     1.2 CONTINUING GUARANTY. The Guarantor agrees that the obligations pursuant
to this Section 1 are unconditional, absolute, and irrevocable and shall not be
released, discharged or affected in any way by any circumstances or condition,
including without limitation:

          (a) any amendment or modification or other change to any of the

     Transaction Documents or this Guaranty; and

          (d) any other occurrence, circumstance, happening or event, whether
     similar or dissimilar to the foregoing and whether foreseen or unforeseen,
     which otherwise might constitute a legal or equitable defense or discharge
     of the liabilities of a guarantor or surety or which otherwise might limit
     recourse against the Company or the Guarantor.

     1.3 DISCHARGE. The Guarantor covenants and agrees that this Guaranty will
not be discharged, except by complete performance of the obligations contained
herein. Notwithstanding anything to the contrary herein, so long as the

zero simultaneously with the termination hereof, the Guarantor shall have the
right to terminate this Guaranty at any time by providing written notice of such
termination to the Lender. Notwithstanding any to the contrary, this Guaranty
