         4. Duties of Consultant. Consultant shall furnish consulting and
advisory services to Employer in connection with acquisition strategy and
implementation. Such services shall be rendered at such times and in such manner
as shall be mutually agreeable to Employer and Consultant.

         5. Compensation. Consultant shall be paid $10,000 per month during the
term of this Agreement.

         6. Relationship of the Parties. In performing its services under this
Agreement, the Consultant shall be an independent contractor and, as between
Employer and Consultant, Employer shall not be responsible for withholding,
collection or payment of income taxes or for other taxes of any nature on behalf
of Consultant. Nothing contained herein shall make Consultant the agent,
employee, joint venturer or partner of Employer or provide Consultant with the
power or authority to bind Employer to any contract, agreement or arrangement
with any individual or entity except with the prior written approval of
Employer.

         7. Assignment. Neither party hereto may assign, without the other
party's prior written consent, this Agreement, or any right or obligation
hereunder, and any and all assignments without such prior written consent shall
be null and void.

         8. Indemnification. The Employer shall indemnify, defend and hold
Consultant harmless from and against any and all losses, claims, damages or
liabilities, joint or several, in connection with any pending or threatened
action, proceeding or investigation to which Consultant may be subject in
connection with the performance by Consultant of his services hereunder; in
addition, the Employer will reimburse Consultant periodically for any reasonable
legal or other expenses (including the cost of any investigation and
preparation) incurred by Consultant and arising from or in connection with any
pending or threatened action, proceeding or investigation, which might give rise
to a claim for indemnification hereunder, whether or not actually resulting in
any liability; provided that Employer shall not be liable under this Section 8
to the extent that a court of competent jurisdiction shall have determined by
final judgment that any such losses, claims, damages, or liabilities resulted
from Consultant's gross negligence or willful misconduct in the performance of
such services; and further provided that (i) Consultant shall have promptly
provided Employer written notice of the commencement of any action, proceeding
or investigation and shall provide reasonable cooperation, information and
assistance in connection therewith, and (ii) Employer shall have sole control
and authority with respect to the defense, settlement, or compromise thereof.
The indemnity contained in this Section 8 shall extend upon the same terms and
conditions to each person, if any, who may be determined to control Consultant
and to any employee or agent of Consultant performing services hereunder. The
provisions of this Section 8 shall survive termination of this Agreement.

operate as a waiver of any other provisions hereof (whether or not similar), nor
shall such waiver constitute a continuing waiver. Except as
