                      AGREEMENT AND PLAN OF REORGANIZATION

         Agreement and Plan of Reorganization ("Agreement") dated as of August
21, 2000 (the "Signing Date") by and among NEXTEL COMMUNICATIONS, INC., a
Delaware corporation ("Nextel"), NEXTEL FINANCE COMPANY, a Delaware corporation
and a direct, wholly-owned subsidiary of Nextel ("Acquisition Sub") and
CHADMOORE WIRELESS GROUP, INC., a Colorado corporation ("Chadmoore").

                             PLAN OF REORGANIZATION

         A        Nextel and Chadmoore intend to enter into a transaction that
will be recognized as a plan of reorganization under the provisions of Section
368(a)(1)(C) of the Internal Revenue Code of 1986, as amended (the "Code").

         B        The plan of reorganization will comprise the acquisition by
Acquisition Sub of substantially all of the SMR wireless business of Chadmoore
(the "Business"), and substantially all of the assets employed in the Business,
together with certain liabilities, of Chadmoore.

         C        The acquisition of the Business by Acquisition Sub will be
effected by a transaction (the "Reorganization") wherein Chadmoore will exchange
the Assets for that number of shares of Nextel Class A Common Stock, par value
$.001 per share ("Nextel Shares"), equal to an aggregate of $160,000,000, as
determined in accordance with Article 2 of this Agreement.

         E        The Assets owned by Chadmoore and to be acquired by
Acquisition Sub by virtue of the Reorganization will include, without
limitation, all of Chadmoore's rights and interests in and to the Federal
Communications Commission ("FCC") licenses (the "Licenses") listed in Sections
1.01(a)(1),(2) and (3) of the Disclosure Schedule to this Agreement (the
"Disclosure Schedule") for the 800 MHz and 900 MHz frequencies listed in Section
1.01(a) of the Disclosure Schedule (the "Channels") (except for any Channels or
Licenses not Delivered as described in Section 1.05), as well as the related
physical assets of the relevant systems operated in accordance with the Channels
(the "Systems") (including all repeater and ancillary equipment and leased real
property) and the related intangible assets of the Systems.

         F        On or about the date of the execution and delivery of this
Agreement, Nextel is arranging or providing funding for Chadmoore (as set forth
in Section 5.04) which present and future advances will be secured by a lien on
the assets of Chadmoore.

         G        Each of the directors, officers of Chadmoore and Recovery
Equity Investors II, L.P., each of which is a holder of Chadmoore's Common
Stock, $.001 per share, has committed in writing that he or it will vote in
favor of the Reorganization and the transactions contemplated by this Agreement.

<PAGE>

                                    AGREEMENT

         In order to consummate the Reorganization, and in consideration of the
mutual agreements hereinafter contained, Nextel, Acquisition Sub and Chadmoore
agree as follows:

ARTICLE 1      PURCHASE AND SALE OF THE ASSETS AND LIABILITIES;
               PURCHASE PRICE

    Section 1.01   Purchase and Sale of Assets. Except as to the Excluded Assets
described in Section 1.02, and as otherwise provided in Section 1.03, Chadmoore
will sell, transfer and assign to Acquisition Sub or its designee, as the case
may be, and Acquisition Sub, or its designee, as the case may be, will acquire
from Chadmoore, on the terms and conditions in this Agreement, substantially all
of the assets, properties and business of Chadmoore relating to the Business as
a going concern (all of which are collectively referred to herein as the
"Assets") including, without limitation, the following:

            (a) All of Chadmoore's rights and interests in the Licenses and
Channels, including, without limitation, those described in Sections 1.01(a)(1),
1.01(a)(2) and 1.01(a)(3) of the Disclosure Schedule;

            (b) The leasehold interest of Chadmoore in each of the site leases
for real property described in Section 1.01(b) of the Disclosure Schedule (the
"Site Leases") (except for any Site Leases that are not assignable as described
in 1.08(b));

            (c) All of Chadmoore's rights and interests in the Contracts
described in Section 1.03(a)(ii) of the Disclosure Schedule;

            (d) All of Chadmoore's equipment and other tangible personal
property related to or used in the Business, including, without limitation,
those described in Section 1.01(d) of the Disclosure Schedule; and

            (e) All records (copies and/or originals where necessary) of
Chadmoore (other than Chadmoore's corporate records) relating to the Business,
including customer lists, property records, service records, contract records
and accounting records.

    Section 1.02   Excluded Assets. Notwithstanding anything in Section 1.01 to
the contrary, there shall be excluded from the Assets to be transferred to
Acquisition Sub all of the assets of Chadmoore relating to the Business listed
or described in Section 1.02 of the Disclosure Schedule (collectively, the
"Excluded Assets").

                                      -2-
<PAGE>

    Section 1.03   No Liens; Assumption of Liabilities.

            (a) The Systems and Assets shall be sold free and clear of all
liens, encumbrances and security interests of any kind or nature, and
Acquisition Sub shall assume the following (the "Assumed Liabilities"), but no
other, obligations of Chadmoore:

                (i) Executory obligations under the Site Leases disclosed in
Section 1.01(b) of the Disclosure Schedule relating to periods of operation
after the Closing Date; and

                (ii) Executory obligations under all contracts of Chadmoore, as
disclosed in Section 1.03(a) of the Disclosure Schedule, in effect as of this
date, and relating to periods of operation after the Closing Date
(collectively with the Site Leases, the "System Contracts").

            (b) Except for the Assumed Liabilities, Acquisition Sub shall not,
by execution and delivery of this Agreement or otherwise, assume or otherwise be
responsible for any liability or obligation of any nature of Chadmoore, whether
related to the Business, the Assets or any of Chadmoore's other assets,
operations, businesses or activities, if any, or claims for any liability or
obligation, whether matured or unmatured, liquidated or unliquidated, fixed or
contingent, known or unknown, arising from occurrences prior to, at or after the
Closing Date (collectively, the "Excluded Liabilities"). Without limiting the
generality of the foregoing, neither Acquisition Sub nor Nextel shall assume,
and Chadmoore shall be responsible for, any obligation or liability of Chadmoore
to distribute to the shareholders of Chadmoore, the option holders of Chadmoore
or the holders of any other derivative securities of Chadmoore the Nextel Shares
received by Chadmoore in accordance with this Agreement.

Section 1.04      Purchase Price; Adjustments.

            (a) As the purchase price for the Assets, Acquisition Sub will,
concurrent with the Closing, assume the Assumed Liabilities and cause to be
issued to Chadmoore that number of Nextel Shares equal to an aggregate of
$160,000,000 (subject to adjustment in accordance with Sections 1.05 and 1.06)
(as so adjusted, the "Adjusted Enterprise Value") divided by $57.1656, subject
to adjustment in accordance with Sections 1.04(b) through (f) (the "Purchase
Price").

            (b) If the Nextel Closing Price is greater than $57.1656 but less
than or equal to $68.5988, then no adjustment to the Nextel Shares or the
Adjusted Enterprise Value shall be made.

            (c) If the Nextel Closing Price is greater than $68.5988 then the
number of Nextel Shares shall equal 120% of the Adjusted Enterprise Value
divided by the Nextel Closing Price.

            (d) If the Nextel Closing Price is less than $57.1656 but greater
than $45.7325, then no adjustment to the number of Nextel Shares or the Adjusted
Enterprise Value shall be made.

                                      -3-
<PAGE>

            (e) If the Nextel Closing Price is less than or equal to $45.7325
but greater than $37.1577, then the number of Nextel Shares shall equal the 80%
Adjusted Enterprise Value divided by the Nextel Closing Price.

            (f) If the Nextel Closing Price is less than or equal to $37.1577,
then the number of Nextel Shares shall equal 80% of the Adjusted Enterprise
Value divided by $35.1577.

            (g) If Chadmoore has elected (as permitted by Section 9.01(c)(iv))
to terminate this Agreement because the Nextel Closing Price is less than
$37.1577, Nextel may elect, within ten (10) business days, to exceed the number
of shares deliverable under Section 1.04(f) and to deliver the number of Nextel
Shares that equals 80% of the Adjusted Enterprise Value divided by the Nextel
Closing Price.

            (h) If Nextel makes the election contemplated by Section 1.04(g),
then: (i) the termination election made by Chadmoore under Section 9.01(c)(iv)
shall be automatically rescinded and cancelled; and (ii) the Reorganization
shall proceed in accordance with this Agreement.

            (i) For purposes of this Agreement, the "Nextel Closing Price" per
share of Nextel common stock shall be the daily closing price per share for the
twenty (20) consecutive Trading Days immediately prior to the Closing Date. If
the Nextel Closing Price or the Nextel Signing Price per share is determined
during a period following the announcement by Nextel of (i) a dividend or
distribution on Nextel Shares payable in Nextel Shares or securities convertible
into Nextel Shares or (ii) any subdivision, reverse stock split or comparable
reclassification of Nextel Shares, and prior to the expiration of the requisite
twenty (20) Trading Day period after the dividend date for the ex-dividend or
distribution, or the record date for the subdivision, reverse stock split or
comparable reclassification, then, in each such case, the Nextel Closing Price
or the Nextel Signing Price shall be properly adjusted to take into account
ex-dividend trading. The closing price for each Trading Day shall be the last
sale price, or, in case no sale takes place on such day, the average of the
closing bid and ask prices, in either case, as reported by the NASDAQ National
Market. For purposes of this Agreement, the term "Trading Day" shall mean a day
on which the NASDAQ National Market is open for business.

    Section 1.05   Purchase Price Adjusted for Channels Not Delivered.

            (a) If at the time of the Closing the aggregate value of Channels
not Delivered by Chadmoore exceeds $3,200,000, then the value of each Channel
that is not Delivered will reduce the Adjusted Enterprise Value by the value of
such Channel. Channels shall be valued as set forth on Schedule 1.05. If at the
time of the Closing any Channel set forth on Schedule 1.01(a)(2) is not
delivered by Chadmoore, there shall be no adjustment to the Adjusted Enterprise
Value; provided, however, that the value of any such Channel that is Delivered
at the Closing shall be offset against any reduction to the Adjusted Enterprise
Value pursuant to the first sentence of this Section 1.05(a).

            (b) A Channel shall be "Delivered" by Chadmoore if at the Closing
Date: (i) the FCC license for such channel has been granted to Chadmoore or a
Chadmoore Subsidiary

                                      -4-
<PAGE>

by a Final Order; (ii) there is a Final Order approving a transfer of control of
that license to Nextel; (iii) if unconstructed or deconstructed, there are at
least one hundred eighty (180) days remaining before the construction or
reconstruction deadline applicable to that channel; (iv) there is no co-channel
license located within 54.7 miles of the channel, except for co-channel licenses
that are Chadmoore, Chadmoore Subsidiaries, or licenses controlled by Nextel or
which was incompliance with the FCC's short-spacing table on the date the
license was initially granted; (v) the channel is set forth on Schedule
1.02(a)(1) and is either a land mobile 800 MHz, 900 MHz or 450 MHz frequency,
for specialized mobile radio ("SMR") use, or a frequency allocated for public
safety, industrial land transportation or business where the radio service
classification has been converted to commercial service classification (i.e., YX
or GX radio service type); (vi) the channel is granted pursuant to a primary
license; (vii) such channel is a discrete frequency within the applicable market
and not subject to any cross border frequency sharing or channel coordination or
similar arrangement, taking into account all frequencies deemed Delivered
pursuant to this Agreement in that market; (viii) the license for or including
the channel is not subject to (A) any agreement to be sold to a third party, or
(B) any option or right of first refusal in favor of any third party; (ix)
except as approved by Nextel and set forth on Schedule 2.24, there is no
contract right of any third party or FCC order otherwise encumbering or limiting
the use of the license; (x) except as set forth in any Schedule referencing this
Section, which amounts shall be paid in full by Chadmoore within ten (10) day of
the Closing, no consideration is due to any person in connection with the
channel; and (xi) the channel is not subject to any finders' preference action
or otherwise included within any proceeding commenced or asserted by a third
party (other than Nextel) or any regulatory agency, including, without
limitation, the FCC, that could result in a take-back, termination, cancellation
or nonrenewal of the relevant licenses.

    Section 1.06   Adjustment for Nextel Funding. Not less than three (3) days
prior to the Closing, Chadmoore shall provide Nextel with written notice as to
the aggregate amount of cash it will deliver to Nextel at the Closing to repay
some or all of the Advances (as defined in Section 5.04) (the "Repayment
Amount"). The Advances, as reduced by the Repayment Amount, shall be subtracted
from $160,000,000 (as adjusted pursuant to Section 1.05) to determine the
Adjusted Enterprise Value.

    Section 1.07   Other Adjustments; No Fractional Shares.

            (a) If any of the following transactions (each a "Special
Transaction") becomes effective: (i) a capital reorganization, combination or
reclassification of the capital stock of Nextel; (ii) a consolidation or merger
of Nextel with another entity; or (iii) a sale or conveyance of all or
substantially all of Nextel's assets, then provision shall be made whereby
Chadmoore shall thereafter have the right to receive, upon the basis and upon
the terms and conditions specified herein, and in lieu of the Nextel Shares
otherwise deliverable hereunder, such shares of stock, other voting securities,
cash or other assets as may be issued or payable in and pursuant to the terms of
such Special Transaction with respect to or in exchange for the number of shares
of Common Stock equal to the number of Nextel Shares issuable hereunder had such
Special Transaction not taken place. In connection with any Special Transaction,
appropriate provision will be made with respect to the provisions of this
Agreement (including, without limitation, provisions for any adjustment of
Section 1.04) to the end that this Agreement

                                       5
<PAGE>

shall thereafter provide for delivery of shares of stock, other voting
securities, cash or other assets as were delivered for Nextel Shares in
connection with the Special Transaction.

            (b) Notwithstanding any other provision of this Agreement, no
fractional Nextel Shares shall be issued in accordance with the transactions
contemplated herein. In lieu of issuance of any fractional Nextel Shares, cash
adjustments will be paid to Chadmoore in respect of any fractional Nextel Shares
that would otherwise be issuable. Wherever in this Agreement it is contemplated
that, in connection with the Reorganization, cash payment shall be made in lieu
of a fractional share, Nextel may deliver to Chadmoore a number of whole shares,
determined by rounding up to the nearest whole share, and thereupon shall be
relieved of any obligation hereunder to make cash payments to Chadmoore in lieu
of any fractional share interest.

    Section 1.08   Assignability and Consents.

            (a) Required Consents. Schedule 2.25 sets forth a list of all
Assets, including, without limitation, permits, System Contracts, Channels and
Licenses, that are non-assignable or non-transferable or cannot be subleased to
Nextel or Acquisition Sub without the consent of some other individual,
partnership, corporation, association, joint stock company, trust, joint
venture, limited liability company or similar entity or any governmental entity
(collectively, "Person"). Promptly after the public announcement by Chadmoore of
this Agreement and the transactions contemplated herein, Chadmoore shall use all
commercially reasonable efforts to obtain all consents, novations, approvals,
authorizations, requirements (including filing and registration requirements),
waivers and agreements ("Consents") from any Persons necessary to authorize,
approve or permit the full and complete sale, conveyance, assignment, sublease
or transfer of the Assets, and to consummate and make effective the transactions
contemplated by this Agreement and to continue such efforts as may be required
after the Closing Date to facilitate the full and expeditious transfer of legal
title, or the sublease, as the case may be, of the Assets.

            (b) Nonassignable Items. Anything in this Agreement to the contrary
notwithstanding, this Agreement shall not constitute an Agreement to sell,
convey, assign, sublease or transfer any Assets, including permits, System
Contracts, Channels and Licenses, if an attempted sale, conveyance, assignment,
sublease or transfer thereof, without the Consent of any Person would constitute
a breach of, or in any way affect the rights of Chadmoore or Nextel or
Acquisition Sub with respect to such Asset ("Nonassignable Items"). Chadmoore
shall use its commercially reasonable efforts and Nextel and Acquisition Sub
shall cooperate in seeking to obtain all Consents and to resolve all
impracticalities of sale, conveyance, assignment, sublease or transfer necessary
to convey to Nextel or Acquisition Sub all Nonassignable Items without any
change to the terms of such items. If any such Consents are not obtained and
satisfied or if an attempted sale, conveyance, assignment, sublease or transfer
would be ineffective, Chadmoore and its appropriate affiliates shall at the
Closing enter into such arrangements (including related written agreements) as
Nextel may reasonably request in order to fairly compensate Nextel for the net
loss of, or to provide to Nextel the benefit of, any such Nonassignable Items
(it being acknowledged that such arrangement may include obligations imposed on
Chadmoore and such affiliates promptly to pay to Nextel when received all monies
and other items of value received by Chadmoore and such affiliates under such
Nonassignable Item; provided, however, that Chadmoore shall have no obligation
to provide Nextel the benefit

                                      -6-
<PAGE>

of any Nonassignable Item until Nextel has used its commercially reasonable
efforts to resolve such impracticality).

            Section 1.09 Tax Consequences. The parties intend that for United
States Federal income tax purposes, (a) the sale of Assets shall constitute a
tax-free reorganization within the meaning of Section 368(a)(1)(C) of the Code,
and (b) this Agreement shall constitute a "plan of reorganization" for purposes
of Section 354 and Section 361 of the Code.

enforceable against Chadmoore in accordance with its terms, except as

            (c) All Employee Plans are being, and have been, maintained,
operated and administered in all material respects in accordance with their
respective terms and in compliance with all applicable laws.

            (d) The execution, delivery and performance of this Agreement will
not, either alone or in conjunction with any other event or events, (i)
constitute a stated triggering event under any Employee Plan that will result in
any payment (whether of severance pay or otherwise) becoming due from Chadmoore
or any Subsidiary to any present or former officer, employee, director,
shareholder or consultant, or former employee (or dependents of any thereof), or
(ii) accelerate the time of payment or vesting, or increase the amount, of
compensation due to any employee, officer, director, shareholder or consultant

their respective dates (as amended through the Signing Date), contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances in which they were made, not misleading. The representations
made in this Section shall also be deemed to be made by Chadmoore to Nextel

            (c) Condition of Systems. All of the properties, equipment and
systems owned and/or operated by Chadmoore and related to the FCC licenses set
forth on a Schedule with reference to this Section are, and any such properties,
equipment and systems added in connection with any contemplated system expansion
or construction prior to the Closing will be, in compliance with all standards
or rules imposed by any governmental agency or authority (including, without
limitation, the FCC, the Federal Aviation Administration and (if applicable),
any public utilities commission or other state or local governments or
instrumentalities) applicable to Chadmoore or its operation of the properties,
equipment and systems or as imposed under any agreements with customers. All of
the equipment and systems owned and/or operated by Chadmoore are in good repair
and working order, ordinary wear and tear excepted.

            (d) Fees; License Compliance. Chadmoore has paid or will pay at
Closing all franchise, license or other fees and charges which have become due
in respect of the Business and has made appropriate provision as is required by
GAAP, consistently applied, for any such fees and charges which have accrued.
Except as set forth in a Schedule with reference to this Section, Chadmoore has
duly secured all necessary permits, licenses, consents and authorizations from,
and has filed all required registrations, applications, reports and other
documents with, the FCC and, if applicable, any public utilities commission and
other entity exercising jurisdiction over the SMR businesses, radio paging
businesses and other radio communications businesses of Chadmoore or the
construction of delivery systems therefor, as such businesses are currently
conducted. Chadmoore or a Subsidiary holds or has the contractual right to
obtain the FCC Licenses specified on a Schedule with reference to this Section
and, except as indicated in such Schedule, all such FCC Licenses are valid and
in full force and effect without conditions except for such conditions as are
stated on the FCC License or as are generally applicable to holders of similarly
situated FCC Licenses. Chadmoore has filed with the FCC prior to any applicable
deadline a complete and accurate application for rejustification of any
unconstructed or deconstructed FCC License related to previously granted or
requested wide area Enhanced Specialized Mobile Radio ("ESMR") licenses. Except
as set forth on a Schedule with reference to this Section, with regard to FCC
Licenses related to wide area ESMR frequencies, neither Chadmoore nor any of its
Subsidiaries is subject to a short space agreement or any other agreement, FCC
waiver or otherwise applicable regulations encumbering or limiting the use of
such FCC License. Except as set forth on a Schedule with reference to this
Section, to the knowledge of Chadmoore all applicable loading requirements with
respect to any SMR Licenses listed on such Schedule have been met and Chadmoore
has taken every reasonable action to cause the same to be loaded in compliance
with FCC regulations. Except as set forth on a Schedule with reference to this
Section, no event has occurred and is continuing which could (i) result in the
revocation, termination or adverse modification of any FCC License listed on
such Schedule, or (ii) adversely affect any rights of Chadmoore thereunder.
Except as indicated on a Schedule with reference to this Section, Chadmoore has
no reason to believe and no knowledge that all of the FCC Licenses specified on
a Schedule with reference to this Section will not be renewed in the ordinary
course. Except with regard to any planned enhanced SMR Systems of Chadmoore and
except as shown on a Schedule with reference to this Section, Chadmoore has

                                      -18-
<PAGE>

sufficient time, materials, equipment, contract rights and other required
resources to complete, in a timely fashion and in full, construction of all the
SMR Systems, radio paging and other radio communications systems associated with
the FCC Licenses listed on a Schedule with reference to this Section in
compliance with all applicable technical standards and construction requirements
and deadlines. Except as set forth on a Schedule with reference to this Section,
the current ownership and operation by Chadmoore of such SMR Systems, radio
paging and other radio communications systems comply with the Communications Act
of 1934, as amended (the "Communications Act"), and all applicable rules,
regulations and policies of the FCC.

            (e) Management Agreements. Set forth on a Schedule with reference to
this Section is a complete and correct list of all Chadmoore Management
Agreements (and associated option agreements, if any) and Third-Party Management
Agreements to which Chadmoore or any Subsidiary is a party that correctly
identifies the manager under each such agreement and the holder of the SMR
Licenses which are the subject of such agreements, the transmitter locations (by
address), and number of channels covered by such SMR Licenses, the term of such
agreements, any options or calls (and the respective option or call prices as
well as the time period in which any option or call must be exercised or made)
in favor of any party to such agreements to purchase or sell any interest in
such SMR Licenses and the respective fees or revenues payable or receivable
under any such agreements. All Management Agreements are on one of three forms
of management agreement that Chadmoore has previously provided to Nextel. Except
as set forth on a Schedule with reference to this Section, to the knowledge of
Chadmoore the terms of all such Chadmoore Management Agreements and Third-Party
Management Agreements and the operation of each SMR System pursuant thereto
comply with the Communications Act and all applicable rules, regulations and
policies of the FCC. Except as set forth on a Schedule with reference to this
Section, none of the channels licensed to Chadmoore or its Subsidiaries are
subject to a Third-Party Management Agreement. Each Chadmoore Management
Agreement includes an option allowing Chadmoore or a Subsidiary to purchase the
channels that are subject to that agreement and no such option will be adversely
affected by this Agreement.

    Section 2.25 Approvals. Set forth on a Schedule with reference to this
Section are all of the Consents that must be obtained or satisfied by Chadmoore
to transfer the Assets, including, without limitation, all Consents that must be
obtained pursuant to Section 1.10(a). All Consents prescribed by any law or
regulation, or any contract, agreement, commitment or undertaking, and which
must be obtained or satisfied by Chadmoore for the consummation of the
transactions contemplated by this Agreement, or for the continued performance by
them of their rights and obligations thereunder, have been, or shall by the
Closing have been, made, obtained and satisfied.

    Section 2.26    Information in Registration Statement. The information,
regarding Chadmoore, its subsidiaries and affiliates, included in the
Registration Statement referred to in Sections 4.4 and 5.2 of this Agreement
will not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the

    Section 2.27 Current Funding Requirements. The $5,200,000 being advanced on
or as soon as reasonably practicable after the Signing Date will cause
Chadmoore's obligations to be current as of such date (including any deferred
obligations). The cash flow statement prepared by Chadmoore and attached hereto
as Annex A accurately reflects in all material respects the cash flow of
Chadmoore and its Subsidiaries on a consolidated basis for each month of January
through June, 2000 and the forecast for each month from August 2000 through
March 2001 is based on Chadmoore's historical operations and is the best
estimate of the executive officers of Chadmoore of the anticipated cash
requirements of Chadmoore and its subsidiaries on a consolidated basis for each
month in the period.

thereunder; except that Chadmoore shall have no liability or obligation for any
information other than the Chadmoore Information.

            (b) Chadmoore shall instruct its accountants to deliver and shall
use its commercially reasonable efforts to cause its accountants, Arthur
Andersen LLP, to deliver to Nextel letters dated at the time the Registration
Statement becomes effective and as of the Closing, addressed to Nextel, each
containing such matters as are customarily contained in auditors' letters
regarding information about Chadmoore and its Subsidiaries expressly for
inclusion in the Registration Statement, and in a form and substance reasonably
satisfactory to Nextel.

    Section 4.05  Antitrust Filing. In connection with the transactions
contemplated by this Agreement, Chadmoore (and, to the extent required, its
affiliates) shall promptly file or cause to be filed any reports, documents,
filings or other data required to be filed by Chadmoore pursuant to the
Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act") and the
rules and regulations promulgated thereunder, and shall use its commercially
reasonable efforts to respond as promptly as practicable to all inquiries
received for additional information or documentation.

    Section 4.06   Restraint on Solicitations. From the date of this Agreement
until the Closing Date, Chadmoore shall not, nor shall it permit any of its
affiliates to, directly or indirectly, encourage (including by way of furnishing
information), solicit, initiate, participate in or otherwise be a party to any
discussions or negotiations with any Person concerning any transaction that
constitutes, or may reasonably be expected to lead to, any Proposal. Neither the
Board of Directors of Chadmoore nor any committee thereof shall (a) withdraw or
modify, or propose to withdraw or modify, in a manner adverse to Nextel, the
approval or recommendation by the Board of Directors of Chadmoore of this
Agreement or (b) approve or recommend, or propose to approve or recommend, any
Proposal. Notwithstanding the foregoing, nothing contained in this Agreement
shall prevent the Board of Directors of Chadmoore from furnishing information
to, or entering into discussions or negotiations with, any unsolicited Person or
taking any action described in clauses (a) and (b) of the preceding sentence, if
and only to the extent that the Board of Directors of Chadmoore shall have
determined in good faith, after receiving advice of its outside counsel, that
such action would be required under applicable law in the exercise of its
fiduciary duties. Chadmoore will immediately notify Nextel if any such inquiries
or proposals are received by, any such information is requested from, or any
such negotiations or discussions are sought to be initiated or continued with,
Chadmoore. As used in this Agreement, "Proposal" shall mean any proposal or
offer from any Person relating to any acquisition (or sublease, as the case may
be) of the Assets or the Business or a merger, share exchange or other business
combination involving Chadmoore or any proposal or offer to acquire in any
manner a substantial equity interest in Chadmoore.

the time such updated information is so provided. Thereafter, to the Closing,
Chadmoore shall notify Nextel in writing of any changes or supplements to the
updated information needed to make such information correct and complete at all
times to the Closing. It is agreed that the furnishing of such corrected and
supplemental information, in and of itself, shall not create any presumption
that such information constitutes or evidences the existence of a material
change or any breach or violation by Chadmoore of any provision of this
Agreement.

    Section 4.11   Loan Documentation. Subject to the consent of Chadmoore's
lenders (if necessary), Chadmoore will execute and deliver any documents

and deliver, or cause to be executed and delivered, to Nextel such deeds,
assignments, bills of sale, consents and other instruments in addition to those
required by this Agreement, in form and substance satisfactory to Nextel, and
take all such other actions, as Nextel may reasonably deem necessary or
desirable to implement any provision of this Agreement or to more effectively
transfer, convey and assign to Nextel or Acquisition Sub good and marketable
title to, and to put Nextel or Acquisition Sub in actual possession and
operating control of, all of the Acquired Assets, free and clear of all Liens,
except for Permitted Liens including, without limitation, the Channels not

effective as promptly as practicable, and shall use its commercially reasonable
efforts to take any action required to be taken to comply in all material
respects with any applicable federal or state securities laws in connection with
the issuance of Nextel Common Stock; except that such covenant of Nextel is
made, as to those portions of the Registration Statement containing or required
to contain Chadmoore Information, assuming and relying on timely and full
compliance with Section 4.04.

            (b) Nextel shall use its commercially reasonable efforts so that the
information included in the Registration Statement, shall not, at the time the
Registration Statement is declared effective, at the time the proxy
statement/prospectus contained therein is first mailed to Chadmoore's
shareholders, or at the time of the meeting of the shareholders of Chadmoore to
approve the transactions contemplated by this Agreement, contain any untrue
statement of a material fact, omit to state any material fact required to be
stated therein, or omit to state any material fact necessary in order to make
the statements therein not misleading; except that such covenant of Nextel is
made, as to those portions of the Registration Statement containing or required
to contain Chadmoore Information, assuming and relying on timely and full
compliance with Section 4.04. If at any time prior to the Closing Date any event
or circumstance should come to the attention of Nextel which is required to be
set forth in an amendment or supplement to the Registration Statement, Nextel
will use its commercially reasonable efforts to appropriately amend or
supplement the Registration Statement. An

                                      -26-
<PAGE>

amendment or supplement may be accomplished, to the extent permitted by law,
rule or regulation, by including such information in a filing under the Exchange
Act that is incorporated by reference into the Registration Statement. The
Registration Statement and all other documents required to be filed by Nextel
with the SEC in connection with the transactions contemplated herein will comply
as to form and substance in all material respects with the applicable
requirements of the Securities Act and the rules and regulations thereunder and

efforts to file all reports required to be filed by it under the Securities Act
or the Exchange Act and the rules and regulations adopted by the SEC thereunder
and shall use all reasonable efforts to take such further action as may be
necessary to ensure that the requirements of Rule 144(c) under the Securities
Act are satisfied such as to enable any "affiliates" of Chadmoore (for purposes
of Rule 145 under the Securities Act) to offer or sell the shares of Nextel
Common Stock received by them under this Agreement pursuant to paragraph (d) of
Rule 145 (subject to compliance with the provisions of paragraphs (e), (f) and
(g) of Rule 144).

    Section 5.04 Funding of Chadmoore Operations. On or about the Signing Date
but not later than August 25, 2000, Nextel will cause a third-party lender to,
or if such arrangements cannot be concluded, cause a wholly owned subsidiary of

reasonable efforts to document such terms as soon as practicable after the
Signing Date. If this Agreement is terminated pursuant to Article 9, the
aggregate amount of advances made as contemplated by this Section 5.04 (the
"Advances") shall become due and payable with interest within 180 days of such
termination. Interest will accrue on a daily basis from the date of such
termination on the unpaid principal amount outstanding pursuant to this Section
5.04, at a rate per annum equal to the Prime Rate. For purposes of this
Agreement, "Prime Rate" means the "Prime Rate" as reported by The Wall Street
Journal in its column entitled "Money Rates." Any fees or interest charged by a
third-party lender in the period prior to the Closing or the termination of this
Agreement shall be paid by Acquisition Sub or by another subsidiary of Nextel.

<PAGE>

            (a) Both immediately before and after the Closing, Nextel shall
control Acquisition Sub within the meaning of Section 368(c) of the Code.

            (b) Except for fees and interest paid to Lender, Nextel and
Acquisition Sub shall pay their expenses incurred in connection with the
Reorganization and this Agreement, and not those of Chadmoore (or any other
shareholder, officer, director or other Person affiliated with Chadmoore) .

            (c) Following the transaction, Acquisition Sub (or a corporation
directly or indirectly controlled by a Acquisition Sub as contemplated under

of the Assets to provide mobile communication services in the active conduct of
a trade or business.

            (d) There is no plan or intention for Nextel, Acquisition Sub or any
Person related (as defined in Treasury Regulations Section 1.368-1(e)(3)) to

proprietary interest in Chadmoore in the transaction through any transaction,
agreement or arrangement with any other Person.

            (e) Neither Nextel nor Acquisition Sub has a plan or intention to
sell or otherwise dispose of any of the Assets, except the ordinary course of
business or transfers described in Section 368(a)(2)(C) of the Code.

of Chadmoore in connection with the Reorganization.

            (i) Following the transaction, Acquisition Sub will not issue
additional shares of its securities that would result in Nextel losing control
of Acquisition Sub within the meaning of Section 368(c) of the Code.

            (j) Unless otherwise required by law, Nextel and Acquisition Sub
shall not take any position on their tax returns inconsistent with treatment of
the purchase and sale of Assets hereunder as a reorganization within the meaning
of Section 368(a)(1)(C) of the Code.

    Section 5.06   COBRA Requirements. To the extent required by Proposed
Treasury Regulation Section 54.4980B-9 (as amended or finalized from time to
time), in the event that Chadmoore ceases to maintain any group health plan for
any employee in connection with the events contemplated in this Agreement,
Nextel agrees that, effective as of the later of the Closing Date of the date
that Chadmoore ceases to provide any group health plan to any employee, Nextel
will have the obligation to make COBRA continuation coverage available to those
individuals who are "M&A qualified beneficiaries" (as defined in the
Regulations) with respect

                                      -28-

Nextel shall have the right at its discretion to assume Chadmoore's group health
plan(s) in connection with satisfying any obligations that it may have under
Code Section 4980B with respect to the former employees of Chadmoore. In the
event that Nextel chooses to assume Chadmoore's group health plan(s), Chadmoore
agrees to take all reasonable actions requested by Nextel in order to effectuate
such assumption.

    Section 5.07   Standstill. From the Signing Date until the Closing Date,
neither Nextel nor any affiliates of Nextel, acting on its behalf or in concert
with it, will directly or indirectly (a) acquire, or offer, propose or agree to

Chadmoore notes), or (b) participate in or encourage the formation of any
partnership, syndicate or other group which owns or seeks or offers to acquire
beneficial ownership of, any securities of Chadmoore (including any Chadmoore
notes).

<PAGE>

hereby; (v) any and all actions, suits, proceedings, claims, demands,

            (b) Each of Nextel and Acquisition Sub covenants and agrees, jointly
and severally, to indemnify and save harmless Chadmoore and its affiliates from

perform any covenants or other agreement on the part of Nextel or Acquisition
Sub, as the case may be, contained in this Agreement or in any other instrument
delivered pursuant to this Agreement; or (iii) any failure of any designee of
Nextel or Acquisition Sub, as the case may be, hereunder to promptly terminate
any application pending before the FCC for the transfer of any SMR License, or

terminated in accordance with its terms prior to Closing.

            (c) The obligations of any indemnifying party under this Section

the following terms and conditions:

                (i) Any party against whom any Third-Party Claim is asserted
will give the party or parties required to provide indemnity hereunder written
notice of any such Third-Party Claim promptly after learning of such Third-Party
Claim, and the indemnifying party may at their or its option undertake the
defense thereof by representatives of their or its own choosing. Failure to give
prompt notice of a Third-Party Claim hereunder shall not affect any indemnifying
party obligations under this Section 6.06, except to the extent any such
indemnifying party is materially prejudiced by such failure to give prompt
notice. If all or any indemnifying party or parties, within thirty (30) days
after notice of any such Third-Party Claim, or such shorter period as is
reasonably required, fails to assume the defense of such Third-Party Claim, the
indemnified party shall have the sole right thereafter to undertake the defense,
compromise or settlement of such Third-Party Claim on behalf of and for the
account and risk, and at the expense, of the indemnifying party or parties, as
the case may be; and

                (ii) Anything in this Section 6.06 to the contrary
notwithstanding, the indemnifying party or parties shall not enter into any
settlement or compromise of any action, suit or proceeding or consent to the
entry of any judgment (A) which does not include as an unconditional term
thereof the delivery by the claimant to the indemnified party of a written
release from all liability in respect of such action, suit or proceeding, or (B)

indemnified party, which consent shall not be unreasonably withheld.

warranties set forth in this Agreement shall not survive the Closing. Except for
the right to make claims

                                      -31-

legally bound hereby, the parties hereto agree as follows:

                              ARTICLE I
                  AMOUNTS AND TERMS OF THE ADVANCES

     1.1  The Advances.  During the eighteen (18) month period (the "Advance
          ------------
Period") commencing on the Effective Date, Lender shall, upon the terms and
conditions hereinafter set forth, make certain advances (the "Advances") to
Borrower upon the request of Borrower, subject to the limitations set forth
in Sections 1.2 and 1.3 below.

     1.2  Aggregate Limitation on Advances.  Lender shall not be obligated to
          --------------------------------
make any Advance under this Agreement if such Advance would cause the aggregate
outstanding Advances extended to Borrower during the Advance period to exceed
Three Hundred Thousand Dollars ($ 300, 000).

     1.3  Reasonable Business Purposes.  Advances shall be permitted pursuant
          ----------------------------
to this Agreement only for the following purposes: (a) to establish and
operate a medical practice concentrating in Nephrology; (b) to provide the
working capital necessary to employ such

<PAGE>

physicians from time to time; and (c) to purchase or lease such real property,
equipment and supplies necessary to the operation of a medical practice.

    1.4  Making the Advances.  Each Advance shall be made upon at least
         -------------------
seventy-two (72) hours prior written notice from Borrower to Lender,
specifying the date on which such Advance is requested to be made and the
amount of such Advance. Within seventy-two (72) hours of the written notice,
or on the date when the Advance is to be made, and upon fulfillment and the
continued satisfaction of the applicable conditions set forth in Article II
below, Lender shall tender the Advance to Borrower, in same day funds, at
the address for Borrower referred to in Section 7.2 below.  Each Advance made
by Lender shall serve to reduce the total amount which Lender is obligated to
advance under Section 1.2 above.

     1.5  Interest.  Interest shall accrue on a monthly basis on each Advance
          --------
made by Lender, at a rate equal to the lesser of the "Prime Rate" as published
by the Wall Street Journal, plus one percent (1%) per annum or the maximum
amount permitted by Georgia law, with interest calculated as of the date on
which each Advance is made to Borrower.

     1.6  Payments of Principal and Interest.  Subject to the provisions set
          ----------------------------------
forth in Section 1.7 below, (a) interest shall accrue but not be paid during
the Advance Period, and (b) principal and the accrued but unpaid interest
shall be payable from Practice Proceeds.  The term "Practice Proceeds" shall
mean the amount calculated by subtracting physicians' base salaries,
professional malpractice insurance costs and practice overhead costs from
practice collections.

     In the event of a termination for any reason of the Employment Agreement
executed this date between South Georgia Nephrology, P.C. and Andrew Queler or
a Transfer Event triggering the transfer of Andrew Queler's shares of stock
in South Georgia Nephrology, P.C. under the Stock Transfer Restriction
Agreement also executed this date, Andrew Queler, personally and individually,
his heirs and administrators, shall be relieved of all obligations under this
Loan and Security Agreement including the obligation of repayment.  Lender
agrees to indemnify and hold harmless Andrew Queler, in his individual
capacity, his heirs and administrators, from any demands to collect repayments
pursuant to this Loan and Security Agreement.  Indemnification shall include
the defense of any claim for repayment as well as payment of any debt,
obligation, compromise, judgment or renovation of said debt.

     1.7  Prepayments.  Any voluntary prepayments shall be treated as first
          -----------
reducing the amount of accrued but unpaid interest on previously extended
Advances and thereafter, as a prepayment with respect to the then outstanding
principal balance of such Advances. All such prepayments may be made in whole
or in part without premium or penalty of any kind. Borrower may not re-borrow
any amounts prepaid in accordance with the terms of this Agreement.

     1.8  Promissory Note.  Payment of principal and interest shall be in
          ---------------
accordance with the terms and conditions of the Promissory Note (the "Note"),
a copy of which is attached

                                       2

<PAGE>

hereto as Exhibit A and incorporated herein by this reference.  The Note shall
be executed by Borrower, shall evidence the indebtedness resulting from the
Advances made by Lender to Borrower, and shall be delivered to Lender pursuant
to Article II below.  The last installment of principal and interest to be
paid by Borrower hereunder shall be in an amount necessary to repay in full
all Advances together with accrued interest on any and all principal amounts
remaining unpaid under the Note.

     executed by Borrower as "Debtor" and naming Lender as the "Lender" with
