Mr. Dan D. Sandman

September 14, 2001

Dear Dan,

In consideration for your agreeing to serve as Vice Chairman and Chief Legal &
Administrative Officer of United States Steel Corporation, United States Steel
LLC and its successors (the "Corporation") agree to provide you with the
additional pension benefits outlined in paragraphs A. and B. of this agreement
("Agreement") upon your retirement if you are employed by the Corporation for a
period of at least five years following the date that USX Corporation is
separated into Marathon Oil Corporation and United States Steel Corporation
("Effective Date"). In the event of your death prior to retirement, the enhanced
pension benefits provided by this Agreement will be payable even if the
five-year service requirement has not been satisfied and will be calculated as
if the date of your retirement was the day immediately prior to the date of your
death.

A.   Enhanced Pension Benefits
     -------------------------

     The Corporation will provide a pension supplement to you upon your
     retirement from the Corporation (or to your surviving spouse and/or
     survivor upon your death prior to retirement) equal to the excess of (1)
     minus (2) below:

     (1)  the sum of the pension, surviving spouse's benefits, and/or survivor
          benefits which would be provided on your behalf under the United
          States Steel Corporation Plan for Non-Union Employee Pension Benefits
          (Revision of 1998) (or its successor) (hereinafter the "Plan") or the
          USX Corporation Non Tax-Qualified Pension Plan (or its successor)
          (hereinafter the "Non-Qualified Plan"), if such benefits were
          calculated using-

          (a)  your actual age at retirement (or death) plus three years, for
               purposes of applying the Plan's early retirement factors,

          (b)  your actual continuous service under the Plan for benefit accrual
               purposes at retirement (or death) plus three years, for purposes
               of determining your regular pension under the Final Earnings
               provisions of the Plan and for purposes of applying the Plan's
               early retirement factors,

          (c)  the interest rate and mortality table specified by the Plan for
               calculating lump sum distributions as of the date of your
               retirement (or death), except that the lump sum shall be at least
               equal to the amount that would be provided if the lump sum was
               calculated using the applicable interest rate and mortality table
               for retirements on the later of December 31, 2001 or the
               Effective Date,

          (d)  the actuarial factors and assumptions that are in effect under
               the Plan as of the later of December 31, 2001 or the Effective
               Date, using your actual age (and your spouse's and/or survivor's
               age) at retirement (or death),
<PAGE>

                                   [LOGO] USX

                                                                    [LETTERHEAD]

          (e)  the Rule-of-70/80 retirement provisions under the Plan even
               though the period of absence requirements have not been
               satisfied, and

          (f)  your actual age, except as specifically provided above, for
               purposes of determining the amount of your benefits under the
               Plan.

     (2)  the sum of the pension, surviving spouse's benefits, and/or survivor
          benefits which are actually payable on your behalf under the Plan or
          the Non-Qualified Plan as of your retirement (or death).

     For purposes of determining the amounts in (1) and (2) above, benefits will
     be based upon the amount of immediate pension payable in the form of a lump
     sum distribution under the terms of the applicable plan. To the extent a
     pension benefit is payable under this Agreement, it will be paid in the
     form of a lump sum distribution by the United States Steel Corporation (or
     its successor).

     You may elect, prior to retirement and in writing to the administrator of
     the Corporation's employee benefit plans, to receive such lump sum
     distribution either:
     (i)  in full on February 1 of the year following the year in which you
          retire, or
     (ii) in up to five annual installments with the first annual installments
          payable within 90 days following your date of retirement and the
          succeeding installments payable on the applicable anniversaries of the
          first payment date.

     Interest would accrue and be payable on the balance due at the rate used
     under the Plan to determine the actuarially equivalent lump sum value of
     participants' benefits under the Plan.

B.   Consent Requirements
     --------------------

     For purposes of the USX Corporation Executive Management Supplemental
     Pension Program and the USX Corporation Non Tax-Qualified Pension Program,
     you will be treated as having Company consent to retire even if you have
     not attained age 60 as of the date of your retirement.

Sincerely,

/s/ T.J. Usher

undivided percentage ownership interest in: (i) each Pool Receivable then
existing, (ii) all Related Security with respect to such Pool Receivables, and
(iii) all Collections with respect to, and other proceeds of, such Pool

     (d) (i) It is the express intent of the parties hereto that the transfers
of the Receivables, Related Security, Collections and other proceeds of such
Receivables by the Seller to the Collateral Agent, as contemplated by this
Agreement be, and be treated as, sales and not as secured loans secured thereby.
If, however, notwithstanding the intent of the parties, such transactions are
deemed to be loans, the Seller hereby grants to the Collateral Agent for the
benefit of the Purchasers (ratably, according to each

                                       4
<PAGE>

such Purchaser's Net Investment) a security interest (and hereby authorizes the
filing of all applicable financing statements to perfect such security interest)

Related Security and Collections now existing and hereafter created, all monies
due or to become due and all amounts received with respect thereto, and all
proceeds thereof, to secure the obligations of the Seller hereunder, and this
Agreement shall be deemed a security agreement under applicable law.

          (ii) In addition to and without limiting the grant of security
     interest described in clause (i), above, to secure all of the Seller's
                           ---------
     obligations (monetary or otherwise) under this Agreement and the other
     Transaction Documents to which it is a party, whether now or hereafter
     existing or arising, due or to become due, direct or indirect, absolute or
     contingent, the Seller hereby grants to the Collateral Agent for the
     benefit of the Purchasers (ratably, according to each such Purchaser's Net
     Investment) a security interest in all of the Seller's right, title and
     interest, if any, (including any undivided interest of the Seller) in, to
     and under all of the following, whether now or hereafter owned, existing or
     arising: (i) all Pool Receivables, (ii) all Related Security with respect
     to such Pool Receivables, (iii) all Collections with respect to such Pool
     Receivables, (iv) the Lock-Box Accounts, the Concentration Account and the

in the Collection Account on any such Settlement Date to pay all of the above
amounts in full, the Collateral Agent shall pay such amounts to the applicable
Funding Agents in the order of priority set forth above, and with respect to any
such category above for which the Collateral Agent shall have insufficient funds
to pay all amounts owing on such date, ratably (based on the amounts in such
categories owing to such Persons) among all such Persons entitled to payment

                 -----------
action as it deems appropriate to avoid the need for, or reduce the amount of,
such compensation that would not be otherwise disadvantageous to such Affected
Person. For purposes of this Section 1.9, an Affected Person shall be deemed to
                             -----------
have promptly notified the Seller of an event if such notice is given to the
Seller within 6 months of the date such Affected Person obtains knowledge of
such event.

     Section 1.10. Requirements of Law. If any Affected Person reasonably
                   -------------------
determines that the existence of or compliance with: (a) any law or regulation
or any change therein or in the interpretation or application thereof, in each
case adopted, issued or occurring after the date hereof, or (b) any request,
guideline or directive from any central bank or other Governmental Authority
(whether or not having the force of law) issued or occurring after the date of
this Agreement:

          (i) subjects such Affected Person to any tax of any kind whatsoever
     with respect to this Agreement, any increase in the Purchased Interest or
     in the amount of Capital relating thereto, or does or shall change the
     basis of taxation of payments to such Affected Person on account of
     Collections, Discount or any other amounts payable hereunder (excluding
     taxes imposed on the overall pre-tax net income of such Affected Person,
     franchise taxes imposed on such Affected Person, by the jurisdiction under
     the laws of which such Affected Person is organized or a political
     subdivision thereof),

                                       14
<PAGE>

          (ii) imposes, modifies or holds applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by, or
     deposits or other liabilities in or for the account of, purchases, advances
     or loans by, or other credit extended by, or any other acquisition of funds
     by, any office of such Affected Person that are not otherwise included in
     the determination of the Eurodollar Rate or the Base Rate hereunder, or

          (iii) imposes on such Affected Person any other condition,

and the result of any of the foregoing is: (A) to increase the cost to such
Affected Person of acting as Collateral Agent or Funding Agent, or of agreeing
to purchase or purchasing or maintaining the ownership of undivided percentage
ownership interests with regard to the Purchased Interest (or interests therein)
or any Portion of Capital, or (B) to reduce any amount receivable hereunder
(whether directly or indirectly), then, in any such case, upon written demand by
such Affected Person (accompanied by the certificate referred to below, with a
copy to the applicable Funding Agent), the Seller shall promptly pay to such
Affected Person additional amounts necessary to compensate such Affected Person
for such additional cost or reduced amount receivable. All such amounts shall be
payable as incurred. A certificate from such Affected Person to the Seller
describing in reasonable detail the amount and basis for the amount of such
additional costs or reduced amount receivable shall be conclusive and binding
for all purposes, absent manifest error. Each Affected Person will promptly
notify the Seller of any event of which it has knowledge that will entitle such
Affected Person to compensation pursuant to this Section 1.10 and will use all
                                                 ------------
reasonable efforts to take such action as it deems appropriate to avoid the need
for, or reduce the amount of, such compensation that would not be otherwise
disadvantageous to such Affected Person. For purposes of this Section 1.10, an
                                                              ------------
Affected Person shall be deemed to have promptly notified the Seller of an event
if such notice is given to the Seller within 6 months of the date such Affected
Person obtains knowledge of such event.

     Section 1.11. Inability to Determine Eurodollar Rate. If any Funding Agent
                   --------------------------------------
shall have determined before the first day of any Settlement Period (which
determination shall be conclusive and binding upon the parties hereto), by
reason of circumstances affecting the interbank Eurodollar market, either that:
(a) dollar deposits in the relevant amounts and for the relevant Settlement
Period are not available, (b) adequate and reasonable means do not exist for
ascertaining the Eurodollar Rate for such Settlement

                                       15
<PAGE>

Period or (c) the Eurodollar Rate determined pursuant hereto does not accurately
reflect the cost to the applicable Affected Person (as conclusively determined
by such Funding Agent) of maintaining any Portion of Capital during such
Settlement Period, such Funding Agent shall promptly give telephonic notice of
such determination, confirmed in writing, to the Seller before the first day of
such Settlement Period. Upon delivery of such notice: (i) no Portion of Capital
shall be funded thereafter at the Alternate Rate determined by reference to the
Eurodollar Rate unless and until such Funding Agent shall have given notice to
the Seller that the circumstances giving rise to such determination no longer
exist, and (ii) with respect to any outstanding Portions of Capital then funded
at the Alternate Rate determined by reference to the Eurodollar Rate, such
Alternate Rate shall, on the immediately succeeding Settlement Date,
automatically be converted to the Alternate Rate determined by reference to the
Base Rate at the respective last days of the then-current Settlement Periods
relating to such Portions of Capital.

     Section 1.12. Sharing of Payments, etc. If any CP Conduit Purchaser or any
                   ------------------------
Committed Purchaser (for purpose of this Section 1.12 only, a "Recipient") shall
                                         ------------          ---------
obtain any payment (whether voluntary, involuntary, through the exercise of any
right of setoff, or otherwise) on account of any interest in the Purchased
Interest owned by it in excess of its ratable share thereof, such Recipient
shall forthwith purchase from the CP Conduit Purchasers and/or the Committed
Purchasers entitled to a share of such amount participations in the percentage
interests owned by such Persons as shall be necessary to cause such Recipient to
share the excess payment ratably with each such other Person entitled thereto;
provided, however, that if all or any portion of such excess payment is
--------  -------
thereafter recovered from such Recipient, such purchase from each such other
Person shall be rescinded and each such other Person shall repay to the
Recipient the purchase price paid by such Recipient for such participation to
the extent of such recovery, together with an amount equal to such other
Person's ratable share (according to the proportion of (a) the amount of such
other Person's required payment to (b) the total amount so recovered from the
Recipient) of any interest or other amount paid or payable by the Recipient in
respect of the total amount so recovered.

     Section 1.13. Expiration or Extension of Commitments. (a) the Seller may
                   --------------------------------------
request the extension of any Committed Purchaser's Commitment Expiry Date for an
additional three hundred and sixty four (364) days from time to time by
providing the applicable Funding Agent with a written request for such extension
no fewer than forty-five (45) days, but no more than sixty (60) days prior

                                       16
<PAGE>

to such Committed Purchaser's Commitment Expiry Date then in effect. The related
Funding Agent shall provide written notice to each other Funding Agent and the
Seller on or prior to the thirtieth (30th) day (the "Consent Date") following
                                                     ------------
the applicable Funding Agent's actual receipt of such written request for
extension of its desire to extend (any such Committed Purchaser an "Extending
                                                                    ---------
Committed Purchaser") or not to so extend (any such Committed Purchaser a
-------------------
"Non-Extending Committed Purchaser") such date.
 ---------------------------------

     (b) If Committed Purchasers holding less than 100% of the aggregate
Commitment of all Commitments consent to such extension, then the Seller may
elect by written notice to the Funding Agents to either:

          (i) continue this receivables financing facility for such additional
     period with an aggregate Commitment equal to the then effective aggregate
     Commitment less the Commitment of the Non-Extending Committed Purchaser(s);
     or

          (ii) require any such Non-Extending Committed Purchaser(s) and the
     related CP Conduit Purchaser(s) to execute a Transfer Supplement in
     accordance with Section 5.3 with respect to all of such Non-Extending
                     -----------
     Committed Purchaser(s)' Commitment and their other interests, rights and
     obligations under this Agreement to a Purchaser who consents thereto (in
     its sole discretion at such time) and shall assume such obligations upon
     its consent to assume such obligations; provided that (x) no such
                                             --------
     assignment shall conflict with any law, (y) such assignment shall be at the
     Seller's cost and expense, and (z) the purchase price to be paid to such
     Non- Extending Committed Purchaser shall be an amount equal to the Net
     Investment and accrued and unpaid Discount and Fees attributable to such
     Non-Extending Committed Purchaser and/or CP Conduit Purchaser.
     Notwithstanding anything in this Agreement to the contrary, such a transfer
     of a Non-Extending Committed Purchaser's interest and the related CP
     Conduit Purchaser's interest pursuant to a Transfer Supplement shall be
     subject to the consent of the Funding Agents (not to be unreasonably
     withheld).

     Section 1.14. Addition of Purchasers. The Seller may, with the written
                   ----------------------
consent of the Funding Agents (not to be unreasonably withheld), add additional
Persons as Purchasers (either to an existing group of related Purchasers or by
creating a new group of related Purchasers and a Funding Agent) or cause an
existing Purchaser to increase its Commitment in connection with a

                                       17
<PAGE>

corresponding increase in the Facility Limit; provided, however, that the
                                              --------  -------
Commitment of any Purchaser may only be increased with the consent of such
Purchaser. Each new Purchaser (or group of related Purchasers) and each
Purchaser increasing its Commitment shall become a party hereto or increase its
Commitment, as the case may be, by executing and delivering to each Funding
Agent and the Seller an Assumption Agreement (each, an "Assumption Agreement")
                                                        --------------------
in the form of Exhibit VI hereto (which Assumption Agreement shall, in the case
               ----------
of any new Purchaser or Purchasers be executed by each Person (including the
related Funding Agent) in such new Purchaser's group of related Purchasers).

     Section 1.15. Obligations Several. Each Committed Purchaser's obligation
                   -------------------
hereunder shall be several, such that the failure of any Committed Purchaser to
make a payment in connection with any purchase hereunder shall not relieve any
other Committed Purchaser of its obligation hereunder to make payment for any
purchase. Further, if any Committed Purchaser fails to satisfy its obligation to
make a purchase as required hereunder, upon receipt of notice of such failure
from the relevant Funding Agent, subject to the limitations set forth herein,
the non-defaulting Committed Purchasers in such defaulting Committed Purchaser's
group of related Purchasers shall purchase the defaulting Committed Purchaser's
portion of the related purchase pro rata in proportion to their relative
                                --- ----
Commitments (determined without regard to the Commitment of the defaulting
Committed Purchaser; it being understood that a defaulting Committed Purchaser's
                     -- ----- ----------
Commitment of any purchase shall be first put to the Committed Purchasers
related to such defaulting Purchaser and thereafter if there are no other
Committed Purchasers in such related group or if such other Committed Purchasers
are also defaulting Committed Purchasers, then such defaulting Committed
Purchaser's portion of such purchase shall be put to each other group of
Purchasers ratably and applied in accordance with this Section 1.15).
                                                       -------------
Notwithstanding anything in this Section 1.15 to the contrary, no Committed
                                 ------------
Purchaser shall be required to make a purchase pursuant to this paragraph for an
amount which would cause the aggregate Net Investment of such Committed
Purchaser (after giving effect to such purchase) to exceed its Commitment.

Party or Parties shall notify the Indemnifying Party or Parties in writing of

which such Indemnifying Party or Parties may have to such Indemnified Party or
Parties pursuant to Section 3.1 or 3.2, as applicable, unless and to the extent
                    -----------    ---

such Indemnifying Party or Parties and such Indemnified Party or Parties at such
Indemnifying Party's or Parties' cost, risk and expense. If (i) in the
reasonable opinion of such Indemnified Party or Parties, the engagement of such
counsel would present a conflict of interest that would prevent such counsel
from effectively undertaking such joint defense, (ii) such Indemnified Party or
Parties reasonably conclude that there may be legal defenses available to it or
them that are different from or in addition to those available to such
Indemnifying Party or Parties, (iii) such Indemnifying Party or Parties fail to
employ counsel reasonably satisfactory to such Indemnified Party or Parties in a
timely manner, or (iv) if a Termination Event or Unmatured Termination Event

parties to the same action, suit, proceeding, investigation or claim.

     (b) No Indemnifying Party shall (i) without the prior written consent of
the relevant Indemnified Party or Parties (which consent shall not be
unreasonably withheld or delayed) settle or compromise or consent to the entry

<PAGE>

     (c) USS acknowledges that, in making their decision to execute and deliver
this Agreement, the Collateral Agent, each Funding Agent and each Purchaser have
relied on USS's agreement to act as Servicer hereunder. Accordingly, USS agrees
that it will not voluntarily resign as Servicer.

     (d) The Servicer may with the prior written consent of the Funding Agents,
delegate its duties and obligations hereunder to any subservicer (each a
"Sub-Servicer"); provided, that, in each such delegation: (i) such Sub-Servicer

                  ----------------------
to be taken all such action as may be necessary or advisable to administer and
collect each Pool Receivable from time to time, all in accordance with this
Agreement and all applicable laws, rules and regulations, with reasonable care
and diligence, and in accordance with the Credit and Collection Policy. The
Servicer shall set aside, for the accounts of the Seller and the Purchasers, the
amount of the Collections to which each is entitled in accordance with Article
                                                                       -------
I. The Servicer may, in accordance with the Credit and Collection Policy, extend
-
the maturity of any Pool Receivable (but not beyond 60 days and not more than
once with respect to any such Pool Receivable) and extend the maturity or adjust
the Outstanding Balance of any Defaulted Receivable as the Servicer may
determine to be appropriate to maximize Collections thereof; provided, however,
                                                             --------  -------
that: (i) such extension or adjustment shall not alter the status of such Pool
Receivable as a Delinquent Receivable or a Defaulted Receivable or limit the
rights of the Purchasers, the Collateral Agent or the Funding Agents under this
Agreement and (ii) if a Termination Event has occurred and USS or an Affiliate
thereof is serving as the Servicer, USS or such Affiliate may make such
extension or adjustment only upon the prior written approval of the Funding
Agents. The Seller shall deliver to the Servicer and the Servicer shall hold for
the benefit of the Seller and the Collateral Agent (individually and for the
benefit of the Purchasers and the Funding Agents), in accordance with their

contrary contained herein, the Funding Agents may direct the Servicer (whether
the Servicer is USS or any other Person) to commence or settle any legal action
to enforce collection of any Pool Receivable or to foreclose upon or repossess
any Related Security; provided, however, that no such direction may be given
                      --------  -------
unless either: (A) a Termination Event has occurred or (B) any Funding Agent
believes in good faith that the failure to commence, settle or effect such legal
action, foreclosure or repossession could adversely affect Receivables
constituting a material portion of the Pool Receivables.

     (b) The Servicer shall, as soon as practicable following actual receipt of
collected funds, turn over the collections of any indebtedness that is not a

administering such collections. The Servicer, if other than USS or an Affiliate
thereof, shall, as soon as practicable upon demand, deliver to the Seller all
records in its possession that evidence or relate to any indebtedness that is

(i) the Facility Termination Date and (ii) the date on which all amounts
required to be paid to the Purchasers, the Funding Agents, the Collateral Agent,
and any other Indemnified Party or Affected Person hereunder shall have been
paid in full.

     After such termination, if USS or an Affiliate thereof was not the Servicer
on the date of such termination, the Servicer shall promptly deliver to the
Seller all books, records and related materials that the Seller previously
provided to the Servicer, or that have been obtained by the Servicer, in

Accounts into the Concentration Account.

     (b) Within 15 Business Days from the Closing Date, the Seller shall have
entered into a Concentration Account Agreement with the Concentration Account

investments shall mature not later than the Settlement Date immediately
succeeding such Permitted Investments and any such Permitted Investments shall
be credited to a securities account (as defined in the applicable UCC) over
which the Collateral Agent for the benefit of the Purchasers shall have a first
priority perfected Security interest. All income or other gain from investment
of monies deposited in the Concentration Account shall be deposited in the
Concentration Account immediately upon receipt thereof, and any loss resulting
from Permitted Investments shall be charged to the Concentration Account.

     (c) The Collateral Agent has established the Collection Account which shall
be used to accept the transfer of Collections of Pool Receivables from the
Concentration Account pursuant to Article I and for such other purposes

described in the Transaction Documents and the Collateral Agent with the consent
or at the direction of the Funding Agents shall have the exclusive right to
withdraw funds therefrom. On the date of the initial purchase hereunder, the
Seller (or the Servicer on its behalf) shall deposit into the Collection
Account, for the benefit of the Purchasers, an amount equal to $2,500,000; it
being understood that on each Settlement Date (until the day following the
Facility Termination Date when all amounts payable by the Seller or Servicer
hereunder have been paid in full), the Seller shall deposit into the Collection
Account, the amount, if any, necessary to cause the amount on deposit therein
(after giving effect to the transfers contemplated pursuant to Article I on such
                                                               ---------
date) equal to, at least, $2,500,000.

     So long as no Termination Event shall have occurred and be continuing, all
or any portion of the amounts on deposit in the Collection Account shall be
invested by the Collateral Agent at the Servicer's written direction in one or
more Permitted Investments. All income or other gain from investment of monies
deposited in the Collection Account shall be deposited in the Collection Account
immediately upon receipt thereof, and any loss resulting from Permitted
Investments shall be charged to the Collection Account. The maximum permissible
maturity of any Permitted Investment shall

                                       28
<PAGE>

be not later than the Settlement Date immediately succeeding such
Permitted Investment.

     (d) Upon the occurrence and during the continuation of a Termination Event,
the Collateral Agent with the consent or at the direction of the Funding Agents
may at any time thereafter give notice to each Lock-Box Bank, the Concentration
Account Bank and the Collection Account Bank that the Collateral Agent is
exercising its rights under the Lock-Box Letters, the Concentration Account
Agreement and the Collection Account Agreement, as applicable, to do any or all
of the following: (i) to have the exclusive ownership and control of the
Accounts transferred to the Collateral Agent and to exercise exclusive dominion
and control over the funds deposited therein, (ii) to have the proceeds that are
sent to the respective Accounts redirected pursuant to the Collateral Agent's
instructions, and (iii) to take any or all other actions permitted under the
applicable Lock-Box Letter, the Concentration Account Agreement and the
Collection Account Agreement, as applicable. The Seller hereby agrees that if
the Collateral Agent at any time takes any action set forth in the preceding
sentence, the Collateral Agent shall have exclusive control of the proceeds
(including Collections) of all Pool Receivables and the Seller hereby further
agrees to take any other action that the Collateral Agent or any Funding Agent
may reasonably request to transfer such control. Any proceeds of Pool
Receivables received by the Seller or the Servicer thereafter shall be sent
immediately to the Collateral Agent.

from any such Person, and (ii) each action taken by such Funding Agent has been

Agent hereafter taken, including any review of the affairs of the Seller,
Servicer or any Originator, shall be deemed to constitute any representation or
warranty by the Collateral Agent or such Funding Agent, as applicable. Each
Purchaser represents and warrants to the Collateral Agent and the Funding Agents
that, independently and without reliance upon the Collateral Agent, Funding
Agents or any other Purchaser and based on such documents and information as it
has deemed appropriate, it has made and will continue to make its own appraisal
of and investigation into the business, operations, property, prospects,
financial and other conditions and creditworthiness of the Seller, Servicer or
the Originators, and the Receivables and its own decision to enter into this
Agreement and to take, or omit, action under any Transaction Document. Except
for items specifically required to be delivered hereunder, the Collateral Agent
shall not have any duty or responsibility to provide any Funding Agent with any
information concerning the Seller, Servicer or the Originators or any of their
Affiliates that comes into the possession of the Collateral Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

banking, trust, debt, entity or other business with the Seller, USS, Servicer or
any Originator or any of their Affiliates. With respect to the acquisition of
the Eligible Receivables pursuant to this Agreement, each of the Funding Agents
and the Collateral Agent shall have the same rights and powers under this
Agreement as any Purchaser and may exercise the same as though it were not such
an agent, and the

                                       35

terms "Purchaser" and "Purchasers" shall include each of the Funding Agents and
the Collateral Agent in their individual capacities.

     Section 5.8. Indemnification. Each Committed Purchaser shall indemnify and
                  ---------------
hold harmless the Collateral Agent (but solely in its capacity as Collateral
Agent) and its officers, directors, employees, representatives and agents (to
the extent not reimbursed by the Seller or Servicer and without limiting the
obligation of the Seller or Servicer to do so), ratably in accordance with their
respective Commitments from and against any and all liabilities, obligations,
losses, damages, penalties, judgments, settlements, costs, expenses and
disbursements of any kind whatsoever (including in connection with any
investigative or threatened proceeding, whether or not the Collateral Agent or
such Person shall be designated a party thereto) that may at any time be imposed
on, incurred by or asserted against the Collateral Agent or such Person as a
result of, or related to, any of the transactions contemplated by the
Transaction Documents or the execution, delivery or performance of the
Transaction Documents or any other document furnished in connection therewith
(but excluding any such liabilities, obligations, losses, damages, penalties,
judgments, settlements, costs, expenses or disbursements resulting solely from
the gross negligence or willful misconduct of the Collateral Agent or such
Person as finally determined by a court of competent jurisdiction); provided,
                                                                    --------
that in the case of each Purchaser that is a commercial paper conduit, such
indemnity shall be provided solely to the extent of amounts received by such
Purchaser under this Agreement which exceed the amounts required to repay such
Purchaser's outstanding Notes. Notwithstanding anything in this Section 5.8 to
                                                                -----------
the contrary, each of the Collateral Agent, each Funding Agent and each
Purchaser hereby covenants and agrees that it shall not institute against, or
join any other Person in instituting against, any CP Conduit Purchaser any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding or
other proceedings under any federal or state bankruptcy or similar law, for one
year and a day after the latest maturing Note issued by such CP Conduit
Purchaser is paid in full.

                  --------------------------
least thirty (30) days notice to the Seller and each Purchaser and Funding
Agent, resign as Collateral Agent. Such resignation shall not become effective
until a successor Collateral Agent is appointed by the Funding Agents (and,
unless such appointment is to an existing Funding Agent or Purchaser, such
successor Collateral Agent has been consented to by the Seller, such consent not
to be unreasonably withheld) and has accepted such

                                       36

appointment. Upon such acceptance of its appointment as Collateral Agent
hereunder by a successor Collateral Agent, such successor Collateral Agent shall
succeed to and become vested with all the rights and duties of the retiring
Collateral Agent, and the retiring Collateral Agent shall be discharged from its

and this Article V shall inure to its benefit as to any actions taken or omitted
         ---------
to be taken by it while it was the Collateral Agent.

                                  ARTICLE VI.
                                 MISCELLANEOUS

     Section 6.1. Amendments, Etc. No amendment or waiver of any provision of
                  ---------------
this Agreement or any other Transaction Document, or consent to any departure by
the Seller or the Servicer therefrom, shall be effective unless in a writing
signed by each Funding Agent, and, in the case of any amendment, by the other
parties thereto; and then such amendment, waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given;
provided, however, that, if required pursuant to the terms of any CP Conduit

Purchaser's securitization program, no such material amendment shall be
effective until both Moody's and Standard & Poor's have notified the applicable
Funding Agent in writing that such action will not result in a reduction or
withdrawal of the rating of any Notes of such CP Conduit Purchaser. No failure
on the part of the Purchasers or the Funding Agents to exercise, and no delay in
exercising any right hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any other right. The Collateral Agent shall
provide each Rating Agency with a copy of each amendment to or waiver or consent
under this Agreement promptly following the effective date thereof.

     Section 6.2. Notices, Etc. All notices and other communications provided

that neither the Seller nor the Servicer may assign any of its rights or
delegate any of its duties hereunder or under any of the other Transaction
Documents to which it is a party without the prior written consent of the
Funding Agents. Each CP Conduit Purchaser may assign, participate, grant
security interests in or otherwise transfer all or any portion of the Purchased
Interest held by it to any bank or other financial institution providing
liquidity support to such CP Conduit Purchaser in connection with its commercial
paper program (each, a "Liquidity Bank") or any other Program Support Provider
                        --------------
with respect to such CP Conduit Purchaser without prior notice to or consent
from the Seller, the Servicer, any Originator, any other party or any other
condition or restriction of any kind.

         -----------------
with prior or concurrent notice to the Seller, the Funding Agent for such CP
Conduit Purchaser and the Collateral Agent, assign all or any portion of such CP
Conduit Purchaser's interest in the Purchased Interest (and its related
Committed Purchasers) and its rights and obligations under this Agreement and
any other Transaction Document to which it is a party to a Conduit Assignee with
respect to such CP Conduit Purchaser. Upon such assignment by a CP Conduit
Purchaser to a Conduit Assignee, (A) the related administrative or managing
agent for such Conduit Assignee will act as the Funding Agent for such Conduit
Assignee hereunder, (B) such Conduit Assignee and its liquidity support
provider(s) and credit support provider(s) and other related parties shall have
the benefit of all the rights and protections provided to such CP Conduit
Purchaser and its related Committed Purchasers herein and in the other
Transaction Documents (including, without limitation, any limitation on recourse
against such Conduit Assignee), (C) such Conduit Assignee shall assume all of
such CP Conduit Purchaser's obligations hereunder or under any other Transaction

obligations, (D) all distributions to such CP Conduit Purchaser hereunder with
respect to the assigned portion of the CP Conduit Purchaser's interest shall be
made to such Conduit Assignee, (E) the definition of the term "CP Rate"

commercial paper issued by such Conduit Assignee (rather than such CP Conduit
Purchaser), (F) the defined terms and other terms and provisions of this
Agreement and other Transaction Documents shall be interpreted in accordance
with the foregoing, and (G) if requested by any Funding Agent or administrative
or managing agent with respect to the Conduit Assignee, the parties will execute
and deliver such further agreements and documents (including amendments to this
Agreement) and take such other actions as the Funding Agents or such
administrative agent may reasonably request to evidence and give effect to the
foregoing.

     (c) Participations. Any Committed Purchaser may, with the consent of the
         --------------
Funding Agents and in the ordinary course of its business and its accordance
with applicable law, at any time sell to one or more Persons (each, a
"Participant") participating interests in its rights and obligations hereunder
 -----------
and under the Transaction Documents. Notwithstanding any such sale by a
Committed Purchaser of participating interests to a Participant, such Committed
Purchaser's rights and obligations under this Agreement shall remain unchanged,
such Committed Purchaser shall remain solely responsible for the performance
hereof, and each CP Conduit Purchaser, the Collateral Agent and the Funding
Agents shall continue to deal solely and directly with such Committed Purchaser
in connection with such Committed Purchaser's rights and obligations under this
Agreement and the other Transaction Documents. Each Committed Purchaser agrees
that any agreement between such Committed Purchaser and any such Participant in
respect of such participating interest shall not restrict such Committed
Purchaser's right to agree to any amendment, supplement, waiver or modification
to this Agreement.

     (d) Assignments.
         -----------

     (i) Any Committed Purchaser may at any time and from time to time, upon the
prior written consent of the related CP Conduit Purchaser and the Funding
Agents, and, if the Purchaser is not an Affiliate of or otherwise related to the
selling Committed Purchaser and is not an existing Committed Purchaser, the
prior written consent of the Seller (which consent shall not be unreasonably
withheld), assign to one or more accredited investors or other Persons all or
any part of its rights and obligations under this Agreement and the other
Transaction Documents pursuant to a supplement to this Agreement, substantially
in the form of Exhibit VII hereto (each, a "Transfer Supplement"), executed by
               -----------                  -------------------

that (A) any such assignment cannot be for an amount less than the lesser of (1)
$10,000,000 and (2) such selling Committed Purchaser's Commitment and (B) each
Purchaser must be a financial institution with a short-term rating by the Rating
Agencies at least equal to the rating by each such Rating Agency on the Notes of
the related CP Conduit Purchaser.

     (ii) Each of the Committed Purchasers agrees that if it ceases to have
short-term debt ratings at least equal to the ratings then assigned to the Notes
of the related CP Conduit Purchaser by the Rating Agencies, or, if such
Committed Purchaser does not have short-term debt which is rated by the Rating
Agencies, in the event that the parent corporation of such Committed Purchaser
has rated short-term debt, such parent corporation ceases to have short-term
debt ratings at least equal to the ratings then assigned to the Notes of the
related CP Conduit Purchaser by the Rating Agencies (each, an "Affected
                                                               --------
Committed Purchaser"), such Affected Committed Purchaser shall be obliged, at
-------------------
the request of the related CP Conduit Purchaser and the related Funding Agent,
to assign all of its rights and obligations hereunder to (x) one or more other
Committed Purchasers selected by such CP Conduit Purchaser and the related
Funding Agent which are willing to accept such assignment, or (y) another
financial institution having short-term debt ratings at least equal to the
ratings then assigned to the Notes of the related CP Conduit Purchaser by the
Rating Agencies nominated by the related Funding Agent and consented to by such
CP Conduit Purchaser (which consent shall not be unreasonably withheld) and the
Collateral Agent, and willing to participate in this facility through the then
current scheduled Facility Termination Date in the place of such Affected
Committed Purchaser; provided that (i) the Affected Committed Purchaser receives
                     --------
payment in full of all outstanding Net Investment and accrued Discount, if any,
of such Person and any other amounts due and owning to such Affected Committed
Purchaser under this Agreement and the other Transaction Documents and (ii) such
nominated financial institution, if not an existing Committed Purchaser,
satisfies all the requirements of this Agreement.

     (iii) Upon (A) execution of a Transfer Supplement, (B) delivery of an
executed copy thereof to the related CP Conduit Purchaser, the Collateral Agent
and the Seller, (C) payment, if applicable, by the Purchaser to such selling
Committed Purchaser of an amount equal to the purchase price agreed between such
selling Committed Purchaser and the Purchaser and (D) if required by the
documents governing any applicable CP Conduit Purchaser's commercial paper
program, receipt by such CP Conduit Purchaser of confirmation from each Rating
Agency that such action will not

                                       40
<PAGE>

cause the downgrade or withdrawal of the then current rating on such CP Conduit
Purchaser's Notes, such selling Committed Purchaser shall be released from its
obligations hereunder to the extent of such assignment and the Purchasers shall,
for all purposes, be a Committed Purchaser party to this Agreement and shall
have all the rights and obligations of a Committed Purchaser under this
Agreement to the same extent as if it were an original party hereto, and no
further consent or action by the CP Conduit Purchasers, the Committed Purchasers
or the Funding Agents shall be required. The amount of the assigned portion of
the selling Committed Purchaser's share of the related Net Investment allocable
to the Purchaser shall be equal to the transferred percentage (as set forth in
the Transfer Supplement) of such selling Committed Purchaser's share of the
related Net Investment which is transferred thereunder regardless of the
purchase price paid therefor. Such Transfer Supplement shall be deemed to amend
this Agreement to the extent, and only to the extent, necessary to reflect the
addition of the Purchaser as a Committed Purchaser and the resulting adjustment
of the selling Committed Purchaser's Commitment arising from the purchase by the
Purchaser of all or a portion of the selling Committed Purchaser's rights,
obligations and interest hereunder.

     (e) Without limiting any other rights that may be available under
applicable law, the rights of the Purchasers hereunder may be enforced through
such Purchaser or by its agents.

contrary, no CP Conduit Purchaser shall, or shall be obligated to, pay any
amount, if any, payable by it pursuant to this Agreement or any other

which may be used to make such payment and which funds are not required to repay
Notes when due and (ii) after giving effect to such payment, either (x) such CP
Conduit Purchaser could issue Notes to refinance all outstanding Notes (assuming
such outstanding Notes matured at such time) in accordance with the program
documents governing such CP Conduit Purchaser's securitization program or (y)
all Notes of such CP Conduit Purchaser are paid in full. Any amount which such
CP Conduit Purchaser does not pay pursuant to the operation of the preceding
sentence shall not constitute a claim (as defined in Section 101 of the
Bankruptcy Code) against or company obligation of such CP Conduit Purchaser for
any such insufficiency unless and until such CP Conduit Purchaser satisfies the
provisions of clauses (i) and (ii) above.

rates of interest thereunder, then the Servicer and the Seller each hereby
agrees that comparable fees, charges and increased rates of interest shall be
paid to the Purchasers and Funding Agents hereunder in connection with each
Transfer or otherwise.

     3. Separate Existence. Each of the Seller and USS hereby acknowledges that
        ------------------
the Purchasers and the Funding Agents are entering into the transactions
contemplated by the Agreement and the other Transaction Documents in reliance
upon the Seller's identity as a legal entity separate from USS and its
Affiliates. Therefore, from and after the date hereof, each of the Seller and
USS shall take all steps specifically required by the Agreement or reasonably
requested by any Funding Agent to continue the Seller's identity as a separate
legal entity and to make it apparent to third persons that the Seller is an
entity with assets and liabilities distinct from those of USS and any other
Person, and is not a division of USS, its Affiliates or any other Person.
Without limiting the generality of the foregoing and in addition to and
consistent with the other covenants set forth herein, each of the Seller and USS
shall take such actions as shall be required in order that:

     (a) The Seller will be a limited purpose limited liability company whose
primary activities are restricted in its certificate of incorporation to: (i)
purchasing or otherwise acquiring from the Originators, owning, holding,
granting security interests or selling interests in Pool Assets, (ii) entering
into agreements for the selling and servicing of the Receivables Pool, and (iii)
conducting such other activities as it deems necessary or appropriate to carry
out its primary activities;

     (b) The Seller shall not engage in any business or activity, or incur any
indebtedness or liability, other than as expressly permitted by the Transaction
Documents;

                                     IV-10
<PAGE>

     (c) Not less than one member of the Seller's Board of Directors (the
"Independent Director") shall be an individual who is not a direct, indirect or
 --------------------
beneficial stockholder, officer, director, employee, affiliate, associate or
supplier of USS or any of its Affiliates. The certificate of incorporation of
the Seller shall provide that: (i) the Seller's Board of Directors shall not
approve, or take any other action to cause the filing of, a voluntary bankruptcy
petition with respect to the Seller unless the Independent Director shall
approve the taking of such action in writing before the taking of such action,
and (ii) such provision cannot be amended without the prior written consent of
the Independent Director;

     (d) The Independent Director shall not at any time serve as a trustee in
bankruptcy for the Seller, USS or any Affiliate thereof;

     (e) Any employee, consultant or agent of the Seller will be compensated
from the Seller's funds for services provided to the Seller. The Seller will not
engage any agents other than its attorneys, auditors and other professionals,
and a servicer and any other agent contemplated by the Transaction Documents for
the Receivables Pool, which servicer will be fully compensated for its services
by payment of the Servicing Fee, and a manager, which manager will be fully
compensated from the Seller's funds;

     (f) The Seller will contract with the Servicer to perform for the Seller
all operations required on a daily basis to service the Receivables Pool. The
Seller will pay the Servicer the Servicing Fee pursuant to the Agreement. The
Seller will not incur any material indirect or overhead expenses for items
shared with USS (or any other Affiliate thereof) that are not reflected in the
Servicing Fee. To the extent, if any, that the Seller (or any Affiliate thereof)
shares items of expenses not reflected in the Servicing Fee or the manager's
fee, such as legal, auditing and other professional services, such expenses will
be allocated to the extent practical on the basis of actual use or the value of
services rendered, and otherwise on a basis reasonably related to the actual use
or the value of services rendered; it being understood that USS shall pay all
expenses relating to the preparation, negotiation, execution and delivery of the
Transaction Documents, including legal, agency and other fees;

     (g) The Seller's operating expenses will not be paid by USS or any other
Affiliate thereof;

                                      IV-11
<PAGE>

     (h) All of the Seller's business correspondence and other communications
shall be conducted in the Seller's own name and on its own separate stationery;

     (i) The Seller's books and records will be maintained separately from those
of USS and any other Affiliate thereof;

     (j) All financial statements of USS or any Affiliate thereof that are
consolidated to include Seller will contain detailed notes clearly stating that:
(i) a special purpose corporation exists as a Subsidiary of USS, and (ii) the
Originators have sold receivables and other related assets to such special
purpose Subsidiary that, in turn, has sold undivided interests therein to
certain financial institutions and other entities;

     (k) The Seller's assets will be maintained in a manner that facilitates
their identification and segregation from those of USS or any Affiliate thereof;

     (l) The Seller will observe all company formalities in its dealings with
USS or any Affiliate thereof, and funds or other assets of the Seller will not
be commingled with those of USS or any Affiliate thereof except as permitted by
the Agreement in connection with servicing the Pool Receivables. The Seller
shall not maintain joint bank accounts or other depository accounts to which USS
or any Affiliate thereof (other than USS in its capacity as initial Servicer)
has independent access. The Seller is not named, and has not entered into any
agreement to be named, directly or indirectly, as a direct or contingent
beneficiary or loss payee on any insurance policy with respect to any loss
relating to the property of USS or any Subsidiary or other Affiliate of USS. The
Seller will pay to the appropriate Affiliate the marginal increase or, in the
absence of such increase, the market amount of its portion of the premium
payable with respect to any insurance policy that covers the Seller and such
Affiliate;

     (m) The Seller will maintain arm's-length relationships with USS (and any
Affiliate thereof). Any Person that renders or otherwise furnishes services to
the Seller will be compensated by the Seller at market rates for such services
it renders or otherwise furnishes to the Seller. Neither the Seller nor USS will
be or will hold itself out to be responsible for the debts of the other or the
decisions or actions respecting the daily business and affairs of the other. The
Seller and USS will promptly correct any known misrepresentation with respect to
the foregoing, and they will not operate or purport to operate as an integrated
single

economic unit with respect to each other or in their dealing with any other
entity; and

     (n) USS shall not pay the salaries of Seller's employees, if any.
