         WHEREAS,  this  Assignment and Assumption  Agreement (the  "Agreement")
relates to the  364-Day  Credit  Agreement  dated as of June 11,  1999 among the
Company, the Borrower named therein, the Assignors, as Banks, and the Agent (the
"Credit Agreement");

         WHEREAS, as provided under the Credit Agreement, each Assignor has a
Commitment to make Loans to the Borrower;

         WHEREAS, there are no Loans outstanding under the Credit Agreement at
the date hereof; and

         WHEREAS,  each  Assignor  proposes to assign to each Assignee a ratable
portion all of the rights of the Assignor under the Credit  Agreement in respect
of a portion of its Commitment  thereunder  (the  "Assigned  Amount") such that,
after giving effect to such  assignments,  the Commitment of each Assignor shall
be the amount set forth on Schedule 1 hereto opposite such Assignor's name under
the heading  "Commitment",  and each Assignee proposes to accept such assignment
from each Assignor and assume the corresponding  obligations of such Assignor on
such terms;

         NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  mutual
agreements contained herein, the parties hereto agree as follows:

         SECTION 1.  Definitions. All capitalized terms not otherwise defined
herein shall have the respective meanings set forth in the Credit Agreement.










         SECTION 2.  Assignment.  Each Assignor hereby assigns and sells to each
Assignee a ratable  portion of such  Assignor's  Assigned Amount (and all of the
rights of such Assignor under the Credit  Agreement with respect  thereto and to
the extent thereof),  and each Assignee hereby accepts such assignment from each
Assignor and assumes all of the  obligations  of each Assignor  under the Credit
Agreement  to the extent of the portion of such  Assignor's  Assigned  Amount so
assigned  to such  Assignee.  Upon the  execution  and  delivery  hereof by each
Assignor,  each Assignee, the Company and the Agent, (i) each Assignee shall, as
of the date  hereof,  succeed  to the  rights and be  obligated  to perform  the
obligations of a Bank under the Credit  Agreement with a Commitment in an amount
equal to the amount set forth on Schedule 1 hereto opposite such Assignee's name
under the heading  "Commitment",  and (ii) each Assignor  shall,  as of the date
hereof, have a Commitment in an amount equal to the amount set forth on Schedule
1 hereto  opposite  such  Assignor's  name under the heading  "Commitment".  The
assignments provided for herein shall be without recourse to any Assignor.

         SECTION 3. Fees.  Facility fees accrued to the date hereof with respect
to the Assigned Amount of each Assignor are for the account of such Assignor and
such fees  accruing  from and  including  the date  hereof  with  respect to the
portion of the Assigned  Amount of each  Assignor  assigned to each  Assignee in
accordance  with Section 2 are for the account of such  Assignee.  Each Assignor
and  Assignee  hereby  agrees to that if it receives any amount under the Credit
Agreement which is for the account of another party hereto, it shall receive the
same for the  account  of such other  party to the extent of such other  party's
interest therein and shall promptly pay the same to such other party.

         SECTION 4.  Consent of the Company  and the Agent.  This  Agreement  is
conditioned  upon the consent of the  Company and the Agent  pursuant to Section
10.06(c) of the Credit Agreement. The execution of this Agreement by the Company
and the Agent is evidence of this  consent.  Pursuant to Section  10.06(c),  the
Company  agrees to cause the  Borrower to execute and deliver a Note  payable to
the order of each Assignee to evidence the assignment  and  assumption  provided
for herein.

         SECTION  5.   Non-Reliance   on  Assignors.   No  Assignor   makes  any
representation  or warranty in connection with, and shall have no responsibility
with respect to, the solvency, financial condition, or statements of the Company
or the Borrower,  or the validity and  enforceability  of the obligations of the
Company or the  Borrower in respect of the Credit  Agreement  or any Note.  Each
Assignee  acknowledges  that it has,  independently  and without reliance on any
Assignor,  and  based  on  such  documents  and  information  as it  has  deemed
appropriate,  made its own  credit  analysis  and  decision  to enter  into this
Agreement and will  continue to be  responsible  for making its own  independent
appraisal of the business,  affairs and  financial  condition of the Company and
the Borrower.






         SECTION 6.  Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York.

         SECTION 7. Counterparts.  This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         IN WITNESS  WHEREOF,  the  parties  have caused  this  Agreement  to be
executed and  delivered by their duly  authorized  officers as of the date first
above written.
