Intellectual Property of SIGOS.g.

SIGOS Source Code to a person for such persons internal use only). Schedule 9.11k(2)
identifies each contract pursuant to which SIGOS has deposited, or is or may be required
to deposit, with an escrowholder or any other person, any of SIGOS Source Code, and
describes whether the execution of this Agreement or any of the transactions
contemplated by this Agreement, in and of itself, would reasonably be expected to result
in the release from escrow of any SIGOS Source Code. As used in this Section 9.11k,
SIGOS Source Code means, collectively, any human readable software source code, or any
material portion or aspect of the software source code, or any material proprietary
information or algorithm contained in or relating to any software source code, that
constitutes any SIGOS-Owned IP Rights or any other product marketed or currently

received by Sellers pursuant to Section 14.1 and Sellers do not contest such Notice of

    In the event that Sellers give the Purchaser written notice contesting all or any
