b. The minimum of 5 minutes is maintained between the preceding and following aircraft; and

c. The following aircraft is separated by not more than 4,000 feet from the preceding aircraft when the climb clearance is issued; and

d. The following aircraft commences climb within 10 minutes after passing:

1. An exact reporting point (DME fix or intersection formed from NAVAID's) which the preceding aircraft has reported; or
