Closing Date, each Voxx Assignor shall and shall cause the Lockbox Bank to enter
into all such documentation acceptable to Laurus pursuant to which, among other
things, the Lockbox Bank agrees to, following notification by Laurus (which
notification Laurus shall only give following the occurrence and during the

any Voxx Account (as defined below) of any Voxx Assignor or any other amount

payments be made to the Lockbox or such other address as Laurus may direct in

original form with all necessary endorsements. Until so remitted, such Assignor
or such other subsidiary of the Company shall hold all such payments in trust

of its other funds or property. For the purpose of this Master Security
Agreement, (x) "Voxx Accounts" shall mean all "accounts", as such term is
defined in the Uniform Commercial Code as in effect in the State of New York on
the date hereof, now owned or hereafter acquired by any Voxx Assignor (or any
other Assignor for the benefit of any Voxx Assignor) and (y) "Voxx Account
Debtor" shall mean any person or entity who is or may be obligated with respect
to, or on account of, a Voxx Account. Laurus and each Assignor agree that so

its corporate purposes as directed by the Voxx Assignors;

<PAGE>

contrary, each Voxx Assignor is permitted to continue factoring its account
receivables owed by Discover Financial Services, Inc. and CompuCredit

Assignor by any factoring company (each, a "Factor") conducting the Permitted
Factoring Arrangements, (x) a Factor shall be deemed a Voxx Account Debtor and
(y) all receipts and other amounts payable by a Factor to any Voxx Assignor
shall be deposited and handled in accordance with the provisions of Section 3(k)
hereof;

                  25.13    For so long as their shall be any Obligations due and
owing to Laurus in respect of this Master Security Agreement and/or any
Document, all business of the type and nature currently conducted by the Company
and its subsidiaries (the "Voxx Business") shall continue to be conducted by the
Company and its subsidiaries (either now existing or hereon after formed as a
wholly-owned subsidiary) (the "Business Entities") hereon in and after; and

                  (n)      From and after the date hereof, the Company and Voxx
         Corporation will, as soon as practicable, use their collective best
         efforts to cause all assets, accounts, obligations, functions and other
         elements associated with the Voxx Business which are not, as of the
         date hereof, conducted or owned by Voxx Corporation or any of its
         Subsidiaries, to be consolidated within the Voxx Business Entities for
         the purpose of centralizing the Voxx Business within the Voxx Business
         Entities and thereby establishing the Voxx Business as a free-standing,
         independent operating enterprise capable of consummating an initial
         public offering with minimal operational and financial reliance upon
         the Company and its Subsidiaries that do not consist of the Voxx

         seizure or attachment thereof or thereon except to the extent:

                  (a)      such loss is covered by insurance proceeds which are
         used to replace the item or repay Laurus; or

                  (b)      said levy, seizure or attachment does not secure
         indebtedness in excess of $100,000 and such levy, seizure or attachment
         has not been removed or otherwise released within thirty (30) days of
         the creation or the assertion thereof;

                  26.2     any Assignor shall become insolvent, cease
operations, dissolve, terminate our business existence, make an assignment for
the benefit of creditors, suffer the appointment of a receiver, trustee,
liquidator or custodian of all or any part of Assignors' property;

                  26.3     any proceedings under any bankruptcy or insolvency
law shall be commenced by or against any Assignor and if commenced against any

defined in any Document.

<PAGE>

         27.      Upon the occurrence of any Event of Default and at any time
thereafter, Laurus may declare all Obligations immediately due and payable and
Laurus shall have the remedies of a secured party provided in the Uniform
Commercial Code as in effect in the State of New York, this Agreement and other
applicable law. Upon the occurrence of any Event of Default and at any time
thereafter, Laurus will have the right to take possession of the Collateral and
to maintain such possession on our premises or to remove the Collateral or any
part thereof to such other premises as Laurus may desire. Upon Laurus' request,
each of the Assignors shall assemble or cause the Collateral to be assembled and
make it available to Laurus at a place designated by Laurus. If any notification
of intended disposition of any Collateral is required by law, such notification,
if mailed, shall be deemed properly and reasonably given if mailed at least ten
(10) days before such disposition, postage prepaid, addressed to any Assignor
either at such Assignor's address shown herein or at any address appearing on
Laurus' records for such Assignor. Any proceeds of any disposition of any of the
Collateral shall be applied by Laurus to the payment of all expenses in
connection with the sale of the Collateral, including reasonable attorneys' fees
and other legal expenses and disbursements and the reasonable expense of
retaking, holding, preparing for sale, selling, and the like, and any balance of
such proceeds may be applied by Laurus toward the payment of the Obligations in
such order of application as Laurus may elect, and each Assignor shall be liable
for any deficiency. For the avoidance of doubt, following the occurrence and
during the continuance of an Event of Default, Laurus shall have the immediate
right to withdraw any and all monies contained in the Lockbox Deposit Accounts
and any other deposit accounts under the control of Laurus and apply same to the
repayment of the Obligations in accordance with the terms of the Intercreditor
Agreement. Notwithstanding anything to the contrary contained in this Master
Security Agreement, the Purchase Agreement or any Related Agreement, in the
event that Laurus exercises the remedies provided for in this Section 5, Laurus
agrees to apply the amounts (if any) set forth in the Lockbox Deposit Accounts
prior to exercising its other remedies provided for in this Section 5.

         28.      If any Assignor defaults in the performance or fulfillment of
any of the terms, conditions, promises, covenants, provisions or warranties on
such Assignor's part to be performed or fulfilled under or pursuant to this
Master Security Agreement (following any applicable grace period), Laurus may,
at its option without waiving its right to enforce this Master Security
Agreement according to its terms, immediately or at any time thereafter and
without notice to any Assignor, perform or fulfill the same or cause the
performance or fulfillment of the same for each Assignor's joint and several
account and at each Assignor's joint and several cost and expense, and the cost
and expense thereof (including reasonable attorneys' fees) shall be added to the
Obligations and shall be payable on demand with interest thereon at the highest
rate permitted by law.

<PAGE>

         29.      Each Assignor appoints Laurus, any of Laurus' officers,
employees or any other person or entity whom Laurus may designate as our
attorney, with power to execute such documents in each of our behalf and to
supply any omitted information and correct patent errors in any documents
executed by any Assignor or on any Assignor's behalf; to file financing
statements against us covering the Collateral (and, in connection with the
filing of any such financing statements, describe the Collateral as "all assets
and all personal property, whether now owned and/or hereafter acquired" (or any
substantially similar variation thereof)); following any Event of Default and
any applicable period of grace, to sign our name on public records; and to do
all other things Laurus deem necessary to carry out this Master Security
Agreement. Each Assignor hereby ratifies and approves all acts of the attorney
and neither Laurus nor the attorney will be liable for any acts of commission or
omission, nor for any error of judgment or mistake of fact or law other than
gross negligence or willful misconduct (as determined by a court of competent
jurisdiction in a final and non-appealable decision). This power being coupled
with an interest, is irrevocable so long as any Obligations remains unpaid.

         30.      No delay or failure on Laurus' part in exercising any right,
privilege or option hereunder shall operate as a waiver of such or of any other
right, privilege, remedy or option, and no waiver whatever shall be valid unless
in writing, signed by Laurus and then only to the extent therein set forth, and
no waiver by Laurus of any default shall operate as a waiver of any other
default or of the same default on a future occasion. Laurus' books and records
containing entries with respect to the Obligations shall be admissible in
evidence in any action or proceeding, shall be binding upon each Assignor for
the purpose of establishing the items therein set forth and shall constitute
prima facie proof thereof (in the absence of manifest error or fraud). Laurus
shall have the right to enforce any one or more of the remedies available to
Laurus, successively, alternately or concurrently. Each Assignor agrees to join
with Laurus in executing financing statements or other instruments to the extent
required by the Uniform Commercial Code in form satisfactory to Laurus and in
executing such other documents or instruments as may be required or deemed
necessary by Laurus for purposes of affecting or continuing Laurus' security
interest in the Collateral.

<PAGE>

         31.      This Master Security Agreement shall be governed by and
construed in accordance with the laws of the State of New York and cannot be
terminated orally. All of the rights, remedies, options, privileges and
elections given to Laurus hereunder shall inure to the benefit of Laurus'
successors and assigns. The term "Laurus" as herein used shall include Laurus,
individually and in its capacity as collateral agent pursuant to the
Intercreditor Agreement, any parent of Laurus', any of Laurus' subsidiaries and
any co-subsidiaries of Laurus' parent, whether now existing or hereafter created
or acquired, and all of the terms, conditions, promises, covenants, provisions
and warranties of this Agreement shall inure to the benefit of each of the
foregoing, and shall bind the representatives, successors and assigns of each
Assignor. Except as set forth below in this Section 9, any and all disputes,
controversies and claims that any Assignor may assert against Laurus arising out
of or relating to this Master Security Agreement or any other Document shall be
determined exclusively by arbitration (each such arbitration, an "Arbitration")
in New York City before a panel of three neutral arbitrators agreed to by Laurus
and the Company (collectively, the "Arbitrators") in accordance with and
pursuant to the then existing commercial arbitration rules of the American
Arbitration Association. Each Assignor hereby irrevocably waives any right to
assert such claims in any other forum. The Arbitrators shall have the power in
their discretion to award specific performance or injunctive relief (but shall
not have the power to render any incidental, special or punitive damages) and
reasonable attorneys' fees and expenses to any party in any arbitration. The
Arbitrators may not change, modify or alter any express condition, term or
provision of this Master Security Agreement or of any other Document nor shall
they have the power to render any award against Laurus that would have such
effect. Each Arbitration award shall be final and binding upon the parties
subject thereto and judgment may be entered thereon in any court of competent
jurisdiction. The service of any notice, process, motion or other document in
connection with an Arbitration or for the enforcement of any Arbitration award
may be made in the same manner as communications may be given under Section 10
hereof. Notwithstanding the foregoing, the provisions of this Section 9 nor any
other provision contained in this Master Security Agreement or in any other
Document shall limit in any manner whatsoever the Laurus' right to commence an
action against or in connection with any Assignor or their respective properties
in any court of competent jurisdiction or otherwise utilize judicial process in
connection with or arising out of Laurus' rights and remedies under this Master
Security Agreement and/or any other Document or otherwise (any such action, a
"Court Action"). Court Actions may be brought by Laurus in any state or federal
court of competent jurisdiction and each Assignor irrevocably submits to the
jurisdiction of such state and federal courts and irrevocably waives any claim
or defense of inconvenient forum or lack of personal jurisdiction in such forum
or right of removal or right to jury trial under any applicable law or decision
or otherwise. Service of any notice, process, motion or other document in
connection with a Court Action may be made in the same manner as communications
may be given under Section 10. In addition, Laurus may serve process in any
other manner permitted under applicable law.

         32.      All notices from Laurus to any Assignor shall be sufficiently
given if mailed or delivered to such Assignor's address set forth below.

                  11.      It is understood and agreed that any person or entity
         that desires to become an Assignor hereunder, or is required to execute
         a counterpart of this Master Security Agreement after the date hereof
         pursuant to the requirements of any Document, shall become an Assignor
         hereunder by (x) executing a Joinder Agreement in form and substance
         satisfactory to Laurus, (y) delivering supplements to such exhibits and
         annexes to such Documents as Laurus shall reasonably request and (z)
         taking all actions as specified in this Master Security Agreement as
         would have been taken by such Assignor had it been an original party to
         this Master Security Agreement, in each case with all documents
         required above to be delivered to Laurus and with all documents and
         actions required above to be taken to the reasonable satisfaction of
         Laurus.

                  12.      Notwithstanding anything to the contrary contained in
         this Master Security Agreement, the terms and conditions of this Master
         Security Agreement shall be subject in all respects to the terms and
         conditions of the Intercreditor Agreement. In the event that the terms
         and conditions of this Master Security Agreement are in contravention
         of the terms and conditions of the Intercreditor Agreement, the terms
         and conditions of the Intercreditor Agreement shall prevail. No
         provision of this Master Security Agreement shall be amended, modified,
         supplemented, restated, terminated or waived in any respect except by a
         writing duly executed by each Assignor and Laurus.
