(b) If Clauses 1 and 2 of paragraph (a) of this article do not apply with respect to an individual's services, the agency of any jurisdiction may approve, subject to such conditions as it may prescribe or as may be prescribed by its unemployment insurance law, an election by such individual's employer pursuant to which such individual's entire services for that employer shall be deemed to be insured employment under the unemployment insurance law of such jurisdiction. ARTICLE V The Agency of any jurisdiction may perform services for the agency of any other jurisdiction in the taking and development of any claim for benefits by an individual absent from such latter jurisdiction and desirous of claiming benefits under the unemployment insurance law of such jurisdiction. ARTICLE VI (a) To avoid the duplication of unemployment insurance payments with respect to the same period of unemployment, no benefits shall be payable on the basis of a claim filed through an agency of another jurisdiction unless the claimant's benefit rights, if any, under the law of the jurisdiction in which he files his claim shall have been exhausted or otherwise terminated. (b) If, after such rights have been exhausted or otherwise terminated, any such individual has rights under the unemployment insurance laws of two or more jurisdictions, such individual may be required to exhaust or otherwise terminate his rights to benefits under such other laws in such order as may be determined jointly by the Social Security Board of the United States of America and the Unemployment Insur- ance Commission of Canada, to be reasonable and just as between all affected interests. ARTICLE VII This agreement may be amended by mutual arrangement evidenced by an exchange of notes between the two Governments, and may be terminated by either Government after sixty days notice to the other Government. 1453 Services for agency of another jurisdic- tion.
