         In addition to the above provisions, each Subcontract must contain the
         following:

         To comply with these requirements, AHCCCSA requires all clinical
         laboratories to provide verification of CLIA Licensure or Certificate
         of Waiver during the provider registration process. Failure to do so
         shall result in either a termination of an active provider ID number,
         or denial of initial registration. These requirements apply to all
         clinical laboratories.

         Pass-through billing or other similar activities with the intent of
         avoiding the above requirements are prohibited. Contractor may not
         reimburse providers who do not comply with the above requirements.

         policy or policies of professional liability insurance, comprehensive
         general liability insurance and automobile liability insurance in an
         amount of at least $1,000,000 for each occurrence. Subcontractor agrees
         that any insurance protection required by this subcontract, or
         otherwise obtained by Subcontractor, shall not limit the responsibility
         of Subcontractor to indemnify, keep and save harmless and defend the
         State and AHCCCSA, their agents, officers and employees as provided
         herein. Furthermore, Subcontractor shall be fully responsible for all
         tax obligations, Worker's Compensation Insurance, and all other
         applicable insurance coverage, for itself and its employees, and
         AHCCCSA shall have no responsibility or liability for any such taxes or
