(b) Payment of the base fee and award fee shall be made, provided that after payment of 85 percent of the base fee and potential award fee, the Government may withhold further payment of the base fee and award fee until a reserve is set aside in an amount that the Government considers necessary to protect its interest. This reserve shall not exceed 15 percent of the total base fee and potential award fee or $100,000, whichever is less.

(c) In the event of contract termination, either in whole or in part, the amount of award fee available shall represent a pro rata distribution associated with evaluation period activities or events as determined by the Government.

Payment may be made without using a contract modification.
