                  (a)      Section 2.01(f) of the Loan Agreement is hereby
                           amended to add the following proviso at the end
                           thereof:

                           "; provided, however, that the payments of principal
                           due on the Payment Date closest to June 30, 2001 and
                           on the Payment Date closest to September 30, 2001 may
                           be deferred and shall be payable on the earliest of
                           (i) December 31, 2001, (ii) the prepayment of the
                           Loans pursuant to Section 2.02(e) upon the closing of
                           the transactions contemplated under the Acquisition
                           Agreement, or (iii) at the option of Lender, upon the
                           occurrence of an Event of Default; provided, further,
                           that payments of accrued and unpaid interest shall be

                           Payment  Date closest to June 30, 2001 and the
                           Payment Date closest to September 30, 2001."

                  (b)      The Loan Agreement is hereby amended to add a new
                           Section 2.06 to read in its entirety as follows:

                           "2.05 Deferral Fee. In partial consideration for
                           Lender's agreement to permit the deferral of the
                           payments of principal described in Section 2.01(f),
                           Chadmoore will pay to Lender a fee (the "Deferral
                           Fee") in the amount of One Million Dollars
                           ($1,000,000) which shall be payable on the earliest
                           of (i) December 31, 2001, (ii) the prepayment of the
                           Loans pursuant to Section 2.02(e) upon the closing of
                           the transactions contemplated under the Acquisition
                           Agreement, or (iii) at the option of Lender, upon the
                           occurrence of an Event of Default. The Deferral Fee
                           shall be deemed fully earned whether or not the
                           payment due on the Payment Date closest to September
                           30, 2001 is actually deferred."

                  (c)      The last sentence of Section 7.02 of the Loan
                           Agreement is hereby amended to read in its entirety
                           as follows:

                           "Notwithstanding the foregoing set forth in this
                           Section 7.02, until the termination of the
                           Acquisition Agreement for any reason, compliance with
                           the covenants set forth in this Section 7.02 is
                           waived."

                  (d)      Section 9.01 of the Loan Agreement is hereby amended
                           to amend Section 9.01(m) to read in its entirety as
                           follows:

                           "(m) The Acquisition Agreement shall have been
                           terminated for any reason."

         3.       Condition to Effectiveness.   The Amendment shall be effective
as of the date hereof, upon the satisfaction of the following conditions no
later than the date hereof:

                  (a)      the delivery to Lender of this Amendment duly
                           executed by each Borrower;

                  (b)      the delivery to Borrower of this Amendment duly
                           executed by Lender;

                  (c)      the delivery to Lender of copies, certified by the
                           Secretary of Chadmoore, as of the date hereof, of
                           Chadmoore's corporate resolutions authorizing the
                           execution and delivery of this Amendment; and

                  (d)      the delivery to Lender of a letter of credit issued
                           by a bank satisfactory to Lender in the form of
                           Exhibit A hereto.

         4.       Release.

                  (a)      Chadmoore, on behalf of itself, and its respective
                           present and former officers, directors, employees,
                           affiliates, subsidiary corporations or companies,
                           agents, attorneys, investors, shareholders, partners,
                           members, administrators, predecessor and successor
                           entities, and assigns, hereby fully and forever
                           release and discharge the Lender and its respective
                           present and officers, directors, employees,
                           affiliates, subsidiary corporations or companies,
                           agents, attorneys, investors, shareholders, partners,
                           members, administrators, participants,

                           predecessor and successor entities, and loan
                           participants and assigns, of and from any claim,
                           damages, duty, obligation or cause of action relating
                           to any matters of any kind that any of them may
                           possess arising from any omissions, acts or facts
                           that have occurred up until and including the date
                           hereof, of every nature, kind and description
                           whatsoever, whether known or unknown, choate or
                           inchoate, direct or indirect, and whether suspected
                           or unsuspected, either at law, in equity or
                           otherwise, which may have arisen under or by virtue
                           of the laws of any jurisdiction and which arise from
                           or in connection with or relating in any way to the
                           Loan Agreement, the Operative Documents or the
                           transactions contemplated thereby.

                  (b)      Waiver of California Civil Code Section 1542. Section
                           1542 of the California Civil Code provides as
                           follows:

                           "A general release does not extend to claims which
                           the creditor does not know or suspect to exist in his
                           favor at the time of executing the release, which if
                           known by him must have materially affected his
                           settlement with the debtor."

                           Chadmoore expressly waives the provisions of Section
                           1542 of the California Civil Code and elect to and do
                           assume all risk for claims heretofore arising, known
                           or unknown, suspected to exist or not suspected to
                           exist, as described above, and voluntarily and
                           expressly release the Lender from all liability on
                           claims arising out of such matters as described
                           above.

         5.       Exculpation. Chadmoore acknowledges and agrees that Lender is
entering into this Amendment as an accommodation to Chadmoore and that neither
Lender nor any Indemnified Party (as defined below) shall be liable for any
action taken or omitted to be taken by it or them in connection with any
exercise of Lender's remedies under the Loan Agreement regardless of the effect
of such exercise on Chadmoore or on the Acquisition Agreement and the
transactions contemplated thereunder.

         6.       Expenses; Indemnification. Chadmoore shall pay on demand (i)
all reasonable fees and expenses, including reasonable attorneys' fees and
expenses, incurred by Lender in connection with the preparation, execution and
delivery of, and the exercise of its duties under, this Amendment, the
transactions contemplated hereby and under the Acquisition Agreement and all
other matters related in any way to the acquisition of the assets of Chadmoore
by Nextel, whether or not such acquisition is consummated, (ii) all reasonable
fees and expenses, including reasonable attorneys' fees and expenses, incurred
by Lender in connection with the preparation, execution and delivery of
amendments and waivers hereunder and (iii) all reasonable fees and expenses,
including reasonable attorneys' fees and expenses, incurred by Lender in
connection with the enforcement or attempted enforcement of Loan Agreement or
any of the Obligations or in preserving any of Lender's rights and remedies
(including, without limitation, all such fees and expenses incurred in
connection with any "workout" or restructuring affecting the Operative Documents
or the Obligations or any bankruptcy or similar proceeding involving any
Borrower or any of its Affiliates). Chadmoore shall indemnify, reimburse and
hold Lender, each of Lender's members, and each of their respective successors,
assigns, agents, officers, directors, shareholders, servants, agents,
participants and employees (each, an "Indemnified Party") harmless from and
against all liabilities, losses, damages, actions, suits, demands, claims of any
kind and nature (including claims relating to environmental discharge, cleanup
or compliance), all costs and expenses whatsoever to the extent they may be
incurred or suffered by such indemnified party in connection therewith
(including reasonable attorneys' fees and expenses), fines, penalties (and other
charges of applicable governmental authorities) (each, a "Claim"), directly or
indirectly relating to or arising out of any matter relating to the subject of
this Amendment, the acquisition of the assets of Chadmoore by

                                      -3-
<PAGE>
Nextel, whether or not such acquisition is consummated and however such
acquisition may be structured. The foregoing indemnity shall cover, without
limitation any Claim for tortious interference with contract or similar matter.
Notwithstanding the foregoing, Chadmoore shall not indemnify an Indemnified
Party for any liability incurred by an Indemnified Party as a result of such
Indemnified Party's gross negligence or willful misconduct. Such indemnities
shall continue in full force and effect, notwithstanding the expiration or
termination of the Loan Agreement. Upon an Indemnified Party's written demand,
Chadmoore shall assume and diligently conduct, at its sole cost and expense, the
entire defense of such Indemnified Party, using counsel reasonably acceptable to
such indemnitee against any indemnified Claim. Chadmoore shall not settle or
compromise any Claim against or involving an Indemnified Party without first
obtaining such Indemnified Party's and Lender's written consent thereto, which
consent shall not be unreasonably withheld. If an Indemnified Party elects to
assume its own defense in connection with an indemnified Claim, then such
Indemnified Party shall not settle or compromise such Claim without first
obtaining Chadmoore's written consent thereto, which consent shall not be
unreasonably withheld, provided that if Chadmoore does not consent thereto, then
Chadmoore shall post security or a bond in the amount of such Claim for the
benefit of the Indemnified Party.

         7.       Effect of Amendment. On and after the date hereof, each
reference to the Loan Agreement in the Loan Agreement or in any other document
shall mean the Loan Agreement as amended by this Amendment. The execution,
delivery and effectiveness of this Amendment shall not operate as a waiver of
any right, power, or remedy of Lender, nor constitute a waiver of any provision
of the Loan Agreement which is not specifically waived hereunder. Upon the
termination of any period during which a waiver was effective, the provision so
waived shall be reinstated in full force and effect. Lender retains its rights
to exercise its remedies under the Loan Agreement or otherwise upon the
occurrence of any Event of Default under the Loan Agreement.

         8.       Representations and Warranties. Each Borrower hereby
represents and warrants to Lender that:

                  (a)      such Borrower is a corporation or limited liability
                           company duly organized, validly existing and in good
                           standing under the laws of its state of incorporation
                           or formation;

                  (b)      such Borrower has the full corporate or company
                           power, authority and legal right and has obtained all
                           necessary approvals, consents and given all notices
                           to execute and deliver this Amendment and perform the
                           terms thereof;

                  (c)      there is no action, proceeding or claim pending or,
                           insofar as such Borrower knows, threatened against
                           such Borrower or any of its subsidiaries before any
                           court or administrative agency which might have a
                           materially adverse effect on the business, condition
                           or operations of such Borrower;

                  (d)      this Amendment has been duly executed and delivered
                           by such Borrower and constitutes the valid, binding
                           and enforceable obligation of such Borrower;

                  (e)      Chadmoore has delivered to Lender a true and correct
                           copy of the Acquisition Agreement;

                  (f)      After giving effect to the waivers set forth in this
                           Fifth Amendment, no Default or Event of Default under
                           the Loan Agreement has occurred which has not been
                           waived; and

                                      -4-
<PAGE>
                  (g)      Schedule 1 hereto constitutes a complete and accurate
                           list of all deposit accounts, securities accounts or
                           other accounts holding cash, cash equivalents or
                           other marketable securities of Chadmoore.

         9.       Post Closing Covenants.

                  (a)      Pursuant to Section 4 of the Security Agreement,
                           Chadmoore shall use its good faith efforts to deliver
                           to Lender by July 10, 2001, and shall deliver in any
                           case by July 30, 2001, instruments intended to
                           perfect Lender's security interest in the accounts
                           listed on Schedule 1 hereto in the forms attached as
                           Exhibits B and C hereto or such other forms which are
                           acceptable to Lender. The failure to comply with the
                           covenant set forth in this Section 9(a) shall
                           constitute an Event of Default under the Loan
                           Agreement.

                  (b)      Chadmoore, in cooperation with Nextel, shall place on
                           file with the FCC no later than July 6, 2001, the
                           application seeking assignment of substantially all
                           of the 800 and 900 MHz SMR licenses to Nextel under
                           the Acquisition Agreement. The failure to comply with
                           the covenant set forth in this Section 9(b) shall
                           constitute an Event of Default under the Loan
                           Agreement.

         10.      Draws under Letter of Credit. Lender agrees that it will not
draw under the letter of credit delivered pursuant to this Amendment prior to
the earlier to occur of (i) December 31, 2001, or (ii) the occurrence of an
Event of Default.

         11.      Full Force and Effect.  Except as amended above, the Loan
Agreement remains in full force and effect.

         12.      Headings. Headings in this Amendment are for convenience of
reference only and are not part of the substance hereof.

         13.      Governing Law. This Amendment shall be governed by and
construed in accordance with the laws of the State of California without
reference to conflicts of law rules.

         14.      Counterparts. This Amendment may be executed in any number of
identical counterparts, any set of which signed by all of the parties hereto
shall be deemed to constitute a complete, executed original for all purposes.

("Chadmoore"), the Chadmoore Subsidiaries (together with Chadmoore and their
respective successors and assigns, collectively, "Borrowers" and, individually,
"Borrower"), and BARCLAYS BANK PLC ("Bank").

         WHEREAS, Borrowers and Bank are parties to a certain Subordinated
Credit Agreement, dated as of August 31, 2000, and as the same may from time to

         WHEREAS, each capitalized term used herein shall be defined in
accordance with the Credit Agreement;

         NOW, THEREFORE, in consideration of the premises and of the mutual
covenants herein contained and for other valuable considerations, Borrowers and
Bank hereby agree as follows:

1.                Article I of the Credit Agreement is hereby amended to delete
         the definitions of "Obligations" and "Operative Documents" in their

                  "Obligations" shall mean and include the Letter of Credit and
         all Loans, advances, debts, liabilities and obligations, howsoever
         arising, owed by the Borrowers to Bank of every kind and description
         (whether or not evidenced by any note or instrument and whether or not

         under Title 11 of the United States Code (11 U. S. C. Section 101 et
         seq.), as amended from time to time (including post-petition interest)
         and whether or not allowed or allowable as a claim in any such
         proceeding.

         all documentation relating to the Letter of Credit, the Guaranty, the
         Security Agreement, the Subordination Agreement, and all other
         documents, instruments, and agreements executed and delivered in
         connection herewith or therewith or in respect with the closing of the

2.                Article I of the Credit Agreement is hereby amended to add the
         following new definitions thereto:

                  "Advances" shall mean and include all the Obligations

                  "Base Rate Loan" shall mean any Loan hereunder on which
         Borrowers shall pay interest at a rate based on the Adjusted Base Rate.

                  "Eurodollar Loan" shall mean any Loan hereunder on which
         Borrowers shall pay interest at a rate based on the LIBO Rate.

         of credit no. SB00110 in an original face amount not to exceed Two
         Million Seven Hundred Thousand Dollars ($2,700,000) issued by Bank in
         favor of Senior Lender as the same may from time to time be amended,
         restated or otherwise modified or replaced.

                  "Letter of Credit Exposure" shall mean the sum of (a) the
         aggregate undrawn face amount of the Letter of Credit, and (b) the
         aggregate of the draws made on the Letter of Credit that have not been
         reimbursed by Borrowers or converted to a Loan pursuant to Section 2.11
         hereof.

3.                The Credit Agreement is hereby amended to delete Section
         2.01(a) in its entirety, to delete the last sentence of Section 2.01(d)
         and to substitute in place thereof, and to delete Section 2.01(f) in
         its entirety and to substitute in place thereof, respectively, the

                  2.01.    Credit Facility; Notes.
                           ----------------------

                  (a) Availability. On the terms and subject to the conditions
         hereof, Bank agrees to make Loans to the Borrowers up to an aggregate
         principal amount of (i) Thirty Million Nine Hundred Thousand Dollars
         ($30,900,000) minus (ii) the original face amount of the Letter of
         Credit.

                  (d) No subsequent Loan Request (other than draws under the
         Letter of Credit described under Section 2.11) shall request a Loan of
         more than the sum of $900,000 plus any fees or interest then due
         hereunder or which are reasonably expected to become due within 30 days
         thereafter.

<PAGE>
                  (e) Frequency. Loans (other than Loans under Section 2.11)
         shall be made to the Borrowers not more than monthly, on or before the
         fifth Business Day of a calendar month.

4.                The Credit Agreement is hereby amended to delete Section
         2.06(a)(ii) and Section 2.06(b), and substitute in place thereof,
         respectively, the following:

                  2.06.    Increased Costs.
                           ---------------

                  (a)      Increased Costs Generally.  If any Change in Law
         shall:

                  (ii) impose on Bank or the London interbank market any other
         condition affecting this Agreement, the Letter of Credit or Eurodollar
         Loans made by such Bank or any participation therein;

         and the result of any of the foregoing shall be to increase the cost to
         such Bank of making or maintaining the Letter of Credit or any
         Eurodollar Loan (or of maintaining its obligation to make any such
         Loan) or to reduce the amount of any sum received or receivable by such
         Bank hereunder (whether of principal, interest or otherwise), then the
         Borrower will pay to such Bank such additional amount or amounts as
         will compensate such Bank, as the case may be, for such additional
         costs incurred or reduction suffered.

                  (b) Capital Requirements. If any Bank or Issuing Bank
         reasonably determines that any Change in Law regarding capital
         requirements has or would have the effect of reducing the rate of
         return on such Bank's capital or on the capital of such Bank's holding
         company, if any, as a consequence of this Agreement, the Letter of
         Credit or the Loans made by such Bank, to a level below that which such
         Bank or such Bank's holding company could have achieved but for such
         Change in Law (taking into consideration such Bank's policies and the
         policies of such Bank's holding company with respect to capital
         adequacy), then from time to time the Borrower will pay to such Bank,
         such additional amount or amounts as will compensate such Bank, or such
         Bank's holding company, for any such reduction suffered.

5.                The Credit Agreement is hereby amended by adding the following
         new Section 2.11 thereto:

                  2.11.    Letter of Credit.
                           ----------------

                  (a) Subject to the terms and conditions of this Agreement,
         Bank shall issue the Letter of Credit for the account of Chadmoore.

                  (b) In respect of the Letter of Credit and the drafts
         thereunder, if any, Borrowers agree to pay to Bank, (i) a Letter of
         Credit fee of $1000, which shall be paid on the date that the Letter of
         Credit is issued; (ii) a commission of 4.5% per annum of the undrawn
         portion of the Letter of Credit; and (iii) such other issuance,
         amendment, negotiation, draw, acceptance, telex, courier, postage and
         similar transactional fees as are generally charged by Bank under its
         fee schedule as in effect from time to time.

                                      -3-
<PAGE>
                  (c) Whenever the Letter of Credit is drawn, the amount drawn
         shall be a Loan to Borrowers subject to the provisions of this Section
         2 and shall be evidenced by the Note. Each such Loan shall be deemed to
         be a Base Rate Loan unless otherwise requested by and available to
         Borrowers hereunder. Bank is hereby authorized to record on its records
         relating to the Note the amounts paid on the Letter of Credit.

                  (d) If the maturity of the Loans shall be accelerated,
         Borrowers shall immediately deposit with Bank, as security for
         Borrowers' obligations to reimburse Bank for the Letter of Credit, if
         then outstanding, cash equal to the Letter of Credit Exposure. Bank is
         hereby authorized, at its option, to deduct any and all such amounts
         from any deposit balances then owing by Bank to or for the credit or
         account of any Borrower or Guarantor, as security for Borrowers'
         obligations to reimburse Bank for amounts paid under the Letter of
         Credit.

6.                The Credit Agreement is hereby amended to add the following
         new Section 10.17 thereto:

Each request by Borrowers for the making, conversion or continuation of any Loan
shall be deemed to be a joint and several request by all Borrowers. Each
Borrower hereby authorizes any other Borrower to request a Loan hereunder and
agrees that it is receiving or will receive a direct pecuniary benefit therefor.
Each Borrower acknowledges and agrees that Bank is entering into this Agreement
at the request of each Borrower and with the full understanding that each
Borrower is and shall remain fully liable, jointly and severally, for the
payment in full of the Obligations.

7.       Concurrently with the execution of this Amendment,  Borrowers shall:

                  (a) deliver an opinion of its counsel in form and substance
         satisfactory to Bank; and

                  (b) cause each Guarantor to consent and agree to and
         acknowledge the terms of this Amendment.

8.                Borrowers hereby represent and warrant to Bank that (a)
         Borrowers have the legal power and authority to execute and deliver
         this Amendment, (b) the officers executing this Amendment have been
         duly authorized to execute and deliver the same and bind Borrowers with
         respect to the provisions hereof, (c) the execution and delivery hereof
         by Borrowers and the performance and observance by Borrowers of the
         provisions hereof do not violate or conflict with the organizational
         agreements of Borrowers or any law applicable to Borrowers or result in
         a breach of any provision of or constitute a default under any other
         agreement, instrument or document binding upon or enforceable against
         Borrowers, (d) no Default or Event of Default exists under the Credit
         Agreement, nor will any occur immediately after the execution and
         delivery of this Amendment or by the performance or observance of any
         provision hereof, (e) Borrowers are not aware of any claim or offset
         against, or defense or counterclaim to, any of Borrowers' obligations
         or liabilities under the Credit Agreement or any Related Writing and
         (f) this Amendment

                                      -4-
<PAGE>
         constitutes a valid and binding obligation of Borrowers in every
         respect, enforceable in accordance with its terms.

9.                Borrowers, by signing below, hereby waive and release Bank and
         its respective directors, officers, employees, attorneys, affiliates
         and subsidiaries from any and all claims, offsets, defenses and
         counterclaims of which Borrowers are aware, such waiver and release
         being with full knowledge and understanding of the circumstances and
         effect thereof and after having consulted legal counsel with respect
         thereto.

10.               Each reference that is made in the Credit Agreement or any
         Related Writing to the Credit Agreement shall hereafter be construed as
         a reference to the Credit Agreement as amended hereby. Except as herein
         otherwise specifically provided, all provisions of the Credit Agreement
         shall remain in full force and effect and be unaffected hereby. This
         Amendment is a Related Writing as defined in the Credit Agreement.

11.               This Amendment may be executed in any number of counterparts,
         by different parties hereto in separate counterparts and by facsimile
         signature, each of which when so executed and delivered shall be deemed
         to be an original and all of which taken together shall constitute but
         one and the same agreement.
