Unless stated otherwise, the Library Developer is the sole owner of the Product, and the Library Developer is presumed to be the holder of the Intellectual Property Rights in the Product, including, without limitation, such aspects of the Software as its code, structure, sequence, organization, "look and feel", programming language, and compilations of command names, descriptors, and data. Use of the Product, unless pursuant to the terms of a license granted by the Library Developer or as otherwise authorized by law, is an infringement of Intellectual Property Rights.

Notwithstanding the obligation to provide acknowledgment stated above, no other right to use the names, marks, or other distinctions of the Product, WRI, or the Library Developer is granted.

Permitted Uses and Installations

Subject to the terms of this Agreement and Your acceptance thereof, WRI grants You a non-exclusive license to use the Product on behalf of the Library Developer. This Agreement terminates in the event that You receive a license to use an upgraded version of the Product in place of this Product, which upgrade, as well as any other improvement or enhancement, neither WRI nor the Library Developer is under any obligation to provide. Should You receive an upgraded version of the Product and desire to continue concurrent use of the older version, this License Agreement and License Certificate shall merge with the upgraded License Agreement and License Certificate such that Your continued use will be allowed under the terms, conditions, and restrictions therein. Your license to use the Product terminates on the license expiration date, if one is indicated, or upon notice of a material breach that is not cured within 30 days of receipt of notice. Provisions of this Agreement that by their nature express ongoing rights or obligations shall survive the expiration or termination of this Agreement. You are also authorized to:

  1. for a Single-Machine License Class, install and use Software only from a single storage device (e.g. a hard-disk drive);
  2. for a Network License Class, install and use the Software from storage devices that are located at the physical site of Product Registration and are accessible by the Network License Controller; maintain one archival copy of the Software on storage media (such as a DVD or USB drive);
  3. undertake a System Transfer only if Your System Modeler service level permits the transfer; You contact WRI Customer Service and, at its direction, complete and submit a System Transfer Form; and You pay any license cost difference or applicable transfer fee;
  4. transfer the Product subject to this Agreement and to a different Licensee only if (1) the transferee's use of the Software falls into the same System Modeler service level; (2) You contact WRI Customer Service to convey relevant information and certify that You have destroyed or given to the transferee all copies of the Software and other elements of the Product in Your possession; (3) You pay any license cost difference or applicable transfer fee; and (4) the transferee accepts all the terms and conditions of this Agreement; and
  5. use Remote Access to a License, if You are a Primary User of a Single-Machine License or a Registered User on a Network License that would be eligible to use the License directly.

Limited Warranty and Disclaimer

WRI warrants that the Product shall be free from defects in the physical media for a period of 90 days following the date of purchase when used under normal conditions. You acknowledge that WRI shall provide, as Your sole remedy for breach of this warranty, another copy of the physical media. The foregoing warranty is in lieu of all other warranties, express or implied.

WRI does not warrant that the Product is free from all errors and/or omissions, and in fact it may contain them. Except as specifically set forth above, the Product is provided "as is". WRI makes no representations or warranties, express, statutory, or implied, with respect to the Product or the Software contained in the Product or data accessed thereby, including, without limitation, any implied warranties of merchantability, interoperability, or fitness for a particular purpose, all of which are expressly disclaimed. WRI does not warrant that the functions contained in the Product will meet Your requirements or that the operation of the Product will be uninterrupted or error free.

WRI, and its agents, representatives, licensors, and independent contractors, shall not be obligated to provide or liable, under any circumstances, for providing information on or corrections to errors and/or omissions discovered at any time in the Product, whether or not they were aware of the errors and/or omissions. WRI does not recommend the use of the Product for applications in which errors and/or omissions could threaten life, injury, or significant loss. Some states do not allow the exclusion of implied warranties, so this may not apply to You. This warranty gives You specific legal rights, and You may also have other rights that vary from state to state. This Agreement is governed by the laws of the State of Illinois in the United States of America without effect to any choice of law provisions.

Limited Damages

In no event shall WRI or its agents, representatives, licensors, and independent contractors be liable for any lost profits, lost use, lost benefits, or any consequential, indirect, incidental, special, or punitive damages, whether in contract, tort, or otherwise, even if WRI has been advised of the possibility of such damages. WRI's cumulative liability to You or any other party for any loss or damages resulting from any claims, demands, actions, or otherwise arising out of or relating to this Agreement shall not exceed the license fee paid for the Product. Some states do not allow certain limitations of damages, so the above limitations may not apply to You.

Use, duplication, or disclosure of this Software is subject to restrictions set forth in FAR 52.227-19 and DFAR 227.7200–227.7202-4, as applicable.
