Item 1.01. Entry into a Material Definitive Agreement.

On October 5, 2007, Xethanol Corporation (“Xethanol”), the registrant, entered into a Stock Purchase and Termination Agreement (the “Agreement”) with H2Diesel Holdings, Inc. (“Holdings”), and Holdings’ wholly-owned subsidiary, H2Diesel, Inc. On signing the Agreement, Holdings paid Xethanol a $250,000 non-refundable deposit that will apply towards the purchase price described below. Xethanol and H2Diesel, Inc. are parties to an Amended and Restated Sublicense Agreement dated June 15, 2006, a Technology Access Agreement dated June 15, 2006 and a Letter Agreement regarding registration rights dated October 16, 2006. Xethanol currently owns 5,850,000 shares of common stock, par value of $0.001 per share, of Holdings. The common stock of Holdings is quoted on the OTC Bulletin Board under the trading symbol HTWO.OB. According to Yahoo Finance, the closing price of the common stock of Holdings on October 5, 2007 was $7.00 per share, and the average daily trading volume over the previous three months was approximately 9,200 shares.

Under the Agreement, which provides for a future closing as described below, Xethanol agreed to sell to Holdings 5,460,000 shares of the common stock of Holdings, or approximately 31.6% of Holdings’ outstanding common stock. The purchase price is $7.0 million, or approximately $1.28 per share. In addition, the agreements described in the previous paragraph will be terminated at the closing, and a $50,000 loan from Xethanol to H2Diesel will be deemed to be satisfied and cancelled. The closing is conditioned on the closing of a transaction in which Holdings obtains a minimum of $10,000,000 of new financing, although Holdings may waive this condition in its sole discretion. (Xethanol will retain the remaining 390,000 shares of Holdings’ common stock that it now owns.)

If the closing does not occur on or before November 9, 2007, or a later date as the parties may agree in writing, each party shall have an independent right to terminate the Agreement on 10 calendar days’ written notice to the other party. Neither party will incur any obligation to the other party as a result of the termination, unless the termination results from a failure to close arising from a breach by a party of its obligations under the Agreement, in which case the non-breaching party will be entitled to pursue remedies at law or equity. The failure of Holdings to obtain new financing will not be a breach of the Agreement. If the Agreement is terminated other than as a result of a breach by Xethanol of its obligations under the Agreement, Xethanol will retain the non-refundable deposit of $250,000.

The board of directors of Xethanol unanimously approved the transaction. In its deliberation, the board took into account a fairness opinion from Taylor Consulting Group, Inc., Atlanta, Georgia, to the effect that the terms of the transaction were fair and reasonable from a financial point of view to Xethanol and to its shareholders.

Xethanol recommends that investors read the Agreement carefully. A copy of the Agreement is attached to this report as Exhibit 10.1 and is incorporated into this report by this reference.
