The General Partner will be reimbursed by the Partnership monthly over the following 12-month period. In the event that a Limited Partner redeems Class 1 Units within the 12-month period following the date of purchase, the Partnership’s obligation to reimburse the General Partner will immediately terminate and no further payments shall be made.
