SECTION 2. REVOLVING CREDIT FACILITY

2.1 Revolving Advances.»

The Lender may, in its sole discretion, make advances to the Borrower from time to time from the date all of the conditions set forth in Sections 3.1, 3.2, and 3.3 are satisfied (the "Funding Date") to the Termination Date, on the terms and subject to the conditions herein set forth (the "Revolving Advances"). The Lender shall not consider any request for a Revolving Advance to the extent the amount of the requested Revolving Advance exceeds Availability. The Borrower’s obligation to pay the Revolving Advances shall be evidenced by the Revolving Note and shall be secured by the Collateral. Within the limits set forth in this Section II, the Borrower may request Revolving Advances, repay pursuant to Section II hereof and request additional Revolving Advances.

2.1.1 Procedures for Requesting Revolving Advances. On the Funding Date, the Lender shall make the following Revolving Advances (collectively, the “Funding Date Advances”): (a) an initial Revolving Advance of $4,000,000 to the Borrower, (b) a Revolving Advance of $250,000 to the Lender to pre-pay estimated interest coming due under the Revolving Credit Facility for the first three (3) months of the Revolving Credit Facility (the “Prepaid Interest Advance”), (c) a Revolving Advance of $210,000 to the Lender to pay the fees due to the Lender under Sections 2.5.1 and 2.5.2 hereof, and (d) a Revolving Advance of $150,000.00 to the Lender’s counsel to pay for the estimated costs and expenses incurred by the Lender in connection with the negotiation and preparation of this Agreement and the other Financing Agreements. Thereafter, the Lender may, in its discretion, make additional Revolving Advances from time to time at the request of the Borrower, provided that (i) such Revolving Advances shall be made no more frequently than once per month and no later than the fifth Business Day of each calendar month, (ii) such request is made in writing at least ten (10) days prior to the date on which such Revolving Advance is to be funded, and is accompanied by an executed Compliance Certificate, (iii) such request shall be for Revolving Advances to pay for costs and expenses incurred in connection with the installation of the COES Installations in accordance with the Build Out Draw Schedule, and (iv) all borrowings after the Funding Date Advances shall be in multiples of $100,000. There shall not be any recourse to, nor liability of, the Lender on account of any of the following: (x) any delay in the Lender’s making of, and/or any decline by the Lender to make, any Revolving Advance, (y) any delay in the proceeds of any such Revolving Advance constituting collected funds, and (z) any delay in the receipt, and/or any loss, of funds which constitute a Revolving Advance, the wire transfer of which was properly initiated by the Lender in accordance with wire instructions provided to the Lender by the Borrower.

The Lender may rely on any request for a Revolving Advance which the Lender, in good faith believes to have been made by a person duly authorized to act on behalf of the Borrower and may decline to make any such requested Revolving Advance pending the Lender’s being furnished with such documentation concerning that person’s authority to act as may be satisfactory to the Lender.

2.1.2 Loan Account.

(a) An account (the “Loan Account”) shall be opened on the books of the Lender, in which Loan Account a record may be kept of all Revolving Advances made by the Lender to the Borrower under or pursuant to this Agreement and of all payments thereon.

(b) The Lender may also keep a record (either in the Loan Account or elsewhere, as the Lender may from time to time elect) of all interest, fees, service charges, costs, expenses, and other debits owed the Lender on account of the Obligations and of all credits against such amounts so owed.

(c) All credits against the Obligations shall be conditional upon final payment to the Lender of the items giving rise to such credits. The amount of any item credited against the Obligations which is charged back against the Lender for any reason or is not so paid shall be an Obligation and shall be added to the Loan Account, whether or not the item so charged back or not so paid is returned.

(d) Except as otherwise provided herein, all fees, service charges, costs, and expenses for which the Borrower is obligated hereunder are payable on demand. In the determination of Availability, the Lender may deem fees, service charges, accrued interest, and other payments as having been advanced under the Revolving Credit Facility whether or not such amounts are then due and payable.

(e) The Lender, without the request of the Borrower, may advance under the Revolving Credit Facility any interest, fee, service charge, or other payment to which the Lender is entitled from the Borrower pursuant hereto and may charge the same to the Loan Account notwithstanding that such amount so advanced may result in Availability’s being exceeded. Such action on the part of the Lender shall not constitute a waiver of the Lender’s rights under Section 2.1. Any amount which is added to the principal balance of the Loan Account as provided in this Subsection shall bear interest at the interest rate applicable from time to time to the unpaid principal balance of the Revolving Advances.

(f) Any written statement rendered by the Lender to the Borrower concerning the Obligations shall be considered correct and accepted by the Borrower and shall be conclusively binding upon the Borrower unless the Borrower provides the Lender with written objection thereto within twenty (20) days from the mailing of such statement, which written objection shall indicate, with particularity, the reason for such objection. The Loan Account and the Lender’s books and records concerning the loan arrangement contemplated herein and the Obligations shall be prima facie evidence and proof of the items described therein.

2.2 Interest.»

The Revolving Advances shall bear interest as follows:

2.2.1 Interest Rate. The outstanding principal amount of the Revolving Advances shall bear interest at a rate of twenty percent (20%) per annum. The first three months of interest payments due under the Revolving Credit Facility shall have been prepaid to the Lender pursuant to the Prepaid Interest Advance. Thereafter, the Borrower shall pay accrued interest on the outstanding principal amount of the Revolving Advances at the foregoing rate monthly in arrears on the first day of each month beginning on the first day of the fourth month immediately following the Funding Date, and at the Termination Date (whether by acceleration or otherwise). Interest shall be computed on the basis of a 360-day year over the actual number of days elapsed.

2.2.2 Interest Upon Event of Default. Upon the occurrence and during the continuance of an Event of Default (and whether or not the Lender accelerates payment or exercises any of Lender’s other rights on account thereof), interest shall accrue, at the option of the Lender, on the unpaid Obligations at a rate per annum equal to four (4%) percent in excess of the rate otherwise applicable to such Obligations, but in no event in excess of the maximum rate permitted by applicable law. Interest accruing at the foregoing rate shall be due and payable upon demand by the Lender.

2.2.3 Maximum Rate. Notwithstanding anything otherwise in this Section 2.2 or Section 2.3.2 to the contrary, the rate of interest payable by the Borrower shall not exceed the maximum rate permitted by applicable law. In the event the interest paid by the Borrower shall exceed the maximum lawful rate, at the Lender’s option, the excess shall be applied in reduction of the principal balance of the Revolving Advances, or repaid to the Borrower.

2.3 Cash Management; Prepayment; Payments.

2.3.1 Cash Management. (a) Borrower shall establish and maintain, at its expense, a lockbox and related blocked account (the "Blocked Account"), as Lender may specify, with bank which is acceptable to Lender into which Borrower shall promptly deposit and direct its account debtors to directly remit, on a daily basis, all payments and receipts in the identical form in which such payments and receipts are made or received, whether by cash, check or other manner. Borrower shall deliver, or cause to be delivered to Lender, a Deposit Account Control Agreement duly authorized, executed and delivered by such bank where the Blocked Account is maintained and Borrower shall execute and deliver such other agreements or documents as Lender may require in connection therewith. In addition, Borrower shall take the necessary steps to allow Lender “read only” online access to the Blocked Account so that Lender may electronically monitor the Blocked Account at any time and from time to time in its discretion.

(b) Borrower and its employees and agents shall, acting as trustee for Lender, receive, as the property of Lender, any monies, checks, notes, drafts or any other payment relating to and/or proceeds of Collateral which come into their possession or under their control and immediately upon receipt thereof, shall deposit or cause the same to be deposited in the Blocked Account, or remit the same or cause the same to be remitted, in kind, to Lender. In no event shall the same be commingled with Borrower's own funds. Borrower agrees to reimburse Lender on demand for any amounts owed or paid to any bank or other financial institution at which a Blocked Account or any other deposit account or investment account is established or any other bank, financial institution or other person involved in the transfer of funds to or from the Blocked Account arising out of Lender's payments to or indemnification of such bank, financial institution or other person.

2.3.3 Repayment of Obligations.»

The Borrower shall repay the Obligations as follows:

(a) The Borrower, without notice or demand from the Lender, shall pay the Lender that amount, from time to time, which is necessary so that the aggregate outstanding principal balance of the Revolving Advances does not exceed Availability.

(b) Accrued interest shall be paid as set forth in Section 2.2, above.

On the fifth day of each month, the Borrower shall provide the Lender with a “true up” calculation of the Borrower’s actual EBITDA for the prior month versus the Estimated EBITDA Payments made during the prior month pursuant to the foregoing sentence. If the “true up” calculation indicates that the aggregate Estimated EBITDA Payments made by the Borrower were less than 30% of its actual EBITDA for the prior month, then the Borrower shall promptly pay the difference to the Lender. If the “true up” calculation indicates that the aggregate Estimated EBITDA Payments made by the Borrower were more than 30% of its actual EBITDA for the prior month to the Lender, and the aggregate of such Estimated EBITDA Payments exceed the minimum $100,000.00 monthly payment set forth in Section 2.3.3(d) hereof, then the Estimated EBITDA Payments to be made for the then current month shall be reduced by an appropriate amount until such excess payment is returned to the Borrower.

From and after the occurrence of a Default or an Event of Default, at the Lender’s option, 100% of such receipts shall be applied in reduction of the Obligations in a manner determined by the Lender in its sole and exclusive discretion. Any payments received by the Lender hereunder will not be deemed applied in reduction of the Obligations unless and until such payments have been received in good and collected funds. In the event that at any time or from time to time there are no Obligations outstanding, 100% of such receipts shall be remitted to the Borrower’s Operating Account.

(d) Commencing on July 1, 2008, and continuing on the first day of each month thereafter, the Borrower shall make monthly principal payments to the Lender in an amount (if a positive number) equal to the difference between (i) $100,000, and (ii) the amounts paid to the Lender pursuant to Section 2.3.3(c) hereof.

2.3.4 Manner of Payment. Except as otherwise expressly set forth herein, all payments required to be made by the Borrower hereunder on account of principal, interest, or fees shall be made by wire transfer, in Dollars, in immediately available funds as set forth herein.

The Borrower authorizes (but shall not require) the Lender to debit any account maintained by the Borrower on any date on which a payment is due to the Lender hereunder or under any of the Financing Agreements, in an amount equal to any unpaid portion of such payment.

To the extent permitted by applicable law, Borrower shall not assert, and Borrower hereby waives, any claim against Lender, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any of the other Financing Agreements or any undertaking or transaction contemplated hereby.

(Pending Litigation; Investigations)

GREENSHIFT CORPORATION

1. GreenShift is party to the matter entitled XxXxxxx x. Xxxxxx, et. al., which action was filed in the Superior Court of Connecticut. The verified complaint seeks damages relating to the acquisition by General Ultrasonics of the stock of H2 Energy Solutions, Inc. from substantially all of its shareholders, as well as attorney's fees and costs. GreenShift has responded to the verified complaint and denies any liability.

2. GreenShift is party to the matter entitled O'Brien & Xxxx Limited, et al v. NextGen Chemical Processors, Inc., et al., which action was filed in the Supreme Court of the State of New York. The verified complaint, which also names GreenShift and certain of its affiliates, seeks performance of and damages relating to certain service and related agreements, plus attorney's fees and costs. This matter relates to the provision by plaintiffs of certain engineering services to NextGen Chemical Processors, Inc. ("NCP") during 2005 and 2006. NCP is owned by the former shareholders of our recently acquired NextGen Fuel, Inc., subsidiary. GreenShift has responded to the verified complaint and denies any liability.

GS CLEANTECH CORPORATION

1. On February 28, 2007 GS CleanTech entered into a Stipulation of Settlement to settle the lawsuit titled Xxxxx Manufacturing Corp. v. KBF Pollution Management, Inc., which was pending in the Supreme Court of the State of New York (County of Queens, Index No. 19788/03). Pursuant to the Stipulation, GS CleanTech issued to Xxxxx (a) a Convertible Debenture in the principal amount of $500,000 that was paid on March 31, 2007 and (b) a convertible debenture in the principal amount of $1,000,000 that was due on June 30, 2007. The Stipulation provides that upon satisfaction of all obligations under the Stipulation, the parties will exchange mutual general releases. In April 2007, the entire principal balance on the March 31, 2007 Xxxxx debenture was paid in full. GS CleanTech failed to pay the June 30, 2007 payment and Xxxxx accordingly filed motion for summary judgment in lieu of complaint in the Supreme Court of the State of New York, Queens County, seeking $1,000,000 in damages and ancillary relief. GS CleanTech subsequently entered into an amended agreement dated September 10, 2007 extending the due date to January 15, 2008. The agreement calls for a $30,000 interest payment to be paid on or before September 10, 2007 and interest payments of $10,000 to be paid on or before the first of each month through January 2008. As of the nine months ending September 30, 2007, all interest payments have been paid in accordance with the agreement.

GS AGRIFUELS CORPORATION

1. GS AgriFuels is party to the matter entitled O'Brien & Xxxx Limited, et al v. NextGen Chemical Processors, Inc., et al., which action was filed in the Supreme Court of the State of New York. The verified complaint, which also names the Company and certain of its affiliates, seeks performance of and damages relating to certain service and related agreements, plus attorney's fees and costs. This matter relates to the provision by plaintiffs of certain engineering services to NextGen Chemical Processors, Inc. ("NCP") during 2005 and 2006. NCP is owned by the former shareholders of our recently acquired NextGen Fuel, Inc., subsidiary. GS AgriFuels has responded to the verified complaint and denies any liability. GS AgriFuels estimates that the legal fees for our defense will be nominal, if any, as the sellers have been paying the fees to date. On September 19, 2007, the Supreme Court of the State of New York dismissed a significant portion of O'Brien & Gere's complaint with prejudice.

2. On October 30, 2006, a wholly-owned subsidiary of GS AgriFuels purchased 100% of the outstanding capital stock of NextGen Fuel, Inc. NextGen Fuel is engaged in the business of developing and distributing esterification and transesterification biodiesel process technologies. The purchase price was $21,204,437, of which $17,000,000 was paid at closing and the balance of $4,204,437 was to be paid in the form of an earn-out. $3,204,437 of the earn-out was to remain in holdback for 12 months after closing or sooner if NextGen Fuel has realized revenue of $7,500,000 subsequent to the acquisition and there are no claims for indemnification by GS AgriFuels. The remaining $1,000,000 earn out is due to a sales consultant and is payable upon the payment by customers for biodiesel production systems totaling forty million gallons per year of production capacity, on a pro-rated basis such that the consultant shall receive payments of $250,000 with each ten million gallon per year system on a pro-rated basis with NextGen Fuel’s receipt of cash payments for such system. The outstanding earn out amount at September 30, 2007 was $4,060,032, but is subject to adjustment under the terms of the acquisition agreement based on a gross margin calculation related to sales contracted prior to closing.
