The deal also sees Ace become the MCC’s insurer.
ACE will benefit from global advertising opportunities throughout the cricket season, plus year-round access the facilities at Lord’s.
The deal will also help further improvements to the ground, including the current £8m plan to refurbish the pavilion.
Said MCC secretary and chief executive Roger Knight: “This new partnership will enable the MCC to achieve its objective of ensuring that Lord's remains world-class, as well as world-famous. It will also ensure that we can continue investing in cricket development projects, for the long-term good of the game.”
The MCC is seeking, with sponsorship agency the Frontiers Group, to recruit up to six Lord's partners. Each firm will come from a different business sector; its annual partnership payment will be a six-figure sum.
The club announced its first Lord's partner agreement - with Deutsche Bank - last month.
