                                ESCROW AGREEMENT

     THIS ESCROW AGREEMENT (this "Agreement") is made this 14th day of November
2002, by and between East Kansas Agri-Energy, L.L.C. a Kansas limited liability
company ("EKAE") and Garnett State Savings Bank as escrow agent (the "Escrow
Agent").

                              W I T N E S S E T H:

     WHEREAS, EKAE proposes to offer a minimum 9,000 and a maximum of 18,000 of
its Membership Units (the "Units") at a price of $1,000 per Unit, in minimum
blocks of ten (10) Units in an offering in the States of Kansas and Missouri,
and possibly other states, made pursuant to an registration under the provisions
of the Securities Act of 1933, as amended (the "Offering");

     WHEREAS, EKAE will file a registration statement to register the Units with
the Securities and Exchange Commission, the States of Kansas and Missouri, and
possibly other states;

     WHEREAS, EKAE will allow investors in the Offering to delivery the purchase
price of the subscribed Units in installments; and

     WHEREAS, EKAE desires to comply with the requirements of the Securities Act
of 1933 and of the various state regulatory statutes and regulations, and
desires to protect the investors in the Offering by providing, under the terms
and conditions herein set forth, for the return to subscribers of the money
which they may pay on account of purchases of Units in the Offering if the
Minimum Escrow Deposit (hereinafter defined) is not deposited with the Escrow
Agent.

     NOW, THEREFORE, in consideration of the mutual covenants herein contained
and for other good and valuable consideration, the receipt and sufficiency of
which is acknowledged, the parties agree as follows:

     1.   ACCEPTANCE OF APPOINTMENT. Garnett State Savings Bank hereby agrees to
act as escrow agent under this Agreement. The Escrow Agent shall have no duty to
enforce any provision hereof requiring performance by any other party hereunder.

     2.   ESTABLISHMENT OF ESCROW ACCOUNT. An escrow account (the "Escrow
Account") is hereby established with the Escrow Agent for the benefit of the
investors in the Offering. Except as specifically provided in this Agreement,
the Escrow Account shall be created and maintained subject to the customary
rules and regulations of the Escrow Agent pertaining to such accounts.

     3.   OWNERSHIP OF ESCROW ACCOUNT. Until such time as the funds deposited in
the Escrow Account (the "Deposited Funds") shall equal the Minimum Escrow
Deposit (as hereinafter defined), all funds deposited in the Escrow Account by
EKAE shall not become the property of EKAE or be subject to the debts of EKAE or
any other person but shall be held by the Escrow Agent solely for the benefit of
the investors who have purchased Units in the Offering.

                                        1
<Page>

     4.   DEPOSIT OF PROCEEDS. All proceeds from sales of Units in the Offering
shall be delivered by EKAE to the Escrow Agent, within forty-eight hours of the
receipt thereof from investors, endorsed (if appropriate) to the order of the
Escrow Agent, together with an appropriate written statement setting forth name,
address and social security number of each person purchasing Units, the number
of Units purchased, and the amount paid by each such purchaser. Any such
proceeds deposited with the Escrow Agent in the form of uncollected checks shall
be promptly presented by the Escrow Agent for collection through customary
banking and clearing house facilities. As the proceeds of each sale are
deposited with the Escrow Agent, EKAE shall reserve the number of Units
confirmed to the purchaser thereof in connection with such sale. All such
deposited proceeds are referred to herein as the "Escrow Funds".

     5.   INVESTMENT OF ESCROW ACCOUNT. The Escrow Funds shall be credited by
Escrow Agent and recorded in the Escrow Account. The Escrow Agent shall be
permitted, and is hereby authorized to deposit transfer, hold and invest all
funds received under this Agreement, including principal and interest, in a
Repurchase Agreement at Garnett State Savings Bank, to yield a variable interest
rate equal to the Federal Reserve Discount rate for the Kansas City Region minus
1/4%, variable daily as the Federal Reserve Discount rate changes. Escrow Agent
shall pledge bank investments guaranteed by the U.S. Government or its agencies
to secure the Repurchase Agreement. Any interest received by Escrow Agent with
respect to the Escrow Funds shall be paid to EKAE on the termination of the
escrow.

     6.   TERMINATION OF ESCROW. This Agreement and the Escrow created hereunder
shall be terminated as provided in paragraph 7 hereof or as of the date in
calendar year 2003 (the "Termination Date") one year following the date in
calendar year 2002 upon which the Securities and Exchange Commission authorizes
the Offering (the "Offering's Effective Date"). EKAE shall notify Escrow Agent
of the Offering's Effective Date within thirty (30) days of its receipt from the
Securities and Exchange Commission. In no event shall the Termination Date be
later than June 30, 2004.

     7.   DISPOSITION OF ESCROW FUNDS. The Escrow Agent shall have the following
duties and obligations under this Agreement:

     A.   The Escrow Agent shall send a written notice acknowledging the receipt
of the Deposited Funds every seven days to EKAE. The Escrow Agent shall give
EKAE prompt written notice when the Deposited Funds total $500,000, $900,000,
$1.4 million, and $1.6 million.

     B.   The Escrow Agent shall give EKAE prompt written notice when the
Deposited Funds equal $900,000. Following receipt of such notice, EKAE will
advise the purchasers of Units to remit to the Escrow Agent the balance of the
purchase price within twenty (20) days. Thereafter, Escrow Agent shall give EKAE
prompt written notice when the Deposited Funds total $5.0 million, $9.0 million,
$14.0 million, and $16.0 million.

     C.   At the time (and in the event) that: (a) the Deposited Funds shall,
during the term of this Agreement, equal $9.0 million in subscription proceeds
(exclusive of interest) (the "Minimum Escrow Deposit"), (b) the Escrow Agent
shall have received written confirmation from EKAE that

                                        2
<Page>

EKAE has obtained a written debt financing commitment sufficient to carry out
its business plan, (c) EKAE has affirmatively elected, in writing, to terminate
this Agreement, (d) the Escrow Agent has provided the Office of the Securities
Commissioner of Kansas with written notification of the occurrence of items (a),
(b), and (c) of this paragraph 7C, and (e) the Commissioner has provided the
Escrow Agent and the EKAE with written consent to release the Deposited Funds,
then this Agreement shall terminate, and the Escrow Agent shall promptly
disburse the funds on deposit, including interest, to EKAE to be used in
accordance with the provisions set out in the Registration Statement (as may be
amended) which will be used in Offering the Units. EKAE will deliver a copy of
the Registration Statement to the Escrow Agent upon execution of this Agreement.
The Escrow Agent will have no responsibility to examine the Registration
Statement with regard to the Escrow Account or otherwise. Upon the making of
such disbursement, the Escrow Agent shall be completely discharged and released
of any and all further responsibilities hereunder.

     D.   In the event the Deposited Funds do not equal or exceed the Minimum
Escrow Deposit on or before the Termination Date, the Escrow Agent shall return
to each of the purchasers of the Units in the Offering, as promptly as possible
after such Termination Date and on the basis of its records pertaining to the
Escrow Account: (a) the sum which each purchaser initially paid in on account of
purchases of the Units in the Offering and (b) subject to paragraph 10 hereof,
each purchaser's portion of the total interest earned on the Escrow Account as
of the Termination Date, (c) reduced by a processing fee paid to Escrow Agent of
Twenty Dollars ($20.00) per purchaser. Computation of any purchaser's share of
the net interest earned will be a weighted average based on the proportion of
such purchaser's deposit in the Escrow Account from the Offering to all such
purchasers' deposits held by the Escrow Agent and upon the length of time in
days such deposit was held in the Escrow Account as compared to all such
deposits. All computations with respect to each purchaser's allocable share of
net interest shall be made by the Escrow Agent, which determinations shall be
final and conclusive. Any amount paid or payable to a purchaser pursuant to this
paragraph shall be deemed to be the property of such purchaser, free and clear
of any and all claims of EKAE or its agents or creditors; and the respective
purchases of the Units made and entered into in the Offering shall thereupon be
deemed, ipso facto, to be cancelled without any further liability of the
purchasers or any of them to pay for the Units purchased. At such time as the
Escrow Agent shall have made all the payments called for in this paragraph, the
Escrow Agent shall be completely discharged and released of any and all further
responsibilities hereunder, and the Units reserved (as provided in paragraph 4)
shall be released from such reservation.

     8.   AGREEMENT WITH ESCROW AGENT. To induce Escrow Agent to act hereunder,
it is agreed by EKAE that:

     A.   The sole duty of the Escrow Agent, other than as herein specified,
shall be to receive the Escrow Funds and hold them subject to release, in
accordance herewith, and the Escrow Agent shall be under no duty to determine
whether EKAE is complying with requirements of this Agreement in tendering to
the Escrow Agent said proceeds of the sale of said Units. The Escrow Agent may
conclusively rely upon and shall be protected in acting upon any statement,
certificate, notice, request, consent, order or other document believed by it to
be genuine and to have been signed or presented by the proper party or parties.
The Escrow Agent shall have no duty or liability

                                        3
<Page>

to verify any such statement, certificate, notice, request, consent, order or
other document, and its sole responsibility shall be to act only as expressly
set forth in this Agreement. The Escrow Agent shall be under no obligation to
institute or defend any action, suit or proceeding in connection with this
Agreement unless first indemnified to its satisfaction. The Escrow Agent may
consult counsel in respect of any question arising under this Agreement and the
Escrow Agent shall not be liable for any action taken or omitted in good faith
upon advice of such counsel.

     B.   EKAE hereby indemnifies and holds harmless the Escrow Agent from and
against any and all loss, liability, cost, damage and expense, including,
without limitation, reasonable counsel fees, which the Escrow Agent may suffer
or incur by reason of any action, claim or proceeding brought against the Escrow
Agent arising out of or relating in any way to this Agreement or any transaction
to which this Agreement relates unless such action, claim or proceeding is the
result of the gross negligence or willful misconduct of the Escrow Agent.

     9.   RESIGNATION AND REMOVAL OF ESCROW AGENT SUCCESSORS. The Escrow Agent
may resign upon thirty (30) days advance written notice to EKAE. If a successor
Escrow Agent is not appointed within the 30-day period following such notice,
Escrow Agent may petition any court of competent jurisdiction to name a
successor Escrow Agent. Any commercial banking institution or trust company with
which Escrow Agent may merge or consolidate, and any commercial banking
institution or trust company to which Escrow Agent transfers all or
substantially all of its corporate trust business shall be the successor Escrow
Agent without further act.

     10.  FEES AND EXPENSES OF ESCROW AGENT. In the event the Deposited Funds do
not equal or exceed the Minimum Escrow Deposit before the Termination Date the
Escrow Agent shall be entitled to a fee of Twenty Dollars ($20.00) per
purchaser, which fees shall be paid from interest on the escrow account only and
not from principal. The fee agreed upon in the event of termination of the
escrow without the required Minimum Escrow Deposit and the continued deposit of
said escrow in the Repurchase Agreement as set forth in paragraph 5 herein is
intended as full consideration for the Escrow Agent's services as contemplated
by this Agreement; PROVIDED, HOWEVER, that in the event the Escrow Agent renders
any material service not contemplated in this Agreement or there is any
assignment of interest in the subject matter of this Agreement, or any material
modification hereof; or if any material controversy arises hereunder, or the
Escrow Agent is made a party to any litigation pertaining to this Agreement, or
the subject matter hereof, then the Escrow Agent shall be reasonably compensated
for such extraordinary services and reimbursed for all costs and expenses,
including reasonable attorney's fees, occasioned by any delay, controversy,
litigation or event, and the same shall be recoverable from EKAE, but not from
the escrow account.

     11.  NOTICES. All notices, requests, demands, and other communications
under this Agreement shall be in writing and shall be deemed to have been duly
given (a) on the date of service if served personally on the party to whom
notice is to be given, (b) on the day of transmission if sent by facsimile
