    NOW,
      THEREFORE, in consideration of the premises the Parties agree as
      follows:

    

    
      
        
        

      

      
        1

        
          

        

      

      
        
        

      

    

    1.    ACCEPTANCE
      OF APPOINTMENT:
      Escrow
      Agent 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 the Company shall not become the property
      of
      the Company or be subject to the debts of the Company or any other person but
      shall be held by the Escrow Agent solely for the benefit of the
      Subscribers.

    

    4.    ESCROW
      FEES:
      The
      Company hereby agrees to pay the Escrow Agent an advance payment for ordinary
      services rendered hereunder in the amount of $1,000.00 (the "Escrow Fee").
      Notwithstanding the foregoing, no fee paid under this Agreement shall exceed
      the
      amount of interest on the Escrow Account and shall be paid from interest only
      and not from principal. 

    

    5.    DEPOSIT
      OF PROCEEDS:
      All
      proceeds from subscriptions for Units in the Offering shall be delivered by
      the
      Company to the Escrow Agent, within forty-eight hours of the receipt thereof
      from Subscribers, endorsed (if appropriate) to the order of the Escrow Agent,
      together with an appropriate written statement setting forth the name, address
      and social security number/taxpayer identification number of each person or
      entity subscribing for Units, the number of Units subscribed for, and the amount
      paid by each such Subscriber. 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, the Company
      shall
      reserve the number of Units confirmed to the Subscriber thereof in connection
      with such subscription. All such deposited proceeds are referred to herein
      as
      the "Escrow Funds."

    

    6.    INVESTMENT
      OF ESCROW FUNDS:
      The
      Escrow Funds shall be credited by Escrow Agent and recorded in the Escrow
      Account. In accordance with Rule 15c2-4 of the Securities Regulations, 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 savings accounts, bank money market accounts, short term
      certificates of deposit or short term securities issued or guaranteed by the
      U.S. Government. Any
      interest received by Escrow Agent with respect to the Escrow Funds shall be
      paid
      pursuant to the terms of this Agreement.

    

    7.    TERMINATION
      OF ESCROW: This
      Agreement and the Escrow created hereunder shall be terminated as provided
      in
      paragraph 8 hereof or as of the date one year and one day following the date
      upon which the Commission authorizes the Offering (the "Offering's Effective
      Date") or longer if the Commission, upon the request of the Company, extends
      the
      effectiveness of the Offering beyond the initial one year and one day period
      of
      effectiveness (the “Termination Date”), provided; however, if the Company has
      filed for an extension of the offering with the Commission prior to the
      termination date and the application has not been rejected, this Agreement
      shall
      not terminate until such time as the Commission rejects the application for
      extension or for 180 days after the Commission grants such application. Prior
      to
      the Termination Date, the Company has received subscription agreements for
      membership units equal to the minimum offering amount and the Company has
      advised the Subscribers of those membership units to remit to the Escrow Agent
      the balance of the purchase price, then the Escrow may continue beyond the
      Termination Date until all Funds have been paid and the conditions for releasing
      the Funds have been satisfied. In no event shall this date be later than three
      (3) months following the Termination Date. The Company shall notify Escrow
      Agent
      of the Offering's Effective Date or extension thereof, within thirty (30) days

    8.    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 the Company. 

    

    B.    The
      Escrow Agent shall give the Company prompt written notice when the Deposited
      Funds equal $900,000 (exclusive of interest), provided that the Company has
      subscriptions for not less than $20,000,000 and has provided Escrow Agent
      written confirmation of said subscriptions. Following receipt of such notice,
      the Company will advise the Subscribers to remit to the Escrow Agent the balance
      of the purchase price within thirty (30) days. Thereafter, Escrow Agent shall
      give the Company written notice acknowledging the receipt of the Deposited
      Funds
      every seven days. The Escrow Agent shall give the Company prompt written notice
      when the Deposited Funds total $9,000,000 (exclusive of interest). 

    

    C.    At
      the
      time (and in the event) that: (a) the Deposited Funds shall, during the term
      of
      this Agreement, equal $9,000,000 in subscription proceeds (exclusive of
      interest) (the "Minimum Escrow Deposit"); (b) the Company has given written
      notice to Escrow Agent that it has
      entered
      into a definitive agreement with SAFER Energy, LLC (“Safer”) to perform design,
      engineering and construction services for certain parts of the proposed
      biodiesel plant as described in the Safer term sheet; (c)
      the
      Escrow Agent
      shall
      have received written confirmation from the Company that the Company has
      obtained a written debt financing commitment for debt financing of at least
      $25,850,335; (d) the Company has affirmatively elected in writing to terminate
      this Agreement; and (e) the
      Escrow
      Agent shall have provided the Company an affidavit that the Company may file
      in
      the states in which the Units have been registered stating that the foregoing
      requirements (a), (b), (c) and (d) of this subsection 8C have been satisfied,
      then this Agreement shall terminate, and the Escrow Agent shall promptly
      disburse the funds on deposit, including interest, to the Company to be used
      in
      accordance with the provisions set out in the Registration Statement. The
      Company 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, nor shall Escrow Agent have any duty to ensure that Company complies
      with the Registration Statement. 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 or if the Company has not received a written
      debt
      financing commitment or a definitive agreement with Safer as described herein
      on
      or before the Termination Date, the Escrow Agent shall return to each of the
      Subscribers, 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
      Subscriber initially paid in on account of subscriptions for the Units in the
      Offering and (b) each Subscriber’s portion of the total interest earned on the
      Escrow Account as of the Termination Date, (c) reduced by the transaction fees
      provided in paragraph 10 hereof. Computation of any Subscriber’s share of the
      net interest earned will be a weighted average based on the proportion of such
      Subscriber’s deposit in the Escrow Account from the Offering to all such
      Subscribers’ 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 Subscriber’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 Subscriber pursuant to
      this paragraph shall be deemed to be the property of such Subscriber, free
      and
      clear of any and all claims of the Company or its agents or creditors; and
      the
      respective subscriptions for the Units made and entered into in the Offering
      shall thereupon be deemed, ipso facto, to be cancelled without any further
      liability of the Subscribers or any of them to pay for the Units. 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 5) shall be released from such reservation, except that Escrow
      Agent shall be required to prepare and issue a single IRS Form 1099 to each
      Subscriber in the event that funds are returned to Subscribers.

    

    E.    In
      the
      event the Company offers its Subscribers the right to withdraw and terminate
      their subscription agreements pursuant to a rescission offer (“Rescission
      Offer”), upon
      written notice from the Company identifying the Subscribers who have accepted
      the Rescission Offer, the
      Escrow
      Agent shall return to each rescinding Subscriber, as promptly as
      possible on
      the
      basis of its records pertaining to the Escrow Account: (a) the sum which each
      rescinding Subscriber initially paid in on account of subscriptions for the
      Units in the Offering and (b) each rescinding Subscriber's portion of the total
      interest earned on the Escrow Account as of the Rescission Offer termination
      date, (c) reduced by the transaction fees provided in paragraph 10 hereof.
      Computation of any rescinding Subscriber’s share of the net interest earned will
      be a weighted average based on the proportion of such rescinding Subscriber’s
      deposit in the Escrow Account from the Offering to all such rescinding
      Subscribers' 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 rescinding Subscriber’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
      rescinding Subscriber pursuant to this paragraph shall be deemed to be the
      property of such rescinding Subscriber, free and clear of any and all claims
      of
      the Company 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 rescinding
      Subscribers or any of them to pay for the Units. At such time as the Escrow
      Agent shall have made all the payments called for in this paragraph, the Escrow
      Agent shall continue to be bound by the other provisions of this Agreement,
      and
      the Units reserved for each rescinding Subscriber (as provided in paragraph
      5)
      shall be released from such reservation, except that the Escrow Agent shall
      be
      required to prepare and issue a single IRS Form 1099 to each rescinding
      Subscriber.

    9.    LIABILITY
      OF ESCROW AGENT:
      In
      performing any duties under the Escrow Agreement, the Escrow Agent shall not
      be
      liable to the Company, any Subscriber
      or any
      Party for damages, losses, or expenses, except for gross negligence or willful
      misconduct on the part of the Escrow Agent. The Escrow Agent shall not incur
      any
      such liability for (a) any act or failure to act made or omitted in good faith,
      or (b) any action taken or omitted in reliance upon any instrument, including
      any written statement or affidavit provided for in this Agreement that the
      Escrow Agent shall in good faith believe to be genuine, nor will the Escrow
      Agent be liable or responsible for forgeries, fraud, impersonations, or
      determining the scope of any representative’s authority. In addition, the Escrow
      Agent may consult with legal counsel in connection with the Escrow Agent's
      duties under this Agreement and shall be fully protected in any action taken,
      suffered, or permitted by it in good faith in accordance with the advice of
      counsel. The Escrow Agent is not responsible for determining and verifying
      the
      authority of any person acting or purporting to act on behalf of any party
      to
      this Agreement.

    

    10.    FEES
      AND EXPENSES:
      In the
      event the Deposited Funds do not equal or exceed the Minimum Escrow Deposit
      before the Termination Date or the Company does not receive a written debt
      financing commitment as described herein before the Termination Date, or the
      Company offers its Subscribers the right to withdraw and terminate their
      subscription agreements pursuant to a Rescission Offer, the Escrow Agent shall
      be entitled to a fee of $10.00 per Subscriber
      receiving an IRS Form 1099,
      which
      fees shall be paid from the interest on the Escrow Account only and not from
      principal. In the event the Escrow Agent renders any service not provided for
      in
      this Agreement, or if the Company requests a substantial modification of its
      terms, or if any controversy arises, or if the Escrow Agent is made a party
      to,
      or intervenes in, any litigation pertaining to this escrow or its subject
      matter, the Escrow Agent shall be reasonably compensated for such extraordinary
      services and reimbursed for all costs, attorney's fees, including allocated
      costs of in-house counsel, and expenses occasioned by such default, delay,
      controversy or litigation and the Escrow Agent shall have the right to retain
      all documents and/or other things of value at any time held by the Escrow Agent
      in this escrow until such compensation, fees, costs and expenses are paid.
      The
      Company promises to pay these sums upon demand. Unless otherwise provided,
      the
      Company will pay all of the Escrow Agent's usual charges and the Escrow Agent
      may deduct such sums from the interest on the Escrow Account only and not from
      principal deposited to the Escrow Account.

    11.    CONTROVERSIES:
      If any
      controversy arises between the Parties to this Agreement, or with any other
      Party, concerning the subject matter of this Agreement, its terms or conditions,
      the Escrow Agent will not be required to determine the controversy or to take
      any action regarding it. The Escrow Agent may hold all documents and funds
      and
      may wait for settlement of any such controversy by final appropriate legal
      proceedings or other means as, in the Escrow Agent's discretion, the Escrow
      Agent may require, despite what may be set forth elsewhere in this Agreement.
      In
      such event, the Escrow Agent will not be liable for interest or damage.
      Furthermore, the Escrow Agent may at its option file an action of interpleader
      requiring the Parties to answer and litigate any claims and rights among
      themselves. The Escrow Agent is authorized to deposit with the clerk of the
      court all documents and funds held in escrow, except all costs, expenses,
      charges and reasonable attorney fees incurred by the Escrow Agent due to the
      interpleader action and which the Company agrees to pay. Upon initiating such
      action, the Escrow Agent shall be fully released and discharged of and from
      all
      obligations and liability imposed by the terms of this Agreement.

    

    12.    INDEMNIFICATION
      OF ESCROW AGENT:
      The
      Company and its successors and assigns agree jointly and severally to indemnify
      and hold the Escrow Agent harmless against any and all losses, claims, damages,
      liabilities, and expenses, including reasonable costs of investigation, counsel
      fees, including allocated costs of in-house counsel and disbursements that
      may
      be imposed on the Escrow Agent or incurred by the Escrow Agent in connection
      with the performance of its duties under this Agreement, including but not
      limited to any litigation arising from this Agreement or involving its subject
      matter. The Escrow Agent shall have a first lien on the property and papers
      held
      under this Agreement for such compensation and expenses.

    

    13.    RESIGNATION
      OF ESCROW AGENT:
      The
      Escrow Agent may resign at any time upon giving at least (30) days written
      notice to the Company provided, however, that no such resignation shall become
      effective until the appointment of a successor escrow agent which shall be
      accomplished as follows: The Company shall use its best efforts to obtain a
      successor escrow agent within thirty (30) days after receiving such notice.
      If
      the Company fails to agree upon a successor escrow agent within such time,
      the
      Escrow Agent shall have the right to appoint a successor escrow agent authorized
      to do business in the state of Iowa. The successor escrow agent shall execute
      and deliver an instrument accepting such appointment and it shall without
      further acts, be vested with all the estates, properties, rights, powers, and
      duties of the predecessor escrow agent as if originally named as escrow agent.
      The Escrow Agent shall thereupon be discharged from any further duties and
      liability under this Agreement.

    

    14.    AUTOMATIC
      SUCCESSION:
      Any
      company into which the Escrow Agent may be merged or with which it may be
      consolidated, or any company to whom the Escrow Agent may transfer a substantial
      amount of its global escrow business, shall be the Successor to the Agent
      without the execution or filing of any paper or any further act on the part
      of
      any of the Parties, anything herein to the contrary
      notwithstanding.

    8Memorandum
        of Understanding

      Southern
        Iowa BioEnergy, LLC and SAFER Energy, LLC

       

    

    Southern
      Iowa BioEnergy, LLC ("SIBE") and SAFER Energy, LLC ("SAFER") set forth in this
      Memorandum
      of Understanding (the “MOU”) and in the “Proposal For: Southern Iowa Bio-Energy,
      LLC attached hereto as EXHIBIT
      A,
      and by
      this reference incorporated herein (the “Proposal”), dated as of this 6th day of
      November,
      2007,
      an outline of the material terms of the purchase by SIBE of a 40 million gallon
      biodiesel production plant from SAFER, subject to good
      faith negotiations towards definitive documentation (the "Definitive Agreement")
      and as otherwise stated in this MOU. All dollar amounts are in US
      currency.

    

    1) Product
      and Services: SAFER
      will design, manufacture and install a Biodiesel processing plant
      with a rated capacity of 40 million gallons per year (the "Plant") for the
      gross
      purchase price
      of
      $27.5 million payable as follows: $16.5 million in cash and $11 million of
      Equity ("Shares"),
      payable as set forth herein. The Plant shall be capable of producing biodiesel
      to ASTM 6751 and EN 14214 standards and shall be installed at the Osceola site
      in Clarke County, Iowa.

    

    2) Design
      Phase. Upon
      the
      payment to SAFER by SIBE of $1.65 million in cash, and the issuance of
$1.1
      million of Shares to SAFER to be held in escrow and disbursed as provided in
      Section 11 of this MOU (the "Design Deposit"), SAFER shall begin the design
      and
engineering
      of the Plant (the "Design Services") and shall coordinate with the contractor
      chosen
      by
      SIBE for site design and facilities design. If; during the Design Phase, SIBE
      determines
      it is unable to go forward, it shall notify SAFER in writing, which may be
      by
facsimile
      or other electronic means, to stop work. If so notified, SAFER shall stop work
      and refund
      to
      SIBE any portion of the Design Deposit not used by SAFER for costs incurred
      by
SAFER
      for
      such Design Services.

    

    3) Manufacturing
      Phase. Upon
      the
      payment to SAFER by SIBE of $3.3 million in cash, and the issuance
      of $2.2 million of Shares to SAFER, with such Shares to be held in escrow and
      disbursed as provided in Section 11 of this MOU (the "Manufacturing Deposit"),
      SAFER shall begin
      the
      manufacturing of the Plant and the equipment to be installed in the Plant (the

      weeks
      after the payment of the Manufacturing Deposit, SIBE shall make further payments
      to SAFER
      totaling $4.95 million and $3.3 million of Shares in six equal installments
      of
      $825 thousand
      in cash and $550 thousand of Shares each payable every four (4) weeks
      (collectively, with the Manufacturing Deposit, the "Manufacturing Payment"),
      with such Shares to be held in escrow and disbursed as provided in Section
      11 of
      this MOU. Alternatively, If SIBE chooses the
      Letter of Credit method of payment to sub contractors then SIBE shall make
      one
      payment of
      $8.25
      million in cash and issue $5.5 million of Shares to SAFER (with such
Shares
      to
      be held in escrow and disbursed as provided in Section 11 of this
      MOU)
      at the
      time of the Manufacturing Deposit.

      verification by SAFER to SIBE that the Equipment has been shipped, SIBE
shall
      pay
      to SAFER $1.65 million in cash and issue $1.1 million of Shares to SAFER,
with
      such
Shares
      to

      MOU.
      Upon
      delivery of the
      Equipment to the Building Site, SIBE shall pay to SAFER $1.65 million in cash
      and issue $1.1 million of Shares to SAFER, with such Shares
      to
      be held in escrow and disbursed as provided in Section 11 of this
      MOU.

      Agreement, and that any such financing may include provisions and requirements
      to
      be
      included in any Definitive Agreement. Under no circumstances is SIBE obligated
      to perform under this MOU, other than working towards negotiating the Definitive
      Agreement,
      unless and until such financing is secured and, further, SIBE’s payment of the
Initial
      Deposit shall not obligate SIBE to make any further payments to
      SAFER.

    

    9) Title.
      SIBE
      shall not have title to any engineering designs, drawings, and other work
completed
      by SAFER encompassed in the Design Phase until such time as all payments have
      been
      made
      to SAFER by SIBE. Title to the Plant shall transfer to SIBE upon the completion
      of
      the
      Completion Phase.

      shall pay SAFER the sum of $100,000.00 in cash on execution of this MOU.
$50,000
      of this amount will be fully refundable to SIBE should for any reason the two
      parties not
      be
      able to execute the Definitive Agreement. The remaining $50,000 will be fully
      refundable to SIBE in the event SAFER fails to proceed in good faith toward
      the
      execution of the Definitive Agreement.

    

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    11) Escrow

      Shares to be issued by SIBE to SAFER pursuant to this MOU shall be issued in
      SAFER’s name at the time and upon the conditions set forth herein, but shall be
