         NOW, THEREFORE, the parties hereto agree as follows:

         1.       ENGAGEMENT. The Company hereby engages the Contractor as a
nonexclusive contractor to perform the Services (as defined herein) subject to

of this Agreement and any and all applicable laws and regulations. The
Contractor acknowledges that this is a nonexclusive engagement by the Company
and that the Company retains the right to appoint additional contractors as the
Company, in it sole and unrestricted judgment, may from time to time determine
to be in the best interests of the Company without liability or obligation to
the Contractor.

         2.       SERVICES.

                  a.       The Contractor agrees to provide finance and business
development services for the Company and perform other duties related thereto as

governmental or regulatory agency without the express prior written
authorization of the Company. In addition all files, books, accounts, records
and other information of any nature, however recorded or stored, and related to
the Company (the "Records") shall at all times belong to the Company and to the

moral turpitude, (ii) improperly performs or fails to perform the Services

Company shall pay to the Contractor the amounts agreed to from time to time by

5 unless required by law. In addition, the Contractor shall be reimbursed for
all expenses incurred by the Contractor on behalf (and with the prior written
authorization) of the Company within 15 days from the date the Contractor

         11.      INDEPENDENT CONTRACTOR.

                  a.       Acknowledgment by Contractor. Contractor acknowledges
                  and agrees that Contractor will be treated, vis-a-vis the
                  Company as an independent contractor and not as an employee,
                  agent or authorized representative of the Company. Contractor
                  shall have no authority to bind the Company to any contract,
                  agreement or obligation whatsoever. The acts of Contractor
                  shall in no way constitute the acts of the Company and
                  Contractor shall not represent to any third party that
                  Contractor has any express or implied authority to bind the
                  Company to any such contract, agreement or obligation.

                  b.       Tax Matters. Because Contractor is an independent
                  contractor, the Company will not withhold from any
                  compensation paid to Contractor any amounts for federal
   4
                  or state income taxes, or social security (FICA) for
                  Contractor, nor will the Company pay any social security or
                  unemployment tax with respect to Contractor. Such taxes are
                  the responsibility of Contractor. Contractor agrees to
                  indemnify and hold the Company (including its employees,
                  officers, directors, agents, subsidiaries or affiliates)
                  harmless, and hereby indemnifies and hold the Company
                  harmless, from and against any damage, claim, assessment,
                  interest charge or penalty incurred by or charged to the
                  Company as a result of any claim, cause of action or
                  assessment by any federal or state government or agency for
                  any nonpayment or late payment by Contractor of any tax or
                  contribution based upon compensation paid hereunder or because
                  the Company did not withhold any taxes from compensation paid
                  hereunder.

                  c.       No Insurance. Consistent with Contractor's status as
                  an independent contractor, the Company will not provide
                  Contractor with any company, individual or group insurance
                  policy or any other kind of insurance coverage whatsoever.

         12.      ASSIGNMENT. Neither this Agreement or any interest herein or
any rights hereunder shall be sold or assigned by the Contractor, nor shall any
of the duties of the Contractor hereunder be delegated to any person, firm or
corporation, without prior notice to and consent of the Company.

         13.      INTELLECTUAL PROPERTY. Any inventions, copyrights, or other
intellectual property created or developed by Contractor or Contractor's
employees, or associates or sub-contractors during the term of this Agreement
related to the work performed under the Agreement shall be assigned to the
Company.

         14.      STANDARD OF CARE. The Contractor warrants that he will
exercise due diligence to perform the Services in a professional manner in
compliance with all applicable laws and regulations and the highest ethical
standards. In addition the Contractor represents and warrants that any
information which he may supply the Company during the term of this Agreement
(i) will have been obtained by the Contractor lawfully and from publicly
available sources' and (ii) will not be confidential or proprietary to any third
person. Nothing in this Agreement shall be construed as authorizing or
encouraging the Contractor to obtain information for the Company in violation of
any third party's rights to copyright or trade secret protection,

         15.      MISCELLANEOUS.

                  a.       The provisions of this Agreement may be waived,
altered, amended or repealed, in whole or in part, only on the written consent
of the Company and the Contractor.

                  b.       Section headings and numbers used in this Agreement
are included for convenience of reference only, and, if there is any conflict
between any such numbers and headings, and the text of this Agreement, the text
shall control. Each of the statements set forth in the premises of this
Agreement is incorporated into the Agreement as a valid and binding
representation of the party or parties to whom it relates.

                  c.       This Agreement shall be governed by and construed in
accordance with the laws of the State of North Carolina without reference to the
choice of law principles thereof. If any
   5
dispute arises hereunder, the parties hereto agree that any suit brought by
either party shall be heard in the courts of North Carolina or any federal court
sitting in North Carolina, and the parties hereto consent to the jurisdiction of
such courts.

                  d.       This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

                  e.       This Agreement, together with the Nondisclosure and
Noncompetition Agreement herein referenced represent the entire agreement of the
parties with respect to the subject matter hereof and supersede in their
entirety any and all prior written or oral agreements with respect thereto.

                  f.       Neither party shall have the right under this
Agreement to use the name, trademark or trade names of the other, unless prior
written approval has been obtained. Any such approval or authorization shall
cease upon termination of this Agreement.

                  IN WITNESS WHEREOF, the duly authorized representatives of the
parties have executed this Independent Contractor Agreement as of the date and
year first above written.
