uniformity of treatment of Participants under the Plan. Awards under the Plan may not be assigned
or alienated.

     (b) The establishment of a Performance Target or the granting of an Award under the Plan shall

shall not lessen or affect Patriot’s right to terminate the employment of such Participant.

     (c) No Participant may be granted cash Awards under the Plan to the extent that the maximum
potential payout to such Participant under the Plan in any calendar year exceeds five million

               (b) Except as provided in Section 4.02, Section 9.01 or as set forth in subsection (c) below,
neither Party nor any member of such Party’s Group shall have any Liability to any other Party or
any member of such other Party’s Group based upon, arising out of or resulting from any agreement,
arrangement, course of dealing or understanding existing on or prior to the Effective Time (other
than this Agreement or any Ancillary Agreement or any agreement entered into in connection
herewith or therewith in order to consummate the transactions contemplated hereby or thereby), and
each Party hereby terminates, and shall cause all members in its Group to terminate, any and all
agreements, arrangements, course of dealings or understandings between it or any members in its
Group and the other Party, or any members of its Group, effective as of the Effective Time (other
than this Agreement or any Ancillary Agreement or any agreement entered into in connection
herewith or in order to consummate the transactions contemplated hereby or thereby), unless such
agreement, arrangement, course of dealing or understanding is set forth in any Ancillary Agreement
or on Schedule 2.06(b), and any such Liability, whether or not in writing, which is not
reflected in any Ancillary Agreement or on such Schedule, is hereby irrevocably cancelled,
released and waived effective as of the Effective Time. No such terminated agreement, arrangement,
course of dealing or understanding (including any provision thereof which purports to survive
termination) shall be of any further force or effect after the Effective Time.

 

17

               (c) The provisions of Section 2.06(b) shall not apply to any of the following agreements,
arrangements, course of dealings or understandings (or to any of the provisions thereof):

          (i) any agreement or arrangement to which any Person other than the Parties and their
respective Affiliates is a Party (it being understood that to the extent that the rights and
obligations of the Parties and the members of their respective Groups under any such
agreements or arrangements constitute PEC Assets or Patriot Assets, PEC Liabilities, or
Patriot Liabilities, such agreements or arrangements shall be assigned or retained pursuant
to this Article II); and

          (ii) any agreements, arrangements, commitments or understandings to which any
non-wholly-owned subsidiary or non-wholly-owned Affiliate of PEC or Patriot is a Party.

          Section 2.07. Novation of Liabilities; Consents.

               (a) Each Party, at the request of the other Party, shall use commercially reasonable efforts
to obtain, or to cause to be obtained, any consent, release, substitution or amendment required to
novate or assign all obligations under agreements, arrangements, licenses and other obligations or
Liabilities for which a member of such Party’s Group and a member of the other Party’s Group are
jointly or severally liable and that do not constitute Liabilities of such other Party as provided
in this Agreement (such other Party, the “Other Party”), or to obtain in writing the unconditional
release of all parties to such arrangements (other than any member of the Group who assumed or
retained such Liability as set forth in this Agreement), so that, in any such case, the members of
the applicable Group will be solely responsible for such Liabilities; provided,
however, that no Party shall be obligated to pay any consideration therefor to any third
party from whom any such consent, substitution or amendment is requested (unless such Party is
fully reimbursed by the requesting Party).

               (b) If the Parties are unable to obtain, or to cause to be obtained, any such required
consent, release, substitution or amendment, the Other Party or a member of such Other Party’s
Group shall continue to be bound by such agreement, arrangement, license or other obligation that
does not constitute a Liability of such Other Party and, unless not permitted by Law or the terms
thereof, as agent or subcontractor for such Party, the Party or member of such Party’s Group who
assumed or retained such Liability as set forth in this Agreement (the “Liable Party”) shall, or
shall cause a member of its Group to, pay, perform and discharge fully all the obligations or
other Liabilities of such Other Party or member of such Other Party’s Group thereunder from and
after the Effective Time; provided, however, that the Other Party shall not be
obligated to extend, renew or otherwise cause such agreement, arrangement, license or other
obligation to remain in effect beyond the term in effect as of the Effective Time. The Liable
Party shall indemnify each Other Party and the members of such Other Party’s Group and hold each
of them harmless against any and all Liabilities arising in connection therewith;
provided, that the Liable Party shall have no obligation to indemnify the Other Party or
any member of such Other Party’s Group with respect to any matter to the extent that such Other
Party has engaged in any knowing violation of Law, fraud or misrepresentation in connection
therewith. The Other Party shall, without further

 

18

consideration, promptly pay and remit, or cause to be promptly paid or remitted, to the
Liable Party or to another member of the Liable Party’s Group, all money, rights and other
consideration received by it or any member of its Group in respect of such performance by the
Liable Party (unless any such consideration is an Asset of such Other Party pursuant to this
Agreement). If and when any such Consent, release, substitution or amendment shall be obtained or
such agreement, lease, license or other rights or obligations shall otherwise become assignable or
able to be novated, the Other Party shall promptly assign, or cause to be assigned, all rights,
obligations and other Liabilities thereunder of any member of such Other Party’s Group to the
Liable Party or to another member of the Liable Party’s Group without payment of any further
consideration and the Liable Party, or another member of such Liable Party’s Group, without the
payment of any further consideration, shall assume such rights and Liabilities.

               (a) On the Distribution Date, PEC will assign to Snowberry Land Company (“Snowberry”), a

to amend all agreements or arrangements governing each bank and brokerage account owned by Patriot
or any other member of the Patriot Group (the “Patriot Accounts”), including all Patriot Accounts
listed or described on Schedule 4.01(a), so that such

 

21

Patriot Accounts, if currently linked (whether by automatic withdrawal, automatic deposit, or
any other authorization to transfer funds from or to, hereinafter “linked”) to any bank or
brokerage account owned by PEC or any other member of the PEC Group (the “PEC Accounts”) are

               (b) The Parties agree to take, or cause the respective members of their respective Groups to
take, at the Effective Time (or such earlier time as the Parties may agree), all actions necessary
to amend all agreements or arrangements governing the PEC Accounts so that such PEC Accounts, if

Effective Time, no current or former employee of any member of the Patriot Group shall have any
authority to access or control any PEC Account.

               (c) With respect to any outstanding checks issued by PEC, Patriot, or any of their respective

other Party the amount of such payment or reimbursement without right of set-off.

          Section 4.02. Guaranteed Patriot and PEC Liabilities.

          (a) (i) Patriot shall use commercially reasonable efforts (excluding payment of money
or incurrence of Liabilities) to obtain as promptly as practicable after the Distribution
Date the release of all members of the PEC Group from any obligations with respect to
Guaranteed Patriot Liabilities, including removing all members of the PEC Group from their
obligations as guarantors with respect to the guarantees listed or described on Schedule
4.02(a). In no event shall any member of the Patriot Group take any action with respect
to any Guaranteed Patriot Liabilities which could be reasonably expected to adversely affect
the PEC Group members in any way, including, without limitation, extending the term of any
Guaranteed Patriot Liabilities or increasing the liability guaranteed thereunder, unless the
guarantee or obligation of all PEC Group members is released as to any extended or modified
liability obligations under such Guaranteed Patriot Liabilities or PEC otherwise consents in
writing.

          (ii) If at any time any member of the PEC Group is required by any governmental agency
to arrange or provide letters of credit, surety bonds or other credit arrangements, in
support of Guaranteed Patriot Liabilities constituting Black Lung

other credit arrangements, at its expense.

          (iii) Until such time as Patriot shall have no amounts recorded in its most recent
audited balance sheet in respect of Black Lung Benefit Liabilities, Patriot shall use best
efforts to maintain sufficient capacity under the Senior Credit Facility to permit it to
obtain (subject to the satisfaction of the conditions precedent contained therein) letters
of credit in an aggregate amount equal to not less than the amount of Black Lung Benefit
Liabilities recorded in its most recent audited balance sheet, less the amount of letters of
credit provided by Patriot to any governmental agency in respect of Guaranteed Patriot
Liabilities constituting Black Lung Benefit Liabilities.

          (iv) If (x) at any time prior to June 30, 2011, any member of the Patriot Group shall
have failed to pay any Black Lung Benefit Liabilities when due and any member of the PEC
Group remains obligated with respect to Guaranteed Patriot Liabilities constituting Black
Lung Benefit Liabilities (such PEC Group obligations, the “Black Lung Benefit Guarantees”)
or (y) on June 30, 2011, any member of the PEC Group remains obligated under any Black Lung
Benefit Guarantees, then commencing on the date of such failure (in the case of clause (x))
or on July 1, 2011 (in the case of clause (y)) and continuing in either case until the date
on which no member of the PEC Group has any obligation under any Black Lung Benefit
Guarantee, upon the written request of PEC, Patriot shall use best efforts to obtain letters

less the amount of letters of credit provided by Patriot to any governmental agency in
respect of Guaranteed Patriot Liabilities constituting Black Lung Benefit Liabilities.

issuer of a letter of credit required pursuant to this Section 4.02(a) notifies Patriot that
it does not intend to renew any letter of credit provided pursuant hereto or (B) Patriot’s
capacity to obtain letters of credit under its Senior Credit Facility or otherwise is not
sufficient, or is not expected to be sufficient, to permit Patriot to meet or to continue to
meet its obligations under this Section 4.02(a).

          (b) PEC shall use commercially reasonable efforts (excluding payment of money or incurrence
of Liabilities) to obtain as promptly as practicable after the Distribution Date the release of
all members of the Patriot Group from any obligations with respect to Guaranteed PEC Liabilities
to which they have not been released as of the Distribution Date, including removing all members
of the Patriot Group from their obligations as guarantors with respect to the guarantees listed or
described on Schedule 4.02(b). In no event shall any member of the PEC Group take any
action with respect to any Guaranteed PEC Liabilities which could be reasonably expected to
adversely affect the Patriot Group members in any way including, without limitation, extending the
term of any Guaranteed PEC Liabilities or increasing the liability guaranteed thereunder, unless
the guarantee or obligation of all Patriot Group members is released as to any extended or
modified liability obligations under such Guaranteed PEC Liabilities or Patriot otherwise consents
in writing.

 

23

               (c) In the event that any PEC Group member is required to pay or otherwise satisfy any
Guaranteed Patriot Liabilities, without limiting any of PEC’s rights and remedies against Patriot
under this Agreement or otherwise, in order to secure Patriot’s indemnity obligations to PEC
hereunder in respect of such Guaranteed Patriot Liabilities, PEC shall be entitled to all the
rights of the payee in any property of any member of the Patriot Group pledged as security for
such Guaranteed Patriot Liabilities.

               (d) In the event that Patriot Group member is required to pay or otherwise satisfy any
Guaranteed PEC Liabilities, without limiting any of Patriot’s rights and remedies against PEC

rights of the payee in any property of any member of the PEC Group pledged as security for such
Guaranteed PEC Liabilities.

          Section 4.03. Insurance.

               (a) Directors and Officers and Fiduciary Liability Policies. Following the Distribution, PEC
will maintain directors’ and officers’ liability and fiduciary liability insurance coverage for a
period of six (6) years from the Distribution Date for the directors and officers of Patriot who
were directors or officers of PEC or members of the PEC Group as of the Distribution Date for acts
as directors and officers of members of the PEC Group during periods prior to the Distribution
Date.

               (b) Third Party Policies.

               (i) With respect to Third Party Policies, if an occurrence for which coverage is
available under such Third Party Policies happens prior to the Effective Time, and a claim
arising therefrom has been or is eventually asserted against Patriot or any other member of
the Patriot Group and such claim is reported by Patriot to the carrier, with a copy to PEC,
in accordance with the reporting provision of the applicable policy, then PEC will, or will
cause the members of the PEC Group that are insured thereunder to, (A) continue to provide
Patriot and any other member of the Patriot Group with access to and coverage under the
applicable Third Party Policies and (B) reasonably cooperate with Patriot and take
commercially reasonable actions as may be necessary or advisable to assist Patriot in
submitting such claims under the applicable Third Party Policies, provided that
Patriot shall be responsible for its portion of any deductibles or self-insured retentions
or co-payments legally due and owing relating to such claims. For the avoidance of doubt, if
an occurrence for which coverage is available under such Third Party Policies happens after
the Effective Time, or a claim arising from an occurrence prior to the Effective Time is not
reported by Patriot to PEC on or before the date when such occurrence must be reported to
the carrier under the applicable Third Party Policy, then no payment for any damages, costs
of defense, or other sums with respect to such claim shall be available to Patriot under
such Third Party Policies.

               (ii) With respect to all Third Party Policies, Patriot agrees and covenants (on behalf
of itself and each other member of the Patriot Group, and each other Affiliate of Patriot)
not to make any claim or assert any rights against PEC and any other

 

24

member of the PEC Group (including the captive insurance companies that are insured
under the Third Party Policies), or the unaffiliated third-party insurers of such Third
Party Policies, except as expressly provided under this Section 4.03(b).

          (c) Administration of Third Party Policies; Other Matters.

          (i) From and after the Effective Time, Patriot or a member of the Patriot Group shall
be responsible for the administration of all Third Party Patriot Policies and Patriot shall
be responsible for any premium adjustments, audits, deductible bills, collateral, Taxes and
claims handling charges or other expenses associated with Third Party Patriot Policies.

          (ii) With respect to all Third Party Policies, from and after the Effective Time, the
agent for the applicable policy shall be responsible for the Insurance Administration and
Claims Administration of such Third Party Policies; provided that the retention of
such administrative responsibilities by an agent of Peabody is in no way intended to limit,
inhibit or preclude any right to insurance coverage for any Insured Claim of a named insured
under such Third Party Policies as contemplated by the terms of this Agreement;
provided, further, that the retention of such administrative
responsibilities by an agent of Peabody shall not relieve the Person submitting any Insured
Claim of the primary responsibility for reporting such Insured Claim accurately, completely
and in a timely manner, or of such Person’s authority to settle any such Insured Claim
within any period permitted or required by the relevant Third Party Policy. PEC or any
member of the PEC Group or any agent of PEC shall not settle any Insured Claim of Patriot or
any member of the Patriot Group under the Third Party Policies without first obtaining the
approval of Patriot or another member of the Patriot Group. Such approval shall not be
unreasonably withheld, delayed or conditioned. Patriot shall have the right to utilize its
broker to advocate for their interest.

          (iii) Where Patriot Liabilities are specifically covered under a Third Party Policy for
periods prior to the Effective Time, or where such Third Party Policy covers claims made
after the Effective Time with respect to an occurrence prior to the Effective Time, then
from and after the Effective Time, Patriot may claim coverage for Insured Claims under such
Third Party Policy as and to the extent that such insurance is available up to the full
extent of the applicable limits of liability of such Third Party Policy (and may receive any
Insurance Proceeds with respect thereto as contemplated by Section 4.03(b) or
Section 4.03(c)(v)), subject to the terms of this Section 4.03(c).

          (iv) Except as set forth in this Section 4.03(c), PEC and Patriot shall not be liable
to one another (or any of the members of their respective Groups) for claims, or portions of
claims, not reimbursed by insurers under any Third Party Policy for any reason not within
the control of PEC or Patriot, including coinsurance provisions, deductibles, quota share
deductibles, self-insured retentions, bankruptcy or insolvency of any insurance carrier(s),
Third Party Policy limitations or restrictions, any coverage disputes, any failure to timely
file a claim by PEC or Patriot (or any of the members of their respective Groups), or any
defect in such claim or its processing. The liability of PEC and Patriot to one another for
such claims is expressly limited to the amount of

 

25

Insurance Proceeds received with respect to such claims and allocated to the respective
Parties in accordance with Section 4.03(c)(v). It is expressly understood that the foregoing
provisions in this Section 4.03(c)(iv) shall not limit any Party’s liability to any other
Party for indemnification pursuant to Article VI.

          (v) Except as otherwise provided in Section 4.03(b), Insurance Proceeds received with
respect to claims, costs and expenses under the Third Party Policies shall be paid, as
appropriate, to PEC with respect to the PEC Liabilities, and Patriot, with respect to
Patriot Liabilities. In the event that the aggregate limits on any Third Party Policies are
exceeded by the aggregate of outstanding Insured Claims by the Parties or members of their
respective Groups, the Parties agree to allocate the Insurance Proceeds received thereunder
based upon their respective percentage of the total of their bona fide claims which were
covered under such Third Party Policy, and any Party who has received Insurance Proceeds in
excess of such Party’s respective percentage of Insurance Proceeds shall pay to the other
Party the appropriate amount so that each Party will have received its respective percentage
of Insurance Proceeds pursuant hereto. Each of the Parties agrees to use commercially
reasonable efforts to maximize available coverage under those Third Party Policies
applicable to it, and to take all commercially reasonable steps to recover from all other
responsible parties in respect of an Insured Claim to the extent coverage limits under a
Third Party Policy have been exceeded or would be exceeded as a result of such Insured
Claim.

          (vi) In the event that the Parties or members of their respective Groups have bona fide
claims under any Third Party Policy arising from the same occurrence and for which a
deductible or self-insured retention is payable, the Parties agree that the aggregate amount
of the deductible or self-insured retention paid shall be borne by the Parties in the same
proportion which the Insurance Proceeds received by each such Party bears to the total
Insurance Proceeds received under the applicable Third Party Policy pursuant to
Section 4.03(c)(v), and any Party who has paid more than such allocable share of the
deductible or self-insured retention shall be entitled to receive from the other Party an
appropriate amount so that each Party has borne its allocable share of the deductible or
self-insured retention pursuant hereto.

          (d) Agreement for Waiver of Conflict and Shared Defense. In the event that Insured Claims of
both Parties exist relating to the same occurrence, the Parties shall jointly defend and waive any
conflict of interest necessary to the conduct of the joint defense. Nothing in this Section 4.03
shall be construed to limit or otherwise alter in any way the obligations of the Parties,
including those created by this Agreement, by operation of Law or otherwise.

          (e) Cooperation. The Parties agree to use (and cause the members in their respective Groups
to use) all commercially reasonable efforts to cooperate with respect to the various insurance
matters contemplated by this Section 4.03.

          (f) Miscellaneous.

          (i) Nothing in this Agreement shall be deemed to restrict Patriot or PEC, or any
members of their respective Groups, from acquiring at its own expense any

 

26

insurance Policy in respect of any Liabilities or covering any period. Except as
otherwise provided in this Agreement, from and after the Effective Time, Patriot and PEC
shall be responsible for obtaining and maintaining their respective insurance programs for
their risk of loss and such insurance arrangements shall be separate programs apart from
each other and each will be responsible for its own deductibles and self-insured retentions
for such insurance programs.

          (ii) Each of the Parties intends by this Agreement that a third-party Person, including
a third-party insurer or reinsurer, or other third-party Person that, in the absence of the
Agreement would otherwise be obligated to pay any claim or satisfy any indemnity or other
obligation, shall not be relieved of the responsibility with respect thereto and shall not
be entitled to a “windfall” (i.e., avoidance of the obligation that such Person would have
in the absence of this Agreement). To the extent that any such Person would receive such a
windfall, the Parties shall negotiate in good faith concerning an amendment of this
Agreement.

          Section 4.04. No Hire; No Solicit. None of PEC or Patriot or any member of their
respective Groups will from the Effective Time through and including the one-year anniversary of
the Effective Time, without the prior written consent of the other Party, either directly or
indirectly, on their own behalf or in the service or on behalf of others, (i) solicit, aid, induce
or encourage any individual who is an employee of a member of the other Party’s Group to leave his
or her employment, or (ii) hire any individual who is an employee of a member of the other Party’s
Group; provided, however, that nothing in this Section 4.04 shall be deemed to
prohibit, any general solicitation for employment through advertisements and search firms not
specifically directed at employees of such other applicable Party; provided
further, that the applicable Party has not encouraged or advised such firm to approach any
such employee.

          Section 4.05. Legal Names and Signage. (a) Except as otherwise specifically provided
in any Ancillary Agreement, each Party shall exercise commercially reasonable efforts to cease (and
cause all of the other members of its Group to cease), as soon as reasonably practicable after the
Distribution Date, but in any event within six (6) months thereafter: (i) making any use of any
names or Trademarks that include (A) any of the Trademarks of the other Party or such other Party’s
subsidiaries or Affiliates (including, in the case of Patriot, “Peabody Energy” or “Peabody Energy
Corporation” or any other name or Trademark containing the word “Peabody”) and (B) any names or
Trademarks related thereto including any names or Trademarks confusingly similar thereto or
dilutive thereof (with respect to each Party, such Trademarks of the other Party or any of such
other Party’s subsidiaries or Affiliates, the “Other Party Marks”), and (ii) holding
themselves out as having any affiliation with the other Party or such other Party’s subsidiaries or
Affiliates; provided, however, that the foregoing shall not prohibit any Party or
any member of a Party’s Group from (1) stating in any advertising or any other communication that
it is formerly a PEC affiliate or (2) making use of any Other Party Mark in a manner that would
constitute “fair use” under applicable Law if any unaffiliated third party made such use or would
otherwise be legally permissible for any unaffiliated third party without the consent of the Party
owning such Other Party Mark. In furtherance of the foregoing, as soon as practicable, but in no
event later than three (3) months following the Effective Time, each Party shall (and cause all of
the other members of its Group to) remove, strike over or otherwise obliterate all Other Party
Marks from all of such Party’s and its subsidiaries’ and

 

27

Affiliates’ assets and other materials, including any vehicles, business cards, schedules,
stationery, packaging materials, displays, signs, promotional materials, manuals, forms, websites,
email, computer software and other materials and systems; provided, however, that
Patriot shall promptly after the Effective Time post a disclaimer on the “www.patriotcoal.com”
website informing its customers that as of the Effective Time and thereafter Patriot, and not PEC,
is responsible for the operation of the Patriot Business, including such website and any applicable
services. Any use by any Party or any of such Party’s Subsidiaries or Affiliates of any of the
Other Party Marks as permitted in this Section 4.05 is subject to their compliance with all quality
control and related requirements and guidelines in effect for the Other Party Marks as of the
Effective Time.

               (b) Notwithstanding the foregoing requirements of Section 4.05(a), if any Party or
any member of such Party’s Group exercised good faith efforts to comply with
Section 4.05(a) but is unable, due to regulatory or other circumstance beyond its control,
to effect a legal name change in compliance with applicable Law such that an Other Party Mark
remains in such Party’s or its Group member’s legal name, then such Party or its relevant Group
member will not be deemed to be in breach hereof as long as it continues to exercise good faith
efforts to effectuate such name change and does effectuate such name change within nine (9) months
after the Effective Time, and, in such circumstances, such Party or Group member may continue to
include in its assets and other materials references to the Other Party Mark that is in such
Party’s or Group member’s legal name which includes references to “Patriot Coal” or “Peabody
Energy” as applicable, but only to the extent necessary to identify such Party or Group member and
only until such Party’s or Group member’s legal name can be changed to remove and eliminate such
references.

               (c) Notwithstanding the foregoing requirements of Section 4.05(a), Patriot shall not be
required to change any name including the word “Peabody” in any third-party contract or license,
or in property records with respect to real or personal property, if an effort to change the name
is commercially unreasonable; provided, however, that (i) Patriot on a prospective
basis from and after the Effective Time shall change the name in any new or amended third-party
contract or license or property record and (ii) Patriot shall not advertise or make public any
continued use of the “Peabody” name permitted by this Section 4.05(c).

          Section 4.06. Auditors and Audits; Annual and Quarterly Financial Statements and
Accounting.

               (a) Each Party agrees that during the period ending one hundred and eighty (180) days
following the Effective Time and in any event solely with respect to the preparation and audit of
each of the Party’s financial statements for any of the years ended December 31, 2007, 2006 and
2005, the printing, filing and public dissemination of such financial statements, the audit of
each Party’s internal control over financial reporting related to such financial statements and
such Party’s management’s assessment thereof, if applicable, and each Party’s management’s
assessment of such Party’s disclosure controls and procedures related to such financial
statements:

               (i) Annual Financial Statements. Each Party shall provide to the other Party on a
timely basis all information reasonably required to meet its schedule for the

 

28

preparation, printing, filing, and public dissemination of its annual financial
statements and, to the extent applicable to such Party, for management’s assessment of the
effectiveness of its disclosure controls and procedures and its internal control over
financial reporting in accordance with all applicable provisions of Regulation S-K,
including, without limitation, Items 307 and 308 of Regulation S-K and, to the extent
applicable to such party, its auditor’s audit of its internal control over financial
reporting and management’s assessment thereof in accordance with Section 404 of the
Sarbanes-Oxley Act of 2002 and the Commission’s and Public Company Accounting Oversight
Board’s rules and auditing standards thereunder (such assessments and audit being referred
to as the “Internal Control Audit and Management Assessments”). Without limiting the
generality of the foregoing, each Party will provide all required financial and other
Information with respect to itself and its Subsidiaries to its auditors in a sufficient and
reasonable time and in sufficient detail to permit its auditors to take all steps and
perform all reviews necessary to provide sufficient assistance to the other Party’s auditors
with respect to information to be included or contained in the other Party’s annual
financial statements and to permit the other Party’s auditors and management to complete the
Internal Control Audit and Management Assessments.

               (ii) Access to Personnel and Records. With respect to the 2007 fiscal year of each of
PEC and Patriot, if PEC and Patriot use a different independent auditor then each audited
Party shall authorize, and use commercially reasonable efforts to cause, its respective
auditors to make available to the other Party’s auditors (the other Party’s auditors,
collectively, the “Other Party’s Auditors”) both the personnel who performed or are
performing the annual audits of such audited party (each such Party with respect to its own
audit, the “Audited Party”) and work papers related to the annual audits of such Audited
Party, in all cases within a reasonable time prior to such Audited Party’s auditors’ opinion
date, so that the Other Party’s Auditors are able to perform the procedures they consider
necessary to take responsibility for the work of the Audited Party’s auditors as it relates
to their auditors’ report on such other Party’s financial statements, all within sufficient
time to enable such other Party to meet its timetable for the printing, filing and public
dissemination of its annual financial statements. In such an event, each Party shall make
available to the Other Party’s Auditors and management its personnel and Records in a
reasonable time prior to the Other Party’s Auditors’ opinion date and the other party’s
management’s assessment date so that the Other Party’s Auditors and the other Party’s
management are able to perform the procedures they consider necessary to conduct the
Internal Control Audit and Management Assessments.

               (b) In the event a Party restates any of its financial statements that includes such Party’s
audited or unaudited financial statements with respect to any balance sheet date or period of
operation between January 1, 2004 and December 31, 2007, such Party will deliver to the other
Party a substantially final draft, as soon as the same is prepared, of any report to be filed by
such first Party with the Commission that includes such restated audited or unaudited financial
statements (the “Amended Financial Report”); provided, however, that such first
Party may continue to revise its Amended Financial Report prior to its filing thereof with the
Commission, which changes will be delivered to the other Party as soon as reasonably practicable;
provided, further, however, that such first Party’s financial personnel
will actively consult with the other Party’s financial personnel regarding any changes which such
first Party

 

29

may consider making to its Amended Financial Report and related disclosures prior to the
anticipated filing of such report with the Commission, with particular focus on any changes which
would have an effect upon the other Party’s financial statements or related disclosures. Each
Party will reasonably cooperate with, and permit and make any necessary employees available to,
the other Party, in connection with the other Party’s preparation of any Amended Financial
Reports.

               (c) If any Party or member of its respective Group is required, pursuant to Rule 3-09 of
Regulation S-X or otherwise, to include in its Exchange Act filings audited financial statements
or other information of the other Party or member of the other Party’s Group, the other Party
shall use commercially reasonable efforts (i) to provide such audited financial statements or
other information, and (ii) to cause its outside auditors to consent to the inclusion of such
audited financial statements or other information in the Party’s Exchange Act filings.

               (d) Nothing in this Section 4.06 shall require any Party to violate any agreement with any
third party regarding the confidentiality of confidential and proprietary information relating to
that third party or its business; provided, however, that in the event that a
Party is required under this Section 4.06 to disclose any such information, such Party shall use
commercially reasonable efforts to seek to obtain such third party’s consent to the disclosure of
such information.

          Section 4.07. No Restrictions on Post-Closing Competitive Activities; Corporate
Opportunities.

               (a) Except as expressly provided herein or in any of the Ancillary Agreements, it is the
explicit intent of each of the Parties that this Agreement shall not include any non-competition
or other similar restrictive arrangements with respect to the range of business activities that
may be conducted by the Parties. Accordingly, each of the Parties acknowledges and agrees that
nothing set forth in this Agreement shall be construed to create any explicit or implied
restriction or other limitation on (i) the ability of the other Party hereto to engage in any
business or other activity that competes with the business of such Party, or (ii) the ability of
the other Party to engage in any specific line of business or engage in any business activity in
any specific geographic area.

               (b) Except as expressly provided herein or in any of the Ancillary Agreements, PEC and the
PEC Group shall have the right to, and shall have no duty not to, (i) engage in the same or
similar business activities or lines of business as Patriot or any other member of the Patriot
Group, (ii) do business with any client or customer of Patriot or any other member of the Patriot
Group, and (iii) employ or otherwise engage any officer or employee of Patriot or any other member
of the Patriot Group, and neither PEC nor the PEC Group nor any officer or director thereof shall
be liable to Patriot or any other member of the Patriot Group or any of Patriot’s stockholders for
breach of any fiduciary duty by reason of any such activities of PEC or any other member of the
PEC Group or of such person’s participation therein.

 

30

               (c) Except as expressly provided in the Ancillary Agreements, Patriot and the Patriot Group
shall have the right to, and shall have no duty not to, (i) engage in the same or similar business
activities or lines of business as PEC or any other member of the PEC Group, (ii) do business with
any client or customer of PEC or any other member of the PEC Group, and (iii) employ or otherwise
engage any officer or employee of PEC or any other member of the PEC Group, and neither Patriot
nor the Patriot Group nor any officer or director thereof shall be liable to PEC or any other
member of the PEC Group or any of PEC’s stockholders for breach of any fiduciary duty by reason of
any such activities of Patriot or the Patriot Group or of such person’s participation therein.

               (d) In the event that PEC or any other member of the PEC Group acquires knowledge of a
potential transaction or matter that may be a corporate opportunity for both PEC or any other
member of the PEC Group and Patriot or any other member of the Patriot Group, neither PEC nor any
other member of the PEC Group nor any agent or advisor thereof shall have any duty to communicate
or present such corporate opportunity to Patriot or any other member of the Patriot Group and
shall not be liable to Patriot or any other member of the Patriot Group or to Patriot’s
stockholders for breach of any fiduciary duty as a stockholder of Patriot by reason of the fact
that PEC or any other member of the PEC Group pursues or acquires such corporate opportunity for
itself, directs such corporate opportunity to another person or entity, or does not present such
corporate opportunity to Patriot or any other member of the Patriot Group.

               (e) In the event that Patriot or any other member of the Patriot Group acquires knowledge of
a potential transaction or matter that may be a corporate opportunity for both PEC or any other
member of the PEC Group and Patriot or any other member of the Patriot Group, neither Patriot nor
any other member of the Patriot Group nor any agent or advisor thereof shall have any duty to
communicate or present such corporate opportunity to PEC or any other member of the PEC Group and
shall not be liable to PEC or any other member of the PEC Group or to PEC’s stockholders for
breach of any fiduciary duty as a stockholder of Patriot by reason of the fact that Patriot or any
other member of the Patriot Group pursues or acquires such corporate opportunity for itself,
directs such corporate opportunity to another person or entity, or does not present such corporate
opportunity to PEC or any other member of the PEC Group.

               (f) For the purposes of this Section 4.07, “corporate opportunities” of Patriot or any other
member of the Patriot Group shall include, but not be limited to, business opportunities (i) that
Patriot or any other member of the Patriot Group is financially able to undertake, (ii) that are,
by their nature, in a line of business of Patriot or any other member of the Patriot Group,
including the Patriot Business, (iii) that are of practical advantage to Patriot or any other
member of the Patriot Group, (iv) in which Patriot or any other member of the Patriot Group has an
interest or a reasonable expectancy, and (v) in which, by embracing the opportunities, Patriot or
any other member of the Patriot Group will cause the self-interest of PEC or any other member of
the PEC Group or any of their officers or directors to be brought into conflict with that of
Patriot or any other member of the Patriot Group, and “corporate opportunities” of PEC or any
other member of the PEC Group shall include, but not be limited to, business opportunities (i)
that PEC or any other member of the PEC Group is financially able to undertake, (ii) that are, by
their nature, in a line of business of PEC or any other

 

31

member of the PEC Group, (iii) that are of practical advantage to PEC or any other member of
the PEC Group, (iv) in which PEC or any other member of the PEC Group have an interest or a
reasonable expectancy, and (v) in which, by embracing the opportunities, PEC or any other member
of the PEC Group will cause the self-interest of Patriot or any other member of the Patriot Group
or any of their officers or directors to be brought into conflict with that of PEC or any other
member of the PEC Group.

          Section 4.08. Right of Offset.

               (a) To the extent PEC or any other member of the PEC Group has the right to receive any
amounts hereunder, including under the provisions of Article VI, or under any Ancillary Agreement
or under any other arrangement between any member of the PEC Group and Patriot or any other member
of the Patriot Group, then PEC may satisfy such amounts out of and shall have a right of off-set
against any amounts then currently due from Patriot or any other member of the Patriot Group to
PEC or any other member of the PEC Group hereunder or thereunder. For the avoidance of doubt, the
parties acknowledge that expenses payable by Patriot pursuant to Section 15.01 of this agreement
may be offset against amounts payable to Patriot pursuant to Section 2.02(f). PEC shall be
entitled to offset from the amount to be contributed by it to Patriot pursuant to Section 2.02(f)
of this Agreement an amount representing PEC’s estimate of expenses to be paid by Patriot pursuant
to Section 15.01 hereof. The parties shall conduct a final accounting for such expenses within 60
days of the Distribution Date and related payments required to be made by either Patriot or PEC to
the extent the expenses determined by such final accounting are higher or lower, respectively,
than PEC’s estimate, shall be made not later than 90 days after the Distribution Date.

               (b) To the extent Patriot or any other member of the Patriot Group has the right to receive
any amounts hereunder, including under the provisions of Article VI, or under any Ancillary
Agreement or under any other arrangement between any member of the Patriot Group and PEC or any
other member of the PEC Group, then Patriot may satisfy such amounts out of and shall have a right
of off-set against any amounts then currently due from PEC or any other member of the PEC Group to
Patriot or any other member of the Patriot Group hereunder or thereunder

          Section 4.09. [Intentionally Omitted].

          Section 4.10. Prairie State Permits.

               (a) After the Distribution Date, PEC shall use its commercially reasonable efforts to cause a
member of the Peabody Group to apply for, and diligently pursue, the transfer of the permits held
by PCC and set forth on Schedule 4.10(b) and to cause in connection with such transfers
the replacement of each surety bond, letter of credit or other similar arrangement (collectively,
“Prairie State Bonds”) with respect to the permits set forth on Schedule 4.10(b)
by posting, or causing another party to post, a new bond in form and substance satisfactory to the
applicable beneficiary of such Prairie State Bond.

               (b) Patriot will use commercially reasonable efforts to (i) execute and deliver such further
instruments and documents and take such other actions as PEC may

 

32

reasonably request in order to effectuate the transfer of the permits identified in
Schedule 4.10(b) and (ii) take, or cause to be taken, all actions, and do, or cause to be
done, all things, reasonably necessary, proper or advisable under applicable laws, regulations and
agreements or otherwise to consummate and make effective such transfers, including, without
limitation, using commercially reasonable efforts to obtain any consents and approvals, make any
filings and applications and remove any liens, claims, equity or other encumbrance on an Asset
necessary or desirable in order to effect such transfers; provided that neither Patriot
nor any of its Affiliates shall be obligated to pay any consideration therefor (except for filing
fees and other similar charges) to any third party from whom such consents, approvals and
amendments are requested or to take any action or omit to take any action if the taking of or the
omission to take such action would be unreasonably burdensome to Patriot or the Patriot Group or
the business thereof. PEC shall (i) use commercially reasonable efforts to cooperate with Patriot
in order to effect the transfer of the permits identified in Schedule 4.10(b) and (ii)
promptly reimburse Patriot or its Affiliate, as the case may be, for any filing fee or other
similar charge paid to a third party from whom such consents, approvals and amendments are
requested.

ARTICLE V

LITIGATION MATTERS

          Section 5.01. Case Allocation.

               (a) As of the Distribution Date, Patriot shall, and, as applicable, shall cause the other
members of the Patriot Group to, (i) diligently conduct, at its sole cost and expense, the defense
of the Patriot Actions, including the Patriot Actions listed on Schedule 5.01(a) and any
applicable future Patriot Actions; (ii) notify PEC of material litigation developments related to
the Patriot Actions; and (iii) agree not to file any cross claim or institute separate legal
proceedings against PEC in relation to the Patriot Actions.

               (b) As of the Distribution Date, PEC shall, and, as applicable, shall cause the other members
of the PEC Group to, (i) diligently conduct, at its sole cost and expense, the defense of the PEC
Actions, including the PEC Actions listed on Schedule 5.01(b) and any applicable future
PEC Actions; (ii) notify Patriot of material litigation developments related to the PEC Actions;
and (iii) agree not to file any cross claim or institute separate legal proceedings against
Patriot in relation to the PEC Actions.

               (c) Notwithstanding anything in this Section 5.01 to the contrary, PEC shall have the right
to participate in the defense of any Patriot Action and to be represented by attorneys of its own
choosing and at its sole cost and expense, and Patriot shall have the right to participate in the
defense of any PEC Action and to be represented by attorneys of its own choosing and at its sole
cost and expense.

               (d) Patriot shall indemnify and hold harmless PEC and other members of the PEC Group against
Liabilities arising in connection with Patriot Actions, and PEC shall indemnify and hold harmless
Patriot and other members of the Patriot Group against Liabilities arising in connection with PEC
Actions, in each case, in accordance with the indemnification provisions of Article VI.

 

33

               (e) As of the Distribution Date, PEC shall, and, as applicable, shall cause the other members
of the PEC Group to, (i) diligently conduct the defense of the Joint Actions; (ii) notify Patriot
of material litigation developments related to the Joint Actions; and (iii) agree not to file any
cross claim or institute separate legal proceedings against Patriot in relation to the Joint
Actions; provided that if it becomes clear that a Joint Action relates primarily to the
Patriot Business then from and after such time such Joint Action shall instead be deemed to be a
Patriot Action subject to clause (a) above; and provided, further, that if it
becomes clear that a Joint Action does not relate primarily to the Patriot Business then from and
after such time such Joint Action shall instead be deemed to be a PEC Action subject to clause (b)
above. PEC and Patriot shall regularly meet to review and discuss the progress of the Joint
Actions and the classification thereof. Any dispute regarding whether an Action remains a Joint
Action shall be settle pursuant to the dispute resolution mechanics of Section 15.15.

               (f) Until such time as the respective Liabilities of the members of the PEC Group and Patriot
Group are determined in connection with any Joint Action, PEC and Patriot shall each pay 50% of
the cost and expenses associated with the defense of such Joint Action. The parties agree that,
to effect the foregoing sharing arrangement, counsel in connection with any Joint Action shall be
instructed to render separate bills to PEC and to Patriot. In the event that PEC pays any costs
or expenses that are the responsibility of Patriot hereunder, Patriot shall promptly reimburse PEC
for such amounts. Patriot shall have the right to employ separate counsel to represent it and
members of the Patriot Group if Patriot shall have reasonably concluded that there may be a legal
defense available to members of the Patriot Group that are different from or in addition to those
available to PEC or representation of both PEC (or any member of the PEC Group) and Patriot (or
any member of the Patriot Group) by the same counsel would be inappropriate due to actual or
potential differing interests between them, in which case fees and expenses of such counsel
incurred by Patriot shall be included in the amounts allocated by the next sentence of this
paragraph (f). Upon the determination of Liability of the members of the PEC Group and Patriot
Group in connection with any Joint Action, Patriot shall indemnify and hold harmless PEC and other
members of the PEC Group against the portion of such Liabilities relating primarily to the Patriot
Business, and PEC shall indemnify and hold harmless Patriot and other members of the Patriot Group
against the portion of such Liabilities relating primarily to the PEC Business, including, in each
case, the costs and expenses associated with the defense of such Joint Action since the beginning
of such Joint Action, which shall be allocated between PEC and Patriot in proportion to the
Liability with respect to such Joint Action of members of the PEC Group, on the one hand, and
members of the Patriot Group, on the other hand. Indemnification pursuant to this Section 5.01(f)
shall be in accordance with the indemnification provisions of Article VI.

               (g) [Intentionally Omitted].

               (h) [Intentionally Omitted].

               (i) As of the Distribution Date, PEC shall assume the responsibility of litigating the case
of Clintwood Elkhorn Mining Co. v. United States, pending before the United States Court of
Appeals for the Federal Circuit (the “Black Lung Case”). PEC shall receive and have the
benefit of all of the proceeds of the Black Lung Case, including interest, and shall be
responsible for the payment of attorneys’ fees and costs.

 

34

               (j) As of the Distribution Date, PEC shall assume the responsibility of litigating
Consolidated Coal Co. v. United States, No. 01-254C, pending in the United States Court of Federal
Claims (the “Federal Reclamation Case”). PEC shall receive and have the benefit of all of
the proceeds of the Federal Reclamation Case, including interest, and shall be responsible for the
payment of attorneys’ fees and costs in connection with the Federal Reclamation Case.

          Section 5.02. Litigation cooperation.

               (a) Each of PEC and Patriot agrees that at all times from and after the Effective Time, if an
Action currently exists or is commenced by a third-party with respect to which a Party (or any
member of such Party’s respective Group) is a named defendant but such Action is otherwise not a
Liability allocated to such named Party under this Agreement or any Ancillary Agreement, then the
other Party shall use commercially reasonable efforts to cause the named but not liable defendant
to be removed from such Action and such defendant shall not be required to make any payments or
contribution in connection therewith.

               (b) If, in the case of any Action involving a matter contemplated by Section 5.01, there is a
conflict of interest between the Parties, or in the event that any Third Party Claim seeks
equitable relief which would restrict or limit the future conduct of the non-responsible Party or
such Party’s business or operations, such Party shall be entitled to retain, at the responsible
Party’s expense, separate counsel as required by the applicable rules of professional conduct
(which counsel shall be reasonably acceptable to the responsible Party) and to participate in (but
not control) the defense, compromise, or settlement of that portion of the Third Party Claim that
seeks equitable relief with respect to the named Party.

               (c) PEC and Patriot shall each use commercially reasonable efforts to make available to the
other, upon written request, its officers, directors, employees and agents, and the officers,
directors, employees and agents of its subsidiaries, as witnesses to the extent that such
individuals may reasonably be required in connection with any legal, administrative or other
proceedings arising out of the business of the other, or of any entity that is part of the other
Party’s Group in which the requesting Party or a member of its Group may be involved. The
requesting Party shall bear all out-of-pocket costs and expenses in connection therewith. On and
after the Effective Time, in connection with any matter contemplated by this Section 5.02(c), the
Parties will maintain any attorney-client privilege or work product immunity of any member of any
Group as required by the Common Interest Agreement.

ARTICLE VI

INDEMNIFICATION

          Section 6.01. Patriot Indemnification of the PEC Group. On and after the Distribution
Date, Patriot shall indemnify, defend and hold harmless each member of the PEC Group, and each of
their respective directors, officers, employees and agents (the “PEC Indemnitees”) from and against
any and all Indemnifiable Losses incurred or suffered by any of the PEC Indemnitees and arising out
of, or due to, (a) the failure of Patriot or any member of the Patriot Group to pay, perform or
otherwise discharge, any of the Patriot Liabilities and (b) any untrue statement or alleged untrue
statement of any material fact contained in the preliminary or

 

35

final Form 10, the preliminary or final Information Statement or any amendment or supplement
thereto or the omission or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading (other than the information
about PEC included in the sections of the Information Statement attached as Exhibit 99.1 to the
Form 10 entitled “Summary — Our Business,” “Summary – Summary of the Spin-Off,” and “The Spin-Off -
Reasons for the Spin-Off,” or any amendment or supplement thereto); provided, that Patriot
shall have no obligation to indemnify PEC or any other member of the PEC Group with respect to any
matter to the extent that such party has engaged in any knowing violation of Law, fraud or
misrepresentation in connection therewith.

          Section 6.02. PEC Indemnification of Patriot Group. On and after the Distribution
Date, PEC shall indemnify, defend and hold harmless each member of the Patriot Group and each of
their respective directors, officers, employees and agents (the “Patriot Indemnitees”) from and
against any and all Indemnifiable Losses incurred or suffered by any of the Patriot Indemnitees and
arising out of, or due to, (a) the failure of PEC or any member of the PEC Group to pay, perform or
otherwise discharge, any of the PEC Liabilities and (b) any untrue statement or alleged untrue
statement of any material fact regarding PEC included in the sections of the Information Statement
attached as Exhibit 99.1 to the Form 10 entitled “Summary – Our Business,” “Summary — The
Spin-Off,” and “The Spin-Off — Reasons for the Spin-Off,” or any amendment or supplement thereto or
the omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; provided, that PEC shall have no
obligation to indemnify Patriot or any other member of the Patriot Group with respect to any matter
to the extent that such party has engaged in any knowing violation of Law, fraud or
misrepresentation in connection therewith.

          Section 6.03. Contribution. In circumstances in which the indemnity agreements
provided for in Sections 6.01(b) and 6.02(b) are unavailable or insufficient, for any reason, to
hold harmless an indemnified party in respect of any Indemnifiable Losses arising thereunder, each
indemnifying party, in order to provide for just and equitable contribution, shall contribute to
the amount paid or payable by such indemnified party as a result of such Indemnifiable Losses, in
such proportion as is appropriate to reflect the relative fault of the indemnifying party or
parties on the one hand and the indemnified party on the other in connection with the statements or
omissions or alleged statements or omissions that resulted in such Indemnifiable Losses, as well as
any other relevant equitable considerations. The relative fault of the parties shall be determined
by reference to, among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to information supplied
by Patriot or PEC, the Parties’ relative intents, knowledge, access to information and opportunity
to correct or prevent such statement or omission, and any other equitable considerations
appropriate in the circumstances.

          Section 6.04. Insurance and Third Party Obligations. No insurer or any other third
party shall be, by virtue of the foregoing indemnification provisions, (a) entitled to a benefit it
would not be entitled to receive in the absence of such provisions, (b) relieved of the
responsibility to pay any claims to which it is obligated, or (c) entitled to any subrogation
rights with respect to any obligation hereunder.

 

36

          Section 6.05. Indemnification Obligations Net of Insurance Proceeds and Other Amounts on a
Net-Tax Basis.

               (a) Any Liability subject to indemnification or contribution pursuant to this Article VI,
will (i) be net of Insurance Proceeds that actually reduce the amount of the Liability, (ii) be
net of any proceeds received by an Indemnified Party from any third party for indemnification for
such Liability that actually reduce the amount of the Liability (“Third Party Proceeds”) and
(iii) will be determined on a Net-Tax Basis. Accordingly, the amount which any Indemnifying Party
is required to pay pursuant to this Article VI to any Indemnified Party will be reduced by any
Insurance Proceeds or Third Party Proceeds theretofore actually recovered by or on behalf of the
Indemnified Party in respect of the related Liability. If an Indemnified Party receives a payment
required by this Agreement from an Indemnifying Party in respect of any Liability (an “Indemnity
Payment”) and subsequently receives Insurance Proceeds or Third Party Proceeds, then the
Indemnified Party will pay to the Indemnifying Party an amount equal to the excess of the
Indemnity Payment received over the amount of the Indemnity Payment that would have been due if
the Insurance Proceeds or Third Party Proceeds had been received, realized or recovered before the
Indemnity Payment was made.

               (b) An insurer who would otherwise be obligated to pay any claim shall not be relieved of the
responsibility with respect thereto or, solely by virtue of the indemnification and contributions
provisions hereof, have any subrogation rights with respect thereto. The Indemnified Party shall
use commercially reasonable efforts to seek to collect or recover any third-party Insurance
Proceeds and any Third Party Proceeds to which the Indemnified Party is entitled in connection
with any Liability for which the Indemnified Party seeks contribution or indemnification pursuant
to this Article VI; provided that the Indemnified Party’s inability to collect or recover
any such Insurance Proceeds or Third Party Proceeds shall not limit the Indemnifying Party’s
obligations hereunder.

               (c) The term “Net-Tax Basis” as used in this Article VI means that, in determining the amount
of the payment necessary to indemnify any party against, or reimburse any party for, Liabilities,
the amount of such Liabilities will be determined net of any theoretical reduction in Tax
realizable (assuming a hypothetical effective tax rate of 40%) by the Indemnified Party as the
result of sustaining or paying such Liabilities after taking into account any Tax incurred on the
receipt of Insurance Proceeds, and the amount of such Indemnity Payment will be increased (i.e.,
“grossed up”) by the amount necessary to satisfy any income or franchise Tax liabilities that will
be incurred by the Indemnified Party as a result of its receipt of, or right to receive, such
Indemnity Payment (as so increased), so that the Indemnified Party is put in the same net
after-Tax economic position as if it had not incurred such Liabilities, in each case without
taking into account any impact on the Tax basis that an Indemnified Party has in its assets.

          Section 6.06. Notice and Payment of Claims. If any PEC or Patriot Indemnitee (the
“Indemnified Party”) determines that it is or may be entitled to indemnification by a Party (the
“Indemnifying Party”) under this Article VI (other than in connection with any Action or claim
subject to Section 6.07), the Indemnified Party shall deliver to the Indemnifying Party a written
notice specifying, to the extent reasonably practicable, the basis for its claim for
indemnification and the amount for which the Indemnified Party reasonably believes it is entitled

 

37

to be indemnified. After the Indemnifying Party shall have been notified of the amount for
which the Indemnified Party seeks indemnification, the Indemnifying Party shall, within 30 days
after receipt of such notice, pay the Indemnified Party such amount in cash or other immediately
available funds (or reach agreement with the Indemnified Party as to a mutually agreeable
alternative payment schedule) unless the Indemnifying Party objects to the claim for
indemnification or the amount thereof. If the Indemnifying Party does not give the Indemnified
Party written notice objecting to such claim and setting forth the grounds therefor within the same
30 day period, the Indemnifying Party shall be deemed to have acknowledged its liability for such
claim and the Indemnified Party may exercise any and all of its rights under applicable law to
collect such amount.

          Section 6.07. Notice and Defense of Third Party Claims. Promptly following the earlier
of (a) receipt of notice of the commencement by a third party of any Action against or otherwise
involving any Indemnified Party or (b) receipt of information from a third party alleging the
existence of a claim against an Indemnified Party, in either case, with respect to which
indemnification may be sought pursuant to this Agreement (a “Third Party Claim”), the Indemnified
Party shall give the Indemnifying Party written notice thereof. The failure of the Indemnified
Party to give notice as provided in this Section 6.07 shall not relieve the Indemnifying Party of
its obligations under this Agreement, except to the extent that the Indemnifying Party is
prejudiced by such failure to give notice. Within 30 days after receipt of such notice, the
Indemnifying Party shall by giving written notice thereof to the Indemnified Party, (a)
acknowledge, as between the parties hereto, liability for, and at its option elect to assume the
defense of such Third Party Claim at its sole cost and expense or (b) object to the claim of
indemnification set forth in the notice delivered by the Indemnified Party pursuant to the first
sentence of this Section 6.07 setting forth the grounds therefor; provided that if the
Indemnifying Party does not within the same 30 day period give the Indemnified Party written notice
acknowledging liability or objecting to such claim and setting forth the grounds therefor, the
Indemnifying Party shall be deemed to have acknowledged, as between the parties hereto, its
liability to the Indemnified Party for such Third Party Claim. Any contest of a Third Party Claim
as to which the Indemnifying Party has elected to assume the defense shall be conducted by
attorneys employed by the Indemnifying Party and reasonably satisfactory to the Indemnified Party;
provided that the Indemnified Party shall have the right to participate in such proceedings
and to be represented by attorneys of its own choosing at the Indemnified Party’s sole cost and
expense. If the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnifying
Party may settle or compromise the claim without the prior written consent of the Indemnified
Party; provided that the Indemnifying Party may not agree to any such settlement pursuant
to which any remedy or relief, other than monetary damages for which the Indemnifying Party shall
be responsible hereunder, shall be applied to or against the Indemnified Party, without the prior
written consent of the Indemnified Party, which consent shall not be unreasonably withheld. If the
Indemnifying Party does not assume the defense of a Third Party Claim for which it has acknowledged
liability for indemnification under Article VI, the Indemnified Party may require the Indemnifying
Party to reimburse it on a current basis for its reasonable expenses of investigation, reasonable
attorney’s fees and reasonable out-of-pocket expenses incurred in defending against such Third
Party Claim, and the Indemnifying Party shall be bound by the result obtained with respect thereto
by the Indemnified Party; provided that the Indemnifying Party shall not be liable for any
settlement effected without its consent, which consent shall not be unreasonably withheld. The
Indemnifying Party shall pay to the Indemnified Party in cash the

 

38

amount for which the Indemnified Party is entitled to be indemnified (if any) within 15 days
after the final resolution of such Third Party Claim (whether by the final nonappealable judgment
of a court of competent jurisdiction or otherwise), or, in the case of any Third Party Claim as to
which the Indemnifying Party has not acknowledged liability, within 15 days after such Indemnifying
Party’s objection has been resolved by settlement, compromise or the final nonappealable judgment
of a court of competent jurisdiction.

other entity that is part of such other’s respective Group or to the business and affairs of such
other entity.

          Section 13.02. Access to Information. From and after the Effective Time, PEC and
Patriot shall each afford the other and its accountants, counsel and other designated
representatives reasonable access (including using commercially reasonable efforts to give

 

40

access to Persons possessing information) and duplicating rights during normal business hours
to all records, books, contracts, instruments, computer data and other data and information in its
possession relating to the business and affairs of the other or a member of its Group (other than
data and information subject to an attorney/client or other privilege), insofar as such access is
reasonably required by the other including, without limitation, for audit, accounting and
litigation purposes.

          Section 13.03. Retention of Records. Except as otherwise required by law or agreed to
in writing, each Party shall, and shall cause the members of its Group to, retain all information
relating to the other’s business in accordance with the past practice of such Party.
Notwithstanding the foregoing, either Party may destroy or otherwise dispose of any information at
any time in accordance with the corporate record retention policy maintained by such Party with
respect to its own records.

          Section 13.04. Confidentiality.

               (a) Notwithstanding any termination of this Agreement, for a period of five (5) years from
the Effective Time the Parties shall hold, and shall cause each of their respective subsidiaries
to hold, and shall each cause their respective officers, employees, agents, consultants and
advisors to hold, in strict confidence, and not to disclose or release or use, for any ongoing or
future commercial purpose, without the prior written consent of the other Party, any and all
Confidential Information concerning any other Party; provided, that the Parties may
disclose, or may permit disclosure of, Confidential Information (i) to their respective auditors,
attorneys, financial advisors, bankers and other appropriate consultants and advisors who have a
need to know such information for our auditing and other non-commercial purposes and are informed
of their obligation to hold such information confidential to the same extent as is applicable to
the Parties and in respect of whose failure to comply with such obligations, the applicable Party
will be responsible, (ii) if the Parties or any of their respective subsidiaries are required or
compelled to disclose any such Confidential Information by judicial or administrative process or
by other requirements of Law or stock exchange rule, (iii) as required in connection with any
legal or other proceeding by one Party against any other Party, or (iv) as necessary in order to
permit a Party to prepare and disclose its financial statements, or other required disclosures;
provided, further, that each Party (and members of its Group as necessary) may
use, or may permit use of, Confidential Information of the other Party in connection with such
first Party performing its obligations, or exercising its rights, under this Agreement or any
Ancillary Agreement. Notwithstanding the foregoing, in the event that any demand or request for
disclosure of Confidential Information is made pursuant to clause (ii) above, each Party, as
applicable, shall promptly notify the other of the existence of such request or demand and shall
provide the other a reasonable opportunity to seek an appropriate protective order or other
remedy, which such Parties will cooperate in obtaining. In the event that such appropriate
protective order or other remedy is not obtained, the Party whose Confidential Information is
required to be disclosed shall or shall cause the other applicable Party or Parties to furnish, or
cause to be furnished, only that portion of the Confidential Information that is legally required
to be disclosed and shall take commercially reasonable steps to ensure that confidential treatment
is accorded such information.

 

41

               (b) Notwithstanding anything to the contrary set forth herein, (i) the Parties shall be
deemed to have satisfied their obligations hereunder with respect to Confidential Information if
they exercise the same degree of care (but no less than a reasonable degree of care) as they take
to preserve confidentiality for their own similar information and (ii) confidentiality obligations
provided for in any agreement between each Party or its Subsidiaries and their respective
employees shall remain in full force and effect. Notwithstanding anything to the contrary set
forth herein, Confidential Information of any Party in the possession of and used by any other
Party as of the Effective Time may continue to be used by such Party in possession of the
Confidential Information in and only in the operation of the PEC Business or the Patriot Business,
as the case may be; provided, such Confidential Information may be used only so long as
the Confidential Information is maintained in confidence and not disclosed in violation of
Section 13.04(a). Such continued right to use may not be transferred (directly or indirectly) to
any third party without the prior written consent of the applicable Party, except pursuant to
Section 15.05(b).

               (c) Each Party acknowledges that it and the other members of its Group may have in their
possession confidential or proprietary information of third parties that was received under
confidentiality or non-disclosure agreements with such third party prior to the Effective Time.
Such Party will hold, and will cause the other members of its Group and their respective
representatives to hold, in strict confidence the confidential and proprietary information of
third parties to which they or any other member of their respective Groups has access, in
accordance with the terms of any agreements entered into prior to the Effective Time between one
or more members of the such Party’s Group (whether acting through, on behalf of, or in connection
with, the separated businesses) and such third parties.

               (d) Upon the written request of a Party, the other Party shall promptly, (i) deliver to such
requesting Party all original Confidential Information (whether written or electronic) concerning
such requesting Party and/or its Subsidiaries, and (ii) if specifically requested by such
requesting Party, destroy any copies of such Confidential Information (including any extracts
there from). Upon the written request of such requesting Party, the other Party shall cause one of
its duly authorized officers to certify in writing to such requesting Party that the requirements
of the preceding sentence have been satisfied in full.

          Section 13.05. Privileged Matters.

               (a) The Parties recognize that legal and other professional services that have been and will
be provided prior to the Effective Time have been and will be rendered for the collective benefit
of each of the members of the PEC Group and the Patriot Group, and that each of the members of the
PEC Group and the Patriot Group should be deemed to be the client with respect to such
pre-separation services for the purposes of asserting all privileges which may be asserted under
applicable Law.

               (b) The Parties recognize that legal and other professional services will be provided
following the Effective Time which will be rendered solely for the benefit of PEC or Patriot, as
the case may be. With respect to such post-separation services, the Parties agrees as follows:

 

42

               (i) PEC shall be entitled, in perpetuity, to control the assertion or waiver of all
privileges in connection with privileged information which relates solely to the PEC
Business, whether or not the privileged information is in the possession of or under the
control of PEC or Patriot. PEC shall also be entitled, in perpetuity, to control the
assertion or waiver of all privileges in connection with privileged information that relates
solely to the subject matter of any claims constituting PEC Liabilities, now pending or
which may be asserted in the future, in any lawsuits or other proceedings initiated against
or by PEC, whether or not the privileged information is in the possession of or under the
control of PEC or Patriot; and

               (ii) Patriot shall be entitled, in perpetuity, to control the assertion or waiver of
all privileges in connection with privileged information which relates solely to the Patriot
Business, whether or not the privileged information is in the possession of or under the
control of PEC or Patriot. Patriot shall also be entitled, in perpetuity, to control the
assertion or waiver of all privileges in connection with privileged information that relates
solely to the subject matter of any claims constituting Patriot Liabilities, now pending or
which may be asserted in the future, in any lawsuits or other proceedings initiated against
or by Patriot, whether or not the privileged information is in the possession of or under
the control of PEC or Patriot.

               (c) The Parties agree that they shall have a shared privilege, with equal right to assert or
waive, subject to the restrictions in this Section 13.05, with respect to all privileges not
allocated pursuant to the terms of Section 13.05(b). All privileges relating to any claims,
proceedings, litigation, disputes, or other matters which involve both PEC and Patriot in respect
of which both Parties retain any responsibility or Liability under this Agreement, shall be
subject to a shared privilege among them.

               (d) No Party may waive any privilege which could be asserted under any applicable Law, and in
which any other Party has a shared privilege, without the consent of the other Party, which shall
not be unreasonably withheld or delayed or as provided in subsections (e) or (f) below. Consent
shall be in writing, or shall be deemed to be granted unless written objection is made within
twenty (20) days after notice upon the other Party requesting such consent. Each Party shall use
its reasonable best efforts to preserve any privilege held by the other party if that privilege is
a shared privilege or has been allocated to the other party pursuant to Section 13.05(b).

               (e) In the event of any litigation or dispute between or among any of the Parties, or any
members of their respective Groups, either such Party may waive a privilege in which the other
Party or member of such Group has a shared privilege, without obtaining the consent of the other
Party; provided, that such waiver of a shared privilege shall be effective only as to the
use of information with respect to the litigation or dispute between the relevant Parties and/or
the applicable members of their respective Group’s, and shall not operate as a waiver of the
shared privilege with respect to third parties.

               (f) If a dispute arises between the Parties or their respective subsidiaries regarding
whether a privilege should be waived to protect or advance the interest of either Party, each
Party agrees that it shall negotiate in good faith, shall endeavor to minimize any

 

43

prejudice to the rights of the other Party, and shall not unreasonably withhold consent to
any request for waiver by the other Party. Each Party specifically agrees that it will not
withhold consent to waiver for any purpose except to protect its own legitimate interests.

               (g) Upon receipt by either Party or by any subsidiary thereof of any subpoena, discovery or
other request which arguably calls for the production or disclosure of information subject to a
shared privilege or as to which the other Party has the sole right hereunder to assert a
privilege, or if either Party obtains knowledge that any of its or any of its Subsidiaries’
current or former directors, officers, agents or employees have received any subpoena, discovery
or other requests which arguably calls for the production or disclosure of such privileged
information, such Party shall promptly notify the other Party of the existence of the request and
shall provide the other Party a reasonable opportunity to review the information and to assert any
rights it or they may have under this Section 13.05 or otherwise to prevent the production or
disclosure of such privileged information.

               (h) The transfer of all Information pursuant to this Agreement is made in reliance on the
agreement of PEC and Patriot as set forth in Section 13.04 and Section 13.05, to maintain the
confidentiality of privileged information and to assert and maintain all applicable privileges.
Nothing provided for herein or in any Ancillary Agreement shall be deemed a waiver of any
privilege that has been or may be asserted under this Agreement or otherwise.

          Section 13.06. Ownership of Information. Any Information owned by one Party or any of
its subsidiaries that is provided to a requesting Party pursuant to Article VI, Article XV, or this
Article XIII shall be deemed to remain the property of the providing party. Unless specifically set
forth herein, nothing contained in this Agreement shall be construed as granting or conferring
rights of license or otherwise in any such information.

          Section 13.07. Separation of Data. Patriot acknowledges and agrees that PEC may, after
the Effective Time, delete or cause to be deleted any Information which does not relate to the
Patriot Business which is contained in, stored in or accessible through any Software provided to
Patriot under the Software License Agreement, the Transition Services Agreement or otherwise. The
foregoing will not be deemed to be a violation of any provision of this Agreement, the Software
License Agreement, or the Transition Services Agreement. The provisions of Section 13.04 apply to
Patriot’s use of any such Information prior to its deletion.

ARTICLE XIV

INTEREST ON PAYMENTS

          Section 14.01. Interest. Except as otherwise expressly provided in this Agreement or
an Ancillary Agreement, all payments by one Party to the other under this Agreement or any
Ancillary Agreement shall be paid by company check or wire transfer of immediately available funds
to an account in the United States designated by the recipient, within thirty (30) days after
receipt of an invoice or other written request for payment setting forth the specific amount due
and a description of the basis therefor in reasonable detail. Any amount remaining unpaid beyond
its due date, including disputed amounts that are ultimately determined to be payable, shall bear
interest at a rate of simple interest per annum equal to the Applicable Rate. Notwithstanding
anything to the contrary contained herein or in any Ancillary Agreement, in no

 

44

event shall the amount or rate of interest due and payable exceed the maximum amount or rate
of interest allowed by applicable law and, in the event any such excess payment is made or
received, such excess sum shall be credited as a payment of principal (or if no principal shall
remain outstanding, shall be refunded).

               (a) Neither Party (referred to in this Section 15.05(a) as a “Transferring Party”) shall
consolidate with or merge into any other entity or convey, transfer or lease all or any
substantial portion of its properties and assets to any entity, unless, in each case, the other
party to such transaction expressly assumes, by a written agreement, executed and delivered to the
other Party hereto, in form reasonably satisfactory to such other Party, all of the Liabilities of
the Transferring Party under this Agreement and the Ancillary Agreements and the due and punctual
performance or observance of every agreement and covenant of this Agreement and Ancillary
Agreements on the part of the Transferring Party to be performed or observed.

               (b) Neither of the Parties hereto may assign its rights or delegate any of its duties under
this Agreement without the prior written consent of each other Party. This Agreement shall be
binding upon, and shall inure to the benefit of, the Parties hereto and their respective
successors and permitted assigns. Nothing contained in this Agreement, express or implied, is
intended to confer any benefits, rights or remedies upon any Person other than members of the PEC
Group and the Patriot Group and the PEC Indemnitees and Patriot Indemnitees under Article VI

Article VI shall not be terminated or amended after the Distribution in respect of any PEC
Indemnitee or Patriot Indemnitee without the consent of such Person.

reasonable efforts to obtain any consents and approvals, make any filings and applications and
remove any liens, claims, equity or other encumbrance on an Asset of the other Party necessary or
desirable in order to consummate the transactions contemplated by this Agreement; provided
that no Party hereto shall be obligated to pay any consideration therefor (except for filing fees
and other similar charges) to any third party from whom such consents, approvals and amendments are
requested or to take any action or omit to take any action if the taking of or the omission to take
such action would be unreasonably burdensome to the Party or its Group or the business thereof.

          Section 15.07. Severability. In the event that any one or more of the provisions
contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained herein shall not in any
way be affected or impaired thereby, and the Parties 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 15.08. Governing Law; Jurisdiction. This Agreement shall be construed in
accordance with, and governed by, the laws of the State of Delaware, without regard to the
conflicts of law rules of such state. Each of the parties hereto (a) consents to submit itself to
the personal jurisdiction of the courts of the State of Missouri or any federal court with subject
matter jurisdiction located in the City of St. Louis (and any appeals court therefrom) in the event
any dispute arises out of this Agreement or any Ancillary Agreement or any transaction contemplated
hereby or thereby, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction
by motion or other request for leave from any such court, and (c) agrees that it will not bring any
action relating to this Agreement or any Ancillary Agreement or any transaction contemplated hereby
or thereby in any court other than such courts.

          Section 15.09. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original instrument, but all of which together shall
constitute but one and the same Agreement.

          Section 15.10. Third Party Beneficiaries. Except as provided in Article VI and except
as specifically provided in any Ancillary Agreement, this Agreement is solely for the benefit of
the Parties and should not be deemed to confer upon third parties any remedy, claim, liability,
reimbursement, cause of action or other right in excess of those existing without reference to this
Agreement.

          Section 15.11. Specific Performance. The Parties agree that irreparable damage would
occur in the event that the provisions of this Agreement were not performed in accordance

 

47

with their specific terms. Accordingly, it is hereby agreed that the Parties shall be entitled
to provisional or temporary injunctive relief in accordance therewith in any court of the United
States, this being in addition to any other remedy or relief to which they may be entitled.

          Section 15.12. Limitations of Liability. Notwithstanding anything in this Agreement to
the contrary, no Indemnifying Party shall be liable to an Indemnified Party for any special,
indirect, incidental, punitive, consequential, exemplary, statutorily-enhanced or similar damages
in excess of compensatory damages (provided that any such liability with respect to a Third Party
Claim shall be considered direct damages) arising in connection with the transactions contemplated
by this Agreement or the Ancillary Agreements.

          Section 15.13. Force Majeure. No Party (or any Person acting on its behalf) shall have
any liability or responsibility for failure to fulfill any obligation (other than a payment
obligation) under this Agreement or, unless otherwise expressly provided therein, any Ancillary
Agreement, so long as and to the extent to which the fulfillment of such obligation is prevented,
frustrated, hindered or delayed as a consequence of circumstances of Force Majeure. A Party
claiming the benefit of this provision shall, as soon as reasonably practicable after the
occurrence of any such event: (a) notify the other Party of the nature and extent of any such Force
Majeure condition, and (b) use due diligence to remove any such causes and resume performance under
this Agreement as soon as reasonably practicable.

          Section 15.14. Construction. The Parties have participated jointly in the negotiation
and drafting of this Agreement. This Agreement shall be construed without regard to any presumption
or rule requiring construction or interpretation against the party drafting or causing any
instrument to be drafted.

          Section 15.15. Disputes.

               (a) Except as otherwise provided in any Ancillary Agreement, all disputes, controversies or
claims between members of the PEC Group and the Patriot Group, which are parties to this Agreement
or any Ancillary Agreement, arising out of or relating to this Agreement or any Ancillary
Agreement or the performance by the parties of its or their terms, whether based on contract,
tort, statute or otherwise, including, but not limited to, disputes in connection with claims by
third parties (collectively, “Disputes”), shall be resolved only in accordance with the provisions
of this Section 15.15; provided, however, that nothing contained herein shall
preclude any party to a Dispute from seeking or obtaining (i) injunctive relief to prevent an
actual or threatened breach of any of the provisions of this Agreement or any Ancillary Agreement,
or (ii) equitable or other judicial relief to enforce the provisions of this Section 15.15 hereof
or to preserve the status quo pending resolution of Disputes hereunder.

               (b) Any party or parties to a Dispute of either Group may give the parties to the Dispute of
the other Group written notice of the Dispute initiating the procedures hereunder. Within ten days
after delivery of the notice of a Dispute, the receiving parties shall submit to the other a
written response. The notice and the response shall include a statement of each party’s respective
position and a summary of arguments supporting that position and the name and title of the
executive who will represent the claimants and of any other individual

 

48

who will accompany such executive in resolving the Dispute. Within twenty (20) days after
delivery of the first notice, the executives of both Groups shall meet at a mutually acceptable
time and place, and thereafter as often as they reasonably deem necessary, and shall negotiate in
good faith to attempt to resolve the Dispute. All reasonable requests for information made by one
party to the another will be honored. If the Dispute has not been resolved by negotiation within
forty (40) days of the notice of the Dispute, the board of directors of PEC and Patriot shall
appoint independent committees that will negotiate in good faith to attempt to resolve the
Dispute.

               (c) If the Dispute has not been resolved by negotiation within sixty (60) days of the notice
of Dispute, the Dispute may, by mutual consent of both Parties, be submitted for resolution by a
panel of three arbitrators conducted in accordance with the CPR Rules for Non-Administered
Arbitration or AAA Rules (the “Rules”), as modified by this Section 15.15. The Claimants acting
jointly, on the one hand, and the Respondents acting jointly, on the other hand, shall each
appoint one arbitrator within fourteen (14) days after the Claimants give an arbitration notice.
The two arbitrators so appointed shall designate the third arbitrator by mutual agreement within
30 days after the arbitration notice is given. If the two arbitrators so appointed fail to
designate the third arbitrator within such period, then any Party may request the International
Institute for Conflict Prevention & Resolution (“CPR”) to appoint the third arbitrator within
fourteen (14) days after such request. The third arbitrator shall be a lawyer licensed to practice
in the State of Missouri who shall not be related to, employed by, affiliated with or have had a
substantial or ongoing business relationship with any member of either Group. Notwithstanding the
foregoing, if the amount in dispute is less than $5,000,000, then the Claimants and Respondents
shall appoint, together, a single arbitrator, reasonably acceptable to them, licensed to practice
in the State of Missouri who shall not be related to, employed by, affiliated with or have had a
substantial or ongoing business relationship with any member of either Group.

               (d) The arbitration shall be conducted in St. Louis, Missouri (or at any other place agreed
upon by the parties and the arbitrators). The parties will facilitate the arbitration by: (i)
making available to one another and to the arbitrators for examination, inspection and extraction
all documents, books, records and personnel under their control if determined by the arbitrators
to be relevant to the dispute; (ii) conducting arbitration hearings to the greatest extent
possible on successive days; and (iii) observing strictly the time periods established by this
Section 15.15, the Rules or by the arbitrators for submission of evidence or briefs. All issues in
connection with the Dispute, including procedural issues, shall be decided by the concurrence of
at least two arbitrators, and all decisions by the arbitrators shall be accompanied by a written
opinion setting forth the findings of fact and conclusions of law relied upon in reaching the
decision. The panel of arbitrators shall decide the issues submitted to it in accordance
with the language and commercial purposes of this Agreement or the relevant Ancillary Agreement
(as applicable); provided that all questions of law shall be governed by the internal laws
of the State of Delaware, without regard to its conflict of laws rules. The arbitrators’ decision
shall be final and binding as to all matters at issue in the Dispute; provided,
however, if necessary such decision may be enforced by either party in any court having
jurisdiction over the parties or the subject matter of the Dispute. Unless the arbitrators shall
assess the costs and expenses of the arbitration proceeding and of the parties differently,

 

49

each party shall pay its costs and expenses incurred in connection with the arbitration
proceeding, and the costs and expenses of the arbitrators shall be shared equally by the parties.
