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

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

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

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

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

its corporate purposes as directed by the Voxx Assignors;

<PAGE>

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

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

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

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

         seizure or attachment thereof or thereon except to the extent:

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

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

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

                  26.3     any proceedings under any bankruptcy or insolvency
law shall be commenced by or against any Assignor and if commenced against any
Assignor shall not be dismissed within forty-five (45) days;

defined in any Document.

<PAGE>

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

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

<PAGE>

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

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

<PAGE>

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

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

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

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

         prepare and file with the Commission a Registration Statement covering
         the Registrable Securities for an offering to be made on a continuous
         basis pursuant to Rule 415. The Registration Statement shall be on Form
         S-1 or SB-2 (except if the Company is not then eligible to register for
         resale the Registrable Securities on Form S-1 or SB-2, in which case
         such registration shall be on another appropriate form in accordance
         herewith). The Company shall cause the Registration Statement to become
         effective and remain effective as provided herein. The Company shall
         use its reasonable commercial efforts to cause the Registration
         Statement to be declared effective under the Securities Act as promptly
         as possible after the filing thereof, but in any event no later than
         the Effectiveness Date. The Company shall use its reasonable commercial
         efforts to keep the Registration Statement continuously effective under
         the Securities Act until the date which is the earlier date of when (i)
         all Registrable Securities have been sold or (ii) all Registrable
         Securities may be sold immediately without registration under the
         Securities Act and without volume restrictions pursuant to Rule 144(k),
         as determined by the counsel to the Company pursuant to a written
         opinion letter to such effect, addressed and acceptable to the
         Company's transfer agent and the affected Holders (the "Effectiveness
         Period").

                  (b)34.2 If: (i) the Registration Statement is not filed on or
         prior to the Filing Date; (ii) the Registration Statement is not
         declared effective by the Commission by the Effectiveness Date; (iii)
         after the Registration Statement is filed with and declared effective
         by the Commission, the Registration Statement ceases to be effective
         (by suspension or otherwise) as to all Registrable Securities to which
         it is required to relate at any time prior to the expiration of the
         Effectiveness Period (without being succeeded immediately by an
         additional registration statement filed and declared effective) for a
         period of time which shall exceed 30 days in the aggregate per year or
         more than 20 consecutive calendar days (defined as a period of 365 days
         commencing on the date the Registration Statement is declared
         effective); or (iv) the Common Stock is not listed or quoted, or is
         suspended from trading on any Trading Market for a period of three (3)
         consecutive Trading Days (provided the Company shall not have been able
         to cure such trading suspension within 30 days of the notice thereof or
         list the Common Stock on another Trading Market); (any such failure or
         breach being referred to as an "Event," and for purposes of clause (i)
         or (ii) the date on which such Event occurs, or for purposes of clause
         (iii) the date which such 30 day or 20 consecutive day period (as the
         case may be) is exceeded, or for purposes of clause (iv) the date on
         which such three (3) Trading Day period is exceeded, being referred to
         as "Event Date"), then until the applicable Event is cured, the Company
         shall pay to each Holder an amount in cash, as liquidated damages and
         not as a penalty, equal to 2.0% for each thirty (30) day period
         (prorated for partial periods) on a daily basis of the original
         principal amount of the Note. While such Event continues, such
         liquidated damages shall be paid not less often than each thirty (30)
         days. Any unpaid liquidated damages as of the date when an Event has
         been cured by the Company shall be paid within three (3) days following
         the date on which such Event has been cured by the Company.
<PAGE>

                  (c) Within three business days of the Effectiveness Date, the
         Company shall cause its counsel to issue a blanket opinion in the form
         attached hereto as Exhibit A, to the transfer agent stating that the
         shares are subject to an effective registration statement and can be
         reissued free of restrictive legend upon notice of a sale by the
         Purchaser and confirmation by the Purchaser that it has complied with
         the prospectus delivery requirements, provided that the Company has not
         advised the transfer agent orally or in writing that the opinion has
         been withdrawn. Copies of the blanket opinion required by this Section
         2(c) shall be delivered to the Purchaser within the time frame set
         forth above.

         3.35. Registration Procedures. If and whenever the Company is required
by the provisions hereof to effect the registration of any Registrable
Securities under the Securities Act, the Company will, as expeditiously as
possible:

                  (a)35.1 prepare and file with the Commission the Registration
         Statement with respect to such Registrable Securities, respond as
         promptly as possible to any comments received from the Commission, and
         use its best efforts to cause the Registration Statement to become and
         remain effective for the Effectiveness Period with respect thereto, and
         promptly provide to the Purchaser copies of all filings and Commission
         letters of comment relating thereto;

                  (b)35.2 prepare and file with the Commission such amendments
         and supplements to the Registration Statement and the Prospectus used
         in connection therewith as may be necessary to comply with the
         provisions of the Securities Act with respect to the disposition of all
         Registrable Securities covered by the Registration Statement and to
         keep such Registration Statement effective until the expiration of the
         Effectiveness Period;
<PAGE>

                  (c)35.3 furnish to the Purchaser such number of copies of the
         Registration Statement and the Prospectus included therein (including
         each preliminary Prospectus) as the Purchaser reasonably may request to
         facilitate the public sale or disposition of the Registrable Securities
         covered by the Registration Statement;

                  (d)35.4 use its commercially reasonable efforts to register or
         qualify the Purchaser's Registrable Securities covered by the
         Registration Statement under the securities or "blue sky" laws of such
         jurisdictions within the United States as the Purchaser may reasonably
         request, provided, however, that the Company shall not for any such
         purpose be required to qualify generally to transact business as a
         foreign corporation in any jurisdiction where it is not so qualified or
         to consent to general service of process in any such jurisdiction;

                  (e)35.5 list the Registrable Securities covered by the
         Registration Statement with any securities exchange on which the Common
         Stock of the Company is then listed;

                  (f)35.6 immediately notify the Purchaser at any time when a
         Prospectus relating thereto is required to be delivered under the
         Securities Act, of the happening of any event of which the Company has
         knowledge as a result of which the Prospectus contained in such
         Registration Statement, as then in effect, includes an untrue statement
         of a material fact or omits to state a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading in light of the circumstances then existing; and

                  (g)35.7 make available for inspection by the Purchaser and any
         attorney, accountant or other agent retained by the Purchaser, all
         publicly available, non-confidential financial and other records,
         pertinent corporate documents and properties of the Company, and cause
         the Company's officers, directors and employees to supply all publicly
         available, non-confidential information reasonably requested by the
         attorney, accountant or agent of the Purchaser.

         4.36. Registration Expenses. All expenses relating to the Company's
compliance with Sections 2 and 3 hereof, including, without limitation, all
registration and filing fees, printing expenses, fees and disbursements of
counsel and independent public accountants for the Company, fees and expenses
(including reasonable counsel fees) incurred in connection with complying with
state securities or "blue sky" laws, fees of the NASD, transfer taxes, fees of
transfer agents and registrars, fees of, and disbursements incurred by, one
counsel for the Holders (to the extent such counsel is required due to Company's
failure to meet any of its obligations hereunder), are called "Registration
Expenses". All selling commissions applicable to the sale of Registrable
Securities, including any fees and disbursements of any special counsel to the
Holders beyond those included in Registration Expenses, are called "Selling
Expenses." The Company shall only be responsible for all Registration Expenses.

         5.37. Indemnification.

                  (a)37.1 In the event of a registration of any Registrable
         Securities under the Securities Act pursuant to this Agreement, the
         Company will indemnify and hold harmless the Purchaser, and its
         officers, directors and each other person, if any, who controls the
         Purchaser within the meaning of the Securities Act, against any losses,
         claims, damages or liabilities, joint or several, to which the
         Purchaser, or such persons may become subject under the Securities Act
         or otherwise, insofar as such losses, claims, damages or liabilities
         (or actions in respect thereof) arise out of or are based upon any
         untrue statement or alleged untrue statement of any material fact
         contained in any Registration Statement under which such Registrable
         Securities were registered under the Securities Act pursuant to this
         Agreement, any preliminary Prospectus or final Prospectus contained
         therein, or any amendment or supplement thereof, or arise out of or are
         based upon the omission or alleged omission to state therein a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading, and will reimburse the Purchaser, and each such
         person for any reasonable legal or other expenses incurred by them in
         connection with investigating or defending any such loss, claim,
         damage, liability or action; provided, however, that the Company will
         not be liable in any such case if and to the extent that any such loss,
         claim, damage or liability arises out of or is based upon an untrue
         statement or alleged untrue statement or omission or alleged omission
         so made in conformity with information furnished by or on behalf of the
         Purchaser or any such person in writing specifically for use in any
         such document.

                  (b)37.2 In the event of a registration of the Registrable
         Securities under the Securities Act pursuant to this Agreement, the
         Purchaser will indemnify and hold harmless the Company, and its
         officers, directors and each other person, if any, who controls the
         Company within the meaning of the Securities Act, against all losses,
         claims, damages or liabilities, joint or several, to which the Company
         or such persons may become subject under the Securities Act or
         otherwise, insofar as such losses, claims, damages or liabilities (or
         actions in respect thereof) arise out of or are based upon any untrue
         statement or alleged untrue statement of any material fact which was
         furnished in writing by the Purchaser to the Company expressly for use
         in (and such information is contained in) the Registration Statement
         under which such Registrable Securities were registered under the
         Securities Act pursuant to this Agreement, any preliminary Prospectus
         or final Prospectus contained therein, or any amendment or supplement
         thereof, or arise out of or are based upon the omission or alleged
         omission to state therein a material fact required to be stated therein
         or necessary to make the statements therein not misleading, and will
         reimburse the Company and each such person for any reasonable legal or
         other expenses incurred by them in connection with investigating or
         defending any such loss, claim, damage, liability or action, provided,
         however, that the Purchaser will be liable in any such case if and only
         to the extent that any such loss, claim, damage or liability arises out
         of or is based upon an untrue statement or alleged untrue statement or
         omission or alleged omission so made in conformity with information
         furnished in writing to the Company by or on behalf of the Purchaser
         specifically for use in any such document. Notwithstanding the
         provisions of this paragraph, the Purchaser shall not be required to
         indemnify any person or entity in excess of the amount of the aggregate
         net proceeds received by the Purchaser in respect of Registrable
         Securities in connection with any such registration under the
         Securities Act.
<PAGE>

                  (c)37.3 Promptly after receipt by a party entitled to claim
         indemnification hereunder (an "Indemnified Party") of notice of the
         commencement of any action, such Indemnified Party shall, if a claim
         for indemnification in respect thereof is to be made against a party
         hereto obligated to indemnify such Indemnified Party (an "Indemnifying
         Party"), notify the Indemnifying Party in writing thereof, but the
         omission so to notify the Indemnifying Party shall not relieve it from
         any liability which it may have to such Indemnified Party other than
         under this Section 5(c) and shall only relieve it from any liability
         which it may have to such Indemnified Party under this Section 5(c) if
         and to the extent the Indemnifying Party is prejudiced by such
         omission. In case any such action shall be brought against any
         Indemnified Party and it shall notify the Indemnifying Party of the
         commencement thereof, the Indemnifying Party shall be entitled to
         participate in and, to the extent it shall wish, to assume and
         undertake the defense thereof with counsel satisfactory to such
         Indemnified Party, and, after notice from the Indemnifying Party to
         such Indemnified Party of its election so to assume and undertake the
         defense thereof, the Indemnifying Party shall not be liable to such
         Indemnified Party under this Section 5(c) for any legal expenses
         subsequently incurred by such Indemnified Party in connection with the
         defense thereof; if the Indemnified Party retains its own counsel, then
         the Indemnified Party shall pay all fees, costs and expenses of such
         counsel, provided, however, that, if the defendants in any such action
         include both the indemnified party and the Indemnifying Party and the
         Indemnified Party shall have reasonably concluded that there may be
         reasonable defenses available to it which are different from or
         additional to those available to the Indemnifying Party or if the
         interests of the Indemnified Party reasonably may be deemed to conflict
         with the interests of the Indemnifying Party, the Indemnified Party
         shall have the right to select one separate counsel and to assume such
         legal defenses and otherwise to participate in the defense of such
         action, with the reasonable expenses and fees of such separate counsel
         and other expenses related to such participation to be reimbursed by
         the Indemnifying Party as incurred.

                  (d)37.4 In order to provide for just and equitable
         contribution in the event of joint liability under the Securities Act
         in any case in which either (i) the Purchaser, or any officer, director
         or controlling person of the Purchaser, makes a claim for
         indemnification pursuant to this Section 5 but it is judicially
         determined (by the entry of a final judgment or decree by a court of
         competent jurisdiction and the expiration of time to appeal or the
         denial of the last right of appeal) that such indemnification may not
         be enforced in such case notwithstanding the fact that this Section 5
         provides for indemnification in such case, or (ii) contribution under
         the Securities Act may be required on the part of the Purchaser or such
         officer, director or controlling person of the Purchaser in
         circumstances for which indemnification is provided under this Section
         5; then, and in each such case, the Company and the Purchaser will
         contribute to the aggregate losses, claims, damages or liabilities to
         which they may be subject (after contribution from others) in such
         proportion so that the Purchaser is responsible only for the portion
         represented by the percentage that the public offering price of its
         securities offered by the Registration Statement bears to the public
         offering price of all securities offered by such Registration
         Statement, provided, however, that, in any such case, (A) the Purchaser
         will not be required to contribute any amount in excess of the public
         offering price of all such securities offered by it pursuant to such
         Registration Statement; and (B) no person or entity guilty of
         fraudulent misrepresentation (within the meaning of Section 10(f) of
         the Securities Act) will be entitled to contribution from any person or
         entity who was not guilty of such fraudulent misrepresentation.

         6.38. Representations, Warranties and Covenants.

                  (a)38.1 The Common Stock of the Company is registered pursuant
         to Section 12(b) or 12(g) of the Exchange Act and, except with respect
         to certain matters which the Company has disclosed to the Purchaser on
         Schedule 4.21 to the Securities Purchase Agreement, the Company has
         timely filed all proxy statements, reports, schedules, forms,
         statements and other documents required to be filed by it under the
         Exchange Act. The Company has filed (i) its Annual Report on Form 10-K
         for its fiscal year ended December 31, 2004 and (ii) its Quarterly
         Report on Form 10-Q for its fiscal quarter ended September 30, 2004,
         and (iii) the Form 8-K filings which it has made during the fiscal year
         2005 to date (collectively, the "SEC Reports"). 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. The financial
         statements of the Company included in the SEC Reports comply as to form
         in all material respects with applicable accounting requirements and
         the published rules and regulations of the Commission or other
         applicable rules and regulations with respect thereto. Such financial
         statements have been prepared in accordance with generally accepted
         accounting principles ("GAAP") applied on a consistent basis during the
         periods involved (except (i) as may be otherwise indicated in such
         financial statements or the notes thereto or (ii) in the case of
         unaudited interim statements, to the extent they may not include
         footnotes or may be condensed) and fairly present in all material
         respects the financial condition, the results of operations and the
         cash flows of the Company and its subsidiaries, on a consolidated
         basis, as of, and for, the periods presented in each such SEC Report.

                  (b)38.2 The Common Stock is traded on the NASD OTCBB and
         satisfies all requirements for the continuation of such trading. The
         Company has not received any notice that its Common Stock will not be
         eligible to be traded on the NASD OTCBB (except for prior notices which
         have been fully remedied) or that the Common Stock does not meet all
         requirements for the continuation of such trading.
<PAGE>

                  (c)38.3 Neither the Company, nor any of its affiliates, nor
         any person acting on its or their behalf, has directly or indirectly
         made any offers or sales of any security or solicited any offers to buy
         any security under circumstances that would cause the offering of the
         Securities pursuant to the Securities Purchase Agreement to be
         integrated with prior offerings by the Company for purposes of the
         Securities Act which would prevent the Company from selling the Common
         Stock pursuant to Rule 506 under the Securities Act, or any applicable
         exchange-related stockholder approval provisions, nor will the Company
         or any of its affiliates or subsidiaries take any action or steps that
         would cause the offering of the Securities to be integrated with other
         offerings.

                  (d)38.4 The Note and the shares of Common Stock which the
         Purchaser may acquire pursuant to the Note are all restricted
         securities under the Securities Act as of the date of this Agreement.
         The Company will not issue any stop transfer order or other order
         impeding the sale and delivery of any of the Registrable Securities at
         such time as such Registrable Securities are registered for public sale
         or an exemption from registration is available, except as required by
         federal or state securities laws or as otherwise permitted by this
         Agreement, the Purchase Agreement or any Related Agreement.

                  (e)38.5 The Company understands the nature of the Registrable
         Securities issuable upon the conversion of the Note and recognizes that
         the issuance of such Registrable Securities may have a potential
         dilutive effect. The Company specifically acknowledges that its
         obligation to issue the Registrable Securities is binding upon the
         Company and enforceable regardless of the dilution such issuance may
         have on the ownership interests of other shareholders of the Company.

                  (f)38.6 Except for agreements made in the ordinary course of
         business, there is no agreement that has not been filed with the
         Commission as an exhibit to a registration statement or to a form
         required to be filed by the Company under the Exchange Act, the breach
         of which could reasonably be expected to have a material and adverse
         effect on the Company and its subsidiaries, or would prohibit or
         otherwise interfere with the ability of the Company to enter into and
         perform any of its obligations under this Agreement in any material
         respect.

                  (g)38.7 The Company will at all times have authorized and
         reserved a sufficient number of shares of Common Stock for the full
         conversion of the Note.

         7.39. Miscellaneous.

                  (a)39.1 Remedies. In the event of a breach by the Company or
         by a Holder, of any of their respective obligations under this
         Agreement, each Holder or the Company, as the case may be, in addition
         to being entitled to exercise all rights granted by law and under this
         Agreement, including recovery of damages, will be entitled to specific
         performance of its rights under this Agreement.
<PAGE>

                  (b)39.2 No Piggyback on Registrations. Except as and to the
         extent specified in Schedule 7(b) hereto, neither the Company nor any
         of its security holders (other than the Holders in such capacity
         pursuant hereto) may include securities of the Company in any
         Registration Statement other than the Registrable Securities, and the
         Company shall not after the date hereof enter into any agreement
         providing any such right for inclusion of shares in the Registration
         Statement to any of its security holders. Except as and to the extent
         specified in Schedule 7(b) hereto, the Company has not previously
         entered into any agreement granting any registration rights with
         respect to any of its securities to any Person that have not been fully
         satisfied.

                  (c)39.3 Compliance. Each Holder covenants and agrees that it
         will comply with the prospectus delivery requirements of the Securities
         Act as applicable to it in connection with sales of Registrable
         Securities pursuant to the Registration Statement.

                  (d)39.4 Discontinued Disposition. Each Holder agrees by its
         acquisition of such Registrable Securities that, upon receipt of a
         notice from the Company of the occurrence of a Discontinuation Event
         (as defined below), such Holder will forthwith discontinue disposition
         of such Registrable Securities under the applicable Registration
         Statement until such Holder's receipt of the copies of the supplemented
         Prospectus and/or amended Registration Statement or until it is advised
         in writing (the "Advice") by the Company that the use of the applicable
         Prospectus may be resumed, and, in either case, has received copies of
         any additional or supplemental filings that are incorporated or deemed
         to be incorporated by reference in such Prospectus or Registration
         Statement. The Company may provide appropriate stop orders to enforce
         the provisions of this paragraph. For purposes of this Section 7(d), a
         "Discontinuation Event" shall mean (i) when the Commission notifies the
         Company whether there will be a "review" of such Registration Statement
         and whenever the Commission comments in writing on such Registration
         Statement (the Company shall provide true and complete copies thereof
         and all written responses thereto to each of the Holders); (ii) any
         request by the Commission or any other Federal or state governmental
         authority for amendments or supplements to such Registration Statement
         or Prospectus or for additional information; (iii) the issuance by the
         Commission of any stop order suspending the effectiveness of such
         Registration Statement covering any or all of the Registrable
         Securities or the initiation of any Proceedings for that purpose; (iv)
         the receipt by the Company of any notification with respect to the
         suspension of the qualification or exemption from qualification of any
         of the Registrable Securities for sale in any jurisdiction, or the
         initiation or threatening of any Proceeding for such purpose; and/or
         (v) the occurrence of any event or passage of time that makes the
         financial statements included in such Registration Statement ineligible
         for inclusion therein or any statement made in such Registration
         Statement or Prospectus or any document incorporated or deemed to be
         incorporated therein by reference untrue in any material respect or
         that requires any revisions to such Registration Statement, Prospectus
         or other documents so that, in the case of such Registration Statement
         or Prospectus, as the case may be, it will not contain any untrue
         statement of a material fact or omit to state any 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.
<PAGE>

                  (e)39.5 Piggy-Back Registrations. If at any time during the
         Effectiveness Period there is not an effective Registration Statement
         covering all of the Registrable Securities and the Company shall
         determine to prepare and file with the Commission a registration
         statement relating to an offering for its own account or the account of
         others under the Securities Act of any of its equity securities, other
         than on Form S-4 or Form S-8 (each as promulgated under the Securities
         Act) or their then equivalents relating to equity securities to be
         issued solely in connection with any acquisition of any entity or
         business or equity securities issuable in connection with stock option
         or other employee benefit plans, then the Company shall send to each
         Holder written notice of such determination and, if within fifteen days
         after receipt of such notice, any such Holder shall so request in
         writing, the Company shall include in such registration statement all
         or any part of such Registrable Securities such holder requests to be
         registered to the extent the Company may do so without violating
         registration rights of others which exist as of the date of this
         Agreement, subject to customary underwriter cutbacks applicable to all
         holders of registration rights and subject to obtaining any required
         the consent of any selling stockholder(s) to such inclusion under such
         registration statement.

                  (f)39.6 Amendments and Waivers. The provisions of this
         Agreement, including the provisions of this sentence, may not be
         amended, modified or supplemented, and waivers or consents to
         departures from the provisions hereof may not be given, unless the same
         shall be in writing and signed by the Company and the Holders of the
         then outstanding Registrable Securities. Notwithstanding the foregoing,
         a waiver or consent to depart from the provisions hereof with respect
         to a matter that relates exclusively to the rights of certain Holders
         and that does not directly or indirectly affect the rights of other
         Holders may be given by Holders of at least a majority of the
         Registrable Securities to which such waiver or consent relates;
         provided, however, that the provisions of this sentence may not be
         amended, modified, or supplemented except in accordance with the
         provisions of the immediately preceding sentence.

                  (g)39.7 Notices. Any notice or request hereunder may be given
         to the Company or the Purchaser at the respective addresses set forth
         below or as may hereafter be specified in a notice designated as a
         change of address under this Section 7(g). Any notice or request
         hereunder shall be given by registered or certified mail, return
         receipt requested, hand delivery, overnight mail, Federal Express or
         other national overnight next day carrier (collectively, "Courier") or
         telecopy (confirmed by mail). Notices and requests shall be, in the
         case of those by hand delivery, deemed to have been given when
         delivered to any party to whom it is addressed, in the case of those by
         mail or overnight mail, deemed to have been given three (3) business
         days after the date when deposited in the mail or with the overnight
         mail carrier, in the case of a Courier, the next business day following
         timely delivery of the package with the Courier, and, in the case of a
         telecopy, when confirmed. The address for such notices and
         communications shall be as follows:

                  (j)39.10 Governing Law. All questions concerning the
         construction, validity, enforcement and interpretation of this
         Agreement shall be governed by and construed and enforced in accordance
         with the internal laws of the State of New York, without regard to the
         principles of conflicts of law thereof. Except as set forth below in
         this Section 7(j), any and all disputes, controversies and claims that
         the Company or any of its Subsidiaries may assert against the Purchaser
         arising out of or relating to this Agreement, the Securities 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 Purchaser and the Company (collectively, the "Arbitrators") in
         accordance with and pursuant to the then existing commercial
         arbitration rules of the American Arbitration Association. The Company
         (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 Agreement, the Securities Purchase Agreement or of
         any other Related Agreement nor shall they have the power to render any
         award against the Purchaser 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 7(g) hereof. Notwithstanding the foregoing,
         the provisions of this Section 7(j) nor any other provision contained
         in this Agreement, the Securities Purchase Agreement or in any Related
         Agreement shall limit in any manner whatsoever the Purchaser's right to
         commence an action against or in connection with the Company, 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 Purchaser's rights and remedies
         under this Agreement, the Securities Purchase Agreement and/or any
         Related Agreement or otherwise (any such action, a "Court Action").
         Court Actions may be brought by the Purchaser in any state or federal
         court of competent jurisdiction and the Company (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 7(g). In
         addition, the Purchaser may serve process in any other manner permitted
         under applicable law. If either party shall commence a Proceeding to
         enforce any provisions of this Agreement, the Securities Purchase
         Agreement or any other Related Agreement, then the prevailing party in
         such Proceeding shall be reimbursed by the other party for its
         reasonable attorneys fees and other costs and expenses incurred with
         the investigation, preparation and prosecution of such Proceeding.

         cumulative and not exclusive of any remedies provided by law.

                  (l)39.12 Severability. If any term, provision, covenant or

         remainder of the terms, provisions, covenants and restrictions set
         forth herein shall remain in full force and effect and shall in no way
         be affected, impaired or invalidated, and the parties hereto shall use
         their reasonable efforts to find and employ an alternative means to
         achieve the same or substantially the same result as that contemplated
         by such term, provision, covenant or restriction. It is hereby
         stipulated and declared to be the intention of the parties that they
         would have executed the remaining terms, provisions, covenants and
         restrictions without including any of such that may be hereafter
         declared invalid, illegal, void or unenforceable.

                Re: Epixtar Corp. Registration Statement on Form [S-1][SB-2]

Ladies and Gentlemen:

         As counsel to Epixtar Corp., a Florida corporation (the "Company"), we
have been requested to render our opinion to you in connection with the resale
by the individuals or entitles listed on Schedule A attached hereto (the
"Selling Stockholders"), of an aggregate of [amount]shares (the "Shares") of the
Company's Common Stock.

         A Registration Statement on Form [S-1][SB-2] under the Securities Act
of 1933, as amended (the "Act"), with respect to the resale of the Shares was
declared effective by the Securities and Exchange Commission on [date]. Enclosed
is the Prospectus dated [date]. We understand that the Shares are to be offered
and sold in the manner described in the Prospectus.

         Based upon the foregoing, upon request by the Selling Stockholders at
any time while the registration statement remains effective, it is our opinion
that the Shares have been registered for resale under the Act and new
certificates evidencing the Shares upon their transfer or re-registration by the
Selling Stockholders may be issued without restrictive legend. We will advise
you if the registration statement is not available or effective at any point in
the future.

                                                     Very truly yours,

                                                     [Company counsel]
