ARTICLE II.
EQUITY CONTRIBUTIONS

Section 2.1. Equity Contributions.

(a)  Equity Contributions. Each Contributor hereby irrevocably agrees to make
one or more equity contributions to the Company in accordance with this
Agreement (each an “Equity Contribution”) in an aggregate amount equal to its
Proportionate Contingent Equity Undertaking,

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

subject to and in accordance with the mechanics set forth in Section 2.2, but in
no event, for any Contributor to exceed such Contributor’s Contributor Maximum
Amount.

(b)  Maximum Equity Contributions. Notwithstanding anything to the contrary set
forth in Section 2.1(a) (or in any other Section hereof or other Indenture
Document), in no event shall any Contributor be obligated to make any Equity
Contribution (or aggregate Equity Contributions) that exceeds such Contributor’s
Contributor Maximum Amount.

(c)  No Limitation on Voluntary Equity Contributions. Nothing herein shall be
construed to prohibit or otherwise limit any Contributor or any of its
Affiliates from making or causing to be made voluntary equity contributions to
the Company or the Pipeline Owners at the time and in the amount elected by such
Contributor in its sole discretion or from making or causing to be made equity
contributions to the Company or the Pipeline Owners pursuant to their applicable
constituent documents.

Section 2.2. Contribution Mechanics

(a)  Remediation Contribution Notices. Solely upon or after the occurrence of a
Temporary Trigger Event that occurs prior to a (i) Permitting Trigger Event,
(ii) an event described in clause (ii) of the definition of “Permanent Trigger
Event” and (iii) the Required Contribution Termination Date, the Company shall
deliver a Remediation Contribution Notice to each Contributor, in respect of all
principal and accrued and unpaid interest (without giving effect to any default
rate or make whole or similar payment, if applicable) on any Series of Notes
upon a Series Trigger Event or upon a Remediation Period Acceleration in respect
of such Series of Notes that become due and payable during the Remediation
Period, in each case, to the extent the Company has or is projected to have
insufficient funds to pay such amounts. Upon delivery of the Remediation
Contribution Notice, the Company shall designate an account of the Company for
deposit of such Equity Contribution (the “Contribution Account”). For the
avoidance of doubt, the aggregate amount specified for payment in each
Remediation Contribution Notice shall constitute the Required Equity
Contribution in respect thereof.

(b) Permanent Trigger Event Contribution Notice. Solely upon or after the
occurrence of a Permanent Trigger Event that occurs prior to the Required
Contribution Termination Date, the Company shall (or the Trustee may, pursuant
to Section 2.2(c)) deliver a written notice (the “Contribution Notice”) to each
Contributor, with a copy to the Trustee, setting forth (i) the Permanent Trigger
Event to which such Contribution Notice applies, (ii) the requested date upon
which each Required Equity Contribution shall be due and owing (the
“Contribution Date”) (which shall be no sooner than ten (10) Business Days
following the date such Contribution Notice is delivered), (iii) the amount of
each Required Equity Contribution (which shall not exceed such Contributor’s
Contributor Maximum Amount), and (iv) the Contribution Account.

(c)  Submission of Notices. If the Company shall not have delivered a
Remediation Contribution Notice under Section 2.2(a) or a Contribution Notice
under Section 2.2(b) in respect of any Required Equity Contribution to the
Trustee and each Contributor on or prior to the third Business Day following the
occurrence of such Temporary Trigger Event or Permanent Trigger Event, the
Trustee shall be permitted (but shall not be required) to deliver such
Remediation Contribution Notice or Contribution Notice on behalf of the Company
to each Contributor relating to a Temporary Trigger Event or Permanent Trigger
Event, as applicable, of which it has

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

received written notice from the Company or any Contributor. If the Remediation
Contribution Notice or Contribution Notice is delivered by the Trustee, it will
contain only such information required to be in such notice as provided by the
Company or a Contributor in the written notice to the Trustee. The Trustee may
conclusively rely upon the information given to it by the Company or a
Contributor.

(d)  Cash Funding. Each Contributor shall, on or prior to the applicable
Remediation Contribution Date or Contribution Date, make each Required Equity
Contribution by depositing an amount equal to such Contributor’s Required Equity
Undertaking (but not exceeding such Contributor’s Contributor Maximum Amount),
in each case as specified in the applicable Contribution Notice or Remediation
Contribution Notice (in the case of any dispute as to the amount of any Required
Equity Contribution, as resolved in good faith by the applicable Parties), into
the Contribution Account specified in such Contribution Notice or Remediation
Contribution Notice, no later than 1:00 p.m. (New York City time) on the
applicable Remediation Contribution Date or Contribution Date.

Section 4.1  Waiver of Defenses. Each Contributor hereby unconditionally and
irrevocably waives and relinquishes, to the maximum extent permitted by
applicable Applicable Law, all rights or remedies accorded by applicable
Applicable Law to sureties or guarantors (other than the defense of payment of
the applicable amounts and the defense that the Contributor is not obligated to
perform or has fully performed the matter in question) and agrees not to assert
or take advantage of any such right or remedies, including:

(a)  any right to require any Indenture Party to proceed against the Company or
any other Person or to proceed against or exhaust any security held by any
Indenture Party at any time or to pursue any other remedy in any Indenture
Party’s power before proceeding against such Contributor to enforce the
provisions of this Agreement;

(b)  any defense that may arise by reason of the incapacity, lack of power or
authority, death, dissolution, merger, termination or disability of the Company,
either Pipeline Owner or any other Person or the failure of any Indenture Party
to file or enforce a claim against the estate (in administration, bankruptcy or
any other proceeding) of the Company, either Pipeline Owner or any other Person;

(c)  demand, presentment, protest and notice of any kind (other than any notices
expressly required to be delivered to such Contributor hereunder), creation or
incurring of any new or additional indebtedness or obligation or of any action
or non‑action on the part of the Company, either Pipeline Owner or any Indenture
Party, any endorser or creditor of the foregoing or on the part of any other
Person under the Indenture Documents;

(d)  any defense based upon an election of remedies by the Indenture Parties,
including an election to proceed by non‑judicial rather than judicial
foreclosure, which

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

destroys or otherwise impairs the subrogation rights of such Contributor, the
right of such Contributor to proceed against the Company, either Pipeline Owner
or another Person for reimbursement, or both;

(e)  any defense based on any offset against any amounts which may be owed by
any Person to such Contributor, the Company or either Pipeline Owner or for any
reason whatsoever;

(f)  any defense based upon any Applicable Law which provides that the
obligation of a surety must be neither larger in amount nor in other respects
more burdensome than that of the principal;

(g)  any defense based on any failure to act, delay or omission whatsoever on
the part of the Company, either Pipeline Owner or such Contributor or the
failure by the Company, either Pipeline Owner or such Contributor to do any act
or thing or to observe or perform any covenant, condition or agreement to be
observed or performed by it under the Indenture Documents;

(h)  any defense, setoff or counterclaim which may at any time be available to
or asserted by the Company, either Pipeline Owner or such Contributor against
any Indenture Party or any other Person under the Indenture Documents based on
or related to the bankruptcy or insolvency of the Company or either Pipeline
Owner;

(i)  any duty on the part of any Indenture Party to disclose to such Contributor
any facts such Indenture Party may now or hereafter know about the Company or
either Pipeline Owner, regardless of whether such Indenture Party has reason to
believe that any such facts materially increase the risk beyond that which such
Contributor intends to assume, or have reason to believe that such facts are
unknown to such Contributor, or have a reasonable opportunity to communicate
such facts to such Contributor (such Contributor acknowledging that it is fully
responsible for being and keeping informed of the financial condition of the
Company and the Pipeline Owners);

(j)  any defense based on any change in the time, manner or place of any payment
under, or in any other term of, the Indenture Documents or any other amendment,
renewal, extension, acceleration, compromise or waiver of or any consent or
departure from the terms of the Indenture Documents (other than this Agreement);

(k)  any defense based upon any borrowing or grant of a security interest under
Section 364 of the Bankruptcy Code; and

(l)  any other circumstance (including any statute of limitations) or any
existence of or reliance on any representation by any Indenture Party that might
otherwise constitute a defense available to, or discharge of, any guarantor or
surety (other than setoff against such Contributor or, subject to Section 4.4,
the defense of payment of the applicable amounts).

Section 4.2.  Obligations Unconditional. All rights of the Indenture Parties and
all obligations of each Contributor hereunder shall be absolute and
unconditional irrespective of:

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

(a)  any lack of validity, legality or enforceability of any Indenture Document
(other than this Agreement);

of, all or any portion of the Note Obligations, or any other extension or
renewal of any obligation of the Company, either Pipeline Owner, any Contributor
or otherwise;

(d)  any reduction, limitation, impairment or termination of any of the Note
Obligations for any reason other than the full payment in cash thereof or the
occurrence of the earlier of the date of discharge of the Note Obligations or
the Required Contribution Termination Date, including any claim of waiver,
release, surrender, alteration or compromise;

(e)  any amendment to, rescission, waiver or other modification of, or any
consent to departure from, any term of any Indenture Document unless entered
into and approved in accordance therewith;

(f)  any addition, exchange, release, surrender or non‑perfection of any
collateral, or any amendment to or waiver or release or addition of, or consent
to departure from, any other security interest held by any Indenture Party; or

(g)  any other circumstance which might otherwise constitute a defense available
to, or a legal or equitable discharge of, the Company, either Pipeline Owner,
any Contributor or any surety or guarantor (other than the defense of payment of
the applicable amounts and the defense that the Contributor is not obligated to
perform or has fully performed the matter in question).

Section 4.3. Subrogation. Prior to and until the Termination Date, each
Contributor waives any claim, right or remedy which it may now have or hereafter
acquire against the Company that arises hereunder and/or from the performance by
such Contributor of its obligations hereunder, whether or not such claim, right
or remedy arises in equity, under contract, by statute, under common law or
otherwise. Any amount paid by the Company to any Contributor in violation of the
immediately preceding sentence prior to the Termination Date shall be held in
trust for the benefit of the Trustee (on behalf of the Indenture Parties) and
shall promptly thereafter be paid to the Trustee for application in accordance
with the Indenture Documents.

Section 4.4  Reinstatement.  This Agreement and the obligations of each
Contributor (other than under Section 6.1) and the Company hereunder shall
automatically be reinstated if and to the extent that for any reason any payment
made by or on behalf of any Contributor in respect of any portion of such
Contributor’s Contingent Equity Undertaking pursuant to this Agreement is
rescinded by such Contributor or otherwise restored to (and accepted by) such
Contributor or the Company, whether as a result of any Bankruptcy Event with
respect to the Company, either Pipeline Owner or any other Person, in each case
as if such payment had not

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

been made, provided that such Contributor is repaid any Equity Contribution
provided by it (or its Affiliates) (such repayment, a “Reimbursed Equity
Contribution”); provided, however, that (x) the circumstances described in
clause (b) or (c) of Section 7.13 have not occurred, and (y) any such reinstated
obligations shall be subject to the conditions to the making of an Equity
Contribution that are set forth in Article II.

applicable to or binding on such Contributor or any of its properties or (c) any
applicable order of any court or any rule, regulation or order of any
Governmental Authority, except, in the case of clause (b) or (c) above, where
such violation, creation or imposition would not reasonably be expected to have
a Material Adverse Effect.

Section 5.3. Enforceability.  This Agreement has been duly executed and
delivered by such Contributor and, assuming due authorization, execution and
delivery by each other party hereto, this Agreement constitutes a legal, valid
and binding obligation of such Contributor enforceable against such Contributor
in accordance with its terms, subject to (a) the effects of bankruptcy,
insolvency, moratorium, reorganization, fraudulent conveyance or other similar
laws affecting creditors’ rights generally, (b) general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law) and (c) implied covenants of good faith and fair dealing.

Section 5.4.  No Litigation.   There are no actions, suits, investigations or
proceedings by or before any arbitrator or Governmental Authority pending
against or, to the knowledge of any Contributor, threatened against or affecting
the Contributor that, if adversely determined to or against the Contributor,
would reasonably be expected to have a Material Adverse Effect.

Section 5.5.  Equity Interests. Each Contributor indirectly owns its
Proportionate Interest of the outstanding equity interests in each Pipeline
Owner.

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

Section 5.6.  Compliance with Law. Each Contributor is in compliance with all
applicable Applicable Law, other than any non-compliance that could not
reasonably be expected to have a Material Adverse Effect.

Section 5.7.  Adequate Information. Each Contributor is informed of the
financial condition and prospects of the Company and has reviewed and is
familiar with the terms of the Indenture Documents that are material to its
obligations hereunder.

ARTICLE VI.
COVENANTS

Each Contributor covenants and agrees to comply with the following covenants at
all times prior to the Termination Date:

Section 6.1. Dispositions. Such Contributor shall not sell or transfer any
portion of its Proportionate Interest, or consent to the issuance by the Company
of any additional equity interests of the Company, in either case to any Person,
except pursuant to a Permitted Transfer. For purposes of this Section, a
“Permitted Transfer” shall include any such sale or transfer (i) to a
Contributor or a wholly-owned subsidiary of a Contributor, (ii) to a Person
which has an Investment Grade rating for either (x) its corporate credit rating
or (y) its long-term, senior unsecured and unguaranteed debt, or which has a
direct or indirect parent with either of such Investment Grade ratings and of
which it is a majority owned subsidiary and that shall have assumed in writing
or by operation of law all of such Contributor’s obligations hereunder, or (iii)
if a Ratings Reaffirmation is obtained in connection with such sale or transfer
from at least one of Moody’s or S&P; in each case, where such buyer, transferee
or parent has executed and delivered a Joinder on or prior to the date of such
sale or transfer in accordance with and to the extent required under Section
7.14. For the avoidance of doubt, this Section shall not prohibit the issuance
of equity interests by any Contributor. A transfer by a Contributor of a portion
of its Proportionate Interest will result in a proportionate reduction in the
amount of its Equity Contribution Undertaking.

Section 6.2.  Further Assurances. Such Contributor shall perform, upon the
reasonable request of the Trustee, all reasonable acts incidental to such
Contributor’s obligations under this Agreement as may be necessary to carry out
its obligations in accordance with the intent of this Agreement, provided that
in no case shall any Contributor be required to make any payment or provide any
financial consideration in excess of that required under the other provisions of
this Agreement.

the Pipeline Owners. Any previous agreement, whether written or oral, among the
parties or their Affiliates with respect to the subject matter hereof is
superseded by this Agreement.

Section 7.3.  Severability.  In case any provision in or obligation hereunder
shall be invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions or obligations shall not
in any way be affected or impaired thereby. If any such provision of this

negotiate in good faith new provisions to eliminate such invalidity and to

Section 7.4.  Headings.  Article and Section headings and the Table of Contents
used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

Section 7.5.  GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND

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

SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES THAT WOULD RESULT IN THE
APPLICATION OF ANY LAW OTHER THAN THE LAW OF THE STATE OF NEW YORK.

Section 7.6.  Jurisdiction. Each party hereto hereby irrevocably and
unconditionally submits, for itself and its property, to the exclusive
jurisdiction of any New York State court or federal court of the United States
of America sitting in New York City, and any appellate court from any thereof,
in any action or proceeding arising out of or relating to this Agreement, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State
Court or, to the extent permitted by law, in such federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Each party hereto hereby
irrevocably and unconditionally waives, to the fullest extent it may legally and
effectively do so, any objection which it may now or hereafter have to the
laying of venue of any suit, action or proceeding arising out of or relating to
this Agreement in any New York State or federal court. Each of the parties
hereto hereby irrevocably waives, to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court.

Section 7.7. WAIVERS. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT
OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION
WITH THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE,
THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION 7.7.

Section 7.8.  Amendments; Joinders. No amendment, supplement or waiver of any
provision of this Agreement nor consent to any departure by any of the parties
hereto from any provision of this Agreement shall in any event be effective
unless the same shall be in writing and signed by each of the parties hereto.
Any such amendment, supplement, waiver or consent shall be effective only in the
specific instance and for the specified purpose for which given. Notwithstanding
the foregoing, without the consent of any party hereto, any additional
Contributor may become a party hereto by execution and delivery of a Joinder in
accordance with Section 7.14 and, upon such execution and delivery, such
additional Contributor shall be subject to the terms hereof.

Section 7.9.  Assignments. This Agreement and the rights, interests or
obligations hereunder may not be assigned by any of the parties hereto without
the prior written consent of the other parties hereto; provided, however, that
each Contributor may, without consent of the other parties hereto, assign its
rights under this Agreement as permitted under Section 6.1. For the avoidance of
doubt, any Contributor that validly assigns all of its Proportionate Interest to
another Person in accordance with this Agreement shall be automatically released
from its

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

obligations hereunder. This Agreement shall inure to the benefit of and be
binding upon each Contributor, the Company and the Trustee (on behalf of the
Indenture Parties), and their respective successors and permitted assigns.
Nothing in this Agreement will confer upon any Person not a party to this
Agreement, or the legal representatives of such person or entity, any rights or
remedies of any nature or kind whatsoever under or by reason of this Agreement.
Any purported assignment of this Agreement in violation of this Section 7.9
shall be null and void ab initio and shall be ineffective to relieve any party
of its obligations hereunder.

Section 7.10.  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered shall be deemed an
original, but all such counterparts together shall constitute but one and the
same instrument. Delivery of an executed counterpart to this Agreement by
facsimile transmission or electronic transmission in “.pdf” format shall be as
effective as delivery of a manually signed original.

Section 7.11.  No Waiver. No failure on the part of the Trustee to exercise, and
no delay in exercising, any right, power or remedy hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right,
power or remedy by the Trustee preclude any other or further exercise thereof or
the exercise of any other right, power or remedy. All remedies hereunder are
cumulative and are not exclusive of any other remedies provided by Applicable
Law. The Trustee shall not be deemed to have waived any rights hereunder or
under any other agreement or instrument unless such waiver shall be in writing
and signed by the Trustee.

Section 7.12. Specific Performance.  To the extent it may do so under applicable
Applicable Law, the Trustee may, pursuant to instructions from the Required
Noteholders and upon being provided indemnity other security for the
reimbursement of all expenses to which it may be put to protect it from
liability, institute an action for specific performance of this Agreement. Each
Contributor hereby irrevocably waives, to the extent it may do so under
applicable Applicable Law, any defense based on the adequacy of a remedy at law
that may be asserted as a bar to the remedy of specific performance in any
action brought against such Contributor for specific performance of this
Agreement by the Trustee or for its benefit by a receiver, custodian or trustee
appointed for the Company or either Pipeline Owner, or in respect of all or a
substantial part of their respective assets, under any Bankruptcy Law. The
Trustee shall not be required to post a bond or other security in connection
with an action for specific performance of this Agreement.

Section 7.13.  Termination. Notwithstanding any provision hereof to the contrary
(but subject to Section 4.4), this Agreement and the obligations of the Company
and each Contributor hereunder shall terminate on the earliest to occur of (a)
the date upon which the Contingent Equity Undertaking has been fully funded, (b)
the Required Contribution Termination Date, (c) with respect to a Series of
Notes, upon satisfaction and discharge of the Indenture with respect to such
Series of Notes in accordance with the Indenture, (d) upon Legal Defeasance or
Covenant Defeasance in accordance with (and each as defined in) the Indenture,
and (e) as to any Contributor, upon the transfer of all of such Contributor’s
Proportionate Interest in the Company in compliance with Sections 6.1 and 7.9
(such earliest date, the “Termination Date”), and all obligations of any
Contributor, including obligations under Section 6.1, obligations to make any
Equity Contribution pursuant to any other Indenture Document, or otherwise,
shall be deemed to be automatically cancelled on the Termination Date.

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

Section 7.14.  Additional Contributors. To the extent any Contributor transfers
any portion of its Proportionate Interest in accordance with Sections 6.1 and
7.9, the transferee thereof (or its direct or indirect parent as described in
Section 6) shall accede as a Contributor to this Agreement (each, a “Joining
Contributor”) by executing and delivering an instrument substantially in the
form of Annex I (a “Joinder”) (with such changes as may be reasonably
satisfactory to the Company and the Trustee) pursuant to which such Joining
Contributor becomes a Contributor hereunder, subject hereto and bound hereby;
provided, however, that such transferee or parent shall not be required to
accede as a Contributor to this Agreement if such transferee is a Contributor or
if a Ratings Reaffirmation is obtained in connection with such sale or transfer
from one of Moody’s or S&P without such transferee so acceding as a Contributor.

Section 7.15.  The Trustee. The Trustee will act only as specifically provided
herein and in the Indenture. No implied covenants shall be read into this
Agreement against the Trustee. The Trustee is entering into this Agreement
solely in its capacity as Trustee under the Indenture, and the duties, powers,
rights and obligations of the Trustee in acting hereunder will be subject to the
provisions of the Indenture, all of which are incorporated by reference herein.
The incorporated provisions of the Indenture are intended to survive the
retirement of the Notes and the termination and discharge of the Indenture.

the Pledgor, the “Pipeline Owners”), each of the Contributors party thereto,
U.S. Bank National Association as the Trustee under the Indenture referenced in
the ECA (in such capacity, together with any successor Trustee appointed
pursuant to the Indenture, the “Trustee”).
A. Capitalized terms used herein but not otherwise defined herein shall have the
meanings assigned to such terms in the ECA.

B. As a condition to the ability of any Contributor to transfer any equity
interest, direct or indirect, in the Company, the purchaser of such interest or
its direct or indirect parent, as described in section 6.1 of the ECA is
required to become subject to and bound by the ECA. Section 7.14 of the ECA
provides that such Joining Contributor may become a Contributor, subject to and
bound by, the ECA, upon the execution and delivery by the Joining Contributor of
an instrument in the form of this Joinder. The undersigned Person (the “Joining
Contributor”) is executing this Joinder in accordance with such requirements of
the ECA.

Accordingly, the Joining Contributor agrees as follows:

SECTION 1. In accordance with Section 7.14 of the ECA, the Joining Contributor
by its signature below becomes a Contributor under, subject to and bound by, the
ECA with the same force and effect as if the Joining Contributor had originally
been named therein as a Contributor, and the Joining Contributor hereby agrees
to all the terms and provisions of the ECA applicable to it as a Contributor.
Each reference to a “Contributor” in the ECA shall be deemed to include the
Joining Contributor. The ECA is hereby incorporated herein by reference.
Immediately following the execution of the Joinder, the Proportionate Interest
of the Joining Contributor is [___]% .

SECTION 2. The Joining Contributor represents and warrants to the Trustee that
(i) it has full power and authority to enter into this Joinder, and (ii) this
Joinder has been duly authorized, executed and delivered by it and constitutes
its legal, valid and binding obligation, enforceable against it in accordance
with the terms of this Joinder and the ECA.

SECTION 3. This Joinder may be executed in counterparts, each of which shall
constitute an original, but all of which when taken together shall constitute a
single contract. This Joinder shall become effective when the Company and the
Trustee shall have received a counterpart of this Joinder that bears the
signature of the Joining Contributor. Delivery of an executed signature page to
this Joinder by facsimile or electronic transmission shall be effective as
delivery of a manually signed counterpart of this Joinder.

SECTION 4. Except as expressly supplemented hereby, the ECA shall remain in full
force and effect.

SECTION 5. THIS JOINDER AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER
SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES
THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAW OF THE STATE
OF NEW YORK.

SECTION 6. In case any one or more of the provisions contained in this Joinder
should be held invalid, illegal or unenforceable in any respect, no party hereto
shall be required to comply with such provision for so long as such provision is
held to be invalid, illegal or unenforceable, but the validity, legality and
enforceability of the remaining provisions contained herein and in the ECA shall
not in any way be affected or impaired. The parties hereto shall endeavor in
good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

SECTION 7. All communications and notices hereunder shall be in writing and
given as provided in Section 7.1 of the ECA. All communications and notices
hereunder to the Joining Contributor shall be given to it at the address set
forth below its signature hereto.

SECTION 8. The Company agrees to reimburse the Trustee for its reasonable and

reasonable fees, other charges and disbursements of counsel for the Trustee.
