Moreover, in the event of any such transaction or event or in the event of a Change in Control, the Committee, in its discretion, may provide in substitution for any or all outstanding Awards under this Plan such alternative consideration (including cash), if any, as it, in good faith, may determine to be equitable in the circumstances and may require in connection therewith the surrender of all Awards so replaced in a manner that complies with Section 409A of the Code. In addition, for each Option Right or Appreciation Right with an Option Price or Base Price greater than the consideration offered in connection with any such transaction or event or Change in Control, the Committee may in its sole discretion elect to cancel such Option Right or Appreciation Right without any payment to the person holding such Option Right or Appreciation Right. The Committee will also make or provide for such adjustments in the numbers of units specified in Section 3 of this Plan as the Committee in its sole discretion, exercised in good faith, may determine is appropriate to reflect any transaction or event described in this Section 11.

12. Non U.S. Participants.

Moreover, the Committee may approve such supplements to or amendments, restatements or alternative versions of this Plan (including, without limitation, sub-plans) as it may consider necessary or appropriate for such purposes, without thereby affecting the terms of this Plan as in effect for any other purpose, and the Secretary or other appropriate officer of the Partnership may certify any such document as having been approved and adopted in the same manner as this Plan. No such special terms, supplements, amendments or restatements, however, will include any provisions that are inconsistent with the terms of this Plan as then in effect unless this Plan could have been amended to eliminate such inconsistency without further approval by the partners of the Partnership.

13. Transferability.

(a) Except as otherwise determined by the Committee, no Option Right, Appreciation Right, Restricted Unit, Phantom Unit, Performance Unit, Cash Incentive Award, Other Award of this Plan or DER paid with respect to Awards made under this Plan will be transferable by the Participant except by will or the laws of descent and distribution, and in no event will any such Award granted under the Plan be transferred for value. Except as otherwise determined by the Committee, Option Rights and Appreciation Rights will be exercisable during the Participant’s lifetime only by him or her or, in the event of the Participant’s legal incapacity to do so, by his or her guardian or legal representative acting on behalf of the Participant in a fiduciary capacity under state law or court supervision.

(b) The Committee may specify at the Date of Grant that part or all of the Units that are (i) to be issued or transferred by the Partnership upon the exercise of Option Rights or Appreciation Rights, upon the termination of the Restriction Period applicable to Restricted Units or upon payment under any grant of Phantom Units or Performance Units or (ii) no longer subject to the substantial risk of forfeiture and restrictions on transfer referred to in Section 6 of this Plan, will be subject to further restrictions on transfer.

14. Withholding Taxes. To the extent that the Partnership is required to withhold federal, state, local or foreign taxes in connection with any payment made or benefit realized by a Participant or other person under this Plan, and the amounts available to the Partnership for such withholding are insufficient, it will be a condition to the receipt of such payment or the realization of such benefit that the Participant or such other person make arrangements satisfactory to the Partnership for payment of the balance of such taxes required to be withheld, which arrangements (in the discretion of the Committee) may include relinquishment of a portion of such benefit. If a Participant’s benefit is to be received in the form of Units, and such Participant fails to make arrangements for the payment of tax, then, unless otherwise determined by the Committee, the Partnership will withhold Units having a value equal to the amount required to be withheld. Notwithstanding the foregoing, when a Participant is required to pay the Partnership an amount required to be withheld under applicable income and employment tax laws, the Participant may elect, unless otherwise determined by the Committee, to satisfy the obligation, in whole or in part, by having withheld, from the Awards required to be delivered to the Participant, Units having a value equal to the amount required to be withheld (except in the case of Restricted Units where an election under Section 83(b) of the Code has been made), or by delivering to the Partnership other Units held by such Participant. The Units used for tax withholding will be valued at an amount equal to the market value of such Units on the date the benefit is to be included in Participant’s income. In no event will the market value of the Units to be withheld and delivered pursuant to this Section to satisfy applicable withholding taxes in connection with the benefit exceed the minimum amount of taxes required to be withheld. Participants will also make such arrangements as the Partnership may require for the payment of any withholding tax obligation that may arise in connection with the disposition of Units acquired upon the exercise of Option Rights.

15. Compliance with Section 409A of the Code.

(a) To the extent applicable, it is intended that this Plan and any grants made hereunder comply with the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the Participants. This

14

Plan and any grants made hereunder will be administered in a manner consistent with this intent. Any reference in this Plan to Section 409A of the Code will also include any regulations or any other formal guidance promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.

(b) Neither a Participant nor any of a Participant’s creditors or beneficiaries will have the right to subject any deferred compensation (within the meaning of Section 409A of the Code) payable under this Plan and grants hereunder to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment. Except as permitted under Section 409A of the Code, any deferred compensation (within the meaning of Section 409A of the Code) payable to a Participant or for a Participant’s benefit under this Plan and grants hereunder may not be reduced by, or offset against, any amount owing by a Participant to the Partnership or any of its Subsidiaries.

(c) If, at the time of a Participant’s separation from service (within the meaning of Section 409A of the Code), (i) the Participant will be a specified employee (within the meaning of Section 409A of the Code and using the identification methodology selected by the Partnership from time to time) and (ii) the Partnership makes a good faith determination that an amount payable hereunder constitutes deferred compensation (within the meaning of Section 409A of the Code) the payment of which is required to be delayed pursuant to the six-month delay rule set forth in Section 409A of the Code in order to avoid taxes or penalties under Section 409A of the Code, then the Partnership will not pay such amount on the otherwise scheduled payment date but will instead pay it, without interest, on the tenth business day of the seventh month after such separation from service.

(d) Notwithstanding any provision of this Plan and grants hereunder to the contrary, in light of the uncertainty with respect to the proper application of Section 409A of the Code, the Partnership reserves the right to make amendments to this Plan and grants hereunder as the Partnership deems necessary or desirable to avoid the imposition of taxes or penalties under Section 409A of the Code. In any case, a Participant will be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on a Participant or for a Participant’s account in connection with this Plan and grants hereunder (including any taxes and penalties under Section 409A of the Code), and neither the Partnership, Company nor any of their Affiliates will have any obligation to indemnify or otherwise hold a Participant harmless from any or all of such taxes or penalties.

16. Amendments.

(a) Except as required by applicable law or the rules of the principal securities exchange on which the Units are traded, the Board may at any time and from time to time amend this Plan in whole or in part.

(b) If permitted by Section 409A of the Code, but subject to the paragraph that follows, including in the case of termination of employment by reason of death, disability or retirement, or in the event of a Change in Control, to the extent a Participant holds an Option Right or Appreciation Right not immediately exercisable in full, or any Restricted Units or Phantom Units as to which the substantial risk of forfeiture or the prohibition or restriction on

15

transfer has not lapsed, or any Cash Incentive Awards or Performance Units which have not been fully earned, or any Other Awards subject to any vesting schedule or transfer restriction, or who holds Units subject to any transfer restriction imposed pursuant to Section 13(b) of this Plan, the Committee may, in its sole discretion, accelerate the time at which such Option Right, Appreciation Right or Other Award may be exercised or the time at which such substantial risk of forfeiture or prohibition or restriction on transfer with respect to a Restricted Unit or a Phantom Unit will lapse or the time when such Restriction Period will end or the time at which such Cash Incentive Awards, Phantom Units or Performance Units will be deemed to have been fully earned or the time when such transfer restriction will terminate or may waive any other limitation or requirement under any such Award.

Except as required by applicable law or the rules of the principal securities exchange on which the Units are traded, the Committee may amend the terms of any Award theretofore granted under this Plan prospectively or retroactively. Subject to Section 11 above, no such amendment will impair the rights of any Participant without his or her consent. The Board may, in its discretion, terminate this Plan at any time. Termination of this Plan will not affect the rights of Participants or their successors under any Awards outstanding hereunder and not exercised in full on the date of termination.

17. Governing Law. This Plan and all grants and Awards and actions taken hereunder will be governed by and construed in accordance with the internal substantive laws of the State of Delaware.

18. Miscellaneous Provisions.

(a) The Partnership will not be required to issue any fractional Units pursuant to this Plan. The Committee may provide for the elimination of fractions or for the settlement of fractions in cash.

(b) This Plan will not confer upon any Participant any right with respect to continuance of employment or other service with the Partnership or any Subsidiary, nor will it interfere in any way with any right the Partnership or any Subsidiary would otherwise have to terminate such Participant’s employment or other service at any time.

(c) No Award under this Plan may be exercised by the holder thereof if such exercise, and the receipt of Units thereunder, would be, in the opinion of counsel selected by the Partnership, contrary to law or the regulations of any duly constituted authority having jurisdiction over this Plan.

(d) Absence on leave approved by a duly constituted officer of the Partnership or any of its Subsidiaries will not be considered interruption or termination of service of any employee for any purposes of this Plan or Awards granted hereunder.

(e) No Participant will have any rights as a Unitholder with respect to any Units subject to Awards granted to him or her under this Plan prior to the date as of which he or she is actually recorded as the holder of such Units upon the records of the Partnership.

16

(f) The Committee may condition the grant of any Award or combination of Awards authorized under this Plan on the surrender or deferral by the Participant of his or her right to receive a cash bonus or other compensation otherwise payable by the Partnership or a Subsidiary to the Participant.

(g) Except with respect to Option Rights and Appreciation Rights, the Committee may permit Participants to elect to defer the issuance of Units or the payment of cash under the Plan pursuant to such rules, procedures or programs as it may establish for purposes of this Plan and which are intended to comply with the requirements of Section 409A of the Code. The Committee also may provide that deferred issuances and settlements include the payment or crediting of DERs or interest on the deferral amounts.

(h) If any provision of this Plan is or becomes invalid or unenforceable in any jurisdiction, or would disqualify this Plan or any Award under any law deemed applicable by the Committee, such provision will be construed or deemed amended or limited in scope to conform to applicable laws or, in the discretion of the Committee, it will be stricken and the remainder of this Plan will remain in full force and effect.

19. Unit-Based Awards in Substitution for Option Rights or Awards Granted by Other Entity. Notwithstanding anything in this Plan to the contrary:

(a) Awards may be granted under this Plan in substitution for or in conversion of, or in connection with equity-based awards held by awardees of an entity engaging in a corporate acquisition or merger transaction with the Partnership or any Subsidiary. Any conversion, substitution or assumption will be effective as of the close of the merger or acquisition, and, to the extent applicable, will be conducted in a manner that complies with Section 409A of the Code. The Awards so granted may reflect the original terms of the awards being assumed or substituted or converted for and need not comply with other specific terms of this Plan, and may account for Units substituted for the securities covered by the original awards and the number of Securities subject to the original awards, as well as any exercise or purchase prices applicable to the original awards, adjusted to account for differences in prices in connection with the transaction.

(b) In the event that an entity acquired by the Partnership or any Subsidiary or with which the Partnership or any Subsidiary merges has securities available under a pre-existing plan previously approved by shareholders/partners and not adopted in contemplation of such acquisition or merger, the securities available for grant pursuant to the terms of such plan (as adjusted, to the extent appropriate, to reflect such acquisition or merger) may be used for awards made after such acquisition or merger under the Plan; provided, however, that Awards using such available securities may not be made after the date awards or grants could have been made under the terms of the pre-existing plan absent the acquisition or merger, and may only be made to individuals who were not employees or Directors of the Partnership or any Subsidiary prior to such acquisition or merger.

(c) Any Units that are issued or transferred by, or that are subject to any Awards that are granted by, or become obligations of, the Partnership under Sections 19(a) or 19(b) above will not reduce the Units available for issuance or transfer under the Plan or

17

otherwise count against the limits contained in Section 3 of the Plan. In addition, no Units that are issued or transferred by, or that are subject to any Awards that are granted by, or become obligations of, the Partnership under Sections 19(a) or 19(b) above will be added to the aggregate Plan limit contained in Section 3 of the Plan.
