3DFX GLIDE Source Code General Public License

1. PREAMBLE

This license is for software that provides a 3D graphics application program
interface (API).The license is intended to offer terms similar to some standard
General Public Licenses designed to foster open standards and unrestricted
accessibility to source code. Some of these licenses require that, as a condition
of the license of the software, any derivative works (that is, new software
which is a work containing the original program or a portion of it) must be
available for general use, without restriction other than for a minor transfer
fee, and that the source code for such derivative works must likewise be made
available. The only restriction is that such derivative works must be subject
to the same General Public License terms as the original work.

This 3dfx GLIDE Source Code General Public License differs from the standard
licenses of this type in that it does not require the entire derivative work
to be made available under the terms of this license nor is the recipient
required to make available the source code for the entire derivative work.
Rather, the license is limited to only the identifiable portion of the derivative
work that is derived from the licensed software. The precise terms and conditions
for copying, distribution and modification follow.

2. DEFINITIONS

2.1 This License applies to any program (or other "work") which contains a
notice placed by the copyright holder saying it may be distributed under the
terms of this 3dfx GLIDE Source Code General Public License.

2.2 The term "Program" as used in this Agreement refers to 3DFX's GLIDE source
code and object code and any Derivative Work.

2.3 "Derivative Work" means, for the purpose of the License, that portion
of any work that contains the Program or the identifiable portion of a work
that is derived from the Program, either verbatim or with modifications and/or
translated into another language, and that performs 3D graphics API operations.
It does not include any other portions of a work.

2.4 "Modifications of the Program" means any work, which includes a Derivative
Work, and includes the whole of such work.

     2.5 "License" means this 3dfx GLIDE Source Code General Public License.

2.6 The "Source Code" for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source code means
all the source code for all modules it contains, any associated interface
definition files, and the scripts used to control compilation and installation
of the executable work.

     2.7 "3dfx" means 3dfx Interactive, Inc.

3. LICENSED ACTIVITIES

3.1 COPYING - You may copy and distribute verbatim copies of the Program's
Source Code as you receive it, in any medium, subject to the provision of
section 3.3 and provided also that:

(a) you conspicuously and appropriately publish on each copy an appropriate
copyright notice (3dfx Interactive, Inc. 1999), a notice that recipients who
wish to copy, distribute or modify the Program can only do so subject to this
License, and a disclaimer of warranty as set forth in section 5;

(b) keep intact all the notices that refer to this License and to the absence
of any warranty; and

(c) do not make any use of the GLIDE trademark without the prior written permission
of 3dfx, and

(d) give all recipients of the Program a copy of this License along with the
Program or instructions on how to easily receive a copy of this License.

3.2 MODIFICATION OF THE PROGRAM/DERIVATIVE WORKS - You may modify your copy
or copies of the Program or any portion of it, and copy and distribute such
modifications subject to the provisions of section 3.3 and provided that you
also meet all of the following conditions:

(a) you conspicuously and appropriately publish on each copy of a Derivative
Work an appropriate copyright notice, a notice that recipients who wish to
copy, distribute or modify the Derivative Work can only do so subject to this
License, and a disclaimer of warranty as set forth in section 5;

(b) keep intact all the notices that refer to this License and to the absence
of any warranty; and (c) give all recipients of the Derivative Work a copy
of this License along with the Derivative Work or instructions on how to easily
receive a copy of this License.

(d) You must cause the modified files of the Derivative Work to carry prominent
notices stating that you changed the files and the date of any change.

(e) You must cause any Derivative Work that you distribute or publish to be
licensed at no charge to all third parties under the terms of this License.

(f) You do not make any use of the GLIDE trademark without the prior written
permission of 3dfx.

(g) If the Derivative Work normally reads commands interactively when run,
you must cause it, when started running for such interactive use, to print
or display an announcement as follows:

"COPYRIGHT 3DFX INTERACTIVE, INC. 1999, ALL RIGHTS RESERVED THIS SOFTWARE
IS FREE AND PROVIDED "AS IS," WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED. THERE IS NO RIGHT TO USE THE GLIDE TRADEMARK WITHOUT PRIOR WRITTEN
PERMISSION OF 3DFX INTERACTIVE, INC. SEE THE 3DFX GLIDE GENERAL PUBLIC LICENSE
FOR A FULL TEXT OF THE DISTRIBUTION AND NON-WARRANTY PROVISIONS (REQUEST COPY
FROM INFO@3DFX.COM)."

(h) The requirements of this section 3.2 do not apply to the modified work
as a whole but only to the Derivative Work. It is not the intent of this License
to claim rights or contest your rights to work written entirely by you; rather,
the intent is to exercise the right to control the distribution of Derivative
Works.

     3.3 DISTRIBUTION

(a) All copies of the Program or Derivative Works which are distributed must
include in the file headers the following language verbatim:

"THIS SOFTWARE IS SUBJECT TO COPYRIGHT PROTECTION AND IS OFFERED ONLY PURSUANT
TO THE 3DFX GLIDE GENERAL PUBLIC LICENSE. THERE IS NO RIGHT TO USE THE GLIDE
TRADEMARK WITHOUT PRIOR WRITTEN PERMISSION OF 3DFX INTERACTIVE, INC. A COPY
OF THIS LICENSE MAY BE OBTAINED FROM THE DISTRIBUTOR OR BY CONTACTING 3DFX
INTERACTIVE INC (info@3dfx.com). THIS PROGRAM. IS PROVIDED "AS IS" WITHOUT
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED. SEE THE 3DFX GLIDE GENERAL
PUBLIC LICENSE FOR A FULL TEXT OF THE NON-WARRANTY PROVISIONS.

USE, DUPLICATION OR DISCLOSURE BY THE GOVERNMENT IS SUBJECT TO RESTRICTIONS
AS SET FORTH IN SUBDIVISION (C)(1)(II) OF THE RIGHTS IN TECHNICAL DATA AND
COMPUTER SOFTWARE CLAUSE AT DFARS 252.227-7013, AND/OR IN SIMILAR OR SUCCESSOR
CLAUSES IN THE FAR, DOD OR NASA FAR SUPPLEMENT. UNPUBLISHED RIGHTS RESERVED
UNDER THE COPYRIGHT LAWS OF THE UNITED STATES.

          COPYRIGHT 3DFX INTERACTIVE, INC. 1999, ALL RIGHTS RESERVED"

(b) You may distribute the Program or a Derivative Work in object code or
executable form under the terms of Sections 3.1 and 3.2 provided that you
also do one of the following:

(1) Accompany it with the complete corresponding machine-readable source code,
which must be distributed under the terms of Sections 3.1 and 3.2; or,

(2) Accompany it with a written offer, valid for at least three years, to
give any third party, for a charge no more than your cost of physically performing
source distribution, a complete machine-readable copy of the corresponding
source code, to be distributed under the terms of Sections 3.1 and 3.2 on
a medium customarily used for software interchange; or,

(3) Accompany it with the information you received as to the offer to distribute
corresponding source code. (This alternative is allowed only for noncommercial
distribution and only if you received the program in object code or executable
form with such an offer, in accord with Subsection 3.3(b)(2) above.)

(c) The source code distributed need not include anything that is normally
distributed (in either source or binary form) with the major components (compiler,
kernel, and so on) of the operating system on which the executable runs, unless
that component itself accompanies the executable code.

(d) If distribution of executable code or object code is made by offering
access to copy from a designated place, then offering equivalent access to
copy the source code from the same place counts as distribution of the source
code, even though third parties are not compelled to copy the source along
with the object code.

(e) Each time you redistribute the Program or any Derivative Work, the recipient
automatically receives a license from 3dfx and successor licensors to copy,
distribute or modify the Program and Derivative Works subject to the terms
and conditions of the License. You may not impose any further restrictions
on the recipients' exercise of the rights granted herein. You are not responsible
for enforcing compliance by third parties to this License.

(f) You may not make any use of the GLIDE trademark without the prior written
permission of 3dfx.

(g) You may not copy, modify, sublicense, or distribute the Program or any
Derivative Works except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program or any Derivative
Works is void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under this
License will not have their licenses terminated so long as such parties remain
in full compliance.

4. MISCELLANEOUS

4.1 Acceptance of this License is voluntary. By using, modifying or distributing
the Program or any Derivative Work, you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Program or works based on it. Nothing else grants you permission to modify
or distribute the Program or Derivative Works and doing so without acceptance
of this License is in violation of the U.S. and international copyright laws.

4.2 If the distribution and/or use of the Program or Derivative Works is restricted
in certain countries either by patents or by copyrighted interfaces, the original
copyright holder who places the Program under this License may add an explicit
geographical distribution limitation excluding those countries, so that distribution
is permitted only in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of this License.

4.3 This License is to be construed according to the laws of the State of
California and you consent to personal jurisdiction in the State of California
in the event it is necessary to enforce the provisions of this License.
