 [FORM OF REVERSE OF NOTE] 

Endologix, Inc. 
 5.0% Voluntary
Convertible Senior Secured Note due 2024 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 5.0%
Voluntary Convertible Senior Secured 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 February 24, 2020 (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. 
 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.

 CASH PAYMENT INSTRUCTIONS 

The undersigned directs that any cash payment owed for fractional shares (and, if applicable, for any accrued but unpaid interest which may be

 Bank:

 Name of Account:
                                         
                                         

ABA No.:
                                         
                                         
                












 Account No.:
                                        

 To avoid the application of “backup withholding” under U.S. federal income tax law, each converting holder (or other payee) should complete,
sign, and deliver an Internal Revenue Service (“IRS”) Form W-9 (in the case of a U.S. person or a resident alien) or an IRS Form W-8BEN or other appropriate
IRS Form W-8 (in the case of a foreign holder). IRS Forms W-9 and W-8 are available on the IRS’s website at
http://www.irs.gov/. Failure to include a properly completed IRS Form W-9 or applicable IRS Form W-8 may result in the application of U.S. backup withholding. 

In addition, Notes surrendered for conversion during the period from the Close of Business on any Record Date to the Open of Business on the immediately
following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted, except as specified below. THE INDENTURE REQUIRES THIS CASH PAYMENT EVEN IF THE INTEREST PAYABLE ON THE IMMEDIATELY
FOLLOWING INTEREST PAYMENT DATE IS PAYABLE IN PIK NOTES OR SHARES OF COMMON STOCK. IN THIS EVENT, EVEN THOUGH THE HOLDER HAS REMITTED A CASH PAYMENT WITH THE CONVERSION NOTICE, THE HOLDER WILL NOT RECEIVE ANY CASH AS THE INTEREST PAYMENT BUT WILL
RECEIVE ONLY PIK NOTES OR SHARES OF COMMON STOCK.    However, such payment need not be made: (i) if the conversion follows the Record Date immediately preceding the Maturity Date; (ii) if the Issuer has
specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the first Business Day immediately following the corresponding Interest Payment Date; or (iii) to the extent of any Defaulted Amounts, if any
Defaulted Amounts exist at the time of conversion with respect to such Note. Where payment is owed, no conversion will occur before this payment has been received by the Issuer. Wiring instructions for any such payment of funds may be obtained by
contacting the Trustee at svilhauer@WilmingtonTrust.com.
