1. DEFINITIONS AND INTERPRETATION

The master definitions and construction agreement made between, inter alia, the parties to this Agreement on September 30, 2013 (as the same may be amended, restated and/or supplemented from time to time, the “Master Definitions and Construction Agreement”) is expressly and specifically incorporated into this Agreement and, accordingly, the expressions defined in the Master Definitions and Construction Agreement (as so amended, restated and/or supplemented) shall, except where the context otherwise requires and save where otherwise defined herein, have the same meanings in this Agreement, including the recitals hereto and this Agreement shall be construed in accordance with the interpretation provisions set out in Section 2 of the Master Definitions and Construction Agreement. For the purposes of this Agreement, this Agreement has the same meaning as Guaranteed Deposit Account Contract in the Master Definitions and Construction Agreement.

2. THE GDA ACCOUNT

The GDA Provider confirms that (on the instructions of the Guarantor) the GDA Account has been opened in its books in the name of the Guarantor, and it agrees to accept on deposit in the GDA Account all monies transferred, from time to time, to the GDA Account, subject to and upon the terms of this Agreement, the Bank Account Agreement, the Cash Management Agreement, the Security Agreement and the Guarantor Agreement.

3. INTEREST

3.1 Interest shall accrue daily on the GDA Balance and shall be paid monthly in arrears on the 10^th Canadian Business Day of the following month at a rate of interest equal to the GDA Rate (calculated on the basis of the actual number of days elapsed and a 365 day year) by payment for value on the same day to the GDA Account or such other accounts as the Guarantor shall specify.

1

3.2 On any day on which interest is payable by the GDA Provider under this Agreement, the GDA Provider shall pay the amount of interest then due in immediately available, freely transferable, cleared funds by no later than the close of business (Eastern Standard Time) on that day (or if such day is not a Canadian Business Day, the next succeeding Canadian Business Day).

3.3 In the event that a Guarantor Acceleration Notice is served on the Guarantor, then, on the date of such Guarantor Acceleration Notice, the GDA Provider shall pay to the Bond Trustee the aggregate of all interest accrued on the GDA Account on each day during the month in which such Guarantor Acceleration Notice is served up to (but excluding) the date of such Guarantor Acceleration Notice.

4.2 The Guarantor may deposit, or procure the deposit of, sums in the GDA Account, to the extent permitted by the terms of the Cash Management Agreement, the Bank Account Agreement, the Security Agreement and the Guarantor Agreement, and the GDA Provider agrees to accept and credit to the GDA Account such sums in accordance with the terms hereof.

5.2 The Guarantor (or the Cash Manager or the Bond Trustee on its behalf) may (with the prior written consent of the Bond Trustee, which consent shall not be withheld unless the Bond Trustee determines that the termination of this Agreement would be materially prejudicial to the interests of the Covered Bondholders) terminate this Agreement in the event that default is made by the GDA Provider in the performance or observance of its covenants and obligations, or a breach by the GDA Provider is made of any of its representations and warranties, respectively, under Sections 6.1(c), 6.1(d), 6.1(e), 6.1(g) and 6.1(h).

5.3 The Guarantor will (or will cause the Cash Manager to) terminate this Agreement if an Issuer Event of Default occurs and is continuing (provided that the GDA Provider is the Issuer or an Affiliate thereof).

14.2 Each proposed amendment, variation or waiver of rights under this Agreement that is considered by the Guarantor to be a material amendment, variation or waiver, shall be subject to satisfaction of the Rating Agency Condition. For certainty, any amendment to (i) a Ratings Trigger provided for in this Agreement that lowers the ratings specified therein, or (ii) the consequences of breaching a Ratings Trigger provided for in this Agreement that makes such consequences less onerous, shall be deemed to be a material amendment. The Guarantor shall deliver notice to the Rating Agencies from time to time of any amendment, variations or waivers in respect of which satisfaction of the Rating Agency Condition is not required, provided that failure to deliver such notice shall not constitute a breach of the obligations of the Guarantor under this Agreement.

14.3 The Guarantor (or the Cash Manager on its behalf) will deliver notice to CMHC from time to time of any amendment, restatement or waiver with respect to which notice to CMHC is required by the CMHC Guide, provided that failure to deliver such notice will not constitute a breach of the obligations of the Guarantor under this Agreement.
