Linn Software has some important announcements to make that will be of interest to all users and prospective users of Investor/RT.

First, Chad L. Payne is assuming a new role at Linn Software. Over the past six months, Chad has applied his considerable talents to the enhancement of the Investor/RT Profile Charts – TPO, Volume Profile and associated technical indicators for use in traditional charting. The rich profile functionality that resulted is attracting a great deal of attention. Chad and I believe there is a significant opportunity to grow our Investor/RT business substantially by focusing our efforts on meeting the needs of traders who require professional quality market and volume profile software. To this end, Chad will head up our efforts in this area. He will continue to have responsibility for product development and support of these advanced capabilities, and he will take on new responsibilities in marketing and business relationship development to promote this portion of our business. We are announcing today, two significant decisions regarding the future deployment of these advanced charting and analysis tools:

Linn Software has entered into an agreement with the Chicago Board of Trade to license the Market Profile Graphic Format® and the associated Market Profile® trademark for use in Investor/RT. The Investor/RT Market Profile software will be available for license effective August 1, 2006 in Investor/RT Version 8.5 to be released by that date. The Market Profile will be an elective feature of the Investor/RT Standard or Professional edition when licensed with a real-streaming data source. The license fee will be $20, a fee that includes end-user license fees payable on behalf of the user to the CBOT for use of the Market Profile Graphic Format. Users subscribing to the Investor/RT Market Profile must execute a CBOT End-User License Agreement. Detailed instructions are on the pricing and ordering page at www.linnsoft.com .

Linn Software has reached an agreement in principle with MarketDelta, LLC (www.marketdelta.com). Under the terms of this agreement, Market Delta will become a licensed distributor of co-branded editions of Investor/RT software, including the Investor/RT Market Profile. Market Delta will become the exclusive distributor of our Volume Profile charting software which integrates perfectly with MarketDelta’s Footprint Chart, a patent pending display format for buy vs. sell volume and market price. The MarketDelta branded editions of Investor/RT will include a Footprint Edition and an edition combining the Footprint with Market Profile. These branded editions of Investor/RT will be available soon to MarketDelta customers in either Standard or Professional configurations.

MarketDelta and Linn Software will cross promote all available editions of Investor/RT. The MarketDelta branded editions will be unique in delivering MarketDelta’s patent pending Footprint volume display format either as a stand alone tool or in an integrated product with Market Profile. New subscribers who want to use these Volume Profile/Footprint charting features will license these branded editions from MarketDelta. Linn Software editions of Investor/RT will not include a Volume Profile chart. Linn Software will offer the Market Profile in the Standard or Professional editions to new and existing Linn Software clients.

Those clients with active subscriptions as of July 21, 2006 who wish to continue using the volume profile charting features may continue as Linn Software customers with the right to transfer their licenses to the appropriate MarketDelta branded edition of Footprint and Market Profile at a preferred monthly billing rate. Subscriptions may continue at the preferred monthly rate until terminated by the user.

This announcements represent a $20/month increase in price for customers who elect to subscribe to the Market Profile. This is in line with our previously announced intention to increase the license fee for these advanced features that have been the focus of much of our developmental efforts for more than six months. The increase is at the high end of expectations in large part because we have elected to pay the end-user Market Profile license fee on your behalf to the CBOT. In addition, these announcements communicate a renewed focus of the company on these capabilities that are essential to your trading methods. You can look forward to continued enhancement, refinement, and top notch support of the Market Profile going forward to meet your needs. Though our new relationship with MarketDelta, we expect to bring Investor/RT software to the attention to a wider audience of traders. The benefits of this collaboration will continue to be available to our existing subscribers at no additional cost beyond this $20 increase. We hope this will help you put the increase in perspective and you will continue to use Investor/RT with the expectation of even greater things to come in the months ahead.
