increase the staffing accordingly. The System will be available for a minimum of
eight (8) hours per contracted day. If Client is dissatisfied with Mobile PET
on-site personnel, Client shall promptly notify Mobile PET in writing, setting
forth the specific basis for Client's dissatisfaction. On receipt of this
notice, Mobile PET will promptly review the matter and take any action it
reasonably deems necessary, provided, Mobile PET at all times retains sole
authority regarding its personnel.
