referred to in the  preceding  sentence  unless all filings have been made under
the Uniform  Commercial  Code or  otherwise  that are  required in order for the
Collateral Agent to continue at all times following such change to have a valid,
legal and perfected first priority  security  interest in all the Collateral for
which perfection or priority, as the case may be, may be established by any such
filings.  Each Grantor  agrees  promptly to notify the  Collateral  Agent if any
material  portion of the Collateral  owned or held by such Grantor is damaged or
destroyed.

                  (b)  Each  Grantor  agrees  to  maintain,  at its own cost and
expense, such complete and accurate records with respect to the Collateral owned
by it as is consistent  with its current  practices and 

                                       7


in accordance  with such prudent and standard  practices used in industries that
are the same as or similar to those in which such Grantor is engaged, but in any
event to  include  complete  accounting  records  indicating  all  payments  and
proceeds received with respect to any part of the Collateral,  and, at such time
or times as the Collateral Agent may reasonably request, promptly to prepare and
deliver to the Collateral  Agent a duly certified  schedule or schedules in form
and detail satisfactory to the Collateral Agent showing the identity, amount and
location of any and all Collateral.

                  SECTION 4.02. Periodic  Certification.  Each year, at the time
of delivery of annual financial  statements with respect to the preceding fiscal
year  pursuant  to Section  5.04 of the Credit  Agreement,  the  Borrower  shall
deliver to the Collateral  Agent a certificate  executed by a Financial  Officer
and the chief legal  officer of the Borrower (a) setting  forth the  information
required pursuant to Section 2 of the Perfection  Certificate or confirming that
there has been no change in such information  since the date of such certificate
or the date of the most recent  certificate  delivered  pursuant to Section 4.02
and (b)  certifying  that  all  Uniform  Commercial  Code  financing  statements
(including  fixture  filings,  as  applicable)  or  other  appropriate  filings,
recordings  or   registrations,   including  all  refilings,   rerecordings  and
reregistrations,  containing a description of the Collateral  have been filed of
record  in each  governmental,  municipal  or other  appropriate  office in each
jurisdiction  identified pursuant to clause (a) above to the extent necessary to
protect  and  perfect  the  Security  Interest  for a period of not less than 18
months after the date of such certificate  (except as noted therein with respect
to any continuation statements to be filed within such period). Each certificate
delivered pursuant to this Section 4.02 shall identify in the format of Schedule
II, III, IV or V, as  applicable,  all  Intellectual  Property of any Grantor in
existence  on the  date  thereof  and  not  then  listed  on such  Schedules  or
previously so identified to the Collateral Agent.

                  SECTION 4.03.  Protection of Security.  Each Grantor shall, at
its own cost and expense,  take any and all actions necessary to defend title to
the  Collateral  against all persons and to defend the Security  Interest of the
Collateral Agent in the Collateral and the priority thereof against any Lien not
expressly permitted pursuant to Section 6.02 of the Credit Agreement.

                  SECTION 4.04. Further Assurances.  Each Grantor agrees, at its
own  expense,  to execute,  acknowledge,  deliver and cause to be duly filed all
such  further  instruments  and  documents  and  take all  such  actions  as the
Collateral  Agent may from time to time  request  to  better  assure,  preserve,
protect and perfect the Security  Interest  and the rights and remedies  created
hereby,  including the payment of any fees and taxes required in connection with
the  execution  and  delivery of this  Agreement,  the  granting of the Security
Interest and the filing of any financing statements  (including fixture filings)
or other  documents in connection  herewith or therewith.  If any amount payable
under or in connection with any of the Collateral  shall be or become  evidenced
by any promissory  note or other  instrument,  such note or instrument  shall be
immediately  pledged and delivered to the Collateral  Agent,  duly endorsed in a
manner satisfactory to the Collateral Agent.

                  Without limiting the generality of the foregoing, each Grantor
hereby  authorizes  the  Collateral  Agent,  with prompt  notice  thereof to the
Grantors, to supplement this Agreement by supplementing  Schedule II, III, IV or
V hereto or adding  additional  schedules  hereto to  specifically  identify any
asset or item that may constitute Copyrights,  Licenses,  Patents or Trademarks;
provided,  however, that any Grantor shall have the right, exercisable within 10
days  after  it has  been  notified  by the  Collateral  Agent  of the  specific
identification of such Collateral,  to advise the Collateral Agent in writing of
any  inaccuracy  of the  representations  and  warranties  made by such  Grantor
hereunder with respect to such Collateral.  Each Grantor agrees that it will use
its best  efforts to take such  action as 

                                       8


shall be necessary in order that all  representations  and warranties  hereunder
shall be true and correct with respect to such  Collateral  within 30 days after
the  date  it  has  been  notified  by the  Collateral  Agent  of  the  specific
identification of such Collateral.

                  Each Grantor further agrees that if any  authorization of such
Grantor  excluded  from the  Collateral  pursuant  to the final  sentence of the
definition  of  "License"  could be  included  therein  with the  receipt of any
approval of, or the taking of any action by, any  Governmental  Authority,  such
Grantor  shall  use its best  efforts  to  obtain  such  approval  or  action as
expeditiously as possible.

                  SECTION 4.05.  Inspection  and  Verification.  The  Collateral
Agent and such persons as the Collateral  Agent may reasonably  designate  shall
have  the  right,  at the  Grantors'  own  cost  and  expense,  to  inspect  the
Collateral,  all records  related  thereto (and to make extracts and copies from
such records) and the premises upon which any of the  Collateral is located,  to
discuss  the  Grantors'  affairs  with the  officers of the  Grantors  and their
independent  accountants and to verify under reasonable procedures the validity,
amount, quality,  quantity,  value, condition and status of, or any other matter
relating to, the Collateral, including, in the case of Accounts or Collateral in
the possession of any third person,  by contacting  Account Debtors or the third
person possessing such Collateral for the purpose of making such a verification.
The Collateral  Agent shall have the absolute right to share any  information it
gains from such  inspection  or  verification  with any Secured  Party (it being
understood that any such information shall be deemed to be "Information" subject
to the provisions of Section 9.16 of the Credit Agreement).

                  SECTION  4.06.  Taxes;   Encumbrances.   At  its  option,  the
Collateral  Agent may  discharge  past due taxes,  assessments,  charges,  fees,
Liens,  security interests or other encumbrances at any time levied or placed on
the  Collateral  and not  permitted  pursuant  to  Section  6.02  of the  Credit
Agreement, and may pay for the maintenance and preservation of the Collateral to
the extent any Grantor  fails to do so as required  by the Credit  Agreement  or
this Agreement,  and each Grantor jointly and severally  agrees to reimburse the
Collateral  Agent on demand for any payment made or any expense  incurred by the
Collateral  Agent pursuant to the foregoing  authorization;  provided,  however,
that nothing in this  Section 4.06  shall be interpreted as excusing any Grantor
from the performance  of, or imposing any obligation on the Collateral  Agent or
any Secured  Party to cure or perform,  any  covenants or other  promises of any
Grantor with  respect to taxes,  assessments,  charges,  fees,  liens,  security
interests or other  encumbrances  and  maintenance as set forth herein or in the
other Loan Documents.

                  SECTION 4.07.  Assignment of Security Interest. If at any time
any Grantor shall take a security  interest in any property of an Account Debtor
or any other  person to secure  payment  and  performance  of an  Account,  such
Grantor shall promptly  assign such security  interest to the Collateral  Agent.
Such assignment need not be filed of public record unless  necessary to continue
the  perfected  status  of  the  security  interest  against  creditors  of  and
transferees  from the  Account  Debtor or other  person  granting  the  security
interest.

                  SECTION 4.08.  Continuing  Obligations  of the Grantors.  Each
Grantor  shall  remain  liable to observe  and perform  all the  conditions  and
obligations to be observed and performed by it under each contract, agreement or
instrument  relating to the  Collateral,  all in  accordance  with the terms and
conditions  thereof,  and each Grantor jointly and severally agrees to indemnify
and hold harmless the Collateral  Agent and the Secured Parties from and against
any and all liability for such performance.

                  SECTION 4.09. Use and  Disposition of Collateral.  None of the
Grantors shall make 

                                       9


or permit to be made an assignment, pledge or hypothecation of the Collateral or
shall  grant any other Lien in respect of the  Collateral,  except as  expressly
permitted by Section 6.02 of the Credit  Agreement.  None of the Grantors  shall
make or permit to be made any transfer of the  Collateral and each Grantor shall
remain at all times in  possession  of the  Collateral  owned by it, except that
(a) Inventory  may be sold in the ordinary course of business and (b) unless and
until the  Collateral  Agent shall notify the Grantors  that an Event of Default
shall have occurred and be continuing  and that during the  continuance  thereof
the  Grantors  shall not sell,  convey,  lease,  assign,  transfer or  otherwise
dispose of any  Collateral  (which  notice may be given by telephone if promptly
confirmed in writing), the Grantors may use and dispose of the Collateral in any
lawful manner not inconsistent with the provisions of this Agreement, the Credit
Agreement or any other Loan  Document.  Without  limiting the  generality of the
foregoing,  each Grantor  agrees that it shall not permit any Inventory to be in
the possession or control of any warehouseman, bailee, agent or processor at any
time  unless  such  warehouseman,  bailee,  agent or  processor  shall have been
notified of the  Security  Interest and shall have agreed in writing to hold the
Inventory  subject  to  the  Security  Interest  and  the  instructions  of  the
Collateral  Agent and to waive and release  any Lien held by it with  respect to
such Inventory, whether arising by operation of law or otherwise.

                  SECTION 4.10. Limitation on Modification of Accounts.  None of
the Grantors will, without the Collateral  Agent's prior written consent,  grant
any  extension  of the  time  of  payment  of any  of the  Accounts  Receivable,
compromise,  compound or settle the same for less than the full amount  thereof,
release,  wholly or partly,  any person liable for the payment  thereof or allow
any credit or  discount  whatsoever  thereon,  other than  extensions,  credits,
discounts,  compromises or settlements granted or made in the ordinary course of
business and consistent  with its current  practices and in accordance with such
prudent  and  standard  practices  used in  industries  that  are the same as or
similar to those in which such Grantor is engaged.

                  SECTION 4.11.  Insurance.  The Grantors, at their own expense,
shall  maintain or cause to be maintained  insurance  covering  physical loss or
damage to the Inventory  and  Equipment in  accordance  with Section 5.02 of the
Credit Agreement.  Each Grantor irrevocably makes,  constitutes and appoints the
Collateral  Agent  (and all  officers,  employees  or agents  designated  by the
Collateral Agent) as such Grantor's true and lawful agent (and attorney-in-fact)
for the  purpose,  during the  continuance  of an Event of  Default,  of making,
settling  and  adjusting  claims in  respect of  Collateral  under  policies  of
insurance, endorsing the name of such Grantor on any check, draft, instrument or
other item of payment for the  proceeds of such  policies of  insurance  and for
making all determinations and decisions with respect thereto.  In the event that
any  Grantor at any time or times  shall fail to obtain or  maintain  any of the
policies  of  insurance  required  hereby or to pay any premium in whole or part
relating  thereto,  the Collateral  Agent may,  without waiving or releasing any
obligation  or liability of the Grantors  hereunder or any Event of Default,  in
its sole discretion, obtain and maintain such policies of insurance and pay such
premium and take any other actions with respect thereto as the Collateral  Agent
deems  advisable.  All sums disbursed by the Collateral Agent in connection with
this Section 4.11, including reasonable  attorneys' fees, court costs,  expenses
and other  charges  relating  thereto,  shall be payable,  upon  demand,  by the
Grantors to the  Collateral  Agent and shall be additional  Obligations  secured
hereby.

                  SECTION 4.12.  Legend.  Each Grantor shall legend, in form and
manner  satisfactory to the Collateral  Agent,  its Accounts  Receivable and its
books,   records  and  documents   evidencing  or  pertaining  thereto  with  an
appropriate  reference  to the fact  that  such  Accounts  Receivable  have been
assigned to the Collateral Agent for the benefit of the Secured Parties and that
the Collateral Agent has a security interest therein.

                                       10


                  SECTION  4.13.  Covenants  Regarding  Patent,   Trademark  and
Copyright  Collateral.  (a) Each  Grantor  agrees that it will not,  nor will it
permit any of its licensees  to, do any act, or omit to do any act,  whereby any
Patent  which is material to the conduct of such  Grantor's  business may become
invalidated  or  dedicated to the public,  and agrees that it shall  continue to
mark any  products  covered  by a Patent  with the  relevant  patent  number  as
necessary  and  sufficient  to establish  and preserve its maximum  rights under
applicable patent laws.

                  (b) Each Grantor  (either  itself or through its  licensees or
its  sublicensees)  will,  for each  Trademark  material  to the conduct of such
Grantor's  business,  (i)  maintain  such  Trademark in full force free from any
claim of  abandonment  or invalidity  for non-use,  (ii) maintain the quality of
products and services offered under such Trademark, (iii) display such Trademark
with  notice of Federal  or foreign  registration  to the extent  necessary  and
sufficient to establish and preserve its maximum rights under applicable law and
(iv)  not  knowingly  use or  knowingly  permit  the  use of such  Trademark  in
violation of any third party rights.

                  (c) Each Grantor  (either itself or through  licensees)  will,
for each work covered by a material Copyright,  continue to publish,  reproduce,
display,  adopt and distribute  the work with  appropriate  copyright  notice as
necessary  and  sufficient  to establish  and preserve its maximum  rights under
applicable copyright laws.

                  (d) Each Grantor shall notify the Collateral Agent immediately
if it knows or has  reason  to know  that any  Patent,  Trademark  or  Copyright
material to the conduct of its business may become abandoned,  lost or dedicated
to the public,  or of any adverse  determination  or development  (including the
institution of, or any such  determination  or development in, any proceeding in
the United States Patent and Trademark Office, United States Copyright Office or
any court or similar office of any country)  regarding such Grantor's  ownership
of any Patent,  Trademark or  Copyright,  its right to register the same,  or to
keep and maintain the same.

                  (e) In no event shall any  Grantor,  either  itself or through
any agent, employee,  licensee or designee,  file an application for any Patent,
Trademark or Copyright (or for the  registration  of any Trademark or Copyright)
with the United  States  Patent and Trademark  Office,  United States  Copyright
Office or any office or agency in any political subdivision of the United States
or in any other country or any political subdivision thereof, unless it promptly
informs  the  Collateral  Agent,  and,  upon  request of the  Collateral  Agent,
executes and delivers any and all agreements,  instruments, documents and papers
as the Collateral Agent may request to evidence the Collateral  Agent's security
interest  in such  Patent,  Trademark  or  Copyright,  and each  Grantor  hereby
appoints the Collateral Agent as its  attorney-in-fact  to execute and file such
writings for the  foregoing  purposes,  all acts of such  attorney  being hereby
ratified  and  confirmed;  such  power,  being  coupled  with  an  interest,  is
irrevocable.

                  (f) Each  Grantor  will  take  all  necessary  steps  that are
consistent  with the practice in any proceeding  before the United States Patent
and Trademark Office,  United States Copyright Office or any office or agency in
any  political  subdivision  of the United States or in any other country or any
political  subdivision thereof, to maintain and pursue each material application
relating  to the  Patents,  Trademarks  and/or  Copyrights  (and to  obtain  the
relevant  grant or  registration)  and to maintain  each issued  Patent and each
registration of the Trademarks and Copyrights that is material to the conduct of
any Grantor's  business,  including  timely filings of applications for renewal,
affidavits of use,  affidavits of  incontestability  and payment of  maintenance
fees, and, if consistent with good business  judgment,  to initiate  opposition,
interference and cancellation proceedings against third parties.

                                       11


                  (g) In the event that any Grantor  has reason to believe  that
any Collateral  consisting of a Patent,  Trademark or Copyright  material to the
conduct  of any  Grantor's  business  has  been  or is  about  to be  infringed,
misappropriated  or diluted by a third party, such Grantor promptly shall notify
the  Collateral  Agent and shall,  if consistent  with good  business  judgment,
promptly sue for infringement,  misappropriation  or dilution and to recover any
and all damages for such infringement,  misappropriation  or dilution,  and take
such other actions as are appropriate  under the  circumstances  to protect such
Collateral.

                  (h) Upon and during the  continuance  of an Event of  Default,
each  Grantor  shall use its best  efforts to obtain all  requisite  consents or
approvals by the licensor of each Copyright License, Patent License or Trademark
License to effect  the  assignment  of all of such  Grantor's  right,  title and
interest thereunder to the Collateral Agent or its designee.


                                    ARTICLE V

                                Power of Attorney



                  Each Grantor  irrevocably makes,  constitutes and appoints the
Collateral  Agent  (and all  officers,  employees  or agents  designated  by the
Collateral Agent) as such Grantor's true and lawful agent and  attorney-in-fact,
and in such capacity the  Collateral  Agent shall have the right,  with power of
substitution  for each Grantor and in each Grantor's name or otherwise,  for the
use and  benefit  of the  Collateral  Agent and the  Secured  Parties,  upon the
occurrence and during the  continuance  of an Event of Default  (a) to  receive,
endorse, assign and/or deliver any and all notes,  acceptances,  checks, drafts,
money orders or other  evidences of payment  relating to the  Collateral  or any
part thereof; (b) to demand,  collect,  receive payment of, give receipt for and
give  discharges and releases of all or any of the  Collateral;  (c) to sign the
name of any  Grantor  on any  invoice or bill of lading  relating  to any of the
Collateral;  (d) to send  verifications  of Accounts  Receivable  to any Account
Debtor;  (e) to commence and prosecute any and all suits, actions or proceedings
at law or in  equity  in any  court of  competent  jurisdiction  to  collect  or
otherwise  realize on all or any of the  Collateral  or to enforce any rights in
respect of any Collateral; (f) to settle, compromise, compound, adjust or defend
any  actions,  suits or  proceedings  relating to all or any of the  Collateral;
(g) to  notify,  or to require  any Grantor to notify,  Account  Debtors to make
payment  directly to the  Collateral  Agent;  and  (h) subject  to the mandatory
requirements of applicable law, to use, sell, assign, transfer, pledge, make any
agreement with respect to or otherwise  deal with all or any of the  Collateral,
and to do all other acts and things  necessary to carry out the purposes of this
Agreement,  as fully and  completely  as though  the  Collateral  Agent were the
absolute  owner of the  Collateral  for all  purposes,  including  assigning any
contract  to  any  Subsidiary  or  any  other  person  at any  time  during  the
continuance  of any Event of Default;  provided,  however,  that nothing  herein
contained shall be construed as requiring or obligating the Collateral  Agent or
any Secured Party to make any commitment or to make any inquiry as to the nature
or  sufficiency of any payment  received by the Collateral  Agent or any Secured
Party,  or to present or file any claim or  notice,  or to take any action  with
respect to the Collateral or any part thereof or the moneys due or to become due
in respect  thereof or any  property  covered  thereby,  and no action  taken or
omitted to be taken by the Collateral Agent or any Secured Party with respect to
the Collateral or any part thereof shall give rise to any defense,  counterclaim
or  offset  in favor  of any  Grantor  or to any  claim or  action  against  the
Collateral  Agent or any Secured  Party.  It is  understood  and agreed that the
appointment of 

                                       12


the Collateral Agent as the agent and  attorney-in-fact  of the Grantors for the
purposes  set forth above is coupled with an interest  and is  irrevocable.  The
provisions of this Article V shall in no event relieve any Grantor of any of its
obligations  hereunder  or under any other  Loan  Document  with  respect to the
Collateral or any part thereof or impose any obligation on the Collateral  Agent
or any Secured  Party to proceed in any  particular  manner with  respect to the
Collateral  or any  part  thereof,  or in any  way  limit  the  exercise  by the
Collateral Agent or any Secured Party of any other or further right which it may
have on the date of this Agreement or hereafter,  whether  hereunder,  under any
other Loan Document, by law or otherwise.


                                   ARTICLE VI

                                    Remedies

                  SECTION 6.01.  Remedies upon Default.  Upon the occurrence and
during the  continuance  of an Event of Default,  each Grantor agrees to deliver
each item of Collateral to the Collateral Agent on demand, and it is agreed that
the  Collateral  Agent shall have the right to take any of or all the  following
actions at the same or  different  times:  (a) with  respect  to any  Collateral
consisting of Intellectual  Property,  on demand, to cause the Security Interest
to  become  an  assignment,  transfer  and  conveyance  of any  of or  all  such
Collateral by the applicable  Grantors to the Collateral Agent, or to license or
sublicense,  whether general,  special or otherwise, and whether on an exclusive
or  non-exclusive  basis,  any such  Collateral  throughout the universe on such
terms and conditions and in such manner as the Collateral  Agent shall determine
(other than in  violation of any  then-existing  licensing  arrangements  to the
extent that waivers  cannot be obtained),  and (b) with or without legal process
and with or without prior notice or demand for  performance,  to take possession
of the Collateral and without liability for trespass to enter any premises where
the  Collateral  may be  located  for the  purpose  of taking  possession  of or
removing the Collateral and, generally,  to exercise any and all rights afforded
to a secured party under the Uniform  Commercial  Code or other  applicable law.
Without  limiting the generality of the foregoing,  each Grantor agrees that the
Collateral Agent shall have the right, subject to the mandatory  requirements of
applicable  law,  to  sell  or  otherwise  dispose  of all or  any  part  of the
Collateral,  at  public  or  private  sale or at any  broker's  board  or on any
securities  exchange,  for cash,  upon  credit  or for  future  delivery  as the
Collateral  Agent  shall  deem  appropriate.   The  Collateral  Agent  shall  be
authorized  at any such sale (if it deems it advisable to do so) to restrict the
prospective  bidders or purchasers to persons who will  represent and agree that
they are  purchasing the Collateral for their own account for investment and not
with a view to the  distribution or sale thereof,  and upon  consummation of any
such sale the  Collateral  Agent  shall have the right to assign,  transfer  and
deliver to the purchaser or purchasers thereof the Collateral so sold. Each such
purchaser at any such sale shall hold the property  sold  absolutely,  free from
any claim or right on the part of any Grantor,  and each Grantor  hereby  waives
(to the extent  permitted by law) all rights of  redemption,  stay and appraisal
which such  Grantor now has or may at any time in the future have under any rule
of law or statute now existing or hereafter enacted.

                  The Collateral Agent shall give the Grantors  10 days' written
notice  (which each Grantor  agrees is  reasonable  notice within the meaning of
Section 9-504(3) of the Uniform Commercial Code as in effect in the State of New
York  or its  equivalent  in  other  jurisdictions)  of the  Collateral  Agent's
intention to make any sale of Collateral.  Such notice,  in the case of a public
sale, shall state the time and place for such sale and, in the case of a sale at
a broker's board or on a securities exchange,  shall state the board or exchange
at which such sale is to be made and the day on which the Collateral, 

                                       13


or portion  thereof,  will first be offered for sale at such board or  exchange.
Any such  public  sale  shall  be held at such  time or  times  within  ordinary
business hours and at such place or places as the  Collateral  Agent may fix and
state in the notice (if any) of such sale. At any such sale, the Collateral,  or
portion thereof, to be sold may be sold in one lot as an entirety or in separate
parcels,  as the  Collateral  Agent  may (in its sole and  absolute  discretion)
determine.  The Collateral  Agent shall not be obligated to make any sale of any
Collateral  if it shall  determine  not to do so,  regardless  of the fact  that
notice of sale of such Collateral  shall have been given.  The Collateral  Agent
may, without notice or publication,  adjourn any public or private sale or cause
the same to be adjourned from time to time by announcement at the time and place
fixed for sale, and such sale may,  without further notice,  be made at the time
and  place to which  the same was so  adjourned.  In case any sale of all or any
part of the Collateral is made on credit or for future delivery,  the Collateral
so sold may be retained by the Collateral  Agent until the sale price is paid by
the purchaser or purchasers  thereof,  but the Collateral  Agent shall not incur
any liability in case any such purchaser or purchasers shall fail to take up and
pay for the Collateral so sold and, in case of any such failure, such Collateral
may be sold again upon like notice.  At any public (or, to the extent  permitted
by law,  private) sale made pursuant to this Section,  any Secured Party may bid
for or  purchase,  free (to the  extent  permitted  by law)  from  any  right of
redemption,  stay,  valuation  or appraisal on the part of any Grantor (all said
rights being also hereby  waived and  released to the extent  permitted by law),
the  Collateral  or any part  thereof  offered for sale and may make  payment on
account  thereof by using any claim then due and payable to such  Secured  Party
from any Grantor as a credit against the purchase price,  and such Secured Party
may, upon  compliance with the terms of sale,  hold,  retain and dispose of such
property without further  accountability to any Grantor  therefor.  For purposes
hereof,  a written  agreement to purchase the Collateral or any portion  thereof
shall be treated as a sale thereof;  the Collateral Agent shall be free to carry
out such sale pursuant to such agreement and no Grantor shall be entitled to the
return of the Collateral or any portion thereof subject thereto, notwithstanding
the fact  that  after the  Collateral  Agent  shall  have  entered  into such an
agreement  all Events of Default  shall have been  remedied and the  Obligations
paid in full. As an alternative to exercising the power of sale herein conferred
upon it, the Collateral Agent may proceed by a suit or suits at law or in equity
to foreclose this  Agreement and to sell the  Collateral or any portion  thereof
pursuant  to a  judgment  or  decree  of a  court  or  courts  having  competent
jurisdiction or pursuant to a proceeding by a court-appointed receiver.

                  SECTION 6.02.  Application of Proceeds.  The Collateral  Agent
shall apply the proceeds of any collection or sale of the Collateral, as well as
any Collateral consisting of cash, as follows:

                  FIRST,  to the payment of all costs and  expenses  incurred by
         the  Administrative  Agent or the Collateral  Agent (in its capacity as
         such  hereunder or under any other Loan  Document) in  connection  with
         such  collection or sale or otherwise in connection with this Agreement
         or any of the  Obligations,  including all court costs and the fees and
         expenses of its agents and legal counsel, the repayment of all advances
         made by the Collateral Agent hereunder or under any other Loan Document
         on behalf of any Grantor  and any other  costs or expenses  incurred in
         connection with the exercise of any right or remedy  hereunder or under
         any other Loan Document;

                  SECOND, to the payment in full of the Obligations (the amounts
         so applied to be  distributed  among the  Secured  Parties  pro rata in
         accordance with the amounts of the Obligations owed to them on the date
         of any such distribution); and

                  THIRD, to the Grantors,  their successors or assigns,  or as a
         court of competent 

                                       14


jurisdiction may otherwise direct.

The  Collateral  Agent  shall  have  absolute  discretion  as  to  the  time  of
application  of any such  proceeds,  moneys or balances in accordance  with this
Agreement.  Upon any sale of the Collateral by the Collateral  Agent  (including
pursuant to a power of sale granted by statute or under a judicial  proceeding),
the receipt of the Collateral Agent or of 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 Collateral  Agent
or such officer or be answerable in any way for the misapplication thereof.

                  SECTION 6.03. Grant of License to Use  Intellectual  Property.
For the purpose of enabling the Collateral Agent to exercise rights and remedies
under  this  Article  at such time as the  Collateral  Agent  shall be  lawfully
entitled to exercise such rights and remedies, each Grantor hereby grants to the
Collateral  Agent an irrevocable,  non-exclusive  license  (exercisable  without
payment of royalty or other  compensation  to the  Grantors) to use,  license or
sub-license any of the Collateral  consisting of Intellectual Property now owned
or hereafter acquired by such Grantor, and wherever the same may be located, and
including  in such  license  reasonable  access to all media in which any of the
licensed  items may be  recorded  or stored  and to all  computer  software  and
programs used for the compilation or printout  thereof.  The use of such license
by the  Collateral  Agent shall be  exercised,  at the option of the  Collateral
Agent,  upon the occurrence and during the  continuation of an Event of Default;
provided that any license,  sub-license or other transaction entered into by the
Collateral  Agent in  accordance  herewith  shall be binding  upon the  Grantors
notwithstanding any subsequent cure of an Event of Default.


                                   ARTICLE VII

                                  Miscellaneous

                  SECTION  7.01.   Notices.   All   communications  and  notices
hereunder shall (except as otherwise  expressly  permitted herein) be in writing
and  given  as  provided  in  Section   9.01  of  the  Credit   Agreement.   All
communications and notices hereunder to any Subsidiary  Guarantor shall be given
to it at its address or telecopy  number set forth on Schedule I, with a copy to
the Borrower.

                  SECTION 7.02.  Security Interest  Absolute.  All rights of the
Collateral  Agent  hereunder,  the Security  Interest and all obligations of the
Grantors  hereunder shall be absolute and unconditional  irrespective of (a) any
lack of  validity  or  enforceability  of the Credit  Agreement,  any other Loan
Document,  any  agreement  with respect to any of the  Obligations  or any other
agreement or instrument relating to any of the foregoing,  (b) any change in the
time,  manner or place of payment of, or in any other term of, all or any of the
Obligations, or any other amendment or waiver of or any consent to any departure
from the Credit  Agreement,  any other Loan  Document or any other  agreement or
instrument,  (c) any  exchange,  release or  non-perfection of any Lien on other
collateral,  or any  release  or  amendment  or  waiver of or  consent  under or
departure  from  any  guarantee,  securing  or  guaranteeing  all  or any of the
Obligations,  or (d) any other  circumstance  that might otherwise  constitute a
defense  available  to,  or a  discharge  of,  any  Grantor  in  respect  of the
Obligations or this Agreement.

                  SECTION   7.03.   Survival  of   Agreement.   All   covenants,
agreements, representations and warranties made by any Grantor herein and in the
certificates  or other  instruments  prepared or 

                                       15


delivered in connection  with or pursuant to this Agreement  shall be considered
to have been relied upon by the Secured  Parties and shall survive the making by
the Lenders of the Loans,  and the  execution and delivery to the Lenders of any
notes evidencing such Loans, regardless of any investigation made by the Lenders
or on their  behalf,  and shall  continue  in full force and  effect  until this
Agreement shall terminate.

                  SECTION  7.04.  Binding  Effect;   Several   Agreement.   This
Agreement  shall become  effective as to any Grantor when a  counterpart  hereof
executed on behalf of such Grantor shall have been  delivered to the  Collateral
Agent  and a  counterpart  hereof  shall  have  been  executed  on behalf of the
Collateral  Agent,  and  thereafter  shall be binding  upon such Grantor and the
Collateral Agent and their respective successors and assigns, and shall inure to
the benefit of such Grantor,  the Collateral Agent and the other Secured Parties
and their respective  successors and assigns,  except that no Grantor shall have
the right to assign or  transfer  its  rights or  obligations  hereunder  or any
interest  herein or in the Collateral (and any such assignment or transfer shall
be void)  except as  expressly  contemplated  by this  Agreement  or the  Credit
Agreement.  This  Agreement  shall be  construed  as a separate  agreement  with
respect to each Grantor and may be amended,  modified,  supplemented,  waived or
released  with respect to any Grantor  without the approval of any other Grantor
and without affecting the obligations of any other Grantor hereunder.

                  SECTION  7.05.  Successors  and  Assigns.   Whenever  in  this
Agreement  any of the parties  hereto is referred  to, such  reference  shall be
deemed to include the successors  and assigns of such party;  and all covenants,
promises and agreements by or on behalf of any Grantor or the  Collateral  Agent
that are  contained  in this  Agreement  shall bind and inure to the  benefit of
their respective successors and assigns.

                  SECTION   7.06.   Collateral   Agent's   Fees  and   Expenses;
Indemnification.  (a) Each  Grantor  jointly  and  severally  agrees to pay upon
demand to the Collateral  Agent the amount of any and all  reasonable  expenses,
including the reasonable  fees,  disbursements  and other charges of its counsel
and of any experts or agents, which the Collateral Agent may incur in connection
with (i) the administration of this Agreement,  (ii) the custody or preservation
of,  or the  sale  of,  collection  from or  other  realization  upon any of the
Collateral,  (iii) the exercise,  enforcement or protection of any of the rights
of the Collateral  Agent hereunder or (iv) the failure of any Grantor to perform
or observe any of the provisions hereof.

                  (b)  Without  limitation  of its  indemnification  obligations
under the other Loan  Documents,  each Grantor  jointly and severally  agrees to
indemnify the Collateral Agent and the other Indemnitees  against, and hold each
of them harmless  from, any and all losses,  claims,  damages,  liabilities  and
related expenses,  including reasonable fees, disbursements and other charges of
counsel,  incurred by or asserted against any of them arising out of, in any way
connected  with, or as a result of, the  execution,  delivery or  performance of
this Agreement or any claim,  litigation,  investigation or proceeding  relating
hereto or to the  Collateral,  whether or not any Indemnitee is a party thereto;
provided that such indemnity  shall not, as to any  Indemnitee,  be available to
the extent that such losses,  claims,  damages,  liabilities or related expenses
are determined by a court of competent  jurisdiction by final and  nonappealable
judgment to have  resulted from the gross  negligence  or willful  misconduct of
such Indemnitee.

                  (c) Any such amounts  payable as provided  hereunder  shall be
additional  Obligations secured hereby and by the other Security Documents.  The
provisions  of this Section 7.06 shall  remain  

                                       16


operative  and in full force and effect  regardless of the  termination  of this
Agreement  or any other Loan  Document,  the  consummation  of the  transactions
contemplated  hereby,  the  repayment  of any of the Loans,  the  invalidity  or
unenforceability  of any term or provision  of this  Agreement or any other Loan
Document,  or any investigation  made by or on behalf of the Collateral Agent or
any Lender.  All amounts due under this Section 7.06 shall be payable on written
demand therefor.

                  SECTION 7.07. GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED
IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

                  SECTION 7.08. Waivers;  Amendment.  (a) No failure or delay of
the Collateral Agent in exercising any power or right hereunder shall operate as
a waiver thereof,  nor shall any single or partial exercise of any such right or
power, or any abandonment or  discontinuance of steps to enforce such a right or
power,  preclude  any other or further  exercise  thereof or the exercise of any
other right or power.  The rights and remedies of the Collateral Agent hereunder
and of the Collateral  Agent, the Fronting Banks, the  Administrative  Agent and
the Lenders under the other Loan  Documents are cumulative and are not exclusive
of any rights or  remedies  that they  would  otherwise  have.  No waiver of any
provisions  of this  Agreement  or any other  Loan  Document  or  consent to any
departure by any Grantor  therefrom  shall in any event be effective  unless the
same shall be permitted by paragraph (b)  below, and then such waiver or consent
shall be effective  only in the specific  instance and for the purpose for which
given.  No notice to or demand on any  Grantor  in any case shall  entitle  such
Grantor or any other Grantor to any other or further notice or demand in similar
or other circumstances.

                  (b) Neither this  Agreement  nor any  provision  hereof may be
waived,  amended or modified  except  pursuant to an agreement or  agreements in
writing  entered into by the  Collateral  Agent and the Grantor or Grantors with
respect to which such waiver,  amendment or modification is to apply, subject to
any consent required in accordance with Section 9.08 of the Credit Agreement.

                  SECTION 7.09.  WAIVER OF JURY TRIAL.  EACH PARTY HERETO HEREBY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION  DIRECTLY OR INDIRECTLY  ARISING
OUT OF,  UNDER OR IN  CONNECTION  WITH THIS  AGREEMENT  OR ANY OF THE OTHER LOAN
DOCUMENTS.  EACH PARTY HERETO (A)  CERTIFIES  THAT NO  REPRESENTATIVE,  AGENT OR
ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,  EXPRESSLY OR OTHERWISE,  THAT SUCH
OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVER  AND (B)  ACKNOWLEDGES  THAT IT AND THE OTHER  PARTIES  HERETO  HAVE BEEN
INDUCED  TO  ENTER  INTO  THIS  AGREEMENT  AND  THE  OTHER  LOAN  DOCUMENTS,  AS
APPLICABLE,  BY, AMONG OTHER THINGS,  THE MUTUAL WAIVERS AND  CERTIFICATIONS  IN
THIS SECTION 7.09.

                  SECTION  7.10.  Severability.  In the event any one or more of
the provisions  contained in this Agreement  should be held invalid,  illegal or
unenforceable in any respect,  the validity,  legality and enforceability of the
remaining  provisions  contained  herein  shall  not in any way be  affected  or
impaired  thereby  (it being  understood  that the  invalidity  of a  particular
provision in a  particular  jurisdiction  shall not in and of itself  affect the
validity  of such  provision  in any  other  jurisdiction).  The  parties  shall
endeavor  in  good-faith  negotiations  to  replace  the  invalid,   illegal  or
unenforceable  provisions  with valid  provisions  the economic  effect of which
comes as close as  possible  to that of the  invalid,  illegal or  unenforceable
provisions.

                                       17


                  SECTION 7.11  Counterparts.  This Agreement may be executed in
two or more counterparts,  each of which shall constitute an original but all of
which when taken together shall constitute but one contract  (subject to Section
7.04),  and shall become  effective as provided in Section 7.04.  Delivery of an
executed  signature  page to this Agreement by facsimile  transmission  shall be
effective as delivery of a manually executed counterpart hereof.

                  SECTION  7.12.  Headings.  Article and Section  headings  used
herein are for the purpose of reference only, are not part of this Agreement and
are not to affect  the  construction  of, or to be taken into  consideration  in
interpreting, this Agreement.

                  SECTION 7.13. Jurisdiction; Consent to Service of Process. (a)
Each Grantor hereby irrevocably and unconditionally  submits, for itself and its
property,  to the  nonexclusive  jurisdiction  of any New  York  State  court or
Federal court of the United States of America  sitting in New York City, and any
appellate court from any thereof,  in any action or proceeding arising out of or
relating to this Agreement or the other Loan  Documents,  or for  recognition or
enforcement of any judgment,  and each of the parties hereto hereby  irrevocably
and  unconditionally  agrees  that all claims in  respect of any such  action or
proceeding  may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court.  Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other  jurisdictions  by suit on the judgment or in any other manner
provided  by law.  Nothing  in this  Agreement  shall  affect any right that the
Collateral Agent, the Administrative Agent, the Fronting Banks or any Lender may
otherwise  have to bring any action or proceeding  relating to this Agreement or
the other Loan Documents  against any Grantor or its properties in the courts of
any jurisdiction.

                  (b)  Each  Grantor  hereby  irrevocably  and   unconditionally
waives,  to the  fullest  extent  it may  legally  and  effectively  do so,  any
objection which it may now or hereafter have to the laying of venue of any suit,
action or proceeding  arising out of or relating to this  Agreement or the other
Loan  Documents  in any New York State or  Federal  court.  Each of the  parties
hereto hereby  irrevocably  waives,  to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court.

                  (c)  Each  party to this  Agreement  irrevocably  consents  to
service of process in the manner  provided for notices in Section 7.01.  Nothing
in this  Agreement  will  affected  the right of any party to this  Agreement to
serve process in any other manner permitted by law.

                  SECTION  7.14.  Termination.  This  Agreement and the Security
Interest shall terminate when all the Obligations have been indefeasibly paid in
full, the Lenders have no further  commitment to lend, the L/C Exposure has been
reduced  to zero and the  Fronting  Banks have no  further  commitment  to issue
Letters of Credit under the Credit Agreement, at which time the Collateral Agent
shall execute and deliver to the Grantors, at the Grantors' expense, all Uniform
Commercial Code termination  statements and similar documents which the Grantors
shall  reasonably  request to  evidence  such  termination.  Any  execution  and
delivery of termination  statements or documents  pursuant to this  Section 7.14
shall be without  recourse to or warranty by the Collateral  Agent. A Subsidiary
Guarantor shall automatically be released from its obligations hereunder and the
Security  Interest  in the  Collateral  of such  Subsidiary  Guarantor  shall be
automatically  released  in the  event  that  all  the  capital  stock  of  such
Subsidiary  Guarantor shall be sold,  transferred or otherwise  disposed of to a
person that is not an Affiliate of the Borrower in accordance  with the terms of
the Credit Agreement; provided that the Required Lenders shall have consented to
such sale,  transfer or other  disposition (to the extent required 

                                       18


by the  Credit  Agreement)  and the  terms  of  such  consent  did  not  provide
otherwise.

                  SECTION 7.15. Additional Grantors. Upon execution and delivery
by the Collateral Agent and a Subsidiary of an instrument in the form of Annex 2
hereto, such Subsidiary shall become a Grantor hereunder with the same force and
effect as if originally named as a Grantor herein. The execution and delivery of
any such instrument shall not require the consent of any Grantor hereunder.  The
rights and obligations of each Grantor  hereunder shall remain in full force and
effect  notwithstanding  the  addition  of any new  Grantor  as a party  to this
Agreement.


         IN  WITNESS  WHEREOF,  the  parties  hereto  have  duly  executed  this
Agreement as of the day and year first above written.

                  "Collateral  Agent")  for  the  Secured  Parties  (as  defined
                  herein).

                  A. Reference is made to (a) the Credit  Agreement  dated as of
March 12,  1996 (as amended,  supplemented  or otherwise  modified  from time to

Agreement to become a Grantor  under the  Security  Agreement in order to induce
the Lenders to make additional  Loans and the Fronting Banks to issue additional
Letters of Credit and as consideration  for Loans previously made and Letters of
Credit previously issued.

                  Accordingly, the Collateral Agent and the New Grantor agree as
follows:

Agreement,  the New Grantor by its  signature  below becomes a Grantor under the
Security Agreement with the same force and effect as if originally named therein
as a  Grantor  and the New  Grantor  hereby  (a)  agrees  to all the  terms  and
provisions of the Security  Agreement  applicable to it as a Grantor  thereunder
and (b) represents and warrants that the  representations and warranties made by
it as a Grantor thereunder are true and correct on and as of the date hereof. In
furtherance of the foregoing,  the New Grantor,  as security for the payment and
performance in full of the Obligations  (as defined in the Security  Agreement),
does  hereby  create  and grant to the  Collateral  Agent,  its  successors  and
assigns, for the benefit of the Secured Parties, their successors and assigns, a
security  interest  in and lien on all of the 



New Grantor's right,  title and interest in and to the Collateral (as defined in
the Security Agreement) of the New Grantor. Each reference to a "Grantor" in the
Security  Agreement  shall be deemed to include the New  Grantor.  The  Security
Agreement is hereby incorporated herein by reference.

                  SECTION 2. The New  Grantor  represents  and  warrants  to the
Collateral  Agent and the other Secured  Parties that this  Supplement  has been
duly authorized,  executed and delivered by it and constitutes its legal,  valid
and binding obligation, enforceable against it in accordance with its terms.

                  SECTION 3. This  Supplement  may be executed  in  counterparts
(and by different parties hereto on different counterparts), each of which shall
constitute an original,  but all of which when taken together shall constitute a
single  contract.  This  Supplement  shall become  effective when the Collateral
Agent shall have  received  counterparts  of this  Supplement  that,  when taken
together,  bear the  signatures  of the New  Grantor and the  Collateral  Agent.
Delivery  of  an  executed  signature  page  to  this  Supplement  by  facsimile
transmission  shall be as effective as delivery of a manually signed counterpart
of this Supplement.

                  SECTION 4. The New Grantor hereby represents and warrants that
(a) set forth on Schedule I  attached  hereto is a true and correct  schedule of
the  location of any and all  Collateral  of the New  Grantor and (b) set  forth
under  its  signature  hereto,  is the true and  correct  location  of the chief
executive office of the New Grantor.

                  SECTION  5.  Except  as  expressly  supplemented  hereby,  the
Security Agreement shall remain in full force and effect.

                  SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                  SECTION 7. In case any one or more of the provisions contained
in this  Supplement  should be held  invalid,  illegal or  unenforceable  in any
respect,  the validity,  legality and enforceability of the remaining provisions
contained herein and in the Security  Agreement shall not in any way be affected
or impaired  thereby (it being  understood  that the  invalidity of a particular
provision in a  particular  jurisdiction  shall not in and of itself  affect the
validity of such provision in any other jurisdiction).  The parties hereto shall
endeavor  in  good-faith  negotiations  to  replace  the  invalid,   illegal  or
unenforceable  provisions  with valid  provisions  the economic  effect of which
comes as close as  possible  to that of the  invalid,  illegal or  unenforceable
provisions.

                  SECTION 8. All  communications  and notices hereunder shall be
in writing and given as provided in Section 7.01 of the Security Agreement.  All
communications  and notices hereunder to the New Grantor shall be given to it at

Agent  for  its  reasonable  out-of-pocket  expenses  in  connection  with  this

counsel for the Collateral Agent.


                  IN WITNESS  WHEREOF,  the New Grantor and the Collateral Agent
have duly executed this  Supplement to the Security  Agreement as of the day and
year first above written.
