(a) The initial amount of insured indebtedness to which the rate is applied shall not exceed the aggregate of the periodic scheduled unpaid installments of the indebtedness.

(b) The indebtedness is repayable in substantially equal monthly installments during the period of coverage.

(c) The rates for premiums payable on other than a single premium basis shall be the actuarial equivalent of the rates set forth in Section 6 hereof. Such premium rates will be deemed the actuarial equivalent of the foregoing single premium rates if such rates produce a total premium for any duration and amount of insurance equal to the corresponding single premium for the same duration and amount of insurance.

(d) The credit disability insurance contract does not cover disabilities resulting from pre existing illness, disease or physical condition and may require submission of evidence of insurability and that the debtor be in gainful employment at the time the insurance becomes effective and contains no exclusions other than disability resulting from normal pregnancy, intentionally self inflicted injuries, foreign travel or residence, flight in non scheduled aircraft, war or military service. The eligibility for disability coverage may be restricted on account of age in the same manner as permitted for credit life insurance in Section 5.2(b) hereof.
