The Mortgagor hereby agrees to pay any and all ad valorem taxes and special assessments of each and every nature against the Property, in a timely manner, and the Mortgagor covenants and agrees to and for the benefit of the Mortgagee that such taxes and assessments shall never become delinquent. In the event any such taxes shall be or remain unpaid for a period of thirty (30) days after payment thereof is due, the Mortgagee shall have the right, but not the obligation, to pay such taxes or assessments, and all interest and penalties then due thereon, and collect the same from the Mortgagor, with interest accruing thereto at the rate of ten percent (10%) per annum.

Such insurance proceeds or any part thereof received by the Mortgagee may, at the Mortgagee’s option, be applied upon the indebtedness secured hereby in such manner as the Mortgagee may elect, or be applied in restoring, rebuilding or repairing the property damaged, or be released to the Mortgagor. In the event of the foreclosure of this Mortgage or upon transfer of title to the Property in extinguishment of the indebtedness secured hereby, all right, title and interest of the Mortgagor in and to any insurance policies then in force will pass to the purchaser or grantee. This Mortgage further secures the obligation of the Mortgagor pursuant to such covenants and agreements.

E. Title and Priority of Mortgage. The Mortgagor further represents, warrants, covenants and agrees with the Mortgagee that this Mortgage is prior and superior to all other liens and encumbrances of every nature and kind whatsoever except taxes and assessments not yet due and easements and rights of way of record as of the date hereof. The Mortgagor will defend the title to the Property and the priority and validity of the lien of this Mortgage against all claims or demands whatsoever and will promptly pay and discharge any and all claims or liens which may subsequently be asserted against any portion of the Property which is then subject to the lien of this Mortgage. This Mortgage further secures such covenant and warranty of title and priority of this Mortgage.

F. Costs and Expenses. The Mortgagor further covenants and agrees that in the event that proceedings are initiated to foreclose this Mortgage, either judicially or by exercise of the power of sale, or if the Mortgagee or any holder hereof is compelled to defend the lien of this Mortgage or otherwise to enforce or protect the rights and interests of the Mortgagee or other holder hereunder, the Mortgagor will pay to the Mortgagee a reasonable attorneys’ fee and all costs or expenses incurred therein, including court costs, abstracting charges, insurance premiums and taxes, which this Mortgage also secures, and if judgment be entered for any purpose the judgment shall include an award in favor of the Mortgagee or other holder hereof for such fees, costs and expenses.
