                  DEBTOR'S FIRST AMENDED PLAN OF REORGANIZATION

         PowerTel USA, Inc. (generally referred to as "Debtor" but sometimes
referred to as "PowerTel"), a Delaware corporation, currently operating as
Debtor-in-Possession pursuant to 11 U.S.C. Section 1107 of the United States
Bankruptcy Code (the "Bankruptcy Code"), does hereby propose the following
DEBTOR'S FIRST AMENDED PLAN OF REORGANIZATION ("Plan") for the resolution of
Debtor's outstanding Allowed Claims and Equity Interests.

         NOTE: Capitalized terms are defined in Article 11 of this Plan.
<PAGE>   2
ARTICLE I:  INTRODUCTION

         Debtor is a Delaware corporation established in 1983. When
incorporated, the Debtor was known as Munson Geothermal, Inc. ("Munson"). In May
1988, Munson (together with its wholly owned subsidiary) filed a Petition for
Reorganization pursuant to Chapter 11 of the Bankruptcy Code (the "Munson
Reorganization"). The Munson Reorganization resulted in the confirmation of a
FIRST AMENDED PLAN OF REORGANIZATION submitted by Mr. Jeffrey Antisdel and Hot
Springs Power Company. The Plan was confirmed in or about November 1990, and the
Debtor's name was changed to Nevada Energy Company, Inc. ("Debtor").

         From November 1990 through May 1996, Debtor conducted business under
the leadership of Mr. Antisdel. As of May 1996, Debtor existed as a publicly
traded company current with respect to all filings required to be made with the
Securities and Exchange Commission ("SEC") pursuant to the Securities Exchange
Act of 1934 ("Exchange Act"). In addition, Debtor was financially solvent with
net assets in excess of $4,000,000 and was intermittently profitable. In March
1996, Debtor entered into an agreement to sell preferred shares to Waterford
Trust Company, Ltd. As part of that transaction, the Shareholders and Directors
of Debtor consented to a change of control. As a result, in May 1996, the Board
of Directors of Debtor resigned and was replaced by Directors designated by
Waterford's nominee, Golden Chance, Ltd.

         From May 1996 through February 13, 1997 (the day of the commencement of
this proceeding), the financial affairs of Debtor declined significantly. Among
other things, the Debtor Board, aided and abetted by various third parties,
entered into a series of contracts and transactions which dissipated corporate
assets; revenue declined significantly; the Company was unable to pay its debts
as they became due; and the Company failed to file reports mandated by the
Exchange Act.
<PAGE>   3
There was even an attempt to amend the Debtor's Articles of Incorporation
without securing requisite shareholder approval.

         As a consequence of this decline in Debtor's financial condition,
pursuant to section 303 of the Bankruptcy Code, on February 13, 1997, multiple
creditors initiated a legal proceeding to cause the Debtor to be involuntarily
reorganized pursuant to Chapter 11 of the Bankruptcy Code. As a result of the
forced reorganization, the following events occurred:

         1. On or about March 3, 1997, the Court appointed an interim Trustee to
administer the affairs of the Debtor.

         2. There was a change of control with respect to the Debtor's Board of
Directors, and new management was elected.

         3. On or about September 24, 1997, the Court authorized the Debtor to
function as a Debtor-in-Possession pursuant to section 1107 of the Bankruptcy
Code.

         This FIRST AMENDED PLAN OF REORGANIZATION is submitted by the Debtor
and is intended to constitute a full and final resolution of Debtor's Allowed
Claims and Equity Interests. Each Claim and Equity Interest will be allocated
into one of ten separate Classes. Eight of the Classes will be for Allowed
Claims, four of which will be Impaired. One Class will be for Disputed Claims.
One Class will be for Equity Interests.

         In developing this Plan, the Board of Directors of Debtor examined the
affairs of Debtor and its predecessor-in-name - Debtor. Based upon that
examination, the Board has concluded that Debtor must develop a new business
plan and this business plan should seek to develop the telecommunications
business opportunities initially brought to Debtor through its acquisition of
<PAGE>   4
Telecom Technologies, Inc. ("TTI") in August 1996. Debtor also plans to continue
exploring business opportunities or its cogeneration assets.

         In designing its business plan, the Board took into consideration
various factors including, but not limited to, the substantial equity position
held by Nevada Energy Partners I, a Nevada limited partnership ("NEP") (which is
equal to 50.0% of the issued and outstanding Class A Common Stock of Debtor) and
the potential impact of the claim of $6,000,000 lodged by NEP upon the estate of
Debtor.

         In negotiating with NEP and others, Debtor was not in a position of
economic strength and, therefore, some of the negotiations may not have been
conducted on an arm's length basis.

         Nevertheless, on balance, taking all factors into consideration,
Debtor's Board has determined that the Plan, as presented, is reasonable and
fair and, in the business judgment of the Board, represents the best opportunity
for Debtor's Creditors and shareholders to recoup their investment.

         The Plan is predicated upon several events transpiring as anticipated,
including (but not limited to) the following:

         1.       Successful implementation of the Debtor's new Business Plan,
                  which anticipates that the Debtor will shift emphasis from
                  energy co-generation to telecommunications. As part of this
                  new Business Plan, the Debtor anticipates that it may issue up
                  to 35.0% of its Class A Common Stock to one individual in
                  conjunction with a start-up telecommunications company;

         2.       Execution of the Settlement and Release Agreement by all
                  Parties to that Agreement, including the Debtor, NEP, Nevada
                  Electric Power Company and others (the "NEP Settlement");
<PAGE>   5
         3.       Ratification of the NEP Settlement by the Bankruptcy Court;

         4.       Confirmation of this Plan as submitted;

         5.       Utilization of the Debtor's cogeneration assets as collateral
                  for Letters of Credit or otherwise securing working capital to
                  fund or secure payment of the Debtor's current and future
                  business operations, especially the telecommunication
                  business;

         6.       Preparation and filing of all reports required to be filed
                  pursuant to the Exchange Act;

         7.       Approval of an application to be filed by the Debtor with the
                  National Association of Securities Dealers, Inc. ("NASD")
                  relisting the Debtor's Class A Common Stock as a "small cap"
                  security;

         8.       The resumption of an active secondary market through the NASD
                  for the Debtor's Class A Common Stock; and

         9.       The recision of all Common and Preferred Stock allegedly
                  issued subsequent to May 3, 1996 by Debtor and recision of the
                  1:6 reverse stock split attempted in January 1997.

         Should any one or more of these events not transpire, DEBTOR'S FIRST
AMENDED PLAN OF REORGANIZATION will have to be reconsidered and, perhaps,
revised and amended. There is, of course, no assurance or guaranty that any one
or all of the above events will transpire as desired.

         As a result of events 1 and 2 above, the Debtor will issue Class A
Common Stock to a total of 16 persons or entities in an amount equal to 50.0% of
the issued and outstanding Class A Common Stock on the Effective Date. An
additional 35.0% of the Class A Common Stock may be
<PAGE>   6
issued pursuant to the Diego Tel share exchange agreement. These events may have
long term implications for the remaining shareholders.

                                         Stock to be issued.

                                         Date.

                                  F    = Dollar amount of funds allocated for
                                         purchase of Class A Common Stock.

                                  AVP  = An average of the closing price per
                                         share of Class A Common Stock for the

ARTICLE XI.   FOR PAYMENT OF CLAIMS OF NEVADA ENERGY PARTNERS, LTD., NEVADA
              ELECTRIC POWER COMPANY AND OTHERS (CLASS 8)

         11.1 NEP, Nevada Energy Power Company ("NEPC"), the Debtor and others
have entered into a Settlement and Release Agreement ("NEP Settlement") pursuant
to the terms of which the following will transpire:

              A.   Subject to approval of the Bankruptcy Court and confirmation
                   of this Plan, the NEP Agreement between NEP and amended and
                   restated. As a result of this rescission of conveyances, the
                   Debtor shall receive 100% of the issued and outstanding
                   Common Stock of Combustion Energy Company and title to a
                   parcel of real property situated in Reno, Nevada.

              B.   Debtor will stipulate that NEP shall be deemed to be the
                   shareholder of record of 13,245,958 shares of Class B Common
                   Stock, which is convertible into 13,245,958 shares of Class A
                   Common Stock as of August 16, 1996.
<PAGE>   20
                   NEP, as of December 1, 1997, will be deemed to have converted
                   Class B Common Stock into Class A Common Stock such that NEP
                   owns 13,245,958 shares of Class A Common Stock which is equal
                   to 50.0% of the issued and outstanding Class A Common Stock
                   of Debtor as of August 16, 1996.

              C.   Debtor will stipulate that the Class A Common Stock held of
                   record by NEP is beneficially owned by sixteen (16) separate
                   corporations who are also deemed to be Creditors of the
                   Debtor.

              D.   Debtor will agree to permit the transfer of the Class A
                   Common Stock from NEP to the sixteen (16) beneficial owners
                   and will stipulate that these sixteen corporate entities
                   shall be issued (if Debtor) additional Class A Common Stock
                   such that they own 50.0% of the issued and outstanding Class
                   A Common Stock of Power Tel computed as of ten (10) business
                   days after the Effective Date, which will be subsequent to
                   the reverse stock split to be effected by the Debtor pursuant
                   to this Plan, subsequent to the issuance of Class A Common
                   Stock to Creditors pursuant to this Plan, and subsequent to
                   the issuance of Class A Common Stock to acquire Diego Tel. In
                   the event, however, that Creditors with a Disputed Claim
                   receive Class A Common Stock pursuant to the Disputed Claims
                   Reserve, there will not be any additional distributions of
                   Class A Common Stock pursuant to the NEP Settlement.

              E.   The limited partnership agreement for NEP is deemed to be
                   amended and modified such that 99.0% of all profits and
                   losses are allocated to the capital account of the limited
                   partner effective as of January 1, 1995. The general partner
                   (NEPC) will stipulate that Debtor is the sole limited
                   partner. Any and all distributions of cash and property are
                   to be allocated 60.0% to the limited partner and 40.0% to the
                   general partner.

              F.   All parties to the NEP Settlement do forever settle, release
                   and compromise all claims and causes of action which they
                   have or may bring against any other party as of the date of
                   that Agreement, and NEP specifically waives and commits to
                   extinguish its Proof of Claim for $6,000,000.00.

ARTICLE XII.  PROVISIONS FOR ADJUDICATION OF DISPUTED CLAIMS (CLASS 9)

         12.1 The Debtor has disputed certain Claims submitted by various
alleged Creditors. If and when any such disputed Claim becomes an Allowed Claim
or Equity Interest, such Allowed
<PAGE>   21
Claim or Equity Interest shall be treated as if it was an Allowed Claim or
Equity Interest with respect to the classification of Claims and Equity Interest
provided in Article III of this Plan.

ARTICLE XIII. PROVISIONS FOR TREATMENT OF ALLOWED EQUITY INTEREST (CLASS 10)

         13.1 Upon Confirmation of the Plan, the Debtor will initiate various
actions which will affect the Equity Interests of Shareholder who own either (a)
Class A or Class B Common Stock, or (b) Series A, Series B or Series C Preferred
Stock.

         13.2 It is the Debtor's position that certain actions taken by the
Board of Directors of Debtor subsequent to May 3, 1996 and prior to February 13,
1997 are void, illegal and/or invalid including, but not limited to, all offers
and sales of Common or Preferred Shares of Debtor. Accordingly, all Common and
Preferred Shares of Debtor issued subsequent to May 3, 1996 are deemed to be
void ab initio except as to any Shareholder who (i) is a bona fide purchaser for
value, and (ii) filed a Proof of Interest on or before November 10, 1997, which
Proof of Interest has not been disputed by the Debtor. In addition, the
attempted 1:6 reverse stock split purportedly implemented by the Debtor Board of
Directors in January 1997 is also void ab initio. It is the express intent of
this Plan to reinstate all Class A Common Stockholders of record to the same
share ownership which existed as of May 3, 1996 immediately prior to the sale of
the Series A Preferred Shares to Waterford/Golden Chance.

         13.3 After the Confirmation Date, the Debtor shall effect the actions
set forth in Article XIX of this plan. As a consequence of such events, the
following shall occur:

              A.   The Series A and Series C Preferred Shares and the Class B
                   Common Stock shall be deemed to be extinguished through
                   amendment to the Debtor's Articles of Incorporation (Series B
                   Preferred and the Class B Common Stock
<PAGE>   22
                   will also be extinguished through amendment following the
                   actions described below).

              B.   The five (5) shares of Series B Preferred Shares owned by
                   Messrs. Rick Cascarilla (2 shares), Jeff Hartman, Michael
                   Kassouff and Jeff Modesitt (all former Directors of Debtor
                   who acquired the Series B as part of the May 1996 transaction
                   with Waterford/Golden Chance) shall be repurchased by the
                   Debtor for a per share price of (i) 100,000 shares of Class A
                   Common Stock; and (ii) a 24 month option to purchase an
                   additional 100,000 shares of Class A Common Stock at an
                   exercise price of $0.10 per share. The Series B Preferred
                   Shares thereafter shall be extinguished by means of an
                   amendment to the Articles of Incorporation, which amendment,
                   among other things, shall establish a new class of preferred
                   shares to be known as "Special Stock." The Special Stock has
                   the right to elect two (2) Directors of the Debtor's Board of
                   Directors. One share each of Special Stock, as set forth in
                   the amended Articles of Incorporation, shall be issued to
                   Richard Cascarilla, Jeffrey Hartman and Michael Kassouff as
                   partial consideration for their serving on the Board of
                   Directors. The Articles of Incorporation and By-Laws will be
                   amended so that the Board will be authorized to set
                   additional terms of the Special Stock.

              C.   All holders of Class A Common Stock will be reinstated to the
                   exact same share ownership which existed as of May 3, 1996,
                   immediately prior to the sale of the Series A Preferred
                   Shares to Waterford/Golden Chance.

              D.   The Debtor will convert the Class B Common Stock to Class A
                   Common Stock pursuant to the NEP Settlement (see Article XI
                   of this Plan) and will issue Class A Common Stock in an
                   amount equal to 50.0% of the outstanding Class A Common Stock
                   pursuant to the NEP Settlement.

              E.   Debtor will affect a reverse stock split at a ratio to be
                   designated by the Board of Directors such that the total
                   number of shares of Class A Common Stock outstanding
                   subsequent to the reverse stock split is no less than 500,00
                   shares nor more than 20,000,000 shares.

                   Subsequent to the reverse stock split and the issuance of
                   Class A Common Stock to creditors, the Debtor will adjust the
                   number of shares of Class A Common Stock issued per the NEP
                   settlement to maintain that figure at 50.0% of the issued and
                   outstanding Class A.

                   Up to a maximum of 35.0% of additional shares of Class A
                   Common Stock may be issued in conjunction with the
                   acquisition of Diego Tel.
<PAGE>   23
         13.4 Reorganization of Class A Common Stock. In addition to consenting
to the transfer of Class A Common Stock from NEP to the sixteen entities as set
forth in Section 11.2, Debtor anticipates that it may issue additional shares of
Class A Common Stock in conjunction with its acquisition of Diego Tel. At this
time, based upon current negotiations, the Debtor anticipates that it may issue
Class A Common Stock equal to 35.0% of the issued and outstanding Class A Common
Stock. The Class A Common Stock will be issued by the Debtor once certain
revenue projections are satisfied. The Debtor and Mr. Wallace have executed an
Agreement which has been amended and restated. The amended Agreement will be
filed with the Court and ratified as part of the Plan.

ARTICLE XIV.  PROVISIONS FOR TREATMENT OF DISPUTED CLAIMS

         14.1 Authority to Object. The Debtor and any party-in-interest shall
have the authority to object to and contest the allowance of any Claim filed
with the Bankruptcy Court in respect of any Claim listed as disputed,
contingent, or unliquidated on the Debtor's schedules, except as to any Claim
otherwise treated by the Plan or previously allowed or disallowed by final order
of the Bankruptcy Court.

         14.2 Objections to Claims to be Filed Within Sixty Days After
Confirmation Date. Unless otherwise ordered by the Court, after notice and a
hearing, objections to Claims and Equity Interests shall be made and filed by
the Debtor or by any party-in-interest and shall be served upon each holder of
the Claim or Equity Interest to which objections are made (and upon the Debtor's
attorney if the Debtor is not the objecting party) and filed with the Bankruptcy
Court as soon as practicable, but in no event later than sixty (60) days
subsequent to the Confirmation Date.
<PAGE>   24
         14.3 Prosecution of Objections to Claims.

              A.   The objecting party shall litigate to judgment, settle, or
                   withdraw objections to Disputed Claims.

              B.   All legal fees and expenses of the Debtor incurred in the
                   prosecution of claim objections and in the consummation of
                   the Plan shall be paid first by the Debtor as a
                   Post-Confirmation Administrative Expense pursuant to Article
                   4.2 of this Plan.

         14.4 Final Order. Except as may be otherwise agreed with respect to any
Disputed Claim, no payments or Distributions shall be made with respect to all
or any portion of a Disputed Claim unless and until all objections to such
Disputed Claim have been determined by a Final Order of the Bankruptcy Court.
Payments and Distributions to each holder of a Disputed Claim or Disputed Equity
Interest to the extent that it ultimately becomes an Allowed Claim or Allowed
Equity Interest shall be made in accordance with the provisions of the Plan with
respect to the Class of Creditors or Equity Interest to which the respective
holder of an Allowed Claim or Allowed Equity Interest belongs, unless otherwise
provided in Section 14.5 herein below.

         14.5 Disputed Claims Reserve.

              A.   In determining the amount of Distributions due the holders of
                   Allowed Claims, the appropriate Pro Rata calculations
                   required by the Plan shall be made as if all Disputed Claims
                   were Allowed Claims in the full amount claimed by the holders
                   thereof. Debtor will presume, for purposes of the Disputed
                   Claims Reserve, that all Disputed Claim Creditors elect to
                   receive Class A Common Stock.

              B.   On the Effective Date, the Debtor shall compute the number of
                   shares of Class A Common Stock to which the Disputed Claim
                   Creditors may be entitled and shall disburse such shares
                   (hereinafter the "Disputed Claims Reserve") to be held in
                   trust by the Debtor for the benefit of the holders of Allowed
                   Claims whose Distributions are unclaimed and the holders of
                   Disputed Claims pending determination of their entitlement
                   thereto under the terms of the Plan. The Class A Common Stock
                   held in the Disputed Claims Reserve shall be deemed to be
                   "treasury" stock of the Debtor and thus non-
<PAGE>   25
                   voting during the period within which it is held in the
                   Disputed Claims Reserve.

              C.   As soon as practicable after a Disputed Claim becomes an
                   Allowed Claim, the Class A Common Stock reserved for such
                   Allowed Claim shall be released by the Debtor from the
                   Disputed Claims Reserve and delivered to the holder of such
                   Allowed Claim. In the event that the Disputed Claim is
                   disallowed, the Class A Common Stock provided for such claim
                   shall be released to Debtor for use in the course of its
                   business, as deemed appropriate by its Board of Directors.

                   In the event that a Disputed Claim becomes an Allowed Claim
                   and the Creditor is entitled to receive Cash, the Debtor
                   shall pay such Cash upon the later of (i) the Payment Date,
                   or (ii) ninety (90) days after the Disputed Claim becomes an
                   Allowed Claim.

              D.   In the event any Class A Common Stock held in the Disputed
                   Claims Reserve remain unclaimed upon expiration of five years
                   following the Effective Date, such Class A Common Stock shall
                   be released to Debtor.

                   If Class A Common Stock is issued pursuant to this Article
                   XIV, such action shall not be a basis for an adjustment with
                   respect to the number of shares of Class A Common Stock
                   issued pursuant to the NEP Settlement or for the acquisition
                   of Diego Tel.

ARTICLE XV.        CRAMDOWN OF PLAN

         15.1 In the event that any one or more classes of impaired Claims does
not approve the Plan by the requisite vote and the Plan is not confirmed, the
Debtor shall seek confirmation of the Plan pursuant to the provisions of section
1129(b) of the Bankruptcy Code. In the event that the Bankruptcy Court refuses
to approve the Plan pursuant to section 1129(b) of the Bankruptcy Code, the NEP
Settlement, the agreement for the acquisition of VivaTel and Diego Tel and the
Ownership Settlement Agreement shall be deemed null and void and the parties
thereto shall be returned to their respective positions, status quo ante.

ARTICLE XVI.  IDENTIFICATION OF CLAIMS AND EQUITY INTEREST NOT IMPAIRED BY THE
              PLAN

         16.1 Unimpaired Classes. Claims of classes 1, 2, 3 and 6 are not
impaired under the Plan.

         16.2 Impaired Classes to Vote on Plan. Claims in the classes specified
in Classes 4, 5, 7 and 8 of the Plan are impaired and therefore Creditors
holding Claims in these classes are entitled to vote whether to accept or reject
the Plan. Voting Shareholders are also entitled to vote.

         16.3 Controversy Concerning Impairment. In the event of a controversy
as to whether any Creditors or holders of Equity Interest or class of Creditors
or class of holders of Equity Interest are impaired under the Plan or otherwise
entitled to vote, the Bankruptcy Court shall, after notice and a hearing,
determine such controversy.

ARTICLE XVII. ACCEPTANCE OR REJECTION OF PLAN: EFFECT OF REJECTION BY ONE OR 
              MORE CLASSES OF CLAIMS

         17.1 Acceptance by Class of Creditors. A Class of Creditors shall have
accepted the Plan if the Plan is accepted by at least 2/3 in amount and more
than 1/2 in number of the Allowed Claims of such class that have voted.

         17.2 Cramdown. In the event that any impaired class of Creditors with
Claims against any of the Debtor's estate shall fail to accept the Plan, in
accordance with section 1129(a) of the Bankruptcy Code, the Debtors shall
request the Bankruptcy Court to confirm the Plan in accordance with section
1129(b) of the Bankruptcy Code.

ARTICLE XVIII. JUDICIAL ACTIONS

         18.1 Promptly after the Confirmation Date, the Bankruptcy Court shall
enter an Order to the effect that:

              A.   All Common and Preferred Stock issued by Debtor subsequent to
                   May 3, 1996 was issued in violation of the Company's Articles
                   of Incorporation or without requisite approval of the Board
                   of Directors and, therefore, is null and void ab initio
                   except as to Shareholders who (i) are bona fide purchasers
                   for value, and (ii) filed a Proof of Interest on or before
                   November 10, 1997, which Proof of Interest was not disputed
                   by the Debtor.

              B.   The election of Michael Kassouff as a Director by the Series
                   B Preferred Shareholders is ratified. The election by Michael
                   Kassouff, as the sole Director, of Messrs. Richard Cascarilla
                   and Lawrence Herth as Directors is ratified. Also ratified
                   are all elections of officers by the Debtor's Board of
                   Directors;

              C.   The 1:6 reverse stock split effected by Debtor in January
                   1997 was conducted without requisite shareholder approval and
                   is null and void ab initio;

              D.   The amendments to Debtor's Articles of Incorporation filed
                   with the Secretary of State for the State of Delaware in
                   January 1997 were not adopted by Debtor's shareholders and,
                   therefore, are null and void ab initio;

              E.   Any claimed security interest of Brady Geothermal Park Power
                   Partners against any assets of Debtor is null and void;

              F.   The following actions taken by the Debtor's Board of
                   Directors are null and void ab initio due to violations of
                   applicable provisions of Delaware law:

                        i.   Proposal to Amend Corporate Name and Symbol,
                        ii.  Proposal to Increase Authorized Shares,

                             Barbara Property;

              G.   Pursuant to section 1123(b)(3) of the Bankruptcy Code, Debtor
                   is authorized to amend, supplement or modify this listing
                   upon further investigation of the corporate records;

                   exclusive right to enforce any and all causes of action
                   against any person in rights of the Debtor that arose before
                   or after the petition date, including but not limited to the
                   rights and powers of a trustee and debtor in possession,
                   against any person whatsoever, including but not limited to
                   all avoidance powers granted to the debtor under the
                   Bankruptcy Code and all causes of actions and remedies
                   granted pursuant to sections 502, 510, 541, 544, 545, 547
                   through 551 and 533 of the Bankruptcy Code.

                   445-53-00 (being a renewal of policy number 443-38-50) and
                   the Debtor is authorized to reserve all rights to pursue any
                   and all remedies, benefits and contractual rights established
                   by said policy;

              J.   Debtor, through its Board of Directors, is authorized to take
                   all Debtor actions to effect the above as well as the actions
                   set forth in Article XIX;

                   agree to indemnify Debtor against any tax penalties resulting
                   from the amended and restated NEP Settlement, shall be deemed
                   to be ratified and in full force and effect; and

              L.   The Ownership Settlement Agreement, in which Messrs. Vogel
                   and Chamberlain give up all claims, if any, to any interest
                   in VivaTel shall be deemed to be ratified and in full force
                   and effect.

                   obligations.

              C.   Promptly after the Confirmation Date, the Debtor shall take
                   the following action;

                   1.   File a notice with the Secretary of State for the State
                        of Delaware to the effect that the amendment(s) to

                        1997, were filed without requisite shareholder approval
                        and are, therefore, invalid and void ab initio;

                   2.   Subsequent to its repurchase of the Series B Preferred,
                        file Amended and Restated Articles of Incorporation with

                        Amended Articles of Incorporation shall (among other
                        things): (i) extinguish the existing Series A, Series B

                        65.0% of the issued and outstanding Class A Common Stock
                        is required to amend the Articles of Incorporation , and
                        (iv) change the name of the Debtor to WorldCall, Inc.
                        Thereafter, new stock certificates will be issued; and

                   3.   Adopt amended and restated By-Laws.

              D.   Subsequent to the Declaration Date but at least 20 trading

                   reverse stock split such that the number of shares of Class A
                   Common Stock outstanding shall be no less than 500,000 shares
                   nor more than 20,000,000 shares, the exact ratio to be set by
                   the Debtor's Board of Directors.

              E.   The Debtor shall acquire 100% of the issued and outstanding
                   Common Stock of VivaTel in exchange for $500.00. Debtor will

                   Shares of Class A Common Stock is predicted to be equal to
                   35.0% of the issued and outstanding Class A Common Stock.

              F.   Debtor shall consent to the transfer of Class A Common Stock
                   in conjunction with the amended and restated NEP Settlement
                   Agreement such that sixteen (16) corporate entities shall
                   receive Class A Common Stock equal to 50.0% of the issued and
                   outstanding Class A Common Stock of Debtor computed ten (10)

              G.   All Class A Common Stock issued to a Creditor pursuant to
                   this Plan, shall be issued pursuant to section 1145 of the
                   Bankruptcy Code and shall be
<PAGE>   30
                   issued without a restrictive legend if the Creditor
                   establishes that the Creditor is not an "underwriter" as
                   defined in section 1145(b) of the Bankruptcy Code. The Class
                   A Common Stock to be issued to the exchanging shareholder of
                   Diego Tel shall be restricted and subject to significant
                   restraints on transfer as set forth in this Plan and in the
                   acquisition agreements.

         23.2 Amendment of Plan. The Plan may be amended by the Debtor before or
after the Effective Date as provided in section 1127 of the Bankruptcy Code.

ARTICLE XXIV.    PROVISIONS FOR MANAGEMENT

         24.1 Directors. Upon confirmation of the Plan, subject to the
Bankruptcy Court's approval under Bankruptcy Code section 1129(a)(5), the
reorganized Debtor shall have as directors of Debtor the directors for Debtor as
identified in the Disclosure Statement. These directors shall serve as directors
of Debtor after the Confirmation Date until removed or replaced by the
post-confirmation stockholders of Debtor. The tenure and manner of selection of
directors of Debtor shall be as
<PAGE>   35
provided in the Articles of Incorporation and By-Laws, as may be amended
pursuant to Article XXII hereof.

         24.2 Officers. Upon confirmation of the Plan, subject to the Bankruptcy
Court's approval under Bankruptcy Code section 1129(a)(5), the officers of
reorganized Debtor, as identified in the Disclosure Statement, shall serve as
officers of Debtor after the Effective Date. The Board of Directors shall elect
the officers of Debtor and shall specify the tenure of the individuals holding
those offices.

         24.3 Employment Contracts. Debtor may enter into employment contracts
with its respective officers, employees or others which shall only be operative
if the Plan is confirmed. Copies of any employment contracts that are to take
effect immediately after the Confirmation Date were filed with the bankruptcy
Court fifteen (15) days prior to the commencement of the hearing to consider the
Disclosure Statement. The employment contracts shall contain sufficient
information to comply with Bankruptcy Code section 1129(a)(5)(B) as to
disclosure of compensation to be paid to insiders who are the subject of
contracts and are subject to the approval of the Bankruptcy Court.

ARTICLE XXV.     EVENTS OF DEFAULT

         25.1 In the event that Debtor defaults under the provisions of the
Plan, any Creditor or party-in-interest desiring to assert such a default shall
provide Debtor with written notice of the alleged default. Debtor shall have 30
days from receipt of the written notice in which to cure the default. Such
notice shall be delivered by certified mail (return receipt requested) to the
attorneys for Debtor at the address stated on the final page hereof. If the
default is not cured within the 30-day cure period, any Creditor or
party-in-interest may thereafter file and serve upon counsel for Debtor a motion
to compel compliance with the applicable provision of the Plan. The Bankruptcy
Court,
<PAGE>   36
upon finding a material default, shall issue an order compelling compliance with
the applicable provisions of the Plan.

ARTICLE XXVI.    MISCELLANEOUS PROVISIONS

         26.1 Discharge of Debtors. The rights afforded in the Plan and the
treatment of all Creditors therein shall be in exchange for and in complete
satisfaction, discharge and release of all Claims or Equity Interests of any
nature whatsoever, including any interest accrued thereon from and after the
Petition Date against the Debtor or any of its assets or properties. Except as
otherwise provided herein, upon the Confirmation Date, in accordance with
section 1141 of the Bankruptcy Code, all such Claims or Equity Interests against
the Debtor shall be satisfied, discharged and released in full. All Creditors
and holders of Equity Interests shall be precluded from asserting against the
Debtor or its respective assets or properties any other or further Claims based
upon any acts or omission, transaction or other activity of any kind or nature
that occurred prior to the Confirmation Date.

         26.2 Title to Assets: Discharge of Liabilities. Except as otherwise
provided by the Plan, on the Confirmation Date, title to all assets and
properties dealt with by the Plan shall vest in Debtor in accordance with
section 1141 of the Bankruptcy Code, free and clear of all Claims and Equity
Interests; and the order confirming the Plan shall be a judicial determination
of discharge of the Debtor's liabilities except as provided in the Plan.

         26.3 Effect of Discharge on Rights Between Third Parties. If the Plan
is confirmed, the provisions of the Plan will bind the Debtor and all Creditors
and Equity Interest holders, whether or not they accept the Plan. Confirmation
will also discharge the Debtor from all debts that arose
<PAGE>   37
before confirmation as of the Confirmation Date, including intercompany
obligations (if any) owing by the Debtor to an affiliate, whether such affiliate
is itself a debtor.

         The classification and the manner of satisfying all Claims under the
Plan takes into consideration the existence of any guarantees by the Debtor of
any obligation of any person and the fact that the Debtor may be a joint obligor
with another person or persons, with respect to the same obligation. The Plan
also takes into account any contentions by Creditors or holders of Equity
Interests that the Claims of other Creditors or other holders of Equity Interest
may be subordinated by contract or pursuant to the Articles of Incorporation or
ByLaws of the Debtor. All Claims against the Debtor based upon any such
guarantees will be discharged in the manner provided in the Plan. Each Creditor
and stockholder will receive the distribution provided in the Plan, which will
not be subject to any Claim of another Creditor or stockholder by reason of any
claimed contractual right of subordination based upon any defaults occurring
prior to the Confirmation Date.

         The distributions of consideration provided for in the Plan will be in
exchange for and in complete satisfaction, discharge and release of all Claims
and Equity Interests, including any Claim for interest after the Petition Date.
On the Confirmation Date, all Creditors and existing Equity Interest holders
shall be precluded form asserting any Claim against the Debtor or its assets or
properties based upon any transaction or other activity of any kind that
occurred prior to the Confirmation Date; provided, however, that nothing
contained in the Plan will alter the legal, equitable and contractual right of
the holder of any Claim or Equity Interest specifically designated as being
unimpaired in the Plan, it being specifically intended that all such rights are
to remain unaltered by the Plan.
<PAGE>   38
         26.4 Filing of Additional Documents. On or before the Effective Date,
the Debtor shall file with the Bankruptcy Court such agreements, indentures,
supplemental indentures and other documents as may be necessary or appropriate
to effectuate and further evidence the terms and conditions of the Plan.

         26.5 Post Confirmation Acquisitions, Mergers and Stock Splits. In order
to fulfill its financial obligations to Creditors and to expand its operations,
it is anticipated that the Debtor will effect one or more acquisitions or
mergers subsequent to the Confirmation Date. For a two (2) year period
commencing with the Effective Date, Debtor will be permitted pursuant to this
Plan to effect acquisitions and mergers, additional stock splits and reverse
stock splits based solely upon the affirmative vote of its Board of Directors
and without the necessity of requesting and receiving the consent of the Debtor
shareholders.

         26.6 Class A Common Stock in Lieu of Cash. Any Creditor entitled to
receive Cash pursuant to this Plan may, by mutual agreement of the Creditor and
the Debtor, receive Class A Common Stock pursuant to terms and conditions to be
negotiated between the Creditor and the Debtor and agreed to by the Debtor and
the Creditor.

         26.7 Ratification of Settlements. Pursuant to Section 1123(b)(3)(A) of
the Bankruptcy Code, upon Confirmation of the Plan, the following settlements
are deemed to have been ratified by the Bankruptcy Court and are in full force
and effect: (1) the amended and restated NEP Settlement, (2) Ownership
Settlement Agreement, (3) the NEPC Indemnification, and (4) the settlements
entered into with respect to the claims set forth in Article III, Section G of
the Disclosure Statement.

         26.8 Ratification of Agreements. Upon Confirmation of the Plan, the
following contracts and agreements will be deemed to have been ratified by the
Bankruptcy Court: (1) the Agreement
<PAGE>   39
for the Exchange of Stock for the acquisition of Viva Telecommunications, Inc.
and (2) the amended and restated Agreement for the Exchange of Stock for the
Acquisition of Diego Tel, Inc. if and when amended and filed with the Bankruptcy
Court.

         26.9 Set Offs. Debtor may, but shall not be required, to set off
against any claim and the distribution to any holder under the Plan, claims of
any nature that Debtor may have against the holder of such claim. Allowance of a
claim or failure to exercise any right of set off with respect to a claim does
not constitute a waiver or release by Debtor of any rights or claims the Debtor
may have against the holder of such claim. Debtor's rights of set off may be
limited in the manner provided for in the Plan if such rights are not exercised
on or before the Effective Date. Debtor may exercise right of set off with
respect to claims for which it has payment responsibility.

         26.10 Fractional Shares. Debtor will not issue fractional shares of
Class A Common Stock. In the event that a Claimant is entitled to receive
fractional shares, the fractional share will be deemed to have been repurchased
from the Creditor by the Debtor based upon a per share purchase price of $.l0
per share.

         26.11. Section Headings. The section headings contained in the Plan are
for reference purposes only and shall not affect in any way the meaning or
interpretation of the Plan.

         Respectfully submitted this 24th day of July, 1998.
