    Dear
Gentlemen:

     

    Atlanta
Gas Light Company (“AGLC”)  hereby proposes to extend the Term of the 2005
 Modified Agreement.   The 2005 Modified Agreement
 modififed the Term of  Services associated with the operation,
monitoring, and maintenance of groundwater to terminate as of June 30,
2005.  This Term Extension changes the termination date for such Services
from June 30, 2005 to August 31, 2005. 

     

    I. Section 1 Term is
hereby amended by deleting June 30, 2005 and replacing it with August 31,
2005.   The last provision in Section 1 now reads:

     

    “Notwithstanding
the above termination date, all work to be performed by Retec under the 2005
Modified Agreement for the Sites listed on Amended Exhibit 2 of the Amended
Agreement that is associated with or in connection to groundwater monitoring,
groundwater analysis, groundwater treatment systems, groundwater collection
systems, including all Administrative and General, and Technical, as those terms
are used in Amended Exhibit A of the 2005 Modified Agreement, which is identical
to Exhibit A of the Amended Agreement, shall terminate on August 31,
2005.”

     

    Except as
otherwise provided herein, all defined terms shall have the meanings provided in
the Amended Agreement.  Except as modified herein, all terms, conditions,
responsibilities, and obligations of the Parties set forth in the Amended
Agreement shall remain in full force and effect. 

     

    


     

    


    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    


     

    If you
are in agreement with the proposed Term Extension set forth above, please so
signify by signing on behalf of Retec in the space provided below.  If you
are in agreement, the effective date of the modifications will be August 1,
2005

     

                                                                                       
Sincerely,
