                    (i) In connection with the granting of an Option, Unit Appreciation Right, Restricted Unit, Phantom Unit, or Other Unit-Based Award, the number of Units available under this Section 4 for the granting of further Options and Awards shall be reduced by the number of Units in respect of which the Option or Award is granted or denominated.

                    (ii) In connection with the granting of a Distribution Equivalent Right, the number of Units available under this Section 4 shall not be reduced; provided, however, that if Units are issued in settlement of a Distribution Equivalent Right, the number of Units available for the granting of further Options and Awards under this Section 4 shall be reduced by the number of Units so issued.

               (b) Notwithstanding Section 4.2(a), in the event that an Award is granted that, pursuant to the terms of the Agreement, cannot be settled in Units, the aggregate number of Units that may be made the subject of Awards or Options granted under the Plan shall not be reduced. Whenever any outstanding Option or Award or portion thereof expires, is canceled, is forfeited, is settled in cash or is otherwise terminated for any reason without having been exercised or payment having been made in respect of the entire Option or Award, the number of Units previously allocable to the expired, forfeited canceled, settled or otherwise terminated portion of the Option or Award shall again be available for the granting of Options or Awards under the Plan.

          5.3 Maximum Duration. Options granted hereunder shall be for such term as the Committee shall determine; provided, that an Option shall not be exercisable after the expiration of ten (10) years from the date it is granted; provided, further, however, that unless the Committee provides otherwise, an Option may, upon the death of the Participant prior to the expiration of the Option, be exercised for up to one (1) year following the date of the Participant’s death, even if such period extends beyond ten (10) years from the date the Option is granted. The Committee may, subsequent to the granting of any Option, extend the term thereof, but in no event shall the term as so extended exceed the maximum term provided for in the preceding sentence.

          5.4 Vesting. The Committee shall determine the time or times at which an Option shall become vested and exercisable.

Except as otherwise provided in this Section 5.5, no Option shall be transferable by the Participant otherwise than by will or by the laws of descent and distribution, and an Option shall be exercisable during the lifetime of such Participant only by the Participant or his or her guardian or legal representative. The Committee may set forth in the Agreement evidencing an Option at the time of grant or thereafter, that the Option, or a portion thereof, may be transferred to any third party, including but not limited to, members of the Participant’s immediate family, to trusts solely for the benefit of such immediate family members and to partnerships in which such family members and/or trusts are the only partners. In addition, for purposes of the Plan, unless otherwise determined by the Committee at the time of grant or thereafter, a transferee of an Option pursuant to this Section 5.5 shall be deemed to be the Participant; provided that the rights of any such transferee thereafter shall be nontransferable except that such transferee, where applicable under the terms of the transfer by the Participant, shall have the right previously held by the Participant to designate a Beneficiary. For this purpose, immediate family means the Participant’s spouse, parents, children, stepchildren and grandchildren and the spouses of such parents, children, stepchildren and grandchildren. The terms of an Option shall be final, binding and conclusive upon the beneficiaries, executors, administrators, heirs and successors of the Participant. Notwithstanding Section 18.2, or the terms of any Agreement, neither the Partnership nor any of its Subsidiaries or Parents shall withhold any amount attributable to the Participant’s tax liability from any payment of cash or Units to a transferee or transferee’s Beneficiary under this Section 5.5, but may require the payment of an amount equal to the Partnership’s or any of its Subsidiaries’ or Parents’ withholding tax obligation as a condition to exercise or as a condition to the release of cash or Units upon exercise or upon transfer of the option.

          5.6 Method of Exercise. The exercise of an Option shall be made only by giving written notice delivered in person or by mail to the person designated by the Partnership, specifying the number of Units to be exercised and, to the extent applicable, accompanied by payment therefor and otherwise in accordance with the Agreement pursuant to which the Option was granted. The exercise price for any Units purchased pursuant to the exercise of an Option shall be paid in any or any combination of the following forms: (a) cash or its equivalent (e.g., a check) or (b) if permitted by the Committee, the transfer, either actually or by attestation, to the Partnership of Units that have been held by the Participant for at least six (6) months (or such lesser period as may be permitted by the Committee) prior to the exercise of the Option, such transfer to be upon such terms and conditions as determined by the Committee or (c) in the form of other property as determined by the Committee. In addition, Options may be exercised through a registered broker-dealer pursuant to such cashless exercise procedures that are, from time to time, deemed acceptable by the Committee. Any Units transferred to the Partnership as payment of the exercise price under an Option shall be valued at their Fair Market Value on the last business day preceding the date of exercise of such Option. If requested by the Committee, the Participant shall deliver the Agreement evidencing the Option to the Partnership, which shall endorse thereon a notation of such exercise and return such Agreement to the Participant. No fractional Units (or cash in lieu thereof) shall be issued upon exercise of an Option and the number of Units that may be purchased upon exercise shall be rounded to the nearest number of whole Units.

          5.7 Rights of Participants. No Participant shall be deemed for any purpose to be the owner of any Units subject to any Option unless and until (a) the Option shall have been exercised pursuant to the terms thereof, (b) the Partnership shall have issued and delivered Units (whether or not certificated) to the Participant, a securities broker acting on behalf of the Participant or such other nominee of the Participant, and (c) the Participant’s name, or the name of his or her broker or other nominee, shall have been entered as a unitholder of record on the books of the Partnership.

Participant’s death even if such period extends beyond ten (10) years from the date the Unit Appreciation Right is granted.

          6.3 Amount Payable. Upon exercise of a Unit Appreciation Right, the Grantee shall be entitled to receive an amount determined by multiplying (i) the excess of the Fair Market Value of a Unit on the last business day preceding the date of exercise of such Unit Appreciation Right over the Fair Market Value of a Unit on the date the Unit Appreciation Right was granted, by (ii) the number of Units as to which the Unit Appreciation Right is being exercised. Notwithstanding the foregoing, the Committee may limit in any manner the amount payable with respect to any Unit Appreciation Right by including such a limit in the Agreement evidencing the Unit Appreciation Right at the time it is granted.

(i) Except as otherwise provided in this Section 6.4, no Unit Appreciation Right shall be transferable by the Participant otherwise than by will or the laws of descent and distribution, and a Unit Appreciation Right shall be exercisable during the lifetime of such Participant only by the Participant or his or her guardian or legal representative.

In addition, for purposes of the Plan, unless otherwise determined by the Committee at the time of grant or thereafter, a transferee of a Unit Appreciation Right pursuant to this Section 6.4 shall be deemed to be the Participant; provided that the rights of any such transferee thereafter shall be nontransferable except that such transferee, where applicable under the terms of the transfer by the Participant, shall have the right previously held by the Participant to designate a Beneficiary. For this purpose, immediate family means the Participant’s spouse, parents, children, stepchildren and grandchildren and the spouses of such parents, children, stepchildren and grandchildren. Notwithstanding Section 18.2, or the terms of any Agreement, neither the Partnership nor any of its Subsidiaries or Parents shall withhold any amount attributable to the Participant’s tax liability from any payment of cash or Units to a transferee or transferee’s Beneficiary under this Section 6.4, but may require the payment of an amount equal to the Partnership’s or any of its Subsidiaries’ or Parents’ withholding tax obligation as a condition to exercise or as a condition to the release of cash or Units upon exercise or upon transfer of the Unit Appreciation Right.

     7. Distribution Equivalent Rights.

          The Committee may in its discretion, grant Distribution Equivalent Rights either in tandem with an Option or Award or as a separate Award, to Eligible Individuals in accordance with the Plan. The terms and conditions applicable to each Distribution Equivalent Right shall be specified in the Agreement under which the Distribution Equivalent Right is granted. Amounts payable in respect of Distribution Equivalent Rights may be payable currently or, if applicable, deferred until the lapsing of restrictions on such Distribution Equivalent Rights or until the vesting, exercise, payment, settlement or other lapse of restrictions on the Option or Award to which the Distribution Equivalent Rights relate; provided, that Distribution Equivalent Rights may not contain payment or other terms that could adversely affect the Option or Award to which it relates under Section 409A of the Code or otherwise. In the event that the amount payable in respect of Distribution Equivalent Rights are to be deferred, the Committee shall determine whether such amounts are to be held in cash or reinvested in Units or deemed (notionally) to be reinvested in Units. If amounts payable in respect of Distribution Equivalent Rights are to be held in cash, there may be credited at the end of each year (or portion thereof) interest on the amount of the account at the beginning of the year at a rate per annum as the Committee, in its discretion, may determine.

               (e) Delivery of Units. Upon the lapse of the restrictions on Restricted Units, the Committee shall cause a unit certificate or other evidence of issuance of Units to be delivered to the Participant with respect to such Restricted Units, free of all restrictions hereunder.

          8.2 Phantom Unit Awards. The Committee may grant to Eligible Individuals Phantom Units, which shall be evidenced by an Agreement. Each such Agreement shall contain

such restrictions, terms and conditions as the Committee may, in its discretion, determine. Phantom Units shall be subject to the terms and provisions set forth below in this Section 8.2.

               (a) Payment of Awards. Each Phantom Unit shall represent the right of the Participant to receive a payment upon vesting of the Phantom Unit or on any later date specified by the Committee equal to the Fair Market Value of a Unit as of the date the Phantom Unit was granted, the vesting date or such other date as determined by the Committee at the time the Phantom Unit was granted. The Committee may, at the time a Phantom Unit is granted, provide a limitation on the amount payable in respect of each Phantom Unit. The Committee may provide for the settlement of Phantom Units in cash or with Units having a Fair Market Value equal to the payment to which the Participant has become entitled.

               (b) Effect of Change in Control. The effect of a Change in Control on an Award of Phantom Units shall be set forth in the applicable Agreement.

     9. Other Unit-Based Awards.

          The Committee may grant Other Unit-Based Awards to any Eligible Individual on such terms and conditions as the Committee may determine in its sole discretion. Other Unit-Based Awards may be made as additional compensation for services rendered by the Eligible Individual or may be in lieu of cash or other compensation to which the Eligible Individual is entitled from the Partnership.

     10. Effect of a Termination of Employment.

          The Agreement evidencing the grant of each Option and each Award shall set forth the terms and conditions applicable to such Option or Award upon (a) a termination or change in the status of the employment of the Participant by the Partnership, a Subsidiary or Parent of the Partnership, or a Division (including a termination or change by reason of the sale of any Subsidiary or Parent of the Partnership, or a Division), or (b) in the case of a Director, the cessation of the Director’s service on the Board, which shall be as the Committee may, in its discretion, determine at the time the Option or Award is granted or thereafter.

     11. Adjustment Upon Changes in Capitalization.

          11.1 In the event of a Change in Capitalization, the Committee shall conclusively determine the appropriate adjustments, if any, to (a) the maximum number and class of Units or other stock or securities with respect to which Options or Awards may be granted under the Plan and (b) the number and class of Units or other stock or securities, cash or other property which are subject to outstanding Options or Awards granted under the Plan and the exercise price therefore, if applicable.

          11.2 If, by reason of a Change in Capitalization, a Participant shall be entitled to, or shall be entitled to exercise an Option with respect to, new, additional or different units or securities of the Partnership or any other corporation, such new, additional or different securities shall thereupon be subject to all of the conditions, restrictions and performance criteria which

were applicable to the Units subject to the Award or Option, as the case may be, prior to such Change in Capitalization.

     12. Effect of Certain Transactions.

          Subject to the terms of an Agreement, following (a) the liquidation or dissolution of the Partnership or (b) a merger or consolidation of the Partnership (a “Transaction”), either (i) each outstanding Option or Award shall be treated as provided for in the agreement entered into in connection with the Transaction or (ii) if not so provided in such agreement, each Optionee and Grantee shall be entitled to receive in respect of each Unit subject to any outstanding Options or Awards, as the case may be, upon exercise of any Option or payment or transfer in respect of any Award, the same number and kind of stock, securities, cash, property or other consideration that each holder of a Unit was entitled to receive in the Transaction in respect of a Unit; provided, however, that such stock, securities, cash, property, or other consideration shall remain subject to all of the conditions, restrictions and performance criteria which were applicable to the Options and Awards prior to such Transaction. Without limiting the generality of the foregoing, the treatment of outstanding Options and Awards pursuant to clause (i) of this Section 12 in connection with a Transaction may include the cancellation of outstanding Options and Awards upon consummation of the Transaction provided either (x) the holders of affected Options have been given a period of at least fifteen (15) days prior to the date of the consummation of the Transaction to exercise the Options (whether of not they were otherwise exercisable) or (y) the holders of affected Options and Awards are paid (in cash or cash equivalents) the following amounts: (A) in respect of each Unit underlying Options being cancelled, an amount equal to the excess, if any, of the per unit price paid or distributed to stockholders in the transaction (the value of any non-cash consideration to be determined by the Committee in its sole discretion) over the exercise price of the Option; and (B) in respect of each Unit covered by Awards being cancelled, an amount equal to the per unit price paid or distributed to stockholders in the transaction (the value of any non-cash consideration to be determined by the Committee in its sole discretion). For avoidance of doubt, the cancellation of Options and Awards pursuant to clause (y) of the preceding sentence may be effected notwithstanding anything to the contrary contained in this Plan or any Agreement, and if the amount determined pursuant to clause (y) of the preceding sentence is zero or less, the affected Option or Award may be cancelled without any payment therefor. The treatment of any Option or Award as provided in this Section 12 shall be conclusively presumed to be appropriate for purposes of Section 11.

     13. Interpretation.

          13.1 Section 16 Compliance. The Plan is intended to comply with Rule 16b-3 promulgated under the Exchange Act and the Committee shall interpret and administer the provisions of the Plan or any Agreement in a manner consistent therewith. Any provisions inconsistent with such Rule shall be inoperative and shall not affect the validity of the Plan.

          13.2 Compliance With Section 409A. All Options and Awards granted under the Plan are intended either not to be subject to Section 409A of the Code or, if subject to Section

409A of the Code, 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 Committee may amend the Plan or any Option or Award granted hereunder in any manner, or take any other action that it determines, in its sole discretion, is necessary, appropriate or advisable (including replacing any Option or Award) to cause the Plan or any Option or Award granted hereunder to comply with Section 409A and any guidance issued thereunder or to not be subject to Section 409A. Any such action, once taken, shall be deemed to be effective from the earliest date necessary to avoid a violation of Section 409A and shall be final, binding and conclusive on all Eligible Individuals and other individuals having or claiming any right or interest under the Plan.

     14. Termination and Amendment of the Plan or Modification of Options and Awards.

          14.1 Plan Amendment or Termination. The Board may at any time terminate the Plan and the Board may at any time and from time to time amend, modify or suspend the Plan; provided, however, that:

               (a) no such amendment, modification, suspension or termination shall impair or adversely alter any Options or Awards theretofore granted under the Plan, except with the consent of the Participant, nor shall any amendment, modification, suspension or termination deprive any Participant of any Units which he or she may have acquired through or as a result of the Plan; and

               (b) to the extent necessary under any applicable law, regulation or exchange requirement, no other amendment shall be effective unless approved by the unitholders of the Partnership in accordance with applicable law, regulation or exchange requirement.

          14.2 Modification of Options and Awards. No modification of an Option or Award shall adversely alter or impair any rights or obligations under the Option or Award without the consent of the Participant.

     15. Non-Exclusivity of the Plan.

          The adoption of the Plan by the Board shall not be construed as amending, modifying or rescinding any previously approved incentive arrangement or as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of stock options otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases.

     16. Limitation of Liability.

          As illustrative of the limitations of liability of the Partnership, but not intended to be exhaustive thereof, nothing in the Plan shall be construed to:

               (a) give any person any right to be granted an Option or Award other than at the sole discretion of the Committee;

               (b) give any person any rights whatsoever with respect to Units except as specifically provided in the Plan;

               (c) limit in any way the right of the Partnership or any of its Subsidiaries or Parents to terminate the employment of any person at any time; or

               (d) be evidence of any agreement or understanding, express or implied, that the Partnership will employ any person at any particular rate of compensation or for any particular period of time.

     17. Regulations and Other Approvals; Governing Law.

          17.1 Except as to matters of federal law, the Plan and the rights of all persons claiming hereunder shall be construed and determined in accordance with the laws of the State of Delaware without giving effect to conflicts of laws principles thereof.

          17.2 The obligation of the Partnership to sell or deliver Units with respect to Options and Awards granted under the Plan shall be subject to all applicable laws, rules and regulations, including all applicable federal and state securities laws, and the obtaining of all such approvals by governmental agencies as may be deemed necessary or appropriate by the Committee.

          17.3 The Board may make such changes as may be necessary or appropriate to comply with the rules and regulations of any government authority.

          17.4 Each grant of an Option and Award and the issuance of Units or other settlement of the Option or Award is subject to the compliance with all applicable federal, state or foreign law. Further, if at any time the Committee determines, in its discretion, that the listing, registration or qualification of Units issuable pursuant to the Plan is required by any securities exchange or under any federal, state or foreign law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the grant of an Option or Award or the issuance of Units, no Options or Awards shall be or shall be deemed to be granted or payment made or Units issued, in whole or in part, unless listing, registration, qualification, consent or approval has been effected or obtained free of any conditions that are not acceptable to the Committee. Any person exercising an Option or receiving Units in connection with any other Award shall make such representations and agreements and furnish such information as the Board or Committee may request to assure compliance with the foregoing or any other applicable legal requirements.

          17.5 Notwithstanding anything contained in the Plan or any Agreement to the contrary, in the event that the disposition of Units acquired pursuant to the Plan is not covered by a then current registration statement under the Securities Act of 1933, as amended (the “Securities Act”), and is not otherwise exempt from such registration, such Units shall be

restricted against transfer to the extent required by the Securities Act and Rule 144 or other regulations promulgated thereunder. The Committee may require any individual receiving Units pursuant to an Option or Award granted under the Plan, as a condition precedent to receipt of such Units, to represent and warrant to the Partnership in writing that the Units acquired by such individual are acquired without a view to any distribution thereof and will not be sold or transferred other than pursuant to an effective registration thereof under the Securities Act or pursuant to an exemption applicable under the Securities Act or the rules and regulations promulgated thereunder. The certificates evidencing any of such Units shall be appropriately amended or have an appropriate legend placed thereon to reflect their status as restricted securities as aforesaid.

     18. Miscellaneous.

          18.1 Multiple Agreements. The terms of each Option or Award may differ from other Options or Awards granted under the Plan at the same time, or at some other time. The Committee may also grant more than one Option or Award to a given Eligible Individual during the term of the Plan, either in addition to, or subject to Section 3.6, in substitution for, one or more Options or Awards previously granted to that Eligible Individual.

          18.2 Withholding of Taxes.

               (a) The Partnership and its Subsidiaries and Parents may withhold from any payment of cash or Units to a Participant or other person under the Plan an amount sufficient to cover any withholding taxes which may become required with respect to such payment or shall take any other action as it deems necessary to satisfy any income or other tax withholding requirements as a result of the grant or exercise of any Award under the Plan. The Partnership and its Subsidiaries and Parents shall have the right to require the payment of any such taxes and require that any person furnish information deemed necessary by the Partnership or any Subsidiary or Parent of the Partnership to meet any tax reporting obligation as a condition to exercise or before making any payment pursuant to an Award or Option. If specified in an Agreement at the time of grant or otherwise approved by the Committee, a Participant may, in satisfaction of his or her obligation to pay withholding taxes in connection with the exercise, vesting or other settlement of an Option or Award, elect to (i) make a cash payment to the Partnership, (ii) have withheld a portion of the Units then issuable to him or her, or (iii) surrender Units owned by the Participant prior to the exercise, vesting or other settlement of an Option or Award, in each case having an aggregate Fair Market Value equal to the withholding taxes.

          18.3 Plan Unfunded. The Plan shall be unfunded. Except for reserving a sufficient number of authorized Units to the extent required by law to meet the requirements of the Plan, the Partnership shall not be required to establish any special or separate fund or to make any other segregation of assets to assure payment of any Award or Option granted under the Plan.

          18.4 Beneficiary Designation. Each Participant may, from time to time, name one or more individuals (each, a “Beneficiary”) to whom any benefit under the Plan is to be paid in case of the Participant’s death before he or she receives any or all of such benefit. Each such

designation shall revoke all prior designations by the same Participant, shall be in a form prescribed by the Partnership, and will be effective only when filed by the Participant in writing with the Partnership during the Participant’s lifetime. In the absence of any such designation, benefits remaining unpaid at the Participant’s death shall be paid to the Participant’s estate.

          18.5 Effective Date/Term. The effective date of the Plan shall be the date of its approval by the Board (the “Effective Date”). The Plan shall terminate on the Termination Date. No Option or Award shall be granted after the Termination Date. The applicable terms of the Plan, and any terms and conditions applicable to Options and Awards granted prior to the Termination Date shall survive the termination of the Plan and continue to apply to such Options and Awards.
