directly or indirectly controls, is controlled by, or is under common control
with, the Purchaser. The terms "controlled by" and "under common control with"

         (g) "Term" shall have the meaning set forth in Section 3.

2. PURCHASE REQUIREMENTS.

         (a) Subject to Section 2(b), Purchaser agrees to purchase (and cause
the Purchaser Affiliated Entities to purchase), upon the terms and conditions
set forth herein, all of the requirements of Purchaser and the Purchaser
Affiliated Entities for CCTV Products. Accordingly, and subject to Section 2(b),
in connection with Purchaser's or any Purchaser Affiliated Entities' sales or
installations of security systems that incorporate or utilize CCTV Products,
whether digital or analog, regardless of the identity of the customer and
regardless of whether Purchaser or any Purchaser Affiliated Entity is acting as
a systems integrator or designer, manufacturer, seller or distributor of access
control products and systems, Purchaser agrees that neither Purchaser nor any of
the Purchaser Affiliated Entities shall, during the Term of this Agreement,
purchase from any source other than Supplier, or otherwise acquire or
manufacture, any CCTV Products, except as otherwise permitted by this Agreement.



                                       2
<PAGE>

         (b) Purchaser shall deliver to Supplier on or before the first day of
each calendar quarter during the Term a non-binding forecast of the quantity and
description of CCTV Products anticipated to be required by Purchaser during such
calendar quarter.

             (i) Orders in the Ordinary Course. Purchaser's orders in the
ordinary course of business for CCTV Products shall be filled (generally from
inventory) consistent with Supplier's customary business practices. If Purchaser
delivers to Supplier a written purchase order (including via electronic
transmission) in the ordinary course of business for CCTV Products, such order
will be deemed to be rejected by Supplier if Supplier fails to respond to
Purchaser by either filling the order or confirming in writing within five (5)
business days after receipt of such order a reasonable delivery time schedule.

             (ii) Orders Outside the Ordinary Course. Supplier and Purchaser
shall cooperate with each other and use commercially reasonable efforts to
coordinate delivery time schedules with respect to orders outside the ordinary
course of business (generally involving large projects or contracts).

this Agreement shall be void and the provisions of this Agreement shall control.

         Supplier shall use all commercially reasonable efforts to sell to
Purchaser its requirements for CCTV Products as contemplated in Section 2(a)
herein. In the event Supplier is unable to supply a CCTV Product in sufficient
quantity and within a commercially reasonable time to fulfill Purchaser's
requirements for such CCTV Product or a customer of Purchaser or a Purchaser
Affiliated Entity requests a CCTV Product not manufactured by Supplier,
Purchaser or such Purchaser Affiliated Entity may procure such CCTV Product from
an alternative source until such time as Supplier is able to meet Purchaser's or
the Purchaser Affiliated Entity's requirements for such CCTV Product within a
commercially reasonable time; provided, however, that Purchaser and each
Purchaser Affiliated Entity shall be permitted to procure CCTV Products from an
alternative source only after (i) using commercially reasonable efforts to
encourage its customer to purchase CCTV Products either manufactured by Supplier
or which Supplier is able to source within a commercially reasonable time from
third parties (including CCTV Products available through Supplier which are the
functional equivalent of the CCTV Product requested by Purchaser's or the
Purchaser Affiliated Entity's customer), and (ii) providing Supplier with
reasonable written notice (including email) that a customer of Purchaser or such
Purchaser Affiliated Entity requires CCTV Products which Supplier is unable to
manufacture or source from third parties. Such procurement from alternative
sources shall be Purchaser's sole remedy in the event Supplier is unable to
supply CCTV Products to Purchaser.

         (c) Notwithstanding anything to the contrary in this Agreement, the
terms of this Agreement shall not apply with respect to the Sellers' purchase of
products in connection with the Excluded Businesses.

with respect to CCTV Products manufactured or acquired by Ultrak or any
Purchaser Affiliated Entity prior to the date hereof.

         (b) Purchaser shall be entitled to offer, as an exclusive limited
warranty to Purchaser's customers, the Limited Warranty. Purchaser covenants and
agrees not to make or offer any other warranty with respect to CCTV Products
unless Purchaser retains full responsibility for such additional warranty.

SUPPLIER'S CUSTOMARY PRODUCT WARRANTY POLICIES IN EFFECT AS OF THE DAY A CCTV

be defective by the Purchaser, Purchaser shall follow the procedures shown in

         Supplier and Purchaser shall discuss mutually and make the best effort
to resolve any dispute under this Agreement. In the event such negotiations are
not successful within thirty (30) calendar days, all disputes, controversies or
differences which may arise between the parties hereto, out of or in relation to

settled by arbitration. Within ten (10) calendar days after receipt of written

issue within thirty (30) calendar days after the completion of the hearings. The
determination of the arbitrators as to the resolution of any dispute shall be
binding and conclusive upon all parties hereto. All rulings of the arbitrators
shall be in writing, with the reasons for the ruling given, and shall be
delivered to the parties hereto. Each party shall pay the fees of its respective
designated arbitrator and its own costs and expenses of the arbitration. The
fees of the third arbitrator shall be paid fifty percent (50%) by each of the
parties. Any arbitration pursuant to this Section 15 shall be conducted in
Dallas, Texas. Any arbitration award may be entered in and enforced by any court
having jurisdiction thereof and the parties hereby consent and commit themselves
to the jurisdiction of the courts of any competent jurisdiction for purposes of
the enforcement of any arbitration award. Any party may seek from any court
interim or provisional relief that is necessary to protect the rights or
property of that party, pending the appointment of the arbitrator or pending the
arbitrator's determination of the merits of the controversy. None of the parties
shall be required to use the foregoing procedures to enforce the provisions of
Section 15 of this Agreement.

16. WAIVER.

         No delay or failure of any party in exercising any right, power or
remedy hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right, power or remedy preclude other or further
exercise thereof or the exercise of any other right, power or remedy.

17. SEVERABILITY.

         If under any applicable and binding law or rule of any applicable
jurisdiction, any provision of this Agreement is held to be invalid or
unenforceable, the invalid or enforceable provision, or any portion thereof,
shall be modified to the extent required to be valid and enforceable and the
remaining provisions of this Agreement will continue to be given full force and
effect.

18. GOVERNING LAW.

         This Agreement will be construed, performed and enforced in accordance

parties expressly agree that the U.N. Convention on International Sales of Goods
shall not apply.

19. CHOICE OF VENUE.

parties hereto. Each of the parties hereby irrevocably and unconditionally
submits, for itself and its property, to the exclusive jurisdiction of any
Delaware State court or Federal court of the United States of America sitting in

of Supplier's CCTV Products business; and provided further, however, that in the
event Purchaser shall sell or transfer the assets or business of Purchaser which
