* Gazprom concessions include linking gas prices to hub prices
* Gazprom offers to scrap territorial curbs against re-selling gas
* Settlement of EU case would stave off possible hefty fine (Adds European Commission, Gazprom decline comment)

BRUSSELS, April 3 (Reuters) - The European Union and Gazprom are poised to settle a long-running antitrust case after the Russian gas company agreed to price reforms and to allow rivals to gain a foothold in eastern Europe, people familiar with the matter said.
A decision by the European Commission could come as early as this month although the timing could still slip, the people said. A settlement would allow Gazprom to avoid a possible fine of as much as 10 percent of its global turnover.
The seven-year-old case underlines the rocky relationship between Europe and Russia, which have clashed over Ukraine, Syria and, most recently, a nerve attack against a former Russian spy living in England that resulted in expulsions of diplomats on both sides.
Last year, state-owned Gazprom, which supplies a third of the EU’s gas, offered to link prices to benchmarks such as western European gas market hubs and border prices in France, Germany and Italy, and allow price reviews every two years.
The company also pledged to scrap all contractual restrictions which bar clients from reselling its gas and let the Bulgarian transmission network operator take charge of the Balkan country’s gas flows to Greece.
Gazprom has tweaked its original proposal after negative feedback from EU countries and customers but the main elements remain unchanged, according to a recent draft seen by Reuters.
Revisions have been mainly technical such as lower service fees charged by Gazprom which could result in its clients saving millions of euros.
Both the Commission and Gazprom declined to comment.
Gazprom found itself in the EU antitrust crosshairs in 2011 after regulators raided about 20 offices of its customers in eastern and central Europe, seizing more than 150,000 documents.
At issue was whether Gazprom had imposed unfair prices by linking gas price to oil prices, divided up gas markets by hindering the free flow of gas across EU countries and prevented the diversification of the supply of gas.
