5. Support for Contributions

OR OTHERWISE) UPON WHICH THE CLAIM IS BASED.

8. Miscellaneous

8.1 This Agreement will be governed by and construed in accordance with the
laws of Estonia excluding its conflicts of law provisions. Under certain
circumstances, the governing law in this section might be superseded by
the United Nations Convention on Contracts for the International Sale of
Goods ("UN Convention") and the parties intend to avoid the application
of the UN Convention to this Agreement and, thus, exclude the application
of the UN Convention in its entirety to this Agreement.

8.2 This Agreement sets out the entire agreement between You and Us for Your
Contributions to Us and overrides all other agreements or understandings.

8.3 If You or We assign the rights or obligations received through this
Agreement to a third party, as a condition of the assignment, that third
party must agree in writing to abide by all the rights and obligations in
the Agreement.

8.4 The failure of either party to require performance by the other party of
any provision of this Agreement in one situation shall not affect the right
of a party to require such performance at any time in the future.

8.5 If any provision of this Agreement is found void and unenforceable, such
provision will be replaced to the extent possible with a provision that
comes closest to the meaning of the original provision and which is
enforceable.
