this is how lawyers make life

basically it tells that releasor will be responsible for any future loss sufferred by the releasee, in the form of either "contribution" (which means the "releasee" might be partically liable to some wrongdoing) or "indemnity" (which means the "releasee" might be totally responsible for some wrongdoing of someone else rather than the releasee).

by this standard "contribution & indemnity" clause, parties to the contract agree that any future general liabilities arising from something under this contract, if any, will be transferred from the releasee to the releasor. i.e. the releasor will be the final responsible party.

as u see, the "loss" is defined very broadly, which may include any attorney fees and court fees.
