DEMO.TXT - DEMO LICENSE AGREEMENT

        I.    SOFTWARE.  This copyrighted computer software from Digital
        Communications Associates, Inc. ("DCA") has been specifically designed
        for demonstration purposes by implementing a connect time limitation
        ("Demo Program").  The title and all copyrights and ownership rights
        in the Demo Program are retained by DCA or its supplier.  You
        acknowledge that the Demo Program represents and embodies certain
        trade secrets and confidential information of DCA or its supplier.

        II.   LICENSE.  DCA grants you a limited non-exclusive license to
        (i) load a copy of the Demo Program into the memory of a single
        microcomputer (one (1) central processing unit); and (ii) use the Demo
        Program subject to the connect time limitation inherent in the Demo
        Program and subject to the terms of this Demo License Agreement.

        III.  RESTRICTIONS.  You may not sublicense, rent, lease, sell, pledge,
        or otherwise transfer or distribute the Demo Program.  You agree not
        to translate, modify, disassemble, decompile, reverse engineer, or
        create derivative works based on the Demo Program or any portion
        thereof.  This Agreement automatically terminates without notice if
        any provision of this Agreement is breached by you.

        IV.   WARRANTY DISCLAIMER.  The Demo Program is provided "AS
        IS", WITHOUT WARRANTY OF ANY KIND, either express or implied,
        INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES
        OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
        PURPOSE.  Without limitation, all warranties against infringement
        or the like respecting the Demo Program are hereby disclaimed by us.
        We do not warrant that any functions contained in the Demo Program
        will meet your requirements or that your use of the Demo Program will
        be uninterrupted or error-free.

        V.    LIMITATION OF LIABILITY.  We shall have no liability to you or
        any third party regarding the Demo Program or otherwise in warranty,
        contract, tort, or otherwise.  IN NO EVENT WILL WE BE LIABLE
        FOR ANY DIRECT, INCIDENTAL, SPECIAL INDIRECT,
        GENERAL, OR CONSEQUENTIAL DAMAGE OR LOSS OF ANY
        NATURE (such as damage to property, damages resulting from delay,
        claims of third parties, loss of profits, or injury to person) which
        may arise in connection with the use of or inability to use the
        Demo Program.  This clause shall survive failure of an exclusive
        remedy.  Some states do not allow the exclusion or limitation of
        incidental or consequential damages, so the above limitation or
        exclusion may not apply to you.

        VI.   GENERAL.  The construction and performance of this Agreement
        shall be governed by the laws of the State of Georgia.  This Agreement
        contains the entire understanding between the parties and supersedes
        any proposal or prior agreement regarding the subject matter hereof.
