 [FORM OF REVERSE SIDE OF INITIAL SECURITY] 
 9 3/4% Senior Subordinated Note Due 2015 
  

	1.	Interest 

 Metal Services Merger Sub Corp., a
Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate
per annum shown above; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of $0.05 per week per $1,000 principal amount
of Initial Securities for the first 90-day period immediately following the occurrence of a Registration Default (increasing by an additional $0.05 per week per $1,000 principal amount of Initial Securities with respect to each subsequent 90-day
period until all Registration Defaults have been cured, up to a maximum additional interest rate of $0.30 per week per $1,000 principal amount of Initial Securities) from and including the date on which any such Registration Default shall occur to
but excluding the date on which all Registration Defaults have been cured. The Company will pay interest semiannually on February 1 and August 1 of each year, commencing August 1, 2007. Interest on the Securities will accrue from the
most recent date to which interest has been paid or, if no interest has been paid, from January 25, 2007. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue principal at
the rate borne by this Security plus 1.0% per annum, and it will pay interest on overdue installments of interest at the same rate to the extent lawful. 
  

	2.	Method of Payment 

 The Company will pay interest on
the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the January 15 or July 15 next preceding the interest payment date even if Securities are canceled after the
record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified
by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the
Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 
  

 8 

	3.	Paying Agent and Registrar 

 Initially, The Bank of
New York, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar. 
  

	4.	Indenture 

 The Company issued the Securities under
an Indenture dated as of January 25, 2007 (“Indenture”), among the Company, the Guarantor named therein and the Trustee. 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 (15 U.S.C. §§ 77aaa-77bbbb) (the “Act”) Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms. 
 The Securities
are general unsecured obligations of the Company. The Company shall be entitled, subject to its compliance with Section 4.03 of the Indenture, to issue Additional Securities pursuant to Section 2.14 of the Indenture. The Initial Securities
issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that
limit the ability of the Company and its Restricted Subsidiaries to incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments; engage in transactions with affiliates; create liens on
assets; transfer or sell assets; guarantee indebtedness; restrict dividends or other payments of Restricted Subsidiaries of the Company; and consolidate, merge or transfer all or substantially all of its assets and the assets of its subsidiaries.
These covenants are subject to important exceptions and qualifications. 
  

	5.	Optional Redemption 

 Except as set forth below, the
Company shall not be entitled to redeem the Securities. 
 On and after February 1, 2011, the Company shall be entitled at its option to
redeem all or a portion of the Securities upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed in percentages of principal amount on the redemption date), plus accrued interest to the redemption date (subject
to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on February 1 of the years set forth below: 
  

				
	 Period
	  	Redemption
Price	 
	 2011
	  	104.875	%
	 2012
	  	102.438	%
	 2013 and thereafter
	  	100.000	%

 Prior to February 1, 2010, the Company shall be entitled at its option on one or more occasions to
redeem Securities (which includes Additional Securities, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Securities (which includes Additional Securities, if any) originally issued at a redemption
price (expressed as a percentage of principal amount) of 109.75%, plus accrued and unpaid interest to the redemption date, with the net cash proceeds from one or more Public Equity Offerings; provided, however, that (1) at least
65% of such aggregate principal amount of Securities (which includes Additional Securities, if any) remains outstanding immediately after the occurrence of each such redemption (other than Securities held, directly or indirectly, by the Company or
its Affiliates); and (2) each such redemption occurs within 90 days after the date of the related Public Equity Offering. 
 Prior to
February 1, 2011, the Company shall be entitled at its option to redeem all, but not less than all, of the Securities at a redemption price equal to 100% of the principal amount of the Securities plus the Applicable Premium as of, and accrued
and unpaid interest to, the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date). The Company shall cause notice of such redemption to be mailed by first-class
mail to each Holder’s registered address, not less than 30 nor more than 60 days prior to the redemption date. 
  

	6.	Notice of Redemption 

 Notice of redemption will be
mailed at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed at his registered address. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in
whole multiples of $1,000. The Company shall redeem Securities of $2,000 principal amount or less in whole and not in part. If money sufficient to pay the redemption price of and accrued interest on all Securities (or portions thereof) to be
redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for
redemption. 
  

	7.	Put Provisions 

 Upon a Change of Control, any
Holder of Securities will have the right to cause the Company to repurchase all or any part of the Securities of such Holder at a repurchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued interest to the
date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the related interest payment date) as provided in, and subject to the terms of, the Indenture. 

	8.	Guaranty 

 The payment by the Company of the
principal of, and premium and interest on, the Securities is fully and unconditionally guaranteed on a joint and several senior subordinated basis by each of the Guarantors to the extent set forth in the Indenture. 
  

	9.	Subordination 

 The Securities are subordinated to
Senior Indebtedness of the Company and the Guarantors on the terms and subject to the conditions set forth in the Indenture. To the extent provided in the Indenture, Senior Indebtedness must be paid before the Securities may be paid. Each
Securityholder by accepting a Security agrees to the subordination provisions contained in the Indenture and authorizes the Trustee to give it effect and appoints the Trustee as attorney-in-fact for such purpose. 
  

	10.	Denominations; Transfer; Exchange 

 The Securities
are in registered form without coupons in denominations of $1,000 principal amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things,
to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the
case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date. 
  

	11.	Persons Deemed Owners 

 The registered Holder of
this Security may be treated as the owner of it for all purposes. 
  

	12.	Unclaimed Money 

 If money for the payment of
principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the
money must look only to the Company and not to the Trustee for payment. 
  

	13.	Discharge and Defeasance 

 Subject to certain
conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the Indenture if the 

  

 11 

 
Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity,
as the case may be. 
  

	14.	Amendment, Waiver 

 Subject to certain exceptions
set forth in the Indenture, (a) the Indenture and the Securities may be amended with the written consent of the Holders of at least a majority in principal amount outstanding of the Securities and (b) any default or noncompliance with any
provision may be waived with the written consent of the Holders of a majority in principal amount outstanding of the Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company,
Guarantors and the Trustee shall be entitled to amend the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 of the Indenture, or to provide for uncertificated Securities in addition to
or in place of certificated Securities, or to add guarantees with respect to the Securities, including Guaranties, or to secure the Securities, or to add additional covenants or surrender rights and powers conferred on the Company or the Guarantors,
or to comply with any requirement of the SEC in connection with qualifying the Indenture under the Act, or to make any change that does not adversely affect the rights of any Securityholder, or to make amendments to provisions of the Indenture
relating to the form, authentication, transfer and legending of the Securities or to conform the text of the Indenture or the Securities to any provision set forth in the Offering Circular relating to the Securities, or to provide for the issuance
of Additional Securities in accordance with the limitations set forth in the Indenture as of the date of the Indenture. 
  

	15.	Defaults and Remedies 

 Under the Indenture, Events
of Default include (a) default for 30 days in payment of interest on the Securities; (b) default in payment of principal on the Securities at maturity, upon redemption pursuant to paragraph 5 of the Securities, upon acceleration or
otherwise, or failure by the Company to redeem or purchase Securities when required; (c) failure by the Company or any Guarantor to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse of
time; (d) certain accelerations (including failure to pay within any grace period after final maturity) of other Indebtedness of the Company, any Subsidiary or any Significant Subsidiary if the amount accelerated (or so unpaid) exceeds $15
million; (e) certain events of bankruptcy or insolvency with respect to the Company and the Significant Subsidiaries; (f) certain judgments or decrees for the payment of money in excess of $15 million; and (g) certain defaults with
respect to Guaranties. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. Certain events of bankruptcy
or insolvency are Events of Default which will result in the Securities being due and payable immediately upon the occurrence of such Events of Default. 
 Securiryholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the 

  

 12 

 
Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice
is in the interest of the Holders. 
  

	16.	Trustee Dealings with the Company 

 Subject to
certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its
Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  

	17.	No Recourse Against Others 

 A director, officer,
employee or stockholder, as such, of the Company, any Subsidiary Guarantor or the Trustee shall not have any liability for any obligations of the Company under the Securities or the Indenture or of such Subsidiary Guarantor under its Subsidiary
Guaranty or the Indenture for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities. 
  

	18.	Authentication 

 This Security shall not be valid
until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security. 
  

	19.	Abbreviations 

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

	20.	CUSIP Numbers 

 Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures the Company has caused CUSIP numbers to be printed on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to
Securityholders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

  

 13 

	21.	Holders’ Compliance with Registration Rights Agreement. 

 Each Holder of a Security, by acceptance hereof, acknowledges and agrees to the provisions of the Registration Rights Agreement, including the obligations of the Holders with respect to a registration and the
indemnification of the Company to the extent provided therein. 
  

	22.	Governing Law. 

 THIS SECURITY SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 The Company will furnish to any Securityholder upon written
request and without charge to the Security holder a copy of the Indenture which has in it the text of this Security in larger type. Requests may be made to:
