     (f) Prior to Siemens dispatching a Siemens CSE to a customer site, as
described in Section 14(b)(iii) above, Siemens shall notify Stereotaxis'
technical support staff and obtain its approval to render such service. In the
event that Stereotaxis fails to respond to Siemens within one (1) hour of such
notification, then Siemens will proceed to render such services. If Siemens
dispatches a CSE to the customer site before receiving the approval of
Stereotaxis or, in the absence of any such approval, before the expiration of
the one (1) hour period, then Siemens will not bill the travel time to
Stereotaxis. The response time for Siemens to provide to any customer the
services described in Sections 14(b)(i) through 14(b)(iii) inclusive shall not
exceed 4 hours during the customer's principal coverage period; provided,
however, that the time during which Siemens is waiting for Stereotaxis' approval
to dispatch a CSE to the customer site shall not count towards the 4 hours'
response time requirement.

     15.  STEREOTAXIS TECHNICAL SUPPORT.

     (a) Stereotaxis will provide 24x7 hours technical support to Siemens' CSEs.
The initial support plan is as follows:

               telephone number.

          o    This number will ring at key personnel's desks in St. Louis
               during regular work hours. If the line is not answered within 4
               rings or it is after regular business hours, the call will
               forward to an answering service.

          o    The answering service will page the on-call service support
               engineer.

               receipt.

          o    Technical support will log all inbound calls including all
               pertinent information such as date, time, customer, problem
               description, problem resolution, etc.

     (b) After Stereotaxis has completed a sufficient number of sales of
Stereotaxis Products, Stereotaxis will investigate the following alternatives
based upon the service needs/frequency of calls/installed base requirements
gathered during the initial sales phase. The preferred option of Stereotaxis
will be discussed and agreed by Siemens before implementation:

     o    Option 1. Establish a dedicated support staff that are available 24x7
          hours and are Stereotaxis employees.

     o    Option 2. Outsource technical support to a 3rd party company that is
          staffed 24x7 hours. This will require in depth training for the 3rd
          party company. Maintain a level 3 support response on an as required
          pager basis.



                                        5
<PAGE>

     o    Option 3. Should after hours support needs be low as the mean time
          between failures ("MTBF") is found to be very high, Stereotaxis may
          elect to stay with after hours technical support provided on an as
          required pager basis.

     16. SPARE PARTS LOGISTICS. All spare parts necessary to repair the
Stereotaxis Products shall be provided to Siemens at no charge.

parts in the United States. Spare parts will be defined and assigned Stereotaxis
and Siemens part numbers according to service needs and requirements. Returnable
parts will be marked with "REP". Spare parts inventory levels will be determined
by Stereotaxis. At a minimum Stereotaxis will review inventory levels annually
and make any necessary adjustments based upon usage. If Siemens elects, it can
stock above the inventory level established by Stereotaxis by purchasing
additional parts from Stereotaxis. Stereotaxis will reimburse Siemens for parts
used from this additional inventory level.

     (c) PARTS ORDERING AND ORDER FULFILLMENT. For the Siemens CSE, the process
for order processing and fulfillment will be the same as for Siemens parts:

          o    Siemens CSE identifies the need for replacement part(s) and
               places an order as with Siemens spare parts.

          o    The order is processed by Siemens and shipped by the order
               processing and fulfillment center.

          o    Certain pre-selected parts, based upon cost or complexity,
               require pre-approval by Stereotaxis' service personnel to ensure
               complete and accurate troubleshooting has been conducted.

          o    Siemens ships returnable parts (REP) to Stereotaxis.

          o    Stereotaxis repairs returned parts as appropriate and returns
               them to service stock.
