Each request that conforms to the terms of this Agreement shall be effective upon receipt by Lender and shall be confirmed in writing by Borrower if Lender so requests by any Officer or designated agent identified in Section 2.2(b) or Person reasonably believed by 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 Rate Advances shall be in multiples of $100,000, with a minimum conversion amount of at least $1,000,000.

(b) Procedures at End of an Interest Period. Unless Borrower requests a new LIBOR Rate Advance in accordance with the procedures set forth below, or prepays the principal of an outstanding LIBOR Rate Advance at the expiration of an Interest Period, Lender shall automatically and without request of Borrower convert each LIBOR Rate Advance to a Floating Rate Advance on the last day of the relevant Interest Period. So long as no Default exists and no Notice of Non-Renewal has been given, Borrower may cause all or any part of any maturing LIBOR Rate Advance to be renewed as a new LIBOR Rate Advance by requesting that Lender continue the maturing Advance as a LIBOR Rate 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 Borrower upon Lender’s request by any Officer or designated agent identified in Section 2.2(b), which confirmation shall be effective upon receipt by Lender, and which shall specify the amount of the expiring LIBOR Rate 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 Rate Advance shall be in multiples of $100,000, with a minimum Advance of at least $1,000,000.

(c) Setting and Notice of Rates. Lender shall, with respect to any request for a LIBOR Rate Advance under Section 2.2 or a conversion or renewal of a LIBOR Rate Advance under this Section 2.3, provide Borrower with a LIBOR quote for each Interest Period identified by Borrower on the Business Day on which the request was made, if the request is received by Lender prior to the Cut-off Time, or for requests received by Lender after the Cut-off Time, on the next Business Day or on the Business Day on which Borrower has requested that the LIBOR Rate Advance be made effective. If 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 Lender of the applicable LIBOR for the LIBOR Rate Advance.

(d) Taxes and Regulatory Costs. Borrower shall pay 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 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 Borrower hereunder, any reasonable allocation made by Lender among its operations shall be conclusive and binding upon Borrower.

Section 2.4 Letters of Credit.

(a) Lender agrees, subject to the terms and conditions of this Agreement, to issue, at any time after the Funding Date and before the Termination Date, one or more irrevocable standby letters of credit (each, a “Letter of Credit”) for Borrower’s account. 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 Borrower to Lender, which must be completed in a manner satisfactory to 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 (1) 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 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 Borrower is unable, because a Default Period exists or for any other reason, to obtain a Revolving Advance to pay the Obligation of Reimbursement, Borrower shall pay to 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 full at the Default Rate. Notwithstanding Borrower’s inability to obtain a Revolving Advance for any reason, 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 a Credit Facility is terminated for any reason while any Letter of Credit is outstanding, Borrower shall thereupon pay 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 Borrower fails to promptly make any such payment in the amount required under this Agreement, then Lender may make a Revolving Advance against a 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 Lender or with a financial institution acceptable to Lender. Any interest earned on amounts deposited in the Special Account shall be credited to the Special Account. Lender may apply amounts on deposit in the Special Account at any time or from time to time to the Obligations in Lender’s sole discretion. Borrower may not withdraw any amounts on deposit in the Special Account as long as Lender maintains a security interest therein. Lender agrees to transfer any balance in the Special Account to Borrower when the Obligations have been paid in full, the Commitment has been terminated and all Letters of Credit have either expired or been terminated.

Page 24

Section 2.6 Equipment Term Advance.

(a) Lender agrees, subject to the terms and conditions of this Agreement, to make a single advance to Borrower on the Funding Date (the “Equipment Term Advance”) in an amount not exceeding the least of (i) $9,700,000, (ii) 70% of the Net Orderly Liquidation Value, or (iii) 80% of the Net Forced Liquidation Value, as that amount is determined by an independent appraisal acceptable to Lender in its sole discretion, of the Eligible Equipment. Borrower’s obligation to pay the Equipment Term Advance shall be evidenced by the Equipment 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, Lender shall deposit the proceeds of the requested Equipment Term Advance by crediting the same to Borrower’s demand deposit account specified in Section 2.2(b) unless Lender and Borrower shall agree in writing to another manner of disbursement. Upon Lender’s request, Borrower shall promptly confirm each telephonic request for the Equipment Term Advance by executing and delivering an appropriate confirmation certificate to Lender. Borrower shall be obligated to repay the Equipment Term Advance notwithstanding 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 an Equipment Term Advance, whether written or telephonic, shall be deemed to be a representation by Borrower, upon which Lender may rely, that Borrower is in compliance with the conditions set forth in Article IV as of the time of the request.

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

(a) Beginning on March 31, 2006, and on the last day of each month thereafter, in equal monthly installments in an amount sufficient to fully amortize the principal balance of the Equipment Term Note over an assumed term ending on the Assumed Maturity Date.

(b) If Lender at any time obtains an appraisal of the Equipment as permitted under Section 6.9(d) herein, and the appraisal shows the aggregate outstanding principal balance of the Equipment Term Note to exceed the lesser of (i) 70% of the Net Orderly Liquidation Value, or (ii) 80% of the Net Forced Liquidation Value, of the then Eligible Equipment, then Borrower, upon demand by Lender, shall immediately prepay the Equipment Term Note in the amount of such excess, together with any prepayment fee and other fees owed pursuant to Sections 2.9(f) and (g).

Page 25

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

(d) On the earlier of the Termination Date or the Assumed Maturity Date, the entire unpaid principal balance of the Equipment Term Note, and all unpaid interest accrued thereon, shall in any event be immediately due and payable without notice or demand therefor.

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

(a) Interest. Except as provided in Section 2.3, Section 2.8(b) and Section 2.8(e), the principal amount of each Advance shall bear interest at the Floating Rate.

(b) Default Interest Rate. At any time during any Default Period or following the Termination Date, in Lender’s sole discretion and without waiving any of its other rights or remedies, the principal of the Notes shall bear interest at the Default Rate or such lesser rate as Lender may determine, effective as of the first day of any Default Period begins through the last day of such Default Period, or any shorter time period that Lender may determine. The decision of 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 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.

(c) Application of Payments. Payments shall be applied to the Obligations on the Business Day of receipt by Lender in 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 Lender receives the payment, and continuing through the end of the first Business Day following receipt of the payment.

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

(e) Usury. In any event no rate change shall be put into effect that 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 Borrower and 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 Borrower and Lender. This provision shall never be superseded or waived and shall control every other provision of the Loan Documents and all agreements between Borrower and Lender, or their respective successors and assigns. Unless preempted by federal law or as permitted under the sentence immediately following this sentence, the Floating Rate, the LIBOR Rate or the Default Rate, as applicable, from time to time in effect under this Agreement may not exceed the “weekly ceiling” from time to time in effect under Chapter 303 of the Texas Finance Code (Vernon’s Texas Code Annotated), as amended from time to time (the “Texas Finance Code”). If the applicable state or federal law is amended in the future to allow a greater rate of interest to be charged under this Agreement than is presently allowed by applicable state or federal law, then the limitation of interest hereunder shall be increased to the maximum rate of interest allowed by applicable state or federal law as amended, which increase shall be effective hereunder on the effective date of such amendment, and all interest charges owing to Lender by reason thereof shall be payable in accordance with Section 2.8 hereof.

Page 26

Section 2.9 Fees.

(a) Closing Fee. Borrower shall pay Lender a fully earned and non-refundable closing fee of $50,000, due and payable upon the execution of this Agreement.

(b) Unused Line Fee. For the purposes of this Section 2.9(b), “Unused Amount” means the Maximum Line Amount reduced by outstanding Revolving Advances plus the L/C Amount. Borrower agrees to pay to Lender an unused line fee at the applicable Unused Line Fee Rate 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.

(c) Collateral Exam Fees. Borrower shall pay Lender fees in connection with any collateral exams, audits or inspections (including all exams occurring before the date of this Agreement) conducted by or on behalf of Lender of any Collateral or Borrower’s operations or business at the rates established from time to time by Lender as its collateral exam fees (which fees are currently $106.25 per hour per collateral examiner), together with all actual out-of-pocket costs and expenses incurred in conducting any such collateral examination or inspection.

(d) Letter of Credit Fees. Borrower shall pay to Lender a fee with respect to each Letter of Credit, if any, accruing on a daily basis and computed at an annual rate of two and 75/100ths percent (2.75%) of the aggregate amount that may then be drawn, assuming compliance with all conditions for drawing (the “Aggregate Face Amount”), from and including the date of issuance of such Letter of Credit until such date as such Letter of Credit shall terminate by its terms or be returned to Lender, due and payable monthly in arrears on the first day of each month and on the date that the Letter of Credit shall terminate by its terms or be returned to Lender; provided, however, effective as of the first day any Default Period begins through the last day of such Default Period, or any shorter time period that Lender may determine, in Lender’s sole discretion and without waiving any of its other rights and remedies, such fee shall increase to five and 75/100ths percent (5.75%) of the Aggregate Face Amount. The foregoing fee shall be in addition to any and all fees, commissions and charges imposed by Lender with respect to or in connection with such Letter of Credit.

Page 27

(e) Letter of Credit Administrative Fees. Borrower shall pay all administrative fees charged by Lender, upon Lender’s request, 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.

(f) Termination and Maximum Facility Amount Reduction Fees. If (i) Lender terminates a Credit Facility during a Default Period, or (ii) Borrower terminates or reduces a Credit Facility on a date before the Maturity Date (other than by, with respect to the Equipment Term Note, making the required principal payments under Section 2.7(a) of this Agreement), then Borrower shall pay Lender as liquidated damages (and not as a penalty), a termination fee in an amount equal to the reduction of the Maximum Facility Amount as reduced by the principal payments actually made by Borrower on the Equipment Term Note pursuant to Section 2.7(a) (for the purpose of calculating the reduction with respect with to the revolving facility component of the Maximum Facility Amount, such reduction shall equal the average of the outstanding principal balance of the Revolving Note measured on the last day of each of preceding twelve calendar months) multiplied by the applicable percentage determined as follows: (A) three percent (3%) if the termination or reduction occurs on or before the first anniversary of the Funding Date; (B) two percent (2%) 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 (1%) if the termination or reduction occurs after the second anniversary of the Funding Date, but before the Maturity Date.

(g) Contracted Funds Breakage Fees. In addition to payment of the fees under Section 2.9(f), Borrower shall pay to Lender the following amount in connection with any prepayment of the principal amount of the Notes, whether such prepayment is voluntary or by acceleration:

(i) If the principal amount of any LIBOR Rate Advance is prepaid, Borrower shall pay to 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 LIBOR Rate applicable to such amount had it remained outstanding until the last day of the applicable Interest Period.

(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 in a principal amount equal to the amount prepaid.

Page 28

(C)

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

(ii) Borrower acknowledges that a prepayment may result in Lender incurring additional costs, expenses or liabilities, and that it is difficult to ascertain the full extent of such costs, expenses or liabilities. Borrower therefore agrees to pay the above-described prepayment fee and agrees that said prepayment fee represents a reasonable estimate of the prepayment costs, expenses or liabilities of Lender.

(h) Waiver of Termination and Prepayment Fees. Borrower will be excused from the payment of termination and prepayment fees otherwise due under Section 2.9(f) and Section 2.9(g) if such termination or prepayment is made because of refinancing through another division of Lender that closes more than eighteen months (18) after the Funding Date.

(i) Overadvance Fees. Borrower shall pay an Overadvance fee in the amount of $500 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 Lender. The acceptance of payment of an Overadvance fee by Lender shall not be deemed to constitute either consent to the Overadvance or a waiver of the resulting Event of Default, unless Lender specifically consents to the Overadvance in writing and waives the Event of Default on whatever conditions Lender deems appropriate.

(j) Other Fees and Charges; Payment of Fees. Lender may from time to time impose additional fees and charges as consideration for Revolving 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 Lender, and fees and charges for the late delivery of reports, which may be assessed in 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 each Floating Rate Advance shall be due and payable in arrears 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. Interest accruing on each LIBOR Rate 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.

Page 29

(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) Borrower shall instruct all account debtors to pay all Accounts directly to the Lockbox. If, notwithstanding such instructions, Borrower receives any payments on Accounts, Borrower shall deposit such payments into the Collateral Account. Borrower shall also deposit all other cash proceeds of Collateral regardless of source or nature directly into the Collateral Account. Until so deposited, Borrower shall hold all such payments and cash proceeds in trust for and as the property of 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 Obligations.

(ii) All items deposited in the Collateral Account shall be subject to final payment. If any such item is returned uncollected, Borrower will immediately pay 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 Borrower’s commercial account or other account. Borrower shall be liable as an endorser on all items deposited in the Collateral Account, whether or not in fact endorsed by Borrower.

(b) Sweep of Funds. 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 (at Borrower’s expense) to Lender’s general account for payment of the Obligations, after giving effect to a collection period of at least two Business Days, in addition to any period imposed after such transfer pursuant to Section 2.8(c). Amounts deposited in the Collateral Account shall not be subject to withdrawal by Borrower, except after payment in full and discharge of all Obligations.

Section 2.12 Term. This Agreement and the other Loan Documents shall become effective as of the Funding Date and shall continue in full force and effect until and including March 3, 2010 (the “Renewal Date”); however, (i) if the Notice of Non-Renewal (as defined below) has not been given, or this Agreement has not been otherwise terminated, and (ii) the maturity date of each Senior Subordinated Promissory Note and all other terms of those notes (including, without limitation, the subordination provisions) have been extended in writing by BNC and Subordinated Creditor for an additional year, this Agreement, the other Loan Documents and all Liens and Security Interests relating thereto shall automatically renew, without the necessity of any further documentation or action, on a year to year basis thereafter and otherwise on the same terms and conditions set forth in this Agreement and the other Loan Documents. Lender or Borrower may terminate this Agreement and the other Loan Documents (other than those provisions that expressly survive the termination of this Agreement or any Loan Document, which provisions shall survive in accordance with their respective terms) effective on the Renewal Date or on the anniversary of the Renewal Date by giving to the other party at least 30 days’ prior written notice, or such additional notice as may be required under Section 2.13 (the “Notice of Non-Renewal”), provided this Agreement and all other Loan Documents must be terminated simultaneously. Any notice requesting termination of this Agreement shall constitute a request to terminate both this Agreement and the other Loan Documents.

Page 30

Section 2.13 Voluntary Prepayment; Reduction of the Maximum Facility Amount; Termination of a Credit Facility by Borrower. Except as otherwise provided in this Agreement, Borrower may prepay the Advances in whole at any time or from time to time in part. Borrower may terminate a Credit Facility or reduce the Maximum Facility Amount at any time if it (i) gives Lender at least 90 days advance written notice prior to the proposed Termination Date, and (ii) pays Lender applicable termination and Maximum Facility Amount reduction fees in accordance with Section 2.9(f) and the contracted funds breakage fees of Section 2.9(g). Any reduction in the Maximum Line Amount shall be in multiples of $100,000, and with a minimum reduction of at least $500,000. If Borrower terminates a Credit Facility or reduces the Maximum Line Amount to zero, all Obligations shall be immediately due and payable, and if Borrower gives 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 Lender actually receives such written notice. If Borrower does not wish Lender to consider renewal of the Credit Facility on the next Maturity Date, then Borrower shall give Lender at least 90 days written notice before the Maturity Date that it will not be requesting renewal. If Borrower fails to give 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 Lender actually receives such written notice.

Section 2.14 Mandatory Prepayment. Without notice or demand, if Overadvance exists, Borrower shall immediately (i) first, prepay the Revolving Advances to the extent necessary to eliminate the Overadvance; and (ii) if prepayment in full of the Revolving Advances is insufficient to eliminate the Overadvance, pay to Lender in immediately available funds for deposit in the Special Account an amount equal to the remaining excess. Any payment received by Lender under this Section 2.14 or under Section 2.13 may be applied to the Obligations, in such order and in such amounts as Lender in its sole discretion may determine from time to time.

Section 2.15 Revolving Advances to Pay Obligations. Notwithstanding the terms of Section 2.1, Lender may, in its discretion at any time or from time to time, without Borrower’s request and even if the conditions set forth in Article IV would not be satisfied, make a Revolving Advance in an amount equal to the portion of the Obligations from time to time due and payable, and may deliver the proceeds of any such Revolving Advance to any affiliate of Lender in satisfaction of any ▇▇▇▇▇ Fargo Bank Affiliate Obligations.

Section 2.16 Use of Proceeds. Borrower shall use the proceeds of Advances for the purposes (in the following order) of repaying Borrower’s existing lenders, repurchasing certain capital stock and warrants in BNC pursuant to the Securities Repurchase Agreement, funding ordinary working capital needs, paying fees and expenses incurred in connection with the transaction contemplated by this Agreement, and consummating the acquisition and merger transactions contemplated by the Transaction Agreement.

Page 31

Section 2.17 Liability Records. Lender may maintain from time to time, at its discretion, records as to the Obligations. All entries made on any such record shall be presumed correct until Borrower establishes the contrary. Upon Lender’s demand, Borrower will admit and certify in writing the exact principal balance of the Obligations that Borrower then asserts to be outstanding. Any billing statement or accounting rendered by Lender shall be conclusive and fully binding on Borrower unless Borrower gives Lender specific written notice of exception within 30 days after receipt.

ARTICLE III

SECURITY INTEREST; OCCUPANCY; SETOFF

Section 3.1 Grant of Security Interest. Borrower hereby pledges, assigns and grants to Lender for the benefit of itself and as agent for any affiliate of Lender that may provide credit or services to Borrower that constitute ▇▇▇▇▇ Fargo Bank Affiliate Obligations, a lien and security interest (collectively referred to as the “Security Interest”) in the Collateral, as security for the payment and performance of the Obligations. Upon request by Lender, Borrower will grant Lender, for the benefit of itself and as agent for any affiliate of Lender that may provide credit or services to Borrower that constitute ▇▇▇▇▇ Fargo Bank Affiliate Obligations, a security interest in all commercial tort claims that Borrower may have against any Person.

Section 3.2 Notification of Account Debtors and Other Obligors. Lender may at any time (after the occurrence and during the continuance of a Default) notify any account debtor or other Person obligated to pay the amount due that such right to payment has been assigned or transferred to Lender for security and shall be paid directly to Lender. Borrower will join in giving such notice if Lender so requests. At any time after Borrower or Lender gives such notice to an account debtor or other obligor, Lender may, but need not, in Lender’s name or in Borrower’s name, demand, ▇▇▇ 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. Lender may, in Lender’s name or in Borrower’s name, as Borrower’s agent and attorney-in-fact, notify the United States Postal Service to change the address for delivery of Borrower’s mail to any address designated by Lender, otherwise intercept Borrower’s mail, and receive, open and dispose of Borrower’s mail, applying all Collateral as permitted under this Agreement and holding all other mail for Borrower’s account or forwarding such mail to Borrower’s last known address.

Section 3.3 Assignment of Insurance. As additional security for the payment and performance of the Obligations, Borrower hereby assigns to 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 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 Borrower hereby directs the issuer of any such policy to pay all such monies directly to Lender. At any time a Default Period exists or the time period for taking any action described in this sentence will expire or lapse within thirty (30) days and Borrower has not taken such action before such time, Lender may (but need not), in Lender’s name or in 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. 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 Lender to be applied, at the option of Lender, either to the prepayment of the Obligations or shall be disbursed to Borrower under staged payment terms reasonably satisfactory to 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.

Page 32

Section 3.4 Occupancy.

(a) Borrower hereby irrevocably grants to Lender the right to non-exclusive possession of the Premises at any time during a Default Period without notice or consent.

(b) 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 Lender may in good ▇▇▇▇▇ ▇▇▇▇ to be related or incidental purposes.

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

(d) 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 Lender does pay or account for any rent or other compensation for the possession, occupancy or use of any of the Premises, Borrower shall reimburse Lender promptly for the full amount thereof. In addition, Borrower will pay, or reimburse Lender for, all taxes, fees, duties, impositions, charges and expenses at any time incurred by or imposed upon Lender by reason of the execution, delivery, existence, recordation, performance or enforcement of this Agreement or the provisions of this Section 3.4.

Section 3.5 License. Without limiting the generality of any other Security Document, Borrower hereby grants to Lender a non-exclusive, worldwide and royalty-free license to use or otherwise exploit all Intellectual Property Rights of Borrower for the purpose of: (a) completing the manufacture of any in-process materials during any Default Period so that such materials become saleable Inventory, all in accordance with the same quality standards previously adopted by Borrower for its own manufacturing and subject to Borrower’s reasonable exercise of quality control; and (b) selling, leasing or otherwise disposing of any or all Collateral during any Default Period.

Section 3.6 Financing Statement. Borrower authorizes Lender to file from time to time, such financing statements against collateral described as “all personal property” or “all assets” or describing specific items of collateral including commercial tort claims as Lender deems necessary or useful to perfect the Security Interest. All financing statements filed before the date hereof to perfect the Security Interest were authorized by Borrower and are hereby re-authorized. A carbon, photographic or other reproduction of this Agreement or of any financing statements signed by Borrower is sufficient as a financing statement and may be filed as a financing statement in any state to perfect the security interests granted hereby. For this purpose, Borrower represents and warrants that the following information is true and correct:

Lender may at any time or from time to time after the occurrence and during the continuance of a Default Period, at its sole discretion and without demand and without notice to anyone, setoff any liability owed to Borrower by Lender, whether or not due, against any Obligation, then due. In addition, each other Person holding a participating interest in any Obligations shall have the right to appropriate or setoff any deposit or other liability then owed by such Person to 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 Borrower the amount of such participating interest.

This Agreement does not contemplate a sale of accounts, contract rights or chattel paper, and, as provided by law, Borrower is entitled to any surplus and shall remain liable for any deficiency. 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 Lender need not otherwise preserve, protect, insure or care for any Collateral. Lender shall not be obligated to preserve any rights 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.

Section 6.19 Sale and Leaseback. BNC and Borrower will not, and will not permit any other Credit Party to, enter into any arrangement, directly or indirectly, with any other Person whereby a Credit Party shall sell or transfer any real or personal property, whether now owned or hereafter acquired, and then or thereafter rent or lease as lessee such property or any part thereof or any other property which a Credit Party intends to use for substantially the same purpose or purposes as the property being sold or transferred.

Section 6.20 Restrictions on Nature of Business. BNC and Borrower will not, and will not permit any other Credit Party to, engage in any line of business materially different from that presently engaged in by a Credit Party and will not purchase, lease or otherwise acquire assets not related to its business. No Inactive Subsidiary may commence business operations without Lender’s express, prior and written consent.

Section 6.21 Accounting. BNC and Borrower will not, and will not permit any other Credit Party to, adopt any material change in accounting principles other than as required by GAAP.

Section 6.22 Discounts. After notice from Lender given during the existence and continuance of a Default and then only, Borrower will not grant any discount, credit or allowance to any customer of Borrower or accept any return of goods sold. Borrower will not at any time modify, amend, subordinate, cancel or terminate the obligation of any account debtor or other obligor of Borrower, except in the normal course of business and then only if such action is dictated by commercial considerations in Borrower’s good faith judgment and such action need not be reported pursuant to Section 6.1(i).

Unless disclosed to Lender pursuant to Section 5.12, neither any Credit Party nor any ERISA Affiliate will (i) adopt, create, assume or become a party to any Pension Plan, (ii) incur any obligation to contribute to any Multiemployer Plan, (iii) incur any obligation to provide post-retirement medical or insurance benefits with respect to employees or former employees (other than benefits required by law) or (iv) amend any Plan in a manner that would materially increase its funding obligations.

Section 6.24 Place of Business; Name. BNC and Borrower will not, and will not permit any other Credit Party to, transfer its chief executive office or principal place of business to a location outside the state where its chief executive office or principal place of business is presently located, or move, relocate, close or sell any business location. BNC and Borrower will not permit any tangible Collateral or any records pertaining to the Collateral to be located in any state or area in which, in the event of such location, a financing statement covering such Collateral would be required to be, but has not in fact been, filed in order to perfect the Security Interest. BNC and Borrower will not, and will not permit any other Credit Party to, change its name or jurisdiction of organization.

Section 6.25 Constituent Documents. BNC and Borrower will not, and will not permit any other Credit Party to, amend its Constituent Documents if such amendment would be adverse in any way to Lender or would affect Lender’s Lien or the classification of the Equity Interests as “securities” under Article 8 of the UCC.

Section 6.26 Senior Subordinated Loan Documents, Securities Repurchase Agreement and HWC Transaction Documents. BNC and Borrower shall immediately deliver to Lender a true, correct and complete copy of any notice it or any Subsidiary receives in connection with the Senior Subordinated Loans, the Securities Repurchase Agreement or the HWC Transaction Documents, including notices of default, and BNC and Borrower shall immediately notify Lender in writing of the name and address of any subsequent holder of a Senior Subordinated Loan upon learning of a sale, assignment or other transfer of any Senior Subordinated Loan. BNC and Borrower will (i) timely comply with, and will cause its Subsidiaries to timely comply with, all of their respective obligations relating to the Senior Subordinated Loans, subject to the terms of the Subordination Agreement, (ii) timely enforce all of its material rights and remedies under the Senior Subordinated Loan Documents, the Securities Repurchase Agreement and the HWC Transaction Documents in accordance with their respective terms, (iii) not, and will not permit any of its Subsidiaries to, amend, waive or terminate any provision of the Senior Subordinated Loan Documents, the Securities Repurchase Agreement or the HWC Transaction Documents without the express written consent of Lender, and (iv) not make any Distribution under the Senior Subordinated Loan Documents or the HWC Transaction Documents, except in each case Permitted Subordinated Debt Payments made in accordance with the terms of the Senior Subordinated Promissory Notes.

Section 6.27 Transactions with Affiliates. BNC and Borrower may not, and will not permit any of the Credit Parties to, enter into or consummate any transaction of any kind with any of its Affiliates other than: (a) salary, bonus and other compensation and employment arrangements as permitted under Section 6.8, (b) as set forth on Schedule 5.24, or (c) other transactions and payments under and pursuant to written agreements entered into by and between a Credit Party and one or more of its Affiliates that reflect and constitute transactions and payments on overall terms at least as favorable to the Credit Party as would be the case in an arm’s length transaction between unrelated parties of equal bargaining power; however, except as expressly permitted under this Agreement, no Credit Party may enter into or consummate any transaction or agreement pursuant to which it becomes a party to any mortgage, note, indenture or guarantee evidencing any indebtedness of any of its Affiliates or otherwise to become responsible or liable, as a guarantor, surety or otherwise, pursuant to an agreement for any indebtedness of any such Affiliate.

Page 58

Section 6.28 Snubbing Units. Borrower shall at all times have access to the Snubbing Units wherever located pursuant to a Snubbing Unit Agreement, and Borrower shall have the right to enter on property where a Snubbing Unit is located and to remove such Snubbing Unit therefrom without interference from, or imposition of any Lien on such Snubbing Unit by, any owner, landlord, tenant or other Person with an interest in such property. No Snubbing Unit that constitutes Eligible Equipment may ever be located outside the control and jurisdiction of the United States of America. BNC and Borrower shall ensure that each Snubbing Unit never (a) constitutes a fixture, or immoveable property, as the case may be, under the laws of any jurisdiction in which a Snubbing Unit may be located, (b) constitutes part of a “vessel”, as defined under applicable maritime law, (c) becomes subject to, or is being utilized pursuant to, a maritime contract, (d) constitutes a “motor vehicle” under any statute, law, regulation or rule of any jurisdiction in which any Snubbing Unit is located, and (e) is certificated as a motor vehicle under the laws of any jurisdiction. Each Snubbing Unit that Lender has financed under the Equipment Term Advance shall at all times constitute Eligible Equipment. Borrower will use commercially reasonable efforts to timely enforce and realize upon all rights and remedies it may have from time to time under applicable law, including all Lien rights under Chapter 56 of the Texas Property Code, as amended and in effect, or other analogous rights under the laws of the jurisdiction where Borrower has provided materials and services pursuant to a Snubbing Unit Agreement.

Section 6.29 Performance by Lender. If BNC or Borrower, or both of them, at any time fails to perform or observe any of the foregoing covenants contained in this Article VI or elsewhere herein, and if such failure shall continue for a period of ten calendar days after Lender gives BNC or Borrower written notice thereof (or in the case of the agreements contained in Section 6.11 and Section 6.13, immediately upon the occurrence of such failure, without notice or lapse of time), Lender may, but need not, perform or observe such covenant on behalf and in the name, place and stead of Borrower (or, at Lender’s option, in Lender’s name) and may, but need not, take any and all other actions which Lender may reasonably deem necessary to cure or correct such failure (including the payment of taxes, the satisfaction of Liens, the performance of obligations owed to account debtors or other obligors, the procurement and maintenance of insurance, the execution of assignments, security agreements and financing statements, and the endorsement of instruments); and Borrower shall thereupon pay to Lender on demand the amount of all monies expended and all costs and expenses (including reasonable attorneys’ fees and legal expenses) incurred by Lender in connection with or as a result of the performance or observance of such agreements or the taking of such action by Lender, together with interest thereon from the date expended or incurred at the Default Rate. To facilitate Lender’s performance or observance of such covenants of BNC and Borrower, BNC and Borrower hereby irrevocably appoint Lender, or Lender’s delegate, acting alone, as BNC’s and Borrower’s attorney in fact (which appointment is coupled with an interest) with the right (but not the duty) from time to time to create, prepare, complete, execute, deliver, endorse or file in the name and on behalf of BNC and Borrower, or both of them, any and all instruments, documents, assignments, security agreements, financing statements, applications for insurance and other agreements and writings required to be obtained, executed, delivered or endorsed by BNC and Borrower hereunder.

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

(d) 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 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, Borrower will on demand assemble the Collateral and make it available to Lender at a place to be designated by Lender which is reasonably convenient to both parties;

(e) Lender may make demand upon Borrower and, immediately upon such demand, Borrower will pay to 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, notwithstanding that the conditions for drawing thereunder may not yet have been satisfied;

Section 7.3 Certain Notices.

ARTICLE VIII

MISCELLANEOUS

Section 8.1 No Waiver; Cumulative Remedies; Compliance with Laws; No Marshaling. No failure or delay by 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. 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. Borrower consents and agrees that Lender shall be under no obligation to marshal any of Borrower’s assets or Lender’s Liens against or in payment of any or all of the Obligations.

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

Page 63

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) when deposited 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 Lender pursuant to any of the provisions of Article II shall not be effective until received by 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 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 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(a), (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 Lender and (iv) shall otherwise comply with the requirements of Section 9.210 of the UCC. Borrower requests that Lender respond to all such requests that on their face appear to come from an authorized individual and releases Lender from any liability for so responding. Borrower shall pay Lender the maximum amount allowed by law for responding to such requests.

Section 8.4 Further Documents. 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 Lender may reasonably request in order to secure, protect, perfect or enforce the Security Interest or Lender’s rights under the Loan Documents (but any failure to request or assure that 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); provided, however, Borrower shall not be required to pledge more than sixty-five percent (65%) of the voting Equity Interests of any Foreign Subsidiary, to the extent such a pledge of additional Equity Interests would result in material and adverse tax consequences to Borrower under Section 956 of the IRC as determined by Lender in its sole discretion.

Section 8.5 Costs and Expenses. Borrower shall pay on demand all costs and expenses, including reasonable attorneys’ fees, closing costs, appraisal fees, UCC search and recording fees, costs of individual and corporate credit reports, surveys, and real estate title searches, environmental assessment fees and Collateral auditing fees, incurred by Lender in connection with the Obligations, this Agreement, the Loan Documents, 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 Obligations and all such documents and agreements and the creation, perfection, protection, satisfaction, foreclosure or enforcement of the Security Interest.

Page 64

Section 8.6 Indemnity. In addition to the payment of expenses pursuant to Section 8.5, Borrower and BNC shall indemnify, defend and hold harmless Lender, and any of its participants assigns, 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 6.11(b); and

(iii) Any and all other liabilities (INCLUDING ALL STRICT 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.

If any investigative, judicial or administrative proceeding arising from any of the foregoing is brought against any Indemnitee, upon such Indemnitee’s request, Borrower and BNC, or counsel designated by Borrower and BNC 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 Borrower’s and BNC’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, Borrower and BNC shall nevertheless make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law. IT IS THE INTENTION OF BORROWER AND BNC, AND BORROWER AND BNC AGREE, THAT THE INDEMNITIES CONTAINED IN THIS AGREEMENT SHALL APPLY WITH RESPECT TO THE INDEMNIFIED MATTERS, WHICH MAY BE IN WHOLE OR IN PART CAUSED BY OR MAY ARISE OUT OF THE SOLE, CONTRIBUTORY OR COMPARATIVE NEGLIGENCE OR ANY STRICT LIABILITY OF ANY INDEMNITEE; HOWEVER, SUCH INDEMNITIES SHALL NOT EXTEND TO AN OTHERWISE INDEMNIFIED MATTER TO THE EXTENT THAT IT ARISES OUT OF THE INDEMNITEE’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. Borrower’s and BNC’s obligation under this Section 8.6 shall survive the termination of this Agreement and the discharge of Borrower’s and BNC’s other obligations hereunder.

Page 65

Section 8.7 Participants. Lender and its participants, if any, are not partners or joint venturers, and Lender shall not have any liability or responsibility for any obligation, act or omission of any of its participants. All rights and powers specifically conferred upon Lender may be transferred or delegated to any of 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. Lender shall have no obligation to maintain any electronic records or any documents, schedules, invoices, agings, or other papers delivered to Lender by Borrower or in connection with the Loan Documents for more than 30 days after receipt by Lender. If there is a special need to retain specific records, Borrower must inform 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 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 BNC, Borrower and Lender and their respective successors and assigns, except that BNC and Borrower shall not have the right to assign any rights thereunder or any interest therein without Lender’s prior written consent. To the extent permitted by law, BNC and Borrower waive and will not assert against any assignee any claims, defenses or set-offs that BNC or Borrower could assert against 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, AND WITHOUT LIMITING THE FOREGOING, BNC AND BORROWER AGREE THAT THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES. To the extent that any provision of this Agreement contradicts other provisions of the Loan Documents, this Agreement shall control. Without limiting Lender’s right to share information regarding BNC, Borrower and their respective Affiliates with Lender’s participants, accountants, lawyers and other advisors, Lender may share any and all information they may have in their possession regarding BNC, Borrower and their respective Affiliates, and BNC and Borrower waive any right of confidentiality they may have with respect to such sharing of information.

Section 8.13 Governing Law; Jurisdiction, Venue; Waiver of Jury Trial.

Borrower and Lender hereby agree that, except for the opt-out provisions of Section 346.004 thereof, the provisions of Chapter 346 of the Texas Finance Code (regulating certain revolving credit loans and revolving tri-party accounts) shall not apply to this Agreement or any of the other Loan Documents.
