(a) Bonds, Forms 5120.25 and 5100.12. The surety on a bond given on Form 5120.25 or Form 5100.12 will be relieved from his liability under the bond when the bond has been canceled as provided for in § 28.70.

(b) Bonds, Forms 5100.30 and 5110.67. Where the surety on a bond given on Form 5100.30 or Form 5110.67 has filed application for relief from liability, as provided in § 28.72, the surety will be relieved from liability for withdrawals made wholly subsequent to the date specified in the notice, or on the effective date of a superseding bond, if one is given.
