     RE:   POWERTEL USA, INC. FORMERLY KNOWN AS NEVADA ENERGY COMPANY, INC.
           FORMERLY KNOWN AS MUNSON GEO THERMAL, INC.

Dear Mr. Troutner:

         As we discussed this evening, this firm is legal counsel to PowerTel
USA, Inc., (F/K/A Nevada Energy Co.) (the "Company"), whose Class A Common
Shares are traded in the over-the-counter market. As I advised you earlier
today, effective 5:00 p.m. (EST) today, the company is requesting that trading
in its Class A Common Shares be halted in order that the company can implement
certain provisions of the Plan of Reorganization as approved by the United
States Bankruptcy Court for the District of Nevada and NASD Rules.

         In this context, in or about February, 1997, an Involuntary Petition
for Reorganization was filed by three creditors. Thereafter, an interim Trustee
was appointed. In or about October, 1997, the United States Bankruptcy Court,
with the concurrence of the Trustee, approved a petition authorizing the Company
to resume operations functioning as Debtor-in-Possession pursuant to Section
1107 of the United States Bankruptcy Code. Thereafter, the Company prepared a
proposed Plan of Reorganization and the Bankruptcy Court approved for
dissemination to creditors and shareholders a Disclosure Statement, pursuant to
the United States Bankruptcy Code.

         In August, 1998, United States Bankruptcy Court held a hearing for the
purpose of receiving a report with respect to the votes of creditors and
shareholders regarding the proposed plan. Thereafter, on or about September 24,
1998, the United States Bankruptcy Court confirmed the Plan of Reorganization as
submitted by the Company.

         The Plan, as approved by the Court, requires that the Company take
certain action with respect to the recapitalization of the equity as it relates
to the issued outstanding Shares of the

Company sheet. Among other things, the Plan voids all shares of Class A Common
Stock issued by the Company subsequent to May 3, 1996 unless (1) the shareholder
files a Proof of Interest with the United States Bankruptcy Court establishing
that the shareholder was a bona fide shares purchaser for value, and (2) the
debtor does not file an objection to the Proof of Interest or, if such an
objection is filed, the Court determines that the Proof of Interest is valid.

         In addition, a 1:6 reverse stock split effected in or about January,
1997 is rescinded. Other significant events include the conversion of Class B
Common Shares into Class A Common Shares, and the issuance of a large block of
Class A Common Shares to 16 Bahamian corporations which collectively will own
50% of the issued and outstanding Class A Common Shares after issuance, subject
to a further adjustment to be effective ten (10) days after the Effective Date
of the Plan. In addition, the company has effected an acquisition which could
result in the transfer of up to 35% of issued and outstanding Class A Common
Shares to a third party.

         The Company is requesting a halt in the trading of its Class A Common
Shares in order that the Company can file Amended Articles of Incorporation,
rescind a previous 1:6 reverse stock split, ascertain the identity of
shareholders of record and issue to such individuals and entities new stock
certificates pursuant to the Plan.

         At this time, we estimate that 2-4 weeks will be required to complete
this process. When all of the events mandated by the Plan of Reorganization have
been implemented, we will advise the NASDAQ in order that trading may be
resumed.

         Thank you for your cooperation and assistance. in the event that you
have any questions or comments, do not hesitate to call the undersigned.

                                        Sincerely,

                                        /s/ Van P. Carter

                                        Van P. Carter
