pursuant to those tax returns or otherwise. No such federal, state, local or
municipal tax returns have ever been audited by the Internal Revenue Service,
state or other authorities (except for an audit of state sales and use tax
returns). No deficiency assessment with respect to or proposed adjustment of
any of the Company's Federal, state, municipal or local tax returns has
occurred or, to the Company's knowledge, is threatened (except for a deficiency
assessment following the most recent audit of sales and use tax returns, which
the Company has fully satisfied). There has been no tax lien imposed by any
governmental body outstanding against the business or the Company's assets or
properties, except liens for current taxes not yet due. The reserve for Taxes

obligated to make contributions to, and does not have and has had no liability
with respect to, any Employee Benefit Plan which is: (i) subject to Title IV of
ERISA or the minimum funding requirements of Section 412 of the Code or Section
302 of ERISA, (ii) a "multi-employer plan" (as defined in Section 3(37) of
ERISA), (iii) a "multiple employer plan" (as defined in Section 4063 or 4064 of
ERISA), or (iv) a funded vacation pay plan. The Company and its ERISA
Affiliates have, with respect to each Employee Benefit Plan, complied in all

extension of any benefit under any Employee Benefit Plan or any agreement or

penalties under ERISA Section 502(c), (i) or (l), with respect to any Employee
Benefit Plan nor, to the knowledge of the Company, is there a basis for any
such claim. No officer, director or employee of the Company has committed a
material breach of any responsibility or obligation imposed upon fiduciaries by
Title I of ERISA with respect to any Employee Benefit Plan. Other than routine
claims for benefits, there is no claim pending or, to the knowledge of the
Company, threatened, involving any Employee Benefit Plan by any Person against
such plan, the Company or any of its ERISA Affiliates. There is no pending or,
to the knowledge of the Company, threatened, proceeding involving any Employee
Benefit Plan before any governmental agency. In accordance with applicable law
and the terms of such plan, each Employee Benefit Plan can be amended or
terminated at any time, without consent from any other party. With respect to
the Employee Benefit Plans, individually and in the aggregate, no event has
occurred, and to the knowledge of the Company, there exists no condition or set
of circumstances in connection with which the Company could be subject to any
liability that is reasonably likely to have a Material Adverse Effect. For

with the Company, or a financing transaction proposal as an alternative to the
transactions contemplated by this Agreement (a "Competing Proposal") in a
manner which is or becomes public and this Agreement is terminated following

Agreement, pay to Purchaser a fee (the "Breakup Fee") in the amount of $500,000
or, if greater, 2.5% of the value of the Company established by a proposed
transaction, if, following the announcement or proposal of a transaction, this

   (b) The Company agrees that the agreement contained in Section 6.02(a) above
is an integral part of the transactions contemplated by this Agreement and that
the Consulting Fee constitutes liquidated damages and not a penalty. If Company

Company shall pay the costs and expenses (including reasonable legal fees and
expenses) in connection with any action, including the filing of any lawsuit or
other legal action, taken to collect payment thereof, together with interest on
the amount of any unpaid amount at the annual rate of four percent (4%) above
the publicly announced prime rate of Citibank, N.A. (or, if lower, the maximum
rate permitted by law) from the date such amount was required to be paid to the
date of payment.

   (c) The Company agrees to reserve 250,000 shares of its Common Stock for
issuance in connection with the exercise of the Breakup Warrant, if the Breakup
Warrant is issued. The obligation to reserve shares in connection with the
Breakup Warrant shall survive termination of this Agreement pursuant to Section
6.03, below, and shall remain binding upon the Company.

   (d) Except as provided otherwise in paragraphs (a) and (b) above and in
Section 6.01, all costs and expenses incurred in connection with this Agreement
and the transactions contemplated hereby shall be paid by the party incurring

   (c) by the Company following a proposal of the type described in Section
6.02(a), by written notice to Purchaser; or

   (d) by either party following a material breach by the other party to this
Agreement, provided that if such breach is curable, this Agreement may only be
terminated if, after ten (10) business days' notice, the party in breach has
not either cured such breach or commenced diligent efforts to cure such breach.

   Termination of this Agreement shall not waive any party of liability for
breaches of this Agreement which occurred prior to termination. If this
Agreement is terminated by Purchaser pursuant to subsection (b) of this Section
6.03, the limitation on expenses payable pursuant to Section 6.01 shall be
$85,000.

   SECTION 6.04 Survival of Agreements. All covenants, agreements,
representations and warranties made in the Transaction Documents or any
certificate or instrument delivered to Purchaser pursuant to or in connection
with the Transaction Documents shall survive the execution and delivery of the
Transaction Documents, the issuance, sale and delivery of the Series B Shares,
the issuance and delivery of the Warrants, and the issuance and delivery of the
Conversion Shares and the Warrant Shares, and all statements contained in any
certificate or other instrument delivered by the Company hereunder or
thereunder or in connection herewith or therewith shall be deemed to constitute
