British Prime Minister David Cameron has given details of an economic aid package for Northern Ireland at a news conference in Downing Street.
The announcement contained policy initiatives, concessions, flexibility with borrowing requirements and other measures.
Part of the deal is a £20m (€23.5m) fund for research and innovation to focus on the aerospace industry.
The Stormont executive will also be offered significant tracts of disused British army land to build cross-community school projects.
Mr Cameron emphasised Northern Ireland retaining EU Assisted Area Status, entitling it to top level funding from Brussels.
He also reaffirmed the British government's pledge to make a firm yes or no decision about lowering Northern Ireland's corporation tax.
The announcement will be made once the Scottish Referendum is complete.
Mr Cameron was joined at 10 Downing Street by Northern Irish First Minister Peter Robinson and Deputy First Minister Martin McGuinness.
