 2.2 Revolving Loans. Subject to the terms and conditions set forth herein, each Revolving
Credit Lender severally agrees to make Revolving Loans to the Borrowers, from time to time until the Commitment Termination Date in an aggregate principal amount at any one time outstanding that will not result in (a) such Revolving Credit
Lender’s Revolving Credit Exposure exceeding such Revolving Credit Lender’s Revolving Commitment or (b) the aggregate amount of the Revolving Credit Exposure outstanding exceeding the Aggregate Revolving Credit Commitments.

 2.3 Procedure for Revolving Loan Borrowings. The Company, on behalf of the Borrowers, shall give the Administrative Agent a
Notice of Borrowing with respect to each Revolving Loan Borrowing (x) prior to 11:00 a.m. on the requested date of each Base Rate Borrowing or Index Rate Borrowing (which shall be a Business Day) and (y) prior to 12:00 noon three
(3) Business Days prior to the requested date of each LIBOR Borrowing. Each Notice of Borrowing under this Section shall be irrevocable and shall specify: (i) the aggregate principal amount of such Revolving Loan Borrowing, (ii) the
date of such Revolving Loan Borrowing (which shall be a Business Day), (iii) the Type of the Revolving Loans comprising such Borrowing, and (iv) in the case of a LIBOR Borrowing, the duration of the initial Interest Period applicable
thereto (subject to the provisions of the definition of Interest Period). Each Revolving Loan Borrowing shall consist entirely of Base Rate Loans, Index Rate Loans or LIBOR Loans, as the Company may request, provided, that on the Closing Date
all Revolving Loans shall be Index Rate Loans. Promptly following the receipt of a Notice of Borrowing in accordance with this Section, the Administrative Agent shall advise each Revolving Credit Lender of the details thereof and the amount of such
Revolving Credit Lender’s Revolving Loan to be made as part of the requested Revolving Loan Borrowing. Each Borrower appoints the Company as its agent to request and receive the proceeds of the Revolving Loans on behalf of all Borrowers. The
Company agrees to distribute the proceeds of the Revolving Loans among the Borrowers when and as needed by the Borrowers for working capital. Revolving Loans may be requested by those individuals designated by the Company from time to time in
written instruments delivered to the Administrative Agent; provided, however, that the Borrowers shall remain liable with respect to any Revolving Loan disbursed by any Lender in good faith hereunder, even if such Revolving Loan is
requested by an individual who has not been so designated. The proceeds of each Revolving Loan will be credited to a deposit account maintained with the Administrative Agent by the Company by 3:00 p.m. on the date of the requested Borrowing.

(ii) the difference between the Aggregate Revolving Commitments and the aggregate Revolving Credit Exposures of all Revolving Credit Lenders; provided, that the Swingline Lender shall not be required to make a Swingline Loan to refinance an
outstanding Swingline Loan. The Borrowers shall be entitled to borrow, repay and reborrow Swingline Loans in accordance with the terms and conditions of this Agreement. 
  

 24 








 2.5 Procedure for Swingline Borrowing. 
 (a) The Swingline Lender agrees to make Swingline Loans to the Company from time to time in accordance with the treasury and cash management
services and products provided to the Company by the Swingline Lender (the “Cash Management Swingline Loans”). For other Swingline Loans, the Company, on behalf of the Borrowers, shall give the Administrative Agent a Notice of Borrowing
with respect to each Swingline Loan prior to 12:00 noon on the requested date of each Swingline Borrowing. Each Notice of Borrowing under this Section shall be irrevocable and shall specify: (i) the principal amount of such Swingline Loan,
(ii) the date of such Swingline Loan (which shall be a Business Day), (iii) the Type of such Swingline Loan and (iv) the account of the Company to which the proceeds of such Swingline Loan should be credited. The Administrative Agent
will promptly advise the Swingline Lender of each such request and the details thereof. Each Cash Management Swingline Loan shall be made initially as an Index Rate Loan, and each other Swingline Loan shall be made as a Base Rate Loan or an Index
Rate Loan. The Swingline Lender will make the proceeds of each Swingline Loan available to the Borrowers in Dollars in immediately available funds at the account specified by the Company in the applicable request not later than 2:00 p.m. on the
requested date of such Swingline Loan. 
 (b) The Swingline Lender, at any time and from time to time in its sole
discretion, may, on behalf of the Borrowers (each of which hereby irrevocably authorizes and directs the Swingline Lender to act on its behalf), give a Notice of Borrowing with respect to Revolving Loans to the Administrative Agent and the Company
requesting the Revolving Credit Lenders (including the Swingline Lender) to make Index Rate Loans in an amount equal to the unpaid principal amount of any Swingline Loan. Each Revolving Credit Lender will make the proceeds of its Index Rate Loan
included in such Borrowing available to the Administrative Agent for the account of the Swingline Lender in accordance with Section 2.8, which will be used solely for the repayment of such Swingline Loan. 
 (c) If for any reason an Index Rate Borrowing may not be (as determined in the sole discretion of the Administrative Agent), or is not, made in
accordance with the foregoing provisions, then such Swingline Loan shall automatically be converted to a Index Rate Loan, upon notice from the Swingline Lender to the Administrative Agent and the Company, and each Revolving Credit Lender (other than
the Swingline Lender) shall purchase an undivided participating interest in such Swingline Loan in an amount equal to its Revolving Credit Percentage thereof on the date that such Index Rate Borrowing should have occurred. On the date of such
required purchase, each Revolving Credit Lender shall promptly transfer, in immediately available funds, the amount of its participating interest to the Administrative Agent for the account of the Swingline Lender. 
 (d) Each Revolving Credit Lender’s obligation to make an Index Rate Loan pursuant to Section 2.5(b) or to purchase the participating
interests pursuant to Section 2.5(c) 
  

 25 








 shall be absolute and unconditional and shall not be affected by any circumstance, including without limitation
(i) any setoff, counterclaim, recoupment, defense or other right that such Revolving Credit Lender or any other Person may have or claim against the Swingline Lender, any Borrower or any other Person for any reason whatsoever, (ii) the
existence of a Default or an Event of Default or the termination of any Revolving Credit Lender’s Revolving Commitment, (iii) the existence (or alleged existence) of any event or condition which has had or could reasonably be expected to
have a Material Adverse Effect, (iv) any breach of this Agreement or any other Loan Document by any Borrower, the Administrative Agent or any Revolving Credit Lender or (v) any other circumstance, happening or event whatsoever, whether or
not similar to any of the foregoing: provided, however, that the obligation of each Revolving Credit Lender to make any such Index Rate Loan or purchase any such participating interest is subject to the condition that the Swing
Line Lender believed in good faith that all conditions under Section 8.2 were satisfied at the time the Swing Line Loan was made. If such amount is not in fact made available to the Swingline Lender by any Revolving Credit Lender, the Swingline
Lender shall be entitled to recover such amount on demand from such Revolving Credit Lender, together with accrued interest thereon for each day from the date of demand thereof at the Federal Funds Rate. Until such time as such Revolving Credit
Lender makes its required payment, the Swingline Lender shall be deemed to continue to have outstanding Swingline Loans in the amount of the unpaid participation for all purposes of the Loan Documents. In addition, such Revolving Credit Lender shall
be deemed to have assigned any and all payments made of principal and interest on its Loans and any other amounts due to it hereunder, to the Swingline Lender to fund the amount of such Revolving Credit Lender’s participation interest in such
Swingline Loans that such Revolving Credit Lender failed to fund pursuant to this Section, until such amount has been purchased in full. 
 2.6 Letters of Credit. 
 (a) Until the Commitment Termination Date, the Issuing Bank, in reliance upon the
agreements of the other Revolving Credit Lenders pursuant to Section 2.6(d), agrees to issue, at the request of the Company, Letters of Credit for the account of the Borrowers on the terms and conditions hereinafter set forth; provided,
that (i) each Letter of Credit shall expire on the earlier of (A) the date one year after the date of issuance of such Letter of Credit (or in the case of any renewal or extension thereof, one year after such renewal or extension) and
(B) the date that is five (5) Business Days prior to the Commitment Termination Date (except pursuant to a clause whereby the Issuing Bank is entitled to terminate the Letter of Credit on an annual basis by giving prior written notice to
the beneficiary thereof in accordance with the written terms of such Letter of Credit); (ii) each Letter of Credit shall be in a stated amount of at least $25,000; and (iii) the Borrowers may not request any Letter of Credit, if, after
giving effect to such issuance (A) the aggregate LC Exposure would exceed the LC Commitment, or (B) the aggregate Revolving Credit Exposure of all Lenders would exceed the Aggregate Revolving Commitment Amount. Upon the issuance of each
Letter of Credit each Revolving Credit Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Issuing Bank without recourse a participation in such Letter of Credit equal to such Revolving Credit
Lender’s Revolving Credit Percentage of the aggregate amount available to be drawn under such Letter of Credit. Each issuance of a Letter of Credit shall be deemed to utilize the Revolving Commitment of each Revolving Credit Lender by an amount
equal to the amount of such participation. 
  

 26 








 (b) To request the issuance of a Letter of Credit (or any amendment, renewal or extension of an
outstanding Letter of Credit), the Company shall give the Issuing Bank and the Administrative Agent irrevocable written notice at least three (3) Business Days prior to the requested date of such issuance specifying the date (which shall be a
Business Day) such Letter of Credit is to be issued (or amended, extended or renewed, as the case may be), the expiration date of such Letter of Credit, the amount of such Letter of Credit, the name and address of the beneficiary thereof and such
other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. In addition to the satisfaction of the conditions precedent to the effectiveness of this Agreement, the issuance of such Letter of Credit (or any
amendment which increases the amount of such Letter of Credit) will be subject to the further conditions that such Letter of Credit shall be in such form and contain such terms as the Issuing Bank shall approve and that the Borrowers shall have
executed and delivered any Letter of Credit Agreement relating to such Letter of Credit as the Issuing Bank shall reasonably require; provided, that in the event of any conflict between such Letter of Credit Agreement and this Agreement, the terms
of this Agreement shall control. 
 (c) At least two Business Days prior to the issuance of any Letter of Credit, the Issuing Bank
will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received such notice and if not, the Issuing Bank will provide the Administrative Agent with a copy thereof. Unless the Issuing Bank has
received notice from the Administrative Agent on or before the Business Day immediately preceding the date the Issuing Bank is to issue the requested Letter of Credit (1) directing the Issuing Bank not to issue the Letter of Credit because such
issuance is not then permitted hereunder because of the limitations set forth in Section 2.6(a) or (2) that one or more of the conditions precedent set forth in Section 8 of this Agreement are not then satisfied, then, subject to the
terms and conditions hereof, the Issuing Bank shall, on the requested date, issue such Letter of Credit in accordance with the Issuing Bank’s usual and customary business practices. 
 (d) The Issuing Bank shall examine all documents purporting to represent a demand for payment under a Letter of Credit promptly following its
receipt thereof. The Issuing Bank shall notify the Company and the Administrative Agent of such demand for payment and whether the Issuing Bank has made or will make a LC Disbursement thereunder; provided, that any failure to give or delay in
giving such notice shall not relieve the Borrowers of their obligations to reimburse the Issuing Bank and the Revolving Credit Lenders with respect to such LC Disbursement. The Borrowers shall be irrevocably and unconditionally obligated to
reimburse the Issuing Bank for any LC Disbursements paid by the Issuing Bank in respect of such drawing upon the Issuing Bank’s written demand therefor, but otherwise without presentment, demand or other formalities of any kind. Unless the
Company shall have notified the Issuing Bank and the Administrative Agent prior to 11:00 a.m. on the Business Day immediately prior to the date on which drawing is honored that the Borrowers intend to reimburse the Issuing Bank for the amount of
such drawing in funds other than from the proceeds of Revolving Loans, the Borrowers shall be deemed to have timely given a Notice of 
  

 27 








 Borrowing to the Administrative Agent requesting the Revolving Credit Lenders to make a Base Rate Borrowing on the date
on which such drawing is honored in an exact amount due to the Issuing Bank. The Administrative Agent shall notify the Revolving Credit Lenders of such Borrowing in accordance with Section 2.3, and each Revolving Credit Lender shall make the
proceeds of its Base Rate Loan included in such Borrowing available to the Administrative Agent for the account of the Issuing Bank in accordance with Section 2.8. The proceeds of such Borrowing shall be applied directly by the Administrative
Agent to reimburse the Issuing Bank for such LC Disbursement. 
 (e) If for any reason a Base Rate Borrowing may not be (as determined
in the sole discretion of the Administrative Agent), or is not, made in accordance with the foregoing provisions, then each Revolving Credit Lender (other than the Issuing Bank) shall be obligated to fund the participation that such Revolving Credit
Lender purchased pursuant to subsection (a) in an amount equal to its Revolving Credit Percentage of such LC Disbursement on and as of the date which such Base Rate Borrowing should have occurred. Each Revolving Credit Lender’s obligation
to fund its participation shall be absolute and unconditional and shall not be affected by any circumstance, including without limitation (i) any setoff, counterclaim, recoupment, defense or other right that such Revolving Credit Lender or any
other Person may have against the Issuing Bank or any other Person for any reason whatsoever, (ii) the existence of a Default or an Event of Default or the termination of the Aggregate Revolving Commitments, (iii) any adverse change in the
condition (financial or otherwise) of the Borrowers or any of their Subsidiaries, (iv) any breach of this Agreement by any Borrower or any other Revolving Credit Lender, (v) any amendment, renewal or extension of any Letter of Credit or
(vi) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing provided, however, that the obligation of each Revolving Credit Lender to fund any such participation is subject to
the condition that the Issuing Bank believed in good faith that all conditions under Section 8.2 were satisfied at the time the Letter of Credit was issued. On the date that such participation is required to be funded, each Revolving Credit
Lender shall promptly transfer, in immediately available funds, the amount of its participation to the Administrative Agent for the account of the Issuing Bank. Whenever, at any time after the Issuing Bank has received from any such Revolving Credit
Lender the funds for its participation in a LC Disbursement, the Issuing Bank (or the Administrative Agent on its behalf) receives any payment on account thereof, the Administrative Agent or the Issuing Bank, as the case may be, will distribute to
such Revolving Credit Lender its Revolving Credit Percentage of such payment; provided, that if such payment is required to be returned for any reason to a Borrower or to a trustee, receiver, liquidator, custodian or similar official in any
bankruptcy proceeding, such Revolving Credit Lender will return to the Administrative Agent or the Issuing Bank any portion thereof previously distributed by the Administrative Agent or the Issuing Bank to it. 
 (f) To the extent that any Revolving Credit Lender shall fail to pay any amount required to be paid pursuant to paragraph (d) of this
Section 2.6 on the due date therefor, such Revolving Credit Lender shall pay interest to the Issuing Bank (through the Administrative Agent) on such amount from such due date to the date such payment is made at a rate per annum equal to the
Federal Funds Rate; provided, that if such Revolving Credit Lender shall fail to make such payment to the Issuing Bank within three (3) Business Days of such due date, then, retroactively to the due date, such Revolving Credit Lender
shall be obligated to pay interest on such amount at the rate for Default Interest. 
  

 28 








 (g) If any Event of Default shall occur and be continuing, on the Business Day that the Company
receives notice from the Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this paragraph, the Borrowers shall deposit in an account with the Administrative Agent, in the name of the Administrative
Agent and for the ratable benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided, that the obligation to deposit such cash collateral shall become effective
immediately, and such deposit shall become immediately due and payable, without demand or notice of any kind, upon the occurrence of any Event of Default with respect to the Borrowers described in Sections 9.1(g) or 9.1(h). Such deposit shall be
held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrowers under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal,
over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrowers’ risk and expense, such deposits shall not
bear interest. Interest and profits, if any, on such investments shall accumulate in such account. Moneys in such account shall applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it had not been
reimbursed and to the extent so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrowers for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, with the consent of the Required
Lenders, be applied to satisfy other obligations of the Borrowers under this Agreement. If the Borrowers are required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent
not so applied as aforesaid) shall be returned to the Borrowers one Business Day after all Events of Default have been cured or waived. 
 (h) Promptly following the end of each fiscal quarter, the Issuing Bank shall deliver (through the Administrative Agent) to each Lender and the Company a report describing the aggregate Letters of Credit outstanding at the end of
such fiscal quarter. Upon the request of any Lender from time to time, the Issuing Bank shall deliver to such Lender any other information reasonably requested by such Lender with respect to each Letter of Credit then outstanding. 
 (i) The Borrowers’ obligations to reimburse LC Disbursements hereunder shall be absolute, unconditional and irrevocable and shall be
performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever and irrespective of any of the following circumstances: 
 (1) Any lack of validity or enforceability of any Letter of Credit or this Agreement; 
 (2) The existence of any claim, set-off, defense or other right which a Borrower or any Subsidiary or Affiliate of a Borrower may have at
any time against a 
  

 29 








 beneficiary or any transferee of any Letter of Credit (or any Persons or entities for whom any such
beneficiary or transferee may be acting), any Lender (including the Issuing Bank) or any other Person, whether in connection with this Agreement or the Letter of Credit or any document related hereto or thereto or any unrelated transaction;

 (3) Any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any
respect or any statement therein being untrue or inaccurate in any respect; 
 (4) Payment by the Issuing Bank under a Letter
of Credit against presentation of a draft or other document to the Issuing Bank that does not comply with the terms of such Letter of Credit; 
 (5) Any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of
setoff against, the Borrowers’ obligations hereunder; or 
 (6) The existence of a Default or an Event of Default.

 (j) Neither the Administrative Agent, the Issuing Bank, the Lenders nor any Related Party of any of the foregoing shall have any
liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to above), or any error,
omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided, that neither the foregoing nor the provisions of 2.6(i) shall be construed to excuse the Issuing Bank from liability to the Borrowers to
the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrowers to the extent permitted by applicable law) suffered by the Borrowers that are caused by the Issuing Bank’s
failure to exercise care when determining whether drafts or other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree, that in the absence of gross negligence or willful misconduct on the
part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof,
the parties agree that, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such
documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such
Letter of Credit. 
 (k) Each Letter of Credit shall be subject to the International Standby Practices, International Chamber of
Commerce Publication No. 590 (1998), as the same may be amended from time to time, and, to the extent not inconsistent therewith, the governing law of this Agreement set forth in Section 11.5. 
  

 30 








 (l) Each Existing Letter of Credit shall be deemed to be a Letter of Credit issued by SunTrust
Bank as the Issuing Bank on the Closing Date. 
 2.7 Additional Revolving Loans. 
 (a) From time to time after the Closing Date, the Borrowers may, upon written notice to the Administrative Agent (who shall promptly provide a copy
of such notice to each Lender), request an increase (the “Increase Request”) in the Aggregate Revolving Commitment Amount (the amount of any such increase, the “Additional Revolving Commitment Amount”). The Increase
Request shall specify the amount of the Additional Revolving Commitment Amount and the date on which the Additional Revolving Commitment Amount is to become effective (the “Increase Date”) (which shall be a Business Day at least ten
Business Days after the delivery of the Increase Request and at least 30 days prior to the Commitment Termination Date). 
 (b) The
increase in the Aggregate Revolving Commitment Amount shall be conditioned upon satisfaction of the following conditions: 
 (1) after giving effect to such increase, the Aggregate Revolving Commitment Amount shall not exceed $90,000,000 (less any voluntary reductions pursuant to Section 2.20); 
 (2) no Default or Event of Default shall have occurred and be continuing on the relevant Increase Date or shall result from any Additional
Revolving Commitment Amount; 
 (3) the representations and warranties of the Borrowers set forth in this Agreement shall be
true and correct on and as of the relevant Increase Date as if made on and as of such date (or, if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date); and 
 (4) One or more existing or new Revolving Credit Lenders shall have agreed to acquire the Additional Revolving Commitment Amount.

 (c) Upon the receipt of the Increase Request, the Administrative Agent shall direct the Arranger to solicit the acquisition of the
Additional Revolving Commitment Amount by having existing Revolving Credit Lenders increase their respective Revolving Commitments then in effect, or by adding as new Revolving Credit Lenders with new Revolving Commitments hereunder Persons who are
not then Revolving Credit Lenders (each a “New Revolving Credit Lender”), with the approval of the Administrative Agent, which shall not be unreasonably withheld or delayed, and the Company. Each existing Revolving Credit Lender
shall have the right for a period of ten (10) Business Days following its receipt of the Increase Request to elect, by written notice to the Borrowers and the Administrative Agent, to acquire all or any part of the 
  

 31 








 Additional Revolving Commitment Amount, which notice shall specify the amount such existing Revolving Credit Lender
wishes to acquire (with each existing Revolving Credit Lender giving such notice being referred to herein as an “Increasing Revolving Credit Lender” and with such amount specified by such Increasing Revolving Credit Lender being
referred to herein as a “Proposed Increase Amount”). If the total of the Proposed Increase Amounts exceeds the Additional Revolving Commitment Amount requested by the Borrowers, then the Additional Revolving Commitment Amount shall
be allocated ratably among the Increasing Revolving Credit Lenders, with each Increasing Revolving Credit Lender’s allocation being a fraction, the numerator of which shall be the Proposed Increase Amount of such Increasing Revolving Credit
Lender and the denominator of which shall be the sum of all of the Proposed Increase Amounts. No existing Revolving Credit Lender (or any successor thereto) shall have any obligation to increase its Revolving Commitment or its other obligations
under this Agreement and the other Loan Documents, and any decision by an existing Revolving Credit Lender to increase its Revolving Commitment shall be made in its sole discretion independently from any other Revolving Credit Lender. New Revolving
Credit Lenders will be solicited only if the total Proposed Increase Amounts are less than the Additional Revolving Commitment Amount requested by the Borrowers. The Borrowers shall cooperate and actively assist the Administrative Agent and the
Arranger in connection with any such solicitation and shall reimburse the Administrative Agent and the Arranger for any reasonable out-of-pocket fees or expenses incurred in connection with such solicitation. 
 (d) An increase in the aggregate amount of the Aggregate Revolving Commitment Amount pursuant to this Section 2.7 shall become effective upon
the receipt by the Administrative Agent of an agreement in form and substance satisfactory to the Administrative Agent signed by the Borrowers, the other Loan Parties and each Increasing Revolving Credit Lender and each New Revolving Credit Lender,
setting forth the new or increased Revolving Commitments of such Revolving Credit Lenders, together with a replacement or additional Revolving Note, as applicable, evidencing the new or increased Revolving Commitment of each affected Revolving
Credit Lender, duly executed and delivered by the Borrowers and such evidence of appropriate corporate authorization on the part of the Borrowers and the other Loan Parties with respect to the increase in the Revolving Commitments and such opinions
of counsel for the Borrowers and the other Loan Parties with respect to the increase in the Aggregate Revolving Commitment Amount as the Administrative Agent may reasonably request. 
 (e) Upon the acceptance of any such agreement by the Administrative Agent, the Aggregate Revolving Commitment Amount shall automatically be
increased by the amount of the Revolving Commitments added through such agreement, and this Agreement shall automatically be deemed amended to reflect the Revolving Commitments of all Lenders after giving effect to the addition of such Revolving
Commitments. 
 (f) Upon any increase in the aggregate amount of the Revolving Commitments pursuant to this Section 2.7 that is
not pro rata among all Revolving Credit Lenders, within five (5) Business Days, the Borrowers shall concurrently prepay such Revolving Loans in their entirety and, to the extent the Borrowers elect to do so and subject to the conditions
specified in Section 8, the Borrowers shall reborrow Revolving Loans from the 
  

 32 








 Revolving Credit Lenders in proportion to their respective Revolving Commitments after giving effect to such increase,
until such time as all outstanding Revolving Loans are held by the Revolving Credit Lenders in such proportion. 
 2.8 Funding of
Borrowings. 
 (a) Each Lender will make available each Loan to be made by it hereunder on the proposed date thereof by wire
transfer in immediately available funds by 1:00 p.m. to the Administrative Agent at the Payment Office; provided that the Swingline Loans will be made as set forth in Section 2.5. The Administrative Agent will make such Loans available
to the Borrowers by promptly crediting the amounts that it receives, in like funds by 3:00 p.m. on such proposed date, to an account maintained by the Company with the Administrative Agent or at the Company’s option, by effecting a wire
transfer of such amounts to an account designated by the Company to the Administrative Agent. 
 (b) Unless the Administrative Agent
shall have been notified by any Lender prior to the date of a Borrowing in which such Lender is participating that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent
may assume that such Lender has made such amount available to the Administrative Agent on such date, and the Administrative Agent, in reliance on such assumption, may make available to the Borrowers on such date a corresponding amount. If such
corresponding amount is not in fact made available to the Administrative Agent by such Lender on the date of such Borrowing, the Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender together with
interest at the Federal Funds Rate for up to two (2) days and thereafter at the rate specified for such Borrowing. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the
Administrative Agent shall promptly notify the Company, and the Borrowers shall immediately pay such corresponding amount to the Administrative Agent together with interest at the rate specified for such Borrowing. Nothing in this subsection shall
be deemed to relieve any Lender from its obligation to fund its pro rata share of any Borrowing hereunder or to prejudice any rights which the Borrowers may have against any Lender as a result of any default by such Lender hereunder. 
 (c) No Lender shall be responsible for any default by any other Lender in its obligations hereunder, and each Lender shall be obligated to make
its Loans provided to be made by it hereunder, regardless of the failure of any other Lender to make its Loans hereunder. 
 2.9
Interest Elections. 
 (a) On the Closing Date, each Borrowing shall be an Index Rate Loan. After the Closing Date, each
Borrowing initially shall be of the Type specified in the applicable Notice of Borrowing, and in the case of a LIBOR Borrowing, shall have an initial Interest Period as specified in such Notice of Borrowing. Thereafter, the Borrowers may elect to
convert such Borrowing into a different Type or to continue such Borrowing, and in the case of a LIBOR Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrowers may elect different options with respect to
different portions of the affected Borrowing, in which 
  

 33 








 case each such portion shall be allocated ratably among the Lenders holding Loans comprising such Borrowing, and the
Loans comprising each such portion shall be considered a separate Borrowing. Notwithstanding the foregoing, at no time shall the total number of LIBOR Borrowings outstanding exceed six and the aggregate principal amount of each LIBOR Borrowing shall
be not less than $500,000 or a larger multiple of $100,000, and the aggregate principal amount of each Base Rate Borrowing and each Index Rate Borrowing shall not be less than $500,000 or a larger multiple of $100,000; provided, that Base
Rate Loans and Index Rate Loans made pursuant to Section 2.5 or Section 2.6(d) may be made in lesser amounts as provided therein. If a Notice of Borrowing does not specify a Type, the Borrowers shall be deemed to have requested an Index
Rate Borrowing. 
 (b) To make an election pursuant to this Section, the Company shall give the Administrative Agent prior written
notice (or telephonic notice promptly confirmed in writing) of each Borrowing (a “Notice of Conversion/Continuation”) that is to be converted or continued, as the case may be, (x) prior to 12:00 noon one (1) Business Day prior to
the requested date of a conversion into a Base Rate Borrowing or an Index Rate Borrowing and (y) prior to 12:00 noon three (3) Business Days prior to a continuation of or conversion into a LIBOR Borrowing. Each such Notice of
Conversion/Continuation shall be irrevocable and shall specify (i) the Borrowing to which such Notice of Continuation/Conversion applies and if different options are being elected with respect to different portions thereof, the portions thereof
that are to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) shall be specified for each resulting Borrowing); (ii) the effective date of the election made
pursuant to such Notice of Continuation/Conversion, which shall be a Business Day, (iii) whether the resulting Borrowing is to be a Base Rate Borrowing, an Index Rate Borrowing or a LIBOR Borrowing; and (iv) if the resulting Borrowing is
to be a LIBOR Borrowing, the Interest Period applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of “Interest Period.” If any such Notice of Continuation/Conversion requests a
LIBOR Borrowing but does not specify an Interest Period, the Borrowers shall be deemed to have selected an Interest Period of one month. 
 (c) If, on the expiration of any Interest Period in respect of any LIBOR Borrowing, the Company shall have failed to deliver a Notice of Conversion/Continuation when required by Section 2.9(b), then, unless such Borrowing is
repaid as provided herein, the Borrowers shall be deemed to have elected to convert such Borrowing to an Index Rate Borrowing. No Borrowing may be converted into, or continued as, a LIBOR Borrowing if a Default or an Event of Default exists, unless
the Administrative Agent and the Required Lenders shall have otherwise consented in writing. No conversion of any LIBOR Loans shall be permitted except on the last day of the Interest Period in respect thereof, except as required by
Section 2.16(ii). 
 (d) Upon receipt of any Notice of Conversion/Continuation, the Administrative Agent shall promptly notify
each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing. 
 2.10 Repayment of Loans.

 (a) The outstanding principal amount of all Revolving Loans shall be due and payable (together with accrued and unpaid interest
thereon) on the Commitment Termination Date. 
  

 34 








 (b) The principal amount of each Swingline Borrowing shall be due and payable on the Swingline
Termination Date. 
 2.11 Interest on Loans. The Borrowers shall pay interest on the unpaid principal amount of each Loan from
the date of such Loan until such principal amount shall be paid in full, at the following rates per annum: 
 (a) During such periods
as such Loan is an Index Rate Loan, at a rate per annum equal to the Index Rate plus the relevant Applicable Margin in effect from time to time. The interest rate on Index Rate Loans shall be established based on the Index Rate in effect on the
first Index Rate Determination Date, and shall be adjusted on each Index Rate Determination Date thereafter to reflect the Index Rate then in effect. 
 (b) During such periods as such Loan is a Base Rate Loan, a rate per annum equal at all times to the Base Rate plus the relevant Applicable Margin in effect from time to time. The rate at which interest accrues
on the unpaid principal balance of the Base Rate Loans shall be changed effective as of the date of any change in the Base Rate. 
 (c)
During such periods as such Loan is a LIBOR Loan, at a rate per annum equal to the LIBOR for the applicable Interest Period plus the relevant Applicable Margin in effect from time to time. The applicable LIBOR shall remain in effect until the
end of the applicable Interest Period. 
 (d) While an Event of Default exists or after acceleration, the Borrowers shall pay interest
(“Default Interest”) with respect to (i) all LIBOR Loans at the rate otherwise applicable for the then-current Interest Period plus an additional 2% per annum until the earlier of (x) the date such Event of Default is
cured or waived in accordance with the terms of this Agreement and (y) the last day of such Interest Period, and thereafter so long as such Event of Default is continuing or after acceleration, at the rate then in effect for Base Rate Loans,
plus an additional 2% per annum, and (ii) with respect to all other Obligations hereunder, at the rate then in effect for Base Rate Loans, plus an additional 2% per annum. 
 (e) Interest on the principal amount of all Loans shall accrue from and including the date such Loans are made to but excluding the date of any
repayment thereof. Interest on all outstanding Base Rate Loans and Index Rate Loans shall be payable monthly in arrears on the last day of each calendar month and on the Commitment Termination Date or the Swingline Termination Date, as the case may
be. Interest on all outstanding LIBOR Loans shall be payable on the last day of each Interest Period applicable thereto, and, in the case of any LIBOR Loans having an Interest Period in excess of three months, on each day which occurs every three
months, after the initial date of such Interest Period, and on the Commitment Termination Date. Interest on any Loan which is converted into a Loan of another Type or which is repaid or prepaid shall be payable on the date of such conversion or on
the date of any such repayment or prepayment (on the amount repaid or prepaid) thereof. All Default Interest shall be payable on demand. 
  

 35 








 (f) The Administrative Agent shall determine each interest rate applicable to the Loans hereunder
and shall promptly notify the Company and the Lenders of such rate in writing (or by telephone, promptly confirmed in writing). Any such determination shall be conclusive and binding for all purposes, absent manifest error. 
 2.12 Fees. 
 (a) The
Borrowers shall pay to the Administrative Agent and the Arranger, for their own respective accounts, fees in the amounts and at the times previously agreed upon in writing by the Borrowers and the Administrative Agent and the Arranger. 

(b) The Borrowers agree to pay to the Administrative Agent for the account of each Revolving Credit Lender the applicable Unused Fee, which
shall accrue from the date of this Agreement at the percentage applicable from time to time based on the Senior Funded Debt Ratio of the Company and its Subsidiaries on the daily amount of the unused Revolving Commitment of such Lender until the
Commitment Termination Date. Accrued Unused Fees shall be payable in arrears on the last day of each March, June, September and December of each year and on the Commitment Termination Date, commencing on the first such date after the date of this
Agreement. For purposes of computing unused fees with respect to the Revolving Commitments, the Revolving Commitment of each Lender shall be deemed used to the extent of the outstanding Revolving Loans and LC Exposure of such Lender. 
 (c) The Borrowers agree to pay (i) to the Administrative Agent, for the account of each Revolving Credit Lender, a letter of credit fee with
respect to its participation in each Letter of Credit, which shall accrue at the Applicable Margin then applicable to Revolving LIBOR Loans, on the average daily amount of such Revolving Credit Lender’s LC Exposure (excluding any portion
thereof attributable to unreimbursed LC Disbursements) attributable to such Letter of Credit during the period from and including the date of issuance of such Letter of Credit to but excluding the date on which such Letter of Credit expires or is
drawn in full (including without limitation any LC Exposure that remains outstanding after the Commitment Termination Date) and (ii) to the Issuing Bank for its own account a fronting fee, which shall accrue at the rate of 0.25% per annum
on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) attributable to such Letter of Credit during the period from and including the date of issuance of such Letter of Credit to
but excluding the date on which such Letter of Credit expires or is drawn in full (including without limitation any LC Exposure that remains outstanding after the Commitment Termination Date), as well as the Issuing Bank’s standard fees with
respect to issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Accrued letter of credit and fronting fees shall be payable quarterly in arrears on the last day of each March, June, September and
December, commencing on March 31, 2006, and on the Commitment Termination Date (and if later, the date the LC Exposure shall be repaid in its entirety). 
  

 36 








 2.13 Computation of Interest and Fees. Interest with respect to Base Rate Loans shall be
calculated on basis of a year of 365 or 366 days, as applicable, for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable. All other computations of interest
and fees hereunder shall be made on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable (to the extent computed
on the basis of days elapsed). Each determination by the Administrative Agent of an interest amount or fee hereunder shall be made in good faith and, except for manifest error, shall be final, conclusive and binding for all purposes. 
 2.14 Evidence of Indebtedness. 
 (a) Each Lender shall maintain in accordance with its usual practice appropriate records evidencing the indebtedness of the Borrowers to such Lender resulting from each Loan made by such Lender from time to time, including the
amounts of principal and interest payable thereon and paid to such Lender from time to time under this Agreement. The Administrative Agent shall maintain appropriate records in which shall be recorded (i) the Revolving Commitment of each
Lender, (ii) the amount of each Loan made hereunder by each Lender, the Class and Type thereof and the Interest Period applicable thereto, (iii) the date of each continuation thereof pursuant to Section 2.9, (iv) the date of each
conversion of all or a portion thereof to another Type pursuant to Section 2.9, (v) the date and amount of any principal or interest due and payable or to become due and payable from the Borrowers to each Lender hereunder in respect of
such Loans and (vi) both the date and amount of any sum received by the Administrative Agent hereunder from the Borrowers in respect of the Loans and each Lender’s pro rata share thereof. The entries made in such records shall be prima
facie evidence of the existence and amounts of the obligations of the Borrowers therein recorded; provided, that the failure or delay of any Lender or the Administrative Agent in maintaining or making entries into any such record or any
error therein shall not in any manner affect the obligations of the Borrowers to repay the Loans (both principal and unpaid accrued interest) of such Lender in accordance with the terms of this Agreement. 
 (b) At the request of any Lender (including the Swingline Lender) at any time, each Borrower agrees that it shall execute and deliver to such
Lender a Revolving Note and, in the case of the Swingline Lender only, a Swingline Note, payable to the order of such Lender, in the applicable amount of such Lender’s Commitment. 
 2.15 Inability to Determine Interest Rates. If prior to the commencement of any Interest Period for any LIBOR Borrowing or on the Index
Rate Determination Date for any Index Rate Borrowing, 
 (1) the Administrative Agent shall have determined (which
determination shall be conclusive and binding upon the Borrowers) that, by reason of circumstances affecting the relevant interbank market, adequate means do not exist for ascertaining LIBOR for such Interest Period or the Index Rate on such
Index Rate Determination Date, or 
  

 37 








 (2) the Administrative Agent shall have received notice from any Lender that the
applicable LIBOR or the Index Rate, as applicable, does not adequately and fairly reflect the cost to such Lender of making, funding or maintaining its, as the LIBOR Loans for such Interest Period or its Index Rate Loans, as applicable, 

the Administrative Agent shall give written notice (or telephonic notice, promptly confirmed in writing) to the Company and to the Lenders as soon as practicable
thereafter. In the case of LIBOR Loans, until the Administrative Agent shall notify the Company and the Lenders that the circumstances giving rise to such notice no longer exist, (i) the obligations of the Lenders to make LIBOR Loans or Index
Rate Loans or to continue or convert outstanding Loans as or into LIBOR Loans or Index Rate Loans shall be suspended and (ii) all such affected LIBOR Rate Loans shall be converted into Base Rate Loans on the last day of the then current
Interest Period applicable thereto, and all Index Rate Loans shall automatically be converted to Base Rate Loans, unless, in either case, the Borrowers prepay such Loans in accordance with this Agreement. Unless the Company notifies the
Administrative Agent at least one Business Day before the date of any LIBOR Revolving Loan Borrowing for which a Notice of Borrowing as to such Revolving Loan Borrowing has previously been given that the Borrowers elect not to borrow on such date,
then such Revolving Loan Borrowing shall be made as a Base Rate Borrowing. 
 2.16 Illegality. If any Change in Law shall make
it unlawful or impossible for any Lender to make, maintain or fund any LIBOR Loan or Index Rate Loan and such Lender shall so notify the Administrative Agent, the Administrative Agent shall promptly give notice thereof to the Company and the other
Lenders, whereupon until such Lender notifies the Administrative Agent and the Company that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make LIBOR Loans and Index Rate Loans, or to continue or
convert outstanding Loans as or into LIBOR Loans or Index Rate Loans, shall be suspended. In the case of the making of a LIBOR Revolving Loan Borrowing or Index Rate Revolving Loan Borrowing, such Lender’s Revolving Loan shall be made as a Base
Rate Loan as part of the same Revolving Loan Borrowing and if the affected LIBOR Loan or Index Rate Loan is then outstanding, such Loan shall be converted to a Base Rate Loan either (i) on the last day of the then current Interest Period
applicable to such LIBOR Loan if such Lender may lawfully continue to maintain such Loan to such date or (ii) immediately if such Lender shall determine that it may not lawfully continue to maintain such LIBOR Loan to such date, and immediately
in the case of an Index Rate Loan. Notwithstanding the foregoing, the affected Lender shall, prior to giving such notice to the Administrative Agent, designate a different Applicable Lending Office if such designation would avoid the need for giving
such notice and if such designation would not otherwise be disadvantageous to such Lender in the good faith exercise of its discretion. 
  

 38 








 2.17 Increased Costs. 
 (a) If any Change in Law shall: 
 (1) impose, modify or deem applicable any reserve, special deposit or similar requirement that is not otherwise included in the determination of LIBOR or the Index Rate hereunder against assets of, deposits with or
for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Index Rate or LIBOR) or the Issuing Bank; or 
 (2) impose on any Lender or on the Issuing Bank or the eurodollar interbank market any other condition affecting this Agreement or any Index Rate Loans or LIBOR Loans made by such Lender or any Letter of Credit or any
participation therein; 
 and the result of the foregoing is to increase the cost to such Lender of making, converting into, continuing or maintaining an
Index Rate Loan or a LIBOR Loan or to increase the cost to such Lender or the Issuing Bank of participating in or issuing any Letter of Credit or to reduce the amount received or receivable by such Lender or the Issuing Bank hereunder (whether of
principal, interest or any other amount), then the Borrowers shall promptly pay, upon written notice from and demand by such Lender on the Company (with a copy of such notice and demand to the Administrative Agent), to the Administrative Agent for
the account of such Lender, within five Business Days after the date of such notice and demand, the additional amount or amounts sufficient to compensate such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or
reduction suffered. 
 (b) If any Lender or the Issuing Bank shall have determined that on or after the date of this Agreement any
Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital (or on the capital of such Lender’s or the Issuing Bank’s parent company) as
a consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s parent company could have achieved but for such
Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies or the policies of such Lender’s or the Issuing Bank’s parent company with respect to capital adequacy) then, from time to time, within five
(5) Business Days after receipt by the Company of written demand by such Lender (with a copy thereof to the Administrative Agent), the Borrowers shall pay to such Lender such additional amounts as will compensate such Lender or the Issuing Bank
or such Lender’s or the Issuing Bank’s parent company for any such reduction suffered. Notwithstanding the foregoing, the affected Lender shall, prior to giving such notice to the Administrative Agent, designate a different Applicable
Lending Office if such designation would avoid the need for giving demand hereunder and if such designation would not otherwise be disadvantageous to such Lender in the good faith exercise of its discretion. 
 (c) A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or
such Lender’s or the Issuing Bank’s parent company, as the case may be, specified in paragraph (a) or (b) of this Section, and the calculation thereof, shall be delivered to the Company (with a copy to the Administrative Agent)
and shall be conclusive, absent manifest error. The Borrowers shall pay any such Lender or the Issuing Bank, as the case may be, such amount or amounts within 10 days after receipt thereof. 
  

 39 








 2.18 Funding Indemnity. In the event of (a) the payment of any principal of a LIBOR
Loan other than on the last day of the Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion or continuation of a LIBOR Loan other than on the last day of the Interest Period applicable thereto,
or (c) the failure by the Borrowers to borrow, prepay, convert or continue any LIBOR Loan on the date specified in any applicable notice (regardless of whether such notice is withdrawn or revoked), then, in any such event, the Borrowers shall
compensate each Lender, within five (5) Business Days after written demand from such Lender, for any loss, cost or expense attributable to such event. In the case of a LIBOR Loan, such loss, cost or expense shall be deemed to include an amount
determined by such Lender to be the excess, if any, of (A) the amount of interest that would have accrued on the principal amount of such LIBOR Loan if such event had not occurred at LIBOR applicable to such LIBOR Loan 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 for such LIBOR Loan) over (B) the amount of
interest that would accrue on the principal amount of such LIBOR Loan for the same period if LIBOR were set on the date such LIBOR Loan was prepaid or converted or the date on which the Borrowers failed to borrow, convert or continue such LIBOR
Loan. A certificate as to any additional amount payable under this Section submitted to a Borrower by any Lender (with a copy to the Administrative Agent) shall be conclusive, absent manifest error. 
 2.19 Taxes. 
 (a) Any
and all payments by or on account of any obligation of the Borrowers hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided, that if the Borrowers shall be required to deduct any
Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the
Administrative Agent, any Lender or the Issuing Bank (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrowers shall make such deductions and (iii) the
Borrowers shall pay the full amount deducted to the relevant governmental authority in accordance with applicable law. 
 (b) In
addition, the Borrowers shall pay any Other Taxes to the relevant governmental authority in accordance with applicable law. 
 (c) The
Borrowers shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within five (5) Business Days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent,
such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrowers hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts
payable under this Section) and any penalties, 
  

 40 








 interest and reasonable expenses arising therefrom or with respect thereto (other than penalties, interest and expenses
arising from gross negligence, willful misconduct or a material breach of the material obligations of the Administrative Agent, such Lender or the Issuing Bank, as the case may be, which breach continues after notice thereof has been given to such
party in breach by the Borrowers), whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant governmental authority. A certificate as to the amount of such payment or liability delivered to
the Borrowers by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error. 
 (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrowers to a governmental authority, the Borrowers shall
deliver to the Administrative Agent the original or a certified copy of a receipt issued by such governmental authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to
the Administrative Agent. 
 (e) Any Foreign Lender that becomes a party to this Agreement and that is entitled to an exemption from
or reduction of withholding tax under the Code or any treaty to which the United States is a party with respect to payments under this Agreement shall deliver to the Borrowers (with a copy to the Administrative Agent), at the time or times
prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrowers as will permit such payments to be made without withholding or at a reduced rate. Without limiting
the generality of the foregoing, each Foreign Lender agrees that it will deliver to the Administrative Agent and the Borrowers (or in the case of a Participant, to the Lender from which the related participation shall have been purchased), as
appropriate, two (2) duly completed copies of (i) Internal Revenue Service Form W-8 ECI, or any successor form thereto, certifying that the payments received from the Borrowers hereunder are effectively connected with such Foreign
Lender’s conduct of a trade or business in the United States; or (ii) Internal Revenue Service Form W-8 BEN, or any successor form thereto, certifying that such Foreign Lender is entitled to benefits under an income tax treaty to which the
United States is a party which reduces the rate of withholding tax on payments of interest; or (iii) Internal Revenue Service Form W-8 BEN, or any successor form prescribed by the Internal Revenue Service, together with a certificate
(A) establishing that the payment to the Foreign Lender qualifies as “portfolio interest” exempt from U.S. withholding tax under Code section 871(h) or 881(c), and (B) stating that (1) the Foreign Lender is not a bank for
purposes of Code section 881(c)(3)(A), or the obligation of a Borrower hereunder is not, with respect to such Foreign Lender, a loan agreement entered into in the ordinary course of its trade or business, within the meaning of that section;
(2) the Foreign Lender is not a 10% shareholder of a Borrower within the meaning of Code section 871(h)(3) or 881(c)(3)(B); and (3) the Foreign Lender is not a controlled foreign corporation that is related to a Borrower within the meaning
of Code section 881(c)(3)(C); or (iv) such other Internal Revenue Service forms as may be applicable to the Foreign Lender, including Forms W-8 IMY or W-8 EXP. Each such Foreign Lender shall deliver to the Borrowers and the Administrative Agent
such forms on or before the date that it becomes a party to this Agreement (or in the case of a Participant, on or before the date such Participant purchases the related participation). In addition, each such Foreign Lender 
  

 41 








 shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Foreign
Lender. Each such Foreign Lender shall promptly notify the Borrowers and the Administrative Agent at any time that it determines that it is no longer in a position to provide any previously delivered certificate to the Borrowers (or any other form
of certification adopted by the Internal Revenue Service for such purpose). Each Foreign Lender agrees to indemnify and hold the Borrowers harmless from any United States taxes, penalties, interest and other expenses, losses or costs incurred or
payable as a result of the Borrowers’ reliance on the forms and certificates delivered by such Foreign Lender pursuant to this Section 2.19(e). For any period for which a Foreign Lender has failed to provide the forms and certifications
contemplated by this Section 2.19(e), such Foreign Lender shall not be entitled to indemnification under Section 2.19 for any Indemnified Taxes imposed by the United States which would not have been imposed but for the failure of such
Foreign Lender to provide such forms. 
 2.20 Optional Reduction and Termination of Commitments. 
 (a) Unless previously terminated, all Revolving Commitments shall terminate on the Commitment Termination Date, except that the Swingline
Commitment shall terminate on the Swingline Termination Date. 
 (b) Upon at least three (3) Business Days’ prior written
notice (or telephonic notice promptly confirmed in writing) from the Company to the Administrative Agent (which notice shall be irrevocable), the Borrowers may reduce the Aggregate Revolving Commitments in part or terminate the Aggregate Revolving
Commitments in whole, provided, that (i) any partial reduction shall apply to reduce proportionately and permanently the Revolving Commitment of each Revolving Credit Lender, (ii) any partial reduction pursuant to this
Section 2.20 shall be in an amount of at least $5,000,000 and any larger multiple of $1,000,000, and (iii) no such reduction shall be permitted which would reduce the Aggregate Revolving Commitments to an amount less than the outstanding
Revolving Credit Exposures of all Revolving Credit Lenders. Any such reduction in the Aggregate Revolving Commitments shall result in a proportionate reduction (rounded to the next lowest integral multiple of $100,000) in the Swingline Commitment
and the LC Commitment. 
 2.21 Optional Prepayments. The Borrowers shall have the right at any time and from time to time to
prepay any Borrowing, in whole or in part, by giving irrevocable written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent no later than (i) in the case of prepayment of any LIBOR Borrowing, 12:00 noon not
less than three (3) Business Days prior to any such prepayment, (ii) in the case of any prepayment of any Base Rate Borrowing or Index Rate Borrowing, not less than one Business Day prior to the date of such prepayment, and (iii) in
the case of Swingline Borrowings, prior to 12:00 noon on the date of such prepayment, provided that no notice shall be required for the prepayment of any Cash Management Swingline Loans. Each such notice shall be irrevocable and shall specify the
proposed date of such prepayment and the principal amount of each Borrowing or portion thereof to be prepaid. Upon receipt of any such notice, the Administrative Agent shall promptly notify each affected Lender of the contents thereof and of such
Lender’s pro rata share of any such 
  

 42 








 prepayment. If such notice is given, the aggregate amount specified in such notice shall be due and payable on the date
designated in such notice, together with accrued interest to such date on the amount so prepaid in accordance with Section 2.11; provided, that if a LIBOR Borrowing is prepaid on a date other than the last day of an Interest Period
applicable thereto, the Borrowers shall also pay all amounts required pursuant to Section 2.18. Each partial prepayment of any Loan (other than a Swingline Loan) shall be in an amount that would be permitted in the case of an advance of a
Revolving Loan Borrowing of the same Type pursuant to Section 2.2 or in the case of a Swingline Loan pursuant to Section 2.4. Each prepayment of a Borrowing shall be applied ratably to the Loans comprising such Borrowing. 
 2.22 Mandatory Prepayments and Commitment Reductions. 
 (a) Upon the occurrence of any Equity Issuance by the Company or any of its Subsidiaries, the Borrowers shall prepay the Revolving Loans in an amount equal to the lesser of (x) the then outstanding
principal amount of the Revolving Loans and accrued and unpaid interest thereon and (y) 100% of the Net Cash Proceeds of such Equity Issuance. Such prepayment shall be made within ten (10) Business Days after the date of such Equity
Issuance and shall be applied toward the prepayment of the Revolving Loans as set forth in Section 2.22(d). 
 (b) Upon the
incurrence of any Debt (as specified in clauses (a) and (j) of the definition thereof) by the Company or any of its Subsidiaries (excluding any Obligations), the Borrowers shall prepay the Revolving Loans in an amount equal to the lesser
of (x) the then outstanding principal amount of the Revolving Loans and accrued and unpaid interest thereon and (y) 100% of the Net Cash Proceeds of such Debt. Such prepayment shall be applied within ten (10) Business Days
after the date of such incurrence of Debt toward the prepayment of the Revolving Loans as set forth in Section 2.22(d). 
 (c) If
on any date the Company or any of its Subsidiaries shall receive Net Cash Proceeds from any Asset Sale, Purchase Price Refund or Recovery Event then, unless a Reinvestment Notice shall be delivered in respect thereof (within ten (10) Business
Days after such Asset Sale, Purchase Price Refund or Recovery Event), the Borrowers shall prepay the Revolving Loans in an amount equal to the lesser of (x) the then outstanding principal amount of the Revolving Loans and accrued and unpaid
interest thereon and (y) such Net Cash Proceeds. Such prepayment shall be applied on the 11th Business Day
following such Asset Sale, Purchase Price Refund or Recovery Event toward the prepayment of the Revolving Loans as set forth in Section 2.22(d). 
 (d) Amounts to be applied in connection with prepayments made pursuant to this Section 2.22 shall be applied to the prepayment of the Revolving Loans, but not the reduction of the Revolving Commitments.
The application of any prepayment pursuant to this Section 2.22 shall be made, first, to Base Rate Loans, second, to Index Rate Loans and, third, to LIBOR Loans; provided that if such prepayment of LIBOR Loans would
result in a breakage cost pursuant to Section 2.18(a), the Company shall have the option to direct the Administrative Agent to invest the prepayment otherwise required to be made on such LIBOR Loans in 
  

 43 








 certificates of deposit or money market accounts issued by the bank serving as the Administrative Agent (but otherwise at
the Company’s sole risk) until the end of the currently effective interest periods for such LIBOR Loans or such time as such LIBOR Loans may otherwise be prepaid without a breakage cost pursuant to Section 2.18(a); such investments shall
be deemed to be additional collateral for the Obligations and held on the terms of Section 3 hereof. Each prepayment of the Loans under this Section shall be accompanied by accrued interest to the date of such prepayment on the amount prepaid.

 (e) If at any time the Revolving Credit Exposure of all Lenders exceeds the Aggregate Revolving Commitment Amount, as reduced
pursuant to Section 2.21 or otherwise, the Borrowers shall immediately repay Swingline Loans and Revolving Loans in an amount equal to such excess, together with all accrued and unpaid interest on such excess amount and any amounts due under
Section 2.18. Each prepayment shall be applied first to the Swingline Loans to the full extent thereof, second to the Base Rate Loans to the full extent thereof, third to the Index Rate Loans to the fullest extent thereof, and finally to the
LIBOR Loans to the full extent thereof. If after giving effect to prepayment of all Loans, the Revolving Credit Exposure of all Lenders exceeds the Aggregate Revolving Commitment Amount, the Borrowers shall be required to provide cash collateral for
the Letters of Credit pursuant to the foregoing sentence, the Borrowers shall effect the same by paying to the Administrative Agent, for the benefit of the Issuing Bank, immediately available funds in an amount equal to the required amount, which
funds shall be retained by the Administrative Agent, for the benefit of the Issuing Bank, in a cash collateral account until the earlier to occur of (1) the date the affected Letters of Credit shall have been terminated or cancelled, and
(2) the date the Revolving Credit Exposure of all Lenders no longer exceeds the Aggregate Revolving Commitment Amount, at which time the cash collateral shall be paid to the Company. 
 2.23 Payments Generally; Pro Rata Treatment; Sharing of Set-offs. 
 (a) Each borrowing by the Borrowers from the Lenders hereunder, each payment by the Borrowers on account of any Unused Fee or Letter of Credit Fee
(other than the fronting fee payable solely to the Issuing Bank) and any reduction of the Revolving Commitments of the Lenders shall be made pro rata according to the respective Revolving Credit Percentages of the relevant Lenders.
Each payment (other than prepayments) in respect of principal or interest in respect of the Loans and each payment in respect of fees payable hereunder shall be applied to the amounts of such obligations owing to the Lenders pro rata
according to the respective amounts then due and owing to the Lenders. 
 (b) Each payment (including each prepayment) by the
Borrowers on account of principal of and interest on the Revolving Credit Loans shall be made pro rata according to the respective outstanding principal amounts of the Revolving Credit Loans then held by the Revolving Credit Lenders.
Each payment in respect of LC Disbursements in respect of any Letter of Credit shall be made to the Issuing Bank that issued such Letters of Credit. 
 (c) The Borrowers shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of 
  

 44 








 amounts payable under Sections 2.17, 2.18 or 2.19, or otherwise) prior to 12:00 noon, on the date when due, in
immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of
calculating interest thereon. All such payments shall be made to the Administrative Agent at the Payment Office, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments
pursuant to Sections 2.17, 2.18 and 2.19 and 11.3 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient
promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest
thereon shall be made payable for the period of such extension. All payments hereunder shall be made in Dollars. 
 (d) If at any time
insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of
interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then
due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties. 
 (e) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements or
Swingline Loans that would result in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and Swingline Loans and accrued interest thereon than the proportion received by
any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements and Swingline Loans; provided,
that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest,
and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrowers pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans or participations in LC Disbursements or Swingline Loans to any assignee or participant, other than to the Borrowers or any Subsidiary or Affiliate thereof (as to which the provisions of
this paragraph shall apply). Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the
Borrowers rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of a Borrower in the amount of such participation. 
  

 45 








 (f) Unless the Administrative Agent shall have received notice from the Company prior to the date
on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrowers will not make such payment, the Administrative Agent may assume that the Borrowers have made such payment on such
date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount or amounts due. In such event, if the Borrowers have not in fact made such payment, then each of the
Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with generally accepted banking industry rules on
interbank compensation then in effect. 
 (g) If any Lender shall fail to make any payment required to be made by it pursuant to
Sections 2.5(b), 2.6(c) or 2.6(d), 2.6(e), 2.23(d) or 11.3(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of
such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. 
 2.24
Mitigation of Obligations; Replacement of Lenders. 
 (a) Determination of amounts payable under Sections 2.16, 2.17, 2.18
or 2.19 in connection with a LIBOR Borrowing shall be calculated as though each Lender funded its LIBOR Borrowing through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the LIBOR
applicable to such LIBOR Borrowing, whether in fact that is the case or not. If any Lender is unable to make or maintain LIBOR Loans when other Lenders are able to make or maintain LIBOR Loans, requests compensation under Section 2.17, or if
the Borrowers are required to pay any additional amount to any Lender or any governmental authority for the account of any Lender pursuant to Section 2.19, then, upon the Company’s written request to such Lender, such Lender shall use
reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the sole judgment of such Lender, such
designation or assignment (i) would eliminate or reduce amounts payable under Section 2.17 or Section 2.19, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would
not otherwise be disadvantageous to such Lender. The Borrowers hereby agree to pay all reasonable costs and expenses incurred by any Lender in connection with such designation or assignment requested by the Company. 
 (b) If any Lender is unable to make or maintain LIBOR Loans when other Lenders are able to make or maintain LIBOR Loans, requests compensation
under Section 2.17, or if a Borrower is required to pay any additional amount to any Lender or any governmental 
  

 46 








 authority for the account of any Lender pursuant to Section 2.19, or if any Lender defaults in its obligation to
fund Loans hereunder, then the Borrowers may, at their sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions
set forth in Section 11.4(b), and the Borrowers shall be obligated to pay the recordation and processing fee referred to therein) all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations
(which assignee may be another Lender); provided, that (i) the Borrowers shall have received the prior written consent of the Administrative Agent, which consent shall not be unreasonably withheld, (ii) such Lender shall have
received payment of an amount equal to the outstanding principal amount of all Loans owed to it, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (in the case of such outstanding principal and
accrued interest) and from the Borrowers (in the case of all other amounts), (iii) the Borrowers shall be liable to such replaced Lender under Section 2.18 (as though Section 2.18 were applicable) if any LIBOR Loan owing to such
replaced Lender shall be purchased other than on the last day of the Interest Period relating thereto, and (iv) no Event of Default shall have occurred and be continuing. A Lender shall not be required to make any such assignment and delegation
if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply. 
 (c) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to Sections 2.17, 2.18 or 2.19 shall not
constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation, provided that the Borrowers shall not be required to compensate a Lender or the Issuing Bank pursuant to Sections 2.17, 2.18 or 2.19 for any
increased costs incurred or reductions suffered more than 180 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Company of the Change in Law or other event giving rise to such tax, increased costs or
reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor (except that, if the Change in Law or other event giving rise to such tax, increased costs or reductions is retroactive, then the 180-day period
referred to above shall be extended to include the period of retroactive effect thereof). 
 SECTION 3. Security. 
 3.1 Security Interest. Each Borrower hereby assigns and pledges to the Administrative Agent, for the ratable benefit of the Lenders, and
hereby grants to the Administrative Agent, for the ratable benefit of the Lenders, a first priority security interest in all of such Borrower’s right, title and interest in and to the Collateral (subject to Liens permitted by this Agreement),
whether now owned or hereafter acquired by such Borrower, including all proceeds of any and all of the foregoing or hereinafter-described Collateral (including, without limitation, proceeds that constitute property of the types described herein)
and, to the extent not otherwise included, all policies of insurance on any property of such Borrower and all payments and proceeds under any such insurance (whether or not the Administrative Agent is the loss payee thereof, for the ratable benefit
of the Lenders), or any indemnity warranty or guaranty payable by reason of loss or damage to or otherwise with respect to any of the foregoing 
  

 47 








 Collateral; all cash proceeds of the Collateral; and all books of account and records, including all computer software
relating thereto. This Agreement secures the payment of all Obligations of the Borrowers now or hereafter existing or arising. Without limiting the generality of the foregoing, this Agreement secures the payment of all amounts that constitute part
of the Obligations and would be owed by each Borrower to the Administrative Agent and any of the Lenders but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding
involving such Borrower. 
 3.2 Representations and Warranties Concerning the Collateral. 
 (a) All items of equipment and inventory of each Borrower with an aggregate book value in excess of $100,000 are located at the places specified in
Schedule 3.2 hereto. During the five years immediately preceding the date of this Agreement, no Borrower nor any predecessor of any Borrower has used any corporate or fictitious name other than its current corporate name. No Borrower has
any trade names. The chief executive office and mailing address of each Borrower is located at 11730 Plaza America Drive, Reston, Virginia 20190. The exact legal name of each Borrower is that indicated on the signature pages hereof. The Borrowers
are organizations of the types, and are organized in the jurisdictions, set forth herein. The signature page hereof accurately sets forth each Borrower’s organizational identification number. 
 (b) The Borrowers are the legal and beneficial owners of the Collateral free and clear of any lien, security interest, option or other charge or
encumbrance except for the security interest created by this Agreement or permitted by this Agreement. No effective financing statement or other document similar in effect covering all or any part of the Collateral is on file in any recording
office, except those filed in connection with the Existing Agreement as permitted by this Agreement such as may have been filed in favor of the Administrative Agent, for the ratable benefit of the Lenders, relating to this Agreement or otherwise
permitted by this Agreement. 
 (c) The Borrowers have exclusive possession and control of the Collateral. 
 (d) This Agreement creates a valid security interest in the Collateral, securing the payment of the Obligations and, when properly perfected,
shall constitute a valid perfected security interest in such Collateral, free and clear of all Liens except as created or permitted by this Agreement. 
 (e) Any inventory produced by a Borrower has been produced by such Borrower in compliance with all requirements of the Fair Labor Standards Act. 
 (f) Each Borrower represents and warrants as to each and every Receivable included in assets on the consolidated balance sheet of the Company and
its Subsidiaries that: (1) it is a bona fide existing obligation, valid and enforceable to the knowledge of the Company against the Customer, for software installed or licensed, goods sold or leased or services rendered in the ordinary
course of business; (2) it is subject to no dispute, defense or offset in an amount of greater than $500,000 except as disclosed in writing to the Administrative Agent or as 
  

 48 








 reflected or reserved for in the financial statements delivered from time to time by the Borrowers to the Administrative
Agent hereunder; (3) all instruments, chattel paper and other evidence of indebtedness issued to a Borrower with respect to any Receivable have been made available to the Administrative Agent, and, together with all supporting documents
delivered to the Administrative Agent, are genuine, complete, valid and enforceable in accordance with their terms; (4) it is not subject to any material discount, allowance or special terms of payment except in the ordinary course of business
or as disclosed in writing to the Administrative Agent; and (5) except as required by the Assignment of Claims Act, it is not and shall not be subject to any prohibition or limitation upon assignment. 
 (g) As of the Closing Date, no Borrower owns in fee any real property, other than the Condo Unit, or any leasehold estate in any real property
with a term (including all renewal options) of more than 20 years. 
 3.3 Covenants Concerning the Collateral. 
 (a) Each Borrower shall promptly inform the Administrative Agent of (1) any dispute in excess of $500,000 with a Customer and (2) the
bankruptcy, insolvency, receivership, assignment for the benefit of creditors or suspension of business of any material Customer of which such Borrower has knowledge. No Borrower shall compromise or discount any Receivable without the prior written
consent of the Administrative Agent except for ordinary trade discounts or allowances for prompt payment or as otherwise deemed by such Borrower to be in its best commercial interests. 
 (b) Upon the occurrence and during the continuation of an Event of Default, upon demand by the Administrative Agent, each Borrower shall establish
and maintain a lockbox with the Administrative Agent and shall direct all Customers to make payments on Collateral to such lockbox by printing such direction on all invoices given to Customers. Each Borrower also shall remit to such lockbox or
deliver to the Administrative Agent all payments on Collateral received by such Borrower. Such payments shall be remitted or delivered in their original form on the day of receipt. All notes, checks and other instruments so received by each Borrower
shall be duly endorsed to the order of the Administrative Agent. The payments remitted to the lockbox and all payments delivered to the Administrative Agent shall be credited to a cash collateral account maintained by the Administrative Agent in the
name of the Company over which the Administrative Agent shall have the exclusive power of withdrawal. All collected funds in such cash collateral account shall be applied to the Obligations by the Administrative Agent on each Business Day, whether
or not the Obligations are then due. 
 (c) Upon the occurrence and during the continuation of an Event of Default, to facilitate
direct collection of the Collateral, the Administrative Agent shall have the right to take over the post office boxes of the Borrowers or make other arrangements, with which the Borrowers shall cooperate, to receive the mail of each Borrower.

 (d) The Borrowers shall execute all other agreements, instruments and documents and shall perform all further acts that the
Administrative Agent may require with respect to Receivables owing by the Government to ensure compliance with the Assignment of 
  

 49 








 Claims Act, provided that, as long as no Event of Default has occurred and is continuing, the Administrative Agent has no
present intent to require, but reserves the right to so require, Assignment of Claims Act filings for any Government Contract. 
 (e)
All of the inventory and equipment of each Borrower will be kept only at the locations set forth on Schedule 3.2, as amended from time to time upon written notice from the Company to the Administrative Agent The Borrowers shall give the
Administrative Agent prior written notice before any material inventory or equipment is moved or delivered to a location other than such designated places of business, and the lien and security interest of the Administrative Agent for the ratable
benefit of the Lenders will be maintained despite the location of the inventory or equipment. Without the prior written consent of the Administrative Agent, no Borrower shall move or deliver inventory or equipment with a book value in any instance
or in the aggregate of $200,000 or more to a location outside of the United States of America. The foregoing provisions shall not apply to inventory sold in the ordinary course of business of the Borrowers. 
 (f) Each Borrower shall have its equipment and inventory insured against loss or damage by fire, theft, burglary, pilferage, loss in
transportation and such other hazards as the Administrative Agent shall reasonably specify, by insurers reasonably satisfactory to the Administrative Agent, in amounts reasonably satisfactory to the Administrative Agent and under policies containing
loss payable clauses satisfactory to the Administrative Agent. Any such insurance policies, or certificates or other evidence thereof satisfactory to the Administrative Agent, shall be deposited with the Administrative Agent. Each Borrower agrees
that the Administrative Agent, for the ratable benefit of the Lenders, shall have a security interest in such policies and the proceeds of such policies thereof, and if any loss shall occur during the continuation of an Event of Default, the
proceeds relating to the loss or damage of the equipment or inventory may be applied to the payment of the Obligations or to the replacement or restoration of the inventory or equipment damaged or destroyed, as the Administrative Agent may elect or
direct. After the occurrence and during the continuance of an Event of Default, the Administrative Agent shall have the right to file claims under any insurance policies, to receive, receipt and given acquittance for any payments that may be made
thereunder, and to execute any and all endorsements, receipts, releases, assignments, reassignments or other documents that may be necessary to effect to the collection, compromise, or settlement of any claims under any of the insurance policies.

 (g) Each Borrower, at its expense, will defend the Collateral against any claims or demands adverse to the Administrative
Agent’s security interest and will promptly pay when due all taxes or assessments levied against such Borrower on the Collateral, except for Liens created or permitted by this Agreement, or as contested by such Borrower in good faith and in
appropriate proceedings, provided that the enforcement of any such claim or demand is stayed during the term of such contest and proceedings. 
 (h) Each Borrower shall provide the Administrative Agent such information as the Administrative Agent from time to time reasonably may request with respect to the Collateral, including, without limitation, statements describing,
designating, identifying and evaluating all Collateral. 
  

 50 








 3.4 Perfection of Security Interest. 
 (a) Each Borrower hereby irrevocably authorizes the Administrative Agent, for the ratable benefit of the Lenders, at any time and from time to time
to file in any Uniform Commercial Code jurisdiction any initial financing statements and amendments thereto that (1) indicate the Collateral (i) as all assets of such Borrower or words of similar effect, regardless of whether any
particular asset comprised in the Collateral falls within the scope of Article 9A of the Uniform Commercial Code of the State or such jurisdiction, or (ii) as being of an equal or lesser scope or with greater detail, and (2) contain any
other information required by part 5 of Article 9A of the Uniform Commercial Code of the State or such jurisdiction for the sufficiency or filing office acceptance of any financing statement or amendment, including (i) whether such Borrower is
an organization, the type of organization and any organization identification number issued to such Borrower and, (ii) 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 Borrower agrees to furnish any such information to the Administrative Agent promptly upon request. Each Borrower also ratifies its authorization for the
Administrative Agent to have filed in any Uniform Commercial Code jurisdiction any like initial financing statements or amendments thereto if filed prior to the date hereof. 
 (b) Without providing at least 10 days’ prior written notice to the Administrative Agent, no Borrower shall change its name, its type of
organization, jurisdiction of organization or other legal structure, its place of business or, if more than one, chief executive office, or its mailing address or organizational identification number if it has one. If a Borrower does not have an
organizational identification number and later obtains one, such Borrower shall forthwith notify the Administrative Agent of such organizational identification number. 
 (c) If a Borrower shall at any time hold or acquire any promissory notes or tangible chattel paper as part of the Collateral, such Borrower shall forthwith endorse, assign and deliver the same to the
Administrative Agent, for the ratable benefit of the Lenders, accompanied by such instruments of transfer or assignment duly executed in blank as the Administrative Agent may from time to time specify. 
 (d) For each deposit account that a Borrower at any time opens or maintains, such Borrower shall, at the Administrative Agent’s request,
pursuant to a control agreement in form and substance satisfactory to the Administrative Agent, cause the depositary bank to agree to comply at any time during the continuation of an Event of Default with instructions from the Administrative Agent
to such depositary bank directing the disposition of funds from time to time credited to such deposit account, without further consent of such Borrower. The Administrative Agent agrees with each Borrower that the Administrative Agent shall not give
any such instructions or withhold any withdrawal rights from such Borrower, unless an Event of Default has occurred and is continuing or would occur as a result thereof. The provisions of this paragraph shall not apply to (i) any deposit
account for which a Borrower, the depositary bank 
  

 51 








 and the Administrative Agent have entered into a cash collateral agreement specially negotiated among such Borrower, the
depositary bank and the Administrative Agent for the specific purpose set forth therein, (ii) deposit accounts for which the Administrative Agent is the depositary, (iii) deposit accounts specially and exclusively used for payroll, payroll
taxes and other employee wage and benefit payments to or for the benefit of such Borrower’s salaried employees, and (iv) deposit accounts for which such Borrower is acting as an agent to distribute funds other than funds of the Borrower to
a third party. 
 (e) If a Borrower shall at any time hold or acquire any certificated securities, such Borrower shall, upon the
Administrative Agent’s written request therefor, forthwith endorse, assign and deliver the same to the Administrative Agent to be held as Collateral for the ratable benefit of the Lenders, accompanied by such instruments of transfer or
assignment duly executed in blank as the Administrative Agent may from time to time specify. If any securities now or hereafter acquired by a Borrower are uncertificated and are issued to such Borrower or its nominee directly by the issuer thereof,
that Borrower shall immediately notify the Administrative Agent thereof and, at the Administrative Agent’s request and option, pursuant to an agreement in form and substance satisfactory to the Administrative Agent, cause the issuer to agree to
comply during the continuation of an Event of Default with instructions from the Administrative Agent as to such securities, without further consent of such Borrower or such nominee. If any securities, whether certificated or uncertificated, or
other investment property now or hereafter acquired by a Borrower are held by such Borrower or its nominee through a securities intermediary or commodity intermediary, such Borrower shall immediately notify the Administrative Agent thereof and, at
the Administrative Agent’s request, pursuant to a securities control agreement in form and substance satisfactory to the Administrative Agent, cause such securities intermediary or (as the case may be) commodity intermediary to agree to comply
during the continuation of an Event of Default with entitlement orders or other instructions from the Administrative Agent to such securities intermediary as to such securities or other investment property, or (as the case may be) to apply any value
distributed on account of any commodity contract as directed by the Administrative Agent to such commodity intermediary, in each case without further consent of such Borrower or such nominee. The Administrative Agent agrees with each Borrower that
the Administrative Agent shall not give any such entitlement orders or instructions or directions to any such issuer, securities intermediary or commodity intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing
rights by such Borrower, unless an Event of Default has occurred and is continuing, or, after giving effect to any such investment and withdrawal rights not otherwise permitted by the Loan Documents, would occur. The provisions of this paragraph
shall not apply to any financial assets credited to a securities account for which the Administrative Agent is the securities intermediary. 
 (f) If any goods with an aggregate book value in excess of $250,000 are at any time in the possession of a bailee, each Borrower shall promptly notify the Administrative Agent thereof and, if requested by the Administrative Agent,
shall promptly obtain an acknowledgement from the bailee, in form and substance satisfactory to the Administrative Agent, that the bailee holds such Collateral for the benefit of the Administrative Agent and shall act upon the instructions of the
Administrative Agent, without the further consent of such Borrower. The Administrative Agent agrees with each Borrower that the Administrative Agent 
  

 52 








 shall not give any such instructions unless an Event of Default has occurred and is continuing or would occur after
taking into account any action by such Borrower with respect to the bailee. 
 (g) If a Borrower at any time holds or acquires an
interest in any electronic chattel paper or any “transferable record,” as that term is defined in Section 201 of the federal Electronic Signatures in Global and National Commerce Act, or in §16 of the Uniform Electronic
Transactions Act as in effect in any relevant jurisdiction, such Borrower shall promptly notify the Administrative Agent thereof and, at the request of the Administrative Agent, shall take such action as the Administrative Agent may reasonably
request to vest in the Administrative Agent, for the ratable benefit of the Lenders, control, under §9-105 of the Uniform Commercial Code, of such electronic chattel paper or control under Section 201 of the Federal Electronic Signatures
in Global and National Commerce Act or, as the case may be, §16 of the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such transferable record. The Administrative Agent agrees with each Borrower that the
Administrative Agent will arrange, pursuant to procedures satisfactory to the Administrative Agent and so long as such procedures will not result in the Administrative Agent’s loss of control, for such Borrower to make alterations to the
electronic chattel paper or transferable record permitted under UCC §9-105 or, as the case may be, Section 201 of the federal Electronic Signatures in Global and National Commerce Act or §16 of the Uniform Electronic Transactions Act
for a party in control to make without loss of control, unless an Event of Default has occurred and is continuing or would occur after taking into account any action by such Borrower with respect to such electronic chattel paper or transferable
record. 
 (h) If a Borrower is at any time a beneficiary under a letter of credit now or hereafter issued in favor of such Borrower,
that Borrower shall promptly notify the Administrative Agent thereof and, at the request of the Administrative Agent, such Borrower shall, pursuant to an agreement in form and substance satisfactory to the Administrative Agent, arrange for the
issuer and any confirmer of such letter of credit to consent to an assignment to the Administrative Agent, for the ratable benefit of the Lenders, during the continuation of an Event of Default of the proceeds of any drawing under the letter of
credit, with the Administrative Agent agreeing that the proceeds of any drawing under the letter to credit are to be applied to the payment of the Obligations, for the ratable benefit of the Lenders. 
 (i) If a Borrower shall at any time hold or acquire a commercial tort claim in excess of $100,000, that Borrower shall promptly notify the
Administrative Agent in a writing signed by such Borrower of the brief details thereof and grant to the Administrative Agent, for the ratable benefit of the Lenders, in such writing a security interest therein and in the proceeds thereof, all upon
the terms of this Agreement, with such writing to be in form and substance satisfactory to the Administrative Agent. 
 (j) If
required by the Administrative Agent, each Borrower that owns any Intellectual Property that is registered with the United States Patent and Trademark Office or the United States Copyright Office, shall execute and deliver an Intellectual Property
Assignment and shall record such Intellectual Property Assignment with the United States Patent and Trademark Office and the United States Copyright Office, as applicable. 
  

 53 








 (k) Each Borrower further agrees to take any other action reasonably requested by the
Administrative Agent to insure the attachment, perfection and first priority of, and the ability of the Administrative Agent to enforce, the Administrative Agent’s security interest in any and all of the Collateral, for the ratable benefit of
the Lenders, including, without limitation, (1) executing, delivering and, where appropriate, filing financing statements and amendments relating thereto under the Uniform Commercial Code, to the extent, if any, that such Borrower’s
signature thereon is required therefor, (2) causing the Administrative Agent’s name to be noted as the Lender on any certificate of title for a titled good if such notation is a condition to attachment, perfection or priority of, or
ability of the Administrative Agent to enforce, the Administrative Agent’s security interest in such Collateral, held for the ratable benefit of the Lenders, (3) complying with any provision of any statute, regulation or treaty of the
United States as to any Collateral if compliance with such provision is a condition to attachment, perfection or priority of, or ability of the Administrative Agent to enforce, the Administrative Agent’s security interest in such Collateral,
held for the ratable benefit of the Lenders, (4) obtaining governmental and other third party consents and approvals, including without limitation any consent of any licensor, lessor or other person obligated on Collateral, (5) obtaining
waivers from mortgagees and landlords in form and substance satisfactory to the Administrative Agent and (6) taking all actions required by any earlier versions of the Uniform Commercial Code or by other law, as applicable in any relevant
Uniform Commercial Code jurisdiction, or by other law as applicable in any foreign jurisdiction. 
 3.5 Power of Attorney. Each
Borrower appoints the Administrative Agent and any officer, employee or agent of the Administrative Agent, as the Administrative Agent from time to time may designate, as attorneys-in-fact for a Borrower to perform all actions necessary or desirable
in the discretion of the Administrative Agent to enforce its security interest in the Collateral, for the ratable benefit of the Lenders, and to exercise such rights and powers as each Borrower might exercise with respect to the Collateral, all at
the reasonable cost and expense of the Borrowers. Each Borrower agrees that neither the Administrative Agent nor any other such attorney-in-fact will be liable for any acts of omission or commission, nor for any error of judgment or mistake of law
or fact, unless such acts constitute willful misconduct, gross negligence or a material breach of the material obligations of the Administrative Agent under this Agreement which breach continues after notice thereof has been given by the Borrowers.
This power is coupled with an interest and is irrevocable so long as any Obligations are outstanding. The Administrative Agent agrees that it shall be entitled to exercise its rights under this Section 3.5 only upon the occurrence and during
the continuation of an Event of Default. 
 3.6 Limitations on Obligations. It is expressly agreed by each Borrower that,
notwithstanding any other provision of this Agreement, each Borrower shall remain liable under each Receivable and contract giving rise to each Receivable to observe and perform all the conditions and obligations to be observed and performed by each
Borrower in accordance with and pursuant to the terms and provisions of each such Receivable and contract. Neither the Administrative Agent nor any Lender shall have any obligation or liability under any Receivable or contract by reason of or
arising out of this Agreement or the assignment of such Receivable or contract to the Administrative Agent, for the ratable benefit of the Lenders, or the receipt by the Administrative Agent, for the ratable benefit of the Lenders, of any payment
relating to the 
  

 54 








 Receivable pursuant to this Agreement, nor shall the Administrative Agent or any Lender be required or obligated in any
manner to perform or fulfill any of the obligations of a Borrower under or pursuant to any Receivable or contract, or to make any payment, or to make any inquiry as to the nature or the sufficiency of any payment received by it or the sufficiency of
any performance by any party under any Receivable, or to present or file any claim, or to take any action to collect or enforce any performance or the payment of any amounts that may have been assigned to it or to which it may be entitled at any
time or times. 
 SECTION 4. Representations and Warranties. Each Borrower represents and warrants to the Administrative Agent and each Lender
that: 
 4.1 Incorporation, Good Standing and Due Qualification. Each Borrower (a) is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its incorporation or formation; (b) has the power and authority to own its assets and to transact the business in which it is now engaged or in which it is proposed to be
engaged; and (c) is duly qualified as a foreign corporation or limited liability corporation and in good standing under the laws of each other jurisdiction in which such qualification is required, except when the failure to be so qualified
would not have a Material Adverse Effect. As of the date of this Agreement, the Company has no Subsidiaries other than NCI Virginia and SES, and neither NCI Virginia nor SES has any Subsidiaries. 
 4.2 Power and Authority. The execution, delivery and performance by the Borrowers of the Loan Documents have been duly authorized by all
necessary corporate actions and do not and will not (a) require any consent or approval of, or filing or registration with, any governmental agency or authority or the stockholders of a Borrower, other than the filing of financing statements as
required by the UCC, filings required by the Assignment of Claims Act and other filings contemplated by any of the Loan Documents relating to the creation or perfection of a Lien on any of the Collateral; (b) contravene a Borrower’s
articles or certificate of incorporation, articles or certificate of organization, or bylaws or operating agreement, as applicable; (c) result in a breach of or constitute a default under any material agreement or instrument to which a Borrower
is a party or by which it or its material properties may be bound or affected; (d) result in or require the creation or imposition of any Lien upon or with respect to any of the properties now owned or hereafter acquired by a Borrower, except
in favor of the Administrative Agent, for the ratable benefit of the Lenders; or (e) cause a Borrower to be in default under any material law, rule, regulation, order, writ, judgment, injunction, decree, determination or award applicable to the
Borrower, except, in the cases of clauses (a), (c) and (e), compliance with, and filings and notices under, the Assignment of Claims Act and other filings contemplated by any of the Loan Documents relating to the creation or perfection of a
Lien on any of the Collateral. 
 4.3 Legally Enforceable Agreement. This Agreement is, and each of the other Loan Documents
when delivered under this Agreement will be, legal, valid and binding obligations of each Borrower, enforceable against each Borrower in accordance with their respective terms, subject to bankruptcy, insolvency, reorganization or similar laws
relating to creditors’ rights generally and general principles of equity. 
  

 55 








 4.4 Financial Statements. The Company has furnished to the Administrative Agent and each
Lender (a) the audited balance sheet of the Company as of December 31, 2004, and the related statements of income, stockholders’ equity and cash flows for the fiscal year then ended prepared by Ernst & Young and (b) the
unaudited balance sheet of the Company as of December 31, 2005, and the related unaudited statement of income for the fiscal quarter and year-to-date period then ending, certified by a Principal Officer. Such financial statements are complete
and fairly present in all material respects the financial condition of the Company as of the dates of such statements. Since the dates of such statements, there has been no material adverse change in the business, assets, liabilities (actual or
contingent), operations or financial condition of the Borrowers. 
 4.5 Litigation; Environmental Matters. 
 (a) There is no pending or threatened action, investigation or proceeding against or affecting a Borrower before any court, governmental agency or
arbitrator, that, in any one case or in the aggregate, could reasonably be expected to have a Material Adverse Effect. 
 (b) No
Borrower (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law, (ii) has, to its knowledge, become subject to any Environmental
Liability, (iii) has received written notice of any claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability that, in any one case or in the aggregate, could reasonably be expected to

 4.6 Ownership and Liens. Each Borrower has title to all of its assets, including the
Collateral, and none of the Collateral or such assets is subject to any Lien, except Liens created or permitted by this Agreement or the other Loan Documents. 
 4.7 ERISA. No Borrower has incurred any material “accumulated funding deficiency” within the meaning of § 302 of ERISA or § 412 of the Code, nor has any Borrower
incurred any material liability to the PBGC in connection with any “employee pension benefit plan” (as defined in § 3(2) of ERISA) established or maintained by a Borrower. None of the employee pension benefit plans (as
defined above) or “welfare plans” (as defined in § 3(l) of ERISA) of a Borrower, nor any trusts created thereunder, nor any trustee or administrator thereof, has engaged in a “prohibited transaction,” as
such term is defined in § 406 of ERISA or § 4975 of the Code, that could subject a Borrower to any material liability or tax or penalty on prohibited transactions imposed by such §§ 406 or 4975. None of the
Borrowers nor any ERISA Affiliate of any Borrower is now, or at any time in the past three (3) years has been, obligated to make contributions to a “multiemployer plan,” as such term is defined in § 4001(a)(3) of
ERISA, with respect to which the withdrawal of any Borrower or any such ERISA Affiliate at any time could reasonably be expected to have a Material Adverse Effect. The only such multiemployer plans to which any Borrower is obligated to make
contributions are those described on Schedule 4.7. 
 4.8 Taxes. Each Borrower has filed all tax returns (federal, state
and local) required to be filed and has paid all taxes, assessments and governmental charges and levies shown 
  

 56 








 thereon to be due, including interest and penalties, except for such taxes being contested in good faith and as for which
reserves are being maintained in accordance with GAAP. 
 4.9 Use of Proceeds and Letters of Credit. The Borrowers will
use the proceeds of the Revolving Loans to finance working capital needs, Capital Expenditures, Permitted Acquisitions and for other general corporate purposes. No part of the proceeds of any Loan nor any Letter of Credit will be used, whether
directly or indirectly, for any purpose that would violate any rule or regulation of the Board of Governors of the Federal Reserve System, including Regulations T, U or X. All Letters of Credit will be used for general corporate purposes.

 4.10 Debt. No Borrower is in any manner directly or contingently obligated with respect to any Debt that is not permitted by
this Agreement. No Borrower is in default with respect to any Debt. 
 4.11 Debarment and Suspension. No event has occurred
and, to the knowledge of the Borrowers, no condition exists that may result in the debarment or suspension of a Borrower from any contracting with the Government, and no Borrower nor any Affiliate of a Borrower has been subject to any such debarment
or suspension prior to the date of this Agreement. No Government investigation or inquiry involving fraud, deception or willful misconduct has been commenced in connection with any Government Contract of a Borrower or a Subsidiary or any activities
of any Borrower or any Subsidiary. 
 4.12 Material Contracts. No Borrower, Subsidiary or, to the knowledge of the Borrowers,
any other party thereto is in material default under any Material Contract that would have a Material Adverse Effect. 
 4.13
Intellectual Property. As of the date hereof, the Borrowers and the Subsidiaries do not own or hold any registered copyrights, patents or trademarks, other than as listed on Schedule 4.13 attached hereto and other than such
Intellectual Property that has not been used by the Borrowers in the past 12 months or from which no revenue in excess of $100,000 has been derived in the past 12 months. Each Borrower and each Subsidiary owns or has the right to use under valid
license agreements or otherwise all Intellectual Property that is required or necessary for the conduct of the business of each Borrower and its Subsidiaries as now conducted to the knowledge of the Borrowers without any conflict with any rights of
any other Person that would have a Material Adverse Effect. 
 4.14 True and Complete Information. All factual information
(taken as a whole) previously furnished to the Administrative Agent or any Lender in connection with this Agreement by the Borrowers and each Subsidiary is, and all factual (taken as a whole) furnished to the Administrative Agent or any Lender by
the Borrowers and the Subsidiaries after the date of this Agreement will be, true and accurate in all material respects on the date on which such information is dated, certified or furnished, and is not, and will not be, incomplete by omitting to
state any material fact necessary to make such information (taken as a whole) not misleading in any material respect at such time in light of the circumstances under which such information was provided. 
  

 57 








 4.15 Integrated Business. The Borrowers and the Subsidiaries at all times will be, engaged
as an integrated group in providing services and goods to their respective Customers. The integrated operation will require financing on such a basis that credit supplied to the Borrowers be made available from time to time to all Borrowers and
Subsidiaries of the Borrowers, as required for the successful operation of the Borrowers and the Subsidiaries separately, and the integrated operation as a whole. In that connection, the Borrowers and the Subsidiaries will request that the Lenders
provide the Loans to, and that the Issuing Bank issue the Letters of Credit for, the Borrowers to finance such operation. Each Borrower will derive benefit, directly and indirectly, from the credit so extended to the Borrowers, both in its separate
capacity and as a member of the integrated group. 
 4.16 Employee Relations. Except for the agreement(s) set forth on
Schedule 4.16, no Borrower is a party to any collective bargaining agreement nor has any labor union been recognized as the representative of its employees. No Borrower knows of any pending, threatened or contemplated strikes, work stoppage
or other collective labor disputes involving its employees. 
 4.17 Burdensome Provisions. No Borrower is a party to any
indenture, agreement, lease or other instrument, or subject to any corporate or partnership restriction, governmental approval or applicable law which is so unusual or burdensome as in the foreseeable future could be reasonably expected to have a
Material Adverse Effect. No Borrower presently anticipates that future expenditures needed to meet the provisions of any statutes, orders, rules or regulations of a governmental authority will be so burdensome as to have a Material Adverse Effect.

 4.18 Absence of Defaults. No event has occurred and is continuing which constitutes a Default or an Event of Default. No
event has occurred and is continuing which constitutes, or which with the passage of time or giving of notice or both would constitute, a material default or event of default by any Borrower under contract or judgment, decree or order to which any
Borrower is a party or by which any Borrower or any of its material properties may be bound or which would require any Borrower to make any payment thereunder prior to the scheduled maturity date therefor, which could reasonably be expected to have
a Material Adverse Effect. 
 4.19 Disclosure. The Borrowers have disclosed to the Administrative Agent and each
Lender all agreements, instruments, and corporate or other restrictions to which the Borrowers or any of their respective Subsidiaries is subject, and all other matters known to any of them, that, individually or in the aggregate, could reasonably
be expected to result in a Material Adverse Effect. None of the reports (including without limitation all reports that the Company may be required to file with the Securities and Exchange Commission), certificates or other factual information
furnished by or on behalf of the Borrowers to the Administrative Agent or any Lender in connection with the negotiation or syndication of this Agreement or any other Loan Document or delivered hereunder or thereunder (as modified or supplemented by
any other information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, taken as a whole, in light of the circumstances under which they were made, not misleading.

  

 58 








 4.20 Survival of Representations and Warranties, Etc. All statements contained in any
certificate, or other instrument delivered by or on behalf of any Borrower to the Administrative Agent or any Lender pursuant to or in connection with this Agreement or any of the other Loan Documents (including, but not limited to, any such
statement made in or in connection with any amendment thereto or any statement contained in any certificate or other instrument delivered by or on behalf of any Borrower prior to the date hereof and delivered to the Administrative Agent or any
Lender in connection with closing the transactions contemplated hereby) shall constitute representations and warranties made by the Borrowers under this Agreement. All representations and warranties made under this Agreement and the other Loan
Documents shall be deemed to be made at and as of the date hereof, the Closing Date and at and as of the date of the disbursement of any Loan or issuance of any Letter of Credit, except to the extent that such representations and warranties
expressly relate solely to an earlier date (in which case such representations and warranties shall have been true and accurate on and as of such earlier date). All such representations and warranties shall survive the effectiveness of this
Agreement, the execution and delivery of the Loan Documents, the making of the Loans and the issuance of the Letters of Credit. 
 SECTION 5.
Affirmative Covenants. The Borrowers covenant and agree that so long as any Lender has a Commitment hereunder or the principal of or interest on any Loan remains unpaid or any fee or any LC Disbursement remains unreimbursed or any Letter
of Credit remains outstanding: 
 5.1 Maintenance of Existence. Each Borrower will preserve and maintain its corporate existence
and good standing in the jurisdiction of its formation, and qualify and remain qualified, as a foreign corporation in each jurisdiction in which such qualification is required. 
 5.2 Maintenance of Records. Each Borrower will keep adequate records and books of account, in which complete entries will be made in
accordance with GAAP, reflecting all financial transactions of such Borrower. The principal records and books of account, including those concerning the Collateral, shall be kept at the chief executive office of the Borrowers described above. No
Borrower will move such records and books of account or change its chief executive office or the name under which it does business without (a) giving the Administrative Agent at least 30 days’ prior written notice, and (b) filing, or
authorizing the filing by the Administrative Agent of, financing statements reasonably satisfactory to the Administrative Agent prior to such move or change. 
 5.3 Maintenance of Properties. Each Borrower will maintain, keep and preserve all of its properties (tangible and intangible) necessary or useful in the proper conduct of its business in good working
order and condition, ordinary wear and tear and casualty excepted, in all material respects. 
 5.4 Conduct of Business. Each
Borrower will continue to engage in a business of substantially the same general type as conducted by it on the date of this Agreement. 
 5.5 Maintenance of Insurance. Each Borrower will maintain insurance with financially sound and reputable insurance companies or associations in such amounts and 
  

 59 








 covering such risks as are usually carried by companies engaged in the same or a similar business and similarly situated,
including, without limitation, insurance covering the inventory and equipment as required hereby. 
 5.6 Compliance with Laws.
Each Borrower will comply in all respects with all applicable laws, rules, regulations and orders (including, without limitation, ERISA and all Environmental Laws) with respect to which non-compliance, in any one case or in the aggregate, could
reasonably be expected to have a Material Adverse Effect, such compliance to include, without limitation, paying, before the same become delinquent, all taxes, assessments and governmental charges imposed upon it or upon its property;
provided that the Borrowers shall have the right to contest the applicability or enforcement of any taxes, assessments and governmental charges imposed upon it or upon its property subject to the maintenance of reserves required by GAAP in
respect of any such contest. 
 5.7 Right of Inspection. At any reasonable time and from time to time, with reasonable notice,
each Borrower will permit, except as prohibited by applicable law, the Administrative Agent or any agent or representative of the Administrative Agent to audit, examine and verify the Collateral, examine and make copies of and abstracts from the
records and books of account of, and visit the properties of, each Borrower, and to discuss the affairs, finances and accounts of each Borrower with any of its officers and directors and each Borrower’s independent accountants (the Borrowers
having the right to notice of any meeting with their independent accountants and to have a representative of the Borrowers present at any such meeting), and to discuss the status of Government Contracts of each Borrower with the applicable
contracting officers of the Borrower. The Administrative Agent agrees to give the Borrowers not fewer than two days’ prior written notice of taking any action described in the preceding sentence, and to obtain the Borrowers’ permission
prior to contacting the contracting officer under any Government Contract, provided that if an Event of Default has occurred and is continuing, the Administrative Agent shall not be required to give such prior notice or obtain such permission. The
Borrowers agree to reimburse the Administrative Agent for all reasonable audit and Collateral verification and examination expenses incurred by it with respect to each audit and Collateral verification of each Borrower conducted by the
Administrative Agent, provided that such reimbursements shall not be required more frequently than once per calendar year unless an Event of Default has occurred and is continuing or is uncovered by such audit and Collateral verification, in which
case all of the reasonable expenses of each audit and verification shall be paid by the Borrowers. If the Administrative Agent uses employees or Affiliates to perform the audits, the Borrowers’ reimbursement obligations shall be limited to the
reasonable out-of-pocket expenses of the Administrative Agent that would have been paid to an independent auditing firm for such audits. 
 5.8 Reporting Requirements. The Borrowers will furnish to the Administrative Agent, at each address for the Administrative Agent specified in Section 11.1(a) (and the Administrative Agent will promptly after receipt

Lenders, in any way permitted by applicable law and shall have, without limitation, the remedies of a secured party under the UCC. The Administrative Agent may enter the premises of any Borrower without legal process and without incurring liability
to any Borrower and remove the Collateral to such place or places as the Administrative Agent may deem advisable, or the Administrative Agent may require the Borrowers to assemble the Collateral and make the Collateral available to the
Administrative Agent at a convenient place and, with or without having the Collateral at the time or place of sale, the Administrative Agent may, for the ratable benefit of the Lenders, sell or otherwise dispose of all or any part of the Collateral
whether in its then condition or after further preparation or processing, either at public or private sale or at any broker’s board, in lots or in bulk, for cash or for credit, at any time or place, in one or more sales and upon such terms and
conditions as the Administrative Agent may elect. The Administrative Agent shall give not less than ten Business Days’ prior written notice to the Borrowers of the time and place of any public sale of the Collateral or the time after which the
Collateral may be sold in a private sale, which each Borrower agrees constitutes commercially reasonable notice. At any such sale the Administrative Agent or any Lender may be the purchaser, subject to the applicable provisions of the UCC.

  

 74 








 (c) The Borrowers shall, at the request of the Administrative Agent, notify account debtors and
other persons obligated on any of the Collateral of the security interest of the Administrative Agent (held for the ratable benefit of the Lenders) in any account, chattel paper, general intangible, instrument or other Collateral and that payment
thereof is to be made directly to the Administrative Agent or to any financial institution designated by the Administrative Agent as the Administrative Agent’s agent therefor, and the Administrative Agent may itself, without notice to or demand
upon such Borrower, so notify account debtors and other persons obligated on Collateral. After the making of such a request or the giving of any such notification, such Borrower shall hold any proceeds of collection of accounts, chattel paper,
general intangibles, instruments and other Collateral received by such Borrower as trustee for the Administrative Agent without commingling the same with other funds of such Borrower and shall turn the same over to the Administrative Agent in the
identical form received, together with any necessary endorsements or assignments. The Administrative Agent shall apply the proceeds of collection of accounts, chattel paper, general intangibles, instruments and other Collateral received by the
Administrative Agent to the Obligations, ratably in favor of the Lenders, such proceeds to be immediately entered after final payment in cash or other immediately available funds of the items giving rise to them. 
 (d) Notwithstanding any other provisions of this Agreement to the contrary, after the occurrence of an Event of Default and the declaration of the
Obligations to be immediately due and payable in accordance with the provisions of this Agreement, all amounts collected or received by the Administrative Agent or any Lender on account of the Obligations or any other amounts outstanding under any
of the Loan Documents or in respect of the Collateral shall be paid over or delivered as follows: 
 (1) FIRST, to the payment
of all reasonable out-of-pocket costs and expenses (including without limitation reasonable attorneys’ fees) of the Administrative Agent in connection with enforcing the rights of the Lenders under the Loan Documents and any advances made by
the Administrative Agent with respect to the Collateral pursuant to Section 9.2(h); 
 (2) SECOND, to the payment of all
reasonable out-of-pocket costs and expenses of each of the Lenders in connection with enforcing its respective rights under the Loan Documents or otherwise with respect to the Obligations owing to such Lender and the reasonable fees of appraisers,
investment bankers or other professionals retained by the Administrative Agent to provide services to sell, collect or otherwise dispose of the Collateral; 
 (3) THIRD, to the payment of accrued fees and interest on the Swingline Loans; 
 (4) FOURTH,
to the payment of all of the other Obligations consisting of accrued fees and interest, and including with respect to any Hedging Agreement between any Borrower and any Lender, or any Affiliate of a Lender, any fees, premiums and scheduled periodic
payments due under such Hedging Agreement and any interest accrued thereon; 
  

 75 








 (5) FIFTH, to the payment of the outstanding principal amount of the Swingline Loans;

 (6) SIXTH, to the payment of the outstanding principal amount of the other Obligations and the payment or cash
collateralization of the outstanding LC Exposure and including with respect to any Hedging Agreement between any Borrower and any Lender, or any Affiliate of a Lender, any breakage, termination or other payments due under such Hedging Agreement and
any interest accrued thereon; 
 (7) SEVENTH, to all other Obligations and other obligations which shall have become due and
payable under the Loan Documents or otherwise and not repaid pursuant to clauses “FIRST” through “SIXTH” above; and 
 (8) EIGHTH, to the payment of the surplus, if any, to whomever may be lawfully entitled to receive such surplus. 
 In carrying out the foregoing, (i) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category; (ii) each of the Lenders shall receive an amount equal to
its pro rata share (based on the proportion that the then outstanding Aggregate Exposure and obligations outstanding under the Hedging Agreements (if any) held by such Lender (and its Affiliates in the case of Hedging Agreement obligations) bears to
the aggregate then outstanding Aggregate Exposure and obligations outstanding under the Hedging Agreements between any Borrower and any Lender or any Affiliate of a Lender of amounts available to be applied pursuant to clauses “FOURTH” and
“SIXTH” above; and (iii) to the extent that any amounts available for distribution pursuant to clause “SIXTH” above are attributable to the issued but undrawn amount of outstanding Letters of Credit, such amounts shall be
held by the Administrative Agent in a cash collateral account and applied (A) first, to reimburse the Issuing Bank from time to time for any drawings under such Letters of Credit and (B) then, following the expiration of all Letters of
Credit, to all other obligations of the types described in clauses “SIXTH” and “SEVENTH” above in the manner provided in this Section. 
 (e) To the extent that the Obligations are now or hereafter secured by property other than the Collateral described herein or by the Guarantee, endorsement or property of any other Person, the Administrative
Agent, at its option, may, and upon the written request of the Required Lenders, shall, proceed against such other Guarantee, endorsement or property upon the occurrence of an Event of Default, and the Administrative Agent shall have the right, in
its sole discretion, to determine which rights, security, liens, security interests or remedies the Administrative Agent shall at any time pursue, relinquish, subordinate, modify or take any other action with respect thereto, without in any way
modifying or affecting any of them or any of the Administrative Agent’s rights hereunder. 
 (f) Subject to Section 2.23(e),
the Administrative Agent is hereby authorized at any time or from time to time after the demand for payment of the Obligations pursuant to 
  

 76 








 Section 9.2(a), without prior notice to the Borrowers (any such notice being expressly waived by each Borrower), to
setoff and apply any deposit (general or special, time or demand, provisional or final) or investment account at any time held, including any certificate of deposit, and other indebtedness at any time owed by the Administrative Agent or any Lender,
whether or not any such deposit or indebtedness is then due, to or for the credit or account of any Borrower against any and all of the Obligations. The Administrative Agent shall give written notice of any setoff to the Borrowers. 
 (g) EACH BORROWER, HAVING KNOWLEDGE THAT IT MAY BE ENTITLED TO NOTICE AND A HEARING PRIOR TO REPOSSESSION OF THE COLLATERAL, WAIVES ANY RIGHT THAT
IT MAY HAVE TO NOTICE OF FORECLOSURE, TO ANY HEARING THAT MAY BE HELD RELATING TO FORECLOSURE, AND TO ANY NOTICE THAT MAY BE REQUIRED TO BE GIVEN BY THE ADMINISTRATIVE AGENT OR ANY LENDER PRIOR TO SUCH HEARING, OTHER THAN THE NOTICES OR HEARINGS
REQUIRED BY THE LOAN DOCUMENTS, THE UCC OR ANY OTHER APPLICABLE LAW. THE ADMINISTRATIVE AGENT, EACH LENDER AND EACH BORROWER EXPRESSLY WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION RELATING TO THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT. 
 (h) The Administrative Agent itself may perform or comply, or otherwise cause performance or compliance, for
the ratable benefit of the Lenders, with the obligations of a Borrower contained in this Agreement, including, without limitation, the obligations of each Borrower to defend and insure the Collateral. The expenses of the Administrative Agent
incurred in connection with such performance or compliance, together with interest thereon at the Federal Funds Rate plus 2%, from the date such expenses are paid until the same are repaid, shall be payable by the Borrowers to the Administrative
Agent on demand and shall constitute Obligations. 
 SECTION 10. The Administrative Agent. 
 10.1 Appointment of Administrative Agent. 
 (a) Each Lender irrevocably appoints SunTrust Bank as the Administrative Agent and authorizes it to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent under
this Agreement and the other Loan Documents, together with all such actions and powers that are reasonably incidental thereto. The Administrative Agent may perform any of its duties hereunder or under the other Loan Documents by or through any one
or more sub-agents or attorneys-in-fact appointed by the Administrative Agent. The Administrative Agent and any such sub-agent or attorney-in-fact may perform any and all of its duties and exercise its rights and powers through their respective
Related Parties. The exculpatory provisions set forth in this Article shall apply to any such sub-agent or attorney-in-fact and the Affiliate of the Administrative Agent, any such sub-agent and any such attorney-in-fact and shall apply to their
respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 
  

 77 








 (b) The Issuing Bank shall act on behalf of the Lenders with respect to any Letters of Credit
issued by it and the documents associated therewith until such time and except for so long as the Administrative Agent may agree at the request of the Required Lenders to act for the Issuing Bank with respect thereto; provided, that the Issuing Bank
shall have all the benefits and immunities (i) provided to the Administrative Agent in this Article with respect to any acts taken or omissions suffered by the Issuing Bank in connection with Letters of Credit issued by it or proposed to be
issued by it and the application and agreements for letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative Agent” as used in this Article included the Issuing Bank with respect to such acts or
omissions and (ii) as additionally provided in this Agreement with respect to the Issuing Bank. 
 10.2 Nature of Duties of
Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set forth in this Agreement and the other Loan Documents. Without limiting the generality of the foregoing, (a) the
Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except those discretionary rights and powers expressly contemplated by the Loan Documents that the Administrative Agent is required to exercise in writing by the Required Lenders (or such
other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 11.2(b)), and (c) except as expressly set forth in the Loan Documents, the Administrative Agent shall not have any duty to
disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the Administrative Agent or any of its Affiliates in any capacity. The
Administrative Agent shall not be liable for any action taken or not taken by it, its sub-agents or attorneys-in-fact with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary
under the circumstances as provided in Section 11.2(b)) or in the absence of its own gross negligence or willful misconduct or a breach by the Administrative Agent of its specific and express obligations to the Lenders under this Agreement as
determined by a final non-appealable judgment by a court of competent jurisdiction. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents or attorneys-in-fact selected by it with reasonable care. The
Administrative Agent shall not be deemed to have knowledge of any Default or Event of Default unless and until written notice thereof (which notice shall include an express reference to such event being a “Default” or “Event of
Default” hereunder) is given to the Administrative Agent by the Company or any Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation
made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the
covenants, agreements, or other terms and conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the
satisfaction of 
  

 78 








 any condition set forth in Section 8 or elsewhere in any Loan Document, other than to confirm receipt of items
expressly required to be delivered to the Administrative Agent. The Administrative Agent may consult with legal counsel (including counsel for the Borrowers) concerning all matters pertaining to such duties. The Administrative Agent agrees to
exercise such care in performing its duties hereunder as it would for loans for its sole benefit. 
 10.3 Lack of Reliance on the
Administrative Agent. Each of the Lenders, the Swingline Lender and the Issuing Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each of the Lenders, the Swingline Lender and the Issuing Bank also acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, continue to make its own decisions in taking or not taking of any action under or based on this Agreement, any related agreement or
any document furnished hereunder or thereunder. 
 10.4 Certain Rights of the Administrative Agent. If the Administrative Agent
shall request instructions from the Required Lenders with respect to any action or actions (including the failure to act) in connection with this Agreement, the Administrative Agent shall be entitled to refrain from such act or taking such act,
unless and until it shall have received instructions from such Lenders, and the Administrative Agent shall not incur liability to any Person by reason of so refraining in the absence of the Administrative Agent’s own gross negligence or willful
misconduct as determined by a final non-appealable judgment by a court of competent jurisdiction. Without limiting the foregoing, no Lender shall have any right of action whatsoever against the Administrative Agent as a result of the Administrative
Agent acting or refraining from acting hereunder in accordance with the instructions of the Required Lenders where required by the terms of this Agreement in the absence of the Administrative Agent’s own gross negligence or willful misconduct
as determined by a final non-appealable judgment by a court of competent jurisdiction. 
 10.5 Reliance by Administrative
Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and
to have been signed, sent or made by the proper Person. The Administrative Agent may also rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person and shall not incur any liability for relying
thereon. The Administrative Agent may consult with legal counsel (including counsel for the Borrowers), independent public accountants and other experts selected by it and shall not be liable for any action taken or not taken by it in accordance
with the advice of such counsel, accountants or experts. 
 10.6 The Administrative Agent in its Individual Capacity. The bank
serving as the Administrative Agent shall have the same rights and powers under this Agreement and any other Loan Document in its capacity as a Lender as any other Lender and may exercise or refrain from exercising the same as though it were not the
Administrative Agent; and the terms “Lenders”, “Required Lenders”, “holders of Notes”, or any similar terms shall, unless the context clearly 
  

 79 








 otherwise indicates, include the Administrative Agent in its individual capacity. The bank acting as the Administrative
Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrowers or any Subsidiary or Affiliate of the Borrowers as if it were not the Administrative Agent hereunder. 
 10.7 Successor Administrative Agent. 
 (a) The Administrative Agent may resign at any time by giving notice thereof to the Lenders and the Company. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent, subject to
the approval by the Company provided that no Event of Default shall exist at such time. If no successor Administrative Agent shall have been so appointed, and shall have accepted such appointment within 30 days after the retiring Administrative
Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent, which shall be a commercial bank organized under the laws of the United States of
America or any state thereof or a bank which maintains an office in the United States, having a combined capital and surplus of at least $500,000,000. 
 (b) Upon the acceptance of its appointment as the Administrative Agent hereunder by a successor, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. If within 45 days after written notice is given
of the retiring Administrative Agent’s resignation under this Section 10.7 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then on such 45th day (i) the retiring Administrative Agent’s resignation shall become effective, (ii) the retiring Administrative Agent shall thereupon be
discharged from its duties and obligations under the Loan Documents and (iii) the Required Lenders shall thereafter perform all duties of the retiring Administrative Agent under the Loan Documents until such time as the Required Lenders appoint
a successor Administrative Agent as provided above. After any retiring Administrative Agent’s resignation hereunder, the provisions of this Article shall continue in effect for the benefit of such retiring Administrative Agent and its
representatives and agents in respect of any actions taken or not taken by any of them while it was serving as the Administrative Agent. 
 10.8 Authorization to Execute other Loan Documents; Collateral. 
 (a) Each Lender authorizes the Administrative
Agent to enter into each of the Loan Documents to which it is a party and to take all action contemplated by such Loan Documents. Each Lender agrees that no Lender, other than the Administrative Agent acting on behalf of all Lenders, shall have the
right individually to seek to realize upon the security granted by any Loan Document, it being understood and agreed that such rights and remedies may be exercised solely by the Administrative Agent for the benefit of the Lenders, upon the terms of
the Loan Documents. 
  

 80 








 (b) In the event that any Collateral is pledged by any Person as collateral security for the
Obligations, the Administrative Agent is hereby authorized to execute and deliver on behalf of the Lenders any Loan Documents necessary or appropriate to grant and perfect a Lien on such Collateral in favor of the Administrative Agent on behalf of
the Lenders. 
 (c) The Lenders hereby authorize the Administrative Agent, at its option and in its discretion, to release any Lien
granted to or held by the Administrative Agent upon any Collateral (i) upon termination of the Commitments and payment and satisfaction of all of the Obligations or the transactions contemplated hereby; (ii) as permitted by, but only in
accordance with, the terms of the applicable Loan Document; (iii) if approved, authorized or ratified in writing by the Required Lenders, unless such release is required to be approved by all of the Lenders hereunder; (iv) the release of a
Lien granted by a Subsidiary in the case of the sale of the Subsidiary permitted by the terms of this Agreement; or (v) the release of any Lien on any assets which are Disposed of in accordance with the terms of this Agreement. Upon request by
the Administrative Agent at any time, the Lenders will confirm in writing the Administrative Agent’s authority to release particular types or items of Collateral pursuant to this Section 10.8(c). 
 (d) Upon any sale or transfer of assets constituting Collateral which is expressly permitted pursuant to the terms of any Loan Documents, or
consented to in writing by the Required Lenders, and upon at least ten (10) Business Days’ prior written request by the Company, the Administrative Agent shall (and is hereby irrevocably authorized by the Lenders to) execute such documents
as may be necessary to evidence the release of the Liens granted to the Administrative Agent for the benefit of the Lenders, upon the Collateral that was sold or transferred; provided, however, that (i) the Administrative
Agent shall not be required to execute any such document on terms which, in the Administrative Agent’s opinion, would expose the Administrative Agent to liability or create any obligation or entail any consequence other than the release of such
Liens without recourse or warranty, and (ii) such release shall not in any manner discharge, affect or impair the Obligations or any Liens upon (or obligations of any Borrower) in respect of) all interests retained by any Borrower including
(without limitation) the proceeds of the sale, all of which shall continue to constitute part of the Collateral. 
 10.9 Benefits of
Article 10. None of the provisions of this Article 10 shall inure to the benefit of any Borrower or of any Person other than Administrative Agent and each of the Lenders and their respective successors and permitted assigns. Accordingly,
neither the Borrowers nor any Person other than Administrative Agent and the Lenders (and their respective successors and permitted assigns) shall be entitled to rely upon, or to raise as a defense, the failure of the Administrative Agent or any
Lenders to comply with the provisions of this Article 10.

 (b) Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All such notices and other communications to any party shall be effective when received by such Person at its address specified in this Section 11.1, or upon refusal to accept
receipt of such notice. 
 (c) Any agreement of the Administrative Agent and the Lenders herein to receive certain notices by
telephone or facsimile is solely for the convenience and at the request of the Company. The Administrative Agent and the Lenders shall be entitled to rely on the authority of any Person purporting to be a Person authorized by the Company and any
other Borrower to give such notice and the Administrative Agent and Lenders shall not have any liability to the Borrowers or other Person on account of any action taken or not taken by the Administrative Agent or the Lenders in reliance upon such
telephonic or facsimile notice. The joint and several obligations of the Borrowers to repay the Loans and all other Obligations hereunder shall not be affected in any way or to any extent by any failure of the Administrative Agent and the Lenders to
receive written confirmation of any telephonic or facsimile notice or the receipt by the Administrative Agent and the Lenders of a confirmation which is at variance with the terms understood by the Administrative Agent and the Lenders to be
contained in any such telephonic or facsimile notice. 
 11.2 Waiver; Amendments. 
 (a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder or any other Loan
Document, and no course of dealing between the Borrowers and the Administrative Agent or any Lender, shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power or any abandonment or discontinuance of steps
to enforce such right or power, preclude any other or further exercise thereof or the exercise of any other right or power hereunder or thereunder. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder and
under the other Loan Documents are cumulative and are not exclusive of any rights or remedies provided by law. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrowers therefrom shall in
any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of
the foregoing, the making of a Loan or the issuance of a Letter of Credit shall not be construed as a waiver of any Default or Event of Default, regardless of whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or
knowledge of such Default or Event of Default at the time. 
 (b) No amendment or waiver of any provision of this Agreement or the
other Loan Documents, nor consent to any departure by the Borrowers therefrom, shall in any event be effective unless the same shall be in writing and signed by the Borrowers and the Required Lenders and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which given; provided, that no amendment or waiver shall: (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the
principal amount of any Loan or unreimbursed LC Disbursement or reduce the rate of interest 
  

 83 








 thereon, or reduce any fees payable hereunder, or change the method of calculating any of the foregoing, without the
written consent of each Lender affected thereby, (iii) postpone the date fixed for any payment of any principal of, or interest on, any Loan or unreimbursed LC Disbursement or interest thereon or any fees hereunder or reduce the amount of,
waive or excuse any such payment, or postpone the scheduled date for the termination or reduction of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.23(d) or 2.23(e), or any other
provision hereof relating to pro rata sharing of payments among the Lenders, in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender affected thereby, (v) change any of the
provisions of this Section or the definition of “Required Lenders,” or any other provision hereof specifying the number or percentage of Lenders which are required to waive, amend or modify any rights hereunder or make any determination or
grant any consent hereunder, without the consent of each Lender; (vi) release Collateral securing any of the Obligations or agree to subordinate any Lien in such Collateral to any other creditor of a Borrower or any Subsidiary without the
consent of each Lender, other than Collateral that the Borrowers are entitled to sell or otherwise dispose of pursuant to Section 6.7 and other Collateral with an aggregate value not to exceed $1,000,000 in any fiscal year of the Company;
(vii) consent to any assignment by any Borrower of its rights or obligations hereunder without the consent of each Lender, (vii) increase the aggregate of all Commitments (other than pursuant to Section 2.7) without the consent of all
of the Lenders; or (viii) if there are any guarantors of the Obligations at any time, release any such Guarantor without the consent of all Lenders; provided further, that no such agreement shall amend, modify or otherwise affect the
rights, duties or obligations of the Administrative Agent, the Swingline Lender or the Issuing Bank without the prior written consent of such Person. Each Lender shall reply within ten (10) Business Days after the Administrative Agent’s
written request for approval action to be taken by it or any Lenders hereunder, or such lesser time as may be reasonably determined by the Administrative Agent due to time constraints in the Loan Documents and specified in the request for approval.

 11.3 Expenses; Indemnification. 
 (a) The Borrowers shall pay (i) all reasonable, out-of-pocket costs and expenses of the Administrative Agent and SunTrust Capital Markets, Inc., including the reasonable fees, charges and disbursements of
counsel for the Administrative Agent and SunTrust Capital Markets, Inc., in connection with the syndication of the credit facilities provided for herein, the preparation and administration of the Loan Documents and any amendments, modifications or
waivers thereof (whether or not the transactions contemplated in this Agreement or any other Loan Document shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance,
amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket costs and expenses (including, without limitation, the reasonable fees, charges and disbursements of one set of outside
counsel for the Administrative Agent and the Lenders, as selected by the Administrative Agent, including special insolvency counsel and local counsel, but not separate counsel for any Lender) incurred by the Administrative Agent, the Issuing Bank or
any Lender in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans made or any Letters of Credit issued hereunder, including all such
out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit. 
  

 84 








 (b) The Borrowers shall indemnify the Administrative Agent (and any sub-agent thereof), each
Lender and the Issuing Bank, each Affiliate of such Person, and the partners, directors, officers, employees, agents and advisors of such Person and of such Person’s Affiliates (each such Person being called an “Indemnitee”)
against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including the fees, charges and disbursements of any counsel for any Indemnitee), and shall indemnify and hold harmless each
Indemnitee from all fees and time charges and disbursements for attorneys who may be employees of any Indemnitee, incurred by any Indemnitee or asserted against any Indemnitee by any third party or by a Borrower arising out of, in connection with,
or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or
thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or Letter of Credit or the use or proposed use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment
under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property
owned or operated by the Company or any of its Subsidiaries, or any Environmental Liability related in any way to the Company or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating
to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by a Borrower, and regardless of whether any Indemnitee is a party thereto, provided that such indemnity shall not, as to any
Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or
willful misconduct of such Indemnitee or (y) result from a claim brought by the Borrowers against an Indemnitee for material breach of such Indemnitee’s material obligations hereunder or under any other Loan Document which breach continues
after notice thereof has been given to such Indemnitee by the Borrowers, if the Borrowers have obtained a final and nonappealable judgment in their favor on such claim as determined by a court of competent jurisdiction. 
 (c) To the extent that the Borrowers fail to pay any amount required to be paid to the Administrative Agent, the Issuing Bank or the Swingline
Lender under clauses (a) or (b), each Lender severally agrees to pay to the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be, such Lender’s Aggregate Exposure Percentage (determined as of the time that the
unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided, that the unreimbursed expense or indemnified payment, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against
the Administrative Agent, the Issuing Bank or the Swingline Lender in its capacity as such. 
 (d) To the extent permitted by
applicable law, the parties hereto shall not assert, and hereby waive, any claim against any other party hereto, on any theory of liability, for 
  

 85 








 special, indirect, consequential or punitive damages (as opposed to actual or direct damages) arising out of, in
connection with or as a result of, this Agreement or any agreement or instrument contemplated hereby, the transactions contemplated therein, any Loan or any Letter of Credit or the use of proceeds thereof. 
 (e) All amounts due under this Section shall be payable promptly after written demand therefor. 
 11.4 Successors and Assigns. 
 (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that no Borrower may assign or transfer any of its rights hereunder without
the prior written consent of each Lender (and any attempted assignment or transfer by a Borrower without such consent shall be null and void). 
 (b) Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including all or a portion of its Commitment and the Loans, the
Swingline Exposure and LC Exposure at the time owing to or held by it); provided, that (i) except in the case of an assignment to a Lender or an Affiliate of a Lender, the Company and the Administrative Agent (and, in the case of an
assignment of all or a portion of a Commitment or any Lender’s obligations in respect of its LC Exposure or Swingline Exposure, the Issuing Bank and the Swingline Lender) must give their prior written consent (which consent shall not be
unreasonably withheld or delayed if the assignment is to a commercial bank or financial institution organized under the laws of the United States or a state thereof), (ii) except in the case of an assignment to a Lender or an Affiliate of a
Lender or an assignment of the entire amount of the assigning Lender’s Commitment hereunder or an assignment while an Event of Default has occurred and is continuing, the amount of the Commitment of the assigning Lender subject to each such
assignment (determined as of the date an assignment and acceptance agreement, in form and substance satisfactory to the Administrative Agent, with respect to such assignment is delivered to the Administrative Agent) shall not be less than $1,000,000
(unless the Company and the Administrative Agent shall otherwise consent), (iii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement and
the other Loan Documents with respect to any Commitment and the Loans related thereto, (iv) the assigning Lender and the assignee shall execute and deliver to the Administrative Agent an assignment and acceptance agreement, in form and
substance satisfactory to the Administrative Agent, together with a processing and recordation fee payable by the assigning Lender or the assignee (as determined between such Persons) in an amount equal to $3,500, and (v) such assignee, if it
is not a Lender, shall deliver to the Administrative Agent all information reasonably requested by the Administrative Agent; provided, that any consent of the Company otherwise required hereunder shall not be required if an Event of Default
has occurred and is continuing. Upon the execution and delivery of the assignment and acceptance agreement and payment by such assignee to the assigning Lender of an amount equal to the purchase price agreed between such Persons, and the granting of
the consents required 
  

 86 








 herein, such assignee shall become a party to this Agreement and any other Loan Documents to which such assigning Lender
is a party and, to the extent of such interest assigned by such assignment and acceptance agreement, shall have the rights and obligations of a Lender under this Agreement, and the assigning Lender shall be released from its obligations hereunder to
a corresponding extent (and, in the case of an assignment and acceptance agreement covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be
entitled to the benefits of Sections 2.17, 2.18, 2.19 and 11.3 with respect to any period of time during which it was a Lender hereunder). Upon the consummation of any such assignment hereunder, the assigning Lender, the Administrative Agent and the
Borrowers shall make appropriate arrangements to have new Notes issued if so requested by either or both the assigning Lender or the assignee. Any assignment or other transfer by a Lender that does not fully comply with the terms of this clause
(b) shall be treated for purposes of this Agreement as a sale of a participation pursuant to clause (c) below. 
 (c) Any Lender
may at any time, without the consent of the Borrowers, the Administrative Agent, the Issuing Bank or the Swingline Lender, sell participations to one or more banks or other financial institutions (a “Participant”) in all or a
portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment, the Loans owing to it and its LC Exposure); provided, that (i) such Lender’s obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of its obligations hereunder, and (iii) the Borrowers, the Administrative Agent, the Swingline Lender, the
Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. Any agreement between such Lender and the
Participant with respect to such participation shall provide that such Lender shall retain the sole right and responsibility to enforce this Agreement and the other Loan Documents and the right to approve any amendment, modification or waiver of
this Agreement and the other Loan Documents; provided, that such participation agreement may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver of this Agreement described
in the first proviso of Section 11.2(b) that affects the Participant. Each Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.17 and 2.18 to the same extent as if it were a Lender hereunder and had acquired
its interest by assignment pursuant to paragraph (b); provided, that no Participant shall be entitled to receive any greater payment under Sections 2.17 or 2.18 than the applicable Lender would have been entitled to receive with respect to
the participation sold to such Participant unless the sale of such participation is made with the Company’s prior written consent and such Participant shall be subject to the provisions of Section 2.24(c). A Participant that would be a
Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.19 unless such Participant agrees, for the benefit of the Borrowers, to comply with Section 2.19(e) as though it were a Lender hereunder, provided, that
no Participant shall be entitled to receive any greater amount pursuant to such Section 2.19 than the transferor Lender would have been entitled to receive in respect of the amount for the participation transferred by such Lender to such
Participant has no such transfer occurred, and such Participant shall be subject to the provisions of Section 2.24(c). 
  

 87 








 (d) Any Lender may at any time pledge or assign a security interest in all or any portion of its
rights under this Agreement and its Notes (if any) to secure its obligations to a Federal Reserve Bank without complying with this Section; provided, that no such pledge or assignment shall release a Lender from any of its obligations
hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 
 (e) Notwithstanding anything to the
contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle organized or otherwise formed under the laws of the United States or any State thereof (an “SPV”),
identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrowers, the option to provide to the Borrowers all or any part of any Loan that such Granting Lender would otherwise be obligated to make
to the Borrowers pursuant to this Agreement; provided, that (i) nothing herein shall constitute a commitment by any SPV to make any Loan and (ii) if an SPV elects not to exercise such option or otherwise fails to provide all or any
part of any Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. As between the Granting Lender and the SPV, the Granting Lender shall retain the sole right and responsibility to enforce this Agreement or any
other Loan Document and the right to approve any amendment, modification or waiver hereof or thereof. The making of a Loan by an SPV hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if such Loan were made by
such Granting Lender. Each party hereto hereby agrees that no SPV shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing,
each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any
SPV, it will not institute against, or join any other person in instituting against, such SPV any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State. Notwithstanding any
provision to the contrary in this Section 11.4, any SPV may (i) with notice to, but without the prior written consent of, the Borrowers and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of
its interests in any Loans to the Granting Lender or to any financial institutions (consented to by the Company and the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPV to support the funding or
maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPV.
As this clause (e) applies to any particular SPV, this Section may not be amended without the written consent of such SPV. 
 11.5
Governing Law; Jurisdiction; Consent to Service of Process. 
 (a) This Agreement and the other Loan Documents shall be
construed in accordance with and be governed by the law (without giving effect to the conflict of law principles thereof) of the State. 
  

 88 








 (b) Each Borrower hereby irrevocably and unconditionally submits, for itself and its property, to
the non-exclusive jurisdiction of the United States District Court of the Eastern District of Virginia, and of any state court of the Commonwealth of Virginia and any appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or any other Loan Document or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims
in respect of any such action or proceeding may be heard and determined in such Virginia state court or, to the extent permitted by applicable law, such Federal court. Each of the parties hereto agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Administrative Agent, the
Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against the Borrowers or their respective properties in the courts of any jurisdiction. 
 (c) Each Borrower irrevocably and unconditionally waives any objection which it may now or hereafter have to the laying of venue of any such
suit, action or proceeding described in paragraph (b) of this Section and brought in any court referred to in paragraph (b) of this Section. Each of the parties hereto irrevocably waives, to the fullest extent permitted by applicable law,
the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
 (d) Each party to this
Agreement irrevocably consents to the service of process in the manner provided for notices in Section 11.1. Nothing in this Agreement or in any other Loan Document will affect the right of any party hereto to serve process in any other manner
permitted by law. 
 (e) The representations, warranties, covenants and agreements contained in this Agreement shall be deemed to have
been given and undertaken by the Borrowers jointly and severally. 
 11.6 WAIVER OF JURY TRIAL. EACH PARTY HERETO IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR
THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT
OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION. 
  

 89 








 11.7 Right of Setoff. In addition to any rights now or hereafter granted under applicable
law and not by way of limitation of any such rights, each Lender and the Issuing Bank shall have the right, subject to Section 2.23(e), at any time or from time to time upon the occurrence and during the continuance of an Event of Default and
the demand for payment of the Obligations pursuant to Section 9.2(a), without prior notice to the Borrowers, any such notice being expressly waived by the Borrowers to the extent permitted by applicable law, to set off and apply against all
deposits (general or special, time or demand, provisional or final) of the Borrowers at any time held or other obligations at any time owing by such Lender or the Issuing Bank to or for the credit or the account of the Borrowers against any and all
Obligations held by such Lender or the Issuing Bank, as the case may be, irrespective of whether such Lender or the Issuing Bank shall have made demand hereunder and although such Obligations may be unmatured. Each Lender and the Issuing Bank agree
promptly to notify the Administrative Agent and the Borrowers after any such set-off and any application made by such Lender and the Issuing Bank, as the case may be; provided, that the failure to give such notice shall not affect the
validity of such set-off and application. 
 11.8 Counterparts; Integration. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts (including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. This Agreement, the other Loan Documents, and any
separate letter agreement(s) relating to any fees payable to the Administrative Agent constitute the entire agreement among the parties hereto and thereto regarding the subject matters hereof and thereof and supersede all prior agreements and
understandings, oral or written, regarding such subject matters. 
 11.9 Survival. All covenants, agreements, representations
and warranties made by the Borrowers herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the
execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing
Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest
on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.17, 2.18, 2.19,
11.3, 11.11 and Section 9 shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the
Commitments or the termination of this Agreement or any provision hereof. All representations and warranties made herein, in the certificates, reports, notices, and other documents delivered pursuant to this Agreement shall survive the execution and
delivery of this Agreement and the other Loan Documents, and the making of the Loans and the issuance of the Letters of Credit. 
 11.10
Severability. Any provision of this Agreement or any other Loan Document held to be illegal, invalid or unenforceable in any jurisdiction, shall, as to such jurisdiction, be 
  

 90 








 ineffective to the extent of such illegality, invalidity or unenforceability without affecting the legality, validity or
enforceability of the remaining provisions hereof or thereof; and the illegality, invalidity or unenforceability of a particular provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other
jurisdiction. 
 11.11 Confidentiality. Each of the Administrative Agent, the Issuing Bank and each Lender agrees to take
normal and reasonable precautions to maintain the confidentiality of any information provided to it by the Borrowers or any Subsidiary, except that such information may be disclosed (i) to any Affiliate of the Administrative Agent, the Issuing
Bank or any such Lender, and their respective accountants, legal counsel and other professional advisors (provided that all such Persons shall have agreed in writing to keep such information confidential in accordance with the terms of this
Section), (ii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iii) to the extent requested by any regulatory agency or governmental authority having jurisdiction over the disclosing
Administrative Agent, Issuing Bank or Lender, (iv) to the extent that such information becomes publicly available other than as a result of a breach of this Section, (v) in connection with the exercise of any remedy hereunder or any suit,
action or proceeding relating to this Agreement or the enforcement of rights hereunder, (vi) subject to provisions substantially similar to this Section 11.11, to any actual or prospective assignee or Participant, or (vii) with the
prior written consent of the Company. Non-public information with respect to the Borrowers or any Subsidiary which becomes available to the Administrative Agent, the Issuing Bank, any Lender or any Affiliate, or their accountants, legal counsel or
other professional advisors, of any of the foregoing from a source other than the Borrowers may be used by the recipient but not further disclosed, other than in compliance with to clause (i) above. Any Person required to maintain the
confidentiality of any information as provided for in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such information as such
Person would accord its own confidential information. 
 11.12 Interest Rate Limitation. Notwithstanding anything herein to the
contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which may be treated as interest on such Loan under applicable law (collectively, the “Charges”), shall exceed the maximum
lawful rate of interest (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by a Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of
this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the
Federal Funds Rate to the date of repayment, shall have been received by such Lender. 
 11.13 Captions. The captions of the
various sections and paragraphs of this Agreement have been inserted only for the purposes of convenience; such captions are not a part of this Agreement and shall not be deemed in any manner to modify, explain, enlarge or restrict any of the
provisions of this Agreement. 
  

 91 








 11.14 Use of Defined Terms. All terms defined in this Agreement shall have the defined
meanings when used in certificates, reports or other documents made or delivered pursuant to this Agreement, unless the context shall otherwise require. 
 11.15 Accounting Terms. Unless otherwise defined or specified herein, all accounting terms used herein shall be interpreted, all accounting determinations hereunder shall be made, and all financial
statements required to be delivered hereunder shall be prepared, in accordance with GAAP as in effect from time to time, applied on a basis consistent (except for such changes approved by the Company’s independent public accountants) with the
most recent audited consolidated financial statements of the Company delivered pursuant to Section 5.8(a); provided, that if the Company notifies the Administrative Agent that the Company wishes to amend any covenant in Section 7 to
eliminate the effect of any change in GAAP on the operation of such covenant (or if the Administrative Agent notifies the Company that the Required Lenders wish to amend Section 7 for such purpose), then the Company’s compliance with such
covenant shall be determined on the basis of GAAP in effect immediately before the relevant change in GAAP became effective, until either such notice is withdrawn or such covenant is amended in a manner satisfactory to the Company, the
Administrative Agent and the Required Lenders. 
 11.16 Patriot Act. The Administrative Agent and each Lender hereby notifies
the Borrowers that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies each
Borrower, which information includes the name and address of such Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify such Borrower in accordance with the Patriot Act. Each Borrower
shall, and shall cause each of its Subsidiaries to, provide to the extent commercially reasonable, such information and take such other actions as are reasonably requested by the Administrative Agent or any Lender in order to assist the
Administrative Agent and the Lenders in maintaining compliance with the Patriot Act.

 EXHIBIT B 
 COLLATERAL ASSIGNMENT, PATENT MORTGAGE 
 AND SECURITY AGREEMENT 
 This Collateral Assignment, Patent Mortgage and Security Agreement (the “Assignment”) dated as of the     
day of                     ,         , from
                            , a
             corporation (the “Assignor”), in favor of SUNTRUST BANK, a Georgia banking corporation (“Assignee”), as administrative agent for
the Lenders (as such term is defined in the Loan Agreement). 
 RECITALS 
 The Lenders and Assignee (as the Administrative Agent for the Lenders) have entered into a Loan and Security Agreement, dated as of March 14, 2006
(as amended, modified or supplemented from time to time, the “Loan Agreement,” the capitalized terms defined therein and not otherwise defined herein being used herein as therein defined) with Assignor and each other Borrower.
[Simultaneously herewith, Assignor shall enter into the Assumption Agreement, dated as of
                                , with the Lenders (as amended, modified or
supplemented from time to time, the “Assumption Agreement”), thereby becoming a Borrower under the Loan Agreement in accordance with the terms and conditions thereof, and, by its execution and delivery hereof, an Assignor.] It is a
condition precedent to the making of the Loans and the issuance of Letters of Credit by Assignee, the Lenders or the Issuing Bank, as applicable, under the Loan Agreement that Assignor shall have assigned certain property to Assignee (for the
ratable benefit of the Lenders and the Issuing Bank) in accordance with this Assignment. 
 NOW, THEREFORE, FOR VALUABLE CONSIDERATION,
THE RECEIPT AND SUFFICIENCY OF WHICH ARE ACKNOWLEDGED, THE PARTIES HERETO AGREE AS FOLLOWS: 
 SECTION 17. Assignment, Patent Mortgage and Grant
of Security Interest. As collateral security for the prompt and complete payment and performance of the Obligations (as defined below), Assignor hereby assigns, transfers, conveys and grants a security interest and mortgage to Assignee, for the
ratable benefit of the Lenders and the Issuing Bank, as security, but not as an ownership interest, in and to its entire right, title and interest in, to and under the following (all of which shall collectively be called the
“Collateral”): 
 17.1 All present and future United States copyright registrations owned by Assignor, including,
without limitation, the registered copyrights listed in Exhibit A-1 to this Assignment, as amended and supplemented from time to time (and including all of the exclusive rights afforded a copyright registrant in the United States under 17
U.S.C. §106 and any exclusive rights owned by Assignor which may in the future arise by act of Congress or otherwise) (collectively, the “Registered Copyrights”), and any and all royalties, payments, and other amounts payable
to Assignor in connection with the Registered Copyrights, together with all renewals and extensions of the Registered Copyrights, Assignor’s right to recover for all past, present, and future infringements of the Registered Copyrights, and all
Assignor’s computer programs, computer databases, computer program flow diagrams, source codes, object codes and all tangible property embodying or incorporating the Registered Copyrights, and all other rights of every kind whatsoever owned by
Assignor accruing thereunder or pertaining thereto; 







 17.2 All present and future accounts, accounts receivable and other rights to payment arising
from, in connection with or relating to the Copyrights; 
 17.3 All registered patents and like protections owned by Assignor
including, without limitation, improvements, divisions, continuations, renewals, reissues, extensions and continuations-in-part of the same, including without limitation the patents set forth on Exhibit B attached hereto as amended and
supplemented from time to time (collectively, the “Patents”), and any and all royalties, payments, and other amounts payable to Assignor in connection with the Patents, together with all renewals and extensions of the Patents, the
right of Assignor to recover for all past, present, and future infringements of the Patents, and all computer programs, computer databases, computer program flow diagrams, source codes, object codes and all tangible property of Assignor embodying or
incorporating the Patents, and all other rights of every kind whatsoever accruing thereunder or pertaining thereto; 
 17.4 Any
federally registered trademark and servicemark rights owned by Assignor and the entire goodwill of the business of Assignor connected with and symbolized by such trademarks, including without limitation those set forth on Exhibit C attached
hereto, as amended and supplemented from time to time (collectively, the “Trademarks”), and any and all royalties, payments, and other amounts payable to Assignor in connection with the Trademarks, together with all renewals and
extensions of the Trademarks, and the right of Assignor to recover for all past, present, and future infringements of the Trademarks; 
 17.5 Any and all claims of Assignor for damages by way of past, present and future infringements of any of the Copyrights, Patents and Trademarks included above, with the right, but not the obligation, to sue for and collect such
damages for said use or infringement of the intellectual property rights of Assignor identified above; 
 17.6 Assignor’s
interest in all licenses or other rights granted by Assignor to use any of the Copyrights, Patents or Trademarks, and all license fees and royalties owing to Assignor arising from such use to the extent permitted by such license or rights;

 17.7 All amendments, extensions, renewals and extensions of any of the Copyrights, Trademarks or Patents; and 
 17.8 All proceeds and products of the foregoing, including without limitation all payments under insurance or any indemnity or warranty payable in
respect of any of the foregoing. 
 THE INTEREST IN THE COLLATERAL BEING ASSIGNED HEREUNDER SHALL NOT BE CONSTRUED AS A CURRENT ASSIGNMENT, BUT AS A
CONTINGENT ASSIGNMENT TO SECURE ASSIGNOR’S OBLIGATIONS TO ASSIGNEE, THE LENDERS AND THE ISSUING BANK. 
 This Assignment secures the
payment of all of the Obligations. Without limiting the generality of the foregoing, this Assignment secures the payment of all amounts that constitute part of the Obligations and would be owed by Assignor to Assignee, the Lenders or the Issuing
Bank, as applicable, but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving Assignor. 
  

 2 








 SECTION 18. Authorization and Request. Assignor authorizes and requests that the Register of Copyrights and
the Commissioner of Patents and Trademarks record this conditional assignment. 
 SECTION 19. Covenants and
Warranties. Assignor represents, warrants, covenants and agrees as follows: 
 19.1 Assignor is now the sole owner of all material
items of Collateral, except for non-exclusive licenses granted by Assignor to its Customers in the ordinary course of business. 
 19.2
Listed on Exhibit A are all Copyrights owned by Assignor. Listed on Exhibit B are all Patents owned by Assignor. Listed on Exhibit C are all Trademarks owned by Assignor. As of the date hereof, the Assignor does not own or hold any
registered copyrights, patents or trademarks, other than as listed on Exhibits A, B and C attached hereto and other than such Intellectual Property that has not been used by the Borrowers in the past 12 months or from which no revenue in
excess of $100,000 has been derived in the past 12 months. 
 19.3 This Assignment creates, and in the case of after acquired
Collateral, this Assignment will create at the time Assignor first has rights in such after acquired Collateral, in favor of Assignee, for the ratable benefit of the Lenders and the Issuing Bank, a valid and perfected first priority security
interest in the Collateral in the United States securing the payment and performance of the Obligations upon making the filings referred to in clause (m) below. 
 SECTION 20. Assignee’s Rights. Assignee (for the ratable benefit of the Lenders and the Issuing Bank) shall have the right, but not the obligation, to take, at Assignor’s sole expense, any
actions that Assignor is required under this Assignment to take but which Assignor fails to take, after fifteen (15) days’ notice to Assignor. Assignor shall reimburse and indemnify Assignee (for the ratable benefit of the Lenders and the
Issuing Bank) for all reasonable costs and reasonable expenses incurred in the reasonable exercise of its rights under this Section SECTION 20. 
 SECTION 21. Inspection Rights. Assignor hereby grants to Assignee rights of inspection with respect to the Collateral, as more particularly set forth in Section 5.7 of the Loan Agreement. 
 SECTION 22. Further Assurances; Attorney in Fact. Assignor represents, warrants, covenants and agrees as follows: 
 22.1 Assignor will make, execute, acknowledge and deliver, and file and record in the proper filing and recording places in the United States, all
such instruments, including, appropriate financing and continuation statements and collateral agreements and filings with the United States Patent and Trademark Office and the Register of Copyrights, and take all such action as may reasonably be
deemed necessary or advisable, or as requested by Assignee, to perfect Assignee’s security interest (held for the ratable benefit of the Lenders and the Issuing Bank) in all Copyrights, Patents and Trademarks and otherwise to carry out the
intent and purposes of this Assignment, or for assuring and confirming to Assignee (for the ratable benefit of the Lenders and the Issuing Bank) the grant or perfection of a security interest in all Collateral. 
  

 3 








 22.2 Upon an Event of Default, Assignor hereby irrevocably appoints Assignee as its
attorney-in-fact, with full authority in the place and stead of Assignor and in the name of Assignor, Assignee or otherwise, from time to time in Assignee’s discretion, upon Assignor’s failure or inability to do so, to take any action and
to execute any instrument which Assignee may deem necessary or advisable to accomplish the purposes of this Assignment, including: 
 (a)
To modify, in its sole discretion, this Assignment without first obtaining Assignor’s approval of or signature to such modification by amending Exhibit A, , Exhibit B and Exhibit C, thereof, as appropriate, to include reference to any
right, title or interest in any Copyrights, Patents or Trademarks acquired by Assignor after the execution hereof or to delete any reference to any right, title or interest in any Copyrights, Patents or Trademarks in which Assignor no longer has or
claims any right, title or interest; and 
 (b) To file, in its sole discretion, one or more financing or continuation statements and
amendments thereto, relative to any of the Collateral without the signature of Assignor where permitted by law. 
 SECTION 23. Remedies. Upon
the occurrence and continuance of an Event of Default under the Loan Agreement, Assignee shall have the right to exercise, for the ratable benefit of the Lenders and the Issuing Bank, all the remedies of a secured party under the UCC, including,
without limitation, the right to: 
 23.1 Require Assignor to assemble any tangible property in which the Collateral is embodied and in
which Assignor has a security interest, held for the ratable benefit of the Lenders and the Issuing Bank, and to make it available to Assignee at a place designated by Assignee; 
 23.2 Exercise any and all rights as beneficial and legal owner of the Collateral (for the ratable benefit of the Lenders and the Issuing Bank),
including, without limitation, any and all consensual rights and powers with respect to the Collateral, and 
 23.3 Without limiting
the foregoing paragraphs (a) or (b), the Assignee shall have the right, for the ratable benefit of the Lenders and the Issuing Bank, to sell or assign or grant a license to use, or cause to be sold or assigned or grant a license to use any or
all of the Collateral or any part thereof, in each case, free of all rights and claims of Assignor therein and thereto, except to the extent such actions would violate restrictions against assignments contained in any Collateral in which
Assignor’s rights arise by contract or license. In that connection, Assignee shall have the right to cause any or all of the Collateral to be transferred of record into the name of Assignee or its nominee (for the ratable benefit of the Lenders
and the Issuing Bank) and the right to impose (i) such limitations and restrictions on the sale or assignment of the Collateral as Assignee may deem to be necessary or appropriate to comply with any law, rule or regulation having applicability
to such sale or assignment and (ii) requirements for any necessary governmental approvals. To the extent not inconsistent with any license or contract under which Assignor’s rights arise, Assignee (for the ratable benefit of the Lenders
and the Issuing Bank) shall have a nonexclusive, royalty-free license to use the Copyrights, Patents and Trademarks to the extent reasonably necessary to permit Assignee to exercise its rights and remedies (for the ratable benefit of the Lenders and
the Issuing Bank) upon the occurrence of an Event of Default. Assignor will pay any expenses (including reasonable attorney’s fees) incurred by Assignee in connection with the exercise of any of Assignee’s rights hereunder, including
without limitation any expense incurred in disposing of the Collateral. All of Assignee’s rights and remedies with respect to the Collateral shall be cumulative. 
  

 4 








 SECTION 24. Release. At such time as Assignors shall completely satisfy all of the Obligations, Assignee
shall execute and deliver to Assignors all assignments and other instruments as may be reasonably necessary or proper to terminate Assignee’s security interest (held for the ratable benefit of the Lenders and the Issuing Bank) and any
conditional assignment in the Collateral, subject to any disposition of the Collateral which may have been made by Assignee (for the ratable benefit of the Lenders and the Issuing Bank) pursuant to this Assignment. For the purpose of this
Assignment, the Obligations shall be deemed to continue if any Assignor enters into any bankruptcy or similar proceeding at a time when any amount paid to Assignee could be ordered to be repaid as a preference or pursuant to a similar theory, and
shall continue until it is finally determined that no such repayment can be ordered. 
 SECTION 25. No Waiver. No course of dealing between any
Assignor and Assignee, nor any failure to exercise nor any delay in exercising, on the part of Assignee, any right, power, or privilege under this Assignment or under the Loan Agreement or any other agreement, shall operate as a waiver. No single or
partial exercise of any right, power, or privilege under this Assignment or under the Loan Agreement or any other agreement by Assignee shall preclude any other or further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege by Assignee. 
 SECTION 26. Rights Are Cumulative. All of Assignee’s rights and remedies with respect to the
Collateral whether established by this Assignment, the Loan Agreement, or any other documents or agreements, or by law shall be cumulative and may be exercised concurrently or in any order. 
 SECTION 27. Course of Dealing. No course of dealing, nor any failure to exercise, nor any delay in exercising any right, power or privilege hereunder shall
operate as a waiver thereof. 
 SECTION 28. Attorneys’ Fees. If any action relating to this Assignment is brought by either party hereto
against the other party, the prevailing party shall be entitled to recover reasonable attorneys fees, costs and disbursements. 
 SECTION 29.
Amendments. This Assignment may be amended only by a written instrument signed by both parties hereto. To the extent that any provision of this Assignment conflicts with any provision of the Loan Agreement, the provision giving Assignee
greater rights or remedies shall govern, it being understood that the purpose of this Assignment is to add to, and not detract from, the rights granted to Assignee under the Loan Agreement. This Assignment, the Loan Agreement, and the documents
relating thereto comprise the entire agreement of the parties with respect to the matters addressed in this Assignment. 
 SECTION 30.
Severability. The provisions of this Assignment are severable. If any provision of this Assignment is held invalid or unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall affect only such
provision, or part thereof, in such jurisdiction, and shall not in any manner affect such provision or part thereof in any other jurisdiction, or any other provision of this Assignment in any jurisdiction. 
 SECTION 31. Counterparts. This Assignment may be executed in two or more counterparts, each of which shall be deemed an original but all of which together
shall constitute the same instrument. 
  

 5 








 SECTION 32. Governing Law and Jurisdiction. This Assignment shall be governed by the laws of the
Commonwealth of Virginia, without regard for choice of law provisions. Assignor and Assignee consent to the nonexclusive jurisdiction of any state or federal court located in Fairfax County, Virginia. 
 SECTION 33. Confidentiality. In handling any confidential information, Assignee (and its agents) hereby expressly agree to maintain the confidentiality of
such information in accordance with the provisions of Section 11.11 of the Loan Agreement. 
 SECTION 34. WAIVER OF RIGHT TO JURY TRIAL.
ASSIGNEE AND ASSIGNOR 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: (a) THIS ASSIGNMENT; OR (b) ANY OTHER PRESENT OR FUTURE INSTRUMENT OR AGREEMENT BETWEEN
ASSIGNEE AND ASSIGNOR; OR (c) ANY CONDUCT, ACTS OR OMISSIONS OF ASSIGNEE OR ASSIGNOR OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH ASSIGNEE OR ASSIGNOR; IN EACH OF THE FOREGOING CASES,
WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE.
