Source Code:  Developer shall have the right to modify and create derivative works with the Source Code.  Developer shall own any derivative works ("Derivatives") it creates to the Source Code, provided that Developer uses the Materials in accordance with the terms of this Agreement.  Developer may distribute the Derivatives, provided that all NVIDIA copyright notices and trademarks are used properly and the Derivatives include the following statement: "This software contains source code provided by NVIDIA Corporation."  

Object Code:  Developer agrees not to disassemble, decompile or reverse engineer the Object Code versions of any of the Materials.  Developer acknowledges that certain of the Materials provided in Object Code version may contain third party components that may be subject to restrictions, and expressly agrees not to attempt to modify or distribute such Materials without first receiving consent from NVIDIA.

Art Assets:  Developer shall have the right to modify and create Derivatives of the Art Assets, but may not distribute any of the Art Assets or Derivatives created therefrom without NVIDIA’s prior written consent.

Government End Users: If you are acquiring the Software on behalf of any unit or agency of the United States Government, the following provisions apply. The Government agrees the Software and documentation were developed at private expense and are provided with “RESTRICTED RIGHTS”. Use, duplication, or disclosure by the Government is subject to restrictions as set forth in DFARS 227.7202-1(a) and 227.7202-3(a) (1995), DFARS 252.227-7013(c)(1)(ii) (Oct 1988), FAR 12.212(a)(1995), FAR 52.227-19, (June 1987) or FAR 52.227-14(ALT III) (June 1987),as amended from time to time. In the event that this License, or any part thereof, is deemed inconsistent with the minimum rights identified in the Restricted Rights provisions, the minimum rights shall prevail.
No Other License. No rights or licenses are granted by NVIDIA under this License, expressly or by implication, with respect to any proprietary information or patent, copyright, trade secret or other intellectual property right owned or controlled by NVIDIA, except as expressly provided in this License.
Term:  This License is effective until terminated.  NVIDIA may terminate this Agreement (and with it, all of Developer’s right to the Materials) immediately upon written notice (which may include email) to Developer, with or without cause.

Support:  NVIDIA has no obligation to support or to continue providing or updating any of the Materials.

No Warranty:  THE SOFTWARE AND ANY OTHER MATERIALS PROVIDED BY NVIDIA TO DEVELOPER HEREUNDER ARE PROVIDED "AS IS."  NVIDIA DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

LIMITATION OF LIABILITY:  NVIDIA SHALL NOT BE LIABLE TO DEVELOPER, DEVELOPER’S CUSTOMERS, OR ANY OTHER PERSON OR ENTITY CLAIMING THROUGH OR UNDER DEVELOPER FOR ANY LOSS OF PROFITS, INCOME, SAVINGS, OR ANY OTHER CONSEQUENTIAL, INCIDENTAL, SPECIAL, PUNITIVE, DIRECT OR INDIRECT DAMAGES (WHETHER IN AN ACTION IN CONTRACT, TORT OR BASED ON A WARRANTY), EVEN IF NVIDIA HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.  THESE LIMITATIONS SHALL APPLY NOTWITHSTANDING ANY FAILURE OF THE ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.  IN NO EVENT SHALL NVIDIA’S AGGREGATE LIABILITY TO DEVELOPER OR ANY OTHER PERSON OR ENTITY CLAIMING THROUGH OR UNDER DEVELOPER EXCEED THE AMOUNT OF MONEY ACTUALLY PAID BY DEVELOPER TO NVIDIA FOR THE SOFTWARE OR ANY OTHER MATERIALS.
