covenants and agrees that:

                              (1) except as provided in the next sentence or as
otherwise expressly permitted under the Secured Debt Documents, in the event
such Grantor receives any dividends, interest or distributions on any Investment
Property, or any securities or other property upon the merger, consolidation,
liquidation or dissolution of any issuer of any Investment Property, in each
case constituting Article 9 Collateral, then (A) such dividends, interest or
distributions and securities or other property shall be included in the Article
9 Collateral without further action and (B) such Grantor shall take all steps,
if any, reasonably necessary to ensure the validity, perfection, priority and,
if applicable, control of the Collateral Agent over any such Investment Property
with a value in excess of $100,000 (including, without limitation, delivery
thereof to the Collateral Agent) and pending any such action such Grantor shall
be deemed to hold such dividends, interest, distributions, securities or other
property in trust for the benefit of the Collateral Agent and shall be
segregated from all other property of such Grantor.

                              (2) If any issuer of any Investment Property is
located in a jurisdiction outside of the United States, each Grantor shall take
such additional actions, including, without limitation, causing the issuer to
register the pledge on its books and records or making such filings or
recordings, in each case as may be reasonably necessary, under the laws of such
issuer's jurisdiction to insure the validity, perfection and priority of the
security interest of the Collateral Agent. Upon the occurrence of an Event of
Default and written notice from the Collateral Agent to the applicable Grantor
(provided that if an Insolvency Proceeding shall have occurred with respect to
such Grantor, such written notice shall not be required and shall be deemed to
have been received by such Grantor upon the occurrence of such Event of
Default), the Collateral Agent shall have the right to transfer all or any
portion of the Investment Property to its name or the name of its nominee or
agent. In addition, the Collateral Agent shall have the right at any time,
without notice to any Grantor, to exchange any certificates or instruments
representing any Investment Property for certificates or instruments of smaller
or larger denominations.

                        (ii) Delivery and Control. Each Grantor, with respect to
any Investment Property that is represented by a certificate or that is an
"instrument" (other than any Investment Property credited to a Securities
Account) and constitutes Article 9 Collateral, shall cause such certificate or
instrument to be delivered to the Collateral Agent, indorsed in

<PAGE>

blank by an "effective indorsement" (as defined in Section 8-107 of the UCC).
With respect to any Investment Property constituting Article 9 Collateral that
is an "uncertificated security" for purposes of the UCC (other than any
"uncertificated securities" credited to a Securities Account), it shall cause
the issuer of such uncertificated security to register the Collateral Agent as
the registered owner thereof on the books and records of the issuer.

                        (iii) Voting and Distributions.

                              (1) Unless an Event of Default shall have occurred
and be continuing and written notice shall have been provided by the Collateral
Agent to the applicable Grantor (provided that if an Insolvency Proceeding shall
have occurred with respect to such Grantor, such written notice shall not be
required and shall be deemed to have been received by such Grantor upon the
occurrence of such Event of Default), each Grantor shall be entitled to exercise
all Voting and other rights with respect to any Investment Property constituting
Article 9 Collateral; provided, however, that no vote shall be cast, right
exercised or other action taken which would result in any violation of any
provision of this Agreement or any other Secured Debt Document. Upon the
occurrence and during the continuation of an Event of Default and upon written
notice from the Collateral Agent to such Grantor (provided that if an Insolvency
Proceeding shall have occurred with respect to such Grantor, such written notice
shall not be required and shall be deemed to have been received by such Grantor
upon the occurrence of such Event of Default), all voting and other rights of
such Grantor with respect to any Investment Property constituting Article 9
Collateral which such Grantor would otherwise be entitled to exercise pursuant
to the terms of this Agreement or otherwise shall cease, and all such rights
shall be vested in the Collateral Agent which shall thereupon have the sole
right to exercise such rights. After all Events of Default have been cured or
waived and the Company has delivered to the Collateral Agent a certificate to
that effect, the Grantors' rights under this Section 4.3(b)(iii)(1) shall be
reinstated.

                              (2) Unless an Event of Default shall have occurred
and be continuing and written notice shall have been provided by the Collateral
Agent to the applicable Grantor (provided that if an Insolvency Proceeding shall
have occurred with respect to such Grantor, such written notice shall not be
required and shall be deemed to have been received by such Grantor upon the
occurrence of such Event of Default), each Grantor shall be entitled to receive
and retain any and all dividends, interest, principal and other distributions
paid on or distributed in respect of any Investment Property constituting
Article 9 Collateral to the extent and only to the extent that all such
dividends, interest, principal and other distributions are permitted by, and
otherwise paid or distributed in accordance with, the terms and conditions of
the Secured Debt Documents. Upon the occurrence and during the continuation of
an Event of Default and upon written notice from the Collateral Agent to such
Grantor (provided that if an Insolvency Proceeding shall have occurred with
respect to such Grantor, such written notice shall not be required and shall be
deemed to have been received by such Grantor upon the occurrence of such Event
of Default), all rights of such Grantor to the dividends, interest, principal
and other distributions shall cease and all such rights shall be vested in the
Collateral Agent which shall thereupon have the sole right to receive such
distributions. After all Events of Defaults have been cured or waived and the
Company has delivered to the Collateral Agent a certificate to that effect, the
Grantors' rights under this Section 4.3(b)(iii)(2) shall be reinstated. All
distributions and other amounts which are received by any Grantor contrary to
the provisions of this

<PAGE>

Agreement shall be received in trust for the benefit of the Collateral Agent,
shall be segregated from other funds of such Grantor and shall be forthwith paid
over to the Collateral Agent as Article 9 Collateral in the same form as so
received (with any necessary endorsement requested by Collateral Agent).

                              (3) In order to permit the Collateral Agent to
exercise the voting and other consensual rights which it may be entitled to
exercise pursuant hereto and to receive all dividends and other distributions
which it may be entitled to receive hereunder: (A) each Grantor shall promptly
execute and deliver (or cause to be executed and delivered) to the Collateral
Agent all proxies, dividend payment orders and other instruments as the
Collateral Agent may from time to time reasonably request and (B) each Grantor
acknowledges that the Collateral Agent may utilize the power of attorney set
forth in Article VI.

                  (a) the Collateral Agent may at any time notify, or require
any Grantor to so notify, the counterparty on any contract, instrument or other
agreement included in the Article 9 Collateral of the security interest of the
Collateral Agent therein; and

                  (b) with respect to any Non-Assignable Contract that is a
Third Party Project Document to which it is a party and that constitutes Article
9 Collateral, each Grantor shall, unless the relevant restrictions on transfer
are overridden by Section 9-406 of the UCC, within 30 days of the date hereof
with respect to any such Non-Assignable Contract in effect on the date hereof
and within thirty (30) days after entering into any such Non-Assignable Contract
after the Closing Date, request the consent of the counterparty or
counterparties to such Non-Assignable Contract pursuant to the terms of such
Non-Assignable Contract or applicable law to the assignment or granting of a
security interest in such Non-Assignable Contract to Collateral Agent and use
commercially reasonable efforts to obtain such consent as soon as practicable
thereafter.

      Section 4.5 Letter of Credit Rights. Each Grantor hereby represents and
warrants on the Closing Date that it has no Letter of Credit Rights other than
Letter of Credit Rights consisting of Supporting Obligations.

                                   ARTICLE V.
               ACCESS; RIGHT OF INSPECTION AND FURTHER ASSURANCES

      Section 5.1 Access; Right of Inspection. The Collateral Agent and its
representatives shall, during normal business hours and under reasonable
procedures, (a) have full and free access to all books, correspondence and
records of each Grantor reasonably related to the Article 9 Collateral, and (b)
have the right to examine the same, take extracts therefrom and make photocopies
thereof. Each Grantor agrees to render to the Collateral Agent, at such
Grantor's cost and expense, such clerical and other assistance as may be
reasonably requested with regard to the foregoing. The Collateral Agent and its
representatives shall also have the right, during normal business hours and
under reasonable procedures, to enter the premises of any Grantor for the
purpose of inspecting the Article 9 Collateral and observing its use and
condition.

<PAGE>

      Section 5.2 Further Assurances.

                  (a) Each Grantor agrees that from time to time, at its own
expense it shall promptly Authenticate, execute and deliver all further
instruments and documents, and take all further action, as may be reasonably
requested by the Collateral Agent, in order to create and/or maintain the
validity, perfection or priority of 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 Article 9
Collateral. Without limiting the generality of the foregoing, each Grantor shall
file such financing or continuation statements, or amendments thereto, and
execute and deliver such other agreements, instruments, endorsements, powers of
attorney or notices, as the Collateral Agent may reasonably request, in order to
perfect and preserve the security interests granted or purported to be granted
hereby.

                  (b) Each Grantor hereby authorizes the filing of any financing
statements or continuation statements, and amendments to financing statements,
or any similar document in any jurisdictions and with any filing offices as the
Collateral Agent may determine, in its sole discretion, are necessary or
advisable to perfect or otherwise protect the security interest granted to the
Collateral Agent herein. Such financing statements may describe the Article 9
Collateral in the same manner as described herein or may contain an indication
or description of collateral that describes such property in any other manner as
the Collateral Agent may determine, in its sole discretion, is necessary,
advisable or prudent to ensure the perfection of the security interest in the
Article 9 Collateral granted to the Collateral Agent herein, including, without
limitation, describing such property as "all assets" or "all personal property,
whether now owned or hereafter acquired".

                                   ARTICLE VI.
                   COLLATERAL AGENT APPOINTED ATTORNEY-IN-FACT

            Each Grantor hereby irrevocably appoints the Collateral Agent (such
appointment being coupled with an interest) as such Grantor's attorney-in-fact,
with full authority in the place and stead of such Grantor and in the name of
such Grantor, the Collateral Agent or otherwise, from time to time in the
Collateral Agent's discretion to take any action and to execute any instrument
that the Collateral Agent may deem reasonably necessary to accomplish the
purposes of this Agreement, including, without limitation, the following, upon
the occurrence and during the continuation of any Event of Default (but, except
as otherwise expressly provided herein, not in any other circumstances):

            (a) to obtain and adjust insurance required to be maintained by such
Grantor or paid to the Collateral Agent pursuant to the Secured Debt Documents;

            (b) to ask for, demand, collect, sue for, recover, compound, receive
and give acquittance and receipts for moneys due and to become due under or in
respect of any of the Article 9 Collateral;

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

<PAGE>

            (d) to file any claims or take any action or institute any
proceedings that the Collateral Agent may deem necessary or desirable for the
collection of any of the Article 9 Collateral or otherwise to enforce the rights
of the Collateral Agent with respect to any of the Article 9 Collateral;

            (e) to prepare, sign, and file for recordation in any intellectual
property registry, appropriate evidence of the lien and security interest
granted herein in the Intellectual Property in the name of such Grantor as
assignor;

            (f) to take or cause to be taken all actions necessary to perform or
comply or cause performance or compliance with the terms of this Agreement,
including, without limitation, access to pay or discharge taxes or Liens (other
than Permitted Liens) levied or placed upon or threatened against the Article 9
Collateral, the legality or validity thereof and the amounts necessary to
discharge the same to be determined by the Collateral Agent in its sole
discretion, any such payments made by the Collateral Agent to become obligations
of such Grantor to the Collateral Agent, due and payable immediately without
demand;

            (g) to exercise remedies, generally to sell, transfer, lease,
license, pledge, make any agreement with respect to or otherwise deal with any
of the Article 9 Collateral as fully and completely as though the Collateral
Agent were the absolute owner thereof for all purposes; and

            (h) to do, at the Collateral Agent's option and such Grantor's
expense, at any time or from time to time, all acts and things that the
Collateral Agent deems reasonably necessary to protect, preserve or realize upon
the Article 9 Collateral and the Collateral Agent's security interest therein in
order to effect the intent of this Agreement, all as fully and effectively as
such Grantor might do.

                                  ARTICLE VII.
                                    REMEDIES

      Section 7.1 Generally.

                  (a) If any Event of Default shall have occurred and be
continuing, the Collateral Agent may exercise in respect of the Collateral, in
addition to all other rights and remedies provided for herein or otherwise
available to it at law or in equity, all the rights and remedies of the
Collateral Agent available to it under the UCC to collect, enforce or satisfy
any Secured Obligations then owing, whether by acceleration or otherwise, and
also may pursue any of the following separately, successively or simultaneously,
in each case subject to and in accordance with the Collateral Trust Agreement:

                        (i) notify, or require the applicable Grantor to notify,
any counterparty to a contract, instrument or other agreement to make all
payments under such agreement directly to the Collateral Agent;

                        (ii) require any Grantor to, and each Grantor hereby
agrees that it shall at its expense and promptly 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

<PAGE>

Collateral Agent at a place to be designated by the Collateral Agent that is
reasonably convenient to both parties;

                        (iii) enter onto the property where any Article 9
Collateral is located and take possession thereof with or without judicial
process;

                        (iv) prior to the disposition of the Article 9
Collateral, store, process, repair or recondition the Article 9 Collateral or
otherwise prepare the Article 9 Collateral for disposition in any manner to the
extent the Collateral Agent deems appropriate; and

                        (v) without notice except as specified below or under
the UCC, sell, assign, lease, license (on an exclusive or nonexclusive basis) or
otherwise dispose of the Article 9 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, at such time or times and
at such price or prices and upon such other terms as the Collateral Agent may
deem commercially reasonable.

                  (b) The Collateral Agent or any Secured Party may be the
purchaser of any or all of the Article 9 Collateral at any public or private
sale (to the extent the portion of the Article 9 Collateral being privately sold
is of a kind that is customarily sold on a recognized market or the subject of
widely distributed standard price quotations) in accordance with the UCC and the
Collateral Agent, as collateral agent for and representative of the Secured
Parties, shall be entitled, for the purpose of bidding and making settlement or
payment of the purchase price for all or any portion of the Article, Collateral
sold at any such sale made in accordance with the UCC, to use and apply any of
the Secured Obligations as a credit on account of the purchase price for any
Article 9 Collateral payable by the Collateral Agent at such sale. Each
purchaser at any such sale shall hold the property sold absolutely free from any
claim or right on the part of any Grantor, and each Grantor hereby waives (to
the extent permitted by applicable law) all rights of redemption, stay and/or
appraisal which it now has or may at any time in the future have under any rule
of law or statute now existing or hereafter enacted. Each Grantor agrees that,
to the extent notice of sale shall be required by law, at least ten (10) days
notice to such Grantor of the time and place of any public sale or the time
after which any private sale is to be made shall constitute reasonable
notification. The Collateral Agent shall not be obligated to make any sale of
Article 9 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. Each
Grantor agrees that it would not be commercially unreasonable for the Collateral
Agent to dispose of the Article 9 Collateral or any portion thereof by using
Internet sites that provide for the auction of assets of the types included in
the Article 9 Collateral or that have the reasonable capability of doing so, or
that match buyers and sellers of assets. Each Grantor hereby waives any claims
against the Collateral Agent arising by reason of the fact that the price at
which any Article 9 Collateral may have been sold at such a private sale was
less than the price which might have been obtained at a public sale, even if the
Collateral Agent accepts the first offer received and does not offer such
Article 9 Collateral to more than one offeree. Subject to Section 12.15 of this
Agreement, if the proceeds of any sale or other disposition of the Article 9
Collateral are insufficient to pay all the Secured Obligations, each

<PAGE>

Grantor shall be liable for the deficiency and the fees of any attorneys
employed by the Collateral Agent to collect such deficiency. Each Grantor
further agrees that a breach of any of the covenants contained in this Section
will cause irreparable injury to the Collateral Agent, that the Collateral Agent
has no adequate remedy at law in respect of such breach and, as a consequence,
that each and every covenant contained in this Section shall be specifically
enforceable against such Grantor, and such Grantor hereby waives and agrees not
to assert any defenses against an action for specific performance of such
covenants except for a defense that no default has occurred giving rise to the
Secured Obligations becoming due and payable prior to their stated maturities.
Nothing in this Section shall in any way alter the rights of the Collateral
Agent hereunder.

                  (c) The Collateral Agent may sell the Article 9 Collateral
without giving any warranties as to the Article 9 Collateral. The Collateral
Agent may specifically disclaim or modify any warranties of title or the like.
This procedure will not be considered to adversely effect the commercial
reasonableness of any sale of the Article 9 Collateral.

                  (d) The Collateral Agent shall have no obligation to marshal
any of the Article 9 Collateral.

      Section 7.2 Application of Proceeds. Except as expressly provided
elsewhere in this Agreement, all proceeds received by the Collateral Agent in
respect of any sale, any collection from, or other realization upon all or any
part of the Article 9 Collateral shall be applied in accordance with the terms
of the Collateral Trust Agreement.

      Section 7.3 Sales on Credit. If the Collateral Agent sells any of the
Article 9 Collateral upon credit, the Grantors will be credited only with
payments actually made by the purchaser and received by the Collateral Agent and
applied to indebtedness of the purchaser. In the event the purchaser fails to
pay for the Article 9 Collateral, the Collateral Agent may resell the Article 9
Collateral and the Grantors will be credited with proceeds of the sale.

      Section 7.4 Investment Property.

                  (a) Each Grantor recognizes that, by reason of certain
prohibitions contained in the Securities Act of 1933 and applicable state
securities laws, the Collateral Agent may be compelled, with respect to any sale
of all or any part of the Investment Property conducted without prior
registration or qualification of such Investment Property under the Securities
Act and/or such state securities laws, to limit purchasers to those who will
agree, among other things, to acquire the Investment Property for their own
account, for investment and not with a view to the distribution or resale
thereof. Each Grantor acknowledges that any such private sale may be at prices
and on terms less favorable than those obtainable through a public sale without
such restrictions (including a public offering made pursuant to a registration
statement under the Securities Act) and, notwithstanding such circumstances,
each Grantor agrees that any such private sale shall be deemed to have been made
in a commercially reasonable manner and that the Collateral Agent shall have no
obligation to engage in public sales and no obligation to delay the sale of any
Investment Property for the period of time necessary to permit the issuer
thereof to register it for a form of public sale requiring registration

<PAGE>

under the Securities Act or under applicable state securities laws, even if such
issuer would, or should, agree to so register it.

                  (b) Upon the occurrence and during the continuation of an
Event of Default, the Collateral Agent shall have the right to apply the balance
from any Deposit Account or instruct the bank at which any Deposit Account is
maintained to pay the balance of any Deposit Account to or for the benefit of
the Collateral Agent.

      Section 7.5 Cash Proceeds. Cash Proceeds shall be held by each Grantor in
trust for the Collateral Agent, segregated from other funds of such Grantor.
Such Cash Proceeds shall, within 10 Business Days of receipt by such Grantor, be
turned over to the Collateral Agent in the exact form received by such Grantor
(duly indorsed by such Grantor to the Collateral Agent, if required) and held by
the Collateral Agent in the Revenue Account. Any Cash Proceeds of a Grantor
received by the Collateral Agent: (i) if no Event of Default shall have occurred
and be continuing under any Secured Debt Document, shall be held by the
Collateral Agent for the benefit of the Secured Parties, as collateral security
for the Secured Obligations (whether matured or unmatured), and (ii) if an Event
of Default shall have occurred and be continuing, (A) be held by the Collateral
Agent for the benefit of the Secured Parties, as collateral security for the
Secured Obligations (whether matured or unmatured), and/or (B) be applied by the
Collateral Agent against any Secured Obligations due and owing.

                                  ARTICLE VIII.
                                COLLATERAL AGENT

            The Collateral Agent has been appointed to act as Collateral Agent
hereunder by each Secured Party pursuant to the Collateral Trust Agreement. The
Collateral Agent shall have the right hereunder, to make demands, to give
notices, to exercise or refrain from exercising any rights, and to take or
refrain from taking any action (including, without limitation, the release or
substitution of Article 9 Collateral), solely in accordance with this Agreement
and the Collateral Trust Agreement. In furtherance of the foregoing provisions
of this Section, each Secured Party, by its acceptance of the benefits hereof
and pursuant to the terms of the Collateral Trust Agreement, agrees that it
shall have no right individually to realize upon any of the Collateral
hereunder, it being understood and agreed by such Secured Party that all rights
and remedies hereunder may be exercised solely by the Collateral Agent following
receipt of lawful directions given to it pursuant to the terms of the Collateral
Trust Agreement for the benefit of each Secured Party in accordance with the
terms of this Section and the Collateral Trust Agreement.

                                   ARTICLE IX.
         CONTINUING SECURITY INTEREST; TRANSFER OF SECURED OBLIGATIONS

            This Agreement shall create a continuing security interest in the
Article 9 Collateral and shall remain in full force and effect with respect to
all Collateral until the Secured Obligations Termination Date and shall be
binding upon each Grantor, its successors and assigns, and inure, together with
the rights and remedies of the Collateral Agent hereunder, to the benefit of the
Collateral Agent and its successors, transferees and assigns. Without limiting
the generality of the foregoing, but subject to the terms of the Secured Debt
Documents, each Secured Party may assign or otherwise transfer any Secured
Obligations held by it to any other

<PAGE>

Person, and such other Person shall thereupon become vested with all the
benefits in respect thereof granted to each Secured Party herein or otherwise.
Upon the Secured Obligations Termination Date, the security interest granted
therein under this Agreement shall terminate hereunder and of record and all
rights to such Collateral shall revert to the applicable Grantor. Upon any such
termination the Collateral Agent shall, at the Grantors' expense, execute and
deliver to such Grantor such documents as such Grantor shall reasonably request
to evidence such termination.

                                   ARTICLE X.
                 STANDARD OF CARE; COLLATERAL AGENT MAY PERFORM

            The powers conferred on the Collateral Agent hereunder are solely to
protect its interest in the Article 9 Collateral and the interests of the
Secured Parties and shall not impose any duty upon it to exercise any such
powers. Except for the exercise of reasonable care in the custody of any Article
9 Collateral in its possession and the accounting for moneys actually received
by it hereunder, the Collateral Agent shall have no duty as to any Article 9
Collateral or as to the taking of any necessary steps or actions of any type to
preserve rights against prior parties or any other rights pertaining to any
Article 9 Collateral. The Collateral Agent shall be deemed to have exercised
reasonable care in the custody and preservation of Article 9 Collateral in its
possession if such Article 9 Collateral is accorded treatment substantially
equal to that which the Collateral Agent accords its own property. Neither the
Collateral Agent, its Affiliates nor any of their directors, officers, employees
or agents shall be liable for failure to demand, collect or realize upon all or
any part of the Article 9 Collateral or for any delay in doing so or shall be
under any obligation to sell or otherwise dispose of any Article 9 Collateral
upon the request of any Grantor or otherwise. If any Grantor fails to perform
any material agreement contained herein, the Collateral Agent may itself
perform, or cause performance of, such agreement, and the reasonable expenses of
the Collateral Agent incurred in connection therewith shall be payable by such
Grantor under Article XI.

                                   ARTICLE XI.
                             INDEMNITY AND EXPENSES

                  (a) Each Grantor agrees, jointly and severally:

                        (i) to defend (subject to the Indemnitees' selection of
counsel), indemnify, pay and hold harmless each Indemnitee, from and against any
and all actions, claims, losses and liabilities in any way relating to, growing
out of or resulting from this Agreement and the transactions with respect to the
Grantors and the Article 9 Collateral contemplated hereby (including without
limitation enforcement of this Agreement), except to the extent such actions,
claims, losses or liabilities result from such Indemnitee's bad faith, gross
negligence or willful misconduct as determined by a court of competent
jurisdiction; and

                        (ii) to reimburse the Collateral Agent promptly
following written demand the amount of any and all reasonable costs and
reasonable expenses, including the reasonable fees and expenses of its counsel
and of any experts and agents, with respect to the Grantors and the Article 9
Collateral.

<PAGE>

                  (b) Notwithstanding anything herein or implied by law to the
contrary, the obligations of each Grantor in this Article XI shall survive the
termination of this Agreement, any resignation or removal of the Collateral
Agent and the discharge of such Grantor's other obligations under this Agreement
and the other Secured Debt Documents.

                                  ARTICLE XII.
                                 MISCELLANEOUS

      Section 12.1 Notices. Unless otherwise specifically provided herein, any
notice or other communication herein required or permitted to be given to a
Grantor or the Collateral Agent shall be sent to such Person's address set forth
in Section 8.5 of the Collateral Trust Agreement and in the manner provided
therein.

      Section 12.2 Amendments and Waivers.

                  (a) Collateral Agent's Consent. Subject to Section 12.2(b), no
amendment, modification, termination or waiver of any provision of this
Agreement, or consent to any departure by any Grantor therefrom, shall in any
event be effective without the written concurrence of the Collateral Agent.

                  (b) No Waiver; Remedies Cumulative. No failure or delay on the
part of the Collateral Agent in the exercise of any power, right or privilege
hereunder or under any other Secured Debt Document shall impair such power,
right or privilege or be construed to be a waiver of any default or acquiescence
therein, nor shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other power,
right or privilege. All rights, powers and remedies existing under this
Agreement and the other Secured Debt Documents are cumulative, and not exclusive
of, any rights or remedies otherwise available. Any forbearance or failure to
exercise, and any delay in exercising, any right, power or remedy hereunder
shall not impair any such right, power or remedy or be construed to be a waiver
thereof, nor shall it preclude the further exercise of any such right, power or
remedy.

      Section 12.3 Successors and Assigns. This Agreement shall be binding upon
the parties hereto and their respective successors and assigns including all
persons who become bound as debtor to this Agreement. No Grantor shall, without
the prior written consent of the Collateral Agent, assign any right, duty or
obligation hereunder.

      Section 12.4 Independence of Covenants. All covenants hereunder shall be
given independent effect so that if a particular action or condition is not
permitted by any of such covenants, the fact that it would be permitted by an
exception to, or would otherwise be within the limitations of, another covenant
shall not avoid the occurrence of an Event of Default if such action is taken or
condition exists.

      Section 12.5 Severability. In case any provision in or obligation
hereunder shall be invalid, illegal or unenforceable in any jurisdiction, the
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

<PAGE>

      Section 12.6 Headings. Section headings herein are included herein for

other purpose or be given any substantive effect.

ACTION BASED UPON OR ARISING HEREUNDER OR UNDER ANY OF THE OTHER TRANSACTION
DOCUMENTS. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY
AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT
MATTER OF THIS TRANSACTION, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF
DUTY CLAIMS AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. EACH PARTY HERETO
ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS
RELATIONSHIP, THAT EACH HAS ALREADY RELIED ON THIS WAIVER IN ENTERING INTO THIS
AGREEMENT, AND THAT EACH WILL CONTINUE TO RELY ON THIS WAIVER IN ITS RELATED
FUTURE DEALINGS. EACH PARTY HERETO FURTHER WARRANTS AND REPRESENTS THAT IT HAS
REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL AND THAT IT KNOWINGLY AND
VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL

REFERRING TO THIS SECTION 12.9 AND EXECUTED BY EACH OF THE PARTIES HERETO), AND
THIS

<PAGE>

WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS HERETO. IN THE EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED AS
A WRITTEN CONSENT TO A TRIAL BY THE COURT.

      Section 12.10 Counterparts. This Agreement may be executed in any number
of counterparts, each of which when so executed and delivered shall be deemed an

no unwritten oral agreements between the parties.

Collateral Agent or any other Secured Party hereunder or pursuant hereto is

such Secured Party upon an Insolvency Proceeding of any Grantor, or upon the
appointment of any intervenor or conservator of, or trustee or similar official

benefits, privileges, immunities and indemnities given to the Collateral Agent

                                    RECITALS

            WHEREAS, the parties hereto acknowledge that the Grantor has granted

restated, supplemented and otherwise modified from time to time, the "Security

                                    AGREEMENT

            NOW, THEREFORE, in consideration of the premises herein and for
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto hereby agree for the benefit of the
Secured Parties as follows:

-----------------
(2)   If required by the Financial Institution, such capitalized terms which are
      not defined in this form shall be defined based on the definitions set
      forth in the Collateral Trust Agreement.

                                    ANNEX A-1

<PAGE>

            SECTION 1. ESTABLISHMENT AND MAINTENANCE OF PLEDGED ACCOUNTS.

                  (a)   The Financial Institution hereby represents and warrants
that it has established and currently maintains the accounts listed on Schedule
1 hereto and that the Grantor is its sole customer or entitlement holder with
respect to each such account. Each such account and any successor account and
all other accounts that the Grantor now or hereafter maintains with the
Financial Institution, being referred to herein individually as a "Pledged
Account" and collectively as the "pledged accounts." The Financial Institution
covenants and agrees that it shall not change the name or account number of any
Pledged Account without the prior written consent of the Collateral Agent;

                  (b)   Each of the parties hereto acknowledges and agrees that
the accounts listed on Part A of Schedule 1 hereto are intended to be deposit
accounts (as defined in Section 9-102(a)(29) of the UCC) and the accounts listed
on Part B of Schedule 1 hereto are intended to be securities accounts (as
defined in Section 8-501 of the UCC). Notwithstanding such intention, as used
herein "Deposit Account" shall mean any Pledged Account (or any part thereof)
that is determined to be a "deposit account" (within the meaning of Section
9-102(a)(29) of the UCC) and "Securities Account" shall mean any Pledged Account
(or any part thereof) that is determined to be a "securities account" (within
the meaning of Section 8-501 of the UCC).

                  (c)   The Financial Institution covenants and agrees that: (i)
all securities or other property underlying any financial assets credited to any
Securities Account shall be registered in the name of the Financial Institution,
indorsed to the Financial Institution or indorsed in blank or credited to
another securities account maintained in the name of the Financial Institution;
(ii) in no case will any financial asset credited to any Securities Account be
registered in the name of the Grantor, payable to the order of the Grantor or
specially indorsed to the Grantor except to the extent the foregoing have been
specially indorsed to the Financial Institution or indorsed in blank; and (iii)
all such property delivered to the Financial Institution pursuant to the
Security Agreement will be promptly credited to one of the Pledged Accounts.

            SECTION 2. "FINANCIAL ASSETS" ELECTION. The Financial Institution
hereby agrees that each item of property (including, without limitation, all
Cash Equivalents and any investment property, financial asset, security,
instrument or cash) credited to any Pledged Account that is a Securities Account
shall be treated as a "financial asset" within the meaning of Section
8-102(a)(9) of the UCC.

            SECTION 3. COLLATERAL AGENT'S CONTROL OF THE PLEDGED ACCOUNTS. If at
any time after the Collateral Agent has delivered to the Financial Institution a
Notice of Default in substantially the form set forth in Exhibit A hereto or the
Financial Institution shall receive from the Collateral Agent an entitlement
order (i.e., an order directing transfer or redemption of any financial asset
relating to a Pledged Account) or any instruction (within the meaning of Section
9-104 of the UCC, i.e., an instruction directing the disposition of funds in a
Pledged Account) originated by the Collateral Agent, the Financial Institution
shall comply with such entitlement order or instruction without further consent
by the Grantor or any other person. The Collateral Agent agrees not to deliver a
Notice of Default unless an Event of Default (as defined below) has occurred;
however, it is understood and agreed that the Financial Institution shall rely
exclusively on a Notice of Default as to the existence of an Event of Default
and shall be under

                                    ANNEX A-2

<PAGE>

no obligation to make any independent investigation as to the existence of an
Event of Default. If the Grantor is otherwise entitled to give any entitlement
orders or instructions with respect to the Pledged Accounts in accordance with
Section 4 hereof and such entitlement orders or instructions conflict with
instructions of the Collateral Agent, the Financial Institution shall comply
with the entitlement orders and instructions issued by the Collateral Agent. For
purposes of this Agreement, "Event of Default" means an "Event of Default" under
and as defined in any of the Indentures, the Term Loan Agreements, the Revolving
Loan Agreement or any other Secured Debt Document.

            In the event that any of the Pledged Accounts is not considered a
"securities account" or "deposit account" under applicable law or a security
interest cannot be granted and perfected in such Pledged Accounts under the UCC,
then such Pledged Accounts and all property deposited therein shall be deemed
under the exclusive dominion and control of the Collateral Agent, and the
Financial Institution as its agent, for the purpose of the creation and
perfection of security interests in favor of the Collateral Agent for the
benefit of the Secured Parties.

            SECTION 4. GRANTOR'S ACCESS TO THE PLEDGED ACCOUNTS. If at any time
the Collateral Agent has delivered to the Financial Institution a Notice of
Default in substantially the form set forth in Exhibit A hereto, then the
Financial Institution agrees that thereafter until the Collateral Agent has
informed the Financial Institution in writing that the Event of Default no
longer exists, it will take all directions with respect to the Pledged Accounts
solely from the Collateral Agent and shall not comply with instructions or
entitlement orders of the Grantor or any other person. So long as no Notice of
Default has been delivered to the Financial Institution by the Collateral Agent,
the Grantor shall be entitled to give, and the Collateral Agent may act upon,
any entitlement order or instruction with respect to the Pledged Accounts as it
deems appropriate.

            SECTION 5. SUBORDINATION OF LIEN; WAIVER OF SET-OFF. In the event
that the Financial Institution has or subsequently obtains by agreement, by
operation of law or otherwise a security interest in any Pledged Account or any
financial assets, cash or other property credited thereto, the Financial
Institution hereby agrees that such security interest shall be subordinate to
the security interest of the Collateral Agent The financial assets, money and
other items credited to any Pledged Account will not be subject to deduction,
set-off, banker's lien, or any other right in favor of any person other than the
Collateral Agent (except that the Financial Institution may set off (i) all
amounts due to the Financial Institution in respect of customary fees and
expenses for the routine maintenance and operation of the respective Pledged
Account and (ii) the face amount of any checks which have been credited to such
Pledged Account but are subsequently returned unpaid because of uncollected or
insufficient funds).

            SECTION 6. CHOICE OF LAW. This Agreement shall be governed by the
laws of the State of New York. Regardless of any provision in any other
agreement, for purposes of the UCC, with respect to each Pledged Account New
York shall be deemed to be the bank's jurisdiction (within the meaning of
Section 9-304 of the UCC) and the securities intermediary's jurisdiction (within
the meaning of Section 8-110 of the UCC). The Pledged Accounts shall be governed
by the laws of the State of New York.

                                    ANNEX A-3

<PAGE>

            SECTION 7. CONFLICT WITH OTHER AGREEMENTS. The Financial Institution
hereby represents, warrants, covenants and agrees that:

                  (a)   there are no other agreements entered into between the
Financial Institution and the Grantor with respect to any Pledged Account (other
than those referred to herein);

                  (b)   it has not entered into, and until the termination of
this Agreement will not enter into, any agreement with any other person relating
the Pledged Accounts and/or any financial assets credited thereto pursuant to
which it agrees or has agreed to comply with entitlement orders (as defined in
Section 8-102(a)(8) of the UCC) or instructions (within the meaning of Section
9-104 of the UCC) of such other person;

                  (c)   it has not entered into, and until the termination of
this Agreement will not enter into, any agreement with the Grantor or the
Collateral Agent purporting to limit or condition the obligation of the
Financial Institution to comply with entitlement orders or instructions, except
as may be otherwise provided herein; and

                  (d)   in the event of any conflict between this Agreement (or
any portion thereof) and any other agreement now existing or hereafter entered
into, the terms of this Agreement shall prevail.

            Notwithstanding the foregoing, it is hereby agreed that the
Collateral Agent and the Financial Institution shall be afforded all of the
rights, powers, protections and immunities set forth in the Collateral Trust
Agreement, the Security Agreement and any other Secured Debt Document to which
they are a party as if the same were specifically set forth herein.

            SECTION 8. ADVERSE CLAIMS. The Financial Institution represents and
warrants that, except for the claims and interest of the Collateral Agent, the
Financial Institution and of the Grantor in the Pledged Accounts, it does not
know of any security interest in, lien on or claim to, or other interest in, any
Pledged Account or in any "financial asset" (as defined in Section 8-102(a) of
the UCC) credited thereto. If any person asserts any lien, encumbrance or
adverse claim (including any writ, garnishment, judgment, warrant of attachment,
execution or similar process) against the Pledged Accounts or in any financial
asset carried therein, the Financial Institution will promptly notify the
Collateral Agent and the Grantor thereof.

            SECTION 9. ADDITIONAL PROVISIONS REGARDING MAINTENANCE OF THE
PLEDGED ACCOUNTS. The Financial Institution covenants and agrees:

                  (a)   Statements and Confirmations. The Financial Institution
will promptly send copies of all statements, confirmations and other
correspondence concerning (i) any Securities Account and/or any financial assets
credited thereto and (ii) any Deposit Account, simultaneously to each of the
Grantor and the Collateral Agent at the address for each set forth in Section 13
of this Agreement.

                  (b)   Tax Reporting. All items of income, gain, expense and
loss recognized in any Securities Account and all interest, if any, relating to
any Deposit Account, shall be reported to the Internal Revenue Service and all
state and local taxing authorities under

                                    ANNEX A-4

                  (c)   Voting Rights. At any time during which the Grantor is
entitled to give entitlement orders pursuant to Section 4 hereof, the Grantor
shall direct the Financial Institution with respect to the voting of any
financial assets credited to the Pledged Accounts. At all other times, the
Collateral Agent shall control the right to vote with respect to such financial
assets.

                  (d)   Cash Equivalents. At any time during which the Grantor
is entitled to give entitlement orders pursuant to Section 4 hereof, the Grantor
shall direct the Financial Institution with respect to the selection of
investments to be made for any Securities Account; provided, however, that the
Financial Institution shall not honor any instruction to purchase any
investments other than Cash Equivalents. At all other times, the Collateral
Agent shall control the selection of investments to be made for any Securities
Account.
