It is shown that the Łojasiewicz exponent at infinity of a positively defined polynomial of two real variables is attained on the set of zeros of a partial derivative of this polynomial. The second result is that the set of the Łojasiewicz exponents at infinity of positively defined polynomials is equal to the set of rational numbers.
