by Assignee to Assignor, and other valuable consideration the receipt and 
sufficiency of which are hereby acknowledged, the Board and Assignor and 
Assignee hereby agree as follows:

     1.   The Assignor does hereby assign to Assignee (a) All right, title 
and interest of Assignor under the Lease with respect to the Building and all 
right, title and interest of Assignor in and to the Building, including but 
not limited to the Assignor's option to purchase the Building after payment 
of the Bonds as provided in Section 11.2 of the Lease; and (b) the Assignor's

Office of the Judge of Probate of Madison County, Alabama.

     2.   The Assignor hereby covenants and warrants that no event of default 
currently exists under the Lease (with respect to the Building) and no event 
has occurred which with the passage of time or the giving of notice would 
constitute an event of default under the Lease (with respect to the 
Building).  The Assignee hereby covenants and warrants that it has not 
operated or used the Building in any manner that would cause an event of 
default to exist presently or to exist with the passage of time or the giving 
of notice.  The Assignor further covenants and warrants that it has full 
power and authority to assign its interest in the Lease, that such interest 
is free and clear of all liens or encumbrances, and that no consent or 
approval is necessary for it to assign such interest other than the consent 
of the Board.

     3.   The Assignee hereby assumes any and all obligations of the Assignor 
under the Lease that relate to the Building and that arise after the date of 
this Assignment.  The Board hereby releases the Assignor from any and all 
obligations under the Lease that relate to the Building and that arise after 
the date of this Assignment and the Board agrees to look solely to the 
Assignee to perform any such obligations and the Board agrees that the 
Board's remedy for any such default shall be solely a suit against Assignee 
for specific performance or for damages.

     4.   The Assignor, the Assignee and the Board hereby agree that if 
requested by the Assignee, the parties hereto shall execute such instruments 
as are necessary to remove the Building from the scope of the Lease and, at 
the direction of the Assignee the Board shall either (i) lease the Building 
to the Assignee on all the terms and conditions of the Lease, which are 
incorporated herein by reference; provided, however, with respect to said new 
lease the term Project as defined in the Lease shall mean the Building, or 
(ii) convey the Building to the Assignee in accordance with Section 11.2 of 
the Lease.

     5.   The Board and the Assignee agree that if on February 1, 



2000 or on any February 1 thereafter the Assignee pays the Board the sum of 
$278,000 plus the sum of $39,000 multiplied by the number of twelve month 
periods that have elapsed since February 1, 2000 (the "Purchase Price 
Modification Payment"), then the Board and the Assignee shall modify Section 
9(b) of the Second Amendment and Section 9(b) of the Third Amendment to 
delete the same in their entirety and substitute in lieu thereof an agreement 
that in addition to the $55,000 payment to be made pursuant to Section 11.2 
of the Original Lease, the Assignee shall pay as the purchase price described 
in such Section 11.2 an amount equal to $1,000 multiplied by the number of 
full 12 month periods that have elapsed since April 1, 1991 and the date the 
Assignee exercises the purchase option contained in Section 11.2 of the 
Original Lease.  In the event the Assignee makes the Purchase Price 
Modification Payment, the Board and the Assignee agree to execute, as soon as 
practicable, a modification of the Lease to effectuate the provisions of this 
paragraph 5.

     6.   The Primary Term of the Lease as outlined in Section 5.1 of the

     7.   The Board hereby consents to the Assignment of Assignor's interest 
in the Building to Assignee and hereby states that to its knowledge no 
default currently exists under the Lease, nor has any event occurred which 
with the passage of time or the giving of notice would constitute a default 
under the Lease.
