                  SECTION 2.   THE COLLATERAL AGENT.

                  2.1      General Authority of the Collateral Agent over the
Collateral. (a) By acceptance of the benefits of this Agreement and the Security
Documents, each Secured Party shall be deemed irrevocably (i) to consent to the
appointment of the Collateral Agent as its agent hereunder and under the
Security Documents, (ii) to confirm that the Collateral Agent shall have the
authority to act as the exclusive agent of such Secured Party for executing and
delivering any amendments to the Security Documents and enforcement of any

                                       8

<PAGE>

Grantor or the exercise of remedies hereunder or thereunder, in accordance with
and to the extent consistent with this Agreement and the Security Documents,
(iii) to agree, except as provided in this Agreement and the Security Documents,
that such Secured Party shall not take any action (other than through the
Collateral Agent) to enforce any provisions of this Agreement or any Security
Document against any Grantor or to exercise any remedy hereunder or thereunder
and (iv) to agree to be bound by the terms of this Agreement and the Security
Documents. Each Representative of the Other Secured Parties, for itself and on
behalf of such Other Secured Parties, hereby irrevocably constitutes and
appoints the Collateral Agent and any officer or agent of the Collateral Agent,
with full power of substitution, as its true and lawful attorney-in-fact with
full irrevocable power and authority in the place and stead of such
Representative and Other Secured Parties, as applicable, or in the Collateral
Agent's own name, from time to time in the Collateral Agent's discretion, for
the purpose of carrying out the terms of this Section 2.1, to take any and all
appropriate action and to execute any and all documents and instruments which
may be necessary or desirable to accomplish the purposes of this Section 2.1,
including any termination statements, endorsements or other instruments of
transfer or release, in accordance with this Agreement and the Security
Documents.

                  (b) The Collateral Agent hereby agrees that it holds and will
hold all of its right, title and interest in, to and under the Security
Documents and the Collateral granted to the Collateral Agent thereunder whether
now existing or hereafter arising (all such right, title and interest being
hereinafter referred to as the "Collateral Estate") under and subject to the
conditions set forth in this Agreement and the Security Documents; and the
Collateral Agent further agrees that it will hold such Collateral Estate in
trust for the ratable benefit of the relevant Secured Parties, for the
enforcement of the payment of all Secured Obligations secured by the relevant
Collateral (subject to the limitations and priorities set forth herein and in
the Security Documents) and as security for the performance of and compliance
with the covenants and conditions of this Agreement and each of the Security
Documents.

                  2.2      Information as to Secured Parties and
Representatives. The Companies shall deliver to the Collateral Agent from time
to time after the date hereof upon request of the Collateral Agent a list
setting forth as of a date not more than 30 days prior to the date of such
delivery, (a) the aggregate unpaid principal amount of the Senior Lender Claims
outstanding, (b) the aggregate unpaid principal amount of the Noteholder Claims
outstanding, and (c) to the extent known to the Company, the respective names
and addresses of each Secured Party. In addition, the Companies will promptly
notify the Collateral Agent of each change in the identity of any
Representative. Promptly following the date hereof, the Trustee shall deliver to
the Collateral Agent the names of the officers of the Trustee authorized to give
directions hereunder on behalf of the Trustee. Each Representative of any Other
Secured Parties agrees to notify the Collateral Agent of any change of its
officers authorized to give directions hereunder on behalf of such
Representative prior to the date of any such change. If the Collateral Agent
does not receive the names of the officers of the Representative of any Other
Secured Parties authorized to give directions hereunder on behalf of such
Representative, the Collateral Agent may rely on any Person purporting to be
authorized to give directions hereunder on behalf of such Representative. If the
Collateral Agent is not informed of changes of the officers of the applicable
Representative of the Other Secured Parties authorized to give directions
hereunder on behalf of such Representative, the Collateral Agent may rely on the
information previously provided to the Collateral Agent.

                  2.3      The Collateral Agent. Each of the Secured Parties, by
its acceptance of the benefits hereof, hereby irrevocably appoints the
Collateral Agent as its agent and authorizes the Collateral Agent to take such
actions on its behalf and to exercise such powers as are delegated to the
Collateral Agent by the terms of this Agreement and the Security Documents,
together with such actions and powers as are reasonably incidental thereto.

<PAGE>

                  The bank serving as the Collateral Agent hereunder shall have
the same rights and powers in its capacity as a Senior Lender as any other
Senior Lender and may exercise the same as though it were not the Collateral
Agent, and such bank and its Affiliates may accept deposits from, lend money to
and generally engage in any kind of business with the Companies or any Grantor
or other Affiliate thereof as if it were not the Collateral Agent hereunder.

                  The Collateral Agent shall not have any duties or obligations
except those expressly set forth in this Agreement and the Security Documents.
The Collateral Agent shall make available for inspection by any Secured Party,
upon request of the Representative of such Secured Party, each certificate or
other paper furnished to the Collateral Agent by any Loan Party under or in
respect of this Agreement, any Security Document or any portion of the
Collateral Estate. The Companies hereby consent to the disclosure of such
requested documents by the Collateral Agent to the Secured Parties. Without
limiting the generality of the foregoing, (a) the Collateral Agent shall not be
subject to any fiduciary or other implied duties, regardless of whether a
default under the Credit Agreement or the Indenture has occurred and is
continuing, (b) the Collateral Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated by the Security Documents that the
Collateral Agent is required to exercise in writing by the Instructing Group
pursuant to this Agreement, and (c) except as expressly set forth in this
Agreement and the Security Documents, the Collateral Agent shall not have any
duty to disclose, and shall not be liable for the failure to disclose, any
information relating to either Company or any Grantor that is communicated to or
obtained by the bank serving as Collateral Agent or any of its Affiliates in any
capacity. The Collateral Agent shall not be liable for any action taken or not
taken by it with the consent or at the request of the Instructing Group pursuant
to this Agreement, or in the absence of its own gross negligence or wilful
misconduct. The Collateral Agent shall be deemed not to have knowledge of any
default or event of default under the Senior Loan Documents or the Noteholder
Documents, unless and until written notice thereof is given to the Collateral
Agent by either Company or any Representative, as applicable, and the Collateral
Agent shall not be responsible for or have any duty to ascertain or inquire into
(i) any statement, warranty or representation made in or in connection with any
Senior Loan Document or Noteholder Document, (ii) the contents of any
certificate, report or other document delivered thereunder or in connection
therewith, (iii) the performance or observance of any of the covenants,
agreements or other terms or conditions set forth in any Senior Loan Documents
or Noteholder Documents, (iv) the validity, enforceability, effectiveness or
genuineness of any Senior Loan Documents or Noteholder Documents or any other
agreement, instrument or document, or (v) the satisfaction of any condition set
forth in Article IV of the Existing Credit Agreement or elsewhere in any Senior
Loan Document or Noteholder Document, other than to confirm receipt of items
expressly required to be delivered to the Collateral Agent under the Senior Loan
Documents or the Noteholder Documents.

                  Whenever in the performance of its duties under this
Agreement, the Collateral Agent shall deem it necessary or desirable that a
matter be proved or established with respect to either Company, any Grantor or
any other Person in connection with the taking, suffering or omitting of any
action hereunder by the Collateral Agent, such matter may be conclusively deemed
to be proved or established by a certificate purporting to be executed by an
officer of such Person. The Collateral Agent shall be entitled to rely upon, and
shall not incur any liability with respect to any action taken, suffered or
omitted in reliance upon any such certificate, or any notice, request,
certificate, consent, statement, instrument, document or other writing believed
by it to be genuine and to have been signed or sent by the proper Person. The
Collateral Agent also may rely upon any statement made to it orally or by
telephone and believed by it to be made by the proper Person, and shall not
incur any liability for relying thereon. The Collateral Agent may consult with
legal counsel (who may be counsel for the Companies), independent accountants
and other experts selected by it, and shall not be liable for any action taken
or not taken by it in accordance with the advice of any such counsel,
accountants or experts.

                  The Collateral Agent may perform any and all its duties and
exercise its rights and powers by or through any one or more sub-agents
appointed by the Collateral Agent. The Collateral Agent and any such sub-agent
may perform any and all its duties and exercise its rights and powers through
their respective Related Parties. The exculpatory provisions of the preceding
paragraphs shall apply to any such sub-agent and to the Related Parties of the
Collateral Agent and any such sub-agent.

                  Subject to the appointment and acceptance of a successor
Collateral Agent as provided in this paragraph, the Collateral Agent may resign
at any time by notifying the Senior Lenders, the Trustee, the Representative of
any Other Secured Party and the Companies. Upon any such resignation and so long
as the Discharge of Senior Credit Agreement Claims has not occurred, the
Required Lenders shall have the right, in consultation with the Companies, to
appoint a successor, and if no successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after
the retiring Collateral Agent gives notice of its resignation, then the retiring
Collateral Agent may, on behalf of the Secured Parties, appoint a successor
Collateral Agent which shall be a bank with an office in New York, New York, or
an Affiliate of any such bank (unless otherwise agreed by the Companies and the
Required Lenders). Upon any such resignation of the Collateral Agent after the
Discharge of Senior Credit Agreement Claims has occurred, the Majority Secured
Parties shall have the right, in consultation with the Companies, to appoint a
successor, and if no successor shall have been so appointed and shall have
accepted such appointment within 15 days after the retiring Collateral Agent
gives notice of its resignation, then the Trustee shall be appointed the
successor Collateral Agent. If the Trustee shall not have accepted such
appointment, the Collateral Agent, the Companies or the Majority Secured Parties
may apply to any court of competent jurisdiction to appoint a successor
Collateral Agent to act until such time, if any, as a successor shall have been
appointed and shall have accepted such appointment as above provided.

                  Upon its appointment as Collateral Agent hereunder, a
successor Collateral Agent shall succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Collateral Agent, and the
retiring Collateral Agent shall be discharged from its duties and obligations
hereunder. Any successor Collateral Agent shall execute and deliver an
appropriate supplement or amendment to this Agreement and other necessary
amendments or supplements to the Security Documents to effect such appointment.
The fees payable by the Companies to a successor Collateral Agent shall be the
same as those payable to its predecessor unless otherwise agreed between the
Companies and such successor. After the Collateral Agent's resignation
hereunder, the provisions of this Section 2.3 and Section 2.4 shall continue in
effect for the benefit of such retiring Collateral Agent, its sub-agents and
their respective Related Parties in respect of any actions taken or omitted to
be taken by any of them while it was acting as Collateral Agent.

                  2.4      Collateral Agent's Fees; Indemnification. (a) Each
Grantor jointly and severally agrees to pay upon demand to the Collateral Agent
the amount of any and all reasonable expenses, including the reasonable fees,
disbursements and other charges of its counsel and of any experts or agents,
which the Collateral Agent may incur in connection with this Agreement.

                  (b) Without limitation of its indemnification obligations
under the Security Documents, the Senior Loan Documents or the Noteholder
Documents, each Grantor jointly and severally agrees to indemnify the Collateral
Agent and its Related Parties against, and hold each of them harmless from, (i)
any and all losses, claims, damages, liabilities and related expenses, including
reasonable fees, disbursements and other charges of counsel, incurred by or
asserted against any of them arising out of, in any way connected with, or as a
result of, the execution, delivery or performance of this Agreement or any
claim, litigation, investigation or proceeding relating hereto or to the
Collateral, whether or not such Person is a party thereto; provided that such
indemnity shall not, as to the Collateral Agent and its Related

                                       11

<PAGE>

Parties, be available to the 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 such Person and (ii) any and all present or
future claims or liability for any recording, stamp, documentary, excise,
transfer, sales, property or similar taxes, charges or levies incurred in
connection with this Agreement.

                  (c) Any such amounts payable as provided hereunder shall be
additional Secured Obligations secured by the Security Documents. The provisions
of this Section 2.4 shall remain operative and in full force and effect
regardless of the termination of this Agreement, any Security Document, the
Collateral Sharing Agreement, any Senior Loan Document or any Noteholder
Document, the consummation of the transactions contemplated hereby, the
repayment of any of the Secured Obligations, the invalidity or unenforceability
of any term or provision of this Agreement, any Security Document, any Senior
Loan Document or any Noteholder Document, or any investigation made by or on
behalf of the Collateral Agent or any other Secured Party. All amounts due under
this Section 2.4 shall be payable on written demand therefor and shall bear
interest at the rate specified in Section 2.13(c) of the Credit Agreement.

                  (d) Notwithstanding anything to the contrary in this
Agreement, as security for the payment of the Collateral Agent Fees, (i) the
Collateral Agent is hereby granted a lien upon all Collateral and (ii) the
Collateral Agent shall have the right to use and apply any of the funds held by
the Collateral Agent in the Collateral Account to cover unpaid Collateral Agent
Fees.

                  SECTION 3.   ENFORCEMENT; DETERMINATIONS RELATING TO
                               COLLATERAL.

                  3.1      Exercise of Remedies. So long as the Discharge of
Senior Lender Claims has not occurred, whether or not any Insolvency or
Liquidation Proceeding has been commenced by or against either Company or any
other Grantor, (i) the Other Secured Parties will not exercise or seek to
exercise any rights or remedies with respect to any Collateral, institute any
action or proceeding with respect to such rights or remedies (including any
action of foreclosure), contest, protest or object to any foreclosure proceeding
or action brought by the Collateral Agent or, if the Discharge of Senior Credit
Agreement Claims has not occurred, any Senior Credit Agreement Lender, the
exercise of any right under any lockbox agreement, landlord waiver or bailee's
letter or similar agreement or arrangement to which any Other Secured Party is a
party, or any other exercise by any such party, of any rights and remedies
relating to the Collateral under the Security Documents or otherwise, or object
to the forbearance by the Collateral Agent or, if the Discharge of Senior Credit
Agreement Claims has not occurred, the Senior Credit Agreement Lenders, from
bringing or pursuing any foreclosure proceeding or action or any other exercise
of any rights or remedies relating to the Collateral, (ii) the Collateral Agent
shall have the exclusive right to enforce rights, exercise remedies and make
determinations regarding the release, disposition, or restrictions with respect
to the Collateral in accordance with the terms of this Agreement and the
Security Documents, without any consultation with or the consent of any Other
Secured Party, and (iii) the Instructing Group shall have the exclusive right to
direct the Collateral Agent's exercise of any and all such rights, remedies and
determinations (it being understood that the foregoing shall not be construed to
prevent the Collateral Agent from taking actions permitted to be taken by it in
the absence of receipt of any direction from the Instructing Group); provided
that (A) in any Insolvency or Liquidation Proceeding commenced by or against
either Company or any Grantor, the Representative of any Other Secured Party may
file a claim or statement of interest with respect to any Noteholder Claims or
Senior Lender Claims with respect to which it is a Representative, and (B) the
Representative of any Other Secured Party may take any action (not adverse to
the rights of the Collateral Agent to exercise, or the Instructing Group to
direct the exercise of, remedies in respect of the Collateral) in order to
preserve or protect its Lien on the Collateral. In exercising rights and
remedies with respect to the Collateral, the

                                       12

<PAGE>

Collateral Agent may enforce (and the Instructing Group may direct the
enforcement of) the provisions of the Security Documents and exercise remedies
thereunder, all in such order and in such manner as they may determine in the
exercise of its (or their) sole discretion. Such exercise and enforcement shall
include the rights of an agent appointed by them to sell or otherwise dispose of
Collateral upon foreclosure, to incur expenses in connection with such sale or
disposition, and to exercise all the rights and remedies of a secured lender
under the Uniform Commercial Code of any applicable jurisdiction and of a
secured creditor under Bankruptcy Laws of any applicable jurisdiction.

                  3.2      Determinations relating to Collateral; Releases of
Collateral. (a) Subject to Sections 3.2(b), 5.2 and 5.3, so long as the
Discharge of Senior Lender Claims has not occurred, in the event (i) the
Collateral Agent shall receive any written request from any Loan Party under any
Security Document for consent or approval with respect to any matter or thing
relating to any Security Document, any Collateral or any Loan Party's
obligations with respect thereto or (ii) there shall be due to or from the
Collateral Agent under the provisions of any Security Document any material
performance or the delivery of any material instrument or (iii) the Collateral
Agent shall become aware of any nonperformance by any Loan Party of any covenant
or any breach of any representation or warranty set forth in any Security
Document, then, in each such event, the Collateral Agent shall advise the
Administrative Agent and, after the Discharge of Senior Credit Agreement Claims
has occurred, the Representatives of the Other Secured Parties, of the matter or
thing as to which consent has been requested or the performance or instrument
required to be delivered or the nonperformance or breach of which the Collateral
Agent has become aware. So long as the Discharge of the Senior Lender Claims has
not occurred, the Instructing Group shall have the exclusive authority to direct
the Collateral Agent's response to any of the events or circumstances
contemplated in clauses (i), (ii) and (iii) above.

                  (b) If in connection with:

                           (i)      the exercise of the Collateral Agent's
         remedies in respect of the Collateral provided for in Section 3.1,
         including any sale, lease, exchange, transfer or other disposition of
         any such Collateral;

                           (ii)     any sale, lease, exchange, transfer or other
         disposition of any Collateral; or

                           (iii)    any other request by any Loan Party that any
         Collateral be released from the Liens thereon granted under any
         Security Document;

the Collateral Agent releases any Collateral from the Liens thereon granted
under any of the Security Documents, then such Liens shall be released with
respect to such Collateral and such release shall be binding upon all Secured
Parties, and the Collateral Agent shall not have any liability to any Secured
Party on account of such reliance; provided that, in the case of any release
made in connection with clause (ii) or (iii) above, such release shall be
permitted or not prohibited by the terms of the Senior Credit Agreement,
including by virtue of the consent of the Required Lenders, and the Indenture
(including Sections 10.03 and 11.03 of the Indenture) (and the Collateral Agent
shall be fully protected if it shall receive a certificate signed by an officer
of either Company to such effect). It is understood that the foregoing proviso
shall not apply to releases of Collateral expressly contemplated and permitted
by any Security Document to be effective without the necessity of any consent,
and the Collateral Agent may confirm any such release at the request of any
Grantor without liability to any Secured Party.

                  3.3      Cooperation. Subject to the proviso to the first
sentence of Section 3.1 above each Representative of any Other Secured Parties
agrees (on behalf of itself and such Other Secured Parties)

                                       13

<PAGE>

that, unless and until the Discharge of Senior Credit Agreement Claims has
occurred, it will not commence, or join with any Person (other than the Senior
Credit Agreement Lenders and the Collateral Agent upon the request thereof) in
commencing, any enforcement, collection, execution, levy or foreclosure action
or proceeding with respect to any Lien under any of the Security Documents or
otherwise.

                  3.4      Exercise of Powers. All of the powers, remedies and
rights of the Collateral Agent as set forth in this Agreement may be exercised
by the Collateral Agent in respect of any Security Document as though set forth
in full therein and all of the powers, remedies and rights of the Collateral
Agent as set forth in any Security Document may be exercised from time to time
as herein and therein provided.

                  SECTION 4.   COLLATERAL ACCOUNT; DISTRIBUTIONS.

                  4.1      The Collateral Account. At such time as the
Collateral Agent deems appropriate, the Collateral Agent shall establish and, at
all times thereafter until this Agreement shall have terminated, there shall be
maintained with the Collateral Agent an account which shall be entitled the "ON
Semiconductor Collateral Account" (the "Collateral Account"). All moneys which
are received by the Collateral Agent or any agent or nominee of the Collateral
Agent in respect of the Collateral upon the exercise of the remedies in
accordance with the terms of this Agreement or any Security Document shall be
deposited in the Collateral Account and held by the Collateral Agent as part of
the Collateral Estate and applied and disbursed in accordance with the terms of
this Agreement. The Collateral Agent shall maintain such sub-accounts and
records with respect to the Collateral Account as will permit the segregation
and allocation of proceeds of Collateral in accordance with Section 4.4.

                  4.2      Control of Collateral Account. All right, title and
interest in and to the Collateral Account, and funds on deposit in the
Collateral Account, shall constitute part of the Collateral Estate. The
Collateral Account shall be subject to the exclusive dominion and control of the
Collateral Agent.

                  4.3      Investment of Funds Deposited in Collateral Account.
The Collateral Agent may, at the request of the Companies, invest and reinvest
moneys on deposit in the Collateral Account at any time in Permitted
Investments; provided that the Collateral Agent, in its sole discretion, may (a)
restrict such investments and reinvestments to Permitted Investments that have a
shorter duration and higher credit quality than other Permitted Investments and
(b) decline to invest or reinvest any amount that it expects to distribute from
the Collateral Account within one Business Day. All such investments and the
interest and income received thereon and the net proceeds realized on the sale
or redemption thereof shall be held in the Collateral Account as part of the
Collateral Estate. The Collateral Agent shall not be responsible for any
diminution in funds resulting from such investments or any liquidation prior to
maturity.

                  4.4      Application of Moneys. (a) The Collateral Agent shall
have the right at any time to apply moneys held by it in the Collateral Account
to the payment of due and unpaid Collateral Agent Fees.

                  (b) All remaining moneys held by the Collateral Agent in the
Collateral Account received by the Collateral Agent with respect to the
Collateral shall, to the extent available for distribution (it being understood
that the Collateral Agent may liquidate investments prior to maturity in order
to make a distribution pursuant to this Section 4.4), be distributed (subject to
the provisions of Sections 4.5 and 4.6) by the Collateral Agent on each
Distribution Date in the following order of priority:

                                       14

<PAGE>

                  First: to the Collateral Agent for any unpaid Collateral Agent
         Fees and then to any Secured Party which has theretofore advanced or
         paid any Collateral Agent Fees constituting administrative expenses
         allowable under Section 503(b) of Title 11 of the United States Code,
         an amount equal to the amount thereof so advanced or paid by such
         Secured Party and for which such Secured Party has not been reimbursed
         prior to such Distribution Date, and, if such moneys shall be
         insufficient to pay such amounts in full, then ratably (without
         priority of any one over any other) to such Secured Parties in
         proportion to the amounts of such Collateral Agent Fees advanced by the
         respective Secured Parties and remaining unpaid on such Distribution
         Date;

                  Second: to any Secured Party which has theretofore advanced or
         paid any Collateral Agent Fees other than such administrative expenses,
         an amount equal to the amount thereof so advanced or paid by such
         Secured Party and for which such Secured Party has not been reimbursed
         prior to such Distribution Date, and, if such moneys shall be
         insufficient to pay such amounts in full, then ratably (without
         priority of any one over any other) to such Secured Parties in
         proportion to the amounts of such Collateral Agent Fees advanced by the
         respective Secured Parties and remaining unpaid on such Distribution
         Date;

                  Third: to the Secured Parties that hold Secured Obligations,
         in an amount equal to all Secured Obligations then owing to them,
         whether or not then due and payable, and, if such moneys shall be
         insufficient to pay such amounts in full, then ratably (without
         priority of any one over any other) to such Secured Parties in
         proportion to the unpaid amounts thereof on such Distribution Date; and

                  Fourth: any surplus then remaining shall be paid (i) if any
         Obligations in respect of the Second-Lien Notes are then outstanding,
         to the trustee under the indenture governing the Second-Lien Notes in
         accordance with the terms of the Intercreditor Agreement and (ii) if
         there are no Obligations in respect of the Second-Lien Notes then
         outstanding, to the Grantors or their successors or assigns or to
         whomsoever may be lawfully entitled to receive the same or as a court
         of competent jurisdiction may direct.

                  (c) The term "unpaid" as used in Section 4.4(b) refers:

                  (i)  in the absence of an Insolvency or Liquidation Proceeding
         with respect to the relevant Loan Party or Loan Parties, to all amounts
         of the relevant Senior Lender Claims and Noteholder Claims (other than
         contingent indemnification and other contingent obligations as to which
         the applicable Grantor has not received a notice of claim) outstanding
         as of a Distribution Date (and for the purpose of this provision, the
         amount of the Senior Lender Claims then outstanding shall include the
         undrawn face amount of, and any unreimbursed drawings under, any letter
         of credit), and

                  (ii) during the pendency of an Insolvency or Liquidation
         Proceeding with respect to the relevant Grantor(s), to all amounts
         allowed by the bankruptcy court in respect of the relevant Senior
         Lender Claims and Noteholder Claims as a basis for distribution
         (including estimated amounts, if any, allowed in respect of contingent
         claims),

to the extent that prior distributions have not been made in respect thereof.

                  (d) Subject to Section 4.5, the Collateral Agent shall make
all payments and distributions under this Section 4.4 to the respective
Representatives of the Secured Parties, as applicable. Each such

                                       15

<PAGE>

Representative shall be responsible for insuring that amounts distributed to it
are distributed to the relevant Secured Parties in the order of priority set
forth herein.

                  4.5      Application of Moneys Distributable to
Representatives. If at any time any moneys collected or received by the
Collateral Agent pursuant to this Agreement are distributable pursuant to
Section 4.4 to any Secured Party, the Collateral Agent may distribute such
moneys to the Representative of such Secured Party (and shall not be responsible
for the distribution of such moneys by such Representative); provided that if
any Representative shall notify the Collateral Agent in writing that no
provision is made under the Applicable Secured Documents for the application by
such Representative of such moneys (whether because the relevant Noteholder
Claims or Senior Lender Claims have not become due and payable or otherwise) and
that the Applicable Secured Documents do not effectively provide for the receipt
and the holding by such Representative of such moneys pending the application
thereof, then the Collateral Agent, after receipt of such notification, may, at
the request of the Companies, invest such amounts in Permitted Investments, and
shall hold all such amounts so distributable and all such investments and the
net proceeds thereof solely as security for the relevant Noteholder Claims or
Senior Lender Claims and for no other purpose until such time as such
Representative shall request in writing the delivery thereof by the Collateral
Agent for application pursuant to the Applicable Secured Documents; provided
further that the Collateral Agent, in its sole discretion, may (a) restrict such
investments to Permitted Investments that have a shorter duration and higher
credit quality than other Permitted Investments and (b) decline to invest any
amount that it expects to distribute within one Business Day. Notwithstanding
the foregoing, if, at any time, all the relevant Noteholder Claims or Senior
Lender Claims in respect of which any moneys and investments (and proceeds
thereof) are held by the Collateral Agent pursuant to this Section 4.5 cease to
be outstanding for any reason, then such moneys and any moneys that constitute
proceeds of such investments will be applied by the Collateral Agent in
accordance with Section 4.4(b). The Collateral Agent shall not be responsible
for any diminution in funds resulting from investments made at the direction of
the Companies or from holding such moneys uninvested.

                  4.6      Collateral Agent's Calculations. In making the
determinations and allocations required by Section 4.4, the Collateral Agent may
conclusively rely upon, and shall have no liability to any of the Secured
Parties for actions taken in reliance upon, information supplied by any Secured
Party (or its Representative) as to the amounts of unpaid principal and interest
and other amounts outstanding with respect to any Senior Lender Claims or the
Noteholder Claims; provided that nothing in this sentence shall prevent any
Grantor from contesting any amounts claimed by any Secured Party in any
information so supplied. All distributions made by the Collateral Agent pursuant
to Section 4.4 shall be (subject to any decree of any court of competent
jurisdiction) final (absent manifest error), and the Collateral Agent shall have
no duty to inquire as to the application by any Representative of any amounts
distributed to it for distribution to any Secured Parties.

                  4.7      Payments Over. Any Collateral or proceeds thereof
received by any Secured Party (or its Representative) in connection with the
exercise of any right or remedy relating to the Collateral in contravention of
this Agreement shall be segregated and held in trust and forthwith paid over to
the Collateral Agent in the same form as received, with any necessary
endorsements or as a court of competent jurisdiction may otherwise direct. The
Collateral Agent is hereby authorized to make any such endorsements as agent for
any Secured Party (or its Representative). This authorization is coupled with an
interest and is irrevocable.

                  SECTION 5.   OTHER AGREEMENTS.

                  5.1      Insurance. Unless and until the Discharge of Senior
Credit Agreement Claims has occurred, the Collateral Agent and the Required
Lenders shall have the sole and exclusive right, subject to the rights of the
Grantors under the Senior Credit Agreement and the Security Documents, to adjust
settlement for any insurance policy covering the Collateral in the event of any
loss thereunder and to approve any award granted in any condemnation or similar
proceeding affecting the Collateral. Unless and until the Discharge of Senior
Credit Agreement Claims has occurred, all proceeds of any such policy and any
such award if in respect to the Collateral shall be paid to the Collateral Agent
for the benefit of the Secured Parties to the extent required under the Senior
Credit Agreement, the Security Documents and the Noteholder Documents and
thereafter to the owner of the subject property or as a court of competent
jurisdiction may otherwise direct. If any Other Secured Party (or its
Representative) shall, at any time, receive any proceeds of any such insurance
policy or any such award in contravention of this Agreement, it shall pay such
proceeds over to the Collateral Agent in accordance with the terms of Section
4.7.

                  5.2      When Discharge of Senior Credit Agreement Claims
Deemed to Not Have Occurred. If at any time after the Discharge of Senior Credit
Agreement Claims has occurred the Companies designate any Future First-Lien
Credit Facility to be the "Senior Credit Agreement" hereunder, then such
Discharge of Senior Credit Agreement Claims shall automatically be deemed not to
have occurred for all purposes of this Agreement (other than with respect to any
actions taken prior to the date of such designation as a result of the
occurrence of such prior Discharge of Senior Credit Agreement Claims), and such
Future First-Lien Credit Facility shall automatically be treated as the Senior
Credit Agreement for all purposes of this Agreement. Upon receipt of notice of
such designation (including the identity of the new Collateral Agent), the
Trustee shall promptly (i) enter into such documents and agreements (including
amendments or supplements to this Agreement) as either Company or such new
Collateral Agent shall request in order to provide to the new Collateral Agent
the rights of the Collateral Agent contemplated hereby and (ii) deliver to the
Collateral Agent the Pledged Collateral together with any necessary endorsements
(or otherwise allow such Collateral Agent to obtain control of such Pledged
Collateral).

                  5.3      Amendments to Security Documents. Unless and until
the Discharge of Senior Lender Claims has occurred, the Instructing Group shall
have the exclusive authority to direct the Collateral Agent to (or consent to
any action by the Collateral Agent to) amend any provision of, or grant any
waivers or consents in respect of, any Security Document, without any consent or
approval of, or prior notice to, any other Secured Party; provided that no such
amendment, waiver or consent shall, without the written consent of the Trustee,
materially adversely affect the rights of the holders of the Noteholder Claims.

                  5.4      Right of Set-Off. Nothing in this Agreement shall
prevent any Secured Party from exercising any right of set-off or counterclaim
that such Secured Party may otherwise have.

                  SECTION 6.   INSOLVENCY OR LIQUIDATION PROCEEDINGS.

                  6.1      Financing Issues. If either Company or any other
Grantor shall be subject to any Insolvency or Liquidation Proceeding, the
Collateral Agent may, with the consent or at the direction of the Instructing
Group, on an equal and ratable basis, permit the use of cash Collateral or
permit either Company or any other Grantor to grant Liens on the Collateral to
secure financing under Section 363 or Section 364 of Title 11 of the United
States Code or any similar Bankruptcy Law ("DIP Financing"), and, in such event,
Representatives of the Other Secured Parties (on behalf of themselves and such
Other Secured Parties), agree that they will raise no objection to such use of
cash Collateral or DIP Financing

                                       17

<PAGE>

and will not request adequate protection or any other relief in connection
therewith (except to the extent contemplated by Section 6.3).

                  6.2      Relief from the Automatic Stay. Until the Discharge
of Senior Lender Claims has occurred, the Representatives of the Other Secured
Parties (on behalf of themselves and such Other Secured Parties) agree that none
of them shall seek relief from the automatic stay or any other stay in any
Insolvency or Liquidation Proceeding in respect of the Collateral, without the
prior written consent of the Instructing Group; provided that if the Senior
Credit Agreement Lenders or the Collateral Agent seek relief from the automatic
stay or any other stay in any Insolvency or Liquidation Proceeding in respect of
the Collateral, the request for such relief shall be made on behalf of all
Secured Parties (subject to their cooperation in joining in such request to the
extent necessary for such request to be made on behalf of all Secured Parties)
or the Representatives of the Other Secured Parties (on behalf of themselves and
the Other Secured Parties) shall be afforded an opportunity to join in or make
such request. The Representative of the Senior Credit Agreement Lenders shall
provide written notice to the Trustee (and to any other Representative of any
Other Secured Parties that has requested, by written notice to the
Representative of the Senior Credit Agreement Lenders, that it be so notified)
of any such request by the Senior Credit Agreement Lenders for relief from the
automatic stay or any other stay in any Insolvency or Liquidation Proceeding in
respect of the Collateral.

                  6.3      Adequate Protection. If the Discharge of Senior
Credit Agreement Claims has not occurred, the Representatives of the Other
Secured Parties (on behalf of themselves and such Other Secured Parties) agree
that none of them shall contest (or support any other Person contesting) (a) any
request by or on behalf of the Senior Credit Agreement Lenders for adequate
protection or (b) any objection by or on behalf of Senior Credit Agreement
Lenders to any motion, relief, action or proceeding based on the Senior Credit
Agreement Lenders claiming a lack of adequate protection; provided that in the
case of any such request or objection referred to in clause (a) or (b) of this
sentence, either such request or objection shall be made on behalf of all
Secured Parties (subject to their cooperation in joining in such request or
objection to the extent necessary for such request or objection to be made on
behalf of all Secured Parties) or the Representatives of the Other Secured
Parties (on behalf of themselves and the Other Secured Parties) shall be
afforded an opportunity to join in or make such request or objection on an equal
and ratable basis. Notwithstanding the foregoing contained in this Section 6.3,
in any Insolvency or Liquidation Proceeding, if any Secured Party requests or is
granted adequate protection in the form of additional collateral in connection
with any DIP Financing or use of cash collateral under Section 363 or Section
364 of Title 11 of the United States Code or any similar Bankruptcy Law, then
the other Secured Parties may seek or request adequate protection in the form of
additional collateral on an equal and ratable basis. The Representative of the
Senior Credit Agreement Lenders shall provide written notice to the Trustee (and
to any other Representative of any Other Secured Parties that has requested, by
written notice to the Representative of the Senior Credit Agreement Lenders,
that it be so notified) of any such request by the Senior Credit Agreement
Lenders for adequate protection or any such objection by the Senior Credit
Agreement Lenders claiming a lack of adequate protection.

                  6.4      Preference Issues. If any Secured Party is required
in any Insolvency or Liquidation Proceeding or otherwise to turn over or
otherwise pay to the estate of either Company or any other Grantor any amount (a
"Recovery"), then the Secured Obligations shall be reinstated to the extent of
such Recovery. If this Agreement shall have been terminated prior to such
Recovery, this Agreement shall be reinstated in full force and effect, and such
prior termination shall not diminish, release, discharge, impair or otherwise
affect the obligations of the parties hereto from such date of reinstatement.

                  SECTION 7.   RELIANCE; WAIVERS; ETC.

                  7.1      Reliance. The consent by the Required Lenders to the
execution and delivery of amendments to the Security Documents to provide that
the Noteholder Claims are secured by the Liens or the Collateral granted
thereunder, and all loans and other extensions of credit made or deemed made on
and after the date hereof by the Senior Lenders to either Company or any
Grantor, shall be deemed to have been given and made in reliance upon this
Agreement. The Trustee, on behalf of itself and the Noteholders, acknowledges
that it and the Noteholders have, independently and without reliance on the
Collateral Agent or any Senior Lender, and based on documents and information
deemed by them appropriate, made their own credit analysis and decision to enter
into the Indenture, this Agreement and the transactions contemplated hereby and
thereby and they will continue to make their own credit decision in taking or
not taking any action under the Indenture or this Agreement.

                  7.2      No Warranties or Liability. The Trustee, on behalf of
itself and the Noteholders, acknowledges and agrees that each of the Collateral
Agent and the Senior Lenders has made no express or implied representation or
warranty, including with respect to the execution, validity, legality,
completeness, collectibility or enforceability of any of the Security Documents,
the ownership of any Collateral or the perfection or priority of any Liens
thereon. The Senior Lenders will be entitled to manage and supervise their
respective loans and extensions of credit under the Senior Loan Documents in
accordance with law and as they may otherwise, in their sole discretion, deem
appropriate, and the Senior Lenders may manage their loans and extensions of
credit without regard to any rights or interests that the Trustee or any of the
Noteholders have in the Collateral or otherwise, except as otherwise provided in
this Agreement and the Security Documents. Neither any Senior Lender nor any of
their Representatives shall have any duty to the Trustee or any of the
Noteholders to act or refrain from acting in a manner which allows, or results
in, the occurrence or continuance of an event of default or default under any
agreements with either Company or any Subsidiary thereof (including the
Noteholder Documents), regardless of any knowledge thereof which they may have
or be charged with.

                  7.3      No Waiver.

                  (a) No right of the Senior Lenders, the Collateral Agent or
any of them to enforce any provision of this Agreement, any Senior Loan Document
or any Security Document shall at any time in any way be prejudiced or impaired
by any act or failure to act on the part of either Company or any other Grantor
or by any act or failure to act by any Senior Lender or the Collateral Agent, or
by any noncompliance by any Person with the terms, provisions and covenants of
this Agreement, any Senior Loan Document, any Noteholder Document or any
Security Document, regardless of any knowledge thereof which the Collateral
Agent or the Senior Lenders, or any of them, may have or be otherwise charged
with.

                  (b) The Trustee, on behalf of itself and the Noteholders,
agrees that the Senior Lenders and the Collateral Agent shall have no liability
to the Trustee or any Noteholder, and the Trustee, on behalf of itself and the
Noteholders, hereby waives any claim against any Senior Lender or the Collateral
Agent, arising out of any and all actions which the Senior Lenders may take or
permit or omit to take with respect to: (i) the Senior Loan Documents or (ii)
the collection of the Senior Lender Claims. The Trustee, on behalf of itself and
the Noteholders, agrees that the Senior Lenders and the Collateral Agent have no
duty to them in respect of the maintenance or preservation of the Collateral or
otherwise.

<PAGE>

                  7.4      Obligations Unconditional. All rights, interests,
agreements and obligations of the Collateral Agent and the Secured Parties
hereunder shall remain in full force and effect irrespective of:

                  (a) any lack of validity or enforceability of any Senior Loan
Documents or any Noteholder Documents;

                  (b) any change in the time, manner or place of payment of, or
in any other terms of, all or any of the Senior Lender Claims or Noteholder
Claims, or any amendment or waiver or other modification, including any increase
in the amount thereof, whether by course of conduct or otherwise, of the terms
of the Senior Credit Agreement or any other Senior Loan Document or of the terms
of the Indenture or any other Noteholder Document;

                  (c) any exchange of any security interest in any Collateral or
any other collateral, or any amendment, waiver or other modification, whether in
writing or by course of conduct or otherwise, of all or any of the Senior Lender
Claims or Noteholder Claims or any guarantee thereof;

                  (d) the commencement of any Insolvency or Liquidation
Proceeding in respect of either Company or any other Grantor; or

                  (e) any other circumstances which otherwise might constitute a
defense available to, or a discharge of, either Company or any other Grantor in
respect of the Senior Lender Claims, or of the Trustee or any Noteholder in
respect of this Agreement.

                  SECTION 8.   MISCELLANEOUS.

                  8.1      Conflicts. In the event of any conflict between the
provisions of this Agreement and the provisions of the Security Documents, the
Senior Loan Documents or the Noteholder Documents, the provisions of this
Agreement shall govern.

                  8.2      Continuing Nature of this Agreement; Severability.
This Agreement shall continue to be effective until the later of (a) the date on
which the Discharge of Senior Lender Claims shall have occurred and (b) the
indefeasible payment in full of the Noteholder Claims. The Senior Lenders may
continue, at any time and without notice to the Trustee or any Noteholder, to
extend credit and other financial accommodations and lend moneys to or for the
benefit of either Company or any Grantor constituting Senior Lender Claims on
reliance hereof. The Trustee, on behalf of itself and the Noteholders, hereby
waives any right it may have under applicable law to revoke this Agreement or
any of the provisions of this Agreement. The terms of this Agreement shall
survive, and shall continue in full force and effect, in any Insolvency or
Liquidation Proceeding. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall not invalidate the remaining provisions
hereof, and any such prohibition or unenforceability in any jurisdiction shall
not invalidate or render unenforceable such provision in any other jurisdiction.

                  8.3      Amendments; Waivers. With the written consent of the
Instructing Group, the Collateral Agent and the Companies may from time to time
amend, supplement or waive any provision hereof; provided that no such
amendment, supplement or waiver shall, without the written consent of the
Trustee, materially adversely affect the rights of the Noteholders. The
Companies and other Grantors shall not have any right to consent to or approve
any amendment, modification or waiver of any provision of this Agreement except
to the extent their rights are directly affected. The Companies hereby agree to
execute and deliver any supplement or amendment to this Agreement or the
Security Documents or any

                                       20

other document or instrument necessary to evidence the appointment of a
successor Collateral Agent pursuant to Section 2.3.

                  8.4      Information Concerning Financial Condition of the
Companies and the Subsidiaries. The Senior Lenders and their Representatives, on
the one hand, and the Trustee and the Noteholders, on the other hand, shall each
be responsible for keeping themselves informed of (a) the financial condition of
the Companies and the Subsidiaries and all endorsers and/or guarantors of the
Noteholder Claims or the Senior Lender Claims and (b) all other circumstances
bearing upon the risk of nonpayment of the Noteholder Claims or the Senior
Lender Claims. The Collateral Agent and the Senior Lenders shall have no duty to
advise the Trustee or any Noteholder of information known to it or them
regarding such condition or any such circumstances or otherwise. In the event
the Collateral Agent or any of the Senior Lenders, in its or their sole
discretion, undertakes at any time or from time to time to provide any such
information to the Trustee or any Noteholder, it or they shall be under no
obligation (w) to make, and the Collateral Agent and the Senior Lenders shall
not make, any express or implied representation or warranty, including with
respect to the accuracy, completeness, truthfulness or validity of any such
information so provided, (x) to provide any additional information or to provide
any such information on any subsequent occasion, (y) to undertake any
investigation or (z) to disclose any information which, pursuant to accepted or
reasonable commercial finance practices, such party wishes to maintain
confidential or is otherwise required to maintain confidential.

                  8.5      Consent to Jurisdiction; Waivers. The parties hereto
consent to the jurisdiction of any state or federal court located in New York,
New York, and consent that all service of process may be made by registered mail
directed to such party as provided in Section 8.6 below for such party. Service
so made shall be deemed to be completed three days after the same shall be
posted as aforesaid. The parties hereto waive any objection to any action
instituted hereunder based on forum non conveniens, and any objection to the
venue of any action instituted hereunder. Each of the parties hereto waives any
right it may have to trial by jury in respect of any litigation based on, or
arising out of, under or in connection with this Agreement or any Security
Document, or any course of conduct, course of dealing, verbal or written
statement or action of any party hereto.

                  8.6      Notices. All notices to the Noteholders and the
Senior Lenders permitted or required under this Agreement may be sent to their
Representatives. Unless otherwise specifically provided herein, any notice or
other communication herein required or permitted to be given shall be in writing

courier service or U.S. mail and shall be deemed to have been given when

and the Noteholders, agrees that each of them shall take such further action and
shall execute and deliver to the Collateral Agent such additional documents and
instruments (in recordable form, if requested) as the Collateral Agent may
reasonably request to effectuate the terms of and the Liens contemplated by this
Agreement.
