Those peace terms included Russia getting to annex Crimea, stationing troops in Donbas (eastern Ukraine), Ukraine retreating all of their troops, Ukraine being neutral (permanently non-allied). In return, Ukraine would have gotten some guarantor states safekeeping its newly drawn borders (but Russia would have been able to veto any action of those guarantor states in case someone, possibly Russia, attacked the Ukraine again). This seems a bit of a complete joke to me? Can you explain, why, exactly, Ukraine should have taken that offer? This is basically "I give you everything we are currently fighting over, in return I get an absolutely worthless promise from a serial liar". No deal.
