Method of moments for a transformed Bernoulli

Let $0,1,0,0,1$ be the observed values of a random sample of size five from a discrete distribution with the probability mass function $P(X=1)=1-P(X=0)=1-e^{-\lambda}$, where $\lambda>0$. The method of moments estimate (round off to 2 decimal places) of $\lambda$ equals __________
