Without limitation of the foregoing it is emphasized that END-USER shall not be entitled to share the costs related to purchasing a Restricted Asset and then let any third party that has contributed to such purchase use such Restricted Asset (forum pooling). + +2.3 + +EXCEPT FOR EDITOR EXTENSION ASSETS, END-USER is granted a license to install and use Assets on an unlimited number of computers provided that these computers are either all (i) physically located at a single physical location ("Site") belonging to END-USER, or (ii) laptops belonging to END-USER which have been made available by END-USER to its employees that are employed at the same Site provided all such computers have appropriately licensed Unity software installed. Consequently, any Asset may only be used at particular Site or on computers assigned to END-USER's employees employed at the same Site and may only be moved to another Site subject to prior written approval from Licensor. THIS CLAUSE 2.3 DOES NOT APPLY TO ASSETS THAT IN THE UNITY ASSET STORE ARE CATEGORIZED UNDER THE HEADING "EDITOR EXTENSIONS." + +2.4 + +Editor Extensions: END-USER is granted a license to install and use any Assets which are categorized in the Asset Store as "Editor Extensions" only on one (1) computer. For the avoidance of doubt, Editor Extension Assets are licensed on a per computer basis may not be shared or used concurrently on different computers. + +2.5 + +Game Services SDKs: If END-USER downloads and integrates Services SDKs, END-USER may be required to accept a Licensor end user agreement and/or additional Licensor terms and conditions to use such services. + +2.6 + +END-USER shall pay for the license to the Assets in accordance with the payment process provided in the Asset Store. END USER shall provide customary billing and tax information such as name, billing address, credit card information and VAT number (for EU residents). END USER agrees to pay for all purchases hereby authorizes the collection of such amounts including applicable taxes by charging the credit card provided, either directly by Unity or indirectly, via a third party online payment processor. VAT numbers cannot be added or changed after the purchase is completed. If you are directed to a third party payment processor, you may be subject to terms and conditions governing use of that third party’s service and that third party’s Privacy Policy. Please review such third party’s terms and conditions and privacy policy before using the services. All sales are final and there shall be no refunds except as required by law. + +2.7 + +Some components of Assets (whether developed by Unity or third parties) may also be governed by applicable open source software licenses. In the event of a conflict between the applicable EULA and any such open source licenses, the open source software licenses shall prevail with respect to those components. + +2.8 + +With respect to any Unity licensed Assets, no modification or use of those Assets shall: (i) infringe, misappropriate, or violate a third party’s patent, copyright, trademark, trade secret, moral rights, or other intellectual property rights, or rights of publicity or privacy; (ii) violate, or encourage any conduct that would violate, any applicable law or regulation or would give rise to liability of any kind; (iii) be fraudulent, false, misleading, or deceptive; (iv) be defamatory, obscene, pornographic, vulgar, or offensive; (v) promote discrimination, bigotry, racism, hatred, harassment, or harm against any individual or group; (vi) promote violence or actions that are threatening to any other person; or (vii) promote illegal or harmful activities or substances. + +2.9 + +In this EULA, “Restricted Asset†means any Asset licensed hereunder that is designated (on prior written approval from Unity) as a “Restricted Asset†in any materials accompanying the Asset. + +3. Licensor’s Rights and Obligations +3.1 + +Licensor shall render support services to END-USER only in the event a special agreement to this effect has been entered into. + +4. Termination +4.1 + +Without prejudice to any other rights, Licensor may terminate this EULA if END-USER fails to comply with the terms and conditions of this EULA and the Terms. + +4.2 + +END-USER may terminate END-USER’s license at any time. + +4.3 + +In the event that Unity at its discretion or as a result of a decision made by any competent court or authority makes a refund to END-USER of the fees paid for any Asset, then this EULA shall terminate for such Asset. + +4.4 + +In the event of termination of this EULA, all license rights granted herein terminate and END-USER shall immediately destroy any and all copies of the Assets contained on any type of media under the control of END-USER and confirm such destruction in writing to LICENSOR. + +5. Duplication Rights/Back Up Copy +5.1 + +END-USER may not make copies of the Assets, except and only to the extent that such activity is expressly permitted under mandatory statutory applicable law. In addition Licensor acknowledges that copies of the Assets may be made when the Assets have been integrated as parts of electronic games and interactive media, cf. Section 2.3 above. + +5.2 + +After installation of one copy of the Asset pursuant to this EULA, END USER may keep the original copy of the Asset solely for back up or archival purposes. + +6. Reverse Engineering, Decompilation, and Disassembly +6.1 + +Except for Services SDKs, END USER may modify Assets.

Trademarks +7.1 + +This EULA does not grant END-USER any rights in connection with any trademarks or service marks of Licensor, Provider or Licensor's other suppliers. + +8. Upgrades and Support +8.1 + +Assets identified as upgrades replace and/or supplement the licensed Assets. + +8.2 + +Licensor may at its own discretion from time to time provide upgrades of the Assets to END USER without requesting further payment. Irrespective hereof END-USER is only entitled to licenses to upgrades if END-USER has entered into an Upgrade Agreement with Licensor. END-USER may use the upgraded Assets only in accordance with the terms of this EULA. + +8.3 + +END-USER is only entitled to support if END-USER has entered into a Support Agreement with Licensor. + +9. Copyright +9.1 + +The Assets are protected by copyright laws and international copyright treaties, as well as other intellectual property laws and treaties. + +9.2 + +All title and intellectual property rights in and to the Assets (including but not limited to any software, images, photographs, animations, graphics, 3D graphics, video, audio, music, text, tutorials, and “applets†incorporated into the Assets), the accompanying printed materials, and any copies of the Assets are owned by Licensor. All rights not expressly granted are reserved by Licensor.
