give mutual aid to each other that Greece and Serbia may have contiguous
boundaries to the west of the Axios (Vardar) river and that the fixing

Starting from the mountain range of Kamena Planina (Kamma) which delimits
the high Schkoumbi to the southwest side of Ochrida Lake, the boundary
line will pass round this lake to the south; it will reach the western
shore of the Prespa Lake to the Kousko village, and passing through
the lake it will reach Dolni Dupliani on the eastern shore; from there
it will pass in the direction of the east near Rahmanli, will follow
the line of the separation of the waters between the Erigon (Tserna)
river and the Moglenica and will reach the Axios (Vardar) river at about
three kilometres to the south of Ghevgheli.
The Greeco-Bulgarian as well as the Serb.-Bulgarian boundary lines

The Serbian boundary line to the north of Ghevgheli will follow the
Axios (Vardar) river as far as the confluence of the Bregalnitza river,
which it will ascend to a point of the old Turkish-Bulgarian boundary.
The Greco-Serbian boundary line will run to the south of Kilkitch to
the north of Nigrita, through Orliako, and from there, by the Achinos
(Tachinos) lake and the Angitis (Anghista) river, will descend to the
sea a little further to the east of the harbor of Eleutherai.
All these boundary lines will be fixed in a more detailed manner and
will be inserted in the text of the aforesaid treaty of alliance.
3. The Goverments of Greece and Serbia bind themselves to proceed together,

4. Should a dissension arise with Bulgaria in regard to the boundaries
above indicated and a friendly settlement become impossible, the Governments
of Greece and Serbia reserve to themselves the right to propose jointly

and assume a menacing attitude or attempt to impose her claims by force,
the two governments, in order to secure the integrity of their possessions,
bind themselves to afford to each other military assistance and not
to conclude peace except jointly and together.

delay for the purpose of preparing and insuring the necessary defensive
measures in case one of the two States, without provocation on its part,
should be attacked by a third Power.

to guarantee for fifty years the entire freedom of the Serbian export
and import trade through the port of Salonika and the railway lines
from Salonika to uskup and Monastir .
