pending or, to the Company's knowledge, currently threatened against the Company

is not aware that any of its employees or officers are in violation thereof.
Neither the execution nor delivery of this Agreement, the Investors' Rights
Agreement or the Stockholder Voting Agreement, 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 to be conducted, 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 of such employees is now obligated.

     2.9    Patents and Trademarks.  The Company has sufficient title and
            ----------------------                                       
interest in and to all patents, trademarks, service marks, trade names,

necessary for its business as now conducted and as proposed to be conducted
without any conflict with or infringement of the rights of others.  The Schedule
of Exceptions contains a complete list of patents and pending patent
applications of the Company.  The Company is not aware of any patents,
trademarks, service marks, trade names, copyrights, trade secrets, information,
proprietary rights and processes for which it would need to obtain title and
interest in and to for its business as now conducted and as proposed to be
conducted.  There are no outstanding options, licenses, or agreements of any
kind relating to the foregoing, nor is the Company 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.
The Company has not received any communications alleging that the Company has
violated or, by conducting its business as proposed to be conducted in the
Business Plan, would violate any of the patents, trademarks, service marks,
trade names, copyrights or trade secrets or other proprietary rights 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, that would interfere with the use of his or
her best efforts to promote the interests of the Company or that would conflict
with the Company's business as proposed to be conducted.

     2.10   Compliance with Other Instruments.  The Company is not in violation
            ---------------------------------                                  
or default in any material respect of any provision of the Restated Articles or
its Amended and Restated 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, to its knowledge, of any provision of any federal or state
statute, rule or regulation applicable to the Company.  The execution, delivery
and performance of this Agreement,


                                      5.

 
the Investors' Rights Agreement and the Stockholder Voting Agreement, and the
consummation of the transactions contemplated hereby or thereby 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 such a default under any such
provision, instrument, judgment, order, writ, decree or contract or be 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.

     2.11   Agreements; Action.
            ------------------ 

          (a) Except for agreements explicitly contemplated by this Agreement,
the Investors' Rights Agreement, the Stockholder Voting Agreement or the
Investors Voting Agreement, there are no agreements, understandings or proposed
transactions between the Company and any of its officers, directors, affiliates,
or any affiliate thereof.

          (b) Except for agreements explicitly contemplated by this Agreement or
the Investors' Rights Agreement, there are no agreements, understandings,
instruments, contracts, or proposed transactions, to which the Company is a
party or by which it is bound outside the normal course of business, which may
involve obligations (contingent or otherwise) of, or payments to the Company in
excess of, $100,000.

          (c) The Company has not (i) declared or paid any dividends, or
authorized or made any distribution upon or with respect to any class or series
of its capital stock, (ii) incurred any indebtedness for money borrowed or any
other liabilities individually in excess of $100,000 or, in the case of
indebtedness and/or liabilities individually less than $100,000, in excess of
$250,000 in the aggregate, (iii) made any loans or advances to any person, other

such subsections.

          (e) Since November 30, 1994, the Company has not received notice that
there has been a cancellation of one or more orders for the Company's services

than 1% of the Company's revenues for the fiscal year ended November 30, 1994.
The Company is not aware of any facts or circumstances that would lead it to
reasonably believe that


                                      6.

 
there will be a cancellation of one or more orders for the Company's services or
a loss of one or more customers of the Company, the cancellation or loss of
which in the aggregate would materially adversely affect the business and
prospects of the Company.
