3.

7. All terms used in this Indemnity which appear in boldface type and are not defined herein, shall have the meaning ascribed to such term or terms in the Security Deed.

8. Whenever reference is made to the payment of “attorneys’ fees,” “reasonable attorneys’ fees” or words of similar import in this Indemnity, the same shall mean and refer to the payment of actual attorneys’ fees incurred based upon the attorney’s normal hourly rate and the number of hours worked, and not the statutory attorneys’ fees defined in O.C.G.A. Section 13-1-11.
