               amount that yields the same amount of gross proceeds to TeleCorp
               PCS, Inc. as the Company would have received from the issuance of
               the requested Expansion Notes."

               iii.  Section 28 of Note Purchase Agreement is hereby amended by
               deleting the following provision:

               $198,000,000 multiplied by (Y) a fraction the numerator of which
               is the sum of (A) 16,800,000 plus (B) the number of POPs in
               Expansion Areas for which Expansion Notes have been or concurrent
               therewith are being issued and the denominator of which is
               16,800,000; and
