other Transaction Agreement which are defined by reference to the Framework Agreement or the Master Repurchase Agreement, and (iii) this sentence shall be effective to amend each of the relevant Transaction Agreements (including the Master
Repurchase Agreement and each Annex thereto) to the extent necessary to give effect to the foregoing clauses (i) and (ii). 

4.3 Guarantor Acknowledgment and Consent. The Guarantor hereby acknowledges the Parties’ entry into this Amendment and consents to
