Exhibit 10.1(b)

GUARANTY

THIS GUARANTY, dated as of August 29, 2017 (as amended, restated, supplemented or modified from time to time, the “Guaranty”), is executed in favor of BNP PARIBAS, as collateral agent (in such capacity, the “Collateral Agent”) and as administrative agent (in such capacity, the “Administrative Agent”) and the other Lender Parties (as defined below).

W I T N E S S E T H:

WHEREAS, Green Plains Inc. (the “Borrower”), the lenders party thereto from time to time, the Administrative Agent and the Collateral Agent, have entered into a Term Loan Agreement, dated as of the date hereof (as amended, restated, supplemented or otherwise modified from time to time, the “Loan Agreement”; capitalized terms used but not defined herein have the respective meanings ascribed thereto in the Loan Agreement); and

WHEREAS, each of the undersigned will benefit from the making of Loans pursuant to the Loan Agreement and is willing to guarantee the respective Liabilities (as defined below) as hereinafter set forth;

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each of the undersigned agrees as follows:

Each of the undersigned hereby, jointly and severally, absolutely, unconditionally and irrevocably, as primary obligor and not merely as surety, guarantees the full and prompt payment when due, whether by acceleration or otherwise, and at all times thereafter, of: (a) all obligations of the Borrower, howsoever created, arising or evidenced, whether direct or indirect, absolute or contingent, now or hereafter existing, or due or to become due, and whether for principal, interest, fees, reimbursement obligations, indemnities or otherwise (including, without limitation, interest accruing after, and advances made after, the commencement of an Insolvency Proceeding with respect to the Borrower, whether or not a claim for post-filing or post-petition interest or advances is allowed in such case or proceeding), that arise under or in connection with the Loan Agreement or any other Loan Document, as the same may be amended, modified, extended or renewed from time to time; and (b) all out-of-pocket costs and expenses (including reasonable attorneys’ fees and charges) paid or incurred by the Administrative Agent or any other Lender Party (as defined below) in enforcing this Guaranty or any other applicable Loan Document against such undersigned (all of the foregoing obligations, collectively, the “Liabilities” of such undersigned); provided that the liability of each of the undersigned hereunder shall be limited to the maximum amount of the applicable Liabilities that such undersigned may guarantee without rendering this Guaranty void or voidable with respect to such undersigned under any fraudulent conveyance or fraudulent transfer law. Each of the undersigned under this Guaranty desire to allocate among themselves, in a fair and equitable manner, their obligations arising under this Guaranty. Accordingly, in the event any payment or distribution is made on any date by any of the undersigned under this Guaranty or under any other guaranty related to the obligations under the Loan Agreement, such guarantor shall be entitled to a contribution from each of the other undersigned guarantors in the maximum amount permitted by law so as to maximize the aggregate amount of the Liabilities paid to the Lender Parties.

As used herein, “Lender Party” means the Administrative Agent, the Collateral Agent, and each Lender.

Each of the undersigned agrees that if any Event of Default occurs under Section 12.1.7 or 12.1.8 of the Loan Agreement at a time when the Liabilities are not otherwise due and payable in full (whether due to a judicial stay of acceleration or otherwise), then such undersigned will pay to the Administrative Agent for the account of the Lender Parties forthwith the full amount that would be payable hereunder by such undersigned if all Liabilities were then due and payable.

Each of the undersigned is (i) duly formed or organized and is validly existing and in good standing under the laws of the jurisdiction in which it was formed and (ii) has full power and authority to execute this Guaranty. This Guaranty has been duly and validly executed by or on behalf of each of the undersigned and constitutes the legal, valid and binding obligation of each of the undersigned and is enforceable against each of them in accordance with its terms, subject, as to enforceability, to the effect of applicable bankruptcy, insolvency and other similar laws limiting the enforcement of creditors’ rights generally and to general principles of equity. The execution, delivery and performance of this Guaranty by each of the undersigned does not and will not violate, or contravene (x) its Organizational Documents, (y) any existing license, contract, indenture or other agreement binding upon any of them or (z) any existing law, statute, regulation, order, decree or judgment applicable to any of them or their respective property. No authorization, approval, or other action by, and no notice to or filing with, any governmental authority, regulatory body or any other Person is required for the execution, delivery, and performance of this Guaranty by any of the undersigned.

To secure all obligations of each of the undersigned hereunder, the Collateral Agent and each other Lender Party shall have a Lien on and security interest in all balances, credits, deposits, accounts or moneys of or in the name of such undersigned now or hereafter held with the Collateral Agent or such other Lender Party and any and all property of every kind or description of or in the name of such undersigned now or hereafter, for any reason or purpose whatsoever, in the possession or control of, or in transit to, the Collateral Agent or such other Lender Party or any agent or bailee for the Collateral Agent or such other Lender Party. Subject to the terms of the Loan Documents and the ABL Intercreditor Agreements, each Lender Party may, at its option, offset balances held by such Lender Party for the account of any of the undersigned (at any of its offices and regardless of whether such balances are then due to such undersigned), against any Liabilities of such undersigned owing to such Lender Party that are not paid when due (by acceleration or otherwise).

This Guaranty shall in all respects be a continuing, irrevocable, absolute and unconditional guaranty of payment and performance and not merely a guaranty of collectability, and shall remain in full force and effect (notwithstanding the dissolution of any of the undersigned, that at any time or from time to time no Liabilities are outstanding or any other circumstance) until all Liabilities have been indefeasibly paid in full in cash.

2

Each of the undersigned further agrees that if at any time all or any part of any payment theretofore applied by the Administrative Agent or any other Lender Party to any of the Liabilities is or must be rescinded or returned by the Administrative Agent or such other Lender Party for any reason whatsoever (including the insolvency, bankruptcy or reorganization of the Borrower or any of the undersigned), such Liabilities shall, for purposes of this Guaranty, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence, notwithstanding such application by the Administrative Agent or such other Lender Party, and this Guaranty shall continue to be effective or be reinstated, as the case may be, as to such Liabilities, all as though such application by the Administrative Agent or such other Lender Party had not been made.

The Administrative Agent or any other Lender Party may, from time to time, at its sole discretion and without notice to any of the undersigned in their capacity as guarantors hereunder, take any or all of the following actions without affecting the obligations of any of the undersigned hereunder: (a) retain or obtain a security interest in any property to secure any of the Liabilities or any obligation hereunder, (b) retain or obtain the primary or secondary obligation of any other obligor or obligors (in addition to each of the undersigned) with respect to any of the Liabilities, (c) extend, modify, restate, amend or renew any of the Liabilities for one or more periods (whether or not longer than the original period), alter or exchange any of the Liabilities, or release or compromise any obligation of any of the undersigned hereunder or any other guarantor or any obligation of any nature of any other obligor with respect to any of the Liabilities, (d) release any security interest in, or surrender, release or permit any substitution or exchange for, any property securing any Liabilities or any obligation hereunder, or extend or renew for one or more periods (whether or not longer than the original period) or release, compromise, alter or exchange any obligations of any nature of any obligor with respect to any such property, and (e) resort to any of the undersigned for payment of any of the Liabilities when due, whether or not the Administrative Agent or such other Lender Party shall have resorted to any property securing any of the Liabilities or any obligation hereunder or shall have proceeded against any of the undersigned or any other obligor primarily or secondarily obligated with respect to any of the Liabilities.

Any amount received by the Administrative Agent or any Lender Party from whatever source on account of the Liabilities may be applied by it toward the payment of the Liabilities in accordance with the Loan Documents and, notwithstanding any payment made by or for the account of any of the undersigned pursuant to this Guaranty, each of the undersigned shall not exercise any right of subrogation to any right of any Lender Party until such time as this Guaranty shall have been terminated as to all of the undersigned and the Lender Parties shall have received final payment in cash of the full amount of all Liabilities.

In case any payment is made on account of the Liabilities by any of the undersigned or is received or collected on account of the Liabilities from any of the undersigned or its property: (a) if such payment is made by an undersigned or from its property in respect of the Liabilities of another undersigned, such undersigned shall be entitled, subject to and upon (but not before) such time as this Guaranty shall have been terminated as to all of the undersigned and the Lender Parties shall have received final payment in cash of the full amount of all Liabilities, (i) to

3

demand and enforce reimbursement for the full amount of such payment from such other undersigned, and (ii) to demand and enforce contribution in respect of such payment from each other undersigned which has not paid its fair share of such payment, as necessary to ensure that (after giving effect to any enforcement of reimbursement rights provided hereby) each undersigned pays its fair share of the unreimbursed portion of such payment; and (b) if and whenever any right of reimbursement or contribution becomes enforceable by any of the undersigned against any other undersigned whether under this paragraph or otherwise, such undersigned shall be entitled, subject to and upon (but not before) such time as this Guaranty shall have been terminated as to all of the undersigned and the Lender Parties shall have received final payment in cash of the full amount of all Liabilities, to be subrogated (equally and ratably with each of the other undersigned entitled to reimbursement or contribution from any other undersigned as set forth in this paragraph) to any security interest that may then be held by the Collateral Agent upon any Collateral securing or purporting to secure any of the Liabilities. For purposes of (a)(ii) above, , the fair share of each undersigned as to any unreimbursed payment shall be determined based on an equitable apportionment of such unreimbursed payment among all of the undersigned (other than the undersigned whose primary obligations were so guaranteed by each of the other undersigned) based on the relative value of their assets and any other equitable considerations deemed appropriate by the court. Any right of subrogation of any of the undersigned shall be enforceable solely after such time as this Guaranty shall have been terminated as to all of the undersigned and the Lender Parties shall have received final payment in cash of the full amount of all Liabilities and solely against each of the undersigned, and not against the Lender Parties, and neither the Collateral Agent nor any other Lender Party shall have any duty whatsoever to warrant, ensure or protect any such right of subrogation or to obtain, perfect, maintain, hold, enforce or retain any Collateral securing or purporting to secure any of the Liabilities for any purpose related to any such right of subrogation. All rights and claims arising under this paragraph or based upon or relating to any other right of reimbursement, indemnification, contribution or subrogation that may at any time arise or exist in favor of any of the undersigned as to any payment on account of either (x) the Liabilities or (y) any other obligation that is secured by any Collateral that also secures or purports to secure any of the Liabilities, in each case made by it or received or collected from its property shall be fully subordinated to the Liabilities in all respects prior to such time as this Guaranty shall have been terminated as to all of the undersigned and the Lender Parties shall have received final payment in cash of the full amount of all Liabilities. Until such time as this Guaranty shall have been terminated as to all of the undersigned and the Lender Parties shall have received final payment in cash of the full amount of all Liabilities, none of the undersigned may demand or receive any collateral security, payment or distribution whatsoever (whether in cash, property or securities or otherwise) on account of any such right or claim. If any such payment or distribution is made or becomes available to any of the undersigned in any bankruptcy case, receivership, or insolvency or liquidation proceeding, such payment or distribution shall be delivered by the person making such payment or distribution directly to the Collateral Agent, for application to the payment of the Liabilities. If any such payment or distribution is received by any of the undersigned, it shall be held by such undersigned in trust, as trustee of an express trust for the benefit of the Lender Parties, and shall forthwith be transferred and delivered by such undersigned to the Collateral Agent, in the exact form received and, if necessary, duly endorsed.

4

Each of the undersigned hereby expressly waives: (a) notice of the acceptance by any Lender Party of this Guaranty, (b) notice of the existence or creation or non-payment of all or any of the Liabilities, (c) presentment, demand, notice of dishonor, protest, and all other notices whatsoever, and (d) all diligence in collection or protection of or realization upon any Liabilities or any security for or guaranty of any Liabilities.

The creation or existence from time to time of additional Liabilities to any Lender Party is hereby authorized, without notice to any of the undersigned, and shall in no way affect or impair the rights of any Lender Party or the obligations of any of the undersigned under this Guaranty.

Subject to the provisions of the Loan Agreement, any Lender Party may from time to time, without notice to any of the undersigned, assign or transfer any of the Liabilities or any interest therein; and, notwithstanding any such assignment or transfer or any subsequent permitted assignment or permitted transfer thereof, such Liabilities shall be and remain Liabilities for purposes of this Guaranty, and each and every immediate and successive permitted assignee or permitted transferee of any of the Liabilities or of any interest therein shall, to the extent of the interest of such assignee or transferee in the Liabilities, be entitled to the benefits of this Guaranty to the same extent as if such assignee or transferee were an original Lender Party.

No delay on the part of any Lender Party in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by any Lender Party of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy, nor shall any modification or waiver of any provision of this Guaranty be binding upon any Lender Party except as expressly set forth in a writing duly signed and delivered on behalf of the Administrative Agent. No action of any Lender Party permitted hereunder shall in any way affect or impair the rights of any Lender Party or the obligations of any of the undersigned under this Guaranty. For purposes of this Guaranty, Liabilities shall include all obligations of the Borrower to any Lender Party arising under or in connection with any Loan Document, notwithstanding any right or power of the Borrower or anyone else to assert any claim or defense as to the invalidity or unenforceability of any obligation, and no such claim or defense shall affect or impair the obligations of any of the undersigned hereunder.

Pursuant to the Loan Agreement, (a) this Guaranty has been delivered to the Administrative Agent and (b) the Administrative Agent has been authorized to enforce this Guaranty on behalf of the Lender Parties. All payments by any of the undersigned pursuant to this Guaranty shall be made to the Administrative Agent (and any amount received by the Administrative Agent for the account of a Lender Party shall, subject to the other provisions of this Guaranty, be deemed received by such Lender Party upon receipt by the Administrative Agent) at such office or account of the Administrative Agent as the Administrative Agent may designate from time to time, in lawful money of the United States of America and in immediately available funds without setoff, recoupment, deduction, defense or counterclaim and free and clear of, and, except as required by applicable law, without deduction or withholding for or on account of, any Taxes, but excluding Taxes imposed on or measured by the Administrative Agent’s net income by the jurisdiction of the Administrative Agent’s organization, the United States of America, the State or City of New York or any taxing authority thereof. If, under

5

applicable law, any such Taxes are required to be deducted or withheld from any such payment, each of the undersigned will pay additional interest or will make additional payments in such amounts as may be necessary so that the net amount received by the Administrative Agent, after withholding or deduction therefor and for any Taxes and other taxes on such additional interest or amounts, will be equal to the amount provided for herein. Each of the undersigned agrees to furnish promptly to the Administrative Agent official receipts evidencing payment of any Taxes so withheld or deducted. Each of the undersigned hereby agrees to indemnify the Administrative Agent for, and to hold the Administrative Agent harmless against, the full amount of Taxes imposed on or paid by the Administrative Agent, and any liability (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto. The indemnity by each of the undersigned provided for in this paragraph shall apply and be made whether or not the Taxes for which indemnification hereunder is sought have been correctly or legally asserted. Amounts payable by each of the undersigned under the indemnity set forth in this paragraph shall be paid within ten (10) days from the date on which the Administrative Agent makes written demand therefor. Determinations by the Administrative Agent pursuant to this paragraph shall be conclusive absent manifest error, and the provisions of this paragraph shall survive termination of this Guaranty.

Each of the undersigned acknowledges and agrees that it has the sole responsibility for, and has adequate means of, obtaining from the Borrower such information concerning the financial condition, business and operations of the Borrower as such undersigned requires, and that the Lender Parties have no duty, and such undersigned is not relying on the Lender Parties at any time, to disclose to such undersigned any information relating to the business, operations or financial condition of the Borrower.

Any other Person may become a guarantor hereunder and become bound by the terms and conditions of this Guaranty, in each case effective as of the date set forth in the applicable Joinder, by executing and delivering to the Administrative Agent a Joinder to Guaranty substantially in the form attached hereto as Exhibit “A” (a “Joinder”).

This Guaranty shall be binding upon each of the undersigned and their respective successors and assigns, and to the extent that any of the undersigned is a partnership, corporation, limited liability company or other entity, all references herein to any of the undersigned shall be deemed to include any successor or successors, whether immediate or remote, to such undersigned. The term “undersigned” as used herein shall mean all parties executing this Guaranty and each of them, and all such parties shall, to the extent set forth herein, be jointly and severally obligated hereunder.

THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO CONFLICTS OF LAW PROVISIONS THEREOF). Whenever possible each provision of this Guaranty shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Guaranty shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Guaranty.

6

Consistent with the foregoing, and notwithstanding any other provision of this Guaranty to the contrary, in the event that any action or proceeding is brought in whatever form and in whatever forum seeking to invalidate any Guarantor’s obligations under this Guaranty under any fraudulent conveyance theory, fraudulent transfer theory, or similar avoidance theory, whether under state or federal law, such Guarantor (the “Affected Guarantor”), automatically and without any further action being required of such Affected Guarantor or any Lender Party, shall be liable under this Guaranty only for an amount equal to the maximum amount of liability that could have been incurred under applicable law by such Affected Guarantor under any guaranty of the Liabilities (or any portion thereof) at the time of the execution and delivery of this Guaranty (or, if such date is determined not to be the appropriate date for determining the enforceability of such Affected Guarantor’s obligations hereunder for fraudulent conveyance or transfer (or similar avoidance) purposes, on the date determined to be so appropriate) without rendering such a hypothetical guaranty voidable under applicable law relating to fraudulent conveyance, fraudulent transfer, or any other grounds for avoidance (such highest amount determined hereunder being any such Affected Guarantor’s “Maximum Guaranty Amount”), and not for any greater amount, as if the stated amount of this Guaranty as to such Affected Guarantor had instead been the Maximum Guaranty Amount. This paragraph is intended solely to preserve the rights of the Lender Parties under this Guaranty to the maximum extent not subject to avoidance under applicable law, and neither any Affected Guarantor nor any other person or entity shall have any right or claim under this paragraph with respect to the limitation described in this Guaranty, except to the extent necessary so that the obligations of any Affected Guarantor under this Guaranty shall not be rendered voidable under applicable law. Without limiting the generality of the foregoing, the determination of a Maximum Guaranty Amount for any Affected Guarantor pursuant to the provisions of the second preceding sentence of this paragraph shall not in any manner reduce or otherwise affect the obligations of any other Guarantor (including any other Affected Guarantor) under the provisions of this Guaranty.

This Guaranty may be executed in any number of counterparts (including via facsimile or in a .pdf or similar file) and by the different parties hereto on separate counterparts and each such counterpart shall be deemed to be an original, but all such counterparts shall together constitute one and the same Guaranty.

Other than automatic modifications related to the addition of a party hereto pursuant to a Joinder, no amendment, modification or waiver of, or consent with respect to, any provision of this Guaranty shall be effective unless the same shall be in writing and signed and delivered by the Administrative Agent, and then such amendment, modification, waiver or consent shall be effective only in the specific instance and for the specific purpose for which it was given.

Unless otherwise agreed by the Lender Parties and each of the undersigned in writing, this Guaranty is not intended to supersede or otherwise affect any other guaranty now or hereafter given by such undersigned for the benefit of the Lender Parties or any term or provision thereof.

The obligations of each of the undersigned under this Guaranty are secured pursuant to the Collateral Documents (as amended, restated, supplemented or otherwise modified from time to time) and may be secured by one or more other agreements (including one or more pledge agreements, mortgages, deeds of trust or other similar documents).

7

ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS GUARANTY, SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK; PROVIDED THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE ADMINISTRATIVE AGENT’S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND. EACH OF THE UNDERSIGNED AND THE ADMINISTRATIVE AGENT HEREBY EXPRESSLY AND IRREVOCABLY (A) SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE; (B) CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID TO THE ADDRESS SET FORTH BENEATH ITS NAME ON THE SIGNATURE PAGES HERETO (OR SUCH OTHER ADDRESS AS IT SHALL HAVE SPECIFIED IN WRITING TO THE OTHER PARTIES AS ITS ADDRESS FOR NOTICE HEREUNDER) OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK; AND (C) WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

EACH OF THE UNDERSIGNED, AND (BY ACCEPTING THE BENEFITS HEREOF) EACH LENDER PARTY, HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS GUARANTY OR ANY OTHER LOAN DOCUMENT AND ANY AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR ARISING FROM ANY BANKING RELATIONSHIP EXISTING IN CONNECTION WITH ANY OF THE FOREGOING, AND AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. EACH OF THE UNDERSIGNED ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THE FOREGOING WAIVER AND THAT SUCH WAIVER IS A MATERIAL INDUCEMENT FOR THE LENDER PARTIES ENTERING INTO THIS GUARANTY AND THE OTHER LOAN DOCUMENTS.
