Except as set forth in Section 4.16(i) of the Ameritrade Disclosure Schedule, there is no contract, plan or arrangement (written or otherwise) covering any current or former employee, director or consultant of Ameritrade or any of its Subsidiaries that, individually or collectively, could give rise to the payment of any amount that would not be deductible pursuant to the terms of Section 280G of the Code or would be subject to excise tax under Section 4999 of the Code.

          SECTION 4.25.  Interest Rate Risk Management Instruments . Neither Ameritrade nor any of its Subsidiaries is a party to any interest rate swaps, caps, floors and option agreements and other interest rate risk management arrangements, whether entered into for the account of Ameritrade or any of its Subsidiaries or for the account of a customer of Ameritrade or any of its Subsidiaries.

          SECTION 4.26.   Labor and Employment Matters .

To the knowledge of Ameritrade, since June 1, 2002, neither Ameritrade nor any of its Subsidiaries has encountered any labor union organizing activity or had any actual or threatened employee strikes, work stoppages, slowdowns or lockouts, other than any such events that would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on Ameritrade. Except with respect to instances that would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on Ameritrade, Ameritrade and each of its Subsidiaries (a) is, and since June 1, 2002, has been in, compliance with all applicable laws relating to employment and employment practices, occupational safety and health standards, terms and conditions of employment and wages and hours, and (b) is not, and since June 1, 2002, has not, engaged in any unfair labor practice.

          SECTION 5.4.   No Solicitations . (a) Ameritrade agrees that neither it nor any of its Subsidiaries shall, and that it shall use all reasonable efforts to cause its and its Subsidiaries’ directors, officers, employees, agents and representatives (including any investment banker, financial advisor, attorney, accountant or other representative or agent (collectively, “ Representatives ”) retained by it or any of its Subsidiaries) not to, directly or indirectly, (i) initiate, solicit or knowingly encourage or facilitate any inquiries or the making of any proposal or offer with respect to, or a transaction to effect, (A) a merger, reorganization, share exchange, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving Ameritrade or any of its Subsidiaries, other than any such merger, share exchange, consolidation or other business combination resulting in or involving (x) the purchase or other acquisition by, or the sale or issuance to, any Person of securities representing (or convertible into or exchangeable for securities that would represent) less than 15% of the total voting power of Ameritrade or any of its Subsidiaries or (y) the purchase or sale of assets representing less than 15% of the aggregate fair market value of the consolidated assets

Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to obtaining the Ameritrade Required Votes and any Additional Votes, Ameritrade receives a bona fide Acquisition Proposal not solicited in material violation of Section 5.4(a) and its Board of Directors (acting upon the recommendation of the Special Committee) concludes in good faith that such Acquisition Proposal constitutes or is reasonably likely to result in a Superior Proposal, Ameritrade may, and may permit its Subsidiaries and its and their Representatives to, furnish or cause to be furnished confidential information or data to the Person making such Acquisition Proposal and participate in negotiations or discussions with such Person regarding such Acquisition Proposal if and to the extent that the Ameritrade Board of Directors (acting upon the recommendation of the Special Committee) concludes in good faith, after consultation with its outside counsel, that failure to take such action would be inconsistent with its fiduciary duties under applicable law; provided that prior to providing (or causing to be provided) any confidential information or data permitted to be provided pursuant to this sentence, Ameritrade shall have entered into a confidentiality agreement with such third party on confidentiality terms no less favorable to Ameritrade than the Confidentiality Agreement, dated November 7, 2004, between TD and Ameritrade (the “ Confidentiality Agreement ”); and provided further , that Ameritrade shall also provide to TD a copy of any such confidential information or data that it is providing to any third party pursuant to this Section 5.4 to the extent not previously provided or made available to TD.

56

other aspects of the proposal and the Person making the proposal (including any break-up fees, expense reimbursement provisions and conditions to consummation), (x) is more favorable to the stockholders of Ameritrade, from a financial point of view, than the transactions contemplated by this Agreement (taking into account the Ameritrade Board of Directors’ good faith assessment of the prospective synergies and cost savings anticipated to be realized from and following the Share Purchase and the other transactions contemplated hereby) and (y) is fully financed or reasonably capable of being fully financed and otherwise reasonably capable of being completed on the terms proposed; provided that for purposes of this definition of “Superior Proposal,” the term Acquisition Proposal shall have the meaning assigned to such term in Section 5.4(a), except that in the definition of “Acquisition Proposal” (i) the reference to “15%” in clauses (A)(y) and (B) shall be deemed to be a reference to “70%” (ii) the reference to “15%” in clauses (A)(x) and (C) shall be deemed to be a reference to “40%” and (iii) in order to qualify as an “Acquisition Proposal” under clauses (A)(x) or (C) a transaction must involve voting securities only of Ameritrade and not of its Subsidiaries or Significant Subsidiaries, as the case may be (other than indirectly through the acquisition of voting securities of Ameritrade) (it being understood that an Acquisition Proposal need only meet any of clauses (A), (B) or (C) of the definition thereof (as modified by the foregoing proviso) in order to be eligible to be determined to be a Superior Proposal as provided above).

          (c) (i) Ameritrade will, and will cause its Subsidiaries to, and will use all reasonable efforts to cause its and their respective directors, officers, employees, agents and Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than TD with respect to any Acquisition Proposal and (ii) Ameritrade will use all reasonable efforts to enforce (and will not release any third party from its obligations under) any standstill, confidentiality or similar agreement relating to an Acquisition Proposal, including by requiring the other parties thereto to promptly return or destroy any confidential information previously furnished by Ameritrade thereunder and by using all reasonable efforts if reasonably requested by TD to seek injunctions or other equitable remedies to prevent or restrain any breaches of such agreements and to enforce specifically the terms and provisions thereof in a court of competent jurisdiction.

          (d) Nothing contained in this Agreement shall prevent Ameritrade or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with

57

respect to an Acquisition Proposal, provided that such Rules will in no way eliminate or modify the effect that any action pursuant to such Rules would otherwise have under this Agreement; and provided , further , that any such disclosure (other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) shall be deemed to be a Change in Ameritrade Recommendation unless the Ameritrade Board of Directors expressly reaffirms the Ameritrade Recommendation in such disclosure.

          (e) Ameritrade agrees that any violation of the restrictions set forth in this Section 5.4 by any director, officer, employee, agent or Representative of Ameritrade or its Subsidiaries, at the direction or with the consent of Ameritrade or its Subsidiaries, shall be deemed to be a breach of this Section 5.4 by Ameritrade. For the avoidance of doubt, it is understood and agreed that participation by Ameritrade and its duly authorized directors, officers, employees, agents or Representatives in negotiations and discussions in compliance with the provisions of paragraph (a) of this Section 5.4 with respect to an Acquisition Proposal following the receipt thereof shall not be deemed to constitute the solicitation of an Acquisition Proposal if such initial receipt was not initiated, solicited, encouraged or facilitated in violation of this Section 5.4, and notwithstanding any changes to such Acquisition Proposal that may result from such discussions or negotiations.

          SECTION 5.5.   Legal Conditions .

          (b) Each party will notify the other promptly upon the receipt of: (i) any comments from any officials of any Governmental Authority in connection with any filings made pursuant hereto, and (ii) any request by any officials of any Governmental Authority for amendments or supplements to, or additional information regarding, any such filings.

          (b) During the Transition Period, Ameritrade shall, or shall cause its Subsidiaries to maintain a severance pay practice, program or arrangement for the benefit of each Affected Employee, including levels of severance and terms of severance, that is no less favorable than that provided by Waterhouse under such practice, program or arrangement in effect immediately prior to the Closing Date with respect to such Affected Employee, subject to Section 5.6(g) hereof. Notwithstanding the foregoing, in the event that, during the Transition Period:

               (i) Ameritrade determines that it will terminate any Affected Employee to whom TD has a written or legal obligation of repatriation to Canada, Ameritrade agrees to negotiate in good faith with TD regarding the impact of any such termination, provided , however , that (A) (1) Ameritrade shall not be obligated to pay any severance to such Affected Employee who accepts employment in Canada with TD and (2) Ameritrade shall pay one-half of the reasonable costs associated with such repatriation (intended to primarily represent relocation expenses) and (B) (1) Ameritrade shall be obligated to pay any severance to such Affected Employee who will not be employed in Canada with TD and (2) TD shall pay one hundred percent of the reasonable costs associated with such repatriation (intended to primarily represent relocation expenses); and

               (ii) Ameritrade terminates any Affected Employee during a quarterly or annual bonus period, Ameritrade agrees that, subject to Section 5.6(f), such Affected Employee shall be entitled to a pro rata bonus calculated by multiplying (A) the average of his or her bonus for the prior two quarterly or annual bonus periods (as applicable) times (B) a fraction, the numerator of which is the amount of days within the quarterly or annual bonus period, as applicable, that have elapsed prior to such Affected Employee’s date of termination, and the denominator of which is the total number of days in such bonus period.

          (c) Ameritrade shall, or shall cause its Subsidiaries to, give Affected Employees full credit for purposes of eligibility and vesting and benefit accrual (except for benefit accruals under any defined benefit pension plan) under such employee benefit plans or arrangements maintained by Ameritrade or its Subsidiaries in which such Affected Employees participate for such Affected Employees’ service with Waterhouse or its Business Subsidiaries (or its predecessors) to the same extent recognized by Waterhouse or the Business Subsidiaries immediately prior to the Closing Date. None of the provisions contained in this Section 5.6(c) shall operate to duplicate any benefit provided to any Affected Employee.

          (d) Ameritrade shall, or shall cause its Subsidiaries to, (i) waive all limitations with respect to the Affected Employees as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements under any welfare benefit plan maintained by Ameritrade after the Closing Date, to the extent such Affected Employees were not subject to such preexisting condition, exclusion and waiting period under the comparable Waterhouse Benefit Plan as of the time immediately preceding the Closing, and (ii) provide each

61

Affected Employee with credit for any co-payments and deductibles paid prior to the Closing Date in satisfying any applicable deductible or out-of-pocket requirements under any welfare plans that such Affected Employees are eligible to participate in after the Closing Date.

          (e) Ameritrade shall, or shall cause its Subsidiaries to, expressly assume or retain, all liabilities and obligations under or relating to the termination protection agreements set forth in Section 5.6(e) of the TD Disclosure Schedule and Ameritrade agrees to honor such termination protection agreements in accordance with their terms, subject to Section 5.6(g) hereof.

          (f) In respect of the quarterly and annual bonuses payable to Affected Employees for service rendered in TD’s fiscal years 2005 and 2006 (the “ Waterhouse 2005 and 2006 Bonus Program ”), Ameritrade shall, or shall cause its Subsidiaries to, consistent with this Section 5.6(f), continue to honor the terms and conditions of all obligations existing as of the Closing Date. Notwithstanding the foregoing, Ameritrade, or its Subsidiaries, shall only be responsible to pay its proportional share of any quarterly and annual bonuses under the Waterhouse 2005 and 2006 Bonus Program determined following the Closing Date, based on the ratio of the number of days elapsed in the quarterly or annual bonus period, as applicable, after the Closing Date, to the total number of days in such quarterly or annual bonus period, as applicable. TD shall retain responsibility to pay its proportional share of all such quarterly and annual bonuses under the Waterhouse 2005 and 2006 Bonus Program, based on the ratio of the number of days elapsed in the quarterly or annual bonus period, as applicable, prior to and including the Closing Date to the total number of days in such quarterly or annual bonus period, as applicable. Ameritrade and TD shall each pay their respective proportional share of any such bonuses according to Waterhouse’s methodology and timing, upon termination of the Affected Employee’s employment or on the regularly scheduled bonus payment date(s), as applicable. In accordance with the terms of the Waterhouse 2005 and 2006 Bonus Program, any Affected Employee who is terminated for unsatisfactory job performance or misconduct or who voluntarily resigns from employment, whether prior to, upon or following the Closing Date, shall not be eligible to receive payment of his or her quarterly and/or annual bonus, as applicable.

          (g) With respect to Affected Employees and former Waterhouse employees, TD will assume or retain all outstanding costs relating to equity under any TD or Waterhouse Benefit Plan, except for the unvested portion of restricted share unit awards as provided for in this Section 5.6(g). With respect to stock options, TD will retain and continue to expense the vested and currently unvested TD stock options and continue to administer such stock option plans at its expense. With respect to restricted share units (including performance restricted share units), TD will transfer the vested liability and offsetting hedge with respect to all such awards held by Affected Employees to Ameritrade at Closing, so that Ameritrade shall be responsible for the liability pertaining to the unvested portion of the outstanding awards to the extent provided in Section 5.6(g) of the TD Disclosure Schedule. TD will continue to administer the restricted share unit awards (including performance restricted share units) over the life of such awards at its expense. With respect to Waterhouse phantom stock options, (i) TD will assume the liability for payout in accordance with the terms of the relevant TD or Waterhouse Benefit Plan, and (ii) TD will continue to administer all such awards over the life of the awards and pay all associated costs for such administration.

62

          (h) As of the Closing Date, all Affected Employees shall be fully vested in their account balances in the Waterhouse 401(k) and Profit Sharing Plan (“ Waterhouse 401k Plan ”). In the event that the Waterhouse 401k Plan is merged into the Ameritrade 401(k) Profit Sharing Plan (“ Ameritrade 401k Plan ”), Affected Employees who had not yet satisfied the eligibility requirements for participation in the Waterhouse 401k Plan immediately prior to such merger shall be eligible to participate in the Ameritrade 401k Plan on the first plan entry date following the merger after they have satisfied the eligibility requirements for participation in the Ameritrade 401k Plan.

          (i) To the extent permissible under applicable law, Ameritrade shall take such actions as may be necessary to prevent the transactions contemplated under this Agreement from accelerating or increasing any amounts payable under, or otherwise providing any additional rights, any funding, or any additional benefits under, any Ameritrade Benefit Plan, and to the extent any employment agreement of an Ameritrade employee listed in Section 5.6(i) of the Ameritrade Disclosure Schedule would treat the transactions contemplated hereunder as a change of control, will use best efforts to negotiate and cause to be executed, to the fullest extent possible, individual amendments or waivers, as applicable, to such employment agreements prior to the Closing Date.

          (j) Prior to the Closing Date, Ameritrade, in consultation with TD, may enter into new or amended employment agreements with the individuals listed in Section 5.6(j) of the TD Disclosure Schedule. The new or amended employment agreements shall contain such terms and conditions which are negotiated in good faith between the applicable individual and Ameritrade (in consultation with TD) prior to the Closing Date.

          (k) TD shall not, and shall cause Waterhouse and the Business Subsidiaries not to, at any time within the ninety-day period prior to the Closing Date, effectuate a “plant closing” or “mass layoff” as those terms are defined in the Worker Adjustment and Retraining Notification Act of 1988, as amended (“ WARN ”), or any similar state or local statute, rule or regulation, affecting in whole or in part any site of employment, facility, operating unit or employee of Waterhouse or the Business Subsidiaries, without notifying Ameritrade in advance and without complying with the notice requirements and all other provisions of WARN and any similar state or local statute, rule or regulation. Ameritrade shall not, and shall cause its Subsidiaries not to, at any time beginning on the Closing Date and for a period of ninety calendar days thereafter, effectuate a “plant closing” or “mass layoff” as those terms are defined in WARN or any similar state or local statute, rule or regulation, with respect to the Affected Employees, without notifying TD in advance and without complying with the notice requirements and all other provisions of WARN and any similar state or local statute, rule or regulation.

          (l) Ameritrade, in consultation with TD, may establish a special integration bonus program for the benefit of Affected Employees who continue to be employed by Ameritrade or who are employed for a specified employment term by Ameritrade following the Closing Date.

          (m) Ameritrade may take such actions as it deems necessary to adjust all outstanding equity awards held by any Ameritrade employee or director in order to ensure that

63

all such equity awards maintain their intrinsic value, as determined prior to the payment of the Special Dividend, to account for the payment, if any, of any such Special Dividend.

          (n) Except as set forth in Section 5.6(n) of the TD Disclosure Schedule, TD shall retain liabilities and obligations relating to or arising with respect to any Benefit Plan of TD.

          (o) TD shall cause Waterhouse to terminate, immediately prior to the Closing, the Discretionary Severance Pay Plan of Waterhouse and Certain Affiliated Companies. Prior to the Closing, Ameritrade shall receive from TD evidence that such plan has been terminated in accordance with its terms.

TD shall retain all other obligations of any kind relating to or arising with respect to any Benefit Plan of TD or Waterhouse Benefit Plan which provides, or reflects or represents any liability to provide, retiree welfare benefit coverage to any Affected Employee, independent contractor or director for any reason, other than with respect to welfare benefit coverage provided in conjunction with severance during any period that severance is being paid and as required by COBRA. TD shall continue to administer all retiree welfare benefit plans at its expense.

          (q) Prior to the Closing Date, Ameritrade shall take all such actions which are necessary to adopt amendments to the Ameritrade health care Benefit Plans and TD shall take all such actions which are necessary to adopt amendments to the Waterhouse health care Benefit Plans to provide that the definition of employee eligible to receive benefits under such plans shall include any employee who has been terminated and is receiving payments under a severance arrangement sponsored either by Ameritrade or Waterhouse, as applicable.

          (r) No provision of this Section 5.6 shall create any third party beneficiary rights in any Affected Employee or in any current or former Waterhouse employee (including any beneficiary or dependent thereof) in respect to continued employment or resumed employment, and no provision of this Section 5.6 shall create any rights in any such persons in respect of any benefits that may be provided, directly or indirectly, under any employee benefit plan or arrangement.

64

          SECTION 5.8.   Financing and Other Actions for Special Dividend.   Promptly following the date of this Agreement, Ameritrade shall use all reasonable efforts to arrange for the Special Dividend Indebtedness pursuant to adequate and appropriate financing facilities and other debt funding sources to provide the cash necessary to pay that portion of the Special Dividend not funded by other Ameritrade available excess cash or the TD capital contribution contemplated by Section 5.23, in each case on terms reasonably acceptable to TD. Ameritrade shall use all reasonable efforts to (i) have such committed financing facilities and other debt funding sources available for drawdown by no later than the Closing Date, (ii) satisfy all conditions to such drawdown on a timely basis, and (iii) take all other corporate actions as may be necessary under applicable law to pay the Special Dividend.

          (b) Ameritrade shall give prompt notice to TD of any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate, or any failure of Ameritrade to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in each case, such that the conditions set forth in Section 6.3(a) or Section 6.3(b) would not be satisfied; provided , however , that any noncompliance with the foregoing shall not constitute the failure to be satisfied of a condition set forth in Article VI or give rise to any right of termination under Article VII unless the underlying breach shall independently constitute such a failure or give rise to such a right.

          SECTION 5.11.   Preparation of the SEC Proxy Statement . Promptly following the date of this Agreement (and to the extent reasonably possible in the circumstances, no later than 17 days after the delivery by TD to Ameritrade of the 2004 audited financial statements of Waterhouse contemplated by Section 5.19), Ameritrade shall prepare and file with the SEC the SEC Proxy Statement. TD shall furnish all information concerning TD and Waterhouse as may be reasonably requested in connection with any such action.

TD has engaged KPMG LLP to prepare a valuation of the Excluded Subsidiaries and the Other Assets (the “ Valuation Report ” ), and the Tax calculations contained in the Reorganization Report shall be based upon, and consistent with in all respects, the information contained in the Valuation Report. Upon final delivery of the Valuation Report to TD by KPMG LLP, and provided that Ameritrade has properly executed a release letter, in form and substance acceptable to KPMG LLP, TD shall provide Ameritrade with a copy of such report.

Ameritrade shall have the opportunity to review and consent to the Reorganization Report prior to completion of the Reorganization, which consent shall not be unreasonably withheld, conditioned or delayed.

          (c) Notwithstanding anything to the contrary contained in this Agreement, the provision for any Tax liability (including, without limitation, withholding and transfer Taxes)

67

associated with the Reorganization (the “ Reorganization Tax Liability ”), (i) as included in the calculation of Waterhouse’s Closing Date Net Tangible Book Value and (ii) as reflected on the Waterhouse Closing Date Balance Sheet and Waterhouse’s Final Statement, as the case may be, shall reflect the Reorganization Gain Amount, but in all other respects, the calculation of the Reorganization Tax Liability for these purposes shall be subject to the procedures set forth in Section 1.3.

          (b) Ameritrade shall prepare and file any Returns of Waterhouse and any of the Business Subsidiaries which are due after the Closing and such Returns shall (to the extent permitted by applicable law) be prepared and filed in a manner that is consistent with the prior practice of Waterhouse and any of the Business Subsidiaries, provided , however , that to the extent that any such Return includes an Excluded Subsidiary or is for a tax period (or portion thereof) ending on or before the Closing Date (the “ Pre-Closing Tax Period ”), TD shall prepare, subject to Ameritrade’s review and comment, and file such Return and such Return shall (to the extent permitted by applicable law) be prepared and filed in a manner that is consistent with the prior practice of Waterhouse and any of its Subsidiaries. TD shall pay when due all Waterhouse Pre-Closing Taxes with respect to Returns it files (except for any such Taxes that have been reflected or reserved for on Waterhouse’s Final Statement).

          (c) Unless reflected as an asset on Waterhouse’s Final Statement, the amount or economic benefit of any refunds, credits or offsets of Taxes of any of the Excluded Subsidiaries shall be for the account of TD and the amount or economic benefit of any refunds, credits or offsets of Taxes of Waterhouse and any of the Business Subsidiaries for any Pre-Closing Tax Period shall be for the account of TD. The amount or economic benefit of any other refunds, credits or offsets of Taxes of Waterhouse or any of the Business Subsidiaries shall be for the account of Ameritrade. Unless reflected as an asset on the Waterhouse Final Statement, the amount or economic benefit of any refunds, credits or offsets of Taxes of Waterhouse or any of the Business Subsidiaries for any period beginning before and ending after the Closing Date (a “ Straddle Period ”) shall be apportioned in accordance with the principles contained in Section 5.16(d) between TD and Ameritrade. Each party shall forward, and shall cause its Affiliates to forward, to the appropriate party the amount of any such refund, or the economic benefit of such

68

credit or offset to Tax, within (10) days after such refund is received or after such credit or offset is applied against another Tax liability, as the case may be.

          (d) In the case of any Straddle Period, the amount of Taxes allocable to the portion of the Straddle Period ending on the Closing Date shall be deemed to be: (i) in the case of Taxes imposed on a periodic basis (such as real or personal property Taxes), the amount of such Taxes for the entire period multiplied by a fraction, the numerator of which is the number of calendar days in the Straddle Period ending on and including the Closing Date and the denominator of which is the number of calendar days in the entire relevant Straddle Period and (ii) in the case of Taxes not described in clause (i) of this paragraph (such as franchise Taxes, Taxes that are based upon or related to income or receipts, based upon occupancy or imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible)), the amount of any such Taxes shall be determined as if such taxable period ended as of the close of business on the Closing Date.

          (e) If Ameritrade receives notice of an audit, claim, dispute or controversy relating to Taxes (a “ Tax Notice ”) which TD is required to pay pursuant to this Agreement, then Ameritrade shall notify TD in writing of such Tax Notice within twenty (20) days of receiving such notice; provided , however , that Ameritrade’s failure to provide such notice shall not release TD from any indemnification obligation hereunder unless TD’s ability to contest such Tax is materially adversely affected as a result of such failure to notify. TD shall have the right to control the conduct and resolution of any Tax contest; provided , however , that TD may decline to participate in such Tax contest. If TD controls the conduct of such Tax contest, TD regularly shall advise Ameritrade of the status of such Tax contest and shall not resolve such Tax contest without Ameritrade’s written consent, which consent shall not be unreasonably delayed, conditioned or withheld. If TD declines to control such Tax contest, then Ameritrade shall, at TD’s expense, have the right to control the conduct of such Tax contest; provided , however , that Ameritrade shall regularly advise TD of the status of such Tax contest and shall not resolve such Tax contest without TD’s written consent, which consent shall not be unreasonably delayed, conditioned or withheld. In the event of a dispute between TD and Ameritrade regarding the conduct or resolution of any Tax contest, such dispute shall be referred to a nationally recognized accounting or law firm mutually acceptable to TD and Ameritrade (the “ Tax Arbitrator ”). The decision of the Tax Arbitrator shall be final and binding, and its fees and costs shall be shared equally by the disputing parties. Each party shall bear its own costs for participating in such dispute resolution.

All other Transfer Taxes incurred in connection with this Agreement and the transactions contemplated hereby shall be paid 50% by TD and 50% by Ameritrade. Notwithstanding anything to the contrary in this Section 5.16(f), TD shall not be responsible for any payment with respect to Transfer Taxes if and to the extent an amount has been reflected, accrued or reserved for on Waterhouse’s Final Statement in respect of such Transfer Taxes. TD and Ameritrade shall cooperate in timely making all filings, Returns, reports and forms as may be required to comply

69

with the provisions of such tax laws. For purposes of this Agreement, “ Transfer Taxes ” shall mean transfer, documentary, sales, use, registration and other such taxes (including all applicable real estate transfer taxes).

          (g) TD shall cause the provisions of any agreement, arrangement or practice with respect to Taxes (including any Tax sharing agreements) between TD or any of its Subsidiaries which are not Business Subsidiaries, on the one hand, and Waterhouse or any of the Business Subsidiaries, on the other hand, or between Waterhouse and any of the Business Subsidiaries, to be terminated at Closing.

TD will, and will cause its Subsidiaries and its and their respective Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than Ameritrade with respect to any TD Acquisition Proposal. For the avoidance of doubt, nothing in this Section 5.18 shall apply to the Reorganization.

          SECTION 5.19.   Waterhouse 2004 Audited Financials . TD shall use all reasonable efforts to cause to be prepared and delivered to Ameritrade, as promptly as practicable after the date hereof and in no event later than the 60 ^th day following the date of this Agreement, the audited consolidated balance sheet, statement of income, statement of retained earnings and statement of cash flows for Waterhouse as of October 31, 2004.

          SECTION 5.20.   Outsourcing Agreement; Website Matters . (a) TD and Ameritrade agree to commence good faith negotiations, promptly following the date of this Agreement, regarding the terms of a formal outsourcing arrangement to be entered into by TD Waterhouse Investor Services, Inc. and TD Waterhouse Bank, N.A. pursuant to which, as of the Closing Date, or commencing on such later date as the parties may mutually agree, TD Waterhouse Investor Services, Inc. shall agree to outsource, and TD Waterhouse Bank, N.A. shall agree to perform, the various banking services currently provided under the Services Agreement, dated as of April 22, 2002, between TD Waterhouse Bank, N.A. and Waterhouse (such services, the “ Banking Services ” and such agreement, the “ Original Services Agreement ”).

          SECTION 8.4.   Indemnification Procedures .

          (a) If an Indemnified Ameritrade Entity or an Indemnified TD Entity (each, an “ Indemnified Entity ”) believes that a claim, demand or other circumstance exists that has given or may reasonably be expected to give rise to a right of indemnification under this Article VIII (whether or not the amount of Damages relating thereto is then quantifiable), such Indemnified Entity shall assert its claim for indemnification by giving written notice thereof (a “ Claim Notice ”) to the party from which indemnification is sought (the “ Indemnifying Party ”) (i) if the event or occurrence giving rise to such claim for indemnification is, or relates to, a claim, suit, action or proceeding brought by a Person not a party to this Agreement or affiliated with any such party (a “ Third Party ”), within ten Business Days following receipt of notice of such claim, suit, action or proceeding by such Indemnified Entity, or (ii) if the event or occurrence giving rise to such claim for indemnification is not, or does not relate to, a claim, suit, action or proceeding brought by a Third Party, within 30 days after the discovery by the Indemnified Entity of the circumstances giving rise to such claim for indemnity. Each Claim Notice shall describe the claim in reasonable detail, including the amount of the Damages relating thereto (if quantifiable), the event or occurrence giving rise thereto and the basis for such claim for indemnification.

          (b) If any claim or demand by an Indemnified Entity under this Article VIII relates to an action or claim filed or made against an Indemnified Entity by a Third Party, the Indemnifying Party may elect at any time to negotiate a settlement or a compromise of such action or claim or to defend such action or claim, in each case at its sole cost and expense (subject to the last sentence of this Section 8.4(b)) and with its own counsel. If, within 30 days of receipt from an Indemnified Entity of any Claim Notice with respect to a Third Party action or claim, the Indemnifying Party (i) advises such Indemnified Entity in writing that the Indemnifying Party will not elect to defend, settle or compromise such action or claim or (ii) fails to make such an election in writing, such Indemnified Entity may (subject to the Indemnifying Party’s continuing right of election in the preceding sentence), at its option, defend, settle or otherwise compromise or pay such action or claim; provided that any such settlement or

82

compromise shall be permitted hereunder only with the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, delayed or conditioned. Unless and until the Indemnifying Party makes an election in accordance with this Section 8.4(b) to defend, settle or compromise such action, all of the Indemnified Entity’s reasonable costs and expenses arising out of the defense, settlement or compromise of any such action or claim shall be Damages subject to indemnification hereunder to the extent provided herein. Each Indemnified Entity shall make available to the Indemnifying Party all information reasonably available to such Indemnified Entity relating to such action or claim. In addition, the parties shall render to each other such assistance as may reasonably be requested in order to ensure the proper and adequate defense of any such action or claim. The party in charge of the defense shall keep the other parties fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. If the Indemnifying Party elects to defend any such action or claim, then the Indemnified Entity shall be entitled to participate in such defense with counsel, at such Indemnified Entity’s sole cost and expense (unless there is, under applicable standards of professional conduct, a conflict between the positions of the Indemnifying Party and the Indemnified Entity that would preclude or render inadvisable joint representation of such parties, in which case the Indemnifying Party shall be liable for the fees and expenses hereunder with respect to one law firm, in addition to local counsel in each applicable jurisdiction, to represent the Indemnified Entity). In the event the Indemnifying Party assumes the defense of (or otherwise elects to negotiate or settle or compromise) any action or claim as described above, the Indemnified Entity shall reimburse the Indemnifying Party for all costs and expenses incurred by the Indemnifying Party in connection with such defense (or negotiation, settlement or compromise) to the extent that such costs and expenses do not exceed the amount of the remaining Threshold (with any such costs and expenses being counted toward the Threshold). In each case in which the Indemnifying Party has elected to assume the defense of any action or claim pursuant to this Section 8.4(b), the Indemnifying Party may not settle or compromise such action or claim without the consent of the Indemnified Entities, which consent shall not be unreasonably withheld, delayed or conditioned; provided , however , that under no circumstances will an Indemnified Entity be required to consent to any settlement or compromise (i) that does not include as a term thereof the release by the plaintiff or claimant of the Indemnified Entity from all liability with respect to such claim or action, other than amounts paid by the Indemnifying Party; or (ii) that imposes on the Indemnified Entity any equitable remedies or other non-monetary relief that could affect the Indemnified Entity’s business or operations.

          (c) In the event of any conflict between this Section 8.4 and Section 5.16 with respect to claims relating to Taxes, Section 5.16 shall govern.

          SECTION 8.5.   General .

          (a) Each Indemnified Entity shall be obligated in connection with any claim for indemnification under this Article VIII to use all commercially reasonable efforts to obtain any insurance proceeds available to such Indemnified Entity with regard to the applicable claims and to recover any amounts to which it may be entitled in respect of the applicable claims pursuant to contractual or other indemnification rights that any of the Indemnified Parties may have against Third Parties. The amount which the Indemnifying Party is or may be required to pay to any Indemnified Entity pursuant to this Article VIII shall be reduced (retroactively, if necessary) by any insurance proceeds, tax benefits actually realized or other amounts actually

83

recovered by or on behalf of such Indemnified Entity in reduction of the related Damages. If an Indemnified Entity shall have received the payment required by this Agreement from the Indemnifying Party in respect of Damages and shall subsequently receive insurance proceeds, tax benefits or other amounts in respect of such Damages, then such Indemnified Entity shall promptly repay to the Indemnifying Party a sum equal to the amount of such insurance proceeds, tax benefits actually realized or other amounts actually received.

          (b) In addition to the requirements of Section 8.5(a), each Indemnified Entity shall be obligated in connection with any claim for indemnification under this Article VIII to use all commercially reasonable efforts to mitigate Damages upon and after becoming aware of any event which could reasonably be expected to give rise to such Damages.

          (c) The Indemnifying Party shall be subrogated to any right of action which the Indemnified Entity may have against any other Person with respect to any matter giving rise to a claim for indemnification hereunder.

          (d) The indemnification provided in this Article VIII shall be the exclusive post-Closing remedy available to any party hereto with respect to any breach of any representation, warranty, covenant or agreement in this Agreement, or otherwise in respect of the transactions contemplated by this Agreement, except as otherwise expressly provided in this Agreement; provided , however , that this Section 8.5(d) shall not apply or limit the remedy available to either party hereto with respect to any fraudulent act or willful breach of any representation, warranty, covenant or agreement in this Agreement by the other party hereto.

          (e) The parties agree that any indemnification payment made pursuant to this Agreement shall be treated as an adjustment to the Exchange Consideration, unless otherwise required by applicable law.

          (f) All indemnity payments under this Agreement shall be payable in United States dollars. If any indemnification claims are incurred in a currency other than United States dollars, then such amount denominated in such foreign currency shall be converted into an amount denominated in United States dollars using the noon buying rate for such foreign currency as certified by the New York Federal Reserve Bank on the Business Day immediately preceding the date on which such payment is paid.

          (g) All claims for indemnification made by any party under this Agreement shall be without duplication of any corresponding claim for indemnification made by such party under the Ameritrade Canada Purchase Agreement, and vice versa .
