1.  Pursuant to NASA FAR Supplement 1843.7003, the contractor has
    provided a NTE

> cost amount of \$8,400,000 for performance through September 30, 2001.
> The NTE includes only the costs of the mission impacts associated with
> GSFC identified in the February 2000 Mission Set with updates through
> August 15, 2000. The NTE does not include estimates for operations
> impacts as a result of the deletion of the Integrated Mission
> Operations Center. It is understood that any cost over and above the
> "not-to-exceed" cost shall be non-fee bearing unless they arise from
> additional NASA requirements in accordance with NASA FAR Supplement
> 1843.7003.
