                  with XACCT. The number of Designated Support Contact(s) will
                  be determined by the level of Support Services purchased by

                  substituting or replacing the Designated Support Contact(s).

         (c)      Subject to Licensee's applicable security requirements,
                  provide XACCT with access to and use of all information and
                  system facilities including but not limited to a modem
                  connection to Licensee's systems determined necessary by XACCT
                  to provide timely Support Services pursuant to this Agreement.

         (d)      Follow operating instructions and procedures as specified in,
                  but not limited to, XACCT's documentation and other

                  accordance with XACCT's then current problem reporting
                  procedures and as provided in Attachment 1. If XACCT believes
                  that a problem reported by Licensee may not be due to an error
                  in the Product, XACCT will so notify Licensee. In such cases
                  support additional support fees may be required for support
                  provided by XACCT.

         (a)      altered, damaged or Licensee-modified Product, or any portion
                  of the Product incorporated with or into other software other

                  expressly approved by XACCT in writing;

         (b)      any version of the Product other than the current version of
                  the Product, the immediately previous version and the version

                  to support the version prior to the immediately previous
                  version shall not extend beyond six (6) months after the
                  release of the current Major Release of the Product.

                  control of XACCT; or

                  malfunction of any system, equipment, facilities or devices
                  not furnished by XACCT.
