                  BackOfficer Friendly Software License

PREAMBLE: Network Flight Recorder has developed the BackOfficer Friendly 
computer software, a software source code kit for building intrusion 
detection systems (the "NFR Software"). Under the terms of this software 
license the NFR Software is distributed in source code form, designed to 
operate on many UNIX platforms.  The NFR Software is the product of NFR 
and is being made available to you under the terms and conditions of this 
software license agreement (the "License Agreement" or the "License").

1. LICENSE GRANT

     a. NFR hereby grants to you, and you accept, a non-exclusive,
     non-transferable license to use the NFR Software and the
     accompanying User Documentation only as authorized in this License
     Agreement (collectively, the "NFR Software and Documentation").

     b. The License permits you to use, copy and modify the NFR
     Software solely for the internal, non-commercial use of your
     organization. The NFR Software, if modified, must carry prominent
     notices stating that changes have been made and the dates of any
     such changes. You agree that you will not assign, sublicense,
     transfer, pledge, lease, rent or share your rights under the
     License.

     c. All rights not expressly granted herein are reserved to NFR.

2. LIMITATIONS ON THE LICENSE

     a.You may only use, copy and modify the NFR Software as expressly
     provided for in this Agreement. You must reproduce and include
     this Agreement and NFRs copyright notices on any copy and its
     associated documentation.

     b.You may not publish, re-publish, print, re-print or otherwise
     redistribute the NFR Software, in any form, without written
     permission from NFR. This restriction is enforced to ensure that
     NFR is the sole source of NFR Software on the Internet and that
     published versions and bug fixes are kept current.

     c.The use of the NFR Software is limited to your internal,
     non-commercial use only. The use, compilation, installation,
     modification, maintenance or operation must be performed by
     employees of your organization. If you require assistance from
     outside your organization, the NFR Software and source code are
     considered "commercial" and subject to license fees contained in a
     separate NFR Reseller Agreement. Neither the NFR Software in its
     entirety, nor any part or element of the NFR, is being licensed to
     you for use with, or in, any hardware, firmware, software program
     or other product (i) which is sold; (ii) for which you receive any
     revenue; or (iii) which is provided by you (even for free) in
     conjunction with any commercial activity. Commercial licensing of
     the NFR Software is available and is governed by the terms of the
     NFR Reseller Agreement.

3. NO NFR OBLIGATION

     You are solely responsible for maintaining the NFR Software and
     the security of the operating environment in which the NFR
     Software may be used. You are solely responsible for all of your
     costs and expenses incurred in connection with your use of the NFR
     Software or any application program thereunder, and NFR shall have
     no liability, obligation or responsibility therefor. NFR shall
     have no obligation to provide you maintenance, support, upgrades
     or new releases.

4. NO WARRANTY OF PERFORMANCE

     THE NFR SOFTWARE IS LICENSED "AS IS" WITHOUT WARRANTY, EXPRESS OR
     IMPLIED, AS TO ITS PERFORMANCE, OF MERCHANTABILITY OR FITNESS FOR
     ANY PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE RESULTS AND
     PERFORMANCE OF THE NFR IS ASSUMED BY YOU. SHOULD THE NFR PROVE
     DEFECTIVE, YOU ASSUME THE ENTIRE COST OF ALL NECESSARY SERVICING,
     REPAIR OR CORRECTION OF SAID DEFECT AND ANY CONSEQUENCES OF SUCH
     DEFECT. NFR DOES NOT WARRANT THAT THE FUNCTIONS CONTAINED IN THE
     NFR SOFTWARE WILL MEET YOUR REQUIREMENTS OR THAT THE OPERATION OF
     THE NFR SOFTWARE WILL BE UNINTERRUPTED OR ERROR-FREE. THE ENTIRE
     RISK REGARDING THE QUALITY AND PERFORMANCE OF THE NFR SOFTWARE IS
     WITH YOU.

     Some jurisdictions do not allow the exclusion of implied
     warranties, so the above exclusion may not apply to you. This
     limited warranty gives you specific legal rights, and you may also
     have other rights which vary from one jurisdiction to another.

5. LIMITATION OF LIABILITY

     Neither NFR nor any other person who has been involved in the
     creation, production or delivery of the NFR Software shall be
     liable to you or to any other person for any direct, indirect,
     special, incidental, consequential, special or exemplary damages
     or lost profits, even if NFR has been advised of the possibility
     of such damages. SOME STATES DO NOT ALLOW THE LIMITATION OR
     EXCLUSION OF LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
     THE ABOVE LIMITATION OR EXCLUSION MAY NOT APPLY TO YOU.

6. TERM

     This License is effective upon your downloading the NFR Software
     and shall continue until terminated. The grant of the License
     automatically terminate without notice if you breach any of the
     provisions hereof. You may terminate the grant of the license
     at any time by destroying all portions of the NFR Software.

7. TRADEMARK

     interest to such trademark is granted hereunder, and you agree
