The memorable win came at the end of a cup run that saw Harry Williams' band of Ulstermen win it the hard way, claiming the scalps of Toulouse and Stade Francais along the way.
As part of the anniversary celebrations, Ulster's 1999 heroes will be taking to the pitch once more, in an exhibition match to raise money for the rugby charities, the IRFU Charitable Trust and the Wooden Spoon at Shaw's Bridge on Thursday, January 29.
The Heineken Cup winners will be supported by their management team from 1999 including coach Harry Williams.
Their opposition, almost 10 years to the day that they defeated Colomiers, will be a Wooden Spoon Select XV, managed by Willie Anderson and made up of former Ulster players and club players from around the province as well as one or two of our friends from the sports media.
Admission is £5 (adults and children) with all proceeds going to the two rugby charities and refreshments will also be available to purchase from the clubhouse.
Tickets for the game can be purchased now from the Ravenhill Ticket Office or online from the Ulster Rugby website.
