The following payments or allowances shall not be considered to be amounts received as a scholarship or a fellowship grant for the purpose of section 117:
However, amounts paid or allowed to, or on behalf of, an individual to enable him to pursue studies or research are considered to be amounts received as a scholarship or fellowship grant for the purpose of section 117 if the primary purpose of the studies or research is to further the education and training of the recipient in his individual capacity and the amount provided by the grantor for such purpose does not represent compensation or payment for the services described in subparagraph (1) of this paragraph. Neither the fact that the recipient is required to furnish reports of his progress to the grantor, nor the fact that the results of his studies or research may be of some incidental benefits to the grantor shall, of itself, be considered to destroy the essential character of such amount as a scholarship or fellowship grant.
