or delivery of the Voting Agreements, (iii) the public or other announcement of the Merger Agreement, the Voting Agreements or the transactions contemplated thereby, (iv) the consummation of the Merger or (v) the consummation of any
other transaction contemplated by the Merger Agreement or the Voting Agreements.”

 “or (iv) immediately prior to the Effective Time (as defined in
the Merger Agreement) (the earliest of (i), (ii), (iii) and (iv) being herein referred to as the “Expiration Date”).” 
  
 Section 4. Termination of Merger Agreement. If for any reason the Merger Agreement is terminated, then this Second Amendment shall be of no further
force and effect and the Rights Agreement shall remain exactly the same as it existed immediately prior to the effectiveness of this Second Amendment. 
  
 Section 5. Effectiveness. This Second Amendment shall be deemed effective as of, and immediately prior to, the execution and delivery of the Merger

provision to any person or circumstance, shall be held by a court of competent jurisdiction or other authority to be invalid, illegal or unenforceable, the remainder of the provisions of this Second Amendment shall remain in full force and effect
and shall in no way be affected, impaired or invalidated.

the same instrument. 
  
 Section 8. Governing Law. This
Second Amendment shall be deemed to be a contract made under the laws of the State of Georgia and for all purposes shall be governed by and construed in accordance with the laws of such state applicable to contracts made and to be performed entirely

	 	(i)	85% of the amount of Eligible Accounts (net of the Deferred Revenue Reserve), less the amount, if any, of the Dilution Reserve, and 

  

	 	(ii)	an amount equal to Borrowers’ Collections with respect to Accounts for the immediately preceding 60 day period, minus 

  

	 	(y)	the sum of (i) the Bank Products Reserve, (ii) the Availability Block, and (iii) the aggregate amount of reserves, if any, established by Agent under
Section 2. 1(b). 

  
 (b) Anything to the contrary in this Section 2.1 notwithstanding, Agent shall have the right to establish reserves in such amounts, and with respect to such matters, as Agent in its Permitted Discretion shall deem necessary or
appropriate, against the Borrowing Base, including reserves with respect to (i) sums that Companies are required to pay (such as taxes, assessments, insurance premiums, or, in the case of leased assets, rents or other amounts payable under such
leases) and has failed to pay under any Section of this Agreement or any other Loan Document, and (ii) amounts owing by Companies to any Person to the extent secured by a Lien on, or trust over, any of the Collateral (other than any existing
Permitted Lien set forth on Schedule P-1 which is specifically identified thereon as entitled to have priority over the Agent’s Liens), which Lien or trust, in the Permitted Discretion of Agent likely would have a priority superior to
the Agent’s Liens (such as Liens or trusts in favor of landlords, warehousemen, carriers, mechanics, materialmen, laborers, or 

  

 -25- 

 
suppliers, or Liens or trusts for ad valorem, excise, sales, or other taxes where given priority under applicable law) in and to such item of the
Collateral. 
  
 (c) The Lenders with Revolver
Commitments shall have no obligation to make additional Advances hereunder to the extent such additional Advances would cause the Revolver Usage to exceed the Maximum Revolver Amount. 
  
 (d) Amounts borrowed pursuant to this Section may be repaid and, subject to the terms and conditions of this
Agreement, reborrowed at any time during the term of this Agreement. 
  

	 	2.2.	Intentionally Omitted. 

  

	 	2.3.	Borrowing Procedures and Settlements. 

  
 (a) Procedure for Borrowing. Each Borrowing shall be made by an irrevocable written request by an Authorized Person delivered to
Agent (which notice must be received by Agent no later than 10:00 a.m. (California time) on the Business Day prior to the date that is the requested Funding Date in the case of a request for an Advance specifying (i) the amount of such
Borrowing, and (ii) the requested Funding Date, which shall be a Business Day; provided, however, that in the case of a request for Swing Loan in an amount of $5,000,000, or less, such notice will be timely received if it is
received by Agent no later than 10:00 a.m. (California time) on the Business Day that is the requested Funding Date) specifying (i) the amount of such Borrowing, and (ii) the requested Funding Date, which shall be a Business Day. At
Agent’s election, in lieu of delivering the above-described written request, any Authorized Person may give Agent telephonic notice of such request by the required time, with such telephonic notice to be confirmed in writing within 24 hours of
the giving of such notice. 
  
 (b)
Agent’s Election. Promptly after receipt of a request for a Borrowing pursuant to Section 2.3(a), Agent shall elect, in its discretion, (i) to have the terms of Section 2.3(c) apply to such requested Borrowing, or
(ii) if the Borrowing is for an Advance, to request Swing Lender to make a Swing Loan pursuant to the terms of Section 2.3(d) in the amount of the requested Borrowing; provided, however, that if Swing Lender declines
in its sole discretion to make a Swing Loan pursuant to Section 2.3(d), Agent shall elect to have the terms of Section 2.3(c) apply to such requested Borrowing. 
  
 (c) Making of Advances. 
  
 (i) In the event that Agent shall elect to have the terms of this Section 2.3(c) apply to a
requested Borrowing as described in Section 2.3(b), then promptly after receipt of a request for a Borrowing pursuant to Section 2.3(a), Agent shall notify the Lenders, not later than 1:00 p.m. (California time) on the
Business Day immediately preceding the Funding Date applicable thereto, by telecopy, telephone, or other similar form of transmission, of the requested Borrowing. Each Lender shall make the amount of such Lender’s Pro Rata Share of the
requested 

  

 -26- 

 
Borrowing available to Agent in immediately available funds, to Agent’s Account, not later than 10:00 a.m. (California time) on the Funding Date
applicable thereto. After Agent’s receipt of the proceeds of such Advances, upon satisfaction of the applicable conditions precedent set forth in Section 3 hereof, Agent shall make the proceeds thereof available to Administrative
Borrower on the applicable Funding Date by transferring immediately available funds equal to such proceeds received by Agent to Administrative Borrower’s Designated Account; provided, however, that, subject to the provisions of
Section 2.3(i), Agent shall not request any Lender to make, and no Lender shall have the obligation to make, any Advance if Agent shall have actual knowledge that (1) one or more of the applicable conditions precedent set forth in
Section 3 will not be satisfied on the requested Funding Date for the applicable Borrowing unless such condition has been waived, or (2) the requested Borrowing would exceed the Availability on such Funding Date. 
  
 (ii) Unless Agent receives notice from a Lender on or prior
to the Closing Date or, with respect to any Borrowing after the Closing Date, at least 1 Business Day prior to the date of such Borrowing, that such Lender will not make available as and when required hereunder to Agent for the account of Borrowers
the amount of that Lender’s Pro Rata Share of the Borrowing, Agent may assume that each Lender has made or will make such amount available to Agent in immediately available funds on the Funding Date and Agent may (but shall not be so required),
in reliance upon such assumption, make available to Borrowers on such date a corresponding amount. If and to the extent any Lender shall not have made its full amount available to Agent in immediately available funds and Agent in such circumstances
has made available to Borrowers such amount, that Lender shall on the Business Day following such Funding Date make such amount available to Agent, together with interest at the Defaulting Lender Rate for each day during such period. A notice
submitted by Agent to any Lender with respect to amounts owing under this subsection shall be conclusive, absent manifest error. If such amount is so made available, such payment to Agent shall constitute such Lender’s Advance on the date of
Borrowing for all purposes of this Agreement. If such amount is not made available to Agent on the Business Day following the Funding Date, Agent will notify Administrative Borrower of such failure to fund and, upon demand by Agent, Borrowers shall
pay such amount to Agent for Agent’s account, together with interest thereon for each day elapsed since the date of such Borrowing, at a rate per annum equal to the interest rate applicable at the time to the Advances composing such Borrowing.
The failure of any Lender to make any Advance on any Funding Date shall not relieve any other Lender of any obligation hereunder to make an Advance on such Funding Date, but no Lender shall be responsible for the failure of any other Lender to make
the Advance to be made by such other Lender on any Funding Date. 
  
 (iii) Agent shall not be obligated to transfer to a Defaulting Lender any payments made by Borrowers to Agent for the Defaulting Lender’s benefit, and, in the absence of such transfer to the Defaulting Lender,
Agent shall transfer any such payments to each other non-Defaulting Lender member of the Lender Group ratably 

  

 -27- 

 
in accordance with their Commitments (but only to the extent that such Defaulting Lender’s Advance was funded by the other members of the Lender Group)
or, if so directed by Administrative Borrower and if no Default or Event of Default had occurred and is continuing (and to the extent such Defaulting Lender’s Advance was not funded by the Lender Group), retain same to be re-advanced to
Borrowers as if such Defaulting Lender had made Advances to Borrowers. Subject to the foregoing, Agent may hold and, in its Permitted Discretion, re-lend to Borrowers for the account of such Defaulting Lender the amount of all such payments received
and retained by it for the account of such Defaulting Lender. Solely for the purposes of voting or consenting to matters with respect to the Loan Documents, such Defaulting Lender shall be deemed not to be a “Lender” and such Lender’s
Commitment shall be deemed to be zero. This Section shall remain effective with respect to such Lender until (x) the Obligations under this Agreement shall have been declared or shall have become immediately due and payable, (y) the
non-Defaulting Lenders, Agent, and Administrative Borrower shall have waived such Defaulting Lender’s default in writing, or (z) the Defaulting Lender makes its Pro Rata Share of the applicable Advance and pays to Agent all amounts owing
by Defaulting Lender in respect thereof. The operation of this Section shall not be construed to increase or otherwise affect the Commitment of any Lender, to relieve or excuse the performance by such Defaulting Lender or any other Lender of its
duties and obligations hereunder, or to relieve or excuse the performance by Borrowers of their duties and obligations hereunder to Agent or to the Lenders other than such Defaulting Lender. Any such failure to fund by any Defaulting Lender shall
constitute a material breach by such Defaulting Lender of this Agreement and shall entitle Administrative Borrower at its option, upon written notice to Agent, to arrange for a substitute Lender to assume the Commitment of such Defaulting Lender,
such substitute Lender to be acceptable to Agent and Borrowers. In connection with the arrangement of such a substitute Lender, the Defaulting Lender shall have no right to refuse to be replaced hereunder, and agrees to execute and deliver a
completed form of Assignment and Acceptance Agreement in favor of the substitute Lender (and agrees that it shall be deemed to have executed and delivered such document if it fails to do so) subject only to being repaid its share of the outstanding
Obligations (other than Bank Product Obligations) (including an assumption of its Pro Rata Share of the Risk Participation Liability) without any premium or penalty of any kind whatsoever; provided further, however, that any
such assumption of the Commitment of such Defaulting Lender shall not be deemed to constitute a waiver of any of the Lender Groups’ or Borrowers’ rights or remedies against any such Defaulting Lender arising out of or in relation to such
failure to fund. 
  
 (d) Making of Swing
Loans. 
  
 (i) In the event Agent shall
elect, with the consent of Swing Lender, as a Lender, to have the terms of this Section 2.3(d) apply to a requested Borrowing as described in Section 2.3 (b), Swing Lender as a Lender shall make such Advance in the amount of
such Borrowing (any such Advance made solely by Swing 

  

 -28- 

 
Lender as a Lender pursuant to this Section 2.3(d) being referred to as a “Swing Loan” and such Advances being referred to
collectively as “Swing Loans”) available to Borrowers on the Funding Date applicable thereto by transferring immediately available funds to Administrative Borrower’s Designated Account. Each Swing Loan is an Advance hereunder
and shall be subject to all the terms and conditions applicable to other Advances, except that no such Swing Loan shall be eligible for the LIBOR Option and all payments on any Swing Loan shall be payable to Swing Lender as a Lender solely for its
own account (and for the account of the holder of any participation interest with respect to such Swing Loan). Subject to the provisions of Section 2.3 (i), Agent shall not request Swing Lender as a Lender to make, and Swing Lender as a
Lender shall not make, any Swing Loan if Agent has actual knowledge that (i) one or more of the applicable conditions precedent set forth in Section 3 will not be satisfied on the requested Funding Date for the applicable Borrowing
unless such condition has been waived, or (ii) the requested Borrowing would exceed the Availability on such Funding Date. Swing Lender as a Lender shall not otherwise be required to determine whether the applicable conditions precedent set
forth in Section 3 have been satisfied on the Funding Date applicable thereto prior to making, in its sole discretion, any Swing Loan. 
  
 (ii) The Swing Loans shall be secured by the Agent’s Liens, shall constitute Advances and Obligations hereunder, and shall bear
interest at the rate applicable from time to time to Advances that are Base Rate Loans. 
  
 (e) Agent Advances. 
  
 (i) Agent hereby is authorized by Borrowers and the Lenders, from time to time in Agent’s sole discretion, (1) after the
occurrence and during the continuance of a Default or an Event of Default, or (2) at any time that any of the other applicable conditions precedent set forth in Section 3 have not been satisfied, to make Advances to Borrowers on
behalf of the Lenders that Agent, in its Permitted Discretion deems necessary or desirable (A) to preserve or protect the Collateral, or any portion thereof, (B) to enhance the likelihood of repayment of the Obligations (other than the
Bank Product Obligations), or (C) to pay any other amount chargeable to Borrowers pursuant to the terms of this Agreement, including Lender Group Expenses and the costs, fees, and expenses described in Section 10 (any of the
Advances described in this Section 2.3(e) shall be referred to as “Agent Advances”). Each Agent Advance is an Advance hereunder and shall be subject to all the terms and conditions applicable to other Advances, except
that no such Agent Advance shall be eligible for the LIBOR Option and all payments thereon shall be payable to Agent solely for its own account (and for the account of the holder of any participation interest with respect to such Agent Advance).

  
 (ii) The Agent Advances shall be repayable on
demand and secured by the Agent’s Liens granted to Agent under the Loan Documents, shall constitute Advances and Obligations hereunder, and shall bear interest at the rate applicable from time to time to Advances that are Base Rate Loans.

  

 -29- 

 (f) Settlement. It is agreed that each Lender’s funded portion of the
Advances is intended by the Lenders to equal, at all times, such Lender’s Pro Rata Share of the outstanding Advances. Such agreement notwithstanding, Agent, Swing Lender, and the other Lenders agree (which agreement shall not be for the benefit
of or enforceable by Borrowers) that in order to facilitate the administration of this Agreement and the other Loan Documents, settlement among them as to the Advances, the Swing Loans, and the Agent Advances shall take place on a periodic basis in
accordance with the following provisions: 
  
 (i)
Agent shall request settlement (“Settlement”) with the Lenders on a weekly basis, or on a more frequent basis if so determined by Agent, (1) on behalf of Swing Lender, with respect to each outstanding Swing Loan, (2) for
itself, with respect to each Agent Advance, and (3) with respect to Collections received, as to each by notifying the Lenders by telecopy, telephone, or other similar form of transmission, of such requested Settlement, no later than 2:00 p.m.
(California time) on the Business Day immediately prior to the date of such requested Settlement (the date of such requested Settlement being the “Settlement Date”). Such notice of a Settlement Date shall include a summary statement
of the amount of outstanding Advances, Swing Loans, and Agent Advances for the period since the prior Settlement Date. Subject to the terms and conditions contained herein (including Section 2.3(c)(iii)): (y) if a Lender’s balance
of the Advances, Swing Loans, and Agent Advances exceeds such Lender’s Pro Rata Share of the Advances, Swing Loans, and Agent Advances as of a Settlement Date, then Agent shall, by no later than 12:00 p.m. (California time) on the Settlement
Date, transfer in immediately available funds to the account of such Lender as such Lender may designate, an amount such that each such Lender shall, upon receipt of such amount, have as of the Settlement Date, its Pro Rata Share of the Advances,
Swing Loans, and Agent Advances, and (z) if a Lender’s balance of the Advances, Swing Loans, and Agent Advances is less than such Lender’s Pro Rata Share of the Advances, Swing Loans, and Agent Advances as of a Settlement Date, such
Lender shall no later than 12:00 p.m. (California time) on the Settlement Date transfer in immediately available funds to the Agent’s Account, an amount such that each such Lender shall, upon transfer of such amount, have as of the Settlement
Date, its Pro Rata Share of the Advances, Swing Loans, and Agent Advances. Such amounts made available to Agent under clause (z) of the immediately preceding sentence shall be applied against the amounts of the applicable Swing Loan or Agent
Advance and, together with the portion of such Swing Loan or Agent Advance representing Swing Lender’s Pro Rata Share thereof, shall constitute Advances of such Lenders. If any such amount is not made available to Agent by any Lender on the
Settlement Date applicable thereto to the extent required by the terms hereof, Agent shall be entitled to recover for its account such amount on demand from such Lender together with interest thereon at the Defaulting Lender Rate. 
  
 (ii) In determining whether a Lender’s balance of the
Advances, Swing Loans, and Agent Advances is less than, equal to, or greater than such Lender’s Pro Rata Share of the Advances, Swing Loans, and Agent Advances as of a 

  

 -30- 

 
Settlement Date, Agent shall, as part of the relevant Settlement, apply to such balance the portion of payments actually received in good funds by Agent with
respect to principal, interest, fees payable by Borrowers and allocable to the Lenders hereunder, and proceeds of Collateral. To the extent that a net amount is owed to any such Lender after such application, such net amount shall be distributed by
Agent to that Lender as part of such next Settlement. 
  
 (iii) Between Settlement Dates, Agent, to the extent no Agent Advances or Swing Loans are outstanding, may pay over to Swing Lender any payments received by Agent, that in accordance with the terms of this Agreement would be applied to the
reduction of the Advances, for application to Swing Lender’s Pro Rata Share of the Advances. If, as of any Settlement Date, Collections received since the then immediately preceding Settlement Date have been applied to Swing Lender’s Pro
Rata Share of the Advances other than to Swing Loans, as provided for in the previous sentence, Swing Lender shall pay to Agent for the accounts of the Lenders, and Agent shall pay to the Lenders, to be applied to the outstanding Advances of such
Lenders, an amount such that each Lender shall, upon receipt of such amount, have, as of such Settlement Date, its Pro Rata Share of the Advances. During the period between Settlement Dates, Swing Lender with respect to Swing Loans, Agent with
respect to Agent Advances, and each Lender (subject to the effect of letter agreements between Agent and individual Lenders) with respect to the Advances other than Swing Loans and Agent Advances, shall be entitled to interest at the applicable rate
or rates payable under this Agreement on the daily amount of funds employed by Swing Lender, Agent, or the Lenders, as applicable. 
  
 (g) Notation. Agent shall record on its books the principal amount of the Advances owing to each Lender, including the Swing Loans
owing to Swing Lender, and Agent Advances owing to Agent, and the interests therein of each Lender, from time to time. In addition, each Lender is authorized, at such Lender’s option, to note the date and amount of each payment or prepayment of
principal of such Lender’s Advances in its books and records, including computer records, such books and records constituting conclusive evidence, absent manifest error, of the accuracy of the information contained therein. 
  
 (h) Lenders’ Failure to Perform. All Advances
(other than Swing Loans and Agent Advances) shall be made by the Lenders contemporaneously and in accordance with their Pro Rata Shares. It is understood that (i) no Lender shall be responsible for any failure by any other Lender to perform its
obligation to make any Advance (or other extension of credit) hereunder, nor shall any Commitment of any Lender be increased or decreased as a result of any failure by any other Lender to perform its obligations hereunder, and (ii) no failure
by any Lender to perform its obligations hereunder shall excuse any other Lender from its obligations hereunder. 
  
 (i) Optional Overadvances. Any contrary provision of this Agreement notwithstanding, the Lenders hereby authorize Agent or Swing
Lender, as applicable, and Agent or Swing Lender, as applicable, may, but is not obligated to, knowingly and intentionally, continue to make Advances (including Swing Loans) to Borrowers 

  

 -31- 

 
notwithstanding that an Overadvance exists or thereby would be created, so long as (i) after giving effect to such Advances (including a Swing Loan),
the Revolver Usage does not exceed the Borrowing Base by more than $2,500,000, (ii) after giving effect to such Advances (including a Swing Loan) the outstanding Revolver Usage (except for and excluding amounts charged to the Loan Account for
interest, fees, or Lender Group Expenses) does not exceed the Maximum Revolver Amount, and (iii) at the time of the making of any such Advance (including a Swing Loan), Agent does not believe, in good faith, that the Overadvance created by such
Advance will be outstanding for more than 90 days. The foregoing provisions are for the exclusive benefit of Agent, Swing Lender, and the Lenders and are not intended to benefit Borrowers in any way. The Advances and Swing Loans, as applicable, that
are made pursuant to this Section 2.3(i) shall be subject to the same terms and conditions as any other Advance or Swing Loan, as applicable, except that they shall not be eligible for the LIBOR Option and the rate of interest applicable
thereto shall be the rate applicable to Advances that are Base Rate Loans under Section 2.6(c) hereof without regard to the presence or absence of a Default or Event of Default. 
  
 (i) In the event Agent obtains actual knowledge that the
Revolver Usage exceeds the amounts permitted by the preceding paragraph, regardless of the amount of, or reason for, such excess, Agent shall notify Lenders as soon as practicable (and prior to making any (or any additional) intentional Overadvances
(except for and excluding amounts charged to the Loan Account for interest, fees, or Lender Group Expenses) unless Agent determines that prior notice would result in imminent harm to the Collateral or its value), and the Lenders with Revolver
Commitments thereupon shall, together with Agent, jointly determine the terms of arrangements that shall be implemented with Borrowers and intended to reduce, within a reasonable time, the outstanding principal amount of the Advances to Borrowers to
an amount permitted by the preceding paragraph. In the event Agent or any Lender disagrees over the terms of reduction or repayment of any Overadvance, the terms of reduction or repayment thereof shall be implemented according to the determination
of the Required Lenders. 
  
 (ii) Each Lender
with a Revolver Commitment shall be obligated to settle with Agent as provided in Section 2.3(f) for the amount of such Lender’s Pro Rata Share of any unintentional Overadvances by Agent reported to such Lender, any intentional
Overadvances made as permitted under this Section 2.3(i), and any Overadvances resulting from the charging to the Loan Account of interest, fees, or Lender Group Expenses. 
  

	 	2.4.	Payments. 

  
 (a) Payments by Borrowers. 
  
 (i) Except as otherwise expressly provided herein, all payments by Borrowers shall be made to Agent’s Account for the account of the
Lender Group and shall be made in immediately available funds, no later than 11:00 a.m. (California time) on the date specified herein. Any payment received by Agent later than 11:00 

  

 -32- 

 
a.m. (California time), shall be deemed to have been received on the following Business Day and any applicable interest or fee shall continue to accrue until
such following Business Day. 
  
 (ii) Unless
Agent receives notice from Administrative Borrower prior to the date on which any payment is due to the Lenders that Borrowers will not make such payment in full as and when required, Agent may assume that Borrowers have made (or will make) such
payment in full to Agent on such date in immediately available funds and Agent may (but shall not be so required), in reliance upon such assumption, distribute to each Lender on such due date an amount equal to the amount then due such Lender. If
and to the extent Borrowers do not make such payment in full to Agent on the date when due, each Lender severally shall repay to Agent on demand such amount distributed to such Lender, together with interest thereon at the Defaulting Lender Rate for
each day from the date such amount is distributed to such Lender until the date repaid. 
  
 (b) Apportionment and Application. 
  
 (i) Except as otherwise provided with respect to Defaulting Lenders and except as otherwise provided in the Loan Documents (including
letter agreements between Agent and individual Lenders), aggregate principal and interest payments shall be apportioned ratably among the Lenders (according to the unpaid principal balance of the Obligations to which such payments relate held by
each Lender) and payments of fees and expenses (other than fees or expenses that are for Agent’s separate account, after giving effect to any letter agreements between Agent and individual Lenders) shall be apportioned ratably among the Lenders
having a Pro Rata Share of the type of Commitment or Obligation to which a particular fee relates. All payments shall be remitted to Agent and all such payments (other than payments received while no Default or Event of Default has occurred and is
continuing and which relate to the payment of principal or interest of specific Obligations or which relate to the payment of specific fees), and all proceeds of Accounts or other Collateral received by Agent, shall be applied as follows:

  
 (A) first, to pay any Lender Group
Expenses then due to Agent under the Loan Documents, until paid in full, 
  
 (B) second, to pay any Lender Group Expenses then due to the Lenders under the Loan Documents, on a ratable basis, until paid in full, 
  
 (C) third, to pay any fees then due to Agent (for its separate accounts, after giving effect to any
letter agreements between Agent and the individual Lenders) under the Loan Documents until paid in full, 
  
 (D) fourth, to pay any fees then due to any or all of the Lenders (after giving effect to any letter agreements between Agent and
individual Lenders) under the Loan Documents, on a ratable basis, until paid in full, 
  

 -33- 

 (E) fifth, to pay interest due in respect of all Agent Advances, until paid in
full, 
  
 (F) sixth, ratably to pay
interest due in respect of the Advances (other than Agent Advances) and the Swing Loans until paid in full, 
  
 (G) seventh, to pay the principal of all Agent Advances until paid in full, 
  
 (H) eighth, to pay the principal of all Swing Loans
until paid in full, 
  
 (I) ninth, so
long as no Event of Default has occurred and is continuing, and at Agent’s election (which election Agent agrees will not be made if an Overadvance would be created thereby), to pay amounts then due and owing by Administrative Borrower or its
Subsidiaries in respect of Bank Products, until paid in full, 
  
 (J) tenth, so long as no Event of Default has occurred and is continuing, to pay the principal of all Advances until paid in full, 
  
 (K) eleventh, if an Event of Default has occurred and is continuing, ratably (i) to pay the
principal of all Advances until paid in full, and (ii) to Agent, to be held by Agent, for the benefit of Wells Fargo or its Affiliates, as applicable, as cash collateral in an amount up to the amount of the Bank Products Reserve established
prior to the occurrence of, and not in contemplation of, the subject Event of Default until Administrative Borrower’s and its Subsidiaries’ obligations in respect of the then extant Bank Products have been paid in full or the cash
collateral amount has been exhausted, 
  
 (L)
twelfth, if an Event of Default has occurred and is continuing, to Agent, to be held by Agent, for the ratable benefit of Issuing Lender and those Lenders having a Revolver Commitment, as cash collateral in an amount up to 105% of the then
extant Letter of Credit Usage until paid in full, 
  
 (M) thirteenth, to pay any other Obligations (including Bank Product Obligations) until paid in full, and 
  
 (N) fourteenth, to Borrowers (to be wired to the Designated Account) or such other Person entitled thereto under applicable law.

  

 -34- 

 (ii) Agent promptly shall distribute to each Lender, pursuant to the applicable wire
instructions received from each Lender in writing, such funds as it may be entitled to receive, subject to a Settlement delay as provided in Section 2.3(h). 
  
 (iii) In each instance, so long as no Event of Default has occurred and is continuing, Section 2A(b)
shall not be deemed to apply to any payment by Borrowers specified by Borrowers to be for the payment of specific Obligations then due and payable (or prepayable) under any provision of this Agreement. 
  
 (iv) For purposes of the foregoing, “paid in full”
means payment of all amounts owing under the Loan Documents according to the terms thereof, including loan fees, service fees, professional fees, interest (and specifically including interest accrued after the commencement of any Insolvency
Proceeding), default interest, interest on interest, and expense reimbursements, whether or not the same would be or is allowed or disallowed in whole or in part in any Insolvency Proceeding. 
  
 (v) In the event of a direct conflict between the priority
provisions of this Section 2.4 and other provisions contained in any other Loan Document, it is the intention of the parties hereto that such priority provisions in such documents shall be read together and construed, to the fullest
extent possible, to be in concert with each other. In the event of any actual, irreconcilable conflict that cannot be resolved as aforesaid, the terms and provisions of this Section 2.4 shall control and govern. 
  

	 	2.5.	Overadvances. 

  
 If, at any time or for any reason, the amount of Obligations (other than Bank Product Obligations) owed by Borrowers to the Lender Group
pursuant to Sections 2.1 and 2.12 is greater than either the Dollar or percentage limitations set forth in Sections 2.1 or 2.12, (an “Overadvance”), Borrowers immediately shall pay to Agent, in cash, the
amount of such excess, which amount shall be used by Agent to reduce the Obligations in accordance with the priorities set forth in Section 2.4(b). In addition, Borrowers hereby promise to pay the Obligations (including principal,
interest, fees, costs, and expenses) in Dollars in full to the Lender Group as and when due and payable under the terms of this Agreement and the other Loan Documents. 
  

	 	2.6.	Interest Rates and Letter of Credit Fee: Rates, Payments, and Calculations. 

  
 (a) Interest Rates. Except as provided in clause (c) below, all Obligations (except for undrawn
Letters of Credit and except for Bank Product Obligations) that have been charged to the Loan Account pursuant to the terms hereof shall bear interest on the Daily Balance thereof as follows: (i) if the relevant Obligation is an Advance that is
a LIBOR Rate Loan, at a per annum rate equal to the LIBOR Rate plus the LIBOR Rate Margin, and (ii) otherwise, at a per annum rate equal to the Base Rate plus the Base Rate Margin. 
  

 -35- 

 The foregoing notwithstanding, at no time shall any portion of the Obligations (other
than Bank Product Obligations) bear interest on the Daily Balance thereof at a per annum rate less than 5.75%. To the extent that interest accrued hereunder at the rate set forth herein would be less than the foregoing minimum daily rate, the
interest rate chargeable hereunder for such day automatically shall be deemed increased to the minimum rate. 
  
 (b) Letter of Credit Fee. Borrowers shall pay Agent (for the ratable benefit of the Lenders with a Revolver Commitment, subject to
any letter agreement between Agent and individual Lenders), a Letter of Credit fee (in addition to the charges, commissions, fees, and costs set forth in Section 2.12(e)) which shall accrue at a rate equal to 2.25% per annum times
the Daily Balance of the undrawn amount of all outstanding Letters of Credit. 
  
 (c) Default Rate. Upon the occurrence and during the continuation of an Event of Default (and at the election of Agent or the Required Lenders), 
  
 (i) all Obligations (except for undrawn Letters of Credit and except for Bank Product Obligations) that have
been charged to the Loan Account pursuant to the terms hereof shall bear interest on the Daily Balance thereof at a per annum rate equal to 4 percentage points above the per annum rate otherwise applicable hereunder, and 
  
 (ii) the Letter of Credit fee provided for above shall be
increased to 4 percentage points above the per annum rate otherwise applicable hereunder. 
  
 (d) Payment. Interest, Letter of Credit fees, and all other fees payable hereunder shall be due and payable, in arrears, on the
first day of each month at any time that Obligations or Commitments are outstanding. Borrowers hereby authorize Agent, from time to time, without prior notice to Borrowers, to charge such interest and fees, all Lender Group Expenses (as and when
incurred), the charges, commissions, fees, and costs provided for in Section 2.12(e) (as and when accrued or incurred), the fees and costs provided for in Section 2.11 (as and when accrued or incurred), and all other payments
as and when due and payable under any Loan Document (including any amounts due and payable to Wells Fargo or its Affiliates in respect of Bank Products up to the amount of the then extant Bank Products Reserve) to Borrowers’ Loan Account, which
amounts thereafter shall constitute Advances hereunder and shall accrue interest at the rate then applicable to Advances hereunder. Any interest not paid when due shall be compounded by being charged to Borrowers’ Loan Account and shall
thereafter constitute Advances hereunder and shall accrue interest at the rate then applicable to Advances that are Base Rate Loans hereunder. 
  
 (e) Computation. All interest and fees chargeable under the Loan Documents shall be computed on the basis of a 360 day year for the
actual number of days elapsed. In the event the Base Rate is changed from time to time hereafter, the rates of

interest hereunder based upon the Base Rate automatically and immediately shall be increased or decreased by an amount equal to such change in the Base Rate.

  
 (f) Intent to Limit Charges to Maximum
Lawful Rate. In no event shall the interest rate or rates payable under this Agreement, plus any other amounts paid in connection herewith, exceed the highest rate permissible under any law that a court of competent jurisdiction shall, in a
final determination, deem applicable. Borrowers and the Lender Group, in executing and delivering this Agreement, intend legally to agree upon the rate or rates of interest and manner of payment stated within it; provided, however,
that, anything contained herein to the contrary notwithstanding, if said rate or rates of interest or manner of payment exceeds the maximum allowable under applicable law, then, ipso facto, as of the date of this Agreement, Borrowers are and
shall be liable only for the payment of such maximum as allowed by law, and payment received from Borrowers in excess of such legal maximum, whenever received, shall be applied to reduce the principal balance of the Obligations to the extent of such
excess. 
  

	 	2.7.	Cash Management. 

  
 (a) Companies shall (i) establish and maintain cash management services of a type and on terms satisfactory to Agent at one or more
of the banks set forth on Schedule 2.7(a) (each a “Cash Management Bank”), and shall request in writing and otherwise take such reasonable steps to ensure that all of its Account Debtors forward payment of the amounts owed by
them directly to such Cash Management Bank, and (ii) deposit or cause to be deposited promptly, and in any event no later than the first Business Day after the date of receipt thereof, all Collections (including those sent directly by Account
Debtors to a Cash Management Bank) into a bank account in Agent’s name (a “Cash Management Account”) at one of the Cash Management Banks. 
  

(b) Each Cash Management Bank shall establish and maintain Cash Management Agreements with Agent and Companies, in form and substance
acceptable to Agent. Each such Cash Management Agreement shall provide, among other things, that (i) all items of payment deposited in such Cash Management Account and proceeds thereof are held by such Cash Management Bank agent or
bailee-in-possession for Agent, (ii) the Cash Management Bank has no rights of setoff or recoupment or any other claim against the applicable Cash Management Account, other than for payment of its service fees and other charges directly related
to the administration of such Cash Management Account and for returned checks or other items of payment, and (iii) it immediately will forward by daily sweep all amounts in the applicable Cash Management Account to the Agent’s Account.

  
 (c) So long as no Default or Event of Default
has occurred and is continuing, Administrative Borrower may amend Schedule 2.7(a) or (b) to add or replace a Cash Management Account Bank or Cash Management Account; provided, however, that (i) such prospective
Cash Management Bank shall be satisfactory to Agent and Agent shall have consented in writing in advance to the opening of such Cash Management Account with the prospective Cash Management Bank, and (ii) prior to the time of the opening of such
Cash Management Account, Companies and such prospective Cash Management Bank shall 

  

 -37- 

 
have executed and delivered to Agent a Cash Management Agreement. Companies shall close any of their Cash Management Accounts (and establish replacement cash
management accounts in accordance with the foregoing sentence) promptly and in any event within 30 days of notice from Agent that the creditworthiness of any Cash Management Bank is no longer acceptable in Agent’s reasonable judgment, or as
promptly as practicable and in any event within 60 days of notice from Agent that the operating performance, funds transfer, or availability procedures or performance of the Cash Management Bank with respect to Cash Management Accounts or
Agent’s liability under any Cash Management Agreement with such Cash Management Bank is no longer acceptable in Agent’s reasonable judgment. 
  
 (d) The Cash Management Accounts shall be cash collateral accounts, with all cash, checks and similar items of payment in such accounts
securing payment of the Obligations, and in which Companies are hereby deemed to have granted a Lien to Agent. 
  
 (e) Within 90 days after the Closing Date, Companies shall replace Bank of America as the Cash Management Banks with banks acceptable to
Agent. 
  

	 	2.8.	Crediting Payments; Float Charge. 

  
 The receipt of any payment item by Agent (whether from transfers to Agent by the Cash Management Banks pursuant to the Cash Management
Agreements or otherwise) shall not be considered a payment on account unless such payment item is a wire transfer of immediately available federal funds made to the Agent’s Account or unless and until such payment item is honored when presented
for payment. Should any payment item not be honored when presented for payment, then Borrowers shall be deemed not to have made such payment and interest shall be calculated accordingly. Anything to the contrary contained herein notwithstanding, any
payment item shall be deemed received by Agent only if it is received into the Agent’s Account on a Business Day on or before 11:00 a.m. (California time). If any payment item is received into the Agent’s Account on a non-Business Day or
after 11:00 a.m. (California time) on a Business Day, it shall be deemed to have been received by Agent as of the opening of business on the immediately following Business Day. From and after the Closing Date, Agent shall be entitled to charge
Borrowers for 1 Business Day of ‘clearance’ or ‘float’ at the rate applicable to Base Rate Loans under Section 2.6 on all Collections that are received by Borrowers (regardless of whether forwarded by the Cash
Management Banks to Agent). This across-the-board 1 Business Day clearance or float charge on all Collections is acknowledged by the parties to constitute an integral aspect of the pricing of the financing of Borrowers and shall apply irrespective
of whether or not there are any outstanding monetary Obligations; the effect of such clearance or float charge being the equivalent of charging 1 Business Day of interest on such Collections. The parties acknowledge and agree that the economic
benefit of the foregoing provisions of this Section 2.8 shall be for the exclusive benefit of Agent. 
  

	 	2.9.	Designated Account. 

  
 Agent is authorized to make the Advances, and Issuing Lender is authorized to issue the Letters of Credit, under this Agreement based upon
telephonic or other instructions 

  

 -38- 

 
received from anyone purporting to be an Authorized Person, or without instructions if pursuant to Section 2.6(d). Administrative Borrower agrees
to establish and maintain the Designated Account with the Designated Account Bank for the purpose of receiving the proceeds of the Advances requested by Borrowers and made by Agent or the Lenders hereunder. Unless otherwise agreed by Agent and
Administrative Borrower, any Advance, Agent Advance, or Swing Loan requested by Borrowers and made by Agent or the Lenders hereunder shall be made to the Designated Account. 
  

	 	2.10.	Maintenance of Loan Account; Statements of Obligations. 

  
 Agent shall maintain an account on its books in the name of Borrowers (the “Loan Account”) on which Borrowers will be
charged with all Advances (including Agent Advances and Swing Loans) made by Agent, Swing Lender, or the Lenders to Borrowers or for Borrowers’ account, the Letters of Credit issued by Issuing Lender for Borrowers’ account, and with all
other payment Obligations hereunder or under the other Loan Documents (except for Bank Product Obligations), including, accrued interest, fees and expenses, and Lender Group Expenses. In accordance with Section 2.8, the Loan Account will
be credited with all payments received by Agent from Borrowers or for Borrowers’ account, including all amounts received in the Agent’s Account from any Cash Management Bank. Agent shall render statements regarding the Loan Account to
Administrative Borrower, including principal, interest, fees, and including an itemization of all charges and expenses constituting Lender Group Expenses owing, and such statements shall be conclusively presumed to be correct and accurate and
constitute an account stated between Borrowers and the Lender Group unless, within 30 days after receipt thereof by Administrative Borrower, Administrative Borrower shall deliver to Agent written objection thereto describing the error or errors
contained in any such statements. 
  

	 	2.11.	Fees. 

  
 Borrowers shall pay to Agent the following fees and charges, which fees and charges shall be non-refundable when paid (irrespective of
whether this Agreement is terminated thereafter) and shall be apportioned among the Lenders in accordance with the terms of letter agreements between Agent and individual Lenders: 
  
 (a) Unused Line Fee. On the first day of each month during the term of this Agreement, an unused line
fee in the amount equal to 0.5% per annum times the result of (a) the Maximum Revolver Amount, less (b) the sum of (i) the average Daily Balance of Advances that were outstanding during the immediately preceding month, plus (ii)
the average Daily Balance of the Letter of Credit Usage during the immediately preceding month, 
  
 (b) Fee Letter Fees. As and when due and payable under the terms of the Fee Letter, Borrowers shall pay to Agent the fees set forth
in the Fee Letter, and 
  
 (c) Audit,
Appraisal, and Valuation Charges. For the separate account of Agent, audit, appraisal, and valuation fees and charges as follows, (i) a fee of $850 per 

  

 -39- 

 
day, per auditor, plus out-of-pocket expenses for each financial audit of a Borrower performed by personnel employed by Agent, (ii) a one time charge of
$5,000 plus out-of-pocket expenses for the establishment of electronic collateral reporting systems, (iii) actual charges paid or incurred by Agent for each appraisal of the Collateral, and (iv) the actual charges paid or incurred by Agent
if it elects to employ the services of one or more third Persons to perform financial audits of Borrowers, to appraise the Collateral, or any portion thereof, or to assess a Borrower’s business valuation. 
  

	 	2.12.	Letters of Credit 

  
 (a) Subject to the terms and conditions of this Agreement, the Issuing Lender agrees to issue letters of credit for the account of
Borrowers (each, an “L/C”) or to purchase participations or execute indemnities or reimbursement obligations (each such undertaking, an “L/C Undertaking”‘) with respect to letters of credit issued by an
Underlying Issuer (as of the Closing Date, the prospective Underlying Issuer is to be Wells Fargo) for the account of Borrowers. To request the issuance of an L/C or an L/C Undertaking (or the amendment, renewal, or extension of an outstanding L/C
or L/C Undertaking), Administrative Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Lender) to the Issuing Lender and Agent (reasonably in advance of
the requested date of issuance, amendment, renewal, or extension) a notice requesting the issuance of an L/C or L/C Undertaking, or identifying the L/C or L/C Undertaking to be amended, renewed, or extended, the date of issuance, amendment, renewal,
or extension, the date on which such L/C or L/C Undertaking is to expire, the amount of such L/C or L/C Undertaking, the name and address of the beneficiary thereof (or of the Underlying Letter of Credit, as applicable), and such other information
as shall be necessary to prepare, amend, renew, or extend such L/C or L/C Undertaking. If requested by the Issuing Lender, Borrowers also shall be an applicant under the application with respect to any Underlying Letter of Credit that is to be the
subject of an L/C Undertaking. The Issuing Lender shall have no obligation to issue a Letter of Credit if any of the following would result after giving effect to the requested Letter of Credit: 
  
 (i) the Letter of Credit Usage would exceed the Borrowing
Base less the amount of outstanding Advances, or 
  
 (ii) the Letter of Credit Usage would exceed $5,000,000, or 
  
 (iii) the Letter of Credit Usage would exceed the Maximum Revolver Amount less the then extant amount of outstanding Advances.

  
 Borrowers and the Lender Group acknowledge
and agree that certain Underlying Letters of Credit may be issued to support letters of credit that already are outstanding as of the Closing Date. Each Letter of Credit (and corresponding Underlying Letter of Credit) shall be in form and substance
acceptable to the Issuing Lender (in the exercise of its Permitted Discretion), including the requirement that the amounts payable thereunder must be payable in Dollars. If Issuing Lender is obligated to advance funds under 

  

 -40- 

 
a Letter of Credit, Borrowers immediately shall reimburse such L/C Disbursement to Issuing Lender by paying to Agent an amount equal to such L/C Disbursement
not later than 11:00 a.m., California time, on the date that such L/C Disbursement is made, if Administrative Borrower shall have received written or telephonic notice of such L/C Disbursement prior to 10:00 a.m., California time, on such date, or,
if such notice has not been received by Administrative Borrower prior to such time on such date, then not later than 11:00 a.m., California time, on (i) the Business Day that Administrative Borrower receives such notice, if such notice is
received prior to 10:00 a.m., California time, on the date of receipt, and, in the absence of such reimbursement, the L/C Disbursement immediately and automatically shall be deemed to be an Advance hereunder and, thereafter, shall bear interest at
the rate then applicable to Advances that are Base Rate Loans under Section 2.6. To the extent an L/C Disbursement is deemed to be an Advance hereunder, Borrowers’ obligation to reimburse such L/C Disbursement shall be discharged
and replaced by the resulting Advance. Promptly following receipt by Agent of any payment from Borrowers pursuant to this paragraph, Agent shall distribute such payment to the Issuing Lender or, to the extent that Lenders have made payments pursuant
to Section 2.12(c) to reimburse the Issuing Lender, then to such Lenders and the Issuing Lender as their interest may appear. 
  
 (b) Promptly following receipt of a notice of L/C Disbursement pursuant to Section 2.12(a), each Lender with a Revolver
Commitment agrees to fund its Pro Rata Share of any Advance deemed made pursuant to the foregoing subsection on the same terms and conditions as if Borrowers had requested such Advance and Agent shall promptly pay to Issuing Lender the amounts so
received by it from the Lenders. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Lender or the Lenders with Revolver Commitment,
the Issuing Lender shall be deemed to have granted to each Lender with a Revolver Commitment, and each Lender with a Revolver Commitment shall be deemed to have purchased, a participation in each Letter of Credit, in an amount equal to its Pro Rata
Share of the Risk Participation Liability of such Letter of Credit, and each such Lender agrees to pay to Agent, for the account of the Issuing Lender, such Lender’s Pro Rata Share of any payments made by the Issuing Lender under such Letter of
Credit. In consideration and in furtherance of the foregoing, each Lender with a Revolver Commitment hereby absolutely and unconditionally agrees to pay to Agent, for the account of the Issuing Lender, such Lender’s Pro Rata Share of each L/C
Disbursement made by the Issuing Lender and not reimbursed by Borrowers on the date due as provided in clause (a) of this Section, or of any reimbursement payment required to be refunded to Borrowers for any reason. Each Lender with a Revolver
Commitment acknowledges and agrees that its obligation to deliver to Agent, for the account of the Issuing Lender, an amount equal to its respective Pro Rata Share pursuant to this Section 2.12(b) shall be absolute and unconditional and
such remittance shall be made notwithstanding the occurrence or continuation of an Event of Default or Default or the failure to satisfy any condition set forth in Section 3 hereof. If any such Lender fails to make available to Agent the
amount of such Lender’s Pro Rata Share of any payments made by the Issuing Lender in respect of such Letter of Credit as provided in this Section, Agent (for the account of the Issuing Lender) shall be entitled to recover such amount on demand
from such Lender together with interest thereon at the Defaulting Lender Rate until paid in full. 
  

 -41- 

 (c) Each Borrower hereby agrees to indemnify, save, defend, and hold the Lender Group
harmless from any loss, cost, expense, or liability, and reasonable attorneys fees incurred by the Lender Group arising out of or in connection with any Letter of Credit; provided, however, that no Borrower shall be obligated hereunder
to indemnify for any loss, cost, expense, or liability that is caused by the gross negligence or willful misconduct of the Issuing Lender or any other member of the Lender Group. Each Borrower agrees to be bound by the Underlying Issuer’s
regulations and interpretations of any Underlying Letter of Credit or by Issuing Lender’s interpretations of any L/C issued by Issuing Lender to or for such Borrower’s account, even though this interpretation may be different from such
Borrower’s own, and each Borrower understands and agrees that the Lender Group shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrowers’ instructions or those contained in the
Letter of Credit or any modifications, amendments, or supplements thereto, except for those errors, negligence or mistakes that constitute the gross negligence or willful misconduct of the Lender Group. Each Borrower understands that the L/C
Undertakings may require Issuing Lender to indemnify the Underlying Issuer for certain costs or liabilities arising out of claims by Borrowers against such Underlying Issuer. Each Borrower hereby agrees to indemnify, save, defend, and hold the
Lender Group harmless with respect to any loss, cost, expense (including reasonable attorneys fees), or liability incurred by the Lender Group under any L/C Undertaking as a result of the Lender Group’s indemnification of any Underlying Issuer;
provided, however, that no Borrower shall be obligated hereunder to indemnify for any loss, cost, expense, or liability that is caused by the gross negligence or willful misconduct of the Issuing Lender or any other member of the
Lender Group. Nothing herein shall constitute a waiver of any claim under applicable law that Borrowers, as account parties, may have against the Issuing Lender or the Underlying Issuer in connection with an L/C or an L/C Undertaking, including
without limitation a claim for wrongful payment. 
  
 (d) Each Borrower hereby authorizes and directs any Underlying Issuer to deliver to the Issuing Lender all instruments, documents, and other writings and property received by such Underlying Issuer pursuant to such Underlying Letter of
Credit and to accept and rely upon the Issuing Lender’s instructions with respect to all matters arising in connection with such Underlying Letter of Credit and the related application. 
  
 (e) Any and all charges, commissions, fees, and costs
incurred by the Issuing Lender relating to Underlying Letters of Credit shall be Lender Group Expenses for purposes of this Agreement and immediately shall be reimbursable by Borrowers to Agent for the account of the Issuing Lender; it being
acknowledged and agreed by each Borrower that, as of the Closing Date, the issuance charge imposed by the prospective Underlying Issuer is .825% per annum times the face amount of each Underlying Letter of Credit, that such issuance charge may
be changed from time to time, and that the Underlying Issuer also imposes a schedule of charges for amendments, extensions, drawings, and renewals. 
  

 -42- 

 (f) If by reason of (i) any change in any applicable law, treaty, rule, or
regulation or any change in the interpretation or application thereof by any Governmental Authority, or (ii) compliance by the Underlying Issuer or the Lender Group with any direction, request, or requirement (irrespective of whether having the
force of law) of any Governmental Authority or monetary authority including, Regulation D of the Federal Reserve Board as from time to time in effect (and any successor thereto): 
  
 (i) any reserve, deposit, or similar requirement is or shall be imposed or modified in respect of any Letter
of Credit issued hereunder, or 
  
 (ii) there
shall be imposed on the Underlying Issuer or the Lender Group any other condition regarding any Underlying Letter of Credit or any Letter of Credit issued pursuant hereto; 
  
 and the result of the foregoing is to increase, directly or indirectly, the cost to the Lender Group of issuing, making, guaranteeing, or
maintaining any Letter of Credit or to reduce the amount receivable in respect thereof by the Lender Group, then, and in any such case, Agent may, at any time within a reasonable period after the additional cost is incurred or the amount received is
reduced, notify Administrative Borrower, and Borrowers shall pay on demand such amounts as Agent may specify to be necessary to compensate the Lender Group for such additional cost or reduced receipt, together with interest on such amount from the
date of such demand until payment in full thereof at the rate then applicable to Base Rate Loans hereunder. The determination by Agent of any amount due pursuant to this Section, as set forth in a certificate setting forth the calculation thereof in
reasonable detail, shall, in the absence of manifest or demonstrable error, be final and conclusive and binding on all of the parties hereto. 
  

	 	2.13.	LIBOR Option. 

  
 (a) Interest and Interest Payment Dates. In lieu of having interest charged at the rate based upon the Base Rate, Borrowers shall
have the option (the “LIBOR Option”) to have interest on all or a portion of the Advances be charged at a rate of interest based upon the LIBOR Rate. Interest on LIBOR Rate Loans shall be payable on the earliest of (i) the last
day of the Interest Period applicable thereto, (ii) the occurrence of an Event of Default in consequence of which the Required Lenders or Agent on behalf thereof elect to accelerate the maturity of all or any portion of the Obligations, or
(iii) termination of this Agreement pursuant to the terms hereof. On the last day of each applicable Interest Period, unless Administrative Borrower properly has exercised the LIBOR Option with respect thereto, the interest rate applicable to
such LIBOR Rate Loan automatically shall convert to the rate of interest then applicable to Base Rate Loans of the same type hereunder. At any time that an Event of Default has occurred and is continuing, Borrowers no longer shall have the option to
request that Advances bear interest at the LIBOR Rate and Agent shall have the right to convert the interest rate on all outstanding LIBOR Rate Loans to the rate then applicable to Base Rate Loans hereunder. 
  

 -43- 

 (b) LIBOR Election. 
  
 (i) Administrative Borrower may, at any time and from time to time, so long as no Event of Default has
occurred and is continuing, elect to exercise the LIBOR Option by notifying Agent prior to 11:00 a.m. (California time) at least 3 Business Days prior to the commencement of the proposed Interest Period (the “LIBOR Deadline”).
Notice of Administrative Borrower’s election of the LIBOR Option for a permitted portion of the Advances and an Interest Period pursuant to this Section shall be made by delivery to Agent of a LIBOR Notice received by Agent before the LIBOR
Deadline, or by telephonic notice received by Agent before the LIBOR Deadline (to be confirmed by delivery to Agent of a LIBOR Notice received by Agent prior to 5:00 p.m. (California time) on the same day. Promptly upon its receipt of each such
LIBOR Notice, Agent shall provide a copy thereof to each of the Lenders having a Revolver Commitment. 
  
 (ii) Each LIBOR Notice shall be irrevocable and binding on Borrowers. In connection with each LIBOR Rate Loan, each Borrower shall
indemnify, defend, and hold Agent and the Lenders harmless against any loss, cost, or expense incurred by Agent or any Lender as a result of (a) the payment of any principal of any LIBOR Rate Loan other than on the last day of an Interest
Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any LIBOR Rate Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure to borrow, convert, continue or
prepay any LIBOR Rate Loan on the date specified in any LIBOR Notice delivered pursuant hereto (such losses, costs, and expenses, collectively, “Funding Losses”). Funding Losses shall, with respect to Agent or any Lender, be deemed
to equal the amount determined by Agent or such Lender to be the excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such LIBOR Rate Loan had such event not occurred, at the LIBOR Rate that would
have been applicable thereto, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest
Period therefor), minus (ii) the amount of interest that would accrue on such principal amount for such period at the interest rate which Agent or such Lender would be offered were it to be offered, at the commencement of such period,
Dollar deposits of a comparable amount and period in the London interbank market. A certificate of Agent or a Lender delivered to Administrative Borrower setting forth any amount or amounts that Agent or such Lender is entitled to receive pursuant
to this Section shall be conclusive absent manifest error. 
  
 (iii) Borrowers shall have not more than 5 LIBOR Rate Loans in effect at any given time. Borrowers only may exercise the LIBOR Option for LIBOR Rate Loans of at least $1,000,000 and integral multiples of $500,000 in
excess thereof. 
  
 (c) Prepayments.
Borrowers may prepay LIBOR Rate Loans at any time; provided, however, that in the event that LIBOR Rate Loans are prepaid on any date that is 

  

 -44- 

 
not the last day of the Interest Period applicable thereto, including as a result of any automatic prepayment through the required application by Agent of
proceeds of Collections in accordance with Section 2.4(b) or for any other reason, including early termination of the term of this Agreement or acceleration of all or any portion of the Obligations pursuant to the terms hereof, each
Borrower shall indemnify, defend, and hold Agent and the Lenders and their Participants harmless against any and all Funding Losses in accordance with clause (b) above. 
  
 (d) Special Provisions Applicable to LIBOR Rate. 
  
 (i) The LIBOR Rate may be adjusted by Agent with respect to
any Lender on a prospective basis to take into account any additional or increased costs to such Lender of maintaining or obtaining any eurodollar deposits or increased costs due to changes in applicable law occurring subsequent to the commencement
of the then applicable Interest Period, including changes in tax laws (except changes of general applicability in corporate income tax laws) and changes in the reserve requirements imposed by the Board of Governors of the Federal Reserve System (or
any successor), excluding the Reserve Percentage, which additional or increased costs would increase the cost of funding loans bearing interest at the LIBOR Rate. In any such event, the affected Lender shall give Administrative Borrower and Agent
notice of such a determination and adjustment and Agent promptly shall transmit the notice to each other Lender and, upon its receipt of the notice from the affected Lender, Administrative Borrower may, by notice to such affected Lender
(y) require such Lender to furnish to Administrative Borrower a statement setting forth the basis for adjusting such LIBOR Rate and the method for determining the amount of such adjustment, or (z) repay the LIBOR Rate Loans with respect to
which such adjustment is made (together with any amounts due under clause (b)(ii) above). 
  
 (ii) In the event that any change in market conditions or any law, regulation, treaty, or directive, or any change therein or in the
interpretation of application thereof, shall at any time after the date hereof, in the reasonable opinion of any Lender, make it unlawful or impractical for such Lender to fund or maintain LIBOR Advances or to continue such funding or maintaining,
or to determine or charge interest rates at the LIBOR Rate, such Lender shall give notice of such changed circumstances to Agent and Administrative Borrower and Agent promptly shall transmit the notice to each other Lender and (y) in the case
of any LIBOR Rate Loans of such Lender that are outstanding, the date specified in such Lender’s notice shall be deemed to be the last day of the Interest Period of such LIBOR Rate Loans, and interest upon the LIBOR Rate Loans of such Lender
thereafter shall accrue interest at the rate then applicable to Base Rate Loans, and (z) Borrowers shall not be entitled to elect the LIBOR Option until such Lender determines that it would no longer be unlawful or impractical to do so.

  
 (e) No Requirement of Matched Funding.
Anything to the contrary contained herein notwithstanding, neither Agent, nor any Lender, nor any of their Participants, is required actually to acquire eurodollar deposits to fund or otherwise match 

  

 -45- 

 
fund any Obligation as to which interest accrues at the LIBOR Rate. The provisions of this Section shall apply as if each Lender or its Participants had
match funded any Obligation as to which interest is accruing at the LIBOR Rate by acquiring eurodollar deposits for each Interest Period in the amount of the LIBOR Rate Loans. 
  

	 	2.14.	Capital Requirements. 

  
 If, after the date hereof, any Lender determines that (i) the adoption of or change in any law, rule, regulation or guideline
regarding capital requirements for banks or bank holding companies, or any change in the interpretation or application thereof by any Governmental Authority charged with the administration thereof, or (ii) compliance by such Lender or its
parent bank holding company with any guideline, request or directive of any such entity regarding capital adequacy (whether or not having the force of law), the effect of reducing the return on such Lender’s or such holding company’s
capital as a consequence of such Lender’s Commitments hereunder to a level below that which such Lender or such holding company could have achieved but for such adoption, change, or compliance (taking into consideration such Lender’s or
such holding company’s then existing policies with respect to capital adequacy and assuming the full utilization of such entity’s capital) by any amount deemed by such Lender to be material, then such Lender may notify Administrative
Borrower and Agent thereof. Following receipt of such notice, Borrowers agree to pay such Lender on demand the amount of such reduction of return of capital as and when such reduction is determined, payable within 90 days after presentation by such
Lender of a statement in the amount and setting forth in reasonable detail such Lender’s calculation thereof and the assumptions upon which such calculation was based (which statement shall be deemed true and correct absent manifest error). In
determining such amount, such Lender may use any reasonable averaging and attribution methods. 
  

	 	2.15.	Joint and Several Liability of Borrowers. 

  
 (a) Each of Borrowers is accepting joint and several liability hereunder and under the other Loan Documents in consideration of the
financial accommodations to be provided by the Agent and the Lenders under this Agreement, for the mutual benefit, directly and indirectly, of each of Borrowers and in consideration of the undertakings of the other Borrowers to accept joint and
several liability for the Obligations. 
  
 (b)
Each of Borrowers, jointly and severally, hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor, joint and several liability with the other Borrowers, with respect to the payment and performance of all of the
Obligations (including, without limitation, any Obligations arising under this Section 2.15), it being the intention of the parties hereto that all the Obligations shall be the joint and several obligations of each Person composing
Borrowers without preferences or distinction among them. 
  
 (c) If and to the extent that any of Borrowers shall fail to make any payment with respect to any of the Obligations as and when due or to perform any of the 

  

 -46- 

 
Obligations in accordance with the terms thereof, then in each such event the other Persons composing Borrowers will make such payment with respect to, or
perform, such Obligation. 
  
 (d) The Obligations
of each Person composing Borrowers under the provisions of this Section 2.15 constitute the absolute and unconditional, full recourse Obligations of each Person composing Borrowers enforceable against each such Borrower to the full
extent of its properties and assets, irrespective of the validity, regularity or enforceability of this Agreement or any other circumstances whatsoever. 
  
 (e) Except as otherwise expressly provided in this Agreement, each Person composing Borrowers hereby waives notice of acceptance of its
joint and several liability, notice of any Advances or Letters of Credit issued under or pursuant to this Agreement, notice of the occurrence of any Default, Event of Default, or of any demand for any payment under this Agreement, notice of any
action at any time taken or omitted by Agent or Lenders under or in respect of any of the Obligations, any requirement of diligence or to mitigate damages and, generally, to the extent permitted by applicable law, all demands, notices and other
formalities of every kind in connection with this Agreement (except as otherwise provided in this Agreement). Each Person composing Borrowers hereby assents to, and waives notice of, any extension or postponement of the time for the payment of any
of the Obligations, the acceptance of any payment of any of the Obligations, the acceptance of any partial payment thereon, any waiver, consent or other action or acquiescence by Agent or Lenders at any time or times in respect of any default by any
Person composing Borrowers in the performance or satisfaction of any term, covenant, condition or provision of this Agreement, any and all other indulgences whatsoever by Agent or Lenders in respect of any of the Obligations, and the taking,
addition, substitution or release, in whole or in part, at any time or times, of any security for any of the Obligations or the addition, substitution or release, in whole or in part, of any Person composing Borrowers. Without limiting the
generality of the foregoing, each of Borrowers assents to any other action or delay in acting or failure to act on the part of any Agent or Lender with respect to the failure by any Person composing Borrowers to comply with any of its respective
Obligations, including, without limitation, any failure strictly or diligently to assert any right or to pursue any remedy or to comply fully with applicable laws or regulations thereunder, which might, but for the provisions of this
Section 2.15 afford grounds for terminating, discharging or relieving any Person composing Borrowers, in whole or in part, from any of its Obligations under this Section 2.15, it being the intention of each Person composing
Borrowers that, so long as any of the Obligations hereunder remain unsatisfied, the Obligations of such Person composing Borrowers under this Section 2.15 shall not be discharged except by performance and then only to the extent of such
performance. The Obligations of each Person composing Borrowers under this Section 2.15 shall not be diminished or rendered unenforceable by any winding up, reorganization, arrangement, liquidation, reconstruction or similar proceeding
with respect to any Person composing Borrowers or any Agent or Lender. The joint and several liability of the Persons composing Borrowers hereunder shall continue in full force and effect notwithstanding any absorption, merger, amalgamation or any
other change whatsoever in the name, constitution or place of formation of any of the Persons composing Borrowers or any Agent or Lender. 
  

 -47- 

 (f) Each Person composing Borrowers represents and warrants to Agent and Lenders that
such Borrower is currently informed of the financial condition of Borrowers and of all other circumstances which a diligent inquiry would reveal and which bear upon the risk of nonpayment of the Obligations. Each Person composing Borrowers further
represents and warrants to Agent and Lenders that such Borrower has read and understands the terms and conditions of the Loan Documents. Each Person composing Borrowers hereby covenants that such Borrower will continue to keep informed of
Borrowers’ financial condition, the financial condition of other guarantors, if any, and of all other circumstances which bear upon the risk of nonpayment or nonperformance of the Obligations. 
  
 (g) The provisions of this Section 2.15 are made
for the benefit of the Agent, the Lenders and their respective successors and assigns, and may be enforced by it or them from time to time against any or all of the Persons composing Borrowers as often as occasion therefor may arise and without
requirement on the part of any such Agent, Lender, successor or assign first to marshal any of its or their claims or to exercise any of its or their rights against any of the other Persons composing Borrowers or to exhaust any remedies available to
it or them against any of the other Persons composing Borrowers or to resort to any other source or means of obtaining payment of any of the Obligations hereunder or to elect any other remedy. The provisions of this Section 2.15 shall
remain in effect until all of the Obligations shall have been paid in full or otherwise fully satisfied. If at any time, any payment, or any part thereof, made in respect of any of the Obligations, is rescinded or must otherwise be restored or
returned by any Agent or Lender upon the insolvency, bankruptcy or reorganization of any of the Persons composing Borrowers, or otherwise, the provisions of this Section 2.15 will forthwith be reinstated in effect, as though such payment
had not been made. 
  
 (h) Each of the Persons
composing Borrowers hereby agrees that it will not enforce any of its rights of contribution or subrogation against the other Persons composing Borrowers with respect to any liability incurred by it hereunder or under any of the other Loan
Documents, any payments made by it to the Agent or the Lenders with respect to any of the Obligations or any collateral security therefor until such time as all of the Obligations have been paid in full in cash. Any claim which any Borrower may have
against any other Borrower with respect to any payments to any Agent or Lender hereunder or under any other Loan Documents are hereby expressly made subordinate and junior in right of payment, without limitation as to any increases in the
Obligations arising hereunder or thereunder, to the prior payment in full in cash of the Obligations and, in the event of any insolvency, bankruptcy, receivership, liquidation, reorganization or other similar proceeding under the laws of any
jurisdiction relating to any Borrower, its debts or its assets, whether voluntary or involuntary, all such Obligations shall be paid in full in cash before any payment or distribution of any character, whether in cash, securities or other property,
shall be made to any other Borrower therefor. 
  
 (i) Each of the Persons composing Borrowers hereby agrees that, after the occurrence and during the continuance of any Default or Event of Default, the payment of any amounts due with respect to the indebtedness owing by any Borrower to any
other Borrower is hereby subordinated to the prior payment in full in cash of the Obligations. 

  

 -48- 

 
Each Borrower hereby agrees that after the occurrence and during the continuance of any Default or Event of Default, such Borrower will not demand, sue for
or otherwise attempt to collect any indebtedness of any other Borrower owing to such Borrower until the Obligations shall have been paid in full in cash. If, notwithstanding the foregoing sentence, such Borrower shall collect, enforce or receive any
amounts in respect of such indebtedness, such amounts shall be collected, enforced and received by such Borrower as trustee for the Agent, and the Agent shall deliver any such amounts to the Administrative Agent for application to the Obligations in
accordance with Section 2.4(b). 
  
 (j) Each of the Credit Parties has jointly and severally guaranteed the Obligations of Borrowers pursuant to the Joint and Several Guaranty.

 This Agreement shall become effective upon the execution and delivery hereof by Companies, Agent, and the Lenders and shall continue in

under this Agreement immediately and without notice upon the occurrence and during the continuation of an Event of Default. 
  

	 	3.5.	Effect of Termination. 

  
 On the date of termination of this Agreement, all Obligations (including contingent reimbursement obligations of Borrowers with respect to

those Lenders with a Revolver Commitment in an amount equal to 105% of the then extant Letter of Credit Usage, or (ii) causing the original Letters of Credit to be returned to the Issuing Lender, and (b) providing cash collateral to be

in recordable form) as are reasonably necessary to release, as of record, the Agent’s Liens and all notices of security interests and liens previously filed by Agent with respect to the Obligations. 
  

 -53- 

	 	3.6.	Early Termination by Borrowers. 

  
 Borrowers have the option, at any time upon 90 days prior written notice by Administrative Borrower to Agent, to terminate this Agreement
by paying to Agent, for the benefit of the Lender Group, in cash, the Obligations (including (a) either (i) providing cash collateral to be held by Agent for the benefit of those Lenders with a Revolver Commitment in an amount equal to
105% of the then extant Letter of Credit Usage, or (ii) causing the original Letters of Credit to be returned to the Issuing Lender, and (b) providing cash collateral to be held by Agent for the benefit of Wells Fargo or its Affiliates
with respect to the then extant Bank Products Obligations), in full, together with the Applicable Prepayment Premium (to be allocated based upon letter agreements between Agent and individual Lenders). If Administrative Borrower has sent a notice of
termination pursuant to the provisions of this Section, then the Commitments shall terminate and Borrowers shall be obligated to repay the Obligations (including (a) either (i) providing cash collateral to be held by Agent for the benefit
of those Lenders with a Revolver Commitment in an amount equal to 105% of the then extant Letter of Credit Usage, or (ii) causing the original Letters of Credit to be returned to the Issuing Lender, and (b) providing cash collateral to be
held by Agent for the benefit of Wells Fargo or its Affiliates with respect to the then extant Bank Products Obligations), in full, together with the Applicable Prepayment Premium, on the date set forth as the date of termination of this Agreement
in such notice; provided, that Borrowers shall not be obligated to pay the Applicable Prepayment Premium if the Obligations are repaid in full with proceeds of a financing provided by Wells Fargo. In the event of the termination of this Agreement
and repayment of the Obligations at any time prior to the Maturity Date, for any other reason, including (a) termination upon the election of the Required Lenders to terminate after the occurrence of an Event of Default, (b) foreclosure
and sale of Collateral, (c) sale of the Collateral in any Insolvency Proceeding, or (iv) restructure, reorganization or compromise of the Obligations by the confirmation of a plan of reorganization, or any other plan of compromise,
restructure, or arrangement in any Insolvency Proceeding, then, in view of the impracticability and extreme difficulty of ascertaining the actual amount of damages to the Lender Group or profits lost by the Lender Group as a result of such early
termination, and by mutual agreement of the parties as to a reasonable estimation and calculation of the lost profits or damages of the Lender Group, Borrowers shall pay the Applicable Prepayment Premium to Agent (to be allocated based upon letter
agreements between Agent and individual Lenders), measured as of the date of such termination.

interest in all currently existing and hereafter acquired or arising Collateral in order to secure prompt repayment of any and all of the Obligations in accordance with the terms and conditions of the Loan Documents and in order to secure prompt
performance by Companies of each of their covenants and duties under the Loan Documents. The Agent’s Liens in and to the Collateral shall attach to all 

  

 -54- 

 
Collateral without further act on the part of Agent or Companies. Anything contained in this Agreement or any other Loan Document to the contrary

	 	4.3.	Collection of Accounts, General Intangibles, and Negotiable Collateral. 

  
 At any time after the occurrence and during the continuation of an Event of Default, Agent or Agent’s
designee may (a) notify Account Debtors of Companies that the Accounts, chattel paper, or General Intangibles have been assigned to Agent or that Agent has a security interest therein, or (b) collect the Accounts, chattel paper, or General
Intangibles directly and charge the collection costs and expenses to the Loan Account. Each Company agrees that it will hold in trust for the Lender Group, as the Lender Group’s trustee, any Collections that it receives and immediately will
deliver said Collections to Agent or a Cash Management Bank in their original form as received by the applicable Company. 
  

	 	4.4.	Delivery of Additional Documentation Required. 

  
 At any time upon the request of Agent, Companies shall execute and deliver to Agent, any and all financing statements, original financing
statements in lieu of continuation statements, fixture filings, security agreements, pledges, assignments, endorsements of certificates of title, and all other documents (the “Additional Documents”) that Agent may request in its
Permitted Discretion, in form and substance satisfactory to Agent, to perfect and continue perfected or better perfect the Agent’s Liens in the Collateral (whether now owned or hereafter arising or acquired), to create and perfect Liens in
favor of Agent in any Real Property acquired after the Closing Date, and in order to fully consummate all of the transactions contemplated hereby and under the other Loan Documents. To the maximum extent permitted by applicable law, each Company
authorizes Agent to execute any such Additional Documents in the applicable Company’s name and authorize Agent to file such executed Additional Documents in any appropriate filing office. In addition, on a quarterly basis (or more frequent
periodic basis as Agent shall require), Companies shall (a) provide Agent with a report of all new patentable, copyrightable, or trademarkable materials acquired or generated by Companies during the prior period, (b) cause all patents,
copyrights, and trademarks acquired or generated by Companies that are not already the subject of a registration with the appropriate filing office (or an application therefor diligently prosecuted) to be registered with such appropriate filing
office in a manner sufficient to impart constructive notice of Companies’ ownership thereof, and (c) cause to be prepared, executed, and delivered to Agent supplemental schedules to the applicable Loan Documents to identify such patents,
copyrights, and trademarks as being subject to the security interests created thereunder. 
  

 -55- 

	 	4.5.	Power of Attorney. 

  
 Each Company hereby irrevocably makes, constitutes, and appoints Agent (and any of Agent’s officers, employees, or agents designated
by Agent) as such Company’s true and lawful attorney, with power to (a) if such Company refuses to, or fails timely to execute and deliver any of the documents described in Section 4.4, sign the name of such Company on any of
the documents described in Section 4.4, (b) at any time that an Event of Default has occurred and is continuing, sign such Company’s name on any invoice or bill of lading relating to the Collateral, drafts against Account
Debtors, or notices to Account Debtors, (c) send requests for verification of Accounts, (d) endorse such Company’s name on any Collection item that may come into the Lender Group’s possession, (e) at any time that an Event
of Default has occurred and is continuing, make, settle, and adjust all claims under such Company’s policies of insurance and make all determinations and decisions with respect to such policies of insurance, and (f) at any time that an
Event of Default has occurred and is continuing, settle and adjust disputes and claims respecting the Accounts, chattel paper, or General Intangibles directly with Account Debtors, for amounts and upon terms that Agent determines to be reasonable,
and Agent may cause to be executed and delivered any documents and releases that Agent determines to be necessary. The appointment of Agent as each Company’s attorney, and each and every one of its rights and powers, being coupled with an
interest, is irrevocable until all of the Obligations have been fully and finally repaid and performed and the Lender Group’s obligations to extend credit hereunder are terminated. 
  

	 	4.6.	Right to Inspect. 

  
 Agent and each Lender (through any of their respective officers, employees, or agents) shall have the right, from time to time hereafter
to inspect the Books and to check, test, and appraise the Collateral in order to verify Companies’ financial condition or the amount, quality, value, condition of, or any other matter relating to, the Collateral. 
  

	 	4.7.	Control Agreements. 

  
 Each Company agrees that it will not transfer assets out of any Securities Accounts other than as permitted under Section 7.19

any Securities Accounts or other Investment Property shall be modified by Companies without the prior written consent of Agent. Upon the occurrence and during the continuance of a Default or Event of Default, Agent may notify any securities
intermediary to liquidate the applicable Securities Account or any related Investment Property maintained or held thereby and remit the proceeds thereof to the Agent’s Account.

	9.	THE LENDER GROUP’S RIGHTS AND REMEDIES. 

  

	 	9.1.	Rights and Remedies. 

  
 Upon the occurrence, and during the continuation, of an Event of Default, the Required Lenders (at their election but without notice of
their election and without demand) may authorize and instruct Agent to do any one or more of the following on behalf of the Lender Group (and Agent, acting upon the instructions of the Required Lenders, shall do the same on behalf of the Lender
Group), all of which are authorized by Companies: 
  
 (a) Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and payable; 
  
 (b) Cease advancing money or extending credit to or for the benefit of Borrowers under this Agreement, under any of the Loan Documents, or
under any other agreement between Borrowers and the Lender Group; 
  
 (c) Terminate this Agreement and any of the other Loan Documents as to any future liability or obligation of the Lender Group, but without affecting any of the Agent’s Liens in the Collateral and without
affecting the Obligations; 
  
 (d) Settle or
adjust disputes and claims directly with Account Debtors for amounts and upon terms which Agent considers advisable, and in such cases, Agent will credit the Loan Account with only the net amounts received by Agent in payment of such disputed
Accounts after deducting all Lender Group Expenses incurred or expended in connection therewith; 
  
 (e) Cause Companies to hold all returned Inventory in trust for the Lender Group, segregate all returned Inventory from all other assets
of Companies or in Companies’ possession and conspicuously label said returned Inventory as the property of the Lender Group; 
  
 (f) Without notice to or demand upon any Company, make such payments and do such acts as Agent considers necessary or reasonable to
protect its security interests in the Collateral. Each Company agrees to assemble the Collateral if Agent so requires, and to 

  

 -78- 

 
make the Collateral available to Agent at a place that Agent may designate which is reasonably convenient to both parties. Each Company authorizes Agent to
enter the premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any Lien that in Agent’s determination appears to conflict with the
Agent’s Liens and to pay all expenses incurred in connection therewith and to charge Borrowers’ Loan Account therefor. With respect to any of Companies’ owned or leased premises, each Company hereby grants Agent a license to enter
into possession of such premises and to occupy the same, without charge, in order to exercise any of the Lender Group’s rights or remedies provided herein, at law, in equity, or otherwise; 
  
 (g) Without notice to any Company (such notice being
expressly waived), and without constituting a retention of any collateral in satisfaction of an obligation (within the meaning of the Code), set off and apply to the Obligations any and all (i) balances and deposits of any Company held by the
Lender Group (including any amounts received in the Cash Management Accounts), or (ii) Indebtedness at any time owing to or for the credit or the account of any Company held by the Lender Group; 
  
 (h) Hold, as cash collateral, any and all balances and
deposits of any Company held by the Lender Group, and any amounts received in the Cash Management Accounts, to secure the full and final repayment of all of the Obligations; 
  
 (i) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell
(in the manner provided for herein) the Collateral. Each Company hereby grants to Agent a license or other right to use, without charge, such Company’s labels, patents, copyrights, trade secrets, trade names, trademarks, service marks, and
advertising matter, or any property of a similar nature, as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and such Company’s rights under all licenses and all franchise agreements
shall inure to the Lender Group’s benefit; 
  
 (j) Sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Companies’ premises) as Agent determines is
commercially reasonable. It is not necessary that the Collateral be present at any such sale; 
  
 (k) Agent shall give notice of the disposition of the Collateral as follows: 
  
 (i) Agent shall give Administrative Borrower (for the
benefit of the applicable Company) a notice in writing of the time and place of public sale, or, if the sale is a private sale or some other disposition other than a public sale is to be made of the Collateral, the time on or after which the private
sale or other disposition is to be made; and 
  
 (ii) The notice shall be personally delivered or mailed, postage prepaid, to Administrative Borrower as provided in Section 12, at least 10 days before the earliest time of disposition set forth in the notice; no notice needs to
be given prior 

  

 -79- 

 
to the disposition of any portion of the Collateral that is perishable or threatens to decline speedily in value or that is of a type customarily sold on a
recognized market; 
  
 (l) Agent, on behalf of
the Lender Group may credit bid and purchase at any public sale; 
  
 (m) Agent may seek the appointment of a receiver or keeper to take possession of all or any portion of the Collateral or to operate same and, to the maximum extent permitted by law, may seek the appointment of such a
receiver without the requirement of prior notice or a hearing; 
  
 (n) The Lender Group shall have all other rights and remedies available to it at law or in equity pursuant to any other Loan Documents; and 
  
 (o) Any deficiency that exists after disposition of the Collateral as provided above will be paid
immediately by Companies. Any excess will be returned, without interest and subject to the rights of third Persons, by Agent to Administrative Borrower (for the benefit of the applicable Company). 
  

	 	9.2.	Remedies Cumulative. 

  
 The rights and remedies of the Lender Group under this Agreement, the other Loan Documents, and all other agreements shall be cumulative.
The Lender Group shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by the Lender Group of one right or remedy shall be deemed an election, and no waiver by the Lender
Group of any Event of Default shall be deemed a continuing waiver. No delay by the Lender Group shall constitute a waiver, election, or acquiescence by it. 
  

	10.	TAXES AND EXPENSES. 

  
 If any Company fails to pay any monies (whether taxes, assessments, insurance premiums, or, in the case of leased properties or assets,
rents or other amounts payable under such leases) due to third Persons, or fails to make any deposits or furnish any required proof of payment or deposit, all as required under the terms of this Agreement, then, Agent, in its sole discretion and
without prior notice to any Company, may do any or all of the following: (a) make payment of the same or any part thereof, (b) set up such reserves in Borrowers’ Loan Account as Agent deems necessary to protect the Lender Group from
the exposure created by such failure, or (c) in the case of the failure to comply with Section 6.8 hereof, obtain and maintain insurance policies of the type described in Section 6.8 and take any action with respect to
such policies as Agent deems prudent. Any such amounts paid by Agent shall constitute Lender Group Expenses and any such payments shall not constitute an agreement by the Lender Group to make similar payments in the future or a waiver by the Lender
Group of any Event of Default under this Agreement. Agent need not inquire as to, or contest the validity of, any such expense, tax, or Lien and the receipt of the usual official notice for the payment thereof shall be conclusive evidence that the
same was validly due and owing. 
  

 -80- 

	11.	WAIVERS; INDEMNIFICATION. 

  

	 	11.1.	 Demand; Protest; etc. 

  
 Each Company waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, nonpayment at
maturity, release, compromise, settlement, extension, or renewal of documents, instruments, chattel paper, and guarantees at any time held by the Lender Group on which any such Company may in any way be liable. 
  

	 	11.2.	 The Lender Group’s Liability for Collateral. 

  
 Each Company hereby agrees that: (a) so long as the Lender Group complies with its obligations, if any, under the Code, Agent shall
not in any way or manner be liable or responsible for: (i) the safekeeping of the Collateral, (ii) any loss or damage thereto occurring or arising in any manner or fashion from any cause, (iii) any diminution in the value thereof, or
(iv) any act or default of any carrier, warehouseman, bailee, forwarding agency, or other Person, and (b) all risk of loss, damage, or destruction of the Collateral shall be borne by Companies. 
  

	 	11.3.	 Indemnification. 

  
 Each Company shall pay, indemnify, defend, and hold the Agent-Related Persons, the Lender-Related Persons with respect to each Lender,
each Participant, and each of their respective officers, directors, employees, agents, and attorneys-in-fact (each, an “Indemnified Person”) harmless (to the fullest extent permitted by law) from and against any and all claims,
demands, suits, actions, investigations, proceedings, and damages, and all reasonable attorneys fees and disbursements and other costs and expenses actually incurred in connection therewith (as and when they are incurred and irrespective of whether
suit is brought), at any time asserted against, imposed upon, or incurred by any of them (a) in connection with or as a result of or related to the execution, delivery, enforcement, performance, or administration of this Agreement, any of the
other Loan Documents, or the transactions contemplated hereby or thereby, and (b) with respect to any investigation, litigation, or proceeding related to this Agreement, any other Loan Document, or the use of the proceeds of the credit provided
hereunder (irrespective of whether any Indemnified Person is a party thereto), or any act, omission, event, or circumstance in any manner related thereto (all the foregoing, collectively, the “Indemnified Liabilities”). The
foregoing to the contrary notwithstanding, Companies shall have no obligation to any Indemnified Person under this Section 11.3 with respect to any Indemnified Liability that a court of competent jurisdiction finally determines to have
resulted from the gross negligence or willful misconduct of such Indemnified Person. This provision shall survive the termination of this Agreement and the repayment of the Obligations. If any Indemnified Person makes any payment to any other
Indemnified Person with respect to an Indemnified Liability as to which Companies were required to indemnify the Indemnified Person receiving such 

  

 -81- 

 
payment, the Indemnified Person making such payment is entitled to be indemnified and reimbursed by Companies with respect thereto. WITHOUT LIMITATION, THE
FOREGOING INDEMNITY SHALL APPLY TO EACH INDEMNIFIED PERSON WITH RESPECT TO INDEMNIFIED LIABILITIES WHICH IN WHOLE OR IN PART CAUSED BY OR ARISE OUT OF ANY NEGLIGENT ACT OR OMISSION OF SUCH INDEMNIFIED PERSON OR OF ANY OTHER PERSON. 
  

	12.	NOTICES.

other Loan Document shall be in writing and (except for financial statements and other informational documents which may be sent by first-class mail, postage prepaid) shall be personally delivered or sent by registered or certified mail (postage

	14.	ASSIGNMENTS AND PARTICIPATIONS; SUCCESSORS. 

  

	 	14.1.	Assignments and Participations. 

  
 (a) Any Lender may, with the written consent of Agent (provided that no written consent of Agent shall be required in connection with any
assignment and delegation by a Lender to an Eligible Transferee), assign and delegate to one or more assignees (each an “Assignee”) all, or any ratable part of all, of the Obligations, the Commitments and the other rights and
obligations of such Lender hereunder and under the other Loan Documents, in a minimum amount of $5,000,000 (provided, that so long as no Event of Default exists and the Maximum Revolving Amount does not exceed $22,500,000, there shall be no more
than four Lenders holding commitments at any time and Bank of America National Association shall not be one of the Lenders); provided, however, that Companies and Agent may continue to deal solely and directly with such Lender in

and Agent by such Lender and the Assignee, (ii) such Lender and its Assignee have delivered to Administrative Borrower and Agent an Assignment and Acceptance in form and substance satisfactory to Agent, and (iii) the assignor Lender or
Assignee has paid to Agent for Agent’s separate account a processing fee in the amount of $5,000. Anything contained herein to the contrary notwithstanding, the consent of Agent shall not be required (and payment of any fees shall not be
required) if such assignment is in connection with any merger, consolidation, sale, transfer, or other disposition of all or any substantial portion of the business or loan portfolio of such Lender. 
  
 (b) From and after the date that Agent notifies the assignor
Lender (with a copy to Administrative Borrower) that it has received an executed Assignment and Acceptance and payment of the above-referenced processing fee, (i) the Assignee thereunder shall be a party hereto and, to the extent that rights
and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, shall have the rights and obligations of a Lender under the Loan Documents, and (ii) the assignor Lender shall, to the extent that rights and
obligations hereunder and under the other Loan Documents have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (except with respect to Section 11.3 hereof) and be released from its obligations under
this Agreement (and in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement and the other Loan Documents, such Lender shall cease to be a party
hereto and thereto), and such assignment shall affect a novation between Borrowers and the Assignee. 
  
 (c) By executing and delivering an Assignment and Acceptance, the assigning Lender thereunder and the Assignee thereunder confirm to and
agree with each

 (d) Immediately upon each Assignee’s making its processing fee payment under the Assignment and Acceptance and receipt and
acknowledgment by Agent of such fully executed Assignment and Acceptance, this Agreement shall be deemed to be amended to the extent, but only to the extent, necessary to reflect the addition of the Assignee and the resulting adjustment of the
Commitments arising therefrom. The Commitment allocated to each Assignee shall reduce such Commitments of the assigning Lender pro tanto. 
  
 (e) Any Lender may at any time, with the written consent of Agent, sell to one or more commercial banks, financial institutions, or other
Persons not Affiliates of such Lender (a “Participant”) participating interests in its Obligations, the Commitment, and the other rights and interests of that Lender (the “Originating Lender”) hereunder and under
the other Loan Documents (provided that no written consent of Agent shall be required in connection with any sale of any such participating interests by a Lender to an Eligible Transferee); provided, however, that (i) the
Originating Lender shall remain a “Lender” for all purposes of this Agreement and the other Loan Documents and the Participant receiving the participating interest in the Obligations, the Commitments, and the other rights and interests of

consent or waiver with respect to this Agreement or of any other Loan Document would (A) extend the final maturity date of the Obligations hereunder in
which such Participant is participating, (B) reduce the interest rate applicable to the Obligations hereunder in which such Participant is participating, (C) release all or a material portion of the Collateral or guaranties (except to the
extent expressly provided herein or in any of the Loan Documents) supporting the Obligations hereunder in which such Participant is participating, (D) postpone the payment of, or reduce the amount of, the interest or fees payable to such
Participant through such Lender, or (E) change the amount or due dates of scheduled principal repayments or prepayments or premiums; and (v) all amounts payable by Companies hereunder shall be determined as if such Lender had not sold such
participation; except that, if amounts outstanding under this Agreement are due and unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the
right of set-off in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement. The rights of any
Participant only shall be derivative through the Originating Lender with whom such Participant participates and no Participant shall have any rights under this Agreement or the other Loan Documents or any direct rights as to the other Lenders,

interest in, or pledge, all or any portion of its rights under and interest in this Agreement in favor of any Federal Reserve Bank in accordance with Regulation A of the Federal Reserve Bank or U.S. Treasury Regulation 31 CFR § 203.14, and such
Federal Reserve Bank may enforce such pledge or security interest in any manner permitted under applicable law. 
  

	 	14.2.	 Successors. 

  
 This Agreement shall bind and inure to the benefit of the respective successors and assigns of each of the parties; provided,
however, that Companies may not assign this Agreement or any rights or duties hereunder without the Lenders’ prior written consent and any prohibited assignment shall be absolutely void ab initio. No consent to assignment by the
Lenders shall release any Company from its Obligations. A Lender may assign this Agreement and the other Loan Documents and its rights and duties hereunder and thereunder pursuant to Section 14.1 hereof and, except as expressly required
pursuant to Section 14.1 hereof, no consent or approval by any Company is required in connection with any such assignment.

	15.	AMENDMENTS; WAIVERS. 

  

	 	15.1.	Amendments and Waivers. 

  
 No amendment or waiver of any provision of this Agreement or any other Loan Document, and no consent with respect to any departure by
Companies therefrom, shall be effective unless the same shall be in writing and signed by the Required Lenders (or by Agent at the written request of the Required Lenders) and Administrative Borrower (on behalf of all Companies) and then any such
waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no such waiver, amendment, or consent shall, unless in writing and signed by all of the Lenders
affected thereby and Administrative Borrower (on behalf of all Companies) and acknowledged by Agent, do any of the following: 
  
 (a) increase or extend any Commitment of any Lender, 
  
 (b) postpone or delay any date fixed by this Agreement or any other Loan Document for any payment of
principal, interest, fees, or other amounts due hereunder or under any other Loan Document,

 (j) change the definition of Borrowing Base or the definitions of Eligible Accounts, Maximum Revolver Amount, or change Section 2.
1 (b); or 
  
 (k) amend any of the provisions
of Section 16. 
  
 and, provided further,
however, that no amendment, waiver or consent shall, unless in writing and signed by Agent, Issuing Lender, or Swing Lender, affect the rights or duties of Agent, Issuing Lender, or Swing Lender, as applicable, under this Agreement or any
other Loan Document. The foregoing notwithstanding, any amendment, modification, waiver, 

  

 -87- 

 
consent, termination, or release of, or with respect to, any provision of this Agreement or any other Loan Document that relates only to the relationship of
the Lender Group among themselves, and that does not affect the rights or obligations of Companies, shall not require consent by or the agreement of Companies. 
  

	 	15.2.	Replacement of Holdout Lender. 

  
 If any action to be taken by the Lender Group or Agent hereunder requires the unanimous consent, authorization, or agreement of all
Lenders, and a Lender (“Holdout Lender”) fails to give its consent, authorization, or agreement, then Agent, upon at least 5 Business Days prior irrevocable notice to the Holdout Lender, may permanently replace the Holdout Lender
with one or more substitute Lenders (each, a “Replacement Lender”), and the Holdout Lender shall have not right to refuse to be replaced hereunder. Such notice to replace the Holdout Lender shall specify an effective date for such
replacement, which date shall not be later than 15 Business Days after the date such notice is given. 
  
 Prior to the effective date of such replacement, the Holdout Lender and each Replacement Lender shall execute and deliver an Assignment
and Acceptance Agreement, subject only to the Holdout Lender being repaid its share of the outstanding Obligations (including an assumption of its Pro Rata Share of the Risk Participation Liability) without any premium or penalty of any kind
whatsoever. If the Holdout Lender shall refuse or fail to execute and deliver any such Assignment and Acceptance Agreement prior to the effective date of such replacement, the Holdout Lender shall be deemed to have executed and delivered such
Assignment and Acceptance Agreement. The replacement of any Holdout Lender shall be made in accordance with the terms of Section 14.1. Until such time as the Replacement Lenders shall have acquired all of the Obligations, the
Commitments, and the other rights and obligations of the Holdout Lender hereunder and under the other Loan Documents, the Holdout Lender shall remain obligated to make the Holdout Lender’s Pro Rata Share of Advances and to purchase a
participation in each Letter of Credit, in an amount equal to its Pro Rata Share of the Risk Participation Liability of such Letter of Credit. 
  

	 	15.3.	No Waivers; Cumulative Remedies. 

  
 No failure by Agent or any Lender to exercise any right, remedy, or option under this Agreement or, any other Loan Document, or delay by
Agent or any Lender in exercising the same, will operate as a waiver thereof. No waiver by Agent or any Lender will be effective unless it is in writing, and then only to the extent specifically stated. No waiver by Agent or any Lender on any
occasion shall affect or diminish Agent’s and each Lender’s rights thereafter to require strict performance by Companies of any provision of this Agreement. Agent’s and each Lender’s rights under this Agreement and the other Loan
Documents will be cumulative and not exclusive of any other right or remedy that Agent or any Lender may have. 
  

 -88- 

	16.	AGENT; THE LENDER GROUP. 

  

	 	16.1.	Appointment and Authorization of Agent. 

  
 Each Lender hereby designates and appoints Foothill as its representative under this Agreement and the other Loan Documents and each
Lender hereby irrevocably authorizes Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to Agent by the terms of
this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto. Agent agrees to act as such on the express conditions contained in this Section 16. The provisions of this Section 16
are solely for the benefit of Agent, and the Lenders, and Companies shall have no rights as a third party beneficiary of any of the provisions contained herein. Any provision to the contrary contained elsewhere in this Agreement or in any other Loan
Document notwithstanding, Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall Agent have or be deemed to have any fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against Agent; it being expressly understood and agreed that the use of the word “Agent” is for
convenience only, that Foothill is merely the representative of the Lenders, and only has the contractual duties set forth herein. Except as expressly otherwise provided in this Agreement, Agent shall have and may use its sole discretion with
respect to exercising or refraining from exercising any discretionary rights or taking or refraining from taking any actions that Agent expressly is entitled to take or assert under or pursuant to this Agreement and the other Loan Documents. Without
limiting the generality of the foregoing, or of any other provision of the Loan Documents that provides rights or powers to Agent, Lenders agree that Agent shall have the right to exercise the following powers as long as this Agreement remains in
effect: (a) maintain, in accordance with its customary business practices, ledgers and records reflecting the status of the Obligations, the Collateral, the Collections, and related matters, (b) execute or file any and all financing or
similar statements or notices, amendments, renewals, supplements, documents, instruments, proofs of claim, notices and other written agreements with respect to the Loan Documents, (c) make Advances, for itself or on behalf of Lenders as
provided in the Loan Documents, (d) exclusively receive, apply, and distribute the Collections as provided in the Loan Documents, (e) open and maintain such bank accounts and cash management accounts as Agent deems necessary and
appropriate in accordance with the Loan Documents for the foregoing purposes with respect to the Collateral and the Collections, (f) perform, exercise, and enforce any and all other rights and remedies of the Lender Group with respect to
Companies, the Obligations, the Collateral, the Collections, or otherwise related to any of same as provided in the Loan Documents, and (g) incur and pay such Lender Group Expenses as Agent may deem necessary or appropriate for the performance
and fulfillment of its functions and powers pursuant to the Loan Documents. 
  

 -89- 

	 	16.2.	Delegation of Duties. 

  
 Agent may execute any of its duties under this Agreement or any other Loan Document by or through agents, employees or attorneys-in-fact
and shall be entitled to advice of counsel concerning all matters pertaining to such duties. Agent shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects as long as such selection was made without
gross negligence or willful misconduct. 
  

	 	16.3.	Liability of Agent. 

  
 None of the Agent-Related Persons shall (i) be liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct), or (ii) be responsible in any manner to any of the Lenders for any recital,
statement, representation or warranty made by any Company or any Subsidiary or Affiliate of any Company, or any officer or director thereof, contained in this Agreement or in any other Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of any Company or any other party to any Loan Document to perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the Books or properties of Companies or the books or records or properties of any of Companies’
Subsidiaries or Affiliates. 
  

	 	16.4.	Reliance by Agent. 

  
 Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate,
affidavit, letter, telegram, facsimile, telex or telephone message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent, or made by the proper Person or Persons, and upon advice and
statements of legal counsel (including counsel to Companies or counsel to any Lender), independent accountants and other experts selected by Agent. Agent shall be fully justified in failing or refusing to take any action under this Agreement or any
other Loan Document unless Agent shall first receive such advice or concurrence of the Lenders as it deems appropriate and until such instructions are received, Agent shall act, or refrain from acting, as it deems advisable. If Agent so requests, it
shall first be indemnified to its reasonable satisfaction by Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Lenders and such request and any action taken or failure to act pursuant thereto shall be binding upon all of the
Lenders. 
  

 -90- 

	 	16.5.	Notice of Default or Event of Default. 

  
 Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, except with respect to
defaults in the payment of principal, interest, fees, and expenses required to be paid to Agent for the account of the Lenders, except with respect to Events of Default of which Agent has actual knowledge, unless Agent shall have received written
notice from a Lender or Administrative Borrower referring to this Agreement, describing such Default or Event of Default, and stating that such notice is a “notice of default.” Agent promptly will notify the Lenders of its receipt of any
such notice or of any Event of Default of which Agent has actual knowledge. If any Lender obtains actual knowledge of any Event of Default, such Lender promptly shall notify the other Lenders and Agent of such Event of Default. Each Lender shall be
solely responsible for giving any notices to its Participants, if any. Subject to Section 16.4, Agent shall take such action with respect to such Default or Event of Default as may be requested by the Required Lenders in accordance with
Section 9; provided, however, that unless and until Agent has received any such request, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event
of Default as it shall deem advisable. 
  

	 	16.6.	Credit Decision. 

  
 Each Lender acknowledges that none of the Agent-Related Persons has made any representation or warranty to it, and that no act by Agent
hereinafter taken, including any review of the affairs of Companies and their Subsidiaries or Affiliates, shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Lender. Each Lender represents to Agent that it
has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial
and other condition and creditworthiness of Companies and any other Person (other than the Lender Group) party to a Loan Document, and all applicable bank regulatory laws relating to the transactions contemplated hereby, and made its own decision to
enter into this Agreement and to extend credit to Borrowers. Each Lender also represents that it will, independently and without reliance upon any Agent-Related Person and based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and creditworthiness of Companies and any other Person (other than the Lender Group) party to a Loan Document. Except for notices, reports, and other documents expressly herein required
to be furnished to the Lenders by Agent, Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or
creditworthiness of Borrowers and any other Person party to a Loan Document that may come into the possession of any of the Agent-Related Persons. 
  

 -91- 

	 	16.7.	Costs and Expenses; Indemnification. 

  
 Agent may incur and pay Lender Group Expenses to the extent Agent reasonably deems necessary or appropriate for the performance and
fulfillment of its functions, powers, and obligations pursuant to the Loan Documents, including court costs, reasonable attorneys fees and expenses, costs of collection by outside collection agencies and auctioneer fees and costs of security guards
or insurance premiums paid to maintain the Collateral, whether or not Companies are obligated to reimburse Agent or Lenders for such expenses pursuant to the Loan Agreement or otherwise. Agent is authorized and directed to deduct and retain
sufficient amounts from Collections received by Agent to reimburse Agent for such out-of-pocket costs and expenses prior to the distribution of any amounts to Lenders. In the event Agent is not reimbursed for such costs and expenses from Collections
received by Agent, each Lender hereby agrees that it is and shall be obligated to pay to or reimburse Agent for the amount of such Lender’s Pro Rata Share thereof. Whether or not the transactions contemplated hereby are consummated, the Lenders
shall indemnify upon demand the Agent-Related Persons (to the extent not reimbursed by or on behalf of Companies and without limiting the obligation of Companies to do so), according to their Pro Rata Shares, from and against any and all Indemnified
Liabilities; provided, however, that no Lender shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified Liabilities resulting solely from such Person’s gross negligence or willful misconduct
nor shall any Lender be liable for the obligations of any Defaulting Lender in failing to make an Advance or other extension of credit hereunder. Without limitation of the foregoing, each Lender shall reimburse Agent upon demand for such
Lender’s ratable share of any costs or out-of-pocket expenses (including attorneys fees and expenses) incurred by Agent in connection with the preparation, execution, delivery, administration, modification, amendment, or enforcement (whether
through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that Agent is not
reimbursed for such expenses by or on behalf of Companies. The undertaking in this Section shall survive the payment of all Obligations hereunder and the resignation or replacement of Agent. 
  

	 	16.8.	Agent in Individual Capacity. 

  
 Foothill and its Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests
in, and generally engage in any kind of banking, trust, financial advisory, underwriting, or other business with Companies and their Subsidiaries and Affiliates and any other Person (other than the Lender Group) party to any Loan Documents as though
Foothill were not Agent hereunder, and, in each case, without notice to or consent of the other members of the Lender Group. The other members of the Lender Group acknowledge that, pursuant to such activities, Foothill or its Affiliates may receive
information regarding Companies or their Affiliates and any other Person (other than the Lender Group) party to any Loan Documents that is subject to confidentiality obligations in favor of Companies or such other Person and that prohibit the
disclosure of such information to the Lenders, and the Lenders acknowledge that, in such circumstances (and in the absence of a waiver of such confidentiality obligations, which 

  

 -92- 

 
waiver Agent will use its reasonable best efforts to obtain), Agent shall not be under any obligation to provide such information to them. The terms
“Lender” and “Lenders” include Foothill in its individual capacity. 
  

	 	16.9.	Successor Agent. 

  
 Agent may resign as Agent upon 45 days notice to the Lenders. If Agent resigns under this Agreement, the Required Lenders shall appoint a
successor Agent for the Lenders. If no successor Agent is appointed prior to the effective date of the resignation of Agent, Agent may appoint, after consulting with the Lenders, a successor Agent. If Agent has materially breached or failed to
perform any material provision of this Agreement or of applicable law, the Required Lenders may agree in writing to remove and replace Agent with a successor Agent from among the Lenders. In any such event, upon the acceptance of its appointment as
successor Agent hereunder, such successor Agent shall succeed to all the rights, powers, and duties of the retiring Agent and the term “Agent” shall mean such successor Agent and the retiring Agent’s appointment, powers, and duties as
Agent shall be terminated. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Section 16 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this
Agreement. If no successor Agent has accepted appointment as Agent by the date which is 45 days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall nevertheless thereupon become effective and the
Lenders shall perform all of the duties of Agent hereunder until such time, if any, as the Lenders appoint a successor Agent as provided for above. 
  

	 	16.10.	 Lender in Individual Capacity. 

  
 Any Lender and its respective Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire
equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with Companies and their Subsidiaries and Affiliates and any other Person (other than the Lender Group) party to any Loan
Documents as though such Lender were not a Lender hereunder without notice to or consent of the other members of the Lender Group. The other members of the Lender Group acknowledge that, pursuant to such activities, such Lender and its respective
Affiliates may receive information regarding Companies or their Affiliates and any other Person (other than the Lender Group) party to any Loan Documents that is subject to confidentiality obligations in favor of Companies or such other Person and
that prohibit the disclosure of such information to the Lenders, and the Lenders acknowledge that, in such circumstances (and in the absence of a waiver of such confidentiality obligations, which waiver such Lender will use its reasonable best
efforts to obtain), such Lender not shall be under any obligation to provide such information to them. With respect to the Swing Loans and Agent Advances, Swing Lender shall have the same rights and powers under this Agreement as any other Lender
and may exercise the same as though it were not the sub-agent of the Agent. 
  

 -93- 

	 	16.11. 	Withholding Taxes. 

  
 (a) If any Lender is a “foreign corporation, partnership or trust” within the meaning of the IRC and such Lender claims
exemption from, or a reduction of, U.S. withholding tax under Sections 1441 or 1442 of the IRC, such Lender agrees with and in favor of Agent and Companies, to deliver to Agent and Administrative Borrower: 
  
 (i) if such Lender claims an exemption from withholding tax
pursuant to its portfolio interest exception, (a) a statement of the Lender, signed under penalty of perjury, that it is not a (i) a “bank” as described in Section 881(c)(3)(A) of the IRC, (ii) a 10% shareholder (within
the meaning of Section 881(c)(3)(B) of the IRC), or (iii) a controlled foreign corporation described in Section 881(c)(3)(C) of the IRC, and (B) a properly completed IRS Form W-8BEN, before the first payment of any interest under
this Agreement and at any other time reasonably requested by Agent or Administrative Borrower; 
  
 (ii) if such Lender claims an exemption from, or a reduction of, withholding tax under a United States tax treaty, properly completed IRS
Form W-8BEN before the first payment of any interest under this Agreement and at any other time reasonably requested by Agent or Administrative Borrower; 
  
 (iii) if such Lender claims that interest paid under this Agreement is exempt from United States withholding tax because it is effectively
connected with a United States trade or business of such Lender, two properly completed and executed copies of IRS Form W-8ECI before the first payment of any interest is due under this Agreement and at any other time reasonably requested by Agent
or Administrative Borrower; 
  
 (iv) such other
form or forms as may be required under the IRC or other laws of the United States as a condition to exemption from, or reduction of, United States withholding tax. 
  
 Such Lender agrees promptly to notify Agent and Administrative Borrower of any change in circumstances which would modify or render invalid
any claimed exemption or reduction. 
  
 (b) If
any Lender claims exemption from, or reduction of, withholding tax under a United States tax treaty by providing IRS Form W-8BEN and such Lender sells, assigns, grants a participation in, or otherwise transfers all or part of the Obligations of
Companies to such Lender, such Lender agrees to notify Agent of the percentage amount in which it is no longer the beneficial owner of Obligations of Companies to such Lender. To the extent of such percentage amount, Agent will treat such
Lender’s IRS Form W-8BEN as no longer valid. 
  
 (c) If any Lender is entitled to a reduction in the applicable withholding tax, Agent may withhold from any interest payment to such Lender an amount equivalent to the applicable withholding tax after taking into account such reduction. If
the forms or other 

  

 -94- 

 
documentation required by subsection (a) of this Section are not delivered to Agent, then Agent may withhold from any interest payment to such Lender
not providing such forms or other documentation an amount equivalent to the applicable withholding tax. 
  
 (d) If the IRS or any other Governmental Authority of the United States or other jurisdiction asserts a claim that Agent did not properly
withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered, was not properly executed, or because such Lender failed to notify Agent of a change in circumstances which rendered the exemption
from, or reduction of, withholding tax ineffective, or for any other reason) such Lender shall indemnify and hold Agent harmless for all amounts paid, directly or indirectly, by Agent as tax or otherwise, including penalties and interest, and
including any taxes imposed by any jurisdiction on the amounts payable to Agent under this Section, together with all costs and expenses (including attorneys fees and expenses). The obligation of the Lenders under this subsection shall survive the
payment of all Obligations and the resignation or replacement of Agent. 
  
 (e) All payments made by Companies hereunder or under any note or other Loan Document will be made without setoff, counterclaim, or other defense, except as required by applicable law other than for Taxes (as defined
below). All such payments will be made free and clear of, and without deduction or withholding for, any present or future taxes, levies, imposts, duties, fees, assessments or other charges of whatever nature now or hereafter imposed by any
jurisdiction (other than the United States) or by any political subdivision or taxing authority thereof or therein (other than of the United States) with respect to such payments (but excluding, any tax imposed by any jurisdiction or by any
political subdivision or taxing authority thereof or therein (i) measured by or based on the net income or net profits of a Lender, or (ii) to the extent that such tax results from a change in the circumstances of the Lender, including a
change in the residence, place of organization, or principal place of business of the Lender, or a change in the branch or lending office of the Lender participating in the transactions set forth herein) and all interest, penalties or similar
liabilities with respect thereto (all such non-excluded taxes, levies, imposts, duties, fees, assessments or other charges being referred to collectively as “Taxes”). If any Taxes are so levied or imposed, each Company agrees to pay
the full amount of such Taxes, and such additional amounts as may be necessary so that every payment of all amounts due under this Agreement or under any note, including any amount paid pursuant to this Section 16.11(e) after withholding
or deduction for or on account of any Taxes, will not be less than the amount provided for herein; provided, however, that Companies shall not be required to increase any such amounts payable to Agent or any Lender (i) that is not
organized under the laws of the United States, if such Person fails to comply with the other requirements of this Section 16.11, or (ii) if the increase in such amount payable results from Agent’s or such Lender’s own
willful misconduct or gross negligence. Companies will furnish to Agent as promptly as possible after the date the payment of any Taxes is due pursuant to applicable law certified copies of tax receipts evidencing such payment by Companies.

  

 -95- 

	 	16.12. 	Collateral Matters. 

  
 (a) The Lenders hereby irrevocably authorize Agent, at its option and in its sole discretion, to release any Lien on any Collateral
(i) upon the termination of the Commitments and payment and satisfaction in full by Companies of all Obligations, (ii) constituting property being sold or disposed of if a release is required or desirable in connection therewith and if
Administrative Borrower certifies to Agent that the sale or disposition is permitted under Section 7.4 of this Agreement or the other Loan Documents (and Agent may rely conclusively on any such certificate, without further inquiry),
(iii) constituting property in which no Company owned any interest at the time the security interest was granted or at any time thereafter, or (iv) constituting property leased to a Company under a lease that has expired or is terminated
in a transaction permitted under this Agreement. Except as provided above, Agent will not execute and deliver a release of any Lien on any Collateral without the prior written authorization of (y) if the release is of all or substantially all
of the Collateral, all of the Lenders, or (z) otherwise, the Required Lenders. Upon request by Agent or Administrative Borrower at any time, the Lenders will confirm in writing Agent’s authority to release any such Liens on particular
types or items of Collateral pursuant to this Section 16.12; provided, however, that (1) Agent shall not be required to execute any document necessary to evidence such release on terms that, in Agent’s opinion,
would expose Agent to liability or create any obligation or entail any consequence other than the release of such Lien without recourse, representation, or warranty, and (2) such release shall not in any manner discharge, affect, or impair the
Obligations or any Liens (other than those expressly being released) upon (or obligations of Companies in respect of) all interests retained by Companies, including, the proceeds of any sale, all of which shall continue to constitute part of the
Collateral. 
  
 (b) Agent shall have no
obligation whatsoever to any of the Lenders to assure that the Collateral exists or is owned by Companies or is cared for, protected, or insured or has been encumbered, or that the Agent’s Liens have been properly or sufficiently or lawfully
created, perfected, protected, or enforced or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities and
powers granted or available to Agent pursuant to any of the Loan Documents, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, subject to the terms and conditions contained herein, Agent
may act in any manner it may deem appropriate, in its sole discretion given Agent’s own interest in the Collateral in its capacity as one of the Lenders and that Agent shall have no other duty or liability whatsoever to any Lender as to any of
the foregoing, except as otherwise provided herein. 
  

	 	16.13. 	Restrictions on Actions by Lenders; Sharing of Payments. 

  
 (a) Each of the Lenders agrees that it shall not, without the express consent of Agent, and that it shall, to the extent it is lawfully
entitled to do so, upon the request of Agent, set off against the Obligations, any amounts owing by such Lender to Companies or any deposit accounts of Companies now or hereafter maintained with such Lender. Each of the Lenders further agrees that
it shall not, unless specifically requested to do so by Agent, 

  

 -96- 

 
take or cause to be taken any action, including, the commencement of any legal or equitable proceedings, to foreclose any Lien on, or otherwise enforce any
security interest in, any of the Collateral the purpose of which is, or could be, to give such Lender any preference or priority against the other Lenders with respect to the Collateral. 
  
 (b) If, at any time or times any Lender shall receive (i) by payment, foreclosure, setoff, or
otherwise, any proceeds of Collateral or any payments with respect to the Obligations arising under, or relating to, this Agreement or the other Loan Documents, except for any such proceeds or payments received by such Lender from Agent pursuant to
the terms of this Agreement, or (ii) payments from Agent in excess of such Lender’s ratable portion of all such distributions by Agent, such Lender promptly shall (1) turn the same over to Agent, in kind, and with such endorsements as
may be required to negotiate the same to Agent, or in immediately available funds, as applicable, for the account of all of the Lenders and for application to the Obligations in accordance with the applicable provisions of this Agreement, or
(2) purchase, without recourse or warranty, an undivided interest and participation in the Obligations owed to the other Lenders so that such excess payment received shall be applied ratably as among the Lenders in accordance with their Pro
Rata Shares; provided, however, that if all or part of such excess payment received by the purchasing party is thereafter recovered from it, those purchases of participations shall be rescinded in whole or in part, as applicable, and the applicable
portion of the purchase price paid therefor shall be returned to such purchasing party, but without interest except to the extent that such purchasing party is required to pay interest in connection with the recovery of the excess payment.

  

	 	16.14. 	Agency for Perfection. 

  
 Agent hereby appoints each other Lender as its agent (and each Lender hereby accepts such appointment) for the purpose of perfecting the
Agent’s Liens in assets which, in accordance with Article 9 of the UCC can be perfected only by possession. Should any Lender obtain possession of any such Collateral, such Lender shall notify Agent thereof, and, promptly upon Agent’s
request therefor shall deliver such Collateral to Agent or in accordance with Agent’s instructions. 
  

	 	16.15. 	Payments by Agent to the Lenders. 

  
 All payments to be made by Agent to the Lenders shall be made by bank wire transfer or internal transfer of immediately available funds
pursuant to such wire transfer instructions as each party may designate for itself by written notice to Agent. Concurrently with each such payment, Agent shall identify whether such payment (or any portion thereof) represents principal, premium, or
interest of the Obligations. 
  

	 	16.16. 	Concerning the Collateral and Related Loan Documents. 

  
 Each member of the Lender Group authorizes and directs Agent to enter into this Agreement and the other Loan Documents relating to the
Collateral, for the benefit of the Lender Group. Each member of the Lender Group agrees that any action taken by Agent in 

  

 -97- 

 
accordance with the terms of this Agreement or the other Loan Documents relating to the Collateral and the exercise by Agent of its powers set forth therein
or herein, together with such other powers that are reasonably incidental thereto, shall be binding upon all of the Lenders. 
  

	 	16.17. 	Field Audits and Examination Reports; Confidentiality; Disclaimers by Lenders; Other Reports and Information. 

  
 By becoming a party to this Agreement, each Lender:

  
 (a) is deemed to have requested that Agent
furnish such Lender, promptly after it becomes available, a copy of each field audit or examination report (each a “Report” and collectively, “Reports”) prepared by Agent, and Agent shall so furnish each Lender with
such Reports, 
  
 (b) expressly agrees and
acknowledges that Agent does not (i) make any representation or warranty as to the accuracy of any Report, and (ii) shall not be liable for any information contained in any Report, 
  
 (c) expressly agrees and acknowledges that the Reports are
not comprehensive audits or examinations, that Agent or other party performing any audit or examination will inspect only specific information regarding Companies and will rely significantly upon the Books, as well as on representations of
Companies’ personnel, 
  
 (d) agrees to keep
all Reports and other material, non-public information regarding Companies and their Subsidiaries and their operations, assets, and existing and contemplated business plans in a confidential manner; it being understood and agreed by Companies that
in any event such Lender may make disclosures (a) to counsel for and other advisors, accountants, and auditors to such Lender, (b) reasonably required by any bona fide potential or actual Assignee or Participant in connection with
any contemplated or actual assignment or transfer by such Lender of an interest herein or any participation interest in such Lender’s rights hereunder, (c) of information that has become public by disclosures made by Persons other than
such Lender, its Affiliates, assignees, transferees, or Participants, or (d) as required or requested by any court, governmental or administrative agency, pursuant to any subpoena or other legal process, or by any law, statute, regulation, or
court order; provided, however, that, unless prohibited by applicable law, statute, regulation, or court order, such Lender shall notify Administrative Borrower of any request by any court, governmental or administrative agency, or
pursuant to any subpoena or other legal process for disclosure of any such non-public material information concurrent with, or where practicable, prior to the disclosure thereof, and 
  
 (e) without limiting the generality of any other indemnification provision contained in this Agreement,
agrees: (i) to hold Agent and any such other Lender preparing a Report harmless from any action the indemnifying Lender may take or conclusion the indemnifying Lender may reach or draw from any Report in connection with any loans or other
credit accommodations that the indemnifying Lender has made or may make to 

  

 -98- 

 
Companies, or the indemnifying Lender’s participation in, or the indemnifying Lender’s purchase of, a loan or loans of Companies; and (ii) to
pay and protect, and indemnify, defend and hold Agent, and any such other Lender preparing a Report harmless from and against, the claims, actions, proceedings, damages, costs, expenses, and other amounts (including, attorneys fees and costs)
incurred by Agent and any such other Lender preparing a Report as the direct or indirect result of any third parties who might obtain all or part of any Report through the indemnifying Lender. 
  
 In addition to the foregoing: (x) any Lender may from time to time
request of Agent in writing that Agent provide to such Lender a copy of any report or document provided by Companies to Agent that has not been contemporaneously provided by Companies to such Lender, and, upon receipt of such request, Agent shall
provide a copy of same to such Lender, (y) to the extent that Agent is entitled, under any provision of the Loan Documents, to request additional reports or information from Companies, any Lender may, from time to time, reasonably request Agent
to exercise such right as specified in such Lender’s notice to Agent, whereupon Agent promptly shall request of Administrative Borrower the additional reports or information reasonably specified by such Lender, and, upon receipt thereof from
Administrative Borrower, Agent promptly shall provide a copy of same to such Lender, and (z) any time that Agent renders to Administrative Borrower a statement regarding the Loan Account, Agent shall send a copy of such statement to each
Lender. 
  

	 	16.18. 	Several Obligations; No Liability. 

  
 Notwithstanding that certain of the Loan Documents now or hereafter may have been or will be executed only by or in favor of Agent in its
capacity as such, and not by or in favor of the Lenders, any and all obligations on the part of Agent (if any) to make any credit available hereunder shall constitute the several (and not joint) obligations of the respective Lenders on a ratable
basis, according to their respective Commitments, to make an amount of such credit not to exceed, in principal amount, at any one time outstanding, the amount of their respective Commitments. Nothing contained herein shall confer upon any Lender any
interest in, or subject any Lender to any liability for, or in respect of, the business, assets, profits, losses, or liabilities of any other Lender. Each Lender shall be solely responsible for notifying its Participants of any matters relating to
the Loan Documents to the extent any such notice may be required, and no Lender shall have any obligation, duty, or liability to any Participant of any other Lender. Except as provided in Section 16.7, no member of the Lender Group shall
have any liability for the acts or any other member of the Lender Group. No Lender shall be responsible to any Company or any other Person for any failure by any other Lender to fulfill its obligations to make credit available hereunder, nor to
advance for it or on its behalf in connection with its Commitment, nor to take any other action on its behalf hereunder or in connection with the financing contemplated herein. 
  

	 	16.19. 	Legal Representation of Agent. 

  
 In connection with the negotiation, drafting, and execution of this Agreement and the other Loan Documents, or in connection with future
legal representation relating to 

  

 -99- 

 
loan administration, amendments, modifications, waivers, or enforcement of remedies, Goldberg, Kohn, Bell, Black, Rosenbloom & Moritz, Ltd.
(“GK”) only has represented and only shall represent Foothill in its capacity as Agent and as a Lender. Each other Lender hereby acknowledges that GK does not represent it in connection with any such matters. 
  

	17.	GENERAL PROVISIONS. 

  

	 	17.1.	 Effectiveness. 

  
 This Agreement shall be binding and deemed effective when executed by Companies, Agent, and each Lender whose signature is provided for on
the signature pages hereof. 
  

	 	17.2.	 Section Headings. 

  
 Headings and numbers have been set forth herein for convenience only. Unless the contrary is compelled by the context, everything
contained in each Section applies equally to this entire Agreement. 
  

	 	17.3.	 Interpretation. 

  
 Neither this Agreement nor any uncertainty or ambiguity herein shall be construed or resolved against the Lender Group or Companies,
whether under any rule of construction or otherwise. On the contrary, this Agreement has been reviewed by all parties and shall be construed and interpreted according to the ordinary meaning of the words used so as to accomplish fairly the purposes
and intentions of all parties hereto. 
  

	 	17.4.	 Severability of Provisions. 

  
 Each provision of this Agreement shall be severable from every other provision of this Agreement for the purpose of determining the legal
enforceability of any specific provision. 
  

	 	17.5.	 Amendments in Writing. 

  
 This Agreement only can be amended by a writing in accordance with Section 15.1. 
  

	 	17.6.	 Counterparts; Telefacsimile Execution. 

  
 This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when
executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement. Delivery of an executed counterpart of this Agreement by telefacsimile shall be equally as effective
as delivery of an original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by telefacsimile also shall deliver an original executed counterpart of this Agreement but the 

  

 -100- 

 
failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement. The foregoing shall
apply to each other Loan Document mutatis mutandis. 
  

	 	17.7.	 Revival and Reinstatement of Obligations. 

  
 If the incurrence or payment of the Obligations by any Company or the transfer to the Lender Group of any property should for any reason
subsequently be declared to be void or voidable under any state or federal law relating to creditors’ rights, including provisions of the Bankruptcy Code relating to fraudulent conveyances, preferences, or other voidable or recoverable payments
of money or transfers of property (collectively, a “Voidable Transfer”), and if the Lender Group is required to repay or restore, in whole or in part, any such Voidable Transfer, or elects to do so upon the reasonable advice of its
counsel, then, as to any such Voidable Transfer, or the amount thereof that the Lender Group is required or elects to repay or restore, and as to all reasonable costs, expenses, and attorneys fees of the Lender Group related thereto, the liability
of Companies automatically shall be revived, reinstated, and restored and shall exist as though such Voidable Transfer had never been made. 
  

	 	17.8. 	Integration. 

  
 This Agreement, together with the other Loan Documents, reflects the entire understanding of the parties with respect to the transactions
contemplated hereby and shall not be contradicted or qualified by any other agreement, oral or written, before the date hereof. 
  

	 	17.9.	 Parent as Agent for Companies. 

  
 Each Company hereby irrevocably appoints Parent as the borrowing agent and attorney-in-fact for all Companies (the “Administrative
Borrower”) which appointment shall remain in full force and effect unless and until Agent shall have received prior written notice signed by each Company that such appointment has been revoked and that another Company has been appointed
Administrative Borrower. Each Company hereby irrevocably appoints and authorizes the Administrative Borrower (i) to provide Agent with all notices with respect to Advances and Letters of Credit obtained for the benefit of any Borrower and all
other notices and instructions under this Agreement and (ii) to take such action as the Administrative Borrower deems appropriate on its behalf to obtain Advances and Letters of Credit and to exercise such other powers as are reasonably
incidental thereto to carry out the purposes of this Agreement. It is understood that the handling of the Loan Account and Collateral of Companies in a combined fashion, as more fully set forth herein, is done solely as an accommodation to Companies
in order to utilize the collective borrowing powers of Companies in the most efficient and economical manner and at their request, and that Lender Group shall not incur liability to any Company as a result hereof. Each Company expects to derive
benefit, directly or indirectly, from the handling of the Loan Account and the Collateral in a combined fashion since the successful operation of each Company is dependent on the continued successful performance of the integrated group. To induce
the 

  

 -101- 

 
Lender Group to do so, and in consideration thereof, each Company hereby jointly and severally agrees to indemnify each member of the Lender Group and hold
each member of the Lender Group harmless against any and all liability, expense, loss or claim of damage or injury, made against the Lender Group by any Company or by any third party whosoever, arising from or incurred by reason of (a) the
handling of the Loan Account and Collateral of Companies as herein provided, (b) the Lender Group’s relying on any instructions of the Administrative Borrower, or (c) any other action taken by the Lender Group hereunder or under the
other Loan Documents, except that Companies will have no liability to the relevant Agent-Related Person or Lender-Related Person under this Section 17.9 with respect to any liability that has been finally determined by a court of
competent jurisdiction to have resulted solely from the gross negligence or willful misconduct of such Agent-Related Person or Lender-Related Person, as the case may be.

 FORM OF ASSIGNMENT AND ACCEPTANCE AGREEMENT 
  
 This ASSIGNMENT AND ACCEPTANCE AGREEMENT (“Assignment Agreement”) is entered into as of
                                        
between
                                        
(“Assignor”) and
                                        
(“Assignee”). Reference is made to the Agreement described in Item 2 of Annex I annexed hereto (the “Loan Agreement”). Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to
them in the Loan Agreement. 
  
 1. In accordance with the terms
and conditions of Section 14 of the Loan Agreement, the Assignor hereby sells and assigns to the Assignee, and the Assignee hereby purchases and assumes from the Assignor, that interest in and to the Assignor’s rights and obligations under
the Loan Documents as of the date hereof with respect to the Obligations owing to the Assignor, and Assignor’s portion of the Total Commitments and the Revolver Commitments all as specified in Item 4.b and Item 4.c of
Annex I. After giving effect to such sale and assignments, the Assignee’s portion of the Total Commitments and the Revolver Commitments will be as set forth in Item 4.b of Annex I. After giving effect to such sale and
assignment the Assignor’s amount and portion of the Total Commitments and the Revolver Commitments will be as set forth in Item 4.d and Item 4.e of Annex I. 
  
 2. The Assignor (a) represents and warrants that it is the legal and beneficial owner of the interest being assigned by
it hereunder and that such interest is free and clear of any adverse claim; (b) makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with the
Loan Documents or the execution, legality, validity, enforceability, genuineness, sufficiency or value of the Loan Documents or any other instrument or document furnished pursuant thereto; and (c) makes no representation or warranty and assumes
no responsibility with respect to the financial condition of Borrowers or the performance or observance by Borrowers of any of their obligations under the Loan Documents or any other instrument or document furnished pursuant thereto.

that it is eligible as an assignee under the terms of the Loan Agreement; (d) appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to Agent by the

States withholding taxes with respect to all payments to be made to the Assignee under the Loan Agreement or such other documents as are necessary to indicate that all such payments are subject to such rates at a rate reduced by an applicable tax
treaty.] 
  
 4. Following the execution of this Assignment
Agreement by the Assignor and Assignee, it will be delivered by the Assignor to the Agent for recording by the Agent. The effective date of this Assignment (the “Settlement Date”) shall be the later of (a) the date of the execution

Agreement and the other Loan Documents. The Assignor and Assignee shall make all appropriate adjustments in payments under the Loan Agreement and the other Loan Documents for periods prior to the Settlement Date directly between themselves on the

	To:	Foothill Capital Corporation, as Agent 

 under the
below-referenced Loan Agreement 
 2450 Colorado Avenue 
 Suite 3000 West 
 Santa Monica, CA 90404 
 Attn: Business Finance Division Manager 
  

	 	Re:	Compliance Certificate dated                     

  
 Ladies and Gentlemen: 
  
 Reference is made to that certain Loan and Security Agreement, dated as of
October         , 2002 (the “Loan Agreement”), among Telos Corporation, a Maryland corporation (“Telos”), Xacta Corporation, a Delaware corporation (“Xacta”; Telos and
Xacta are each referred to hereinafter individually as a “Borrower” and collectively as “Borrowers”), certain Credit Parties from time to time party thereto, the lenders signatory thereto (the “Lenders”), and Foothill
Capital Corporation, a California corporation, as the arranger and administrative agent for the Lenders (“Agent”). Capitalized terms used in this Compliance Certificate have the meanings set forth in the Loan Agreement unless specifically
defined herein. 
  
 Pursuant to Section 6.3 of the
Loan Agreement, the undersigned officer of Borrower hereby certifies that: 
  
 1. The financial information of Parent and its Subsidiaries furnished in Schedule 1 attached hereto, has been prepared in accordance with GAAP (except for year-end adjustments and the lack of footnotes, in the

 Affiliated Transactions 
  

	a)	Telos has a continuing contractual obligation to make advances on behalf of its joint venture partner, Telos OK, so as to fulfill its responsibility to provide professional
services, which include, but are not limited to, insurance and other professional matters covered by its Service Agreement. At any one point in time Telos may have to advance up to $50,000 on behalf of Telos OK, which is promptly thereafter
reimbursed, provided that the aggregate amounts advanced and outstanding on behalf of Telos OK shall at no time exceed $50,000. Accordingly, such advances shall not be considered as inconsistent with the intent of §7.14 and thereby specifically
acknowledged by lender as excluded from any such prohibition included therein. 

  

	b)	Telos has a continuing contractual obligation to provide professional and other services to Enterworks. Such services include, but are not limited to, office rental, security,
facilities related matters, and professional services. Over the course of the past three years, payment by Enterworks to Telos has taken many forms, which include cash and various forms of notes, as have been set forth in detail in the relevant
public disclosure including SEC form 10K’s and 10Q’s which have been presented to lender. The annual amount of such services is approximately $ 1,200,000. Accordingly, such services and related payment methods shall not be considered
inconsistent with the intent of §7.14 and thereby specifically acknowledged by lender as excluded from any such prohibition included therein.

 THIS SUBORDINATION AGREEMENT (“Agreement”),
dated as of October 11, 2002, entered into between Foothill Capital Corporation, as agent (“Agent”) for itself and for the Lenders (defined below), each of the parties identified on the signature pages hereto as a “Subordinated

described below (the “Trustee”; Trustee and each Subordinated Noteholder are collectively, the “Creditors” and each, a “Creditor”). 
  
 W I T N E S S E T H 
  
 WHEREAS, Subordinated Noteholders are financially interested in Telos
Corporation, a Maryland corporation (“Company”), in that Company is indebted to Subordinated Noteholders with respect to (i) those certain Series B Senior Subordinated Secured Notes due May 23, 2003 in the aggregate current
principal amount of Five Million Five Hundred Thirty-Seven Thousand Eight Hundred Seventy and 00/100 Dollars ($5,537,870.00) (the “Series B Subordinated Notes”), copies of which are attached hereto as Exhibit A-l and (ii) those
certain Series C Senior Subordinated Unsecured Notes due May 23, 2003 in the aggregate current principal amount of Two Million Six Hundred Forty Thousand Six Hundred Eighty-Four and 00/100 Dollars ($2,640,684.00) (the “Series C
Subordinated Notes” and, together with the Series B Subordinated Notes, the “Subordinated Notes”), copies of which are attached hereto as Exhibit A-2; 
  
 WHEREAS, the obligations of Company in respect of the Series B Subordinated Notes are secured by liens on certain assets of
Company specified on Exhibit B attached hereto (the “Series B Collateral”) pursuant to the terms of the collateral documentation attached hereto as Exhibit C (the “Series B Collateral Documents”); 
  
 WHEREAS, the Trustee has been designated by the holders of the Series B
Subordinated Notes as collateral trustee with respect to the Series B Collateral pursuant to the terms of the Series B Collateral Documents; 
  
 WHEREAS, Company is indebted to Agent and Lenders in connection with the advances of monies and other financial arrangements by Agent and Lenders to
Company; and 
  
 WHEREAS, such advances of monies and other
financial arrangements are evidenced by various agreements, instruments and documents, including, without limitation, that certain Loan and Security Agreement on or about even date herewith between Company, certain financial institutions from time
to time party thereto as lenders (“Lenders”) and Agent (the “Loan Agreement”); 

 NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged by Creditors, Creditors and the Trustee hereby agree with Agent as hereinafter set forth. 
  
 1. Standby; Subordination; Subrogation. No Creditor will ask, demand, sue for, take or, except as provided in Section 2 below, receive from
Company or any other party, by setoff or in any other manner: 
  
 (a) The whole or any part of any indebtedness, obligations and liabilities which may now or hereafter be owing by Company, or any successor or assign of Company, including, without limitation, a receiver, trustee or debtor in possession
(the term “Company” hereinafter shall include any such successor and assign of Company), to such Creditor in respect of the Subordinated Notes and the Series B Collateral Documents (all such indebtedness, obligations and liabilities being
hereinafter referred to as the “Subordinated Debt”); or 
  
 (b) Any security for any of the foregoing (other than the Series B Collateral); 
  
 unless and until all obligations, liabilities, and indebtedness of Company to Agent and Lenders, whether now existing or hereafter arising directly between Company and Agent or any Lender, or acquired outright,
conditionally or as collateral security from another by Agent or any Lender, shall have been fully paid and satisfied in cash with interest, including, without limitation, any interest accruing after the commencement of insolvency proceedings with
respect to Company, whether or not such interest is allowed as a claim in such proceeding (all such obligations, indebtedness and liabilities of Company to Agent and each Lender being hereinafter referred to as the “Senior Debt”) and all
financing arrangements between Company, Agent and Lenders have been terminated. All liens and security interests of each Creditor, whether now or hereafter arising and howsoever existing, in any assets of Company or any assets securing the Senior
Debt (including, without limitation, the Series B Collateral) shall be and hereby are subordinated to the rights and interests of Agent and Lenders in those assets irrespective of whether Agent’s liens and security interests have been
perfected, or the time or order of attachment or perfection of liens or security interests, or the time of filing or recording of financing statements, mortgages or other agreements or documents, or the time of giving or failure to give notice of
acquisition of purchase money or other security interests or liens; no Creditor shall have any right to possession of any such assets, to notify account debtors of Company or to foreclose upon or exercise any other right or remedy with respect to
any such assets, whether by judicial action or otherwise, unless and until all of the Senior Debt shall have been fully paid and satisfied in cash and all financing arrangements between Company, Agent and Lenders have been terminated. Each Creditor
also hereby agrees that, (i) the Senior Debt shall include all obligations, indebtedness and liabilities of Company to Agent and each Lender, notwithstanding the invalidity or unenforceability of all or any part of the Senior Debt, or any right
or power of Company or any other entity or individual to assert any claim or defense as to the invalidity or 

  

 -2- 

 
unenforceability of any such obligation, indebtedness or liability and no such claim or defense shall affect or impair the agreements and obligations of such
Creditor hereunder; and (ii) regardless of whether the Senior Debt is secured or unsecured, Agent and Lenders shall be subrogated for such Creditor with respect to such Creditor’s claims with respect to the Subordinated Debt against
Company and such Creditor’s rights, liens and security interests, if any, in any of Company’s assets (including, without limitation, the Series B Collateral) and the proceeds thereof until all of the Senior Debt shall have been fully paid
and satisfied in cash and all financing arrangements between Company, Agent and Lenders have been terminated. 
  
 2. Permitted Payments. Notwithstanding anything contained in Section 1 to the contrary, Subordinated Noteholders may receive, and Company may
pay, the following payments in respect to the Subordinated Notes: (a) an initial aggregate payment in an amount not to exceed $3,000,000 (such exact amount to be determined by Agent and based on Excess Availability (as defined in the Loan
Agreement) being at least $4,000,000 after giving effect to such initial aggregate payment) from the proceeds of the initial loans under the Loan Agreement to be applied to accrued interest and principal in respect of the Subordinated Notes; and
(b) at any time during the period after the later of March 1, 2003 and Agent’s receipt of Company’s December 31, 2002 audited financial statements certified by its independent certified public accountants and prior to
May 1, 2003, additional payments to be applied to accrued interest and principal in respect of the Subordinated Notes so long as (i) after giving effect for such payment, no Event of Default (as defined in the Loan Agreement) exists or
would be caused thereby, (ii) after giving effect to such payment, Excess Availability (as defined in the Loan Agreement) (calculated without deducting the Availability Block (as defined in the Loan Agreement)) is at least $4,000,000,
(iii) Excess Availability (calculated without deducting the Availability Block) is at least $4,000,000 for each of the thirty (30) days following such payment, and (iv) at least thirty (30) days prior to making such payment,
Agent shall have received Company’s projections, in form and substance satisfactory to Agent, demonstrating that Company will have satisfactory (as determined by Agent) capitalization, liquidity and availability for the twelve (12) month
period following such payment (collectively, the payments under (a) and (b), the “Permitted Payments”). Except as contemplated by Section 17 below, Company and Creditors hereby agree and understand that the terms of the
Subordinated Debt, the Subordinated Notes and the Series B Collateral Documents may not be modified or amended without Agent’s prior written consent. Notwithstanding anything contained in this Section 2 to the contrary, the aggregate
outstanding principal balance of the Subordinated Notes shall not at any time be less than $1,000. Company acknowledges and agrees that the failure to maintain Excess Availability of at least $4,000,000 at all times during the 30 day period
following a payment under clause (b) above shall constitute an Event of Default. 
  
 3. Subordinated Debt Owed Only to Creditors. Each Subordinated Noteholder warrants and represents (a) that such Subordinated Noteholder has not previously assigned or transferred any interest in the
Subordinated Debt, (b) that no other party owns an interest in the Subordinated Debt other than Subordinated Noteholders, (c) that the 

  

 -3- 

 
Subordinated Debt had not been guaranteed by any person and Company is the only obligor with respect to the Subordinated Debt and (d) that the entire
Subordinated Debt is owing only to Subordinated Noteholders and covenants that the entire Subordinated Debt shall continue to be owing only to Subordinated Noteholders unless assigned or transferred subject to the terms of this Agreement. No
Subordinated Noteholder or the Trustee will, without the prior written consent of Agent: (a) cancel, waive, forgive, or subordinate to any other indebtedness of Company (other than the Senior Debt), any of the Subordinated Debt or any rights in
respect thereof; (b) except for the Series B Collateral, take any collateral security for any of the Subordinated Debt; (c) take any guaranty from any person with respect to all or any portion of the Subordinated Debt; or
(d) commence, or join with any other creditor in commencing, any bankruptcy, reorganization or insolvency proceedings with respect to Company. 
  
 4. Priority of Agent and Lenders; Grant of Authority to Agent. In the event of any distribution, division or application, partial or complete,
voluntary or involuntary, by operation of law or otherwise, of all or any part of the assets of Company or the proceeds thereof to the creditors of Company or readjustment of the obligations and indebtedness of Company, whether by reason of
liquidation, bankruptcy, arrangement, receivership, assignment for the benefit of creditors or any other action or proceeding involving the readjustment of all or any part of the Subordinated Debt, or the application of the assets of Company to the
payment or liquidation thereof, or upon the dissolution, liquidation, cessation or other winding up of Company’s business, or upon the sale of all or substantially all of Company’s assets, then, and in any such event, (i) Agent, for
the benefit of itself and Lenders, shall be entitled to receive payment in cash in full of any and all of the Senior Debt then owing prior to the payment of all or any part of the Subordinated Debt and (ii) any payment or distribution of any
kind or character, whether in cash, securities or other property, which shall be payable or deliverable upon or with respect to any or all of the Subordinated Debt shall be paid or delivered directly to Agent for application on any of the Senior
Debt, due or not due, until such Senior Debt shall have first been fully paid and satisfied in cash. Agent is hereby irrevocably authorized and empowered, in its discretion, to make and present for and on behalf of any Creditor such proofs of claim
against Company on account of the Subordinated Debt as Agent may deem expedient or proper and to vote such proofs of claim in any such proceeding and to receive and collect any and all dividends or other payments or disbursements made thereon in
whatever form the same may be paid or issued and to apply the same on account of any of the Senior Debt. Each Creditor irrevocably authorizes and empowers Agent to demand, sue for, collect and receive each of the aforesaid payments and distributions
and give acquaintance therefor and to file claims and take such other actions, in Agent’s own name or in the name of such Creditor or otherwise, as Agent may deem necessary or advisable for the enforcement of this Agreement; and such Creditor
will execute and deliver to Agent such powers of attorney, assignments and other instruments or documents, including notes (together with such assignments or endorsements as Agent shall deem necessary or appropriate) as may be requested by Agent in
order to enable Agent to enforce any and all claims upon or with respect to any or all of the Subordinated Debt and to collect and receive any and all payments and distributions which 

  

 -4- 

 
may be payable or deliverable at any time upon or with respect to the Subordinated Debt, all for the benefit of Agent and Lenders. Following payment in full
of the Senior Debt in cash, Agent will remit to Creditors, to the extent of Creditors’ interest therein, all dividends or other payments or distributions paid to and held by Agent in excess of the Senior Debt. 
  
 5. Payments Received by Creditors; Consent to Sale; Allocation.

  
 (a) Except for Permitted Payments, should any payment,
distribution, security or instrument, or any proceeds thereof, be received by any Creditor upon or with respect to the Subordinated Debt prior to the satisfaction of all of the Senior Debt in cash and termination of all financing arrangements
between Company, Agent and Lenders, such Creditor shall receive and hold the same in trust, as trustee, for the benefit of Agent and Lenders and shall forthwith deliver the same to Agent in precisely the form received (except for the endorsement or
assignment by such Creditor where necessary), for application on any of the Senior Debt, due or not due, and, until so delivered, the same shall be held in trust by such Creditor as the property of Agent. In the event of the failure of any Creditor
to make any such endorsement or assignment to Agent, Agent, or any of its officers or employees, is hereby irrevocably authorized to make the same. 
  
 (b) In the event Company desires to dispose of any of the Collateral (as herein defined) and Agent consents to such disposition, each Creditor shall be
deemed to have consented to such disposition free and clear of any liens and security interests of such Creditor in such Collateral (including, without limitation, the Series B Collateral) and such Creditor agrees that any purchaser of any
Collateral may rely on this Agreement as evidence of such Creditor’s consent to such disposition free and clear of any liens and security interests of such Creditor in such Collateral (including, without limitation, the Series B Collateral).
Each Creditor agrees to execute such releases with respect to the Collateral (including, without limitation, the Series B Collateral) to be disposed of as Company or as Agent requests; provided, that (i) the failure of such Creditor to
execute such releases shall not affect the right of the purchaser of such Collateral (including, without limitation, the Series B Collateral) to rely on this Agreement and (ii) in furtherance of the foregoing, such Creditor hereby irrevocably
appoints Agent its attorney-in-fact, with full authority in the place and stead of such Creditor and in the name of such Creditor, to execute and deliver the releases which such Creditor may be required to deliver pursuant to this Section 5(b).
In the event any Creditor receives any proceeds of Collateral to which Agent is entitled under this Agreement, such Creditor shall hold such proceeds in trust and promptly remit such proceeds in the same form received to Agent unless the Senior Debt
has been paid in full in cash. 
  
 6. Instrument Legend;
Amendments. Any instrument or certificate evidencing any of the Subordinated Debt, or any portion thereof, will be inscribed with a legend conspicuously indicating that payment thereof is subordinated to the claims of Agent and Lenders pursuant
to the terms of this Agreement, and a copy thereof will be delivered to Agent. Any instrument or certificate evidencing any of the Subordinated Debt, or any portion thereof, which is hereafter executed by Company will, on the date thereof, be

  

 -5- 

 
inscribed with the aforesaid legend and a copy thereof will be delivered to Agent on the date of its execution or within five (5) business days
thereafter and the original thereof will be delivered as and when described hereinabove. Each Creditor hereby authorizes Agent to take such action as Agent deems appropriate to evidence the subordination effected hereunder, including without
limitation the filing by Agent on behalf of each Creditor of Uniform Commercial Code amendment statements that provide that the Series B Collateral in favor of Trustee has been subordinated to Agent. 
  
 7. Continuing Nature of Subordination; Subrogation. This Agreement
shall be irrevocable and shall continue to be effective (notwithstanding the insolvency, liquidation or dissolution of Company) until the Senior Debt shall have been paid in cash in full and all financing arrangements between Company, Agent and
Lenders have been terminated. This is a continuing agreement of subordination and Agent and Lenders may continue, at any time and without notice to any Creditor, to extend credit or other financial accommodations and loan monies to or for the
benefit of Company on the faith hereof. This Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Senior Debt is rescinded or must otherwise be returned by any holder of Senior Debt,
all as though such payment had not been made. Upon the payment in full in cash of all Senior Debt and termination of all financing arrangements between Company, Agent and Lenders, Creditors shall be subrogated to the extent of the payments or
distributions made to Agent, or otherwise applied to payment of, the Senior Debt pursuant to the provisions of this Agreement. 
  
 8. Additional Agreements Between Company, Agent and Lenders. Agent and each Lender may, at any time and from time to time, without notice to any
Creditor, enter into such agreement or agreements with Company as Agent or such Lender may deem proper, extending the time of payment of or renewing or otherwise altering, amending, modifying or supplementing the terms of the Loan Agreement, other
agreements, instruments and documents evidencing the Senior Debt or all or any of the Senior Debt or affecting the collateral or any guaranty underlying any or all of the Senior Debt, and may exchange, sell, release, surrender or otherwise deal with
any such security or guaranties, without in any way thereby impairing or affecting this Agreement. 
  
 9. Creditors’ Waivers. Each Creditor expressly waives all notice of (i) the existence or creation or nonpayment of all or any portion of
the Senior Debt and (ii) the acceptance by Agent and Lenders of the subordination and other provisions of this Agreement and all the notices not specifically required pursuant to the terms of this Agreement whatsoever and each Creditor
expressly waives reliance by Agent and Lenders upon the subordination and other agreements as herein provided. This Agreement shall remain valid and effective and the provisions of this Agreement shall apply to each Creditor and Agent regardless of
the validity, enforceability or priority of the Senior Debt or any liens securing the Senior Debt. Each Creditor agrees that neither Agent nor any Lender has made any warranties or representations with respect to the due execution, legality,
validity, completeness or enforceability of the Loan Agreement, or the collectability of the Senior 

  

 -6- 

 
Debt, that Agent and Lenders shall be entitled to manage and supervise their financial arrangements with Company without affecting the validity or
enforceability of this Agreement and without regard to the existence of any rights that such Creditor may now or hereafter have in or to any of the assets of Company, and that neither Agent nor any Lender shall have any liability to such Creditor
for, and waives any claim which such Creditor may now or hereafter have against, Agent or any Lender arising out of (i) any and all actions which Agent or any Lender takes or omits to take (including, without limitation, actions with respect to
the creation, perfection or continuation of liens or security interests in any existing or future collateral for the Senior Debt (the “Collateral”), actions with respect to the occurrence of an Event of Default (as defined in the Loan
Agreement), actions with respect to the foreclosure upon, sale, release, or depreciation of, or failure to realize upon, any of the Collateral and actions with respect to the collection of any claim for all or any part of the Senior Debt from any
account debtor, guarantor or any other party) with respect to the Loan Agreement or any other agreement related thereto or to the collection of the Senior Debt or the valuation, use, protection or release of the Collateral, (ii) Agent’s
election, in any proceeding instituted under Chapter 11 of Title 11 of the United States Code (11 U.S.C. § 101 et seq.) (the “Bankruptcy Code”), of the application of Section l l l l (b)(2) of the Bankruptcy Code and/or (iii) any
use of cash collateral under Section 363 of the Bankruptcy Code or any borrowing or grant of a security interest under Section 364 of the Bankruptcy Code by Company, as debtor in possession. In that regard, each Creditor agrees that
(A) if Company desires to use cash collateral under Section 363 of the Bankruptcy Code and Agent consents to such use, such Creditor will also consent to such use without asserting any objection of any kind (including an objection on the
grounds of failure to provide adequate protection for such Creditor’s junior lien on the Series B Collateral), and (B) if Company desires to obtain credit from Agent and Lenders under Section 364 of the Bankruptcy Code to be secured
by the Collateral, such Creditor will consent to such credit without asserting any objection of any kind (including an objection on the grounds of failure to provide adequate protection for such Creditor’s junior lien on the Series B
Collateral). Without limiting the generality of the foregoing, each Creditor waives the right to assert the doctrine of marshalling with respect to any of the Collateral, and consents and agrees that Agent may proceed against any or all of the
Collateral in such order as Agent shall determine in its sole discretion. 
  
 10. Agent’s Waivers. No waiver shall be deemed to be made by Agent of any of its rights hereunder, unless the same shall be in a writing, and each waiver, if any, shall be a waiver only with respect to the
specific instance involved and shall in no way impair the rights of Agent or any Lender or the obligations of Creditors to Agent and each Lender in any other respect at any other time. No delay on the part of Agent or any Lender in the exercise of
any right or remedy shall operate as a waiver thereof, and no single or partial exercise by Agent or any Lender of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy. 
  
 11. Information Concerning Financial Condition of Company. Each
Creditor hereby assumes responsibility for keeping itself informed of the financial condition 

  

 -7- 

 
of Company, any and all endorsers and any and all guarantors of the Senior Debt and/or the Subordinated Debt and of all other circumstances bearing upon the
risk of nonpayment of the Senior Debt and/or Subordinated Debt that diligent inquiry would reveal, and such Creditor hereby agrees that Agent shall have no duty to advise such Creditor of information known to Agent regarding such condition or any
such circumstances. In the event Agent, in its sole discretion, undertakes, at any time or from time to time, to provide any such information to any Creditor, Agent shall be under no obligation (i) to provide any such information to such
Creditor on any subsequent occasion or (ii) to undertake any investigation not a part of its regular business routine and shall be under no obligation to disclose any information which, pursuant to accepted or reasonable commercial finance
practices, Agent wishes to maintain confidential. Each Creditor hereby agrees that all payments received by Agent may be applied, reversed, and reapplied, in whole or in part, to any of the Senior Debt, without affecting the validity or
enforceability of this Agreement and assents to any extension or postponement of the time of payment of the Senior Debt or to any other indulgence with respect thereto, to any substitution, exchange or release of all or any of the Collateral and to
the addition or release of any other party or person primarily or secondarily liable therefor. 
  
 12. No Offset. In the event any Creditor at any time is indebted to Company, such Creditor hereby irrevocably agrees that such Creditor shall not deduct from or setoff against any amounts owing by such Creditor
to Company any amounts such Creditor claims are due to such Creditor with respect to the Subordinated Debt. 
  
 13. GOVERNING LAW; CONSENT TO JURISDICTION; WAIVERS. THIS AGREEMENT SHALL BE DEEMED TO HAVE BEEN MADE IN THE STATE OF ILLINOIS AND SHALL BE
INTERPRETED IN ACCORDANCE WITH THE INTERNAL LAWS OF ILLINOIS AND NOT THE CONFLICT OF LAWS RULES OF THE STATE OF ILLINOIS GOVERNING CONTRACTS TO BE PERFORMED ENTIRELY WITHIN SUCH STATE. EACH CREDITOR HEREBY AGREES TO THE EXCLUSIVE JURISDICTION OF ANY
STATE OR FEDERAL COURT LOCATED WITHIN THE COUNTY OF COOK, STATE OF ILLINOIS OR, AT THE SOLE OPTION OF AGENT, IN ANY OTHER COURT IN WHICH AGENT SHALL INITIATE LEGAL OR EQUITABLE PROCEEDINGS AND WHICH HAS SUBJECT MATTER JURISDICTION OVER THE MATTER IN
CONTROVERSY. EACH CREDITOR WAIVES ANY OBJECTION OF FORUM NON CONVENIENS AND VENUE. AGENT AND EACH CREDITOR EACH HEREBY WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO THIS AGREEMENT,
WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE. 
  
 14.
Section Titles; Gender; No Prejudice of Rights. The section titles contained in this Agreement are and shall be without substantive meaning or content of any kind whatsoever and are not a part of the agreement between the parties hereto. The
singular form of any word used in this Agreement shall include the plural form and the neuter form of any word used in this Agreement shall include the masculine and feminine forms, and vice 

  

 -8- 

 
versa. Agent shall not be prejudiced in its rights under this Agreement by any act or failure to act of Company or any Creditor, or any noncompliance of
Company or any Creditor with any agreement or obligation, regardless of any knowledge thereof which Agent may have or with which Agent may be charged; and no action of Agent permitted hereunder shall in any way affect or impair the rights of Agent
and the obligations of each Creditor under this Agreement.

 FOR VALUE RECEIVED, Telos Corporation, a Maryland corporation, with offices at 460 Herndon Parkway, Herndon, Virginia 22070

England, at such other offices or at such other place or places as the holder hereof may from time to time designate in writing, the principal sum of SEVEN HUNDRED NINE THOUSAND FOUR HUNDRED NINETY-SEVEN DOLLARS AND 49/100 ($709,497.49) on
October 1, 2000 together with interest on the principal amount hereof from time to time outstanding at the rate hereinafter provided until paid in full. 
  
 This is one of a series of the Company’s Notes known as its Series B Senior Subordinated Secured Notes Due October 1, 2000 (collectively

 I. GENERAL TERMS 

 
 1.1 Interest only shall be payable at the rate of fourteen percent
(14%) per annum, on the principal balance of this Note from time to time outstanding from and after the date hereof, and shall be due and payable quarterly, until the principal has been paid in full, on the first day of April, July, October,
and January in each year. Notwithstanding the foregoing, the rate of 

 
interest shall be increased to an amount necessary to result in a payment to the holder of fourteen percent (14%) per annum net of withholding for
United States Federal Income Taxes, it being contemplated that Borrower shall receive substantiation for Federal Income Tax purposes of circumstances supporting withholding at a rate no greater than seventeen and one-half percent (17 1/2%) of
interest hereunder. The first interest payment shall be due January 1, 1996 and shall include all interest accrued from the date hereof until the date of such interest payment. 
  
 1.2 If not sooner paid, the outstanding and unpaid principal balance shall be paid on October 1, 2000, together with
accrued and unpaid interest on this Note. In addition, interest shall be payable at the rate provided in Section 1.1 hereof on any Payment Premium from the date such premium is due until paid in full. 
  
 1.3 Principal, premium, if any, and interest on this note are payable in
lawful money of the United States. The principal of this Note may be prepaid at any time after ten (10) days, written notice to the Lender, in whole or in part, and shall be accompanied by payment in cash of all accrued and unpaid interest on
the amount so prepaid, together with, to the extent not prohibited by applicable law, a Payment Premium. 
  
 1.4 In the event of a Public Offering of the common stock of the Company, or in the event of a Refinancing, the principal then outstanding shall become
immediately due and payable, together with, accrued and unpaid interest thereon, and, to the extent not prohibited by applicable law, a Payment Premium in an amount equal to the lesser of (i) the Net Proceeds of such Public Offering or
Refinancing or (ii) the amount determined in accordance with §1.6 (iv) . The Net Proceeds shall be applied toward the payment of the outstanding and unpaid principal balance of the Notes, accrued and unpaid interest thereon and, to
the extent not prohibited by applicable law, such Payment Premium. 
  
 1.5 In the event of a Merger or Dissolution, the principal then outstanding shall become immediately due and payable, together with accrued and unpaid interest thereon and, to the extent not prohibited by applicable law, a Payment Premium
in the amount determined in accordance with § 1.6(iv). 
  
 1.6 Definitions. 
  

	 	(i)	 “Public Offering” shall mean the distribution and sale of the Company’s common stock (some of the proceeds of which sale are available to the
Company) pursuant to a registration statement 

  

 -2- 

	 	 
(other than a registration statement on Form S-4 or Form S-8) which has been filed with the U.S. Securities and Exchange Commission and become effective.

  

	 	(ii)	“Refinancing” shall mean a sale of securities of the Company which results in Net Proceeds to the Company in excess of $1,000,000, other than (a) obligations for
borrowed money due and payable within one year which are not extended, renewed or refinanced beyond such due date; (b) other obligations for money borrowed from NationsBank and/or its successors, substitutes and participants and their
respective assigns and any refinancing thereof. 

  

	 	(iii)	“Net Proceeds” shall mean the proceeds to the Company after expenses of sale and distribution, including discounts, commissions and brokerage and legal fees.

  

	 	(iv)	“Payment Premium” shall mean an amount equal to (a) 13 1/2% per annum, compounded semiannually from and after the date hereof until paid, on the principal amount
of this Note outstanding from time to time until the time of payment minus (b) the cumulative amount payable by the Company on account of withholding taxes with respect to interest payable pursuant to Section 1.1 to the date of payment of
such premium. For the avoidance of doubt, the Payment Premium shall not itself be increased on account of withholding taxes, but shall be subject to, and the amount remitted to the holder reduced by, any withholding tax to which the Payment Premium
is subject, with the result that the total cost to the Company for interest, Payment Premium and withholding taxes shall equal twenty-seven and one-half percent (27 1/2%) per annum on the principal outstanding from time to time to the date of

(as such terms are defined in Rule 13 (d) promulgated under the Securities Exchange Act of 1934, as amended), or a sale by the Company of all or substantially all of its assets. 

  

	 	(vi)	“Dissolution” shall mean the adoption by the Board of Directors and/or the shareholders of the Company of a resolution to dissolve the Company and liquidate its assets,

the adoption by the Board of Directors or the shareholders of the Company of a plan of liquidation or a resolution approving a liquidating distribution of the Company’s assets, whichever shall first occur. 

  
 1.7 At any time after the third anniversary of the date hereof, the holders
of a majority in outstanding principal amount of the Series B Notes and the Series C Notes issued by the Company contemporaneously herewith may request, in writing, that the Company effect a Public Offering, at the Company’s cost and expense.
Upon receipt of any such request, the Company shall, as expeditiously as possible, use its best efforts to effect a Public Offering, with the objective of realizing Net Proceeds sufficient to pay the then-outstanding principal balance of the Series
B Notes and the Series C Notes together with accrued, unpaid interest thereon, and, to the extent not prohibited by applicable law, a Payment Premium in an amount determined in accordance with § 1.4. 
  
 1.8 If any payment of principal or interest on this Note shall become due on
a Saturday, Sunday, or legal holiday under the laws of the Commonwealth of Virginia, or any other day on which banking institutions in the Commonwealth of Virginia are obligated or authorized by law or executive order to close, such payment shall be
made on the next succeeding business day in Virginia and any such extended time of the payment of principal shall not be included in computing compound interest in connection with such payment. 
  

 -4-

 I. GENERAL TERMS 

 
 1.1 Interest only shall be payable at the rate of fourteen percent
(14%) per annum, on the principal balance of this Note from time to time outstanding from and after the date hereof, and shall be due and payable quarterly, until the principal has been paid in full, on the first day of April, July, October,
and January in each year. Notwithstanding the foregoing, the rate of 

 
interest shall be increased to an amount necessary to result in a payment to the holder of fourteen percent (14%) per annum net of withholding for
United States Federal Income Taxes, it being contemplated that Borrower shall receive substantiation for Federal Income Tax purposes of circumstances supporting withholding at a rate no greater than seventeen and one-half percent (17 1/2%) of
interest hereunder. The first interest payment shall be due January 1, 1996 and shall include all interest accrued from the date hereof until the date of such interest payment. 
  
 1.2 If not sooner paid, the outstanding and unpaid principal balance shall be paid on October 1, 2000, together with
accrued and unpaid interest on this Note. In addition, interest shall be payable at the rate provided in Section 1.1 hereof on any. Payment Premium from the date such premium is due until paid in full. 
  
 1.3 Principal, premium, if any, and interest on this note are payable in
lawful money of the United States. The principal of this Note may be prepaid at any time after ten (10) days, written notice to the Lender, in whole or in part, and shall be accompanied by payment in cash of all accrued and unpaid interest on
the amount so prepaid, together with, to the extent not prohibited by applicable law, a Payment Premium. 
  
 1.4 In the event of a Public Offering of the common stock of the Company, or in the event of a Refinancing, the principal then outstanding shall become
immediately due and payable, together with, accrued and unpaid interest thereon, and, to the extent not prohibited by applicable law, a Payment Premium in an amount equal to the lesser of (i) the Net Proceeds of such Public Offering or
Refinancing or (ii) the amount determined in accordance with § 1.6(iv). The Net Proceeds shall be applied toward the payment of the outstanding and unpaid principal balance of the Notes, accrued and unpaid interest thereon and, to the
extent not prohibited by applicable law, such Payment Premium. 
  
 1.5 In the event of a Merger or Dissolution, the principal then outstanding shall become immediately due and payable, together with accrued and unpaid interest thereon and, to the extent not prohibited by applicable law, a Payment Premium
in the amount determined in accordance with § 1.6(iv). 
  
 1.6 Definitions.

such premium. For the avoidance of doubt, the Payment Premium shall not itself be increased on account of withholding taxes, but shall be subject to, and the amount remitted to the holder reduced by, any withholding tax to which the Payment Premium
is subject, with the result that the total cost to the Company for interest, Payment Premium and withholding taxes shall equal twenty-seven and one-half percent (27 1/2%) per annum on the principal outstanding from time to time to the date of

 1.8 If any payment of principal or interest on this Note shall become due on
a Saturday, Sunday, or legal holiday under the laws of the Commonwealth of Virginia, or any other day on which banking institutions in the Commonwealth of Virginia are obligated or authorized by law or executive order to close, such payment shall be

 8. Events of Default.

	 	(c)	The occurrence and continuance of any “Event of Default” as described in the Series B Notes or the Series C Notes. 

  
 Notwithstanding anything to the contrary contained herein, in the Series B
Notes or in the Series C Notes, the occurrence of an Event of Default under this Section 8 shall be deemed to constitute an Event of Default under the Series B Notes and the Series C Notes, which shall entitle the Lenders to take all actions
and to exercise all remedies available to the Lenders under the Series B Notes and Series C Notes, including the rights set forth in Sections 2.2 and 2.3 of such Notes. Further, notwithstanding anything to the contrary contained herein, in the

 9. Rights and Remedies Upon Default. 
  
 9.1. Subordination Agreement. Notwithstanding anything contained in
this Collateral Trust and Security Agreement to the contrary, all the rights and remedies of the Collateral Trustee and the rights and remedies of the Lenders and the Collateral Trustee with respect to the Collateral and the disposition thereof
shall be subject to the terms and conditions contained in the Subordination Agreement. If, and to the extent, any provision in this Collateral Trust and Security Agreement is inconsistent with the provisions of the 

  

 -15- 

 
Subordination Agreement, the provisions of the Subordination Agreement shall be binding. The Collateral Trustee hereby acknowledges that it has had presented
to it and has read the Subordination Agreement and agrees to be bound by all of the obligations of the Lenders therein as a party thereto, including the provisions of Sections 2.1, 2.2, 2.3, 2.4, 2.5 and 2.14. 
  
 9.2. Proceeds. Following the occurrence and during the continuance of
any Event of Default, or an event set forth in Section 8 hereof which, with the giving of notice or the lapse of time, or both, would constitute an Event of Default, any proceeds, if and when collected by the Grantor, whether consisting of
checks, notes, drafts, bills of exchange, money orders, commercial paper of any kind whatsoever, or other instruments or documents, received in payment for any Collateral shall be promptly turned over to the Collateral Trustee by the Grantor in
precisely the form received, except for its endorsement when required, and until so turned over, shall be deemed to be held in trust by the Grantor for and as the Collateral Trustee’s property and shall not be commingled with the Grantor’s
other funds. Such proceeds, when turned over, shall continue to be security for all of the Series B Notes and shall be applied by the Collateral Trustee on account of the Series B Notes in the order and manner set forth in Section 9.4 hereof.
Following the occurrence and during the continuance of any Event of Default, or an event set forth in Section 8 hereof which, with the giving of notice or the lapse of time, or both, would constitute an Event of Default, the Grantor shall
deliver to the Collateral Trustee all original and other documents evidencing, or relating to, the Collateral. 
  
 9.3. Payments. Upon the occurrence and during the continuance of any Event of Default: 
  
 (i) All payments received by the Grantor under or in
connection with any of the Collateral shall be held by the Grantor in trust for the Collateral Trustee, shall be segregated from other funds of the Grantor and shall forthwith upon receipt by the Grantor be turned over to the Collateral Trustee, in
the same form as received by the Grantor (duly endorsed by the Grantor to the Collateral Trustee, if required); and 
  
 (ii) any and all such payments so received by the Collateral Trustee (whether from the Grantor or otherwise) shall be applied by the
Collateral Trustee against the Series B Notes in such order and manner as set forth in Section 9.4 hereof. Any balance of such payments held by the Collateral Trustee and remaining after application in full of all such amounts to the Series B
Notes shall be held in trust for the account of and paid over to the Grantor or to whomsoever may be lawfully entitled to received the same. 
  
 9.4. Foreclosure. If any Event of Default shall occur and be continuing, the Collateral Trustee may exercise, in addition to all other rights and
remedies granted to it in this Collateral Trust and Security Agreement and in any other instrument, document or 

  

 -16- 

 
agreement securing, evidencing or relating to the Series B Notes, all rights and remedies of a secured party under the UCC or other applicable law. Without
limiting the generality of the foregoing, to the extent permitted by law, the Grantor expressly agrees that in any such event the Collateral Trustee, without demand of performance or other demand, advertisement or notice of any kind (except the
notice specified below of time and place of public or private sale) to or upon the Grantor or any other Person (all and each of which demands, advertisements and notices are hereby expressly waived), may forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and may forthwith sell, lease, assign, give an option or options to purchase, or otherwise dispose of and deliver said Collateral (or contract to do so), or any part thereof, at a public or private
sale or sales, at any exchange or broker’s board or at any of the Collateral Trustee’s offices or elsewhere at such price or prices as it may deem satisfactory, for cash or on credit or for future delivery without assumption of any credit
risk, and the Collateral Trustee may enter into any property where any Collateral is located and take possession thereof with or without judicial process; provided, however, that notwithstanding anything to the contrary contained in
this Collateral Trust and Security Agreement, the Collateral Trustee may not take any action to foreclose or otherwise realize upon the Collateral or to take possession of the Collateral except in express accordance with the Subordination Agreement
and Section 9.5 hereof. Prior to the disposition of any Collateral, the Collateral Trustee may store, process, repair or recondition the Collateral or otherwise prepare it for disposition in any manner and to the extent that the Collateral
Trustee deems appropriate. The Collateral Trustee shall have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of said Collateral so sold on
behalf of the Lenders, and to offset the purchase price thereof against the Series B Notes or any portion thereof, and thereafter to hold the same, absolutely free and clear of any claim or right of whatsoever kind, including any right or equity of
redemption in the Grantor, which right or equity is, to the extent permitted by law, hereby waived and released. Upon any such sale, the Collateral Trustee shall have the right to deliver, assign and transfer to the purchaser thereof the Collateral
sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right of whatsoever kind, including any right or equity of redemption in the Grantor, which right or equity is, to the extent permitted by law,
hereby waived and released, and any rights of stay or appraisal which the Grantor has or may have under any rule of law or statute now existing or hereafter adopted. Any such public or private sale shall be held at such time or times within ordinary
business hours and at such place or places as may be required by law, as the Collateral Trustee may fix in the notice of such sale. At any such private or public sale the Collateral may be sold as an entirety or in separate parcels, as the
Collateral Trustee may determine. The Collateral Trustee shall not be obligated to make any sale pursuant to any such notice. The Collateral Trustee may, without notice or publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for such sale, and such sale may without further notice be made at any time or place to which the same may be so adjourned. In case of any sale of all or any part of the
Collateral on credit or for future delivery, the Collateral so sold may be retained by the Collateral Trustee until the selling price is paid by the purchaser thereof, but the Collateral 

  

 -17- 

 
Trustee shall not incur any liability in case of the failure of such purchaser to take up and pay for the Collateral so sold and, in case of any such
failure, such Collateral may again be sold upon like notice. The Collateral Trustee, however, instead of exercising the power of sale herein conferred upon it may proceed by a suit or suits at law or in equity to foreclose the security interest
granted pursuant to this Collateral Trust and Security Agreement and sell the Collateral or any portion thereof, under a judgment or decree of court or courts of competent jurisdiction, the Grantor having been given notice of all such action. The
Grantor further agrees, at the Collateral Trustee’s request, to assemble the Collateral and make it available to the Collateral Trustee at places that the Collateral Trustee shall reasonably select, whether at the Grantor’s premises or
elsewhere. The proceeds of any such collection, sale, enforcement or other realization of all or any part of the Collateral, and any other cash at the time held by the Collateral Trustee pursuant to the terms of this Collateral Trust and Security
Agreement, shall be applied by the Collateral Trustee: 
  
 (i) First, to the payment of all costs and expenses of every kind paid or incurred by the Collateral Trustee in connection with this Collateral Trust and Security Agreement or the exercise of any right or remedy hereunder, including the
costs and expenses of any collection, sale, enforcement or other realization, and the costs and expenses incidental to the care or safe-keeping of any or all of the Collateral until such costs and expenses shall be paid in full; 
  
 (ii) Second, application to payment of the Series B Notes
(including any principal, interest, fees or expenses due under the terms of the Series B Notes) until all such Series B Notes shall be paid in full; and 
  
 (iii) Third, after the irrevocable payment in full of the amount referred to in paragraphs (i) and (ii), the balance, if any, shall
be paid over to such other Person or Persons as may be required by law. 
  
 To the
extent permitted by law, the Grantor waives all claims, damages and demands against the Collateral Trustee arising out of the repossession, retention or sale of the Collateral. The Grantor agrees that the Collateral Trustee need not give more than
ten business days’ prior notice (which notification shall be deemed given when mailed, postage prepaid, addressed to it at its address set forth in Section 11 hereof) of the time and place of any public sale or of the time after which a
private sale may take place and that such notice is reasonable notification of such matters. The Grantor shall remain liable for any deficiency if the proceeds of any sale or disposition of the Collateral are insufficient to pay all amounts to which
the Lenders are entitled, the Grantor also being liable for the fees of counsel employed by the Collateral Trustee to collect such deficiency. 
  
 9.5. Permission of Lenders. The Collateral Trustee may not foreclose, collect, receive, appropriate or realize upon the Collateral, or any part
thereof, or sell, lease, assign, give an option or options to purchase, or otherwise dispose of and deliver said Collateral (or 

  

 -18- 

 
contract to do so), or any part thereof, without the prior written consent of the Lenders holding at least 90% of the outstanding principal amount of the
Series B Notes at such time. In addition, any action, consent, waiver, instruction, or other approval by the Lenders under this Collateral Trust and Security Agreement shall require the prior written consent of the Lenders holding at least 90% of
the outstanding principal amount of the Series B Notes at such time. 
  
 9.6. Waivers of Notice. The Grantor waives presentment, demand, protest or any notice (to the extent permitted by law) of any kind in connection with this Collateral Trust and Security Agreement or any Collateral. 
  
 9.7. No Liability of the Collateral Trustee and the Lenders. Neither
the Collateral Trustee nor the Lenders shall incur any liability to the Grantor as a result of the sale of the Collateral, or any part thereof, at any private sale conducted in a commercially reasonable manner. The Grantor hereby waives any claims
against the Collateral Trustee and the Lenders arising by reason of the fact that the price at which the Collateral may have been sold at such private sale was less than the price which might have been obtained at a public sale or was less than the
aggregate amount of the Series B Notes even if the Collateral Trustee accepts the first offer received and does not offer the Collateral to more than one offeree; provided, that the Collateral Trustee conducts any such sale in a commercially
reasonable manner. 
  
 10. Limitation on Collateral Trustee’s Duty in
Respect of Collateral. Beyond the use of reasonable care in the custody and preservation thereof, the Collateral Trustee shall not have any duty as to any Collateral in its possession or control or in the possession or control of any agent or
nominee of the Collateral Trustee or any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto. 
  
 11. Notices. Any notice or any other communication to a Lender shall be given in writing and deemed received when delivered by overnight courier or hand delivery,

shall be valid as to the Collateral Trustee unless in writing and signed by the Collateral Trustee and then only to the extent therein set forth. A waiver by the Collateral Trustee of any right or remedy hereunder on any one occasion shall not be

hereunder, shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and
remedies hereunder provided are cumulative and may be exercised singly or concurrently, and are not exclusive of any rights and remedies provided by law. None of the terms or provisions of this Collateral Trust

such Lender. 
  
 14. Governing Law. This Collateral Trust and Security
Agreement, and all rights, obligations and liabilities arising hereunder, shall be governed by and construed in
accordance with the internal laws of the Commonwealth of Virginia. 
  
 15.
Severability. Any provision of this Collateral Trust and Security Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 
  
 16. Security Interest Absolute. All rights of the Collateral Trustee and security
interests hereunder, and all obligations of the Grantor hereunder, shall be absolute and unconditional irrespective
of: 
  

	 	(a)	any lack of validity or enforceability of any provision of any Series B Note; 

  

	 	(b)	any change in the time, manner or place of payment of, or in any other term of, all or any of the Series B Notes; 

  

	 	(c)	any exchange, release or non-perfection of any Collateral, or any release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Series B Notes;
or 

  

	 	(d)	any other circumstance which might otherwise constitute a defense available to, or a discharge of the Grantor. 

  
 17. Further Indemnification. The Grantor agrees to pay, and to hold harmless the
Collateral Trustee and the Lenders from, any and all liabilities with respect to, or resulting from any delay in paying, any and all excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral
or in connection with any of the transactions contemplated by this Collateral Trust and Security Agreement. 
  

 -21- 

 18. Termination. When all the Series B Notes shall have been fully, finally and indefeasibly paid, discharged and
retired, this Collateral Trust and Security Agreement shall terminate, and the Collateral Trustee shall forthwith cause to be assigned, transferred and delivered, against receipt but without any recourse, warranty or representation whatsoever, the
Collateral and any money received in respect thereof, to or on the order of the Grantor, and to execute such termination statements as required by the Grantor. 
  

19. Counterparts. This Collateral Trust and Security Agreement may be executed in one or more counterparts and all of such counterparts taken together shall
constitute one and the same instrument.

 WHEREAS, Borrowers, Credit Parties, Agent and certain
other financial institutions from time to time party thereto (the “Lenders”) are parties to that certain Loan and Security Agreement dated as of October 21, 2002 (as amended from time to time, the “Loan Agreement”);

  
 WHEREAS, Companies have informed Agent that (a) in
December 2003 Parent paid $500,000 in cash to Enterworks, Inc., a Delaware corporation (“Enterworks”) as a prepayment of development, testing and technical support to be provided by Enterworks International, Inc., a Delaware corporation
(“EI”) (which at the time of such $500,000 payment was a wholly-owned subsidiary of Enterworks) to Parent during the fiscal year ending December 31, 2004 and in consideration for such payment to Enterworks, Parent received and became
the owner of fifty percent (50%) of the equity interests of EI, and (b) in December 2003 Parent purchased from Enterworks software having a value of approximately $1,000,000 and in consideration therefor Parent paid $100,000 in cash to

 2. Waiver. Subject to the satisfaction of the conditions set forth in Section 6 hereof, Agent and Lenders hereby waive the Existing Defaults.
The foregoing waiver shall not constitute a waiver of any other Event of Default that may exist, or a waiver of any future Event of Default that may occur (including, without limitation, any breach of Section 6.3(b) of the Loan Agreement for
any fiscal year ending after December 31, 2003 and any breach of Section 7.20(a)(ii) of the Loan Agreement for any applicable date after December 31, 2003).

provision of law applicable to it, its articles of incorporation and by-laws, any order, judgment or decree of any court or governmental agency, or any agreement, instrument or document binding upon it or any of its property; 
  
 (ii) Each of the Loan Agreement and the other Loan

 Waiver and Seventh Amendment
to Loan and Security Agreement between 
  
 Telos Corporation, a

 (formerly
known as Foothill Capital Corporation) entered into 
  
 as of
August 20, 2004 

  
 WAIVER AND SEVENTH
AMENDMENT TO 
 LOAN AND SECURITY AGREEMENT 
  

THIS WAIVER AND SEVENTH AMENDMENT TO LOAN AND SECURITY AGREEMENT (this “Amendment”) is entered into as of August 20, 2004, by and among
TELOS CORPORATION, a Maryland corporation (“Parent”), XACTA CORPORATION, a Delaware corporation (“Xacta”; Parent and Xacta are referred to hereinafter each individually as a “Borrower”, and individually
and collectively, jointly and severally, as the “Borrowers”), TELOS DELAWARE, INC., a Delaware corporation (“Telos-Delaware”), UBIQUITY.COM, INC., a Delaware corporation (“Ubiquity”), TELOS.COM, INC.,
a Delaware corporation (“Telos.com”), TELOS INTERNATIONAL CORP., a Delaware corporation (“TIC”), TELOS INTERNATIONAL ASIA, INC., a Delaware corporation (“TIA”), SECURE TRADE, INC., a Delaware
corporation (“STI”), KUWAIT INTERNATIONAL, INC., a Delaware corporation (“KII”), TELOS INFORMATION SYSTEMS, INC., a Delaware corporation (“TIS”), TELOS FIELD ENGINEERING, INC., a Delaware
corporation (“TFE”), and TELOS FEDERAL SYSTEMS, INC., a Delaware corporation (“TFS”; Telos-Delaware, Ubiquity, Telos.com, TIC, TIA, STI, KII, TIS, TFE and TFS are referred to hereinafter each individually as a “Credit
Party” and collectively, jointly and severally, as the “Credit Parties”), and WELLS FARGO FOOTHILL, INC. (formerly known as Foothill Capital Corporation), as agent (“Agent”) for the Lenders (defined below) and as a
Lender. 
  
 WHEREAS, Borrowers, Credit Parties, Agent and certain
other financial institutions from time to time party thereto (the “Lenders”) are parties to that certain Loan and Security Agreement dated as of October 21, 2002 (as amended from time to time, the “Loan Agreement”);

  
 WHEREAS, (a) Companies were unable to deliver to Agent
duly authorized evidence that the holders of Permitted Indebtedness have extended the maturity date thereof to October 31, 2005 (it being acknowledged that according to the Companies, the Companies have obtained confirmation from such holders
that such holders have extended such maturity date), which resulted in a breach of Section 17 of the Subordination Agreement and therefore an Event of Default under Section 8.2 of the Loan Agreement (the “Subordination Event of
Default”), and (b) as of each of May 31, 2004 and June 30, 2004, Companies failed to maintain Tangible Net Worth of 80% (or if negative, 120%) of the Tangible Net Worth as of such date as reflected on the most recent Projections,
which resulted in a breach of Section 7.20(a)(ii) of the Loan Agreement and therefore an Event of Default under Section 8.2 of the Loan Agreement (the “Tangible Net Worth Events of Default”; the Tangible Net Worth Events of
Default together with the Subordination Event of Default are collectively, the “Existing Defaults”), and Borrowers have requested that Agent and Lenders waive the Existing Defaults and Agent and Lenders have agreed to do so subject to the
terms and conditions contained herein; and 
  
 WHEREAS, Borrowers,
Credit Parties, Agent and Lenders have agreed to amend the Loan Agreement in certain respects, subject to the terms and conditions contained herein. 

 NOW THEREFORE, in consideration of the premises and mutual agreements herein contained, the parties
hereto agree as follows: 
  
 1. Defined Terms. Unless
otherwise defined herein, capitalized terms used herein shall have the meanings ascribed to such terms in the Loan Agreement. 
  
 2. Waiver. Subject to the satisfaction of the conditions set forth in Section 5 hereof, Agent and Lenders hereby waive the Existing Defaults.
The foregoing waivers shall not constitute a waiver of any other Event of Default that may exist, or a waiver of any future Event of Default that may occur. 
  
 3. Amendments to Loan Agreement. Subject to the satisfaction of the conditions set forth in Section 5 hereof, the Loan Agreement is hereby
amended by deleting Section 7.20(a)(ii) in its entirety (thereby eliminating the Tangible Net Worth covenant) and restating Section 7.20(a)(ii) in its entirety as follows: 
  

	 	(ii)	Reserved. 

  
 4. Ratification. This Amendment, subject to satisfaction of the conditions provided below, shall constitute a waiver and amendment to the Loan
Agreement and all of the Loan Documents as appropriate to express the agreements contained herein. Except as specifically set forth herein, the Loan Agreement and the Loan Documents shall remain unchanged and in full force and effect in accordance
with their original terms. 
  
 5. Conditions to
Effectiveness. The satisfaction of each of the following, unless waived or deferred by Agent and Lenders in their sole discretion, shall constitute conditions precedent to the effectiveness of this Amendment: 
  
 (a) Agent shall have received this Amendment, duly executed by Credit
Parties; 
  
 (b) Agent shall have received the waiver and
amendment fee described in Section 6 hereof; and 
  
 (c) No
Event of Default or event which with the giving of notice or passage of time would constitute an Event of Default, other than the Existing Defaults, shall have occurred and be continuing on the date hereof, nor shall result from the consummation of
the transaction contemplated herein. 
  
 6. Waiver and
Amendment Fee. To induce Agent and Lenders to enter into this Amendment, Borrowers shall pay to Agent, for the benefit of Lenders, a non- refundable waiver and amendment fee equal to $2,500, which shall be due and payable on the date hereof.

  
 7. Other Agreements. Notwithstanding anything to the
contrary in Section 8.16 of the Loan Agreement and Section 17 of the Subordination Agreement, Companies agree to deliver to Agent no later than September 1, 2004 written evidence, in form and 

  

 -2- 

 
content satisfactory to Agent, that the holders of the Permitted Indebtedness have amended the maturity date thereof to a date no earlier than
October 15, 2005. Any breach by Companies of this Section 7 shall constitute an Event of Default under the Loan Agreement. 
  
 8. Miscellaneous. 
  
 (a) Warranties and Absence of Defaults. To induce Agent and Lenders to enter into this Amendment, each Company hereby represents and warrants to
Agent and Lenders that: 
  
 (i) The execution,
delivery and performance by it of this Amendment and each of the other agreements, instruments and documents contemplated hereby are within its corporate power, have been duly authorized by all necessary corporate action, have received all necessary
governmental approval (if any shall be required), and do not and will not contravene or conflict with any provision of law applicable to it, its articles of incorporation and by-laws, any order, judgment or decree of any court or governmental
agency, or any agreement, instrument or document binding upon it or any of its property; 
  
 (ii) Each of the Loan Agreement and the other Loan Documents, as amended by this Amendment, are the legal, valid and binding obligation of

observed and performed by it and no event of default or other event which upon notice or lapse of time or both would constitute an event of default has occurred. 
  
 (b) Expenses. Companies, jointly and severally, agree to pay on demand all costs and expenses of Agent (including the
reasonable fees and expenses of outside counsel for Agent) in connection with the preparation, negotiation, execution, delivery and administration of this Amendment and all other instruments or documents provided for herein or delivered or to be
delivered hereunder or in connection herewith. In addition, Companies agree, jointly and severally, to pay, and save Agent harmless from all liability for, any stamp or other taxes which may be payable in connection with the execution or delivery of
this Amendment or the Loan Agreement, as amended hereby, and the execution and delivery of any instruments or documents provided for herein or delivered or to be delivered hereunder or in connection 

  

 -3- 

 
herewith. All obligations provided herein shall survive any termination of the Loan Agreement as amended hereby. 
  
 (c) Governing Law. This Amendment shall be a contract made under and
governed by the internal laws of the State of Illinois. 
  
 (d)
Counterparts. This Amendment may be executed in any number of counterparts, and by the parties hereto on the same or separate counterparts, and each such counterpart, when executed and delivered, shall be deemed to be an original, but all
such counterparts shall together constitute but one and the same Amendment. 
  
 9. Release.

consideration of the agreements of Agent and Lenders contained herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, each Company, on behalf of itself and its successors, assigns, and
