                  4.1.  Representations  and Warranties of the Company. In order
to  induce  the  Funds to enter  into this  Agreement  and to make the  Exchange
provided for herein, the Company makes the following representations, warranties
and  agreements  each as of the Closing Date unless  otherwise  specified by the
terms  thereof,  all of which shall  survive the  execution and delivery of this
Agreement and the other  Exchange  Documents and the occurrence of the Exchange,
with the occurrence of the Exchange being deemed to constitute a  representation
and warranty  that the matters  specified in this Section 4 are true and correct
in all material  respects on and as of the Closing Date (it being understood and
agreed,  however, that any representation or warranty which by its terms is made
as of a specified  date shall be required to be true and correct in all material
respects only as of such specified date):

                  (a)  Corporate  Status.  The  Company is a  corporation,  duly
incorporated,  validly existing and in good standing under the laws of the State

Exchange  Document.  Each of the Company,  Aura  Ceramics and AuraSound has duly
executed and delivered each Exchange  Document to which it is a party,  and each
such Exchange Document  constitutes the legal,  valid and binding  obligation of
the Company,  Aura Ceramics and  AuraSound  enforceable  in accordance  with its
terms,  except to the extent that the  enforceability  thereof may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium, liquidation or
similar laws relating to, or affecting  generally the enforcement of, creditors'
rights and  remedies or by other  equitable  principles  of general  application
(regardless of whether enforcement is sought in equity or at law).

                  (c)  Capitalization.  The  authorized,  issued and outstanding
capital  stock of the  Company  and its  Subsidiaries  is set forth on  Schedule

Schedule  4.1(c) hereto,  there are no  outstanding  Options,  warrants,  script
rights  to  subscribe  to,  calls or  commitments  of any  character  whatsoever
relating  to,  or  securities,   rights  or  obligations   convertible  into  or
exchangeable  for, or giving any Person any right to  subscribe  for or acquire,
any  shares of  capital  stock of the  Company  or any of its  Subsidiaries,  or
contracts, commitments,  understandings, or arrangements by which the Company or
any  Subsidiary  is or may  become  bound to issue  additional  shares of Common
Stock, or securities or rights convertible or exchangeable into shares of Common
Stock.  Neither the Company,  Aura Ceramics nor AuraSound is in violation of any
of the provisions of its  respective  certificate  of  incorporation,  bylaws or
other charter or similar organizational documents.

                  (d) Validity of the Original  Notes.  On the Closing Date, the
Original  Notes  represent  valid and binding  obligations of the Company to the
Funds  which  are  due  and  payable  in  the  aggregate   amount  of  at  least

and Warrants have been duly and validly authorized for issuance pursuant to this
Agreement  and,  when issued and  delivered as provided  hereunder in accordance
with the terms  hereof,  shall be valid and binding  obligations  of the Company

                  (f)  No  Violation.   Neither  the   execution,   delivery  or
performance  by the Company of the Secured  Notes or Warrants or of the Company,
Aura Ceramics or AuraSound of any of the other Exchange Documents nor compliance
by any of them  with the  terms  and  provisions  hereof  and  thereof,  nor the
consummation  of the  transactions  contemplated  hereby  or  thereby,  will (i)
contravene any applicable provision of any law, statute, rule or regulation,  or
any order, writ, judgment,  injunction, decree or other restriction of any court
or Authority (including Federal and state securities laws and regulations), (ii)
conflict or be inconsistent  with, or result in any breach of, any of the terms,
covenants,  conditions  or  provisions  of, or constitute a default (or an event
which with  notice or lapse of time or both would  become a default)  under,  or
give  to  others  any  rights  of   termination,   amendment,   acceleration  or
cancellation  of, or result in the creation or imposition of (or the  obligation
to create or impose) any Lien upon any of the property or assets of the Company,
Aura  Ceramics or AuraSound  pursuant to the terms of any  indenture,  mortgage,
deed of trust, loan agreement, credit agreement or any other material agreement,
Contract or  instrument  to which the Company,  Aura  Ceramics or AuraSound is a
party or by which it or any of its  property or assets is bound,  affected or to
which it may be subject (but not  including any default  arising under  Existing
Secured  Indebtedness  of the Company  owed to Imperial  Bank as a result of the
granting of Liens under the Security Documents in respect of the Secured Notes),
or (iii)  conflict  or be  inconsistent  with or violate  any  provision  of the
certificate of incorporation,  bylaws or other charter or similar organizational
document (each as amended through the date hereof) of the Company, Aura Ceramics
or AuraSound.  The businesses of the Company and its Subsidiaries have not been,
and are not  currently  being,  conducted in violation of any law,  ordinance or
regulation of any Authority, except for violations which, individually or in the
aggregate,  do not have, or could not reasonably be expected to have, a Material
Adverse Effect.

                  (g) Consents and Approvals. No consent, waiver,  authorization
or order of, or any filing or  registration  with,  any court or other  federal,
state, local or other governmental Authority or other Person (except (A) as have
been  obtained or made on or prior to the Closing  Date and which remain in full
force and effect on such date and (B) for the filing  and  effectiveness  of the
Registration  Statement  relating  to the resale of the  Shares) is  required to
authorize,  or is required in connection  with, (i) the execution,  delivery and
performance  of any Exchange  Document or (ii) the legality,  validity,  binding
effect or enforceability of any such Exchange Document.

     (h) Financial  Statements;  Financial Condition;  Undisclosed  Liabilities;
Projections; etc.

                           (A) The audited consolidated  year-end balance sheets
         of the Company for each of the fiscal years ended February 28, 1998 and
         1997 and  related  consolidated  statements  of  income,  cash flow and
         shareholders' equity of the Company and its Subsidiaries for the fiscal
         years  ended on such  dates,  copies  of which are  attached  hereto as
         Schedule 4.1(h)(A) (collectively,  the "Financial Statements"),  fairly
         present the financial  condition of the Company and its Subsidiaries as
         of such dates and the  consolidated  results of the  operations  of the
         Company  and  its  Subsidiaries  for  such  fiscal  years.  All  of the
         foregoing  financial  statements  have been  prepared (i) in accordance
         with GAAP (except as stated  therein or in the notes  thereto) and (ii)
         from the books and records of the  Company,  except that the  unaudited
         financial  statements  have no notes  attached  thereto and do not have
         year-end adjustments (none of which would be recurring). All properties
         used  in  the  Company's  business  operations  as  of  each  Financial
         Statement date are reflected in the Financial  Statements in accordance
         with and to the extent required by GAAP.

                           (B) On and as of the  Closing  Date and after  giving
         effect  to the  Exchange,  the  Restructuring  and to all  Indebtedness
         (including  under the Exchange  Documents) being incurred or assumed by
         the Company and its Subsidiaries in connection  therewith,  (i) the sum
         of the tangible and  intangible  assets,  at a fair  valuation,  of the
         Company and Aura Ceramics on a stand-alone basis and of the Company and
         its  Subsidiaries  taken as a whole will exceed their  debts;  (ii) the
         Company and Aura  Ceramics on a  stand-alone  basis and the Company and
         its  Subsidiaries  taken as a whole have not incurred and do not intend
         to incur,  and do not believe that they will incur,  debts beyond their
         ability to pay such debts as such debts  mature;  and (iii) the Company
         and Aura  Ceramics  on a  stand-alone  basis  and the  Company  and its
         Subsidiaries  taken as a whole will have sufficient  capital with which
         to conduct their  businesses.  The amount of Contingent  Obligations at
         any time  shall be  computed  as the amount  that,  in light of all the
         facts and  circumstances  existing at such time,  represents the amount
         that can  reasonably  be  expected  to  become  an  actual  or  matured
         liability.  A copy of the pro forma  consolidated  balance sheet of the
         Company after giving effect to the Exchange,  the  Restructuring and to
         all  Indebtedness   (including  under  the  Exchange  Documents)  being
         incurred or assumed by the Company and its  Subsidiaries  in connection
         therewith is attached hereto as Schedule 4.1(h)(B) hereto.

                           (C)  Except  as  fully  disclosed  in  the  Financial
         Statements and Schedule 4.1(h)(C), there were as of the Closing Date no
         Indebtedness, liabilities or obligations with respect to the Company or
         any of its  Subsidiaries of any nature  whatsoever  (whether  absolute,
         accrued,   contingent,   unliquidated  or  otherwise)   which,   either
         individually or in the aggregate, have, or could reasonably be expected
         to have, a Material Adverse Effect. As of the Closing Date, the Company
         does not know of any basis for the  assertion  against it or any of its
         Subsidiaries of any Indebtedness, liability or obligation of any nature
         whatsoever that is not fully  disclosed in the Financial  Statements or
         Schedule  4.1(h)(C)  which,  either  individually  or in the aggregate,
         have,  or could  reasonably  be  expected to have,  a Material  Adverse
         Effect.

                           (D) The  projections  delivered  to the  Agent on the
         Closing  Date  have  been  prepared  in good  faith  and are  based  on
         reasonable  assumptions,  and there are no statements or conclusions in
         the projections  which are based upon or include  information  known to
         the Company to be misleading  in any material  respect or which fail to
         take into account material  information  known to the Company regarding
         the matters reported therein. The Company believes that the projections
         are  reasonable  and  attainable,  it being  recognized  by the  Funds,
         however,  that  projections as to future events are not to be viewed as
         facts and that the actual results during the period or periods  covered
         by the projections  may differ from the projected  results and that the
         differences may be material.

                  (i) Ranking.  The Obligations  under the Secured Notes and the
other Exchange Documents  constitute and will constitute  unconditional  secured
Indebtedness of the Company and the Guarantors and, with respect to the Company,
Aura  Ceramics  and  AuraSound,  rank and will rank (i) at least  pari  passu in
priority of payment and in all other  respects with all other present and future
secured  Indebtedness  of such Persons subject to the priority rights of holders
of (A)  Existing  Secured  Indebtedness  as of the Closing  Date as set forth in
Schedule  3.18(i)(A)  hereto,  (B) validly  created and fully  perfected  senior
secured  Indebtedness  permitted under Sections 4.5(c) and 4.5(d) of the Secured
Notes incurred by the Company after the Closing Date, and (C) obligations of the
Company and Aura Ceramics and AuraSound  existing on the Execution  Date secured
by valid and  perfected  judgment  liens  against  such  Persons as set forth in
Schedule  3.18(i)(C);  provided,  however,  that the Company may supplement such
Schedule  3.18(i)(C)  to  reflect  judgment  liens  validly  created  and  fully
perfected  through the Closing  Date which the Company had no  knowledge  of and
were not identified in UCC  certificates set forth in Schedule  3.18(i)(C),  and
(ii) senior to all other Indebtedness of such Persons.

                  (j) Litigation;  Proceedings. There is no action, suit, notice
of violation,  proceeding or  investigation  pending or, to the knowledge of the
Company,  threatened against or affecting the Company or any of its Subsidiaries
or  any of  their  respective  assets  or  properties  before  or by any  court,
governmental or administrative  agency or regulatory Authority (federal,  state,
county,  local or foreign)  which (A)  relates to or  challenges  the  legality,
validity or enforceability of any transaction  contemplated hereby or any of the
Exchange  Documents,  (B) could,  individually  or in the  aggregate,  adversely
impair such Person's  ability to perform fully on a timely basis its obligations
under any of the Exchange Documents, or (C) has, or could reasonably be expected
to have, a Material  Adverse  Effect from and after the Closing Date (except for
the DFS Claims).

                  (k) No Default or  Violation.  On and as of the  Closing  Date
(except as otherwise  provided herein, in the Exchange Documents or as disclosed
in Schedule 4.1(k) hereto),  neither the Company nor Aura Ceramics:  (i) will be
in default under or in violation of any indenture,  loan or credit  agreement or
any  other  agreement  evidencing  Indebtedness  of  the  Company  or any of its
Subsidiaries  or any other  agreement or instrument to which it is a party or by
which it or any of its  properties  is  bound  (but not  including  any  default
arising under Existing Secured Indebtedness of the Company owed to Imperial Bank
as a result of the granting of Liens under the Security  Documents in respect of
the  Secured  Notes),  (ii)  will be in  violation  of any  order of any  court,
arbitrator, governmental body or Authority, or (iii) will be in violation of any
statute,  rule or regulation of any Authority,  except as could not, in any such
case,  individually  or in the  aggregate,  (A)  adversely  affect the legality,
validity or enforceability of any transaction  contemplated hereby or any of the
Exchange  Documents,  or (B) adversely  impair such Person's  ability to perform
fully on a timely basis its obligations under any of the Exchange Documents,  or
(C) has, or could reasonably be expected to have, a Material Adverse Effect.

                  (l) Indebtedness. Schedule 4.1(l) hereto sets forth a true and
complete list (subject to variances not to exceed seven and one-half  percent (7
1/2%) in the aggregate) of all Indebtedness  (excluding  Indebtedness  under the
Secured Notes and the other Exchange  Documents) of the Company,  Aura Ceramics,
and Aura Realty as of the Execution Date and which is to remain outstanding (the
"Existing  Indebtedness"),  in each case showing the aggregate  principal amount
thereof,  accrued  interest in respect  thereof and the name of any Person which
directly or indirectly guaranteed such debt.

                  (m) True and  Complete  Disclosure.  All  factual  information
(taken  as a whole)  furnished  by or on  behalf  of the  Company  or any of its
Subsidiaries in writing to the Agent or any Fund (including, without limitation,
all  information  contained  in the  Exchange  Documents)  for purposes of or in
connection with this Agreement,  any other Exchange  Document or any transaction
contemplated hereby or thereby is, and all other such factual information (taken
as a whole)  hereafter  furnished  by or on behalf of the  Company or any of its
Subsidiaries  in writing to the Agent or any Fund will be, true and  accurate in
all  material  respects  on the date as of which  such  information  is dated or
certified  and not  incomplete  by omitting to state any fact  necessary to make
such  information  (taken as a whole) not misleading in any material  respect at
such  time in  light of the  circumstances  under  which  such  information  was
provided.  There is no fact which the Company has not  disclosed to the Agent or
the Funds herein and of which the  Company,  its  Subsidiaries,  or any of their
respective officers, directors or executive employees is aware and which has, or
could reasonably be expected to have, a Material Adverse Effect.

                  (n)      Use of Proceeds; Margin Regulations.

                           (A) All proceeds of the  Original  Notes were used by
         the Company for general corporate purposes.

                           (B) No part of the proceeds of any Original Note were
         used (i) to purchase or carry any Margin Stock or to extend  credit for
         the purpose of  purchasing  or carrying  any Margin  Stock or to refund
         indebtedness  originally  incurred  for  such  purpose  or (ii) for any
         purpose  which  violated or was  inconsistent  with the  provisions  of
         Regulations G, T, U or X of the Board of Governors of the United States
         Federal Reserve System.

4.1(o) hereto, each of the Company, Aura Ceramics, AuraSound and Aura Realty (A)

years and for the current  fiscal year to date.  Except as disclosed in Schedule
4.1(o) hereto,  there is no material action,  suit,  proceeding,  investigation,

Subsidiaries,  threatened by any Authority  regarding any taxes relating to such
Person. As of the Execution Date, neither the Company, Aura Ceramics, AuraSound,

such Person not to be subject to the normally applicable statute of limitations.

         Internal  Revenue Service to the effect that it meets the  requirements

         threatened;   using  actuarial   assumptions  and  computation  methods
         consistent  with  Part  1 of  subtitle  E of  Title  IV of  ERISA,  the
         aggregate liabilities of the Company and its Subsidiaries and its ERISA
         Affiliates  to all Plans which are  multiemployer  plans (as defined in
         Section  4001(a)(3)  of ERISA) in the  event of a  complete  withdrawal
         therefrom,  as of the close of the most recent fiscal year of each such
         Plan ended prior to the Closing Date, would not exceed  $100,000;  each
         group  health  plan (as  defined in Section  607(1) of ERISA or Section
         4980B(g)(2)  of the Code)  which  covers or has  covered  employees  or

         assets of the  Company or any  Subsidiary  of the  Company or any ERISA
         Affiliate  exists or is likely to arise on account of any Plan; and the
         Company and its  Subsidiaries  may cease  contributions to or terminate
         any employee  benefit plan maintained by any of them without  incurring
         any material liability.

                           (B) Neither  the Company nor any of its  Subsidiaries
         has, or has ever had, a Foreign Pension Plan.

                  (q) Compliance with Law and Applicable Government Regulations.
Each of the Company and its  Subsidiaries is presently in compliance with regard
to its operations,  practices,  real property,  plants,  structures,  machinery,
equipment and other  property,  and all other aspects of its business,  with all
applicable  Regulations  and  Orders,   including,   but  not  limited  to,  all
Regulations relating to the safe conduct of business,  environmental protection,
quality and labeling,  antitrust, Taxes, consumer protection, equal opportunity,
discrimination,  health,  sanitation,  fire,  zoning,  building and occupational
safety, except for such non-compliances which, individually or in the aggregate,
would not have, or could not reasonably be expected to have, a Material  Adverse
Effect.  There are no Claims pending or, to the Company's knowledge  threatened,
nor has the Company  received any written notice regarding any violations of any
Regulations  or Orders  enforced by any Authority  including any  requirement of
OSHA or any pollution and environmental control agency (including air and water)
that have, or could reasonably be expected to have, a Material Adverse Effect.

                  (r) Security Documents. The provisions of each of the Security
Documents  will,  on the  Closing  Date,  create in favor of the Agent,  for the
benefit of the Funds,  as security for the  Obligations  hereunder and under all
other Exchange  Documents,  a valid and enforceable  security interest in all of
the right,  title and interest of the relevant assignor or pledgor thereunder in
and to the  Collateral  described  therein  superior to all Liens subject to the
priority  rights of holders of Permitted Liens of the types described in clauses
(c) and (i) of Section 4.1 of the Secured Notes (and any  extension,  renewal or
replacement  thereof to the extent  permitted  by Section  4.1(k) of the Secured
Notes).

                  (s) Investment Company Act. Neither the Company nor any of its
Subsidiaries  is  an  "investment  company"  or a  company  "controlled"  by  an
"investment company," within the meaning of the United States Investment Company
Act of 1940, as amended.

                  (t) Public Utility  Holding  Company Act.  Neither the Company
nor any of its Subsidiaries is a "holding company," or a "subsidiary company" of
a  "holding  company,"  or  an  "affiliate"  of  a  "holding  company"  or  of a
"subsidiary  company"  of a "holding  company"  within the meaning of the United
States Public Utility Holding Company Act of 1935, as amended.

                  (u) Labor Relations.  Each of the Company and its Subsidiaries
is in  compliance  with all  federal,  state  and  local  Regulations  or Orders
affecting  employment and employment  practices  applicable to each such Person,
including  terms and  conditions of employment  and wages and hours,  except for
certain failure to make salary or other compensation  payments to management and
such non-compliances which, individually or in the aggregate, would not have, or
could not reasonably be expected to have, a Material Adverse Effect. The Company
and its  Subsidiaries  have no collective  bargaining  agreements and there have
been no strikes,  work stoppages or any demands for collective bargaining by any
union or labor organization.  Neither the Company nor any of its Subsidiaries is
engaged in any unfair labor  practice that has, or could  reasonably be expected
to have,  a  Material  Adverse  Effect.  There is (A) no unfair  labor  practice
complaint pending against the Company or any of its Subsidiaries or, to the best
knowledge  of  the  Company,  threatened  against  the  Company  or  any  of its
Subsidiaries, and no grievance or arbitration proceeding arising out of or under
any collective bargaining agreement is pending against the Company or any of its
Subsidiaries  or, to the best knowledge of the Company,  threatened  against the
Company or any of its Subsidiaries,  (B) no strike,  labor dispute,  slowdown or
stoppage is pending  against the Company or any of its  Subsidiaries  or, to the
best  knowledge  of the  Company,  threatened  against the Company or any of its
Subsidiaries   and  (C)  to  the  best  knowledge  of  the  Company,   no  union
representation question is existing with respect to the employees of the Company
or any of its Subsidiaries  and, to the best knowledge of the Company,  no union
organizing  activities  are taking  place,  except  (with  respect to any matter
specified  in  clause  (A),  (B) or (C)  above,  either  individually  or in the
aggregate)  which does not have, or could not  reasonably be expected to have, a
Material Adverse Effect.

                  (v)  Proprietary  Rights,  Licenses,  Franchises and Formulas.
Each of the Company and its Subsidiaries owns all Proprietary Rights,  licenses,
franchises and formulas, or rights with respect to any of the foregoing, and has
obtained assignments of all leases and other rights of whatever nature necessary
for the present  conduct of its  business,  without any known  conflict with the
rights of others which, or the failure to obtain which, as the case may be, has,
or could reasonably be expected to have, a Material Adverse Effect.  To the best
knowledge  of the  Company,  no claim is pending  that the Company or any of its
Subsidiaries  infringes  upon the asserted  rights of any other Person under any
intellectual property, except for claims which could not, individually or in the
aggregate, have, or could not reasonably be expected to have, a Material Adverse
Effect.  To the best  knowledge  of the  Company,  no claim is pending that such
intellectual   property  owned  or  licensed  by  the  Company  or  any  of  its
Subsidiaries or which such Person  otherwise has the right to use is invalid and
unenforceable,  except  for  claims  which  could  not,  individually  or in the
aggregate,  have, or reasonably be expected to have, a Material  Adverse Effect.
The consummation of the transactions  contemplated hereby or by any of the other
Exchange  Documents will not alter or impair any rights of the Company or any of
its  Subsidiaries  to use any  intellectual  property  in a way that  would not,
individually or in the aggregate, have, or could reasonably be expected to have,
a Material Adverse Effect.  The Company is the legal and beneficial owner of all
right,  title and interest in, to and under the Proprietary  Rights with respect
to AuraGen,  and the Company has not entered into any agreement or understanding
with  any  Person  concerning  any  sale,  lease,  transfer,   option,  license,
assignment or other disposition of such Proprietary Rights, other than the grant
of security interests in connection with Permitted Liens.

                  (w) Certain Fees. No fees or commission will be payable by the
Company to any broker,  finder,  investment  banker or bank with  respect to the
consummation  of the  transactions  contemplated  hereby  or by any of the other
Exchange Documents.

                  (x)  Private  Offering.  The offer,  issuance  and sale of the
Secured Notes pursuant to this Agreement are exempt from registration  under the
Securities  Act.  Neither the  Company  nor any person  acting on its behalf has
taken or will take any action (including,  without  limitation,  any offering of
any  securities  of the Company  under  circumstances  which  would  require the
integration  of such  offering  with the offering of the Secured Notes under the
Securities  Act) which  might  subject  the  offering,  issuance  or sale of the
Secured Notes to the registration requirements of the Securities Act.

                  (y) SEC  Documents.  Attached  hereto as Schedule  4.1(y) is a
true and complete list of all forms,  reports and documents required to be filed

                  (z) Directors and  Management  Compensation.  Schedule  4.1(z)
hereto sets forth a list of all officers,  directors and key employees  (meaning
those earning more than $50,000.00  annually  including all bonuses and non-cash

of their  respective  positions and total  compensation  and a list of all other
outstanding  obligations owed by the Company to each of such Persons.  On and as
of the  Closing  Date,  the  Company  and its  Subsidiaries  will  not  have any
liability to any of their employees,  officers or directors (except as set forth
in Schedule  4.1(z)) other than for the payment of salaries and director fees to
be paid in the ordinary course of business.

                  (aa)  Absence of Certain  Changes.  Since  November  30, 1998,
except as fully  disclosed on Schedule  4.1(aa) hereto or otherwise  provided in
this  Agreement,  there  has not been any (a)  material  adverse  change  in the
business,  operations,  properties,  assets, condition (financial or otherwise),

into any material  Contract not in the ordinary  course of business,  including,
without  limitation,  any  borrowing or capital  expenditure;  (f) change by the
Company or any of its Subsidiaries in accounting  methods or principles;  or (g)
consensual Lien placed on any property of the Company or any of its Subsidiaries
other than Permitted Liens.

                  (bb) Year 2000 Compliance.  As of the Closing Date,  except as
set forth on Schedule 4.1(bb) hereto, all Date Data and Date-Sensitive  Systems,
if any, of the Company and its Subsidiaries are Year 2000 Compliant. The Company
and its Subsidiaries  have obtained written  representations  or assurances from
each  entity  that  (x)  provides  Date  Data  to  the  Company  or  any  of its
Subsidiaries,  or (y)  processes  in any way Date Data for the Company or any of
its  Subsidiaries or otherwise  provides any material  product or service to the
Company or any of its Subsidiaries that is dependent on Year 2000 Compliant Date
Data or a Year 2000 Compliant  Date-Sensitive  System, that all of such entity's
Date Data and  Date-Sensitive  Systems  that are used for,  or on behalf of, the
Company or any of its Subsidiaries are Year 2000 Compliant.

     (cc) Capital Expenditures and Investments. Each Contract of the Company and
its  Subsidiaries for capital  expenditures  and investments  entered into on or

                  (dd) Dealings with  Affiliates.  Schedule  4.1(dd) hereto sets
forth a complete  and  accurate  list,  including  the  parties,  of all oral or
written Contracts to which the Company and its Subsidiaries are, will be or have
been a party,  at any time from  November 30, 1998 to and  including the Closing
Date, and to which any one or more of their  Affiliates is also a party.  Except
as set forth on Schedule  4.1(dd)  hereto,  since November 30, 1998, the Company
and its Subsidiaries have not made any payments, loaned any funds or property or
made any credit arrangement with any Affiliate or employee of the Company or any
of its  Subsidiaries  except for the payment of employee  salaries  and director
compensation in the ordinary course of business.

     (ee) Solicitation  Materials.  The Company did not solicit any offer to buy
or sell the  Secured  Notes by means  of any  form of  general  solicitation  or
advertising.

                  (ff)  Assignment  of  NewCom   Promissory  Note.  The  Company
acknowledges,  confirms and ratifies the assignment and transfer to the Funds by
delivery to the Agent of that certain  Promissory  Note dated September 19, 1997
payable by NewCom to the order of the Company in the original  principal  amount
of $17,000,000.00  due September 20, 1998 (the "NewCom Note") and further agrees
with the Funds that it shall take such  further  actions,  give such notices and
deliver such further written  instruments as the Funds may reasonably request in
order to  effectuate  such  assignment  and  transfer  and to  provide  benefits
thereof.  The  NewCom  Note  shall be held by the Agent for the  benefit  of the
Funds.  The  Company  further  acknowledges  and agrees  with the Funds that any
amount paid to them under or  pursuant to the NewCom Note shall be the  property
of such Funds and the Company hereby releases any claim,  demand or right it may
now or  hereafter  have or acquire with respect to the NewCom Note or any amount
paid or payable thereunder.  Notwithstanding the above, each of the Funds agrees
that,  prior  to  April  30,  2000,  it will  not (i)  commence  an  involuntary
bankruptcy proceeding against NewCom and (ii) at any time assert in any judicial
proceeding  or  otherwise  that the  Company is  NewCom's  alter ego or that the
Company is obligated to the Funds thereunder.

                  4.2.  Representations and Warranties of the Funds. Each of the
Funds, severally and not jointly,  hereby represents and warrants to the Company
as follows:

                  (a)  Ownership of Original  Notes.  Such Fund is the legal and
beneficial owner of the Original Notes to be exchanged  hereunder,  as specified
in Section 2.1.

                  (b)  Organization;  Authority.  Such  Fund is an  entity  duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction of its organization with the requisite power and authority to enter
into and to consummate  the  transactions  contemplated  hereby and otherwise to
carry out its  obligations  hereunder and  thereunder.  The  acquisition  of the
Secured Notes by such Fund  hereunder has been duly  authorized by all necessary
action on the part of such  Fund.  This  Agreement  has been duly  executed  and
delivered by such Fund (by and through its authorized Agent) and constitutes the
valid and legally  binding  obligation of such Fund,  enforceable  against it in
accordance with its terms, except to the extent that the enforceability  thereof
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium,
liquidation or similar laws relating to, or affecting  generally the enforcement
of, creditors'  rights and remedies or by other equitable  principles of general
application (regardless of whether enforcement is sought in equity or at law).

                  (c) Fund Status. At the time such Fund was offered the Secured
Notes to be exchanged by it hereunder, it was, and at the date hereof, it is, an
"accredited investor" as defined in Rule 501(a) under the Securities Act.

                  (d)  Experience  of the Fund.  In  reliance  on the  Company's
representations  and warranties herein, such Fund, either alone or together with
its  representatives,  has such  knowledge,  sophistication  and  experience  in
business and financial  matters so as to be capable of evaluating the merits and
risks of an investment in the securities to be acquired by it hereunder, and has
so evaluated the merits and risks of such investment.

                  (e) Ability of the Fund to Bear Risk of Investment.  Such Fund
is able to bear the  economic  risk of an  investment  in the  securities  to be
acquired by it hereunder  and, at the present time, is able to afford a complete
loss of such investment.

                  The  Company  acknowledges  and agrees  that the Agent and the
Funds make no  representations  or warranties  with respect to the  transactions
contemplated hereby other than those specifically set forth in this Section 4.2.

                  SECTION 5.        Other Agreements of the Parties.

                  5.1.     Transfer Restrictions.

                  (a) If any Fund should decide to dispose of any of the Secured
Notes,  such Fund  understands and agrees that it may do so only (i) pursuant to
an effective  registration  statement under the Securities Act, or (ii) pursuant
to an available exemption from registration under the Securities Act.

                  (b) The Funds agree to the imprinting,  so long as required by
the terms of the Securities Act, of the following legend on each Secured Note:

                  NEITHER  THIS  SECURED   NOTE  NOR  THE   GUARANTIES   OF  THE
                  SUBSIDIARIES  HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF
                  1933, AS AMENDED (THE "SECURITIES  ACT"), OR THE "BLUE SKY" OR
                  SECURITIES  LAWS OF ANY STATE BY REASON OF THEIR ISSUANCE IN A
                  TRANSACTION  EXEMPT FROM THE REGISTRATION  REQUIREMENTS OF THE
                  SECURITIES   ACT  OR  SUCH   STATE   SECURITIES   LAWS,   AND,
                  ACCORDINGLY,  MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
                  EFFECTIVE  REGISTRATION  STATEMENT UNDER THE SECURITIES ACT OR
                  PURSUANT  TO AN  AVAILABLE  EXEMPTION  FROM  THE  REGISTRATION
                  REQUIREMENTS  THEREUNDER,  AND IN COMPLIANCE  WITH  APPLICABLE
                  STATE SECURITIES LAWS.

                  The legend set forth above shall be removed as soon as allowed
under the Securities Act or the regulations promulgated thereunder.  The Company
agrees that it will provide each Fund, upon request,  with any required  opinion
of counsel and a replacement Secured Note, free from such legend at such time as
such legend is no longer applicable, at no charge.

                  5.2. Blue Sky Laws. The Company shall qualify the Shares under
the securities or "Blue Sky" laws of such jurisdictions as each Fund may request
and shall continue such  qualification at all times as long as any Fund owns any
Shares.

                  5.3. Integration. The Company shall not and shall use its best
efforts  to ensure  that no  Affiliate  shall,  sell,  offer for sale or solicit
offers to buy or otherwise negotiate in respect of any "security" (as defined in
Section 2 of the Securities Act) that would be integrated with the offer or sale
of the  Secured  Notes  or  the  Shares  in a  manner  that  would  require  the
registration  under the  Securities  Act of the sale of the Secured Notes or the
Shares to the Funds.

                  SECTION 6.        Miscellaneous.

                  6.1.  Fees and  Expenses.  The Company and the Funds shall pay
the fees and expenses of their  respective  advisors,  counsel,  accountants and
other  experts,  if  any,  and  all  other  expenses  incurred  incident  to the
negotiation,  preparation, execution, delivery and performance of this Agreement
and the other  Exchange  Documents.  The  Company  shall pay all stamp and other
taxes (other than income) and duties levied in  connection  with the issuance of
the Secured Notes and Shares pursuant hereto or any other Exchange Document.

                  6.2.     Indemnification.

                  (a) Except with respect to litigation  concerning the priority
of Permitted  Liens or  assertions  by the Company in  accordance  with the last
sentence  of  Section  2.1 of the  Security  Agreement,  the  Company  agrees to
indemnify and hold harmless,  to the extent permitted by law, the Agent and each
Fund  and  their  respective  officers  and  directors,   employees,   advisors,
attorneys,  agents, and  representatives  against any and all claims,  causes of
action,  losses,  liabilities,  damages or expenses incurred by any of them as a
result of, arising out of, or in any way related to, or by reason of, any breach
or default by the Company  under any  provision  of this  Agreement or any other
Exchange Document,  including,  but not limited to, any breach by the Company of
its representations and warranties set forth in Section 4.1 hereto.

                  (b) Any person entitled to indemnification hereunder shall (i)
give prompt written notice to the  indemnifying  party of any claim with respect
to which it seeks  indemnification  and (ii) unless in such indemnified  party's
reasonable  judgment  a  conflict  of  interest  between  such  indemnified  and
indemnifying  parties  may  exist  with  respect  to  such  claim,  permit  such
indemnifying  party to assume the defense of such claim with counsel  reasonably
satisfactory  to  the  indemnified  party.  If  such  defense  is  assumed,  the
indemnifying party shall not be subject to any liability for any settlement made
by the  indemnified  party  without its consent (but such  consent  shall not be
unreasonably  withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim shall not be obligated to pay the fees and
expenses  of  more  than  one  counsel  for  all  parties  indemnified  by  such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any  indemnified  party  a  conflict  of  interest  may  exist  between  such
indemnified party and any other of such indemnified parties with respect to such
claim.

                  (c) The  indemnification  provided  for under  this  Agreement
shall remain in full force and effect regardless of any investigation made by or
on behalf of the  indemnified  party or any  officer,  director  or  controlling
person of such  indemnified  party and shall survive the transfer of securities.
The Company also agrees to make such provisions,  as are reasonably requested by
any indemnified party, for contribution to such party in the event the Company's
indemnification is unavailable for any reason.

                  6.3.  Entire  Agreement;  Amendments.  This  Agreement and the
other Exchange  Documents,  together with the exhibits and schedules  hereto and
thereto,  contain the entire  understanding  of the parties  with respect to the
subject  matter hereof and supersede all prior  agreements  and  understandings,
oral or written, with respect to such matters.

                  6.4. Notices.  Any and all notices or other  communications or
deliveries  required or permitted to be provided  hereunder  shall be in writing
and  shall be deemed  given and  effective  on the  earliest  of (i) the date of
transmission,  if such notice or communication is delivered via facsimile at the
facsimile telephone number specified in this Section 6.4 prior to 4:30 p.m. (New

be waived or amended except in a written  instrument  signed,  in the case of an
amendment,  by both the Company and the Agent,  or, in the case of a waiver,  by
the party against whom  enforcement  of any such waiver is sought.  No waiver of

any other  provision,  condition or requirement  hereof,  nor shall any delay or
omission of either  party to exercise any right  hereunder in any manner  impair
the exercise of any such right accruing to it thereafter.

     6.6. Headings Descriptive. The headings herein are for convenience only, do
not  constitute  a part of this  Agreement  and  shall not be deemed to limit or
affect any of the provisions hereof.

Funds) may sell, assign, transfer or grant participations in all or a portion of
its rights and outstanding Obligations hereunder and under the Secured Notes and

Agreement  as a Fund,  provided  that new  Secured  Notes and  Warrants  will be
issued,  at the Company's  expense,  to such new Fund and to the assigning  Fund

Warrants to be in conformity  with the  requirements of Section 2.1 hereof (with

outstanding  Obligations).  The  assigning  Fund will  notify the Company of any
assignment pursuant to this Section 6.7(b); provided,  however, that the failure
to give any such notice,  or any error in such  notice,  shall not affect any of
the obligations of the Company hereunder or under any other Exchange Document.

Fund from  pledging its rights  hereunder  or under any of the Secured  Notes or
Warrants.

                  6.8. No Third-Party Beneficiaries.  This Agreement is intended

THIS AGREEMENT,  EACH PARTY HEREBY IRREVOCABLY ACCEPTS FOR ITSELF AND IN RESPECT

AFFECT THE RIGHT OF THE AGENT,  ANY FUND OR THE  HOLDER OF ANY  SECURED  NOTE OR
ORIGINAL  NOTE TO SERVE  PROCESS  IN ANY  OTHER  MANNER  PERMITTED  BY LAW OR TO

INDUCEMENT FOR THE PARTIES HERETO TO ENTER INTO THIS AGREEMENT.

                  6.10.  Counterparts.  This Agreement may be executed in two or
more counterparts,  all of which when taken together shall be considered one and
the same agreement and shall become effective when counterparts have been signed
by each party and delivered to the other party,  it being  understood  that both
parties need not sign the same  counterpart.  In the event that any signature is
delivered by facsimile  transmission,  such  signature  shall create a valid and
binding  obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile signature
page were an original thereof.

                  6.11. Publicity.  The Company and the Agent shall consult with
each other in issuing any press releases or otherwise  making public  statements
with respect to the  transactions  contemplated  hereby and neither  party shall
issue any such press release or otherwise make any such public statement without
the prior written consent of the other,  which consent shall not be unreasonably
withheld or delayed, except for such releases, filings or public statements that
are  required  by  law or any  regulatory  body  or  governmental  authority  of
competent jurisdiction.

                  6.12.    Confidentiality.

                  (a)  Each  of  the  Funds   and  the  Agent   agrees  to  keep
confidential any non-public  information supplied to it by the Company or any of
its  Subsidiaries  pursuant to this  Agreement or any other  Exchange  Document;
provided,  however,  that nothing  herein shall limit the disclosure of any such
information (i) to the extent required by statute,  rule, regulation or judicial
process,  (ii) to  counsel  for any of the  Funds  or the  Agent so long as such
counsel  confirms  it shall  keep the  non-public  information  confidential  in
accordance  with these  provisions,  (iii) to auditors or  accountants or to any
other   regulatory   agency   or   body   with   proper   authority   (including
non-governmental  regulatory agencies or bodies),  (iv) to any other Fund or the
Agent,  (v) in  connection  with any  litigation to which any one or more of the
Funds or the Agent is a party where  disclosure of such  information  is, in the
opinion  of  counsel  for any  Fund or the  Agent,  necessary  or  advisable  in
connection with any action,  claim, suit or proceeding,  directly or indirectly,
involving  or  potentially  involving  any Fund or the Agent and arising out of,
based upon,  relating  to or  involving  this  Agreement  or any other  Exchange
Document,  or  any  transactions  contemplated  hereby  or  thereby  or  arising
hereunder or thereunder, (vi) to any subsidiary,  Affiliates, director, officer,
employee or representative of any Fund or of the Agent, (vii) to any assignee or
participant (or prospective  assignee or participant) so long as any such Person
confirms in writing that it shall keep the non-public  information  confidential
in accordance with these provisions,  or (viii) to any credit rating agency that
rates the financial  condition of any Fund or the claims  paying  ability of any
Fund,  provided  that  such  credit  rating  agency  agrees in  writing  to keep
confidential  any non-public  information  provided by the Company or any of its
Subsidiaries;  provided  further that in no event shall any Fund or the Agent be
obligated or required to return any  materials  furnished by or on behalf of the
Company or any of its Subsidiaries.

                  (b) Each of the Funds and the Agent  shall  inform the Company
in writing of the name and  address of any of the Persons  described  in clauses
(vii) and (viii) of Section 6.12(a) above to whom any non-public  information of
the  Company  or any  Subsidiary  shall  have  been  provided,  together  with a
description of the  information  so provided,  in each case within five Business
Days of the delivery to any such Person of any such non-public information.

                  6.13. Severability.  In case any one or more of the provisions
of this Agreement shall be invalid or unenforceable in any respect, the validity
and enforceability of the remaining terms and provisions of this Agreement shall
not in any way be affected or impaired  thereby and the parties  will attempt to
agree  upon a valid  and  enforceable  provision  which  shall  be a  reasonable
substitute  therefor,  and upon so agreeing,  shall  incorporate such substitute
provision in this Agreement.

                  6.14. Remedies.  In addition to being entitled to exercise all
rights provided  herein or granted by law,  including  recovery of damages,  the
Company  and  the  Funds  will  be  entitled  to  specific  performance  of  the
obligations under this Agreement.  The Company and the Funds agree that monetary
damages  would not be adequate  compensation  for any loss incurred by reason of
any breach of their respective  obligations  described in the foregoing sentence
and hereby  agree to waive in any action for  specific  performance  of any such
obligation the defense that a remedy at law would be adequate.

                  GUARANTY, dated as of February 22, 2000 (the "Guaranty"), made
by each of AURA  CERAMICS,  INC.,  a  Delaware  corporation  ("Aura  Ceramics"),
AURASOUND,  INC., a Delaware  corporation  ("AuraSound"),  AURA MEDICAL SYSTEMS,
INC., a Delaware corporation ("Aura Medical"),  ELECTROTEC PRODUCTIONS,  INC., a
California  corporation  ("Electrotec  Productions"),  DS  OSCILLATOR,  INC.,  a
California  corporation  ("DS  Oscillator"),  PHILIPS SOUND LABS, INC., a Nevada
corporation  ("Philips Sound") and ELECTROTEC AUDIO LEASE LIMITED, a corporation
organized  and  existing  under  the laws of  England  ("Electrotec  Audio"  and
together with the Company, Aura Ceramics,  AuraSound,  Aura Medical,  Electrotec
Productions,   DS  Oscillator,   and  Philips  Sound,  each  a  "Guarantor"  and
collectively,  the "Guarantors").  Unless the context otherwise requires,  terms
used herein and defined in the Secured  Notes (as defined  below)  shall be used
herein as so defined.

                              W I T N E S S E T H :

                  WHEREAS,  each Guarantor is a wholly owned  subsidiary of Aura
Systems, Inc., a Delaware corporation (the "Company").

                  WHEREAS,  each of Infinity Investors Limited,  Glacier Capital
Limited,  Global Growth Limited and Summit Capital  Limited  (collectively,  the
"Funds"),  is the holder of certain Variable Interest Rate Convertible Notes due
September 30, 1998 (the "Original  Notes") of the Company,  which are secured by
certain  assets of the Company as  specified in that  certain  Pledge  Agreement
dated September 30, 1997;

                  WHEREAS, on the date hereof the Company will issue and deliver
Secured Notes of even date herewith in an aggregate amount of $12,500,000.00 (as
modified, supplemented or amended from time to time, the "Secured Notes") to the
Funds in exchange  for Original  Notes held by the Funds after giving  effect to
the Assignment (the "Exchange");

                  WHEREAS, it is a condition to the Exchange that each Guarantor
shall have executed and delivered this Guaranty; and

                  WHEREAS,  each Guarantor  obtained benefits as a result of the
proceeds of the Original Notes and, thus, of the  Obligations  evidenced by each
Secured Note and,  accordingly,  desires to execute and deliver this Guaranty in
order to satisfy the condition described in the preceding paragraph;

                  NOW,  THEREFORE,  in  consideration of the foregoing and other
benefits  accruing to each  Guarantor,  the receipt and sufficiency of which are
hereby acknowledged,  each Guarantor hereby makes the following  representations
and  warranties to the Funds and hereby  covenants and agrees with the Agent and
each Fund as follows:

                  1. Each Guarantor  irrevocably and unconditionally  guarantees
the full and prompt payment when due (whether by  acceleration  or otherwise) of
the  principal  of and  interest  on any of the  Secured  Notes  and  all  other
Obligations  (including,  without  limitation,  indemnities,  fees and  interest
thereon) of the Company and each  Guarantor  now existing or hereafter  incurred
under,  arising  out of or in  connection  with the  Secured  Notes or any other
Transaction  Document and the due  performance  and compliance with the terms of
the Transaction Documents by the Company and each Guarantor (all such principal,
interest, and other Obligations,  collectively,  the "Guaranteed  Obligations").
All payments by the  Guarantors  under this  Guaranty  shall be made on the same
basis as payments by the Company under the Secured Notes.

                  2. Each  Guarantor  hereby waives notice of acceptance of this
Guaranty  and  notice  of any  liability  to  which  it may  apply,  and  waives
presentment, demand of payment, protest, notice of dishonor or nonpayment of any
such liability, suit or taking of other action by the Agent or any Fund against,
and any other notice to, any party liable thereon (including such Guarantor).

                  3. The  Agent  and any  Fund may at any time and from  time to
time  without  the consent of, or notice to the  Guarantors,  without  incurring
responsibility  to  the  Guarantors  and  without  impairing  or  releasing  the
obligations of the Guarantors hereunder, upon or without any terms or conditions
and in whole or in part:

                  (a) change the manner,  place or terms of payment  of,  and/or
         change or extend the time of  payment  of,  renew or alter,  any of the
         Guaranteed  Obligations,   any  security  therefor,  or  any  liability
         incurred  directly or indirectly in respect  thereof,  and the Guaranty
         herein made shall apply to the  Guaranteed  Obligations  as so changed,
         extended, renewed or altered;

                  (b)  sell,  exchange,  release,  surrender,  realize  upon  or
         otherwise  deal with in any  manner  and in any order any  property  by
         whomsoever  at any time pledged or  mortgaged  to secure,  or howsoever
         securing,  the Guaranteed Obligations or any liabilities (including any
         of those hereunder)  incurred directly or indirectly in respect thereof
         or hereof, and/or any offset thereagainst;

                  (c) exercise or refrain from exercising any rights against the
         Company or others or otherwise act or refrain from acting;

                  (d) settle or compromise  any of the  Guaranteed  Obligations,
         any  security  therefor  or  any  liability  (including  any  of  those
         hereunder)  incurred  directly  or  indirectly  in  respect  thereof or
         hereof,  and may  subordinate the payment of all or any part thereof to
         the  payment of any  liability  (whether  due or not) of the Company to
         creditors of the Company other than the Funds and the Guarantors;

                  (e) apply any sums by whomsoever paid or howsoever realized to
         any Obligations of the Company to the Agent or the Funds  regardless of
         what Obligations of the Company remain unpaid; and/or

                  (f) consent to or waive any breach of, or any act, omission or
         default under,  any of the Transaction  Documents,  or otherwise amend,
         modify or supplement  any of the  Transaction  Documents or any of such
         other instruments or agreements.

                  4.  Obligations of each Guarantor under this Guaranty shall be
secured by that certain Security Agreement,  dated as of the date hereof,  among
each of the Company, each Guarantor and HW Partners,  LP, as agent for the Funds
(as  modified,  supplemented  or  amended  from  time  to  time,  the  "Security
Agreement").

                  5.  Obligations  of each  Guarantor  under this  Guaranty  are
absolute and  unconditional  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  action  or  inaction  by the Agent or any Fund as
contemplated in Section 3 of this Guaranty; or (b) any invalidity,  irregularity
or  unenforceability  of all or part  of the  Guaranteed  Obligations  or of any
security therefor (including,  without limitation, the Security Agreement). This
Guaranty is a primary obligation of each Guarantor. The entirety of this Section
5 notwithstanding, prior to the occurrence of an Event of Default (which has not
been cured in accordance with the terms of the Secured  Notes),  the obligations
of a  Guarantor  under this  Guaranty  shall be released  concurrently  with the
closing of the sale of all of the capital stock of such  Guarantor in accordance
with  Section  4.3(d) of the  Secured  Notes,  and the Agent and the Funds shall
execute all documents reasonably required by such purchaser to so evidence.

                  6. If and to the extent that any  Guarantor  makes any payment
to the Agent, any Fund, the holder of any Secured Note or to any other Person in
satisfaction of such Guarantor's  Guaranteed  Obligations under this Guaranty or
any other Transaction Document,  any claim which such Guarantor may have against
the  Company  by  reason  thereof,  including,  without  limitation,  by  way of
contribution, reimbursement or subrogation, is hereby waived, and such Guarantor
shall have no recourse  against  the  Company or its assets with  respect to any
such claims.

                  7. In order to induce the Funds to exchange the Original Notes
for the Secured Notes, each Guarantor  (except where otherwise  indicated below)
makes the following representations, warranties and agreements:

                  (a)  Each  of  Aura  Ceramics  and  AuraSound  (i)  is a  duly
         organized and validly  existing  corporation in good standing under the
         laws of the jurisdiction of its  incorporation,  (ii) has the power and
         authority  to own its  property and assets and to transact the business
         in  which  it  is  engaged,  (iii)  is  duly  qualified  as  a  foreign
         corporation  and in  good  standing  in  each  jurisdiction  where  the
         ownership,  leasing or  operation of its property or the conduct of its
         business  requires  such  qualification,  except for  failures to be so
         qualified or in good standing, as the case may be, which,  individually
         or in the  aggregate,  could  not  reasonably  be  expected  to  have a
         Material Adverse Effect, and (iv) has no subsidiaries.

                  (b) The Guarantor has the corporate power to execute,  deliver
         and perform the terms and provisions of this Guaranty and has taken all
         necessary  corporate  action to authorize the  execution,  delivery and
         performance  by it of this  Guaranty.  Each Guarantor has duly executed
         and delivered this Guaranty,  and this Guaranty  constitutes its legal,
         valid and binding obligation enforceable in accordance with its terms.

                  (c) Neither the  execution,  delivery or  performance  by each
         Guarantor of this  Guaranty,  nor  compliance  by it with the terms and
         provisions  hereof,  (i)  will  contravene  any  provision  of any law,
         statute, rule or regulation or any order, writ, injunction or decree of
         any court or  governmental  instrumentality,  (ii) will  conflict or be
         inconsistent  with  or  result  in any  breach  of  any  of the  terms,
         covenants,  conditions or provisions of, or constitute a default under,
         or result in the creation or imposition of (or the obligation to create
         or  impose)  any  Lien  upon  any of the  property  or  assets  of such
         Guarantor  pursuant to the terms of any  indenture,  mortgage,  deed of
         trust,  credit  agreement,  loan  agreement  or  any  other  agreement,
         contract or instrument  to which such  Guarantor is a party or by which
         it or any of its  property  or  assets  is  bound or to which it may be
         subject or (iii) will  violate  any  provision  of the  certificate  of
         incorporation or by-laws of such Guarantor.

                  (d) With  respect to Aura  Ceramics and  AuraSound,  no order,
         consent, approval, license,  authorization or validation of, or filing,
         recording or  registration  with (except as have been  obtained or made
         prior to the  Execution  Date),  or exemption by, any  governmental  or
         public body or authority,  or any subdivision  thereof,  is required to
         authorize,  or is  required  in  connection  with,  (i) the  execution,
         delivery  and  performance  of  this  Guaranty  or (ii)  the  legality,
         validity, binding effect or enforceability of this Guaranty.

                  (e) There are no actions,  suits or proceedings pending or, to
         the best  knowledge of each  Guarantor,  threatened (i) with respect to
         any  Transaction  Document  or  (ii)  that  are  reasonably  likely  to
         materially  and adversely  affect the business,  operations,  property,
         assets,  condition  (financial  or  otherwise)  or  prospects  of  such
         Guarantor.

                  (f) All factual  information  (taken as a whole) heretofore or
         contemporaneously  furnished  by or on  behalf  of  each  Guarantor  in
         writing to the Agent or any Fund (including,  without  limitation,  all
         information  contained  herein) for purposes of or in  connection  with
         this Guaranty or any transaction  contemplated herein is, and all other
         such factual  information (taken as a whole) hereafter  furnished by or
         on behalf of such  Guarantor  in  writing to the Agent or any Fund will
         be, true and accurate in all material  respects on the date as of which
         such  information  is dated or certified and not incomplete by omitting
         to state any fact necessary to make such information (taken as a whole)
         not misleading at such time in light of the  circumstances  under which
         such information was provided.

                  (g) Each of Aura Ceramics and AuraSound is in compliance  with
         all applicable statutes,  regulations and orders of, and all applicable
         restrictions imposed by, all governmental bodies,  domestic or foreign,
         in respect of the  conduct of its  business  and the  ownership  of its
         property  (including  applicable  statutes,   regulations,  orders  and
         restrictions relating to environmental standards and controls),  except
         such  noncompliances  as would not, in the  aggregate,  have a material
         adverse effect on the business, operations, property, assets, condition
         (financial or otherwise) or prospects of such Guarantor.

                  (h)  The  Security  Agreement  creates,  as  security  for the
         Guaranteed  Obligations  hereunder  and  under  all  other  Transaction
         Documents,  a valid and  enforceable  security  interest  in all of the
         right,  title  and  interest  of the  relevant  Guarantor  as set forth
         thereunder in and to the Collateral  described  therein in favor of the
         Agent,  for the benefit of the Funds and, as to Aura  Ceramics and Aura
         Sound, of first priority on all of the Collateral superior to all Liens
         (subject to the priority  rights of holders of  Permitted  Liens of the
         types  described  in clauses  (c) and (i) of Section 4.1 of the Secured
         Notes and any extension,  renewal or replacement  thereof to the extent
         permitted by Section 4.1(k) of the Secured Notes);

                  (i) Each Guarantor is not an "investment  company"  within the
         meaning  of the  United  States  Investment  Company  Act of  1940,  as
         amended.

                  (j)  Each   Guarantor  is  not  a  "holding   company,"  or  a
         "subsidiary  company" of a "holding  company," or an  "affiliate"  of a
         "holding  company" or of a "subsidiary  company" of a "holding company"
         within the meaning of the United States Public Utility  Holding Company
         Act of 1935, as amended.

                  8. This Guaranty is a continuing  one and all  liabilities  to
which it  applies  or may apply  under the terms  hereof  shall be  conclusively
presumed  to have been  created in reliance  hereon.  No failure or delay on the
part of the  Agent or any  Fund in  exercising  any  right,  power or  privilege
hereunder  and no course of dealing  between the Company,  the  Guarantors,  the
Agent,  any Fund or the holder of any  Secured  Note  shall  operate as a waiver
thereof;  nor shall any  single  or  partial  exercise  of any  right,  power or
privilege  hereunder  preclude  any other or  further  exercise  thereof  or the
exercise of any other right, power or privilege. The rights, powers and remedies
herein expressly provided are cumulative and not exclusive of any rights, powers
or remedies  which the Agent,  any Fund or the holder of any Secured  Note would
otherwise  have.  No notice to or demand  on the  Guarantors  in any case  shall
entitle such Guarantor to any other further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Agent, any Fund or the
holder of any Secured Note to any other or further  action in any  circumstances
without notice or demand.

                  9. This Guaranty  shall be binding upon each Guarantor and its
respective  successors  and  assigns and shall inure to the benefit of the Agent
and the Funds and their respective successors and assigns.

                  10.  Neither  this  Guaranty nor any  provision  hereof may be
changed, waived, discharged or terminated except with the prior written approval
of the Agent.

                  11. The Guarantor acknowledges that an executed (or conformed)
copy of each of the  Secured  Notes has been  made  available  to its  principal
executive officers and such officers are familiar with the contents thereof.

                  12. In addition to any rights now or hereafter  granted  under
applicable  law or  otherwise,  and not by way of limitation of any such rights,
upon the  occurrence  of an  Event  of  Default  (which  has not  been  cured in
accordance  with the  terms of the  Secured  Notes),  the Agent and each Fund is
hereby authorized at any time or from time to time, without presentment, demand,
protest,  or other notice of any kind to the  Guarantors or to any other Person,
any such notice being hereby expressly waived, to set off and to appropriate and
apply any and all deposits  (general or special) and any other  Indebtedness  at
any time  held or owing by the  Agent or such  Fund to or for the  credit or the
account of the Guarantors  against and on account of the Guaranteed  Obligations
of the Guarantors to the Agent or such Fund under this Guaranty, irrespective of
whether or not the Agent or such Fund shall have made any demand  hereunder  and
although said  Guaranteed  Obligations,  or any of them,  shall be contingent or
unmatured.

                  13. All notices and other  communications  hereunder  shall be
made at the  addresses,  in the manner and with the effect  provided  in Section
10.1 of the Security Agreement.

                  14. If a claim is ever made  upon the  Agent,  any Fund or the
holder of any Secured  Note for  repayment  or recovery of any amount or amounts
received in payment or on account of any of the Guaranteed  Obligations  and any
of the  aforesaid  payees repays all or part of said amount by reason of (a) any
judgment,   decree  or  order  of  any  court  or  administrative   body  having
jurisdiction  over such payee or any of its  property or (b) any  settlement  or
compromise  of any such claim  effected  by such  payee  with any such  claimant
(including the Company),  then and in such event each Guarantor  agrees that any
such judgment, decree, order, settlement or compromise shall be binding upon it,
notwithstanding any revocation hereof or the cancellation of any Secured Note or
other  instrument  evidencing  any liability of the Company,  and each Guarantor
shall be and remain liable to the aforesaid  payees  hereunder for the amount so
repaid or  recovered  to the same extent as if such amount had never  originally
been received by any such payee.

                  15. Any  acknowledgment or new promise,  whether by payment of
principal  or  interest  or  otherwise  and  whether  by the  Company  or others
(including the  Guarantors),  with respect to any of the Guaranteed  Obligations
shall,  if the statute of  limitations  in favor of the  Guarantors  against the
Agent,  any Fund or the holder of any Note shall have commenced to run, toll the
running of such  statute of  limitations,  and if the period of such  statute of
limitations  shall  have  expired,  prevent  the  operation  of such  statute of
limitations.

                  16. This Guaranty and the rights and obligations of the Agent,
each of the Funds, the holders of any Secured Note and the Guarantors  hereunder
shall be  construed in  accordance  with and governed by the law of the State of
New York.  Any legal action or  proceeding  with respect to this Guaranty may be
brought in the  courts of the State of New York or of the United  States for the
Southern  District of New York, and, by execution and delivery of this Guaranty,
each  Guarantor  hereby  irrevocably  accepts  for  itself and in respect of its
property,  generally  and  unconditionally,  the  jurisdiction  of the aforesaid
courts.  Each Guarantor  hereby  irrevocably  designates,  appoints and empowers
Robinson,  Diamant & Brill,  1888  Century Park East,  Suite 1500,  Los Angeles,
California 90067, Attn. Lawrence A. Diamant, Esq. as its designee, appointee and
agent to receive,  accept and acknowledge for and on its behalf,  and in respect
of its  property,  service of any and all legal  process,  summons,  notices and
documents  which may be  served in any such  action  or  proceeding  under  this
Guaranty or the Security Agreement.  If for any reason such designee,  appointee
and agent shall cease to be available to act as such,  each Guarantor  agrees to
designate a new designee,  appointee and agent on the terms and for the purposes
of this provision  satisfactory to the Agent. Each Guarantor further irrevocably
consents to the service of process  out of any of the  aforementioned  courts in
any such action or proceeding by the mailing of copies  thereof by registered or
certified  mail,  postage  prepaid,  to such  Guarantor at its address set forth
opposite its signature below,  such service to become effective thirty (30) days
after such mailing. Nothing herein shall affect the right of the Agent, any Fund
or the holder of any Note to serve process in any other manner  permitted by law
or to commence legal  proceedings or otherwise proceed against each Guarantor in
any other  jurisdiction.  Each Guarantor hereby irrevocably waives any objection
which  it may  now or  hereafter  have  to the  laying  of  venue  of any of the
aforesaid  actions or  proceedings  arising  out of or in  connection  with this
Guaranty brought in the courts referred to above and hereby further  irrevocably
waives and  agrees not to plead or claim in any such court that any such  action
or  proceeding  brought  in any such court has been  brought in an  inconvenient
forum.

                  17. The  obligation of each  Guarantor to make payment in cash
of any Guaranteed Obligations due hereunder shall not be discharged or satisfied
by any tender, or any recovery  pursuant to any judgment,  which is expressed in
or converted into any currency other than cash, except to the extent such tender
or  recovery  shall  result in the actual  receipt by the Agent at its office on
behalf of the Funds or holders of the  Secured  Notes of the full amount of cash
expressed  to be  payable in respect  of any such  Guaranteed  Obligations.  The
obligation  of each  Guarantor  to make  payment in cash as  aforesaid  shall be
enforceable as an  alternative or additional  cause of action for the purpose of
recovery in cash of the amount,  if any, by which such actual receipt shall fall
short of the full amount of cash  expressed to be payable in respect of any such
Guaranteed Obligations, and shall not be affected by judgment being obtained for
any other sums due under this Guaranty.
