 1 













 
Lender, as calculated by Collateral Agent (which calculations shall be deemed correct absent manifest error) based upon: (1) the amount of such Lender’s Term Loan, (2) the
effective rate of interest, as determined in Section 2.3(a), and (3) a repayment schedule equal to (i) thirty-six (36) months, if the Term B Loans are not made hereunder and
(ii) thirty (30) months, if the Term B Loans are made hereunder. All unpaid principal and accrued and unpaid interest with respect to each Term Loan is due and payable in full on the Maturity Date. Each Term Loan may only be prepaid in
accordance with Sections 2.2(c) and 2.2(d). 
 (c) Mandatory Prepayments. If the Term Loans are accelerated
following the occurrence of an Event of Default, Borrower shall immediately pay to Lenders, payable to each Lender in accordance with its respective Pro Rata Share, an amount equal to the sum of: (i) all outstanding principal of the Term Loans
plus accrued and unpaid interest thereon through the prepayment date, (ii) the Final Payment, (iii) the Prepayment Fee, plus (iv) all other Obligations that are due and payable, including Lenders’ Expenses and interest at the
Default Rate with respect to any past due amounts. Notwithstanding (but without duplication with) the foregoing, on the Maturity Date, if the Final Payment had not previously been paid in full in connection with the prepayment of the Term Loans in

prepayment date, (B) the Final Payment, (C) the Prepayment Fee, plus (D) all other Obligations that are due and payable, including Lenders’ Expenses and interest at the Default Rate with respect to any past due amounts. 

 

	2.3	 Payment of Interest on the Credit Extensions. 



(a) Interest Rate. Subject to Section 2.3(b), the principal amount outstanding under the Term Loans shall accrue
interest at a floating per annum rate equal to the Basic Rate, determined by Collateral Agent on the Funding Date of the applicable Term Loan and then monthly thereafter, which interest shall be payable monthly in arrears in accordance with Sections
2.2(b) and 2.3(e). Interest shall accrue on each Term Loan commencing on, and including, the Funding Date of such Term Loan, and shall accrue on the principal amount outstanding under such Term Loan through and including the day on which such
Term Loan is paid in full. 
 (b) Default Rate. Immediately upon the occurrence and during the continuance of an Event
of Default, Obligations shall accrue interest at a floating per annum rate equal to the rate that is otherwise applicable thereto plus five percentage points (5.00%) (the “Default Rate”). Payment or acceptance of the increased
interest rate provided in this Section 2.3(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Collateral Agent. 

(c) 360-Day Year. Interest shall be computed on the basis of a three
hundred sixty (360) day year, and the actual number of days elapsed. 
 (d) Debit of Accounts. Collateral Agent
and each Lender may debit (or ACH) any deposit accounts, maintained by Borrower or any of its Subsidiaries, including the Designated Deposit Account, for principal and interest payments or any other amounts Borrower owes the Lenders under the Loan
Documents when due. Any such debits (or ACH activity) shall not constitute a set-off. 

(e) Payments. Except as otherwise expressly provided herein, all payments by Borrower under the Loan Documents shall be
made to the respective Lender to which such payments are owed, at such Lender’s office in immediately available funds on the date specified herein. Unless otherwise provided, interest is payable monthly on the Payment Date of each month.
Payments of principal and/or interest received after 12:00 noon Eastern time are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment is due the next Business
Day and additional fees or interest, as applicable, shall continue to accrue until paid. All payments to be made by Borrower hereunder or under any other Loan Document, including payments of principal and interest, and all fees, expenses,
indemnities and reimbursements, shall be made without set-off, recoupment or counterclaim, in lawful money of the United States and in immediately available funds.

 2.4 Secured Promissory Notes. The Term Loans shall be
evidenced by a Secured Promissory Note or Notes in the form attached as Exhibit D hereto (each a “Secured Promissory Note”), and shall be repayable as set forth in this Agreement. Borrower irrevocably
authorizes each Lender to make or cause to be made, on or about the Funding Date of any Term Loan or at the time of receipt of any payment of principal on such Lender’s Secured Promissory Note, an appropriate notation on such Lender’s
Secured Promissory Note Record reflecting the making of such Term Loan or (as the case may be) the receipt of such payment. The outstanding amount of each Term Loan set forth on such Lender’s Secured Promissory Note Record shall be prima facie
evidence of the principal amount thereof owing and unpaid to such Lender, but the failure to record, or any error in so recording, any such amount on such Lender’s Secured Promissory Note Record shall not limit or otherwise affect the
obligations of Borrower under any Secured Promissory Note or any other Loan Document to make payments of principal of or interest on any Secured Promissory Note when due. Upon receipt of an affidavit of an officer of a Lender as to the loss, theft,
destruction, or mutilation of its Secured Promissory Note, Borrower shall issue, in lieu thereof, a replacement Secured Promissory Note in the same principal amount thereof and of like tenor. 

2.5 Fees. Borrower shall pay to Collateral Agent: 

(a) Facility Fee. A fully earned, non-refundable facility fee of Seventy Five
Thousand Dollars ($75,000.00) to be shared between the Lenders pursuant to their respective Commitment Percentages payable on the Effective Date; 

(b) Good Faith Deposit. An amount of Thirty Thousand Dollars ($30,000.00) has been received by Collateral Agent as good
faith deposit from Borrower on or about June 27, 2017, which amount shall be applied towards the facility fee due under Section 2.5(a) hereof on the Effective Date. For the purposes of clarity, Borrower shall be responsible for the entire
amount of facility fee payable pursuant to Section 2.5(a) hereof. 
 (c) Final Payment. The Final Payment, when
due hereunder, to be shared between the Lenders in accordance with their respective Pro Rata Shares; 
 (d) Prepayment
Fee. The Prepayment Fee, when due hereunder, to be shared between the Lenders in accordance with their respective Pro Rata Shares; and 

(e) Lenders’ Expenses. All Lenders’ Expenses (including reasonable attorneys’ fees and expenses for
documentation and negotiation of this Agreement) incurred through and after the Effective Date, when due. 
 2.6
Withholding. Payments received by the Lenders from Borrower hereunder will be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, duties, deductions, withholdings, assessments, fees or other
charges imposed by any governmental authority (including any interest, additions to tax or penalties applicable thereto). Specifically, however, if at any time any Governmental Authority, applicable law, regulation or international agreement
requires Borrower to make any withholding or deduction from any such payment or other sum payable hereunder to the Lenders, Borrower hereby covenants and agrees that the amount due from Borrower with respect to such payment or other sum payable
hereunder will be increased to the extent necessary to ensure that, after the making of such required withholding or deduction, each Lender receives a net sum equal to the sum which it would have received had no withholding or deduction been
required and Borrower shall pay the full amount withheld or deducted to the relevant Governmental Authority. Borrower will, upon request, furnish the Lenders with proof reasonably satisfactory to the Lenders indicating that Borrower has made such
withholding payment; provided, however, that Borrower need not make any withholding payment if the amount or validity of such withholding payment is contested in good faith by appropriate and timely proceedings and as to which payment in full is
bonded or reserved against by Borrower. The agreements and obligations of Borrower contained in this Section 2.6 shall survive the termination of this Agreement.

	4.	 CREATION OF SECURITY INTEREST 



4.1 Grant of Security Interest. Borrower hereby grants Collateral Agent, for the ratable benefit of the Lenders,
to secure the payment and performance in full of all of the Obligations, a continuing security interest in, and pledges to Collateral Agent, for the ratable benefit of the Lenders, the Collateral, wherever located, whether now owned or hereafter
acquired or arising, and all proceeds and products thereof. Borrower represents, warrants, and 

  
 5 













 
covenants that the security interest granted herein is and shall at all times continue to be a first priority perfected security interest in the Collateral, subject only to Permitted Liens that
are permitted by the terms of this Agreement to have priority to Collateral Agent’s Lien, subject to exceptions in the Cayman Debenture, dated as of the date hereof, between the Collateral Agent and Cayman Sub. If Borrower shall acquire a
commercial tort claim (as defined in the Code), Borrower, shall promptly notify Collateral Agent in a writing signed by Borrower, after Borrower becomes aware of such tort claim, as the case may be, of the general details thereof (and further
details as may be required by Collateral Agent) and grant to Collateral Agent, for the ratable benefit of the Lenders, 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 reasonably satisfactory to Collateral Agent. 
 If this Agreement is terminated, Collateral
Agent’s Lien in the Collateral shall continue until the Obligations (other than inchoate indemnity obligations) are repaid in full in cash. Upon payment in full in cash of the Obligations (other than inchoate indemnity obligations) and at such
time as the Lenders’ obligation to make Credit Extensions has terminated, Collateral Agent shall, at the sole cost and expense of Borrower, release its Liens in the Collateral and all rights therein shall revert to Borrower. 

4.2 Authorization to File Financing Statements. Borrower hereby authorizes Collateral Agent to file financing
statements or take any other action required to perfect Collateral Agent’s security interests in the Collateral, without notice to Borrower, with all appropriate jurisdictions to perfect or protect Collateral Agent’s interest or rights
under the Loan Documents, including a notice that any disposition of the Collateral, except to the extent permitted by the terms of this Agreement, by Borrower, or any other Person, shall be deemed to violate the rights of Collateral Agent under the
Code. The Borrower shall also ensure that the register of mortgages and charges of Cayman Sub maintained at its registered office shall be updated to reflect each security grant under the Loan Documents. 

4.3 Pledge of Collateral. Borrower hereby pledges, assigns and grants to Collateral Agent, for the ratable
benefit of the Lenders, a security interest in all the Shares, together with all proceeds and substitutions thereof, all cash, stock and other moneys and property paid thereon, all rights to subscribe for securities declared or granted in connection
therewith, and all other cash and noncash proceeds of the foregoing, as security for the performance of the Obligations. On the Effective Date, or, to the extent not certificated as of the Effective Date, within ten (10) days of the
certification of any Shares, the certificate or certificates for the Shares (if any) will be delivered to Collateral Agent, accompanied by an instrument of assignment or share transfer form duly executed in blank by Borrower. To the extent required
by the terms and conditions governing the Shares, Borrower shall cause the books (or register of members, as applicable) of each entity whose Shares are part of the Collateral and any transfer agent to reflect the pledge of the Shares. Upon the
occurrence and during the continuance of an Event of Default hereunder, Collateral Agent may effect the transfer of any securities included in the Collateral (including but not limited to the Shares) into the name of Collateral Agent and cause new
(as applicable) certificates representing such securities to be issued in the name of Collateral Agent or its transferee. Borrower will execute and deliver such documents, and take or cause to be taken such actions, as Collateral Agent may
reasonably request to perfect or continue the perfection of Collateral Agent’s security interest in the Shares. Unless an Event of Default shall have occurred and be continuing, Borrower shall be entitled to exercise any voting rights with
respect to the Shares and to give consents, waivers and ratifications in respect thereof, provided that no vote shall be cast or consent, waiver or ratification given or action taken which would be inconsistent with any of the terms of this
Agreement or which would constitute or create any violation of any of such terms. All such rights to vote and give consents, waivers and ratifications shall terminate upon the occurrence and continuance of an Event of Default.

(a) Maintain all of Borrower’s Collateral Accounts in accounts which are subject to a Control Agreement in favor of
Collateral Agent, which Control Agreement must be in such form and substances as is reasonably acceptable to Collateral Agent (it being agreed and understood that the Control Agreements that Collateral Agent is entering into with respect to
Borrower’s Collateral Accounts maintained with Bank of America on the Effective Date are not in such form and substance as is not reasonably satisfactory to Collateral Agent). 

(b) Borrower shall provide Collateral Agent five (5) days’ prior written notice before Borrower or any of its

Collateral Agent by Borrower as such in the Perfection Certificates and (ii) BofA Credit Card Account so long as such account is maintained exclusively for the purpose of securitizing Borrower’s Indebtedness described in clause (g) of

(c) Neither Borrower nor any of its Subsidiaries shall maintain any Collateral Accounts except Collateral Accounts maintained
in accordance with Sections 6.6(a) and (b); provided, however, Borrower may continue to maintain its Collateral Accounts, set forth on the Perfection Certificates on the Effective Date, with Bank of America; provided, further, that Borrower
shall close all of its Collateral Accounts maintained with Bank of America on the Effective Date (other than the BofA Credit Card Account) and deliver to Collateral Agent evidence (in such form and substance as is reasonably acceptable to Collateral

proceeding instituted by or against Collateral Agent or any Lender with respect to any Collateral or relating to Borrower. 

6.9 Notices of Litigation and Default. Borrower will give prompt written notice to Collateral Agent and the
Lenders of any litigation or governmental proceedings pending or threatened (in writing) against Borrower or any of its Subsidiaries, which could reasonably be expected to result in damages or costs to Borrower or any of its


  
 12 













 
Subsidiaries of One Hundred Fifty Thousand Dollars ($150,000.00) or more or which could reasonably be expected to have a Material Adverse Change. Without limiting or contradicting any other more
specific provision of this Agreement, promptly (and in any event within three (3) Business Days) upon Borrower becoming aware of the existence of any Event of Default or event which, with the giving of notice or passage of time, or both, would
constitute an Event of Default, Borrower shall give written notice to Collateral Agent and the Lenders of such occurrence, which such notice shall include a reasonably detailed description of such Event of Default or event which, with the giving of
notice or passage of time, or both, would constitute an Event of Default. 
 6.10 Landlord Waivers; Bailee
Waivers. In the event that Borrower or any of its Subsidiaries that are Loan Parties, after the Effective Date, intends to add any new offices or business locations, including warehouses, or otherwise store any portion of the Collateral
constituting of the books and records of the Borrower or any of its Subsidiaries or having an aggregate book value in excess of Two Hundred Fifty Thousand Dollars ($250,000.00) (other than at storage facilities or withcontract manufacturers or at
clinical sites, in which case the Collateral must comprise only of non-commercial clinical compounds), or deliver any portion of the Collateral to, a bailee, in each case pursuant to Section 7.2, then
Borrower or such Loan Party will first receive the written consent of Collateral Agent and, in the event that the new location is the chief executive office of the Borrower or such Loan Party or the Collateral at any such new location is valued in
excess of exceed Two Hundred Fifty Thousand Dollars in the aggregate or constituting of the books and records of the Borrower or any Loan Party, such bailee or landlord, as applicable, must execute and deliver a bailee waiver or landlord waiver, as
applicable, in form and substance reasonably satisfactory to Collateral Agent prior to the addition of any new offices or business locations, or any such storage with or delivery to any such bailee, as the case may be. 

6.11 Creation/Acquisition of Subsidiaries. In the event Borrower, or any of its Subsidiaries creates or acquires
any Subsidiary, Borrower shall provide prior written notice to Collateral Agent and each Lender of the creation or acquisition of such new Subsidiary and take all such action as may be reasonably required by Collateral Agent or any Lender to cause
each such Subsidiary to become a co-Borrower hereunder or to guarantee the Obligations of Borrower under the Loan Documents and, in each case, grant a continuing pledge and security interest in and to the
assets of such Subsidiary (substantially as described on Exhibit A hereto); and Borrower (or its Subsidiary, as applicable) shall grant and pledge to Collateral Agent, for the ratable benefit of the Lenders, a perfected
security interest in the Shares; provided, however, that solely in the circumstance in which Borrower or any Subsidiary creates or acquires a Foreign Subsidiary in an acquisition permitted by Section 7.7 hereof or otherwise approved by the
Required Lenders, (i) such Foreign Subsidiary shall not be required to guarantee the Obligations of Borrower under the Loan Documents and grant a continuing pledge and security interest in and to the assets of such Foreign Subsidiary, and
(ii) Borrower shall not be required to grant and pledge to Collateral Agent, for the ratable benefit of Lenders, a perfected security interest in more than sixty-five percent (65%) of the Shares of such
Foreign Subsidiary, if Borrower demonstrates to the reasonable satisfaction of Collateral Agent that such Foreign Subsidiary providing such guarantee or pledge and security interest or Borrower providing a perfected security interest in more than sixty-five percent (65%) of the Shares would create a present and existing adverse tax consequence to Borrower under the U.S. Internal Revenue Code. 

6.12 Further Assurances. 

(a) Execute any further instruments and take further action as Collateral Agent or any Lender reasonably requests to perfect or
continue Collateral Agent’s Lien in the Collateral or to effect the purposes of this Agreement. 
 (b) Deliver to
Collateral Agent and Lenders, within five (5) days after the same are sent or received, copies of all material correspondence, reports, documents and other filings with any Governmental Authority that could reasonably be expected to have a

with any Affiliate of Borrower or any of its Subsidiaries, except for (a) transactions that are in the ordinary course of Borrower’s or such Subsidiary’s business, upon fair and reasonable terms that are no less favorable to Borrower

the ten (10) day period or cannot after diligent attempts by Borrower be cured within such ten (10) day period, and such default is likely to be cured within a reasonable time, then Borrower shall have an additional period (which shall not
in any case exceed thirty (30) days) to attempt to cure such default, and within such reasonable time period the failure to cure the default shall not be deemed an Event of Default (but no Credit Extensions shall be made during such cure
period). Grace periods provided under this Section shall not apply, among other things, to financial covenants or any other covenants set forth in subsection (a) above;

forty-five (45) days (but no Credit Extensions shall be made while Borrower or any Subsidiary is Insolvent and/or until any Insolvency Proceeding is dismissed); 

8.6 Other Agreements. There is a default in any agreement to which Borrower or any of its Subsidiaries is a party
with a third party or parties resulting in a right by such third party or parties, whether or not exercised, to accelerate the maturity of any Indebtedness in an amount in excess of Two Hundred Fifty Thousand Dollars ($250,000.00) or that could
reasonably be expected to have a Material Adverse Change; provided, however, that the Event of Default under this Section 8.6 caused by the occurrence of a breach or default under such other agreement shall be cured or waived for purposes of
this Agreement upon Collateral Agent receiving written notice from the party asserting such breach or default of such cure or waiver of the breach or default under such other agreement, if at the time of such cure or waiver under such other
agreement (x) Collateral Agent or any Lender has not declared an Event of Default under this Agreement and/or exercised any rights with respect thereto; (y) any such cure or waiver does not result in an Event of Default under any other
provision of this Agreement or any Loan Document; and (z) in connection with any such cure or waiver under such other agreement, the terms of any agreement with such third party are not modified or amended in any manner which could in the good
faith business judgment of Collateral Agent be materially less advantageous to Borrower; 
 8.7 Judgments. One
or more judgments, orders, or decrees for the payment of money in an amount, individually or in the aggregate, of at least Two Hundred Fifty Thousand Dollars ($250,000.00) (not covered by independent
third-party insurance as to which liability has been accepted by such insurance carrier) shall be rendered against Borrower or any of its Subsidiaries and shall remain unsatisfied, unvacated, or unstayed for a
period of ten (10) days after the entry thereof (provided that no Credit Extensions will be made prior to the satisfaction, vacation, or stay of such judgment, order or decree); 

8.8 Misrepresentations. Borrower or any of its Subsidiaries or any Person acting for Borrower or any of its
Subsidiaries makes any representation, warranty, or other statement now or later in this Agreement, any Loan Document or in any writing delivered to Collateral Agent and/or Lenders or to induce Collateral Agent and/or the Lenders to enter this

Lenders breaches any terms of such agreement;

expected to result in a Material Adverse Change; or 
 8.12 Lien Priority. Any Lien created hereunder or by any
other Loan Document shall at any time fail to constitute a valid and perfected Lien on any of the Collateral purported to be secured thereby, subject to no prior or equal Lien, other than Permitted Liens which are permitted to have priority in
accordance with the terms of this Agreement.

 9. RIGHTS AND REMEDIES 

9.1 Rights and Remedies. 

(a) Upon the occurrence and during the continuance of an Event of Default, Collateral Agent may, and at the written direction
of Required Lenders shall, without notice or demand, do any or all of the following: (i) deliver notice of the Event of Default to Borrower, (ii) by notice to Borrower declare all Obligations immediately due and payable (but if an
Event of Default described in Section 8.5 occurs all Obligations shall be immediately due and payable without any action by Collateral Agent or the Lenders) or (iii) by notice to Borrower suspend or terminate the obligations, if any, of
the Lenders to advance money or extend credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Collateral Agent and/or the Lenders (but if an Event of Default described in Section 8.5 occurs all
obligations, if any, of the Lenders to advance money or extend credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Collateral Agent and/or the Lenders shall be immediately terminated without any
action by Collateral Agent or the Lenders). 
 (b) Without limiting the rights of Collateral Agent and the Lenders set forth
in Section 9.1(a) above, upon the occurrence and during the continuance of an Event of Default, Collateral Agent shall have the right, without notice or demand, to do any or all of the following: 

(i) foreclose upon and/or sell or otherwise liquidate, the Collateral; 

(ii) apply to the Obligations any (a) balances and deposits of Borrower that Collateral Agent or any Lender holds or
controls, or (b) any amount held or controlled by Collateral Agent or any Lender owing to or for the credit or the account of Borrower; and/or 

(iii) commence and prosecute an Insolvency Proceeding or consent to Borrower commencing any Insolvency Proceeding. 

(c) Without limiting the rights of Collateral Agent and the Lenders set forth in Sections 9.1(a) and (b) above, upon
the occurrence and during the continuance of an Event of Default, Collateral Agent shall have the right, without notice or demand, to do any or all of the following: 

(i) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Collateral
Agent considers advisable, notify any Person owing Borrower money of Collateral Agent’s security interest in such funds, and verify the amount of such account; 

(ii) make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its security
interest in the Collateral. Borrower shall assemble the Collateral if Collateral Agent requests and make it available in a location as Collateral Agent reasonably designates. Collateral Agent may enter premises where the Collateral is located, take
and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Collateral Agent a license to
enter and occupy any of its premises, without charge, to exercise any of Collateral Agent’s rights or remedies; 

(iii) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, and/or advertise for sale, the Collateral.
Collateral Agent is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s and each of its Subsidiaries’
labels, patents, copyrights, mask works, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in completing production of, advertising for
sale, and selling any Collateral and, in connection with Collateral Agent’s exercise of its rights under this Section 9.1, Borrower’s and each of its Subsidiaries’ rights under all licenses and all franchise agreements inure to
Collateral Agent, for the benefit of the Lenders; 

  
 18 













 (iv) place a “hold” on any account maintained with Collateral
Agent or the Lenders and/or deliver a notice of exclusive control, any entitlement order, or other directions or instructions pursuant to any Control Agreement or similar agreements providing control of any Collateral; 

(v) demand and receive possession of Borrower’s Books; 

(vi) appoint a receiver to seize, manage and realize any of the Collateral, and such receiver shall have any right and
authority as any competent court will grant or authorize in accordance with any applicable law, including any power or authority to manage the business of Borrower or any of its Subsidiaries; and 

(vii) subject to clauses 9.1(a) and (b), exercise all rights and remedies available to Collateral Agent and each Lender
under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof). 

Notwithstanding any provision of this Section 9.1 to the contrary, upon the occurrence of any Event of Default, Collateral Agent shall
have the right to exercise any and all remedies referenced in this Section 9.1 without the written consent of Required Lenders following the occurrence of an Exigent Circumstance. As used in the immediately preceding sentence, “Exigent
Circumstance” means any event or circumstance that, in the reasonable judgment of Collateral Agent, imminently threatens the ability of Collateral Agent to realize upon all or any material portion of the Collateral, such as, without
limitation, fraudulent removal, concealment, or abscondment thereof, destruction or material waste thereof, or failure of Borrower or any of its Subsidiaries after reasonable demand to maintain or reinstate adequate casualty insurance coverage, or
which, in the judgment of Collateral Agent, could reasonably be expected to result in a material diminution in value of the Collateral. 

9.2 Power of Attorney. Borrower hereby irrevocably appoints Collateral Agent as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s or any of its Subsidiaries’ name
on any checks or other forms of payment or security; (b) sign Borrower’s or any of its Subsidiaries’ name on any invoice or bill of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and
claims about the Accounts directly with Account Debtors, for amounts and on terms Collateral Agent determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies; (e) pay, contest or settle any
Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of Collateral
Agent or a third party as the Code or any applicable law permits. Borrower hereby appoints Collateral Agent as its lawful attorney-in-fact to sign Borrower’s or any
of its Subsidiaries’ name on any documents necessary to perfect or continue the perfection of Collateral Agent’s security interest in the Collateral regardless of whether an Event of Default has occurred until all Obligations (other than
inchoate indemnity obligations) have been satisfied in full and Collateral Agent and the Lenders are under no further obligation to make Credit Extensions hereunder. Collateral Agent’s foregoing appointment as Borrower’s or any of its
Subsidiaries’ attorney in fact, and all of Collateral Agent’s rights and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate indemnity obligations) have been fully repaid and performed and
Collateral Agent’s and the Lenders’ obligation to provide Credit Extensions terminates. 
 9.3 Protective
Payments. If Borrower or any of its Subsidiaries fail to obtain the insurance called for by Section 6.5 or fails to pay any premium thereon or fails to pay any other amount which Borrower or any of its Subsidiaries is obligated to pay under
this Agreement or any other Loan Document, Collateral Agent may obtain such insurance or make such payment, and all amounts so paid by Collateral Agent are Lenders’ Expenses and immediately due and payable, bearing interest at the Default Rate,
and secured by the Collateral. Collateral Agent will make reasonable efforts to provide Borrower with notice of Collateral Agent obtaining such insurance or making such payment at the time it is obtained or paid or within a reasonable time
thereafter. No such payments by Collateral Agent are deemed an agreement to make similar payments in the future or Collateral Agent’s waiver of any Event of Default. 

9.4 Application of Payments and Proceeds. Notwithstanding anything to the contrary contained in this Agreement,
upon the occurrence and during the continuance of an Event of Default, (a) Borrower irrevocably waives the right to direct the application of any and all payments at any time or times thereafter received by


  
 19 













 
Collateral Agent from or on behalf of Borrower or any of its Subsidiaries of all or any part of the Obligations, and, as between Borrower on the one hand and Collateral Agent and Lenders on the
other, Collateral Agent shall have the continuing and exclusive right to apply and to reapply any and all payments received against the Obligations in such manner as Collateral Agent may deem advisable notwithstanding any previous application by
Collateral Agent, and (b) the proceeds of any sale of, or other realization upon all or any part of the Collateral shall be applied: first, to the Lenders’ Expenses; second, to accrued and unpaid interest on the Obligations (including any
interest which, but for the provisions of the United States Bankruptcy Code, would have accrued on such amounts); third, to the principal amount of the Obligations outstanding; and fourth, to any other indebtedness or obligations of Borrower owing
to Collateral Agent or any Lender under the Loan Documents. Any balance remaining shall be delivered to Borrower or to whoever may be lawfully entitled to receive such balance or as a court of competent jurisdiction may direct. In carrying out the
foregoing, (x) amounts received shall be applied in the numerical order provided until exhausted prior to the application to the next succeeding category, and (y) each of the Persons entitled to receive a payment in any particular category
shall receive an amount equal to its pro rata share of amounts available to be applied pursuant thereto for such category. Any reference in this Agreement to an allocation between or sharing by the Lenders of any right, interest or obligation
“ratably,” “proportionally” or in similar terms shall refer to Pro Rata Share unless expressly provided otherwise. Collateral Agent, or if applicable, each Lender, shall promptly remit to the other Lenders such sums as may be
necessary to ensure the ratable repayment of each Lender’s portion of any Term Loan and the ratable distribution of interest, fees and reimbursements paid or made by Borrower. Notwithstanding the foregoing, a Lender receiving a scheduled
payment shall not be responsible for determining whether the other Lenders also received their scheduled payment on such date; provided, however, if it is later determined that a Lender received more than its ratable share of scheduled payments made
on any date or dates, then such Lender shall remit to Collateral Agent or other Lenders such sums as may be necessary to ensure the ratable payment of such scheduled payments, as instructed by Collateral Agent. If any payment or distribution of any
kind or character, whether in cash, properties or securities, shall be received by a Lender in excess of its ratable share, then the portion of such payment or distribution in excess of such Lender’s ratable share shall be received by such
Lender in trust for and shall be promptly paid over to the other Lender for application to the payments of amounts due on the other Lenders’ claims. To the extent any payment for the account of Borrower is required to be returned as a voidable
transfer or otherwise, the Lenders shall contribute to one another as is necessary to ensure that such return of payment is on a pro rata basis. If any Lender shall obtain possession of any Collateral, it shall hold such Collateral for itself and as
agent and bailee for Collateral Agent and other Lenders for purposes of perfecting Collateral Agent’s security interest therein. 

9.5 Liability for Collateral. So long as Collateral Agent and the Lenders comply with reasonable banking
practices regarding the safekeeping of the Collateral in the possession or under the control of Collateral Agent and the Lenders, Collateral Agent and the Lenders shall not be liable or responsible for: (a) the safekeeping of the Collateral;
(b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Borrower bears all risk of loss, damage or destruction of
the Collateral. 
 9.6 No Waiver; Remedies Cumulative. Failure by Collateral Agent or any Lender, at any time
or times, to require strict performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Collateral Agent or any Lender thereafter to demand strict performance and compliance
herewith or therewith. No waiver hereunder shall be effective unless signed by Collateral Agent and the Required Lenders and then is only effective for the specific instance and purpose for which it is given. The rights and remedies of Collateral
Agent and the Lenders under this Agreement and the other Loan Documents are cumulative. Collateral Agent and the Lenders have all rights and remedies provided under the Code, any applicable law, by law, or in equity. The exercise by Collateral Agent
or any Lender of one right or remedy is not an election, and Collateral Agent’s or any Lender’s waiver of any Event of Default is not a continuing waiver. Collateral Agent’s or any Lender’s delay in exercising any remedy is not a
waiver, election, or acquiescence. 
 9.7 Demand Waiver. Borrower waives, to the fullest extent permitted by
law, demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees
held by Collateral Agent or any Lender on which Borrower or any Subsidiary is liable.

	11.	 CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER, AND JUDICIAL REFERENCE 



California law governs the Loan Documents without regard to principles of conflicts of law. Borrower, Collateral Agent and each
Lender each submit to the exclusive jurisdiction of the State and Federal courts in Santa Clara County, California; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Collateral Agent or any Lender from bringing
suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Collateral Agent or any Lender. Borrower expressly submits
and consents in advance to such jurisdiction in any 

  
 21 













 
action or suit commenced in any such court, and Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby
consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Borrower hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such
summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in, or subsequently provided by Borrower in accordance with, Section 10 of this Agreement and that service so made
shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid. 

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER, COLLATERAL AGENT AND EACH LENDER EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY
CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR EACH PARTY TO ENTER
INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 
 WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES’
AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time
shall be decided by a reference to a private judge, mutually selected by the parties (or, if they cannot agree, by the Presiding Judge of the Santa Clara County, California Superior Court) appointed in accordance with California Code of Civil
Procedure Section 638 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts), sitting without a jury, in Santa Clara County, California; and the parties hereby submit
to the jurisdiction of such court. The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the
power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers. All such proceedings shall be closed to the public and
confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference
procedures, then such party may apply to the Santa Clara County, California Superior Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence
applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee
discovery and may enforce all discovery rules and orders applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the
action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this
paragraph. 
  

	12.	 GENERAL PROVISIONS 



12.1 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns
of each party. Borrower may not transfer, pledge or assign this Agreement or any rights or obligations under it without Collateral Agent’s and each Lender’s prior written consent (which may be granted or withheld in Collateral Agent’s
and each Lender’s discretion, subject to Section 12.6). The Lenders have the right, without the consent of or notice to Borrower, to sell, transfer, assign, pledge, negotiate, or grant participation in (any such sale, transfer,
assignment, negotiation, or grant of a participation, a “Lender Transfer”) all or any part of, or any interest in, the Lenders’ obligations, rights, and benefits under this Agreement and the other
Loan Documents; provided, however, that any such Lender Transfer (other than a transfer, pledge, sale or assignment to an Eligible Assignee) of its obligations, rights, and benefits under this Agreement and the other Loan
Documents shall require the prior written consent of the Required Lenders (such approved assignee, an “Approved Lender”). Borrower and Collateral Agent shall be entitled to continue to deal solely and directly with such
Lender in connection with the interests so assigned until Collateral Agent shall have received and accepted an effective assignment agreement in 

  
 22 













 
form satisfactory to Collateral Agent executed, delivered and fully completed by the applicable parties thereto, and shall have received such other information regarding such Eligible Assignee or
Approved Lender as Collateral Agent reasonably shall require. Notwithstanding anything to the contrary contained herein, so long as no Event of Default has occurred and is continuing, no Lender Transfer (other than a Lender Transfer (i) in
respect of the Warrants or (ii) in connection with (x) assignments by a Lender due to a forced divestiture at the request of any regulatory agency; or (y) upon the occurrence of a default, event of default or similar occurrence with
respect to a Lender’s own financing or securitization transactions) shall be permitted, without Borrower’s consent, to any Person which is an Affiliate or Subsidiary of Borrower, a direct competitor of Borrower or a vulture hedge fund,
each as determined by Collateral Agent. 
 12.2 Indemnification. Borrower agrees to indemnify, defend and hold
Collateral Agent and the Lenders and their respective directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Collateral Agent or the Lenders (each, an “Indemnified Person”) harmless
against: (a) all obligations, demands, claims, and liabilities (collectively, “Claims”) asserted by any other party in connection with; related to; following; or arising from, out of or under, the transactions contemplated by
the Loan Documents; and (b) all losses or Lenders’ Expenses incurred, or paid by Indemnified Person in connection with; related to; following; or arising from, out of or under, the transactions contemplated by the Loan Documents between
Collateral Agent, and/or the Lenders and Borrower (including reasonable attorneys’ fees and expenses), except for Claims and/or losses directly caused by such Indemnified Person’s gross negligence or willful misconduct. Borrower hereby
further indemnifies, defends and holds each Indemnified Person harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and disbursements of any kind or nature
whatsoever (including the fees and disbursements of counsel for such Indemnified Person) in connection with any investigative, response, remedial, administrative or judicial matter or proceeding, whether or not such Indemnified Person shall be
designated a party thereto and including any such proceeding initiated by or on behalf of Borrower, and the reasonable expenses of investigation by engineers, environmental consultants and similar technical personnel and any commission, fee or
compensation claimed by any broker (other than any broker retained by Collateral Agent or Lenders) asserting any right to payment for the transactions contemplated hereby which may be imposed on, incurred by or asserted against such Indemnified
Person as a result of or in connection with the transactions contemplated hereby and the use or intended use of the proceeds of the loan proceeds except for liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims,
costs, expenses and disbursements directly caused by such Indemnified Person’s gross negligence or willful misconduct. 

12.3 Time of Essence. Time is of the essence for the performance of all Obligations in this Agreement. 

12.4 Severability of Provisions. Each provision of this Agreement is severable from every other provision in
determining the enforceability of any provision. 
 12.5 Correction of Loan Documents. Collateral Agent and the Lenders
may correct patent errors and fill in any blanks in this Agreement and the other Loan Documents consistent with the agreement of the parties. 

12.6 Amendments in Writing; Integration. (a) No amendment, modification, termination or waiver of any
provision of this Agreement or any other Loan Document, no approval or consent thereunder, or any consent to any departure by Borrower or any of its Subsidiaries therefrom, shall in any event be effective unless the same shall be in writing and
signed by Borrower, Collateral Agent and the Required Lenders provided that: 
 (i) no such amendment, waiver or other
modification that would have the effect of increasing or reducing a Lender’s Term Loan Commitment or Commitment Percentage shall be effective as to such Lender without such Lender’s written consent; 

(ii) no such amendment, waiver or modification that would affect the rights and duties of Collateral Agent shall be effective
without Collateral Agent’s written consent or signature; 
 (iii) no such amendment, waiver or other modification
shall, unless signed by all the Lenders directly affected thereby, (A) reduce the principal of, rate of interest on or any fees with respect to any Term Loan or forgive any principal, interest (other than default interest) or fees (other than
late charges) with respect 

  
 23 













 
to any Term Loan (B) postpone the date fixed for, or waive, any payment of principal of any Term Loan or of interest on any Term Loan (other than default interest) or any fees provided for
hereunder (other than late charges or for any termination of any commitment); (C) change the definition of the term “Required Lenders” or the percentage of Lenders which shall be required for the Lenders to take any action
hereunder; (D) release all or substantially all of any material portion of the Collateral, authorize Borrower to sell or otherwise dispose of all or substantially all or any material portion of the Collateral or release any Guarantor of all or
any portion of the Obligations or its guaranty obligations with respect thereto, except, in each case with respect to this clause (D), as otherwise may be expressly permitted under this Agreement or the other Loan Documents (including in connection

or any other Person now or hereafter primarily or secondarily liable for any of the Obligations, for 

  
 25 













 
any payment made by Borrower with respect to the Obligations in connection with this Agreement or otherwise and all rights that it might have to benefit from, or to participate in, any security
for the Obligations as a result of any payment made by Borrower with respect to the Obligations in connection with this Agreement or otherwise. Any agreement providing for indemnification, reimbursement or any other arrangement prohibited under this
Section shall be null and void. If any payment is made to a Borrower in contravention of this Section, such Borrower shall hold such payment in trust for Collateral Agent and the Lenders and such payment shall be promptly delivered to

All Borrower’s Books relating to the foregoing, and any and all claims, rights and interests in any of the above and all

Notwithstanding the foregoing, the Collateral does not include (i) any Intellectual Property; provided, however, the
Collateral shall include all Accounts and all proceeds of Intellectual Property. If a judicial authority (including a U.S. Bankruptcy Court) would hold that a security interest in the underlying Intellectual Property is necessary to have a security
interest in such Accounts and such property that are proceeds of Intellectual Property, then the Collateral shall automatically, and effective as of the Effective Date, include the Intellectual Property to the extent necessary to permit perfection
of Collateral Agent’s security interest in such Accounts and such other property of Borrower that are proceeds of the Intellectual Property; (ii) more than 65% of the total combined voting power of all classes of stock entitled to vote the
shares of capital stock (the “Shares”) of any Foreign Subsidiary, if Borrower demonstrates to Collateral Agent’s reasonable satisfaction that a pledge of more than sixty five percent (65%) of the Shares of such Subsidiary creates a
present and existing adverse tax consequence to Borrower under the U.S. Internal Revenue Code; the (iii) BofA Credit Card Account and (iv) any license or contract, in each case if the granting of a Lien in such license or contract is
prohibited by or would constitute a default under the agreement governing such license or contract (but (A) only to the extent such prohibition is enforceable under applicable law and (B) other than to the extent that any such term would
be rendered ineffective pursuant to Sections 9-406, 9-408 or 9-409 (or any other Section) of Division 9 of the Code); provided
that upon the termination, lapsing or expiration of any such prohibition, such license or contract, as applicable, shall automatically be subject to the security interest granted in favor of Collateral Agent hereunder and become part of the
“Collateral.” 
 Pursuant to the terms of a certain negative pledge arrangement with Collateral Agent and the
Lenders, Borrower has agreed not to encumber any of its Intellectual Property.

	 DEBTOR:

	 SECURED PARTY:
	  	 OXFORD FINANCE LLC,
	  		  	
		  	 as Collateral Agent
	  		  	

 EXHIBIT A TO UCC FINANCING STATEMENT 

Description of Collateral 

The Collateral consists of all of Debtor’s right, title and interest in and to the following personal property: 

All goods, Accounts (including health-care receivables), Equipment, Inventory,
contract rights or rights to payment of money, leases, license agreements, franchise agreements, General Intangibles (except as noted below), commercial tort claims, documents, instruments (including any promissory notes), chattel paper (whether
tangible or electronic), cash, deposit accounts and other Collateral Accounts, all certificates of deposit, fixtures, letters of credit rights (whether or not the letter of credit is evidenced by a writing), securities, and all other investment
property, supporting obligations, and financial assets, whether now owned or hereafter acquired, wherever located; and 

All Borrower’s Books relating to the foregoing, and any and all claims, rights and interests in any of the above and all
substitutions for, additions, attachments, accessories, accessions and improvements to and replacements, products, proceeds and insurance proceeds of any or all of the foregoing. 

Notwithstanding the foregoing, the Collateral does not include (i) any Intellectual Property; provided, however, the
Collateral shall include all Accounts and all proceeds of Intellectual Property. If a judicial authority (including a U.S. Bankruptcy Court) would hold that a security interest in the underlying Intellectual Property is necessary to have a security
interest in such Accounts and such property that are proceeds of Intellectual Property, then the Collateral shall automatically, and effective as of the Effective Date, include the Intellectual Property to the extent necessary to permit perfection
of Collateral Agent’s security interest in such Accounts and such other property of Borrower that are proceeds of the Intellectual Property; (ii) more than 65% of the total combined voting power of all classes of stock entitled to vote the
shares of capital stock (the “Shares”) of any Foreign Subsidiary, if Borrower demonstrates to Collateral Agent’s reasonable satisfaction that a pledge of more than sixty five percent (65%) of the Shares of such Subsidiary creates a
present and existing adverse tax consequence to Borrower under the U.S. Internal Revenue Code; and (iii) any license or contract, in each case if the granting of a Lien in such license or contract is prohibited by or would constitute a default
under the agreement governing such license or contract (but (A) only to the extent such prohibition is enforceable under applicable law and (B) other than to the extent that any such term would be rendered ineffective pursuant to Sections 9-406, 9-408 or 9-409 (or any other Section) of Division 9 of the Code); provided that upon the termination, lapsing or expiration of
any such prohibition, such license or contract, as applicable, shall automatically be subject to the security interest granted in favor of Collateral Agent hereunder and become part of the “Collateral.” 

Pursuant to the terms of a certain negative pledge arrangement with Collateral Agent and the Lenders, Debtor has agreed not to
encumber any of its Intellectual Property. 
 Capitalized terms used but not defined herein have the meanings ascribed in
the Uniform Commercial Code in effect in the State of California as in effect from time to time (the “Code”) or, if not defined in the Code, then in the Loan and Security Agreement by and between Debtor, Secured Party and the other Lenders
party thereto (as modified, amended and/or restated from time to time).

	 	3.	 Section 2.2(b) of the Loan Agreement is hereby amended and restated in its entirety as follows:















 (b) Repayment. Borrower shall make monthly payments of interest only commencing on the first
(1st) Payment Date following the Funding Date of each Term Loan, and continuing on the Payment Date of each successive month thereafter through and including the Payment Date immediately preceding the Amortization Date. Borrower agrees to pay, on
the Funding Date of each Term Loan, any initial partial monthly interest payment otherwise due for the period between the Funding Date of such Term Loan and the first Payment Date thereof. Commencing on the Amortization Date, and continuing on the
Payment Date of each month thereafter, Borrower shall make consecutive equal monthly payments of principal, together with applicable interest, in arrears, to each Lender, as calculated by Collateral Agent (which calculations shall be deemed correct
absent manifest error) based upon: (1) the amount of such Lender’s Term Loan, (2) the effective rate of interest, as determined in Section 2.3(a), and (3) a repayment schedule equal to
(i) thirty-six (36) months, if the Positive Data Event does not occur and (ii) thirty (30) months, if the Positive Data Event occurs. All unpaid principal and accrued and unpaid interest with

Borrower irrevocably authorizes each Lender to make or cause to be made, on or about
the Funding Date of any Term Loan or at the time of receipt of any payment of principal on such Lender’s Secured Promissory Note, an appropriate notation on such Lender’s Secured Promissory Note Record reflecting the making of such Term
Loan or (as the case may be) the receipt of such payment. The outstanding amount of each Term Loan set forth on such Lender’s Secured Promissory Note Record shall be prima facie evidence of the principal amount thereof owing and unpaid to such
Lender, but the failure to record, or any error in so recording, any such amount on such Lender’s Secured Promissory Note Record shall not limit or otherwise affect the obligations of Borrower under any Secured Promissory Note or any other Loan
Document to make payments of principal of or interest on any Secured Promissory Note when due. Upon receipt of an affidavit of an officer of a Lender as to the loss, theft, destruction, or mutilation of its Secured Promissory Note, Borrower shall
issue, in lieu thereof, a replacement Secured Promissory Note in the same principal amount thereof and of like tenor.
