                    CREDIT AGREEMENT dated as of November 25, 1997, among
               EQUISTAR CHEMICALS, LP, a Delaware limited partnership;
               MILLENNIUM AMERICA INC., a Delaware corporation, as Guarantor;
               the lenders from time to time party hereto, initially consisting
               of those listed on Schedule 2.01 hereto; BANK OF AMERICA NATIONAL
               TRUST AND SAVINGS ASSOCIATION ("BofA"), as Servicing Agent and
               Documentation Agent; THE CHASE MANHATTAN BANK ("Chase"), as
               Syndication Agent; and BofA and Chase as administrative agents
               (in such capacity, the "Administrative Agents").


          The Borrower (such term and each other capitalized term used but not
otherwise defined herein having the meaning assigned to it in Article I) has
requested the Lenders to extend credit in order to enable it to borrow on a
revolving basis an aggregate principal amount not in excess of $1,250,000,000.
The proceeds of such Borrowings are to be used to finance a $750,000,000 payment
to Millennium at the closing of the Joint Venture, to provide working capital
availability (including the financing of $250,000,000 required by the Borrower
as a result of retention of certain accounts receivable by Millennium
Petrochemicals Inc.) and for general partnership purposes, including non-hostile
acquisitions and capital expenditures.  The Lenders are willing to extend such
credit to the Borrower on the terms and subject to the conditions set forth
herein.

          Accordingly, in consideration of the mutual agreements herein
contained and other good and valuable consideration, the sufficiency and receipt
of which are hereby acknowledged, the parties hereto hereby agree as follows:


                                   ARTICLE I

                                  Definitions

          SECTION 1.01.  Definitions.  As used in this Agreement, the following
terms shall have the meanings specified below:

          "ABR Borrowing" shall mean a Borrowing comprised of ABR Loans.

          "ABR Loan" shall mean any Revolving Loan bearing interest at a rate
determined by reference to the Alternate Base Rate in accordance with Article
II.

 
                                                                               2


          "Acceptable Subordinated Loan" shall mean any loan to the Borrower
from a Partner or an Affiliate of a Partner (other than the Borrower or a
Subsidiary), but only to the extent that (a) such loan does not mature, and no
payment, prepayment, redemption or repurchase of the principal amount thereof is
required by the terms thereof, prior to the Maturity Date and (b) such loan is
subordinated to the Obligations on terms acceptable to the Administrative
Agents.

          "Administrative Fees" shall have the meaning assigned to such term in
Section 2.08(c).

          "Affiliate" shall mean, with respect to any person, any other person
which directly or indirectly controls, is under common control with or is
controlled by such person.  As used in this definition, "control" (including,
with correlative meanings, "controlled by" and "under common control with")
shall mean possession, directly or indirectly, of power to direct or cause the
direction of management or policies (whether through ownership of securities or
partnership or other ownership interests, by contract or otherwise).

          "Alternate Base Rate" shall mean, for any day, a rate per annum
(rounded upwards to the next higher 1/16th of 1%) equal to the greater of (a)
the Reference Rate in effect on such day and (b) the Federal Funds Effective
Rate in effect on such day plus 1/2 of 1%.  If for any reason the Servicing
Agent shall have determined (which determination shall be conclusive absent
manifest error) that it is unable to ascertain the Federal Funds Effective Rate
for any reason, including, without limitation, the inability of the Servicing
Agent to obtain sufficient bids in accordance with the terms hereof, the
Alternate Base Rate shall be determined without regard to clause (b) of the
first sentence of this definition until the circumstances giving rise to such
inability no longer exist.

          "Applicable Lending Office" shall mean, with respect to each Lender,
(i) such Lender's domestic lending office in the case of an ABR Loan, a NIBOR
Loan or a Fixed Rate Loan or (ii) such Lender's LIBOR Lending Office in the case
of a LIBOR Loan.

          "Applicable Percentage" shall mean, for any day, with respect to any
LIBOR Loan (other than any Competitive Loan) or NIBOR Loan, or with respect to
the Facility Fee, as the case may be, the applicable percentage set forth below
under the caption 

 
                                                                               3

"LIBOR/NIBOR Spread" or "Facility Fee Percentage", as the case may be, based
upon the Index Ratings:

                                                 Facility    
           Index               LIBOR/NIBOR          Fee    
          Ratings                 Spread        Percentage  
          -------                 ------        -----------

     BBB+/Baa1
- ---------------------------------------------------------------------- 
Category 3                            .275%         .125%
     BBB/Baa2
- ---------------------------------------------------------------------- 
Category 4                            .350%         .150%
     BBB-/Baa3
- ---------------------------------------------------------------------- 
Category 5                            .450%         .200%
     BB+/Ba1
- ----------------------------------------------------------------------
Category 6                            .500%         .250%
     BB/Ba2 or lower
- ----------------------------------------------------------------------

          For purposes of the foregoing, (i) if either Moody's or S&P shall not
have in effect an Index Rating (other than by reason of the circumstances
referred to in the last sentence of this definition), then such rating agency
shall be deemed to have established an Index Rating in Category 6; (ii) if the
Index Ratings established or deemed to have been established by Moody's and S&P
shall fall within adjacent Categories, the Applicable Percentage shall be based
on the higher of the two ratings; provided, that if the ratings established or
deemed to have been established by Moody's and S&P differ by two or more
Categories, the Applicable Percentage shall be based on the Category next below
that in which the higher rating falls; and (iii) if the Index Ratings
established or deemed to have been established by Moody's and S&P shall be
changed (other than as a result of a change in the rating system of Moody's or
S&P), such change shall be effective as of the date on which it is first
announced by the applicable rating agency.  Each change in the Applicable
Percentage shall apply during the period commencing on the effective date of
such change and ending on the date immediately preceding the effective date of
the next such change.  If the rating system of Moody's or S&P shall change, or
if either such rating agency shall cease to be in the business of rating
corporate debt obligations, the Borrower and the Administrative Agents shall
negotiate in good faith to amend this definition to reflect such changed rating
system or the non-availability of ratings from such rating agency and, pending
the effectiveness of any such amendment, the Applicable Percentage shall be
determined by reference to the Index Rating of such rating agency most 

 
                                                                               4

recently in effect prior to such change or cessation. Notwithstanding any other
provision of this definition, if the Index Ratings at any time in effect shall
be the ratings applicable to the Assumed Lyondell Debt and the Administrative
Agents or the Required Lenders shall notify the Borrower that, in their good
faith judgment, the Index Ratings are affected by the status of Lyondell as an
obligor on the Assumed Lyondell Debt in such a manner that they do not fairly
represent the Borrower's creditworthiness, the Borrower shall within 180 days
either (i) obtain from S&P and Moody's ratings or indicative ratings of the sort
referred to in clauses (a) and (b) of the definition of "Index Ratings" or (ii)
agree with the Lenders on amendments to the definition of "Applicable
Percentage" that in the judgment of the Borrower and the Lenders are appropriate
to reflect the creditworthiness of the Borrower (which agreement will be set
forth in an amendment to this Agreement). Pending the obtaining of such ratings
or indicative ratings or such agreement, the Applicable Percentage will be
determined by reference to the Index Ratings in effect on the 60th day prior to
the giving of such notice by the Administrative Agents or the Required Lenders.

          "Asset Contribution Agreements" shall mean (i) the Asset Contribution
Agreement between Lyondell, Lyondell LP and the Borrower and (ii) the Asset
Contribution Agreement between Millennium Petrochemicals Inc., Millennium LP and
the Borrower, each dated as of the Effective Date and as amended, supplemented
or otherwise modified from time to time.

          "Assignment and Acceptance" shall mean an assignment and acceptance
entered into by a Lender and an assignee, in the form of Exhibit A.

          "Assumed Lyondell Debt" shall mean outstanding Indebtedness of
Lyondell in an aggregate principal amount of $745,000,000 outstanding under the
Lyondell Indentures and to be assumed by the Borrower.

          "Availability Period" shall mean the period from and including the
Effective Date to but excluding the earlier of the Maturity Date and the date of
termination of the Commitments.

          "Board" shall mean the Board of Governors of the Federal Reserve
System of the United States.

          "Borrower"  shall mean Equistar Chemicals, LP, a Delaware limited
partnership.

          "Borrowing" shall mean (a) a Loan or group of Loans of a single Type
made by the Lenders on a single date and as to which a single Interest Period is
in effect, (b) a Competitive Loan or group of Competitive Loans made by the
Lender or Lenders whose 

 
                                                                               5

Competitive Bids have been accepted pursuant to Section 2.03 and made on a
single date and as to which a single Interest Period is in effect or (c) a
Swingline Loan.

          "Business Day" shall mean any day which is not a Saturday, Sunday or
legal holiday in the State of New York or the State of Texas on which banks are
open for business in New York City and Houston; provided, however, that (i) when
used in connection with a LIBOR Loan, the term "Business Day" shall also exclude
any day on which banks are not open for dealings in deposits in Dollars in the
London interbank market and (ii) when used in connection with a NIBOR Loan, the
term "Business Day" shall also exclude any day on which the lending offices of
the Lender that is the Servicing Agent where its Eurodollar funding operations
are customarily conducted are closed.

          "Capitalized Lease Obligations" of any person shall mean obligations

          SECTION 2.01.  Commitments.  (a)  Subject to the terms and conditions
and relying upon the representations and warranties herein set forth, each
Lender agrees, severally and not jointly, to make Revolving Loans to the
Borrower from time to time during the Availability Period.

          (b)  Notwithstanding anything to the contrary contained in this
Agreement, in no event may Loans be borrowed under this Article II if, after
giving effect thereto (and to any concurrent repayment or prepayment of Loans
and/or LC Disbursements), (i) the aggregate Revolving Credit Exposures plus the
aggregate principal amount of outstanding Competitive Loans would exceed the
Total Commitment.

          (c)  Within the foregoing limits, the Borrower may borrow, pay or
prepay and reborrow Revolving Loans hereunder during the Availability Period and
subject to the terms, conditions and limitations set forth herein.

          SECTION 2.02.  Loans.  (a)  Each Revolving Loan shall be made as part
of a Borrowing consisting of Revolving Loans made ratably by the Lenders in
accordance with their respective Commitments; provided, however, that the
failure of any Lender to make any Revolving Loan shall not in itself relieve any
other Lender of its obligation to lend hereunder (it being understood, however,
that no Lender shall be responsible for the failure of 

 
                                                                              23

any other Lender to make any Revolving Loan to be made by such other Lender).
Each Competitive Loan shall be made in accordance with the procedures set forth
in Section 2.03. The Loans comprising any Borrowing shall be (i) in the case of
Competitive Loans, in an aggregate principal amount which is not less than
$25,000,000, (ii) in the case of Revolving Loans (other than ABR Loans), in an
aggregate principal amount which is an integral multiple of $1,000,000 and not
less than the lesser of $5,000,000 and the remaining aggregate balance of the
Commitments and (iii) in the case of ABR Loans, in an aggregate principal amount
which is an integral multiple of $1,000,000.

          (b)  Each Competitive Borrowing shall be comprised entirely of LIBOR
Competitive Loans or Fixed Rate Loans and each Revolving Borrowing shall be
comprised entirely of LIBOR Revolving Loans, NIBOR Loans or ABR Loans, as the
Borrower may request pursuant to Section 2.03 or Section 2.04, as applicable.
Each Lender may at its option make any LIBOR Loan or NIBOR Loan by causing any
branch or Affiliate of such Lender to make such Loan; provided, however, that
any exercise of such option shall not affect the obligation of the Borrower to
repay such Loan in accordance with the terms of this Agreement; provided,
further, that if the designation of any such foreign branch or Affiliate shall
result in any costs, reductions or Taxes which would not otherwise have been
applicable and for which such Lender would, but for this proviso, be entitled to
request compensation under Section 2.15, 2.16 or 2.19, such Lender shall not be
entitled to request such compensation unless it shall in good faith have
determined such designation to be necessary or advisable to avoid any material
disadvantage to it.  Borrowings of more than one Type may be outstanding at the
same time; provided, however, that the Borrower shall not be entitled to request
any Borrowing which, if made, would result in an aggregate of more than 20
separate Borrowings (excluding Competitive Borrowings) being outstanding
hereunder at any one time.  For purposes of the fore  going, Borrowings having
different Interest Periods, regardless of whether they commence on the same
date, shall be considered separate Borrowings.

          (c)  Subject to Section 2.05 and paragraph (d) below, each Lender
shall make its Loans on the proposed date or dates thereof (i) in the case of
Revolving Loans and Competitive Loans, by wire transfer of immediately available
funds to the Servicing Agent in New York, New York, not later than 12:00 noon,
New York City time, and (ii) in the case of Swingline Loans, as provided for in
Section 2.06.  The Servicing Agent shall credit on such date the amounts so
received to the general deposit account of the Borrower with the Servicing Agent
or to another account specified by the Borrower and acceptable to the Servicing
Agent by 3:00 p.m., New York City time; provided that ABR Revolving Loans made
to finance the reimbursement of an LC Disbursement shall be 

 
                                                                              24

remitted by the Servicing Agent to the Fronting Bank; and provided, further,
that if a Borrowing shall not occur on such date because any condition precedent
herein specified shall not have been met, the Servicing Agent shall return the
amounts so received to the respective Lenders. Loans shall be made by the
Lenders in accordance with their Pro Rata Percentages as provided in Section
2.17 and Competitive Loans shall be made by the Lender or Lenders whose
Competitive Bids therefor are accepted pursuant to Section 2.03 in the amounts
so accepted. Unless the Servicing Agent shall have received notice from a Lender
prior to the date of any Borrowing that such Lender will not make available to
the Servicing Agent such Lender's portion of such Borrowing, the Servicing Agent
may assume that such Lender has made such portion available to the Servicing
Agent on the date of such Borrowing in accordance with this paragraph (c) and
the Servicing 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 made such portion available to the Servicing Agent, such
Lender and the Borrower severally agree to repay to the Servicing 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 Servicing Agent at (i) in the case of the
Borrower, the interest rate applicable to ABR Loans and (ii) in the case of such
Lender, the greater of the Federal Funds Effective Rate and a rate determined by
the Servicing Agent in accordance with banking industry rules on interbank
compensation. If such Lender shall repay to the Servicing Agent such
corresponding amount, such amount shall be deemed to constitute such Lender's
Loan as part of such Borrowing for purposes of this Agreement as if it were made
on the date of such Borrowing.

          (d)  Notwithstanding any other provision of this Agreement, the
Borrower shall not be entitled to request any Borrowing if the Interest Period
requested with respect thereto would end after the Maturity Date.

          SECTION 2.03.  Competitive Bid Procedure.  (a)  In order to request

of this Agreement, to make Competitive Loans pursuant to such Competitive Bid
Request.

          (b)  Each Lender may, in its sole discretion, make one or more
Competitive Bids to the Borrower responsive to a Competitive Bid Request.  Each
Competitive Bid by a Lender must be received by the Servicing Agent by
telecopier, in the form of Exhibit C-3, (i) in the case of a LIBOR Competitive
Borrowing, not later than 9:30 a.m., New York City time, three Business Days
before a proposed Competitive Borrowing and (ii) in the case of a Fixed Rate
Borrowing, not later than 9:30 a.m., New York City time, on the day of a
proposed Competitive Borrowing.  Multiple bids will be accepted by the Servicing
Agent.  Competitive Bids that do not conform substantially to the format of
Exhibit C-3 may be rejected by the Servicing Agent after conferring with, and
upon the instruction of, the Borrower, and the Servicing Agent shall notify the
Lender making such nonconforming bid of such rejection as soon as practicable.
Each Competitive Bid shall refer to this Agreement and specify (x) the principal
amount (which shall be in a minimum principal amount of $5,000,000 and which may
equal the entire principal amount of the Competitive Borrowing requested by the
Borrower) of the Competitive Loan that the Lender is willing to make to the
Borrower, (y) the Competitive Bid Rate or Rates at which such Lender is
prepared to make the Competitive Loan or Loans and (z) the Interest Period and
the last day thereof.  A Competitive Bid submitted by a Lender pursuant to this
paragraph (b) shall be irrevocable.

          (c)  The Servicing Agent shall promptly notify the Borrower by
telecopier of all the Competitive Bids made, the Competitive Bid Rate and the
principal amount of each Competitive Loan in respect of which a Competitive Bid
was made and the identity of the Lender that made each bid.  The Servicing Agent
shall send a copy of all Competitive Bids to the Borrower for its records as
soon as practicable after completion of the bidding process set forth in this
Section 2.03.

          (d)  The Borrower may in its sole and absolute discretion, subject
only to the provisions of this paragraph (d), accept or reject any Competitive
Bid referred to in paragraph (c) above.  

 
                                                                              26

The Borrower shall notify the Servicing Agent by telephone, confirmed by
telecopier in the form of a Competitive Bid Accept/Reject Letter in the form of
Exhibit C-4, whether and to what extent it has decided to accept or reject any
of or all the bids referred to in paragraph (c) above, (x) in the case of a
LIBOR Competitive Borrowing, not later than 10:30 a.m., New York City time,
three Business Days before a proposed Competitive Borrowing and (y) in the case
of a Fixed Rate Borrowing, not later than 10:30 a.m., New York City time, on the
day of a proposed Competitive Borrowing; provided, however, that (i) the failure
by the Borrower to give such notice shall be deemed to be a rejection of all the
bids referred to in paragraph (c) above, (ii) the Borrower shall not accept a
bid made at a particular Competitive Bid Rate with respect to any Competitive
Bid Request if the Borrower has decided to reject a bid made at a lower
Competitive Bid Rate with respect to such Competitive Bid Request, (iii) the
aggregate amount of the Competitive Bids accepted by the Borrower shall not
exceed the principal amount specified in such Competitive Bid Request, (iv) to
the extent necessary to comply with clause (iii) above, the Borrower may accept
Competitive Bids at a single Competitive Bid Rate in part, which acceptance, in
the case of multiple bids at such Competitive Bid Rate, shall be made pro rata
in accordance with the amount of each such Competitive Bid and (v) no bid shall
be accepted for a Competitive Loan unless such Competitive Loan is in a minimum
principal amount of $5,000,000; provided further, however, that, if a
Competitive Loan must be in an amount less than $5,000,000 because of the
provisions of clause (iv) above, such Competitive Loan may be for a minimum of
$1,000,000 or any integral multiple thereof, and in calculating the pro rata
allo cation of acceptances of portions of multiple bids at a particular
Competitive Bid Rate pursuant to clause (iv) the amounts shall be rounded to
integral multiples of $1,000,000 in a manner which shall be in the discretion of
the Borrower. A notice given by the Borrower pursuant to this paragraph (d)
shall be irrevocable.

          (e)  The Servicing Agent shall promptly notify each bidding Lender
whether or not its Competitive Bid has been accepted (and, if so, in what amount
and at what Competitive Bid Rate) by telecopier sent by the Servicing Agent, and
each successful bidder will thereupon become bound, subject to the other
applicable conditions hereof, to make the Competitive Loan in respect of which
its bid has been accepted.

          (f)  The Borrower may submit Competitive Bid Requests for more than
one Type of Loan or for more than one Interest Period at the same time on any
day, but no Competitive Bid Request shall be made within five Business Days
after any date on which one or more Competitive Bid Requests have previously
been submitted.

 
                                                                              27

          (g)  If the Servicing Agent shall elect to submit a Competitive Bid in
its capacity as a Lender, it shall submit such bid directly to the Borrower one-
quarter of an hour earlier than the latest time at which the other Lenders are
required to submit their bids to the Servicing Agent pursuant to paragraph (b)
above.

          (h)  All notices required by this Section 2.03 shall be given in
accordance with Section 10.01.

          SECTION 2.04.  Notice of Borrowings.  (a)  In order to request a
Revolving Borrowing, the Borrower shall give written or telecopy notice (or
telephone notice promptly confirmed in writing or by telecopy) to the Servicing
Agent in the form of Exhibit B (i) in the case of a LIBOR Revolving Borrowing,
not later than 11:00 a.m., New York City time, three Business Days before a
proposed Borrowing, (ii) in the case of a NIBOR Borrowing, not later than 11:00
a.m., New York City time, two Business Days before a proposed Borrowing and
(iii) in the case of an ABR Borrowing, not later than 11:00 a.m., New York City
time, on the day of a proposed Borrowing.  No Fixed Rate Loan shall be requested
or made pursuant to a Revolving Borrowing Request.

          (b)  The Servicing Agent may waive any prior notice in connection with
any Revolving Borrowing to be made on the date hereof.  Any notice given
pursuant to this Section 2.04 shall be irrevocable and shall in each case refer
to this Agreement and specify (x) whether such Borrowing is to be a LIBOR
Revolving Borrowing, a NIBOR Borrowing or an ABR Borrowing; (y) the date of such
Borrowing (which shall be a Business Day) and the amount thereof; and (z) if
such Borrowing is to be a LIBOR Borrowing or a NIBOR Borrowing, the Interest
Period with respect thereto.  If no election as to the Type of Borrowing is
specified in any such notice, then the requested Borrowing shall be an ABR
Borrowing. If no Interest Period with respect to any LIBOR Revolving Borrowing
or NIBOR Borrowing is specified in any such notice, then the applicable Borrower
shall be deemed to have selected an Interest Period of one week's duration.  The
Servicing Agent shall promptly advise the Lenders of each notice given pursuant
to this Section 2.04 and of each Lender's portion of the requested Borrowing.

          SECTION 2.05.  Conversions and Continuations.  Each Revolving
Borrowing initially shall be of the Type specified in the applicable Borrowing
Request and, in the case of a LIBOR Revolving Borrowing or a NIBOR Borrowing,
shall have an initial Interest Period as specified in such Borrowing Request.
Thereafter, the Borrower shall have the right at any time upon prior
irrevocable telephonic notice (which shall be confirmed promptly in writing or
by telecopy) to the Servicing Agent by the time that a Borrowing Request would
be required under Section 2.04 if the 

 
                                                                              28

Borrower were requesting a Revolving Borrowing of the Type resulting from such
election to be made on the effective date of such election, subject in each case
to the following:

          (a) if fewer than all the Loans comprising any Borrowing are to be
     converted or continued, such conversion or continuation shall be made pro
     rata among the Lenders in accordance with the respective Loans of such
     Lenders that are part of such Borrowing immediately prior to such
     conversion or continuation;

          (b) in the case of a conversion or continuation of fewer than all the
     Loans comprising any Borrowing, the aggregate principal amount of Loans
     converted or continued shall be an amount that would be a permitted
     Borrowing amount for Loans of the same Type under the third sentence of
     Section 2.02(a);

          (c) accrued interest on a Loan (or portion thereof) being converted or
     continued shall be paid by the Borrower at the time of conversion or
     continuation;

          (d) if any LIBOR Revolving Loan or NIBOR Loan is converted at a time
     other than the end of an Interest Period applicable thereto, the Borrower
     shall pay any increased costs associated therewith pursuant to Section
     2.16; and

          (e) no portion of a Loan may be converted into or continued as a LIBOR
     Revolving Loan or a NIBOR Loan with an Interest Period ending after the
     Maturity Date and any portion of a LIBOR Revolving Loan or NIBOR Loan for
     which the shortest available Interest Period would extend beyond such date
     shall be automatically converted at the end of the Interest Period at the
     time in effect into an ABR Loan.

          The Interest Period applicable to any LIBOR Revolving Loan or NIBOR
Loan resulting from a conversion of a Loan shall be specified by the Borrower in
the irrevocable notice of conversion delivered pursuant to this Section;
provided, however, that if no such Interest Period shall be specified, the
Borrower shall be deemed to have selected an Interest Period of one month's
duration, in the case of a LIBOR Loan, or one week's duration, in the case of a
NIBOR Loan.  If the Borrower shall not have given timely notice to continue any
Loan (other than a Competitive Loan or a Swingline Loan) into a subsequent
Interest Period (and shall not otherwise have given notice to convert such
Loan), such Loan (unless repaid pursuant to the terms hereof) shall, subject to
clauses (c) and (e) above, automatically be continued into a new Interest
Period, which shall be of one month's duration, in the case of a LIBOR Loan, or
one week's duration, in the case of a NIBOR Loan.  The Servicing Agent shall
promptly advise the Lenders 

 
                                                                              29

of any notice given pursuant to this Section and of each Lender's portion of the
continuation or conversion hereunder. This Section shall not apply to
Competitive Borrowings or Swingline Borrowings, which may not be converted or
continued.

          SECTION 2.06.  Swingline Loans.  (a)  Subject to the terms and
conditions set forth herein, the Swingline Lender agrees to make Swingline Loans
to the Borrower from time to time during the Availability Period, in an
aggregate principal amount at any time outstanding that will not result in (i)
the aggregate principal amount of outstanding Swingline Loans exceeding
$35,000,000 or (ii) the sum of the total Revolving Credit Exposures plus the
aggregate principal amount of outstanding Competitive Loans exceeding the Total
Commitment; provided that the Swingline Lender shall not be required to make a
Swingline Loan to refinance an outstanding Swingline Loan.  Within the foregoing
limits and subject to the terms and conditions set forth herein, the Borrower
may borrow, prepay and reborrow Swingline Loans.

          (b)  To request a Swingline Loan, the Borrower shall notify the
Swingline Lender of such request by telephone (confirmed by telecopy if
requested by the Swingline Lender), not later than 12:00 noon, New York City
time, on the day of a proposed Swingline Loan.  Each such notice shall be
irrevocable and shall specify the requested date (which shall be a Business Day)
and amount of the requested Swingline Loan and the Interest Period to be
applicable thereto.  If so requested by the Borrower, the Swingline Lender will
quote an interest rate that, if accepted by the Borrower, will be applicable to
the requested Swingline Loan, and the Borrower will promptly notify the
Swingline Lender in the event it accepts such rate.  The Swingline Lender will
promptly advise the Servicing Agent of any such notice received from the
Borrower.  The Swingline Lender shall make each Swingline Loan available to the
Borrower by means of a credit to the general deposit account of the Borrower
with the Swingline Lender (or, in the case of a Swingline Loan made to finance
the reimbursement of an LC Disbursement as provided in Section 2.07(e), by
remittance to the Fronting Bank) by 3:00 p.m., New York City time, on the
requested date of such Swingline Loan.

          (c)  The Swingline Lender may by written notice given to the Servicing
Agent not later than 10:00 a.m., New York City time, on any Business Day require
the Lenders to acquire participations on such Business Day in all or a portion
of the Swingline Loans outstanding.  Such notice shall specify the aggregate
amount of Swingline Loans in which Lenders will participate.  Promptly upon
receipt of such notice, the Servicing Agent will give notice thereof to each
Lender, specifying in such notice such Lender's Pro Rata Percentage of such
Swingline Loan or Loans.  Each Lender hereby absolutely and unconditionally
agrees, 

 
                                                                              30

upon receipt of notice as provided above, to pay to the Servicing Agent, for the
account of the Swingline Lender, such Lender's Pro Rata Percentage of such
Swingline Loan or Loans. Each Lender acknowledges and agrees that its obligation
to acquire participations in Swingline Loans pursuant to this paragraph is
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including the occurrence and continuance of a Default or reduction
or termination of the Commitments, and that each such payment shall be made
without any offset, abatement, withholding or reduction whatsoever. Each Lender
shall comply with its obligation under this paragraph by wire transfer of
immediately available funds, in the same manner as provided in Section 2.02 with
respect to Loans made by such Lender (and Section 2.02 shall apply, mutatis
mutandis, to the payment obligations of the Lenders), and the Servicing Agent
shall promptly pay to the Swingline Lender the amounts so received by it from
the Lenders. The Servicing Agent shall notify the Borrower of any participations
in any Swingline Loan acquired pursuant to this paragraph, and thereafter
payments in respect of such Swingline Loan shall be made to the Servicing Agent
and not to the Swingline Lender. Any amounts received by the Swingline Lender
from the Borrower (or other party on behalf of the Borrower) in respect of a
Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale
of participations therein shall be promptly remitted to the Servicing Agent; any
such amounts received by the Servicing Agent shall be promptly remitted by the
Servicing Agent to the Lenders that shall have made their payments pursuant to
this paragraph and to the Swingline Lender, as their interests may appear. Any
payment by a Lender pursuant to this paragraph to purchase a participation in a
Swingline Loan shall not constitute a Revolving Loan and shall not relieve the
Borrower of its obligation to repay such Swingline Loan.

          SECTION 2.07.  Letters of Credit.  (a)  General. Subject to the terms
and conditions set forth herein, the Borrower may request the issuance of
Letters of Credit for its own account, in a form reasonably acceptable to the
Servicing Agent and the Fronting Bank, at any time and from time to time during
the period beginning on the Effective Date and ending on the fifth Business Day
prior to the Maturity Date.  In the event of any inconsistency between the terms
and conditions of this Agreement and the terms and conditions of the letter of
credit application submitted by the Borrower to, or entered into by the Borrower
with, the Fronting Bank relating to any Letter of Credit, the terms and
conditions of this Agreement shall control.

          (b)  Notice of Issuance, Amendment, Renewal, Extension; Certain
Conditions.  To request the issuance of a Letter of Credit (or the amendment,
renewal or extension of an outstanding Letter of Credit), the Borrower shall
hand deliver or telecopy (or transmit by electronic communication, if 
arrangements for doing so 

 
                                                                              31

have been approved by the Fronting Bank) to the Fronting Bank and the Servicing
Agent (reasonably in advance of the requested date of issuance, amendment,
renewal or extension) a notice requesting the issuance of a Letter of Credit, or
identifying the Letter of Credit to be amended, renewed or extended, the date of
issuance, amendment, renewal or extension, the date on which such Letter of
Credit is to expire (which shall comply with paragraph (c) of this Section), the
amount of such Letter of Credit, the name and address of the beneficiary thereof
and such other information as shall be necessary to prepare, amend, renew or
extend such Letter of Credit. If requested by the Fronting Bank, the Borrower
also shall submit a letter of credit application in the form of Exhibit D hereto
in connection with any request for a Letter of Credit. A Letter of Credit shall
be issued, amended, renewed or extended only if (and upon issuance, amendment,
renewal or extension of each Letter of Credit the Borrower shall be deemed to
represent and warrant that), after giving effect to such issuance, amendment,
renewal or extension (i) the LC Exposure shall not exceed $100,000,000 and (ii)
the sum of the total Revolving Credit Exposures plus the aggregate principal
amount of outstanding Competitive Loans shall not exceed the Total Commitment.

          (c)  Expiration Date.  Each Letter of Credit shall expire at or prior
to the close of business on the earlier of (i) the date one year after the date
of the issuance of such Letter of Credit (or, in the case of any renewal or
extension thereof, one year after such renewal or extension) and (ii) the date
that is five Business Days prior to the Maturity Date.

          (d)  Participations.  By the issuance of a Letter of Credit (or an
amendment to a Letter of Credit increasing the amount thereof) and without any
further action on the part of the Fronting Bank or the Lenders, the Fronting
Bank hereby grants to each Lender, and each Lender hereby acquires from the
Fronting Bank, a participation in such Letter of Credit equal to such Lender's
Pro Rata Percentage of the aggregate amount available to be drawn under such
Letter of Credit.  In consideration and in furtherance of the foregoing, each
Lender hereby absolutely and unconditionally agrees to pay to the Servicing
Agent, for the account of the Fronting Bank, such Lender's Pro Rata Percentage
of each LC Disbursement made by the Fronting Bank and not reimbursed by the
Borrower on the date due as provided in paragraph (e) of this Section, or of any
reimbursement payment required to be refunded to the Borrower for any reason.
Each Lender acknowledges and agrees that its obligation to acquire
participations pursuant to this paragraph in respect of Letters of Credit is
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including any amendment, renewal or extension of any Letter of
Credit or the occurrence and continuance of a Default or reduction or
termination of the Commitments, and that each such payment shall be made without
any offset, abatement, withholding 

 
                                                                              32

or reduction whatsoever; provided that such participations by a Lender shall not
be construed as a waiver of any claims such Lender may have against the Fronting
Bank for gross negligence or wilful misconduct (as finally determined by a court
of competent jurisdiction).

          (e)  Reimbursement.  If the Fronting Bank shall make any LC
Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such
LC Disbursement by paying to the Servicing Agent an amount equal to such LC
Disbursement not later than 12:00 noon, New York City time, on the date that
such LC Disbursement is made, if the Borrower shall have received notice of such
LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if
such notice has not been received by the Borrower prior to such time on such
date, then not later than 12:00 noon, New York City time, on (i) the Business
Day that the Borrower receives such notice, if such notice is received prior to
10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day
immediately following the day that the Borrower receives such notice, if such
notice is not received prior to such time on the day of receipt; provided that
the Borrower may, subject to the conditions to the Borrowing set forth herein,
request in accordance with Section 2.04 or 2.06 that such payment be financed
with an ABR Revolving Borrowing or Swingline Loan in an equivalent amount and,
to the extent so financed, the Borrower's obligation to make such payment shall
be discharged and replaced by the resulting ABR Revolving Borrowing or Swingline
Loan.  If the Borrower fails to make such payment when due, the Servicing Agent
shall notify each Lender of the applicable LC Disbursement, the payment then due
from the Borrower in respect thereof and such Lender's Pro Rata Percentage
thereof.  Promptly following receipt of such notice, each Lender shall pay to
the Servicing Agent its Pro Rata Percentage of the payment then due from the
Borrower, in the same manner as provided in Section 2.02 with respect to Loans
made by such Lender (and Section 2.02 shall apply, mutatis mutandis, to the
payment obligations of the Lenders), and the Servicing Agent shall promptly pay
to the Fronting Bank the amounts so received by it from the Lenders.  Promptly
following receipt by the Servicing Agent of any payment from the Borrower
pursuant to this paragraph, the Servicing Agent shall distribute such payment to
the Fronting Bank or, to the extent that Lenders have made payments pursuant to
this paragraph to reimburse the Fronting Bank, then to such Lenders and the
Fronting Bank as their interests may appear.  Any payment made by a Lender
pursuant to this paragraph to reimburse the Fronting Bank for any LC
Disbursement (other than the funding of ABR Revolving Loans or a Swingline Loan
as contemplated above) shall not constitute a Loan and shall not relieve the
Borrower of its obligation to reimburse such LC Disbursement.

 
                                                                              33

          (f)  Obligations Absolute.  The Borrower's obligation to reimburse LC
Disbursements as provided in paragraph (e) of this Section shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement under any and all circumstances whatsoever and
irrespective of (i) any lack of validity or enforceability of any Letter of
Credit or this Agreement, or any term or provision therein, (ii) any draft or
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, (iii) payment by the Fronting Bank under a Letter of
Credit against presentation of a draft or other document that does not comply
with the terms of such Letter of Credit, or (iv) any other event or circumstance
whatsoever, whether or not similar to any of the foregoing, that might, but for
the provisions of this Section, constitute a legal or equitable discharge of, or
provide a right of setoff against, the Borrower's obligations hereunder.  None
of the Administrative Agents, the Lenders nor the Fronting Bank, nor any of
their Related Parties shall have any liability or responsibility by reason of or
in connection with the issuance or transfer of any Letter of Credit or any
payment or failure to make any payment thereunder (irrespective of any of the
circumstances referred to in the preceding sentence), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
Fronting Bank; provided that the foregoing shall not be construed to excuse the
Fronting Bank from liability to the Borrower to the extent of any direct damages
(as opposed to consequential damages, claims in respect of which are hereby
waived by the Borrower to the extent permitted by applicable law) suffered by
the Borrower that are caused by the Fronting Bank's failure to exercise care
when determining whether drafts and other documents presented under a Letter of
Credit comply with the terms thereof.  The parties hereto expressly agree that,
in the absence of gross negligence or wilful misconduct on the part of the
Fronting Bank (as finally determined by a court of competent jurisdiction), the
Fronting Bank shall be deemed to have exercised care in each such determination.
In furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their
face to be in substantial compliance with the terms of a Letter of Credit, the
Fronting Bank may, in its sole discretion, either accept and make payment upon
such documents without responsibility for further investigation, regardless of
any notice or information to the contrary, or refuse to accept and make payment
upon such documents if such documents are not in strict compliance with the
terms of such Letter of Credit.

 
                                                                              34

          (g)  Disbursement Procedures.  The Fronting Bank shall, promptly
following its receipt thereof, examine all documents purporting to represent a
demand for payment under a Letter of Credit.  The Fronting Bank shall promptly
notify the Servicing Agent and the Borrower by telephone (confirmed by telecopy)
of such demand for payment and whether the Fronting Bank has made or will make
an LC Disbursement thereunder; provided that any failure to give or delay in
giving such notice shall not relieve the Borrower of its obligation to reimburse
the Fronting Bank and the Lenders with respect to any such LC Disbursement.

          (h)  Interim Interest.  If the Fronting Bank shall make any LC
Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in
full on the date such LC Disbursement is made, the unpaid amount thereof shall
bear interest, for each day from and including the date such LC Disbursement is
made to but excluding the date that the Borrower reimburses such LC
Disbursement, at the rate per annum then applicable to ABR Revolving Loans;
provided that, if the Borrower fails to reimburse such LC Disbursement when due
pursuant to paragraph (e) of this Section, then Section 2.11 shall apply.
Interest accrued pursuant to this paragraph shall be for the account of the
Fronting Bank, except that interest accrued on and after the date of payment by
any Lender pursuant to paragraph (e) of this Section to reimburse the Fronting
Bank shall be for the account of such Lender to the extent of such payment.

          (i)  Replacement of the Fronting Bank.  The Fronting Bank may be
replaced at any time by written agreement among the Borrower, the Administrative
Agents, the replaced Fronting Bank and the successor Fronting Bank.  The
Servicing Agent shall notify the Lenders of any such replacement of the Fronting
Bank. At the time any such replacement shall become effective, the Borrower
shall pay all unpaid fees accrued for the account of the replaced Fronting Bank
pursuant to Section 2.08(b).  From and after the effective date of any such
replacement, (i) the successor Fronting Bank shall have all the rights and
obligations of the Fronting Bank under this Agreement with respect to Letters of
Credit to be issued thereafter and (ii) references herein to the term "Fronting
Bank" shall be deemed to refer to such successor or to any previous Fronting
Bank, or to such successor and all previous Fronting Banks, as the context shall
require. After the replacement of an Fronting Bank hereunder, the replaced
Fronting Bank shall remain a party hereto and shall continue to have all the
rights and obligations of a Fronting Bank under this Agreement with respect to
Letters of Credit issued by it prior to such replacement, but shall not be
required to issue additional Letters of Credit.

          (j)  Cash Collateralization.  If any Event of Default shall occur and
be continuing and the maturity of the Loans shall 

 
                                                                              35

be accelerated or the Commitments terminated as provided in Article VII, on the
Business Day that the Borrower receives notice from the Administrative Agents or
Lenders with LC Exposure representing greater than 50% of the total LC Exposure
demanding the deposit of cash collateral pursuant to this paragraph, the
Borrower shall deposit in an account with the Servicing Agent, in the name of
the Servicing Agent and for the benefit of the Lenders, an amount in cash equal
to the LC Exposure as of such date plus any accrued and unpaid interest thereon;
provided that the obligation to deposit such cash collateral shall become
effective immediately, and such deposit shall become immediately due and
payable, without demand or other notice of any kind, upon the occurrence of any
Event of Default with respect to the Borrower described in clause (e) or (f) of
Article VII. Such deposit shall be held by the Servicing Agent as collateral for
the payment and performance of the obligations of the Borrower under this
Agreement. The Servicing Agent shall have exclusive dominion and control,
including the exclusive right of withdrawal, over such account. Such deposits
shall, pending their application as provided below, be invested by the Servicing
Agent, at the Borrower's risk and expense, in repurchase obligations with
respect to United States Treasury securities or other high-quality overnight or
short-term investments (which may include certificates of deposit of BofA), and
any interest earned through the investment of such deposits shall be for the
Borrower's account and shall be added to the deposits held by the Servicing
Agent under this Section and applied as provided herein. Moneys in such account
shall be applied by the Servicing Agent to reimburse the Fronting Bank for LC
Disbursements for which it has not been reimbursed and, to the extent not so
applied, shall be held for the satisfaction of the reimbursement obligations of
the Borrower for the LC Exposure at such time or, subject to the consent of
Lenders with LC Exposure representing greater than 50% of the total LC Exposure,
be applied to satisfy other obligations of the Borrower under this Agreement. If
the Borrower is required to provide an amount of cash collateral hereunder as a
result of the occurrence of an Event of Default, such amount, together with any
interest earned thereon (to the extent not applied as aforesaid), shall be
returned to the Borrower within three Business Days after all Events of Default
have been cured or waived.

          SECTION 2.08.  Fees.  (a)  The Borrower agrees to pay to each Lender,
through the Servicing Agent, on each March 31, June 30, September 30 and
December 31, commencing December 31, 1997, and on the date on which the
Commitment of such Lender shall be terminated as provided herein, a facility fee
(the "Facility Fee") equal to the Applicable Percentage in effect from time to
time on the amount of the Commitment of such Lender, whether used or unused,
during the preceding quarter (or other period commencing on the Closing Date or
ending on the Maturity Date or 

 
                                                                              36

any date on which the Commitment of such Lender shall be terminated). The
Facility Fee shall be computed on the basis of the actual number of days elapsed
over a year of 360 days (including the first day but excluding the last day).
The Facility Fee due to each Lender shall commence to accrue on the Closing Date
and shall cease to accrue on the earlier of the Maturity Date and the
termination of the Commitment of such Lender as provided herein.

          (b)  The Borrower agrees to pay (i) to the Servicing Agent for the
account of each Lender a participation fee with respect to its participations in
Letters of Credit, which shall accrue at the same Applicable Percentage as shall
be used in determining the interest rate applicable to LIBOR Revolving Loans on
the average daily amount of such Lender's LC Exposure (excluding any portion
thereof attributable to unreimbursed LC Disbursements) during the period from
and including the Closing Date to but excluding the later of the date on which
such Lender's Commitment terminates and the date on which such Lender ceases to
have any LC Exposure, and (ii) to the Fronting Bank a fronting fee, which shall
accrue at the rate of 0.100% per annum on the average daily amount of the LC
Exposure (excluding any portion thereof attributable to unreimbursed LC
Disbursements) during the period from and including the Closing Date to but
excluding the later of the date of termination of the Commitments and the date
on which there ceases to be any LC Exposure. Participation fees and fronting
fees shall be payable on each March 31, June 30, September 30 and December 31,
commencing March 31, 1998; provided that all such fees shall be payable on the
date on which the Commitments terminate and any such fees accruing after the
date on which the Commitments terminate shall be payable on demand.  All
participation fees and fronting fees shall be computed on the basis of a year of
360 days and shall be payable for the actual number of days elapsed (including
the first day but excluding the last day).

          (c)  The Borrower agrees to pay to the Administrative Agents, for
their respective accounts, agent and administrative fees (the "Administrative
Fees") at the times and in the amounts agreed upon in the fee letter agreements
dated October 9, 1997, between Lyondell and Millennium and BofA and between
Lyondell and Millennium and Chase, respectively.

          (d)  All Fees shall be paid on the dates due, in immediately available
funds, to the Servicing Agent (or to the Fronting Bank, in the case of fees
payable to it) for distribution, if and as appropriate, among the Lenders.  The
Administrative Fees of BofA and Chase shall be paid on the dates due, in
immediately available funds, to BofA and Chase directly. Once paid, none of the
Fees shall be refundable under any circumstances.

 
                                                                              37

          SECTION 2.09.  Repayment of Loans; Evidence of Debt. (a)  The Borrower
hereby agrees as to Loans made to it that (i) the outstanding principal balance
of each Revolving Loan shall be payable on the Maturity Date, (ii) the
outstanding principal balance of each Competitive Loan shall be payable on the
last day of the Interest Period applicable thereto and (iii) the outstanding
principal balance of each Swingline Loan shall be payable to the Swingline
Lender on the last day of the Interest Period applicable to such Swingline Loan;
provided that on each date that a Revolving Borrowing or Competitive Borrowing
is made, the Borrower shall repay all Swingline Loans then outstanding.

          (b)  Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness to such Lender resulting from
each Loan made by such Lender from time to time, including the amounts of
principal and interest payable and paid to such Lender from time to time under
this Agreement.

          (c)  The Servicing Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Class and Type of each
Loan and the Interest Period applicable thereto, (ii) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Servicing Agent hereunder for the account of the Lenders and each Lender's
share thereof.

          (d)  The entries made in the accounts maintained pursuant to
paragraphs (b) and (c) above shall, to the extent permitted by applicable law,
be prima facie evidence of the existence and amounts of the obligations therein
recorded; provided, however, that the failure of any Lender or the Servicing
Agent to maintain such accounts or any error therein shall not in any manner
affect the obligations of the Borrower to repay the Loans in accordance with
their terms.

          (e)  Notwithstanding any other provision of this Agreement, in the
event any Lender shall request a promissory note or notes evidencing the Loans
made by it hereunder, the Borrower shall deliver such a note or notes,
satisfactory to the Administrative Agents, payable to such Lender and its
registered assigns, and the interests represented by such note or notes shall at
all times (including after any assignment of all or part of such interests
pursuant to Section 10.07) be represented by one or more promissory notes
payable to the payee named therein or its registered assigns.

          SECTION 2.10.  Interest on Loans.  (a)  Subject to the provisions of
Section 2.11, each ABR Loan (including any Swingline Loan that is not bearing
interest at a rate quoted by the 

 
                                                                              38

Swingline Lender in accordance with paragraph (d) below) shall bear interest
(computed on the basis of the actual number of days elapsed over a year of 365
or 366 days, as the case may be, for periods during which the Alternate Base
Rate is determined by reference to the Reference Rate and 360 days for other
periods) at a rate per annum equal to the Alternate Base Rate. Interest on each
ABR Loan shall be payable on each applicable Interest Payment Date. The
Alternate Base Rate shall be determined by the Servicing Agent, and such
determination shall be conclusive absent manifest error.

          (b)  Subject to the provisions of Section 2.11, (i) each LIBOR Loan
(other than a LIBOR Competitive Loan) and each NIBOR Loan shall bear interest
(computed on the basis of the actual number of days elapsed over a year of 360
days) at a rate per annum equal to the LIBO Rate or NIBO Rate, as the case may
be, for the Interest Period in effect for such Loan plus the Applicable
Percentage, and (ii) each LIBOR Competitive Loan shall bear interest (computed
on the basis of the actual number of days elapsed over a year of 360 days) at a
rate per annum equal to the LIBO Rate for the Interest Period in effect for such
Competitive Loan plus (or minus, as applicable) the Margin offered by the Lender
making such Competitive Loan and accepted by the Borrower pursuant to Section
2.03.  Interest on each LIBOR Loan shall be payable on each applicable Interest
Payment Date (and, in the case of Revolving Loans, upon termination of the
Commitments). The LIBO Rate or NIBO Rate, as applicable, for each Interest
Period shall be determined by the Servicing Agent, and such determination shall
be conclusive absent manifest error.  The Servicing Agent shall promptly advise
the Borrower and each applicable Lender of such determination.

          (c)  Subject to the provisions of Section 2.11, each Fixed Rate Loan
shall bear interest at a rate per annum (computed on the basis of the actual
number of days elapsed over a year of 360 days) equal to the fixed rate of
interest offered by the Lender making such Loan and accepted by the Borrower
pursuant to Section 2.03.  Interest on each Fixed Rate Loan shall be payable on
the Interest Payment Dates applicable to such Loan except as otherwise provided
in this Agreement.

          (d)  Subject to the provisions of Section 2.11, each Swingline Loan
shall bear interest at (i) the rate per annum applicable to ABR Loans as
provided in paragraph (a) above or (ii) any other rate per annum (computed on
the basis of the actual number of days elapsed over a year of 360 days) which
shall be quoted by the Swingline Lender on the date such Loan is made and
accepted by the Borrower as provided in Section 2.06; provided, that commencing
on any date on which the Swingline Lender requires the Lenders to acquire
participations in a Swingline Loan pursuant 

 
                                                                              39

to Section 2.06(c), such Loan shall bear interest at the rate per annum
applicable to ABR Loans as provided in paragraph (a) above.

          (e)  Interest on each Loan shall accrue from and including the date on
which such Loan is made and to but excluding the date such Loan is repaid.

          SECTION 2.11.  Interest on Overdue Amounts; Alternative Rate of
Interest.  (a)  If the Borrower shall default in the payment of the principal of
or interest on any Loan or any Fees or other amount becoming due hereunder,
whether by scheduled maturity, notice of prepayment, acceleration or otherwise,
the Borrower shall on demand from time to time from the Servicing Agent pay
interest from and including the date of such default, to the extent permitted by
law, on such defaulted amount up to (but not including) the date of actual
payment (after as well as before judgment) at a rate per annum (computed as
provided in Section 2.10(a)) equal to (i) in the case of the principal of any
Loan, the rate otherwise applicable to such Loan plus 2% per annum and (ii) in
the case of any other amount, the Alternate Base Rate plus 2% per annum.

          (b)  In the event, and on each occasion, that on the day two Business
Days prior to the commencement of any Interest Period for a LIBOR Borrowing or
NIBOR Borrowing the Servicing Agent shall have determined that deposits in the
requested principal amounts of the LIBOR Loans or NIBOR Loans, as applicable,
are not generally available in the London interbank market or the New York
interbank market, as applicable, to the Required Lenders (or, in the case of a
LIBOR Competitive Loan, the Lender that is required to make such Loan) or that
reasonable means do not exist for ascertaining the LIBO Rate or the NIBO Rate or
that the rate at which such deposits are being offered will not adequately and
fairly reflect the cost to the Required Lenders (or, in the case of a LIBOR
Competitive Loan, the Lender that is required to make such Loan) of making such
LIBOR Loan or NIBOR Loan, as applicable, during such Interest Period, the
Servicing Agent shall, as soon as practicable thereafter, give written or
telecopy notice of such determination to the Borrower and any request by the
Borrower for a LIBOR Borrowing or a NIBOR Borrowing shall, until the
circumstances giving rise to such notice no longer exist, (i) if such notice
relates to a Revolving Borrowing, be deemed a request for an ABR Borrowing;
provided, however, that the Borrower may withdraw any such request prior to the
making of any such ABR Borrowing, (ii) if such notice relates to the conversion
of any Revolving Borrowing to, or continuation of any Revolving Borrowing as, a
LIBOR Borrowing or a NIBOR Borrowing, be deemed ineffective, as applicable, or
(iii) if such notice relates to a LIBOR Competitive Borrowing, be deemed
ineffective; provided that (A) if the circumstances giving rise to such notice
do not affect all the Lenders, then requests by the Borrower for LIBOR

 
                                                                              40

Competitive Borrowings may be made to Lenders that are not affected thereby and
(B) if the circumstances giving rise to such notice affect only one Type of
Borrowings, then the other Type of Borrowings shall be permitted. Each
determination by the Servicing Agent hereunder shall be conclusive absent
manifest error.

          SECTION 2.12.  Termination and Reduction of Commitments.  (a)  Unless
previously terminated, the Commitments shall be automatically and permanently
terminated on the Maturity Date.

          (b)  Upon at least three Business Days' prior irrevocable written or
telecopy notice to the Servicing Agent (a copy of which the Servicing Agent
shall promptly provide to each Lender), the Borrower may at any time in whole
permanently terminate, or from time to time in part permanently reduce, the
Total Commitment; provided, however, that (i) each partial reduction of the
Total Commitment shall be in an integral multiple of $1,000,000 and in a minimum
principal amount of $25,000,000 and (ii) no such termination or reduction shall
be made (A) which would reduce the Total Commitment to an amount less than the
sum of the aggregate Revolving Credit Exposures plus the aggregate principal
amount of outstanding Competitive Loans or (B) which would reduce any Lender's
Commitment to an amount that is less than the sum of such Lender's Revolving
Credit Exposure.

          (c)  Each reduction in the Total Commitment hereunder shall be made
ratably among the Lenders in accordance with their respective Commitments.  The
Borrower shall pay to the Servicing Agent for the account of the Lenders, on the
date of each termination or reduction of the Total Commitment, the Facility Fee
on the amount of the Total Commitment so terminated or reduced accrued through
the date of such termination or reduction.

          SECTION 2.13.  Prepayment of Loans.  (a)  The Borrower shall have the
right at any time and from time to time to prepay any Borrowing, in whole or in
part, upon giving telephonic notice (which shall be confirmed promptly in
writing or by telecopy) to the Servicing Agent (which shall promptly provide a
copy to each Lender):  (i) before 11:00 a.m., New York City time, three Business
Days prior to prepayment, in the case of LIBOR Loans or NIBOR Loans, (ii) before
11:00 a.m., New York City time, one Business Day prior to prepayment, in the
case of ABR Loans and (iii) before 12:00 noon, New York City time, on the date
of prepayment, in the case of Swingline Loans; provided, however, that each such
partial prepayment of principal shall be in a minimum principal amount of
$1,000,000 and an integral multiple of $1,000,000.  The Borrower shall not have
the right to prepay any Competitive Borrowing without the prior consent of the
Lender thereof.

 
                                                                              41

          (b)  On the date of any termination or reduction of the Total
Commitment pursuant to Section 2.12, the Borrower shall pay or prepay so much of
the Borrowings as shall be necessary in order that the sum of the aggregate
Revolving Credit Exposures plus the aggregate principal amount of outstanding
Competitive Loans will not exceed the Total Commitment after giving effect to
such termination or reduction.

          (c)  Except to the extent otherwise specified by the Borrower making a
prepayment, all prepayments under this Section 2.13 shall be applied to
outstanding ABR Loans up to the full amount thereof and then shall be applied to
outstanding LIBOR Loans (other than LIBOR Competitive Loans) up to the full
amount thereof.

          (d)  All prepayments under this Section shall be subject to Section
2.16 but otherwise without premium or penalty. All prepayments other than
prepayments of ABR Loans shall be accompanied by accrued interest on the
principal amount being prepaid to the date of prepayment.

          SECTION 2.14.  Reserve Requirements; Change in Circumstances.  (a)
Notwithstanding any other provision herein (but subject to paragraph (d) below
and Section 2.20), if after the date of this Agreement any change in applicable
law or regulation or in the interpretation or administration thereof by any
Governmental Authority charged with the interpretation or administration thereof
(whether or not having the force of law) shall change the basis of taxation of
payments to any Lender or the Fronting Bank, as applicable, of the principal of
or interest on any LIBOR Loan, NIBOR Loan or Fixed Rate Loan made by such Lender
or any Letter of Credit or participation therein or any fees or other amounts
payable hereunder (other than changes in respect of Taxes referred to in clause
(a) or (b) of the definition of "Excluded Taxes") or by any political
subdivision or taxing authority therein), or shall impose, modify or deem
applicable any reserve, special deposit or similar requirement against assets
of, deposits with or for the account of or credit extended by such Lender or
Fronting Bank or shall impose on such Lender, the Fronting Bank or the London
interbank market any other condition affecting this Agreement or LIBOR Loans,
NIBOR Loans or Fixed Rate Loans made by such Lender or any Letter of Credit or
participation therein, and the result of any of the foregoing shall be to
increase the cost to such Lender of making or maintaining any such Loan or to
increase the cost to such Lender or the Fronting Bank of participating in,
issuing or maintaining any Letter of Credit or to reduce the amount of any sum
received or receivable by such Lender or the Fronting Bank hereunder (whether of
principal, interest or otherwise) in respect thereof by an amount deemed by such
Lender to be material, then the Borrower 

 
                                                                              42

will pay to such Lender or the Fronting Bank, as the case may be, upon demand
such additional amount or amounts as will compensate such Lender or the Fronting
Bank for such additional costs incurred or reduction suffered.

          (b)  Subject to Section 2.20, if any Lender or the Fronting Bank shall
have determined that the adoption after the date hereof of any law, rule,
regulation or guideline regarding capital adequacy, or any change after the date
hereof in any of the foregoing or in the interpretation or administration of any
of the foregoing by any Governmental Authority charged with the interpretation
or administration thereof, or compliance by any Lender or the Fronting Bank (or
any lending office of such Lender or the Fronting Bank) or any Lender's or the
Fronting Bank's holding company with any request or directive regarding capital
adequacy (whether or not having the force of law) made or promulgated after the
date hereof by any such Governmental Authority, has or would have the effect of
reducing the rate of return on such Lender's or the Fronting Bank's capital or
on the capital of such Lender's or the Fronting Bank's holding company, if any,
as a consequence of its obligations under this Agreement or the Loans made by,
or participations in Letters of Credit held by, such Lender, or the Letters of
Credit issued by the Fronting Bank, pursuant hereto to a level below that which
such Lender or the Fronting Bank or such Lender's or the Fronting Bank's holding
company could have achieved but for such adoption, change or compliance (taking
into consideration such Lender's or the Fronting Bank's guidelines with respect
to capital adequacy) by an amount deemed by such Lender or the Fronting Bank to
be material, then from time to time the Borrower shall pay to such Lender or the
Fronting Bank such additional amount or amounts as will compensate such Lender
or the Fronting Bank or such Lender's or the Fronting Bank's holding company for
any such reduction suffered.

          (c)  A certificate of each Lender or the Fronting Bank setting forth
such amount or amounts as shall be necessary to compensate such Lender or the
Fronting Bank (or its participating banks or other entities pursuant to Section
10.07) as specified in paragraph (a) or (b) above, as the case may be, shall be
delivered to the Borrower and shall be conclusive absent manifest error.  Except
as provided in paragraph (d) below, the Borrower shall pay each Lender or the
Fronting Bank the amount shown as due on any such certificate delivered by such
Lender or the Fronting Bank within 30 days after receipt of the same.  Each
Lender or the Fronting Bank shall submit such a certificate no more often than
monthly; provided, however, that certificates with respect to amounts due with
respect to identifiable Loans may be submitted at the ends of such Loans'
Interest Periods.

 
                                                                              43

          (d)  Failure on the part of any Lender or the Fronting Bank to demand
compensation for any increased costs or reduction in amounts received or
receivable or reduction in return on capital shall not constitute a waiver of
such Lender's or the Fronting Bank's rights with respect to any period to demand
compensation for any increased costs or reduction in amounts received or
receivable or reduction in return on capital with respect to such period or any
other period; provided, however, that neither any Lender nor the Fronting Bank
shall be entitled to compensation under this Section 2.14 for any costs incurred
or reductions suffered more than 90 days prior to the date on which it shall
have requested compensation therefor; provided further, that if the change in
law or regulation or in the interpretation or administration thereof that shall
give rise to any such costs or reductions shall be retroactive, then the 90-day
period referred to above shall be extended to include the period of retroactive
effect thereof.  Notwithstanding any other provision of this Section 2.14,
neither any Lender nor the Fronting Bank shall demand compensation for any
increased cost or reduction referred to above if it shall not at the time be the
general policy or practice of such Lender or the Fronting Bank to demand such
compensation in similar circumstances under comparable provisions of other
credit agreements, if any.  If any Lender or the Fronting Bank shall receive as
a refund any moneys from any source that it has listed on the certificate
provided pursuant to (c) above as an increased cost, to the extent that the
Borrower has previously paid such increased cost to such Lender or the Fronting
Bank, such Lender or the Fronting Bank shall promptly forward such refund to the
Borrower without interest.

          (e)  Notwithstanding the foregoing provisions of this Section, no
Lender shall demand compensation pursuant to this Section in respect of any
Competitive Loan for any increased cost or reduction referred to above if the
circumstance that would otherwise entitle it to such compensation shall have
been publicly announced prior to submission of the Competitive Bid pursuant to
which such Loan was made.

          SECTION 2.15.  Change in Legality.  (a)  Notwithstanding anything to
the contrary herein contained (but subject to Section 2.20), if after the date
of this Agreement any change in any law or regulation or in the interpretation
thereof or any new law, regulation or interpretation by any Governmental
Authority charged with the administration or interpretation thereof or any
judgment, order or directive of any competent court, tribunal or authority shall
make it unlawful for any Lender or its Applicable Lending Office to make or
maintain any LIBOR Loan or NIBOR Loan or to give effect to its obligations as
contemplated hereby with respect to any LIBOR Loan or NIBOR Loan (collectively,
an 

 
                                                                              44

"Illegality"), then, by written notice to the Borrower and to the Servicing
Agent, such Lender, so long as such Illegality continues to exist:

          (i) may declare that LIBOR Loans or NIBOR Loans, as applicable, will
     not thereafter be made by such Lender hereunder, whereupon any request by
     the Borrower for a LIBOR Borrowing or a NIBOR Borrowing, as applicable, (x)
     shall, as to such Lender only, be deemed a request for an ABR Borrowing or
     (y) at the option of the Borrower, shall be withdrawn as to the Lender
     prior to the time for making the Borrowing; and

          (ii) shall promptly enter into negotiations with the Borrower and
     negotiate in good faith to agree to a solution to such Illegality;
     provided, however, that if such an agreement has not been reached by the
     date at which such change in law is given effect with respect to the
     outstanding LIBOR Loans or NIBOR Loans of such Lender, the Borrower shall
     immediately prepay the affected Loans.

          (b)  For purposes of this Section 2.15, a notice by a Lender shall be
effective as to each Loan, if lawful, on the last day of the then current
Interest Period with respect thereto; provided, however, that such notice shall
be effective on the date of receipt if there are no outstanding LIBOR Loans or
NIBOR Loans; provided further, that if it is not lawful for such Lender to
maintain any Loan in its current form until the end of the Interest Period
applicable thereto, then the notice shall be effective upon receipt.

          (c)  Each Lender that has delivered a notice of Illegality pursuant to
paragraph (a) above agrees that it will notify the Borrower as soon as
practicable if the conditions giving rise to the Illegality cease to exist.

          SECTION 2.16.  Indemnity.  The Borrower agrees to indemnify each
Lender against any loss or expense which such Lender may sustain or incur as a
consequence of (a) any payment, prepayment or conversion of a LIBOR Loan, NIBOR
Loan or Fixed Rate Loan made to it required by any provision of this Agreement
or otherwise made, or any transfer of any such Loan pursuant to Section 2.20(b),
on a date other than the last day of the applicable Interest Period, (b) any
default in payment or prepayment of the principal amount of any Loan made to
it or any part thereof or interest accrued thereon, as and when due and payable
(whether at scheduled maturity, by notice of prepayment, acceleration or
otherwise), (c) the occurrence of any Event of Default, including any loss
sustained or incurred or to be sustained or incurred in liquidating or
employing deposits from third parties acquired to effect or maintain such Loan
or any part thereof as a LIBOR Loan, NIBOR Loan or Fixed Rate Loan, (d) any

 
                                                                              45

failure by the Borrower to fulfill on the date of any Borrowing by it hereunder
the applicable conditions set forth in Article IV, (e) any failure of the
Borrower to borrow or to convert or continue any Loan made to it hereunder after
irrevocable notice of such Borrowing, conversion or continuation has been
given pursuant to Section 2.03, 2.04 or 2.05 or (f) any failure of the Borrower
to borrow any Competitive Loan after accepting the Competitive Bid to make such
Loan.  Such loss or expense shall be the difference as reasonably determined by
such Lender between (x) an amount equal to the principal amount of such LIBOR
Loan, NIBOR Loan or Fixed Rate Loan being paid, prepaid, converted or
transferred or not borrowed, converted or continued multiplied by a percentage
per annum (computed on the basis of a 360-day year and actual days remaining for
the balance of the Interest Period applicable, or which would have been
applicable, to such LIBOR Loan, NIBOR Loan or Fixed Rate Loan being paid,
prepaid, converted, transferred or not borrowed, converted or continued) equal
to the greater of (i) the LIBO Rate or NIBO Rate applicable to such LIBOR Loan
or NIBOR Loan being paid, prepaid, converted or transferred or not borrowed,
converted or continued or, in the case of a Fixed Rate Loan, the fixed rate of
interest applicable thereto or (ii) such Lender's cost of obtaining the funds
for such LIBOR Loan, NIBOR Loan or such Fixed Rate Loan being paid, prepaid,
converted, transferred or not borrowed, converted or continued, but in the case
of LIBOR Loans or NIBOR Loans, not in excess of the LIBO Rate or NIBO Rate
applicable to such Loan plus 1/16th of 1% per annum, and (y) any lesser amount
that would be realized by such Lender in reemploying the funds received in
payment, prepayment, conversion or transfer or as a result of the failure to
borrow, convert or continue during the period from the date of such payment,
prepayment, conversion or transfer or failure to borrow, convert or continue to
the end of the Interest Period applicable to such LIBOR Loan, NIBOR Loan or
Fixed Rate Loan at the interest rate that would apply to an interest period of
approximately such duration.  Any such Lender shall provide to the Borrower a
statement explaining the amount of any such loss or expense, which statement
shall, in the absence of manifest error, be conclusive.

          SECTION 2.17.  Pro Rata Treatment.  Each Revolving Borrowing, each
payment of the Facility Fee and each reduction of the Total Commitment shall be
allocated among the Lenders in accordance with their respective Pro Rata
Percentages.  Except as required under Section 2.15, each payment or prepayment
of principal of any Revolving Borrowing and each continuation or conversion of
any Revolving Borrowing shall be allocated pro rata among the Lenders in
accordance with the respective principal amounts of their outstanding Revolving
Loans comprising such Borrowing.  Each payment of interest on any Revolving
Borrowing shall be allocated pro rata among the Lenders in accordance with the
respective amounts of accrued and unpaid interest on their outstanding Revolving
Loans comprising such Borrowing.  Each 

 
                                                                              46

payment of principal of any Competitive Borrowing shall be allocated pro rata
among the Lenders participating in such Borrowing in accordance with the
respective principal amounts of their outstanding Competitive Loans comprising
such Borrowing. Each payment of interest on any Competitive Borrowing shall be
allocated pro rata among the Lenders participating in such Borrowing in
accordance with the respective amounts of accrued and unpaid interest on their
outstanding Competitive Loans comprising such Borrowing. Each payment of
interest on any Swingline Borrowing or LC Disbursement shall be allocated in
accordance with Sections 2.06 and 2.07, respectively.

          SECTION 2.18.  Sharing of Setoffs.  Each Lender agrees that if it
shall, through the exercise of a right of banker's lien, setoff or counterclaim
or pursuant to a secured claim under Section 506 of Title 11 of the United
States Code or other security or interest arising from, or in lieu of, such
secured claim, received by such Lender under any applicable bankruptcy,
insolvency or other similar law or otherwise, obtain payment (voluntary or
involuntary) in respect of any Revolving Loans or participations in LC
Disbursements or Swingline Loans as a result of which the unpaid principal
portion of its Revolving Loans or participations in LC Disbursements or
Swingline Loans shall be proportionately less than the unpaid principal portion
of the Revolving Loans or participations in LC Disbursements or Swingline Loans
of any other Lender, it shall be deemed simultaneously to have purchased from
such other Lender at face value, and shall promptly pay to such other Lender the
purchase price for, a participation in the applicable Revolving Loans or
participations in LC Disbursements or Swingline Loans of such other Lender, so
that the aggregate unpaid principal amount of such Revolving Loans or
participations in LC Disbursements or Swingline Loans and participations in the
foregoing held by each Lender shall be in the same proportion to the aggregate
unpaid principal amount of all such Revolving Loans or participations in LC
Disbursements or Swingline Loans then outstanding as the principal amount of its
Revolving Loans or participations in LC Disbursements or Swingline Loans prior
to such exercise of banker's lien, setoff or counterclaim or other event was to
the principal amount of all such Revolving Loans or participations in LC
Disbursements or Swingline Loans outstanding prior to such exercise of such
banker's lien, setoff or counterclaim or other event; provided, however, that
(i) if any such purchase or adjustments shall be made pursuant to this Section
2.18 and the payment giving rise thereto shall thereafter be recovered, such
purchase or purchases or adjustments shall be rescinded to the extent of such
recovery and the purchase price or prices or adjustment restored without
interest and (ii) the provisions of this Section shall not be construed to apply
to any payment obtained by a Lender as consideration for the assignment of or
sale of a participation in any of its Loans or participations in LC
Disbursements or 

 
                                                                              47

Swingline Loans to any assignee or participant other than the Borrower or any
Affiliate thereof. The Borrower expressly consents to the foregoing arrangements
and agrees that any Lender holding a participation in a Loan made to it or
participations in LC Disbursements or Swingline Loans deemed to have been so
purchased may exercise any and all rights of banker's lien, setoff or
counterclaim with respect to any and all moneys owing by the Borrower to such
Lender by reason thereof as fully as if such Lender had made a Loan directly to
the Borrower in the amount of such participation.

          SECTION 2.19.  Taxes.  (a)  Any and all payments by or on account of
any obligation of the Borrower hereunder shall be made free and clear of and
without deduction for any Indemnified Taxes or Other Taxes; provided that if the
Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from
such payments, then (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) the Administrative Agent, Servicing
Agent, Lender (which term, as used in this Section, shall include any assignee
or transferee of a Lender, including any participation holder, subject to
Section 10.07) or Fronting Bank (as the case may be) receives an amount equal to
the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions and (iii) the Borrower shall pay the full
amount deducted to the relevant Governmental Authority in accordance with
applicable law.

          (b)  In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

          (c)  The Borrower shall indemnify each Administrative Agent, the
Servicing Agent, each Lender and the Fronting Bank, within 10 days after written
demand therefor, for the full amount of any Indemnified Taxes or Other Taxes
paid by such Administrative Agent, the Servicing Agent, such Lender or the
Fronting Bank, as the case may be, on or with respect to any payment by or on
account of any obligation of the Borrower hereunder (including Indemnified Taxes
or Other Taxes imposed or asserted on or attributable to amounts payable under
this Section) and any penalties, interest and reasonable expenses arising
therefrom or with respect thereto, whether or not such Indemnified Taxes or
Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority.  A certificate as to the amount of such payment or
liability delivered to the Borrower by an Administrative Agent, a Lender or the
Fronting Bank, or by the Servicing Agent on its own behalf or on behalf of a
Lender or the Fronting Bank, shall be conclusive absent manifest error.

 
                                                                              48

          (d)  As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
deliver to the Servicing Agent the original or a certified copy of a receipt
issued by such Governmental Authority evidencing such payment, a copy of the
return reporting such payment or other evidence of such payment reasonably
satisfactory to the Servicing Agent.

          (e)  Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the
Borrower is located, or any treaty to which such jurisdiction is a party, with
respect to payments under this Agreement shall deliver to the Borrower (with a
copy to the Servicing Agent), at the time or times prescribed by applicable law,
such properly completed and executed documentation prescribed by applicable law
or reasonably requested by the Borrower as will permit such payments to be made
without withholding or at a reduced rate.

          (f)  If an Administrative Agent, the Servicing Agent, a Lender or the
Fronting Bank shall become aware that it is entitled to receive a refund in
respect of Indemnified Taxes or Other Taxes for which it shall have received
payment from the Borrower under this Section, it shall promptly notify the
Borrower of the availability of such refund and shall, within 10 days after
receipt of a request by the Borrower, apply for such refund at the Borrower's
expense.  If an Administrative Agent, the Servicing Agent, any Lender or the
Fronting Bank shall receive a refund in respect of any such Indemnified Taxes or
Other Taxes, it shall promptly repay such refund (including any penalties or
interest received with respect thereto) to the Borrower, net of all out-of-
pocket expenses of such Administrative Agent, the Servicing Agent, such Lender
or the Fronting Bank, provided that the Borrower, upon the request of such
Administrative Agent, the Servicing Agent, such Lender or the Fronting Bank,
agrees to return such refund (plus penalties, interest or other charges) to such
Administrative Agent, the Servicing Agent, such Lender or the Fronting Bank in
the event such Administrative Agent, the Servicing Agent, such Lender or the
Fronting Bank shall be required to repay such refund.

          SECTION 2.20.  Duty to Mitigate; Assignment of Commitments Under
Certain Circumstances.  (a)  If any Lender (or Transferee) claims any additional
amounts payable pursuant to Section 2.14 or exercises its rights under Section
2.15 or if the Borrower is required to pay any additional amount to any Lender
or any Governmental Authority for the account of any Lender pursuant to Section
2.19, then such Lender shall use reasonable efforts (consistent with legal and
regulatory restrictions) to file any certificate or document, including, without
limitation, any such certificate or document reasonably requested by the
Borrower, or 

 
                                                                              49

to change the jurisdiction of its Applicable Lending Office or to take other
actions (including the filing of certificates or documents) known to it to be
available if the making of such a filing or change or the taking of such other
action would avoid the need for or reduce the amount of any such additional
amounts which may thereafter accrue or avoid the circumstances giving rise to
such exercise and would not, in the sole determination of such Lender (or
Transferee), be otherwise disadvantageous to such Lender (or Transferee).

          (b)  In the event that any Lender shall have delivered a notice or
certificate pursuant to Section 2.14 or 2.15, or the Borrower shall be required
to make additional payments to any Lender under Section 2.19, the Borrower shall
have the right, at its own expense (which shall include the processing and
recordation fee referred to in Section 10.07(b)), upon notice to such Lender and
the Servicing Agent, to require such Lender to transfer and assign without
recourse (in accordance with and subject to the restrictions contained in
Section 10.07) all its interests, rights and obligations hereunder (other than
any outstanding Competitive Loans held by it) to another financial institution
approved by the Servicing Agent (and, if a Commitment is being assigned, the
Fronting Bank and the Swingline Lender) (which approval shall not be
unreasonably withheld) which shall assume such obligations (which assignee may
be another Lender, if a Lender accepts such assignment); provided, however, that
(i) no such assignment shall conflict with any law, rule or regulation or order
of any Governmental Authority and (ii) the assignee or the Borrower shall pay to
the affected Lender in immediately available funds on the date of such
assignment the outstanding principal of its Loans (other than Competitive Loans)
and participations in LC Disbursements and Swingline Loans, accrued interest
thereon, accrued fees and all other amounts accrued for its account or owed to
it hereunder (including the additional amounts asserted and payable pursuant to
Section 2.14 or 2.19, if any).


                                  ARTICLE III

                         Representations and Warranties

          The Borrower (and, in the case of Section 3.18, MAI) represents and
warrants to the Lenders that:

          SECTION 3.01.  Organization.  Each of the Borrower and its
Subsidiaries is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization, has the requisite power and
authority under its constitutive documents and applicable law to own its
property and assets and to carry on its business as now conducted and is duly
qualified and is in good standing and is authorized to do business in every

 
                                                                              50

jurisdiction where such qualification or authorization is required, except where
the failure so to qualify, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

          SECTION 3.02.  Authorization.  It has the power and authority under
its constitutive documents and applicable law to execute, deliver and carry out
the provisions of this Agreement and to borrow hereunder and all such actions
have been duly and validly authorized by all necessary proceedings on its part
under its constitutive documents and applicable law.

          SECTION 3.03.  Absence of Conflicts.  The execution, delivery and
performance by it of this Agreement, any Borrowings by it hereunder, the
formation of the Joint Venture and the other transactions contemplated hereby
will not (a) violate (i) any provision of the Master Transaction Agreement, the
Limited Partnership Agreement or any other agreement governing its organization
and/or scope of power and authority or (ii) any applicable law, rule, regulation
(including Regulation G, U or X) or order of any Governmental Authority binding
upon it, (b) result in a breach of or constitute (alone or with notice or lapse
of time or both) a material default under any indenture or any material
agreement or other instrument to which it is a party, or by which it or any of
its properties or assets are bound, or (c) result in or require the creation or
imposition of any Lien upon any of its material property or assets.

          SECTION 3.04.  Governmental Approvals.  No registration with or
consent or approval of, or other action by, any Governmental Authority is or
will be required in connection with its execution, delivery or performance of
this Agreement or any Borrowing hereunder, or in connection with the Joint
Venture or the other transactions contemplated hereby, other than any which have
been made or obtained or the failure to obtain, give, file or take which could
not reasonably be expected to result in a Material Adverse Effect.

          SECTION 3.05.  Enforceability.  This Agreement will constitute its
legal, valid and binding obligation, enforceable in accordance with the terms
hereof, except as such enforce  ability may be limited by bankruptcy,
insolvency, reorganization, moratorium or similar laws of general application
from time to time affecting the rights of creditors generally and by general
principles of equity, including implied obligations of good faith and fair
dealing.

          SECTION 3.06.  Financial Statements.  (a)  The Borrower has heretofore
furnished to the Lenders balance sheets, statements of income, invested capital
and cash flows for the respective businesses to be contributed by each of
Lyondell and Millennium to 

 
                                                                              51

the Joint Venture in accordance with the Master Transaction Agreement and the
Asset Contribution Agreements (each a "Contributed Business", and together, the
"Contributed Businesses") (i) as of and for the fiscal year ended December 31,
1996, reported on by independent public accountants (Coopers & Lybrand L.L.P, in
the case of the Lyondell Contributed Business, and Price Waterhouse LLP, in the
case of the Millennium Contributed Business), and (ii) as of and for the fiscal
quarter and the portion of the fiscal year ended June 30, 1997, each certified
by the chief financial officer of Lyondell or Millennium, as the case may be.
Such financial statements present fairly, in all material respects, the
financial position and results of operations and cash flows of each of
Contributed Businesses as of such dates and for such periods in accordance with
GAAP, subject in the case of such quarterly statements to year-end audit
adjustments.

          (b)  The Borrower has heretofore furnished to the Lenders (i) the
unaudited income statement of the Borrower and its Subsidiaries prepared on a
pro forma combined basis for the 12-month period ended December 31, 1996 and for
the six-month period ended June 30, 1997, and (ii) the unaudited balance sheet
of the Borrower and its Subsidiaries prepared on a pro forma combined basis, as
of June 30, 1997.  Such pro forma income statements and balance sheet have been
prepared in good faith based on the assumptions used to prepare the pro forma
financial information contained in the Joint Proxy Statement (which assumptions
are believed by the Borrower on the date hereof to be reasonable), are based on
the best information available to the Borrower as of the date of delivery
thereof, accurately reflect all adjustments required to be made to give effect
to the Joint Venture and present fairly on a pro forma basis the estimated
combined financial position of the Borrower and its Subsidiaries as of June 30,
1997, and the estimated combined results of operations of the Borrower and its
Subsidiaries for the 12-month period ended December 31, 1996 and the six-month
period ended June 30, 1997, assuming that the Joint Venture had been consummated
at such date or at the beginning of each such period, as the case may be.

          (c)  The projections contained in the Confidential Information
Memorandum were prepared in good faith on the basis of the assumptions described
in the Confidential Information Memorandum, which assumptions were believed by
the Borrower in good faith to be reasonable in light of conditions existing at
the time of preparation thereof, and the Borrower has no knowledge of any event
or circumstance that would cause it to change any such assumptions in any
material respect as of the date hereof, it being understood by the
Administrative Agents and the Lenders that actual results may vary from the
projected results set forth therein.

 
                                                                              52

          (d)  Each financial statement delivered pursuant to Section 5.05 (a)
or (b) will, at the time it is delivered, present fairly, in all material
respects, the financial position, results of operations or cash flows, as the
case may be, of the Borrower as of the date or for the period to which it
relates in accordance with GAAP, subject in the case of quarterly statements to
year-end audit adjustments.

          SECTION 3.07.  Material Adverse Effect.  From June 30, 1997, to the
date of this Agreement, there has not occurred any development or event
affecting, or any change in the business, assets, results of operations,
financial condition or prospects of, the Borrower and its Subsidiaries, taken as
a whole, which has had or could reasonably be expected to have a Material
Adverse Effect.

          SECTION 3.08.  Litigation.  There are no actions, suits or proceedings
at law or in equity or by or before any Governmental Authority now pending or,
to its knowledge, threatened against or affecting it or any of its Subsidiaries
or the businesses, assets or rights of it or any of its Subsidiaries as to which
there is a reasonable possibility of an adverse determination and which, if
adversely determined, could, individually or in the aggregate, reasonably be
expected to result in a Material Adverse Effect.

          SECTION 3.09.  Compliance with Laws and Agreements.  (a)  Neither it
nor any of its Subsidiaries is in violation of any law, or in default with
respect to any judgment, writ, injunction, decree, rule or regulation of any
Governmental Authority, where such violation or default could reasonably be
expected to result in a Material Adverse Effect.

          (b)  Neither it nor any of its Subsidiaries is in default under any
provision of any indenture or other agreement or instrument evidencing
Indebtedness, or any other material agreement or instrument to which it is a
party or by which it or any of its properties or assets are or may be bound,
where such default could reasonably be expected to result in a Material Adverse
Effect.

          SECTION 3.10.  Federal Reserve Regulations. (a)  Neither it nor any of
its Subsidiaries is engaged principally, or as one of its important activities,
in the business of extending credit for the purpose of purchasing or carrying
Margin Stock.

          (b)  No part of the proceeds of the Loans has been or will be used,
whether directly or indirectly, and whether immediately, incidentally or
ultimately, for any purpose which entails a violation of the provisions of the
Regulations of the 

 
                                                                              53

Board, including, without limitation, Regulation G, U or X thereof. After giving
effect to each Credit Event and the application of the proceeds thereof, not
more than 25% of the value, determined in accordance with Regulation U, of the
assets subject to Section 6.01 will consist of Margin Stock.

          SECTION 3.11.  Tax Returns.  All Federal, state, local and foreign tax
returns which to its knowledge are required to have been filed by or on behalf
of the Borrower and its Subsidiaries, or by Lyondell or Millennium or their
subsidiaries, with respect to the assets or operations of the Borrower and its
Subsidiaries, have been filed, and all taxes shown to be due and payable on such
returns or on any assessments received by the Borrower and its Subsidiaries (or
by Lyondell or Millennium or their subsidiaries) have been paid, except where
the failure to do so could not reasonably be expected to result in a Material
Adverse Effect.

          SECTION 3.12.  Employee Benefit Plans.  (a)  It and its ERISA
Affiliates are in compliance in all material respects with those provisions of
ERISA and the regulations and published interpretations thereunder which are
applicable to it, except where noncompliance could not reasonably be expected to
result in a Material Adverse Effect.  No Reportable Event has occurred with
respect to any Plan that could reasonably be expected to result in a Material
Adverse Effect, and no unfunded liabilities exist under all of the Plans in the
aggregate that could reasonably be expected to result in a Material Adverse
Effect.

          (b)  Neither it nor any ERISA Affiliate has incurred any Withdrawal
Liability that materially and adversely affects the financial condition of it
and its Subsidiaries taken as a whole or that materially and adversely impairs
its ability to perform its obligations under this Agreement or any other Loan
Document.  Neither it nor any ERISA Affiliate has received any notification that
any Multiemployer Plan is in reorganization or has been terminated within the
meaning of Title IV of ERISA, and no Multiemployer Plan is reasonably expected
to be in reorganization or to be terminated, where such reorganization or
termination has resulted or is likely to result in an increase in the
contributions required to be made to such Multiemployer Plan that could
reasonably be expected to result in a Material Adverse Effect.

          SECTION 3.13. Accuracy of Information.  (a)  No information, report,
exhibit or schedule furnished by or on behalf of it to the Administrative Agents
or any Lender in connection with the negotiation of this Agreement or included
herein contained or contains any material misstatement of fact or omitted or
omits to state any material fact necessary to make the statements 

 
                                                                              54

therein, in the light of the circumstances under which they were made, not
misleading.

          (b)  The representations and warranties set forth in the Master
Transaction Agreement and the Asset Contribution Agreements are and will be true
and correct in all material respects on and as of the date hereof and on and as
of the Effective Date, except to the extent that (i) the accuracy of any thereof
has been waived by the party or parties to such agreements for whose benefit the
same shall have been made and (ii) the event or circumstance necessitating such
waiver could not reasonably be expected to result in a Material Adverse Effect.

          SECTION 3.14.  Investment Company Act; Public Utility Holding Company
Act.  Neither it nor any of its Subsidiaries is an "investment company" as
defined in, or is otherwise subject to regulation under, the Investment Company
Act of 1940.  Neither it nor any of its Subsidiaries is subject to regulation as
a "holding company" under the Public Utility Holding Company Act of 1935.

          SECTION 3.15.  Environmental and Safety Matters.  It and each of its
Subsidiaries and the businesses conducted by them have complied in all material
respects with all Federal, state, local and other statutes, ordinances, orders,
judgments, rulings and regulations relating to the environment or to protection
of the environment or to employee health and safety ("Environmental and Safety
Laws") except for violations that either alone or in the aggregate could not
reasonably be expected to result in a Material Adverse Effect.  Neither it nor
any of its Subsidiaries manages or handles any hazardous wastes, hazardous
substances, hazardous materials, toxic substances or toxic pollutants regulated
by Environmental and Safety Laws in violation of such Environmental and Safety
Laws where such violation could reasonably be expected to result, individually
or together with other violations, in a Material Adverse Effect.  To the best of
its knowledge, neither it nor any of its Subsidiaries has any liabilities or
contingent liabilities relating to environmental or employee health and safety
matters which, individually or in the aggregate, could reasonably be expected to
result in a Material Adverse Effect.

          SECTION 3.16.  Title to Properties.  It and each of its Material
Subsidiaries has good and, in the case of real property, marketable title to, or
valid leasehold interests in or other rights to use, all its material assets and
properties (including, on the Effective Date, all the assets and properties
referred to in the Joint Proxy Statement as being transferred to or owned by
it), except for such assets and properties as are no longer being used or useful
in the conduct of its businesses or have been disposed of in the ordinary course
of business and except for defects in title and exceptions to leasehold
interests that either 

 
                                                                              55

alone or in the aggregate could not reasonably be expected to result in a
Material Adverse Effect. All such material assets and properties are free and
clear of all mortgages, pledges, liens, charges, security interests and other
encumbrances other than those permitted by Section 6.01.

          SECTION 3.17.  Senior Ranking.  The Obligations will rank equally with
all of its senior, unsecured indebtedness, whether now existing or hereafter
created.

          SECTION 3.18.  Representations of MAI.  (a) MAI is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization.  MAI has the corporate power and authority to execute and deliver
this Agreement and to carry out the provisions of Article IX hereof, and all
such actions have been duly and validly authorized by all necessary corporate
proceedings on its part.  The execution and delivery by MAI of this Agreement
and the performance of its obligations hereunder will not (a) violate (i) any
provision of its certificate of incorporation or by-laws or (ii) any applicable
law, rule, regulation or order of any Governmental Authority binding upon it,
(b) result in a breach of or constitute (alone or with notice or lapse of time
or both) a material default under any indenture, agreement or other instrument
to which it is a party, or by which it or any of its properties or assets are
bound, or (c) result in or require the creation or imposition of any Lien upon
any of its material property or assets.  No registration with or consent or
approval of, or other action by, any Governmental Authority is or will be
required in connection with MAI's execution or delivery of this Agreement or the
performance of its obligations under Article IX hereof, other than any which
have been made or obtained or the failure to obtain, give, file or take which
could not reasonably be expected to result in a Material Adverse Effect.



                                   ARTICLE IV

                             Conditions of Lending

          (b)  Except in the case of Borrowings that do not increase the
     aggregate principal amount of the Loans of any Lender outstanding, the
     representations and warranties set forth in Article III shall be true and
     correct in all material respects on and as of the date of such Credit Event
     with the same effect as though made on and as of such date, except to the
     extent such representations and warranties expressly relate to an earlier
     date.

          (c)  At the time of and immediately after such Credit Event, no Event
     of Default or Default shall have occurred and be continuing.

Each Credit Event shall be deemed to constitute a representation and warranty on
the date of such Credit Event as to the matters specified in paragraphs (b) and
(c) of this Section.

          SECTION 4.02.  Effective Date.  The obligations of the Lenders and the

may be merged into the Borrower or a Subsidiary in a transaction in which the
surviving person is the Borrower or a wholly owned Subsidiary and, in the case
of any transaction in which the consideration (other than equity interests of

ended fiscal quarter, the Borrower has submitted to the Administrative Agents
calculations reasonably satisfactory to the Administrative Agents showing pro
forma compliance with the covenants in Sections 6.04 and 6.05 assuming that such
transaction had occurred at the most recent fiscal quarter end for which

consolidated financial information demonstrating compliance with the covenants
set forth in Sections 6.04 and 6.05 as of the most recent fiscal quarter end and

customary restrictions and conditions contained in (i) any agreement relating to
the sale of a Material Subsidiary, or all or substantially all of its assets,
pending such sale or (ii) any agreement relating to secured Indebtedness
permitted by this Agreement, if such restrictions or conditions apply only to

          (e) the Borrower or any Material Subsidiary shall (i) voluntarily
     commence any proceeding or file any petition seeking relief under Title 11

          (f) an involuntary proceeding shall be commenced or an involuntary
     petition shall be filed in a court of competent jurisdiction seeking (i)
     relief in respect of the Borrower or any Material Subsidiary or of a

     any period of grace specified in the instrument evidencing or governing
     such Indebtedness); or (iii) without limiting the rights of the Lenders
     under clauses (g)(i) and (g)(ii) above, the Borrower or any Subsidiary
     shall default in the payment of principal of any Indebtedness, which
     principal, individually or in the aggregate with other defaulted principal,
     shall be in excess of $15,000,000, when due and payable (after giving

     not have been rescinded or annulled, or such accelerated Indebtedness shall
     not have been discharged, within five Business Days of such acceleration;

          (h) (A) a Reportable Event or Reportable Events, or a failure to make

     trustee shall be appointed by a United States District Court to administer

     required to be paid by the Borrower and its ERISA Affiliates to

     the sponsor of a Multiemployer Plan that such Multiemployer Plan is in
     reorganization or is being terminated, within the meaning of Title IV of
     ERISA, if solely as a result of such reorganization or termination the
     aggregate annual contributions of the Borrower and its ERISA Affiliates to
     all Multiemployer Plans that are then in reorganization or have been or are
     being terminated have been or will be increased could reasonably be
     expected to result in a Material Adverse Effect;

          (k) one or more judgments for the payment of money (not reimbursed by
     insurance policies of the Borrower or any Subsidiary) in excess of
     $20,000,000 in the aggregate shall be rendered by a court or other tribunal
     against the Borrower or any Subsidiary and shall remain undischarged for a
     period of 30 consecutive days during which the execution of such judgments
     shall not have been stayed effectively or any action shall be legally taken
     by a judgment creditor to levy upon assets or properties of the Borrower or
     any Subsidiary to enforce any such judgment; or

          (l) a Change in Control shall occur;

described in paragraph (e) or (f) above), and at any time thereafter during the

direction of the Required Lenders shall, by written or telecopied notice to the
Borrower, take either or both of the following actions, at the same or different
times:  (i) terminate forthwith the Commitments, 

 
                                                                              72

(ii) demand cash collateral as provided in Section 2.07(j) and (iii) declare the
Loans then outstanding to be forth with due and payable, whereupon the principal
of the Loans so declared due and payable, together with accrued interest and any
unpaid accrued Fees and all other liabilities of the Borrower accrued hereunder,
shall become forthwith due and payable both as to principal and interest,
without presentment, demand, protest or any other notice of any kind, all of
which are hereby expressly waived by the Borrower, anything contained herein to
the contrary notwithstanding; provided, however, that, in the event of a default
with respect to the Borrower described in paragraph (e) or (f) above, the
Commitments shall automatically terminate, the deposit of cash collateral as
provided in Section 2.07(j) shall automatically be required and the principal of
the Loans then outstanding, together with accrued interest thereon and any
unpaid accrued Fees and all other liabilities of the Borrower accrued hereunder,
shall automatically become due and payable, without presentment, demand, protest
or notice of any kind, all of which are hereby expressly waived by the Borrower,
anything contained herein to the contrary notwithstanding.


                                  ARTICLE VIII

                             Administrative Agents

          Each of the Lenders and the Fronting Bank irrevocably authorizes the
Administrative Agents (and for purposes of this Article VIII, the term
"Administrative Agent" or "Administrative Agents" shall include BofA in its
capacity as Servicing Agent, as applicable) to take such action on its behalf
and to exercise such powers hereunder as are specifically delegated to the
Administrative Agents by the terms hereof together with such powers as are
reasonably incidental thereto.  Each of the Administrative Agents may perform
any and all its duties and exercise its rights and powers by or through any one
or more sub-agents selected and appointed by such Administrative Agent.  Each of
the Administrative Agents and any such sub-agent may perform any and all its
duties and exercise its rights and powers through Affiliates or its or its
Affiliates' employees.  The exculpatory provisions of the following paragraphs
shall apply to any such sub-agent, to the Affiliates of the Administrative
Agents and any such sub-agent and to the directors, officers and employees of
the Administrative Agents, any such sub-agent and their respective Affiliates.

          The Administrative Agents are hereby expressly authorized and directed
by the Lenders to the extent provided in this Agreement, without hereby limiting
any implied authority, (a) to receive on behalf of the Lenders all payments of
principal of and interest on the Loans and all other amounts due to the 

 
                                                                              73

Lenders hereunder, and promptly to distribute to each Lender its proper share of
each payment so received; (b) to give notice on behalf of each of the Lenders to
the Borrower of any Event of Default specified in this Agreement of which the
Administrative Agents have actual knowledge acquired in connection with its
agency hereunder; and (c) to distribute to each Lender copies of all notices,
financial statements and other materials delivered by the Borrower pursuant to
this Agreement as received by the Administrative Agents.

          Neither the Administrative Agents nor any of their directors,
officers, employees or agents shall be liable as such for any action taken or
omitted to be taken by it or them hereunder or in connection herewith (a) at the
request or with the approval of the Required Lenders (or, if otherwise
specifically required hereunder, the consent of all the Lenders) or (b) in the
absence of its or their own gross negligence or wilful misconduct. Each Lender
acknowledges that it has decided to enter into this Agreement and to extend the
Loans hereunder based on its own analysis of the creditworthiness of the
Borrower and agrees that the Administrative Agents shall bear no responsibility
for such creditworthiness.

          The Administrative Agents shall not be responsible in any manner to
any of the Lenders for the effectiveness, enforceability, genuineness, validity
or due execution of this Agreement or any other agreements or certificates,
requests, financial statements, notices or opinions of counsel or for any
recitals, statements, warranties or representations contained herein or in any
such instrument or be under any obligation to ascertain or inquire as to the
performance or observance of any of the terms, provisions, covenants,
conditions, agreements or obligations of this Agreement or any other agreements
on the part of the Borrower and, without limiting the generality of the
foregoing, the Administrative Agents shall, in the absence of knowledge to the
contrary, be entitled to accept any certificate furnished pursuant to this
Agreement as conclusive evidence of the facts stated therein and shall be
entitled to rely on any note, notice, consent, certificate, affidavit, letter,
telegram, teletype or telecopy message, statement, order or other document which
it reasonably believes to be genuine and correct and to have been signed or sent
by the proper person or persons.  It is understood and agreed that each of the
Administrative Agents may exercise its rights and powers under other agreements
and instruments to which it is or may be a party and engage in other
transactions with the Borrower or any Subsidiary or other Affiliate as though it
were not the agent of the Lenders hereunder.

          The Administrative Agents may consult with legal counsel selected by
them in connection with matters arising under this Agreement and any action
taken or suffered in good faith by 

 
                                                                              74

either of them in accordance with the opinion of such counsel shall be full
justification and protection to it. Each of the Administrative Agents may
exercise any of its powers and rights and perform any duty under this Agreement
through agents or attorneys.

          The Lenders shall, in accordance with their Pro Rata Percentages at
the time of demand for indemnification hereunder, indemnify each of the
Administrative Agents, in its capacity as agent on behalf of the Lenders (to the
extent not reimbursed by the Borrower pursuant to the terms hereof and without
limiting the obligations of the Borrower to do so) against any cost, expense
(including reasonable counsel fees and disbursements), claim, demand, action,
loss or liability (except such as results from such Administrative Agent's gross
negligence or wilful misconduct) that such Administrative Agent may suffer or
incur in connection with this Agreement or any action taken or omitted by it
hereunder.

          Subject to the appointment and acceptance of a successor
Administrative Agent as provided below, the Administrative Agents may resign at
any time by notifying the Lenders, the Fronting Bank and the Borrower.  Upon any
such resignation, the Required Lenders shall have the right to appoint a
successor Administrative Agent; provided that if only one Administrative Agent
resigns, the remaining Administrative Agent automatically shall be deemed to
have been appointed as, and have accepted the position of, successor to the
resigning Administrative Agent.  If no successor Administrative Agent shall have
been so appointed by the Required Lenders and shall have accepted such
appointment within 30 days after the retiring Administrative Agents give notice
of resignation, then the retiring Administrative Agents may, on behalf of the
Lenders, appoint a successor Administrative Agent which shall be a bank having
an office (or an Affiliate with an office) in New York, New York, with a
combined capital and surplus of at least $500,000,000.  Upon the acceptance of
any appointment as Administrative Agent hereunder by a successor bank, or upon
the deemed appointment of one of the Administrative Agent or Agents as successor
to the other, such successor shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agents and each of the retiring Administrative Agents shall be discharged from
its duties and obligations hereunder.  After any Administrative Agent's
resignation hereunder, the provisions of this Article shall continue in effect
for its benefit in respect of any actions taken or omitted to be taken by it
while it was acting as Administrative Agent.

          The Lenders hereby acknowledge that the Administrative Agents shall
not be under any duty to take any discretionary 

 
                                                                              75

action permitted to be taken by them pursuant to the provisions of this
Agreement unless they shall be requested in writing to do so by the Required
Lenders or, where required, all the Lenders.


                                   ARTICLE IX

                                   Guarantee

          In order to induce the Lenders to extend credit hereunder, MAI hereby
irrevocably and unconditionally guarantees, on the terms and subject to the
limitations set forth in this Article, the Borrower's obligations in respect of
up to $750,000,000 principal amount of the Loans and LC Disbursements
outstanding at any time together with all interest accrued and unpaid thereon
(such obligations being called the "Guaranteed Obligations"), which guarantee of
MAI will remain in effect as long as any Guaranteed Obligations remain
outstanding.

          Notwithstanding any other provision of this Article, MAI is executing
this Agreement as a secondary rather than as a primary obligor, and the
guarantee of MAI hereunder shall be a guarantee of collection rather than of
payment when and as due, it being agreed that MAI shall be obligated to pay the
Guaranteed Obligations only after the Lenders shall have pursued their other
remedies to compel payment of such Guaranteed Obligations by the Borrower and
after exhaustion of all available remedies, including without limitation, the
liquidation of assets, payment cannot be obtained from the Borrower.

          The obligations of MAI hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, and shall not
be subject to any defense or setoff, counterclaim, recoupment or termination
whatsoever, by reason of the invalidity, illegality or unenforceability of the
Guaranteed Obligations, any impossibility in the performance of the Guaranteed
Obligations or otherwise.  Without limiting the generality of the foregoing, the
obligations of MAI hereunder shall not be discharged or impaired or otherwise
affected by the failure of the Administrative Agents or any Lender to assert any
claim or demand or to enforce any remedy under this Agreement or under any other
agreement, by any waiver or modification of any of the Guaranteed Obligations,
by any default, failure or delay, wilful or otherwise, in the performance of the
Guaranteed Obligations, or by any other act or omission which may or might in
any manner or to any extent vary the risk of MAI or otherwise operate as a
discharge of MAI as a matter of law or equity.

          MAI further agrees that its obligations hereunder shall continue to be
effective or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any Guaranteed 

 
                                                                              76

Obligation is rescinded or must otherwise be restored by the Administrative
Agents, the Servicing Agent, the Fronting Bank or any Lender upon the bankruptcy
or reorganization of the Borrower or otherwise, unless those obligations of MAI
have otherwise been terminated in accordance with the terms of this Agreement.

          Upon payment by MAI of any Guaranteed Obligations, each Lender shall,
in a reasonable manner, assign to MAI the amount of the Guaranteed Obligations
owed to it and so paid, such assignment to be pro tanto to the extent to which
the Guaranteed Obligations in question were discharged by MAI, or make such
disposition thereof as MAI shall direct (all without recourse to and without any
representation or warranty by any Lender).

          Upon payment by MAI of any sums as provided above, all rights of MAI
against the Borrower arising as a result thereof by way of right of subrogation
or otherwise shall in all respects be subordinate and junior in right of payment
to the prior indefeasible payment in full of all the Guaranteed Obligations to
the Lenders.

               Attention of David Mills

          All notices and other communications given to any party hereto in
accordance with the provisions of this Agreement shall be deemed to have been
given on the date of receipt if delivered by hand or overnight courier service
or sent by telecopy equipment of the sender, or on the date five Business Days
after dispatch by certified or registered mail if mailed, in each case
delivered, sent or mailed (properly addressed) to such party as provided in this
Section 10.01 or in accordance with the latest unrevoked direction from such
party given in accordance with this Section 10.01.

 
                                                                              78

          SECTION 10.02.  No Waivers; Amendments.  (a)  No failure or delay of
the Administrative Agents, the Servicing Agent, the Fronting Bank or any Lender
in exercising any power or right hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power.  The rights and remedies of the Administrative Agents, the
Servicing Agent, the Fronting Bank and the Lenders hereunder are cumulative and
not exclusive of any rights or remedies which they would otherwise have.  Except
as may be otherwise expressly provided herein, no waiver of any provision of
this Agreement nor any consent to any departure by the Borrower therefrom shall
in any event be effective unless the same shall be in writing and signed by the
Required Lenders (unless otherwise specified herein), and then such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given.  No notice or demand on the Borrower in any case shall entitle the
Borrower to any other or further notice or demand in similar or other
circumstances.  Without limiting the generality of the foregoing, the making of
a Loan or issuance of a Letter of Credit shall not be construed as a waiver of
any Default, regardless of whether the Administrative Agents, the Servicing
Agent, any Lender or the Fronting Bank may have had notice or knowledge of such
Default at the time.

          (b)  Neither this Agreement or any Exhibit or Schedule hereto may be
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and by the Required Lenders; provided, however,
that no such agreement shall (i) change the Commitment of any Lender without the
prior written consent of such Lender, (ii) postpone the scheduled date of
payment of the principal amount of any Loan or LC Disbursement, or any interest
thereon, or any Fee payable hereunder, or reduce the amount of, waive or excuse
any such payment, or postpone the scheduled date of expiration of any
Commitment, without the written consent of each Lender affected thereby, (iii)
amend or modify or otherwise affect the rights or duties of the Administrative
Agents, the Servicing Agent, the Fronting Bank or the Swingline Lender without
the prior written consent of the Administrative Agents, the Servicing Agent, the
Fronting Bank or the Swingline Lender, as the case may be, or (iv) amend or
modify the definition of "Required Lenders", Section 2.17, this Section 10.02 or
Section 10.07, without the prior written consent of each Lender.

          (c)  Notwithstanding any other provision of this Agreement, MAI may
terminate its guarantee under Article IX at any time that it may do so under
Section 8.6(c) of the Limited 

 
                                                                              79

Partnership Agreement (as Section 8.6(c) is in effect on the date hereof or as
such Section is hereafter amended with the consent of the Required Lenders);
provided, however, that no such termination shall be effective to the extent of
the amount of any Guaranteed Obligations with respect to which an Event of
Default under Article VII (b) or (c) has occurred and is continuing at the time
that those conditions have been satisfied until such amount has been paid in
full, together with all accrued and unpaid interest thereon (it being expressly
understood that under certain circumstances MAI's guarantee under Article IX may
be effectively terminated by MAI as to all Guaranteed Obligations upon
satisfaction of such Section 8.6(c) conditions even though an Event of Default
may have occurred and be continuing).

          SECTION 10.03.  Payments.  Except as otherwise provided in this
Agreement, all payments to be made by the Borrower to the Lenders hereunder
shall be made to the Servicing Agent in immediately available funds at Bank of
America National Trust and Savings Association (ABA #121000358, Account #12339-
15888 and Reference: Equistar) not later than 11:00 a.m., New York City time, on
the date due.  Funds received after the applicable time shall be deemed to have
been received by the Lenders on the following Business Day.

          Unless otherwise provided herein, if any payment of principal,
interest or any other amount payable by the Borrower hereunder shall fall due on
a day that is not a Business Day, then such due date shall be extended to the
next succeeding Business Day, and such extension of time shall be included in
computing interest, if any, in connection with such payment.

          Upon receipt of any payment for the accounts of the Lenders hereunder,
the Servicing Agent will promptly distribute to each Lender its share of such
payment.

          SECTION 10.04.  Governing Law; Submission to Jurisdiction.  (a)  THIS
AGREEMENT SHALL BE CONSTRUED AND INTERPRETED IN ACCORDANCE WITH AND GOVERNED BY
THE LAWS OF THE STATE OF NEW YORK.

          (b)  To the extent it may effectively do so under applicable law, each
of the Borrower and MAI irrevocably (i) submits to the nonexclusive jurisdiction
of any New York State or Federal court sitting in the Borough of Manhattan, The
City of New York, over any suit, action or proceeding arising out of or relating
to this Agreement or any other document contemplated hereby, irrevocably waives
and (ii) agrees not to assert, by way of motion, as a defense or otherwise, any
claim that it is not subject to the jurisdiction of any such court, any
objection that it may now or hereafter have to the laying of the venue of any
such suit, action or proceeding brought in any such court and any 

 
                                                                              80

claim that any such suit, action or proceeding brought in any such court has
been brought in an inconvenient forum.

          (c)  Each of the Borrower and MAI agrees, to the fullest extent it may
effectively do so under applicable law, that a judgment in any suit, action or
proceeding of the nature referred to in paragraph (b) above brought in any such
court shall be conclusive and binding upon the Borrower or MAI, as the case may
be, and may be enforced in the courts of the United States of America or the
State of New York (or any other courts to the jurisdiction of which the Borrower
or MAI, as the case may be, is or may be subject) by a suit upon such judgment.

          (d)  To the extent it may effectively do so under applicable law, each
of the Borrower and MAI consents to process being served in any suit, action or
proceeding of the nature referred to in paragraph (b) by mailing a copy thereof
by registered or certified mail, postage prepaid, return receipt requested, to
the address of the Borrower or MAI, as the case may be, as set forth or referred
to in Section 10.01.  To the extent it may effectively do so under applicable
law, each of the Borrower and MAI agrees that such service (i) shall be deemed
in every respect effective service of process upon the Borrower or MAI, as the
case may be, in any such suit, action or proceeding and (ii) shall be taken and
held to be valid personal service upon and personal delivery to the Borrower or
MAI, as the case may be.

          (e)  Nothing in this Section 10.04 shall affect the right of the
Administrative Agents, the Servicing Agent or any Lender to serve process in any
manner permitted by law, or limit any right that the Administrative Agents, the
Servicing Agent or any Lender may have to bring proceedings against the Borrower
or MAI, as the case may be, in the courts of any jurisdiction or to enforce in
any lawful manner a judgment obtained in one jurisdiction in any other
jurisdiction.

          SECTION 10.05.  Expenses; Documentary Taxes; Indemnity.  (a)  The
Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the
Administrative Agents, the Servicing Agent, the Fronting Bank and their
respective Affiliates, including the reasonable fees, charges and disbursements
of counsel for the Administrative Agents, in connection with the syndication of
the credit facilities provided for herein, the preparation and administration of
this Agreement or any amendments, modifications or waivers of the provisions
hereof (whether or not the transactions contemplated hereby or thereby shall be
consummated), (ii) all reasonable out-of-pocket expenses incurred by the
Fronting Bank in connection with the issuance, amendment, renewal or extension
of any Letter of Credit or any demand for payment thereunder and (iii) all out-
of-pocket expenses incurred by the Administrative Agents, the Servicing Agent,
the 

 
                                                                              81

Fronting Bank or any Lender, including the fees, charges and disbursements of
any counsel for the Administrative Agents, the Servicing Agent, the Fronting
Bank or any Lender, in connection with the enforcement or protection of its
rights in connection with this Agreement, including its rights under this
Section, or in connection with the Loans made or Letters of Credit issued
hereunder, including all such out-of-pocket expenses incurred during any workout
or restructuring in respect of such Loans or Letters of Credit.

          (b)  The Borrower shall indemnify the Administrative Agents, the
Servicing Agent, the Fronting Bank and each Lender, and each Related Party of
any of the foregoing Persons (each such Person being called an "Indemnitee")
against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, including the fees, charges and
disbursements of any counsel for any Indemnitee, incurred by or asserted against
any Indemnitee arising out of, in connection with, or as a result of any actual
or threatened claim, litigation, investigation or proceeding, whether based on
contract, tort or any other theory and regardless of whether any Indemnitee is a
party thereto, relating to (i) the execution or delivery of this Agreement or
any agreement or instrument contemplated hereby, the performance by the parties
hereto of their respective obligations hereunder or the consummation of the
transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use
of the proceeds therefrom (including any refusal by the Fronting Bank to honor a
demand for payment under a Letter of Credit if the documents presented in
connection with such demand do not strictly comply with the terms of such Letter
of Credit), or (iii) any actual or alleged presence or release of Hazardous
Materials on or from any property owned or operated by the Borrower or any of
its Subsidiaries, or any Environmental Liability related in any way to the
Borrower or any of its Subsidiaries; provided that such indemnity shall not, as
to any Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses resulted from the gross negligence or wilful
misconduct of such Indemnitee.

          (c)  The provisions of this Section 10.05 shall remain operative and
in full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement, or any investigation made by or on behalf of the
Lenders or the Administrative Agents.  All amounts due under this Section 10.05
shall be payable on written demand therefor.

          SECTION 10.06.  Survival of Agreements, Representations and
Warranties, etc.  All warranties, representations and covenants made by the
Borrower herein or in any certificate or 

 
                                                                              82

other instrument delivered by the Borrower or on its behalf in connection with
this Agreement shall be considered to have been relied upon by the Lenders and
shall survive the making of the Loans and issuance of any Letters of Credit
herein contemplated regardless of any investigation made by the Lenders, the
Administrative Agents or the Servicing Agent or on their behalf and shall
continue in full force and effect so long as any amount due or to become due
hereunder is outstanding and unpaid. The right of each Lender to receive
payments pursuant to Sections 2.14, 2.16 and 2.19 shall survive the termination
of this Agreement and the repayment of the Loans.

          SECTION 10.07.  Successors and Assigns.  (a)  This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns (including any Affiliate of the Fronting Bank that issues
any Letter of Credit).  The Borrower may not assign or transfer any of its
rights or obligations hereunder without the prior written consent of all the
Lenders.

          (b)  Each Lender may assign all or a portion of its interests, rights
and obligations under this Agreement (including all or a portion of its
Commitment (and the Loans at the time owing to it)); provided, however, that (i)
except in the case of an assignment by a Lender to an Affiliate of such Lender
or to another Lender, the Borrower and the Servicing Agent (and, in the case of
an assignment of all or a portion of a Commitment or any Lender's obligations in
respect of its LC Exposure or Swingline Exposure, the Fronting Bank and the
Swingline Lender) must consent to such assignment in writing (which consent may
not be unreasonably withheld), (ii) each such assignment shall be of a constant,
and not a varying, percentage of all the assigning Lender's rights and
obligations under this Agreement, (iii) except in the case of an assignment to
another Lender or in the case of an assignment of the assigning Lender's total
Commitment, the aggregate amount of the Commitment of the assigning Lender
subject to any such assignment shall not be less than $10,000,000 (or any other
smaller amount agreed upon by the Administrative Agents and the Borrower, and
(iv) the parties to each such assignment shall execute and deliver to the
Servicing Agent for its acceptance and recording in the Register an Assignment
and Acceptance, together with a processing and recordation fee of $3,500; and
provided, further, that any consent of the Borrower otherwise required under
this paragraph shall not be required if an Event of Default under paragraph (e)
or (f) of Article VII has occurred and is continuing.  Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment and Acceptance, which effective date shall be (unless waived
by the Servicing Agent) at least five Business Days after the execution thereof,
(A) the assignee thereunder shall be a party hereto, and, to the extent of the
interest assigned by such Assignment and Acceptance, have the rights and
obligations of a Lender under this Agreement, and (B) the assignor thereunder

 
                                                                              83

shall, to the extent of the interest assigned by such Assignment and Acceptance,
be released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of the
assignor's rights and obligations under this Agreement, the assignor shall cease
to be a party hereto but shall continue to be entitled to the benefits of
Sections 2.14, 2.16 and 10.05 as well as to any interest and Facility Fee
accrued for its account hereunder and not yet paid).  Notwithstanding the
foregoing, any Lender assigning its rights and obligations under this Agreement
may retain any Competitive Loans made by it outstanding at such time, and in
such case shall retain its rights hereunder in respect of any Loans so retained
until such Loans have been repaid in full in accordance with this Agreement.

          (c)  By executing and delivering an Assignment and Acceptance, the
assignor and the assignee thereunder shall be deemed to confirm to and agree
with each other and the Borrower as follows:  (i) such assignor warrants that it
is the legal and beneficial owner of the interest being assigned free and clear
of any adverse claim; (ii) except as set forth in clause (i) above, the assignor
makes no other representation or warranty and assumes no responsibility with
respect to any statements, warranties or representations made in or in
connection with this Agreement or any other instrument or document furnished
pursuant hereto or thereto, or the execution, legality, validity, enforce
ability, genuineness, sufficiency or value of this Agreement, or any other
instrument or document furnished pursuant hereto or thereto, or the financial
condition of the Borrower or the performance or observance by the Borrower of
any of its Obligations under this Agreement or any other instrument or
document furnished pursuant hereto or thereto; (iii) such assignee represents
and warrants that it is legally authorized to enter into such Assignment and
Acceptance; (iv) such assignee confirms that it has received a copy of this
Agreement, together with copies of the financial statements described in Section
3.06 or the most recent financial statements delivered pursuant to Section 5.05,
as applicable, and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (v) such assignee will independently and without
reliance upon the assignor 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 action under this Agreement; (vi) such assignee appoints
and authorizes the Administrative Agents and the Servicing Agent to take such
action as agent on its behalf and to exercise such powers under this Agreement,
as are delegated to the Administrative Agents and the Servicing Agent by the
terms hereof, together with such powers as are reasonably incidental thereto;
and (vii) such assignee agrees that it will, to the extent of the interest
assigned to it, perform in accordance with their terms all the obligations which
by the terms of this Agreement are required to be performed by the Lenders.

 
                                                                              84

          (d)  The Borrower agrees that each Lender may without the consent of
the Borrower, the Servicing Agent, the Fronting Bank or the Swingline Lender
sell participations to one or more banks or other entities in all or a portion
of its rights and obligations under this Agreement (including, without
limitation, all or a portion of its Commitment and the same portion of the Loans
owing to it) and the Borrower agrees that any purchaser of a participation in
such Loans so acquired may exercise any and all rights of banker's lien, setoff,
counterclaim or otherwise with respect to any and all moneys owing by the
Borrower to such purchaser as fully as if such purchaser were a Lender acquiring
such Loans hereunder in the amount of such participation; provided, however,
that (i) such selling Lender's obligations under this Agreement shall remain
unchanged, (ii) such Lender shall remain solely responsible to the Borrower for
the performance of its obligations hereunder, (iii) the participating lenders
or other entities shall be entitled to the benefit of the cost protection
provisions contained in Sections 2.14, 2.16 and 2.19 to the same extent as if
they were such Lender (but the amount claimed by any participating lender or
other entity shall not exceed the amount that could have been claimed by the
Lender from which it acquired its participation) and (iv) the Borrower, the
Administrative Agents, the Fronting Bank and the other Lenders shall continue to
deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement, and such Lender shall retain the
sole right to enforce the obligations of the Borrower relating to the Loans and
to approve, without the consent of or consultation with any participant, any
amendment, modification or waiver of any provision of this Agreement (other than
amendments, modifications or waivers with respect to Fees payable hereunder or
an increase in the amount of principal of or a decrease in the rate at which
interest is payable on the Loans, or an extension of the dates fixed for
payments of principal of or interest on the Loans or payments of Fees).

          (e)  Any Lender may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
10.07, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower or the Subsidiaries
furnished to the Lenders (including pursuant to Section 5.08) by or on behalf of
the Borrower or the Subsidiaries, as applicable; provided that, prior to any
such disclosure, each such assignee or participant or proposed assignee or
participant shall execute an agreement whereby such assignee or participant
shall agree (subject to customary exceptions) to preserve the confidentiality of
any confidential information relating to the Borrower or any Subsidiary received
from the Lenders.

 
                                                                              85

          (f)  The Servicing Agent shall maintain at one of its offices in The
City of New York a copy of each Assignment and Acceptance delivered to it and a
register for the recordation of the names and addresses of the Lenders and the
Commitment of, and the principal amount of the Loans and LC Disbursements owing
to, each Lender pursuant to the terms hereof (the "Register").  The entries in
the Register shall be conclusive in the absence of manifest error and the
Borrower, the Administrative Agents, the Servicing Agent, the Fronting Bank and
the Lenders may treat each person whose name is recorded in the Register
pursuant to the terms hereof as a Lender hereunder for all purposes of this
Agreement.  The Register shall be available for inspection by the Borrower at
any reasonable time and from time to time upon reasonable prior notice.

          (g)  Any Lender may at any time pledge all or any portion of its
rights under this Agreement to a Federal Reserve Bank; provided that no such
pledge shall release any Lender from its obligations hereunder or substitute any
such Federal Reserve Bank for such Lender as a party hereto.

          (h)  Notwithstanding anything to the contrary contained herein, any
Lender (a "Granting Bank") may grant to a special purpose funding vehicle (an
"SPC") of such Granting Bank, identified as such in writing from time to time by
the Granting Bank to the Administrative Agents and the Borrower, the option to
provide to the Borrower all or any part of any Loan that such Granting Bank
would otherwise be obligated to make to the Borrower pursuant to Section 2.02,
provided that (i) nothing herein shall constitute a commitment to make any Loan
by any SPC and (ii) if an SPC elects not to exercise such option or otherwise
fails to provide all or any part of such Loan, the Granting Bank shall be
obligated to make such Loan pursuant to the terms hereof.  The making of a Loan
by an SPC hereunder shall be deemed to utilize the Commitments of all the
Lenders to the same extent, and as if, such Loan were made by the Granting Bank.
Each party hereto hereby agrees that no SPC shall be liable for any payment
under this Agreement for which a Lender would otherwise be liable, for so long
as, and to the extent, the related Granting Bank makes such payment.  In
furtherance of the foregoing, each party hereto hereby agrees that, prior to the
date that is one year and one day after the payment in full of all outstanding
senior indebtedness of any SPC, it will not institute against, or join any other
person in instituting against, such SPC any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings or similar proceedings under
the laws of the United States or any State thereof.  In addition,
notwithstanding anything to the contrary contained in this Section 10.07, any
SPC may assign all 

 
                                                                              86

or a portion of its interests in any Loans to its Granting Bank or to any
financial institutions providing liquidity and/or credit facilities to or for
the account of such SPC to fund the Loans made by such SPC or to support the
securities (if any) issued by such SPC to fund such Loans; provided, however,
that except in the case of an assignment to a Granting Bank or a financial
institution that is either an affiliate of such SPC or another Lender, the
Borrower and the Servicing Agent must consent to such assignment in writing
(which consent may not be unreasonably withheld).

          SECTION 10.08.  Right of Setoff.  (a)  Upon the occurrence and during
the continuation of any Event of Default each Lender is hereby authorized, in
addition to any other right or remedy that any Lender may have by operation of
law or otherwise, at any time and from time to time, without notice to the
Borrower except to the extent required by applicable law (any such notice being
expressly waived by the Borrower to the maximum extent possible under applicable
law), and subject to any requirements or limitations imposed by applicable law,
to exercise its banker's lien or right of setoff and apply any and 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 or any of its Affiliates to
or for the credit or the account of the Borrower against any and all the
obligations of the Borrower now or hereafter existing under this Agreement,
irrespective of whether or not such Lender shall have made any demand under this
Agreement and although such obligations may be unmatured.

          (b)  Each Lender agrees promptly to notify the Administrative Agents
and the Borrower after any such setoff and application; provided, however, that,
to the extent permitted by applicable law, the failure to give any such notice
shall not affect the validity of such setoff and application.

          (c)  Upon the insolvency or bankruptcy of any Lender, the Borrower is
hereby authorized, in addition to any other right or remedy that it may have by
operation of law or otherwise, at any time and from time to time, to exercise a
right of setoff and apply any and all amounts due and owing it from such Lender
to or for the account of the Borrower against amounts due from the Borrower to
such Lender.  Any such setoffs may be made only against payments due to such
insolvent or bankrupt Lender, when and as the same become due, and no setoff may
be made against any amount due and payable to any other Lender.  The Borrower
may not exercise any right of setoff with respect to all or any portion of
deposits which are insured by the Federal Deposit Insurance Corporation.

 
                                                                              87

          SECTION 10.09.  Severability.  In case any one or more of the
provisions contained in this Agreement shall be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.  The parties shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

          SECTION 10.10.  Cover Page, Table of Contents and Section Headings.
The cover page, Table of Contents and Section headings used herein are for
convenience of reference only, are not part of this Agreement and are not to
affect the construction of or be taken into consideration in interpreting this
Agreement.

          SECTION 10.11.  Counterparts; Effectiveness.  This Agreement may be
signed in any number of counterparts with the same effect as if the signatures
thereon and hereon were upon the same instrument.  This Agreement shall become

agreements referred to in Section 2.08(c) and any promissory notes delivered
pursuant hereto constitute the entire contract between the parties relative to
the subject matter hereof.  Any previous agreement among the parties with

implied, is intended to confer upon any party other than the parties hereto and
thereto and Indemnitees referred to in Section 10.05(b) any rights, remedies,
obligations or liabilities under or by reason of this Agreement or such letter
agreements or promissory notes.

 
                                                                              88

          SECTION 10.14.  Confidentiality.  Each of the Administrative Agents,
the Servicing Agent, the Fronting Bank, the Lenders and the SPC's (as defined in
Section 10.07(h)) agrees to maintain the confidentiality of the Information (as
defined below), except that Information may be disclosed (a) to its and its
Affiliates' directors, officers, employees and agents, including accountants,
legal counsel and other advisors (it being understood that the persons to whom
such disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential), (b) to the
extent requested by any regulatory authority, (c) to the extent required by
applicable laws or regulations or by any subpoena or similar legal process, (d)
to any other party to this Agreement, (e) in connection with the exercise of any
remedies hereunder or any suit, action or proceeding relating to this Agreement
or the enforcement of rights hereunder, (f) subject to obtaining a written
agreement containing provisions substantially the same as those of this Section
from the intended recipient of such Information, to any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement (including any assignee or any
prospective assignee of an SPC of the type described in the last sentence of
Section 10.07(h)), (g) with the consent of the Borrower, (h) for purposes of
Section 10.07(h) only, to any rating agency or (i) to the extent such
Information (x) becomes publicly available other than as a result of a breach of
this Section or (y) becomes available to the Administrative Agents, the
Servicing Agent, the Fronting Bank or any Lender on a nonconfidential basis from
a source other than the Borrower.  For the purposes of this Section,
"Information" means all information received from the Borrower relating to the
Borrower or its business, other than any such information that is available to
the Administrative Agents, the Servicing Agent, the Fronting Bank or any Lender
on a nonconfidential basis prior to disclosure by the Borrower.  Any person
required to maintain the confidentiality of Information as provided in this
Section shall be considered to have complied with its obligation to do so if
such person has exercised the same degree of care to maintain the
confidentiality of such Information as such person would accord to its own
confidential information.

          SECTION 10.15.  Limitation on Recourse to General Partners; Pari Passu
Obligations.  (a) The Lenders, the Administrative Agents, the Servicing Agent
and the Fronting Bank agree that payment and performance of the obligations due
to them from the Borrower under this Agreement and any promissory notes
delivered hereunder shall be obligations of the Borrower only (and of MAI to the
extent set forth in Article IX), and none of the Lenders, the Administrative
Agents, the Servicing Agent or the Fronting Bank shall have any claim against or
recourse (whether by operation of law or otherwise) to Lyondell GP or Millennium
GP, any of their Affiliates (other than the Borrower and its 

 
                                                                              89

Subsidiaries) or any director, officer, employee, agent or advisor of any such
person in respect of such obligations.

          (b)  The Asset Contribution Agreement between Lyondell, Lyondell LP
and the Borrower (as referred to in the definition of "Asset Contribution
Agreements") contains provisions under which the Borrower would be obligated to
reimburse Lyondell for any amounts paid by Lyondell on account of the principal
of or interest on the Assumed Lyondell Debt.  The Lenders acknowledge and agree
that the obligations of the Borrower in respect of such reimbursement
obligations will rank pari passu with the Obligations.

 
          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed by their duly authorized officers as of the day and year first
above written.

To:  Bank of American National Trust
     and Savings Association, as Servicing
     Agent and Documentation Agent, and
     The Chase Manhattan Bank, as
     Syndication Agent, and each Lender
     named on the signature pages to the
     Credit Agreement referred to below

                             EQUISTAR CHEMICALS, LP

Ladies and Gentlemen:

          This opinion is furnished to you pursuant to Section 4.02(b) of the
Credit Agreement dated as of November 25,  1997 among Equistar Chemicals, LP, as
Borrower; Millennium America Inc., as Guarantor; the Lenders from time to time
party thereto; Bank of America National Trust and Savings Association ("BofA"),
as Servicing Agent and Documentation Agent; The Chase Manhattan Bank ("Chase"),
as Syndication Agent; and each of BofA and Chase, as Administrative Agents (the
"Credit Agreement").  Capitalized terms used herein and not otherwise defined
herein have the meanings given to them in the Credit Agreement.

          I am the General Counsel of Millennium America Inc. (the "Guarantor");
and I, or individuals under my direction, have examined originals, or copies
certified or otherwise identified, of the Credit Agreement, the Asset
Contribution Agreement to which the Borrower, Millennium Petrochemicals Inc. and
Millennium LP are a party (the "Millennium Asset Contribution Agreement"),
certificates of public officials and  other documents, as the basis for my
opinion hereinafter set forth.

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

          1.   The Guarantor is a corporation duly organized, validly existing
and in good standing under the laws of the State of Delaware.  The Guarantor has
the requisite corporate power and authority to execute and deliver the Credit
Agreement and to perform its obligations under Article IX of the Credit
Agreement, and all such actions have been duly and validly authorized by all
necessary corporate proceedings on its part.

 
          2.   The execution and delivery of the Credit Agreement and the
performance of  the Guarantor's obligations under Article IX thereof do not (a)
require any consent or approval of, registration or filing with, or any other
action by, any Governmental Authority, except such as have been obtained, made
or taken or the failure to obtain, make or take which would not reasonably be
expected to result in a Material Adverse Effect, (b) violate any provision of
its certificate of incorporation or bylaws, (c) violate any applicable federal
law or regulation or any law or regulation of the State of New York or the
General Corporation Law of the State of Delaware or any order of any
Governmental Authority binding on it, (d) result in a material breach of or
constitute (alone or with notice or lapse of time or both) a material default
under any indenture, material agreement or other instrument to which it is a
party, or by which it or any of its properties or assets is bound or (e) result
in the creation or imposition of any Lien on any of its material properties or
assets.

          3.   The Credit Agreement has been duly executed and delivered by the
Guarantor and constitutes a legal, valid and binding obligation of the
Guarantor, enforceable against the Guarantor in accordance with its terms,
subject to (a) applicable bankruptcy, insolvency, reorganization, fraudulent
conveyance or transfer, moratorium and other laws affecting creditors' rights
and remedies generally, (b) general principles of equity (regardless of whether
considered in a proceeding in equity or at law) and (c) any implied covenants of
good faith and fair dealing.

          4.   Neither the Guarantor nor any of its Subsidiaries, is a "holding
company" or a "subsidiary company" of a "holding company", within the meaning of
the Public Utility Holding Company Act of 1935.

          5.   The Asset Contribution Agreement and the conveyancing documents
contemplated thereby are effective to transfer the assets covered thereby,
subject to obtaining from third parties all requisite consents to the transfer
of those assets (the "Third Party Consents").  No Third Party Consent is
required for the transfer of any assets covered by the Asset Contribution
Agreement, except such that have been obtained or the failure to obtain which
would not reasonably be expected to result in a Material Adverse Affect.

          The foregoing opinion is subject to the following assumptions,
qualifications and limitations:

          A.  I have, without independent verification, relied on certificates
     of representatives of the Guarantor and the representations and warranties
     of the Guarantor contained in the Credit Agreement with respect to the
     accuracy of the factual matters contained therein and assumed (i) that each
     party to the Credit Agreement has the power and authority to enter into the
     Credit Agreement and to perform its obligations thereunder (other than the
     Guarantor), (ii) the due authorization, execution and delivery of the
     Credit Agreement by each party thereto (other than the Guarantor), (iii)
     that the Credit Agreement constitutes the legal, valid, binding and
     enforceable obligation of each party thereto (other than the Guarantor) and
     (iv) the genuineness of all signatures (other than the signature of the
     Guarantor), 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.  No opinion is expressed above as to the enforceability of Section
     10.09 of the Credit Agreement or any provisions in the Credit Agreement
     that purport to (i) provide that rights and remedies are not exclusive,
     that every right and remedy is cumulative and may be exercised in addition
     to any other right or remedy and that the election of a particular remedy
     does not preclude recourse to one or more others, (ii) (a) prohibit oral
     amendments to or waivers of provisions of the Credit Agreement or (b) waive
     rights of any party that cannot be waived as a matter of applicable law,
     (iii) 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 illegal, wrongful or grossly negligent act or
     omission of that party or (iv) establish any evidentiary standard.
 

 
          C.   No opinion is expressed above as to various state and federal
laws and regulations   regulating banks or other financial institutions or the
business or lending transactions of any Agent,   Lender, SPC or the Fronting
Bank which may relate to the Credit Agreement or the transactions
contemplated thereby.

          With respect to the opinion set forth in paragraph 4 above, I have
relied upon In the Matter of Suburban Propane Gas Corporation (SEC Release No.
            -------------------------------------------------                 
22847) and In the Matter of National Distillers and Chemical Corporation (SEC
           -------------------------------------------------------------     
Release No. 22848) and the Application of Suburban Propane, L.P. for Declaration
of Non-Utility Company Status Pursuant to Section 2(a)(4) and for Exempt Holding
Company Status pursuant to Section 3(a)(3) under the Public Utility Company
Holding Act of 1935, filed with the Securities and Exchange Commission on
February 26, 1996.

          This opinion is limited to applicable federal law, the applicable law
of the State of New York and the General Corporation Law of the State of
Delaware and is rendered solely to you in connection with the above matter.
This opinion may not be relied on by you for any other purpose or relied on by
any other Person without my prior written consent, except that copies of this
opinion may be furnished to, and relied on by, any Person who is an assignee
pursuant to Section 10.07 of the Credit Agreement, other than any assignee that
is an SPC or an assignee of an SPC.
 

Very truly yours,

To:  Bank of American National Trust
     and Savings Association, as Servicing
     Agent and Documentation Agent, and
     The Chase Manhattan Bank, as
     Syndication Agent, and each Lender
     named on the signature pages to the
     Credit Agreement referred to below

                            EQUISTAR CHEMICALS, LP

Ladies and Gentlemen:

          This opinion is furnished to you pursuant to Section 4.02(b) of the
Credit Agreement dated as of November 25, 1997 among Equistar Chemicals, LP, as
Borrower; Millennium America Inc., as Guarantor; the Lenders from time to time
party thereto; Bank of America National Trust and Savings Association ("BofA"),
as Servicing Agent and Documentation Agent; The Chase Manhattan Bank ("Chase"),
as Syndication Agent; and each of BofA and Chase, as Administrative Agents (the
"Credit Agreement"). Capitalized terms used herein and not otherwise defined
herein have the meanings given to them in the Credit Agreement.

          I am the General Counsel of Lyondell Petrochemical G.P. Inc., a
general partner of the Borrower, and I, or individuals under my direction, have
examined originals, or copies certified or otherwise identified, of the Credit
Agreement, the Limited Partnership Agreement, the Asset Contribution Agreement
to which the Borrower, Lyondell Petrochemical Company and Lyondell LP are a
party (the "Asset Purchase Agreement"), certificates of public officials and
other documents as the basis for my opinion hereinafter set forth.

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

 
                                       -2-                       December 1 1997

          1.   The Borrower (a) is a limited partnership duly formed under the
Revised Uniform Limited Partnership Act of the State of Delaware (the "Delaware
Limited Partnership Act") and validly existing and in good standing under the
laws of that State, (b) has all requisite power and authority under the Limited
Partnership Agreement and the Delaware Limited Partnership Act to own its
property and assets and to carry on its business as now conducted and (c) except
where the failure to do so, individually or in the aggregate, would not
reasonably be expected to result in a Material Adverse Effect, is qualified,
licensed or registered to do business in, and is in good standing in, every
jurisdiction where such qualification, licensing or registration is required.

          2.   The Borrower has the requisite power and authority under the
Limited Partnership Agreement and the Delaware Limited Partnership Act to
execute, deliver and carry out the provisions of the Credit Agreement and to
borrow thereunder; and all such actions have been duly and validly authorized by
all necessary proceedings on its part under the Limited Partnership Agreement
and the Delaware Limited Partnership Act.

          3.   The execution, delivery and performance by the Borrower of the
Credit Agreement, the Borrowings by it thereunder and the other transactions of
the Borrower contemplated thereby and the transactions contemplated by the
Master Transaction Agreement do not (a) require any consent or approval of,
registration or filing with, or any other action by any Governmental Authority,
except such as have been obtained, made or taken and are in full force and
effect or the failure to obtain, make or take which would not reasonably be
expected to result in a Material Adverse Effect, (b) violate the Limited
Partnership Agreement, (c) violate any applicable federal law or regulation or
the Delaware Limited Partnership Act or any order of any Governmental Authority
binding on it, (d) result in a material breach of or constitute a material
default under any indenture, material agreement or other instrument to which it
is a party, or by which it or any of its properties or assets is bound or (e)
result in the creation or imposition of any Lien on any of its material
properties or assets.

          4.   There are no actions, suits or proceedings by or before any
Governmental Authority pending against or, to my knowledge, threatened against
or affecting the Borrower or any of its Subsidiaries or the respective
businesses, assets or rights of the Borrower or any of its Subsidiaries 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.

          5.   Neither the Borrower nor any of its Subsidiaries is (a) an
"investment company" within the meaning of the Investment Company Act of 1940 or
(b) a "holding company" as defined in the Public Utility Holding Company Act of
1935.

 
                                      -3-                      December 1, 1997

          6.   The Asset Contribution Agreement and the conveyancing documents
contemplated thereby are effective to transfer the assets covered thereby,
subject to obtaining from third parties all requisite consents to the transfer
of those assets (the "Third Party Consents"). No Third Party Consent is required
for the transfer of any assets covered by the Asset Contribution Agreement,
except such that have been obtained or the failure to obtain which would not
reasonably be expected to result in a Material Adverse Effect.

          7.   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 Credit
Agreement, subject to Section 35.51(f)(4) of the Texas Business and Commerce
Code.

          The foregoing opinion is subject to the following assumptions,
qualifications and limitations:

          A.   I have, without independent verification, relied on certificates
     of representatives of the Borrower and the representations and warranties
     of the Borrower contained in the Credit Agreement with respect to the
     accuracy of the factual matters contained therein and assumed (i) that each
     party to the Credit Agreement (other than the Borrower) has the power and
     authority to enter into the Credit Agreement and to perform its obligations
     thereunder, (ii) the due authorization, execution and delivery of the
     Credit Agreement by each party thereto (other than the Borrower), (iii)
     that the Credit Agreement constitutes the legal, valid, binding and
     enforceable obligation of each party thereto (other than the Borrower) and
     (iv) the genuineness of all signatures (other than the Borrower's), the
     conformity to authentic, original documents of all documents submitted to
     me as certified or photostatic copies and the authenticity of all documents
     submitted to me as originals.

          B.   No opinion is expressed above as to the enforceability of the
     Credit Agreement.
               
          C.   No opinion is expressed above as to various state and federal
     laws and regulations regulating banks or other financial institutions or
     the business or lending transactions of any Agent, Lender, SPC or the
     Fronting Bank which may relate to the Credit Agreement or the transactions
     contemplated thereby.

          This opinion is limited to applicable federal law, the applicable law
of the State of Texas and the Delaware Limited Partnership Act and is rendered
solely to you in connection with

 
                                      -4-                     December 1, 1997

To:  Bank of American National Trust
     and Savings Association, as Servicing
     Agent and Documentation Agent, and
     The Chase Manhattan Bank, as
     Syndication Agent, and each Lender
     named on the signature pages to the
     Credit Agreement referred to below

                             EQUISTAR CHEMICALS, LP

Ladies and Gentlemen:

          This opinion is furnished to you pursuant to Section 4.02(b) of the
Credit Agreement dated as of November 25,  1997 among Equistar Chemicals, LP, as
Borrower; Millennium America Inc., as Guarantor; the Lenders from time to time
party thereto; Bank of America National Trust and Savings Association ("BofA"),
as Servicing Agent and Documentation Agent; The Chase Manhattan Bank ("Chase"),
as Syndication Agent; and each of BofA and Chase, as Administrative Agents (the
"Credit Agreement").  Capitalized terms used herein and not otherwise defined
herein have the meanings given to them in the Credit Agreement.

          We have acted as counsel to the Borrower in connection with the Credit
Agreement. In that connection we have examined the Credit Agreement and
originals, or copies certified or otherwise identified, of the Limited
Partnership Agreement furnished to us by the Borrower, certificates of public
officials and representatives of the Borrower and other documents as the basis
for our opinion hereinafter set forth.

          Upon 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 a legal, valid and binding
obligation of the Borrower, enforceable against the Borrower in accordance with
its terms, subject to (a) applicable bankruptcy, insolvency, reorganization,
fraudulent conveyance or transfer, moratorium and other laws affecting
creditors' rights and remedies generally, (b) general principles of equity
(regardless 

 
                                      -2-                    December 1, 1997

of whether considered in a proceeding in equity or at law) and (c) any implied
covenants of good faith and fair dealing.

          2.   The credit transactions contemplated by the Credit Agreement do
not (a) require any consent or approval of, registration or filing with, or any
other action by, any Governmental Authority, except such as have been obtained,
made or taken and are in full force and effect or the failure to obtain, make or
take which would not reasonably be expected to result in a Material Adverse
Effect, (b) violate the terms of the Limited Partnership Agreement or (c)
violate any applicable federal law or regulation or any applicable law or
regulation of the State of New York or the Delaware Limited Partnership Act.

          3.   The Borrower is not (a) an "investment company" within the
meaning of the Investment Company Act of 1940 or (b) a "holding company" as
defined in the Public Utility Holding Company Act of 1935.

          4.   The execution, delivery and performance of the Credit Agreement
by the Borrower, the Borrowing by the Borrower thereunder and the use of the
proceeds thereof in accordance with Section 3.10 and the other provisions of the
Credit Agreement do not violate Regulation U or X of the Board of  Governors of
the Federal Reserve System.

          The foregoing opinion is subject to the following assumptions,
qualifications and limitations:

          A.  We have, without independent verification, relied on certificates
     of representatives of the Borrower and the representations and warranties
     of the Borrower contained in the Credit Agreement with respect to the
     accuracy of the factual matters contained therein and assumed (i) that each
     party to the Credit Agreement has the power and authority to enter into the
     Credit Agreement and to perform its obligations thereunder, (ii) the due
     authorization, execution and delivery of the Credit Agreement by each party
     thereto, (iii) that the Credit Agreement constitutes the legal, valid,
     binding and enforceable obligation of each party thereto (other than the
     Borrower) 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.  No opinion is expressed above as to the enforceability of Section
     10.09 of the Credit Agreement or any provisions in the Credit Agreement
     that purport to (i) provide that rights and remedies are not exclusive,
     that every right and remedy is cumulative and may be exercised in addition
     to any other right or remedy and that the election of a particular remedy

 
                                      -3-                     December 1, 1997

     does not preclude recourse to one or more others, (ii) (a) prohibit oral
     amendments to or waivers of provisions of the Credit Agreement or (b) waive
     rights of any party that cannot be waived as a matter of applicable law,
     (iii) 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 illegal, wrongful or grossly negligent act or
     omission of that party or (iv) establish any evidentiary standard.
 
          C.   No opinion is expressed above as to various state and federal
     laws and   regulations regulating banks or other financial institutions or
     the business or lending transactions of any Agent, Lender, SPC or the
     Fronting Bank which may relate to the Credit Agreement or the transactions
     contemplated thereby.

          This opinion is limited to applicable federal law, the applicable law
of the State of New York and the Delaware Revised Uniform Limited Partnership
Act and is rendered solely to you in connection with the above matter.  This
opinion may not be relied on by you for any other purpose or relied on by any
other Person without our prior written consent, except that copies of this
opinion may be furnished to, and relied on by, any Person who is an assignee
pursuant to Section 10.07 of the Credit Agreement, other than any assignee that
is an SPC or an assignee of an SPC.

                                    Very truly yours,
