In 1948 (1367/68 AH), Aramco invoked an Article of the Supplemental Agreement of 1939 (1357/58 AH) by selling a 30% interest to Standard Oil of New Jersey and a 10% interest to Socony Vacuum.
The redistributed ownership of Aramco was then Standard Oil of California (now known as California Standard) - 30%; Texas Oil Company (now known as Texaco) - 30%; Standard Oil of New Jersey (later known as Exxon) - 30%; and Socony Vacuum (later known as Mobil Oil) - the last 10%.
(In 1998, Exxon and Mobil signed a definitive agreement to merge and form a new company called Exxon Mobil Corporation.)
