                      SERVICES PROVIDED AND FEE SCHEDULE

Services & Fees

INFLOW grants Customer a license to install its equipment in INFLOW's Data
Center. Customer may use the space only for the purposes of installing,
maintaining and operating its equipment. Customer has not been granted any real
property interests in INFLOW's premises. INFLOW will provide the following
services:

1.   Installation Services

     a.          Cabinet Installation. In conjunction with Customer's
           representatives INFLOW shall install equipment in Customer-supplied
           cabinets and connect equipment to building ground, electrical power
           circuits and telephony cabling in support of Customer's use of Data
           Center Services. Equipment shall not place a load upon the floor of
           INFLOW's data center which exceeds 100 pounds per square foot.

     b.    Network Installation. [Intentionally Deleted]

2.   Colocation Services

     a.          Cabinet Space. INFLOW shall provide a conditioned environment
           including adequate UPS and generator-protected electricity, air
           conditioning and humidification for seven (7) Customer cabinets to be
           installed in locations that are numbered T7, U7, V7, W7, X7, Y7, Z7
           according to INFLOW's numbering scheme for the Data Center no later
           than 15 September 1998 at INFLOW's Denver data center.

     b.          Right of First Refusal. Customer shall have a right of first
           refusal for additional cabinet locations as follows. Initially,
           Customer shall have a right of first refusal for the five (5) cabinet
           locations that are numbered 07, P7, Q7, R7, S7 according, to INFLOW's
           numbering scheme for the Data Center. Customer's right of first
           refusal for each individual cabinet location shall be for a term of
           eighteen (18) months. If INFLOW desires to make available to another
           customer a cabinet location subject to Customer's right of first
           refusal, INFLOW shall notify Customer of such desire in writing. If
           Customer chooses to exercise its right of first refusal for such
           cabinet location, Customer shall give written notice to INFLOW within
           ten (10) business days after Customer's receipt of INFLOW's notice.
           Customer shall immediately thereafter become obligated for full
           payment for such cabinet location, at the same price as Customer then
           pays for its other cabinet locations under this Agreement. If
           Customer does not notify INFLOW within the time period required
           above, then Customer's right of first refusal for such cabinet
           location will terminate and INFLOW shall have no further obligation
           whatsoever to Customer with respect thereto. Upon Customer's exercise
           of its right of first refusal for any cabinet location, if and only
           if an additional cabinet location remains available in the Data
           Center for offer to new customers, then an additional cabinet
           location shall become subject to Customer's right of first refusal
           under the terms set forth above, so that Customer shall continue to
           have a right of first refusal on the same total number of cabinets as
           existed prior to such exercise. Customer shall identify the
           additional available cabinet location by notice to INFLOW given no
           later than ten days after such exercise. If Customer fails to
           identify an additional cabinet location as required above, INFLOW
           shall have the right to identify such additional cabinet location for
           Customer and will provide notice of the same to Customer.

                            SERVICE LEVEL AGREEMENT


INFLOW's Service Level Agreement defines the performance criteria to which
INFLOW will be held accountable, reporting methods and compensation in the event
that performance levels are not met. Performance levels have been established
for On-Time provisioning, network availability, power availability, and network
time to restore.


On-Time Provisioning

(Intentionally Deleted]


Network Availability
--------------------

[Intentionally Deleted]


Power Availability
------------------

Performance Criteria: Power shall be continuously available 100% of the time to
Customer's cabinet interface each month provided however that INFLOW shall be
allowed a maximum of five (5) minutes of power system maintenance per month.
INFLOW maintenance activities are not intended to disrupt power service. This
service level does not apply to Customer owned/provided equipment in a Cabinet.

Reporting Methods: INFLOW shall provide the Customer a report the start time,
stop time and duration of power outages within 15 calendar days of the end of
each month. The power availability rate shall be calculated based on dividing
the total amount of time without power outages by the total amount of time in
the month.

Compensation: In the event that INFLOW fails to meet the power availability
service level, INFLOW shall credit Customer's bill in the amount equal to 100%
of one month's power usage charge for the cabinet(s) involved.
