This PATENT SECURITY AGREEMENT (this “Patent Security Agreement”) is made this
9th day of August, 2018, by and among the Grantors listed on the signature pages
hereof (collectively, jointly and severally, “Grantors” and each individually
“Grantor”), and DEERFIELD ELGX REVOLVER, LLC, a Delaware limited liability
company, in its capacity as agent for each member of the Lender Group (in such
capacity, together with its successors and assigns in such capacity, “Agent”).

W I T N E S S E T H:

WHEREAS, pursuant to that certain Credit Agreement dated as of August 9, 2018
(as amended, restated, supplemented, or otherwise modified from time to time,
the “Credit Agreement”) by and among ENDOLOGIX, INC., a Delaware corporation
(“Endologix”), each of its direct and indirect Subsidiaries set forth on the
signature pages thereto and any additional borrower that may thereafter be added
to the Credit Agreement (individually as a “Borrower”, and collectively with any
entities that become party thereto as Borrower and each of their successors and
permitted assigns, the “Borrowers”), the lenders party thereto as “Lenders”
(such Lenders, together with their respective successors and assigns in such
capacity, each, individually, a “Lender” and, collectively, the “Lenders”), and
Agent, the Lender Group has agreed to make certain financial accommodations
available to the Borrowers from time to time pursuant to the terms and
conditions thereof;

WHEREAS, the members of the Lender Group are willing to make the financial
accommodations to the Borrowers as provided for in the Credit Agreement and the
other Loan Documents, but only upon the condition, among others, that Grantors
shall have executed and delivered to Agent, for the benefit of the Lender Group,
that certain Guaranty and Security Agreement, dated as of August 9, 2018
(including all annexes, exhibits or schedules thereto, as from time to time
amended, restated, supplemented or otherwise modified, the “Guaranty and
Security Agreement”); and

WHEREAS, pursuant to the Guaranty and Security Agreement, Grantors are required
to execute and deliver to Agent, for the benefit of the Lender Group, this
Patent Security Agreement.

NOW, THEREFORE, in consideration of the premises and mutual covenants herein
contained and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, each Grantor hereby agrees as
follows:

1. DEFINED TERMS. All initially capitalized terms used but not otherwise defined
herein have the meanings given to them in the Guaranty and Security Agreement
or, if not defined therein, in the Credit Agreement, and this Patent Security
Agreement shall be subject to the rules of construction set forth in
Section 1.04 of the Credit Agreement, which rules of construction are
incorporated herein by this reference, mutatis mutandis.

2. GRANT OF SECURITY INTEREST IN PATENT COLLATERAL. Each Grantor hereby
unconditionally grants, assigns, and pledges to Agent, for the benefit of each
member of the Lender Group, to secure the Secured Obligations, a continuing
security interest

 

1

--------------------------------------------------------------------------------

(referred to in this Patent Security Agreement as the “Security Interest”) in
all of such Grantor’s right, title and interest in and to the following, whether
now owned or hereafter acquired or arising (collectively, the “Patent
Collateral”):

(a) all of its Patents and Patent Intellectual Property Licenses to which it is
a party including those referred to on Schedule I;

(b) all divisionals, continuations, continuations-in-part, reissues,
reexaminations, or extensions of the foregoing; and

(c) all products and proceeds of the foregoing, including any claim by such
Grantor against third parties for past, present or future infringement of any
Patent or any Patent exclusively licensed under any Intellectual Property
License, including the right to receive damages, or right to receive license
fees, royalties, and other compensation under any Patent Intellectual Property
License.

3. SECURITY FOR SECURED OBLIGATIONS. This Patent Security Agreement and the
Security Interest created hereby secures the payment and performance of the
Secured Obligations, whether now existing or arising hereafter. Without limiting
the generality of the foregoing, this Patent Security Agreement secures the
payment of all amounts which constitute part of the Secured Obligations and
would be owed by Grantors, or any of them, to Agent, the other members of the
Lender Group or any of them, whether or not they are unenforceable or not
allowable due to the existence of an Insolvency Proceeding involving any
Grantor.

4. PROTECTION OF PATENT SECURITY INTEREST BY GRANTORS. Each Grantor shall, at
its sole cost, expense and risk, in connection with the operation of its
business, comply with the requirements set forth in Section 6 of the Guaranty
and Security Agreement in respect of the Patent Collateral.

5. REPRESENTATIONS AND WARRANTIES. Each Grantor represents and warrants that:

(a) Schedule I hereto is a true, correct and complete list of all Patents and
Patent Intellectual Property Licenses in which each Grantor purports to have an
ownership or license interest.

(b) Such Grantor has the legal right and authority to enter into this Patent
Security Agreement and perform its terms.

(c) If such Grantor amends its name, such Grantor shall provide copies of such
amendment documentation to Agent and shall, if necessary, re-register such
Grantor’s Patents and Patent Intellectual Property Licenses with the appropriate
Governmental Authority and shall execute and deliver such agreements or
documentation as Agent shall reasonably request in writing to maintain a
perfected first priority security interest in the Patent Collateral subject to
Permitted Liens.

6. SECURITY AGREEMENT. The Security Interest in the Collateral granted pursuant
to this Patent Security Agreement is granted in conjunction with the security
interests

 

2

--------------------------------------------------------------------------------

granted to Agent, for the benefit of the Lender Group, pursuant to the Guaranty
and Security Agreement. Each Grantor hereby acknowledges and affirms that the
rights and remedies of Agent with respect to the Security Interest in the Patent
Collateral made and granted hereby are more fully set forth in the Guaranty and
Security Agreement, the terms and provisions of which are incorporated by
reference herein as if fully set forth herein. To the extent there is any
inconsistency between this Patent Security Agreement and the Guaranty and
Security Agreement, the Guaranty and Security Agreement shall control.

7. AUTHORIZATION TO SUPPLEMENT. If any Grantor shall obtain rights to any new
patent application or issued patent or become entitled to the benefit of any
patent application or patent for any divisional, continuation,
continuation-in-part, reissue, or reexamination of any existing patent or patent
application, the provisions of this Patent Security Agreement shall
automatically apply thereto. Each Grantor shall notify Agent of applications
filed for the registration of any Patents with the United States Patent Office
in accordance with Section 5.7(g) of the Guaranty and Security Agreement.
Without limiting Grantors’ obligations under this Section, Grantors hereby
authorize Agent unilaterally to modify this Patent Security Agreement by
amending Schedule I to include any such new patent rights of each Grantor.
Notwithstanding the foregoing, no failure to so modify this Patent Security
Agreement or amend Schedule I shall in any way affect, invalidate or detract
from Agent’s continuing security interest in all Collateral, whether or not
listed on Schedule I.

8. NO VIOLATION OF LOAN DOCUMENTS. The representations, warranties or covenants
contained herein are supplemental to those representations, warranties and
covenants contained in the other Loan Documents, and shall not be deemed to
modify any such representation, warranty or covenant contained in any other Loan
Document.

9. GRANTOR’S RIGHTS TO ENFORCE PATENTS. Prior to Agent’s giving of notice to
Grantor following the occurrence and during the continuance of an Event of
Default, such Grantor shall have the exclusive right to sue for past, present
and future infringement of the Patent Collateral, including the right to seek
injunctions and/or money damages, in an effort by such Grantor to protect the
Patent Collateral against encroachment by third parties, provided, however,
that:

(a) Any money damages awarded or received by such Grantor on account of such
suit (or the threat of such suit) shall constitute Patent Collateral.

(b) Any damages recovered in any action pursuant to this Section, net of costs
and attorneys’ fees reasonably incurred, shall be applied in accordance with the
Credit Agreement and the Guaranty and Security Agreement.

(c) Following the occurrence and during the continuance of any Event of Default,
Agent, by notice to any Grantor may terminate or limit such Grantor’s rights
under this Section 9.

10. RIGHTS UPON DEFAULT. Upon the occurrence and during the continuance of any
Event of Default, Agent may exercise all rights and remedies as provided for in
the Guaranty and Security Agreement.

--------------------------------------------------------------------------------

11. NO LIMITATION; LOAN DOCUMENTS. This Patent Security Agreement has been
executed and delivered by each Grantor for the purpose of recording the security
interest granted to Agent with respect to the Patent Collateral with the United
States Patent Office. The security interest granted hereby has been granted as a
supplement to, and not in limitation of, the security interest granted to Agent,
for the benefit of the Lender Group, under the Guaranty and Security Agreement
and the other Loan Documents. The other Loan Documents (and all rights and
remedies of Grantor, Agent, and Lenders thereunder) shall remain in full force
and effect in accordance with their terms.

12. TERMINATION; RELEASE OF PATENT COLLATERAL. This Patent Security Agreement
and all obligations of each Grantor and Agent hereunder shall terminate on the
date upon which the Obligations have been Paid in Full. Upon termination of this
Patent Security Agreement, Agent shall, at the reasonable expense of the
Grantor, take such actions required by the Credit Agreement or the Guaranty and
Security Agreement or as otherwise reasonably requested by Grantor to release
its security interest in the Patent Collateral.

13. BINDING EFFECT; BENEFITS. This Patent Security Agreement shall be binding
upon each Grantor and its successors and assigns, and shall inure to the benefit
of Agent, Lenders and their respective successors and assigns.

14. COUNTERPARTS. This Patent Security Agreement is a Loan Document. This Patent
Security Agreement may be executed in any number of counterparts and by
different parties on separate counterparts, each of which, when executed and
delivered, shall be deemed to be an original, and all of which, when taken
together, shall constitute but one and the same Patent Security Agreement.
Delivery of an executed counterpart of this Patent Security Agreement by
telefacsimile or other electronic method of transmission shall be equally as
effective as delivery of an original executed counterpart of this Patent
Security Agreement. Any party delivering an executed counterpart of this Patent
Security Agreement by telefacsimile or other electronic method of transmission
also shall deliver an original executed counterpart of this Patent Security
Agreement but the failure to deliver an original executed counterpart shall not
affect the validity, enforceability, and binding effect of this Patent Security
Agreement.

15. CHOICE OF LAW AND VENUE, JURY TRIAL WAIVER, AND JUDICIAL REFERENCE
PROVISION. THIS PATENT SECURITY AGREEMENT SHALL BE SUBJECT TO THE PROVISIONS
REGARDING CHOICE OF LAW AND VENUE, JURY TRIAL WAIVER, AND JUDICIAL REFERENCE SET
FORTH IN SECTIONS 8.11 AND 8.12 OF THE GUARANTY AND SECURITY AGREEMENT, AND SUCH
PROVISIONS ARE INCORPORATED HEREIN BY THIS REFERENCE, MUTATIS MUTANDIS.
