While all other oil-producing States in Malaysia signed the petroleum agreement, Tun Mustapha, the chief minister of Sabah, stubbornly refused, complaining of the meagre 5% oil royalty. Mustapha requested for 10-20% of revenue as royalty, failing which he would pull Sabah out of Malaysia. However, Razaleigh refused to budge. This left the Malaysian Federal government with no choice but to make another deal with Harris Salleh (who was out of favour with Tun Mustapha) to establish the political party BERJAYA and try to oust Mustapha out of power. However, Harris was reluctant to become the Chief Minister of Sabah and so Fuad Stephens was asked to assume the post of Chief Minister were BERJAYA to succeed. In the 1976 Sabah State elections, Tun Mustapha was successfully ousted by BERJAYA and Stephens was installed as Chief Minister in his place. Unfortunately, Stephens did not complete his term as he, along with five other State Ministers, died in the 1976 air crash. Harris replaced Stephens, and a week later, the oil agreement was signed. With Sabah entering into the agreement, PETRONAS had finally achieved total control of all oil and gas reserves in Malaysia.
