THIS STATEMENT OF WORK NO. 1 (this "Statement of Work"), effective as of
September 21, 2001 (the "SOW Effective Date"), is entered into by and between
Triton PCS Equipment Company L.L.C. ("Triton") and Ericsson Inc. ("Ericsson")
(each individually referred to as a "Party" and collectively referred to as the

1.       Term. The term of this Statement of Work will commence on the SOW
         Effective Date and will thereafter continue for a period of one (1)
         year. Upon expiration of such 1-year initial term, this Statement of
         Work will be automatically extended for successive two-year periods
         unless either Party provides to the other Party a written notice of
         termination no less than sixty (60) days prior to the expiration of the
         then existing term of this Statement of Work.

2.       Scope of Project. In accordance with the terms and subject to the
         conditions of this Statement of Work, Ericsson will provide to Triton,
         and Triton will obtain from Ericsson, ***** a pilot GSM/GPRS system
         (the "Pilot System"), consisting of *****. The Pilot System is
         specifically described in Attachment A hereto. The Parties anticipate
         that the Pilot System will be launched in December of 2001 in the
         Richmond/Fredericksburg, Virginia market. Triton may use the Pilot
         System for commercial purposes and to determine the feasibility of its
         GSM/GPRS/EDGE/UMTS network.

3.       Assumptions. The scope of the project under this Statement of Work is
         based on the following assumptions:

         (1) *****

         (2) All the GSM sites will be co-located with Ericsson TDMA equipment.

         If and to the extent that these assumptions are invalid, the Parties
         will work together in good faith and mutually agree in writing to
         revise the scope of the project under this Statement of Work. No
         charges shall be payable by Triton to Ericsson on account of any
         revision to the scope of the project unless such revision is deemed by
         the Parties to constitute a material revision and the Parties mutually
         agree on the charges therefor. Any additional charge to be paid by
         Triton to Ericsson as a result of any material revision of the scope of
         the project under this Statement of Work shall be subject to the
         parties' mutual agreement in writing.

4.       Build Out Plan. In accordance with the provisions of the Master
         Purchase Agreement, the Parties will work together in good faith to
         mutually agree upon the Build Out Plan for the build out of the Pilot
         System.

         then existing term of this Statement of Work.

2.       Scope of Project. The scope of the project under this Statement of Work

                  Unless otherwise mutually agreed in writing by the parties,
                  each of the ***** sites will be of one of the types and

                  doubt, Ericsson will provide Triton with the Products and

8.       Interoperability. It is the parties' intent and expectation that the
         Products provided by Ericsson to Triton hereunder will conform to the
         applicable industry standards for GSM and GPRS (the "Standards") and
         will interoperate with third-party products used by Triton in its
         GSM/GPRS/EDGE/UMTS network that conform to the Standards. In the event
         that during the term of this Statement of Work, any Product provided by
         Ericsson to Triton hereunder fails to interoperate with any such
         third-party product as a result of such Ericsson Product's failure to
         conform to the Standards, Ericsson and Triton will work together in
         good faith to resolve any such interoperability issue, which resolution
         may include, without limitation, Ericsson's provision of an interface
         to Triton to enable the Ericsson Product to interoperate with such
         third-party product, at no additional charge to Triton.

IN WITNESS WHEREOF, the Parties by their duly authorized representatives have
executed this Statement of Work as of the SOW Effective Date.
