i.

      which agrees not to assert such defenses against Sentient LP or any
      affiliate. The consideration for this waiver and release is acknowledged
      to include, but not be limited to, the fact that Soda, which is partially
      owned by Holdings, will receive cash as a result of the transactions
      contemplated by this Agreement.




iii.

      to any limitations on the transfer contained in the Securityholder
      Agreement dated March 19, 2004, by and among AmerAlia, Soda, Holdings and
      Sentient LP’s predecessors in interest, Holdings consents to the transfer
      of the Soda Series A Debenture and the Soda Series A Interest to Sentient
      LP.

The
parties agree that any and all ­disputes, claims or controversies arising

privileged and inadmissible for any purpose, including impeachment, in any
arbitration or other proceeding involving the parties, provided that evidence
that is otherwise admissible or discoverable shall not be rendered inadmissible
or non-discoverable as a result of its use in the mediation. Either party may
initiate arbitration with respect to the matters submitted to mediation by
filing a written demand for arbitration at any time following the initial
mediation session or 45 days after the date of filing the written request for
mediation, whichever occurs first. The mediation may continue after the
commencement of arbitration if the parties so desire. ­Unless otherwise
agreed by the parties, the mediator shall be disqualified from serving as
arbitrator in the case. The provisions of this Clause may be enforced by any
Court of competent jurisdiction, and the party seeking enforcement shall be
entitled to an award of all costs, fees and expenses, including attorneys’ fees,
to be paid by the party against whom enforcement is ordered.
