They will be paid back in the first instance from money generated by season ticket sales.
The season tickets are effectively mortgaged to the debt.
Laxey are charging a higher interest rate than Ticketus did.
The details from the Registers of Scotland (land registry) -

Ranking agreement between Sandy Easdale and Laxey Partners
http://freepdfhosting.com/1bfcbe0abb.pdf
The Ranking Agreement basically establishes that both have claims over both the car park and Edmiston House.
Have a look at the page hand-numbered 19 (its 3 pages down) in the Ranking Agreement - this mentions that the money to Sandy Easdale and Laxey will be repaid in the first instance from season ticket money.
Peculiarly, the announcement to the Stock Exchange said the loan would be repaid by 1st September 2014 - http://www.londonstockexchange.com/exchange/news/market-news/market-news-detail.html?announcementId=11872699 - but the Ranking Agreement says 1st September 2015.
