Barclays and Citi were co-ordinators on the amend and extend procedure.
The loan initially had a three year tenor and was due to mature in June 2016. It is now due in June 2018.
Furthermore, Unatrac has negotiated a cut in margin from 400bp to 275bp over Libor.
All the lenders on the initial deal agreed to the new terms. Two new banks joined the deal at a junior level: National Bank of Abu Dhabi and Commercial Bank of Abu Dhabi.
The rest of the bank group comprised mandated lead arrangers Barclays, Citi, JP Morgan, Caterpillar Financial Services, Commercial International Bank, HSBC, Mashreqbank, Qatar National Bank Group and Standard Bank.
First Gulf Bank and Standard Chartered resumed their roles as lead arrangers. Commercial Bank of Dubai and Ahli United also participated.
Borrowers have been benefiting from low margins in the last two years to either refinance debt early or amend and extend existing facilities.
Indeed, 2014's refinancing facilities account for a record share of global syndicated loan volumes, according to Dealogic data released on Monday.
This year, refinancing deals make up 62%, or $1.26tr, of the global syndicated loan market. That is up from 51% this time last year.
