             AMENDMENT TO MINING LEASE AGREEMENT
             -----------------------------------
                          (Grandin)

      This  Amendment to Mining Lease Agreement  is  entered
into by and between FLORIDA ROCK PROPERTIES, INC. ("FRP") as
Landlord,  and  FLORIDA ROCK INDUSTRIES,  INC.  ("FRI"),  as
Tenant,  this 4th day of October, 2006.

                          RECITALS:
                          ---------

      FRI, as Tenant, entered into that certain Mining Lease
Agreement  with  Grandin  Land,  Inc.,  as  Landlord,  dated
September  1, 1986, recorded in Official Records Book  0539,
page  1908, of the public records of Putnam County,  Florida
(the  "Lease").  FRP is successor by merger to Grandin  Land
Sales,  Inc.,  and is the Landlord under the Lease,  as  set
forth  in Assumption Agreement recorded in Official  Records
Book 539, page 1931, of the public records of Putnam County,
Florida.

      FRI  and  FRP desire to amend the Lease as  set  forth
below.

      NOW  THEREFORE, in consideration of $10.00  and  other
good and valuable consideration, the receipt and sufficiency
of  which  is hereby acknowledged, the undersigned agree  as
follows:

     1.   The foregoing Recitals are true and correct.

     2.   Landlord and Tenant hereby agree to modify, amend and
restate  in its entirety the first full paragraph of Section
II(b) of Exhibit "D" attached to the Lease, as follows:

     (b)    Releases.    Tenant will release mined  out  and
     reclaimed  land  and lakes to Landlord for  development
     when   in  the  Tenant's  discretion,  development   by
     Landlord  will not impair the then current  or  planned
     future mining activities.

     3.    Tenant agrees that when mining is complete and no
further mining or operational use of the land is anticipated
by  Tenant, Tenant shall reclaim the land in compliance with
either the reclamation standards of the State of Florida  or
the  reclamation  standards of the county where  the  Leased
Lands  are  located,  whichever is stricter.  Whereever  any
portions  of  the  Leased Lands are  grandfathered  so  that



reclamation   is  not  required, Tenant  shall  nevertheless
reclaim  the lands in accordance with reclamation  standards
of  the  State  of  Florida  as if  the  same  were  legally
applicable,  where no further mining or operational  use  of
the  lands is anticipated.  Reclamation will include sloping
banks  and  planting trees, but Landlord  acknowledges  that
reclamation  will  not  restore the  land  to  its  original
condition.   Within three (3) years from  the  date  hereof,
Tenant shall begin its reclamation of areas where mining  is
now  complete, and no further mining or operational  use  of
the land is anticipated by Tenant.

     4.     Landlord and Tenant acknowledge that  the  Lease
continues  in full force and effect in accordance  with  its
terms,   as   modified  herein.   In  the   event   of   any
inconsistency  between the provisions of this Amendment  and
the  provisions  of the Lease as it existed  prior  to  this
Amendment, the terms of this Amendment shall prevail and  be
deemed  to  modify inconsistent terms of  the  Lease  as  it
previously existed.



               [Signatures on Following Pages]



      IN  WITNESS WHEREOF, the undersigned have entered into
this Amendment as of the date set forth above.
