PARIS, June 3 (Reuters) - World number six advertising group Havas (EURC.PA) expects sales to fall by a tenth this year but aims to maintain earnings through tight cost controls.

Chairman Vincent Bollore told the group's annual meeting on Wednesday that Havas would seek acquisition opportunities but had no immediate plans for the UK's Aegis Group (AEGS.L), in which the French financier holds 29.9 percent.

A fall in sales of upto a tenth were likely to hit earnings, but Havas "should be able to retain a large part of its result in 2009", helped by tight control over variable costs, Bollore told shareholders.

"We are suffering more or less like the sector's average. I do not feel that we suffer more than others or that we will suffer more," he said.

Havas, whose clients range from France Telecom (FTE.PA) to Coca-Cola (KO.N), posted an 8.4 percent drop in first-quarter organic sales last month amid a recession-fuelled downturn in ad and marketing spend. [ID:nLF705282].

April showed "a similar trend", with sales down by around 8-10 percent, Bollore said.

Bollore is the largest shareholder of Havas, with a 32.9 percent stake. He is also the largest shareholder of media buying agency Aegis with 29.9 percent.

The situation has fuelled speculation Bollore could seek to merge the two groups to help them better compete with larger rivals such as France's Publicis (PUBP.PA) or Britain's WPP (WPP.L), the world's largest ad group by revenue.

Havas has a market capitalisation of 820 million euros ($1.2 billion) while Aegis' value is 962 million pounds ($1.6 billion).
