effective upon receipt by the Lender, shall be in writing or by telephone or telecopy transmission, and shall be confirmed in writing by the Borrower if so requested by the Lender,by (i) an Officer of the Borrower; or (ii) a Person
designated as the Borrowers agent by an Officer of the Borrower in a writing delivered to the Lender; or (iii) a Person whom the Lender reasonably believes to be an Officer of the Borrower or such a designated agent, which confirmation
shall specify whether the Advance shall be a Floating Rate Advance or a LIBOR Advance and, with respect to any LIBOR Advance, shall specify the principal amount of the LIBOR Advance and the Interest Period applicable thereto. The Borrower shall
repay all Advances even if the Lender does not receive such confirmation and even if the Person requesting an Advance was not in fact authorized to do so. Any request for an Advance, whether written or telephonic, shall be deemed to be a
representation by the Borrower that the conditions set forth in Section 4.2 have been satisfied as of the time of the request.

(c) Disbursement. Upon fulfillment of the applicable conditions set forth in Article IV, the Lender shall disburse the proceeds of the requested Advance by crediting the same to the Borrowers demand deposit account maintained
with the Lender unless the Lender and the Borrower shall agree in writing to another manner of disbursement.

Section 2.3 LIBOR Advances.

(a) Converting Floating Rate Advances to LIBOR Advances; Procedures. So long as no Default Period is in effect, the Borrower may convert
all or any part of the principal amount of any outstanding Floating Rate Advance into a LIBOR Advance by requesting that the Lender convert same no later than the Cut-off Time on the Business Day immediately preceding the Business Day on which the
Borrower wishes the conversion to become effective. Each request that conforms to the terms of this Agreement shall be effective upon receipt by the Lender and shall be confirmed in writing by the Borrower if the Lender so requests by any Officer or
designated agent identified in Section 2.2(b) or Person reasonably believed by the Lender to be such an Officer or designated agent, which request shall specify the Business Day on which the conversion is to occur, the total amount of the
Floating Rate Advance to be converted, and the applicable Interest Period. Each such conversion shall occur on a Business Day, and the aggregate amount of Floating Rate Advances converted to LIBOR Advances shall be in multiples of $100,000, with a
minimum conversion amount of at least $500,000.

(b) Procedures at End of an Interest Period. Unless the Borrower requests a
new LIBOR Advance in accordance with the procedures set forth below, or prepays the principal of an outstanding LIBOR Advance at the expiration of an Interest Period, the Lender shall automatically and without request of the Borrower convert each
LIBOR Advance to a Floating Rate Advance on the last day of the relevant Interest Period. So long as no Default exists, the Borrower may cause all or any part of any maturing LIBOR Advance to be renewed as a new LIBOR Advance by requesting that the
Lender continue the maturing Advance as a LIBOR Advance no later than the Cut-off Time on the Business Day immediately preceding the Business Day constituting the first day of the new Interest Period. Each such request shall be confirmed in writing
by the Borrower upon the Lenders request by any Officer or designated agent identified in Section 2.2(b), which confirmation shall be effective upon receipt by the Lender, and which shall specify the amount of the expiring LIBOR Advance
to be continued and the applicable Interest Period. Each new Interest Period shall begin on a Business Day and the amount of each LIBOR Advance shall be in multiples of $100,000, with a minimum Advance of at least $500,000.

(c) Setting and Notice of Rates. The Lender shall, with respect to any request for a LIBOR Advance under Section 2.2 or a conversion
or renewal of a LIBOR Advance under this Section 2.3, provide the Borrower with a LIBOR quote for each Interest Period identified by the Borrower on the Business Day on which the request was made, if the request is received by the Lender prior
to the Cut-off Time, or for requests received by the Lender after the Cut-off Time, on the next Business Day or on the Business Day on which the Borrower has requested that the LIBOR Advance be made effective. If the Borrower does not immediately
accept a LIBOR quote, the quoted rate shall expire and any subsequent request from Borrower for a LIBOR quote shall be subject to redetermination by the Lender of the applicable LIBOR for the LIBOR Advance.



16



---

(d) Taxes and Regulatory Costs. The Borrower shall pay the Lender with respect to any
Advance, upon demand and in addition to any other amounts due or to become due hereunder, any and all (i) withholdings, interest equalization taxes, stamp taxes or other taxes (except income and franchise taxes) imposed by any domestic or
foreign governmental authority and related in any manner to LIBOR, and (ii) future, supplemental, emergency or other changes in the LIBOR Reserve Percentage, assessment rates imposed by the Federal Deposit Insurance Corporation, or similar
requirements or costs imposed by any domestic or foreign governmental authority or resulting from compliance by the Lender with any request or directive (whether or not having the force of law) from any central bank or other governmental authority
and related in any manner to LIBOR to the extent they are not included in the calculation of LIBOR. In determining which of the foregoing are attributable to any LIBOR option available to the Borrower hereunder, any reasonable allocation made by the
Lender among its operations shall be conclusive and binding upon the Borrower.

Section 2.4 Letters of Credit.

(a) The Lender agrees, subject to the terms and conditions of this Agreement, to issue, at any time after the Funding Date and prior to
the Termination Date, one or more irrevocable standby or documentary letters of credit (each, a Letter of Credit) for the Borrowers account. The Lender will not issue any Letter of Credit if the face amount of the Letter of Credit
to be issued would exceed the lesser of:

(i) $1,000,000 less the L/C Amount, or

(ii) Availability.

Each
Letter of Credit, if any, shall be issued pursuant to a separate L/C Application made by the Borrower to the Lender, which must be completed in a manner satisfactory to the Lender. The terms and conditions set forth in each such L/C Application
shall supplement the terms and conditions of the Standby Letter of Credit Agreement.

(b) No Letter of Credit shall be
issued with an expiry date later than one year from the date of issuance or the Maturity Date in effect as of the date of issuance, whichever is earlier.

(c) Any request for issuance of a Letter of Credit shall be deemed to be a representation by the Borrower that the conditions set forth in Section 4.2 have been satisfied as of the date of the request.

(d) If a draft is submitted under a Letter of Credit when the Borrower is unable, because a Default Period exists or for
any other reason, to obtain a Revolving Advance to pay the Obligation of Reimbursement, the Borrower shall pay to the Lender on demand and in immediately available funds, the amount of the Obligation of Reimbursement together with interest, accrued
from the date of the draft until payment in



17



---

full at the Default Rate. Notwithstanding the Borrowers inability to obtain a Revolving Advance for any reason, the Lender is irrevocably authorized,
in its sole discretion, to make a Revolving Advance in an amount sufficient to discharge the Obligation of Reimbursement and all accrued but unpaid interest thereon.

Section 2.5 Special Account. If the Credit Facility is terminated for any reason while any Letter of Credit is outstanding, the Borrower shall thereupon pay the Lender in immediately available funds
for deposit in the Special Account an amount equal to the L/C Amount plus any anticipated fees and costs. If the Borrower fails to promptly make any such payment in the amount required hereunder, then the Lender may make a Revolving Advance against
the Credit Facility in an amount sufficient to fulfill this obligation and deposit the proceeds to the Special Account. The Special Account shall be an interest bearing account either maintained with the Lender or with a financial institution
acceptable to the Lender. Any interest earned on amounts deposited in the Special Account shall be credited to the Special Account. The Lender may apply amounts on deposit in the Special Account at any time or from time to time to the Indebtedness
in the Lenders sole discretion. The Borrower may not withdraw any amounts on deposit in the Special Account as long as the Lender maintains a security interest therein. The Lender agrees to transfer any balance in the Special Account to the
Borrower when the Lender is required to release its security interest in the Special Account when all Indebtedness has been repaid to the Lender.

Section 2.6 Structured Term Advance.

(a) The Lender agrees, subject to the
terms and conditions of this Agreement, to make a single advance to the Borrower on the Funding Date (the Structured Term Advance) in the amount of $3,000,000. The Borrowers obligation to pay the Structured Term Advance shall be
evidenced by the Term Note and shall be secured by the Collateral as provided in Article III.

(b) Upon fulfillment of
the applicable conditions set forth in Article IV, the Lender shall deposit the proceeds of the requested Structured Term Advance by crediting the same to the Borrowers demand deposit account specified in Section 2.2(c) unless the
Lender and the Borrower shall agree in writing to another manner of disbursement. Upon the Lenders request, the Borrower shall promptly confirm each telephonic request for a Structured Term Advance by executing and delivering an appropriate
confirmation certificate to the Lender. The Borrower shall be obligated to repay all Structured Term Advances notwithstanding the Lenders failure to receive such confirmation and notwithstanding the fact that the Person requesting the same was
not in fact authorized to do so. Any request for a Structured Term Advance, whether written or telephonic, shall be deemed to be a representation by the Borrower, upon which the Lender may rely, that the Borrower is in compliance with the conditions
set forth in Section 4.2 as of the time of the request.

Section 2.7 Payment of Term Note. The outstanding principal
balance of the Term Note shall be due and payable as follows:

(a) In equal quarterly installments of $333,350, beginning on
September 1, 2007, and on the same day of each quarter thereafter.



18



---

(b) All prepayments of principal with respect to the Term Note shall be applied to the
most remote principal installment or installments then unpaid.

(c) On December 1, 2009, the entire unpaid principal
balance of the Term Note and all unpaid interest accrued thereon shall also be fully due and payable.

Section 2.8 Interest;
Minimum Interest Charge; Default Interest Rate; Application of Payments; Participations; Usury.

(a) Interest.
Except as provided in Section 2.3, Section 2.8(c) and Section 2.8(f), the principal amount of each Advance shall bear interest as a Floating Rate Advance or a LIBOR Advance.

(b) Minimum Interest Charge. Notwithstanding any other terms of this Agreement to the contrary, but in all events subject to
Section 2.8(f), the Borrower shall pay to the Lender interest of not less than $8,000 per calendar month (the Minimum Interest Charge) during the term of this Agreement, and the Borrower shall pay any deficiency between the Minimum
Interest Charge and the amount of interest otherwise calculated under Section 2.8(a) on the first day of each month and on the Termination Date. When calculating this deficiency, the Default Rate, if applicable, shall be disregarded, and any
interest that accrues on a payment following its receipt on those days specified in Section 2.8(d) shall be included in determining the total amount of interest otherwise calculated under Section 2.8(a).

(c) Default Interest Rate. At any time during any Default Period or following the Termination Date, in the Lenders sole
discretion and without waiving any of its other rights or remedies, the principal of the Revolving Note and the Term Note shall bear interest at the Default Rate or such lesser rate as the Lender may determine, effective as of the first day of the
month in which any Default Period begins through the last day of such Default Period, or any shorter time period that the Lender may determine. The decision of the Lender to impose a rate that is less than the Default Rate or to not impose the
Default Rate for the entire duration of the Default Period shall be made by the Lender in its sole discretion and shall not be a waiver of any of its other rights and remedies, including its right to retroactively impose the full Default Rate for
the entirety of any such Default Period or following the Termination Date.

(d) Application of Payments.Payments
shall be applied to the Indebtedness on the Business Day of receipt by the Lender in the Lenders general account, but the amount of principal paid shall continue to accrue interest at the interest rate applicable under the terms of this
Agreement from the calendar day the Lender receives the payment, and continuing through the end of the second Business Day following receipt of the payment.

(e) Participations. If any Person shall acquire a participation in the Advances or the Obligation of Reimbursement, the Borrower
shall be obligated to the



19



---

Lender to pay the full amount of all interest calculated under this Section 2.8, along with all other fees, charges and other amounts due under this
Agreement, regardless if such Person elects to accept interest with respect to its participation at a lower rate than that calculated under this Section 2.8, or otherwise elects to accept less than its pro rata share of such fees, charges and
other amounts due under this Agreement.

(f) Usury. In any event no rate change shall be put into effect which would
result in a rate greater than the highest rate permitted by law. Notwithstanding anything to the contrary contained in any Loan Document, all agreements which either now are or which shall become agreements between the Borrower and the Lender are
hereby limited so that in no contingency or event whatsoever shall the total liability for payments in the nature of interest, additional interest and other charges exceed the applicable limits imposed by any applicable usury laws. If any payments
in the nature of interest, additional interest and other charges made under any Loan Document are held to be in excess of the limits imposed by any applicable usury laws, it is agreed that any such amount held to be in excess shall be considered
payment of principal hereunder, and the indebtedness evidenced hereby shall be reduced by such amount so that the total liability for payments in the nature of interest, additional interest and other charges shall not exceed the applicable limits
imposed by any applicable usury laws, in compliance with the desires of the Borrower and the Lender. This provision shall never be superseded or waived and shall control every other provision of the Loan Documents and all agreements between the
Borrower and the Lender, or their successors and assigns.

Section 2.9 Fees.

(a) Unused Line Fee. For the purposes of this Section 2.9(a), Unused Amount means the Maximum Line Amount reduced
by outstanding Revolving Advances and the L/C Amount. The Borrower agrees to pay to the Lender an unused line fee at the rate of 0.25 percent per annum on the average daily Unused Amount from the date of this Agreement to and including the
Termination Date, due and payable monthly in arrears on the first day of the month and on the Termination Date.

(b)
Collateral Exam Fees. The Borrower shall pay the Lender fees in connection with any collateral exams, audits or inspections conducted by or on behalf of the Lender of any Collateral or the Borrowers operations or business at the rates
established from time to time by the Lender as its collateral exam fees (which fees are currently $850 per day per collateral examiner), together with all actual out-of-pocket costs and expenses incurred in conducting any such collateral examination
or inspection.

(c) Letter of Credit Fees. The Borrower shall pay to the Lender a fee with respect to each Letter of
Credit that has been issued, if any, which fee shall be calculated on a per diem basis at an annual rate equal to 2.25 percent of the aggregate amount that may then be drawn under the Letter of Credit, assuming compliance with all conditions for
drawing (the Aggregate Face Amount), from and including the date of issuance of the Letter of Credit until the date that the Letter of Credit terminates or is returned to the Lender, which fee shall be due and payable monthly in arrears
on the first day of each month and on the date that the Letter of Credit terminates or is returned to the Lender;



20



---

provided, however, effective as of the first day of the fiscal quarter in which any Default Period begins through the last day of such Default
Period, or any shorter time period that the Lender may determine, in the Lenders sole discretion and without waiving any of its other rights and remedies, such fee shall increase to five percent of the Aggregate Face Amount. The foregoing fee
shall be in addition to any and all other fees, commissions and charges imposed by Lender with respect to or in connection with such Letter of Credit.

(d) Letter of Credit Administrative Fees. The Borrower shall pay all administrative fees charged by Lender in connection with the honoring of drafts under any Letter of Credit, amendments thereto, transfers
thereof and all other activity with respect to the Letters of Credit at the then  current rates published by Lender for such services rendered on behalf of customers of Lender generally.

(e) Termination and Line Reduction Fees. If (i) the Lender terminates the Credit Facility during a Default Period, or if
(ii) the Borrower terminates or reduces the Credit Facility on a date prior to the Maturity Date (other than as a direct consequence of Lenders failure to fund Advances under this Agreement when all conditions precedent to such Advance
have been satisfied), then the Borrower shall pay the Lender as liquidated damages and not as a penalty a termination fee in an amount equal to a percentage of the Maximum Line Amount (or the reduction of the Maximum Line Amount, as the case may be)
calculated as follows: (A) three percent if the termination or reduction occurs on or before the first anniversary of the Funding Date; (B) two percent if the termination or reduction occurs after the first anniversary of the Funding Date,
but on or before the second anniversary of the Funding Date; and (C) one percent if the termination or reduction occurs after the second anniversary of the Funding Date.

(f) Prepayment Fees and Contracted Funds Breakage Fees. The Borrower may prepay the principal amount of the Revolving Note and the
Term Note at any time in any amount, whether voluntarily or by acceleration, subject to the payment of fees as follows:

(i)
If the principal amount of the Revolving Note or the Term Note which is a LIBOR Advance is prepaid, the Borrower shall pay to the Lender immediately upon demand a contracted funds breakage fee equal to the sum of the discounted monthly differences
for each month from the month of prepayment through the month in which such Interest Period matures, calculated as follows for each such month:



| | (A) | Determine the amount of interest which would have accrued each month on the amount prepaid at the interest rate applicable to such amount had it remained outstanding until
the last day of the applicable Interest Period of such note.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (B) | Subtract from the amount determined in (A) above the amount of interest which would have accrued for the same month on the amount prepaid for the remaining term of such
Interest Period at LIBOR in effect on the date of prepayment for new loans made for such term and in a principal amount equal to the amount prepaid.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



21



---

| | (C) | If the result obtained in (B) for any month is greater than zero, discount that difference by LIBOR used in (B) above.
| | --- | ----------------------------------------------------------------------------------------------------------------------

The Borrower acknowledges that prepayment of the Revolving Note or the Term Note may result in the Lender incurring additional costs, expenses or
liabilities, and that it is difficult to ascertain the full extent of such costs, expenses or liabilities. The Borrower therefore agrees to pay the above-described prepayment fee and contracted funds breakage fee and agrees that said amounts
represent a reasonable estimate of the prepayment costs, contracted funds breakage costs, expenses and/or liabilities of the Lender.

(g) Waiver of Termination and Prepayment Fees. The Borrower will be excused from the payment of termination and prepayment fees otherwise due under this Agreement if such termination or prepayment is made because of refinancing
through another one of Lenders operating divisions.

(h) Overadvance Fees. Subject to Section 2.8(f), the
Borrower shall pay an Overadvance fee in the amount of $500.00 for each day or portion thereof during which an Overadvance exists, regardless of how the Overadvance arises or whether or not the Overadvance has been agreed to in advance by the Lender
(provided, however, that this fee does not apply to the Structured Term Advance). The acceptance of payment of an Overadvance fee by the Lender shall not be deemed to constitute either consent to the Overadvance or a waiver of the resulting Event of
Default, unless the Lender specifically consents to the Overadvance in writing and waives the Event of Default on whatever conditions the Lender deems appropriate.

(i) Other Fees and Charges. The Lender may from time to time impose additional fees and charges as consideration for Advances made
in excess of Availability or for other events that constitute an Event of Default or a Default hereunder, including fees and charges for the administration of Collateral by the Lender, and fees and charges for the late delivery of reports, which may
be assessed in the Lenders sole discretion on either an hourly, periodic, or flat fee basis, and in lieu of or in addition to imposing interest at the Default Rate.

Section 2.10 Time for Interest Payments; Payment on Non-Business Days; Computation of Interest and Fees.

(a) Time For Interest Payments. Accrued and unpaid interest accruing on Floating Rate Advances shall be due and payable on the first day of each month and on the Termination Date (each an Interest Payment
Date), or if any such day is not a Business Day, on the next succeeding Business Day. Interest will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of advance to the Interest
Payment Date. If an Interest Payment Date is not a Business Day, payment shall be made on the next succeeding Business Day. Interest accruing on



22



---

each LIBOR Advance shall be due and payable on the last day of the applicable Interest Period; provided, however, for Interest Periods that are
longer than one month, interest shall nevertheless be due and payable monthly on the last day of each month, and on the last day of the Interest Period.

(b) Payment on Non-Business Days. Whenever any payment to be made hereunder shall be stated to be due on a day which is not a Business Day, such payment may be made on the next succeeding Business Day, and such
extension of time shall in such case be included in the computation of interest on the Advances or the fees hereunder, as the case may be.

(c) Computation of Interest and Fees. Interest accruing on the outstanding principal balance of the Advances and fees hereunder outstanding from time to time shall be computed on the basis of actual number of
days elapsed in a year of 360 days.

Section 2.11 Lockbox and Collateral Account; Sweep of Funds.

(a) Lockbox and Collateral Account.

(i) The Borrower shall instruct all account debtors to pay all Accounts directly to the Lockbox. If, notwithstanding such instructions, the Borrower receives any payments on Accounts, the Borrower shall deposit such
payments into the Collateral Account. The Borrower shall also deposit all other cash proceeds of Collateral regardless of source or nature directly into the Collateral Account. Until so deposited, the Borrower shall hold all such payments and cash
proceeds in trust for and as the property of the Lender and shall not commingle such property with any of its other funds or property. All deposits in the Collateral Account shall constitute proceeds of Collateral and shall not constitute payment of
the Indebtedness.

(ii) All items deposited in the Collateral Account shall be subject to final payment. If any such item is
returned uncollected, the Borrower will immediately pay the Lender, or, for items deposited in the Collateral Account, the bank maintaining such account, the amount of that item, or such bank at its discretion may charge any uncollected item to the
Borrowers commercial account or other account. The Borrower shall be liable as an endorser on all items deposited in the Collateral Account, whether or not in fact endorsed by the Borrower.

(iii) If an increase in the Depository Bank Fees or Lockbox Processor Fees (as each is defined in the Wholesale Lockbox and Collection
Account Agreement) is not consistent with industry practice, the Borrower shall have the option to set up a new lockbox at another bank mutually acceptable to Lender and Borrower, subject to a control agreement being signed with the new bank, in
form and substance acceptable to Borrower and Lender.



23



---

(iv) To the extent that any provision of the Wholesale Lockbox and Collection Account
Agreement contradicts any provision of this Agreement, this Agreement shall control.

(b) Sweep of Funds. The Lender
shall from time to time, in accordance with the Wholesale Lockbox and Collection Account Agreement, cause funds in the Collateral Account to be transferred to the Lenders general account for payment of the Indebtedness. Amounts deposited in
the Collateral Account shall not be subject to withdrawal by the Borrower, except after payment in full and discharge of all Indebtedness.

Section 2.12 Voluntary Prepayment; Reduction of the Maximum Line Amount; Termination of the Credit Facility by the Borrower. Except as otherwise provided herein, the Borrower may prepay the Advances in whole at any time or from
time to time in part. The Borrower may terminate the Credit Facility or reduce the Maximum Line Amount at any time if it (i) gives the Lender at least 90 days advance written notice prior to the proposed Termination Date, and (ii) pays the
Lender applicable termination, prepayment and contracted funds breakage fees, and Maximum Line Amount reduction fees in accordance with the terms of this Agreement. Any reduction in the Maximum Line Amount shall be in multiples of $500,000, and with
a minimum reduction of at least $500,000. If the Borrower terminates the Credit Facility or reduces the Maximum Line Amount to zero, all Indebtedness shall be immediately due and payable, and if the Borrower gives the Lender less than the required
90 days advance written notice, then the interest rate applicable to borrowings evidenced by Revolving Note shall be the Default Rate for the period of time commencing 90 days prior to the proposed Termination Date through the date that the Lender
actually receives such written notice. If the Borrower does not wish the Lender to consider renewal of the Credit Facility on the next Maturity Date, then the Borrower shall give the Lender at least 90 days written notice prior to the Maturity Date
that it will not be requesting renewal. If the Borrower fails to give the Lender such timely notice, then the interest rate applicable to borrowings evidenced by the Revolving Note shall be the Default Rate for the period of time commencing 90 days
prior to the Maturity Date through the date that the Lender actually receives such written notice.

Section 2.13 Mandatory
Prepayment. Without notice or demand, if the sum of the outstanding principal balance of the Revolving Advances plus the L/C Amount shall at any time exceed the Borrowing Base, the Borrower shall (i) first, immediately prepay the Revolving
Advances to the extent necessary to eliminate such excess; and (ii) if prepayment in full of the Revolving Advances is insufficient to eliminate such excess, pay to the Lender in immediately available funds for deposit in the Special Account an
amount equal to the remaining excess. Any voluntary or mandatory prepayment received by the Lender under this Agreement may be applied to the Indebtedness, in such order and in such amounts as the Lender in its sole discretion may determine from
time to time.

Section 2.14 Revolving Advances to Pay Indebtedness. Notwithstanding the terms of Section 2.1, the Lender
may, in its discretion at any time or from time to time, without the Borrowers request and even if the conditions set forth in Section 4.2 would not be satisfied, make a Revolving Advance in an amount equal to the portion of the
Indebtedness from time to time due and payable, and may deliver the proceeds of any such Revolving Advance to Wells Fargo Merchant Services, L.L.C. in satisfaction of any unpaid obligations due to Wells Fargo Merchant Services, L.L.C.



24



---

Section 2.15 Use of Proceeds. The Borrower shall use the proceeds of Advances and each Letter
of Credit for working capital purposes in the ordinary course of business.

Section 2.16 Liability Records. The Lender may
maintain from time to time, at its discretion, records as to the Indebtedness. All entries made on any such record shall be presumed correct until the Borrower establishes the contrary. Upon the Lenders demand, the Borrower will admit and
certify in writing the exact principal balance of the Indebtedness that the Borrower then asserts to be outstanding. Any billing statement or accounting rendered by the Lender shall be presumed to be correct absent manifest error.

ARTICLE III

SECURITY INTEREST;
OCCUPANCY; SETOFF

Section 3.1 Grant of Security Interest. The Borrower hereby pledges, assigns and grants to the
Lender, for the benefit of itself and as agent for Wells Fargo Merchant Services, L.L.C., a lien and security interest (collectively referred to as the Security Interest) in the Collateral, as security for the payment and performance of:
(a) all present and future Indebtedness of the Borrower to the Lender; (b) all obligations of the Borrower and rights of the Lender under this Agreement; and (c) all present and future obligations of the Borrower to the Lender of
other kinds relating to or arising under this Agreement. Upon request by the Lender, the Borrower will grant to the Lender, for the benefit of itself and as agent for Wells Fargo Merchant Services, L.L.C., a security interest in all commercial tort
claims that the Borrower may have against any Person.

Section 3.2 Notification of Account Debtors and Other Obligors. The
Lender may at any time (while a Default Period then exists) notify any account debtor or other Person obligated to pay any amount due with respect to any item of Collateral that such right to payment has been assigned or transferred to the Lender
for security and shall be paid directly to the Lender. The Borrower will join in giving such notice if the Lender so requests. At any time after the Borrower or the Lender gives such notice to an account debtor or other obligor, the Lender may, but
need not, in the Lenders name or in the Borrowers name, demand, sue for, collect or receive any money or property at any time payable or receivable on account of, or securing, any such right to payment, or grant any extension to, make
any compromise or settlement with or otherwise agree to waive, modify, amend or change the obligations (including collateral obligations) of any such account debtor or other obligor. During any Default Period, the Lender may, in the Lenders
name or in the Borrowers name, as the Borrowers agent and attorney-in-fact, notify the United States Postal Service to change the address for delivery of the Borrowers mail to any address designated by the Lender, otherwise
intercept the Borrowers mail, and receive, open and dispose of the Borrowers mail, applying all Collateral as permitted under this Agreement and holding all other mail for the Borrowers account or forwarding such mail to the
Borrowers last known address.

---

Section 3.3 Assignment of Insurance. As additional security for the payment and performance
of the Indebtedness, the Borrower hereby assigns to the Lender any and all monies (including proceeds of insurance and refunds of unearned premiums) due or to become due under, and all other rights of the Borrower with respect to, any and all
policies of insurance now or at any time hereafter covering the Collateral or any evidence thereof or any business records or valuable papers pertaining thereto, and the Borrower hereby directs the issuer of any such policy to pay all such monies
directly to the Lender. At any time (with respect to any foreign insurance policy), or during a Default Period (with respect to any insurance policy that is not a foreign insurance policy), the Lender may (but need not), in the Lenders name or
in the Borrowers name, execute and deliver proof of claim, receive all such monies, endorse checks and other instruments representing payment of such monies, and adjust, litigate, compromise or release any claim against the issuer of any such
policy. During any Default Period (with respect to any insurance policy that is not a foreign insurance policy) any monies received as payment for any loss under any insurance policy mentioned above (other than liability insurance policies) or as
payment of any award or compensation for condemnation or taking by eminent domain, shall be paid over to the Lender to be applied, at the option of the Lender, either to the prepayment of the Indebtedness or shall be disbursed to the Borrower under
staged payment terms reasonably satisfactory to the Lender for application to the cost of repairs, replacements, or restorations. Any such repairs, replacements, or restorations shall be effected with reasonable promptness and shall be of a value at
least equal to the value of the items or property destroyed prior to such damage or destruction.

Section 3.4 Occupancy.

(a) The Borrower hereby irrevocably grants to the Lender the right (to the extent permitted by applicable laws and any
related lease agreements) to take exclusive possession of the Premises at any time during a Default Period without notice or consent.

(b) The Lender may use the Premises only to hold, process, manufacture, sell, use, store, liquidate, realize upon or otherwise dispose of goods that are Collateral and for other purposes that the Lender may in good
faith deem to be related or incidental purposes.

(c) The Lenders right to hold the Premises shall cease and terminate
upon the earlier of (i) payment in full and discharge of all Indebtedness and termination of the Credit Facility, and (ii) final sale or disposition of all goods constituting Collateral and delivery of all such goods to purchasers.

(d) The Lender shall not be obligated to pay or account for any rent or other compensation for the possession, occupancy or
use of any of the Premises; provided, however, that if the Lender does pay or account for any rent or other compensation for the possession, occupancy or use of any of the Premises, the Borrower shall reimburse the Lender promptly for
the full amount thereof. In addition, the Borrower will pay, or reimburse the Lender for, all taxes, fees, duties, imposts, charges and expenses at any time incurred by or imposed upon the Lender by reason of the execution, delivery, existence,
recordation, performance or enforcement of this Agreement or the provisions of this Section 3.4.

Borrower hereby grants to the Lender a non-exclusive, worldwide and royalty-free license to use or otherwise exploit all Intellectual Property Rights of the Borrower for the purpose of: (a) completing the manufacture of any in-process materials

Section 3.7 Setoff. In the event of a Default, the Lender may at any time or from time
to time, at its sole discretion and without demand and without notice to anyone, setoff any liability owed to the Borrower by the Lender, whether or not due, against any Indebtedness, whether or not due. In addition, in the event of a Default, each
other Person holding a participating interest in any Indebtedness shall have the right to appropriate or setoff any deposit or other liability then owed by such Person to the Borrower, whether or not due, and apply the same to the payment of said
participating interest, as fully as if such Person had lent directly to the Borrower the amount of such participating interest.

Section 3.8 Collateral. This Agreement does not contemplate a sale of accounts, contract rights or chattel paper, and, as provided by law, the Borrower is entitled to any surplus



27



---

and shall remain liable for any deficiency. The Lenders duty of care with respect to Collateral in its possession (as imposed by law) shall be deemed
fulfilled if it exercises reasonable care in physically keeping such Collateral, or in the case of Collateral in the custody or possession of a bailee or other third Person, exercises reasonable care in the selection of the bailee or other third
Person, and the Lender need not otherwise preserve, protect, insure or care for any Collateral. The Lender shall not be obligated to preserve any rights the Borrower may have against prior parties, to realize on the Collateral at all or in any
particular manner or order or to apply any cash proceeds of the Collateral in any particular order of application. The Lender has no obligation to clean-up or otherwise prepare the Collateral for sale. The Borrower waives any right it may have to
require the Lender to pursue any third Person for any of the Indebtedness.

agreement, lease or instrument to which the Borrower is a party or by which it or its properties may be bound or affected; or (v) result in, or require, the creation or imposition of any Lien (other than the Security Interest) upon or with
respect to any of the properties now owned or hereafter acquired by the Borrower.

Section 5.4 Legal Agreements. This Agreement

Section 5.6 Financial Condition; No Adverse Change. The Borrower has furnished to the Lender its audited
financial statements for its fiscal year ended August 31, 2006, and unaudited financial statements for the fiscal-year-to-date period ended June 30, 2007, and those statements fairly present, on a consolidated basis, in all material
respects the Borrowers financial condition on the dates thereof and the results of its operations and cash flows for the periods then ended and were prepared in accordance with GAAP. Since the date of the most recent financial statements,
there has been no change in the Borrowers business, properties or condition (financial or otherwise) which has had or is reasonably likely to have a Material Adverse Effect.

Section 5.7 Litigation. There are no actions, suits or proceedings pending or, to the Borrowers knowledge, threatened against or
affecting the Borrower or any of its Affiliates or the properties of the Borrower or any of its Affiliates before any court or governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, which, if determined
adversely to the Borrower or any of its Affiliates, would have a Material Adverse Effect on the financial condition, properties or operations of the Borrower or any of its Affiliates.

Section 5.8 Regulation U. The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying
margin stock (within the meaning of Regulation U of the Board of Governors of the Federal Reserve System), and no part of the proceeds of any Advance will be used to purchase or carry any margin stock or to extend credit to others for the purpose of
purchasing or carrying any margin stock.

the proper authorities when due all federal, state and local taxes required to be withheld by each of them. The Borrower and its Affiliates have filed all federal, state and local tax returns which to the knowledge of the Officers of the Borrower or
any Affiliate, as the case may be, are required to be filed, and the Borrower and its Affiliates have paid or caused to be paid to the respective taxing authorities all taxes as shown on said returns or on any assessment received by any of them to
the extent such taxes have become due other than any tax the amount of which, applicability, or validity is being contested in good faith by appropriate proceedings and (x) for which proper reserves have been made, (y) there is no risk of
forfeiture of Collateral during the pendency of such action.

Section 5.10 Titles and Liens. The Borrower has good and
indefeasible title to, or valid leasehold interests in, all Collateral free and clear of all Liens other than Permitted Liens. No financing statement naming the Borrower as debtor is on file in any office except to perfect only Permitted Liens.

Section 5.11 Intellectual Property Rights.

(a) Owned Intellectual Property. The Borrower or a Subsidiary is the owner of record of the patents, applications for patents,
trademarks, applications to register trademarks, service marks, applications to register service marks, and copyrights set forth on Schedule 5.11 which has been provided to the Lender in a separate document



32



---

contemporaneously herewith (the Owned Intellectual Property). Except as disclosed on Schedule 5.11, (i) the Borrower owns the Owned
Intellectual Property free and clear of all restrictions (excluding non-exclusive licenses granted by the Borrower in the ordinary course of business), court orders, injunctions, decrees, writs or Liens other than Permitted Liens, whether by written
agreement or otherwise, (ii) no Person other than the Borrower owns or has been granted any right in the Owned Intellectual Property other than non-exclusive licenses granted to licensees in the ordinary course of the Borrowers business,
(iii) to the best knowledge of the Borrower, after due inquiry, all Owned Intellectual Property is valid, subsisting and enforceable and (iv) the Borrower has taken all commercially reasonable action necessary to maintain and protect the
Owned Intellectual Property.

(b) Agreements with Employees and Contractors. The Borrower has entered into a legally
enforceable agreement with each of its employees and subcontractors obligating each such Person to assign to the Borrower, without any additional compensation, any Intellectual Property Rights created, discovered or invented by such Person in the
course of such Persons employment or engagement with the Borrower (except to the extent prohibited by law), and further requiring such Person to cooperate with the Borrower, without any additional compensation, in connection with securing and
enforcing any Intellectual Property Rights therein except for the failure to obtain such agreement, which individually or in the aggregate would not result in a Material Adverse Effect; provided, however, that the foregoing shall not
apply with respect to employees and subcontractors whose job descriptions are of the type such that no such assignments are reasonably foreseeable.

(c) Intellectual Property Rights Licensed from Others. Schedule 5.11 is a complete list of all material agreements under which the Borrower has licensed Intellectual Property Rights from another Person
(Licensed Intellectual Property) other than readily available, non-negotiated licenses of computer software and other intellectual property used solely for performing accounting, word processing and similar administrative tasks
(Off-the-shelf Software) and a summary of any ongoing payments the Borrower is obligated to make with respect thereto. Except as disclosed on Schedule 5.11 and in written agreements, copies of which have been given to the Lender, the
Borrowers licenses to use the Licensed Intellectual Property are free and clear of all restrictions, Liens other than Permitted Liens, court orders, injunctions, decrees, or writs, whether by written agreement or otherwise. Except as disclosed
on Schedule 5.11, the Borrower is not obligated or under any liability whatsoever to make any payments of a material nature by way of royalties, fees or otherwise to any owner of, licensor of, or other claimant to, any material Intellectual
Property Rights.

(d) Other Intellectual Property Needed for Business. Except for Off-the-shelf Software and as
disclosed on Schedule 5.11, the Owned Intellectual Property and the Licensed Intellectual Property constitute all Intellectual Property Rights used or necessary to conduct the Borrowers business as it is presently conducted or as the Borrower
reasonably foresees conducting it.



33



---

(e) Infringement. Except as disclosed on Schedule 5.11, the Borrower has no
knowledge of, and has not received any written claim or notice alleging, any Infringement of another Persons Intellectual Property Rights (including any written claim that the Borrower must license or refrain from using the Intellectual
Property Rights of any third party).

benefits with respect to employees or former employees (other than benefits required under Section 601 of ERISA, Section 4980B of the IRC or applicable state law). Neither the Borrower nor any ERISA Affiliate has received any notice or has
any knowledge to the effect that it is not in full compliance with any of the requirements of ERISA, the IRC or applicable state law with respect to any Plan. To the knowledge of the Borrower, no Reportable Event exists in connection with any
Pension Plan. Each Plan which is intended to qualify under the IRC is so qualified, and no fact or circumstance exists which may have an adverse effect on the Plans tax-qualified status. Neither the Borrower nor any ERISA Affiliate has
(i) any accumulated funding deficiency (as defined in Section 302 of ERISA and Section 412 of the IRC) under any Plan, whether or not waived, (ii) any liability under Section 4201 or 4243 of ERISA for any withdrawal, partial
withdrawal, reorganization or other event under any Multiemployer Plan or (iii) any liability or knowledge of any facts or circumstances which could result in any liability to the Pension Benefit Guaranty Corporation, the Internal Revenue
Service, the Department of Labor or any participant in connection with any Plan (other than routine claims for benefits under the Plan).

Section 5.13 Default. The Borrower is in compliance with all provisions of all agreements, instruments, decrees and orders to which it is a party or by which it or its property is bound or affected, the breach or default of
which could have a Material Adverse Effect.

quantity as to create any material liability or obligation for either the Borrower or the Lender under the common law of any jurisdiction or under any Environmental Law, and no Hazardous Substances have ever been stored, buried, spilled, leaked,
discharged, emitted or released in, on or under the Premises in such a way as to create any such material liability.

(b)
Except as disclosed on Schedule 5.14, the Borrower has not disposed of Hazardous Substances in such a manner as to create any material liability under any Environmental Law.

(c) Except as disclosed on Schedule 5.14, there have not existed in the past, nor has the Borrower received written notice of any

with any Environmental Law or any license, permit or other authorization issued pursuant thereto.



34

the past always been conducted in material compliance with all Environmental Laws and all licenses, permits and other authorizations required pursuant to any Environmental Law and necessary for the lawful and efficient operation of such businesses
are in the Borrowers possession and are in full force and effect, nor has the Borrower been denied insurance on grounds related to potential environmental liability. Except as disclosed on Schedule 5.14, no permit required under any
Environmental Law is scheduled to expire within 12 months that the Borrower does not have a reasonable basis to believe will not be renewed on substantially similar terms and there is no threat in writing that any such permit will be withdrawn,
terminated, limited or materially changed.

Section 5.16 Financing Statements. The Borrower has authorized the filing of financing statements sufficient when filed to perfect the
Security Interest and the other security interests created by the Security Documents for the liens in the Collateral which may be perfected by filing such financing statements. When such financing statements are filed in the offices noted therein,
the Lender will have a valid and perfected security interest in all Collateral which is capable of being perfected by filing financing statements. None of the Collateral is or will become a fixture on real estate, unless a sufficient fixture filing
is in effect with respect thereto.

Section 5.17 Rights to Payment. Each right to payment and each instrument, document,
chattel paper and other agreement constituting or evidencing Collateral is (or, in the case of all future Collateral, will be when arising or issued) the valid, genuine and legally enforceable obligation, subject to no defense, setoff or
counterclaim, of the account debtor or other obligor named therein or in the Borrowers records pertaining thereto as being obligated to pay such obligation, subject to reserves that are customary in accordance with their past practice or
otherwise in the range of similar discounts in the industry.

all of the transactions contemplated in the Loan Documents, none of the Borrower or its Affiliates:

(p) There has occurred any breach, default or event of default by, or attributable to, any Affiliate under any agreement between the Affiliate and the Lender; or

Section 7.2 Rights and Remedies. During any Default Period, the Lender may exercise any or
all of the following rights and remedies:

(a) The Lender may, by notice to the Borrower, declare the Commitment to be
terminated, whereupon the same shall forthwith terminate;

(b) The Lender may, by notice to the Borrower, declare the
Indebtedness to be forthwith due and payable, whereupon all Indebtedness shall become and be forthwith due and payable, without presentment, notice of dishonor, protest or further notice of any kind, all of which the Borrower hereby expressly
waives;

(c) The Lender may, without notice to the Borrower and without further action, apply any and all money owing by the
Lender to the Borrower to the payment of the Indebtedness;

(d) The Lender may exercise and enforce any and all rights and
remedies available upon default to a secured party under the UCC, including the right to take possession of Collateral, or any evidence thereof, proceeding without judicial process or by judicial process (without a prior hearing or notice thereof,
which the Borrower hereby expressly waives) and the right to sell, lease or otherwise dispose of any or all of the Collateral (with or without giving any warranties as to the Collateral, title to the Collateral or similar warranties), and, in
connection therewith, the Borrower will on demand assemble the Collateral and make it available to the Lender at a place to be designated by the Lender which is reasonably convenient to both parties;

(e) The Lender may make demand upon the Borrower and, forthwith upon such demand, the Borrower will pay to the Lender in immediately
available funds for deposit in the Special Account pursuant to Section 2.5 an amount equal to the aggregate maximum amount available to be drawn under all Letters of Credit then outstanding, assuming compliance with all conditions for drawing
thereunder;

(f) The Lender may exercise and enforce its rights and remedies under the Loan Documents;

(g) The Lender may without regard to any waste, adequacy of the security or solvency of the Borrower, apply for the appointment of a
receiver of the Collateral, to which appointment the Borrower hereby consents, whether or not foreclosure proceedings have been commenced under the Security Documents and whether or not a foreclosure sale has occurred; and

(h) The Lender may exercise any other rights and remedies available to it by law, this Agreement or other Loan Documents.

Notwithstanding the foregoing, upon the occurrence of an Event of Default described in Section 7.1(f) or (g), the Indebtedness shall be immediately due and payable
automatically without presentment, demand, protest or notice of any kind. If the Lender sells any of the Collateral on credit, the Indebtedness will be reduced only to the extent of payments actually received. If the purchaser fails to pay for the
Collateral, the Lender may resell the Collateral and shall apply any proceeds actually received to the Indebtedness.

Section 7.3 Certain Notices. If notice to the Borrower of any intended disposition of
Collateral or any other intended action is required by law in a particular instance, such notice shall be deemed commercially reasonable if given (in the manner specified in Section 8.3) at least ten calendar days before the date of intended
disposition or other action.

ARTICLE VIII

MISCELLANEOUS

Section 8.1 No Waiver; Cumulative Remedies; Compliance with Laws.
No failure or delay by the Lender in exercising any right, power or remedy under the Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise
thereof or the exercise of any other right, power or remedy under the Loan Documents. The remedies provided in the Loan Documents are cumulative and not exclusive of any remedies provided by law. The Lender may comply with any applicable state or
federal law requirements in connection with a disposition of the Collateral and such compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral.

Section 8.2 Amendments, Etc. No amendment, modification, termination or waiver of any provision of any Loan Document or consent to any
departure by the Borrower therefrom or any release of a Security Interest shall be effective unless the same shall be in writing and signed by the Lender, and then such waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

Section 8.3 Notices; Communication of Confidential Information; Requests for Accounting. Except as otherwise expressly provided herein, all
notices, requests, demands and other communications provided for under the Loan Documents shall be in writing and shall be (a) personally delivered, (b) sent by first class United States mail, (c) sent by overnight courier of national
reputation, (d) transmitted by telecopy, or (e) sent as electronic mail, in each case delivered or sent to the party to whom notice is being given to the business address, telecopier number, or e mail address set forth below next to its
signature or, as to each party, at such other business address, telecopier number, or e mail address as it may hereafter designate in writing to the other party pursuant to the terms of this Section. All such notices, requests, demands and other
communications shall be deemed to be an authenticated record communicated or given on (a) the date received if personally delivered, (b) 3 days after deposit in the mail if delivered by mail, (c) the date delivered to the courier if
delivered by overnight courier, or (d) the date of transmission if sent by telecopy or by e mail, except that notices or requests delivered to the Lender pursuant to any of the provisions of Article II shall not be effective until received
by the Lender. All notices, financial information, or other business records sent by either party to this Agreement may be transmitted, sent, or otherwise communicated via such medium as the sending party may deem appropriate and commercially
reasonable; provided, however, that the



51



---

risk that the confidentiality or privacy of such notices, financial information, or other business records sent by either party may be compromised shall be
borne exclusively by the Borrower. All requests for an accounting under Section 9-210 of the UCC (i) shall be made in a writing signed by a Person authorized under Section 2.2(b), (ii) shall be personally delivered, sent by
registered or certified mail, return receipt requested, or by overnight courier of national reputation, (iii) shall be deemed to be sent when received by the Lender and (iv) shall otherwise comply with the requirements of
Section 9-210. The Borrower requests that the Lender respond to all such requests which on their face appear to come from an authorized individual and releases the Lender from any liability for so responding. The Borrower shall pay the Lender
the maximum amount allowed by law for responding to such requests.

Section 8.4 Further Documents. The Borrower will from time
to time execute, deliver, endorse and authorize the filing of any and all instruments, documents, conveyances, assignments, security agreements, financing statements, control agreements and other agreements and writings that the Lender may
reasonably request in order to secure, protect, perfect or enforce the Security Interest or the Lenders rights under the Loan Documents (but any failure to request or assure that the Borrower executes, delivers, endorses or authorizes the
filing of any such item shall not affect or impair the validity, sufficiency or enforceability of the Loan Documents and the Security Interest, regardless of whether any such item was or was not executed, delivered or endorsed in a similar context
or on a prior occasion).

Section 8.5 Costs and Expenses. The Borrower shall pay on demand all costs and expenses, including
reasonable attorneys fees, incurred by the Lender in connection with the Indebtedness, this Agreement, the Loan Documents, any Letter of Credit and any other document or agreement related hereto or thereto, and the transactions contemplated
hereby, including all such costs, expenses and fees incurred in connection with the negotiation, preparation, execution, amendment, administration, performance, collection and enforcement of the Indebtedness and all such documents and agreements and
the creation, perfection, protection, satisfaction, foreclosure or enforcement of the Security Interest.

Section 8.6
Indemnity. In addition to the payment of expenses pursuant to Section 8.5, the Borrower shall indemnify, defend and hold harmless the Lender, and any of its participants, parent corporations, subsidiary corporations, affiliated
corporations, successor corporations, and all present and future officers, directors, employees, attorneys and agents of the foregoing (the Indemnitees) from and against any of the following (collectively, Indemnified
Liabilities):

(i) Any and all transfer taxes, documentary taxes, assessments or charges made by any governmental
authority by reason of the execution and delivery of the Loan Documents or the making of the Advances;

(ii) Any claims,
loss or damage to which any Indemnitee may be subjected if any representation or warranty contained in Section 5.14 proves to be incorrect in any respect or as a result of any violation of the covenant contained in Section 6.12(b); and



52



---

(iii) Any and all other liabilities, losses, damages, penalties, judgments, suits,
claims, costs and expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel) in connection with the foregoing and any other investigative, administrative or judicial proceedings, whether or not such
Indemnitee shall be designated a party thereto, which may be imposed on, incurred by or asserted against any such Indemnitee, in any manner related to or arising out of or in connection with the making of the Advances and the Loan Documents or the
use or intended use of the proceeds of the Advances. Notwithstanding the foregoing, the Borrower shall not be obligated to indemnify any Indemnitee for any Indemnified Liability caused by the gross negligence or willful misconduct of such
Indemnitee.

If any investigative, judicial or administrative proceeding arising from any of the foregoing is brought against any Indemnitee, upon such
Indemnitees request, the Borrower, or counsel designated by the Borrower and satisfactory to the Indemnitee, will resist and defend such action, suit or proceeding to the extent and in the manner directed by the Indemnitee, at the
Borrowers sole costs and expense. Each Indemnitee will use its best efforts to cooperate in the defense of any such action, suit or proceeding. If the foregoing undertaking to indemnify, defend and hold harmless may be held to be unenforceable
because it violates any law or public policy, the Borrower shall nevertheless make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. The Borrowers
obligations under this Section 8.6 shall survive the termination of this Agreement and the discharge of the Borrowers other obligations hereunder.

Section 8.7 Participants. The Lender and its participants, if any, are not partners or joint venturers, and the Lender shall not have any liability or responsibility for any obligation, act or omission of
any of its participants; provided that each such participant has a net worth of at least $20,000,000 at the time it becomes a participant. All rights and powers specifically conferred upon the Lender may be transferred or delegated to any of the
Lenders participants, successors or assigns.

Section 8.8 Execution in Counterparts; Telefacsimile Execution. This
Agreement and other Loan Documents may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same
instrument. Delivery of an executed counterpart of this Agreement by telefacsimile shall be equally as effective as delivery of an original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by
telefacsimile also shall deliver an original executed counterpart of this Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement.

Section 8.9 Retention of Borrowers Records. The Lender shall have no obligation to maintain any electronic records or any documents,
schedules, invoices, agings, or other papers delivered to the Lender by the Borrower or in connection with the Loan Documents for more than 30 days after receipt by the Lender. If there is a special need to retain specific records, the Borrower must
inform the Lender of its need to retain those records with particularity, which must be delivered in accordance with the notice provisions of Section 8.3 within 30 days of the Lender taking control of same.

Section 8.10 Binding Effect; Assignment; Complete Agreement; Sharing Information. The Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights thereunder or any interest therein without
the Lenders prior written consent. To the extent permitted by law, the Borrower waives and will not assert against any assignee any claims, defenses or set-offs which the Borrower could assert against the Lender. This Agreement shall also bind
all Persons who become a party to this Agreement as a borrower. This Agreement, together with the Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and supersedes all prior agreements,
written or oral, on the subject matter hereof. To the extent that any provision of this Agreement contradicts other provisions of the Loan Documents, this Agreement shall control. The Lender shall in good faith hold in confidence all information,
memoranda, or extracts furnished to the Lender by the Borrower hereunder or in connection with the negotiation hereof; provided that the Lender may disclose such information (i) to its Affiliates, accountants or counsel; (ii) to any
regulatory agency having the authority to examine the Lender, as required by any legal or governmental process or otherwise by law, (ii) to any participant and its accountants or counsel, and (iv) to the extent that such information shall
be publicly available or shall have been known to the Lender independently of any disclosure by the Borrower hereunder or in connection herewith.

Section 8.11 Severability of Provisions. Any provision of this Agreement which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining
provisions hereof.

Section 8.12 Headings. Article, Section and subsection headings in this Agreement are included herein for
convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

Section 8.13 Governing Law;
Jurisdiction, Venue; Waiver of Jury Trial. The Loan Documents shall be governed by and construed in accordance with the substantive laws (other than conflict laws) of the State of Texas. The parties hereto hereby (i) consent to the personal
jurisdiction of the state and federal courts located in the State of Texas in connection with any controversy related to this Agreement; (ii) waive any argument that venue in any such forum is not convenient; (iii) agree that any
litigation initiated by the Lender or the Borrower in connection with this Agreement or the other Loan Documents may be venued in either the state or federal courts located in the City of Plano, County of Collin, Texas; and (iv) agree that a
final judgment in any such suit, 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.

THE BORROWER AND THE LENDER WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION AT LAW OR IN EQUITY OR IN ANY OTHER PROCEEDING BASED ON OR PERTAINING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT.
