          2.10 Proprietary Assets.
               ------------------

     The Company has full title and ownership of or licenses to all patents,
patent applications, trademarks, service marks, trade names, copyrights, moral
rights, mask works, trade secrets, compositions of matter formulas, designs,
information, proprietary rights, know-how and processes ("Proprietary Assets")
necessary for its business as now conducted and, except for such items as have
yet to be conceived or developed by the Company or that are expected to be
generally commercially available for licensing on reasonable terms from third
parties, as currently proposed to be conducted, without any conflict with or
infringement of the rights of others, and the Company has taken and in the
future will use its best efforts to take, all steps reasonably necessary to
preserve its legal rights in, and the secrecy of, all its Proprietary Assets.
There are no outstanding options, licenses, or agreements of any kind relating
to the Proprietary Assets, nor is the Company bound by or a party to any
options, licenses or agreements of any kind with respect to the Proprietary
Assets of any other person or entity, except for commercially available end-
user, object code, internal-use software license and support/maintenance
agreements with respect to such proprietary rights of any other person or
entity.  The Company is not obligated to pay any royalties or other payments to
third parties with respect to the marketing, sale, distribution, manufacture,
license or use of any Proprietary Asset or any other proprietary rights.  To the
best of the Company's knowledge, the Company has not violated or infringed, and
is not currently violating or infringing any Proprietary Asset of any other
person or entity.  The Company has not received any communications alleging that
the Company or any of its employees  has violated or infringed or, by conducting
its business as proposed, would violate or infringe any of the Proprietary
Assets of any other person or entity. To the best of its knowledge with respect
to its Proprietary Assets the Company has not violated or, by conducting its
business as currently proposed, would not violate, any of the Proprietary Assets
of any other person or entity. The Company is not 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, or any other restriction
that would materially interfere with the use of his or her best efforts to carry
out his or her duties for the Company or to promote the interests of the Company
or that would conflict with the Company's business as proposed to be conducted.
Neither the execution nor delivery of this Agreement, the Ancillary Agreements,
nor the carrying on of the Company's business by the employees of the Company,
nor the conduct of the Company's business as proposed, will, to the best of the
Company's knowledge, conflict with or result in a breach of the terms,
conditions or provisions of, or constitute a material default under, any
contract, covenant or instrument under which any of such employees is now

                                       7
<PAGE>

obligated. The Company does not believe it is or will be necessary to utilize
any inventions of any of its employees (or people it currently intends to hire)
made prior to their employment by the Company.  To the best of the Company's
knowledge, at no time during the conception or reduction of any of the Company's
Proprietary Assets to practice was any developer, inventor or other contributor
to such patents operating under any grants from any governmental entity or
agency or private source, performing research sponsored by any governmental
entity or agency or private source or subject to any employment agreement or
invention assignment or nondisclosure agreement or other obligation with any
third party that could adversely affect the Company's rights in such Proprietary
Assets.

               ---------------------------------

     The Company is not in violation or default of any provision of its Restated
Certificate or Bylaws, or in any material respect 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 judgement, decree, order, statute,
rule or regulation applicable to the Company. The execution, delivery and
performance of this Agreement and the Ancillary Agreements, and the consummation
of the transactions contemplated hereby and thereby will not result in any such
violation or default or be in conflict with or constitute, with or without the
passage of time and giving of notice, either a material default under any such
provision, instrument, judgment, order, writ, decree or contract or an event
that results in the creation of any lien, charge or encumbrance upon any assets
of the Company or the suspension, revocation, impairment, forfeiture, or
nonrenewal of any material permit, license, authorization, or approval
applicable to the Company, its business or operations or any of its assets or
properties. The Company's business as it is presently conducted is in full
compliance with all applicable federal, state local and foreign laws, rules,
regulations, orders and decrees (collectively, "Laws") applicable to the Company
and/or its properties (including, without limitation, Laws relating to foreign

Agreement such Investor hereby confirms, that the Series C Preferred Stock to be
received by such Investor and the Common Stock issuable upon conversion thereof

Investor's own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof, and that such Investor has no
present intention of selling, granting any participation in, or otherwise
distributing the same. By executing this Agreement, such Investor further
represents that such Investor does not have any contract, undertaking, agreement
or arrangement with any person to sell, transfer or grant participation to such

requested by the Company, such Investor shall have furnished the Company with an
opinion of counsel, reasonably satisfactory to the Company that such disposition
will not require registration of such shares under the Act.

above, no such registration statement or opinion of counsel shall be necessary
for a transfer by an Investor (i) to an Affiliate (as defined in Rule 405 under
the Act; or (ii) that is a partnership to a partner of such partnership or a
retired partner of such partnership who retires after the date hereof, or to the
estate of any such partner or retired partner or the transfer by gift, will or
intestate succession of any partner to his or her spouse or to the siblings,
lineal descendants or ancestors of such partner or his or her spouse, if the
