                     EXCLUSIVE GRAIN SUPPLY AGREEMENT

AGREEMENT made this 1st day of January, 1997, by and between 
Mike Rowan, an individual resident of 1620 Magnolia, Liberty, 
Missouri, 64068 "Rowan" and High Plains Corporation, a Kansas corporation 
with its principal offices at 200 W. Douglas, Suite 820, Wichita, 
Kansas 67202, "High Plains".

  WHEREAS, High Plains is a purchaser of grain for use at its 
Colwich, Kansas and York, Nebraska plants, and Rowan has expertise 
in the grain and feed business; and

  WHEREAS, both Rowan and High Plains desire to enter into an 
exclusive supply agreement for the procurement of grain by Rowan 
for High Plains for use at High Plains' Colwich, Kansas and York, 
Nebraska, plants.

  NOW, THEREFORE, in consideration of the mutual agreements and 
other good and valuable consideration hereinafter set forth, the 
parties agree as follows:

   1.  SALE OF PRODUCTS.  This Agreement applies to all grain 
purchased by High Plains for use at its Colwich, Kansas and York, 
Nebraska, plants (the "Grain").  High Plains agrees to buy all of 
its requirements of Grain through Rowan, who will contract for 
High Plains as an independent contractor, during the term of this 
Agreement.  Rowan agrees to sell or acquire for the benefit of 
High Plains, subject to availability, such Grain to High Plains 
for the term of this Agreement.  Rowan and High Plains agree that 
such purchases will be at terms, conditions and price as agreed 
upon. Title and risk of loss for grain shall pass to High Plains 
upon unloading of the grain at High Plains plant. Rowan shall 
provide grain in quantities as necessary to permit High Plains to 
maintain its usual production schedule.

   2.  FORECAST INFORMATION.  Rowan agrees to provide High Plains 
with regular feedgrain analyses and other forecast information 
available from third-parties to assist High Plains in its purchase 
decisions.  However, regardless of any price or purchase 
recommendations or forecasts provided by Rowan, High Plains 
remains solely responsible for its purchasing decisions and any 
gains or losses resulting from those decision.  Rowan PROVIDES NO 
WARRANTY AS TO ANY PRICING PROJECTIONS, FORECASTS OR PURCHASE 
RECOMMENDATIONS.  Rowan further agrees to provide the following 
additional services to High Plains during the term of this 
agreement at his own cost and expense:  a) continually monitor, 
arrange and adjust scheduling of grain shipments to meet High 
Plains needs; b) responsibility for truck and rail transportation 
needs, including price management techniques such as back-hauls 
and arbitrage arrangements; c) sourcing of alliances with third 
parties for storage and execution backstops as needed; d) 
accounting and auditing for transportation, grain taxes, cash flow 
management, etc.; e) assist High Plains in lobbying efforts in


<PAGE>


grain and feed areas; f) assist in implementation and monitoring 
of appropriate risk management procedures relating to High Plains 
grain needs; and g) communicate and cooperate with designated High 
Plains personnel in determining grain needs, sourcing, scheduling 
and pricing grain, and coordinating the other services Rowan 
agrees to perform for High Plains pursuant to this agreement.

   3.  PRICE.  Rowan agrees to supply grain to High Plains at a 
fixed price, F.O.B. Colwich, Kansas or York, Nebraska.  Rowan will 
absorb the costs of all freight, transportation, inventory carry 
charges, and all state or other grain taxes prior to delivery of 
grain. Rowan will use his best efforts to obtain the lowest 
possible total grain cost for High Plains under prevailing market 
conditions.  High Plains shall pay Rowan the amount actually paid 
by Rowan to his supplier for the grain, plus actual freight 
incurred (crediting reductions for backhaul or arbitrage 
arrangements), plus grain taxes paid , plus a fee in the amount of 
$.0175 per bushel. The parties may also agree to enter into 
certain hedging, or other futures agreements from time to time, in 
which event all costs of such hedging, including margin calls and 
commissions, will be the responsibility of High Plains.  Rowan 
agrees to back up all contracts for delivery of grain to High 
Plains with either futures or trades on the Chicago Board of 
Trade, or with individual supply contracts from farmers, local 
elevators, or other legitimate sources, and shall provide evidence 
of this backup to High Plains upon request.  All such futures or 
contracts shall be executed on behalf of, and transacted in the 
name of High Plains by Rowan, upon approval of High Plains.  Rowan 
shall keep complete and accurate records of all transactions made 
for the benefit of High Plains, and High Plains shall have the 
right to audit and copy all records in any way relating to grain 
or futures contracts purchased, or to expenses incurred in 
connection with said transactions, upon reasonable notice to 
Rowan, and at the sole expense of High Plains.  The parties agree 
that after the first 90 days of the term of this agreement has 
passed, they will cooperate in attempting to establish a mutually 
agreeable method for measuring Rowan's effectiveness as a grain 
purchasing agent, with the idea that if Rowan's performance under 
this contract can be effectively measured, and his efforts have 
resulted in significant savings to High Plains, then Rowan's fee 
arrangement may be restructured to include a performance bonus 
provision agreeable to both parties.

   4.  PAYMENT.  Payment for purchases under this Agreement are 
due daily, and shall be made by drafting an account of High 
Plains' choice on the first business day following delivery to 
High Plains.  The weight of Raw Grains delivered by Rowan to High 
Plains shall be established by weight certificates.  High Plains 
shall obtain truck weights on the scales at the High Plains 
Plants, which shall be maintained by High Plains as required by 
applicable laws, rules and regulations, and rail weights will be 
obtained on any certified railroad scales.  Whenever High Plains


<PAGE>


truck scales are unavailable or inoperable, any certified scales 
may be used, at High Plains expense, until High Plains scales are 
restored.  The inbound weight certificates shall be determinative 
of the quantity of Raw Grains for which High Plains is obligated 
to pay pursuant to Section 3 hereof.

   5.  TERM.  This Agreement shall commence on January 31, 1997 
and continue for one year.  After the first year, the Agreement 
shall automatically renew for one-year terms.  However, either 
party may terminate this Agreement at any time upon giving the 
other party thirty (30) days notice of termination in writing.  
This Agreement may be terminated immediately by either party if 
(i) the other party's financial responsibility becomes impaired, 
(ii) the other party makes an assignment or arrangement for 
benefit of creditors or (iii) files a petition in bankruptcy or 
has such petition filed against it.

  Upon expiration, termination, or cancellation of this Agreement, 
neither party shall have any rights or obligations or liability to 
the other party with respect to this Agreement except for (a) the 
obligation to make full payment of any outstanding monetary 
obligations owed to the other party which monetary obligation was 
incurred prior to the date of such expiration, termination or 
cancellation, and (b) obligations under any Grain or futures 
contract which existed prior to such expiration, termination or 
cancellation of this Agreement.

   6.  EMPLOYEES.  The parties agree that Rowan is not an employee 
of High Plains, and that his relationship is that of an 
Independent contractor only.  Each party shall be solely 
responsible for the acts and inactions of its own employees acting 
within the course and scope of their employment by such party and 
each party shall be solely responsible for the salary, wages and 
payroll taxes for its employees and shall maintain Workers' 
Compensation Insurance on its employees as required by applicable

inactions of, the employees of the other party as a result of this 
Agreement.
