ITEM 4.  PURPOSE OF THE TRANSACTION

         Item 4 is amended and supplemented by the addition of the following
paragraph:

         On October 7, 2001, AT&T Wireless, Merger Sub and TeleCorp II entered
into the Merger Agreement pursuant to which Merger Sub would be merged into
TeleCorp II (the "Merger"), with TeleCorp II surviving as a wholly owned
subsidiary of AT&T Wireless. If completed, all of the outstanding shares of
TeleCorp II Common Stock and preferred stock of TeleCorp II ("TeleCorp II
Preferred Stock" and, together with the Telecorp II Common Stock, the "Telecorp
II Capital Stock"), other than shares held by AT&T Wireless, which shall be
cancelled, will be converted into the right to receive shares of AT&T Wireless
Common Stock or AT&T Wireless Preferred Stock, as set forth in Item 3 above. The
completion of the merger is subject to regulatory approvals and other customary
conditions, including the approval of the holders of 50% or more of the
outstanding voting power of the TeleCorp II Capital Stock.

         Also on October 7, 2001, in connection with the Merger Agreement, AT&T
Wireless entered into agreements (the "Voting Agreements") with certain
stockholders of TeleCorp II beneficially owning in the aggregate more than 50%
of the outstanding voting power of the TeleCorp II Capital Stock pursuant to
which such stockholders have agreed (1) to vote their shares of TeleCorp II
Capital Stock in favor of adoption of the Merger Agreement and against proposals
for certain other transactions and (2) not to transfer their shares of TeleCorp
II Capital Stock prior to the consummation of the Merger with specified
exceptions available for certain stockholders.

         Also on October 7, 2001, TeleCorp II, AT&T Wireless and certain other
stockholders of TeleCorp II entered into Amendment No. 1 to the Stockholders
Agreement (the "Stockholders Agreement Amendment") pursuant to which the
Stockholders Agreement was amended to permit the parties to the Voting
Agreements to enter into the Voting Agreements.

         The foregoing descriptions of the Merger, the Merger Agreement, the
Voting Agreements and the Stockholders Agreement Amendment are qualified in
their entirety by reference to the text of the Merger Agreement and the forms of
the Voting Agreements and the Stockholders Agreement Amendment, which are
attached hereto as Exhibits 2.2, 10.10, 10.11 and 10.12, respectively, and are
incorporated herein by reference.

         The Merger Agreement and the transactions contemplated thereby,
including consummation of the Merger, could result in some or all of the events
referred in items (a) through (j) of Item 4 of Schedule 14D. Except as set forth
above, the Reporting Persons have no present plans or intentions that would
result in any of the matters referred to items (a) through (j) of Item 4 of
Schedule 14D.


ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
TO SECURITIES OF TELECORP II

         The response to Items 3 and 4 of this Amendment No. 5 are hereby
incorporated in this Item 6 by reference.
