ORS § 461.310
Upon recommendation of the Director of the Oregon State Lottery, the commission shall determine the compensation to be paid to lottery game retailers for their sales of lottery tickets or shares. Until the commission shall otherwise determine, the compensation paid to lottery game retailers shall be five percent of the retail price of the tickets or shares plus an incentive bonus of one percent based on attainment of sales volume or other objectives specified by the director for each lottery game. In cases of a lottery game retailer whose rental payments for premises are contractually computed in whole or in part, on the basis of a percentage of retail sales, and where such computation of retail sales is not explicitly defined to include sales of tickets or shares in a state-operated lottery, the compensation received by the lottery game retailer from the Oregon State Lottery shall be deemed to be the amount of the retail sale for the purposes of such contractual computation.
