The purchaser at any such sale shall not assume, nor shall his or its heirs, legal representatives, successors or assigns, be deemed to have assumed, by reason of the acquisition of property or rights mortgaged hereunder, any liability or obligation of any lessee or operator of the Mortgaged Property, or any part thereof, arising by reason of any occurrence taking place prior to such sale.

In the same events as first above stated, and in the same manner, successive substitute trustees may thereafter be appointed.

F. Statements by Trustee.

I. Remedies Cumulative and Non-Exclusive. The rights of entry, sale, or suit, as hereinabove or hereinafter conferred, are cumulative of all other rights and remedies herein or by law or in equity provided, and shall not be deemed to deprive the holder of the Indebtedness or Trustee of any such other legal or equitable rights or remedies, by judicial proceedings or otherwise, appropriate to enforce the conditions, covenants and terms of this Deed of Trust and of any note or guaranty reflecting the Indebtedness, and the employment of any remedy hereunder, or otherwise, shall not prevent the concurrent or subsequent employment of any other appropriate remedy or remedies.

DEED OF TRUST — Page 10

immediately declared due and payable, at the option of Mortgagee and without demand, presentment or other notice (including, but not limited to notice of intention to accelerate maturity and notice of acceleration of maturity), and the Mortgaged Property shall become subject to the foreclosure proceedings and power of sale hereunder.

C. Application of Proceeds.

After such application has been so made by Mortgagee, the balance of any such payment or payments remaining shall be paid to Mortgagor.

D. No Postponement of Installments on Indebtedness.
