                       ----------------------------------



$___________                                                    January __, 2005
New York, New York


         FOR VALUE RECEIVED, the undersigned, XETHANOL BIOFUELS, LLC (the
"Maker"), hereby promises to pay to the order of _________________ (the "Payee")
the principal sum of ___________ ($________) Dollars, together with interest as
hereinafter provided. All payments of principal and/or interest shall be paid as
set forth below, and, except as hereinafter provided, each such payment shall be
made in lawful money of the United States of America.


         1.     Payments of Principal and Interest.
                -----------------------------------

                (a)   The entire principal balance of this Note, together with
all unpaid accrued interest hereunder, shall be due and payable on January __,
2012.


                (b)   This Note shall bear interest, payable semi-annually on or
before June 30 and December 31 of each year commencing June 30, 2005, in an
amount equal to the greater of (i) 5% of the gross revenues (determined in
accordance with generally accepted accounting principles consistently applied)
of the Maker from the sale of ethanol and wet distillers grain at the Maker's
Blairstown, Iowa facility, during the two calendar quarters prior to the subject
June 30 and December 31, but not before the date hereof (each, an "Interest
Period," subject to appropriate pro-ration for the first Interest Period if this
Note is originally issued after January 1, 2005), or (ii) 10% per annum on the
daily outstanding principal amount of this Note. The minimum interest of 10% per
annum shall be paid on or before June 30 and December 31, and if the amount
calculated pursuant to subclause (i) is, upon calculation thereof, greater than
the interest payment, the excess amount shall be paid within 30 days following
such calculation.


                (c)   If and to the extent that any interest payment as
aforesaid shall be deemed in excess of the amount of interest legally permitted
to be charged hereon under applicable law, or shall otherwise be adjudged to be
in violation of any applicable law, then the amount of such excess shall not be
deemed to be interest and shall instead be treated as a royalty on the security
hereof.


         2.     Call and Exchange Option.
                -------------------------

                (a)   The Maker may, at its option, on and after January ___,
2008, upon not less than thirty (30) days prior written notice given to the
Payee (a "Call Notice"), require the Payee to surrender this Note in exchange
for an amount equal to the sum of (i) 130% of the then-outstanding principal
balance of this Note, plus (ii) all accrued but unpaid interest hereunder.

                (b)   Within thirty (30) days after the Payee's receipt of a
Call Notice, the Payee shall, by written election delivered to the Maker, elect
either (i) to accept, in exchange for this Note, all (but not part) of the
amount described in paragraph 2(a) above, or (ii) to convert this Note in
accordance with the provisions of Section 6 below in lieu of the exchange in
respect of the amount to be converted. The Payee shall surrender this Note for
cancellation on the date fixed for exchange, against delivery of the amount to
be paid or certificates for Conversion Shares (as such term is defined in
Section 6 below).

arrangement with creditors or to take advantage of any bankruptcy,
reorganization, insolvency, readjustment of debt, dissolution or liquidation law
or statute, or an answer admitting the material allegations of a petition filed
against it in any proceeding under any such law, or (vi) take any action in
furtherance of or for the purpose of effecting any of the foregoing; or

                (c)   if any order, judgment or decree shall be entered, without
the application, approval or consent of the Maker, by any court of competent
jurisdiction, approving a petition seeking reorganization of the Maker or
appointing a receiver, trustee, custodian, liquidator or other such official of
the Maker, or of all or a substantial part of its assets, and such order,
judgment or decree shall continue unstayed and in effect for any period of sixty
(60) days; or

                (d)   if the Maker hereafter pays any dividends (other than
dividends paid solely in the form of capital stock of the Maker) on any of its
capital stock, or hereafter effects any redemption of any of its capital stock,
or hereafter lends any funds to any of its officers, directors or equity holders
(other than loans or advances for business purposes in the ordinary course of
business), in any case, unless the Maker has, at the time of and after giving
effect to such dividend, redemption payment or loan, an unrestricted cash
balance of $1,000,000 or more; or

connection with the original issuance of this Note; or

                (g)   any dissolution, liquidation or winding-up of the Maker
(provided that any merger or consolidation involving the Maker, or any sale of
assets by the Maker which does not have the practical effect of liquidating or
winding-up the Maker's business, shall not be deemed a dissolution, liquidation
or winding-up for purposes of this Section 3(g)).

                  4. Remedies on Default.
                     -------------------

                  If any Event of Default shall occur and be continuing, then
(a) if such event is of the type described in Section 3(b) or 3(c) above, this
Note shall automatically become due and payable, or (b) in any other such event,
and at any time thereafter, if such event shall then be continuing, the holder
of this Note may, by written notice to the Maker, declare


                                       2
<PAGE>


due and payable the principal of, and interest on, this Note, whereupon the same
shall be immediately due and payable. In the event that this Note becomes or is
declared due and payable prior to its stated maturity, the same shall become due
and payable without presentment, demand, protest or other notice of any kind,
all of which are hereby expressly waived.

         5.     Security.
                --------

         This Note, and the Maker's obligations hereunder, are secured by
certain land, buildings and site improvements, mechanical and process equipment
and personal property as provided in the Security Agreement of even date
herewith by and between the Maker and Payee.

         6.     Conversion.
                ----------

                (a)   The Payee shall have the right, exercisable at any time to
convert all (but not part) of the principal and/or unpaid accrued interest of
this Note into fully paid and non-assessable shares of common Stock ("Common
Stock") of Xethanol Corporation or its public successor (the "Parent"), with the
Common Stock being valued for purposes hereof at $4.00 per share (the
"Conversion Price"). In order to exercise this conversion option, the Payee
shall give written notice thereof to the Maker setting forth the outstanding
amount of this Note to be converted and the Payee's calculation of the number of
shares of Common Stock issuable upon such conversion (the "Conversion Shares"),
and such notice shall be accompanied by the original of this Note.

                (b)   No fractional shares will be issued upon any conversion of
this Note, but if the conversion results in a fraction, the fair market value of
such fractional share of Common Stock (which shall be the closing price of such
shares on the exchange or market on which the Common Stock is then traded) will
be paid by the Maker in cash. This right of conversion shall cease upon payment
in full of all principal and interest and other amounts due in respect of this
Note. The Conversion Price of the Conversion Shares shall be appropriately
adjusted in the event of a stock split, stock dividend or similar transaction.

                (c)   The Maker shall deliver or cause to be delivered to the
Payee a certificate or certificates for the applicable number of Conversion
Shares as soon as practicable after surrender of this Note for conversion, but
the person or persons to whom such certificates are issuable shall be considered
the holder of record of the Conversion Shares from the time this Note is
surrendered for conversion. Except as described above, this Note is not
otherwise convertible into shares of Common Stock.

                (d)   If, at the time of issuance of the Conversion Shares, no
registration statement is in effect with respect to such shares under applicable
provisions of the United States Securities Act of 1933, as amended, the Maker
and/or the Parent may at its election require that the Payee provide the Maker
and/or the Parent with written confirmation of the Payee's investment intent and
that any stock certificate delivered to the Payee upon conversion of this Note
shall bear a legend reading substantially as follows:

         THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE U.S. SECURITIES ACT OF 1933, AND MAY NOT BE SOLD,
         TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN
         EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933 OR AN
         OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THIS CERTIFICATE THAT
         REGISTRATION IS NOT REQUIRED UNDER SAID ACT.

                (e)   The Conversion Shares will be afforded the same
registration rights as all shares of Common Stock sold by Parent in the private
offering to be consummated on or about the date hereof.

waives diligence, demand, presentment for payment, protest, dishonor,
nonpayment, default, and notice of any and all of the foregoing.

         8.     Amendments.
                ----------

         This Note may not be changed orally, but only by an agreement in
writing signed by the party against whom enforcement of any waiver, change,
modification or discharge is sought.

         9.     Governing Law; Waiver of Jury Trial.
                -----------------------------------

         This Note shall be deemed to be a contract made under the laws of the
State of New York and shall be governed by, and construed in accordance with,
the laws of the State of New York. THE MAKER HEREBY WAIVES THE RIGHT TO TRIAL BY
JURY IN ANY ACTION OR PROCEEDING FOR THE ENFORCEMENT OR COLLECTION OF THIS NOTE.

         10.    Collection Costs.
                ----------------

         In the event that the Payee shall, after the occurrence and during the
continuance of an Event of Default, turn this Note over to an attorney for
collection, the Maker shall further be obligated to the Payee for the Payee's
reasonable attorneys' fees and expenses incurred in connection with such
collection.

         11. Transfer.
             --------

         This Note shall be non-negotiable and non-transferable except to
entities controlled by, controlling or under common control with the Payee, as
to whom this Note may be assigned without the Maker's consent.
