         Subsidiaries has violated any of the patents, trademarks, service
         marks, trade names, copyrights or trade secrets or other proprietary
         rights of any other person or entity, nor is the Company or any of its

compliance with this Agreement and the Related Agreements to which it is a
party, and the issuance and sale of the Note by the Company and the other
Securities by the Company each pursuant hereto and thereto, will not, with or

of the Company or any of its Subsidiaries, nor any consultant with whom the
Company or any of its Subsidiaries has contracted, is in violation of any term
of any employment contract, proprietary information agreement or any other
agreement relating to the right of any such individual to be employed by, or to
contract with, the Company or any of its Subsidiaries because of the nature of
the business to be conducted by the Company or any of its Subsidiaries; and to
the Company's knowledge the continued employment by the Company or any of its
Subsidiaries of its present employees, and the performance of the Company's and
its Subsidiaries' contracts with its independent contractors, will not result in
any such violation. Neither the Company nor any of its Subsidiaries is aware
that any of its employees is obligated under any contract (including licenses,
covenants or commitments of any nature) or other agreement, or subject to any
judgment, decree or order of any court or administrative agency, that would
interfere with their duties to the Company or any of its Subsidiaries. Neither

of the Company and its Subsidiaries has all material franchises, permits,
licenses and any similar authority necessary for the conduct of its business as

nor any other document delivered by the Company or any of its Subsidiaries to
Purchaser or its attorneys or agents in connection herewith or therewith or with
the transactions contemplated hereby or thereby, contain any untrue statement of
a material fact nor omit to state a material fact necessary in order to make the
statements contained herein or therein, in light of the circumstances in which

assumptions of fact and opinion as to future events which the Company or any of
its Subsidiaries, at the date of the issuance of such projections or estimates,
believed to be reasonable.

                  4.20 Insurance. Each of the Company and each of its
Subsidiaries has general commercial, product liability, fire and casualty
insurance policies with coverages which the Company believes are customary for

each SEC Report was, at the time of its filing, in substantial compliance with
the requirements of its respective form and none of the SEC Reports, nor the
financial statements (and the notes thereto) included in the SEC Reports, as of
their respective filing dates, contained any untrue statement of a material fact
or omitted to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading.

                  6.8 Insurance. Each of the Company and its Subsidiaries will
keep its assets which are of an insurable character insured by financially sound
and reputable insurers against loss or damage by fire, explosion and other risks
customarily insured against by companies in similar business similarly situated
as the Company and its Subsidiaries; and the Company and its Subsidiaries will
maintain, with financially sound and reputable insurers, insurance against other
hazards and risks and liability to persons and property to the extent and in the
manner which the Company reasonably believes is customary for companies in

businesses similar to the Company's or the respective Subsidiary's insuring

business; and (v) furnish Purchaser with (x) copies of all policies and evidence
of the maintenance of such policies at least thirty (30) days before any
expiration date, (y) excepting the Company's workers' compensation policy,
endorsements to such policies naming Purchaser as "co-insured" or "additional
insured" and appropriate loss payable endorsements in form and substance
satisfactory to Purchaser, naming Purchaser as loss payee, and (z) evidence that
as to Purchaser the insurance coverage shall not be impaired or invalidated by
any act or neglect of the Company or any Subsidiary and the insurer will provide
Purchaser with at least thirty (30) days notice prior to cancellation. The
Company and each Subsidiary shall instruct the insurance carriers that in the
event of any loss thereunder, the carriers shall make payment for such loss to
the Company and/or the Subsidiary and Purchaser jointly. In the event that as of
the date of receipt of each loss recovery upon any such insurance, the Purchaser
has not declared an event of default with respect to this Agreement or any of
the Related Agreements, then the Company and/or such Subsidiary shall be
permitted to direct the application of such loss recovery proceeds toward
investment in property, plant and equipment that would comprise "Collateral"
secured by Purchaser's security interest pursuant to its security agreement,
with any surplus funds to be applied toward payment of the obligations of the
Company to Purchaser. In the event that Purchaser has properly declared an event
of default with respect to this Agreement or any of the Related Agreements, then
all loss recoveries received by Purchaser upon any such insurance thereafter may
be applied to the obligations of the Company hereunder and under the Related
Agreements, in such order as the Purchaser may determine. Any surplus (following
satisfaction of all Company obligations to Purchaser) shall be paid by Purchaser
to the Company or applied as may be otherwise required by law. Any deficiency
thereon shall be paid by the Company or the Subsidiary, as applicable, to
Purchaser, on demand.

franchises and all licenses and other rights to use Intellectual Property owned
or possessed by it and reasonably deemed to be necessary to the conduct of its
business.

                  6.10 Properties. Each of the Company and each of its
Subsidiaries will keep its properties in good repair, working order and
condition, reasonable wear and tear excepted, and from time to time make all
needful and proper repairs, renewals, replacements, additions and improvements
thereto; and each of the Company and each of its Subsidiaries will at all times
comply with each provision of all leases to which it is a party or under which
it occupies property if the breach of such provision could, either individually
or in the aggregate, reasonably be expected tohave a Material Adverse Effect.

         proceeds of an initial public offering of the VOXX Common Stock or (b)
         the conversion thereof into VOXX Common Stock in connection with (but
         not prior to the VOXX IPO Date (as defined in the Note)) an initial

         and are not exercisable at a price per share of Voxx Common Stock less
         than or equal to $2.23 (as adjusted proportionately for any stock

         (capitalized or otherwise) incurred by the Company or any of its

         or replaced, and (z) any debt incurred in connection with the purchase
         of assets in the ordinary course of business, or any refinancings or
         replacements thereof on terms no less favorable to the Purchaser than
         the indebtedness being refinanced or replaced; (ii) cancel any debt
         owing to it in excess of $50,000 in the aggregate during any 12 month
         period; (iii) assume, guarantee, endorse or otherwise become directly
         or contingently liable in connection with any obligations of any other

         business or guarantees of indebtedness otherwise permitted to be
         outstanding pursuant to this clause (e);

                  (f) create or acquire any Subsidiary after the date hereof
         unless (i) such Subsidiary is a wholly-owned Subsidiary of EPXR and

         agreement in respect thereof) and/or, if requested by the Purchaser
         with respect to entities located outside of the United States, the
         foreign equivalent of any such agreement or guaranty (it being
         understood that the terms and conditions of any such foreign equivalent
         shall be satisfactory to the Purchaser), and, to the extent required by
         the Purchaser, satisfies each condition of this Agreement and the
         Related Agreements as if such Subsidiary were a Subsidiary of EPXR on
         the Closing Date; and

                  (g) (i) make, or permit any of its Subsidiaries which are
         Credit Parties to make, any investments in, or any loans or advances
         to, any Subsidiary of EPXR which is not a Credit Party, other than, so
         long as no Event of Default (as defined in the Note) has occurred and

         the ordinary course of business or (ii) transfer, or permit any
         Subsidiary of EPXR which is a Credit Party to transfer, assets to any

         no Event of Default has occurred and is continuing, immaterial asset
         transfers made in the ordinary course of business.

         For the purposes of this Agreement, "Credit Party" shall mean (x) EPXR
and each Subsidiary of EPXR organized in the United States of America that is
party to the Master Security Agreement, the Stock Pledge Agreement and the
Subsidiary Guaranty and (y) Epixtar Phillippines IT-Enabled Services
Corporation, a corporation organized under the laws of the Phillippines
("Epixtar Phillippines") and each other wholly-owned Subsidiary of the Company
that is organized outside of the United States of America that has executed the
Foreign Documentation referred to in Section 6.16 (it being understood and
agreed that an Immaterial Subsidiary shall be deemed a Credit Party for purposes
of this definition following the execution by such Immaterial Subsidiary of an
assumption or joinder agreement with respect to the Master Security Agreement,
the Subsidiary Guaranty and the Stock Pledge Agreement).

                  6.13 Reissuance of Securities. The Company agrees to reissue
certificates representing the Securities without the legends set forth in
Section 5.7 above at such time as:

                  (a) the holder thereof is permitted to dispose of such
         Securities pursuant to Rule 144(k) under the Securities Act; or

                  (b) upon resale subject to an effective registration statement
         after such Securities are registered under the Securities Act.

The Company agrees to cooperate with the Purchaser in connection with all
resales pursuant to Rule 144(d) and Rule 144(k) and provide legal opinions
necessary to allow such resales provided the Company and its counsel receive
reasonably requested representations from the selling Purchaser and broker, if
any.

                  6.14 Opinion. On the Closing Date, the Company will deliver to
the Purchaser an opinion acceptable to the Purchaser from the Company's external
legal counsel. The Company will provide, at the Company's expense, such other
legal opinions in the future as are deemed reasonably necessary by the Purchaser
(and acceptable to the Purchaser) in connection with the conversion of the Note
and exercise of the Option and the Warrant.

                  6.15 Margin Stock. The Company will not permit any of the
proceeds of the Note, the Warrant or the Option to be used directly or
indirectly to "purchase" or "carry" "margin stock" or to repay indebtedness
incurred to "purchase" or "carry" "margin stock" within the respective meanings
of each of the quoted terms under Regulation U of the Board of Governors of the
Federal Reserve System as now and from time to time hereafter in effect.

                  6.16 Foreign Security. No later than 20 days following the
Closing Date hereunder, the Company shall cause Epixtar Phillippines, each other
applicable Subsidiary of the Company and any other third party requested by the
Purchaser to enter into such security and guaranty documentation governed by
laws of the Phillippines as is requested by the Purchaser, with such
documentation to be in form and substance satisfactory to the Purchaser. No
later than 60 days following a request by the Purchaser, the Company shall cause
each Subsidiary organized in a jurisdiction outside of the United States
(collectively, the "Foreign Subsidiaries"), other than an Immaterial Subsidiary,
to execute such guaranty and security documentation governed by the jurisdiction
of organization of such Subsidiary (the "Foreign Documentation") as the
Purchaser deems necessary or desirable. All such Foreign Documentation shall be
in form and substance satisfactory to the Purchaser, and the Company agrees to
cause the respective Foreign Subsidiary to deliver all such other documentation
as is requested by the Purchaser in connection with the execution and delivery
of such Foreign Documentation (including, without limitation, an opinion of
counsel satisfactory to the Purchaser). Furthermore, it is hereby agreed that
the Company shall not permit any equity interests of any Foreign Subsidiary (or
any parent thereof) to be transferred to any person or other entity that is not
a Credit Party until such time as the Foreign Subsidiaries have become party to
the Foreign Documentation required to be entered into pursuant to this Section
6.16. The Company shall reimburse the Purchaser for any and all legal fees and
other expenses incurred by the Purchaser in connection with the preparation,
execution, negotiation and delivery of the Foreign Documentation.

                  6.17 Financing Right of First Refusal.

                  (a) The Company hereby grants to the Purchaser a right of
first refusal to provide any Bridge Loan Indebtedness to be issued by the
Company and/or any of its Subsidiaries, subject to the following terms and
conditions. From and after the date hereof, prior to the incurrence of any
Bridge Loan Indebtedness, the Company and/or any Subsidiary of the Company, as
the case may be, shall notify the Purchaser of its intention to enter into such
Bridge Loan Indebtedness. In connection therewith, the Company and/or the
applicable Subsidiary thereof shall submit a fully executed term sheet (a
"Proposed Term Sheet") to the Purchaser setting forth the terms, conditions and
pricing of any such Bridge Loan Indebtedness (such financing to be negotiated on
"arm's length" terms and the terms thereof to be negotiated in good faith)
proposed to be entered into by the Company and/or such Subsidiary. The Purchaser
shall have the right, but not the obligation, to deliver its own proposed term
sheet (the "Purchaser Term Sheet") setting forth the terms and conditions upon
which the Purchaser would be willing to provide such Bridge Loan Indebtedness to
the Company and/or such Subsidiary. The Purchaser Term Sheet shall contain terms
no less favorable to the Company and/or such Subsidiary than those outlined in
Proposed Term Sheet. The Purchaser shall deliver such Purchaser Term Sheet
within five business days of receipt of each such Proposed Term Sheet. If the
provisions of the Purchaser Term Sheet are at least as favorable to the Company
and/or such Subsidiary, as the case may be, as the provisions of the Proposed
Term Sheet, the Company and/or such Subsidiary shall enter into and consummate
the Bridge Loan Indebtedness transaction outlined in the Purchaser Term Sheet.

                  (b) The Company will not, and will not permit its Subsidiaries
to, agree, directly or indirectly, to any restriction with any person or entity
which limits the ability of the Purchaser to consummate a Bridge Loan
Indebtedness transaction or any other additional financing with the Company or
any of its Subsidiaries.

                  6.18 Issuance of Voxx Common Stock. Notwithstanding anything
to the contrary contained in this Agreement, EPXR and Voxx hereby agree that it
shall not (or shall not permit, as the case may be) any share of Voxx Common
Stock (or any securities convertible or exercisable into shares of Voxx Common
Stock) to be issued, or agree to issue any share of Voxx Common Stock (or any
securities convertible or exercisable into shares of Voxx Common Stock), in any
case, at a price less than or equal to $2.23 per share.

         7. Covenants of the Purchaser. The Purchaser covenants and agrees with
the Company as follows:

                  7.1 Confidentiality. The Purchaser agrees that it will not
disclose, and will not include in any public announcement, the name of the
Company, unless expressly agreed to by the Company or unless and until such
disclosure is required by law or applicable regulation, and then only to the
extent of such requirement.

                  7.2 Non-Public Information. The Purchaser agrees not to effect
any sales in the shares of the Company's Common Stock while in possession of
material, non-public information regarding the Company if such sales would
violate applicable securities law.

                  7.3 Limitation on Acquisition of Common Stock of the Company.
Notwithstanding anything to the contrary contained in this Agreement, any
Ancillary Agreement or any document, instrument or agreement entered into in
connection with any other transactions between the Purchaser and the Company,
the Purchaser may not acquire stock in the Company (including, without
limitation, pursuant to a contract to purchase, by exercising an option or
warrant, by converting any other security or instrument, by acquiring or
exercising any other right to acquire, shares of stock or other security
convertible into shares of stock in the Company, or otherwise, and such
contracts, options, warrants, conversion or other rights shall not be
enforceable or exercisable) to the extent such stock acquisition would cause any
interest (including any original issue discount) payable by the Company to
Laurus not to qualify as "portfolio interest" within the meaning of Section
881(c)(2) of the Code, by reason of Section 881(c)(3) of the Code, taking into
account the constructive ownership rules under Section 871(h)(3)(C) of the Code
(the "Stock Acquisition Limitation"). The Stock Acquisition Limitation shall
automatically become null and void without any notice to the Company upon the
earlier to occur of either (a) the Company's delivery to the Purchaser of a
Notice of Redemption (as defined in the Note) or (b) the existence of an Event
of Default (as defined in the Note) at a time when the average closing price of
the Company's common stock as reported by Bloomberg, L.P. on the Principal
Market for the immediately preceding five trading days is greater than or equal
to 150% of the Fixed Conversion Price (as defined in the Note).

         8. Covenants of the Company and Purchaser Regarding Indemnification.

                  8.1 Company Indemnification. The Company agrees to indemnify,
hold harmless, reimburse and defend the Purchaser, each of the Purchaser's
officers, directors, agents, affiliates, control persons, and principal
shareholders, against any claim, cost, expense, liability, obligation, loss or
damage (including reasonable legal fees) of any nature, incurred by or imposed
upon the Purchaser which results, arises out of or is based upon: (i) any
misrepresentation by the Company or any of its Subsidiaries or breach of any
warranty by the Company or any of its Subsidiaries in this Agreement, any
Related Agreement or in any exhibits or schedules attached hereto or thereto; or
(ii) any breach or default in performance by Company or any of its Subsidiaries
of any covenant or undertaking to be performed by Company or any of its
Subsidiaries hereunder, under any other Related Agreement or any other agreement
entered into by the Company and/or any of its Subsidiaries and Purchaser
relating hereto or thereto.

                                       24
<PAGE>

                  8.2 Purchaser's Indemnification. Purchaser agrees to
indemnify, hold harmless, reimburse and defend the Company and each of the
Company's officers, directors, agents, affiliates, control persons and principal
shareholders, at all times against any claim, cost, expense, liability,
obligation, loss or damage (including reasonable legal fees) of any nature,
incurred by or imposed upon the Company which results, arises out of or is based
upon: (i) any misrepresentation by Purchaser or breach of any warranty by
Purchaser in this Agreement or in any exhibits or schedules attached hereto or
any Related Agreement; or (ii) any breach or default in performance by Purchaser
of any covenant or undertaking to be performed by Purchaser hereunder, or any
other agreement entered into by the Company and Purchaser relating hereto.

         9.       Conversion of Convertible Note.

                  9.1      Mechanics of Conversion.

                  (a) Provided the Purchaser has notified the Company of the
         Purchaser's intention to sell the Note Shares and the Note Shares are
         included in an effective registration statement or are otherwise exempt
         from registration when sold: (i) upon the conversion of the Note or
         part thereof, the Company shall, at its own cost and expense, take all
         necessary action (including the issuance of an opinion of counsel
         reasonably acceptable to the Purchaser following a request by the
         Purchaser) to assure that the Company's transfer agent shall issue
         shares of the Company's Common Stock in the name of the Purchaser (or
         its nominee) or such other persons as designated by the Purchaser in
         accordance with Section 9.1(b) hereof and in such denominations to be
         specified representing the number of Note Shares issuable upon such
         conversion; and (ii) the Company warrants that no instructions other
         than these instructions have been or will be given to the transfer
         agent of the Company's Common Stock and that after the Effectiveness
         Date (as defined in the respective Registration Rights Agreement) the
         Note Shares issued will be freely transferable subject to the
         prospectus delivery requirements of the Securities Act and the
         provisions of this Agreement, and will not contain a legend restricting
         the resale or transferability of the Note Shares.

                  (b) Purchaser will give notice of its decision to exercise its
         right to convert the Note or part thereof by telecopying or otherwise
         delivering an executed and completed notice of the number of shares to
         be converted to the Company (the "Notice of Conversion"). The Purchaser
         will not be required to surrender the Note until the Purchaser receives
         a credit to the account of the Purchaser's prime broker through the
         DWAC system (as defined below), representing the Note Shares or until
         the Note has been fully satisfied. Each date on which a Notice of
         Conversion is telecopied or delivered to the Company in accordance with
         the provisions hereof shall be deemed a "Conversion Date." Pursuant to
         the terms of the Notice of Conversion, the Company will issue
         instructions to the transfer agent accompanied by an opinion of counsel
         within one (1) business day of the date of the delivery to the Company
         of the Notice of Conversion and shall cause the transfer agent to
         transmit the certificates representing the Conversion Shares to the
         Purchaser by crediting the account of the Purchaser's prime broker with
         the Depository Trust Company ("DTC") through its Deposit Withdrawal
         Agent Commission ("DWAC") system within three (3) business days after
         receipt by the Company of the Notice of Conversion (the "Delivery
         Date").

                                       25
<PAGE>

                  (c) The Company understands that a delay in the delivery of
         the Note Shares in the form required pursuant to Section 9 hereof
         beyond the Delivery Date could result in economic loss to the
         Purchaser. In the event that the Company fails to direct its transfer
         agent to deliver the Note Shares to the Purchaser via the DWAC system
         within the time frame set forth in Section 9.1(b) above and the Note
         Shares are not delivered to the Purchaser by the Delivery Date, as
         compensation to the Purchaser for such loss, the Company agrees to pay
         late payments to the Purchaser for late issuance of the Note Shares in
         the form required pursuant to Section 9 hereof upon conversion of the
         Note in the amount equal to the greater of: (i) $500 per business day
         after the Delivery Date; or (ii) the Purchaser's actual damages from
         such delayed delivery. Notwithstanding the foregoing, the Company will
         not owe the Purchaser any late payments if the delay in the delivery of
         the Note Shares beyond the Delivery Date is solely out of the control
         of the Company and the Company is actively trying to cure the cause of
         the delay. The Company shall pay any payments incurred under this
         Section in immediately available funds upon demand and, in the case of
         actual damages, accompanied by reasonable documentation of the amount
         of such damages. Such documentation shall show the number of shares of
         Common Stock the Purchaser is forced to purchase (in an open market
         transaction) which the Purchaser anticipated receiving upon such
         conversion, and shall be calculated as the amount by which (A) the
         Purchaser's total purchase price (including customary brokerage
         commissions, if any) for the shares of Common Stock so purchased
         exceeds (B) the aggregate principal and/or interest amount of the Note,
         for which such Conversion Notice was not timely honored.

Nothing contained herein or in any document referred to herein or delivered in
connection herewith shall be deemed to establish or require the payment of a
rate of interest or other charges in excess of the maximum permitted by
applicable law. In the event that the rate of interest or dividends required to
be paid or other charges hereunder exceed the maximum amount permitted by such
law, any payments in excess of such maximum shall be credited against amounts
owed by the Company to a Purchaser and thus refunded to the Company.

         10.      Registration Rights.

                  10.1 Registration Rights Granted. The Company hereby grants
registration rights to the Purchaser pursuant to a Registration Rights Agreement
dated as of even date herewith between the Company and the Purchaser.

                                       26
<PAGE>

                  10.2 Offering Restrictions. Except as previously disclosed in
the SEC Reports or in the Exchange Act Filings, or stock or stock options
granted to employees or directors of the Company (these exceptions hereinafter
referred to as the "Excepted Issuances"), neither the Company nor any of its
Subsidiaries will issue any securities with a continuously variable/floating
conversion feature which are or could be (by conversion or registration)
free-trading securities (i.e. common stock subject to a registration statement)
prior to the full repayment or conversion of the Note (together with all accrued
and unpaid interest and fees related thereto) (the "Exclusion Period"), provided
that a securities with a variable/floating rate conversion feature that is not
less than the Fixed Conversion Price (as defined in the Note) shall be
permitted.

         11.      Miscellaneous.

                  11.1 Governing Law. THIS AGREEMENT AND EACH RELATED AGREEMENT

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 11.8. IN
ADDITION, THE PURCHASER MAY SERVE PROCESS IN ANY OTHER MANNER PERMITTED UNDER

MAY PROVE INVALID OR UNENFORCEABLE UNDER ANY LAW SHALL NOT AFFECT THE VALIDITY
OR ENFORCEABILITY OF ANY OTHER PROVISION OF THIS AGREEMENT OR ANY RELATED
AGREEMENT.

impaired thereby.

omission to exercise any right, power or remedy accruing to any party, upon any
breach, default or noncompliance by another party under this Agreement or the
Related Agreements, shall impair any such right, power or remedy, nor shall it
be construed to be a waiver of any such breach, default or noncompliance, or any
acquiescence therein, or of or in any similar breach, default or noncompliance
thereafter occurring. All remedies, either under this Agreement or the Related
Agreements, by law or otherwise afforded to any party, shall be cumulative and

THIS NOTE (THE "NOTE") AND THE COMMON SHARES ISSUABLE UPON CONVERSION OF THIS
NOTE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
ANY STATE SECURITIES LAWS. THIS NOTE AND THE COMMON SHARES ISSUABLE UPON

                          SECURED CONVERTIBLE TERM NOTE

         FOR VALUE RECEIVED, EPIXTAR CORP., a Florida corporation ("EPXR"), and
VOXX CORPORATION, a Florida corporation ("VOXX") (EPXR and VOXX, collectively,
the "BORROWER"), jointly and severally hereby promise to pay to LAURUS MASTER
FUND, LTD., c/o M&C Corporate Services Limited, P.O. Box 309 GT, Ugland House,
South Church Street, George Town, Grand Cayman, Cayman Islands, Fax:
345-949-8080 (the "HOLDER") or its registered assigns or successors in interest
the sum of Five Million Five Hundred Thousand Dollars ($5,500,000), together
with any accrued and unpaid interest hereon, on April 29, 2008 (the "MATURITY
DATE") if not sooner paid.

         Capitalized terms used herein without definition shall have the
meanings ascribed to such terms in that certain Securities Purchase Agreement
dated as of the date hereof between the Borrower and the Holder (the "PURCHASE
AGREEMENT").

The following terms shall apply to this Note:

<PAGE>

                                    ARTICLE I
                             INTEREST & AMORTIZATION

         1.1 Interest Rate. Subject to Sections 4.11 and 5.6 hereof, interest
payable on this shall accrue at a rate per annum (the "Interest Rate") equal to
the "prime rate" published in The Wall Street Journal from time to time, plus
two percent (2.00%). The prime rate shall be increased or decreased as the case
may be for each increase or decrease in the prime rate in an amount equal to
such increase or decrease in the prime rate; each change to be effective as of
the day of the change in such rate. Interest shall be (i) calculated on the
basis of a 360 day year and payable monthly, in arrears, commencing on June 1,
2005 and on the first business day of each consecutive calendar month thereafter
until the Maturity Date (and on the Maturity Date), whether by acceleration or
otherwise (each, a "REPAYMENT DATE").

         1.2 Minimum Monthly Principal Payments. Amortizing payments of the
aggregate principal amount outstanding under this Note at any time (the
"PRINCIPAL AMOUNT") shall begin on November 1, 2005 and shall recur on the first
business day of each succeeding month thereafter until the Maturity Date (each,
an "AMORTIZATION DATE"). Subject to Article 3 below, beginning on the first
Amortization Date, the Borrower shall make monthly payments to the Holder on
each Repayment Date, each in the amount of $130,952.38 (the "MONTHLY PRINCIPAL
AMOUNT"), together with any accrued and unpaid interest to date on such portion
of the Principal Amount (as defined below) plus any and all other amounts which
are then owing under this Note, the Purchase Agreement or any other Related
Agreement but have not been paid (the Monthly Principal Amount, together with
such accrued and unpaid interest and such other amounts, collectively, the
"MONTHLY AMOUNT"). Any Principal Amount that remains outstanding on the Maturity
Date shall be due and payable on the Maturity Date.

                                   ARTICLE II
                              CONVERSION REPAYMENT

         2.1 Payment of Monthly Amount in Cash or Common Stock. (a) If the
Monthly Amount is required to be paid in shares of Common Stock (as defined
below) pursuant to Section 2.1(b), each month by the fifth (5th) business day
prior to each Amortization Date (the "NOTICE DATE"), the Holder shall, subject
to Section 2.2 below and the other provisions of this Note, deliver to Borrower
a written notice in the form of Exhibit B attached hereto converting the Monthly
Amount payable on the next Amortization Date or Repayment Date, as the case may
be, into freely tradable unrestricted shares of common stock of EPXR ("EPXR
COMMON STOCK") or, following the satisfaction of each of the conditions set
forth in clause (i) of Section 2.2 below, into freely tradable unrestricted
shares of common stock of VOXX ("VOXX COMMON STOCK") (EPXR Common Stock and VOXX
Common Stock, collectively, the "Common Stock") (each, a "REPAYMENT NOTICE"). If
a Repayment Notice is not delivered by the Holder on or before the applicable
Notice Date for such Amortization Date (or is not required to be delivered in
accordance with Section 2.1(b)), then the Borrower shall pay the Monthly Amount
due on such Amortization Date in cash. Any portion of the Monthly Amount paid in
cash on a Amortization Date or Repayment Date, as the case may be, shall be paid
to the Holder an amount equal to 102% of the principal portion of the Monthly
Amount due and owing to Holder on such Amortization Date or Repayment Date. If
the Holder converts all or a portion of the Monthly Amount in shares of Common
Stock as provided herein, the number of such shares to be issued by the Borrower
to the Holder on such Amortization Date or Repayment Date, as the case may be,
shall be the number determined by dividing (x) the portion of the Monthly Amount
to be paid in shares of Common Stock, by (y) the then applicable Fixed
Conversion Price. For purposes hereof, the "FIXED CONVERSION PRICE" shall,
subject to further adjustment as provided herein, mean (x) in the case of a
conversion into EPXR Common Stock, $1.00 and (y) in the case of a conversion
into VOXX Common Stock on or after the date of the consummation of an initial
public offering of the VOXX Common Stock (the "VOXX IPO DATE"), a price equal to
85% of the offering price of the VOXX Common Stock on the VOXX IPO Date (after
giving effect thereto).

<PAGE>

         (b) Monthly Amount Conversion Guidelines. Subject to Sections 2.1(a),
2.2, and 3.2 hereof, the Holder shall convert all or a portion of the Monthly
Amount due on each Repayment Date in shares of Common Stock if the average
closing price of the Common Stock as reported by Bloomberg, L.P. on the
Principal Market for the five (5) trading days immediately preceding such
Repayment Date was greater than or equal to 110% of the Fixed Conversion Price,
provided, however, that such conversions shall not exceed twenty five percent
(25%) of the aggregate dollar trading volume of the Common Stock for the five
(5) day trading period immediately preceding delivery of a Notice of Conversion
to the Borrower. Any part of the Monthly Amount due on a Amortization Date or
Repayment Date, as the case may be, that the Holder has not converted into
shares of Common Stock shall be paid by the Borrower in cash on such
Amortization Date or Repayment Date. Any part of the Monthly Amount due on such
Amortization Date or Repayment Date which must be paid in cash (as a result of
the closing price of the Common Stock on one or more of the five (5) trading
days preceding the applicable Amortization Date or Repayment Date being less
than 110% of the Fixed Conversion Price) shall be paid in cash at the rate of
102% of the Monthly Amount otherwise due on such Amortization Date or Repayment
Date, within three (3) business days of the applicable Amortization Date or
Repayment Date.

         2.2 No Effective Registration. Notwithstanding anything to the
contrary herein, absent the express written consent of the Holder, none of the
Borrower's obligations to the Holder may be converted into VOXX Common Stock or
EPXR Common Stock unless and until (i) in the case of conversion into VOXX
Common Stock, either (I) (a) VOXX shall have consummated an initial public
offering, (b)VOXX Common Stock shall be publicly traded on a nationally
recognized exchange; and (c) the shares underlying the conversion of this Note
into VOXX Common Stock pursuant to the terms hereof shall have been registered
on an effective, current Registration Statement (as defined in the Registration
Rights Agreement) or (II) an exemption from registration of the Voxx Common
Stock (with respect to the resale of such common stock) is available to pursuant
to Rule 144 of the Securities Act; (ii) in the case of conversion into EPXR
Common Stock, (a) the shares underlying the conversion of this Note into EPXR
Common Stock pursuant to the terms hereof shall have been registered on an
effective, current Registration Statement; or (b) an exemption from registration
of the EPXR Common Stock (with respect to the resale of such common stock) is
available to pursuant to Rule 144 of the Securities Act and (iii) in each of the
foregoing cases, no Event of Default hereunder or under any Related Agreement
exists and is continuing, unless such Event of Default is cured within any
applicable cure period or is otherwise waived in writing by the Holder in whole
or in part at the Holder's option.

<PAGE>

         2.3 Optional Redemption in Cash. The Borrower will have the option of
prepaying this Note ("OPTIONAL REDEMPTION") by paying to the Holder a sum of
money equal to one hundred thirty percent (130%) of the outstanding principal
amount of this Note at the time of prepayment, together with accrued but unpaid
interest thereon and any and all other sums due, accrued or payable to the
Holder arising under this Note, the Purchase Agreement or any Related Agreement
(the "REDEMPTION AMOUNT") outstanding on the day written notice of redemption
(the "NOTICE OF REDEMPTION") is given to the Holder. The Notice of Redemption
shall specify the date for such Optional Redemption (the "REDEMPTION PAYMENT
DATE") which date shall be seven (7) business days after the date of the Notice
of Redemption (the "REDEMPTION PERIOD"). A Notice of Redemption shall not be
effective with respect to any portion of this Note for which the Holder has a
pending election to convert pursuant to Section 3.1, or for conversions
initiated or made by the Holder pursuant to Section 3.1 during the Redemption
Period. The Redemption Amount shall be determined as if such Holder's conversion
elections had been completed immediately prior to the date of the Notice of
Redemption. On the Redemption Payment Date, the Redemption Amount must be paid
in good funds to the Holder. In the event the Borrower fails to pay the
Redemption Amount on the Redemption Payment Date as set forth herein, then such
Redemption Notice will be null and void.

                                   ARTICLE III
                                CONVERSION RIGHTS

         3.1. Holder's Conversion Rights. The Holder shall have the right, but
not the obligation, to convert all or any portion of the then aggregate
outstanding principal amount of this Note, together with interest and fees due
hereon, into shares of Common Stock subject to the terms and conditions set
forth in this Article III. The Holder may exercise such right by delivery to the
Borrower of a written notice of conversion not less than one (1) day prior to
the date upon which such conversion shall occur.

         22.14 3.2 Conversion Limitation. Notwithstanding anything contained
herein to the contrary, the Holder shall not be entitled to convert pursuant to
the terms of this Note an amount that would be convertible into that number of
Conversion Shares which would exceed the difference between the number of shares
of Common Stock beneficially owned by such Holder or issuable upon exercise of
warrants held by such Holder and 4.99% of the outstanding shares of Common Stock
of the Borrower. For the purposes of the immediately preceding sentence,
beneficial ownership shall be determined in accordance with Section 13(d) of the
Exchange Act and Regulation 13d-3 thereunder. The Holder may void the Conversion
Share limitation described in this Section 3.2 upon 75 days prior notice to the
Borrower or without any notice requirement upon an Event of Default.

<PAGE>

         22.15

         22.16 3.3 Mechanics of Holder's Conversion. (a) In the event that
the Holder elects to convert this Note into Common Stock, the Holder shall give
notice of such election by delivering an executed and completed notice of
conversion ("NOTICE OF CONVERSION") to the Borrower and such Notice of
Conversion shall provide a breakdown in reasonable detail of the Principal
Amount, accrued interest and fees being converted. On each Conversion Date (as
hereinafter defined) and in accordance with its Notice of Conversion, the Holder
shall make the appropriate reduction to the Principal Amount, accrued interest
and fees as entered in its records and shall provide written notice thereof to
the Borrower within two (2) business days after the Conversion Date. Each date
on which a Notice of Conversion is delivered or telecopied to the Borrower in
accordance with the provisions hereof shall be deemed a Conversion Date (the
"CONVERSION DATE"). A form of Notice of Conversion to be employed by the Holder
is annexed hereto as Exhibit A.

         22.17 (b) Pursuant to the terms of the Notice of Conversion, the
Borrower will issue instructions to the transfer agent accompanied by an opinion
of counsel within two (2) business day of the date of the delivery to Borrower
of the Notice of Conversion and shall cause the transfer agent to transmit the
certificates representing the Conversion Shares to the Holder by crediting the
account of the Holder's designated broker with the Depository Trust Corporation
("DTC") through its Deposit Withdrawal Agent Commission ("DWAC") system within
three (3) business days after receipt by the Borrower of the Notice of
Conversion (the "DELIVERY DATE"). In the case of the exercise of the conversion
rights set forth herein the conversion privilege shall be deemed to have been
exercised and the Conversion Shares issuable upon such conversion shall be
deemed to have been issued upon the date of receipt by the Borrower of the
Notice of Conversion. The Holder shall be treated for all purposes as the record
holder of such Common Stock, unless the Holder provides the Borrower written
instructions to the contrary.

         3.4 Conversion Mechanics.

         (a) The number of shares of Common Stock to be issued upon each
conversion of this Note shall be determined by dividing that portion of the
principal and interest and fees to be converted, if any, by the then applicable
Fixed Conversion Price. In the event of any conversions of outstanding principal
amount under this Note in part pursuant to this Article III, such conversions
shall be deemed to constitute conversions of outstanding principal amount
applying to Monthly Amounts for the remaining Amortization Dates in
chronological order.

<PAGE>

         (b) The Fixed Conversion Price and number and kind of shares or other
securities to be issued upon conversion is subject to adjustment from time to
time upon the occurrence of certain events, as follows:

         A. Stock Splits, Combinations and Dividends. If the shares of Common
Stock are subdivided or combined into a greater or smaller number of shares of
Common Stock, or if a dividend is paid on the Common Stock in shares of Common
Stock, the Fixed Conversion Price or the Conversion Price, as the case may be,
shall be proportionately reduced in case of subdivision of shares or stock
dividend or proportionately increased in the case of combination of shares, in
each such case by the ratio which the total number of shares of Common Stock
outstanding immediately after such event bears to the total number of shares of
Common Stock outstanding immediately prior to such event.

         B. During the period the conversion right exists, the Borrower will
reserve from its authorized and unissued Common Stock a sufficient number of
shares to provide for the issuance of Common Stock upon the full conversion of
this Note. The Borrower represents that upon issuance, such shares will be duly
and validly issued, fully paid and non-assessable. The Borrower agrees that its
issuance of this Note shall constitute full authority to its officers, agents,
and transfer agents who are charged with the duty of executing and issuing stock
certificates to execute and issue the necessary certificates for shares of
Common Stock upon the conversion of this Note.

         C. Share Issuances. Subject to the provisions of this Section 3.4, if
the Borrower shall (x) in the case of EPXR Common Stock, at any time prior to
the conversion or repayment in full of the Principal Amount and (y) in the case
of VOXX Common Stock at any time after the VOXX IPO Date and prior to the
conversion or repayment in full of the Principal Amount, issue any shares of
Common Stock or securities convertible into Common Stock to a person other than
the Holder (except (i) pursuant to Subsections A or B above; (ii) pursuant to
options, warrants, or other obligations to issue shares outstanding on the date
hereof as disclosed to Holder in writing; or (iii) pursuant to options that may
be issued under any employee incentive stock option and/or any qualified stock
option plan adopted by the Borrower) for a consideration per share (the "Offer
Price") less than the Fixed Conversion Price in effect at the time of such
issuance (any such issuance, an "Offering"), then the Fixed Conversion Price
shall be immediately reset to such lower Offer Price at the time of issuance of
such securities pursuant to the formula below. For purposes hereof, the issuance
of any security of the Borrower convertible into or exercisable or exchangeable
for Common Stock shall result in an adjustment to the Fixed Conversion Price at
the time of issuance of such securities.

                  If the Borrower issues any additional shares pursuant to
Section 3.4 above then, and thereafter successively upon each such issue, the
Fixed Conversion Price shall be adjusted by multiplying the then applicable
Fixed Conversion Price by the following fraction:

<PAGE>

           ----------------------------------------
                            A + B
           ----------------------------------------
               (A + B) + [((C - D) x B) / C]
           ----------------------------------------

            A = Total amount of shares convertible pursuant to this Note, the
Purchase Agreement and the Related Agreements.

            B =  Actual shares sold in the Offering

            C = Fixed Conversion Price
            D = Offering price

         D. Reclassification, etc. If the Borrower at any time shall, by
reclassification or otherwise, change the Common Stock into the same or a
different number of securities of any class or classes, this Note, as to the
unpaid Principal Amount and accrued interest thereon, shall thereafter be deemed
to evidence the right to purchase an adjusted number of such securities and kind
of securities as would have been issuable as the result of such change with
respect to the Common Stock immediately prior to such reclassification or other
change.

         3.5 Issuance of New Note. Upon any partial conversion of this Note, a
new Note containing the same date and provisions of this Note shall, at the
request of the Holder, be issued by the Borrower to the Holder for the principal
balance of this Note and interest which shall not have been converted or paid.
The Borrower will pay no costs, fees or any other consideration to the Holder
for the production and issuance of a new Note.

           Upon the occurrence and continuance of an Event of Default beyond any
applicable grace period, the Holder may make all sums of principal, interest and
other fees then remaining unpaid hereon and all other amounts payable hereunder
immediately due and payable. In the event of such an acceleration, the amount
due and owing to the Holder shall be 110% of the outstanding principal amount of
the Note (plus accrued and unpaid interest and fees, if any) (the "DEFAULT
PAYMENT"). If, with respect to any Event of Default, the Borrower cures the
Event of Default, the Event of Default will be deemed to no longer exist and any
rights and remedies of Holder pertaining to such Event of Default will be of no
further force or effect. The Default Payment shall be applied first to any fees
due and payable to Holder pursuant to this Note, the Purchase Agreement or the
other Related Agreements, then to accrued and unpaid interest due on this Note
and then to outstanding principal balance of this Note.

         The occurrence of any of the following events set forth in Sections 4.1

         4.3 Breach of Representations and Warranties. Any representation or
warranty made by the Borrower in this Note or the Purchase Agreement, or by the

case, be false or misleading in any material respect on the date that such
representation or warranty was made or deemed made.

cases a suspension of all trading on a Principal Market, provided that the
Borrower shall not have been able to cure such trading suspension within thirty

Market within sixty (60) days of such notice. The "Principal Market" for the
Common Stock shall include the NASD OTC Bulletin Board, NASDAQ SmallCap Market,
NASDAQ National Market System, American Stock Exchange, or New York Stock
Exchange (whichever of the foregoing is at the time the principal trading
exchange or market for the Common Stock, or any securities exchange or other

         4.8 Failure to Deliver Common Stock or Replacement Note. The Borrower

are defined in Sections 13(d) and 14(d) of the Exchange Act, as in effect on the
date hereof), other than the Holder, is or becomes the "beneficial owner" (as

         5.1 Failure or Indulgence Not Waiver. No failure or delay on the part
of the Holder hereof in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of

otherwise available.

<PAGE>

         5.3 Amendment Provision. The term "Note" and all reference thereto,
as used throughout this instrument, shall mean this instrument as originally
executed, or if later amended or supplemented, then as so amended or
supplemented, and any successor instrument issued pursuant to Section 3.5
hereof, as it may be amended or supplemented.

         5.4 Assignability. This Note shall be binding upon the Borrower and
its successors and assigns, and shall inure to the benefit of the Holder and its
successors and assigns, and may be assigned by the Holder in accordance with the
requirements of the Purchase Agreement. This Note shall not be assigned by the
Borrower without the consent of the Holder.

         5.5 Governing Law. This Note shall be governed by and construed in
accordance with the laws of the State of New York, without regard to principles
of conflicts of laws. Except as set forth below in this Section 5.5, any and all
disputes, controversies and claims that the Borrower or any of its Subsidiaries
may assert against the Holder arising out of or relating to this Note, the
Purchase Agreement or any other Related Agreement 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 Holder and the
Borrower (collectively, the "Arbitrators") in accordance with and pursuant to
the then existing commercial arbitration rules of the American Arbitration
Association. The Borrower (on its behalf and on behalf of its subsidiaries)
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 Note, the Purchase
Agreement or of any other Related Agreement nor shall they have the power to
render any award against the 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 5.2 hereof.
Notwithstanding the foregoing, the provisions of this Section 5.5 nor any other
provision contained in this Note, the Purchase Agreement or in any other Related
Agreement shall limit in any manner whatsoever the Holder's right to commence an
action against or in connection with the Borrower, any of its Subsidiaries or
their respective properties in any court of competent jurisdiction or otherwise
utilize judicial process in connection with or arising out of the Holder's
rights and remedies under this Note, the Purchase Agreement and/or any Related
Agreement or otherwise (any such action, a "Court Action"). Court Actions may be
brought by the Holder in any state or federal court of competent jurisdiction
and the Borrower (on its behalf and on behalf of its Subsidiaries) 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 5.2. In addition, the Holder
may serve process in any other manner permitted under applicable law. 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
Note 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 unenforceability of any other provision
of this Note. Nothing contained herein shall be deemed or operate to preclude
the Holder from bringing suit or taking other legal action against the Borrower
in any other jurisdiction to collect on the Borrower's obligations to Holder, to
realize on any collateral or any other security for such obligations, or to
enforce a judgment or other court in favor of the Holder.

<PAGE>

         5.6 Maximum Payments. Nothing contained herein shall be deemed to
establish or require the payment of a rate of interest or other charges in
excess of the maximum permitted by applicable law. In the event that the rate of
interest required to be paid or other charges hereunder exceed the maximum
permitted by such law, any payments in excess of such maximum shall be credited
against amounts owed by the Borrower to the Holder and thus refunded to the
Borrower.

         5.7 Security Interest and Guarantee. The Holder has been granted a
security interest (i) in certain assets of EPXR and its Subsidiaries as more
fully described in the Master Security Agreement dated as of the date hereof and
(ii) pursuant to the Stock Pledge Agreement dated as of the date hereof. The
obligations of the Borrower under this Note are guaranteed by EPXR and certain
Subsidiaries of EPXR pursuant to the Guaranty dated as of the date hereof.

         5.8 Construction. Each party acknowledges that its legal counsel
participated in the preparation of this Note 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 Note to favor any party
against the other.

         5.9 Cost of Collection. If default is made in the payment of this
Note, the Borrower shall pay to Holder reasonable costs of collection, including
reasonable attorney's fees.

         5.10 Joint and Several Obligations. All obligations of VOXX and EPXR
as co-borrowers under this Note and the Related Agreements (the "Obligations")
shall be joint and several obligations, and the Borrower shall make payment upon
the maturity of the Obligations by acceleration or otherwise, and such
obligation and liability on the part of the Borrower shall in no way be affected
by any extensions, renewals and forbearance granted by the Holder to the
Borrower, failure of Holder to give either EPXR or VOXX any notice, any failure
of Holder to pursue to preserve its rights against either EPXR and/or VOXX, the
release by Holder of any collateral now or thereafter acquired from either EPXR,
VOXX and/or any other subsidiary of EPXR, and such agreement by each of EPXR and
VOXX to pay upon any notice issued pursuant thereto is unconditional and
unaffected by prior recourse by Holder to either EPXR, VOXX, or any other
subsidiary of EPXR or any collateral for the Obligations or the lack thereof.
Each of EPXR and VOXX expressly waives any and all rights of subrogation,
reimbursement, indemnity, exoneration, contribution or any other claim which
each of EPXR and/or VOXX may now or hereafter have against the other or other
person or entity directly or contingently liable for the Obligations, or against
or with respect to any other's property (including, without limitation, any
property which is collateral for the Obligations), arising from the existence or
performance of this Note, the Purchase Agreement or any other Related Agreement,
until all Obligations have been indefeasibly paid in full and this Note, the
Purchase Agreement and the other Related Agreements have been irrevocably
terminated.
