entered into by and among TESORO PETROLEUM CORPORATION, a Delaware corporation
(the "Company"), The Frost National Bank, as the bank and the securities
intermediary (together with its permitted successors in such capacity, the
"Depositary Agent") and WILMINGTON TRUST COMPANY, as Collateral Agent (together
with its successors in such capacity, the "Collateral Agent").

with its successors in such capacity, the "Administrative Agent") and Goldman
Sachs Credit Partners L.P., as sole lead arranger, sole bookrunner and
syndication agent.

2. The Company has issued $375,000,000 in principal amount of 8.00% Senior
Secured Notes due April 15, 2008 (the "Initial Notes") pursuant to the Indenture
dated as of April 17, 2003 (the "Indenture") by and among the Company, the
Guarantors and The Bank of New York, as Trustee (together with its successors in
such capacity, the "Trustee").

3. Pursuant to the Term Loan Agreement, the Guarantors guarantee payment of the
Initial Term Loans and all other Term Loan Obligations. Pursuant to the
Indenture, the Guarantors guarantee payment of the Initial Notes and all other

4. The Term Loan Agreement and Indenture require the Company and the Guarantors
to secure payment of the Initial Term Loans and the Initial Notes and other
Secured Obligations, Equally and Ratably, by security interests in the
Collateral. Without providing any commitments to the Company as to the funding
of any future indebtedness, the Term Loan Agreement and Indenture permit the
Company from time to time to incur Indebtedness which it is otherwise permitted

Term Loans borrowed under the Term Loan Agreement or additional Notes issued
under the Indenture (or both) and to secure such additional Term Loans and

principal amount (including the Initial Term Loans and the Initial Notes) not
exceeding $725,000,000 at any one time outstanding.

5. The Term Loan Agreement and Indenture further require that such security
interests in the Collateral be granted pursuant to the Security Documents to a
collateral agent acting for the benefit of the holders of Term Loans, Notes and
other Secured Obligations. This Agreement sets forth the terms on which the
Collateral Agent has undertaken to accept, hold and enforce such security
interests and all related rights, interests and powers as agent for, and for the
benefit exclusively of, the present and future holders of the Term Loans, Notes
and other Secured Obligations.

                           with such proposed project and, if clause (II) above
                           is applicable, in accordance with the budget referred
                           to in clause (II) above;

                  (b) Application of Permitted Investments. Permitted
Investments, if any, purchased upon the direction of the Company under the
provisions of this Agreement shall be deemed at all times to be a part of the
Asset Sale Proceeds Account from which funds were withdrawn in order to acquire
the Permitted Investment and shall be deemed to constitute funds on deposit in
and credited to the Asset Sale Proceeds Account, and the income or interest
earned and gains realized in excess of losses suffered by the Asset Sale
Proceeds Account due to the investment of funds deposited therein shall be
credited and retained in the Asset Sale Proceeds Account, except as otherwise
expressly provided by the terms hereof.

                  (c) Earnings. All earnings, if any, on funds in the Asset Sale
Proceeds Account maintained hereunder shall be credited to the Company for tax
reporting purposes. The Depositary Agent shall provide to the Company a
statement with respect to all interest earned on the Asset Sale Proceeds Account
as of the close of each calendar year for which income is earned on the Asset
Sale Proceeds Account. The Company shall provide the Depositary Agent with its
taxpayer identification number, documented, to the extent necessary, by an
appropriate executed Form W-9, upon execution of this Agreement. This form
shall, to the extent necessary, be renewed as required by the Internal Revenue
Service and provided to the Depositary Agent. The Depositary Agent shall be
entitled to rely on an opinion of legal counsel (which may be counsel to the
Company) in connection with the reporting of any earnings with respect hereto.

                  (d) Liquidation of Investments for Distributions. The
Collateral Agent is hereby authorized to direct the Depositary Agent, in writing
using the form attached hereto as Exhibit A, to liquidate or direct the
liquidation of any Permitted Investment (without regard to maturity) in order to
make or cause to be made any application required by any Section of this Article
2. In furtherance, and not in limitation, of any other indemnity or limitation
of liability with respect to the Collateral Agent contained herein or in any
other Term Loan Document or Note Document, the Collateral Agent and the
Depositary Agent shall in no way be liable for any losses suffered by the
Company, including losses due to early liquidation or market risk, which are a
result of the Collateral Agent's exercise of its authority under this provision.

                  (e) Value of Permitted Investments. Permitted Investments, if
any, credited to the Asset Sale Proceeds Account shall be valued at their
current market value.

SECTION 2.03. Monies Received by the Company. In the event that the Company or
any Guarantor receives any cash or Cash Equivalents constituting Net Sale
Consideration (including any Loss Proceeds) or other amounts required by the
terms hereof to be deposited into the Asset Sale Proceeds Account, the Company
shall, or shall cause such Guarantor to, hold the same in precisely the form
received in trust for and on behalf of the Secured Parties, segregated from
other funds of the Company or such Guarantor, and without any notice or demand
whatsoever, shall promptly deliver the same to the Depositary Agent for
application in accordance with the terms of this Agreement. No balance in, or
financial asset or other asset credited to, the Asset



                                       6
<PAGE>

Sale Proceeds Account maintained hereunder shall be disbursed or transferred by
the Depositary Agent, except in accordance with the provisions hereof.

SECTION 2.04. Books of Asset Sale Proceeds Account; Statements. The Depositary
Agent shall maintain books of account on a cash basis and record therein all
deposits into and transfers to and from the Asset Sale Proceeds Account and all
investment transactions effected by the Depositary Agent pursuant to the terms
hereof, and any such recordation shall constitute prima facie evidence of the
information recorded. Not later than the tenth Business Day of each month or as
soon as practicable thereof, but in no event later than the twentieth calendar
day of each month, commencing with the first month to occur after the earliest
of the receipt of Net Sale Consideration into the Asset Sale Proceeds Account in
accordance with the terms hereof, the Depositary Agent shall deliver to the
Company a statement setting forth the transactions in the Asset Sale Proceeds
Account during the preceding month (including deposits, withdrawals and
transfers from and to the Asset Sale Proceeds Account) and specifying the Net
Sale Consideration, Permitted Investments and other amounts held in or credited
to the Asset Sale Proceeds Account at the close of business on the last Business
Day of the preceding month. In addition, the Depositary Agent shall promptly
respond (during normal business hours) to requests by the Company for
information regarding deposits, investments and transfers into, in respect of
the Asset Sale Proceeds Account.

Account as set forth and defined in this Agreement.

                  (b) Agreement. Each of the parties hereto agrees that:

                       (i) the Asset Sale Proceeds Account will be maintained,
         to the extent that "financial assets" (within the meaning of Section
         8-102(a)(9) of the UCC, and as so defined the term financial asset is
         so used throughout this Agreement) are deposited therein or credited
         thereto, as a "securities account" (within the meaning of Section 8-501
         of the UCC), and, to the extent that credit balances not constituting
         financial assets are credited thereto, as a "deposit account" (within
         the meaning of Section 9-102(a)(29) of the UCC);

                       (ii) the Company is an "entitlement holder" (within the
         meaning of Section 8-102(a)(7) of the UCC) in respect of any "financial
         assets" credited to the Asset Sale Proceeds Account;


                                       7
<PAGE>

                       (iii) all property (including a security, security
         entitlement, investment property, instrument or obligation, share,
         participation, interest, cash or other property whatsoever) delivered
         to the Depositary Agent will be promptly credited by the Depositary
         Agent to the Asset Sale Proceeds Account by an appropriate entry in its
         records in accordance with this Agreement;

                       (iv) all financial assets and other assets in registered
         form or payable to or to order and credited to the Asset Sale Proceeds
         Account shall be registered in the name of, payable to or to the order
         of, or specially endorsed to, the Depositary Agent or in blank, or
         credited to another securities account maintained in the name of the
         Depositary Agent, and in no case will any such financial asset or other
         asset be credited to the Asset Sale Proceeds Account at any time, if,
         at such time, such asset is registered in the name of, payable to or to
         the order of, or endorsed to, the Collateral Agent (in such capacity)
         or the Company, except to the extent the foregoing have been
         subsequently endorsed by the Collateral Agent (in such capacity) or the
         Company to the Depositary Agent or in blank;

                       (v) the Depositary Agent is acting as "securities
         intermediary" (within the meaning of Section 8-102(a)(14) of the UCC)
         with respect to the Asset Sale Proceeds Account and financial assets
         deposited therein or credited thereto and as a "bank" (within the
         meaning of Section 9-304 of the UCC) with respect to the Asset Sale
         Proceeds Account and credit balances not constituting financial assets
         credited thereto; and

                       (vi) the Depositary Agent shall not change the name or
         account number of the Asset Sale Proceeds Account without the prior
         written consent of the Collateral Agent.

SECTION 3.02. Certain Rights and Powers in Respect of Asset Sale Proceeds
              Account and Funds.

                  (a) Rights to Asset Sale Proceeds Account. The Company shall
not make, attempt to make or consent to the making of any withdrawal or transfer
from the Asset Sale Proceeds Account except in strict adherence to the terms and
conditions of this Agreement. The Company shall not have any rights or powers
with respect to the remittance of amounts credited to, the disbursement of
credited amounts out of, or the investment of credited amounts in, the Asset
Sale Proceeds Account, except to have amounts credited thereto applied in
accordance with this Agreement; provided, however, that the parties hereto
acknowledge and agree that the foregoing provisions of this Section 3.02(a)
shall not be deemed to divest the Company of its interest as an "entitlement
holder" under the UCC, as provided in this Agreement.

                  (b) Certain Powers of the Collateral Agent and the Depositary
Agent. The Collateral Agent and, where appropriate, the Depositary Agent will
have the right, but not the obligation, to (i) refuse any item for credit to the
Asset Sale Proceeds Account except as required by the terms of this Agreement
and (ii) refuse to honor any request for transfer on the Asset Sale Proceeds
Account which is not consistent with this Agreement. If the Company fails to
perform


                                       8
<PAGE>

any agreement contained herein and such failure to perform is continuing for a
period of 30 days, the Collateral Agent may itself perform, or cause the
performance of, such agreement, and the expenses of the Collateral Agent
incurred in connection therewith shall be payable by the Company upon written
demand. The Company hereby irrevocably appoints the Collateral Agent as the
Company's attorney-in-fact, with full authority in the place and stead of the
Company, and in the name of the Company or otherwise from time to time in the
Collateral Agent's discretion, if an Event of Default shall have occurred and be
continuing, to take any action and to execute any instrument which the
Collateral Agent may deem necessary or advisable to accomplish the purposes of
this Agreement, including:

                       (i) to ask, demand, collect, sue for, recover,
         compromise, receive and give acquittance and receipts for moneys due
         and to become due under or in respect of any of the Asset Sale Proceeds
         Account or the proceeds of financial assets or other assets held
         therein or credited thereto;

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

                       (iii) to file any claims or take any action or institute
         any proceedings which the Collateral Agent may deem necessary or
         desirable for the collection of any of the Asset Sale Proceeds Account
         or the proceeds of financial assets or other assets held therein or
         credited thereto or otherwise to enforce the rights of the Collateral
         Agent with respect to the Asset Sale Proceeds Account or the proceeds
         of financial assets or other assets held therein or credited thereto,
         provided that, with respect to this clause (iii), such rights shall be
         exercised in accordance with Section 3.06; and

                       (iv) to perform the affirmative obligations of the
         Company hereunder if, and to the extent that, the Company fails to
         perform such obligations and such failure to perform is continuing for
         a period of 30 days.

The Company hereby acknowledges, consents and agrees that the power of attorney
granted pursuant to this Section 3.02(b) is irrevocable and coupled with an
interest. The powers conferred on the Collateral Agent hereunder are solely to
protect its interest (on behalf of the applicable Secured Parties) in the Asset
Sale Proceeds Account and the proceeds of financial assets and other assets held
therein or credited thereto and shall not impose any duty on the Collateral
Agent to exercise any such powers. Except for the reasonable care of the Asset
Sale Proceeds Account in its possession or under its control (as the case may
be) and the accounting for moneys actually received by it hereunder, neither the
Depositary Agent nor the Collateral Agent shall have any duty as to the Asset
Sale Proceeds Account or the proceeds of financial assets or other assets held
therein or credited thereto, or as to the taking of any necessary steps to
preserve rights against prior parties or any other rights pertaining to the
Asset Sale Proceeds Account or proceeds. Each of the Depositary Agent and the
Collateral Agent is required to exercise reasonable care in the custody and
preservation of the Asset Sale Proceeds Account and the financial assets and
other assets held therein or credited thereto in its possession or under its
control (as the case may be); provided, however, that the Collateral Agent in
any event shall be


                                       9
<PAGE>

deemed to have exercised reasonable care in the custody and preservation of the
Asset Sale Proceeds Account if it takes such action for that purpose as the
Company reasonably requests in writing at times other than upon the occurrence
and during the continuance of any Event of Default, but, notwithstanding the
foregoing, the failure of the Collateral Agent to comply with any such request
at any time shall not in itself be deemed a failure to exercise reasonable care.

SECTION 3.03. Security Interest.

                  (a) Grant. To secure the timely payment in full in cash and
performance in full of the Secured Obligations of the Company, the Company does
hereby assign, grant, hypothecate and pledge to, and grant a first priority
security interest in favor of the Collateral Agent, on behalf of and for the
sole and exclusive benefit of the Secured Parties on all the estate, right,
title, interest and security entitlements of the Company, whether now owned or
hereafter acquired, in the Asset Sale Proceeds Account and in all cash, cash
equivalents, instruments, investments, other securities, financial assets and
other assets held therein or credited thereto and all proceeds thereof,
including all rights of the Company to receive moneys due in respect of such
Asset Sale Proceeds Account, all claims with respect to such Asset Sale Proceeds
Account, all income or gain earned in respect of the financial assets and other
assets held in or credited to such Asset Sale Proceeds Account, and all proceeds
receivable or received when any financial asset or other asset held in or
credited to an Asset Sale Proceeds Account is collected, exchanged or otherwise
disposed of, whether voluntarily or involuntarily.

                  (b) Acknowledgment. The Depositary Agent hereby acknowledges
the first priority security interest in, and the pledge by the Company to the
Collateral Agent for the benefit of the Secured Parties of all of the Company's
assets held in or credited to the Asset Sale Proceeds Account and all proceeds
thereof, and will so indicate on the records maintained by the Depositary Agent
with respect to the Asset Sale Proceeds Account. The Depositary Agent agrees to
hold all such assets for the purposes of, and on the terms set forth in, this
Agreement.

                  (c) Other Liens; Adverse Claim.

                       (i) The Company represents and warrants that:

                           (A) it has not assigned any of its rights under the
                  Asset Sale Proceeds Account;

                           (B) it has not executed and is not aware of any
                  effective financing statement, security agreement, control
                  agreement or other instrument similar in effect covering all
                  or any part of the Asset Sale Proceeds Account except in favor
                  of the Collateral Agent; and

                           (C) it has full power and authority to grant a
                  security interest in and assign its right, title and interest
                  in the Asset Sale Proceeds Account and all financial assets
                  and other assets held therein or credited thereto and all
                  proceeds thereof hereunder.


                                       10
<PAGE>

                       (ii) The Company represents, warrants and covenants that
         it has not granted, and shall not grant, to any Person other than the
         Collateral Agent any interest in Asset Sale Proceeds Account and that
         it has kept, and shall keep, the Asset Sale Proceeds Account free from
         all Liens other than Permitted Liens.

                       (iii) The Depositary Agent represents and warrants that
         it has no knowledge (without having conducted an independent
         investigation) of any Lien on the Asset Sale Proceeds Account other
         than the claims and interest of the parties hereto as provided herein.
         In the event that the Depositary Agent has or subsequently obtains by
         agreement, operation of law or otherwise a security interest in the
         Asset Sale Proceeds Account or any financial asset or other asset
         credited thereto, the Depositary Agent hereby agrees that such security
         interest shall be subordinate to the security interest of the
         Collateral Agent for the benefit of the Secured Parties.

                       (iv) Each of the Collateral Agent and the Depositary
         Agent represents and warrants that it has no notice (without having
         conducted an independent investigation) of any adverse claim to the
         financial assets or other assets deposited in or credited to the Asset
         Sale Proceeds Account or to security entitlements with respect thereto.

                       (v) The financial assets and other assets credited to the
         Asset Sale Proceeds Account shall 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 as set forth in clause (vi) below.

                       (vi) The Company authorizes the Depositary Agent to debit
         its primary account number 01-0322466 to pay for all usual and
         customary service charges, transfer fees and account maintenance fees
         of the Depositary Agent in connection with the Asset Sale Proceeds
         Account. If the Company has insufficient funds in its primary account
         to pay such charges and fees, the Depositary Agent may thereafter
         exercise its right of set-off against amounts on deposit in the Asset
         Sale Proceeds Account, but only to the extent of such fees in respect
         of the Asset Sale Proceeds Account.

SECTION 3.04. Duties and Certain Rights of Depositary Agent.

                  (a) General. The duties of the Depositary Agent shall be
determined solely by the express provisions of this Agreement and by applicable
law and no duties, implied covenants or obligations shall be read into this
Agreement against the Depositary Agent as depositary agent, securities
intermediary and bank.

                  (b) Acceptance of Appointment. The Depositary Agent hereby
agrees to act as depositary agent and securities intermediary with respect to
the Asset Sale Proceeds Account and pursuant to this Agreement. The other
parties hereto hereby acknowledge that the Depositary Agent shall act as
depositary agent, securities intermediary and bank with respect to the Asset
Sale Proceeds Account and pursuant to this Agreement.


                                       11
<PAGE>

                  (c) Financial Assets Election. The Depositary Agent hereby
agrees that each item of property (including a security, security entitlement,
investment property, instrument or obligation, share or participation) credited
to the Asset Sale Proceeds Account shall be treated as a financial asset under
Article 8 of the UCC other than cash from time to time and at any time deposited
in the Asset Sale Proceeds Account, and interest accrued or paid thereon.

                  (d) Negative Pledge. Subject to the terms of this Agreement,
the Depositary Agent hereby agrees that it shall not grant any Lien in the
financial assets and other assets that it is obligated to maintain under this
Agreement.

                  (e) Entitlement Orders, Instructions. If at any time the
Depositary Agent shall receive any entitlement order, instruction or any other
order from the Collateral Agent directing the transfer or redemption of any
financial asset or other asset relating to the Asset Sale Proceeds Account, or
directing the disposition of any funds in the Asset Sale Proceeds Account, the
Depositary Agent shall comply with such entitlement order, instruction or other
order without further consent by the Company or any other Person. The parties
hereto agree that until the Depositary Agent's obligations under this Agreement
shall terminate in accordance with the terms hereof, the Collateral Agent shall
have control of each of the Company's security entitlements with respect to the
financial assets and other assets credited to the Asset Sale Proceeds Account;
provided, however, that the Company, as the entitlement holder with respect to
the financial assets credited to the Asset Sale Proceeds Account and the Person
for whom the Asset Sale Proceeds Account are maintained, is entitled, subject to
Section 2.02 and the other provisions of this Agreement, to make substitutions
for the security entitlements with respect to the financial assets credited to
the Asset Sale Proceeds Account. The Depositary Agent hereby represents that it
has not entered into, and agrees that, until the termination of this Agreement
and the other Term Loan Documents or Note Documents in accordance their terms,
it will not enter into, any agreement with any other Person in respect such
Asset Sale Proceeds Account pursuant to which it would agree to comply with
entitlement orders made by such Person.

                  (f) Degree of Care. The Depositary Agent shall exercise due
care in accordance with reasonable commercial standards in administering the
Asset Sale Proceeds Account, accounting for assets credited to the Asset Sale
Proceeds Account and performing its duties as a bank with respect to the Asset
Sale Proceeds Account, and to the extent that any "investment property" is on
deposit, accounting for financial assets and other assets credited to the Asset
Sale Proceeds Account and performing its duties as securities intermediary with
respect to the Asset Sale Proceeds Account and, in each case, such assets
deposited therein or credited thereto and the credit balances credited thereto
under this Agreement.

                  (g) Action Upon Notices; Exercise of Judgment. The Depositary
Agent shall be permitted to conclusively rely and act upon any notice,
entitlement order, instruction, request, waiver, consent, receipt or other paper
or document whether in its original or facsimile form reasonably believed by the
Depositary Agent to be signed by the Collateral Agent, the Company or any other
authorized Person. The Depositary Agent shall not be liable for any error of
judgment or for any act done or step taken or omitted by it in good faith or for
any mistake of fact or law or for anything which the Depositary Agent may do or
refrain from doing in


                                       12
<PAGE>

connection herewith, except its own gross negligence or willful misconduct. The
Depositary Agent shall have duties only to the Collateral Agent (on behalf of
the Secured Parties).

                  (h) Indemnification and Liability. In consideration of the
appointment of Depositary Agent, the Company agrees:

                       (i) to fully indemnify and hold the Depositary Agent and
         each Affiliate, officer, director, shareholder, employee and agent of
         the Depositary Agent (each, an "Indemnified Person") harmless from and
         against any and all claim, loss, liability, damage, cost or expense
         (including reasonable legal fees and expenses) incurred by the
         Indemnified Person by reason of or resulting from this Agreement
         (including its having accepted such appointment or by reason of its
         carrying out of any of the terms of this Agreement); and

                       (ii) to reimburse each Indemnified Person for all its
         expenses, including reasonable fees and expenses of counsel and court
         costs incurred by reason of any position or action taken by the
         Indemnified Person pursuant to this Agreement or in connection with any
         action brought to interpret or enforce the provisions of this Agreement
         or any part thereof;

except, with respect to each of clauses (i) and (ii), to the extent that any
such claim, loss, liability, damage, cost or expense is determined by a court of
competent jurisdiction in a final non-appealable judgment to have been caused by
the Indemnified Person's gross negligence or willful misconduct. The parties
hereto hereby agree that no Indemnified Person shall be liable to such parties
for any actions taken by any Indemnified Person pursuant to and in compliance
with the terms hereof except in respect of any liability or expenses incurred by
the Indemnified Person arising from its gross negligence or willful misconduct.
Any Indemnified Person may consult with legal counsel of its selection in the
event of any dispute or question as to the construction of this Agreement or the
Indemnified Person's duties hereunder, and the Indemnified Person shall incur no
liability and shall be fully protected in acting in accordance with the opinion
and instructions of such counsel.

                  (i) Court Orders. The Depositary Agent is hereby authorized,
in its exclusive discretion, to obey and comply with all writs, orders,
judgments or decrees issued by any court or administrative agency affecting the
Asset Sale Proceeds Account or any financial asset credited to the Asset Sale
Proceeds Account. The Depositary Agent shall not be liable to any of the parties
hereto, their successors or assigns by reason of the Depositary Agent's
compliance with such writs, orders, judgments or decrees, notwithstanding that
such writ, order, judgment or decree may later be reversed, modified, set aside
or vacated.

                  (j) Resignation and Termination.

                       (i) The Depositary Agent may at any time resign by giving
         notice to each other party to this Agreement, such resignation to be
         effective upon the appointment of a successor Depositary Agent as
         provided below. The Collateral Agent may remove


                                       13
<PAGE>

         the Depositary Agent at any time by giving notice to each other party
         to this Agreement, such removal to be effective upon the appointment of
         a successor Depositary Agent as provided below.

                       (ii) In the event of any removal of the Depositary Agent,
         a successor Depositary Agent, which shall be a bank or trust company
         organized under the laws of the United States of America or of the
         State of New York capable of acting as a "securities intermediary"
         (within the meaning of Section 8-102(a)(14) of the UCC) and a "bank"
         (within the meaning of Section 9-102(a)(8) of the UCC), having a
         corporate trust office in New York, New York and a capital and surplus
         of not less than $50,000,000, shall be appointed by the Collateral
         Agent upon agreement by the Company, and such agreement shall not be
         unreasonably withheld. If a successor Depositary Agent shall not have

                       (ii) All written directions and instructions (which may
         be provided by facsimile transmission) by the Company or the Collateral

         provided for herein or otherwise available to it, all the rights and
         remedies of a secured party on default under the UCC at that time and
         consistent with the provisions of the other Term Loan Documents or Note
         Documents, including the right to proceed to protect and enforce the
         rights vested in it by this Agreement, to sell, liquidate or otherwise
         dispose of the Asset Sale Proceeds Account, and to cause the Asset Sale
         Proceeds Account to be sold, liquidated or otherwise disposed of, in
         each case in such manner as the Collateral Agent may elect; and

                       (ii) the proceeds of any financial assets and other
         assets credited to or held in the Asset Sale Proceeds Account and all

         of, collection from or other realization upon all or any part of the
         Asset Sale Proceeds Account may, in the discretion of the Collateral
         Agent, then or at any time thereafter, be applied (after payment of any
         amounts payable to the Depositary Agent pursuant to the terms hereof)
         in whole or in part by the Collateral Agent against all or any part of
         the Secured Obligations of the Company in accordance with the
         Collateral Agency Agreement.

No right, power or remedy herein conferred upon or reserved to the Collateral
Agent is intended to be exclusive of any other right, power or remedy and every
such right, power and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right, power and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder or otherwise shall not
prevent the concurrent assertion or employment of any other appropriate right or
remedy. Resort to any or all security now or hereafter held by the Collateral
Agent may be taken concurrently or successively and in one or several
consolidated or independent judicial actions or lawfully taken nonjudicial
proceedings, or both.

in order, among other things, to perfect its security interests in the Asset
Sale Proceeds Account, are powers coupled with an interest, and will neither be
affected by the bankruptcy of the Company nor by the lapse of time. Except as
otherwise provided herein, the obligations of the Depositary Agent hereunder
shall continue in effect until the security interests of the Collateral Agent in
the Asset Sale Proceeds Account have been terminated pursuant to the terms of
this Agreement, the other Term Loan Documents and Note Documents and the
Collateral Agent has notified the Depositary Agent of such termination in
writing.

SECTION 4.02. Secured Obligations. When each of the Term Loan Agreement and the
Indenture has expired or has otherwise terminated and all Secured Obligations of
the Company

have been paid in full, all commitments thereunder have terminated, all of the
Hedging Obligations owed to any Secured Party have terminated, all right, title
and interest of the Collateral Agent in the Asset Sale Proceeds Account shall be

in writing using the form attached hereto as Exhibit A to, and upon such
notification the Depositary Agent shall, pay any amounts (including Permitted
Investments) then remaining in the applicable Asset Sale Proceeds Account to the
Company. No termination of any interest of a Secured Party hereunder shall
affect the rights of any other Secured Party hereunder.

expenses and indemnification obligations, including Section 3.04(h) and the
provisions set forth in Sections 3.04(j) and 5.14, and in the event that the
Depositary Agent resigns in accordance with Section 3.04(j)(iii) or 3.04(j)(iv),
Article 2 shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the expiration or
termination of the Term Loan Agreement or the Indenture, the payment in full of
all Secured Obligations, the termination of any commitments thereunder, or the
termination of this Agreement or any provision hereof.

engage or be interested in any financial or other transactions with any party to
this Agreement and may act on, or as depositary, trustee or agent for, any
committee or body of holders of obligations of such Persons as freely as if it
were not the Depositary Agent hereunder. The Depositary Agent shall not be
obligated to take any action which in its reasonable judgment would involve it
in expense or liability unless it has been furnished with an indemnity
reasonably satisfactory to it. The Depositary Agent shall act as an agent only
and shall not be responsible or liable in any manner for soliciting any funds or
for the sufficiency, correctness, genuineness or validity of any funds or
securities deposited with or held by it, except in the case of its gross

effectiveness of the provisions thereof and as to the truth of any information
contained therein, which the Depositary Agent in good faith believes to be
genuine. The Depositary Agent shall not be liable for any error of judgment or
for any act done or step taken or omitted except in the case of its gross

and the advice or opinion of such counsel shall be full and complete
authorization and protection in respect of any action taken suffered or omitted
by it hereunder in good faith and reliance thereon.

SECTION 5.15. Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered shall be deemed an
original, but all such counterparts together shall constitute but one and the
same instrument. The delivery of an executed signature page of this Agreement by
facsimile transmission shall be effective as delivery of a manually executed
counterpart hereof.

SECTION 5.16. Effectiveness. This Agreement shall become effective upon the
execution of a counterpart hereof by each of the parties hereto and receipt by
the Company, the Depositary Agent and the Collateral Agent of written or
telephonic notification of such execution and authorization of delivery thereof.
