Amended and Restated Guaranty

As of April 12, 2000, the undersigned, for value received,
unconditionally and absolutely guarantees to Comerica Bank - California
("Bank"), a California banking corporation, payment when due, whether by
stated maturity, demand, acceleration or otherwise, of all existing and
future indebtedness ("Indebtedness") to the Bank of Datron World
Communications Inc., a California corporation ("DWC"), and Datron/Transco
Inc., a California corporation ("DT", and together with DWC, "Borrower").
Indebtedness includes without limit any and all obligations or liabilities
of the Borrower to the Bank, whether absolute or contingent, direct or
indirect, voluntary or involuntary, liquidated or unliquidated, joint or
several, known or unknown; any and all indebtedness, obligations or
liabilities for which Borrower would otherwise be liable to the Bank were
it not for the invalidity, irregularity or unenforceability of them by
reason of any bankruptcy, insolvency or other law or order of any kind, or
for any other reason; all amendments, modifications, renewals and/or
extensions of the above; and all costs of collecting Indebtedness,
including, without limit, attorney fees.  Any reference in this Guaranty to
attorney fees shall be deemed a reference to reasonable fees, charges,
costs and expenses of both in-house and outside counsel and paralegals,
whether or not a suit or action is instituted, and to court costs if a suit
or action is instituted, and whether attorney fees or court costs are
incurred at the trial court level, on appeal, in a bankruptcy,
administrative or probate proceeding or otherwise.  All costs shall be
payable by the undersigned when incurred by the Bank, without demand, and
if not paid within ten (10) business days of when first due, shall bear
interest at the default rate of interest applicable to the Indebtedness
under Borrower's agreements with Bank until paid in full, but not in excess
of the maximum rate permitted by law.

1.   LIMITATION: The total obligation of the undersigned under this
   Guaranty shall include, IN ADDITION TO the principal guaranteed, all
   interest on the principal amount, and all costs incurred by the Bank in
   collection efforts against the Borrower and/or the undersigned or otherwise
   incurred by the Bank in any way relating to the Indebtedness, or this
   Guaranty, including without limit attorney fees.  The undersigned agrees
   that (a) this limitation shall not be a limitation on the amount of
   Borrower's Indebtedness to the Bank; (b) any payments by the undersigned
   shall not reduce the maximum liability of the undersigned under this
   Guaranty unless written notice to that effect is actually received by the
   Bank at, or prior to, the time of the payment; and (c) the liability of the
   undersigned to the Bank shall at all times be deemed to be the aggregate
   liability of the undersigned under this Guaranty and any other guaranties
   previously or subsequently given to the Bank by the undersigned and not
   expressly revoked, modified or invalidated in writing.

2.   NATURE OF GUARANTY:  This is a continuing Guaranty of payment and not
   of collection, and remains effective whether the Indebtedness is from time
   to time reduced and later increased or entirely extinguished and later
   reincurred.  The undersigned delivers this Guaranty based solely on the
   undersigned's independent investigation of (or decision not to investigate)
   the financial condition of Borrower and is not relying on any information
   furnished by the Bank.  The undersigned assumes full responsibility for
   obtaining any further information concerning the Borrower's financial
   condition, the status of the Indebtedness or any other matter which the
   undersigned may deem necessary or appropriate now or later.  The
   undersigned knowingly accepts the full range of risk encompassed in this
   Guaranty, which risk includes, without limit, the possibility that Borrower
   may incur Indebtedness to the Bank after the financial condition of the
   Borrower, or the Borrower's ability to pay debts as they mature, has
   deteriorated.

3.   APPLICATION OF PAYMENTS:  The undersigned authorizes the Bank, either
   before or after termination of this Guaranty, without notice to or demand
   on the undersigned and without affecting the undersigned's liability under
   this Guaranty, from time to time to: (a) apply any security and direct the
   order or manner of sale; and (b) apply payments received by the Bank from
   the Borrower to any indebtedness of the Borrower to the Bank, in such order
   as the Bank shall determine in its sole discretion, whether or not this
   indebtedness is covered by this Guaranty, and the undersigned waives any
   provision of law regarding application of payments which specifies
   otherwise.  The undersigned agrees to provide to the Bank copies of the
   undersigned's financial statements upon request.

4.   SETOFF:  The undersigned acknowledges the Bank's right of setoff as to
   any and all deposits and other amounts from time to time in the possession
   of, or owing to the undersigned by, the Bank.  The undersigned further
   assigns to the Bank as collateral for the obligations of the undersigned
   under this Guaranty all claims of any nature that the undersigned now or
   later has (have) against the Borrower (other than any claim under a deed of
   trust or mortgage covering California real property) with full right on the
   part of the Bank, in its own name or in the name of the undersigned, to
   collect and enforce these claims.  The undersigned agrees that no security
   now or later held by the Bank for the payment of any Indebtedness, whether
   from the Borrower, any guarantor, or otherwise, and whether in the nature
   of a security interest, pledge, lien, assignment, setoff, suretyship,
   guaranty, indemnity, insurance or otherwise, shall affect in any manner the
   unconditional obligation of the undersigned under this Guaranty, and the
   Bank, in its sole discretion, without notice to the undersigned, may
   release, exchange, enforce and otherwise deal with any security without
   affecting in any manner the unconditional obligation of the undersigned
   under this Guaranty.  The undersigned acknowledges and agrees that the Bank
   has no obligation to acquire or perfect any lien on or security interest in
   any asset(s), whether realty or personalty, to secure payment of the
   Indebtedness, and the undersigned is not relying upon any asset(s) in which
   the Bank has or may have a lien or security interest for payment of the
   Indebtedness.

5.   OTHER GUARANTORS:  If any Indebtedness is guaranteed by two or more
   guarantors, the obligation of the undersigned shall be several and also
   joint, each with all and also each with any one or more of the others, and
   may be enforced at the option of the Bank against each severally, any two
   or more jointly, or some severally and some jointly.  The Bank, in its sole
   discretion, may release any one or more of the guarantors for any
   consideration which it deems adequate, and may fail or elect not to prove a
   claim against the estate of any bankrupt, insolvent, incompetent or
   deceased guarantor; and after that, without notice to any guarantor, the
   Bank may extend or renew any or all Indebtedness and may permit the
   Borrower to incur additional Indebtedness, without affecting in any manner
   the unconditional obligation of the remaining guarantor(s).  The
   undersigned acknowledges that the effectiveness of this Guaranty is not
   conditioned on any or all of the indebtedness being guaranteed by anyone
   else.

6.   TERMINATION:  The undersigned may not terminate its obligation under
   this Guaranty as to future Indebtedness (except as provided below) by (and
   only by) delivering written notice of termination to an officer of the Bank
   and receiving from an officer of the Bank written acknowledgment of
   delivery; provided, however, the termination shall not be effective until
   the opening of business on the fifth (5th) day ("effective date") following
   written acknowledgment of delivery.  Any termination shall not affect in
   any way the unconditional obligations of the remaining guarantor(s), if
   any, whether or not the termination is known to the remaining guarantor(s).
   Any termination shall not affect in any way the unconditional obligations
   of the terminating guarantor(s) as to any Indebtedness existing at the
   effective date of termination or any Indebtedness created after that
   pursuant to any commitment or agreement of the Bank or pursuant to any
   Borrower loan with the Bank existing at the effective date of termination
   (whether advances or readvances by the Bank after the effective date of
   termination are optional or obligatory), or any modifications, extensions
   or renewals of any of this Indebtedness, whether in whole or in part, and
   as to all of this Indebtedness and modifications, extensions or renewals of
   it, this Guaranty shall continue effective until the same shall have been
   fully paid.  The Bank has no duty to give notice of termination by any
   guarantor(s) to any remaining guarantor(s).  The undersigned shall
   indemnify the Bank against all claims, damages, costs and expenses,
   including, without limit, attorney fees, incurred by the Bank in connection
   with any suit, claim or action against the Bank arising out of any
   modification or termination of a Borrower loan or any refusal by the Bank
   to extend additional credit in connection with the termination of this
   Guaranty.

7.   REINSTATEMENT:  Notwithstanding any prior revocation, termination,
   surrender or discharge of this Guaranty (or of any lien, pledge or security
   interest securing this Guaranty) in whole or in part, the effectiveness of
   this Guaranty, and of all liens, pledges and security interests securing
   this Guaranty, shall automatically continue or be reinstated in the event
   that any payment received or credit given by the Bank in respect of the
   Indebtedness is returned, disgorged or rescinded under any applicable state
   or federal law, including, without limitation, laws pertaining to
   bankruptcy or insolvency, in which case this Guaranty, and all liens,
   pledges and security interests securing this Guaranty, shall be enforceable
   against the undersigned as if the returned, disgorged or rescinded payment
   or credit had not been received or given by the Bank, and whether or not
   the Bank relied upon this payment or credit or changed its position as a
   consequence of it.  In the event of continuation or reinstatement of this
   Guaranty and the liens, pledges and security interests securing it, the
   undersigned agrees upon demand by the Bank, to execute and deliver to the
   Bank those documents which the Bank determines are appropriate to further
   evidence (in the public records or otherwise) this continuation or
   reinstatement, although the failure of the undersigned to do so shall not
   affect in any way the reinstatement or continuation.  If the undersigned
   does not execute and deliver to the Bank upon demand such documents, the
   Bank and each Bank officer is irrevocably appointed (which appointment is
   coupled with an interest) the true and lawful attorney of the undersigned
   (with full power of substitution) to execute and deliver such documents in
   the name and on behalf of the undersigned.

8.   WAIVERS:  The undersigned waives any right to require the Bank to: (a)
   proceed against any person or property; (b) give notice of the terms, time
   and place of any public or private sale of personal property security held
   from the Borrower or any other person, or otherwise comply with the
   provisions of  Section 9-504 of  the California Uniform Commercial Code or
   other applicable Uniform Commercial Code; or (c) pursue any other remedy in
   the Bank's power.  The undersigned waives notice of acceptance of this
   Guaranty and presentment, demand, protest, notice of protest, dishonor,
   notice of dishonor, notice of default, notice of intent to accelerate or
   demand payment of any Indebtedness, any and all other notices to which the
   undersigned might otherwise be entitled, and diligence in collecting any
   Indebtedness, and agrees that the Bank may, once or any number of times,
   modify the terms of any Indebtedness, compromise, extend, increase,
   accelerate, renew or forbear to enforce payment of any or all Indebtedness,
   or permit the Borrower to incur additional Indebtedness, all without notice
   to the undersigned and without affecting in any manner the unconditional
   obligation of the undersigned under this Guaranty.

   The undersigned unconditionally and irrevocably waives each and every
   defense and setoff of any nature which, under principles of guaranty or
   otherwise, would operate to impair or diminish in any way the
   obligation of the undersigned under this Guaranty, and acknowledges
   that each such waiver is by this reference incorporated into each
   security agreement, collateral assignment, pledge and/or other document
   from the undersigned now or later securing this Guaranty and/or the
   Indebtedness, and acknowledges that as of the date of this Guaranty no
   such defense or setoff exists.

   The undersigned understands that, absent this waiver, Bank's election
   of remedies, including but not limited to its decision to proceed to
   nonjudicial foreclosure on any real property securing the Indebtedness,
   could preclude Bank from obtaining a deficiency judgment against
   Borrower and the undersigned pursuant to California Code of Civil
   Procedures Sections 580a, 580b, 580d or 726 and could also destroy any
   subrogation rights which the undersigned has against Borrower. The
   undersigned further understands that, absent this waiver, California
   law, including without limitation, California Code of Civil Procedure
   Sections 580a, 580b, 580d or 726, could afford the undersigned one or
   more affirmative defenses to any action maintained by Bank against the
   undersigned on this Guaranty.

   Although, the intent of the undersigned and the Bank is that California
   law shall apply, the undersigned waives any and all rights and
   provisions of California Code of Civil Procedure Sections 580a, 580b,
   580d and 726, including, but not limited to any provision thereof that:
   (i) may limit the time period for Bank to commence a lawsuit against
   Borrower or the undersigned to collection any Indebtedness owing by
   Borrower or the undersigned to Bank; (ii) may entitle Borrower or the
   undersigned to a judicial or nonjudicial determination of any
   deficiency owed by Borrower or the undersigned to Bank, or to otherwise
   limit Bank's right to collect a deficiency based on the fair market
   value of such real property security; (iii) may limit Bank's right to
   collect a deficiency judgment after a sale of any real property
   securing the indebtedness; (iv) may require Bank to take only one
   action to collect the indebtedness or that may otherwise limit the
   remedies available to Bank to collect the Indebtedness.

   Although, the intent of the undersigned and the Bank is that California
   law shall apply, the undersigned waives all rights and defenses arising
   out of an election of remedies by Bank even though that election of
   remedies, such as a nonjudicial foreclosure with respect to security
   for a guarantee obligation, has destroyed the undersigned's rights of
   subrogation and reimbursement against Borrower by the operation of
   Section 580d of the Code of Civil Procedure or otherwise.

9.   WAIVER OF SUBROGATION:  The undersigned postpones any and all rights
   (whether by subrogation, indemnity, reimbursement, or otherwise) to recover
   from the Borrower any amounts paid by the undersigned pursuant to this
   Guaranty until such time that all Indebtedness has been finally and
   irrevocably paid to Bank.

10.   SALE/ASSIGNMENT:  The undersigned acknowledges that the Bank has the
   right to sell, assign, transfer, negotiate, or grant participations in all
   or any part of the Indebtedness and any related obligations, including,
   without limit, this Guaranty, without notice to the undersigned and that
   the Bank may disclose any documents and information which the Bank now has
   or later acquires relating to the undersigned or to the Borrower in
   connection with such sale, assignment, transfer, negotiation, or grant.
   The undersigned agrees that the Bank may provide information relating to
   this Guaranty or relating to the undersigned to the Bank's parent,
   affiliates, subsidiaries and service providers.

11.   WITHHOLDING TAXES:  All payments to be made by the undersigned under
   this Guaranty shall be made without setoff or counterclaim and without
   deduction for or on account of any present or future withholding or other
   taxes of any nature imposed by any governmental authority or of any
   political subdivision thereof or any federation or organization of which
   such governmental authority may at the time of payment be a member, unless
   the undersigned is compelled by law to make payment subject to such tax.
   In such event, the undersigned shall:  (a)  pay to the Bank for the account
   of the Bank such additional amounts as may be necessary to ensure that the
   Bank receives a net amount equal to the full amount which would have been
   receivable under this Guaranty had payment not been made subject to such
   tax; and (b) send to the Bank such certificates or certified copies of
   receipts as the Bank shall reasonably require as proof of the payment by
   the undersigned of any such taxes payable by the undersigned.  As used
   herein, the terms "tax", "taxes" and "taxation" include all existing taxes,
   levies, imposts, duties, charges, fees, deductions and withholdings and any
   restrictions or conditions resulting in a charge, together with interest
   thereon and fines and penalties with respect thereto, which may be imposed
   by reason of any violation or default with respect to the law regarding
   such tax, assessed as a result of or in connection with the Indebtedness or
   the obligation of the undersigned hereunder, or the payment or delivery of
   funds into or out of any jurisdiction other than the United States (whether
   assessed against Borrower, the undersigned or the Bank).

12.   GENERAL:  This Guaranty constitutes the entire agreement of the
   undersigned and the Bank with respect to the subject matter of this
   Guaranty.  No waiver, consent, modification or change of the terms of the
   Guaranty shall bind any of the undersigned or the Bank unless in writing
   and signed by the waiving party or an authorized officer of the waiving
   party, and then this waiver, consent, modification or change shall be
   effective only in the specific instance and for the specific purpose given.
   This Guaranty shall inure to the benefit of the Bank and its successors and
   assigns and shall be binding on the undersigned and the undersigned's
   heirs, legal representatives, successors and assigns including, without
   limit, any debtor in possession or trustee in bankruptcy for any of the
   undersigned.  The undersigned has knowingly and voluntarily entered into
   this Guaranty in good faith for the purpose of inducing the Bank to extend
   credit or make other financial accommodations to the Borrower.  If any
   provision of this Guaranty is unenforceable in whole or in part for any
   reason, the remaining provisions shall continue to be effective.

13.   GOVERNING LAW AND JURISDICTION:   THIS GUARANTY SHALL BE GOVERNED BY
   AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF
   CALIFORNIA, UNITED STATES OF AMERICA, WITHOUT REGARD TO CONFLICT OF LAWS
   PRINCIPLES; The undersigned hereby irrevocably agrees that any legal
   action, suit, or proceeding against it with respect to its obligations,
   liabilities or any other matter under or arising out of or in connection
   with this Guaranty, the Indebtedness or the transactions or documents
   contemplated hereby or for recognition or enforcement of any judgment
   rendered in any such action, suit or proceeding may be brought in the
   United States Courts or in the courts of the State of California, or in any
   other court having jurisdiction over the subject matter, as the Bank in its
   sole discretion may elect, and, by its execution and delivery of this
   Guaranty, the undersigned hereby irrevocably accepts and submits to the non-
   exclusive jurisdiction of each of the aforesaid courts generally and
   unconditionally with respect to any such action, suit or proceeding for
   itself and in respect of its property.  The undersigned further agrees that
   final judgment against it in any action, suit, or proceeding referred to
   herein shall be conclusive and may be enforced in any other jurisdiction,
   within or outside the United States of America, by suit on the judgment, a
   certified or exemplified copy of which shall be conclusive evidence of the
   fact and of the amount of its indebtedness.  The undersigned further
   irrevocably consents and agrees to the service of any and all legal
   process, summons, notices, and documents out of any of the aforesaid courts
   in any action, suit or proceeding by mailing copies thereof by registered
   or certified mail, postage prepaid, to the undersigned at its address set
   forth in this Guaranty or to any other address of which the undersigned
   shall have given prior written notice to Bank.  The undersigned agrees that
   service upon the undersigned as provided for herein shall constitute valid
   and effective personal service upon the undersigned.  Nothing herein shall,
   or shall be construed so as to, limit the right of the Bank, or any of its
   successors or assigns, to bring actions, suits or proceedings with respect
   to the obligations and liabilities of the undersigned under, or any other
   matter arising out of or in connection with, this Guaranty, the
   Indebtedness or the transactions or documents contemplated hereby, or for
   recognition or enforcement of any judgment rendered in any proceeding, in
   the courts of whatever jurisdiction in which the Indebtedness or the
   obligations or liabilities of the undersigned hereunder may arise or are
   created or in which the assets of the undersigned may be found or as
   otherwise shall seem appropriate to the Bank, or any of its successors or
   assigns, or to affect the right to service of process in any jurisdiction
   in any other manner permitted by law; (c) In addition, the undersigned
   hereby irrevocably and unconditionally waives any objection which it may
   now or hereafter have to the laying of venue of any of the aforesaid
   actions, suits or proceedings arising out of or in connection with this
   Guaranty, the Indebtedness or the transactions contemplated hereby brought
   in any federal or state court situate in the State of California, and
   hereby further irrevocably and unconditionally waives and agrees not to
   plead any claim that any such action, suit or proceeding brought in any
   such court has been brought in an inconvenient forum.

14.   REPRESENTATIONS AND WARRANTIES:

   The undersigned hereby represents and warrants to Bank:

   a.   Undersigned is a corporation duly organized and existing in good
      standing under the laws of  Delaware, is duly qualified and authorized to
      do business in each jurisdiction where the character of its assets or the
      nature of its activities makes such qualification necessary and failure to
      so qualify could have a Material Adverse Effect; execution, delivery and
      performance of this Guaranty, and any other documents and instruments
      required under this Guaranty, are within its corporate powers, have been
      duly authorized, are not in contravention of law or the terms of its
      organizational documents, and do not require the consent or approval of
      any governmental body, agency or authority that has not been obtained; and
      this Guaranty, and any other documents and instruments required under this
      Guaranty, when issued and delivered under this Guaranty, will be valid and
      binding upon the undersigned in accordance with their terms.

   b.   The execution, delivery and performance of this Guaranty, and any
      other documents and instruments required under this Guaranty, are not in
      contravention of the unwaived terms of any indenture, agreement or
      undertaking to which the undersigned is party or by which it is bound.

   c.   No litigation or other proceeding before any court or administrative
      agency is pending, or to the knowledge of the officers of the undersigned
      is threatened against it, the outcome of which if determined adversely
      would have a material adverse effect on the properties, assets or
      financial condition of the undersigned ("Material Adverse Effect").

   d.   The audited balance sheet and operating statement of the undersigned
      dated March 31, 1999 and the unaudited balance sheet and operating
      statement of the undersigned dated December 31, 1999, previously furnished
      Bank, are complete and correct and fairly present the financial condition
      of the undersigned and the results of its operations; since said dates
      there has been no change in the financial condition of the undersigned
      that has resulted, or could result, in a Material Adverse Effect; to the
      knowledge of the undersigned's officers, the undersigned has no contingent
      obligations (including any liability for taxes) not disclosed by or
      reserved against in said balance sheets, and at the present time there are
      no material unrealized or anticipated losses from any present commitment.

   e.   The undersigned has reviewed its operations and those of its
      subsidiaries and major commercial counterparts with a view to assessing
      whether it or its subsidiaries' respective businesses will, in the
      receipt, transmission, processing, manipulation, storage, retrieval,
      retransmission or other utilization of data, be vulnerable to a year 2000
      issue.  Based on such review, the undersigned has no reason to believe
      that any Material Adverse Effect will occur with respect to its or its
      subsidiaries businesses or operations resulting from a year 2000 issue.

15.   COVENANTS:

e.   Promptly, not later than three (3) business days after becoming aware

reliance upon an exemption from the registration requirements pursuant to
Section 5 of the Securities Act of 1933, as amended (the "Act") and the rules

effect and there is no default under any Material Contract either by the
Acquired Company or, to the knowledge of Member, by any other party thereto, and
no event has occurred that with the lapse of time or the giving of notice or
both would constitute a default thereunder by the Acquired Company or to the
knowledge of the Acquired Company and Member, any other party of which could
result in termination of a Material Consent or which alone or in the aggregate,
would provide the basis for a claim against the Acquired Company.

4.9 Litigation. There is no claim, action, proceeding, or investigation pending
or, to their Knowledge, threatened against or affecting the Acquired Company or

Date.

does not, and the consummation by the member of the transactions contemplated
hereby will not, violate, conflict with or result in a breach of any provision
of, or constitute a default (or in an event which, with notice or lapse of time
