         thereof), or any indemnity, warranty or guaranty, payable by reason of
         loss or damage to or otherwise with respect to any of the foregoing
         Collateral).

Notwithstanding the foregoing, "Collateral" shall not include the Excluded
Assets and any general intangibles or other rights arising under any contracts,
instruments, licenses or other documents as to which the grant of a security
interest would constitute a violation of a valid and enforceable restriction in
favor of a third party on such grant, unless and until any required consents
shall have been obtained.  The Grantor shall, upon the request of the
Collateral Agent, use its best commercial efforts to obtain any such required
consent.

         SECTION 2.2.  SECURITY FOR OBLIGATIONS.  This Security Agreement
secures the due, prompt and complete payment, performance and satisfaction by
the Grantor of all indebtedness, liabilities and obligations, present or
future, direct or indirect, absolute or contingent, matured or unmatured, at
any time due or accruing due, owing by the Grantor to the Collateral Agent, the
Administrative Agent and the Term Loan Lenders pursuant to the Guarantee, and
to the Collateral Agent, the Trustee and the Holders pursuant to the Senior
Secured Note Indenture, and any ultimate unpaid balance thereof, respectively,
and in any currency, and whether incurred prior to, at the time of or
subsequent to the execution hereof (collectively, and together with the
expenses, costs and charges set out herein, the "Secured Obligations").


         SECTION 2.3.  CONTINUING SECURITY INTEREST; TRANSFER OF TERM LOAN
NOTES.  This Security Agreement shall create a continuing security interest in
the Collateral and shall

                 (a)      remain in full force and effect until the full and
         complete payment, performance and satisfaction of all of the Secured
         Obligations,

                 (b)      be binding upon the Grantor, its successors,
         transferees and assigns, and





                                     - 7 -
   8
                 (c)      inure, together with the rights and remedies of the
         Collateral Agent hereunder, to the benefit of the Collateral Agent and
         each other Secured Party.

Without limiting the generality of the foregoing clause (c), any Term Loan
Lender may assign or otherwise transfer (in whole or in part) any Term Loan
Note or Term Loan held by it to any other Person or entity, and such other
Person or entity shall thereupon become vested with all the rights and benefits
in respect thereof granted to such Term Loan Lender under any Collateral
Document or any Loan Document (including this Security Agreement) or otherwise,
subject, however, to any contrary provisions in such assignment or transfer,
and to the provisions of Section 11.11 and Article X of the Term Loan
Agreement.  Upon the full and complete payment, performance and satisfaction of
all of the Secured Obligations,  the security interest granted herein shall
terminate and all rights to the Collateral shall revert to the Grantor.  Upon
any such termination, the Collateral Agent will, at the Grantor's sole expense,
execute and deliver to the Grantor such documents as the Grantor shall
reasonably request to evidence such termination.  Upon any sale or other
transfer of Collateral permitted by the terms of the Intercreditor Agreement,
the security interest created hereunder in such Collateral (but not in the
proceeds thereof) shall be deemed to be automatically released and the
Collateral Agent will, at the Grantor's sole expense, execute and deliver to
the Grantor such documents as the Grantor shall reasonably request to evidence
such release.

         SECTION 2.4.  GRANTOR REMAINS LIABLE.  Anything herein to the contrary
notwithstanding

                 (a)  the Grantor shall remain liable under the contracts and
         agreements included in the Collateral to the extent set forth therein,
         and shall perform all of its duties and obligations under such
         contracts and agreements,

                 (b)  the exercise by the Collateral Agent of any of its rights
         hereunder shall not release the Grantor from any of its duties or
         obligations under any such contracts or agreements included in the
         Collateral, and

                 (c)  neither the Collateral Agent nor any other Secured Party
         shall have any obligation or liability under any such contracts or
         agreements included in the Collateral by reason of this Security
         Agreement, nor shall the Collateral Agent or any other Secured Party
         be obligated to perform any of the obligations or duties of the
         Grantor thereunder or to take any action to collect or enforce any
         claim for payment assigned hereunder.

         SECTION 2.5.  SECURITY INTEREST ABSOLUTE.  All rights of the
Collateral Agent and the security interests granted to the Collateral Agent
hereunder, and all obligations of the Grantor hereunder, shall be absolute and
unconditional, irrespective of

                 (a)      any lack of validity or enforceability of the
         Intercreditor Agreement, the Senior Secured Note Indenture, the Term
         Loan Agreement, any Term Loan Note, any Senior Secured Note, any
         Collateral Document or any other Loan Document;

                 (b)      the failure of any Secured Party

                 any right or remedy against the Borrower or any other Person
                 under the provisions of the Intercreditor Agreement, the
                 Senior Secured Note Indenture, the Term Loan Agreement, any
                 Term Loan Note, any Senior Secured Note, any Collateral
                 Document or any other Loan Document or otherwise, or

                          (ii)    to exercise any right or remedy against any
                 other guarantor of, or collateral securing, any Secured
                 Obligations;

                 (c)      any change in the time, manner or place of payment
         of, or in any other term of, all or any of the Secured Obligations or
         any other extension, compromise or renewal of any Secured Obligations;

                 (d)      any reduction, limitation, impairment or termination
         of any Secured Obligations for any reason, including any claim of
         waiver, release, surrender, alteration or compromise, and shall not be
         subject to (and the Grantor hereby waives any right to or claim of)
         any defense or setoff, counterclaim, recoupment or termination
         whatsoever by reason of the invalidity, illegality, nongenuineness,
         irregularity, compromise, unenforceability of, or any other event or
         occurrence affecting, any Secured Obligations or otherwise;

                 (e)      any amendment to, rescission, waiver, or other
         modification of, or any consent to departure from, any of the terms of

         and be continuing a Default of the nature set forth in Section 8.1.9
         of the Term Loan Agreement, a Default of the nature set forth in
         Clause 10 or 11 of Section 501 of the Senior Secured Note Indenture or
         an Event of Default.

                 (c)      The Collateral Agent shall have the right to apply
         any amount in the Collateral Account to the payment of any Secured
         Obligations which are due and payable or payable upon demand, or to

         Default shall exist.

         SECTION 4.1.3.  AS TO COLLATERAL.

                 (a)      Until the occurrence and continuance of a Default of
         the nature set forth in Section 8.1.9 of the Term Loan Agreement, a
         Default of the nature set forth in Clause 10 or 11 of Section 501 of
         the Senior Secured Note Indenture or an Event of Default, and such
         time as the Collateral Agent shall notify the Grantor of the
         revocation of such power and authority, the Grantor (i) may use and
         consume, in the ordinary course of its business (except as otherwise
         permitted under the Intercreditor Agreement), any raw materials, work
         in process or materials normally held by the Grantor for such purpose,
         (ii) will, at its own expense, endeavour to collect, as and when due,
         all amounts due with respect to any of the Collateral, including the
         taking of such action with respect to such collection as the
         Collateral Agent may reasonably request following the occurrence of a
         Default of the nature set forth in Section 8.1.9 of the Term Loan
         Agreement, a Default of the nature set forth in Clause 10 or 11 of
         Section 501 of the Senior Secured Note Indenture or an Event of
         Default or, in the absence of such request, as the Grantor may deem
         advisable,(iii) may grant, in the ordinary course of business (except
         as otherwise permitted under the Intercreditor Agreement), to any
         party obligated on any of the Collateral, any rebate, refund or
         allowance to which such party may be lawfully entitled, and may
         accept, in connection therewith, the return of goods, the sale or
         lease of which shall have given rise to such Collateral, and (iv) may
         commercially exploit the Intellectual Property Collateral, defend it,
         enforce its rights in it against third parties and





                                     - 13 -

         be entitled to receive any damages with respect to any infringement of
         it.  The Collateral Agent, however, may, at any time following a
         Default of the nature set forth in Section 8.1.9 of the Term Loan
         Agreement, a Default of the nature set forth in Clause 10 or 11 of
         Section 501 of the Senior Secured Note Indenture or an Event of
         Default, whether before or after any revocation of such power and
         authority or the maturity of any of the Secured Obligations, notify
         any parties obligated on any of the Collateral to make payment to the
         Collateral Agent of any amounts due or to become due thereunder and
         enforce collection of any of the Collateral by suit or otherwise and
         surrender, release, or exchange all or any part thereof, or compromise
         or extend or renew for any period (whether or not longer than the
         original period) any indebtedness thereunder or evidenced thereby.
         Upon request of the Collateral Agent following a Default of the nature
         set forth in Section 8.1.9 of the Term Loan Agreement, a Default of
         the nature set forth in Clause 10 or 11 of Section 501 of the Senior
         Secured Note Indenture or an Event of Default, the Grantor will, at
         its own expense, notify any parties obligated on any of the Collateral
         to make payment to the Collateral Agent of any amounts due or to
         become due thereunder.

                 (b)      The Collateral Agent is authorized to endorse, in the
         name of the Grantor, any item, howsoever received by the Collateral
         Agent, representing any payment on or other proceeds of any of the
         Collateral.

         Grantor, or (ii) have a valid business purpose to do otherwise, do any
         act, or omit to do any act, whereby any of the Patent Collateral may

                 (b)      the Grantor shall not, and the Grantor shall not
         permit any of its licensees to, unless the Grantor shall either (i)
         reasonably and in good faith determine (and notice of such
         determination shall have been delivered to the Collateral Agent) that
         any of the Trademark Collateral is of negligible economic value to the
         Grantor, or (ii) have a valid business purpose to do otherwise,

                          (i)     fail to continue to use any of the Trademark

                          (iii)   fail to employ all of the Trademark
                 Collateral registered with any federal, state, provincial,
                 municipal, local or foreign authority with an appropriate
                 notice of such registration,

                          (iv)    adopt or use any other Trademark which is
                 confusingly similar or a colourable imitation of any of the
                 Trademark Collateral,

                          (v)  use any of the Trademark Collateral registered
                 with any federal, state, provincial, municipal, local or
                 foreign authority except for the uses for which registration
                 or application for registration of all of the Trademark
                 Collateral has been made, and

                          (vi)    do or permit any act or knowingly omit to do
                 any act whereby any of the Trademark Collateral may lapse or
                 become invalid or unenforceable.

                 (c)      the Grantor shall not, unless the Grantor shall
         either

                          (i)     reasonably and in good faith determine (and
                 notice of such determination shall have been delivered to the
                 Collateral Agent) that any of the Copyright Collateral or any
                 of the Trade Secrets Collateral is of negligible economic
                 value to the Grantor, or

                          (ii)    have a valid business purpose to do
                 otherwise, do or permit any act or knowingly omit to do any
                 act whereby any of the Copyright Collateral or any of the
                 Trade Secrets Collateral may lapse or become invalid or
                 unenforceable or placed in the public domain except upon
                 expiration of the end of an unrenewable term of a registration
                 thereof.

                 (d)      the Grantor shall notify the Collateral Agent
         immediately if it knows, or has reason to know, that any application
         or registration relating to any material item of the Intellectual
         Property Collateral may become abandoned or dedicated to the public or
         placed in the public domain or invalid or unenforceable, or of any
         adverse determination or development (including the institution of, or
         any such determination or development in, any proceeding in the United
         States Patent and Trademark Office, the United States Copyright Office

         employees, designees or licensees file an application for the
         registration of any Intellectual Property Collateral with the United
         States Patent and Trademark Office, the United States Copyright Office
         or any similar office or agency in any other country or any political
         subdivision thereof, unless it promptly informs the Collateral Agent,
         and upon request of the Collateral Agent, executes and delivers any
         and all agreements, instruments, documents and papers as the
         Collateral Agent may reasonably request to evidence the Collateral
         Agent's

         represented thereby.

         in any proceeding before the United States Patent and Trademark
         Office, the United States Copyright Office or any similar office or
         agency in any other country or any political subdivision thereof, to
         maintain and pursue any application (and to obtain the relevant
         registration) filed with respect to, and to maintain any registration
         of, the Intellectual Property Collateral, including the filing of
         applications for renewal, affidavits of use, affidavits of
         incontestability and opposition, interference and cancellation
         proceedings and the payment of fees and taxes (except to the extent

         Agent, execute and deliver to the Collateral Agent a Patent Security
         Agreement, a Trademark Security Agreement and a Copyright Security

         respectively, and shall execute and deliver to the Collateral Agent
         any other document required to acknowledge or register or perfect the

         SECTION 4.1.6.  TRANSFERS AND OTHER LIENS.  The Grantor shall not:

                 (a)      sell, assign (by operation of law or otherwise) or
         otherwise dispose of any of the Collateral, except as permitted by the
         Intercreditor Agreement; or

                 (b)      create or suffer to exist any Lien or other charge or
         encumbrance upon or with respect to any of the Collateral to secure
         Indebtedness of any Person or entity, except for the security interest
         created by this Security Agreement and except as permitted by the
         Intercreditor Agreement.

         SECTION 4.1.7.  FURTHER ASSURANCES, ETC.  The Grantor agrees that,
from time to time at its own expense, it 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 request, in order to
perfect, preserve and protect any 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.  Without limiting
the generality of the foregoing, the Grantor will

                 (a)      if any Contract shall be evidenced by a promissory
         note or other instrument, negotiable document or chattel paper,
         deliver and pledge to the Collateral Agent hereunder such promissory
         note, instrument, negotiable document or chattel paper duly endorsed
         and accompanied by duly executed instruments of transfer or
         assignment, all in form and substance satisfactory to the Collateral
         Agent; provided, however, that unless there shall have occurred and be
         continuing a Default of the nature set forth in Section 8.1.9 of the
         Term Loan Agreement, a Default in the nature set forth in Clause 10 or
         11 of Section 501 of the Senior Secured Note Indenture or an Event of
         Default,

                          (i)     no such promissory note, instrument,
                                  negotiable document or chattel paper that has
                                  a fair market value of less than $500,000
                                  individually, or

                          (ii)    such promissory notes, instruments,
                                  negotiable documents or chattel paper that
                                  collectively have a fair market value in the
                                  aggregate of less than $1,000,000,

         shall be required to be delivered unless otherwise required pursuant
         to the Term Loan Agreement, any other Loan Document (as such term is
         defined in the Term Loan Agreement) the Senior Secured Indenture or
         any other Collateral Document;

                 (b)      execute and file such financing or continuation
         statements, or amendments thereto, and such other instruments or
         notices (including any assignment of claim form under or pursuant to
         the PPSA, any successor or amended version thereof or any regulation
         promulgated under or pursuant to any version thereof), as may be
         necessary or desirable, or as the Collateral Agent may request, in
         order to perfect and preserve the security interests and other rights
         granted or purported to be granted to the Collateral Agent hereby; and





                                     - 17 -
   18
                 (c)      furnish to the Collateral Agent, from time to time at
         the Collateral Agent's request, 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.

With respect to the foregoing and the grant of the security interest hereunder,
the Grantor hereby authorizes the Collateral Agent to file one or more
financing or continuation statements, and amendments thereto, relative to all
or any part of the Collateral without the signature of the Grantor where
permitted by law.  A carbon, photographic or other reproduction of this
Security Agreement or any financing statement covering the Collateral or any
part thereof shall be sufficient as a financing statement where permitted by
law.


                                   ARTICLE V

                              THE COLLATERAL AGENT

         SECTION 5.1.  COLLATERAL AGENT APPOINTED ATTORNEY-IN-FACT.  The
Grantor hereby irrevocably appoints the Collateral Agent the Grantor's
attorney-in-fact, with full authority in the place and stead of the Grantor and
in the name of the Grantor or otherwise, from time to time in the Collateral
Agent's discretion, following the occurrence and continuation of a Default of
the nature set forth in Section 8.1.9 of the Term Loan Agreement, a Default of
the nature set forth in Clause 10 or 11 of Section 501 of the Senior Secured
Note Indenture or an Event of Default, to take any action and to execute any
instrument which the Collateral Agent may deem necessary or advisable to
accomplish the purposes of this Security Agreement, including:

                 (a)      to ask, 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;

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

                 (c)      to file any claims or take any action or institute
         any proceedings which the Collateral Agent may deem necessary or
         desirable for the collection of any of the Collateral or otherwise to
         enforce the rights of the Collateral Agent with respect to any of the
         Collateral; and

                 (d)      to perform the affirmative obligations of the Grantor
         hereunder (including all obligations of the Grantor pursuant to
         Section 4.1.7).

The Grantor hereby acknowledges, consents and agrees that the power of attorney
granted pursuant to this Section is irrevocable and coupled with an interest.

         SECTION 5.2.  COLLATERAL AGENT MAY PERFORM.  If the Grantor fails to
perform any agreement contained herein, the Collateral Agent may itself
perform, or cause performance of,





                                     - 18 -
   19
such agreement, and the expenses of the Collateral Agent incurred in connection
therewith shall be payable by the Grantor pursuant to Section 6.2.

         SECTION 5.3.  COLLATERAL AGENT HAS NO DUTY.  In addition to, and not
in limitation of, Section 2.4, the powers conferred on the Collateral Agent
hereunder are solely to protect its interest (on behalf of the Secured Parties)
in the Collateral and shall not impose any duty on it to exercise any such
powers.  Except for reasonable care 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 or as to the taking of any necessary
steps to preserve rights against prior parties or any other rights pertaining
to any Collateral.

         SECTION 5.4.  REASONABLE CARE.  The Collateral Agent is required to
exercise reasonable care in the custody and preservation of any of the
Collateral in its possession; provided, however, the Collateral Agent shall be
deemed to have exercised reasonable care in the custody and preservation of any
of the Collateral, if it takes such action for that purpose as the Grantor
reasonably requests in writing at times other than upon the occurrence and
during the continuance of any Event of Default, but failure of the Collateral
Agent to comply with any such request at any time shall not in itself be deemed
a failure to exercise reasonable care.


                                   ARTICLE VI

                                    REMEDIES

         SECTION 6.1.  CERTAIN 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 on default under the PPSA (whether or not the PPSA
         applies to the affected Collateral) and also may

                          (i)     require the Grantor to, and the 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 which is reasonably convenient to both
                 parties, and

                          (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 the Collateral Agent
                 may deem commercially reasonable.  The Grantor agrees that, to
                 the extent notice of sale shall be required by law, at least
                 ten days' prior notice to the 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





                                     - 19 -
   20
                 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 6.2) 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 in cash of all the Secured Obligations shall be paid
         over to the Grantor or to whomsoever may be lawfully entitled to
         receive such surplus.

         SECTION 6.2.  INDEMNITY AND EXPENSES.

                 (a)      The Grantor agrees to indemnify the Collateral Agent
         from and against any and all claims, losses and liabilities arising
         out of or resulting from this Security Agreement (including
         enforcement of this Security Agreement), except claims, losses or
         liabilities resulting from the Collateral Agent's gross negligence or
         wilful misconduct.

                 (b)      The Grantor will upon demand pay to the Collateral
         Agent the amount of any and all reasonable expenses, including the
         reasonable fees and disbursements of its counsel and of any experts
         and agents, which the Collateral Agent may incur in connection with

                          (i)     the administration of this Security
                 Agreement,

                          (ii)    the custody, preservation, use or operation
                 of, or, after the occurrence and during the continuance of an
                 Event of Default, the sale of, collection from, or other
                 realization upon, any of the Collateral, and

                          (iii)   the exercise or enforcement of any of the
                 rights of the Collateral Agent or the Secured Parties
                 hereunder, or (iv) the failure by the Grantor to perform or
                 observe any of the provisions hereof.

                                  ARTICLE VII

                            MISCELLANEOUS PROVISIONS
