This GLOBAL GUARANTY AGREEMENT dated as of June __, 2010 (the “Guaranty”), is given by each of the individuals and entities listed on Schedule 1 attached hereto following (jointly, severally, and collectively, the “Guarantors”) in favor of YA CORN OIL SYSTEMS, LLC (together with its successors and assigns, the “Secured Party”). Capitalized terms used herein and not otherwise defined herein shall have the respective meanings set forth in the Security Agreement (as defined below).

WHEREAS:

A. GreenShift Corporation (“GreenShift”) and the Secured Party have entered into a certain Management Agreement of even date herewith (the “Management Agreement”) pursuant to which GreenShift has agreed to perform management services in connection with certain corn oil extraction systems owned by the Secured Party in consideration for a monthly fee and, subject to the terms and conditions of the Management Agreement, the Secured Party making certain payments to YA Global Investments, L.P. (“YA Global”) for application in reduction of GreenShift’s and the Guarantors’ obligations and liabilities to YA Global.

B. Upon the mutual agreement of GS CleanTech Corporation (“CleanTech”) and the Secured Party, CleanTech may from time to time sell, pursuant to Sale and Assignment Agreements substantially in the form attached hereto as Exhibit A (the “Royalty Sale Agreement”) rights to receive royalties from licenses of certain patent rights granted by CleanTech to third parties (the “Royalties”). Pursuant to the terms of each Royalty Sale Agreement, Secured Party has a limited right to put the applicable Royalties back to the Assignor.

C. Each of the Guarantors has executed and delivered a Global Security Agreement, dated as of the date hereof (as may be amended and supplemented from time to time, the “Security Agreement”), pursuant to which the Guarantors pledged and granted to the Secured Party a security interest in and to all of the Guarantors’ assets and personal property;

D. The Guarantors will directly benefit from the Management Agreement, any sale of Royalties and from the financial accommodations made by the Secured Party to GreenShift pursuant to the Management Agreement and the various agreements and transactions referenced therein, and each Guarantor acknowledges that without this Guaranty, the Secured Party would not be willing to enter into the Management Agreement or make such accommodations.

NOW, THEREFORE, in consideration of the premises and the mutual covenants set forth herein, and for other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, each Guarantor hereby agrees as follows:

SECTION 1 Guaranty.

1.1 Guaranty.

(a) Each Guarantor, as direct obligor and not merely as surety, hereby unconditionally, absolutely, and irrevocably guarantees to the Secured Party the full payment and prompt performance of all of the Obligations. Without limiting the foregoing, the Guarantors hereby agree that upon any Event of Default, the Guarantors shall immediately pay or perform any Obligations without notice, demand or formality of any kind.

(b) The term “Obligations” shall mean and include any and all debts, liabilities, obligations, covenants and duties owing by any Guarantor to the Secured Party, now existing or hereafter arising of every nature, type, and description, whether liquidated, unliquidated, primary, secondary, secured, unsecured, direct, indirect, absolute, or contingent, and whether or not evidenced by a note, guaranty or other instrument, and any amendments, extensions, renewals or increases thereof, including, without limitation, all those under (i) the Security Agreement; (ii) the Management Agreement; (iii) any agreement or document related to the Security Agreement and/or the Management Agreement; or (iv) any other or related documents, and including any interest accruing thereon after insolvency, reorganization or like proceeding relating to the Guarantors, whether or not a claim for post-petition interest is allowed in such proceeding, and all costs and expenses of the Secured Party incurred in the enforcement, collection or otherwise in connection with any of the foregoing, including, but not limited to, reasonable attorneys’ fees and expenses and all obligations of the Guarantors to the Secured Party to perform acts or refrain from taking any action.

1.2 Continuing Guaranty.

(a) The Obligations under this Guaranty are continuing, absolute, unconditional and irrevocable irrespective of the validity, regularity, enforceability or value of any of the Obligations and notwithstanding any claim, defense or right of set-off which the Guarantors may have against the Secured Party, including any such claim, defense or right based on any present or future applicable law and irrespective of any other circumstances which might otherwise constitute a legal or equitable release, defense or discharge of a surety or a guarantor. Without limiting the generality of the foregoing, the Obligations of each Guarantor hereunder shall not be discharged or impaired or otherwise affected by:

(i) any rescission, waiver, amendment or modification of any terms or provisions of the Obligations or the documents evidencing the same.

(ii) any fraudulent, illegal, or improper act by any Guarantor or any failure, omission or delay on the part of any Guarantor to conform or comply with any term of the Obligations or of this Guaranty;

(iii) any failure of the Secured Party to assert a claim or demand or to enforce or exercise any right or remedy against any Guarantor or any other guarantor for any reason;

(iv) any release or discharge by operation of law or otherwise of any Guarantor from any Obligation or the documents evidencing the same;

(v) any change in the existence, structure or ownership of any Guarantor or the legal incapacity of any Guarantor;

(vi) any insolvency, bankruptcy, reorganization, arrangement, readjustment, composition, liquidation or other similar proceeding affecting any Guarantor or its/his assets or any resulting disallowance, release or discharge of all or any portion of the Obligations;

(vii) the failure by any Guarantor or any other person to sign this Guaranty; and

(viii) any other occurrence, circumstance, happening or event, whether similar or dissimilar to the foregoing and whether foreseen or unforeseen, which otherwise might constitute a legal or equitable defense or discharge of the liabilities of a guarantor or surety or which otherwise might limit recourse against any Guarantor.

(b) This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time payment or performance of the Obligations, or any part thereof, to the Secured Party is rescinded or must otherwise be returned by the Secured Party, whether in connection with the insolvency, bankruptcy or reorganization of any Guarantor, or otherwise, all as though such payment to the Secured Party has not been made.

1.3 Guaranty of Payment and Not of Collection; Subordination.

(a) The liability of each Guarantor shall be continuing, direct and immediate and not conditional or contingent upon either the pursuit of any remedies against GreenShift or any other Guarantor, or any other person or foreclosure of any security interests or liens available to the Secured Party, its successors, endorsees or assigns. The Secured Party may accept any payment(s), plan for adjustment of debts, plan of reorganization or liquidation, or plan of composition or extension proposed by, or on behalf of, GreenShift or any Guarantor without in any way affecting or discharging the liability of any Guarantor. If the Obligations are partially paid, each Guarantor shall remain liable for any balance of such Obligations. Without limiting any other provision of, impairing or affecting this Guaranty, the Secured Party may, at any time and from time to time, take or refrain from taking, all or any actions whatsoever, including the following actions: (a) retain or obtain a Lien (as defined in the Security Agreement) in any property to secure any of the Obligations; (b) amend, extend, renew, adjust, waive or release any Obligations or the terms thereof, (c) release or fail to perfect its interest in all or any property securing any of the Obligations or permit any substitution or exchange for any such property.

(b) With respect to any sum paid or payable by a Guarantor hereunder or in connection herewith or otherwise, all rights of such Guarantor against any other Guarantor arising as a result thereof by way of right of subrogation, contribution, reimbursement, indemnity or otherwise shall in all respects be subordinate and junior in right of payment to the prior indefeasible payment or performance in full of all the Obligations. In addition, any indebtedness of any Guarantor now or hereafter held by any Guarantor is hereby subordinated in right of payment to the prior payment or performance in full of the Obligations and no Guarantor shall demand, ▇▇▇ for, or otherwise attempt to collect any such indebtedness, or prove any claim in competition with the Secured Party in respect of any payment hereunder in bankruptcy or insolvency proceedings of any nature. If any amount shall erroneously be paid to any Guarantor on account of (i) such subrogation, contribution, reimbursement, indemnity or similar right or (ii) any such indebtedness of any Guarantor as borrower of a Guarantor, such amount shall be held in trust for the benefit of the Secured Party and shall forthwith be paid to the Secured Party to be credited against the payment of the Obligations.

1.4 Discharge. Each Guarantor covenants and agrees that this Guaranty will not be discharged, except by complete performance of the Obligations.

1.5 Interest. Guarantors will pay on demand interest on all amounts due to the Secured Party under this Guaranty, or arising under any documents, instruments, or agreements relating to any collateral securing this Guaranty, from the time the Secured Party first demands payment of this Guaranty at a rate equal to the highest rate applicable to any of the Obligations after the earlier of (i) demand, or (ii) maturity, or (iii) the occurrence of any event of default under any instrument, document or agreement evidencing the Obligations (but in no event higher than the highest rate of interest which under the circumstances may be charged under applicable law).

1.6 Costs and Expenses. Without limiting any obligation of any Guarantor hereunder, each Guarantor agrees, jointly and severally, to pay all reasonable fees and costs (including, without limitation, reasonable attorneys’ fees and expenses, whether or not involving litigation and/or appellate or bankruptcy proceedings) incurred by Secured Party in (i) collecting or securing or attempting to collect or secure this Guaranty; and (ii) defending or prosecuting any actions or proceedings arising out of or relating to the Secured Party’s transactions with the Guarantors.

1.7 Indemnification. For said good and valuable consideration, the Guarantors also shall, except with respect to the Secured Party’s gross negligence, willful misconduct or fraud, indemnify, defend, and hold the Secured Party, or any agent, employee, officer, attorney, or representative of the Secured Party, harmless of and from any claim brought or threatened against the Secured Party or any such person so indemnified by: any Guarantor, any other obligor or endorser of the Obligations or any other person (as well as from attorneys’ fees and expenses in connection therewith) on account of the Secured Party’s relationship with the Guarantors, or any other obligor or endorser of the Obligations (each of which may be defended, compromised, settled, or pursued by the Secured Party with counsel of the Secured Party’s selection, but at the expense of the undersigned).

SECTION 2 Additional Guarantors.

Each subsidiary of the Guarantors that is formed or acquired after the execution of this Guaranty is required to execute the Guaranty. Such subsidiary shall become a Guarantor hereunder with the same force and effect as if originally named as a Guarantor herein. The execution and delivery of any instrument adding an additional Guarantor as a party to this Guaranty shall not require the consent of any other Guarantor hereunder. The rights and obligations of each Guarantor hereunder shall remain in full force and effect notwithstanding the addition of any new Guarantor as a party to this Guaranty.

SECTION 3 Representations and Warranties.

Each Guarantor hereby represents and warrants to the Secured Party as follows:

(a) each corporate Guarantor has full power, right and authority to enter into and perform its obligations under this Guaranty, and this Guaranty has been duly executed and delivered by each Guarantor and constitutes the valid and binding obligation of each Guarantor and is enforceable against each Guarantor in accordance with its terms.

(b) No permits, approvals or consents of or notifications to (i) any governmental entities, or (ii) any other persons or entities are necessary in connection with the execution, delivery and performance by any Guarantor of this Guaranty and the consummation by each Guarantor of the transactions contemplated hereby.

(c) Neither the execution and delivery of this Guaranty by any Guarantor nor the performance by them of the transactions contemplated hereby will:

(i) violate or conflict with or result in a breach of any provision of any law, statute, rule, regulation, order, permit, judgment, ruling, injunction, decree or other decision of any court or other tribunal or any governmental entity or agency binding on a Guarantor or his properties, or conflict with or cause an event of default under any contract or agreement of a Guarantor; or

(ii) require any authorization, consent, approval, exemption or other action by or notice to any court, administrative or governmental body, person, entity or any other third party.

(d) The Guarantors have no pending or threatened litigation, arbitration, actions or proceedings which if adversely decided could reasonably be expected to result in a material adverse effect, individually or in the aggregate, except as set forth on the attached Schedule 2.

SECTION 4. Event of Default.

(a) For purposes of this Guaranty, an “Event of Default” shall be deemed to have occurred upon the occurrence of one or more of the following after the date hereof: (i) a default or Event of Default under the Security Agreement, or (ii) the occurrence of a default under the Management Agreement.

(b) Upon the occurrence of an Event of Default, at the option of the Secured Party, all of the obligations of each Guarantor hereunder shall be immediately due and payable without any action on the part of the Secured Party, and the Secured Party shall be entitled to seek and institute any and all remedies available to it.

▇▇▇▇▇▇▇ ▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ Obligations, Breaches and Injunctive Relief.

(a) No remedy conferred under this Guaranty upon the Secured Party is intended to be exclusive of any other remedy available to the Secured Party, pursuant to the terms of this Guaranty or otherwise, at law or in equity (including a decree of specific performance and/or other injunctive relief). No single or partial exercise by the Secured Party of any right, power or remedy hereunder shall preclude any other or further exercise thereof.

(b) The failure of the Secured Party to exercise any right or remedy under this Guaranty or otherwise, or delay in exercising such right or remedy, shall not operate as a waiver thereof.

(c) Every right and remedy of the Guarantors under any document executed in connection with this transaction, including but not limited to this Guaranty, or under applicable law may be exercised from time to time and as often as may be deemed expedient by the Secured Party.

(d) The Guarantors acknowledge that a breach by a Guarantor of its/his obligations hereunder will cause irreparable harm to the Secured Party and that the remedy at law for any such breach may be inadequate. The Guarantors therefore agree that, in the event of any such breach or threatened breach by the Guarantors, the Secured Party shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, and specific performance without the necessity of showing economic loss and without any bond or other security being required. Nothing herein shall limit Secured Party’s right to pursue actual damages for any failure by a Guarantor to comply with the terms of this Guaranty.

SECTION 6 Maximum Liability.

Notwithstanding any provision herein contained to the contrary, each Guarantor’s liability under this Guaranty shall be limited to an amount not to exceed as of any date of determination the amount which could be claimed by any Secured Party from such Guarantor under this Guaranty without rendering such claim voidable or avoidable under Section 548 of the Bankruptcy Code (11 U.S.C. §§ 101 et seq.) or under any applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common law (the “Avoidance Provisions”) after taking into account, among other things, such Guarantor’s right of contribution and indemnification from each other Guarantor, if any. To the end set forth above, but only to the extent that the Obligations of a Guarantor hereunder (the “Guaranty Obligations”) would otherwise be subject to avoidance under the Avoidance Provisions, if such Guarantor is not deemed to have received valuable consideration, fair value, fair consideration or reasonably equivalent value for the Guaranty Obligations, or if the Guaranty Obligations would render such Guarantor insolvent, or leave such Guarantor with an unreasonably small capital to conduct its business, or cause such Guarantor to have incurred debts (or to have intended to have incurred debts) beyond its ability to pay such debts as they mature, in each case as of the time any of the Guaranty Obligations is deemed to have been incurred for the purposes of the Avoidance Provisions, the maximum Guaranty Obligations for which such Guarantor shall be liable hereunder shall be reduced to that amount which, after giving effect thereto, would not cause the Guaranty Obligations as so reduced, to be subject to avoidance under the Avoidance Provisions.

SECTION 7 Miscellaneous.
