                       2004 PERFORMANCE COMPENSATION PLAN

      1.1 PURPOSE. The Plan is hereby established by the Company for the purpose
of providing deferred compensation for certain employees who are highly
compensated employees. The deferred compensation that a Participant may receive
pursuant to the Plan will be based upon the appreciation, if any, in the value
of the Performance Units granted to the Participant that occurs from the value
placed on such Performance Units as determined by the Committee (as hereinafter
defined) at the time the Performance Units are granted and the date of a
Distribution Event (as hereinafter defined in this Plan), which will be based
upon the value of the shares of the Company's common stock determined in the
manner set forth in Section 2.9 of this Plan.

      1.2 NATURE OF THE PLAN. The Plan is intended to be an unfunded plan within
the meaning of the Employee Retirement Income Security Act of 1974 ("ERISA").
Accordingly, it is intended that the Plan be exempt from the requirements of
Parts II, III and IV of Title I of ERISA pursuant to Sections 201(2), 301(3)

accordance with rules or regulations that have been promulgated by the Committee
in its sole and absolute discretion and has been executed by the Company, is

return to the Company of a duplicate copy of the Award Notice executed by him or

Directors, in its sole and absolute discretion.

      The Board of Directors may, from time to time, revise the foregoing

      2.10 PERFORMANCE UNIT. "Performance Unit" means a unit used by the Plan
for the purpose of measuring a Participant's Distribution Event Benefit if such
Participant is an employee of the Company on the date that any Distribution
Event occurs. For purposes of the Plan, a Participant shall be deemed an
employee on the date of his or her Separation from Service, except that if any
such Separation from Service is due to termination of Participant's employment
by the Company for "Cause" as Cause is defined in Attachment A to such
Participant's Award Notice, then, for purposes of this Plan, the last day of
Participant's employment with the Company shall be deemed to be the day prior to
the date of such Separation from Service.

termination


                                       3
<PAGE>
of a Participant's employment was made for "Cause," Cause shall be defined in
the manner set forth in Attachment A of the Award Notice and not as it is
defined in any employment agreement between the Participant and the Company, and
any termination of a Participant's employment by the Company for any of the
reasons set forth in Attachment A to his or her Award Notice shall, for purposes
of this Plan, constitute a termination of Participant's employment for Cause.

                                    ARTICLE 3

                                  PARTICIPATION

      3.1 ELIGIBILITY. The Committee in its sole discretion may designate those
of the management or highly compensated employees, within the meaning of ERISA,
of the Company to participate in the Plan. The persons eligible to participate
in the Plan as of the Effective Date are those individuals set forth on Exhibit
B attached hereto and incorporated herein by this reference.

shall determine the number of Performance Units to be granted to each
Participant and to determine the time or times when Performance Units will be
granted. An award of Performance Units to a Participant shall be evidenced by an
Award Notice as provided in Section 2.2 hereof.

      4.2 PARTICIPANT ACCOUNTS. The Committee shall establish and maintain in
its books and records a separate, unfunded Account for the purpose of recording
the value of each Participant's Performance Units under the Plan. The Account
shall be a bookkeeping entry and shall not entitle any Participant to any asset
or assets of the Company.

      4.3 BENEFITS UNFUNDED. The benefits under this Plan shall not be funded,
but shall constitute an unsecured liability payable, when due, by the Company
out of its general assets. Each Participant is required to rely solely upon the
Company's unsecured promise to pay the benefits. In the event of a bankruptcy or
insolvency of the Company, each Participant will be only a general creditor of
the Company with respect to his benefits under the Plan.

                                    ARTICLE 5

                         VALUATION OF PERFORMANCE UNITS

      5.1 VALUE UPON GRANT. Within thirty days of the grant of any Performance
Unit or Units to any Participant, the Committee shall provide such Participant
with a notice setting forth the value that the Committee, in its sole and
absolute discretion, has ascribed, as of the date of grant, to each such
Performance Unit. Such value per Unit (the "Base Value") may be less than, equal
to or greater than, the Fair Market Value of a share of common stock of the
Company as of the date of grant, which shall be determined in the manner set
forth in Section 2.8 hereof (as the same may be


                                       4
<PAGE>
amended from time-to-time by the Committee as provided therein). The Committee
shall maintain adequate records of its determinations with respect to the Base
Value of each Performance Unit granted under this Plan.

      5.2 VALUE UPON PAYMENT OF ACCOUNT. In the event a Distribution Event
occurs with respect to a Participant, the Committee shall provide the
Participant with a notice setting forth the Fair Market Value of each of his or
her vested Performance Units as of the date of the Distribution Event and the
amount of the Distribution Event Benefit that will become payable to the
Participant.

                                    ARTICLE 6

         VESTING; TERMINATION OF PERFORMANCE UNITS; PAYMENT OF BENEFITS

      6.1 VESTING AND TERMINATION OF PERFORMANCE UNITS. A Participant's
Performance Units shall vest in accordance with the vesting schedule set forth
in his or her Award Notice. If, as to a Participant, there is a Separation from
Service prior to a Distribution Event for any reason whatsoever, and whether for
or without Cause, then, all Performance Units that had not become vested on or
before the day prior to the date of the Separation from Service shall
automatically terminate and no Distribution Event Benefit or other benefit shall
be or become payable in respect thereof. If, as to a Participant, there occurs a
Separation from Service due to a termination of Participant's employment by the
Company for Cause, as "Cause" is defined in Attachment A to such Participant's
Award Notice, then, notwithstanding any provision of this Plan to the contrary,
such Participant's vested Performance Units, in addition to the Performance
Units that are unvested, shall automatically terminate upon such Separation from
Service and such Participant shall not be entitled to any Distribution Event
Benefit or other benefit under this Plan.

      6.2 DISTRIBUTION OF BENEFITS. Following the occurrence of a Distribution
Event applicable to any Participant, and provided that the Participant was an
employee of the Company on the date of the occurrence of such Distribution
Event, the Participant shall become entitled to receive the Distribution Event
Benefit that is payable in respect of his or her vested Performance Units, net
of any amounts required to be withheld as provided in Section 6.5 hereof
("Withholdings"), as follows:

            (A) If the Distribution Event is a Change of Control, the
Distribution Event Benefit, net of Withholdings, shall be payable by the Company
within ninety (90) days after the consummation of such Change of Control;

            (B) If the Distribution Event is Participant's Separation from
Service for any reason other than a termination of Participant's employment by
the Company for Cause, the Distribution Event Benefit, net of Withholdings,
shall be payable by the Company within ninety (90) days after the Participant's
Separation from Service; and

            (C) If the Distribution Event is the receipt of a Notice of Exercise
by the Company from a Participant at any time after the expiration of eighteen
(18) months from the date of the grant of the Performance Units to such
Participant (the Eighteen Month Anniversary), and provided that no other
Distribution Event has occurred between the date of grant and such Eighteen


                                       5
<PAGE>
Month Anniversary, the Distribution Event Benefit, net of Withholdings, shall be
payable by the Company within ninety (90) days after the Company's receipt of
the Notice of Exercise.

      Notwithstanding the foregoing, payment of any Distribution Event Benefit
by the Company may be deferred or delayed for good cause. As used herein "good
cause" shall mean any legitimate reason for such delay such as limitations upon
available cash to the Company, limitations imposed upon the Company under any
loan or credit or other agreement with an unrelated third party, other than a
Person that is participating or is a party to a Change of Control of the Company
or any other good faith reasonable cause for such delay, as determined in good
faith by the Committee. Payment of the Distribution Event Benefit shall be in
the form of cash.

      6.3 PAYMENT OF BENEFITS. All payments under the Plan shall be delivered in
person or mailed to the last address of a Participant. Each Participant shall be
responsible for furnishing the Company with the Participant's correct current
address.

      6.4 CLAIMS PROCEDURE. In the event a Participant's claim for benefit is
denied (in whole or in part), the denial and the appeal of the decision shall be
handled in accordance with the provisions of Department of Labor Regulation
2560.503-1.

      6.5 WITHHOLDING. The Company shall make provision for the reporting and
withholding of any federal, state or local taxes that may be required to be
withheld with respect to the payment of any amounts under this Article. Any
amounts so withheld shall be paid to the appropriate taxing authorities.

      8.1 AMENDMENT AND TERMINATION. The Company reserves the right to amend,

                                 ENDOLOGIX, INC.

                      NOTICE OF AWARD OF PERFORMANCE UNITS

To:   <Insert Name of Participant>


      Endologix, Inc. (the "Company") hereby awards to _____________________
(the "Participant"), as of _________________________________ (the "Grant Date"),
___________________ Performance Units pursuant and subject to the terms and
conditions of Endologix, Inc. 2004 Performance Compensation Plan (the "Plan"), a
copy of which is attached. Terms in this Notice of Award that have initial
capital letters and that are not defined herein, unless the context indicates
otherwise, shall have the meanings set forth in the Plan.

      As of __________________________ , the value of each Performance Unit
granted to _________, as hereinabove provided, has been determined to be $
_______________ , which constitutes the Base Value of each such Performance Unit
(as defined in Section 5.1 of the Plan). For purposes of this award, the Base
Value has been determined by multiplying the fair market value of one share of
the Company's common stock on the Grant Date by fifty percent (50%).

      Your Performance Units shall vest as follows: One third (1/3) of the
Performance Units shall become Vested Performance Units on the first anniversary
of the Grant Date, and thereafter, the balance of the Performance Units shall
become Vested Performance Units in a series of eight (8) successive equal
quarterly installments for each full three-month period of your employment by
the Company, such that 100% of the Performance Units shall become Vested
Performance Units on the third (3rd) anniversary of the Grant Date.

      Notwithstanding the foregoing, in the event of a Change in Control of the
Company (as defined in Section 2.3 of the Plan), your unvested Performance Units
shall accelerate automatically and vest in full effective as of immediately
prior to the consummation of the Change in Control.

      You will be eligible to receive payment with respect to your vested
Performance Units upon the occurrence of a Distribution Event, as defined in
Section 2.6 of the Plan.

      Unvested Performance Units will terminate automatically on a Separation
from Service for any reason whatsoever. "Separation from Service" is defined in
Section 2.11 of the Plan. Vested Performance Units also shall terminate
automatically if your employment is terminated by the Company due to one of the
events constituting "Cause" as such term is defined in Attachment A to this
Notice of Award, even if you are employed under an employment agreement with the
Company


                                      C-1
<PAGE>
and such termination does not constitute a termination for "Cause" as
defined in such employment agreement.

      You may exercise your right to receive payment with respect to any or all
vested Performance Units after the eighteen (18) month anniversary of the Grant
Date by delivering a "Notice of Exercise" (in substantially the form as Exhibit
D attached hereto) to the Company at its principal executive offices. However,
in no event shall you be entitled to receive payment with respect to any
Performance Units which have not vested in accordance with this Award Notice.
