     might reasonably injure the Company or its business interests or
     reputation.

     3. ADMINISTRATION OF THE PLAN. The Plan shall be administered by the
Committee. Subject to the provisions of the Plan, the Committee shall have
authority to adopt rules and regulations for carrying out the Plan, determine
the Eligible Employees, determine the exercise price and term of each Stock
Option, determine the vesting period and vesting conditions for Stock Options,
determine the series or class of Common Stock to be subject to the Stock Option,
determine the Fair Market Value of Common Stock, and interpret, construe, and
implement the provisions of the Plan. Decisions of the Committee (including
decisions regarding the interpretation and application of the Plan) shall be
binding on the Company and on all Participants and other interested parties. The
Committee shall hold its meetings at such times and places as it deems
advisable. A majority of the Committee shall constitute a quorum for a meeting.
All determinations of the Committee shall be made by a majority of its members
attending the meeting. Furthermore, any decision or determination reduced to
writing and signed by all of the members of the Committee shall be as effective
as if it had been made by a majority vote at a meeting properly called and held.

     4. ELIGIBLE EMPLOYEES. The individuals who shall be eligible to participate
in the Plan shall be such key executive officers (including executive officers
who may be members of the Board of Directors) of the Company, or of any
subsidiary of the Company, as the Committee shall determine from time to time.

     5. SHARES OF COMMON STOCK SUBJECT TO THE PLAN; MAXIMUM GRANTS. The number
of shares of Common Stock available for Stock Options shall equal 5,000,000. The
shares of Common Stock available under the Plan may consist of shares of any
series of Common Stock provided that the rights of such shares to dividends, to
liquidation proceeds and to share in the appreciation in the value of the
Company shall be not less than the rights of any other series of Common Stock.
If any Stock Option shall expire or terminate for any reason without being
exercised, shares of Common Stock subject to such Stock Option shall again be
available for grant in connection with grants of subsequent Stock Options. The
maximum number of shares of Common Stock that may be granted under Stock Options
to any single Eligible Employee in any 12-month period shall be 750,000.

     6. STOCK OPTION TERMS.

     (a) Exercise Price. The exercise price per share of Common Stock under each
Stock Option shall be determined by the Committee; provided, however, that such
exercise price shall not be less than 100% of the Fair Market Value per share of
such Common Stock on the date of grant, as determined by the Committee.

     (b) Term. The Committee shall fix the term of each Stock Option, which
shall be not more than ten years from the date of grant. In the event no term is
fixed, such term shall be ten years from the date of grant.

                                       A-2

<PAGE>

     (c) Exercise; Transferability. The Committee shall determine the time or
times at which a Stock Option may be exercised in whole or in part; provided,
however, that other than as provided in Section 10, in no event shall a Stock
Option be exercisable before the expiration of six months from the date of its
grant or after ten years from the date of its grant. Stock Options shall not be
transferable by the Participant otherwise than by will, under the laws of
descent and distribution, or pursuant to a qualified domestic relations order
(as defined by the Code) and shall be exercisable only by him or by his duly
appointed personal representative.

     (d) Nonqualified Stock Options. Stock Options shall be "nonqualified" in
that they shall not be designated by the Committee as intended to be qualified
as "incentive" stock options under Section 422 of the Code.

     (e) Method of Exercise. Stock Options shall be exercised by the delivery of
written notice to the Company setting forth the number of shares of Common Stock
with respect to which the Stock Option is to be exercised and, subject to the
subsequent provisions hereof, the address to which the certificates representing
shares of the Common Stock issuable upon the exercise of such Stock Option shall
be mailed. In order to be effective, such written notice shall be accompanied at
the time of its delivery to the Company by payment of the exercise price of such
shares of Common Stock, which payment shall be made in cash or by cashier's
check, certified check, or postal or express money order payable to the order of
the Company in an amount (in United States dollars) equal to the exercise price
of such shares of Common Stock. Such notice shall be delivered in person to the
Secretary of the Company, or shall be sent by registered mail, return receipt
requested, to the Secretary of the Company, in which case, delivery shall be
deemed made on the date such notice is deposited in the mail.

     (f) Withholding. Whenever shares of Common Stock are to be issued or
delivered pursuant to the Plan, the Company shall require the Participant to
remit to the Company an amount sufficient to satisfy federal, state, and local
withholding tax requirements prior to the delivery of any certificate or
certificates for such shares, which payment may be made in the manner set forth
in clause (e) above or in the manner permitted by clause (g) below.

     (g) Alternative Payment for Stock. Alternatively, payment of the exercise
price may be made, in whole or in part, by delivery of shares of Common Stock
already owned by the Participant. Unless otherwise permitted by the Committee,
payment of the exercise price with shares of Common Stock shall be made only
with shares owned by the Participant for at least six (6) months. If payment is
made in whole or in part in shares of Common Stock owned by the Participant,
then the Participant shall deliver to the Company, in payment of the option
price of the shares of Common Stock with respect to which such Stock Option is
exercised, (i) certificates registered in the name of such Participant
representing a number of shares of Common Stock legally and beneficially owned
by such Participant, free of all liens, claims and encumbrances of every kind
and having a Fair Market Value as of the date of delivery of such notice that is
not greater than the exercise price of the shares of Common Stock with respect
to which such Stock Option is to be exercised, such certificates to be
accompanied by stock powers duly endorsed in blank by the record holder of the
shares represented by such certificates; and (ii), if the exercise price of the
shares of Common Stock with respect to which such Stock Option is to be
exercised exceeds such Fair Market Value, cash or a cashier's check, certified
check, or postal or express money order payable to the order of the Company in
an amount (in United States dollars) equal to the amount of such excess.

     The Company may extend and maintain, or arrange for the extension and
maintenance of, financing to any Participant to purchase shares pursuant to
exercise of a Stock Option and/or to pay withholding taxes on such terms as may
be approved by the Committee in its sole discretion. In considering the terms
for extension or maintenance of credit by the Company, the Committee shall,
among other factors, consider the cost to the Company of any financing extended
by the Company.

     (h) Terms of Initial Grants. Of the shares available under the Plan, at
least 3,750,000 shares shall be made as initial grants (the "Initial Grants")
following the adoption of the Plan by the Company's stockholders pursuant to
Section 22. The Stock Option Agreements for each Stock Option that is one of the
Initial Grants to a Participant in connection with the adoption of this Plan
shall contain the following provisions, none of which may be modified or revised
except in compliance with Section 17 of this Plan:

                                       A-3

<PAGE>

          (i) a requirement that the Participant shall not receive any
     additional grants of stock options or other equity interests (including,
     without limitation, restricted stock grants, stock appreciation rights and
     phantom stock rights) in the Company, whether pursuant to this Plan or any
     other plan, prior to the second anniversary of the Participant's initial
     grant under this Plan;

          (ii) a provision that vesting of the Stock Options granted shall not
     occur until seven (7) years following the date of such grant, unless such
     vesting is accelerated pursuant to provision (iii) below; and

          (iii) a vesting schedule setting forth certain internal return on
     invested capital ("ROIC") targets for the Company beginning with the fiscal
     year ending December 31, 2002, which targets, if met, will result in some
     or all of the Stock Options granted becoming vested and exercisable.

     (i) No Change in Exercise Price. The exercise price of any Stock Option
granted at any time shall not be decreased or otherwise "repriced", whether
through amendment, cancellation or replacement grants. This requirement shall
not be modified or revised except in compliance with Section 17 of this Plan.

     7. STOCK OPTION AGREEMENT. The Stock Options awarded to an Eligible
Employee shall be evidenced by a separate written agreement (the "Stock Option
Agreement") which shall be subject to the terms and provisions of the Plan, and
which shall be signed by the Participant and by the Chief Executive Officer or a
Vice President of the Company, other than the Participant, in the name of and on
behalf of the Company. The Stock Option Agreement shall contain such provisions
the Committee in its discretion deems advisable. In the event of any
inconsistency or conflict between the terms of the Plan and a Stock Option
Agreement, the terms of the Plan shall govern.

     8. TERMINATION OF EMPLOYMENT, DEATH, DISABILITY AND RETIREMENT.

     (a) Termination of Employment. If a Participant's employment is terminated
for any reason whatsoever other than death, Disability or Retirement, with
respect to any Stock Option granted pursuant to the Plan outstanding at the
time, unless otherwise established by the Committee, no further vesting shall
occur and the Participant shall be entitled to exercise his or her rights with
respect to the portion of the Stock Option vested as of the date of termination
for a period expiring on the earlier of (i) the expiration date set forth in the
Stock Option Agreement or (ii) ninety (90) calendar days after such termination
date and, thereafter, the Stock Option and the Participant's rights thereunder
shall be completely terminated; provided, however, that if a Participant is
Terminated for Cause, such Participant's right to exercise the vested portion of
his or her Stock Option shall terminate as of 12:01 a.m. on the date of
termination of employment.

     (b) Retirement. Unless otherwise approved by the Committee, upon the
Retirement of a Participant:

          (i) any nonvested portion of any outstanding Stock Option shall
     immediately terminate and no further vesting shall occur; and

          (ii) any vested Stock Option shall expire on the earlier of (A) the
     expiration date set forth in the Stock Option Agreement with respect to
     such Stock Option; or (B) the first anniversary of the date of Retirement.

     (c) Death or Disability. Upon termination of employment as a result of
death or Disability:

          (i) 50% of any nonvested portion of any outstanding Stock Option shall
     immediately and fully vest notwithstanding the original vesting schedule;
     and

          (ii) any vested Stock Option, including those vested pursuant to
     Section (c)(i), shall expire upon the earlier of (A) the expiration date
     set forth in the Stock Option Agreement with respect to such Stock Option
     or (B) the first anniversary of such termination of employment as a result
     of death or Disability.

                                       A-4

<PAGE>

     9. REQUIREMENTS OF LAW. The Company shall not be required to sell or issue
any shares of Common Stock under any Stock Option if the issuance of such shares
shall constitute a violation by the Participant or the Company of any provision
of any law, statute, or regulation of any governmental authority whether it be
Federal or State. Specifically, in connection with the Securities Act, upon
exercise of any Stock Option, unless a registration statement under the
Securities Act is in effect with respect to the shares of Common Stock covered
by such Stock Option, the Company shall not be required to issue such shares
unless the Committee has received evidence satisfactory to it to the effect that
the holder of such Stock Option is acquiring such shares of Common Stock for
investment and not with a view to the distribution thereof, and that such shares
of Common Stock may otherwise be issued without registration under the
Securities Act or State securities laws. Any determination in this connection by
the Committee shall be final, binding and conclusive. The Company may, but shall
in no event be obligated to, register any securities covered hereby pursuant to
the Securities Act. The Company shall not be obligated to take any affirmative
action in order to cause the exercise of a Stock Option, or the issuance of
shares pursuant thereto, to comply with any law or regulation of any
governmental authority.

     10. CHANGE IN STOCK AND ADJUSTMENTS; CHANGE OF CONTROL.

     (a) The existence of outstanding Stock Options shall not affect in any way
the right or power of the Company or its stockholders to make or authorize any
or all adjustments, recapitalizations, reorganizations or other changes in the
Company's capital structure or its business, or any merger or consolidation of
the Company, or any issue of bonds, debentures, preferred or prior preference
stock ahead of, or affecting, the Common Stock or the rights thereof, or the
dissolution or liquidation of the Company, or any sale or transfer of all or any
part of its assets or business, or any other corporate act or proceeding,
whether of a similar character or otherwise.

     (b) If the Company shall effect a subdivision or consolidation of shares or
other capital readjustment, the payment of a stock dividend, or other increase
or reduction of the number of shares of Common Stock outstanding, without
receiving compensation therefor in money, services or property, then (a) the
number, class, and per share price of shares of Common Stock subject to
outstanding Stock Options hereunder shall be appropriately adjusted in such a
manner as to entitle a Participant to receive upon exercise of a Stock Option,
for the same aggregate cash consideration, the same total number and class of
shares as he would have received had he exercised his Stock Option in full
immediately prior to the event requiring the adjustment; and (b) the number and
class of shares then reserved for issuance under the Plan shall be adjusted by
substituting for the total number and class of shares of Common Stock then
reserved that number and class of shares of Common Stock that would have been
received by the owner of an equal number of outstanding shares of each class of
Common Stock as the result of the event requiring the adjustment.

     (c) After a merger of one or more corporations into the Company or after a
consolidation of the Company and one or more corporations in which the Company
is the surviving corporation, each holder of an outstanding Stock Option, upon
exercise of such Stock Option, shall be entitled to receive (at no additional
cost but subject to any required action by stockholders) in lieu of the number
and class of shares of Common Stock with respect to which such Stock Option is
exercisable, the number and class of shares of stock (or other securities or
consideration) to which such holder would have been entitled pursuant to the
terms of the agreement of merger or consolidation if, immediately prior to such
merger or consolidation, such holder had been the holder of record of the same
number and class of shares of Common Stock which he would have otherwise
received upon exercise of such Stock Option.

     (d) If the Company is merged into or consolidated with another corporation
under circumstances where the Company is not the surviving corporation, or if
the Company is liquidated, or sells or otherwise disposes of substantially all
its assets to another corporation while unexercised Stock Options remain
outstanding under the Plan, (i) subject to the provisions of clause (iii) below,
after the effective date of such merger, consolidation, liquidation, or sale, as
the case may be, each holder of an outstanding Stock Option shall be entitled,
upon exercise of such Stock Option, to receive at no additional cost, in lieu of
shares of Common Stock, shares of such stock (or other securities or
consideration) as the holders of shares of Common Stock received pursuant to the
terms of the merger, consolidation, liquidation, or sale; (ii) unless otherwise
provided in the Participant's Stock Option Agreement, any limitations set forth
in or imposed pursuant to this Plan shall automatically lapse so that all Stock
Options, from and after a thirty (30) day period preceding the effective date of
such merger, consolidation, liquidation or sale, as the case may be, shall be
exercisable in full; and (iii) all outstanding Stock Options may be canceled by
the Board as of the effective date of any such merger, consolidation,
liquidation or sale provided that (a) notice of such cancellation shall be given
to each holder of a Stock Option, and (b)

                                       A-5

<PAGE>

unless otherwise provided in the Participant's Stock Option Agreement, each
holder of a Stock Option shall have the right to exercise such Stock Option in
full (without regard to any limitations set forth in or imposed pursuant to
Section 8 hereof) during a thirty (30) day period preceding the effective date
of such merger, consolidation, liquidation, or sale. In the event the
acceleration of vesting provided by clause (ii) or (iii) above would result in
imposition of the excise tax imposed by Section 4999 of the Code, a Participant
may elect to waive such acceleration with respect to such number of shares
subject to unvested Stock Options as the Participant shall designate, and the
Participant shall be entitled to designate from among his unvested Stock Options
those Stock Options which shall not be subject to accelerated vesting.

     (e) Except as expressly provided herein, the issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, for cash, property, labor, or services, either upon direct sale,
exercise of rights or warrants to subscribe therefor, or conversion of shares or
obligations of the Company convertible into such shares or other securities,
shall not affect, and no adjustment by reason thereof shall be made with respect
to, the number, class or price of shares of Common Stock then subject to
outstanding Stock Options.

     (f) Upon a Change of Control, any limitations set forth in or imposed
pursuant to this Plan shall automatically lapse so all Stock Options shall be
exercisable in full. For purposes of this Plan, a "Change of Control" is defined
(i) as the transfer of beneficial ownership of a majority of the outstanding
shares of US Oncology stock to any person or entity (including a "group" as such
term is used in Section 13(d)(3) of the Securities Exchange Act of 1934), except
that if beneficial ownership would be deemed to occur merely upon the execution
of voting agreements to support a merger, consolidation or other transaction to
be consummated in the future, then the Board of Directors may in its sole
discretion determine that the date of such Change of Control shall instead be
the date of such consummation, (ii) the stockholders of the Company prior to any
merger, consolidation or other transaction do not continue to own at least fifty
percent (50%) of the surviving entity following such merger, consolidation or
other transaction; (iii) the Company sells, leases or exchanges all or
substantially all if its assets to any other person or entity (other than a
direct or indirect wholly owned subsidiary of the Company); (iv) the Company is
materially or completely liquidated; or (v) during any consecutive two-year
period, individuals who constituted the Board of Directors of the Company
(together with any new directors whose election by the Board of Directors or
whose nomination for election by the stockholders of the Company was approved by
a vote of at least three quarters of the directors still in office who were
either directors at the beginning of such period or whose election or nomination
for election was previously so approved) cease for any reason to constitute a
majority of the Board of Directors then in office. Notwithstanding anything
contained herein to the contrary, a "Change of Control" shall not be deemed to
have occurred in the event of a tender offer, leveraged buyout, leveraged
recapitalization or similar transaction in which the Company's then Chief
Executive Officer participates or has any agreement or arrangement to
participate directly or indirectly as an investor or participant (e.g., through
receipt of equity, additional stock options or entering into a new employment
agreement) in such transaction.

     11. NO RIGHTS AS STOCKHOLDER. A holder of a Stock Option shall have no
rights as a stockholder with respect to any shares of Common Stock until the
issuance of a stock certificate for such shares. Except as otherwise provided in
Section 10, no adjustment shall be made for dividends (ordinary or
extraordinary, whether in cash, securities, or other property) or distributions
or other rights for which the record date is prior to the date such stock
certificate is issued.

     12. NO EFFECT ON EMPLOYMENT RELATIONSHIP. Participation in the Plan shall
not confer upon any employee any right to continue in the employ of the Company
or interfere in any way with the right of the Company to terminate any
employee's employment at any time.

     13. NO FUND ESTABLISHED. It is not intended that awards under this Plan be
set aside in a trust which would qualify as an employee's trust within the
meaning of sections 401 or 402 of the Internal Revenue Code of 1986, as amended,
or in any other type of trust, fund, or separate account. The rights of any
Participant and any person claiming under such Participant shall not rise above
or exceed those of an unsecured creditor of the Company.

     14. NO ASSIGNMENT OR ALIENATION OF BENEFITS. Except as contemplated by
Section 6(c), no right or benefit under this Plan shall be subject to
anticipation, alienation, sale, assignment, pledge, encumbrance, or charge, and
any attempt to anticipate, alienate, sell, assign, pledge, encumber, or charge
the same shall be void. No right or benefit hereunder shall in any manner be
liable for or subject to any debts, contracts, liabilities, or torts of the
person entitled to such benefits.

                                       A-6

<PAGE>

     15. SUBSTITUTION OPTION. Stock Options may be granted under this Plan from
time to time in substitution for stock options held by employees (or nonemployee
directors) of another corporation who are about to become employees (or
nonemployee directors) of the Company as the result of a merger or consolidation
with the Company, or the acquisition by the Company of the assets of the other
corporation, or the acquisition by the Company of stock of the other corporation
as the result of which it becomes a subsidiary of the Company. The terms and
conditions of the substitute Stock Options so granted may vary from the terms
and conditions set forth in this Plan to such extent as the Board at the time of
grant may deem appropriate to conform, in whole or in part, to the provisions of
the stock options for which such substitute Stock Options are granted.

     16. GENDER, TENSE AND HEADINGS. Whenever the context requires such, words
of the masculine gender used herein shall include the feminine and neuter, and
words used in the singular shall include the plural. Section headings as used
herein are inserted solely for convenience and reference and constitute no part
of the construction of this Plan.

     17. AMENDMENT AND TERMINATION. The Board may modify, revise or terminate
the Plan at any time and from time to time; provided, however, that without the
further approval of the holders of at least a majority of the shares of Common
Stock that cast votes (in person or by proxy) on the proposal at a duly called
meeting, the Board may not (i) change the aggregate number of shares which may
be issued under Stock Options pursuant to the provisions of the Plan; (ii)
reduce the option price at which Stock Options may be granted to an amount less
than 100% of the Fair Market Value per share at the time the Stock Option is
granted, or otherwise materially increase the benefits accruing to Participants
under the Plan; (iii) change the class of persons eligible to receive Stock
Options; (iv) otherwise cause the Plan to not comply with the rules and
regulations promulgated under Section 16(b) of the Exchange Act or Section
162(m) of the Code, if applicable; or (v) change any of the terms set forth in
Sections 6(h) and 6(i), whether set forth in this Plan or in a Stock Option
Agreement. No amendment or termination may adversely affect any vested right of
a Participant without the written consent of such Participant.

     18. NO GUARANTEE OF TAX CONSEQUENCES. Neither the Company nor the Committee
makes any commitment or guarantee that any federal, state or local tax treatment
will apply or be available to any person participating or eligible to
participate hereunder.

     19. SEVERABILITY. In the event that any provision of this Plan shall be
held illegal, invalid or unenforceable for any reason, such provision shall be
fully severable, but shall not affect the remaining provisions of the Plan, and
the Plan shall be construed and enforced as if the illegal, invalid, or
unenforceable provision had never been included herein.

                                   THE CREDITS

     Section 2.01.  Facilities. (a) Revolving Credit Facility. During the
Revolving Credit Period, each Revolving Lender severally agrees, on the terms
and conditions set forth in this Agreement, to make Revolving Loans to the
Borrower from time to time in an aggregate amount such that, after giving effect
to such Loans, the Revolving Outstandings of such Lender do not exceed the
amount of its Revolving Commitment. Each Revolving Borrowing shall be in the
aggregate principal amount of $10,000,000 or any larger multiple of $1,000,000
(except that any such Borrowing may be in the aggregate amount of the unused
Revolving Commitments), and shall be made from the several Revolving Lenders
ratably in proportion to their respective Revolving Commitments. Within the
limits specified in this Agreement, the Borrower may borrow under this Section
2.01, prepay Revolving Loans to the extent permitted by Section 2.09 and
reborrow at any time during the Revolving Credit Period pursuant to this Section
2.01.

     (b)  Term Loan Facility. The Term Loans were advanced to the Borrower on
May 17, 1999 pursuant to the Original Credit Agreement, and there is no further
commitment to make Term Loans hereunder. As of the Restatement Date, after
giving effect to the prepayments to be made on the Restatement Date, the
outstanding principal amount of the Term Loan of each Term Lender will be as set
forth on the Term Loan Schedule. Principal amounts of Term Loans repaid or
prepaid pursuant to Section 2.04 or Section 2.09 shall not be reborrowed.

     Section 2.02.  Notice of Borrowing. The Borrower shall give the
Administrative Agent notice (a "Notice of Borrowing") not later than 11:30 A.M.
(New York City time) (i) on the date of each Base Rate Borrowing and (ii) on the
third Euro-Dollar Business Day before each Euro-Dollar Borrowing, specifying:

          (a)       the date of such Borrowing, which shall be a Domestic
     Business Day in the case of a Base Rate Borrowing or a Euro-Dollar Business
     Day in the case of a Euro-Dollar Borrowing;

          (b)       the aggregate amount of such Borrowing;

          (c)       the initial Type of Loans comprising such Borrowing; and

          (d)       in the case of a Euro-Dollar Borrowing, the duration of the
     initial Interest Period applicable thereto, subject to the provisions of
     the definition of Interest Period.

     Section 2.03.  Notice to Lenders; Funding of Loans. (a) Promptly after
receiving a Notice of Borrowing, the Administrative Agent shall notify each
Lender of the contents thereof and of such Lender's share of such Borrowing.

<PAGE>

     (b)  Not later than 1:00 P.M. (New York City time) on the date of each
Borrowing, each Lender participating therein shall make available its share of
such Borrowing, in Federal or other funds immediately available in New York
City, to the Administrative Agent at its address specified in or pursuant to.
Unless the Administrative Agent determines that any applicable condition
specified in Article 3 has not been satisfied, the Administrative Agent will
make the funds so received from the Lenders available to the Borrower at the
Administrative Agent's aforesaid address.

     (c)  Unless the Administrative Agent shall have received notice from a
Lender before the date of any Borrowing that such Lender will not make available
to the Administrative Agent such Lender's share of such Borrowing, the
Administrative Agent may assume that such Lender has made such share available
to the Administrative Agent on the date of such Borrowing in accordance with
Section 2.03(b) and the Administrative Agent may, in reliance upon such
assumption, make available to the Borrower on such date a corresponding amount.
If and to the extent that such Lender shall not have so made such share
available to the Administrative Agent, such Lender and the Borrower severally
agree to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrower until the date such amount is
repaid to the Administrative Agent, at (i) if such amount is repaid by the
Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the
interest rate applicable to such Borrowing pursuant to Section 2.05 and (ii) if
such amount is repaid by such Lender, the Federal Funds Rate. If such Lender
shall repay to the Administrative Agent such corresponding amount, the Borrower
shall not be required to repay such amount and the amount so repaid by such
Lender shall constitute such Lender's Loan included in such Borrowing for
purposes of this Agreement.

     Section 2.04.  Maturity of Loans; Mandatory Prepayments. (a) Maturity Date.
Each Loan of each Class shall mature, and the outstanding principal amount
thereof shall be due and payable (together with interest accrued thereon), on

the Restatement Date and on or prior to the fourth Quarterly Payment Date prior
to the Maturity Date of the Term Loans the Borrower shall repay, and there shall
become due and payable, an aggregate principal amount of the Term Loans equal to
$1,085,000. On each Quarterly Payment Date occurring thereafter, the Borrower
shall repay, and there shall become due and payable, an aggregate principal
amount of the Term Loans equal to 25% of the aggregate principal amount of the
Term Loans outstanding on the fourth Quarterly Payment Date prior to the
Maturity Date of the Term Loans (immediately after giving effect to the
repayment of the Term Loans made by the Borrower on such Quarterly Payment Date
pursuant to the preceding sentence) or, if less, the aggregate

                                       35

<PAGE>

principal amount of the Term Loans then outstanding (as each such amount may be
reduced pursuant to Section 2.04 and Section 2.09).

to the Mandatory Prepayment Release Date, the Borrower shall, subject to
subsections (e) and (f) of this Section, prepay Term Loans as follows:

          (i)       Upon the receipt by the Borrower or any of its Subsidiaries
     of Net Cash Proceeds in respect of any Reduction Event, the Borrower shall
     prepay the Term Loans in an amount equal to such Net Cash Proceeds;
     provided that if the Net Cash Proceeds in respect of any Reduction Event
     are less than $10,000,000, no such prepayment shall be required until the
     amount of such Net Cash Proceeds, together with the amount of all other Net
     Cash Proceeds in respect of which no prepayment under this subsection
     (c)(i) shall have theretofore been made, are equal to at least $10,000,000.
     The Borrower shall give the Administrative Agent at least three Euro-Dollar
     Business Days' notice of each prepayment required to be made pursuant to
     this subsection (c)(i).

          (ii)      On the 100th day following the last day of each Fiscal Year
     ending during the Restricted Period, the Borrower shall prepay the Term
     Loans in an amount equal to the Excess Cash Flow Prepayment Amount for such
     Fiscal Year.

     (d)  Application of Prepayments and Repayments. (i) Each prepayment of the
Term Loans shall be applied ratably to the respective Term Loans of all Term
Loan Lenders, subject to subsection (e) of this Section.

          (ii)      The amount of any prepayments of Term Loans pursuant to
     subsection (c) of this Section shall be applied to reduce the amount of the
     subsequent scheduled prepayments of the Term Loans required pursuant to
     subsection (b), at the Borrower's option, either pro rata to all remaining
     scheduled prepayments or pro rata to the final four scheduled principal
     payments of the Term Loans.

          (iii)     Each payment of principal of the Term Loans shall be made
     together with interest accrued and unpaid on the amount repaid to the date
     of payment.

          (iv)      Each payment of the Term Loans shall be applied to such
     Group or Groups of Term Loans as the Borrower may designate (or, failing
     such designation, as determined by the Administrative Agent).

     (e)  Option of Term Loan Lenders Not to Accept Mandatory Prepayments. (i)
At least five Euro-Dollar Business Days prior to any date (an "Unscheduled
Prepayment Date") on which any prepayment of the Term Loans

                                       36

<PAGE>

(a "Term Loan Unscheduled Prepayment") would, but for the provisions of this
subsection (e), otherwise be required pursuant to subsection (c) of this
Section, the Borrower shall deliver a notice conforming to the requirements of
subsection (d)(ii) (a "Term Loan Prepayment Notice") to the Administrative
Agent. Upon receipt of any Term Loan Prepayment Notice, the Administrative Agent
shall promptly notify each Term Loan Lender of the contents thereof, and such
Term Loan Unscheduled Prepayment shall not occur on such Unscheduled Payment
Date but shall instead be deferred as hereinafter provided in this subsection
(d).

     refer to this Section and shall (w) set forth the amount (or if
     unascertainable at such time, the maximum and minimum amounts) of the Term
     Loan Unscheduled Prepayment and the prepayment that the applicable Term
     Loan Lender will be entitled to receive if it accepts prepayment of its
     Term Loans in accordance with this subsection, (x) contain an offer to
     prepay on a specified date (each such date, a "Deferred Term Loan
     Unscheduled Prepayment Date"), which shall be the tenth Euro-Dollar
     Business Day after the date of such Term Loan Prepayment Notice, the Term
     Loans of such Term Loan Lender by an aggregate principal amount equal to
     such Term Loan Lender's ratable share of such Term Loan Unscheduled
     Prepayment (determined by reference to the outstanding principal amount of
     such Lender's Term Loan as a proportion of the aggregate outstanding
     principal amount of the Term Loans of all of the Term Loan Lenders), (y)
     request such Term Loan Lender to notify the Borrower and the Administrative
     Agent in writing, no later than the third Euro-Dollar Business Day prior to
     the Deferred Term Loan Unscheduled Prepayment Date, of such Term Loan
     Lender's acceptance or rejection (in each case, in whole and not in part)
     of such offer of prepayment and (z) inform such Term Loan Lender that the
     failure by such Term Loan Lender to reject such offer in writing on or
     before the third Euro-Dollar Business Day prior to such Deferred Term Loan
     Unscheduled Prepayment Date shall be deemed an acceptance of such
     prepayment offer. Notwithstanding the foregoing, if the Borrower has
     delivered notice pursuant to Section 2.09 to prepay in full the Term Loans
     in connection with the occurrence of a Reduction Event, the Borrower shall
     not be required to deliver a Term Loan Prepayment Notice in connection with
     such Reduction Event.

          (iii)     Subject to subsection (f) of this Section, on each Deferred
     Term Loan Unscheduled Prepayment Date, the Borrower shall pay to the
     Administrative Agent for application to the prepayment of the outstanding
     Term Loans of each of the Term Lenders that shall have accepted (or been
     deemed to have accepted) prepayment (each, an "Accepting Term Lender"), an
     amount equal to the aggregate ratable shares (determined as specified in
     paragraph (i) above) of the Accepting Term Lenders of the amount that would
     have been payable by the Borrower pursuant to

                                       37

<PAGE>

     subsection (b) of this Section on the related Unscheduled Prepayment Date
     but for the provisions of this subsection (e).

     (f)  Deferred Payment. If subsections (c) and (e) of this Section would
otherwise require prepayment of Euro-Dollar Loans or portions thereof prior to
the last day of the then current Interest Period therefor, each such prepayment
may, if the Borrower so elects and unless the Administrative Agent otherwise
notifies the Borrower upon the instructions of the Required Lenders, be deferred
to such last day of the related Interest Period. The Borrower shall use
reasonable efforts to minimize any deferrals of payments pursuant to this
subsection.

     (g)  Remaining Net Cash Proceeds. To the extent that the aggregate amount
required to be paid to the Accepting Term Lenders with respect to any Prepayment
Event is less than the Net Cash Proceeds of such Reduction Event, the Borrower
or relevant Subsidiary may, subject to the other terms of this Agreement, use
any such remaining Net Cash Proceeds for any purpose not prohibited by this
Agreement.

     Section 2.05.  Interest Rates. (a) Each Base Rate Loan shall bear interest
on the outstanding principal amount thereof, for each day from the date such
Loan is made until it becomes due, at a rate per annum equal to the sum of the
Applicable Margin and the Base Rate for such day. Such interest shall be payable
quarterly in arrears on each Quarterly Payment Date. Any overdue principal of or
interest on any Base Rate Loan shall bear interest, payable on demand, for each
day until paid at a rate per annum equal to the sum of the Applicable Margin
plus the Base Rate for such day.

     (b)  Each Euro-Dollar Loan shall bear interest on the outstanding principal
amount thereof, for each day during each Interest Period applicable thereto, at
a rate per annum equal to the sum of the Applicable Margin for such day plus the
London Interbank Offered Rate applicable to such Interest Period. Such interest
shall be payable for each Interest Period on the last day thereof and, if such
Interest Period is longer than three months, at intervals of three months after
the first day thereof.

     The "London Interbank Offered Rate" applicable to any Interest Period means
the rate appearing on Page 3750 of the Telerate screen, at approximately 11:00
A.M. (London time) two Euro-Dollar Business Days before the first day of such
Interest Period, as the rate for dollar deposits with a maturity comparable to
such Interest Period. In the event that such rate is not available at such time
for any reason, then the "London Interbank Offered Rate" applicable to such
Interest Period shall be the average (rounded upward, if necessary, to the next
higher 1/100 of 1%) of the respective rates per annum at which deposits in
dollars are offered to each of the Reference Lenders in the London interbank
market at approximately 11:00 A.M. (London time) two Euro-Dollar Business Days
before the first day of such Interest Period in an amount approximately equal to
the

                                       38

<PAGE>

principal amount of the Euro-Dollar Loan of such Reference Lender to which such
Interest Period is to apply and for a period of time comparable to such Interest
Period. If any Reference Lender does not furnish a timely quotation, the
Administrative Agent shall determine the relevant interest rate on the basis of
the quotation or quotations furnished by the remaining Reference Lender or
Lenders or, if none of such quotations is available on a timely basis, the
provisions of Section 8.01 shall apply.

     (c)  Any overdue principal of or interest on any Euro-Dollar Loan shall
bear interest, payable on demand, for each day until paid at a rate per annum
equal to the higher of (i) the sum of the Applicable Margin for such day plus
the London Interbank Offered Rate applicable to such Loan on the day before such
payment was due and (ii) the sum of the Applicable Margin for such day plus a
rate per annum equal to the quotient obtained (rounded upward, if necessary, to
the next higher 1/100 of 1%) by dividing (x) the average (rounded upward, if
necessary, to the next higher 1/16 of 1%) of the respective rates per annum at
which one day (or, if such amount due remains unpaid more than three Euro-Dollar
Business Days, then for such other period of time not longer than three months
as the Administrative Agent may select) deposits in dollars in an amount
approximately equal to such overdue payment due to each of the Reference Lenders
are offered to such Reference Lender in the London interbank market for the
applicable period determined as provided above by (y) 1.00 minus the Euro-Dollar
Reserve Percentage (or, if the circumstances described in clause 8.01(a) or
8.01(b) shall exist, at a rate per annum equal to the rate applicable to overdue
Base Rate Loans of such Class for such day).

     (d)  The Administrative Agent shall determine each interest rate applicable
to the Loans hereunder. The Administrative Agent shall promptly notify the
Borrower and the Lenders of each rate of interest so determined, and its
determination thereof shall be conclusive in the absence of manifest error.

     (e)  Each Reference Lender agrees to use its best efforts to furnish
quotations to the Administrative Agent if and when contemplated by this Section.

     Section 2.06.  Method of Electing Interest Rates. (a) The Loans included in
each Borrowing shall bear interest initially at the type of rate specified by
the Borrower in the applicable Notice of Borrowing. Thereafter, the Borrower may
from time to time elect to change or continue the type of interest rate borne by
each Group of Term Loans or Revolving Loans (subject to subsection (d) and the
provisions of Article 8), as follows:

          (i)       if such Loans are Base Rate Loans, the Borrower may elect to
     convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day;
     and

                                       39

<PAGE>

          (ii)      if such Loans are Euro-Dollar Loans, the Borrower may elect
     to convert such Loans to Base Rate Loans as of any Domestic Business Day or
     elect to continue such Loans as Euro-Dollar Loans for an additional
     Interest Period, subject to Section 2.11 if any such conversion is
     effective on any day other than the last day of an Interest Period
     applicable to such Loans.

Each such election shall be made by delivering a notice (a "Notice of Interest
Rate Election") to the Administrative Agent not later than 11:30 A.M. (New York
City time) on the third Euro-Dollar Business Day before the conversion or
continuation selected in such notice is to be effective. A Notice of Interest
Rate Election may, if it so specifies, apply to only a portion of the aggregate
principal amount of the relevant Group of Loans; provided that (i) such portion
is allocated ratably among the Loans comprising such Group and (ii) the portion
to which such Notice applies, and the remaining portion to which it does not
apply, are each at least $10,000,000 (unless such portion is comprised of Base
Rate Loans). If no such notice is timely received before the end of an Interest
Period for any Group of Euro-Dollar Loans, the Borrower shall be deemed to have
elected that such Group of Loans be converted to Base Rate Loans at the end of
such Interest Period.

     (b)  Each Notice of Interest Rate Election shall specify:

          (i)       the Group of Loans (or portion thereof) to which such notice
     applies;

          (ii)      the date on which the conversion or continuation selected in
     such notice is to be effective, which shall comply with the applicable
     clause of subsection (a) above;

          (iii)     if the Loans comprising such Group are to be converted, the
     new Type of Loans and, if the Loans resulting from such conversion are to
     be Euro-Dollar Loans, the duration of the next succeeding Interest Period
     applicable thereto; and

          (iv)      if such Loans are to be continued as Euro-Dollar Loans for
     an additional Interest Period, the duration of such additional Interest
     Period.

     Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of Interest Period.

     (c)  Promptly after receiving a Notice of Interest Rate Election from the
Borrower pursuant to subsection (a) above, the Administrative Agent shall notify
each Lender of the contents thereof and such notice shall not thereafter be
revocable by the Borrower.

                                       40

<PAGE>

     (d)  The Borrower shall not be entitled to elect to convert any Loans to,
or continue any Loans for an additional Interest Period as, Euro-Dollar Loans if
(i) the aggregate principal amount of any Group of Euro-Dollar Loans created or
continued as a result of such election would be less than $10,000,000 or (ii) a
Default shall exist when the Borrower delivers notice of such election to the
Administrative Agent.

     (e)  If any Loan is converted to a different Type of Loan, the Borrower
shall pay, on the date of such conversion, the interest accrued to such date on
the principal amount being converted.

     Section 2.07.  Fees. (a) During the Revolving Credit Period, the Borrower
shall pay to the Administrative Agent for the account of the Revolving Lenders
ratably in proportion to their Revolving Commitments commitment fees at the
Commitment Fee Rate (determined daily in accordance with the Pricing Schedule)
on the daily amount by which the aggregate amount of the Revolving Commitments
exceeds the sum of (i) the aggregate outstanding principal amount of Revolving
Loans and (ii) the aggregate Letter of Credit Liabilities. Such commitment fee
shall accrue from and including the Restatement Date to but excluding the date
of termination of the Revolving Commitments in their entirety.

     (b)  The Borrower shall pay to the Administrative Agent (i) for the account
of the Revolving Lenders ratably a letter of credit fee accruing daily on the
aggregate undrawn amount of all outstanding Letters of Credit at a rate per
annum equal to the Applicable Margin for Revolving Euro-Dollar Loans for such
day and (ii) for the account of each Issuing Bank a letter of credit fronting
fee accruing daily on the aggregate amount then available for drawing under all
Letters of Credit issued by such Issuing Bank at a rate per annum mutually
agreed between the Borrower and such Issuing Bank from time to time.

     (c)  Accrued commitment and letter of credit fees under this Section shall
be payable quarterly in arrears on each Quarterly Payment Date and on the date
of termination of the Revolving Commitments in their entirety.

     Section 2.08.  Termination or Reduction of Commitments. (a) The Borrower
may, upon at least three Domestic Business Days' notice to the Administrative
Agent, (i) terminate the Commitments of any Class at any time, if no Loans of
such Class (and, in the case of the Revolving Commitments, no Letter of Credit
Liabilities and no Swing Loans) are outstanding at such time (after giving
effect to any mandatory or optional prepayments to be made at such time) or (ii)
ratably reduce from time to time by an aggregate amount of $10,000,000 or any
larger multiple of $1,000,000 the aggregate amount of the Commitments of any
Class in excess of the aggregate outstanding principal amount of the Loans of
such Class (and, in the case of the Revolving Commitments, the aggregate
principal amount of the Letter of Credit Liabilities and Swing Loans). Promptly
after receiving a notice of a termination or

                                       41

<PAGE>

reduction of Commitments, the Administrative Agent shall notify each Lender of
each relevant Class of the contents thereof.

     (b)  Unless previously terminated, the Revolving Commitments shall
terminate in their entirety on the Revolving Credit Termination Date.

     (c)  The Swing Loan Commitment shall terminate in its entirety on the
earlier of the Swing Loan Termination Date or the date on which the Revolving
Commitments terminate in their entirety.

     Section 2.09.  Optional Prepayments. (a) Subject in the case of Euro-Dollar
Loans to Section 2.11, the Borrower may (i) upon at least one Domestic Business
Day's notice to the Administrative Agent, prepay any Group of Base Rate Loans of
any Class or (ii) upon at least three Euro-Dollar Business Days' notice to the
Administrative Agent, prepay any Group of Euro-Dollar Loans of any Class, in
each case in whole at any time, or from time to time in part in amounts
aggregating $10,000,000 or any larger multiple of $1,000,000 by paying the
principal amount to be prepaid together with interest accrued thereon to the
date of prepayment; provided that upon any optional prepayment of the Term Loans
on or prior to May 17, 2004, the Borrower shall also pay a prepayment fee equal
to the Applicable Term Loans Prepayment Fee Percentage of the principal amount
of such Term Loans being prepaid.

     (b)  Promptly after receiving a notice of prepayment pursuant to this
Section, the Administrative Agent shall notify each Lender of the contents
thereof and of such Lender's ratable share (if any) of such prepayment, and such
notice shall not thereafter be revocable by the Borrower.

     (c)  The amount of any prepayment of Term Loans pursuant to this Section
shall be applied to either, at the Borrower's option, (i) first, to the next
scheduled payment in respect of such Loans pursuant to Section 2.04(b) to the
extent necessary to reduce such next scheduled payment to zero, and, second, pro
rata to all subsequent scheduled payments in respect of such Loans pursuant to
Section 2.04(b) or (ii) pro rata to the final four scheduled principal payments
of the Term Loans.

     (d)  Notwithstanding the foregoing, if the Borrower includes in its notice
to the Administrative Agent pursuant to Section 2.09(a) of its election to
prepay any Group of Loans (which for purposes of this subsection (d) may include
an election to prepay Term Loans) that the Lenders may reject the prepayment so
proposed by the Borrower, then the provisions of Section 2.04(e), (f) and (g)
shall apply to any such offered prepayment, mutatis mutandis, as though the
offered prepayment were a mandatory prepayment of the Term Loans pursuant to
Section 2.04(c)(i) or (ii); provided, however, to the extent any Lender accepts
a prepayment offered pursuant to this subsection (d), such prepayment shall be
made together with any applicable premium specified in Section 2.09.(a).

                                       42

     Section 2.10.  General Provisions as to Payments. (a) The Borrower shall
make each payment of principal of, and interest on, the Loans, of Letter of
Credit Liabilities or interest thereon or of fees hereunder not later than 1:00
P.M. (New York City time) on the date when due, in Federal or other funds
immediately available in New York City, to the Administrative Agent at its
address specified in or pursuant to Section 9.01. The Administrative Agent will
promptly distribute to each Lender its ratable share of each such payment
received by the Administrative Agent for the account of the Lenders. Whenever
any payment of principal of, or interest on, the Base Rate Loans, of Letter of
Credit Liabilities or interest thereon or of fees hereunder shall be due on a
day which is not a Domestic Business Day, the date for payment thereof shall be
extended to the next succeeding Domestic Business Day. Whenever any payment of
principal of, or interest on, the Euro-Dollar Loans shall be due on a day which
is not a Euro-Dollar Business Day, the date for payment thereof shall be
extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar
Business Day falls in another calendar month, in which case the date for payment
thereof shall be the immediately preceding Euro-Dollar Business Day. If the date
for any payment of principal is extended by operation of law or otherwise,
interest thereon shall be payable for such extended time.

     (b)  Unless the Borrower notifies the Administrative Agent before the date
on which any payment is due to the Lenders hereunder that the Borrower will not
make such payment in full, the Administrative Agent may assume that the Borrower
has made such payment in full to the Administrative Agent on such date and the
Administrative Agent may, in reliance on such assumption, cause to be
distributed to each Lender on such due date an amount equal to the amount then
due such Lender. If and to the extent that the Borrower shall not have so made
such payment, each Lender shall repay to the Administrative Agent forthwith on
demand such amount distributed to such Lender together with interest thereon,
for each day from the date such amount is distributed to such Lender until the
date such Lender repays such amount to the Administrative Agent, at the Federal
Funds Rate.

     Section 2.11.  Funding Losses. If the Borrower makes any payment of
principal with respect to any Fixed Rate Loan or any Euro-Dollar Loan is
converted to a Base Rate Loan (whether such payment or conversion is pursuant to
Article 2, 6 or 8 or otherwise) on any day other than the last day of an
Interest Period applicable thereto, or the last day of an applicable period
fixed pursuant to Section 2.05(c), or if the Borrower fails to borrow, prepay,
convert or continue any Fixed Rate Loan after notice has been given to any
Lender in accordance with Section 2.02(a), 2.06(c), 2.09(b), or 2.17, the
Borrower shall reimburse each Lender requesting such reimbursement within 15
days after demand for any resulting loss or expense incurred by it (or by a
Participant in the related Loan), including (without limitation) any loss
incurred in obtaining, liquidating or employing deposits from third parties, but
excluding loss of margin for the period

                                       43

<PAGE>

after such payment or conversion or failure to borrow, prepay, convert or
continue; provided that such Lender shall have delivered to the Borrower a
certificate setting forth in reasonable detail the calculation of the amount of
such loss or expense, which certificate shall be conclusive in the absence of
manifest error.

     Section 2.12.  Computation of Interest and Fees. Interest based on the
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

     Section 2.13.  Notes. (a) If a Lender so requests in writing, the
Borrower's obligation to repay the Loans of such Lender shall be evidenced by a
single Note payable to the order of such Lender for the account of its
Applicable Lending Office.

     (b)  Each Lender may, by notice to the Borrower and the Administrative
Agent, request that the Borrower's obligation to repay such Lender's Loans of a
particular Type or Class be evidenced by a separate Note. Each such Note shall
be in substantially the form of Exhibit A hereto with appropriate modifications
to reflect the fact that it relates solely to Loans of the relevant Type or
Class. Each reference in this Agreement to the "Note" of such Lender shall be
deemed to refer to and include any or all of such Notes, as the context may
require.

     (c)  Promptly after it receives any Lender's Note pursuant to Article 3,
the Administrative Agent shall forward such Note to such Lender. Each Lender
shall record the date, amount, Class and Type of each Loan made by it and the
date and amount of each payment of principal made by the Borrower with respect
thereto, and may, if such Lender so elects in connection with any transfer or
enforcement of its Note, endorse on the schedule forming a part thereof
appropriate notations to evidence the foregoing information with respect to each
such Loan then outstanding; provided that a Lender's failure to make (or any
error in making) any such recordation or endorsement shall not affect the
Borrower's obligations hereunder or under the Notes. Each Lender is hereby
irrevocably authorized by the Borrower so to endorse its Note and to attach to
and make a part of its Note a continuation of any such schedule as and when
required.

     Section 2.14.  Registry. The Administrative Agent, acting for this purpose
as an agent of the Borrower, shall maintain a register (the "Register") on which
it will record the name and Commitment of each Lender, each Loan made by such
Lender and each repayment of any Loan made by such Lender. With respect to any
Lender, the assignment or other transfer of the Commitments of such Lender and
the rights to the principal of, and interest on, any Loan made and Note issued
pursuant to this Agreement shall not be effective until such assignment or other

                                       44

<PAGE>

transfer is recorded on the Register and otherwise complies with Section
9.06(c). Upon receipt of a properly executed and delivered Assignment and
Assumption Agreement referred to in Section 9.06(c), the Administrative Agent
shall accept such Assignment and Assumption Agreement and record such assignment
or other transfer of all or part of any Commitments, Loans and Notes for a
Lender on the Register. The Register shall be available at the offices where
kept by the Administrative Agent for inspection by the Borrower and any Lender
at any reasonable time upon reasonable prior notice to the Administrative Agent.
Each Lender shall record on its internal records (including computerized
systems) the foregoing information as to its own Commitments and Loans. Failure
to make any such recordation, or any error in such recordation, shall not affect
the obligations of any Obligor under the Loan Documents.

     Section 2.15.  Regulation D Compensation. If and so long as a reserve
requirement of the type described in the definition of "Euro-Dollar Reserve
Percentage" is prescribed by the Board of Governors of the Federal Reserve
System (or any successor), each Lender subject to such requirement may require
the Borrower to pay, contemporaneously with each payment of interest on each of
such Lender's Euro-Dollar Loans, additional interest on such Euro-Dollar Loan at
a rate per annum determined by such Lender up to but not exceeding the excess of
(i) (A) the applicable London Interbank Offered Rate divided by (B) one minus
the Euro-Dollar Reserve Percentage over (ii) the applicable London Interbank
Offered Rate. Any Lender wishing to require payment of such additional interest
(x) shall so notify the Borrower and the Administrative Agent, in which case
such additional interest on the Euro-Dollar Loans of such Lender shall be
payable to such Lender at the place indicated in such notice with respect to
each Interest Period commencing at least three Euro-Dollar Business Days after
such Lender gives such notice and (y) shall notify the Borrower at least five
Euro-Dollar Business Days before each date on which interest is payable on the
Euro-Dollar Loans of the amount then due it under this Section. It is understood
that (x) no additional interest is payable under this Section in respect of
Euro-Dollar Loans not paid when due and (y) amounts claimed by any Lender under
this Section shall be based on an assumed level of reserves maintained by it
which is consistent with such Lender's good faith estimate of the actual level
at which the related reserves are required to be maintained by it over time.

     Section 2.16.  Letters of Credit. (a) Commitment to Issue Letters of
Credit. (i) Subject to the terms and conditions hereof, and so long as no Stop
Issuance Notice is in effect, each Issuing Bank agrees to issue Letters of
Credit from time to time before the Letter of Credit Termination Date upon the
request of the Borrower; provided that, immediately after each Letter of Credit
is issued (i) the aggregate amount of the Revolving Outstandings shall not
exceed the aggregate amount of the Revolving Commitments and (ii) the aggregate
amount of the Letter of Credit Liabilities shall not exceed $150,000,000. Upon
the date of issuance by an Issuing Bank of a Letter of Credit, the Issuing Bank
shall be

                                       45

<PAGE>

deemed, without further action by any party hereto, to have sold to each
Revolving Lender, and each Revolving Lender shall be deemed, without further
action by any party hereto, to have purchased from the Issuing Bank, a
participation in such Letter of Credit and the related Letter of Credit
Liabilities in the proportion its respective Revolving Commitment bears to the
aggregate Revolving Commitments.

          (ii)      On the Restatement Date, without further action by any party
     hereto, each Issuing Bank that has issued an Existing Letter of Credit
     shall be deemed to have granted to each Revolving Lender, and each
     Revolving Lender shall be deemed to have acquired from such Issuing Bank, a
     participation in each Existing Letter of Credit and the related Letter of
     Credit Liabilities in the proportion its respective Revolving Commitment
     bears to the aggregate Revolving Commitments, all on the same terms and
     conditions as if such Existing Letters of Credit had been issued on the
     Restatement Date pursuant to Section 2.16(a)(1). Each Lender party to the
     Original Credit Agreement, including each Departing Lender, agrees that its
     participation in the Existing Letters of Credit acquired pursuant to the
     Original Credit Agreement shall be cancelled on the Restatement Date
     without further action by any party.

     (b)  Method for Issuance; Terms; Extensions. (i) The Borrower shall give
the Issuing Bank notice at least five Domestic Business Days (or such shorter
notice as may be acceptable to the Issuing Bank in its discretion) prior to the
requested issuance of a Letter of Credit specifying the date such Letter of
Credit is to be issued, and describing the terms of such Letter of Credit and
the nature of the transactions to be supported thereby (such notice, including
any such notice given in connection with the extension of a Letter of Credit, a
"Notice of Issuance"). Upon receipt of a Notice of Issuance, the Issuing Bank
shall promptly notify the Administrative Agent, and the Administrative Agent
shall promptly notify each Revolving Lender of the contents thereof and of the
amount of such Lender's participation in such Letter of Credit.

          (ii)      The issuance by the Issuing Bank of each Letter of Credit
     shall, in addition to the conditions precedent set forth in Section 3.02,
     be subject to the conditions precedent that such Letter of Credit shall be
     in such form and contain such terms as shall be reasonably satisfactory to
     the Issuing Bank and that the Borrower shall have executed and delivered
     such other instruments and agreements relating to such Letter of Credit as
     the Issuing Bank shall have reasonably requested. The Borrower shall also
     pay to the Issuing Bank for its own account issuance, drawing, amendment
     and extension charges in the amounts and at the times as agreed between the
     Borrower and the Issuing Bank.

          (iii)     The extension or renewal of any Letter of Credit shall be
     deemed to be an issuance of such Letter of Credit, and if any Letter of

                                       46

<PAGE>

     Credit contains a provision pursuant to which it is deemed to be extended
     unless notice of termination is given by the Issuing Bank, the Issuing Bank
     shall timely give such notice of termination unless it has theretofore
     timely received a Notice of Issuance and the other conditions to issuance
     of a Letter of Credit have also theretofore been met with respect to such
     extension. No Letter of Credit shall have a term of more than one year;
     provided that a Letter of Credit may contain a provision pursuant to which
     it is deemed to be extended on an annual basis unless notice of termination
     is given by the Issuing Bank; provided further that no Letter of Credit
     shall have a term extending or be so extendible beyond the Letter of Credit
     Termination Date.

     (c)  Payments; Reimbursement Obligations. (i) Upon receipt from the
beneficiary of any Letter of Credit of any notice of a drawing under such Letter
of Credit, the Issuing Bank shall notify the Administrative Agent and the
Administrative Agent shall promptly notify the Borrower and each other Revolving
Lender as to the amount to be paid as a result of such demand or drawing and the
payment date. The Borrower shall be irrevocably and unconditionally obligated
forthwith to reimburse the Issuing Bank for any amounts paid by the Issuing Bank
upon any drawing under any Letter of Credit, without presentment, demand,
protest or other formalities of any kind.

          (ii)      All such amounts paid by the Issuing Bank and remaining
     unpaid by the Borrower (a "Reimbursement Obligation") shall, if and to the
     extent that the amount of such Reimbursement Obligation would be permitted
     as a Borrowing pursuant to Section 3.02, and unless the Borrower otherwise
     instructs the Administrative Agent by not less than one Domestic Business
     Day's prior notice, convert automatically to Revolving Base Rate Loans on
     the date such Reimbursement Obligation arises. The Administrative Agent
     shall, on behalf of the Borrower (which hereby irrevocably directs the
     Administrative Agent so to act on its behalf), give notice no later than
     11:30 A.M. (New York City time) on such date requesting each Revolving
     Lender to make, and each Revolving Lender hereby agrees to make, a
     Revolving Base Rate Loan, in an amount equal to such Revolving Lender's
     Revolving Credit Percentage of the Reimbursement Obligation with respect to
     which such notice relates. Each Revolving Lender shall make such Loan
     available to the Administrative Agent at its address specified in or
     pursuant to Section 9.01 in immediately available funds, not later than
     1:00 P.M. (New York City time), on the date specified in such notice. The
     Administrative Agent shall pay the proceeds of such Revolving Loans to the
     Issuing Bank, which shall immediately apply such proceeds to repay the
     Reimbursement Obligation. All amounts not so repaid shall bear interest,
     payable on demand, for each day until paid at a rate per annum equal to the
     rate applicable to Revolving Base Rate Loans for such day.

                                       47

<PAGE>

          (iii)     To the extent the Reimbursement Obligation is not refunded
     by a Revolving Lender pursuant to clause (ii) above, such Revolving Lender
     will pay to the Administrative Agent, for the account of the Issuing Bank,
     immediately upon the Issuing Bank's demand at any time during the period
     commencing after such Reimbursement Obligation arises until reimbursement
     therefor in full by the Borrower, an amount equal to such Revolving
     Lender's ratable share of such Reimbursement Obligation (in proportion to
     its participation therein), together with interest on such amount for each
     day from the date of the Issuing Bank's demand for such payment (or, if
     such demand is made after 1:00 P.M. (New York City time) on such date, from
     the next succeeding Domestic Business Day) to the date of payment by such
     Lender of such amount at a rate of interest per annum equal to the Federal
     Funds Rate for the first three Domestic Business Days after the date of
     such demand and thereafter at a rate per annum equal to the Base Rate for
     each additional day. The Issuing Bank will pay to each Revolving Lender
     ratably all amounts received from the Borrower for application in payment
     of its Reimbursement Obligations in respect of any Letter of Credit, but
     only to the extent such Revolving Lender has made payment to the Issuing
     Bank in respect of such Letter of Credit pursuant hereto; provided that in
     the event such payment received by the Issuing Bank is required to be
     returned, such Revolving Lender will return to the Issuing Bank any portion
     thereof previously distributed to it by the Issuing Bank.

     (d)  Obligations Absolute. The obligations of the Borrower and each
Revolving Lender under subsection (c) above shall be absolute, unconditional and
irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement, under all circumstances whatsoever, including without limitation
the following circumstances:

          (i)       any lack of validity or enforceability of this Agreement or
     any Letter of Credit or any document related hereto or thereto;

          (ii)      any amendment or waiver of or any consent to departure from
     all or any of the provisions of this Agreement or any Letter of Credit or
     any document related hereto or thereto;

          (iii)     the use which may be made of the Letter of Credit by, or any
     acts or omission of, a beneficiary of a Letter of Credit (or any Person for
     whom the beneficiary may be acting);

          (iv)      the existence of any claim, set-off, defense or other rights
     that the Borrower may have at any time against a beneficiary of a Letter of
     Credit (or any Person for whom the beneficiary may be acting), any Lender
     (including the Issuing Bank) or any other Person, whether in

                                       48

<PAGE>

     connection with this Agreement or the Letter of Credit or any document
     related hereto or thereto or any unrelated transaction;

          (v)       any statement or any other document presented under a Letter
     of Credit proving to be forged, fraudulent or invalid in any respect or any
     statement therein being untrue or inaccurate in any respect whatsoever; or

          (vi)      any other act or omission to act or delay of any kind by any
     Lender (including the Issuing Bank), the Administrative Agent or any other
     Person or any other event or circumstance whatsoever that might, but for
     the provisions of this subsection (vi), constitute a legal or equitable
     discharge of or defense to the Borrower's or the Lender's obligations
     hereunder.

     (e)  Indemnification; Expenses. (i) Borrower hereby indemnifies and holds
harmless each Revolving Lender (including each Issuing Bank) and the
Administrative Agent from and against any and all claims, damages, losses,
liabilities, costs or expenses which it may reasonably incur in connection with
a Letter of Credit issued pursuant to this Section 2.16.

          (ii)      None of the Revolving Lenders (including an Issuing Bank)
     nor the Administrative Agent nor any of their officers or directors or
     employees or agents shall be liable or responsible, by reason of or in
     connection with the execution and delivery or transfer of or payment or
     failure to pay under any Letter of Credit, including without limitation any
     of the circumstances enumerated in subsection (d) above; provided that the
     Borrower shall not be required to indemnify any Lender, or the
     Administrative Agent, for any claims, damages, losses, liabilities, costs
     or expenses, to the extent found by a court of competent jurisdiction to
     have been caused by the gross negligence or willful misconduct of such
     Person; and provided further that, notwithstanding Section 2.16(d), the
     Borrower and each Lender shall have a claim for direct (but not
     consequential) damage suffered by it, to the extent found by a court of
     competent jurisdiction to have been caused by (x) the willful misconduct or
     gross negligence of the Issuing Bank in determining whether a request
     presented under any Letter of Credit complied with the terms of such Letter
     of Credit or (y) the Issuing Bank's failure to pay under any Letter of
     Credit after the presentation to it of a request strictly complying with
     the terms and conditions of the Letter of Credit.

          (iii)     Nothing in this subsection (e) is intended to limit the
     obligations of the Borrower under any other provision of this Agreement. To
     the extent the Borrower does not indemnify an Issuing Bank as required by
     this subsection, the Revolving Lenders agree to do so ratably in accordance
     with their Revolving Commitments.

     Section 2.17.  Swing Loans. (a) Swing Loan Commitment. During the Swing
Credit Period, so long as no Stop Issuance Notice is in effect, the Swing Loan
Lender agrees, on the terms and conditions set forth in this Agreement, to make
Swing Loans to the Borrower pursuant to this subsection from time to time in
amounts such that at any time (i) the aggregate principal amount of Swing Loans
outstanding at such time does not exceed the Swing Loan Commitment and (ii) the
aggregate amount of Revolving Outstandings at such time does not exceed the
aggregate amount of the Revolving Commitments at such time. Each Borrowing under
this Section shall be in a principal amount of $1,000,000 or any larger multiple
of $500,000 (except that any such Borrowing may be in the amount of the Swing
Loan Commitment available in accordance with the immediately preceding
sentence). Within the foregoing limits, the Borrower may borrow under this
subsection, prepay Swing Loans and reborrow at any time during the Swing Credit
Period under this subsection.

     (b)  Swing Loan Borrowing Procedure. The Borrower shall give the Swing Loan
Lender notice (a "Notice of Swing Loan Borrowing"), not later than 12:00 Noon
(New York City time) on the date of each Swing Loan Borrowing, specifying the
amount and the date of such Borrowing, which shall be a Euro-Dollar Business
Day. Not later than 2:00 P.M. (New York City time) on the date of each Swing
Loan Borrowing, the Swing Loan Lender shall, unless it determines that any
applicable condition specified in Article 3 has not been satisfied, make
available the amount of such Swing Loan Borrowing, in Federal or other funds
immediately available in New York City, to the Borrower at the Swing Loan
Lender's address specified in or pursuant to Section 9.01.

     (c)  Interest. Each Swing Loan shall bear interest on the outstanding
principal amount thereof, for each day during each Interest Period applicable
thereto, at a rate per annum equal to the sum of the Applicable Margin for
Revolving Euro-Dollar Loans for such day plus the New York Interbank Offered
Rate applicable to such Interest Period. Interest for each Interest Period shall
be payable on the last day thereof. Any overdue principal of or interest on any
Swing Loan shall bear interest, payable on demand, for each day until paid at a
rate per annum equal to the sum of the Applicable Margin for Revolving Base Rate
Loans for such day plus the Base Rate for such day.

     The "New York Interbank Offered Rate" applicable to any Interest Period
means the rate per annum at which deposits in dollars are offered to the Swing
Loan Lender in the New York interbank market at approximately 12:00 Noon (New
York City time) on the first day of such Interest Period in an amount
approximately equal to the principal amount of the Swing Loan to which such
Interest Period is to apply and for a period of time comparable to such Interest
Period.

     (d)  Optional Prepayment. The Borrower may prepay the Swing Loans in whole
at any time, or from time to time in part in a principal amount of at least

                                       50

<PAGE>

$1,000,000, by giving notice of such prepayment to the Swing Loan Lender not
later than 1:00 P.M. (New York City time) on the date of prepayment and paying
the principal amount to be prepaid, together with accrued interest thereon to
the date of prepayment, to the Swing Loan Lender.

     (e)  Mandatory Prepayment. On the date of each Revolving Borrowing pursuant
to Section 2.01, the Administrative Agent shall apply the proceeds thereof to
prepay all Swing Loans then outstanding, together with interest accrued thereon
to the date of prepayment.

     (f)  Payments. All payments to the Swing Loan Lender under this Section
2.17 shall be made to it at its address specified in or pursuant to Section
9.01, in Federal or other funds immediately available in New York City, not
later than 2:00 P.M. (New York City time) on the date of payment.

     (g)  Refunding Unpaid Swing Loans. If (x) the Swing Loans are not paid in
full on their Maturity Date, (y) the Swing Loans become immediately due and
payable pursuant to Article 6, or (z) the Swing Loan Lender (in its discretion)
elects to exercise its rights under this subsection (g), the Administrative
Agent shall (if requested to do so by the Swing Loan Lender), by notice to the
Revolving Lenders (including the Swing Loan Lender, in its capacity as a
Revolving Lender), require each Revolving Lender to pay to the Administrative
Agent for the account of the Swing Loan Lender an amount equal to such Revolving
Lender's Revolving Credit Percentage of the aggregate unpaid principal amount of
the Swing Loans then outstanding. Such notice shall specify the date on which
such payments are to be made, which shall be the first Domestic Business Day
after such notice is given. Not later than 12:00 Noon (New York City time) on
the date so specified, each Revolving Lender shall pay the amount so notified to
it to the Administrative Agent at its address specified in or pursuant to
Section 9.01, in Federal or other funds immediately available in New York City.
Promptly upon receipt thereof, the Administrative Agent shall remit such amounts
to the Swing Loan Lender. The amount so paid by each Revolving Lender shall
constitute a Revolving Base Rate Loan to the Borrower and shall be applied by
the Swing Loan Lender to repay the outstanding Swing Loans.

     (h)  Purchase of Participations in Swing Loans. If at the time Revolving
Loans would have otherwise been made pursuant to Section 2.17(g), one of the
events described in Section 6.01(h) or 6.01(i) with respect to the Borrower
shall have occurred and be continuing or the Revolving Commitments shall have
terminated, each Revolving Lender shall, on the date such Revolving Loans would
have been made pursuant to the notice referred to in Section 2.17(g) (the
"Refunding Date"), purchase an undivided participating interest in the relevant
Swing Loan in an amount equal to such Revolving Lender's Revolving Credit
Percentage of the principal amount of such Swing Loan. On the Refunding Date,
each Revolving Lender shall transfer to the Swing Loan Lender, in immediately
available funds, such amount.

                                       51

<PAGE>

     (i)  Payments on Participated Swing Loans. Whenever, at any time after the
Swing Loan Lender has received from any Revolving Lender such Revolving Lender's
payment pursuant to Section 2.17(h), the Swing Loan Lender receives any payment
on account of the Swing Loan in which the Revolving Lenders have purchased
participations pursuant to Section 2.17(h), the Swing Loan Lender will promptly
distribute to each such Revolving Lender its ratable share of such payment
(appropriately adjusted, in the case of interest payments, to reflect the period
of time during which such Revolving Lender's participating interest was
outstanding and funded); provided that in the event that such payment received
by the Swing Loan Lender is required to be returned, such Revolving Lender will
return to the Swing Loan Lender any portion thereof previously distributed to it
by the Swing Loan Lender.

     (j)  Obligations to Refund or Purchase Participations in Swing Loans
Absolute. Each Revolving Lender's obligation to transfer the amount of a
Revolving Loan to the Swing Loan Lender as provided in Section 2.17(g) or to
purchase a participating interest pursuant to Section 2.17(h) shall be absolute
and unconditional and shall not be affected by any circumstance, including,
without limitation, (i) any set-off, counterclaim, recoupment, defense or other
right which such Revolving Lender, the Borrower or any other Person may have
against the Swing Loan Lender or any other Person, (ii) the occurrence or
continuance of a Default or an Event of Default or the termination or reduction
of any Commitments, (iii) any adverse change in the condition (financial or
otherwise) of the Borrower or any other Person, (iv) any breach of this
Agreement by the Borrower, any other Lender or any other Person or (v) any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing.

     Section 2.18.  Stop Issuance Notice. If the Required Banks determine at any
time that the conditions set forth in Section 3.02 would not be satisfied in
respect of a Revolving Borrowing at such time, then the Required Banks may
request that the Administrative Agent issue a "Stop Issuance Notice", and the
Administrative Agent shall issue such notice to the Swing Loan Lender and to
each Issuing Bank. Such Stop Issuance Notice shall be withdrawn upon a
determination by the Required Banks that the circumstances giving rise thereto
no longer exist. No Swing Loan shall be made and no Letter of Credit shall be
issued while a Stop Issuance Notice is in effect. The Required Banks may request
issuance of a Stop Issuance Notice only if there is a reasonable basis therefor,
and shall consider reasonably and in good faith a request from the Borrower for
withdrawal of the same on the basis that the conditions in Section 3.02 are
satisfied; provided that the Administrative Agent, the Swing Loan Lender and the
Issuing Banks may and shall conclusively rely on any Stop Issuance Notice while
it remains in effect.

                                    ARTICLE 4
                         REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants that:

     Section 4.01.  Corporate Existence and Power. The Borrower is a corporation
duly incorporated, validly existing and in good standing under the laws of its
jurisdiction of incorporation, and has all corporate powers and all governmental
licenses, consents, authorizations and approvals required to carry on its
business as now conducted, except where the failure to have such licenses,
consents, authorizations and approvals could not reasonably be expected to have
a Material Adverse Effect.

     Section 4.02.  Corporate and Governmental Authorization; No Contravention.
The execution, delivery and performance by each Obligor of the Loan Documents to
which it is a party are within its corporate or other company powers, as the
case may be, have been duly authorized by all necessary corporate or other
company action, as the case may be, require no action by or in respect of, or
filing with, any governmental body, agency or official (other than the filing of

under, any provision of applicable law or regulation or of the certificate of
incorporation, by-laws or other constitutive documents of such Obligor or of any
agreement or instrument governing Material Debt or any other material agreement,
judgment, injunction, order, decree or other instrument binding upon the

Liens created under the Collateral Documents).

     Section 4.03.  Binding Effect; Liens Enforceable. (a) Each Loan Document
(other than the Notes) constitutes a legal, valid and binding agreement of each

the Borrower, in each case enforceable in accordance with its terms, subject to
applicable bankruptcy, insolvency or similar laws affecting creditors' rights
generally and general principles of equity (which principles may include implied
duties of good faith and fair dealing).

                                       55

<PAGE>

     (b)  The Collateral Documents create valid security interests or mortgage
liens in the Collateral purported to be covered thereby, which security
interests or mortgage liens are and will remain perfected security interests or

representations and warranties made by each Obligor in the Collateral Documents
to which it is a party is true and correct in all material respects.

     (f)  Since December 31, 2001, there has been no material adverse change in
the business, financial condition, assets, results of operations or liabilities
of the Borrower and its Consolidated Subsidiaries, considered as a whole.

     Section 4.05.  Litigation. There is no action, suit or proceeding
(including any action, suit or proceeding arising out of any Environmental Law)
pending against, or to the Borrower's knowledge threatened against or affecting,
the Borrower or any Subsidiary (including, for purposes of this Section, the
Borrower Joint Ventures) before any court or arbitrator or any governmental
body, agency or official which could reasonably be expected to have a Material
Adverse Effect, or which in any manner draws into question the validity or
enforceability of any Loan Document.

     Section 4.06.  Compliance with Laws. (a) Each of the Borrower and its
Subsidiaries (including, for purposes of this Section, the Borrower Joint
Ventures) is in compliance in all material respects with all laws, regulations
and orders of any governmental authority applicable to it or its property
(including Environmental Laws), except for those failures to comply that could
not reasonably be expected to have a Material Adverse Effect.

     (b)  Each member of the ERISA Group has fulfilled its obligations under the
minimum funding standards of ERISA and the Internal Revenue Code with respect to
each Plan and is in compliance (except where the failure to so comply could not
reasonably be expected to have a Material Adverse Effect) with the presently
applicable provisions of ERISA and the Internal Revenue Code with respect to
each Plan. Except as reflected in the PBGC Settlement Agreement, no member of
the ERISA Group has (i) sought a waiver of the minimum funding standard under
Section 412 of the Internal Revenue Code in respect of any Plan, (ii) failed to
make any contribution or payment to any Plan or Multiemployer Plan, or made any
amendment to any Plan, which has resulted or could result in the imposition of a
Lien or the posting of a bond or other security under ERISA or the Internal
Revenue Code or (iii) incurred any liability under Title IV of ERISA other than
a liability to the PBGC for premiums under Section 4007 of ERISA.

     Section 4.07.  Environmental Matters. In the ordinary course of its
business, the Borrower conducts an ongoing review of the effect of Environmental
Laws on the business, operations and properties of the Borrower and its
Subsidiaries, in the course of which it identifies and evaluates associated
liabilities and costs (including, without limitation, any capital or operating
expenditures required for clean-up or closure of properties presently or
previously owned, any capital or operating expenditures required to achieve or
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat,

                                       57

<PAGE>

any costs or liabilities in connection with off-site disposal of wastes or
Hazardous Substances and any actual or potential liabilities to third parties,
including employees, and any related costs and expenses). On the basis of this
review, the Borrower has reasonably concluded that such associated liabilities
and costs, including the costs of complying with Environmental Laws, could not
reasonably be expected to have a Material Adverse Effect.

     Section 4.08.  Taxes. The Borrower and its Subsidiaries (including, for
purposes of this Section, the Borrower Joint Ventures) have filed all United
States Federal income tax returns and all other material tax returns which are
required to be filed by them and have paid or accrued all taxes shown to be due
such returns or on any assessment received by the Borrower or any Subsidiary and
required to be paid or accrued by it, except to the extent that any such taxes
are being contested in good faith by appropriate proceedings.

     Section 4.09.  Subsidiaries. (a) Each of the Borrower's Significant
Subsidiaries (including, for purposes of this Section, the Borrower Joint
Ventures) is duly organized, validly existing and, where applicable, in good
standing under the laws of its jurisdiction of organization, and has the
constitutive powers and all governmental licenses, authorizations, consents and
approvals required to carry on its business as now conducted, except where the
failure to have such licenses, consents, authorizations and approvals could not
reasonably be expected to have a Material Adverse Effect. The Borrower has no
Significant Subsidiaries which are not either Foreign Subsidiaries, JV
Subsidiaries or, subject to Section 5.19(d)(v), Subsidiary Guarantors.

     (b)  Schedule 4.09 sets forth a correct list of each Subsidiary (including
each Borrower Joint Venture) of the Borrower as of the Restatement Date,

an "investment company" within the meaning of the Investment Company Act of
1940, as amended, (ii) a "holding company" or a "subsidiary company" of a
holding company within the meaning of the Public Utility Holding Company Act of
1935, as amended, or (iii) otherwise subject to any regulatory scheme (other
than Regulation U) which restricts its ability to incur or guarantee debt.

     Section 4.11.  Full Disclosure. The Information Memorandum does not contain
on the date hereof any material misstatement of fact or omit to state any
material fact necessary to make the statements contained therein, in light of
the circumstances under which they were made, not misleading; provided, however,
to the extent any such information was based on or constituted a forecast or
projection, the Borrower represents that it acted in good faith and utilized
information available to it at the time the Information Memorandum was prepared

                                       58

and assumptions believed by it to be reasonable in light of the then current and
foreseeable business conditions of the Borrower and its Subsidiaries.

in its business in good working order and condition, ordinary wear and tear
excepted, provided that no item of property need be so kept if the failure to
keep it so individually or in the aggregate with all other items not so kept by
the Borrower and its Subsidiaries could not reasonably be expected to have a
Material Adverse Effect.

     (b)  The Borrower will maintain, and will cause each of its Subsidiaries
to maintain (either in the Borrower's name or in such Subsidiary's own name)
insurance on all their respective properties consistent with the insurance
maintained on the date hereof or otherwise in at least such amounts (with no
materially greater risk retention) and against at least such risks as are

cause each Subsidiary to comply, in all material respects with all applicable
laws, ordinances, rules, regulations and requirements of governmental
authorities (including, without limitation, Environmental Laws and ERISA and the

therewith is contested in good faith by appropriate proceedings or where the
failure to do so, individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect.

effect to such merger, no Default shall exist or (ii) any Subsidiary from
merging with any Person if the entity surviving the merger is such Subsidiary or

Default shall exist. The Borrower will not sell or otherwise dispose of all or
substantially all of its assets to any other Person or Persons. Prior to the
Mandatory Prepayment Release Date, the Borrower will not, and will not permit

therefor is not less than the fair market value of the related asset (as
determined in good faith by the chief financial officer of the Borrower) and
(ii) the consideration therefor consists solely of cash or cash equivalents and
notes and equity securities, such notes and equity securities having an
aggregate value not to exceed 15% of the aggregate amount of consideration
received by the Borrower and its Subsidiaries with respect to such Asset Sale;

     (d)  The Borrower will:

            (i)     cause each Person which becomes a Significant Subsidiary
     (excluding any Borrower Joint Venture, JV Subsidiary, Foreign Subsidiary,
     Special Purpose Subsidiary, or Subject Assets Transferee) after the Closing

     interest to 50% and (y) in the case of each such Borrower Joint Venture, to
     the admission of additional partners or members, as the case may be, so
     long as the product of (I) the EBITDA of such Borrower Joint Venture,
     calculated on a pro forma basis (without credit for anticipated expense
     reductions or similar synergies) for its then most recent fiscal year for
     which financial statements are available multiplied by (II) the percentage
     representing the Borrower's direct and indirect ownership in such Borrower
     Joint Venture (the "EBITDA Product"), calculated after giving effect to
     such admission of any additional partner or member, is not less than the
     EBITDA Product calculated before giving effect to such admission); provided
     that the Borrower may sell all (but not less than all) of its direct or
     indirect ownership interests in LCR in compliance with Section 5.07;

          (iii)     cause each Person which becomes a JV Subsidiary (other than
     a Foreign Subsidiary) after the Closing Date, to enter into a JV

                                       70

<PAGE>

     Subsidiary Security Agreement and any other agreements, each in form and
     substance satisfactory to the Administrative Agent, as may be necessary or
     desirable in order to grant perfected first priority security interests
     (subject to Permitted Liens) upon its rights to receive distributions from
     any Borrower Joint Venture in which it holds an equity interest, to secure
     the obligations under the Loan Documents;

           (iv)     pledge, or cause to be pledged, pursuant to the Borrower

     other equity interests of such Subsidiary owned directly by the Borrower
     and (y) in the case of any Foreign Subsidiary which becomes a Significant
     Subsidiary of the Borrower or a Subject Assets Transferee after the Closing
     Date, to the extent permitted by applicable law, 65% of the voting stock or
     other voting equity interests of such Foreign Subsidiary, and 100% of any
     other capital stock or other equity interest, owned directly by the
     Borrower; and

            (v)     take, and cause the appropriate Subsidiaries to take, such
     actions as may be necessary or desirable to effect the steps required by
     the foregoing paragraphs (i), (ii), (iii) and (iv) as soon as practicable
     and in any event within 10 Domestic Business Days after the day on which
     the Borrower is required to deliver financial statements pursuant to
     Section 5.01(a) and 5.01(b) with respect to the Fiscal Quarter during which
     the event requiring such steps occurs, including without limitation (x)
     executing and delivering, or causing the appropriate Subsidiaries to
     execute and deliver, to the Administrative Agent such number of copies as
     the Administrative Agent may specify of such supplements and other
     documents and (y) delivering, or causing such Subsidiaries to deliver, such
     certificates, evidences of corporate action, legal opinions or other

     satisfaction of the Borrower's obligations under this Section.

     Section 5.20.  Restrictions on Borrower Joint Ventures. The Borrower shall
use its best efforts, including, without limitation, by voting (through the JV
Subsidiaries) its indirect interest in any Borrower Joint Venture at any
meetings of the respective governing bodies of such Borrower Joint Venture, to:

     (a)  limit annual expenditures for fixed assets by Equistar and LCR to an
aggregate amount of $400,000,000; provided that if the aggregate amount of such
expenditures for fixed assets actually made in any calendar year indicated above
shall be less than $400,000,000 then the amount of such shortfall may be added
to the amount of such expenditures for fixed assets permitted for the
immediately

                                       71

<PAGE>

succeeding calendar year; and provided further that expenditures in any year may
exceed the foregoing annual limitation so long as the aggregate amount of all
such excesses for all years during the term of this Agreement does not exceed
$500,000,000; and provided further that the limitations set forth in this
Section 5.20(a) shall not apply to (and calculations hereunder shall exclude)
(x) expenditures for fixed assets in respect of projects for the sole account
of, and funded exclusively by, partners or members of such Borrower Joint
Ventures other than the Borrower or (y) expenditures of casualty insurance or
condemnation proceeds;

     (b)  maintain without material change (i) the cash distribution policy of
Equistar as stated in the Equistar Partnership Agreement as in effect on the
Closing Date and (ii) the cash distribution policy (as may be adjusted in
connection with the LCR Recapitalization) of LCR as stated in the LCR
Partnership Agreement as in effect on the Closing Date;

     (c)   limit the Debt that any of Equistar or LCR creates, incurs, assumes
or permits to exist (exclusive of Debt owing to the Borrower or a Subsidiary) to
an aggregate outstanding principal amount which, together with all other
outstanding Debt of such Borrower Joint Venture, does not exceed (i) in the case
of Equistar, $3,100,000,000 and (ii) in the case of LCR, $1,750,000,000 plus, in
each case, the amount of any Additional JV Debt;

     (d)   prevent each of Equistar and LCR from, directly or indirectly,
entering into, incurring or permitting to exist any agreement or other
arrangement with any Person that prohibits, restricts or imposes any condition
upon the ability of such Borrower Joint Venture to pay dividends or other
distributions to, or to make or repay loans or advances to, the Borrower or any
JV Subsidiary, which restrictions or conditions are materially more restrictive
than those contained in agreements to which such Borrower Joint Venture is a
party set forth in Schedule 5.20, as in effect on the Closing Date; and

     (e)   maintain the rights of (i) Lyondell Petrochemical G.P. Inc. to
appoint the chief executive officer of Equistar, as provided in the Equistar
Partnership Agreement and (ii) Lyondell Refining Company to appoint, together
with CITGO Gulf Coast Refining, Inc., the chief executive officer of LCR, as

           (iv)     any Liens arising under the Collateral Documents on the
     Subject Assets not released in accordance with paragraph (iii) will be
     subordinate to any Asset Sale Lien on such Subject Assets.

     (b)  The provisions of subsection (a) are subject to the following
conditions:

            (i)     at the time of such Major Asset Sale, the Restricted Period
     shall have ended;

           (ii)     at the time of such Major Asset Sale and after giving effect
     thereto (on a pro forma basis for purposes of Section 5.11), no Default
     shall exist;

          (iii)     the sum of the gross cash proceeds received by the Borrower
     in respect of such Major Asset Sale plus the value of the interest of the
     Borrower in the Subject Assets Transferee (if any) after giving effect to
     such Major Asset Sale is not less than the value (as determined by the
     Board of Directors of the Borrower) of the portion of the Subject Assets
     transferred by the Borrower in connection with such Major Asset Sale;

           (iv)     the Borrower directly or indirectly is the operator of the
     Subject Assets in which it or a Subject Assets Transferee retains an

Subsidiary, Debt in an aggregate principal amount not to exceed (x) $50,000,000

permitted solely by clause (g) of Section 5.10 at such time less (z) the
aggregate outstanding principal amount of Debt secured by Liens permitted solely
by clause (j) of Section 5.09 at such time).

     (d)  For purposes of this Section 5.22, the following terms have the
following respective meanings:

          "Acquiring Person" means a Person other than a Subject Assets
     Transferee which acquires (i) all or a portion of the Subject Assets or
     (ii) an interest in a Subject Assets Transferee in connection with a Major
     Asset Sale.

          "Asset Sale Lien" means a Lien on the Subject Assets (including as a
     Lien for this purpose contractual rights with respect to the operation of
     the Subject Assets) arising in connection with a Major Asset Sale in favor
     of the Acquiring Person (or an affiliate thereof) which Lien does not
     secure any Debt.

          "Major Asset Sale" means an Asset Sale designated by the Borrower by
     prior notice to the Administrative Agent as a Major Asset Sale, so long as
     in connection therewith (i) the conditions specified in subsection (b) are
     satisfied and (ii) the Borrower receives Net Cash Proceeds in an aggregate
     amount not less than $1,000,000,000 (which shall be deemed Net Cash
     Proceeds of such Major Asset Sale for purposes of Section 2.04(d)). For
     this purpose (i) a transaction which produces substantially the same
     economic result as a sale of a partial interest in an asset, as might be
     achieved, for instance, through contractual arrangements allocating future
     revenues and costs attributable to the asset, shall be deemed an Asset Sale
     even though there may be no change in title to the asset or in the
     ownership of the Person which has title to the asset and (ii) a subsequent
     related transaction with the same Acquiring Person (or an Affiliate
     thereof) contemplated by the terms of the initial Major Asset Sale with
     such Person shall, for purposes of determining the applicability of and
     compliance with this Section, be deemed a single cumulative transaction.

          "Subject Assets" means, with respect to any Major Asset Sale, the
     assets which are the subject of such Major Asset Sale.

          "Subject Assets Transferee" means any Consolidated Subsidiary or
     Borrower Joint Venture which becomes the owner of the Subject Assets in
     connection with a Major Asset Sale.

     (e)  Nothing in this Section limits the ability of the Borrower and its
Subsidiaries to sell assets (including Collateral) in compliance with Section
5.07

                                       74

<PAGE>

in transactions which do not constitute Major Asset Sales, and to obtain a
release of Collateral pursuant to the last sentence of Section 9.05(b) in
connection with any such sale.

     Section 5.23.  Capital Expenditures. For each Fiscal Year of the Borrower
ending during the Restricted Period, Capital Expenditures of the Borrower and
its Consolidated Subsidiaries will not exceed the applicable Limit Amount set
forth in the table below, plus, for any such Fiscal Year, the amount if any (in
no case to exceed $25,000,000) by which their Capital Expenditures for the
immediately preceding Fiscal Year are less than the amount permitted hereunder:

                    FISCAL YEAR                    LIMIT AMOUNT

     Section 6.01.  Events of Default. If one or more of the following events
("Events of Default") shall have occurred and be continuing:

          (a)       the Borrower shall fail (i) to reimburse any drawing under
     any Letter of Credit when required hereunder or (ii) to pay when due any
     principal of any Loan;

     any fee or any other amount (other than an amount referred to in clause (a)

     when and as the same shall become due and payable, and such failure shall
     continue unremedied for a period of five Domestic Business Days;

          (c)       the Borrower shall fail to observe or perform any covenant
     contained in Section 5.01(f) or Section 5.07 through 5.18 or 5.20 through
     5.23, inclusive;

          (d)       the Borrower shall fail to observe or perform any covenant
     or agreement (other than those covered by clause 6.01(a), 6.01(b) or
     6.01(c) or above) contained in this Agreement or any other Loan Document or
     any amendment hereof or thereof for 30 days after the

                                       75

<PAGE>

     Administrative Agent gives notice thereof to the Borrower at the request of
     any Lender;

          (e)       any representation, warranty, certification or statement
     made by any Obligor in any Loan Document or any amendment thereof or in any
     certificate delivered pursuant to any Loan Document shall prove to have
     been incorrect in any material respect when made (or deemed made);

          (f)       the Borrower and its Subsidiaries shall fail to make one or
     more payments aggregating more than $50,000,000 in respect of Debt or
     Derivatives Obligations when due or within any applicable grace period;

          (g)       any event or condition shall occur which results in the
     acceleration of the maturity of any Material Debt or enables (or, with the
     giving of notice or lapse of time or both, would enable) the holder of such
     Debt or any Person acting on such holder's behalf to accelerate the
     maturity thereof; provided that (i) an event or condition which does not
     presently enable such holder or other Person to accelerate the maturity of
     such Debt and which is subsequently waived or cured will then no longer
     constitute an Event of Default hereunder; (ii) the existence or exercise of
     rights of holders of Debt under the Medium Term Notes to require repurchase
     thereof arising from the admission of subsidiaries of Occidental Chemical
     Corp. to Equistar shall not give rise to a Default under this subsection;
     and (iii) no Event of Default shall arise under this clause 6.01(g) in
     respect of Debt which is Guaranteed by, but is not otherwise Debt of, the
     Borrower or any Significant Subsidiary (including for this purpose the
     Borrower Joint Ventures);

          (h)       (i) the Borrower or any Significant Subsidiary (including
     for this purpose the Borrower Joint Ventures, but excluding LCR so long as
     LCR is not at the time a "Significant Subsidiary" for purposes of the
     instruments governing the Senior Notes or the Senior Subordinated Notes),
     shall commence a voluntary case or other proceeding seeking liquidation,
     reorganization or other relief with respect to itself or its debts under
     any bankruptcy, insolvency or other similar law now or hereafter in effect
     or seeking the appointment of a trustee, receiver, liquidator, custodian or
     other similar official of it or any substantial part of its property, or
     shall consent to any such relief or to the appointment of or taking
     possession by any such official in an involuntary case or other proceeding
     commenced against it, or shall make a general assignment for the benefit of
     creditors, or (ii) shall fail generally to pay its debts as they become
     due, or (ii) shall take any corporate action to authorize any of the
     foregoing;

          (i)       an involuntary case or other proceeding shall be commenced
     against the Borrower or any Significant Subsidiary (including for this

     not at the time a "Significant Subsidiary" for purposes of the instruments
     governing the Senior Notes or the Senior Subordinated Notes), seeking
     liquidation, reorganization or other relief with respect to it or its debts
     under any bankruptcy, insolvency or other similar law now or hereafter in
     effect or seeking the appointment of a trustee, receiver, liquidator,
     custodian or other similar official of it or any substantial part of its
     property, and such involuntary case or other proceeding shall remain
     undismissed and unstayed for a period of 60 days; or an order for relief
     shall be entered against the Borrower or any Significant Subsidiary
     (including for this purpose the Borrower Joint Ventures, but excluding LCR
     so long as LCR is not at the time a "Significant Subsidiary" for purposes
     of the instruments governing the Senior Notes or the Senior Subordinated
     Notes), under the federal bankruptcy laws as now or hereafter in effect;

          (j)       any member of the ERISA Group shall fail to pay when due an
     amount or amounts which it shall have become liable to pay under Title IV
     of ERISA; or notice of intent to terminate a Plan shall be filed under
     Title IV of ERISA by any member of the ERISA Group, any plan administrator
     or any combination of the foregoing; or the PBGC shall institute
     proceedings under Title IV of ERISA to terminate, to impose liability
     (other than for premiums under Section 4007 of ERISA) in respect of, or to
     cause a trustee to be appointed to administer, any Plan; or a condition
     shall exist by reason of which the PBGC would be entitled to obtain a
     decree adjudicating that any Plan must be terminated; or there shall occur
     a complete or partial withdrawal from, or a default, within the meaning of
     Section 4219(c)(5) of ERISA, with respect to, one or more Multiemployer
     Plans which could cause one or more members of the ERISA Group to incur a
     current payment obligation, if any of the foregoing could reasonably be
     expected to have a Material Adverse Effect (it being understood that the
     fact of the Borrower becoming a party to the PBGC Settlement Agreement is
     not, in itself, expected to have a Material Adverse Effect);

          (k)       judgments or orders for the payment of money exceeding
     $50,000,000 in aggregate amount (exclusive of amounts covered by insurance
     as to which the carrier has not contested coverage) shall be rendered
     against the Borrower or any Subsidiary (including for this purpose the
     Borrower Joint Ventures) and such judgments or orders shall continue
     undischarged, unsatisfied and unstayed for a period of 30 days; or
     enforcement remedies in respect of any such judgments or orders shall be
     commenced;

          (l)       a Change of Control of the Borrower shall have occurred;

<PAGE>

          (m)       (i) any Lien created by any of the Collateral Documents
     shall at any time fail to constitute a valid and (to the extent required by
     the Collateral Documents) perfected Lien on all the Collateral purported to
     be subject thereto, securing the obligations purported to be secured
     thereby, with the priority required by the Loan Documents, or (ii) any
     Obligor shall so assert in writing; provided that if a failure of the sort
     described in clause 6.01(m) is susceptible of cure, no Event of Default
     shall arise under this clause 6.01(m) with respect thereto until 30 days
     after notice of such failure shall have been given to the Borrower by the
     Administrative Agent;

          (n)       any Guarantee by any Subsidiary Guarantor pursuant to the
     Subsidiary Guarantee shall cease for any reason (other than pursuant to a
     transaction permitted hereunder) to be in full force and effect, or any
     Obligor shall so assert in writing;

          then, and in every such event, the Administrative Agent shall:

               (i)    if requested by Lenders having more than 50% in aggregate
          amount of the Commitments, by notice to the Borrower terminate the
          Commitments and they shall thereupon terminate; and

              (ii)    if requested by Lenders holding more than 50% in aggregate
          outstanding principal amount of the Loans, by notice to the Borrower
          declare all, or a pro rata portion of all, principal of the Loans
          (together in each case with accrued interest thereon) to be, and such
          principal of the Loans (together with accrued interest thereon) shall
          thereupon become, immediately due and payable without presentment,
          demand, protest or other notice of any kind, all of which are hereby
          waived by the Borrower;

provided that, if any Event of Default specified in clause 6.01(h)(i) or 6.01(i)
occurs with respect to the Borrower, then without any notice to the Borrower or
any other act by the Administrative Agent or the Lenders, the Commitments shall
thereupon terminate and the entire principal amount of the Loans (together with
accrued interest thereon) shall become immediately due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby waived by the Borrower.

     Section 6.02.  Notice of Default. The Administrative Agent shall give
notice to the Borrower under Section 6.01(d) or 6.01(m) promptly upon being
requested to do so by any Lender and shall thereupon notify all the Lenders
thereof.

                                       78

<PAGE>

     Section 6.03.  Cash Cover. The Borrower agrees, in addition to the
provisions of Section 6.01 hereof, that upon the occurrence and during the
continuance of any Event of Default, it shall, if requested by the
Administrative Agent upon the instruction of Lenders having more than 50% of the
Letter of Credit Liabilities, pay to the Administrative Agent an amount in
immediately available funds (which funds shall be held as collateral pursuant to
arrangements satisfactory to the Administrative Agent) equal to the aggregate
amount available for drawing under all Letters of Credit then outstanding at
such time; provided that, upon the occurrence of any Event of Default specified
in Section 6.01(h) or 6.01(i) with respect to the Borrower, the Borrower shall
pay such amount forthwith without any notice or demand or any other act by the
Administrative Agent or the Lenders.

                                    ARTICLE 7
                                   THE AGENTS

     Section 7.01.  Appointment and Authorization. Each Lender irrevocably
appoints and authorizes the Administrative Agent to take such action as agent on
its behalf and to exercise such powers under the Loan Documents as are delegated
to the Administrative Agent by the terms hereof or thereof, together with all
such powers as are reasonably incidental thereto.

     Section 7.02.  Agents and Affiliates. Each financial institution serving as
an Agent shall have the same rights and powers under the Loan Documents as any
other Lender and may exercise or refrain from exercising the same as though it
were not an Agent, and such financial institution and its affiliates may accept
deposits from, lend money to and generally engage in any kind of business with
the Borrower or any Subsidiary or affiliate of the Borrower as if it were not an
Agent.

     Section 7.03.  Action by the Administrative Agent. The obligations of the
Administrative Agent hereunder are only those expressly set forth herein.
Without limiting the generality of the foregoing, the Administrative Agent shall
not be required to take any action with respect to any Default, except, as
expressly provided in Article 6.

     Section 7.04.  Consultation with Experts. The Administrative Agent may
consult with legal counsel (who may be counsel for any Obligor), independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken by it in good faith in accordance with
the advice of such counsel, accountants or experts.

     Section 7.05.  Liability of Agents. None of the Agents, their respective
affiliates, and the directors, officers, agents and employees of the Agents and
their respective affiliates shall be liable for any action taken or not taken by
it in

                                       79

<PAGE>

connection herewith (i) with the consent or at the request of the Required
Lenders (or such different number of Lenders as any provision hereof expressly
requires for such consent or request) or (ii) in the absence of its own gross
negligence or willful misconduct. None of the Agents, their respective
affiliates, and the directors, officers, agents and employees of the Agents and
their respective affiliates shall be responsible for or have any duty to
ascertain, inquire into or verify (i) any statement, warranty or representation
made in connection with this Agreement or any borrowing or issuance of a Letter
of Credit hereunder; (ii) the performance or observance of any of the covenants
or agreements of the Borrower; (iii) the satisfaction of any condition specified
in Article 3, except receipt of items required to be delivered to such Agent;
(iv) the validity, effectiveness or genuineness of any Loan Document or any
other instrument or writing furnished in connection herewith or (v) the
existence, validity or sufficiency of any Collateral. No Agent shall incur any
liability by acting in reliance upon any notice, consent, certificate, statement
or other writing (which may be a bank wire, telex, facsimile or similar writing)
believed by it to be genuine or to be signed by the proper party or parties.
Without limiting the generality of the foregoing, the use of the term "agent" in
this Agreement with reference to any Agent is not intended to connote any
fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law. Instead, such term is used merely as a matter of
market custom and is intended to create or reflect only an administrative
relationship between independent contracting parties.

     Section 7.06.  Indemnification. The Lenders shall, ratably in proportion to
their Commitments, indemnify each Agent, its affiliates and the directors,
officers, agents and employees of each such Agent and its affiliates (to the
extent not reimbursed by the Borrower) against any cost, expense (including
counsel fees and disbursements), claim, demand, action, loss or liability
(except such as result from such indemnitees' gross negligence or willful
misconduct) that such indemnitees may suffer or incur in connection with this
Agreement or any action taken or omitted by such indemnitees hereunder.

     Section 7.07.  Credit Decision. Each Lender acknowledges that it has,
independently and without reliance on the Arranger, any Co-Arranger, any Agent
or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Lender also acknowledges that it will, independently and without
reliance on any Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking any action under this Agreement.

     Section 7.08.  Successor Administrative Agents. The Administrative Agent
may resign at any time by giving notice thereof to the Lenders and the Borrower.
Upon any such resignation, the Required Lenders shall have the right to appoint
a successor for such resigning Administrative Agent. If no successor Agent shall

                                    80

<PAGE>

have been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the retiring Administrative Agent gives notice
of resignation, then the retiring Administrative Agent may, on behalf of the
Lenders, appoint a successor Administrative Agent, which shall be a commercial
bank organized or licensed under the laws of the United States or of any State
thereof and having a combined capital and surplus of at least $100,000,000. Upon
the acceptance of its appointment as Administrative Agent hereunder by a
successor, such successor Administrative Agent shall thereupon succeed to and
become vested with all the rights and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. After any Administrative Agent's resignation
hereunder, the provisions of this Article shall inure to its benefit as to
actions taken or omitted to be taken by it while it was an Administrative Agent.

     Section 7.09.  Administrative Agent's Fees. The Borrower shall pay to the
Administrative Agent for its own account fees in the amounts and at the times
previously agreed upon in writing by the Borrower and the Administrative Agent.

     Section 7.10.  Co-Syndication Agents, Co-Documentation Agents and
Arrangers. No Agent other than the Administrative Agent and no Arranger shall
have any responsibility, obligation or liability whatsoever under the Loan
Documents in such capacity.

                                   ARTICLE 8
                             CHANGE IN CIRCUMSTANCES

     Section 8.01.  Basis for Determining Interest Rate Inadequate or Unfair. If
on or before the first day of any Interest Period for any Euro-Dollar Loans of
any Class:

     (a)  the Administrative Agent is advised by the Reference Lenders that
deposits in dollars in the applicable amounts are not being offered to the
Reference Lenders in the London interbank market for such Interest Period, or

     (b)  Lenders having at least 50% in aggregate amount of the Commitments of
such Class (or, in the case of Term Lenders, holding at least 50% of the
aggregate outstanding principal amount of the affected Class of Term Loans)
advise the Administrative Agent that the London Interbank Offered Rate as
determined by the Administrative Agent will not adequately and fairly reflect
the cost to such Lenders of funding their Euro-Dollar Loans for such Interest
Period,

     the Administrative Agent shall forthwith give notice thereof to the
Borrower and the Lenders, whereupon until the Administrative Agent notifies the
Borrower that the circumstances giving rise to such suspension no longer exist,
(i)

                                       81

<PAGE>

the obligations of the Lenders to make Euro-Dollar Loans or to continue or
convert outstanding Loans as or into Euro-Dollar Loans, as the case may be,
shall be suspended and (ii) each outstanding Euro-Dollar Loan of the affected
Class shall be converted into a Base Rate Loan on the last day of the then
current Interest Period applicable thereto. Unless the Borrower notifies the
Administrative Agent at least one Domestic Business Day before the date of any
affected Borrowing for which a Notice of Borrowing has previously been given
that it elects not to borrow on such date, such Borrowing shall instead be made
as a Base Rate Borrowing.

     Section 8.02.  Illegality. If, after the date hereof, the adoption of any
applicable law, rule or regulation, or any change in any applicable law, rule or
regulation, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency (including without
limitation the National Association of Insurance Commissioners (the "NAIC"))
charged with the interpretation or administration thereof, or compliance by any
Lender (or its Euro-Dollar Lending Office) with any request or directive made or
issued after the date hereof (whether or not having the force of law) of any
such authority, central bank or comparable agency, shall make it unlawful or
impossible for any Lender (or its Euro-Dollar Lending Office) to make, maintain
or fund its Euro-Dollar Loans and such Lender shall so notify the Administrative
Agent, the Administrative Agent shall forthwith give notice thereof to the other
Lenders and the Borrower, whereupon until such Lender notifies the Borrower and
the Administrative Agent that the circumstances giving rise to such suspension
no longer exist, the obligation of such Lender to make Euro-Dollar Loans, or to
convert outstanding Loans into Euro-Dollar Loans or continue outstanding Loans
as Euro-Dollar Loans, shall be suspended. Before giving any notice to the
Administrative Agent pursuant to this Section, such Lender shall designate a
different Euro-Dollar Lending Office if such designation will avoid the need for
giving such notice and will not, in the judgment of such Lender, be otherwise
disadvantageous to such Lender. If such notice is given, each Euro-Dollar Loan
of such Lender then outstanding shall be converted to a Base Rate Loan either
(i) on the last day of the then current Interest Period applicable to such
Euro-Dollar Loan if such Lender may lawfully continue to maintain and fund such
Loan as a Euro-Dollar Loan to such day or (ii) immediately if such Lender shall
determine that it may not lawfully continue to maintain and fund such Loan as a
Euro-Dollar Loan to such day. Interest and principal on any such Base Rate Loan
shall be payable on the same dates as, and on a pro rata basis with, the
interest and principal payable on the related Euro-Dollar Loans of the other
Lenders.

     Section 8.03.  Increased Cost and Reduced Return. (a) If after the date
hereof, the adoption of any applicable law, rule or regulation, or any change in
any applicable law, rule or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable

                                       82

<PAGE>

agency (including without limitation the NAIC) charged with the interpretation
or administration thereof, or compliance by any Lender (or its Applicable
Lending Office) with any request or directive made or issued after the date
hereof (whether or not having the force of law) of any such authority, central
bank or comparable agency, shall impose, modify or deem applicable any reserve
(including, without limitation, any such requirement imposed by the Board of
Governors of the Federal Reserve System, but excluding any such requirement with
respect to which such Lender is entitled to compensation during the relevant
Interest Period under Section 2.15), special deposit, insurance assessment or
similar requirement against assets of, deposits with or for the account of, or
credit extended by, any Lender (or its Applicable Lending Office) or shall
impose on any Lender (or its Applicable Lending Office) or on the London
interbank market any other condition affecting its Fixed Rate Loans, its Notes
or its obligation to make Fixed Rate Loans or its obligations hereunder in
respect of Letters of Credit and the result of any of the foregoing is to
increase the cost to such Lender (or its Applicable Lending Office) of making or
maintaining any Fixed Rate Loan, or of issuing or participating in any Letter of
Credit, or to reduce the amount of any sum received or receivable by such Lender
(or its Applicable Lending Office) under this Agreement or under its Note with
respect thereto, by an amount deemed by such Lender to be material, then, within
15 days after demand by such Lender (with a copy to the Administrative Agent),
the Borrower shall pay to such Lender such additional amount or amounts as will
compensate such Lender for such increased cost or reduction.

     (b)  If any Lender shall have determined that, after the date hereof, the
adoption of any applicable law, rule or regulation regarding capital adequacy,
or any change in any such law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or any request or directive regarding capital adequacy (whether or not
having the force of law) of any such authority, central bank or comparable
agency (including without limitation the NAIC), which adoption, change, request
or directive was effected after the date hereof, has or would have the effect of
reducing the rate of return on capital of such Lender (or its Parent) as a
consequence of such Lender's obligations hereunder to a level below that which
such Lender (or its Parent) could have achieved but for such adoption, change,
request or directive (taking into consideration its policies with respect to
capital adequacy) by an amount deemed by such Lender to be material, then from
time to time, within 15 days after demand by such Lender (with a copy to the
Administrative Agent), the Borrower shall pay to such Lender such additional
amount or amounts as will compensate such Lender (or its Parent) for such
reduction.

     (c)  Each Lender will promptly notify the Borrower and the Administrative
Agent of any event of which it has knowledge, occurring after the date hereof,
which will entitle such Lender to compensation pursuant to this

                                       83

<PAGE>

Section and will designate a different Applicable Lending Office if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the judgment of such Lender, be otherwise disadvantageous to
it. A certificate of any Lender claiming compensation under this Section and
setting forth the additional amount or amounts to be paid to it hereunder shall
be conclusive in the absence of manifest error. In determining such amount, such
Lender may use any reasonable averaging and attribution methods.

     Section 8.04.  Taxes. (a) For the purposes of this Section, the following
terms have the following meanings:

     "Taxes" means any and all present or future taxes, duties, levies, imposts,
deductions, charges or withholdings with respect to any payment by the Borrower
pursuant to this Agreement or under any Note, and all liabilities with respect
thereto, excluding (the "Excluded Taxes") (i) in the case of each Lender Party,
taxes imposed on its net income, and franchise, capital or similar taxes
(including branch profits taxes) imposed on it, by a jurisdiction under the laws
of which (or of a political subdivision of which) it is organized or in which
its principal executive office is located or in which its Applicable Lending
Office is located and (ii) in the case of each Lender, any United States
withholding tax imposed on such payment, but not excluding any portion of such
tax that exceeds the United States withholding tax which would have been imposed
on such a payment to such Lender under the laws and treaties in effect when such
Lender first becomes a party to this Agreement if that Lender is in compliance
with its obligations under Section 8.04(b).

     "Other Taxes" means any present or future stamp or documentary taxes and
any other excise or property taxes, or similar charges or levies, which arise
from any payment made pursuant to this Agreement or under any Note or from the
execution, delivery, registration or enforcement of, or otherwise with respect
to, any Loan Document other than Taxes and Excluded Taxes.

     (b)  All payments by the Borrower to or for the account of any Lender Party
hereunder or under any Note shall be made without deduction for any Taxes or
Other Taxes; provided that, if the Borrower shall be required by law to deduct
any Taxes or Other Taxes from any such payment, (i) the sum payable shall be
increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section) such Lender
Party receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law and (iv) the Borrower shall
promptly furnish to the Administrative Agent, at its address specified in or
pursuant to Section 9.01, the original or a certified copy of a receipt
evidencing payment thereof.

                                       84

<PAGE>

     (c)  The Borrower agrees to indemnify each Lender Party for the full amount
of Taxes and Other Taxes (including, without limitation, any Taxes or Other
Taxes imposed or asserted (whether or not correctly) by any jurisdiction on
amounts payable under this Section) paid by such Lender Party and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto. This indemnification shall be paid within 15 days after such Lender
Party makes demand therefor.

     (d)  Each Lender Party organized under the laws of a jurisdiction outside
the United States, (i) before it signs and delivers this Agreement in the case
of each Lender Party listed on the signature pages hereof and before it becomes
a Lender Party in the case of each other Lender Party, (ii) before it changes
the country where its Applicable Lending Office is located, (iii) from time to
time thereafter if requested in writing by the Borrower (but only so long as
such Lender Party remains lawfully able to do so), and (iv) at the time or times
prescribed by applicable law, shall provide each of the Borrower and the
Administrative Agent with (x) Internal Revenue Service form W-8 ECI or W-8 BEN,
as appropriate, or any successor form prescribed by the Internal Revenue
Service, certifying that such Lender Party is entitled to benefits under an
income tax treaty to which the United States is a party which exempts such
Lender Party from United States withholding tax or reduces the rate of
withholding tax on payments of interest for the account of such Lender Party or
certifying that the income receivable by it pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the United
States or (y) solely if such Lender is claiming exemption from United States
withholding tax under Section 871(h) or 881(c) of the Internal Revenue Code with
respect to payments of "portfolio interest", a Form W-8, or any successor form
prescribed by the Internal Revenue Service, and a certificate representing that
such Lender is not a bank for purposes of Section 881(c) of the Internal Revenue
Code, is not a 10-percent shareholder (within the meaning of Section
871(h)(3)(B) of the Internal Revenue Code) of the Borrower and is not a
controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Internal Revenue Code).

     (e)  For any period with respect to which a Lender Party has failed to
provide the Borrower or the Administrative Agent with the appropriate form
referred to in Section 8.04(d) (unless such failure is due to a change in
treaty, law or regulation occurring after the date on which such form originally
was required to be provided), such Lender Party shall not be entitled to
indemnification under Section 8.04(b) or 8.04(c) with respect to Taxes imposed
by the United States; provided that if a Lender Party, that is otherwise exempt
from or subject to a reduced rate of withholding tax, becomes subject to Taxes
because of its failure to deliver a form required hereunder, the Borrower shall
take such steps as such Lender Party shall reasonably request to assist such
Lender Party to recover such Taxes.

                                       85

<PAGE>

     (f)  If the Borrower is required to pay additional amounts to or for the
account of any Lender pursuant to this Section as a result of a change in law or
treaty occurring after such Lender first became a party to this Agreement, then
such Lender will, at the Borrower's request, change the jurisdiction of its
Applicable Lending Office if, in the judgment of such Lender, such change (i)
will eliminate or reduce any such additional payment which may thereafter accrue
and (ii) is not otherwise disadvantageous to such Lender.

     Section 8.05.  Base Rate Loans Substituted for Affected Euro-Dollar Loans.
If (i) the obligation of any Lender to make, or to continue or convert
outstanding Loans as or to, Euro-Dollar Loans has been suspended pursuant to
Section 8.02 or (ii) any Lender has demanded compensation under Section 8.03 or
8.04 with respect to its Euro-Dollar Loans, and in any such case the Borrower
shall, by at least five Euro-Dollar Business Days' prior notice to such Lender
through the Administrative Agent, have elected that the provisions of this
Section shall apply to such Lender, then, unless and until such Lender notifies
the Borrower that the circumstances giving rise to such suspension or demand for
compensation no longer exist, all Loans which would otherwise be made by such
Lender as (or continued as or converted to) Euro-Dollar Loans shall instead be
Base Rate Loans on which interest and principal shall be payable
contemporaneously with the related Euro-Dollar Loans of the other Lenders. If
such Lender notifies the Borrower that the circumstances giving rise to such
suspension or demand for compensation no longer exist, the principal amount of
each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first
day of the next succeeding Interest Period applicable to the related Euro-Dollar
Loans of the other Lenders.

     Section 8.06.  Substitution of Bank. If (i) the obligation of any Lender to
make or to convert or continue outstanding Loans as or into Euro-Dollar Loans
has been suspended pursuant to Section 8.02 or (ii) any Lender has demanded
compensation under Section 8.03 or 8.04, the Borrower shall have the right, with
the assistance of the Administrative Agent, to designate a substitute bank or
banks (which may be one or more of the Lenders) mutually satisfactory to the
Borrower and the Administrative Agent (and, in the case of a Revolving Lender,
the Issuing Banks and the Swing Loan Lender) to purchase for cash, pursuant to
an Assignment and Assumption Agreement in substantially the form of Exhibit D
hereto, the outstanding Loans and Letter of Credit Liabilities of such Lender
and assume the Commitment(s) of such Lender, without recourse to or warranty by,
or expense to, such Lender, for a purchase price equal to the principal amount
of all of such Lender's outstanding Loans and Reimbursement Obligations plus any
accrued but unpaid interest thereon and the accrued but unpaid fees for the
account of such Lender hereunder plus such amount, if any, as would be payable
pursuant to Section 2.11 if the outstanding Loans of such Lender were prepaid in
their entirety on the date of consummation of such assignment.

                                  MISCELLANEOUS

     Section 9.01.  Notices. (a) All notices, requests and other communications
to any party hereunder shall be in writing (including facsimile or similar
writing) and shall be given to such party: (i) in the case of the Borrower or
any Agent, at its address or facsimile number set forth on the signature pages
hereof, (ii) in the case of any Lender, at its address or facsimile number set
forth in its Administrative Questionnaire or (iii) in the case of any party, at
such other address or facsimile number as such party may hereafter specify for
the purpose by notice to the Administrative Agent and the Borrower. Each such
notice, request or other communication shall be effective if given by facsimile,
when transmitted to the facsimile number referred to in this Section and
confirmation of receipt is received, or if given by any other means, when
delivered at the address referred to in this Section; provided that notices to
the Administrative Agent under Article 2 or Article 8 shall not be effective
until received.

     (b)  Notices and other communications to the Lenders hereunder may be
delivered or furnished by electronic communications pursuant to procedures
approved by the Administrative Agent; provided that the foregoing shall not
apply to notices pursuant to Article 2 unless otherwise agreed by the
Administrative Agent and the applicable Lender. The Administrative Agent or the
Borrower may, in its discretion, agree to accept notices and other
communications to it hereunder by electronic communications pursuant to
procedures approved by it; provided that approval of such procedures may be
limited to particular notices or communications.

     (c)  Notices by the Borrower pursuant to Article 2 shall be irrevocable;
provided that, if a notice of optional or mandatory prepayment or termination or
reduction of Commitments pursuant to Section 2.04, 2.08 or 2.09 is expressed to
be contingent upon the consummation of a Reduction Event or other transaction,
such notice may be revoked by the Borrower, or the effective date thereof may be
postponed by a period of up to 30 days, in the event such transaction is delayed
or cancelled; provided further that in any such event (i) the Borrower shall
give the applicable Lenders through the Administrative Agent not less than three
Euro-Dollar Business Days' notice of the ultimate effective date of any such
notice and (ii) any such revocation or postponement of the effective date of a
notice shall be subject to the rights of the Lenders under Section 2.11.

     Section 9.02.  No Waivers. No failure or delay by any Lender Party
exercising any right, power or privilege hereunder or under any Note shall
operate as a waiver thereof nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The rights and remedies herein provided shall be
cumulative and not exclusive of any rights or remedies provided by law.

                                       87

     Section 9.03.  Expenses; Indemnification. (a) The Borrower shall pay (i)
all out-of-pocket expenses of the Agents, including fees and disbursements of
special counsel for the Agents, in connection with the preparation of the Loan
Documents, any waiver or consent thereunder or any amendment thereof or any
Default thereunder and (ii) if an Event of Default occurs, all out-of-pocket
expenses incurred by each Lender Party, including the fees and disbursements of
counsel, in connection with such Event of Default and collection, bankruptcy,
insolvency and other enforcement proceedings resulting therefrom.

     (b)  The Borrower agrees to indemnify each Lender Party, their respective
affiliates and the respective directors, officers, agents and employees of the
foregoing (each an "Indemnitee") and hold each Indemnitee harmless from and
against any and all liabilities, losses, damages, costs and expenses of any kind
(including without limitation reasonable expenses of investigation by engineers,
environmental consultants and similar technical personnel), including, without
limitation, the reasonable fees and disbursements of counsel, which may be
incurred by such Indemnitee in connection with any investigative, administrative
or judicial proceeding (whether or not such Indemnitee shall be designated a
party thereto) brought or threatened relating to or arising out of any Loan
Document or any actual or proposed use of any Commitments or any proceeds of
Loans hereunder; provided that no Indemnitee shall have the right to be
indemnified hereunder for (i) such Indemnitee's own gross negligence or willful
misconduct or (ii) liabilities, losses, damages, costs and expenses arising out
of a proceeding in which such Indemnitee and the Borrower are adverse parties
and in which the Borrower prevails on the merits, in each case as determined by
a court of competent jurisdiction.

     Section 9.04.  Set-Offs. (a) If (i) an Event of Default has occurred and is
continuing and Lenders holding more than 50% in aggregate unpaid principal
amount of the Loans have requested the Administrative Agent to declare the Loans
to be immediately due and payable pursuant to Section 6.01, or (ii) the Loans
have become immediately due and payable without notice as provided in Section
6.01, then each Lender is hereby authorized by the Borrower at any time and from
time to time, to the extent permitted by applicable law, without notice to the
Borrower (any such notice being expressly waived by the Borrower), to set off
and apply all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by such Lender
to or for the account of the Borrower against any obligations of the Borrower to
such Lender now or hereafter existing under this Agreement, regardless of
whether any such deposit or other obligation is then due and payable or is in
the same currency or is booked or otherwise payable at the same office as the
obligation against which it is set off and regardless of whether such Lender
shall have made any demand for payment under this Agreement. Each Lender agrees
promptly to notify the Borrower after any such set-off and application made by
such Lender; provided that any failure to give such notice shall not affect the
validity of such

                                       88

<PAGE>

setoff and application. The rights of the Lenders under this subsection are in
addition to any other rights and remedies which the Lenders may have.

     (b)  Each Lender agrees that if it shall, by exercising any right of
set-off or counterclaim or otherwise, receive payment of a proportion of the
aggregate amount of principal and interest then due with respect to the Loans
and Letter of Credit Liabilities held by it which is greater than the proportion
received by any other Lender in respect of the aggregate amount of principal and
interest then due with respect to the Loans and Letter of Credit Liabilities
held by such other Lender, the Lender receiving such proportionately greater
payment shall purchase such participations in the Loans held by the other
Lenders, and such other adjustments shall be made, as may be required so that
all such payments of principal and interest with respect to the Loans and Letter
of Credit Liabilities held by the Lenders shall be shared by the Lenders pro
rata; provided that nothing in this Section shall impair the right of any Lender
to exercise any right of set-off or counterclaim it may have and to apply the
amount subject to such exercise to the payment of indebtedness of the Borrower
other than its indebtedness in respect of the Loans; and provided further that
this Section shall not require sharing by the Swing Loan Lender of amounts
received in respect of Swing Loans pursuant to Section 2.17.

     Section 9.05.  Amendments and Waivers. (a) Any provision of this Agreement
or the Notes may be amended or waived if, but only if, such amendment or waiver
is in writing and is signed by the Borrower and the Required Lenders (and, if
the rights or duties of any Agent, any Issuing Bank or the Swing Loan Lender (in
such capacities) are affected thereby, by it); provided that no such amendment
or waiver shall:

            (i)     unless signed by all the Term Lenders, (A) reduce the
     principal of or rate of interest on any Term Loan or (B) postpone the date
     fixed for any payment of principal of or interest on any Term Loan,

           (ii)     unless signed by all the Revolving Lenders, (A) increase or
     decrease the Revolving Commitment of any Revolving Lender (except for a
     ratable decrease in the Revolving Commitments of all the Revolving
     Lenders), (B) reduce the principal of or rate of interest on any Revolving
     Loan or the amount to be reimbursed in respect of any Letter of Credit or
     any interest thereon or any fees with respect thereto, or (C) postpone the
     date fixed for any payment of any principal of or interest on any Revolving
     Loan or for reimbursement in respect of any Letter of Credit or any
     interest thereon or fees with respect thereto or any fees payable with
     respect to the Revolving Commitments or for the termination of any
     Revolving Commitment, or (except as expressly provided in Section 2.16) the
     expiry date of any Letter of Credit,

                                       89

<PAGE>

          (iii)     unless signed by all the Lenders, (A) change the percentage
     of the Commitments of any Class or of the aggregate unpaid principal amount
     of the Loans of any Class, or the number of Lenders, which shall be
     required for the Lenders or any of them to take any action under this
     Section or any other provision of this Agreement, (B) release any
     Subsidiary Guarantor from the Subsidiary Guarantee or permit termination of
     the Subsidiary Guarantee or (C) effect or permit the release of all or
     substantially all of the Collateral,

           (iv)     unless signed by Revolving Lenders holding, in the
     aggregate, Revolving Credit Percentages of greater than 50%, waive any
     condition to any Borrowing of Revolving Loan or issuance of Letter of
     Credit; or

            (v)     unless signed by a Designated Lender or its Designating
     Lender, subject such Designated Lender to any additional obligation or
     affect its rights hereunder (unless the rights of all the Lenders of the
     applicable Class hereunder are similarly affected).

     (b)  Any provision of the Collateral Documents or the Subsidiary Guarantee
may be amended or waived if, but only if, such amendment or waiver is in writing
and is signed by each Obligor party thereto and the Administrative Agent with
the consent of the Required Lenders; provided that no such amendment or waiver
shall, unless signed by all the Lenders, effect or permit a release of all or
substantially all of the Collateral, release any Subsidiary Guarantor from the
Subsidiary Guarantee or permit termination of the Subsidiary Guarantee.
Notwithstanding the foregoing, including Section 9.05(a)(iii), Subsidiary
Guarantees shall be terminated and Collateral (but not the proceeds thereof)
shall be released from the Lien of the Collateral Documents from time to time as
necessary to effect any sale of assets, including the sale of a Subsidiary
Guarantor, permitted by the Loan Documents, and the Administrative Agent shall
execute and deliver all release documents reasonably requested to evidence such
release.

     (c)  Each Lender party hereto consents to the execution and delivery by the
Administrative Agent of such amendments to the Collateral Documents as shall be
necessary or desirable in order to permit any Senior Notes to be secured by the
Collateral as contemplated by clause (iii) of the definition thereof.

     Section 9.06.  Successors; Participations and Assignments. (a) The
provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns, except that the
Borrower may not assign or otherwise transfer any of its rights under this
Agreement without the prior written consent of all the Lender Parties.

                                       90

     (b)  Any Lender may at any time grant to one or more banks, institutions or
other entities that regularly make, purchase or invest in bank loans (each a
"Participant") participating interests in its Commitments or any or all of its
Loans and Letter of Credit Liabilities. If a Lender grants any such
participating interest to a Participant, whether or not upon notice to the
Borrower and the Administrative Agent, such Lender shall remain responsible for
the performance of its obligations hereunder, and the Borrower and the
Administrative Agent shall continue to deal solely and directly with such Lender
in connection with such Lender's rights and obligations under this Agreement.
Any agreement pursuant to which any Lender may grant such a participating
interest shall provide that such Lender shall retain the sole right and
responsibility to enforce the obligations of the Borrower hereunder including,
without limitation, the right to approve any amendment, modification or waiver
of any provision of this Agreement; provided that such participation agreement
may provide that such Lender will not agree to any modification, amendment or
waiver of this Agreement described in clause (i) or (ii) of Section 9.05 without
the consent of the Participant. The Borrower agrees that, subject to Section
9.06(e), each Participant shall, to the extent provided in its participation
agreement, be entitled to the benefits of Section 2.15 and Article 8 with
respect to its participating interest. An assignment or other transfer which is
not permitted by Section 9.06(c) or 9.06(d)) below shall be given effect for
purposes of this Agreement only to the extent of a participating interest
granted in accordance with this subsection.

     (c)  Any Lender may at any time assign to one or more banks, other
institutions or other entities that regularly make, purchase or invest in bank
loans (each an "Assignee") all, or a proportionate part of all, of its
Commitment of any Class or its Loans and Letter of Credit Liabilities of any
Class and such Assignee shall assume such rights and obligations, pursuant to an
Assignment and Assumption Agreement substantially in the form of Exhibit D
hereto signed by such Assignee and such transferor Lender, with (and subject to)
the subscribed consent of the Borrower (which shall not be unreasonably withheld
or unreasonably delayed) and the Administrative Agent (and, in the case of a
Revolving Commitment, the Issuing Banks and the Swing Loan Lender); provided
that (i) after giving effect to any proposed assignment, (A) the Credit Exposure
of the transferor Lender (or in the case of a transferor Lender that is a fund,
the aggregate Credit Exposure of such Lender and its Related Funds) shall be
equal to (x) $0 or at least $5,000,000 if the transferor is a Revolving Lender
and (y) $0 or at least $1,000,000 if the transferor is a Term Lender and (B) the
amount of the Credit Exposure of the transferor Lender subject to such
assignment shall be at least equal to (x) $5,000,000 if the Assignee is a
Revolving Lender or (y) $1,000,000, if the Assignee is a Term Lender, unless in
either case the proposed Assignee is an affiliate of the transferor Lender, a
Related Fund of any Lender or was a Lender immediately before such assignment,
(ii) if a proposed Assignee is an affiliate of a transferor Lender, a Related
Fund of any Lender or was a Lender immediately before such assignment, no such
consent of

                                       91

<PAGE>

the Borrower or the Administrative Agent shall be required and (iii) if an Event
of Default shall have occurred and be continuing, no such consent of the
Borrower shall be required. When such instrument has been signed and delivered
by the parties thereto and recorded as provided in Section 2.14, and such
Assignee has paid to such transferor Lender the purchase price agreed between
them, such Assignee shall be a Lender party to this Agreement and shall have all
the rights and obligations of a Lender with a Commitment and/or Loans as set
forth in such instrument of assumption, and the transferor Lender shall be
released from its obligations hereunder to a corresponding extent, and no
further consent or action by any party shall be required. Upon the consummation
of any assignment pursuant to this subsection, the transferor Lender, the
Administrative Agent and the Borrower shall make appropriate arrangements so
that, if required, a new Note is issued to the Assignee. In connection with any
such assignment (other than an assignment to which any Agent or any affiliate of
any Agent is a party), the transferor Lender shall pay to the Administrative
Agent an administrative fee for processing such assignment in the amount of
$3,500; provided that only one such fee shall be due in respect of a
simultaneous assignment to more than one Related Fund. If the Assignee is not
incorporated under the laws of the United States or a State thereof, it shall
deliver to the Borrower and the Administrative Agent certification as to
exemption from deduction or withholding of taxes in accordance with Section
8.04(d).

     (d)  Any Lender may at any time assign all or any portion of its rights
under this Agreement and its Note to a Federal Reserve Bank, and any Lender that
is a fund that invests in bank loans may, with the consent of the Administrative
Agent, pledge all or any portion of its rights under this Agreement and its Note
to its trustee in support of its obligations to its trustee or its noteholders.
No such assignment or pledge shall release the transferor Lender from its
obligations hereunder.

     (e)  No Assignee, Participant or other transferee of any Lender's rights
shall be entitled to receive any greater payment under Section 8.03 or 8.04 than
such Lender would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.02, 8.03 or 8.04 requiring
such Lender to designate a different Applicable Lending Office under certain
circumstances.

     Section 9.07.  Designated Lenders. (a) Subject to the provisions of this
Section 9.07, any Lender may from time to time elect to designate an Eligible
Designee to provide all or a portion of the Loans to be made by such Lender
pursuant to this Agreement; provided that such designation shall not be
effective unless the Borrower and the Administrative Agent consent thereto. When
a Lender and its Eligible Designee shall have signed a designation agreement
substantially in the form of Exhibit E hereto and the Borrower and the
Administrative Agent shall have signed their respective consents thereto, such
Eligible Designee shall become a Designated Lender for purposes of this

                                    92

<PAGE>

Agreement. The Designating Lender shall thereafter have the right to permit such
Designated Lender to provide all or a portion of the loans to be made by such
Designating Lender pursuant to Section 2.01 and the making of such Loans or
portions thereof shall satisfy the obligation of the Designating Lender to the
same extent, and as if, such Loans or portion thereof were made by the
Designating Lender. As to any Loans or portion thereof made by it, each
Designated Lender shall have all the rights that a Lender making such Loans or
portion thereof would have had under this Agreement and otherwise; provided that
(x) its voting rights under this Agreement shall be exercised solely by its
Designating Lender and (y) its Designating Lender shall remain solely
responsible to the other parties hereto for the performance of its obligations
under this Agreement, including its obligations in respect of the Loans or
portion thereof made by it. No additional Note shall be required to evidence
Loans or portions thereof made by a Designated Lender; and the Designating
Lender shall be deemed to hold its Note as agent for its Designated Lender to
the extent of the Loans or portion thereof funded by such Designated Lender.
Each Designating Lender shall act as administrative agent for its Designated
Lender and give and receive notices and other communications on its behalf. Any
payments for the account of any Designated Lender shall be paid to its
Designating Lender as administrative agent for such Designated Lender and
neither the Borrower nor the Administrative Agent shall be responsible for any
Designating Lender's application of such payments. In addition, any Designated
Lender may (i) with notice to, but without the prior written consent of, the
Borrower or the Administrative Agent, assign all or portions of its interest in
any Loans to its Designating Lender or to any financial institutions consented
to by the Borrower and the Administrative Agent providing liquidity and/or
credit facilities to or for the account of such Designated Lender to support the
funding of Loans or portions thereof made by such Designated Lender and (ii)
disclose on a confidential basis any non-public information relating to its
Loans or portions thereof to any rating agency, commercial paper dealer or
provider of any guarantee, surety, credit or liquidity enhancement to such
Designated Lender.

     (b)  Each party to this Agreement agrees that it will not institute
against, or join any other Person in instituting against, any Designated Lender
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceeding or other proceeding under any federal or state bankruptcy or similar
law, for one year and a day after all outstanding senior indebtedness of such
Designated Lender is paid in full. The Designating Lender for each Designated
Lender agrees to indemnify, save, and hold harmless each other party hereto for
any loss, cost, damage and expense arising out of its inability to institute any
such proceeding against such Designated Lender. This Section 9.07(b) shall
survive the termination of this Agreement.

     Section 9.08.  No Reliance on Margin Stock. Each of the Lenders represents
to each Agent and each of the other Lenders that it in good faith is not

                                       93

<PAGE>

relying upon any Margin Stock as collateral in the extension or maintenance of
the credit provided for in this Agreement.

     Section 9.09.  Governing Law; Submission to Jurisdiction. This Agreement
and each Note shall be governed by, and construed and interpreted in accordance
with, the laws of the State of New York. To the extent permitted by applicable
law, the Borrower hereby submits to the nonexclusive jurisdiction of the United
States District Court for the Southern District of New York and of any New York
State court sitting in New York City for purposes of all legal proceedings
arising out of or relating to this Agreement or the transactions contemplated
hereby. The Borrower irrevocably waives, to the fullest extent permitted by law,
any objection which it may now or hereafter have to the laying of the venue of
any such proceeding brought in such a court and any claim that any such
proceeding brought in such a court has been brought in an inconvenient forum.

     Section 9.10.  Counterparts; Effectiveness. This Agreement may be signed in
any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement shall become effective on the date that the Administrative Agent
shall have received counterparts hereof signed by each of the parties hereto
(or, in the case of any party as to which an executed counterpart shall not have
been received, receipt by the Administrative Agent in the form satisfactory to
it of facsimile or other written confirmation from such party of execution of a
counterpart hereof by such party).

     Section 9.11.  WAIVER OF JURY TRIAL. TO THE EXTENT PERMITTED BY APPLICABLE
LAW, EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

     Section 9.12.  ERISA Matters. (a) Representations and Warranties. Each
Lender, solely with respect to itself, severally represents and warrants that
one or more of the following is true with respect to all of the funds used to
make or purchase any interest in any Loan or Letter of Credit Liability (or one

     investment fund," as defined in Section IV of Prohibited Transaction Class
     Exemption 91-38 issued by the U.S. Department of Labor, in which an ERISA
     Plan has an interest, and (B) such Loan or Letter of Credit Liability or

     agreement related thereto shall at all times thereafter be, entitled to
     full relief under Prohibited Transaction Class Exemption 90-1 or 91-38, as

     defined in Section V of Prohibited Transaction Class Exemption 95-60 issued
     by the U.S. Department of Labor, and such Loan or Letter of Credit
     Liability or interest therein is, and shall at all times thereafter satisfy
     the requirements to be and shall be, exempt under Prohibited Transaction
     Class Exemption 95-60 to the fullest extent provided therein.

     (b)  Representations of Transferees. Each Person that becomes an Assignee
or Participant hereunder shall be deemed to make, effective upon the acceptance
of any assignment of an interest hereunder or the entering into of any
participation agreement contemplated in Section 9.06(b), the representations and
warranties set forth in Section 9.12. Such deemed representation shall be

ERISA Plan (i) represents and warrants that it has evaluated for itself the
merits of making or maintaining such Loan or Letter of Credit Liability; has not

<PAGE>

any evaluation or other investment advice on any basis in respect of the
advisability of making or maintaining such Loan or Letter of Credit Liability;
and is not relying and has not relied on the Borrower or any of its Affiliates
for any investment advice with respect to making or maintaining such Loan or
Letter of Credit Liability in any manner that would cause the Borrower or any of

a "disqualified person" (within the meaning of the Internal Revenue Code) in
connection with making or maintaining such Loan or Letter of Credit Liability
and (ii)acknowledges and confirms that none of the Borrower or any of its
Affiliates is acting as a "fiduciary" (within the meaning of ERISA, the Internal
Revenue Code or any other applicable law or any rulings or regulations
thereunder) for such Lender in connection with making or maintaining such Loan
or Letter of Credit Liability.

     Section 9.13.  Confidentiality. Each Lender and Agent agrees to hold all
non-public information obtained pursuant to the requirements of this Agreement
in accordance with its customary procedure for handling confidential information
of this nature and in accordance with safe and sound commercial lending

disclosing such information (i) to any affiliate of such Lender or to any other
Lender or Agent, (ii) to any other Person if reasonably incidental to the
administration of the Loans and Letter of Credit Liabilities, (iii) to the
extent required by applicable laws or regulations or upon the order of any court
or administrative agency, (iv) upon the request or demand of any regulatory

         (xiii)     the form of Note attached as Exhibit A to the Credit
                    Agreement.

Items (i) through (xiii) are hereafter sometimes referred to each as a "Loan
Document," and collectively, the "Loan Documents". The Amended Pledge
Agreements, the Amended Security Agreements and the Amended Texas Mortgages are
collectively referred to herein as the "Amended Collateral Documents". In
addition, we have examined the UCC financing statements (copies of which are
attached hereto, together with the UCC financing statements referred to therein,
the "Financing Statements") executed, respectively, by the Company, LCW and the
JV Subsidiaries (other than Lyondell Petrochemical L.P. Inc.) prior to the date
hereof and filed prior to the date hereof, certificates of representatives of
the Loan Parties and other documents as the basis for our opinions hereinafter
set forth.

          On the basis of the foregoing, and subject to the assumptions,
qualifications and limitations set forth below, we are of the opinion that:

          1.   The Credit Agreement constitutes the legal, valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms. Each Note, when properly completed and executed and delivered by the
Company, will constitute the legal, valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms. Each of the
Subsidiary Guarantees and the Amended Collateral Documents, other than the
Louisiana Mortgage, constitutes the legal, valid and binding obligation of each
Loan Party that is a party thereto, enforceable against that Loan Party in
accordance with its terms.

          2.   The execution, delivery and performance by the Loan Parties of
the respective Loan Documents (other than the Amended Mortgages) to which they
are party do not (a) violate any applicable federal or New York law or (b)
require as a condition precedent thereto consent or approval of, registration or
filing with, or any other action by, any governmental authority, except for the
filing and recordation of the Amended Mortgages and of UCC financing statements
pursuant to the Loan Documents. The execution, delivery and performance of the
Amended Texas Mortgages by the Company do not (a) violate any applicable federal
or Texas law or (b) require as a condition precedent thereto consent or approval
of, registration or filing with, or any other action by, any governmental
authority, except for the filing and recordation of the Amended Texas Mortgages
and of UCC financing statements pursuant to the Amended Texas Mortgages. The
execution, delivery and performance by the Company of the Amended Louisiana
Mortgage do not (a) violate any applicable federal law or (b) require as a
condition precedent thereto consent or approval of, registration or filing with,
or any other action by, any federal governmental authority.

                                       B-4

<PAGE>

          3.   No Loan Party is (a) an "investment company" within the meaning
of the Investment Company Act of 1940, as amended, (b) a "holding company" or a
"subsidiary company" as defined in the Public Utility Holding Company Act of
1935, as amended, or (c) otherwise subject to any statute or regulation (other
than Regulations U and X of the Board of Governors of the Federal Reserve
System) that restricts its ability to incur Debt under the Credit Agreement.

          4.   The making of Loans and the application of the proceeds thereof
as provided for in the Credit Agreement do not violate Regulation U or X of the
Board of Governors of the Federal Reserve System.

          5.   The Amended Security Agreements create valid security interests
in favor of the Administrative Agent for the benefit of the "Secured Parties,"
as defined and to the extent provided therein, in all right, title and interest
of the respective Loan Parties that are party thereto in that portion of the
"Collateral" (as defined in the Amended Security Agreements) in which a security
interest may be created under Article 9 of the Uniform Commercial Code in effect
in the State of New York (the "New York Code"). Except as otherwise provided by
Sections 9-303 through 9-306 of the New York Code, the perfection of such
security interests will, pursuant to Section 9-301 of the New York Code, be
determined under the local laws of the jurisdiction in which the debtor is
located (which is the State of Delaware for each Loan Party), and assuming that
Chapter 9 of the Uniform Commercial Code of the State of Delaware ("Delaware
Code") governs the perfection of a security interest in personal property and
that the Delaware Code is identical to the New York Code, as a result of the
filing of the applicable Financing Statements executed by those respective Loan
Parties, the Administrative Agent has a perfected security interest within the
meaning of the Delaware Code in that portion of the Collateral and in the
proceeds thereof in which a security interest may be created under Article 9 of
the New York Code and perfected by so filing the Financing Statements, subject,
however, with respect to proceeds, to Section 9-315 of the New York Code and any
comparable provisions of the Delaware Code.

          6.   Each Amended Pledge Agreement creates a valid security interest
in favor of the Administrative Agent for the benefit of the "Secured Parties,"
as defined and to the extent provided therein, in all right, title and interest
of the Company in the Subsidiary Shares (as such term is defined in those pledge
agreements other than the LLC Pledge Agreement), in the Subsidiary Interest (as
defined in the LLC Pledge Agreement) and in that portion of the Collateral (as
defined in those pledge agreements) and the proceeds thereof to the extent a
security interest may be created under the New York Code. As a result of the
filing of the applicable Financing Statements executed by the Company, the
Administrative Agent has a perfected security interest within the meaning of
Chapter 9 of the New York Code in the Subsidiary Interest and such Collateral
and in those proceeds to the extent such security interest therein may be
perfected by so filing, subject, however, with respect to proceeds, to Section
9-315 of the

                                       B-5

<PAGE>

New York Code and any comparable provisions of the Delaware Code. Assuming (a)
delivery in New York on or prior to this date to, and continued possession and
control (within the meaning of Section 8-106 of the New York Code) in New York
by, the Administrative Agent of the stock certificates representing the issued
and outstanding Subsidiary Shares, together with stock powers properly executed
in blank with respect thereto, and (b) the Administrative Agent acquired its
interest in those Subsidiary Shares in good faith and without notice of any
adverse claims (as such term is defined in Section 8-103 of the New York Code),
the Administrative Agent has a perfected security interest in those Subsidiary
Shares within the meaning of Article 9 of the New York Code, free of adverse
claims to the extent provided by Articles 8 and 9 of the New York Code.

          7.   Each Amended Texas Mortgage creates a valid lien in favor of the
Administrative Agent for the benefit of the "Secured Parties," as defined and to
the extent provided therein, in all right, title and interest of the Company in
such of the "Mortgaged Property" described therein as constitutes real property
under the law of the State of Texas (the "Real Property"). The proper recordings
of the Amended Texas Mortgages in the real property records of the County Clerk
of Harris County, Texas are the only filings, recordings and registrations
necessary to publish notice and preserve the liens of the Amended Texas
Mortgages in the Real Property. Each Amended Texas Mortgage creates a valid
security interest in favor of the Administrative Agent for the benefit of such
Secured Parties to the extent provided therein in all right, title and interest
of the Company in that portion of the "Mortgaged Property" (other than the Real
Property) in which a security interest may be created under Chapter 9 of the
Texas Code (the "Texas UCC Collateral"). As a result of the filing of the
applicable Financing Statements, the Administrative Agent has a perfected
security interest within the meaning of the Texas Code in that portion of the
Texas UCC Collateral which may be perfected by so filing such Financing
Statements and in the proceeds thereof in which a security interest may be
created under Chapter 9 of the Texas Code and perfected by so filing those
Financing Statements, subject, however, with respect to proceeds, to Section
9.315 of the Texas Code.

          8.   No mortgage tax, documentary stamp tax, recording tax, transfer
tax or similar tax or charge is payable by the Administrative Agent to the State
of Texas or any governmental agency thereof on account of the Liens created by
the Amended Collateral Documents or the filing, recording or registration of the
Texas Mortgages or the Financing Statements, except for nominal filing or
recording fees.

          9.   The security interests created by the Amended Collateral
Documents secure all future Loans and Reimbursement Obligations of the Company
in respect of the Letters of Credit and, insofar as the priority of those
security interests is governed by the New York Code, the Delaware Code, the
Texas Code and the Texas Property Code, have the same priority (subject to
Section 9.307 of

                                       B-6

<PAGE>

the New York Code and by comparable provisions of the Texas Code and Delaware
Code) with respect to those future extensions of credit as they have with
respect to the Loans made on the date hereof, except (a) to the extent that any
priority may be affected by any Lien imposed by law in favor of any government
or governmental authority or agency and (b) as to after acquired property that
is covered by those documents, Liens to which such property is subject at the
time of acquisition by the applicable Loan Party.

          10.  If all material facts and issues of law were presented and
properly argued, a Texas court, or a federal court sitting in the State of
Texas, should give effect to the governing law provisions of the Loan Documents,
subject to Section 35.51(f)(4) of the Texas Code.

          11.  The execution, delivery and performance by the Loan Parties of
the Loan Documents to which they are party do not constitute a default under the
ARCO Chemical Indenture.

          The foregoing opinions are subject to the following assumptions,
qualifications and limitations:

               (A) We have, without independent verification, relied on
          certificates of representatives of the Loan Parties and the
          representations and warranties of the Loan Parties contained in the
          Loan Documents with respect to the accuracy of the factual matters
          contained therein and assumed with your approval (i) that each party
          to the Loan Documents has the power and authority to enter into those
          Loan Documents and to perform its obligations thereunder, (ii) the due
          authorization, execution and delivery of the Loan Documents by each
          party thereto, including such authorization, execution and delivery of
          the Credit Agreement by the requisite number of Lenders, (iii) that
          the Loan Documents constitute the legal, valid, binding and
          enforceable obligation of each party thereto (other than the Loan
          Parties) and (iv) the genuineness of all signatures, the conformity to
          authentic, original documents of all documents submitted to us as
          certified or photostatic copies and the authenticity of all documents
          submitted to us as originals.

               (B) Our opinions set forth in paragraphs 1 through 9 are subject
          to the effect of (i) applicable bankruptcy, insolvency,
          reorganization, fraudulent transfer or conveyance, moratorium,
          conservatorship and similar laws affecting creditor's rights and
          remedies generally, (ii) general principles of equity (whether
          considered in a proceeding in equity or at law), (iii) principles of
          materiality and reasonableness and implied covenants of good faith and
          fair dealing and (iv) the rights of the United States under the
          Federal Tax Lien Act of 1966, as amended. Additionally, the validity
          and enforceability of certain of the remedial and waiver provisions of
          the Amended Collateral Documents may be limited by

                                       B-7

<PAGE>

          applicable laws and judicial interpretations, but, in our opinion and
          subject to the other qualifications and limitations set forth herein
          and the economic consequences of any delay in the enforcement of the
          remedies provided for in the Loan Documents, those limitations should
          not substantially interfere with (i) the judicial enforcement of the
          obligation of the Company to repay the Loans and the interest accrued
          thereon (to the extent not deemed a penalty), as provided in the
          Credit Agreement, subject to Sections 51.003, 51.004 and 51.005 of the
          Texas Property Code, (ii) the acceleration of the obligation of the
          Company to repay the Loans, together with such interest, upon an Event
          of Default arising from the failure to pay such obligations when due
          or upon the failure to perform any other material provision of the
          Loan Documents to be performed by it or any other Loan Party and (iii)
          the judicial foreclosure or, if the Collateral Agent elects to
          exercise the power or right of sale as specified in the Amended
          Collateral Documents, the non-judicial foreclosure of the Liens
          created by the Amended Collateral Documents, and the sale of the
          personal property Collateral, at maturity or upon an acceleration
          described in clause (ii) immediately above in accordance with
          applicable law and the Loan Documents. Further to the foregoing, the
          provisions of the Loan Documents regarding the rights and remedies
          available to the Secured Parties after the occurrence of a Default or
          Event of Default are subject to procedural requirements that are not
          necessarily reflected in the Loan Documents which may affect or
          restrict the rights and remedies so stated to be available thereunder.
          We express no opinion as to whether a court would grant specific
          performance or any other equitable remedy or any particular remedy or
          the enforceability of any self-help remedy

               (C) With respect to our opinion in paragraph 3, we assume that
          the Loan Parties own no assets and conduct no business other than as
          described in the Company's Annual Report on Form 10-K for fiscal year
          2001.

               (D) We call to your attention that Section 552 of the United
          States Bankruptcy Code limits the extent to which proceeds realized
          and property acquired by a debtor after the commencement of a case
          thereunder may be subject to a security interest arising from a
          security agreement entered into by the debtor before the commencement
          of that case.

               (E) No opinion is expressed above as to the enforceability of
          Section 9.02 or 9.04 of the Credit Agreement or provisions of similar
          import contained in any other Loan Document or any provision of the
          Loan Documents that purports to (i) waive rights of any party that
          cannot be waived as a matter of applicable law, (ii) entitle a party
          to indemnification or absolution from liability in respect of any
          matters arising under any securities laws or in whole or in part by
          reason of any

                                       B-8

<PAGE>

          illegal, wrongful or grossly negligent act or omission of that party,
          (iii) prohibit any unwritten waivers of or amendments to any
          provisions of the Loan Documents, (iv) establish any evidentiary
          standard, (v) restrict access to legal or equitable remedies or (vi)
          grant remedies exercisable when no Default or Event of Default exists.

               (F) We express no opinion as to (i) the enforceability of
          provisions relating to delay or omission of enforcement of rights or
          remedies, marshaling of assets, rights of third parties or
          prohibitions against transfer, alienation or hypothecation of
          property, (ii) the enforceability of a present assignment of assets or
          rental income from the Mortgaged Property without first requiring the
          Collateral Agent to obtain lawful possession of the Mortgaged Property
          after the occurrence of an Event of Default under the Loan Documents,
          (iii) any right to exclude a Loan Party from possession of the
          Mortgaged Property prior to the time lawful possession is obtained
          through foreclosure proceedings or other lawful means, (iv) the
          enforceability of provisions appointing a Person as attorney-in-fact
          for another Person, (v) whether a court would construe a yield
          maintenance payment due as a penalty which is not enforceable or
          collectible, (vi) the enforceability of provisions which leave any
          provision to subsequent agreement or (vii) the enforceability of any
          provisions that provide for certain acts or matters to be null and
          void automatically or ab initio.

               (G) No opinion is expressed above as to (i) the effect of any
          state or federal securities laws or regulations insofar as they are
          applicable to or otherwise affect any party to any Loan Document, the
          transactions contemplated by the Loan Documents or the exercise of any
          rights or remedies of any party to the Loan Documents or (ii) various
          state and federal laws and regulations applicable to banks, insurance
          companies or other financial institutions or the business or lending
          transactions of the Administrative Agent, the Agents or the Lenders or
          any assignee or participant of any such Person which may relate to the
          Loan Documents or the transactions contemplated thereby.

               (H) We express no opinion as to the priority of any Liens created
          by the Amended Collateral Documents, except to the extent set forth in
          paragraph 6. We have assumed, with your approval and without
          independent verification, that (i) the Financing Statements set forth
          the correct name and address of the Administrative Agent and (ii) the
          Loan Parties party to the Amended Collateral Documents have rights in
          the Collateral. We have assumed that (i) the descriptions of the
          previously filed Financing Statements referred to in the attached
          Financing Statements accurately identify the office(s) in which such
          financing statements were filed, the dates of filing and file numbers
          and the most recent continuation and amendment statements filed with
          respect thereto,

                                       B-9

<PAGE>

          (ii) the attached Financing Statements and such previously filed
          Financing Statements referred to therein, and any applicable
          continuation and amendment statements, are in fact properly filed in
          such filing offices, and (iii) the previously filed Financing
          Statements purportedly filed in filing offices other than in the State
          of Texas perfected the UCC Collateral under applicable law. We express
          no opinion as to (i) the value of, the accuracy or completeness of any
          description of, or the location or characterization of, any personal
          property Collateral or the value of, the location or characterization
          of, or the accuracy, completeness or sufficiency of any description
          of, the Real Property, including for purposes of notice or conveyance,
          (ii) the physical condition or actual use made of any Collateral and
          (iii) whether any Collateral is in compliance with any laws or
          regulations relating to the construction, occupancy or use thereof,
          including zoning laws, building codes and environmental laws.

               (I) We express no opinion with respect to any Collateral which is
          or may become fixtures (except as paragraph 7 sets forth),
          as-extracted collateral, equipment used in farming operations, farm
          products, accounts or general intangibles arising from or relating to
          the sale of farm products by a farmer, consumer goods, crops growing
          or to be grown, timber to be cut, minerals or the like (including oil
          and gas) or accounts resulting from the sale of minerals at the
          wellhead or minehead.

               (J) We call to your attention that (i) assuming the Delaware Code
          is identical to the New York Code to such matter, the Delaware Code
          requires the filing of UCC continuation statements, executed by the
          secured party of record, within the period of six months prior to the
          expiration of each period of five years from the respective dates of
          the original filings of UCC financing statements in order to maintain
          the effectiveness of such filings, (ii) changes in the name, identity
          or corporate structure or the location (within the meaning of Section
          9-307 of the New York Code and by comparable provisions of the
          Delaware Code) of the Loan Parties may cause the security interests of
          the Collateral Agent purported to be created by the Amended Collateral
          Documents to be unperfected unless new, appropriate UCC financing
          statements are properly filed in the appropriate jurisdictions.

               (K) Our opinion in paragraph 11 is not free from doubt. The ARCO
          Chemical Indenture does not define the phrase "equally and ratably"
          contained in Section 5.03 thereof, and we are not aware of any case in
          which a court has considered whether arrangements of the sort provided
          for in the Collateral Documents conflict with a covenant such as
          Section 5.03. Consequently, a court considering those arrangements

                            Lyondell Chemical Company

<PAGE>

(each a "Loan Document," and collectively, the "Loan Documents"). The Amended
Pledge Agreements, the Amended Security Agreements and the Amended Mortgages are
collectively referred to herein as the "Amended Collateral Documents".

     Based upon the foregoing, subject to the qualifications, limitations,
exceptions and assumptions hereinafter set forth, and having due regard for such
legal considerations as I deem relevant, I am of the opinion that:

          1.   Each of the Loan Parties (other than LCW, ARCO LP, LRLP and
POLP), is a corporation duly incorporated and validly existing in good standing
under the laws of the State of Delaware and has the corporate power and
authority to own, lease and operate its properties and to conduct its business
as presently conducted. POLP is a limited partnership duly formed and validly
existing in good standing under the laws of the State of Delaware and has the
requisite partnership power and authority to own, lease and operate its
properties and to conduct its business as presently conducted. ARCO LP is a
limited partnership duly formed and validly existing in good standing under the
laws of the State of Delaware and has the requisite partnership power and
authority to own, lease and operate its properties and to conduct its business
as presently conducted. LRLP is a limited liability company duly formed and
validly existing in good standing under the laws of the State of Delaware and
has the requisite limited liability company power and authority to own, lease
and operate its properties and to conduct its business as presently conducted.
Except where the failure to do so, individually or in the aggregate, would not
reasonably be expected to result in a Material Adverse Effect, each Loan Party
(other than LCW) is qualified, licensed or registered to do business in, and is
in good standing in, every jurisdiction where such qualification, licensing and
registration is required.

          2.   Each Loan Party has (and in the case of LCW, had) the requisite
corporate, limited liability company or partnership power and authority to
execute and deliver the Loan Documents to which it is a party and to perform its
obligations thereunder. The execution, delivery and performance by each Loan
Party of the Loan Documents to which it is a party have been duly authorized by
all necessary corporate or limited liability company or limited partnership
proceedings of that Loan Party.

          3.   The execution, delivery and performance by each Loan Party of the
Loan Documents to which it is a party do not (a) contravene its certificate of
incorporation, by-laws, regulations or limited partnership agreement, as the
case may be, as amended to date, (b) except as qualified below, constitute a
default under any agreement or instrument governing Material Debt of any Loan
Party, (c) breach or otherwise violate any other material agreement of any Loan
Party or any judgment, order or decree of any governmental authority known to me
that is binding on any Loan Party or any of its assets or (d) except for the
Amended Collateral Documents, the Senior Secured Note Indentures, the ARCO
Chemical

                                       C-4

<PAGE>

Indenture (as defined in the Amended Collateral Documents) and the PBGC
Settlement Agreement, result in the creation or imposition of any Lien on any
material properties or assets of any Loan Party. My opinion in clause (c) with
respect to the ARCO Chemical Indenture is not free from doubt. The ARCO Chemical
Indenture does not define the phrase "equally and ratably" contained in Section
5.03 thereof, and I am not aware of any case in which a court has considered
whether arrangements of the sort provided for in the Amended Collateral
Documents conflict with a covenant such as Section 5.03. Consequently, a court
considering those arrangements might reach a conclusion different from mine.

          4.   To my knowledge, there are no actions, suits or proceedings by or
before any court or arbitrator or any governmental body, agency or official that
are pending or threatened against or affecting any Loan Party or the respective
businesses, assets or rights of any Loan Party as to which there is a reasonable
possibility of an adverse determination and that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect.

          This opinion is limited to applicable Texas law, federal law, the
General Corporation Law of the State of Delaware, the Delaware Limited Liability
Company Act and the Delaware Revised Uniform Limited Partnership Act, each as in
effect on the date hereof, and no opinion is expressed herein as to the laws of
any other jurisdiction. I undertake no obligation or responsibility to update or
supplement this opinion in response to subsequent changes in law or future
events affecting any of the transactions contemplated by any Loan Document. This
opinion is rendered solely for your benefit in connection with the transactions
contemplated by the Credit Agreement to be consummated on this date. Except for
the use permitted herein, this letter is not to be quoted or reproduced in whole
or in part or otherwise referred to in any manner, nor is it to be filed with
any governmental agency or delivered to any other person without my prior
written consent. This opinion may not be used for any other purpose or relied on
by any other Person without, in each instance, my prior written consent.

                                                    Very truly yours,

                                                    Gerald A. O'Brien
                                                    Deputy General Counsel

                      dated as of ________________, 20____

     Reference is made to the Amended and Restated Credit Agreement dated as of

agree as follows:

      5.  The Designator designates the Designee as its Designated Lender under
