                  Amendment dated as of September 1, 1998 to the Consulting
Agreement (the "Consulting Agreement") dated as of August 9, 1996 between

                              W I T N E S S E T H:

                  WHEREAS, the Consulting Agreement effected certain changes to
the Agreement dated as of December 23, 1988 between Assaf and the Corporation
(the "Change in Control Agreement"); and

                  WHEREAS, the Corporation recently updated its change in
control agreements generally and Assaf's Change in Control Agreement in
particular; and

                  WHEREAS, the parties hereto wish to make conforming changes to
the Consulting Agreement;

                  NOW, THEREFORE, in consideration of the premises and of the
mutual covenants herein contained, the parties hereto hereby amend the
Consulting Agreement as follows:

                  Effective as of the date hereof (the "Amendment Date"), the
         provisions of Section 8(a) of the Consulting Agreement (as originally
         set forth in the Consulting Agreement, the "Consulting Agreement Change
         of Control Provisions") have been given effect in the amended and
         restated Change of Control Agreement. Accordingly, the Consulting
         Agreement Change of Control Provisions shall be without further force
         or effect, except that it is still the understanding of the parties
         that the provisions of Section 3 of the Consulting Agreement shall be
         applicable in the event of a Change in Control, that the Change in
         Control Agreement may be amended by mutual agreement of Assaf and the
         Corporation, and that any such amendments shall be given effect for all
         purposes of the Consulting Agreement.

                  References in the Consulting Agreement to the Change in
         Control Agreement (other than in the Consulting Agreement Change of
         Control Provisions) shall be deemed to refer to the Change in Control
         Agreement as amended and restated as of the Amendment Date, as the same
         may be further amended in accordance with the preceding paragraph.

Subject to the amendments set forth above, the Consulting Agreement shall remain
in full force and effect.
