Summary: We obtain explicit formulas for distributions of extrema of exponentials of time-changed Brownian motions with drift which generalize normal inverse Gaussian processes. The generalization is made by multiplying the normal inverse Gaussian processes by a constant. The results are established with respect to the equivalent martingale measure. As examples of applications, problems of path-dependent option pricing are discussed.
