Voting Instruction Form ("VIF") - Annual General Meeting to be held on June 17, 2025

This VIF is solicited by and on behalf of Telesat Corporation.

Notes to VIF

The undersigned holder(s) (the "holder") of Class C exchangeable limited partnership units ("Partnership exchangeable units") of Telesat Partnership LP ("Partnership") is entitled to instruct Telesat Corporation as general partner of the Partnership (the "General Partner") to provide instructions to TSX Trust Company (as trustee of Telesat Corporation Trust) as to the exercise of the votes comprised in the voting rights attached to the Class C Special Voting Share of Telesat (the "Special Voting Share") for each Partnership exchangeable unit owned of record by the holder on the record date of April 24, 2025 (the "Beneficiary Votes") at the Meeting as follows:

1. for the Trustee to cast and exercise the Beneficiary Votes as indicated below; OR
2. give a proxy to designated agent or representative of Management of Telesat (a "Management nominee") to exercise, as proxy of the Trustee, the Beneficiary Votes as indicated below.

Should a holder of Partnership exchangeable units want to exercise personally the Beneficiary Votes with respect to the Special Voting Share, such holder must provide instructions to the General Partner by no later than June 11, 2025, and the General Partner will instruct the Trustee to sign and deliver to such holder (or its designee) a proxy to the holder (or its designee) permitting the holder or such designee to attend the Meeting and exercise personally, as proxy of the Trustee, the Beneficiary Votes.

Unless the holder validly instructs the General Partner to instruct the Trustee to give a proxy in the manner provided herein under "Appointment of Proxyholder", the holder will be deemed to have instructed and directed the General Partner to further instruct the Trustee to cast and exercise the Beneficiary Votes as indicated below.
