         (other than Common Stock) and other securities of the Company or any
         other person (corporate or otherwise) which the holder of the Warrant
         at any time shall be entitled to receive, or shall have received, on
         the exercise of the Warrant, in lieu of or in addition to Common Stock,
         or which at any time shall be issuable or shall have been issued in

         VOXX shares of Common Stock issued and outstanding on the date of such
         exercise (calculated on a fully diluted basis and, in any event,
         assuming the full conversion or exercise, as the case may be, of all
         securities issued by the Company which are convertible or exercisable
         into Common Stock).

         126.     Exercise of Warrant.

                  126.1    Number of Shares Issuable upon Exercise. From and
after the date hereof through and including the Expiration Date, the Holder
shall be entitled to receive, upon exercise of this Warrant in whole or in part,

attached hereto as Exhibit A (the "Exercise Notice"), shares of Common Stock of
the Company, subject to adjustment pursuant to Section 4.

                  126.2    Fair Market Value. For purposes hereof, the "Fair
Market Value" of a share of Common Stock as of a particular date (the
"Determination Date") shall mean:

                  (a)      If the Company's Common Stock is traded on the
         American Stock Exchange or another national exchange or is quoted on
         the National or SmallCap Market of The Nasdaq Stock Market,
         Inc.("Nasdaq"), then the closing or last sale price, respectively,
         reported for the last business day immediately preceding the
         Determination Date.

                  (b)      If the Company's Common Stock is not traded on the
         American Stock Exchange or another national exchange or on the Nasdaq
         but is traded on the NASD OTC Bulletin Board, then the mean of the
         average of the closing bid and asked prices reported for the last
         business day immediately preceding the Determination Date.

                  (c)      Except as provided in clause (d) below, if the
         Company's Common Stock is not publicly traded, then as the Holder and
         the Company agree or in the absence of agreement by arbitration in
         accordance with the rules then in effect of the American Arbitration
         Association, before a single arbitrator to be chosen from a panel of
         persons qualified by education and training to pass on the matter to be
         decided.

<PAGE>

                  (d)      If the Determination Date is the date of a
         liquidation, dissolution or winding up, or any event deemed to be a
         liquidation, dissolution or winding up pursuant to the Company's
         charter, then all amounts to be payable per share to holders of the
         Common Stock pursuant to the charter in the event of such liquidation,
         dissolution or winding up, plus all other amounts to be payable per
         share in respect of the Common Stock in liquidation under the charter,
         assuming for the purposes of this clause (d) that all of the shares of
         Common Stock then issuable upon exercise of the Warrant are outstanding
         at the Determination Date.

                  126.3    Company Acknowledgment. The Company will, at the time
of the exercise of the Warrant, upon the request of the holder hereof
acknowledge in writing its continuing obligation to afford to such holder any
rights to which such holder shall continue to be entitled after such exercise in
accordance with the provisions of this Warrant. If the holder shall fail to make
any such request, such failure shall not affect the continuing obligation of the
Company to afford to such holder any such rights.

                  126.4    Trustee for Warrant Holders. In the event that a bank
or trust company shall have been appointed as trustee for the holders of the
Warrant pursuant to Subsection 3.2, such bank or trust company shall have all
the powers and duties of a warrant agent (as hereinafter described) and shall
accept, in its own name for the account of the Company or such successor person
as may be entitled thereto, all amounts otherwise payable to the Company or such
successor, as the case may be, on exercise of this Warrant pursuant to this
Section 1.

         127.     Procedure for Exercise.

                  127.1    Delivery of Stock Certificates, Etc., on Exercise.
The Company agrees that the shares of Common Stock purchased upon exercise of
this Warrant shall be deemed to be issued to the Holder as the record owner of
such shares as of the close of business on the date on which this Warrant shall
have been surrendered and payment made for such shares in accordance herewith.
As soon as practicable after the exercise of this Warrant in full or in part,
and in any event within three (3) business days thereafter, the Company at its
expense (including the payment by it of any applicable issue taxes) will cause
to be issued in the name of and delivered to the Holder, or as such Holder (upon
payment by such Holder of any applicable transfer taxes) may direct in
compliance with applicable securities laws, a certificate or certificates for
the number of duly and validly issued, fully paid and nonassessable shares of
Common Stock (or Other Securities) to which such Holder shall be entitled on
such exercise, plus, in lieu of any fractional share to which such holder would
otherwise be entitled, cash equal to such fraction multiplied by the then Fair
Market Value of one full share, together with any other stock or other
securities and property (including cash, where applicable) to which such Holder
is entitled upon such exercise pursuant to Section 1 or otherwise.

<PAGE>

                  127.2    Exercise. Payment may be made either (i) in cash or
by certified or official bank check payable to the order of the Company equal to
the applicable aggregate Exercise Price, (ii) by delivery of the Warrant, or
shares of Common Stock and/or Common Stock receivable upon exercise of the
Warrant in accordance with Section (b) below, or (iii) by a combination of any
of the foregoing methods, for the number of Common Shares specified in such
Exercise Notice (as such exercise number shall be adjusted to reflect any
adjustment in the total number of shares of Common Stock issuable to the Holder
per the terms of this Warrant) and the Holder shall thereupon be entitled to
receive the number of duly authorized, validly issued, fully-paid and
non-assessable shares of Common Stock (or Other Securities) determined as
provided herein. Notwithstanding any provisions herein to the contrary, if the
Fair Market Value of one share of Common Stock is greater than the Exercise
Price (at the date of calculation as set forth below), in lieu of exercising
this Warrant for cash, the Holder may elect to receive shares equal to the value
(as determined below) of this Warrant (or the portion thereof being exercised)
by surrender of this Warrant at the principal office of the Company together
with the properly endorsed Exercise Notice in which event the Company shall
issue to the Holder a number of shares of Common Stock computed using the
following formula:

         X=Y            (A-B)
                      ---------
                          A

         Where X =   the number of shares of Common Stock to be issued to
                     the Holder

         Y =         the number of shares of Common Stock purchasable
                     under the Warrant or, if only a portion of the
                     Warrant is being exercised, the portion of the
                     Warrant being exercised (at the date of such
                     calculation)

         A =         the Fair Market Value of one share of the Company's
                     Common Stock (at the date of such calculation)

         B =         Exercise Price (as adjusted to the date of such
                     calculation)

         128.     Effect of Reorganization, Etc.; Adjustment of Exercise Price.

                  128.1    Reorganization, Consolidation, Merger, Etc. In case
at any time or from time to time, the Company shall (a) effect a reorganization,
(b) consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and
adequate provision shall be made by the Company whereby the Holder of this
Warrant, on the exercise hereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such Holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
Holder had so exercised this Warrant, immediately prior thereto, all subject to
further adjustment thereafter as provided in Section 4.

                  128.2    Dissolution. In the event of any dissolution of the
Company following the transfer of all or substantially all of its properties or
assets, the Company, concurrently with any distributions made to holders of its
Common Stock, shall at its expense deliver or cause to be delivered to the
Holder the stock and other securities and property (including cash, where
applicable) receivable by the Holder of the Warrant pursuant to Section 3.1, or,
if the Holder shall so instruct the Company, to a bank or trust company
specified by the Holder and having its principal office in New York, NY as
trustee for the Holder of the Warrant (the "Trustee").

<PAGE>

                  128.3    Continuation of Terms. Upon any reorganization,
consolidation, merger or transfer (and any dissolution following any transfer)
referred to in this Section 3, this Warrant shall continue in full force and
effect and the terms hereof shall be applicable to the shares of stock and other
securities and property receivable on the exercise of this Warrant after the
consummation of such reorganization, consolidation or merger or the effective
date of dissolution following any such transfer, as the case may be, and shall
be binding upon the issuer of any such stock or other securities, including, in
the case of any such transfer, the person acquiring all or substantially all of
the properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in Section 4. In the
event this Warrant does not continue in full force and effect after the
consummation of the transactions described in this Section 3, then the Company's
securities and property (including cash, where applicable) receivable by the
Holders of the Warrant will be delivered to Holder or the Trustee as
contemplated by Section 3.2.

         129.     Extraordinary Events Regarding Common Stock. In the event that
the Company shall (a) issue additional shares of the Common Stock as a dividend
or other distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such
event, the Exercise Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Exercise Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Exercise Price then in effect. The
Exercise Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 4.
The number of shares of Common Stock that the holder of this Warrant shall
thereafter, on the exercise hereof as provided in Section 1, be entitled to
receive shall be increased to a number determined by multiplying the number of
shares of Common Stock that would otherwise (but for the provisions of this
Section 4) be issuable on such exercise by a fraction of which (a) the numerator
is the Exercise Price that would otherwise (but for the provisions of this
Section 4) be in effect, and (b) the denominator is the Exercise Price in effect
on the date of such exercise.

<PAGE>

         130.     Certificate as to Adjustments. In each case of any adjustment
or readjustment in the shares of Common Stock (or Other Securities) issuable on
the exercise of the Warrant, the Company at its expense will promptly cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or readjustment in accordance with the terms of the Warrant and prepare a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based, including a
statement of (a) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold, (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding, and (c) the Exercise Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant. The Company will forthwith
mail a copy of each such certificate to the holder of the Warrant and any
Warrant agent of the Company (appointed pursuant to Section 11 hereof).

         131.     Reservation of Stock, Etc., Issuable on Exercise of Warrant.
The Company will at all times reserve and keep available, solely for issuance
and delivery on the exercise of the Warrant, shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of the Warrant.

         132.     Assignment; Exchange of Warrant. Subject to compliance with
applicable securities laws, this Warrant, and the rights evidenced hereby, may
be transferred by any registered holder hereof (a "Transferor") in whole or in
part. On the surrender for exchange of this Warrant, with the Transferor's
endorsement in the form of Exhibit B attached hereto (the "Transferor
Endorsement Form") and together with evidence reasonably satisfactory to the
Company demonstrating compliance with applicable securities laws, which shall
include, without limitation, the provision of a legal opinion from the
Transferor's counsel (at the Company's expense) that such transfer is exempt
from the registration requirements of applicable securities laws, and with
payment by the Transferor of any applicable transfer taxes) will issue and
deliver to or on the order of the Transferor thereof a new Warrant of like
tenor, in the name of the Transferor and/or the transferee(s) specified in such
Transferor Endorsement Form (each a "Transferee"), calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant so surrendered by the Transferor.

         133.     Replacement of Warrant. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such loss, theft or destruction of this
Warrant, on delivery of an indemnity agreement or security reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of this Warrant, the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

         134.     Registration Rights. The Holder of this Warrant has been
granted certain registration rights by the Company. These registration rights
are set forth in a Registration Rights Agreement entered into by the Company and
Purchaser dated as of even date of this Warrant.

<PAGE>

         135.     [Intentionally Deleted]

         136.     Warrant Agent. The Company may, by written notice to the each
Holder of the Warrant, appoint an agent for the purpose of issuing Common Stock
(or Other Securities) on the exercise of this Warrant pursuant to Section 1,
exchanging this Warrant pursuant to Section 7, and replacing this Warrant
pursuant to Section 8, or any of the foregoing, and thereafter any such
issuance, exchange or replacement, as the case may be, shall be made at such
office by such agent.

         137.     Transfer on the Company's Books. Until this Warrant is
transferred on the books of the Company, the Company may treat the registered
holder hereof as the absolute owner hereof for all purposes, notwithstanding any
notice to the contrary.

         138.     Notices, Etc. All notices and other communications from the
Company to the Holder of this Warrant shall be mailed by first class registered
or certified mail, postage prepaid, at such address as may have been furnished
to the Company in writing by such Holder or, until any such Holder furnishes to
the Company an address, then to, and at the address of, the last Holder of this
Warrant who has so furnished an address to the Company.

<PAGE>

         139.     Miscellaneous. This Warrant and any term hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of such change, waiver, discharge
or termination is sought. This Warrant shall be governed by and construed in
accordance with the laws of State of New York without regard to principles of
conflicts of laws. Except as set forth below in this Section 15, any and all
disputes, controversies and claims that the Company may assert against the any
Holder arising out of or relating to this Warrant 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 the Purchaser and
the Company (collectively, the "Arbitrators") in accordance with and pursuant to
the then existing commercial arbitration rules of the American Arbitration
Association. The Company 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 Warrant nor shall they have the power to render any award
against any Holder 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 13 hereof. Notwithstanding the
foregoing, the provisions of this Section 15 nor any other provision contained
in this Warrant shall limit in any manner whatsoever any Holder's right to
commence an action against or in connection with the Company or its properties
in any court of competent jurisdiction or otherwise utilize judicial process in
connection with or arising out of any Holder's rights and remedies under this
Warrant or otherwise (any such action, a "Court Action"). Court Actions may be
brought by any Holder in any state or federal court of competent jurisdiction
and the Company 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 13. In
addition, any Holder may serve process in any other manner permitted under
applicable law. The individuals executing this Warrant on behalf of the Company
agree to waive trial by jury. The prevailing party shall be entitled to recover
from the other party its reasonable attorney's fees and costs. In the event that
any provision of this Warrant is invalid or unenforceable under any applicable
statute or rule of law, then such provision shall be deemed inoperative to the
extent that it may conflict therewith and shall be deemed modified to conform
with such statute or rule of law. Any such provision which may prove invalid or
unenforceable under any law shall not affect the validity or enforceability of
any other provision of this Warrant. The headings in this Warrant are for
purposes of reference only, and shall not limit or otherwise affect any of the
terms hereof. The invalidity or unenforceability of any provision hereof shall
in no way affect the validity or enforceability of any other provision hereof.
The Company acknowledges that legal counsel participated in the preparation of
this Warrant and, therefore, stipulates that the rule of construction that
ambiguities are to be resolved against the drafting party shall not be applied
in the interpretation of this Warrant to favor any party against the other
party.
