August 12, 1999 (said Agreement, as it may be hereafter amended, supplemented or
otherwise  modified from time to time, being the Credit  Agreement) with certain
Lender  Parties  thereto,  Royal  Bank of  Canada  as  Administrative  Agent and
Collateral  Agent, and Morgan Stanley Senior Funding,  Inc., as Sole Book-Runner
and Lead Arranger.

          (2) Each Grantor is the owner of the shares (the "Pledged  Shares") of
stock set forth opposite such  Grantor's  name on and as otherwise  described in

generality of the foregoing,  this Agreement  secures the payment of all amounts
that  constitute  part of the  Secured  Obligations  and  would  be owed by such

are  unenforceable  or  not  allowable  due to the  existence  of a  bankruptcy,
reorganization or similar proceeding involving any Grantor.

          Section 3. Grantors  Remain  Liable.  Anything  herein to the contrary
notwithstanding,  (a) each Grantor  shall remain  liable under the contracts and

of the rights  hereunder  shall not release any of the Grantors  from any of its
duties or  obligations  under  the  contracts  and  agreements  included  in the

any obligation or liability  under the contracts and agreements  included in the
Collateral by reason of this Agreement or any other Loan Document, nor shall the
Collateral  Agent  or any  Secured  Party be  obligated  to  perform  any of the
obligations or duties of any of the Grantors thereunder or to take any action to
collect or enforce any claim for payment assigned hereunder.

<PAGE>

               (i) The rights of such Grantor in or to the Intellectual Property
          Collateral do not conflict with,  misappropriate  or infringe upon the
          intellectual property rights of any third party, and no claim has been
          asserted that the use of such Intellectual Property Collateral does or
          may infringe upon the intellectual property rights of any third party.

               (ii)  Such  Grantor  is the  exclusive  owner of the  entire  and
          unencumbered  right,  title and  interest  in and to the  Intellectual
          Property  Collateral  and is  entitled  to use all  such  Intellectual
          Property  Collateral without  limitation,  subject only to the license
          terms of the Licenses.

               (iii) The Intellectual  Property Collateral set forth on Schedule
          IV hereto includes all of the patents, patent applications,  trademark
          registrations   and   applications,    copyright   registrations   and
          applications and Licenses owned by such Grantor.

               (iv) The Intellectual  Property  Collateral is subsisting and has
          not been adjudged  invalid or  unenforceable  in whole or part, and to
          the best of such Grantor's knowledge,  is valid and enforceable.  Such
          Grantor is not aware of any uses of any item of Intellectual  Property
          Collateral  that  could  be  expected  to lead to such  item  becoming
          invalid or unenforceable.

               (v) Such  Grantor has made or performed  all filings,  recordings
          and other acts and has paid all  required  fees and taxes to  maintain
          and  protect  its  interest  in each and  every  item of  Intellectual
          Property Collateral in full force and effect throughout the world, and
          to protect  and  maintain  its  interest  therein  including,  without
          limitation,  recordations  of any of its  interests in the Patents and
          Trademarks  with  the  U.S.   Patent  and  Trademark   Office  and  in
          corresponding   national  and   international   patent  offices,   and
          recordation  of any of its interests in the  Copyrights  with the U.S.
          Copyright  Office  and in  corresponding  national  and  international
          copyright  offices.  Such Grantor has used proper  statutory notice in
          connection with its use of each patent, trademark and copyright of the
          Intellectual Property Collateral.

               (vi) No action, suit, investigation, litigation or proceeding has
          been  asserted  or  is  pending  or  (to  such  Grantor's   knowledge)
          threatened  against  such  Grantor  (i) based upon or  challenging  or
          seeking  to  deny  or  restrict  the  use of  any of the  Intellectual
          Property  Collateral,  or (ii) alleging that any services provided by,
          processes used by, or products  manufactured  or sold by, such Grantor
          infringe upon or misappropriate  any patent,  trademark,  copyright or
          any other  proprietary  right of any third party.  To the best of such
          Grantor's  knowledge,  no  Person is  engaging  in any  activity  that
          infringes upon or misappropriates the Intellectual Property Collateral
          or upon the  rights of such  Grantor  therein.  Except as set forth on
          Schedule IV hereto, such Grantor has not granted any license, release,
          covenant not to sue,  non-assertion  assurance,  or other right to any
          Person  with  respect  to  any  part  of  the  Intellectual   Property
          Collateral.  The consummation of the transactions  contemplated by the
          Transaction Documents will not result in the termination or impairment
          of any of the Intellectual Property Collateral.

          entire  agreement  between the  respective  licensor and licensee with
          respect to the subject  matter of such License;  (B) such License will
          not  cease to be valid and  binding  and in full  force and  effect on
          terms identical to those currently in effect as a result of the rights
          and  interest  granted  herein,  nor will the grant of such rights and
          interest  constitute  a  breach  or  default  under  such  License  or
          otherwise  give the  licensor  or licensee a right to  terminate  such
          License;  (C) such Grantor has not received any notice of  termination
          or cancellation under such License;  (D) such Grantor has not received

          default  has not been cured;  (E) such  Grantor has not granted to any
          other  third  party any  rights,  adverse  or  otherwise,  under  such
          License;  and (F)  neither  such  Grantor  nor any other party to such
          License is in breach or default in any material respect,  and no event
          has  occurred  that,  with  notice  or lapse  of time or  both,  would
          constitute   such  a  breach  or   default   or  permit   termination,
          modification  or  acceleration  under  such  License,  except for such
          events  that  could not  reasonably  be  expected  to have a  Material
          Adverse Effect.

               (viii) To the best of such Grantor's acknowledge, (A) none of the
          Trade  Secrets of such Grantor has been used,  divulged,  disclosed or
          appropriated  to the  detriment of such Grantor for the benefit of any
          other Person  other than such  Grantor;  (B) no employee,  independent
          contractor  or agent of such  Grantor  has  misappropriated  any trade
          secrets of any other Person in the course of the performance of his or
          her duties as an  employee,  independent  contractor  or agent of such
          Grantor; and (C) no employee,  independent contractor or agent of such
          Grantor  is in  default  or  breach  of any  term  of  any  employment
          agreement,   non-disclosure   agreement,   assignment   of  inventions

          protection,  ownership, development, use or transfer of such Grantor's
          Intellectual Property Collateral in any material respect.

          Section 8. Further Assurances.  (a) Each Grantor agrees that from time
to time, at the expense of such Grantor,  such Grantor will promptly execute and
deliver all further instruments and documents, and take all further action, that
may be necessary  or  desirable,  or that the  Collateral  Agent may  reasonably
request  (including,  without  limitation,  procuring third party consents),  in
order to perfect and protect any pledge, assignment or security interest granted
or purported to be granted hereby or to enable the Collateral  Agent to exercise
and enforce its rights and remedies  hereunder  with respect to any  Collateral.

the  Collateral   Agent  for  benefit  of  the  Secured   Parties   certificates
representing  Pledged  Shares  accompanied  by undated stock powers  executed in
blank;  and (v) deliver to the  Collateral  Agent evidence that all other action
that the Collateral Agent may deem reasonably necessary or desirable in order to
perfect and protect the security  interest  created by such  Grantor  under this
Agreement has been taken.

          (b) Each Grantor hereby authorizes the Collateral Agent to file one or
more financing or continuation statements,  and amendments thereto,  relating to
all or any part of the  Collateral  without the  signature of such Grantor where
permitted by law. A photocopy  or other  reproduction  of this  Agreement or any
financing  statement  covering  the  Collateral  or any  part  thereof  shall be
sufficient as a financing statement where permitted by law.

          (c) Each  Grantor will  furnish to the  Collateral  Agent from time to
time statements and schedules further  identifying and describing the Collateral
and such other reports in connection with the Collateral as the Collateral Agent
may reasonably request, all in reasonable detail.

          (d)  Each  Grantor  shall  execute  only  one  copy of  each  Assigned
Agreement and of any chattel paper and shall  deliver to the  Collateral  Agent,
forthwith upon execution thereof, such original executed copy, together with all
other  documents  ancillary  thereto or  delivered  by the  relevant  parties in
connection  therewith.  Such  Grantor  shall  mark  each  copy  of any  Assigned
Agreement  and any  chattel  paper  which is not in the sole  possession  of the
Collateral Agent with a conspicuous  legend indicating (i) that such copy is not
the  original  executed  copy,  (ii) that the original  executed  copy is in the
possession  of the  Collateral  Agent,  (iii) that such  Assigned  Agreement  or
chattel paper is subject to the security interest granted hereby,  and (iv) such
other matters as may be specified in writing from time to time by the Collateral
Agent.

          Section 9. As to Equipment and Inventory.  (a) Each Grantor shall keep
its Equipment and Inventory (other than Inventory sold in the ordinary course of
business)  at the places  therefor  specified  in Section 7(a) or, upon 30 days'
prior  written  notice  to the  Collateral  Agent,  at such  other  places  in a
jurisdiction  where all action  required by Section 8 shall have been taken with
respect to the Equipment and Inventory  (and,  upon the taking of such action in
such jurisdiction, Schedule III hereto shall be automatically amended to include
such other places).

          (b) Each  Grantor  shall  cause its  Equipment  to be  maintained  and
preserved in the same condition,  repair and working order as when new, ordinary
wear and tear excepted,  and in accordance with any  manufacturer's  manual, and
shall  forthwith,  or in the case of any loss or damage to any of such Equipment
as quickly as practicable after the occurrence thereof, make or cause to be made
all repairs,  replacements and other  improvements in connection  therewith that
are necessary or desirable to such end. Each Grantor shall  promptly  furnish to
the  Collateral  Agent a statement  respecting  any loss or damage to any of the
Equipment or Inventory of such Grantor.

          (c) Each Grantor  shall pay  promptly  when due all property and other
taxes,  assessments  and  governmental  charges or levies  imposed upon, and all
claims  (including  claims for  labor,  materials  and  supplies)  against,  its
Equipment and Inventory.  In producing the Inventory,  each Grantor shall comply
with all requirements of the Fair Labor Standards Act.

                                       13

          Section 10.  Insurance.  (a) Each Grantor  shall,  at its own expense,
maintain  insurance with respect to its Equipment and Inventory in such amounts,
against  such  risks,  in  such  form  and  with  such  insurers,  as  shall  be
satisfactory to the Collateral Agent from time to time. Each policy for property
insurance  shall  provide for all losses to be paid on behalf of the  Collateral
Agent and such  Grantor  as their  interests  may  appear,  and each  policy for
property  damage  insurance  shall provide for all losses  (except for losses of
less than  $5,000,000  per  occurrence)  to be paid  directly to the  Collateral
Agent.  Each  such  policy  shall in  addition  (i) name  such  Grantor  and the
Collateral Agent as insured parties  thereunder  (without any  representation or
warranty by or  obligation  upon the  Collateral  Agent) as their  interests may
appear, (ii) contain the agreement by the insurer that any loss thereunder shall
be payable to the  Collateral  Agent  notwithstanding  any  action,  inaction or
breach of representation  or warranty by such Grantor,  (iii) provide that there
shall be no  recourse  against the  Collateral  Agent for payment of premiums or
other amounts with respect thereto and (iv) provide that at least 10 days' prior
written  notice of  cancellation  or of lapse  shall be given to the  Collateral
Agent by the insurer.  Each  Grantor  shall,  if so requested by the  Collateral
Agent,  deliver to the Collateral  Agent original or duplicate  policies of such
insurance and, as often as the Collateral Agent may reasonably request, a report
of a reputable  insurance broker with respect to such insurance.  Further,  each
Grantor shall, at the request of the Collateral Agent, duly exercise and deliver
instruments  of  assignment  of such  insurance  policies  to  comply  with  the
requirements  of Section 8 and cause the insurers to acknowledge  notice of such
assignment.

          (b)  Reimbursement  under any  liability  insurance  maintained by any
Grantor pursuant to this Section 10 may be paid directly to the Person who shall
have incurred liability covered by such insurance. In case of any loss involving
damage to Equipment or Inventory  when  subsection (c) of this Section 10 is not
applicable,  the applicable Grantor shall make or cause to be made the necessary
repairs to or replacements of such Equipment or Inventory as deemed desirable in
the reasonable opinion of the Grantor,  and any proceeds of insurance maintained
by such  Grantor  pursuant to this  Section 10 shall be paid to such  Grantor as
reimbursement for the costs of such repairs or replacements.

          (c) Upon the occurrence  and during the  continuance of any Default or
the actual or  constructive  total loss (in excess of $5,000,000 per occurrence)
of any  Equipment  or  Inventory,  all  insurance  payments  in  respect of such
Equipment or Inventory  shall be paid to and applied by the Collateral  Agent as
specified in Section 20(b).

          Section 11. Place of Perfection;  Records;  Collection of Receivables.
(a) Each  Grantor  shall keep its chief  place of business  and chief  executive
office and the office where it keeps its records concerning the Collateral,  and
any copies of the  Assigned  Agreements  not  required  to be  delivered  to the
Collateral  Agent  hereunder and any copies of all chattel paper not required to
be delivered to the Collateral Agent hereunder that evidence Receivables, at the
location  therefor  specified  in Section  7(a) or, upon 30 days' prior  written
notice to the Collateral Agent, at such other locations in a jurisdiction  where
all  actions  required  by Section 8 shall  have been taken with  respect to the
Collateral  of such  Grantor.  Each Grantor will hold and preserve such records,
Assigned  Agreements  and chattel paper and will permit  representatives  of the
Collateral Agent at any time during normal business hours upon reasonable notice
to inspect and make abstracts from such records, Assigned Agreements and chattel
paper.  If the  jurisdiction of the securities  intermediary  that maintains the
security account carrying the Pledged  Security  Entitlements  shall change from
that  jurisdiction  specified in Section  7(f),  the  applicable  Grantor  shall
promptly   notify  the  Collateral   Agent  of  such  change  and  of  such  new
jurisdiction.

                                       14

          (b) Except as otherwise  provided in this subsection (b), each Grantor
shall continue to collect, at its own expense,  all amounts due or to become due
such Grantor under the Receivables in the manner such Grantor currently collects
such amounts. In connection with such collections made in respect of Receivables
owing from a Person being an affiliate  of such  Grantor,  such Grantor may take
(and,  at the  Collateral  Agent's  direction,  shall  take) such action as such
Grantor or the Collateral  Agent may  reasonably  deem necessary or advisable to
enforce or expedite collection of the Receivables;  provided,  however, that the
Collateral  Agent shall have the right at any time,  upon written notice to such
Grantor of its intention to do so, to notify the Obligors under any  Receivables
of the assignment of such Receivables to the Collateral Agent and to direct such
Obligors to make  payment of all  amounts  due or to become due to such  Grantor
thereunder  directly to the  Collateral  Agent or its  designee  and,  upon such
notification  and at the expense of such Grantor,  to enforce  collection of any
such Receivables directly against the relevant Obligor, and to adjust, settle or
compromise  the amount or payment  thereof,  in the same  manner and to the same
extent as such Grantor might have done. In connection with such collections made
in respect of Receivables  owing from a Person not an affiliate of such Grantor,
such Grantor may take (and, at the Collateral  Agent's  direction,  shall take),
after the occurrence and during the  continuance of any Default,  such action as
such Grantor or the Collateral  Agent may reasonably deem necessary or advisable
to enforce or expedite collection of the Receivables;  provided,  however,  that
the  Collateral  Agent shall have the right at any time after the occurrence and
during the  continuance  of any Default,  upon written notice to such Grantor of
its  intention to do so, to notify the  Obligors  under any  Receivables  of the
assignment  of such  Receivables  to the  Collateral  Agent and to  direct  such
Obligors to make  payment of all  amounts  due or to become due to such  Grantor
thereunder  directly to the  Collateral  Agent or its  designee  and,  upon such
notification  and at the expense of such Grantor,  to enforce  collection of any
such Receivables directly against the relevant Obligor, and to adjust, settle or
compromise  the amount or payment  thereof,  in the same  manner and to the same
extent as such  Grantor  might have done.  After  receipt by such Grantor of the
notice from the  Collateral  Agent  referred to in the proviso to the  preceding
sentences, (i) all amounts and proceeds (including instruments) received by such
Grantor in respect of the Receivables shall be received in trust for the benefit
of the Collateral Agent hereunder,  shall be segregated from other funds of such
Grantor and shall be  forthwith  paid over to the  Collateral  Agent in the same
form as so received (with any necessary indorsement) and (ii) such Grantor shall
not  adjust,  settle or  compromise  the amount or  payment  of any  Receivable,
release  wholly or partly any Obligor  thereof,  or allow any credit or discount
thereon.

          (c) No Grantor  will  permit or consent  to the  subordination  of its
right to payment under any of the  Receivables  or the Related  Contracts to any
other indebtedness or obligations of the Obligor thereof.

          SECTION 12.  As to Intellectual Property Collateral.

          (a) With respect to each item of its Intellectual Property Collateral,
each Grantor  agrees to take, at its expense,  all necessary  steps,  including,
without limitation,  in the U.S. Patent and Trademark Office, the U.S. Copyright
Office and any other  governmental  authority,  to (i) maintain the validity and
enforceability  of  each  such  item of  Intellectual  Property  Collateral  and
maintain each such item of  Intellectual  Property  Collateral in full force and
effect,  and (ii)  pursue  the  registration  and  maintenance  of each  patent,
trademark,  or copyright registration or application,  now or hereafter included
in the  Intellectual  Property  Collateral of such Grantor,  including,  without
limitation,  the payment of required fees and taxes,  the filing of responses to
office  actions  issued  by the  U.S.  Patent  and  Trademark  Office,  the U.S.


                                       15
<PAGE>

Copyright Office or other governmental  authorities,  the filing of applications
for renewal or extension,  the filing of affidavits  under  Sections 8 and 15 of
the   U.S.   Trademark   Act,   the   filing   of   divisional,    continuation,
continuation-in-part,  reissue  and  renewal  applications  or  extensions,  the
payment   of   maintenance   fees  and  the   participation   in   interference,
reexamination,   opposition,  cancellation,  infringement  and  misappropriation
proceedings.  No Grantor  shall,  without the written  consent of the Collateral
Agent,  discontinue  use  of or  otherwise  abandon  any  Intellectual  Property
Collateral,  or abandon any right to file an  application  for  letters  patent,
trademark,  or copyright,  unless such Grantor shall have previously  determined
that  such use or the  pursuit  or  maintenance  of such  Intellectual  Property
Collateral is no longer desirable in the conduct of such Grantor's  business and
that the loss thereof would not be reasonably  likely to have a Material Adverse
Effect,  in which  case,  such  Grantor  will  give  prompt  notice  of any such
abandonment to the Collateral Agent.

          (b) Each Grantor  agrees  promptly to notify the  Collateral  Agent if
such Grantor learns (i) that any item of the  Intellectual  Property  Collateral
may  have  become   abandoned,   placed  in  the  public   domain,   invalid  or
unenforceable,  or of any adverse  determination  or development  regarding such
Grantor's ownership of any of the Intellectual  Property Collateral or its right
to register the same or to keep and  maintain  and enforce the same,  or (ii) of
any adverse  determination  or the  institution  of any  proceeding  (including,
without  limitation,  the  institution of any proceeding in the U.S.  Patent and
Trademark Office or any court)  regarding any item of the Intellectual  Property
Collateral.

          (c) In the event that any Grantor  becomes  aware that any item of the
Intellectual  Property  Collateral is being  infringed or  misappropriated  by a
third party,  such Grantor shall promptly notify the Collateral  Agent and shall
take such actions, at its expense, as such Grantor or the Collateral Agent deems
reasonable and appropriate  under the circumstances to protect such Intellectual
Property Collateral,  including,  without limitation,  suing for infringement or
misappropriation   and  for  an   injunction   against  such   infringement   or
misappropriation.

          (d) Each Grantor shall use proper  statutory notice in connection with
its use of each item of its Intellectual  Property Collateral.  No Grantor shall
do or  permit  any  act or  knowingly  omit  to do any  act  whereby  any of its
Intellectual Property Collateral may lapse or become invalid or unenforceable or
placed in the public domain.

          (e) Each Grantor shall take all steps which it or the Collateral Agent
deems reasonable and appropriate under the circumstances to preserve and protect
each  item  of  its  Intellectual   Property  Collateral,   including,   without
limitation,  maintaining the quality of any and all products or services used or
provided in connection with any of the  Trademarks,  consistent with the quality
of the  products  and  services  as of the date  hereof,  and  taking  all steps
necessary to ensure that all licensed  users of any of the  Trademarks  use such
consistent standards of quality.

          (f) With respect to its Intellectual Property Collateral, each Grantor
agrees to execute an agreement, in substantially the form set forth in Exhibit D
hereto (an  "Intellectual  Property  Security  Agreement"),  for  recording  the
security interest granted hereunder to the Collateral Agent in such Intellectual
Property  Collateral  with  the  U.S.  Patent  and  Trademark  Office,  the U.S.
Copyright Office and any other governmental authorities necessary to perfect the
security interest hereunder in such Intellectual Property Collateral.

                                       16
<PAGE>

          (g) Each Grantor agrees that,  should it obtain an ownership  interest
in any item of the  type set  forth  in  Section  1(g)  which is not on the date
hereof  a part of the  Intellectual  Property  Collateral  (the  "After-Acquired
Intellectual  Property"),  (i) the  provisions of Section 1 shall  automatically
apply thereto,  (ii) any such After-Acquired  Intellectual  Property and, in the
case  of  trademarks,  the  goodwill  of the  business  connected  therewith  or
symbolized thereby, shall automatically become part of the Intellectual Property
Collateral  subject to the terms and  conditions of this  Agreement with respect
thereto,  (iii) such Grantor  shall give prompt  written  notice  thereof to the
Collateral Agent in accordance  herewith and (iv) such Grantor shall execute and
deliver to the Collateral  Agent an IP Security  Agreement  Supplement  covering
such After-Acquired  Intellectual Property as "Additional Collateral" thereunder
and as defined therein,  and shall record such IP Security Agreement  Supplement
with the U.S. Patent and Trademark  Office,  the U.S.  Copyright  Office and any
other  governmental  authorities  necessary  to perfect  the  security  interest
hereunder in such After-Acquired Intellectual Property.

          Section 13.  Voting Rights; Dividends; Etc.  (a)  So long as no
Event of Default shall have occurred and be continuing:

          (i) Each Grantor  shall be entitled to exercise any and all voting and
     other consensual rights  pertaining to its Security  Collateral or any part
     thereof for any purpose not  inconsistent  with the terms of this Agreement
     or the other Loan Documents; provided, however, that such Grantor shall not
     exercise or refrain from  exercising  any such right if, in the  Collateral
     Agent's  judgment,  such action would have a material adverse effect on the
     value of the Security Collateral or any part thereof.

          (ii) Each Grantor  shall be entitled to receive and retain any and all
     dividends, interest and other distributions paid in respect of its Security
     Collateral; provided, however, that any and all

               (A) dividends,  interest and other  distributions paid or payable
          other than in cash in respect of, and  instruments  and other property
          received,  receivable  or otherwise  distributed  in respect of, or in
          exchange for, such Security Collateral,

               (B) dividends and other  distributions paid or payable in cash in
          respect of such Security  Collateral  in connection  with a partial or
          total  liquidation or dissolution or in connection with a reduction of
          capital, capital surplus or paid-in-surplus and

               (C) cash paid,  payable or  otherwise  distributed  in respect of
          principal  of, or in  redemption  of, or in exchange for, any Security
          Collateral

     shall be, and shall be forthwith  delivered to the Collateral Agent to hold
     as, Security Collateral and shall, if received by such Grantor, be received
     in trust for the benefit of the Collateral  Agent,  be segregated  from the
     other  property or funds of such Grantor and be forthwith  delivered to the
     Collateral  Agent as  Security  Collateral  in the same form as so received
     (with any necessary indorsement).

          (iii) The  Collateral  Agent shall execute and deliver (or cause to be
     executed  and  delivered)  to each  Grantor  all  such  proxies  and  other


                                       17
<PAGE>

     instruments  as such  Grantor  may  reasonably  request  for the purpose of
     enabling  such  Grantor to exercise  the voting and other rights that it is
     entitled to exercise  pursuant  to  paragraph  (i) above and to receive the
     dividends or interest  payments that it is authorized to receive and retain
     pursuant to paragraph (ii) above.

          (b)     Upon the occurrence and during the continuance of a Default
or an Event of Default:

          (i) All  rights  of each  Grantor  (x) to  exercise  or  refrain  from
     exercising the voting and other  consensual  rights that it would otherwise
     be entitled to exercise  pursuant to Section 13(a)(i) shall, upon notice to
     such  Grantor  by the  Collateral  Agent,  cease  and  (y) to  receive  the
     dividends,  interest  and other  distributions  that it would  otherwise be
     authorized  to receive  and retain  pursuant  to  Section  13(a)(ii)  shall
     automatically  cease,  and all such rights shall thereupon become vested in
     the Collateral Agent, which shall thereupon have the sole right to exercise
     or refrain from exercising such voting and other  consensual  rights and to
     receive and hold as Security Collateral such dividends,  interest and other
     distributions.

          (ii) All dividends, interest and other distributions that are received
     by each Grantor contrary to the provisions of paragraph (i) of this Section
     13(b) shall be received in trust for the benefit of the  Collateral  Agent,
     shall be segregated from other funds of such Grantor and shall be forthwith
     paid over to the Collateral  Agent as Security  Collateral in the same form
     as so received (with any necessary indorsement).

          Section 14.  As to the Assigned Agreements.  (a)  Each Grantor shall
at its expense:

          (i) perform and observe all the terms and  provisions  of the Assigned
     Agreements  to be  performed  or  observed  by it,  maintain  the  Assigned
     Agreements  in full force and effect,  enforce the Assigned  Agreements  in
     accordance with their terms and take all such reasonable action to such end
     as may be from time to time requested by the Collateral Agent; and

          (ii) furnish to the  Collateral  Agent  promptly upon receipt  thereof
     copies of all  notices,  requests  and  other  documents  received  by such
     Grantor under or pursuant to the Assigned Agreements, and from time to time
     (A) furnish to the Collateral Agent such information and reports  regarding
     the Collateral as the Collateral Agent may reasonably  request and (B) upon
     request of the  Collateral  Agent make to each other party to any  Assigned
     Agreement  such  demands and requests  for  information  and reports or for
     action as such Grantor is entitled to make thereunder.

          (b) Each Grantor agrees that it shall not:

          (i) cancel or terminate any Assigned Agreement or consent to or accept
     any cancellation or termination  thereof,  except in the ordinary course of
     business  and in a manner that would not  reasonably  be expected to have a
     Material Adverse Effect;

          (ii) amend or  otherwise  modify any  Assigned  Agreement  or give any
     consent, waiver or approval thereunder;

                                       18
<PAGE>

          (iii) waive any default under or breach of any Assigned Agreement; or

          (iv) take any other action in connection  with any Assigned  Agreement
     that would  materially  impair the value of the  interest or rights of such
     Grantor  thereunder or that would materially  impair the interest or rights
     of any Secured Party.

          (c) Each  Grantor  hereby  consents on its behalf and on behalf of its
Subsidiaries to the assignment and pledge to the Collateral Agent for benefit of
the Secured  Parties of each  Assigned  Agreement  to which it is a party by any
other Grantor hereunder.

          Section 15.  Payments  Under the  Assigned  Agreements.  Each  Grantor
agrees,  and has  effectively  so  instructed  each other party to each Assigned
Agreement,  that all payments due or to become due under or in  connection  with
such  Assigned  Agreement  shall be made in  accordance  with  the  terms of the
consents referred to in Section 7(g) above.

          Section 16.  Transfers and Other Liens;  Additional  Shares.  (a) Each
Grantor  agrees  that it shall not (i) other  than in  accordance  with the Loan
Documents,  sell, assign (by operation of law or otherwise) or otherwise dispose
of, or grant any option with respect to, any of the Collateral,  except sales of
Inventory in the ordinary course of business,  or (ii) create or suffer to exist
any Lien upon or with  respect to any of the  Collateral  except for the pledge,
assignment and security interest created by this Agreement.

          (b) Each  Grantor  agrees  that it shall (i) cause each  issuer of the
Pledged  Shares not to issue any stock or other  securities in addition to or in
substitution  for the  Pledged  Shares  issued  by such  issuer,  except to such
Grantor, and (ii) pledge hereunder,  immediately upon its acquisition  (directly
or  indirectly)  thereof,  any and all  additional  shares  of  stock  or  other
securities of each issuer of the Pledged Shares.

          Section 17. Collateral Agent Appointed Attorney-in-Fact.  Each Grantor
hereby    irrevocably    appoints   the   Collateral    Agent   such   Grantor's
attorney-in-fact, with full authority in the place and stead of such Grantor and
in the name of such Grantor or  otherwise,  from time to time in the  Collateral
Agent's  discretion,  to take any action and to execute any instrument  that the
Collateral  Agent may deem  necessary or advisable to accomplish the purposes of
this Agreement, including, without limitation:

          (a)  to  obtain  and  adjust  insurance  required  to be  paid  to the
     Collateral Agent pursuant to Section 10,

          (b) to ask for, demand, collect, sue for, recover, compromise, receive
     and give acquittance and receipts for moneys due and to become due under or
     in respect of any of the Collateral,

          (c) to receive,  indorse and collect any drafts or other  instruments,
     documents and chattel  paper,  in connection  with clause (a) or (b) above,
     and

                                       19
<PAGE>

          (d) to file any claims or take any action or institute any proceedings
     that  the  Collateral  Agent  may  deem  necessary  or  desirable  for  the
     collection of any of the Collateral or otherwise to enforce compliance with
     the terms and  conditions  of any  Assigned  Agreement or the rights of the
     Collateral Agent with respect to any of the Collateral.

          Section 18.  Collateral  Agent May  Perform.  If any Grantor  fails to
perform any agreement contained herein, the Collateral Agent may itself perform,
or cause  performance  of, such  agreement,  and the expenses of the  Collateral
Agent  incurred in connection  therewith  shall be payable by such Grantor under
Section 22(b).

          Section 19. The Collateral Agent's Duties. The powers conferred on the
Collateral Agent hereunder are solely to protect the Secured  Parties'  interest
in the  Collateral  and shall not impose any duty upon it to  exercise  any such
powers.  Except for the safe custody of any Collateral in its possession and the
accounting for moneys actually  received by it hereunder,  the Collateral  Agent
shall have no duty as to any  Collateral,  as to  ascertaining  or taking action
with  respect to calls,  conversions,  exchanges,  maturities,  tenders or other
matters  relative to any Collateral,  whether or not any Secured Party has or is
deemed to have  knowledge of such matters,  or as to the taking of any necessary
steps to preserve  rights against any parties or any other rights  pertaining to
any  Collateral.  The  Collateral  Agent  shall  be  deemed  to  have  exercised
reasonable  care  in the  custody  and  preservation  of any  Collateral  in its
possession if such Collateral is accorded treatment  substantially equal to that
which it accords its own property.

          (b) Anything  contained  herein to the contrary  notwithstanding,  the
Collateral Agent may from time to time, when the Collateral Agent deems it to be
necessary,  appoint one or more subagents (each a "Subagent") for the Collateral
Agent hereunder with respect to all or any part of the Collateral.  In the event
that  the  Collateral  Agent  so  appoints  any  Subagent  with  respect  to any
Collateral,  (i) the assignment  and pledge of such  Collateral and the security
interest  granted in such  Collateral by each Grantor  hereunder shall be deemed
for purposes of this Security  Agreement to have been made to such Subagent,  in
addition  to the  Collateral  Agent,  for the  ratable  benefit  of the  Secured
Parties,  as security for the Secured  Obligations  of such  Grantor,  (ii) such
Subagent shall  automatically  be vested,  in addition to the Collateral  Agent,
with all rights,  powers,  privileges,  interests and remedies of the Collateral
Agent hereunder with respect to such Collateral,  and (iii) the term "Collateral
Agent,"  when  used  herein  in  relation  to any  rights,  powers,  privileges,
interests and remedies of the Collateral  Agent with respect to such Collateral,
shall include such Subagent;  provided,  however, that no such Subagent shall be
authorized  to take any action with  respect to any such  Collateral  unless and
except to the extent expressly authorized in writing by the Collateral Agent.

          Section 20.  Remedies.  If any Event of Default shall have occurred
and be continuing:

          (a) The Collateral Agent may exercise in respect of the Collateral, in
     addition to other  rights and  remedies  provided  for herein or  otherwise
     available  to it,  all the  rights  and  remedies  of a secured  party upon
     default  under the N.Y.  Uniform  Commercial  Code (whether or not the N.Y.
     Uniform  Commercial  Code applies to the affected  Collateral) and also may
     (i) require any of the Grantors to, and each Grantor  hereby agrees that it
     will at its expense and upon  request of the  Collateral  Agent  forthwith,
     assemble all or part of the Collateral as directed by the Collateral  Agent
     and make it available to the  Collateral  Agent at a place to be designated
     by the Collateral  Agent that is reasonably  convenient to both parties and


                                       20

     (ii) without notice except as specified  below,  sell the Collateral or any
     part  thereof in one or more parcels at public or private  sale,  at any of
     the  Collateral  Agent's  offices or elsewhere,  for cash, on credit or for
     future delivery, and upon such other terms as are commercially  reasonable;
     (iii) occupy any premises  owned or leased by any of the Grantors where the
     Collateral  or any part  thereof is  assembled  or located for a reasonable
     period in order to  effectuate  its rights and remedies  hereunder or under
     law, without obligation to such Grantor in respect of such occupation;  and
     (iv) exercise any and all rights and remedies of any of the Grantors  under
     or in connection  with the Assigned  Agreements,  the  Receivables  and the
     Related  Contracts or otherwise  in respect of the  Collateral,  including,
     without  limitation,  any and all  rights  of such  Grantor  to  demand  or
     otherwise  require  payment  of any amount  under,  or  performance  of any
     provision  of, the Assigned  Agreements,  the  Receivables  and the Related
     Contracts.  Each Grantor agrees that, to the extent notice of sale shall be
     required by law, at least ten days'  notice to such Grantor of the time and
     place of any public sale or the time after which any private  sale is to be
     made shall constitute reasonable  notification.  The Collateral Agent shall
     not be obligated  to make any sale of  Collateral  regardless  of notice of
     sale  having  been given.  The  Collateral  Agent may adjourn any public or
     private sale from time to time by  announcement at the time and place fixed
     therefor,  and such sale may,  without further notice,  be made at the time
     and place to which it was so adjourned.

          (b) All cash proceeds  received by the Collateral  Agent in respect of
     any sale of,  collection from, or other realization upon all or any part of
     the Collateral  may, in the discretion of the Collateral  Agent, be held by
     the  Collateral  Agent  as  collateral  for,  and/or  then  or at any  time
     thereafter  applied (after payment of any amounts payable to the Collateral
     Agent pursuant to Section 22) in whole or in part by the  Collateral  Agent
     for the ratable benefit of the Secured Parties against,  all or any part of
     the Secured  Obligations in such order as the Collateral Agent shall elect.
     Any surplus of such cash or cash proceeds held by the Collateral  Agent and
     remaining  after  payment in full of all the Secured  Obligations  shall be
     paid  over to the  applicable  Grantor  or to  whomsoever  may be  lawfully
     entitled to receive such surplus.

          (c) All payments  received by each Grantor under or in connection with
     any Assigned  Agreement or otherwise in respect of the Collateral  shall be
     received  in  trust  for the  benefit  of the  Collateral  Agent,  shall be
     segregated  from other funds of such  Grantor and shall be  forthwith  paid
     over to the  Collateral  Agent in the same  form as so  received  (with any
     necessary indorsement).

          (d) The Collateral  Agent may, without notice to any Grantor except as
     required by law and at any time or from time to time,  charge,  set-off and
     otherwise apply all or any part of the Secured Obligations against the Cash
     Collateral Account or the L/C Cash Collateral Account or any part thereof.

          (e) In the  event  of any  sale  or  other  disposition  of any of the
     Intellectual  Property  Collateral  of any  Grantor,  the  goodwill  of the
     business  connected with and  symbolized by any Trademarks  subject to such
     sale or other disposition shall be included therein, and such Grantor shall
     supply to the Collateral Agent or its designee such Grantor's  know-how and
     expertise,  and documents and things relating to any Intellectual  Property

                                       21
<PAGE>

     Collateral  subject to such sale or other  disposition,  and such Grantor's
     customer   lists  and  other  records  and   documents   relating  to  such
     Intellectual  Property  Collateral  and to the  manufacture,  distribution,
     advertising and sale of products and services of such Grantor.

          Section 21.  Registration  Rights. With respect to Security Collateral
issued by entities (controlled by a Grantor) where the securities are registered
under Section 12(b) or 12(g) of the  Securities  Act of 1934, if the  Collateral
Agent shall  determine  to exercise its right to sell all or any of the Security
Collateral pursuant to Section 20, each Grantor agrees that, upon request of the
Collateral Agent, such Grantor will, at its own expense:

          (a)  execute  and  deliver,  and cause  each  issuer  of the  Security
     Collateral  contemplated to be sold and the directors and officers  thereof
     to execute and deliver, all such instruments and documents, and do or cause
     to be done all such other acts and things,  as may be necessary  or, in the
     opinion of the  Collateral  Agent,  advisable  to  register  such  Security
     Collateral under the provisions of the Securities Act of 1933, as from time
     to time amended (the "Securities Act"), to cause the registration statement
     relating  thereto  to become  effective  and to remain  effective  for such
     period as prospectuses  are required by law to be furnished and to make all
     amendments and supplements  thereto and to the related  prospectus that, in
     the opinion of the  Collateral  Agent,  are necessary or advisable,  all in
     conformity  with the  requirements  of the Securities Act and the rules and
     regulations of the Securities and Exchange Commission applicable thereto;


          (b) use its best efforts to qualify the Security  Collateral under the
     state   securities   or  "Blue  Sky"  laws  and  to  obtain  all  necessary
     governmental  approvals  for  the  sale  of  the  Security  Collateral,  as
     requested by the Collateral Agent;

          (c) cause each such issuer to make available to its security  holders,
     as soon as  practicable,  an  earnings  statement  that  will  satisfy  the
     provisions of Section 11(a) of the Securities Act;

          (d)  provide  the  Collateral  Agent with such other  information  and
     projections as may be necessary or, in the opinion of the Collateral Agent,
     advisable  to  enable  the  Collateral  Agent  to  effect  the sale of such
     Security Collateral; and

          (e) do or cause to be done all such  other  acts and  things as may be
     necessary to make such sale of the Security  Collateral or any part thereof
     valid and binding and in compliance with applicable law.

The Collateral Agent is authorized,  in connection with any sale of the Security
Collateral  pursuant  to Section  19, to deliver or  otherwise  disclose  to any
prospective purchaser of the Security Collateral (i) any registration  statement
or prospectus,  and all supplements and amendments thereto, prepared pursuant to
clause (a) above,  (ii) any information and projections  provided to it pursuant
to clause (d) above and (iii) any other  information in its possession  relating
to the Security Collateral.

          Section  22.  Indemnity  and  Expenses.  (a) Each  Grantor  agrees  to
indemnify the Collateral  Agent from and against any and all claims,  losses and
liabilities growing out of or resulting from this Agreement (including,  without
limitation, enforcement of this Agreement), except claims, losses or liabilities
resulting from the Collateral  Agent's gross negligence or willful misconduct as
determined by a final judgment of a court of competent jurisdiction.

          (b) Each  Grantor  will upon  demand pay to the  Collateral  Agent the
amount of any and all reasonable  expenses,  including the  reasonable  fees and
expenses of its counsel and of any experts and agents, that the Collateral Agent
may incur in connection with (i) the administration of this Agreement,  (ii) the
custody,  preservation,  use or operation of, or the sale of, collection from or
other realization upon, any of the Collateral, (iii) the exercise or enforcement
of any of the rights of the Collateral Agent or the Secured Parties hereunder or
(iv) the  failure by such  Grantor to perform or observe  any of the  provisions
hereof.

          Section 23.  Amendments;  Waivers;  Etc. (a) No amendment or waiver of
any provision of this Agreement,  and no consent to any departure by any Grantor
herefrom,  shall in any event be  effective  unless the same shall be in writing
and signed by the  Collateral  Agent,  and then such waiver or consent  shall be
effective only in the specific  instance and for the specific  purpose for which
given.

          (b) No failure on the part of the Collateral Agent to exercise, and no
delay in exercising any right, power or privilege hereunder,  shall operate as a
waiver  thereof;  nor shall any single or partial  exercise  of any such  right,
power or  privilege  preclude  any  other or  further  exercise  thereof  or the
exercise of any other right, power or privilege.

          (c) Upon the  execution  and  delivery  by any  Person  of a  security
agreement  supplement  in  substantially  the form of  Exhibit A hereto  (each a
"Security  Agreement  Supplement"),  (i) such Person  shall be referred to as an
"Additional  Grantor" and shall be and become a Grantor,  and each  reference in
this  Agreement  to  "Grantor"  shall  also  mean  and be a  reference  to  such
Additional  Grantor and (ii) the Schedules  attached to each Security  Agreement
Supplement  shall  be  incorporated  into and  become  a part of and  supplement
Schedules  I  through  VI  hereto,  and the  Collateral  Agent may  attach  such
Schedules as supplements to such Schedules, and each reference to such Schedules
shall  mean and be a  reference  to such  Schedules,  as  supplemented  pursuant
hereto.

          Section   24.   Addresses   for   Notices.   All   notices  and  other
communications  provided for hereunder shall be in writing  (including  telecopy
communication) and, mailed (by certified mail), telecopied, or delivered by hand
to the Borrowers or to the  Collateral  Agent,  as the case may be, in each case
addressed to such Person at its address specified in the Credit Agreement or, as
to any other  Grantor at its address set forth below the name of such Grantor on
the signature pages hereto, or to the Security Agreement  Supplement to which it

address as shall be designated  by such party in a written  notice to each other
party complying as to delivery with the terms of this Section.  All such notices
and other communications shall, when mailed (by certified mail), telecopied,  or

by  telecopier  of an executed  counterpart  of any  amendment  or waiver of any

          Section 25. Continuing Security Interest; Assignments under the Credit
Agreement.  This Agreement  shall create a continuing  security  interest in the
Collateral  and shall (a) remain in full force and effect until the later of (i)
the payment in full in cash of the Secured Obligations and (ii) the later of the
Tranche A  Termination  Date,  the Tranche B Termination  Date,  and the Working
Capital  Termination Date, (b) be binding upon each Grantor,  its successors and
assigns and (c) inure,  together with the rights and remedies of the  Collateral
Agent hereunder, to the benefit of the Collateral Agent, the Secured Parties and
their  respective  successors,  transferees  and assigns.  Without  limiting the
generality of the foregoing clause (c), any Lender Party may assign or otherwise
transfer  all or any  portion  of its rights  and  obligations  under the Credit
Agreement (including,  without limitation, all or any portion of its Commitment,
the Advances  owing to it and the Note or Notes held by it to any other  Person,

transfer or other  disposition of any item of Collateral in accordance  with the
terms of the Loan  Documents  (other  than sales of  Inventory  in the  ordinary
course of business),  the  Collateral  Agent will, at the  applicable  Grantor's
expense,  execute and deliver to such  Grantor  such  documents  as such Grantor
shall reasonably request to evidence the release of such item of Collateral from
the assignment and security interest granted hereby; provided, however, that (i)
at the time of such request and such release no Default  shall have occurred and
be  continuing,  (ii)  the  applicable  Grantor  shall  have  delivered  to  the
Collateral  Agent,  at least ten Business Days prior to the date of the proposed
release, a written request for release describing the item of Collateral and the
terms of the sale, lease,  transfer or other  disposition in reasonable  detail,
including the price thereof and any expenses in connection  therewith,  together

required to be applied in accordance  with Section 2.05 of the Credit  Agreement
shall be paid to, or in  accordance  with the  instructions  of, the  Collateral
Agent at the closing.

          (b) Upon the later of (i) the  payment in full in cash of the  Secured
Obligations, and (ii) the later of the Tranche A Termination Date, the Tranche B
Termination  Date,  and  the  Working  Capital  Termination  Date,  the  pledge,
assignment and security  interest  granted hereby shall terminate and all rights
to the  Collateral  shall  revert  to the  applicable  Grantor.  Upon  any  such
termination,  the Collateral  Agent will, at the applicable  Grantor's  expense,
execute  and  deliver to such  Grantor  such  documents  as such  Grantor  shall
reasonably request to evidence such termination.

the L/C Cash  Collateral  Account.  If requested by a Borrower,  the  Collateral
Agent  will,  subject to the  provisions  of Section  20,  from time to time (a)
invest  amounts  on  deposit  in the Cash  Collateral  Account  and the L/C Cash
Collateral  Account in such Cash Equivalents (as to which all action required by
Section 8 shall have been taken) as such Borrower may select and the  Collateral
Agent may approve and (b) invest interest paid on the Cash Equivalents  referred
to in clause (a) above, and reinvest other proceeds of any such Cash Equivalents
that may mature or be sold, in each case in such Cash  Equivalents  (as to which
all actions  required by Section 8 shall have been taken) as such  Borrower  may
select and the Collateral Agent may approve (the Cash Equivalents referred to in
clauses (a) and (b) above being collectively "Collateral Investments"). Interest
and proceeds that are not invested or reinvested  in Collateral  Investments  as

                                       24

provided above shall be deposited and held in the Cash Collateral Account or the
L/C Cash Collateral Account, as the case may be.

          Section 28. Execution in Counterparts.  This Agreement may be executed
in any number of counterparts, each of which when so executed shall be deemed to
be an original and all of which taken together shall constitute one and the same
agreement.  Delivery of an  executed  counterpart  of a  signature  page to this
Agreement by telecopier  shall be effective as delivery of an original  executed
counterpart of this Agreement.

          Section  29. The  Mortgages.  In the event that any of the  Collateral
hereunder is also subject to a valid and enforceable Lien under the terms of any
Mortgage and the terms of such Mortgage are inconsistent  with the terms of this
Agreement,  then with  respect to such  Collateral,  the terms of such  Mortgage
shall be  controlling  in the case of fixtures and leases,  letting and licenses
of, and contracts and agreements relating to the lease of real property, and the
terms  of  this  Agreement  shall  be  controlling  in the  case  of  all  other
Collateral.

          Section 30.  Governing  Law. This  Agreement  shall be governed by and
construed in  accordance  with the laws of the State of New York,  except to the
extent that the validity or perfection of the security  interest  hereunder,  or
remedies hereunder,  in respect of any particular Collateral are governed by the
laws of a jurisdiction other than the State of New York.

York.
