For purposes of this definition, “long-term” generally refers to a period exceeding 12 months.

“ Additional Book Basis ” means the portion of any remaining Carrying Value of an Adjusted Property that is attributable to positive adjustments made to such Carrying Value as a result of Book-Up Events. For purposes of determining the extent that Carrying Value constitutes Additional Book Basis:

(a)                                  Any negative adjustment made to the Carrying Value of an Adjusted Property as a result of either a Book-Down Event or a Book-Up Event shall first be deemed to offset or decrease that portion of the Carrying Value of such Adjusted Property that is attributable to any prior positive adjustments made thereto pursuant to a Book-Up Event or Book-Down Event.

(b)                                  If Carrying Value that constitutes Additional Book Basis is reduced as a result of a Book-Down Event and the Carrying Value of other property is increased as a result of such Book-Down Event, an allocable portion of any such increase in Carrying Value shall be treated as Additional Book Basis; provided, that the amount treated as Additional Book Basis pursuant hereto as a result of such Book-Down Event shall not exceed the amount by which the Aggregate Remaining Net Positive Adjustments after such Book-Down Event exceeds the remaining Additional Book Basis attributable to all of the Partnership’s Adjusted

Property after such Book-Down Event (determined without regard to the application of this clause (b) to such Book-Down Event).

“ Additional Book Basis Derivative Items ” means any Book Basis Derivative Items that are computed with reference to Additional Book Basis. To the extent that the Additional Book Basis attributable to all of the Partnership’s Adjusted Property as of the beginning of any taxable period exceeds the Aggregate Remaining Net Positive Adjustments as of the beginning of such period (the “ Excess Additional Book Basis ”), the Additional Book Basis Derivative Items for such period shall be reduced by the amount that bears the same ratio to the amount of Additional Book Basis Derivative Items determined without regard to this sentence as the Excess Additional Book Basis bears to the Additional Book Basis as of the beginning of such period.

45

Section 4.9                              Eligibility Certificates; Ineligible Holders .

(a)                            If at any time the General Partner determines, with the advice of counsel, that

(i)                                      the Partnership’s status other than as an association taxable as a corporation for U.S. federal income tax purposes or the failure of the Partnership otherwise to be subject to an entity-level tax for U.S. federal, state or local income tax purposes, coupled with the tax status (or lack of proof of the federal income tax status) of one or more Limited Partners, has or will reasonably likely have a material adverse effect on the maximum applicable rate that can be charged to customers by Subsidiaries of the Partnership (a “ Rate Eligibility Trigger ”), or

(ii)                                   any Group Member is subject to any federal, state or local law or regulation that would create a substantial risk of cancellation or forfeiture of any property in which the Group Member has an interest based on the nationality, citizenship or other related status of a Limited Partner (a “ Citizenship Eligibility Trigger ”);

then, the General Partner may adopt such amendments to this Agreement as it determines to be necessary or advisable to (x) in the case of a Rate Eligibility Trigger, obtain such proof of the federal income tax status of the Limited Partners and, to the extent relevant, their beneficial owners, as the General Partner determines to be necessary to establish those Limited Partners whose federal income tax status does not or would not have a material adverse effect on the maximum applicable rate that can be charged to customers by Subsidiaries of the Partnership or (y) in the case of a Citizenship Eligibility Trigger, obtain such proof of the nationality, citizenship or other related status (or, if the General Partner is a nominee holding for the account of another Person, the nationality, citizenship or other related status of such Person) of the Limited Partner as the General Partner determines to be necessary to establish those Limited Partners whose status as a Limited Partner does not or would not subject any Group Member to a significant risk of cancellation or forfeiture of any of its properties or interests therein.

(b)                            Such amendments may include provisions requiring all Limited Partners to certify as to their (and their beneficial owners’) status as Eligible Holders upon demand and on a regular basis, as determined by the General Partner, and may require transferees of Units to so certify prior to being admitted to the Partnership as a Limited Partner (any such required certificate, an “ Eligibility Certificate ”).

(c)                             Such amendments may provide that any Limited Partner who fails to furnish to the General Partner within a reasonable period requested proof of its (and its beneficial owners’) status as an Eligible Holder or if upon receipt of such Eligibility Certificate or other requested information the General Partner determines that a Limited Partner is not an Eligible Holder (such a Limited Partner an “ Ineligible Holder ”), the Limited Partner Interests owned by such Limited Partner shall be subject to redemption in accordance with the provisions of Section 4.10 . In addition, the General Partner shall be substituted for all Limited Partners that are Ineligible Holder as the Limited Partner in respect of the Ineligible Holder’s Limited Partner Interests.

(d)                            The General Partner shall, in exercising voting rights in respect of Limited Partner Interests held by it on behalf of Ineligible Holders, distribute the votes in the same ratios as the votes of Limited Partners (including the General Partner and its Affiliates) in respect of Limited

46

Partner Interests other than those of Ineligible Holders are cast, either for, against or abstaining as to the matter.

(e)                             Upon dissolution of the Partnership, an Ineligible Holder shall have no right to receive a distribution in kind pursuant to Section 12.4 but shall be entitled to the cash equivalent thereof, and the Partnership shall provide cash in exchange for an assignment of the Ineligible Holder’s share of any distribution in kind. Such payment and assignment shall be treated for Partnership purposes as a purchase by the Partnership from the Ineligible Holder of his Limited Partner Interest (representing his right to receive his share of such distribution in kind).

(f)                              At any time after an Ineligible Holder can and does certify that he has become an Eligible Holder, an Ineligible Holder may, upon application to the General Partner, request that with respect to any Limited Partner Interests of such Ineligible Holder not redeemed pursuant to Section 4.10 , such Ineligible Holder be admitted as a Limited Partner, and upon approval of the General Partner, such Ineligible Holder shall be admitted as a Limited Partner and shall no longer constitute an Ineligible Holder and the General Partner shall cease to be deemed to be the Limited Partner in respect of the Ineligible Holder’s Limited Partner Interests.

Section 4.10                       Redemption of Partnership Interests of Ineligible Holders .

(a)                            If at any time a Limited Partner fails to furnish an Eligibility Certification or other information requested within a reasonable period of time specified in amendments adopted pursuant to Section 4.9 , or if upon receipt of such Eligibility Certification or other information the General Partner determines, with the advice of counsel, that a Limited Partner is an Ineligible Holder, the Partnership may, unless the Limited Partner establishes to the satisfaction of the General Partner that such Limited Partner is not an Ineligible Holder or has transferred his Limited Partner Interests to a Person who is an Eligible Holder and who furnishes an Eligibility Certification to the General Partner prior to the date fixed for redemption as provided below, redeem the Limited Partner Interest of such Limited Partner as follows:

(i)                                      The General Partner shall, not later than the 30th day before the date fixed for redemption, give notice of redemption to the Limited Partner, at his last address designated on the records of the Partnership or the Transfer Agent, by registered or certified mail, postage prepaid. The notice shall be deemed to have been given when so mailed. The notice shall specify the Redeemable Interests, the date fixed for redemption, the place of payment, that payment of the redemption price will be made upon redemption of the Redeemable Interests (or, if later in the case of Redeemable Interests evidenced by Certificates, upon surrender of the Certificate evidencing the Redeemable Interests, and that on and after the date fixed for redemption no further allocations or distributions to which the Limited Partner would otherwise be entitled in respect of the Redeemable Interests will accrue or be made).

(ii)                                   The aggregate redemption price for Redeemable Interests shall be an amount equal to the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Limited Partner Interests of the class to be so redeemed multiplied by the number of Limited Partner Interests of each such class included among the Redeemable Interests. The redemption price shall be paid, as determined by the

47

General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the rate of 5% annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date.

(iii)                                The Limited Partner or his duly authorized representative shall be entitled to receive the payment for the Redeemable Interests at the place of payment specified in the notice of redemption on the redemption date (or, if later in the case of Redeemable Interests evidenced by Certificates, upon surrender by or on behalf of the Limited Partner or Transferee at the place specified in the notice of redemption, of the Certificate evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an assignment duly executed in blank).

(iv)                               After the redemption date, Redeemable Interests shall no longer constitute issued and Outstanding Limited Partner Interests.

(b)                            The provisions of this Section 4.10 shall also be applicable to Limited Partner Interests held by a Limited Partner as nominee of a Person determined to be other than an Eligible Holder.

(c)                             Nothing in this Section 4.10 shall prevent the recipient of a notice of redemption from transferring his Limited Partner Interest before the redemption date if such transfer is otherwise permitted under this Agreement. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided the transferee of such Limited Partner Interest certifies to the satisfaction of the General Partner that he is an Eligible Holder. If the transferee fails to make such certification, such redemption shall be effected from the transferee on the original redemption date.

Section 4.11                       Restrictions on Transfer of Class A Preferred Units .

(a)                            [Reserved].

(b)                            From and after the first anniversary of the Initial Class A Closing Date, each Purchaser may transfer any Class A Preferred Units held by it to any other Person or Persons, except for any transfers to any Person or group (as defined by Section 13(d) of the Securities Exchange Act) that, after giving effect to such transfer, would own more than 15% of the Outstanding Common Units, including the number of Common Units into which such Class A Preferred Units to be transferred to such Person or group are then convertible; provided , however , that the foregoing restriction shall not apply to any transfer of Class A Preferred Units to (i) any investment bank or similar institution that assists in the brokering or marketing of the Class A Preferred Units on behalf of any Purchaser or (ii) any Affiliate of such Purchaser, provided , that, in the case of this clause (ii), subsequent transferees (including such Affiliates) remain subject to the restriction.

(c)                             Notwithstanding anything to the contrary contained herein, a Purchaser shall at all times from and after the Initial Class A Closing Date be permitted to transfer any Class A Preferred Units held by such Purchaser to any Person that is an Affiliate of such Purchaser or another Purchaser or its Affiliates (such Person, a “ Permitted Affiliate ”).

48

(d)                            Notwithstanding anything to the contrary contained herein, no Purchaser shall transfer any Class A Preferred Units to any Person that is a Competitor; provided , however , that the foregoing restriction shall not apply to any transfer of Class A Preferred Units on any National Securities Exchange on which the Class A Preferred Units are then-listed or admitted for trading; provided , further , that there shall be no obligation to list or admit the Class A Preferred Units for trading on any National Securities Exchange.

(e)                             This Section 4.11 sets forth all restrictions on transfer applicable to Class A Preferred Units.

ARTICLE V

CAPITAL CONTRIBUTIONS AND ISSUANCE OF PARTNERSHIP INTERESTS

Section 5.1                              Contributions by the General Partner and the Initial Limited Partners .  In connection with the execution of and as set forth in the First Amended and Restated Partnership Agreement, (i) the General Partner made a capital contribution to the Partnership in exchange for a continuation of its General Partner Interest equal to a 0.1% Percentage Interest and the Incentive Distribution Rights and (ii) the Initial Limited Partners made capital contributions to the Partnership in exchange for an aggregate Limited Partnership Interest equal to a 99.9% Percentage Interest.

Section 5.2                              Maintenance of General Partner’s Percentage Interest .  Upon the issuance of any additional Limited Partner Interests by the Partnership (other than any Common Units issued pursuant to Section 5.11 ), the General Partner may, in order to maintain its Percentage Interest, make additional Capital Contributions in an amount equal to the product obtained by multiplying (i) the quotient determined by dividing (A) the General Partner’s Percentage Interest by (B) 100 less the General Partner’s Percentage Interest times (ii) the amount contributed to the Partnership by the Limited Partners in exchange for such additional Limited Partner Interests. Except as set forth in Section 12.8 , the General Partner shall not be obligated to make any additional Capital Contributions to the Partnership.

Section 5.3                              Contributions by Limited Partners .  No Limited Partner will be required to make any additional Capital Contribution to the Partnership pursuant to this Agreement.

Section 5.4                              Interest and Withdrawal .  No interest shall be paid by the Partnership on Capital Contributions. No Partner shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon liquidation of the Partnership may be considered as such by law and then only to the extent provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Partner shall have priority over any other Partner either as to the return of Capital Contributions or as to profits, losses or distributions. Any such return shall be a compromise to which all Partners agree within the meaning of Section 17-502(b) of the Delaware Act.

Section 5.5                              Capital Accounts .

(a)                            The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee in any case in which the nominee has furnished the

49

identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner in its sole discretion) owning a Partnership Interest a separate Capital Account with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). Such Capital Account shall be increased by (i) the amount of all Capital Contributions made to the Partnership with respect to such Partnership Interest pursuant to this Agreement and (ii) all items of Partnership income and gain (including, without limitation, income and gain exempt from tax) computed in accordance with Section 5.5(b)  and allocated with respect to such Partnership Interest pursuant to Section 6.1 , and decreased by (x) the amount of cash or Net Agreed Value of all distributions of cash or property made with respect to such Partnership Interest pursuant to this Agreement; provided that the Capital Account attributable to a Class B Preferred Unit or a Class C Preferred Unit, as applicable, shall not be reduced by the amount of Class B Preferred Unit Distributions or Class C Preferred Unit Distributions, as applicable, made with respect to such Class B Preferred Unit or Class C Preferred Unit, as applicable; and (y) all items of Partnership deduction and loss computed in accordance with Section 5.5(b)  and allocated with respect to such Partnership Interest pursuant to Section 6.1 . The initial Capital Account with respect to the Class A Preferred Units and the Deemed Warrant Units shall be determined pursuant to the Class A Unit Purchase Agreement. The initial Capital Account attributable to a Class B Preferred Unit shall be the Class B Stated Liquidation Preference, irrespective of the amount paid by the holder of such Class B Preferred Unit for such Unit. The initial Capital Account attributable to a Class C Preferred Unit shall be the Class C Stated Liquidation Preference, irrespective of the amount paid by the holder of such Class C Preferred Unit for such Unit. In connection with the foregoing, the Partnership shall adopt the methodology set forth in the noncompensatory option regulations under Treasury Regulation Sections 1.704-1 and 1.721-2 with respect to the issuance and conversion of Class A Preferred Units, Class B Preferred Units and Class C Preferred Units, unless otherwise required by applicable law.

(b)                            For purposes of computing the amount of any item of income, gain, loss or deduction that is to be allocated pursuant to Article VI and is to be reflected in the Partners’ Capital Accounts, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for federal income tax purposes (including any method of depreciation, cost recovery or amortization used for that purpose), provided, that:

(i)                                      Solely for purposes of this Section 5.5 , the Partnership shall be treated as owning directly its proportionate share (as determined by the General Partner based upon the provisions of the applicable Group Member Agreement) of all property owned by (x) any other Group Member that is classified as a partnership for federal income tax purposes and (y) any other partnership, limited liability company, unincorporated business or other entity classified as a partnership for federal income tax purposes of which a Group Member is, directly or indirectly, a partner, member or other equity holder.

(ii)                                   All fees and other expenses incurred by the Partnership to promote the sale of (or to sell) a Partnership Interest that can neither be deducted nor amortized under Section 709 of the Code, if any, shall, for purposes of Capital Account maintenance, be

50

treated as an item of deduction at the time such fees and other expenses are incurred and shall be allocated among the Partners pursuant to Section 6.1 .

(iii)                                Except as otherwise provided in Treasury Regulation Section 1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss and deduction shall be made without regard to any election under Section 754 of the Code that may be made by the Partnership and, as to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for federal income tax purposes. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss.

(iv)                               Any income, gain or loss attributable to the taxable disposition of any Partnership property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the Partnership’s Carrying Value with respect to such property as of such date.

(v)                                  In accordance with the requirements of Section 704(b) of the Code, any deductions for depreciation, cost recovery or amortization attributable to any Contributed Property shall be determined as if the adjusted basis of such property on the date it was acquired by the Partnership were equal to the Agreed Value of such property. Upon an adjustment pursuant to Section 5.5(d)  to the Carrying Value of any Partnership property subject to depreciation, cost recovery or amortization, any further deductions for such depreciation, cost recovery or amortization attributable to such property shall be determined under the rules prescribed by Treasury Regulation Section 1.704-3(d)(2) as if the adjusted basis of such property were equal to the Carrying Value of such property immediately following such adjustment.

(vi)                               The Gross Liability Value of each Liability of the Partnership described in Treasury Regulation Section 1.752-7(b)(3)(i) shall be adjusted at such times as provided in this Agreement for an adjustment to Carrying Values. The amount of any such adjustment shall be treated for purposes hereof as an item of loss (if the adjustment increases the Carrying Value of such Liability of the Partnership) or an item of gain (if the adjustment decreases the Carrying Value of such Liability of the Partnership).

(c)                                   (i)  A transferee of a Partnership Interest shall succeed to a pro rata portion of the Capital Account of the transferor relating to the Partnership Interest so transferred.

(ii)                                   Subject to Section 6.7(c) , immediately prior to the transfer of a converted Subordinated Unit by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this subparagraph 5.5(c)(ii) apply), the Capital Account maintained for such Person with respect to its converted Subordinated Units will (A) first, be allocated to the converted Subordinated Units to be transferred in an amount equal to the product of (x) the number of such converted Subordinated Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any remaining

51

balance in such Capital Account will be retained by the transferor, regardless of whether it has retained converted Subordinated Units. Following any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained converted Subordinated Units, if any, will have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee’s Capital Account established with respect to the transferred converted Subordinated Units will have a balance equal to the amount allocated under clause (A) hereinabove.

(iii)                                Subject to Section 6.11(b) , immediately prior to the transfer of a Deemed Warrant Unit that has been exercised for a Common Unit by a holder thereof (other than a transfer to an Affiliate of the assignor unless the General Partner elects to have this Section 5.5(c)(iii)  apply), the Capital Account maintained for such Person with respect to its Deemed Warrant Units or Common Units granted upon exercise of the Deemed Warrant Units will (A) first, be allocated to the Deemed Warrant Units or Common Units into which such Deemed Warrant Units have been exercised in an amount equal to the product of (x) the number of such Common Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any remaining balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any Deemed Warrant Units. Following any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained Deemed Warrant Units, if any, will have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee’s Capital Account established with respect to the transferred Deemed Warrant Units or Common Units granted on exercise of the Deemed Warrant Units will have a balance equal to the amount allocated under clause (A) hereinabove.

(d)                                  (i)  Consistent with Treasury Regulation Sections 1.704-1(b)(2)(iv)(f) and 1.704-1(b)(2)(iv)(h)(2), on an issuance of additional Partnership Interests for cash or Contributed Property, the issuance of a Noncompensatory Option, the issuance of Partnership Interests as consideration for the provision of services, the conversion of a Class A Preferred Unit in accordance with Section 5.12(b) , the conversion of a Class B Preferred Unit in accordance with Section 5.13(e)  or the conversion of a Class C Preferred Unit in accordance with Section 5.14(e) , the Capital Accounts of all Partners and the Carrying Value of each Partnership property immediately prior to such issuance (or, in the case of a Conversion Date, immediately after such Conversion Date) shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property for an amount equal to its fair market value immediately prior to such issuance; provided, however , that in the event of the issuance of a Partnership Interest pursuant to the exercise of a Noncompensatory Option where the right to share in Partnership capital represented by such Partnership Interest differs from the consideration paid to acquire and exercise such option, the Carrying Value of each Partnership property immediately after the issuance of such Partnership Interest shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property and the Capital Accounts of the Partners shall be adjusted in a manner consistent with Treasury Regulation Section 1.704-1(b)(2)(iv)(s); provided, further , that in the event of an issuance of Partnership Interests for a de minimis amount of cash or Contributed Property, in the event of an issuance of a Noncompensatory Option to acquire a de minimis Partnership Interest, or in the event of an issuance of a de minimis amount of Partnership

52

Interests as consideration for the provision of services, the General Partner may determine that such adjustments are unnecessary for the proper administration of the Partnership. Any such Unrealized Gain or Unrealized Loss (or items thereof) shall be allocated (A) if the operation of this sentence is triggered by the conversion of a Class A Preferred Unit, a Class B Preferred Unit or a Class C Preferred Unit, first among the Partners holding Common Units as may be necessary to cause the Capital Account attributable to each Common Unit to be the same, and (B) any remaining Unrealized Gain or Unrealized Loss shall be allocated among the Partners pursuant to Section 6.1 in the same manner as any item of gain or loss actually recognized would have been allocated. If the Unrealized Gain or Unrealized Loss allocated as a result of the occurrence of a Conversion Date is not sufficient to cause the Capital Account attributable to each Common Unit to be the same, then Capital Account balances shall be reallocated between the Partners holding such Units so as to cause the Capital Account attributable to each Common Unit to be the same, in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3). In determining Unrealized Gain or Unrealized Loss in connection with the issuance of additional Partnership Interests or a Conversion Date, the aggregate cash amount and fair market value of all Partnership assets (including cash or cash equivalents) immediately prior to the issuance of additional Partnership Interests (or, in the case of an adjustment to the Carrying Value of Partnership property resulting from the exercise of a Noncompensatory Option (including conversion of a Class A Preferred Unit, Class B Preferred Unit or a Class C Preferred Unit) immediately after the issuance of the Partnership Interest acquired pursuant to the exercise of the Noncompensatory Option) shall be determined by the General Partner using such method of valuation as it may adopt in its sole discretion. For this purpose, the General Partner may determine that it is appropriate to first determine an aggregate value for the Partnership, based on the current trading price of the Common Units, the fair market value of all other Partnership Interests (on a fully converted basis) of all Partners at such time, and the amount of Partnership liabilities; and, if before the Conversion Date of any Class A Preferred Units, Class B Preferred Units or Class C Preferred Units or other Noncompensatory Options, may adjust the fair market value of all Partnership assets to reflect the difference, if any, between the fair market value of any Class A Preferred Units, Class B Preferred Units, Class C Preferred Units or other Noncompensatory Options for which the Conversion Date has not occurred and the aggregate Capital Accounts attributable to such Class A Preferred Units, Class B Preferred Units and Class C Preferred Units to the extent of any Unrealized Gain or Unrealized Loss that has not been reflected in the Partners’ Capital Accounts previously, consistent with the methodology of Treasury Regulation Section 1.704-1(b)(2)(iv)(h)(2). The General Partner shall allocate such aggregate value among the assets of the Partnership (in such manner as it determines) to arrive at a fair market value for individual properties.

(ii)                                   In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), immediately prior to any actual or deemed distribution to a Partner of any Partnership property (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the Capital Accounts of all Partners and the Carrying Value of all Partnership property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, and any such Unrealized Gain or Unrealized Loss shall be treated, for purposes of maintaining Capital Accounts, as if it had been recognized on an actual sale of each such property immediately prior to such distribution for an amount equal to its fair market value, and had been allocated among the Partners, at such time, pursuant to Section 6.1(c)  and

53

Section 6.1(d)  in the same manner as any item of gain or loss actually recognized following an event giving rise to the dissolution of the Partnership would have been allocated. In determining such Unrealized Gain or Unrealized Loss the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior to a distribution shall (A) in the case of an actual distribution that is not made pursuant to Section 12.4 or in the case of a deemed distribution, be determined in the same manner as that provided in Section 5.5(d)(i)  or (ii) in the case of a liquidating distribution pursuant to Section 12.4 , be determined by the Liquidator using such method of valuation as it may adopt.

Section 5.6                                    Issuances of Additional Partnership Interests .

(a)                                  Subject to the restrictions set forth in Section 5.12, Section 5.13 and Section 5.14, the Partnership may issue additional Partnership Interests and options, rights, warrants and appreciation rights relating to the Partnership Interests (including as described in Section 7.4(c)) for any Partnership purpose at any time and from time to time to such Persons for such consideration and on such terms and conditions as the General Partner shall determine, all without the approval of any Limited Partners.

(b)                                  Each additional Partnership Interest authorized to be issued by the Partnership pursuant to Section 5.6(a)  may be issued in one or more classes, or one or more series of any such classes, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of Partnership Interests), as shall be fixed by the General Partner, including (i) the right to share in Partnership profits and losses or items thereof; (ii) the right to share in Partnership distributions; (iii) the rights upon dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may or shall be required to redeem the Partnership Interest (including sinking fund provisions); (v) whether such Partnership Interest is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms and conditions upon which each Partnership Interest will be issued, evidenced by certificates and assigned or transferred; (vii) the method for determining the Percentage Interest as to such Partnership Interest; and (viii) the right, if any, of each such Partnership Interest to vote on Partnership matters, including matters relating to the relative rights, preferences and privileges of such Partnership Interest.

(c)                                   The General Partner shall take all actions that it determines to be necessary or appropriate in connection with (i) each issuance of Partnership Interests and options, rights, warrants and appreciation rights relating to Partnership Interests pursuant to this Section 5.6 , (ii) the conversion of the Combined Interest into Units pursuant to the terms of this Agreement, (iii) the issuance of Common Units pursuant to Section 5.11 , (iv) reflecting admission of such additional Limited Partners in the books and records of the Partnership as the Record Holder of such Limited Partner Interest and (v) all additional issuances of Partnership Interests. The General Partner shall determine the relative rights, powers and duties of the holders of the Units or other Partnership Interests being so issued. The General Partner shall do all things necessary to comply with the Delaware Act and is authorized and directed to do all things that it determines to be necessary or appropriate in connection with any future issuance of Partnership Interests or in connection with the conversion of the Combined Interest into Units pursuant to the terms of this Agreement, including compliance with any statute, rule, regulation or guideline of any

54

federal, state or other governmental agency or any National Securities Exchange on which the Units or other Partnership Interests are listed or admitted to trading.

(d)                                  No fractional Units shall be issued by the Partnership.

Section 5.7                                    Reserved .

Section 5.8                                    Limited Preemptive Right .  Except as provided in this Section 5.8 , in Section 5.2 , in Section 5.12 , in Section 5.13 , in Section 5.14 or as otherwise provided in a separate agreement by the Partnership, no Person shall have any preemptive, preferential or other similar right with respect to the issuance of any Partnership Interest, whether unissued or hereafter created. The General Partner shall have the right, which it may from time to time assign in whole or in part to any of its Affiliates or the beneficial owners thereof or any of their respective Affiliates, to purchase Partnership Interests from the Partnership whenever, and on the same terms that, the Partnership issues Partnership Interests to Persons other than the General Partner and its Affiliates or such beneficial owners or any of their respective Affiliates, to the extent necessary to maintain the Percentage Interests of the General Partner and its Affiliates and such beneficial owners or any of their respective Affiliates equal to that which existed immediately prior to the issuance of such Partnership Interests.

Section 5.9                                    Splits and Combinations .

(a)                                  Subject to Section 5.9(d), Section 6.6 and Section 6.9 (dealing with adjustments of distribution levels), the Partnership may make a Pro Rata distribution of Partnership Interests (other than Preferred Units) to all Record Holders or may effect a subdivision or combination of Partnership Interests so long as, after any such event, each Partner shall have the same Percentage Interest in the Partnership as before such event, and any amounts calculated on a per Unit basis or stated as a number of Units are proportionately adjusted retroactive to the beginning of the Partnership.

(b)                                  Whenever such a distribution, subdivision or combination of Partnership Interests is declared, the General Partner shall select a Record Date as of which the distribution, subdivision or combination shall be effective and shall send notice thereof at least 20 days prior to such Record Date to each Record Holder as of a date not less than 10 days prior to the date of such notice. The General Partner also may cause a firm of independent public accountants selected by it to calculate the number of Partnership Interests to be held by each Record Holder after giving effect to such distribution, subdivision or combination. The General Partner shall be entitled to rely on any certificate provided by such firm as conclusive evidence of the accuracy of such calculation.

(c)                                   Promptly following any such distribution, subdivision or combination, the Partnership may issue Certificates to the Record Holders of Partnership Interests as of the applicable Record Date representing the new number of Partnership Interests held by such Record Holders, or the General Partner may adopt such other procedures that it determines to be necessary or appropriate to reflect such changes. If any such combination results in a smaller total number of Partnership Interests Outstanding, the Partnership shall require, as a condition to

55

the delivery to a Record Holder of such new Certificate, the surrender of any Certificate held by such Record Holder immediately prior to such Record Date.

(d)                                  The Partnership shall not issue fractional Units upon any distribution, subdivision or combination of Units. If a distribution, subdivision or combination of Units would result in the issuance of fractional Units but for the provisions of Section 5.6(d)  and this Section 5.9(d) , each fractional Unit shall be rounded to the nearest whole Unit (and a 0.5 Unit shall be rounded to the next higher Unit).

Section 5.10                             Fully Paid and Non-Assessable Nature of Limited Partner Interests .  All Limited Partner Interests issued pursuant to, and in accordance with the requirements of, this Article V shall be fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Section 17-303, 17-607 or 17-804 of the Delaware Act.

Section 5.11                             Issuance of Common Units in Connection with Reset of Incentive Distribution Rights .

(a)                                  Subject to the provisions of this Section 5.11 , the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall have the right, at any time when the Partnership has made a distribution pursuant to Section 6.4(d)  for each of the four most recently completed Quarters and the amount of each such distribution did not exceed Adjusted Operating Surplus for such Quarter, to make an election (the “ IDR Reset Election ”) to cause the Minimum Quarterly Distribution and the Target Distributions to be reset in accordance with the provisions of Section 5.11(e)  and, in connection therewith, the holder or holders of the Incentive Distribution Rights will become entitled to receive their respective proportionate share of a number of Common Units (the “ IDR Reset Common Units ”) derived by dividing (i) the average amount of cash distributions made by the Partnership for the two full Quarters immediately preceding the giving of the Reset Notice (as defined in Section 5.11(b) ) in respect of the Incentive Distribution Rights by (ii) the average of the cash distributions made by the Partnership in respect of each Common Unit for the two full Quarters immediately preceding the giving of the Reset Notice (the “ Reset MQD ”) (the number of Common Units determined by such quotient is referred to herein as the “ Aggregate Quantity of IDR Reset Common Units ”).  The Percentage Interest of the General Partner after the issuance of the Aggregate Quantity of IDR Reset Common Units shall equal the Percentage Interest of the General Partner prior to the issuance of the Aggregate Quantity of IDR Reset Common Units and the General Partner shall not be obligated to make any additional Capital Contribution to the Partnership in order to maintain its Percentage Interest in connection therewith. The making of the IDR Reset Election in the manner specified in Section 5.11(b)  shall cause the Minimum Quarterly Distribution and the Target Distributions to be reset in accordance with the provisions of Section 5.11(e)  and, in connection therewith, the holder or holders of the Incentive Distribution Rights will become entitled to receive Common Units on the basis specified above, without any further approval required by the General Partner or the Unitholders, at the time specified in Section 5.11(c)  unless the IDR Reset Election is rescinded pursuant to Section 5.11(d) .

56

(b)                                  To exercise the right specified in Section 5.11(a) , the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall deliver a written notice (the “ Reset Notice ”) to the Partnership. Within 10 Business Days after the receipt by the Partnership of such Reset Notice, as the case may be, the Partnership shall deliver a written notice to the holder or holders of the Incentive Distribution Rights of the Partnership’s determination of the aggregate number of Common Units which each holder of Incentive Distribution Rights will be entitled to receive.

(c)                                   The holder or holders of the Incentive Distribution Rights will be entitled to receive the Aggregate Quantity of IDR Reset Common Units on the fifteenth Business Day after receipt by the Partnership of the Reset Notice; provided , however , that the issuance of Common Units to the holder or holders of the Incentive Distribution Rights shall not occur prior to the approval of the listing or admission for trading of such Common Units by the principal National Securities Exchange upon which the Common Units are then listed or admitted for trading if any such approval is required pursuant to the rules and regulations of such National Securities Exchange.

(d)                                  If the principal National Securities Exchange upon which the Common Units are then traded has not approved the listing or admission for trading of the Common Units to be issued pursuant to this Section 5.11 on or before the 30th calendar day following the Partnership’s receipt of the Reset Notice and such approval is required by the rules and regulations of such National Securities Exchange, then the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall have the right to either rescind the IDR Reset Election or elect to receive other Partnership Interests having such terms as the General Partner may approve, with the approval of the Conflicts Committee, that will provide (i) the same economic value, in the aggregate, as the Aggregate Quantity of IDR Reset Common Units would have had at the time of the Partnership’s receipt of the Reset Notice, as determined by the General Partner, and (ii) for the subsequent conversion of such Partnership Interests into Common Units within not more than 12 months following the Partnership’s receipt of the Reset Notice upon the satisfaction of one or more conditions that are reasonably acceptable to the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights).

(e)                                   The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution shall be adjusted at the time of the issuance of Common Units or other Partnership Interests pursuant to this Section 5.11 such that (i) the Minimum Quarterly Distribution shall be reset to equal the Reset MQD, (ii) the First Target Distribution shall be reset to equal 115% of the Reset MQD, (iii) the Second Target Distribution shall be reset to equal to 125% of the Reset MQD and (iv) the Third Target Distribution shall be reset to equal 150% of the Reset MQD.

(f)                                    Upon the issuance of IDR Reset Common Units pursuant to Section 5.11(a) , the Capital Account maintained with respect to the Incentive Distribution Rights shall (A) first, be allocated to IDR Reset Common Units in an amount equal to the product of (x) the Aggregate Quantity of IDR Reset Common Units and (y) the Per Unit Capital Amount for an Initial

57

Common Unit, and (B) second, any remaining balance in such Capital Account will be retained by the holder of the Incentive Distribution Rights. In the event that there is not a sufficient Capital Account associated with the Incentive Distribution Rights to allocate the full Per Unit Capital Amount for an Initial Common Unit to the IDR Reset Common Units in accordance with clause (A) of this Section 5.11(f) , the IDR Reset Common Units shall be subject to Section 6.1(d)(x)(B)  and Section 6.1(d)(x)(C) .

Section 5.12                             Establishment of Class A Preferred Units .

58

other than the Class A Preferred Unit Distribution, unless and until all accrued and unpaid Class A Preferred Unit Distributions have been paid in full in cash; provided , however , that distributions may be declared and paid in respect of the Class A Preferred Units and any Class A Parity Securities, as long as such distributions are declared and paid pro rata such that the amounts of distributions declared per Class A Preferred Unit and per unit of such Parity Security shall in all cases bear to each other the same ratio that accrued but unpaid and accumulated distributions per Class A Preferred Unit and per unit of such Parity Security bear to each other. Notwithstanding anything in this Section 5.12(b)  to the contrary, at no time shall the Deficiency Rate exceed $0.3385.

(ii)                                   If a Payment Default has occurred, then the amount of any accrued but unpaid Class A Preferred Unit Distributions for which the Class A Distribution Payment Date has passed but for which no payment has been made shall be increased at an annual rate of 10.75%, compounded Quarterly, until all accrued and unpaid Class A Preferred Unit Distributions have been paid in full in cash.

(iii)                                Subject to and without limiting the other provisions of this Section 5.12(b) , each Class A Preferred Unit shall have the right to share in any special distributions by the Partnership of cash, securities or other property and in the form of such cash, securities or other property Pro Rata with the Common Units, as if the Class A Preferred Units had converted into Common Units at the Class A Conversion Rate then in effect, provided that special distributions shall not include regular Quarterly distributions paid in the normal course pursuant to Section 6.3(a) .

(iv)                               Class A Preferred Unit Distributions shall accrue on a daily basis; provided , however , that, with respect to any Class A Preferred Unit that is converted into Common Units in accordance with Section 5.12(d)(iii) , the holder thereof shall not be entitled to both a Class A Preferred Unit Distribution and a Common Unit distribution in respect of (A) the most recently completed Quarter or (B) the Quarter in which the conversion is consummated, but shall be entitled only to the distribution to be paid based upon the class of Units held as of the close of business on the Record Date in respect of each such Quarter.

(v)                                  All Class A Preferred Unit Distributions shall be paid Quarterly, in arrears, on the earlier of: (A) the date that distributions are made on the Common Units for such Quarter pursuant to Section 6.3(a)  or such earlier date after the end of such Quarter as the General Partner may determine, and (B) the date that is forty-five (45) days after the end of such Quarter (such date, the “ Class A Distribution Payment Date ”); provided , however , that if any Class A Distribution Payment Date would otherwise occur on a day that is not a Business Day, then such Class A Distribution Payment Date shall instead be the immediately succeeding Business Day.

(vi)                               For the avoidance of doubt and notwithstanding anything in Section 6.4 or Section 6.5 to the contrary, any Available Cash that is to be distributed pursuant to Section 6.4 or Section 6.5 shall be distributed first in accordance with this Section 5.12(b); provided , however , that for purposes of this Section 5.12(b) , Available Cash

The Partnership shall give each Class A Preferred Holder at least thirty (30) days prior written notice of any voluntary liquidation or winding-up of the Partnership or any Class A Change of Control. Each Class A Preferred Unit converted into Common Units pursuant to this Section 5.12(d)(i)  shall be converted into a number of Common Units equal to the Class A Conversion Rate then in effect. In the case of any Certificate representing Class A Preferred Units which are converted in part only, upon such conversion the Transfer Agent shall authenticate and deliver to the Class A Preferred Holder thereof, at the expense of the Partnership, a new Certificate representing the number of Class A Preferred Units not so converted.

(ii)                                   At any time after the eighth anniversary of the Initial Class A Closing Date, if all of the Forced Conversion Conditions are satisfied as of the Class A Conversion Date (other than the Class A Conversion Notice Conditions, which need only to be satisfied as of the date of the Class A Conversion Notice), the General Partner, in its sole discretion, shall have the right (the “ Forced Conversion Right ”) to convert all, but not less than all, of the Outstanding Class A Preferred Units into Common Units. To exercise the Forced Conversion Right, the Partnership shall deliver to each Class A Preferred Holder a written notice (the “ Class A Conversion Notice ”) not more than five (5) and not less than three (3) Business Days prior to the expected Class A Conversion Date. Immediately as of the close of business on the date of conversion pursuant to this Section 5.12(d)(ii) , which date shall not be (A) prior to the third Business Day following the date of the Class A Conversion Notice and (B) with respect to any conversion of a Class A Preferred Unit that shall be settled in Common Units, prior the Record Date in respect of the most recently completed Quarter, each Outstanding Class A Preferred Unit shall automatically convert into a number of Common Units equal to the Class A Conversion Rate then in effect.

(iii)                                Except as set forth below, the conversion of a Class A Preferred Unit pursuant to this Section 5.12(d)  shall be settled, in the sole discretion of the General Partner, in cash or in Common Units, with settlements in cash being paid at the Cash Conversion Price; provided that in a conversion of multiple Class A Preferred Units, a portion of such Class A Preferred Units may, in the Company’s sole discretion, be settled

62

in cash with the remainder being settled in Common Units; provided , further , that the ratio of Class A Preferred Units being settled in cash to Class A Preferred Units being settled in Common Units shall be the same for all then-converting Class A Preferred Holders. The Partnership shall deliver written notice of the General Partner’s election as to method of settlement of a conversion of a Class A Preferred Unit to each then-converting Class A Preferred Holder at least three (3) Business Days prior to the expected Class A Conversion Date. Notwithstanding the foregoing, the Partnership shall make a cash payment with respect to each Class A Preferred Unit converted pursuant to this Section 5.12(d) , in an amount equal to all accrued but unpaid and accumulated distributions, including any distributions accrued and unpaid at the Deficiency Rate, on such Class A Preferred Unit to, but not including, the Class A Conversion Date; provided , however , that, with respect to any Class A Preferred Unit, the conversion of which shall be settled in Common Units, such accrued but unpaid and accumulated distributions shall not include any Class A Preferred Unit Distribution accrued in respect of (A) the most recently completed Quarter, if the Record Date in respect of such Quarter has not yet passed, or (B) the Quarter in which the conversion is consummated.

(iv)                               In lieu of issuing any fractional Common Unit upon the conversion of a Class A Preferred Unit pursuant to this Section 5.12(d) , the Partnership shall, in the sole discretion of the General Partner, round the number of Common Units issued upon conversion of each Class A Preferred Unit (A) up to the nearest whole Common Unit or (B) down to the nearest whole Common Unit and pay cash in lieu of any such fractional Common Unit.

(v)                                  Upon conversion, the rights of a holder of converted Class A Preferred Units as a Class A Preferred Holder shall cease with respect to such converted Class A Preferred Units, including any rights under this Agreement with respect to Class A Preferred Holders, and such Person shall continue to be a Limited Partner and have the rights of a holder of Common Units under this Agreement and the rights of a Class A Preferred Holder in respect of any Class A Preferred Units not converted. Each Class A Preferred Unit shall, upon its Class A Conversion Date, be deemed to be transferred to, and cancelled by, the Partnership in exchange for the issuance of the Common Unit(s) into which such Class A Preferred Unit converted. Notwithstanding the foregoing, as the result of a conversion, a holder shall not lose or relinquish any claims or rights of action such holder may then or thereafter have as a result of such holder’s ownership of the converted Class A Preferred Units.

(vi)                               The Partnership shall pay any documentary, stamp or similar issue or transfer taxes or duties relating to the issuance or delivery of Common Units upon conversion of the Class A Preferred Units. However, the Class A Preferred Holder whose Class A Preferred Units are converted shall pay any tax or duty which may be payable relating to any transfer involving the issuance or delivery of Common Units in a name other than the holder’s name. The Transfer Agent may refuse to deliver the Certificate representing Common Units (or notation of book entry) being issued in a name other than the holder’s name until the Transfer Agent receives a sum sufficient to pay any tax or duties due because the Units are to be issued in a name other than the holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation.

63

(vii)                            The Partnership shall keep free from preemptive rights a sufficient number of Common Units to permit the conversion of all outstanding Class A Preferred Units into Common Units to the extent provided in, and in accordance with, this Section 5.12(d) .

(viii)                         All Common Units delivered upon conversion of the Class A Preferred Units in accordance with this Section 5.12(d)  shall be (1) newly issued and (2) duly authorized, validly issued, fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Section 17-303, 17-607 or 17-804 of the Delaware Act, and shall be free from preemptive rights and free of any lien, claim, rights or encumbrances, other than those arising under the Delaware Act or this Agreement and other than restrictions on transfer under applicable securities laws.

(ix)                               The Partnership shall comply with all applicable securities laws pertaining to the issuance of any Common Units upon conversion of Class A Preferred Units and, if the Common Units are then listed, quoted or admitted to trading on the New York Stock Exchange or any other National Securities Exchange or other market, shall list or cause to have quoted or admitted to trading and keep listed, quoted or admitted to trading the Common Units issuable upon conversion of the Class A Preferred Units to the extent permitted or required by the rules of such exchange or market.

(x)                                  If, after the Initial Class A Closing Date, the Partnership (A) makes a distribution on its Common Units in Common Units, (B) subdivides or splits its outstanding Common Units into a greater number of Common Units, (C) combines or reclassifies its Common Units into a smaller number of Common Units or (D) issues by reclassification of its Common Units any Partnership Interests (including any reclassification in connection with a merger, consolidation or business combination in which the Partnership is the surviving Person), then the Class A Conversion Price in effect at the time of the Record Date for such distribution or of the effective date of such subdivision, split, combination, or reclassification shall be proportionately adjusted so that the conversion of the Class A Preferred Units after such time shall entitle the holder to receive the aggregate number of Common Units (or shares of any Partnership Interests into which such shares of Common Units would have been combined, consolidated, merged or reclassified pursuant to clauses (C) and (D) above) that such holder would have been entitled to receive if the Class A Preferred Units had been converted into Common Units immediately prior to such Record Date or effective date, as the case may be, and in the case of a merger, consolidation or business combination in which the Partnership is the surviving Person, the Partnership shall provide effective provisions to ensure that the provisions of this Section 5.12 relating to the Class A Preferred Units shall not be abridged or amended and that the Class A Preferred Units shall thereafter retain the same powers, preferences and relative participating, optional and other special rights, and the qualifications, limitations and restrictions thereon, that the Class A Preferred Units had immediately prior to such transaction or event. An adjustment made pursuant to this Section 5.12(d)(x)  shall become effective immediately after the Record Date in the case of a distribution and shall become effective immediately after the effective date in the case of a subdivision, combination, reclassification (including any reclassification in connection with a merger, consolidation or business combination in which the

64

Partnership is the surviving Person) or split. Such adjustment shall be made successively whenever any event described above shall occur.

(e)                                   Change of Control.   In the event of a Class A Change of Control, each Class A Preferred Holder shall have the option, at its sole election, to:

(i)                                      require the Partnership to redeem in cash the Class A Preferred Units held by such Class A Preferred Holder at a price per Class A Preferred Unit equal to the Class A Change of Control Redemption Premium, plus any accrued but unpaid and accumulated distributions, including any distributions accrued and unpaid at the Deficiency Rate, on such Class A Preferred Units to, but not including, the Class A Redemption Date;

(ii)                                   if the Partnership is the surviving entity following such Class A Change of Control, continue to hold Class A Preferred Units; or

(iii)                                convert all, but not less than all, of the Class A Preferred Units held by such Class A Preferred Holder into Common Units, at the Class A Conversion Rate then in effect, in accordance with applicable provisions of Section 5.12(d) .

(f)                                    Redemption .

(i)                                      At any time after the first anniversary of the Initial Class A Closing Date, and subject to the right of a Class A Preferred Holder to elect conversion after the Initial Conversion Date pursuant to Section 5.12(d)(i) (B)(1), the Partnership may redeem in cash all or a portion of the Outstanding Class A Preferred Units at a price per Class A Preferred Unit equal to the then applicable Class A Redemption Premium, plus any accrued but unpaid and accumulated distributions, including any distributions accrued and unpaid at the Deficiency Rate, on such Class A Preferred Units to, but not including, the Class A Redemption Date (the “ Voluntary Redemption Right ”), by providing written notice (the “ Voluntary Redemption Notice ”) to the Class A Preferred Holders not more than 45 and not less than 10 days (if the expected Class A Redemption Date is on or prior to the Initial Conversion Date) or 20 days (if the expected Class A Redemption Date is after the Initial Conversion Date) in advance of the expected Class A Redemption Date set forth therein. Upon delivery of a Voluntary Redemption Notice, the Partnership shall be irrevocably obligated to redeem the Class A Preferred Units on the expected Class A Redemption Date set forth in such notice. If the Partnership elects to redeem less than all of the Outstanding Class A Preferred Units pursuant to this Section 5.12(f)(i) , then such redemption will be paid on a pro rata basis based on the number of Class A Preferred Units held by each Class A Preferred Holder prior to such redemption.

(ii)                                   Prior to the redemption or repurchase of one or more classes of Class A Parity Securities (collectively, the “ Parity Redemption Securities ”), the Partnership shall, by written notice to the Class A Preferred Holders (the “ Notice of Parity Redemption ”), offer to redeem the Outstanding Class A Preferred Units in cash on a pro rata basis with such Parity Redemption Securities, at a price per Class A Preferred Unit equal to the applicable Class A Redemption Premium, plus any accrued but unpaid and accumulated

65

distributions, including any distributions accrued and unpaid at the Deficiency Rate, on such Class A Preferred Units to, but not including, the Class A Redemption Date; provided , however , that if any Class A Preferred Holder fails to provide written notice of its intent to exercise its right to request redemption of its Class A Preferred Units within fifteen (15) Business Days of the Notice of Parity Redemption, such Class A Preferred Holder shall be deemed to have waived any and all rights to redemption pursuant to this Section 5.12(f)(ii)  in such transaction. For purposes of this Section 5.12(f)(ii) , the pro rata allocation between the Class A Preferred Holders that elect to exercise their right to redemption pursuant to this Section 5.12(f)(ii)  and the holders of such Parity Redemption Securities shall be based on the relative liquidation preferences of the securities held by the respective holders.

The Partnership shall not have right to cause the redemption of Class A Preferred Units except as set forth in Section 5.12(f)(i) .

(g)                                   Preemptive Rights .  Prior to the issuance of any Class A Parity Securities or Class A Senior Securities, the Partnership shall, by written notice to the Class A Preemptive Rights Holders (the “ Notice of Issuance ”), offer to sell such Class A Parity Securities or Class A Senior Securities to the Class A Preemptive Rights Holders on terms and subject to conditions determined by the General Partner to be reasonable, which offer shall be made on a pro rata basis such that each Class A Preemptive Rights Holder shall be entitled to purchase a portion of such Class A Parity Securities or Class A Senior Securities equal to the quotient of (i) the number of Class A Preferred Units held by such Class A Preemptive Rights Holder on the date of the Notice of Issuance divided by (ii) the aggregate number of Class A Preferred Units held by all Class A Preemptive Rights Holders on the date of the Notice of Issuance (or as the Class A Preemptive Rights Holders may at such time otherwise agree among themselves); provided , that the offer of such Class A Parity Securities or Class A Senior Securities shall not be on a basis less favorable to the Class A Preemptive Rights Holders than is contemplated with respect to any purchaser thereof who is not a Class A Preemptive Rights Holder; provided , further , that (A) if any Class A Preemptive Rights Holder fails to provide written notice of its intent to exercise its right to purchase such Class A Parity Securities or Class A Senior Securities within fifteen (15) Business Days of the Notice of Issuance, such Class A Preemptive Rights Holder shall be deemed to have waived any and all rights to purchase such securities in such transaction and (B) if any Class A Preemptive Rights Holder waives or is deemed to have waived its right to purchase such Class A Parity Securities or Class A Senior Securities, the other Class A Preemptive Rights Holders shall be entitled to exercise such right as if such right was initially granted to such Class A Preemptive Rights Holders. Notwithstanding the foregoing, in no event shall the Partnership be obligated to offer to sell Class A Parity Securities or Class A Senior Securities to the Class A Preferred Holders pursuant to this Section 5.12(g)  in connection with any (1) securities issued to the owners of another entity in connection with the acquisition of such entity by the Partnership by merger, consolidation, sale or exchange of securities, purchase of substantially all of the assets, or other reorganization whereby the Partnership acquires more than 50% of the voting power or assets of such entity; (2) Common Units or other Class A Junior Securities (including options to purchase Common Units or other Class A Junior Securities and Common Units or other Class A Junior Securities issued upon exercise of such options) issued to

(iii)                                In connection with a sale of Class A Preferred Units pursuant to an effective registration statement or in reliance on Rule 144 of the rules and regulations promulgated under the Securities Act, upon receipt by the Partnership of such information as the Partnership reasonably deems necessary to determine that the sale of the Class A Preferred Units is made in compliance with Rule 144, the Partnership shall remove or cause to be removed the restrictive legend from the certificate(s) representing such Class A Preferred Units (or the book-entry account maintained by the Transfer Agent), and the Partnership shall bear all costs associated therewith.

Section 5.13                             Establishment of Class B Preferred Units .

(a)                                  General .  The General Partner hereby designates and creates a series of Units to be designated as “9.00% Class B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units,” having the terms and conditions set forth herein.

(i)                                      Each Class B Preferred Unit shall be identical in all respects to every other Class B Preferred Unit, except as to the respective dates from which Class B Preferred Unit Distributions may begin accumulating, to the extent such dates may differ. The Class B Preferred Units represent perpetual equity interests in the Partnership and, except as set forth in Section 5.13(d)  and Section 5.13(e) , shall not give rise to a claim by the Partnership or a Class B Preferred Holder for redemption or the conversion thereof, as applicable, at a particular date.

(ii)                                   The authorized number of Class B Preferred Units shall be unlimited. Class B Preferred Units that are purchased or otherwise acquired by the Partnership shall be cancelled.

(iii)                                The Class B Preferred Units shall be represented by one or more global Certificates registered in the name of the Class B Securities Depositary or its nominee, and no Class B Preferred Holder shall be entitled to receive a definitive Certificate evidencing its Class B Preferred Units, unless otherwise required by law or the Class B Securities Depositary gives notice of its intention to resign or is no longer eligible to act as such with respect to the Class B Preferred Units and the Partnership shall have not selected a substitute Class B Securities Depositary within 60 calendar days thereafter. So long as the Class B Securities Depositary shall have been appointed and is serving with respect to the Class B Preferred Units, payments and communications made by the Partnership to Class B Preferred Holders shall be made by making payments to, and communicating with, the Class B Securities Depositary.

(b)                                  Distributions .

(i)                                      Distributions on each Outstanding Class B Preferred Unit (“ Class B Preferred Unit Distributions ”) shall be cumulative and shall accumulate at the applicable Class B Distribution Rate from and including the Class B Original Issue Date (or, for any subsequently issued and newly Outstanding Class B Preferred Units, from and including the Class B Distribution Payment Date immediately preceding the issue date of such Class B Preferred Units) until such time as the Partnership pays the applicable Class B

68

Preferred Unit Distribution or redeems such Class B Preferred Unit in accordance with Section 5.13(d)  or such Class B Preferred Unit is converted in accordance with Section 5.13(e) , regardless of whether such Class B Preferred Unit Distributions shall have been declared.

(ii)                                   Unless otherwise determined by the General Partner, Class B Preferred Unit Distributions shall be deemed to have been paid out of Available Cash with respect to the Quarter ended immediately preceding the Quarter in which the Class B Preferred Unit Distribution is made; provided , however , that for purposes of this Section 5.13(b) , Available Cash shall not include any deduction to provide funds for distributions under Section 6.4 or Section 6.5 in respect of any one or more of the next four Quarters. Class B Preferred Unit Distributions will be paid on an equal priority basis with distributions on any Outstanding Class B Parity Securities, including the Class A Preferred Units and the Class C Preferred Units.

(iii)                                Class B Preferred Unit Distributions, to the extent declared by the General Partner to be paid by the Partnership in accordance with this Section 5.13(b) , shall be paid quarterly, in arrears, on each Class B Distribution Payment Date. Class B Preferred Unit Distributions shall accumulate in each Class B Distribution Period from and including the first day of such Class B Distribution Period, to and including the last day of such Class B Distribution Period (other than the initial Class B Preferred Unit Distribution, which shall accumulate from and including the Class B Original Issue Date, to and including September 30, 2017); provided , however , that if the Partnership fails to pay in full in cash any Class B Preferred Unit Distribution on a Class B Distribution Payment Date, then the amount of such accumulated but unpaid Class B Preferred Unit Distribution shall increase at the then-applicable Class B Distribution Rate, until all accumulated and unpaid distributions on the Class B Preferred Units have been paid in full in cash.

(iv)                               Class B Preferred Unit Distributions shall be payable based on a 360-day year consisting of four 90-day periods. All Class B Preferred Unit Distributions payable by the Partnership pursuant to this Section 5.13(b)  shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code.  The guaranteed payment with respect to any Class B Distribution Period shall be for the account of the holders of Class B Preferred Units as of the applicable Class B Distribution Record Date.

(v)                                  Not later than 5:00 p.m. (New York City time) on each Class B Distribution Payment Date, the Partnership shall pay those Class B Preferred Unit Distributions, if any, that shall have been declared by the General Partner to Class B Preferred Holders as such holders’ names appear on the Partnership’s unit transfer books maintained by the registrar and Transfer Agent for the Class B Preferred Units on the Class B Distribution Record Date for the applicable Class B Preferred Unit Distribution.

(vi)                               So long as any Class B Preferred Units are Outstanding, no distribution shall be declared or paid or set aside for payment on any Class B Junior Securities (other

69

than a distribution payable solely in Class B Junior Securities) unless full cumulative Class B Preferred Unit Distributions and full cumulative distributions on any Class B Parity Securities have been or contemporaneously are being paid or set aside for payment on all Outstanding Class B Preferred Units and any such Class B Parity Securities, respectively, through the most recent Class B Distribution Payment Date, with respect to Outstanding Class B Preferred Units, and the most recent distribution payment date, with respect to any such Class B Parity Securities. Accumulated Class B Preferred Unit Distributions in arrears for any past Class B Distribution Period may be declared by the General Partner and paid on any date fixed by the General Partner, regardless of whether a Class B Distribution Payment Date, to Class B Preferred Holders on the Record Date for such payment, which may not be less than 10 days before such payment date. Subject to the next succeeding sentence, if all accumulated Class B Preferred Unit Distributions in arrears on all Outstanding Class B Preferred Units and all accumulated distributions in arrears on any Class B Parity Securities shall not have been declared and paid, or if sufficient funds for the payment thereof shall not have been set aside, payment of accumulated Class B Preferred Unit Distributions in arrears on the Class B Preferred Units and accumulated distributions in arrears on any such Class B Parity Securities shall be made in order of their respective distribution payment dates, commencing with the earliest distribution payment date. If less than all Class B Preferred Unit Distributions payable with respect to all Outstanding Class B Preferred Units and all distributions payable with respect to any Class B Parity Securities are paid, then such partial payment shall be declared and paid pro rata such that the amounts of Class B Preferred Unit Distributions declared and paid per Class B Preferred Unit and the amounts of distributions declared and paid per unit of such Class B Parity Securities shall in all cases bear to each other the same ratio that unpaid and accumulated Class B Preferred Unit Distributions per Class B Preferred Unit and unpaid and accumulated distributions per unit of such Class B Parity Securities bear to one another.

(vii)                            Subject to Section 12.4 and Section 5.13(d) , Class B Preferred Holders shall not be entitled to any distribution, whether payable in cash, property or Partnership Securities, in excess of full cumulative Class B Preferred Unit Distributions. Except insofar as distributions accumulate on the amount of any accumulated and unpaid Class B Preferred Unit Distributions as described in Section 5.13(b)(iii) , no interest or sum of money in lieu of interest shall be payable in respect of any distribution payment that may be in arrears on the Class B Preferred Units.

(viii)                         So long as the Class B Preferred Units are held of record by the Class B Securities Depositary or its nominee, declared Class B Preferred Unit Distributions shall be paid to the Class B Securities Depositary in same-day funds on each Class B Distribution Payment Date or other distribution payment date in the case of payments for Class B Preferred Unit Distributions in arrears.

(c)                                   Voting Rights .

(i)                                      Notwithstanding anything to the contrary in this Agreement, the Class B Preferred Units shall have no voting rights and no rights to consent or approve any action

70

or matter, except as set forth in this Section 5.13(c) , Section 13.3 , or as otherwise required by Delaware law.

(ii)                                   Without the affirmative vote or consent of the holders of at least two-thirds of the Outstanding Class B Preferred Units, voting as a separate class, the General Partner shall not adopt any amendment to this Agreement that would have a material adverse effect on the terms of the Class B Preferred Units; provided , however , that (x) subject to Section 5.13(c)(iii) , the issuance of additional Partnership Interests shall not be deemed to constitute such a material adverse effect for purposes of this Section 5.13(c)(ii)  and (y) for purposes of this Section 5.13(c)(ii) , no amendment of this Agreement in connection with a merger or other transaction in which the Partnership is the surviving entity and the Class B Preferred Units remain Outstanding with the terms thereof materially unchanged in any respect adverse to the Class B Preferred Holders shall be deemed to materially and adversely affect the powers, preferences, duties or special rights of the Class B Preferred Units.

(iii)                                Without the affirmative vote or consent of the holders of at least two-thirds of the Outstanding Class B Preferred Units, voting as a single class with holders of any Class B Parity Securities created after the Class B Original Issue Date and upon which like voting rights have been conferred and are exercisable, the Partnership shall not (x) create or issue any additional Class B Parity Securities (including any additional Class A Preferred Units) if the cumulative distributions payable on the then-Outstanding Class B Preferred Units or Class B Parity Securities are in arrears or (y) create or issue any Class B Senior Securities.

(iv)                               For any matter described in this Section 5.13(c)  in which the Class B Preferred Holders are entitled to vote as a class (whether separately or together with the holders of any Class B Parity Securities), such Class B Preferred Holders shall be entitled to one vote per Class B Preferred Unit. Any Class B Preferred Units held by the Partnership or any of its Subsidiaries or their controlled Affiliates shall not be entitled to vote.

(d)                                  Optional Redemption .

(i)                                      The Partnership shall have the right (A) at any time, and from time to time, on or after July 1, 2022, or (B) at any time within 120 days after the first date on which a Class B Change of Control occurs (the “ Class B Change of Control Redemption Period ”), in each case, to redeem the Class B Preferred Units, which redemption may be in whole or in part, using any source of funds legally available for such purpose. Any such redemption shall occur on a date set by the General Partner (the “ Class B Redemption Date ”). The Partnership shall effect any such redemption by paying cash for each Class B Preferred Unit to be redeemed equal to the Class B Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class B Redemption Date. So long as the Class B Preferred Units to be redeemed are held of record by the nominee of the Class B Securities Depositary, the Class B Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class B Redemption Date shall

71

be paid by the Paying Agent to the Class B Securities Depositary on the Class B Redemption Date.

(ii)                                   The Partnership shall give written notice of any redemption by mail, postage prepaid, not less than 30 days and not more than 60 days before the scheduled Class B Redemption Date, to the Class B Preferred Holders (as of 5:00 p.m. (New York City time) on the Business Day next preceding the day on which notice is given) of any Class B Preferred Units to be redeemed as such Class B Preferred Holders’ names appear on the Partnership’s unit transfer books maintained by the registrar and Transfer Agent and at the address of such Class B Preferred Holders shown therein. Such notice (the “ Class B Redemption Notice ”) shall state, as applicable:  (A) the Class B Redemption Date, (B) the number of Class B Preferred Units to be redeemed and, if less than all Outstanding Class B Preferred Units are to be redeemed, the number (and, in the case of Class B Preferred Units in certificated form, the identification) of Class B Preferred Units to be redeemed from such Class B Preferred Holder, (C) the Class B Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class B Redemption Date, (D) the place where any Class B Preferred Units in certificated form are to be redeemed and shall be presented and surrendered for payment of the Class B Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class B Redemption Date, therefor and (E) that Class B Preferred Unit Distributions on the Class B Preferred Units to be redeemed shall cease to accumulate from and after such Class B Redemption Date.

(iii)                                If the Partnership elects to redeem fewer than all of the Outstanding Class B Preferred Units, the number of Class B Preferred Units to be redeemed shall be determined by the General Partner, and such Class B Preferred Units shall be redeemed by such method of selection as the Class B Securities Depositary shall determine, either Pro Rata or by lot, with adjustments to avoid redemption of fractional Class B Preferred Units. The aggregate Class B Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class B Redemption Date for any such partial redemption of the Outstanding Class B Preferred Units shall be allocated correspondingly among the redeemed Class B Preferred Units. The Class B Preferred Units not redeemed shall remain Outstanding and entitled to all the rights and preferences provided in this Section 5.13 .

(iv)                               If the Partnership gives or causes to be given a Class B Redemption Notice, then the Partnership shall deposit with the Paying Agent funds sufficient to redeem the Class B Preferred Units as to which such Class B Redemption Notice shall have been given by no later than 10:00 a.m. (New York City time) on the Class B Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Class B Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class B Redemption Date, to the Class B Preferred Holders whose Class B Preferred Units are to be redeemed upon surrender or deemed surrender (which shall occur automatically if the Certificate representing such Class B Preferred Units is issued in the name of the Class B Securities Depositary or its nominee) of the Certificates therefor as set forth in the Class B

72

Redemption Notice. If the Class B Redemption Notice shall have been given, then from and after the Class B Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Class B Redemption Notice, all Class B Preferred Unit Distributions on such Class B Preferred Units to be redeemed shall cease to accumulate and all rights of Class B Preferred Holders of such Class B Preferred Units as Limited Partners with respect to such Class B Preferred Units shall cease, except the right to receive the Class B Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class B Redemption Date, regardless of whether declared, and such Class B Preferred Units shall not thereafter be transferred on the Partnership’s unit transfer books maintained by the registrar and Transfer Agent or be deemed to be Outstanding for any purpose whatsoever. The Class B Preferred Holders shall have no claim to the interest income, if any, earned on such funds deposited with the Paying Agent. Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including, but not limited to, redemption of Class B Preferred Units, that remain unclaimed or unpaid one year after the applicable Class B Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment, the Class B Preferred Holders entitled to such redemption or other payment shall have recourse only to the Partnership. Notwithstanding any Class B Redemption Notice, there shall be no redemption of any Class B Preferred Units called for redemption until funds sufficient to pay the full Class B Redemption Price of such Class B Preferred Units, plus all accumulated and unpaid Class B Preferred Unit Distributions to, but not including, the applicable Class B Redemption Date, regardless of whether declared, shall have been deposited by the Partnership with the Paying Agent.

(v)                                  Any Class B Preferred Units that are redeemed or otherwise acquired by the Partnership shall be cancelled. If only a portion of the Class B Preferred Units represented by a Certificate shall have been called for redemption, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Class B Preferred Units is registered in the name of the Class B Securities Depositary or its nominee), the Partnership shall issue and the Paying Agent shall deliver to such Class B Preferred Holder a new Certificate (or adjust the applicable book-entry account) representing the number of Class B Preferred Units represented by the surrendered Certificate that have not been called for redemption.

(vi)                               Notwithstanding anything to the contrary in this Section 5.13 , in the event that full cumulative distributions on the Class B Preferred Units and any Class B Parity Securities shall not have been paid or declared and set aside for payment, the Partnership shall not be permitted to repurchase, redeem or otherwise acquire, in whole or in part, any Class B Preferred Units or Class B Parity Securities except pursuant to a purchase or exchange offer made on the same relative terms to all Class B Preferred Holders and holders of any Class B Parity Securities. Subject to Section 4.10 , so long as any Class B Preferred Units are Outstanding, the Partnership shall not be permitted to redeem, repurchase or otherwise acquire any Common Units or any other Class B Junior Securities unless full cumulative distributions on the Class B Preferred Units and any Class B Parity Securities for all prior and the then-ending Class B Distribution Periods,

73

with respect to the Class B Preferred Units, and all prior and then-ending distribution periods, with respect to such Class B Parity Securities, shall have been paid or declared and set aside for payment.

(e)                                   Change of Control Conversion .

(i)                                      Upon the occurrence of a Class B Change of Control, each Class B Preferred Holder shall have the right (“ Class B Change of Control Conversion Right ”) to convert some or all of the Class B Preferred Units held by such Class B Preferred Holder on the Class B Change of Control Conversion Date into a number of Common Units per Class B Preferred Unit to be converted that is equal to the Class B Conversion Rate (such number of Common Units, the “ Class B Common Unit Conversion Consideration ”), unless the Partnership provides notice of its election to redeem Class B Preferred Units pursuant to Section 5.13(d)(i)(B)  prior to the expiration of the Class B Change of Control Redemption Period.

(ii)                                   Within five days following the expiration of the Class B Change of Control Redemption Period or, if earlier waived, the date of the Partnership’s waiver of its redemption right set forth in Section 5.13(d)(i)(B) , the Partnership will provide to the Class B Preferred Holders written notice (the “ Class B Conversion Notice ”) of the occurrence of the Class B Change of Control that describes the Class B Change of Control Conversion Right and states: (A) the events constituting the Class B Change of Control; (B) the date of the Class B Change of Control; (C) the date on which the Class B Change of Control Redemption Period expired or was waived; (D) the Class B Change of Control Conversion Date; (E) the last date on which the Class B Preferred Holders may exercise their Class B Change of Control Conversion Right; (F) the method and period for calculating the Common Unit Price with respect to the Class B Preferred Units; (G) if applicable, the type and amount of Class B Alternative Conversion Consideration entitled to be received per Class B Preferred Unit; (H) the name and address of the Paying Agent; and (I) the procedure that the Class B Preferred Holders must follow to exercise the Class B Change of Control Conversion Right.

(iii)                                In the case of a Class B Change of Control pursuant to which Common Units will be converted into cash, securities or other property or assets (including any combination thereof) (“ Class B Alternative Conversion Consideration ”), each Class B Preferred Holder electing to exercise its Class B Change of Control Conversion Right will receive upon conversion of the Class B Preferred Units elected by such Class B Preferred Holder the kind and amount of such Class B Alternative Conversion Consideration on a per Class B Preferred Unit basis that such Class B Preferred Holder would have owned or been entitled to receive upon the Class B Change of Control had such Class B Preferred Holder held a number of Common Units equal to the Class B Common Unit Conversion Consideration immediately prior to the effective time of the Class B Change of Control; provided , however, that, if the holders of Common Units have the opportunity to elect the form of consideration to be received in such Class B Change of Control, the consideration that the Class B Preferred Holders electing to exercise their Class B Change of Control Conversion Right will receive will be the form and proportion of the aggregate consideration elected by the holders of Common Units

74

who participate in the determination (based on the weighted average of elections) and will be subject to any limitations to which all holders of Common Units are subject, including, without limitation, pro rata reductions applicable to any portion of the consideration payable in the Class B Change of Control. The Partnership shall pay the cash value in lieu of issuing any fractional Common Units upon the conversion of the Class B Preferred Units.

(iv)                               Notwithstanding anything to the contrary in this Agreement, if prior to the expiration of the Class B Change of Control Redemption Period, the Partnership provides notice of its election to redeem Class B Preferred Units pursuant to Section 5.13(d)(i) , Class B Preferred Holders shall not have any right to convert (including pursuant to the Class B Change of Control Conversion Right) the Class B Preferred Units that the Partnership has elected to redeem, and any Class B Preferred Units subsequently selected for redemption that have been tendered for conversion pursuant to the Class B Change of Control Conversion Right shall be redeemed on the applicable Class B Redemption Date instead of converted on the Class B Change of Control Conversion Date.

(v)                                  Notwithstanding anything to the contrary in this Agreement, if prior to the Class B Change of Control Conversion Date, the Partnership provides notice of its election to redeem Class B Preferred Units pursuant to Section 5.13(d)(i) , Class B Preferred Holders of such Class B Preferred Units shall not have any right to convert (including pursuant to the Class B Change of Control Conversion Right) the Class B Preferred Units that the Partnership has elected to redeem, and any Class B Preferred Units subsequently selected for redemption that have been tendered for conversion pursuant to the Class B Change of Control Conversion Right shall be redeemed on the applicable Class B Redemption Date instead of converted on the Class B Change of Control Conversion Date.

(vi)                               The Partnership shall issue a press release for publication through a news or press organization as is reasonably expected to broadly disseminate the relevant information to the public, or post notice on the website of the Partnership, in any event prior to the opening of business on the first Business Day following any date on which the Partnership  provides the Class B Conversion Notice to the Class B Preferred Holders.

(vii)                            Each Class B Preferred Holder electing to exercise its Class B Change of Control Conversion Right will be required prior to the close of business on the third Business Day preceding the Class B Change of Control Conversion Date, to notify the Partnership of the number of Class B Preferred Units to be converted pursuant to the Class B Change of Control Conversion Right and otherwise to comply with any applicable procedures contained in the Class B Conversion Notice or otherwise required by the Class B Securities Depositary for effecting the conversion.

(viii)                         Upon conversion, the rights of each participating Class B Preferred Holder, as a holder of the Class B Preferred Units, shall cease with respect to such converted Class B Preferred Units, and each such Person shall continue to be a Partner and have the rights of a holder of Common Units under this Agreement in respect of the

75

Common Units constituting the Class B Conversion Common Units to be issued to such Person in respect of the converted Class B Preferred Units. Each Class B Preferred Unit shall, upon its Class B Change of Control Conversion Date, be deemed to be transferred to, and cancelled by, the Partnership in exchange for the issuance of the Class B Conversion Common Units.

(ix)                               The Partnership shall pay any documentary, stamp or similar issue or transfer taxes or duties relating to the issuance or delivery of Class B Conversion Common Units. However, the participating Class B Preferred Holder shall pay any tax or duty that may be payable relating to any transfer involving the issuance or delivery of Class B Conversion Common Units in a name other than such Class B Preferred Holder’s name. The Transfer Agent may refuse to reflect the notation of book entry (or the issuance of a Certificate) for Common Units being issued in a name other than the Class B Preferred Holder’s name until the Transfer Agent receives a sum sufficient to pay any tax or duties that will be due because the Common Units are to be issued in a name other than the Class B Preferred Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation.

(x)                                  The Partnership shall comply with all applicable securities laws regulating the offer and delivery of any Class B Conversion Common Units and, if the Common Units are then listed or quoted on a National Securities Exchange or other market, shall list or cause to have quoted and keep listed and quoted the Class B Conversion Common Units to the extent permitted or required by the rules of such exchange or market.

(xi)                               Notwithstanding anything herein to the contrary, nothing herein shall give to any Class B Preferred Holder any rights as a creditor in respect of its right to conversion of Class B Preferred Units.

(f)                                    Record Holders .  To the fullest extent permitted by applicable law, the General Partner, the Partnership, the Transfer Agent and the Paying Agent may deem and treat any Class B Preferred Holder as the true, lawful and absolute owner of the applicable Class B Preferred Units for all purposes, and neither the General Partner, the Partnership nor the Transfer Agent or the Paying Agent shall be affected by any notice to the contrary, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Class B Preferred Units are listed or admitted to trading.

(g)                                   Notices .  All notices or communications in respect of the Class B Preferred Units shall be sufficiently given if given in writing and delivered in person or by first class mail, postage prepaid, or if given in such other manner as may be permitted in this Section 5.13 , this Agreement or by applicable law.

(h)                                  Other Rights; Fiduciary Duties .  The Class B Preferred Units and the Class B Preferred Holders shall not have any designations, preferences, rights, powers or duties, other than as set forth in this Agreement or as provided by applicable law. Notwithstanding anything to the contrary in this Agreement or any duty existing at law, in equity or otherwise, to the fullest extent permitted by applicable law, neither the General Partner nor any other Indemnitee shall

76

owe any duties, including fiduciary duties, or have any liabilities to Class B Preferred Holders, other than the implied contractual covenant of good faith and fair dealing.

Section 5.14                             Establishment of Class C Preferred Units .

(a)                                  General .  The General Partner hereby designates and creates a series of Units to be designated as “9.625% Class C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units,” having the terms and conditions set forth herein.

(i)                                      Each Class C Preferred Unit shall be identical in all respects to every other Class C Preferred Unit, except as to the respective dates from which Class C Preferred Unit Distributions may begin accumulating, to the extent such dates may differ. The Class C Preferred Units represent perpetual equity interests in the Partnership and, except as set forth in Section 5.14(d)  and Section 5.14(e) , shall not give rise to a claim by the Partnership or a Class C Preferred Holder for redemption or the conversion thereof, as applicable, at a particular date.

(ii)                                   The authorized number of Class C Preferred Units shall be unlimited. Class C Preferred Units that are purchased or otherwise acquired by the Partnership shall be cancelled.

(iii)                                The Class C Preferred Units shall be represented by one or more global Certificates registered in the name of the Class C Securities Depositary or its nominee, and no Class C Preferred Holder shall be entitled to receive a definitive Certificate evidencing its Class C Preferred Units, unless otherwise required by law or the Class C Securities Depositary gives notice of its intention to resign or is no longer eligible to act as such with respect to the Class C Preferred Units and the Partnership shall have not selected a substitute Class C Securities Depositary within 60 calendar days thereafter. So long as the Class C Securities Depositary shall have been appointed and is serving with respect to the Class C Preferred Units, payments and communications made by the Partnership to Class C Preferred Holders shall be made by making payments to, and communicating with, the Class C Securities Depositary.

(b)                                  Distributions .

(i)                                      Distributions on each Outstanding Class C Preferred Unit (“ Class C Preferred Unit Distributions ”) shall be cumulative and shall accumulate at the applicable Class C Distribution Rate from and including the Class C Original Issue Date (or, for any subsequently issued and newly Outstanding Class C Preferred Units, from and including the Class C Distribution Payment Date immediately preceding the issue date of such Class C Preferred Units) until such time as the Partnership pays the applicable Class C Preferred Unit Distribution or redeems such Class C Preferred Unit in accordance with Section 5.14(d)  or such Class C Preferred Unit is converted in accordance with Section 5.14(e) , regardless of whether such Class C Preferred Unit Distributions shall have been declared.

(ii)                                   Unless otherwise determined by the General Partner, Class C Preferred Unit Distributions shall be deemed to have been paid out of Available Cash with respect

77

to the Quarter ended immediately preceding the Quarter in which the Class C Preferred Unit Distribution is made; provided , however , that for purposes of this Section 5.14(b) , Available Cash shall not include any deduction to provide funds for distributions under Section 6.4 or Section 6.5 in respect of any one or more of the next four Quarters. Class C Preferred Unit Distributions will be paid on an equal priority basis with distributions on any Outstanding Class C Parity Securities, including the Class A Preferred Units and the Class B Preferred Units.

(iii)                                Class C Preferred Unit Distributions, to the extent declared by the General Partner to be paid by the Partnership in accordance with this Section 5.14(b) , shall be paid quarterly, in arrears, on each Class C Distribution Payment Date. Class C Preferred Unit Distributions shall accumulate in each Class C Distribution Period from and including the first day of such Class C Distribution Period, to and including the last day of such Class C Distribution Period (other than the initial Class C Preferred Unit Distribution, which shall accumulate from and including the Class C Original Issue Date, to and including June 30, 2019); provided , however , that if the Partnership fails to pay in full in cash any Class C Preferred Unit Distribution on a Class C Distribution Payment Date, then the amount of such accumulated but unpaid Class C Preferred Unit Distribution shall increase at the then-applicable Class C Distribution Rate, until all accumulated and unpaid distributions on the Class C Preferred Units have been paid in full in cash.

(iv)                               Class C Preferred Unit Distributions shall be payable based on a 360-day year consisting of four 90-day periods. All Class C Preferred Unit Distributions payable by the Partnership pursuant to this Section 5.14(b)  shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code.  The guaranteed payment with respect to any Class C Distribution Period shall be for the account of the holders of Class C Preferred Units as of the applicable Class C Distribution Record Date.

(v)                                  Not later than 5:00 p.m. (New York City time) on each Class C Distribution Payment Date, the Partnership shall pay those Class C Preferred Unit Distributions, if any, that shall have been declared by the General Partner to Class C Preferred Holders as such holders’ names appear on the Partnership’s unit transfer books maintained by the registrar and Transfer Agent for the Class C Preferred Units on the Class C Distribution Record Date for the applicable Class C Preferred Unit Distribution.

(vi)                               So long as any Class C Preferred Units are Outstanding, no distribution shall be declared or paid or set aside for payment on any Class C Junior Securities (other than a distribution payable solely in Class C Junior Securities) unless full cumulative Class C Preferred Unit Distributions and full cumulative distributions on any Class C Parity Securities have been or contemporaneously are being paid or set aside for payment on all Outstanding Class C Preferred Units and any such Class C Parity Securities, respectively, through the most recent Class C Distribution Payment Date, with respect to Outstanding Class C Preferred Units, and the most recent distribution payment date, with respect to any such Class C Parity Securities. Accumulated Class C Preferred Unit

78

Distributions in arrears for any past Class C Distribution Period may be declared by the General Partner and paid on any date fixed by the General Partner, regardless of whether a Class C Distribution Payment Date, to Class C Preferred Holders on the Record Date for such payment, which may not be less than 10 days before such payment date. Subject to the next succeeding sentence, if all accumulated Class C Preferred Unit Distributions in arrears on all Outstanding Class C Preferred Units and all accumulated distributions in arrears on any Class C Parity Securities shall not have been declared and paid, or if sufficient funds for the payment thereof shall not have been set aside, payment of accumulated Class C Preferred Unit Distributions in arrears on the Class C Preferred Units and accumulated distributions in arrears on any such Class C Parity Securities shall be made in order of their respective distribution payment dates, commencing with the earliest distribution payment date. If less than all Class C Preferred Unit Distributions payable with respect to all Outstanding Class C Preferred Units and all distributions payable with respect to any Class C Parity Securities are paid, then such partial payment shall be declared and paid pro rata such that the amounts of Class C Preferred Unit Distributions declared and paid per Class C Preferred Unit and the amounts of distributions declared and paid per unit of such Class C Parity Securities shall in all cases bear to each other the same ratio that unpaid and accumulated Class C Preferred Unit Distributions per Class C Preferred Unit and unpaid and accumulated distributions per unit of such Class C Parity Securities bear to one another.

(vii)                            Subject to Section 12.4 and Section 5.14(d) , Class C Preferred Holders shall not be entitled to any distribution, whether payable in cash, property or Partnership Securities, in excess of full cumulative Class C Preferred Unit Distributions. Except insofar as distributions accumulate on the amount of any accumulated and unpaid Class C Preferred Unit Distributions as described in Section 5.14(b)(iii) , no interest or sum of money in lieu of interest shall be payable in respect of any distribution payment that may be in arrears on the Class C Preferred Units.

(viii)                         So long as the Class C Preferred Units are held of record by the Class C Securities Depositary or its nominee, declared Class C Preferred Unit Distributions shall be paid to the Class C Securities Depositary in same-day funds on each Class C Distribution Payment Date or other distribution payment date in the case of payments for Class C Preferred Unit Distributions in arrears.

(c)                                   Voting Rights .

(i)                                      Notwithstanding anything to the contrary in this Agreement, the Class C Preferred Units shall have no voting rights and no rights to consent or approve any action or matter, except as set forth in this Section 5.14(c) , Section 13.3 , or as otherwise required by Delaware law.

(ii)                                   Without the affirmative vote or consent of the holders of at least two-thirds of the Outstanding Class C Preferred Units, voting as a separate class, the General Partner shall not adopt any amendment to this Agreement that would have a material adverse effect on the terms of the Class C Preferred Units; provided , however , that (x) subject to Section 5.14(c)(iii) , the issuance of additional Partnership Interests shall not

79

be deemed to constitute such a material adverse effect for purposes of this Section 5.14(c)(ii)  and (y) for purposes of this Section 5.14(c)(ii) , no amendment of this Agreement in connection with a merger or other transaction in which the Partnership is the surviving entity and the Class C Preferred Units remain Outstanding with the terms thereof materially unchanged in any respect adverse to the Class C Preferred Holders shall be deemed to materially and adversely affect the powers, preferences, duties or special rights of the Class C Preferred Units.

(iii)                                Without the affirmative vote or consent of the holders of at least two-thirds of the Outstanding Class C Preferred Units, voting as a single class with holders of the Class B Preferred Units and any Class C Parity Securities created after the Class C Original Issue Date and upon which like voting rights have been conferred and are exercisable, the Partnership shall not (x) create or issue any additional Class C Parity Securities (including any additional Class A Preferred Units or Class B Preferred Units) if the cumulative distributions payable on the then-Outstanding Class C Preferred Units or Class C Parity Securities are in arrears or (y) create or issue any Class C Senior Securities.

(iv)                               For any matter described in this Section 5.14(c)  in which the Class C Preferred Holders are entitled to vote as a class (whether separately or together with the holders of any Class C Parity Securities), such Class C Preferred Holders shall be entitled to one vote per Class C Preferred Unit. Any Class C Preferred Units held by the Partnership or any of its Subsidiaries or their controlled Affiliates shall not be entitled to vote.

(d)                                  Optional Redemption .

(i)                                      The Partnership shall have the right (A) at any time, and from time to time, on or after April 15, 2024, or (B) at any time within 120 days after the first date on which a Class C Change of Control occurs (the “ Class C Change of Control Redemption Period ”), in each case, to redeem the Class C Preferred Units, which redemption may be in whole or in part, using any source of funds legally available for such purpose. Any such redemption shall occur on a date set by the General Partner (the “ Class C Redemption Date ”). The Partnership shall effect any such redemption by paying cash for each Class C Preferred Unit to be redeemed equal to the Class C Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class C Redemption Date. So long as the Class C Preferred Units to be redeemed are held of record by the nominee of the Class C Securities Depositary, the Class C Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class C Redemption Date shall be paid by the Paying Agent to the Class C Securities Depositary on the Class C Redemption Date.

(ii)                                   The Partnership shall give written notice of any redemption by mail, postage prepaid, not less than 30 days and not more than 60 days before the scheduled Class C Redemption Date, to the Class C Preferred Holders (as of 5:00 p.m. (New York City time) on the Business Day next preceding the day on which notice is given) of any

80

Class C Preferred Units to be redeemed as such Class C Preferred Holders’ names appear on the Partnership’s unit transfer books maintained by the registrar and Transfer Agent and at the address of such Class C Preferred Holders shown therein. Such notice (the “ Class C Redemption Notice ”) shall state, as applicable:  (A) the Class C Redemption Date, (B) the number of Class C Preferred Units to be redeemed and, if less than all Outstanding Class C Preferred Units are to be redeemed, the number (and, in the case of Class C Preferred Units in certificated form, the identification) of Class C Preferred Units to be redeemed from such Class C Preferred Holder, (C) the Class C Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class C Redemption Date, (D) the place where any Class C Preferred Units in certificated form are to be redeemed and shall be presented and surrendered for payment of the Class C Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class C Redemption Date, therefor and (E) that Class C Preferred Unit Distributions on the Class C Preferred Units to be redeemed shall cease to accumulate from and after such Class C Redemption Date.

(iii)                                If the Partnership elects to redeem fewer than all of the Outstanding Class C Preferred Units, the number of Class C Preferred Units to be redeemed shall be determined by the General Partner, and such Class C Preferred Units shall be redeemed by such method of selection as the Class C Securities Depositary shall determine, either Pro Rata or by lot, with adjustments to avoid redemption of fractional Class C Preferred Units. The aggregate Class C Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class C Redemption Date for any such partial redemption of the Outstanding Class C Preferred Units shall be allocated correspondingly among the redeemed Class C Preferred Units. The Class C Preferred Units not redeemed shall remain Outstanding and entitled to all the rights and preferences provided in this Section 5.14 .

(iv)                               If the Partnership gives or causes to be given a Class C Redemption Notice, then the Partnership shall deposit with the Paying Agent funds sufficient to redeem the Class C Preferred Units as to which such Class C Redemption Notice shall have been given by no later than 10:00 a.m. (New York City time) on the Class C Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Class C Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class C Redemption Date, to the Class C Preferred Holders whose Class C Preferred Units are to be redeemed upon surrender or deemed surrender (which shall occur automatically if the Certificate representing such Class C Preferred Units is issued in the name of the Class C Securities Depositary or its nominee) of the Certificates therefor as set forth in the Class C Redemption Notice. If the Class C Redemption Notice shall have been given, then from and after the Class C Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Class C Redemption Notice, all Class C Preferred Unit Distributions on such Class C Preferred Units to be redeemed shall cease to accumulate and all rights of Class C Preferred Holders of such Class C Preferred Units as Limited Partners with respect to such Class C Preferred Units shall cease, except the right to receive the Class C

81

Redemption Price, plus an amount equal to all accumulated and unpaid distributions thereon to, but not including, the applicable Class C Redemption Date, regardless of whether declared, and such Class C Preferred Units shall not thereafter be transferred on the Partnership’s unit transfer books maintained by the registrar and Transfer Agent or be deemed to be Outstanding for any purpose whatsoever. The Class C Preferred Holders shall have no claim to the interest income, if any, earned on such funds deposited with the Paying Agent. Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including, but not limited to, redemption of Class C Preferred Units, that remain unclaimed or unpaid one year after the applicable Class C Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment, the Class C Preferred Holders entitled to such redemption or other payment shall have recourse only to the Partnership. Notwithstanding any Class C Redemption Notice, there shall be no redemption of any Class C Preferred Units called for redemption until funds sufficient to pay the full Class C Redemption Price of such Class C Preferred Units, plus all accumulated and unpaid Class C Preferred Unit Distributions to, but not including, the applicable Class C Redemption Date, regardless of whether declared, shall have been deposited by the Partnership with the Paying Agent.

(v)                                  Any Class C Preferred Units that are redeemed or otherwise acquired by the Partnership shall be cancelled. If only a portion of the Class C Preferred Units represented by a Certificate shall have been called for redemption, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Class C Preferred Units is registered in the name of the Class C Securities Depositary or its nominee), the Partnership shall issue and the Paying Agent shall deliver to such Class C Preferred Holder a new Certificate (or adjust the applicable book-entry account) representing the number of Class C Preferred Units represented by the surrendered Certificate that have not been called for redemption.

(vi)                               Notwithstanding anything to the contrary in this Section 5.14 , in the event that full cumulative distributions on the Class C Preferred Units and any Class C Parity Securities shall not have been paid or declared and set aside for payment, the Partnership shall not be permitted to repurchase, redeem or otherwise acquire, in whole or in part, any Class C Preferred Units or Class C Parity Securities except pursuant to a purchase or exchange offer made on the same relative terms to all Class C Preferred Holders and holders of any Class C Parity Securities. Subject to Section 4.10 , so long as any Class C Preferred Units are Outstanding, the Partnership shall not be permitted to redeem, repurchase or otherwise acquire any Common Units or any other Class C Junior Securities unless full cumulative distributions on the Class C Preferred Units and any Class C Parity Securities for all prior and the then-ending Class C Distribution Periods, with respect to the Class C Preferred Units, and all prior and then-ending distribution periods, with respect to such Class C Parity Securities, shall have been paid or declared and set aside for payment.

82

(e)                                   Change of Control Conversion .

(i)                                      Upon the occurrence of a Class C Change of Control, each Class C Preferred Holder shall have the right (“ Class C Change of Control Conversion Right ”) to convert some or all of the Class C Preferred Units held by such Class C Preferred Holder on the Class C Change of Control Conversion Date into a number of Common Units per Class C Preferred Unit to be converted that is equal to the Class C Conversion Rate (such number of Common Units, the “ Class C Common Unit Conversion Consideration ”), unless the Partnership provides notice of its election to redeem Class C Preferred Units pursuant to Section 5.14(d)(i)(B)  prior to the expiration of the Class C Change of Control Redemption Period.

(ii)                                   Within five days following the expiration of the Class C Change of Control Redemption Period or, if earlier waived, the date of the Partnership’s waiver of its redemption right set forth in Section 5.14(d)(i)(B) , the Partnership will provide to the Class C Preferred Holders written notice (the “ Class C Conversion Notice ”) of the occurrence of the Class C Change of Control that describes the Class C Change of Control Conversion Right and states: (A) the events constituting the Class C Change of Control; (B) the date of the Class C Change of Control; (C) the date on which the Class C Change of Control Redemption Period expired or was waived; (D) the Class C Change of Control Conversion Date; (E) the last date on which the Class C Preferred Holders may exercise their Class C Change of Control Conversion Right; (F) the method and period for calculating the Common Unit Price with respect to the Class C Preferred Units; (G) if applicable, the type and amount of Class C Alternative Conversion Consideration entitled to be received per Class C Preferred Unit; (H) the name and address of the Paying Agent; and (I) the procedure that the Class C Preferred Holders must follow to exercise the Class C Change of Control Conversion Right.

(iii)                                In the case of a Class C Change of Control pursuant to which Common Units will be converted into cash, securities or other property or assets (including any combination thereof) (“ Class C Alternative Conversion Consideration ”), each Class C Preferred Holder electing to exercise its Class C Change of Control Conversion Right will receive upon conversion of the Class C Preferred Units elected by such Class C Preferred Holder the kind and amount of such Class C Alternative Conversion Consideration on a per Class C Preferred Unit basis that such Class C Preferred Holder would have owned or been entitled to receive upon the Class C Change of Control had such Class C Preferred Holder held a number of Common Units equal to the Class C Common Unit Conversion Consideration immediately prior to the effective time of the Class C Change of Control; provided , however, that, if the holders of Common Units have the opportunity to elect the form of consideration to be received in such Class C Change of Control, the consideration that the Class C Preferred Holders electing to exercise their Class C Change of Control Conversion Right will receive will be the form and proportion of the aggregate consideration elected by the holders of Common Units who participate in the determination (based on the weighted average of elections) and will be subject to any limitations to which all holders of Common Units are subject, including, without limitation, pro rata reductions applicable to any portion of the consideration payable in the Class C Change of Control. The Partnership shall pay the cash value in lieu of issuing any fractional Common Units upon the conversion of the Class C Preferred Units.

83

(iv)                               Notwithstanding anything to the contrary in this Agreement, if prior to the expiration of the Class C Change of Control Redemption Period, the Partnership provides notice of its election to redeem Class C Preferred Units pursuant to Section 5.14(d)(i) , Class C Preferred Holders shall not have any right to convert (including pursuant to the Class C Change of Control Conversion Right) the Class C Preferred Units that the Partnership has elected to redeem, and any Class C Preferred Units subsequently selected for redemption that have been tendered for conversion pursuant to the Class C Change of Control Conversion Right shall be redeemed on the applicable Class C Redemption Date instead of converted on the Class C Change of Control Conversion Date.

(v)                                  Notwithstanding anything to the contrary in this Agreement, if prior to the Class C Change of Control Conversion Date, the Partnership provides notice of its election to redeem Class C Preferred Units pursuant to Section 5.14(d)(i) , Class C Preferred Holders of such Class C Preferred Units shall not have any right to convert (including pursuant to the Class C Change of Control Conversion Right) the Class C Preferred Units that the Partnership has elected to redeem, and any Class C Preferred Units subsequently selected for redemption that have been tendered for conversion pursuant to the Class C Change of Control Conversion Right shall be redeemed on the applicable Class C Redemption Date instead of converted on the Class C Change of Control Conversion Date.

(vi)                               The Partnership shall issue a press release for publication through a news or press organization as is reasonably expected to broadly disseminate the relevant information to the public, or post notice on the website of the Partnership, in any event prior to the opening of business on the first Business Day following any date on which the Partnership provides the Class C Conversion Notice to the Class C Preferred Holders.

(vii)                            Each Class C Preferred Holder electing to exercise its Class C Change of Control Conversion Right will be required prior to the close of business on the third Business Day preceding the Class C Change of Control Conversion Date, to notify the Partnership of the number of Class C Preferred Units to be converted pursuant to the Class C Change of Control Conversion Right and otherwise to comply with any applicable procedures contained in the Class C Conversion Notice or otherwise required by the Class C Securities Depositary for effecting the conversion.

(viii)                         Upon conversion, the rights of each participating Class C Preferred Holder, as a holder of the Class C Preferred Units, shall cease with respect to such converted Class C Preferred Units, and each such Person shall continue to be a Partner and have the rights of a holder of Common Units under this Agreement in respect of the Common Units constituting the Class C Conversion Common Units to be issued to such Person in respect of the converted Class C Preferred Units. Each Class C Preferred Unit shall, upon its Class C Change of Control Conversion Date, be deemed to be transferred to, and cancelled by, the Partnership in exchange for the issuance of the Class C Conversion Common Units.

(ix)                               The Partnership shall pay any documentary, stamp or similar issue or transfer taxes or duties relating to the issuance or delivery of Class C Conversion

84

Common Units. However, the participating Class C Preferred Holder shall pay any tax or duty that may be payable relating to any transfer involving the issuance or delivery of Class C Conversion Common Units in a name other than such Class C Preferred Holder’s name. The Transfer Agent may refuse to reflect the notation of book entry (or the issuance of a Certificate) for Common Units being issued in a name other than the Class C Preferred Holder’s name until the Transfer Agent receives a sum sufficient to pay any tax or duties that will be due because the Common Units are to be issued in a name other than the Class C Preferred Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation.

(x)                                  The Partnership shall comply with all applicable securities laws regulating the offer and delivery of any Class C Conversion Common Units and, if the Common Units are then listed or quoted on a National Securities Exchange or other market, shall list or cause to have quoted and keep listed and quoted the Class C Conversion Common Units to the extent permitted or required by the rules of such exchange or market.

(xi)                               Notwithstanding anything herein to the contrary, nothing herein shall give to any Class C Preferred Holder any rights as a creditor in respect of its right to conversion of Class C Preferred Units.

(f)                                    Record Holders .  To the fullest extent permitted by applicable law, the General Partner, the Partnership, the Transfer Agent and the Paying Agent may deem and treat any Class C Preferred Holder as the true, lawful and absolute owner of the applicable Class C Preferred Units for all purposes, and neither the General Partner, the Partnership nor the Transfer Agent or the Paying Agent shall be affected by any notice to the contrary, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Class C Preferred Units are listed or admitted to trading.

(g)                                   Notices .  All notices or communications in respect of the Class C Preferred Units shall be sufficiently given if given in writing and delivered in person or by first class mail, postage prepaid, or if given in such other manner as may be permitted in this Section 5.14 , this Agreement or by applicable law.

(h)                                  Other Rights; Fiduciary Duties .  The Class C Preferred Units and the Class C Preferred Holders shall not have any designations, preferences, rights, powers or duties, other than as set forth in this Agreement or as provided by applicable law. Notwithstanding anything to the contrary in this Agreement or any duty existing at law, in equity or otherwise, to the fullest extent permitted by applicable law, neither the General Partner nor any other Indemnitee shall owe any duties, including fiduciary duties, or have any liabilities to Class C Preferred Holders, other than the implied contractual covenant of good faith and fair dealing.

87

(F)                                  Finally, (x) to the General Partner in accordance with its Percentage Interest, (y) 48% to the holders of the Incentive Distribution Rights, Pro Rata, and (z) to all Unitholders (other than Preferred Holders with respect to their Preferred Units), Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (x) and (y) of this clause (G).

(ii)                                   Net Termination Loss (including a Pro Rata part of each item of income, gain, loss, and deduction taken into account in computing Net Termination Loss) shall be allocated:

(A)                                First , to the General Partner and the Unitholders (other than Preferred Holders with respect to their Preferred Units), Pro Rata, until the Adjusted Capital Account in respect of each Common Unit then Outstanding has been reduced to zero;

(B)                                Second , to all Preferred Holders, in proportion to their respective positive Adjusted Capital Account balances, until the Adjusted Capital Account in respect of each Preferred Unit then Outstanding has been reduced to zero;

(C)                                The balance , if any, 100% to the General Partner.

(d)                                  Special Allocations .  Notwithstanding any other provision of this Section 6.1 , the following special allocations shall be made for such taxable period:

(i)                                      Partnership Minimum Gain Chargeback .  Notwithstanding any other provision of this Section 6.1 , if there is a net decrease in Partnership Minimum Gain during any Partnership taxable period, each Partner shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6), 1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provision. For purposes of this Section 6.1(d) , each Partner’s Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d)  with respect to such taxable period (other than an allocation pursuant to Section 6.1(d)(vi)  and Section 6.1(d)(vii) ). This Section 6.1(d)(i)  is intended to comply with the Partnership Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(ii)                                   Chargeback of Partner Nonrecourse Debt Minimum Gain .  Notwithstanding the other provisions of this Section 6.1 (other than Section 6.1(d)(i) ), except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any Partnership taxable period, any Partner with a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section 6.1(d) , each Partner’s Adjusted Capital Account

88

balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d) , other than Section 6.1(d)(i)  and other than an allocation pursuant to Section 6.1(d)(vi)  and Section 6.1(d)(vii) , with respect to such taxable period. This Section 6.1(d)(ii)  is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(iii)                                Priority Allocations .

(A)                                If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Section 12.4 ) with respect to a Unit exceeds the amount of cash or the Net Agreed Value of property distributed with respect to another Unit (the amount of the excess, an “ Excess Distribution ” and the Unit with respect to which the greater distribution is paid, an “ Excess Distribution Unit ”), then (1) there shall be allocated gross income and gain to each Unitholder receiving an Excess Distribution with respect to the Excess Distribution Unit until the aggregate amount of such items allocated with respect to such Excess Distribution Unit pursuant to this Section 6.1(d)(iii)(A)  for the current taxable period and all previous taxable periods is equal to the amount of the Excess Distribution; and (2) the General Partner shall be allocated gross income and gain with respect to each such Excess Distribution in an amount equal to the product obtained by multiplying (x) the quotient determined by dividing (aa) the General Partner’s Percentage Interest at the time when the Excess Distribution occurs by (bb) a percentage equal to 100% less the General Partner’s Percentage Interest at the time when the Excess Distribution occurs, times (y) the total amount allocated in clause (1) above with respect to such Excess Distribution; provided , however, this Section 6.1(d)(iii)(A)  shall not apply to any Excess Distribution in respect to or measured by a distribution with respect to a Preferred Unit and shall not apply to the extent distributions are not made with respect to a Deemed Warrant Unit with respect to any Record Date prior to the Vesting Date of such Deemed Warrant Unit.

(B)                                After the application of Section 6.1(d)(iii)(A) , all or any portion of the remaining items of Partnership gross income or gain for the taxable period, if any, shall be allocated (1) to the holders of Incentive Distribution Rights, Pro Rata, until the aggregate amount of such items allocated to the holders of Incentive Distribution Rights pursuant to this Section 6.1(d)(iii)(B)  for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Incentive Distributions made to the holders of Incentive Distribution Rights from the Closing Date to a date 45 days after the end of the current taxable period; and (2) to the General Partner an amount equal to the product of (x) an amount equal to the quotient determined by dividing (aa) the General Partner’s Percentage Interest by (bb) the sum of 100 less the General Partner’s Percentage Interest times (y) the sum of the amounts allocated in clause (1) above.

89

(iv)                               Qualified Income Offset .  In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of Partnership gross income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible; provided, that an allocation pursuant to this Section 6.1(d)(iv)  shall be made only if and to the extent that such Partner would have a deficit balance in its Adjusted Capital Account as adjusted after all other allocations provided for in this Section 6.1 have been tentatively made as if this Section 6.1(d)(iv)  were not in this Agreement.

(v)                                  Gross Income Allocation .  In the event any Partner has a deficit balance in its Capital Account at the end of any taxable period in excess of the sum of (A) the amount such Partner is required to restore pursuant to the provisions of this Agreement and (B) the amount such Partner is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Partner shall be specially allocated items of Partnership gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 6.1(d)(v)  shall be made only if and to the extent that such Partner would have a deficit balance in its Capital Account as adjusted after all other allocations provided for in this Section 6.1 have been tentatively made as if Section 6.1(d)(iv)  and this Section 6.1(d)(v)  were not in this Agreement.

(vi)                               Nonrecourse Deductions .  Nonrecourse Deductions for any taxable period shall be allocated to the Partners Pro Rata. If the General Partner determines that the Partnership’s Nonrecourse Deductions should be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations promulgated under Section 704(b) of the Code, the General Partner is authorized, upon notice to the other Partners, to revise the prescribed ratio to the numerically closest ratio that does satisfy such requirements.

(vii)                            Partner Nonrecourse Deductions .  Partner Nonrecourse Deductions for any taxable period shall be allocated 100% to the Partner that bears the Economic Risk of Loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Partner bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, such Partner Nonrecourse Deductions attributable thereto shall be allocated between or among such Partners in accordance with the ratios in which they share such Economic Risk of Loss.

(viii)                         Nonrecourse Liabilities .  For purposes of Treasury Regulation Section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of the Partnership in excess of the sum of (A) the amount of Partnership Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated among the Partners Pro Rata.

90

(ix)                               Code Section 754 Adjustments .  To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations.

(x)                                  Economic Uniformity; Changes in Law .

(A)                                [Reserved].

(B)                                With respect to an event triggering an adjustment to the Carrying Value of Partnership property pursuant to Section 5.5(d)  during any taxable period of the Partnership ending upon, or after, the issuance of IDR Reset Common Units pursuant to Section 5.11 , after the application of Section 6.1(d)(x)(A) , any Unrealized Gains and Unrealized Losses shall be allocated among the Partners in a manner that to the nearest extent possible results in the Capital Accounts maintained with respect to such IDR Reset Common Units issued pursuant to Section 5.11 equaling the product of (1) the Aggregate Quantity of IDR Reset Common Units and (2) the Per Unit Capital Amount for an Initial Common Unit.

(C)                                With respect to any taxable period during which an IDR Reset Unit is transferred to any Person who is not an Affiliate of the transferor, all or a portion of the remaining items of Partnership gross income or gain for such taxable period shall be allocated 100% to the transferor Partner of such transferred IDR Reset Common Unit until such transferor Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such transferred IDR Reset Unit to an amount equal to the Per Unit Capital Amount for an Initial Common Unit.

(D)                                For the proper administration of the Partnership and for the preservation of uniformity of the Limited Partner Interests (or any class or classes thereof), the General Partner shall (1) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; (2) make special allocations of income, gain, loss, deduction, Unrealized Gain or Unrealized Loss; and (3) amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code or (y) otherwise to preserve or achieve uniformity of the Limited Partner Interests (or any class or classes thereof). The General Partner may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 6.1(d)(x)(D)  only if such conventions, allocations or amendments would not have a material adverse effect on the Partners, the holders of any class

91

or classes of Limited Partner Interests issued and Outstanding or the Partnership, and if such allocations are consistent with the principles of Section 704 of the Code.

(xi)                               Curative Allocation .

(A)                                Notwithstanding any other provision of this Section 6.1 , other than the Required Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of gross income, gain, loss and deduction allocated to each Partner pursuant to the Required Allocations and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Partner under the Agreed Allocations had the Required Allocations and the related Curative Allocation not otherwise been provided in this Section 6.1 . In exercising its discretion under this Section 6.1(d)(xi)(A) , the General Partner may take into account future Required Allocations that, although not yet made, are likely to offset other Required Allocations previously made. Allocations pursuant to this Section 6.1(d)(xi)(A)  shall only be made with respect to Required Allocations to the extent the General Partner determines that such allocations will otherwise be inconsistent with the economic agreement among the Partners.

(B)                                The General Partner shall, with respect to each taxable period, (1) apply the provisions of Section 6.1(d)(xi)(A)  in whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Section 6.1(d)(xi)(A)  among the Partners in a manner that is likely to minimize such economic distortions.

(xii)                            Corrective and Other Allocations .  In the event of any allocation of Additional Book Basis Derivative Items or any Book-Down Event or any recognition of a Net Termination Loss, the following rules shall apply:

(A)                                Except as provided in Section 6.1(d)(xii)(B) , in the case of any allocation of Additional Book Basis Derivative Items (other than an allocation of Unrealized Gain or Unrealized Loss under Section 5.5(d)  hereof), the General Partner shall allocate such Additional Book Basis Derivative Items to (1) the holders of Incentive Distribution Rights and the General Partner to the same extent that the Unrealized Gain or Unrealized Loss giving rise to such Additional Book Basis Derivative Items was allocated to them pursuant to Section 5.5(d)  and (2) all Unitholders, Pro Rata, to the extent that the Unrealized Gain or Unrealized Loss giving rise to such Additional Book Basis Derivative Items was allocated to any Unitholders pursuant to Section 5.5(d) .

(B)                                In the case of any allocation of Additional Book Basis Derivative Items (other than an allocation of Unrealized Gain or Unrealized Loss under Section 5.5(d)  hereof or an allocation of Net Termination Gain or Net Termination Loss pursuant to Section 6.1(c)  hereof) as a result of a sale or other taxable disposition of any Partnership asset that is an Adjusted Property

92

(“ Disposed of Adjusted Property ”), the General Partner shall allocate (1) additional items of gross income and gain (x) away from the holders of Incentive Distribution Rights and (y) to the Unitholders, or (2) additional items of deduction and loss (x) away from the Unitholders and (y) to the holders of Incentive Distribution Rights, to the extent that the Additional Book Basis Derivative Items allocated to the Unitholders exceed their Share of Additional Book Basis Derivative Items with respect to such Disposed of Adjusted Property. Any allocation made pursuant to this Section 6.1(d)(xii)(B)  shall be made after all of the other Agreed Allocations have been made as if this Section 6.1(d)(xii)  were not in this Agreement and, to the extent necessary, shall require the reallocation of items that have been allocated pursuant to such other Agreed Allocations.

(C)                                In the case of any negative adjustments to the Capital Accounts of the Partners resulting from a Book-Down Event or from the recognition of a Net Termination Loss, such negative adjustment (1) shall first be allocated, to the extent of the Aggregate Remaining Net Positive Adjustments, in such a manner, as determined by the General Partner, that to the extent possible the aggregate Capital Accounts of the Partners will equal the amount that would have been the Capital Account balances of the Partners if no prior Book-Up Events had occurred, and (2) any negative adjustment in excess of the Aggregate Remaining Net Positive Adjustments shall be allocated pursuant to Section 6.1(c)  hereof.

(D)                                For purposes of this Section 6.1(d)(xii) , the Unitholders shall be treated as being allocated Additional Book Basis Derivative Items to the extent that such Additional Book Basis Derivative Items have reduced the amount of income that would otherwise have been allocated to the Unitholders under this Agreement. In making the allocations required under this Section 6.1(d)(xii) , the General Partner may apply whatever conventions or other methodology it determines will satisfy the purpose of this Section 6.1(d)(xii) . Without limiting the foregoing, if an Adjusted Property is contributed by the Partnership to another entity classified as a partnership for federal income tax purposes (the “ lower tier partnership ”), the General Partner may make allocations similar to those described in Section 6.1(d)(xii)(A)  — Section 6.1(d)(xii)(C)  to the extent the General Partner determines such allocations are necessary to account for the Partnership’s allocable share of income, gain, loss and deduction of the lower tier partnership that relate to the contributed Adjusted Property in a manner that is consistent with the purpose of this Section 6.1(d)(xii) .

(E)                                 Notwithstanding any other provision of this Section 6.1(d)(xii), (1) no allocations shall be made pursuant to this Section 6.1(d)(xii) with respect to any taxable period (or portion thereof) ending on or prior to the Closing Date and (2) for taxable periods (or portions thereof) ending after the Closing Date, the determinations of Additional Book Basis (and items derived therefrom) and Net Positive Adjustments (and items derived therefrom) shall be made without regard to any Book-Up Event or Book-Down Event that occurred on or prior to the Closing Date.

93

(xiii)                         Allocations with respect to Class A Preferred Units .

(A)                                Items of Partnership gross income shall be allocated to the Class A Preferred Holders, Pro Rata, until the aggregate amount of gross income allocated to each Class A Preferred Holder pursuant hereto for the current and all previous taxable periods is equal to the cumulative Class A Preferred Unit Distribution Amount in respect of such Class A Preferred Holder’s Class A Preferred Units with respect to the current and all prior taxable periods; provided that gross income shall not be allocated pursuant to this Section 6.1(d)(xiii)(A)  to the extent such allocation would cause the Per Unit Capital Account of a Class A Preferred Unit to exceed the Class A Liquidation Preference; and provided , further , that the allocations to a Class A Preferred Holder under this Section 6.1(d)(xiii)(A)  shall be reduced to the extent Class A Preferred Unit Distributions are properly treated as guaranteed payments under Section 707(c) of the Code or payments to such Class A Preferred Holder other than in its capacity as a partner pursuant to Section 707(a) of the Code.

(B)                                Items of Partnership gross income shall be allocated to the Class A Preferred Holders, Pro Rata, until the aggregate amount of gross income allocated to each Class A Preferred Holder pursuant hereto for the current and all prior taxable periods is equal to the cumulative amount of all Net Losses allocated to such Class A Preferred Holder pursuant to Section 6.1(b)(ii)  for all previous taxable periods; provided that gross income shall not be allocated pursuant to this Section 6.1(d)(xiii)(B)  to the extent such allocation would cause the Per Unit Capital Account of a Class A Preferred Unit to exceed the Class A Liquidation Preference.

(C)                                To the extent the Per Unit Capital Account of each Class A Preferred Unit is less than the Class A Liquidation Preference, income and gain resulting from a Book-up Event shall be allocated to the holders of Class A Preferred Units, until the Per Unit Capital Account of each Class A Preferred Unit is equal to the Class A Liquidation Preference.

(D)                                Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations), if (1) the Liquidation Date occurs prior to the conversion of the last Outstanding Class A Preferred Unit and (2) after having made all other allocations provided for in this Section 6.1 (other than the allocations provided for in Section 6.1(d)(xv)(B)  and Section 6.1(d)(xvi)(B) , if any, which shall be made simultaneously with the allocations in this Section 6.1(d)(xiii)(D) ) for the taxable period in which the Liquidation Date occurs, the Per Unit Capital Amount of each Class A Preferred Unit does not equal the Class A Liquidation Preference, then items of income, gain, loss and deduction for such taxable period shall be allocated among the Partners in a manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Per Unit Capital Amount in respect of each Class A Preferred Unit to equal the Class A Liquidation Preference. For the avoidance of doubt, the reallocation of items set forth in the immediately preceding sentence provides

94

that, to the extent necessary to achieve the Per Unit Capital Amount balances described above, items of income and gain that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs, shall be reallocated from the Unitholders holding Units other than Class A Preferred Units to Unitholders holding Class A Preferred Units. In the event that (1) the Liquidation Date occurs on or before the date (not including any extension of time) prescribed by law for the filing of the Partnership’s federal income tax return for the taxable period immediately prior to the taxable period in which the Liquidation Date occurs and (2) the reallocation of items for the taxable period in which the Liquidation Date occurs as set forth above in this Section 6.1(d)(xiii)(D)  fails to achieve the Per Unit Capital Amounts described above, items of income, gain, loss and deduction that would otherwise be included in the Net Income or Net Loss, as the case may be, for such prior taxable period shall be reallocated among all Partners in a manner that will, to the maximum extent possible and after taking into account all other allocations made pursuant to this Section 6.1(d)(xiii)(D) , cause the Per Unit Capital Amount in respect of each Class A Preferred Unit to equal the Class A Liquidation Preference.

(xiv)                        Deemed Warrant Units .  Following each Vesting Date, to the extent the Per Unit Capital Account attributable to any Deemed Warrant Unit for which a Vesting Date has occurred is less than the Per Unit Capital Account of a Common Unit:

(A)                                Items of Partnership gross income, gain, loss and deduction resulting from a Book-Up Event or a Book-Down Event shall be allocated to the holders of Deemed Warrant Units and Common Units as necessary, to cause, to the extent possible, the Per Unit Capital Account attributable to any Deemed Warrant Units for which a Vesting Date has occurred to equal the Per Unit Capital Account of a Common Unit.

(B)                                With respect to any taxable period in which the Vesting Date occurs (and if necessary subsequent tax periods), to the extent the Per Unit Capital Account of the Deemed Warrant Unit for which a Vesting Date occurs is not equivalent to the Per Unit Capital Amount of a Common Unit after application of Section 6.1(d)(xiv)(A) , items of Partnership gross income, gain, deduction or loss for the taxable period shall be allocated 100% to each holder of Deemed Warrant Units for which a Vesting Date occurs in the proportion that the respective number of Deemed Warrant Units for which a Vesting Date occurs held by such holder bears to the total number of Deemed Warrant Units for which a Vesting Date occurs, until each such holder has been allocated an amount of gross income, gain, deduction or loss with respect to such Deemed Warrant Units for which a Vesting Date has occurred that causes the Capital Account attributable to each Deemed Warrant Unit, on a per Unit basis, to equal the Per Unit Capital Amount for a Common Unit on the Vesting Date. The purpose for this allocation is to establish uniformity between the Capital Accounts underlying Deemed Warrant Units for which a Vesting Date occurs and the Capital Accounts underlying Common Units immediately prior to the Vesting Date.

95

(C)                                If a holder of Deemed Warrant Units or Common Units granted upon exercise of the Deemed Warrant Units has a remaining Capital Account remaining after the disposing of all such Deemed Warrant Units or Common Units pursuant to Section 5.5(c)(iii)  or in the event a Deemed Warrant Unit is not exercised, such holder shall be allocated items of loss and deduction equal to such remaining balance.

(xv)                           Allocations with Respect to Class B Preferred Units .

(A)                                Items of income or gain for each taxable period shall be allocated to each holder of Class B Preferred Units, in proportion to, and to the extent of, an amount equal to the excess, if any, of (1) the Class B Stated Liquidation Preference with respect to such holder’s Class B Preferred Units, over (2) such holder’s existing Capital Account balance in respect of such Class B Preferred Units, until the Capital Account balance of each such holder in respect of its Class B Preferred Units is equal to the Class B Stated Liquidation Preference with respect to such holder’s Class B Preferred Units.

(B)                                Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations), if (1) the Liquidation Date occurs prior to the conversion of the last Outstanding Class B Preferred Unit and (2) after having made all other allocations provided for in this Section 6.1 (other than the allocations provided for in Section 6.1(d)(xiii)(D)  and Section 6.1(d)(xvi)(B) , if any, which shall be made simultaneously with the allocations in this Section 6.1(d)(xv)(B) ) for the taxable period in which the Liquidation Date occurs, the Per Unit Capital Amount of each Class B Preferred Unit does not equal the Class B Stated Liquidation Preference, then items of income, gain, loss and deduction for such taxable period shall be allocated among the Partners in a manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Per Unit Capital Amount in respect of each Class B Preferred Unit to equal the Class B Stated Liquidation Preference. For the avoidance of doubt, the reallocation of items set forth in the immediately preceding sentence provides that, to the extent necessary to achieve the Per Unit Capital Amount balances described above, items of income and gain that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs, shall be reallocated from the Unitholders holding Units other than Class B Preferred Units to Unitholders holding Class B Preferred Units. In the event that (1) the Liquidation Date occurs on or before the date (not including any extension of time) prescribed by law for the filing of the Partnership’s federal income tax return for the taxable period immediately prior to the taxable period in which the Liquidation Date occurs and (2) the reallocation of items for the taxable period in which the Liquidation Date occurs as set forth above in this Section 6.1(d)(xv)(B)  fails to achieve the Per Unit Capital Amounts described above, items of income, gain, loss and deduction that would otherwise be included in the Net Income or Net Loss, as the case may be, for such prior taxable period shall be reallocated among all Partners in a manner that will, to the maximum extent possible and after taking into account all other allocations made

96

pursuant to this Section 6.1(d)(xv)(B) , cause the Per Unit Capital Amount in respect of each Class B Preferred Unit to equal the Class B Stated Liquidation Preference.

(xvi)                        Allocations with Respect to Class C Preferred Units .

(A)                                Items of income or gain for each taxable period shall be allocated to each holder of Class C Preferred Units, in proportion to, and to the extent of, an amount equal to the excess, if any, of (1) the Class C Stated Liquidation Preference with respect to such holder’s Class C Preferred Units, over (2) such holder’s existing Capital Account balance in respect of such Class C Preferred Units, until the Capital Account balance of each such holder in respect of its Class C Preferred Units is equal to the Class C Stated Liquidation Preference with respect to such holder’s Class C Preferred Units.

(B)                                Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations), if (1) the Liquidation Date occurs prior to the conversion of the last Outstanding Class C Preferred Unit and (2) after having made all other allocations provided for in this Section 6.1 (other than the allocations provided for in Section 6.1(d)(xiii)(D)  and Section 6.1(d)(xv)(B) , if any, which shall be made simultaneously with the allocations in this Section 6.1(d)(xvi)(B) ) for the taxable period in which the Liquidation Date occurs, the Per Unit Capital Amount of each Class C Preferred Unit does not equal the Class C Stated Liquidation Preference, then items of income, gain, loss and deduction for such taxable period shall be allocated among the Partners in a manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Per Unit Capital Amount in respect of each Class C Preferred Unit to equal the Class C Stated Liquidation Preference. For the avoidance of doubt, the reallocation of items set forth in the immediately preceding sentence provides that, to the extent necessary to achieve the Per Unit Capital Amount balances described above, items of income and gain that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs, shall be reallocated from the Unitholders holding Units other than Class C Preferred Units to Unitholders holding Class C Preferred Units. In the event that (1) the Liquidation Date occurs on or before the date (not including any extension of time) prescribed by law for the filing of the Partnership’s federal income tax return for the taxable period immediately prior to the taxable period in which the Liquidation Date occurs and (2) the reallocation of items for the taxable period in which the Liquidation Date occurs as set forth above in this Section 6.1(d)(xvi)(B)  fails to achieve the Per Unit Capital Amounts described above, items of income, gain, loss and deduction that would otherwise be included in the Net Income or Net Loss, as the case may be, for such prior taxable period shall be reallocated among all Partners in a manner that will, to the maximum extent possible and after taking into account all other allocations made pursuant to this Section 6.1(d)(xvi)(B) , cause the Per Unit Capital Amount in respect of each Class C Preferred Unit to equal the Class C Stated Liquidation Preference.

Section 6.2                                    Allocations for Tax Purposes .

(a)                                  Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Partners in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 6.1 .

(b)                                  In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, depreciation, amortization and cost recovery deductions shall be allocated for federal income tax purposes among the Partners in the manner provided under Section 704(c) of the Code, and the Treasury Regulations promulgated under Section 704(b) and 704(c) of the Code, as determined appropriate by the General Partner (taking into account the General Partner’s discretion under Section 6.1(d)(x)(D) ); provided, that the General Partner shall apply the principles of Treasury Regulation Section 1.704-3(d) in all events.

(c)                                   The General Partner may determine to depreciate or amortize the portion of an adjustment under Section 743(b) of the Code attributable to unrealized appreciation in any Adjusted Property (to the extent of the unamortized Book-Tax Disparity) using a predetermined rate derived from the depreciation or amortization method and useful life applied to the unamortized Book-Tax Disparity of such property, despite any inconsistency of such approach with Treasury Regulation Section 1.167(c)-l(a)(6) or any successor regulations thereto. If the General Partner determines that such reporting position cannot reasonably be taken, the General Partner may adopt depreciation and amortization conventions under which all purchasers acquiring Limited Partner Interests in the same month would receive depreciation and amortization deductions, based upon the same applicable rate as if they had purchased a direct interest in the Partnership’s property. If the General Partner chooses not to utilize such aggregate method, the General Partner may use any other depreciation and amortization conventions to preserve the uniformity of the intrinsic tax characteristics of any Limited Partner Interests, so long as such conventions would not have a material adverse effect on the Limited Partners or the Record Holders of any class or classes of Limited Partner Interests.

(d)                                  In accordance with Treasury Regulation Sections 1.1245-1(e) and 1.1250-1(f), any gain allocated to the Partners upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this Section 6.2 , be characterized as Recapture Income in the same proportions and to the same extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income.

(e)                                   All items of income, gain, loss, deduction and credit recognized by the Partnership for federal income tax purposes and allocated to the Partners in accordance with the provisions hereof shall be determined without regard to any election under Section 754 of the Code that may be made by the Partnership; provided , however , that such allocations, once made, shall be adjusted (in the manner determined by the General Partner) to take into account those adjustments permitted or required by Sections 734 and 743 of the Code.

(f)                                    Each item of Partnership income, gain, loss and deduction shall, for federal income tax purposes, be determined for each taxable period and prorated on a monthly basis and

98

shall be allocated to the Partners as of the opening of the National Securities Exchange on which the Partnership Interests are listed or admitted to trading on the first Business Day of each month; provided , however , that gain or loss on a sale or other disposition of any assets of the Partnership or any other extraordinary item of income, gain, loss or deduction as determined by the General Partner, shall be allocated to the Partners as of the opening of the National Securities Exchange on which the Partnership Interests are listed or admitted to trading on the first Business Day of the month in which such item is recognized for federal income tax purposes. The General Partner may revise, alter or otherwise modify such methods of allocation to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder.

(g)                                   Allocations that would otherwise be made to a Limited Partner under the provisions of this Article VI shall instead be made to the beneficial owner of Limited Partner Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method determined by the General Partner.

(h)                                  If, as a result of an exercise of a Noncompensatory Option, a Capital Account reallocation is required under Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), the General Partner shall make corrective allocations pursuant to Treasury Regulation Section 1.704-1(b)(4)(x).

Section 6.3                                    Requirement and Characterization of Distributions; Distributions to Record Holders .

(a)                                  Subject to Section 6.3(b) , within 45 days following the end of each Quarter commencing with the Quarter in which the Closing Date occurred an amount equal to 100% of Available Cash with respect to such Quarter shall be distributed in accordance with this Article VI by the Partnership to Partners as of the Record Date selected by the General Partner. All amounts of Available Cash distributed by the Partnership on any date after the Closing Date from any source shall be deemed to be Operating Surplus until the sum of all amounts of Available Cash theretofore distributed by the Partnership to the Partners pursuant to Section 6.4 equals the Operating Surplus from the Closing Date through the close of the immediately preceding Quarter. Any remaining amounts of Available Cash distributed by the Partnership on such date shall, except as otherwise provided in Section 6.5 , be deemed to be “ Capital Surplus .”

(b)                                  With respect to the distribution for the Quarter in which the Closing Date occurred, the amount of Available Cash distributed to the Partners in accordance with Section 6.3(a)  shall equal 100% of the Available Cash with respect to such Quarter multiplied by a fraction of which the numerator is the number of days in the period commencing on the Closing Date and ending on the last day of the Quarter in which the Closing Date occurred and of which the denominator is the number of days in such Quarter.

(c)                                   Notwithstanding Section 6.3(a) , in the event of the dissolution and liquidation of the Partnership, all cash received during or after the Quarter in which the Liquidation Date occurs, other than from Working Capital Borrowings, shall be applied and distributed solely in accordance with, and subject to the terms and conditions of, Section 12.4 .

99

(d)                                  Each distribution in respect of a Partnership Interest shall be paid by the Partnership, directly or through any Transfer Agent or through any other Person or agent, only to the Record Holder of such Partnership Interest as of the Record Date set for such distribution. Such payment shall constitute full payment and satisfaction of the Partnership’s liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise.

Section 6.4                                    Distributions of Available Cash from Operating Surplus .

Available Cash that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or Section 6.5 shall be distributed as follows, except as otherwise contemplated by Section 5.6(b)  in respect of additional Partnership Interests issued pursuant thereto (including pursuant to Article V with respect to the Preferred Units):

(a)                                  First , 100% to the General Partner and the Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter;

(b)                                  Second , 100% to the General Partner and the Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter;

(c)                                   Third , (i) to the General Partner in accordance with its Percentage Interest; (ii) 13% to the holders of the Incentive Distribution Rights, Pro Rata; and (iii) to all Unitholders, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (i) and (ii) of this clause (c), until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Second Target Distribution over the First Target Distribution for such Quarter;

(d)                                  Fourth , (i) to the General Partner in accordance with its Percentage Interest; (ii) 23% to the holders of the Incentive Distribution Rights, Pro Rata; and (iii) to all Unitholders, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (i) and (ii) of this clause (d), until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Third Target Distribution over the Second Target Distribution for such Quarter; and

(e)                                   Thereafter , (i) to the General Partner in accordance with its Percentage Interest; (ii) 48% to the holders of the Incentive Distribution Rights, Pro Rata; and (iii) to all Unitholders, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (i) and (ii) of this clause (e);

provided, however , if the Minimum Quarterly Distribution, the First Target Distribution, the Second Target Distribution and the Third Target Distribution have been reduced to zero pursuant to the second sentence of Section 6.6(a) , the distribution of Available Cash that is deemed to be Operating Surplus with respect to any Quarter will be made solely in accordance with Section 6.4(e) .

100

Section 6.5                                    Distributions of Available Cash from Capital Surplus .  Available Cash that is deemed to be Capital Surplus pursuant to the provisions of Section 6.3(a)  shall be distributed, unless the provisions of Section 6.3 require otherwise and subject to Article V with respect to the Preferred Units, 100% to the General Partner and the Unitholders, Pro Rata, until the Minimum Quarterly Distribution has been reduced to zero pursuant to the second sentence of Section 6.6(a) . Available Cash that is deemed to be Capital Surplus shall then be distributed to the General Partner in accordance with its Percentage Interest. Thereafter, all Available Cash shall be distributed as if it were Operating Surplus and shall be distributed in accordance with Section 6.4 .

Section 6.6                                    Adjustment of Minimum Quarterly Distribution and Target Distribution Levels .

(a)                                  The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution  and Third Target Distribution shall be proportionately adjusted in the event of any distribution, combination or subdivision (whether effected by a distribution payable in Units or otherwise) of Units or other Partnership Interests in accordance with Section 5.9 . In the event of a distribution of Available Cash that is deemed to be from Capital Surplus, the then applicable Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, shall be reduced in the same proportion that the distribution had to the fair market value of the Common Units immediately prior to the announcement of the distribution. If the Common Units are publicly traded on a National Securities Exchange, the fair market value will be the Current Market Price before the ex-dividend date. If the Common Units are not publicly traded, the fair market value will be determined by the Board of Directors.

(b)                                  The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, shall also be subject to adjustment pursuant to Section 5.11 and Section 6.9 .

Section 6.7                                    Special Provisions Relating to the Holders of Converted Subordinated Units .

(a)                                  Holders of converted Subordinated Units shall possess all of the rights and obligations of a Unitholder holding Common Units hereunder with respect to such converted Subordinated Units, including the right to vote as a Common Unitholder and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units; provided , however , that such converted Subordinated Units shall remain subject to the provisions of Section 5.5(c)(ii) , Section 6.1(d)(x) , Section 6.7(b)  and Section 6.7(c) .

(b)                                  A Unitholder shall not be permitted to transfer a converted Subordinated Unit (other than a transfer to an Affiliate) if the remaining balance in the transferring Unitholder’s Capital Account with respect to the retained converted Subordinated Units would be negative after giving effect to the allocation under Section 5.5(c)(ii) .

(c)                                   The Unitholder holding a converted Subordinated Unit shall not be issued a Common Unit Certificate pursuant to Section 4.1 , if the Common Units are evidenced by Certificates, and shall not be permitted to transfer such Common Unit to a Person that is not an

101

Affiliate of the holder until such time as the General Partner determines, based on advice of counsel, that each such Common Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics, in all material respects, to the intrinsic economic and federal income tax characteristics of an Initial Common Unit. In connection with the condition imposed by this Section 6.7(c) , the General Partner may take whatever steps are required to provide economic uniformity to such Common Units in preparation for a transfer of such Common Units, including the application of Section 5.5(c)(ii) , Section 6.1(d)(x)  and Section 6.7(b) ; provided , however , that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units.
