 Exhibit 10.11 

LOAN AND SECURITY AGREEMENT 

THIS LOAN AND SECURITY AGREEMENT (this “Agreement”) dated as of May 4, 2017 (the “Effective Date”)
between SILICON VALLEY BANK, a California corporation with a loan production office located at 8020 Towers Crescent Drive, Vienna, Virginia 22182 (“Bank”), and TENABLE NETWORK SECURITY, 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 Credit Extensions. 

2.2.1 Revolving Advances. 

(a) Availability. Subject to the terms and conditions of this Agreement, Bank shall make Advances to Borrower not exceeding the
Availability Amount. 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. 

2.2.2 Letters of Credit. 

(a) As part of the Revolving Line, Bank shall issue or have issued Letters of Credit denominated in Dollars or a Foreign Currency for
Borrower’s account. The aggregate Dollar Equivalent amount utilized for the issuance of Letters of Credit shall at all times reduce the amount otherwise available for Advances under the Revolving Line. The aggregate Dollar Equivalent of the
face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) may not exceed Five Million Dollars ($5,000,000). 

(b) If, on the Revolving Line Maturity Date (or the effective date of any termination of this Agreement), there are any outstanding Letters of
Credit, then on such date Borrower shall provide to Bank cash collateral in an amount equal to equal to at least 105% of the aggregate Dollar Equivalent of the face amount of all such Letters of Credit plus all interest, fees, and costs due or
estimated by Bank to become due in connection therewith, to secure all of the Obligations relating to such Letters of Credit. All Letters of Credit shall be in form and substance acceptable to Bank in its sole discretion and shall be subject to the
terms and conditions of Bank’s standard Application and Letter of Credit Agreement (the “Letter of Credit Application”). Borrower agrees to execute any further documentation in connection with the Letters of Credit as Bank may
reasonably request. Borrower further agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guarantied by Bank and opened for Borrower’s account or by Bank’s interpretations of any Letter of Credit
issued by Bank for Borrower’s account, and Borrower understands and agrees that Bank shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrower’s instructions or those contained in
the Letters of Credit or any modifications, amendments, or supplements thereto, except arising solely out of the intentional willful misconduct or bad faith of Bank. 







 (c) The obligation of Borrower to immediately reimburse Bank for drawings made under Letters of
Credit shall be absolute, unconditional, and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, such Letters of Credit, and the Letter of Credit Application. 

(d) Borrower may request that Bank issue a Letter of Credit payable in a Foreign Currency. If a demand for payment is made under any such
Letter of Credit, Bank shall treat such demand as an Advance to Borrower of the Dollar Equivalent of the amount thereof (plus fees and charges in connection therewith such as wire, cable, SWIFT or similar charges). 

(e) To guard against fluctuations in currency exchange rates, upon the issuance of any Letter of Credit payable in a Foreign Currency, Bank
shall create a reserve (the “Letter of Credit Reserve”) under the Revolving Line in an amount equal to ten percent (10%) of the face amount of such Letter of Credit. The amount of the Letter of Credit Reserve may be adjusted by Bank
from time to time to account for fluctuations in the exchange rate. The availability of funds under the Revolving Line shall be reduced by the amount of such Letter of Credit Reserve for as long as such Letter of Credit remains outstanding. 

2.3 Overadvances. If, at any time, the sum of (a) the outstanding principal amount of any
Advances plus (b) the face amount of any outstanding Letters of Credit (including, without duplication, drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve), exceeds the Revolving Line, Borrower shall immediately pay to
Bank in cash the amount of such excess (such excess, the “Overadvance”). Without limiting Borrower’s obligation to repay Bank any Overadvance, Borrower agrees to pay Bank interest on the outstanding amount of any Overadvance,
on demand, at the Default Rate. 
 2.4 Payment of Interest on the Credit Extensions. 

(a) Interest; Payment. 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 (i) for Prime Rate Advances, the Prime Rate plus the Applicable Margin applicable to Prime Rate Advances, and (ii) for LIBOR Advances, the LIBOR Rate plus the Applicable Margin
applicable to LIBOR Advances. 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 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 the Applicable Margin applicable to Prime Rate Advance plus, subject to Section 2.4(e), the Default Rate.
Pursuant to the terms hereof, interest on each Advance shall be paid in arrears on each Interest Payment Date. 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. 

(b) 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. 
 (c) LIBOR Advances. The interest rate applicable
to each LIBOR Advance shall be determined in accordance with Section 3.6(a) hereunder. Subject to Sections 3.5 and 3.6, 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. 
 (d) Computation of Interest. Any interest
hereunder will accrue from day to day and is calculated on the basis of a year of 360 days for the actual number of days elapsed. 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. 







 (e) Default Rate. Upon receipt by Borrower of a notice from Bank following the occurrence
and during the continuance of an Event of Default, Obligations shall bear interest at a rate per annum which is two percentage points (2.0%) above the rate that would otherwise be applicable thereto (the “Default Rate”). Payment or
acceptance of the increased interest provided in this Section 2.4(e) 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. 

2.5 Fees. Borrower shall pay to Bank: 

(a) Commitment Fee. A fully earned, non-refundable commitment fee equal to One Hundred Twenty Five Thousand Dollars ($125,000), on the
Effective Date; and 
 (b) Unused Revolving Line Facility Fee. Payable quarterly in arrears on June 1, 2017, on the first day of each
calendar quarter occurring thereafter prior to the Revolving Line Maturity Date, and on the Revolving Line Maturity Date, a fee (the “Unused Revolving Line Facility Fee”) in an amount equal to one-quarter of one percent (0.25%) per
annum of the average unused portion of the Revolving Line, as determined by Bank. The unused portion of the Revolving Line, for purposes of this calculation, shall be calculated on a calendar year basis and shall equal the difference between
(i) the Revolving Line, and (ii) the average for the period of the daily closing balance of the Revolving Line outstanding; and 

(c) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses for documentation and negotiation of this
Agreement incurred through and after the Effective Date, when due (or, if no stated due date, upon demand by Bank). 
 (d) Fees Fully
Earned. Unless otherwise provided in this Agreement or in a separate writing by Bank, Borrower shall not be entitled to any credit, rebate, or repayment of any fees earned by Bank pursuant to this Agreement notwithstanding any termination of
this Agreement or the suspension or termination of Bank’s obligation to make loans and advances hereunder. Bank may deduct amounts owing by Borrower under the clauses of this Section 2.5 pursuant to the terms of Section 2.6(c). Bank
shall provide Borrower written notice of deductions made from the Designated Deposit Account pursuant to the terms of the clauses of this Section 2.5. 

2.6 Payments; Application of Payments; Debit of Accounts. 

(a) All payments to be made by Borrower under any Loan Document shall be made in immediately available funds in Dollars, without setoff or
counterclaim, before 12:00 p.m. Eastern time on the date when due. Payments of principal and/or interest received after 12:00 p.m. Eastern time are considered received at the opening of business on the next Business Day. When a payment is due on a
day that is not a Business Day, the payment shall be due the next Business Day, and additional fees or interest, as applicable, shall continue to accrue until paid. 

(b) Bank has the exclusive right to determine the order 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 may debit the Designated Deposit Account for principal and interest payments or
any other amounts Borrower owes Bank when due. These debits shall not constitute a set-off. 
 2.7. Withholding. 

(a) 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, and such payment or other sum payable is not
an Excluded Tax, 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 2.7 shall survive the termination of this Agreement. 
 (b) If Bank is entitled to an exemption from
or reduction of withholding tax with respect to payments made under any Loan Document, it shall deliver to Borrower, at the time or times reasonably requested by Borrower, such properly completed and executed documentation reasonably requested by
Borrower as will permit such payments to be made in accordance with such exemption or reduction without withholding or at a reduced rate of withholding, as applicable.

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 precedent to any Credit Extension. Borrower expressly agrees that a Credit Extension made prior to the receipt by Bank of any such item shall not constitute a waiver by Bank of Borrower’s obligation to

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, an Advance
shall be made upon Borrower’s irrevocable written notice delivered to Bank by electronic mail in the form of a Notice of Borrowing executed by an Authorized Signer or without instructions if any Advances is necessary to meet Obligations which
have become due. Such Notice of Borrowing must be received by Bank prior to 12:00 p.m. Eastern time, (i) at least three (3) Business Days prior to the requested Funding Date, in the case of any LIBOR Advance, and (ii) on the requested
Funding Date, in the case of a Prime Rate Advance, specifying: (1) the amount of the Advance; (2) the requested Funding Date; (3) whether the Advance is to be comprised of LIBOR Advances or Prime Rate Advances; and (4) 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) On the Funding Date, Bank shall credit proceeds of an Advance to the Designated Deposit
Account and, subsequently, shall transfer such proceeds 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 applicable Designated Deposit Account. 
 3.5 Conversion and Continuation Elections.

 (a) So long as (i) no Event of 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: 

 

	 	(1)	elect to convert on any Business Day, Prime Rate Advances into LIBOR Advances; 









	 	(2)	elect to continue on any Interest Payment Date any LIBOR Advances maturing on such Interest Payment Date; or 

  

	 	(3)	elect to convert on any Interest Payment Date any LIBOR Advances maturing on such Interest Payment Date into Prime Rate Advances. 


(b) Borrower shall deliver a Notice of Conversion/Continuation by electronic mail to be received by Bank prior to 12:00 p.m. Eastern time
(i) at least 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) on the Conversion Date, if any Advances are to be converted
into Prime Rate Advances, in each case specifying the: 
  

	 	(1)	proposed Conversion Date or Continuation Date; 

  

	 	(2)	aggregate amount of the Advances to be converted or continued; 

  

	 	(3)	nature of the proposed conversion or continuation; and 

  

	 	(4)	if the resulting Advance is to be a LIBOR Advance, the 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 or request to convert a LIBOR Advance into a Prime Rate Advance, Borrower shall be deemed to have elected for any such LIBOR Advances, to convert such LIBOR Advances into Prime Rate Advances. 

(d) Any LIBOR Advances shall, at Bank’s option, convert into Prime Rate Advances in the event that (i) an Event of Default exists,
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 exceeds the Availability Amount. Borrower agrees to pay Bank, upon demand by Bank (or Bank may, at its option, debit the Designated Deposit Account or any other account Borrower maintains
with Bank) any amounts required to compensate Bank for any loss (including loss of anticipated profits), cost, or expense incurred by Bank, as a result of the conversion of LIBOR Advances to Prime Rate Advances pursuant to this Section 3.5(d).

 (e) Notwithstanding anything to the contrary contained herein, Bank shall not be required to purchase 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 LIBOR 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 LIBOR 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. If (i) for any
reason, other than a default by Bank or any failure of Bank to fund LIBOR Advances due to impracticability or illegality under Sections 3.7(c) and 3.7(d) of this Agreement, 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) any complete or partial principal payment or reduction of a LIBOR Advance, or any conversion of any LIBOR Advance, occurs on
a date prior to the last day of an Interest Period applicable to that LIBOR Advance, including due to voluntary or mandatory prepayment or acceleration, then, in each case, Borrower shall compensate Bank, upon written request by Bank, for all losses
and expenses incurred by Bank in an amount equal to the excess, if any, of: 
  

	 	(1)	the amount of interest that would have accrued on the amount (1) not borrowed, converted or continued as provided in clause (i) above, or (2) paid, reduced or converted as provided in clause
(ii) above, for the period from (y) the date of such failure to borrow, convert or continue as provided in clause (i) above, or the date of such payment, reduction or conversion as provided in clause (ii) above, as the case may
be, to (z) in the case of a failure to borrow, convert or continue as provided in clause (i) above, the last day of the Interest Period that would have commenced on the date of such borrowing, conversion or continuing but for such failure,
and in the case of a payment, reduction or conversion prior to the last day of an Interest Period applicable to a LIBOR Advance as provided in clause (ii) above, the last day of such Interest Period, in each case at the applicable rate of
interest or other return for such LIBOR Advance(s) provided for herein (excluding, however, the LIBOR Rate Margin included therein, if any), over 

  

	 	(2)	the interest which would have accrued to Bank on the applicable amount provided in clause (A) above through the purchase of a Eurodollar deposit bearing interest at the rate obtained pursuant to the definition of
LIBOR Rate on the date of such failure to borrow, convert or continue as provided in clause (i) above, or the date of such payment, reduction or conversion as provided in clause (ii) above, as the case may be, for a period equal to the
remaining period of such applicable Interest Period provided in clause (A) above. 

 Bank’s request shall set forth the manner and
method of computing such compensation and such determination as to such compensation shall be conclusive absent manifest error. 
 (d)
Assumptions Concerning Funding of LIBOR Advances. Calculation of all amounts payable to Bank under this Section 3.6 and under Section 3.7 shall be made as though Bank had actually funded each relevant LIBOR Advance 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 3.7. 

(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, at Bank’s option, 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) 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 LIBOR 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 LIBOR Advances (other than changes which affect taxes measured by or imposed on the overall net income of Bank); 

(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 LIBOR 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(a) 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(a). Determinations and allocations by Bank for purposes of this Section 3.7(a) of the effect of any Regulatory Change on its costs of maintaining its obligations to make LIBOR Advances, of making or maintaining LIBOR
Advances, or on amounts receivable by it in respect of LIBOR Advances, and of the additional amounts required to compensate Bank in respect of any Additional Costs, shall be conclusive absent manifest error. 

(b) 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 request 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 ten (10) 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(b) and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive absent manifest error. 

Notwithstanding anything to the contrary in this Section 3.7, Borrower shall not be required to compensate Bank pursuant to this
Section 3.7(b) for any amounts incurred more than nine (9) months prior to the date that Bank notifies Borrower of Bank’s intention to claim compensation therefor; provided that if the circumstances giving rise to such claim have a
retroactive effect, then such nine-month period shall be extended to include the period of such retroactive effect. The obligations of Borrower arising pursuant to this Section 3.7(b) shall survive the Revolving Line Maturity Date, the
termination of this Agreement and the repayment of all Obligations. 
 (c) If, at any time, Bank, in its sole and absolute 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 the LIBOR Advances shall terminate; provided, however, LIBOR Advances shall not terminate if Bank
and Borrower agree in writing to a different interest rate applicable to LIBOR Advances. 







 (d) 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 LIBOR 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 3.6(c)(ii)). 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. 
 (e) If Bank requests compensation under this Section 3.7, or requires Borrower to pay additional amounts to, or
for the account of, Bank, then Bank shall (at the request of Borrower) use reasonable efforts to designate a different lending office for funding or booking its Advances hereunder or to assign its rights and obligations hereunder to another of its
offices, branches or Affiliates, if, in Bank’s judgment, such designation or assignment (a) would eliminate or reduce amounts payable pursuant to this Section 3.6 in the future, and (b) would not subject Bank to any unreimbursed
cost or expense and would not otherwise be disadvantageous to Bank. 
  

	 	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). 
 If this Agreement is terminated, Bank’s Lien in the
Collateral shall continue until the 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 this Section 4.1 (collectively, the “Remaining Obligations”)) are repaid in full in cash. Upon payment in full in cash of the Obligations (other than Remaining 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 Remaining Obligations), 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 at least one hundred five percent (105.0%) of the face amount of all

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). If Borrower shall acquire a commercial tort claim for monetary damages in excess of
One Hundred Thousand Dollars ($100,000.00), 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, 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. 








	 	5.	REPRESENTATIONS AND WARRANTIES 

 Borrower represents and warrants as follows: 

5.1 Due Organization, Authorization; Power and Authority. Each Credit Party is duly existing and in
good standing 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 a completed certificate signed by Borrower, entitled “Perfection
Certificate”. Borrower represents and warrants to Bank that (a) each Credit Party’s exact legal name is that indicated on the Perfection Certificate and on the signature page of each Loan Document to which such Credit Party is a
party; (b) the Credit Party 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 each Credit Party’s organizational
identification number or accurately states that the applicable Credit Party has none; (d) the Perfection Certificate accurately sets forth each Credit Party’s place of business, or, if more than one, its chief executive office as well as
each Credit Party’s mailing address (if different than its chief executive office); (e) no Credit Party (and each of its predecessors) has 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 the Credit Parties 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 not prohibited by one or more specific provisions in this Agreement) in all material respects. If a Credit Party is not now a Registered
Organization but later becomes one, Borrower shall within fifteen (15) days notify Bank of such occurrence and provide Bank with such Credit Party’s organizational identification number. 

The execution, delivery and performance by each Credit Party of the Loan Documents to which it is a party have been duly authorized, and do
not (i) conflict with any of the Credit Party’s organizational documents, (ii) contravene, conflict with, constitute a default under or violate any material Requirement of Law, (iii) contravene, conflict or violate any material
applicable order, writ, judgment, injunction, decree, determination or award of any Governmental Authority by which any Credit Party 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 will be obtained on the Effective Date), 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 a Credit Party is bound. No Credit Party is 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. Each Credit Party has good title to, rights in, and the power to transfer each item
of the Collateral upon which it purports to grant a Lien under the Loan Documents, free and clear of any and all Liens except Permitted Liens. No Credit Party has 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 or as such Credit Party has otherwise notified Bank pursuant to Section 6.6(b), in each case for which
the Credit Parties have taken such actions as are necessary to give Bank a perfected security interest therein, pursuant to the term of Section 6.6. 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 and except for Collateral valued in the aggregate for all locations at less than Four Hundred Fifty Thousand Dollars ($450,000.00) at any time. 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 or Collateral consisting of computer equipment which by its nature is intended to be maintained at locations other than Borrower’s principal places of business
in the ordinary course of business in an aggregate amount for all such locations not to exceed One Million Dollars ($1,000,000.00). 







 All Inventory is in all material respects of good and marketable quality, free from material
defects. 
 Each Credit Party is the sole owner of the Intellectual Property which it owns or purports to own except for
(a) non-exclusive licenses granted to its customers in the ordinary course of business, (b) over-the-counter software that is commercially available to the public, and (c) material Intellectual Property licensed to a Credit Party and
noted on the Perfection Certificate. Each Patent which a Credit Party 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 a Credit Party 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. 

Except as noted on the Perfection Certificate, no Credit Party is a party to, nor is it bound by, any Restricted License. 

5.3 Reserved. 

5.4 Litigation. There is no action or proceeding pending or, to the knowledge of any Responsible
Officer, any non-frivolous threat of action or proceeding in writing by or against any Credit Party involving more than, individually or in the aggregate, Five Hundred Thousand Dollars ($500,000.00). 

5.5 Financial Statements; Financial Condition. All consolidated financial statements for Holdings
and any of its Subsidiaries delivered to Bank fairly present in all material respects Holdings’ consolidated financial condition and Holdings’ consolidated results of operations. There has not been any material deterioration in
Holdings’ consolidated financial condition since the date of the most recent financial statements submitted to Bank. 
 5.6
Solvency. The fair salable value of the Credit Parties’ consolidated assets (including goodwill minus disposition costs) exceeds the fair value of the Credit Parties’ liabilities; the Credit Parties are not
left with unreasonably small capital after the transactions in this Agreement; and the Credit Parties are able to pay its debts (including trade debts) as they mature. 

5.7 Regulatory Compliance. No Credit Party is an “investment company” or a company
“controlled” by an “investment company” under the Investment Company Act of 1940, as amended. No Credit Party is 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). Each Credit Party (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 the properties or assets of any Credit Party have been used by any Credit Party or, to the best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing, treating, or
transporting any hazardous substance other than legally. Each Credit Party has obtained all material consents, approvals and authorizations of, made all material declarations or filings with, and given all material notices to, all Government
Authorities that are necessary to continue its respective business as currently conducted. 
 5.8
Subsidiaries; Investments. The Credit Parties do not own any stock, partnership, or other ownership interest or other equity securities except for Permitted Investments. 

5.9 Tax Returns and Payments; Pension Contributions. Each Credit Party has timely filed all required
tax returns and reports, and each Credit Party has timely paid all foreign, federal, state and local taxes, assessments, deposits and contributions owed by such Credit Party 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 Fifty Thousand Dollars ($50,000.00). 







 To the extent any Credit Party defers payment of any contested taxes in excess of One Hundred
Thousand Dollars ($100,000.00), Borrower shall (i) within thirty (30) days notify Bank in writing of the commencement of, and any material development in, the proceedings, and (ii) post bonds or take 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 the Credit
Parties’ prior tax years which could result in additional taxes becoming due and payable by any Credit Party. Each Credit Party has paid all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in
accordance with their terms, and no Credit Party has 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 any Credit Party, 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 (including Permitted Acquisitions) and not for personal, family, household or agricultural purposes. 

5.11 Full Disclosure. No written representation, warranty or other statement of any Credit Party 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). 

5.12 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.

fails to (a) make any payment of principal on any Credit Extension when due, or (b) make any payment of interest or 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 Revolving Line Maturity Date). During the cure period, the failure to make or pay any payment specified under clause (b) hereunder is not an Event of Default (but no
Credit Extension will be made during the cure period); 







 8.2 Covenant Default. 

(a) Any Credit Party fails or neglects to perform any obligation in Sections 6.2, 6.6, 6.7, 6.10, 6.12, 6.13 or violates any covenant in
Section 7; or 
 (b) Any Credit Party fails or neglects to perform, keep, or observe any other term, provision, condition, covenant or
agreement contained in this Agreement or any Loan Documents, and as to any default (other than those specified in this Section 8) under such other term, provision, condition, covenant or agreement that can be cured, has failed to cure the
default within fifteen (15) Business Days after the occurrence thereof; provided, however, that if the default cannot by its nature be cured within the fifteen (15) Business Days or cannot after diligent attempts by the applicable Credit
Party be cured within such fifteen (15) Business Days period, and such default is likely to be cured within a reasonable time, then such Credit Party shall have an additional period (which shall not in any case exceed forty-five (45) 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 to financial covenants or any other covenants set forth in clause (a) above; 

8.3 Collateral Issues. Bank shall not have or shall cease to have a valid and perfected Lien in any
Collateral purported to be covered by the Loan Documents with the priority required by the relevant Loan Document, in each case for any reason other than the failure of Bank to take any action within its control.

control of a Credit Party (including a Subsidiary) in excess of $250,000, or (ii) a notice of lien or levy is filed against any Credit Party’s assets by any Governmental Authority in an amount greater than $250,000, and the same under
subclauses (i) and (ii) hereof are not, within fifteen (15) days after the occurrence thereof, discharged or stayed (whether through the posting of a bond or otherwise); provided, however, no Credit Extensions shall be made during any
fifteen (15) day cure period; or 
 (b) (i) any material portion of any Credit Party’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; 

8.5 Insolvency. (a) Any Credit Party is unable to pay its debts (including trade debts) as they
become due or any Credit Party fails to be solvent as described under Section 5.6 hereof; (b) any Credit Party begins an Insolvency Proceeding; or (c) an Insolvency Proceeding is begun against any Credit Party and is not dismissed or
stayed within thirty (30) days (but no Credit Extensions shall be made while any of the conditions described in clause (a) exist and/or until any Insolvency Proceeding is dismissed); 

8.6 Other Agreements. There is, under any agreement to which any Credit Party 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 Two Hundred Fifty
Thousand Dollars ($250,000.00); or (b) any breach or default by any Credit Party, the result of which could have a material adverse effect on any Credit Party’s business; 

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 Two Hundred Fifty Thousand Dollars ($250,000.00) (not covered by independent third-party insurance as to which liability has been accepted by such insurance carrier) shall
be rendered against any Credit Party by any Governmental Authority, and the same are not, within forty five (45) 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); 







 8.8 Misrepresentations. Any Credit Party or any Person
acting for any Credit Party makes any representation, warranty, or other statement now or later in this Agreement, any Loan Document or in any writing delivered to Bank or to induce Bank to enter this Agreement or any Loan Document, and such
representation, warranty, or other statement is incorrect in any material respect when made; 
 8.9
Subordinated Debt. The Obligations shall for any reason not be senior (in lien and rights to payment) to any Subordinated Debt or shall not have the lien or payment priority contemplated by the applicable subordination or intercreditor
agreement; 
 8.10 Guaranty. (a) Any Guaranty terminates or ceases for any reason to be in
full force and effect; (b) any Guarantor does not perform any obligation or covenant under any Guaranty; (c) the liquidation, winding up, or termination of existence of any Guarantor; or (d) a material impairment in the perfection or

8.11 Governmental Approvals. Any material 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 reasonably be expected to 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 would (i) cause, or could reasonably be expected to cause, a material adverse effect on Borrower’s business, or (ii) adversely affect the legal qualifications of Borrower or any other Credit Party to hold such material
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 other Credit Party to hold
any material 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) demand that Borrower (i) deposit cash with Bank in an
amount equal to at least 105% of the aggregate face amount of all Letters of Credit remaining undrawn (plus 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; 
 (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 any Credit
Party it holds, or (ii) any amount held by Bank owing to or for the credit or the account of any Credit Party; 
 (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, each Credit Party’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, each Credit Party’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 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 (other than Remaining Obligations)
and Bank’s obligation to provide Credit Extensions terminates. 
 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 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, New York 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 New
York, New York; 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 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. 
 This Section 11 shall survive
the termination of this Agreement. 
  

	 	12.	GENERAL PROVISIONS 

 12.1 Termination Prior
to Revolving Line Maturity Date; 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 have been satisfied (other than
Remaining Obligations). So long as Borrower has satisfied the Obligations (other than Remaining Obligations), this Agreement may be terminated prior to the Revolving Line Maturity Date by Borrower, effective three (3) Business Days after
written notice of termination is given to Bank or such shorter period as Bank shall agree). 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, with the prior consent of Borrower (not to be unreasonably withheld or delayed) so long as there is no continuing Event of Default, 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. Bank shall maintain a register of the names and addresses of each Person and the commitments of, and principal amounts (and stated
interest) of the loans owing to, such Person pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and Borrower shall treat each Person whose name is
recorded in the Register pursuant to the terms hereof as Bank hereunder for all purposes of this Agreement. The Register shall be available for inspection by Borrower and any lender, at any reasonable time and from time to time upon reasonable prior
notice. 
 12.3 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 (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 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 the Loan Documents (including reasonable attorneys’ fees and expenses), except for Claims and/or losses directly caused by such Indemnified Person’s gross
negligence or willful misconduct or result from a claim brought by Holdings or any of its Subsidiaries against an Indemnified Person for breach in bad faith of such person’s obligations hereunder or under any other Loan Document. 

This Section 12.3 shall survive until all statutes of limitation with respect to the Claims, losses, and expenses for which indemnity is
given shall have run. 
 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 Correction of Loan
Documents. Bank may correct patent errors and fill in any blanks 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. 

12.8 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, is an original, and all taken together, constitute one Agreement. 

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 (such Subsidiaries and Affiliates, together with Bank, collectively, “Bank
Entities”); (b) to prospective transferees or purchasers of any interest in the Credit Extensions (provided, however, Bank shall use its best efforts to obtain any prospective transferee’s or purchaser’s agreement to the terms of
this provision); (c) as required by law, regulation, subpoena, or other order; provided Bank shall make reasonable efforts to notify Borrower of any such required disclosure; (d) to Bank’s regulators or as otherwise required in connection
with Bank’s examination or audit; (e) as Bank considers appropriate in exercising remedies under the Loan Documents; and (f) to third-party service providers of Bank so long as such service providers have executed a confidentiality
agreement with Bank with terms no less restrictive than those contained herein. 







 
Confidential information does not include information that is either: (i) in the public domain or in Bank’s possession when disclosed to Bank, or becomes part of the public domain
(other than as a result of its disclosure by Bank in violation of this Agreement) after disclosure to Bank; or (ii) disclosed to Bank by a third party, if Bank does not know that the third party is prohibited from disclosing the information.

 Bank Entities may use anonymous forms of confidential information for aggregate datasets, for analyses or reporting, and for any other
uses not expressly prohibited in writing by Borrower. The provisions of the immediately preceding sentence shall survive termination of this Agreement. 

12.10 Right of Set Off. Borrower hereby grants to Bank, a lien, security interest and right of set off as security for
all Obligations to Bank, whether now existing or hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Bank or any entity under the control of Bank
(including a Bank subsidiary) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Bank may set off the same or any part thereof and apply the same to any
liability or obligation of Borrower even though unmatured and regardless of the adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL
WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. 

12.11 Electronic Execution of Documents. The words “execution,” “signed,” “signature” and
words of like import in any Loan Document shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity and enforceability as a manually executed signature or
the use of a paper-based recordkeeping systems, as the case may be, to the extent and as provided for in any applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act. 

12.12 Captions. The headings used in this Agreement are for convenience only and shall not affect the interpretation of
this Agreement. 
 12.13 Construction of Agreement. The parties mutually acknowledge that they and their attorneys have
participated in the preparation and negotiation of this Agreement. In cases of uncertainty this Agreement shall be construed without regard to which of the parties caused the uncertainty to exist. 

12.14 Relationship. The relationship of the parties to this Agreement is determined solely by the provisions of this
Agreement. The parties do not intend to create any agency, partnership, joint venture, trust, fiduciary or other relationship with duties or incidents different from those of parties to an arm’s-length contract. 

12.15 Third Parties. Nothing in this Agreement, whether express or implied, is intended to: (a) confer any benefits,
rights or remedies under or by reason of this Agreement on any persons other than the express parties to it and their respective permitted successors and assigns; (b) relieve or discharge the obligation or liability of any person not an express
party to this Agreement; or (c) give any person not an express party to this Agreement any right of subrogation or action against any party to this Agreement.
