good and marketable title to its material properties and assets, and has good
title to all its material leasehold interests, in each case subject to no
mortgage, pledge, lien, lease, encumbrance or charge of any kind, other than the
lien of current taxes not yet due and payable. All leases pursuant to which the
Company leases real or personal property material to its business are valid and
effective in accordance with their respective terms, and there exists no
material default on the part of the Company thereunder.

         3.9.     COMPLIANCE WITH OTHER INSTRUMENTS, NONE BURDENSOME, ETC. The

Amendment or By-Laws, of any term or provision of any mortgage, deed of trust,
indebtedness, indenture, contract, agreement, instrument, judgment or decree, or
any order, statute, rule or regulation, in each case where such breach or
violation would have a material adverse effect on the Company. No event or
failure of performance has occurred that, with the passage of time or the giving
of notice, would constitute such a breach or violation by the Company. The
execution, delivery and performance of and compliance with this Agreement, the
Rights Agreement and the Shareholder Agreement and the issuance, sale and
delivery of the Shares and the Common Stock issuable upon conversion of the
Shares do not conflict with, and will not result in a breach or violation of the
terms, conditions or provisions of, or constitute a default (or an event that,
with the giving of notice or passage of time, or both, could result in a
default) under, or result in the creation or imposition of any lien pursuant to
the terms of, the Company's Certificate of Amendment or By-Laws, or any statute,
law, rule or regulation, any state or federal order, judgment or decree, or any
indenture, mortgage, deed of trust, lease or other agreement or instrument to
which the Company, or any of its properties, is subject, in each case where such
conflict, breach, violation, default or lien would have a material adverse
effect on the Company.

         3.10.    LITIGATION, ETC. There is no action, proceeding or
investigation pending or threatened (nor to the Company's knowledge is there a
reasonable basis therefor) against the Company or any of its properties or
assets or that questions the validity of this Agreement, the Rights Agreement or
the Shareholder Agreement, or any action taken or to be taken in connection
herewith. The foregoing includes, without limitation, actions pending or
threatened involving the prior employment of any of the Company's employees,
their use in connection with the Company's business of any information or
techniques allegedly proprietary to any of their former employers, or their
obligations under any agreements with prior employers. The Company is not a
party or subject to the provisions of any order, writ, injunction, judgment or
decree of any court or government agency or instrumentality. No action, suit or
proceeding has been instituted or is threatened by the Company.

or designs, produces or sells any products or product lines that are the same,
similar to or competitive with any activity or business in which the Company is
engaged or proposes to engage; (ii) is a supplier, customer, or creditor of the

conducted or proposed to be conducted. To the Company's knowledge, no employee
is in violation of any term of any employment agreement, proprietary information
agreement, non-competition agreement or any other agreement relating to such
employee's relationship with any previous employer. To the Company's knowledge,
neither the execution nor delivery of this Agreement, the Rights Agreement or
the Shareholder 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 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. 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. The Company is not a party to or bound by any currently effective

                                   SECTION IV

                REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

    Each Purchaser hereby severally represents and warrants to the Company with
respect to the purchase of the Shares as follows:

         4.1.     INVESTMENT EXPERIENCE.  It is aware of the Company's business
affairs and financial condition and has acquired sufficient information about
the Company to reach an informed and knowledgeable decision to acquire the
Shares and the underlying Common Stock.

         4.2.     INVESTMENT INTENT. It is acquiring the Shares and the
underlying Common Stock for investment only for its own account, and not with
the view to, or for resale in connection with, any distribution thereof. It
understands that the Shares to be purchased and the underlying Common Stock have
not been, and will not be, registered under the Securities Act by reason of a
specific exemption from the registration provisions of the Securities Act, the
availability of which depends upon, among other things, the bona fide nature of
the investment intent of such Purchaser as expressed herein.

         4.3.     RULE 144. It acknowledges that the Shares and the underlying
Common Stock must be held indefinitely unless subsequently registered under the
Securities Act or unless an exemption from such registration is available. It is
aware of the provisions of Rule 144 promulgated under the Securities Act which
permits limited resale of shares purchased in a private


                                       6

   8
placement subject to the satisfaction of certain conditions, including, among
other things, the existence of a public market for the shares, the availability
of certain current public information about the Company, the resale occurring
not less than two years after the security was last held by the Company or an
affiliate of the Company, the sale being effected through a "broker's
transaction" or in transactions directly with a "market maker" and the number of
shares being sold during any three-month period not exceeding specified
limitations.


         4.4.                NO PUBLIC MARKET.  It understands that no
public market now exists for any of the securities issued by the Company, and
that the Company has made no assurances that a public market will ever exist for
the Company's securities.


         4.5.                ACCESS TO DATA. It has had an opportunity to
discuss the Company's business, management and financial affairs with the
Company's management and the opportunity to review the Company's facilities. It
has also had an opportunity to ask questions of officers of the Company, which
questions were answered to its satisfaction. It understands that such
discussions, as well as any written information issued by the Company were
intended to describe certain aspects of the Company's business and prospects
which the Company believes to be material, but were not a thorough or exhaustive
description, except as set forth in Section 3 hereof.


         4.6.                AUTHORIZATION. Each of this Agreement, the
Rights Agreement and the Shareholder Agreement when executed and delivered by
such Purchaser will constitute a valid and legally binding obligation of the
Purchaser, enforceable in accordance with its terms, except that the
indemnification provisions of Section 5.7 of the Rights Agreement may be limited
by principles of public policy, and subject to laws of general application
relating to bankruptcy, insolvency and the relief of debtors and rules of law
governing specific performance, injunctive relief or other equitable remedies.

         4.7.                ACCREDITED INVESTOR.  It is an "accredited
investor" within the meaning of Securities and Exchange Commission ("SEC") Rule
501 of Regulation D, as presently in effect.

thereafter occurring. It is further agreed that any waiver, permit, consent or
approval of any kind or character of any breach or default under this Agreement,
or any waiver of any provisions or conditions of this Agreement must be in
writing and shall be effective only to the extent specifically set forth in
