FORM 10-Q FOR THE QUARTER  ENDED FEBRUARY 29, 2008

Note 1.  Basis of Presentation

Revenue Recognition, page 8

2. We note your response to prior comment 7.  You disclose that shipping costs are
incurred by third-party brokers and factored in to their net sales price rather than being
charged back to you.  However, your respons e indicates that your contract with CHS
Inc. requires you to bear all freight costs incurred by the buyer in delivering the product to its customer.  Please revise your disclosure as necessary to clarify which party is responsible for shipping costs.

Item 4.  Controls and Procedures, page 26

3. In your Form 10-K for the year ended November 30, 2007, you concluded that your
disclosure controls and procedures were  not effective because of the material
weakness in internal controls  over financial reporting identified.  In your Form 10-Q
for the quarter ended February 29, 2008, you disclose that you had not tested your
controls over revenue recognition cutoffs during fiscal 2008 and accordingly had not
determined that the material weakness had been fully remediated.   In light of this,
please disclose how you were able to conc lude that your disclosure controls and
procedures were effective.
