(b) the interest was issued by the trust, at or before that time, to an entity, in exchange for consideration and the fair market value, at the time at which the interest was issued, of that consideration was equal to the fair market value, at the time at which it was issued, of the interest;
(c) the only manner in which any part of the interest may cease to be the entity’s is by way of a disposition (determined without reference to section 7.2 and subparagraph e of the second paragraph of section 248) by the entity of that part; and
(d) no amount of the income or capital of the trust that an entity may receive directly from the trust at any time as a beneficiary under the trust depends on the exercise by an entity of, or the failure by an entity to exercise, a discretionary power;
