the covenants and other agreements of the parties hereto contained in this
Agreement shall survive the Closing and shall remain in full force and effect.

     8.2  Indemnification. Each of the parties hereto agrees to indemnify and
hold harmless (in such capacity, an "Indemnifying Party") each of the other
parties hereto and its Affiliates and their respective officers, directors,
employees, agents, successors and assigns (in such capacity, each an
"Indemnified Party") against and from all Losses incurred by such Indemnified
Parties arising out of (i) the breach of any representation or warranty of each
such Indemnifying Party contained herein, and (ii) the breach of any covenant or
agreement of each such Indemnifying Party contained herein.

     8.3  Indemnification Procedures. An Indemnified Party shall give the
Indemnifying Party prompt written notice of any claim, assertion, event or
proceeding by or in respect of a third Person of which such Indemnified Party
has knowledge concerning any Loss as to which such Indemnified Party may
request indemnification hereunder, provided, however, that the failure to
provide such notice shall not release the Indemnifying Party from any of its
obligations under this Article VIII, except to the extent the Indemnifying
Party is materially prejudiced by such failure. The Indemnifying Party shall
have the right to direct, at its sole option and expense, through counsel of its
own choosing, which counsel shall be reasonably satisfactory to the Indemnified
Party, the defense or settlement of any claim or proceeding the subject of
indemnification hereunder, except where the Indemnifying Party has failed to
timely undertake any defense, in which case the Indemnifying Party shall have no
right to participate in any settlement or assume the defense of such claim or
proceeding. If the Indemnifying Party elects to assume the defense of any such
claim or proceeding or negotiate, settle or otherwise deal with such claim or
proceeding, the Indemnified Party may participate in such defense, but in such
case the expenses of the Indemnified Party shall be paid by the Indemnified
Party; provided, however, that such Indemnified Party shall be entitled to
participate in any such defense with separate counsel at the expense of the
Indemnifying Party if (i) so requested by the Indemnifying Party to participate
or (ii) in the reasonable opinion of counsel to the Indemnified Party, a
conflict or potential conflict exists between the Indemnified Party and the
Indemnifying Party that would make such separate representation advisable. The
Indemnified Party shall provide the Indemnifying Party with access to its
records and personnel relating to any such claim, assertion, event or proceeding
during normal business hours or as otherwise may reasonably be required and
shall otherwise cooperate with the Indemnifying Party in the defense or
settlement thereof, and the Indemnifying Party shall reimburse the Indemnified
Party for all its reasonable out-of-pocket expenses in connection therewith. If
the Indemnifying Party elects to direct the defense of any such claim or
proceeding, the Indemnified Party shall not pay, or permit to be paid, any part
of any claim or demand arising from such asserted liability unless the
Indemnifying Party consents in writing to such payment or unless the
Indemnifying Party withdraws from the defense of such asserted liability or
unless a final judgment from which no appeal may be taken by or on behalf of the
Indemnifying Party is entered against the Indemnified Party for such liability.
No settlement in respect of any third Person claim may be effected by the
Indemnifying Party without the Indemnified Party's prior written consent unless
the settlement involves a full and unconditional release of the Indemnified
Party. If the Indemnifying Party shall fail to undertake any such defense, the
Indemnified Party shall have the right to undertake the defense or settlement
thereof, at the Indemnifying Party's expense. If the Indemnified Party assumes
the defense of any such claim or proceeding pursuant to this Section 8.3 and
proposes to settle such claim or proceeding prior to a final judgment thereon
or to forgo any appeal with respect thereto, then the Indemnified Party shall
give the Indemnifying Party prompt written notice thereof and the Indemnifying
Party shall have the right to participate in the settlement or assume or
reassume the defense of such claim or proceeding, except where the Indemnifying
Party has failed to undertake any defense, in which case the Indemnifying Party
shall have no right to participate in any settlement or assume the defense of
such claim or proceeding.

                                   ARTICLE IX

                             TERMINATION AND WAIVER

     9.1  Grounds for Termination.  This Agreement may be terminated at any time
prior to the Closing Date:

     (a)  By the written agreement of each of AMX and each of the BCI Group; or

     (b)  By either AMX or the BCI Group if the Closing shall not have occurred
on or prior to August 9, 2002, provided however, that the right to terminate
this Agreement under this Section 9.1(b) shall not be available to any party
whose failure (or whose Affiliate's failure), directly or indirectly, to fulfill
any obligation or covenant under this Agreement shall have been the cause of, or
shall have resulted in, the failure of the Closing to occur on or prior to
August 9, 2002.

     9.2  Effect of Termination. If this Agreement is terminated as permitted
under Section 9.1, such termination shall be without liability to any party to
this Agreement except (i) that the provisions of Sections 5.1, 6.1, 9.2, 10.1,
10.9, 10.10, 10.11, 10.12 and 10.14 shall survive the termination of this
Agreement and (ii) that nothing herein shall relieve any party from liability
for any willful breach of this Agreement.

                                       17

     9.3  Waiver. With respect to any party, the other parties may (a) extend
the time for the performance of any of the obligations or other acts of such
party, (b) waive any inaccuracies in the representations and warranties of such
parties contained herein or in any document delivered by such party pursuant
hereto or (c) waive compliance with any of the agreements or covenants of such
party contained herein. Unless and to the extent that a particular party is
expressly authorized to waive such inaccuracies or compliance under this
Agreement, any such extension or waiver shall be valid only if set forth in an
instrument in writing signed by the parties to be bound thereby. Any waiver of
any term or condition shall not be construed as a waiver by any party not a
signatory to such written instrument evidencing such waiver, a waiver of any
subsequent breach or a subsequent waiver of the same term or condition, or a
waiver of any other term or condition of this Agreement. The failure of any
party to assert any of its rights hereunder shall not constitute a waiver of
any of such rights.


                                   ARTICLE X

and expenses, regardless of whether or not the Closing shall have occurred.

communications hereunder shall be in writing and shall be given or made (and

for convenience of reference only and shall not affect in any way the meaning or
interpretation of this Agreement.

     10.4 Severability. If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any Law or public policy, all
other terms and provisions of this Agreement shall nevertheless remain in full
force and effect so long as the economic or legal substance of the transactions
contemplated hereby is not affected in any manner materially adverse to any
party. Upon such determination by a Governmental Authority that any term or
other provision is invalid, illegal or incapable of being enforced, the parties
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner in
order that the transactions contemplated hereby are consummated as originally
contemplated to the greatest extent possible.


                                       19

     10.5 Entire Agreement. This Agreement and the other Transaction Documents
and any other document entered into pursuant to the terms hereof or thereof
constitute the entire agreement of the parties hereto with respect to the
subject matter hereof and thereof.

     10.6 Assignment. This Agreement may not be assigned by operation of Law
or otherwise without the express written consent of each of the parties (which
consent may be granted or withheld in the sole discretion of each party).

     10.7 No   Third Person Beneficiaries. Except for the provisions of Article
VIII relating to Indemnified Parties, this Agreement shall be binding upon and
inure solely to the benefit of the parties and their permitted assigns and
nothing herein, express or implied, is intended to or shall confer upon any
other Person any legal or equitable right, benefit or remedy of any nature
whatsoever under or by reason of this Agreement.

     10.8 Amendment. This Agreement may not be amended or otherwise modified
except by an instrument in writing signed by, or on behalf of, each of the
parties.

     10.9 Governing Law. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of New York.

     10.10 Arbitration. (a) The parties agree that any controversy, claim or
dispute arising out of or relating to or in connection with this Agreement
including, without limitation, any dispute regarding its breach, termination,
enforceability or validity (each, a "Dispute") shall be finally settled by
binding arbitration in The City of New York, New York County, before a panel of
three arbitrators. The arbitration shall be administered by the International
Court of Arbitration of the International Chamber of Commerce (the "ICC") under
its Rules of Arbitration as in effect at the time of this Agreement, except as
they may be modified herein by agreement of the parties, and shall be conducted
in the English language. The BCI Group shall be deemed as a single party to the
arbitration. Each party shall nominate one arbitrator, obtain its nominee's
acceptance of such nomination, and deliver written notification of such
nomination and acceptance to the other party within thirty (30) days after
delivery of the request for arbitration. In the event a party fails to nominate
an arbitrator or deliver notification of such nomination to the other party
within this time period, upon request of any party, such arbitrator shall
instead be appointed by the ICC within thirty (30) days of receiving such
request. The two arbitrators nominated in accordance with the above provisions
shall nominate the third arbitrator, obtain the nominee's acceptance of such
nomination and notify the parties in writing of such nomination and acceptance
within thirty (30) days of their nomination. If the first two nominated
arbitrators fail to nominate a third arbitrator or notify the parties of that
nomination within this time period, then, upon request of either party, the
third arbitrator shall be appointed by the ICC within thirty (30) days of
receiving such request. Nonetheless, in no event shall any such arbitrator
nominated by the other arbitrators be a resident in, or a domicile of,
any country in which AMX or BCI is domiciled or has its principal place of
business. In the event a party fails to nominate an arbitrator or deliver
notification of such nomination to the other parties within this time period,
upon request of any party, such arbitrator shall instead be appointed by the ICC
within thirty (30) days of receiving such request. The three arbitrators


                                       20
<PAGE>

appointed in accordance with the above provisions shall mutually agree to
designate one of them to act as chair within thirty days of their appointment.
For the sake of clarity, it is expressly understood that the function of such
chair is administrative only and shall not signify that such chair has greater
or different powers as arbitrator from the other arbitrators. In the event that
the arbitrators nominated in accordance with the above provisions fail to agree
upon the selection of a chair within this time period, upon request of any
party, the chair shall instead be designated by the ICC within thirty days of
receiving such request. The award of the arbitrators shall be final and binding
upon the parties, and shall not be subject to any appeal or review. The parties
agree to submit to the nonexclusive personal jurisdiction of the federal and
state courts sitting in The City of New York, New York for the purpose of
enforcing this agreement to arbitrate.

     (b)  No provision of, nor the exercise of any rights under, this Section
10.10 shall limit the right of any party to request and obtain from a court of
competent jurisdiction in the City of New York (which shall have exclusive
jurisdiction for purposes of this Section 10.10(b)) before, during or after
the pendency of any arbitration, provisional or ancillary remedies and relief
including, but not limited to, injunctive or mandatory relief or the appointment
of a receiver. The institution and maintenance of an action or judicial
proceeding for, or pursuit of, provisional or ancillary remedies shall not
constitute a waiver of the right of any party, even if it is the plaintiff, to
submit the dispute to arbitration if such party would otherwise have such right.
Each of the parties hereby submits unconditionally to the exclusive jurisdiction
of the state and federal courts located in The City of New York, County of New
York for purposes of this provision, waives objection to the venue of any
proceeding in any such court or that any such court provides an inconvenient
forum and consents to the service of process upon it in connection with any
proceeding instituted under this Section 10.10(b) in the same manner as provided
for the giving of notice hereunder.

     (c)  Judgment upon the award rendered may be entered in any court having
jurisdiction. The parties hereby expressly consent to the nonexclusive
jurisdiction of the state and federal courts situated in The City of New York,
County of New York for this purpose and waive objection to the venue of any
proceeding in such court or that such court provides an inconvenient forum.

     (d)  Each of the parties participating in an arbitration pursuant to the
terms of this Agreement shall, subject to the award of the arbitrators, pay an
equal share of the arbitrators' fees. The arbitrators shall have the power to
award recovery of all costs (including reasonable attorneys' fees,
administrative fees, arbitrators' fees and court costs) to the prevailing party.

     (e)  Each of BCI, BCI Investments and AMX hereby irrevocably designates CT
Corporation, with offices situated at present at 111 Eighth Avenue, New York,
NY 10011 as its authorized agent, respectively, to accept and acknowledge on its
behalf service under this Agreement or any of the other Transaction Documents of
any process which may be served in any proceeding in the State of New York.

     10.11     Counterparts. This Agreement may be executed and delivered in one
or more counterparts, and by the different parties hereto in separate
counterparts, each of which when executed shall be deemed to be an original and
all of which taken together shall constitute one and the same agreement.

                                       21
<PAGE>


     10.12     Waiver of Jury Trial. Each of the parties hereto irrevocably and
unconditionally waives trial by jury in any legal action or proceeding relating
to this Agreement, the other Transaction Documents or the transactions
contemplated hereby and thereby and for any counterclaim therein.

     10.13     Set-off. All payments hereunder shall be made irrespective of and
free and clear of any right of counterclaim or set-off.

     10.14     Specific Performance. The parties agree that irreparable damage
would occur in the event any provision of this Agreement was not performed in
accordance with the terms hereof and that the parties shall be entitled to
specific performance of the terms hereof, in addition to any other remedy at
Law or in equity. Notwithstanding the foregoing, the transactions contemplated
by this Agreement are intended to be entered into concurrently and in
consideration of each other, and shall not be severable.

                [REMAINDER OF THIS PAGE INTENTIONALLY LEFT BLANK]


     IN WITNESS WHEREOF, each of the parties hereto has caused this
Agreement to be executed as of the date first written above by its respective
