                                VENDOR AGREEMENT

              Between:

              BEST BUY CO., INC.                DIRECTED ELECTRONICS, INC.
                                                --------------------------
              7075 Flying Cloud Drive    and    One Viper Way
                                                --------------------------
              Eden Prairie, MN 55344            Vista, CA 92085
                                                --------------------------

1.    LICENSE TO SELL PRODUCTS

Vendor grants Best Buy Co., Inc., and its affiliates and subsidiaries ("Best
Buy"), a non-exclusive license to distribute all products Vendor makes available
to Best Buy (the "Products"), to end users and commercial buyers in the United
States, and other territories as agreed from time to time, through its sales
channels including but not limited to its present and future stores, Internet
Website, (www.BestBuy.com), distribution centers and mail order distribution
centers.

2.    PRICING AND TAXES

-     PRICES: Vendor will sell the Products to Best Buy at the prices then in
      effect on its current price list, as may be changed from time to time, or
      as otherwise agreed between the parties. Prices exclude freight and
      insurance. Vendor guarantees competitive pricing.

-     TAXES: Vendor's prices do not include sales, use, excise, or similar
      taxes. The amount of any valid present or future sales, use, excise, or
      other similar tax which is attributable to Best Buy shall be paid by Best
      Buy; or in lieu thereof, Best Buy shall provide Vendor with a tax
      exemption certificate acceptable to the taxing authorities.

3.    PAYMENT

Vendor shall electronically submit an invoice to Best Buy on the same day
Product is shipped. Invoice credit terms will be set forth in the Vendor Program
Agreement as further described in Section 11. The designated credit term shall
commence on the date Best Buy verifies receipt of Product at the FOB point (e.g.
distribution center or store in the case of FOB destination shipping terms; or
by the Best Buy-assigned center in the case of FOB origin shipping terms). Best
Buy's policy is to cut and mail checks on the due date or first workday
thereafter. Thus, if the credit terms are net 60 days, Best Buy will send
payments 60 days after Best Buy verifies receipt of Product at the FOB
destination point. No additional charges of any type beyond the price of the
Products shall be added to an invoice without Best Buy's express written
consent. Vendor may not charge interest on any past due amounts as a result of
audits, claims or disputed deductions. All transactions must be valued and paid
in U.S. currency. Best Buy may offset against amounts payable to the Vendor all
present and future indebtedness of the Vendor to Best Buy arising from any
transaction.

Vendor will send invoices to Best Buy electronically as provided in Section 10
(Electronic Data Interchange; Web-Based Electronic Commerce). All invoices not
sent electronically should be sent to Best Buy Purchasing LLC, Attn: Accounts
Payable, P.O. Box 9331, Minneapolis, MN 55440-9331. Best Buy Purchasing LLC is a
controlled subsidiary of Best Buy Co., Inc. Best Buy Purchasing LLC will pay
Vendor invoices in accordance with this Section 3 and shall initially assume
title to all Products. Best Buy Purchasing LLC will resell and transfer title to
such Products to Best Buy Co., Inc.'s other affiliates and subsidiaries to
distribute the Products through the sales channels provided in Section 1. Best
Buy Co., Inc. guarantees the performance required of Best Buy Purchasing LLC
under this Agreement.

4.    SHIPPING

-     SELECT SHIPPING TERMS: One of the following ground shipment terms shall be
      agreed upon at the time this Agreement is executed by checking the
      applicable box. No other ground shipment terms other than the two options
      described below may be used.

[ ]   Best Buy's preferred method of shipping for domestic shipments is F.O.B.
      Origin, Freight Collect and Allowed. Best Buy shall be responsible for
      carrier selection routing instructions and pick-up appointments at
      Vendor's domestic origin facility. In addition, Best Buy is responsible
      for carrier freight payments except as otherwise specified in this
      Agreement, submitting freight claims for loss and damage, scheduling
      appointments at destination, and tracking and tracing freight in transit.
      Title and risk of loss passes to Best Buy Purchasing LLC upon delivery to
      Best Buy at Vendor's domestic origin shipping dock. Vendor agrees to have
      Products in "ship-ready" condition by the ship date as specified in the PO
      and further, provide 48-hour notice to Best Buy for truckload shipments
      and 24-hour notice to Best Buy for less-than-truckload shipments. Vendor
      will pay a freight allowance to Best Buy pursuant to the attached
      Collaborative Transportation Agreement, as amended from time to time by
      the parties.

[X]   Alternatively, Vendor shall ship Product to Best Buy FOB Destination,
      Freight Prepaid by Vendor to the location specified by Best Buy, including
      but not limited to its stores, distribution centers, and third-party
      fulfillment providers. Vendors are encouraged to utilize Best Buy's
      Preferred Carriers, as listed in the attached Routing and Shipping Guide.
      Because such Preferred Carriers are electronically linked with Best Buy's
      systems, Vendor's adherence to this request will improve tracking
      capability and on-time performance while producing shorter transit times
      and minimizing the need for Expedited Shipments, as defined below, to Best
      Buy's distribution centers and stores.

[***] - CERTAIN INFORMATION ON THIS PAGE HAS BEEN OMITTED AND FILED SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION. CONFIDENTIAL TREATMENT HAS BEEN
REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.

-     EXISTING VENDOR CONVERSION TO FOB ORIGIN, FREIGHT COLLECT AND ALLOWED
      TERMS: In the event Vendor currently ships Product to Best Buy FOB
      Destination, Freight Prepaid by Vendor, Vendor may be converted to the
      preferred FOB Origin, Freight Collect and Allowed terms as described
      above, via its Collaborative Transportation Management Program ("CTM").
      Under CTM, Best Buy will receive a negotiated freight allowance from the
      vendor in exchange for assuming the expenses associated with inbound
      carrier freight previously borne by Vendor. Freight allowance to be paid
      to Best Buy with respect to FOB Origin, Freight Collect and Allowed terms
      will be agreed between the parties in a writing and attached hereto as the
      Collaborative Transportation Agreement. For example, the negotiated
      freight allowance can reflect a flat percentage of invoice value, (ad
      valorem), or dollars and/or cents per pound, or dollars and/or cents per
      box or as actual freight expense incurred. Freight allowances and/or
      expenses will be reconciled after each Best Buy fiscal month.

-     EXPEDITED SHIPMENTS: Terms for expedited shipments will be FOB Origin,
      Freight Collect. Vendor will pay any additional freight expenses incurred
      in connection with an expedited shipment arising from a shipment delay
      caused by Vendor. The parties will determine responsibility for expedited
      shipment expenses in other situations on a case by case basis. In the
      event current shipping terms are FOB Origin, Freight Collect and Allowed,
      and the parties determine that the need for an expedited shipment was not
      the fault of Vendor, Vendor shall still be responsible for reimbursing
      Best Buy for the agreed Freight Allowance expense.

-     SHIPPING AND ROUTING GUIDE: Vendor shall follow the terms and conditions
      stated in Best Buy's Shipping and Routing Guide, which may be accessed at
      WWW.EXTENDINGTHEREACH.COM.

-     OTHER CHARGES: Any and all charges related to special requests of Vendor
      to carrier, including loading assistance, detention, or any other
      instructions, prior to title passage, are the responsibility of the
      Vendor.

-     DIRECT IMPORT AGREEMENT: Terms for directly Imported Products will be set
      forth in a Direct Import Agreement, which may be attached hereto.

-     BILL OF LADING: Vendor shall use Best Buy's standard Bill of Lading form,
      which may be accessed at WWW.EXTENDINGTHEREACH.COM.

5.    SHIPPING PERFORMANCE MANAGEMENT

-     RIGHT TIME: Vendor agrees to deliver Product on a timely basis to Best Buy
      at the FOB point in accordance with the prearranged delivery and/or
      pick-up dates the parties agree upon from time to time. For FOB Origin,
      Freight Collect terms, Product must be ready for delivery to Best Buy on
      the pick-up date committed to by Vendor. For FOB Destination, Freight
      Prepaid terms, Product must be delivered to Best Buy within two days of
      the delivery date committed to by Vendor. In the event Vendor is in breach
      of this "Right Time" shipping commitment, Vendor shall pay to Best Buy, or
      Best Buy may offset against Vendor invoice, in each instance of breach,
      [***] subject to the breach, as identified on the corresponding PO for
      each day early or late, as the case may be, [***]. Such amount shall be
      considered liquidated damages, as it is reasonable in light of Best Buy's
      anticipated loss for Vendor's non-conformance.

-     RIGHT QUANTITY: Vendor agrees to deliver the right quantity of Product to
      Best Buy in accordance with an accepted PO. However, Best Buy shall
      consider a PO-SKU quantity [***] a conforming delivery. If Vendor delivers
      a non-conforming quantity, Vendor shall pay to Best Buy, or Best Buy may
      offset against Vendor Invoice, an amount equal to the quantity
      non-conformance percentage multiplied by the total cost of the particular
      SKU subject to the non-conformity, as identified on the corresponding PO
      [***]. Such amount shall be considered liquidated damages, as it is
      reasonable in light of Best Buy's anticipated loss for Vendor's
      non-conformance.

-     PROGRAM IMPLEMENTATION: Vendor agrees to comply with Best Buy's
      implementation schedule for the Shipping Performance Management Program,
      as described above (Right Time; Right Quantity). Upon notice to Vendor of
      the commencement of the Program, Best Buy will provide information
      concerning Vendor's shipping performance to Vendor for [***]
      ("Implementation Period"). Vendor will not be subject to charges for
      shipping non-conformance during the Implementation Period. Following the
      Implementation Period, Vendor will be subject to the charges for shipping
      non-conformance as specified in this Section 5. Best Buy will identify and
      report incidents of Vendor's non-conforming shipments and make available
      information concerning each incident for 4 weeks prior to the date that
      any charge hereunder will be assessed so that Vendor may investigate and
      determine the validity of each incident of shipping non-conformance
      reported by Best Buy.

-     ACHIEVING SHIPPING PERFORMANCE STANDARDS: If Vendor maintains shipping
      conformance for Right Time and Right Quantity at a rate of [***] based
      upon the aggregate of all PO-SKU orders in such period Best Buy will
      suppress future charges for non-conformance, provided that Vendor
      continues to maintain weekly shipping performance at or above [***]
      conformance. In the event unforeseen circumstances prevent Vendor from
      maintaining this [***] threshold, in Best Buy's sole discretion, Vendor
      will be permitted to perform below [***] for [***] of a rolling 6-week
      period without reinstatement of charges for non-conformance. If Vendor
      first qualifies for suppression of charges but then later fails to
      maintain the [***] threshold performance standard or its limited exception
      for unforeseen circumstances, Vendor must reestablish shipping standards
      of [***] or greater for 13 consecutive weeks before non-conformance
      charges will again be suppressed.

6.    [***] Notice of Price Increases

      [***] Best Buy will receive [***] as per the current Vendor Program
      Agreement upon the effective date of a [***] to the Products with respect
      to Best Buy's [***] which shall include [***]. Best Buy will determine its
      [***] as of the effective date of [***] and will submit [***] to
      in-transit Product shall be reflected on the purchase orders prior to them
      being received into Best Buy distribution centers. Subject to Best Buy's
      audit rights herein, Best Buy will make commercially reasonable efforts to
      submit documentation to Vendor [***] after the effective date of the
      [***].

REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.

-     NOTICE OF PRICE INCREASES: Vendor will give Best Buy 90 days prior written
      notice of the effective date of any increases to the cost of Product to
      Best Buy. Price increases are based on the purchase order date, not the
      shipment date.

7.    RETURNS

Best Buy shall have the right to return at Vendor's expense, and for full credit
or refund of Best Buy's cost (which is Best Buy's last purchase price) any
Products (i) against which an allegation is made that the use of such Products

publicity, or any other tangible or intangible proprietary or intellectual
property right; (ii) are not manufactured, packaged, or labeled in accordance

Vendor to Best Buy, whether or not related to the performance of this Agreement)
with Best Buy, the amount owed will be deducted by Best Buy from the next
payment to Vendor. If there is no outstanding balance due Vendor, then Vendor
shall pay the debit balance to Best Buy in full, [***]. If the amount owed is
disputed, Vendor agrees to reconcile the account and remit payment to Best Buy
[***]. Payment shall be made in the form of check or wire; payment via a credit
memo is not acceptable. Best Buy may charge the Vendor interest [***], whichever
is greater, commencing as of the date of notification by Best Buy, for any debit
balances not reconciled and paid [***] from Best Buy.

9.    DISCONTINUED PRODUCT

A "Discontinued Product" means any Product that Vendor has stopped manufacturing
or any Product that undergoes a change in appearance or packaging. Vendor agrees
to provide Best Buy with at least 90 days advance written notice of the
occurrence of a Discontinued Product, or as soon as possible in the event that
the discontinuance is caused by actions taken by a component part supplier of
Vendor. Upon notice of such Discontinued Product, Best Buy may, without penalty
or liability, cancel any outstanding purchase orders pertaining to the
Discontinued Product. With respect to Best Buy's [***], Vendor and Best Buy

21.   AUDIT RIGHTS; CLAIMS AND CHARGE-BACKS

      written notice and at reasonable times during regular business hours,
      audit the other party to assure compliance with the terms and conditions
      of this Agreement. If the audit reveals that a party is not performing in
      material compliance with the terms of this Agreement, then, in addition to
      any other legal and equitable rights and remedies available, the party not
      in compliance shall reimburse the other for the reasonable costs of the
      audit.

      documentation. If no denial is received by Best Buy [***], Best Buy will
      assume the deductions were accepted by the Vendor, and Vendor hereby
      agrees not to contest such deductions. Rejected charge-backs must be
      returned using the Dispute Control Document, which may be accessed at
      www.extendingthereach.com.

22.   AVOIDANCE OF CONFLICT OF INTEREST; CODE OF CONDUCT STANDARDS

Vendor agrees to respect and abide by Best Buy's conflict of interest and code
of conduct policies, which may be amended from time to time and which will be
made available to Vendor upon request. Vendor agrees to contact Best Buy's Open
Line (1-800-520-1132) for information concerning Best Buy's policies and to
discuss any ethical or conduct concerns that they may have as a result of their
contact with Best Buy personnel. Vendor understands and acknowledges that Best
Buy's conflict of interest and code of conduct policies address Vendor-paid
travel, gifts and gratuities, offering and accepting bribes, family members and
close personal relationships involving employees of both parties, personal
investments in the other party, Vendor-sponsored charitable and other events,
Vendor product samples, Vendor promotional copies, direct personal purchases
from Vendors by Best Buy employees, and awards, incentives and other spiffs from
vendors. Vendor agrees to avoid conflict of interest situations with Best Buy,
to deal in arms length negotiations with Best Buy, and to contact Best Buy's
Open Line to address Vendor's concerns. Best Buy similarly agrees to abide by
Vendor's policies concerning this subject matter.

23.   FORCE MAJEURE

the control and without the fault or negligence of such party. Such causes may
include, but are not restricted to, acts of God or of a public enemy, acts of
the government in either its sovereign or contractual capacity, fires, floods,
epidemics, quarantine restrictions, strikes, freight embargoes, power failure,
or failure of the U.S. postal system, but in every case the failure to perform
must be beyond the control and without fault or negligence of the party failing
to perform. The Vendor also agrees to inform Best Buy of any Force Majeure event
within 48 hours of its occurrence. Failure to notify Best Buy of such an event
within 48 hours will result in forfeiture, by Vendor, to claim that such an
event had occurred.
