Reimbursement may be awarded in a lump sum or in installments in the discretion of the board. The amount of any emergency award shall be deducted from the final award, if a lump sum, or prorated over a period of time if the final award is made in installments. Reimbursement is exempt from execution or attachment except by persons who have supplied services, products or accommodations to the victim as a result of the injury or death which is the basis of the claim. The board, in its discretion may order that all or part of the reimbursement awarded be paid directly to these suppliers.
