Plan of Merger

Great Lakes Cooperative and Green Plains Renewable Energy, Inc.

Dear (INDIVIDUAL NAME),

On August 15, 2007, the Great Lakes Cooperative (GLC) board of directors adopted a Plan of Merger with Green Plains Renewable Energy, Inc., an ethanol production company.

The proposed merger combines GLC and Green Plains to create a stronger, more competitive company.  GLC members will receive liquidity and the opportunity to benefit from a vertically-integrated operation.

The merger requires the approval of GLC voting members.(SHAREHOLDER NAME), as a GLC voting member, we ask you to carefully consider all the information contained in this packet.  Your participation in this election is critically important.

Proceeds from Merger

If approved, GLC members as group will receive approximately $12.5 million in cash and 551,065 shares of Green Plains’ common stock.  Green Plains’ common stock is listed under the stock symbol “GPRE” on The NASDAQ Capital Market and the American Stock Exchange. After the merger, GLC members will own approximately 7.1% of GPRE stock.  

(SHAREHOLDER NAME), based on your GLC interests, your share of the distribution of proceeds is as follows:

Distribution of Proceeds

Cash	(CASH AMOUNT)
GPRE Common Stock Shares	(# GPRE SHARES)
% Interest in the Escrow Account	(ESCROW % AMOUNT)

Members with GLC stock with a par value of less than $1,000 receive cash only.  Members with GLC stock with a par value of more than $1,000 receive a combination of cash and stock. Additionally, GLC members will receive an interest in an Escrow Account that will be established to hold GLC’s investments in regional cooperatives. Green Plains’ shareholders receive no consideration in connection with the proposed merger. The formula for conversion and distribution of the proceeds is contained in the Registration Statement at pages 43-44.

Plan of Merger

The enclosed Registration Statement provides you with detailed information about Green Plains, GLC and the Plan of Merger.  If approved, GLC will become a wholly-owned subsidiary of Green Plains.  It will continue to operate as a full-service business partner with area agricultural producers.   Details of the combined organization are contained in the Registration Statement at page 37.

The GLC board is recommending this merger with Green Plains and we believe that the merger will result in a number of benefits and that the combined organization will capture the efficiencies of vertical integration.  The combination would match GLC’s grain marketing and handling strengths with Green Plains’ feedstock procurement requirements.  Additionally, we believe that the long-term opportunities to jointly develop innovations and efficiencies in the production of grain feedstock for the ethanol industry will benefit our members.

Green Plains’ current board and management team will lead the combined organization. It is anticipated that most, if not all, of GLC’s employees will remain as employees of the combined organization after the combination.

Information Meetings

Several information meetings are scheduled to provide GLC members with additional information.  GLC and Green Plains staff will be available to answer questions and address concerns.
