5.      In consideration of the mutual releases as set forth herein and the
        consideration as set forth in the Recitals, the Parties to this Amended
        Agreement do hereby agree as follows:

   a.   The 1996 Agreement attached hereto as Exhibit 1 is hereby deemed to be 
        amended and restated in its entirety, except as set forth in this
        Amended Agreement and, therefore, remains legally binding upon all
        parties thereto. Notwithstanding the foregoing, NEPC and NEP shall
        reconvey to PowerTel (i) 100% of the issued and outstanding Common Stock
        of Combustion Energy Company, a Nevada corporation, and (ii) title to a
        parcel of real property situated at 403 Fourth Street, Reno, NV.

   b.   The Company and NEPC do hereby modify, amend and revise the Agreement of
        Limited Partnership of Nevada Energy Partners I, a Nevada limited
        partnership, retroactively to January 1, 1995 to provide that for the
        period January 1, 1995 through August 15, 1996 (i) 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, and (ii) the
        allocations of profits and loses to capital accounts shall be 99.0% of
        all profits and loses accredited and charged to the capital account of
        the limited partner and 1.0% of all profits and loses are charged and
        credited to the capital account of the general partner. The Parties
        stipulate that, commencing January 1, 1995 through August 15, 1996, NEPC
        is and shall be the sole general partner of NEP and the Company shall be
        the sole and exclusive limited partner of NEP. As of August 16, 1996,
        the Company specifically relinquishes, waives and forever abandons any
        claim or interest which it has or may have in or to any partnership
        interest of NEP. NEPC and the Company stipulate and acknowledge that,
        subsequent to January 1, 1995, cash distributions were made to NEPC and
        the Company pursuant to the 60/40 allocation set forth above. In
        addition, NEPC and the Company stipulate that on or about August 16,
        1996 (after withdrawal of NEC from NEP), NEP distributed to NEPC, as its
        general partner, Class B Common 
<PAGE>   5
        Stock of the Company totaling 4,437,473 shares which, thereafter NEPC
        sold to the corporations on a prorata basis. NEPC and the Company also
        stipulate that, as of August 16, 1996, NEP relinquished any and all
        rights which it had pursuant to the Plan of Reorganization involving
        Munson Geothermal, Inc. to receive additional Class A Common Stock and,
        thereby, waived and forever relinquished its right to receive additional
        Class B Common Stock in the amount of 8,808,485 shares.

   c.   The Company does specifically that on or about August 16, 1996 NEPC 
        converted the Class B Common to Class A Common and, further recognizes
        that NEPC sold to the Corporations the Class A Common Stock owned by
        NEPC as set forth above. The Company does hereby agree that NEPC shall
        retain any and all consideration paid or to be paid by the Corporations.
        In order to effect a permanent, common final and complete resolution of
        any and all disputes among the parties to this Agreement, the Company
        stipulates that the Class B Common Stock distributed to NEPC as of
        August 16, 1996 was convertible into Class A Common Stock at a ratio
        equal to 50.0% of the issued and outstanding Class A Common Stock as of
        August 16, 1996. Accordingly, the Company stipulates that the
        Corporations, by virtue of their purchase of the Class A Common Stock,
        are entitled to own Class A Common Stock. The Company further stipulates
        that, ten days after the Effective Date of the Plan of Reorganization,
        the Company shall adjust (i.e., increase or decrease) the number of
        shares of Class A Common Stock to be distributed to the Corporations
        such that the Corporations shall own 50.0% of the issued and outstanding
        Class A Common Stock as of the close of business ten days after the
        Effective Date of the Plan of Reorganization.

   d.   NEPC, as the General Partner of NEP shall wind up the affairs of the 
        partnership with all deliberate speed including but not limited to the
        preparation and filing of all requisite tax returns. The General Partner
        shall not charge the Limited Partner for the expenses of winding up the
        Partnership and the Limited Partner waives any right of reimbursement
        for any distribution to the General Partner prior to the date of this
        Agreement.

6.      In the event that the United States Bankruptcy Court fails to ratify
        this Agreement, this Agreement shall be voidable by any Party upon
        prompt notice to Company and NEPC. If the Agreement is voided, then any
        Property conveyed pursuant to this Agreement shall be returned to the
        grantor from whom or which it was received.

7.      Company shall have seventy-five (75) days from the Confirmation Date of
        the Plan of Reorganization to conduct any "due diligence,"
        investigation, inquiry and/or review ("Review") which it deems to be
        necessary of appropriate concerning any statement of fact, warranty,
        representation, consent and/or condition ("Represented Fact") made or
        given to Company by any other party to this Amended Agreement and upon
        which PowerTel has relied upon in the execution of this Amended
        Agreement. If on the basis of the Review, PowerTel
<PAGE>   6
        in its sole and absolute discretion concludes that any Represented Fact
        is inaccurate, false, misleading or deceptive, PowerTel has the right to
        revoke this Amended Agreement upon providing all other written notice of
        such termination and the basis therefor.

8.      The Parties to this Amended Agreement stipulate and acknowledge that a
        variety of supplemental documents may be necessary in order to
        effectuate the objectives anticipated by this Amended Agreement or to
        obtain ratification hereof by the United States Bankruptcy Court, and
        every party to this Amended Agreement does irrevocably commit to act in
        good faith to implement this Amended Agreement and to execute any
        additional documents necessary or appropriate to achieve the objective
        of this Amended Agreement and/or ratification hereof.

9.      This Amended Agreement shall be governed by the laws of the State of
        Nevada, without regard to its conflict of laws provision. Every party to
        this Amended Agreement consents to the exclusive jurisdiction of the
        United States Bankruptcy Court for the District of Nevada with regard to
        the enforcement, interpretation, or any other issue or claim arising as
        a result of this Amended Agreement.

10.     It is the intention to the Parties to this Amended Agreement that the
        1996 Agreement shall be amended and restated. Accordingly, to the extent
        that any party to this Amended Agreement has any contractual rights,
        causes of action, claims or other legal or equitable rights or remedies
        (collectively "Rights") which existed prior to the 1996 Agreement and
        were extinguished, waived, released or modified thereby, such Rights
        shall be deemed to be fully and completely restored and each party to
        this Amended Agreement does hereby agree that the Statute of
        Limitations, if any, which would otherwise operate as a bar to the
        prosecution of any cause of action or claim of any nature to enforce
        such Rights is hereby tolled and each party does irrevocably waive and
        agrees not to assert for a twelve (12) month term from the Settlement
        Date of this Amended Agreement the Statute of Limitations as a defense
        to the prosecution of any cause of action or claim of any nature to
        enforce such Rights which is restored by virtue of this Agreement.

                rata issuance of one share of Class B Common Stock for each
                share of Class A Common Stock issued and outstanding. The
                consideration for the issuance may be subject to a determination

<PAGE>   11
        b.      NEP has the right to an additional 8,808,485 shares of Class B

                Common Stock of NEC which shall be free trading without
                restrictions.

        d.      NEP herewith forbears forever from any and all claims for an
                additional 8,808,485 shares of Class B Common Stock of NEC.

4.      Withdrawal of NEC from NEP. NEC no longer desires to participate in the
partnership NEP and withdraws as follows:

        a.      NEC has participated in the Litigation since its inception. The
                counter-plaintiffs claim damages in excess of one million
                ($1,000,000.00) dollars and further damages to be proved against
                NEC.

        b.      NEC has contributed from time to time its pro rata share of
                attorney fees, legal costs and expenses.

        c.      There appears to be no possibility of settlement or resolution
                of the Litigation in the near future.

        d.      NEP was a partner with Hot Springs Power Company, a Nevada
                corporation in Nevada Geothermal Power Partners, a Nevada
                Limited Partnership. The Litigation arises out of the
                partnership relationship. The plaintiff and counter-defendant is
                NEP. The defendant and counter-plaintiff is Hot Springs Power
                Company.

        e.      Nevada Geothermal Power Partners has ceased doing business and
                has wound up its affairs. The only remaining relationship
                between the partners is the Litigation.

        f.      NEC hereby withdraws as a limited partner in NEP and waives
                further accounting except as necessary to prepare its federal
                tax returns. The effective date of the withdrawal shall be
                September 1, 1996.

5.      Release of NEC from the Litigation and further obligations of NEP. NEPC,
as general partner of NEP, hereby releases NEC from all further partnership
obligations and duties.

        a.      Pursuant to the partnership agreement, NEC was obligated to
                contribute to the attorneys' fees, legal costs and expenses of
                any litigation arising out of the partnership relationship.

        b.      Concurrent with the withdrawal of NEC as a limited partner, NEP
                releases NEC from any further contributions for attorneys' fees,
                legal costs or expenses with respect to the Litigation. NEP
                agrees to indemnify NEC for any damages arising out of the
                Litigation. NEC shall have the right to have its own co-counsel
                at its own expense.

        c.      NEPC, as general partner of NEP, will hereby guaranty the
                payment of attorneys' fees, legal costs and expenses by NEC for
                counsel under NEP's guidance and employ who will defend NEC's
                interests.

        d.      NEC agrees to cooperate in the prosecution and defense of the
                Litigation and to the extent possible, NEC waives its attorney
                client privilege in favor of NEP.
<PAGE>   12
6.      NEP releases all claims under the Order of the Bankruptcy Court. As the
sole recipient of Class B shares under order from the Bankruptcy Court, NEP 
waives any claims it may have for additional shares of Class B Stock without 
consideration as follows:

        a.      Rights and Restrictions. The rights and restrictions of the
                Class B Stock are as follows:

                i. Federal Bankruptcy Court's Plan of Reorganization. On
                November 20, 1990, the Bankruptcy Court of Nevada, by Order,
                required the amendment of the Certificate of Incorporation. The
                Order provided at page 25, "Class B Common Stock will have full
                voting rights but will have no participation in dividends. The
                terms of the Class B Common shares will also provide that, upon
                the issuance of any share, or fraction thereof, of Class A
                Common Stock, the owners of Class B Common Stock will
                contemporaneously have issued to them, on a pro rata basis, a
                number of shares of Class B Common Stock which is the same as
                the number of Class A Common shares then being issued.

                ii. Amendment of the Certificate of Incorporation. NEC (then
                Munson Geothermal, Inc.) amended its Certificate of
                Incorporation on November 20, 1990 (filed on December 3, 1990)
                and submitted a new paragraph defining NEC's capital, paragraph
                4-A. The new paragraph governed the description of all capital
                stock. The new paragraph authorized Class A Common Stock and
                Class B Common Stock. All Common Stock has a par value of $.001
                per share. All common stockholders (either Class A or Class B)
                received one vote for each whole share of stock. The Certificate
                authorized that Class A and Class B Common Stock would not
                participate in the earnings of the corporation through
                dividends. A Class B Common Stockholder would only receive funds
                from NEC by statute upon the sale, merger, or liquidation in the
                form of a liquidating distribution.

                iii. Voting Rights of the Class B Stock. Class B Stock shares do
                not receive dividends but would participate in distribution of
                proceeds if the NEC sells, merges or liquidates. Class B Stock
                shares are entitled to vote. Because the Class B Stock shares
                are entitled to fifty percent (50%) of the Common Stock, the
                Class B Stock shares are entitled to 50% of the votes.

                iv. Class B Stock and NEP. The Plan of Reorganization provided
                that immediately after the reorganization that NEP would own
                100% of the Class B Stock. According to the Plan of
                Reorganization, any holder of Class B Stock through NEP at the
                time of the reorganization was entitled to an additional share
                of Class B Stock for each share of Class A Stock issued.

                v. Conflict between the Plan of Reorganization and the
                Certificate regarding Issuance of Class B Stock. The Certificate
                provided that upon the issuance of any share of Class A Common
                Stock, NEC shall issue a pro rata amount of Class B Common Stock
                to Class B Stock holders. Only present shareholders of Class B
                Stock shares would be eligible to receive additional Class B
                Stock shares. Further, paragraph 4-D states, "such shares of
                Class B Common Stock shall be issued for such consideration as
                may be determined from time to time by the Board of Directors".
                (Emphasis added.) The Plan of Reorganization does not provide
                for payment of "consideration" in exchange for newly issued
                shares of Class B Stock.
<PAGE>   13
        b.      Concurrent with the exchange of shares, NEP forever waives and
                gives up any rights for additional Class B Stock without payment
                of consideration as provided in the Order of the Bankruptcy
                Court dated November 20, 1990.

7.      NEP transfers the shares of CEC. NEC herewith transfers to NEP all of 
NEC's six thousand (6,000) shares of CEC as follows:

        a.      NEC merged its wholly owned subsidiary, CEC, with a business
                known as Herth Printing and Business Supplies in 1994.

        b.      The business of CEC is not compatible with the general business
                plan of NEC.

        c.      The shares of CEC are not registered as described in section
                8.d.

        d.      In consideration of the obligations assumed by NEP under this
                agreement, NEC herewith transfers and assigns all rights, title
                and interest to the shares and assets of CEC to NEP. The
                effective date of the transfer shall be September 1, 1996.

                hypothecation, or other transfer thereof.

                Securities Act, set forth in the Nevada Revised Statutes, as
                amended (the "Nevada Act"), and were acquired by NEC pursuant to
                a exemption.

                vi. NEC reasonably believes that NEP is obtaining the shares for
                investment and has no information to the contrary.

        e.      Disclosure. The representations and warranties contained in this
                Section 9.e do not contain any untrue statements of a material
                fact or omit to state any material fact necessary in order to
                make the statements and information contained in this Section 9
                not misleading.

        c.      Costs and Expenses. Each party hereto agrees to pay its own
                costs and expenses, including legal, accounting, consultant, and
                advisor fees, incurred in negotiation this Agreement and
                consummating the transactions described herein.

        d.      Time. Time is of the essence.

        e.      Entire Agreement. This Agreement constitutes the entire
                agreement between the parties hereto with respect to the subject
                matter hereof.

        f.      Amendment. This Agreement may not be amended, supplemented or
                modified in whole or in part except by an instrument in writing
                signed by the party against whom enforcement of any such
                amendment, supplement or modification is sought.

        g.      Assignment. NEC may not assign this Agreement to any affiliated
                entity or nominee or to any party hereto without the prior
                written consent of the NEP
<PAGE>   18
        h.      Choice of Law. This Agreement will be interpreted, construed and
                enforced in accordance with the laws of the State of Nevada,
                without regard to conflicts of law.

        i.      Dispute Arbitration. NEC and NEP intend to provide a speedy and
                informal method for resolving all disputes and other matters in
                question arising out of, or relating to, this Agreement, which
                involves interstate commerce and is subject to the Federal
                Arbitration Code. All disputes and other matters in question, of
                any kind, between NEC and NEP arising out of, or relating to
                this Agreement, shall be decided by binding arbitration in
                accordance with the Commercial Arbitration Rules of the American
                Arbitration Association then in effect. The decision of the
                arbitrator shall be binding. The arbitrator is specifically
                granted authority and directed to award reasonable attorneys'
                fees, expenses and costs to the successful party. A court of
                competent jurisdiction may be used to enforce, but not to appeal
                or challenge, the arbitrators' decision including the award of
                attorneys' fees, expenses and costs. If it becomes necessary to
                enforce the arbitrators' decision at either the trial or
                appellate level, a reasonable attorney fee for the enforcement
                of the arbitrators' decision shall become an additional item of
                damages. Any suit between NEC and NEP must be brought in Washoe
                County, Nevada. NEC consents to personal jurisdiction in Nevada.

        j.      Construction. NEC and NEP and their respective legal counsel
                participated in the preparation of this Agreement, therefore,
                this Agreement shall be construed neither against nor in favor
                of any of the parties hereto, but rather in accordance with the
                fair meaning thereof.

        k.      Effect of Waiver. The failure of any party at any time or times
                to require performance of any provision of this Agreement will
                in no manner affect the right to enforce the same. The waiver by
                any party or any breach of any provision of this Agreement will
                not be construed to be a waiver, by any such party of any
                succeeding breach of that provision or a waiver by such party or
                any breach of any other provision.

        l.      Severability. The invalidity, illegality or unenforceability of
                any provision of this Agreement, which will remain in full force
                and effect, nor will the invalidity, illegality or
                unenforceability of a portion of any provision of this Agreement
                affect the balance of such provision. In the event that any one
                or more of the provisions contained in this Agreement or any
                portion thereof shall for any reasons be held to be invalid,
                illegal or unenforceable in any respect, this Agreement shall be
                reformed, construed and enforced as if such invalid, illegal or
                unenforceable provision had never been contained herein.

        m.      Binding Nature. This Agreement, including the requirement to
                arbitrate, will be binding upon and will enure to the benefit of
                any successors of the parties hereto.

        n.      Counterparts. This Agreement is intended to be executed in more
                than one counterpart, including facsimile counterparts. Each
                counterpart shall be 
<PAGE>   19
                deemed an original on all of which shall constitute one and the
                same instrument.


        IN WITNESS WHEREOF, NEP and NEC have executed this Agreement.

TO:     PowerTel USA, Inc., A Delaware, USA, corporation (Referred to as
        "PowerTel")

FROM:   XXXXXXXXX, XXX., a Company Limited by Shares under the International
        Business Companies Act of 1989, Commonwealth of the Bahamas (Referred to
        as "XXXXXXX"), with mailing address at XXXXXXXXXXXXX.

RE:     Receipt of Class A Common Stock Pursuant to the Plan of Reorganization
        of PowerTel

        PowerTel USA, Inc. ("PowerTel") and XXXXXXX have entered into a First
Amended and Restated Settlement and Release Agreement effective as of December
1, 1997 (the "Agreement"), which Agreement was subsequently incorporated into
and made a part of a Plan of Reorganization (the "Plan") filed by PowerTel with
the United States Bankruptcy Court for the District of Nevada in a Chapter 11
proceeding identified as Case No 97-30265-BMG.

        Pursuant to the Plan, XXXXXXX is to receive Class A Common Shares (the
"Shares") to be issued by PowerTel pursuant to Section 1145 of the United States
Bankruptcy Code. In consideration of the issuance of the Shares, XXXXXXX
represents and warrants to PowerTel and to the Court that XXXXXXX is not an
"underwriter" as that term is defined in Section 1145(b) of the Bankruptcy Code.
XXXXXXX also acknowledges that the Shares which it will receive have not been
registered with the United States Securities and Exchange Commission pursuant to
Section 5 of the Securities Act of 1933 in reliance upon the exemption from
registration provided in Section 1145(a) of the Bankruptcy Code. XXXXXXX also
confirms that it has been advised that PowerTel has consented to the issuance of
the Shares based upon PowerTel's understanding that XXXXXXX is experienced in
financial matters, has access to advisors who are experienced in evaluating
investments and is ready, willing and able to assume the risk of acquiring a
speculative, high risk investment, such as the Shares.

        XXXXXXX also confirms that it has received and reviewed the FIRST
AMENDED DISCLOSURE STATEMENT PURSUANT TO 11 U.S.C. Section 1125 filed by
PowerTel and has been afforded an opportunity to make inquiry into the affairs
of PowerTel, including an opportunity to confer with the Directors and Officers
of PowerTel. XXXXXXX has been advised that, for the preceding three calendar
years, PowerTel has made various filings with the Securities and Exchange 
Commission (including but not limited to annual reports on Form 10-KSB,
quarterly reports on Form 10-QSB and at least one registration statement on 
Form S-8). XXXXXXX acknowledges that a copy of these filings is available upon
request or may be procured from the United States Securities and Exchange 
Commission, Washington, D.C.

        XXXXXXX acknowledges that PowerTel has not made any representation or
warranty that (i) its Plan will be implemented successfully, (ii) there will be
a market for the Shares or (if there is a market) that the per Share price will
be maintained within any specific bid/ask range, or (iii) PowerTel will be
financially solvent or that its pro forma financial projections will materialize
as anticipated.

        XXXXXXX is aware that there are various Federal and State statutes,
rules and regulations in the United States governing the offer and sale of
securities. XXXXXXX is also aware that the Securities Exchange Act of 1934
imposes duties and responsibilities upon certain shareholders, officers and
directors. XXXXXXX represents that it shall comply with all applicable statutes,
rules and regulations.

        Except as set forth in the Agreement and the Plan, XXXXXXX acknowledges
that there is no agreement, contract or understanding (either oral or written)
by and between XXXXXXX and PowerTel. XXXXXXXXX further acknowledges the
authority and ratifies the signature of Jeffrey Antisdel on the First Amended
and Restated Settlement and Release Agreement on behalf of XXXXXXXXXXXXXXX.

        XXXXXXX acknowledges that both PowerTel and the United States Bankruptcy
Court will rely upon this Memorandum in issuing the Shares.


        In Witness Whereof, XXXXXXXXX, XXX., has given its Common Seal this
date.

Settlement and Release Agreement dated as of December 1, 1997 (the "Agreement"),
which Agreement was subsequently incorporated into and made a part of a Plan of
Reorganization (the "Plan") filed by PowerTel with the United States Bankruptcy
Court for the District of Nevada in a Chapter 11 proceeding identified as Case

"Shares") to be issued by PowerTel pursuant to Section 1145 of the United States

PowerTel and to the Court that Maitland is not an "underwriter" as that term is

States Securities and Exchange Commission pursuant to Section 5 of the
