ARTICLE I

CERTAIN AMENDMENTS

1.01 Base Indenture. Pursuant to Section 9.02 of the Base Indenture, the Company and the Trustee (in the case of the Trustee, acting in reliance upon the evidence of the Requisite Consent the Company has received from the Holders of the outstanding Securities, as certified by Global Bondholder Services Corporation) hereby agree to amend or supplement certain provisions of the Base Indenture as follows:

(a) At such time the Other Remaining Notes are no longer outstanding and the Notes are the only outstanding series of Securities under the Base Indenture (“Termination of the Other Remaining Notes”), the following amendments shall enter into effect:

“Section 4.07. Reports by Company.

The Company shall comply with the provisions of Section 314(a) of the Trust Indenture Act to the extent applicable.”

“Section 5.01. Consolidation, Merger by the Company. The Company shall not consolidate with or merge into any other Person and the Company shall not permit any Person to consolidate with or merge into the Company, unless:

This Section 5.01 will not apply to:

Section 5.02. Successor Corporation Substituted. Upon any consolidation or merger, in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof, the successor Person formed by such consolidation or into or with which the Company is merged shall succeed to, and be substituted for (so that from and after the date of such consolidation or merger, the provisions of this Indenture referring to the “Company” shall refer instead to the successor Person and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein.

Such successor Person may cause to be signed, and may issue either in its own name or in the name of the Company prior to such succession, any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor Person instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities which previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication pursuant to such provisions and any Securities which such successor Person thereafter shall cause to be signed and delivered to the Trustee on its behalf for that purpose pursuant to such provisions. All of the Securities so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof.

In case of any such consolidation, merger, such changes in phraseology and form may be made in the Securities thereafter to be issued as may be appropriate.

indebtedness for borrowed money secured by a pledge, lien or other encumbrance, except for Permitted Liens, on the Voting Stock of TD Ameritrade Online Holdings Corp., TD Ameritrade Clearing, Inc. and TD Ameritrade, Inc. unless the Company shall cause the Floating Rate Notes to be secured equally and ratably with (or, at the Company’s option, prior to) any indebtedness secured thereby.

(b) When a Lien securing indebtedness for borrowed money that gave rise to the requirement under Section 4.01(a) that the Floating Rate Notes be secured equally and ratably thereby is released or terminated, as the case may be, by the holder or holders thereof, then the corresponding Lien that secures the Floating Rate Notes shall be deemed automatically released or terminated, as the case may be, without further act or deed on the part of any Person. At the request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release or termination.”
