B.2 [SUPPLIES OR SERVICES AND PRICES/COSTS]{.underline}

The purpose of this modification (Mod 223) is to restructure the
contract. Modification 100 had converted the contract from term form,
level of effort, to completion form. The parties agreed and agree for
Mod 223 that, for administrative convenience, the term form, level of
effort contract which existed prior to modification 100, and the
completion form contract which existed upon execution of modification
100, and the restructured contract which exists upon execution of this
modification should be segregated into separate contract schedules, with
each being subject to its own independent terms, conditions, and
findings. The parties accordingly further agreed as follows:

1\. This contract is comprised of three schedules, which are hereby
designated as "Schedule A, Term Form, Level of Effort" "Schedule B,
Completion Form Conversion", and "Schedule C, Completion Form
Restructure".

2\. Schedule A consists of (1) all terms and conditions of NAS9-18181
which were in effect prior to the date of Modification 100, and (2) any
changed or additional terms and conditions as may be made or added

Schedule A is:

ESTIMATED COST \$365,758,000

AWARD FEE \$19,397,000

FIXED FEE [\$ 500,000]{.underline}

TOTAL AMOUNT \$385,655,000
