　　7. Disclaimer of Warranty. Unless required by applicable law or       agreed to in writing, Licensor provides the Work (and each       Contributor provides its Contributions) on an "AS IS" BASIS,       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or       implied, including, without limitation, any warranties or conditions       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A       PARTICULAR PURPOSE.

However, in accepting such obligations, You may act only       on Your own behalf and on Your sole responsibility, not on behalf       of any other Contributor, and only if You agree to indemnify,       defend, and hold each Contributor harmless for any liability       incurred by, or claims asserted against, such Contributor by reason       of your accepting any such warranty or additional liability.
