(BACK OF NOTE)


 


6.875% Senior Notes Due 2028


 


THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE
INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE
TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAYBE REQUIRED PURSUANT TO
SECTION 305 OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 305 OF THE INDENTURE,
(III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 310 OF THE INDENTURE AND (IV) THIS
GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.


 


Capitalized terms used herein shall have the
meanings assigned to them in the Indenture referred to below unless otherwise indicated. The securities represented by this Note
and any additional Securities of the same series issued under the Indenture are collectively referred to herein as “the Notes.”


 


1.                 
Interest. American Axle & Manufacturing, Inc., a Delaware corporation (the “Company”), promises to
pay interest on the principal amount of this Note at 6.875% per annum from the date hereof until maturity. The Company shall pay
interest in arrears semiannually on January 1 and July 1 of each year, or if any such day is not a Business Day, on the
next succeeding Business Day (each an “Interest Payment Date”). Interest on the Notes shall accrue from the most recent
date to which interest has been paid or duly provided for or, if no interest has been paid, from the date of issuance through but
excluding the date on which interest is paid. The first Interest Payment Date shall be January 1, 2021. Interest shall be computed
on the basis of a 360-day year of twelve 30-day months.


 


2.                 
Method of Payment. The Company shall pay interest on the Notes (except defaulted interest) to the Persons who are
registered Holders of Notes at the close of business on December 15 or June 15, as applicable, immediately preceding
the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date,
except as provided in Section 307 of the Indenture with respect to defaulted interest. The Notes shall be payable as to principal,
premium, if any, and interest at the office or agency of the Company maintained for such purpose in the borough of Manhattan, The
City of New York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses
set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds shall be required
with respect to principal of and interest, premium on, all Global Notes and all other Notes the Holders of which shall have provided
wire transfer instructions to the Company or the Paying Agent. Such payment shall be in such coin or currency of the United States
of America as at the time of payment is legal tender for payment of public and private debts.


 









     


     


    

 


3.                 
 Paying Agent and Registrar. Initially, U.S. Bank National Association, the Trustee under the Indenture, shall act
as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or
any of its Subsidiaries may act in any such capacity.


 


4.                 
Indenture. The Company issued the Notes under an Indenture, dated as of November 3, 2011, among the Company, certain
guarantors and U.S. Bank National Association, as trustee (the “Trustee”) as supplemented by the First Supplemental
Indenture, dated March 23, 2017, among Holdings, the Company, Alpha SPV I, Inc., certain subsidiary guarantors and the Trustee,
the Second Supplemental Indenture, dated May 17, 2017, among Holdings, the Company, certain subsidiary guarantors and the Trustee
and the Third Supplemental Indenture, dated March 23, 2018, among Holdings, the Company, certain subsidiary guarantors and the
Trustee (collectively, the “Indenture”). 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 of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The
Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. This
Note is an obligation of the Company, which series is initially limited to $400,000,000 in aggregate principal amount. The Indenture
pursuant to which this Note is issued provides that an unlimited amount of additional Notes may be issued thereunder.


 


5.                 
Optional Redemption. On and after July 1, 2023, the Company will be entitled at its option to redeem all or
a portion of the Notes upon not less than 10 nor more than 60 days’ notice, at the Redemption Prices (expressed in percentages
of principal amount on the Redemption Date), plus accrued and unpaid interest to the Redemption Date (subject to the right of Holders
on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date), if redeemed during the 12-month
period commencing on July 1 of the years set forth below:


 


	Period	 Redemption Price 
	2023	103.438%
	2024	101.719%
	2025 and thereafter	100.000%





 


Prior to July 1, 2023, the Company will
be entitled at its option to redeem all or a portion of the Notes at a Redemption Price equal to 100% of the principal amount of
the Notes plus the Applicable Premium plus accrued and unpaid interest to the Redemption Date (subject to the right of Holders
on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date). Notice of such redemption must
be mailed by first-class mail to each Holder’s registered address or delivered electronically, not less than 10 nor more
than 60 days prior to the Redemption Date.


 


In addition, the Company may on any one or
more occasions prior to July 1, 2023 redeem up to 35% of the original principal amount of the Notes (calculated after giving
effect to any issuance of additional Notes) with the Net Cash Proceeds of one or more Equity Offerings at a Redemption Price of
106.875% of the principal amount thereof plus accrued and unpaid interest, if any, to the applicable Redemption Date (subject to
the right of Holders on the relevant


 






     


     


    

 





Regular Record Date to receive interest due on the relevant
Interest Payment Date); provided that:


 


(1) at least 65% of the original principal
amount of the Notes (calculated after giving effect to any issuance of additional Notes) remains outstanding after each such redemption;
and


 


(2) the redemption occurs within 90 days after
the closing of such Equity Offering.


 


“Applicable Premium” means, with
respect to a Note on any Redemption Date, the greater of (a) 1.0% of the principal amount of such Note, and (b) the excess, if
any, of (a) the present value as of such Redemption Date of (i) the Redemption Price of such Note on July 1, 2023 (as set
forth above), plus (ii) all required interest payments due on such Note through July 1, 2023 (excluding accrued but unpaid
interest to the Redemption Date), computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 50 basis
points, over (b) the then outstanding principal of such Note.


 


“Equity Offering” means a public
offering for cash by the Company or Holdings of its Common Stock, or options, warrants or rights with respect to its Common Stock,
other than (x) public offerings with respect to the Company’s or Holdings’ Common Stock, or options, warrants or rights,
registered on Form S-4 or S-8, (y) an issuance to any Subsidiary of Holdings or (z) any offering of Common Stock issued in connection
with a transaction that constitutes a Change of Control.


 


“Net Cash Proceeds” means, with
respect to any issuance or sale of Capital Stock of the Company or Holdings, as applicable, the cash proceeds of such issuance
or sale net of attorneys’ fees, accountants’ fees, underwriters’ or placement agents’ fees, listing fees,
discounts or commissions and brokerage, consultant and other fees and charges actually incurred in connection with such issuance
or sale and net of taxes paid or payable as a result of such issuance or sale (after taking into account any available tax credit
or deductions and any tax sharing arrangements).


 


“Treasury Rate” means the yield
to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published
in the most recent Federal Reserve Statistical Release H.15 that has become publicly available at least two Business Days prior
to the Redemption Date (or, if such Statistical Release is no longer published, any publicly available source or similar market
data)) most nearly equal to the period from the Redemption Date to July 1, 2023; provided, however, that if the period
from the Redemption Date to July 1, 2023 is not equal to the constant maturity of a United States Treasury security for which
a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth
of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if
the period from the Redemption Date to July 1, 2023 is less than one year, the weekly average yield on actually traded United
States Treasury securities adjusted to a constant maturity of one year will be used.


 









     


     


    

 


Holders of the Notes to be redeemed will receive
notice of such redemption at least 10 days, but not more than 60 days, before the Redemption Date. At the Company’s option,
a notice of redemption may be conditioned on the satisfaction of one or more conditions. If so conditioned, such a notice of redemption
shall state that, in the Company’s discretion, the Redemption Date may be delayed until such time as any or all of such conditions
shall be satisfied (or waived by the Company in its discretion), or such redemption may not occur and such notice may be rescinded
in the event that any or all of such conditions have not been satisfied (or waived by the Company in its discretion) by the Redemption
Date, or the Redemption Date so delayed. Once a notice of redemption is delivered (or, in the event of a notice of conditional
redemption, once the conditions set forth therein are satisfied), the Notes to be redeemed will become due and payable on the Redemption
Date, or the Redemption Date so delayed, at the Redemption Price, plus accrued and unpaid interest to the Redemption Date, or the
Redemption Date so delayed. If less than all the Notes are to be redeemed at any time, the Trustee will select Notes to be redeemed
on a pro rata basis or by any other method the Trustee deems fair and appropriate. Unless the Company defaults in payment
of the Redemption Price, on and after the Redemption Date or the Redemption Date so delayed, interest will cease to accrue on the
Notes or portions thereof called for redemption.


 


6.                 
Change of Control. Upon the occurrence of a Change of Control, the Company will make an offer (a “Change of
Control Offer”) to each Holder to repurchase all or any part of each Holder’s Notes at a purchase price (the “Change
of Control Purchase Price”) equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the
repurchase date. Within 30 days following any Change of Control, the Company will (i) cause a notice of the Change of Control Offer
to be sent at least once to the Dow Jones News Service or similar business news service in the United States; and (ii) send, by
first-class mail or deliver electronically, with a copy to the Trustee, a notice to each registered Holder stating: (1) that a
Change of Control has occurred and a Change of Control Offer is being made pursuant to the Indenture and that all Notes timely
tendered will be accepted for payment; (2) the Change of Control Purchase Price and the repurchase date, which shall be, subject
to any contrary requirements of applicable law, a Business Day no earlier than 10 days nor later than 60 days from the date such
notice is mailed (the “Change of Control Payment Date”); (3) the circumstances and relevant facts regarding the Change
of Control (including information with respect to pro forma historical income, cash flow and capitalization after giving effect
to the Change of Control); and (4) the procedures that Holders of Notes must follow in order to tender their Notes (or portions
thereof) for payment, and the procedures that Holders of Notes must follow in order to withdraw an election to tender Notes (or
portions thereof) for payment.


 


The Company shall comply with the requirements
of Rule 14e of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws
or regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes in
connection with a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with
the terms of the Notes or the Indenture, the Company will comply with the applicable securities laws and regulations and will not
be deemed to have breached its obligations under the Notes or the Indenture by virtue of such compliance.


 









     


     


    

 


On the Change of Control Payment Date, the
Company will, to the extent lawful, (1) accept for payment all Notes or portions thereof properly tendered pursuant to the Change
of Control Offer, (2) deposit with the Paying Agent an amount equal to the Change of Control Purchase Price in respect of all Notes
or portions thereof properly tendered and (3) 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 or portions thereof being purchased by the
Company. The Paying Agent will promptly mail to each registered Holder of Notes properly tendered the Change of Control Purchase
Price for such 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 the Notes surrendered by such Holder, if any; provided,
that each such new Note will be in a principal amount of $1,000 or an integral multiple thereof. The Company will publicly announce
the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.


 


The Company will not be required to make a
Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times
and otherwise in compliance with the requirements set forth herein and all other provisions of the Indenture and terms of the Notes
applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such
Change of Control Offer.


 


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


 


(a) any “person” or “group”
of related persons (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) becomes the beneficial owner (as defined
in Rules 13d-3 and 13d-5 under the Exchange Act, except that such person or group shall be deemed to have “beneficial ownership”
of all shares that any such person or group has the right to acquire, whether such right is exercisable immediately or only after
the passage of time), directly or indirectly, of 50% of the total voting power of the voting stock of Holdings or the Company (or
their successors by merger, consolidation or purchase of all or substantially all of their assets);


 


(b) the sale, assignment, 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 Holdings and its Subsidiaries, taken as a whole, or of the Company and its Subsidiaries,
taken as a whole, to any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act);


 


(c) the adoption by the stockholders of Holdings
or the Company of a plan or proposal for the liquidation or dissolution of Holdings or the Company; or


 


(d) Holdings ceases to own, directly or indirectly,
all of the Capital Stock of the Company (other than in connection with a merger of Holdings into the Company permitted by the Indenture).


 


7.                 
Consolidation, Merger, Sale or Conveyance.


 


(a) Neither the Company nor Holdings may consolidate
with or merge into any other Person or convey, transfer or lease their properties and assets substantially as an entirety to any
Person, unless:


 









     


     


    

 


(1) the successor or transferee
entity, if other than the Company or Holdings, as the case may be, is a corporation organized and existing under the laws of the
United States, any state thereof or the District of Columbia and expressly assumes by a supplemental indenture executed and delivered
to the Trustee, in form reasonably satisfactory to the Trustee, the due and punctual payment of the principal of, any premium on
and any interest on, all the outstanding notes and the performance of every covenant and obligation in the Indenture to be performed
or observed by the Company or Holdings, as the case may be;


 


(2) immediately after giving
effect to the transaction, no Event of Default and no event which, after notice or lapse of time or both, would become an Event
of Default, has happened and is continuing; and


 


(3) the Company or Holdings,
as the case may be, has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each in the form required
by the Indenture and stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is
required in connection with such transaction, such supplemental indenture comply with the foregoing provisions relating to such
transaction.


 


(b) No Subsidiary Guarantor may consolidate
with or merge into any other Person or convey, transfer or lease their properties and assets substantially as an entirety to any
Person, unless:


 


(1) the successor or transferee
Person, if not a Subsidiary Guarantor prior to such merger, conveyance, transfer or lease, shall be a Person organized and existing
under the laws of the jurisdiction under which such Subsidiary was organized or under the laws of the United States of America,
or any State thereof or the District of Columbia, and expressly assumes, by a supplemental indenture, all the obligations of such
Subsidiary under its Guarantee; provided, however, that the foregoing shall not apply in the case of a Subsidiary
Guarantor (x) that has been, or will be as a result of the subject transaction, disposed of in its entirety to another Person (other
than to the Company, Holdings or an Affiliate of the Company or Holdings), whether through a merger, consolidation or sale of Capital
Stock or assets or (y) that, as a result of the disposition of all or a portion of its Capital Stock, ceases to be a Subsidiary;


 


(2) immediately after giving
effect to the transaction, no Event of Default and no event which, after notice or lapse of time or both, would become an Event
of Default, has happened and is continuing; and


 


(3) the Company has delivered
to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance,
transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture
comply with this paragraph 7 and that all conditions precedent herein provided for relating to such transaction have been complied
with.


 









     


     


    

 


(c) Upon any consolidation by the Company,
Holdings or any Subsidiary Guarantor with or merger by the Company, Holdings or any Subsidiary Guarantor, as the case may be, with
or into any other corporation or any conveyance, transfer or lease of the properties and assets of the Company, Holdings or any
Subsidiary Guarantor, as the case may be, substantially as an entirety to any Person, the successor Person formed by such consolidation
or into which the Company, Holdings or such Subsidiary Guarantor is merged or to which such conveyance, transfer or lease is made
shall succeed to, and be substituted for, and may exercise every right and power of, and be subject to every obligation of, the
Company, Holdings or such Subsidiary Guarantor, as the case may be, under the Indenture and the Notes or the Guarantees, as the
case may be, with the same effect as if such successor Person had been named as the Company, Holdings or such Subsidiary Guarantor,
as the case may be, therein, and in the event of any such conveyance or transfer, the Company, Holdings or any Subsidiary Guarantor,
as the case may be, except in the case of a lease, shall be discharged of all obligations and covenants under the Indenture and
the Notes or the Guarantees, as the case may be, and may be dissolved and liquidated.


 


8.                 
Limitation on Liens. The Company and Holdings will not, and will not permit any Restricted Subsidiary to, create,
incur, issue, assume or guarantee any indebtedness for money borrowed (“Debt”) secured by a Mortgage upon any Operating
Property, or upon shares of Capital Stock or Debt issued by any Restricted Subsidiary and owned by the Company or Holdings or any
Restricted Subsidiary, whether owned at the original date of the Indenture (November 3, 2011) or thereafter acquired, without effectively
providing concurrently that the notes of each series then outstanding under the Indenture are secured equally and ratably with
or, at the Company’s option, prior to such Debt so long as such Debt shall be so secured.


 


The foregoing restriction shall not apply
to, and there shall be excluded from Debt in any computation under such restriction, Debt secured by:


 


(1) Mortgages on any property
existing at the time of the acquisition thereof;


 


(2) Mortgages on property of
a corporation existing at the time such corporation is merged into or consolidated with the Company or Holdings or a Restricted
Subsidiary or at the time of a sale, lease or other disposition of the properties of such corporation (or a division thereof) as
an entirety or substantially as an entirety to the Company, Holdings or a Restricted Subsidiary; provided that any such
Mortgage does not extend to any property owned by the Company, Holdings or any Restricted Subsidiary immediately prior to such
merger, consolidation, sale, lease or disposition;


 


(3) Mortgages on property of
a corporation existing at the time such corporation becomes a Restricted Subsidiary;


 


(4) Mortgages in favor of the
Company, Holdings or a Restricted Subsidiary;


 


(5) Mortgages to secure all
or part of the cost of acquisition, construction, development or improvement of the underlying property, or to secure debt


 









     


     


    

 


incurred to provide funds for any such purpose;
provided that the commitment of the creditor to extend the credit secured by any such Mortgage shall have been obtained
no later than 360 days after the later of (a) the completion of the acquisition, construction, development or improvement of such
property or (b) the placing in operation of such property;


 


(6) Mortgages in favor of the
United States of America or any State thereof, or any department, agency or instrumentality or political subdivision thereof, to
secure partial, progress, advance or other payments; and


 


(7) Mortgages existing on the
original date of the Indenture (November 3, 2011) or any extension, renewal, replacement or refunding of any Debt secured by a
Mortgage existing on the original date of the Indenture (November 3, 2011) or referred to in clauses (1) to (3) or (5); provided
that any such extension, renewal, replacement or refunding of such Debt shall be created within 360 days of repaying the Debt
secured by the Mortgage referred to in clauses (1) to (3) or (5) and the principal amount of the Debt secured thereby and not otherwise
authorized by clauses (1) to (3) or (5) shall not exceed the principal amount of Debt, plus any premium or fee payable in connection
with any such extension, renewal, replacement or refunding, so secured at the time of such extension, renewal, replacement or refunding;
provided further that this clause (7) shall not include Mortgages securing Debt incurred under the Credit Agreement or any

secured by Mortgages permitted as described in clauses (1) through (7) of the immediately preceding paragraph) plus all Attributable
Debt of the Company, Holdings and the Restricted Subsidiaries in respect of Sale and Leaseback Transactions with respect to Operating

Transaction as would be permitted as described in clauses (1) through (4) of this section), plus the aggregate principal amount
of Debt secured by Mortgages on Operating Properties then outstanding (not including any such Debt secured by Mortgages described
in clauses (1) through (7) of paragraph 8 above) which do not equally and ratably secure such outstanding notes (or secure such
outstanding notes on a basis that is prior to other Debt secured thereby), would not exceed 10% of Consolidated Net Tangible Assets.


 


10.

obligations set forth in Article Seventeen of the Indenture. Any such supplemental indenture will be executed and delivered no

guarantees such Guarantee Indebtedness. The Guarantee of the Notes by any Subsidiary Guarantor will be released and discharged
in accordance with Article Seventeen of the Indenture.


 


The obligations of each Subsidiary Guarantor
will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary
Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of
the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under the Indenture, result
in the obligations of such Subsidiary Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer
under federal or state law.


 


Following the first day (the “Suspension
Date”):


 


(1) the Notes have an Investment
Grade Rating from both of the Ratings Agencies; and


 


(2) no Default has occurred
and is continuing under the Indenture;


 


Holdings, the Company and their Subsidiaries will not be subject
to the provisions of this covenant.


 


In addition, upon the occurrence of a Suspension
Date, the Company may elect, by delivering written notice thereof to the Trustee, to suspend the Guarantees of the Subsidiary Guarantors.
If at any time the Notes’ credit rating is downgraded from an Investment Grade Rating by any Ratings Agency or if a Default
or Event of Default occurs and is continuing, then (i) this covenant will thereafter be reinstated (the “Reinstatement Date”),
unless and until the Notes subsequently attain an Investment Grade Rating and no Default or Event of Default is in existence (in
which event this covenant shall no longer be in effect for such time that the Notes maintain an Investment Grade Rating and no
Default or Event of Default is in existence) and (ii) the Guarantees of the Subsidiary Guarantors previously suspended will be
automatically reinstated.


 


“Guarantee Indebtedness” means,
with respect to any Person on any date of determination (without duplication):


 


(1) the principal of and premium
(if any) in respect of indebtedness of such Person for borrowed money;


 


(2) the principal of and premium

within 30 days of incurrence) other than obligations with respect to letters of credit securing obligations (other


 









     


     


    

 


than obligations described in clauses (1) and (2)
above) entered into in the ordinary course of business of such Person to the extent such letters of credit are not drawn upon or,
to the extent drawn upon, such drawing is reimbursed no later than the fifth business day following receipt by such Person of a
demand for reimbursement following payment on the letter of credit;


 


(4) the principal component
or liquidation preference of all obligations of any Subsidiary that is not a Subsidiary Guarantor with respect to the redemption,
repayment or other repurchase of any Preferred Stock (but excluding, in each case, any accrued dividends);


 


(5) the principal component
of all Guarantee Indebtedness of other Persons secured by a lien on any asset of such Person, whether or not such Guarantee Indebtedness
is assumed by such Person; provided, however, that the amount of such Guarantee Indebtedness will be the lesser of
(a) the fair market value of such asset at such date of determination and (b) the amount of such Guarantee Indebtedness of such
other Persons; and


 


(6) the principal component
of Guarantee Indebtedness of other Persons to the extent guaranteed by such Person (whether or not such items would appear on the
balance sheet of the guarantor or obligor).

Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.


 


15.             
Amendment, Supplement and Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment

Notes to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority
in principal amount of the Notes then outstanding. The Indenture also contains provisions permitting the Holders of specified percentages
in principal amount of the Notes at the time outstanding, on behalf of the Holders of all outstanding Notes, 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 Note shall be conclusive and binding upon such Holder and upon all future Holders
of this Note and of any Note issued upon the registration of transfer hereof or in exchange or in lieu hereof, whether or not notation
of such consent or waiver is made upon this Note.


 


16.

on the Notes when such interest becomes due and payable, and continuance of such default for a period of 30 days;

default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee

such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder;


 









     


     


    

 


(d) the Guarantee of (i) Holdings or (ii)

audited consolidated financial statements for Holdings) would constitute a Significant Subsidiary, in each case, ceases to be in
full force and effect or is declared null and void or Holdings or any such Subsidiary Guarantor denies that it has any further
liability under its Guarantee to the Note Holders, or has given notice to such effect (other than by reason of the termination
of the Indenture or the release of such Guarantee in accordance with the Indenture), and such condition shall have continued for
a period of 30 days after notice is given as specified in the Indenture;


 


(e) default in the payment of principal when
due or resulting in acceleration of other Indebtedness of the Company, Holdings or any Significant Subsidiary for borrowed money
where the aggregate principal amount with respect to which the default or acceleration has occurred exceeds $100 million and such
acceleration has not been rescinded or annulled or such Indebtedness repaid within a period of 30 days after written notice to
the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Notes then
outstanding; provided that if any such default is cured, waived, rescinded or annulled, then the Event of Default by reason
thereof would be deemed not to have occurred;


 


(f) failure by Holdings, the Company or any
Significant Subsidiary to pay final and nonappealable judgments aggregating in excess of $100 million (net of any amounts that
are covered by insurance issued by a reputable and creditworthy insurance company), which judgments are not paid, discharged or
stayed for a period of 30 days after such judgment becomes final;


 


(g) the entry by a court having jurisdiction
in the premises of (A) a decree or order for relief in respect of the Company, Holdings or any Significant Subsidiary in an involuntary
case or proceeding under Bankruptcy Law or (B) a decree or order adjudging the Company, Holdings or any Significant Subsidiary
a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition
of or in respect of the Company, Holdings or such Significant Subsidiary under any applicable Federal or State law, or appointing
a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company, Holdings or such Significant
Subsidiary or of any substantial part of their property, or ordering the winding up or liquidation of their affairs, and the continuance
of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive
days;


 


(h) the commencement by the Company, Holdings
or any Significant Subsidiary of a voluntary case or proceeding under Bankruptcy Law or of any other case or proceeding to be adjudicated
a bankrupt or insolvent, or the consent by them to the entry of a decree or order for relief in respect of the Company, Holdings
or any Significant Subsidiary in an involuntary case or proceeding under Bankruptcy Law or to the commencement of any bankruptcy
or insolvency case or proceeding against them, or the filing by them of a petition or answer or consent seeking reorganization
or relief under any applicable Federal or State law, or the consent by them to the filing of such petition or to the appointment
of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company,
Holdings or any Significant Subsidiary or of any substantial part of their property, or the making by them of an


 









     


     


    

 


assignment for the benefit of creditors, or the admission by
them in writing of their inability to pay their debts generally as they become due; and


 


(i) there occurs any other Event of Default
provided pursuant to Section 301 or 901 of the Indenture with respect to the Notes.


 


“Significant Subsidiary” means
any Subsidiary that would constitute a “significant subsidiary” within the meaning of Article 1 of Regulation S-X of
the Securities Act of 1933 as in effect on the date of the Indenture.


 


If any Event of Default as described in clause
(a), (b), (c), (d), (e), (f) or (i) occurs and is continuing, then in every such case the Trustee or the Holders of not less than
25% in principal amount of the Notes may declare the principal amount of all of the Notes and any accrued and unpaid cash interest
through the date of such declaration, to be due and payable immediately, by a notice in writing to the Company (and to the Trustee
if given by Holders), and upon any such declaration such principal amount shall become immediately due and payable. At any time
after such a declaration of acceleration with respect to the Notes has been made and before a judgment or decree for payment of
the money due has been obtained by the Trustee as provided in Article Five of the Indenture, the Holders of a majority in principal
amount of the Notes by written notice to the Company, Holdings and the Trustee, may rescind and annul such declaration and its
consequences if the Company has complied with the requirements of Section 502 of the Indenture. In the case of an Event of Default
arising from certain events of bankruptcy or insolvency as described in clause (g) and (h) above, all outstanding Notes will become
due and payable immediately without further action. Holders of the Notes may not enforce the Indenture or the Notes except as provided
in the Indenture. Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to
the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences
hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on,
the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and
the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying
such Default or Event of Default.


 


17.             
Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits
from, and perform services for the Company and Holdings and their Affiliates, and may otherwise deal with the Company and Holdings
and their Affiliates, as if it were not the Trustee.


 


18.             
No Recourse Against Others. No director, officer, employee, incorporator or shareholder of the Company or the Guarantors,
as such, shall have any liability for any obligations of the Company or the Guarantors under the Notes, the Guarantees or the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting
a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.
Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the U.S. Securities
and Exchange Commission that such a waiver is against public policy.

as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.


 


22.

as set forth Articles Sixteen and Seventeen of the Indenture.

rank equal in right of payment to all of the existing and future unsecured and unsubordinated indebtedness of the Company and the
Guarantors, respectively.


 


24.             
Defeasance and Covenant Defeasance. The Indenture contains provisions for defeasance at any time of (a) the entire
indebtedness with respect to the Notes and (b) certain covenants, consolidations, merger, conveyance, transfer or lease, in each
case upon compliance by the Company with certain conditions set forth in the Indenture.
