8. Subject to the provisions of its domestic law and its extradition treaties, the requested Party may, upon being satisfied that the circumstances so warrant and are urgent, and at the request of the requesting Party, take a person whose ex- tradition is sought and who is present in its territory into custody or take other appropriate measures to ensure his presence at extradition proceedings.
9. Without prejudice to the exercise of any criminal jurisdiction estab- lished in accordance with its domestic law, a Party in whose territory an alleged offender is found shall:
(a) If it does not extradite him in respect of an offence established in ac- cordance with article 3, paragraph 1, on the grounds set forth in article 4, para- graph 2, subparagraph (a), submit the case to its competent authorities for the purpose of prosecution, unless otherwise agreed with the requesting Party;
(b) If it does not extradite him in respect of such an offence and has estab- lished its jurisdiction in relation to that offence in accordance with article 4, paragraph 2, subparagraph (b), submit the case to its competent authorities for the purpose of prosecution, unless otherwise requested by the requesting Party for the purposes of preserving its legitimate jurisdiction.
10. If extradition, sought for purposes of enforcing a sentence, is refused because the person sought is a national of the requested Party, the requested Party shall, if its law so permits and in conformity with the requirements of such law, upon application of the requesting Party, consider the enforcement of the sen- tence which has been imposed under the law of the requesting Party, or the re- mainder thereof.
11. The Parties shall seek to conclude bilateral and multilateral agree- ments to carry out or to enhance the effectiveness of extradition.
12. The Parties may consider entering into bilateral or multilateral agree- ments, whether ad hoc or general, on the transfer to their country of persons sen- tenced to imprisonment and other forms of deprivation of liberty for offences to which this article applies, in order that they may complete their sentences there.
