in this Agreement, as of the Independence Date, or other later date that applies
to the particular Tality Plan established thereafter, the Tality Plans shall be,
with respect to Tality Transferred Employees, in all respects the successors in
interest to, and shall not provide benefits that duplicate benefits provided by,

recognition and credit and be taken into account under such Tality Plan to the
same extent as if such items occurred under such Tality Plan, except to the

provisions shall be subject to any respectively applicable "service bridging,"
"break in service," "employment date," or "eligibility date" rules under the
Tality Plans and the Cadence Plans.

of the parties that the Partnership and/or the appropriate Tality Plan shall
assume all Liabilities of the corresponding Cadence Plan to or relating to
Tality Transferred Employees, as provided for herein. If any such Liabilities
are not effectively assumed by the Partnership and/or the appropriate Tality
Plan, then the amount of transferred Assets shall be recomputed accordingly,
taking into account the retention of such Liabilities by such Cadence Plan, and
Assets shall be transferred from the Partnership and/or the appropriate Tality
Plan to Cadence and/or the appropriate Cadence Plan so as to place the
Partnership and/or the appropriate Tality Plan in the position it would have
been in had the initial Asset transfer been made in accordance with such
recomputed amount of assets.

          Section 2.6 DISPUTE RESOLUTION. To the extent disputes arise between
Cadence and any member of the Tality Group regarding management of the Plans,

manner that is consistent with comparable U.S. matters, issues or Liabilities as
reflected in this Agreement (to the extent permitted by Applicable Law or as
otherwise specified in the applicable Section or Schedule).

either plan. Cadence shall amend the plans as necessary to achieve the effects
and results contemplated by this Article IV.

guideline or any agreement or policy pertaining to confidential or proprietary
information of any member of the Cadence Group, or otherwise relieve any
individual of his or her obligations under such non-competition guideline,
agreement, or policy.

from their participation in the Tality Business or employment by the Tality
Group (other than those matters addressed by Section 3.1 of the Assignment
Agreement).

          (b)       UNSCHEDULED CLAIMS. Subject to Section 9.9(a), on or after
