        If either (A) Party B has during any

        any calendar quarter,

        (a)        
        any Loan shall be sold from the Portfolio (other than a Loan repurchased by the Seller as a result of a breach of representation
        or warranty made with respect to such Loan in the Mortgage Sale Agreement);

        (b)         
        any Loan shall be acquired by Party B and included in the Portfolio; or

        (c)         
        the interest rate applicable to any Variable Rate Loan shall be adjusted in accordance with the Servicing Agreement,

	 	(each, a “Portfolio Adjustment”), then Party B (or the Servicer on behalf of Party B) shall notify Party A (which notice shall include sufficient information for Party A to make the determinations required by this section) and Party A shall, on or before the first Payment Date following such Guarantor Calculation Period or calendar quarter, as applicable, determine the amount by which the Party A Spread (such revised Party A Spread, the “Adjusted Spread”) shall be adjusted as a result of such Portfolio Adjustment; provided, however, that at no time shall the Adjusted Spread be insufficient to ensure that Party B has sufficient funds to (i) make any payments of interest due on the Intercompany Loan or following a Covered Bond Guarantee Activation Event, all non-termination payments when due under all Covered Bond Swaps then outstanding and all payments (other than payments of principal) when due in respect of any Covered Bonds for which no Covered Bond Swap has been entered into, or (ii) pay any other Guarantor expenses then due and (iii) retain 35 bps of additional spread.
	 	With effect from and including such Payment Date, the Party A Spread shall be the related Adjusted Spread.

	Additional Termination Event:	It shall be an Additional Termination Event, with respect to which Party B shall be the sole Affected Party and all Transactions shall be Affected Transactions, if a Portfolio Adjustment is undertaken notwithstanding the fact that the Adjusted Spread would be insufficient to satisfy the test described above under Spread Determination Procedure.
	Partial Termination:	If at any time a portion of the Portfolio is sold, a Partial Termination Payment will be due from Party B to Party A or from Party A to Party B, as applicable. Such Partial Termination Payment will be zero if agreed by both Party A and Party B.
	Partial Termination Payment:	The Partial Termination Payment is equal to the net present value of the projected cash flows under this Agreement associated with the portion of the Portfolio that is being sold. The net present value will be calculated using interest rates derived from the then current Canadian dollar swap market and assuming that Party B is the sole Affected Party. The projected cash flows will be determined in a commercially reasonable manner by Party A. The Partial Termination Payment will be determined by Party A as soon as practicable after Party B notifies Party A of the specific details of the sale. Party B is obligated to provide Party A with 5 Business Days notice of any planned sale of all or part of the Portfolio.
