 Southlake, TX 76092 

Dear Doug: 
 On behalf of Sabre Corporation (the
“Company”), we are pleased to extend you an offer to join the Company as Executive Vice President and Chief Financial Officer with an effective date of July 23, 2018 (the “Effective Date”). We believe your background
and abilities will be an asset to the Company and will offer a mutually beneficial opportunity for both you and the Company. 
 You will report directly to
the Chief Executive Officer of the Company. While employed by the Company, you will diligently promote the business and best interests of the Company, and you will abide in all material respects with all Company policies and directives applicable to
you. 
 Your compensation and benefit package will be as follows: 
  

	 	•	 	Base Salary: Your annual base salary will be $690,000 (“Base Salary”), less withholding for taxes and deductions, which under the Company’s current payroll practices will result in a bi-weekly payment of $26,538.46, less withholding for taxes and deductions, based on 26 pay periods in a year. Your Base Salary will be reviewed annually (typically in the first quarter) for a possible increase (but
not decrease) by the Company’s Board of Directors (the “Board”) or a committee of the Board (any revised Base Salary will then be referred to as the “Base Salary”). 

 

	 	•	 	Sign-on Bonus: You will receive a one-time “sign-on” bonus of $500,000 (“Sign-on Bonus”). This Sign-on Bonus will be paid to you within 45 days of your start date with the Company, contingent upon your signing of a bonus repayment
agreement in the form attached to this letter as Exhibit A. 

  

	 	•	 	Annual Bonus: You will be eligible to participate in the Company’s annual incentive plan, the Executive Incentive Program (or any successor program). Your annual target cash bonus under that program will be
equal to 100% (“Target Bonus”) of your Base Salary earnings for the calendar year, based on your attainment of pre-established performance goals as approved each calendar year by the Board or
a committee of the Board. The annual bonus for a particular calendar year will be paid to you no later than March of the year following the year in which that bonus was earned. Notwithstanding the foregoing, for the Company’s 2018 fiscal year,
the Target Bonus will be prorated so that the Target Bonus applies only to the period following the Effective Date. 

  

	 	•	 	Participation in the Company’s Equity Incentive Plan: You will receive an initial equity grant valued at $4,250,000 on the date specified in the Company’s Policy on Grant of Equity-Based Compensation
(which is typically the 15th of the calendar month following the Effective Date). The grant value will be provided as follows: $3,500,000 in an equal number of stock options and restricted stock
units and $750,000 in PRSUs. The grant is expected to be made under the Sabre Corporation 2016 Omnibus Incentive Compensation Plan (the “Plan”) and will be subject to the terms and conditions of the Plan and the applicable award
agreements issued in connection with the grant. While employed by the Company, you will be eligible to participate in the long-term equity incentive plan maintained by the Company. On or about March 15, 2019, you will receive an equity award
with a grant-date value of no less than $2,500,000. For future grants beginning in 2020, you will receive an equity award with a target value of $2,500,000. The amount and terms and conditions of any awards to be granted to you will be approved by
the Board, the Compensation Committee of the Board or a sub-committee of the Compensation Committee, as applicable. 

 As a senior executive, you will be subject to the Company’s Stock Ownership
Guidelines. These guidelines require senior executives to meet specified ownership levels of the Company’s stock within five (5) years of becoming a senior executive. The guidelines help to further align the interests of senior
executives with the long-term interests of our stockholders, as well as promote the Company’s commitment to sound corporate governance. Your guideline level is currently three (3) times your base salary. As noted, you will have
five years to achieve this level; however, in the interim you will be subject to certain share retention requirements until you meet this guideline level. In addition, you will be subject to the Company’s Insider Trading Policy, which, among
other things, imposes certain limitations on when you can trade in the Company’s stock and requires you to pre-clear these trades. 
  

	 	•	 	Other Benefit Plans and Programs: You will be eligible to participate in the Company’s employee benefit plans, policies and other compensation and perquisite programs, including financial planning benefits
and an annual physical program, subject to the terms, conditions and eligibility requirements of each of those benefit plans, policies or other compensation programs, including amendments or modifications. While employed by the Company, you will be
entitled to paid vacation and sick leave in accordance with the Company’s vacation, holiday and other pay for time not worked policies as in effect from time to time. You will be eligible for 15 days paid time off (PTO), two floating holidays
and eight company-scheduled holidays under the Company’s current policy. Additionally, Sabre will supplement your PTO with an additional 10 days PTO per year up until Company policy dictates an equal or greater number of days. This supplemental
PTO may not be exchanged for monetary compensation if you leave the Company or at any other time. For 2018, the amount of PTO and floating holidays will be prorated based on your hire date. These benefit plans, policies or other compensation and
perquisite programs may be discontinued or changed from time to time in the Company’s sole discretion. While employed by the company, you will be entitled to the protection of all insurance policies the Company elects to maintain generally for
the benefits of its directors and officers. 

  

	 	•	 	Termination Provisions: You will be eligible to participate in the Company’s Executive Severance Plan as a Level 2 Employee, as approved by the Compensation Committee of the Board, which will provide
you with certain severance benefits in the event of your termination of employment by the Company other than for Cause or your resignation for Good Reason (each as defined in the Executive Severance Plan, a copy of which is enclosed with this
letter) and which otherwise addresses the treatment of your termination of employment. 

 All compensation payments described in this letter
will be paid in accordance with the Company’s customary payroll practices and the requirements of applicable law. 
 The Company shall pay all
reasonable attorneys’ fees and disbursements incurred by you in connection with the negotiation of this offer letter, up to an aggregate of $10,000. 

While employed by the Company, you may not, without the prior written consent of the Company, directly or indirectly, operate, participate in the management,
operations or control of, or act as an executive, officer, consultant, agent or representative of, any type of business or service (other than as an executive of the Company or any of its subsidiaries or affiliates). It will not, however, be a
violation of the foregoing requirements for you to (i) subject to the approval of the Chief Executive Officer of the Company, serve as an officer or director or otherwise participate in educational, welfare, social, religious and civic
organizations or serve as a director of other for-profit corporations that are not Competitors (as defined in the Executive Confidentiality and Restrictive Covenants Agreement), or (ii) manage your or
your family’s personal, financial and legal affairs, so long as, in the case of clause (i) or (ii), any such activities do not interfere with the performance of your duties and responsibilities to the Company. 

By signing this offer letter, you represent and warrant to, and agree with, the Company that as of the start date specified below (i) neither the
execution and delivery of this letter nor the performance of your duties 

  
 2 

 
hereunder violates or will violate the provisions of any other written agreement to which you are a party or by which you are bound or become bound, (ii) there are no written agreements by
which you are currently bound which would prevent you from performing your duties hereunder, and (iii) other than as disclosed in writing to the Company, there are no contracts to assign inventions or other intellectual property that are now in
existence between you and any other person or entity. 
 Your offer is contingent on successful completion of the Company’s new hire paperwork,
execution of the Executive Confidentiality and Restrictive Covenants Agreement attached to this letter as Exhibit A, and the satisfactory results of employment background checks. 

This offer letter is not a contract of continuing employment. Subject to the notice provisions contained in the Company’s Executive Severance Plan, your
employment by the Company is for no fixed term, and will be “at-will,” which means that either you or the Company may terminate the employment relationship at any time for any reason or for no
reason, with or without cause, and with or without notice. The laws of the State of Texas govern the construction, interpretation and enforcement of this offer letter. 

We are delighted to make you this offer. If you agree with the terms outlined in this letter, please sign this letter and return it to me within seven
(7) days of receipt. 
 Sincerely, 
 /s/ Doug Johnson

 Doug Johnson 
 Senior Vice President and Interim Chief Human
Resources Officer

conditions of this letter.

 Exhibit A 
  

 
 Bonus Agreement 
 You
will receive your signing bonus (less applicable taxes) per the terms in your offer letter. 
 Your receipt of this bonus is contingent upon your execution
of the following Bonus Agreement (the ‘Agreement’): 
  

	 	1.	If, within one year of payout of any bonus outlined in your offer letter, not including our EIP/VCP program, you are terminated by the Company for Cause (as defined in the Sabre Corporation Executive Severance Plan) or
you terminate your employment with the Company other than for Good Reason (as defined in the Sabre Corporation Executive Severance Plan), you will reimburse Sabre for a pro-rata share of your bonus. That pro-rata share will be the full amount of your signing bonus, reduced by one twelfth (1/12) for each full month of your employment with Sabre. No reduction in the reimbursement shall be made for partial months of
employment. 

  

	 	2.	This Agreement is independent of any other agreement (if any) you have or may have with Sabre. The existence of any claim you may have against Sabre shall not serve as a defense to enforcement of this Agreement.

  

	 	3.	If any provision of this Agreement is held by any court to be invalid or unenforceable, the invalid or unenforceable provision shall be fully severable, and the Agreement shall be construed as if the invalid or
unenforceable provision never comprised part of this Agreement. Further, in lieu of the invalid or unenforceable provision, there shall be automatically added, a provision as similar in terms to such invalid or unenforceable provision as may be
possible and be legal, valid and enforceable. 

  

	 	4.	You hereby authorize Sabre to deduct from your final paycheck the bonus reimbursement due Sabre under paragraph 1 of this Agreement, and any other amounts due Sabre when your employment terminates, whatever the reason
for termination. You further agree to reimburse Sabre for all reasonable expenses it incurs, including costs and attorney fees, to collect such amounts. 

  

	 	5.	This Agreement shall be interpreted under, and governed by, the laws of the State of Texas and may be enforced in any state or federal court in Tarrant County, Texas. 

 

	 	6.	Any modifications to this Agreement must be in writing and signed by both parties. 

 This Repayment Agreement
and all of its Amendments do not constitute a contract of continuous employment or a guarantee of employment with Sabre. Employment with Sabre is at-will at all times, including the duration of this Repayment
Agreement.

 Exhibit B 
 

 
 Executive Confidentiality and Restrictive Covenants Agreement 

Executive Name: Douglas E. Barnett 

Executive Title: Executive Vice President and Chief Financial Officer 

I acknowledge and agree that in my position with the Company, it is expected that: (i) I will be materially involved in conducting or overseeing aspects
of the Company’s business activities throughout the world; (ii) I will have contact with a substantial number of the Company’s employees and the Company’s then-current and actively-sought potential customers
(“Customers”) and suppliers of inventory (“Suppliers”); and (iii) I will have access to the Company’s Trade Secrets and Confidential Information. Capitalized terms used in this Agreement and not otherwise
defined in the text shall have the meanings assigned to such terms defined in paragraph IX(E) below. 
 I further acknowledge and agree that my competition
with the Company anywhere worldwide, or my attempted solicitation of the Company’s employees or Customers or Suppliers, during my employment or within the Restricted Period following my Date of Termination, would be unfair competition and would
cause substantial damages to the Company. Consequently, in consideration of my employment with the Company, the Company’s covenants in this Agreement, the provision to me by the Company of additional Trade Secrets information and Confidential
Information, and the compensation that will be payable to me in my position with the Company, I make the following covenants: 
  

	I.	Non-solicitation of Company Customers and Suppliers. 

While I am employed by the Company and for the Restricted Period following any Date of Termination, I will not, directly or indirectly, on behalf of myself or
of anyone other than the Company, solicit or hire or attempt to solicit or hire (or assist any third party in soliciting or hiring or attempting to solicit or hire) any Customer or Supplier in connection with any business activity that then competes
with the Company. 
  

	II.	Non-solicitation of Company Employees. 

 While I am
employed by the Company and for the Restricted Period following any Date of Termination, I will not, without the prior written consent of the Board, directly or indirectly, on behalf of myself or any third party, solicit or hire or recruit or, other
than in the good faith performance of my duties, induce or encourage (or assist any third party in hiring, soliciting, recruiting, inducing or encouraging) any employees of the Company or any individuals who were employees within the six month
period immediately prior thereto to terminate or otherwise alter his or her employment with the Company. Notwithstanding the foregoing, the restrictions contained in this paragraph II shall not apply to (i) general solicitations that are
not specifically directed to employees of the Company or (ii) serving as a reference at the request of an employee. 
  

	III.	Non-competition with the Company. 

 While I am
employed by the Company and for the Restricted Period following any Date of Termination, I will not, directly or indirectly, whether as an employee, director, owner, partner, shareholder (other than the passive ownership of securities in any public
enterprise which represent no more than five percent (5%) of the voting power of all securities of such enterprise), consultant, agent, co-venturer, or independent contractor or otherwise, or through any “person” (which, for purposes of
this paragraph III, shall mean an individual, a corporation, a partnership, an association, a joint-stock company, a trust, any unincorporated organization, or a government or political subdivision thereof), perform any services for or on
behalf of, any Competitor of the Company. For purposes of this Agreement, a Competitor of the Company shall mean (i) any entity or business (x) that competes or (y) engages in a line of business that competes, in each of (x) and
(y), with the business of the Company, and (ii) any unit, division, line of business, parent, subsidiary, affiliate (as defined in Rule 144 under the Securities Act of 1933, as amended), successor or assign of Travelport, Amadeus, AMEX, Etihad
Airways, American Airlines, 

 
United Airlines, Delta Airlines, Lufthansa Group, Expedia, Priceline, TripAdvisor, Alphabet, Amazon, Facebook, Concur/SAP, Oracle, Farelogix, TravelClick, Carlson Wagonlit, BCD Travel, Hewlett
Packard Enterprises, DXC Technology, Travelsky, Hogg Robinson Group Travel, Computer Sciences Corporation, SITA, Hewlett Packard, or Jeppesen. It is understood and agreed in the event that any of such entities and their respective affiliates,
successors and assigns no longer engages in a line of business that competes with any business of the Company, such entity shall no longer be deemed a Competitor of the Company for purposes of this Agreement. 

 

	IV.	Non-disclosure of Confidential Information and Trade Secrets. 

While I am employed by the Company and thereafter, except in the good faith performance of my duties hereunder or where required by law, statute, regulation or
rule of any governmental body or agency, or pursuant to a subpoena or court order, I will not, directly or indirectly, for my own account or for the account of any other person, firm or entity, use or disclose any Confidential Information or
proprietary Trade Secrets of the Company to any third person unless such Confidential Information or Trade Secret has been previously disclosed to the public or is in the public domain (other than by reason of my breach of this paragraph IV).

  

	V.	Non-Disparagement. 

 I agree not to deliberately defame or
disparage in public comments the Company or any of its respective officers, directors, members, executives or employees. I agree to reasonably cooperate with the Company (at no expense to myself) in refuting any defamatory or disparaging remarks by
any third party made in respect of the Company or their respective directors, members, officers, executives or employees. 
  

	VI.	Enforceability of Covenants. 

 I acknowledge that the Company has a present and future expectation
of business from and with the Customers and Suppliers. I acknowledge the reasonableness of the term, geographical territory, and scope of the covenants set forth in this Agreement, and I agree that I will not, in any action, suit or other
proceeding, deny the reasonableness of, or assert the unreasonableness of, the premises, consideration or scope of the covenants set forth herein and I hereby waive any such defense. I further acknowledge that complying with the provisions contained
in this Agreement will not preclude me from engaging in a lawful profession, trade or business, or from becoming gainfully employed. I agree that each of my covenants under this Agreement are separate and distinct obligations, and the failure or
alleged failure of the Company or the Board to enforce any other provision in this Agreement will not constitute a defense to the enforceability of my covenants and obligations under this Agreement. The Company and I each agree that any breach of
any covenant under this Agreement may result in irreparable damage and injury to the other party and that the other party will be entitled to seek temporary and permanent injunctive relief in any court of competent jurisdiction without the necessity
of posting any bond, unless otherwise required by the court. 
  

	VII.	Certain Exceptions. 

 Notwithstanding anything set forth herein, nothing in this Agreement shall
(i) prohibit me from making reports of possible violations of federal law or regulation to any governmental agency or entity in accordance with the provisions of and rules promulgated under Section 21F of the Securities Exchange Act of
1934, as amended, or Section 806 of the Sarbanes-Oxley Act of 2002, or of any other whistleblower protection provisions of federal law or regulation, or (ii) require notification or prior approval by the Company of any such report;
provided that, I am not authorized to disclose communications with counsel that were made for the purpose of receiving legal advice or that contain legal advice or that are protected by the attorney work product or similar privilege. Furthermore, I
will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made (i) in confidence to a federal, state or local government official, either directly or indirectly, or to
an attorney, in each case, solely for the purpose of reporting or investigating a suspected violation of law or (ii) in a complaint or other document filed in a lawsuit or proceeding, if such filings are made under seal. Nothing

  
 7 

 
herein regarding confidentiality shall prohibit me from contacting the EEOC, SEC, or other governmental agencies to report any violations of law or my belief as to such violations and no action
shall be taken to retaliate against me because of such reports or filings. 
  

	VIII.	Post-Employment Transition and Cooperation. 

 Upon and after the termination of my employment with
the Company for any reason (except my death or, if lacking sufficient physical or mental ability, my Disability), I will execute any and all documents and take any and all actions that the Company may reasonably request to effect the transition of
my duties and responsibilities to a successor, including without limitation resigning from any positions that I hold by virtue of my employment with the Company. I will make myself reasonably available with respect to, and to cooperate in
conjunction with, any litigation or investigation involving the Company, and any administrative matters (including the execution of documents, as reasonably requested). The Company agrees to compensate me (other than with respect to the provision of
testimony) for such cooperation at an hourly rate commensurate with my base salary on the Date of Termination, to reimburse me for all reasonable expenses actually incurred in connection with cooperation pursuant to this paragraph VIII, and
to provide me with legal representation. 
  

	IX.	General Provisions. 

  

	A.	Assignment and Severability 

 I acknowledge and agree that my obligations hereunder are personal, and
that I shall have no right to assign, transfer or delegate and shall not assign, transfer or delegate or purport to assign, transfer or delegate this Agreement or any of my rights or obligations hereunder. This Agreement shall bind my heirs,
executors, administrators, legal representatives and assigns This Agreement shall remain in effect for the benefit of any successor or assign of the business of the Company, and shall inure to the benefit of such successor or assign. If any

the parties, or, if incapable of such enforcement, shall be deemed to be deleted from this Agreement, and the remainder of this Agreement and such provisions as applied to other persons, places and circumstances shall remain in full force and

THIS LOAN AND SECURITY AGREEMENT (this “Agreement”) dated and effective as of June 29, 2018 (the
“Effective Date”) between SILICON VALLEY BANK, a California corporation (“Bank”), and SIENNA BIOPHARMACEUTICALS, INC., a Delaware corporation (“Borrower”), provides the terms on which Bank
shall lend to Borrower and Borrower shall repay Bank. The parties agree as follows: 
  

	 	1	 ACCOUNTING AND OTHER TERMS 

Accounting terms not defined in this Agreement shall be construed following GAAP. Calculations and determinations must be made
following GAAP. Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code to
the extent such terms are defined therein. 
  

	 	2	 LOAN AND TERMS OF PAYMENT 

2.1    Promise to Pay. Borrower hereby unconditionally promises to pay Bank the outstanding
principal amount of all Credit Extensions and accrued and unpaid interest thereon as and when due in accordance with this Agreement. 

2.1.1 Term Loans. 

(a)    Availability. On the Effective Date, subject to the terms and conditions of this Agreement,
Bank shall make one (1) term loan to Borrower in an aggregate original principal amount of Fifteen Million Dollars ($15,000,000.00) (the “Term A Loan”). During the Term B Draw Period, subject to the terms and conditions of this
Agreement, Borrower may request and Bank shall make one (1) term loan to Borrower in the amount of Fifteen Million Dollars ($15,000,000.00) (the “Term B Loan”). During the Term C Draw Period, subject to the terms and conditions
of this Agreement, Borrower may request and Bank shall make one (1) term loan to Borrower in the amount of Ten Million Dollars ($10,000,000.00) (the “Term C Loan” and, together with the Term A Loan and the Term B Loan, each a
“Term Loan,” and collectively, the “Term Loans”). 

(b)    Repayment. The Term Loans shall be “interest only” during the Interest-Only
Period, with interest due and payable on the first day of each month. Beginning on the Amortization Start Date, and continuing on the first day of each month thereafter, Borrower shall repay the Term Loans in
(i) thirty-six (36) equal installments of principal, plus (ii) monthly payments of accrued interest (each, a “Term Loan Payment”). Borrower’s final Term Loan Payment, due
on the Term Loan Maturity Date, shall include all outstanding principal and accrued and unpaid interest under the Term Loans and the Final Payment. Once repaid, the Term Loans may not be reborrowed. 

(c)    Prepayment. 

(i)    Voluntary. Borrower shall have the option to prepay all, but not less than all of the Term
Loans advanced by Bank under this Agreement, provided Borrower (a) delivers written notice to Bank of its election to prepay the Term Loans at least five (5) days prior to such prepayment (or such shorter period as agreed by Bank) and
(b) pays, on the date of such prepayment, (i) all outstanding principal, plus accrued and unpaid interest with respect to the Term Loans, (ii) the Final Payment, (iii) the Prepayment Fee and (iv) all other sums, if any, that
shall have become due and payable hereunder in connection with the Term Loans. 

(ii)    Involuntary. If the Term Loans are accelerated during the continuance of an Event of
Default, Borrower shall immediately pay to Bank an amount equal to the sum of (a) all outstanding principal, plus accrued and unpaid interest with respect to the Term Loans, (b) the Final Payment, (c) the Prepayment Fee and
(d) all other sums, if any, that shall have become due and payable hereunder in connection with the Term Loans. 

2.2    Intentionally Omitted. 

 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 greater of two and one half percentage points (2.50%) above the Prime Rate or seven and one quarter percentage points (7.25%), which interest shall be
payable monthly. Notwithstanding the foregoing, if the applicable rate of interest pursuant to this Section 2.3 is less than zero, such rate shall be deemed to be zero for purposes of this Agreement. 

(b)    Default Rate. Immediately upon the occurrence and during the continuance of an Event of
Default, Obligations shall bear interest at a rate per annum which is three percentage points (3.00%) above the rate that is otherwise applicable thereto (the “Default Rate”). Fees and expenses which are required to be paid by
Borrower pursuant to the Loan Documents (including, without limitation, Bank Expenses) but are not paid when due shall bear interest until paid at a rate equal to the highest rate applicable to the Obligations. 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 Bank. 

(c)    Adjustment to Interest Rate. Changes to the interest rate of any Credit Extension based on
changes to the Prime Rate shall be effective on the effective date of any change to the Prime Rate and to the extent of any such change.

month and shall be computed on the basis of a 360-day year for the actual number of days elapsed. In computing interest, (i) all payments received after 12:00 p.m. Pacific time on any day shall be deemed
received at the opening of business on the next Business Day, and (ii) the date of the making of any Credit Extension shall be included and the date of payment shall be excluded; provided, however, that if any Credit Extension is repaid on the
same day on which it is made, such day shall be included in computing interest on such Credit Extension.

and manner in which all payments with respect to the Obligations may be applied. Borrower shall have no right to specify the order or the accounts to which Bank shall allocate or apply any payments required to be made by Borrower to Bank or
otherwise received by Bank under this Agreement when any such allocation or application is not specified elsewhere in this Agreement. 

(c)    Bank shall debit, first, the Designated Deposit Account and if there are insufficient funds in the

 2.6    Withholding. Payments received
by Bank from Borrower under this Agreement 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 Bank, 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, Bank 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 Bank with proof reasonably satisfactory to Bank 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 Bank, to secure the payment and
performance in full of all of the Obligations, a continuing security interest in, and pledges to Bank, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. 

Borrower acknowledges that it previously has entered, and/or may in the future enter, into Bank Services Agreements with Bank.
Regardless of the terms of any Bank Services Agreement, Borrower agrees that any amounts Borrower owes Bank thereunder shall be deemed to be Obligations hereunder and that it is the intent of Borrower and Bank to have all such Obligations secured by
the first priority perfected security interest in the Collateral granted herein (subject only to Permitted Liens that are permitted pursuant to the terms of this Agreement to have superior priority to Bank’s Lien in this Agreement). 

If this Agreement is terminated, Bank’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 Bank’s obligation to make Credit Extensions has terminated, Bank shall, at the
sole cost and expense of Borrower, release its Liens in the Collateral and all rights therein shall revert to Borrower. In the event (x) all Obligations (other than inchoate indemnity obligations), except for Bank Services, are satisfied in
full, and (y) this Agreement is terminated, Bank shall terminate the security interest granted herein upon Borrower providing cash collateral acceptable to Bank in its good faith business judgment for Bank Services, if any. In the event such
Bank Services consist of outstanding Letters of Credit, Borrower shall provide to Bank cash collateral in an amount equal to (x) if such Letters of Credit are denominated in Dollars, then at least one hundred five percent (105.00%); and
(y) if such Letters of Credit are denominated in a Foreign Currency, then at least one hundred ten percent (110.00%), of the Dollar Equivalent of the face amount of all such Letters of Credit plus all interest, fees, and costs due or to become
due in connection therewith (as estimated by Bank in its business judgment), to secure all of the Obligations relating to such Letters of Credit. 

4.2    Priority of Security Interest. Borrower represents, warrants, and 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 pursuant to the terms of this Agreement to have superior
priority to Bank’s Lien under this Agreement). If Borrower acquires a commercial tort claim greater than One Hundred Thousand Dollars ($100,000), Borrower shall promptly notify Bank in a writing signed by Borrower of the general details thereof
and grant to Bank 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 Bank. 

4.3    Authorization to File Financing Statements. Borrower hereby authorizes Bank to file
financing statements, without notice to Borrower, with all appropriate jurisdictions to perfect or protect Bank’s interest or rights hereunder. 
  

	 	5	 REPRESENTATIONS AND WARRANTIES 

Borrower represents and warrants as follows: 

5.1    Due Organization, Authorization; Power and Authority. Borrower is duly existing and
in good standing as a Registered Organization in its jurisdiction of formation and is qualified and licensed to do business and is in good standing in any jurisdiction in which the conduct of its business or its ownership of property requires that
it be qualified except where the failure to do so could not reasonably be expected to have a material adverse effect on Borrower’s business. In connection with this Agreement, Borrower has delivered to Bank completed certificates each signed by
Borrower, entitled “Perfection Certificate”. Borrower represents and warrants to Bank that (a) Borrower’s exact legal name is that indicated on the Perfection Certificate and on the signature page hereof; (b) Borrower is an
organization of the type and is organized in the jurisdiction set forth in the Perfection Certificate; (c) the Perfection Certificate accurately sets forth Borrower’s organizational identification number or accurately states that Borrower
has none; (d) the Perfection Certificate accurately sets forth Borrower’s place of business, or, if more than one, its chief executive office as well as Borrower’s mailing addresses (if different than its chief executive office);
(e) Borrower (and each of its predecessors) has not, in the past five (5) years, changed its jurisdiction of formation, organizational structure or type, or any organizational number assigned by its jurisdiction; and (f) all other
information set forth on the Perfection Certificate pertaining to Borrower and each of its Subsidiaries is accurate and complete (it being understood and agreed that Borrower may from time to time update certain information in the Perfection
Certificate after the Effective Date to the extent permitted by one or more specific provisions in this Agreement). If Borrower is not now a Registered Organization but later becomes one, Borrower shall promptly notify Bank of such occurrence and
provide Bank with Borrower’s organizational identification number. 

  
 -5- 

 The execution, delivery and performance by Borrower of the Loan Documents to
which it is a party have been duly authorized, and do not (i) conflict with any of Borrower’s organizational documents, (ii) contravene, conflict with, constitute a default under or violate any material Requirement of Law,
(iii) contravene, conflict or violate any applicable order, writ, judgment, injunction, decree, determination or award of any Governmental Authority by which Borrower or any of its Subsidiaries or any of their property or assets may be bound or
affected, (iv) require any action by, filing, registration, or qualification with, or Governmental Approval from, any Governmental Authority (except such Governmental Approvals which have already been obtained and are in full force and effect)
or (v) conflict with, contravene, constitute a default or breach under, or result in or permit the termination or acceleration of, any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which it is
a party or by which it is bound in which the default could reasonably be expected to have a material adverse effect on Borrower’s business. 

5.2    Collateral. Borrower has good title to, rights in, and the power to transfer each
item of the Collateral upon which it purports to grant a Lien hereunder, free and clear of any and all Liens except Permitted Liens. Borrower has no Collateral Accounts at or with any bank or financial institution other than Bank or Bank’s
Affiliates except for the Collateral Accounts described in the Perfection Certificate delivered to Bank in connection herewith and which Borrower has taken such actions as are necessary to give Bank a perfected security interest therein, pursuant to
the terms of Section 6.6(b). The Accounts are bona fide, existing obligations of the Account Debtors. 
 The Collateral
is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the Perfection Certificate. None of the components of the Collateral shall be maintained at locations other than as provided in the Perfection
Certificate or as permitted pursuant to Section 7.2. 
 Borrower is the sole owner of the Intellectual Property which
has any material value and which it owns or purports to own except for (a) licenses permitted hereunder, (b) over-the-counter software that is commercially
available to the public, (c) material Intellectual Property licensed to Borrower and noted on the Perfection Certificate or by giving notice in accordance with this Agreement and (d) as otherwise described in the Perfection Certificate. To
Borrower’s knowledge, each Patent (other than patent applications) which it owns or purports to own and which is material to Borrower’s business is valid and enforceable, and no part of the Intellectual Property which Borrower owns or
purports to own and which is material to Borrower’s business has been judged invalid or unenforceable, in whole or in part. To the best of Borrower’s knowledge, no claim has been made that any part of the Intellectual Property violates the
rights of any third party except to the extent such claim would not reasonably be expected to have a material adverse effect on Borrower’s business. 

5.3    Litigation. Other than those of which Borrower has notified Bank in the Perfection
Certificate or pursuant to Section 6.2(g), there are no actions or proceedings pending or, to the knowledge of any Responsible Officer, threatened in writing by or against Borrower or any Subsidiary that could reasonably be expected to cause a
Material Adverse Change. 
 5.4    Financial Statements; Financial Condition. All
consolidated financial statements for Borrower and any of its Subsidiaries delivered to Bank fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s consolidated results of operations. There has
not been any material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements submitted to Bank. 

5.5    Solvency. The fair salable value of Borrower’s consolidated assets (including
goodwill minus disposition costs) exceeds the fair value of Borrower’s liabilities; Borrower is not left with unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as
they mature. 
 5.6    Regulatory Compliance. Borrower is not an “investment
company” or a company “controlled” by an “investment company” under the Investment Company Act of 1940, as amended. Borrower is not engaged as one of its important activities in extending credit for margin stock (under
Regulations X, T and U of the Federal Reserve Board of Governors). Borrower (a) has complied in all material respects with all Requirements of Law, and (b) has not violated any Requirements of Law the violation of which could reasonably be
expected to have a material adverse effect on its business. None of Borrower’s or any of its Subsidiaries’ properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons,
in disposing, producing, storing, treating, or transporting any hazardous substance other than legally. Borrower and each of its Subsidiaries has obtained all consents, approvals and authorizations of, made all declarations or filings with, and
given all notices to, all Government Authorities that are necessary to continue their respective businesses as currently conducted, except to the extent that failure to do so could not reasonably be expected to have a material adverse effect on its
business or impair Borrower’s performance of the Obligations. 

  
 -6- 

 5.7    Subsidiaries; Investments. Borrower does
not own any stock, partnership, or other ownership interest or other equity securities except for Permitted Investments. 

5.8    Tax Returns and Payments; Pension Contributions. Borrower has timely filed all
required tax returns and reports, and Borrower has timely paid all foreign, federal, state and local taxes, assessments, deposits and contributions owed by Borrower except (a) to the extent such taxes are being contested in good faith by
appropriate proceedings promptly instituted and diligently conducted, so long as such reserve or other appropriate provision, if any, as shall be required in conformity with GAAP shall have been made therefor, or (b) if such taxes, assessments,
deposits and contributions do not, individually or in the aggregate, exceed Two Hundred Fifty Thousand Dollars ($250,000). 

To the extent Borrower defers payment of any contested taxes, Borrower shall (i) notify Bank in writing of the
commencement of, and any material development in, the proceedings, and (ii) post bonds or take any other steps reasonably required to prevent the governmental authority levying such contested taxes from obtaining a Lien upon any of the
Collateral that is other than a “Permitted Lien.” Borrower is unaware of any claims or adjustments proposed for any of Borrower’s prior tax years which could result in additional taxes becoming due and payable by Borrower in excess of
Fifty Thousand Dollars ($50,000). Borrower has paid all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms, and Borrower has not withdrawn from participation in, and has not
permitted partial or complete termination of, or permitted the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any material liability of Borrower, including any material liability to the
Pension Benefit Guaranty Corporation or its successors or any other Governmental Authority. 

5.9    Use of Proceeds. Borrower shall use the proceeds of the Credit Extensions solely as
working capital and to fund its general business requirements and not for personal, family, household or agricultural purposes. 

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

5.11    Definition of “Knowledge.” For purposes of the Loan Documents, whenever a
representation or warranty is made to Borrower’s knowledge or awareness, to the “best of” Borrower’s knowledge, or with a similar qualification, knowledge or awareness means the actual knowledge, after reasonable investigation,
of any Responsible Officer.

6.5    Insurance. 

(a)    Keep its business and the Collateral insured for risks and in amounts standard for companies in
Borrower’s industry and location and as Bank may reasonably request. Insurance policies shall be in a form, with financially sound and reputable insurance companies that are not Affiliates of Borrower, and in amounts that are reasonably
satisfactory to Bank. All property policies shall have a lender’s loss payable endorsement showing Bank as lender loss payee. All liability policies shall show, or have endorsements showing, Bank as an additional insured. Bank shall be named as
lender loss payee and/or additional insured with respect to any such insurance providing coverage in respect of any Collateral. 

(b)    Ensure that proceeds payable under any property policy are, at Bank’s option, payable to Bank

independent instruments furnished to Bank, that it will give Bank thirty (30) days prior written notice (ten (10) days for cancellation as a result of nonpayment of premium) before any such policy or policies shall be canceled. If Borrower

Section 6.5, and take any action under the policies Bank deems prudent.

(a)    Maintain all of its and all of its Domestic Subsidiaries’ cash, Cash Equivalents, and primary
Bank Services with Bank or Bank’s Affiliates. 
 (b)    Provide Bank five (5) days prior
written notice before establishing any Collateral Account at or with any bank or financial institution other than Bank or Bank’s Affiliates. For each Collateral Account that Borrower at any time maintains, Borrower shall cause the applicable
bank or financial institution (other than Bank) at or with which any Collateral Account is maintained to execute and deliver a Control Agreement or other appropriate instrument with respect to such Collateral Account to perfect Bank’s Lien in
such Collateral Account in accordance with the terms hereunder which Control Agreement may not be terminated without the prior written consent of Bank. The provisions of the previous sentence shall not apply to deposit accounts exclusively used for
payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of Borrower’s employees and identified to Bank by Borrower as such. 

6.7    SNA Milestone. If Borrower requests and Bank makes the Term B Loan and Borrower fails
to achieve the Term C Draw Period Milestone 2 by no later than March 31, 2019, then Borrower shall immediately cash secure not less than the lesser of the outstanding balance or Fifteen Million Dollars ($15,000,000) of the principal balance of
all outstanding Indebtedness under the Term Loans in the Pledged Account (a “Cash Collateralization”) until such time that Borrower has achieved the Cash Collateralization Release Milestone. Borrower hereby authorizes and directs Bank to
transfer to the Pledged Account an amount equal to Fifteen Million Dollars ($15,000,000) if Borrower fails to maintain compliance with Section 6.7, it being understood that the foregoing authorization shall constitute an immediate Cash
Collateralization, irrespective of any delay by Bank in effecting such transfer, to the extent that sufficient Borrower funds are then available for Bank to effect such transfer. Failure to comply with the Cash Collateralization requirement above
shall result in an immediate Event of Default. 
 6.8    Protection of Intellectual Property
Rights. (i) Protect, defend and maintain the validity and enforceability of its Intellectual Property that is material to Borrower’s business; (ii) promptly advise Bank in writing of material infringements or any other event that

without Bank’s written consent. 
 6.9    Litigation Cooperation. From the date hereof
and continuing through the termination of this Agreement, make available to Bank, without expense to Bank, Borrower and its officers, employees and agents and Borrower’s books and records, to the extent that Bank may deem them reasonably
necessary to prosecute or defend any third-party suit or proceeding instituted by or against Bank with respect to any Collateral or relating to Borrower. 

6.10    Access to Collateral; Books and Records. Allow Bank, or its agents, at reasonable
times, on three (3) Business Day’s notice (provided no notice is required if an Event of Default has occurred and is continuing), to inspect the Collateral and audit and copy Borrower’s Books. Such inspections or audits shall be
conducted no more often than once every twelve (12) months unless an Event of Default has occurred and is continuing in which case such inspections and audits shall occur as often as Bank shall reasonably determine is necessary. The foregoing
inspections and audits shall be at Borrower’s expense, and the charge therefor shall be One Thousand Dollars ($1,000) per person per day (or such higher amount as shall represent Bank’s then-current standard charge for the same), plus
reasonable out-of-pocket expenses. In the event Borrower and Bank schedule an audit more than eight (8) days in advance, and Borrower cancels or seeks to or
reschedules the audit with less than eight (8) days written notice to Bank, then (without limiting any of Bank’s rights or remedies) Borrower shall pay Bank a fee of Two Thousand Dollars ($2,000) plus any out-of-pocket expenses incurred by Bank to compensate Bank for the anticipated costs and expenses of the cancellation or rescheduling. 

6.11    Formation or Acquisition of Subsidiaries. Notwithstanding and without limiting the
negative covenants contained in Sections 7.3 and 7.7 hereof, around the time that Borrower forms any direct or indirect Subsidiary or acquires any direct or indirect Subsidiary after the Effective Date, Borrower shall upon Bank’s reasonable
request (a) cause such new Domestic Subsidiary to provide to Bank a joinder to this Agreement to cause such new Domestic Subsidiary to become Borrower hereunder, together with such appropriate financing statements and/or Control Agreements, all
in form and substance reasonably satisfactory to Bank (including being sufficient to grant Bank a first priority Lien (subject to Permitted Liens) in and to the assets of such newly formed or acquired Domestic Subsidiary), (b) provide to Bank
appropriate certificates and powers and financing statements, pledging all of the direct or beneficial ownership interest in such new Domestic Subsidiary, in form and substance reasonable satisfactory to Bank; provided, that with respect to any
Foreign Subsidiary, Borrower shall only be required to grant and pledge to Bank a perfected security interest in up to sixty-five percent (65%) of the stock, units or other evidence of ownership of such Foreign Subsidiary; and (c) provide to
Bank all other documentation in form and substance reasonably satisfactory to Bank which in its opinion is appropriate with respect to the execution and delivery of the applicable documentation referred to above. Any document, agreement, or
instrument executed or issued pursuant to this Section 6.11 shall be a Loan Document.

 6.12    Further Assurances. Execute any further
instruments and take further action as Bank reasonably requests to perfect or continue Bank’s Lien in the Collateral or to effect the purposes of this Agreement.

(including, without limitation, by the formation of any Subsidiary) other than Permitted Investments, or permit any of its Subsidiaries to do so. 

7.8    Transactions with Affiliates. Directly or indirectly enter into or permit to exist
any material transaction with any Affiliate of Borrower, except for (a) 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, (b) Subordinated Debt, (c) compensation-related transactions in the ordinary course of business or otherwise as approved by Borrower’s
board of directors or by Bank, (d) distributions permitted under Section 7.7, Transfers permitted hereunder and Permitted Investments, and (e) equity investments in Borrower or its Subsidiaries.

complete termination of, or permit the occurrence of any other event with respect to, any present pension, profit sharing and deferred compensation plan which could reasonably be expected to result in any liability of Borrower, including any
liability to the Pension Benefit Guaranty Corporation or its successors or any other Governmental Authority.

interest on any Credit Extension when due, or (b) pay any other Obligations within three (3) Business Days after such Obligations are due and payable (which three (3) Business Day cure period shall not apply to payments due on the

	 	8.2	 Covenant Default. 

(a)    Borrower fails or neglects to perform any obligation in Sections 6.2, 6.4, 6.5, 6.6, 6.7, 6.10, or

 (b)    Borrower fails or neglects to perform,

covenant or agreement that can be cured, have failed to cure the default within ten (10) days after the occurrence thereof; provided, however, that if the default cannot by its nature be cured within 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). Cure periods provided under this section
shall not apply, among other things, to financial covenants or any other covenants set forth in clause (a) above; 

8.3    Material Adverse Change. A Material Adverse Change occurs;

(b)    (i) any material portion of Borrower’s assets is attached, seized, levied on, or comes into
possession of a trustee or receiver, or (ii) any court order enjoins, restrains, or prevents Borrower from conducting all or any material part of its business;

clause (a) exist and/or until any Insolvency Proceeding is dismissed); 
 8.6    Other
Agreements. There is, under any agreement to which Borrower or any Guarantor is a party with a third party or parties, (a) any default resulting in a right by such third party or parties, whether or not exercised, to accelerate the maturity
of any Indebtedness in an amount individually or in the aggregate in excess of Five Hundred Thousand Dollars ($500,000); or (b) any breach or default by Borrower, the result of which could have a material adverse effect on Borrower’s
business; 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 Bank 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) Bank 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 Bank be materially less advantageous to Borrower; 

  
 -13- 

 8.7    Judgments; Penalties. One or more fines,
penalties or final judgments, orders or decrees for the payment of money in an amount, individually or in the aggregate, of at least Five Hundred Thousand Dollars ($500,000) (not covered by independent third-party insurance as to which liability has
been accepted by such insurance carrier) shall be rendered against Borrower by any Governmental Authority, and the same are not, within ten (10) days after the entry, assessment or issuance thereof, discharged, satisfied, or paid, or after
execution thereof, stayed or bonded pending appeal, or such judgments are not discharged prior to the expiration of any such stay (provided that no Credit Extensions will be made prior to the satisfaction, payment, discharge, stay, or bonding of
such fine, penalty, judgment, order or decree);

further liability or obligation thereunder, or the Obligations shall for any reason be subordinated or shall not have the priority contemplated by this Agreement, except, in each case, as may be permitted pursuant to the terms of such subordination
agreement between such Person and Bank; 
 8.10  Governmental Approvals. Any Governmental Approval shall
have been (a) revoked, rescinded, suspended, modified in an adverse manner or not renewed in the ordinary course for a full term or (b) subject to any decision by a Governmental Authority that designates a hearing with respect to any
applications for renewal of any of such Governmental Approval or that could result in the Governmental Authority taking any of the actions described in clause (a) above, and such decision or such revocation, rescission, suspension, modification
or non-renewal (i) cause, or could reasonably be expected to cause, a Material Adverse Change, or (ii) adversely affects the legal qualifications of Borrower or any of its Subsidiaries to hold such
Governmental Approval in any applicable jurisdiction and such revocation, rescission, suspension, modification or non-renewal could reasonably be expected to affect the status of or legal qualifications of
Borrower or any of its Subsidiaries to hold any Governmental Approval in any other jurisdiction. 
  

	 	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, without notice or demand, do any or all of the following: 
 (a)    declare all
Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations are immediately due and payable without any action by Bank); 

(b)    stop advancing money or extending credit for Borrower’s benefit under this Agreement or under
any other agreement between Borrower and Bank; 
 (c)    for any letters of credit demand that Borrower
(i) deposit cash with Bank in an amount equal to at least one hundred five percent (105%) of the Dollar Equivalent of the aggregate face amount of all Letters of Credit denominated in Dollars remaining undrawn, and (y) one hundred ten
percent (110%) of the Dollar Equivalent of the aggregate face amount of all Letters of Credit denominated in a Foreign Currency remaining undrawn (plus, in each case all interest, fees, and costs due or to become due in connection therewith (as
estimated by Bank in its good faith business judgment)), to secure all of the Obligations relating to such Letters of Credit, as collateral security for the repayment of any future drawings under such Letters of Credit, and Borrower shall forthwith
deposit and pay such amounts, and (ii) pay in advance all letter of credit fees scheduled to be paid or payable over the remaining term of any Letters of Credit; 

  
 -14- 

 (d)    terminate any FX Contracts; 

(e)    verify the amount of, demand payment of and performance under, and collect any Accounts and General
Intangibles, settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Bank considers advisable, and notify any Person owing Borrower money of Bank’s security interest in such funds; 

(f)    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 Bank requests and make it available as Bank designates. Bank 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 Bank a license to enter and occupy any of its premises, without charge,
to exercise any of Bank’s rights or remedies; 
 (g)    apply to the Obligations any
(i) balances and deposits of Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or the account of Borrower; 

(h)    ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and
sell the Collateral. Bank is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s labels, Patents, Copyrights, mask works, rights of use of any name,
trade secrets, trade names, Trademarks, 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 Bank’s exercise of
its rights under this Section, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit; 

(i)    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; 

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

(k)    exercise all rights and remedies available to Bank 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). 

9.2    Power of Attorney. Borrower hereby irrevocably appoints Bank as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s name on any checks or other forms of
payment or security; (b) sign Borrower’s 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 Bank 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 Bank or a third party as the Code permits. Borrower hereby appoints Bank as its lawful attorney-in-fact to sign Borrower’s name on any documents necessary to perfect or continue the perfection of Bank’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 Bank is under no further obligation to make Credit Extensions hereunder. Bank’s foregoing appointment as
Borrower’s attorney in fact, and all of Bank’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 Bank’s obligation
to provide Credit Extensions terminates. 

  
 -15- 

 9.3    Protective Payments. If Borrower fails
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 is obligated to pay under this Agreement or any other Loan Document or which may be required to preserve the
Collateral, Bank may obtain such insurance or make such payment, and all amounts so paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then highest rate applicable to the Obligations, and secured by the
Collateral. Bank will make reasonable efforts to provide Borrower with notice of Bank obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No payments by Bank are deemed an agreement to make similar payments in
the future or Bank’s waiver of any Event of Default. 
 9.4    Application of Payments
and Proceeds Upon Default. If an Event of Default has occurred and is continuing, Bank shall have the right to apply in any order any funds in its possession, whether from Borrower’s account balances, payments, proceeds realized as the
result of any collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations. Bank shall pay any surplus to Borrower by credit to the Designated Deposit Account or to other Persons legally entitled thereto; Borrower
shall remain liable to Bank for any deficiency. If Bank, directly or indirectly, enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Bank shall have the option, exercisable at any time, of either
reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by Bank of cash therefor. 

9.5    Bank’s Liability for Collateral. So long as Bank complies with reasonable
banking practices regarding the safekeeping of the Collateral in the possession or under the control of Bank, Bank 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. Bank’s failure, 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 Bank thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder
shall be effective unless signed by the party granting the waiver and then is only effective for the specific instance and purpose for which it is given. Bank’s rights and remedies under this Agreement and the other Loan Documents are
cumulative. Bank has all rights and remedies provided under the Code, by law, or in equity. Bank’s exercise of one right or remedy is not an election and shall not preclude Bank from exercising any other remedy under this Agreement or other
remedy available at law or in equity, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay in exercising any remedy is not a waiver, election, or acquiescence. 

9.7    Demand Waiver. Borrower waives 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 Bank on which Borrower is liable.

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

Except as otherwise expressly provided in any of the Loan Documents, California law governs the Loan Documents without regard
to principles of conflicts of law. Borrower and Bank 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 Bank 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 Bank. Borrower expressly
submits and consents in advance to such jurisdiction in any 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 AND BANK 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 BOTH PARTIES 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

representations and warranties made in this Agreement continue in full force until this Agreement has terminated pursuant to its terms and all Obligations have been satisfied. So long as Borrower has satisfied its Obligations (other than inchoate
indemnity obligations, any other obligations which, by their terms, are to survive the termination of this Agreement, and any Obligations under Bank Services Agreements that are cash collateralized in accordance with Section 4.1 of this
Agreement), this Agreement may be terminated prior to the Term Loan Maturity Date by Borrower, effective three (3) Business Days after written notice of termination is given to Bank. Those obligations that are expressly specified in this
Agreement as surviving this Agreement’s termination shall continue to survive notwithstanding this Agreement’s termination. 

12.2    Successors and Assigns. This Agreement binds and is for the benefit of the
successors and permitted assigns of each party. Borrower may not assign this Agreement or any rights or obligations under it without Bank’s prior written consent (which may be granted or withheld in Bank’s discretion). Bank has the right,
without the consent of or notice to Borrower, to sell, transfer, assign, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights, and benefits under this Agreement and the other Loan Documents.
Notwithstanding the foregoing, prior to the occurrence of an Event of Default that is continuing, Bank shall not assign any interest in the Loan Documents to any Person who in the reasonable estimation of Bank is (a) a direct competitor of
Borrower, whether as an operating company or direct or indirect parent with voting control over such operating company, or (b) a vulture fund or distressed debt fund.

directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Bank (each, an “Indemnified Person”) harmless against: (i) all obligations, demands, claims, and liabilities (collectively,
“Claims”) claimed or asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (ii) all losses or reasonable and documented expenses (including Bank Expenses) in any way suffered,
incurred, or paid by such Indemnified Person as a result of, following from, consequential to, or arising from transactions between Bank 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. 
 This Section 12.3 shall survive

12.4    Time of Essence. Time is of the essence for the performance of all Obligations in
this Agreement. 
 12.5    Severability of Provisions. Each provision of this Agreement is
severable from every other provision in determining the enforceability of any provision.

in the Loan Documents consistent with the agreement of the parties so long as Bank provides Borrower with written notice of such correction and allows Borrower at least ten (10) days to object to such correction. In the event of such objection,
such correction shall not be made except by an amendment signed by both Bank and Borrower. 

12.7    Amendments in Writing; Waiver; Integration. No purported amendment or modification
of any Loan Document, or waiver, discharge or termination of any obligation under any Loan Document, shall be enforceable or admissible unless, and only to the extent, expressly set forth in a writing signed by the party against which enforcement or
admission is sought. Without limiting the generality of the foregoing, no oral promise or statement, nor any action, inaction, delay, failure to require performance or course of conduct shall operate as, or evidence, an amendment, supplement or
waiver or have any other effect on any Loan Document. Any waiver granted shall be limited to the specific circumstance expressly described in it, and shall not apply to any subsequent or other circumstance, whether similar or dissimilar, or give
rise to, or evidence, any obligation or commitment to grant any further waiver. The Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements. All prior agreements, understandings,
representations, warranties, and negotiations between the parties about the subject matter of the Loan Documents merge into the Loan Documents.

 EXHIBIT A 

COLLATERAL DESCRIPTION 

The Collateral consists of all of Borrower’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 provided below), commercial tort claims, documents, instruments (including any promissory notes), chattel paper (whether tangible or electronic), cash, deposit
accounts, 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 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 any of the following: (a) any interest of Borrower as a
lessee or sublessee under a real property lease; (b) rights held under a license that are not assignable by their terms without the consent of the licensor thereof (but only to the extent such restriction on assignment is enforceable under
applicable law); (c) any interest of Borrower as a lessee under an Equipment lease if Borrower is prohibited by the terms of such lease from granting a security interest in such lease or under which such an assignment or Lien would cause a default
to occur under such lease, provided, however, that upon termination of such prohibition, such interest shall immediately become Collateral without any action by Borrower or Bank; (d) more than 65% of the presently existing and hereafter arising
issued and outstanding shares of capital stock owned by Borrower of any Foreign Subsidiary that is not an entity organized under the laws of the United States or any state thereof, which shares entitle the holder thereof to vote for directors or any
other matter; or (e) 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 Bank’s security interest in such Accounts and such other property of Borrower that are proceeds of the Intellectual Property. 

Pursuant to the terms of a certain negative pledge arrangement with Bank, Borrower has agreed not to encumber any of its
Intellectual Property without Bank’s prior written consent.
