                             STOCK PLEDGE AGREEMENT

         This Stock Pledge Agreement (this "Agreement"), dated as of April 29,
2005, among Sands Brothers Venture Capital LLC, Sands Brothers Venture Capital
II LLC, Sands Brothers Venture Capital III LLC and Sands Brothers Venture
Capital IV LLC (these Sands entities collectively, the "Pledgees"), Epixtar
Corp., a Florida corporation (the "Company"), and each of the other undersigned
pledgors (the Company and each such other undersigned pledgor, a "Pledgor" and
collectively, the "Pledgors").

                                   BACKGROUND

         Each of the Company, Voxx Corporation, a Florida corporation ("Voxx"),
and the Pledgees has entered into a Securities Purchase Agreement, dated as of
the date hereof (as amended, modified, restated or supplemented from time to
time, the "Securities Purchase Agreement"), pursuant to which the Pledgees
provide or will provide certain financial accommodations to the Company.

         In order to induce the Pledgees to provide or continue to provide the
financial accommodations described in the Securities Purchase Agreement, each
Pledgor has agreed to pledge and grant a security interest in the collateral
described herein to the Pledgees on the terms and conditions set forth herein.

         NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration the receipt of which is hereby acknowledged, the parties
hereto agree as follows:

         19. Defined Terms. All capitalized terms used herein which are not
defined shall have the meanings given to them in the Securities Purchase
Agreement.

         20. Pledge and Grant of Security Interest. To secure the full and
punctual payment and performance of (the following clauses (a) and (b),
collectively, the "Indebtedness") (a) the obligations under the Securities
Purchase Agreement and the Related Agreements referred to in the Securities
Purchase Agreement (the Securities Purchase Agreement and the Related
Agreements, as each may be amended, restated, modified and/or supplemented from
time to time, collectively, the "Documents") and (b) all other indebtedness,
obligations and liabilities of each Pledgor and/or any other subsidiary of the
Company to the Pledgees, whether now existing or hereafter arising, direct or
indirect, liquidated or unliquidated, absolute or contingent, due or not due and
whether under, pursuant to or evidenced by a note, agreement, guaranty,
instrument or otherwise (in each case, irrespective of the genuineness,
validity, regularity or enforceability of such Indebtedness, or of any
instrument evidencing any of the Indebtedness or of any collateral therefor or
of the existence or extent of such collateral, and irrespective of the
allowability, allowance or disallowance of any or all of such in any case
commenced by or against any Pledgor under Title 11, United States Code,
including, without limitation, obligations or indebtedness of each Pledgor
and/or any other subsidiary of the Company for post-petition interest, fees,
costs and charges that would have accrued or been added to the Indebtedness but
for the commencement of such case, and irrespective of the allowability,
allowance or disallowance of such post-petition interest, fees, costs and
charges), each Pledgor hereby pledges, assigns, hypothecates, transfers and
grants a security interest to Pledgees in all of the following (the
"Collateral"):

<PAGE>

             (a) the shares of stock set forth on Schedule A annexed hereto
(which shall explicitly exclude the shares of Epixtar Marketing Corp., a Florida
corporation, until such time as such shares are released from the escrow
arrangement by and between the Company and the previous owners thereof) and
expressly made a part hereof (together with any additional shares of stock or
other equity interests acquired by any Pledgor after the date hereof, the
"Pledged Stock"), the certificates representing the Pledged Stock and all
dividends, cash, instruments and other property or proceeds from time to time
received, receivable or otherwise distributed in respect of or in exchange for
any or all of the Pledged Stock;

             (b) all additional shares of stock of any issuer (each, an
"Issuer") of the Pledged Stock from time to time acquired by any Pledgor in any
manner, including, without limitation, stock dividends or a distribution in
connection with any increase or reduction of capital, reclassification, merger,
consolidation, sale of assets, combination of shares, stock split, spin-off or
split-off (which shares shall be deemed to be part of the Collateral), and the
certificates representing such additional shares, and all dividends, cash,
instruments and other property or proceeds from time to time received,
receivable or otherwise distributed in respect of or in exchange for any or all
of such shares; and

             (c) all options and rights, whether as an addition to, in
substitution of or in exchange for any shares of any Pledged Stock and all
dividends, cash, instruments and other property or proceeds from time to time
received, receivable or otherwise distributed in respect of or in exchange for
any or all such options and rights.

Notwithstanding the foregoing or anything to the contrary contained herein, it
is understood and agreed by the parties hereto that the term "Indebetedness"
shall not include any principal amount of indebtedness in excess of an aggregate
amount of $1,500,000 and the rate of interest and fees related to the
Indebtedness, which such interest and fees shall not exceed the rate of interest
and fees provided for in the Documents (as in effect on the date hereof).

         21. Delivery of Collateral. All certificates representing or evidencing
the Pledged Stock shall be delivered to and held by or on behalf of Pledgees
pursuant hereto and shall be accompanied by duly executed instruments of
transfer or assignment in blank, all in form and substance satisfactory to
Laurus Master Fund, Ltd. a Cayman Islands company acting as collateral agent for
itself and for the benefit of the Pledgees ("Laurus"). Each Pledgor hereby
authorizes the Issuer upon demand by the Pledgees to deliver any certificates,
instruments or other distributions issued in connection with the Collateral
directly to Laurus, in each case to be held by Laurus, subject to the terms
hereof. Upon an Event of Default (as defined below) under the Note that has
occurred and is continuing beyond any applicable grace period, Laurus shall have
the right, during such time in its discretion and without notice to the Pledgor,
to transfer to or to register in the name of the Laurus or any of its nominees
any or all of the Pledged Stock. In addition, the Laurus shall have the right at
such time to exchange certificates or instruments representing or evidencing
Pledged Stock for certificates or instruments of smaller or larger
denominations.

         22. Representations and Warranties of each Pledgor. Each Pledgor
jointly and severally represents and warrants to the Pledgees (which
representations and warranties shall be deemed to continue to be made until all
of the Indebtedness has been paid in full and each Document and each agreement
and instrument entered into in connection therewith has been irrevocably
terminated) that:

             (a) the execution, delivery and performance by each Pledgor of this
Agreement and the pledge of the Collateral hereunder do not and will not result

decree, order, law, statute, ordinance or other governmental rule or regulation
applicable to any Pledgor;

             (b) this Agreement constitutes the legal, valid, and binding
obligation of each Pledgor enforceable against each Pledgor in accordance with
its terms;

             (c) (i) all Pledged Stock owned by each Pledgor is set forth on

each share of the Pledged Stock;

             (d) all of the shares of the Pledged Stock have been duly

             (e) no consent or approval of any person, corporation, governmental

execution, delivery and performance of this Agreement, (ii) the exercise by the
Pledgees of any rights with respect to the Collateral or (iii) the pledge and
assignment of, and the grant of a security interest in, the Collateral
hereunder;

             (f) there are no pending or, to the best of Pledgor's knowledge,
threatened actions or proceedings before any court, judicial body,
administrative agency or arbitrator which may materially adversely affect the
Collateral;

             (g) each Pledgor has the requisite power and authority to enter
into this Agreement and to pledge and assign the Collateral to the Pledgees in
accordance with the terms of this Agreement.

<PAGE>

             (h) each Pledgor owns each item of the Collateral and, except for
encumbrances securing (x) the Indebtedness and (ii) the Laurus Obligations (as
defined in the Intercreditor Agreement), the Collateral shall be, immediately
following the closing of the transactions contemplated by the Documents, free
and clear of any other security interest, pledge, claim, lien, charge,
hypothecation, assignment, offset or encumbrance whatsoever (collectively,
"Liens").

             (i) there are no restrictions on transfer of the Pledged Stock
contained in the certificate of incorporation or by-laws (or equivalent
organizational documents) of the Issuer or otherwise which have not otherwise
been enforceably and legally waived by the necessary parties.

             (j) none of the Pledged Stock has been issued or transferred in
violation of the securities registration, securities disclosure or similar laws
of any jurisdiction to which such issuance or transfer may be subject.

             (k) the pledge and assignment of the Collateral and the grant of a
security interest under this Agreement vest in the Pledgees all rights of each
Pledgor in the Collateral as contemplated by this Agreement.

             (l) The Pledged Stock constitutes one hundred percent (100%) of the
issued and outstanding shares of capital stock of each Issuer, other than Voxx
Corporation, of which Epixtar Corp. owns the outstanding shares set forth on
Schedule A hereto.

         23. Covenants. Each Pledgor jointly and severally covenants that, until
the Indebtedness shall be satisfied in full and each Document and each agreement
and instrument entered into in connection therewith is irrevocably terminated:

             (a) Other than the issuances to the Laurus Creditors (as defined in
the Intercreditor Agreement) that are contemplated by the Laurus Documents (as
defined in the Intercreditor Agreement) and/or issuances to the Sands Creditors
(as defined in the Intercreditor Agreement) that are contemplated by the Sands
Documents (as defined in the Intercreditor Agreement), no Pledgor will sell,
assign, transfer, convey, or otherwise dispose of, or agree to sell, assign,
transfer, convey or otherwise dispose of, its rights in or to the Collateral or
any interest therein; nor will any Pledgor create, incur or permit to exist any
Lien whatsoever with respect to any of the Collateral or the proceeds thereof
other than that created hereby.

             (b) Each Pledgor will, at its expense, defend Pledgees's right,
title and security interest in and to the Collateral against the claims of any
other party.

             (c) Each Pledgor shall at any time, and from time to time, upon the
written request of Pledgees, execute and deliver such further documents and do
such further acts and things as Pledgees may reasonably request in order to
effect the purposes of this Agreement including, but without limitation,
delivering to Pledgees upon the occurrence of an Event of Default irrevocable
proxies in respect of the Collateral in form satisfactory to Pledgees. Until
receipt thereof, upon an Event of Default that has occurred and is continuing
beyond any applicable grace period, this Agreement shall constitute Pledgor's
proxy to Pledgees or its nominee to vote all shares of Collateral then
registered in each Pledgor's name.

<PAGE>

             (d) Other than the issuances to the Laurus Creditors (as defined in
the Intercreditor Agreement) that are contemplated by the Laurus Documents (as
defined in the Intercreditor Agreement) and/or issuances to the Sands Creditors
(as defined in the Intercreditor Agreement) that are contemplated by the Sands
Documents (as defined in the Intercreditor Agreement) or (iii) issuances to the
creditors in respect of the Bridge Loan Indebtedness in accordance with the
terms set forth in Section 6.12(e)(i)(v) of the Securities Purchase Agreement,
no Pledgor will consent to or approve the issuance of (i) any additional shares
of any class of capital stock or other equity interests of the Issuer; or (ii)
any securities convertible either voluntarily by the holder thereof or
automatically upon the occurrence or nonoccurrence of any event or condition
into, or any securities exchangeable for, any such shares, unless, in either
case, such shares are pledged as Collateral pursuant to this Agreement;
provided, however, in the case of an initial public offering by Voxx, the
issuance by Voxx of shares of its Common Stock will be permitted without the
requirement that such shares be pledged as additional collateral under this
Agreement.

         24. Voting Rights and Dividends. In addition to the Pledgees's rights
and remedies set forth in Section 8 hereof, in case an Event of Default shall
have occurred and be continuing, beyond any applicable cure period, the Pledgees
shall (i) be entitled to vote the Collateral, (ii) be entitled to give consents,
waivers and ratifications in respect of the Collateral (each Pledgor hereby
irrevocably constituting and appointing the Pledgees, with full power of
substitution, the proxy and attorney-in-fact of each Pledgor for such purposes)
and (iii) be entitled to collect and receive for its own use cash dividends paid
on the Collateral. No Pledgor shall be permitted to exercise or refrain from
exercising any voting rights or other powers if, in the reasonable judgment of
the Pledgees, such action would have a material adverse effect on the value of
the Collateral or any part thereof; and, provided, further, that following the
occurrence and during the continuance of any Event of Default beyond any
applicable grace period, each Pledgor shall give at least five (5) days' written
notice of the manner in which such Pledgor intends to exercise, or the reasons
for refraining from exercising, any voting rights or other powers other than
with respect to any election of directors and voting with respect to any
incidental matters. Following the occurrence and during the continuance of an
Event of Default beyond any applicable grace period, all dividends and all other
distributions in respect of any of the Collateral, shall be delivered to the
Pledgees to hold as Collateral and shall, if received by any Pledgor, be
received in trust for the benefit of the Pledgees, be segregated from the other
property or funds of any other Pledgor, and be forthwith delivered to the
Pledgees as Collateral in the same form as so received (with any necessary
endorsement).

<PAGE>

         25. Event of Default. An Event of Default shall be deemed to have
occurred and may be declared by the Pledgees upon the happening of any of the
following events:

             (a) An "Event of Default" under any Document or any agreement or
note related to any Document shall have occurred and be continuing beyond any
applicable cure period;

             (b) Any Pledgor shall default in the performance of any of its
obligations under any agreement between any Pledgor and Pledgees, including,
without limitation, this Agreement, and such default shall not be cured for a
period of thirty (30) days after the occurrence thereof;

             (c) Any representation or warranty of any Pledgor made herein, in
any Document or in any agreement, statement or certificate given in writing
pursuant hereto or thereto or in connection herewith or therewith shall be false
or misleading in any material respect and shall not be cured for a period of
thirty (30) days after the occurrence thereof;

             (d) Any portion of the Collateral is subjected to levy of
execution, attachment, distraint or other judicial process; or any portion of
the Collateral is the subject of a claim (other than by the Pledgees) of a Lien
or other right or interest in or to the Collateral and such levy or claim shall
not be cured, disputed or stayed within a period of thirty (30) business days
after the occurrence thereof; or

             (e) Any Pledgor shall (i) apply for, consent to, or suffer to exist
the appointment of, or the taking of possession by, a receiver, custodian,
trustee, liquidator or other fiduciary of itself or of all or a substantial part
of its property, (ii) make a general assignment for the benefit of creditors,
(iii) commence a voluntary case under any state or federal bankruptcy laws (as
now or hereafter in effect), (iv) be adjudicated a bankrupt or insolvent, (v)
file a petition seeking to take advantage of any other law providing for the
relief of debtors, (vi) acquiesce to, or fail to have dismissed, within
forty-five (45) days, any petition filed against it in any involuntary case
under such bankruptcy laws, or (vii) take any action for the purpose of
effecting any of the foregoing.

         26. Remedies. In case an Event of Default shall have occurred and be
declared by the Pledgees, the Pledgees may:

             (a) Transfer any or all of the Collateral into their names, or into
the name of their nominee or nominees;

             (b) Exercise all corporate rights with respect to the Collateral
including, without limitation, all rights of conversion, exchange, subscription
or any other rights, privileges or options pertaining to any shares of the
Collateral as if it were the absolute owner thereof, including, but without
limitation, the right to exchange, at its discretion, any or all of the
Collateral upon the merger, consolidation, reorganization, recapitalization or
other readjustment of the Issuer thereof, or upon the exercise by the Issuer of
any right, privilege or option pertaining to any of the Collateral, and, in
connection therewith, to deposit and deliver any and all of the Collateral with
any committee, depository, transfer agent, registrar or other designated agent
upon such terms and conditions as it may determine, all without liability except
to account for property actually received by it; and

<PAGE>

             (c) Subject to any requirement of applicable law, sell, assign and
deliver the whole or, from time to time, any part of the Collateral at the time
held by the Pledgees, at any private sale or at public auction, with or without
demand, advertisement or notice of the time or place of sale or adjournment
thereof or otherwise (all of which are hereby waived, except such notice as is
required by applicable law and cannot be waived), for cash or credit or for
other property for immediate or future delivery, and for such price or prices
and on such terms as the Pledgees in its sole discretion may determine, or as
may be required by applicable law.

             Each Pledgor hereby waives and releases any and all right or equity
of redemption, whether before or after sale hereunder. At any such sale, unless
prohibited by applicable law, the Pledgees may bid for and purchase the whole or
any part of the Collateral so sold free from any such right or equity of
redemption. All moneys received by the Pledgees hereunder whether upon sale of
the Collateral or any part thereof or otherwise shall be held by the Pledgees
and applied by them as provided in Section 10 hereof. No failure or delay on the
part of the Pledgees in exercising any rights hereunder shall operate as a
waiver of any such rights nor shall any single or partial exercise of any such
rights preclude any other or future exercise thereof or the exercise of any
other rights hereunder. The Pledgees shall have no duty as to the collection or
protection of the Collateral or any income thereon nor any duty as to
preservation of any rights pertaining thereto, except to apply the funds in
accordance with the requirements of Section 10 hereof. The Pledgees may exercise
their rights with respect to property held hereunder without resort to other
security for or sources of reimbursement for the Indebtedness. In addition to
the foregoing, Pledgees shall have all of the rights, remedies and privileges of
a secured party under the Uniform Commercial Code of New York regardless of the
jurisdiction in which enforcement hereof is sought.

         27. Private Sale. Each Pledgor recognizes that the Pledgees may be
unable to effect (or to do so only after delay which would adversely affect the
value that might be realized from the Collateral) a public sale of all or part
of the Collateral by reason of certain prohibitions contained in the Securities
Act, and may be compelled to resort to one or more private sales to a restricted
group of purchasers who will be obliged to agree, among other things, to acquire
such Collateral for their own account, for investment and not with a view to the
distribution or resale thereof. Each Pledgor agrees that any such private sale
may be at prices and on terms less favorable to the seller than if sold at
public sales and that such private sales shall be deemed to have been made in a
commercially reasonable manner. Each Pledgor agrees that the Pledgees have no
obligation to delay sale of any Collateral for the period of time necessary to
permit the Issuer to register the Collateral for public sale under the
Securities Act. Any sale made pursuant to this Section 9 shall be in accordance
with federal and state securities laws.

<PAGE>

         28. Proceeds of Sale. The proceeds of any collection, recovery,
receipt, appropriation, realization or sale of the Collateral shall be applied
in accordance with the provisions of Section 8 the InterCreditor Agreement

             In the event that the proceeds of any collection, recovery,
receipt, appropriation, realization or sale are insufficient to satisfy the
Indebtedness, each Pledgor shall be jointly and severally liable for the
deficiency plus the costs and fees of any attorneys employed by Pledgees to
collect such deficiency.

         29. Waiver of Marshaling. Each Pledgor hereby waives any right to
compel any marshaling of any of the Collateral.

         30. No Waiver. Any and all of the Pledgees's rights with respect to the
Liens granted under this Agreement shall continue unimpaired, and Pledgor shall
be and remain obligated in accordance with the terms hereof, notwithstanding (a)
the bankruptcy, insolvency or reorganization of any Pledgor, (b) the release or
substitution of any item of the Collateral at any time, or of any rights or
interests therein, or (c) any delay, extension of time, renewal, compromise or
other indulgence granted by the Pledgees in reference to any of the
Indebtedness. Each Pledgor hereby waives all notice of any such delay,
extension, release, substitution, renewal, compromise or other indulgence, and
hereby consents to be bound hereby as fully and effectively as if such Pledgor
had expressly agreed thereto in advance. No delay or extension of time by the
Pledgees in exercising any power of sale, option or other right or remedy
hereunder, and no failure by the Pledgees to give notice or make demand, shall
constitute a waiver thereof, or limit, impair or prejudice the Pledgees' right
to take any action against any Pledgor or to exercise any other power of sale,
option or any other right or remedy.

         31. Expenses. The Collateral shall secure, and each Pledgor shall pay
to Pledgees on demand, from time to time, all reasonable costs and expenses,
(including but not limited to, reasonable attorneys' fees and costs, taxes, and
all transfer, recording, filing and other charges) of, or incidental to, the
custody, care, transfer, administration of the Collateral or any other
collateral, or in any way relating to the enforcement, protection or
preservation of the rights or remedies of the Pledgees under this Agreement or
with respect to any of the Indebtedness.

         32. The Pledgees Appointed Attorney-In-Fact and Performance by the
Pledgees. Upon the occurrence of an Event of Default, each Pledgor hereby
irrevocably constitutes and appoints the designated representative of the
Pledgees as such Pledgor's true and lawful attorney-in-fact, with full power of
substitution, to execute, acknowledge and deliver any instruments and to do in
such Pledgor's name, place and stead, all such acts, things and deeds for and on
behalf of and in the name of such Pledgor, which such Pledgor could or might do
or which the Pledgees may deem necessary, desirable or convenient to accomplish
the purposes of this Agreement, including, without limitation, to execute such
instruments of assignment or transfer or orders and to register, convey or
otherwise transfer title to the Collateral into the Pledgees's name. Each
Pledgor hereby ratifies and confirms all that said attorney-in-fact may so do
and hereby declares this power of attorney to be coupled with an interest and
irrevocable. If any Pledgor fails to perform any agreement herein contained, the
Pledgees may itself perform or cause performance thereof, and any costs and
expenses of the Pledgees incurred in connection therewith shall be paid by the
Pledgors as provided in Section 10 hereof.

<PAGE>

         33. Waivers.
         EACH PARTY HERETO HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF
ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT OR
ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION
HEREWITH, OR (B) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE
DEALINGS OF THE PARTIES HERETO OR ANY OTHER AGREEMENT EXECUTED OR DELIVERED BY
THEM IN CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN
EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN
CONTRACT OR TORT OR OTHERWISE.

         34. Recapture. Notwithstanding anything to the contrary in this
Agreement, if the Pledgees receive any payment or payments on account of the
Indebtedness, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to a trustee, receiver, or any other party under the
United States Bankruptcy Code, as amended, or any other federal or state
bankruptcy, reorganization, moratorium or insolvency law relating to or
affecting the enforcement of creditors' rights generally, common law or
equitable doctrine, then to the extent of any sum not finally retained by the
Pledgees, each Pledgor's obligations to the Pledgees shall be reinstated and
this Agreement shall remain in full force and effect (or be reinstated) until
payment shall have been made to Pledgees, which payment shall be due on demand.

         35. Captions. All captions in this Agreement are included herein for
convenience of reference only and shall not constitute part of this Agreement
for any other purpose.

         36. Miscellaneous.

             (a) Notwithstanding anything to the contrary contained in this
Agreement, the terms and conditions of this 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 Agreement are in contravention of

Pledgor and Laurus.

<PAGE>

             (b) No waiver of any term or condition of this Agreement, whether
by delay, omission or otherwise, shall be effective unless in writing and signed
by the party sought to be charged, and then such waiver shall be effective only

             (c) In the event that any provision of this Agreement or the
application thereof to any Pledgor or any circumstance in any jurisdiction
governing this Agreement shall, to any extent, be invalid or unenforceable under
any applicable statute, regulation, or rule of law, such provision shall be
deemed inoperative to the extent that it may conflict therewith and shall be
deemed modified to conform to such statute, regulation or rule of law, and the
remainder of this Agreement and the application of any such invalid or
unenforceable provision to parties, jurisdictions, or circumstances other than

thereby, nor shall same affect the validity or enforceability of any other
provision of this Agreement.

             (g) EXCEPT AS SET FORTH BELOW IN THIS SECTION 18(g), ANY AND ALL
DISPUTES, CONTROVERSIES AND CLAIMS THAT ANY PLEDGOR MAY ASSERT AGAINST THE
PLEDGEES ARISING OUT OF OR RELATING TO THIS 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 THE PLEDGEES AND THE COMPANY (COLLECTIVELY, THE "ARBITRATORS") IN
ACCORDANCE WITH AND PURSUANT TO THE THEN EXISTING COMMERCIAL ARBITRATION RULES

ARBITRATION. THE ARBITRATORS MAY NOT CHANGE, MODIFY OR ALTER ANY EXPRESS
CONDITION, TERM OR PROVISION OF THIS AGREEMENT OR OF ANY RELATED AGREEMENT NOR
SHALL THEY HAVE THE POWER TO RENDER ANY AWARD AGAINST THE PLEDGEES THAT WOULD
HAVE SUCH EFFECT. EACH ARBITRATION AWARD SHALL BE FINAL AND BINDING UPON THE

UNDER SECTION 18(e) HEREOF. NOTWITHSTANDING THE FOREGOING, NO PROVISIONS OF THIS
SECTION 18(g) NOR ANY OTHER PROVISION CONTAINED IN THIS AGREEMENT OR IN ANY
OTHER DOCUMENT SHALL LIMIT IN ANY MANNER WHATSOEVER THE PLEDGEES' RIGHT TO
COMMENCE AN ACTION AGAINST OR IN CONNECTION WITH ANY PLEDGOR OR ANY OF THEIR
RESPECTIVE PROPERTIES IN ANY COURT OF COMPETENT JURISDICTION OR OTHERWISE
UTILIZE JUDICIAL PROCESS IN CONNECTION WITH OR ARISING OUT OF THE PLEDGEES'

                                    GUARANTY

New York, New York                                                April __, 2005

FOR VALUE RECEIVED, and in consideration of note purchases from, loans made or
to be made or credit otherwise extended or to be extended by Sands Brothers
Venture Capital LLC, Sands Brothers Venture Capital II LLC, Sands Brothers
Venture Capital III LLC and Sands Brothers Venture Capital IV LLC (collectively,
the "Noteholders") to or for the account of Epixtar Corp., a Florida corporation
("EPXR"), and/or Voxx Corporation, a Florida corporation ("Voxx") (EPXR and
Voxx, together with each applicable subsidiary of EPXR, collectively, the
"Debtor"), from time to time and at any time and for other good and valuable
consideration and to induce Noteholders, in its discretion, to purchase such
notes, make such loans or extensions of credit and to make or grant such
renewals, extensions, releases of collateral or relinquishments of legal rights
as Noteholders may deem advisable, each of the undersigned (and each of them if
more than one, the liability under this Guaranty being joint and several)
(jointly and severally referred to as "Guarantors " or "the undersigned")
unconditionally guaranties to Noteholders, its successors, endorsees and assigns
the prompt payment when due (whether by acceleration or otherwise) of all
present and future obligations and liabilities of any and all kinds of Debtor to
Noteholders and of all instruments of any nature evidencing or relating to any
such obligations and liabilities upon which Debtor or one or more parties and
Debtor is or may become liable to Noteholders, whether incurred by Debtor as
maker, endorser, drawer, acceptor, guarantors , accommodation party or
otherwise, and whether due or to become due, secured or unsecured, absolute or
contingent, joint or several, and however or whenever acquired by Noteholders,
whether arising under, out of, or in connection with (i) that certain Securities
Purchase Agreement dated as of the date hereof by and between the Debtor and
Noteholders (the "Securities Purchase Agreement") and/or (ii) each Related
Agreement referred to in the Securities Purchase Agreement (the Securities
Purchase Agreement and each Related Agreement, as each may be amended, modified,
restated or supplemented from time to time, are collectively referred to herein
as the "Documents"), or any documents, instruments or agreements relating to or
executed in connection with the Documents or any documents, instruments or
agreements referred to therein or otherwise, or any other indebtedness,
obligations or liabilities of the Debtor to Noteholders, whether now existing or
hereafter arising, direct or indirect, liquidated or unliquidated, absolute or
contingent, due or not due and whether under, pursuant to or evidenced by a
note, agreement, guaranty, instrument or otherwise (all of which are herein
collectively referred to as the "Obligations"), and irrespective of the
genuineness, validity, regularity or enforceability of such Obligations, or of
any instrument evidencing any of the Obligations or of any collateral therefor
or of the existence or extent of such collateral, and irrespective of the
allowability, allowance or disallowance of any or all of the Obligations in any
case commenced by or against Debtor under Title 11, United States Code,
including, without limitation, obligations or indebtedness of Debtor for
post-petition interest, fees, costs and charges that would have accrued or been
added to the Obligations but for the commencement of such case, irrespective of
the allowability, allowance or disallowance of such post-petition interest,
fees, costs and charges; provided that, notwithstanding the foregoing, the
"Obligations" shall not include any principal amount of indebtedness in excess
of an aggregate amount of $1,500,000 and the rate of interest and fees related
to the Obligations shall not exceed the rate of interest and fees provided for
in the Documents (as in effect on the date hereof). Terms not otherwise defined
herein shall have the meaning assigned such terms in the Securities Purchase
Agreement. In furtherance of the foregoing, the undersigned hereby agrees as
follows:
<PAGE>

     154. No Impairment. Noteholders may at any time and from time to time,
either before or after the maturity thereof, without notice to or further
consent of the undersigned, extend the time of payment of, exchange or surrender
any collateral for, renew or extend any of the Obligations or increase or
decrease the interest rate thereon, or any other agreement with Debtor or with
any other party to or person liable on any of the Obligations, or interested
therein, for the extension, renewal, payment, compromise, discharge or release
thereof, in whole or in part, or for any modification of the terms thereof or of
any agreement between Noteholders and Debtor or any such other party or person,
or make any election of rights Noteholders may deem desirable under the United
States Bankruptcy Code, as amended, or any other federal or state bankruptcy,
reorganization, moratorium or insolvency law relating to or affecting the
enforcement of creditors' rights generally (any of the foregoing, an "Insolvency
Law") without in any way impairing or affecting this Guaranty. This instrument
shall be effective regardless of the subsequent incorporation, merger or
consolidation of Debtor, or any change in the composition, nature, personnel or
location of Debtor and shall extend to any successor entity to Debtor including
a debtor in possession or the like under any Insolvency Law.
<PAGE>

         155. Guaranty Absolute. Subject to Section 5(c), each of the
undersigned jointly and severally guarantees that the Obligations will be paid
strictly in accordance with the terms of the Documents and/or any other
document, instrument or agreement creating or evidencing the Obligations,
regardless of any law, regulation or order now or hereafter in effect in any
jurisdiction affecting any of such terms or the rights of Debtor with respect
thereto. Guarantors hereby knowingly accept the full range of risk encompassed
within a contract of "continuing guaranty" which risk includes the possibility
that Debtor will contract additional indebtedness for which Guarantors may be
liable hereunder after Debtor's financial condition or ability to pay its lawful
debts when they fall due has deteriorated, whether or not Debtor has properly
authorized incurring such additional indebtedness. The undersigned acknowledge
that (i) no oral representations, including any representations to extend credit
or provide other financial accommodations to Debtor, have been made by
Noteholders to induce the undersigned to enter into this Guaranty and (ii) any
extension of credit to the Debtor shall be governed solely by the provisions of
the Documents. The liability of each of the undersigned under this Guaranty
shall be absolute and unconditional, in accordance with its terms, and shall
remain in full force and effect without regard to, and shall not be released,
suspended, discharged, terminated or otherwise affected by, any circumstance or
occurrence whatsoever, including, without limitation: (a) any waiver,
indulgence, renewal, extension, amendment or modification of or addition,
consent or supplement to or deletion from or any other action or inaction under
or in respect of the Documents or any other instruments or agreements relating
to the Obligations or any assignment or transfer of any thereof, (b) any lack of
validity or enforceability of any Document or other documents, instruments or
agreements relating to the Obligations or any assignment or transfer of any
thereof, (c) any furnishing of any additional security to Noteholders or its
assignees or any acceptance thereof or any release of any security by
Noteholders or its assignees, (d) any limitation on any party's liability or
obligation under the Documents or any other documents, instruments or agreements
relating to the Obligations or any assignment or transfer of any thereof or any
invalidity or unenforceability, in whole or in part, of any such document,
instrument or agreement or any term thereof, (e) any bankruptcy, insolvency,
reorganization, composition, adjustment, dissolution, liquidation or other like
proceeding relating to Debtor, or any action taken with respect to this Guaranty
by any trustee or receiver, or by any court, in any such proceeding, whether or
not the undersigned shall have notice or knowledge of any of the foregoing, (f)
any exchange, release or nonperfection of any collateral, or any release, or
amendment or waiver of or consent to departure from any guaranty or security,
for all or any of the Obligations or (g) any other circumstance which might
otherwise constitute a defense available to, or a discharge of, the undersigned.
Any amounts due from the undersigned to Noteholders shall bear interest until
such amounts are paid in full at the highest rate then applicable to the
Obligations. Obligations include post-petition interest whether or not allowed
or allowable.
<PAGE>

         156. Waivers.

                  156.1 This Guaranty is a guaranty of payment and not of
collection. Noteholders shall be under no obligation to institute suit, exercise
rights or remedies or take any other action against Debtor or any other person
liable with respect to any of the Obligations or resort to any collateral
security held by it to secure any of the Obligations as a condition precedent to
the undersigned being obligated to perform as agreed herein and each of the
Guarantors hereby waives any and all rights which it may have by statute or
otherwise which would require Noteholders to do any of the foregoing. Each of
the Guarantors further consents and agrees that Noteholders shall be under no
obligation to marshal any assets in favor of Guarantors, or against or in
payment of any or all of the Obligations. The undersigned hereby waives all
suretyship defenses and any rights to interpose any defense, counterclaim or
offset of any nature and description which the undersigned may have or which may
exist between and among Noteholders, Debtor and/or the undersigned with respect
to the undersigned's obligations under this Guaranty, or which Debtor may assert
on the underlying debt, including but not limited to failure of consideration,
breach of warranty, fraud, payment (other than cash payment in full of the
Obligations), statute of frauds, bankruptcy, infancy, statute of limitations,
accord and satisfaction, and usury.

                  156.2 Each of the undersigned further waives (i) notice of the
acceptance of this Guaranty, of the making of any such loans or extensions of
credit, and of all notices and demands of any kind to which the undersigned may
be entitled, including, without limitation, notice of adverse change in Debtor's
financial condition or of any other fact which might materially increase the
risk of the undersigned and (ii) presentment to or demand of payment from anyone
whomsoever liable upon any of the Obligations, protest, notices of presentment,
non-payment or protest and notice of any sale of collateral security or any
default of any sort.

                  156.3 Notwithstanding any payment or payments made by the
undersigned hereunder, or any setoff or application of funds of the undersigned
by Noteholders, the undersigned shall not be entitled to be subrogated to any of
the rights of Noteholders against Debtor or against any collateral or guarantee
or right of offset held by Noteholders for the payment of the Obligations, nor
shall the undersigned seek or be entitled to seek any contribution or
reimbursement from Debtor in respect of payments made by the undersigned
hereunder, until all amounts owing to Noteholders by Debtor on account of the
Obligations are paid in full and Noteholders' obligation to extend credit
pursuant to the Documents have been terminated. If, notwithstanding the
foregoing, any amount shall be paid to the undersigned on account of such
subrogation rights at any time when all of the Obligations shall not have been
paid in full and Noteholders' obligation to extend credit pursuant to the
Documents shall not have been terminated, such amount shall be held by the
undersigned in trust for Noteholders, segregated from other funds of the
undersigned, and shall forthwith upon, and in any event within two (2) business
days of, receipt by the undersigned, be turned over to Noteholders in the exact
form received by the undersigned (duly endorsed by the undersigned to
Noteholders, if required), to be applied against the Obligations, whether
matured or unmatured, in such order as Noteholders may determine, subject to the
provisions of the Documents. Any and all present and future debts and
obligations of Debtor to any of the undersigned are hereby waived and postponed
in favor of, and subordinated to the full payment and performance of, all
present and future debts and Obligations of Debtor to Noteholders.
<PAGE>

         157. Security. All sums at any time to the credit of the undersigned
and any property of the undersigned in Noteholders' possession or in the
possession of any bank, financial institution or other entity that directly or
indirectly, through one or more intermediaries, controls or is controlled by, or
is under common control with, Noteholders (each such entity, an "Affiliate")
shall be deemed held by Noteholders or such Affiliate, as the case may be, as
security for any and all of the undersigned's obligations to Noteholders and to
any Affiliate of Noteholders, no matter how or when arising and whether under
this or any other instrument, agreement or otherwise.

         158. Representations and Warranties. Each of the undersigned
respectively, hereby jointly and severally represents and warrants (all of which
representations and warranties shall survive until all Obligations are
indefeasibly satisfied in full and the Documents have been irrevocably
terminated), that:

                  158.1 Corporate Status. It is a corporation, partnership or
limited liability company, as the case may be, duly organized, validly existing

right to own its property and assets and to transact the business in which it is
engaged.

                  158.2 Authority and Execution. It has full power, authority
and legal right to execute and deliver, and to perform its obligations under,
this Guaranty and has taken all necessary corporate, partnership or limited
liability company, as the case may be, action to authorize the execution,
delivery and performance of this Guaranty.

                  158.3 Legal, Valid and Binding Character. This Guaranty
constitutes its legal, valid and binding obligation enforceable in accordance
with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other laws of general
application affecting the enforcement of creditor's rights and general
principles of equity that restrict the availability of equitable or legal
remedies.

                  158.4 Violations. The execution, delivery and performance of
this Guaranty will not violate any requirement of law applicable to it or any
contract, agreement or instrument to it is a party or by which it or any of its
property is bound or result in the creation or imposition of any mortgage, lien
or other encumbrance other than to Noteholders on any of its property or assets
pursuant to the provisions of any of the foregoing, which, in any of the
foregoing cases, could reasonably be expected to have, either individually or in
the aggregate, a Material Adverse Effect.

                  158.5 Consents or Approvals. No consent of any other person or
entity (including, without limitation, any creditor of the undersigned) and no
consent, license, permit, approval or authorization of, exemption by, notice or
report to, or registration, filing or declaration with, any governmental
authority is required in connection with the execution, delivery, performance,
validity or enforceability of this Guaranty by it, except to the extent that the
failure to obtain any of the foregoing could not reasonably be expected to have,
either individually or in the aggregate, a Material Adverse Effect.
<PAGE>

                  158.6 Litigation. No litigation, arbitration, investigation or
administrative proceeding of or before any court, arbitrator or governmental
authority, bureau or agency is currently pending or, to the best of its
knowledge, threatened (i) with respect to this Guaranty or any of the
transactions contemplated by this Guaranty or (ii) against or affecting it, or
any of its property or assets, which, in each of the foregoing cases, if
adversely determined, could reasonably be expected to have a Material Adverse
Effect.

                  158.7 Financial Benefit. It has derived or expects to derive a
financial or other advantage from each and every loan, advance or extension of
credit made under the Documents or other Obligation incurred by the Debtor to
Noteholders.

         159. Acceleration.

                  159.1 If any breach of any covenant or condition or other
event of default shall occur and be continuing under any agreement made by
Debtor or any of the undersigned to Noteholders, or either Debtor or any of the
undersigned should at any time become insolvent, or make a general assignment,
or if a proceeding in or under any Insolvency Law shall be filed or commenced
by, or in respect of, any of the undersigned, or if a notice of any lien, levy,
or assessment is filed of record with respect to any assets of any of the
undersigned by the United States of America or any department, agency, or
instrumentality thereof, or if any taxes or debts owing at any time or times
hereafter to any one of them becomes a lien or encumbrance upon any assets of
the undersigned in Noteholders' possession, or otherwise, any and all
Obligations shall for purposes hereof, at Noteholders' option, be deemed due and
payable without notice notwithstanding that any such Obligation is not then due
and payable by Debtor.

                  159.2 Each of the undersigned will promptly notify Noteholders
of any default by such undersigned in its respective performance or observance
of any term or condition of any agreement to which the undersigned is a party if
the effect of such default is to cause, or permit the holder of any obligation
under such agreement to cause, such obligation to become due prior to its stated
maturity and, if such an event occurs, Noteholders shall have the right to
accelerate such undersigned's obligations hereunder.

         160. Payments from Guarantors. Noteholders, in its sole and absolute
discretion, with or without notice to the undersigned, may apply on account of
the Obligations any payment from the undersigned or any other guarantors, or
amounts realized from any security for the Obligations, or may deposit any and
all such amounts realized in a non-interest bearing cash collateral deposit
account to be maintained as security for the Obligations.

         161. Costs. The undersigned shall pay on demand, all costs, fees and
expenses (including expenses for legal services of every kind) relating or
incidental to the enforcement or protection of the rights of Noteholders
hereunder or under any of the Obligations.
<PAGE>

         162. No Termination. This is a continuing irrevocable guaranty and
shall remain in full force and effect and be binding upon the undersigned, and
each of the undersigned's successors and assigns, until all of the Obligations
have been paid in full and Noteholders' obligation to extend credit pursuant to
the Documents has been irrevocably terminated. If any of the present or future
Obligations are guarantied by persons, partnerships or corporations in addition
to the undersigned, the death, release or discharge in whole or in part or the
bankruptcy, merger, consolidation, incorporation, liquidation or dissolution of
one or more of them shall not discharge or affect the liabilities of any
undersigned under this Guaranty.

         163. Recapture. Anything in this Guaranty to the contrary
notwithstanding, if Noteholders receives any payment or payments on account of
the liabilities guaranteed hereby, which payment or payments or any part thereof
are subsequently invalidated, declared to be fraudulent or preferential, set
aside and/or required to be repaid to a trustee, receiver, or any other party
under any Insolvency Law, common law or equitable doctrine, then to the extent
of any sum not finally retained by Noteholders, the undersigned's obligations to
Noteholders shall be reinstated and this Guaranty shall remain in full force and
effect (or be reinstated) until payment shall have been made to Noteholders,
which payment shall be due on demand.

         164. Books and Records. The books and records of Noteholders showing
the account between Noteholders and Debtor shall be admissible in evidence in
any action or proceeding, shall be binding upon the undersigned for the purpose
of establishing the items therein set forth and shall constitute prima facie
proof thereof.

         165. No Waiver. No failure on the part of Noteholders to exercise, and
no delay in exercising, any right, remedy or power hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise by Noteholders of any
right, remedy or power hereunder preclude any other or future exercise of any
other legal right, remedy or power. Each and every right, remedy and power
hereby granted to Noteholders or allowed it by law or other agreement shall be
cumulative and not exclusive of any other, and may be exercised by Noteholders
at any time and from time to time.

         166. Waiver of Jury Trial. EACH OF THE UNDERSIGNED DOES HEREBY
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT TO TRIAL BY JURY IN ANY
ACTION OR PROCEEDING BASED ON OR WITH RESPECT TO THIS GUARANTY OR ANY OF THE
TRANSACTIONS CONTEMPLATED HEREBY OR RELATING OR INCIDENTAL HERETO. THE
UNDERSIGNED DOES HEREBY CERTIFY THAT NO REPRESENTATIVE OR AGENT OF NOTEHOLDERS
HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT NOTEHOLDERS WOULD NOT, IN THE
EVENT OF LITIGATION, SEEK TO ENFORCE THIS WAIVER OF RIGHT TO JURY TRIAL
PROVISION.

         167. Governing Law; Jurisdiction; Amendments. THIS INSTRUMENT CANNOT BE
CHANGED OR TERMINATED ORALLY, AND SHALL BE GOVERNED, CONSTRUED AND INTERPRETED
AS TO VALIDITY, ENFORCEMENT AND IN ALL OTHER RESPECTS IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK WITHOUT HAVING EFFECT TO PRINCIPLES OF CONFLICTS
OF LAWS. EXCEPT AS SET FORTH BELOW IN THIS SECTION 14, ANY AND ALL DISPUTES,
CONTROVERSIES AND CLAIMS THAT ANY GUARANTOR MAY ASSERT AGAINST NOTEHOLDERS
ARISING OUT OF OR RELATING TO THIS GUARANTY 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
NOTEHOLDERS AND THE DEBTOR (COLLECTIVELY, THE "ARBITRATORS") IN ACCORDANCE WITH
AND PURSUANT TO THE THEN EXISTING COMMERCIAL ARBITRATION RULES OF THE AMERICAN
ARBITRATION ASSOCIATION. EACH GUARANTOR 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 GUARANTY OR OF ANY OTHER DOCUMENT NOR SHALL THEY HAVE THE
POWER TO RENDER ANY AWARD AGAINST NOTEHOLDERS 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 17 HEREOF.
NOTWITHSTANDING THE FOREGOING, THE PROVISIONS OF THIS SECTION 14 NOR ANY OTHER
PROVISION CONTAINED IN THIS GUARANTY OR IN ANY OTHER DOCUMENT SHALL LIMIT IN ANY
