are designated the 9.375% Senior Notes due 2019, initially limited in aggregate principal amount to
$350,000,000. The Notes issued on the date hereof pursuant to the terms of this Indenture shall be
in an aggregate principal amount of $350,000,000, which amount shall be set forth in the Company
Order for the authentication and delivery of the Notes pursuant to Section 3.03 of the Base
Indenture. In addition, the Company may issue, from time to time in accordance with the provisions
of this Indenture, additional Notes having the same terms and conditions as the Notes issued on the
date hereof in all respects (except for the payment of interest accruing prior to the issue date of
such additional Notes), so that such additional Notes

4

 

shall be consolidated and form a single series with the Notes issued on the date hereof and
shall be governed by the terms of the Indenture.

          SECTION 2.02. Maturity. The principal amount of the Notes shall be due and payable on
June 1, 2019.

          SECTION 2.03. Form and Payment. The Notes shall be issued in substantially the form
set forth on Exhibit A hereto and shall have the terms set forth in such form and shall initially
be Global Securities for purposes of the Base Indenture. The Notes shall be issued in fully
registered book-entry form without coupons in denominations of $2,000 and integral multiples of
$1,000 in excess thereof.

          The Depositary in respect of the Notes represented by Global Securities shall be The
Depository Trust Company. The Global Securities representing the Notes shall be deposited with, or
on behalf of, the Depositary and shall be registered in the name of its nominee, Cede & Co. Except
as otherwise set forth in Section 3.05 of the Base Indenture, the Global Securities may be
transferred, in whole and not in part, only to another nominee of the Depositary or to a successor
of the Depositary or its nominee.

          The Trustee shall act as Paying Agent for the Notes. The Company may choose to pay interest
by mailing checks or making wire transfers. All money paid by the Company to any Paying Agent that
remains unclaimed at the end of two years after the amount is due to Holders shall be repaid to the
Company, subject to any applicable abandoned property laws. After such two-year period, Holders
may look only to the Company for payment and not to the Trustee, any other Paying Agent or anyone
else. The Company may also arrange for additional payment offices, and may cancel or change these
offices, including any use of the Trustee’s Corporate Trust Office. The Company may appoint and
change the Paying Agent without prior notice to the Holders.

          SECTION 2.04. Interest. Interest on the Notes shall accrue at the rate of 9.375% per

Date to which interest was paid or duly provided for. Interest on the Notes shall be payable

“Interest Payment Date”), to the Holders in whose names the Notes are registered at the
close of business on the May 15 and November 15 immediately preceding such Interest Payment Date
(each a “Regular Record Date”). Interest on the Notes shall be computed on the basis of a
360-day year comprised of twelve 30-day months.

          SECTION 2.05. No Sinking Fund. The provisions of Article XII of the Base Indenture
shall not be applicable to the Notes.

ARTICLE III

ADDITIONAL COVENANTS

          In addition to the covenants set forth in Article X of the Base Indenture, the Company also
covenants and agrees for the benefit of Notes, but not Securities of any other series, as follows:

          SECTION 3.01. Limitation on Liens. The Company shall not, and will not permit any of
its Domestic Subsidiaries, directly or indirectly, to issue, assume or guarantee any Debt if that
Debt is secured by any Lien upon any Principal Property (or portion thereof) of the Company or of
any Domestic Subsidiary of the Company or any shares of stock or Debt of any of its Domestic
Subsidiaries, whether owned on June 1, 2009 or thereafter acquired, without effectively securing
the Notes equally and ratably with that Debt, so long as such Debt is so secured. The foregoing
restriction does not apply to:

     (i) Liens on any property acquired, constructed or improved by the Company or any
Domestic Subsidiary of the Company after June 1, 2009, which are created or assumed
contemporaneously with or within three years after its acquisition, or completion of
construction or improvement (or within six months thereafter pursuant to a firm commitment
for financing arrangements entered into within that three-year period) to secure or provide
for the payment of the Purchase Price or cost thereof, or Liens existing on any property at
the time of its acquisition;

     (ii) Liens existing on any property, shares of stock or indebtedness acquired from a
Person merged with or into the Company or a Domestic Subsidiary of the Company after June 1,
2009;

     (iii) with respect to any corporation that becomes a Domestic Subsidiary of the Company
after June 1, 2009, Liens on property of, or shares of stock or indebtedness issued by, any
such corporation existing at the time it becomes a Domestic Subsidiary and not incurred in
connection with or in anticipation of such corporation becoming a Domestic Subsidiary;

     (iv) Liens to secure Debt of a Domestic Subsidiary owed to the Company or Debt of one
of the Domestic Subsidiaries of the Company owed to another Domestic Subsidiary of the
Company;

     (v) Liens in favor of governmental bodies to secure partial, progress, advance or other
payments pursuant to any contract or statute;

     (vi) any Lien existing on June 1, 2009; or

     (vii) Liens for the sole purpose of extending, renewing or replacing Debt, in whole or
in part, secured by any Lien referred to in the foregoing clauses (i) to (vi), inclusive;
provided, however, that the principal amount of Debt secured by that Lien
shall not exceed the principal amount of Debt so secured at the time of such extension,
renewal or

6

 

replacement, and that such extension, renewal or replacement shall be limited to the
property that secured the Lien so extended, renewed or replaced (plus improvements on such
property).

          The limitation on Liens described in this Section 3.01 shall not apply to the issuance,
assumption or guarantee by the Company or any Domestic Subsidiary of the Company of Debt secured by
a Lien which would otherwise be subject to the foregoing restrictions up to an aggregate amount
which, together with all other Debt of the Company and of the Domestic Subsidiaries of the Company
secured by Liens (not including Liens permitted under the foregoing exceptions) and the
Attributable Debt with respect to Sale and Leaseback Transactions existing at that time (other than
Sale and Leaseback Transactions in which the property involved would have been permitted to be
subject to a Lien under clause (i) above), does not exceed 10% of Consolidated Net Tangible Assets.

          SECTION 3.02. Limitation on Sale and Leaseback Transactions. The Company and the
Domestic Subsidiaries of the Company are prohibited from entering into Sale and Leaseback
Transactions unless:

     (i) the Company or such Domestic Subsidiary of the Company would be entitled to incur
Debt secured by a Lien on the Principal Property to be leased without equally and ratably
securing the Notes, pursuant to clauses (i) — (vii) under Section 3.01 above; or the
Attributable Debt with respect thereto would be an amount permitted under the last paragraph
of Section 3.01 above; or

     (ii) the Company or such Domestic Subsidiary of the Company shall, within 180 days of
the effective date of any such arrangement, apply an amount equal to the proceeds from such
Sale and Leaseback Transaction to the payment or other retirement of Debt that ranks senior
to or equal with the Notes (other than, in either case, Debt owed by the Company or any
Subsidiary), or to the purchase of other Principal Property.

          SECTION 3.03. Limitation on Guarantees. The Company and the Domestic Subsidiaries of
the Company are prohibited from entering into any agreement pursuant to which any such Domestic
Subsidiary of the Company guarantees the payment of Debt incurred by the Company without providing
that the Notes be equally and ratably guaranteed by such Domestic Subsidiary of the Company.

ARTICLE IV

REDEMPTION OF THE NOTES

          SECTION 4.01. Optional Redemption. The Company may redeem the Notes, at its option,
at any time in whole, or from time to time in part, at a price equal to the greater of:

     (i) 100% of the principal amount of the Notes to be redeemed, plus accrued interest to
the Redemption Date; or

7

 

     (ii) the sum of the present values of the remaining scheduled payments of principal and
interest on the Notes to be redeemed, exclusive of interest accrued to the date of
redemption, discounted to the date of redemption on a semi-annual basis (assuming a 360-day
year consisting of twelve 30-day months) at the applicable Treasury Rate plus 50 basis
points, plus, in each case, accrued interest to the Redemption Date.

          For purposes of determining the optional redemption price, the following definitions are
applicable:

          “Comparable Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining term (the
“Remaining Life”) of the Notes that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of the Notes.

          “Comparable Treasury Price” means, with respect to any Redemption Date, the average of
the Reference Treasury Dealer Quotations obtained by the Company for that Redemption Date, after
excluding the highest and lowest of such Reference Treasury Dealer Quotations, or, if the Company
is unable to obtain at least four such Reference Treasury Dealer Quotations, the average of all
Reference Treasury Dealer Quotations obtained by the Company.

          “Independent Investment Banker” means Citigroup Global Markets Inc. or J.P. Morgan
Securities Inc., and their respective successors, as selected by the Company or, if such firms are
unwilling or unable to select the applicable Comparable Treasury Issue, an independent investment
banking institution of national standing appointed by the Company.

          “Reference Treasury Dealer” means Citigroup Global Markets Inc., J.P. Morgan
Securities Inc. and their respective successors and at least two other primary U.S. government
securities dealers in New York City (each, a “Primary Treasury Dealer”) selected by the
Independent Investment Banker; provided, however, that if any of the foregoing
shall cease to be a Primary Treasury Dealer, the Company shall substitute therefor another Primary
Treasury Dealer.

          “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury
Dealer and any Redemption Date for the Notes, the average, as determined by the Company, of the bid
and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its
principal amount, quoted in writing to the Trustee by the Reference Treasury Dealer at 3:30 p.m.,
New York City time, on the third business day preceding the Redemption Date.

          “Treasury Rate” means, with respect to any Redemption Date, (i) the yield, under the
heading which represents the average for the immediately preceding week, appearing in the most
recently published statistical release designated “H.15(519)” or any successor publication which is
published weekly by the Board of Governors of the Federal Reserve System and which establishes
yields on actively traded United States Treasury securities adjusted to constant maturity under the
caption “Treasury Constant Maturities”, for the maturity corresponding to the Comparable Treasury
Issue (if no maturity is within three months before or after the Remaining

8

 

Life, yields for the two published maturities most closely corresponding to the Comparable
Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from
such yields on a straight line basis, rounded to the nearest month) or (ii) if such release (or any
successor release) is not published during the week preceding the calculation date or does not
contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of
the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such
Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding such
Redemption Date.

          SECTION 4.02. Purchase of Notes Upon a Change of Control Repurchase Event.   If a
Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem the
Notes as described under Section 4.01 above, the Company will be required to make an offer to each
Holder of the Notes to repurchase all or any part (in a principal amount of $2,000 and in integral
multiples of $1,000 in excess thereof) of that Holder’s Notes at a repurchase price (the
“Purchase Price”) in cash equal to 101% of the aggregate principal amount of the Notes
repurchased plus any accrued and unpaid interest on the Notes repurchased to, but not including,
the date of repurchase. Within 30 days following any Change of Control Repurchase Event or, at the
Company’s option, prior to any Change of Control, but after the public announcement of the Change
of Control, the Company will mail a notice to each Holder, with a copy to the Trustee, describing
the transaction or transactions that constitute or may constitute the Change of Control Repurchase
Event and offering to repurchase the Notes on the payment date specified in the notice (the
“Repurchase Date”), which date will be no earlier than 30 days and no later than 60 days
from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation
of the Change of Control, state that the offer to purchase is conditioned on a Change of Control
Repurchase Event occurring on or prior to the payment date specified in the notice. The Company
will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities
laws and regulations thereunder to the extent those laws and regulations are applicable in
connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event.
To the extent that the provisions of any securities laws or regulations conflict with the Change of
Control Repurchase Event provisions of the Notes, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached the Company’s obligations
under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

          On the Repurchase Date following a Change of Control Repurchase Event, the Company will, to
the extent lawful:

     (i) accept for payment all the Notes or portions of the Notes properly tendered
pursuant to the Company’s offer;

     (ii) deposit with the Paying Agent an amount equal to the aggregate Purchase Price in
respect of all the Notes or portions of the Notes properly tendered; and

     (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted,
together with an Officers’ Certificate stating the aggregate principal amount of Notes being
purchased by the Company.

9

 

          The Paying Agent will promptly deliver to each Holder of Notes properly tendered, the Purchase
Price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be
transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased
portion of any Notes surrendered.

          The Company will not be required to make an offer to repurchase the Notes upon a Change of
Control Repurchase Event if a third party makes such an offer in the manner, at the times and
otherwise in compliance with the requirements for an offer made by the Company and such third party
purchases all Notes properly tendered and not withdrawn under its offer.

          For purposes hereof, the following definitions are applicable:

          “Change of Control” means the occurrence of any one of the following:

     (i) the direct or indirect sale, lease, transfer, conveyance or other disposition
(other than by way of merger or consolidation), in one or a series of related transactions,
of all or substantially all of the assets of the Company and its Subsidiaries taken as a

another Rating Agency) shall be taken into account (e.g., with respect to S&P, a decline in
a rating from BB+ to BB, as well as from BB- to B+, will constitute a decrease of one gradation).

          “Rating Date” means the date that is 60 days prior to the earlier of (i) a Change of
Control or (ii) public notice of the occurrence of a Change of Control or of the intention by the

the ratings of the Notes by both Rating Agencies shall be decreased by one or more gradations

[REVERSE SIDE OF NOTE]

ALLEGHENY TECHNOLOGIES INCORPORATED

9.375% Senior Note due 2019

1. Principal and Interest.

          The Company promises to pay the principal of this Note on June 1, 2019.

          The Company promises to pay interest on the principal amount of this Note on each Interest
Payment Date, as set forth on the face of this Note, at the rate of 9.375% per annum.

          Interest will be payable semiannually (to the Holders of record of the Notes at the close of
business on each Regular Record Date, as set forth on the face of this Note, immediately preceding
the Interest Payment Date) on each Interest Payment Date, commencing December 1, 2009.

          Interest on this Note will accrue from the most recent date to which interest has been paid on
this Note (or, if there is no existing default in the payment of interest and if this Note is
authenticated between a Regular Record Date and the next Interest Payment Date, from such Interest
Payment Date) or, if no interest has been paid, from June 1, 2009. Interest will be computed on
the basis of a 360-day year of twelve 30-day months.

2. Indenture.

          This Global Security is one of a duly authorized issue of securities of the Company (herein
called the “Notes”) issued under the Indenture, dated as of June 1, 2009 (the “Base Indenture”),
between the Company and The Bank of New York Mellon, as Trustee, as supplemented by the First
Supplemental Indenture, dated as of June 1, 2009 (the “Supplemental Indenture”, and, together with
the Base Indenture, the “Indenture”), between the Company and The Bank of New York Mellon, as
Trustee. Capitalized terms used herein are used as defined in the Indenture unless otherwise
indicated. The terms of the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and
Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such
terms. To the extent permitted by applicable law, in the event of any inconsistency between the
terms of this Note and the terms of the Indenture, the terms of the Indenture will control.

          The Notes are general unsecured obligations of the Company. The Indenture limits the original
aggregate principal amount of the Notes to $350,000,000, but additional Notes may be issued
pursuant to the Indenture, and the originally issued Notes and all such additional Notes vote
together for all purposes as a single class.

 

 

3. Redemption and Repurchase; Discharge Prior to Redemption or Maturity.

          This Note is subject to redemption by the Company at any time, as further described in the
Indenture. There is no sinking fund or mandatory redemption applicable to this Note.

          If the Company deposits with the Trustee money or U.S. Government Securities sufficient to pay
the then Outstanding principal of, premium, if any, and accrued interest on the Notes to redemption
or maturity, the Company may in certain circumstances be discharged from the Indenture and the
Notes or may be discharged from certain of its obligations under certain provisions of the
Indenture.

4. Registered Form; Denominations; Transfer; Exchange.

          The Notes are in registered form without coupons in denominations of $2,000 principal amount
and any multiple of $1,000 in excess thereof. A Holder may register the transfer or exchange of
Notes in accordance with the Indenture. The Company or Security Registrar may require a Holder to
furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. Pursuant to the Indenture, there are certain periods during
which the Company will not be required to issue, register the transfer of or exchange any Note or
certain portions of a Note.

5. Defaults and Remedies.

          If an Event of Default (other than certain bankruptcy defaults), as defined in the Indenture,
occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the
Notes then Outstanding may declare all the Notes to be due and payable. If certain bankruptcy
defaults with respect to the Company occur and are continuing, the Notes automatically become due
and payable. Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture
or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the
Notes then Outstanding may direct the Trustee in its exercise of remedies.

6. Amendment and Waiver.

          Subject to certain exceptions, the Indenture and the Notes may be amended, or default may be
waived, with the consent of the Holders of a majority in principal amount of the Outstanding Notes.
Without notice to or the consent of any Holder, the Company and the Trustee may amend or
supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or
inconsistency.

7. Authentication.

          This Note is not valid until the Trustee signs the certificate of authentication on the other
side of this Note.

 

 

8. Abbreviations.

          Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM
(= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian) and U/G/M/A/ (= Uniform Gifts to
Minors Act).

charge.

Payment Date shall be postponed to the next succeeding Business Day and no interest on such payment

interest and principal shall be made on the next succeeding Business Day and no interest (or
Additional Interest) on such payment shall accrue for the period from and after the Stated Maturity
Date to such next succeeding Business Day. If a Fundamental Change Purchase Date falls on a day

time prior to the close of business on the Business Day immediately prior to the Fundamental Change
Purchase Date to withdraw such Fundamental Change Purchase Notice (in whole or in part) by delivery

          The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental
Change Purchase Notice or written notice of withdrawal thereof.

          On or before 11:00 a.m. (New York City time) on the Fundamental Change Purchase Date, the

acting as the Paying Agent, shall segregate and hold in trust) cash sufficient to pay the aggregate
Fundamental Change Purchase Price of the Notes to be purchased pursuant to Section 4.01. If the
Paying Agent holds, in accordance with the terms of this Supplemental Indenture, cash sufficient to

Fundamental Change Purchase Date, then (i) the Notes tendered for purchase and not withdrawn shall
cease to be Outstanding, and interest, including Additional Interest, if any, shall cease to accrue
on the Fundamental Change Purchase Date (whether or not book-entry transfer of such Notes is made
or whether or not the Note is delivered to the Paying Agent); and (ii) all other rights of the
Holders with respect to Notes tendered for purchase shall terminate on the Fundamental Change
Purchase Date (other than the right to receive the Fundamental Change Purchase Price upon delivery
or transfer of the Notes). Nothing herein shall preclude any withholding of tax required by law.

          A Fundamental Change Purchase Notice may be withdrawn, in whole or in part, by means of a

business on the Business Day immediately prior to the Fundamental Change Purchase Date. The notice
of withdrawal shall state:

     (i) the principal amount of the withdrawn Notes;

     (ii) if certificated Notes have been issued, the certificate numbers of the withdrawn
Notes, or if not certificated, the notice must comply with appropriate DTC, Clearstream
and/or Euroclear procedures; and

     (iii) the principal amount, if any, which remains subject to the Fundamental Change
Purchase Notice.

          If the Notes are certificated, the Paying Agent shall promptly return to the respective
Holders thereof any Notes with respect to which a Fundamental Change Purchase Notice has been
withdrawn in compliance with this Supplemental Indenture.

          (b) Notes Purchased in Part. Any Notes that are to be purchased only in part shall be
surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form

12

 

satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such
Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee or the
Authenticating Agent shall authenticate and deliver to the Holder of such Notes, without service
charge, a new Note or Notes, of any authorized denomination as requested by such Holder in
aggregate principal amount equal to, and in exchange for, the portion of the principal amount of
the Notes so surrendered which is not purchased.

          (c) Compliance with Securities Laws upon Purchase of Notes. In connection with any
offer to purchase, or purchase of, Notes under Section 4.01, the Company shall, to the extent
applicable, (a) comply with Rules 13e-4 and 14e-1 (and any successor provisions thereto) under the
Exchange Act; (b) file the related Schedule TO (or any successor schedule, form or report) under
the Exchange Act; and (c) otherwise comply with all applicable Federal and state securities laws.
To the extent that the provisions of any securities laws or regulations conflict with the
provisions of this Supplemental Indenture as described in this Article IV, compliance by the
Company with such laws and regulations shall not in and of itself cause a breach of the Company’s
obligations described in this Article IV.

          (d) Repayment to the Company. The Trustee and the Paying Agent shall return to the
Company any cash or property that remains unclaimed at the end of two years after the amount is due
to Holders, together with interest that the Trustee or Paying Agent, as the case may be, has
expressly agreed in writing to pay, if any, that is held by them for the payment of a Fundamental
Change Purchase Price; provided, however, that to the extent that the aggregate
amount of cash or property deposited by the Company pursuant to Section 4.02(b), as applicable,
exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof which the
Company is obligated to purchase as of the Fundamental Change Purchase Date, then promptly on and
after the second Business Day following the Fundamental Change Purchase Date, the Trustee and the
Paying Agent shall return any such excess to the Company together with interest that the Trustee or
Paying Agent, as the case may be, has expressly agreed in writing to pay, if any.

          (e) Officers’ Certificate. At least three Business Days (or such lesser period as
agreed to by the Trustee) before the Company Notice Date, the Company shall deliver an Officers’

principal amount, or any portion of their principal amount that is equal to $1,000 or an integral
multiple thereof, into shares of Common

13

 

Stock at the Conversion Rate in effect at the time of conversion. No payment or adjustment
shall be made for dividends on, or other distributions with respect to, any Common Stock, except as
expressly provided in this Article V.

          (a) Conversion Procedures. The following procedures shall apply to convert Notes:

     (i) in respect of a beneficial interest in a Global Security, a Beneficial Owner must
comply with the procedures of the Depositary for converting a beneficial interest in a
Global Security and, if required pursuant to Section 2.08(b), pay funds equal to interest
and Additional Interest payable on the next Interest Payment Date to which such Beneficial
Owner is not entitled, and if required, pay all taxes or duties, if any; and

     (ii) in respect of a certificated Note, the Holder must (A) complete and manually sign
the conversion notice on the back of the note, or a facsimile of the conversion notice;
(B) deliver such conversion notice, which is irrevocable, and the Note to the Conversion
Agent; (C) furnish appropriate endorsements and transfer documents as may be required by
the Conversion Agent; (D) if required pursuant to Section 5.02(c), pay all transfer or
similar taxes; and (E) if required pursuant to Section 2.08(b), pay funds equal to interest
and Additional Interest payable on the next Interest Payment Date to which such Holder is
not entitled.

          The date a Holder complies with the foregoing requirements is the “Conversion Date”
hereunder. At the Conversion Date the rights of the Holders of such converted Notes as Holders
shall cease, and the Person or Persons entitled to receive the shares of Common Stock issuable upon
conversion shall be treated for all purposes as the record holder or holders of such Common Stock
as and after such time. The Company shall issue and shall deliver at such office or agency a
certificate or certificates for the number of full shares of Common Stock issuable upon conversion,
together with payment in cash in lieu of any fractional shares, as provided in Section 5.01(b), by
the third Business Day immediately following the Conversion Date (the “Settlement Date”).
A Holder may convert a portion of its Notes only if the principal amount of such portion is $1,000
or an integral multiple thereof.

          In the case of any Note that is converted in part only, upon such conversion the Company shall
execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the
Company, a new Note or Notes of authorized denominations in aggregate principal amount equal to the
unconverted portion of the principal amount of such Note.

          If a Holder has already delivered a Fundamental Change Purchase Notice in connection with a
Fundamental Change, with respect to a Note, the Holder may not surrender that Note for conversion
until the Holder has validly withdrawn the Fundamental Change Purchase Notice in accordance with
this Supplemental Indenture.

14

 

          If more than one Note shall be surrendered for conversion at one time by the same Holder, the
number of full shares of Common Stock issuable upon conversion thereof shall be computed on the
basis of the aggregate principal amount of the Notes (or specified portions thereof) so
surrendered.

          (b) Cash Payments in Lieu of Fractional Shares. The Company shall not issue
fractional shares of Common Stock upon conversion of Notes. Instead the Company shall deliver
cash, rounded to the nearest whole cent, for such fractional shares based on the Last Reported Sale
Price of the Common Stock on the applicable Conversion Date.

          (c) Taxes on Conversion. If a Holder converts Notes, the Company shall pay any
documentary, stamp or similar issue or transfer tax due on the issuance of shares of Common Stock
upon such conversion; provided, however, the Holder shall pay any such tax which is
due because the Holder requests the shares of Common Stock to be issued in a name other than the
Holder’s name. The Conversion Agent may refuse to deliver the certificates representing the shares
of Common Stock being issued in a name other than the Holder’s name until the Conversion Agent
receives a sum sufficient to pay any tax which shall be due because the shares are to be issued in
a name other than the Holder’s name, but the Conversion Agent shall have no duty to determine if
any such tax is due. Nothing herein shall preclude any withholding of tax required by law.

          (d) Certain Covenants of the Company. (i) The Company shall, prior to issuance of
any Notes hereunder, and from time to time as may be necessary, reserve out of its authorized but
unissued Common Stock or shares of Common Stock held in treasury, sufficient number of shares of
Common Stock, free of preemptive rights, to permit the conversion of the Notes, calculated assuming
the maximum number of Additional Shares are issuable upon conversion of the Notes pursuant to
Section 5.04.

     (ii) All shares of Common Stock delivered upon conversion of the Notes shall be newly
issued shares or treasury shares, shall be duly and validly issued and fully paid and
nonassessable and shall be free from preemptive rights and free of any lien or adverse
claim.

     (iii) The Company shall endeavor to comply promptly with all applicable Federal and
state securities laws regulating the issuance and delivery of shares of Common Stock upon
the conversion of Notes.

     (iv) Before taking any action that would cause an adjustment increasing the
Conversion Rate to an amount that would cause the Conversion Price to be reduced below the
then par value per share of the Common Stock, if any, of the shares of Common Stock
issuable upon conversion of the Notes, the Company shall take all corporate action which
may, in the opinion of its counsel, be necessary in order that the Company may validly and
legally issue shares of such Common Stock at such adjusted Conversion Rate.

15

 

          SECTION 5.02. Adjustments to Conversion Rate. The Conversion Rate shall be adjusted
from time to time by the Company as described below, except that the Company shall not make any
adjustments to the Conversion Rate if Holders of the Notes participate (as a result of holding the
Notes, and at the same time as holders of the Common Stock participate) in any of the transactions
described in this Section 5.02 as if such Holders of the Notes held a number of shares of the
Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed
in thousands) of Notes held by such Holders, without having to convert their Notes.

          (a) If the Company issues shares of Common Stock as a dividend or distribution on shares of
Common Stock, or if the Company effects a share split or share combination, the Conversion Rate
shall be adjusted based on the following formula:

	 	 	 	 	 	 	 	 	 	 	 
	 
	 	CR1	 	=	 	CR0 x	 	OS1	 	 
	 
	 	 	 	 	 OS0	 	 

where,

CR0 = the conversion rate in effect immediately prior to the
Ex-Dividend Date of such dividend or distribution or the effective date of such
share split or combination, as applicable;

CR1 = the conversion rate in effect immediately after such Ex-Dividend
Date or effective date, as applicable;

OS0 = the number of shares of Common Stock outstanding immediately
prior to such Ex-Dividend Date or effective date, as applicable; and

OS1 = the number of shares of Common Stock outstanding immediately
prior to such Ex-Dividend Date or effective date, as applicable, after giving pro
forma effect to such dividend, distribution, share split or share combination.

          Such adjustment shall become effective immediately after 9:00 a.m., New York City time, on the
Business Day following the Record Date for such dividend or distribution, or the date fixed for
determination for such share split or share combination. The Company shall not pay any dividend or
make any distribution on shares of Common Stock held in treasury by the Company. If any dividend
or distribution of the type described in this Section 5.02(a) is declared but not so paid or made,
the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if
such dividend or distribution had not been declared.

          (b) If the Company distributes to holders of all or substantially all the Common Stock any
rights or warrants entitling them for a period of not more than 45 calendar days to subscribe for
or purchase shares of Common Stock at a price per share less than the average of the Last Reported
Sale Prices of the Common Stock for the 10 consecutive Trading-Day period ending on the Trading Day
immediately preceding

16

 

the date of announcement of such distribution, the Conversion Rate shall be adjusted based on the
following formula:

	 	 	 	 	 	 	 	 	 	 	 
	 
	 	CR1	 	=	 	CR0 x	 	OS0 + X	 	 
	 
	 	 	 	 	OS0 + Y	 	 

where,

CR0 = the Conversion Rate in effect immediately prior the Ex-Dividend
Date for such distribution;

CR1 = the Conversion Rate in effect immediately after such Ex-Dividend
Date;

OS0 = the number of shares of Common Stock outstanding immediately
after such Ex-Dividend Date;

X = the total number of shares of Common Stock issuable pursuant to such rights or
warrants; and

Y = the number of shares of Common Stock equal to the aggregate price payable to
exercise such rights or warrants divided by the average of the Last Reported Sale
Prices of Common Stock over the 10 consecutive Trading-Day period ending on the
Trading Day immediately preceding the date of announcement of the distribution of
such rights or warrants.

          Such adjustment shall be successively made whenever any such rights or warrants are issued and
shall become effective immediately after 9:00 a.m., New York City time, on the Business Day
following the date fixed for such determination. The Company shall not issue any such rights,
options or warrants in respect of shares of Common Stock held in treasury by the Company. To the
extent that shares of Common Stock are not delivered after the expiration of such rights or
warrants, or such rights or warrants are not exercised prior to their expiration, the Conversion
Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments
made upon the issuance of such rights or warrants been made on the basis of delivery of only the
number of shares of Common Stock actually delivered. If such rights or warrants are not so issued,
the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect
if such date fixed for the determination of stockholders entitled to receive such rights or
warrants had not been fixed.

          In determining whether any rights or warrants entitle the Holders to subscribe for or purchase
shares of Common Stock at less than such average Last Reported Sale Price, and in determining the
aggregate offering price of such shares of Common Stock, there shall be taken into account any
consideration received by the Company for such rights or warrants and any amount payable on
exercise or conversion thereof, the value of such consideration, if other than cash, to be
determined by the Company’s Board of Directors.

17

 

          (c) If the Company distributes shares of its capital stock, evidences of its indebtedness or
other assets or property of the Company to holders of all or substantially all the Common Stock,
excluding:

     (i) dividends or distributions and rights or warrants referred to in
Section 5.02(a) or (b) above;

     (ii) dividends or distributions paid exclusively in cash; and

     (iii) as described below in this Section 5.02(c) with respect to Spin-Offs,

then the Conversion Rate shall be adjusted based on the following formula:

	 	 	 	 	 	 	 	 	 	 	 
	 
	 	CR1	 	=	 	CR0 x	 	SP0	 	 
	 
	 	 	 	 	SP0 – FMV
	 	 

where,

CR0 = the Conversion Rate in effect immediately prior to the
Ex-Dividend Date for such distribution;

CR1 = the Conversion Rate in effect immediately after such Ex-Dividend
Date;

SP0 = the average of the Last Reported Sale Prices of Common Stock over
the 10 consecutive Trading-Day period ending on the Trading Day immediately
preceding the Ex-Dividend Date for such distribution; and

FMV = the Fair Market Value (as determined by the Company’s Board of Directors) of
the shares of capital stock, evidences of indebtedness, assets or property
distributed with respect to each outstanding share of Common Stock on the Record
Date for such distribution.

          Such adjustment shall become effective immediately prior to 9:00 a.m., New York City time, on
the Business Day following the date fixed for the determination of stockholders entitled to receive
such distribution. With respect to an adjustment pursuant to this clause (c) where there has been
a payment of a dividend or other distribution on the Common Stock in shares of capital stock of any
class or series, or similar equity interest, of or relating to a Subsidiary or other business unit
(a “Spin-Off”), the Conversion Rate in effect immediately prior to 5:00 p.m., New York City
time, on the effective date of such Spin-Off shall be increased based on the following formula:

	 	 	 	 	 	 	 	 	 	 	 
	 
	 	CR1	 	=	 	CR0 x	 	FMV0 + MP0	 	 
	 
	 	 	 	 	MP0
	 	 

18

 

where,

CR0 = the Conversion Rate in effect immediately prior to 5:00 p.m., New
York City time, on the Effective Date of the Spin-Off;

CR1 = the Conversion Rate in effect immediately after the effective
date of the Spin-Off;

FMV0 = the average of the Last Reported Sale Prices of the capital
stock or similar equity interest distributed to holders of Common Stock applicable
to one share of Common Stock over the first 10 consecutive Trading-Day period
from, and including, the effective date of the Spin- Off; and

MP0 = the average of the Last Reported Sale Prices of Common Stock over
the first 10 consecutive Trading-Day period from, and including, the effective
date of the Spin-Off.

          Such adjustment shall occur on the tenth Trading Day from, and including, the effective date
of the Spin-Off and shall be applied on a retroactive basis from, and including, the effective date
of the Spin-Off; provided, however, that in respect of any conversion occurring
prior to the effective date of the Spin-Off with respect to which the Settlement Date would occur
during the 10 Trading Days from, and including, the effective date of the Spin-Off, references with
respect to the Spin-Off to the consecutive Trading-Day period shall be deemed replaced with such
lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and the
Settlement Date in determining the applicable Conversion Rate.

          (d) (i) If any regular, quarterly cash dividend or distribution made to the holders of all or
substantially all of the Common Stock is in excess of $0.18 per share (the “Initial Dividend
Threshold”), the Conversion Rate shall be adjusted based on the following formula:

	 	 	 	 	 	 	 	 	 	 	 
	 
	 	CR1	 	=	 	CR0 x	 	SP0	 	 
	 
	 	 	 	 	SP0 – C	 	 

where,

CR0 = the Conversion Rate in effect immediately prior to the
Ex-Dividend Date for such dividend or distribution;

CR1 = the Conversion Rate in effect immediately after the Ex-Dividend
Date for such dividend or distribution;

SP0 = the Last Reported Sale Price of Common Stock on the Trading Day
immediately preceding the Ex-Dividend Date for such dividend or distribution; and

19

 

C = the amount in cash per share distributed by the Company to holders of Common
Stock in excess of the Initial Dividend Threshold.

          The Initial Dividend Threshold shall be adjusted at any time the Conversion Rate is adjusted
in a manner inversely proportional to adjustments to the Conversion Rate; provided that no
adjustment shall be made to the Initial Dividend Threshold for any adjustment made to the
Conversion Rate under this Section 5.02(d)(i).

     (ii) If the Company pays any cash dividend or distribution that is not a regular,
quarterly cash dividend or distribution to holders of all or substantially all of the
Common Stock, the Conversion Rate shall be adjusted based on the following formula:

	 	 	 	 	 	 	 	 	 	 	 
	 
	 	CR1	 	=	 	CR0 x	 	SP0	 	 
	 
	 	 	 	 	SP0
– C	 	 

     where,

CR0 = the Conversion Rate in effect immediately prior to the
Ex-Dividend Date for such dividend or distribution;

CR1 = the Conversion Rate in effect immediately after the Ex-Dividend
Date for such dividend or distribution;

SP0 = the Last Reported Sale Price of Common Stock on the Trading Day
immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C = the amount in cash per share distributed by the Company to holders of Common
Stock.

          (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender or
exchange offer for Common Stock, to the extent that the cash and value of any other consideration
included in the payment per share of Common Stock exceeds the Last Reported Sale Price of the
Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be
made pursuant to such tender or exchange offer (such last date, the “Expiration Time”), the
Conversion Rate shall be increased based on the following formula:

	 	 	 	 	 	 	 	 	 	 	 
	 
	 	CR1	 	=	 	CR0 x	 	AC +
(SP1 x OS1)	 	 
	 
	 	 	 	 	OS1 x SP1
	 	 

where,

CR0 = the Conversion Rate in effect immediately prior to the effective
date of the adjustment;

20

 

CR1 = the Conversion Rate in effect immediately after the effective
date of the adjustment;

AC = the aggregate value of all cash and any other consideration (as determined by
the Company’s Board of Directors) paid or payable for shares accepted for purchase
or exchange in such tender or exchange offer;

OS0 = the number of shares of Common Stock outstanding immediately
prior to the date such tender or exchange offer expires;

OS1 = the number of shares of Common Stock outstanding immediately
after the date such tender or exchange offer expires (after giving effect to the
reduction of shares accepted for purchase or exchange in such tender or exchange
offer); and

SP1 = the average of the Last Reported Sale Prices of Common Stock over
the 10 consecutive Trading-Day period commencing on the Trading Day next
succeeding the date such tender or exchange offer expires.

          Such adjustment shall occur on the tenth Trading Day from, and including, the Trading Day next
succeeding the date such tender or exchange offer expires and shall be applied on a retroactive
basis from, and including, the Trading Day next succeeding the date such tender or exchange offer
expires; provided, however, that in respect of any conversion occurring prior to
the date such tender or exchange offer expires with respect to which the Settlement Date would
occur during the 10 Trading Days from, and including, the Trading Day next succeeding the date such
tender or exchange offer expires, references with respect to the tender or exchange offer to the
10 consecutive Trading Day period shall be deemed replaced with such lesser number of Trading Days
as have elapsed between the Trading Day next succeeding the date such tender or exchange offer
expires and the Settlement Date in determining the applicable Conversion Rate.

          If the Company is obligated to purchase shares pursuant to any such tender or exchange offer,
but the Company is permanently prevented by applicable law from effecting any such purchases or all
such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate
that would then be in effect if such tender or exchange offer had not been made.

          Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of
shares of Common Stock or any securities convertible into or exchangeable for shares of Common
Stock or the right to purchase shares of Common Stock or such convertible or exchangeable
securities.

          (f) The Company may (but is not required to) increase the Conversion Rate to avoid or diminish
income tax to holders of Common Stock or rights to purchase Common Stock in connection with a
dividend or distribution of shares (or rights to acquire shares) or any similar event treated as
such for income tax purposes.

21

 

          (g) To the extent permitted by applicable law and the rules of any stock exchange or market
upon which the Common Stock is listed or admitted for trading, the Company may increase the
Conversion Rate by any amount for a period of at least 20 days if the Company’s Board of Directors
determines that such increase would be in the best interest of the Company, which determination
shall be conclusive.

          (h) Notwithstanding the foregoing provisions of this Section 5.02, the applicable Conversion
Rate will not be adjusted:

     (i) upon the issuance of any shares of Common Stock pursuant to any present or future
plan providing for the reinvestment of dividends or interest payable on the securities of
the Company and the investment of additional optional amounts in shares of Common Stock
under any plan;

     (ii) upon the issuance of any shares of Common Stock or options or rights to purchase
shares of Common Stock pursuant to any present or future employee, director or consultant
benefit plan or program of or assumed by the Company or any of its Subsidiaries;

     (iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant,
right, or exercisable, exchangeable or convertible security not described in clause (ii)
above and outstanding as of the Issue Date;

     (iv) for a change in the par value of the Common Stock; or

     (v) for accrued and unpaid interest (including Additional Interest, if any).

          (i) All calculations under this Section 5.02 shall be made by the Company and shall be made to
the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be.
The Company shall not be required to make an adjustment in the Conversion Rate unless the
adjustment would require a change of at least 1% in the Conversion Rate; provided,
however, that the Company shall carry forward any adjustments that are less than 1% of the
Conversion Rate that the Company elects not to make and take them into account upon the earlier of
(i) any conversion of Notes or (ii) such time as all adjustments that have not been made prior
thereto would have the effect of adjusting the Conversion Rate by at least 1%. Except as provided
in this Section 5.02 and Sections 5.03 and 5.04, the Company shall not adjust the Conversion Rate.

          (j) Whenever the Conversion Rate is adjusted as provided in this Supplemental Indenture, the
Company shall promptly file with the Trustee and any Conversion Agent other than the Trustee an
Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a
brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of
the Trustee shall have received at the Corporate Trust Office of the Trustee such Officers’
Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion
Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect.
Promptly after delivery of such certificate, the Company shall prepare a notice of such

22

 

adjustment
of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which such
adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate
to the Holder of each Note at such Holder’s last address appearing on the Security Register.
Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

          (k) In any case in which this Section 5.02 provides that an adjustment shall become effective
immediately after (i) an Ex-Dividend Date for an event, (ii) the date fixed for the determination
of a share split or combination pursuant to Section 5.02(a), or (iii) the Expiration Time for any
tender or exchange offer pursuant to Section 5.02(e), (each a “Determination Date”), the
Company may elect to defer until the occurrence of the applicable Adjustment Event (x) issuing to
the Holder of any Note converted after such Determination Date and before the occurrence of such
Adjustment Event, the Additional Shares of Common Stock or other securities issuable upon such
conversion by reason of the adjustment required by such Adjustment Event over and above the Common
Stock issuable upon such conversion before giving effect to such adjustment and (y) paying to such
Holder any amount in cash in lieu of such Additional Shares of Common Stock or other securities or
in lieu of any fraction pursuant to Section 5.01(b). For purposes of this Section 5.02, the term
“Adjustment Event” shall mean:

     (1) in any case referred to in clause (i) above, the occurrence of such event,

     (2) in any case referred to in clause (ii) above, the date any such dividend or
distribution is paid or made, and

     (3) in any case referred to in clause (iii) above, the date a sale or exchange of
Common Stock pursuant to such tender or exchange offer is consummated and becomes
irrevocable.

          (l) For purposes of this Section 5.02, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company but shall include shares
issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.
The Company shall not pay any dividend or make any distribution on shares of Common Stock held in
the treasury of the Company.

          (m) Whenever any provision of this Article V requires a calculation of an average of Last
Reported Sale Prices over a span of multiple days, the Company shall make appropriate adjustments
(determined in good faith by the Company’s Board of Directors) to account for any adjustment to the
Conversion Rate that becomes effective at any time during the period from which the average is to
be calculated. Such adjustments shall be effective as of the Effective Date of the adjustment to
the Conversion Rate.

          SECTION 5.03. Effect of Reclassification, Consolidation, Merger or Sale. (a)  If any
of the following events occur: (i) any recapitalization, reclassification or change of the Common
Stock (other than a subdivision or combination) as a result of

23

 

which the Common Stock would be
converted into, or exchanged for, stock, other securities or other property or assets (or any
combination thereof) or (ii) any statutory share exchange, consolidation or merger involving the
Company pursuant to which the Common Stock shall be converted into cash, securities or other
property (or any combination thereof) or any sale, lease or other transfer in one transaction or a
series of related transactions of all or substantially all of the consolidated assets of the
Company and its Subsidiaries, taken as a whole, to any Person (other than one or more of the
Subsidiaries of the Company) as a result of which the Common Stock shall be converted into cash,
securities or other property (or any combination thereof) (any such event or transaction, a
“Reorganization Event”), then the Company or the successor or purchasing Person, as the
case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the
Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing
that at the effective time of the Reorganization Event each Note shall be convertible into, with
respect to each $1,000 in principal amount of such Note, the kind and amount of shares of stock,
other securities or other property or assets (including cash or any combination thereof) that a
holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such
Reorganization Event would have owned or been entitled to receive upon such Reorganization Event
(the “Reference Property”). For purposes of the foregoing, the type and amount of
consideration that a holder of Common Stock would have been entitled to receive in the case of any
such Reorganization Event that causes the Common Stock to be converted into the right to receive
more than a single type of consideration (determined based in part upon any form of stockholder
election) shall be deemed to be the weighted average of the types and amounts of consideration
received by the holders of Common Stock that affirmatively make such an election. Such
supplemental indenture shall provide for provisions and adjustments which shall be as nearly
equivalent as may be practicable to the provisions and adjustments provided for in this Article V
and in Article IV of this Supplemental Indenture and in the definition of “Fundamental
Change” herein, as appropriate, as determined in good faith by the Company (which determination
shall be conclusive), to make such provisions apply to such other Person if different from the
original issuer of the Notes. If, in the case of any Reorganization Event, the cash, securities or
other property receivable thereupon by a holder of Common Stock includes cash, securities or other
property of a Person other than the successor or purchasing Person, as the case may be, in such
Reorganization Event, then such supplemental indenture shall also be executed by such successor or
purchasing Person, as the case may be, and shall contain such additional provisions to
protect the interests of the Holders of the Notes as the Company’s Board of Directors shall
reasonably consider necessary by reason of the foregoing.

          (b) The Company shall cause notice of the execution of any supplemental indenture required by
this Section 5.03 to be mailed to each Holder of Notes, at its address appearing on the Security
Register, within 20 calendar days after execution thereof. Failure to deliver such notice shall
not affect the legality or validity of such supplemental indenture.

          (c) The above provisions of this Section 5.03 shall similarly apply to successive
Reorganization Events.

24

 

          (d) None of the foregoing provisions shall affect the right of a Holder of Notes to convert
the Notes into shares of Common Stock as set forth in Section 5.02 prior to the effective time of
such Reorganization Event.

          SECTION 5.04. Adjustment upon Certain Fundamental Changes. (a)  If a Holder elects to
convert Notes at a time when a Fundamental Change has occurred, the Conversion Rate for such Notes
so converted shall be increased by an additional number of shares of Common Stock (the
“Additional Shares”) as described below. Any conversion of Notes shall be deemed to have
occurred in connection with such Fundamental Change only if (i) in the case of a Fundamental Change
described in clause (2) of the definition of Fundamental Change, such Notes are surrendered for
conversion from and after the date that is 30 Scheduled Trading Days prior to the anticipated
Effective Date of such Fundamental Change through and including the Business Day immediately
preceding the related Fundamental Change Purchase Date, or (ii) in the case of a Fundamental Change
described in clause (1) or (3) of the definition of Fundamental Change, such Notes are surrendered
for conversion from and after the Effective Date of such Fundamental Change through and including
the Business Day immediately preceding the related Fundamental Change Purchase Date. The Company
shall notify Holders and issue a press release (x) at least 30 Scheduled Trading Days prior to the
anticipated Effective Date of any Fundamental Change described in clause (2) of the definition of
Fundamental Change and (y) no later than five Business Days after the Effective Date of any other
Fundamental Change.

          (b) Upon surrender of Notes for conversion in connection with a Fundamental Change, the
Company shall deliver to a converting Holder shares of Common Stock, including Additional Shares,
in accordance with Section 5.04(e) below. If the consideration for the Common Stock in any
Fundamental Change described in clause (2) of the definition of Fundamental Change is comprised
entirely of cash, for any conversion of Notes following the Effective Date of such Fundamental
Change, the conversion obligation shall be calculated based solely on the “Stock Price” for
the transaction and shall be deemed to be an amount equal to the applicable Conversion Rate
(including any adjustment to the Conversion Rate described in this Section 5.04) multiplied by such
Stock Price. In such event, the conversion obligation shall be determined and paid to Holders in
cash on the third Business Day following the conversion date.

          (c) The number of Additional Shares by which the Conversion Rate shall be increased shall be
determined by reference to the table attached as Schedule A hereto, based on the date on which the
Fundamental Change occurs or becomes effective (the “Effective Date”) and the Stock Price
paid or deemed paid per share of Common Stock in the Fundamental Change. If a Holder elects to
convert its Notes prior to the Effective Date of any Fundamental Change, and the Fundamental Change
does not occur, such Holder shall not be entitled to an increased Conversion Rate in connection
with such conversion.

          (d) The Stock Prices set forth in the column headings of the table in Schedule A hereto and in
clauses (ii) and (iii) of the immediately succeeding paragraph

25

 

shall be adjusted as of any date on
which the Conversion Rate of the Notes is adjusted pursuant to Section 5.02. The adjusted Stock
Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by
a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment and
the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares
set forth in such table shall be adjusted in the same manner as the Conversion Rate as set forth in
Section 5.02.

          The exact Stock Prices and Effective Dates may not be set forth in the table in Schedule A, in
which case:

     (i) if the Stock Price is between two Stock Price amounts in the table or the
Effective Date is between two Effective Dates in the table, the number of Additional Shares
by which the Conversion Rate shall be increased shall be determined by a straight-line
interpolation between the number of Additional Shares set forth for the higher and lower
Stock Price amounts and the two dates, as applicable, based on a 365-day year;

     (ii) if the Stock Price is greater than $150.00 per share (subject to adjustment), no
Additional Shares shall be added to the Conversion Rate; and

     (iii) if the Stock Price is less than $32.15 per share (subject to adjustment), no
Additional Shares shall be added to the Conversion Rate.

          Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock
issuable upon conversion exceed 31.1041 per $1,000 principal amount of Notes, subject to
adjustments in the same manner as the Conversion Rate under Section 5.02.

          (e) Upon effectiveness of any Fundamental Change described under clause (2) of the definition
of Fundamental Change, the Notes will be convertible only into Reference Property, if applicable.
If the Company is required to increase the Conversion Rate for Notes converted in connection with
such Fundamental Change by Additional Shares as a result of the Fundamental Change, Notes so
surrendered for conversion shall be settled as follows: (i) if the date on which the Notes are
surrendered for conversion is prior to the third Trading Day immediately preceding the Effective
Date
of the Fundamental Change, the Company shall (A) deliver the amount of shares of Common Stock,
based on the Conversion Rate then in effect without regard to the number of Additional Shares to be
added to the Conversion Rate as described above in this Section 5.04, on the third Trading Day
immediately following the applicable Conversion Date; and (B) as soon as practicable following the
Effective Date of the Fundamental Change, deliver an amount of Reference Property equal to the
amount of Reference Property that would have been issuable in respect of the Additional Shares
pursuant to such Fundamental Change; and (ii) if the date on which the Notes are surrendered for
conversion is on or after the third Trading Day immediately preceding the Effective Date of the
Fundamental Change, the Company shall deliver an amount of Reference Property equal to the amount
of Reference Property that would have been

26

 

issuable upon conversion of the Notes immediately after
giving effect to the Fundamental Change based on the Conversion Rate as increased by the Additional
Shares on the Settlement Date.

          SECTION 5.05. Stockholder Rights Plan. To the extent that the Company has a rights
plan in effect upon conversion of the Notes into Common Stock, Holders that convert their Notes
shall receive, in addition to the Common Stock, the rights under the rights plan, unless prior to
any conversion, the rights have separated from the Common Stock, in which case, and only in such
case, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed
to all holders of Common Stock shares of the Company’s capital stock evidences of indebtedness or
assets as described in Section 5.02(b) above, subject to readjustment in the event of the
expiration, termination or redemption of such rights. In lieu of any such adjustment, the Company
may amend such applicable stockholder rights agreement to provide that upon conversion of the Notes
the Holders shall receive, in addition to the Common Stock issuable upon such conversion, the
rights which would have attached to such Common Stock if the rights had not become separated from
the Common Stock under such applicable stockholder rights agreement.

          SECTION 5.06. Trustee Adjustment Disclaimer. The Trustee has no duty to determine
when an adjustment under this Article V should be made, how it should be made or what it should be
or to otherwise calculate the Conversion Price, and shall be protected in relying upon an Officers’
Certificate with request to same. The Trustee has no duty to determine whether a supplemental
indenture under Section 5.03 need be entered into or whether any provisions of any supplemental
indenture are correct. The Trustee shall not be accountable for and makes no representation as to
the validity or value of any securities or assets issued upon conversion of Notes. The Trustee
shall not be responsible for the Company’s failure to make any cash payment or to issue, transfer
or deliver any shares of Common Stock or share certificates or other securities or property upon
the surrender of any Security for the purpose of conversion or otherwise comply with this
Article V. Each Conversion Agent (other than the Company or an affiliate of the Company) shall
have the same protection under this Section 5.06 as the Trustee.

ARTICLE VI

Events of Default and Remedies

          SECTION 6.01. Additional Events of Default. In addition to the Events of Default set
forth in Section 5.01 of the Base Indenture, each of the following shall also constitute Events of
Default:

     (i) a failure by the Company to convert the Notes in accordance with the provisions of
this Supplemental Indenture upon exercise of a Holder’s conversion right which default
shall continue for a period of three Business Days after there has been given, by
registered or certified mail, to the Company by the Trustee or 

27

 

by such Holder, a written
notice specifying such default or breach and requiring it to be remedied and stating that
such notice is a “Notice of Default” under this Supplemental Indenture;

     (ii) a failure by the Company to deliver a Company Notice when due;

     (iii) a failure by the Company to repurchase Notes of such series tendered for
repurchase following the occurrence of a Fundamental Change in accordance with Section 4.01
of this Supplemental Indenture; and

     (iv) a failure by the Company or any of its Subsidiaries to pay any indebtedness for
borrowed money, within any applicable grace period after final maturity or the acceleration
by the holders thereof, if the total amount of such indebtedness unpaid or accelerated
exceeds $50,000,000.

          SECTION 6.02. Exception to Remedies. Notwithstanding anything in this Supplemental
Indenture or the Base Indenture to the contrary, to the extent elected by the Company, the sole
remedy for an Event of Default relating to the failure by the Company to comply with the reporting
obligations set forth in Section 7.04 of the Base Indenture and for any failure to comply with the
requirements of Section 314(a)(1) of the Trust Indenture Act shall, for the first 120 days after
the occurrence of such an Event of Default, consist exclusively of the right of Holders to receive
additional interest on the Notes at an annual rate equal to 0.50% of the principal amount of the
Notes (the “Additional Interest”). If the Company so elects, such Additional Interest
shall be payable in the same manner and on the same dates as the stated interest payable on the
Notes. The Additional Interest shall accrue on all Outstanding Notes from and including the date
on which the Event of Default relating to the failure to comply with the reporting obligations in
the Base Indenture or the failure to comply with the requirements of Section 314(a)(1) of the Trust
Indenture Act first occurs to but not including the 120th day thereafter (or such earlier date on
which such Event of Default is cured or waived by the Holders of a majority in principal amount of
the Outstanding Notes). On such 120th day (or earlier, if the Event of Default relating to the
reporting obligations under the Base Indenture or the failure to comply with the requirements of
Section 314(a)(1) of the Trust Indenture Act is cured or waived by the Holders of a majority in
principal amount of the Outstanding Notes prior to such 120th day), such Additional Interest shall
cease to accrue and, if the Event of Default relating to reporting obligations or the failure
to comply with Section 314(a)(1) of the Trust Indenture Act has not been cured or waived prior to
such 120th day, the Notes shall be subject to acceleration as provided in the Base Indenture. The
provisions of this Section 6.02 shall not affect the rights of Holders of Notes in the event of the
occurrence of any other Event of Default. In the event the Company does not elect to pay the
Additional Interest upon an Event of Default in accordance with this Section 6.02, the Notes shall
be subject to acceleration as provided in the Base Indenture. In order to elect to pay the
Additional Interest on the Notes as the sole remedy during the first 120 days after the occurrence
of an Event of Default relating to the failure to comply with the reporting obligations in
Section 7.04 of the Base Indenture or the failure to comply with Section 314(a)(1) of the Trust
Indenture Act in accordance with this Section 6.02, the Company must notify all Holders of Notes,
the

28

 

Trustee and the Paying Agent of such election on or before the close of business on the date on
which such Event of Default first occurs, stating (i) the amount of such Additional Interest that
is payable and (ii) the date on which such Additional Interest is payable.

ARTICLE VII

Modification and Amendment

          SECTION 7.01. Modification and Amendment. (a)  In addition to the provisions set
forth in Section 9.01 and Section 9.02 of the Base Indenture, the Company and the Trustee may,
without the consent of the Holders, enter into one or more supplemental indentures to conform the
provisions of the Indenture or the Notes to the Description of the Notes provided in the final
prospectus supplement of the Company for the Notes dated May 27, 2009 and filed with the
Commission.

          (b) In addition to the provisions set forth in Section 9.01 and Section 9.02 of the Base
Indenture, without the consent of each Holder of an Outstanding Note affected thereby, the Company
and the Trustee may not:

     (i) make any change that adversely affects the conversion rights of any Note; or

     (ii) reduce the Fundamental Change Purchase Price of any Note or amend or modify in
any manner adverse to the holders of Notes the Company’s obligation to make such payment,
whether through an amendment or waiver of provisions in the covenants, definitions or
otherwise.

ARTICLE VIII

Miscellaneous

          SECTION 8.01. Ratification of Base Indenture. The Base Indenture, as heretofore
supplemented, as supplemented by this Supplemental Indenture, is in all
respects ratified and confirmed, and this Supplemental Indenture shall be deemed part of the
Base Indenture, as heretofore supplemented, in the manner and to the extent herein and therein
provided.

          SECTION 8.02. Application of Supplemental Indenture. The provisions of this
Supplemental Indenture shall take effect immediately upon its execution in accordance with
Section 9.04 of the Base Indenture; provided, however, that the provisions set
forth in this Supplemental Indenture shall apply only in respect of the Notes issued under this
Supplemental Indenture and not to any past or future series of Securities established under the
Base Indenture or any other supplemental indenture.

29

 

          SECTION 8.03. Trust Indenture Act Controls. If any provision hereof limits, qualifies
or conflicts with the duties imposed by Sections 310 through 317 of the Trust Indenture Act, the
imposed duties shall control.

          SECTION 8.04. Conflict with Base Indenture. To the extent not expressly amended or
modified by this Supplemental Indenture, the Base Indenture shall remain in full force and effect.
If any provision of this Supplemental Indenture relating to the Notes is inconsistent with any
provision of the Base Indenture, as heretofore supplemented, the provision of this Supplemental
Indenture shall control.

          SECTION 8.05. Withholding Offset. (a)  The Company (through the Withholding Agent or
otherwise) shall be entitled to reduce or otherwise set-off against any payments made or deemed
made by the Company to Holders in respect of the Notes or the Common Stock for any amounts the
Company believes it is required to withhold by law. For the avoidance of doubt, if the Company
pays any withholding taxes on behalf of a Holder as a result of an adjustment to the Conversion
Rate of the Notes, the Company may, at its option, set-off such payments against payments to such
Holder of cash and Common Stock in respect of the Notes. Any amounts withheld pursuant to this
Section 8.06 shall be paid over by the Company (through the Withholding Agent or otherwise) to the
appropriate taxing authority.

          (b) Prior to or upon the occurrence of any event that results in an actual or deemed payment
by the Company to Holders in respect of the Notes or the Common Stock, the Company (through the
Trustee, Paying Agent, Withholding Agent or otherwise) may request a Holder to furnish any
appropriate documentation that may be required in order to determine the Company’s withholding
obligations under applicable law (including, without limitation, a United States Internal Revenue
Service Form W-9, Form W-8BEN or Form W-8ECI, as appropriate).

          SECTION 8.06. Calculations in Respect of Notes. Except as otherwise provided herein,
the Company shall make all calculations called for in respect of the Notes. These calculations
include, but are not limited to, determinations of the Last Reported Sale Price, accrued interest
payable on the Notes and the Conversion Rate. The Company shall make all calculations in good
faith and, absent manifest error, such calculations shall be final and binding on the Holders. The
Company shall provide a schedule of its calculations to each of the Trustee and the Conversion
Agent, and each of
the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of such
calculations without independent verification. The Trustee shall forward the Company’s
calculations to any Holder upon such Holder’s request.

          SECTION 8.07. Governing Law. THIS SUPPLEMENTAL INDENTURE AND THE NOTES SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

          SECTION 8.08. Successors. All agreements of the Company in the Base Indenture, as
heretofore supplemented, this Supplemental Indenture and the Notes shall bind its successors.

30

 

          SECTION 8.09. Counterparts. This instrument may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.

          SECTION 8.10. Appointment of Conversion Agent. The Company hereby appoints the
Trustee as Conversion Agent, and the Trustee hereby accepts such appointment.

          SECTION 8.11. Trustee Disclaimer. The Trustee makes no representation as to the
validity or adequacy of this Supplemental Indenture or the Notes other than the Trustee’s
Certificate of Authentication. The recitals and statements herein and in the Notes are deemed to
be those of the Company and not the Trustee. The Trustee shall not be accountable for the use by
the Company of the proceeds of the Notes.

     Allegheny Technologies Incorporated, a corporation duly organized and existing under the laws
of Delaware (herein called the “Company”, which term includes any successor Person under
the Indenture hereinafter referred to), for value received, hereby promises to pay to [the order of
[                    ]] [if Global Securities, CEDE & CO.], or its registered assigns, the principal sum of
$[                                        ] ([                           
             ] Dollars) on June 1, 2014, and to pay interest thereon from
and including June 2, 2009 or from and including the most recent Interest Payment Date to which
interest has been paid or duly provided for, semi-annually on June 1 and December 1 in each year,

more Predecessor Securities) is registered at the close of business on the Regular Record Date for

may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or
duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and
may either be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Securities of this series 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

payment of public and private debts; provided, however, that at the option of the
Company payment of interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register; provided further,
however, that any such payment in respect of a Global Security shall be made by wire
transfer of same-day funds to the applicable Depositary.

     Reference is hereby made to the further provisions of this Security set forth on the reverse
hereof, which further provisions shall for all purposes have the same effect as if set forth at

Form of Reverse of Security.

1. Indenture

     This Security is one of a duly authorized issue of securities of the Company (herein called
the “Securities”), issued and to be issued in one or more series under an Indenture, dated
as of June 1, 2009 (the “Base Indenture”), as heretofore supplemented, include as
supplemented by the Second Supplemental Indenture, dated as of June 2, 2009 (the “Second
Supplemental Indenture”, and together with the Base Indenture as so supplemented, the
“Indenture”), between the Company and The Bank of New York Mellon, a New York banking
corporation, as Trustee (herein called the “Trustee”, which term includes any successor
trustee under the Indenture), to which Indenture reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of the Company, the
Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are
to be, authenticated and delivered. The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939.
Capitalized terms used but not defined herein shall have the meanings ascribed thereto in the
Indenture. If any provision of this Security is inconsistent with any provision of the Indenture,
the provision in the Indenture shall control. This Security is one of the series designated on the
face hereof.

     No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of (and premium, if any) and interest on this Security at the times, place and rate,
and in the coin or currency, herein prescribed.

2. No Optional Redemption; No Sinking Fund; No Defeasance and Covenant Defeasance

     The Securities are not subject to redemption at the election of the Company. The Securities
are not subject to a sinking fund or mandatory redemption. The Securities are not subject to
Article XIII of the Base Indenture.

     If a Fundamental Change occurs at any time, subject to the provisions set forth in the
Indenture, the Holder of this Security shall have the right, at such Holder’s option, to require
the Company to purchase all of such Security, or any portion of the principal amount thereof, that
is equal to $1,000 or an integral multiple thereof, at the Fundamental Change Purchase Price
specified in the Indenture. Article IV of the Second Supplemental Indenture sets forth the
procedures, obligation, conditions and other terms of such repurchase option upon the occurrence of
a Fundamental Change.

     Subject to the procedures for conversion set forth in Article V of the Second Supplemental

$1,000 or an integral multiple thereof, into shares of Common Stock at the Conversion Rate
then in effect at the time of conversion.

5. Amendment; Waiver

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities at any time by the Company and the Trustee with the consent of the Holders of a majority
in principal amount of the Securities at the time Outstanding. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount of the Securities at
the time Outstanding, on behalf of the Holders of all Securities, to waive compliance by the
Company with certain provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future Holders of this Security and of any Security
issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether
or not notation of such consent or waiver is made upon this Security.

6. Remedies

     As provided in and subject to the provisions of the Indenture, the Holder of this Security
shall not have the right to institute any proceeding with respect to the Indenture or for the
appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall
have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities, the Holders of not less than 25% in principal amount of the Securities at the time
Outstanding shall have made written request to the Trustee to institute proceedings in respect of
such Event of Default as Trustee and offered the Trustee reasonable indemnity and the Trustee shall
not have received from the Holders of a majority in principal amount of Securities at the time
Outstanding a direction inconsistent with such request, and shall have failed to institute any such
proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The
foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement
of any payment of principal hereof or any premium or interest hereon on or after the respective due
dates expressed herein.

7. Registered Form; Denominations; Transfer; Exchange

     As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Security is registrable in the Security Register, upon surrender of this Security
for registration of transfer at the office or agency of the Company in any Place of Payment, duly
endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company
and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

     The Securities are issuable only in registered form without coupons in denominations of $1,000
and any integral multiple thereof. As provided in the Indenture and subject to certain

 

 

6

limitations therein set forth, Securities are exchangeable for a like aggregate principal
amount of Securities and of like tenor of a different authorized denomination, as requested by the
Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or exchange, but the
Company or the Security Registrar may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in whose name this
Security is registered as the owner hereof for all purposes, whether or not this Security be
