 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 September 30, 1993 (herein, as supplemented by the First Supplemental Indenture dated January 25, 2007 between the Company and the
Trustee (as defined below), called the “Indenture”), between the Company and The Bank of New York Trust Company, N.A., as successor to J. P. Morgan Trust Company, National Association (formerly Chase Manhattan Trust Company, National
Association), as successor trustee to PNC Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto
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. This Security is one of the series designated on the face hereof, initially issued in the aggregate principal amount of (U.S.) $750,000,000. 
 The Securities of this series are subject to redemption, as a whole or in part, at the option of the Company, at any time or from time to time, on at least 30 days, but not more than 60 days, prior notice to the
Holders of the Securities of this series given as described below, at a redemption price equal to the greater of: 
  

	 	•	 	 100% of the principal amount to be redeemed, plus accrued interest, if any, to the redemption date; or 


  

	 	•	 	 the sum of the present values of the Remaining Scheduled Payments, as defined below, discounted, on a semiannual basis, assuming a 360-day year consisting of twelve
30-day months, at the Treasury Rate, as defined below, plus 15 basis points, plus accrued interest to the date of redemption which has not been paid. 


 “Treasury Rate” means, with respect to any redemption date: 
  

	 	•	 	 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; provided that if no maturity is within three months before or after the maturity date for this Security, yields for
the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight line basis rounding to the nearest month; or



  

	 	•	 	 if that 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 semiannual 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 that
redemption date. 


 The Treasury Rate will be calculated on the third business day preceding the redemption date. 
  

 4 








 “Comparable Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining term of this Security to be redeemed 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 this Security. 
 “Independent Investment Banker” means
one of the Reference Treasury Dealers, to be appointed by the Company. 
 “Comparable Treasury Price” means, with respect to any
redemption date for this Security: 
  

	 	•	 	 the average of four Reference Treasury Dealer Quotations for the redemption date, after excluding the highest and lowest of such Reference Treasury Dealer
Quotations; or 


  

	 	•	 	 if the Trustee obtains fewer than four Reference Treasury Dealer Quotations, the average of all quotations obtained by the Trustee. 


 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as
determined by the Trustee, 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 such Reference Treasury Dealer at 3:30 p.m., New York City
time, on the third business day preceding such redemption date. 
 “Reference Treasury Dealer” means each of Citigroup Global
Markets Inc, Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and J.P. Morgan Securities Inc., and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities
dealer, which we refer to as a “Primary Treasury Dealer,” the Company will substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer. 
 “Remaining Scheduled Payments” means, with respect to each Security to be redeemed, the remaining scheduled payments of the principal thereof
and interest thereon that would be due after the related redemption date but for such redemption; provided, however, that, if such redemption date is not an interest payment date with respect to such Security, the amount of the next succeeding
scheduled interest payment thereon will be deemed to be reduced by the amount of interest accrued thereon to such redemption date. 
 In the
event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 Notice of redemption will be given by mail to Holders of Securities of this series, not less than 30 nor more than 60 days prior to the date fixed for
redemption, all as provided in the Indenture. 
 If a Change of Control Repurchase Event occurs and this Security has not been previously
redeemed, the Company will make an offer to each Holder of Securities of this series to repurchase all or any part (in integral multiples of $1,000) of that Holder’s Securities of this series at a 

  

 5 








 
repurchase price in cash equal to 101% of the aggregate principal amount of Securities of this series repurchased plus any accrued and unpaid interest on the
Securities of this series repurchased to, but not including, the date of repurchase. Within 30 days following any Change of Control Repurchase Event or, at the option of the Company, 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
Securities of this series on the payment date specified in the notice, 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. To the extent that the provisions of any securities laws or regulations
conflict with the Change of Control Repurchase event provisions of this Security, the Company may comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control
Repurchase Event provisions of this Security by virtue of such conflict. 
 On the repurchase date following a Change of Control Repurchase
Event, the Company will, to the extent lawful: 
  

	 	(1)	accept for payment all Securities of this series or portions of Securities of this series properly tendered pursuant to its offer; 

  

	 	(2)	deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Securities of this series or portions of Securities of this series properly tendered;
and 

  

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

 The Paying Agent will promptly mail to each Holder of
Securities of this series properly tendered the purchase price for the Securities of this series, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Security of this series equal in
principal amount to any unpurchased portion of any Securities of this series surrendered; provided that each new Security of this series will be in a principal amount of $100,000 and integral multiples of $1,000 in excess thereof. 
 The Company will not be required to make an offer to repurchase the Securities of this series 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 Securities of this series properly tendered and not withdrawn under such offer.

 “Below Investment Grade Ratings Event” means that on any day within the 60-day period (which period shall be extended so long as
the rating of the Securities of this Series is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) after the earlier of (1) the occurrence of a Change of Control; or (2) public notice of the
occurrence of a Change of Control or the intention by the Company to effect a Change of Control, the Securities of this series are rated below Investment Grade by each of the Rating Agencies. Notwithstanding the foregoing, a Below Investment Grade
Ratings Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a 

  

 6 








 
Below Investment Grade Ratings Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the
reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of
or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Ratings Event). 
 “Change of Control” means the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which
is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act), other than the Company, its subsidiaries, or its or such subsidiaries’ employee benefit plans, becomes the beneficial owner (as defined in Rules
13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the Company's Voting Stock or other Voting Stock into which the Company's Voting Stock is reclassified, consolidated, exchanged or
changed measured by voting power rather than number of shares. 
 “Change of Control Repurchase Event” means the occurrence of both
a Change of Control and a Below Investment Grade Ratings Event. 
 “Fitch” means Fitch Ratings Ltd. 
 “Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s);
a rating of BBB- or better by S&P or Fitch (or its equivalent under any successor rating categories of S&P and Fitch); and the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by the
Company. 
 “Moody’s” means Moody’s Investors Service Inc. 
 “Rating Agency” means (1) each of Moody’s, S&P and Fitch; and (2) if any of Moody’s, S&P or Fitch ceases to rate
the Securities of this series or fails to make a rating of the Securities of this series publicly available for reasons outside of the control of the Company, a “nationally recognized statistical rating organization” within the meaning of
Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, selected by the Company (as certified by a resolution of the Board of Directors) as a replacement agency for Moody’s, S&P or Fitch, or all of them, as the case may be. 
 “S&P” means Standard & Poor’s Ratings Services, a division of McGraw-Hill, Inc.

capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person. 
 If
an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The provisions relating to defeasance and discharge set forth in Section 1302 of the Indenture and covenant defeasance set forth in
Section 1303 of the Indenture are applicable to the Securities of this series. 
 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 

  

 7 








 
the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of 50% in
principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, 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. 
 As set forth in, and subject to, the provisions of the Indenture, no Holder
of any Security of this series will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default
with respect to this series, the Holders of not less than 25% in principal amount of the Outstanding Securities of this series shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee,
and the Trustee shall not have received from the Holders of a majority in principal amount of the Outstanding Securities of this series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of and any premium or interest on this Security on or after the respective due dates expressed herein.

 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(s) and rate, and in the coin or currency, herein prescribed. 
 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 where the principal of and any premium and interest on this Security are payable or, subject to any laws or regulations applicable
thereto and to the right of the Company (limited as provided in the Indenture) to rescind the designation of any such transfer agent, at the main offices of the Company in Pittsburgh, Pennsylvania and in or at such other offices or agencies as the
Company may designate, 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. 
 Holders of the Securities of this series shall have the rights set forth in, and shall be deemed to be bound by the provisions of, the Registration
Rights Agreement dated as of February 23, 2007 (the “Registration Rights Agreement”) between the Company and Barclays Capital Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. Incorporated, as dealer managers,
subject to the terms and conditions set forth in the Registration Rights Agreement; provided, however, that the obligations of the Company under the Registration Rights Agreement, and the rights of the holders of the Securities of this series under
the Registration Rights Agreement, shall cease when and as provided in the Registration Rights Agreement without further notation on this Security, all pursuant to and in accordance with the terms of the Registration Rights Agreement.

 The Securities of this series are issuable only in registered form, without coupons, in denominations of
$100,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this
series 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 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 is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 As used in this Security, “Business Day” means any day other than a Saturday or Sunday, that is not a day on which banking institutions are
authorized or obligated by law or executive order to close in Pittsburgh, Pennsylvania or The City of New York. All other terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

 Alcoa Inc., a corporation duly organized and existing under the laws of Pennsylvania (herein
called the “Company”, which term includes any successor Person under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of Two

Payment Date”) to which interest has been paid or duly provided for, semi-annually in arrears on February 23 and August 23 in each year, commencing August 23, 2007, at the rate of 5.72% per annum, until the principal hereof
is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor

agencies as the Company may designate, by United States dollar check drawn on, or transfer to a United States dollar account maintained by the payee with, a bank in The City of New York; provided, however, that at the option of the Company payment
of interest may be made by United States dollar check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. 
 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 this place.

 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 September 30, 1993 (herein, as supplemented by the First Supplemental Indenture dated January 25, 2007 between the Company and the
Trustee (as defined below), called the “Indenture”), between the Company and The Bank of New York Trust Company, N.A., as successor to J. P. Morgan Trust Company, National Association (formerly Chase Manhattan Trust Company, National
Association), as successor trustee to PNC Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto
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. This Security is one of the series designated on the face hereof, initially issued in the aggregate principal amount of (U.S.) $750,000,000. 
 The Securities of this series are subject to redemption, as a whole or in part, at the option of the Company, at any time or from time to time, on at least 30 days, but not more than 60 days, prior notice to the
Holders of the Securities of this series given as described below, at a redemption price equal to the greater of: 
  

	 	•	 	 100% of the principal amount to be redeemed, plus accrued interest, if any, to the redemption date; or 


  

	 	•	 	 the sum of the present values of the Remaining Scheduled Payments, as defined below, discounted, on a semiannual basis, assuming a 360-day year consisting of twelve
30-day months, at the Treasury Rate, as defined below, plus 15 basis points, plus accrued interest to the date of redemption which has not been paid. 


 “Treasury Rate” means, with respect to any redemption date: 
  

	 	•	 	 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; provided that if no maturity is within three months before or after the maturity date for this Security, yields for
the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight line basis rounding to the nearest month; or



  

	 	•	 	 if that 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 semiannual 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 that
redemption date. 


 The Treasury Rate will be calculated on the third business day preceding the redemption date. 
  

 4 








 “Comparable Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining term of this Security to be redeemed 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 this Security. 
 “Independent Investment Banker” means
one of the Reference Treasury Dealers, to be appointed by the Company. 
 “Comparable Treasury Price” means, with respect to any
redemption date for this Security: 
  

	 	•	 	 the average of four Reference Treasury Dealer Quotations for the redemption date, after excluding the highest and lowest of such Reference Treasury Dealer
Quotations; or 


  

	 	•	 	 if the Trustee obtains fewer than four Reference Treasury Dealer Quotations, the average of all quotations obtained by the Trustee. 


 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as
determined by the Trustee, 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 such Reference Treasury Dealer at 3:30 p.m., New York City
time, on the third business day preceding such redemption date. 
 “Reference Treasury Dealer” means each of Citigroup Global
Markets Inc, Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and J.P. Morgan Securities Inc., and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities
dealer, which we refer to as a “Primary Treasury Dealer,” the Company will substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer. 
 “Remaining Scheduled Payments” means, with respect to each Security to be redeemed, the remaining scheduled payments of the principal thereof
and interest thereon that would be due after the related redemption date but for such redemption; provided, however, that, if such redemption date is not an interest payment date with respect to such Security, the amount of the next succeeding
scheduled interest payment thereon will be deemed to be reduced by the amount of interest accrued thereon to such redemption date. 
 In the
event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 Notice of redemption will be given by mail to Holders of Securities of this series, not less than 30 nor more than 60 days prior to the date fixed for
redemption, all as provided in the Indenture. 
 If a Change of Control Repurchase Event occurs and this Security has not been previously
redeemed, the Company will make an offer to each Holder of Securities of this series to repurchase all or any part (in integral multiples of $1,000) of that Holder’s Securities of this series at a 

  

 5 








 
repurchase price in cash equal to 101% of the aggregate principal amount of Securities of this series repurchased plus any accrued and unpaid interest on the
Securities of this series repurchased to, but not including, the date of repurchase. Within 30 days following any Change of Control Repurchase Event or, at the option of the Company, 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
Securities of this series on the payment date specified in the notice, 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. To the extent that the provisions of any securities laws or regulations
conflict with the Change of Control Repurchase event provisions of this Security, the Company may comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control
Repurchase Event provisions of this Security by virtue of such conflict. 
 On the repurchase date following a Change of Control Repurchase
Event, the Company will, to the extent lawful: 
  

	 	(1)	accept for payment all Securities of this series or portions of Securities of this series properly tendered pursuant to its offer; 

  

	 	(2)	deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Securities of this series or portions of Securities of this series properly tendered;
and 

  

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

 The Paying Agent will promptly mail to each Holder of
Securities of this series properly tendered the purchase price for the Securities of this series, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Security of this series equal in
principal amount to any unpurchased portion of any Securities of this series surrendered; provided that each new Security of this series will be in a principal amount of $100,000 and integral multiples of $1,000 in excess thereof. 
 The Company will not be required to make an offer to repurchase the Securities of this series 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 Securities of this series properly tendered and not withdrawn under such offer.

 “Below Investment Grade Ratings Event” means that on any day within the 60-day period (which period shall be extended so long as
the rating of the Securities of this Series is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) after the earlier of (1) the occurrence of a Change of Control; or (2) public notice of the
occurrence of a Change of Control or the intention by the Company to effect a Change of Control, the Securities of this series are rated below Investment Grade by each of the Rating Agencies. Notwithstanding the foregoing, a Below Investment Grade
Ratings Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a 

  

 6 








 
Below Investment Grade Ratings Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the
reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of
or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Ratings Event). 
 “Change of Control” means the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which
is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act), other than the Company, its subsidiaries, or its or such subsidiaries’ employee benefit plans, becomes the beneficial owner (as defined in Rules
13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the Company's Voting Stock or other Voting Stock into which the Company's Voting Stock is reclassified, consolidated, exchanged or
changed measured by voting power rather than number of shares. 
 “Change of Control Repurchase Event” means the occurrence of both
a Change of Control and a Below Investment Grade Ratings Event. 
 “Fitch” means Fitch Ratings Ltd. 
 “Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s);
a rating of BBB- or better by S&P or Fitch (or its equivalent under any successor rating categories of S&P and Fitch); and the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by the
Company. 
 “Moody’s” means Moody’s Investors Service Inc. 
 “Rating Agency” means (1) each of Moody’s, S&P and Fitch; and (2) if any of Moody’s, S&P or Fitch ceases to rate
the Securities of this series or fails to make a rating of the Securities of this series publicly available for reasons outside of the control of the Company, a “nationally recognized statistical rating organization” within the meaning of
Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, selected by the Company (as certified by a resolution of the Board of Directors) as a replacement agency for Moody’s, S&P or Fitch, or all of them, as the case may be. 
 “S&P” means Standard & Poor’s Ratings Services, a division of McGraw-Hill, Inc. 
 “Voting Stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date means the
capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person. 
 If
an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The provisions relating to defeasance and discharge set forth in Section 1302 of the Indenture and covenant defeasance set forth in
Section 1303 of the Indenture are applicable to the Securities of this series. 
 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 

  

 7 








 
the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of 50% in
principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, 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. 
 As set forth in, and subject to, the provisions of the Indenture, no Holder
of any Security of this series will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default
with respect to this series, the Holders of not less than 25% in principal amount of the Outstanding Securities of this series shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee,
and the Trustee shall not have received from the Holders of a majority in principal amount of the Outstanding Securities of this series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of and any premium or interest on this Security on or after the respective due dates expressed herein.

 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(s) and rate, and in the coin or currency, herein prescribed. 
 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 where the principal of and any premium and interest on this Security are payable or, subject to any laws or regulations applicable
thereto and to the right of the Company (limited as provided in the Indenture) to rescind the designation of any such transfer agent, at the main offices of the Company in Pittsburgh, Pennsylvania and in or at such other offices or agencies as the
Company may designate, 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. 
 Holders of the Securities of this series shall have the rights set forth in, and shall be deemed to be bound by the provisions of, the Registration
Rights Agreement dated as of February 23, 2007 (the “Registration Rights Agreement”) between the Company and Barclays Capital Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. Incorporated, as dealer managers,
subject to the terms and conditions set forth in the Registration Rights Agreement; provided, however, that the obligations of the Company under the Registration Rights Agreement, and the rights of the holders of the Securities of this series under
the Registration Rights Agreement, shall cease when and as provided in the Registration Rights Agreement without further notation on this Security, all pursuant to and in accordance with the terms of the Registration Rights Agreement. 
  

 8 








 The Securities of this series are issuable only in registered form, without coupons, in denominations of
$100,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this
series 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 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 is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 As used in this Security, “Business Day” means any day other than a Saturday or Sunday, that is not a day on which banking institutions are
authorized or obligated by law or executive order to close in Pittsburgh, Pennsylvania or The City of New York. All other terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

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
exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. 
 Payment of the principal of and any premium and interest on this Security will be made (a) at the Corporate Trust Office of the Trustee or such other office or agency of the Company as may be designated by it for

regulations applicable thereto and to the right of the Company (limited as provided in the Indenture) to rescind the designation of any such Paying Agent, at the main offices of the Company in Pittsburgh, Pennsylvania, or at such other offices or
agencies as the Company may designate, by United States dollar check drawn on, or transfer to a United States dollar account maintained by the payee with, a bank in The City of New York; provided, however, that at the option of the Company payment
of interest may be made by United States dollar check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. 
 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 this place.

 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 September 30, 1993 (herein, as supplemented by the First Supplemental Indenture dated January 25, 2007 between the Company and the
Trustee (as defined below), called the “Indenture”), between the Company and The Bank of New York Trust Company, N.A., as successor to J. P. Morgan Trust Company, National Association (formerly Chase Manhattan Trust Company, National
Association), as successor trustee to PNC Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto
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. This Security is one of the series designated on the face hereof, initially issued in the aggregate principal amount of (U.S.) $750,000,000. 
 The Securities of this series are subject to redemption, as a whole or in part, at the option of the Company, at any time or from time to time, on at least 30 days, but not more than 60 days, prior notice to the
Holders of the Securities of this series given as described below, at a redemption price equal to the greater of: 
  

	 	•	 	 100% of the principal amount to be redeemed, plus accrued interest, if any, to the redemption date; or 


  

	 	•	 	 the sum of the present values of the Remaining Scheduled Payments, as defined below, discounted, on a semiannual basis, assuming a 360-day year consisting of twelve
30-day months, at the Treasury Rate, as defined below, plus 15 basis points, plus accrued interest to the date of redemption which has not been paid. 


 “Treasury Rate” means, with respect to any redemption date: 
  

	 	•	 	 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; provided that if no maturity is within three months before or after the maturity date for this Security, yields for
the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight line basis rounding to the nearest month; or



  

	 	•	 	 if that 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 semiannual 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 that
redemption date. 


 The Treasury Rate will be calculated on the third business day preceding the redemption date. 
  

 4 








 “Comparable Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining term of this Security to be redeemed 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 this Security. 
 “Independent Investment Banker” means
one of the Reference Treasury Dealers, to be appointed by the Company. 
 “Comparable Treasury Price” means, with respect to any
redemption date for this Security: 
  

	 	•	 	 the average of four Reference Treasury Dealer Quotations for the redemption date, after excluding the highest and lowest of such Reference Treasury Dealer
Quotations; or 


  

	 	•	 	 if the Trustee obtains fewer than four Reference Treasury Dealer Quotations, the average of all quotations obtained by the Trustee. 


 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as
determined by the Trustee, 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 such Reference Treasury Dealer at 3:30 p.m., New York City
time, on the third business day preceding such redemption date. 
 “Reference Treasury Dealer” means each of Citigroup Global
Markets Inc, Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and J.P. Morgan Securities Inc., and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities
dealer, which we refer to as a “Primary Treasury Dealer,” the Company will substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer. 
 “Remaining Scheduled Payments” means, with respect to each Security to be redeemed, the remaining scheduled payments of the principal thereof
and interest thereon that would be due after the related redemption date but for such redemption; provided, however, that, if such redemption date is not an interest payment date with respect to such Security, the amount of the next succeeding
scheduled interest payment thereon will be deemed to be reduced by the amount of interest accrued thereon to such redemption date. 
 In the
event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 Notice of redemption will be given by mail to Holders of Securities of this series, not less than 30 nor more than 60 days prior to the date fixed for
redemption, all as provided in the Indenture. 
 If a Change of Control Repurchase Event occurs and this Security has not been previously
redeemed, the Company will make an offer to each Holder of Securities of this series to repurchase all or any part (in integral multiples of $1,000) of that Holder’s Securities of this series at a 

  

 5 








 
repurchase price in cash equal to 101% of the aggregate principal amount of Securities of this series repurchased plus any accrued and unpaid interest on the
Securities of this series repurchased to, but not including, the date of repurchase. Within 30 days following any Change of Control Repurchase Event or, at the option of the Company, 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
Securities of this series on the payment date specified in the notice, 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. To the extent that the provisions of any securities laws or regulations
conflict with the Change of Control Repurchase event provisions of this Security, the Company may comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control
Repurchase Event provisions of this Security by virtue of such conflict. 
 On the repurchase date following a Change of Control Repurchase
Event, the Company will, to the extent lawful: 
  

	 	(1)	accept for payment all Securities of this series or portions of Securities of this series properly tendered pursuant to its offer; 

  

	 	(2)	deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Securities of this series or portions of Securities of this series properly tendered;
and 

  

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

 The Paying Agent will promptly mail to each Holder of
Securities of this series properly tendered the purchase price for the Securities of this series, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Security of this series equal in
principal amount to any unpurchased portion of any Securities of this series surrendered; provided that each new Security of this series will be in a principal amount of $100,000 and integral multiples of $1,000 in excess thereof. 
 The Company will not be required to make an offer to repurchase the Securities of this series 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 Securities of this series properly tendered and not withdrawn under such offer.

 “Below Investment Grade Ratings Event” means that on any day within the 60-day period (which period shall be extended so long as
the rating of the Securities of this Series is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) after the earlier of (1) the occurrence of a Change of Control; or (2) public notice of the
occurrence of a Change of Control or the intention by the Company to effect a Change of Control, the Securities of this series are rated below Investment Grade by each of the Rating Agencies. Notwithstanding the foregoing, a Below Investment Grade
Ratings Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a 

  

 6 








 
Below Investment Grade Ratings Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the
reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of
or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Ratings Event). 
 “Change of Control” means the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which
is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act), other than the Company, its subsidiaries, or its or such subsidiaries’ employee benefit plans, becomes the beneficial owner (as defined in Rules
13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the Company's Voting Stock or other Voting Stock into which the Company's Voting Stock is reclassified, consolidated, exchanged or
changed measured by voting power rather than number of shares. 
 “Change of Control Repurchase Event” means the occurrence of both
a Change of Control and a Below Investment Grade Ratings Event. 
 “Fitch” means Fitch Ratings Ltd. 
 “Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s);
a rating of BBB- or better by S&P or Fitch (or its equivalent under any successor rating categories of S&P and Fitch); and the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by the
Company. 
 “Moody’s” means Moody’s Investors Service Inc. 
 “Rating Agency” means (1) each of Moody’s, S&P and Fitch; and (2) if any of Moody’s, S&P or Fitch ceases to rate
the Securities of this series or fails to make a rating of the Securities of this series publicly available for reasons outside of the control of the Company, a “nationally recognized statistical rating organization” within the meaning of
Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, selected by the Company (as certified by a resolution of the Board of Directors) as a replacement agency for Moody’s, S&P or Fitch, or all of them, as the case may be. 
 “S&P” means Standard & Poor’s Ratings Services, a division of McGraw-Hill, Inc. 
 “Voting Stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date means the
capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person. 
 If
an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The provisions relating to defeasance and discharge set forth in Section 1302 of the Indenture and covenant defeasance set forth in
Section 1303 of the Indenture are applicable to the Securities of this series. 
 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 

  

 7 








 
the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of 50% in
principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, 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. 
 As set forth in, and subject to, the provisions of the Indenture, no Holder
of any Security of this series will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default
with respect to this series, the Holders of not less than 25% in principal amount of the Outstanding Securities of this series shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee,
and the Trustee shall not have received from the Holders of a majority in principal amount of the Outstanding Securities of this series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of and any premium or interest on this Security on or after the respective due dates expressed herein.

 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(s) and rate, and in the coin or currency, herein prescribed. 
 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 where the principal of and any premium and interest on this Security are payable or, subject to any laws or regulations applicable
thereto and to the right of the Company (limited as provided in the Indenture) to rescind the designation of any such transfer agent, at the main offices of the Company in Pittsburgh, Pennsylvania and in or at such other offices or agencies as the
Company may designate, 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. 
 Holders of the Securities of this series shall have the rights set forth in, and shall be deemed to be bound by the provisions of, the Registration
Rights Agreement dated as of February 23, 2007 (the “Registration Rights Agreement”) between the Company and Barclays Capital Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. Incorporated, as dealer managers,
subject to the terms and conditions set forth in the Registration Rights Agreement; provided, however, that the obligations of the Company under the Registration Rights Agreement, and the rights of the holders of the Securities of this series under
the Registration Rights Agreement, shall cease when and as provided in the Registration Rights Agreement without further notation on this Security, all pursuant to and in accordance with the terms of the Registration Rights Agreement. 
  

 8 








 The Securities of this series are issuable only in registered form, without coupons, in denominations of
$100,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this
series 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 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 is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 As used in this Security, “Business Day” means any day other than a Saturday or Sunday, that is not a day on which banking institutions are
authorized or obligated by law or executive order to close in Pittsburgh, Pennsylvania or The City of New York. All other terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
