warranty, indemnity, or other liability obligations and/or rights consistent with this
License Agreement. However, in accepting such obligations, You may act only on Your own
behalf and on Your sole responsibility, not on behalf of Licensor or any other
Contributor, and you hereby agree to indemnify, defend, and hold Licensor and each other
Contributor (and their successors or assigns) harmless for any liability incurred by, or
claims asserted against, such Licensor or Contributor (and their successors or assigns) by
