                    (e) Each of the Schedules and Exhibits attached hereto is
hereby incorporated into and shall constitute part of this Security Agreement.

         Section 2. GRANT OF SECURITY INTEREST; NO ASSUMPTION OF LIABILITY.

                    (a) GRANT OF SECURITY INTEREST. As security for the payment
and performance in full of the Secured Obligations, each of the Grantors hereby
bargains, sells, conveys, assigns, sets over, mortgages, pledges, hypothecates
and transfers to the Trustee, for the benefit of the Holders, and hereby grants
to the Trustee, for the benefit of the Holders, a security interest in, all of
the right, title and interest of such Grantor in, to and under the Collateral
(the "SECURITY INTEREST"). Without limiting the foregoing, each Grantor hereby
authorizes the Trustee to file one or more financing statements, continuation
statements, filings with the U.S. Patent and Trademark Office or the U.S.
Copyright Office (or any successor office or any similar office in any other
country) or other documents for the purpose of perfecting, confirming,
continuing, enforcing or protecting the Security Interest granted by each of the
Grantors, without the signature of any Grantor, and naming any Grantor or the
Grantors, as applicable, as debtors and the Trustee as secured party. Each
Grantor further agrees that such financing statements may describe the
Collateral owned or held by it or on its behalf in the same manner as described
herein or may contain an indication or description of collateral that describes
such Collateral in any other manner that the Trustee may determine, in its sole
and absolute discretion, is necessary, advisable or prudent to perfect the
Security Interest granted by such Grantor, including describing such property as
"all assets" or "all personal property."

                    (b) REVISIONS TO THE UCC. For the avoidance of doubt, it is
expressly understood and agreed that, to the extent the UCC is revised after the
date hereof such that the definition of any of the foregoing terms included in
the description or definition of the Collateral is changed, the parties hereto
desire that any property which is included in such changed definitions, but
which would not otherwise be included in the Security Interest on the date
hereof, nevertheless be included in the Security Interest upon the effective
date of such revision. Notwithstanding the immediately preceding sentence,


                                       8
<PAGE>

the Security Interest is intended to apply immediately on the Applicable Date to
all of the Collateral to the fullest extent permitted by applicable law,
regardless of whether any particular item of the Collateral was then subject to
the UCC.

                    (c) CERTAIN LIMITED EXCLUSIONS. Notwithstanding anything
herein to the contrary, in no event shall the Collateral include the Excluded
Assets.

                    (d) SECURITY FOR SECURED OBLIGATIONS. This Security
Agreement secures, and the Collateral is collateral security for, the prompt and
complete payment or performance in full when due, whether at stated maturity, by
required prepayment, declaration, acceleration, demand or otherwise (including
the payment of amounts that would become due but for the operation of the
automatic stay under Section 362(a) of Title 11 of the United States Code, or
any similar provision of any other bankruptcy, insolvency, receivership or other
similar law), of all Secured Obligations.

                    (e) NO ASSUMPTION OF LIABILITY. The Security Interest is
granted as security only and shall not subject the Trustee or any Holder to, or
in any way alter or modify, any obligation or liability of any Grantor with
respect to or arising out of the Collateral.

                    (f) INTERCREDITOR AGREEMENT. Notwithstanding anything herein
to the contrary, the relative rights and remedies of the Trustee hereunder and
the Administrative Agent (or Replacement Agent) shall be subject to and governed
by the terms of the Intercreditor Agreement at any time the Intercreditor
Agreement is in effect. In the event of any inconsistency between the terms
hereof and the Intercreditor Agreement, the Intercreditor Agreement shall
control at any time the Intercreditor Agreement is in effect.

         Section 3. DELIVERY OF THE COLLATERAL.

                    Subject to Section 6, each of the Grantors agrees promptly
to deliver or cause to be delivered to the Trustee (or to the Administrative
Agent or a Replacement Agent during the effectiveness of the Intercreditor
Agreement) any and all notes, chattel paper, instruments, certificates and
documents covering, evidencing or representing any of the Pledged Securities
included in the Collateral owned or held by or on behalf of such Grantor, in
each case accompanied by (i) in the case of any notes, chattel paper,
instruments or stock certificates, stock powers duly executed in blank or other
instruments of transfer satisfactory to the Trustee and such other instruments
and documents as the Trustee may reasonably request and (ii) in all other cases,
proper instruments of assignment duly executed by such Grantor and such other
instruments or documents as the Trustee may reasonably request. Each Grantor
will cause any Pledged Debt owed or owing to such Grantor by any Person to be
evidenced by a duly executed promissory note that is pledged and delivered to
the Trustee (or to the Administrative Agent or a Replacement Agent during the
effectiveness of the Intercreditor Agreement) pursuant to the terms thereof.

         Section 4. REPRESENTATIONS AND WARRANTIES.

                    Each of the Grantors, jointly with the others and severally,
represents and warrants to the Trustee and the Holders that:

Applicable Date become bound (whether as a result of merger or otherwise) as

theretofore been terminated.

                    (d) Such Grantor has good and valid rights in, and title to,
the Collateral with respect to which it has purported to grant the Security
Interest, except for Liens expressly permitted pursuant to the Indenture
Documents, and as to all Collateral whether now existing or hereafter acquired,
will continue to own or have such rights in each item of Collateral, in each
case free and clear of any and all Liens, rights or claims of all other Persons,
except for Liens expressly permitted pursuant to the Indenture Documents.

                    (e) All actions and consents, including all filings,
notices, registrations and recordings, necessary or desirable to create, perfect
and ensure the first priority (subject only to Liens expressly permitted by the
Indenture or the Intercreditor Agreement) of the Security Interest in the
Collateral owned or held by it or on its behalf or for the exercise by the
Trustee of any voting or other rights provided for in this Security Agreement or
the exercise of any remedies in respect of any such Collateral have been made or
obtained, (i) except for the filing of UCC financing statements naming such
Grantor as "debtor" and the Trustee as "secured party", or the making of other
appropriate filings, registrations or recordings, containing a description of
such Collateral in the U.S. Patent and Trademark Office, the U.S. Copyright
office and each other applicable governmental, municipal or other office
specified on Schedule II hereto or to the applicable Supplement, (ii) except for
any such Collateral as to which the representations and warranties in this
Section 4(e) would not be true solely by virtue of such Collateral having been
used or disposed of in a manner expressly permitted hereunder or under any other
Indenture Document, and (iii) except to the extent that such Security Interest
may not be perfected by filing, registering, recording or taking any other
action in the United States.

                    (f) All Collateral owned or held by it or on its behalf is
owned or held by it or on its behalf free and clear of any Lien, except for

case of each of clauses (i), (ii) and (iii) above, for Liens expressly permitted
by the Indenture.

                    (g) The Security Interest in the Collateral owned or held by

Holders, the rights of the Trustee in such Collateral as set forth herein and

                    (h) Such Grantor has full power and authority to grant to

                                       10
<PAGE>

                    (i) The Diligence Certificate, to the extent it relates to
such Grantor or any of its property, has been duly prepared, completed and
executed and the information set forth therein is true, correct and complete in

Office and the U.S. Copyright Office pursuant to 35 U.S.C. Section 261, 15
U.S.C. Section 1060 or 17 U.S.C. Section 205, and the regulations thereunder, as

of the Holders) in respect of all Collateral consisting of Patents, Trademarks
and Copyrights owned or held by or on behalf of such Grantor in which a security
interest may be perfected by filing, recording or registration in the United
States (or any political subdivision thereof) and its territories and
possessions, or in any other necessary jurisdiction, and no further or
subsequent material filing, refiling, recording, rerecording, registration or

                    (k) The Security Interest constitutes (i) a legal and valid
security interest in all the Collateral owned or held by or on behalf of such
Grantor securing the payment and performance of the Secured Obligations, (ii)

Grantor has performed all acts and has paid all renewal, maintenance, and other
fees and taxes required to maintain each and every registration and application

any other Intellectual Property that is material to the conduct of the business
of such Grantor or the business of the Grantors as a whole, is valid and

or proceeding before any court or administrative authority challenging the
validity of, such Grantor's rights to register, or such Grantor's rights to own

pending or, to the best of such Grantor's knowledge, threatened.

upon any trademark, patent, copyright, trade secret or similar intellectual
property right owned or controlled by a third party; no claim has been made that
the use of any Intellectual Property owned or used by such Grantor (or any of
its respective licensees) violates the asserted rights of any third party.

                    (q) To the best of such Grantor's knowledge, no third party
is infringing upon any Intellectual Property owned or used by such Grantor, or
any of its respective licensees.

                    (r) No settlement or consents, covenants not to sue,
non-assertion assurances, or releases have been entered into by such Grantor or
to which such Grantor is bound that adversely affect such Grantor's rights to
own or use any Intellectual Property.

                    (s) No authorization, approval or other action by, and no
notice to or filing with, any governmental authority or regulatory body is
required for either (i) the pledge or grant by such Grantor of the Liens
purported to be created in favor of the Trustee hereunder or (ii) the exercise
by Trustee of any rights or remedies in respect of any Collateral (whether
specifically granted or created hereunder or created or provided for by
applicable law), except (A) for the filings contemplated by clause (k) above and
(B) as may be required, in connection with the disposition of any Investment
Related Property, by laws generally affecting the offering and sale of
securities.

         Section 5. COVENANTS AND AGREEMENTS.

                    Each Grantor hereby covenants and agrees as follows:

                    (a) It will promptly notify the Trustee in writing of any
change (i) in its legal name or in any trade name used to identify it in the
conduct of its business or in the ownership of its properties, (ii) in the
location of its chief executive office, (iii) in its identity or legal or
organizational structure, including its type of organization, or its
jurisdiction of organization, or (iv) in its federal


                                       12
<PAGE>

employer identification number or its organizational identification number (if
any). Upon request by the Trustee, it will promptly notify the Trustee in
writing of any change in its principal place of business or any office in which
it maintains books or records relating to any of the Collateral owned or held by
it or on its behalf or any office or facility at which any such Collateral is
located (including the establishment of any such new office or facility). It
agrees not to effect or permit any change referred to in the preceding sentence
unless all filings have been made under the UCC or otherwise that are required
in order for the Trustee to continue at all times following such change to have
a valid, legal and perfected security interest in all the Collateral with the
same priority in effect prior to such change.

                    (b) It shall maintain, at its own cost and expense, such
complete and accurate Records with respect to the Collateral owned or held by it
or on its behalf as is consistent with its current practices and in accordance
with such prudent and standard practices used in industries that are the same as
or similar to those in which it is engaged, but in any event to include complete
accounting Records indicating all payments and proceeds received with respect to
any part of such Collateral, and, at such time or times as the Trustee may
reasonably request, promptly to prepare and deliver to the Trustee a duly
certified schedule or schedules in form and detail satisfactory to the Trustee
showing the identity and amount of any and all such Collateral.

                    (c) It shall, at its own cost and expense, take any and all
actions necessary to defend title to the Collateral owned or held by it or on
its behalf against all Persons and to defend the Security Interest in such
Collateral and the priority thereof against any Lien or other interest not
expressly permitted by the Indenture or Intercreditor Agreement, and in
furtherance thereof, it shall not take, or permit to be taken, any action not
otherwise expressly permitted by the Indenture that could impair the Security
Interest or the priority thereof or the Trustee's or any Holder's rights in or
to such Collateral.

                    (d) It shall, at its own expense, execute, acknowledge,
deliver and cause to be duly filed all such further instruments and documents
and take all such actions as the Trustee may from time to time reasonably
request to preserve, protect and perfect the Security Interest granted by it and
the rights and remedies created hereby, including the payment of any fees and
taxes required in connection with its execution and delivery of this Security
Agreement, the granting by it of the Security Interest and the filing of any
financing statements or other documents in connection herewith or therewith.
Such Grantor also agrees to supplement this Security Agreement by supplementing
the Schedules hereto in order to specifically identify any asset or item owned
or held by it or on its behalf acquired by such Grantor after the date hereof
that constitutes Intellectual Property or Commercial Tort Claims pledged as
Collateral hereunder and to use its best efforts to take such action as shall be
necessary in order that all representations and warranties hereunder shall be
true and correct with respect to such Collateral within 30 days after the date
such Grantor has notified the Trustee of such additional Collateral. If such
additional Collateral includes any U.S. registered Patents, Trademarks and
Copyrights, such supplement shall be accompanied by a copy of this Security
Agreement, as so supplemented, and any other documents necessary for recording
the Trustee's Security Interest in such U.S. registered Patents, Trademarks and
Copyrights with the U.S. Patent and Trademark Office or the U.S. Copyright
Office, as applicable.

                    (e) The Trustee and such Persons as the Trustee may
reasonably designate shall have the right, at the cost and expense of such
Grantor, to reasonably inspect all of its Records (and to make extracts and
copies from such Records), to discuss its affairs with its officers and
independent accountants and to verify under reasonable procedures the validity,
amount, quality, quantity, value, condition and status of, or any other matter
relating to, the Collateral owned or held by or on behalf of such Grantor,
including, in the case of Collateral in the possession of any third person, by
contacting contract parties or other obligors thereon or any third person
possessing such Collateral for the purpose of making such a verification. The
Trustee shall have the absolute right to share on a confidential basis any



                                       13
<PAGE>

information it gains from such inspection or verification with any Holder.

                    (f) At its option, the Trustee may discharge past due taxes,
assessments, charges, fees, Liens, security interests or other encumbrances at
any time levied or placed on the Collateral owned or held by or on behalf of
such Grantor, and not permitted by the Indenture, and may pay for the
maintenance and preservation of such Collateral to the extent such Grantor fails
to do so as required by the Indenture Documents, and such Grantor agrees,
jointly with the other Grantors and severally, to reimburse the Trustee on
demand for any payment made or any expense incurred by the Trustee pursuant to
the foregoing authorization; PROVIDED that nothing in this subsection shall be
interpreted as excusing any Grantor from the performance of, or imposing any
obligation on the Trustee or any Holder to cure or perform, any covenants or
other promises of any Grantor with respect to taxes, assessments, charges, fees,
Liens, security interests or other encumbrances and maintenance as set forth
herein or in the other Indenture Documents.

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

                    (h) It shall remain liable to observe and perform all the
conditions and obligations to be observed and performed by it under each
contract, agreement or instrument relating to the Collateral owned or held by it
or on its behalf, all in accordance with the terms and conditions thereof, and
it agrees, jointly with the other Grantors and severally, to indemnify and hold
harmless the Trustee and the Holders from and against any and all liability for
such performance.

                    (i) It shall not permit any Inventory with an aggregate
value of more than $250,000 to be in the possession or control of any
warehouseman, bailee, agent or processor at any time unless such warehouseman,
bailee, agent or processor shall have been notified of the Security Interest and
shall have agreed in writing to hold such Inventory subject to the Security
Interest and the instructions of the Trustee and to waive and release any Lien
held by it with respect to such Inventory, whether arising by operation of law
or otherwise.

                    (j) It shall not grant any extension of the time of payment
of any of the Accounts Receivable or any of the Pledged Debt, compromise,
compound or settle the same for less than the full amount thereof, release,
wholly or partly, any person liable for the payment thereof or allow any credit
or discount whatsoever thereon, other than extensions, credits, discounts,
compromises or settlements granted or made in the ordinary course of business
and consistent with its current practices and in accordance with such prudent
and standard practices used in industries that are the same as or similar to
those in which such Grantor is engaged.

                    (k) It shall, at its own expense, maintain or cause to be
maintained insurance covering physical loss or damage to the Inventory and
Equipment in accordance with Section 4.6 of the Indenture, which insurance shall
be against all risks. All policies covering such insurance (i) shall contain a
standard loss payable clause and, during the effectiveness of the Intercreditor
Agreement, shall name the Administrative Agent (or Replacement Agent) as sole
loss payee, and at any time during which the Intercreditor Agreement is no
longer in effect, shall name the Trustee as loss payee in respect of each claim
relating to the Collateral and resulting in a payment thereunder, and (ii) shall
be indorsed to provide, in respect of the interests of the Trustee and the
Holders, that (A) the Trustee shall be an additional insured, (B) 30 days' prior
written notice of any cancellation or modification thereof or any


                                       14
<PAGE>

reduction of amounts payable thereunder shall be given to the Trustee, and (C)
in the event that such Grantor at any time or times shall fail to pay any
premium in whole or part relating to any such policy, the Trustee may, in its
sole discretion, pay such premium. Such Grantor irrevocably makes, constitutes
and appoints the Trustee (and all officers, employees or agents designated by
the Trustee) as such Grantor's true and lawful agent (and attorney-in-fact) for
the purpose, upon the occurrence and during the continuance of an Event of
Default, of making, settling and adjusting claims in respect of Collateral under
policies of insurance, endorsing the name of such Grantor on any check, draft,
instrument or other item of payment for the proceeds of such policies of
insurance and for making all determinations and decisions with respect thereto.
In the event that such Grantor at any time or times shall fail to obtain or
maintain any of the policies of insurance required hereby or to pay any premium
in whole or part relating thereto, the Trustee may, without waiving or releasing
any obligation or liability of the Grantors hereunder or any Event of Default,
in its sole discretion, obtain and maintain such policies of insurance and pay
such premium and take any other actions with respect thereto as the Trustee
deems advisable. All sums disbursed by the Trustee in connection with this
paragraph, including reasonable attorneys' fees, court costs, expenses and other
charges relating thereto, shall be payable, upon demand, by the Grantors to the
Trustee and shall be additional Secured Obligations secured hereby.

                    (l) It shall legend upon request by the Trustee its Accounts
Receivable, its Pledged Debt and its books, records and documents evidencing or
pertaining thereto with an appropriate reference to the fact that such Accounts
Receivable have been assigned to the Trustee for the benefit of the Holders and
that the Trustee has a security interest therein.

                    (m) It shall not, nor shall it permit any of its licensees
to, do any act, or omit to do any act, whereby any Patent that is material to
the conduct of such Grantor's business or the business of the Grantors as a
whole may become invalidated or dedicated to the public, and it shall continue
to mark any products covered by any such Patent with the relevant patent number
as necessary and sufficient to establish and preserve its maximum rights under
applicable patent laws. It shall (either itself or through its licensees or its
sublicensees), for each Trademark material to the conduct of such Grantor's
business, (i) maintain such Trademark in full force free from any claim of
abandonment or invalidity for non-use, (ii) maintain the quality of products and
services offered under such Trademark, (iii) display such Trademark with notice
of Federal or foreign registration to the extent necessary and sufficient to
establish and preserve its rights under applicable law, (iv) not knowingly use
or knowingly permit the use of such Trademark in violation of any third party
valid and legal rights. It shall (either itself or through licensees), for each
work covered by a material Copyright, continue to publish, reproduce, display,
adopt and distribute the work with appropriate copyright notice as necessary and
sufficient to establish and preserve its maximum rights under applicable
copyright laws. Such Grantor shall take all actions necessary or advisable to
ensure that any Intellectual Property material to the conduct of its business
does not become abandoned, lost or dedicated to the public, and shall notify the
Trustee of any adverse determination or development (including the institution
of, or any such determination or development in, any proceeding in the U.S.
Patent and Trademark Office, U.S. Copyright Office or any court or similar
office of any country) regarding such Grantor's ownership of any Intellectual
Property, its right to register the same, or to keep and maintain the same. Each
Grantor shall, within 105 days of the creation or acquisition of any
Copyrightable work which is material to the business of such Grantor or the
Grantors as a whole, apply to register the Copyright in the U.S. Copyright
Office. With respect to any material Copyrightable work that has been
exclusively licensed to any Grantor, such Grantor shall use its best efforts to
cause the licensor thereof to register the Copyright in the U.S. Copyright
Office and shall promptly record its rights in such License in the U.S.
Copyright Office. If any Grantor, either itself or through any agent, employee,
licensee or designee, shall file an application for any Patent, Trademark or
Copyright (or for the registration of any Trademark or Copyright) with the U.S.
Patent and Trademark Office, U.S. Copyright Office or any office or agency in
any political subdivision of the United States or in any other country or any
political subdivision thereof, it shall notify the Trustee



                                       15
<PAGE>

in writing within 60 days of such filing, and, upon the request of the Trustee,
shall promptly execute and deliver any and all agreements, instruments,
documents and papers as the Trustee may request to evidence the Trustee's
security interest in such Patent, Trademark or Copyright. Such Grantor hereby
appoints the Trustee as its attorney-in-fact to execute and file such writings
for the foregoing purposes, all acts of such attorney being hereby ratified and
confirmed; such power, being coupled with an interest, is irrevocable. Such
Grantor will take all necessary steps that are consistent with the practice in
any proceeding before the U.S. Patent and Trademark Office, U.S. Copyright
Office or any office or agency in any political subdivision of the United States
or in any other country or any political subdivision thereof, to maintain and
pursue each material application relating to the Patents, Trademarks and/or
Copyrights (and to obtain the relevant grant or registration) and to maintain
each issued Patent and each registration of the Trademarks and Copyrights that
is material to the conduct of such Grantor's business, including timely filings
of applications for renewal, affidavits of use, affidavits of incontestability
and payment of maintenance fees, and, if consistent with good business judgment,
to initiate opposition, interference and cancellation proceedings against third
parties. In the event that such Grantor has reason to believe that any
Collateral consisting of a Patent, Trademark or Copyright material to the
conduct of such Grantor's business has been or is about to be infringed,
misappropriated or diluted by a third party, such Grantor shall, if consistent
with good business judgment, promptly sue for infringement, misappropriation or
dilution and to recover any and all damages for such infringement,
misappropriation or dilution, and take such other actions as are appropriate
under the circumstances to protect such Collateral. Upon and during the
continuance of an Event of Default, such Grantor shall use its best efforts to
obtain all requisite consents or approvals by the licensor of each License to
effect the assignment of all of such Grantor's right, title and interest
thereunder to the Trustee. Except as expressly permitted under the Indenture or
the Intercreditor Agreement, the Grantors will not execute, and there will not
be on file in any public office, any financing statement, security agreement or
other document or instruments, other financing statements, security agreements,
or other documents or instruments filed or to be filed in favor of the Trustee
for the benefit of the Holders.

         Section 6. INVESTMENT RELATED PROPERTY.

                    (a) REPRESENTATIONS AND WARRANTIES. Each of the Grantors,
jointly with the other Grantors and severally, represents and warrants to the
Trustee and the Holders that Schedule III hereto or to the applicable Supplement
sets forth, as of the Applicable Date, all of the Deposit Accounts and
Securities Accounts included in the Collateral owned or held by or on behalf of
such Grantor.

                    (b) REGISTRATION IN NOMINEE NAME; DENOMINATIONS. Each
Grantor hereby agrees that (i) without limiting Section 8, the Trustee, on
behalf of the Holders, shall have the right (in its sole and absolute
discretion) to hold any Investment Related Property in its own name as pledgee,
the name of its nominee (as pledgee or as sub-agent) or the name of the
applicable Grantor, endorsed or assigned, where applicable, in blank or in favor
of the Trustee (or the Administrative Agent (or Replacement Agent) during the
effectiveness of the Intercreditor Agreement), (ii) at the Trustee's request,
such Grantor will promptly give to the Trustee copies of any material notices or
other communications received by it with respect to any Investment Related
Property registered in its name, and (iii) the Trustee shall at all times have
the right to exchange any certificates, instruments or other documents
representing or evidencing any Investment Related Property owned or held by or
on behalf of such Grantor for certificates, instruments or other documents of
smaller or larger denominations for any purpose consistent with this Security
Agreement.

                    (c) VOTING AND DISTRIBUTIONS.

                        (i) Unless and until an Event of Default shall have
         occurred and be continuing:


                                       16
<PAGE>

                             (A) Each Grantor shall be entitled to exercise any
         and all voting and/or other consensual rights and powers inuring to an
         owner of the Investment Related Property, or any part thereof, for any
         purpose consistent with the terms of this Security Agreement and the
         other Indenture Documents; PROVIDED that such Grantor will not be
         entitled to exercise any such right if the result thereof could
         materially and adversely affect the rights inuring to a holder of the
         Investment Related Property or the rights and remedies of the Trustee
         or any of the Holders under this Security Agreement or any other
         Indenture Document or the ability of the Trustee or any of the Holders
         to exercise the same.

                             (B) Each Grantor shall be entitled to receive,
         retain and use any and all cash dividends, interest and principal paid
         on the Investment Related Property owned or held by it or on its behalf
         to the extent and only to the extent that such cash dividends, interest
         and principal are not prohibited by, and otherwise paid in accordance
         with, the terms and conditions of the Indenture, the other Indenture
         Documents and applicable laws. All non-cash dividends, interest and
         principal, and all dividends, interest and principal paid or payable in
         cash or otherwise in connection with a partial or total liquidation or
         dissolution, return of capital, capital surplus or paid-in surplus, and
         all other distributions (other than distributions referred to in the
         preceding sentence) made on or in respect of the Investment Related
         Property, whether paid or payable in cash or otherwise, whether
         resulting from a subdivision, combination or reclassification of the
         outstanding securities of any issuer of any Investment Related Property
         or received in exchange for any Investment Related Property, or any
         part thereof, or in redemption thereof, or as a result of any merger,
         consolidation, acquisition or other exchange of assets to which such
         issuer may be a party or otherwise, shall be and become part of the
         Collateral, and, if received by such Grantor, shall not be commingled
         with any of its other funds or property but shall be held separate and
         apart therefrom, shall be held in trust for the benefit of the Trustee
         hereunder and shall be forthwith delivered to the Trustee in the same
         form as so received (with any necessary endorsement).

                        (ii) Without limiting the generality of the foregoing,
         upon the occurrence and during the continuance of an Event of Default:

                             (A) All rights of each Grantor to dividends,
         interest or principal that it is authorized to receive pursuant to
         subsection (c)(i)(B) above shall cease, and all such rights shall
         thereupon become vested in the Trustee, which shall have the sole and
         exclusive right and authority to receive and retain such dividends,
         interest or principal, as applicable. All dividends, interest and
         principal received by or on behalf of any Grantor contrary to the
         provisions of this Section shall be held in trust for the benefit of
         the Trustee, shall be segregated from other property or funds of such
         Grantor and shall be forthwith delivered to the Trustee upon demand in
         the same form as so received (with any necessary endorsement). Subject
         to the Intercreditor Agreement while it is in effect, any and all money
         and other property paid over to or received by the Trustee pursuant to
         the provisions of this subsection (c)(ii)(A) shall be retained by the
         Trustee in an account to be established in the name of the Trustee, for
         the benefit of the Holders, upon receipt of such money or other
         property (the "COLLATERAL ACCOUNT") and shall be applied in accordance
         with the provisions of Section 9(b). Subject to the Intercreditor
         Agreement while it is in effect and to the provisions of this
         subsection (c)(ii)(A), such account shall at all times be under the
         sole dominion and control of the Trustee, and the Trustee shall at all
         times have the sole right to make withdrawals therefrom and to exercise
         all rights with respect to the funds and other property from time to
         time therein or credited thereto as set forth in the Indenture
         Documents. After all Events of Default have been cured or waived, the
         Trustee shall, within five Business Days after all such Events of
         Default have been cured or waived, repay to the applicable Grantor all
         cash dividends, interest and principal (without interest) that such
         Grantor would


                                       17
<PAGE>

         otherwise be permitted to retain pursuant to the terms of subsection
         (c)(i)(B) above and which remain in such account.

                             (B) All rights of each Grantor to exercise the
         voting and consensual rights and powers it is entitled to exercise
         pursuant to subsection (c)(i)(A) above, and the obligations of the
         Trustee under subsection (c)(i)(B) above, shall cease, and all such
         rights shall thereupon become vested in the Trustee, which shall have
         the sole and exclusive right and authority to exercise such voting and
         consensual rights and powers, PROVIDED that unless otherwise directed
         by Holders of a majority of the aggregate principal amount of
         outstanding Notes, the Trustee shall have the right from time to time
         following and during the continuance of an Event of Default to permit
         such Grantor to exercise such rights. After all Events of Default have
         been cured or waived, the applicable Grantor will have the right to
         exercise the voting and consensual rights and powers that it would
         otherwise be entitled to exercise pursuant to the terms of subsection
         (c)(i)(A) above.

                    (d) CASH AND INVESTMENT PROPERTY. Each Grantor covenants and
agrees that (i) with respect to each of its Deposit Accounts existing on the
date hereof and set forth in Schedule III hereto, it shall deliver, or cause to
be delivered, to the Trustee on or prior to April 15, 2002, a duly executed
Deposit Account Control Agreement with respect to each such Deposit Account
(other than a Deposit Account that at all times has less than (A) $25,000 on
deposit therein, and (B) when aggregated with all other Deposit Accounts that
are not subject to a Deposit Account Control Agreement in favor of the Trustee,
$100,000 on deposit therein), (ii) it shall not at any time establish or
maintain any other Deposit Account without concurrently therewith delivering to
the Trustee a duly executed Deposit Account Control Agreement with respect to
such Deposit Account, (iii) it shall deposit, or cause to be deposited, no less
frequently than every other Business Day all of its Investment Related Property
(other than Deposit Accounts and Securities Accounts) into one or more such
Deposit Accounts or any Securities Account. Prior to the delivery of a "Notice
of Exclusive Control" under the applicable Deposit Account Control Agreement,
and pursuant to the terms thereof and the other Indenture Documents, each
Deposit Account shall at all times be under the "control" (within the meaning of
Article 9 of the UCC) of the Trustee, and no Grantor shall have access to or any
right to draw upon or withdraw any cash or other funds therefrom, except for
purposes not otherwise prohibited by the Indenture Documents.

         Section 7. FURTHER ASSURANCES.

                    Each Grantor hereby covenants and agrees, at its own cost
and expense, to execute, acknowledge, deliver and/or cause to be duly filed all
such further agreements, instruments and other documents, and take all such
further actions, that the Trustee may from time to time reasonably request to
preserve, protect and perfect (including as a result of any revisions to Article
9 of the UCC in any jurisdiction or the effectiveness thereof or any other
change in applicable law) the Security Interest granted by it and the rights and
remedies created hereby, including the payment of any fees and taxes required in
connection with its execution and delivery of this Security Agreement, the
granting by it of the Security Interest and the filing of any financing
statements or other documents in connection herewith or therewith. In addition,
to the extent permitted by applicable law, each Grantor hereby irrevocably
authorizes the Trustee to file one or more financing or continuation statements,
and amendments thereto, relative to all or any part of the Collateral owned or
held by it or on its behalf without the signature of such Grantor and agrees
that a photographic or other reproduction of this Security Agreement or of a
financing statement signed by such Grantor shall be sufficient as a financing
statement and may be filed as a financing statement in any and all
jurisdictions. Each Grantor hereby further irrevocably authorizes the Trustee to
file a Record or Records, including financing statements, in all jurisdictions
and with all filing offices that the Trustee may determine, in its sole and
absolute discretion, are necessary, advisable or prudent to perfect the Security
Interest granted by it and agrees that such financing statements may


                                       18
<PAGE>

describe the Collateral owned or held by it or on its behalf in the same manner
as described herein or may contain an indication or description of collateral
that describes such Collateral in any other manner that the Trustee may
determine, in its sole and absolute discretion, is necessary, advisable or
prudent to perfect the Security Interest granted by such Grantor, including
describing such property as "all assets" or "all personal property."

         Section 8. TRUSTEE APPOINTED ATTORNEY-IN-FACT.

                    (a) Each Grantor hereby appoints the Trustee as its true and
lawful agent and attorney-in-fact for the purpose of carrying out the provisions
of this Security Agreement and taking any action and executing any instrument
that the Trustee may deem necessary or advisable to accomplish the purposes
hereof, which appointment is irrevocable and coupled with an interest, and
without limiting the generality of the foregoing, the Trustee shall have the
right, with power of substitution for such Grantor and in such Grantor's name or
otherwise, for the use and benefit of the Trustee and the Holders, upon the
occurrence and during the continuance of an Event of Default and at such other
time or times permitted by the Indenture, (i) to receive, endorse, assign and/or
deliver any and all notes, acceptances, checks, drafts, money orders or other
evidences of payment relating to the Collateral owned or held by it or on its
behalf or any part thereof; (ii) to demand, collect, receive payment of, give
receipt for, and give discharges and releases of, any of such Collateral; (iii)
to commence and prosecute any and all suits, actions or proceedings at law or in
equity in any court of competent jurisdiction to collect or otherwise realize on
any of the Collateral owned or held by it or on its behalf or to enforce any
rights in respect of any of such Collateral; (iv) to settle, compromise,
compound, adjust or defend any actions, suits or proceedings relating to any of
such Collateral; (v) to notify, or to require such Grantor to notify, obligors
to make payment directly to the Trustee, and (vi) to use, sell, assign,
transfer, pledge, make any agreement with respect to or otherwise deal with any
of such Collateral, and to do all other acts and things necessary to carry out
the purposes of this Security Agreement, as fully and completely as though the
Trustee were the absolute owner of such Collateral for all purposes; PROVIDED
that nothing herein contained shall be construed as requiring or obligating the
Trustee or any Holder to make any commitment or to make any inquiry as to the
nature or sufficiency of any payment received by the Trustee or any Holder, or
to present or file any claim or notice, or to take any action with respect to
any of the Collateral or the moneys due or to become due in respect thereof or
any property covered thereby, and no action taken or omitted to be taken by the
Trustee with respect to any of the Collateral shall give rise to any defense,
counterclaim or offset in favor of such Grantor or to any claim or action
against the Trustee. The provisions of this Section shall in no event relieve
any Grantor of any of its obligations hereunder or under the other Indenture
Documents with respect to any of the Collateral or impose any obligation on the
Trustee or any Holder to proceed in any particular manner with respect to any of
the Collateral, or in any way limit the exercise by the Trustee or any Holder of
any other or further right that it may have on the date of this Security
Agreement or hereafter, whether hereunder, under any other Indenture Document,
by law or otherwise. Any sale pursuant to the provisions of this paragraph shall
be deemed to conform to the commercially reasonable standards as provided in
Section 9-610(b) of the UCC as in effect in the State of New York or its
equivalent in other jurisdictions (or any successor provision).

         Section 9. REMEDIES UPON DEFAULT.

                    (a) REMEDIES GENERALLY.

                        (i) GENERAL RIGHTS. Upon the occurrence and during the
         continuance of an Event of Default, each Grantor agrees to deliver each
         item of Collateral owned or held by it or on its behalf to the Trustee
         on demand, and it is agreed that the Trustee shall have the right, with
         or without legal process and with or without prior notice or demand for
         performance, to take possession of the Collateral owned or held by it
         or on its behalf and without


                                       19
<PAGE>

         liability for trespass to enter any premises where such Collateral may
         be located for the purpose of taking possession of or removing such
         Collateral and, generally, to exercise any and all rights afforded to a
         secured party under the UCC or other applicable law. Without limiting
         the generality of the foregoing, each Grantor agrees that the Trustee
         shall have the right, subject to the mandatory requirements of
         applicable law, to sell or otherwise dispose of any of the Collateral
         owned or held by or on behalf of such Grantor, at public or private
         sale or at any broker's board or on any securities exchange, for cash,
         upon credit or for future delivery as the Trustee shall deem
         appropriate. In connection with any sale or disposition of the
         Collateral pursuant to this Section 9, each Grantor agrees to promptly
         deliver to the Trustee any documents required under Section 11.10 of
         the Indenture. The Trustee shall be irrevocably authorized at any such
         sale of such Collateral constituting securities (if it deems it
         advisable to do so) to restrict the prospective bidders or purchasers
         to Persons who will represent and agree that they are purchasing such
         Collateral for their own account for investment and not with a view to
         the distribution or sale thereof, and upon consummation of any such
         sale, the Trustee shall have the right to assign, transfer and deliver
         to the purchaser or purchasers thereof the Collateral so sold. Each
         such purchaser at any such sale shall hold the property sold
         absolutely, free from any claim or right on the part of the applicable
         Grantor, and such Grantor hereby waives (to the extent permitted by
         law) all rights of redemption, stay, valuation and appraisal which such
         Grantor now has or may at any time in the future have under any rule of
         law or statute now existing or hereafter enacted.

                        (ii) SALE OF COLLATERAL. The Trustee shall give each
         Grantor ten days' written notice (which such Grantor agrees is
         reasonable notice within the meaning of Sections 9-611 and 9-612 of the
         UCC as in effect in the State of New York or its equivalent in other
         jurisdictions (or any successor provisions)), of the Trustee's
         intention to make any sale of any of the Collateral owned or held by or
         on behalf of such Grantor. Such notice, in the case of a public sale,
         shall state the time and place for such sale and, in the case of a sale
         at a broker's board or on a securities exchange, shall state the board
         or exchange at which such sale is to be made and the day on which such
         Collateral will first be offered for sale at such board or exchange.
         Any such public sale shall be held at such time or times within
         ordinary business hours and at such place or places as the Trustee may
         fix and state in the notice (if any) of such sale. At any such sale,
         the Collateral to be sold may be sold in one lot as an entirety or in
         separate parcels, as the Trustee may (in its sole and absolute
         discretion) determine. The Trustee shall not be obligated to make any
         sale of any Collateral if it shall determine not to do so, regardless
         of the fact that notice of sale of such Collateral shall have been
         given. The Trustee may, without notice or publication, adjourn any
         public or private sale or cause the same to be adjourned from time to
         time by announcement at the time and place fixed for sale, and such
         sale may, without further notice, be made at the time and place to
         which the same was so adjourned. In case any sale of any of the
         Collateral is made on credit or for future delivery, the Collateral so
         sold may be retained by the Trustee until the sale price is paid by the
         purchaser or purchasers thereof, but the Trustee shall not incur any
         liability in case any such purchaser or purchasers shall fail to take
         up and pay for the Collateral so sold and, in case of any such failure,
         such Collateral may be sold again upon like notice. At any public (or,
         to the extent permitted by applicable law, private) sale made pursuant
         to this Section, any Holder may bid for or purchase, free (to the
         extent permitted by applicable law) from any right of redemption, stay,
         valuation or appraisal on the part of such Grantor (all said rights
         being also hereby waived and released to the extent permitted by law),
         any of the Collateral offered for sale and may make payment on account
         thereof by using any claim then due and payable to such Holder from
         such Grantor as a credit against the purchase price, and such Holder
         may, upon compliance with the terms of sale, hold, retain and dispose
         of such property without further accountability to such Grantor
         therefor. For purposes hereof, (i) a written agreement to purchase any
         of the Collateral shall be treated as a sale thereof, (ii) the Trustee
         shall be free to carry out such sale pursuant to such agreement, and
         (iii) no Grantor shall be entitled to


                                       20
<PAGE>

         the return of any of the Collateral subject thereto, notwithstanding
         the fact that after the Trustee shall have entered into such an
         agreement all Events of Default shall have been remedied and the
         Secured Obligations paid in full. As an alternative to exercising the
         power of sale herein conferred upon it, the Trustee may proceed by a
         suit or suits at law or in equity to foreclose upon any of the
         Collateral and to sell any of the Collateral pursuant to a judgment or
         decree of a court or courts having competent jurisdiction or pursuant
         to a proceeding by a court-appointed receiver. Any sale pursuant to the
         provisions of this Section shall be deemed to conform to the
         commercially reasonable standards as provided in Section 9-610(b) of
         the UCC as in effect in the State of New York or its equivalent in
         other jurisdictions (or any successor provisions). Without limiting the
         generality of the foregoing, each Grantor agrees as follows: (A) if the
         proceeds of any sale of the Collateral owned or held by it or on its
         behalf pursuant to this Section are insufficient to pay all the Secured
         Obligations, it shall be liable for the resulting deficiency and the
         fees, charges and disbursements of any counsel employed by the Trustee
         or any Holder to collect such deficiency, (B) it hereby waives any
         claims against the Trustee arising by reason of the fact that the price
         at which any such Collateral may have been sold at any private sale
         pursuant to this Section was less than the price that might have been
         obtained at a public sale, even if the Trustee accepts the first offer
         received and does not offer such Collateral to more than one offeree,
         (C) there is no adequate remedy at law for failure by it to comply with
         the provisions of this Section and that such failure would not be
         adequately compensable in damages, and therefore agrees that its
         agreements in this Section may be specifically enforced, (D) the
         Trustee may sell any such Collateral without giving any warranties as
         to such Collateral, and the Trustee may specifically disclaim any
         warranties of title or the like, and (E) the Trustee shall have no
         obligation to marshall any such Collateral.

                    (b) APPLICATION OF PROCEEDS OF SALE. The Trustee shall apply
the proceeds of any collection or sale of the Collateral, as well as any
Collateral consisting of cash, as follows:

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

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

                    THIRD, to the applicable Grantor, its successors or assigns,
         or as a court of competent jurisdiction may otherwise direct.

                    The Trustee shall have sole and absolute discretion as to
         the time of application of any such proceeds, moneys or balances in
         accordance with this Security Agreement. Upon any sale of the
         Collateral by the Trustee (including pursuant to a power of sale
         granted by statute or under a judicial proceeding), the receipt of the
         purchase money by the Trustee or of the officer making the sale shall
         be a sufficient discharge to the purchaser or purchasers of the
         Collateral so sold and such purchaser or purchasers shall not be
         obligated to see to the application of any part of the purchase money
         paid over to the Trustee or such officer or be answerable in any way
         for the misapplication thereof.

                    (c) INVESTMENT RELATED PROPERTY. In view of the position of
each Grantor in relation to the Investment Related Property, or because of other
current or future circumstances, a question may arise under the Securities Act
of 1933, as now or hereafter in effect, or any similar statute hereafter enacted
analogous in purpose or effect (such Act and any such similar statute as from
time to time in effect being called the "FEDERAL SECURITIES LAWS") with respect
to any disposition of the Investment Related Property permitted hereunder. Each
Grantor understands that compliance with the Federal securities laws might very
strictly limit the course of conduct of the Trustee if the Trustee were to
attempt to dispose of all or any part of the Investment Related Property, and
might also limit the extent to which or the manner in which any subsequent
transferee of any Investment Related Property could dispose of the same.
Similarly, there may be other legal restrictions or limitations affecting the
Trustee in any attempt to dispose of all or part of the Investment Related
Property under applicable Blue Sky or other state securities laws or similar
laws analogous in purpose or effect. Each Grantor recognizes that in light of
such restrictions and limitations the Trustee may, with respect to any sale of
the Investment Related Property, limit the purchasers to those who will agree,
among other things, to acquire such Investment Related Property for their own
account, for investment, and not with a view to the distribution or resale
thereof. Each Grantor acknowledges and agrees that in light of such restrictions
and limitations, the Trustee, in its sole and absolute discretion, (i) may
proceed to make such a sale whether or not a registration statement for the
purpose of registering such Investment Related Property, or any part thereof,
shall have been filed under the Federal securities laws and (ii) may approach
and negotiate with a single potential purchaser to effect such sale. Each
Grantor acknowledges and agrees that any such sale might result in prices and
other terms less favorable to the seller than if such sale were a public sale
without such restrictions. In the event of any such sale, the Trustee shall
incur no responsibility or liability for selling all or any part of the
Investment Related Property at a price that the Trustee, in its sole and
absolute discretion, may in good faith deem reasonable under the circumstances,
notwithstanding the possibility that a substantially higher price might have
been realized if the sale were deferred until after registration as aforesaid or
if more than a single purchaser were approached. The provisions of this Section
will apply notwithstanding the existence of a public or private market upon
which the quotations or sales prices may exceed substantially the price at which
the Trustee sells any such Investment Related Property.

                    (d) REGISTRATION, ETC. Each Grantor agrees that, upon the
occurrence and during the continuance of an Event of Default, if for any reason
the Trustee desires to sell any of the Investment Related Property owned or held
by or on behalf of such Grantor at a public sale, it will, at any time and from
time to time, upon the written request of the Trustee, use its best efforts to
take or to cause, where applicable, the issuer of such Investment Related
Property to take such action and prepare, distribute and/or file such documents,
as are required or advisable in the reasonable opinion of counsel for the
Trustee to permit the public sale of such Investment Related Property. Each
Grantor further agrees to indemnify, defend and hold harmless the Trustee, each
Holder, any underwriter and their respective officers, directors, affiliates and
controlling Persons from and against all loss, liability, expenses, costs of
counsel (including reasonable fees and expenses of legal counsel), and claims
(including the costs of investigation) that they may incur, insofar as such
loss, liability, expense or claim, as applicable, relates to such Grantor or any
of its property, and arises out of or is based upon any alleged untrue statement
of a material fact contained in any prospectus (or any amendment or supplement
thereto) or in any notification or offering circular, or arises out of or is
based upon any alleged omission to state a material fact required to be stated
therein or necessary to make the statements in any thereof not misleading,
except insofar as the same may have been caused by any untrue statement or
omission based upon information furnished in writing to such Grantor or the
issuer of such Investment Related Property, as applicable, by the Trustee
expressly for use therein. Each Grantor further agrees, upon such written
request referred to above, to use its best efforts to qualify, file or register,
or cause, where applicable, the issuer of such Investment Related Property to
qualify, file or register, any of the Investment Related Property owned or held
by or on behalf of such Grantor under the Blue Sky or other securities laws of
such states as may be requested by the


                                       22
<PAGE>

Trustee and keep effective, or cause to be kept effective, all such
qualifications, filings or registrations. Each Grantor will bear all costs and
expenses of carrying out its obligations under this Section. Each Grantor
acknowledges that there is no adequate remedy at law for failure by it to comply
with the provisions of this Section and that such failure would not be
adequately compensable in damages, and therefore agrees that its agreements
contained in this Section may be specifically enforced.

         Section 10. GRANT OF LICENSE TO USE INTELLECTUAL PROPERTY.

                     For the purpose of enabling the Trustee to exercise rights
and remedies under Section 9, and under this Section, at such time as the
Trustee shall be lawfully entitled to exercise such rights and remedies, each
Grantor hereby grants to the Trustee an irrevocable, non-exclusive license
(exercisable without payment of royalty or other compensation to the Grantors)
to use, license or sub-license any of the Collateral consisting of Intellectual
Property now owned or hereafter acquired by such Grantor, and wherever the same
may be located, and including in such license reasonable access to all media in
which any of the licensed items may be recorded or stored and to all computer
software and programs used for the compilation or printout thereof (subject, in
the case of Trademarks, to sufficient rights to quality control and inspection
in favor of the Grantor to avoid the risk of invalidation of said Trademarks).
The use of such license by the Trustee shall be exercised, at the option of the
Trustee, upon the occurrence and during the continuation of an Event of Default;
PROVIDED that any license, sub-license or other transaction entered into by the
Trustee in accordance herewith shall be binding upon the Grantors
notwithstanding any subsequent cure of an Event of Default. Any royalties and
other payments received by the Trustee shall be applied in accordance with
Section 9(b).

         Section 11. REIMBURSEMENT OF TRUSTEE.

                     Each Grantor agrees, jointly with the other Grantors and
severally, to pay to the Trustee the amount of any and all reasonable
out-of-pocket expenses, including the fees, other charges and disbursements of
counsel (including allocated costs of internal counsel) and of any experts or
agents, that the Trustee may incur in connection with (a) the administration of
this Security Agreement relating to such Grantor or any of its property and any
consent, amendment, waiver or other modification to this Security Agreement, (b)
the creation and perfection of Liens in favor of Trustee for the benefit of
Holders, including filing and recording fees, expenses and taxes, search fees,
and the reasonable fees, expenses and disbursements of any counsel providing any
opinions in respect of the Collateral or the Liens created pursuant to the
Collateral Agreements, (c) the custody or preservation of, or the sale of,
collection from, or other realization upon, any of the Collateral owned or held
by or on behalf of such Grantor, (d) the exercise, enforcement or protection of
any of the rights of the Trustee hereunder relating to such Grantor or any of
its property, including any costs of settlement incurred by the Trustee after
the occurrence of an Event of Default, (e) any refinancing or restructuring of
the credit arrangements pursuant to the Indenture, including a "work-out," or
pursuant to any insolvency or bankruptcy cases or proceedings, or (f) the
failure by such Grantor to perform or observe any of the provisions hereof.
Without limitation of its indemnification obligations under the other Indenture
Documents, each of the Grantors agrees, jointly with the other Grantors and
severally, to indemnify the Trustee and the Holders against, and hold the
Trustee and each Holder harmless from, any and all losses, claims, damages,
liabilities and related out-of-pocket expenses, including reasonable counsel
fees (including allocated costs of internal counsel), other charges and
disbursements, incurred by or asserted against the Trustee or any Holder arising
out of, in any way connected with, or as a result of (a) the execution or
delivery by such Grantor of this Security Agreement or any other Indenture
Document or any agreement or instrument contemplated hereby or thereby, or the
performance by such Grantor of its obligations under the Indenture Documents and
the other transactions contemplated thereby or (b) any claim, litigation,
investigation or proceeding relating to any of the foregoing, whether or not the
Trustee or any Holder is a party thereto, PROVIDED that such indemnity shall
not, as to the Trustee or any Holder, be available to the


                                       23
<PAGE>

extent that such losses, claims, damages, liabilities or related expenses are
determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of the
Trustee or such Holder, respectively. Any amounts payable as provided hereunder
shall be additional Secured Obligations secured hereby and by the other Security
Documents. The provisions of this Section shall remain operative and in full
force and effect regardless of the termination of this Security Agreement or any
other Indenture Document, the consummation of the transactions contemplated
hereby or thereby, the repayment of any of the Secured Obligations, the
invalidity or unenforceability of any term or provision of this Security
Agreement or any other Indenture Document or any investigation made by or on
behalf of the Trustee or any Holder. All amounts due under this Section shall be
payable within ten days of written demand therefor and shall bear interest at
the rate of 11-7/8% per annum.

         Section 12. WAIVERS; AMENDMENT.

                     No failure or delay of the Trustee in exercising any power
or right hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Trustee and the Holders hereunder and under the other
Indenture Documents are cumulative and are not exclusive of any rights or
remedies that they would otherwise have. No waiver of any provision of this
Security Agreement or any other Indenture Document or consent to any departure
by any Grantor therefrom shall in any event be effective unless the same shall
be permitted by this Section, and then such waiver or consent shall be effective
only in the specific instance and for the purpose for which given. No notice or
demand on any Grantor in any case shall entitle such Grantor to any other or
further notice or demand in similar or other circumstances. Neither this
Security Agreement nor any provision hereof may be waived, amended, supplemented
or otherwise modified, or any departure therefrom consented to, except pursuant
to an agreement or agreements in writing entered into by, between or among the
Trustee and the Grantor or Grantors with respect to which such waiver,
amendment, other modification or consent is to apply, subject to any consent
required in accordance with Article IX of the Indenture.

         Section 13. SECURITY INTEREST ABSOLUTE.

                     All rights of the Trustee hereunder, the Security Interest
and all obligations of each Grantor hereunder shall be absolute and
unconditional irrespective of (i) any lack of validity or enforceability of the
Indenture, any other Indenture Document, any agreement with respect to any of
the Secured Obligations, or any other agreement or instrument relating to any of
the foregoing, (ii) 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 waiver,
amendment, supplement or other modification of, or any consent to any departure
from, the Indenture, any other Indenture Document or any other agreement or
instrument relating to any of the foregoing, (iii) any exchange, release or
non-perfection of any Lien on any other collateral, or any release or waiver,
amendment, supplement or other modification of, or consent under, or departure
from, any guaranty, securing or guaranteeing all or any of the Secured
Obligations, or (iv) any other circumstance that might otherwise constitute a
defense available to, or a discharge of, any Grantor in respect of the Secured
Obligations or in respect of this Security Agreement or any other Indenture
Document.

         Section 14. TERMINATION; RELEASE.

                     This Security Agreement and the Security Interest shall
terminate when all the Secured Obligations have been finally and indefeasibly
paid in full in cash. In connection with the termination of the Security
Interest pursuant to this Section or any release of any Collateral permitted by



                                       24
<PAGE>

Sections 11.9 and 11.10 of the Indenture, the Trustee shall execute and deliver
to the applicable Grantor, at the cost and expense of such Grantor, all UCC
termination statements and similar documents that such Grantor may reasonably
request to evidence such termination or release. Any execution and delivery of
documents pursuant to this Section shall be without recourse to or warranty by
the Trustee or any Holder. Notwithstanding the foregoing, this Security
Agreement shall continue to be effective or shall be reinstated, as the case may
be, if at any time any amount received by a Holder in respect of the Secured
Obligations is rescinded or must otherwise be restored or returned by such
Holder upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of any Grantor or upon the appointment of any intervenor or
conservator of, or trustee or similar official for, any Grantor or any
substantial part of its properties, or otherwise, all as though such payments
had not been made.

         Section 15. ADDITIONAL GRANTORS.

                     Upon execution and delivery after the date hereof by the
Trustee and a Subsidiary of a Supplement, such Subsidiary, shall become a
Grantor hereunder with the same force and effect as if originally named as a
Grantor herein (each an "ADDITIONAL GRANTOR"). The execution and delivery of any
Supplement shall not require the consent of any other Grantor hereunder. The
rights and obligations of each Grantor hereunder and under the Indenture
Documents shall remain in full force and effect notwithstanding the addition of
any Additional Grantor as a party to this Security Agreement.

         Section 16. NOTICES.

                     All communications and notices hereunder shall be in
writing and given as provided in Section 12.2 of the Indenture. All
communications and notices hereunder to the Trustee shall be given to it at its
address for notices set forth in such Section, and all communications and
notices hereunder to the Company and any other Grantor shall be given to it at
its address for notices set forth on Schedule I hereto or to the applicable
Supplement, with, in the case of any Grantor other than the Company, a copy to
the Company.

         Section 17. BINDING EFFECT; SEVERAL AGREEMENT; ASSIGNMENTS.

                     Whenever in this Security Agreement any of the parties
hereto is referred to, such reference shall be deemed to include the successors
and assigns of such party, and all covenants, promises and agreements by or on
behalf of any Grantor that are contained in this Security Agreement shall bind
and inure to the benefit of each party hereto and its successors and assigns.
This Security Agreement shall become effective as to any Grantor when a
counterpart hereof executed on behalf of such Grantor shall have been delivered
to the Trustee and a counterpart hereof shall have been executed on behalf of
the Trustee, and thereafter shall be binding upon such Grantor and the Trustee
and their respective successors and assigns, and shall inure to the benefit of
such Grantor, the Trustee and the Holders, and their respective successors and
assigns, except that no Grantor shall have the right to assign its rights or
obligations hereunder or any interest herein or in any of the Collateral (and
any such attempted assignment shall be void), except as expressly contemplated
by this Security Agreement or the other Indenture Documents. This Security
Agreement shall be construed as a separate agreement with respect to each of the
Grantors and may be amended, supplemented, waived or otherwise modified or
released in accordance herewith and in accordance with the Indenture with
respect to any Grantor without the approval of any other Grantor and without
affecting the obligations of any other Grantor hereunder.

         Section 18. SURVIVAL OF AGREEMENT; SEVERABILITY; ENTIRE AGREEMENT.

                     All covenants, agreements, representations and warranties
made by the Grantors herein and in the certificates or other instruments
prepared or delivered in connection with or pursuant to


                                       25
<PAGE>

this Security Agreement or any other Indenture Document shall be considered to
have been relied upon by the Trustee and the Holders and shall survive the
execution and delivery of any Indenture Document, regardless of any
investigation made by the Holders or on their behalf, and shall continue in full
force and effect until this Security Agreement shall terminate. In the event any
one or more of the provisions contained in this Security Agreement or in any
other Indenture Document should be held invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions
contained herein or therein shall not in any way be affected or impaired thereby
(it being understood that the invalidity of a particular provision in a
particular jurisdiction shall not in and of itself affect the validity of such
provision in any other jurisdiction). This Security Agreement and the other
Indenture Documents embody the entire agreement and understanding among the
Grantors and the Trustee and supersede all prior agreements and understandings
between such parties relating to the subject matter hereof and thereof.

         Section 19. GOVERNING LAW.

                     THIS SECURITY AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         Section 20. COUNTERPARTS.

                     This Security Agreement may be executed in counterparts
(and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which, when taken together, shall constitute
but one contract (subject to Section 17), and shall become effective as provided
in Section 17. Delivery of an executed counterpart of this Security Agreement by
facsimile transmission shall be as effective as delivery of a manually executed
counterpart of this Security Agreement.

         Section 21. HEADINGS.

                     Section and Section headings and the Table of Contents used
herein are for convenience of reference only, are not part of this Security
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Security Agreement.

         Section 22. JURISDICTION; VENUE; CONSENT TO SERVICE OF PROCESS.

                     Each Grantor hereby irrevocably and unconditionally
submits, for itself and its property, to the nonexclusive jurisdiction of any
New York State court or Federal court of the United States of America sitting in
New York City, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Security Agreement or the other
Indenture Documents, or for recognition or enforcement of any judgment, and each
of the parties hereto hereby irrevocably and unconditionally agrees that, to the
extent permitted by applicable law, all claims in respect of any such action or
proceeding may be heard and determined in such New York State court or, to the
extent permitted by applicable law, in such Federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Security Agreement shall
affect any right that the Trustee or any Holder may otherwise have to bring any
action or proceeding relating to this Security Agreement or the other Indenture
Documents against such Grantor or any of its property in the courts of any
jurisdiction. Each Grantor hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection that it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Security Agreement or the other Indenture
Documents in any foregoing court referred to in this Section. Each of the
parties hereto hereby


                                       26
<PAGE>

irrevocably waives, to the fullest extent permitted by applicable law, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court. Each party hereto irrevocably consents to service of process
in the manner provided for notices in Section 16. Nothing in this Security
Agreement will affect the right of any party hereto to serve process in any
other manner permitted by law.

         Section 23. WAIVER OF JURY TRIAL.

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

         Section 24. NO DUTY ON THE PART OF THE TRUSTEE; STANDARD OF CARE.

                     The powers conferred on the Trustee hereunder are solely to
protect the interests of the Holders in the Collateral and shall not impose any
duty upon the Trustee to exercise any such powers. The Trustee and the Holders
shall be accountable only for amounts that they actually receive as a result of
the exercise of such powers, and neither they nor any of their officers,
directors, employees or agents shall be responsible to any Grantor for any act
or failure to act hereunder, except for their own gross negligence or willful
misconduct. Except for the exercise of reasonable care in the custody of any
Collateral in its possession and the accounting for moneys actually received by
it hereunder, the Trustee 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. The Trustee shall be deemed to have
exercised reasonable care in the custody and preservation of Collateral in its
possession if such Collateral is accorded treatment substantially equal to that
which the Trustee accords its own property. Neither the Trustee nor any of its
directors, officers, employees 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 any Grantor or otherwise.

         Section 25. INDENTURE CONTROLS.

                     All terms, covenants, conditions, provisions and
requirements of the Indenture, including Article VII thereof, are incorporated
by reference in this Security Agreement. In the event of any conflict or
inconsistency between the provisions of this Security Agreement and those of the

                        TO PLEDGE AND SECURITY AGREEMENT

                               FORM OF SUPPLEMENT
                               ------------------

         SUPPLEMENT NO. __, dated as of ______________, to the PLEDGE AND
SECURITY AGREEMENT, dated as of March 28, 2002, among PENTON MEDIA, INC, a
Delaware corporation (the "COMPANY"), the subsidiaries of the Company party
thereto, and U.S. BANK NATIONAL ASSOCIATION, as trustee (the "TRUSTEE") under
the Indenture referred to in the next paragraph (as amended, restated, extended,
supplemented or otherwise modified from time to time, the "SECURITY AGREEMENT").

                  Reference is made to the Indenture, dated as of March 28,
2002, among the Company, the subsidiaries of the Company party thereto, and the
Trustee (as amended, restated, extended, supplemented or otherwise modified from
time to time, the "INDENTURE"). Capitalized terms used herein and not defined
herein shall have the meanings assigned to such terms in the Indenture and the
Security Agreement.

                  The Grantors have entered into the Security Agreement in
connection with the issuance by the Company of 11-7/8% Senior Secured Notes Due
2007. Section 15 of the Security Agreement provides that additional Subsidiaries
may become Grantors under the Security Agreement by execution and delivery of an
instrument in the form of this Supplement. The undersigned Subsidiary (the "NEW
GRANTOR") is executing this Supplement to become a Grantor under the Security
Agreement in accordance with the requirements of the Indenture.

                  For good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Trustee and the New Grantor
hereby agree as follows:

         Section 1. In accordance with Section 15 of the Security Agreement, the
New Grantor by its signature below becomes a Grantor under the Security
Agreement with the same force and effect as if originally named therein as a
Grantor, and the New Grantor hereby agrees to, and to be bound by, all the terms
and provisions of the Security Agreement applicable to it as a Grantor
thereunder. In furtherance of the foregoing, the New Grantor, as security for
the payment and performance in full of the Secured Obligations, does hereby
create and grant to the Trustee (and its successors and assigns), for the
benefit of the Secured Parties (and their successors and assigns), a security
interest in and lien on all of the New Grantor's right, title and interest in
and to the Collateral (as defined in the Security Agreement) of the New Grantor.
Each reference to a "Grantor" in the Security Agreement shall be deemed to
include the New Grantor. The Security Agreement is hereby incorporated herein by
reference.

         Section 2. The New Grantor represents and warrants to the Trustee and
the other Secured Parties that (i) this Supplement has been duly authorized,
executed and delivered by it and constitutes its legal, valid and binding
obligation, enforceable against it in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting creditors' rights generally, (ii) set forth on the Schedules
attached hereto are true and complete schedules of all of the information that
would have been required to have been delivered by or on behalf of the New
Grantor pursuant to the Security Agreement and the Schedules thereto if the New
Grantor had been originally named in the Security Agreement, and (iii) the
representations and warranties made by it as a Grantor under the Security
Agreement are true and correct on and as of the date hereof giving effect to the
applicable information referred to in clause (ii) of this Section.

         Section 3. This Supplement may be executed in counterparts (and by each
party hereto on a

<PAGE>

different counterpart), each of which shall constitute an original, but both of
which, when taken together, shall constitute but one contract. This Supplement
shall become effective when the Trustee shall have received counterparts of this
Supplement that, when taken together, bear the signatures of the New Grantor and
the Trustee. Delivery of an executed counterpart of this Supplement by facsimile
transmission shall be as effective as delivery of a manually executed
counterpart of this Supplement.

         Section 4. Except as expressly supplemented hereby, the Security
Agreement shall remain in full force and effect.

         Section 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         Section 6. In the event any one or more of the provisions contained in
this Supplement should be held invalid, illegal or unenforceable in any respect,
the validity, legality and enforceability of the remaining provisions contained
herein and in the Security Agreement shall not in any way be affected or
impaired thereby (it being understood that the invalidity of a particular
provision in a particular jurisdiction shall not in and of itself affect the
validity of such provision in any other jurisdiction). The parties hereto shall
endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

         Section 7. All communications and notices hereunder shall be in writing
and given as provided in Section 16 of the Security Agreement. All
communications and notices hereunder to the New Grantor shall be given to it at
the address set forth in the applicable Schedule hereto, with a copy to the
Company.

         Section 8. The New Grantor agrees to reimburse the Trustee for its
out-of-pocket expenses in connection with this Supplement, including the fees,
disbursements and other charges of counsel for the Trustee.
