                  meter
                  or weight certificates shall be determinative of the quantity of
                  the
                  bio-diesel for which Eco is obligated to pay pursuant to Section
                  2 above,

                (a)

              	
                Eco,
                  in consultation with SOUTHERN IOWA BIOENERGY, shall be responsible
                  for
                  estimating the number of rail car leases required to handle the

                  that
                  if tank cars for bio-diesel are not loaded to full visible capacity,
                  SOUTHERN IOWA BIOENERGY shall pay in full the portion of freight
                  charges
                  allocable to the unused capacity of the car. Such invoiced amounts
                  shall
                  be paid by Eco to SOUTHERN IOWA BIOENERGY the Friday following
                  receipt of
                  such invoice by Eco.

                  shall negotiate the terms of and execute such rail car leases and
                  rates on
                  behalf of SOUTHERN IOWA BIOENERGY; provided, however, that any

                  rail car leases executed by Eco shall be in substantially the same
                  form as

                  biodiesel
                  production industry. All rail leases shall be placed in the sole

                Notwithstanding
                  the foregoing, SIBE shall have the right, upon 10 days advance
                  notice to
                  Eco, to elect to make arrangements for the transportation of the
                  biodiesel
                  with such transportation provider(s) and for such period(s) during
                  the
                  term of the Agreement as specified in the notice to Eco; provided,
                  however, that the service and rates of the transportation provider(s)
                  selected by SIBE shall be comparable to and competitive with the
                  service
                  and rates of similar transportation providers in the bio-diesel
                  industry.
                  In such event, Eco shall utilize the transportation services arranged
                  by

                  as
                  mutually agreed by the parties, such election shall not otherwise
                  alter
                  the duties of Eco or SIBE under this Agreement. Eco-Energy shall
                  have the
                  ability to utilize additional carriers as needed during the term

                    IOWA BIOENERGY by written notice specifying the breach, which
                    notice shall
                    be effective fifteen
                    (15)
                    days after it is given unless SOUTHERN IOWA BIOENERGY cures the
                    breach
                    within such

                    Eco as to SOUTHERN IOWA BIOENERGY that cannot be resolved within
                    15 days,
                    both parties may mutually agree in writing as to the length of
                    time needed
                    to resolve the material breach.

                

        

        

        
          	 	
                  (c)

                	
                  This
                    Agreement may also be terminated at any time upon the mutual
                    written
                    consent of
                    both
                    parties on such terms as the parties may
                    agree.

                  In
                    addition to any other method of terminating this Agreement, Eco
                    may
                    unilaterally terminate this Agreement at any time if such termination
                    shall be required by any regulatory
                    authority, and such termination shall be effective on the 30th
                    day following the giving of notice of intent to terminate; provided,
                    however, that if such termination is required due to Eco's wrongful
                    or
                    illegal acts, such termination shall constitute an event of material
                    breach of this Agreement.

                

        

         

        
          
            
            

          

          
            
            

            
              

            

          

          
            
            

          

        

         

        
          	 	
                  (e)

                	
                  In
                    addition
                    to any other rights and remedies the parties may have, either
                    party hereto

                    of
                    written notice to the other party, if the other party (i) is
                    unable to pay
                    its debts as they mature or admits in writing its inability to
                    pay its
                    debts as they mature, (ii) makes a general assignment for the
                    benefit of
                    its creditors, (iii) files a voluntary petition for bankruptcy,
                    or (iv)

                    or
                    substantially all of its assets or permits the appointment of
                    any such
                    receiver or trustee who is not discharged within a period of
                    sixty (60)
                    days after such appointment, with regards to bankruptcy. However
                    the
                    parties are still financially responsible to cover all contracts
                    previously agreed to.

                  Indemnity. The
                    Parties agree that they shall absolve, release and refrain from
                    seeking

                    parties
                    expressly agree to indemnify each other in proportion to their
                    respective

                he is
