All other conditions and provisions of the conversion right section of the group policy to which this rider is attached will apply. Do any Waiver of Premium, Extended Benefits, or Total and Permanent Disability riders to the group policy apply to insured dependents? Any Waiver of Premium, Extended Benefits or Total and Permanent Disability rider to the group policy will not apply to dependents covered under this rider except as provided for herein. If, due to the insured employee s disability, his or her insurance is continued in force without further payment of premiums due to any Waiver of Premium, Extended Benefits, or Total and Permanent Disability rider to the group policy, any dependents insurance provided by this rider shall also continue in force without further payment of premiums until the dependent s eligibility terminates or until the insured employee s insurance is no longer continued in force due to any such rider to the group policy.
