SECTION 3

Administration




     The Plan shall be administered by the Committee. A majority of the Committee shall constitute
a quorum, and the acts of the members of the Committee who are present at any meeting thereof at
which a quorum is present, or acts unanimously approved by the members of the Committee in writing,
shall be the acts of the Committee. Subject to the following and applicable law, the Committee, in
its sole discretion, may delegate any or all of its powers and duties under the Plan, including the
power to grant Awards under the Plan, to the Chief Executive Officer of the Company, subject to
such limitations on such delegated powers and duties as the
Committee may impose, if any. Upon any such delegation, all references in the Plan to the
“Committee”, other than in Section 7, shall be deemed to include the Chief Executive Officer;
provided, however, that such delegation shall not limit the Chief Executive Officer’s right to
receive Awards under the Plan. Notwithstanding the foregoing, the Chief Executive Officer may not
grant Awards to, or take any action with respect to any Award previously granted to, a person who
is an officer subject to Rule 16b-3 or a Director. Subject to the terms of the Plan and applicable
law, and in addition to other express powers and authorizations conferred on the Committee by the
Plan, the Committee shall have full power and authority to: (i) designate Participants; (ii)
determine the type or types of Awards to be granted to a Participant; (iii) determine the number of
Units to be covered by Awards; (iv) determine the terms and conditions of any Award; (v) determine
whether, to what extent, and under what circumstances Awards may be settled, exercised, canceled,
or forfeited; (vi) interpret and administer the Plan and any instrument or agreement relating to an
Award made under the Plan; (vii) establish, amend, suspend, or waive such rules and regulations and
appoint such agents as it shall deem appropriate for the proper administration of the Plan; (viii)
make any other determination and take any other action that the Committee deems necessary or
desirable for the administration of the Plan; and (ix) ensuring the payment of any Award or benefit
hereunder is made in full compliance with the requirements of Code Section 409A. The Committee may
correct any defect or supply any omission or reconcile any inconsistency in the Plan or an Award
Agreement in such manner and to such extent as the Committee deems necessary or appropriate.
Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations,
and other decisions under or with respect to the Plan or any Award shall be within the sole
discretion of the Committee, may be made at any time and shall be final, conclusive, and binding
upon all Persons, including the Partnership, the Company, any Affiliate, any Participant, and any
Participant’s beneficiary of any Award.



SECTION 4

Units




     (a) Limits on Units Deliverable. Subject to adjustment as provided in Section 4(c),
the total aggregate number of Units that may be delivered with respect to Awards under the Plan is
two million two hundred fifty thousand (2,250,000); provided, however, that Units withheld from an
Award to either satisfy the Company’s or an Affiliate’s tax withholding obligations with respect to
the Award or pay the exercise price of an Award shall not be considered to be Units delivered under
the Plan for this purpose. If any Award is forfeited, cancelled, exercised, paid, or otherwise
terminates or expires without the actual delivery of Units pursuant to such Award (the grant of
Restricted Units is not a delivery of Units for this purpose), the Units subject to such Award
shall again be available for Awards under the Plan. There shall not be any limitation on the
number of Awards that may be paid in cash.



     (b) Sources of Units Deliverable Under Awards. Any Units delivered pursuant to an
Award shall consist, in whole or in part, of Units acquired in the open market, from the Company,
the Partnership, any Affiliate or any other Person, or any combination of the foregoing, as
determined by the Committee in its discretion.



     (c) Anti-dilution Adjustments. With respect to any “equity restructuring” event that
could result in an additional compensation expense to the Company pursuant to the provisions of
Financial Accounting Standard (“FAS”) 123R if adjustments to Awards with respect to such event were
discretionary, the Committee shall equitably adjust the number and type of Units covered by each
outstanding Award and the terms and conditions, including the exercise price and performance
criteria (if any), of such Award to equitably reflect such restructuring event and shall adjust the
number and type of Units (or other securities or property) with respect to which Awards may be
granted after such event. With respect to any other similar event that would not result in a FAS
123R accounting charge if the adjustment to Awards with respect to such event were subject to
discretionary action, the Committee shall have complete discretion to adjust Awards in such manner
as it deems appropriate with respect to such other event. Any such adjustment shall be final,
binding and conclusive on all persons claiming any right or interest under the Plan.



42









 





SECTION 5

Eligibility




     Any Employee or Director shall be eligible to be designated a Participant by the Committee and
receive an Award under the Plan.



SECTION 6

Awards




     (a) Options and UARs. The Committee shall have the authority to determine the
Employees and Directors to whom Options and/or UARs shall be granted, the number of Units to be
covered by each Option or UAR, the exercise price therefor, the Restricted Period and other
conditions and limitations applicable to the exercise of the Option or UAR, including the following
terms and conditions and such additional terms and conditions, as the Committee shall determine,
that are not inconsistent with the provisions of the Plan.




     (i) Exercise Price. The exercise price per Unit purchasable under an Option or
subject to a UAR shall be determined by the Committee at the time the Option or UAR is
granted but may not be less than the Fair Market Value of a Unit as of the date of grant of
the Option or UAR.




     (ii) Time and Method of Exercise. The Committee shall determine the exercise
terms and the Restricted Period with respect to an Option or UAR grant, which may include,
without limitation, a provision for accelerated vesting upon the achievement of specified
performance goals or other events, and the method or methods by which payment of the exercise
price with respect to an Option may be made or deemed to have been made, which may include,
without limitation, cash, check acceptable to the Company, withholding Units from the Award,
a “cashless-broker” exercise through procedures approved by the Company, or any combination
of the above methods, having a Fair Market Value on the exercise date equal to the relevant
exercise price. Options and UARs shall in no event have a term longer than ten (10) years
from the date of grant.




     (iii) Forfeitures. Except as otherwise provided in the Award Agreement related
to the Option or UAR grant, upon termination of a Participant’s employment with the Company
and its Affiliates or membership on the Board, whichever is applicable, for any reason during
the applicable Restricted Period, all unvested Options and UARs shall be forfeited by the
Participant. The Committee may, in its discretion, waive in whole or in part such forfeiture
with respect to a Participant’s Options or UARs.



     (b) Restricted Units and Phantom Units. The Committee shall have the authority to
determine the Employees and Directors to whom Restricted Units and Phantom Units shall be granted,
the number of Restricted Units or Phantom Units to be granted to each such Participant, the
Restricted Period, the conditions under which the Restricted Units or Phantom Units may become
vested or forfeited and such other terms and conditions as the Committee may establish with respect
to such Awards.




     (i) DERs. To the extent provided by the Committee, in its discretion, a grant
of Phantom Units may include a tandem DER grant, which may provide that such DERs shall be
paid directly to the Participant, be credited to a bookkeeping account (with or without
interest in the discretion of the Committee), be “reinvested” in Restricted Units or
additional Phantom Units and be subject to the same or different vesting restrictions as the
tandem Phantom Unit Award, or be subject to such other provisions or restrictions as
determined by the Committee in its discretion. Absent a contrary provision in the Award
Agreement, upon a distribution with respect to a Unit, cash equal in value to such
distribution shall be paid promptly to the Participant without vesting restrictions with
respect to each Phantom Unit then held.




     (ii) UDRs. To the extent provided by the Committee, in its discretion, a grant
of Restricted Units may provide that the distributions made by the Company with respect to
the Restricted Units shall be subject to the same forfeiture and other restrictions as the
Restricted Unit and, if restricted, such distributions shall be held, without interest, until
the Restricted Unit vests or is forfeited with the UDR being paid or forfeited at the same
time, as the case may be. In addition, the Committee may provide that such distributions be
used to acquire additional Restricted Units for the Participant. Such additional Restricted
Units may be subject to such vesting and other terms as the Committee may prescribe. Absent
such a



43









 







restriction on the UDRs in the Award Agreement, upon a distribution with respect to
the Restricted Unit, such distribution shall be paid promptly to the holder of the Restricted
Unit without vesting restrictions.




     (iii) Forfeitures. Except as otherwise provided in the terms of the Restricted
Units or Phantom Units Award Agreement, upon termination of a Participant’s employment with
the Company and/or its Affiliates or membership on the Board, whichever is applicable, for
any reason during the applicable Restricted Period, all outstanding, unvested Restricted
Units and Phantom Units awarded the Participant shall be automatically forfeited on such
termination. The Committee may, in its discretion, waive in whole or in part such forfeiture
with respect to a Participant’s Restricted Units and/or Phantom Units.




     (iv) Lapse of Restrictions.




     (A) Phantom Units. Upon or as soon as reasonably practical following the
vesting of each Phantom Unit, subject to the provisions of Section 8(b), the
Participant shall be entitled to receive from the Company one Unit or cash equal to
the Fair Market Value of a Unit, as determined by the Committee in its discretion.




     (B) Restricted Units. Upon or as soon as reasonably practical following
the vesting of each Restricted Unit, subject to satisfying the tax withholding
obligations of Section 8(b), the Participant shall be entitled to have the
restrictions removed from his or her Unit certificate so that the Participant then
holds an unrestricted Unit.



     (c) Unit Awards. Unit Awards may be granted under the Plan to such Employees and/or
Directors and in such amounts as the Committee, in its discretion, may select.



     (d) Other Unit-Based Awards. Other Unit-Based Awards may be granted under the Plan to
such Employees and/or Directors and in such amounts as the Committee, in its discretion, may
select. An Other Unit-Based Award shall be an award denominated or payable in, valued in or
otherwise based on or related to Units, in whole or in part. The Committee shall determine the
terms and conditions of any such Other Unit-Based Award. Upon vesting, an Other Unit-Based Award
may be paid in cash, common units (including Restricted Units) or any combination thereof as
provided in the Award Agreement.



     (e) General.




     (i) Awards May Be Granted Separately or Together. Awards may, in the discretion
of the Committee, be granted either alone or in addition to, in tandem with, or instead of
any other Award granted under the Plan or any award granted under any other plan of the
Partnership, the Company or any Affiliate. Awards granted in addition to or in tandem with
other Awards or awards granted under any other plan of the Company or any Affiliate may be
granted either at the same time as or at a different time from the grant of such other Awards
or awards.




     (ii) Limits on Transfer of Awards.




     (A) Except as provided in Paragraph (C) below, each Option and Unit Appreciation
Right shall be exercisable only by the Participant during the Participant’s lifetime,
or by the person to whom the Participant’s rights shall pass by will or the laws of
descent and distribution.




     (B) Except as provided in Paragraph (C) below, no Award and no right under any
such Award may be assigned, alienated, pledged, attached, sold or otherwise
transferred or encumbered by a Participant and any such purported assignment,
alienation, pledge, attachment, sale, transfer or encumbrance shall be void and
unenforceable against the Company or any Affiliate.




     (C) To the extent specifically provided by the Committee with respect to an
Option or Unit Appreciation Right, an Option or Unit Appreciation Right may be
transferred by a Participant without consideration to immediate family members or
related family trusts, limited partnerships or similar entities or on such terms and
conditions as the Committee may from time to time establish.



44









 






     (iii) Term of Awards. The term of each Award shall be for such period as may be
determined by the Committee.




     (iv) Unit Certificates. All certificates for Units or other securities of the
Company delivered under the Plan pursuant to any Award or the exercise thereof shall be
subject to such stop transfer orders and other restrictions as the Committee may deem
advisable under the Plan or the rules, regulations, and other requirements of the SEC, any
stock exchange upon which such Units or other securities are then listed, and any applicable
federal or state laws, and the Committee may cause a legend or legends to be inscribed on any
such certificates to make appropriate reference to such restrictions.




     (v) Consideration for Grants. Awards may be granted for such consideration,
including services, as the Committee shall determine.




     (vi) Delivery of Units or other Securities and Payment by Participant of
Consideration. Notwithstanding anything in the Plan or any grant agreement to the
contrary, delivery of Units pursuant to the exercise or vesting of an Award
may be deferred for any period during which, in the good faith determination of the
Committee, the Company is not reasonably able to obtain Units to deliver pursuant to such
Award without violating applicable law or the applicable rules or regulations of any
governmental agency or authority or securities exchange. No Units or other securities shall
be delivered pursuant to any Award until payment in full of any amount required to be paid
pursuant to the Plan or the applicable Award Agreement (including, without limitation, any
exercise price or tax withholding) is received by the Company. Units may be delivered to a
Participant by either a physical certificate or certificates or by the establishment of a
book-entry account with the unit transfer agent.



SECTION 7

Amendment and Termination





Except to the extent prohibited by applicable law:




     (a) Amendments to the Plan. Except as required by the rules of the principal
securities exchange on which the Units are traded and subject to Section 7(b) below, the
Board or the Committee may amend, alter, suspend, discontinue, or terminate the Plan in any
manner, including increasing the number of Units available for Awards under the Plan, without
the consent of any Participant, other holder or beneficiary of an Award, or any other Person.




     (b) Amendments to Awards. Subject to Section 7(a), the Committee may waive any
conditions or rights under, amend any terms of, or alter any Award theretofore granted,
provided no change, other than pursuant to Section 7(c), in any Award shall (i) materially
reduce the rights or benefits of a Participant with respect to an Award without the consent
of such Participant, and/or (ii) result in taxation to the Participant under Code Section
409A unless otherwise determined by the Board.




     (c) Actions Upon the Occurrence of Certain Events. Upon the occurrence of a
Change of Control, any change in applicable law or regulation affecting the Plan or Awards
thereunder, or any change in accounting principles affecting the financial statements of the
Partnership or the Company, the Committee, in its sole discretion, without the consent of any
Participant or holder of the Award, and on such terms and conditions as it deems appropriate,
may take any one or more of the following actions in order to prevent dilution or enlargement
of the benefits or potential benefits intended to be made available under the Plan or an
outstanding Award:




     (i) provide for either (A) the termination of any Award in exchange for an amount
of cash, if any, equal to the amount that would have been attained upon the exercise
of such Award or realization of the Participant’s rights (and, for the avoidance of
doubt, if as of the date of the occurrence of such transaction or event the Committee
determines in good faith that no amount would have been attained upon the exercise of
such Award or realization of the Participant’s rights, then such Award may be
terminated by the Company without payment) or (B) the replacement of such Award with
other rights or property selected by the Committee in its sole discretion;



45









 






     (ii) provide that such Award be assumed by the successor or survivor entity, or a
parent or subsidiary thereof, or be exchanged for similar options, rights or awards
covering the equity of the successor or survivor, or a parent or subsidiary thereof,
with appropriate adjustments as to the number and kind of equity interests and prices;




     (iii) make adjustments in the number and type of Units (or other securities or
property) subject to outstanding Awards, and in the number and kind of outstanding
Awards or in the terms and conditions of (including the exercise price), and the
vesting and performance criteria included in, outstanding Awards, or both;




     (iv) provide that such Award shall be exercisable or payable, notwithstanding
anything to the contrary in the Plan or the applicable Award Agreement; and




     (v) provide that the Award cannot be exercised or become payable after such
event, i.e., shall terminate upon such event.




Notwithstanding the foregoing, with respect to an above event that is an “equity
restructuring” event that would be subject to a compensation expense pursuant FAS 123R, the
provisions in Section 4(c) shall control to the extent they are in conflict with the
discretionary provisions of this Section 7.



SECTION 8

General Provisions




     (a) No Rights to Award. No Person shall have any claim to be granted any Award under
the Plan, and there is no obligation for uniformity of treatment of Participants. The terms and
conditions of Awards need not be the same with respect to each recipient.



     (b) Tax Withholding. Unless other arrangements have been made that are acceptable to
the Company, the Company or any Affiliate is authorized to withhold from any Award, from any
payment due or transfer made under any Award or from any compensation or other amount owing to a
Participant the amount (in cash, Units, Units that would otherwise be issued pursuant to such Award
or other property) of any applicable taxes payable in respect of the grant of an Award, its
exercise, the lapse of restrictions thereon, or any payment or transfer under an Award or under the
Plan and to take such other action as may be necessary in the opinion of the Company to satisfy its
withholding obligations for the payment of such taxes.



     (c) No Right to Employment or Services. The grant of an Award shall not be construed
as giving a Participant the right to be retained in the employ of the Partnership, the Company or
any Affiliate or to remain on the Board, as applicable. Furthermore, the Company or an Affiliate
may at any time dismiss a Participant from employment free from any liability or any claim under
the Plan, unless otherwise expressly provided in the Plan, any Award Agreement or other agreement.



     (d) Governing Law. The validity, construction, and effect of the Plan and any rules
and regulations relating to the Plan shall be determined in accordance with the laws of the State
of Texas without regard to its conflicts of laws principles.



     (e) Severability. If any provision of the Plan or any Award is or becomes or is
deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Award,
or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such
provision shall be construed or deemed amended to conform to the applicable law or, if it cannot be
construed or deemed amended without, in the determination of the Committee, materially altering the
intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, Person
or Award and the remainder of the Plan and any such Award shall remain in full force and effect.



     (f) Other Laws. The Committee may refuse to issue or transfer any Units or other
consideration under an Award if, in its sole discretion, it determines that the issuance or
transfer of such Units or such other consideration might violate any applicable law or regulation,
the rules of the principal securities exchange on which the Units are then traded, or entitle the
Company or an Affiliate to recover the same under Section 16(b) of the Exchange Act, and any
payment tendered to the Company by a Participant, other holder or beneficiary in connection with
the exercise of such Award shall be promptly refunded to the relevant Participant, holder or
beneficiary.



46









 





     (g) Code Section 409A




     (i) The Plan is intended to be administered, operated and construed in compliance with
Section 409A of the Code and any guidance issued thereunder. Notwithstanding this or any
other provision of the Plan to the contrary, the Board or the Committee may amend the Plan in
any manner, or take any other action, that either of them determines, in its sole discretion,
is necessary, appropriate or advisable to cause the Plan to comply with Code Section 409A and
any guidance issued thereunder. Any such action, once taken, shall be deemed to be effective
from the earliest date necessary to avoid a violation of Code Section 409A and shall be
final, binding and conclusive on all Participants and other individuals having or claiming
any right or interest under the Plan.




     (ii) Notwithstanding the provisions of the Plan or any Award Agreement, no payment
pursuant to an Award that is subject to Code Section 409A shall be made to a Participant as a
result of such Participant’s “separation from service” (within the meaning of such phrase in
Code Section 409A), within the six-month period following such separation from service (or,
if earlier, the date of death of the employee), if the Participant is a Specified Employee.
For purposes of the previous sentence the term “Specified Employee” is defined in Code
Section 409A and the authoritative guidance thereunder.



     (h) No Trust or Fund Created. Neither the Plan nor any Award shall create or be
construed to create a trust or separate fund of any kind or a fiduciary relationship between the
Company or any participating Affiliate and a Participant or any other Person. To the extent that
any Person acquires a right to receive payments from the Company or any participating Affiliate
pursuant to an Award, such right shall be no greater than the right of any general unsecured
creditor of the Company or any participating Affiliate.



     (i) No Fractional Units. No fractional Units shall be issued or delivered pursuant to
the Plan or any Award, and the Committee shall determine whether cash, other securities, or other
property shall be paid or transferred in lieu of any fractional Units or whether such fractional
Units or any rights thereto shall be canceled, terminated, or otherwise eliminated.



     (j) Headings. Headings are given to the Sections and subsections of the Plan solely
as a convenience to facilitate reference. Such headings shall not be deemed in any way material or
relevant to the construction or interpretation of the Plan or any provision thereof.



     (k) Facility Payment. Any amounts payable hereunder to any person under legal
disability or who, in the judgment of the Committee, is unable to manage properly his financial
affairs, may be paid to the legal representative of such person, or may be applied for the benefit
of such person in any manner that the Committee may select, and the Company shall be relieved of
any further liability for payment of such amounts.



     (l) Gender and Number. Words in the masculine gender shall include the feminine
gender, the plural shall include the singular and the singular shall include the plural.



     (m) Deferrals. The Committee may, to the extent permitted by applicable law, permit
Participants to defer Awards under the Plan. Any such deferrals shall be subject to such terms,
conditions and procedures that the Committee may establish from time to time in its sole discretion
and consistent with the advance and subsequent deferral requirements of Code Section 409A.



     (n) Unfunded Obligations. Any amounts (deferred or otherwise) to be paid to
Participants pursuant to the Plan are unfunded obligations of the Company and or its Affiliates.
Neither the Partnership nor the Company is required to segregate any monies from its general funds,
to create any trusts or to make any special deposits with respect to such unfunded obligation. The
Committee, in its sole discretion, may direct the Partnership or the Company to share with its
Affiliates the costs of a portion of the Awards paid to Participants. Beneficial ownership of any
investments, including trust investments which the Partnership or the Company may make to fulfill
this obligation, shall at all times remain in the Partnership or the Company, as applicable. Any
investments and the creation or maintenance of any trust or any Participant account shall not
create or constitute a trust or a fiduciary relationship between the Committee, the Partnership,
the Company or any Affiliate and a Participant, or otherwise create any vested or beneficial
interest in any Participant or the Participant’s beneficiary or the Participant’s creditors in any
assets of the Partnership, the Company or its Affiliates whatsoever. The Participants shall have
no claim against the Partnership or the Company for any changes in the value of any assets which
may be invested or reinvested by the Partnership or the Company with respect to the Plan.



47









 





     (o) Forfeiture Events.




     (i) If the Partnership or Company is required to prepare an accounting restatement due
to the material noncompliance of the Partnership or Company, as a result of misconduct, with
any financial reporting requirement under the securities laws, and if a Participant knowingly
engaged in the misconduct, was grossly negligent with respect to such misconduct, or
knowingly or grossly negligently failed to prevent the misconduct (whether or not the
Participant is one of the individuals subject to automatic forfeiture under Section 304 of
the Sarbanes-Oxley Act of 2002), the Participant shall reimburse the Partnership or the
Company the amount of any payment in settlement of an Award earned or accrued during the
twelve-month period following the first public issuance or filing with the SEC (whichever
first occurred) of the financial document embodying such financial reporting requirement.




     (ii) The Committee may specify in an Award Agreement that the Participant’s rights,
payments, and benefits with respect to an Award shall be subject to reduction, cancellation,
forfeiture, or recoupment upon the occurrence of certain specified events, in addition to any
otherwise applicable vesting or performance conditions of an Award. Such events may include,
without limitation, termination of employment for cause, violation of material policies that
may apply to the Participant, breach of noncompetition, confidentiality, or other restrictive
covenants that may apply to the Participant, or other conduct by the Participant that is
