exercise the right to borrow or withdraw on the policy cash values. Where the Bank and the

right or interest the Bank may have in such proceeds, as provided in this Agreement.

	 	4.	 	PREMIUM PAYMENT METHOD.

Subject to the Bank’s absolute right to surrender or terminate the policy at any time and
for any reason, the Bank shall pay an amount equal to the planned premiums and any other

	 	6.	 	DIVISION OF DEATH PROCEEDS.

Subject to Paragraphs 7 and 9 herein, the division of the death proceeds of the policy is
as follows:

	 	A.	 	Provided that the Insured is either employed by the Bank at the time
of death, or that the Insured is no longer employed by the Bank because he has
elected Early or Normal Retirement from the Bank (as defined in the Insured’s
Individual Participation Agreement in conjunction with the Nevada Security Bank
Executive Supplemental Compensation Plan), then the Insured’s beneficiary(ies)
shall be entitled to the following:

	 	i.	 	If the Insured is Sixty-Nine (69) years old or
younger at the time of death, then the Insured’s beneficiary(ies),
designated in accordance with Paragraph 3, shall be entitled to receive a
total amount equal to the lesser of XXX,XXX. Dollars or one hundred
percent (100%) of the Net-at-Risk portion of the proceeds from the
Policy(ies). For the purposes of this Agreement, the Net-at-Risk insurance
portion is the total proceeds of the Policy less the cash value of the
Policy. The Executive may elect to reduce their death benefit in the
future at any time provided that they have written authorization from
their spouse or primary beneficiary.

	 	ii.	 	If the Insured dies after attaining the age of
Seventy (70), but before attaining the age of Eighty (80) years old, then
the Insured’s beneficiary(ies), designated in accordance with Paragraph 3,
shall be entitled to receive a total amount equal to the lesser of XXX,XXX
Dollars or one hundred percent (100%) of the Net-at-Risk portion of the
proceeds from the Policy(ies).

	 	iii.	 	If the Insured dies after attaining Eighty (80) years
of age, then the Insured’s beneficiaries, designated in accordance with
Paragraph 3, shall be entitled to receive a total amount equal to the
lesser of XXX,XXX Dollars or one hundred percent (100%) of the Net-at-Risk
portion of the proceeds from the Policy(ies).

	 	B.	 	In the event the Insured is forced to terminate his position as a
result of Disability, or, in the event the Insured’s position as an Executive is
terminated as a result of a Change in Control or as an event of Constructive
Termination, then the Insured’s beneficiaries shall be entitled to receive the
same amounts to which they would otherwise be entitled under Paragraph 6A above.

	 	C.	 	Should the Executive be involuntarily terminated (other than as a
result of a Change in Control or as an event of Constructive Termination) before
the Early Retirement Age specified in his Executive Supplemental Compensation
Agreement, then Insured’s beneficiary(ies) will receive Eighty Percent (80%) of
the Net-at-Risk portion of the proceeds under the Policy(ies). For the purposes of
this Agreement, a termination shall be considered involuntary if Insured’s
position as an Executive is terminated by the Bank, and such termination is not
For Cause, not as a Result of a Change in Control, and not as a result of
Disability.

	 	D.	 	Should the Executive be Terminated for Cause or should he Voluntarily
resign his positions as an Executive before the Early Retirement Age specified in
their Executive Supplemental Compensation Agreement, the beneficiary(ies) will
receive a total amount equal to the lesser of Twenty-Five Thousand Dollars
($25,000) in death benefits or One Hundred Percent (100%) of the Net-at-Risk
portion of the proceeds under the Policy(ies).

	 	E.	 	The Bank and the Insured (or assignees) shall share in any interest
due on the death proceeds on a pro rata basis as the proceeds due each
respectively bears to the total proceeds, excluding any such interest.

F. In the event that either the Policy(ies) is terminated or the proceeds of the

Policy(ies) are insufficient to provide the benefit specified herein, other than as
a result of any intentional act of the Insured which results in the termination of
the Policy(ies), then the Bank shall pay to the Insured’s beneficiary(ies) an
amount which, when combined with the proceeds of the Policy(ies) actually received,
will provide a total after tax death benefit equal to the benefit level specified
in Subparagraphs 6 (A), (B), (C) or (D).

	 	7.	 	DIVISION OF THE CASH SURRENDER VALUE OF THE POLICY.

The Bank shall at all times be entitled to an amount equal to the Policy’s cash value, as
that term is defined in the Policy contract, less any Policy loans and unpaid interest or
cash withdrawals previously incurred by the Bank and any applicable surrender charges.
Such cash value shall be determined as of the date of surrender or death as the case may
be.

	 	8.	 	RIGHTS OF PARTIES WHERE POLICY ENDOWMENT OR ANNUITY ELECTION EXISTS.

In the event the Policy involves an endowment or annuity element, the Bank’s right and
interest in any endowment proceeds or annuity benefits, on expiration of the deferment
period, shall be determined under the provisions of this Agreement by regarding such
endowment proceeds or the commuted value of such annuity benefits as the Policy’s cash
value. Such endowment proceeds or annuity benefits shall be considered to be like death
proceeds for the purposes of division under this Agreement.

	 	9.	 	OPTION UPON TERMINATION OF AGREEMENT.

Upon termination of this Agreement by the Bank, but prior to the termination of the
Policy(ies) by the Bank, the Insured (or assignee) shall have a fifteen (15) day option to
receive from the Bank an absolute assignment of the Policy(ies) in consideration of a cash
payment to the Bank, whereupon this Agreement shall terminate. Such cash payment referred
to hereinabove shall be the greater of:

	 	A.	 	The Bank’s share of the cash value of the policy on the date of such
assignment, as defined in this Agreement; or

	 	B.	 	The amount of the premiums that have been paid by the Bank prior to the date
of such assignment.

If, within said fifteen (15) day period, the Insured fails to exercise said option, fails
to procure the entire aforestated cash payment, or dies, then the option shall terminate
and the Insured (or assignee) agrees that all of the Insured’s rights, interest and claims
in the Policy(ies) shall terminate as of the date of the termination of this Agreement.

The Insured expressly agrees that this Agreement shall constitute sufficient written notice
to the Insured of the Insured’s option to receive an absolute assignment of the Policy(ies)
as set forth herein.

Except as provided above, this Agreement shall terminate upon distribution of the death
benefit proceeds in accordance with Paragraph 6 above.

	 	10.	 	INSURED’S OR ASSIGNEE’S ASSIGNMENT RIGHTS.

any breach or default by Seller or the Subsidiary under any such Contract occurring or arising
prior to the Closing Date;

(ii) customer advances, customer deposits and construction advances, unperformed service

(iii) the Assumed Environmental Liabilities;

(iv) Taxes for periods on and after the Closing Date to the extent Buyer is legally obligated
to pay such Taxes in accordance with Article XI; and

(v) Proceedings based on conduct, actions, inaction, facts, circumstances or conditions
arising or occurring on or after the Closing Date, Proceedings described in Schedule 2.2,
Proceedings arising from or related to any other Assumed Liability; and

(c) obligations and liabilities of Buyer and its Affiliates under the Employee Agreement.

The liabilities, responsibilities and obligations to be assumed by Buyer or retained by the
Subsidiary pursuant to this Section 2.2 are hereinafter collectively referred to as the “Assumed
Liabilities.” Subject to the other terms and conditions of this Agreement, Buyer, for itself and
each of its Affiliates (including the Subsidiary upon Closing), hereby irrevocably and
unconditionally waives and releases Seller from all Assumed Liabilities and all liabilities or
obligations relating to the Business or the Assets to the extent arising from events or occurrences
on or after the Closing Date or to the extent otherwise relating to the period after the Closing.
Notwithstanding anything in this Section 2.2 to the contrary, Assumed Liabilities shall not include
any liabilities, responsibilities or obligations expressly stated to be Retained Liabilities
pursuant to Section 2.3.

	 	 	 	Section 2.3. Retained Liabilities.

Buyer shall not assume, and Seller shall retain and pay, perform and discharge when due, all
of the liabilities and obligations, of every kind and nature, relating to or arising from the
following (collectively, the “Retained Liabilities”):

(a) all obligations of Seller or the Subsidiary with respect to any indebtedness for money
borrowed by Seller or the Subsidiary (including items due to Seller’s Affiliates), including,
without limitation, the Retained Indebtedness and payment obligations arising on or after the
Closing Date relating to the Business under any equipment or vehicle lease or under any line
extension Contracts or similar construction arrangements, it being understood and agreed that such
leases, Contracts and similar arrangements do not create indebtedness for money borrowed;

(b) Taxes for periods prior to the Closing Date to the extent Seller or the Subsidiary is

(c) Excluded Assets and all liabilities or obligations of Seller and its Affiliates related to
their businesses other than the Business;

Closing Date, but expressly excluding any such liabilities or obligations for Proceedings relating
to Assumed Liabilities (including Proceedings described in Section 2.2(b)(v)), and all liabilities
or obligations relating to the matter set forth on Schedule 2.3(b); and

(f) obligations and liabilities of Seller and its Affiliates under the Employee Agreement.

Seller, for itself and each of its Affiliates, hereby irrevocably and unconditionally waives and
releases Buyer and each of its Affiliates from all Retained Liabilities.

	 	 	 	Section 2.4. Condition on Assignment or Assumption of Contracts and Rights.

Anything in this Agreement to the contrary notwithstanding, this Agreement shall not
constitute an agreement to assign or assume any Contract or any claim or right or any benefit
arising thereunder or resulting therefrom if an attempted assignment or assumption thereof, without
the Consent of a third party thereto, would constitute a breach thereof. Any transfer or
assignment to Buyer by Seller of any property or property rights or any Contract that requires the
Consent of any third party shall be made subject to such Consent being obtained. If such Consent
is not obtained, or if an attempted assignment thereof would be ineffective or would affect the
rights of Seller thereunder such that Buyer would not in fact receive all such rights, Seller will
cooperate with Buyer in any arrangement, including an operating or other services agreement if
reasonably required by Buyer, reasonably designed to provide for Buyer, at Seller’s cost, the
benefits under any such Contract or rights including, without limitation, enforcement for the
benefit of Buyer of any and all rights of Seller against a third party or Governmental Body thereto
arising out of the breach or cancellation by such third party or Governmental Body or otherwise.
To the extent that Buyer does receive all of the benefits of any such Contract or rights pursuant
to the preceding sentence, such Contract shall be a Contract deemed to have been assigned or
transferred to Buyer pursuant to Section 2.2(b)(i). Notwithstanding the foregoing, Seller shall
not be obligated (although Buyer is permitted at its expense) to provide any arrangement or effect
any assignment pursuant to this Section 2.4 (i) that results in an out-of-pocket cost or
expenditure by Seller, or exposure to or continuation of liability to Seller, resulting from such
arrangements and assignments, that would be reasonably estimated to be in excess of $350,000, in
the aggregate, except as otherwise expressly provided for by this Agreement, or (ii) where Seller
has continuing liability or exposure due to any third party’s failure to release Seller as a result
of such third party’s unwillingness to accept Buyer as assignee; provided, however, that if Buyer,
at Buyer’s option, indemnifies Seller from such continuing liability or exposure on terms and
conditions reasonably satisfactory to Seller, then Seller shall provide an arrangement or
assignment of the Contract to Buyer.

	 	 	 	Section 2.5. Settlement of Intercompany Accounts.

At or prior to the Closing, Seller shall cause all intercompany payables, receivables and
loans between PG Energy and the Subsidiary, on the one hand, and Seller and its Affiliates (other
than PG Energy and the Subsidiary), on the other hand, to be settled or cancelled.

ARTICLE III.

PURCHASE PRICE

Section 3.1. Purchase Price. Subject to the terms and conditions of this Agreement, the
aggregate purchase price (the “Purchase Price”) for the Assets owned directly by Seller and for the
Stock shall be an amount equal to FIVE HUNDRED EIGHTY MILLION DOLLARS ($580,000,000) in cash (the
“Estimated Purchase Price”), as adjusted in accordance with Section 3.2 (as so adjusted, the “Final
Purchase Price”), plus the assumption by Buyer at Closing of the Assumed Liabilities.

	 	 	 	Section 3.2. Adjustment to Estimated Purchase Price.

(a) Within 90 days following the Closing Date, Seller shall prepare and deliver to Buyer a
statement (the “Closing Statement”), utilizing the same accounting methods, policies, practices,
procedures and adjustments as were used in the preparation of the Base Statement (and otherwise in
accordance with GAAP, with such exceptions to GAAP as indicated on Schedule 1.1(a)) and
shall set forth in reasonable detail the amount of Working Capital of the Business as of 12:01 a.m.
on the Closing Date (as well as the adjustments contemplated in Section 6.8), and a calculation of
the adjustment to the Estimated Purchase Price that is payable based upon the difference between
the Working Capital Target and the Working Capital in the Closing Statement. Buyer agrees, at no
cost to Seller, to give Seller and its authorized representatives reasonable access to such
employees, officers and other facilities and such books and records of Buyer and the Subsidiaries
as are reasonably necessary to allow Seller and its authorized representatives to prepare the
Closing Statement. The Closing Statement shall be prepared in accordance with Schedule
1.1(a). The Base Statement was prepared using the same accounting methods, policies,
practices, procedures and adjustments as were used in the preparation of the Financial Statements
and otherwise in accordance with GAAP (and with such exceptions to GAAP as indicated on
Schedule 1.1(a)).

(b) Following its receipt from Seller of the Closing Statement, Buyer shall have 15 Business
Days to review the Closing Statement and to inform Seller in writing of any disagreement (the
“Objection”) that it may have with the Closing Statement, which objection shall specify in
reasonable detail Buyer’s disagreement with the Closing Statement. If Seller does not receive the
Objection within such 15-Business Day period, the amount of Working Capital set forth on the
Closing Statement delivered pursuant to Section 3.2(a) shall be deemed to have been accepted by
Buyer and shall become binding upon Buyer. If Buyer does timely deliver an Objection to Seller,
Seller shall then have 15 Business Days from the date of receipt of such Objection (the “Review
Period”) to review and respond to the Objection. Buyer and Seller shall attempt in good faith to
resolve any disagreements with respect to the determination of the Working Capital of the Business
as of the Closing Date or the amount of the adjustment to the Estimated Purchase Price. If they
are unable to resolve all of their disagreements with respect to the determination of Working
Capital of the Business as of the Closing Date or the amount of the adjustment to the Estimated
Purchase Price within 15 Business Days following the expiration of Seller’s Review Period, they may
refer, at the option of either Buyer or Seller, their differences to Ernst & Young, or if Ernst &
Young declines to accept such engagement, another internationally recognized firm of independent
public accountants selected jointly by Buyer and Seller, which accountants shall determine, only
with respect to the disagreements so submitted, whether and to what extent, if any, the amount of
Working Capital of the Business as of the Closing Date set forth in the Closing Statement requires
adjustment. If Buyer and Seller are unable to so select the independent public accountants within
15 Business Days of Ernst & Young declining to accept such engagement, either Buyer or Seller may
thereafter request that the American Arbitration Association make such selection (as applicable,
Ernst & Young, the firm selected by Buyer and Seller or the firm selected by the American
Arbitration Association is herein referred to as the “CPA Firm”). Buyer and Seller shall direct
the CPA Firm to use its reasonable best efforts to render its determination within 30 days after
the issue is first submitted to the CPA Firm. The CPA Firm’s determination shall be conclusive and
binding upon Buyer and Seller. The fees and disbursements of the CPA Firm shall be shared equally
by Buyer and Seller. Buyer and Seller shall make readily available to the CPA Firm all relevant
books and records relating to the Closing Statement and all other items reasonably requested by the
CPA Firm. The Closing Statement as agreed to by Buyer and Seller or as determined by the CPA Firm
shall be referred to as the “Final Closing Statement.”

(c) In the event of a positive difference between Working Capital on the Final Closing
Statement from the Working Capital Target, Buyer shall pay to Seller in cash the amount of such
difference, plus the Settlement Interest thereon. In the event of a negative difference between
the Working Capital Target from the Working Capital on the Final Closing Statement, Seller shall
pay to Buyer in cash the amount of such difference, plus the Settlement Interest thereon. All
amounts payable under this Section 3.2(c) shall be paid within five Business Days of the
determination of the Final Closing Statement by wire transfer of immediately available funds to a
bank account in the United States of America designated in writing by the recipient not less than
one Business Day before such payment.

conducted, to own or use its portion of the Assets and to perform its obligations under all
Contracts to which it is a party. Seller has full corporate power and authority to execute and
deliver this Agreement and the Related Documents to which Seller is a party. Each of Seller and

	 	 	 	Section 5.2. Authority Relative to this Agreement and Binding Effect.

The execution, delivery and performance of this Agreement and the Related Documents by Seller
have been duly authorized by all requisite corporate action. Except as set forth in Schedule

Seller will not result in (a) any conflict with or breach or violation of or default under the
Organizational Documents of Seller or the Subsidiary, (b) a violation or breach of any term or
provision of, or constitute a default or accelerate the performance required under, any indenture,

notice or the passage of time or both, or (c) a violation of any Order of any Governmental Body,
except for such exceptions to the foregoing clauses (b) and (c) that, individually or in the

binding obligations of Seller, enforceable against Seller in accordance with their respective
terms, except as enforceability may be limited by (i) bankruptcy or similar laws from time to time
in effect affecting the enforcement of creditors’ rights generally or (ii) the availability of
equitable remedies generally.

	 	 	 	Section 5.3. Governmental and Other Required Consents.

party is required to be obtained by Seller or the Subsidiary in connection with the execution and
delivery by Seller of this Agreement or the Related Documents or the consummation of the
transactions contemplated by this Agreement or the Related Documents, other than any Consent the
failure of which to be obtained would not be reasonably likely to have a Material Adverse Effect.
Seller has no knowledge of any facts or circumstances relating to Seller, any Subsidiary or their
Affiliates that reasonably would be likely to preclude or prolong either (i) the receipt of such
required consents or (ii) consummation of the transactions contemplated by this Agreement in

otherwise disposed of in accordance with this Agreement. None of the Assets are subject to any
Encumbrance except (a) Encumbrances described in Schedule 5.5 and (b) Permitted
Encumbrances. Except as set forth in Schedule 5.5, Seller or the Subsidiary owns or
possesses all Easements necessary to conduct the Business as now being conducted without any known
conflict with the rights of others, in each case except to the extent that the failure to own or
possess such Easements would not have a Material Adverse Effect. Except in cases that individually
or in the aggregate are not reasonably likely to result in a Material Adverse Effect, (i) Seller or
the Subsidiary enjoys peaceful and undisturbed possession under all material leases of Real
Property, and (ii) to Seller’s Knowledge, all such leases are valid and subsisting and in full
force and effect.

	 	 	 	Section 5.6. Financial Statements.

(a) Schedule 5.6 sets forth the unaudited combined statement of assets and liabilities
of the Business as of September 30, 2005 (the “Balance Sheet”) and the unaudited combined statement

statements as of, and for its fiscal year ended, December 31, 2004, which Seller financial

in Schedule 5.6, the Balance Sheet presents fairly in all material respects the combined
financial condition of the Business as of its date and the statement of profit included in the
Financial Statements presents fairly in all material respects the combined results of operations of
the Business for the period covered thereby. The books and records of Seller and the Subsidiary

respects at the time of such preparation.

(b) Seller and the Subsidiary maintain a system of internal accounting controls with respect
to the Business sufficient to provide reasonable assurance that (i) transactions are executed in
accordance with management’s general or specific authorization; (ii) transactions are recorded as
necessary to permit preparation of financial statements in conformity with GAAP and to maintain
accountability for assets; (iii) access to assets is permitted only in accordance with management’s
general or specific authorization; and (iv) the recorded accountability for assets is compared with

the Business that are designed to ensure that material information relating to the Business is made
known to Seller’s Chief Executive Officer and its Chief Financial Officer by others in the

were established.

	 	 	 	Section 5.7. Compliance with Legal Requirements; Governmental Permits.

Except as relates to tax matters (which are provided for in Section 5.9), employee benefit

pending or Threatened Proceeding (a) that has been commenced against Seller or the Subsidiary that

(b) that challenges, or that may have the effect of preventing, delaying, making illegal or
otherwise interfering with, the transactions contemplated hereby. Except as disclosed in
Schedule 5.8, as of the date of this Agreement, there are no outstanding Orders against
Seller or the Subsidiary that relate to or arise out of the conduct of the Business or the
ownership, condition or operation of the Business or the Assets (other than any Order relating to
rates, tariffs and similar matters arising in the ordinary course of business) which individually
or in the aggregate would have an adverse financial effect on the Business of more than $400,000.

	 	 	 	Section 5.9. Taxes.

Seller or the Subsidiary has filed all United States federal, state and local income Tax
Returns required to be filed by Seller or the Subsidiary or requests for extensions to file such
Tax Returns have been timely filed, and Seller or the Subsidiary has paid and discharged or made
adequate provision for all Taxes (other than Retained Liabilities) except where failure to so file,
pay, discharge or make adequate provision for are not, individually or in the aggregate, reasonably

or the Assets) will be a party to, be bound by or have any obligation under any Tax sharing
agreement or similar agreement or arrangement pursuant to which the Subsidiary or Seller has
assumed an obligation to satisfy any Tax obligations of another person or entity. Up to and
including the Closing Date, Subsidiary has not carried on its business and other activities in such
a way that would result in the recognition by Subsidiary of liabilities for Taxes after the Closing
Date as result of such activities (for example, Subsidiary has not engaged in a Code Section 355
transaction and has not engaged in any activity or accounting practice that is a “reportable
transaction” as defined in Treas. Reg. Section 1.6011-4). The only representations and warranties
given in respect of tax matters are those contained in Section 5.9 and none of the other
representations and warranties shall be deemed to constitute, directly or indirectly, a
representation or warranty in respect of tax matters.

	 	 	 	Section 5.10. Intellectual Property.

names, computer programs, databases, industrial designs and copyrights necessary for the operation
of the Business in the manner in which it is currently being conducted by Seller or the Subsidiary,
except for the failure to possess or have adequate rights to use such properties that would not
have a Material Adverse Effect. Except as set forth on Schedule 5.10, Seller has no
Knowledge of (a) any infringement or claimed infringement by Seller or the Subsidiary of any
patent, trademark, service mark or copyright of others or (b) any infringement of any patent,
trademark, service mark or copyright owned by or under license to Seller or the Subsidiary except
for any such infringements of the type described in clause (a) or (b) that are not, individually or
in the aggregate, reasonably likely to have a Material Adverse Effect.

	 	 	 	Section 5.11. Personal Property.

Except for such exceptions as are not, individually or in the aggregate, reasonably likely to
have a Material Adverse Effect, the machinery and equipment included among the Assets are in normal
operating condition and in a state of reasonable maintenance and repair and are suitable in all
material respects for the purposes for which they are now being used in the conduct of the
Business.

	 	 	 	Section 5.12. Material Contracts.

Schedule 5.12 contains a complete list of all Material Contracts. Except as described
in Schedule 5.12, all of the Material Contracts are in full force and effect as of the date
hereof and, to Seller’s Knowledge, there are no defaults under any such Contracts except for any
failure to be in full force and effect and for any default that, individually or in the aggregate,
will not have a Material Adverse Effect.

	 	 	 	Section 5.13. Employee Benefit Matters.

(a) Schedule 5.13 lists (i) each “Employee Benefit Plan,” as such term is defined in
Section 3(3) of ERISA, that is covered by any provision of ERISA and that is maintained by Seller

to form the basis of any Environmental Claim or Environmental Liability related to the Assets, that
would reasonably be expected to have a Material Adverse Effect.

(vi) Disclosure. Seller has no Knowledge of any material facts related to the Assets
that Seller reasonably believes would form the basis of an Environmental Claim or Environmental
Liability (i) arising from the failure to have the necessary pollution control equipment currently
required or known to be required in the future by applicable Environmental Laws or (ii) relating to
current remediation activities or remediation activities known to be required in the future, in
either case that would reasonably be expected to have a Material Adverse Effect.

	 	 	 	Section 6.2. Covenants of Buyer.

Buyer agrees to observe and perform the following covenants and agreements:

(a) Consents. Buyer will use its commercially reasonable efforts and act diligently
to assist Seller in obtaining all necessary Consents required to consummate the transactions

relating to or involving Seller, the Subsidiary or the Business for which Seller may be
responsible, to discharge its obligations under this Agreement and the other Related Documents to
which it is a party and for other reasonable purposes and will afford Seller reasonable assistance
in connection therewith. Buyer will cause such records to be maintained for not less than seven
years from the Closing Date and will not dispose of such records without first offering in writing
to deliver them to Seller; provided, however, that in the event that Buyer transfers all or a
portion of the Business to any third party during such period, Buyer may transfer to such third
party all or a portion of the books, records, files and documents related thereof, provided such
third party transferee expressly assumes in writing the obligations of Buyer under this Section

available to Seller and its Affiliates, employees, representatives and agents, those employees of
Buyer requested by Seller in connection with any Proceeding, including to provide testimony, to be
deposed, to act as witnesses and to assist counsel; provided, however, that (i) such access to such
employees shall not unreasonably interfere with the normal conduct of the operations of Buyer and
(ii) Seller shall reimburse Buyer for the out-of-pocket costs reasonably incurred by Buyer in
making such employees available to Seller.

any and all Losses (in each case without deduction or set off) incurred on account of Seller’s
guarantees, letters of credit, bonds and other surety instruments on or after the Closing Date
insofar as such Losses relate to events occurring on or after Closing.

	 	 	 	Section 6.3. Governmental Filings.

(a) HSR Act Filing. Buyer and Seller shall make an appropriate filing of a

interviews or depositions, made by the Antitrust Division of the United States Department of
Justice, the United States Federal Trade Commission or the antitrust or competition law authorities
of any other jurisdiction (the “Antitrust Authorities”) and take all other reasonable actions to

an agreement, settlement, consent providing for divestiture, a “hold separate” agreement,
contractual undertakings with third parties or any other relief with the concerned Antitrust
Authority in order to permit the consummation of the transactions contemplated by this Agreement.
Buyer shall exercise its commercially reasonable efforts, and Seller shall cooperate fully with
Buyer, to prevent the entry in any Proceeding brought by an Antitrust Authority or any Governmental
Body of an Order that would prohibit, make unlawful or delay the consummation of the transactions
contemplated by this Agreement. Seller shall not oppose any efforts of Buyer, including Buyer’s
proffer of consent to any Order, to complete lawfully the transactions contemplated by this
Agreement, and shall cooperate in good faith with Buyer and the Antitrust Authorities to the same
effect. Notwithstanding the foregoing, neither party shall be required to agree to any divestiture

prepare and file with each Governmental Body requests for such Consents as may be necessary for the
consummation of the transactions contemplated hereby in accordance with the terms of this
Agreement. Buyer and Seller will diligently pursue such Consents and will cooperate with each
other in seeking such Consents. To such end, the parties agree to make available the personnel and
other resources of their respective organizations in order to obtain all such Consents. Each party
will promptly inform the other party of any communication received by such party from, or given by
such party to, any Governmental Body from which any such Consent is required and of any material
communication received or given in connection with any Proceeding by a private party, in each case
regarding any of the transactions contemplated hereby, and will permit the other party to review
any communication given by it to, and consult with each other in advance of any meeting or
conference with, any such Governmental Body or, in connection with any Proceeding by a private
party, with such other Person, and to the extent permitted by such Governmental Body or other
Person, give the other party the opportunity to attend and to participate in such meetings and
conferences. Neither party shall take any action in connection with obtaining any Consent from any
Governmental Body that is intended to create, allocate, or shift to the other party any liability
arising from the obtaining of such Consent. Notwithstanding the foregoing, neither party shall be
required to agree to any divestiture of or material restriction on, a material business, a material
asset or a material group of related assets that, in any such case, is owned or operated by it or
any of its Affiliates.

corporate symbols and logos owned by Seller or any of its Affiliates other than the PG Marks, the
“Seller Marks”). shall use commercially reasonable efforts to remove from the Assets any and all
Seller Marks and shall amend the relevant Organizational Documents of the Subsidiary to change the
name of the Subsidiary to a name that does not include any Seller Mark or any name or term
confusingly similar to any Seller Mark. Thereafter, Buyer shall not use any Seller Mark or any
name or term confusingly similar to any Seller Mark in connection with the sale of any products or
services, in the corporate or doing business name of any of its Affiliates or otherwise in the
conduct of its or any of its Affiliates’ businesses or operations. In the event that Buyer
breaches this Section 6.4, Seller shall be entitled to specific performance of this Section 6.4 and
to injunctive relief against further violations, as well as any other remedies at law or in equity
available to Seller.

	 	 	 	Section 6.5. Acknowledgment by Buyer.

In order to induce Seller to enter into and perform this Agreement and the Related Documents,
Buyer acknowledges and agrees with Seller as follows:

THE REPRESENTATIONS AND WARRANTIES SET FORTH IN ARTICLE V OF THIS AGREEMENT
CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF SELLER TO
BUYER IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY AND BY THE
RELATED DOCUMENTS, AND THERE ARE NO REPRESENTATIONS, WARRANTIES, COVENANTS,
UNDERSTANDINGS OR AGREEMENTS, ORAL OR WRITTEN, IN RELATION THERETO BETWEEN THE
PARTIES OTHER THAN THOSE INCORPORATED HEREIN AND THEREIN. EXCEPT FOR THE
REPRESENTATIONS AND WARRANTIES EXPRESSLY SET FORTH IN ARTICLE V OF THIS
AGREEMENT, BUYER DISCLAIMS RELIANCE ON ANY REPRESENTATIONS OR WARRANTIES,
EITHER EXPRESS OR IMPLIED, BY OR ON BEHALF OF SELLER OR ITS AFFILIATES OR
REPRESENTATIVES. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, BUYER
ACKNOWLEDGES AND AGREES THAT, EXCEPT AS PROVIDED IN SECTIONS 5.7, 5.11, 5.14
AND 5.21, THERE ARE NO REPRESENTATIONS OR WARRANTIES OF SELLER WITH RESPECT TO
THE CONDITION OF THE ASSETS, COMPLIANCE WITH ENVIRONMENTAL LAWS AND
ENVIRONMENTAL PERMITS OR THE PRESENCE OR RELEASES OF HAZARDOUS MATERIAL IN THE
FIXTURES, SOILS, GROUNDWATER, SURFACE WATER OR AIR ON, UNDER OR ABOUT OR
EMANATING FROM ANY OF THE PROPERTIES OR ASSETS OF SELLER OR THE SUBSIDIARY.

	 	 	 	Section 6.6. Transition Plan.

Within 15 days after the execution date of this Agreement, Buyer shall deliver to Seller a
list of its proposed representatives to a joint transition team, which shall include individuals
with expertise from various functional specialties associated or involved in providing billing,
payroll and other support services provided to the Business by any automated or manual process
using facilities or employees that are not included among the Assets or Transferred Employees.
Seller will add its representatives to such team within 15 days after receipt of Buyer’s list.
Such team will be responsible for preparing as soon as reasonably practicable after the execution
date of this Agreement, and timely implementing, a transition plan that will identify and describe
substantially all of the various transition activities that the parties will cause to occur before
and after the Closing and any other transfer of control matters that any party reasonably believes
should be addressed in such transition plan, including the matters set forth on Exhibit
6.6. Buyer and Seller shall use their commercially reasonable efforts to cause their
Representatives on such transition team to cooperate in good faith and take all reasonable steps
necessary to develop a mutually acceptable transition plan by no later than 60 days after the date
of this Agreement. The terms and conditions governing such transition activities will be more
fully set forth in a transition agreement reasonably satisfactory to the parties, including the
matters set forth on Exhibit 6.6, to be executed and delivered by Buyer and Seller at the
Closing.

	 	 	 	Section 6.7. Purchase of Leased Assets.

Buyer and Seller shall use commercially reasonable efforts to arrange for Buyer, on the
Closing Date, to enter into new lease agreements covering the equipment listed on Schedule
6.7 and leased by the lessors to Seller and/or the Subsidiary as identified on Schedule
6.7 (the “Leased Assets”), or if unable to do so, then for Buyer to purchase any Leased Assets
directly from any such lessor on, or promptly after, the Closing Date upon Buyer’s payment directly
to any lessor of the purchase price for any of the Leased Assets under the applicable lease. In
either case, Buyer shall be responsible for, and shall pay any related transfer, registration,
sales tax and similar fees, including expenses of counsel, if any, associated with any such lease
arrangement or any transfer arising therefrom.

	 	 	 	Section 6.8. Meter Reading.

On and prior to the Closing Date, Seller shall read the customer meters in their normal cycle
and in due course render the related bills to its customers served by the Business. Seller shall
also read each transportation customer meter (collectively, “Large Volume Meters”) on the day
immediately preceding the Closing Date. Seller shall provide Buyer with the last meter reading
from each of the Large Volume Meters made on the day immediately preceding the Closing Date as soon
as practicable after the Closing Date. After the Closing Date, Buyer shall read the customer
meters for their first time, in the normal cycle, and in due course render bills for service during
the period between Seller’s last reading in the normal cycle and Buyer’s first reading in the
normal cycle to the customers. Buyer shall determine the volume of gas sold by Seller prior to the
Closing Date through Large Volume Meters by Seller’s meter readings on the day immediately
preceding Closing Date. Buyer shall determine by allocation the volumes of gas sold by Seller
through all meters other than Large Volume Meters, prior to the Closing Date, and the gas sold by
Seller, on and after the Closing Date and prior to its first meter reading through meters without
charts. Such allocation shall be consistent with Seller’s past practices for unbilled revenues.
Once such determinations have been made by Buyer, the estimated amounts of accounts receivable and
earned but unbilled revenue and any other related payables or liabilities shall be adjusted based
upon such determinations for purposes of the Working Capital adjustment.

	 	 	 	Section 6.9. Insurance.

(a) At Buyer’s request, Seller agrees to use commercially reasonable efforts to assert and
diligently pursue all rights to insurance coverage under the Policies (other than with respect to
Workman’s Compensation and punitive damage policies) and any other past insurance policies of
Seller relating to the Business or the Assets (such insurance policies shall collectively be
referred to herein as the “Insurance Policies”) with respect to insured claims asserted prior to
the Closing for matters included in the Assumed Liabilities pursuant to Section 2.2(b)(v). Seller
shall remit to Buyer all insurance proceeds obtained after Closing with respect to such insured
claims. Furthermore, Seller agrees to use commercially reasonable efforts to negotiate with each
of its insurance companies in order to provide Buyer the benefit of the coverage under the policies
for all claims asserted on or after the Closing Date and to cooperate with Buyer with any efforts
to obtain “tail” coverage, at Buyer’s sole cost, with respect to any “claims made policies.”
Notwithstanding anything herein to the contrary, any recovery of insurance proceeds by Buyer shall
be net of all Seller’s cost and expenses. Seller shall give access to Buyer to all of the
non-privileged information relating to these matters and shall consult with Buyer on the progress
thereof from time to time.

(b) After the Closing, Buyers shall be responsible for, and neither Seller nor any of its
Affiliates shall have any responsibility for, the payment of any deductible amounts or underlying
limits attributable to the Insurance Policies. Buyer acknowledges that certain of the Insurance
Policies may require Seller or any of its Affiliates to provide an indemnity to the insurance
carrier for deductible amounts and to provide collateral to secure such indemnity obligations.
Buyer shall enter into an indemnification agreement in form mutually acceptable to Buyer and Seller
wherein Buyer agrees to indemnify and hold harmless Seller or any of its Affiliates (as applicable)
for any and all of the costs of maintaining such collateral and for any charges made against such
collateral or indemnification payments in connection with claims arising or alleged to arise from
the operations of the Business required to be paid by Seller of any of its Affiliates (as
applicable) under or with respect to such Insurance Policies from and after the Closing Date.

(c) Seller makes no representation or warranty with respect to the applicability, validity or
adequacy of any Insurance Policies, and Seller shall not be responsible to Buyer or any of its
Affiliates for the failure of any insurer to pay under such Insurance Policy.

(d) Nothing in this Agreement is intended to provide or shall be construed as providing a
benefit or release to any insurer or claims service organization of any obligation under any
Insurance Policy. Nothing herein shall be construed as creating or permitting any insurer or
claims service organization the right of subrogation against Seller or Buyer or any of their
Affiliates in respect of payments made by one to the other under any Insurance Policy.

	 	 	 	Section 6.10. Risk of Loss.

The risk of any loss, damage, impairment, confiscation or condemnation of any of the Assets
from any cause whatsoever shall be borne by Seller at all times prior to the Closing, and by Buyer
at all times thereafter. If any such loss, damage, impairment, confiscation or condemnation
occurs, Seller shall apply the proceeds of any insurance policy, judgment or award with respect
thereto to impair, replace or restore the Assets as soon as possible to their prior condition;
provided, however, anything contained in this Agreement to the contrary notwithstanding, Seller
shall not be obligated to expend sums in excess of the proceeds of any insurance policy, judgment
or award with respect to any loss, damage, impairment, confiscation or condemnation of any of the
Assets in order to repair, replace or restore such Assets to their prior condition. The provisions
of this Section 6.10 shall apply in the event (“Casualty Event”) of any damage or destruction to
the Assets which would result in the nonoccurrence of a condition precedent to Buyer’s obligation
to consummate this Agreement. If a Casualty Event shall occur, Buyer at its option, may proceed to
close this Agreement on the Closing Date, in which event Seller shall pay or assign to Buyer the
proceeds from any insurance policies covering Assets subject to the Casualty Event to the extent
such proceeds are received by or payable to Seller and have not been used in or committed to the
restoration or replacement of Assets subject to the Casualty Event as of the Closing Date.

	 	 	 	Section 6.11. Rate Matters.

Seller has advised Buyer that Seller intends, except to the extent otherwise mutually agreed
to by Seller and Buyer, to file a rate case with the PA PUC on or about March 15, 2006. Seller
agrees to prosecute diligently such rate case without regard to the pendency of this transaction to
pursue the full amount to which Seller shall be lawfully entitled. Without limiting the provisions
of Section 6.1(b), Seller shall give Buyer access to all information relating to the rate case and
shall permit Buyer to consult with Seller and its counsel on the progress thereof from time to
time. Notwithstanding the foregoing, Seller shall have discretion to conduct such proceeding in
the manner consistent with the foregoing standards, but Seller shall not settle or compromise such
proceeding without the prior written consent of Buyer, such consent not to be unreasonably
withheld.

	 	 	 	Section 6.12. Outstanding Payments and Bank Accounts.

(a) Notwithstanding anything contained herein to the contrary, (a) all of the bank accounts
and lock boxes of Seller used in or in connection with the Business shall be considered “Assets”
for the purposes of this Agreement and shall be transferred to Buyer at the Closing, (b) any checks
that are in the possession of Seller at the Closing that relate to accounts receivable (or any
other asset) included in the Assets shall be transferred to Buyer at the Closing and (c) any checks
that are in the possession of Seller at the Closing that relate to accounts receivable (or any
other asset) not included in the Assets shall be retained by Seller.

(b) From and after the Closing, (a) if Seller or any of its Affiliates receives or collects
any funds relating to any accounts receivable (or any other asset) included in the Assets, Seller
or its Affiliates shall remit any such amounts to Buyer as promptly as practicable but no later
than ten (10) days after Seller or any of its Affiliates receives such sum, and (b) Seller and its
Affiliates shall promptly forward all mail, remittance, receipts or other mailings received by any
of them relating to the Business to Buyer.

	 	 	 	Section 6.13. Preparation of Audited Financial Statements of the Business.

If requested by Buyer, Seller shall prepare and deliver to Buyer audited consolidated balance
sheets of the Business as of December 31, 2004 and 2005 and audited consolidated statements of
income and cash flows of the Business for the 12-month period ended June 30, 2004, the 6-month
period ended December 31, 2004 and the 12-month period ended December 31, 2005 (such audited
balance sheets and statements of income and cash flows, the “Audited Financials”). If so
requested, Seller shall use commercially reasonable efforts to deliver the Audited Financials to
Buyer by the later of (i) the Closing Date or (ii) September 30, 2006. The Audited Financials
shall be prepared in accordance with GAAP, and shall be accompanied by the unqualified opinion of
the auditors of the Business. Seller shall consult with Buyer on a regular basis regarding the
preparation of the Audited Financials, and Buyer shall reimburse Seller for the auditing fees and
expenses of Seller’s external auditor relating to the preparation of the Audited Financials.
Notwithstanding the foregoing, (i) Buyer shall use commercially reasonable efforts to seek a waiver
from the SEC to minimize or reduce, to the extent practicable, its obligation to provide such
Audited Financials in connection with its public filings or offerings and (ii) Seller’s requirement
to deliver such Audited Financial Statements shall not be a condition to Closing.

	 	 	 	Section 6.14. Collective Bargaining Agreement.

Seller has advised Buyer that Seller intends to negotiate a renewal or extension of the
Collective Bargaining Agreement between PG Energy and International Brotherhood of Electrical
Workers, AFL-CIO, Scranton and Carbondale Operating Areas, including Mid Valley Local Union #2244
(the “CBA”). Seller agrees to negotiate such renewal or extension diligently to achieve
commercially reasonable terms and conditions consistent with past practice. Seller shall give
Buyer access to all information relating to the CBA renewal or extension and shall permit Buyer to
consult with Seller and its counsel on the progress thereof from time to time. Notwithstanding the
foregoing, Seller shall have discretion to conduct such negotiations in the manner consistent with
the foregoing standards, but Seller shall not enter into such renewal or extension without the
prior written consent of Buyer, such consent not to be unreasonably withheld.

ARTICLE IX.

TERMINATION

	 	 	 	Section 9.1. Termination Rights.

This Agreement may be terminated in its entirety at any time prior to the Closing:

(a) By the mutual written agreement of Seller and Buyer;

(b) By Buyer, on the one hand, or Seller, on the other hand, in writing if there shall be in
effect a nonappealable Order prohibiting, enjoining or restricting the transactions contemplated by
this Agreement;

(c) By Buyer, upon the breach in any material respect of any of the representations and
warranties of Seller contained herein or the failure by Seller to perform and comply in any
material respect with any of the agreements and obligations required by this Agreement to be
performed or complied with by Seller, provided that all such breaches or failures are reasonably
likely to result in a Material Adverse Effect and are not cured or otherwise addressed by Seller in
a manner reasonably acceptable to Buyer within 30 days of Seller’s receipt of a written notice from
Buyer that such breaches or failures have occurred (or significant efforts have not been commenced
to cure such misrepresentations or breaches if they are susceptible to cure but not capable of
being cured within such 30 days);

(d) By Seller, upon the breach in any material respect of any of the representations and
warranties of Buyer contained herein or the failure by Buyer to perform and comply in any material
respect with any of the agreements and obligations required by this Agreement to be performed or
complied with by Buyer, provided that such breach or failure is not cured or otherwise addressed by
Buyer in a manner reasonably acceptable to Seller within 30 days of Buyer’s receipt of a written
notice from Seller that such a breach or failure has occurred (or significant efforts have not been
commenced to cure such misrepresentation or breach if it is susceptible to cure but not capable of
being cured within such 30 days);

(e) By either party in writing if the Closing has not occurred by August 25, 2006 (the “Upset
Date”); provided, however, that the right to terminate this Agreement under this Section 9.1(e)
will not be available to any party that is in material breach of its representations, warranties,
covenants or agreements contained herein; and provided further that in the event either party’s
conditions precedent to Closing set forth in Sections 7.1(d) or 7.1(e) or Sections 7.2(d) or 7.2(e)
have not been satisfied prior to the Upset Date but are reasonably capable of being satisfied
thereafter, then either party may request from the other up to four extensions of thirty days each
following written notice to the other; or

(f) By Seller, if at Closing Buyer fails to make the payments required to be made by Buyer at
Closing.

	 	 	 	Section 9.2. Limitation on Right to Terminate; Effect of Termination.

(a) A party shall not be allowed to exercise any right of termination pursuant to Section 9.1
if the event giving rise to the termination right shall be due to the willful failure of such party
seeking to terminate this Agreement to perform or observe in any material respect any of the
covenants or agreements hereunder to be performed or observed by such party.

(b) If this Agreement is terminated as permitted under Section 9.1, such termination shall be
without liability of or to any party to this Agreement, or any shareholder or Representative of
such party; provided, however, that if such termination shall result from the willful failure of
any party to fulfill a condition to the performance of any other party or to perform a covenant of
this Agreement or from a material and willful breach by any party to this Agreement (it being
understood that the failure to cure a breach shall not, by itself, be a willful breach of this
Agreement), then such party shall (subject to the last sentence of this Section 9.2(b)) be fully
liable for any and all damages sustained or incurred by the other party. If prior to Closing
either party to this Agreement resorts to legal proceedings to enforce this Agreement, the
prevailing party in such proceedings shall be entitled to recover all costs incurred by such party
including reasonable attorney’s fees, in addition to any other relief to which such party may be
entitled; provided, however, and notwithstanding anything to the contrary in this Agreement, in no
event shall either party be entitled to receive any punitive, exemplary, special, remote,
speculative, indirect or consequential damages (including any damages on account of lost profits or
opportunities).

ARTICLE X.

EMPLOYEE MATTERS

	 	 	 	Section 10.1. Employee Agreement.

The parties have addressed the transfer of employees and employee benefit matters in a
separate agreement, entitled Employee Agreement, executed and delivered of even date herewith, the
terms and provisions of which agreement are incorporated into this Agreement as if fully set forth
herein and a copy of which is attached hereto as Exhibit 10.1 (the “Employee Agreement”).

ARTICLE XI.

TAX MATTERS

	 	 	 	Section 11.1. Purchase Price Allocation.

Within 180 days after the Closing Date, Buyer and Seller shall use their good faith efforts to
agree upon the allocation (the “Allocation”) of the Purchase Price to the individual assets or
classes of assets within the meaning of Section 1060 of the IRC. If Buyer and Seller agree to such
Allocation, Buyer and Seller covenant and agree that (a) the values assigned to the assets by the
parties’ mutual agreement shall be conclusive and final for all purposes, and (b) neither Buyer nor
Seller will take any position before any Governmental Body or in any Proceeding that is in any way
inconsistent with such Allocation. Notwithstanding the foregoing, if Buyer and Seller cannot agree
to an Allocation, Buyer and Seller covenant and agree to file, and to cause their respective
Affiliates to file, all Tax Returns and schedules thereto (including, for example, amended returns,
claims for refund, and those returns and forms required under Section 1060 of the IRC and any
Treasury regulations promulgated thereunder) consistent with each of such party’s good faith
Allocations, unless otherwise required because of a change in any Legal Requirement.

	 	 	 	Section 11.2. Cooperation with Respect to Like-Kind Exchange.

Buyer agrees that Seller may, at Seller’s election prior to the Closing Date, direct that all
or a portion of the Purchase Price be delivered to a “qualified intermediary” (as defined in
Treasury Regulation Section 1.1031(k) — (g)(4)) in order to enable Seller’s relinquishment of the
Assets to qualify as part of a like-kind exchange of property covered by Section 1031 of the IRC.
If Seller so elects, Buyer shall cooperate with Seller (but without being required to incur any
out-of-pocket costs in the course thereof) in connection with Seller’s efforts to effect such
like-kind exchange, which cooperation shall include, without limitation, taking such actions as
Seller requests in order to enable Seller to qualify such transfer as part of a like-kind exchange
of property covered by Section 1031 of the IRC (including any actions required to facilitate the
use of a “qualified intermediary”), and Buyer agrees that Seller may assign all or part of its
rights and delegate all or part of its obligations under this Agreement to a person or entity
acting as a qualified intermediary to qualify the transfer of the Assets as part of a like-kind
exchange of property covered by Section 1031 of the IRC. Buyer and Seller agree in good faith to
use reasonable efforts to coordinate the transactions contemplated by this Agreement with any other
transactions engaged in by either Buyer or Seller; provided that such efforts are not required to
include an unreasonable delay in the consummation of the transactions contemplated by this
Agreement.

	 	 	 	Section 11.3. Transaction Taxes.

All transfer, documentary, recording, notarial, sales, use, registration, stamp and other
similar taxes, fees and expenses (including, but not limited to, all applicable stock transfer,
real estate transfer or gains Taxes and including any penalties, interest and additions to such
tax) (“Transaction Taxes”) incurred in connection with this Agreement and the transactions
contemplated hereby shall be borne by Buyer, to the extent that Buyer is legally obligated to pay
such Transaction Taxes, and shall be borne by Seller, to the extent Seller is legally obligated to
pay such Transaction Taxes, regardless of whether the tax authority seeks to collect such Taxes
from Seller or Buyer. Buyer and Seller shall cooperate in timely making and filing all Tax Returns
as may be required to comply with the provisions of laws relating to such Transaction Taxes.
Seller shall prepare all tax filings related to any Transaction Taxes. Fifteen days prior to
making such filings, Seller shall provide to Buyer Seller’s work papers for Buyer’s review and
approval. Ten days prior to the filing date, Buyer shall provide to Seller approval of such work
papers. Buyer shall also be responsible for (a) administering the payment of such Transaction
Taxes, (b) defending or pursuing any proceedings related thereto and (c) paying any expenses
related thereto. Seller shall give prompt written notice to Buyer of any proposed adjustment or
assessment of any Transaction Taxes with respect to the transaction, or of any examination of said
transaction in a sales, use, transfer or similar tax audit. In any proceedings, whether formal or
informal, Seller shall permit Buyer to participate and control the defense of such proceeding and
shall take all actions and execute all documents required to allow such participation. Seller
shall not negotiate a settlement or compromise of any Transaction Taxes without the prior written
consent of Buyer, which consent shall not be unreasonably withheld or delayed.

	 	 	 	Section 11.4. Real and Personal Property Taxes.

All real (including public utility realty tax) and personal property Taxes and assessments
arising with respect to the Assets and the assets of Subsidiary, and including for this purpose the
Pennsylvania Utility Real Property Tax (“PURTA”) and any similar utility Taxes of any other
jurisdiction shall be prorated between Buyer and Seller based on the relative periods of time the
Assets were owned by each respective party or their respective Affiliates during the fiscal period
for which such Taxes are imposed by the applicable taxing jurisdiction (as such fiscal period is or
may be reflected on the bill rendered by such taxing jurisdiction, but in the case of Taxes imposed
based on the specific day of ownership of assets, a fiscal period shall be deemed to be the 365 day
period ending with such date). Upon receipt by Buyer of the tax bill, invoice or other statement
regarding such real and personal property Taxes, Buyer shall calculate the pro rata share of such
tax bill, invoice or other statement attributable to Buyer and Seller. Buyer then shall forward,
as soon as practicable, to Seller a copy of such tax bill, invoice or statement along with the
supporting documentation relating to the calculation of the pro rata share to Seller. Seller then
shall forward to Buyer payment in immediately available funds of its pro rata share of such Taxes
as soon as practicable in advance of the due date of the tax bill, invoice or statement and in time
to avoid the incurrence of penalties or interest. Upon its receipt of such payment, Buyer will pay
the full amount of the tax bill, invoice or statement to the applicable taxing authority. In the
event Seller first receives a tax bill, invoice or statement relating to the Assets from a taxing
authority, Seller shall immediately forward such tax bill, invoice or statement to Buyer.

	 	 	 	Section 11.5. Other Taxes.

Except as otherwise provided in Sections 11.3 and 11.4, Seller shall be responsible for (i)
all Taxes (or the non-payment thereof) of Seller and its Subsidiary for all taxable periods ending
on or before the Closing Date and the portion through the end of the Closing Date for any taxable
period that includes (but does not end on) the Closing Date (“Pre-Closing Tax Period”), (ii) all
Taxes of any member of an affiliated, consolidated, combined or unitary group of which Seller or
any its Subsidiary (or any predecessor of any of the foregoing) is or was a member on or prior to
the Closing Date, including pursuant to Treasury Regulation §1.1502-6 or any analogous or similar
state, local, or foreign law or regulation, (iii) any and all Taxes of any Person (other than
Seller and its Subsidiary) imposed on Seller or its Subsidiary as a transferee or successor, by
contract or pursuant to any law, rule, or regulation, which Taxes relate to an event or transaction
occurring on or before the Closing, and (iv) any Taxes of Seller that do not relate to the Business
or the Assets purchased pursuant to this Agreement.

	 	 	 	Section 11.6. Straddle Period.

In the case of any taxable period that includes (but does not end on) the Closing Date (a
“Straddle Period”), the amount of any Taxes based on or measured by income or receipts of Seller
and its Subsidiary for the Pre-Closing Tax Period shall be determined based on an interim closing
of the books as of the close of business on the Closing Date (and for such purpose, the taxable
period of any partnership or other pass-through entity in which Seller or its Subsidiary holds a
beneficial interest shall be deemed to terminate at such time) and the amount of other Taxes of
Seller and its Subsidiary for a Straddle Period that relates to the Pre-Closing Tax Period shall be
deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction the
numerator of which is the number of days in the taxable period ending on the Closing Date and the
denominator of which is the number of days in such Straddle Period.

	 	 	 	Section 11.7. Cooperation on Tax Matters.

Buyer, the Seller and its Subsidiary shall cooperate fully, as and to the extent reasonably
requested by the other Party, in connection with the filing of Tax Returns pursuant to this Article
XI and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall
include the retention and (upon the other Party’s request) the provision of records and information
that are reasonably relevant to any such audit, litigation or other proceeding and making employees
available on a mutually convenient basis to provide additional information and explanation of any
material provided hereunder.

ARTICLE XII.

INDEMNIFICATION

	 	 	 	Section 12.1. Indemnification by Seller.

From and after Closing and subject to the other provisions of this Article XII, Seller shall
indemnify and hold harmless Buyer, its Representatives, Affiliates, successors and permitted
assigns (collectively, the “Buyer Indemnitees”) from and against any and all Losses actually
incurred by a Buyer Indemnitee, and directly resulting from:

(a) any representations and warranties made by Seller in this Agreement not being true and
correct when made or when required by this Agreement to be true and correct, or any breach or
default by Seller in the performance of its covenants, agreements, or obligations under this
Agreement or the Employee Agreement required to be performed prior to Closing;

(b) any breach or default by Seller in the performance of its covenants, agreements, or
obligations under this Agreement or the Employee Agreement required to be performed after Closing;

(c) Seller’s failure to perform or satisfy any of the Retained Liabilities and all liabilities
associated with the Excluded Assets; and

(d) any amount required to be reimbursed by the Business to Chambers Development Company, Inc.
(“Chambers”) pursuant to the third paragraph in Section 4.1 of the Gas Main Extension Deposit
Agreement, dated November 22, 2005, between Chambers and the Business (the “Main Extension
Agreement”) (and any similar successor provision thereto). Notwithstanding the foregoing, Seller
shall not be liable to the Business for any liabilities or losses under this Section 12.1(d) for
any reimbursements of Project Costs pursuant to the third paragraph in Section 4.1 of the Main
Extension Agreement caused by the action or inaction or the Business’s or Business’ failure to
deliver landfill gas in breach of the Firm Transportation Agreement (the “Transportation
Agreement”) between the Business and PEI Power Corporation.

	 	 	 	Section 12.2. Indemnification by Buyer.

From and after Closing and subject to the other provisions of this Article XII, Buyer shall
indemnify and hold harmless Seller, its Representatives, Affiliates, successors and permitted
assigns (collectively, the “Seller Indemnitees”) from and against any and all Losses actually
incurred by a Seller Indemnitee, and directly resulting from:

(a) any representations and warranties made by Buyer in this Agreement not being true and
correct when made or when required by this Agreement to be true and correct, or any breach or
default by Buyer in the performance of its covenants, agreements, or obligations under this
Agreement or the Employee Agreement required to be performed prior to Closing;

(b) any breach or default by Buyer in the performance of its covenants, agreements, or
obligations under this Agreement or the Employee Agreement required to be performed after Closing;
and

(c) the Assumed Liabilities.

	 	 	 	Section 12.3. Limitations on Seller’s Liability.

Notwithstanding anything to the contrary in this Agreement, the liability of Seller under this
Agreement and any documents delivered in connection herewith or contemplated hereby shall be
limited as follows:

(a) IN NO EVENT SHALL SELLER BE LIABLE TO THE BUYER INDEMNITEES FOR ANY EXEMPLARY, PUNITIVE,
SPECIAL, INDIRECT, CONSEQUENTIAL, REMOTE OR SPECULATIVE DAMAGES; provided, however, that if Buyer
is held liable to a third party for any of such damages and Seller is obligated to indemnify Buyer
for the matter that gave rise to such damages, then Seller shall be liable for, and obligated to
reimburse Buyer for, such damages.

(b) Except as provided below, the representations and warranties of Seller set forth in this
Agreement shall survive the Closing until the first anniversary of the Closing Date; provided
however, that (i) the representations and warranties set forth in Section 5.2 (Authority Relative
to this Agreement and Binding Effect), Section 5.5 (Title to Assets; Encumbrances), and Section
5.17 (Brokers) shall survive indefinitely, and (ii) representations and warranties set forth in
Section 5.9 (Taxes) shall survive for a period equal to the applicable statute of limitations for
the taxable year for each Tax. The other terms of this Agreement and the agreements delivered in
connection herewith shall survive the Closing. All representations and warranties, covenants and
agreements of Seller under this Agreement and the indemnities granted by Seller in Section 12.1
shall terminate at 5:00 p.m., East Coast time, on the applicable survival termination date set
forth above; provided, however, that such indemnities shall survive with respect only to any
specific matter that is the subject of a proper Claim Notice delivered in good faith in compliance
with the requirements of this Section 12.3 until the earlier to occur of (i) the date on which a
final nonappealable resolution of the matter described in such Claim Notice has been reached,
including the determination of all related Losses, if any, regardless of when such Losses are
finally determined or (ii) the date on which the matter described in such Claim Notice has
otherwise reached final resolution, including the determination of all related Losses, if any,
regardless of when such Losses are finally determined. In no event shall any amounts be recovered
from Seller under Section 12.1 or otherwise for any matter for which a Claim Notice is not
delivered to Seller prior to the close of business on the applicable expiration date set forth
above.

(c) Notwithstanding anything to the contrary in this Agreement, in no event shall Seller
indemnify the Buyer Indemnitees, or be otherwise liable in any way whatsoever to the Buyer
Indemnitees, for any Losses otherwise subject to indemnification by Seller pursuant to Section
12.1(a) (determined after giving effect to the other provisions of this Section 12.3) until the
Buyer Indemnitees have incurred Losses otherwise indemnifiable pursuant to Section 12.1(a) that in
the aggregate exceed Eight Million Five Hundred Thousand Dollars ($8,500,000) (the “Deductible”),
after which Seller shall then be liable for all Losses incurred by the Buyer Indemnitees that are
indemnifiable pursuant to Section 12.1(a) in excess of such amount up to the maximum amount set
forth in Section 12.3(d). Losses subject to indemnification by Seller pursuant to Section 12.1(a)
relating to any single breach or series of related breaches by Seller shall not constitute Losses,
and therefore shall not be applied toward the Deductible or be indemnifiable hereunder, unless such
Losses relating to any single breach or series of related breaches exceed $50,000. For the
purposes of calculating the Deductible, none of the dollar limitations or Material Adverse Effect
qualifiers contained in the representations and warranties of Article V shall be included in
calculating Losses that comprise the Deductible.

(d) Notwithstanding anything to the contrary in this Agreement, in no event shall Seller
indemnify the Buyer Indemnitees, or be otherwise liable in any way whatsoever to the Buyer
Indemnitees, for any Losses otherwise subject to indemnification by Seller (determined after giving
effect to the other provisions of this Section 12.3) that in the aggregate exceed Fifty Million
Dollars ($50,000,000).

(e) Seller shall have no liability for any claim or Loss (i) that would be covered by
insurance maintained by or for the benefit of Buyer or any Affiliate of Buyer (including any such
insurance coverage applicable to the Business the benefit of which Buyer would realize if Buyer
were to maintain insurance coverage as is customary for the industry in which the Business is
conducted consistent with the coverage described in Schedule 5.19) or for which Buyer
otherwise recovers payments in respect of such Loss from any other source(s) (whether in a lump sum
or stream of payments) or (ii) that is the type normally recoverable by the Business through rates
and is in fact substantially recovered by Buyer through rates, provided that Buyer shall have made
a good faith effort to recover any such claim or loss through rates and that such recovery is not
indeterminable due to the terms of any rate settlement agreed to by Buyer, or is otherwise
recovered by Buyer through rates. No cost or expense relating to any such claim or Loss that is
actually recovered on the basis of the foregoing shall be included in determining the extent of
Losses suffered by the Buyer Indemnitees for purposes of Section 12.3(c) or Section 12.3(d). Buyer
agrees to use its commercially reasonable efforts to give timely and effective written notice to
the appropriate insurance carrier(s) of any occurrence or circumstances that, in the judgment of
Buyer consistent with its customary risk management practices, appear likely to give rise to a
claim against Buyer that is likely to involve one or more insurance policies of Buyer. Any such
notice shall be given in good faith by Buyer without regard to the possibility of indemnification
payments by Seller under Section 12.1, and shall be processed by Buyer in good faith and in a
manner consistent with its risk management practices involving claims for which no third party
contractual indemnification is available. Buyer agrees that (x) if it is entitled to receive
payment from Seller for a Loss, and (y) if Buyer has obtained insurance that may cover the claim or
matter giving rise to such Loss, then (z) such insurance shall be primary coverage and Buyer will
make a claim under such insurance (if such claim can be made in good faith) before enforcing its
right to receive payment from Seller. If at any time subsequent to the receipt by a Buyer
Indemnitee of an indemnity payment from Seller hereunder, such Buyer Indemnitee (or any Affiliate
thereof) receives any recovery, settlement or other similar payment with respect to the Loss for
which it receives such indemnity payment, such Buyer Indemnitee shall promptly pay to Seller an
amount equal to the amount of such recovery, less any expense incurred by such Buyer Indemnitee (or
its Affiliates) in connection with such recovery, but in no event shall any such payment exceed the
amount of such indemnity payment.

(f) Notwithstanding any language contained in any Related Document (including deeds and other
conveyance documents relating to the Real Property), the representations and warranties of Seller
set forth in this Agreement will not be merged into any such Related Document and the
indemnification obligations of Seller, and the limitations on such obligations, set forth in this
Agreement shall control. No provision set forth in any such Related Document shall be deemed to
enlarge, alter or amend the terms or provisions of this Agreement.

	 	 	 	Section 12.4. Limitation on Buyer’s Liability.

IN NO EVENT SHALL BUYER BE LIABLE TO THE SELLER INDEMNITEES FOR ANY EXEMPLARY, PUNITIVE,
SPECIAL, INDIRECT, CONSEQUENTIAL, REMOTE OR SPECULATIVE DAMAGES; provided, however, that if Seller
is held liable to a third party for any of such damages and Buyer is obligated to indemnify Seller
for the matter that gave rise to such damages, then Buyer shall be liable for, and obligated to
reimburse Seller for, such damages.

	 	 	 	Section 12.5. Claims Procedure.

(a) All claims for indemnification under Section 12.1 or 12.2, or any other provision of this
Agreement except as otherwise expressly provided in this Agreement, shall be asserted and resolved
pursuant to this Article XII. Any Person claiming indemnification hereunder is referred to as the
“Indemnified Party” and any Person against whom such claims are asserted hereunder is hereinafter
referred to as the “Indemnifying Party.” In the event that any Losses are asserted against or
sought to be collected from or threatened to be sought from an Indemnified Party by a third party,
including a Governmental Body, said Indemnified Party shall with reasonable promptness provide to
the Indemnifying Party a Claim Notice. The Indemnifying Party shall not be obligated to indemnify
the Indemnified Party with respect to any such Losses if the Indemnified Party fails to notify the
Indemnifying Party thereof in accordance with the provisions of this Agreement in reasonably
sufficient time so that the Indemnifying Party’s ability to defend against the Losses is not
prejudiced. The Indemnifying Party shall have 30 days from the personal delivery or receipt of the
Claim Notice (the “Notice Period”) to notify the Indemnified Party (i) whether or not it disputes
the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to such
Losses and/or (ii) whether or not it desires, at the sole cost and expense of the Indemnifying
Party, to defend the Indemnified Party against such Losses; provided, however, that any Indemnified
Party is hereby authorized prior to and during the Notice Period to file any motion, answer or
other pleading that it shall deem necessary or appropriate to protect its interests or those of the
Indemnifying Party (and of which it shall have given notice and opportunity to comment to the
Indemnifying Party) and not prejudicial to the Indemnifying Party. In the event that the
Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to
defend the Indemnified Party against such Losses, the Indemnifying Party shall have the right to
defend all appropriate proceedings, and with counsel of its own choosing, which proceedings shall
be promptly settled or prosecuted by them to a final conclusion. If the Indemnified Party desires
to participate in, but not control, any such defense or settlement it may do so at its sole cost
and expense. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate
with the Indemnifying Party and its counsel in contesting any Losses that the Indemnifying Party
elects to contest or, if appropriate and related to the claim in question, in making any
counterclaim against the Person asserting the third party Losses, or any cross-complaint against
any Person. No claim may be settled or otherwise compromised without the prior written consent of
the Indemnifying Party.

(b) The Indemnified Party shall provide reasonable assistance to the Indemnifying Party and
provide access to its books, records and personnel as the Indemnifying Party reasonably requests in
connection with the investigation or defense of the Losses. The Indemnifying Party shall promptly
upon receipt of reasonable supporting documentation reimburse the Indemnified Party for
out-of-pocket costs and expenses incurred by the latter in providing the requested assistance.

(c) With regard to third party claims for which Buyer or Seller is entitled to indemnification
under Section 12.1 or 12.2, such indemnification shall be paid by the Indemnifying Party upon (i)
the entry of an Order against the Indemnified Party and the expiration of any applicable appeal
period or (ii) a settlement with the consent of the Indemnifying Party, provided that no such
consent need be obtained if the Indemnifying Party fails to respond to the Claim Notice as provided
in Section 12.5(a). Notwithstanding the foregoing but subject to Section 12.5(a), and provided
that there is no dispute as to the applicability of indemnification, expenses of counsel to the
Indemnified Party shall be reimbursed on a current basis by the Indemnifying Party as if such
expenses are a liability of the Indemnifying Party.

	 	 	 	Section 12.6. Exclusive Remedy.

Except as otherwise provided in Sections 3.2(b), 6.4 or 9.2, the rights, remedies and
obligations of the Buyer Indemnitees and the Seller Indemnitees set forth in this Article XII will
be the exclusive rights, remedies and obligations of such Persons after the Closing with respect to
all post-Closing claims relating to this Agreement, the events giving rise to this Agreement and
the transactions provided for herein or contemplated hereby or thereby. No Proceeding for
termination or rescission, or claiming repudiation, of this Agreement may be brought or maintained
by either party against the other following the Closing Date no matter how severe, grave or
fundamental any breach, default or nonperformance may be by one party. Accordingly, the parties
hereby expressly waive and forego any and all rights they may possess to bring any such Proceeding.

	 	 	 	Section 12.7. Waiver and Release.

Buyer, on behalf of itself and each other Buyer Indemnitee, hereby forever waives, relieves,
releases and discharges the Seller Indemnitees and their successors and assigns from any and all
rights, liabilities, Proceedings (including future Proceedings) and Losses of any Buyer Indemnitee,
whether known or unknown at the Closing Date, which any Buyer Indemnitee has or incurs, or may in
the future have or incur, arising out of or related to any Assumed Liability.

	Section 13.3.
	 	Assignment.

This Agreement may not be assigned, by operation of law or otherwise, by any party hereto
without the prior written consent of the other party hereto, such consent not to be unreasonably
withheld; provided, however, in the event of any such assignment by a party by operation of law
without the consent of the other party as required above, such other party may consent to such
assignment after it has occurred and, in such event, this Agreement and all the provisions hereof
shall be binding upon the Person receiving such assignment by operation of law. Notwithstanding
the foregoing, (a) Seller may assign all or part of its rights or delegate all or part of its
duties under this Agreement, without the prior written consent of Buyer, to a qualified
intermediary chosen by Seller to structure all or part of the transactions contemplated hereby as a
like-kind exchange of property covered by Section 1031 of the IRC and (b) Buyer may assign all or
part of its rights, but not its obligations, under this Agreement to a wholly owned subsidiary.

	 	 	 	Section 13.4. Successor Bound.

Subject to the provisions of Section 13.3, this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and permitted assigns.

	 	 	 	Section 13.5. Governing Law.

The validity, performance, and enforcement of this Agreement and all Related Documents, unless
expressly provided to the contrary, shall be governed by the laws of the State of New York without
giving effect to the principles of conflicts of law of such state.

	 	 	 	Section 13.6. Cooperation.

Each of the parties hereto agrees to use its commercially reasonable efforts to take or cause
to be taken all action, and to do or cause to be done all things necessary, proper or advisable
under applicable laws, regulations or otherwise, to consummate and to make effective the
transactions contemplated by this Agreement, including the timely performance of all actions and
things contemplated by this Agreement to be taken or done by each of the parties hereto.

	 	 	 	Section 13.7. Construction of Agreement.

The terms and provisions of this Agreement represent the results of negotiations between Buyer
and Seller, each of which has been represented by counsel of its own choosing, and neither of which
has acted under duress or compulsion, whether legal, economic or otherwise. Accordingly, the terms
and provisions of this Agreement shall be interpreted and construed in accordance with their usual
and customary meanings, and Buyer and Seller hereby waive the application in connection with the
interpretation and construction of this Agreement of any rule of law to the effect that ambiguous
or conflicting terms or provisions contained in this Agreement shall be interpreted or construed
against the party whose attorney prepared the executed draft or any earlier draft of this
Agreement. It is understood and agreed that neither the specification of any dollar amount in the
representations and warranties contained in this Agreement nor the inclusion of any specific item
in the Schedules or Exhibits is intended to imply that such amounts or higher or lower amounts, or
the items so included or other items, are or are not material, and none of the parties shall use
the fact of the setting of such amounts or the fact of any inclusion of any such item in the
Schedules or Exhibits in any dispute or controversy between the parties as to whether any
obligation, item or matter is or is not material for purposes hereof. The word “including” in this
Agreement shall mean including without limitation. Words in the singular shall be held to include
the plural and vice versa and words of one gender shall be held to include the other genders as the
context requires. The terms “hereof,” “herein,” and “herewith” and words of similar import shall,
unless otherwise stated, be construed to refer to this Agreement as a whole (including all of the
Schedules and Exhibits hereto) and not to any particular provision of this Agreement, and Article,
Section, paragraph, Exhibit and Schedule references are to the Articles, Sections, paragraphs,
Exhibits and Schedules to this Agreement unless otherwise specified.

	 	 	 	Section 13.8. Publicity.

Neither party hereto shall issue, make or cause the publication of any press release or other
announcement with respect to this Agreement or the transactions contemplated hereby, or otherwise
make any disclosures relating thereto, without the consent of the other party, such consent not to
be unreasonably withheld or delayed; provided, however, that such consent shall not be required
where such release or announcement is required by applicable law or the rules or regulations of a
securities exchange, in which event the party so required to issue such release or announcement
shall endeavor, wherever possible, to furnish an advance copy of the proposed release to the other
party.

	 	 	 	Section 13.9. Waiver.

Except as otherwise expressly provided in this Agreement, neither the failure nor any delay on
the part of any party to exercise any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise or waiver of any such right, power or privilege
preclude any other or further exercise thereof, or the exercise of any other right, power or
privilege available to each party at law or in equity.

	 	 	 	Section 13.10. Parties in Interest.

This Agreement (including the documents and instruments referred to herein) is not intended to
confer upon any Person, other than the parties hereto and their successors and permitted assigns,
any rights or remedies hereunder provided, however, that the indemnification provisions in Article
XII shall inure to the benefit of the Buyer Indemnitees and the Seller Indemnitees as provided
therein.

	 	 	 	Section 13.11. Section and Paragraph Headings.

The section and paragraph headings in this Agreement are for reference purposes only and shall
not affect in any way the meaning or interpretation of this Agreement.

	 	 	 	Section 13.12. Amendment.

This Agreement may be amended only by an instrument in writing executed by the parties hereto.

	 	 	 	Section 13.13. Entire Agreement.

This Agreement, the Exhibits and Schedules hereto and the documents specifically referred to
herein and the Confidentiality Agreement constitute the entire agreement, understanding,
representations and warranties of the parties hereto, and supersede all prior agreements, both
written and oral, between Buyer and Seller. All Exhibits and Schedules annexed hereto or referred
to herein are hereby incorporated in and made a part of this Agreement as if set forth in full
herein. Disclosure of any fact or item in any Schedule referenced by a particular paragraph or
Section in this Agreement shall, should the existence of the fact or item or its contents be
relevant to any other paragraph or Section, be deemed to be disclosed with respect to that other
paragraph or Section whether or not any explicit cross-reference appears therein; provided,
however, that notwithstanding the foregoing, no disclosures shall be deemed to be disclosed on
Schedule 5.20 except for such disclosures explicitly set forth thereon or explicitly
incorporated by reference into Schedule 5.20.

	 	 	 	Section 13.14. Counterparts.

This Agreement may be executed in multiple counterparts, each of which shall be deemed an
original, and all of which together shall constitute one and the same instrument.

	 	 	 	Section 13.15. Severability.

If any term or other provision of this Agreement is invalid, illegal or incapable of being
enforced by any rule of law or public policy, all other conditions and provisions of this Agreement
shall nevertheless remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner materially adverse to any party.
Upon such determination that any term or other provision is invalid, illegal or incapable of being
enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in an acceptable manner to the end that
transactions contemplated hereby are fulfilled to the greatest extent possible.

	 	 	 	Section 13.16. Consent to Jurisdiction.

The parties hereby irrevocably submit to the exclusive jurisdiction of the courts of the State
of New York located in the Borough of Manhattan and the federal courts of the United States of
America located in the Southern District of the State of New York over any dispute arising out of
or relating to this Agreement or any of the transactions contemplated hereby, and each party
irrevocably agrees that all claims in respect of such dispute or proceeding shall be heard and
determined in such courts. The parties hereby irrevocably waive, to the fullest extent permitted
by applicable law, any objection which they may now or hereafter have to the venue of any dispute
arising out of or relating to this Agreement or any of the transactions contemplated hereby brought
in such court or any defense of inconvenient forum for the maintenance of such dispute. Each party
agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by applicable law.
