Article III. If one, or two, of the high contracting parties, without direct provocation on their part, should chance to be attacked and to be engaged in a war with two or more Great Powers nonsignatory to the present treaty, the casus foederis will arise simultaneously for all the high contracting parties.
Article IV. In case a Great Power nonsignatory to the present treaty should threatened the security of the states of one of the high contracting parties, and the threatened party should find itself forced on that account to make war against it, the two others bind themselves to observe towards their ally a benevolent neutrality. Each of them reserves to itself, in this case, the right to take part in the war, if it should see fit, to make common cause with its ally.
Article V. If the peace of any of the high contracting parties should chance to be threatened under the circumstances foreseen by the preceding articles, the high contracting parties shall take counsel together in ample time as to the military measures to be taken with a view to eventual cooperation.
They engage henceforward, in all cases of common participation in a war, to conclude neither armistice, nor peace, nor treaty, except by common agreement among themselves.
Article VI. The high contracting parties mutually promise secrecy as to the contents and existence of the present treaty.
Article VII. The present treaty shall remain in force during the space of five years, dating from the day of the exchange of ratifications.
Article VIII. The ratifications of the present treaty shall be exchanged at Vienna within three weeks [ . . . ].
