scheduling interruption resulting from Client's delay in which case such delay

     of a third party, XCare.net shall have the right at its sole option and
     expense to (i) substitute or modify the XCare.net Software so that it is
     non-infringing and qualitatively and functionally equivalent to the
     XCare.net Software; (ii) obtain for Client a license to continue using the

law or in equity, the right to seek injunctive relief to enjoin any breach or
violation of this Article IX.
