| license to make, have made, use, offer to sell, sell, import, |
| transfer, and otherwise run, modify and propagate the contents of this |
| implementation of the VoiceEngine Framework and the VideoEngine |
| Framework included in the WebRTC package, where such license applies |

| WebRTC package or any code incorporated within this implementation of |
| the media components included in the WebRTC package constitutes direct |
| or contributory patent infringement, or inducement of patent |

| for this implementation of the VoiceEngine Framework and the |
| VideoEngine Framework included in the WebRTC package shall terminate |
| as of the date such litigation is filed. |
