10. WARRANTY-
    SBTI warrants that its services hereunder will be of a professional quality
    conforming to generally accepted industry standards and practices. Should
    any modifications be made to product or services provided by SBTI that are
    not authorized and executed by SBTI or the original manufacturer shall void
    the warranty.

11. LIMITATIONS ON WARRANTY-
    The warranty above is exclusive and in lieu of all other warranties,
    whether express or implied, including the implied warranties of
    merchantability and fitness for a particular purpose. The stated warranty
    is valid for a period of ninety (90) days from the date of task completion.

12. EXCLUSIVE REMEDY-
    For any breach of the above warranty, Client's exclusive remedy, and
    SBTI's entire liability, shall be the reperformance of the services. In
    order to receive warranty remedies, deficiencies in the services must be
    reported to SBTI in writing within 90 days of completion of those services.
    If SBTI is unable to perform the services as warranted within 45 days after
    notification, Client shall be entitled to recover the fees paid to SBTI for
    such deficient services. This constitutes the sole liability of SBTI.

13. TERMINATION OF AGREEMENT-
    Either party can terminate this Agreement without cause upon thirty (30)
    days prior written notice to the other party. Either party can terminate
    this Agreement for cause if either party considers the other party is not
    performing its obligations according to this Agreement and provides written
    notice to the other party of such non-performance. The party receiving such
    written notice will have fifteen (15) days from the date of notice receipt
    to correct the situation. If this situation is not corrected, the
    Agreement can be terminated immediately upon written notice. Client is
    obligated and agrees to pay for services provided through the date of
    termination.

14. DELAY

    Should the Client delay the Start of the contract, or should the contract
    be terminated without proper notice, the Client agrees to pay for 10 days

    prior to the 10 day period, the Client will be billed only for the idle
    days and not for the full 10 days.

    the SBTI representative is not technically qualified, SBTI will investigate
    the claim and provide substitute personnel to the Client at no additional

    reason other than job performance, a cost may be incurred. This cost will
    be mutually agreed to at the time.

16. FORCE MAJEURE-
    Neither party shall be responsible for any failure to perform or delay in
    performing any of its obligations under this Agreement where and to the
    extent that such failure or delay results from causes outside the
    reasonable control of the party. Such causes shall include, without
    limitation, Acts of God or of the public enemy, acts of the government in
    either its sovereign or contractual capacity, fires, floods, epidemics,
    quarantine restrictions, freight embargoes, civil commotions, or the like.

    an excusable delay for either party under this Agreement. Further, the
    passage of time, especially the change from the year 1999 to the year 2000
    and the year 2000 to the year 2001, will not constitute a force majeure
