                            DISTRIBUTION AGREEMENT

THIS DISTRIBUTION AGREEMENT (this "Agreement") is entered into between MOTOROLA,
INC., a corporation duly organized and existing under the laws of the State of
Delaware, by and through its Personal Communications Sector, Latin America
Group, having a place of business at 600 North U.S. Highway 45, Libertyville,
Illinois 60048-1286, U.S.A. (hereinafter "Motorola"), and CellStar Ltd., a
company duly organized and existing under the laws of the State of Texas, having
its principal place of business at 2101 N.W. 82nd Avenue, Miami, Florida 33122
(hereinafter "Distributor"), effective as of April 15, 2000 ("Effective Date").

WHEREAS, Motorola manufactures communications equipment including, among others,
cellular telephones, two-way radios and messaging products and distributes them
directly to its customers and also through independent distributors;

WHEREAS, Motorola sells its communications equipment and accessories throughout
the world, including the country of Mexico and the regions of Central America,
South America and the Caribbean;

WHEREAS, Motorola wishes to continue selling its communications equipment and
accessories directly and also through independent distributors to customers in
Mexico, Central America, South America and the Caribbean, but Motorola also
wishes to expand its distribution system in Mexico, Central America, South
America and the Caribbean to include Distributor as a distributor; and

WHEREAS, Distributor wishes to become a distributor of the Motorola
communications equipment and accessories set forth in this Agreement in Mexico,
Central America, South America and the Caribbean.

NOW THEREFORE, the parties hereto hereby agree as follows:

1.   APPOINTMENT AS EXPORT DISTRIBUTOR

a.   Subject to the terms of this Agreement, Motorola hereby appoints
     Distributor, and Distributor hereby accepts the appointment, as an
     authorized non-exclusive distributor of models of the Motorola cellular
     telephone equipment, Motorola two-way radios, Motorola messaging products
     and Motorola accessories listed in Attachment 1 hereto (the "Products").
     Distributor is authorized to purchase Products directly from Motorola or
     from whom Motorola designates from time to time pursuant to purchase orders
     entered into in connection with this Agreement and resell such Products
     solely within and into the territory of Mexico, Central America, South
     America and the Caribbean that is described in Attachment 2 hereto
     (hereafter referred to as the "Territory"). Motorola may, from time to time
     and at its absolute discretion modify the list of Products or the
     Territory. From time to time, Motorola will provide price lists to
     Distributor for the Products which Distributor is authorized to distribute
     in the Territory.

b.   Distributor acknowledges and agrees that Motorola reserves the right to
     limit distribution of certain Motorola cellular telephone product lines to
     distributors who satisfy Motorola's qualification criteria for distribution
     of such product lines. Distributor hereby consents to the application of
     such criteria to its distribution in the Territory of Products purchased in
     connection with this Agreement.

c.   Distributor acknowledges and agrees that Motorola reserves the right to
     appoint other distributors within or for the Territory and that Motorola
     may, at its sole and unrestricted discretion, chose to use other agents,
     dealers, distributors, representatives and independent contractors, as well
     as its regularly employed sales force and that of its subsidiaries or
     affiliated companies, to promote the sale of Products within the Territory.

d.   Distributor acknowledges and agrees that Motorola reserves the right to
     restrict the distribution of specific models of Products to specific areas
     and/or customers within the Territory and Distributor agrees to limit its
     distribution of such models accordingly.

                                                   Master Distribution Agreement
                                                                  CellStar, Ltd.
                                                                  April 15, 2000
                                                                          Page 2
--------------------------------------------------------------------------------

e.   In the event that a direct sale between Motorola, as the seller, and a
     third party located within the Territory as the buyer, takes place as a
     direct and immediate result of Distributor's efforts to promote such sale,
     Motorola may elect to compensate Distributor for its efforts by paying a
     commission calculated in accordance with and subject to terms and
     conditions of a separate written agreement between the parties.

2.   TERM OF THIS AGREEMENT

     The term of this Agreement shall commence on the Effective Date and shall
     continue for one year, unless terminated as permitted herein. At the end of
     the one-year term, this Agreement shall automatically renew for successive
     periods of one-year unless within thirty (30) days prior to any such
     scheduled renewal date one party notifies the other party that it will not
     renew this Agreement. The number of renewals notwithstanding, this
     Agreement is and shall always be interpreted as a fixed term agreement and
     not as an indefinite term agreement.

3.   PARTY RELATIONSHIP

     It is agreed that Distributor's relationship to Motorola is that of an
     independent contractor and no other relationship is intended to be created
     between the parties hereto. Nothing in this Agreement shall be construed so
     as to make Distributor or its employees or agents an employee of Motorola
     or an agent with the power to bind Motorola contractually. Distributor
     shall have no authority to bind, obligate or incur any liability on behalf
     of Motorola. This Agreement does not create any agency, joint venture or
     partnership between Distributor and Motorola.

4.   DISTRIBUTOR RESPONSIBILITIES

     In distributing Products Distributor shall perform the following services:

a.   Export the Products from the U.S. to the Territory.

b.   Sell, advertise and promote the sale and use of Products throughout the
     Territory.

c.   Maintain a sales organization adequate to effectively promote and market
     the Products in the Territory.

d.   Purchase the Products from Motorola in the manner described in Section 5.

e.   Furnish to Motorola information relating to orders, sales, service and
     inventory of Products and Product sales budgets and forecasts in such
     manner as Motorola may require.

f.   Furnish Motorola, upon Motorola's request, detailed market analyses and
     reports with respect to the Territory.

g.   Perform the value added services in the manner described in Section 9.

5.   PURCHASE OF PRODUCTS

a.   Under the terms and conditions of this Agreement, Distributor agrees to
     purchase at its own risk and for its own account, Products to be resold in
     the Territory, solely from Motorola's Personal Communications Sector, Latin
     America Group or any other supplier approved by the Latin America

                                                   Master Distribution Agreement
                                                                  CellStar, Ltd.
                                                                  April 15, 2000
                                                                          Page 3
--------------------------------------------------------------------------------

     Group. Distributor shall submit to Motorola for its acceptance purchase
     orders listing the model, quantity, shipment date, and price of the
     Products requested. Distributor may also include in the purchase order any
     of the programming specifications Motorola has for Latin America as
     Distributor may require. All other terms and conditions on Distributor's
     purchase order form are hereby rendered null, void, and of no effect, by
     the terms and conditions of this Agreement.

b.   Prices stated on Distributor's purchase orders shall conform to Motorola's
     then current price list, copies of which will be made available to
     Distributor.

c.   Motorola reserves the right in its sole discretion to accept or reject any
     order for Products received from Distributor without any further liability,
     including without limitation for the failure of Distributor to satisfy
     Motorola's distribution qualification requirements for distribution of the
     requested Product. No purchase order is binding on Motorola until accepted.
     A purchase order is accepted by Motorola when Product is shipped or when
     acceptance is acknowledged in writing by a duly authorized officer or
     employee of Motorola, whichever occurs first.

d.   Distributor shall submit firm processable purchase orders no less than
     thirty (30) days prior to the requested shipment date, unless otherwise
     agreed to by Motorola.

e.   Distributor may cancel orders placed in accordance with the terms and
     conditions of this Agreement upon payment of cancellation charges which
     shall include all costs incurred or committed for unless such costs are
     otherwise recoverable through the sale of the Product on a timely basis.
     Motorola agrees to divert completed material and work-in-process from
     canceled orders to other requirements wherever possible in order to
     minimize cancellation charges.

f.   Distributor shall provide Motorola on a monthly basis, not less than thirty
     (30) days prior to the start of the next month, a continuous usage forecast
     for the next six (6) calendar months (the "Forecast") to assist Motorola in
     maintaining an orderly production flow for the purpose of Distributors
     delivery requirements.  Distributor shall indicate the Product model number
     and project purchase volume by units for each month of the Forecast.
     Distributor's failure to provide such information may be considered cause
     for Motorola's excusable delivery delay.

6.   PAYMENT AND DELIVERY

a.   Unless otherwise approved in writing by Motorola, Distributor must pay for
     Products at any of the Motorola's bank accounts listed below, in U.S.
     currency by wire transfer within the thirty (30) days following the date of
     the invoice, which date shall be the same date of the shipment of the
     Products, from Motorola's manufacturing facility, corresponding to said
     invoice. The following is Motorola's banks information:

     Bank One
     One First National Plaza
     Chicago, IL 60670
     Motorola Account Number 57-51-551
     ABA 071000013

<PAGE>

                                                   Master Distribution Agreement
                                                                  CellStar, Ltd.
                                                                  April 15, 2000
                                                                          Page 4
--------------------------------------------------------------------------------

b.   All deliveries are FCA the applicable Motorola manufacturing facility in
     the U.S.A., as defined in INCOTERMS 2000. Title to the Products sold shall
     pass to Distributor at the FCA point.

c.   If Distributor should fail to pay any invoice for Products in accordance
     with its terms, or in the event that Motorola, in its sole discretion deems
     Distributor's financial condition inadequate or unsatisfactory, then in
     addition to its other rights herein, Motorola may repossess the unpaid
     Products, cancel any previously accepted purchase order for Products, or
     delay any further shipment of Products to Distributor, without incurring
     any liability for loss or damage of any kind occasioned by reason of any
     such cancellation or delay. Furthermore, such failure to pay may be deemed,
     at Motorola's option, a justified cause for termination of this Agreement.

7.   PRICE PROTECTION

a.   During the term of this Agreement, if Motorola reduces the price of a
     particular model of Product, then Motorola will credit Distributor's
     account an amount equal to the difference between the old and the new net
     purchase price (in each case, invoice price less rebate and any promotional
     amounts) multiplied by the number of such Product units purchased from
     Motorola which were shipped within thirty five (35) days prior to the new
     price effective date ("Eligible Products"). Eligible Products shall not
     include any close out products. Such amount will be credited within fifteen
     (15) days after the new price effective date, to apply to future orders of
     Products.

8.   NO TRANSSHIPMENT

a.   Distributor agrees to limit its distribution of the Products purchased
     hereunder to direct sale by Distributor to customers located in the
     Territory. Distributor may sell Products only from its address written
     above or such other location as is expressly authorized by Motorola.

b.   Distributor may not transship, sell or otherwise transfer Products
     purchased hereunder outside the Territory. Distributor shall incorporate
     this limitation into all of its agreements for the resale of Products
     purchased hereunder and Distributor shall enforce this restriction.

c.   Sales within the Territory without transshipment is a material condition to
     Distributor's rights under this Agreement, and it is agreed that any direct
     or indirect transfer, transshipment and/or sale of Products outside the
     Territory by Distributor or others purchasing through Distributor shall be
     a material breach of this Agreement and will result in substantial damage
     to Motorola which will be difficult to quantify. Accordingly, the parties
     agree that for every Motorola cellular telephone with electronic serial
     number traceable to purchases by Distributor from Motorola hereunder that
     is resold outside the Territory, Distributor will be subject, at Motorola's
     discretion, to pay Motorola as liquidated damages two times the FCA price
     per unit.

d.   In the event of any transshipment Motorola may immediately terminate this
     Agreement for cause; or Motorola may reject some or all purchase orders
     from Distributor for any model or models of Product and/or Motorola may

     best of Distributor's knowledge, the Equipment, Software and Documents
     received from Motorola have been returned, and that all Software placed in
     any storage apparatus under Distributor's control has been rendered
     unusable.

f.   Upon termination of this Agreement Motorola shall have the option, but not
     the obligation, to repurchase all or any part of the remaining inventory of
     the Products remaining in Distributor's possession at the net price paid to
     Motorola for such inventory, less Motorola's cost or repairing, renewing or
     reconditioning such repurchased Products. Said option shall be exercisable
     upon written notice to Distributor within thirty (30) days following notice
     of termination of this Agreement. Upon exercise of said option to
     repurchase, Motorola and Distributor shall at Motorola's option take an
     inventory of all Products remaining in Distributor's possession. Motorola
     shall pay Distributor for the inventory of repurchased Products within
     sixty (60) days after receipt thereof by Motorola. Motorola shall have the
     right to offset against any Moines payable hereunder any Moines that are
     due and owing from Distributor to Motorola as of the date any such payment
     is due.

22.  GOVERNMENT SALES

     In the event that Distributor elects to sell Motorola products or services
     to the U.S. Government or any foreign, state, county, municipal or other
     governmental entity, or to a prime contractor selling to any such
     governmental entity within the Territory, Distributor remains solely and
     exclusively responsible for compliance with all statutes and regulations
     governing such sales. Motorola makes no representations, certifications or
     warranties whatsoever with respect to the ability of its goods, services or
     prices to satisfy any such statutes or regulations. Failure of Distributor
     to conduct any sales to such a governmental entity or to such a prime
     contractor in strict accordance with applicable laws and regulations shall
     constitute a material breach of this Agreement.

23.  DISPUTE RESOLUTION

     The parties agree that any claims or disputes will be submitted to non-
     binding mediation prior to initiation of any formal legal process. Costs of
     mediation will be shared equally. Disputes concerning the relationship
     between Motorola and Distributor shall be resolved in accordance with the
     laws of the State of Illinois, U.S.A. and any court actions shall be filed
     in a state or federal court of competent jurisdiction in the State of
     Illinois. Distributor hereby consents to exclusive jurisdiction by such
     courts. Distributor waives personal service of any process upon it and
     consents that all service of process shall be made by registered mail to it
     at the address set forth in the introductory paragraph of this Agreement.

24.  EXPORT CONTROL

a.   Distributor shall be the exporter of record and shall be responsible for
     obtaining all export licenses that may be required to export the Products
     from the U.S. to the Territory.

b.   Distributor agrees to comply with all applicable export laws, regulations
     and orders. Specifically, but without limitation, Distributor agrees that
     it will not resell, reexport or ship, directly or indirectly, any Product
     or technical data in any form without obtaining appropriate export or
     reexport or ship, directly or indirectly, any Product or technical data in
     any form without obtaining appropriate export or reexport licenses from the
     United States Government. Distributor acknowledges that the applicable
     export laws, regulations and orders may differ from item to item and/or
     from time to time.

25.  COMPLIANCE WITH LAW

     Distributor shall at all times conduct its efforts hereunder in strict
     accordance with all applicable laws and regulations and with the highest
     commercial standards. Distributor shall effect or secure and maintain at
     its own cost all necessary governmental permits, licenses, approvals and
     registrations required in connection with the execution or performance of
     this Agreement and the importation and resale of the Products in the
     Territory. Specifically, it shall be Distributors responsibility to confirm
     that the Products comply with the applicable standards in the Territory for
     the operation of cellular telephones and to obtain any governmental
     approvals or licenses needed for such operation. Distributor shall
     indemnify and hold Motorola harmless for any losses, damages or other
     liabilities resulting from Distributor 's failure to comply with the
     provisions of this Section.

26.  ETHICAL STANDARDS

     Motorola has historically depended on product quality and superiority,
     combined with outstanding support capability, to sell its Products in all
     parts of the world. Motorola believes it can continue to grow and to
     prosper without succumbing to legally questionable or unethical demands.
     Motorola will not do business with any dealer, distributor, agent, customer
     or any other person where Motorola knows or suspects the existence of
     questionable practices. Distributor agrees with the Motorola policy stated
     in this Section and agrees that failure of Distributor or any other person
     under its responsibility to comply in all respects with said policy shall
     constitute just cause for immediate termination of this Agreement by
     Motorola without any liability.

27.  CONFIDENTIALITY

a.   All terms of this Agreement, including any Product pricing information
     delivered hereunder, are confidential.

b.   Distributor shall treat as confidential all Motorola business or technical
     information that Distributor learns in its conversations with Motorola
     concerning Distributor acting as a distributor of the Products or in
     performance of its responsibilities hereunder. Such information is
     collectively referred to as "Motorola Confidential Proprietary
     Information". The foregoing obligation of confidentiality shall commence on
     the first date that Motorola discloses to Distributor Motorola Confidential
     Proprietary Information and continue for a period of three years following
     termination of this Agreement. Distributor shall protect the
     confidentiality of Motorola Confidential Proprietary Information disclosed
     to it, using the same degree of care as Distributor uses to protect its own
     confidential proprietary

     information of like kind (but in no event less than a reasonable standard
     of care). Distributor shall not use any Motorola Confidential/Proprietary
     Information, except as necessary for performance of its responsibilities
     hereunder.

c.   Distributor shall limit disclosure of Motorola Confidential Proprietary
     Information to only those of its employees, agents and representatives with
     a need to know for the purposes authorized herein, and who have signed
     written agreements containing provisions of confidentiality similar to
     those contained in this Section.

d.   Distributor shall not disclose any Motorola Confidential Proprietary
     Information to any third party without Motorola's prior written consent.

e.   Excluded from the obligations of confidentiality in this Section is
     information known or that becomes known to the general public without
     breach by Distributor of this Agreement.

f.   Upon termination of this Agreement, Distributor shall return to Motorola
     all copies of Motorola Confidential Proprietary Information in its
     possession or certify to Motorola in writing that all such copies have been
     destroyed. Notwithstanding the foregoing, Distributor may retain one copy
     of the Motorola Confidential Proprietary Information but only for purposes
     of ensuring that Distributor continues to maintain the confidentiality of
     the information contained therein for the survival period stated above in
     Section 27(a).

g.   In the event that prior to or after execution of this Agreement Distributor
     and Motorola have entered into or do enter into a separate non-disclosure
     agreement covering the same Motorola Confidential Proprietary Information,
     then that separate non-disclosure agreement shall continue to apply for the
     period stated therein and Section 27 of this Agreement shall also apply for
     the period herein.

h.   Distributor further agrees to maintain the confidentiality of the personal
     identification numbers (PINs) associated with the ACE cards required for
     access to Motorola Computers by allowing only a single employee of
     Distributor to possess the PIN number for an ACE card.

28.  GENERAL

a.   No alterations or modifications of this Agreement shall be binding upon
     either Distributor or Motorola unless made in writing and signed by an
     authorized representative of each party.

b.   If any term or condition of this Agreement shall to any extent be held by a
     court or other tribunal to be invalid, void or unenforceable, then that
     term or condition shall be inoperative and void insofar as it is in
     conflict with law, but the remaining rights and obligations of the parties
     shall be construed and enforced as if this Agreement did not contain the
     particular term or condition held to be invalid, void or unenforceable.

c.   No assignment of this Agreement or of any right granted herewith shall be
     made by Distributor without the prior written consent of Motorola.

d.   This Agreement shall be governed by the laws of the State of Illinois,
     U.S.A.

e.   This Agreement and its attachments set forth the entire understanding
     between the parties hereto and supersedes all prior agreements, including
     the Memorandum of Understanding dated March 23, 2000, arrangements and
     communications, whether oral or written, with respect to the subject matter
     hereof. No other agreements, representations, warranties or other matters,
     whether oral or written, shall be deemed to bind the parties hereto with
