AMSTERDAM, May 12 (Reuters) - As U.S. paintmaker PPG Industries considers whether to keep pursuing Dutch peer Akzo Nobel after being rebuffed three times, the fate of the Dulux owner is moving into uncharted territory.

Lawyers and M&A advisors say an outright hostile takeover remains unlikely, but point to other potential outcomes.

While PPG still hopes to broker a takeover deal with support from a large proportion of Akzo's own shareholders, Akzo's boards are determined to remain independent and plan to issue extra dividends and sell a chemicals division to keep investors happy and suitors at bay.

Here's a look at pivotal moments to come and how they may play out:

On May 22, Amsterdam's Enterprise Chamber, the Netherlands' top business court, will hear a petition by Akzo investor Elliott Advisors calling for the court to appoint an investigator to examine possible mismanagement by the Akzo boards.

Elliott will also request permission to convene an extraordinary meeting (EGM) of shareholders to vote on dismissing Akzo Chairman Antony Burgmans, a former Unilever CEO.

Opinions differ on Elliott's chances: Dutch law explicitly grants shareholders the right to call an EGM, though the court may decide Akzo boards' decisions have been defensible and there is no need for a meeting to consider Burgmans' dismissal.

Given the importance of the case, the court is likely to act quickly and make its decision before the end of the month, though the timing is tight.

TIMING OF COURT DECISION CRUCIAL

PPG must file papers detailing its intent to bid for Akzo to the Dutch Financial Markets Authority (AFM) by June 1, or agree to walk away for at least six months.

That filing, which is not made public, costs several million euros to prepare and includes details such as the intended offer price and proof PPG can finance its bid.

If the court rejects Elliott's request before June 1, that would strengthen the hand of Akzo's management and supervisory boards, and PPG may decide walking away without filing is the prudent course of action.

But if the court hasn't ruled by June 1, or rules in Elliott's favour, PPG may file with conditions for its offer, including a 95 percent threshold of shareholder approval.

It will take regulators some time - from days to weeks - to review and approve PPG's bidding papers.
