                   SECTION 3. REPRESENTATIONS AND WARRANTIES

      The Grantor hereby represents and warrants to the Co-Agents on behalf of
the Secured Parties as set forth in this Section 3. The Grantor agrees that the
following representations and warranties shall be deemed to have been made by
the Grantor on and as the date hereof and on and as of the Closing Date and as
of each other date on which a purchase of Senior Secured Notes from the Grantor
is made under the terms of the Amended and Restated Note Purchase Agreement, in
each case as though made on and as of each such date (or, if any such
representation or warranty is expressly stated to have been made as of a
specific date, as of such specific date).

      3.1. Power and Authority. As of the date hereof, the Grantor has the
corporate power and authority, and the legal right, to make, deliver and perform
its obligations under, and to grant the security interest in the Trademark
Collateral and the Patent Collateral to the extent provided in, and pursuant to,
this Agreement and has taken all necessary corporate action to authorize the
execution, delivery and performance of, and grant of the security interest in
the Trademark Collateral and the Patent Collateral to the extent provided in,
and pursuant to, this Agreement.

      3.2. Title; No Other Liens. As of the date hereof, except for the Liens
granted to the Administrative Agent for the benefit of the holders of Senior
Loans under the Senior Credit Documents and to the Co-Agents for the benefit of
the Secured Parties pursuant to this Agreement or the Guarantee and Collateral
Agreement and the other Liens permitted to exist pursuant to Section 8.3 of the
Amended and Restated Note Purchase Agreement, the Grantor is (or, in the case of
after-acquired Collateral, will be) the sole, legal and beneficial owner of the
entire right, title and interest in and to the material Trademarks set forth on
Schedule I hereto and the material Patents set forth in Schedule II hereto free
and clear of any and all Liens. As of the date hereof, except pursuant to the
Senior Credit Documents or except as set forth on Schedule III hereto, no
security agreement, financing statement or other public notice similar in effect
with respect to all or any part of the Collateral is on file or of record in any
public office (including, without limitation, the United States Patent and
Trademark Office), except such as may have been filed in favor of the Co-Agents
for the ratable benefit of the Secured Parties pursuant to this Agreement or the
Guarantee and Collateral Agreement and in respect of such Liens as may be
permitted pursuant to subsection 8.3 of the Amended and Restated Note Purchase
Agreement.

      3.3. Perfected Priority Liens.

            (a) As of the date hereof, this Agreement is effective to create, as
collateral security for the Secured Obligations, valid and enforceable Liens on
the Collateral in favor of the Co-Agents for the benefit of the Secured Parties
except as enforceability may be affected by bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and other similar laws relating to or
affecting creditors' rights generally, general equitable principles (whether
considered in a proceeding in equity or at law) and an implied covenant of good
faith and fair dealing.


                                       5
<PAGE>

      (b) As of the date hereof, except with respect to Liens upon Patents and
Trademarks and Patent Licenses and Trademark Licenses, which Liens, to the
extent not otherwise perfected by the filing of financing statements under the
Code in accordance herewith, would, in the case of Patents and Trademarks listed
in Schedules I and II hereto, or in the case of Patent Licenses and Trademark
Licenses listed in Schedules I and II hereto, be perfected upon the filing,
acceptance and recordation thereof in the United States Patent and Trademark
Office, upon filing of the financing statements delivered to the Co-Agents by
the Grantor on the Closing Date in the jurisdictions listed on Schedule 5.24 to
the Amended and Restated Note Purchase Agreement, which financing statements are
in proper form for filing in such jurisdictions, and the recording of this
Agreement in the United States Patent and Trademark Office, and the making of
filings after the Closing Date in any other jurisdiction in the United States as
may be necessary under any Requirement of Law, the Liens created pursuant to
this Agreement will constitute valid and perfected Liens on the Collateral in
the United States in favor of the Co-Agents for the benefit of the Secured
Parties, which Liens will be prior to all other Liens of all other Persons with
respect to the Collateral except Liens granted to the Administrative Agent for
the benefit of the holders of Senior Loans under the Senior Credit Documents,
and which Liens are enforceable as such against all creditors of and purchasers
(except to the extent that the recording of an assignment or other transfer of
title to the Co-Agents in the United States Patent and Trademark Office may be
necessary for such enforceability) from the Grantor, except as such enforcement
may be limited by bankruptcy, insolvency, reorganization, moratorium or similar
laws affecting the enforcement of creditors' rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity or
at law) or by an implied covenant of good faith and fair dealing.

      3.4. Consents. No consent of any party (other than the Grantor) to any
material Patent License or material Trademark License constituting Collateral is
required, or purports to be required, to be obtained by or on behalf of the
Grantor in connection with the execution, delivery and performance of this
Agreement that has not been obtained. Each Patent License and Trademark License
constituting Collateral is in full force and effect and constitutes a valid and
legally enforceable obligation of the Grantor and (to the knowledge of the
Grantor) each other party thereto except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditor's rights generally and by general equitable principles
(whether enforcement is sought by proceedings in equity or at law) or by an
implied covenant of good faith and fair dealing and except to the extent the
failure of any such Patent License or Trademark License constituting Collateral
to be in full force and effect or valid or legally enforceable would not be
reasonably expected, in the aggregate, to have a material adverse effect on the
value of the Collateral. No consent or authorization of, filing with or other
act by or in respect of any Governmental Authority is required in connection
with the execution, delivery, performance, validity or enforceability of any of
the Patent Licenses or Trademark Licenses constituting Collateral by any party
thereto other than those which have been duly obtained, made or performed and
are in full force and effect and those the failure of which to make, obtain or
perform would not be reasonably expected, in the aggregate, to have a material
adverse effect on the value of the Collateral. Neither the Grantor nor (to the
knowledge of the Grantor) any other party to any Patent License or Trademark
License constituting Collateral is in default in the performance or observance
of any of the terms thereof, except for


                                       6
<PAGE>

such defaults as would not reasonably be expected, in the aggregate, to have a
material adverse effect on the value of the Collateral. Except for rights
reserved in favor of the United States government, as required under law, the
right, title and interest of the Grantor in, to and under each Patent License
and Trademark License constituting Collateral are not subject to any defense,
offset, counterclaim or claim which would be reasonably expected, either
individually or in the aggregate, to have a material adverse effect on the value
of the Collateral.

      3.5. Schedules I and II are Complete; All Filings Have Been Made. Set
forth in Schedules I and II is a complete and accurate list of all material
Trademarks and material Patents owned by the Grantor as of the date hereof. As
of the date hereof, the Grantor will have made all necessary filings to protect
and maintain its interest in the Trademarks and Patents set forth in Schedules I
and II hereto, including, without limitation, all necessary filings and payments
of all maintenance fees to the United States Patent and Trademark Office to the
extent such Trademarks and Patents are material to the Grantor's business. Set
forth in Schedules I and II hereto is a complete and accurate list of all of the
material Trademark Licenses and material Patent Licenses owned by the Grantor as
of the date hereof.

      3.6. The Trademarks and Trademark Licenses are Subsisting and Not Adjudged
Invalid. As of the date hereof, each trademark registration and trademark
application of the Grantor set forth in Schedule I hereto is subsisting as of
the date hereof, and has not been adjudged invalid, unregistrable or
unenforceable, in whole or in part, and, to the best of the Grantor's knowledge,
is valid, registrable and enforceable. As of the date hereof, each of the
Trademark Licenses set forth in Schedule I hereto is validly subsisting and has
not been adjudged invalid or unenforceable, in whole or in part, and, to the
best of the Grantor's knowledge, is valid and enforceable. As of the date
hereof, the Grantor has notified the Co-Agents in writing of all uses of any
item of Trademark Collateral material to the Grantor's business of which the
Grantor is aware which could reasonably be expected to lead to such item
becoming invalid or unenforceable, including unauthorized uses by third parties
and uses which were not supported by the goodwill of the business connected with
such Collateral.

      3.7. The Patent and Patent Licenses are Subsisting and Not Adjudged
Invalid. As of the date hereof, each Patent and patent application of the
Grantor set forth in Schedule II hereto is subsisting and has not been adjudged
invalid, unpatentable or unenforceable, in whole or in part, and, to the best of
the Grantor's knowledge, is valid, patentable and enforceable. As of the date
hereof, each of the Patent Licenses set forth in Schedule II hereto is validly
subsisting and has not been adjudged invalid or unenforceable, in whole or in
part, and, to the best of the Grantor's knowledge, is valid and enforceable. As
of the date hereof, the Grantor has notified the Co-Agents in writing of all
uses of any item of Patent Collateral material to the Grantor's business of
which the Grantor is aware which could reasonably be expected to lead to such
item becoming invalid or unenforceable.

      3.8. No Previous Assignments or Releases. As of the date hereof, except
for Liens granted to the Administrative Agent for the benefit of holders of
Senior Loans under the Senior Credit Documents, the Grantor has not made any
agreement constituting a present or future assignment, sale, transfer or
encumbrance of any of the Collateral (except for any such assignment, sale,
transfer or encumbrance permitted under the Note Documents). Except as permitted
by the Senior Credit Documents, the Note Documents or as required by Law, the


                                       7
<PAGE>

Grantor has not granted any license, shop right, release, covenant not to sue,
or non-assertion assurance to any Person with respect to any material part of
the Collateral which would have a Material Adverse Effect.

      3.9. Proper Statutory Notice. The Grantor has marked its products with the
trademark registration symbol(R), the numbers of all appropriate patents, the
common law trademark symbol(TM), or the designation "patent pending," as the
case may be, to the extent that it is reasonably and commercially practicable.

      3.10. No Knowledge of Claims Likely to Arise. Except for the Trademark
Licenses and Patent Licenses listed in Schedules I and II hereto, the Grantor
has no knowledge of the existence of any right or any claim (other than as
permitted by this Agreement or the Note Documents) that is likely to be made
under or against any item of Collateral contained on Schedules I and II which
would have a Material Adverse Effect.

      3.11. No Knowledge of Existing or Threatened Claims. No claim has been
made and is continuing or, to the Grantor's knowledge, threatened that the use
by the Grantor of any item of Collateral is invalid or unenforceable or that the
use by the Grantor of any Collateral does or may violate the rights of any
Person, which would have a Material Adverse Effect. To the Grantor's knowledge,
there is currently no infringement or unauthorized use of any item of Collateral
contained on Schedules I and II hereto which would have a Material Adverse
Effect.

                              SECTION 4. COVENANTS

      The Grantor covenants and agrees with the Co-Agents and the other Secured
Parties that, from and after the date of this Agreement until the payment in
full of the Senior Secured Notes and to the extent then due and owing, all other
Secured Obligations:

      4.1. Further Documentation; Pledge of Instruments and Chattel Paper. At
any time and from time to time, upon the written request of the Co-Agents or the
Grantor, as the case may be, and at the sole expense of the Grantor, the Grantor
or the Co-Agents, as the case may be, will promptly and duly execute and deliver
such further instruments and documents and take such further action as the
Co-Agents or the Grantor, as the case may be, may reasonably request for the
purpose of obtaining or preserving the full benefits of this Agreement and of
the right and powers herein granted, including, without limitation, the filing
of any financing or continuation statements under the Uniform Commercial Code in
effect in any jurisdiction with respect to the Liens created hereby. The Grantor
also hereby authorizes the Co-Agents to file any such financing or continuation
statement without the signature of the Grantor to the extent permitted by
applicable law. A carbon, photographic or other reproduction of this Agreement
shall be sufficient as a financing statement for filing in any jurisdiction. The
Co-Agents agree to notify the Grantor and the Grantor agrees to notify the
Co-Agents of any financing or continuation statement filed by it pursuant to
this Section 4.1, provided that any failure to give any notice shall not affect
the validity or effectiveness of any the filing.


                                       8
<PAGE>

      4.2. Indemnification and Expenses. The Grantor agrees to pay, and to save
the Co-Agents, the other Secured Parties and all their respective agents,
officers, directors and successors harmless from, any and all liabilities and
reasonable costs and expenses (including, without limitation, reasonable legal
fees and expenses) (a) with respect to, or resulting from, any delay by the
Grantor in complying with any material Requirement of Law applicable to any of
the Collateral or (b) in connection with any of the transactions contemplated by
this Agreement, provided that such indemnity shall not, as to the Co-Agents, any
of the other Secured Parties or any of their respective agents, officers,
directors and successors, be available to the extent that such liabilities,
costs and expenses resulted from the gross negligence or willful misconduct of
any of the same. In any suit, proceeding or action brought by the Co-Agents or
any other Secured Party under any of the Collateral for any sum owing
thereunder, or to enforce any of the Collateral, the Grantor will save,
indemnify and keep the Co-Agents, such Secured Party and their respective
agents, officers, directors and successors harmless from and against all
expense, loss or damage suffered by reason of any defense or counterclaim raised
in any such suit, proceeding or action, except to the extent such expense, loss
or damage resulted from the gross negligence or willful misconduct of any of the
same.

      4.3. Maintenance of Records. The Grantor will keep and maintain at its own
cost and expense reasonably satisfactory and complete records of the Collateral,
and shall mark such records to evidence this Agreement and the Liens and the
security interests created hereby. For the Secured Parties' further security,
the Co-Agents for the benefit of the Secured Parties shall have a security
interest in all of the Grantor's books and records pertaining to the Collateral.

      4.4. Right of Inspection. Upon reasonable written advance notice to the
Grantor and at reasonable intervals, or at any time and from time to time after
the occurrence and during the continuation of an Event of Default, the Co-Agents
shall have reasonable access during normal business hours to all books,
correspondence and records of the Grantor, and the Co-Agents and their
representatives may examine the same, and to the extent reasonable, take
extracts therefrom and make photocopies thereof, and the Grantor agrees to
render to the Co-Agents, at the Grantor's reasonable cost and expense, such
clerical and other assistance, as may be reasonably requested with regard
thereto.

      4.5. Compliance with Laws, etc. The Grantor will comply in all material
respects with all material Requirements of Law applicable to the Collateral or
any part thereof, except to the extent that the failure to so comply would not
be reasonably expected to materially adversely affect in the aggregate the
Co-Agents' or the other Secured Parties' rights hereunder, the priority of their
Liens on the Collateral or the value of the Collateral.

      4.6. Further Identification of Collateral. The Grantor will furnish to the
Co-Agents from time to time such statements and schedules further identifying
and describing the Collateral, and such other reports in connection with the
Collateral, as the Co-Agents may reasonably request, all in reasonable detail.


                                       9
<PAGE>

      4.7. Security Interest in Any Newly Acquired Collateral. The Grantor
agrees that, should it obtain an ownership interest in any material Trademark,
Patent, Trademark License or Patent License, which is not now a part of the
Collateral, (i) the provisions of Section 2 shall automatically apply thereto,
(ii) any such Trademark, Patent, Trademark License and Patent License shall
automatically become part of the Collateral, and (iii) with respect to any
ownership interest in any such Trademark, Patent, Trademark License or Patent
License that such Grantor should obtain, it shall give notice thereof to the
Co-Agents in writing, in reasonable detail, at their addresses set forth in the
Amended and Restated Note Purchase Agreement within 45 days after the end of the
calendar quarter in which it obtains such ownership interest. The Grantor
authorizes the Co-Agents to modify this Agreement by amending Schedules I and II
hereto (and will cooperate reasonably with the Co-Agents in effecting any such
amendment) to include on Schedule I hereto any Trademark and Trademark License
and on Schedule II hereto any Patent or Patent License of which the Co-Agents
receive notice under this Section, or to prepare and file with the United States
Patent and Trademark Office a supplement to this Agreement to include any Patent
or Trademark of which the Co-Agents receive notice to under this Section.

      4.8. Maintenance of the Trademark Collateral. The Grantor agrees to take
all reasonably necessary steps, including, without limitation, in the United
States Patent and Trademark Office or in any court, to (a) maintain each
trademark registration and each Trademark License identified on Schedule I
hereto and (b) pursue each trademark application now or hereafter identified in
Schedule I hereto, including, without limitation, the filing of responses to
office actions issued by the United States Patent and Trademark Office, the
filing of applications for renewal, the filing of affidavits under Sections 8
and 15 of the United States Trademark Act, and the participation in opposition,
cancellation, infringement and misappropriation proceedings, except, in each
case in which the Grantor has reasonably determined that any of the foregoing is
not of material economic value to it. The Grantor agrees to take corresponding
steps with respect to each new or acquired trademark or service mark
registration, or application for trademark or service mark registration, or any
rights obtained under any Trademark License, in each case, which it is now or
later becomes entitled, except in each case in which the Grantor has reasonably
determined that any of the foregoing is not of material economic value to it.
Any expenses incurred in connection with such activities shall be borne by the
Grantor.

      4.9. Maintenance of the Patent Collateral. The Grantor agrees to take all
necessary steps, including, without limitation, in the United States Patent and
Trademark Office or in any court, to (a) maintain each patent and each Patent
License identified on Schedule II hereto and (b) pursue each patent application,
now or hereafter identified in Schedule II hereto, including, without
limitation, the filing of divisional, continuation, continuation-in-part and
substitute applications, the filing of applications for reissue, renewal or
extensions, the payment of maintenance fees, and the participation in
interference, reexamination, opposition, infringement and misappropriation
proceedings, except, in each case in which the Grantor has reasonably determined
that any of the foregoing is not of material economic value to it. The Grantor
agrees to take corresponding steps with respect to each new or acquired patent,
patent application, or any rights obtained under any Patent License, in each
case, to which it is now or later becomes entitled, except in each case in which
the Grantor has reasonably determined that any of the


                                       10
<PAGE>

foregoing is not of material economic value to it. Any expenses incurred in
connection with such activities shall be borne by the Grantor.

      4.10. Preservation and Protection of the Trademark Collateral and Patent
Collateral. Except as provided in Section 4.11 hereof, the Grantor shall take
all steps which it or the Co-Agents deem reasonably appropriate under the
circumstances to preserve and protect its material Trademark Collateral and
Patent Collateral.

      4.11. Grantor Shall Not Abandon any Collateral. The Grantor shall not
abandon any trademark registration, patent or any pending trademark or patent
application, in each case listed on Schedule I or Schedule II, without the
written consent of the Co-Agents, unless the Grantor shall have previously
determined that such use or the pursuit or maintenance of such trademark
registration, patent or pending trademark or patent application is not of
material economic value to it, in which case, the Grantor will, at least
annually, give notice of any such abandonment to the Co-Agents in writing, in
reasonable detail, at their addresses set forth in the Amended and Restated Note
Purchase Agreement.

      4.12. Infringement of Any Collateral. In the event that the Grantor
becomes aware that any item of the Collateral which the Grantor has reasonably
determined to be material to its business is infringed or misappropriated by a
third party, which infringement or misappropriation would reasonably be expected
to have a Material Adverse Effect, the Grantor shall notify the Co-Agents
promptly and in writing, in reasonable detail, at their addresses set forth in
the Amended and Restated Note Purchase Agreement, and shall take such actions as
the Grantor or the Co-Agents deem reasonably appropriate under the circumstances
to protect such Collateral, including, without limitation, suing for
infringement or misappropriation and for an injunction against such infringement
or misappropriation. Any expense incurred in connection with such activities
shall be borne by the Grantor. The Grantor will advise the Co-Agents promptly
and in writing, in reasonable detail, at their addresses set forth in the
Amended and Restated Note Purchase Agreement, of any adverse determination or
the institution of any proceeding (including, without limitation, the
institution of any proceeding in the United States Patent and Trademark Office
or any court) regarding any item of the Collateral which has a Material Adverse
Effect.

      4.13. Use of Statutory Notice. The Grantor shall mark its products with
the trademark registration symbol (R), the numbers of all appropriate patents,
the common law trademark symbol TM, or the designation "patent pending", as the
case may be, to the extent that it is reasonably and commercially practicable.

      4.14. Limitation on Liens on Collateral. The Grantor will not create,
incur or permit to exist, will defend the Collateral against, and will take such
other action as is reasonably necessary to remove, any material Lien or material
adverse claim on or to any of the Collateral, other than Liens created hereby
and other than as permitted under the Note Documents (including, without
limitation, any Liens permitted to exist on the Collateral pursuant to Section
8.3 of the Amended and Restated Note Purchase Agreement), and will defend the
right, title and interest of the Co-Agents and the other Secured Parties in and
to any of the Collateral against the claims and demands of all Persons
whomsoever (other than the holders of the Senior Loans), except where failure to
defend would not have a Material Adverse Effect.


                                       11
<PAGE>

      4.15. Limitations on Dispositions of Collateral. Subject to the terms of
the Intercreditor Agreement, without the prior written consent of the Co-Agents,
the Grantor will not sell, assign, transfer, exchange or otherwise dispose of,
or grant any option with respect to, the Collateral, or attempt, offer or
contract to do so, except with respect to licenses in the ordinary course of
business or as permitted by this Agreement, the Senior Credit Documents or the
Note Documents.

      4.16. Notices. The Grantor will advise the Co-Agents promptly and in
writing, in reasonable detail, at their addresses set forth in the Amended and
Restated Note Purchase Agreement, (a) of any Lien (other than Liens created
hereby or permitted under the Note Documents, including, without limitation, any
Liens permitted to exist on the Collateral pursuant to Section 8.3 of the
Amended and Restated Note Purchase Agreement) on any Patents or Trademarks and
(b) of the occurrence of any other event which would reasonably be expected in
the aggregate to have a material adverse effect on the aggregate value of the
Collateral taken as a whole or the Liens created hereunder.

             SECTION 5. CO-AGENTS' APPOINTMENT AS ATTORNEY-IN-FACT

      5.1. Powers. The Grantor hereby irrevocably constitutes and appoints each
Co-Agent and, any officer or agent of the Co-Agents, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of the Grantor and in the name of the
Grantor or in its own name, for the purpose of carrying out the terms of this
Agreement, to take any and all appropriate action and to execute any and all
documents and instruments which may be reasonably necessary or desirable to
accomplish the purposes of this Agreement to the extent permitted by law, and,
without limiting the generality of the foregoing, to the extent permitted by
law, the Grantor hereby gives each Co-Agent the power and right, on behalf of
the Grantor, without notice to or assent by the Grantor, to do, at any time when
an Event of Default has occurred and is continuing, the following, but subject
in all cases to the Intercreditor Agreement:

            (a) to execute and deliver any and all agreements, instruments,
documents, and papers as the Co-Agents may reasonably request to evidence the
Secured Parties' security interest in any of the Collateral and the goodwill of
the Grantor relating thereto or represented thereby;

            (b) in the name of the Grantor or its own name, or otherwise, to
take possession of and indorse and collect any checks, drafts, notes,
acceptances or other instruments for the payment of moneys due under any General
Intangible (to the extent that the foregoing constitute Collateral) or with
respect to any other Collateral and to file any claim or to take any other
action or institute any proceeding in any court of law or equity or otherwise
deemed appropriate by the Co-Agents for the purpose of collecting any and all
such moneys due under such General Intangible or with respect to any other
Collateral whenever payable;


                                       12
<PAGE>

            (c) to pay or discharge Liens placed on the Collateral, other than
Liens permitted under this Agreement or the other Note Documents, including,
without limitation, any liens permitted to exist on the Collateral pursuant to
Section 8.3 of the Amended and Restated Note Purchase Agreement; and

            (d) (i) to direct any party liable for any payment under any of the
Collateral to make payment of any and all moneys due or to become due thereunder
directly to the Co-Agents or as the Co-Agents shall direct; (ii) to ask for, or
demand, collect, receive payment of and receipt for, any and all moneys, claims
and other amounts due or to become due at any time in respect of or arising out
of any Collateral; (iii) to sign and indorse any invoices, freight or express
bills, bills of lading, storage or warehouse receipts, drafts against debtors,
assignments, verifications, notices and other documents in connection with any
of the Collateral; (iv) to commence and prosecute any suits, actions or
proceedings at law or in equity in any court of competent jurisdiction to
collect the Collateral or any thereof and to enforce any other right in respect
of any Collateral; (v) to defend any suit, action or proceeding brought against
the Grantor with respect to any of the Collateral; (vi) to settle, compromise or
adjust any suit, action or proceeding described in clause (v) above and, in
connection therewith, to give such discharges or releases as the Co-Agents may
deem appropriate; (vii) subject to any pre-existing reserved rights or licenses,
to assign any Patent or Trademark constituting Collateral (along with the
goodwill of the business to which any such Patent or Trademark pertains), for
such term or terms, on such conditions, and in such manner, as the Co-Agents
shall in their sole discretion determine; and (viii) generally, to sell,
transfer, pledge and make any agreement with respect to or otherwise deal with
any of the Collateral as fully and completely as though the Co-Agents were the
absolute owner thereof for all purposes, and to do, at the Co-Agents' option and
the Grantor's expense, at any time, or from time to time, all acts and things
which the Co-Agents, or either of them, deems reasonably necessary to protect,
preserve or realize upon the Collateral and the Secured Parties' Liens thereon
and to effect the intent of this Agreement, all as fully and effectively as the
Grantor might do.

The Grantor hereby ratifies all that said attorneys shall lawfully do or cause
to be done by virtue hereof. This power of attorney is a power coupled with an
interest and shall be irrevocable until the payment in full of the Senior
Secured Notes and the other Secured Obligations then due and owing.

      5.2. Other Powers. The Grantor also authorizes each Co-Agent, from time to
time if an Event of Default shall have occurred and be continuing, to execute,
in connection with any sale provided for in Section 8 hereof, any endorsements,
assignments or other instruments of conveyance or transfer with respect to the
Collateral, but subject in all cases to the Intercreditor Agreement.

      5.3. No Duty on the Part of Co-Agents or Secured Parties. The powers
conferred on the Co-Agents and the other Secured Parties hereunder are solely to
protect the Co-Agents' and the other Secured Parties' interests in the
Collateral and shall not impose any duty upon the Co-Agents or any other Secured
Party to exercise any such powers. The Co-Agents and the other Secured Parties
shall be accountable only for amounts that they actually receive as a result of
the


                                       13
<PAGE>

exercise of such powers, and neither they nor any of their officers, directors,
employees, affiliates, agents or successors shall be responsible to the Grantor
for any act or failure to act hereunder, except for gross negligence or willful
misconduct of any of the same.

      SECTION 6. PERFORMANCE BY CO-AGENTS OF GRANTOR'S SECURED OBLIGATIONS

      6.1. Performance by Co-Agents of Grantor's Secured Obligations. If the
Grantor fails to perform or comply with any of its agreements contained herein
and the Co-Agents, as provided for by the terms of this Agreement, shall perform
or comply, or otherwise cause performance or compliance, with such agreements,
the reasonable expenses of the Co-Agents incurred in connection with such
performance or compliance, together with interest thereon at a rate per annum
equal to 1.75% above the rate applicable to any Senior Secured Notes, shall be
payable by the Grantor to the Co-Agents on demand, and the Grantor's obligations
to make such payments shall constitute Secured Obligations.

                              SECTION 7. PROCEEDS

      7.1. Proceeds. It is agreed that if an Event of Default shall occur and be
continuing, but subject in all cases to the Intercreditor Agreement, (a) all
Proceeds of any Collateral received by the Grantor consisting of cash, checks
and other near-cash items shall be held by the Grantor in trust for the
Co-Agents and the other Secured Parties, segregated from other funds of the
Grantor, and shall, forthwith upon receipt by the Grantor, be turned over to the
Co-Agents in the exact form received by the Grantor (duly indorsed by the
Grantor to the Co-Agents, if required), and (b) any and all such Proceeds
received by the Co-Agents (whether from the Grantor or otherwise) shall be held
by the Co-Agents for the benefit of the Secured Parties as collateral security
for the Secured Obligations (whether matured or unmatured), and/or then or at
any time thereafter may, in the sole discretion of the Co-Agents, be applied by
the Co-Agents against the Secured Obligations then due and owing in the
following order of priority:

      FIRST, to the payment of all reasonable costs and expenses incurred by the
Co-Agents (including, without limitation, in its capacity as Co-Agents under the
Amended and Restated Note Purchase Agreement) in connection with this Agreement,
the Guarantee and Collateral Agreement, the Amended and Restated Note Purchase
Agreement, any other Note Document or any of the Secured Obligations, including,
without limitation, all court costs and the reasonable fees and expenses of its
agents and legal counsel, and any other reasonable costs or expenses incurred in
connection with the exercise by the Co-Agents (including, without limitation, in
its capacity as Co-Agents under the Amended and Restated Note Purchase
Agreement) of any right or remedy under this Agreement, the Amended and Restated
Note Purchase Agreement, or any other Note Document;

      SECOND, to the ratable satisfaction of all other Secured Obligations; and

      THIRD, to the Grantor or its successors or assigns, or to whomsoever maybe
lawfully entitled to receive the same.


                                       14
<PAGE>

                              SECTION 8. REMEDIES

      8.1. Remedies. If an Event of Default shall occur and be continuing, but
subject in all cases to the Intercreditor Agreement, the Co-Agents, on behalf of
the Secured Parties, may exercise all rights and remedies of a secured party
under the Code, and, to the extent permitted by law, all other rights and
remedies granted to the Co-Agents or any Secured Party in this Agreement and the
other Note Documents, and in any other instrument or agreement securing,
evidencing or relating to the Secured Obligations. Without limiting the
generality of the foregoing, the Co-Agents, without demand of performance or
other demand, presentment, protest, advertisement or notice of any kind (except
any notice required by law referred to below) to or upon the Grantor or any
other Person (all and each of which demands, defenses, advertisements and
notices are hereby waived), except as may be required by the terms of the
Intercreditor Agreement, may in such circumstances, to the extent permitted by
law, forthwith collect, receive, appropriate and realize upon the Collateral, or
any part thereof, and/or may forthwith sell, lease, assign, give option or
options to purchase, or otherwise dispose of and deliver the Collateral or any
part thereof (or contract to do any of the foregoing), in one or more parcels at
public or private sale or sales, at any exchange, broker's board or office of
the Co-Agents or any other Secured Party or elsewhere upon such terms and
conditions as the Co-Agents may deem advisable and at such prices as they may
deem best, for cash or on credit or for future delivery without assumption of
any credit risk. The Co-Agents or any other Secured Party shall have the right,
to the extent permitted by law, upon any such sale or sales, to purchase the
whole or any part of the Collateral so sold, free of any right or equity of
redemption in the Grantor, which right or equity is hereby waived and released.
The Grantor further agrees, at the Co-Agents' request, to assemble the
Collateral and make it available to the Co-Agents at places which the Co-Agents
shall reasonably select (subject to any directions given by the Administrative
Agent), whether at the Grantor's premises or elsewhere. In the event of any
sale, assignment, or other disposition of any of the Collateral, the goodwill of
the business connected with and symbolized by any Trademark Collateral subject
to such disposition shall be included, and the Grantor shall supply to the
Co-Agents or their designee the Grantor's know-how and expertise relating to the
Collateral subject to such disposition, and the Grantor's notebooks, studies,
reports, records, documents and things embodying the same or relating to the
inventions, processes or ideas covered by, and to the manufacture of any
products under or in connection with, the Collateral subject to such
disposition, and the Grantor's customer's lists, studies and surveys and other
records and documents relating to the distribution, marketing, advertising and
sale of products relating to the Collateral subject to such disposition. The
Co-Agents shall apply the net proceeds of any such collection, recovery,
receipt, appropriation, realization or sale, after deducting all reasonable
costs and expenses of every kind incurred therein or incidental to the care or
safekeeping of any of the Collateral or in any way relating to the Collateral or
the rights of the Co-Agents and the other Secured Parties hereunder, including,
without limitation, reasonable attorneys' fees and disbursements, to the payment
and performance in whole or in part of the Secured Obligations then due and
owing, in the order of priority specified in Section 7 hereof, and only after
such application and after the payment by the Co-Agents of any other amount
required by any provision of law, including, without limitation, Section
9-504(1)(c) of the Code, need the Co-Agents account for the surplus, if any, to
the Grantor. To the extent permitted by applicable law, (a) the Grantor waives
all claims, damages and demands it may acquire against the Co-Agents or any
other Secured Party arising out of the repossession, retention or sale of the
Collateral, other than any such claims, damages and demands that may


                                       15
<PAGE>

arise from the gross negligence or willful misconduct of any of them and (b) if
any notice of a proposed sale or other disposition of Collateral shall be
required by law, such notice shall be deemed reasonable and proper if given at
least 10 days before such sale or other disposition. The Grantor shall remain
liable for any deficiency if the proceeds of any sale or other disposition of
the Collateral are insufficient to pay in full the Senior Secured Notes and, to
the extent then due and owing, all other Secured Obligations, including, without
limitation, the reasonable fees and disbursements of any attorneys employed by
the Co-Agents or any other Secured Party to collect such deficiency, as provided
in the Amended and Restated Note Purchase Agreement.

                            SECTION 9. MISCELLANEOUS

      9.1. Limitation on Duties Regarding Preservation of Collateral. The
Co-Agents' sole duty with respect to the custody, safekeeping and physical
preservation of the Collateral in their possession, under Section 9-207 of the
Code or otherwise, shall be to deal with it in the same manner as the Co-Agents
deal with similar property for their own account. Neither the Co-Agents, any
other Secured Party, nor any of their respective directors, officers, employees,
affiliates or agents shall be liable for failure to demand, collect or realize
upon all or any part of the Collateral or for any delay in doing so or shall be
under any obligation to sell or otherwise dispose of any Collateral upon the
request of the Grantor or any other Person.

      9.2. Powers Coupled with an Interest. All authorizations and agencies
herein contained with respect to the Collateral are powers coupled with an
interest and are irrevocable until the payment in full of the Senior Secured
Notes and, to the extent then due and owing, all other Secured Obligations.

      9.3. Severability. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

      9.4. Section Headings. The Section headings used in this Agreement are for
convenience of reference only and are not to affect the construction hereof or
be taken into consideration in the interpretation hereof.

      9.5. No Waiver, Cumulative Remedies. Neither the Co-Agents nor any other
Secured Party nor the Grantor shall by any act (except by a written instrument
pursuant to Section 9.6 hereof), delay, indulgence, omission or otherwise be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default or Event of Default or in any breach of any of the terms and conditions
hereof. No failure to exercise, nor any delay in exercising, on the part of the
Co-Agents, any other Secured Party or the Grantor, any right, power or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. A
waiver by the Co-Agents, any other Secured Party or the Grantor of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Co-Agents, such other Secured Party or the Grantor
would


                                       16
<PAGE>

otherwise have on any future occasion. The rights and remedies herein provided
are cumulative, may be exercised singly or concurrently and are not exclusive of
any rights or remedies provided by law.

      9.6. Waivers and Amendments; Successors and Assigns. None of the terms or
provisions of this Agreement may be amended, supplemented, waived or otherwise
modified except by a written instrument executed by the Grantor and the
Co-Agents, provided that, if requested by the Grantor, any provision of this
Agreement for the benefit of the Co-Agents and/or the other Secured Parties may
be waived by the Co-Agents in a written letter or agreement executed by the
Co-Agents or by telex or facsimile transmission from the Co-Agents. This
Agreement shall be binding upon and will inure to the benefit of the Grantor and
its successors and assigns, and the Co-Agents and the other Secured Parties and
their respective successors, indorsees, transferees and assigns, except that
(other than in accordance with Section 8.5 of the Amended and Restated Note
Purchase Agreement) the Grantor shall not assign, transfer or delegate any of
its rights or obligations under this Agreement without the prior written consent
of the Co-Agents.

      9.7. Notices. All notices, requests and demands to or upon the respective
parties hereto shall be made in accordance with Article 15 of the Amended and
Restated Note Purchase Agreement. The Co-Agents, the Secured Parties and the
Grantor may change their respective addresses and transmission numbers for
notices by notice in the manner provided in such Article 15.

      9.8. Authority of Co-Agents. The Grantor acknowledges that the rights and
responsibilities of the Co-Agents under this Agreement with respect to any
action taken by the Co-Agents or the exercise or non-exercise by the Co-Agents
of any option, voting right, request, judgment or other right or remedy provided
for herein or resulting or arising out of this Agreement shall, as between the
Co-Agents and the other Secured Parties, be governed by the Amended and Restated
Note Purchase Agreement and by such other agreements with respect thereto as may
exist from time to time among them, but, as between the Co-Agents and the
Grantor, the Co-Agents shall be conclusively presumed to be acting as agent for
the Secured Parties with full and valid authority so to act or refrain from
acting, and the Grantor shall not be under any obligation to make any inquiry
respecting such authority.

      9.9. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF.

      9.10. Release of Collateral and Termination.

            (a) This Agreement shall remain in full force and effect and be
binding in accordance with and to the extent of its terms and the security
interest created by this Agreement shall not be released until the payment in
full of the Senior Secured Notes and the other Secured Obligations then due and
owing shall have occurred, at which time the Collateral shall be released from
the Liens created hereby, and this Agreement and all obligations (other than
those expressly stated to survive such termination) of the Co-Agents and the
Grantor hereunder shall


                                       17
<PAGE>

terminate, all without delivery of any instrument or performance of any act by
any party, and all rights to the Collateral shall revert to the Grantor,
provided that if any payment, or any part thereof, of any of the Secured
Obligations is rescinded or must otherwise be restored or returned by the
Co-Agents or any other Secured Party upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of the Grantor or any Guarantor (as
defined in the Guarantee and Collateral Agreement), or upon or as a result of
the appointment of a receiver, intervenor or conservator of, or a trustee or
similar officer for, the Grantor or any Guarantor (as defined in the Guarantee
and Collateral Agreement) or any substantial part of its property, or otherwise,
this Agreement, all rights hereunder and the Liens created hereby shall continue
to be effective, or be reinstated, as though such payments had not been made.
Upon request of the Grantor following any such termination, the Co-Agents shall
reassign (at the sole cost and expense of the Grantor) to the Grantor any
Collateral held by the Co-Agents hereunder, and execute and deliver (at the sole
cost and expense of the Grantor) to the Grantor such documents as the Grantor
shall reasonably request to evidence such termination and reassignment.

            (b) If any of the Collateral shall be sold, transferred or otherwise
disposed of by the Grantor in a transaction permitted by the Amended and
Restated Note Purchase Agreement, then the Co-Agents shall execute and deliver
to the Grantor (at the sole cost and expense of the Grantor) all releases or
other documents reasonably necessary or desirable for the release of the Liens
created hereby on such Collateral.

      9.11. Incorporation of Provisions of Guarantee and Collateral Agreement.
The Grantor hereby acknowledges and affirms that the rights and remedies of the
Co-Agents with respect to the security interest in the Collateral made and
granted hereby are more fully set forth in the Guarantee and Collateral
Agreement, the terms, conditions and other provisions of which, in so far as
they relate to the Collateral, such security interest and such rights and
remedies, are incorporated by reference herein as if fully set forth herein.
Nothing in this Agreement shall defer or impair the attachment or perfection of
any security interest in any collateral described in the Guarantee and
Collateral Agreement which would attach or be perfected pursuant to the terms of
the Guarantee and Collateral Agreement without action by the Grantor or any
other Person.

      9.12. Interpretation. In the event of a conflict between any term of this
Agreement and the terms of the Amended and Restated Note Purchase Agreement, the
terms of the Amended and Restated Note Purchase Agreement shall control.

      9.13. Integration. This Agreement and the other Note Documents represent
the entire agreement of the Grantor and the Co-Agents with respect to the
subject matter hereof and there are no promises or representations by the
Grantor, the Co-Agents or any other Secured Party relative to the subject matter
hereof not reflected or referred to herein or therein.

      9.14. Submission To Jurisdiction; Waivers. Each party hereto hereby
irrevocably and unconditionally:

            (a) submits for itself and its property in any legal action or
proceeding relating to this Agreement and the other Note Documents to which it
is a party, or for recognition and enforcement of any judgment in respect
thereof, to the non-exclusive general jurisdiction of the


                                       18

the Southern District of New York, and appellate courts from any thereof;

            (b) consents that any such action or proceeding may be brought in
such courts and waives any objection that it may now or hereafter have to the
venue of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient forum and agrees not to plead or claim
the same;

            (c) agrees that service of process in any such action or proceeding
may be effected by mailing a copy thereof by registered or certified mail (or
any substantially similar form of mail), postage prepaid, to the Grantor or the
applicable Secured Party, as the case may be, at the address referred to in
Section 9.7 or at such other address of which the Co-Agents and the Grantor
shall have been notified pursuant thereto;

            (d) agrees that nothing herein shall affect the right to effect
service of process in any other manner permitted by law or shall limit the right
to sue in any other jurisdiction; and

            (e) waives, to the maximum extent not prohibited by law, any right
it may have to claim or recover in any legal action or proceeding referred to in
this Section 9.14 any punitive damages.

      9.15. Intercreditor Agreement. The security interest and Liens granted
hereunder and the rights and remedies of the Co-Agents and the other Secured
Parties hereunder are subject to the terms of the Intercreditor Agreement. In
the event of any conflict between the terms and provisions of this Agreement and
the Intercreditor Agreement, the terms and provisions of the Intercreditor
Agreement shall govern and control.

      9.16. Counterparts. This Agreement may be executed and acknowledged by one
or more of the parties to this Agreement on any number of separate counterparts,
and all of said counterparts taken together shall be deemed to constitute one
and the same instrument.

      9.17. WAIVER OF JURY TRIAL. THE GRANTOR AND THE CO-AGENTS HEREBY
IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR
