(1)    Any person employed as a domestic servant in a private
home by an employer who has less than two such employees regularly
employed 40 or more hours a week in such employment.

(2)    Any person other than those defined under Section 21 (c)
(1) employed for not exceeding 30 consecutive work days, to do
maintenance, repair, remodeling, or similar work in or about the
private home of the employer, or, if the employer has no other
employees subject to this act, in or about the premises where such
employer carries on his trade, business or profession.

(3)    Any person performing services in return for aid or suste-
nance only, received from any religious or charitable organization.

(4)    Any person for whom a rule of liability for injury or death
is provided by the laws of the United States.

(6) (5) Casual employees or any employees who are employed
wholly without the State, except that for all purposes of this article,
casual, occasional or incidental employments outside of this State by
the Maryland employer of an employee or employees regulary em-
ployed by said employer within this State shall be construed to be em-
ployment within this State; provided, however, if an employee or the
dependents of an employee shall receive compensation or damages
under the laws of any other state, nothing herein contained shall be
construed so as to permit a total compensation for the same injury
greater than is provided for in this article.

An employee and his employer who are not residents of this State
and whose contract of hire is entered into in another state shall be
exempted from the provisions of this article while such employee is
temporarily or intermittently within this State doing work for such
nonresident employer, if such employer has furnished workmen's
compensation insurance coverage under the workmen's compensation
or similar laws of such other state, so as to cover such employee's
employment while in this State; provided the extraterritorial pro-
visions of this article are recognized in such other state and provided
employers and employees who are covered in this State are likewise
exempted from the application of the workmen's compensation or
similar laws of such other state. The benefits under the Workmen's
Compensation Act or similar laws of such other state shall be the
exclusive remedy against such employer for any injury, whether
resulting in death or not, received by such employee while working
for such employer in this State.

A certificate from the duly authorized officer of the industrial
accident commission or similar department of another state certify-
ing that the employer of such other state is insured therein and has
provided extraterritorial coverage insuring his employees while work-
ing within this State shall be prima facie evidence that such employer
carries such compensation insurance.

members of boards or commissions, volunteer workers for agencies or
departments of any political subdivisions, volunteer civil defense
members of OR trainees, members of volunteer fire departments and
