Scunthorpe United have been told they must pay £275,000 for Northern Ireland's most recent international recruit, Martin Paterson.
That fee could eventually rise close to £1million, but that depends on Paterson making it to the Premier League with the Irons.
The striker moved from home town club Stoke City to their Championship rivals in the summer, but as he is still under 24-yers-old he wasn't entitled to a free transfer.
With the clubs failing to agree on a price at the time it was down to a tribunal to decide the fee and as well as the initial down payment Stoke will receive further money as Paterson's career goes on.
There will be £30,000 for every 15 appearances until he plays 75 games, making a total of £150,000 and if Scunthorpe win promotion to the English top flight a further £250,000 will be wheeling its way to Paterson's former club.
The 20-year-old has already played 17 times this season, so the first instalment of the pay-for-play is now due, meaning that Scunthorpe owe Stoke £305,000.
In that time he has netted eight goals and his scoring record earned him his Northern Ireland debut in last month's final Euro 2008 qualifier away to Spain.
Stoke will also receive 20 per cent of any future transfer fee that Scunthorpe may receive if Paterson moves.
