     SECTION 2.1 ANNUAL MEETING: The annual meeting of the shareholders shall be
held on the third Wednesday in the month of January in each year, beginning with
the year 2003 at the hour designated in the notice of said meeting, for the
purpose of electing directors and for the transaction of such other business as
may come before the meeting. If the day fixed for the annual meeting shall be a
legal holiday in the State of South Dakota, such meeting shall be held on the

adjournment thereof, the Board of Directors shall cause the election to be held
at a special meeting of the shareholders as soon thereafter as conveniently may
be.

     SECTION 2.2 SPECIAL MEETINGS: Special meetings of the shareholders, for any
purpose or purposes, unless otherwise prescribed by statute, may be called by
the Chairman of the Board, the President or by the Board of Directors, and shall

holders of not less than one-tenth of all the outstanding shares of the
corporation entitled to vote at the meeting.



     SECTION 2.3 PLACE OF MEETING: The Board of Directors may designate any
place, either within or without the State of South Dakota, as the place of
meeting for any annual meeting or for any special meeting called by the Board of
Directors. A waiver of notice signed by all shareholders entitled to vote at a
meeting may designate any place, either within or without the State of South
Dakota, as the place for the holding of such meeting. If no designation is made,
or if a special meeting be otherwise called, the place of meeting shall be the
registered office of the corporation in the State of South Dakota.

     SECTION 2.4 NOTICE OF MEETING: Except for the increase of stock and
indebtedness of the corporation when sixty (60) days' notice is required by
Article XVII, Section 8, of the South Dakota Constitution, written or printed
notice stating the place, day and hour of the meeting and, in case of a special
meeting, the purpose or purposes for which the meeting is called, shall be
delivered not less than ten (10) nor more than fifty (50) days before the date
of the meeting, either personally or by mail, by or at the direction of the
Chairman of the Board, the President, or the Secretary, or the officer or
persons calling the meeting, to each shareholder of record entitled to vote at
such meeting. If mailed, such notice shall be deemed to be delivered when
deposited in the United States mail, addressed to the shareholder at the
shareholder's address as it appears on the stock transfer books of the
corporation, with postage thereon prepaid.

     SECTION 2.5 CLOSING OF TRANSFER BOOKS OR FIXING OF RECORD DATE: For the
purpose of determining shareholders entitled to notice of or to vote at any
meeting of shareholders or any adjournment thereof, or shareholders entitled to
receive payment of any dividend, or in order to make a determination of
shareholders for any other proper purpose, the Board of Directors of the
corporation may provide that the stock transfer books shall be closed for a
stated period but not to exceed, in any case, fifty (50) days. If the stock
transfer books shall be closed for the purpose of determining shareholders
entitled to notice of or to vote at a meeting of shareholders, such books shall
be closed for at least ten (10) days immediately preceding such meeting. In lieu
of closing the stock transfer books, the Board of Directors may fix in advance a
date as the record date for any such determination of shareholders, such date in
any case to be not more than fifty (50) days and, in case of a meeting of
shareholders, not less than ten (10) days prior to the date on which the
particular action, requiring such determination of shareholders, is to be taken.
If the stock transfer books are not closed and no record date is fixed for the
determination of shareholders entitled to receive notice of or to vote at a
meeting of shareholders, or shareholders entitled to receive payment of a
dividend, the close of business on the day on which notice of the meeting is
mailed or the date on which the resolution of the Board of Directors declaring
such dividend is adopted, as the case may be, shall be the record date for such
determination of shareholders. When a determination of shareholders entitled to
vote at any meeting of shareholders has been made as provided in this Section,
such determination shall apply to any adjournment thereof.

     SECTION 2.6 VOTING LISTS: The officer or agent having charge of the stock
transfer books for shares of the corporation shall make, at least ten (10) days
before each meeting of shareholders, a complete list of the shareholders
entitled to vote at such a meeting, or any adjournment thereof, arranged in
alphabetical order, with the address of and the number of shares held by each,
which list, for a period of ten (10) days prior to such meeting, shall be kept
on file at the registered office of the corporation and shall be subject to
inspection by any shareholder at any time during usual business hours. Such list
shall also be produced and kept open at the time


                                       2



and place and for the whole of the meeting and shall be prima facie evidence as
to who are the shareholders entitled to examine such list or transfer books or
to vote at any meeting of shareholders. Failure to comply with the requirements
of this Section shall not affect the validity of any action taken at such
meeting.

     SECTION 2.7 QUORUM: A majority of the outstanding shares of the corporation
entitled to vote, represented in person or by proxy, shall constitute a quorum
at a meeting of shareholders. If less than a majority of the outstanding shares
are represented at a meeting, a majority of the shares so represented may
adjourn the meeting from time to time without further notice. At such adjourned
meeting at which a quorum shall be present or represented, any business may be
transacted which might have been transacted at the meeting as originally
notified. The shareholders present at a duly organized meeting may continue to
transact business until adjournment notwithstanding the withdrawal of enough
shareholders to leave less than a quorum.

     SECTION 2.8 PROXIES: At all meetings of shareholders, a shareholder may
vote by proxy executed in writing by the shareholder or by the shareholder's
duly authorized attorney-in-fact. Such proxy shall be filed with the Secretary
of the corporation before or at the time of the meeting. No proxy shall be valid
after eleven (11) months from the date of its execution, unless otherwise
provided in the proxy.

     SECTION 2.9 VOTING OF SHARES: Subject to the provisions of Section 2.11,
and except to the extent that voting rights of the shares of any class or
classes are limited or denied by the Articles of Incorporation, each outstanding
share entitled to vote shall be entitled to one vote upon each matter submitted
to a vote at a meeting of shareholders.

     SECTION 2.10 VOTING OF SHARES BY CERTAIN HOLDERS: Shares standing in the
name of another corporation may be voted by such officer, agent or proxy as the
bylaws of such corporation may prescribe, or, in the absence of such provision,
as the board of directors of such other corporation may determine.

     Shares held by an administrator, executor, guardian or conservator may be
voted by him, her or it, either in person or by proxy, without a transfer of
such shares into his, her or its name. Shares standing in the name of a trustee
may be voted by such trustee, either in person or by proxy, but no trustee shall
be entitled to vote shares held by such trustee without a transfer of such
shares into such trustee's name.

     Shares standing in the name of a receiver may be voted by such receiver,
and shares held by or under the control of a receiver may be voted by such
receiver without the transfer thereof into such receiver's name if authority so
to do be contained in an appropriate order of the court by which such receiver
was appointed.

     A shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledgee, and
thereafter the pledgee shall be entitled to vote the shares so transferred.

     Shares of its own stock belonging to the corporation or held by it in a
fiduciary capacity shall not be voted, directly or indirectly, at any meeting
and shall not be counted in determining the total number of outstanding shares
at any given time.

     SECTION 2.11 CUMULATIVE VOTING: At each election for directors every
shareholder entitled to vote at such election shall have the right to vote, in
person or by proxy, the number of shares owned by such shareholder for as many
persons as there are directors to be elected and for whose election such
shareholder has a right to vote, or to cumulate such shareholder's votes by
giving one candidate as many votes as the number of such directors multiplied by
the number of shares owned by such shareholder shall equal, or by distributing
such votes on the same principle among any number of candidates.

     SECTION 2.12 WAIVER OF NOTICE: Whenever any notice is required to be given
to any shareholder under the Articles of Incorporation, these Bylaws or any
provision of law, a waiver thereof, signed by the person entitled to such
notice, whether before or after the time stated therein, shall be equivalent to
the giving of such notice.

     SECTION 2.13 INFORMAL ACTION BY SHAREHOLDERS: Any action required to be
taken at a meeting of the shareholders, or any other action which may be taken
at a meeting of the shareholders, may be taken without a meeting if a consent in
writing, setting forth the action so taken, shall be signed by all of the
shareholders entitled to vote with respect to the subject matter thereof.

                                    SECTION 3

                               BOARD OF DIRECTORS

     SECTION 3.1 GENERAL POWERS: The business and affairs of the corporation
shall be managed by its Board of Directors.

     SECTION 3.2 NUMBER, TENURE AND QUALIFICATIONS: The exact number of
directors of the corporation may, within the limits of not less than one (1) nor
more than five (5), be fixed and increased or decreased from time to time by
resolution of the Board of Directors. Each director shall hold office until the
next annual meeting of shareholders and until his or her successor shall have
been elected and qualified. Directors need not be shareholders of the
corporation, but shall have knowledge and experience in the ethanol industry. A
director may resign at any time by filing his or her resignation with the
Secretary of the corporation.

     SECTION 3.3 REGULAR MEETINGS: A regular meeting of the Board of Directors
shall be held without other notice than this Bylaw immediately after, and at the
same place as, the annual meeting of shareholders. The Board of Directors may
provide, by resolution, the time and place, either within or without the State
of South Dakota, for the holding of additional regular meetings without other
notice than such resolution.

     SECTION 3.4 SPECIAL MEETINGS: Special meetings of the Board of Directors
may be called by or at the request of the Chairman of the Board, the President
or any two directors. The person or persons authorized to call special meetings
of the Board of Directors may fix any


                                       4



place, either within or without the State of South Dakota, as the place for
holding any special meeting of the Board of Directors called by them.

     SECTION 3.5 NOTICE: Notice of any special meeting shall be given at least
forty-eight (48) hours prior to the meeting by notice communicated in person, by
telephone, telegraph, facsimile transmission or other form of wire or wireless
communication, or by mail or private courier. If mailed, such notice shall be
deemed effective when deposited in the United States mail addressed to the
director at the director's business address, with postage thereon prepaid.
Whenever any notice is required to be given to any director of the corporation
under the Articles of Incorporation, these Bylaws, or any provision of law, a
waiver thereof in writing signed at any time, whether before or after the time
of the meeting by the director entitled to notice, shall be deemed the
equivalent of the giving of such notice. The attendance of a director at a
meeting shall constitute a waiver of notice of such meeting, except where a
director attends a meeting for the express purpose of objecting to the
transaction of any business because the meeting is not lawfully called or
convened. Unless otherwise required by the Articles of Incorporation, these
Bylaws, or any provision of law, neither the business to be transacted at, nor
the purpose of, any regular meeting of the Board of Directors need be specified
in the notice or waiver of notice of such meeting.

     SECTION 3.6 QUORUM: A majority of the number of directors elected and who
have qualified for their position shall constitute a quorum for the transaction
of business at any meeting of the Board of Directors, but if less than a
majority is present at a meeting, a majority of the directors present may
adjourn the meeting from time to time without further notice.

     SECTION 3.7 MANNER OF ACTING: The act of the majority of the directors
present at a meeting at which a quorum is present shall be the act of the Board
of Directors, unless the act of a greater number is required by law, or by the
Articles of Incorporation or these Bylaws.

     SECTION 3.8 ACTION WITHOUT A MEETING: Any action required or permitted by
the Articles of Incorporation, these Bylaws or any provision of law to be taken
by the Board of Directors at a meeting may be taken without a meeting if a
consent in writing, setting forth the action so taken, shall be signed by all of
the directors then in office.

     SECTION 3.9 REMOVAL: A director may be removed from office by affirmative
vote taken at a special meeting of the shareholders called for that purpose. If
less than the entire Board is to be removed, no one of the directors may be
removed if the votes cast against his or her removal would be sufficient to
elect him or her if then cumulatively voted at an election of the entire Board
of Directors.

     SECTION 3.10 VACANCIES: Any vacancy occurring in the Board of Directors may
be filled by the affirmative vote of a majority of the remaining directors
though less than a quorum of the Board of Directors. A director elected to fill
a vacancy shall be elected for the unexpired term of his or her predecessor in
office. Any directorship to be filled by reason of an increase in the number of
directors shall be filled by the Board of Directors for a term of office
continuing only until the next election of directors by the shareholders.

     SECTION 3.11 COMPENSATION: The Board of Directors by affirmative vote of a
majority of the directors then in office, and irrespective of any personal
interest of any of its members, may provide for the payment of the expenses of
the directors, if any, of attendance at each meeting at the Board of Directors,
and may establish reasonable compensation of all directors for services to the
corporation as directors, officers or otherwise. The Board of Directors also
shall have authority to provide for reasonable pensions, disability or death
benefits, and other benefits or payments, to directors, officers and employees
and to their estates, families, dependents or beneficiaries on account of prior
service rendered by such directors, officers and employees to the corporation.
No such payment shall preclude any director from serving the corporation in any
other capacity and receiving compensation therefor.

     SECTION 3.12 PRESUMPTION OF ASSENT: A director of the corporation who is
present at a meeting of the Board of Directors at which action on any corporate
matter is taken shall be presumed to have assented to the action taken unless
his or her dissent shall be entered in the minutes of the meeting or unless he
or she shall file his or her written dissent to such action with the person
acting as the secretary of the meeting before the adjournment therefor or shall
forward such dissent by registered mail to the Secretary of the corporation
immediately after adjournment of the meeting. Such right to dissent shall not
apply to a director who voted in favor of such action.

     SECTION 3.13 COMMITTEES: The Board of Directors by resolution adopted by
the affirmative vote of a majority of the number of directors fixed pursuant to
Section 3.2 hereof may designate an Executive Committee and one or more other
committees, each committee to consist of two (2) or more directors elected by
the Board of Directors. The Executive Committee shall have and may exercise,
when the Board of Directors is not in session, the powers of the Board of
Directors in the management of the business and affairs of the corporation,
except action in respect to dividends to shareholders, election of officers,
amending the Articles of Incorporation, amending these Bylaws, adopting a plan
of merger or consolidation, recommending to the shareholders the sale, lease,
exchange or other disposition of all or substantially all of the property and
assets of the corporation otherwise than in the usual or regular course of its
business, recommending to the shareholders a voluntary dissolution of the
corporation or a revocation thereof, or the filling of vacancies in the Board of
Directors or committees created pursuant to this Section 3.13. The other
committees, if any, shall have and may exercise such powers as may be provided
in the resolution of the Board of Directors designating such committee, as such
resolution may from time to time be amended and supplemented. The Board of
Directors may elect one or more of its members as alternate members of any such
committee who may take the place of any absent member or members at any meeting
of such committee, upon request by the Chairman of the Board, the President or
upon request by the chairman of such meeting. Each such committee shall fix its
own rules governing the conduct of its activities and shall make such reports to
the Board of Directors of its activities as the Board of Directors may request.

of Directors may be removed by the Board of Directors whenever in its judgment
the best interests of the corporation would be served thereby, but such removal

removed. Election or appointment of an officer or agent shall not of itself
create contract rights.

resignation, removal, disqualification or otherwise may be filled by the Board
of Directors for the unexpired portion of the term.

     SECTION 4.5 CHAIRMAN OF THE BOARD: The Chairman of the Board shall be the

Directors. The Chairman may sign, with the Secretary or any other proper officer
of the corporation thereunto authorized by the Board of Directors, certificates
for shares of the corporation, any deeds, mortgages, bonds, contracts, or other
instruments which the Board of Directors has authorized to be executed, except

of day-to-day supervision of the business of the corporation. In the absence of
the Chairman of the Board, the President shall, when present, preside at all
meetings of the shareholders and of the Board of Directors. The President shall
have the authority, subject to such rules as may be prescribed by the Board of
Directors, to appoint such agents and employees of the corporation as he or she


                                       7

delegate authority to them. The President shall have authority to sign, execute
and acknowledge, on behalf of the corporation, all deeds, mortgages, bonds,
stock certificates, contracts, leases, reports and all other documents or
instruments necessary or proper to be executed in the course of the
corporation's regular business, or which shall be authorized by resolution of

and securities of the corporation; (b) receive and give receipts for moneys due

such as salary, commission, bonus, interest, or rent, which shall be disallowed
in whole or in part as a deductible expense by the Internal Revenue Service,

subject to the determination of the directors, proportionate amounts may be
withheld from his or her future compensation payments until the amount owed to

                                 INDEMNIFICATION

     SECTION 5.1 THIRD PARTY ACTIONS: The corporation may indemnify any person
who is made, or threatened to be made, a party to any action, suit or
proceeding, whether civil, criminal, administrative or investigative, including
all appeals (including but not limited to an action, suit or proceeding by or in
the right of the corporation) by reason of the fact that he or she (hereinafter
an "Indemnitee") is or was a director, officer, employee or agent of the
corporation, or a fiduciary within the meaning of the Employee Retirement Income
Security Act of 1974 with respect to any employee benefit plan of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent, or as a fiduciary of an employee benefit
plan, of another corporation, limited liability company, partnership, joint
venture, trust or other enterprise, against expenses, including attorneys' fees,
judgments, decrees, fines, penalties, and amounts paid in settlement actually
and reasonably incurred by the Indemnitee in connection with such action, suit
or proceeding, if the Indemnitee acted in good faith and in a manner which the
Indemnitee reasonably believed to be in, or not opposed to, the best interests
of the corporation and, with respect to any criminal action or proceeding, had
no reasonable cause to believe his or her conduct was unlawful. The termination
of any action, suit or proceeding by judgment, order, settlement, or conviction,
or upon a plea of nolo contendere or its equivalent shall not, of itself, create
either a presumption that the Indemnitee did not act in good faith and in a
manner which the Indemnitee believed to be in or not opposed to the best
interests of the corporation or, with respect to any criminal action or
proceeding, a presumption that the Indemnitee had reasonable cause to believe
that his or her conduct was unlawful.

     SECTION 5.2 DERIVATIVE ACTIONS: The corporation may indemnify any person
who is a party to any threatened, pending, or completed action or suit,
including all appeals, by or in the


                                       9



right of the corporation to procure a judgment in its favor by reason of the
fact that the Indemnitee is or was a director, officer, employee or agent of the
corporation or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, limited liability
company, partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees) actually and reasonably incurred by the Indemnitee
in connection with the defense or settlement of such action or suit if the
Indemnitee acted in good faith and in a manner the Indemnitee reasonably
believed to be in or not opposed to the best interests of the corporation;
provided, however, that no indemnification shall be made in respect of any
claim, issue or matter as to which the Indemnitee shall have been finally
adjudged to be liable for negligence or misconduct in the performance of his or
her duty to the corporation unless, and only to the extent that the court in
which such action or suit was brought shall determine upon application that, in
view of all of the circumstances of the case, and despite the adjudication of
liability, the Indemnitee is fairly and reasonably entitled to indemnity for
such expenses as such court shall deem proper.

     SECTION 5.3 RIGHTS AFTER SUCCESSFUL DEFENSE: To the extent that a director,
officer, employee or agent of the corporation has been successful on the merits
or otherwise in defense of any action, suit or proceeding referred to in
Sections 5.1 or 5.2, or in defense of any claim, issue or matter therein, the
Indemnitee shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by the Indemnitee in connection therewith.

     SECTION 5.4 OTHER DETERMINATION OF RIGHTS: Except in a situation governed
by Section 5.3, any indemnification under Sections 5.1 or 5.2 (unless ordered by
a court) shall be made by the corporation only as authorized in a specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in the circumstances because the Indemnitee has met the
applicable standard of conduct set forth in Sections 5.1 and 5.2. Such
determination shall be made (a) by a majority vote of directors acting at a
meeting at which a quorum consisting of directors who are not parties to such
action, suit or proceeding is present; (b) if such a quorum is not obtainable,
or, even if obtainable a quorum of disinterested directors so directs, by
independent legal counsel in a written opinion; or (c) by the shareholders by a
majority vote of a quorum consisting of shareholders who are not parties to such
action, suit or proceeding.

     SECTION 5.5 ADVANCES OF EXPENSES: Expenses of each person indemnified
hereunder (including attorneys' fees) incurred in defending a civil, criminal,
administrative, or investigative action, suit, or proceeding (including all
appeals) may be paid by the corporation in advance of the final disposition of
such action, suit or proceeding upon a preliminary determination following one
of the procedures set forth in Section 5.4 that the director, officer, employee
or agent meets the applicable standard of conduct set forth in Section 5.1 or
5.2 and upon receipt of an undertaking by or on behalf of the director, officer,
employee, or agent to repay such amount unless it shall ultimately be determined
that he or she is entitled to be indemnified by the corporation.

     SECTION 5.6 NONEXCLUSIVENESS: The indemnification provided by this Section
5 shall not be deemed exclusive of any other rights to which those seeking
indemnification may be entitled as a matter of law or under the Articles of
Incorporation, these Bylaws, any agreement, vote of shareholders, any insurance
purchased by the corporation, or otherwise, both as to action


                                       10



in the Indemnitee's official capacity and as to action in another capacity while
holding such office, and shall continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person; provided, however, the
corporation may not provide for indemnification against gross negligence or
willful misconduct, under any by-law, agreement, vote of shareholders or
disinterested directors, or otherwise, both as to action in the Indemnitee's
official capacity and as to action in another capacity while holding such
office.

     SECTION 5.7 PURCHASE OF INSURANCE: The corporation may purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
limited liability company, partnership, joint venture, trust, or other
enterprise against any liability asserted against him or her and incurred by him
or her in such capacity, or arising out of his or her status as such, whether or
not the corporation would have the power to indemnify him or her against such
liability under the provisions of this Section 5 or of South Dakota's general
corporation law.
