RIO TINTO ENERGY AMERICA COAL SUPPLY AGREEMENT

 

This
Rio Tinto Energy America Coal Supply Agreement (the “Agreement”),
made this 19th day of November, 2009 (the “Effective Date”),
is by and between Cloud Peak Energy Resources LLC, a Delaware limited liability
company (“CPE LLC” or the “Company”), and Rio Tinto Energy
America Inc., a Delaware corporation (“RTEA”).  CPE LLC and RTEA are each referred to herein
as a “Party” and collectively as the “Parties.”

 

W I T N E S S E T H:

 

WHEREAS,
through a series of structuring transactions, RTEA contributed RTA’s non-Colorado
Western United States coal mining business (other than the Colowyo mine) to the
Company and have entered into a Master Separation Agreement, dated as of November 19,
2009 (the “Master Separation Agreement”),
by and between the Parties and their affiliated companies;

 

WHEREAS,
the Parties have determined that the direct transfer of certain coal sales
contracts (the “Coal Sale Contracts”)
of varying duration for the sale or purchase of coal that is produced from the
Antelope Mine, the Cordero Rojo Mine and/or the Spring Creek Mine (together the
“Mines”), to various purchasers (the
“Counterparties”) as more fully
described and listed on Exhibit A attached hereto (the “Listed Contracts”), from RTEA to
CPE LLC is impractical or otherwise undesirable; and

 

WHEREAS,
to the fullest extent possible, in order to provide the economic benefit and
risks to CPE LLC of the Listed Contracts to the same extent as if those Listed
Contracts had been fully assigned to CPE LLC, the Parties desire to enter into
this Agreement;

 

NOW
THEREFORE, for and in consideration of the amounts to be paid and the promises
contained herein, and for other good and valuable consideration, the receipt
and sufficiency of which is hereby acknowledged and intending to be legally
bound, the Parties agree as follows:

 

1.               Performance Obligations of
CPE LLC.

 

a.               Commencing as
of the Effective Date and except as otherwise set forth in this Agreement, CPE
LLC shall sell to RTEA, and RTEA shall
purchase from CPE LLC, all the coal required to be supplied by RTEA
under each of the Listed
Contracts, in such quantities, qualities, prices and time frames and in
accordance with such other terms as RTEA is required to sell such coal to the
Counterparties under the Listed Contracts. 
CPE LLC hereby dedicates to this
Agreement such quantity of coal reserves at each of the Mines as is required
for the full performance of its obligations under this Agreement, and covenants
that coal from said reserves will not be sold or contracted for sale in such
quantity and quality as to jeopardize its ability to deliver the total quantity
and quality of coal called for by this Agreement.

 

Further, CPE LLC shall
perform all the duties and obligations of RTEA or its Affiliates under the
Listed Contracts which are necessary for the full and proper performance

 

1

 

of RTEA’s or its Affiliate’s covenants,
obligations and responsibilities for delivery of coal to the Counterparties
under the Listed Contracts after the Effective Date (“RTEA’s
Contract Obligations”). 
RTEA’s Contract Obligations include, but are not limited to, the sourcing, processing, loading,
sampling, analysis, weighing, scheduling, transportation and delivery of coal
as required of RTEA under the Listed Contracts and the scheduling of any
shipments of coal, as well as any and all administrative responsibilities of
RTEA required for performance of all of RTEA’s Contract Obligations, including
without limitation, invoicing the coal sales; provided, however, all invoices
shall provide for payment to RTEA.  For
so long as this Agreement is in effect, CPE LLC shall have reasonable access to
the applicable RTEA accounts receivable data,
in electronic form, as necessary for CPE LLC to prepare and send the
invoices to the Counterparties.

 

b.              With respect to
each of the Listed Contracts, if CPE LLC fails for any reason (including
without limitation as a result of an event of force majeure (as defined in the
applicable Listed Contract)) to supply and/or deliver on a timely basis any
amount of coal called for under any such Listed Contract, CPE LLC, not RTEA,
shall have the obligation to make all necessary substitute arrangements in
order to supply the coal required under such Listed Contract and shall
otherwise bear any financial and other responsibility related thereto.

 

c.               The Parties
agree that CPE LLC shall assume responsibility for all Listed Contracts whether
that obligation is to produce the coal or to purchase the coal from a
Counterparty.

 

d.              The Parties
also agree that certain Listed Contracts may have separate parental guarantees
for which RTEA or its affiliates have responsibility.  CPE LLC agrees to use commercially reasonable
efforts to replace these guarantees as soon as practicable.  In the event these guarantees cannot be
replaced, or if CPE LLC is required to expend significant monies to replace
these guarantees, CPE LLC shall not replace these guarantees but agrees to
indemnify, without limitation, RTEA and its Affiliates for any future losses
incurred as a result of such guarantees.

 

e.                                       The Parties
also agree that the confirmation(s) and master agreement related to Salt
River Project Agricultural Improvement and Power District which are not a
Listed Contract may have a separate parental guaranty for which RTEA or its
Affiliates have responsibility.  CPE LLC
agrees to use commercially reasonable efforts to replace this guaranty as soon
as practicable.  In the event this
guaranty cannot be replaced, or if CPE LLC is required to expend significant
monies to replace this guaranty, CPE LLC shall not replace this guaranty but
agrees to indemnify, without limitation, RTEA and its Affiliates for any future
losses incurred as a result of such guaranty.

 

2.               Administration.

 

a.               As of the
Effective Date, subject to the terms and conditions contained below, CPE LLC is
authorized to exercise all rights and take all actions RTEA or its Affiliates
is entitled to exercise or take under the Listed Contracts (“RTEA’s Contract Rights”), without
the need for further notification to or approval from RTEA.  By way of example and without limitation,
RTEA’s Contract Rights shall include: (i) communicating directly with the
Counterparties, shippers, federal, state and local governmental authorities and
other third 

 

2

 

parties in connection with
the performance of RTEA’s Contract Obligations; (ii) monitoring the
performance of the Counterparties; and (iii) reviewing and auditing all
payments and related documentation rendered by the Counterparties, provided
however, that CPE LLC shall promptly provide RTEA with copies of any
information, notices and other communications with Counterparties reasonably
requested by RTEA for the purpose of performing its accounting and financial
reporting functions and to meet RTEA’s obligations under the Listed
Contracts.  Notwithstanding the
foregoing, should a Counterparty refuse to communicate with CPE LLC on any
matters relating to the relevant Listed Contract, RTEA shall upon CPE’s written
request communicate directly with such Counterparty on such matters as
necessary to assist CPE LLC in performance of its obligations hereunder.

 

b.              Notwithstanding
the foregoing, neither RTEA nor any of its Affiliates shall agree to any
termination, suspension, amendment, modification, waiver, forgiveness or
forbearance of any provision of or any right under the Listed Contracts (an “Amendment”) without the prior
written consent of CPE LLC pursuant to this Agreement.

 

c.               In the event
CPE LLC seeks RTEA’s consent to an Amendment to a Listed Contract, RTEA shall
agree to such amendment and/or shall use commercially reasonable efforts to
obtain the relevant Counterparty’s agreement to such Amendment; provided that
CPE LLC shall reimburse RTEA for its reasonable costs and expenses incurred in
obtaining such Amendment and provided further that RTEA shall have no
additional liability or duties as a result of such Amendment.

 

d.              In the event
CPE LLC desires to take actions under a Listed Contract that requires the
Counterparty’s consent, RTEA shall use commercially reasonable efforts to
obtain the relevant Counterparty’s consent; provided that CPE LLC shall
reimburse RTEA for its reasonable costs and expenses incurred in obtaining such
consent and the same shall be subject to the indemnification obligations in
favor of RTEA as provided in Section 6 below.

 

e.               To the extent
permissible under the Listed Contracts and under applicable Law, RTEA shall
provide CPE LLC reasonable access to (including copies of) all information RTEA
now has or hereafter acquires with respect to each such Listed Contract,
provided that CPE LLC agrees to be subject to any confidentiality provisions of
any such contract with respect to such information.  Each party also agrees to participate and
fully and promptly cooperate, at the request of the other party, in any
governmental proceeding or contractual dispute with respect to the Listed
Contracts.

 

f.                 If a dispute
arises between CPE LLC or RTEA and a Counterparty with respect to any of the
Listed Contracts, or if a Counterparty fails to perform any of their
obligations under any such Listed Contract, each party shall take the steps
reasonably requested by the other party to enforce RTEA’s rights under such
Listed Contract, at CPE LLC’s sole risk, cost and expense.  In the event of any such request from RTEA,
CPE LLC shall pay any and all reasonable costs and expenses (including, without
limitation, attorneys’ fees and expenses) incurred by RTEA in attempting to
enforce its rights.

 

g.              The Parties
acknowledge and agree that CPE LLC shall act hereunder as an independent
contractor and not as RTEA’s agent and that CPE LLC shall have no right,
authority or power

 

3

 

to obligate or bind RTEA in
any manner hereunder or under any of the Listed Contracts except as provided
herein.  So long as no default by CPE LLC
under this Agreement has occurred and is continuing, RTEA shall not do anything
to interfere with CPE’s performance under this Agreement.

 

h.              The Parties do
not intend this Agreement to be construed as or constitute an assignment of the
Listed Contracts by RTEA to CPE LLC.

 

i.                  Until the
assignment by RTEA to CPE LLC of any particular Listed Contract, RTEA shall
forward to CPE LLC as soon as reasonably possible a copy of any written or
electronic correspondence, notice or other communication received from any
Counterparty which is directly related to or materially affects a Listed
Contract that is received by RTEA from the applicable Counterparty.

 

3.                                       Consideration.  As payment for the sale of coal and, the
services to be performed by CPE LLC hereunder, RTEA shall pay to CPE LLC an
amount (the “Fee”) equal to all payments
actually received by RTEA from the Counterparties for coal delivered under the
Listed Contracts after the Effective Date. 
To the maximum extent practicable, the Parties shall designate CPE LLC
as collection agent for the Listed Contracts and/or establish one or more
segregated accounts into which Counterparty payments for the Listed Contracts
will be made, and which will be available to CPE LLC for purposes of
withdrawal.  For those Counterparties for
which such accounts are not practicable, RTEA will remit amounts received by such
Counterparties as soon as reasonably practical after the same are received and
verified, but in any event, at least semi-monthly.

 

4.                                       Term of Agreement.  The term of this Agreement shall commence on
the Effective Date, and shall remain in effect with respect to each of the
Listed Contracts until both Parties have performed their covenants hereunder
with respect to that Listed Contract and such Listed Contract has been
eliminated from Exhibit A as provided in Section 5;
provided, however, the indemnification obligations shall survive through the
applicable statute of limitations.

 

5.                                       Termination of Obligations With Respect to Listed Contracts.  Upon the earliest to occur of: (i) receipt
of the consent or approval for the formal assignment of a Listed Contract to
CPE LLC and the execution of a written agreement mutually agreeable to RTEA and
CPE LLC effectuating such assignment; (ii) the full performance and
expiration of a Listed Contract pursuant to its terms (including but not
limited to obligations which survive delivery of the coal under such Listed
Contract); and (iii) the termination of a Listed Contract for any reason, Exhibit A
hereto shall automatically be amended to eliminate the Listed Contract that has
been assigned, fully performed or terminated, and (with the exception of the
indemnification obligations under Section 6 below with respect to
such Listed Contract, which obligations shall survive such an event, as well as
the termination of this Agreement) said Listed Contract shall no longer be subject
to this Agreement.

 

4

 

6.               Indemnification
Obligations of CPE LLC and RTEA.

 

a.               CPE LLC shall,
indemnify, defend, and save harmless RTEA, its parent, subsidiaries and
Affiliates and each of their respective officers, directors, employees, agents
and invitees (the “RTEA Indemnified Persons”)
from and against any and all Liability (as defined below) arising out:  (i) the performance of this Agreement on
the part of CPE LLC, its Affiliates and any of their respective employees,
contractors or representatives; (ii) any default, breach, or
non-fulfillment of any covenant, obligation or agreement by CPE LLC under this
Agreement; or any default, breach, or non-fulfillment of any representation,

their respective employees, contractors or representatives (other than CPE LLC
or RTEA); and (iii) in either (i) or (ii), which is not cured within
five (5) days after written notice of such failure is given to CPE LLC in
the case of any failure to pay when due or in any other case, within thirty
(30) days after written notice, or if not curable within thirty (30) days, if such
cure is not promptly commenced and diligently prosecuted, or in the case of any

shall not include any obligation to indemnify any RTEA Indemnified Person from
any gross negligence or willful misconduct by the RTEA Indemnified Person.

 

b.              RTEA shall
indemnify, defend, and save harmless CPE LLC, its parent, subsidiaries and
Affiliates and each of their respective officers, directors, employees, agents

Persons”) from and against any and all Liability that CPE LLC
Indemnified Persons may incur resulting by reason of or arising out of (i) the
failure to perform this Agreement on the part of RTEA, its employees,
contractors or representatives (other than any CPE LLC Indemnified Person); or (ii) any
default, breach, or non-fulfillment of any covenant, obligation or agreement by
RTEA under this Agreement; and (iii) in either (i) or (ii), which is

given to RTEA in the case of any failure to pay when due or in any other case,
within thirty (30) days after written notice, or if not curable within thirty
(30) days, if such cure is not promptly commenced and diligently prosecuted;
provided, however that the indemnification obligations shall not include any
obligation to indemnify any CPE LLC Indemnified Person from any gross
negligence or willful misconduct by the CPE LLC Indemnified Person.

 

c.               For purposes of
this Agreement, the term “Indemnified Persons”
means any of the RTEA Indemnified Persons or the CPE LLC Indemnified Persons,
as the case may be; the term “Liability”
means any loss, whether in the nature of a cost, damage, expense, fine,
payment, diminution in value, loss, or liability (whether actual, contingent or
otherwise, but in each case, excluding any consequential, special, incidental
or punitive damages other than may be asserted by a third party), including (i) any
amount payable in settlement of any Claim (as defined below), or any amount
payable under or in connection with any decree, judgment, order, stay, writ or
other judicial, mediation, arbitral or other legal determination, and (ii) reasonable
fees and expenses of attorneys, other professionals, and experts (including in
respect of any investigation, prosecution or defense of a Claim), and (iii) in

indemnity pursuant to the terms of this 

 

5

 

Agreement, a written Notice
of such Claim from the Indemnified Person to the indemnifying Party specifying
in reasonable detail the specific nature of and specific basis of the Claim and
the estimated amount of Liability for which the Indemnified Person seeks
indemnification in connection with such Claim.

 

d.  Any indemnification obligation of CPE LLC
arising under this Section 6 will be calculated and payable in
accordance with Section 6.1 of the Master Separation Agreement.

 

7.                                       Nature of
Indemnification.  The Parties
agree that the indemnification obligations are integral parts of this Agreement
and that consideration has been provided therefore.  This Agreement and the indemnification
obligations given hereunder are freely and voluntarily given, and the Parties
acknowledge and represent that they have fully reviewed the terms contained
herein, that they are fully informed with respect to the legal effect of this
Agreement, and that they have voluntarily chosen to accept the terms and
conditions hereof.

 

8.                                       Indemnification
Procedures.  The
following procedures shall apply in respect of any claim by an Indemnified
Person for indemnification arising hereunder:

 

a.               As promptly as
practical, but in any event within thirty (30) Business Days after receipt by
an Indemnified Person of notice of a Claim by any third party (a “Third Party Claim”) or after such
Indemnified Person obtains actual knowledge of the existence of a Claim other
than a Third Party Claim, in each case with respect to which such Indemnified
Person may be entitled to receive indemnification from the other Party for any
Liability, such Indemnified Person shall provide a Claim Notice to the
indemnifying Party; provided, however, that the failure to provide a Claim Notice to the
indemnifying Party shall relieve the indemnifying Party from Liability under
this Agreement with respect to such Third Party Claim only if, and only to the
extent that, such failure to provide a Claim Notice to the indemnifying Party
results in (i) the forfeiture by the indemnifying Party of rights and
defenses otherwise available to the indemnifying Party with respect to such
Third Party Claim; or (ii) material prejudice to the indemnifying Party
with respect to such Third Party Claim.

 

b.              The
indemnifying Party shall have the right, upon Notice (as defined below)
delivered to the Indemnified Person within thirty (30) days after receipt of a
Claim Notice, to assume the defense and control of such Third Party Claim,
including the employment of its choice of counsel; provided,
however, that the indemnifying Party shall not be entitled to assume
the defense of any Third Party Claim alleging any criminal or
quasi-criminal wrongdoing (including fraud). 
If the indemnifying Party declines or fails to assume the defense of the
Third Party Claim on the terms herein provided within such thirty (30) day
period, the Indemnified Person may employ counsel to represent or defend it in
any such Third Party Claim and the indemnifying Party shall pay the reasonable
fees and disbursements of such counsel as incurred.  In any Third Party Claim with respect to
which indemnification is being sought hereunder, RTEA or CPE LLC whichever is
not assuming the defense of such Third Party Claim, shall have the right to
participate in such matter and to retain its own counsel at such Party’s own
expense.  The Party that has assumed
defense of a Third Party Claim, whether the indemnifying Party or the
Indemnified Person, as the case may be, shall at all times use commercially
reasonable efforts to keep the other Party reasonably apprised of the status of
the defense against the Third Party Claim and to cooperate in good faith with
the 

 

6

 

other Party with respect to
the defense of any such Third Party Claim. 
No Party may settle or compromise any Third Party Claim or consent to
the entry of any judgment in connection with any Third Party Claim with respect
to which indemnification is being sought hereunder without the prior written
consent of the other Party, which consent may be withheld only where such Party
would be materially negatively impaired by such settlement, compromise or
consent to entry of judgment.

 

c.               The provisions
of this Section 8 shall survive expiration or earlier termination
of this Agreement, including any termination with respect to any Listed
Contract.

 

9.                                       Notices.  All
notices, requests, demands, waivers and other communications required or
permitted to be given under this Agreement (each a “Notice”)
shall be in writing and shall be given by any of the following methods:  (a) personal delivery; (b) registered
or certified mail, postage prepaid, return receipt requested; (c) facsimile,
receipt confirmed; or (iv) by a nationally recognized overnight courier
service.  Notices shall be sent to the

and confirmation is received; in both such cases if given on a business day
during the normal business hours of the recipient and on the business day
during which such normal business hours next occur if not given during such
hours.

 

10.                                 Severability.  If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of
law or public policy, all other terms, conditions and provisions of this
Agreement shall nevertheless remain in full force and effect so long as the
economic or legal substance hereof is not affected in any manner materially
adverse to any Party.  Upon such
determination that any term or other provision is invalid, illegal or incapable
of being enforced, the Parties shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the Parties as closely as
possible in a mutually 

 

7

 

acceptable manner in order
that the transactions contemplated hereby be implemented as originally
contemplated to the fullest extent possible.

 

11.                                 Binding Effect; Assignment.  Subject to the provisions of Section 6(a) and
so long as no default has occurred and is continuing by CPE LLC with respect to
this Agreement, and to secure its performance obligations hereunder, RTEA
hereby collaterally assigns to CPE LLC all payments to be received by RTEA from
any of the Counterparties under the Listed Contracts.  In addition to the foregoing, this Agreement
and all of the provisions hereof shall be binding upon and shall inure to the
benefit of the Parties and their respective successors and permitted
assigns.  RTEA may assign or otherwise
transfer, directly or indirectly, all or any portion of its rights, interests
or obligations hereunder to any one or more Affiliates, but such assignment or
transfer shall not be binding upon CPE LLC until Notice to CPE LLC is given of
such assignment or transfer.  Except as
otherwise set forth in this Section 11, neither this Agreement nor
any of the rights, interests or obligations hereunder shall be assigned,
directly or indirectly, by any Party without the prior written consent of the
other Party; provided, however, that the
foregoing shall not require any consent upon the sale of all or substantially
all of the assets and equity interests of RTEA or CPE LLC, as the case may be,
by its respective corporate parent.

 

12.                                 No Third Party Beneficiaries.  This Agreement is exclusively for the benefit
of RTEA, and its Affiliates, successors and permitted assigns, with respect to
the obligations of CPE LLC under this Agreement, and for the benefit of CPE
LLC, and its Affiliates, successors and permitted assigns, with respect to the
obligations of RTEA under this Agreement, and this Agreement shall not be
deemed to confer upon or give to any other third person any remedy, claim,
liability, reimbursement, cause of action or other right.

 

13.                                 Dispute Resolution.  If any dispute between the Parties arises
concerning or relating to this Agreement, other than any default in making a
payment when due, then senior management personnel of each of the Parties shall
meet and confer in a good faith effort to resolve the same.  If the dispute is not resolved within thirty
(30) days after the time it is referred to the senior management personnel,
either Party may initiate litigation with respect to the dispute.

 

14.                                 Governing Law; Submission to Jurisdiction; Waiver of Jury Trial.  Disputes arising between the Parties arising
from this Agreement shall be in accordance with clause 9.6 of the Master
Separation Agreement, which is hereby incorporated by reference.  The parties explicitly agree that the United
Nations Convention for the Sale of Goods and the convention on Agency in the
International Sale of Goods, shall have no application to this Agreement.

 

15.                                 Counterparts.  This Agreement may be executed in
counterparts, each of which shall be deemed to be an original, but all of which
shall constitute one and the same agreement and shall become effective when one
or more counterparts have been signed by each of the Parties and delivered
(including by facsimile) to the other Party.

16.                                 Amendment; Modification.  Except as expressly provided in this
Agreement, this Agreement may not be amended, modified or supplemented at any
time except in a writing signed by the Parties.

 

17.                                 Capitalized Terms.  Any capitalized terms not otherwise defined
herein shall have the same meanings as defined in the Master Separation
Agreement or, if such terms relate to a Listed Contract shall have the meaning

This
TAX RECEIVABLE AGREEMENT (as amended from time to time, this “Agreement”),
dated as of November 19, 2009, is hereby entered into by and among Cloud
Peak Energy Inc., a Delaware corporation (“Buyer”) and Rio Tinto Energy
America, Inc., a Delaware corporation (“RTEA”).

 

RECITALS

 

WHEREAS, RTEA and its
Affiliates hold membership units of Cloud Peak Energy Resources LLC, a Delaware
limited liability company (“CPE LLC”), and RTEA is selling some of its
membership units to Buyer (including any exercise by the underwriter of its
overallotment option, the “Initial Sale”) as described in the
Registration Statement;

 

WHEREAS, CPE LLC and
several of its Subsidiaries are Partnerships;

 

WHEREAS, after the
Initial Sale, Buyer will be the managing member of CPE LLC, and will therefore
have Control of CPE LLC and its Subsidiaries, and CPE LLC and its Subsidiaries
will become Subsidiaries of Buyer;

 

WHEREAS, the RTEA
Units are redeemable, at the option of their holders, for cash from CPE LLC,
and upon the exercise of such redemption right, Buyer will have the right to
assume the rights and obligations of CPE LLC with respect to the RTEA Units
being redeemed (the “Buyer Assumption Right”) and to thereby acquire
such RTEA Units in exchange for cash or common stock of Buyer;

 

WHEREAS, Buyer
will take a “cost” tax basis in the RTEA Units acquired in the Initial Sale,
and Buyer’s tax basis in the RTEA Units acquired in the Initial Sale is
expected to exceed RTEA’s tax basis in such RTEA Units prior to the Initial
Sale;

 

WHEREAS, pursuant
to the Third Amended and Restated Limited Liability Company Agreement of CPE
LLC, dated November 19, 2009 (the “CPE LLC Agreement”), CPE LLC and each
of its Subsidiaries that is a Partnership will have in effect or make an
election under Section 754 (a “Section 754 Election”) of the
Internal Revenue Code of 1986, as amended (the “Code”), for the Taxable
Year in which the Initial Sale occurs and for each Taxable Year in which an
Exchange occurs;

 

WHEREAS, the
structure of the Initial Sale and the Section 754 Elections of CPE LLC and
each of its Subsidiaries that is a Partnership are intended generally to result
in an adjustment (with respect to the Section 754 Elections, such
adjustment will be solely with respect to Buyer) to the tax basis of the
Adjustable Assets as a result of the Initial Sale, of any subsequent Exchange,
or of the receipt of payments under this Agreement;

 

WHEREAS, the
income, gain, loss, expense and other Tax items of (i) CPE LLC solely with
respect to Buyer may be affected by the Basis Adjustment and (ii) Buyer
may be affected by the Basis Adjustment and the Imputed Interest; and

 

WHEREAS, the
parties to this Agreement desire to make certain arrangements with respect to
the effect of the Basis Adjustment and Imputed Interest on the actual liability
for Taxes of the Buyer;

 

NOW, THEREFORE, in
consideration of the foregoing and the respective covenants and agreements set
forth herein, and intending to be legally bound hereby, the parties hereto agree
as follows:

 

ARTICLE I

DEFINITIONS

 

Section 1.01.                       Definitions.  As used in
this Agreement, the terms set forth in this Article I shall have the
following meanings (such meanings to be equally applicable to both the singular
and plural forms of the terms defined).

 

“Accelerated
RTEA Gain” is defined in Section 4.04(a)(4).

 

1

 

“Accounting Firm” means a nationally recognized, independent
accounting firm, selected by RTEA, with experience in natural resource taxation
matters.

 

“Actual/Modified
Payment Difference” means, with respect to a Taxable Year, (i) the
payments RTEA actually received under this Agreement with respect to such
Taxable Year pursuant to Section 3.01(a) (excluding any Interest
Amounts received, and any interest received pursuant to Section 5.01);
minus (ii) the payments that Buyer actually received under this Agreement
with respect to such Taxable Year pursuant to Section 3.01(a) (excluding
any Interest Amounts received, and any interest received pursuant to Section 5.01);
minus (iii) the net payment that the Projected Tax Benefit Schedule
predicted that Buyer would have made to RTEA for such Taxable Year (without
regard to the Assumed Administrative Cost for such Taxable Year).  For the avoidance of doubt, the
Actual/Modified Payment Difference may be a negative number.

 

“Actual
Buyer Tax Liability” for any Taxable Year means the total liability for
Taxes of Buyer, as indicated on the Tax Returns filed by Buyer (including any
consolidated return in which Buyer joins) for such Taxable Year, taking into
account any Determinations and adjusted to reflect U.S. federal income tax
rates that are one percent higher than the actual U.S. federal income tax rates
to which Buyer is subject for such Taxable Year. Notwithstanding the foregoing,
the Actual Buyer Tax Liability for any Taxable Year shall also include any
corollary adjustments to reflect any tax items for such Taxable Year that Buyer
would have incurred as a result of any transactions deemed to occur by virtue
of Section 4.04(a) or Section 4.04(b).

 

“Adjustable
Asset” means the RTEA Units and any asset other than cash owned by CPE LLC,
either directly or indirectly through one or more Partnerships or entities that
are disregarded for U.S. federal income tax purposes.

indirectly, through one or more intermediaries, Controls, is Controlled by, or
is under common Control with, such first Person.

“Agreement”
is defined in the Recitals of this Agreement.

 

“Alternative
Tax Benefit Payment” means, with respect to a Taxable Year and a particular
Adjustable Asset that has been transferred in a Non-Exempted Transfer that was not
currently fully taxable, the Tax Benefit Payment that would be due in that
Taxable Year if, starting in the Taxable Year in which such transfer took
place, such Adjustable Asset had produced the tax items it would have produced
had such transfer not occurred instead of the tax items that it actually
produced.

 

“Amended
Schedule” is defined in Section 2.05(b).

 

“Assumed
Administrative Cost” means the average cost incurred by RTEA pursuant to Section 2.06,
calculated with respect to the most recent three Taxable Years preceding an
Early Termination Notice Date for which a Tax Benefit Schedule has become final
pursuant to Section 2.05(a).  If an
Early Termination Notice Date occurs prior to the finalization of Tax Benefit
Schedules pursuant to Section 2.05(a) with respect to three Taxable
Years, then the Assumed Administrative Cost shall be $25,500.

 

“Average
Maximum RTEA Tax Rate” means, as of any given date, the arithmetic mean of
the various Maximum RTEA Tax Rates to which RTEA has been subject during the
course of this Agreement through such date, weighted by the amount of

Adjustment” means the adjustment to the tax basis of an Adjustable Asset
under any provision of the Code, including Section 732 of the Code (in
situations where, as a result of one or more Exchanges, CPE LLC becomes an

of the Code, or Sections 743(b) and 754 of the Code (in situations where,
following an Exchange, CPE LLC remains in existence as an entity for tax
purposes) as a result, in each case, of an Exchange, the Distribution, and/or payments
made 

 

2

 

pursuant to this Agreement. For the avoidance of doubt, payments made
under this Agreement shall not be treated as resulting in a Basis Adjustment to
the extent that such payments are treated as Imputed Interest. Notwithstanding
any other provision of this Agreement, the amount of any Basis Adjustment
resulting from an Exchange of one or more RTEA Units shall be determined
without regard to any Pre-Exchange Transfer of such RTEA Units and as if any
such Pre-Exchange Transfer had not occurred.

Day” means Monday through Friday of each week, except that a legal holiday
recognized as such by the government of the United States of America or the

series of related transactions or open market purchases or tenders in which
more than 50% of such entity’s general voting power is transferred to or
acquired by any other Person or Group, or (3) the sale or transfer by such
entity of all or substantially all of its assets; provided, however, that, in determining whether a Change of
Control of Buyer or CPE LLC has occurred, common stock of Buyer and RTEA Units (A) acquired
pursuant to the exercise by RTEA of its redemption right (including such an
exercise in which Buyer exercises the Buyer Assumption Right) or (B) transferred
to any Affiliate of RTEA or (C) transferred by RTEA shall not constitute
an event which could cause a Change of Control.

Freeze Date (including any such changes that are not scheduled to take effect
until after the Freeze Date); (ii) incorporating the assumption that all
non-amortizable, non-depletable, non-depreciable Adjustable Assets will be
deemed to be disposed of, at a price equal to their tax basis, on the later of
the Freeze Date and the fifteenth anniversary of the date of the Initial Sale
and (iii) if a carryback from a Taxable Year gives rise to a refund with
respect to a prior Taxable Year, such refund shall, for purposes of computing
payments required to be made pursuant to this Agreement, be treated as an
offset to the tax liability for the Taxable Year in which the carryback arises
(and if the refund exceeds such tax liability, a negative tax liability for
such year) and not as an adjustment to the tax liability of the prior Taxable
Year.  For the avoidance of doubt, if, in
any year projected, there is calculated to be a greater actual tax liability
than hypothetical tax liability (or if both actual and hypothetical tax
liabilities are negative, a lesser negative actual tax liability than negative
hypothetical tax liability), then pursuant to Sections 4.03(b)(i) and
4.04(c)(iii), the Projected Tax Benefit Schedule shall show a payment due from
RTEA to CPE of zero for such projected year. 
Further, in the case of an early termination, the Projected Tax Benefit
Schedule: (i) shall treat all RTEA Units that have not yet been Exchanged as
being Exchanged on the Early Termination Notice Date for the cash purchase
price Buyer would have paid under the Buyer Assumption Right had such Exchange
actually occurred on the Early Termination Notice Date; (ii) shall
subtract from each taxable year for which the model predicts a payment an
amount equal to the Assumed Administrative Cost; and (iii) shall not
reflect any adjustments for inflation with respect to any factual input.

 

“Realized
Tax Benefit” means, for a Taxable Year, the excess, if any, of the
Hypothetical Buyer Tax Liability over the Actual Buyer Tax Liability. If all or
a portion of the Actual Buyer Tax Liability for the Taxable Year arises as a
result of a Buyer Audit, such liability shall not be included in determining
the Realized Tax Benefit unless and until there has been a Determination.

 

“Realized
Tax Detriment” means, for a Taxable Year, the excess, if any, of the Actual
Buyer Tax Liability over the Hypothetical Buyer Tax Liability. If all or a
portion of the Actual Buyer Tax Liability for the Taxable Year arises as a
result of a Buyer Audit, such liability shall not be included in determining
the Realized Tax Detriment unless and until there has been a Determination.

1.446-1(c)(1)(ii) and Treasury Regulation 1.461-1(a)(2) as of the
date of this Agreement, and which are added to the tax basis of the Adjustable
Assets when they are paid or otherwise meet the all events and economic
performance tests (see Treasury Regulation 1.461-4). For this purpose, the
obligation assumed by the Buyer or CPE LLC for the closure of the mines is
assumed to meet the all events and economic performance tests when the mines
are closed. The current cost to reclaim acreage disturbed as of the transaction
date is assumed to meet the all events and economic performance tests as those

LLC, directly or indirectly, wholly or partly through any entity that is
treated as a corporation for U.S. federal income tax purposes.  For the avoidance of doubt, (i) the
granting of any lien on any Adjustable Asset or the pledging of any Adjustable
Asset shall not constitute a Restricted Transfer so long as such pledge or lien
is permitted under the terms of the CPE LLC Agreement; and (ii) a transfer
to any entity owned directly or indirectly in part by Cloud Peak Energy
Services, Inc. (“CPESC”) shall not constitute a Restricted Transfer so
long as CPESC holds (taking into account both direct and indirect interests),
less than a 1% interest in the capital of such entity and less than a 1%
interest in the profits and losses (and each item thereof) of such entity.

“Taxable
Year” means a taxable year as defined in Section 441(b) of the

Rate as a discount rate and assuming for purposes of computing such future (or
present) values that the Actual/Modified Payment Difference with respect to
Taxes for each Taxable Year accrues on the due date (without extensions) for
filing the U.S. federal income tax return of Buyer with respect to such Taxable
Year; or

of the Actual/Modified Payment Differences for all Taxable Years ending on or
before the Change of Control Date but on or after the most recent Exchange

ARTICLE II

DETERMINATION OF
EXCHANGE BASIS SCHEDULE AND REALIZED TAX BENEFIT

 

Section 2.01.                       Basis Adjustment.  Buyer and
RTEA acknowledge that, as a result of an Exchange, Buyer’s tax basis in the
applicable Adjustable Assets shall be adjusted to reflect a Basis Adjustment,
if any.  The parties hereby acknowledge
that, generally, Buyer’s tax basis in the applicable Adjustable Assets shall be
increased by the excess, if any, of (i) the sum of (x) the amount of
cash or other consideration transferred to RTEA, its Affiliate, or any direct
or indirect successor pursuant to the Exchange as payment for the redeemed or
transferred RTEA Units (including the fair market value of any Buyer common
stock, if applicable), plus (y) the amount of payments made pursuant to
this Agreement with respect to such Exchange plus (z) the amount of debt
allocated to the RTEA Units acquired pursuant to such Exchange over (ii) RTEA’s
(or its Affiliate’s) share of the tax basis of the Adjustable Assets immediately
prior to the Exchange attributable to the RTEA Units Exchanged.

 

9

 

Section 2.02.        Duff &
Phelps Schedule.  Within 30 calendar
days after any Exchange Date, Buyer shall cause Duff & Phelps LLC, or
another Person that has nationally recognized expertise in valuation matters
and that is acceptable to both RTEA and Buyer, to prepare and deliver to Buyer
and RTEA a schedule (the “Duff & Phelps Schedule”) that
allocates the purchase price of the RTEA Units being acquired by CPE or
redeemed by CPE LLC in such Exchange among the various assets that CPE LLC
owns, directly and indirectly.  Buyer and
RTEA shall agree on the methodology to be used in the preparation of the Duff &
Phelps Schedule with respect to the Initial Sale (the “Initial Duff &
Phelps Schedule”).  The Duff &
Phelps Schedule with respect to all subsequent Exchanges shall be prepared in a
manner that is consistent with the methodology used to produce the Initial Duff &
Phelps Schedule.  If Buyer and RTEA
cannot agree as to whether a Duff & Phelps Schedule was produced
consistently with the methodology used to produce the Initial Duff &
Phelps Schedule within 60 days after an Exchange, the parties shall employ the
Reconciliation Procedures.

 

Section 2.03.        Exchange
Basis Schedule.  Within 45 calendar
days after Buyer and RTEA receive the Duff & Phelps Schedule, a
schedule (the “Exchange Basis Schedule”) shall be produced that shall
show, for purposes of Taxes, (i) the actual unadjusted tax basis of the
Adjustable Assets as of each applicable Exchange Date, (ii) the amount by
which each Adjustable Asset’s tax basis is reduced pursuant to the Deferred
Basis Reduction, (iii) the Basis Adjustment with respect to the Adjustable
Assets as a result of the Exchange, (iv) the Irreducible Basis Amount with
respect to the Exchange, (v) the period or periods, if any, over which the
Adjustable Assets are amortizable and/or depreciable, and (vi) the period
or periods, if any, over which each Basis Adjustment is amortizable and/or
depreciable.  The Exchange Basis Schedule
shall be prepared in accordance with the information and assumptions contained
in the Duff & Phelps Schedule, as well as Sections 743 and 755 of the
Code, the Treasury Regulations thereunder, and any similar provisions of Tax
Law, as appropriate.  RTEA shall prepare
the Exchange Basis Schedule with respect to the Initial Sale, and Buyer shall
prepare the Exchange Basis Schedule with respect to each subsequent Exchange.

 

Section 2.04.        Tax
Benefit Schedule.  Within the later
of 45 calendar days after the filing of the U.S. federal income tax return of
Buyer for any Taxable Year and 15 calendar days after the receipt by Buyer of
the last Exchange Basis Schedule with respect to any Taxable Year, Buyer shall
provide to RTEA (i) a schedule showing the calculation of the Realized Tax
Benefit or Realized Tax Detriment for such Taxable Year (a “Tax Benefit
Schedule”); (ii) a certification signed by the CFO of Buyer stating
that the Tax Benefit Schedule is consistent with the Tax Returns of Buyer and
each of its Subsidiaries, and that the Tax Benefit Schedule was prepared using
the same standard of care as the Tax Returns of Buyer and each of its
Subsidiaries; and (iii) a calculation of the Tax Benefit Payment due with
respect to such Taxable Year, if any, with an estimate of the Interest Amount
based on the expected payment date (a “Tax Benefit Computation Schedule”).
The Tax Benefit Schedule and Tax Benefit Computation Schedule will become final
as provided in Section 2.05(a) and may be amended as provided in Section 2.05(b) (subject
to the procedures set forth in Section 2.05(b)).

 

Section 2.05.        Procedures,
Amendments.

 

(a)     Procedure.  Every time Buyer delivers to RTEA a Tax
Benefit Schedule or an Amended Schedule pursuant to Section 2.05(b), Buyer
shall also (x) deliver to RTEA schedules and work papers providing
reasonable detail regarding the preparation of such Schedule and (y) allow
RTEA reasonable access, at no cost to RTEA, to the appropriate representatives
at Buyer, or any Affiliate of Buyer, in connection with a review of such
Schedule. Buyer shall also allow RTEA reasonable access to third parties
retained by Buyer or its Affiliates, and the costs of RTEA’s access to such
third parties shall be borne 85% by RTEA and 15% by Buyer.  Any Schedule received by RTEA shall become
final and binding on all parties unless RTEA, within 30 calendar days after
receiving such Schedule, provides Buyer with notice of a reasonable objection
to such Schedule (“Objection Notice”) made in good faith. If the
parties, for any reason, are unable to successfully resolve the issues raised
in such notice within 30 calendar days of receipt by Buyer of an Objection
Notice, Buyer and RTEA shall employ the Reconciliation Procedures.

 

(b)     Amended
Schedule.  Any Exchange Basis
Schedule (or amended Exchange Basis Schedule) or applicable Tax Benefit
Schedule (or amended Tax Benefit Schedule) and its corresponding Tax Benefit
Computation Schedule for any Taxable Year shall be amended from time to time by
Buyer (such Schedule, an “Amended Schedule”) (i) in connection with
a Determination affecting such Schedule, (ii) to correct inaccuracies in
the Schedule identified as a result of the receipt of additional factual
information relating to a Taxable Year after the date the Schedule was provided
to RTEA, (iii) to comply with the Expert’s determination under the Reconciliation

 

10

 

Procedures, (iv) to reflect a change in the
Realized Tax Benefit or Realized Tax Detriment for such Taxable Year
attributable to a carryback or carryforward of a loss or other tax item to such
Taxable Year, or (v) to reflect a change in the Realized Tax Benefit or
Realized Tax Detriment for such Taxable Year attributable to an amended Tax
Return filed for such Taxable Year or pursuant to a Determination for such
Taxable Year. Upon the amendment of any Exchange Basis Schedule (or amended
Exchange Basis Schedule) or any Tax Benefit Schedule (or amended Tax Benefit
Schedule), the corresponding Duff & Phelps Schedule (or amended Duff &
Phelps Schedule) shall be amended in a consistent manner.

 

Section 2.06.        Costs
and Expenses.  All reasonable
third-party out of pocket costs and expenses incurred by RTEA and Buyer to
produce, evaluate, or resolve any disagreement with respect to the Duff &
Phelps Schedule, the Life of Mine Model, the Projected Tax Benefit Schedule, or
any Schedule required to be produced under this Agreement that would not have
been incurred by RTEA or Buyer, respectively, if RTEA and Buyer had not entered
into this Agreement, shall be borne 85% by RTEA and 15% by Buyer unless otherwise
explicitly provided under this Agreement. 
For the avoidance of doubt, such costs or expenses shall not include
time or resources spent by employees of RTEA, Buyer, or any of their respective
Affiliates.

 

ARTICLE III

TAX BENEFIT PAYMENTS

 

Section 3.01.        Payments.

 

(a)     Payments.  Within five (5) calendar days of a Tax
Benefit Schedule and the corresponding Tax Benefit Computation Schedule
delivered to RTEA becoming final in accordance with Section 2.05(a), Buyer
shall pay to RTEA the Tax Benefit Payment (if the Tax Benefit Payment is a
positive number) or RTEA shall pay to Buyer the Tax Benefit Payment (if the Tax
Benefit Payment is a negative number) for such Taxable Year, determined
pursuant to Section 3.01(b). Each such Tax Benefit Payment shall be made
by wire transfer of immediately available funds to a bank account of RTEA
previously designated by RTEA to Buyer, to a bank account of Buyer previously
designated by Buyer to RTEA, or as otherwise agreed by Buyer and RTEA. For the
avoidance of doubt, no Tax Benefit Payment shall be made in respect of
estimated tax payments and no Tax Benefit Payment shall be made in respect of
an Amended Schedule except in accordance with Section 3.01(b). At the same
time that the Tax Benefit Payment is paid, the payor shall provide
documentation to the recipient illustrating the payor’s calculation of the
Interest Amount with respect to such Tax Benefit Payment.

 

(b)     A “Tax
Benefit Payment” with respect to a Taxable Year means an amount equal to
85% of the sum of the Net Tax Benefit and the Interest Amount for that Taxable
Year. The “Net Tax Benefit” for each Taxable Year shall be an amount
equal to the difference of (i) the Cumulative Net Realized Tax Benefit for
such Taxable Year and (ii) the total amount of net payments previously
made from Buyer to RTEA under this Section 3.01, excluding all payments
attributable to Interest Amount (the “Net Benefits Already Paid”).  The “Interest Amount” for each Taxable
Year shall equal the interest on the Net Tax Benefit for such Taxable Year
calculated at the Agreed Rate, compounded monthly, from the due date (without
extensions) for filing the U.S. federal income tax return of Buyer with respect
to Taxes for such Taxable Year until the Payment Date.  For the avoidance of doubt, each of the Net
Tax Benefit, the Interest Amount, and the Tax Benefit Payment with respect to a
given Taxable Year may be a negative number. 
Notwithstanding any other provisions of this Agreement, distributions
and payments made pursuant to Section 5.4(f) of the CPE LLC Agreement
shall not be taken into account in calculating amounts due under this Section 3.01
or any other provision of this Agreement.

 

(c)     Upon
delivery of an Exchange Basis Schedule as described in Section 2.03, Buyer
shall pay to RTEA an amount equal to the Irreducible Basis Amount Payment, if
any.

 

(d)     Within
ten (10) calendar days of December 31, March 31, June 30,
and September 30 of each year, Buyer shall pay to RTEA an amount equal to
the product of (i) the Notional Loan Balance as of the first day of the
quarter ending on such date and (ii) the Notional Interest Rate.

 

Section 3.02.        No
Duplicative Payments.  It is intended
that the above provisions of this Agreement will not result in duplicative
payment of any amount (including interest) required under this Agreement. It is
also 

 

11

 

intended that the
provisions of this Agreement provide that Buyer shall pay to RTEA 85% of the
Cumulative Net Realized Tax Benefit and Interest Amount and that RTEA pay to
Buyer any excess over 85% of the Cumulative Net Realized Tax Benefit and
Interest Amount that RTEA may have received. The provisions of this Agreement
shall be construed in the appropriate manner in order to realize such
intentions.

 

ARTICLE IV

TERMINATION AND CHANGE
OF CONTROL

 

Section 4.01.        Early
Termination and Breach of Agreement.

 

(a)     Subject
to Section 4.03, Buyer may terminate this Agreement at any time by paying
to RTEA the Early Termination Payment after the Early Termination Payment Date;
provided, however, that this Agreement shall only terminate upon the receipt of
the Early Termination Payment, and provided, further, that Buyer may withdraw
any notice to execute its termination rights under this Section 4.01(a) prior
to the Early Termination Payment Date. Upon payment of the Early Termination
Payment by Buyer, neither RTEA nor Buyer shall have any further payment
obligations under this Agreement, other than for any unpaid Tax Benefit Payment
with respect Taxable Years ending on or before the Early Termination Notice
Date.

 

(b)     In the
event that Buyer materially breaches this Agreement, whether as a result of
failure to make any payment when due, failure to honor any other material
obligation required hereunder (including the provisions of Section 4.04(a)(2)),
by operation of law as a result of the rejection of this Agreement in a case
commenced under the Bankruptcy Code, or otherwise, then all of Buyer’s
obligations hereunder shall be accelerated and such obligations shall be calculated
as if an Early Termination Notice had been delivered on the date of such breach
and shall include, but not be limited to, (1) the Early Termination
Payment calculated as if an Early Termination Notice had been delivered on the
date of a breach, and (2) any Tax Benefit Payment due and payable but
unpaid as of the date of a breach. Notwithstanding the foregoing, in the event
that Buyer materially breaches this Agreement, RTEA shall be entitled to elect
to receive the amounts set forth in (1) and (2) above or to seek
specific performance of the terms hereof. The parties agree that the failure to
make any payment due pursuant to this Agreement within 45 calendar days of the
date such payment is due shall be deemed to be a material breach under this
Agreement for all purposes of this Agreement, and that it will not be
considered to be a breach of a material obligation under this Agreement to make
a payment due pursuant to this Agreement within 45 calendar days of the date
such payment is due.  Buyer and RTEA
specifically agree that the remedies provided in this Section are not
intended as a penalty.

 

(c)     Buyer and
RTEA agree that the aggregate fair market value of the Tax Benefit Payments
cannot be ascertained with any reasonable certainty for U.S. federal income tax
purposes.

 

Section 4.02.        Early
Termination Notice.  If Buyer chooses
to exercise its right of early termination under Section 4.01 above, Buyer
shall deliver to RTEA notice of such intention to exercise such right (“Early
Termination Notice”) together with a schedule (the “Early Termination
Schedule”) showing, in reasonable detail, the calculation of the Early
Termination Payment. The applicable Early Termination Schedule shall become
final and binding on all parties unless RTEA, within 30 calendar days after
receiving the Early Termination Schedule, provides Buyer with notice of a
reasonable objection to such Early Termination Schedule made in good faith (“Early
Termination Objection Notice”). If the parties, for any reason, are unable
to successfully resolve the issues raised in such notice within 30 calendar
days after receipt by Buyer of the Early Termination Objection Notice, Buyer
and RTEA shall employ the Reconciliation Procedures.  If RTEA provides an Early Termination
Objection Notice objection, the Early Termination Schedule shall become final
upon the earlier of an agreement between the parties or the resolution of a
Reconciliation Dispute pursuant to Section 7.09.

 

Section 4.03.        Payment
upon Early Termination.

 

(a)     Date
Payment Due.  Within three calendar
days after agreement between RTEA and Buyer with respect to the Early
Termination Schedule, Buyer shall pay to RTEA an amount equal to the Early
Termination Payment.  Such payment shall
be made by wire transfer of immediately available funds to a bank account
designated by RTEA or as otherwise agreed by Buyer and RTEA.  Failure by Buyer to pay the Early Termination
Payment pursuant to this Section 4.03 shall in no event be treated as a
material breach of this Agreement but the Early 

 

12

 

Termination Notice and the Early Termination Schedule
finalized pursuant to Section 4.02 given with respect to such notice shall
be void.

 

(b)     Early
Termination Payment.  The “Early
Termination Payment” shall equal the excess, if any, of (i) the sum of
(x) the present value, as of the Early Termination Payment Date, of all
payments that the Projected Tax Benefit Schedule as of the Early Termination
Notice Date provides that RTEA should receive from Buyer with respect to all
Taxable Years ending after the Early Termination Notice Date and that are due
after the Early Termination Payment Date and (y) the future value, as of
the Early Termination Payment Date, of all payments that the Projected Tax
Benefit Schedule as of the Early Termination Notice Date provides that RTEA
should receive from Buyer with respect to all Taxable Years ending after the
Early Termination Notice Date and that are due before the Early Termination
Payment Date, in both cases using the Early Termination Rate as a discount rate
(or interest rate), over (ii) the Total Actual/Modified Payment Difference
as of the Early Termination Notice Date. For purposes of computing such present
value (or future value), any payment that the Projected Tax Benefit Schedule
provides that RTEA should receive from Buyer with respect to Taxes of a Taxable
Year shall be treated as payable on the due date (without extensions) for
filing the U.S. federal income tax return of Buyer with respect to such Taxes
for such Taxable Year.  For the avoidance
of doubt, a negative Total Actual/Modified Payment Difference shall be added to
the amount calculated in clause (i) of this Section 4.03(b).

 

Section 4.04.        Transfers
of Assets, Change of Control, Change of Structure.

 

(a)     Transfers
of Assets.  The provisions of this
section 4.04(a) shall apply to any transfer that is deemed to occur for
U.S. federal income tax purposes, including any transfer that is deemed to
occur under the provisions of Treasury Regulation 301.7701-3.

 

(1)  Generally.  Buyer shall
give RTEA at least 30 days’ written notice prior to any Non-Exempted Transfer.

 

(2)  Restricted Transfers. 
Buyer shall not, and shall not cause any of its Subsidiaries to,
transfer any Adjustable Assets in a Restricted Transfer.

 

(3)  Asset Transfers.  If
Buyer, or a Subsidiary of Buyer, transfers any Adjustable Assets in a
Non-Exempted Transfer that is not currently fully taxable for U.S. federal
income tax purposes, then, for purposes of that Taxable Year and all subsequent
Taxable Years, if the Alternative Tax Benefit Payment calculated with respect
to such Adjustable Assets for a Taxable Year is larger than the Tax Benefit
Payment for that Taxable Year, Section 3.01 shall be applied to such
Taxable Year as if all references to the Tax Benefit Payment were instead
references to the Alternative Tax Benefit Payment calculated with respect to
such Adjustable Assets, but leaving the Net Benefits Already Paid
unchanged.  If the foregoing sentence
cannot be applied because Buyer is not able to calculate either the Tax Benefit
Payment or the Alternative Tax Benefit Payment with respect to such Adjustable
Assets for a relevant Taxable Year (the “Incalculable Year”), then for
purposes of applying Section 3.01 to the Incalculable Year and all
subsequent Taxable Years, (i) Buyer or such Subsidiary shall be treated as
having disposed of such Adjustable Asset in a fully taxable transaction on the
first day of the Incalculable Year and (ii) the consideration deemed to be
received by Buyer or such Subsidiary shall be equal to the gross fair market
value of such Adjustable Asset.  For the
avoidance of doubt, each Non-Exempted Transfer of an Adjustable Asset will be
subject to this Section 4.04(a)(3) to the extent that it is not
currently taxable and to Section 4.04(a)(4) to the extent that it is
currently taxable.

 

(4)  Increases to Notional Loan Balance.  If Buyer, or a Subsidiary of Buyer, transfers
any Adjustable Asset with a gross value greater than $10 million in a transfer
that is taxable in whole or in part and is made outside the ordinary course of
business, the Notional Loan Balance shall be increased on such date by an
amount equal to the product of (i) the taxable gain (excluding any gain
attributable to any increase in the fair market value between the date of such
transfer and the most recent Exchange Date) allocated to RTEA with respect to
such transfer (the “Accelerated RTEA Gain” with respect to such
transaction) and (ii) the Maximum RTEA Tax Rate.  Following any such transaction, Buyer shall
promptly (but in no case more than forty-five (45) days following the date of
the transaction) compute the increased Notional Loan Balance and provide RTEA
with written notice thereof.  For the
avoidance of doubt, each Non-Exempted Transfer of an Adjustable Asset will be
subject to Section

 

13

 

4.04(a)(3) to
the extent that it is not currently taxable and to this Section 4.04(a)(4) to
the extent that it is currently taxable.

 

(5)  Decreases to Notional Loan Balance.  Upon each Exchange Date, the Notional Loan
Balance shall be reduced by the Notional Loan Repayment Amount.  Following any such transaction, Buyer shall
promptly (but in no case more than forty-five (45) days following the date of
the transaction) compute the decreased Notional Loan Balance and provide RTEA
with written notice thereof.

 

(b)     Change
of Control of Subsidiary of Buyer. 
If there is a Change of Control with respect to any Subsidiary of Buyer,
other than CPE LLC, in any Taxable Year (other than as a result of a Change of
Control of Buyer or CPE LLC), such Subsidiary shall be treated as having
disposed of all of its Adjustable Assets immediately before such Change of
Control in transactions that are taxable to the same extent that the
disposition of the Subsidiary is taxable, and the provisions of Section 4.04(a) shall
apply to such deemed dispositions.

 

(c)     Change
of Control of Buyer or of CPE LLC. 
In the event of a Change of Control of Buyer or CPE LLC, with respect to
the Taxable Year of such Change of Control and subsequent Taxable Years, (i) no
payments will be due under Section 3.01(a) with respect to Taxable
Years ending after the Change of Control Date; (ii) Buyer or, if
applicable, its successor (Buyer or such entity, as appropriate, the “Surviving
Entity”) shall not be obligated to make any payments under Section 3.01(c);
and (iii) the Surviving Entity shall be obligated to make payments to RTEA
in the amounts and on the dates provided in the Projected Tax Benefit Schedule
with respect to Taxable Years ending after such Change of Control Date, except
that each such payment shall be multiplied by the Change of Control Payment
Modifier as of such Change of Control Date. 
Notwithstanding the foregoing, if RTEA owns RTEA Units or common stock
of the Surviving Entity 180 calendar days after the Change of Control of Buyer
or CPE LLC, this Agreement shall continue as if there had been no Change of
Control of Buyer or CPE LLC, as applicable. 
In the event that, after such Change of Control, the credit rating of
the Surviving Entity is lower than Buyer’s credit rating prior to the events
giving rise to the Change of Control, and this Agreement has not been
terminated by the Surviving Entity exercising its right to terminate this
Agreement pursuant to Section 4.01(a), the Surviving Entity shall obtain
credit support (which credit support may consist of a pledge of its assets to
RTEA to secure payments under this Agreement) sufficient to cause the remaining
payments under this Agreement to have a credit rating at least as high as the
rating on the most subordinated outstanding bona fide debt of CPE LLC prior to
the events giving rise to the Change of Control.  In the event of a dispute arising under this Section 4.04(c),
Buyer and RTEA shall employ the Reconciliation Procedures.  In the event of a Change of Control, all
references to Buyer herein shall be read as references to the Surviving Entity.

 

(d)     Change
of Structure.  If Buyer changes the
structure of CPE LLC or its interest therein in a manner that diminishes the
benefits allocable to RTEA under this Agreement (a “Change of Structure”),
including, without limitation, a sale of Adjustable Assets to a Subsidiary that
is treated as a corporation for U.S. federal income tax purposes, then, notwithstanding
anything to the contrary herein, the calculation of the payments to be made to
RTEA pursuant to this Agreement shall be made as if no such Change of Structure
had occurred.

 

ARTICLE V

LATE PAYMENTS

 

Section 5.01.        Late
Payments.  The amount of all or any
portion of any payment or advance not made when due under the terms of this
Agreement, including any Tax Benefit Payment not made to RTEA or Buyer, shall
be payable together with any interest thereon, computed at the Default Rate,
compounded monthly, and commencing from the date on which such payment was due
and payable; provided, that such additional interest shall not be deemed
liquidated damages and the party that is owed payment shall retain its remedies
hereunder.

 

ARTICLE VI

PARTICIPATION;
CONSISTENCY; COOPERATION

 

Section 6.01.        Participation
in Buyer’s Tax Matters.  Except as
otherwise provided herein, Buyer shall have full responsibility for, and sole
discretion over, all tax matters concerning Buyer and its Subsidiaries,
including, 

 

14

 

without
limitation, the preparation, filing or amending of any U.S. federal, state, or
local or non-U.S. tax return and the defending of any issues pertaining to
taxes, subject to a requirement that Buyer act in good faith in connection with
its control of any matter which is reasonably expected to affect RTEA’s rights
and obligations under this Agreement. Further, the Buyer shall promptly notify
RTEA in writing of and keep RTEA reasonably informed with respect to the
portion of any Buyer Audit the outcome of which is reasonably expected to
affect RTEA’s rights and obligations under this Agreement, and shall provide
RTEA reasonable opportunity to provide information and other input to Buyer,
its Subsidiaries, any consolidated group of which Buyer is a member, and their
respective advisors concerning the conduct of any such portion of such Buyer
Audit. RTEA shall have the right to attend in person or by telephone (but not
participate in) any Buyer Audit the outcome of which could reasonably be
expected to affect the amount of net payments that RTEA is expected to receive
under this Agreement by $10 million. 
Buyer shall not settle or fail to contest any issue pertaining to taxes
that is reasonably expected to affect RTEA’s rights and obligations under this
Agreement without RTEA’s consent, such consent not to be unreasonably withheld.

 

Section 6.02.        Consistency.  Unless there has previously been a
Determination to the contrary, RTEA, Buyer, and Buyer’s Subsidiaries agree to
report and cause to be reported for all purposes, including U.S. federal,
state, local and foreign tax purposes and financial reporting purposes, all
tax-related items, in a manner consistent with this Agreement, including,
without limitation, (1) any allocation shown on any Exchange Basis
Schedule, (2) the Section 754 Elections made with respect to any
applicable Subsidiaries of Buyer (including that each such election was validly
and timely made, whether or not the electing entity was a Subsidiary of Buyer
at the time of such election), and (3) the treatment of any payment made
pursuant to Section 3 or Section 4 of this Agreement.  Furthermore, the parties agree to treat any
payment made pursuant to Section 3 or Section 4 or this Agreement, other
than payments of Imputed Interest, as an adjustment to the purchase price of
the RTEA Units acquired in an Exchange.

 

Section 6.03.        Cooperation.  (a) Each of RTEA and Buyer shall (1) furnish
to the other party in a timely manner such information, documents and other
materials as the other party may reasonably request for purposes of making any
determination or computation necessary or appropriate under this Agreement,
preparing any financial statement, preparing any tax return or contesting or
defending any audit, examination or controversy with any Taxing Authority, (2) make
itself available to the other party and its representatives to provide
explanations of documents and materials and such other information as the other
party or its representatives may reasonably request in connection with any of
the matters described in clause (1) above, and (3) reasonably
cooperate in connection with any such matter.

 

(b)     RTEA and
Buyer will promptly provide to the other a copy of any written communication
from or with the IRS or any other Taxing Authority that relates in any respect
to this Agreement or to the treatment of any Exchange or related transaction
(including any communication that relates to the allocation shown on any
Exchange Basis Schedule).

 

Section 6.04.        Section 754
Elections.  If, at any point, any
Subsidiary of Buyer that is a Partnership does not have a Section 754
Election in effect, Buyer shall cause such Subsidiary of Buyer to make a valid Section 754
Election at the time that such Subsidiary files its Tax Return for such Taxable
Year.

Section 7.02.        Counterparts.  This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each
of the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart. Delivery of an executed signature page to
this Agreement by facsimile transmission shall be as effective as delivery of a
manually signed counterpart of this Agreement.

 

Section 7.03.        Entire
Agreement; No Third Party Beneficiaries. 
This Agreement constitutes the entire agreement and supersedes all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof. This Agreement shall be binding upon and
inure solely to the benefit of each party hereto and their respective
successors and permitted assigns, and nothing in this Agreement, express or
implied, is intended to or shall confer upon any other Person any right,
benefit or remedy of any nature whatsoever under or by reason of this
Agreement.

 

Section 7.04.        Governing
Law.  (a) This Agreement is to
be construed in accordance with and governed by the internal laws of the State
of New York without giving effect to any choice of law rule that would
cause the application of the laws of any jurisdiction other than the internal
laws of the State of New York to the rights and duties of the Parties.

 

(b)         Each party
hereby irrevocably and unconditionally consents to submit to the sole and
exclusive jurisdiction of the United States District Court for the Southern
District of New York or, if such court does not have subject matter
jurisdiction, the Supreme Court of the State of New York sitting in New York
County (the “New York Courts”) for any legal action or other legal
proceeding arising out of or relating to this Agreement, or the negotiation,
validity or performance of this Agreement, or the transactions contemplated
thereby (and agrees not to commence any legal action or other legal proceeding
relating thereto except in such courts). 
Furthermore, each party:

 

(i)            expressly
and irrevocably consents and submits to the jurisdiction of the New York Courts
in connection with any such legal proceeding, including to enforce any
settlement, order or award;

 

16

 

(ii)           consents
to service of process in any such proceeding in any manner permitted by the
laws of the State of New York, and also agrees that service of process by
registered or certified mail, return receipt requested, at its address
specified pursuant to Section 7.01 is sufficient and reasonably calculated
to give actual notice;

 

(iii)          agrees
that the New York Courts shall be deemed to be a convenient forum; and

 

(iv)          waives
and agrees not to assert (by way of motion, as a defense or otherwise), in any
such legal proceeding commenced in the New York Courts that such party is not
subject personally to the jurisdiction of such court, that such legal
proceeding has been brought in an inconvenient forum, that the venue of such
proceeding is improper or that this Agreement or the subject matter hereof or
thereof may not be enforced in or by such court; and

 

(c)         Except
as otherwise set forth in Section 7.09, in the event of any action or
other proceeding relating to this Agreement or the enforcement of any provision
of this Agreement, the prevailing party (as determined by the court) shall be
entitled to payment by the non-prevailing party of all costs and expenses
(including reasonable attorneys’ fees) incurred by the prevailing party,
including any costs and expenses incurred in connection with any challenge to
the jurisdiction or the convenience or propriety of venue of proceedings before
the New York Courts.

 

(d)     Each of
the parties hereto hereby waives to the fullest extent permitted by applicable
Law any right it may have to a trial by jury with respect to any legal action
or other legal proceeding directly or indirectly arising out of, under or in
connection with this Agreement.  Each of
the parties hereto (i) 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 that foregoing
waiver and (ii) acknowledges that it and the other parties hereto have
been induced to enter into this Agreement and the transactions contemplated by
this Agreement, as applicable, by, among other things, the mutual waivers set
forth in this Section 7.04(d).

 

Section 7.05.        Severability.  If any terms or other provision of this
Agreement shall be determined by a court, administrative agency or arbitrator
to be invalid, illegal or unenforceable, such invalidity, illegality or
unenforceability shall not render the entire Agreement invalid. Rather, this
Agreement shall be construed as if not containing the particular invalid,
illegal or unenforceable provision, and all other provisions of this Agreement
shall nevertheless remain in full force and effect so long as the economic or
legal substance of the transactions contemplated hereby is not affected in any
manner materially adverse to either party. Upon such determination that any
term or other provision is invalid, illegal or unenforceable, the parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in an acceptable manner to the end
that the transactions contemplated hereby are fulfilled to the fullest extent
permitted under applicable Law.

 

Section 7.06.        Successors;
Assignment; Amendments; Waivers.

 

(a)     RTEA may
assign its rights and obligations under this Agreement without the prior
written consent of Buyer and may pledge or assign its rights under this
Agreement in connection with a financing and the enforcement of the lender’s
rights thereunder.  Notwithstanding the
foregoing, if RTEA assigns its rights and obligations under this Agreement to
any Person that is not an Affiliate of RTEA, such assignee shall not have the
right to attend certain Buyer Audits that Section 6.01 provides to RTEA;
however, a nationally recognized accounting or law firm retained by such
assignee shall have the same right to attend Buyer Audits that Section 6.01
provides to RTEA.

 

(b)     This
Agreement may only be amended in a writing signed by both Buyer and RTEA. No
provision of this Agreement may be waived unless such waiver is in writing and
signed by the party against whom the waiver is to be effective.

 

(c)     All of
the terms and provisions of this Agreement shall be binding upon, shall inure
to the benefit of and shall be enforceable by the parties hereto and their
respective successors and permitted assigns. Buyer shall, by written agreement,
require and cause any direct or indirect successor to all or substantially all
of the Adjustable Assets or the business or assets of Buyer (whether by
purchase, merger, consolidation or otherwise) expressly to

 

17

 

assume and agree to perform this Agreement in the same
manner and to the same extent that Buyer would be required to perform if no
such succession had taken place.  If
Buyer does not acquire such a written agreement and present it to RTEA before
such direct or indirect successor of Buyer succeeds to all or substantially all
of the Adjustable Assets or the business or assets of Buyer, the Surviving
Entity shall become obligated to immediately pay to RTEA an amount equal to the
present value of all future payments owed to RTEA under this Agreement,
discounted at the Early Termination Rate.

 

Section 7.07.        Titles
and Subtitles.  The titles of the
sections and subsections of this Agreement are for convenience of reference
only and are not to be considered in construing this Agreement.

 

Section 7.08.        Resolution
of Disputes.  Other than those
disputes that are subject to Section 7.09, any and all disputes arising
out of or relating to this Agreement (including any claim of fraud,
misrepresenation or fraudulent inducement or any question of validity or
effectof this Agreement) shall be resolved in accordance with Section 9.10
of the Master Separation Agreement.

 

Section 7.09.        Reconciliation.  In the event that Buyer and RTEA are unable
to resolve a disagreement with respect to the matters governed by Sections
2.01, 2.02, 2.03, 2.04, 2.05, 4.02, and 4.04 within the relevant period
designated in this Agreement (“Reconciliation Dispute”), the
Reconciliation Dispute shall be submitted for determination to a nationally
recognized expert (the “Expert”) in the particular area of disagreement
mutually acceptable to both parties. The Expert shall be a partner in a
nationally recognized accounting firm or law firm, and the Expert shall not,
and the firm that employs the Expert shall not, have any material relationship
with Buyer, RTEA or other actual or potential conflict of interest. If the
parties are unable to agree on an Expert within fifteen (15) calendar days
of receipt by the respondent(s) of written notice of a Reconciliation
Dispute, the Expert shall be appointed by JAMS (formerly Judicial Aribtration
and Mediation Services, Inc.). The Expert shall resolve any matter
relating to an Exchange Basis Schedule or an amendment thereto or the Early
Termination Schedule or an amendment thereto within 30 calendar days and shall
resolve any matter relating to a Tax Benefit Schedule or an amendment thereto
within 15 calendar days or as soon thereafter as is reasonably practicable, in
each case after the matter has been submitted to the Expert for resolution.
Notwithstanding the preceding sentence, if the matter is not resolved before
any payment that is the subject of a disagreement is due or any Tax Return
reflecting the subject of a disagreement is due, such payment shall be made on
the date prescribed by this Agreement and such Tax Return may be filed as
prepared by Buyer, subject to adjustment or amendment upon resolution.  Each of Buyer and RTEA, respectively, shall
be entitled to reimbursement for the reasonable out-of-pocket costs and expenses
that it incurs in connection with such proceeding (including third-party out of
pocket costs and expenses relating to the engagement of such Expert or amending
any Tax Return) from the other party to the extent that the result reached by
the Expert reflects the position advocated by Buyer or RTEA, respectively.  By way of example, if RTEA asserts that it is
entitled to a Tax Benefit Payment of $200 with respect to a particular Taxable
Year and Buyer asserts that RTEA is entitled to a Tax Benefit Payment of $100
with respect to such Taxable Year, and the Expert concludes that RTEA is
entitled to a Tax Benefit Payment of $180 with respect to such Taxable Year,
RTEA shall be entitled to reimbursement of 80% of the reasonable out-of-pocket
costs and expenses that it incurred in connection with such proceeding and
Buyer shall be entitled to reimbursement of 20% of the reasonable out-of-pocket
costs and expenses that it incurred in connection with such proceeding.  Each party may offset its payment obligations
pursuant to the previous two sentences against the payment that it is entitled
to receive pursuant to the previous two sentences.  Notwithstanding the foregoing, if there is a
dispute under Section 4.02 subject to these Reconciliation Procedures and
the Early Termination Notice and Early Termination Schedule are voided pursuant
to Section 4.03(a), Buyer shall pay all out-of-pocket costs and expenses
incurred by RTEA in engaging the Expert and all other reasonable out-of-pocket
costs and expenses incurred by RTEA in connection with the proceeding
hereunder.  Any dispute as to (i) whether
a dispute is a Reconciliation Dispute within the meaning of this Section 7.09,
(ii) the extent that the result reached by the Expert reflects the
positions advocated by Buyer and RTEA, respectively, or (iii) the amount
of the reasonable costs and expenses incurred in connection with such
proceeding, shall be decided by the Expert. The Expert shall finally determine
any Reconciliation Dispute and the determinations of the Expert pursuant to
this Section 7.09 shall be binding on Buyer and RTEA and may be entered
and enforced in any court having jurisdiction.

 

Section 7.10.        Withholding.  Buyer shall be entitled to deduct and
withhold from any payment payable pursuant to this Agreement such amounts as
Buyer is required to deduct and withhold with respect to the making of such
payment under the Code, or any provision of Tax Law. To the extent that amounts
are so withheld and paid 

 

18

 

over to the
appropriate Taxing Authority by Buyer, such withheld amounts shall be treated
for all purposes of this Agreement as having been paid to RTEA.

 

Section 7.11.        Present
and Future Values.  Present and
future values shall be computed on the basis of annual compounding (with
compounding occurring on the last calendar day of each year).

 

Section 7.12.        Confidentiality.  RTEA agrees to keep information that it
learns about CPE’s business and tax matters by virtue of this Agreement
confidential.  RTEA shall have no
obligation to keep any information confidential to the extent that (i) any
such information is or becomes publicly available (except as a result of an act
of RTEA in violation of this Agreement) or is generally known to the business
community or (ii) RTEA reasonably believes that it is legally compelled to
disclose such information to any tribunal, agency, Governmental Authority, or
self-regulatory organization, including, but not limited to, the New York Stock
Exchange, or else stand liable for contempt or suffer other censure or
financial penalty or is otherwise required by Law to disclose such information.
Notwithstanding anything to the contrary herein, RTEA may disclose to any and
all Persons, without limitation of any kind, the tax treatment and tax
structure of Buyer and its Subsidiaries and any of its transactions, and all
materials of any kind (including opinions or other tax analyses) that are
provided to RTEA relating to such tax treatment and tax structure.

 

Section 7.13.        Non-Effect
of Other Tax Receivable Agreements. 
RTEA and Buyer agree that if Buyer or any of its Subsidiaries enters
into any other agreement that obligates Buyer or any of its Subsidiaries to
make payments to another party in exchange for tax benefits conferred upon Buyer
or any of its Subsidiaries, such tax benefits and such payments shall be
ignored for all purposes of this Agreement, including for purposes of
calculating the Actual Buyer Tax Liability and the Hypothetical Buyer Tax
Liability.
