 [FORM OF REVERSE OF NOTE] 

Endologix, Inc. 
 5.0% Mandatory
Convertible Senior Note due 2024 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its
5.0% Mandatory Convertible Senior Notes due 2024 (the “Notes”), limited to the aggregate principal amount of $[            ], all issued or to be issued under and pursuant
to an Indenture dated as of April [    ], 2019 (the “Indenture”), between the Company and Wilmington Trust, National Association (the “Trustee”), 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 will make all
payments and deliveries in respect of conversions, the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date (if applicable) 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 will 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. 

Each Holder shall have the right to receive payment or delivery, as the case may be, of (x) the principal (including the
Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) 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, or through an increase of the principal amount of the outstanding Notes or the issuance of paid-in-kind Notes, as the case may be, herein
prescribed. 

  
 A-5 













 The Notes are issuable in registered form without coupons in minimum
denominations of $1.00 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. 

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 $1.00 or integral multiples 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 Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1.00 or an integral multiple thereof, into
cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s election, at the Applicable Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
