(3)  Any person performing services in return for aid or sus-
tenance 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)   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 regularly employed
by said employer within this State shall be construed to be employ-
ment 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 work-
men's compensation insurance coverage under the workmen's com-
pensation or similar laws of such other state, so as to cover such
employee's employment while in this State; provided the extrater-
ritorial provisions 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
working within this State shall be prima facie evidence that such
employer carries such compensation insurance.

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