Pursuant to its efforts to sell such REO Property, the Servicer shall either itself or through an agent selected by the Servicer protect and conserve such REO Property in the same manner and to such extent as is customary in the locality where such REO Property is located and may, incident to its conservation and protection of the interests of the Purchaser, or its designee, rent the same, or any part thereof, as the Servicer deems to be in the best interest of the Purchaser, or its designee, for the period prior to the sale of such REO Property.

In the event that the Purchaser, or its designee, acquires any Mortgaged Property as aforesaid or otherwise in connection with a default or imminent default on a Mortgage Loan, the Servicer shall dispose of such Mortgaged Property as soon as practicable in a manner that maximizes the Liquidation Proceeds thereof, but in no event later than three years after its acquisition by the Purchaser, or its designee. In that event, the Purchaser, or its designee, shall have been supplied with an Opinion of Counsel to the effect that the holding by the Purchaser, or its designee, of such Mortgaged Property subsequent to a three-year period, if applicable, will not result in the imposition of taxes on “prohibited transactions” of any REMIC as defined in section 860F of the Code or cause any REMIC to fail to qualify as a REMIC at any time, the Purchaser, or its designee, may continue to hold such Mortgaged Property (subject to any conditions contained in such Opinion of Counsel) after the expiration of such three-year period. Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Purchaser, or its designee, shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Purchaser, or its designee, in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as “foreclosure property” within the meaning of section 860G(a)(8) of the Code or (ii) subject any REMIC to the imposition

of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless the Servicer has agreed to indemnify and hold harmless the Purchaser, or its designee, with respect to the imposition of any such taxes.”
