purpose of which is to fund payments to employees of the Company under the

funded with $7.0 million), (b) the funds held by the Trustee, pursuant to that
certain Agreement and Declaration of Trust, dated as of July 6, 2001, by and
between the Company, as settlor, and the Trustee, the purpose of which is to
fund payments to employees of the Company under the Company's Severance Policy
and Paid Time Off and Family Medical Leave Act Policy (the "SEVERANCE TRUST,"
which was originally funded with $7.4 million) plus (c) $1.625 million of
severance payable, if earned, to the six (6) senior executives (not including

the Company's Severance Policy, which amounts were not placed in the Severance
Trust (the "SENIOR EXECUTIVE SEVERANCE"); and, provided further, that the
indemnification provided herein is intended to supplement and enhance (and is
not intended to reduce or to be in lieu of) the rights of indemnity that the
Executive has or may have against the Company, including, but not limited to,
the rights of indemnity afforded the Executive under (i) any other indemnity
documents, agreements or instruments between the Executive and the Company, (ii)

unenforceability of any provision of this Agreement shall affect the other
provisions, and this Agreement shall remain in full force and effect and be

temporary restraining order, temporary or permanent injunction or any other
equitable remedy which may then be available.

condition or provision of this Agreement shall be deemed a waiver of similar or
dissimilar provisions or conditions of this Agreement at the same or any prior
or subsequent time.

          d.   SUCCESSORS; BINDING AGREEMENT. Executive hereby consents and
agrees that the Company may require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or assets of the Company or any division of the Company by
which the Executive is employed to expressly assume and agree in writing to
perform this Agreement in the same manner and to the same extent that the

employ the Executive under the terms hereof. Except in accordance with the
foregoing sentence, this Agreement may not be assigned by the Company. This
Agreement shall inure to the benefit of and be enforceable by Executive's

assigned by the Executive.

          e.   SURVIVAL. Notwithstanding anything to the contrary herein, in the
event of a termination of this Agreement, the provisions of Section 5 and
Section 10.b. above shall survive and be enforceable in accordance with their
terms.

          f.   ENTIRE AGREEMENT. From and after the Effective Date, this
Agreement supersedes all prior agreements, negotiations and understandings of
any kind with respect to the subject matter hereof (including Executive's offer
letter, dated as of February 28, 2000, and Executive's Original Agreement) and
constitutes the entire understanding and agreement between the Parties hereto
with respect to the subject matter hereof. Any representation, promise or
condition, whether written or oral, not specifically incorporated herein, shall
be of no binding effect upon the Parties.
