                                    AMENDMENT

This Amendment, effective upon the execution by both parties, is between LUCENT
TECHNOLOGIES INC. ("LUCENT"), a Delaware corporation, having an office at

WHEREAS, the parties have also entered into a Joint Development Agreement
("Joint Development Agreement") for Process Technologies effective July 31,
2000; and

WHEREAS, the parties wish to amend the term and the scope of patent rights
granted under the Patent License Agreement such that they are consistent with
the Joint Development Agreement;

NOW THEREFORE, the parties agree to amend the Patent License Agreement as
follows:

1.   Revise the definition of CSM's PATENTS as follows:

     In subparagraph (1), change the date from January 1, 2003 to January 1,
     2006.

2.   Delete the definition of LIMITED PERIOD in its entirety and replace it with
     the following:

     Agreement and the Joint Development Agreement have terminated.

3.   Revise the definition of LUCENT's PATENTS as follows:

     In subparagraph (1), change the date from January 1, 2003 to January 1,

     The rate of **** is a discounted rate chosen at the time of execution of
     the Patent License Agreement in 1998 to account for the future
     circumstances of the parties. The parties acknowledge that either of
     the parties may wish to consider a review of the terms of this
     Section 2.02(b)(2) and Section 2.01. Therefore, the parties agree that
     anytime after January 1, 2002, upon written request of one of the parties,
     the parties will review the terms of this Section 2.02(b)(2) and Section
     2.01 and consider making changes thereto, where appropriate. Such review
     will be conducted in good faith, provided, however, that no change shall be
