                           SECURITY DEED AND AGREEMENT

                  THIS SECOND AMENDMENT TO SECURITY DEED AND AGREEMENT (this
"SECOND AMENDMENT") is made effective as of the 4th day of August, 2003, by and

                                   WITNESSETH:

                  WHEREAS, Grantor executed and delivered to Grantee that
certain Security Deed and Agreement dated as of March 30, 2001, and recorded in
Deed Book Z22, beginning at Page 21, in the Office of the Clerk of the Superior
Court of Decatur County, Georgia (the "SECURITY DEED"), covering and conveying
all right, title and interest of Grantor in and to all that tract of land
described on Exhibit "A" thereto located in Decatur County, Georgia (the
"ORIGINAL

<PAGE>

ENCUMBERED PROPERTY") and securing Grantor's payment and performance of that
certain promissory note dated March 30, 2001, made by Grantor in favor of
Grantee, in the original principal amount of Ten Million and No/100 Dollars
($10,000,000.00), bearing interest and being due and payable as therein
provided, with a final payment being due thereunder on August 30, 2002
(hereinafter called the "2001 REVOLVER NOTE");

                  WHEREAS, Grantor also made and delivered to Grantee that
certain promissory note dated June 10, 2002, in the original principal amount of
Seven Million and No/100 Dollars ($7,000,000.00), bearing interest and being due
and payable as therein provided, which promissory note was issued in replacement
of and substitution for the 2001 Revolver Note with a final payment being due
thereunder on May 30, 2003 (the "2002 REVOLVER NOTE");

                  WHEREAS, in order to modify and amend the Security Deed to
reflect that the indebtedness secured by the Security Deed was evidenced by the
2002 Revolver Note, Grantor and Grantee executed that certain First Amendment to
Security Deed and Agreement dated June 10, 2002, which was recorded in Deed Book
A-26, beginning at Page 79, in the Office of the Clerk of the Superior Court of
Decatur County, Georgia (the "FIRST AMENDMENT");

                  WHEREAS, Grantor also made and delivered to Grantee that
certain promissory note dated May 30, 2003, in the original principal amount of
Seven Million and No/100 Dollars ($7,000,000.00), bearing interest and being due
and payable as therein provided, which promissory note was issued in replacement
of and substitution for the 2002 Revolver Note with a final payment being due
thereunder on May 29, 2004 (the "2003 REVOLVER NOTE");

                  WHEREAS, Grantor contemporaneously with the execution and
delivery of this Second Amendment, has also made and delivered to Grantee that
certain promissory note dated as of August 4, 2003, in favor of Grantee, in the
original principal amount of Four Hundred Ninety-Eight Thousand And No/100
Dollars ($498,000.00), bearing interest and being due and payable as therein
provided, with a final payment being due thereunder on August 1, 2013 (the "TERM
NOTE");

                  WHEREAS, after the recording of the First Amendment, Grantor
and Grantee determined that certain tracts or parcels of land in the City of
Bainbridge, Georgia lying in Land Lot 223 of the 15th Land District of Decatur
County, Georgia were inadvertently omitted from Exhibit "A" attached to the
Security Deed (such inadvertently omitted tracts or parcels of land are
described in Exhibit "A" attached hereto and made a part hereof by reference and
are hereinafter referred to as the "ADDITIONAL ENCUMBERED PROPERTY");

                  WHEREAS, Grantor and Grantee now desire to modify and amend
the Security Deed in order to reflect that: (i) the lien and security title of
the Security Deed shall also cover and convey the Additional Encumbered
Property; and (ii) to reflect that the indebtedness secured by the Security Deed
is now evidenced by the 2003 Revolver Note and the Term Note.

                  NOW THEREFORE, for and in consideration of the foregoing
premises and the sum of Ten and No/100 Dollars ($10.00) cash in hand paid by
each party hereto to the other, and

<PAGE>

other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, Grantor and Grantee hereby agree as follows:

         and payable to the order of Grantee, in the original principal amount
         of SEVEN MILLION AND NO/100 DOLLARS ($7,000,000.00), bearing interest
         and being due and payable as therein provided, with a final payment
         being due thereunder on May 30, 2003 (hereinafter called the "Note");
         (ii) any and all renewal or renewals, extension or extensions,
         replacement or replacements, modification or modifications thereof, and
         substitution or substitutions therefor, either in whole or in part;
         (iii) all advances, if any, made by Grantee pursuant to the terms of

         and agreement is hereinafter sometimes called this "Security Deed".

and (ii) by simultaneously substituting in lieu thereof the following:

                  "THIS INSTRUMENT IS A DEED passing legal title pursuant to the
         laws of the State of Georgia governing deeds to secure debt, and is
         also a security agreement granting a present and continuing security
