(a) At a minimum, the trust shall offer contracts of the two types set forth in paragraphs (1) and (2) of this subsection, to be known as Plan A and Plan B, respectively.

(1) Under Plan A:

(A) A payment or series of installment payments of not less than $50.00 per month shall be required from the purchaser on behalf of a qualified beneficiary.

(B) If an advance tuition payment contract is terminated before a qualified beneficiary earns a high school diploma or reaches the age of majority, or pursuant to paragraph (4) of subsection (a) of Code Section 20-3-607, the trust shall refund the face amount of the payment or payments in accordance with the terms of the contract, less any administrative fee specified in the contract, but shall not refund any investment income attributable to the payments.

(C) Except as provided in subparagraph (D) of this paragraph, the trust shall provide for the qualified beneficiary to attend a state institution of higher education at which the qualified beneficiary attends for the number of credit hours required by the institution for the awarding of a baccalaureate degree, without further tuition cost to the qualified beneficiary, except as provided in subsection (a) of Code Section 20-3-605 for a qualified beneficiary who is not entitled to in-state tuition rates.

(D) As an alternative to subparagraph (C) of this paragraph, the trust shall provide for the qualified beneficiary to attend a state institution of higher education at which the qualified beneficiary attends for a fixed number of credit hours, as permitted by the trust, less than the total number of credit hours required by the institution for the awarding of a baccalaureate degree, without further tuition cost to the qualified beneficiary for that fixed number of credit hours, except as provided in subsection (a) of Code Section 20-3-605 for a qualified beneficiary who is not entitled to in-state tuition rates.

(2) Under Plan B:

(A) A payment or series of installment payments of not less than $50.00 per month shall be required on behalf of a qualified beneficiary.

(B) If an advance tuition payment contract is terminated before a qualified beneficiary earns a high school diploma or reaches the age of majority, or pursuant to paragraph (4) of subsection (a) of Code Section 20-3-607, the trust shall refund the face amount of the payment or payments in accordance with the terms of the contract, less any administrative fee specified in the contract, together with all or a specified portion of accrued investment income attributable to the payment or payments as may be agreed to in the contract.

(C) Except as provided in subparagraph (D) of this paragraph, the trust shall provide for the qualified beneficiary to attend a state institution of higher education at which the qualified beneficiary attends for the number of credit hours required by the institution for the awarding of a baccalaureate degree, without further tuition cost to the qualified beneficiary, except as provided in subsection (a) of Code Section 20-3-605 for a qualified beneficiary who is not entitled to in-state tuition rates.

(D) As an alternative to subparagraph (C) of this paragraph, the trust shall provide for the qualified beneficiary to attend a state institution of higher education at which the qualified beneficiary attends for a fixed number of credit hours, as permitted by the trust, less than the total number of credit hours required by the institution for the awarding of a baccalaureate degree, without further tuition cost to the qualified beneficiary for that fixed number of credit hours, except as provided in subsection (a) of Code Section 20-3-605 for a qualified beneficiary who is not entitled to in-state tuition rates.

(b) Contracts required to be offered by this Code section may require that payment or payments from a purchaser, on behalf of a qualified beneficiary who may attend a state institution of higher education in less than four years after the date the contract is entered into by the purchaser, be based upon attendance at a certain state institution of higher education or at that state institution of higher education with the highest prevailing tuition cost for the number of credit hours covered by the contract.

(c) Contracts required to be offered by this Code section shall be offered with two alternatives. One alternative shall offer advance tuition payment contracts that provide the credit hours of higher education necessary for the granting of a baccalaureate degree at any of the state institutions of higher education. The second alternative shall provide that the number of credit hours of higher education a qualified beneficiary may receive under the contract will be reduced to a percentage of the credit hours required for the granting of a baccalaureate degree at a state institution of higher education, as specified in the contract, if the qualified beneficiary enrolls in a state institution of higher education imposing at the time the qualified beneficiary enrolls an annual tuition rate that is greater than 105 percent of the weighted average annual tuition rate of all state institutions of higher education. This subsection shall not preclude a state institution of higher education at which a qualified beneficiary is entitled to receive less than the minimum number of credit hours required for the granting of a baccalaureate degree from providing that qualified beneficiary, without further tuition charges, the additional credit hours necessary to receive a baccalaureate degree.

(d) If a beneficiary of an advance tuition payment contract with either an alternative one or alternative two designation, as described in subsection (c) of this Code section, attends a community or junior college for two years at the in-state tuition rate, that beneficiary then may attend any state institution of higher education at no additional tuition cost and receive the number of credit hours necessary for the awarding of a baccalaureate degree.
