Section 2.04 Installment Amount Cash or Stock Payment.

     (a) General. On each applicable Installment Date, the Company shall pay to each Holder the Installment Amount due on such Installment Date, at the Company’s option, in cash or Common Shares or any combination of cash and Common Shares, subject to the provisions of this Article II; provided, however, that no portion of the Installment Amount may be paid in Common Shares unless (A) the Equity Conditions are satisfied, or waived, as applicable, by the Trustee, at the direction of the Holders of a majority of the aggregate principal amount of the Notes then Outstanding, except that after the third Trading Day of the applicable Stock Payment Pricing Period, the failure of the Equity Condition described in clause (ix) of the definition of “Equity Conditions” to be satisfied may not be waived and (B) the Maximum Share Amount has not been exceeded.

     On a date not less than 11 Trading Days prior to each Installment Date (the “Installment Notice Date”), the Company shall deliver a written notice (a “Company Installment Notice”) to the Trustee and the Holders, which shall either: (i) confirm that the entire applicable Installment Amount shall be paid in cash; or (ii) (A) state that the Company elects to pay all or a portion of the Installment Amount in Common Shares, (B) specify the portion which the Company elects to pay in cash (such amount, the “Cash Payment Amount”) and the portion that the Company elects to pay in Common Shares (such portion a “Stock Payment Amount”), which amounts when added together must equal the applicable Installment Amount and (C) certify that the Equity Conditions are then satisfied (it being understood that the Trustee shall be relying conclusively on such certification). If (x) the Company does not timely deliver a Company Installment Notice in accordance with this Section 2.04(a) or (y) the Equity Conditions are not satisfied, then the Company shall be deemed to have delivered a Company Installment Notice electing to pay the entire Installment Amount in cash. Any Cash Payment Amount shall be paid in accordance with

Section 2.04(b) and any Stock Payment Amount shall be paid in accordance with Section 2.04(c). Each Company Installment Notice, whether actually given or deemed given, shall be irrevocable.

     (b) Mechanics of Cash Payment. On each Installment Date (in addition to any portion of the Installment Amount required to be paid in Common Shares pursuant to Section 2.04(c), if any): (i) to the extent that the Company elects to pay 50% or less of the applicable Installment Amount in cash, then the Company shall pay to each Holder an amount in cash equal to such percentage of the Installment Amount; or (ii) to the extent that the Company elects (or is deemed to have elected) to pay more than 50% of the applicable Installment Amount in cash (the amount by which the percentage of the Installment Amount the Company elects to pay in cash exceeds 50%, the “Additional Percentage”), then the Company shall pay to each Holder an amount in cash equal to the sum of (x) 50% of the Installment Amount and (y) the IA Additional Cash Payment if the Daily VWAP can be determined on each day of the Stock Payment Pricing Period or, if the Daily VWAP cannot be determined on each day of the Stock Payment Pricing Period, the IA Base Payment.

     The “IA Additional Cash Payment” shall be determined according to the following formula:

     For the purposes of the foregoing formula:

     IA= the IA Additional Cash Payment Amount.

     X = the Installment Amount payable on the applicable Installment Date.

     Y = the Stock Payment Price for the applicable Installment Date.

     Z = the highest Daily VWAP during the Stock Payment Pricing Period for the applicable Installment Date.

     P% = the Additional Percentage.

     The “IA Base Payment” shall be determined according to the following formula:

IB = 1.15 x X x P%

     For the purposes of the foregoing formula:

     IB = IA Base Payment

     X = the Installment Amount payable on the applicable Installment Date

     P% = the Additional Percentage.

     (c) Mechanics of Stock Payment. On each Installment Date, to the extent that the Company elects to pay all or any portion of the applicable Installment Amount in Common Shares, and the Daily VWAP can be determined on each day of the Stock Payment

Pricing Period, the applicable Stock Payment Amount shall be paid in a number of Common Shares equal to the Stock Payment Amount divided by the Stock Payment Price for such Installment Date. The Company shall deliver the Common Shares to be paid in accordance with the mechanics for delivery set forth in Section 2.05. To the extent that the aggregate number of Common Shares to be delivered to all of the Holders pursuant to Section 2.05 in respect of any individual Stock Payment Amount exceeds the Beneficial Ownership Limitation, then, in addition to delivery of the number of Common Shares that would not exceed the Beneficial Ownership Limitation, the Company shall pay to the Trustee on behalf of each Holder in lieu of such number of Common Shares that would exceed the Beneficial Ownership Limitation (such excess number of shares, the “Excess Shares”) an amount in cash equal to the portion of the Stock Payment Amount that would otherwise be payable in respect of the Excess Shares. Notwithstanding the foregoing:

     (i) if the Equity Conditions are neither (x) satisfied nor (y) waived, as applicable, by the Trustee at the direction of the Holders of a majority of the aggregate principal amount of the Notes then Outstanding, then the Company shall pay, not more than three Trading Days after the Installment Date, an amount in cash equal to the EC Payment, in lieu of such Stock Payment Amount;

     (ii) to the extent that the Maximum Share Amount would be exceeded by such Stock Payment Amount when aggregated with any Common Shares already issued in respect of the Notes, then that portion of such Stock Payment Amount that would not exceed the Maximum Share Amount shall be delivered to the Trustee on behalf of each Holder pursuant to Section 2.05, ratably based on the then-Outstanding principal amount of the Notes held by such Holder relative to the aggregate principal amount of the Notes then Outstanding, and the Company shall pay to the Trustee on behalf of such Holder, not more than three Trading Days after the Installment Date, an amount in cash equal to the EC Payment, in lieu of any remainder of such Stock Payment Amount; and

     (iii) if the Daily VWAP cannot be determined on each day of the Stock Payment Pricing Period, then the Company shall pay to the Trustee on behalf of the Holders the IA Non-Stock Base Payment in lieu of a Stock Payment Amount.

     The “EC Payment” shall be determined according to the following formula:

     For the purposes of the foregoing formula:

     EC= the EC Payment.

     X = the Stock Payment Amount (or, in the case that the Maximum Share Amount would be exceeded by such Stock Payment Amount when aggregated with Common Shares already issued in respect of the Notes, only that portion of the Stock Payment Amount that would exceed the Maximum Share Amount).

     Y = the Stock Payment Price for the applicable Installment Date.

     Z = the highest Daily VWAP during the Stock Payment Pricing Period for the applicable Installment Date.

     The “IA Non-Stock Base Payment” shall be determined according to the following formula:

NS = 1.15 x X x S%

     For the purposes of the foregoing formula:

     NS = IA Non-Stock Base Payment

     X = the Installment Amount payable on the applicable Installment Date

     S% = the percentage of the applicable Installment Amount that the Company elected to pay in Common Shares.

Section 2.05 Mechanics for Delivery of Shares. Not later than three Trading Days after any Installment Date (the “Delivery Date”), the Company or its designated agent for the Common Shares (the “Common Stock Transfer Agent”) shall instruct the Trustee to instruct DTC to credit such aggregate number of Common Shares to which the applicable Holder shall be entitled, free from any restrictive legend, to such Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian (“DWAC”) system. In connection with any such action, the Trustee shall be entitled to receive and be fully protected in relying upon written instructions from the Company.

     If such Common Shares are not delivered by the Delivery Date, the Company shall:

     (i) instruct the Trustee to instruct DTC to deliver such Common Shares to the applicable Holder’s or its designee’s balance account with DTC through the DWAC system not later than the fifth Trading Day after the Delivery Date, or at any time after the Delivery Date, but not later than the fifth Trading Day after the Delivery Date, pay in cash either the Delivery Failure Amount or, if the Daily VWAP cannot be determined on each day of the Stock Payment Pricing Period, the IA Non-Stock Base Payment applicable to such Common Shares.

The “Delivery Failure Amount” shall be determined according to the following formula:

For the purposes of the foregoing formula:

DFA = the Delivery Failure Amount.

X = the portion of the Stock Payment Amount in respect of Common Shares that the Company has failed to deliver to the Holder.

Y = the Stock Payment Price for the Installment Date in respect of such Stock Payment Amount.

Z = the highest Daily VWAP during the period commencing on the Installment Notice Date for the Installment Date in respect of such Stock Payment Amount and ending on the date that the Company pays to the Holder the Delivery Failure Amount.

and

     (ii) pay to the Trustee on behalf of the Holders, in cash, an amount per Trading Day for each Trading Day after the Delivery Date until such Delivery Failure Amount is paid in cash or such Common Shares are delivered to the applicable Holder’s or its designee’s balance account with DTC through the DWAC system, together with interest on such amount at a rate equal to the sum of (A) the lesser of 15% and the maximum applicable legal rate per annum, plus (B) 1% of the portion of the Stock Payment Amount in respect of Common Shares that the Company has failed to deliver to the Holder for each of the first five Trading Days after the Delivery Date and 2% of the portion of the Stock Payment Amount in respect of Common Shares that the Company has failed to deliver to the Holder for each Trading Day thereafter (which amount shall be paid as liquidated damages and not as a penalty).

     If any fractional Common Share otherwise would be issuable as a result of the issuance of Common Shares to pay principal, premium or interest due on the Notes, the Company shall calculate and pay to the Trustee on behalf of the Holders a cash adjustment in lieu of such fractional share at a rate equal to the Daily VWAP per share for the Common Shares for the five Trading Days immediately preceding the first Trading Day prior to the applicable Installment Date.

Section 2.06 Issuance Limitations. The total number of Common Shares issued or issuable on any Installment Date in payment of principal, premium and interest on the Notes (including payment of interest on the Notes for purposes of any such rule or regulation) shall not (when aggregated with any Common Shares already issued in respect of the Notes) exceed the maximum number of Common Shares which the Company can so issue pursuant to any rule or regulation of the New York Stock Exchange (or any other principal United States securities market on which the Common Shares trade) (the “Maximum Share Amount”), subject to equitable adjustments from time to time for stock splits, stock dividends, combinations, capital reorganizations and similar events relating to the Common Shares occurring after the original issue date of the Notes. The limitation set forth in this Section 2.06 shall not apply if the issuances of Common Shares in lieu of cash are Permitted Issuances. In no event shall the Trustee be responsible for monitoring such issuance limitations.

Section 2.07 Other Terms of the Notes.

     (a) Except as provided in this First Supplemental Indenture, the Notes shall not be subject to redemption, repurchase or repayment at the option of the Company or any Holder thereof.

     (b) Article 10 of the Base Indenture shall not apply to this First Supplemental Indenture or the Notes.

     (c) Except as provided herein, the Holders of the Notes shall have no special rights in addition to those provided in the Base Indenture upon the occurrence of any particular events.

     (d) The Notes are not convertible into Common Shares or other securities of the Company.

ARTICLE III.

COVENANTS

Section 3.01 Covenants.

     For so long as any Notes are Outstanding, without the consent of the Holders of a majority in aggregate principal amount of the Notes then Outstanding:

     (a) Corporate Existence. The Company shall maintain in full force and effect its corporate existence, rights and franchises and all licenses and other rights to use property owned or possessed by it and reasonably deemed to be necessary to the conduct of its business.

     (b) Regulatory Compliance. If any Common Shares to be reserved for the purpose of paying Installment Amounts require registration or listing with or approval of any governmental authority, stock exchange or other regulatory body under any federal or state law or regulation before such shares may be validly issued or delivered in connection with a payment of an Installment Amount, the Company, at its sole cost and expense, in good faith and as expeditiously as possible, shall use its best efforts to secure such registration, listing or approval, as the case may be.

     (c) Issue Taxes. The Company shall pay all issue and other taxes, excluding federal, state or local income taxes, that may be paid in respect of its issue or delivery of Common Shares in accordance with the Notes.

     (d) Equal Treatment of Holders. No consideration shall be offered or paid to any Holder to amend or waive or modify any provision of the Notes, the Base Indenture or this First Supplemental Indenture unless the same consideration is also offered to all of the Holders. This provision constitutes a separate right granted to each Holder by the Company and shall not in any way be construed as the Holders acting in concert or as a group with respect to the purchase, disposition or voting of securities or otherwise.

     (e) Ranking. The Notes will be the general senior unsecured obligations of the Company and will rank in right of payment:

     (i) equally among themselves and with all other existing and future obligations of the Company that are unsecured and unsubordinated;

     (ii) senior to any future subordinated Indebtedness of the Company;

     (iii) effectively junior to any existing and future secured Indebtedness of the Company to the extent of the value of the collateral securing such Indebtedness; and

     (iv) structurally subordinated to the Indebtedness and other liabilities of the Subsidiaries.

     Notwithstanding any other paragraph of this Section 4.01 or the Base Indenture, and without limitation of (i) the remedies of a Holder pursuant to Article II in the event of a failure to deliver Common Shares or (ii) the right of a Holder pursuant to Section 2.04(c)(i) to receive an amount in cash equal to the EC Payment in lieu of a Stock Payment Amount in the event that the Equity Conditions are neither satisfied nor waived, any failure to perform, or breach of, any covenant or agreement of the Company in respect of the Notes contained in Section 314(a)(1) of the Trust Indenture Act shall not be a default or an Event of Default. Except as set forth in this First Supplemental Indenture, remedies against the Company for any such failure or breach will be limited to liquidated damages as described in the following sentence, and Holders shall not have any right to accelerate the maturity of the Notes as a result of any such failure or breach. Instead, if there is such a failure or breach of the Company’s obligation under Section 314(a)(1) of the Trust Indenture Act and continuance of such failure or breach for a period of 60 days after the date on which there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the then-Outstanding Notes, a written notice specifying such failure or breach and requiring it to be remedied and stating that such notice is a “Notice of Reporting Noncompliance” hereunder, the Company will pay liquidated damages to all Holders of Notes, at a rate per year equal to 0.25% of the outstanding principal amount of such Notes from the 60th day following such notice to and including the 150th day following such notice and at a rate per year equal to 0.5% of the principal amount of such Notes from and including the 151st day following such notice, until such failure or breach is cured. Any such liquidated damages shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. In the event that the Company is required to pay such liquidated damages, the Company shall provide a written notice to the Trustee (and if the Trustee is not the Paying Agent, the Paying Agent) no later then five

Business Days prior to the payment date for the payment of such liquidated damages setting forth the amount of such liquidated damages to be paid by the Company on such payment date and directing the Trustee (or, if the Trustee is not the Paying Agent, the Paying Agent) to make such payment to the extent it receives funds from the Company to do so. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine whether such liquidated damages are payable, or with respect to the nature, extent or calculation of the amount of liquidated damages owed.

     If an Event of Default occurs under clause (f) or (g) above, the principal of and interest on the Notes shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of Notes.

     If an Event of Default (other than an Event of Default occurring as a result of clause (f) or (g)) with respect to Notes shall have occurred and be continuing, either the Trustee or the Holders of not less than 25% in aggregate principal amount of Notes then Outstanding by written notice to the Company may declare the principal amount of all Notes and accrued and unpaid interest thereon to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable. This provision, however, is subject to the condition that if at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the amounts due shall have been obtained or entered as hereinafter provided, the Company shall have paid or deposited with the Trustee sufficient funds to pay all matured installments of interest, if any, upon all the Notes and the principal of the Notes and any other amounts that shall have become due (including, without limitation, any IA Base Payment, IA Additional Cash Payment, EC Payment, IA Non-Stock Base Payment, Delivery Failure Amount, EOD Cash Payment Amount, EOD Base Payment, CR Base Payment, CR Cash Payment Amount or liquidated damages) other than by such acceleration (with interest upon such principal and other amounts and, to the extent that payment of such interest is enforceable under applicable law, upon overdue installments of interest, at the rate borne by the Notes to the date of such payment or deposit) and all other defaults under this First Supplemental Indenture, other than the nonpayment of the principal of Notes that shall have become due by such acceleration, shall have been remedied, then and in every such case the Holders of a majority in aggregate principal amount of the Notes then Outstanding, by written notice to the Company and to the Trustee, may waive all defaults and rescind and annul such declaration and its consequences; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or shall impair any right consequent thereon.

     Subject to the provisions of Article 6 of the Base Indenture, in case an Event of Default with respect to the Notes shall occur and be continuing, the Trustee shall not be under any obligation to exercise any of the trusts or powers vested in it hereby at the request or direction of any Holder, unless such Holder shall have offered to such Trustee security or indemnity satisfactory to it.

     Upon the date of any acceleration of the amounts due and payable under the Notes in accordance with this Section 4.01 (an “Acceleration Date”), the Company shall deliver to the Trustee on behalf of the Holders by wire transfer of immediately available funds an amount in cash equal to the arithmetic average of the entire amount due and payable under the Notes and, if the Daily VWAP can be determined on each day of the Stock Payment Pricing Period, the EOD

Cash Payment Amount or, if the Daily VWAP cannot be determined on each day of the Stock Payment Pricing Period, the EOD Base Payment.

     The “EOD Cash Payment Amount” shall be determined according to the following formula:

For the purposes of the foregoing formula:

EOD = the EOD Cash Payment Amount.

X = the entire outstanding principal amount of the Notes, all interest on the outstanding principal amount of the Notes due through the Maturity Date and all other amounts due under the Notes.

Y = the Stock Payment Price for the Acceleration Date.

Z = the highest Daily VWAP during the Stock Payment Pricing Period for the Acceleration Date.

The “EOD Base Payment” shall be determined according to the following formula:

EODB = X x 1.15

For purposes of the foregoing formula:

EODB = the EOD Base Payment

X = the entire outstanding principal amount of the Notes, all interest on the outstanding principal amount of the Notes due through the Maturity Date and all other amounts due under the Notes.

Section 4.02 Collection of Indebtedness by Trustee; Trustee May Prove Debt. For purposes of this First Supplemental Indenture and the Notes, the reference to “30 days” in the first sentence of Section 5.02 of the Base Indenture shall be replaced with “five Business Days.”

Limitation on Suits by Holders. No Holder of any Note shall have any right, by virtue or by availing of any provision of this Indenture, to institute any action or proceeding at law or in equity or in bankruptcy or otherwise with respect to this Indenture, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof and the Holders of not less than 25% in aggregate principal amount of the Notes then Outstanding shall have made written request upon the Trustee to institute such action or proceedings in its own

name as trustee hereunder and shall have offered to the Trustee security or indemnity satisfactory to it as it may require, against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee for 45 days after its receipt of such notice, request and offer of security or indemnity shall have failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee during such 45-day period by Holders of a majority in principal amount of the Notes then Outstanding; it being understood and intended, and being expressly covenanted by the Holder of every Note with every other Holder of a Note and the Trustee, that no one or more Holders of Notes shall have any right in any manner whatever, by virtue or by availing of any provision of this Indenture, to affect, disturb or prejudice the rights of any other such Holder of Notes, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Notes (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

Y = the Stock Payment Price for the Redemption Date.

Z = the highest Daily VWAP during the Stock Payment Pricing Period for the Redemption Date.

     (b) Upon a Change of Control as a result of which the worldwide market value of the Company’s outstanding Common Shares held by non-affiliates is more than 10% less, immediately following the transaction or event that caused such Change of Control, than the worldwide market value of the Company’s outstanding Common Shares held by non-affiliates was immediately prior to such transaction or event (such a Change of Control a “Repurchase Offer Change of Control”), each Holder shall have the right to require that the Company repurchase all or any part of such Holder’s Notes at a purchase price in cash equal to 100% of the outstanding principal amount of the Notes and all interest payable through the date of such repurchase (such amount, the “Repurchase Price” and such date, the “Repurchase Date”), subject (in the event that there is an Installment Date having a record date prior to the date the Change of Control Offer is mailed) to the right of Holders of record on such record date to receive the Installment Amount due on such Installment Date; provided, however, that notwithstanding the occurrence of a Change in Control, the Company shall not be obligated to purchase the Notes pursuant to this Section 5.01(b) in the event that it has mailed Notice of Redemption of the Notes pursuant to Section 5.01(a).

     (c) Within 30 days following any Repurchase Offer Change of Control (except as provided in the proviso to Section 5.01(b)), the Company shall mail a notice to each Holder with a copy to the Trustee (the “Change of Control Offer”) stating:

     (1) that a Repurchase Offer Change of Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s Notes at the Repurchase Price (which shall be set forth in such notice) in cash, subject (in the event that there is an Installment Date having a record date prior to the date the Change of Control Offer is mailed) to the right of Holders of record on such record date to receive the Installment Amount due on such Installment Date;

     (2) the circumstances and relevant facts and financial information regarding such Repurchase Offer Change of Control;

     (d) Holders electing to have Notes purchased shall be required to surrender such Notes, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the purchase date. Any Holder shall be entitled to withdraw its election if the Trustee or the Company receives not later than one Business Day prior to the purchase date a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes which were delivered for purchase by the Holder and a statement that such Holder is withdrawing its election to have such Notes purchased. Notwithstanding the foregoing, Holders of Notes represented by an interest in the Global Notes shall tender their Notes in accordance with applicable procedures of DTC.

     (e) On the Repurchase Date, all Notes purchased by the Company under this Section shall be delivered to the Trustee for cancellation, and the Company shall pay the Repurchase Price, if any, to the Holders entitled thereto.

     (f) Notwithstanding the foregoing provisions of this Section, the Company will not be required to make a Change of Control Offer upon a Repurchase Offer Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in Section 5.01(c) applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

          (g) The Company shall advise the Trustee promptly of any Change of Control and whether it is a Repurchase Offer Change of Control.

          (h) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section.

          COEUR D’ALENE MINES CORPORATION, an Idaho corporation (the “Company”), hereby promises to pay to Cede & Co. or registered assigns the principal amount of One Hundred Million United States Dollars ($100,000,000) in equal quarterly installments as hereafter provided ending on December 31, 2012 (the “Maturity Date”), together with interest thereon at a rate of six and one-half percent (6.5%) per annum, from February 5, 2010 or from the most recent Installment Date to which interest has been paid or duly provided for, quarterly on the same dates on which installments of principal are due. Quarterly installments of principal and interest are due on March 31, June 30, September 30 and December 31 of each year, commencing March 31, 2010 (each, an "Installment Date”). The principal and interest so payable, and punctually paid or duly provided for, on any Installment Date will, as provided in the Indenture (as defined on the reverse hereof), be paid to the Person in whose name this Note (or one or more predecessor Notes) is registered at 5:00 p.m., New York time, on the record date for such interest, which shall be March 15, June 15, September 15 or December 15, (whether or not a Business Day), as the case may be, next preceding such Installment Date (each, the “Record Date” for the applicable Installment Date). Any such principal or interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Record Date and may either be paid to the Person in whose name this Note (or one or more predecessor Notes) is registered at 5:00 p.m., New York time, on a special record date for the payment of such defaulted interest to be fixed by the Trustee (as defined on the reverse hereof), notice whereof shall be given to Holders not less than 10 days prior to such special record date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture.

          Interest on this Note shall be computed on the basis of a 360-day year of twelve (12) thirty (30)-day months. If an Installment Date is not a Business Day, payment will be made on the next succeeding Business Day, and no additional interest will accrue in respect of such payment by virtue of the payment being made on such later date. Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

          This Note shall be deemed to be a contract made under the laws of the State of New York, and for all purposes shall be governed by and construed in accordance with the laws of said State.

          The holder hereof takes this Note subject to the terms and conditions of the Indenture.

          Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.
