6. Base Model Rights. The Work incorporates the Base Model. Nothing in this
License limits, restricts, conditions, or modifies any rights You have in the
Base Model under the Base Model License, and the Base Model remains available
to You from its licensor under the Base Model License. Sections 5 and 12 of
this License apply solely to the Swift Contribution and to the Work or any
Derivative Work to the extent it contains, incorporates, or is derived from the
Swift Contribution.

7. Submission of Contributions. Unless You explicitly state otherwise, any
Contribution intentionally submitted for inclusion in the Work by You to the
Licensor shall be under the terms and conditions of this License, without any
additional terms or conditions. Notwithstanding the above, nothing herein shall
supersede or modify the terms of any separate license agreement you may have
executed with Licensor regarding such Contributions.

8. Trademarks. This License does not grant permission to use the trade names,
trademarks, service marks, or product names of the Licensor (including "UkisAI"
and "Swift"), except for the reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.

9. 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. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any risks
associated with Your exercise of permissions under this License.

10. Limitation of Liability. In no event and under no legal theory, whether in
tort (including negligence), contract, or otherwise, unless required by
applicable law (such as deliberate and grossly negligent acts) or agreed to in
writing, shall any Contributor be liable to You for damages, including any
direct, indirect, special, incidental, or consequential damages of any
character arising as a result of this License or out of the use or inability to
use the Work (including but not limited to damages for loss of goodwill, work
stoppage, computer failure or malfunction, or any and all other commercial
damages or losses), even if such Contributor has been advised of the
possibility of such damages.

11. Accepting Warranty or Additional Liability. While redistributing the Work
or Derivative Works thereof, You may choose to offer, and charge a fee for,
acceptance of support, warranty, indemnity, or other liability obligations
and/or rights consistent with this License. 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.

12. Termination. This License will terminate automatically and immediately if
You fail to comply with any of its terms and conditions. Upon termination, You
must cease all use of the Swift Contribution and of any Work or Derivative
Works containing it, and delete all copies in Your possession. Termination does
