding Obligations for such Defaulting Lender shall be reduced by the amount of such fee. In no event shall a Lender be deemed a Defaulting Lender if
the Lender is unable to make a Subsequent Advance because the Company limits participation in the Subsequent Advances to the Lenders on Schedule I-A pursuant to Section 2.1(a) above. 

(c) Loans Evidenced by Notes. The obligation of Borrower to repay the unpaid principal amount of and all PIK Interest on the
Loans shall be evidenced by one or more Notes, or in the case of Subsequent Advances addendums to the applicable original Notes issued to the Lenders in connection with the first Subsequent Advance. 

(d) Issuance of Warrants or Common Stock. On the Funding Date for the Initial Advance, (i) for each Lender specified on
Schedule I hereto as purchasing shares of Common Stock, Borrower shall issue and sell to such Lender, and such Lender shall purchase from Borrower, the number of shares of Common Stock set forth opposite such Lender’s name on Schedule
I hereto, at a purchase price of $0.58 per share, and in connection with such purchase the Lender hereby makes to Borrower the representations and warranties set forth in Section 5 of Schedule II, and (ii) for each other Lender,
the Company shall issue such Lender a Warrant covering the number of shares of Common Stock set forth opposite such Lender’s name in Schedule I hereto. 
 (e) Use of Proceeds. The proceeds of the Loans shall be used solely for working capital and other general corporate purposes of Borrower. 

(f) Termination of Commitment to Lend. Notwithstanding anything in the Loan Documents, the Lenders obligation to lend the
undisbursed portion of the Commitment Amount to Borrower hereunder shall terminate on the earlier of (i) at the Required Lenders’ sole election, the occurrence of any Default or Event of Default hereunder, and (ii) the applicable
Commitment Termination Date. 
 2.2 Conversion; Payments. 

(a) Lender’s Option to Convert. The outstanding balances of the Loans made hereunder shall be convertible into capital stock
of Borrower on the terms and conditions set forth in Schedule II to this Agreement. 
 (b) Repayment of Initial
Advance and Subsequent Advances. Subject to the terms and conditions of the Subordination Agreement, all Loans made under this Agreement (including all unpaid principal, accrued interest and PIK Interest thereon) shall be due and payable in full
on the Maturity Date, except to the extent a Loan has been prepaid pursuant to Section 2.3 or converted into capital stock of Borrower pursuant to Schedule II. 

(c) Interest on Loans. Subject to Sections 2.2(a) and (b), the Loans shall bear interest (in addition to any
“original issue discount” as defined in the IRC) at the Loan Rate from the date of the applicable Advance, compounding monthly on each Interest Payment Date; provided, however, Borrower shall not pay such interest in cash but
instead all such accrued and unpaid interest shall be paid in kind as described in the immediately following sentence, on each Interest Payment Date (any such interest paid in kind, the “PIK Interest”). All interest due and payable
hereunder by Borrower shall be capitalized, added to the then-outstanding principal amount of the Loans as additional principal obligations hereunder on and as of such Interest Payment Date and shall automatically constitute a part of the
outstanding principal amount of the Loans for all purposes hereof (including the accrual of interest thereon at the rates applicable to the Loans generally). Any determination of the principal amount outstanding under the Loans after giving effect
to any PIK Interest hereunder or otherwise that is 

  
 - 12 -









 
reasonably made by the Agent or the Lenders in good faith shall be prima facie evidence of the correctness of such determination in the absence of manifest error. All computations of interest
(including interest at the Default Rate, if applicable) shall be based on a year of twelve 30-day months. Notwithstanding any other provision hereof, the amount of interest payable hereunder shall not in any event exceed the maximum amount permitted
by the law applicable to interest charged on commercial loans. 
 (d) Application of Payments. All payments due to the
Lenders hereunder prior to an Event of Default shall be applied as follows: (1) first, to Lenders’ Expenses then due and owing, if applicable, and (2) second, pro rata to the outstanding Loans under Advances made by the Lenders. After
an Event of Default, all payments and application of proceeds shall be made as set forth in Section 9.7. 
 (e)
Default Rate. Borrower shall pay interest at a per annum rate equal to the Default Rate on any amounts required to be paid by Borrower under this Agreement or the other Loan Documents, payable with respect to each Loan, accrued and unpaid
interest, and any fees or other amounts which remain unpaid after such amounts are due. If an Event of Default has occurred and the Obligations have been accelerated (whether automatically or by Lender’s election), Borrower shall pay interest
on the aggregate, outstanding accelerated balance hereunder from the date of the Event of Default until all Events of Default are cured, at a per annum rate equal to the Default Rate. 

2.3 Prepayments. 
 (a) Mandatory Prepayment Upon an Acceleration. If a Loan is accelerated following the occurrence of an Event of Default pursuant to Section 9.1(a) hereof, then Borrower, in addition to
any other amounts which may be due and owing hereunder, shall immediately pay to Lender the amount set forth in Section 2.3(b) below, as if Borrower had opted to prepay on the date of such acceleration. 

(b) Subject to the terms of Section 2.3(a), no prepayments shall be permitted with respect to the Convertible Portion of the
Loans (as defined in Schedule II to this Agreement)Upon ten (10) Business Days’ prior written notice to each Lender, Borrower may, at its option, at any time, prepay all or any portion of the Loans comprising only the
Non-Convertible Portion of the Loans by paying to such Lender an amount equal to (i) any accrued and unpaid interest and PIK Interest on the outstanding principal balance of such Loan(s); (ii) the outstanding principal balance of such
Loan(s) and (iii) all other sums, if any, that shall have become due and payable hereunder. 
 2.4 Other Payment
Terms. 
 (a) Place and Manner. Borrower shall make all payments due to the Lenders in lawful money of the United
States. All payments of principal, PIK Interest, fees and other amounts payable by Borrower hereunder shall be made, in immediately available funds, not later than 10:00 a.m. Pacific time, on the date on which such payment is due. Borrower
shall make such payments to each Lender via wire transfer in immediately available funds or ACH or by certified check at the address set forth for such Lender in Schedule I, as indicated by such Lender in Schedule I (or in a writing
delivered by such Lender to Borrower from and after the Effective Date). 
 (b) Date. Whenever any payment is due
hereunder on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall be included in the computation of interest or fees, as the case may be.

the Warrants and inchoate indemnity obligations) and in order to secure prompt, full and complete performance by Borrower of each of its covenants and duties under each of the Loan Documents
(other than the Warrant). The “Collateral” shall mean and include all right, title, interest, claims and demands of Borrower in and to all personal property of Borrower, including, without limitation, all of the following:

 (a) All goods (and embedded computer programs and supporting information included within the definition of “goods”
under the Code) and equipment now owned or hereafter acquired, including, without limitation, all laboratory equipment, computer equipment, office equipment, machinery, fixtures, vehicles (including motor vehicles and trailers), and any interest in
any of the foregoing, and all attachments, accessories, accessions, replacements, substitutions, additions, and improvements to any of the foregoing, wherever located; 
 (b) All inventory now owned or hereafter acquired, including, without limitation, all merchandise, raw materials, parts, supplies, packing and shipping materials, work in process and finished products
including such inventory as is temporarily out of Borrower’s custody or possession or in transit and including any returns upon any accounts or other proceeds, including insurance proceeds, resulting from the sale or disposition of any of the

 (e) All documents, cash, deposit accounts, letters of credit (whether or not the letter of credit is evidenced by a writing), certificates of deposit, instruments, promissory notes, chattel paper (whether

 - 18 -









 
foregoing, if a judicial authority (including a U.S. Bankruptcy Court) holds that a security interest in the underlying Intellectual Property is necessary to have a security interest in the
Rights to Payment, then the Collateral shall automatically, and effective as of the date hereof, include the Intellectual Property to the extent necessary to permit perfection of Lender’s security interest in the Rights to Payment. 

Notwithstanding the foregoing, the term “Collateral” shall not include (A) equipment identified on Annex I
to the Disclosure Schedule, or (B) or rights of Borrower as a licensee; in each case of (A) and (B) to the extent the granting of a security interest therein (i) would be contrary to applicable law or (ii) is prohibited by
or would constitute a default under any agreement or document governing such property (but only to the extent such prohibition is enforceable under applicable law); provided that upon the termination or lapsing of any such prohibition, such property
shall automatically be part of the Collateral; and provided further that the provisions of this paragraph shall in no case exclude from the definition of “Collateral” any Accounts, proceeds of the disposition of any property, or general
intangibles consisting of rights to payment, all of which shall at all times constitute “Collateral”; and provided further that any Equipment financed by Agent or the Lenders, if any, will at all times constitute “Collateral”.

Code, Borrower shall immediately notify Agent in writing signed by Borrower of the brief details thereof and grant to Lender in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such
writing to be in form and substance satisfactory to Lender. 
 4.3 Duration of Security Interest. Agent’s security
interest in the Collateral shall continue until the payment in full and the satisfaction of all Obligations (other than inchoate indemnity obligations) and termination of Agent and each of the other Lender’s commitment to fund the Loans,
whereupon such security interest shall terminate. Agent shall, at Borrower’s sole cost and expense, execute such further documents and take such further actions as may be reasonably necessary to make effective the release contemplated by this
Section 4.3, including duly authorizing and delivering termination statements for filing in all relevant jurisdictions under the Code. 
 4.4 Location and Possession of Collateral. Other than for Borrower’s personal property located at Flextronics and for Transfers permitted under Section 7.4, the Collateral is and
shall remain in the possession of Borrower at its location listed on the cover page hereof or as set forth in the Disclosure Schedule. Borrower shall remain in full possession, enjoyment and control of the Collateral (except only as may be otherwise
required by Agent for perfection of its security interest therein) and so long as no Event of Default has occurred, shall be entitled to manage, operate and use the same and each part thereof with the rights and franchises appertaining thereto;
provided that the possession, enjoyment, control and use of the Collateral shall at all time be subject to the observance and performance of the terms of this Agreement. 

4.5 Delivery of Additional Documentation Required. Borrower shall from time to time execute and deliver to Agent, at the request
of Lender, all financing statements and other documents Agent may reasonably request, in form satisfactory to Agent, to perfect and continue Agent’s perfected security interests in the Collateral and in order to consummate fully all of the
transactions contemplated under the Loan Documents.

directors, employees, or agents) shall have the right, upon reasonable prior notice, from time to time during Borrower’s usual business hours, to inspect Borrower’s books and records and to make copies thereof and to inspect, test, and
appraise the Collateral in order to verify Borrower’s financial condition or the amount, condition of, or any other matter relating to, the Collateral. 

  
 - 19 -









 4.7 Protection of Intellectual Property. Borrower shall (i) protect, defend and
maintain the validity and enforceability of its Intellectual Property to the extent Borrower deems it appropriate to do so in its reasonable business judgment and promptly advises Lender in writing of material infringements, and (ii) not allow
any Intellectual Property material to Borrower’s business to be abandoned, forfeited or dedicated to the public without Agent’s written consent. 
 4.8 Lien Subordination. Agent agrees that the Liens granted to it hereunder on behalf of and for the ratable benefit of the Lenders under this Agreement shall be subordinate in payment and to the
Liens to secure the Indebtedness permitted under clauses (c), (d) and (e) of the definition of Permitted Indebtedness subject to and in accordance with the terms and provisions of the Subordination Agreement. So long as no Event of Default
has occurred, Agent agrees to execute and deliver such agreements and documents as may be reasonably requested by Borrower from time to time which set forth the payment and lien subordination described in this Section 4.8 and the
Subordination Agreement and are reasonably acceptable to Agent. 
 5. Representations and Warranties. Except as set forth
in the Disclosure Schedule, Borrower represents and warrants as follows: 
 5.1 Organization and Qualification. Borrower
is a corporation duly organized and validly existing under the laws of its state of incorporation and qualified and licensed to do business in, and is in good standing in, any state in which the conduct of its business or its ownership of Property
requires that it be so qualified or in which the Collateral is located, except for such states as to which any failure to so qualify would not have a material adverse effect on Borrower. 

5.2 Authority; Valid Issuance of Common Stock. Borrower has all necessary power and authority to execute, deliver, and perform in
accordance with the terms thereof, the Loan Documents to which it is a party. Borrower has all requisite power and authority to own and operate its Property and to carry on its businesses as now conducted. Borrower has obtained all licenses,

 5.3 Conflict with
Other Instruments, etc. Neither the execution and delivery of any Loan Document to which Borrower is a party nor the consummation of the transactions therein contemplated nor compliance with the terms, conditions and provisions thereof will
conflict with or result in a breach of any of the terms, conditions or provisions of the certificate of incorporation, the by-laws, or any other organizational documents of Borrower or any law or any regulation, order, writ, injunction or decree of
any court or governmental instrumentality or any material agreement or instrument to which Borrower is a party or by which it or any of its Property is bound or to which it or any of its Property is subject, or constitute a default thereunder or

disproportionate manner relative to other participants in the economy or such industry, as applicable, shall be disregarded in determining whether there has been or would be a material adverse effect on Borrower. 

5.10 Full Disclosure. No representation, warranty or other statement made by Borrower in any Loan Document (including the

of the business conducted or to be conducted by Borrower or relating to the use of trade secrets or proprietary information of others, and to Borrower’s knowledge, the continued employment of Borrower’s officers, employees and consultants

applicable laws, including those laws concerning F.I.C.A., F.U.T.A., state disability, and local, state, and federal income taxes, and will, upon request, furnish Lender with proof satisfactory to Agent indicating that Borrower has made such
payments or deposits; provided that Borrower need not make any payment if the amount or validity of such payment is contested in good faith by appropriate proceedings which suspend the collection thereof (provided that
such proceedings do not involve any substantial danger of the sale, forfeiture or loss of any material item of Collateral or Collateral which in the aggregate is material to Borrower and that Borrower has adequately bonded such amounts or reserves
sufficient to discharge such amounts have been provided on the books of Borrower). 
 6.7 Use; Maintenance. Borrower

property, without the prior written consent of Lender. Borrower shall not permit any such material item of Collateral to be operated or maintained in violation of any applicable law, statute, rule or regulation. With respect to items of leased

keep, maintain, repair, replace and operate such leased equipment in accordance with the terms of the applicable lease. 
 6.8 Insurance. Borrower shall keep its business and the Collateral insured for risks and in amounts, as the Agent may reasonably request. Insurance policies shall be in a form, with companies, and
in amounts that are satisfactory to Agent. All property policies shall have a lender’s loss payable endorsement showing Agent on behalf of and for the ratable benefit of the Lenders as an additional loss payee and all liability policies shall
show Agent as an additional insured. Borrower shall provide Agent at least twenty (20) days notice before cancellation of its insurance policies. At Agent’s request, Borrower shall deliver certified copies of policies and evidence of all
premium payments. Proceeds payable under any property policy shall, at Agent’s option, be payable to Agent on behalf of and for the ratable benefit of the Lenders on account of the Obligations. Notwithstanding the foregoing, so long as no Event
of Default has occurred and is continuing, Borrower shall have the option of applying the proceeds of any property policy, toward the replacement or repair of destroyed or damaged property; provided that (i) any such replaced or repaired
property (a) shall be of equal or like value as the replaced or repaired Collateral and (b) shall be deemed Collateral in which Lender has been granted a first priority security interest and (ii) after the occurrence and during the
continuation of an Event of Default all proceeds payable under such property policy shall, at the option of Lender, be payable to Lender, on account of the Obligations. If Borrower fails to obtain insurance as required under Section 6.8
or to pay any amount or furnish any required proof of payment to third persons and Lender, Lender may make all or part of such payment or obtain such insurance policies required in Section 6.8, and take any action under the policies
Lender deems prudent. On or prior to the first Funding Date and prior to each policy renewal, Borrower shall furnish to Lender certificates of insurance or other evidence satisfactory to Lender that insurance complying with all of the above
requirements is in effect. 
 6.9 Security Interest. Assuming the proper filing of one or more financing statement(s)
identifying the Collateral with the proper state and/or local authorities, the security interests in the Collateral granted to Lender pursuant to this Agreement (i) constitute and will continue to constitute first priority security interests

such Permitted Liens). 
 6.10 Further Assurances. At any time and from time to time Borrower shall execute and deliver
such further instruments and take such further action as may reasonably be requested by Agent to make effective the purposes of this Agreement, including without limitation, the continued perfection and priority of Agent’s security interest in
the Collateral. 
 6.11 Subsidiaries. Borrower, upon Agent’s reasonable request, shall cause any Subsidiary of
Borrower to provide Lender with a guaranty of the Obligations and a security interest in such Subsidiary’s assets to secure such guaranty. Borrower shall not create or otherwise have any Subsidiaries after the date hereof, except for
Subsidiaries for which Borrower obtained Agent’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed) and otherwise subject to the first sentence of this Section 6.11. 

6.12 Notices Regarding Warranty Claim Rate. If as of the first day of any calendar month prior to the Commitment Termination Date,

more of the following, all of which are authorized by Borrower:

contest, or compromise any Lien which in Agent’s determination appears or is claimed to be prior or superior to its security interest and to pay all expenses incurred in connection therewith. With respect to any of Borrower’s owned
premises, Borrower hereby grants Agent a license to enter into possession of such premises and to occupy the same, without charge, for up to one hundred twenty (120) days in order to exercise any of Agent’s rights or remedies provided

use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any Property of a similar nature, now or at any time hereafter owned or acquired by Borrower or in which Borrower now or at any time hereafter has any
rights; provided that such license shall only be exercisable in connection with the disposition of Collateral upon Agent’s exercise of its remedies hereunder; 

(d) Sale of Collateral. Sell the Collateral at either a public or private sale, or both, by way of one or more contracts or
transactions, for cash or on terms, in such manner and at such places (including Borrower’s premises) as Agent determines are commercially reasonable; and

permitted by law, Borrower covenants that it will not at any time insist upon or plead, or in any manner whatsoever claim or take any benefit or advantage of, any stay or extension law now or at any time hereafter in force, nor claim, take nor
insist upon any benefit or advantage of or from any law now or hereafter in force providing for the valuation or appraisement of the Collateral or any part thereof prior to any sale or sales thereof to be made pursuant to any provision herein
contained, or to the decree, judgment or order of any court of competent jurisdiction; nor, after such sale or sales, claim or exercise any right under any statute now or hereafter made or enacted by any state or otherwise to redeem the property so
sold or any part thereof, and, to the full extent legally permitted, except as to rights expressly provided herein, hereby expressly waives for itself and on behalf of each and every Person, except decree or judgment creditors of Borrower, acquiring
any interest in or title to the Collateral or any part thereof subsequent to the date of this Agreement, all benefit and advantage of any such law or laws, and covenants that it will not invoke or utilize any such law or laws or otherwise hinder,
delay or impede the execution of any power herein granted and delegated to Agent, but will suffer and permit the execution of every such power as though no such power, law or laws had been made or enacted. Any sale, whether under any power of sale
hereby given or by virtue of judicial proceedings, shall operate to divest all right, title, interest, claim and demand whatsoever, either at law or in equity, of Borrower in and to the Property sold, and shall be a perpetual bar, both at law and in
equity, against Borrower, its successors and assigns, and against any and all Persons claiming the Property sold or any part thereof under, by or through Borrower, its successors or assigns. 

9.4 Power of Attorney in Respect of the Collateral. Borrower does hereby irrevocably appoint Agent (which appointment is coupled
with an interest), the true and lawful attorney in fact of Borrower with full power of substitution, for it and in its name to file any notices of security interests, financing statements and continuations and amendments thereof pursuant to the Code
or federal law, as may be necessary to perfect, or to continue the perfection of Agent’s security interests in the Collateral. Borrower does hereby irrevocably appoint Agent (which appointment is coupled with an interest) on the occurrence of
an Event of Default, the true and lawful attorney in fact of Borrower with full power of substitution, for it and in its name: (a) to ask, demand, collect, receive, receipt for, sue for, compound and give acquittance for any and all rents,
issues, profits, avails, distributions, income, payment draws and other sums in which a security interest is granted under Section 4 with full power to settle, adjust or compromise any claim thereunder as fully as if Agent were Borrower
itself; (b) to receive payment of and to endorse the name of Borrower to any items of Collateral (including checks, drafts and other orders for the payment of money) that come into Agent’s possession or under Agent’s control;
(c) to make all demands, consents and waivers, or take any other action with respect to, the Collateral; (d) in Agent’s discretion to file any claim or take any other action or proceedings, either in its own name or in the name of
Borrower or otherwise, which Agent may reasonably deem necessary or appropriate to protect and preserve the right, title and interest of Agent in and to the Collateral; (e) endorse Borrower’s name on any checks or other forms of payment or
security; (f) sign Borrower’s name on any invoice or bill of lading for any account or drafts against account debtors; (g) make, settle, and adjust all claims under Borrower’s insurance policies; (h) settle and adjust
disputes and claims about the accounts directly with account debtors, for amounts and on terms Agent determines reasonable; (i) transfer the Collateral into the name of Agent or a third party as the Code permits; and (j) to otherwise act
with respect thereto as though Agent were the outright owner of the Collateral. 
 9.5 Lenders’ Expenses. If
Borrower fails to pay any amounts or furnish any required proof of payment due to third persons or entities, as required under the terms of this Agreement, then Agent, with the written consent or at the written direction of the Required Lenders, may
do any or all of the following: (a) make payment of the same or any part thereof; or (b) obtain and maintain insurance policies of the type discussed in Section 6.8 of this Agreement, and take any action with respect to such
policies as Agent deems prudent. Any amounts paid or deposited by Agent shall constitute Lenders’ 

  
 - 30 -









 
Expenses (and payable and reimbursable to Agent), shall be immediately due and payable, shall bear interest at the Default Rate and shall be secured by the Collateral. Any payments made by Agent
or any Lender shall not constitute an agreement by Agent or such Lender to make similar payments in the future or a waiver by Agent or such Lender of any Event of Default under this Agreement. Borrower shall pay all reasonable fees and expenses,
including without limitation, Lenders’ Expenses, incurred by Agent or any Lender in the enforcement or attempt to enforce any of the Obligations hereunder not performed when due. 

9.6 Remedies Cumulative. Each of Agent’s and each Lender’s rights and remedies under this Agreement, the Loan Documents,
and all other agreements shall be cumulative. Agent and each Lender shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Agent or any Lender of one right or remedy shall
be deemed an election, and no waiver by Agent or such Lender of any Event of Default on Borrower’s part shall be deemed a continuing waiver. No delay by Agent or any Lender shall constitute a waiver, election, or acquiescence by it. 

9.7 Application of Collateral Proceeds. The proceeds and/or avails of the Collateral, or any part thereof, and the proceeds and
the avails of any remedy hereunder (as well as any other amounts of any kind held by Agent or any Lender, at the time of or received by Agent or any Lender after the occurrence of an Event of Default hereunder) shall be paid to and applied as
follows: 
 (a) First, to the payment of out-of-pocket costs and expenses, including all amounts expended to preserve
the value of the Collateral, of foreclosure or suit, if any, and of such sale and the exercise of any other rights or remedies, and of all proper fees, expenses, liability and advances, including reasonable legal expenses and attorneys’ fees,
incurred or made hereunder by Agent and the Lenders, including, without limitation, Lenders’ Expenses; 
 (b)
Second, to the payment to each Lender, on a ratable basis, of the amount then owing or unpaid on the Loans for any accrued and unpaid interest, the amounts which would have otherwise come due under Section 2.3(b)(ii), if the Loans
had been voluntarily prepaid, the principal balance of the Loans, and all other Obligations with respect to the Loans held by such Lender (provided, however, if such proceeds shall be insufficient to pay in full the whole amount so
due, owing or unpaid upon the Loans, then to the unpaid interest thereon, then to the amounts which would have otherwise come due under Section 2.3(b)(ii), if the Loans had been voluntarily prepaid, then to the principal balance of the
Loans, and then to the payment of other amounts then payable to Lender under any of the Loan Documents); and 
 (c)
Third, to the payment of the surplus, if any, to Borrower, its successors and assigns, or to the Person lawfully entitled to receive the same. 
 9.8 Reinstatement of Rights. If Agent and any Lender shall have proceeded to enforce any right under this Agreement or any other Loan Document by foreclosure, sale, entry or otherwise, and such
proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely, then and in every such case (unless otherwise ordered by a court of competent jurisdiction), Agent and any such Lender shall be restored to
its former position and rights hereunder with respect to the Property subject to the security interest created under this Agreement. 
 10. Waivers; Indemnification. 
 10.1 Demand; Protest. Borrower waives
demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, 

  
 - 31 -









 
release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees at any time held by the Lenders on which Borrower may in any way be
liable. 
 10.2 Lender’s Liability for Collateral. So long as Agent or any Lender complies with its obligations, if
any, under the Code, neither Agent nor any Lender shall in any way or manner be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage thereto occurring or arising in any manner or fashion from any cause
other than Lender’s gross negligence or willful misconduct; (c) any diminution in the value thereof; or (d) any act or default of any carrier, warehouseman, bailee, forwarding agency, or other Person whomsoever. All risk of loss,
damage or destruction of the Collateral shall be borne by Borrower. 
 10.3 Indemnification and Waiver. Whether or not
the transactions contemplated hereby shall be consummated: 
 (a) General Indemnity. Borrower agrees upon demand to pay
or reimburse each Lender for all liabilities, obligations and out-of-pocket expenses, including all Lenders’ Expenses and reasonable fees and expenses of counsel for Lender from time to time arising in connection with the enforcement or
collection of sums due under the Loan Documents, and in connection with any amendment or modification of the Loan Documents or any “work-out” in connection with the Loan Documents. Borrower shall indemnify, reimburse and hold each Lender,
and each of its respective successors, assigns, agents, attorneys, officers, directors, equity holders, servants, agents and employees (each an “Indemnified Person”) harmless from and against all liabilities, losses, damages,
actions, suits, demands, claims of any kind and nature (including claims relating to environmental discharge, cleanup or compliance), all costs and expenses whatsoever to the extent they may be incurred or suffered by such Indemnified Person in
connection therewith (including reasonable attorneys’ fees and expenses), fines, penalties (and other charges of any applicable Governmental Authority), licensing fees relating to any item of Collateral, damage to or loss of use of property
(including consequential or special damages to third parties or damages to Borrower’s property), or bodily injury to or death of any person (including any agent or employee of Borrower) (each, a “Claim”), directly or indirectly
relating to or arising out of the use of the proceeds of the Loans or otherwise, the falsity of any representation or warranty of Borrower or Borrower’s failure to comply with the terms of this Agreement or any other Loan Document. The
foregoing indemnity shall cover, without limitation, (i) any Claim in connection with a design or other defect (latent or patent) in any item of equipment or product included in the Collateral, (ii) any Claim for infringement of any
patent, copyright, trademark or other intellectual property right, (iii) any Claim resulting from the presence on or under or the escape, seepage, leakage, spillage, discharge, emission or release of any Hazardous Materials on the premises
owned, occupied or leased by Borrower, including any Claims asserted or arising under any Environmental Law, (iv) any Claim for negligence or strict or absolute liability in tort, or (v) any Claim asserted as to or arising under any
Account Control Agreement or any Landlord Agreement; provided, however, Borrower shall not indemnify any Lender for any liability incurred by such Lender as a direct and sole result of such Lender’s gross negligence or willful
misconduct. Such indemnities shall continue in full force and effect, notwithstanding the expiration or termination of this Agreement. Upon any Lender’s written demand, Borrower shall assume and diligently conduct, at its sole cost and expense,
the entire defense of such Lender, each of its members, partners, and each of their respective, agents, employees, directors, officers, equity holders, successors and assigns against any indemnified Claim described in this
Section 10.3(a). Borrower shall not settle or compromise any Claim against or involving any Lender without first obtaining such Lender’s written consent thereto, which consent shall not be unreasonably withheld. 

(b) Waiver. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT OR ANYWHERE ELSE, BORROWER AGREES THAT IT


  
 - 32 -









 
SHALL NOT SEEK FROM LENDER UNDER ANY THEORY OF LIABILITY (INCLUDING ANY THEORY IN TORTS), ANY SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES. 

(c) Survival; Defense. The obligations in this Section 10.3 shall survive payment of all other Obligations pursuant
to Section 12.8. At the election of any Indemnified Person, Borrower shall defend such Indemnified Person using legal counsel satisfactory to such Indemnified Person in such Person’s reasonable discretion, at the sole cost and
expense of Borrower. All amounts owing under this Section 10.3 shall be paid within thirty (30) days after written demand. 
 11. Notices. Unless otherwise provided in this Agreement, all notices or demands by any party relating to this Agreement or any other agreement entered into in connection herewith shall be in

shall bind and inure to the benefit of the respective successors and permitted assigns of each of the parties; provided, however, neither this Agreement nor any rights hereunder may be assigned by Borrower without the prior written
consent of the Required Lenders, which consent may be granted or withheld in the sole discretion of the Required Lenders. Each Lender shall have the right without the consent of or notice to Borrower to sell, transfer, assign, negotiate, or grant
participations (an “Assignment”) in all or any part of, or any interest in such Lender’s rights and benefits hereunder provided that such Lender shall cause to be executed and delivered by any such assignee an

must sell, transfer and assign not less than the lesser of $1,000,000 in Advances held by or in favor of such Lender or 100% of all Advances held by or in favor of such Lender. Each Lender may disclose the Loan Documents and any other financial or

using the same measures that it uses to protect its own confidential information. 
 12.3 Time of Essence. Time is of the
essence for the performance of all obligations set forth in this Agreement. 
 12.4 Severability of Provisions. Each
provision of this Agreement shall be severable from every other provision of this Agreement for the purpose of determining the legal enforceability of any specific provision. 
 12.5 Entire Agreement; Construction; Amendments and Waivers. 
 (a)
Entire Agreement. This Agreement and each of the other Loan Documents dated as of the date hereof, taken together, constitute and contain the entire agreement among Borrower, Agent and the Lenders and supersede any and all prior agreements,
negotiations, correspondence, understandings and communications between the parties, whether written or oral, respecting the subject matter hereof. Borrower acknowledges that it is not relying on any representation or agreement made by any Lender or
any employee, attorney or agent thereof, other than the specific agreements set forth in this Agreement and the Loan Documents. 
 (b) Construction. This Agreement is the result of negotiations between and has been reviewed by each of Borrower, Agent and each Lender as of the date hereof and their respective counsel;
accordingly, this Agreement shall be deemed to be the product of the parties hereto, and no ambiguity shall be construed in favor of or against Borrower, Agent or any Lender. Each of Borrower, Agent and each Lender agree that they intend the literal
words of this Agreement and the other Loan Documents and that no parol evidence shall be necessary or appropriate to establish Borrower’s, Agent’s or such Lender’s actual intentions. 

(c) Amendments and Waivers. Any and all discharges or waivers of, or consents to any departures from any provision of this
Agreement or of any of the other Loan Documents shall not be effective without the written consent of the Required Lenders. Any and all amendments and modifications of this Agreement or of any of the other Loan Documents shall not be effective
without the written consent of Borrower and the Required Lenders. Any waiver or consent with respect to any provision of the Loan Documents shall be effective only in the specific instance and for the specific purpose for which it was given. No
notice to or demand on Borrower in any case shall entitle Borrower 

  
 - 34 -









 
to any other or further notice or demand in similar or other circumstances. Any amendment, modification, waiver or consent affected in accordance with this Section 12.5(c) shall be
binding upon the Lenders and on Borrower; provided, however, that (1) any amendment, modification, waiver or consent that treats or affects a Lender in a materially unequal fashion as compared to all other Lenders shall require the consent of
the Lender receiving such unequal treatment; and (2) any amendment, modification, waiver or consent that (i) increases the Commitment Amount or the Pro Rata Share of any Lender, (ii) decreases the principal amount of the Note held by
any Lender (other than pursuant to Section 2.1(b)) or the number of shares issuable to any Lender upon the exercise of any Warrant held by such Lender, or (iii) increases the Conversion Price applicable to the conversion of any Note held
by a Lender (other than any adjustment pursuant to Section 4 of Schedule II to this Agreement), shall require the consent of the affected Lender. 
 12.6 Reliance by Lender. All covenants, agreements, representations and warranties made herein by Borrower shall be deemed to be material to and to have been relied upon by each Lender,
notwithstanding any investigation by such Lender. 
 12.7 No Set-Offs by Borrower. All sums payable by Borrower pursuant
to this Agreement or any of the other Loan Documents shall be payable without notice or demand and shall be payable in United States Dollars without set-off or reduction of any manner whatsoever. 

12.8 Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts
(including signatures delivered by facsimile or other electronic means), each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement.

 12.9 Survival. All covenants, representations and warranties made in this Agreement shall continue in full force and
effect so long as any Obligations or commitment to fund remain outstanding. The obligations of Borrower to indemnify the Lenders with respect to the expenses, damages, losses, costs and liabilities described in Section 10.3 shall survive
until all applicable statute of limitations periods with respect to actions that may be brought against the Lenders have run. 

13. Relationship of Parties. Borrower and each Lender acknowledge, understand and agree that the relationship between Borrower, on
the one hand, and such Lender, on the other, is, and at all time shall remain solely that of a borrower and lender. Such Lender shall not under any circumstances be construed to be a partner or a joint venturer of Borrower or any of its Affiliates;
nor shall such Lender under any circumstances be deemed to be in a relationship of confidence or trust or a fiduciary relationship with Borrower or any of its Affiliates, or to owe any fiduciary duty to Borrower or any of its Affiliates. Such Lender
does not undertake or assume any responsibility or duty to Borrower or any of its Affiliates to select, review, inspect, supervise, pass judgment upon or otherwise inform Borrower or any of its Affiliates of any matter in connection with its or
their Property, any Collateral held by such Lender or the operations of Borrower or any of its Affiliates. Borrower and each of its Affiliates shall rely entirely on their own judgment with respect to such matters, and any review, inspection,
supervision, exercise of judgment or supply of information undertaken or assumed by such Lender in connection with such matters is solely for the protection of such Lender and neither Borrower nor any Affiliate is entitled to rely thereon.

 14. CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF CALIFORNIA, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS. EACH OF BORROWER AND LENDER HEREBY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS LOCATED IN THE


  
 - 35 -









 
NORTHERN DISTRICT OF CALIFORNIA. BORROWER AND LENDER HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR
ANY OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. 
 15. Waiver of Conflicts. Each party to this Agreement acknowledges that Cooley LLP (“Cooley”), outside general counsel to the Borrower, has in the past performed and is or may now or in
the future represent one or more Lenders or their affiliates in matters unrelated to the transactions contemplated by this Agreement (the “Subordinated Loan Facility”), including representation of such Purchasers or their affiliates
in matters of a similar nature to the Subordinated Loan Facility. The applicable rules of professional conduct require that Cooley inform the parties hereunder of this representation and obtain their consent. Cooley has served as outside general
counsel to the Borrower and has negotiated the terms of the Loans solely on behalf of the Borrower. The Borrower and each Lender hereby (a) acknowledge that they have had an opportunity to ask for and have obtained information relevant to such
representation, including disclosure of the reasonably foreseeable adverse consequences of such representation; (b) acknowledge that with respect to the Subordinated Loan Facility, Cooley has represented solely the Borrower, and not any Lender
or any stockholder, director or employee of the Borrower or any Lender; and (c) gives its informed consent to Cooley’s representation of the Borrower in the Subordinated Loan Facility.

 Terms for Conversion of Outstanding Balance on Advances 

1. DEFINITION. The following definitions shall apply for all purposes of this Schedule II to the Agreement: 

“Actual Conversion Amount” means the amount of the outstanding balance of a Loan (including for clarity the
aggregate outstanding principal and all accrued interest and PIK Interest in respect of such Loan) converted into Conversion Stock pursuant to Section 2 of this Schedule II. 

“Actual Conversion Date” means the date on which any of the outstanding balance of a Loan is converted pursuant to
Section 2 of this Schedule II. 
 “Conversion Price” means the lower of (a) $0.98 or
(b) the lowest per share selling price of any shares of capital stock sold by Borrower following the Effective Date, other than shares of capital stock sold in a transaction that would be exempt from the anti-dilution rights of the holders of
Borrower’s preferred stock pursuant to clauses (i) through (viii) of Article V, Section 5.8 of Borrower’s certificate of incorporation, as in effect on the Effective Date. The Conversion Price is subject to adjustment as
provided herein. 
 “Conversion Stock” means Borrower’s Common Stock. The number and character of shares
of Conversion Stock are subject to adjustment as provided in Section 4 of this Schedule II and the term “Conversion Stock” shall include the stock and other securities and property that are, on the Actual Conversion
Date, receivable or issuable upon such conversion of a Note in accordance with Section 4 of this Schedule II. 
 “Dividend Event” has the meaning set forth in Section 4.2 of this Schedule II. 
 “Lost Note Documentation” means documentation reasonably satisfactory to Borrower with regard to a lost or stolen Note, including, if required by Borrower, an affidavit of lost note and
an indemnification agreement by the respective Lender in favor of Borrower with respect to such lost or stolen Note. 

“Maximum Conversion Amount” means: 
 (a) with respect to any Loan comprising part of the Initial Advance, the amount of the entire outstanding balance of such Loan (including for clarity the aggregate outstanding principal and all accrued
interest and PIK Interest in respect of such Loan), and 
 (b) with respect to any Loan comprising part of a Subsequent Advance,
an amount equal to fifty percent (50%) of the initial outstanding principal amount of such Loan plus all accrued interest and PIK Interest in respect of such portion of the principal amount (the outstanding balance of the Initial Advance and
convertible portion of the Subsequent Advances being sometimes referred to herein as the “Convertible Portion of the Loans” and the non-convertible portion of the Subsequent Advances being referred to herein as the
“Non-Convertible Portion of the Loans”)); provided that if the Maturity Date occurs by reason of an IPO and either (i) Borrower is prohibited from paying, (ii) the Lenders are otherwise prohibited from receiving or
accepting payment for, or (iii) Borrower otherwise fails to pay when due the outstanding balance on any Subsequent Advance due in connection with the consummation of the IPO, including without limitation by reason of a default or event of
default under the Senior Secured Loan and Security Agreement and/or the Senior Subordinated Secured Loan and Security Agreement or the application of the terms of the 

  
 1 








 
Subordination Agreement, then the “Maximum Conversion Amount” with respect to the foregoing clause (b) shall be deemed to be one hundred percent (100%) of the amount of the
outstanding balance of such Loans. 
 “Reorganization Event” has the meaning set forth in
Section 4.3 of this Schedule II. 
 “Stock Event” has the meaning set forth in
Section 4.4 of this Schedule II. 
 2. CONVERSION. 

2.1 Optional Conversion Prior to Maturity Date. Upon the election of a Lender with respect to any Loan made by it, which election
shall be exercised by written notice from such Lender given to Borrower prior to Borrower’s repayment in full of the outstanding balance of such Loan (which election, in the event the Maturity Date is anticipated to occur due to the
consummation of a Change in Control or IPO, may at Lender’s option be made contingent upon the completion of such Change in Control or IPO), the entire Maximum Conversion Amount of such Loan, or any portion thereof as specified in such election
of the Lender, shall be cancelled and converted into that number of shares of Conversion Stock obtained by dividing (i) the entire Maximum Conversion Amount of such Loan or portion thereof specified by the Lender, by (ii) the Conversion
Price. 
 2.2 Timing of Conversion; Tender of Note or Addendum Thereto for Conversion. In connection with a conversion
pursuant to Section 2.1, a Lender shall deliver the original Note or the applicable addendum thereto corresponding to such Loan (or Lost Note Documentation, if applicable) to Borrower. If a Lender elects to convert only a portion of the
Loan represented by a Note or addendum, as the case may be, then promptly after (and in any event within 7 days after) receipt of the original Note or such addendum (or Lost Note Documentation, if applicable) Borrower shall re-issue such Lender a
new Note or addendum reflecting the portion of such Loan that was not converted and remains outstanding. If a Lender delivers written notice of an election to convert a Loan (or portion thereof) within the time period specified in
Section 2.1, the conversion of such Loan (or portion thereof) into Conversion Stock shall be deemed to occur upon the earlier of (i) the date of such Lender’s written notice (unless the Lender has elected to make conversion of
the Loan contingent on the consummation of a Change in Control or IPO) and (ii) immediately prior to the Maturity Date, without regard to whether Lender has then delivered to Borrower the Note(s) corresponding to the Loan so converted (or the
Lost Note Documentation where applicable) or executed any other documents. 
 2.3 Termination of Rights. Except for the
right to obtain certificates representing the Conversion Stock under Section 3 below, all rights with respect to a Loan (or portion thereof) converted pursuant this Section 2 shall terminate upon the effective conversion of
such Loan (or portion thereof) as provided in Section 2.1 above. 
 3. CERTIFICATES; NO FRACTIONAL SHARES.
Subject to Section 2.2 above, as soon as practicable after conversion of a Loan pursuant to Section 2.1 above, Borrower at its expense will register such shares of Conversion Stock in Borrower’s stockholder register in
the name of the applicable Lender and will cause to be issued in the name of such Lender and to be delivered to such Lender, a certificate or certificates for the number of shares of Conversion Stock to which such Lender shall be entitled upon such
conversion (bearing such legends as may be required by applicable state and federal securities laws in the opinion of legal counsel of Borrower, by Borrower’s Certificate of Incorporation and Bylaws and by any agreement between Borrower and
such Lender), together with any other securities and property to which such Lender is entitled upon such conversion under the terms of such Loan; provided that in the event that the conversion is effected upon an IPO, Borrower may issue
uncertificated shares. No fractional shares shall be 

  
 2 








 
issued upon conversion of a Loan. If upon any conversion of a Loan, a fraction of a share would otherwise be issued, then in lieu of such fractional share, Borrower shall pay to the applicable
Lender an amount in cash equal to such fraction of a share multiplied by the applicable Conversion Price. 
 4. ADJUSTMENT
PROVISIONS. So long as any of the aggregate balance of the Loans remains outstanding, the number and character of shares of Conversion Stock issuable upon conversion of a Loan upon an Actual Conversion Date and, to the extent set forth in this
Section 4, the Conversion Price therefor, are each subject to adjustment upon each occurrence of an adjustment event described in Sections 4.1 through 4.4 below occurring between the Effective Date and such Actual
Conversion Date: 
 4.1 Adjustment for Stock Splits and Stock Dividends. The Conversion Price and the number of shares of
Conversion Stock shall each be proportionally adjusted to reflect any stock dividend, stock split, reverse stock split or other similar event affecting the number of outstanding shares of Conversion Stock without the payment of consideration to
Borrower therefor at any time before an Actual Conversion Date. 
 4.2 Adjustment for Other Dividends
and Distributions. If Borrower shall make or issue, or shall fix a record date for the determination of eligible holders of its capital stock entitled to receive, a dividend or other distribution payable with respect to the Conversion Stock
that is payable in securities of Borrower (other than issuances with respect to which adjustment is made under Section 4.1 or 4.3 of this Schedule II), or in assets (other than cash dividends) (each, a “Dividend
Event”), and such dividend or other distribution is actually made, then, and in each such case, a Lender, upon conversion of an Actual Conversion Amount at any time after such Dividend Event, shall receive, in addition to the Conversion Stock
issuable upon such conversion of its Note, the securities or other assets that would have been issuable to such Lender had such Lender, immediately prior to such Dividend Event, converted such Actual Conversion Amount into Conversion Stock.

 4.3 Adjustment for Consolidation or Merger. If Borrower shall consolidate with or merge into one or more other
corporations or other entities (and for clarity the Loans shall not have already been repaid and/or are not being repaid in connection with the consummation of such consolidation or merger), and pursuant to such consolidation or merger stock, other
securities or other property is issued or paid to holders of Conversion Stock (each, a “Reorganization Event”), then, and in each such case, a Lender, upon conversion of an Actual Conversion Amount after the consummation of such
Reorganization Event, shall be entitled to receive (in lieu of the stock or other securities and property that such Lender would have been entitled to receive under the terms of its Note upon such conversion but for such Reorganization Event), the
stock or other securities or property that such Lender would have been entitled to receive upon the consummation of such Reorganization Event if, immediately prior to such Reorganization Event, such Lender had converted such Actual Conversion Amount
into Conversion Stock, all subject to further adjustment as provided herein, and the successor corporation or other successor entity in such Reorganization Event shall duly execute and deliver to such Lender a supplement to such Note acknowledging
such corporation’s or other entity’s obligations under such Note; and in each such case, the terms of such Note shall be applicable to the shares of stock or other securities or property receivable upon the conversion of such Note after
the consummation of such Reorganization Event. 
 4.4 Conversion of Stock. In each case not otherwise covered in
Section 4.3 above where (i) all the outstanding Conversion Stock is converted, pursuant to the terms of Borrower’s Certificate of Incorporation, into other securities or property, or (ii) the Conversion Stock otherwise
ceases to exist or to be authorized under Borrower’s Certificate of Incorporation (each a “Stock Event”), then Lender, upon conversion of this Note at any time after such Stock Event, shall receive, in lieu of the number of
shares of 

  
 3 








 
Conversion Stock that would have been issuable upon conversion of this Note immediately prior to such Stock Event, the stock and other securities and property that Lender would have been entitled
to receive upon the Stock Event, if immediately prior to such Stock Event, Lender had converted the Actual Conversion Amount into Conversion Stock. 
 4.5 Notice of Adjustments. Borrower shall promptly give written notice of each adjustment of the Conversion Price or the number or type of shares of Conversion Stock or other securities or property
issuable upon conversion of a Note that is required under this Section 4. The notice shall describe the adjustment or readjustment and show in reasonable detail the facts on which the adjustment or readjustment is based. 

4.6 Reservation of Stock. If the number of shares of Conversion Stock or other securities authorized and reserved for issuance
upon conversion of the Notes shall not be sufficient to effect the conversion of the aggregate Maximum Conversion Amounts of the Notes, then Borrower shall take such corporate action as may, in the opinion of its counsel, be necessary to increase
its authorized but unissued shares of Conversion Stock or other securities issuable upon conversion of the Notes as shall be sufficient for such purpose. 
 5. REPRESENTATIONS AND WARRANTIES AND COVENANTS OF THE LENDERS 
 5.1
Purchase for Own Account. Each Lender represents that it is acquiring the Notes, the Warrants, the Conversion Stock and the Common Stock, as the case may be (collectively, the “Securities”), solely for its own account and
beneficial interest for investment and not for sale or with a view to distribution of the Securities or any part thereof, has no present intention of selling (in connection with a distribution or otherwise), granting any participation in, or
otherwise distributing the same, and does not presently have reason to anticipate a change in such intention. Notwithstanding the foregoing, KPCB Holdings, Inc. is acquiring the Securities as a nominee. 

5.2 Information and Sophistication. Without lessening or obviating the representations and warranties of the Borrower set forth in
Section 5 of the Loan Agreement, each Lender hereby: (i) acknowledges that it has received all the information it has requested from the Borrower and it considers necessary or appropriate for deciding whether to acquire the Securities,
(ii) represents that it has had an opportunity to ask questions and receive answers from the Borrower regarding the terms and conditions of the offering of the Securities and to obtain any additional information necessary to verify the accuracy
of the information given the Lender and (iii) further represents that it has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risk of this investment. 

5.3 Ability to Bear Economic Risk. Each Lender acknowledges that investment in the Securities involves a high degree of risk, and
represents that it is able, without materially impairing its financial condition, to hold the Securities for an indefinite period of time and to suffer a complete loss of its investment. 

5.4 Further Limitations on Disposition. Without in any way limiting the representations set forth above, each Lender further
agrees not to make any disposition of all or any portion of the Securities unless and until: 
 (a) There is then in effect a
Registration Statement under the Act covering such proposed disposition and such disposition is made in accordance with such Registration Statement; or 

  
 4 








 (b) The Lender shall have notified the Borrower of the proposed disposition and shall have
furnished the Borrower with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Borrower, such Lender shall have furnished the Borrower with an opinion of counsel, reasonably
satisfactory to the Borrower, that such disposition will not require registration under the Act or any applicable state securities laws, provided that no such opinion shall be required for dispositions in compliance with Rule 144, except in unusual
circumstances. 
 Notwithstanding the provisions of paragraphs (a) and (b) above, no such registration statement or
opinion of counsel shall be required: (i) for any transfer of any Conversion Stock, Common Stock and shares of Common Stock issued or issuable upon exercise of any Warrant in compliance with SEC Rule 144 or Rule 144A, or (ii) for any
transfer of any Conversion Stock, Common Stocker shares of Common Stock issued or issuable upon exercise of any Warrant that is a partnership, limited liability company or corporation to (A) a partner (or retired partner) or member (or retired
member) of such Lender in accordance with partnership or limited liability company interests or stock or other equity interests of such entity or (B) an Affiliate of such Lender that is a limited liability company or corporation, or
(iii) for any transfers by gift, will or intestate succession to any spouse or lineal descendants or ancestors, if all transferees agree in writing to be subject to the terms hereof to the same extent as if they were Lenders hereunder.

 5.5 Accredited Investor Status. Each Lender is an “accredited investor” as such term is defined in
Rule 501 under the Act. 
 5.7 Lock-Up Agreement. Each Lender acknowledges that the Conversion Stock, Common Stock and
any shares of Common Stock issued upon exercise of the Warrant held by such Lender shall be bound by the lock-up provisions set forth in Section 1.13 of the Amended and Restated Investors’ Rights Agreement dated as of March 15, 2010
by and between the Borrower and certain investors in the Borrower, to which Lender, or an Affiliate of the Lender, is a party.

balance of any Loans associated with this Note or any addendum or supplement to this Note, as described in the Loan Agreement. 

If not sooner paid, all outstanding amounts hereunder and under the Loan Agreement shall become due and payable on the Maturity Date (as

money of the United States of America to Lender as set forth in the Loan Agreement. The principal amount of this Note and the interest rate applicable thereto, and all payments made with respect thereto, shall be recorded by Lender and, prior to any
transfer hereof, endorsed on the grid attached hereto which is part of this Note. 
 This Note is referred to in, and is
entitled to the benefits of, the Subordinated Convertible Loan Facility and Security Agreement by and among Borrower, KPCB Holdings, Inc., as nominee, as a Lender and as Agent on behalf of and for the ratable benefit of the Lenders, and the other
Lenders named therein (as amended, amended and restated, joined, supplemented or otherwise modified from time to time, the “Loan Agreement”). The Loan Agreement, among other things, (a) provides for the making of secured Loans
to Borrower, and (b) contains provisions for acceleration of the maturity hereof upon the happening of certain stated events. All capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Loan Agreement.

 SCHEDULE II 

Terms for Conversion of Outstanding Balance on Advances 
 1. DEFINITION. The following definitions shall apply for all purposes of this Schedule II to the Agreement: 
 “Actual Conversion Amount” means the amount of the outstanding balance of a Loan (including for clarity the aggregate outstanding principal and all accrued interest and PIK Interest in
respect of such Loan) converted into Conversion Stock pursuant to Section 2 of this Schedule II. 

“Actual Conversion Date” means the date on which any of the outstanding balance of a Loan is converted pursuant to
Section 2 of this Schedule II. 
 “Conversion Price” means the lower of (a) $0.98 or
(b) the lowest per share selling price of any shares of capital stock sold by Borrower following the Effective Date, other than shares of capital stock sold in a transaction that would be exempt from the anti-dilution rights of the holders of
Borrower’s preferred stock pursuant to clauses (i) through (viii) of Article V, Section 5.8 of Borrower’s certificate of incorporation, as in effect on the Effective Date. The Conversion Price is subject to adjustment as
provided herein. 
 “Conversion Stock” means Borrower’s Common Stock. The number and character of shares
of Conversion Stock are subject to adjustment as provided in Section 4 of this Schedule II and the term “Conversion Stock” shall include the stock and other securities and property that are, on the Actual Conversion
Date, receivable or issuable upon such conversion of a Note in accordance with Section 4 of this Schedule II. 
 “Dividend Event” has the meaning set forth in Section 4.2 of this Schedule II. 
 “Lost Note Documentation” means documentation reasonably satisfactory to Borrower with regard to a lost or stolen Note, including, if required by Borrower, an affidavit of lost note and
an indemnification agreement by the respective Lender in favor of Borrower with respect to such lost or stolen Note. 

“Maximum Conversion Amount” means: 
 (a) with respect to any Loan comprising part of the Initial Advance, the amount of the entire outstanding balance of such Loan (including for clarity the aggregate outstanding principal and all accrued
interest and PIK Interest in respect of such Loan), and 
 (b) with respect to any Loan comprising part of a Subsequent Advance,
an amount equal to fifty percent (50%) of the initial outstanding principal amount of such Loan plus all accrued interest and PIK Interest in respect of such portion of the principal amount (the outstanding balance of the Initial Advance and
convertible portion of the Subsequent Advances being sometimes referred to herein as the “Convertible Portion of the Loans” and the non-convertible portion of the Subsequent Advances being referred to herein as the
“Non-Convertible Portion of the Loans”)); provided that if the Maturity Date occurs by reason of an IPO and either (i) Borrower is prohibited from paying, (ii) the Lenders are otherwise prohibited from receiving or
accepting payment for, or (iii) Borrower otherwise fails to pay when due the outstanding balance on any Subsequent Advance due in connection with the consummation of the IPO, including without limitation by reason of a default or event of
default under the Senior Secured Loan and Security Agreement and/or the Senior Subordinated Secured Loan and Security 

  
 1 








 
Agreement or the application of the terms of the Subordination Agreement, then the “Maximum Conversion Amount” with respect to the foregoing clause (b) shall be deemed to be one
hundred percent (100%) of the amount of the outstanding balance of such Loans. 
 “Reorganization Event”
has the meaning set forth in Section 4.3 of this Schedule II. 
 “Stock Event” has the
meaning set forth in Section 4.4 of this Schedule II. 
 2. CONVERSION. 

2.1 Optional Conversion Prior to Maturity Date. Upon the election of a Lender with respect to any Loan made by it, which election
shall be exercised by written notice from such Lender given to Borrower prior to Borrower’s repayment in full of the outstanding balance of such Loan (which election, in the event the Maturity Date is anticipated to occur due to the
consummation of a Change in Control or IPO, may at Lender’s option be made contingent upon the completion of such Change in Control or IPO), the entire Maximum Conversion Amount of such Loan, or any portion thereof as specified in such election
of the Lender, shall be cancelled and converted into that number of shares of Conversion Stock obtained by dividing (i) the entire Maximum Conversion Amount of such Loan or portion thereof specified by the Lender, by (ii) the Conversion
Price. 
 2.2 Timing of Conversion; Tender of Note or Addendum Thereto for Conversion. In connection with a conversion
pursuant to Section 2.1, a Lender shall deliver the original Note or the applicable addendum thereto corresponding to such Loan (or Lost Note Documentation, if applicable) to Borrower. If a Lender elects to convert only a portion of the
Loan represented by a Note or addendum, as the case may be, then promptly after (and in any event within 7 days after) receipt of the original Note or such addendum (or Lost Note Documentation, if applicable) Borrower shall re-issue such Lender a
new Note or addendum reflecting the portion of such Loan that was not converted and remains outstanding. If a Lender delivers written notice of an election to convert a Loan (or portion thereof) within the time period specified in
Section 2.1, the conversion of such Loan (or portion thereof) into Conversion Stock shall be deemed to occur upon the earlier of (i) the date of such Lender’s written notice (unless the Lender has elected to make conversion of
the Loan contingent on the consummation of a Change in Control or IPO) and (ii) immediately prior to the Maturity Date, without regard to whether Lender has then delivered to Borrower the Note(s) corresponding to the Loan so converted (or the
Lost Note Documentation where applicable) or executed any other documents. 
 2.3 Termination of Rights. Except for the
right to obtain certificates representing the Conversion Stock under Section 3 below, all rights with respect to a Loan (or portion thereof) converted pursuant this Section 2 shall terminate upon the effective conversion of
such Loan (or portion thereof) as provided in Section 2.1 above. 
 3. CERTIFICATES: NO FRACTIONAL SHARES.
Subject to Section 2.2 above, as soon as practicable after conversion of a Loan pursuant to Section 2.1 above, Borrower at its expense will register such shares of Conversion Stock in Borrower’s stockholder register in
the name of the applicable Lender and will cause to be issued in the name of such Lender and to be delivered to such Lender, a certificate or certificates for the number of shares of Conversion Stock to which such Lender shall be entitled upon such
conversion (bearing such legends as may be required by applicable state and federal securities laws in the opinion of legal counsel of Borrower, by Borrower’s Certificate of Incorporation and Bylaws and by any agreement between Borrower and
such Lender), together with any other securities and property to which such Lender is entitled upon such conversion under the terms of such Loan; provided that in the event that the conversion is effected upon an IPO, Borrower may issue
uncertificated shares. No fractional shares shall be issued upon conversion of a Loan. If upon any conversion of a 

  
 2 








 
Loan, a fraction of a share would otherwise be issued, then in lieu of such fractional share, Borrower shall pay to the applicable Lender an amount in cash equal to such fraction of a share
multiplied by the applicable Conversion Price. 
 4. ADJUSTMENT PROVISIONS. So long as any of the aggregate balance of
the Loans remains outstanding, the number and character of shares of Conversion Stock issuable upon conversion of a Loan upon an Actual Conversion Date and, to the extent set forth in this Section 4, the Conversion Price therefor, are
each subject to adjustment upon each occurrence of an adjustment event described in Sections 4.1 through 4.4 below occurring between the Effective Date and such Actual Conversion Date: 

4.1 Adjustment for Stock Splits and Stock Dividends. The Conversion Price and the number of shares of Conversion Stock shall each
be proportionally adjusted to reflect any stock dividend, stock split, reverse stock split or other similar event affecting the number of outstanding shares of Conversion Stock without the payment of consideration to Borrower therefor at any time
before an Actual Conversion Date. 
 4.2 Adjustment for Other Dividends and Distributions. If Borrower shall make or
issue, or shall fix a record date for the determination of eligible holders of its capital stock entitled to receive, a dividend or other distribution payable with respect to the Conversion Stock that is payable in securities of Borrower (other than
issuances with respect to which adjustment is made under Section 4.1 or 4.3 of this Schedule II), or in assets (other than cash dividends) (each, a “Dividend Event”), and such dividend or other distribution is
actually made, then, and in each such case, a Lender, upon conversion of an Actual Conversion Amount at any time after such Dividend Event, shall receive, in addition to the Conversion Stock issuable upon such conversion of its Note, the securities
or other assets that would have been issuable to such Lender had such Lender, immediately prior to such Dividend Event, converted such Actual Conversion Amount into Conversion Stock. 

4.3 Adjustment for Consolidation or Merger. If Borrower shall consolidate with or merge into one or more other corporations or
other entities (and for clarity the Loans shall not have already been repaid and/or are not being repaid in connection with the consummation of such consolidation or merger), and pursuant to such consolidation or merger stock, other securities or
other property is issued or paid to holders of Conversion Stock (each, a “Reorganization Event”), then, and in each such case, a Lender, upon conversion of an Actual Conversion Amount after the consummation of such Reorganization Event,
shall be entitled to receive (in lieu of the stock or other securities and property that such Lender would have been entitled to receive under the terms of its Note upon such conversion but for such Reorganization Event), the stock or other
securities or property that such Lender would have been entitled to receive upon the consummation of such Reorganization Event if, immediately prior to such Reorganization Event, such Lender had converted such Actual Conversion Amount into
Conversion Stock, all subject to further adjustment as provided herein, and the successor corporation or other successor entity in such Reorganization Event shall duly execute and deliver to such Lender a supplement to such Note acknowledging such
corporation’s or other entity’s obligations under such Note; and in each such case, the terms of such Note shall be applicable to the shares of stock or other securities or property receivable upon the conversion of such Note after the
consummation of such Reorganization Event. 
 4.4 Conversion of Stock. In each case not otherwise covered in
Section 4.3 above where (i) all the outstanding Conversion Stock is converted, pursuant to the terms of Borrower’s Certificate of Incorporation, into other securities or property, or (ii) the Conversion Stock otherwise
ceases to exist or to be authorized under Borrower’s Certificate of Incorporation (each a “Stock Event”), then Lender, upon conversion of this Note at any time after such Stock Event, shall receive, in lieu of the number of
shares of Conversion Stock that would have been issuable upon conversion of this Note immediately prior to such Stock Event, the stock and other securities and property that Lender would 

  
 3 








 
have been entitled to receive upon the Stock Event, if immediately prior to such Stock Event, Lender had converted the Actual Conversion Amount into Conversion Stock. 

4.5 Notice of Adjustments. Borrower shall promptly give written notice of each adjustment of the Conversion Price or the number or
type of shares of Conversion Stock or other securities or property issuable upon conversion of a Note that is required under this Section 4. The notice shall describe the adjustment or readjustment and show in reasonable detail the facts
on which the adjustment or readjustment is based. 
 4.6 Reservation of Stock. If the number of shares of Conversion
Stock or other securities authorized and reserved for issuance upon conversion of the Notes shall not be sufficient to effect the conversion of the aggregate Maximum Conversion Amounts of the Notes, then Borrower shall take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Conversion Stock or other securities issuable upon conversion of the Notes as shall be sufficient for such purpose. 

5. REPRESENTATIONS AND WARRANTIES AND COVENANTS OF THE LENDERS 
 5.1 Purchase for Own Account. Each Lender represents that it is acquiring the Notes, the Warrants, the Conversion Stock and the Common Stock, as the case may be (collectively, the
“Securities”), solely for its own account and beneficial interest for investment and not for sale or with a view to distribution of the Securities or any part thereof, has no present intention of selling (in connection with a
distribution or otherwise), granting any participation in, or otherwise distributing the same, and does not presently have reason to anticipate a change in such intention. Notwithstanding the foregoing, KPCB Holdings, Inc. is acquiring the
Securities as a nominee. 
 5.2 Information and Sophistication. Without lessening or obviating the representations and
warranties of the Borrower set forth in Section 5 of the Loan Agreement, each Lender hereby: (i) acknowledges that it has received all the information it has requested from the Borrower and it considers necessary or appropriate for
deciding whether to acquire the Securities, (ii) represents that it has had an opportunity to ask questions and receive answers from the Borrower regarding the terms and conditions of the offering of the Securities and to obtain any additional
information necessary to verify the accuracy of the information given the Lender and (iii) further represents that it has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risk of
this investment. 
 5.3 Ability to Bear Economic Risk. Each Lender acknowledges that investment in the Securities
involves a high degree of risk, and represents that it is able, without materially impairing its financial condition, to hold the Securities for an indefinite period of time and to suffer a complete loss of its investment. 

5.4 Further Limitations on Disposition. Without in any way limiting the representations set forth above, each Lender further
agrees not to make any disposition of all or any portion of the Securities unless and until: 
 (a) There is then in effect a
Registration Statement under the Act covering such proposed disposition and such disposition is made in accordance with such Registration Statement; or 
 (b) The Lender shall have notified the Borrower of the proposed disposition and shall have furnished the Borrower with a detailed statement of the circumstances surrounding the proposed disposition, and
if reasonably requested by the Borrower, such Lender shall have furnished the 

  
 4 








 
Borrower with an opinion of counsel, reasonably satisfactory to the Borrower, that such disposition will not require registration under the Act or any applicable state securities laws, provided
that no such opinion shall be required for dispositions in compliance with Rule 144, except in unusual circumstances. 

Notwithstanding the provisions of paragraphs (a) and (b) above, no such registration statement or opinion of counsel shall be
required: (i) for any transfer of any Conversion Stock, Common Stock and shares of Common Stock issued or issuable upon exercise of any Warrant in compliance with SEC Rule 144 or Rule 144A, or (ii) for any transfer of any Conversion Stock,
Common Stocker shares of Common Stock issued or issuable upon exercise of any Warrant that is a partnership, limited liability company or corporation to (A) a partner (or retired partner) or member (or retired member) of such Lender in
accordance with partnership or limited liability company interests or stock or other equity interests of such entity or (B) an Affiliate of such Lender that is a limited liability company or corporation, or (iii) for any transfers by gift,
will or intestate succession to any spouse or lineal descendants or ancestors, if all transferees agree in writing to be subject to the terms hereof to the same extent as if they were Lenders hereunder. 

5.5 Accredited Investor Status. Each Lender is an “accredited investor” as such term is defined in Rule 501 under the
Act. 
 5.7 Lock-Up Agreement. Each Lender acknowledges that the Conversion Stock, Common Stock and any shares of Common
Stock issued upon exercise of the Warrant held by such Lender shall be bound by the lock-up provisions set forth in Section 1.13 of the Amended and Restated Investors’ Rights Agreement dated as of March 15, 2010 by and between the
Borrower and certain investors in the Borrower, to which Lender, or an Affiliate of the Lender, is a party.

 SCHEDULE III 

Terms relating to Agent and Agency 
 Each of the Lenders hereby irrevocably appoints the Agent as its agent and authorizes the Agent to take such actions on its behalf and to exercise such powers as are delegated to such Agent by the terms
of the Loan Documents, together with such actions and powers as are reasonably incidental thereto. Without limiting the generality of the foregoing, the Agent is hereby expressly authorized to execute, and thereby to bind each Lender to,
(i) any and all documents (including releases) with respect to the Collateral and the rights of the Secured Parties with respect thereto, as contemplated by and in accordance with the provisions of this Agreement and the Loan Documents and
(ii) the Subordination Agreement. 
 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 an Agent, and such person and its affiliates may provide debt financing, equity capital or other services (including financial advisory services) to any of the
Lenders (or any person engaged in similar business as that engaged in by any of the Lenders) as if such person was not performing the duties specified herein, and may accept fees and other consideration from any of the Lenders for services in
connection with this Agreement and otherwise without having to account for the same to the Lenders. 
 Agent shall not have any
duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has
occurred and is continuing, (b) Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that such Agent is instructed in writing
to exercise by the Required Lenders, and (c) except as expressly set forth in the Loan Documents, Agent shall not have any duty to disclose, nor shall it be liable for the failure to disclose, any information relating to Borrower or any of the
Subsidiaries that is communicated to or obtained by the person serving as Agent and/or Collateral Agent or any of its Affiliates in any capacity. Agent shall not be liable for any action taken or not taken by it with the consent or at the request of
the Required Lenders or in the absence of its own gross negligence or willful misconduct. Agent shall not be deemed to have knowledge of any Default unless and until written notice thereof is given to such Agent by Borrower or a Lender, and 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 any Loan Document, (ii) the contents of any certificate, report or other document
delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or
genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Section 3 of the Loan Agreement or elsewhere in any Loan Document, other than to confirm receipt
of items expressly required to be delivered to such Agent. 
 Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper person. Agent may also rely upon any statement made to
it orally or by telephone and believed by it to have been made by the proper person, and shall not incur any liability for relying thereon. Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other
experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 
 Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by it. Agent and any such sub-agent may perform any and all its duties and


  
 1 








 
exercise its rights and powers by or through their respective Affiliates. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Affiliates of each
Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the Credit Facilities as well as activities as Agent. 
 Subject to the appointment and acceptance of a successor Agent as provided below, Agent may resign at any time by notifying the Lenders and the Borrower. Upon any such resignation, if no Event of Default
has occurred and is continuing, with the consent of the Borrower which shall not be unreasonably conditioned, withheld or delayed, the Required Lenders shall have the right, to appoint a successor. If no successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent which shall be one of the other
Lenders under this Agreement, or an Affiliate of any such Lender. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The Borrower shall pay the reasonable fees of a successor Agent. After an Agent’s resignation hereunder, the provisions of this Schedule
III shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Affiliates in respect of any actions taken or omitted to be taken by any of them while acting as Agent. 

Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender and based on such documents
and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender and based on such
documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement or any other Loan Document, any related agreement or any document
furnished hereunder or thereunder. 
 Each Lender hereby further authorizes Agent, on behalf of and for the ratable benefit of
Lenders, to enter into each Loan Document as secured party and to be the agent for and representative of Lenders thereunder, and each Lender agrees to be bound by the terms of each Loan Document; provided that Agent shall not (i) enter into or
consent to any material amendment, modification, termination or waiver of any provision contained in any Loan Document or (ii) release any Collateral (except as otherwise expressly permitted or required pursuant to the terms of this Agreement
or the applicable Loan Document), in each case without the prior consent of Required Lenders; provided further, however, that, without further written consent or authorization from Lenders, Agent may execute any documents or instruments
necessary to (a) release any Lien encumbering any item of Collateral that is the subject of a sale or other disposition of assets permitted by this Agreement or to which Required Lenders have otherwise consented, or (b) subordinate the
Liens of Agent, on behalf of Lenders, to any Liens permitted by the definition of Permitted Liens (other than those Liens which are the subject of the Subordination Agreement). Anything contained in any of the Loan Documents to the contrary
notwithstanding, Borrower, Agent and each Lender hereby agree that (1) no Lender shall have any right individually to realize upon any of the Collateral under or otherwise enforce any Loan Document, it being understood and agreed that all
powers, rights and remedies under the Loan Documents may be exercised solely by Agent for the ratable benefit of Lenders in accordance with the terms thereof, and (2) in the event of a foreclosure by Agent on any of the Collateral pursuant to a
public or private sale, Agent or any Lender may be the purchaser of any or all of such Collateral at any such sale and Agent, as agent for and representative of Lenders (but not any Lender or Lenders in its or their respective individual capacities
unless Required Lenders shall otherwise agree in writing) shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold at any


  
 2 








 
such public sale, to use and apply any of the Obligations as a credit on account of the purchase price for any Collateral payable by Agent at such sale.
