Dear Xx. Xxxxxx & Xx. Xxxxx:

We are  writing  with  respect  to  your  management  agreement  concerning  the

would like to extend the term of the Management  Agreement through June 30, 1999

paid annually  instead of  quarterly.  All other  provisions  of the  Management
Agreement will remain unchanged.

Please indicate your agreement to and acceptance of this modification by signing
one copy of this letter and returning it to the attention of Xx. Xxxxxx Xxxxxxxx
at the address above or fax to 000-000-0000.  If you have any questions I can be

Very truly yours,
