 stock and that it is not a loan.

         9. The parties intend this agreement to outline transactions planned to
 take place as described in paragraph one and to accommodate the intended
 transactions. If for any reason any transaction does not occur or the funds are
 not sent by Mammoth Corporation or the shares are not freely and electronically
 transferable by Mammoth Corporation, the agreement is null and void, except any
 completed transaction will stand and if (in the unlikely event) only one side
 of any transaction has occurred, both parties agree that neither party shall be
 unjustly enriched and any party receiving consideration without sending the
 agreed consideration will promptly return the one sided consideration.

         10. This Agreement embodies the entire agreement and understanding
between the parties hereto and supersedes all prior agreements and
understandings relating to the subject matter hereof.

consents to the jurisdiction of that Court for resolution of any disputes that
may arise. This Agreement shall be construed and enforced in accordance with and
governed by the laws of the State of Illinois, and to the extent applicable, the
law of the United States. In the event that Buyer resorts to litigation relating
to the rights afforded herein, Seller shall be responsible for the costs
incurred by Buyer associated with any such litigation, including reasonable
attorney fees, provided Buyer is the prevailing party in any such action
regardless of whether the action is brought by Buyer or Seller. The parties
agree that a document signed and sent electronically including via facsimile or
