 [FORM OF REVERSE OF NOTE] 

Atlas Air Worldwide Holdings, Inc. 

2.25% Convertible Senior Note due 2022 

This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.25% Convertible Senior Notes due 2022 (the
“Notes”), limited to the aggregate principal amount of $224,500,000 all issued or to be issued under and pursuant to the First Supplemental Indenture dated as of June 3, 2015 (the “First Supplemental
Indenture”), between the Company and Wilmington Trust, National Association (the “Trustee”), which amends and supplements the Indenture dated as of June 3, 2015 between the Company and the Trustee (the “Base
Indenture” and, as amended and supplemented by the First Supplemental Indenture and from time to time with respect to the Notes, the “Indenture”) to which Indenture and all indentures supplemental thereto reference is
hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount,
subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined in this Note shall have the respective meanings set forth in the Indenture. 

In case certain Events of Default shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by
either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then Outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set
forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company shall make all payments and deliveries in
respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect
of the Note. The Company shall pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the
Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may on
behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 
 No
reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay 

  
 A-5 








 
or deliver, as the case may be, the principal (including the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on, and the consideration due upon conversion of,
this Note at the place, at the respective times, at the rate and in the lawful money or shares of Common Stock, as the case may be, herein prescribed. 

The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples in excess
thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized
denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder
of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 

The Notes are not subject to redemption through the operation of any sinking fund or otherwise. 

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to repurchase for
cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples in excess thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price. 

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the occurrence of
certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple in excess
thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
