         By this Amendment No. 4 to the Tender Offer Statement on Schedule 14D-1
(the "Schedule 14D-1"), Phelps Dodge Corporation, a New York corporation
("Phelps Dodge"), and its wholly owned subsidiary, CAV Corporation, a Delaware
corporation ("Purchaser"), hereby amend and supplement their Schedule 14D-1
filed with the Securities and Exchange Commission (the "Commission") on
September 3, 1999, as amended on September 22, 1999, September 27, 1999 and
October 1, 1999, with respect to the Purchaser's exchange offer to acquire all
outstanding shares of common stock, no par value per share, and the associated
preferred share purchase rights (each, a "Cyprus Amax Share" and collectively,
the "Cyprus Amax Shares"), of Cyprus Amax Minerals Company, a Delaware
corporation ("Cyprus Amax"), at a share price of, subject to proration, either
$20.54, net to the seller in cash, or 0.3500 shares of Phelps Dodge per Cyprus
Amax Share, upon the terms and subject to the conditions set forth in the Phelps
Dodge prospectus, dated September 2, 1999, as amended (the "Prospectus") and in
the related Letter of Election and Transmittal, which together constitute the
Offer. Pursuant to Instruction F of Schedule 14D-1, this statement is submitted
in satisfaction of the reporting obligation of the Purchaser under Section 13(d)
of the Securities Exchange Act of 1934, as amended.


Item 4 is hereby amended and supplemented as follows:

Item 4.  Source and Amount of Funds or Other Consideration.

         Phelps Dodge estimates that the total amount of funds required pursuant
to the Cyprus Amax exchange offer to pay the cash consideration in connection
with the exchange of all Cyprus Amax shares outstanding will be approximately
$691 million. Phelps Dodge expects to obtain these funds from cash on hand, from
its existing revolving credit facility, and from the additional credit facility
described below.

         Phelps Dodge has entered into a Credit Agreement, dated as of October
18, 1999, with Citibank, N.A., as Administrative Agent and as a lender, First
Union National Bank and Morgan Guaranty Trust Company of New York, as
Syndication Agents and as lenders, Salomon Smith Barney Inc., as Arranger and
Book Manager, and other lenders that may become parties thereto. Under this
Credit Agreement, the lenders will provide Phelps Dodge with a $650 million
revolving credit facility that Phelps Dodge may use to pay cash consideration in
connection with the Cyprus Amax exchange offer and for general corporate
purposes.

         The lenders' obligations to make loans under this credit facility are
subject to customary conditions, including (i) completion of the Cyprus Amax
exchange offer; (ii) absence of any material adverse change to Phelps Dodge
since December 31, 1998; and (iii) accuracy and completeness of representations
and warranties made by Phelps Dodge and information furnished by Phelps Dodge.

         Loans under the credit facility will be unsecured, and will bear
interest, at Phelps Dodge's option, at either (a) Citibank's base rate, or (b)
LIBOR plus a variable margin of between 0.40% and 2.00% (plus an additional
premium of 0.25% if amounts are drawn after


<PAGE>



December 20, 1999), depending on Phelps Dodge's credit rating and the amount
Phelps Dodge has outstanding under the facility from time to time. The facility
will terminate on the earlier of January 31, 2000 or the date on which the
Phelps Dodge/Cyprus Amax merger is completed.


Item 5 is hereby amended and supplemented as follows:

Item 5.  Purpose of the Tender Offer and Plans or Proposals of Bidder.

         In accordance with the Agreement and Plan of Merger, dated as of

"Merger Agreement"), upon purchase by Purchaser of Cyprus Amax Shares, Phelps
Dodge is entitled to designate a certain number of directors on the Cyprus Amax
Board of Directors. As of October 16, 1999, eight members of the Board of
Directors resigned and were replaced by two designees of Phelps Dodge, Douglas
C. Yearley and J. Steven Whisler. Two of the current Cyprus Amax Board members,
Willam C. Bousquette and Milton H. Ward, will remain on the Cyprus Amax Board
until completion of the merger between Purchaser and Cyprus Amax. As of October
23, 1999, Manuel J. Iraola will be Phelps Dodge's third designee to the Cyprus
Amax Board.


Item 6 is hereby amended and supplemented as follows:

Item 6.  Interest in Securities of the Subject Company.

         (a) - (b) The Offer expired at 12:00 midnight, New York City time, on

all of such Cyprus Amax Shares. A copy of the press release issued on October

         PHELPS DODGE ANNOUNCES EXPIRATION OF CYPRUS AMAX EXCHANGE OFFER
 ------------------------------------------------------------------------------

      PHOENIX, AZ, October 18, 1999 - Phelps Dodge Corporation (NYSE: PD)
announced today that its offer to exchange $7.61 in cash and 0.2203 Phelps Dodge
shares for each share of Cyprus Amax Minerals Company (NYSE: CYM) on a fully
prorated basis expired at 12:00 midnight, New York City time, October 15, 1999.

      Phelps Dodge said that it has been informed by ChaseMellon Shareholder
Services, the exchange agent for the offer, that based on a preliminary count,
approximately 81,750,496 shares of Cyprus Amax stock have been tendered,
representing approximately 89.87% of the outstanding shares of Cyprus Amax. Of
the approximately 81,750,496 shares tendered, approximately 51,822,175 elected
cash, 29,576,966 elected stock and 351,355 made no election. The total shares
tendered include 17,280,264 shares tendered pursuant to notices of guaranteed
delivery. All shares of Cyprus Amax tendered were accepted for exchange by
Phelps Dodge according to the terms of the exchange offer.

      Based on preliminary tabulations, since the cash election was
oversubscribed, all Cyprus Amax shareholders requesting stock will receive
0.3500 Phelps Dodge shares per Cyprus Amax share. Those shareholders requesting
cash will be prorated to receive approximately $13.36 in cash and approximately
0.1223 shares of Phelps Dodge common stock per Cyprus Amax share. Phelps Dodge
is in the process of determining the exact proration, which it expects to
announce later this week and commence payment.

      Douglas C. Yearley, Chairman and Chief Executive Officer of Phelps Dodge,
said, "We are another step closer to completing the Cyprus Amax acquisition and
beginning to realize its compelling benefits for shareholders of both
companies."

      Phelps Dodge Corporation is among the world's largest producers of copper.
The company also is one of the world's largest producers of carbon black, one of
the world's largest manufacturers of magnet wire, and has operations and
investments in mines and wire and cable manufacturing facilities around the

    such Lender as part of such Revolving Credit Borrowing when such Advance, as
    a result of such failure, is not made on such date.

    the date of any Revolving Credit Borrowing that such Lender will not make
    available to the Agent such Lender's ratable portion of such Revolving
    Credit Borrowing, the Agent may assume that such Lender has made such
    portion available to the Agent on the date of such Revolving Credit
    Borrowing in accordance with clause (a) of this Section 2.2 and the Agent
    may, in reliance upon such assumption, make available to the Borrower on
    such date a corresponding amount. If and to the extent that such Lender
    shall not have so made such ratable portion available to the Agent, such
    Lender and the Borrower severally agree to repay to the Agent forthwith on
    demand such corresponding amount together with interest thereon, for each

    Revolving Credit Borrowing and (ii) in the case of such Lender, the Federal
    Funds Rate. If such Lender shall repay to the Agent such corresponding
    amount, such amount so repaid shall constitute such Lender's Advance as part
    of such Revolving Credit Borrowing for purposes of this Agreement.

         (e) The failure of any Lender to make the Advance to be made by it as
    part of any Revolving Credit Borrowing shall not relieve any other Lender of
    its obligation, if any, hereunder to make its Advance on the date of such
    Revolving Credit Borrowing, but no Lender shall be responsible for the
    failure of any other Lender to make the Advance to be made by such other
    Lender on the date of any Revolving Credit Borrowing.

    such Base Rate Advance shall be Converted or paid in full.

              (ii) Eurodollar Rate Advances. During such periods as such Advance
    is a Eurodollar Rate Advance, a rate per annum equal at all times during
    each Interest Period for such Advance to the sum of (x) the Eurodollar Rate
    for such Interest Period for such Advance plus (y) the Applicable Margin in
    effect from time to time, payable in arrears on the last day of such
    Interest Period and on the date such Eurodollar Rate Advance shall be
    Converted or paid in full.

         (b) Default Interest. Upon the occurrence and during the continuance of
    an Event of Default under Section 6.1(a), the Borrower shall pay interest on
    (i) the unpaid principal amount of each Advance owing to each Lender,
    payable in arrears on the dates referred to in clause (a)(i) or (a)(ii)
    above, at a rate per annum equal at all times to 2% per annum above the rate
    per annum required to be paid on such Advance pursuant to clause (a)(i) or
    (a)(ii) above and (ii) to the fullest extent permitted by law, the amount of
    any interest, fee or other amount payable hereunder that is not paid when
    due, from the date such amount shall be due until


                                       16
<PAGE>


    such amount shall be paid in full, payable in arrears on the date such
    amount shall be paid in full and on demand, at a rate per annum equal at all
    times to 2% per annum above the rate per annum required to be paid on Base
    Rate Advances pursuant to clause (a)(i) above.

         Section 2.7. Interest Rate Determination.

         (a) Each Reference Bank agrees to furnish to the Agent timely
    information for the purpose of determining each Eurodollar Rate. If any one
    or more of the Reference Banks shall not furnish such timely information to
    the Agent for the purpose of determining any such interest rate, the Agent
    shall determine such interest rate on the basis of timely information
    furnished by the remaining Reference Banks. The Agent shall give prompt
    notice to the Borrower and the Lenders of the applicable interest rate
    determined by the Agent for purposes of Section 2.6(a)(i) or (ii), and the
    rate, if any, furnished by each Reference Bank for the purpose of
    determining the interest rate under Section 2.6(a)(ii).

         (b) If, with respect to any Eurodollar Rate Advances, the Required
    Lenders notify the Agent that the Eurodollar Rate for any Interest Period
    for such Advances will not adequately reflect the cost to such Required
    Lenders of making, funding or maintaining their respective Eurodollar Rate
    Advances for such Interest Period, the Agent shall forthwith so notify the
    Borrower and the Lenders, whereupon (i) each Eurodollar Rate Advance will
    automatically, on the last day of the then existing Interest Period
    therefor, Convert into a Base Rate Advance, and (ii) the obligation of the
    Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall
    be suspended until the Agent shall notify the Borrower and the Lenders that
    the circumstances causing such suspension no longer exist.

         (c) If the Borrower shall fail to select the duration of any Interest
    Period for any Eurodollar Rate Advances in accordance with the provisions
    contained in the definition of "Interest Period" in Section 1.1, the Agent
    will forthwith so notify the Borrower and the Lenders and such Advances will
    automatically, on the last day of the then existing Interest Period
    therefor, be Converted into Base Rate Advances.

         (d) On the date on which the aggregate unpaid principal amount of
    Eurodollar Rate Advances comprising any Borrowing shall be reduced, by
    payment or prepayment or otherwise, to less than $5,000,000, such Advances
    shall automatically Convert into Base Rate Advances.

         (e) Upon the occurrence and during the continuance of any Event of
    Default, (i) each Eurodollar Rate Advance will automatically, on the last
    day of the then existing Interest Period therefor, Convert into a Base Rate
    Advance and (ii) the obligation of the Lenders to make, or to Convert
    Advances into, Eurodollar Rate Advances shall be suspended.


                                       17

         (f) If Dow Jones Markets Telerate Page 3750 is unavailable and fewer
    than two Reference Banks furnish timely information to the Agent for
    determining the Eurodollar Rate for any Eurodollar Rate Advances,

              (i) the Agent shall forthwith notify the Borrower and the Lenders
    that the interest rate cannot be determined for such Eurodollar Rate
    Advances,

              (ii) with respect to Eurodollar Rate Advances, each such Advance
    will automatically, on the last day of the then existing Interest Period
    therefor, be prepaid by the Borrower or be automatically Converted into a
    Base Rate Advance (or if such Advance is then a Base Rate Advance, will
    continue as a Base Rate Advance), and

              (iii) the obligation of the Lenders to make Eurodollar Rate
    Advances or to Convert Advances into Eurodollar Rate Advances shall be
    suspended until the Agent shall notify the Borrower and the Lenders that the
    circumstances causing such suspension no longer exist.

         Section 2.8. Optional Conversion of Advances. The Borrower may on any
Business Day, upon notice given to the Agent not later than 11:00 A.M. (New York
City time) on the third Business Day prior to the date of the proposed
Conversion and subject to the provisions of Sections 2.7 and 2.11, Convert all
Advances of one Type comprising the same Borrowing into Advances of the other
Type; provided, however, that any Conversion of Eurodollar Rate Advances into
Base Rate Advances shall be made only on the last day of an Interest Period for
such Eurodollar Rate Advances, any Conversion of Base Rate Advances into
Eurodollar Rate Advances shall be in an amount not less than the minimum amount
specified in Section 2.2(b) and no Conversion of any Advances shall result in
more separate Revolving Credit Borrowings than permitted under Section 2.2(b).
Each such notice of a Conversion shall, within the restrictions specified above,
specify (i) the date of such Conversion, (ii) the Advances to be Converted, and
(iii) if such Conversion is into Eurodollar Rate Advances, the duration of the
initial Interest Period for each such Advance. Each notice of Conversion shall
be irrevocable and binding on the Borrower.

         Section 2.9. Prepayments of Advances. The Borrower may, upon notice at
least two Business Days' prior to the date of such prepayment, in the case of
Eurodollar Rate Advances, and not later than 2:00 P.M. (New York City time) on
the date of such prepayment, in the case of Base Rate Advances, to the Agent
stating the proposed date and aggregate principal amount of the prepayment, and
if such notice is given the Borrower shall, prepay the outstanding principal
amount of the Advances comprising part of the same Revolving Credit Borrowing in
whole or ratably in part, together with accrued interest to the date of such
prepayment on the principal amount prepaid; provided, however, that (x) each
partial prepayment shall be in an aggregate principal amount of $10,000,000 or
an integral multiple of $5,000,000 in excess thereof and (y) in the event of any
such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to
reimburse the Lenders in respect thereof pursuant to Section 8.4(c).


                                       18

         Section 2.10. Increased Costs.

         (a) If after the date hereof, due to either (i) the introduction of or
    any change in any Requirement of Law or in the interpretation or application
    thereof or (ii) the compliance with any guideline or request from any
    central bank or other Governmental Authority (whether or not having the
    force of law), there shall result an increase in the cost to any Lender by
    an amount which such Lender deems to be material of agreeing to make or
    making, funding or maintaining Eurodollar Rate Advances (excluding for
    purposes of this Section 2.10 any such increased costs resulting from (i)
    Taxes or Other Taxes (as to which Section 2.13 shall govern) and (ii)
    changes in the basis of taxation of overall net income or overall gross
    income by the United States or by the foreign jurisdiction or state under
    the laws of which such Lender is organized or has its Applicable Lending
    Office or any political subdivision thereof), then the Borrower shall
    promptly pay to the Lender additional amounts sufficient to compensate such
    Lender for such increased cost. If any Lender becomes entitled to claim any
    additional amounts pursuant to this Section, it shall promptly notify the
    Borrower in writing, through the Agent, of the event by reason of which it
    has become so entitled; provided, that the Borrower shall not be required to
    compensate a Lender for costs in respect of any period beginning before the
    date which is 120 days prior to the date on which the Borrower receives
    notice that such costs have been imposed, or if such costs have been imposed
    retroactively, the period beginning on such earlier date on which such costs
    shall have become effective (excluding however, any portion of such period
    which is after the date of adoption of or change in the relevant Requirement
    of Law and more than 120 days prior to the date on which the Borrower had
    received notice that such costs had been imposed). A certificate as to the
    amount of such increased cost, submitted to the Borrower and the Agent by
    such Lender, shall be conclusive, absent manifest error.

         (b) If any Lender shall have determined that the adoption of or any
    change in any Requirement of Law regarding capital adequacy or in the
    interpretation or application thereof or compliance by such Lender or any
    corporation controlling such Lender with any request or directive regarding
    capital adequacy (whether or not having the force of law) from any
    Governmental Authority made subsequent to the date hereof does or shall have
    the effect of reducing the rate of return on such Lender's or such
    corporation's capital as a consequence of its obligations hereunder to a
    level below that which such Lender or such corporation could have achieved
    but for such change or compliance (taking into consideration such Lender's
    or such corporation's policies with respect to capital adequacy) by an
    amount deemed by such Lender to be material, then from time to time, after
    submission by such Lender to the Borrower (with a copy to the Administrative
    Agent) of a written request therefor, the borrower shall pay to such Lender
    such additional amount or amounts as will compensate such Lender or
    corporation for such reduction.

         Section 2.11. Illegality. Notwithstanding any other provision of this
Agreement, the adoption of, or any change in, any Requirement of Law or in the


                                       19
<PAGE>


interpretation or application thereof shall make it unlawful for any Lender to
make or maintain Eurodollar Rate Advances as contemplated by this Agreement, (a)
the commitment of such Lender hereunder to make or maintain Eurodollar Rate
Advances, continue Eurodollar Rate Advances as such and convert Base Rate
Advances to Eurodollar Rate Advances shall forthwith be canceled and (b) such
Lender's Revolving Credit Borrowings then outstanding as Eurodollar Rate
Advances, if any, shall be converted automatically to Base Rate Advances on the
respective last days of the then current Interest Periods with respect to such
Revolving Credit Borrowings or within such earlier period as required by law. If
any such conversion of a Eurodollar Rate Advance occurs on a day which is nor
the last day of the then current Interest Period with respect thereto, the
Borrower shall pay to such Lender such amounts, if any, as may be required
pursuant to Section 8.4(c).

         Section 2.12. Payments and Computations.

         (a) The Borrower shall make each payment hereunder not later than 2:00
    P.M. (New York City time) on the day when due to the Agent at the Agent's
    Account in same day funds. The Agent will promptly thereafter cause to be
    distributed like funds relating to the payment of principal or interest or
    facility fees ratably (other than amounts payable pursuant to Section 2.10,
    2.13 or 8.4(c)) to the Lenders for the account of their respective
    Applicable Lending Offices, and like funds relating to the payment of any
    other amount payable to any Lender to such Lender for the account of its
    Applicable Lending Office, in each case to be applied in accordance with the
    terms of this Agreement. Upon its acceptance of an Assignment and Acceptance
    and recording of the information contained therein in the Register pursuant
    to Section 8.7(d), from and after the effective date specified in such
    Assignment and Acceptance, the Agent shall make all payments hereunder and
    under the Revolving Credit Notes in respect of the interest assigned thereby
    to the Lender assignee thereunder, and the parties to such Assignment and
    Acceptance shall make all appropriate adjustments in such payments for
    periods prior to such effective date directly between themselves.

         (b) The Borrower hereby authorizes each Lender, if and to the extent
    payment owed to such Lender is not made when due hereunder or under the
    Revolving Credit Note held by such Lender, to charge from time to time
    against any or all of the Borrower's accounts with such Lender any amount so
    due.

         (c) All computations of interest based on the Base Rate shall be made
    by the Agent on the basis of a year of 365 or 366 days, as the case maybe,
    all computations of interest based on the Eurodollar Rate, or the Federal
    Funds Rate and of fees shall be made by the Agent on the basis of a year of
    360 days, in each case for the actual number of days (including the first
    day but excluding the last day) occurring in the period for which such
    interest or facility fees are payable. Each determination by the Agent of an
    interest rate hereunder shall be conclusive and binding for all purposes,
    absent manifest error.


                                       20
<PAGE>


         (d) Whenever any payment hereunder or under the Revolving Credit Notes
    shall be stated to be due on a day other than a Business Day, such payment
    shall be made on the next succeeding Business Day, and such extension of
    time shall in such case be included in the computation of payment of
    interest or facility fee, as the case may be; provided, however, that, if
    such extension would cause payment of interest on or principal of Eurodollar
    Rate Advances to be made in the next following calendar month, such payment
    shall be made on the next preceding Business Day.

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

         Section 2.13. Taxes.

         (a) Any and all payments by the Borrower hereunder or under the
    Revolving Credit Notes shall be made, in accordance with Section 2.12, free
    and clear of and without deduction for any and all present or future taxes,
    levies, imposts, deductions, charges or withholdings, and all liabilities
    with respect thereto ("Taxes"), excluding, (i) Taxes imposed on the Agent or
    any Lender as a result of a present or former connection between the Agent
    or such Lender and the jurisdiction of the Governmental Authority imposing
    such Tax or any political subdivision or taxation authority thereof or
    therein (other than any such connection arising solely from the Agent or
    such Lender having executed, delivered or performed its obligations or
    received a payment under, or enforced, this Agreement or the Revolving
    Credit Notes) and (ii) Taxes imposed by the United States on any Lender
    other than as a result of a Change in Law (as defined below) relating to
    such Lender (all such non-excluded Taxes in respect of payments hereunder or
    under the Revolving Credit Notes being hereinafter referred to as
    "Non-Excluded Taxes"). If the Borrower shall be required by law to deduct
    any Taxes from or in respect of any sum payable hereunder or under any
    Revolving Credit Note to any Lender or the Agent, (i) the Borrower shall
    make such deductions, (ii) the Borrower shall pay the full amount deducted
    to the relevant taxation authority or other authority in accordance with
    applicable law and (iii) if such Taxes are Non-Excluded Taxes, the sum
    payable shall be increased as may be necessary so that after making all
    required deductions of Non-Excluded Taxes (including deductions of
    Non-Excluded Taxes applicable to additional sums payable under this Section
    2.13), such Lender or the Agent (as


                                       21
<PAGE>


    the case may be) receives an amount equal to the sum it would have received
    had no such deductions been made.

         (b) In addition, the Borrower shall pay any present or future stamp or
    documentary taxes or any other excise or property taxes, charges or similar
    levies that arise from any payment made hereunder or under the Revolving
    Credit Notes or from the execution, delivery or registration of, performing
    under, or otherwise with respect to, this Agreement or the Revolving Credit
    Notes (hereinafter referred to as "Other Taxes").

         (c) If the Borrower fails to pay any Non-Excluded Taxes when due to the
    relevant taxation authority or fails to remit to the Agent the required
    documentary evidence set forth in clause (d) below, the Borrower shall
    indemnify each Lender and the Agent for any Non-Excluded Taxes (including
    any Non-Excluded Taxes imposed by any jurisdiction on amounts payable under
    this Section 2.13(c)) with respect to amounts payable by such Lender or the
    Agent (as the case may be) as a result of such failure and any liability
    (including penalties, interest and expenses) arising therefrom or with
    respect thereto. This indemnification shall be made within 30 days from the
    date such Lender or the Agent (as the case may be) makes written demand
    therefor.

         (d) Reasonably promptly after the date of any payment of Taxes pursuant
    to clause (a), the Borrower shall furnish to the Agent, at its address
    referred to in Section 8.2, the original or a certified copy of a receipt
    evidencing such payment. In the case of any payment hereunder or under the
    Revolving Credit Notes by or on behalf of the Borrower through an account or
    branch outside the United States or by or on behalf of the Borrower by a
    payor that is not a United States person, if the Borrower determines that no
    Taxes are payable in respect thereof, the Borrower shall furnish, or shall
    cause such payor to furnish, to the Agent, at such address, an opinion of
    counsel reasonably acceptable to the Agent stating that such payment is
    exempt from deduction of Taxes. For purposes of this clause (d) and clause
    (e), the terms "United States" and "United States person" shall have the
    meanings specified in Section 7701 of the Internal Revenue Code.

         (e) Each Lender organized under the laws of a jurisdiction other than
    the United States of America or a State thereof, shall (i) on or prior to
    the date such Lender becomes a Lender hereunder, provide each of the Agent
    and the Borrower with (A) two duly completed and accurate copies of Internal
    Revenue Service forms 1001 or 4224, as appropriate, or any successor or
    other form prescribed by the Internal Revenue Service, certifying that such
    Lender is exempt from United States withholding tax on payments pursuant to
    this Agreement or the Revolving Credit Notes and (B) an Internal Revenue
    Service form W-8 or W-9, or any successor form, as the case may be,
    certifying that such Lender is entitled to an exemption from United Stated
    backup withholding tax; (ii) provide each of the Agent and the Borrower with
    two further duly completed and accurate copies of any such form or
    certification on or before the date that any such form


                                       22
<PAGE>


    or certification expires or becomes obsolete and after the occurrence of an
    event requiring a change in the most recent form previously provided by it
    to the Borrower (unless in any such case a Change in Law (as defined below)
    in the circumstances described in Section 2.13(e)(ii) above has occurred
    prior to the date on which any such delivery would otherwise be required
    which would prevent such Lender from duly completing and delivering any such
    form with respect to it and such Lender so advises the Borrower in writing);
    and (iii) obtain such extensions of time for filing as may reasonably be
    requested by the Agent or the Borrower. In addition, each Lender shall, upon
    the written request of the Borrower, provide the Borrower with such other
    forms, certificates or documentation as may be reasonably necessary to claim
    any exemption from, or reduced rate of, Taxes for which the Borrower in
    liable under Section 2.13(a); provided that such action shall not cause the
    imposition on such Lender of any material additional costs or legal,
    regulatory or administrative burdens. If an event occurs after the date on
    which any form, certificate or documentation is submitted by a Lender that
    renders such item or the information set forth therein incorrect, such
    Lender shall promptly notify the Agent and Borrower in writing of such
    incorrectness.

         (f) For any period with respect to which a Lender has failed to provide
    the Borrower with the appropriate form described in Section 2.13(e) (other
    than if such failure is due to a Change in Law (as defined below) or if such
    form otherwise is not required under Section 2.13(e) above), such Lender
    shall not be entitled to indemnification under Section 2.13(a) or (c) with
    respect to Taxes deducted by the Borrower by reason of such failure;
    provided, however, that the Borrower shall take such steps as such Lender
    shall reasonably request to assist the Lender to recover such Taxes.

         (g) Any Lender claiming any additional amounts payable pursuant to this
    Section 2.13 agrees to use reasonable efforts (consistent with its internal
    policy and legal and regulatory restrictions) to change the jurisdiction of
    its Eurodollar Lending Office if the making of such a change would avoid the
    need for, or reduce the amount of, any such additional amounts that may
    thereafter accrue and would not, in the reasonable judgment of such Lender,
    be otherwise disadvantageous to such Lender.

         (h) For purposes of this Section 2.13, "Change in Law" shall mean, with
    respect to any Lender, a change in the Internal Revenue Code, the Treasury
    Regulations thereunder or any official interpretation thereof (or any
    officially proposed changes in the interpretation thereof) or an amendment
    or revocation of an applicable United States income tax treaty after the
    date such Lender became a Lender hereunder.

         Section 2.14. Sharing of Payments, Etc. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the Advances owing to it (other than
pursuant to Section 2.10, 2.13 or 8.4(c)) in excess of its ratable share of
payments on account of the Advances


                                       23

<PAGE>


obtained by all the Lenders, such Lender shall forthwith purchase from the other
Lenders such participations in the Advances owing to them as shall be necessary
to cause such purchasing Lender to share the excess payment ratably with each of
them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each Lender
shall be rescinded and such Lender shall repay to the purchasing Lender the
purchase price to the extent of such recovery together with an amount equal to
such Lender's ratable share (according to the proportion of (i) the amount of
such Lender's required repayment to (ii) the total amount so recovered from the
purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered. The Borrower
agrees that any Lender so purchasing a participation from another Lender
pursuant to this Section 2.14 may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off) with respect
to such participation as fully as if such Lender were the direct creditor of the
Borrower in the amount of such participation.

         Section 2.15. Evidence of Debt.

         (a) Each Lender shall maintain in accordance with its usual practice an
    account or accounts evidencing the indebtedness of the Borrower to such
    Lender resulting from each Advance owing to such Lender from time to time,
    including the amounts of principal and interest payable and paid to such
    Lender from time to time hereunder in respect of Advances. The Borrower
    agrees that upon notice by any Lender to the Borrower (with a copy of such
    notice to the Agent) to the effect that a Revolving Credit Note is required
    or appropriate in order for such Lender to evidence (whether for purposes of
    pledge, enforcement or otherwise) the Advances owing to, or to be made by,
    such Lender, the Borrower shall promptly execute and deliver to such Lender
    a Revolving Credit Note payable to the order of such Lender in a principal
    amount up to the Commitment of such Lender.

         (b) The Register maintained by the Agent pursuant to Section 8.7(d)
    shall include a control account, and a subsidiary account for each Lender,
    in which accounts (taken together) shall be recorded (i) the date and amount
    of each Borrowing made hereunder, the Type of Advances comprising such
    Borrowing and, if appropriate, the Interest Period applicable thereto, (ii)
    the terms of each Assignment and Acceptance delivered to and accepted by it,
    (iii) the amount of any principal or interest due and payable or to become
    due and payable from the Borrower to each Lender hereunder and (iv) the
    amount of any sum received by the Agent from the Borrower hereunder and each
    Lender's share thereof.

         (c) Entries made in good faith by the Agent in the Register pursuant to
    clause (b) above, and by each Lender in its account or accounts pursuant to
    clause (a) above, shall be prima facie evidence of the amount of principal
    and interest due and payable or to become due and payable from the Borrower
    to, in the case of the Register, each Lender and, in the case of such
    account or accounts, such Lender, under this Agreement, absent manifest
    error; provided, however, that the failure of the Agent or such Lender to
    make an entry, or any finding that an entry


                                       24
<PAGE>


    is incorrect, in the Register or such account or accounts shall not limit or
    otherwise affect the obligations of the Borrower under this Agreement.

         Section 2.16. Use of Proceeds. The proceeds of the Advances shall be
available (and the Borrower agrees that it shall use such proceeds) solely for
(i) general corporate purposes of the Borrower and its Subsidiaries, including
commercial paper backstop and (ii) financing the Exchange Offer, the Merger and
transaction costs related thereto. Notwithstanding anything herein to the
contrary, no proceeds of the Advances shall be used to finance any portion of
the Borrower's acquisition of ASARCO Incorporated.

                                  ARTICLE III

                     CONDITIONS TO EFFECTIVENESS AND LENDING

         Section 3.1. Conditions Precedent to Effectiveness of Section 2.1.
Section 2.1 of this Agreement shall become effective on and as of the first date
(the "Effective Date") on which the following conditions precedent have been
satisfied:

         (a) There shall have occurred no Material Adverse Change since December
    31, 1998.

         (b) There shall exist no action, suit, investigation, litigation or
    proceeding affecting the Borrower or any of its Subsidiaries pending or
    threatened before any court, governmental agency or arbitrator that could
    reasonably be expected to result in a Material Adverse Change.

         (c) Nothing shall have come to the attention of the Lenders during the
    course of their due diligence investigation to lead them to believe that the
    written information supplied to them by the Borrower (i) as to any factual
    matters (excluding any such information referred to in paragraph (ii)
    below), was or has become misleading, incorrect or incomplete in any
    material respect or (ii) as to any financial and business projections,
    budgets, pro forma data and forecasts (all of the foregoing together being
    "Projections") was not prepared in good faith or the grounds on which such
    Projections were prepared are no longer reasonable (it being understood by
    the parties hereto that such Projections are subject to significant
    uncertainties and contingencies many of which are beyond the control of the
    Borrower and that no assurance can be given (without limiting any provision
    of this Agreement or the Loan Documents) that any such Projections will be
    realized). Without limiting the generality of the foregoing, the Lenders
    shall have been given such access to the management, records, books of
    account, contracts and properties of the Borrower and its Subsidiaries as
    they shall have requested.

         (d) All governmental and material third party consents and approvals
    (including any Hart-Scott-Rodino Antitrust Improvements Act of 1976
    antitrust clearance) necessary in connection with the Exchange Offer and any
    other

    been obtained (without the imposition of any conditions that are not
    acceptable to the Lenders) and shall remain in effect and all applicable
    periods shall have expired without any action by any Governmental Authority
    which may inhibit or adversely affect the Exchange Offer, and no law or
    regulation shall be applicable in the reasonable judgment of the Lenders
    that restrains, prevents or imposes materially adverse conditions upon the
    transactions contemplated hereby or by the Related Documents.

         (e) The Borrower shall have notified each Lender and the Agent in
    writing as to the proposed Effective Date.

         (f) The Borrower shall have paid all accrued fees and expenses of the
    Agent and the Lenders (including the reasonable fees and expenses of a
    single firm of counsel to the Agent) to the extent invoiced to the Borrower
    at least one Business Day before the Effective Date.

         (g) On the Effective Date, the following statements shall be true and
    the Agent shall have received for the account of each Lender a certificate

    Date, stating that:

    are true and correct on and as of the Effective Date, and

              (ii) No event has occurred and is continuing that constitutes a
    Default.

    extent requested by any Lender pursuant to Section 2.15.

              (ii) Certified copies of the Certificate of Incorporation, the
    Charter and by-laws of the Borrower and certified copies of the resolutions
    of the Board of Directors of the Borrower authorizing the execution,
    delivery and performance of, and borrowing under, this Agreement and the
    Revolving Credit Notes, and certified copies of all documents evidencing
    other necessary corporate action and governmental approvals, if any, with
    respect to this Agreement and the Revolving Credit Notes.

              (iii) A certificate of the Secretary or an Assistant Secretary of
    the Borrower certifying the names and true signatures of the officers of the
    Borrower authorized to sign this Agreement and the Revolving Credit Notes
    and the other documents to be delivered hereunder.

    and amendment thereto certified by the Secretary or an Assistant Secretary
    of the Borrower to be true and correct copies of such documents, together
    with all amendments, supplements and other modifications thereto.

    for the Agent, in form and substance satisfactory to the Agent.

         (i) The terms and conditions of the Exchange Offer and the Related
    Documents shall be as stated in the Offer to Purchase and shall not be, or
    have been, amended without the approval of the Required Lenders (such
    approval not to be unreasonably withheld). All conditions precedent to the
    consummation of the Exchange Offer (including the minimum tender condition)
    shall have been satisfied and not waived without the consent of the Required
    Lenders.

         Section 3.2. Conditions Precedent to Each Revolving Credit Borrowing
and Extension Date. The obligation of each Lender to make an Advance on the
occasion of each Revolving Credit Borrowing shall be subject to the conditions
precedent that the Effective Date shall have occurred and on the date of such
Revolving Credit Borrowing the following statements shall be true (and each of
the giving of the applicable Notice of Revolving Credit Borrowing and the
acceptance by the Borrower of the proceeds of such Revolving Credit Borrowing
shall constitute a representation and warranty by the Borrower that on the date
of such Borrowing such statements are true):

              (i) the representations and warranties contained in Section 4.1
    (except the representation set forth in Section 4.1(b)) are correct on and
    as of such date, before and after giving effect to such Revolving Credit
    Borrowing, and to the application of the proceeds therefrom, as though made
    on and as of such date; and

              (ii) no event has occurred and is continuing, or would result from
    such Revolving Credit Borrowing or from the application of the proceeds
    therefrom, that constitutes a Default;

and the Agent shall have received such other approvals, opinions or documents as
any Lender through the Agent may reasonably request.

         Section 3.3. Determinations Under Section 3.1. For purposes of
determining compliance with the conditions specified in Section 3.1, each Lender
shall be deemed to have consented to, approved or accepted or to be satisfied
with each document or other matter required thereunder to be consented to or
approved by or acceptable or satisfactory to the Lenders unless an officer of
the Agent responsible for the transactions


                                       27

<PAGE>


contemplated by this Agreement shall have received notice from such Lender prior
to the date that the Borrower, by notice to the Lenders, designates as the
proposed Effective Date, specifying its objection thereto. The Agent shall
promptly notify the Lenders of the occurrence of the Effective Date.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

         Section 4.1. Representations and Warranties of the Borrower. The
Borrower represents and warrants as follows:

         (a) Financial Condition. The consolidated balance sheet of the Borrower
    and its consolidated Subsidiaries as at December 31, 1998 and the related
    consolidated statements of income and of cash flows for the fiscal year
    ended on such date, reported on by PricewaterhouseCoopers LLP, copies of
    which have heretofore been furnished to each Lender, are complete and
    correct and present fairly the consolidated financial condition of the
    Borrower and its consolidated Subsidiaries as at such dates, and the
    consolidated results of their operations and their consolidated cash flows
    for the fiscal years then ended. The unaudited consolidated balance sheet of
    the Borrower and its consolidated Subsidiaries as at June 30, 1999 and the
    related unaudited consolidated statements of income and of cash flows for
    the six-month period ended on such date, certified by a Responsible Officer,
    copies of which have heretofore been furnished to each Lender, are complete
    and correct and present fairly the consolidated financial condition of the
    Borrower and its consolidated Subsidiaries as at such date, and the
    consolidated results of their operations and their consolidated cash flows
    for the three-month period then ended (subject to normal year-end audit
    adjustments). All such financial statements, including the related schedules
    and notes thereto, have been prepared in accordance with GAAP applied
    consistently throughout the periods involved (except as approved by such
    accountants or Responsible Officer, as the case may be, and as disclosed
    therein).

         (b) No Change. No event or circumstance since December 31, 1998 has
    occurred or is existing which has resulted in, or after giving effect to the
    reasonably projected outcome or effect thereof will result in, a Material
    Adverse Change.

         (c) Corporate Existence. The Borrower (i) is a corporation duly
    organized, validly existing and in good standing under the laws of the State
    of New York, (ii) has the corporate power and authority, and the legal
    right, to own and operate its property, to lease the property it operates as
    lessee and to conduct the business in which it is currently engaged and
    (iii) is duly qualified as a foreign corporation and in good standing under
    the laws of each jurisdiction where its ownership, lease or operation of
    property or the conduct of its business requires such qualification except
    to the extent that the failure to be so qualified would not be reasonably
    expected to result in a Material Adverse Change.


                                       28
<PAGE>


         (d) Corporate Power; Authorization; Enforceable Obligations. The
    Borrower has the corporate power and authority, and the legal right, to
    make, deliver and perform this Agreement, the Loan Documents and the Related
    Documents and to borrow hereunder and has taken all necessary corporate
    action to authorize the borrowings on the terms and conditions of this
    Agreement, the Loan Documents and the Related Documents and to authorize the
    execution, delivery and performance of this Agreement, the Loan Documents
    and the Related Documents. No consent or authorization of, filing with,
    notice to or other act by or in respect of, any Governmental Authority or
    any other Person is required in connection with the borrowings hereunder or
    the transactions contemplated hereby or by the Related Documents or with the
    execution, delivery, performance, validity or enforceability of the Loan
    Documents or the Related Documents except such as have been obtained or made
    and are in full force and effect. This Agreement and each Related Document
    has been, and each Loan Document will be, duly executed and delivered on
    behalf of the Borrower. This Agreement constitutes, and each other Loan
    Document and the Related Documents to be executed by it when executed and
    delivered will constitute, a legal, valid and binding obligation of the
    Borrower enforceable against the Borrower in accordance with its terms,
    except as enforceability may be limited by applicable bankruptcy,
    insolvency, reorganization, moratorium or similar laws affecting the
    enforcement of creditors' rights generally and by general equitable
    principles (whether enforcement is sought by proceedings in equity or at
    law).

         (e) No Legal Bar. The execution, delivery and performance of the Loan
    Documents and the Related Documents, the borrowings hereunder and the use of
    the proceeds thereof will not violate the certificate of incorporation,
    charter or by-laws of the Borrower or any Requirement of Law or Contractual
    Obligation of the Borrower or of any of its Principal Domestic Subsidiaries
    and will not result in, or require, the creation or imposition of any Lien
    on any of its or their respective properties or revenues pursuant to any
    provision of its certificate of incorporation, charter or by-laws or any
    such Requirement of Law or Contractual Obligation.

         (f) No Material Litigation. No litigation, investigation or proceeding
    (including any Environmental Action) of or before any arbitrator or
    Governmental Authority is pending or, to the knowledge of the Borrower,
    overtly threatened by or against the Borrower or any of its Principal
    Domestic Subsidiaries or against any of its or their respective properties
    or revenues (a) (except as disclosed in the Offer to Purchase) with respect
    to any of the Loan Documents, the Related Documents, the Exchange Offer or
    any of the transactions contemplated hereby or thereby, or (b) which after
    giving effect to the reasonably projected outcome or effect thereof, will
    result in a Material Adverse Change.

         (g) No Default. Neither the Borrower nor any of its Principal Domestic
    Subsidiaries is in default under or with respect to any of its Contractual
    Obligations in any respect which has resulted in or, after giving effect to


                                       29
<PAGE>


    the reasonably projected outcome or effect thereof, will result in, a
    Material Adverse Change. No Default has occurred and is continuing.

         (h) Ownership of Property; Liens. Each of the Borrower and its
    Principal Domestic Subsidiaries has good record and marketable title in fee
    simple to, or a valid leasehold interest in, all its real property, and good
    title to, or a valid leasehold interest in, all its other property, and none
    of such property is subject to any Lien (except Liens which are permitted by
    Section 5.3(a)) except to the extent that the absence of such title or
    leasehold interest has not resulted in, and after giving effect to the
    reasonably projected outcome or effect thereof, will not result in, a
    Material Adverse Change.

         (i) Compliance with Law. The Borrower and each of its Principal
    Domestic Subsidiaries is in compliance with all Requirements of Law and
    Contractual Obligations except to the extent that the failure to comply
    therewith has not resulted in, and, after giving effect to the reasonably
    projected outcome or effect thereof, will not result in, a Material Adverse
    Change.

         (j) Taxes. Each of the Borrower and its Principal Domestic Subsidiaries
    has filed or caused to be filed all tax returns which, to the knowledge of
    the Borrower, are required to be filed and has paid all taxes shown to be
    due and payable on said returns or on any assessments made against it or any
    of its property and all other taxes, fees or other charges imposed on it or
    any of its property by any Governmental Authority (other than any the amount
    or validity of which are currently being contested in good faith by
    appropriate proceedings and with respect to which reserves in conformity
    with GAAP have been provided on the books of the Borrower or its Principal
    Domestic Subsidiaries, as the case may be) and, to the knowledge of the
    Borrower, no tax Lien (other than a Lien for taxes that are not yet due and
    payable) has been filed, with respect to any such tax, fee or other charge
    which, in any case, has resulted in, or after giving effect to the
    reasonably projected outcome or effect thereof will result in, a Material
    Adverse Change.

         (k) Federal Regulations. The Borrower is not engaged in the business of
    extending credit for the purpose of "purchasing" or "carrying" any "margin
    stock" within the respective meanings of each of the quoted terms under
    Regulation U of the Board of Governors of the Federal Reserve System as now
    and from time to time hereafter in effect and no proceeds of an Advance have
    been or will be used for any purpose which violates the provisions of the
    Regulations of such Board of Governors. At no time would the Obligations be
    directly or "indirectly secured" by assets of the Borrower and its
    consolidated Subsidiaries that are "margin stock" (pursuant to, and as such
    captioned terms are defined in, Section 221.2(g) of Regulation U), provided
    that in any event not more than 25% of the value of the assets of the
    Borrower and its consolidated Subsidiaries subject to such arrangements
    shall be represented by such margin stock. If requested by any Lender or the
    Agent, the Borrower will furnish to the


                                       30
<PAGE>


    Agent and each Lender a statement to the foregoing effect in conformity with
    the requirements of FR Form U-1 referred to in said Regulation U.

         (l) ERISA. Neither a Reportable Event nor an "accumulated funding
    deficiency" (within the meaning of Section 412 of the Code or Section 302 of
    ERISA) nor any other event has occurred during the five-year period prior to
    the date on which this representation is made or deemed made with respect to
    any Plan which has resulted in or, after giving effect to the reasonably
    projected outcome or effect thereof, will result in, a Material Adverse
    Change.

         (m) Investment Company Act; Other Regulations. The Borrower is not an
    "investment company", or a company "controlled" by an "investment company",
    within the meaning of the Investment Company Act of 1940, as amended. The
    Borrower is not subject to regulation under any Federal or state statute or
    regulation which limits its ability to incur indebtedness of the type being
    incurred by it pursuant to this Agreement.

         (n) Subsidiaries. Set forth in Schedule III is a complete and accurate
    list showing all Subsidiaries (other than inactive Subsidiaries) existing as
    of the date of this Agreement, designating certain Subsidiaries as Principal
    Domestic Subsidiaries and showing the jurisdiction of incorporation of each
    Principal Domestic Subsidiary and the percentage of the outstanding shares
    of Capital Stock of such Subsidiaries owned (directly or indirectly) by the
    Borrower or any Subsidiary. All of the outstanding Capital Stock of each
    Principal Domestic Subsidiary has been validly issued, is fully paid and
    non-assessable and is owned by the Borrower or one or more of the Principal
    Domestic Subsidiaries free and clear of all Liens. Each Principal Domestic
    Subsidiary is duly incorporated, validly existing and in good standing under
    the laws of the jurisdiction of its incorporation.

         (o) Environmental Matters. Except as disclosed in the Borrower's Annual
    Report on Form 10-K for fiscal year 1998, to the best knowledge of the
    Borrower, the Borrower and each Principal Domestic Subsidiary has complied
    with all applicable Environmental Laws, except for failures to comply which
    have not resulted in, and after giving effect to the reasonably projected
    outcome or effect thereof will not result in, a Material Adverse Change.
    Except as disclosed in the Borrower's Annual Report on Form 10-K for fiscal
    year 1998 or on Schedule IV, to the best knowledge of the Borrower, there
    are no events, conditions or circumstances involving the Borrower, any of
    its Principal Domestic Subsidiaries or any Subsidiaries of such Principal
    Domestic Subsidiaries with respect to management of any Hazardous Materials,
    environmental pollution or contamination or employee health or safety which
    have resulted in, or after giving effect to the reasonably projected outcome
    or effect thereof will result in, a Material Adverse Change.

         (p) Information. All written information provided by the Borrower to
    the Agent, the Arranger and Book Manager or any Lender in connection with
    this


                                       31
<PAGE>


    Agreement, the Loan Documents or the Related Documents and the transactions
    contemplated hereby and thereby, at the date hereof or (if provided after
    the date hereof) at the date it was provided (i) in the case of any factual
    matter (excluding any such information referred to in paragraph (ii)), is
    true and accurate in all material respects and (ii) in the case of financial
    and business projections, budgets, pro forma data and forecasts (all of the
    foregoing being, together, "Projections"), contained therein, were prepared
    in good faith and on reasonable grounds (it being understood by the parties
    hereto that such Projections are subject to significant uncertainties and
    contingencies, many of which are beyond the control of the Borrower and that
    no assurance can be given (without limiting any other provision of this
    Agreement or the Loan Documents) that any such Projections will be
    realized).

         (q) Year 2000. The Borrower has (i) initiated a review and assessment
    of all areas within its and each of its Subsidiaries' business and
    operations (including those affected by suppliers, vendors and customers)
    that could be adversely affected by computer applications used by the
    Borrower or any of its Subsidiaries (or suppliers, vendors and customers)
    being unable to recognize and perform properly date sensitive functions
    involving certain dates prior to and any date after December 31, 1999 (the
    "Year 2000 Problem"), (ii) developed a plan and timetable for addressing the
    Year 2000 Problem on a timely basis and (iii) to date, implemented that plan
    substantially in accordance with such timetable. Based on the foregoing, the
    Borrower believes that all computer applications of the Borrower and its
    Subsidiaries that are material to its or any of its Subsidiaries' business
    and operations are reasonably expected on a timely basis to be able to
    perform properly date-sensitive functions for all dates before, on and after
    January 1, 2000 and the Borrower has no reason to believe that all computer
    applications of its suppliers, vendors and customers that are material to
    its or any of its Subsidiaries' business and operations are not reasonably
    expected on a timely basis to be able to perform properly date-sensitive
    functions for all dates before, on and after January 1, 2000, except in the
    aggregate, to the extent that a failure to do so could not reasonably be
    expected to result in a Material Adverse Change.

         (r) The Merger. The Merger Agreement has been approved by the boards of
    directors of both Cyprus and the Borrower, is in full force and effect and
    none of the terms of the Exchange Offer or the Merger Agreement have been
    amended or waived without the consent of the Required Lenders. Neither
    Cyprus nor the Borrower is in default of any of its obligations under the
    Merger Agreement. The number of shares of Cyprus accepted for payment or
    exchange in the Exchange Offer is equal to no less than the minimum number
    of shares, determined on a fully diluted basis, necessary to approve the
    consummation of the Merger in accordance with the provisions of any
    applicable Requirement of Law or provision in the Borrower's certificate of
    incorporation, charter, by-laws, or any instrument or agreement which is
    binding on the Borrower.

<PAGE>


    such period has observed or performed all of its covenants and other
    agreements, and satisfied every condition, contained in this Agreement and
    in the Revolving Credit Notes to be observed, performed or satisfied by it

    Subsidiaries to pay, discharge or otherwise satisfy, in all material
    respects, (i) all material taxes, assessments and governmental charges or
    levies imposed on its property when due by it and (ii) at or before maturity
    or otherwise in accordance with reasonable business practices, all its
    material obligations of whatever nature; provided, that the Borrower or its
    Principal Domestic Subsidiaries, as the case may be, may contest taxes,
    assessments, charges, levies or obligations in good faith by appropriate
    proceedings if it maintains reserves in conformity with GAAP with respect
    thereto.

    discontinuing any business if, in the opinion of its board of directors,
    such discontinuance is in the best interests of the Borrower and not
    disadvantageous in any material respect to any Lender or the holder of any
    Revolving Credit Note or (ii) the abandonment, modification or termination
    of rights, privileges and franchises of the Borrower, if, in the opinion of
    the Board of Directors, such abandonment, modification or termination is in

    such discontinuance is in the best interest of the Borrower and not
    disadvantageous in any material respect to any Lender or the holder of any
    Revolving Credit Note; maintain, and cause each Principal Domestic
    Subsidiary to maintain, with financially sound and reputable insurance
    companies insurance on all its property of a character usually insured by

    business; and furnish to each Lender, upon written request, full information

    Subsidiary may self-insure (which term shall include insurance by an
    affiliated insurance company) against any of the risks required to be
    insured against pursuant to this clause (f) so long as such self-insurance
    is not excessive in the light of self-insurance by companies similarly
    situated and operating like properties, provided, in the case of any
    insurance required by law, that such risk is permitted to be self-insured
    under applicable law and such self-insurance complies with applicable law.

    reasonable notice to the Borrower, to discuss the business, operations,
    properties and financial and other condition of the Borrower and its

    the events in clause (A) or (B), individually or in the aggregate, could
    reasonably be expected to involve an amount of $15,000,000 or more.

    Each notice pursuant to this clause (h) shall be accompanied by a statement

    together with all secured Indebtedness for Money Borrowed of the Borrower
    and its Principal Domestic Subsidiaries and all other Attributable Debt in
    respect of Sale and Lease-Back Transactions existing at such time (other

                                   THE AGENT

         Section 7.1. Authorization and Action. Each Lender hereby appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers and discretion under this Agreement as are delegated to the Agent by
the terms hereof, together with such powers and discretion as are reasonably
incidental thereto. As to any matters not expressly provided for by this
Agreement (including enforcement or collection of the Revolving Credit Notes),
the Agent shall not be required to exercise any discretion or take any action,
but shall be required to act or to refrain from acting (and shall be fully
protected in so acting or refraining from acting) upon the instructions of the
Required Lenders, and such instructions shall be binding upon all Lenders and
all holders of Revolving Credit Notes; provided, however, that the Agent shall
not be required to take any action that exposes the Agent to personal liability
or that is contrary to this Agreement or applicable law. The Agent agrees to
give to each Lender prompt notice of each notice given to it by the Borrower
pursuant to the terms of this Agreement.

         Section 7.2. Agent's Reliance, Etc. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or
omitted to be taken by it or them under or in connection with this Agreement,
except for its or their own gross negligence or willful misconduct. Without
limitation of the generality of the foregoing, the Agent: (i) may treat the
Lender that made any Advance as the holder of the Indebtedness resulting
therefrom until the Agent receives and accepts an Assignment and Acceptance
entered into by such Lender, as assignor, and an Eligible Assignee, as assignee,
as provided in Section 8.7; (ii) may consult with legal counsel (including
counsel for the Borrower), independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (iii) makes no warranty or representation to any Lender
and shall not be responsible to any Lender for any statements, warranties or
representations (whether written or oral) made in or in connection with this
Agreement; (iv) shall not have any duty to ascertain or to inquire as to the
performance or observance of any of the terms, covenants or conditions of this
Agreement on the part of the Borrower or to inspect the property (including the
books and records) of the Borrower; (v) shall not be responsible to any Lender
for the due execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other instrument or document
furnished pursuant hereto; and (vi) shall incur no liability under or in respect
of this Agreement by acting upon any notice, consent, certificate or other
instrument or writing (which may be by telecopier, telegram or telex) believed
by it to be genuine and signed or sent by the proper party or parties.

         Section 7.3. Citibank and Affiliates. With respect to its Commitment,
the Advances made by it and the Revolving Credit Note issued to it, Citibank
shall have the same rights and powers under this Agreement as any other Lender
and may exercise the same as though it were not the Agent; and the term "Lender"
or "Lenders" shall, unless otherwise expressly indicated, include Citibank in
its individual capacity. Citibank and its Affiliates may accept deposits from,
lend money to, act as trustee under


                                       42

<PAGE>


indentures of, accept investment banking engagements from and generally engage
in any kind of business with, the Borrower, any of its Subsidiaries and any
Person who may do business with or own securities of the Borrower or any such
Subsidiary, all as if Citibank were not the Agent and without any duty to
account therefor to the Lenders.

         Section 7.4. Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon the Agent or any other Lender and
based on the financial statements referred to in Section 4.1 and such other
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent or
any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

         Section 7.5. Indemnification. The Lenders agree to indemnify the Agent
(to the extent not reimbursed by the Borrower), ratably according to the
respective principal amounts of the Advances then owed to each of them (or if no
Advances are at the time outstanding, ratably according to the respective
amounts of their Commitments), from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever that may be imposed
on, incurred by, or asserted against the Agent in any way relating to or arising
out of this Agreement or any action taken or omitted by the Agent under this
Agreement (collectively, the "Indemnified Costs"), provided that no Lender shall
be liable for any portion of the Indemnified Costs resulting from the Agent's
gross negligence or willful misconduct. Without limitation of the foregoing,
each Lender agrees to reimburse the Agent promptly upon demand for its ratable
share of any out-of-pocket expenses (including reasonable counsel fees) incurred
by the Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement, to the extent that the Agent
is not reimbursed for such expenses by the Borrower. In the case of any
investigation, litigation or proceeding giving rise to any Indemnified Costs,
this Section 7.5 applies whether any such investigation, litigation or
proceeding is brought by the Agent, any Lender or a third party.

         Section 7.6. Successor Agent. The Agent may resign at any time by
giving written notice thereof to the Lenders and the Borrower and may be removed
at any time with or without cause by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a
successor Agent, provided that the Borrower shall have the right to consent to
such successor Agent (which consent shall not be unreasonably withheld or
delayed). If no successor Agent shall have been so appointed by the Required
Lenders, and shall have accepted such appointment, within 30 days after the
retiring Agent's giving of notice of resignation or the Required Lenders removal
of the retiring Agent, then the retiring Agent may, on behalf of the Lenders,
appoint a successor Agent, which shall be a commercial bank organized under the
laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $500,000,000. Upon the acceptance of
any appointment as


                                       43
<PAGE>


Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, discretion, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations under this Agreement. After any retiring Agent's
resignation or removal hereunder as Agent, the provisions of this Article VII
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Agent under this Agreement.

         Section 7.7. Other Agents. Each party hereby acknowledges that (a) any
co-agent and any other Lender (except in its capacity as a Lender) designated as
an "agent" on the cover page hereof and (b) Salomon Smith Barney Inc. as
arranger and book manager, shall in each case have no liability hereunder.

effective when deposited in the mails, telecopied, delivered to the telegraph

counterpart of any amendment or waiver of any provision of this Agreement or the
Revolving Credit Notes or of any Exhibit hereto to be executed and delivered

thereof.

         Section 8.3. No Waiver; Remedies. No failure on the part of any Lender
or the Agent to exercise, and no delay in exercising, any right hereunder or
under any Loan Document shall operate as a waiver thereof; nor shall any single

thereof or the exercise of any other right. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

         Section 8.4. Costs and Expenses; Indemnity.

         (a) The Borrower agrees to pay on demand all costs and expenses of the
    Agent in connection with the preparation, execution, delivery,
    administration, modification and amendment of this Agreement, the Loan
    Documents and the other documents to be delivered hereunder, including (i)
    all due diligence, syndication (including out-of-pocket printing,
    distribution and bank meetings), transportation, computer and duplication
    expenses and (ii) the reasonable fees and expenses of counsel for the Agent
    with respect thereto and with respect to advising the Agent as to its rights
    and responsibilities under this Agreement and the Loan Documents. The
    Borrower further agrees to pay on demand all costs and expenses of the Agent
    and the Lenders, if any (including reasonable counsel fees and expenses), in
    connection with the enforcement (whether through negotiations, legal
    proceedings or otherwise) of this Agreement, the Loan Documents and the
    other documents to be delivered hereunder or thereunder, including
    reasonable fees and expenses of counsel for the Agent and the Lenders in
    connection with the enforcement of rights under this Section 8.4(a).

         (b) The Borrower agrees to indemnify and hold harmless the Agent, the
    Arranger and Book Manager and each Lender and each of their Affiliates and
    their officers, directors, employees, agents and advisors (each, an
    "Indemnified Party") from and against any and all claims, damages, losses,
    liabilities and expenses (including reasonable fees and expenses of counsel)
    incurred by or asserted or awarded against any Indemnified Party, in each
    case arising out of or in connection with or by reason of (including in
    connection with any investigation, litigation or proceeding or preparation
    of a defense in connection therewith) (i) this Agreement, the Loan
    Documents, the Related Documents, any of the transactions contemplated
    herein or therein or the actual or proposed use of the proceeds of the
    Advances or (ii) the actual or alleged presence of Hazardous Materials on
    any property of the Borrower or any of its Subsidiaries or any Environmental
    Action relating in any way to the Borrower or any of its


                                       45

<PAGE>


    Subsidiaries, except to the extent such claim, damage, loss, liability or
    expense is found in a final, non-appealable judgment by a court of competent
    jurisdiction to have resulted from such Indemnified Party's gross negligence
    or willful misconduct. In the case of an investigation, litigation or other
    proceeding to which the indemnity in this Section 8.4(b) applies, such
    indemnity shall be effective whether or not such investigation, litigation
    or proceeding is brought by the Borrower, its directors, shareholders or
    creditors or an Indemnified Party or any other Person or any Indemnified
    Party is otherwise a party thereto and whether or not the transactions
    contemplated hereby are consummated. The Borrower also agrees not to assert
    any claim for special, indirect, consequential or punitive damages against
    the Agent, any Lender, any of their Affiliates, or any of their respective
    directors, officers, employees, attorneys and agents, and the Agent and each
    Lender agrees not to assert any claim for special, indirect, consequential
    or punitive damages against the Borrower, any of its Affiliates, or any of
    their respective directors, officers, employees, attorneys and agents, on
    any theory of liability arising out of or otherwise relating to the this
    Agreement, any Loan Document, any of the transactions contemplated herein or
    in the Related Documents or the actual or proposed use of the proceeds of
    the Advances.

         (c) If any payment of principal of, or Conversion of, any Eurodollar
    Rate Advance, is made by the Borrower to or for the account of a Lender
    other than on the last day of the Interest Period for such Advance, as a
    result of a payment or Conversion pursuant to Section 2.7(d) or (e), 2.9 or
    2.11, acceleration of the maturity of the Advances pursuant to Section 6.1
    or for any other reason or by an Eligible Assignee to a Lender other than on
    the last day of the Interest Period for such Advance upon an assignment of
    rights and obligations under this Agreement pursuant to Section 8.7 as a
    result of a demand by the Borrower pursuant to Section 8.7(a), the Borrower
    shall, upon demand by such Lender (with a copy of such demand to the Agent),
    pay to the Agent for the account of such Lender any amounts required to
    compensate such Lender for any additional losses, costs or expenses that it
    shall actually incur as a result of such payment or Conversion, including
    any loss (excluding loss of anticipated profits), cost or expense incurred
    by reason of the liquidation or reemployment of deposits or other funds
    acquired by any Lender to fund or maintain such Advance.

         (d) Without prejudice to the survival of any other agreement of the
    Borrower hereunder, the agreements and obligations of the Borrower contained
    in Sections 2.10 and 2.13 and this Section 8.4 shall survive the payment in
    full of principal, interest and all other amounts payable hereunder and
    under the Loan Documents.

         Section 8.5. Right of Setoff. Upon the occurrence and during the
continuance of any Event of Default, each Lender and each of its Affiliates is
hereby authorized at any time and from time to time, to the fullest extent
permitted by law, to set off 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 such Affiliate to or for the credit or the
account of the Borrower against any and all of the


                                       46
<PAGE>


obligations of the Borrower now or hereafter existing under this Agreement and
the Loan Documents, whether or not such Lender shall have made any demand under
this Agreement or such Loan Document and although such obligations may be
unmatured. Each Lender agrees promptly to notify the Agent and the Borrower
after any such set-off and application, provided that the failure to give such
notice shall not affect the validity of such set-off and application. The rights
of each Lender and its Affiliates under this Section are in addition to other
rights and remedies (including other rights of set-off) that such Lender and its
Affiliates may have.

         Section 8.6. Binding Effect. This Agreement shall become effective
(other than Section 2.1, which shall only become effective upon satisfaction of
the conditions precedent set forth in Section 3.1) when it shall have been
executed by the Borrower and the Agent and when the Agent shall have been
notified by each Lender that such Lender has executed it and thereafter shall be
binding upon and inure to the benefit of the Borrower, the Agent and each Lender
and their respective successors and assigns, except that the Borrower shall not
have the right to assign its rights hereunder or any interest herein without the
prior written consent of the Lenders.

         Section 8.7. Assignments and Participations.

         (a) Each Lender may and, if required by the Borrower (following a
    demand by such Lender pursuant to Section 2.10 or 2.13) will, with the
    consent of the Borrower and the Agent (such consents not to be unreasonably
    withheld or delayed and which consents shall not be required from the Agent
    or the Borrower in the case of assignment to (i) an Affiliate of such Lender
    (ii) another Lender or its Affiliate or (iii) any Federal Reserve Bank
    (pursuant to Section 8.7(g)) upon at least five Business Days' notice to the
    Agent, assign to one or more Persons all or a portion of its rights and
    obligations under this Agreement (including all or a portion of its
    Commitment, the Advances owing to it and the Revolving Credit Note or Notes
    held by it); provided, however, that (i) each such assignment shall be of a
    constant, and not a varying, percentage of all rights and obligations under
    this Agreement, (ii) except in the case of an assignment to a Person that,
    immediately prior to such assignment, was a Lender or an assignment of all
    of a Lender's rights and obligations under this Agreement, the amount of the
    Commitment of the assigning Lender being assigned pursuant to each such
    assignment (determined as of the date of the Assignment and Acceptance with
    respect to such assignment) shall in no event be less than $10,000,000 or an
    integral multiple of $1,000,000 in excess thereof, (iii) each such
    assignment shall be to an Eligible Assignee, (iv) each such assignment made
    as a result of a demand by the Borrower pursuant to this Section 8.7(a)
    shall be arranged by the Borrower after consultation with the Agent and
    shall be either an assignment of all of the rights and obligations of the
    assigning Lender under this Agreement or an assignment of a portion of such
    rights and obligations made concurrently with another such assignment or
    other such assignments that together cover all of the rights and obligations
    of the assigning Lender under this Agreement, (v) no Lender shall be
    obligated to make any such assignment as a result of a demand by the
    Borrower pursuant to this Section 8.7(a) if an Event of Default has occurred


                                       47
<PAGE>


    and is continuing or unless and until such Lender shall have received one or
    more payments from either the Borrower or one or more Eligible Assignees in
    an aggregate amount at least equal to the aggregate outstanding principal
    amount of the Advances owing to such Lender, together with accrued interest
    thereon to the date of payment of such principal amount and all other
    amounts payable to such Lender under this Agreement, and (vi) the parties to
    each such assignment shall execute and deliver to the Agent, for its
    acceptance and recording in the Register, an Assignment and Acceptance,
    together with any Revolving Credit Note subject to such assignment and a
    processing and recordation fee of $3,500. Upon such execution, delivery,
    acceptance and recording, from and after the effective date specified in
    each Assignment and Acceptance, (x) the assignee thereunder shall be a party
    hereto and, to the extent that rights and obligations hereunder have been
    assigned to it pursuant to such Assignment and Acceptance, have the rights
    and obligations of a Lender hereunder and (y) the Lender assignor thereunder
    shall, to the extent that rights and obligations hereunder have been
    assigned by it pursuant to such Assignment and Acceptance, relinquish its
    rights and be released from its obligations under this Agreement (and, in
    the case of an Assignment and Acceptance covering all or the remaining
    portion of an assigning Lender's rights and obligations under this
    Agreement, such Lender shall cease to be a party hereto).

         (b) By executing and delivering an Assignment and Acceptance, the
    Lender assignor thereunder and the assignee thereunder confirm to and agree
    with each other and the other parties hereto as follows: (i) other than as
    provided in such Assignment and Acceptance, such assigning Lender makes no
    representation or warranty and assumes no responsibility with respect to any
    statements, warranties or representations made in or in connection with this
    Agreement or the execution, legality, validity, enforceability, genuineness,
    sufficiency or value of this Agreement or any other instrument or document
    furnished pursuant hereto; (ii) such assigning Lender makes no
    representation or warranty and assumes no responsibility with respect to 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; (iii) such assignee
    confirms that it has received a copy of this Agreement, together with copies
    of the financial statements referred to in Section 4.1 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;
    (iv) such assignee will, independently and without reliance upon the Agent,
    such assigning Lender or any other Lender and based on such documents and
    information as it shall deem appropriate at the time, continue to make its
    own credit decisions in taking or not taking action under this Agreement;
    (v) such assignee confirms that it is an Eligible Assignee; (vi) such
    assignee appoints and authorizes the Agent to take such action as agent on
    its behalf and to exercise such powers and discretion under this Agreement
    as are delegated to the Agent by the terms hereof, together with such powers
    and discretion as are reasonably incidental thereto; and (vii) such assignee
    agrees that it will perform in accordance with their terms all of the


                                       48
<PAGE>


    obligations that by the terms of this Agreement are required to be performed
    by it as a Lender.

         (c) Upon its receipt of an Assignment and Acceptance executed by an
    assigning Lender and an assignee representing that it is an Eligible
    Assignee, together with any Revolving Credit Note or Notes subject to such
    assignment, the Agent shall, if such Assignment and Acceptance has been
    completed and is in substantially the form of Exhibit C hereto, (i) accept
    such Assignment and Acceptance, (ii) record the information contained
    therein in the Register and (iii) give prompt notice thereof to the
    Borrower.

         (d) The Agent shall maintain at its address referred to in Section 8.2
    a copy of each Assignment and Acceptance delivered to and accepted by it and
    a register for the recordation of the names and addresses of the Lenders and
    the Commitment of, and principal amount of the Advances owing to, each
    Lender from time to time (the "Register"). The entries in the Register shall
    be conclusive and binding for all purposes, absent manifest error, and the
    Borrower, the Agent and the Lenders may treat each Person whose name is
    recorded in the Register as a Lender hereunder for all purposes of this
    Agreement. The Register shall be available for inspection by the Borrower or
    any Lender at any reasonable time and from time to time upon reasonable
    prior notice.

         (e) Each Lender may sell participations to one or more banks or other
    entities (other than the Borrower or any of its Affiliates) in or to all or
    a portion of its rights and obligations under this Agreement (including all
    or a portion of its Commitment, the Advances owing to it and any Revolving
    Credit Note or Notes held by it); provided, however, that (i) such Lender's
    obligations under this Agreement (including its Commitment to the Borrower
    hereunder) shall remain unchanged, (ii) such Lender shall remain solely
    responsible to the other parties hereto for the performance of such
    obligations, (iii) such Lender shall remain the holder of any such Revolving
    Credit Note for all purposes of this Agreement, (iv) the Borrower, the Agent
    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 (v) no participant under any such participation shall have any
    right to approve any amendment or waiver of any provision of this Agreement
    or any Loan Document, or any consent to any departure by the Borrower
    therefrom, except to the extent that such amendment, waiver or consent would
    reduce the principal of, or interest on, the Revolving Credit Notes or any
    fees or other amounts payable hereunder, in each case to the extent subject
    to such participation, or postpone any date fixed for any payment of
    principal of, or interest on, the Revolving Credit Notes or any fees or
    other amounts payable hereunder, in each case to the extent subject to such
    participation.

         (f) Any Lender may, in connection with any assignment or participation
    or proposed assignment or participation pursuant to this Section 8.7,
    disclose to the assignee or participant or proposed assignee or participant,
    any information relating to the Borrower furnished to such Lender by or on
    behalf of the Borrower; provided that, prior to any such disclosure, the
    assignee or


                                       49

<PAGE>


    participant or proposed assignee or participant shall agree to preserve the
    confidentiality of any Confidential Information relating to the Borrower
    received by it from such Lender.

         (g) Notwithstanding any other provision set forth in this Agreement,
    any Lender may at any time create a security interest in all or any portion
    of its rights under this Agreement (including the Advances owing to it and
    any Revolving Credit Note or Notes held by it) in favor of any Federal
    Reserve Bank in accordance with Regulation A of the Board of Governors of
    the Federal Reserve System.

         Section 8.8. Confidentiality. Neither the Agent nor any Lender shall
disclose any Confidential Information to any other Person without the consent of
the Borrower, other than (a) to the Agent's or such Lender's Affiliates and
their officers, directors, employees, agents and advisors and, as contemplated
by Section 8.7(f), to actual or prospective assignees and participants, and then
only on a confidential basis, (b) as required by any law, rule or regulation or
judicial process and (c) as requested or required by any state, federal or
foreign authority or examiner regulating banks or banking and having
jurisdiction over such Lender.

         Section 8.9. Governing Law. This Agreement and the Revolving Credit
Notes shall be governed by, and construed in accordance with, the laws of the
State of New York.

         Section 8.10. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.
Delivery of an executed counterpart of a signature page to this Agreement by
telecopier shall be effective as delivery of a manually executed counterpart of
this Agreement.

         Section 8.11. Jurisdiction, Etc.

         (a) Each of the parties hereto hereby irrevocably and unconditionally
    submits, for itself and its property, to the nonexclusive jurisdiction of
    any New York State court or federal court of the United States of America
    sitting in New York City, and any appellate court from any thereof, in any
    action or proceeding arising out of or relating to this Agreement or the
    Loan Documents, or for recognition or enforcement of any judgment, and each
    of the parties hereto hereby irrevocably and unconditionally agrees that all
    claims in respect of any such action or proceeding may be heard and
    determined in any such New York State court or, to the extent permitted by
    law, in such federal court. Each of the parties hereto agrees that a final
    judgment in any such action or proceeding shall be conclusive and may be
    enforced in other jurisdictions by suit on the judgment or in any other
    manner provided by law. Nothing in this Agreement shall affect any right
    that any party may otherwise have to bring any action or proceeding relating
    to this Agreement or the Loan Documents in the courts of any jurisdiction.

         (b) Each of the parties hereto irrevocably and unconditionally waives,
    to the fullest extent it may legally and effectively do so, any objection
    that it may now or hereafter have to the laying of venue of any suit, action
    or proceeding arising out of or relating to this Agreement or the Revolving
    Credit Notes in any New York State or federal court. Each of the parties
    hereto hereby irrevocably waives, to the fullest extent permitted by law,
    the defense of an inconvenient forum to the maintenance of such action or
    proceeding in any such court.

         Section 8.12. Waiver of Jury Trial. Each of the Borrower, the Agent and
the Lenders hereby irrevocably waives all right to trial by jury in any action,
proceeding or counterclaim (whether based on contract, tort or otherwise)
arising out of or relating to this Agreement or the Revolving Credit Notes or
the actions of the Agent or any Lender in the negotiation, administration,
performance or enforcement thereof.

Lender: ______________________


Principal Amount:  U.S.$______                   Dated: _______________, 199_


         FOR VALUE RECEIVED, the undersigned, PHELPS DODGE CORPORATION, a New
York corporation (the "Borrower"), HEREBY PROMISES TO PAY to the order of the
Lender named above (the "Lender") for the account of its Applicable Lending
Office on the Termination Date (as defined in the Credit Agreement referred to
below) the Principal Amount set forth above or, if less, the aggregate principal
amount of the Advances made by the Lender to the Borrower pursuant to the Credit
Agreement dated as of October [18], 1999 among the Borrower, the Lender and
certain other lenders parties thereto, and Citibank, N.A. as Agent for the
Lender and such other lenders (as amended or modified from time to time, the
"Credit Agreement"; the terms defined therein being used herein as therein
defined) outstanding on such date.

         The Borrower promises to pay interest on the unpaid principal amount of
each Advance from the date of such Advance until such principal amount is paid
in full, at such interest rates, and payable at such times, as are specified in
the Credit Agreement.

         Both principal and interest are payable in lawful money of the United
States of America to Citibank, N.A., as Agent, at 399 Park Avenue, New York, New

pursuant to the Credit Agreement, and all payments made on account of principal
thereof, shall be recorded by the Lender and, prior to any transfer hereof,
endorsed on the grid attached hereto which is part of this Promissory Note.

         This Promissory Note is one of the Revolving Credit Notes referred to
in, and is entitled to the benefits of, the Credit Agreement. The Credit
Agreement, among other things, (i) provides for the making of Advances by the
Lender to the Borrower from time to time in an aggregate amount not to exceed at
any time outstanding the U.S. dollar amount first above mentioned, the
indebtedness of the Borrower resulting from each such Advance being evidenced by
this Promissory Note and (ii) contains provisions for acceleration of the
maturity hereof upon the happening of certain stated events upon the terms and
conditions therein specified.

                            ASSIGNMENT AND ACCEPTANCE


         Reference is made to the Credit Agreement dated as of October [18],
1999 (as amended or modified from time to time, the "Credit Agreement") among
Phelps Dodge Corporation., a New York corporation (the "Borrower"), the Lenders
(as defined in the Credit Agreement) and Citibank, N.A., as agent for the
Lenders (the "Agent"). Terms defined in the Credit Agreement are used herein
with the same meaning.

         The "Assignor" and the "Assignee" referred to on Schedule I hereto
agree as follows:

         1. The Assignor hereby sells and assigns to the Assignee, and the
assignee hereby purchases and assumes from the Assignor, an interest in and to
the Assignor's rights and obligations under the Credit Agreement as of the date
hereof equal to the percentage interest specified on Schedule 1 hereto of all
outstanding rights and obligations under the Credit Agreement. After giving
effect to such sale and assignment, the Assignee's Commitment and the amount of
the Advances owing to the Assignee will be as set forth on Schedule 1 hereto.

         2. The Assignor (i) represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim; (ii) makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with the Credit Agreement
or the execution, legality, validity, enforceability, genuineness, sufficiency
or value of the Credit Agreement or any other instrument or document furnished
pursuant thereto; (iii) makes no representation or warranty and assumes no
responsibility with respect to the financial condition of the Borrower or the
performance or observance by the Borrower of any of its obligations under the
Credit Agreement or any other instrument or document furnished pursuant thereto;
and (iv) attaches the Revolving Credit Note, if any held by the Assignor.

         3. The Assignee (i) confirms that it has received a copy of the Credit
Agreement, together with copies of the financial statements referred to in
Section 4.1 thereof and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into this
Assignment and Acceptance; (ii) agrees that it will, independently and without
reliance upon the Agent, the Assignor or any other Lender and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under the Credit
Agreement; (iii) confirms that it is an Eligible Assignee; (iv) appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers and discretion under the Credit Agreement as are delegated to the


                                      C-1
<PAGE>


Agent by the terms thereof, together with such powers and discretion as are
reasonably incidental thereto; (v) agrees that it will perform in accordance
with their terms all of the obligations that by the terms of the Credit
Agreement are required to be performed by it as a Lender; and (vi) attaches any
U.S. Internal Revenue Service forms required under Section 2.13 of the Credit
Agreement.

         4. Following the execution of this Assignment and Acceptance, it will
be delivered (if required pursuant to Section 8.7 of the Credit Agreement) to
the Borrower for approval and to the Agent for acceptance and recording by the
Agent (provided that such acceptance and recording shall only be made if the
Borrower and the Agent have consented thereto to the extent required by Section
8.7 of the Credit Agreement). The effective date for this Assignment and
Acceptance (the "Effective Date") shall be the date of acceptance hereof by the
Agent, unless otherwise specified on Schedule 1 hereto.

         5. Upon such acceptance and recording by the Agent, as of the Effective
Date, (i) the Assignee shall be a party to the Credit Agreement and, to the
extent provided in this Assignment and Acceptance, have the rights and
obligations of a Lender thereunder and (ii) the Assignor shall, to the extent
provided in this Assignment and Acceptance, relinquish its rights and be
released from its obligations under the Credit Agreement.

         6. Upon such acceptance and recording by the Agent, from and after the
Effective Date, the Agent shall make all payments under the Credit Agreement and
the Revolving Credit Notes in respect of the interest assigned hereby (including
all payments of principal, interest and facility fees with respect thereto) to
the Assignee. The Assignor and Assignee shall make all appropriate adjustments
in payments under the Credit Agreement and the Revolving Credit Notes for
periods prior to the Effective Date directly between themselves.

         7. This Assignment and Acceptance shall be governed by, and construed
in accordance with, the laws of the State of New York.

         8. This Assignment and Acceptance may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement. Delivery of an executed
counterpart of Schedule 1 to this Assignment and Acceptance by telecopier shall
be effective as delivery of a manually executed counterpart of this Assignment
and Acceptance.

         IN WITNESS WHEREOF, the Assignor and the Assignee have caused Schedule
1 to this Assignment and Acceptance to be executed by their officers thereunto
duly authorized as of the date specified thereon.
