Abstract: A valuation framework for extendible options is constructed when the underlying asset obeys a fractional process with jump. Under the risk neutral environment, an analytic formula for the call option with one extendible maturity is derived by solving the expected present value of cashflow and conditioning jumps for the underlying asset. Moreover, some special cases of the formula are discussed. These results are generalized to the option with$ M $extendible maturity. Its value will converge in the limit to the value of perpetual extendible option as the number of extendible maturity increases to infinite. Extrapolated technique with two
points is presented to yield a simple and efficient computation procedure to calculate the limit. Numerical results are provided to illustrate provided that our pricing expressions are easy to implement.

Key words: jump fraction process, extendible option, extrapolated technique with two points
