License Agreement

Nemetschek North America, Inc., hereafter referred to as NNA, grants the
buyer a non-exclusive license to use the software in the package according
to the terms set forth below. The software is protected by copyright laws
and international copyright treaties, as well as by other intellectual
property laws and treaties. This program has been purchased for a single,
specific operating system per serial number. It is licensed for installation
on one machine for each serial number.

The Buyer May:

Install and operate this software on one computer at a time. Make one back-
up copy of the software, which is automatically subject to this agreement.
Modify unprotected VectorScript routines provided with this software.

The Buyer May Not:

1: Make this software available to any person or entity other than employees
   who must use this software as specified above.
2: Modify or merge the software with another program, except for personal
   use as described above.
3: Disassemble, decompile, reverse engineer, or attempt in any fashion to
   discover the source code of the software.
4: Sub-license, sell, lend, rent, or lease any portion of the software. The
   buyer may, after notifying NNA, permanently transfer all (but no portion
   thereof) of the software to another person or entity, who in turn is subject
   to this agreement.
5: Operate the software on more than one computer at a time. (Site licenses
   are available from NNA for multi-station use. All sites in a site license
   must be used at one location.)

NOTE:

This software involves valuable proprietary rights of NNA and others. There
is no transfer to the buyer of any title to, or ownership of, this software;
nor is there transfer of any patent, copyright, trade secret, trade name,
trademark, or other proprietary rights related to the software. The buyer
may not violate these rights and must take appropriate steps to protect
NNA's rights. NNA may at any time replace, modify, alter, improve, enhance,
or change the software. The license and the buyer's right to use the
software terminate automatically if the buyer violates any part of this
agreement. In the event of termination of buyer's right to use the software,
all copies of the software must be destroyed or immediately returned to NNA.

Upgrades:

All upgrades or sequential versions of the program obtained under upgrade
agreements or offered at a later date in consideration of this purchase will
be considered one program under this license agreement. Under no
circumstances will the providing of upgrades be considered as permission for
this program to reside on more than one computer at any time, nor may the
buyer sub-license, sell, lend, rent, or lease any portion of former versions
of the software. Again, the license and the buyer's right to use the
software terminate automatically if the buyer violates any part of this
agreement. In the event of termination of buyer's right to use the software,
all copies of the software must be destroyed or immediately returned to NNA.

General:

NNA is not responsible for maintaining the software or for helping the buyer
in the use of said software except through the Registered User Support
Service. This agreement constitutes the entire agreement and supersedes any
prior agreement between NNA and the buyer.
