Within the limits set forth in this SECTION 2.1, the Borrowers may borrow, prepay pursuant to SECTION 2.11, and reborrow. Section 2.2 PROCEDURES FOR REQUESTING ADVANCES. Each Borrower shall comply with the following procedures in requesting Revolving Advances: (a) TIME FOR REQUESTS. Such Borrower shall request each Advance not later than the Cut-off Time on the Business Day the Advance is to be made. Each request that conforms to the terms of this Agreement shall be effective upon receipt by the Lender, shall be in writing or by telephone or telecopy transmission, and shall be confirmed in writing by such Borrower if so requested by the Lender, by (i) an Officer of Allis Chalmers; or (ii) a person designated as such Borrower's agent by an Officer of Allis Chalmers in a writing delivered to the Lender; or (iii) a person whom the Lender reasonably believes to be an Officer of Allis Chalmers or such a designated agent. The Borrowers 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 Borrowers that the conditions set forth in SECTION 4.2 have been satisfied as of the time of the request. (b) 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 requesting Borrower's demand deposit account maintained with Wells Fargo Bank unless the Lender and such Borrower shall agree in writing to another manner of disbursement. -14- Section 2.3 LETTERS OF CREDIT. (a) The Lender agrees, subject to the terms and conditions of this Agreement, to cause Wells Fargo Bank 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 a Borrower's account by acting as such Borrower's co-applicant to Wells Fargo Bank as issuer. The Lender shall have no obligation to cause Wells Fargo Bank to issue any Letter of Credit if the face amount of the Letter of Credit to be issued would exceed the lesser of: (i) $3,000,000 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 requesting Borrower and the Lender as co-applicants to Wells Fargo Bank, which must be completed in a manner satisfactory to the Lender and Wells Fargo Bank. 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 the Termination Date in effect as of the date of issuance. (c) Any request for issuance of a Letter of Credit shall be deemed to be a representation by the requesting 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 Borrowers are unable, because a Default Period exists or for any other reason, to obtain a Revolving Advance to pay the Obligation of Reimbursement, the Borrowers 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 full at the Default Rate. Notwithstanding the Borrowers 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 2.4 SPECIAL ACCOUNT. If the Credit Facility is terminated for any reason while any Letter of Credit is outstanding, the Borrowers 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 Borrowers fail to promptly make any such payment in the amount required hereunder, then 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 maintained for the Lender by any 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 Obligations in the Lender's sole discretion. No Borrower may 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 Borrowers when the Lender is required to release its security interest in the Special Account under applicable law. -15- Section 2.5 TERM ADVANCES. (a) TERM A ADVANCES. On February 1, 2002, the Lender made a term advance to Jens in the principal amount of $4,092,396, and a real estate advance to Jens in the principal amount of $532,000 (collectively, the "Jens Term Advances"), which advances were evidenced by the Jens Term Notes. The combined outstanding principal balance of the Jens Term Notes as of November 12, 2004, was $2,838,704.54. The Lender agrees, subject to the terms and conditions of this Agreement, to make a single advance to the Borrowers on the Funding Date in the amount of $3,496,295.46 (collectively, together with the Jens Term Advances, the "Term A Advances"). The Borrowers' obligation to pay the Term A Advances shall be evidenced by the Term A Note, shall be joint and several and shall be secured by the Collateral as provided in ARTICLE III. TERM B ADVANCES. The Lender agrees, subject to the terms and conditions of this Agreement, to make advances to the Borrowers from time to time from the Funding Date to December 31, 2005 (each a "Term B Advance"). The Lender will have no obligation to make a Term B Advance if, after giving effect to such requested Term B Advance, the outstanding principal balance of the Term B Advances would exceed the lesser of the following amount reduced by the aggregate amount of the scheduled principal payments described in SECTION 2.6: (A) $6,000,000 and (B) the SUM of (Y) eighty percent (80%) of the purchase price (excluding tax, freight, and installation charges) of new Eligible Equipment purchased with proceeds of Term B Advances, AND (Z) the LESSER of (1) eighty percent (80%) of the orderly liquidation value and (2) ninety percent (90%) of the forced liquidation value of used Eligible Equipment purchased with proceeds of Term B Advances and acquired individually or in connection with asset acquisitions consented to in writing by the Lender. The Borrowers' obligation to pay the Term B Advances shall be evidenced by the Term B Note, shall be joint and several and shall be secured by the Collateral as provided in ARTICLE III. The Borrowers shall comply with the following procedures in requesting Term B Advances: The requesting Borrower shall make each request for a Term B Advance to the Lender no later than the Cut-off Time on the Business Day on which any Borrower wishes to receive a Term B Advance. Requests may be made in writing or by telephone, specifying the date of the requested Term B Advance and the amount thereof. -16- The amount of each Term B Advance shall be shall be an integral multiple of $100,000, with a minimum amount of at least $200,000. Each request shall be by an individual authorized pursuant to SECTION 2.2(a). Upon fulfillment of the applicable conditions set forth in ARTICLE IV, the Lender shall deposit the proceeds of the requested Term B Advance by crediting the same to the requesting Borrower's demand deposit account specified in SECTION 2.2(B) unless the Lender and the Borrowers shall agree in writing to another manner of disbursement. Upon the Lender's request, the requesting Borrower shall promptly confirm each telephonic request for a Term B Advance by executing and delivering an appropriate confirmation certificate to the Lender. The Borrowers shall be obligated to repay all Term B 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 Term B Advance, whether written or telephonic, shall be deemed to be a representation by the Borrowers, upon which the Lender may rely, that the Borrowers are in compliance with the conditions set forth in SECTION 4.2 as of the time of the request. Section 2.6 PAYMENT OF TERM NOTES. (a) PAYMENT OF TERM A NOTE. The outstanding principal balance of the Term A Note shall be due and payable as follows: Beginning on January 1, 2005, and on the first day of each month thereafter, in substantially equal monthly installments of $105,583.33. In addition, within seven (7) days after any Borrower receives a MATYEP Payment, in an amount equal to twenty percent (20%) of such MATYEP Payment ("Term A Scoops"), which Term A Scoops shall not exceed $1,000,000 in any twelve (12) month period commencing on December 1 of any year. In addition, if the 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 Term A Note to exceed the LESSER of eighty percent (80%) of the orderly liquidation value of Eligible Equipment (other than Equipment purchased with proceeds of Term B Advances) and ninety percent (90%) of the forced sale liquidation value of the Eligible Equipment of the Borrowers (other than Equipment purchased with proceeds of Term B Advances), then the Borrowers, within thirty (30) days of notice and demand by the Lender, shall prepay the Term A Note in the amount of such excess. -17- All prepayments of principal with respect to the Term A Note shall be applied to the most remote principal installment or installments then unpaid. On the Termination Date, the entire unpaid principal balance of the Term A Note, and all unpaid interest accrued thereon, will in any event be due and payable. (b) PAYMENT OF TERM B NOTE. The outstanding principal balance of the Term B Note shall be due and payable as follows: Beginning on January 1, 2006, in substantially equal monthly installments in an amount equal to one forty-eighth (1/48) of the outstanding principal balance of the Term B Note on December 31, 2005. In addition, after all of the Term A Advances have been paid in full, within seven (7) days after any Borrower receives a MATYEP Payment, in an amount equal to twenty percent (20%) of such MATYEP Payment ("Term B Scoops"), which Term B Scoops, together with any Term A Scoops paid during such fiscal year, shall not exceed $1,000,000 in any twelve (12) month period commencing on December 1 of any year. In addition, if the 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 Term B Note to exceed the LESSER of eighty percent (80%) of the orderly liquidation value of Eligible Equipment purchased with Term B Advances and ninety percent (90%) of the forced sale liquidation value of the Eligible Equipment purchased with Term B Advances, then the Borrowers, within thirty (30) days of notice and demand by the Lender, shall prepay the Term B Note in the amount of such excess. All prepayments of principal with respect to the Term B Note shall be applied to the most remote principal installment or installments then unpaid. On the Termination Date, the entire unpaid principal balance of the Term B Note, and all unpaid interest accrued thereon, will in any event be due and payable. Section 2.7 INTEREST; MINIMUM INTEREST CHARGE; DEFAULT INTEREST RATE; APPLICATION OF PAYMENTS; PARTICIPATIONS; USURY. (a) INTEREST. Except as provided in SECTION 2.7(c) and SECTION 2.7(f), the principal amount of each Advance shall bear interest at the Floating Rate. (b) MINIMUM INTEREST CHARGE. Notwithstanding the interest payable pursuant to Subsection (a), the Borrowers shall pay to the Lender interest and Unused Line Fees of not less than $20,000 per month (the "Minimum Interest Charge") during the term of this Agreement, and the Borrowers shall pay any deficiency between the Minimum Interest Charge and the sum of (i) the amount of interest otherwise calculated under SECTION 2.7(a) plus (ii) the amount of the Unused Line Fee, on the first day of each month and on the Termination Date. When calculating the deficiency due hereunder, if any, between the Minimum Interest Charge and the amount of interest otherwise payable under SECTION 2.7(a), the Default Rate, if applicable, shall be disregarded. -18- (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 Notes 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 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 Obligations on the Business Day of receipt by the Lender, 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 first Business Day following receipt of the payment. (e) PARTICIPATIONS. If any Person shall acquire a participation in the Advances or the Obligation of Reimbursement, each Borrower shall be obligated to the Lender to pay the full amount of all interest calculated under this SECTION 2.7 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 2.7, or otherwise elects to accept less than its prorata share of such fees, charges and other amounts due under this Agreement. (f) MAXIMUM RATE. (i) Notwithstanding the other provisions of this Agreement or of any Note regarding interest and rates of interest, it is the intent of the Lender and the Borrowers that the execution, delivery and performance of all Loan Documents, the transactions provided for therein and contemplated thereby, and all matters incidental and related thereto and arising therefrom, will comply and conform strictly with any governing law from time to time in effect, including usury laws. In furtherance thereof, the Lender and the Borrowers stipulate and agree that none of the terms and provisions contained in, or pertaining to, the Loan Documents will ever be construed to create a contract to pay for the use or forbearance or detention of money with interest at a rate or in an amount in excess of the maximum amount of interest permitted or allowed to be contracted for, charged, received, taken or reserved under said laws (the "Maximum Rate"). For purposes of each Loan Document, (x) "interest" will include the aggregate of all amounts which constitute or are deemed to constitute interest under Applicable Law, that are contracted for, chargeable, receivable (whether received or deemed to have been received), taken or reserved under each such -19- document, and (y) all computations of the Maximum Rate will be made on the basis of the actual number of days elapsed over a three hundred sixty five (365) or three hundred sixty six (366) day year, whichever is applicable. Neither the Borrowers nor any other Person will ever be required to pay unearned interest on, or with respect to any of, the Loan Documents and will never be required to pay interest on, or with respect to any of, the Loan Documents at a rate or in an amount in excess of the Maximum Rate, AND THE PROVISIONS OF THIS PARAGRAPH WILL CONTROL OVER ALL OTHER PROVISIONS OF THE LOAN DOCUMENTS. "Applicable Law" means the law of the state designated in SECTION 8.13 hereof as the state whose laws will govern this Agreement, or, if a court of competent jurisdiction determines that the law of any other jurisdiction applies to the determination of whether the rate of interest payable under this Agreement and the Notes is usurious, the law of such jurisdiction. If the effective rate or amount of interest that would otherwise be payable under the Loan Documents would exceed the Maximum Rate, or in the event the Lender or any holder of any Note or other Obligation will charge, contract for, take, reserve or receive monies that are deemed to constitute interest that would, in the absence of this provision, increase the effective rate or amount of interest payable under the Loan Documents to a rate or amount in excess of the Maximum Rate, then the principal amount of such Note or other Obligation or the amount of interest that would otherwise be payable thereunder will be payable at, or reduced to, as applicable, the Maximum Rate, and all such monies so charged, contracted for, received, taken or reserved that are deemed to constitute interest in excess of the Maximum Rate will be immediately credited to such Note or Obligation or, if such Note or Obligation has been paid in full, returned or credited to the account of the Borrowers upon such determination, and, in any event, the Lender will not be subject to any penalties provided by any laws for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum Rate. All amounts paid or agreed to be paid in connection with any Note or other Obligation which would under Applicable Law be deemed "interest" or if not so deemed, would be deemed an amount that would be included in the calculation of the Maximum Rate will, to the extent necessary to prevent such amount from exceeding the Maximum Rate and to the maximum extent not prohibited by Applicable Law, be amortized, prorated, allocated and spread through the full term of this Agreement or such Note or other Obligation, as the case may be. (ii) Notwithstanding the other provisions of this Agreement or of any Note regarding interest and rates of interest, if at any time or for any period the otherwise applicable rate or amount of interest provided for herein or therein (without reference to the Maximum Rate limitations of this Agreement) with respect to any Note or other Obligation would exceed the Maximum Rate, then the amount and rate of interest on such Loan or other Obligation will be limited to the Maximum Rate at such time or during such period, and at all times thereafter (including periods during which any or all of such applicable rate(s) of interest otherwise provided for herein would be less than the Maximum Rate), the interest rate on such Note or other Obligation shall (while such Note or Obligation remains outstanding) continue and remain at (but shall not exceed) the Maximum Rate until the total amount of interest accrued on such Note or other Obligation equals the -20- amount of interest that would have accrued thereon if the applicable rate of interest otherwise provided for herein (without reference to the Maximum Rate limitation) had at all times been in effect; PROVIDED, HOWEVER, that in no event will the aggregate of all interest charged, received, contracted for, payable or paid in connection with the any Note or other Obligation exceed an amount equal to interest on such Note or other Obligation during the period such are outstanding, incurred or existing at the Maximum Rate, so long (and for such periods) as the Maximum Rate will be applicable to this Agreement and the transactions contemplated hereby. If, at maturity or final payment of any Note or other Obligation, as applicable, the total amount of interest paid or accrued on such Note or other Obligation under the foregoing provisions is less than the total amount of interest that would have been paid or accrued if the applicable contractual rate of interest provided for herein (without limitation to the Maximum Rate) had at all times been in effect, then the Borrowers agree, to the fullest extent permitted by and in compliance with Applicable Law, to pay an amount equal to the difference between (x) the lesser of (A) the amount of interest that would have been paid or accrued on such Note or other Obligation, as applicable, if the Maximum Rate had at all times been in effect and (B) the amount of interest that would have been paid or accrued on such Note or other Obligation, as applicable, if a rate per annum equal to the applicable contractual rate of interest provided for herein (without limitation to the Maximum Rate) had at all times been in effect, and (y) the amount of interest paid or accrued in accordance with the other provisions of such Note or other Obligation, as applicable. Section 2.8 FEES. (a) ORIGINATION FEE. The Borrowers together shall pay the Lender a fully earned and non-refundable origination fee of $175,000, due and payable upon the Funding Date. (b) UNUSED LINE FEE. For the purposes of this SECTION 2.8(b), "Unused Amount" means the Maximum Line Amount reduced by the sum of outstanding Revolving Advances and the L/C Amount. Each Borrower agrees to pay to the Lender an aggregate unused line fee (the "Unused Line Fee") at the rate of one-half of one percent (0.50%) 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. (c) COLLATERAL EXAM FEES. Each 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 any 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. -21- (d) LETTER OF CREDIT FEES. The Borrower for whose account any Letter of Credit is issued shall pay to the Lender a fee with respect to such Letter of Credit, if any, accruing on a daily basis and computed at an annual rate of three and one-half percent (3.5%) 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 the Lender, due and payable monthly in arrears on the first day of each month and on the Termination Date; PROVIDED, HOWEVER, that during Default Periods, in the Lender's sole discretion and without waiving any of its other rights and remedies, such fee shall increase to six and one-half percent (6.5%) of the Aggregate Face Amount. The foregoing fee shall be in addition to any and all fees, commissions and charges of Wells Fargo Bank with respect to or in connection with such Letter of Credit. (e) LETTER OF CREDIT ADMINISTRATIVE FEES. The Borrower for whose account any Letter of Credit is issued shall pay to the Lender all administrative fees charged by Wells Fargo Bank 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 Wells Fargo Bank for such services rendered on behalf of customers of Wells Fargo Bank generally. (f) TERMINATION AND LINE REDUCTION FEES. If the Credit Facility is terminated (i) by the Lender during a Default Period that begins before the Maturity Date, (ii) by any Borrower (A) as of a date other than the Maturity Date or (B) as of the Maturity Date but without the Lender having received written notice of such termination at least thirty (30) days before such Maturity Date, or if any Borrower reduces the Maximum Line Amount, the Borrowers shall pay to the Lender a 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) as follows: (A) two percent (2%) if the termination or reduction occurs on or before the first anniversary of the Funding Date; and (B) one percent (1%) if the termination or reduction occurs after the first anniversary of the Funding Date. (g) PREPAYMENT FEES. If the Term A Note or the Term B Note is prepaid for any reason (other than in accordance with SECTION 2.6), whether voluntarily or by acceleration, the Borrowers shall pay to the Lender a prepayment fee in an amount equal to (i) two percent (2%) of the amount prepaid, if prepayment occurs on or before the first anniversary of the Funding Date; (ii) one percent (1%) of the amount prepaid, if prepayment occurs after the first anniversary of the Funding Date. (h) WAIVER OF TERMINATION AND PREPAYMENT FEES. Each Borrower, will be excused from the payment of termination and prepayment fees otherwise due under SECTION 2.8(f) and SECTION 2.8(g) (i) if such termination or prepayment is made because of refinancing of such Borrower in full through Wells Fargo Bank or (ii) if up to fifty percent (50%) of the outstanding principal and accrued interest on such Term A Note or Term B Note shall be refinanced with funds raised from new equity issuances of Allis Chalmers or (iii) for up to $100,000 in prepayments of the Term A Note in any fiscal year using proceeds of sales of Equipment in accordance with SECTION 6.17. -22- (i) OVERADVANCE FEES. The Borrower shall pay a fee for each Overadvance in the minimum amount of $500 for each day or portion thereof that Revolving Advances exceed the Borrowing Base, regardless of how the Overadvance arises or whether or not the Overadvance has been agreed to in advance by Lender; PROVIDED, HOWEVER, that payment of any such Overadvance fee shall not be deemed to constitute either consent to the Overadvance or the waiver of any Event of Default arising as the result of an Overadvance not otherwise consented to in advance by Lender. (j) OTHER FEES AND CHARGES; PAYMENT OF FEES. 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 2.9 TIME FOR INTEREST PAYMENTS; PAYMENT ON NON-BUSINESS DAYS; COMPUTATION OF INTEREST AND FEES. (a) TIME FOR INTEREST PAYMENTS. Accrued and unpaid interest 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. (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 three hundred sixty (360) days. Section 2.10 LOCKBOX AND COLLATERAL ACCOUNT; SWEEP OF FUNDS. (a) LOCKBOX AND COLLATERAL ACCOUNT. (i) Each Borrower shall instruct all account debtors to pay all Accounts directly to the Lockbox. If, notwithstanding such instructions, any Borrower receives any payments on Accounts, such Borrower shall deposit such payments into the Collateral Account. Each Borrower shall also deposit all other cash proceeds of Collateral regardless of source or nature directly into the Collateral Account. Until -23- so deposited, such 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 Obligations. (ii) All items deposited in the Collateral Account shall be subject to final payment. If any such item is returned uncollected, such 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 such Borrower's commercial account or other account. Each Borrower shall be liable as an endorser on all items deposited in the Collateral Account, whether or not in fact endorsed by such Borrower. (b) SWEEP OF FUNDS. The Lender shall from time to time, in accordance with the applicable Wholesale Lockbox and Collection Account Agreement, cause funds in each Borrower's Collateral Account to be transferred to the Lender's general account for payment of Obligations that are then due and payable. Amounts deposited in the Collateral Account shall not be subject to withdrawal by such Borrower, EXCEPT after payment in full and discharge of all Obligations. Section 2.11 VOLUNTARY PREPAYMENT; REDUCTION OF THE MAXIMUM LINE AMOUNT; TERMINATION OF THE CREDIT FACILITY BY THE BORROWERS. Except as otherwise provided herein, the Borrowers may prepay the Advances in whole at any time or from time to time in part. Any Borrower may prepay the Term A Advance or the Term B Advances, terminate the Credit Facility or reduce the Maximum Line Amount at any time if such Borrower (i) gives the Lender at least thirty (30) days prior written notice and (ii) pays the Lender termination fees, prepayment fees, contracted funds breakage fees and Maximum Line Amount reduction fees in accordance with SECTION 2.8(f) and SECTION 2.8(g). Any reduction in the Maximum Line Amount shall be in integral multiples of $100,000, and with a minimum reduction of at least $500,000. If any Borrower terminates the Credit Facility or reduces the Maximum Line Amount to zero (0), all Obligations shall be immediately due and payable, and if such Borrower gives Lender less than the required thirty (30) days notice, such Borrower shall be liable for payment of additional interest for each day that the notice was short of the required thirty (30) day notice, which interest shall be the greater of the Minimum Interest Charge or Unused Line Fee calculated based on the Borrowers' average borrowings under the Credit Facility for the six (6) months prior to the date that any Borrower gives notice of its intent to terminate the Credit Facility or reduce the Maximum Line Amount. Subject to termination of the Credit Facility and payment and performance of all Obligations, the Lender shall, at the Borrowers' expense and within the time periods required under applicable law, release or terminate any filings or other agreements that perfect the Security Interest. -24- Section 2.12 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 Borrowers shall (i) FIRST, immediately prepay the Revolving Advances to the extent necessary to eliminate such excess; and (ii) SECOND, 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 payment received by the Lender under this SECTION 2.12 or under SECTION 2.11 may be applied to the Obligations, in such order and in such amounts as the Lender in its sole discretion may determine from time to time. Section 2.13 REVOLVING ADVANCES TO PAY OBLIGATIONS. Notwithstanding the terms of SECTION 2.1, the Lender may, in its discretion at any time or from time to time, without any 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 Obligations from time to time due and payable, and may deliver the proceeds of any such Revolving Advance to Wells Fargo Bank to pay any unpaid Wells Fargo Bank Obligations. Section 2.14 USE OF PROCEEDS. Each Borrower shall use the proceeds of Advances and each Letter of Credit issued for its account in accordance with SCHEDULE 2.14 and for ordinary working capital purposes. Section 2.15 LIABILITY RECORDS. The 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 a Borrower establishes the contrary. Upon the Lender's demand, each Borrower will admit and certify in writing the exact principal balance of the Obligations that such Borrower then asserts to be outstanding. Any billing statement or accounting rendered by the Lender shall be conclusive and fully binding on the Borrowers unless a Borrower gives the Lender specific written notice of exception within thirty (30) days after receipt. ARTICLE III SECURITY INTEREST; OCCUPANCY; SETOFF Section 3.1 GRANT OF SECURITY INTEREST. Each Borrower hereby pledges, assigns and grants to the Lender, for the benefit of itself and Wells Fargo Bank with respect to Wells Fargo Bank 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 the Lender, each Borrower will grant the Lender, for the benefit of itself and Wells Fargo Bank, with respect to any Wells Fargo Bank Obligations, a security interest in all commercial tort claims it may have against any Person. Section 3.2 NOTIFICATION OF ACCOUNT DEBTORS AND OTHER OBLIGORS. The Lender may at any time during a Default Period notify any account debtor or other person obligated to pay the amount due that such right to payment has been assigned or transferred to the Lender for security and shall be paid directly to the Lender. Each Borrower will join in giving such notice if the Lender so requests. At any time after such 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 such 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 -25- 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. The Lender may, in the Lender's name or in such Borrower's name, as such Borrower's agent and attorney-in-fact, notify the United States Postal Service to change the address for delivery of such Borrower's mail to any address designated by the Lender, otherwise intercept such Borrower's mail, and receive, open and dispose of such Borrower's mail, applying all Collateral as permitted under this Agreement and holding all other mail for such Borrower's account or forwarding such mail to such Borrower's last known address.

Each Indemnitee will use its best efforts to cooperate in the defense of any such action, suit or proceeding.

Each Borrower's obligation under this SECTION 8.6 shall survive the termination of this Agreement and the discharge of such Borrower's other obligations hereunder. -53- Section 8.7 PARTICIPANTS.

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.

The Secured Party may notify any account debtor, or any other person obligated to pay any amount due, that such chattel paper, Account, or other right to payment has been assigned or transferred to the Secured Party for security and shall be paid directly to the Secured Party.

ASSIGNMENT OF INSURANCE. The Debtor hereby assigns to the Secured Party, as additional security for the payment of the Obligations, any and all moneys (including but not limited to proceeds of insurance and refunds of unearned premiums) due or to become due under, and all other rights of the Debtor under or with respect to, any and all policies of insurance covering the Collateral, and the Debtor hereby directs the issuer of any such policy to pay any such moneys directly to the Secured Party.

A waiver signed by the Secured Party shall be effective only in the specific instance and for the specific purpose given. Mere delay or failure to act shall not preclude the exercise or enforcement of any of the Secured Party's rights or remedies. All rights and remedies of the Secured Party shall be cumulative and may be 8 exercised singularly or concurrently, at the Secured Party's option, and the exercise or enforcement of any one such right or remedy shall neither be a condition to nor bar the exercise or enforcement of any other.

The Secured Party shall not be obligated to preserve any rights the Debtor 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 Collateral in any particular order of application. This Agreement shall be binding upon and inure to the benefit of the Debtor and the Secured Party and their respective successors and assigns and shall take effect when signed by the Debtor and delivered to the Secured Party, and the Debtor waives notice of the Secured Party's acceptance hereof. The Secured Party may execute this Agreement if appropriate for the purpose of filing, but the failure of the Secured Party to execute this Agreement shall not affect or impair the validity or effectiveness of this Agreement. This Agreement shall be governed by and construed in accordance with the substantive laws (other than conflict laws) of the State of Minnesota. If any provision or application of this Agreement is held unlawful or unenforceable in any respect, such illegality or unenforceability shall not affect other provisions or applications which can be given effect and this Agreement shall be construed as if the unlawful or unenforceable provision or application had never been contained herein or prescribed hereby.

Further, if the Debtor at any time fails to perform or observe any agreement contained in SECTION 3(h), and if such failure continues for a period of ten (10) days after the Secured Party gives the Debtor written notice thereof (or, in the case of the agreements contained in clauses (vii) and (viii) of SECTION 3(h), immediately upon the occurrence of such failure, without notice or lapse of time), the Secured Party may (but need not) perform or observe such agreement on behalf and in the name, place and stead of the Debtor (or, at the Secured Party's option, in the Secured Party's own name) and may (but need not) take any and all other actions which the Secured Party may reasonably deem necessary to cure or correct such failure (including, without limitation the payment of taxes, the satisfaction of security interests, liens, or encumbrances, the performance of obligations under contracts or agreements with account debtors or other obligors, the procurement and maintenance of insurance, the filing of financing statements, the endorsement of instruments, and the procurement of repairs or transportation); and, except to the extent that the effect of such payment would be to render any loan or forbearance of money usurious or otherwise illegal under any applicable law, the Debtor shall thereupon pay the Secured Party on demand the amount of all moneys expended and all costs and expenses (including reasonable attorneys' fees) incurred by the Secured Party in connection with or as a result of the Secured Party's performing or observing such agreements or taking such actions, together with interest thereon from the date expended or incurred by the Secured Party at the highest rate then applicable to any of the Obligations. To facilitate the performance or observance by the Secured Party of such agreements of the Debtor, the Debtor hereby irrevocably appoints (which appointment is coupled with an interest) the Secured Party, or its delegate, as the attorney-in-fact of the Debtor 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 the Debtor, any and all instruments, documents, financing statements, applications for insurance and other agreements and writings required to be obtained, executed, delivered or endorsed by the Debtor under this SECTION 3 and SECTION 4. 4. RIGHTS OF SECURED PARTY. At any time and from time to time, whether before or after an Event of Default, the Secured Party may take any or all of the following actions: (a) ACCOUNT VERIFICATION. The Secured Party may at any time and from time to time send or require the Debtor to send requests for verification of accounts or notices of assignment to account debtors and other obligors. The Secured Party may also at any time and from time to time telephone account debtors and other obligors to verify accounts. 6 (b) COLLATERAL ACCOUNT. The Secured Party may establish a collateral account for the deposit of checks, drafts and cash payments made by the Debtor's account debtors. If a collateral account is so established, the Debtor shall promptly deliver to the Secured Party, for deposit into said collateral account, all payments on Accounts and chattel paper received by it. All such payments shall be delivered to the Secured Party in the form received (except for the Debtor's endorsement where necessary). Until so deposited, all payments on Accounts and chattel paper received by the Debtor shall be held in trust by the Debtor for and as the property of the Secured Party and shall not be commingled with any funds or property of the Debtor. All deposits in said collateral account shall constitute proceeds of Collateral and shall not constitute payment of any Obligation. Unless otherwise agreed in writing, the Debtor shall have no right to withdraw amounts on deposit in any collateral account. (c) LOCKBOX. The Secured Party may, by notice to the Debtor, require the Debtor to direct each of its account debtors to make payment directly to a special lockbox to be under the control of the Secured Party. The Debtor hereby authorizes and directs the Secured Party to deposit all checks, drafts and cash payments received in said lockbox into the collateral account established as set forth above. (d) DIRECT COLLECTION. The Secured Party may notify any account debtor, or any other person obligated to pay any amount due, that such chattel paper, Account, or other right to payment has been assigned or transferred to the Secured Party for security and shall be paid directly to the Secured Party. At any time after the Secured Party or the Debtor gives such notice to an account debtor or other obligor, the Secured Party may (but need not), in its own name or in the Debtor'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 chattel paper, Account, or other 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. 5. ASSIGNMENT OF INSURANCE. The Debtor hereby assigns to the Secured Party, as additional security for the payment of the Obligations, any and all moneys (including but not limited to proceeds of insurance and refunds of unearned premiums) due or to become due under, and all other rights of the Debtor under or with respect to, any and all policies of insurance covering the Collateral, and the Debtor hereby directs the issuer of any such policy to pay any such moneys directly to the Secured Party. After the occurrence of an Event of Default, the Secured Party may (but need not), in its own name or in the Debtor's name, execute and deliver proofs of claim, receive all such moneys, endorse checks and other instruments representing payment of such moneys, and adjust, litigate, compromise or release any claim against the issuer of any such policy. 7 6. EVENTS OF DEFAULT. Each of the following occurrences shall constitute an event of default under this Agreement (herein called "Event of Default"): (i) an Event of Default shall occur under the Credit Agreement; or (ii) the Debtor shall fail to pay any or all of the Obligations when due or (if payable on demand) on demand; or (iii) the Debtor shall fail to observe or perform any covenant or agreement herein binding on it. 7. REMEDIES UPON EVENT OF DEFAULT. Upon the occurrence of an Event of Default and at any time thereafter, the Secured Party may exercise any one or more of the following rights and remedies: (i) declare all unmatured Obligations to be immediately due and payable, and the same shall thereupon be immediately due and payable, without presentment or other notice or demand; (ii) exercise and enforce any or all rights and remedies available upon default to a secured party under the UCC, including but not limited to the right to take possession of any Collateral, proceeding without judicial process or by judicial process (without a prior hearing or notice thereof, which the Debtor hereby expressly waives), and the right to sell, lease or otherwise dispose of any or all of the Collateral, and in connection therewith, the Secured Party may require the Debtor to make the Collateral available to the Secured Party at a place to be designated by the Secured Party which is reasonably convenient to both parties, and if notice to the Debtor 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 9) at least ten (10) days prior to the date of intended disposition or other action; (iii) exercise or enforce any or all other rights or remedies available to the Secured Party by law or agreement against the Collateral, against the Debtor or against any other person or property. The Secured Party is hereby granted a nonexclusive, worldwide and royalty-free license to use or otherwise exploit all Intellectual Property Rights owned by or licensed to the Debtor that the Secured Party deems necessary or appropriate to the disposition of any Collateral. 8. OTHER PERSONAL PROPERTY. Unless at the time the Secured Party takes possession of any tangible Collateral, or within seven days thereafter, the Debtor gives written notice to the Secured Party of the existence of any goods, papers or other property of the Debtor, not affixed to or constituting a part of such Collateral, but which are located or found upon or within such Collateral, describing such property, the Secured Party shall not be responsible or liable to the Debtor for any action taken or omitted by or on behalf of the Secured Party with respect to such property. 9. NOTICES; REQUESTS FOR ACCOUNTING. All notices and other communications hereunder 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, or (d) transmitted by telecopy, in each case addressed or telecopied to the party to whom notice is being given at its address or telecopier number as set forth below its signature or, as to each party, at such other address or telecopier number as may hereafter be designated by such party in a written notice to the other party complying as to delivery with the terms of this Section.

The Debtor requests that the Secured Party respond to all such requests which on their face appear to come from an authorized individual and releases the Secured Party from any liability for so responding. The Debtor shall pay Secured Party the maximum amount allowed by law for responding to such requests. 8 10. MISCELLANEOUS. This Agreement has been duly and validly authorized by all necessary corporate action. This Agreement does not contemplate a sale of accounts, or chattel paper. This Agreement can be waived, modified, amended, terminated or discharged, and the Security Interest can be released, only explicitly in a writing signed by the Secured Party, and, in the case of amendment or modification, in a writing signed by the Debtor. A waiver signed by the Secured Party shall be effective only in the specific instance and for the specific purpose given. Mere delay or failure to act shall not preclude the exercise or enforcement of any of the Secured Party's rights or remedies. All rights and remedies of the Secured Party shall be cumulative and may be exercised singularly or concurrently, at the Secured Party's option, and the exercise or enforcement of any one such right or remedy shall neither be a condition to nor bar the exercise or enforcement of any other. The Secured Party's duty of care with respect to Collateral in its possession (as imposed by law) shall be deemed fulfilled if the Secured Party exercises reasonable care in physically safekeeping 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 Secured Party need not otherwise preserve, protect, insure or care for any Collateral. The Secured Party shall not be obligated to preserve any rights the Debtor 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 Collateral in any particular order of application. This Agreement shall be binding upon and inure to the benefit of the Debtor and the Secured Party and their respective successors and assigns and shall take effect when signed by the Debtor and delivered to the Secured Party, and the Debtor waives notice of the Secured Party's acceptance hereof.
