Attached is a draft of an Assignment whereby ECT-PR-C, L.L.C. assigns its
rights and obligations to purchase the Class B Interest in ECT-PR-B, L.L.C. to
Condor.

Please let me have your comments.  A document in the same form will be used to
transfer ECT-WR-C, L.L.C,s rights and obligations to purchase the Class B
Interest in ECT-WR-B, L.L.C. to Condor.
