 Exhibit 10.1 
  
 LOAN AND SECURITY AGREEMENT 
  

THIS LOAN AND SECURITY AGREEMENT (this “Agreement”) dated as of the Effective Date between SILICON VALLEY BANK, a
California corporation (“Bank”), and ISTA PHARMACEUTICALS, 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. 
  
 2.2 Revolving Advances. 
  
 (a) Availability. Subject to the terms and conditions of this Agreement, Bank shall make Advances not exceeding the Revolving Line. Amounts borrowed under the Revolving Line may be repaid and, prior to the
Revolving Line Maturity Date, reborrowed, subject to the applicable terms and conditions precedent herein. 
  
 (b) Termination; Repayment. The Revolving Line terminates on the Revolving Line Maturity Date, when the principal amount of all
Advances, the unpaid interest thereon, and all other Obligations relating to the Revolving Line shall be immediately due and payable. 
  
 2.3 Overadvances. If, at any time, the Advances under Section 2.2 exceed the Revolving Line, Borrower shall immediately pay to Bank in cash
such excess. 
  
 2.4 General Provisions Relating to the
Advances. Each Advance shall, at Borrower’s option in accordance with the terms of this Agreement, be either in the form of a Prime Rate Advance or a LIBOR Advance. Borrower shall pay interest accrued on the Advances at the rates and in the
manner set forth in Section 2.5.  
  
 2.5 Payment
of Interest on the Credit Extensions. 
  
 (a)
Computation of Interest. Interest on the Credit Extensions and all fees payable hereunder shall be computed on the basis of a 360-day year and the actual number of days elapsed in the period during which such interest accrues. In computing
interest on any Credit Extension, the date of the making of such 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. 
  
 (b) Advances. Each Advance shall bear interest on the outstanding principal amount thereof from the date when made, continued or converted until paid in full at a rate per annum equal to the Prime Rate or the
LIBOR Rate plus the LIBOR Rate Margin, as the case may be. On and after the expiration of any Interest Period applicable to any LIBOR Advance outstanding on the date of occurrence of an Event of Default or acceleration of the Obligations, the
Effective Amount of such LIBOR Advance shall, during the continuance of such Event of Default or after acceleration, bear interest at a rate per annum equal to the Prime Rate plus five percent (5.00%). Pursuant to the terms hereof, interest on each
Advance shall be paid in arrears on each Interest Payment Date. 

  

 1 

 
Interest shall also be paid on the date of any prepayment of any Advance pursuant to this Agreement for the portion of any Advance so prepaid and upon
payment (including prepayment) in full thereof. All accrued but unpaid interest on the Advances shall be due and payable on the Revolving Line Maturity Date. 
  

(c) Default Interest. Except as otherwise provided in Section 2.5(b), after an Event of Default, Obligations shall bear
interest five percent (5.00%) above the rate effective immediately before the Event of Default (the “Default Rate”). Payment or acceptance of the increased interest provided in this Section 2.5(c) 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. 
  
 (d) Prime Rate Advances. Each change in the interest rate of the Prime Rate Advances based on changes in the Prime Rate shall be
effective on the effective date of such change and to the extent of such change. Bank shall use its best efforts to give Borrower prompt notice of any such change in the Prime Rate; provided, however, that any failure by Bank to provide Borrower
with notice hereunder shall not affect Bank’s right to make changes in the interest rate of the Prime Rate Advances based on changes in the Prime Rate. 
  
 (e) LIBOR Advances. The interest rate applicable to each LIBOR Advance shall be determined in accordance with
Section 3.6(a) hereunder. Subject to Sections 3.6 and 3.7, such rate shall apply during the entire Interest Period applicable to such LIBOR Advance, and interest calculated thereon shall be payable on the Interest Payment
Date applicable to such LIBOR Advance. 
  
 (f)
Debit of Accounts. Bank may debit any of Borrower’s deposit accounts, including the Designated Deposit Account, for principal and interest payments when due, or any other amounts Borrower owes Bank, when due. Bank shall promptly notify
Borrower after it debits Borrower’s accounts. These debits shall not constitute a set-off. 
  
 2.6 Fees. Borrower shall pay to Bank: 
  
 (a) Commitment Fee. A fully earned, non-refundable commitment fee of $6,250, on the Effective Date; 
  
 (b) Renewal Fee. A renewal fee of $25,000 due and
payable on the Renewal Date unless this Agreement is terminated on or before the Renewal Date; and 
  
 (c) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses, plus expenses, for documentation and
negotiation of this Agreement) incurred through and after the Effective Date, when due. 
  

	 	3	CONDITIONS OF LOANS 

  
 3.1 Conditions Precedent to Initial Advance. Bank’s obligation to make the initial Advance is subject to the condition precedent that Bank
shall have received, in form and substance satisfactory to Bank, such documents, and completion of such other matters, as Bank may reasonably deem necessary or appropriate, including, without limitation: 
  
 (a) Borrower shall have delivered duly executed original
signatures to the Loan Documents to which it is a party; 
  
 (b) Borrower shall have delivered duly executed original signatures to the Control Agreements; 
  
 (c) Borrower shall have delivered its Operating Documents and a good standing certificate of Borrower certified by the Secretary of State
of the State of Delaware as of a date no earlier than thirty (30) days prior to the Effective Date; 
  

 2 

 (d) Borrower shall have delivered the Perfection Certificate(s) executed by Borrower;

  
 (e) Borrower shall have delivered duly
executed original signatures to the completed Borrowing Resolutions for Borrower; 
  
 (f) Borrower shall have delivered the insurance policies and/or endorsements required pursuant to Section 6.4 hereof are in full
force and effect, together with appropriate evidence showing loss payable and/or additional insured clauses or endorsements in favor of Bank; and 
  
 (g) Borrower shall have paid the fees and Bank Expenses then due as specified in Section 2.5 hereof. 
  
 3.2 Conditions Precedent to all Credit Extensions. Bank’s
obligations to make each Credit Extension, including the initial Credit Extension, is subject to the following: 
  
 (a) timely receipt of a Notice of Borrowing; and 
  

(b) the representations and warranties in Section 5 shall be true in all material respects on the date of the Notice of Borrowing,
and on the effective date of each Credit Extension; provided, however, that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof; and
provided, further that those representations and warranties expressly referring to a specific date shall be true, accurate and complete in all material respects as of such date, and no Event of Default shall have occurred and be continuing or result
from the Credit Extension. Each Credit Extension is Borrower’s representation and warranty on that date that the representations and warranties in Section 5 remain true in all material respects; provided, however, that such materiality
qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof; and provided, further that those representations and warranties expressly referring to a specific date
shall be true, accurate and complete in all material respects as of such date. 
  
 (c) in Bank’s sole discretion, there has not been a Material Adverse Change. 
  
 3.3 Covenant to Deliver. 
  
 Borrower agrees to deliver to Bank each item required to be delivered to Bank
under this Agreement as a condition to any Credit Extension. Borrower expressly agrees that the extension of a Credit Extension prior to the receipt by Bank of any such item shall not constitute a waiver by Bank of Borrower’s obligation to
deliver such item, and any such extension in the absence of a required item shall be in Bank’s sole discretion. 
  
 3.4 Procedures for Borrowing. 
  
 (a) Subject to the prior satisfaction of all other applicable conditions to the making of an Advance set forth in this Agreement, each
Advance shall be made upon Borrower’s irrevocable written notice delivered to Bank in the form of a Notice of Borrowing, each executed by a Responsible Officer of Borrower or his or her designee or without instructions if the Advances are
necessary to meet Obligations which have become due. Bank may rely on any telephone notice given by a person whom Bank believes is a Responsible Officer or designee. Borrower will indemnify Bank for any loss Bank suffers due to such reliance. Such
Notice of Borrowing must be received by Bank prior to 11:00 a.m. Pacific time, (i) at least three (3) Business Days prior to the requested Funding Date, in the case of LIBOR Advances, and (ii) at least one (1) Business Day prior
to the requested Funding Date, in the case of Prime Rate Advances, specifying: 
  
 (i) the amount of the Advance, which, if a LIBOR Advance is requested, shall be in an aggregate minimum principal amount of $500,000 or in
any integral multiple of $500,000 in excess thereof; 
  
 (ii) the requested Funding Date; 
  

 3 

 (iii) whether the Advance is to be comprised of LIBOR Advances or Prime Rate Advances;
and 
  
 (iv) the duration of the Interest Period
applicable to any such LIBOR Advances included in such notice; provided that if the Notice of Borrowing shall fail to specify the duration of the Interest Period for any Advance comprised of LIBOR Advances, such Interest Period shall be one
(1) month. 
  
 (b) The proceeds of all such
Advances will then be made available to Borrower on the Funding Date by Bank by transfer to the Designated Deposit Account and, subsequently, by wire transfer to such other account as Borrower may instruct in the Notice of Borrowing. No Advances
shall be deemed made to Borrower, and no interest shall accrue on any such Advance, until the related funds have been deposited in the Designated Deposit Account. 
  
 3.5 Conversion and Continuation Elections. 
  
 (a) So long as (i) no Event of Default or Default exists; (ii) Borrower shall not have sent any
notice of termination of this Agreement; and (iii) Borrower shall have complied with such customary procedures as Bank has established from time to time for Borrower’s requests for LIBOR Advances, Borrower may, upon irrevocable written
notice to Bank: 
  
 (i) elect to convert on any
Business Day, Prime Rate Advances in an amount equal to $500,000 or any integral multiple of $500,000 in excess thereof into LIBOR Advances; 
  
 (ii) elect to continue on any Interest Payment Date any LIBOR Advances maturing on such Interest Payment Date (or any part thereof in an
amount equal to $500,000 or any integral multiple of $500,000 in excess thereof); provided, that if the aggregate amount of LIBOR Advances shall have been reduced, by payment, prepayment, or conversion of part thereof, to be less than $500,000, such
LIBOR Advances shall automatically convert into Prime Rate Advances, and on and after such date the right of Borrower to continue such Advances as, and convert such Advances into, LIBOR Advances shall terminate; or 
  
 (iii) elect to convert on any Interest Payment Date any
LIBOR Advances maturing on such Interest Payment Date (or any part thereof in an amount equal to $500,000 or any integral multiple of $500,000 in excess thereof) into Prime Rate Advances. 
  
 (b) Borrower shall deliver a Notice of
Conversion/Continuation in accordance with Section 10 to be received by Bank prior to 11:00 a.m. Pacific time at least (i) three (3) Business Days in advance of the Conversion Date or Continuation Date, if any Advances are to
be converted into or continued as LIBOR Advances; and (ii) one (1) Business Day in advance of the Conversion Date, if any Advances are to be converted into Prime Rate Advances, in each case specifying the: 
  
 (i) proposed Conversion Date or Continuation Date;

  
 (ii) aggregate amount of the Advances to be
converted or continued which, if any Advances are to be converted into or continued as LIBOR Advances, shall be in an aggregate minimum principal amount of $500,000 or in any integral multiple of $500,000 in excess thereof; 
  
 (iii) nature of the proposed conversion or continuation; and

  
 (iv) duration of the requested Interest
Period. 
  
 (c) If upon the expiration of any
Interest Period applicable to any LIBOR Advances, Borrower shall have timely failed to select a new Interest Period to be applicable to such LIBOR Advances, Borrower shall be deemed to have elected to convert such LIBOR Advances into Prime Rate
Advances. 
  

 4 

 (d) Any LIBOR Advances shall, at Bank’s option, convert into Prime Rate Advances in
the event that (i) an Event of Default or Default shall exist, or (ii) the aggregate principal amount of the Prime Rate Advances which have been previously converted to LIBOR Advances, or the aggregate principal amount of existing LIBOR
Advances continued, as the case may be, at the beginning of an Interest Period shall at any time during such Interest Period exceed the Revolving Line. Borrower agrees to pay Bank, upon demand by Bank (or Bank may, at its option, charge the
Designated Deposit Account or any other account Borrower maintains with Bank) any amounts required to compensate Bank for any loss, reasonable cost, or expense incurred by Bank, as a result of the conversion of LIBOR Advances to Prime Rate Advances
pursuant to any of the foregoing under clauses (i) and (ii) of this Section 3.5(d). 
  
 (e) Notwithstanding anything to the contrary contained herein, Bank shall not be required to purchase United States Dollar deposits in the
London interbank market or other applicable LIBOR market to fund any LIBOR Advances, but the provisions hereof shall be deemed to apply as if Bank had purchased such deposits to fund the LIBOR Advances. 
  
 3.6 Special Provisions Governing LIBOR Advances. 
  
 Notwithstanding any other provision of this Agreement to the contrary, the
following provisions shall govern with respect to LIBOR Advances as to the matters covered: 
  
 (a) Determination of Applicable Interest Rate. As soon as practicable on each Interest Rate Determination Date, Bank shall
determine (which determination shall, absent manifest error in calculation, be final, conclusive and binding upon all parties) the interest rate that shall apply to the LIBOR Advances for which an interest rate is then being determined for the
applicable Interest Period and shall promptly give notice thereof (in writing or by telephone confirmed in writing) to Borrower. 
  
 (b) Inability to Determine Applicable Interest Rate. In the event that Bank shall have determined (which determination shall be
final and conclusive and binding upon all parties hereto), on any Interest Rate Determination Date with respect to any LIBOR Advance, that by reason of circumstances affecting the London interbank market adequate and fair means do not exist for
ascertaining the interest rate applicable to such Advance on the basis provided for in the definition of LIBOR, Bank shall on such date give notice (by facsimile or by telephone confirmed in writing) to Borrower of such determination, whereupon
(i) no Advances may be made as, or converted to, LIBOR Advances until such time as Bank notifies Borrower that the circumstances giving rise to such notice no longer exist, and (ii) any Notice of Borrowing or Notice of
Conversion/Continuation given by Borrower with respect to Advances in respect of which such determination was made shall be deemed to be rescinded by Borrower. 
  

(c) Compensation for Breakage or Non-Commencement of Interest Periods. Borrower shall compensate Bank, upon written request by
Bank (which request shall set forth the manner and method of computing such compensation), for all reasonable losses, expenses and liabilities, if any (including any interest paid by Bank to lenders of funds borrowed by it to make or carry its LIBOR
Advances and any loss, expense or liability incurred by Bank in connection with the liquidation or re-employment of such funds) such that Bank may incur: (i) if for any reason (other than a default by Bank or due to any failure of Bank to fund
LIBOR Advances due to impracticability or illegality under Sections 3.7(d) and 3.7(e)) a borrowing or a conversion to or continuation of any LIBOR Advance does not occur on a date specified in a Notice of Borrowing or a Notice of
Conversion/Continuation, as the case may be, or (ii) if any principal payment or any conversion of any of its LIBOR Advances occurs on a date prior to the last day of an Interest Period applicable to that Advance. 
  
 (d) Assumptions Concerning Funding of LIBOR Advances.
Calculation of all amounts payable to Bank under this Section 3.6 and under Section 2.5 shall be made as though Bank had actually funded each of its relevant LIBOR Advances through the purchase of a Eurodollar deposit bearing
interest at the rate obtained pursuant to the definition of LIBOR Rate in an amount equal to the amount of such LIBOR Advance and having a maturity comparable to the relevant Interest Period; provided, however, that Bank may fund each of its LIBOR
Advances in any manner it sees fit and the foregoing assumptions shall be utilized only for the purposes of calculating amounts payable under this Section 3.6 and under Section 2.5. 
  

 5 

 (e) LIBOR Advances After Default. After the occurrence and during the continuance
of an Event of Default, (i) Borrower may not elect to have an Advance be made or continued as, or converted to, a LIBOR Advance after the expiration of any Interest Period then in effect for such Advance and (ii) subject to the provisions
of Section 3.6(c), any Notice of Conversion/Continuation given by Borrower with respect to a requested conversion/continuation that has not yet occurred shall be deemed to be rescinded by Borrower and be deemed a request to convert or
continue Advances referred to therein as Prime Rate Advances. 
  
 3.7 Additional Requirements/Provisions Regarding LIBOR Advances. 
  
 (a) If for any reason (including voluntary or mandatory prepayment or acceleration), Bank receives all or part of the principal amount of
a LIBOR Advance prior to the last day of the Interest Period for such Advance, Borrower shall immediately notify Borrower’s account officer at Bank and, on demand by Bank, pay Bank the amount (if any) by which (i) the additional interest
which would have been payable on the amount so received had it not been received until the last day of such Interest Period exceeds (ii) the interest which would have been recoverable by Bank by placing the amount so received on deposit in the
certificate of deposit markets, the offshore currency markets, or United States Treasury investment products, as the case may be, for a period starting on the date on which it was so received and ending on the last day of such Interest Period at the
interest rate determined by Bank in its reasonable discretion. Bank’s determination as to such amount shall be conclusive absent manifest error. 
  
 (b) Borrower shall pay Bank, upon demand by Bank, from time to time such amounts as Bank may determine to be necessary to compensate it
for any costs incurred by Bank that Bank determines are attributable to its making or maintaining of any amount receivable by Bank hereunder in respect of any Advances relating thereto (such increases in costs and reductions in amounts receivable
being herein called “Additional Costs”), in each case resulting from any Regulatory Change which: 
  
 (i) changes the basis of taxation of any amounts payable to Bank under this Agreement in respect of any Advances (other than changes which
affect taxes measured by or imposed on the overall net income of Bank by the jurisdiction in which Bank has its principal office); 
  
 (ii) imposes or modifies any reserve, special deposit or similar requirements relating to any extensions of credit or other assets of, or
any deposits with, or other liabilities of Bank (including any Advances or any deposits referred to in the definition of LIBOR); or 
  
 (iii) imposes any other condition affecting this Agreement (or any of such extensions of credit or liabilities). 
  
 Bank will notify Borrower of any event occurring after the Effective Date
which will entitle Bank to compensation pursuant to this Section 3.7 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation. Bank will furnish Borrower with a statement setting forth the
basis and amount of each request by Bank for compensation under this Section 3.7. Determinations and allocations by Bank for purposes of this Section 3.7 of the effect of any Regulatory Change on its costs of maintaining its
obligations to make Advances, of making or maintaining Advances, or on amounts receivable by it in respect of Advances, and of the additional amounts required to compensate Bank in respect of any Additional Costs, shall be conclusive absent manifest
error. 
  
 (c) If Bank shall determine that the
adoption or implementation of any applicable law, rule, regulation, or treaty regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank, or comparable
agency charged with the interpretation or administration thereof, or compliance by Bank (or its applicable lending office) with any respect or directive regarding capital adequacy (whether or not having the force of law) of any such authority,
central bank, or comparable agency, has or would have the effect of reducing the rate of return on capital of Bank or any person or entity controlling Bank (a “Parent”) as a consequence of its obligations hereunder to a level below
that which Bank (or its Parent) could have achieved but for such adoption, change, or compliance (taking into consideration policies with respect to capital adequacy) by an amount deemed by Bank to be material, then from time to time, within 

  

 6 

 
fifteen (15) days after demand by Bank, Borrower shall pay to Bank such additional amount or amounts as will compensate Bank for such reduction. A
statement of Bank claiming compensation under this Section 3.7(c) and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive absent manifest error. 
  
 (d) If, at any time, Bank, in its reasonable discretion,
determines that (i) the amount of LIBOR Advances for periods equal to the corresponding Interest Periods are not available to Bank in the offshore currency interbank markets, or (ii) LIBOR does not accurately reflect the cost to Bank of
lending the LIBOR Advances, then Bank shall promptly give notice thereof to Borrower. Upon the giving of such notice, Bank’s obligation to make additional LIBOR Advances after the date of such notice shall terminate; provided, however, such
Obligation shall not terminate if Bank and Borrower agree in writing to a different interest rate applicable to LIBOR Advances. 
  
 (e) If it shall become unlawful for Bank to continue to fund or maintain any LIBOR Advances, or to perform its obligations hereunder, upon
demand by Bank, Borrower shall prepay the Advances in full with accrued interest thereon and all other amounts payable by Borrower hereunder (including, without limitation, any amount payable in connection with such prepayment pursuant to
Section 3.7(a)) or Borrower may elect to have outstanding Advances converted into or continued as Prime Rate Advances by giving notice (by facsimile or by telephone confirmed in writing) to Bank of such modification on the date on which
Bank gives notice of its determination as described above. Notwithstanding the foregoing, to the extent a determination by Bank as described above relates to a LIBOR Advance then being requested by Borrower pursuant to a Notice of Borrowing or a
Notice of Conversion/Continuation, Borrower shall have the option, subject to the provisions of Section 3.6(c), to (i) rescind such Notice of Borrowing or Notice of Conversion/Continuation by giving notice (by facsimile or by
telephone confirmed in writing) to Bank of such rescission on the date on which Bank gives notice of its determination as described above, or (ii) modify such Notice of Borrowing or Notice of Conversion/Continuation to obtain a Prime Rate
Advance or to have outstanding Advances converted into or continued as Prime Rate Advances by giving notice (by facsimile or by telephone confirmed in writing) to Bank of such modification on the date on which Bank gives notice of its determination
as described above. 
  

	 	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 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 may have superior priority to Bank’s Lien under this Agreement). If Borrower shall acquire a
commercial tort claim, 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. 
  
 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 and at such time as Bank’s obligation to make Credit Extensions has terminated, Bank shall, at Borrower’s sole cost and expense, release its Liens in the Collateral and all rights therein shall revert to Borrower. 

 
 4.2 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, including a notice that any disposition of the Collateral, by either
Borrower or any other Person, shall be deemed to violate the rights of Bank under the Code. Upon termination of Bank’s Lien in the Collateral in accordance with Section 4.1 above, Bank shall promptly file a termination statement
terminating any financing statements filed hereunder and, if Bank does not promptly file such termination statement, Bank hereby authorizes Borrower to file such termination statement. 
  

 7 

	 	5	REPRESENTATIONS AND WARRANTIES. 

  
 Borrower represents and warrants as follows: 
  
 5.1 Due Organization and Authorization. Borrower and each of its Subsidiaries are duly existing and in good standing in their respective
jurisdictions of formation and are qualified and licensed to do business and are in good standing in any jurisdiction in which the conduct of their business or their ownership of property requires that they 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 a completed certificate entitled “Perfection Certificate” signed by
Borrower. 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 address (if different than its chief executive office); (e) Borrower (and each of its predecessors) has
not, in the past five (5) years, changed its state 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 as of the date of the Perfection Certificate. 
  
 The execution, delivery and performance of the Loan Documents have been duly authorized, and do not conflict with Borrower’s organizational
documents, nor constitute an event of default under 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 have a material adverse
effect on Borrower’s business. 
  
 5.2 Collateral.
Borrower has good title to, has 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 deposit accounts other
than the deposit accounts with Bank, the deposit accounts, if any, described in the Perfection Certificate delivered to Bank in connection herewith, or of which Borrower has given Bank notice and taken such actions as are necessary to give Bank a
perfected security interest therein. 
  
 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 Borrower has given Bank notice pursuant to Section 7.2. In the event that Borrower, after the date hereof, intends to store or otherwise deliver any portion of the Collateral to a bailee (other than as provided in the Perfection
Certificate or other as may been previously disclosed to and consented to by Bank), then Borrower will first receive the written consent of Bank and such bailee must execute and deliver a bailee agreement in form and substance satisfactory to Bank
in its sole discretion. 
  
 5.3 Intellectual Property.
Borrower has sufficient rights to use its intellectual property material to its business. To the best of Borrower’s knowledge, no claim has been made that any part of the intellectual property material to Borrower’s business violates the
rights of any third party except to the extent such claim could not reasonably be expected to have a material adverse effect on Borrower’s business. 
  
 5.4 Litigation. There are no actions or proceedings pending or, to the knowledge of the Responsible Officers, threatened in writing by or against
Borrower or any of its Subsidiaries involving more than $500,000. 
  
 5.5 No Material Deviation in Financial Statements. 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.

 5.6 Solvency. The fair salable value of Borrower’s assets (including goodwill minus
disposition costs) exceeds the fair value of its 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. 
  
 5.7 Regulatory Compliance. Borrower is not an “investment
company” or a company “controlled” by an “investment company” under the Investment Company Act. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations T and U of
the Federal Reserve Board of Governors). Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Borrower has not violated any laws, ordinances or rules, 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 in violation of applicable law. Borrower and each of its Subsidiaries have 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 its business as currently conducted. 
  
 5.8 Subsidiaries; Investments. Borrower does not own any stock, partnership interest or other equity securities except for Permitted Investments.

  
 5.9 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. Borrower may defer payment of any contested taxes,
provided that Borrower (a) in good faith contests its obligation to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (b) notifies Bank in writing of the commencement of, and any material
development in, the proceedings, (c) posts bonds or takes any other steps 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. 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 liability of Borrower, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency. 
  
 5.10 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. 
  
 5.11 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 representations, warranties, or other statements were 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).

 6.1 Government Compliance. Borrower shall, and shall cause each of its Subsidiaries to, maintain its legal existence and good standing in its
jurisdiction of formation and each jurisdiction in which the nature of its business requires them to be so qualified, except where the failure to take such action would not reasonably be expected to have a material adverse effect on Borrower’s
and its Subsidiaries’ business or operations, taken as a whole; provided, that (a) the legal existence of any Subsidiary that is not a Guarantor may be terminated or 

  

 9 

 
permitted to lapse, and any qualification of such Subsidiary to do business may be terminated or permitted to lapse, if, in the good faith judgment of
Borrower, such termination or lapse is in the best interests of Borrower and its Subsidiaries, taken as a whole, and (b) Borrower may not permit its qualification to do business in the jurisdiction of its chief executive office to terminate or
lapse; and provided, further, that this Section 6.2 shall not be construed to prohibit any other transaction that is otherwise permitted in Section 7 of this Agreement.

to Bank, on demand, appropriate certificates attesting to such payments, and pay all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms. 
  
 6.4 Insurance. 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 companies, and in amounts that are satisfactory to Bank. All property policies shall have
a lender’s loss payable endorsement showing Bank as an additional lender loss payee and waive subrogation against Bank, and all liability policies shall show, or have endorsements showing, Bank as an additional insured. All policies (or the
loss payable and additional insured endorsements) shall provide that the insurer must give Bank at least twenty (20) days notice before canceling, amending, or declining to renew its policy. At Bank’s request, Borrower shall deliver
certified copies of policies and evidence of all premium payments. Proceeds payable under any policy shall, at Bank’s option, be payable to Bank on account of the Obligations. Notwithstanding the foregoing, so long as no Event of Default has
occurred and is continuing, Borrower shall have the option of applying the proceeds of any casualty policy in the aggregate, toward the replacement or repair of destroyed or damaged property; provided that any such replaced or repaired property
(i) shall be of equal or like value as the replaced or repaired Collateral and (ii) shall be deemed Collateral in which Bank has been granted a first priority security interest, and after the occurrence and during the continuance of an
Event of Default, all proceeds payable under such casualty policy shall, at the option of Bank, be payable to Bank on account of the Obligations. If Borrower fails to obtain insurance as required under this Section 6.4 or to pay any amount or
furnish any required proof of payment to third persons and Bank, Bank may make all or part of such payment or obtain such insurance policies required in this Section 6.4, and take any action under the policies Bank deems prudent.

 8.1 Payment Default. Borrower fails to (a) make any payment of
principal or interest on any Credit Extension on its due date, or (b) pay any other Obligations within three (3) Business Days after such Obligations are due and payable. During the cure period, the failure to cure the payment default is
not an Event of Default (but no Credit Extension will be made during the cure period); 
  
 8.2 Covenant Default. 
  
 (a) Borrower fails or neglects to perform any obligation in Sections 6.2 or 6.6 or violates any covenant in Section 7; or

(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). Grace periods provided under this section shall not apply, among other things, to financial covenants or any other
covenants set forth in subsection (a) above; 
  
 8.3
Material Adverse Change. A Material Adverse Change occurs;

that is due and payable with respect to any Material Indebtedness and such failure continues after the applicable grace or notice period, if any, specified in the agreement or instrument relating thereto, or (b) perform or observe any other
condition or covenant, or any other event shall occur or condition exist under any agreement or instrument relating to any Material Indebtedness, and such failure continues after the applicable grace or notice period, if any, specified in the
agreement or instrument relating thereto and the effect of such failure, event or condition is to cause the holder or holders of such Material Indebtedness to accelerate the maturity of such Material Indebtedness or cause the mandatory repurchase of
any Material Indebtedness; 
  
 8.7 Judgments. A judgment or
judgments for the payment of money in an amount, individually or in the aggregate, of at least $500,000 (not covered by independent third-party insurance) shall be rendered against

 8.9 Subordinated Debt. A default or breach occurs under any agreement between Borrower and any creditor of Borrower that signed a subordination,
intercreditor, or other similar agreement with Bank, or any creditor that has signed such an agreement with Bank breaches any terms of such agreement. 
  

	 	9	BANK’S RIGHTS AND REMEDIES 

  
 9.1 Rights and Remedies. While an Event of Default occurs and continues 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) settle or adjust
disputes and claims directly with Account Debtors for amounts on terms and in any order that Bank considers advisable, notify any Person owing Borrower money of Bank’s security interest in such funds, and verify the amount of such account;

  
 (d) 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; 
  
 (e) 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; 
  
 (f)
ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral in accordance with applicable law, including the Code. 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, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in
completing production of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s
benefit; 
  
 (g) 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; 
  
 (h) demand and receive possession of Borrower’s Books;
and 
  
 (i) 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). 
  

 15 

 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 any security interest regardless of whether an Event of Default has occurred until all 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 have been fully repaid and performed and Bank’s obligation to provide Credit Extensions
terminates. 
  
 9.3 Accounts Verification; Collection.
Whether or not an Event of Default has occurred and is continuing, Bank may (upon prior notice to Borrower if no Event of Default exists) notify any Person owing Borrower money of Bank’s security interest in such funds and verify the amount of
such account. After the occurrence of an Event of Default, any amounts received by Borrower shall be held in trust by Borrower for Bank, and, if requested by Bank, Borrower shall immediately deliver such receipts to Bank in the form received from
the Account Debtor, with proper endorsements for deposit. 
  
 9.4 Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.4 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, 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 applicable rate, 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. 
  
 9.5 Application
of Payments and Proceeds. Unless an Event of Default has occurred and is continuing, Bank shall apply any funds in its possession, whether from Borrower account balances, payments, or proceeds realized as the result of any collection of Accounts
or other disposition of the Collateral, first, to Bank Expenses, including without limitation, the reasonable costs, expenses, liabilities, obligations and attorneys’ fees incurred by Bank in the exercise of its rights under this Agreement;
second, to the interest due upon any of the Obligations; and third, to the principal of the Obligations and any applicable fees and other charges, in such order as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower or
other Persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If an Event of Default has occurred and is continuing, Bank may apply any funds in its possession, whether from Borrower account balances, payments,
proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations in such order as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower or other
Persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If Bank, in its good faith business judgment, 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.

  
 9.6 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.

  
 9.7 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, 

  

 16 

 
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 Bank 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 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. 
  
 9.8 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.

 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 

  

 17 

 
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 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. 
  
 BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY
CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 
  

	 	12	GENERAL PROVISIONS 

  
 12.1 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party. Borrower may not
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,
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. 
  
 12.2 Indemnification. Borrower agrees to indemnify, defend and hold Bank and its directors, officers, employees,
agents, attorneys, or any other Person affiliated with or representing Bank harmless against: (a) all obligations, demands, claims, and liabilities (collectively, “Claims”) asserted by any other party in connection with the
transactions contemplated by the Loan Documents; and (b) all losses or Bank Expenses incurred, or paid by Bank from, following, or arising from transactions between Bank and Borrower (including reasonable attorneys’ fees and expenses),
except for Claims and/or losses directly caused by Bank’s gross negligence or willful misconduct. 
  
 12.3 Limitation of Actions. Any claim or cause of action by Borrower against Bank, its directors, officers, employees, agents, accountants,
attorneys, or any other Person affiliated with or representing Bank based upon, arising from, or relating to this Loan Agreement or any other Loan Document, or any other transaction contemplated hereby or thereby or relating hereto or thereto, or
any other matter, cause or thing whatsoever, occurred, done, omitted or suffered to be done by Bank, its directors, officers, employees, agents, accountants or attorneys, shall be barred unless asserted by Borrower by the commencement of an action
or proceeding in a court of competent jurisdiction by the filing of a complaint within one year after the first act, occurrence or omission upon which such claim or cause of action, or any part thereof, is based, and the service of a summons and
complaint on an officer of Bank, or on any other person authorized to accept service on behalf of Bank, within thirty (30) days thereafter. Borrower agrees that such one-year period is a reasonable and sufficient time for Borrower to
investigate and act upon any such claim or cause of action. The one-year period provided herein shall not be waived, tolled, or extended except by the written consent of Bank in its sole discretion. This provision shall survive any termination of
this Loan Agreement or any other Loan Document. 
  
 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. 
  
 12.6 Amendments in Writing; Integration. All
amendments to this Agreement must be in writing signed by both Bank and Borrower. This Agreement and 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 this Agreement and the Loan Documents merge into this Agreement and the Loan Documents. 
  

 18 

 12.7 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, are an original, and all taken together, constitute one Agreement. 
  
 12.8 Survival. All covenants, representations and warranties made in this Agreement continue in full force until this Agreement has terminated
pursuant to its terms and all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied. The obligation of Borrower in
Section 12.2 to indemnify Bank shall survive until the statute of limitations with respect to such claim or cause of action shall have run. 
  
 12.9 Confidentiality. In handling any confidential information, Bank shall exercise the same degree of care that it exercises for its own
proprietary information, but disclosure of information may be made: (a) to Bank’s Subsidiaries or Affiliates; (b) to prospective transferees or purchasers of any interest in the Credit Extensions (provided, however, Bank shall use
commercially reasonable efforts to obtain such prospective transferee’s or purchaser’s agreement to the terms of this provision); (c) as required by law, regulation, subpoena, or other order; (d) to Bank’s regulators or as
otherwise required in connection with Bank’s examination or audit; and (e) as Bank considers appropriate in exercising remedies under this Agreement. Confidential information does not include information that either: (i) is in the
public domain or in Bank’s possession when disclosed to Bank, or becomes part of the public domain after disclosure to Bank; or (ii) is disclosed to Bank by a third party, if Bank does not know or should not have reasonably known that the
third party is prohibited from disclosing the information. 
  
 12.10 Attorneys’ Fees, Costs and Expenses. In any action or proceeding between Borrower and Bank arising out of or relating to the Loan Documents, the prevailing party shall be entitled to recover its reasonable attorneys’
fees and other costs and expenses incurred, in addition to any other relief to which it may be entitled.
