     ASSUMPTION AGREEMENT dated as of October 30, 1998 from Camber

Business Combination Agreement dated as of October 9, 1998 (the "Combination

Agreement.  Capitalized terms used herein but not defined herein shall have
the meanings assigned such terms in the Combination Agreement.

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the Purchaser hereby agrees

of the Seller to the extent attributable to the operation of the Business for
the period commencing on and subsequent to the date hereof (collectively, the
"Assumed Liabilities"):

     a.  liabilities and obligations reflected on the Latest Balance Sheet (but
only to the extent so reflected);

     b.  all liabilities arising after the date of the Latest Balance sheet in
the ordinary course of the Business (which in the aggregate shall not be
material);

     c.  all liabilities and obligations of the Seller under the Contracts set
forth on Schedule G-2-1 attached hereto, excluding any liability for breach or
non-performance of any such existing on or prior to the Closing Date; and

     d.  all liabilities and obligations of the Business arising after the
Closing Date.

     2.  Notwithstanding anything contained in Section 1 hereof to the contrary,
the Purchaser does not assume, and shall not be responsible for, the Excluded
Liabilities and any liabilities or obligations of the Seller or any affiliate of
the Seller, whether fixed or contingent, known or unknown, threatened, pending
or unasserted, other than the Assumed Liabilities.

     3.  From time to time after the date hereof, the Purchaser will execute and
deliver, or cause its affiliates to execute and deliver, to the Seller such
instruments as may be reasonably requested by the Seller or its counsel in
order to carry out the purpose and intent of this Assumption Agreement and 
the Combination Agreement.

     4.  Notwithstanding any other provision of this Assumption Agreement to
the contrary, nothing contained in this Assumption Agreement shall in any way
supersede, modify, replace, amend, change, rescind, waive, exceed, expand,
enlarge or in any way affect the provisions, including the warranties, 
covenants, agreement, conditions, representations or, in general any of the
rights and remedies, and any of the obligations and indemnifications of the
Purchaser set forth in the Combination Agreement nor shall this Assumption
Agreement expand or enlarge any remedies under the Combination Agreement
including without limitation any limits on indemnification specified therein.
This Assumption Agreement is intended only to effect the transfer of certain
liabilities assumed pursuant to the Combination Agreement and shall be governed
entirely in accordance with the terms and conditions of the Combination
Agreement.

     IN WITNESS WHEREOF, the Purchaser has caused this Assumption Agreement
to be executed and delivered on the date and year first written above.
