Ladies and Gentlemen:

Reference is made to the Amended and Restated Sales Agreement, dated as of December 6, 2024 (the “Sales Agreement”), by and among Sprott Physical Platinum and Palladium Trust, a trust formed and organized under the laws of the Province of Ontario (the “Trust”), Sprott Asset Management LP, a limited partnership organized under the laws of the Province of Ontario (the “Manager”), and Cantor Fitzgerald & Co., Cantor Fitzgerald Canada Corporation, Virtu Americas LLC, Virtu Canada Corp., Canaccord Genuity Corp., Canaccord Genuity LLC, BMO Nesbitt Burns Inc. and BMO Capital Markets Corp. (collectively, the “Agents”), pursuant to which the Trust may, from time to time, issue and sell through the Agents units of the Trust.

In connection with the foregoing, the parties hereto wish to amend the Sales Agreement through this Amendment No. 1 to the Sales Agreement (this “Amendment”) to make certain changes to the Sales Agreement with effect on and after the date hereof. Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Sales Agreement.

SECTION 1. Amendments to the Sales Agreement. The parties hereto agree, from and after the date hereof, that:

(a)                   The third paragraph of Section 1 is hereby deleted and replaced in its entirety with the following:

“The Trust has filed with the Commission a registration statement on Form F-10 (File No. 333-281996) relating to the Shelf Securities and an appointment of agent for service of process on Form F-X (a “Trust Form F-X”) relating to the registration statement, and the Trust has caused RBC Investor Services Trust to file with the Commission an appointment of agent for service of process on Form F-X (a “Trustee Form F-X”). The Trust may file one or more additional registration statements from time to time that will contain a Base Prospectus (as defined below) and related prospectus, if applicable (which shall be a Prospectus (as defined below)), with respect to the Placement Units. The registration statement on Form F- 10, or any subsequent registration statement on Form F-10, as most recently amended and including the information (if any) deemed to be a part of such registration statement at the time of effectiveness pursuant to Form F-10 under the U.S. Securities Act of 1933, as amended (the “Securities Act”), is hereinafter called the “Registration Statement”; the base prospectus relating to the Shelf Securities filed as part of the Registration Statement, in the form in which it has been filed with the Commission, is hereinafter called the “Base Prospectus”. For purposes of this Agreement, “Prospectus” means the final prospectus supplement relating to the offering of the Placement Units, together with the Base Prospectus, filed with the Commission pursuant to General Instruction II.L. of Form F-10 in accordance with Section 8(w) hereof. As used herein, the terms “Registration Statement”, “Base Prospectus” and “Prospectus” shall include the documents, if any, incorporated by reference therein as of the relevant time.”

SECTION 2. No Other Amendments; References to Agreements. Except as set forth in this Amendment, all other terms and provisions of the Sales Agreement shall continue in full force and effect. All references to the Sales Agreement in the Sales Agreement or in any other document executed or delivered in connection therewith shall, from the date hereof, be deemed a reference to the Sales Agreement as amended by this Amendment. Notwithstanding anything to the contrary contained herein, this Amendment shall not have any effect on the terms of the Sales Agreement prior to date of this Amendment, and the rights and obligations of the parties thereunder, including, without limitation, the representations, warranties and agreements (including the indemnification and contribution provisions) contained in the Sales Agreement.

SECTION 3. Governing Law. This Amendment shall be governed by, and construed in accordance with, the internal laws of the State of New York without regard to the principles of conflicts of laws.

SECTION 4. Headings. The headings herein are included for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Amendment or the Sales Agreement.

SECTION 5. Counterparts. This Amendment may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery of the executed Amendment by one party to the other may be made by facsimile or electronic transmission of a portable document format (PDF) file (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com).
