INTERNAL ASSOCIATE QUESTIONS
Note: The following questions and answers are for internal use only.

For additional information related to highlights of the deal, please see the press release and acquisition fact sheet.

Q: How will this deal affect me?
A: We all appreciate your hard work over the past few weeks despite all the speculation in the media. We know it can be difficult to stay focused on your work when it seems like everyone is discussing your future. We are committed to making the integration and transition as smooth as possible for associates of both firms, and will keep you informed on any decisions that affect you, and we will do that honestly and with respect.

Q: Will positions at either company be eliminated or changed?
A: We recognize that news like this can cause a great deal of uncertainty both professionally and personally. Ameritrade and TD Waterhouse are committed to treating all associates fairly, honestly and with respect. We recognize and appreciate your efforts during this challenging time.

While we will work to minimize job loss through attrition and by limiting external hiring, the reality is that we expect there will be staff reductions. This job loss will primarily occur in the areas where we have overlapping operations. No matter what the situation, Ameritrade and TD Waterhouse are committed to treating all associates fairly, honestly and with respect.

The transaction is expected to close within approximately six months. It is business as usual until then and no job reductions related to the merger are planned prior to the deal closing. Between now and the close of the deal, an integration team of senior management from both companies will review the future needs of the new TD Ameritrade. Your expertise, skills and the relationships you’ve built will be invaluable as we move forward, and clients will continue to need the high level of service you provide.

Q: Why are we doing this deal now?
A: This is the best deal at this time. We believe the combination will provide an opportunity for significant net income growth with minimal exposure to credit or interest rate risk. It will create an even stronger platform for future consolidation and growth.

Together, we will create the largest online retail broker as measured by the average number of retail equity trades per day, with the scale, breadth and financial strength to be a leading player in the increasingly competitive and consolidating investor services industry. The combination of Ameritrade’s industry-leading active trading platform with TD Waterhouse U.S.A.’s extensive investing solutions will create a full spectrum of financial services for all clients.

Q: When will the acquisition be completed?
A: The acquisition requires regulatory and Ameritrade shareholder approval before it can be finalized, and that will take time. The companies expect the transaction to close within approximately six months.

Q: Who is the management team? Who will be on the Board of Directors?
A: Joe Moglia will become chief executive officer of the combined company.

The initial board of directors will include J. Joe Ricketts, Ameritrade founder and chairman of the combined company, vice-chairman Ed Clark, the CEO of TD Bank Financial Group, TD Ameritrade CEO Joe Moglia, J. Peter Ricketts, president and chief operating officer of TD Ameritrade and Thomas S. Ricketts. The remaining TD representatives and three independent members will be selected prior to closing.

Q: What will happen to the company name?
A: The combined company will operate under the name TD AMERITRADE. We will work closely to analyze and determine the best way to leverage the value of both existing brands to ensure that trademarks and trade names are used to bring maximum benefits to the new company and its clients. Please remember that until the transaction is approved and closes, the two firms will continue to compete in the marketplace. No branding or changes that might affect clients or shareholders will be made before that time.

The goal is to bring the best of both brands together to create a recognizable brand that will have greater meaning and relevance to investors.

Q: What executives were involved in this decision?
A: The terms of this transaction were negotiated by TD Bank Financial Group and Ameritrade with the support of senior management teams from Ameritrade, TDBFG and TD Waterhouse.

Q: Is regulatory and shareholder approval necessary? How will the TD Waterhouse and Ameritrade business be run during the regulatory and shareholder approval process?
A: Yes, the deal requires regulatory and Ameritrade shareholder approvals before it can be finalized. We estimate that this transaction will close in approximately six months.

For both Ameritrade and TD Waterhouse, it will be business as usual until full regulatory and shareholder approval is achieved. Both companies need to focus on continuing to serve their clients and achieving their business goals and objectives.

Q: Who will represent TD Waterhouse interests during the transition period?
A: A transition team comprised of senior managers from Ameritrade and TD Waterhouse USA will be established to lead integration following the closing of the transaction. Our goal is to make the integration experience as seamless as possible for clients and associates. Ameritrade has a strong track record of doing just that, having successfully integrated seven companies since 2001. Integration will be organized into phases and could take up to 18 months to complete once the transaction closes.

Q: Will Ameritrade and TD Waterhouse discontinue their advertising and promotional programs?
A: Until the deal closes, the two companies will operate as separate entities. Both Ameritrade and TD Waterhouse will each continue to promote their respective company in the same manner as before the deal.

Q: What will happen to the leadership of Ameritrade and TD Waterhouse USA?
A: We are committed to building a team comprised of the best leaders from both organizations. The goal is to leverage talent from both companies when possible and to combine the best products, systems and processes.

Q: What business functions will be eliminated as a result of the transaction?
A: We can’t speculate on what may happen after the transaction closes, but it is clear that TD Waterhouse U.S.A.’s branches and independent financial advisor businesses complement Ameritrade’s business model. As in any transaction of this nature, it is likely there will be staff reductions where duplicate operations exist.

Q: How will Ameritrade and TD Waterhouse associates receive information as the transaction progresses?
A: It’s a priority for us to keep you informed as the transaction progresses. Regular updates will be posted on the “What’s New” section of the TDW intranet homepage and Announcements section of Athena, Ameritrade’s intranet. Senior managers will also provide regular updates to their teams.

Q: Will associates be entitled to severance if their positions no longer exist? Will current compensation and benefits change for TD Waterhouse associates prior to the transaction being approved?
A: Between now and the approval of the transaction, it is business as usual at both firms. This means that all compensation, benefit and associate policies will operate as they normally do. Associates who are left without a job in connection with the merger will be eligible to receive severance packages. Both Ameritrade and TDBFG are committed to treating associates fairly and with respect.

Q: Will current compensation including bonuses, health benefits, retirement plans, vacation allocations, medical and other leaves change for Ameritrade or TD Waterhouse associates as a result of the transaction?

A: Between now and the approval of the transaction, it is business as usual at both TD Waterhouse and Ameritrade. Associates will continue to receive compensation, benefits and vacation allocations according to the plans in effect at their company until a deal is approved. If there are any changes to the compensation, benefits, retirement plans, vacation allocations of associates who remain with the new company, information will be

provided to associates prior to any changes taking effect. Any existing medical or other leave arrangements will be honored.

Q: Will TD Waterhouse U.S.A. associates still receive their bonus if the deal closes before bonuses are paid?
A: All bonus arrangements will be honored for eligible, qualified associates for the current year.

Q: When will Ameritrade be onsite at TD Waterhouse U.S.A.?
A: As the integration team develops their plans, we will share information about when Ameritrade will be onsite.

Q: Where can I get more information about Ameritrade?
A: You can learn more about Ameritrade and their client offerings at www.ameritrade.com and www.ameritradeinstitutional.com. Corporate and investor information is also available at www.amtd.com. Fact sheets for both companies can be found on www.amtd.com.
