investigation (collectively, a "Suit") pending or, to the Company's knowledge,

currently threatened against the Company or any of its subsidiaries that
questions the validity of the Agreements or the right of the Company to enter
into them, or to consummate the transactions contemplated hereby or thereby, or
that might result, either individually or in the aggregate, in any material
adverse changes in the assets, condition or affairs of the Company, financially
or otherwise, or any change in the current equity ownership of the Company, nor
is the Company aware that there is any basis for the foregoing. For the purposes
of this Section 2.7, "Suit" shall include but not be limited to any action,
                      ----
suit, proceeding or investigation pending or, to the Company's knowledge,
currently threatened against the Company involving the prior employment of any

employees' former employers, such employees' obligations under any agreements

Company or any of its subsidiaries currently pending or which the Company or any

         2.8  Intellectual Property.  To its knowledge, the Company owns or
              ---------------------
possesses sufficient legal rights to all patents, trademarks, service marks,

rights and processes necessary for its business without any conflict with, or
infringement of, the rights of others. The Company has not received any
communications alleging that the Company 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. 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 such employee's best efforts to promote the interest of the Company
or that would conflict with the Company's business. Neither the execution or
delivery of this 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,
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.
The Company does not believe 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.

                                                                             -4-
<PAGE>

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

              (a) The Company is not in violation or default of any provisions
of its Restated Certificate or Bylaws or 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 federal or state statute, rule or regulation
applicable to the Company. The execution, delivery and performance of the
Agreements 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 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.

              (b) To its knowledge, the Company has avoided every condition, and
has not performed any act, the occurrence of which would result in the Company's
loss of any right granted under any license, distribution agreement or other
agreement.

$50,000, (ii) the license of any patent, copyright, trade secret or other
proprietary right to or from the Company or any of its subsidiaries, or (iii)
the grant of rights to manufacture, produce, assemble, license, market, or sell

              (c) Neither the Company nor any of its subsidiaries has (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 incurred any other liabilities individually
in excess of $50,000 or in excess of $200,000 in the aggregate, (iii) made any
loans or advances to any person, other than ordinary advances for travel

rights, other than the sale of its inventory in the ordinary course of business.

              (d) The Company has not engaged in the past three (3) months in

power of the Company would be disposed of, or (iii) regarding any other form of

         2.11  Due Diligence.  The Company has fully provided the Purchasers
               -------------
with all the information that the Purchasers have requested for deciding whether
to acquire the Stock including certain of the Company's projections describing
its proposed business (collectively, the "Business Plan"). To the Company's
                                          -------------
knowledge (after reasonable investigation), no representation or warranty of the
Company contained in this Agreement and the exhibits attached hereto, any
certificate furnished or to be furnished to Purchasers at the Closing contains
any untrue statement of a material fact or omits to state a material fact
necessary in order to make the statements contained herein or therein not
misleading in light of the circumstances under which they were made. To the
extent the Business Plan was prepared by management of the Company, the Business
Plan and the financial and other projections contained in the Business Plan were
prepared in good faith; however, the Company does not warrant that it will
achieve such projections.

         2.12  No Conflict of Interest.  The Company is not indebted, directly

relocation expenses of employees. To the Company's knowledge, none of the
Company's officers or directors, or any members of their immediate families,
are, directly or indirectly, indebted to the Company (other than in connection
with purchases of the Company's stock) or have any direct or indirect ownership
interest in any firm or corporation with which the Company is affiliated or with
which the Company has a business relationship, or any firm or corporation which
competes with the Company except that officers, directors and/or stockholders of
the Company may own stock in (but not exceeding two percent of the outstanding
capital stock of) any publicly traded companies that may compete with the
Company. To the Company's knowledge, none of the Company's officers or directors
or any members of their immediate families are, directly or indirectly,
interested in any material contract with the Company. The Company is not a
guarantor or indemnitor of any indebtedness of any other person, firm or
corporation.

         2.13  Rights of Registration and Voting Rights.  Except as contemplated
               ----------------------------------------
