In the event that AGMI does not have sufficient cash to pay the administrative
claims in full on the Effective Date, the administrative expense claims will,

If AGMI moves to assume the unexpired leases and executory contracts, the claims
shall be treated in accordance with the order of the Court granting the
assumption.  Any unexpired leases or executory contracts for which a Motion to
Assume has not been filed by AGMI prior to the hearing on confirmation shall be
deemed rejected.  Under the terms of the lease agreements, in the event that a
lease is rejected, the equipment or property will be returned to the lessor,
unless AGMI and the lessor otherwise agree.  Any Class 42 claimant asserting a
claim for damages arising from rejection of a lease shall file a proof of claim
with the Bankruptcy Court by the later of the Effective Date or thirty days
after entry of the Order granting the Motion to Reject or the claim shall be
forever barred.  The claims held by holders of rejected leases or executory
contracts shall be treated as a Class 49 unsecured claim subject to the
limitations of Section 502 of the Code.

believes that the bonds will be sufficient to satisfy the Class 44 claim in
full.  To the extent that the bonds are sufficient to pay the allowed claims of
the Class 44 Claimant in full, the Class 44 Claimant is unimpaired.  To the
extent that the bonds are insufficient to pay the allowed claims of the Class 44
Claimant in full, the deficiency claims shall be treated as a Class 49 unsecured
claim.

     3.4  Class 46.   Unimpaired Secured Claims of Norwest Bank. Class 46 is
          ---------   ------------------------------------------
comprised of Allowed Secured Claims of Norwest Bank of Colorado which issued a
