A modus vivendi, or provisional understanding, signed between Israel and Egypt on 22 February 1950, and meant to complement the 1949 Israel-Egypt Armistice Agreement. In the interest of reducing tensions along the border between Israel and the Gaza Strip, the understanding establishes three zones, one on the Israeli and two on the Egyptian side of the armistice line, and limits the amount and armament of military personnel in these zones. The agreement also provided for limited territorial exchange, with Egypt receiving additional territory at the intersection of the Israel-Gaza Strip-Egypt borders, while Israel was compensated with a strip of territory along the northeastern border of the Gaza Strip.
