Exhibit A

PROMISSORY NOTE


$[ ]		Dated as of: , 2012

For value received, GREEN PLAINS RENEWABLE ENERGY, INC., an Iowa corporation (the “Debtor”), agrees to pay to the order of GREENSTAR INVESTMENTS LLC, a Delaware limited liability company (“Greenstar”), the principal sum of [ ]and [ ]/100 U.S. Dollars ($[ ]) on the first anniversary of the date hereof (the “Due Date”), together with interest thereon as specified herein.

This Promissory Note (this “Note”) is delivered pursuant to Section 4(c) of that certain Stock Repurchase Agreement by and among Greenstar, Greenstar North America Holdings, Inc., a Delaware corporation (“GNAH”), and Debtor (the “Repurchase Agreement”) and Debtor’s obligations hereunder are secured by that certain Assignment and Pledge of Stock and LLC Interest dated on or about the date hereof (“Assignment”) executed by Debtor in favor of Greenstar pledging 2,700,000 shares of treasury stock of Debtor and Debtor’s interest in Green Plains Shenandoah LLC (“Shenandoah”). Greenstar is not required, but may choose at its sole discretion, to rely on any security granted to it for the payment of this Promissory Note in the case of default, but may proceed directly against the Debtor.

Interest shall accrue daily on the outstanding principal amount of this Note (and on any past-due interest payment) at a rate of five percent (5.0%) per annum, and shall be paid quarterly in arrears on the last day of each calendar quarter. If any payment of principal or interest on this Note is due on a day that is not a business day, such payment shall be due on the next succeeding business day, and such extension of time shall be taken into account in calculating the amount of interest payable under this Note. Interest shall be calculated on the basis of a year of 365 days and charged for the actual number of days elapsed. The date on which any interest payment becomes due is referred to herein as an “Interest Payment Date”.

In addition to exercising any rights Greenstar has been granted by Debtor under the Assignment, Debtor, as evidenced by its signature below, authorizes Greenstar to seek any other legal means of collection if Debtor is in default of this Note.

If (a) Debtor fails to pay the principal and accrued interest on this Note in full on or before the applicable Due Date or Interest Payment Date, or (b) pursuant to or within the meaning of the United States Bankruptcy Code or any other federal or state law relating to insolvency or relief of debtors, Debtor or Shenandoah shall (i) commence a voluntary case or proceeding; (ii) consent to the entry of an order for relief against it in an involuntary case; (iii) consent to the appointment of a trustee, receiver, assignee, liquidator or similar official; (iv) make an assignment for the benefit of its creditors; or (v) admit in writing its inability to pay its debts as they become due, (each, an “Event of Default”) then this Note and all of the obligations hereunder shall become due immediately. Debtor shall notify Greenstar in writing of the occurrence of any Event of Default within five (5) days after Debtor acquires knowledge of such occurrence.

The whole or part of the principal due hereunder may be prepaid at any time without penalty provided there exists at the time of prepayment no default hereunder. Payments shall be applied first to the payment of any fees, expenses or past due amounts owing by the Debtor to Greenstar, second to interest accrued on the unpaid principal balance, if applicable, and third to the principal balance.

Except as expressly set forth herein, the Debtor hereby waives presentment, demand, notice, protest and all other demands and notices in connection with the delivery, acceptance, performance or enforcement of this Note. If an Event of Default occurs, Greenstar shall be entitled to recover from Debtor all reasonable costs and expenses of collection of Greenstar and its affiliates, including court costs and reasonable attorney’s fees, in the event collection procedures are commenced by Greenstar in accordance with the terms of this Note or the Assignment after any amount hereunder becomes due and payable.

If any provision of this Note is deemed by any court, having jurisdiction thereon to be invalid or unenforceable, the balance of this Note shall remain in effect; if any provision of this Note is deemed by any such court to be unenforceable because such provision is too broad in scope, such provision shall be construed to be limited in scope to the extent such court shall deem necessary to make it enforceable; and if any provision is deemed inapplicable by any such court to any person or circumstances, it shall nevertheless be construed to apply to all other persons and circumstances.

No delay or omission on the part of Greenstar in exercising any right hereunder shall operate as a waiver of such right or of any other right under this Note. No waiver of any right shall be effective unless in writing and signed by Greenstar nor shall a waiver on one occasion be construed as a bar to or waiver of any such right on any future occasion.

This Note shall only be amended if such amendment is agreed to by both Debtor and Greenstar, in writing, and executed by both Debtor and Greenstar. Any notice hereunder shall be given in accordance with Section 12(d) of the Repurchase Agreement.

This Note shall be governed by and construed in accordance with the laws of the State of New York, without regard to its rules of conflict of laws.

Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

Grantor hereby waives any claims against Secured Party by reason of the fact that the price at which any Collateral may have been sold at such a private sale, if commercially reasonable, was less than the price which might have been obtained at a public sale, even if Secured Party accepts the first offer received and does not offer such Collateral to more than one of offeree.

(e) Grantor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification.

Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. Assuming that such sales are made in compliance with federal and state securities laws, Secured Party shall incur no liability as a result of the sale of the Collateral, or any part thereof, at any public or private sale.

(g) Grantor recognizes that Secured Party may elect in its sole discretion to sell all or a part of the Collateral to one or more purchasers in privately negotiated transactions in which the purchasers will be obligated to agree, among other things, to acquire the Collateral for their own account, for investment and not with a view to the distribution or resale thereof. Grantor acknowledges that any such private sales may be at prices and on terms less favorable than those obtainable through a public sale (including, without limitation, a public offering made pursuant to a registration statement under the Securities Act of 1933, as amended (the “Securities Act”)), and Grantor and Secured Party agree that such private sales shall be made in a commercially reasonable manner and that Secured Party has no obligation to engage in public sales and no obligation to delay sale of any Collateral to permit the issuer thereof to register the Collateral for a form of public sale requiring registration under the Securities Act.
