COVENANTS
Section 5.1    Further Assurances. In case at any time after the Closing any

information as may be reasonably required in connection with any such filings
and otherwise cooperate.
Section 5.3    Tax Treatment of the Transaction. The Parties intend that the
Transaction will be treated for U.S. federal income tax purposes as set forth in

consistent with the Intended Tax Treatment, unless required by Law to do
otherwise.
(a)    The transactions contemplated hereby shall be treated as either (A) a
transaction described in Section 721 of the Internal Revenue Code in a manner

Units, to the extent any gain is recognized as a result of the transactions
contemplated hereby causing a decrease in their share of Partnership liabilities
under Section 752 of the Internal Revenue Code.
(b)    The transactions contemplated hereby should result in an adjustment to
the capital accounts of the Partners and the carrying values of MPLX’s
properties in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f).
Section 5.4    Satisfaction of Conditions Precedent. From the Execution Date

to do all things necessary, proper, or advisable in order to consummate and make
effective the transactions contemplated by this Agreement, including, without
limitation, obtaining any and all necessary local, state, and federal government
approvals with respect to the transactions, if any, and the satisfaction of the
other conditions precedent set forth in ARTICLE VI; provided, however, that no
Party shall be required to take or cause to be taken any action, or to do or
cause to be done anything, this Agreement contemplates to be taken or done, or
caused to be taken or done, by the other Party.
Section 5.5    Notices. Each of the Parties will give prompt notice to the other
of any event or circumstance which has or would be reasonably likely to give
rise to a breach of any representation, warranty or covenant contained in this
Agreement, or of any condition which would reasonably be expected to delay or
prevent the Closing hereunder.
Section 5.6    Certain Business Activities. From the Execution Date until the
Closing and except as contemplated by this Agreement or as required by
applicable Law, without the prior written consent of the other Parties hereto,
neither of the Parties shall, and each shall not take any action to cause any
other Party to, take any action that would be reasonably likely to result in a
Material Adverse Effect on its ability to perform any of its obligations under
this Agreement, including, without limitation, in the case of the General
Partner, transferring the General Partner Units or the Incentive Distribution
Rights.
Section 5.7    Listing of Common Units. The General Partner and MPLX shall use

Common Units to be admitted for listing on the New York Stock Exchange as
promptly as practicable after the Closing Date.

writing and shall in no way adversely affect the rights of the Party granting

1(b)(2)(ii)(c) (or is deemed obligated to restore under Treasury Regulation
Sections 1.704-2(g) and 1.704-2(i)(5)) and (b) decreased by (i) the amount of

Section 1.751-1(b)(2)(ii), and (ii) the amount of all distributions that, as of

Account is intended to comply with the provisions of Treasury Regulation Section

“Adjusted Capital Account” of a Partner in respect of a Series A Preferred Unit,
a Common Unit or any other specified interest in the Partnership shall be the
amount which such Adjusted Capital Account would be if such General Partner
Interest, a Series A Preferred Unit, a Common Unit or other interest in the

each Contributed Property.

credit needs of the Partnership Group) subsequent to such Quarter;

ORGANIZATION
Section 2.1    Formation. The General Partner and the Organizational Limited
Partner have previously formed the Partnership as a limited partnership pursuant
to the provisions of the Delaware Act and the General Partner hereby amends and
restates the Third Restated Agreement in its entirety. This amendment and
restatement shall become effective on the date of this Agreement. Except as
expressly provided to the contrary in this Agreement, the rights, duties,
liabilities and obligations of the Partners and the administration, dissolution
and termination of the Partnership shall be governed by the Delaware Act. All
Partnership Interests shall constitute personal property of the owner thereof
for all purposes.
Section 2.2    Name. The name of the Partnership shall be “MPLX LP”. Subject to
applicable law, the Partnership’s business may be conducted under any other name
or names as determined by the General Partner, including the name of the General
Partner. The words “Limited Partnership,” “L.P.,” “Ltd.” or similar words or
letters shall be included in the Partnership’s name where necessary for the
purpose of complying with the laws of any jurisdiction that so requires. The
General Partner may change the name of the Partnership at any time and from time
to time and shall notify the Limited Partners of such change in the next regular
communication to the Limited Partners.
Section 2.3    Registered Office; Registered Agent; Principal Office; Other

of Delaware at such registered office shall be The Corporation Trust Company.
The principal office of the Partnership shall be located at 200 East Hardin
Street, Findlay, Ohio 45840, or such other place as the General Partner may from
time to time designate by notice to the Limited Partners. The Partnership may
maintain offices at such other place or places within or outside the State of
Delaware as the General Partner determines to be necessary or appropriate. The
address of the General Partner shall be 200 East Hardin Street, Findlay, Ohio
45840, or such other place as the General Partner may from time to time
designate by notice to the Limited Partners.
Section 2.4    Purpose and Business. The purpose and nature of the business to
be conducted by the Partnership shall be to (a) engage directly in, or enter
into or form, hold and dispose of any corporation, partnership, joint venture,
limited liability company or other arrangement to engage indirectly in, any
business activity that is approved by the General Partner

26

--------------------------------------------------------------------------------

and that lawfully may be conducted by a limited partnership organized pursuant
to the Delaware Act and, in connection therewith, to exercise all of the rights
and powers conferred upon the Partnership pursuant to the agreements relating to
such business activity, and (b) do anything necessary or appropriate to the
foregoing, including the making of capital contributions or loans to a Group
Member; provided, however, that the General Partner shall not cause the
Partnership to engage, directly or indirectly, in any business activity that the
General Partner determines would be reasonably likely to cause the Partnership
to be treated as an association taxable as a corporation or otherwise taxable as
an entity for federal income tax purposes. To the fullest extent permitted by
law, the General Partner shall have no duty or obligation to propose or approve
the conduct by the Partnership of any business and may decline to do so free of
any fiduciary duty or obligation whatsoever to the Partnership or any Limited
Partner and, in declining to so propose or approve, shall not be required to act
in good faith or pursuant to any other standard imposed by this Agreement, any
Group Member Agreement, any other agreement contemplated hereby or under the
Delaware Act or any other law, rule or regulation or at equity and the General
Partner in determining whether to propose or approve the conduct by the
Partnership of any business shall be permitted to do so in its sole and absolute
discretion.
Section 2.5    Powers. The Partnership shall be empowered to do any and all acts
and things necessary, appropriate, proper, advisable, incidental to or
convenient for the furtherance and accomplishment of the purposes and business
described in Section 2.4 and for the protection and benefit of the Partnership.
Section 2.6    Term. The term of the Partnership commenced upon the filing of
the Certificate of Limited Partnership in accordance with the Delaware Act and

as a separate legal entity shall continue until the cancellation of the
Certificate of Limited Partnership as provided in the Delaware Act.
Section 2.7    Title to Partnership Assets. Title to Partnership assets, whether
real, personal or mixed and whether tangible or intangible, shall be deemed to
be owned by the Partnership as an entity, and no Partner, individually or
collectively, shall have any ownership interest in such Partnership assets or
any portion thereof. Title to any or all of the Partnership assets may be held
in the name of the Partnership, the General Partner, one or more of its
Affiliates or one or more nominees of the General Partner or its Affiliates, as
the General Partner may determine. The General Partner hereby declares and
warrants that any Partnership assets for which record title is held in the name
of the General Partner or one or more of its Affiliates or one or more nominees
of the General Partner or its Affiliates shall be held by the General Partner or
such Affiliate or nominee for the use and benefit of the Partnership in
accordance with the provisions of this Agreement; provided, however, that the
General Partner shall use reasonable efforts to cause record title to such
assets (other than those assets in respect of which the General Partner
determines that the expense and difficulty of conveyancing makes transfer of
record title to the Partnership impracticable) to be vested in the Partnership
or one or more of the Partnership’s designated Affiliates as soon as reasonably
practicable; provided further, that, prior to the withdrawal or removal of the
General Partner or as soon thereafter as practicable, the General Partner shall
use reasonable efforts to effect the transfer of record title to the Partnership
and, prior to any such transfer, will provide for the use of such assets in a
manner satisfactory to any successor General Partner. All Partnership assets
shall be recorded as the property of the

27

--------------------------------------------------------------------------------

Partnership in its books and records, irrespective of the name in which record
title to such Partnership assets is held.

ARTICLE III

such, shall participate in the operation, management or control (within the
meaning of the Delaware Act) of the Partnership’s business, transact any
business in the Partnership’s name or have the power to sign documents for or
otherwise bind the Partnership. No action taken by any Affiliate of the General
Partner or any officer, director, employee, manager, member, general partner,
agent or trustee of the General Partner or any of its Affiliates, or any
officer, director, employee, manager, member, general partner, agent or trustee
of a Group Member, in its capacity as such, shall be deemed to be participating
in the control of the business of the Partnership by a limited partner of the
Partnership (within the meaning of Section 17-303(a) of the Delaware Act) nor
shall any such action affect, impair or eliminate the limitations on the
liability of the Limited Partners under this Agreement.
Section 3.3    Rights of Limited Partners.

(a)Each Limited Partner shall have the right, for a purpose reasonably related
to such Limited Partner’s interest as a Limited Partner in the Partnership, upon
reasonable written demand stating the purpose of such demand, and at such
Limited Partner’s own expense:
(i)    to obtain from the General Partner either (A) the Partnership’s most
recent filings with the Commission on Form 10-K and any subsequent filings on
Form 10-Q and 8-K or (B) if the Partnership is no longer subject to the
reporting requirements of the Exchange Act, the information specified in, and
meeting the requirements of, Rule 144A(d)(4) under the Securities Act (provided
that the foregoing materials shall be deemed to be available to a Limited
Partner in satisfaction of the requirements of this Section 3.3(a)(i) if posted
on or accessible through the Partnership’s or the Commission’s website);
(ii)    to obtain a current list of the name and last known business, residence
or mailing address of each Partner; and
(iii)    to obtain a copy of this Agreement and the Certificate of Limited
Partnership and all amendments thereto.
(b)    To the fullest extent permitted by law, the rights to information granted
the Limited Partners pursuant to Section 3.3(a) replace in their entirety any
rights to information provided for in Section 17-305(a) of the Delaware Act and
each of the Partners and each other Person or Group who acquires an interest in
the Partnership hereby agrees to the fullest extent permitted by law that they
do not have any rights as Partners or interest holders to receive any
information either pursuant to Sections 17-305(a) of the Delaware Act or
otherwise except for the information identified in Section 3.3(a).

28

--------------------------------------------------------------------------------

(c)    The General Partner may keep confidential from the Limited Partners, for
such period of time as the General Partner deems reasonable, (i) any information
that the General Partner reasonably believes to be in the nature of trade
secrets or (ii) other information the disclosure of which the General Partner in
good faith believes (A) is not in the best interests of the Partnership Group,
(B) could damage the Partnership Group or its business or (C) that any Group
Member is required by law or by agreement with any third party to keep
confidential (other than agreements with Affiliates of the Partnership the
primary purpose of which is to circumvent the obligations set forth in this
Section 3.3).
(d)    Notwithstanding any other provision of this Agreement or Section 17-305
of the Delaware Act, each of the Record Holders, each other Person or Group who
acquires an interest in a Partnership Interest and each other Person bound by
this Agreement hereby agrees to the fullest extent permitted by law that they do
not have rights to receive information from the Partnership or any Indemnitee
for the purpose of determining whether to pursue litigation or assist in pending
litigation against the Partnership or any Indemnitee relating to the affairs of
the Partnership except pursuant to the applicable rules of discovery relating to
litigation commenced by such Person or Group.
ARTICLE IV
CERTIFICATES; RECORD HOLDERS; TRANSFER OF PARTNERSHIP INTERESTS; REDEMPTION OF
PARTNERSHIP INTERESTS
Section 4.1    Certificates. Record Holders of Partnership Interests and, where
appropriate, Derivative Partnership Interests, shall be recorded in the
Partnership Register and ownership of such interests shall be evidenced by a
physical certificate or book entry notation in the Partnership Register.
Notwithstanding anything to the contrary in this Agreement, unless the General
Partner shall determine otherwise in respect of some or all of any or all
classes of Partnership Interests, Partnership Interests shall not be evidenced
by physical certificates. Certificates, if any, shall be executed on behalf of
the Partnership by the Chief Executive Officer, President, Chief Financial
Officer or any Executive Vice President, Senior Vice President or Vice President
and the Secretary, any Assistant Secretary, or other authorized officer of the
General Partner, and shall bear the legend set forth in Section 4.8(f). The
signatures of such officers upon a certificate may, to the extent permitted by
law, be facsimiles. In case any officer who has signed or whose signature has
been placed upon such certificate shall have ceased to be such officer before
such certificate is issued, it may be issued by the Partnership with the same
effect as if he or she were such officer at the date of its issuance. If a
Transfer Agent has been appointed for a class of Partnership Interests, no
Certificate for such class of Partnership Interests shall be valid for any
purpose until it has been countersigned by the Transfer Agent; provided,
however, that, if the General Partner elects to cause the Partnership to issue
Partnership Interests of such class in global form, the Certificate shall be
valid upon receipt of a certificate from the Transfer Agent certifying that the
Partnership Interests have been duly registered in accordance with the
directions of the Partnership. With respect to any Partnership Interests that
are represented by physical certificates, the General Partner may determine that
such Partnership Interests will no longer be represented by physical
certificates and may, upon written notice to the holders of such Partnership
Interests and subject to applicable law, take whatever actions it deems
necessary or appropriate to cause such Partnership Interests to be registered in
book entry or global form and may cause such physical certificates to be
cancelled or deemed cancelled.

29

--------------------------------------------------------------------------------

Section 4.2        Mutilated, Destroyed, Lost or Stolen Certificates.
(a)    If any mutilated Certificate is surrendered to the Transfer Agent, the
appropriate officers of the General Partner on behalf of the Partnership shall
execute, and the Transfer Agent shall countersign and deliver in exchange
therefor, a new Certificate evidencing the same number and type of Partnership
Interests as the Certificate so surrendered.
(b)    The appropriate officers of the General Partner on behalf of the
Partnership shall execute and deliver, and the Transfer Agent shall countersign,
a new Certificate in place of any Certificate previously issued, if the Record
Holder of the Certificate:
(i)    makes proof by affidavit, in form and substance satisfactory to the
General Partner, that a previously issued Certificate has been lost, destroyed
or stolen;
(ii)    requests the issuance of a new Certificate before the General Partner
has notice that the Certificate has been acquired by a purchaser for value in
good faith and without notice of an adverse claim;
(iii)    if requested by the General Partner, delivers to the General Partner a
bond, in form and substance satisfactory to the General Partner, with surety or
sureties and with fixed or open penalty as the General Partner may direct to
indemnify the Partnership, the Partners, the General Partner and the Transfer
Agent against any claim that may be made on account of the alleged loss,
destruction or theft of the Certificate; and
(iv)    satisfies any other reasonable requirements imposed by the General
Partner or the Transfer Agent.
If a Limited Partner fails to notify the General Partner within a reasonable
period of time after such Limited Partner has notice of the loss, destruction or
theft of a Certificate, and a transfer of the Limited Partner Interests
represented by the Certificate is registered before the Partnership, the General
Partner or the Transfer Agent receives such notification, to the fullest extent
permitted by law, the Limited Partner shall be precluded from making any claim
against the Partnership, the General Partner or the Transfer Agent for such
transfer or for a new Certificate.
(c)    As a condition to the issuance of any new Certificate under this
Section 4.2, the General Partner may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Transfer
Agent) reasonably connected therewith.
Section 4.3    Record Holders. The names and addresses of Unitholders as they
appear in the Partnership Register shall be the official list of Record Holders
of the Partnership Interests for all purposes. The Partnership and the General
Partner shall be entitled to recognize the Record Holder as the Partner with
respect to any Partnership Interest and, accordingly, shall not be bound to
recognize any equitable or other claim to, or interest in, such Partnership
Interest on the part of any other Person or Group, regardless of whether the
Partnership or the General Partner shall have actual or other notice thereof,
except as otherwise provided by law or any applicable rule, regulation,
guideline or requirement of any National Securities Exchange on which such
Partnership Interests are listed or admitted to trading. Without limiting the
foregoing,

30

--------------------------------------------------------------------------------

when a Person (such as a broker, dealer, bank, trust company or clearing
corporation or an agent of any of the foregoing) is acting as nominee, agent or
in some other representative capacity for another Person or Group in acquiring
and/or holding Partnership Interests, as between the Partnership on the one
hand, and such other Person on the other, such representative Person shall be

obligations of a Partner hereunder as, and to the extent, provided herein,

another Person and includes a sale, assignment, gift, pledge, encumbrance,
hypothecation, mortgage, exchange or any other disposition by law or otherwise
or (ii) by which the holder of a Limited Partner Interest assigns all or a part
of such Limited Partner Interest to another Person who is or becomes a Limited
Partner as a result thereof, and includes a sale, assignment, gift, exchange or
any other disposition by law or otherwise, excluding a pledge, encumbrance,
hypothecation or mortgage but including any transfer upon foreclosure of any
pledge, encumbrance, hypothecation or mortgage.

(b)    No Partnership Interest shall be transferred, in whole or in part, except
in accordance with the terms and conditions set forth in this Article IV. Any
transfer or purported transfer of a Partnership Interest not made in accordance
with this Article IV shall be null and void, and the Partnership shall have no
obligation to effect any such transfer or purported transfer.
(c)    Nothing contained in this Agreement shall be construed to prevent or
limit a disposition by any stockholder, member, partner or other owner of the
General Partner or any Limited Partner of any or all of such Person’s shares of
stock, membership interests, partnership interests or other ownership interests
in the General Partner or such Limited Partner and the term “transfer” shall not
include any such disposition.
Section 4.5    Registration and Transfer of Limited Partner Interests.
(a)    The General Partner shall maintain, or cause to be maintained by the
Transfer Agent in whole or in part, the Partnership Register on behalf of the
Partnership.
(b)    The General Partner shall not recognize any transfer of Limited Partner
Interests evidenced by Certificates until the Certificates evidencing such
Limited Partner Interests are duly endorsed and surrendered for registration of
transfer. No charge shall be imposed by the General Partner for such transfer;
provided, however, that as a condition to the issuance of any new Certificate
under this Section 4.5, the General Partner may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed
with respect thereto. Upon surrender of a Certificate for registration of
transfer of any Limited Partner Interests evidenced by a Certificate, and
subject to the provisions of this Section 4.5(b), the appropriate officers of
the General Partner on behalf of the Partnership shall execute and

31

--------------------------------------------------------------------------------

deliver, and in the case of Certificates evidencing Limited Partner Interests
for which a Transfer Agent has been appointed, the Transfer Agent shall
countersign and deliver, in the name of the holder or the designated transferee
or transferees, as required pursuant to the holder’s instructions, one or more
new Certificates evidencing the same aggregate number and type of Limited
Partner Interests as was evidenced by the Certificate so surrendered. Upon the
proper surrender of a Certificate, such transfer shall be recorded in the
Partnership Register.
(c)    Upon the receipt of proper transfer instructions from the Record Holder
of uncertificated Partnership Interests, such transfer shall be recorded in the
Partnership Register.
(d)    Except as provided in Section 4.9, by acceptance of any Limited Partner
Interests pursuant to a transfer in accordance with this Article IV, each
transferee of a Limited Partner Interest (including any nominee, or agent or
representative acquiring such Limited Partner Interests for the account of
another Person or Group) (i) shall be admitted to the Partnership as a Limited
Partner with respect to the Limited Partner Interests so transferred to such
Person when any such transfer or admission is reflected in the Partnership
Register and such Person becomes the Record Holder of the Limited Partner
Interests so transferred, (ii) shall become bound, and shall be deemed to have
agreed to be bound, by the terms of this Agreement, (iii) represents that the
transferee has the capacity, power and authority to enter into this Agreement,
(iv) makes the consents, acknowledgements and waivers contained in this
Agreement, all with or without execution of this Agreement by such Person and
(v) shall be deemed to certify that the transferee is not an Ineligible Holder.
The transfer of any Limited Partner Interests and the admission of any new
Limited Partner shall not constitute an amendment to this Agreement.
(e)    Subject to (i) the foregoing provisions of this Section 4.5,
(ii) Section 4.3, (iii) Section 4.8, (iv) with respect to any class or series of
Limited Partner Interests, the provisions of any statement of designations or an
amendment to this Agreement establishing such class or series, (v) any
contractual provisions binding on any Limited Partner and (vi) provisions of
applicable law including the Securities Act, Limited Partner Interests shall be
freely transferable.
(f)    The General Partner and its Affiliates shall have the right at any time
to transfer their Common Units to one or more Persons.
Section 4.6    Transfer of the General Partner’s General Partner Interest.
(a)    Subject to Section 4.6(c) below, prior to December 31, 2022, the General
Partner shall not transfer all or any part of its General Partner Interest to a
Person unless such transfer (i) has been approved by the prior written consent
or vote of the holders of a majority of the Voting Eligible Common Units
(excluding Common Units owned by the General Partner and its Affiliates) and
Series A Preferred Units (as described in Section 5.14(b)(iii)(A)) voting
together as a single class, (ii) is of all, but not less than all, of its
General Partner Interest to (A) an Affiliate of the General Partner (other than
an individual) or (B) another Person (other than an individual) in connection
with the merger or consolidation of the General Partner with or into such other
Person or the transfer by the General Partner of all or substantially all of its
assets to

32

--------------------------------------------------------------------------------

such other Person or (iii) is pursuant to a bona fide foreclosure by the lenders
under any debt instrument with respect to which the General Partner is an
obligor or guarantor.
(b)    Subject to Section 4.6(c) below, on or after December 31, 2022, the
General Partner may transfer all or any part of its General Partner Interest
without the approval of any Limited Partner or any other Person.
(c)    Notwithstanding anything herein to the contrary, no transfer by the
General Partner of all or any part of its General Partner Interest to another
Person shall be permitted unless (i) the transferee agrees to assume the rights
and duties of the General Partner under this Agreement and to be bound by the
provisions of this Agreement, (ii) the Partnership receives an Opinion of
Counsel that such transfer would not result in the loss of limited liability of
any Limited Partner under the Delaware Act or cause the Partnership to be
treated as an association taxable as a corporation or otherwise to be taxed as
an entity for federal income tax purposes (to the extent not already so treated
or taxed) and (iii) such transferee also agrees to purchase all (or the
appropriate portion thereof, if applicable) of the partnership or membership
interest owned by the General Partner as the general partner or managing member,
if any, of each other Group Member. In the case of a transfer pursuant to and in
compliance with this Section 4.6, the transferee or successor (as the case may
be) shall, subject to compliance with the terms of Section 10.2, be admitted to
the Partnership as the General Partner effective immediately prior to the
transfer of the General Partner Interest, and the business of the Partnership
shall continue without dissolution.
Section 4.7    [Reserved.]
Section 4.8    Restrictions on Transfers.
(a)    Except as provided in Section 4.8(e), notwithstanding the other
provisions of this Article IV, no transfer of any Partnership Interests shall be
made if such transfer would (i) violate the then applicable federal or state
securities laws or rules and regulations of the Commission, any state securities
commission or any other governmental authority with jurisdiction over such
transfer, (ii) terminate the existence or qualification of the Partnership under
the laws of the jurisdiction of its formation, or (iii) cause the Partnership to
be treated as an association taxable as a corporation or otherwise to be taxed
as an entity for federal income tax purposes (to the extent not already so
treated or taxed). The Partnership may issue stop transfer instructions to any
Transfer Agent in order to implement any restriction on transfer contemplated by
this Agreement.
(b)    The General Partner may impose restrictions on the transfer of
Partnership Interests if it receives an Opinion of Counsel that such
restrictions are necessary to (i) avoid a significant risk of the Partnership’s
becoming taxable as a corporation or otherwise becoming taxable as an entity for
federal income tax purposes (to the extent not already so treated or taxed) or
(ii) preserve the uniformity of the Limited Partner Interests (or any class or
classes thereof). The General Partner may impose such restrictions by amending
this Agreement; provided, however, that any amendment that would result in the
delisting or suspension of trading of any class of Limited Partner Interests on
the principal National Securities Exchange on which such class of Limited
Partner Interests is then listed or admitted to trading must be approved, prior

(i)    The transfer of Series A Preferred Units shall be subject to the
restrictions imposed by Section 5.14(b)(viii).
Section 4.9    Eligibility Certificates; Ineligible Holders.
(a)        The General Partner may upon demand or on a regular basis require
Limited Partners, and transferees of Limited Partner Interests in connection
with a transfer, to execute an Eligibility Certificate or provide other
information as is necessary for the General Partner to determine if any such
Limited Partners or transferees are Ineligible Holders.
(b)    If any Limited Partner (or its beneficial owners) fails to furnish to the
General Partner within 30 days of its request an Eligibility Certificate and
other information related thereto, or if upon receipt of such Eligibility
Certificate or other requested information the General Partner determines that a
Limited Partner or a transferee of a Limited Partner is 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 or the General
Partner may refuse to effect the transfer of the Limited Partner Interests to
such transferee. In addition, the General Partner shall be substituted for any
Limited Partner that is an Ineligible Holder as the Limited Partner in respect
of the Ineligible Holder’s Limited Partner Interests.
(c)    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 Partner Interests
other than those of Ineligible Holders are cast, either for, against or
abstaining as to the matter.
(d)    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 its Limited Partner Interest (representing the right to receive its share of
such distribution in kind).
(e)    At any time after an Ineligible Holder can and does certify that it no
longer is an Ineligible Holder, it 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 upon
approval of the General Partner, shall no longer constitute an Ineligible Holder
and the General Partner shall cease to be deemed to be the Limited Partner in
respect of such Limited Partner Interests.
(f)    If at any time a transferee of a Partnership Interest fails to furnish an
Eligibility Certificate or any other information requested by the General
Partner pursuant to Section 4.9 within 30 days of such request, or if upon
receipt of such Eligibility Certificate or other information the General Partner
determines, with the advice of counsel, that such transferee is an Ineligible
Holder, the Partnership may, unless the transferee establishes to the
satisfaction

35

--------------------------------------------------------------------------------

of the General Partner that such transferee is not an Ineligible Holder,
prohibit and void the transfer, including by placing a stop order with the
Transfer Agent.
Section 4.10    Redemption of Partnership Interests of Ineligible Holders.
(a)        If at any time a Limited Partner fails to furnish an Eligibility
Certificate or any other information requested within the period of time
specified in Section 4.9, or if upon receipt of such Eligibility Certificate 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 not an Ineligible Holder and who furnishes
an Eligibility Certificate 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 such
Limited Partner’s 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 such 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 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 such Limited Partner’s 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.

36

--------------------------------------------------------------------------------

(b)    The provisions of this Section 4.10 shall also be applicable to Limited
Partner Interests held by a Limited Partner as nominee, agent or representative
of a Person determined to be an Ineligible 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 and the
transferor provides notice of such transfer to the General Partner. 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 such transferee is not an
Ineligible Holder. If the transferee fails to make such certification within 30
days after the request and, in any event, before the redemption date, such
redemption shall be effected from the transferee on the original redemption
date.
ARTICLE V
CAPITAL CONTRIBUTIONS AND ISSUANCE OF PARTNERSHIP INTERESTS
Section 5.1    Conversion of the General Partner Interest and Cancellation of
Incentive Distribution Rights.
(a)        Pursuant to this Agreement and the Partnership Restructuring
Agreement, the economic general partner interest in the Partnership that existed
immediately prior to the execution of this Agreement and evidenced by General
Partner Units is hereby converted into a non-economic General Partner Interest
in the Partnership and all of the General Partner Units are hereby redeemed by
the Partnership and cancelled. As of the execution of this Agreement, the
General Partner hereby continues as the general partner of the Partnership and
holds the General Partner Interest and the Partnership is hereby continued
without dissolution.
(b)    Concurrently with the execution of this Agreement and pursuant to this
Agreement and the Partnership Restructuring Agreement, all Incentive
Distribution Rights in the Partnership that were outstanding and held by the
General Partner immediately prior to the execution of this Agreement are hereby
redeemed by the Partnership and cancelled.
(c)    Concurrently with the execution of this Agreement and pursuant to the
Partnership Restructuring Agreement, in consideration for the transactions set
forth in Section 5.1(a) and Section 5.1(b), the Partnership is issuing
275,000,000 Common Units to the General Partner on the date hereof, which
issuance is hereby authorized and approved.
Section 5.2    Contributions by the General Partner. Except as provided for in
Section 12.8, the General Partner is not obligated to make any additional
Capital Contributions to the Partnership.
Section 5.3    Contributions by Limited Partner. 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

37

--------------------------------------------------------------------------------

upon termination 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, agent or representative in any case in
which such nominee, agent or representative has furnished the 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) 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 in respect of each such Partnership Interest be increased by (i)
the amount of all Capital Contributions made to the Partnership with respect to
such Partnership Interest and (ii) all items of Partnership income and gain
(including 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 actual and deemed distributions of cash or property made with respect to
such Partnership Interest 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. For the avoidance of doubt, the
Series A Preferred Units will be treated as a partnership interest in the
Partnership that is “convertible equity” within the meaning of Treasury
Regulation Section 1.721-2(g)(3), and, therefore, each holder of a Series A
Preferred Unit will be treated as a partner in the Partnership. The initial
Capital Account balance in respect of each Series A Preferred Unit shall be the
Series A Issue Price, as such amount may be adjusted in accordance with the
Series A Purchase Agreement for any reduction attributable to the Transaction
Fee, as such term is defined in the Series A Purchase Agreement and expenses
reimbursable under the Series A Purchase Agreement.

(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 or governing,
organizational or similar documents) of all property owned by (A) any other
Group Member that is classified as a partnership or disregarded entity for
federal income tax purposes and (B) any other partnership, limited liability
company, unincorporated business or other entity classified as a partnership or
disregarded entity for federal income tax purposes of which a Group Member is,
directly or indirectly, a partner, member or other equity holder.

38

--------------------------------------------------------------------------------

(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 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 this Agreement or 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. 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)    In the event the Carrying Value of Partnership property is adjusted
pursuant to Section 5.5(d), any Unrealized Gain resulting from such adjustment
shall be treated as an item of gain and any Unrealized Loss resulting from such
adjustment shall be treated as an item of loss.
(v)    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.
(vi)    An item of income of the Partnership that is described in
Section 705(a)(1)(B) of the Code (with respect to items of income that are
exempt from tax) shall be treated as an item of income for the purpose of this
Section 5.5(b), and an item of expense of the Partnership that is described in
Section 705(a)(2)(B) of the Code (with respect to expenditures that are not
deductible and not chargeable to capital accounts), shall be treated as an item
of deduction for the purpose of this Section 5.5(b).
(vii)    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.
(viii)    To the extent required by Treasury Regulation Section 1.752-7, 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

39

--------------------------------------------------------------------------------

Partnership) or an item of gain (if the adjustment decreases the Carrying Value
of such Liability of the Partnership).
(c)    (i) Except as otherwise provided in this Section 5.5(c), 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)    [Reserved.]
(iii)    [Reserved.]
(iv)    [Reserved.]
(d)    (i) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f),
on an issuance of additional Partnership Interests for cash or Contributed
Property, the issuance of Partnership Interests as consideration for the
provision of services, the Carrying Value of each Partnership property
immediately prior to such issuance shall be adjusted upward or downward to
reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership
property; provided, however, that in the event of an issuance of Partnership
Interests for a de minimis amount of cash or Contributed Property, or in the
event of an issuance of a de minimis amount of Partnership 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. 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 the issuance of additional Partnership
Interests shall be determined by the General Partner using such method of
valuation as it may adopt. In making its determination of the fair market values
of individual properties, the General Partner may determine that it is
appropriate to first determine an aggregate value for the Partnership, derived
from the current trading price of the Common Units, and taking fully into
account the fair market value of the Partnership Interests of all Partners at
such time and make any adjustments necessary to reflect the difference, if any,
between the fair market value of any Series A Preferred Units for which the
Series A Conversion Date has not occurred and the aggregate Capital Accounts
attributable to such Series A 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), and then allocate such aggregate value among
the individual properties of the Partnership (in such manner as it determines
appropriate).
(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 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. 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

40

--------------------------------------------------------------------------------

provided in Section 5.5(d)(i) or (B) 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.
(iii)    In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(s),
immediately after the conversion of a Series A Preferred Unit into Common Units
in accordance with Section 5.14(b)(vi), the Capital Account of each Partner and
the Carrying Value of each Partnership property shall be adjusted 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
after such conversion and (A) first, all Unrealized Gain (if the Capital Account
of each such Series A Conversion Unit is less than the Per Unit Capital Account
for a then outstanding Initial Common Unit) or Unrealized Loss (if the Capital
Account of each such Series A Conversion Unit is greater than the Per Unit
Capital Account for a then outstanding Initial Common Unit) had been allocated
to each Partner holding Series A Conversion Units received upon such conversion,
Pro Rata, until the Capital Account of each such Series A Conversion Unit is
equal to the Per Unit Capital Amount for a then outstanding Initial Common Unit;
and (B) second, any remaining Unrealized Gain or Unrealized Loss had been
allocated to the Partners at such time pursuant to Section 6.1(d).  In
determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount
and fair market value of all Partnership assets (including, without limitation,
cash or cash equivalents) immediately after the conversion of a Series A
Preferred Unit shall be determined by the General Partner using such reasonable
method of valuation as it may adopt; provided, however, that the General
Partner, in arriving at such valuation, must take fully into account the fair
market value of the Partnership Interests of all Partners at such time and must
make such adjustments to such valuation as required by 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 in its discretion to be reasonable.  If, after making the allocations
of Unrealized Gain and Unrealized Loss as set forth above in
this Section 5.5(d)(iii), the Capital Account of each Partner with respect to
each Series A Conversion Unit received upon such conversion of the Series A
Preferred Unit is different from the Per Unit Capital Amount for a then
outstanding Initial Common Unit, then Capital Account balances shall be
reallocated between the Partners holding Common Units (other than Series A
Conversion Units) and Partners holding Series A Conversion Units so as to cause
the Capital Account of each Partner holding a Series A Conversion Unit to equal,
on a per Limited Partner Unit basis with respect to each such Series A
Conversion Unit, the Per Unit Capital Amount for a then outstanding Initial
Common Unit.
Section 5.6    Issuances of Additional Partnership Interests.
(a)        Subject to Section 5.14(b)(iv), the Partnership may issue additional
Partnership Interests (other than General Partner Interests) and Derivative
Partnership Interests 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

41

--------------------------------------------------------------------------------

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; (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 Derivative Partnership Interests pursuant to this Section 5.6,
(ii) the conversion of the Combined Interest into Limited Partner Units pursuant
to the terms of this Agreement, (iii) reflecting admission of such additional
Limited Partners in the Partnership Register as the Record Holders of such
Limited Partner Interests and (iv) all additional issuances of Partnership
Interests and Derivative Partnership Interests. The General Partner shall
determine the relative rights, powers and duties of the holders of the Limited
Partner Units or other Partnership Interests or Derivative 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 Derivative Partnership Interests or in connection
with the conversion of the Combined Interest into Limited Partner Units pursuant
to the terms of this Agreement, including compliance with any statute, rule,
regulation or guideline of any federal, state or other governmental agency or
any National Securities Exchange on which the Limited Partner Units or other
Partnership Interests are listed or admitted to trading.
(d)    No fractional Limited Partner 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
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, held in the treasury
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, 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, to the extent necessary to maintain the
Percentage Interests of the General Partner and its Affiliates equal to that
which existed immediately prior to the issuance of such Partnership Interests.

42

--------------------------------------------------------------------------------

Section 5.9    Splits and Combinations.

(a)Subject to Section 5.9(e) and Section 5.14(b)(vi)(E), the Partnership may
make a Pro Rata distribution of Partnership Interests 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
Limited Partner Unit basis or stated as a number of Limited Partner Units
(including the number of Common Units into which Series A Preferred Units may
convert) are proportionately adjusted.

(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 (or
such shorter periods as required by applicable law). 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)    [Reserved.]
(d)    Promptly following any such distribution, subdivision or combination, the
Partnership may issue Certificates or uncertificated Partnership Interests 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 the delivery to a
Record Holder of Partnership Interests represented by Certificates, the
surrender of any Certificate held by such Record Holder immediately prior to
such Record Date.
(e)    The Partnership shall not issue fractional Limited Partner Units upon any
distribution, subdivision or combination of Limited Partner Units. If a
distribution, subdivision or combination of Limited Partner Units would result
in the issuance of fractional Limited Partner Units but for the provisions of
Section 5.6(d) and this Section 5.9(e), each fractional Limited Partner Unit
shall be rounded to the nearest whole Limited Partner Unit (with fractional
Limited Partner Units equal to or greater than a 0.5 Limited Partner Unit being
rounded to the next higher Limited Partner 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 Sections 17-303, 17-607 or 17-804 of the Delaware Act.

Section 5.11    [Reserved.]
Section 5.12    [Reserved.]
Section 5.13    [Reserved.]
Section 5.14    Establishment of Series A Preferred Units.
(a)General. Pursuant to the Second Amended and Restated Partnership Agreement,
there was created a class of Limited Partner Units designated as “Series A
Convertible Preferred Units” (the “Series A Preferred Units”), with the
designations, preferences and relative, participating, optional or other special
rights, powers and duties as set forth in this Section 5.14 and elsewhere in
this Agreement.
(b)    Rights of Series A Preferred Units. The Series A Preferred Units shall
have the following rights, preferences and privileges and the Series A Preferred
Unitholders shall be subject to the following duties and obligations:
(i)    Distributions.
(A)    Subject to Section 5.14(b)(i)(B), commencing with the Quarter ending on
June 30, 2016, subject to Section 5.14(b)(i)(D), the Record Holders of the
Series A Preferred Units as of the applicable Record Date for each Quarter shall
be entitled to receive, in respect of each outstanding Series A Preferred Unit,
cumulative distributions in respect of such Quarter equal to the sum of (1) the
Series A Distribution Amount for such Quarter and (2) any Series A Unpaid Cash
Distributions (collectively, a “Series A Quarterly Distribution”). Each Series A
Quarterly Distribution shall be payable quarterly in cash within sixty (60) days
after the end of the applicable Quarter (each such payment date, a “Series A
Distribution Payment Date”). If the General Partner establishes an earlier
Record Date for any distribution to be made by the Partnership on other
Partnership Interests in respect of any Quarter, then the Record Date
established pursuant to this Section 5.14(b)(i) for a Series A Quarterly
Distribution in respect of such Quarter shall be the same Record Date. For the
avoidance of doubt, subject to Section 5.14(b)(i)(D), the Series A Preferred
Units shall not be entitled to any distributions made pursuant to Section 6.3(a)
for any Quarter so long as the Series A Quarterly Distribution has been declared
and paid in accordance with this Section 5.14(b)(i) on the Series A Preferred
Units with respect to such Quarter.
(B)    If the Partnership fails to pay in full the Series A Distribution Amount
of any Series A Quarterly Distribution in cash when due for any Quarter, then
from and after the first date of such failure and continuing until such failure
is cured by payment in full in cash of all such arrearages, (1) the amount of
such unpaid cash distributions (on a per Series A Preferred Unit basis, “Series
A Unpaid Cash Distributions”) unless and until paid will accrue and accumulate
from and including the first day of the Quarter immediately following the
Quarter in respect of which such payment is due until paid in full and (2) the
Partnership shall not be permitted to, and shall not, declare or make, any
distributions, redemptions or repurchases in respect of any Series A Junior
Securities or Series A Parity Securities (including, for the avoidance of doubt,
with respect to the Quarter for which the Partnership first failed to pay in
full the Series A Distribution Amount of any Series A Quarterly

44

--------------------------------------------------------------------------------

Distribution in cash when due); provided, however, that distributions may be
declared and paid on the Series A Preferred Units and the Series A Parity
Securities so long as such distributions are declared and paid pro rata so that
amounts of distributions declared per Series A Preferred Unit and Series A
Parity Security shall in all cases bear to each other the same ratio that
accrued and accumulated distributions per Series A Preferred Unit and Series A
Parity Security bear to each other.
(C)    The aggregate Series A Distribution Amount shall be paid out of Available
Cash that is deemed to be Operating Surplus for the applicable Quarter. To the
extent that any portion of a Series A Quarterly Distribution with respect to any
Quarter exceeds the amount of Available Cash that is deemed to be Operating
Surplus for such Quarter, the amount of cash equal to the Available Cash that is
deemed to be Operating Surplus for such Quarter will be paid to the Series A
Preferred Unitholders Pro Rata and the balance of such Series A Quarterly
Distribution shall be unpaid and shall constitute an arrearage and shall accrue
and accumulate as set forth in Section 5.14(b)(i)(B).
(D)    Notwithstanding anything in this Section 5.14(b)(i) to the contrary, with
respect to any Series A Preferred Unit that is converted into a Common Unit, the
Record Holder thereof shall not be entitled to a distribution in respect of such
Series A Preferred Unit and a distribution in respect of such Common Unit with
respect to the same period, but shall be entitled only to the distribution to be
paid based upon the class of Limited Partner Units held as of the close of
business on the applicable Record Date. For the avoidance of doubt, if a Series
A Conversion Date occurs prior to the close of business on a Record Date for
payment of a distribution on the Common Units, the applicable Record Holder of
Series A Preferred Units shall receive, with respect to any Series A Preferred
Units that have converted into Common Units, only the distribution in respect of
such Common Units with respect to such period.
(E)    [Reserved.]
(ii)    Issuance of the Series A Preferred Units. Subject to
Section 5.14(b)(iv), the Series A Preferred Units shall be issued by the
Partnership pursuant to the terms and conditions of the Series A Purchase
Agreement.
(iii)    Voting Rights.
(A)    Except as provided in Section 5.14(b)(iii)(B), the Voting Eligible Series
A Preferred Units shall have voting rights that are identical to the voting
rights of the Common Units and shall vote with the Common Units as a single
class, so that each Voting Eligible Series A Preferred Unit will be entitled to
one vote for each Common Unit into which such Series A Preferred Unit would be
convertible at the then applicable Series A Conversion Rate (regardless of
whether the Series A Preferred Units are then convertible) on each matter with
respect to which each Record Holder of a Common Unit is entitled to vote. Each
reference in this Agreement to a vote of Record Holders of Common Units shall be
deemed to be a reference to the Record Holders of Common Units and Series A
Preferred Units, voting together as a single class during any period in which
any Series A Preferred Units are outstanding.

45

--------------------------------------------------------------------------------

(B)    Notwithstanding any other provision of this Agreement, in addition to all
other requirements imposed by Delaware law, and all other voting rights granted
under this Agreement, the affirmative vote of the Record Holders of the Series A
Required Voting Percentage shall be required for any amendment to this Agreement
or the Certificate of Limited Partnership (including by merger or otherwise or
any amendment contemplated by and made in accordance with Section 5.14(b)(iv))
that is materially adverse to any of the rights, preferences and privileges of
the Series A Preferred Units. Without limiting the generality of the preceding
sentence, any amendment shall be deemed to have such a material adverse impact
if such amendment would:
(1)    Reduce the Series A Distribution Amount, change the form of payment of
distributions on the Series A Preferred Units, defer the date from which
distributions on the Series A Preferred Units will accrue, cancel accrued and
unpaid distributions on the Series A Preferred Units, or change the seniority
rights of the Series A Preferred Unitholders as to the payment of distributions
in relation to the holders of any other class or series of Partnership
Interests;
(2)    Reduce the amount payable or change the form of payment to the Record
Holders of the Series A Preferred Units upon the voluntary or involuntary
liquidation, dissolution or winding up, or sale of all or substantially all of
the assets, of the Partnership, or change the seniority of the liquidation
preferences of the Record Holders of the Series A Preferred Units in relation to
the rights upon liquidation of the holders of any other class or series of
Partnership Interests; or
(3)    Make the Series A Preferred Units redeemable or convertible at the option
of the Partnership other than as set forth herein.
(C)    Notwithstanding anything to the contrary in this Section 5.14(b)(iii), in
no event shall the consent of the Series A Preferred Unitholders, as a separate
class, be required in connection with any Series A Change of Control or
Partnership Restructuring Event. For the avoidance of doubt, the foregoing shall
not limit the voting rights of any Series A Preferred Unitholder in connection
with the vote of Record Holders of Common Units and Series A Preferred Units
together as a single class.
(D)    Notwithstanding any other provision of this Agreement, in addition to all
other voting rights granted under this Agreement, the Partnership shall not
declare or pay any distribution from Capital Surplus without the affirmative
vote of the Record Holders of the Series A Required Voting Percentage.
(iv)    No Series A Senior Securities; Series A Parity Securities. Other than
issuances contemplated by the Series A Purchase Agreement, the Partnership shall
not, without the affirmative vote of the Record Holders of the Series A Required
Voting Percentage, issue any (A) Series A Senior Securities (or amend the
provisions of any class of Partnership Interests to make such class of
Partnership Interests a class of Series A Senior Securities) or (B) Series A
Parity Securities (or amend the provisions of any class of Partnership Interests
to make such class of Partnership Interests a class of Series A Parity
Securities) or Series A Preferred Units; provided that, without the consent of
the holders of Voting Eligible

46

--------------------------------------------------------------------------------

Series A Preferred Units (but without prejudice to their rights under
Section 5.14(b)(iii)(A)), the Partnership may issue (1) at any time in the
aggregate, up to the greater of (a) an aggregate $500,000,000 of Series A Parity
Securities and (b) a number of Series A Parity Securities such that, as of the
date of the issuance of the Series A Parity Securities, the aggregate number of
Series A Parity Securities, together with the Series A Preferred Units, in each
case on an “as if” converted basis (or, if the Series A Parity Securities are
not convertible, assuming that such Series A Parity Securities are convertible
into a number of Common Units equal to the quotient of (i) the aggregate
purchase price for such Series A Parity Securities, divided by (ii) the
volume-weighted average price of the Common Units for the twenty (20) Trading
Day period ending immediately prior to such issuance (such Common Units, the
“Series A Parity Equivalent Units”)), equals no more than 15% of all outstanding
Common Units (including as outstanding for such purposes, (i) any Common Units
issuable in respect of the Series A Preferred Units at the then applicable
Series A Conversion Rate (regardless of whether the Series A Preferred Units are
then convertible), (ii) any Common Units issuable in respect of Series A Parity
Securities (including any warrants issued in connection with Series A Parity
Securities) at the initial or then applicable conversion rate, as applicable,
and (iii) any Series A Parity Equivalent Units), and (2) if a number of Series A
Preferred Units having an aggregate Series A Issue Price of less than
$500,000,000 is then outstanding, such number of Series A Parity Securities as
determined by the General Partner. Subject to Section 5.14(b)(vi)(E), the
Partnership may, without any vote of the holders of Voting Eligible Series A
Preferred Units (but without prejudice to their rights under
Section 5.14(b)(iii)(A)), create (by reclassification or otherwise) and issue
Series A Junior Securities in an unlimited amount.
(v)    Legends. Each book entry evidencing a Series A Preferred Unit shall bear
a restrictive notation in substantially the form set forth in Exhibit B.
(vi)    Conversion.
(A)    At the Option of the Series A Preferred Unitholders. Beginning with the
earlier of (i) the third anniversary of the Series A Issuance Date, and (ii)
immediately prior to the liquidation, dissolution and winding up of the
Partnership under Section 12.4, the Series A Preferred Units owned by any Series
A Preferred Unitholder shall be convertible, in whole or in part, at any time
and from time to time upon the request of such Series A Preferred Unitholder,
but not more than once per Quarter by such Series A Preferred Unitholder
(inclusive of any conversion by such Series A Preferred Unitholder’s Affiliates,
with each Series A Preferred Unitholder and its Affiliates being entitled to a
single conversion right per Quarter), into a number of Common Units determined
by multiplying the number of Series A Preferred Units to be converted by the
Series A Conversion Rate at such time; provided, however, that the Partnership
shall not be obligated to honor any such conversion request if such conversion
request does not involve an underlying value of Common Units of at least
$100,000,000 (taking into account any concurrent conversion requests by any
Affiliates of such Series A Preferred Unitholder) based on the Closing Price of
Common Units on the Trading Day immediately preceding the Series A Conversion
Notice Date (or a lesser amount to the extent such exercise covers all of such
Series A Preferred Unitholder’s Series A Preferred Units). Immediately upon the
issuance of Common Units as a result of any conversion of Series A Preferred
Units, all rights of the Series A Converting Unitholder with respect to such
Series A Preferred Units shall cease, including any further accrual of
distributions, and such Series A

47

--------------------------------------------------------------------------------

Converting Unitholder thereafter shall be treated for all purposes as the owner
of Common Units. Fractional Common Units shall not be issued to any Person
pursuant to this Section 5.14(b)(vi)(A) (each fractional Common Unit shall be
rounded down with the remainder being paid an amount in cash based on the
Closing Price of Common Units on the Trading Day immediately preceding the
Series A Conversion Notice Date).
(B)    At the Option of the Partnership. At any time following the fourth
anniversary of the Series A Issuance Date, the Partnership shall have the option
at any time, but not more than once per Quarter, to convert all or any portion
of the Series A Preferred Units then outstanding into a number of Common Units
determined by multiplying the number of Series A Preferred Units to be converted
by the Series A Conversion Rate. Fractional Common Units shall not be issued to
any Person pursuant to this Section 5.14(b)(vi)(B) (each fractional Common Unit
shall be rounded down with the remainder being paid an amount in cash based on
the Closing Price of Common Units on the Trading Day immediately preceding the
Series A Forced Conversion Notice Date). Notwithstanding the foregoing, in order
for the Partnership to exercise such option:
(1)    The Closing Price of the Common Units must be equal to or greater than
one hundred fifty percent (150%) of the Series A Issue Price for the twenty (20)
Trading Day period immediately preceding the Series A Forced Conversion Notice
Date;
(2)    The average daily trading volume of the Common Units on the National
Securities Exchange on which the Common Units are then listed or admitted to
trading must be equal to or exceed 1,000,000 (as such amount may be adjusted to
reflect any Limited Partner Unit split, combination or similar event) for the
twenty (20) Trading Day period immediately preceding the Series A Forced
Conversion Notice Date; and
(3)    The Partnership must have an effective registration statement on file
with the Commission covering resales of the underlying Common Units to be
received upon any such conversion, and
provided, that each such conversion by the Partnership shall be for an aggregate
amount of Series A Preferred Units involving an underlying value of Common Units
of at least $100,000,000 based on the Closing Price of Common Units on the
Trading Day immediately preceding the Series A Forced Conversion Notice Date (or
a lesser amount if such amount includes all then outstanding Series A Preferred
Units) and shall be allocated among the Series A Preferred Unitholders on a Pro
Rata basis or on such other basis as may be agreed upon by all Series A
Preferred Unitholders.
(C)    Conversion Notice.
(1)    To convert Series A Preferred Units into Common Units pursuant to
Section 5.14(b)(vi)(A), a Series A Converting Unitholder shall give written
notice (a “Series A Conversion Notice,” and the date such notice is received, a
“Series A Conversion Notice Date”) to the Partnership stating that such Series A
Preferred Unitholder

48

--------------------------------------------------------------------------------

elects to so convert Series A Preferred Units pursuant to Section 5.14(b)(vi)(A)
and the number of Series A Preferred Units to be converted.
(2)    To convert Series A Preferred Units into Common Units pursuant to
Section 5.14(b)(vi)(B), the Partnership shall give written notice (a “Series A
Forced Conversion Notice,” and the date such notice is received, a “Series A
Forced Conversion Notice Date”) to each Record Holder of Series A Preferred
Units stating that the Partnership elects to force conversion of Series A
Preferred Units pursuant to Section 5.14(b)(vi)(B) and the number of Series A
Preferred Units to be so converted. The Series A Conversion Units shall be
issued in the name of the Record Holder of such Series A Preferred Units.
(D)    Timing. If a Series A Conversion Notice is delivered by a Series A
Preferred Unitholder to the Partnership or a Series A Forced Conversion Notice
is delivered by the Partnership to a Series A Preferred Unitholder, each in
accordance with Section 5.14(b)(vi)(C), the Partnership shall issue the
applicable Series A Conversion Units no later than three (3) Business Days after
the Series A Conversion Notice Date or the Series A Forced Conversion Notice
Date, as the case may be, occurs (any date of issuance of such Common Units, and
any date of issuance of Common Units upon conversion of Series A Preferred Units
pursuant to Section 5.14(b)(vi)(G) or Section 5.14(b)(vii), a “Series A
Conversion Date”). On the Series A Conversion Date, the Partnership shall
instruct, and shall use its commercially reasonable efforts to cause, its
Transfer Agent to electronically transmit the Series A Conversion Units issuable
upon conversion to such Series A Preferred Unitholder (or designated
recipient(s)), by crediting the account of the Series A Preferred Unitholder (or
designated recipient(s)) prime broker with the Depository through its Deposit
Withdrawal Agent Commission system. The parties agree to coordinate with the
Depository to accomplish this objective. Upon issuance of Series A Conversion
Units to the Series A Converting Unitholder, all rights under the converted
Series A Preferred Units shall cease, and such Series A Converting Unitholder
shall be treated for all purposes as the Record Holder of such Series A
Conversion Units.
(E)    Distributions, Combinations, Subdivisions and Reclassifications by the
Partnership. If, after the Series A Issuance Date, the Partnership (i) makes a
distribution on its Common Units payable in Common Units or another Partnership
Interest, (ii) subdivides or splits its outstanding Common Units into a greater
number of Common Units, (iii) combines or reclassifies its Common Units into a
lesser number of Common Units, (iv) 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), (v) effects a Pro Rata repurchase of Common Units, in
each case other than in connection with a Series A Change of Control (which
shall be governed by Section 5.14(b)(vii)), (vi) issues to holders of Common
Units, in their capacity as holders of Common Units, rights, options or warrants
entitling them to subscribe for or purchase Common Units at less than the market
value thereof, (vii) distributes to holders of Common Units evidences of
indebtedness, Partnership Interests (other than Common Units) or other assets
(including securities, but excluding any distribution referred to in clause (i),
any rights or warrants referred to in clause (ii), any consideration payable in
connection with a tender or exchange offer made by the Partnership or any of its
subsidiaries and any distribution of Limited

49

--------------------------------------------------------------------------------

Partner Units or any class or series, or similar Partnership Interest, of or
relating to a subsidiary or other business unit in the case of certain spin-off
transactions described below), or (viii) consummates a spin-off, where the
Partnership makes a distribution to all holders of Common Units consisting of
Limited Partner Units of any class or series, or similar equity interests of, or
relating to, a subsidiary or other business unit, then the Series A Conversion
Rate, the Series A Conversion Floor Trigger and, solely for purposes of
Section 5.14(b)(vi)(B)(1), the Series A Issue Price, in each case, in effect at
the time of the Record Date for such distribution or the effective date of any
such other transaction shall be proportionately adjusted: (1) in respect of
clauses (i) through (iv) above, so that the conversion of the Series A Preferred
Units after such time shall entitle each Series A Preferred Unitholder to
receive the aggregate number of Common Units (or any Partnership Interests into
which such Common Units would have been combined, consolidated, merged or
reclassified, as applicable) that such Series A Preferred Unitholder would have
been entitled to receive if the Series A Preferred Units had been converted into
Common Units immediately prior to such Record Date or effective date, as the
case may be, (2) in respect of clauses (v) through (viii) above, in the
reasonable discretion of the General Partner to appropriately ensure that the
Series A Preferred Units are convertible into an economically equivalent number
of Common Units after taking into account the event described in clauses (vi)
through (viii) above, and (3) in addition to the foregoing, 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 in this Section 5.14 relating to the Series A Preferred
Units shall not be abridged or amended and that the Series A Preferred Units
shall thereafter retain the same powers, economic rights, preferences and
relative participating, optional and other special rights, and the
qualifications, limitations and restrictions thereon, that the Series A
Preferred Units had immediately prior to such transaction or event, and, solely
for purposes of Section 5.14(b)(vi)(B)(1), the Series A Issue Price, and any
other terms of the Series A Preferred Units that the General Partner in its
reasonable discretion determines require adjustment to achieve the economic
equivalence described below, shall be proportionately adjusted to take into
account any such subdivision, split, combination or reclassification. An
adjustment made pursuant to this Section 5.14(b)(vi)(E) 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 Partnership is the
surviving Person) or split. Such adjustment shall be made successively whenever
any event described above shall occur.
(F)    No Adjustments for Certain Items. Notwithstanding any of the other
provisions of this Section 5.14(b)(vi), no adjustment shall be made to the
Series A Conversion Rate, the Series A Conversion Floor Trigger or the Series A
Issue Price pursuant to Section 5.14(b)(vi)(E) as a result of any of the
following:
(1)    Any issuance of Partnership Interests in exchange for cash;
(2)    Any grant of Common Units or options, warrants or rights to purchase or
receive Common Units or the issuance of Common Units upon the exercise or
vesting of any such options, warrants or rights in respect of services provided
to or for the

50

--------------------------------------------------------------------------------

benefit of the Partnership or its Subsidiaries, under compensation plans and
agreements approved by the General Partner (including any long-term incentive
plan);
(3)    Any issuance of Common Units as all or part of the consideration to
effect (i) the closing of any acquisition by the Partnership of assets or equity
interests of a third party in an arm’s-length transaction, (ii) closing of any
acquisition by the Partnership of assets or equity interests of MPC or any of
its Affiliates or (iii) the consummation of a merger, consolidation or other
business combination of the Partnership with another entity in which the
Partnership survives and the Common Units remain outstanding to the extent any
such transaction set forth in clause (i), (ii) or (iii) above is validly
approved by the General Partner; or
(4)    The issuance of Common Units upon conversion of the Series A Preferred
Units or Series A Parity Securities.
Notwithstanding anything in this Agreement to the contrary, whenever the
issuance of a Partnership Interest or other event would require an adjustment to
the Series A Conversion Rate under one or more provisions of this Agreement,
only one adjustment shall be made to the Series A Conversion Rate in respect of
such issuance or event.
Notwithstanding anything to the contrary in Section 5.14(b)(vi)(E), unless
otherwise determined by the General Partner, no adjustment to the Series A
Conversion Rate, Series A Conversion Floor Trigger or the Series A Issue Price
shall be made with respect to any distribution or other transaction described in
Section 5.14(b)(vi)(E) if the Series A Preferred Unitholders are entitled to
participate in such distribution or transaction as if they held a number of
Common Units issuable upon conversion of the Series A Preferred Units
immediately prior to such event at the then applicable Series A Conversion Rate,
without having to convert their Series A Preferred Units.
(G)    Notwithstanding anything to the contrary in Section 5.14(b)(vii) or
elsewhere in this Agreement, in connection with any transaction pursuant to
which MPC or any of its Affiliates (other than the Partnership or any of its
Subsidiaries) would acquire, (x) all of the Partnership’s outstanding Common
Units or (y) all or substantially all of the assets of the Partnership and its
Subsidiaries, in each case including by way of merger, consolidation, or
otherwise (including any such transaction undertaken pursuant to Section 15.1),
then the Partnership shall have the right, by delivering written notice to the
Record Holders of the Series A Preferred Units, to convert all, but not less
than all, of the Series A Preferred Units into Common Units at the Series A COC
Conversion Rate effective immediately prior to the consummation of such
transaction.
(vii)    Series A Change of Control.
(A)    Subject to Section 5.14(b)(vi)(B), in the event of a Series A Cash COC
Event, the outstanding Series A Preferred Units shall be automatically
converted, without requirement of any action of the Series A Preferred
Unitholders, into Common Units immediately prior to the closing of the Series A
Cash COC Event at the Series A COC Conversion Rate.

51

--------------------------------------------------------------------------------

(B)    Subject to Section 5.14(b)(vi)(B) and Section 5.14(b)(vi)(G), at least
ten (10) Business Days prior to consummating a Series A Change of Control (other
than a Series A Cash COC Event), the Partnership shall provide written notice
thereof to the Series A Preferred Unitholders. Subject to
Section 5.14(b)(vi)(B), if a Series A Change of Control (other than a Series A
Cash COC Event) occurs, then each Series A Preferred Unitholder, with respect to
all but not less than all of its Series A Preferred Units, by notice given to
the Partnership within five (5) Business Days of the date the Partnership
provides written notice of the execution of definitive agreements that provide
for such Series A Change of Control, shall be entitled to elect one of the
following (with the understanding that any Series A Preferred Unitholder who
fails to timely provide notice of its election to the Partnership shall be
deemed to have elected the option set forth in sub-clause (1) below):
(1)    Convert all, but not less than all, of such Series A Preferred
Unitholder’s outstanding Series A Preferred Units into Common Units, at the
then-applicable Series A Conversion Rate;
(2)    If the Partnership will not be the surviving entity of such Series A
Change of Control or the Partnership will be the surviving entity but its Common
Units will cease to be listed or admitted to trading on a National Securities
Exchange, require the Partnership to use its commercially reasonable efforts to
deliver or to cause to be delivered to the Series A Preferred Unitholders, in
exchange for their Series A Preferred Units upon such Series A Change of
Control, a security in the surviving entity or the parent of the surviving
entity that has substantially similar rights, preferences and privileges as the
Series A Preferred Units, including, for the avoidance of doubt, the right to
distributions equal in amount and timing to those provided in Section 5.14(b)(i)
and a conversion rate proportionately adjusted such that the conversion of such
security in the surviving entity or parent of the surviving entity immediately
following the Series A Change of Control would entitle the Record Holder to the
number of common securities of such entity (together with a number of common
securities of equivalent value to any other assets received by holders of Common
Units in such Series A Change of Control) which, if a Series A Preferred Unit
had been converted into Common Units immediately prior to such Series A Change
of Control, such Record Holder would have been entitled to receive immediately
following such Series A Change of Control (such security in the surviving
entity, a “Series A Substantially Equivalent Unit”); provided, however, that, if
the Partnership is unable to deliver or cause to be delivered Series A
Substantially Equivalent Units to any Series A Preferred Unitholder in
connection with such Series A Change of Control, each Series A Preferred
Unitholder shall be entitled to (I) require conversion or redemption of such
Series A Preferred Units in the manner contemplated by subclause (1) or (4) of
this Section 5.14(b)(vii)(B) (at such holder’s election) or (II) convert the
Series A Preferred Units held by such Series A Preferred Unitholder immediately
prior to such Series A Change of Control into a number of Common Units at a
conversion ratio equal to the quotient of: (a) the product of (i) 160%
multiplied by (ii) the Series A Issue Price less the Series A Preferred
Unitholder’s Pro Rata portion of the sum of all cash distributions paid on all
Series A Preferred Units on or prior to the date of the Series A Change of
Control, divided by (b) an amount equal to 95% of the volume-weighted average
price of the Common Units for the thirty (30) Trading Day period prior to the
closing of the Series A Change of Control; provided that such ratio shall in no
event exceed a value per Series A Preferred Unit equal to (i) 120% of the Series
A Issue Price in the case of a Series A Change of Control occurring on or prior
to the first anniversary of

52

--------------------------------------------------------------------------------

the Series A Issuance Date, (ii) 130% of the Series A Issue Price in the case of
a Series A Change of Control occurring after the first anniversary of the Series
A Issuance Date but on or prior to the second anniversary of the Series A
Issuance Date, and (iii) 140% of the Series A Issue Price in the case of a
Series A Change of Control occurring after the second anniversary of the Series
A Issuance Date but on or prior to the third anniversary of the Series A
Issuance Date.
(3)    If the Partnership is the surviving entity of such Series A Change of
Control, continue to hold Series A Preferred Units; or
(4)    Require the Partnership to redeem the Series A Preferred Units at a price
per Series A Preferred Unit equal to 101% of the Series A Issue Price plus (x)
Series A Unpaid Cash Distributions on the applicable Series A Preferred Unit and
(y) Series A Partial Period Distributions on the applicable Series A Preferred
Unit. Any redemption pursuant to this sub-clause (4) shall, as determined by the
General Partner, be paid in cash and/or Common Units. If all or any portion of
such redemption is to be paid in Common Units, the Common Units to be issued
shall be valued at 95% of the volume-weighted average price of the Common Units
for the thirty (30) Trading Day period ending on the fifth Trading Day
immediately prior to the Series A Change of Control. No later than three Trading
Days prior to the consummation of the related Series A Change of Control, the
Partnership shall deliver a written notice to the Record Holders of the Series A
Preferred Units stating the date on which the Series A Preferred Units will be
redeemed and the Partnership’s computation of the amount of cash or Common Units
to be received by the Record Holder upon redemption of such Series A Preferred
Units. If the Partnership shall be the surviving entity of the related Series A
Change of Control, then no later than 10 Business Days following the
consummation of such Series A Change of Control, the Partnership shall remit the
applicable cash or Common Unit consideration to the Record Holders of then
outstanding Series A Preferred Units. If the Partnership shall not be the
surviving entity of the related Series A Change of Control, then the Partnership
shall remit the applicable cash or Common Unit immediately prior to the
consummation of the Series A Change of Control. The Record Holders shall deliver
to the Partnership any Certificates representing the Series A Preferred Units as
soon as practicable following the redemption. Record Holders of the Series A
Preferred Units shall retain all of the rights and privileges thereof unless and
until the consideration due to them as a result of such redemption shall be paid
in full in cash or Common Units, as applicable. After any such redemption, any
such redeemed Series A Preferred Unit shall no longer constitute an issued and
outstanding Limited Partner Interest.
(viii)    Series A Preferred Unit Transfer Restrictions.
(A)    Notwithstanding any other provision of this Section 5.14(b)(viii), each
Series A Preferred Unitholder shall be permitted to transfer any Series A
Preferred Units owned by such Series A Preferred Unitholder to any of its
Affiliates or to any other Series A Preferred Unitholder.
(B)    Without the prior written consent of the Partnership, except as
specifically provided in this Agreement and the Series A Purchase Agreement,
each Series A Preferred Unitholder shall not, (a) during the period commencing
on the Series A Issuance Date and ending on the first anniversary of the Series
A Issuance Date, offer, sell, contract to sell, sell

53

--------------------------------------------------------------------------------

any option or contract to purchase, purchase any option or contract to sell,
grant any option, right or warrant to purchase, lend, or otherwise transfer or
dispose of, directly or indirectly, any of its Series A Preferred Units, (b)
during the period commencing on the Series A Issuance Date and ending on the
second anniversary of the Series A Issuance Date, directly or indirectly engage
in any short sales or other derivative or hedging transactions with respect to
the Series A Preferred Units that are designed to, or that might reasonably be
expected to, result in the transfer to another, in whole or in part, any of the
economic consequences of ownership of any Series A Preferred Units, (c) transfer
any Series A Preferred Units to any non-U.S. resident individual, non-U.S.
corporation or partnership, or any other non-U.S. entity, including any foreign
governmental entity, including by means of any swap or other transaction or
arrangement that transfers or that is designed to, or that might reasonably be
expected to, result in the transfer to another, in whole or in part, any of the
economic consequences of ownership of any Series A Preferred Units, regardless
of whether any transaction described in clauses (a) through (c) above is to be
settled by delivery of Series A Preferred Units, Common Units or other
securities, in cash or otherwise, or (d) effect any transfer of Series A
Preferred Units or Series A Conversion Units in a manner that violates the terms
of this Agreement; provided, however, that such Series A Preferred Unitholder
may pledge all or any portion of its Series A Preferred Units to any holders of
obligations owed by the Series A Preferred Unitholders, including to the trustee
for, or representative of, such holders. Notwithstanding the foregoing, any
transferee receiving any Series A Preferred Units pursuant to this
Section 5.14(b)(viii)(B) shall agree to the restrictions set forth in this
Section 5.14(b)(viii)(B).
(C)    Following the first anniversary of the Series A Issuance Date, the Series
A Purchasers or their permitted transferees may freely transfer Series A
Preferred Units involving an underlying value of Common Units of at least
$50,000,000 (taking into account any concurrent transfers by Affiliates of such
Series A Preferred Unitholder) based on the Series A Issue Price (or such lesser
amount if it (i) constitutes the remaining holdings of such Series A Preferred
Unitholder or (ii) has been approved by the General Partner), subject to
compliance with applicable securities laws and this Agreement, including
subclauses (b) and (c) of Section 5.14(b)(viii)(B).
(D)    Notwithstanding anything to the contrary in subclause (a) of
Section 5.14(b)(viii)(B), but subject to compliance with applicable securities
laws and this Agreement, including subclauses (b) and (c) of
Section 5.14(b)(viii)(B), during the period beginning on the Series A Issuance
Date and ending on the date that is 60 days after the Series A Issuance Date
(the “Non-Affiliate Transfer Period”), Stonepeak and its Affiliates may transfer
or dispose of Series A Preferred Units to one or more non-Affiliates of
Stonepeak, subject to the consent of the Partnership as to the identity of the
transferee (which consent shall not be unreasonably withheld, conditioned or
delayed); provided, however, that (A) any transfer made pursuant to this
sentence must consist of Series A Preferred Units in an amount not less than $25
million based on the Series A Issue Price, (B) the aggregate amount of Series A
Preferred Units and rights to purchase Series A Preferred Units transferred
pursuant to this Section 5.14(b)(viii)(D) and Section 8.10 of the Series A
Purchase Agreement shall not be greater than $100 million based on the Series A
Issue Price and (C) a maximum of two transfers may be made pursuant to this
Section 5.14(b)(viii)(D) and Section 8.10 of the Series A Purchase Agreement.

54

--------------------------------------------------------------------------------

(ix)    Fully Paid and Non-Assessable. Any Series A Conversion Unit(s) delivered
pursuant to this Section 5.14 shall be validly issued, fully paid and
non-assessable (except as such non-assessability may be affected by matters
described in Sections 17-303, 17-607 and 17-804 of the Delaware Act), free and
clear of any liens, claims, rights or encumbrances other than those arising
under the Delaware Act or this Agreement or created by the holders thereof.
(x)    Notices. For the avoidance of doubt, the Partnership shall distribute to
the Record Holders of Series A Preferred Units copies of all notices, materials,

distributed to such Record Holders of such Common Units.
ARTICLE VI
ALLOCATIONS AND DISTRIBUTIONS
Section 6.1    Allocations for Capital Account Purposes. For purposes of
maintaining the Capital Accounts and in determining the rights of the Partners
among themselves, the Partnership’s items of income, gain, loss and deduction
(computed in accordance with Section 5.5(b)) for each taxable period shall be
allocated among the Partners as provided herein.
(a)        Net Income. After giving effect to the special allocations set forth
in Section 6.1(d), Net Income for each taxable period and all items of income,
gain, loss and deduction taken into account in computing Net Income for such
taxable period shall be allocated as follows:
(i)    First, to the General Partner as necessary to eliminate any deficit
balance in the General Partner’s Capital Account; and
(ii)    Second, the balance, if any, to all Unitholders (other than the Series A
Preferred Unitholders), Pro Rata.
(b)    Net Loss. After giving effect to the special allocations set forth in
Section 6.1(d), Net Loss for each taxable period and all items of income, gain,
loss and deduction taken into account in computing Net Loss for such taxable
period shall be allocated as follows:
(i)    First, to the Unitholders (other than the Series A Preferred
Unitholders), Pro Rata; provided, however, that Net Losses shall not be
allocated pursuant to this Section 6.1(b)(i) to the extent that such allocation
would cause any Unitholder to have a deficit balance in its Adjusted Capital
Account at the end of such taxable period (or increase any existing deficit
balance in its Adjusted Capital Account);
(ii)    Second, to the General Partner and the Unitholders (other than the
Series A Preferred Unitholders) to the extent of and in proportion to the
positive balances in their Adjusted Capital Accounts;

55

--------------------------------------------------------------------------------

(iii)    Third, to the Series A Preferred Unitholders, to the extent of and in
proportion to the positive balances in their Adjusted Capital Accounts; and
(iv)    The balance, if any, 100% to the General Partner.
(c)    [Reserved.]
(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 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) and other than an allocation pursuant to Section 6.1(d)(i),
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. If the amount of cash or the Net Agreed Value of
any property distributed (except cash or property distributed pursuant to
Section 12.4 or with respect to Series A Preferred Units) with respect to a
Limited Partner Unit exceeds the amount of cash or the Net Agreed Value of
property distributed with respect to another Limited Partner Unit (the amount of
the excess, an “Excess Distribution” and the Limited Partner Unit with respect
to which the greater distribution is paid, an “Excess Distribution Unit”), then
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

56

--------------------------------------------------------------------------------

with respect to such Excess Distribution Unit pursuant to this
Section 6.1(d)(iii) for the current taxable period and all previous taxable
periods is equal to the amount of the Excess Distribution.
(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, however, 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, however, 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, the 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; provided, however, that pursuant to Temporary Treasury
Regulation Section 1.707-5T(a)(2)(i), liabilities shall be

57

--------------------------------------------------------------------------------

allocated for the purposes of Treasury Regulation Section 1.707-5 in accordance
with the Partners’ interests in the Partnership’s profits, as determined by the
General Partner.
(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)    [Reserved.]
(C)    [Reserved.]
(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 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.
(E)    [Reserved.]  
(F)    [Reserved.]
(G)    [Reserved.]  
(H)    [Reserved.]
(I)    [Reserved.]
(xi)    Allocations with Respect to Series A Preferred Units.
(A)    Items of Partnership gross income and gain shall be allocated to the
Series A Preferred Unitholders, Pro Rata, until the aggregate amount of gross

58

--------------------------------------------------------------------------------

income and gain allocated to each Series A Preferred Unitholder pursuant hereto
for the current taxable period and all previous taxable periods is equal to the
cumulative amount of all cash distributions made with respect to such Series A
Preferred Unit pursuant to Section 5.14(b)(i) from the date such Series A
Preferred Unit was issued to a date 60 days after the end of the current taxable
year.
(B)    Items of Partnership gross income and gain shall be allocated to the
Series A Preferred Unitholders, Pro Rata, until the aggregate amount of gross
income and gain allocated to each Series A Preferred Unitholder pursuant hereto
for the current taxable period and all previous taxable periods is equal to the
cumulative amount of all Net Losses allocated to such Series A Preferred
Unitholder pursuant to Section 6.1(b)(iii) for all previous taxable years.
(C)    Notwithstanding any other provision of this Section 6.1 (other than the
Required Allocations), if (A) the Liquidation Date occurs prior to the
conversion of the last outstanding Series A Preferred Unit and (B) after having
made all other allocations provided for in this Section 6.1 for the taxable
period in which the Liquidation Date occurs, the Per Unit Capital Amount of each
Series A Preferred Unit would not equal or exceed the Series A Liquidation
Value, then items of income, gain, loss and deduction for such taxable period
shall instead 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 Series A Preferred Unit to equal the
Series A Liquidation Value (and no other allocation pursuant to this Agreement
shall reverse the effect of such allocation). 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
Limited Partner Units other than Series A Preferred Units to Unitholders holding
Series A Preferred Units. In the event that (i) 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
(ii) the reallocation of items for the taxable period in which the Liquidation
Date occurs as set forth above in this Section 6.1(d)(xi)(C) fails to achieve
the Per Unit Capital Amounts described above, then items of income, gain, loss
and deduction 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)(xi)(C),
cause the Per Unit Capital Amount in respect of each Series A Preferred Unit to
equal the Series A Liquidation Value.
(xii)    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

59

--------------------------------------------------------------------------------

Allocations and the related Curative Allocation not otherwise been provided in
this Section 6.1. Notwithstanding the preceding sentence, Required Allocations
relating to (1) Nonrecourse Deductions shall not be taken into account except to
the extent that there has been a decrease in Partnership Minimum Gain and (2)
Partner Nonrecourse Deductions shall not be taken into account except to the
extent that there has been a decrease in Partner Nonrecourse Debt Minimum Gain.
In exercising its discretion under this Section 6.1(d)(xii)(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)(xii)(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. Further, allocations pursuant to this Section 6.1(d)(xii)(A)
shall be deferred with respect to allocations pursuant to clauses (1) and (2)
hereof to the extent the General Partner determines that such allocations are
likely to be offset by subsequent Required Allocations.
(B)    The General Partner shall, with respect to each taxable period, (1) apply
the provisions of Section 6.1(d)(xii)(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)(xii)(A)
among the Partners in a manner that is likely to minimize such economic
distortions.
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 to be appropriate by the
General Partner (taking into account the General Partner’s discretion under
Section 6.1(d)(x)(D)); provided, however, 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

60

--------------------------------------------------------------------------------

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, for federal
income tax purposes, shall be determined for each taxable period and prorated on
a monthly basis and 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 or loss realized and
recognized other than in the ordinary course of business, 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 gain or
loss 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, agent or representative in any case
in which such nominee, agent or representative 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 the conversion of a Series A Preferred Unit into
Common Units and the adjustments pursuant to Section 5.5(d)(iii), a Capital
Account reallocation is required consistent with the principles of 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 5.14(b)(i), within 60 days following the end of
each Quarter, 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 Pro Rata to the Limited Partners as of the Record Date selected by
the General Partner. Notwithstanding any provision to the contrary contained in
this Agreement, the Partnership shall not make a distribution to any Partner on
account of its interest in the Partnership if such distribution would violate
the Delaware Act or any other applicable law. All distributions required to be
made under this Agreement shall be made subject to Sections 17-607 and 17-804 of
the Delaware Act and other applicable law, notwithstanding any other provision
of this Agreement. For the avoidance of doubt, the Series A Preferred Units and
the General Partner Interest shall not be entitled to distributions made
pursuant to this Section 6.3(a).
(b)    Notwithstanding Section 6.3(a) (but subject to the last sentence of
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 shall be applied and distributed solely in accordance
with, and subject to the terms and conditions of, Section 12.4.
(c)    Each distribution in respect of a Partnership Interest shall be paid by
the Partnership, directly or through the 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.

special distributions of cash to one or more Partners in connection with, and in
full or partial consideration of, the contribution, assignment, transfer or
conveyance of property, assets or rights or any interests therein by such
Partners to the Partnership, including, but not limited to, a distribution
pursuant to Treasury Regulation Section 1.707-5(b). For the avoidance of doubt,
such special distributions shall not be

62

--------------------------------------------------------------------------------

considered distributions of Available Cash and shall not be subject to, or
required to be distributed in accordance with, Section 6.3 or Section 12.4(c).

ARTICLE VII

to the extent permitted by law;

Member, the IPO Underwriting Agreement, the Omnibus Agreement, the Contribution
Agreement, the Employee Services Agreements, and the other agreements described
in or filed as exhibits to the IPO Registration Statement that are related to
the transactions contemplated by the IPO Registration Statement (collectively,
the “Transaction Documents”) (in each case other than this Agreement, without
giving effect to any amendments,

64

--------------------------------------------------------------------------------

supplements or restatements thereof entered into after the date such Person
becomes bound by the provisions of this Agreement); (ii) agrees that the General
Partner (on its own or on behalf of the Partnership) is authorized to execute,
deliver and perform the agreements referred to in clause (i) of this sentence
and the other agreements, acts, transactions and matters described in or
contemplated by the IPO Registration Statement on behalf of the Partnership
without any further act, approval or vote of the Partners or the other Persons
who may acquire an interest in Partnership Interests or are otherwise bound by
this Agreement; and (iii) agrees that the execution, delivery or performance by
the General Partner, any Group Member or any Affiliate of any of them of this
Agreement or any agreement authorized or permitted under this Agreement
(including the exercise by the General Partner or any Affiliate of the General
Partner of the rights accorded pursuant to Article XV) shall not constitute a
breach by the General Partner of any duty that the General Partner may owe the
Partnership or the Limited Partners or any other Persons under this Agreement
(or any other agreements) or of any duty existing at law, in equity or
otherwise.
Section 7.2    Certificate of Limited Partnership. The General Partner has
caused the Certificate of Limited Partnership to be filed with the Secretary of
State of the State of Delaware as required by the Delaware Act. The General
Partner shall use all reasonable efforts to cause to be filed such other
certificates or documents that the General Partner determines to be necessary or
appropriate for the formation, continuation, qualification and operation of a
limited partnership (or a partnership in which the limited partners have limited
liability) in the State of Delaware or any other state in which the Partnership
may elect to do business or own property. To the extent the General Partner
determines such action to be necessary or appropriate, the General Partner shall
file amendments to and restatements of the Certificate of Limited Partnership
and do all things to maintain the Partnership as a limited partnership (or a
partnership or other entity in which the limited partners have limited
liability) under the laws of the State of Delaware or of any other state in
which the Partnership may elect to do business or own property. Subject to the
terms of Section 3.3(a), the General Partner shall not be required, before or
after filing, to deliver or mail a copy of the Certificate of Limited
Partnership, any qualification document or any amendment thereto to any Limited
Partner.
Section 7.3    Restrictions on the General Partner’s Authority to Sell Assets of
the Partnership Group. Except as provided in Article XII and Article XIV, the
General Partner may not sell, exchange or otherwise dispose of all or
substantially all of the assets of the Partnership Group, taken as a whole, in a
single transaction or a series of related transactions (including by way of
merger, consolidation or other combination or sale of ownership interests of the
Partnership’s Subsidiaries) without the approval of holders of a Unit Majority;
provided, however, that this provision shall not preclude or limit the General
Partner’s ability to mortgage, pledge, hypothecate or grant a security interest
in all or substantially all of the assets of the Partnership Group and shall not
apply to any forced sale of any or all of the assets of the Partnership Group
pursuant to the foreclosure of, or other realization upon, any such encumbrance.
    

65

--------------------------------------------------------------------------------

Section 7.4    Reimbursement of and Other Payments to the General Partner.

(a)Except as provided in this Section 7.4, and elsewhere in this Agreement or in
the Omnibus Agreement, the General Partner shall not be compensated for its
services as a general partner or managing member of any Group Member.

(b)    Except as may be otherwise provided in the Omnibus Agreement, the General
Partner shall be reimbursed on a monthly basis, or such other basis as the
General Partner may determine, for (i) all direct and indirect expenses it
incurs or payments it makes on behalf of the Partnership Group (including
salary, bonus, incentive compensation and other amounts paid to any Person,
including Affiliates of the General Partner, to perform services for the
Partnership Group or for the General Partner in the discharge of its duties to
the Partnership Group), and (ii) all other expenses allocable to the Partnership
Group or otherwise incurred by the General Partner or its Affiliates in
connection with managing and operating the Partnership Group’s business and
affairs (including expenses allocated to the General Partner by its Affiliates).
The General Partner shall determine the expenses that are allocable to the
Partnership Group. Reimbursements pursuant to this Section 7.4 shall be in
addition to any reimbursement to the General Partner as a result of
indemnification pursuant to Section 7.7. Any allocation of expenses to the
Partnership by the General Partner in a manner consistent with its or its
Affiliates’ past business practices and, in the case of assets regulated by
FERC, then applicable accounting and allocation methodologies generally
permitted by FERC for rate-making purposes (or in the absence of then-applicable
methodologies permitted by FERC, consistent with the most-recently applicable
methodologies), shall be deemed to have been made in good faith.
(c)    The General Partner, without the approval of the Limited Partners (who
shall have no right to vote in respect thereof), may propose and adopt on behalf
of the Partnership employee benefit plans, employee programs and employee
practices (including plans, programs and practices involving the issuance of
Partnership Interests or Derivative Partnership Interests), or cause the
Partnership to issue Partnership Interests or Derivative Partnership Interests
in connection with, or pursuant to, any employee benefit plan, employee program
or employee practice maintained or sponsored by the General Partner or any of
its Affiliates in each case for the benefit of officers, employees and directors
of the General Partner or any of its Affiliates, in respect of services
performed, directly or indirectly, for the benefit of the Partnership Group. The
Partnership agrees to issue and sell to the General Partner or any of its
Affiliates any Partnership Interests that the General Partner or such Affiliates
are obligated to provide to any officers, employees, consultants and directors
pursuant to any such employee benefit plans, employee programs or employee
practices. Expenses incurred by the General Partner in connection with any such
plans, programs and practices (including the net cost to the General Partner or
such Affiliates of Partnership Interests purchased by the General Partner or
such Affiliates from the Partnership to fulfill options or awards under such
plans, programs and practices) shall be reimbursed in accordance with
Section 7.4(b). Any and all obligations of the General Partner under any
employee benefit plans, employee programs or employee practices adopted by the
General Partner as permitted by this Section 7.4(c) shall constitute obligations
of the General Partner hereunder and shall be assumed by any successor General
Partner approved pursuant to Section 11.1 or Section 11.2 or the transferee of
or successor to all of the General Partner’s General Partner Interest pursuant
to Section 4.6.

66

--------------------------------------------------------------------------------

(d)    The General Partner and its Affiliates may charge any member of the
Partnership Group a management fee to the extent necessary to allow the
Partnership Group to reduce the amount of any state franchise or income tax or
any tax based upon the revenues or gross margin of any member of the Partnership
Group if the tax benefit produced by the payment of such management fee or fees
exceeds the amount of such fee or fees.
(e)    The General Partner and its Affiliates may enter into an agreement to
provide services to any Group Member for a fee or otherwise than for cost.
Section 7.5    Outside Activities.
(a)        The General Partner, for so long as it is the General Partner of the
Partnership (i) agrees that its sole business will be to act as a general
partner or managing member, as the case may be, of the Partnership and any other
partnership or limited liability company of which the Partnership is, directly
or indirectly, a partner or member and to undertake activities that are
ancillary or related thereto (including being a Limited Partner in the
Partnership) and (ii) shall not engage in any business or activity or incur any
debts or liabilities except in connection with or incidental to (A) its
performance as general partner or managing member, if any, of one or more Group
Members or as described in or contemplated by the IPO Registration Statement,
(B) the acquiring, owning or disposing of debt securities or equity interests in
any Group Member, (C) the guarantee of, and mortgage, pledge, or encumbrance of
any or all of its assets in connection with, any indebtedness of any Group
Member or (D) the performance of its obligations under the Omnibus Agreement.
(b)    Subject to the terms of Section 7.5(c), each Unrestricted Person (other
than the General Partner) shall have the right to engage in businesses of every
type and description and other activities for profit and to engage in and
possess an interest in other business ventures of any and every type or
description, whether in businesses engaged in or anticipated to be engaged in by
any Group Member, independently or with others, including business interests and
activities in direct competition with the business and activities of any Group
Member, and none of the same shall constitute a breach of this Agreement or any
duty otherwise existing at law, in equity or otherwise, to any Group Member or
any Partner. None of any Group Member, any Limited Partner or any other Person
shall have any rights by virtue of this Agreement, any Group Member Agreement,
or the partnership relationship established hereby in any business ventures of
any Unrestricted Person.
(c)    Subject to the terms of Section 7.5(a) and Section 7.5(b), but otherwise
notwithstanding anything to the contrary in this Agreement, (i) the engaging in
competitive activities by any Unrestricted Person (other than the General
Partner) in accordance with the provisions of this Section 7.5 is hereby
approved by the Partnership and all Partners, (ii) it shall be deemed not to be
a breach of any duty or any other obligation of any type whatsoever of the
General Partner or any other Unrestricted Person for the Unrestricted Persons
(other than the General Partner) to engage in such business interests and
activities in preference to or to the exclusion of the Partnership and (iii) the
Unrestricted Persons shall have no obligation hereunder or as a result of any
duty otherwise existing at law, in equity or otherwise, to present business
opportunities to the Partnership. Notwithstanding anything to the contrary in
this Agreement or any duty otherwise existing at law or in equity, the doctrine
of corporate opportunity, or any

67

--------------------------------------------------------------------------------

analogous doctrine, shall not apply to any Unrestricted Person (including the
General Partner). No Unrestricted Person (including the General Partner) who
acquires knowledge of a potential transaction, agreement, arrangement or other
matter that may be an opportunity for the Partnership, shall have any duty to
communicate or offer such opportunity to the Partnership, and such Unrestricted
Person (including the General Partner) shall not be liable to the Partnership,
to any Limited Partner or any other Person bound by this Agreement for breach of
any duty by reason of the fact that such Unrestricted Person (including the
General Partner) pursues or acquires for itself, directs such opportunity to
another Person or does not communicate such opportunity or information to the
Partnership, provided that such Unrestricted Person does not engage in such
business or activity using confidential or proprietary information provided by
or on behalf of the Partnership to such Unrestricted Person.
(d)    The General Partner and each of its Affiliates may acquire Limited
Partner Units or other Partnership Interests in addition to those acquired on
the Closing Date and, except as otherwise provided in this Agreement, shall be
entitled to exercise, at their option, all rights relating to all Limited
Partner Units and/or other Partnership Interests acquired by them. The term
“Affiliates” when used in this Section 7.5(d) with respect to the General
Partner shall not include any Group Member.
Section 7.6    Loans from the General Partner; Loans or Contributions from the
Partnership or Group Members.
(a)        The General Partner or any of its Affiliates may lend to any Group
Member, and any Group Member may borrow from the General Partner or any of its
Affiliates, funds needed or desired by the Group Member for such periods of time
and in such amounts as the General Partner may determine; provided, however,
that in any such case the lending party may not charge the borrowing party
interest at a rate greater than the rate that would be charged the borrowing
party or impose terms less favorable to the borrowing party than would be
charged or imposed on the borrowing party by unrelated lenders on comparable
loans made on an arm’s-length basis (without reference to the lending party’s
financial abilities or guarantees), all as determined by the General Partner.
The borrowing party shall reimburse the lending party for any costs (other than
any additional interest costs) incurred by the lending party in connection with
the borrowing of such funds. For purposes of this Section 7.6(a) and
Section 7.6(b), the term “Group Member” shall include any Affiliate of a Group
Member that is controlled by the Group Member.
(b)    The Partnership may lend or contribute to any Group Member, and any Group
Member may borrow from the Partnership, funds on terms and conditions determined
by the General Partner. No Group Member may lend funds to the General Partner or
any of its Affiliates (other than another Group Member).
(c)    No borrowing by any Group Member or the approval thereof by the General
Partner shall be deemed to constitute a breach of any duty, expressed or
implied, of the General Partner or its Affiliates to the Partnership or the
Limited Partners existing hereunder, or existing at law, in equity or otherwise
by reason of the fact that the purpose or effect of such borrowing is directly
or indirectly to enable distributions to the General Partner or its Affiliates

68

--------------------------------------------------------------------------------

(including in their capacities as Limited Partners) to exceed the General
Partner’s Percentage Interest of the total amount distributed to all Partners.
Section 7.7    Indemnification.
(a)        To the fullest extent permitted by law but subject to the limitations
expressly provided in this Agreement, all Indemnitees shall be indemnified and
held harmless by the Partnership from and against any and all losses, claims,
damages, liabilities, joint or several, expenses (including legal fees and
expenses), judgments, fines, penalties, interest, settlements or other amounts
arising from any and all threatened, pending or completed claims, demands,
actions, suits or proceedings, whether civil, criminal, administrative or
investigative, and whether formal or informal and including appeals, in which
any Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise, by reason of its status as an Indemnitee and acting (or refraining to
act) in such capacity on behalf of or for the benefit of the Partnership;
provided, that the Indemnitee shall not be indemnified and held harmless
pursuant to this Agreement if there has been a final and non-appealable judgment
entered by a court of competent jurisdiction determining that, in respect of the
matter for which the Indemnitee is seeking indemnification pursuant to this
Agreement, the Indemnitee acted in bad faith or engaged in intentional fraud,
willful misconduct or, in the case of a criminal matter, acted with knowledge
that the Indemnitee’s conduct was unlawful; provided, further, no
indemnification pursuant to this Section 7.7 shall be available to any Affiliate
of the General Partner (other than a Group Member), or to any other Indemnitee,
with respect to any such Affiliate’s obligations pursuant to the Transaction
Documents. Any indemnification pursuant to this Section 7.7 shall be made only
out of the assets of the Partnership, it being agreed that the General Partner
shall not be personally liable for such indemnification and shall have no
obligation to contribute or loan any monies or property to the Partnership to
enable it to effectuate such indemnification.
(b)    To the fullest extent permitted by law, expenses (including legal fees
and expenses) incurred by an Indemnitee who is indemnified pursuant to
Section 7.7(a) in defending any claim, demand, action, suit or proceeding shall,
from time to time, be advanced by the Partnership prior to a final and
non-appealable judgment entered by a court of competent jurisdiction determining
that, in respect of the matter for which the Indemnitee is seeking
indemnification pursuant to this Section 7.7, the Indemnitee is not entitled to
be indemnified upon receipt by the Partnership of any undertaking by or on
behalf of the Indemnitee to repay such amount if it shall be ultimately
determined that the Indemnitee is not entitled to be indemnified as authorized
by this Section 7.7.
(c)    The indemnification provided by this Section 7.7 shall be in addition to
any other rights to which an Indemnitee may be entitled under any agreement,
pursuant to any vote of the holders of Voting Eligible Limited Partner
Interests, as a matter of law, in equity or otherwise, both as to actions in the
Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity
(including any capacity under the IPO Underwriting Agreement), and shall
continue as to an Indemnitee who has ceased to serve in such capacity and shall
inure to the benefit of the heirs, successors, assigns and administrators of the
Indemnitee.
(d)    The Partnership may purchase and maintain (or reimburse the General
Partner or its Affiliates for the cost of) insurance, on behalf of the General
Partner, its Affiliates

69

--------------------------------------------------------------------------------

and such other Persons as the General Partner shall determine, against any
liability that may be asserted against, or expense that may be incurred by, such
Person in connection with the Partnership’s activities or such Person’s
activities on behalf of the Partnership, regardless of whether the Partnership
would have the power to indemnify such Person against such liability under the
provisions of this Agreement.
(e)    For purposes of this Section 7.7, the Partnership shall be deemed to have
requested an Indemnitee to serve as fiduciary of an employee benefit plan
whenever the performance by it of its duties to the Partnership also imposes
duties on, or otherwise involves services by, it to the plan or participants or
beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect
to an employee benefit plan pursuant to applicable law shall constitute “fines”
within the meaning of Section 7.7(a); and action taken or omitted by it with
respect to any employee benefit plan in the performance of its duties for a
purpose reasonably believed by it to be in the best interest of the participants
and beneficiaries of the plan shall be deemed to be for a purpose that is in the
best interests of the Partnership.
(f)    In no event may an Indemnitee subject the Limited Partners to personal
liability by reason of the indemnification provisions set forth in this
Agreement.
(g)    An Indemnitee shall not be denied indemnification in whole or in part
under this Section 7.7 because the Indemnitee had an interest in the transaction
with respect to which the indemnification applies if the transaction was
otherwise permitted by the terms of this Agreement.
(h)    The provisions of this Section 7.7 are for the benefit of the Indemnitees
and their heirs, successors, assigns, executors and administrators and shall not
be deemed to create any rights for the benefit of any other Persons.
(i)    No amendment, modification or repeal of this Section 7.7 or any provision
hereof shall in any manner terminate, reduce or impair the right of any past,
present or future Indemnitee to be indemnified by the Partnership, nor the
obligations of the Partnership to indemnify any such Indemnitee under and in
accordance with the provisions of this Section 7.7 as in effect immediately
prior to such amendment, modification or repeal with respect to claims arising
from or relating to matters occurring, in whole or in part, prior to such
amendment, modification or repeal, regardless of when such claims may arise or
be asserted.
Section 7.8    Liability of Indemnitees.
(a)        Notwithstanding anything to the contrary set forth in this Agreement,
no Indemnitee shall be liable for monetary damages to the Partnership, the
Limited Partners, or any other Persons who are bound by this Agreement for
losses sustained or liabilities incurred as a result of any act or omission of
an Indemnitee unless there has been a final and non-appealable judgment entered
by a court of competent jurisdiction determining that, in respect of the matter
in question, the Indemnitee acted in bad faith or engaged in intentional fraud,
willful misconduct or, in the case of a criminal matter, acted with knowledge
that the Indemnitee’s conduct was criminal.

70

--------------------------------------------------------------------------------

(b)    The General Partner may exercise any of the powers granted to it by this
Agreement and perform any of the duties imposed upon it hereunder either
directly or by or through its agents, and the General Partner shall not be
responsible for any misconduct or negligence on the part of any such agent
appointed by the General Partner in good faith.
(c)    To the extent that, at law or in equity, an Indemnitee has duties
(including fiduciary duties) and liabilities relating thereto to the Partnership
or to the Partners, the General Partner and any other Indemnitee acting in
connection with the Partnership’s business or affairs shall not be liable to the
Partnership or to any Partner or to any other Persons who are bound by this
Agreement for its good faith reliance on the provisions of this Agreement.
(d)    Any amendment, modification or repeal of this Section 7.8 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the liability of the Indemnitees under this Section 7.8 as in
effect immediately prior to such amendment, modification or repeal with respect
to claims arising from or relating to matters occurring, in whole or in part,
prior to such amendment, modification or repeal, regardless of when such claims
may arise or be asserted.
Section 7.9    Resolution of Conflicts of Interest; Standards of Conduct and
Modification of Duties.
(a)        Unless otherwise expressly provided in this Agreement or any Group
Member Agreement, whenever a potential conflict of interest exists or arises
between the General Partner or any of its Affiliates, on the one hand, and the
Partnership, any Group Member or any Partner, on the other, any resolution or
course of action by the General Partner or its Affiliates in respect of such
conflict of interest shall be permitted and deemed approved by all Partners, and
shall not constitute a breach of this Agreement, of any Group Member Agreement,
of any agreement contemplated herein or therein, or of any duty stated or
implied by law or equity, if the resolution or course of action in respect of
such conflict of interest is (i) approved by Special Approval, (ii) approved by
the vote of a majority of the Voting Eligible Common Units (excluding Common
Units owned by the General Partner and its Affiliates) and Series A Preferred
Units voting together as a single class, (iii) on terms no less favorable to the
Partnership than those generally being provided to or available from unrelated
third parties or (iv) fair and reasonable to the Partnership, taking into
account the totality of the relationships between the parties involved
(including other transactions that may be particularly favorable or advantageous
to the Partnership). The General Partner shall be authorized but not required in
connection with its resolution of such conflict of interest to seek Special
Approval or Unitholder approval of such resolution, and the General Partner may
also adopt a resolution or course of action that has not received Special
Approval or Unitholder approval. Whenever the General Partner makes a
determination to refer any potential conflict of interest to the Conflicts
Committee for Special Approval, seek Unitholder approval or adopt a resolution
or course of action that has not received Special Approval or Unitholder
approval, then the General Partner shall be entitled, to the fullest extent
permitted by law, to make such determination or to take or decline to take such
other action free of any duty or obligation whatsoever to the Partnership or any
Limited Partner, and the General Partner shall not, to the fullest extent
permitted by law, be required to act in good faith or pursuant to any other
standard or duty imposed by this Agreement, any Group Member Agreement, any
other agreement contemplated hereby or under

71

--------------------------------------------------------------------------------

the Delaware Act or any other law, rule or regulation or at equity, and the
General Partner in making such determination or taking or declining to take such
other action shall be permitted to do so in its sole and absolute discretion. If
Special Approval is sought, then it shall be presumed that, in making its
decision, the Conflicts Committee acted in good faith, and if the Board of
Directors determines that the resolution or course of action taken with respect
to a conflict of interest satisfies either of the standards set forth in clauses
(iii) or (iv) above or that a director satisfies the eligibility requirements to
be a member of the Conflicts Committee, then it shall be presumed that, in
making its decision, the Board of Directors acted in good faith. In any
proceeding brought by any Limited Partner or by or on behalf of such Limited
Partner or any other Limited Partner or the Partnership challenging any action
by the Conflicts Committee with respect to any matter referred to the Conflicts
Committee for Special Approval by the General Partner, any determination by the
Board of Directors that the resolution or course of action taken with respect to
a conflict of interest satisfies either of the standards set forth in clauses
(iii) or (iv) above or any determination by the Board of Directors that a
director satisfies the eligibility requirements to be a member of the Conflicts
Committee, the Person bringing or prosecuting such proceeding shall have the
burden of overcoming the presumption that the Conflicts Committee or the Board
of Directors, as applicable, acted in good faith. Notwithstanding anything to
the contrary in this Agreement or any duty otherwise existing at law or equity,
the existence of the conflicts of interest described in the IPO Registration
Statement are hereby approved by all Partners and shall not constitute a breach
of this Agreement or any such duty.
(b)    Whenever the General Partner or the Board of Directors, or any committee
thereof (including the Conflicts Committee), makes a determination or takes or
declines to take any other action, or any Affiliate of the General Partner
causes the General Partner to do so, in its capacity as the general partner of
the Partnership as opposed to in its individual capacity, whether under this
Agreement, any Group Member Agreement or any other agreement contemplated hereby
or otherwise, then, unless another express standard is provided for in this
Agreement, the General Partner, the Board of Directors or such committee or such
Affiliates causing the General Partner to do so, shall make such determination
or take or decline to take such other action in good faith and shall not be
subject to any other or different standards (including fiduciary standards)
imposed by this Agreement, any Group Member Agreement, any other agreement
contemplated hereby or under the Delaware Act or any other law, rule or
regulation or at equity. A determination or other action or inaction will
conclusively be deemed to be in “good faith” for all purposes of this Agreement,
if the Person or Persons making such determination or taking or declining to
take such other action subjectively believe that the determination or other
action or inaction is not adverse to the best interests of the Partnership
Group.
(c)    Whenever the General Partner makes a determination or takes or declines
to take any other action, or any of its Affiliates causes it to do so, in its
individual capacity as opposed to in its capacity as the general partner of the
Partnership, whether under this Agreement, any Group Member Agreement or any
other agreement contemplated hereby or otherwise, then the General Partner, or
such Affiliates causing it to do so, are entitled, to the fullest extent
permitted by law, to make such determination or to take or decline to take such
other action free of any duty or obligation whatsoever to the Partnership or any
Limited Partner, and the General Partner, or such Affiliates causing it to do
so, shall not, to the fullest extent permitted by law, be required to act in
good faith or pursuant to any other standard imposed by

72

--------------------------------------------------------------------------------

this Agreement, any Group Member Agreement, any other agreement contemplated
hereby or under the Delaware Act or any other law, rule or regulation or at
equity, and the Person or Persons making such determination or taking or
declining to take such other action shall be permitted to do so in their sole
and absolute discretion. By way of illustration and not of limitation, whenever
the phrase, “the General Partner at its option,” or some variation of that
phrase, is used in this Agreement, it indicates that the General Partner is
acting in its individual capacity. For the avoidance of doubt, whenever the
General Partner votes or transfers its Partnership Interests, or refrains from
voting or transferring its Partnership Interests, it shall be acting in its
individual capacity.
(d)    The General Partner’s organizational documents may provide that
determinations to take or decline to take any action in its individual, rather
than representative, capacity may or shall be determined by its members, if the
General Partner is a limited liability company, stockholders, if the General
Partner is a corporation, or the members or stockholders of the General
Partner’s general partner, if the General Partner is a partnership.
(e)    Notwithstanding anything to the contrary in this Agreement, the General
Partner and its Affiliates shall have no duty or obligation, express or implied,
to (i) sell or otherwise dispose of any asset of the Partnership Group other
than in the ordinary course of business or (ii) permit any Group Member to use
any facilities or assets of the General Partner and its Affiliates, except as
may be provided in contracts entered into from time to time specifically dealing
with such use. Any determination by the General Partner or any of its Affiliates
to enter into such contracts shall be at its option.
(f)    Except as expressly set forth in this Agreement or required by the
Delaware Act, neither the General Partner nor any other Indemnitee shall have
any duties or liabilities, including fiduciary duties, to the Partnership or any
Limited Partner and the provisions of this Agreement, to the extent that they
restrict, eliminate or otherwise modify the duties and liabilities, including
fiduciary duties, of the General Partner or any other Indemnitee otherwise
existing at law or in equity, are agreed by the Partners to replace such other
duties and liabilities of the General Partner or such other Indemnitee.
(g)    The Unitholders hereby authorize the General Partner, on behalf of the
Partnership as a partner or member of a Group Member, to approve actions by the
general partner or managing member of such Group Member similar to those actions
permitted to be taken by the General Partner pursuant to this Section 7.9.
Section 7.10    Other Matters Concerning the General Partner and Other
Indemnitees.
(a)        The General Partner and any other Indemnitee may rely and shall be
protected in acting or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, bond,
debenture or other paper or document believed by it to be genuine and to have
been signed or presented by the proper party or parties.

73

--------------------------------------------------------------------------------

(b)    The General Partner and any other Indemnitee may consult with legal
counsel, accountants, appraisers, management consultants, investment bankers and
other consultants and advisers selected by it, and any act taken or omitted to
be taken in reliance upon the advice or opinion (including an Opinion of
Counsel) of such Persons as to matters that the General Partner or such
Indemnitee, respectively, reasonably believes to be within such Person’s
professional or expert competence shall be conclusively presumed to have been
done or omitted in good faith and in accordance with such opinion.
(c)    The General Partner shall have the right, in respect of any of its powers
or obligations hereunder, to act through any of its duly authorized officers, a
duly appointed attorney or attorneys-in-fact or the duly authorized officers of
the Partnership or any Group Member.
Section 7.11    Purchase or Sale of Partnership Interests. The General Partner
may cause the Partnership to purchase or otherwise acquire Partnership Interests
or Derivative Partnership Interests. As long as Partnership Interests are held
by any Group Member, such Partnership Interests shall not be considered
outstanding for any purpose, except as otherwise provided herein. The General
Partner or any Affiliate of the General Partner may also purchase or otherwise
acquire and sell or otherwise dispose of Partnership Interests for its own
account, subject to the provisions of Articles IV and X.
Section 7.12    Registration Rights of the General Partner and its Affiliates.
(a)    Demand Registration. Upon receipt of a Notice from any Holder at any time
after the 180th day after the Closing Date, the Partnership shall file with the
Commission as promptly as reasonably practicable a registration statement under
the Securities Act (each, a “Registration Statement”) providing for the resale
of the Registrable Securities, which may, at the option of the Holder giving
such Notice, be a Registration Statement that provides for the resale of the
Registrable Securities from time to time pursuant to Rule 415 under the
Securities Act. The Partnership shall not be required pursuant to this
Section 7.12(a) to file more than one Registration Statement in any twelve-month
period nor to file more than three Registration Statements in the aggregate. The
Partnership shall use commercially reasonable efforts to cause such Registration
Statement to become effective as soon as reasonably practicable after the
initial filing of the Registration Statement and to remain effective and
available for the resale of the Registrable Securities by the Selling Holders
named therein until the earlier of (i) six months following such Registration
Statement’s effective date and (ii) the date on which all Registrable Securities
covered by such Registration Statement have been sold. In the event one or more
Holders request in a Notice to dispose of a number of Registrable Securities
that such Holder or Holders reasonably anticipates will result in gross proceeds
of at least $30,000,000 in the aggregate pursuant to a Registration Statement in
an Underwritten Offering, the Partnership shall retain underwriters that are
reasonably acceptable to such Selling Holders in order to permit such Selling
Holders to effect such disposition through an Underwritten Offering; provided,
however, that the Partnership shall have the exclusive right to select the
bookrunning managers. The Partnership and such Selling Holders shall enter into
an underwriting agreement in customary form that is reasonably acceptable to the
Partnership and take all reasonable actions as are requested by the managing
underwriters to facilitate the Underwritten Offering and sale of Registrable
Securities therein. No Holder may participate in the Underwritten Offering
unless it

74

--------------------------------------------------------------------------------

agrees to sell its Registrable Securities covered by the Registration Statement
on the terms and conditions of the underwriting agreement and completes and
delivers all necessary documents and information reasonably required under the
terms of such underwriting agreement. In the event that the managing underwriter
of such Underwritten Offering advises the Partnership and the Holder in writing
that in its opinion the inclusion of all or some Registrable Securities would
adversely and materially affect the timing or success of the Underwritten
Offering, the amount of Registrable Securities that each Selling Holder
requested be included in such Underwritten Offering shall be reduced on a Pro
Rata basis to the aggregate amount that the managing underwriter deems will not
have such material and adverse effect. Any Holder may withdraw from such
Underwritten Offering by notice to the Partnership and the managing underwriter;
provided such notice is delivered prior to the launch of such Underwritten
Offering.

(b)    Piggyback Registration. At any time after the 180th day after the Closing
Date, if the Partnership shall propose to file a Registration Statement (other
than pursuant to a demand made pursuant to Section 7.12(a)) for an offering of
Partnership Interests for cash (other than an offering relating solely to an
employee benefit plan, an offering relating to a transaction on Form S-4 or an
offering on any registration statement that does not permit secondary sales),
the Partnership shall notify all Holders of such proposal at least five business
days before the proposed filing date. The Partnership shall use commercially
reasonable efforts to include such number of Registrable Securities held by any
Holder in such Registration Statement as each Holder shall request in a Notice
received by the Partnership within two business days of such Holder’s receipt of
the notice from the Partnership. If the Registration Statement about which the
Partnership gives notice under this Section 7.12(b) is for an Underwritten
Offering, then any Holder’s ability to include its desired amount of Registrable
Securities in such Registration Statement shall be conditioned on such Holder’s
inclusion of all such Registrable Securities in the Underwritten Offering;
provided that, in the event that the managing underwriter of such Underwritten
Offering advises the Partnership and the Holder in writing that in its opinion
the inclusion of all or some Registrable Securities would adversely and
materially affect the timing or success of the Underwritten Offering, the amount
of Registrable Securities that each Selling Holder requested be included in such
Underwritten Offering shall be reduced on a Pro Rata basis to the aggregate
amount that the managing underwriter deems will not have such material and
adverse effect. In connection with any such Underwritten Offering, the
Partnership and the Selling Holders involved shall enter into an underwriting
agreement in customary form that is reasonably acceptable to the Partnership and
take all reasonable actions as are requested by the managing underwriters to
facilitate the Underwritten Offering and sale of Registrable Securities therein.
No Holder may participate in the Underwritten Offering unless it agrees to sells
its Registrable Securities covered by the Registration Statement on the terms
and conditions of the underwriting agreement and completes and delivers all
necessary documents and information reasonably required under the terms of such
underwriting agreement. Any Holder may withdraw from such Underwritten Offering
by notice to the Partnership and the managing underwriter; provided such notice
is delivered prior to the launch of such Underwritten Offering. The Partnership
shall have the right to terminate or withdraw any Registration Statement or
Underwritten Offering initiated by it under this Section 7.12(b) prior to the
effective date of the Registration Statement or the pricing date of the
Underwritten Offering, as applicable.

75

--------------------------------------------------------------------------------

(c)    Sale Procedures. In connection with its obligations under this
Section 7.12, the Partnership shall:
(i)    furnish to each Selling Holder (A) as far in advance as reasonably
practicable before filing a Registration Statement or any supplement or
amendment thereto, upon request, copies of reasonably complete drafts of all
such documents proposed to be filed (including exhibits and each document
incorporated by reference therein to the extent then required by the rules and
regulations of the Commission), and provide each such Selling Holder the
opportunity to object to any information pertaining to such Selling Holder and
its plan of distribution that is contained therein and make the corrections
reasonably requested by such Selling Holder with respect to such information
prior to filing a Registration Statement or supplement or amendment thereto, and
(B) such number of copies of such Registration Statement and the prospectus
included therein and any supplements and amendments thereto as such Persons may
reasonably request in order to facilitate the public sale or other disposition
of the Registrable Securities covered by such Registration Statement; provided,
however, that the Partnership will not have any obligation to provide any
document pursuant to clause (B) hereof that is available on the Commission’s
website;
(ii)    if applicable, use its commercially reasonable efforts to register or
qualify the Registrable Securities covered by a Registration Statement under the
securities or blue sky laws of such jurisdictions as the Selling Holders or, in
the case of an Underwritten Offering, the managing underwriter, shall reasonably
request; provided, however, that the Partnership will not be required to qualify
generally to transact business in any jurisdiction where it is not then required
to so qualify or to take any action that would subject it to general service of
process in any jurisdiction where it is not then so subject;
(iii)    promptly notify each Selling Holder and each underwriter, at any time
when a prospectus is required to be delivered under the Securities Act, of (A)
the filing of a Registration Statement or any prospectus or prospectus
supplement to be used in connection therewith, or any amendment or supplement
thereto, and, with respect to such Registration Statement or any post-effective
amendment thereto, when the same has become effective; and (B) any written
comments from the Commission with respect to any Registration Statement or any
document incorporated by reference therein and any written request by the
Commission for amendments or supplements to a Registration Statement or any
prospectus or prospectus supplement thereto;
(iv)    immediately notify each Selling Holder and each underwriter, at any time
when a prospectus is required to be delivered under the Securities Act, of (A)
the occurrence of any event or existence of any fact (but not a description of
such event or fact) as a result of which the prospectus or prospectus supplement
contained in a Registration Statement, as then in effect, includes an untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading (in
the case of the prospectus contained therein, in the light of the circumstances
under which a statement is made); (B) the issuance or threat of issuance by the
Commission of any stop order suspending the effectiveness of a Registration
Statement, or the initiation of any proceedings for that purpose; or (C) the
receipt by the Partnership of any notification with respect to the suspension of
the qualification of any Registrable Securities for sale under the applicable

76

--------------------------------------------------------------------------------

securities or blue sky laws of any jurisdiction. Following the provision of such
notice, subject to Section 7.12(f), the Partnership agrees to, as promptly as
practicable, amend or supplement the prospectus or prospectus supplement or take
other appropriate action so that the prospectus or prospectus supplement does
not include an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in the light of the circumstances then existing and to take such
other reasonable action as is necessary to remove a stop order, suspension,
threat thereof or proceedings related thereto; and
(v)    enter into customary agreements and take such other actions as are
reasonably requested by the Selling Holders or the underwriters, if any, in
order to expedite or facilitate the disposition of the Registrable Securities,
including the provision of comfort letters and legal opinions as are customary
in such securities offerings.
(d)    Suspension. Each Selling Holder, upon receipt of notice from the
Partnership of the happening of any event of the kind described in
Section 7.12(c)(iv), shall forthwith discontinue disposition of the Registrable
Securities by means of a prospectus or prospectus supplement until such Selling
Holder’s receipt of the copies of the supplemented or amended prospectus
contemplated by such subsection or until it is advised in writing by the
Partnership that the use of the prospectus may be resumed, and has received
copies of any additional or supplemental filings incorporated by reference in
the prospectus.
(e)    Expenses. Except as set forth in an underwriting agreement for the
applicable Underwritten Offering or as otherwise agreed between a Selling Holder
and the Partnership, all costs and expenses of a Registration Statement filed or
an Underwritten Offering that includes Registrable Securities pursuant to this
Section 7.12 (other than underwriting discounts and commissions on Registrable
Securities and fees and expenses of counsel and advisors to Selling Holders)
shall be paid by the Partnership.
(f)    Delay Right. Notwithstanding anything to the contrary herein, if the
General Partner determines that the Partnership’s compliance with its
obligations in this Section 7.12 would be detrimental to the Partnership because
such registration would (x) materially interfere with a significant acquisition,
reorganization or other similar transaction involving the Partnership, (y)
require premature disclosure of material information that the Partnership has a
bona fide business purpose for preserving as confidential or (z) render the
Partnership unable to comply with requirements under applicable securities laws,
then the Partnership shall have the right to postpone compliance with such
obligations for a period of not more than six months; provided, however, that
such right may not be exercised more than twice in any 24-month period.
(g)    Indemnification.
(i)    In addition to and not in limitation of the Partnership’s obligation
under Section 7.7, the Partnership shall, to the fullest extent permitted by
law, indemnify and hold harmless each Selling Holder, its officers, directors
and each Person who controls the Holder (within the meaning of the Securities
Act) and any agent thereof (collectively, “Indemnified Persons”) from and
against any and all losses, claims, damages, liabilities, joint

77

--------------------------------------------------------------------------------

or several, expenses (including legal fees and expenses), judgments, fines,
penalties, interest, settlements or other amounts arising from any and all
claims, demands, actions, suits or proceedings, whether civil, criminal,
administrative or investigative, in which any Indemnified Person may be
involved, or is threatened to be involved, as a party or otherwise, under the
Securities Act or otherwise (hereinafter referred to in this Section 7.12(g) as
a “claim” and in the plural as “claims”) based upon, arising out of or resulting
from any untrue statement or alleged untrue statement of any material fact
contained in any Registration Statement, preliminary prospectus, final
prospectus or issuer free writing prospectus under which any Registrable
Securities were registered or sold under the Securities Act, or arising out of,
based upon or resulting from the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading; provided, however, that the Partnership shall not be
liable to any Indemnified Person to the extent that any such claim arises out
of, is based upon or results from an untrue statement or alleged untrue
statement or omission or alleged omission made in such Registration Statement,
preliminary prospectus, final prospectus or issuer free writing prospectus in
reliance upon and in conformity with written information furnished to the
Partnership by or on behalf of such Indemnified Person specifically for use in
the preparation thereof.
(ii)    Each Selling Holder shall, to the fullest extent permitted by law,
indemnify and hold harmless the Partnership, the General Partner, the General
Partner’s officers and directors and each Person who controls the Partnership or
the General Partner (within the meaning of the Securities Act) and any agent
thereof to the same extent as the foregoing indemnity from the Partnership to
the Selling Holders, but only with respect to information regarding such Selling
Holder furnished in writing by or on behalf of such Selling Holder expressly for
inclusion in a Registration Statement, prospectus or free writing prospectus
relating to the Registrable Securities held by such Selling Holder.
(iii)    The provisions of this Section 7.12(g) shall be in addition to any
other rights to indemnification or contribution that a Person entitled to
indemnification under this Section 7.12(g) may have pursuant to law, equity,
contract or otherwise.
(h)    Specific Performance. Damages in the event of breach of Section 7.12 by a
party hereto may be difficult, if not impossible, to ascertain, and it is
therefore agreed that each party, in addition to and without limiting any other
remedy or right it may have, will have the right to seek an injunction or other
equitable relief in any court of competent jurisdiction, enjoining any such
breach, and enforcing specifically the terms and provisions hereof, and each of
the parties hereto hereby waives, to the fullest extent permitted by law, any
and all defenses it may have on the ground of lack of jurisdiction or competence
of the court to grant such an injunction or other equitable relief. The
existence of this right will not preclude any such party from pursuing any other
rights and remedies at law or in equity that such party may have.
Section 7.13    Reliance by Third Parties. Notwithstanding anything to the
contrary in this Agreement, any Person dealing with the Partnership shall be
entitled to assume that the General Partner and any officer of the General
Partner authorized by the General Partner to act on behalf of and in the name of
the Partnership has full power and authority to encumber, sell or otherwise use
in any manner any and all assets of the Partnership and to enter into any
authorized contracts on behalf of the Partnership, and such Person shall be
entitled to deal with the General

78

--------------------------------------------------------------------------------

Partner or any such officer as if it were the Partnership’s sole party in
interest, both legally and beneficially. Each Limited Partner hereby waives, to
the fullest extent permitted by law, any and all defenses or other remedies that
may be available against such Person to contest, negate or disaffirm any action
of the General Partner or any such officer in connection with any such dealing.
In no event shall any Person dealing with the General Partner or any such
officer or its representatives be obligated to ascertain that the terms of this
Agreement have been complied with or to inquire into the necessity or expedience
of any act or action of the General Partner or any such officer or its
representatives. Each and every certificate, document or other instrument
executed on behalf of the Partnership by the General Partner or its
representatives shall be conclusive evidence in favor of any and every Person
relying thereon or claiming thereunder that (a) at the time of the execution and
delivery of such certificate, document or instrument, this Agreement was in full
force and effect, (b) the Person executing and delivering such certificate,
document or instrument was duly authorized and empowered to do so for and on
behalf of the Partnership and (c) such certificate, document or instrument was
duly executed and delivered in accordance with the terms and provisions of this
Agreement and is binding upon the Partnership.

provided that the books and records so maintained are convertible into clearly
legible written form within a reasonable period of time. The books of the
Partnership shall be maintained, for financial reporting purposes, on an accrual
basis in accordance with U.S. GAAP. The Partnership shall not be required to
keep books maintained on a cash basis and the General Partner shall be permitted
to calculate cash-based measures, including Operating Surplus, by making such
adjustments to its accrual basis books to account for non-cash items and other
adjustments as the General Partner determines to be necessary or appropriate.
Section 8.2    Fiscal Year. The fiscal year of the Partnership shall be a fiscal
year ending December 31.
Section 8.3    Reports.

(a)    Whether or not the Partnership is subject to the requirement to file
reports with the Commission, as soon as practicable, but in no event later than
105 days after the close of each fiscal year of the Partnership (or such shorter
period as required by the Commission), the General Partner shall cause to be
mailed or made available, by any reasonable means (including posting on or
accessible through the Partnership’s or the Commission’s website) to each Record
Holder of a Limited Partner Unit as of a date selected by the General Partner,
an annual report

79

--------------------------------------------------------------------------------

containing financial statements of the Partnership for such fiscal year of the
Partnership, presented in accordance with U.S. GAAP, including a balance sheet
and statements of operations, Partnership equity and cash flows, such statements
to be audited by a firm of independent public accountants selected by the

law, regulation or rule of the Commission or any National Securities Exchange on
which any Limited Partner Units are listed or admitted to trading, or as the
General Partner determines to be necessary or appropriate.
(b)    Whether or not the Partnership is subject to the requirement to file
reports with the Commission, as soon as practicable, but in no event later than
50 days after the close of each Quarter (or such shorter period as required by
the Commission) except the last Quarter of each fiscal year, the General Partner
shall cause to be mailed or made available, by any reasonable means (including
posting on or accessible through the Partnership’s or the Commission’s website)
to each Record Holder of a Limited Partner Unit, as of a date selected by the
General Partner, a report containing unaudited financial statements of the
Partnership and such other information as may be required by applicable law,
regulation or rule of the Commission or any National Securities Exchange on
which any Limited Partner Units are listed or admitted to trading, or as the
General Partner determines to be necessary or appropriate.
ARTICLE IX
TAX MATTERS
Section 9.1    Tax Returns and Information. The Partnership shall timely file
all returns of the Partnership that are required for federal, state and local
income tax purposes on the basis of the accrual method and the taxable period or
year that it is required by law to adopt, from time to time, as determined by
the General Partner. In the event the Partnership is required to use a taxable
period other than a year ending on December 31, the General Partner shall use
reasonable efforts to change the taxable period of the Partnership to a year
ending on December 31. The tax information reasonably required by Record Holders
for federal, state and local income tax reporting purposes with respect to a
taxable period shall be furnished to them within 90 days of the close of the
calendar year in which the Partnership’s taxable period ends. The
classification, realization and recognition of income, gain, losses and
deductions and other items shall be on the accrual method of accounting for
federal income tax purposes.
Section 9.2    Tax Elections.
(a)    The Partnership shall make the election under Section 754 of the Code in
accordance with applicable regulations thereunder, subject to the reservation of
the right to seek to revoke any such election upon the General Partner’s
determination that such revocation is in the best interests of the Limited
Partners. Notwithstanding any other provision herein contained, for the purposes
of computing the adjustments under Section 743(b) of the Code, the General
Partner shall be authorized (but not required) to adopt a convention whereby the
price paid by a transferee of a Limited Partner Interest will be deemed to be
the lowest quoted closing price of the Limited Partner Interests on any National
Securities Exchange on which such Limited Partner Interests are listed or
admitted to trading during the calendar month in which such transfer is deemed
to occur pursuant to Section 6.2(f) without regard to the actual price paid by
such transferee.

80

--------------------------------------------------------------------------------

(b)    Except as otherwise provided herein, the General Partner shall determine
whether the Partnership should make any other elections permitted by the Code.
Section 9.3    Tax Controversies.
(a)        Subject to the provisions hereof, the General Partner (or its
designee) is designated as the “Tax Matters Partner” (as defined in Section
6231(a)(7) of the Code as in effect prior to the enactment of the Bipartisan
Budget Act of 2015), and the “Partnership Representative” (as defined in Section
6223 of the Code following the enactment of the Bipartisan Budget Act of 2015 or
under any applicable state or local law providing for an analogous capacity),
and is authorized and required to represent the Partnership (at the
Partnership’s expense) in connection with all examinations of the Partnership’s
affairs by tax authorities, including resulting administrative and judicial
proceedings, and to expend Partnership funds for professional services and costs
associated therewith. In its capacity as Partnership Representative, the General
Partner shall exercise, in its sole discretion, any and all authority of the
Partnership Representative, including, without limitation, (i) binding the
Partnership and its Partners with respect to tax matters and (ii) determining
whether to make any available election under Section 6226 of the Code or an
analogous election under state or local law, which election permits the
Partnership to pass any partnership adjustment through to the Persons who were
Partners of the Partnership in the year to which the adjustment relates and
irrespective of whether such Persons are Partners of the Partnership at the time
such election is made. Each Partner agrees to cooperate with the General Partner
and to do or refrain from doing any or all things reasonably required by the
General Partner in its capacity as Tax Matters Partner or Partnership
Representative. For Partners that are not tax-exempt entities (as defined in
Section 168(h)(2) of the Code) and subject to the General Partner’s discretion
to seek modifications of an imputed underpayment, this cooperation includes (i)
filing amended federal, state or local tax returns, paying any additional tax
(including interest, penalties and other additions to tax), and providing the
General Partner with an affidavit swearing to those facts (all within the
requisite time periods), and (ii) providing any other information requested by
the General Partner in order to seek modifications of an imputed underpayment.
For Partners that are tax-exempt entities (as defined in Section 168(h)(2) of
the Code) and subject to the General Partner’s discretion to seek modifications
of an imputed underpayment, this cooperation includes providing the General
Partner with information necessary to establish the Partner’s tax-exempt status.
This agreement to cooperate applies irrespective of whether such Persons are
Partners of the Partnership at the time of the requested cooperation.
(b)    Each Partner agrees that notice of or updates regarding tax controversies
shall be deemed conclusively to have been given or made by the General Partner
if the Partnership has either (i) filed the information for which notice is
required with the Commission via its Electronic Data Gathering, Analysis and
Retrieval system and such information is publicly available on such system or
(ii) made the information for which notice is required available on any publicly
available website maintained by the Partnership, whether or not such Partner
remains a Partner in the Partnership at the time such information is made
publicly available. Notwithstanding anything herein to the contrary, nothing in
this provision shall obligate the Partnership Representative to provide notice
to the Partners other than as required by the Code.

81

--------------------------------------------------------------------------------

(c)    The General Partner may amend the provisions of this Agreement as it
determines appropriate to satisfy any requirements, conditions, or guidelines
set forth in any amendment to the provisions of Subchapter C of Chapter 63 of
Subtitle F of the Code, any analogous provisions of the laws of any state or
locality, or the promulgation of regulations or publication of other
administrative guidance thereunder.
Section 9.4    Withholding and Other Tax Payments by the Partnership.
(a)        The General Partner may treat taxes paid by the Partnership on behalf
of all or less than all of the Partners as a distribution of cash to such
Partners, or a general expense of the Partnership, or as indemnifiable payments
made by the Partnership on behalf of the Partners or former Partners (as
provided in Section 9.4(c)), as determined appropriate under the circumstances
by the General Partner.
(b)    Notwithstanding any other provision of this Agreement, the General
Partner is authorized to take any action that may be required to cause the
Partnership and other Group Members to comply with any withholding requirements
established under the Code or any other federal, state or local law including
pursuant to Sections 1441, 1442, 1445 and 1446 of the Code, or established under
any foreign law. To the extent that the Partnership is required or elects to
withhold and pay over to any taxing authority any amount resulting from the
allocation or distribution of income or from a distribution to any Partner
(including by reason of Section 1446 of the Code), the General Partner may treat
the amount withheld as a distribution of cash pursuant to Section 6.3 or
Section 12.4(c) in the amount of such withholding from such Partner.
(c)    If the Partnership pays an imputed underpayment under Section 6225 of the
Code and/or any analogous provision of the laws of any state or locality, the
General Partner may require that some or all of the Partners of the Partnership
in the year to which the underpayment relates indemnify the Partnership for
their allocable share of that underpayment (including interest, penalties and
other additions to tax). This indemnification obligation shall not apply to a
Partner to the extent that (i) the Partnership received a modification of the
imputed underpayment under Section 6225(c)(2) of the Code (or any analogous
provision of state or local law) due to the Partner’s filing of amended tax
returns and payment of any resulting tax (including interest, penalties and
other additions to tax), (ii) the Partner is a tax-exempt entity (as defined in
Section 168(h)(2) of the Code) and either the Partnership received a
modification of the imputed underpayment under Section 6225(c)(3) of the Code
(or any analogous provision of state or local law) because of such Partner’s
status as a tax-exempt entity or the Partnership did not make a good faith
effort to obtain a modification of the imputed underpayment due to such
Partner’s status as a tax-exempt entity, or (iii) the Partnership received a
modification of the imputed underpayment under Section 6225(c)(4)-(6) of the
Code (or any analogous provision of state or local law) as a result of other
information that was either provided by the Partner or otherwise available to
the Partnership with respect to the Partner. This indemnification obligation
imposed on Partners, including former Partners, applies irrespective of whether
such Persons are Partners of the Partnership at the time the Partnership pays
the imputed underpayment.

Limited Partner shall, in exercising the rights of a Limited Partner in respect
of such Limited Partner Units on any matter, and unless the arrangement between
such Persons provides otherwise, take all action as a Limited Partner by virtue
of being the Record Holder of such Limited Partner Units at the direction of the
Person who is the beneficial owner, and the Partnership shall be entitled to
assume such Limited Partner is so acting without further inquiry.

(e)    Any transfer of a Limited Partner Interest shall not entitle the
transferee to share in the profits and losses, to receive distributions, to
receive allocations of income, gain,

83

--------------------------------------------------------------------------------

loss, deduction or credit or any similar item or to any other rights to which
the transferor was entitled until the transferee becomes a Limited Partner

the Partnership as the General Partner, effective immediately prior to the
withdrawal or removal of the predecessor or transferring General Partner,
pursuant to Section 11.1 or 11.2 or the transfer of the General Partner Interest
pursuant to Section 4.6; provided, however, that no such successor shall be
admitted to the Partnership until compliance with the terms of Section 4.6 has
occurred and such successor has executed and delivered such other documents or
instruments as may be required to effect such admission. Any such successor is
hereby authorized to and shall, subject to the terms hereof, carry on the
business of the members of the Partnership Group without dissolution.
Section 10.3    Amendment of Agreement and Certificate of Limited Partnership.
To effect the admission to the Partnership of any Partner, the General Partner
shall take all steps necessary or appropriate under the Delaware Act to amend
the records of the Partnership to reflect such admission and, if necessary, to
prepare as soon as practicable an amendment to this Agreement and, if required
by law, the General Partner shall prepare and file an amendment to the
Certificate of Limited Partnership.

charter without a reinstatement of its charter, under the laws of its state of
incorporation; (B) if the General Partner is a partnership or a limited
liability company, the dissolution and commencement of winding up of the General
Partner; (C) if the General Partner is acting in such capacity by virtue of
being a trustee of a trust, the termination of the trust; (D) if the General
Partner is a natural person, his death or adjudication of incompetency; and
(E) otherwise upon the termination of the General Partner.
If an Event of Withdrawal specified in Section 11.1(a)(iv), (v) or (vi)(A), (B),
(C) or (E) occurs, the withdrawing General Partner shall give notice to the
Limited Partners within 30 days after such occurrence. The Partners hereby agree
that only the Events of Withdrawal described in this Section 11.1 shall result
in the withdrawal of the General Partner from the Partnership.
(b)    Withdrawal of the General Partner from the Partnership upon the
occurrence of an Event of Withdrawal shall not constitute a breach of this
Agreement under the following circumstances: (i) at any time during the period
beginning on the Closing Date and ending at 12:00 midnight, Eastern Time, on
December 31, 2022 the General Partner voluntarily withdraws by giving at least
90 days’ advance notice of its intention to withdraw to the Limited Partners;
provided, that prior to the effective date of such withdrawal, the withdrawal is
approved by Unitholders holding a majority of the Voting Eligible Common Units
(excluding Common Units owned by the General Partner and its Affiliates) and
Series A Preferred Units voting together as a single class and the General
Partner delivers to the Partnership an Opinion of Counsel (“Withdrawal Opinion
of Counsel”) that such withdrawal (following the selection of the successor
General Partner) would not result in the loss of the limited liability under the
Delaware Act of any Limited Partner or cause any Group Member to be treated as
an association taxable as a corporation or otherwise to be taxed as an entity
for federal income tax purposes (to the extent not already so treated or taxed);
(ii) at any time after 12:00 midnight, Eastern Time, on December 31, 2022 the
General Partner voluntarily withdraws by giving at least 90 days’ advance notice
to the Unitholders, such withdrawal to take effect on the date specified in such
notice; (iii) at any time that the General Partner ceases to be the General
Partner pursuant to Section 11.1(a)(ii) or is removed pursuant to Section 11.2;
or (iv) notwithstanding clause (i) of this sentence, at any time that the
General Partner voluntarily withdraws by giving at least 90 days’ advance notice
of its intention to withdraw to the Limited Partners, such withdrawal to take
effect on the date specified in the notice, if at the time such notice is given
one Person and its Affiliates (other than the General Partner and its
Affiliates) own beneficially or of record or control at least 50% of the
outstanding Limited Partner Units. The withdrawal of the General Partner from
the Partnership upon the occurrence of an Event of Withdrawal shall also
constitute the withdrawal of the General Partner as general partner or managing
member, if any, to the extent applicable, of the other Group Members. If the
General Partner gives a notice of withdrawal pursuant to Section 11.1(a)(i), the
holders of a Unit Majority, may, prior to the effective date of such withdrawal,
elect a successor General Partner. The Person so elected as successor General
Partner shall automatically become the successor general partner or managing

85

--------------------------------------------------------------------------------

member, to the extent applicable, of the other Group Members of which the
General Partner is a general partner or a managing member. If, prior to the
effective date of the General Partner’s withdrawal, a successor is not elected
by the Unitholders as provided herein or the Partnership does not receive a
Withdrawal Opinion of Counsel, the Partnership shall be dissolved in accordance
with Section 12.1 unless the business of the Partnership is continued pursuant
to Section 12.2. Any successor General Partner elected in accordance with the
terms of this Section 11.1 shall be subject to the provisions of Section 10.2.
Section 11.2    Removal of the General Partner. The General Partner may be
removed if such removal is approved by the Unitholders holding at least 66 2/3%
of the Voting Eligible Limited Partner Units (including Limited Partner Units
held by the General Partner and its Affiliates) voting as a single class. Any
such action by such holders for removal of the General Partner must also provide
for the election of a successor General Partner by the Unitholders holding a
Unit Majority. Such removal shall be effective immediately following the
admission of a successor General Partner pursuant to Section 10.2. The removal
of the General Partner shall also automatically constitute the removal of the
General Partner as general partner or managing member, to the extent applicable,
of the other Group Members of which the General Partner is a general partner or
a managing member. If a Person is elected as a successor General Partner in
accordance with the terms of this Section 11.2, such Person shall, upon
admission pursuant to Section 10.2, automatically become a successor general
partner or managing member, to the extent applicable, of the other Group Members
of which the General Partner is a general partner or a managing member. The
right of the holders of Voting Eligible Limited Partner Units to remove the
General Partner shall not exist or be exercised unless the Partnership has
received an opinion opining as to the matters covered by a Withdrawal Opinion of
Counsel. Any successor General Partner elected in accordance with the terms of
this Section 11.2 shall be subject to the provisions of Section 10.2.
Section 11.3    Interest of Departing General Partner and Successor General
Partner.
(a)    In the event of (i) withdrawal of the General Partner under circumstances
where such withdrawal does not violate this Agreement or (ii) removal of the
General Partner by the holders of Voting Eligible Limited Partner Units under
circumstances where Cause does not exist, if the successor General Partner is
elected in accordance with the terms of Section 11.1 or Section 11.2, the
Departing General Partner shall have the option, exercisable prior to the
effective date of the withdrawal or removal of such Departing General Partner,
to require its successor to purchase its General Partner Interest and its or its
Affiliates’ general partner interest (or equivalent interest), if any, in the
other Group Members (collectively, the “Combined Interest”) in exchange for an
amount in cash equal to the fair market value of such Combined Interest, such
amount to be determined and payable as of the effective date of its withdrawal
or removal. If the General Partner is removed by the Unitholders under
circumstances where Cause exists or if the General Partner withdraws under
circumstances where such withdrawal violates this Agreement, and if a successor
General Partner is elected in accordance with the terms of Section 11.1 or
Section 11.2 (or if the business of the Partnership is continued pursuant to
Section 12.2 and the successor General Partner is not the former General
Partner), such successor shall have the option, exercisable prior to the
effective date of the withdrawal or removal of such Departing General Partner
(or, in the event the business of the Partnership is continued, prior to

86

--------------------------------------------------------------------------------

the date the business of the Partnership is continued), to purchase the Combined
Interest for such fair market value of such Combined Interest. In either event,
the Departing General Partner shall be entitled to receive all reimbursements
due such Departing General Partner pursuant to Section 7.4, including any
employee-related liabilities (including severance liabilities), incurred in
connection with the termination of any employees employed by the Departing
General Partner or its Affiliates (other than any Group Member) for the benefit
of the Partnership or the other Group Members.

For purposes of this Section 11.3(a), the fair market value of the Combined
Interest shall be determined by agreement between the Departing General Partner
and its successor or, failing agreement within 30 days after the effective date
of such Departing General Partner’s withdrawal or removal, by an independent
investment banking firm or other independent expert selected by the Departing
General Partner and its successor, which, in turn, may rely on other experts,
and the determination of which shall be conclusive as to such matter. If such
parties cannot agree upon one independent investment banking firm or other
independent expert within 45 days after the effective date of such withdrawal or
removal, then the Departing General Partner shall designate an independent
investment banking firm or other independent expert, the Departing General
Partner’s successor shall designate an independent investment banking firm or
other independent expert, and such firms or experts shall mutually select a
third independent investment banking firm or independent expert, which third
independent investment banking firm or other independent expert shall determine
the fair market value of the Combined Interest. In making its determination,
such third independent investment banking firm or other independent expert may
consider the then current trading price of Limited Partner Units on any National
Securities Exchange on which any Limited Partner Units are then listed or
admitted to trading, the value of the Partnership’s assets, the rights and
obligations of the Departing General Partner, the value of the General Partner
Interest and other factors it may deem relevant.
(b)    If the Combined Interest is not purchased in the manner set forth in
Section 11.3(a), the Departing General Partner (or its transferee) shall become
a Limited Partner and its Combined Interest shall be converted into Common Units
pursuant to a valuation made by an investment banking firm or other independent
expert selected pursuant to Section 11.3(a), without reduction in such
Partnership Interest (but subject to proportionate dilution by reason of the
admission of its successor). Any successor General Partner shall indemnify the
Departing General Partner (or its transferee) as to all debts and liabilities of
the Partnership arising on or after the date on which the Departing General
Partner (or its transferee) becomes a Limited Partner. For purposes of this
Agreement, conversion of the Combined Interest of the Departing General Partner
to Common Units will be characterized as if the Departing General Partner (or
its transferee) contributed its Combined Interest to the Partnership in exchange
for the newly issued Common Units.
(c)    [Reserved.]
Section 11.4    [Reserved.]
Section 11.5    Withdrawal of Limited Partners. No Limited Partner shall have
any right to withdraw from the Partnership; provided, however, that when a
transferee of a Limited Partner’s Limited Partner Interest becomes a Record
Holder of the Limited Partner Interest so

87

--------------------------------------------------------------------------------

transferred, such transferring Limited Partner shall cease to be a Limited
Partner with respect to the Limited Partner Interest so transferred.
ARTICLE XII
DISSOLUTION AND LIQUIDATION

Section 12.1    Dissolution. The Partnership shall not be dissolved by the
admission of additional Limited Partners or by the admission of a successor
General Partner in accordance with the terms of this Agreement. Upon the removal
or withdrawal of the General Partner, if a successor General Partner is elected
pursuant to Section 11.1, Section 11.2 or Section 12.2, to the fullest extent
permitted by law, the Partnership shall not be dissolved and such successor
General Partner shall continue the business of the Partnership. The Partnership
shall dissolve, and (subject to Section 12.2) its affairs shall be wound up,
upon:
(a)        an Event of Withdrawal of the General Partner as provided in
Section 11.1(a) (other than Section 11.1(a)(ii)), unless a successor is elected
and a Withdrawal Opinion of Counsel is received as provided in Section 11.1(b)
or 11.2 and such successor is admitted to the Partnership pursuant to
Section 10.2;
(b)    an election to dissolve the Partnership by the General Partner that is
approved by the holders of a Unit Majority;
(c)    the entry of a decree of judicial dissolution of the Partnership pursuant
to the provisions of the Delaware Act; or
(d)    at any time there are no Limited Partners, unless the Partnership is
continued without dissolution in accordance with the Delaware Act.
Section 12.2    Continuation of the Business of the Partnership After
Dissolution. Upon (a) dissolution of the Partnership following an Event of
Withdrawal caused by the withdrawal or removal of the General Partner as
provided in Section 11.1(a)(i) or (iii) and the failure of the Partners to
select a successor to such Departing General Partner pursuant to Section 11.1 or
Section 11.2, then, to the maximum extent permitted by law, within 90 days
thereafter, or (b) dissolution of the Partnership upon an event constituting an
Event of Withdrawal as defined in Section 11.1(a)(iv), (v) or (vi), then, to the
maximum extent permitted by law, within 180 days thereafter, the holders of a
Unit Majority may elect to continue the business of the Partnership on the same
terms and conditions set forth in this Agreement by appointing as a successor
General Partner a Person approved by the holders of a Unit Majority. Unless such
an election is made within the applicable time period as set forth above, the
Partnership shall conduct only activities necessary to wind up its affairs. If
such an election is so made, then:
(i)    the Partnership shall continue without dissolution unless earlier
dissolved in accordance with this Article XII;
(ii)    if the successor General Partner is not the former General Partner, then
the interest of the former General Partner shall be treated in the manner
provided in Section 11.3; and

88

--------------------------------------------------------------------------------

(iii)    the successor General Partner shall be admitted to the Partnership as
General Partner, effective as of the Event of Withdrawal, by agreeing in writing
to be bound by this Agreement;
provided, however, that the right of the holders of a Unit Majority to approve a
successor General Partner and to continue the business of the Partnership shall
not exist and may not be exercised unless the Partnership has received an
Opinion of Counsel that (x) the exercise of the right would not result in the
loss of limited liability of any Limited Partner under the Delaware Act and (y)
neither the Partnership nor any Group Member would be treated as an association
taxable as a corporation or otherwise be taxable as an entity for federal income
tax purposes upon the exercise of such right to continue (to the extent not
already so treated or taxed).
Section 12.3    Liquidator. Upon dissolution of the Partnership, unless the
business of the Partnership is continued pursuant to Section 12.2, the General
Partner shall select one or more Persons to act as Liquidator. The Liquidator
(if other than the General Partner) shall be entitled to receive such
compensation for its services as may be approved by holders of at least a Unit
Majority . The Liquidator (if other than the General Partner) shall agree not to
resign at any time without 15 days’ prior notice and may be removed at any time,
with or without cause, by notice of removal approved by holders of at least a
Unit Majority. Upon dissolution, removal or resignation of the Liquidator, a
successor and substitute Liquidator (who shall have and succeed to all rights,
powers and duties of the original Liquidator) shall within 30 days thereafter be
approved by holders of at least a Unit Majority. The right to approve a
successor or substitute Liquidator in the manner provided herein shall be deemed
to refer also to any such successor or substitute Liquidator approved in the
manner herein provided. Except as expressly provided in this Article XII, the
Liquidator approved in the manner provided herein shall have and may exercise,
without further authorization or consent of any of the parties hereto, all of
the powers conferred upon the General Partner under the terms of this Agreement
(but subject to all of the applicable limitations, contractual and otherwise,
upon the exercise of such powers, other than the limitation on sale set forth in
Section 7.3) necessary or appropriate to carry out the duties and functions of
the Liquidator hereunder for and during the period of time required to complete
the winding up and liquidation of the Partnership as provided for herein.
Section 12.4    Liquidation. The Liquidator shall proceed to dispose of the
assets of the Partnership, discharge its liabilities, and otherwise wind up its
affairs in such manner and over such period as determined by the Liquidator,
subject to Section 17-804 of the Delaware Act and the following:
(a)    The assets may be disposed of by public or private sale or by
distribution in kind to one or more Partners on such terms as the Liquidator and
such Partner or Partners may agree. If any property is distributed in kind, the
Partner receiving the property shall be deemed for purposes of Section 12.4(c)
to have received cash equal to its fair market value; and contemporaneously
therewith, appropriate cash distributions must be made to the other Partners.
The Liquidator may defer liquidation or distribution of the Partnership’s assets
for a reasonable time if it determines that an immediate sale or distribution of
all or some of the Partnership’s assets would be impractical or would cause
undue loss to the Partners. The Liquidator may distribute the Partnership’s
assets, in whole or in part, in kind if it determines that a sale would be
impractical or would cause undue loss to the Partners.

89

--------------------------------------------------------------------------------

(b)    Liabilities of the Partnership include amounts owed to the Liquidator as
compensation for serving in such capacity (subject to the terms of Section 12.3)
and amounts to Partners otherwise than in respect of their distribution rights
under Article VI. With respect to any liability that is contingent, conditional
or unmatured or is otherwise not yet due and payable, the Liquidator shall
either settle such claim for such amount as it thinks appropriate or establish a
reserve of cash or other assets to provide for its payment. When paid, any
unused portion of the reserve shall be distributed as additional liquidation
proceeds.
(c)    All property and all cash in excess of that required to satisfy
liabilities as provided in Section 12.4(b) shall be distributed to the Partners
in accordance with, and to the extent of, the positive balances in their
respective Capital Accounts, as determined after taking into account all Capital
Account adjustments (including, without limitation, the allocation provided for
under Section 6.1(d)(xi)(C), which allocates items of gross income, gain, loss
and deduction among the Partners to the maximum extent possible to provide a
preference in liquidation to the Capital Account of the Series A Preferred Units
over the Capital Accounts of Series A Junior Interests, but excluding
adjustments made by reason of distributions pursuant to this Section 12.4(c))
for the taxable period of the Partnership during which the liquidation of the
Partnership occurs (with such date of occurrence being determined pursuant to
Treasury Regulation Section 1.704-1(b)(2)(ii)(g)), and such distribution shall
be made by the end of such taxable period (or, if later, within 90 days after
said date of such occurrence); provided that any cash or cash equivalents
available for distribution under this Section 12.4(c) shall be distributed with
respect to the Series A Preferred Units and Series A Senior Securities (up to
the positive balances in the associated Capital Accounts) prior to any
distribution of cash or cash equivalents with respect to the Series A Junior
Securities.
Section 12.5    Cancellation of Certificate of Limited Partnership. Upon the
completion of the distribution of Partnership cash and property as provided in
Section 12.4 in connection with the liquidation of the Partnership, the
Certificate of Limited Partnership and all qualifications of the Partnership as
a foreign limited partnership in jurisdictions other than the State of Delaware
shall be canceled and such other actions as may be necessary to terminate the
Partnership shall be taken.
Section 12.6    Return of Contributions. The General Partner shall not be
personally liable for, and shall have no obligation to contribute or loan any
monies or property to the Partnership to enable it to effectuate, the return of
the Capital Contributions of the Limited Partners or Unitholders, or any portion
thereof, it being expressly understood that any such return shall be made solely
from Partnership assets.
Section 12.7    Waiver of Partition. To the maximum extent permitted by law,
each Partner hereby waives any right to partition of the Partnership property.
Section 12.8    Capital Account Restoration. No Limited Partner shall have any
obligation to restore any negative balance in its Capital Account upon
liquidation of the Partnership. The General Partner shall be obligated to
restore any negative balance in its Capital Account upon liquidation of its
interest in the Partnership by the end of the taxable year of the Partnership
during which such liquidation occurs, or, if later, within 90 days after the
date of such liquidation.

is required under this Agreement. Each proposed amendment that requires the
approval of the holders of a specified percentage of Voting Eligible Limited
Partner Units or class of Limited Partners shall be set forth in a writing that
contains the text of the proposed amendment. If such an amendment is proposed,
the General Partner shall seek the written approval of the requisite percentage
of Voting Eligible Limited Partner Units or class of Limited Partners or call a

Holders as

--------------------------------------------------------------------------------

required by this Section 13.2 if it has posted or made accessible such amendment
through the Partnership’s or the Commission’s website.
Section 13.3    Amendment Requirements.
(a)        Notwithstanding the provisions of Section 13.1 and Section 13.2, no
provision of this Agreement that establishes a percentage of Voting Eligible
Limited Partner Units or class of Limited Partners required to take any action
shall be amended, altered, changed, repealed or rescinded in any respect that
would have the effect of (i) in the case of any provision of this Agreement
other than Section 11.2 or Section 13.4, reducing such percentage or changing
the required vote of such class or (ii) in the case of Section 11.2 or
Section 13.4, increasing such percentages or changing the required vote of such
class, unless such amendment is approved by the written consent or the
affirmative vote of holders of Voting Eligible Limited Partner Units whose
aggregate Voting Eligible Limited Partner Units constitute (w) in the case of a
change of the required vote of such class as described in subclause (a)(i) or
(a)(ii), not less than 66.7% of the class to be changed, (x) in the case of a
reduction as described in subclause (a)(i) hereof, not less than the voting
requirement sought to be reduced, (y) in the case of an increase in the
percentage in Section 11.2, not less than 90% of the Voting Eligible Limited
Partner Units, or (z) in the case of an increase in the percentage in
Section 13.4, not less than a majority of the Voting Eligible Limited Partner
Units.
(b)    Notwithstanding the provisions of Section 13.1 and Section 13.2, no
amendment to this Agreement may (i) enlarge the obligations of any Limited
Partner without its consent, unless such shall be deemed to have occurred as a
result of an amendment approved pursuant to Section 13.3(c) or (ii) enlarge the
obligations of, restrict in any way any action by or rights of, or reduce in any
way the amounts distributable, reimbursable or otherwise payable to, the General
Partner or any of its Affiliates without its consent, which consent may be given
or withheld at its option.
(c)    Except as provided in Section 14.3, and without limitation of the General
Partner’s authority to adopt amendments to this Agreement without the approval
of any Partners as contemplated in Section 13.1, any amendment that would have a
material adverse effect on the rights or preferences of any class of Partnership
Interests in relation to other classes of Partnership Interests must be approved
by the holders of not less than a majority of the Voting Eligible Partnership
Interests of the class affected.
(d)    Notwithstanding any other provision of this Agreement, except for
amendments pursuant to Section 13.1 and except as otherwise provided by
Section 14.3(f), no amendments shall become effective without the approval of
the holders of at least 90% of the Voting Eligible Limited Partner Units voting
as a single class unless the Partnership obtains an Opinion of Counsel to the
effect that such amendment will not affect the limited liability of any Limited
Partner under applicable partnership law of the state under whose laws the
Partnership is organized.
(e)    Except as provided in Section 13.1, this Section 13.3 shall only be
amended with the approval of the holders of at least 90% of the Voting Eligible

--------------------------------------------------------------------------------

Section 13.4    Special Meetings. All acts of Limited Partners to be taken
pursuant to this Agreement shall be taken in the manner provided in this
Article XIII. Special meetings of the Limited Partners may be called by the
General Partner or by Limited Partners owning 20% or more of the Voting Eligible
Limited Partner Units of the class or classes for which a meeting is proposed.
Limited Partners shall call a special meeting by delivering to the General
Partner one or more requests in writing stating that the signing Limited
Partners wish to call a special meeting and indicating the specific purposes for
which the special meeting is to be called and the class or classes of Limited
Partner Units for which the meeting is proposed. No business may be brought by
any Limited Partner before such special meeting except the business listed in
the related request. Within 60 days after receipt of such a call from Limited
Partners or within such greater time as may be reasonably necessary for the
Partnership to comply with any statutes, rules, regulations, listing agreements
or similar requirements governing the holding of a meeting or the solicitation
of proxies for use at such a meeting, the General Partner shall send or cause to
be sent a notice of the meeting to the Limited Partners. A meeting shall be held
at a time and place determined by the General Partner on a date not less than 10
days nor more than 60 days after the time notice of the meeting is given as
provided in Section 16.1. Limited Partners shall not be permitted to vote on
matters that would cause the Limited Partners to be deemed to be taking part in
the management and control of the business and affairs of the Partnership so as
to jeopardize the Limited Partners’ limited liability under the Delaware Act or
the law of any other state in which the Partnership is qualified to do business.
If any such vote were to take place, to the fullest extent permitted by law, it
shall be deemed null and void to the extent necessary so as not to jeopardize
the Limited Partners’ limited liability under the Delaware Act or the law of any
other state in which the Partnership is qualified to do business.
Section 13.5    Notice of a Meeting. Notice of a meeting called pursuant to
Section 13.4 shall be given to the Record Holders of the class or classes of
Limited Partner Units for which a meeting is proposed in writing by mail or
other means of written communication in accordance with Section 16.1.
Section 13.6    Record Date. For purposes of determining the Limited Partners
who are Record Holders of the class or classes of Limited Partner Interests
entitled to notice of or to vote at a meeting of the Limited Partners or to give
approvals without a meeting as provided in Section 13.11, the General Partner
shall set a Record Date, which shall not be less than 10 nor more than 60 days
before (a) the date of the meeting (unless such requirement conflicts with any
rule, regulation, guideline or requirement of any National Securities Exchange
on which any Limited Partner Units are listed or admitted to trading or U.S.
federal securities laws, in which case the rule, regulation, guideline or
requirement of such National Securities Exchange or U.S. federal securities laws
shall govern) or (b) in the event that approvals are sought without a meeting,
the date by which such Limited Partners are requested in writing by the General
Partner to give such approvals.

Section 13.7    Postponement and Adjournment. Prior to the date upon which any
meeting of Limited Partners is to be held, the General Partner may postpone such
meeting one or more times for any reason by giving notice to each Limited
Partner entitled to vote at the meeting so postponed of the place, date and hour
at which such meeting would be held. Such notice shall be given not fewer than
two days before the date of such meeting and otherwise in accordance with this
Article XIII. When a meeting is postponed, a new Record Date need not be

94

--------------------------------------------------------------------------------

fixed unless such postponement shall be for more than 45 days. Any meeting of
Limited Partners may be adjourned by the General Partner one or more times for
any reason, including the failure of a quorum to be present at the meeting with
respect to any proposal or the failure of any proposal to receive sufficient
votes for approval. No Limited Partner vote shall be required for any
adjournment. A meeting of Limited Partners may be adjourned by the General
Partner as to one or more proposals regardless of whether action has been taken
on other matters. When a meeting is adjourned to another time or place, notice
need not be given of the adjourned meeting and a new Record Date need not be
fixed, if the time and place thereof are announced at the meeting at which the
adjournment is taken, unless such adjournment shall be for more than 45 days. At
the adjourned meeting, the Partnership may transact any business which might
have been transacted at the original meeting. If the adjournment is for more
than 45 days or if a new Record Date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be given in accordance with this
Article XIII.
Section 13.8    Waiver of Notice; Approval of Meeting. The transactions of any
meeting of Limited Partners, however called and noticed, and whenever held,
shall be as valid as if it had occurred at a meeting duly held after regular
call and notice, if a quorum is present either in person or by proxy. Attendance
of a Limited Partner at a meeting shall constitute a waiver of notice of the
meeting, except when the Limited Partner attends the meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened; and except that
attendance at a meeting is not a waiver of any right to disapprove of any
matters submitted for consideration or to object to the failure to submit for
consideration any matters required to be included in the notice of the meeting,
but not so included, if such objection is expressly made at the beginning of the
meeting.
Section 13.9    Quorum and Voting. The presence, in person or by proxy, of
holders of a majority of the Voting Eligible Limited Partner Units of the class
or classes for which a meeting has been called (including Voting Eligible
Limited Partner Units deemed owned by the General Partner) shall constitute a
quorum at a meeting of Limited Partners of such class or classes unless any such
action by the Limited Partners requires approval by holders of a greater
percentage of such Limited Partner Units, in which case the quorum shall be such
greater percentage. At any meeting of the Limited Partners duly called and held
in accordance with this Agreement at which a quorum is present, the act of
Limited Partners holding Voting Eligible Limited Partner Units that in the
aggregate represent a majority of the Voting Eligible Limited Partner Units
entitled to vote at such meeting shall be deemed to constitute the act of all
Limited Partners, unless a different percentage or class vote is required with
respect to such action under the provisions of this Agreement, in which case the
act of the Limited Partners holding Voting Eligible Limited Partner Units that
in the aggregate represent at least such different percentage, or the act of the
Limited Partners holding the requisite percentage of the necessary class, shall
be required. The Limited Partners present at a duly called or held meeting at
which a quorum is present may continue to transact business until adjournment,
notwithstanding the exit of enough Limited Partners to leave less than a quorum,
if any action taken (other than adjournment) is approved by the required
percentage of Voting Eligible Limited Partner Units or class of Limited Partners
specified in this Agreement.
Section 13.10    Conduct of a Meeting. The General Partner shall have full power
and authority concerning the manner of conducting any meeting of the Limited
Partners or

95

--------------------------------------------------------------------------------

solicitation of approvals in writing, including the determination of Persons
entitled to vote, the existence of a quorum, the satisfaction of the
requirements of Section 13.4, the conduct of voting, the validity and effect of
any proxies and the determination of any controversies, votes or challenges
arising in connection with or during the meeting or voting. The General Partner
shall designate a Person to serve as chairman of any meeting and shall further
designate a Person to take the minutes of any meeting. All minutes shall be kept
with the records of the Partnership maintained by the General Partner. The
General Partner may make such other regulations consistent with applicable law
and this Agreement as it may deem advisable concerning the conduct of any
meeting of the Limited Partners or solicitation of approvals in writing,
including regulations in regard to the appointment of proxies, the appointment
and duties of inspectors of votes and approvals, the submission and examination
of proxies and other evidence of the right to vote, and the submission and
revocation of approvals in writing.
Section 13.11    Action Without a Meeting. If authorized by the General Partner,
any action that may be taken at a meeting of the Limited Partners may be taken
without a meeting if an approval in writing setting forth the action so taken is
signed by Limited Partners owning not less than the minimum percentage of the
Voting Eligible Limited Partner Units or of any class of Limited Partners that
would be necessary to authorize or take such action at a meeting at which all
the Limited Partners were present and voted (unless such provision conflicts
with any rule, regulation, guideline or requirement of any National Securities
Exchange on which any Limited Partner Units are listed or admitted to trading,
in which case the rule, regulation, guideline or requirement of such National
Securities Exchange shall govern). Prompt notice of the taking of action without
a meeting shall be given to the Limited Partners who have not approved in
writing. The General Partner may specify that any written ballot submitted to
Limited Partners for the purpose of taking any action without a meeting shall be
returned to the Partnership within the time period, which shall be not less than
20 days, specified by the General Partner. If a ballot returned to the
Partnership does not vote all of the Voting Eligible Limited Partner Units held
by such Limited Partners, the Partnership shall be deemed to have failed to
receive a ballot for the Voting Eligible Limited Partner Units that were not
voted. If approval of the taking of any permitted action by the Limited Partners
is solicited by any Person other than by or on behalf of the General Partner,
the written approvals shall have no force and effect unless and until (a)
approvals sufficient to take the action proposed are deposited with the
Partnership in care of the General Partner, (b) approvals sufficient to take the
action proposed are dated as of a date not more than 90 days prior to the date
sufficient approvals are first deposited with the Partnership and (c) an Opinion
of Counsel is delivered to the General Partner to the effect that the exercise
of such right and the action proposed to be taken with respect to any particular
matter (i) will not cause the Limited Partners to be deemed to be taking part in
the management and control of the business and affairs of the Partnership so as
to jeopardize the Limited Partners’ limited liability, and (ii) is otherwise
permissible under the state statutes then governing the rights, duties and
liabilities of the Partnership and the Partners.
Section 13.12    Right to Vote and Related Matters.
(a)Only those Record Holders of the Voting Eligible Limited Partner Units on the
Record Date set pursuant to Section 13.6 (and also subject to the limitations
contained in the definition of “Voting Eligible”) shall be entitled to notice
of, and to vote at, a meeting of Limited Partners or to act with respect to
matters as to which the holders of the Voting Eligible

96

--------------------------------------------------------------------------------

Limited Partner Units have the right to vote or to act. All references in this
Agreement to votes of, or other acts that may be taken by, the Voting Eligible
Limited Partner Units shall be deemed to be references to the votes or acts of
the Record Holders of such Voting Eligible Limited Partner Units.

(b)    With respect to Limited Partner Units that are held for a Person’s
account by another Person that is the Record Holder (such as a broker, dealer,
bank, trust company or clearing corporation, or an agent of any of the
foregoing), such Record Holder shall, in exercising the voting rights in respect
of such Limited Partner Units on any matter, and unless the arrangement between
such Persons provides otherwise, vote such Limited Partner Units in favor of,
and at the direction of, the Person who is the beneficial owner, and the
Partnership shall be entitled to assume such Record Holder is so acting without
further inquiry. The provisions of this Section 13.12(b) (as well as all other
provisions of this Agreement) are subject to the provisions of Section 4.3.

Conversion, as the case may be, shall direct that the Merger Agreement or the
Plan of Conversion, as applicable, be submitted to a vote of Limited Partners,
whether at a special meeting or by written consent, in either case in accordance
with the requirements of Article XIII. A copy or a summary of the Merger

Agreement or Plan of Conversion, as the case may be, shall be approved upon
receiving the affirmative vote or consent of the holders of a Unit Majority

greater percentage vote or consent shall be required for approval of the Merger
Agreement or the Plan of Conversion, as the case may be.

--------------------------------------------------------------------------------

(d)    Notwithstanding anything else contained in this Article XIV or in this
Agreement, the General Partner is permitted, without Limited Partner approval,
to convert the Partnership or any Group Member into a new limited liability
entity, to merge the Partnership or any Group Member into, or convey all of the
Partnership’s assets to, another limited liability entity that shall be newly
formed and shall have no assets, liabilities or operations at the time of such
conversion, merger or conveyance other than those it receives from the
Partnership or other Group Member if (i) the General Partner has received an
Opinion of Counsel that the conversion, merger or conveyance, as the case may
be, would not result in the loss of limited liability under the laws of the
jurisdiction governing the other limited liability entity (if that jurisdiction
is not Delaware) of any Limited Partner as compared to its limited liability
under the Delaware Act or cause the Partnership to be treated as an association
taxable as a corporation or otherwise to be taxed as an entity for federal
income tax purposes (to the extent not previously treated as such), (ii) the
sole purpose of such conversion, merger, or conveyance is to effect a mere
change in the legal form of the Partnership into another limited liability
entity and (iii) the General Partner determines that the governing instruments
of the new entity provide the Limited Partners and the General Partner with
substantially the same rights and obligations as are herein contained.
(e)    Additionally, notwithstanding anything else contained in this Agreement,
but subject to Section 5.14(b)(vii), the General Partner is permitted, without
Limited Partner approval, to merge or consolidate the Partnership with or into
another limited liability entity if (i) the General Partner has received an
Opinion of Counsel that the merger or consolidation, as the case may be, would
not result in the loss of the limited liability of any Limited Partner under the
laws of the jurisdiction governing the other limited liability entity (if that
jurisdiction is not Delaware) as compared to its limited liability under the
Delaware Act or cause the Partnership to be treated as an association taxable as
a corporation or otherwise to be taxed as an entity for federal income tax
purposes (to the extent not previously treated as such), (ii) the merger or
consolidation would not result in an amendment to this Agreement, other than any
amendments that could be adopted pursuant to Section 13.1, (iii) the Partnership
is the Surviving Business Entity in such merger or consolidation, (iv) each
Limited Partner Unit outstanding immediately prior to the effective date of the
merger or consolidation is to be an identical Limited Partner Unit of the
Partnership after the effective date of the merger or consolidation, and (v) the
number of Partnership Interests to be issued by the Partnership in such merger
or consolidation does not exceed 20% of the Partnership Interests outstanding
immediately prior to the effective date of such merger or consolidation.
(f)    Pursuant to Section 17-211(g) of the Delaware Act, an agreement of merger
or consolidation approved in accordance with this Article XIV may (i) effect any
amendment to this Agreement or (ii) effect the adoption of a new partnership
agreement for the Partnership if it is the Surviving Business Entity. Any such
amendment or adoption made pursuant to this Section 14.3 shall be effective at
the effective time or date of the merger or consolidation.
Section 14.4    Certificate of Merger or Certificate of Conversion. Upon the
required approval by the General Partner and the Unitholders of a Merger
Agreement or the Plan of Conversion, as the case may be, a certificate of merger
or certificate of conversion or other filing, as applicable, shall be executed
and filed with the Secretary of State of the State of

100

Delaware or the appropriate filing office of any other jurisdiction, as
applicable, in conformity with the requirements of the Delaware Act or other
applicable law.

that has merged or consolidated, and all property, real, personal and mixed, and
all debts due to any of those business entities and all other things and causes
of action belonging to each of those business entities, shall be vested in the
Surviving Business Entity and after the merger or consolidation shall be the
property of the Surviving Business Entity to the extent they were of each
constituent business entity;

those constituent business entities shall not revert and is not in any way
impaired because of the merger or consolidation;

the same extent as if the debts, liabilities and duties had been incurred or
contracted by it.

(i)    the Partnership shall continue to exist, without interruption, but in the
organizational form of the converted entity rather than in its prior
organizational form;
(ii)    all rights, title, and interests to all real estate and other property
owned by the Partnership shall continue to be owned by the converted entity in
its new organizational form without reversion or impairment, without further act
or deed, and without any transfer or assignment having occurred, but subject to
any existing liens or other encumbrances thereon;
(iii)    all liabilities and obligations of the Partnership shall continue to be
liabilities and obligations of the converted entity in its new organizational
form without impairment or diminution by reason of the conversion;
(iv)    all rights of creditors or other parties with respect to or against the

be converted into partnership interests, shares, evidences of ownership, or
other securities in the converted entity as provided in the plan of conversion
shall be so converted, and Partners shall be entitled only to the rights
provided in the Plan of Conversion.

price (determined in accordance with Section 15.1(a)) for Limited Partner
Interests therefor, without interest, upon surrender to the Transfer Agent or
exchange agent of the Certificates representing such Limited Partner Interests,
in the case of Limited Partner Interests evidenced by Certificates, or
instructions agreeing to such redemption, and such Limited Partner Interests
shall thereupon be deemed to be transferred to the General Partner, its
Affiliate or the Partnership, as the case may be, on the Partnership Register,

delivered or made available via such mode of delivery. An affidavit or
certificate of making of any notice, payment or report in accordance with the

the Partnership Register is returned by the United States Postal Service marked
to indicate that the United States Postal Service is unable to deliver it, such
notice, payment or report and any subsequent notices, payments and reports shall
be deemed to have been duly given or made without further mailing (until such
time as such Record Holder or another Person notifies the Transfer Agent or the

among the parties hereto pertaining to the subject matter hereof and supersedes
all prior agreements and understandings pertaining thereto.

Section 16.5    Creditors. None of the provisions of this Agreement shall be for
the benefit of, or shall be enforceable by, any creditor of the Partnership.

Section 16.6    Waiver. No failure by any party to insist upon the strict
performance of any covenant, duty, agreement or condition of this Agreement or
to exercise any right or remedy consequent upon a breach thereof shall
constitute waiver of any such breach of any other covenant, duty, agreement or
condition.

Indemnitee shall be entitled to assert rights and remedies hereunder as a
third-party beneficiary hereto with respect to those provisions of this

all of which together shall constitute an agreement binding on all the parties
hereto, notwithstanding that all such parties are not signatories to the

Agreement immediately upon affixing its signature hereto or, in the case of a
Person acquiring a Limited Partner Interest, pursuant to Section 10.1(b) without
execution hereof.
