Dear Xx. Xxxxxxxxxx:

As you know the Implementation Agreement between Xxxxxxxx Consulting LLP and The
Northern Trust dated September 30, 1991 expired on December 31, 1995. The 
purpose of this letter is to document our mutual consent to extend that 
Implementation Agreement for 90 days, through March 31, 1996, in order to allow 
us ample time to develop a mutually agreeable Agreement for our work going 
forward.

Thank you for the continued opportunity to assist The Northern Trust with this 
important project. If you have any questions about this letter please do not 
hesitate to contact me at (000) 000-0000.



Sincerely,
 

Xxxx X. Xxxxx
