Anadarko Petroleum Company announced its intention to continue negotiations with Houston-based petroleum company Occidental April 29 despite its announcement earlier this month it would enter an acquisition agreement with Chevron.

According to an Anadarko news release, the company is resuming its negotiations with Occidental Petroleum Company.

Anadarko's board of directors unanimously agreed the Occidental proposal "could reasonably be expected to result in a 'Superior Proposal' as defined in the Chevron Merger Agreement," according to the news release.

Occidental is reportedly offering to acquire Anadarko in a transaction worth $38 in cash and 0.6094 of a share of Occidental common stock per share of Anadarko stock. Chevron's current offer is reportedly valued at $16.25 in cash and 0.3869 of a share of Chevron stock per share of Anadarko stock.

Occidental filed its offer to Anadarko on April 24.

"The Anadarko board's determination allows Anadarko to resume negotiations with Occidental in accordance with the Chevron Merger Agreement," the release states. The board reaffirmed its recommendation to proceed with the existing transaction with Chevron, the April 29 release stated.
