Actually the increase is faster than exponential. The formula is

m = m0/sqrt(1- v**2 / c**2)

where m is the object's mass, m0 is its rest mass (its mass for speed
0), and v is the object's speed

As the formula shows, when v nears c, the denominator of the equation
becomes very small, and m tends to infinity. In order to accelerate
the object to c, you need to give it an infinite amount of energy.
