 The parties agree as follows:

  

	1.	DEFINITIONS AND CONSTRUCTION. 

 1.1 Definitions. As used in this

	2.	LOAN AND TERMS OF PAYMENT. 

 2.1 Credit Extensions. 

(a) Promise to Pay. Borrower promises to pay to Bank, in lawful money of the United States of America, the aggregate unpaid
principal amount of all Credit Extensions made by Bank to Borrower, together with interest on the unpaid principal amount of such Credit Extensions at rates in accordance with the terms hereof. 

(b) Term Loans. Subject to and upon the terms and conditions of this Agreement, Bank agrees to make one or more term loans
to Borrower in an aggregate principal amount not to exceed $20,000,000 in two tranches, “Tranche A” and “Tranche B,” as follows: 

(i) Tranche A. On the Closing Date, or as soon thereafter as all conditions precedent to the making thereof have been met,
Bank shall make one term loan to Borrower in an aggregate principal amount equal to $5,000,000 (the “Initial Tranche A Term Loan”). Thereafter, during the Tranche A Draw Period, Borrower may request and Bank agrees to make one or more
additional term loans in an aggregate principal amount not to exceed $5,000,000 (each a “Tranche A Term Loan” and together with the “Initial Tranche A Term Loan,” the “Tranche A Term Loans”).

(ii) Tranche B. During the Tranche B Draw Period, Borrower may request and Bank agrees to make one or more term loans to
Borrower in an aggregate principal amount not to exceed $10,000,000 (each a “Tranche B Term Loan” and collectively, the “Tranche B Term Loans” and together with the “Tranche A Term Loans,” each a “Term Loan”
and collectively, the “Term Loans”). The proceeds of the Term Loans shall be used for general working capital purposes and for capital expenditures. 

(iii) Repayment. Interest shall accrue from the date of each Term Loan at the rate specified in Section 2.3(a), and prior
to the Availability End Date shall be payable monthly beginning on the 3rd day of the month next following the date such Term Loan is funded, and continuing on the same day of each month thereafter. Any Term Loans that are outstanding on the
Availability End Date shall be payable in equal monthly 

  
 1 

 
installments of principal, plus all accrued interest, beginning on the Amortization Start Date and continuing on the same day of each month thereafter through the Term Loan Maturity Date, at
which time all amounts due in connection with the Term Loans and any other amounts due under this Agreement shall be immediately due and payable. Term Loans, once repaid, may not be reborrowed.

(iv) Prepayment. Borrower may prepay all or any portion of the Term Loans at any time, provided that Borrower may not
reborrow any amount so prepaid, and provided further that upon any prepayment, including any prepayment required because of the occurrence of an Event of Default, Borrower shall pay, in addition to all outstanding principal and accrued interest on
the Term Loans, the Prepayment Fee (if applicable). 
 (v) Borrowing Notice. When Borrower desires to obtain a Term
Loan, Borrower shall notify Bank (which notice shall be irrevocable) by facsimile transmission to be received no later than 3:30 p.m. Eastern time on the Business Day prior to the date on which the Term Loan is to be made. Such notice shall be
substantially in the form of Exhibit C. The notice shall be signed by an Authorized Officer. 
 2.2 Intentionally
Omitted. 
 2.3 Interest Rates, Payments, and Calculations. 

(a) Interest Rate for Term Loans. Except as set forth in Section 2.3(b), the Term Loans shall bear interest, on the
outstanding daily balance thereof, at a variable annual rate equal to the greater of (A) 1.00% above the Prime Rate then in effect or (B) 4.50%. 

(b) Late Fee; Default Rate. If any payment is not made within 15 days after the date such payment is due, Borrower shall
pay Bank a late fee equal to the lesser of (i) 5% of the amount of such unpaid amount or (ii) the maximum amount permitted to be charged under applicable law. All Obligations shall bear interest, from and after the occurrence and during the
continuance of an Event of Default, at a rate equal to 5 percentage points above the interest rate applicable immediately prior to the occurrence of the Event of Default. 

(c) Payments. Interest on the Term Loans shall be due and payable on the 3rd calendar day of each month during the term
hereof. Bank shall, at its option, charge such interest, all Bank Expenses, and all Periodic Payments against any of Borrower’s deposit accounts. Any interest not paid when due shall be compounded by becoming a part of the
Obligations, and such interest shall thereafter accrue interest at the rate then applicable hereunder. 
 (d)
Computation. In the event the Prime Rate is changed from time to time hereafter, the applicable rate of interest hereunder shall be increased or decreased, effective as of the day the Prime Rate is changed, by an amount equal to such
change in the Prime Rate. All interest chargeable under the Loan Documents shall be computed on the basis of a 360 day year for the actual number of days elapsed. 

2.4 Crediting Payments. Unless an Event of Default has occurred and is continuing, Bank shall credit a wire transfer of
funds, check or other item of payment to such deposit account or Obligation as Borrower specifies. After the occurrence and during the continuance of an Event of Default, Bank shall have the right, in its sole discretion, to immediately apply
any wire transfer of funds, check, or other item of payment Bank may receive to conditionally reduce Obligations, but such applications of funds shall not be considered a payment on account unless such payment is of immediately available federal
funds or unless and until such check or other item of payment is honored when presented for payment. Notwithstanding anything to the contrary contained herein, any wire transfer or payment received by Bank after 5:30 p.m. Eastern time shall be
deemed to have been received by Bank as of the opening of business on the immediately following Business Day. Whenever any payment to Bank under the Loan Documents would otherwise be due (except by reason of acceleration) on a date that is not
a Business Day, such payment shall instead be due on the next Business Day, and additional fees or interest, as the case may be, shall accrue and be payable for the period of such extension. 

  
 2 

 2.5 Fees. Borrower shall pay to Bank the following: 

(a) Prepayment Fee. The Prepayment Fee with respect to each Term Loan, if and when applicable. 

(b) Bank Expenses. On the Closing Date, all Bank Expenses incurred through the Closing Date, and, after the Closing Date,
all Bank Expenses, as and when they become due. Bank acknowledges receipt of a good faith deposit from Borrower in the amount of $25,000, which good faith deposit shall be applied to Bank Expenses accrued through the Closing Date on the Closing
Date, with any remainder to be credited to Borrower’s deposit account at Bank.
 2.6 Term. This Agreement shall
become effective on the Closing Date and, subject to Section 12.7, shall continue in full force and effect for so long as any Obligations (other than inchoate indemnity obligations) remain outstanding or Bank has any obligation to make Credit
Extensions under this Agreement. Notwithstanding the foregoing, Bank shall have the right to terminate its obligation to make Credit Extensions under this Agreement immediately and without notice upon the occurrence and during the continuance
of an Event of Default.

 3 

 3.2 Conditions Precedent to all Credit Extensions. The obligation of Bank to
make each Credit Extension, including the initial Credit Extension, is contingent upon the Borrower’s compliance with Section 3.1 above, and is further subject to the following conditions: 

(a) timely receipt by Bank of the Loan Advance/Paydown Request Form as provided in Section 2.1;

Extension (provided, however, that those representations and warranties expressly referring to another date shall be true, correct and complete in all material respects as of such date). The making of each Credit Extension shall be deemed to be
a representation and warranty by Borrower on the date of such Credit Extension as to the accuracy of the facts referred to in this Section 3.2. 

3.3 Post-Closing Condition. Borrower shall use its best efforts to deliver to Bank a landlord’s waiver for

	4.	CREATION OF SECURITY INTEREST. 

 4.1 Grant of Security
Interest. Borrower grants and pledges to Bank a continuing security interest in the Collateral to secure prompt repayment of any and all Obligations (other than inchoate indemnity obligations) and to secure prompt performance by Borrower of
each of its covenants and duties under the Loan Documents. Except for Permitted Liens or as disclosed in the Schedule, such security interest constitutes a valid, first priority security interest in the presently existing Collateral, and will
constitute a valid, first priority security interest in later-acquired Collateral. Borrower also hereby agrees not to sell, transfer, assign, mortgage, pledge, lease, grant a security interest in, or encumber any of its Intellectual Property,
other than Permitted Liens and Permitted Transfers. Notwithstanding any termination of this Agreement or of any filings undertaken related to Bank’s rights under the Code, Bank’s Lien on the Collateral shall remain in effect for so long as
any Obligations (other than inchoate indemnity obligations) are outstanding. If this Agreement is terminated, all Obligations are satisfied in full in cash and Bank has no further obligations to make any Credit Extensions under this Agreement,
Bank shall terminate its Lien in the Collateral and all rights therein shall revert to Borrower, and Bank shall, at Borrower’s sole cost and expense, deliver any documents and agreements necessary to evidence the termination of its security
interests in the Collateral. 
 4.2 Perfection of Security Interest. Borrower authorizes Bank to file at any time
financing statements, continuation statements, and amendments thereto that (i) either specifically describe the Collateral or describe the Collateral as all assets of Borrower of the kind pledged hereunder, but excluding, for the avoidance of doubt,
Intellectual Property, and (ii) contain any other information required by the Code for the sufficiency of filing office acceptance of any financing statement, continuation statement, or amendment, including whether Borrower is an organization, the
type of organization and any organizational identification number issued to Borrower, if applicable. Borrower shall have possession of the Collateral, except where expressly otherwise provided in this Agreement or where Bank chooses to perfect
its security interest by possession in addition to the filing of a financing statement. Where Collateral is in possession of a third party bailee, Borrower shall take such steps as Bank reasonably requests for Bank to (i) subject to
Section 7.11 below, obtain an acknowledgment, in form and substance reasonably satisfactory to Bank, of the bailee that the bailee holds such Collateral for the benefit of Bank, and (ii) obtain “control” of any Collateral consisting
of investment property, deposit accounts, letter-of-credit rights 

  
 4 

 
or electronic chattel paper (as such items and the term “control” are defined in Revised Article 9 of the Code) by causing the securities intermediary or depositary institution or
issuing bank to execute a control agreement in form and substance reasonably satisfactory to Bank. Borrower will not create any chattel paper without placing a legend on the chattel paper acceptable to Bank indicating that Bank has a security
interest in the chattel paper. Borrower from time to time may deposit with Bank specific cash collateral to secure specific Obligations; Borrower authorizes Bank to hold such specific balances in pledge and to decline to honor any drafts
thereon or any request by Borrower or any other Person to pay or otherwise transfer any part of such balances for so long as the specific Obligations are outstanding (other than inchoate indemnity obligations). Borrower shall take such other
actions as Bank requests to perfect its security interests granted under this Agreement. 
  

	5.	REPRESENTATIONS AND WARRANTIES. 

 Borrower represents and warrants as follows: 

5.1 Due Organization and Qualification. Borrower and each Subsidiary is duly existing under the laws of the state in which
it is organized and qualified and licensed to do business in any state in which the conduct of its business or its ownership of property requires that it be so qualified, except where the failure to do so would not reasonably be expected to cause a
Material Adverse Effect. 
 5.2 Due Authorization; No Conflict. The execution, delivery, and performance of the Loan
Documents are within Borrower’s powers, have been duly authorized, and are not in conflict with nor constitute a breach of any provision contained in Borrower’s Certificate of Incorporation or Bylaws, nor will they constitute an event of
default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement by which it is bound, except to the extent such default would not reasonably be expected to cause a Material Adverse Effect. 

5.3 Collateral. Borrower has rights in or the power to transfer the Collateral, and its title to the Collateral is free and
clear of Liens, adverse claims, and restrictions on transfer or pledge except for Permitted Liens. Other than movable items of personal property such as laptop computers and products and supplies used in the clinical trials, work in process,
manufacturing facilities, or at vendor facilities in the ordinary course of Borrower’s business, all Collateral having an aggregate book value in excess of $100,000 is located solely in the Collateral States. All Inventory is in all
material respects of good and merchantable quality, free from all material defects, except for Inventory for which adequate reserves have been made. Except as set forth in the Schedule, and subject to the terms of Section 6.6, none of the
Borrower’s Cash is maintained or invested with a Person other than Bank or Bank’s affiliates. 
 5.4 Intellectual
Property Collateral. Borrower is the sole owner of the intellectual property created or purchased by Borrower, except for licenses granted by Borrower to its customers in the ordinary course of business. To the best of Borrower’s
knowledge, each of the copyrights, trademarks and patents created or purchased by Borrower is valid and enforceable, and no part of the intellectual property created or purchased by Borrower has been judged invalid or unenforceable, in whole or in
part, and no claim has been made to Borrower that any part of the intellectual property created or purchased by Borrower violates the rights of any third party except to the extent such claim would not reasonably be expected to cause a Material
Adverse Effect. 
 5.5 Name; Location of Chief Executive Office. Except as disclosed in the Schedule, Borrower has not
done business under any name other than that specified on the signature page hereof, and its exact legal name is as set forth in the first paragraph of this Agreement. The chief executive office of Borrower is located at the address indicated
in Section 10 hereof except for changes for which notice has been given to Bank in compliance with Section 7.2. 
 5.6
Litigation. Except as set forth in the Schedule, there are no actions or proceedings pending by or against Borrower or any Subsidiary before any court or administrative agency in which a likely adverse decision would reasonably be
expected to have a Material Adverse Effect. 

  
 5 

 5.7 No Material Adverse Change in Financial Statements. All consolidated and
consolidating financial statements related to Borrower and any Subsidiary that are delivered by Borrower to Bank fairly present in all material respects Borrower’s consolidated and consolidating financial condition as of the date thereof and
Borrower’s consolidated and consolidating results of operations for the period then ended, except in the case of unaudited financial statements for (a) the omission of footnotes, (b) accounting adjustments relating to stock compensation,
equity, partnership and collaboration agreements and (c) normal year-end adjustments. There has not been a material adverse change in the consolidated or in the consolidating financial condition of Borrower since the date of the most recent of such
financial statements submitted to Bank. 
 5.8 Solvency, Payment of Debts. Borrower is able to pay its debts (including
trade debts) as they mature; the fair saleable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; and Borrower is not left with unreasonably small capital after the transactions
contemplated by this Agreement. 
 5.9 Compliance with Laws and Regulations. Borrower and each Subsidiary have met the
minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. No event has occurred resulting from Borrower’s failure to comply with ERISA that is reasonably likely to result in Borrower’s
incurring any liability that could reasonably be expected to have a Material Adverse Effect. Borrower is not an “investment company” or a company “controlled” by an “investment company” within the meaning of the
Investment Company Act of 1940. Borrower is not engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulations T and U of
the Board of Governors of the Federal Reserve System). Borrower has not violated any statutes, laws, ordinances or rules applicable to it, the violation of which would reasonably be expected to have a Material Adverse Effect. Borrower and
each Subsidiary have filed or caused to be filed all tax returns required to be filed (or filed extensions therefor), and have paid, or have made adequate provision for the payment of, all taxes reflected therein except those being contested in good
faith with adequate reserves under GAAP or where the failure to file such returns or pay such taxes would not reasonably be expected to have a Material Adverse Effect. 

5.10 Subsidiaries. Borrower does not own any stock, partnership interest or other equity securities of any Person, except
for Permitted Investments. 
 5.11 Government Consents. Borrower and each Subsidiary have obtained all consents,
approvals and authorizations of, made all declarations or filings with, and given all notices to, all governmental authorities that are necessary for the continued operation of Borrower’s business as currently conducted, except where the
failure to do so would not reasonably be expected to cause a Material Adverse Effect. 
 5.12 Inbound Licenses. Except as
disclosed on the Schedule, Borrower is not a party to, nor is bound by, any material license or other agreement important for the conduct of Borrower’s business that prohibits or otherwise restricts Borrower from granting a security interest in
Borrower’s interest in such license or agreement or any other property important for the conduct of Borrower’s business, other than this Agreement or the other Loan Documents. 

5.13 Full Disclosure. No representation, warranty or other statement made by Borrower in any certificate or written
statement furnished to Bank taken together with all such certificates and written statements furnished to Bank contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained in
such certificates or statements not misleading in light of the circumstances in which they were made, it being recognized by Bank that the projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are not to
be viewed as facts and that actual results during the period or periods covered by any such projections and forecasts may differ from the projected or forecasted results.

	6.	AFFIRMATIVE COVENANTS. 

 Borrower covenants that, until payment in full of all
outstanding Obligations (other than inchoate indemnity obligations), and for so long as Bank may have any commitment to make a Credit Extension hereunder, Borrower shall do all of the following: 

6.1 Good Standing and Government Compliance. Borrower shall maintain its and each of its Subsidiaries’ corporate
existence and good standing in their respective states of formation, shall maintain qualification and good standing in each other jurisdiction in which the failure to so qualify would reasonably be expected to have a Material Adverse Effect, and
shall furnish to Bank the organizational identification number issued to Borrower by the authorities of the state in which Borrower is organized, if applicable. Borrower shall meet, and shall cause each Subsidiary to meet, the minimum funding
requirements of ERISA with respect to any employee benefit plans subject to ERISA. Borrower shall comply, and shall cause each Subsidiary to comply, with all statutes, laws, ordinances and government rules and regulations to which it is
subject, and shall maintain, and shall cause each of its Subsidiaries to maintain, in force all licenses, approvals and agreements, the loss of which or failure to comply with which would reasonably be expected to have a Material Adverse Effect.

 6.2 Financial Statements, Reports, Certificates. Borrower shall deliver to Bank: (i) as soon as available, but in
any event within 30 days after the end of each calendar month, a company prepared consolidated and consolidating balance sheet, income statement, covering Borrower’s operations during such period, in a form reasonably acceptable to Bank and
certified by a Responsible Officer; (ii) as soon as available, but in any event within 270 days after the end of Borrower’s fiscal year, audited consolidated and consolidating financial statements of Borrower prepared in accordance with GAAP,

statements of an independent certified public accounting firm reasonably acceptable to Bank; (iii) annual budget approved by Borrower’s Board of Directors as soon as available but not later than February 28th of each year during the term of this Agreement; (iv) copies of all statements, reports and notices sent or made available generally by Borrower to its security holders or to any holders of

(a) Within 30 days after the last day of each month, Borrower shall deliver to Bank with the monthly financial statements a Compliance
Certificate certified as of the last day of the applicable month and signed by a Responsible Officer in substantially the form of Exhibit D hereto. 

(b) As soon as possible and in any event within 3 Business Days after becoming aware of the occurrence or existence of an Event of
Default hereunder, Borrower shall deliver to Bank a written statement of a Responsible Officer setting forth details of the Event of Default, and the action which Borrower has taken or proposes to take with respect thereto. 

(c) Bank (through any of its officers, employees, or agents) shall have the right, upon reasonable prior notice, from time to time
during Borrower’s usual business hours but no more than once every twelve (12) months (unless an Event of Default has occurred and is continuing), to inspect Borrower’s Books and to make copies thereof and to check, test, inspect, audit
and appraise the Collateral at Borrower’s expense in order to verify Borrower’s financial condition or the amount, condition of, or any other matter relating to, the Collateral. 

Borrower may deliver to Bank on an electronic basis any certificates, reports or information required pursuant to this Section 6.2, and
Bank shall be entitled to rely on the information contained in the electronic files, provided that Bank in good faith believes that the files were delivered by a Responsible Officer. Borrower shall include a submission date on any certificates
and reports to be delivered electronically. 
 Notwithstanding the foregoing, documents required to be delivered pursuant to the terms
hereof (to the extent any such documents are included in materials otherwise filed with the SEC) may be delivered electronically and if so delivered, shall be deemed to have been delivered on the date on which Borrower posts such documents, or
provides a link thereto, on Borrower’s website on the internet at Borrower’s website address.

 6.3 Inventory and Equipment; Returns. Borrower shall keep all Inventory and
Equipment in good and merchantable condition, free from all material defects except for Inventory and Equipment (i) sold in the ordinary course of business, and (ii) for which adequate reserves have been made, in all cases in the United States and
such other locations as to which Borrower gives prior written notice. Returns and allowances, if any, as between Borrower and its account debtors shall be on the same basis and in accordance with the usual customary practices of Borrower, as
they exist on the Closing Date. Borrower shall promptly notify Bank of all returns and recoveries and of all disputes and claims involving inventory having a book value of more than $100,000. 

6.4 Taxes. Borrower shall make, and cause each Subsidiary to make (or file extensions for), due and timely payment or
deposit of all material federal, state, and local taxes, assessments, or contributions required of it by law, including, but not limited to, those laws concerning income taxes, F.I.C.A., F.U.T.A. and state disability, and will execute and deliver to
Bank, on demand, proof satisfactory to Bank indicating that Borrower or a Subsidiary has made such payments or deposits and any appropriate certificates attesting to the payment or deposit thereof; provided that Borrower or a Subsidiary need not
make any payment if the amount or validity of such payment is contested in good faith by appropriate proceedings and is reserved against (to the extent required by GAAP) by Borrower or such Subsidiary. 

6.5 Insurance. Borrower, at its expense, shall (i) keep the Collateral insured against loss or damage, and (ii) maintain
liability and other insurance, in each case as reasonably determined by Borrower, in good faith, to be consistent with the insurance maintained by other owners in businesses similar to Borrower’s. All such policies of insurance shall be in
such form, with such companies, and in such amounts as reasonably satisfactory to Bank. All policies of property insurance shall contain a lender’s loss payable endorsement, in a form reasonably satisfactory to Bank, showing Bank as
lender’s loss payee. All liability insurance policies shall show, or have endorsements showing, Bank as an additional insured. Any such insurance policies shall specify that the insurer must give at least 20 days’ notice to Bank
before canceling its policy for any reason (provided that only ten days’ prior notice is required due to cancellation for non-payment of premium). Within 30 days of the Closing Date, Borrower shall cause to be furnished to Bank a copy of
its policies including any endorsements covering Bank or showing Bank as an additional insured. Upon Bank’s request, Borrower shall deliver to Bank certified copies of the policies of insurance and evidence of all premium
payments. Proceeds payable under any casualty policy will, at Borrower’s option, be payable to Borrower to replace the property subject to the claim, provided that any such replacement property shall be deemed Collateral in which Bank has
been granted a first priority security interest, provided that if an Event of Default has occurred and is continuing, all proceeds payable under any such policy shall, at Bank’s option, be payable to Bank to be applied on account of the
Obligations. 
 6.6 Primary Depository. As soon as possible, but in any event no later than 30 days after the Closing
Date, Borrower shall maintain its primary depository and operating accounts with Bank and all of its investment accounts with Bank or Bank’s affiliates; provided that prior to maintaining any investment accounts with Bank’s affiliates,
Borrower, Bank, and any such affiliate shall have entered into a securities account control agreement with respect to any such investment accounts, in form and substance satisfactory to Bank. Notwithstanding the above, Borrower shall be
permitted to maintain Cash in one or more accounts outside of Bank, provided that the total aggregate amount of Cash maintained in such accounts does not exceed $100,000 at any time and for the avoidance of doubt, no control agreements shall be
required for any such accounts. 
 6.7 Financial Covenants. 

(a) Milestone Covenant. Borrower shall achieve the Milestone Covenant. 

(b) Subsequent Covenant/Milestone. Borrower and Bank will mutually agree on a financial covenant and/or milestone for fiscal year 2018,
and all subsequent fiscal years, to be included as an affirmative covenant herein, which shall be based on the projections delivered by Borrower to Bank in accordance with Section 6.2(iii) hereof and memorialized in an amendment to this Agreement
that Borrower hereby agrees to execute on or prior to the date that is 30 days after Borrower’s delivery to Bank of the annual projections for the 2018 fiscal year. 

6.8 Intentionally Omitted. 

6.9 Consent of Inbound Licensors. After entering into or becoming bound by any material inbound license or agreement,
Borrower shall: (i) provide written notice to Bank of the material terms of such license or agreement with a description of its likely impact on Borrower’s business or financial condition; and (ii) in good faith use commercially reasonable
efforts to obtain the consent of, or waiver by, any person whose consent or waiver is necessary for Borrower’s interest in such licenses or contract rights to be deemed Collateral and for Bank to have a

  
 8 

 
security interest in it that might otherwise be restricted by the terms of the applicable license or agreement, whether now existing or entered into in the future, provided, however, that the
failure to obtain any such consent or waiver shall not constitute a default under this Agreement. 
 6.10 Creation/Acquisition of
Subsidiaries. In the event any Borrower or any Subsidiary of any Borrower creates or acquires any Subsidiary, Borrower or such Subsidiary shall promptly notify Bank of such creation or acquisition, and Borrower or such Subsidiary shall take
all actions reasonably requested by Bank to achieve any of the following with respect to such “New Subsidiary” (defined as a Subsidiary formed after the date hereof during the term of this Agreement): (i) to cause such New Subsidiary
to become either a co-Borrower hereunder or a secured guarantor with respect to the Obligations, if such New Subsidiary is organized under the laws of the United States; and (ii) to grant and pledge to Bank a perfected security interest in 100% of
the stock, units or other evidence of ownership held by Borrower or its Subsidiaries of any such New Subsidiary which is organized under the laws of the United States, and 65% of the stock, units or other evidence of ownership held by Borrower or
its Subsidiaries of any such New Subsidiary which is not organized under the laws of the United States. 
 6.11 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 Bank to effect the purposes of this Agreement.

Change in Control, and (iv) Borrower is the surviving entity; or (b) the Obligations are repaid in full concurrently with the closing of any merger or consolidation of Borrower in which Borrower is not the surviving entity; provided, however, that
Borrower shall not, without Bank’s prior written consent, enter into any binding contractual arrangement with any Person to attempt to facilitate a merger or acquisition of Borrower; provided, however, Borrower may enter into any such agreement
without Bank’s prior written consent so long as (i) no Event of Default exists when such agreement is entered into by Borrower, (ii) such agreement does not give such Person the right to claim any fee, payment or damages from

creditors, an asset turnover to Borrower’s creditors (including, without limitation, Bank), foreclosure, bankruptcy or similar liquidation, and (iii) Borrower notifies Bank in advance of entering into such an agreement (provided, the failure to

(i) the licensors of in-licensed property with respect to such property or (ii) the lessors of specific equipment or lenders financing specific equipment with respect to such leased or financed equipment) that Borrower in the future will refrain
from creating, incurring, assuming or allowing any Lien with respect to any of Borrower’s property. 
 7.6
Distributions. Pay any dividends or make any other distribution or payment on account of or in redemption, retirement or purchase of any capital stock, except that Borrower may (i) repurchase the stock of former employees, consultants or
directors pursuant to stock repurchase agreements in an aggregate amount not to exceed $250,000 in any fiscal year, so long as an Event of Default does not exist prior to such repurchase or would not exist after giving effect to such repurchase, and
(ii) repurchase the stock of former employees, consultants, or directors pursuant to stock repurchase agreements in any amount where the consideration for the repurchase is the cancellation of indebtedness owed by such former employees, consultants

7.9 Transactions with Affiliates. Directly or indirectly enter into or permit to exist any material transaction with any
Affiliate of Borrower except (i) for transactions that are in the ordinary course of Borrower’s business, upon fair and reasonable terms that are no less favorable to Borrower than would be obtained in an arm’s length transaction with
a non-affiliated Person, and (ii) the sale of Borrower’s equity securities in bona fide transactions with Borrower’s existing investors that do not result in a Change in Control. 

7.10 Subordinated Debt. Make any payment in respect of any Subordinated Debt, or permit any of its Subsidiaries to make any
such payment, except in compliance with the terms of such Subordinated Debt, or amend any provision affecting Bank’s rights contained in any documentation relating to the Subordinated Debt without Bank’s prior written consent, except in
compliance with the terms of the applicable Subordination Agreement.

excess of $100,000 with a bailee, warehouseman, collocation facility or similar third party unless the third party has been notified of Bank’s security interest and Bank (a) has received an acknowledgment from the third party that it is holding
or will hold the 

  
 10 

 
Inventory or Equipment for Bank’s benefit or (b) is in possession of the warehouse receipt, where negotiable, covering such Inventory or Equipment. Except for Inventory sold in the
ordinary course of business and products and supplies used in clinical trials, work in process, manufacturing facilities, or at vendor facilities in the ordinary course of Borrower’s business, and other property having an aggregate book value
not in excess of $100,000, and except for such other locations as Bank may approve in writing, Borrower shall keep the Inventory and Equipment only at the location set forth in Section 10 and such other locations of which Borrower gives Bank prior
written notice and as to which Bank is able to take such actions as may be necessary to perfect its security interest or to obtain a bailee’s acknowledgment of Bank’s rights in the Collateral. 

7.12 No Investment Company; Margin Regulation. Become or be controlled by an “investment company,” within the
meaning of the Investment Company Act of 1940, or become principally engaged in, or undertake as one of its important activities, the business of extending credit for the purpose of purchasing or carrying margin stock, or use the proceeds of any
Credit Extension for such purpose. 
 7.13 Subsidiary Assets. Permit any Subsidiary to maintain assets with a value in
excess of $50,000 at any time. 
  

	8.	EVENTS OF DEFAULT. 

 Any one or more of the following events shall constitute an
Event of Default by Borrower under this Agreement: 
 8.1 Payment Default. If Borrower fails to pay any of the
Obligations when due; 
 8.2 Covenant Default. 

(a) If Borrower fails to perform any obligation under Sections 6.2 (financial reporting), 6.4 (taxes), 6.5 (insurance), 6.6 (primary
accounts) or 6.7 (financial covenants), or violates any of the covenants contained in Article 7 of this Agreement; or 
 (b) If
Borrower fails or neglects to perform or observe any other material term, provision, condition, covenant contained in this Agreement, in any of the Loan Documents, or in any other present or future agreement between Borrower and Bank and as to any
default under such other term, provision, condition or covenant that can be cured, has failed to cure such default within 10 Business Days after Borrower receives notice thereof or any officer of Borrower becomes aware thereof; provided, however,
that if the default cannot by its nature be cured within the 10 Business Day period or cannot after diligent attempts by Borrower be cured within such 10 Business Day period, and such default is likely to be cured within a reasonable time, then
Borrower shall have an additional reasonable period (which shall not in any case exceed 30 days) to attempt to cure such default, and within such reasonable time period the failure to have cured such default shall not be deemed an Event of Default
but no Credit Extensions will be made; 
 8.3 Material Adverse Change. If there occurs any circumstance or any
circumstances which would reasonably be expected to have a Material Adverse Effect; 
 8.4 Attachment. If any material
portion of Borrower’s assets is attached, seized, subjected to a writ or distress warrant, or is levied upon, or comes into the possession of any trustee, receiver or person acting in a similar capacity and such attachment, seizure, writ or
distress warrant or levy has not been removed, discharged or rescinded within 10 days, or if Borrower is enjoined, restrained, or in any way prevented by court order from continuing to conduct all or any material part of its business affairs, or if
a judgment or other claim becomes a lien or encumbrance upon any material portion of Borrower’s assets, or if a notice of lien, levy, or assessment is filed of record with respect to any material portion of Borrower’s assets by the United
States Government, or any department, agency, or instrumentality thereof, or by any state, county, municipal, or governmental agency, and the same is not paid within ten days after Borrower receives notice thereof, provided that none of the
foregoing shall constitute an Event of Default where such action or event is stayed or an adequate bond has been posted pending a good faith contest by Borrower (provided that no Credit Extensions will be made during such cure period); 

  
 11 

 8.5 Insolvency. If Borrower becomes insolvent, or if an Insolvency Proceeding is
commenced by Borrower, or if an Insolvency Proceeding is commenced against Borrower and is not dismissed or stayed within 45 days (provided that no Credit Extensions will be made prior to the dismissal of such Insolvency Proceeding); 

8.6 Other Agreements. If there is a default or other failure to perform in any agreement to which Borrower is a party with a
third party or parties (a) 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 $250,000, (b) in connection with any lease of real property that is
material to the conduct of Borrower’s business, if such default or failure to perform results in the right of another party to terminate such lease, or (c) that would reasonably be expected to have a Material Adverse Effect; 

8.7 Judgments. If a final, uninsured judgment or judgments for the payment of money in an amount, individually or in the
aggregate, of at least $1,000,000 shall be rendered against Borrower and shall remain unsatisfied and unstayed for a period of 15 days (provided that no Credit Extensions will be made prior to the satisfaction or stay of the judgment); or 

8.8 Misrepresentations. If any material misrepresentation or material misstatement exists now or hereafter as of the date made
or deemed made in any warranty or representation set forth herein or in any certificate delivered to Bank by any Responsible Officer pursuant to this Agreement or to induce Bank to enter into this Agreement or any other Loan Document. 

 

	9.	BANK’S RIGHTS AND REMEDIES. 

 9.1 Rights and Remedies. Upon the
occurrence and during the continuance of an Event of Default, Bank may, at its election, without notice of its election and without demand, do any one or more of the following, all of which are authorized by Borrower: 

(a) Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in Section 8.5 (insolvency), all Obligations shall become immediately due and payable without any action by Bank); 

(b) Demand that Borrower (i) deposit cash with Bank in an amount equal to the amount of any Letters of Credit remaining undrawn,
as collateral security for the repayment of any future drawings under such Letters of Credit, and (ii) pay in advance all Letter of Credit fees scheduled to be paid or payable over the remaining term of the Letters of Credit, and Borrower shall
promptly deposit and pay such amounts; 
 (c) Cease advancing money or extending credit to or for the benefit of Borrower under this
Agreement or under any other agreement between Borrower and Bank; 
 (d) Settle or adjust disputes and claims directly with account
debtors for amounts, upon terms and in whatever order that Bank reasonably considers advisable; 
 (e) Make such payments and do such
acts as Bank considers necessary or reasonable to protect its security interest in the Collateral. Borrower agrees to assemble the Collateral if Bank so requires, and to make the Collateral available to Bank as Bank may designate. Borrower
authorizes Bank to enter the premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any encumbrance, charge, or lien which in Bank’s
determination appears 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 Bank a license to enter into possession of
such premises and to occupy the same, without charge, in order to exercise any of Bank’s rights or remedies provided herein, at law, in equity, or otherwise; 

  
 12 

 (f) place a “hold” on any account maintained with Bank 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; 

(g) Set off and apply to the Obligations any and all (i) balances and deposits of Borrower held by Bank, and (ii) indebtedness at any
time owing to or for the credit or the account of Borrower held by Bank; 
 (h) Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Collateral. Bank is hereby granted a license or other right, solely pursuant to the provisions of this Section 9.1, to use, without charge,
Borrower’s labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any property of a similar nature, as it pertains to the Collateral, in completing production
of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section 9.1, Borrower’s rights under all licenses and all franchise agreements shall inure to Bank’s benefit;

 (i) 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 Bank determines is commercially reasonable, and apply any proceeds to the Obligations in whatever manner or order Bank deems appropriate. Bank may sell the
Collateral without giving any warranties as to the Collateral. Bank may specifically disclaim any warranties of title or the like. This procedure will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral.
If Bank sells any of the Collateral upon credit, Borrower will be credited only with payments actually made by the purchaser, received by Bank, and applied to the indebtedness of the purchaser. If the purchaser fails to pay for the Collateral, Bank
may resell the Collateral and Borrower shall be credited with the proceeds of the sale; 
 (j) Bank may credit bid and purchase at
any public sale; 
 (k) Apply for the appointment of a receiver, trustee, liquidator or conservator of the Collateral, without notice
and without regard to the adequacy of the security for the Obligations and without regard to the solvency of Borrower, any guarantor or any other Person liable for any of the Obligations; and 

(l) Any deficiency that exists after disposition of the Collateral as provided above will be paid immediately by Borrower. 

Bank may comply with any applicable state or federal law requirements in connection with a disposition of the Collateral and compliance will not be considered
adversely to affect the commercial reasonableness of any sale of the Collateral. 
 9.2 Power of Attorney. Effective only upon
the occurrence and during the continuance of an Event of Default, Borrower hereby irrevocably appoints Bank (and any of Bank’s designated officers, or employees) as Borrower’s true and lawful attorney to: (a) send requests for verification
of Accounts or notify account debtors of Bank’s security interest in the Accounts; (b) endorse Borrower’s name on any checks or other forms of payment or security that may come into Bank’s possession; (c) sign Borrower’s name on
any invoice or bill of lading relating to any Account, drafts against account debtors, schedules and assignments of Accounts, verifications of Accounts, and notices to account debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all
claims under and decisions with respect to Borrower’s policies of insurance; (f) settle and adjust disputes and claims respecting the accounts directly with account debtors, for amounts and upon terms which Bank determines to be reasonable; and
(g) file, in its sole discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral; provided Bank may exercise such power of attorney to sign the name of Borrower on any of the documents
described in clause (g) above, regardless of whether an Event of Default has occurred. The appointment of Bank as Borrower’s attorney in fact, and each and every one of Bank’s rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid (other than inchoate indemnity obligations) and performed and Bank’s obligation to provide Credit Extensions hereunder is terminated. 

  
 13 

 9.3 Accounts Collection. At any time after the occurrence and during the
continuation of an Event of Default, Bank may notify any Person owing funds to Borrower of Bank’s security interest in such funds and verify the amount of such Account. At any time after the occurrence and during the continuance of an Event of
Default, Borrower shall collect all amounts owing to Borrower for Bank, receive in trust all payments as Bank’s trustee, and immediately deliver such payments to Bank in their original form as received from the account debtor, with proper
endorsements for deposit. 
 9.4 Bank 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 Bank may do any or all of the following after reasonable notice to Borrower: (a) make payment of the same or any part thereof; or (b) obtain and maintain insurance
policies of the type discussed in Section 6.5 of this Agreement, and take any action with respect to such policies as Bank deems prudent. Any amounts so paid or deposited by Bank shall constitute Bank Expenses, shall be immediately due and payable,
and shall bear interest at the then applicable rate hereinabove provided, and shall be secured by the Collateral. Any payments made by Bank shall not constitute an agreement by Bank to make similar payments in the future or a waiver by Bank of any
Event of Default under this Agreement. 
 9.5 Bank’s Liability for Collateral. Bank has no obligation to clean up or
otherwise prepare the Collateral for sale. All risk of loss, damage or destruction of the Collateral shall be borne by Borrower, other than any loss, damage or destruction caused by Bank’s gross negligence or willful misconduct. 

9.6 No Obligation to Pursue Others. Bank has no obligation to attempt to satisfy the Obligations by collecting them from
any other person liable for them and Bank may release, modify or waive any collateral provided by any other Person to secure any of the Obligations, all without affecting Bank’s rights against Borrower. Borrower waives any right it may have to
require Bank to pursue any other Person for any of the Obligations. 
 9.7 Remedies Cumulative. Bank’s rights and
remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative. Bank shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Bank of one
right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on Borrower’s part shall be deemed a continuing waiver. No delay by Bank shall constitute a waiver, election, or acquiescence by it. No waiver by Bank
shall be effective unless made in a written document signed on behalf of Bank and then shall be effective only in the specific instance and for the specific purpose for which it was given. Borrower expressly agrees that this Section 9.7 may not be
waived or modified by Bank by course of performance, conduct, estoppel or otherwise. 
 9.8 Demand; Protest. Except as
otherwise provided in this Agreement, Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment and any other notices relating to the Obligations. 

 

	10.	NOTICES.

	11.	CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER. 

 This Agreement shall be governed by, and construed in
accordance with, the internal laws of the State of North Carolina, without regard to principles of conflicts of law. Jurisdiction shall lie in the State of North Carolina. All disputes, controversies, claims, actions and similar proceedings arising
with respect to Borrower’s account or any related agreement or transaction shall be brought in the General Court of Justice of North Carolina sitting in Durham County, North Carolina or the United States District Court for the Middle District
of North Carolina, except as provided below with respect to arbitration of such matters. BANK AND BORROWER EACH ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH OF THEM, AFTER CONSULTING OR HAVING
HAD THE OPPORTUNITY TO CONSULT, WITH COUNSEL OF THEIR CHOICE, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY RELATED INSTRUMENT
OR LOAN DOCUMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTION OF ANY OF THEM. THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT
OR RELINQUISHED BY BANK OR BORROWER, EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY EACH OF THEM. If the jury waiver set forth in this Section 11 is not enforceable, then any dispute, controversy, claim, action or similar proceeding arising out of or
relating to this Agreement, the Loan Documents or any of the transactions contemplated therein shall be settled by final and binding arbitration held in Durham County, North Carolina in accordance with the then current Commercial Arbitration Rules
of the American Arbitration Association by one arbitrator appointed in accordance with those rules. The arbitrator shall apply North Carolina law to the resolution of any dispute, without reference to rules of conflicts of law or rules of statutory
arbitration. Judgment upon any award resulting from arbitration may be entered into and enforced by any state or federal court having jurisdiction thereof. Notwithstanding the foregoing, the parties may apply to any court of competent jurisdiction
for preliminary or interim equitable relief, or to compel arbitration in accordance with this Section. The costs and expenses of the arbitration, including without limitation, the arbitrator’s fees and expert witness fees, and reasonable
attorneys’ fees, incurred by the parties to the arbitration may be awarded to the prevailing party, in the discretion of the arbitrator, or may be apportioned between the parties in any manner deemed appropriate by the arbitrator. Unless and
until the arbitrator decides that one party is to pay for all (or a share) of such costs and expenses, both parties shall share equally in the payment of the arbitrator’s fees as and when billed by the arbitrator. 

 

	12.	GENERAL PROVISIONS. 

 12.1 Successors and Assigns. This Agreement
shall bind and inure to the benefit of the respective successors and permitted assigns of each of the parties and shall bind all persons who become bound as a debtor to this Agreement; provided, however, that neither this Agreement nor any rights
hereunder may be assigned by Borrower without Bank’s prior written consent, which consent may be granted or withheld in Bank’s sole discretion. Bank shall have the right without the consent of or notice to Borrower to sell, assign,
transfer, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights and benefits hereunder. 

12.2 Indemnification. Borrower shall defend, indemnify and hold harmless Bank and its officers, employees, and agents
against: (a) all obligations, demands, claims, and liabilities claimed or asserted by any other party in connection with the transactions contemplated by this Agreement; and (b) all losses or Bank Expenses in any way suffered, incurred, or paid by
Bank, its officers, employees and agents as a result of or in any way arising 

  
 15 

 
out of, following, or consequential to transactions between Bank and Borrower whether under this Agreement, or otherwise (including without limitation reasonable attorney’s fees and
expenses), (collectively, “Claims”) except for Claims caused by Bank’s gross negligence or willful misconduct. 
 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 Amendments in Writing, Integration. All amendments to or terminations of this Agreement or the other Loan Documents
must be in writing. All prior agreements, understandings, representations, warranties, and negotiations between the parties hereto with respect to the subject matter of this Agreement and the other Loan Documents, if any, are merged into this
Agreement and the Loan Documents. 
 12.6 Counterparts. This Agreement may be executed in any number of counterparts and by
different parties on separate counterparts, 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. Executed copies of the signature pages
of this Agreement sent by facsimile or transmitted electronically in Portable Document Format (“PDF”), or any similar format, shall be treated as originals, fully binding and with full legal force and effect, and the parties waive any
rights they may have to object to such treatment. 
 12.7 Survival. All covenants, representations and warranties made in this
Agreement shall continue in full force and effect so long as any Obligations remain outstanding (other than inchoate indemnity obligations) or Bank has any obligation to make any Credit Extension to Borrower. The obligations of Borrower to indemnify
Bank with respect to the expenses, damages, losses, costs and liabilities described in Section 12.2 shall survive until all applicable statute of limitations periods with respect to actions that may be brought against Bank have run. 

12.8 Confidentiality. In handling any confidential information, Bank and Borrower and all employees and agents of each such
party shall exercise the same degree of care that such party exercises with respect to its own proprietary information of the same types to maintain the confidentiality of any non-public information thereby received or received pursuant to this
Agreement except that disclosure of such information may be made (i) in the case of Bank, to the subsidiaries or Affiliates of Bank or Borrower in connection with their present or prospective business relations with Borrower, (ii) in the case of
Bank, to prospective transferees or purchasers of any interest in the Credit Extensions, provided that they have entered into a comparable confidentiality agreement in favor of Borrower and have delivered a copy to Borrower, (iii) as required by
law, regulations, rule or order, subpoena, judicial order or similar order, (iv) in the case of Bank, as may be required in connection with the examination, audit or similar investigation of Bank and (v) as Bank may reasonably determine in
connection with the enforcement of any remedies hereunder. Confidential information hereunder shall not include information that either: (a) is in the public domain or in the knowledge or possession of the receiving party when disclosed to such
party, or becomes part of the public domain after disclosure to such receiving party through no fault of such receiving party; or (b) is disclosed to such receiving party by a third party, provided the receiving party does not have actual knowledge
that such third party is prohibited from disclosing such information.

	 Expiration Date:
	  	                                 

 THIS WARRANT CERTIFIES THAT, for good and
valuable consideration, the receipt of which is hereby acknowledged, PACIFIC WESTERN BANK or its assignee or transferee (“Holder”) is entitled to purchase the number
of fully paid and nonassessable shares of common stock (the “Shares”) of the corporation (the “Company”) at the initial exercise price per Share (the “Warrant Price”) all as set forth above and as
adjusted pursuant to Article 2 of this warrant, subject to the provisions and upon the terms and conditions set forth in this warrant. Reference is made to Section 4.4 of this warrant, whereby Pacific Western Bank shall transfer this warrant to
its parent company, PacWest Bancorp.
 ARTICLE 1 

EXERCISE 
 1.1
Method of Exercise. Holder may exercise this warrant by delivering this warrant and a duly executed Notice of Exercise in substantially the form attached as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the cashless exercise right set forth in Section 1.2, Holder shall also deliver to the Company a check for the aggregate Warrant Price for the Shares being purchased. 

1.2 Cashless Exercise. In lieu of exercising this warrant as specified in Section 1.1, Holder may from time to time
exercise this warrant, in whole or in part, into a number of Shares determined by dividing (a) the aggregate fair market value of the Shares issuable upon exercise of this warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be determined pursuant to Section 1.3. 
 1.3 Fair
Market Value. The fair market value of the Shares shall be the closing price of the Shares reported on the NASDAQ Global Market for the business day immediately before Holder delivers its Notice of Exercise to the Company. If the
Shares are not regularly traded in a public market, the Board of Directors of the Company shall determine fair market value in its reasonable good faith judgment. 

1.4 Delivery of Certificate and New Warrant. Promptly after Holder exercises this warrant, the Company shall deliver to
Holder certificates for the Shares acquired and, if this warrant has not been fully exercised and has not expired, a new warrant representing the Shares not so acquired. 

 1.5 Replacement of Warrants. On receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction or mutilation of this warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation,
on surrender and cancellation of this warrant, the Company at its expense shall execute and deliver, in lieu of this warrant, a new warrant of like tenor. 

1.6 Treatment of Warrant Upon Acquisition of the Company. 

1.6.1 “Acquisition.” For the purpose of this warrant, “Acquisition” means (a) any sale, license,
or other disposition of all or substantially all of the assets (including intellectual property) of the Company, or (b) any reorganization, consolidation, merger or sale of the voting securities of the Company or any other transaction where the
holders of the Company’s securities before the transaction beneficially own less than 50% of the outstanding voting securities of the surviving entity after the transaction. 

1.6.2 Exercise Upon Acquisition. Upon the closing of any Acquisition in which the consideration to be received by the
Company’s stockholders consists of cash, marketable securities, or a combination of both cash and marketable securities, this warrant shall be deemed to have been automatically exercised pursuant to Section 1.2, and thereafter Holder shall
participate in the Acquisition on the same terms as other holders of the same class of securities of the Company. For avoidance of doubt, this Section 1.6.2 shall not apply to a reincorporation of the Company. 

1.6.3 Assumption of Warrant. Upon the closing of any Acquisition not subject to Section 1.6.2, the successor entity shall
assume the obligations of this warrant, and this warrant shall thereafter be exercisable for the same securities and/or other property as would have been paid for the Shares issuable upon exercise of the unexercised portion of this warrant as if
such Shares were outstanding on and as of the closing of such Acquisition, subject to further adjustment from time to time in accordance with the provisions of this warrant.

1.7 Number of Shares. This warrant shall be exercisable for a number of Shares equal to the quotient obtained by dividing
(i) the amount of the Term Loan (as defined in that certain Loan and Security Agreement by and between the Company and Pacific Western Bank dated as of October 3, 2016) made by Pacific Western Bank to the Company on the date hereof multiplied by 2%
by (ii) the Initial Exercise Price (as defined below).
 1.8 Initial Exercise Price. The “Initial Exercise Price”
shall be the average closing price per share of the Company’s common stock during the 30 day period preceding the Issue Date hereof as such price is listed on the NASDAQ Global Market. 

  
 2. 

 ARTICLE 2 

ADJUSTMENTS TO THE SHARES 

2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on its common stock payable in common stock,
or other securities, or subdivides the outstanding common stock into a greater amount of common stock, then upon exercise of this warrant, for each Share acquired, Holder shall receive, without cost to Holder, the total number and kind of securities
to which Holder would have been entitled had Holder owned the Shares of record as of the date the dividend or subdivision occurred. 

2.2 Reclassification, Exchange or Substitution. Upon any reclassification, exchange, substitution, or other event that
results in a change of the number and/or class of the securities issuable upon exercise of this warrant, Holder shall be entitled to receive, upon exercise of this warrant, the number and kind of securities and property that Holder would have
received for the Shares if this warrant had been exercised immediately before such reclassification, exchange, substitution, or other event. The Company or its successor shall promptly issue to Holder a new warrant for such new securities or other
property. The new warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 2 including, without limitation, adjustments to the Warrant Price and to the number of
securities or property issuable upon exercise of the new warrant. The provisions of this Section 2.2 shall similarly apply to successive reclassifications, exchanges, substitutions, or other events. 

2.3 Adjustments for Combinations, Etc. If the outstanding Shares are combined or consolidated, by reclassification or
otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased. If the outstanding Shares are combined or consolidated, by reclassification or otherwise, into a greater number of shares, the Warrant Price shall be
proportionately decreased. 
 2.4 Intentionally Omitted. 

2.5 Certificate as to Adjustments. Upon each adjustment of the Warrant Price, the Company at its expense shall promptly
compute such adjustment, and furnish Holder with a certificate of its Chief Financial Officer setting forth such adjustment and the facts upon which such adjustment is based. The Company shall, upon written request, furnish Holder a certificate
setting forth the Warrant Price in effect upon the date thereof and the series of adjustments leading to such Warrant Price. 
 2.6
Fractional Shares. No fractional Shares shall be issuable upon exercise of the warrant and the number of Shares to be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise
of this warrant, the Company shall eliminate such fractional share interest by paying Holder the amount computed by multiplying the fractional interest by the fair market value of a full Share. 

ARTICLE 3 

REPRESENTATIONS AND COVENANTS OF THE COMPANY 

3.1 Representations and Warranties. The Company hereby represents and warrants to the Holder as follows: 

(a) All Shares which may be issued upon the exercise of the purchase right represented by this warrant shall, upon issuance, be duly

 3. 

 3.2 Notice of Certain Events. The Company shall provide Holder with not less
than 10 days prior written notice of, including a description of the material facts surrounding, any of the following events: (a) declaration of any dividend or distribution upon its common stock, whether in cash, property, stock, or other
securities and whether or not a regular cash dividend; (b) offering for subscription pro rata to the holders of any class or series of its stock any additional shares of stock of any class or series or other rights; (c) effecting any
reclassification or recapitalization of common stock; or (d) the merger or consolidation with or into any other corporation, or sale, lease, license, or conveyance of all or substantially all of its assets, or liquidation, dissolution or winding

MISCELLANEOUS 
 4.1
Term: Exercise Upon Expiration. This warrant is exercisable in whole or in part, at any time and from time to time on or before the Expiration Date set forth above. If this warrant has not been exercised prior to the Expiration
Date, this warrant shall be deemed to have been automatically exercised on the Expiration Date by “cashless” exercise pursuant to Section 1.2.

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN
ACCORDANCE WITH APPLICABLE LAW.

upon exercise of this warrant may not be transferred or assigned in whole or in part without compliance with applicable federal and state securities laws by the transferor and the transferee (including, without limitation, the delivery of investment
representation letters and legal opinions reasonably satisfactory to the Company, as reasonably requested by the Company). Notwithstanding the foregoing, the Company shall not require Holder to provide an opinion of counsel if the transfer is to

detail, the selling broker represents that it has complied with Rule 144(f), and the Company is provided with a copy of Holder’s notice of proposed sale.

of Holder.
