a party hereto (the “Subsidiary Guarantors”), and BANK OF AMERICA, N.A., a national banking association (the “Lender”). 
  
 W I T N E S S E T H 
  
 WHEREAS, the Borrower has requested that the Lender extend
credit to it in order to enable it to borrow on a committed revolving credit basis from and after the date hereof and at any time and from time to time prior to the Revolving Credit Facility Maturity Date (as hereinafter defined) in an aggregate
principal amount not to exceed Four Million and 00/100 Dollars ($4,000,000.00) at any time outstanding; and 
  
 WHEREAS, the Borrower has requested that the Lender extend credit to it in order to enable it to borrow on a term loan basis in an aggregate amount not to exceed Three Million Five Hundred Thousand and 00/100 Dollars
($3,500,000.00); and 
  
 WHEREAS, the Lender is willing to extend such credit to the Borrower on the terms and subject
to the conditions hereinafter set forth. 
  
 NOW, THEREFORE, in consideration of the premises and of the mutual covenants
herein contained, and intending to be legally bound hereby, the parties hereto hereby covenant and agree as follows:

 “Affiliate” of a Person (the “Specified Person”) shall mean (a) any Person which directly or indirectly controls, or is
controlled by, or is under common control with, the Specified Person, (b) any director or officer (or, in the case of a Person which is not a corporation, any individual having analogous powers) of the Specified Person or of a Person who is
an Affiliate of the Specified Person within the meaning of the preceding clause (a), and (c) for each individual who is an Affiliate of the Specified Person within the meaning of the foregoing clause (a) or (b), any spouse or direct lineal
descendant of such Affiliate. For purposes of the preceding sentence, “control” of a Person shall mean (x) the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of
such Person, whether through the ownership of voting securities, by contract or otherwise, and (y) in any case shall include direct or indirect ownership (beneficially or of record) of, or direct or indirect power to vote, ten

Borrower may terminate the Lender’s obligation to make Revolving Credit Facility Loans; provided that the Borrower shall have provided written notice thereof to the Lender at least five (5) Business Days prior to the termination date. On the
termination date, the principal amounts of all Revolving Credit Facility Loans, together with interest on each such principal amount and any fees or expenses owed to the Lender to such date, shall be due and payable and all Letter of Credit
Obligations shall be satisfied. The Borrower may from time to time prior to the Revolving Credit Facility Maturity Date reduce the Revolving Credit Facility Committed Amount of the Lender to an aggregate amount not less than the sum of the unpaid
principal amount of the Revolving Credit Facility Loans then outstanding plus the principal amount of all Revolving Credit Facility Loans not yet made as to which notice has been given by the Borrower plus all Letter of Credit
Obligations; provided that there shall be no Default. Reduction of the Revolving Credit Facility Committed Amount shall be made by providing not less than five (5) Business Days’ notice (which notice shall be irrevocable) to such effect to the
Lender. 
  
  
 2.2.  
Term Loan. 
  
 (a)  Term Loan
Commitment.    Subject to the terms and conditions and relying upon the representations and warranties of the Borrower herein set forth, the Lender agrees (such agreement being herein called the Lender’s “Term

 (b)  Nature of Credit.    The Borrower may not borrow any new amounts or reborrow amounts
repaid with respect to the Term Loan. 
  
 (c)  Term Loan Note.    The
obligation of the Borrower to repay the unpaid principal amount of the Term Loan and to pay interest thereon shall be evidenced in part by a promissory note of the Borrower dated the Closing Date (the “Term Loan Note”), in
substantially the form attached hereto 
 

 20 

  
 as Exhibit B, with the blanks appropriately filled, payable to the order of the Lender
in a face amount equal to Three Million Five Hundred Thousand and 00/100 Dollars ($3,500,000.00).

 2.3.  
Fees. 
  
 (a)  Revolving Unused
Fee.    The Borrower shall pay to the Lender for each day during the period set forth below a commitment fee (the “Revolving Unused Fee”) at a rate per annum equal to the Applicable Margin, multiplied
by the following amount: for each day from and including the date hereof to but not including the Revolving Credit Facility Maturity Date, the amount (not less than zero) equal to (i) the Revolving Credit Facility Committed Amount on such
day, minus (ii) the aggregate principal amount of all Revolving Credit Facility Loans, plus the aggregate Letter of Credit Obligations on such day. The Revolving Unused Fee shall be due and payable for the preceding period for which
such fee has not been paid: (x) on the first Regular Interest Payment Date of each calendar quarter, and (y) on the Revolving Credit Facility Maturity Date. 
  
 (b)  Administration Fee.    An administration fee in the amount of Fifteen Thousand Dollars and 00/100 ($15,000.00)
shall be paid each year, payable in advance in equal quarterly payments, beginning on the Closing Date and on the first day of each calendar quarter thereafter until the Obligations are paid in full and the Revolving Credit Facility Commitment is
terminated. 
  
 (c)  Origination Fee.    An origination fee in the
amount of Seventy-Five Thousand and 00/100 Dollars ($75,000.00) shall be paid on the Closing Date. 
  
 2.4.  
Making of Loans. 
  
 (a)  Loan
Requests.    Whenever the Borrower desires that the Lender make Revolving Credit Facility Loans, the Borrower shall provide notice to the Lender setting forth the following information: 
  
 (i)  The date, which shall be a Business Day, on which such proposed Loans are to be made; and 
 

 21 

 (ii)  The aggregate principal amount of such proposed Loans, which shall be in integral multiples of
$50,000. 
  
 Unless any applicable condition specified in Article 4 has not been satisfied, on the date specified in such notice
the Lender shall make the proceeds of the Loan available to the Borrower requesting such Loan in funds immediately available. 
  
 (b)  Automatic Loans.    In addition to the foregoing, the Borrower authorizes the Lender to make Revolving Credit Facility Loans, if all applicable conditions specified in
Article 4 have been satisfied, in accordance with the terms of the Automatic Service Agreement between the Borrower and the Lender (the “Autoborrow Service Agreement”). 
  
 (c)  Swap Contracts and ACH Transactions.    If the Borrower fails to make a payment to the Lender under a Swap Contract or
pursuant to an obligation arising from an ACH Transaction, the Lender may, but is not required to, advance such payment for the account of the Borrower and such advance shall be deemed to be a Revolving Credit Facility Loan. For purposes of this
Section 2.4(c), “ACH Transactions” shall mean any transaction involving cash management or related services, including the transfer of funds through an automated clearinghouse by the Lender for the account of the Borrower. 

 
 2.5.  
Interest Rates. 
  
 (a)  LIBOR
Rate.    The unpaid principal amount of the Loans shall bear interest for each day until due at the LIBOR Rate plus the Applicable Margin. 
  
 (b)  360-Day Year.    All interest payable hereunder shall be calculated on the basis of a 360-day year, counting the actual
number of days elapsed. 
  
 2.6.  
Intentionally Deleted. 
  
 2.7.  
Optional Prepayments of Term Loan. 
  
 Whenever the Borrower desires to prepay any part of the Term
Loan, it shall provide a separate notice setting forth the following information with respect to each sum being prepaid: 
  
 (a)  The date, which shall be a Business Day, on which the proposed prepayment is to be made; and 
  
 (b)  The principal amount to be prepaid. 
  
 Notice having been so provided, on the date specified in such notice, the principal amounts of the Term Loan specified in such notice, together with interest on each such principal amount to such date, shall be due
and payable. Any 
 

 22 

  
 prepayments made with respect to the Term Loan shall be applied in inverse order of maturity. In addition, within five
(5) days after demand by the Lender, the Borrower shall pay to the Lender the amount of any Consequential Loss. “Consequential Loss” shall mean such amount as will compensate the Lender for any loss, cost, expense, penalty, claim or
liability incurred by it as a result of the prepayment or the failure to make a prepayment, including any loss of anticipated profits and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain the credit
or from fees payable to terminate the deposits from which such funds were obtained. The Borrower shall also pay any customary administrative fees charged by the Lender in connection with the foregoing. For purposes of this paragraph, the Lender
shall be deemed to have funded the credit by a matching deposit or other borrowing in the applicable interbank market, whether or not the credit was in fact so funded. The Lender shall deliver to the Borrower a certificate as to the amount of the
Consequential Loss, which certificate shall be conclusive in the absence of manifest error. 
  
 2.8.  
Optional Prepayments of Revolving Credit Facility Loans. 
  
 The Borrower shall have the right at its
option from time to time to prepay the Revolving Credit Facility Loans in whole or part at any time without premium or penalty. 
  
 2.9.  
Mandatory Prepayments. 
  
 (a)  Borrowing
Base.    If at any time the aggregate outstanding principal amount of Revolving Credit Facility Loans, plus Letter of Credit Obligations, plus the outstanding principal amount of the Term Loan exceeds the
Borrowing Base, the Borrower shall prepay a principal amount of the Loans, in an aggregate amount not less than the amount of such excess, concurrently with the delivery of any Borrowing Base/Non-Default Certificate which shows such an excess.
Prepayments required by this Section 2.9 shall be applied as follows: to pay all accrued but unpaid interest on, and then the principal of, the Revolving Credit Facility Loans and then, to pay all accrued but unpaid interest on, and then the
principal of, the Term Loan. 
  
 (b)  Excess Cash Flow.    Within 120
days after the end of each fiscal year of the Borrower (beginning with the fiscal year ending December 31, 2002), the Borrower shall prepay the Term Loan in an aggregate amount equal to 50% of the Excess Cash Flow for such prior fiscal year.

  
 2.10.  
Interest Payment Dates. 
  
 Interest on the Loans shall be due and payable on each Regular Interest
Payment Date. After maturity of any part of the Loans (by acceleration or otherwise), interest on such part shall be due and payable on demand. 
  
 2.11.  
Payments Generally. 
 

 23 

  
 (a)  Payments Generally.    All
payments and prepayments to be made by the Borrower in respect of principal, interest, fees, indemnity, expenses or other amounts due from the Borrower hereunder or under any other Loan Document shall be payable in Dollars by 1:00 o’clock p.m.,
Charlotte time, on the day when due without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived, and, upon any failure to make any such payment when so due and expiration of any applicable cure period with
respect to such payment, an action therefor shall immediately accrue, without setoff, counterclaim, withholding or other deduction of any kind or nature. Such payments shall be made to the Lender in Dollars in funds immediately available. Any
payment or prepayment received by the Lender after 1:00 o’clock p.m., Charlotte time, on any day shall be deemed to have been received on the next succeeding Business Day. 
  
 (b)  Interest on Overdue Amounts.    To the extent permitted by law, after there shall have become due (by acceleration or
otherwise) principal, interest, fees, indemnity, expenses or any other amounts due from the Borrower hereunder or under any other Loan Document, such amounts shall bear interest for each day until paid (before and after judgment), payable on demand,
at a rate per annum which for each day shall be equal to a rate per annum two percent (2%) above the rate otherwise applicable (or if no rate is applicable, whether in respect of interest, fees or other amounts, then four percent (4.0%) greater than
the Prime Rate). 
  
 To the extent permitted by law, interest accrued on any amount which has become due hereunder or under any
other Loan Document shall compound on a day-by-day basis, and hence shall be added daily to the overdue amount to which such interest relates. 
  
 (c)  Automatic Debit.    The Borrower has elected to authorize the Lender to effect payment of sums due under this Agreement
and the other Loan Documents by means of debiting the Borrower’s account number 4124657128. This authorization shall not affect the obligation of the Borrower to pay such sums when due, without notice, if there are insufficient funds in such
account to make such payment in full on the due date thereof, or if the Lender fails to debit the account. Without limiting the foregoing, the Borrower has authorized the Lender to effect payment of sums due under this Agreement in connection with
the Revolving Credit Facility Loans in accordance with the Autoborrow Service Agreement. 
  
 2.12.  
Additional Compensation in Certain Circumstances. 
  
 Increased Costs or Reduced Return Resulting
From Taxes, Reserves, Capital Adequacy Requirements, Expenses, Etc.    If any Law or guideline or interpretation 
 

 24 

  
 or application thereof by any Governmental Authority charged with the interpretation or administration thereof or
compliance with any request or directive of any Governmental Authority (whether or not having the force of law) now existing or hereafter adopted: 
  
 (i)  subjects the Lender to any tax or changes the basis of taxation with respect to this Agreement, the Notes, the Commitments, the Loans, or payments
by the Borrower of principal, interest, fees or other amounts due from the Borrower hereunder or under the Notes (except for taxes payable by the Lender based on the overall net income or gross receipts of the Lender imposed by the jurisdictions
foreign, federal, state and/or local) in which the Lender’s principal office is located), 
  
 (ii)  imposes, modifies or deems applicable any reserve, special deposit or similar requirement against credits or commitments to extend credit extended by, assets (funded or contingent) of, deposits with or for the account
of, other acquisitions of funds by, the Lender (other than requirements expressly included herein in the determination of the LIBOR Rate hereunder), 
  
 (iii)  imposes, modifies or deems applicable any capital adequacy or similar requirement (A) against assets (funded or contingent) of, or
credits or commitments to extend credit extended by, the Lender, or (B) otherwise applicable to the obligations of the Lender under this Agreement, or 
  
 (iv)  imposes upon the Lender any other condition or expense with respect to this Agreement, the Notes, the Commitments or its making, maintenance or
funding of any Loan, Letter of Credit, or any security for any thereof, 
  
 and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by, or impose any expense (including loss of margin) upon the Lender, or, in the case of clause (iii), any Person controlling the Lender, with respect to this Agreement, the Notes, the Commitments or the making, maintenance or
funding of any Loan or Letter of Credit, (or, in the case of any capital adequacy or similar requirement, to have the effect of reducing the rate of return on the Lender’s or controlling Person’s capital, taking into consideration the
Lender’s or controlling Person’s policies with respect to capital adequacy) by an amount which the Lender deems to be material, the Lender may from time to time notify the Borrower of the amount determined (using any averaging and
attribution methods) by the Lender (which determination shall be conclusive) to be necessary to compensate the Lender for such increase, reduction or imposition. In making any such determination the Lender may take into account any special,
supplemental or other nonrecurring items, may apply any averaging or attribution methods, and may make such determination prospectively or retrospectively. 
 

 25 

  
 Such amount shall be due and payable by the Borrower to the Lender five Business Days after such notice is given.

  
 2.13.  
Taxes. 
  
 (a)  Payments Net of
Taxes.    All payments made by the Borrower under this Agreement or any other Loan Document shall be made free and clear of, and without reduction or withholding for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, and all liabilities with respect thereto, excluding 

 
 (i)  income, gross receipts or franchise taxes imposed on the Lender by the jurisdiction under the laws of
which the Lender is organized or any political subdivision or taxing authority thereof or therein or as a result of a connection between Lender and any jurisdiction other than a connection resulting solely from this Agreement and the transactions
contemplated hereby, and 
  
 (ii)  income, gross receipts or franchise taxes imposed by any
jurisdiction in which the Lender’s lending offices which make or book Loans are located or any political subdivision or taxing authority thereof or therein (all such non-excluded taxes, levies, imposts, deductions, charges or withholdings being
hereinafter called “Taxes”). If any Taxes are required to be withheld or deducted from any amounts payable to the Lender under this Agreement or any other Loan Document, the Borrower shall pay the relevant amount of such Taxes and
the amounts so payable to the Lender shall be increased to the extent necessary to yield to the Lender (after payment of all Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement and
the other Loan Documents. Whenever any Taxes are paid by the Borrower with respect to payments made in connection with this Agreement or any other Loan Document, as promptly as possible thereafter, the Borrower shall send to the Lender, as the case
may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. 
  
 (b)  Indemnity.    The Borrower hereby indemnifies the Lender for the full amount of all Taxes attributable to payments by or on behalf of the Borrower hereunder or under any of the other Loan
Documents, any Taxes paid by the Lender, any present or future claims, liabilities or losses, including, without limitation, reasonable and documented attorneys’ fees, with respect to or resulting from any omission to pay or delay in paying any
Taxes (including any incremental Taxes, interest or penalties that may 
 

 26 

  
 become payable by the Lender as a result of any failure to pay such Taxes), whether or not such
Taxes were correctly or legally asserted. Such indemnification shall be made within five (5) days from the date the Lender makes written demand therefor. 
  
 (c)  The agreements in this Section 2.13 shall survive the termination of this Agreement and the other Loan Documents, and all other amounts payable
hereunder. 
  
 2.14.  
Intentionally Deleted. 
  
 2.15.  
Borrowing Base. 
  
 (a)  Borrowing

 (i)  Ninety percent (90%) of the Net Value (as hereinafter defined) of Eligible Billed
Receivables representing amounts due and owing from the Government (or from a prime contractor under a contract with the Government with respect to which the Borrower is a subcontractor), which are outstanding less than ninety-one (91) days from the
date of original invoice; plus 
  
 (ii)  Eighty percent (80%) of the Net Value of
Eligible Billed Receivables representing amounts due and owing from domestic account debtors (other than the Government), which are outstanding less than ninety-one (91) days from the date of original invoice; plus 
  
 (iii)  The lesser of (A) fifty percent (50%) of the Net Value of Eligible Unbilled Receivables and (B) $1,000,000;
plus 
  
 (iv)  $2,000,000. 
  
 The “Net Value” of an Eligible Billed Receivable or an Eligible Unbilled Receivable shall be its face amount, net of any discount for prompt payment
(and net of any other amount representing payment of finance charges, late charges, or interest (however denominated)), and net of any portion thereof which constitutes payment of sales, use or other taxes. 
  
 (b)  Borrowing Base/Non-Default Certificates.    On the Closing Date and monthly
thereafter the Borrower shall furnish to the Lender a certificate (each, a “Borrowing Base/Non-Default Certificate”) substantially in the form of Exhibit D hereto, appropriately completed and signed by a Responsible Officer
of the Borrower and setting forth the information required therein. Borrowing Base/Non-Default Certificates shall be 
 

 27 

  
 delivered to the Lender within twenty (20) days following the last day of each calendar month
or at such other time as the Lender may specify in its sole and absolute discretion. 
  
 To the extent that the
Borrower is required to deliver a Borrowing Base/Non-Default Certificate on a particular day, the Eligible Billed Receivables and the Eligible Unbilled Receivables reflected on such Borrowing Base/Non-Default Certificate, the Net Values applicable
thereto, and the calculations of the Borrowing Base thereunder, shall be determined as of the last day of the month immediately preceding the date of such Borrowing Base/Non-Default Certificate or as of such other date as the Lender may specify. The
Borrowing Base determined pursuant to any such Borrowing Base/Non-Default Certificate shall be effective until delivery of a subsequent Borrowing Base/Non-Default Certificate. 
  
 2.16.  
Letters of Credit. 
  
 (a)  General.    Subject to the terms and conditions of this Agreement, and relying upon the representations and warranties herein set forth, the Lender shall issue for the account of the Borrower
Letters of Credit at any time or from time to time on or after the date hereof. The Borrower shall not request any Letter of Credit to be issued (and the Lender shall not be obligated to issue any Letter of Credit) except within the following
limitations: on the date of issuance of any Letter of Credit (and after giving effect to such issuance): the sum of the aggregate Letter of Credit Obligations plus the aggregate amount of all Revolving Credit Facility Loans outstanding shall not
exceed the Revolving Credit Facility Available Amount.

and conditions of this Agreement, each Letter of Credit shall be subject to any other reasonable requirements for letters of credit normally and customarily imposed by the Lender. 
  
 (c)  Letter of Credit Fees.    The Borrower shall pay a fee (the “Letter of Credit Fee”), with respect to each
Letter of Credit, in the amount of the Applicable Margin applied to the face amount of such Letter of Credit, payable before such Letter of Credit is issued. The Borrower shall also pay to the Lender such Letter of Credit administrative, amendment
and other fees based on the Lender’s standard pricing for such fees, as amended from time to time. 
 

 28 

  
 2.17.  
Procedure for Issuance and Amendment of Letters of Credit. 
  
 (a)  Request for Issuance.    The Borrower may from time to time request, upon at least three (3) Business Days’ notice, the Lender to issue a Letter of Credit by: 
  
 (i)  delivering to the Lender a written request to such effect, specifying the date on which such Letter of Credit is
to be issued, the expiration date thereof, and the stated amount thereof, and 
  
 (ii)  delivering to the Lender an application, in such form as may from time to time be approved by the Lender (the “Letter of Credit Application”), completed to the satisfaction of the Lender, together
with such other certificates, documents and other papers and information as the Lender may request. 
  
 If all conditions precedent
to the issuance of a Letter of Credit are fulfilled, the Lender shall deliver the original of such Letter of Credit to the beneficiary thereof or as the Borrower shall otherwise direct. 
  
 (b)  Request for Extension or Increase.    The Borrower may from time to time request the Lender to extend the expiration date of an
outstanding Letter of Credit or increase the Letter of Credit Undrawn Availability of such Letter of Credit. Such extension or increase shall for all purposes hereunder be treated as though the Borrower had requested issuance of a replacement Letter
of Credit (except only that the Lender may, if it elects, issue a notice of extension or increase in lieu of issuing a new Letter of Credit in substitution for the outstanding Letter of Credit). 
  

2.18.  
Letter of Credit Drawings and Reimbursements. 
  
 The Borrower hereby agrees to reimburse the Lender,
by making payment to the Lender in accordance with Section 2.11(a), on the date and in the amount of each payment made by the Lender under any Letter of Credit, upon notice (which may be by telephone) by the Lender to the Borrower of such payment,
without further notice, protest or demand, all of which are hereby waived, and an action therefor shall thereupon immediately accrue. To the extent such payment is not timely made, the Borrower hereby agrees to pay to the Lender on demand, interest
on any Letter of Credit Unreimbursed Draws for each day from and including the date of such payment by the Lender until reimbursed in full (before and after judgment), in accordance with Section 2.11(b), at the rate per annum set forth in Section
2.11(b). 
  
 2.19.  
Obligations Absolute. 
  
 The payment obligations of the Borrower under Section 2.18 shall be
unconditional and irrevocable and shall be paid strictly in accordance with the 
 

 29 

  
 terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

  
 (a)  any lack of validity or enforceability of this Agreement, any Letter of Credit or any
other Loan Document; 
  
 (b)  the existence of any claim, set-off, defense or other right which
Borrower or any other Person may have at any time against any beneficiary or transferee of any Letter of Credit (or any Persons for whom any such beneficiary or transferee may be acting), the Lender, or any other Person, whether in connection with
this Agreement, the transactions contemplated hereby or any unrelated transaction; 
  
 (c)  any
draft, certificate, statement or other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect, unless payment by the
Lender under such circumstances results solely from the gross negligence or willful misconduct of the Lender; 
  
 (d)  payment by the Lender under any Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit, or payment by the Lender under the Letter of Credit in any
other circumstances in which conditions to payment are not met, except any such payment resulting solely from the gross negligence or willful misconduct of the Lender; or 
  
 (e)  any other event, condition or circumstance whatever, whether or not similar to any of the foregoing. 
  
 The Borrower bears the risk of, and neither the Lender nor any of its directors, officers, employees or Lenders shall be liable or responsible for any
of, the foregoing matters, the use which may be made of any Letter of Credit, or acts or omissions of the beneficiary or any transferee in connection therewith. 
  
 2.20.  
Further Assurances. 
  
 The Borrower hereby agrees, from time to time, to do and perform any and all
acts and to execute any and all further instruments reasonably requested by the Lender more fully to effect the purposes of this Agreement and the issuance of the Letters of Credit hereunder. 
  

2.21.  
Letter of Credit Applications. 
  
 The representations, warranties and covenants by the Borrower
under, and rights and remedies of the Lender under, any Letter of Credit application (a “Letter of Credit Application”) relating to any Letter of Credit are in addition to, and not in limitation or derogation of, representations,
warranties and covenants by the Borrower under, and rights and remedies of the Lender under, this 
 

 30 

 Agreement, the Loan Documents, and applicable Law. In the event of any inconsistency between the terms of this Agreement and any Letter of Credit Application,
this Agreement shall prevail. 
  
  
 3.  
REPRESENTATIONS AND WARRANTIES. 
  
 To induce the Lender to enter into this Agreement, the Credit
Parties represent, warrant, covenant and agree as follows: 
  
 3.1.  
Corporate Existence and Qualification. 
  
 Each of the Borrower and the Subsidiary Guarantors is a
corporation duly organized, validly existing and in good standing under the laws of its state of incorporation, with all corporate power and authority and all necessary licenses and permits to own, operate and lease its properties and carry on its
business as now being conducted, and as it may reasonably be expected in the future to be conducted. Each of the Borrower and the Subsidiary Guarantors is duly qualified and authorized to do business and is in good standing in each jurisdiction in
which the nature of its activities or the character of its properties makes qualification necessary, except where the failure to be so qualified would not have a Material Adverse Effect. Schedule 3.1 states as of the date hereof the
jurisdictions where the character of the properties owned or leased by each of the Borrower and the Subsidiary Guarantors or the nature of its business makes qualification to do business as a foreign corporation necessary. 
  
 3.2.  
Authority: Noncontravention. 
  
 The execution, delivery and performance of the obligations of the
Credit Parties set forth in this Agreement, the Notes and the other Loan Documents (a) have been duly authorized by all necessary corporate and/or stockholder action; (b) do not require the consent of any Governmental Authority;
(c) will not violate or result in (and with notice or the lapse of time will not violate or result in) the breach of any provision of any Articles of Incorporation or Bylaws, any material indenture, instrument, agreement or other undertaking
to which any Credit Party is a party or by which any Credit Party is bound, or any order or regulation of any Governmental Authority; and (d) except as provided for in this Agreement, result in the creation of a Lien upon any of the
properties or assets of any Credit Party. When the Loan Documents are executed and delivered, they will constitute legal, valid and binding obligations of the Credit Parties, enforceable against the Credit Parties in accordance with their respective
terms. 
  
 3.3.  
Financial Position: Solvency. 
  
 (a)  The Borrower has heretofore
furnished to the Lender consolidated and consolidating balance sheets as of December 31, 2000 and the related consolidated and consolidating statements of income, cash flows and changes in stockholders’ equity for the fiscal year then ended, as
reported on by Ernst & Young, independent certified public accountant. Such 
 

 31 

 financial statements (including the notes thereto) present fairly in all material respects the financial condition of the Borrower as
of the end of such fiscal year and the results of its operations and cash flows for the fiscal year then ended, all in conformity with GAAP. 
  
 (b)  The Borrower has heretofore furnished to the Lender unaudited interim consolidated and consolidating balance sheets as of June 30, 2001, together with the related consolidated and consolidating
statements of income and cash flows for the applicable calendar periods ending on such date. Such financial statements present fairly in all material respects the financial condition of the Borrower as of the end of such period and the results of
its operations and its cash flows for the period then ended, all in conformity with GAAP, subject to normal and recurring year-end audit adjustments and the lack of complete footnotes. 
  
 (c)  There has been no material adverse change in the business, properties or condition (financial or otherwise) of the Borrower or the Borrower and
its Subsidiaries taken as a whole since the date of the June 30, 2001 financial statements. 
  
 (d)  On and as of the Closing Date and after giving effect to all Loans and other obligations and liabilities being incurred on such date in connection therewith, and on the date of each subsequent Loan or other extension
of credit hereunder and after giving effect to the application of the proceeds thereof in accordance with the terms of the Loan Documents, the Borrower is and will be Solvent. 
  
 3.4.  
Payment of Taxes. 
  
 Each of the Borrower and its Subsidiaries has filed all tax returns and reports
required to be filed by it with the United States Government and/or with all state and local governments, and has paid in full or made adequate provision on its books for the payment of all taxes, interest, penalties, assessments or deficiencies
shown to be due or claimed to be due on or in respect of such tax returns and reports, except to the extent that the validity or amount thereof is being contested in good faith by appropriate proceedings and the non-payment thereof pending such
contest will not result in the execution of any tax lien or otherwise jeopardize the Lender’s interests in any part of the Collateral. 
  
 3.5.  
Accuracy of Submitted Information; Omissions. 
  
 As of the date furnished, all documents,
certificates, information, materials and financial statements furnished or to be furnished to the Lender pursuant to the Agreement or otherwise in connection with a Loan or Letter of Credit (a) are true and correct in all material respects;
(b) do not contain any untrue statement of a material fact; and (c) do not omit any material fact necessary to make the statements contained therein or herein not, in light of the circumstances under

Default or impair any right consequent thereto. 
  
 8.5.  
No Implied Waiver; Cumulative Remedies. 
  
 No course of dealing and no delay or failure of the
Lender in exercising any right, power or privilege under this Agreement or any other Loan Document shall affect any other or future exercise thereof or exercise of any other right, power or privilege; nor shall any single or partial exercise of any
such right, power or privilege or any abandonment or discontinuance of steps to enforce such a right, power or privilege preclude any further exercise thereof or of any other right, power or privilege. The rights and remedies of the Lender under
this Agreement and any other Loan Document are cumulative and not exclusive of any rights or remedies which the Lender would otherwise have hereunder or thereunder, at law, in equity or otherwise.

Document) purportedly made by or on behalf of any Credit Party, and the Lender shall not have any duty to verify the identity or authority of any Person giving such notice. 
  
 8.7.

professional, accounting, evaluation and consulting costs) incurred by the Lender from time to time arising from or relating to (i) the negotiation, preparation, execution, delivery, administration and performance of this Agreement and the
other Loan Documents, (ii) any amendments, modifications, supplements, waivers or consents requested by the Borrower (whether or not ultimately entered into or granted) to this Agreement or any other Loan Document, and (iii) the

 (b)  The
Borrower hereby agrees to pay all stamp, document, transfer, recording, filing, registration, search, sales and excise fees and taxes and all similar impositions now or hereafter payable in connection with this Agreement or any other Loan Documents
or any other documents, instruments or transactions pursuant to or in connection herewith or therewith, and the Borrower agrees to save the Lender harmless from and against any and all present or future claims. liabilities or losses with respect to
or resulting from any omission to pay or delay in paying any such fees, taxes or impositions. 
  
 (c)  The Borrower hereby agrees to reimburse and indemnify each of the Indemnified Parties from and against any and all losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits,
costs or disbursements of any kind or nature whatsoever (including the reasonable and documented fees and disbursements of counsel for such Indemnified Party in connection with any investigative, administrative or judicial proceeding commenced or
threatened, whether or not such Indemnified Party shall be designated a party thereto) that may at any time be imposed on, asserted against or incurred by such Indemnified Party as a result of, or arising out of, or in any way related to or by
reason of, this Agreement or any other Loan Document, any transaction from time to time contemplated hereby or thereby, or any transaction financed in whole or in part or directly or indirectly with the proceeds of any Loan or Letter of Credit (and
without in any way limiting the generality of the foregoing, including any grant of any Lien on any Collateral or any exercise by the Lender of any of its rights or remedies under this Agreement or any other Loan Document) or any Swap Contract; but
excluding any such losses, 
 

 62 

  
 liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits,
costs or disbursements to the extent resulting from the gross negligence or willful misconduct of such Indemnified Party, as finally determined by a court of competent jurisdiction. If and to the extent that the foregoing obligations of the Borrower
under this subsection (c), or any other indemnification obligation of the Borrower hereunder or under any other Loan Document or any Swap Contract, are unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the
payment and satisfaction of such obligations which is permissible under applicable Law. 
  
 8.8.  
Severability. 
  
 The provisions of this Agreement are intended to be severable. If any provision of
this Agreement shall be held invalid or unenforceable in whole or in part in any jurisdiction such provision shall, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without in any manner affecting the
validity or enforceability thereof in any other jurisdiction or the remaining provisions hereof in any jurisdiction. 
  
 8.9.  
Prior Understandings. 
  
 This Agreement and the other Loan Documents supersede all prior and
contemporaneous understandings and agreements, whether written or oral, among the parties hereto relating to the transactions provided for herein and therein. 
  
 8.10.  
Duration; Survival. 
  
 All representations and warranties of the Credit Parties contained herein or
in any other Loan Document or made in connection herewith or therewith shall survive the making of, and shall not be waived by the execution and delivery of, this Agreement or any other Loan Document, any investigation by or knowledge of the Lender,
the making of any Loan, or any other event or condition whatever. All covenants and agreements of the Credit Parties contained herein or in any other Loan Document shall continue in full force and effect from and after the date hereof so long as the
Borrower may borrow hereunder and until payment in full of all Obligations. Without limitation, all obligations of the Credit Parties hereunder or under any other Loan Document to make payments to or indemnify the Lender shall survive the payment in
full of all other Obligations, termination of the Borrower’s right to borrow hereunder, the assignment by the Lender of all of its rights and obligations under this Agreement, and all other events and conditions whatever. 

 
 8.11.  
Counterparts. 
  
 This Agreement may be executed in any number of counterparts and by the different
parties hereto on separate counterparts each of which, when so executed, 
 

 63 

  
 shall be deemed an original, but all such counterparts shall constitute but one and the same instrument. 

 
 8.12.  
Limitation on Payments. 
  
 The parties hereto intend to conform to all applicable Laws in effect
from time to time limiting the maximum rate of interest that may be charged or collected. Accordingly, notwithstanding any other provision hereof or of any other Loan Document, the Borrower shall not be required to make any payment to or for the
account of the Lender, and the Lender shall refund any payment made by the Borrower, to the extent that such requirement or such failure to refund would violate or conflict with nonwaivable provisions of applicable Laws limiting the maximum amount
of interest which may be charged or collected by the Lender. 
  
 8.13.  
Set-Off. 
  
 Each Credit Party hereby agrees that if any Obligation of such Credit Party shall be
due and payable (by acceleration or otherwise), and such Credit Party shall fail to pay the same beyond any cure period with respect thereto, the Lender shall have the right, without notice to such Credit Party, to set-off against and to appropriate
and apply to such Obligation any indebtedness, liability or obligation of any nature owing to such Credit Party by the Lender, including all deposits (whether time or demand, general or special, provisionally credited or finally credited, whether or
not evidenced by a certificate of deposit) now or hereafter maintained by such Credit Party with the Lender, in each case to the maximum extent permitted by Law. Such right shall be absolute and unconditional in all circumstances and, without
limitation, shall exist whether or not the Lender or any other Person shall have given notice or made any demand to such Credit Party or any other Person, whether such indebtedness, obligation or liability owed to such Credit Party is contingent,
absolute, matured or unmatured (it being agreed that the Lender may deem such indebtedness, obligation or liability to be then due and payable at the time of such setoff), and regardless of the existence or adequacy of any collateral, guaranty or
any other security, right or remedy available to the Lender or any other Person. The Lender agrees promptly to notify such Credit Party after any such set-off and application made by the Lender; provided, however, that the failure to
give such notice shall not effect the validity of set-off application. Each Credit Party hereby agrees that any branch, subsidiary or affiliate of the Lender shall have the same rights of set-off as the Lender as provided in this Section 8.13
(regardless of whether such branch, subsidiary or affiliate would otherwise be deemed in privity with or a direct creditor of such Credit Party). The rights provided by this Section 8.13 are in addition to all other rights of set-off and
banker’s lien and all other rights and remedies which the Lender (or any such branch, subsidiary or affiliate) may otherwise have under this Agreement, any other Loan Document, at law or in equity, or otherwise, and nothing in this Agreement or
any other Loan Document shall be deemed a waiver or prohibition of or restriction on the rights of set-off or banker’s lien of any such Person. 
 

 64 

  
 8.14.  
Successors and Assigns; Assignments. 
  
 (a)  Successors and
Assigns.    This Agreement shall be binding upon and inure to the benefit of the Credit Parties, the Lender, all future holders of the Notes, and their respective successors and assigns, except that the Credit Parties may not
assign or transfer any of their rights hereunder or interests herein without the prior written consent of all the Lender, and any purported assignment without such consent shall be void. 
  
 (b)  Assignments.    The Lender may at any time assign all or a portion of its rights and obligations under this Agreement
and the other Loan Documents (including all or any portion of its Commitments and Loans owing to it and any Note held by it) to any Person. Upon such assignment, the purchasing Lender shall be a party hereto and shall have the rights and obligations
of the Lender hereunder, and the Lender shall be released from its obligations under this Agreement to the extent so transferred (and, in the case of an assignment covering all or the remaining portion of the Lender’s rights and obligations
under this Agreement, the Lender shall cease to be a party to this Agreement). 
  
 (c)  Financial and Other Information.    The Credit Parties authorize the Lender to disclose to any transferee and any prospective transferee any and all financial and other information in its
possession concerning the Credit Parties and affiliates which has been or may be delivered to it by or on behalf of the Credit Parties in connection with this Agreement or any other Loan Document or its credit evaluation of the Credit Parties.

  
 8.15.  
Materiality. 
  
 Unless the context clearly indicates to the contrary, determinations regarding the
materiality of any act, event, condition or circumstance shall be in the reasonable judgment of the Lender. 
  
 8.16.  
Governing Law; Arbitration: Waiver of Jury Trial; Limitation of Liability. 
  
 (a)  Governing Law. 
  
 THIS AGREEMENT AND ALL OTHER LOAN DOCUMENTS (EXCEPT TO THE
EXTENT, IF ANY, OTHERWISE EXPRESSLY STATED IN SUCH OTHER LOAN DOCUMENTS) SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF VIRGINIA, WITHOUT REGARD TO CHOICE OF LAW PRINCIPLES. 

 
 (b)  Arbitration; Jury Trial Waiver. 
  
 (i)  THIS PARAGRAPH CONCERNS THE RESOLUTION OF ANY CONTROVERSIES OR CLAIMS BETWEEN ANY 
 

 65 

  
 CREDIT PARTY AND LENDER, WHETHER ARISING IN CONTRACT, TORT OR BY STATUTE, INCLUDING BUT NOT
LIMITED TO CONTROVERSIES OR CLAIMS THAT ARISE OUT OF OR RELATE TO: (I) THIS AGREEMENT (INCLUDING ANY RENEWALS, EXTENSIONS OR MODIFICATIONS); OR (II) ANY DOCUMENT RELATED TO THIS AGREEMENT (COLLECTIVELY A “CLAIM”); 

 
 (ii)  AT THE REQUEST OF ANY CREDIT PARTY OR LENDER, ANY CLAIM SHALL BE RESOLVED BY BINDING ARBITRATION IN
ACCORDANCE WITH THE FEDERAL ARBITRATION ACT (TITLE 9, U.S. CODE) (THE “ACT”). THE ACT WILL APPLY EVEN THOUGH THIS AGREEMENT PROVIDES THAT IT IS GOVERNED BY THE LAW OF A SPECIFIED STATE; 
  
 (iii)  ARBITRATION PROCEEDINGS WILL BE DETERMINED IN ACCORDANCE WITH THE ACT, THE APPLICABLE RULES AND PROCEDURES FOR THE
ARBITRATION OF DISPUTES OF JAMS OR ANY SUCCESSOR THEREOF (“JAMS”), AND THE TERMS OF THIS PARAGRAPH. IN THE EVENT OF ANY INCONSISTENCY, THE TERMS OF THIS PARAGRAPH SHALL CONTROL; 
  

(iv)  THE ARBITRATION SHALL BE ADMINISTERED BY JAMS AND CONDUCTED IN ANY U.S. STATE WHERE REAL OR TANGIBLE PERSONAL PROPERTY COLLATERAL FOR THIS
CREDIT IS LOCATED OR IF THERE IS NO SUCH COLLATERAL, IN THE COMMONWEALTH OF VIRGINIA. ALL CLAIMS SHALL BE DETERMINED BY ONE ARBITRATOR; HOWEVER, IF CLAIMS EXCEED $5,000,000, UPON THE REQUEST OF ANY PARTY, THE CLAIMS SHALL BE DECIDED BY THREE
ARBITRATORS. ALL ARBITRATION HEARINGS SHALL COMMENCE WITHIN 90 DAYS OF THE DEMAND FOR ARBITRATION AND CLOSE WITHIN 90 DAYS OF COMMENCEMENT AND THE AWARD OF THE ARBITRATOR(S) SHALL BE ISSUED WITHIN 30 DAYS OF THE CLOSE OF THE HEARING. HOWEVER, THE
ARBITRATOR(S), UPON A SHOWING OF GOOD CAUSE, MAY EXTEND THE COMMENCEMENT OF THE HEARING FOR UP TO AN ADDITIONAL 60 DAYS. THE ARBITRATOR(S) SHALL PROVIDE A CONCISE WRITTEN STATEMENT OF REASONS FOR THE AWARD. THE ARBITRATION AWARD MAY BE SUBMITTED TO
ANY COURT HAVING JURISDICTION TO BE CONFIRMED AND ENFORCED; 
 

 66 

  
 (v)  THE ARBITRATOR(S) WILL HAVE THE AUTHORITY TO DECIDE WHETHER
ANY CLAIM IS BARRED BY THE STATUTE OF LIMITATIONS AND, IF SO, TO DISMISS THE ARBITRATION ON THAT BASIS. FOR PURPOSES OF THE APPLICATION OF THE STATUTE OF LIMITATIONS, THE SERVICE ON JAMS UNDER APPLICABLE JAMS RULES OF A NOTICE OF CLAIM IS THE
EQUIVALENT OF THE FILING OF A LAWSUIT. ANY DISPUTE CONCERNING THIS ARBITRATION PROVISION OR WHETHER A CLAIM IS ARBITRABLE SHALL BE DETERMINED BY THE ARBITRATOR(S). THE ARBITRATOR(S) SHALL HAVE THE POWER TO AWARD LEGAL FEES PURSUANT TO THE TERMS OF
THIS AGREEMENT; 
  
 (vi)  THIS PARAGRAPH DOES NOT LIMIT THE RIGHT OF ANY CREDIT PARTY OR LENDER
TO: (I) EXERCISE SELF-HELP REMEDIES, SUCH AS BUT NOT LIMITED TO, SETOFF; (II) INITIATE JUDICIAL OR NONJUDICIAL FORECLOSURE AGAINST ANY REAL OR PERSONAL PROPERTY COLLATERAL; (III) EXERCISE ANY JUDICIAL OR POWER OF SALE RIGHTS, OR (IV) ACT IN A COURT
OF LAW TO OBTAIN AN INTERIM REMEDY, SUCH AS BUT NOT LIMITED TO, INJUNCTIVE RELIEF, WRIT OF POSSESSION OR APPOINTMENT OF A RECEIVER, OR ADDITIONAL OR SUPPLEMENTARY REMEDIES; AND 
  
 (vii)  BY AGREEING TO BINDING ARBITRATION, THE PARTIES IRREVOCABLY AND VOLUNTARILY WAIVE ANY RIGHT THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
CLAIM. FURTHERMORE, WITHOUT INTENDING IN ANY WAY TO LIMIT THIS AGREEMENT TO ARBITRATE, TO THE EXTENT ANY CLAIM IS NOT ARBITRATED, THE PARTIES IRREVOCABLY AND VOLUNTARILY WAIVE ANY RIGHT THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF SUCH CLAIM. THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES ENTERING INTO THIS AGREEMENT. 
  
 (c)  Limitation of Liability. 
  
 TO THE FULLEST EXTENT PERMITTED BY LAW, NO CLAIM
MAY BE MADE BY ANY CREDIT PARTY AGAINST THE LENDER OR ANY AFFILIATE, DIRECTOR, OFFICER, EMPLOYEE, ATTORNEY OR AGENT OF IT FOR ANY SPECIAL, INCIDENTAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES IN RESPECT OF ANY 
 

 67 

  
 CLAIM ARISING FROM OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY
STATEMENT, COURSE OF CONDUCT, ACT, OMISSION, OR EVENT OCCURRING IN CONNECTION HEREWITH OR THEREWITH (WHETHER FOR BREACH OF CONTRACT, TORT OR ANY OTHER THEORY OF LIABILITY). EACH CREDIT PARTY HEREBY WAIVES, RELEASES AND AGREES NOT TO SUE UPON ANY
CLAIM FOR ANY SUCH DAMAGES, WHETHER SUCH CLAIM PRESENTLY EXISTS OR ARISES HEREAFTER AND WHETHER OR NOT SUCH CLAIM IS KNOWN OR SUSPECTED TO EXIST IN ITS FAVOR.

 WHEREAS, the obligation of the Lender to extend such credit under the Credit Agreement is subject to the condition, among others, that each Debtor grant to and create in favor of
the Lender a security interest in all assets of each such Debtor as hereinafter provided; 
  
 NOW, THEREFORE, in
consideration of the Debt (as hereinafter defined) and other good and valuable consideration, receipt and sufficiency of which are hereby acknowledged by the Debtors, and in order to induce the Lender to extend credit under the Credit Agreement, the
parties hereto, intending to be legally bound hereby, covenant and agree as follows: 
  
 1.  Certain
Definitions.    In addition to the words and terms defined elsewhere in this Agreement, the following words and terms shall have the following meanings, respectively, unless the context hereof otherwise clearly requires:

  
 Words and terms defined in the Credit Agreement shall, unless the context hereof clearly otherwise requires,

the Debt is created, each Debtor hereby agrees that the Lender shall have, and each Debtor hereby grants to and creates in favor of the Lender, a security interest under the UCC in and to the Collateral.

Lender by this Agreement, the Credit Agreement, the Notes and the other Loan Documents, the Lender shall have all the rights and remedies of a secured party under the UCC. 
  
 4.  Certain Provisions Applicable to the Collateral.    The parties agree that, at all times during the term of this Agreement, the following
provisions shall apply to the Collateral: 
  
 (a)  Each Debtor represents and warrants that it has and
will have good and marketable title to the Collateral from time to time owned or acquired by it, free and clear of all liens, encumbrances and security interests, except Permitted Liens. Each Debtor will take all reasonable steps to defend such
title against the claims and demands of all persons whomsoever. 
  
 (b)  Each Debtor represents and
warrants to the Lender that it does not currently own or hold any Documents, Instruments or Chattel Paper. In order to perfect the security interest granted by each Debtor hereby, each Debtor shall deliver to the Lender possession of any Documents,
Instruments and Chattel Paper hereafter acquired by such Debtor (duly endorsed by such Debtor in blank), promptly upon its acquisition of the same. 
  
 (c)  Except as may be permitted by the Credit Agreement, the Debtors will not (i) sell, lease, transfer or otherwise dispose of any of the
Collateral, (ii)borrow against the Collateral from any person, firm or corporation other than from the Lender pursuant to the Credit Agreement, (iii) create, incur, assume or suffer to exist any Lien on any of the
Collateral, (iv)permit any levy or attachment to be made against any of the Collateral except any levy or attachment relating to this Agreement, (v)permit any financing statement to be on file with respect to any of the
Collateral, except financing statements in favor of the Lender, or (vi) 
 

 4 

 permit any notice to be filed under the Assignment of Claims Act with respect to any of the Collateral, except for any such notice in
favor of the Lender. 
  
 (d)  Risk of loss of, damage to or destruction of the Collateral is on the
Debtors. The Debtors will insure the Collateral against such risks and casualties and in such amounts and with such insurers as are specified in the Credit Agreement. All such policies of insurance shall contain loss payable clauses in favor of the
Debtors and the Lender as their respective interests may appear, and such policies or certificates evidencing the same shall be deposited with the Lender immediately upon the request of the Lender. Each Debtor agrees to notify the Lender promptly of
any notice of cancellation of any such policy and agrees not to cancel, mortgage, pledge, hypothecate, sell, transfer or assign its interest in any such insurance or any rights to cancel such insurance or to obtain the return of the unearned
premiums therefor to any person other than the Lender. If any Debtor fails to effect and keep in full force and effect such insurance or fails to pay the premiums thereon when due, the Lender may do so for the account of such Debtor and add the cost
thereof to the Debt, and the same shall be payable to the Lender on demand (unless it has obtained reasonably satisfactory substitute insurance policies prior to the Lender’s obtaining such insurance). Each Debtor hereby assigns and sets over
unto the Lender all moneys which may become payable on account of such insurance, including, without limitation, any return of unearned premiums which may be due upon cancellation of any such insurance, and directs the insurers to pay the Lender any
amount so due. Following the occurrence and during the continuation of an Event of Default, the Lender, its officers, employees and authorized agents, are hereby irrevocably appointed attorneys-in-fact of each Debtor to endorse any draft or check
which may be payable to such Debtor in order to collect the proceeds of such insurance or any return of unearned premiums. Such proceeds shall be applied to the payment or prepayment of the Debt in such order as the Lender may determine In
accordance with the Credit Agreement. Any balance of insurance proceeds remaining in the possession of the Lender after payment in full of the Debt shall be paid to the Borrower or order. 
  
 (e)  Each Debtor assumes full responsibility for taking any and all necessary steps to preserve rights in respect of the Accounts, Chattel Paper, Contract
Rights, Instruments, Documents and General Intangibles against all account debtors, obligors and other persons. 
  
 (f)  Upon the occurrence and during the continuance of any Event of Default, each Debtor shall promptly upon demand by the Lender assemble the Equipment and Inventory and make it available to the Lender at the place or places to
be designated by the Lender which shall be reasonably convenient to all parties. The right of the Lender under this subsection (f) to have the Equipment and Inventory assembled and made available to it is of the essence of this Agreement

 

 5 

 and the Lender may, at its election, enforce such right by a bill In equity for specific performance. 
  
 (g)  If any Debtor fails to maintain each item of Equipment and Inventory in accordance with the requirements specified in
the Credit Agreement, the Lender may pay the cost of such repairs or maintenance and such taxes, levies or other impositions for the account of such Debtor (and shall provide notice to such Debtor of such payments) and add the amount thereof to the
Debt, and the same shall be payable to the Lender on demand. 
  
 The Lender shall have no duty as to the collection or protection of the Collateral or any
part thereof or any income thereon, or as to the preservation of any rights pertaining thereto, beyond exercising reasonable care in the custody of any Collateral actually in the possession of the Lender. The Lender shall be deemed to have exercised
reasonable care in the custody and preservation of such of the Collateral as may be in its possession if it takes such action for that purpose as any Debtor shall request in writing, provided that such requested action shall not, in the judgment of
the Lender, impair the Lender’s security interest in the Collateral or its rights in, or the value of, the Collateral, and provided further that such written request is received by the Lender in sufficient time to permit it to take the
requested action. 
  
 5.  Certain Additional Matters.    Each Debtor represents, warrants,
covenants and agrees that: 
  
 (a)  This Agreement is effective to create in favor of the Lender for
the benefit of the Lender a legal, valid and enforceable security interest in all right, title and interest in and to the Collateral. When the financing statements indicated in the Perfection Certificate have been filed in the offices in the
jurisdictions listed in the Perfection Certificate, this Security Agreement will constitute a fully perfected Lien on, and security interest in and to, the Collateral, subject only to Permitted Liens, and prior to all other Liens. Each Debtor shall,
at its expense, promptly take any and all such other or further acts as the Lender may deem necessary or advisable to execute, acknowledge and deliver, and thereafter register, file or record, any document or instrument supplemental to or
confirmatory of this Agreement (including financing statements and continuation statements) which may be necessary or desirable to preserve, perfect and continue perfected the Lender’s security interest in the Collateral, including, without
limitation, the signing of financing and other similar statements. 
  
 (b)  Each Debtor has previously
delivered to the Lender a certificate signed by such Debtor and entitled “Perfection Certificate” (the “Perfection Certificate”). Each Debtor represents and warrants to the Lender as follows: (i) such Debtor’s
exact legal name is that indicated on the Perfection Certificate and on the signature page hereof, (ii) such Debtor is an organization of the type and organized in the jurisdiction set forth in the Perfection Certificate, (iii) the 

 6 

 Perfection Certificate accurately sets forth such Debtor’s organizational identification number or accurately states that such
Debtor has none, (iv) the Perfection Certificate accurately sets forth such Debtor’s place of business or, if more than one, its chief executive office as well as such Debtor’s mailing address if different and (v) all other information set
forth on the Perfection Certificate pertaining to such Debtor is accurate and complete. 
  
 (c)  Each
Debtor covenants with the Lender as follows: (a) without providing at least 30 days prior written notice to the Lender, such Debtor will not change its name, its place of business or, if more than one, chief executive office, or its mailing address
or organizational identification number if it has one, or the locations of the Collateral from those listed on the Perfection Certificate, (b) if such Debtor does not have an organizational identification number and later obtains one, such Debtor
shall forthwith notify the Lender of such organizational identification number, and (c) such Debtor will not change its type of organization, jurisdiction of organization or other legal structure. 
  
 (d)  The Lender is hereby appointed attorney-in-fact for each Debtor to do all acts and things which the Lender may deem
necessary or advisable to preserve, perfect and continue perfected the Lender’s security Interest in the Collateral. 
  
 (e)  Each Debtor hereby irrevocably authorizes the Lender at any time and from time to time to file in any UCC jurisdiction any initial financing statements and amendments thereto that (i) indicate the
Collateral (A) as all assets of such Debtor or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the UCC, or (B) as being of an equal or lesser scope or with
greater detail, and (ii) contain any other information required by part 5 of Article 9 of the UCC for the sufficiency or filing office acceptance of any financing statement or amendment, including (A) whether such Debtor is an organization, the type
of organization and any organization identification number issued to such Debtor and, (B) in the case of a financing statement filed as a fixture filing or indicating Collateral as as-extracted collateral or timber to be cut, a sufficient
description of real property to which the Collateral relates. Each Debtor agrees to furnish any such information to the Lender promptly upon request. 
  
 6.  Cash Management. 
  
 (a)  Each Debtor will
deposit, or cause to be deposited, all Items of Payment to a bank account designated by the Lender and from which the Lender alone has power of access and withdrawal (the “Collateral Account”). Each deposit shall be made not
later than the next Business Day after the date of receipt of the Items of Payment. The Items of Payment shall be deposited in precisely the form received, except for the endorsements of such Debtor where necessary to permit the collection of any
such Items of Payment, such Debtor hereby agreeing 
 

 7 

 to make such endorsement. In the event such Debtor shall fail to do so, the Lender is hereby authorized by such Debtor to make the
endorsement in the name of such Debtor. Prior to such a deposit, such Debtor will not commingle any Items of Payment with any of the other funds or property of such Debtor, but will hold them separate and apart in trust and for the account of the
Lender. 
  
 (b)  In addition, if so directed by the Lender, following and during the continuance of an
Event of Default, each Debtor shall direct the mailing of all Items of Payment from its account debtors to a post-office box designated by the Lender, or to such other additional or replacement post-office boxes pursuant to the request of the Lender
from time to time (collectively, the “Lockbox”). The Lender shall have unrestricted and exclusive access to the Lockbox. 
  
 (c)  Each Debtor hereby authorizes the Lender to inspect all Items of Payment, endorse all Items of Payment in the name of such Debtor, and deposit Items of
Payment in the Collateral Account. The Lender reserves the right, exercised in its sole and absolute discretion from time to time, to provide to the Collateral Account credit prior to final collection of an Item of Payment and to disallow credit for
any Item of Payment which is unsatisfactory to the Lender. In the event Items of Payment are returned to the Lender for any reason whatsoever, the Lender may, in the exercise of its discretion from time to time, forward such Items of Payment a
second time. Any returned Items of Payment shall be charged back to the Collateral Account, the Loan Account or other account, as appropriate. 
  
 (d)  The Lender will apply the whole or any part of the collected funds credited to the Collateral Account against the outstanding balance of the Revolving
Credit Facility Loans and Obligations related thereto until paid in full or credit such collected funds to the depository account of the Debtors with the Lender (or an Affiliate of the Lender), as provided in the Autoborrow Service Agreement. During
the period in which an Event of Default exists and is continuing, the Lender shall have the option to apply the whole or any part of the collected funds against the outstanding balance of the Term Loan or any Obligations related thereto.

  
 7.  Events of Default.    If one or more of the Events of Default shall occur and be
continuing or shall exist, then and in any such event, the Lender shall have such rights and remedies in respect of the Collateral or any part thereof as are provided by the UCC and such other rights and remedies in respect thereof which it may have
at law or in equity or under this Agreement, including, without limitation, the right to (i) enter any premises where Equipment or Inventory is located and take possession of the same without demand or notice and without prior judicial
hearing or legal proceedings, which each Debtor hereby expressly waives, and/or (ii) sell all or any portion of the Collateral at any broker’s board or at public or private sale, without prior notice to any Debtor except as
otherwise required by law (and if notice is required by law, after ten days’ 
 

 8 

 prior written notice), at such time or times and in such manner and upon such terms, whether for cash or on credit, as the Lender in its reasonable discretion
may determine. The Lender shall apply the Proceeds of any such sale and any Proceeds received by the Lender first to the payment of the reasonable costs and expenses incurred by the Lender in connection with such sale or collection, including,
without limitation, reasonable attorneys’ fees and legal expenses, second to the payment of the Debt in such order as the Lender may determine in accordance with the Credit Agreement until the Debt has been paid in full, and then to pay the
balance, if any, as required by law. 
  
 8.  Amendments.    The provisions of this Agreement
may from time to time be waived, modified, supplemented or amended with the written consent of the Debtors and the Lender. Any waiver, permit, consent or approval of any kind or character on the part of the Lender of or to any breach or default
under this Agreement or any such waiver of any provision or condition of this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing. 
  
 9.  Defeasance.    Upon the payment in full of the Debt, this Agreement shall terminate and be of no further force or effect; provided,
however, that this Agreement shall not terminate so long as the Borrower may borrow under, or cause Letters of Credit to be issued under the Credit Agreement or any Letter of Credit remains outstanding. In connection with such termination,
the Lender agrees to execute, at the Debtors’ expense, such agreements and financing statements (including UCC-3’s) as the Debtors reasonably request in order to evidence such termination. Until such time, however, this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. 
  
 10.  Severability.    If any provision of this Agreement shall for any reason be held invalid or unenforceable, such invalidity or unenforceability shall not affect any other provision hereof, but this
Agreement shall be construed as if such invalid or unenforceable provision had never been contained herein. 
  
 11.  Waiver.    No delay or failure on the part of the Lender in exercising any right, remedy, power or privilege hereunder shall operate as a waiver thereof or of any other right, remedy, power or
privilege of the Lender hereunder or under the Credit Agreement or any instrument or instruments now or hereafter evidencing the Debt; nor shall any single or partial exercise of any such right, remedy, power or privilege preclude any other or
further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights and remedies of the Lender under this Agreement are cumulative and not exclusive of any rights or remedies which it might otherwise have.

  
 12.  Indemnification.    The Debtors will indemnify and save and hold the Lender harmless
from and against any and all claims, damages, losses, liabilities or judgments which may be incurred or sustained by the Lender or asserted against the Lender, directly or indirectly, in connection with the existence of or the lawful exercise of any
of the security rights with respect to the Collateral, except for matters which may result from 
 

 9 

 the gross negligence or willful misconduct of the Lender. The covenants contained in this paragraph shall survive the termination of the other provisions of
this Agreement. In the event of any action at law or suit in equity in relation to this Agreement, the Debtors, in addition to all other sums which they may be required to pay, will pay a reasonable sum for attorneys’ fees incurred by the
Lender in connection with such action or suit and all other expenses of collection. 
  
 13.  Survival.    All representations, warranties, covenants and agreements of the Debtors contained herein or made in writing in connection herewith shall survive the execution and delivery of this
Agreement and shall continue in full force and effect from and after the date hereof until payment in full of the Debt. 
  
 14.  Notices.    All notices hereunder shall be given in accordance with, and become effective as provided by, Section 8.6 of the Credit Agreement. 
  

15.  ARBITRATION. 
  
 A.  THIS PARAGRAPH CONCERNS THE RESOLUTION OF ANY CONTROVERSIES OR CLAIMS BETWEEN ANY DEBTOR AND LENDER, WHETHER ARISING IN CONTRACT, TORT OR BY STATUTE, INCLUDING BUT NOT LIMITED TO CONTROVERSIES OR CLAIMS THAT ARISE OUT OF OR
RELATE TO: (I) THIS AGREEMENT (INCLUDING ANY RENEWALS, EXTENSIONS OR MODIFICATIONS); OR (II) ANY DOCUMENT RELATED TO THIS AGREEMENT (COLLECTIVELY A “CLAIM”). 
  
 B.  AT THE REQUEST OF ANY DEBTOR OR LENDER, ANY CLAIM SHALL BE RESOLVED BY BINDING ARBITRATION IN ACCORDANCE WITH THE FEDERAL ARBITRATION ACT (TITLE 9,
U.S. CODE) (THE “ACT”). THE ACT WILL APPLY EVEN THOUGH THIS AGREEMENT PROVIDES THAT IT IS GOVERNED BY THE LAW OF A SPECIFIED STATE. 
  
 C.  ARBITRATION PROCEEDINGS WILL BE DETERMINED IN ACCORDANCE WITH THE ACT, THE APPLICABLE RULES AND PROCEDURES FOR THE ARBITRATION OF DISPUTES OF JAMS OR
ANY SUCCESSOR THEREOF (“JAMS”), AND THE TERMS OF THIS PARAGRAPH. IN THE EVENT OF ANY INCONSISTENCY, THE TERMS OF THIS PARAGRAPH SHALL CONTROL. 
  
 D.  THE ARBITRATION SHALL BE ADMINISTERED BY JAMS AND CONDUCTED IN ANY U.S. STATE WHERE REAL OR TANGIBLE PERSONAL PROPERTY COLLATERAL FOR THIS CREDIT IS
LOCATED OR IF THERE IS NO SUCH COLLATERAL, IN THE COMMONWEALTH OF VIRGINIA. ALL CLAIMS SHALL BE DETERMINED BY ONE ARBITRATOR; HOWEVER, IF CLAIMS EXCEED $5,000,000, UPON THE REQUEST OF ANY PARTY, THE CLAIMS SHALL BE DECIDED BY THREE ARBITRATORS. ALL
ARBITRATION HEARINGS SHALL COMMENCE WITHIN 90 DAYS OF THE DEMAND FOR ARBITRATION 
 

 10 

 AND CLOSE WITHIN 90 DAYS OF COMMENCEMENT AND THE AWARD OF THE ARBITRATOR(S) SHALL BE ISSUED WITHIN 30 DAYS OF THE CLOSE OF THE
HEARING. HOWEVER, THE ARBITRATOR(S), UPON A SHOWING OF GOOD CAUSE, MAY EXTEND THE COMMENCEMENT OF THE HEARING FOR UP TO AN ADDITIONAL 60 DAYS. THE ARBITRATOR(S) SHALL PROVIDE A CONCISE WRITTEN STATEMENT OF REASONS FOR THE AWARD. THE ARBITRATION
AWARD MAY BE SUBMITTED TO ANY COURT HAVING JURISDICTION TO BE CONFIRMED AND ENFORCED. 
  
 E.  THE ARBITRATOR(S) WILL HAVE THE AUTHORITY TO DECIDE WHETHER ANY CLAIM IS BARRED BY THE STATUTE OF LIMITATIONS AND, IF SO, TO DISMISS THE ARBITRATION ON THAT BASIS. FOR PURPOSES OF THE APPLICATION OF THE STATUTE OF
LIMITATIONS, THE SERVICE ON JAMS UNDER APPLICABLE JAMS RULES OF A NOTICE OF CLAIM IS THE EQUIVALENT OF THE FILING OF A LAWSUIT. ANY DISPUTE CONCERNING THIS ARBITRATION PROVISION OR WHETHER A CLAIM IS ARBITRABLE SHALL BE DETERMINED BY THE
ARBITRATOR(S). THE ARBITRATOR(S) SHALL HAVE THE POWER TO AWARD LEGAL FEES PURSUANT TO THE TERMS OF THIS AGREEMENT. 
  
 F.  THIS PARAGRAPH DOES NOT LIMIT THE RIGHT OF ANY DEBTOR OR LENDER TO: (I) EXERCISE SELF-HELP REMEDIES, SUCH AS BUT NOT LIMITED TO, SETOFF; (II) INITIATE JUDICIAL OR NONJUDICIAL FORECLOSURE AGAINST ANY REAL OR PERSONAL
PROPERTY COLLATERAL; (III) EXERCISE ANY JUDICIAL OR POWER OF SALE RIGHTS, OR (IV) ACT IN A COURT OF LAW TO OBTAIN AN INTERIM REMEDY, SUCH AS BUT NOT LIMITED TO, INJUNCTIVE RELIEF, WRIT OF POSSESSION OR APPOINTMENT OF A RECEIVER, OR ADDITIONAL OR
SUPPLEMENTARY REMEDIES. 
  
 G.  BY AGREEING TO BINDING ARBITRATION, THE PARTIES IRREVOCABLY AND
VOLUNTARILY WAIVE ANY RIGHT THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM. FURTHERMORE, WITHOUT INTENDING IN ANY WAY TO LIMIT THIS AGREEMENT TO ARBITRATE, TO THE EXTENT ANY CLAIM IS NOT ARBITRATED, THE PARTIES IRREVOCABLY AND VOLUNTARILY
WAIVE ANY RIGHT THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF SUCH CLAIM. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES ENTERING INTO THIS AGREEMENT. 
  
 16.  Governing Law.    The UCC shall govern the attachment, perfection and the effect of attachment and perfection of the Lender’s security
interest in the Collateral and the rights, duties and obligations of the Lender and the Debtors with respect thereto. This Agreement shall be deemed to be a contract under the laws of the Commonwealth of Virginia and the execution and delivery
hereof and, to the extent not inconsistent with the preceding sentence, the terms and provisions hereof shall be governed by and construed in accordance with the laws of said 
 

 11 

 Commonwealth. Unless the context otherwise requires, all terms used herein which are defined in the UCC shall have the meanings therein stated. 

 
 17.  Headings.    The headings of this Agreement are for convenience only and shall not be construed as
a part of this Agreement. 
  
 18.  Counterparts.    This Agreement may be executed in
counterparts, each of which when so executed shall together constitute one and the same agreement.
