                  1. SECURITY FOR the SECURED OBLIGATIONS. This Agreement is for
the benefit of the Agent and the Funds to secure the payment and  performance of
the following  obligations  and  liabilities,  whether now existing or hereafter
arising (the "Secured Obligations"):

                  (i) the full and prompt  payment when due of all principal and
interest  under the  Secured  Notes,  the payment of all other  Obligations  and
liabilities  (including,  without limitation,  expenses,  fees,  indemnities and
interest thereon) of the Pledgor under, arising out of or in connection with the
Secured  Notes or any other  Transaction  Document and the due  performance  and
compliance by the Pledgor with the terms thereof;

                  (ii) any and all sums  advanced  by the  Agent or the Funds in
order to preserve  the  Collateral  or  preserve  the  security  interest in the
Collateral granted herein;

                  (iii) in the event of any  proceeding  for the  collection  or
enforcement of any  indebtedness,  obligations,  or  liabilities  referred to in
clause (i) above,  after an Event of Default  has  occurred  (which has not been
cured  in  accordance  with the  terms of the  Secured  Notes),  the  reasonable
expenses of retaking, holding, preparing for sale or lease, selling or otherwise
disposing or realizing on the Collateral, or of any exercise by the Agent of its
rights hereunder with respect thereto,  together with reasonable attorneys' fees
and court costs; and

                  (iv) all amounts paid by any Indemnitee (as defined in Section
8  hereof)  as to which  such  Indemnitee  has the right to  indemnification  or
reimbursement from the Pledgor under this Agreement.

                  2. DEFINITIONS. As used in this Agreement, the following terms
shall have the following meanings:

                  "Stock"  shall mean all the issued and  outstanding  shares of
capital  stock  of the  Subsidiaries  or any  other  subsidiary  of the  Pledgor
(excluding  New Com,  Inc.,  Aura  Realty,  Inc.  and MYS  Corporation),  now or
hereafter owned by the Pledgor.

                  All Stock pledged hereunder is hereinafter called the "Pledged
Stock," and the Pledged Stock, together with all proceeds thereof, including any
securities and moneys received and at the time held by the Pledgor hereunder, is
hereinafter called the "Collateral."

                  3.       PLEDGE OF STOCK, ETC.

                  3.1  Pledge.  To secure the  Secured  Obligations  and for the
purposes  set forth in Section 1, the Pledgor  (i) hereby  grants to the Agent a
security  interest in the  Collateral,  (ii)  hereby  pledges as security to the
Agent all Stock now or hereafter owned by the Pledgor, and (iii) hereby assigns,
transfers,  hypothecates,  mortgages,  charges  and sets  over to the  Agent (as
security)  all of the Pledgor's  right,  title and interest in and to such Stock
(and in and to the certificates or instruments evidencing such Stock).

                  3.2 Subsequently  Acquired Stock. If the Pledgor shall acquire
(by purchase,  stock dividend,  conversion or otherwise) any additional Stock at
any time or from time to time after the date  hereof,  the  Pledgor  agrees that
such  additional  Stock  shall be subject to the  security  interest  and pledge
created hereby,  without the need for the execution of any further  documents or
instruments,  and agrees to immediately  deposit such Stock as security with the
Agent and deliver to the Agent certificates therefor accompanied by stock powers
duly executed in blank by the Pledgor or such other  instruments  of transfer as
are  acceptable  to the Agent,  and,  upon request of the Agent,  will  promptly
thereafter deliver to the Agent a certificate executed by the Pledgor describing
such Stock and  certifying  that the same has been duly  pledged  with the Agent
hereunder.

                  3.3  Uncertificated  Stock.  Notwithstanding  anything  to the
contrary  contained  in Sections  3.1 and 3.2 above,  if any Stock  (whether now
owned or hereafter acquired) consists of an uncertificated security, the Pledgor
shall  promptly  notify the Agent  thereof and shall  promptly  take all actions
required to perfect the  security  interests of the Agent under  applicable  law
(including,  in any event,  under all  applicable  provisions  of the UCC of all
relevant jurisdictions).  The Pledgor further agrees to take such actions as the
Agent deems  necessary or desirable  to effect the  foregoing  and to permit the
Agent to  exercise  any of its  rights  and  remedies  hereunder,  and agrees to
provide an opinion of counsel in form and  substance  satisfactory  to the Agent
with respect to any such pledge of uncertificated Stock promptly upon request of
the Agent.

                  3.4 Voting, Etc., While No Event of Default.  Unless and until
an Event of Default has occurred  (which has not been cured in  accordance  with
the terms of the Secured  Notes),  the Pledgor shall be entitled to vote any and
all Pledged  Stock and to give  consents,  waivers or  ratifications  in respect
thereof,  provided  that  no  vote  shall  be cast  or any  consent,  waiver  or
ratification  given or any action taken which would  violate or be  inconsistent
with any of the terms of this Agreement,  or any other Transaction  Document, or
any other instrument or agreement referred to herein or therein,  or which could
reasonably be expected to have a Material Adverse Effect. All such rights of the
Pledgor to vote and to give consents, waivers and ratifications shall cease upon
the  occurrence  of an Event of Default  (which has not been cured in accordance
with the Secured Notes), and Section 5 hereof shall become applicable.

                  4.  DIVIDENDS  AND OTHER  DISTRIBUTIONS.  Unless and until the
occurrence of an Event of Default  (which has not been cured in accordance  with
the Secured Notes),  all cash dividends  payable in respect of the Pledged Stock
shall be paid to the Pledgor,  provided that all dividends payable in respect of
the Pledged Stock (except cash dividends paid to the Pledgor in accordance  with
Section  4.4(b)  of  the  Secured  Notes  as a  result  of  the  liquidation  or
disposition  of  Non-Core  Assets)  which are  determined  by the Agent,  in its
absolute  discretion,  to  represent  in  whole  or in  part  an  extraordinary,
liquidating  or other  distribution  in return of  capital  shall be paid to the
Agent and retained by it as part of the Collateral. Subject to Section 4.3(e) of
the Secured Notes, the Agent shall also be entitled to receive directly,  and to
retain as part of the Collateral:

                  (a) all other or  additional  stock or  securities or property
(other  than  cash) paid or  distributed  by way of  dividend  in respect of the
Pledged Stock;

                  (b) all  other or  additional  stock or  other  securities  or
property (including cash) paid or distributed in respect of the Pledged Stock by
way of stock-split, spin-off, split-up, reclassification,  combination of shares
or similar rearrangement; and

                  (c) all  other or  additional  stock or  other  securities  or
property  which  may be paid in  respect  of the  Collateral  by  reason  of any
consolidation,  merger, exchange of stock, conveyance of assets,  liquidation or
similar corporate reorganization.

                  5. REMEDIES IN CASE OF EVENT OF DEFAULT.  Upon the  occurrence
of an Event of Default (which has not been cured in accordance  with the Secured
Notes),  the Agent  shall be entitled  to  exercise  all the rights,  powers and
remedies  vested  in it  (whether  vested in it by this  Agreement  or any other
Transaction Document or by law) for the protection and enforcement of its rights
in  respect  of the  Collateral,  and  the  Agent  shall  be  entitled,  without
limitation, to exercise the following rights, which the Pledgor hereby agrees to
be commercially reasonable:

                  (a)  to  receive  (as  additional  Collateral  hereunder)  all
amounts payable in respect of the Collateral  otherwise  payable under Section 4
to the Pledgor; and

                  (b) at any  time  or  from  time  to  time  in a  commercially
reasonable manner to sell, assign and deliver, or grant options to purchase, all
or any part of the Collateral, or any interest therein, at any public or private
sale,  for  cash,  on  credit or for other  property,  for  immediate  or future
delivery without any assumption of credit risk, and for such price or prices and
on such terms as the Agent in its absolute  discretion may  determine,  provided
that at least ten (10) days' notice of the time and place of any such sale shall
be given to the Pledgor.  The Pledgor  hereby waives and releases to the fullest
extent  permitted by law any right or equity of  redemption  with respect to the
Collateral,  whether before or after sale hereunder,  and all rights, if any, of
marshaling the Collateral and any other security for the Secured  Obligations or
otherwise.  At any such sale,  unless prohibited by applicable law, the Agent or
any  Fund  on its  behalf  may  bid  for  and  purchase  all or any  part of the
Collateral so sold free from any such right or equity of  redemption.  The Agent
and the Funds shall not be liable for failure to collect or realize  upon any or
all of the  Collateral  or for any  delay in so doing  nor  shall any of them be
under any obligation to take any action whatsoever with regard thereto.

                  Notwithstanding  anything to the  contrary  contained  herein,
upon the  occurrence  of an  Event  of  Default  (which  has not  been  cured in
accordance with the Secured  Notes),  the Agent shall have the right to vote any
and all Pledged Stock and to give consents,  waivers or ratifications in respect
thereof in the Agent's sole discretion.

                  6. APPLICATION OF PROCEEDS.  All moneys collected by the Agent
upon any sale or other  disposition of the  Collateral,  together with all other
moneys received by the Agent  hereunder,  shall be applied to the payment of all
costs and  expenses  incurred  by the Agent in  connection  with such sale,  the
delivery of the  Collateral  or the  collection  of any such moneys  (including,
without  limitation,  attorneys'  fees and  expenses),  and the  balance of such
moneys  shall be held by the Agent and  applied  by it to  satisfy  the  Secured
Obligations.

                  7.  PURCHASERS OF COLLATERAL.  Upon any sale of the Collateral
by the Agent  hereunder  (whether by virtue of the power of sale herein granted,
pursuant  to  judicial  process or  otherwise),  the receipt of the Agent or the
officer  making the sale shall be a  sufficient  discharge  to the  purchaser or
purchasers of the Collateral so sold, and such purchaser or purchasers shall not
be obligated to see to the  application  of any part of the purchase  money paid
over  to the  Agent  or  such  officer  or be  answerable  in any  way  for  the
misapplication or nonapplication thereof.

                  8.       INDEMNITY.

                  8.1   Indemnification.   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
Pledgor agrees to indemnify,  reimburse and hold the Agent and each of the Funds
and its respective officers,  directors,  employees,  representatives and agents
(hereinafter in this Section 8.1 referred to  individually  as "Indemnitee"  and
collectively  as   "Indemnitees")   harmless  from  any  and  all   liabilities,
obligations,  losses, damages,  penalties,  claims, actions,  judgments,  suits,
costs,  expenses or  disbursements  (including  reasonable  attorneys'  fees and
expenses) (for the purposes of this Section 8.1, the foregoing are  collectively
called  "Expenses")  of  whatsoever  kind or  nature  which may be  imposed  on,
asserted against or incurred by any of the Indemnitees in any way relating to or
arising out of this Agreement,  any other Transaction  Document or the documents
executed in connection  herewith or therewith or in any other way connected with
the  administration  of the transactions  contemplated  hereby or thereby or the
enforcement of any of the terms of or the  preservation  of any rights under any
thereof,  or in any way relating to or arising out of the  ownership,  purchase,
delivery, control, acceptance, financing, possession, condition, sale, return or
other  disposition  or use of the  Collateral,  the violation of the laws of any
country,  state or other  governmental  body or unit,  any tort or any  contract
claim; provided that no Indemnitee shall be indemnified pursuant to this Section
8.1 for  Expenses  to the  extent  caused by the  gross  negligence  or  willful
misconduct of such  Indemnitee.  The Pledgor  agrees that upon written notice by
any Indemnitee of any assertion that could give rise to an Expense,  the Pledgor
shall assume full responsibility for the defense thereof. Each Indemnitee agrees
to use its best efforts to promptly  notify the Pledgor of any such assertion of
which such Indemnitee has knowledge.

                  8.2 Preservation of Collateral. Subject to Section 8.1 hereof,
the Pledgor  agrees to pay, or reimburse  the Agent for (if the Agent shall have
incurred fees, costs or expenses because the Pledgor shall have failed to comply
with its obligations  under this Agreement or any other  Transaction  Document),
any and all fees,  costs and  expenses  of whatever  kind or nature  incurred in
connection  with the  preservation  or  protection  of the Agent's Liens on, and
security interest in, the Collateral,  including,  without limitation,  all fees
and  taxes in  connection  with the  recording  or  filing  of  instruments  and
documents in public offices,  payment or discharge of any taxes or Liens upon or
in  respect  of the  Collateral  and all  other  fees,  costs  and  expenses  in
connection  with  protecting,  maintaining  or preserving the Collateral and the
Agent's interest therein,  whether through judicial proceedings or otherwise, or
in defending or prosecuting any actions,  suits or proceedings arising out of or
relating to the Collateral.

                  8.3 Pledgor's  Misrepresentation.  Subject to Sections 8.1 and
8.2  hereof,  the  Pledgor  agrees to pay,  indemnify  and hold each  Indemnitee
harmless from and against any expenses which such Indemnitee may suffer,  expend
or  incur in  consequence  of or  growing  out of any  misrepresentation  by the
Pledgor in this Agreement or any other Transaction  Document or in any statement
or writing  contemplated  by or made or delivered  pursuant to or in  connection
with this Agreement or any other Transaction Document.

                  8.4 Contribution. If and to the extent that the obligations of
the Pledgor under this Section 8 are unenforceable  for any reason,  the Pledgor
hereby agrees to make the maximum  contribution to the payment and  satisfaction
of such obligations which is permissible under applicable law.

                  8.5 Survival.  Any amounts paid by any  Indemnitee as to which
such  Indemnitee  has  the  right  to  reimbursement  shall  constitute  Secured
Obligations,  as the case  may be,  secured  by the  Collateral.  The  indemnity
obligations  of the Pledgor  contained in this Section 8 shall  continue in full
force and effect  notwithstanding  the full payment of the Secured Notes and all
of the other Secured Obligations and notwithstanding the discharge thereof.

                  9.       FURTHER ASSURANCES; POWER OF ATTORNEY.

                  9.1 Further  Acts.  The Pledgor  agrees that it will join with
the Agent in executing and, at its own expense, file and refile under the UCC of
all relevant  jurisdictions such financing statements,  continuation  statements
and other documents in such offices as the Agent may deem necessary or desirable
and  wherever  required or permitted by law in order to perfect and preserve the
Agent's security interests in the Collateral and hereby (i) authorizes the Agent
to file financing  statements and amendments thereto relative to all or any part
of the Collateral  without the signature of the Pledgor where  permitted by law,
(ii) irrevocably designates the Agent as its attorney-in-fact (which designation
shall be and shall be deemed to be coupled with an interest) to execute and file
on its behalf any and all  financing  statements,  continuation  statements  and
other documents  related  thereto,  and (iii) agrees to do such further acts and
things and to execute  and  deliver  to the Agent such  additional  conveyances,
assignments,  agreements and instruments as the Agent may reasonably  require or
deem advisable to carry into effect the purposes of this Agreement or to further
assure and confirm unto the Agent its rights, powers and remedies hereunder.

                  9.2 Power of Attorney.  The Pledgor hereby  appoints the Agent
as its  attorney-in-fact  (which  appointment shall be and shall be deemed to be
coupled with an  interest),  with full  authority in the place and stead of such
Pledgor and in the name of such  Pledgor or  otherwise,  from time to time after
the  occurrence  of an Event of Default  (which has not been cured in accordance
with the terms of the  Secured  Notes),  to take any action  and to execute  any
instrument  which  the Agent may  reasonably  deem  necessary  or  advisable  to
accomplish the purposes of this Agreement including, without limitation, to ask,
demand,  collect, sue for, recover,  compound,  receive and give acquittance and
receipts  for  moneys  due and to  become  due under or in  connection  with the
Collateral,  to receive,  endorse  and collect any drafts or other  instruments,
documents  and chattel  paper in  connection  with the  Collateral,  to file any
claims or take any action or institute any  proceedings  that the Agent may deem
to be necessary or desirable for the collection thereof or to enforce compliance
with the terms and  conditions  of this  Agreement,  and to make and execute all
conveyances,  assignments  and transfers of the Collateral sold pursuant to this
Agreement,  and the Pledgor hereby  ratifies and confirms all that the Agent, as
said  attorney-in-fact,  shall do by virtue  hereof.  Nevertheless,  the Pledgor
shall,  if so  requested  by the Agent,  ratify and confirm any sale or sales by
executing and delivering to the Agent,  or to such purchaser or purchasers,  all
such  instruments as may, in the reasonable  judgment of the Agent, be advisable
for the purposes of this Section 9.  Notwithstanding  the  foregoing,  except as
required by  applicable  law,  the Agent shall not be  obligated to exercise any
right or duty as  attorney-in-fact,  and shall have no duties to the  Pledgor in
connection therewith.

                  10. TRANSFER BY THE PLEDGOR.  Except as otherwise  provided in
Section 4 hereof,  the Pledgor will not sell or otherwise  dispose of, grant any
option with respect to, or create,  incur, assume or suffer to exist any Lien on
any portion of the  Collateral  (except the Liens created by this  Agreement and
other Permitted Liens).

                  11. REPRESENTATIONS,  WARRANTIES AND COVENANTS OF THE PLEDGOR.
The  Pledgor  represents  and  warrants  that:  (i) it is the legal,  record and
beneficial  owner of, and has good and marketable  title to, the Stock described
in  Section 2 hereof,  subject  to no Lien  (except  the Liens  created  by this
Agreement  and other  Permitted  Liens);  (ii) it has full power,  authority and
legal right to pledge all such Stock pursuant to this  Agreement;  (iii) all the
shares of such  Stock  have been duly and  validly  issued,  are fully  paid and
nonassessable;   (iv)  this  Agreement  creates  as  security  for  the  Secured
Obligations a valid and enforceable perfected Lien in favor of the Agent for the
benefit of the Funds 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); (v) no consent,  filing, recording or registration
is required to perfect the Lien purported to be created by this  Agreement;  and
(vi) each of the representations  and warranties  contained in Section 2 of each
Secured Note is true and correct.  The Pledgor covenants and agrees that it will
defend the Agent's right,  title and Lien in and to the  Collateral  against the
claims and demands of all Persons;  and the Pledgor covenants and agrees that it
will have  like  title to and right to  pledge  any other  property  at any time
hereafter pledged to the Agent as Collateral hereunder.

                  12. PLEDGOR'S  OBLIGATIONS  ABSOLUTE,  ETC. The obligations of
the Pledgor under this Agreement shall be 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:   (i)  any  renewal,
extension,  amendment  or  modification  of, or  addition  or  supplement  to or
deletion  from,  any of the  Transaction  Documents or any other  instrument  or
agreement  referred to therein,  or any  assignment  or transfer of any thereof;
(ii) any waiver,  consent,  extension,  indulgence  or other  action or inaction
under or in respect of any such instrument or agreement or this Agreement or any
exercise or  non-exercise of any right,  remedy,  power or privilege under or in
respect  of  this  Agreement  or  any  other  Transaction  Document;  (iii)  any
furnishing of any additional  security to the Agent or any acceptance thereof or
any sale, exchange, release, surrender or realization of or upon any security by
the Agent; or (iv) any invalidity,  irregularity or  unenforceability  of all or
part of the Secured Obligations or of any security therefor.

                  13.  PRIVATE  SALE,  ETC.  If at any time when the Agent shall
determine  to exercise  its right to sell all or any part of the  Pledged  Stock
pursuant to Section 5, such  Pledged  Stock or the part thereof to be sold shall
not, for any reason whatsoever,  be effectively  registered under the Securities
Act of 1933,  as then in  effect,  and the Agent may,  in its sole and  absolute
discretion,  sell such  Pledged  Stock or part  thereof by private  sale in such
manner and under such circumstances as the Agent may deem necessary or advisable
in order  that such sale may  legally be  effected  without  such  registration,
provided  that at least ten (10) days'  notice of the time and place of any such
sale shall be given to the  Pledgor.  Without  limiting  the  generality  of the
foregoing, in any such event the Agent, in its sole and absolute discretion, (i)
may  proceed  to make such  private  sale  notwithstanding  that a  registration
statement  for the purpose of  registering  such  Pledged  Stock or part thereof
shall have been filed under such Securities Act, (ii) may approach and negotiate
with a single possible purchaser to effect such sale and (iii) may restrict such
sale to a  purchaser  who will  represent  and  agree  that  such  purchaser  is
purchasing  for its own  account,  for  investment,  and not  with a view to the
distribution or sale of such Pledged Stock or any part thereof.

                  14.  TERMINATION;  RELEASE.  Upon the  payment  in full of all
Secured Obligations or the sale or other disposition of the Pledged Stock by the
Pledgor in accordance  with Section 4.3(d) of the Secured Notes,  this Agreement
shall terminate,  and the Agent, at the request and expense of the Pledgor, will
execute  and  deliver  to  the  Pledgor  a  proper   instrument  or  instruments
acknowledging the satisfaction and termination of this Agreement,  and will duly
assign,  transfer and deliver to the Pledgor  (without  recourse and without any
representation  or  warranty)  such  of  the  Pledged  Stock  as  may  be in the
possession of the Agent and has not theretofore  been sold or otherwise  applied
or released pursuant to this Agreement.

                  15.  NOTICES,   ETC.  All  notices  and  other  communications
hereunder  shall be made at the  addresses,  in the  manner  and with the effect
provided in Section 11.4 of the Secured Notes.

                  16.  MISCELLANEOUS.  This Agreement  shall be binding upon and
inure to the benefit of and be  enforceable  by the  respective  successors  and
assigns of the  parties  hereto;  provided,  however,  that the  Pledgor may not
assign or transfer any of its rights or obligations  hereunder without the prior
written consent of the Agent. This Agreement may be changed, waived,  discharged
or terminated only by an instrument in writing signed by the party against which
enforcement  of such change,  waiver,  discharge or  termination  is sought.  No
failure to exercise, and no delay in exercising, on the part of the Agent or any
of its agents, any right, power or privilege hereunder 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.  This  Agreement  shall be
construed in  accordance  with and governed by the law of the State of New York.
The  headings of the several  sections and  subsections  in this  Agreement  are

                              W I T N E S S E T H :

                  WHEREAS,  each of Infinity Investors Limited,  Glacier Capital

                  WHEREAS,  it is a condition to the Exchange that the Assignors
shall have executed and delivered this Agreement (this Agreement,  together with
the Secured  Notes,  the  Exchange  Agreement,  the  Guaranty,  the Stock Pledge
Agreement,  and all other documents,  certificates and instruments  executed and
delivered in connection with any of the foregoing, the "Transaction Documents");
and

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

                                    ARTICLE I

                               SECURITY INTERESTS

                  1.1      Grant of Security Interests.

                  (a) As  security  for the  prompt  and  complete  payment  and
performance when due of all of its Obligations,  each Assignor does hereby grant
to the Agent for the benefit of the Funds, a continuing security interest in all
of the right,  title and  interest of such  Assignor in, to and under all of the
following,  whether now existing or hereafter  from time to time  acquired:  (i)
each and every Receivable, (ii) all Contracts, together with all Contract Rights
arising  thereunder,  (iii) all Inventory,  (iv) all  Equipment,  (v) all Marks,
together  with the  registrations  and right to all  renewals  thereof,  and the
goodwill of the  business of such  Assignor  symbolized  by the Marks,  (vi) all
Patents and Copyrights and all reissues,  renewals or extensions thereof,  (vii)
all computer  programs of such  Assignor and all  intellectual  property  rights
therein and all other proprietary information of such Assignor,  including,  but
not limited to, Trade Secret  Rights,  (viii) all insurance  policies,  (ix) all
Permits,  (x) all other Goods, General  Intangibles,  Chattel Paper,  Documents,
Instruments and Investment  Property,  and (xi) all Proceeds and products of any
and all of the  foregoing  (all of the above  collectively,  the  "Collateral");
provided  however,  that the  Collateral  shall not  include  the  assets of the
Company or AuraSound  licensed to (A) Daewoo  Electronics Co., Ltd.  pursuant to
that  certain  License  Agreement  dated  August 19, 1996 (the  "Daewoo  License
Agreement")  only to the  extent  a  security  interest  in such  Collateral  is
prohibited  under the original  terms of the Daewoo License  Agreement,  and (B)
Speaker  Acquisition  Sub  pursuant  to  that  certain  Assignment  and  License
Agreement dated July 15, 1999 (the "Algo License  Agreement") only to the extent
a security interest in such Collateral is prohibited under the original terms of
the Algo License Agreement.

                  (b) The  security  interest of the Agent under this  Agreement
extends to all  Collateral  of the kind which is the  subject of this  Agreement
which the  Assignors  may  acquire at any time during the  continuation  of this
Agreement.

                  1.2 Power of Attorney.  Each Assignor  hereby  constitutes and
appoints the Agent its true and lawful  attorney,  irrevocably,  with full power
after  the  occurrence  of an  Event of  Default  (which  has not been  cured in
accordance  with the terms of the Secured Notes) in the name of such Assignor or
otherwise to act, require,  demand,  receive,  compound and give acquittance for
any and all moneys  and claims for moneys due or to become due to such  Assignor
under or  arising  out of the  Collateral,  to  endorse  any checks or orders in
connection  therewith and to file any claims or take any action or institute any
proceedings  which  the  Agent  may deem to be  necessary  or  advisable  in the
premises to protect and preserve the Collateral,  including, without limitation,
the  endorsement of any draft or order which may be payable to such Assignor and
the protection and prosecution of all rights  included in the Collateral,  which
appointment as attorney is coupled with an interest.

                                   ARTICLE II

                GENERAL REPRESENTATIONS, WARRANTIES AND COVENANTS

                  Each  Assignor  represents,   warrants  and  covenants,  which
representations,  warranties and covenants shall survive  execution and delivery
of this Agreement, as follows:

                  2.1  Necessary   Filings.   All  filings,   registrations  and
recordings necessary or appropriate to create, preserve, protect and perfect the
security interest granted by such Assignor to the Agent hereby in respect of all
the Collateral have been  accomplished and the security  interest granted to the
Agent pursuant to this  Agreement in and to the  Collateral  constitutes a valid
and enforceable  security  interest  therein superior and prior to the rights of
all other  Persons  therein  and  subject  to no other  Liens  (except  that the
Collateral  may be subject to Permitted  Liens) and the Agent is entitled to all
the rights, priorities and benefits afforded by the UCC or other relevant law as
enacted in any relevant jurisdiction to perfected security interests;  provided,
however,  the Assignor will not, and will not permit any of its Subsidiaries to,
nor  shall  any such  Person  allow  any other  Person  to,  file or record  any
assignment,  Lien,  security  interest,  encumbrance  or other  right,  title or
interest,  of any Person,  upon or with respect to any of the Proprietary Rights
of the Assignor  with the United States  Patent and  Trademark  Office.  Nothing
herein shall be deemed or  construed as an argument or admission  that the Liens
upon certain Proprietary Rights of the Assignor created pursuant to the Security
Documents  are  impaired  or  unperfected  nor shall  this  Agreement  impair or
prohibit the Company from  asserting that failure to record at the United States
Patent and Trademark  Office results in the Liens upon such  Proprietary  Rights
being unperfected.

                  2.2 No Liens.  Except as otherwise  provided  herein or in the
Stock Pledge  Agreement,  the Assignor is, and as to  Collateral  acquired by it
from time to time after the date hereof such  Assignor will be, the owner of all
Collateral free from any Lien,  security  interest,  encumbrance or other right,
title or interest of any Person (other than Permitted Liens),  and such Assignor
shall defend the Collateral against all claims and demands of all Persons at any
time claiming the same or any interest therein adverse to the Agent.

                  2.3 Other Financing  Statements.  As of the date hereof, there
is no financing  statement (or similar  statement or instrument of  registration
under the law of any jurisdiction)  covering or purporting to cover any interest
of any kind in the Collateral  (other than  Permitted  Liens) and so long as any
Secured  Note  remains  unpaid or any of the  Obligations  remain  unpaid,  such
Assignor  will not  execute or  authorize  to be filed in any public  office any
financing  statement (or similar  statement or instrument of registration  under
the law of any  jurisdiction) or statements  relating to the Collateral,  except
financing statements filed or to be filed in respect of the Permitted Liens (but
not including any filing with the United States Patent and Trademark Office) and
covering the security interests granted hereby by such Assignor.

                  2.4 Chief Executive  Office;  Records.  As of the date hereof,
the chief executive  office of each Assignor is located as set forth in Schedule
2.4 hereof.  The Assignor  shall give 30 days' prior written notice to the Agent
of its  intention  to move its  chief  executive  office  to  another  location;
provided, however, that any such change of location shall only be made after the
Agent  shall have  received  evidence  that such  Assignor  shall have taken all
actions, reasonably satisfactory to the Agent, subject to Section 2.1 hereof, to
maintain the  security  interest of the Agent in the  Collateral  intended to be
granted hereby at all times fully  perfected and in full force and effect in the
jurisdiction  where  the  chief  executive  office  of  such  Assignor  is to be
relocated.  The  originals  of all  documents  evidencing  all  relating  to the
Collateral  and the only original  books of account and records of such Assignor
relating  thereto  are,  and will  continue to be, kept at such chief  executive
office.  If for any reason any  Collateral or such other books and records shall
be located in any other location,  the Assignor shall,  with respect to such new
location, take, or shall have taken, all action,  reasonably satisfactory to the
Agent,  subject to Section 2.1 hereof,  to maintain the security interest of the
Agent in the  Collateral  intended  to be  granted  hereby  at all  times  fully
perfected  and in full  force and  effect in any event  within  the time  period
provided for the taking of such action required by applicable law.

                  2.5 Location of Bank Accounts,  Inventory and  Equipment.  All
bank accounts (including account numbers,  and name and address of the financial
institutions),  Inventory and Equipment  held on the date hereof by the Assignor
are  located  at one of the  locations  shown on Annex A  attached  hereto.  The
Assignor  agrees that all bank  accounts,  Inventory  and  Equipment now held or
subsequently  acquired  or  created  by it  shall  be  kept at (or  shall  be in
transport to or from) any one of the locations shown on Annex A hereto.  If, for
any reason,  any bank accounts,  Inventory or Equipment  shall be located in any
other  location,  the  Assignor  shall  immediately  notify the Agent and,  with
respect to such new location,  take, or shall have taken, all actions reasonably
satisfactory to the Agent to maintain the security  interest of the Agent in the
Collateral  intended to be granted  hereby at all times fully  perfected  and in
full  force and  effect in any event  within the time  period  provided  for the
taking of such action required by applicable law; provided however, that failure
of the  Assignors  to give  notice  to the Agent  herein  with  respect  to bank
accounts created after the Closing Date containing,  in the aggregate, less than
$100,000 shall not constitute an Event of Default under the Secured Notes.

                  2.6 Trade Names;  Change of Name.  As of the date hereof,  the
Assignor does not have or operate in any jurisdiction under, or in the preceding
12 months has not had or has not operated in any  jurisdiction  under, any trade
names, fictitious names or other names (including, without limitation, any names
of divisions or operations) except its legal name. The Assignor shall not change
its  legal  name or assume  or  operate  in any  jurisdiction  under any  trade,
fictitious  or other name except  those names listed  above  without  giving the
Agent 30 days' prior  written  notice  thereof,  which notice shall  contain the
proposed  names to be used and  jurisdictions  in which it  proposes  to operate
under such names.

                  2.7  Recourse.  This  Agreement is made with full  recourse to
each  Assignor  and  pursuant to and upon all the  warranties,  representations,
covenants,  and agreements on the part of such Assignor  contained  herein,  and
otherwise in writing in connection herewith or therewith.

                                   ARTICLE III

               SPECIAL PROVISIONS CONCERNING INVESTMENT PROPERTY;
                    RECEIVABLES; CONTRACT RIGHTS; INSTRUMENTS

                  3.1 Additional  Representations and Warranties. As of the time
when  each of its  Receivables  arises,  each  Assignor  shall be deemed to have
represented  and warranted  that such  Receivable,  and all records,  papers and
documents  relating thereto (if any) are genuine and, in all respects,  are what
they purport to be, and that all papers and documents (if any) relating  thereto
(i) will  represent  the genuine,  legal,  valid and binding  obligation  of the
account debtor evidencing indebtedness unpaid and owed by the respective account
debtor arising out of the  performance of labor or services or the sale or lease
and delivery of the merchandise  listed therein,  or both, (ii) will be the only
original writings evidencing and embodying such obligation of the account debtor
named therein (other than copies created for general accounting purposes), (iii)
will evidence true and valid  obligations,  enforceable in accordance with their
respective  terms  and (iv)  will be in  compliance  and will  conform  with all
applicable  federal,  state and local laws and  applicable  laws of any relevant
foreign jurisdiction.

                  3.2  Maintenance  of  Records.  Each  Assignor  will  keep and
maintain at its own cost and expense  satisfactory  and complete  records of the
Collateral,  and such  Assignor  will make the same  available  to the Agent for
inspection, at any and all reasonable times upon reasonable prior notice to such
Assignor. If requested by the Agent after an Event of Default has occurred which
has not been cured in accordance with the Secured Notes, each Assignor shall, at
its own cost and expense,  deliver all tangible  evidence of its Receivables and
Contract  Rights  (including,   without  limitation,  copies  of  all  documents
evidencing the  Receivables and all Contracts) and such books and records to the
Agent or to its representatives  (copies of which evidence and books and records
may be retained by such Assignor).  If the Agent so directs, each Assignor shall
legend, in form and manner reasonably satisfactory to the Agent, the Receivables
and  Contracts,  as  well as  books,  records  and  documents  of such  Assignor
evidencing or pertaining to such  Receivables  and Contracts with an appropriate
reference to the fact that the Agent has a security interest in such Receivables
and Contracts.
                  3.3  Modification  of  Terms;  etc.  Each  Assignor  shall not
rescind or cancel any  indebtedness  evidenced  by any  Receivable  or under any
Contract,  or  modify  any term  thereof  or make any  adjustment  with  respect
thereto,  or extend or renew the same,  or  compromise  or settle  any  material
dispute,  claim,  suit  or  legal  proceeding  relating  thereto,  or  sell  any
Receivable or Contract,  or interest therein,  without the prior written consent
of the Agent, except as permitted by Section 3.4 hereof.

                  3.4  Collection.  Each Assignor  shall  endeavor in accordance
with its customary  business practices to cause to be collected from the account
debtor named in each of its  Receivables  or obligor under any Contract,  as and
when due (including,  without  limitation,  amounts which are  delinquent,  such
amounts to be collected in accordance with generally  accepted lawful collection
procedures)  any and all amounts owing under or on account of such Receivable or
Contract,  and apply  forthwith upon receipt  thereof all such amounts as are so
collected to the outstanding  balance of such Receivable or under such Contract,
except  that,  so long as no Event of Default has  occurred  (which has not been
cured in accordance with the terms of the Secured Notes) in respect of which the
Agent has  given  notice  that this  exception  is no  longer  applicable,  such
Assignor may allow in the ordinary  course of business as adjustments to amounts
owing under its  Receivables  and  Contracts  (i) an extension or renewal of the
time or times of payment,  or settlement for less than the total unpaid balance,
which such Assignor finds appropriate in accordance with sound business judgment
and (ii) a refund or credit due as a result of returned  or damaged  merchandise
or improperly performed services.  The reasonable costs and expenses (including,
without  limitation,  attorneys'  fees) of collection,  whether  incurred by any
Assignor or the Agent,  shall be borne by the Assignor or the applicable account
debtor.

                  3.5  Instruments.   If  any  Assignor  owns  or  acquires  any
Instrument or Investment  Property,  such  Assignor  will,  within ten (10) days
thereof,  notify the Agent and deliver such Instrument or Investment Property to
the Agent  appropriately  endorsed to the order of the Agent as further security
hereunder,  provided  that an Assignor may transfer an Instrument to the Company
whereupon the Company shall deliver  immediately such Instrument to the Agent in
accordance with this Section 3.5.

                  3.6 Further  Actions.  Each Assignor will, at its own expense,
make, execute, endorse,  acknowledge, file and/or deliver to the Agent from time
to  time  such  vouchers,   invoices,   schedules,   confirmatory   assignments,
conveyances,  financing statements,  transfer endorsements,  powers of attorney,
certificates,  reports and other assurances or instruments and take such further
steps relating to its Receivables,  Contracts, Instruments,  Investment Property
and other property or rights covered by the security interest hereby granted, as
the  Agent  may  reasonably  require  to give  effect  to the  purposes  of this
Agreement.

                                   ARTICLE IV

                    SPECIAL PROVISIONS CONCERNING TRADEMARKS

                  4.1 Additional  Representations and Warranties.  Each Assignor
represents and warrants that it is the true and lawful owner of all right, title
and  interest  in  and  to  the  United  States  Patent  and  Trademark   Office
registrations,  and applications for registrations, of the Marks listed in Annex
B  attached  hereto  and that  Annex B lists all the  United  States  Patent and
Trademark  Office,  or the  equivalent  office  thereof in any foreign  country,
registrations  and  applications  for  registrations,  of the  Marks  that  such
Assignor now owns or uses in connection with its business and which are material
in the  conduct  of such  Assignor's  business.  Each  Assignor  represents  and
warrants that except with respect to those  licensed marks set forth in Annex B,
it owns,  is licensed to use or otherwise has the right to use all Marks that it
uses.  Each Assignor  further  warrants that it is aware of no third party claim
that any aspect of such Assignor's present or contemplated  business  operations
infringes  or will  infringe  any  Mark.  Except  as set  forth on Annex B, each
Assignor  represents  and  warrants  that it is the true and lawful  owner of or
otherwise  has the right to use all  trademark  registrations  and  applications
listed in Annex C hereto and that said registrations are valid, subsisting, have
not been canceled and that such Assignor is not aware of any  third-party  claim
that any of said  registrations or applications for registration with respect to
a Mark is invalid or unenforceable or is not aware that there is any reason that
any of said  registrations or applications  for  registration  with respect to a
Mark is invalid or unenforceable.

                  4.2 Licenses and Assignments.  Each Assignor hereby agrees not
to divest itself of any right under a Mark other than in the ordinary  course of
business absent prior written approval of the Agent.

                  4.3  Infringements.   Each  Assignor  agrees,   promptly  upon
learning thereof, to notify the Agent in writing of the name and address of, and
to furnish such pertinent information that may be available with respect to, any
party who may be  infringing  or otherwise  violating in any of such  Assignor's
rights in and to any Mark,  or with  respect  to any  party  claiming  that such
Assignor's  use of any Mark  violates  any  property  right of that party.  Each
Assignor further agrees to prosecute  diligently any Person  infringing any Mark
owned by such  Assignor in a manner  consistent  with its past  practice  and in
accordance with reasonable business practices.  Notwithstanding  anything herein
to the contrary,  such Assignor may exercise its business judgment  hereunder in
respect  of any Mark used in  connection  with the  Company's  Non-Core  Assets;
provided  however,  that such Assignor  shall give timely notice  thereof to the
Agent, and that the Agent and/or the Funds (if such Assignor declines to protect
such Marks) may take such actions as  reasonably  necessary at their own expense
to protect such Marks.

                  4.4  Preservation  of Marks.  Each  Assignor  agrees to use or
license  the use of its Marks in  interstate  commerce  during the time in which
this Agreement is in effect,  sufficiently  to preserve such Marks as trademarks
or service marks  registered under the laws of the United States or the relevant
foreign  jurisdiction.  Notwithstanding  anything  herein to the contrary,  such
Assignor may exercise  its  business  judgment  hereunder in respect of any Mark
used in connection with such Assignor's Non-Core Assets;  provided however, that
such Assignor shall give prompt notice thereof to the Agent,  and that the Agent
and/or the Funds (if such Assignor declines to protect such Marks) may take such
actions as reasonably necessary at their own expense to protect such Marks.

                  4.5 Maintenance of  Registration.  Each Assignor shall, at its
own expense,  diligently  process all documents  required to maintain  trademark
registrations,  including but not limited to affidavits of use and  applications
for renewals of registration in the United States Patent and Trademark Office or
equivalent  governmental agency in any foreign jurisdiction for all of its Marks
(excluding  unregistered  Marks),  and shall pay all fees and  disbursements  in
connection therewith,  and shall not abandon any such filing of affidavit of use
or any such application of renewal prior to the exhaustion of all administrative
and judicial  remedies without prior written consent of the Agent (which consent
shall not be  unreasonably  withheld).  Notwithstanding  anything  herein to the
contrary,  such Assignor may exercise its business judgment hereunder in respect
of any Mark used in connection with such Assignor's  Non-Core  Assets;  provided
however,  that such Assignor shall give prompt notice thereof to the Agent,  and
that the Agent  and/or the Funds (if such  Assignor  declines  to  protect  such
Marks) may take such  actions as  reasonably  necessary  at their own expense to
protect such Marks.

                  4.6 Future Registered  Marks. If any Mark registration  issues
hereafter  to any  Assignor  as a result  of any  application  now or  hereafter
pending  before the United  States  Patent and  Trademark  Office or  equivalent
governmental  agency in any foreign  jurisdiction,  such Assignor shall,  within
thirty  (30)  days  of  receipt  of  such  certificate,  deliver  a copy of such
certificate,  and a grant of security in such Mark to the Agent,  confirming the
grant thereof hereunder, the form of such confirmatory grant to be substantially
the same as the form hereof.

                  4.7  Remedies.  If an Event of Default  shall occur (which has
not been cured in  accordance  with the terms of the Secured  Notes),  the Agent
may, by written notice to the Assignors, exercise any or all remedies under this
Agreement, the UCC or any other applicable law.

                                    ARTICLE V

                          SPECIAL PROVISIONS CONCERNING
                   TRADE SECRET RIGHTS, PATENTS AND COPYRIGHTS

                  5.1 Additional  Representations and Warranties.  Each Assignor
represents and warrants that it is the true and lawful owner of all right, title
and  interest in and to (i) all Trade  Secret  Rights,  (ii) the Patents of such
Assignor listed in Annex C attached hereto and that said Patents  constitute all
the patents and  applications  for patents that such Assignor now owns and which
are  material in the conduct of its business  and (iii) the  Copyrights  of such
Assignor listed in Annex D attached  hereto and that said Copyrights  constitute
all the registered copyrights and applications for copyright  registrations that
such  Assignor now owns and which are  material in the conduct of its  business.
Each Assignor  represents  and warrants that it owns all Patents and  Copyrights
that it owns, uses or practices under. Each Assignor further warrants that it is
aware of no third  party  claim  that any aspect of such  Assignor's  present or
contemplated  business operations infringes or will infringe any material patent
or any material copyright or that such Assignor has misappropriated any material
Trade Secret Rights.

                  5.2 Licenses and Assignments.  Each Assignor hereby agrees not
to divest itself of any right,  title or interest  under any Patent or Copyright
(other than those  Patents and  Copyrights  with  respect to Non-Core  Assets in
accordance with the Secured Notes) absent prior written approval of the Agent.

                  5.3  Infringements.   Each  Assignor  agrees,   promptly  upon
learning thereof, to furnish the Agent in writing with all pertinent information
available to such Assignor with respect to any  infringement  or other violation
of such  Assignor's  rights in any Patent or  Copyright,  or with respect to any
claim that the practice of any Patent or the use of any  Copyright  violates any
property right of a third party or with respect to any  misappropriation  of any
material  Trade  Secret Right or any claim that the practice of any Trade Secret
Right violates any property right of a third party. Each Assignor further agrees
to prosecute  diligently any Person  infringing any Patent or Copyright owned by
such   Assignor  or  any  Person   misappropriating   any  Trade  Secret  Right.
Notwithstanding  anything herein to the contrary, such Assignor may exercise its
business  judgment  hereunder  in  respect of any  Patent or  Copyright  used in
connection with such Assignor's  Non-Core Assets;  provided  however,  that such
Assignor  shall give  prompt  notice  thereof  to the Agent,  and that the Agent
and/or  the  Funds  (if such  Assignor  declines  to  protect  such  Patents  or
Copyrights)  may take such actions as reasonably  necessary at their own expense
to protect such Patents or Copyrights.

                  5.4 Maintenance of Patents or Copyrights.  At its own expense,
each Assignor  shall make timely payment of all  post-issuance  fees required to
maintain  in  force   rights   under  each  of  its   Patents  and   Copyrights.
Notwithstanding  anything herein to the contrary, such Assignor may exercise its
business  judgment  hereunder  in  respect of any  Patent or  Copyright  used in
connection with such Assignor's  Non-Core Assets;  provided  however,  that such
Assignor  shall give  prompt  notice  thereof  to the Agent,  and that the Agent
and/or  the  Funds  (if such  Assignor  declines  to  protect  such  Patents  or
Copyrights)  may take such actions as reasonably  necessary at their own expense
to protect such Patents or Copyrights.

                  5.5 Prosecution of Patent or Copyright Application. At its own
expense,  each Assignor  shall  diligently  prosecute all  applications  for (i)
Patents listed on Annex C hereto and (ii)  Copyrights  listed on Annex D hereto,
and, in each case, shall not abandon any such application prior to exhaustion of
all administrative  and judicial  remedies,  absent written consent of the Agent
(which consent shall not be  unreasonably  withheld).  Notwithstanding  anything
herein to the  contrary,  such  Assignor  may  exercise  its  business  judgment
hereunder in respect of any Patent or  Copyright  used in  connection  with such
Assignor's  Non-Core  Assets;  provided  however,  that such Assignor shall give
prompt notice thereof to the Agent, and that the Agent and/or the Funds (if such
Assignor  declines to protect such Patents or Copyrights)  may take such actions
as  reasonably  necessary  at their own  expense  to  protect  such  Patents  or
Copyrights.

                  5.6 Other Patents and  Copyrights.  Within thirty (30) days of
the acquisition or issuance of a Patent or Copyright registration,  or of filing
of an application  for a Patent or Copyright  registration,  each Assignor shall
deliver to the Agent a copy of said  Patent or  Copyright  registration,  as the
case may be, with a grant of security  as to such  Patent or  Copyright,  as the
case  may  be,  confirming  the  grant  thereof  hereunder,  the  form  of  such
confirmatory grant to be substantially the same as the form hereof.

                  5.7  Remedies.  If an Event of Default  shall occur (which has
not been cured in accordance with the Secured  Notes),  the Agent may by written
notice to an Assignor take any or all remedies under this Agreement,  the UCC or
any other applicable law.

                                   ARTICLE VI

                      PROVISIONS CONCERNING ALL COLLATERAL

                  6.1 No  Impairment.  Each Assignor  shall do nothing to impair
the rights of the Agent in the Collateral except as set forth in the Transaction
Documents and subject to Section 2.1 hereof.

                  6.2 Financing Statements.  Each Assignor agrees to execute and
deliver to the Agent such financing statements, in form acceptable to the Agent,
as the Agent  may from  time to time  reasonably  request  or as are  reasonably
necessary or desirable in the  reasonable  opinion of the Agent to establish and
maintain a valid,  enforceable and perfected security interest in the Collateral
as provided herein  (subject to Section 2.1 hereof and Permitted  Liens) and the
other rights and security  contemplated hereby all in accordance with the UCC as
enacted in any and all relevant  jurisdictions  or any other  relevant law. Each
Assignor  will pay any  applicable  filing fees,  recordation  taxes and related
expenses.  Each Assignor hereby  authorizes the Agent to file any such financing
statements without the signature of such Assignor where permitted by law.

                                   ARTICLE VII

                  REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT

                  7.1 Remedies;  Obtaining  the  Collateral  Upon Default.  Each
Assignor agrees that, if any Event of Default shall have occurred (which has not
been cured in accordance with the terms of the Secured Notes), then and in every
such case,  subject to any  mandatory  requirements  of  applicable  law then in
effect,  the Agent,  in addition to any rights now or hereafter  existing  under
applicable law, shall have all rights as a secured creditor under the UCC in all
relevant jurisdictions or any other applicable law and may, without limitation:

                  (i) personally,  or by agents or attorneys,  immediately  take
         possession of the  Collateral or any part thereof  and/or any documents
         or instruments relating thereto, from such Assignor or any other Person
         who then has  possession  of any part  thereof  with or, to the  extent
         permitted by applicable law,  without notice or process of law, and for
         that purpose may, in accordance with applicable  laws,  enter upon such
         Assignor's  premises  where any of the Collateral is located and remove
         the same and use in connection  with such removal any and all services,
         supplies, aids and other facilities of such Assignor;

                  (ii)  instruct  the  obligor  or  obligors  on any  agreement,
         instrument or other  obligation  (including,  without  limitation,  the
         Contracts)  constituting  or  relating  to the  Collateral  to make any
         payment required by the terms of such instrument or agreement  directly
         to the Agent;

                  (iii)  sell,  assign or  otherwise  liquidate,  or direct such
         Assignor  to sell,  assign or  otherwise  liquidate,  any or all of the
         Collateral or any part thereof,  and take possession of the proceeds of
         any such sale or liquidation; and

                  (iv) take  possession  of the  Collateral  or any part thereof
         and/or any documents or instruments relating thereto, by directing such
         Assignor  in writing  to deliver  the same to the Agent at any place or
         places reasonably designated by the Agent, in which event such Assignor
         shall at its own expense:

                           (A) forthwith cause the same to be moved to the place
                  or places so  designated  by the Agent and there  delivered to
                  the Agent,

                           (B) store and keep any Collateral so delivered to the
                  Agent at such place or places  pending  further  action by the
                  Agent as provided in Section 7.2, and

                           (C) while the Collateral shall be so stored and kept,
                  provide  such  guards  and  maintenance  services  as shall be
                  necessary  to protect  the same and to preserve  and  maintain
                  them in good condition,

it being understood that such Assignor's obligation so to deliver the Collateral
is of the essence of this Agreement and that, accordingly, upon application to a
court of equity  having  jurisdiction,  the Agent  shall be entitled to a decree
requiring specific performance by such Assignor of said obligation.

                  7.2  Remedies;   Disposition  of  the  Collateral.   Upon  the
occurrence of an Event of Default  (which has not been cured in accordance  with
the terms of the Secured Notes),  any Collateral  repossessed by the Agent under
or  pursuant  to  Section  7.1  and  any  other  Collateral  whether  or  not so
repossessed by the Agent, may be sold, assigned, leased or otherwise disposed of
under one or more  contracts  or as an  entirety,  and without the  necessity of
gathering at the place of sale the  property to be sold,  and in general in such
manner,  at such time or times,  at such  place or  places  and on  commercially
reasonable  terms.  Any of the  Collateral  may be  sold,  leased  or  otherwise
disposed of, in the  condition in which the same existed when taken by the Agent
or after any commercially  reasonable  overhaul or repair.  Any such disposition
which shall be a private  sale or other  private  proceedings  permitted by such
requirements  shall be made upon not less than ten (10) days' written  notice to
such Assignor  specifying  the time at which such  disposition is to be made and
the intended sale price or other consideration  therefor,  and shall be subject,
for the ten (10) days  after the  giving  of such  notice,  to the right of such
Assignor or any nominee of such Assignor to acquire the Collateral involved at a
price or for such other  consideration at least equal to the intended sale price
or other  consideration  so  specified.  Any such  disposition  which shall be a
public sale permitted by such requirements  shall be made upon not less than ten
(10) days' written notice to such Assignor specifying the time and place of such
sale and, in the absence of applicable  requirements  of law, shall be by public
auction  (which  may,  at the  Agent's  option,  be subject to  reserve),  after
publication  of notice of such auction not less than ten (10) days prior thereto
in two  newspapers in general  circulation  in Los Angeles,  California.  To the
extent  permitted  by any such  requirement  of law,  the Agent,  the Funds,  or
certain  of them,  may bid for and  become  the  purchaser  (by  bidding  in the
Obligations  or  otherwise) of the  Collateral or any item thereof,  offered for
sale in accordance  with this Section  without  accountability  to such Assignor
(except to the extent of surplus money received as provided in Section 7.4). If,
under  mandatory  requirements of applicable law, the Agent shall be required to
make disposition of the Collateral within a period of time which does not permit
the giving of notice to such Assignor as hereinabove  specified,  the Agent need
give such  Assignor  only  such  notice of  disposition  as shall be  reasonably
practicable  in view of such  mandatory  requirements  of  applicable  law. Each
Assignor  agrees to do or cause to be done all such other acts and things as may
be reasonably  necessary to make such sale or sales of all or any portion of the
Collateral valid and binding and in compliance with any and all applicable laws,
regulations,  orders,  writs,  injunctions,  decrees  or  awards  of any and all
courts,  arbitrations  or governmental  instrumentalities,  domestic or foreign,
having jurisdiction over any such sale or sales, all at such Assignor's expense.

7.3 Waiver.  If the Agent  seeks to exercise  its  remedies  hereunder  and take
possession of any of the  Collateral  by court  process,  EACH  ASSIGNOR  HEREBY
IRREVOCABLY  WAIVES (A) ANY BOND AND ANY  SURETY OR  SECURITY  RELATING  THERETO
REQUIRED BY LAW AS AN INCIDENT TO SUCH POSSESSION, (B) ANY DEMAND FOR POSSESSION
PRIOR TO THE  COMMENCEMENT OF ANY SUIT OR ACTION TO RECOVER  POSSESSION  THEREOF
AND (C) ANY REQUIREMENT THAT THE AGENT RETAIN POSSESSION OF, AND NOT DISPOSE OF,
ANY SUCH COLLATERAL UNTIL AFTER TRIAL OR FINAL JUDGMENT.

         THE  FAILURE OF THE AGENT AT ANY TIME OR TIMES TO REQUIRE  ASSIGNOR  TO
STRICTLY  COMPLY  WITH ANY OF THE  PROVISIONS  OF THIS  AGREEMENT  OR ANY  OTHER
TRANSACTION DOCUMENT SHALL NOT WAIVE OR DIMINISH ANY RIGHT OF THE AGENT LATER TO
DEMAND AND RECEIVE STRICT COMPLIANCE THEREWITH.  ANY WAIVER OF ANY DEFAULT SHALL
NOT WAIVE OR AFFECT ANY OTHER DEFAULT, WHETHER PRIOR OR SUBSEQUENT,  AND WHETHER
OR  NOT  SIMILAR.  NONE  OF THE  PROVISIONS  OF  THIS  AGREEMENT  OR  ANY  OTHER
TRANSACTION DOCUMENT SHALL BE DEEMED TO HAVE BEEN WAIVED BY ANY ACT OR KNOWLEDGE
OF THE AGENT OR ITS AGENTS OR EMPLOYEES,  BUT ONLY BY A SPECIFIC  WRITTEN WAIVER
SIGNED BY AN AUTHORIZED OFFICER OF THE AGENT AND DELIVERED TO THE ASSIGNOR. EACH
ASSIGNOR  WAIVES  DEMAND,  PROTEST,  NOTICE OF PROTEST  AND NOTICE OF DEFAULT OR
DISHONOR,  NOTICE OF PAYMENT AND NONPAYMENT,  RELEASE,  COMPROMISE,  SETTLEMENT,
EXTENSION  OR RENEWAL OF ANY  COMMERCIAL  PAPER,  INSTRUMENT,  ACCOUNT,  GENERAL
INTANGIBLE, DOCUMENT, CHATTEL PAPER, INVESTMENT PROPERTY OR GUARANTY AT ANY TIME
HELD BY THE AGENT OR THE FUNDS ON WHICH ASSIGNOR IS OR MAY IN ANY WAY BE LIABLE,
AND NOTICE OF ANY ACTION TAKEN BY THE AGENT,  UNLESS EXPRESSLY  REQUIRED BY THIS
AGREEMENT, AND NOTICE OF ACCEPTANCE THEREOF.

                  7.4      Application of Proceeds.

                  (a) All moneys  collected  by the Agent upon any sale or other
disposition of the  Collateral,  together with all other moneys  received by the
Agent hereunder, shall be applied as follows:

                  (i) to the payment of any and all expenses and fees (including
         reasonable attorneys' fees) incurred by the Agent in obtaining,  taking
         possession of, or removing, insuring,  repairing, storing and disposing
         of  Collateral  and  any and  all  amounts  incurred  by the  Agent  in
         connection therewith;

                  (ii) next,  any surplus  then  remaining to the payment of the
Obligations under the Secured Notes in the following order of priority:

     (A)      all accrued and unpaid interest on overdue principal and interest;

     (B)      all other accrued and unpaid interest; and

     (C)      all outstanding principal; and

                  (iii) next,  any surplus then  remaining to the payment of any
other Obligations under this Agreement or any other Transaction Document.

                  (b) It is understood that each Assignor shall remain liable to
the extent of any deficiency between (i) the amount of the Obligations for which
it is liable that are  satisfied  with proceeds of the  Collateral  and (ii) the
aggregate outstanding amount of such Obligations.

                  7.5  Remedies  Cumulative.  Each and  every  right,  power and
remedy  hereby  specifically  given to the Agent  shall be in  addition to every
other right,  power and remedy  specifically  given under this  Agreement or the
other Transaction  Documents or now or hereafter existing at law or in equity or
by statute,  and each and every  right,  power and remedy  whether  specifically
herein  given  or  otherwise  existing  may be  exercised  from  time to time or
simultaneously  and as often and in such order as may be deemed expedient by the
Agent. All such rights, powers and remedies shall be cumulative and the exercise
or the beginning of exercise of one shall not be deemed a waiver of the right to
exercise any other or others.  No delay or omission of the Agent in the exercise
of any such  right,  power or remedy and no renewal or  extension  of any of the
Obligations shall impair any such right,  power or remedy nor shall be construed
to be a waiver of any Event of Default or an acquiescence  therein. In the event
that the Agent shall bring any suit to enforce any of its rights  hereunder  and
shall be entitled to judgment, then in such suit the Agent may recover expenses,
including  attorneys'  fees,  and the amounts  thereof shall be included in such
judgment.

                  7.6  Discontinuance  of  Proceedings.  In case the Agent shall
have instituted any proceeding to enforce any right,  power or remedy under this
Agreement by foreclosure,  sale,  entry or otherwise,  and such proceeding shall
have been discontinued or abandoned for any reason or shall have been determined
adversely to the Agent,  then and in every such case, the  Assignors,  the Agent
and each holder of any of the  Obligations  shall be  restored  to their  former
positions and rights  hereunder  with respect to the  Collateral  subject to the
security  interest  created under this Agreement,  and all rights,  remedies and
powers of the Agent shall continue as if no such  proceeding had been instituted
(except  to the  extent  of a  determination  adverse  to the  Agent  in  such a
proceeding).

                                  ARTICLE VIII

                                    INDEMNITY

                  8.1      Indemnity.

                  (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 hereof, each Assignor agrees to indemnify, reimburse and
hold the Agent, each Fund and their respective  successors,  permitted  assigns,
directors,  officers,  Affiliates,  employees,  attorneys,  agents and  servants
(hereinafter in this Section 8.1 referred to individually as  "Indemnitee,"  and
collectively  as   "Indemnitees")   harmless  from  any  and  all   liabilities,
obligations,  losses,  damages,  penalties,  claims,  demands,  actions,  suits,
judgments and any and all reasonable  costs and expenses,  including  reasonable
attorneys'  fees and  expenses  (for  the  purposes  of this  Section  8.1,  the
foregoing are  collectively  called  "Expenses")  of whatsoever  kind and nature
imposed on,  asserted  against or incurred by any of the  Indemnitees in any way
relating to or arising out of this Agreement,  any other Transaction Document or
the documents executed in connection  herewith and therewith or in any other way
connected with the enforcement of any of the terms of, or the  preservation  of,
any rights hereunder or thereunder,  or in any way relating to or arising out of
the manufacture,  ownership,  ordering, purchase, delivery, control, acceptance,
lease,  financing,  possession,  operation,  condition,  sale,  return  or other
disposition, or use of the Collateral (including,  without limitation, latent or
other defects,  whether or not discoverable),  or the violation by such Assignor
of the laws of any country,  state or other  governmental body or unit, any tort
(including,  without limitation, claims arising or imposed under the doctrine of
strict  liability,  or for or on account of injury to or the death of any Person
(including any Indemnitee),  or property  damage),  or contract claim;  provided
that no  Indemnitee  shall be  indemnified  pursuant to this Section  8.1(a) for
Expenses to the extent caused by the gross  negligence or willful  misconduct of
such Indemnitee. Each Assignor agrees that upon written notice by any Indemnitee
of  the  assertion  of  such  an  Expense,   such  Assignor  shall  assume  full
responsibility   for  the  defense  thereof  if  such  Assignor  would  have  an
indemnification  obligation under this Section 8.1(a).  The Indemnitee agrees to
use its best efforts to promptly  notify such Assignor of any such  assertion of
which such Indemnitee has knowledge.

                  (b) Without  limiting the application of Section 8.1(a),  each
Assignor agrees,  jointly and severally,  to pay, or reimburse the Agent for (if
the Agent shall have  incurred  fees,  costs or expenses  because such  Assignor
shall have failed to comply with its  obligations  under this  Agreement  or any
other Transaction Document),  any and all reasonable fees, costs and expenses of
whatever kind or nature incurred in connection  with the creation,  preservation
or protection of the Agent's Liens on, and security  interest in, the Collateral
granted  hereunder,  including,  without  limitation,  all  fees  and  taxes  in
connection  with the recording or filing of instruments  and documents in public
offices,  payment or  discharge  of any taxes or Liens upon or in respect of the
Collateral and all other  reasonable fees, costs and expenses in connection with
protecting,  maintaining or preserving  the Collateral and the Agent's  interest
therein,  whether through judicial proceedings or otherwise,  or in defending or
prosecuting any actions,  suits or proceedings arising out of or relating to the
Collateral.

                  (c) Without limiting the application of Section 8.1(a) or (b),
each Assignor agrees to pay,  indemnify and hold each  Indemnitee  harmless from
and against any loss,  costs,  damages and expenses  which such  Indemnitee  may
suffer, expend or incur in consequence of any misrepresentation by such Assignor
in this  Agreement,  or in any statement or writing  contemplated  by or made or
delivered pursuant to or in connection with this Agreement.

                  (d) If and to the extent that the  obligations  of an Assignor
under this Section 8.1 are  unenforceable  for any reason,  such Assignor hereby
agrees to make the maximum  contribution to the payment and satisfaction of such
obligations which is permissible under applicable law.

                  8.2 Indemnity Obligations Secured by Collateral; Survival. Any
amounts  paid by any  Indemnitee  as to which such  Indemnitee  has the right to
reimbursement  under this Agreement shall constitute  Obligations secured by the
Collateral.  The indemnity  obligations of the Company contained in this Article
VIII shall continue in full force and effect notwithstanding the full payment of

invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

obligations of the parties  hereunder  shall be construed in accordance with and

Agreement or any other Transaction Document with respect to the Collateral,  and
the Agent  and the Funds  shall not have any  obligations  or  liabilities  with
respect to any  Collateral by reason of or arising out of this  Agreement or any
other  Transaction  Document,  nor shall the Agent or the Funds be  required  or
obligated  in any manner to perform or  fulfill  any of the  obligations  of the
