Equation (2) is incorrect as published. It should instead be rendered as follows:

$$ {l}_x^e= \exp \left(-\frac{\uplambda \upbeta}{r} \exp \left(-1/\upbeta \right)\left( \exp \left(rx/\upbeta \right)-1\right)+\upalpha \upgamma \exp \left(-x/\upalpha \right)\right) $$

This correction does not affect any of the analysis or conclusions of the article.
