      -------------------------
     Disclosure Schedule 3.19, both of which arise out of the provision of
     Enhanced Universal Emergency Number Services by Gulf Telephone Company to
     the Baldwin County Emergency Communications District; (ii) Buyer does not
     consent to the sale, transfer or liquidation after the date hereof of any

     Schedules, including, but not limited to, the sale of any additional shares
     of the common stock of Wireless One; and (iii) Buyer does not waive any
     breach of a material representation, warranty or covenant resulting from
     (A) any encumbrance or restriction on transfer affecting the GCSI Shares
     disclosed in the summary stock register and stock certificates, including,
     but not limited to, any option of the ESOP to acquire certain shares from
     the John McClure Snook Irrevocable and Testamentary Trusts, and (B) any

     receives coverage over any matters that constitute, or could constitute,
     defects in the good and marketable title to the Real Property, other than
     Permitted Liens, Buyer will accept such matters relating to the Real
     Property. To the extent affirmative coverage cannot be reasonably obtained
     for such matters without the payment of money other than that required to
     pay for the title insurance policy(ies), Buyer does not waive any potential
     breach of the representation and warranty in Section 3.8 relating to title.

          (e) Notwithstanding anything in this Agreement to the contrary, the
     mere inclusion of an item in tile Disclosure Schedules as an exception to a
     representation or warranty shall not be deemed an admission by GCSI that
     such item represents a material exception or material fact, event or
     circumstance or that such item has had or could be reasonably expected to
     have a Material Adverse Effect.

     The Agreement is amended by deleting clause (iv) of paragraph (e) of
Section 7.1 in its entirety.

     IN WITNESS WHEREOF, the parties hereto have executed this Second Amendment
to the Agreement on the date first written.
