London: Benson and Hedges cup holders Gloucestershire - which cemented its quarter-final berth at the weekend - was handed a home tie with Durham after Sunday's matches were completed.
Somerset will take on Yorkshire, while Sussex meets Surrey and Nottinghamshire is due to play Warwickshire. One of the matches will take place on May 22, with the other three going ahead the following day. The fourth tie sees Nottinghamshire host Warwickshire.
Everyone went home happy at Headingley as Yorkshire and Durham both qualified, with the hosts prevailing by 30 runs. Durham did enough in defeat - 227 for four in reply to 257 for seven - to edge out Leicestershire from the northern section.
Yorkshire had the batting of Darren Lehmann and Anthony McGrath to thank for pushing their run rate up sufficiently to reach the quarter-finals by the back door.
Yorkshire's fine batting return owed much to a 115-run third-wicket stand between Lehmann (88) and McGrath (43).
Leicestershire scored a 21-run success over Derbyshire at Grace Road - but missed out on qualification on run rate.
Nottinghamshire beat Lancashire by seven wickets at Trent Bridge to maintain their 100 per cent record at the top of the group and set up the home draw with Warwickshire.
In the Midland/ West/ Wales section, there was an exciting finish at New Road as Warwickshire edged out Worcestershire by one wicket. In the battle of the bottom two, Northamptonshire beat winless Glamorgan by eight wickets at Cardiff.
At Taunton, Somerset set up the home clash with Yorkshire by beating neighbours Gloucestershire by 108 runs at Taunton.
In the southern section, Essex beat Middlesex by 71 runs at Chelmsford.
At West End, qualifiers Sussex piled on the misery for Hampshire, winning by 60 runs.
At Canterbury, Kent won a high-scoring game with Surrey by one run.
