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

      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  FRP,  as Landlord,  dated  April  1,  1986,
recorded  in  Official Records Book 881, page 1458,  of  the
public  records  of  Lake County, Florida,  as  modified  by
unrecorded  First  Modification to  Mining  Lease  Agreement
dated April 1, 2001 (collectively, the "Lease").

      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.    Recitals.   The foregoing Recitals are  true  and
correct.

     2.   Extension of Term.  The term of the Lease is hereby
extended for an additional term beginning April 1, 2006, and
expiring  on  the  earlier  of the following  dates  (unless
sooner  terminated  in  accordance with  the  terms  of  the
Lease):

          (i)  March 31, 2031; or

          (ii)    When  FRI has determined in its reasonable
            discretion   that   no   economically   mineable
            reserves  of  Construction Materials  remain  on
            lands  owned  or leased by FRI adjacent  to  the
            Leased Lands.

     3.    Minimum  Royalty.  Paragraph (a)  of   Exhibit  C
attached to the Lease, setting forth the minimum royalty  to
the  paid  by  Tenant for use and possession of  the  Leased
Lands,  shall  be  modified, amended  and  restated  in  its
entirety  as  set  forth  on  Exhibit  A  attached  to  this
Amendment.  All portions of Exhibit C to the Lease which are
not





specifically amended hereby shall remain in full  force
and effect.  Provided however, that this Amendment shall  be
recorded  in  the  public records of the  county  where  the
Leased  Lands are located as a short form memorandum without
attaching thereto a copy of said Exhibit A.

     4.   Reclamation.   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.
Wherever  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, when no further  mining  or
operational  use of the lands is anticipated.  Within  three
(3)  years  of  the  date hereof, Tenant  shall  begin  such
reclamation  of  that  part of the  Leased  Lands  where  no
further mining or operational use is anticipated by Tenant.

     5.     Full  Force  and  Effect.  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 all inconsistent  terms  of
the Lease as it previously existed.

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

                          EXHIBIT A
                      Royalty Schedule
  Forming a Part of Paragraph 3 of the Amendment to Mining
                       Lease Agreement


Paragraph  (a)  of Exhibit C to the Lease is hereby  amended
and restated in its entirety as follows:

(a)   The  sum  of EIGHT THOUSAND THREE HUNDRED THIRTY-THREE
and  33/100  Dollars  ($8,333.33) per  month  as  a  minimum
royalty  shall  be  paid by Tenant to Landlord  during  each
month  from the effective date hereof through September  30,
2010.   Beginning  on  October 1,  2010,  and  on  each  5th
anniversary thereof during the term of this Lease (each such
date   being  referred  to  herein  as  a  "Minimum  Royalty
Adjustment Date"), the minimum monthly royalty payment shall
be adjusted proportionately with any changes in the Producer
Price  Index for Construction Sand, Gravel and Crushed Stone
(Commodity Code 13-21) (1982=100) (the "PPI"), as  published
by  the U. S. Department of Labor during the preceding  five
year  period  of  the  Lease term.  For  the  adjustment  on
October 1, 2010, the calendar year 2005 shall be used as the
base year.  For each subsequent adjustment after October  1,
2010, the base year for the PPI adjustment shall be the last
calendar  year  of  the five year period  which  immediately
preceded  the  five  year  period  that  ended  on  the  day
immediately  preceding the Minimum Royalty Adjustment  Date.
The minimum royalty payment as adjusted on each Minimum Rent
Adjustment  Date  shall  then  become  the  minimum  monthly
royalty payment for each month of the next five years of the
term,  until the next Minimum Royalty Adjustment Date,  when
the  minimum  royalty is again adjusted as provided  herein.
Notwithstanding  any  of the above provisions,  the  minimum
monthly  royalty  shall  never be less  than  $8,333.33  per
month.   If  the index required for the calculation  of  the
royalty  adjustment  is  not  available  at  the  time   the
adjustment is to become effective, Tenant shall continue  to
pay  the minimum royalty in effect for the preceding  month,
until the adjustment can be computed, at which time Landlord
shall  advise  Tenant and Tenant shall  pay  the  additional
amount  that  would  have been required,  had  the  adjusted
royalty   figure  been  available  on  the  Minimum  Royalty
Adjustment  Date.   The  payment  of  each  month's  minimum
royalty shall be made within twenty (20) days following  the
beginning  of  the calendar month of the  Lease  term.   All
minimum royalties paid by Tenant may be recovered by  Tenant
as  provided in the subsequent provisions of this Exhibit C;
provided,  however,  such  minimum  royalties  may  only  be
recovered during Tenant's fiscal year in which such payments
are made.
