This message only effects DTN Satellite customers receiving data via Channel A (Non-Velocity). This includes the DTN Spectrum, DTN First Rate and DTN Real-Time services. If your Satellite receiver shows Channel E on it, you are not effected by this notice. We are
removing all Financial futures and currencies data from Channel A because the high volume of these contracts may affect the timely delivery of other quotes, weather and news information. By moving to Channel E (Velocity), you will receive data on a 1.5 MB satellite channel that has the capacity to broadcast this data unfiltered.


Attention DTN Financial Futures Users:

At DTN, we are committed to providing our customers with the most current and useful
information to help you make better trades. Because of this commitment,
we are making some significant changes to our services in the coming weeks.

In order to improve the timeliness of our data to all customers, DTN will be
removing streaming financial futures data from our slower "Channel A" satellite
feed effective September 18, 2004. Subscribers will continue to receive
tick-by-tick agriculture commodity and index quotes as well as snapshot delayed
equities data. We will also provide updates to financial futures and currency
quotes 4 times per day.

Should you wish to continue to receive detailed financial futures and currencies
data, DTN is pleased to offer three options:

1. Upgrade your subscription to our Spectrum Velocity Satellite Service. This
option will provide you identical service to what you receive now, with the
advantage of receiving data through our higher speed velocity channel. We
will need to change your receiver and satellite dish in order to receive this
service.
2. Upgrade your subscription to our DTN Real Time Satellite Service. This options
will provide you the same information you receive now, plus the ability to
receive Real-Time stocks, futures and options data. We will need to change your
receiver and satellite dish to our D8x platform and you will need a computer
with compatible software to read the datafeed. Our DTN.IQ for Satellite software
is included with this service.
3. Switch to our Internet based DTN.IQ or IQFeed services (www.dtniq.com or
www.iqfeed.net)

To learn more about any of these options, please contact our customer support
group at 800-475-4755. You can also email investor@dtn.com or visit www.iqfeed.net
and click on Live Support or Live Sales to chat with us online.

With these changes, you can be assured to continue receiving timely information on the
data you need most.

Sincerely


Jay Froscheiser
Vice President, Product Operations
