TRX sold its ResX self-booking tool to nuTravel Technology Solutions for $3.5 million,

the companies announced. As part of the deal, nuTravel acquired "software, websites, certain customer agreements and intellectual property" related to the booking tool, according to a TRX Securities and Exchange Commission filing released on Monday. TRX received $2.6 million upon closing and will gain an additional $0.9 million "subject to the conversion of certain nonassignable contracts to nuTravel." TRX could net even more from the deal as it provides "certain transition and technical services at an annualized rate of $1.8 million." TRX expects that transition to be completed by Dec. 31, 2012.
