service marks, tradenames, copyrights, trade secrets, licenses, information and
proprietary rights and processes necessary for its business as now conducted and
proposed to be conducted as set forth in written materials provided to
Purchasers by the Company without any conflict with, or infringement of, the
rights of others. There are no outstanding options, licenses, or agreements of
any kind relating to the foregoing, nor is the Company or the Subsidiary bound
by or a party to any options, licenses or agreements of any kind with respect to
the patents, trademarks, service marks, trade names, copyrights, trade secrets,
licenses, information, proprietary rights and processes of any other person or
entity, except, in either case, for standard end-user, object code, internal-use
software license and support/maintenance agreements. Neither the Company nor the
Subsidiary has received any communications alleging that the Company or the
Subsidiary has violated or, by conducting its business, would violate any of the
patents, trademarks, service marks, tradenames, copyrights, trade secrets or
other proprietary rights or processes of any other person or entity. Neither the
Company nor the Subsidiary is aware that any of its employees is obligated under
any contract (including licenses, covenants or commitments of any nature) or
other agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of such employee's best
efforts to promote the interests of the Company or the Subsidiary or that would
conflict with the Company's business. Neither the execution or delivery of the
Agreements, nor the carrying on of the Company's business or the Subsidiary's
business by the employees of the Company or the Subsidiary, nor the conduct of
the Company's or the Subsidiary's business as presently proposed, will, to the
Company's knowledge, conflict with or result in a breach of the terms,
conditions, or provisions of, or constitute a default under, any contract,
covenant or instrument under which any such employee is now obligated. Neither
the Company nor the Subsidiary believes it is or will be necessary to use any
inventions of any of its employees (or persons it currently intends to hire)
made prior to their employment by the Company or the Subsidiary, as applicable.

        2.9 Compliance with Other Instruments.
            ---------------------------------

default of any provisions of the Restated Articles, its bylaws (the "Bylaws") or
                                                                     ------
of any instrument, judgment, order, writ, decree or contract to which it is a
party or by which it is bound or of any provision of any federal or state
statute, rule or regulation applicable to the Company or the Subsidiary or the
conduct of its business which violation or default would result in a material
adverse effect on the assets of the Company or the Subsidiary. The execution,
delivery and performance of the Agreements and the consummation of the
transactions contemplated herein or therein will not result in any such
violation or be in conflict with or constitute, with or without the passage of
time and giving of notice, either a default under any such provision,
instrument, judgment, order, writ, decree or contract or an event which results
in the creation of any lien, charge or encumbrance upon any assets of the
Company or the Subsidiary.

            (b) Each of the Company and the Subsidiary has avoided every
condition, and has not performed any act, the occurrence of which would result
