Subject: Ameritrade Advisor Services eNews, November 2005

A Message from Jim Wangsness
Senior Vice President
Ameritrade Advisor Services

November’s eNews includes important updates on the proposed acquisition of TD Waterhouse and information that was shared with clients at PowerSource’05 and the associated Town Hall. If at all possible, we strongly encourage participation in either one of two upcoming webinars listed below so that your voice may be heard and your questions answered.

PowerSource’05
From October 24-26, over 400 attendees participated at PowerSource’05, our annual RIA strategy conference. We thank our RIA clients who made the trip to Washington, DC to be with us.

Town Hall at PowerSource’05:
An important part of PowerSource’05 was the live three-hour Town Hall event before conference kickoff. In attendance were senior members of Ameritrade Advisor Services and also two senior representatives of TD Waterhouse Institutional — Tom Nally, SVP (Client Services & Operations) and Brian Stimpfl, SVP (Business Solutions).

The agenda for the Town Hall was split into four sections as follows:

• Strategic overview of the proposed deal and key dates

• Proposed Client Services migration from Omaha to San Diego and Fort Worth

• Update on Ameritrade Connection and proposed technology plans including Veo (TD Waterhouse Institutional technology platform)

• Products and Services choices in the proposed new organization

The Town Hall also afforded us an opportunity to listen to key advisor feedback that extended throughout PowerSource’05. Tom Bradley, President of TD Waterhouse Institutional participated in the entire PowerSource’05 event specifically for this purpose.

Chronologically, there are three key dates for the acquisition of TD Waterhouse:

1.	Acquisition Close (estimated early calendar 2006) —date the TD Ameritrade deal closes.
2.	Broker Conversion (estimated to be +2 months from the acquisition close) —date on which TD Ameritrade’s new brand will be available including all the branch offices; and

3. Clearing Conversion (estimated to be 10-12 months from the acquisition close) —date on which the new institutional front-end platform will be linked to one enhanced and consolidated back-end processing system.

Organizationally, Tom Bradley has been named to head the combined TD Ameritrade Institutional organization as its Executive VP. Derek Bruton, SVP — Sales of TDW Institutional has been named the National Sales Manager. Other key senior management positions will be announced during the upcoming webinars. As announced at PowerSource’05, I will be leaving the firm at the close of the TD Ameritrade deal. In the interim, I am integrally involved in the transition process and will lead Ameritrade Advisor Services until this date. Note that TD Waterhouse Institutional and Ameritrade Advisor Services continue to be separate and distinct competitors until the acquisition Close.

TD Ameritrade Transition Webinars — November 29^th and November 30^th
Since the majority of our RIA clients could not come to Washington, DC for PowerSource’05 we will be hosting two “live chat” webinars regarding key decisions, upcoming transitional issues, and to continue to seek advisor feedback in the process. The dates are Tuesday, November 29^th at 5:00 pm EST and Wednesday, November 30^th at 12 noon EST. We expect these to run 60-90 minutes each. Since both webinars cover the same topic matter, you only need to attend one. For those unable to make either event, they will be stored on our www.ameritradeinstitutional.com website a week after broadcast. Key participants from Ameritrade Advisor Services include:

• Jim Wangsness, SVP — Business Head of Ameritrade Advisor Services

• Judy Moore, Director — Client Services

• Earl McAlear, Director — Advisor Technology

• Neil Curran, Senior Director & National Sales Manager

• Key transitional Account Management staff including:

• Christian Graham (West Coast),

• Chris Engelbert (Midwest) and

• Scott Fangman (East Coast)

Ameritrade Connection Update
On November 8^th, the next phase of the enhanced functionality of the Ameritrade Connection platform was released. To summarize, its functionality is to assist RIAs with Block Trading and Reviewing Client Account information. The latest release included:

• A new comprehensive view of your clients’ account data including:

• A single page to review Balances & Positions

• A single page to review Transaction History along with Confirms & Statements

• A single page to review the Account’s Profile as well as to change Contact Information (e.g., email, mailing addresses, and phone numbers)

• Block Trade Order entry enhancements including:

• A Segregated Order Management View

• Improved Pre-Allocation and Post-Allocation input process

A webinar to showcase this new functionality was held on Tuesday, November 22^nd. An archive copy will be posted shortly to www.ameritradeinstitutional.com for viewing. If you have any specific questions, please contact Earl McAlear at 443-539-2282 or emcalear@ameritrade.com.

Vendor Discount & Alliance Program Recap
A key finding from PowerSource’05 was that many of our RIA clients were still not aware of the assortment of business partners who offer 10-20% or more discounts as part of our Vendor Discount & Alliance Program. Since being introduced two years ago, over 80 vendors have been added. From planning software (e.g., Morningstar), to portfolio accounting tools (e.g., Investigo), to compliance offerings, and more this program includes vendors most requested by our RIA clients. Any Ameritrade Advisor Services RIA client can take advantage of the program’s benefits at no charge. Please contact Mary Nocita at 402-596-8516 or mnocita@ameritrade.com for more details or visit www.ameritradeinstitutional.com.
