                             VIII. INDEMNIFICATION

        (A) With the exception of any actions or claims covered by Section
VIII(B), Endologix agrees to defend, indemnify ad hold harmless IMPRA and its
parents, subsidiaries, affiliates, successors, assigns, officers, directors,
employees and agents from and against all claims, demands, costs, expenses,
suits, proceedings, actions, causes of action, damages (including incidental,
consequential or punitive damages), liabilities, judgments, fines or penalties
of any kind or description whatsoever, including reasonable expenses of
investigation and reasonable attorneys' fees (hereinafter "Claims") arising from
personal injury, wrongful death, property damage or commercial loss, or any
other losses or damages of any kind or description whatsoever that arise from,
are connected with, or relate to, on or after the date of this Agreement, use of
the Components by Endologix or the sale or use of medical devices made from
Components sold by IMPRA to Endologix; provided, however, the provisions of this
Section VIII(A) shall not apply to the extent that the provisions of Section
4.4(b) of the International Distributor Agreement ("Distributor Agreement") by
and between IMPRA and Endologix apply to make the indemnification and other
obligations provided in Section 4.4(a) of the Distributor Agreement
inapplicable. The parties shall give each other prompt written notice of any
Claim which is or may be subject to the indemnity set forth herein and Endologix
and IMPRA shall cooperate fully in relation to any such Claim, including making
available documents and witnesses in response to discovery requests or otherwise
assisting in the defense of any such Claim. Endologix shall have the right to
select counsel with respect to any Claim, provided, however IMPRA may
participate in any such Claim by counsel o fits own choice and at its own
expense. IMPRA shall not settle any claim for which indemnification is or may be
sought without Endologix' prior written approval, which shall not be
unreasonably withheld. Endologix shall make no settlement of any Claim which
Endologix has undertaken to defend without IMPRA's consent, unless (i) Endologix
fully indemnifies IMPRA in connection therewith, (ii) there is no admission of
violation of law, negligence or fault of any kind by or on behalf of IMPRA,
(iii) the relief agreed to in connection therewith requires no action, payment
or financial undertaking by or on the part of IMPRA and is not reasonably likely
to restrict or otherwise interfere with IMPRA's ability to conduct its business,
and (iv) IMPRA receives a general release of liability reasonably satisfactory
to it.

        (B) IMPRA agrees to defend, indemnify and hold harmless Endologix and
its parents, subsidiaries, affiliates, successors, assigns, shareholders,
directors, officers, employees and agents from and against all claims, demands,
costs, expenses, suits, proceedings, actions, causes of action, damages
(including incidental, consequential or punitive damages), liabilities,
judgments, fines or penalties of any kind or description whatsoever, including
reasonable expenses of investigation and reasonable attorneys' fees, arising
solely from the failure of the Components to conform to the specifications of
the Components. Endologix will promptly notify IMPRA of any claims which may be
the subject of indemnity under this Agreement. IMPRA may, at its option and at
its expense, assume the defense and control of any claim or lawsuit brought
against Endologix and subject to this indemnity, using counsel selected by IMPRA
with the consent of Endologix, which consent will not be unreasonably withheld.
Endologix may be represented in such litigation by its own counsel at its own
expense. IMPRA will not enter any settlement which may be the subject of this
indemnity without the consent of Endologix, which consent will not be
unreasonably withheld.

need for access to the Confidential Information. Upon termination of this
Agreement, each party will return the Confidential Information of the other or
dispose of such Confidential Information and all copies of it, except (i) as

continue for an initial term of five years; notwithstanding the foregoing, this
Agreement may be sooner terminated by Endologix by providing IMPRA with six (6)
months' prior notice that Endologix will manufacture components in-house without
use of any IMPRA confidential information or proprietary rights. Thereafter,
this Agreement shall terminate automatically, without notice, unless prior to
that time the term of the Agreement is extended by mutual consent of the
parties. Following termination the provisions of this Agreement will continue to

the domestic laws of the State of Arizona without giving effect to any choice or
conflict of law provision or rule (whether of the State of California or any
other jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of Arizona.

        (B) Except as provided in Section 11 hereof, in the event that at
anytime hereafter there arises any disagreement, controversy or dispute between
the parties hereto with respect to the enforcement, violation or interpretation
of this Agreement, or of the operations hereunder or of the respective rights
and liabilities of the parties hereto, then, upon written demand of any party
hereto, said demand setting forth each matter or matters upon which the parties

days' written notice, such controversy or dispute shall be settled by
arbitration before one arbitrator in accordance with the Commercial Arbitration

rendered by the arbitrators may be entered in any court having jurisdiction
thereof. Each party hereto agrees to consider himself or itself bound and to be
bound by any award made by the arbitrators pursuant to this Agreement.

                         AMENDMENT TO SUPPLY AGREEMENT

        This Amendment to Supply Agreement (this "Amendment") is entered into as
of January 17th, 2002 by and between IMPRA, Inc., a subsidiary of C.R. Bard,
Inc., 1625 W. 3rd Street, Tempe, AZ 85281 ("IMPRA") and Endologix, Inc. a
Delaware corporation, with offices at 13700 Alton Parkway, Suite 160, Irvine,
California 92618 ("Endologix").

                                 R E C I T A L S

        WHEREAS, IMPRA and Endologix are parties to that certain Supply
Agreement dated February 12, 1999 (as amended and/or supplemented to date, the
"Supply Agreement"); and

        WHEREAS, IMPRA and Endologix desire to amend the Supply Agreement on the
terms and conditions set forth herein.

                                    AGREEMENT

        In consideration of the foregoing premises, the mutual covenants and
agreements set forth herein, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
hereby agree as follows:

        1. Definitions. For purposes of this Amendment, unless otherwise set
forth herein, capitalized terms established in the Supply Agreement shall be
applied herein as defined therein.

        2.     Amendments.

               a. Section (B) of Article IV of the Supply Agreement is hereby
amended to read in its entirety as follows:

                      "Price and Payment. The price paid and terms of payment
               for any Components purchased from time to time by Endologix from
               IMPRA for use in Implanted Devices shall be as set forth on
               Exhibit B attached to this Amendment. Commencing on the date that
               all the Conditions (as hereinbelow defined) are met, the price
               paid and terms of payment for Components purchased for Implanted
               Devices from time to time by Endologix from IMPRA shall be as set
               forth on Exhibit C attached to this Amendment. The "Conditions"
               are as follows: (1) the issuance of a patent to Dr. David
               Goldfarb for an artificial vascular prosthesis arising from the
               recently concluded patent interference in Dr. Goldfarb's U.S.
               Patent Application Serial No. 05/517,415 (the "Goldfarb Patent
               Issuance") by the United States Patent and Trademark Office, and
               (2) Endologix receives FDA approval to commercially distribute
               the Implanted Devices in the United States. The parties hereby
               agree that the price paid for the Components shall be increased
               each year commencing January 1, 2003, to take into account any
               price increases

                                      -1-

               which are tied to the Consumer Price Index published by the
               United States Department of Labor, Bureau of Labor Statistics."
               The minimum purchases of the Components by Endologix for the
               calendar year 2001 shall be 2,500 units. The minimum purchases of
               Components by Endologix for the calendar year 2002 shall be 2,900
               units. The minimum purchases of Components by Endologix for the
               calendar year 2003 shall be the greater of (i) actual units
               purchased in calendar year 2002 or (ii) the minimum purchase
               requirements for calendar year 2002, plus 10% (in either case).
               Minimum purchases of Components by Endologix for each calendar
               year thereafter shall be equal to not less than 115% of the
               previous year's minimum or actual purchases, whichever is higher.

               b. Article X of the Supply Agreement is hereby amended to read in
its entirety as follows:

                      "This Agreement will come into effect on the Effective
               Date and will continue until December 31, 2007. Thereafter, this
               Agreement shall renew automatically, on a year by year basis, for
               additional one year periods without notice, unless one party
               provides notice to the other party of its intention not to renew
               within thirty (30) days from the expiration of the applicable
               renewal period. Following termination, the provisions of this
               Agreement will continue to apply to Components sold to Endologix
               during the term of this Agreement."

               c. Section (A) of the Article XII of the Supply Agreement is
hereby amended to read in its entirety as follows:

                      "Subject to the immediately succeeding sentence, this
               Agreement shall be binding upon and inure to the benefit of the
               parties named herein and their respective successors and
               permitted assigns. Endologix (and its successors or assignees)
               may assign this Agreement and its rights under this Agreement to
               purchase and manufacture Components at the prices specified
               herein (i) to an affiliate, (ii) in connection with the sale,
               transfer, license, or other disposition of all or substantially
               all of its assets, (iii) in connection with the sale of capital
               stock constituting more than 50% of its total voting power,
               and/or (iv) in connection with a merger, recapitalization or
               reorganization. Each of Endologix and IMPRA agree that following
               the occurrence of any of the events described in items (i)
               through (iv) above, Endologix (and any successors or assignees)
               will be entitled to purchase from IMPRA only those Components
               being purchased from IMPRA prior to the occurrence of such event
               in accordance with the then-existing Specifications."

               d. A new Section (F) is hereby added to Article XII of the Supply
Agreement to read in its entirety as follows:

                      "Endologix and IMPRA each agree to use commercially
               reasonable efforts to agree upon development costs for Components
               to be used in new Implanted Devices."

               a. Entire Agreement. The Supply Agreement, as amended by this
Amendment, constitutes the entire agreement among the parties pertaining to the
subject matter hereof and supersedes all prior agreements, understandings,

counterparts, each of which shall be deemed an original instrument and all of

Supply Agreement shall remain unchanged and shall continue in full force and
effect. In the event of a conflict between this Amendment and the Supply
