Exhibit 10.1

POSTROCK ENERGY CORPORATION

MANAGEMENT INCENTIVE PROGRAM

	I.	 	GENERAL

     PostRock Energy Corporation, a Delaware corporation (the “Company” or “PostRock”), adopted the
PostRock 2010 Long-Term Incentive Plan (the “Plan”) in part to allow eligible employees of PostRock
and its subsidiaries and non-employee directors of PostRock to strengthen their commitment to the
success of PostRock, to stimulate their efforts on PostRock’s behalf and to assist PostRock and its
subsidiaries in attracting new employees and non-employee directors and retaining existing
employees and non-employee directors. The Plan is also intended to optimize the profitability and
growth of PostRock through incentives which are consistent with PostRock’s goals, to provide
incentives for excellence in individual performance, and to promote teamwork. The Plan provides
for grants of certain equity-based awards and cash awards (“Cash Awards”).

     Pursuant to the Cash Awards’ feature of the Plan, the Board of Directors has designated a
group of employees who may be eligible to receive Cash Awards under the Plan, established the
applicable performance goals relating to such Cash Awards and adopted this Management Incentive
Program (“MIP”). Unless otherwise defined herein, capitalized terms that are used herein shall
have the meanings assigned to such terms in the Plan. All provisions of the MIP and the rights of
the Grantee’s are subject in all respects to the provisions of the Plan and the powers of the Board
of Directors therein provided.

	II.	 	DEFINITIONS

	 	A.	 	“Approval of the Board” or “Approved by the Board” means the initial approval
by the Compensation Committee and, except with respect to certain approvals required
by Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162(m)”)
to be completed solely by the Compensation Committee, the subsequent recommendation by
the Compensation Committee to, and approval by, the Board of Directors.
	 
	 	B.	 	“Base Salary” equals the base annual salary for the Fiscal Year for which the
Cash Award is calculated as established by the Compensation Committee within the first
90 days of each Fiscal Year. Subsequent increases in base salary during a performance
period will not be taken into account when determining the final Cash Award payment,
if any, under the MIP.
	 
	 	C.	 	“Board of Directors” means the Board of Directors of the Company.
	 
	 	D.	 	“Chief Executive Officer” means the Chief Executive Officer of the Company.

1 of 5

 

	 	E.	 	“Compensation Committee” means the Compensation Committee of the Board of
Directors.
	 
	 	F.	 	“Fiscal Year” means the Company’s Fiscal Year beginning January 1 and ending
December 31.
	 
	 	G.	 	“Percentage of Goals Achieved” shall be based on the weighted average of the
performance criteria based on the Company’s performance during 2010 as calculated in
accordance with Schedule 2.
	 
	 	H.	 	“Performance Goals” for each Fiscal Year are the financial and operational
goal(s) established by the Board of Directors as applied to Grantees in the position
levels outlined in Schedule 3 hereto. Applicable Performance Goals are set forth on
Schedule 2 hereto and are based on or related to one or more of those Performance
Goals set forth in Section 10.2 of the Plan.

	III.	 	EMPLOYEES COVERED BY THE PROGRAM

	 	 	Those employees listed on Schedule 3 and those employees who are subsequently determined by
the Chief Executive Officer and the Compensation Committee to participate in the MIP (each
such employee, a “Grantee”) shall be eligible to participate in the MIP.

	IV.	 	CASH AWARD

	 	 	A Grantee in the MIP may be entitled to a Cash Award calculated as determined in accordance
with the formula Approved by the Board as set forth herein.

	V.	 	PARTICIPANT BONUS COMPOSITION

	 	 	The composition of the bonuses for each Fiscal Year eligible to be paid under the MIP will
be determined and Approved by the Board. Although the Company anticipates that all Cash
Awards, if any, will be settled in cash, the Company reserves the right to settle any Cash
Awards in the form of Company Shares in accordance with the Plan.

	VI.	 	COMPUTATION AND DISBURSEMENT OF FUNDS

	 	A.	 	A Grantee in the MIP may be entitled to a Cash Award computed as the product
of (i) the Grantee’s Base Salary times (ii) the percentage listed for such Grantee’s
Level on Schedule 1 based on the Percentage of Goals Achieved.

	 	B.	 	No Cash Award will be paid if the “Percentage of Goals Achieved” is less than
60%. No additional amounts will be paid in excess of those reflected on Schedule 1 if
the Percentage of Goals Achieved is more than 150%.

2 of 5

 

	 	C.	 	Except as otherwise provided herein, no Cash Award may be paid to a Grantee
unless Grantee is employed by the Company or a subsidiary thereof on the payment date
for such Cash Award.
	 
	 	D.	 	As soon as practicable after the close of the Fiscal Year, but no later than
thirty (30) days after the Company’s receipt of the annual audit, the Chief Financial
Officer of the Company shall calculate the financial and operational performance
measures and the proposed payout under the MIP based upon the achievement of the
financial and operational performance measures. The proposed payout shall be presented
to the Chief Executive Officer and, subject to the Chief Executive Officer’s or
Compensation Committee’s discretionary ability to reduce the amount or totally
eliminate the Cash Award, Approved by the Board. Neither the Chief Executive Officer
nor the Board of Directors shall have any ability to increase the amount of a Cash
Award.
	 
	 	E.	 	If a Cash Award is approved, payment of the Cash Award shall be made as soon
as practicable after, but in no later than sixty (60) days after, the Company’s
receipt of the annual audit, provided, however, that in all events such Cash Award (if
any) shall be paid during the Fiscal Year immediately following the close of the
Fiscal Year for which the payout relates. Accordingly, Cash Awards for the 2010
Fiscal Year shall be paid during the 2011 Fiscal Year.
	 
	 	F.	 	As Approved by the Board, if, before payment of any Cash Award, a Grantee (i)
dies, (ii) becomes permanently disabled, (iii) enters military service, (iv) takes an
approved leave of absence, (v) is appointed or elected to public office, or (vi) is
terminated due to position elimination, then, based on the actual level of goal
achievement and provided that the Percentage of Goals Achieved is above 60%:

	 	(a)	 	the Grantee may be entitled to a payment of the full amount
of the Cash Award if such separation occurs after the end of the Fiscal Year
to which such Cash Award relates; or
	 
	 	(b)	 	the Grantee may be entitled to a payment of a partial
amount of the Cash Award based on the number of days during the Fiscal Year
the Grantee performed services for the Company or a subsidiary thereof
divided by 365, if such separation occurred before the end of the Fiscal Year
for which such Cash Award relates; provided, however, that the Grantee must
have been an active employee for a minimum of 90 consecutive calendar days
during such Fiscal Year.

	 	 	 	The foregoing notwithstanding, any payment of any Cash Awards under this Subsection
F shall be made in accordance with the general payment provisions in this Section
VI (that is, during the Fiscal Year immediately following the Fiscal Year for which
the payout relates).

3 of 5

 

	 	G.	 	Any payment made under the MIP will be made to the Grantee. In the event of
a Grantee’s death, any Cash Award payable will be paid to the Grantee’s designated
beneficiaries on file with the Company or, in the absence of such designation, paid to
the Grantee’s estate.

	 	H.	 	All Cash Awards shall be reduced by amounts required to be withheld for any
and all federal, state or local income or employment taxes at the time payments are
made.

	VII.	 	CHANGES TO TARGET

	 	 	Except with respect to any “covered employee” (as that term is defined under Section
162(m)) where a change to any performance measures, target and payout ranges would cause
the payment of a Cash Award not to be deductible under Section 162(m), with the Approval of
the Board, the Company may, at any time prior to the final determination of awards,
consider changes to the performance measures, targets, and payout ranges used for incentive
purposes, if, in the judgment of the Company, such change(s) is/are desirable in the
interests of equitable treatment of the Grantees and the Company as a result of
extraordinary or non-recurring events, changes in applicable accounting rules or
principles, changes in the Company’s methods of accounting, changes in applicable law, or
changes due to consolidation, acquisitions, or reorganization. With the Approval of the
Board, the Chief Executive Officer may implement such changes(s) for immediate
incorporation into the MIP.

	 	 	Grantees hired, or who otherwise become eligible to participate hereunder during the course
of a Fiscal Year and who are employed through the end of such Fiscal Year shall be eligible
for a pro-rated award based on their Base Salary during such Fiscal Year and length of
eligible service prior to the end of the Fiscal Year so long as the Grantee was in a bonus
eligible position for at least 90 days.

	VIII.	 	FORFEITURE OF BONUS

	 	 	Except as provided in Section VI, no Grantee who ceases to be an employee of the Company or
any subsidiary thereof before the payment date of a Cash Award shall be entitled to any
Cash Award under the MIP for such Fiscal Year unless the Chief Executive Officer, in
consultation with the Compensation Committee or Board of Directors, determines otherwise.

	IX.	 	NO EMPLOYMENT CONTRACT; FUTURE PLANS

	 	 	Participation in the MIP shall not confer upon any Grantee any right to continue in the
employ of the Company nor interfere in any way with the right of the Company to terminate
any Grantee’s employment at any time. The Company is under no obligation to continue the
MIP in future Fiscal Years.

4 of 5

 

	X.	 	AMENDMENT OR TERMINATION

	 	 	With the Approval of the Board, the Company may at any time, or from time to time,
(a) amend, alter or modify the provisions of the MIP and the Plan, (b) terminate the MIP or
the Plan, or (c) terminate the participation of a Grantee or group of Grantees in the MIP
or the Plan; provided, however, that in the event of the termination of the MIP or the Plan
or a termination of the participation of a Grantee or group of Grantees, the Company shall
provide notification to the affected Grantees, as soon as practicable, outlining the extent
of the MIP or Plan termination or Grantee termination in the MIP and the calculation of the
partial awards, if any, to be granted to the affected Grantee(s) for the portion of the
Fiscal Year during which such Grantees participated in the MIP, in a manner Approved by the
Board and in which the Company, in its sole judgment, determines to be equitable to such
Grantees and the Company. For the avoidance of doubt, the Company may, at any time,
terminate the MIP without having any obligation to make any full or partial payments to any
Grantee.

	XI.	 	GENERAL PROVISIONS

	 	A.	 	No right under the MIP or the Plan shall be assignable, either voluntarily or
involuntarily, by way of encumbrance, pledge, attachment, level or charge of any
nature (except as may be required by state or federal law).

	 	B.	 	Nothing in the MIP or Plan shall require the Company to segregate or set
aside any funds or other property for the purpose of paying any portion of a Cash
Award. No Grantee, beneficiary or other person shall have any right, title or interest
in any amount awarded under the MIP or the Plan before the payment date for the Cash
Award, or in any property of the Company or its subsidiaries.

otherwise or (b) directly or indirectly acquires (in one transaction or as the most recent

Business Day) plus 1%.

“A.M. Best Rating” means, as to any insurance company, its financial strength rating assigned

ARTICLE II

THE LETTER OF CREDIT FACILITY

2.1 Issuance of Letters of Credit. (a) From and after the date hereof to but
excluding the Letter of Credit Availability Termination Date, the Issuer agrees, upon the terms
and conditions set forth in this Agreement, to issue at the request and for the account of the
Borrower, one or more Letters of Credit for the account of the Borrower (x) to support the
obligations of Wholly-Owned Subsidiaries of the Borrower with respect to specific

 

- 16 -

 

syndicates at the Society of Lloyd’s (the Letters of Credit issued under this clause (x)
being called the “Lloyd’s Letters of Credit”) and (y) to support other obligations,
provided that the aggregate face amount of all outstanding Letter of Credit Obligations with
respect to this clause (y) does not at any time exceed the lesser of (A) the Letter of Credit
Commitment and (B) $10,000,000; provided, however, that the Issuer shall not be
under any obligation to issue, and shall not issue, any Letter of Credit if: (i) any order,
judgment or decree of any governmental authority or other regulatory body with jurisdiction over
the Issuer shall purport by its terms to enjoin or restrain such Issuer from issuing such Letter
of Credit, or any law or governmental rule, regulation, policy, guideline or directive (whether
or not having the force of law) from any governmental authority or other regulatory body with
jurisdiction over the Issuer shall prohibit, or request that the Issuer refrain from, the
issuance of Letters of Credit in particular or shall impose upon the Issuer with respect to any
Letter of Credit any restriction or reserve or capital requirement (for which the Issuer is not
otherwise compensated) or any unreimbursed loss, cost or expense which was not applicable, in
effect and known to the Issuer as of the date of this Agreement and which the Issuer in good
faith deems material to it, (ii) one or more of the conditions to such issuance contained in
Section 4.2 is not then satisfied or (iii) after giving effect to such issuance, the
aggregate outstanding amount of the Letter of Credit Obligations would exceed the Letter of
Credit Commitment. For purposes of clause (iii) of the immediately preceding sentence,
at any time there is a Defaulting Lender, the Letter of Credit Commitment shall be automatically
reduced by an amount equal to the remainder of (A) such Defaulting Lender’s pro-rata share of
the Letter of Credit Commitment minus (B) such Defaulting Lender’s pro-rata share of the Letter
of Credit Obligations then outstanding; provided, however, the Letter of Credit
Commitment shall be restored if either (i) such Defaulting Lender provides cash collateral to
the Agent for the account of such Defaulting Lender pursuant to Section 10.11 in the
amount of such Defaulting Lender’s pro-rata share of the Letter of Credit Commitment or (ii) the
Borrower has entered into satisfactory arrangements with the Issuer to eliminate the Issuer’s
risk with respect to such Defaulting Lender, it being agreed that such satisfactory arrangements
may include collateral or the charging of a fee and the Lenders agree that any such collateral
or fee shall belong solely to the Issuer and shall not be subject to the sharing provisions of
this Agreement. Letters of Credit shall be denominated, at the Borrower’s option, in either
Dollars or Pounds.

(b) In no event shall: (i) the aggregate amount of the Letter of Credit Obligations at
any time exceed the Letter of Credit Commitment or (ii) the expiration date of any Letter of
Credit (other than the Letters of Credit identified on Schedule 2.1 hereto) or the date for
payment of any draft presented thereunder and accepted by the Issuer, be later than (x) the
date one (1) year after the effective date of such Letter of Credit or (y) in the case of
the Lloyd’s Letters of Credit, four (4) years after the date of the related Expiry Notice.
The Issuer shall not permit the renewal or extension of any Letter of Credit at any time (A)
during the continuation of a Default or Unmatured Default or (B) after the Letter of Credit
Availability Termination Date.

(c) The Issuer (i) shall issue an Expiry Notice on the Letter of Credit Availability
Termination Date and (ii) may, and upon the request of the Required Lenders

 

- 17 -

 

shall, issue an Expiry Notice when a Default has occurred and is continuing;
provided, however, that upon the occurrence of an Unmatured Default pursuant
to Sections 7.6 and 7.7, the Issuer shall immediately issue an Expiry
Notice.

(d) The Borrower agrees that, if at any time as a result of reductions in the Letter of
Credit Commitment pursuant to Section 2.3 or otherwise the aggregate balance of the
Letter of Credit Obligations exceeds the Letter of Credit Commitment, the Borrower shall
cash collateralize the Letter of Credit Obligations by depositing, into a Collateral
Account, Cash Collateral Investments with a Collateral Value equal to the product of one
hundred and three percent (103%) of the amount as may be necessary to eliminate such excess.

(e) The Letters of Credit identified on Schedule 2.1 hereto (the “Existing
Letters of Credit”) which are issued and outstanding under the Existing Credit Agreement
shall, upon satisfaction of the conditions set forth in Article IV hereto,
automatically and without further action on the part of the Agent, the Issuer, the Lenders
or the Borrower be deemed Letters of Credit issued under this Agreement.

(f) For purposes of determining usage and availability under this Section 2.1,
when a Letter of Credit is issued in Pounds, such Pounds will be converted to Dollars upon
issuance, upon the proposed issuance of any other Letter of Credit and at the end of each
calendar quarter and at any time thereafter as requested by the Agent or any Lender
(including the Issuer) and such determination shall be made by the Agent in its sole
determination based upon the spot exchange rate between Dollars and Pounds as quoted by the
Agent as of such date of determination. Notwithstanding any other provisions of this
Agreement, if at any time, after giving effect to the conversion of Pounds into Dollars as
set forth above, the aggregate face amount of all outstanding Letters of Credit is greater
than the Letter of Credit Commitment (“Conversion Differential”), then the Borrower
shall cash collateralize such Conversion Differential by depositing into a Collateral
Account Cash Collateral Investments with a Collateral Value equal to the product of one
hundred and three percent (103%) of the Conversion Differential.

(g) At the request of the Borrower, Letters of Credit may be issued with any
Wholly-Owned Subsidiary of the Borrower as a co-applicant, so long as the Borrower is also a
co-applicant under the applicable Reimbursement Agreement. The fact that such Subsidiary is
an applicant shall not affect the obligations of the Borrower with respect to such Letters
of Credit hereunder or under any Facility Document in any way. Any Reimbursement Agreement
for a Letter of Credit with respect to which such Subsidiary is a co-applicant shall include
language substantially similar to that set forth in Exhibit C or otherwise
acceptable to the Agent.

2.2 Participating Interests. Immediately upon the issuance by the Issuer of a
Letter of Credit in accordance with Section 2.5 (and with respect to the Letters of
Credit identified on Schedule 2.1 hereto, upon satisfaction of the conditions set forth
in Article IV hereof), each Lender shall be deemed to have irrevocably and
unconditionally purchased and

 

- 18 -

 

received from the Issuer, without recourse, representation or warranty, an undivided
participation interest equal to its pro-rata share of the Letter of Credit Commitment (including
as may be adjusted pursuant to Section 2.1(a)) of the face amount of such Letter of
Credit and each draw paid by the Issuer thereunder; provided, however, that
during any period in which there is a Defaulting Lender, for purposes of computing the amount of
the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in
Letters of Credit pursuant to this Section 2.2, the pro-rata share of each
non-Defaulting Lender shall be computed without including such Defaulting Lender’s share of the
Letter of Credit Commitment; provided, further, that once such Defaulting Lender
shall cease to be a Defaulting Lender or has provided cash collateral to the Agent pursuant to
Section 10.11, the pro-rata share of each Lender shall be recalculated including all
Lenders’ share of the Letter of Credit Commitment. Notwithstanding the foregoing, under no
circumstances shall any Lender be deemed to have purchased a participation interest in excess of
such Lender’s commitment amount. Each Lender’s obligation to pay its proportionate share of all
draws under the Letters of Credit, absent gross negligence or willful misconduct by the Issuer
in honoring any such draw, shall be absolute, unconditional and irrevocable and in each case
shall be made without counterclaim or set-off by such Lender.

2.3 Reductions in Letter of Credit Commitment. (a) The Borrower may permanently
reduce the Letter of Credit Commitment in whole, or in part ratably among the Lenders in
integral multiples of $5,000,000, upon at least five (5) Business Days’ written notice to the
Agent, which notice shall specify the amount of such reduction; provided,
however, that the amount of the Letter of Credit Commitment may not be reduced below the
aggregate amount of the outstanding Letter of Credit Obligations.

(b) At any time a Lender is a Designated Lender, the Borrower may terminate in full the
commitment of such Designated Lender by giving notice to such Designated Lender and the
Agent; provided that (i) at the time of such termination, no Default or Unmatured
Default exists (or the Required Lenders consent to such termination) and (ii) concurrently
with such termination, (A) the Letter of Credit Commitment shall be reduced by the
commitment amount of such Designated Lender (it being understood that the Borrower may not
terminate the commitment of a Designated Lender if, after giving effect to such termination,
the Letter of Credit Obligations would exceed the reduced Letter of Credit Commitment), (B)
the Borrower shall pay all amounts owed to such Designated Lender hereunder and (C) the
Agent shall return to such Lender any cash collateral held for the account of such Lender
pursuant to Section 2.9(d). The termination of the commitment of a Defaulting
Lender pursuant to this Section 2.3 shall not be deemed to be a waiver of any right
that (x) the Borrower, the Agent, the Issuer or any other Lender may have against such
Defaulting Lender or (y) such Defaulting Lender may have against the Borrower based on the
estimate described in clause (B) of the preceding sentence.

2.4 Reimbursement Obligations. (a) The Borrower agrees to pay to the Issuer of a
Letter of Credit (i) on each date that any amount is drawn under each Letter of Credit (or, if
any draw is paid by the Issuer after 3:00 p.m. (New York time) on such date, on
the next

 

- 19 -

 

succeeding Business Day) a sum (and interest on such sum as provided in clause
(ii) below) equal to the amount so drawn plus all other charges and expenses with respect
thereto specified in Section 2.9 or in the applicable Reimbursement Agreement and (ii)
interest on any and all amounts remaining unpaid under this Section 2.4 until payment in
full at the rate per annum, computed for actual days elapsed based on a 365 or 366 day year, as
applicable, equal to (A) the Alternate Base Rate plus the Applicable Margin for such day for the
first two days following the due date of any Reimbursement Obligations and (B) the Alternate
Base Rate plus the Applicable Margin for such day plus 2% per annum thereafter. The Borrower
agrees to pay to the Issuer the amount of all Reimbursement Obligations owing in respect of any
Letter of Credit immediately when due, under all circumstances, including, without limitation,
any of the following circumstances: (w) any lack of validity or enforceability of this
Agreement or any of the other Facility Documents, (x) the existence of any claim, set-off,
defense or other right which the Borrower may have at any time against a beneficiary named in a
Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such
transferee may be acting), any Lender or any other Person, whether in connection with this
Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated
transactions (including any underlying transaction between the Borrower and the beneficiary
named in any Letter of Credit), (y) the validity, sufficiency or genuineness of any document
which the Issuer has determined in good faith complies on its face with the terms of the
applicable Letter of Credit, even if such document should later prove to have been forged,
fraudulent, invalid or insufficient in any respect or any statement therein shall have been
untrue or inaccurate in any respect or (z) the surrender or impairment of any security for the
performance or observance of any of the terms hereof.

(b) Notwithstanding any provisions to the contrary in any Reimbursement Agreement, the
Borrower agrees to reimburse the Issuer for amounts which the Issuer pays under such Letter
of Credit no later than the time specified in this Agreement. If the Borrower does not pay
any such Reimbursement Obligations when due at any time prior the Letter of Credit
Termination Date, such Reimbursement Obligations, if in Pounds, shall be deemed to have been
converted into the equivalent amount of Dollars on the date due based upon the spot rate of
exchange between Dollars and Pounds as determined by the Agent on the Reuters WRLD Page as
of the time of determination on such date. In the event that such rate does not appear on
any Reuters WRLD Page, the exchange rate shall be determined by reference to such other
publicly available service for displaying exchange rates as may be agreed upon by the Agent
and the Borrower, or, in the absence of such an agreement, such exchange rate shall instead
be the arithmetic average of the spot rates of exchange of the Agent in London at or about
such time between Dollars and Pounds for delivery two Business Days later; provided
that if at the time of any such determination, for any reason, no such spot rate is being
quoted, the Agent may use any reasonable method it deems appropriate to determine such rate
and such determination shall be presumed correct absent manifest error.

(c) If the Issuer makes a payment on account of any Letter of Credit and is not
concurrently reimbursed therefor by the Borrower, then as promptly as practical during
normal banking hours on the date of its receipt of such notice or, if not practicable on

 

- 20 -

 

such date, not later than noon (New York time) on the Business Day immediately
succeeding such date of notification, each Lender shall deliver to the Agent for the account
of the Issuer, in immediately available funds, the purchase price for such Lender’s interest
in such unreimbursed Reimbursement Obligations, which shall be an amount equal to such
Lender’s pro-rata share of such payment. Each Lender shall, upon demand by the Issuer, pay
the Issuer interest on such Lender’s pro-rata share of such draw from the date of payment by
the Issuer on account of such Letter of Credit until the date of delivery of such funds to
the Issuer by such Lender at a rate per annum, computed for actual days elapsed based on a
360-day year, equal to the Federal Funds Effective Rate on the amount of the unreimbursed
Reimbursement Obligations, if in Dollars, or the equivalent amount of Dollars calculated in
the manner provided in paragraph (b), if in Pounds, for such period;
provided, that such payments shall be made by the Lenders only in the event and to
the extent that the Issuer is not reimbursed in full by the Borrower for interest on the
amount of any draw on the Letters of Credit.

(d) At any time after the Issuer has made a payment on account of any Letter of Credit
and has received from any other Lender such Lender’s pro-rata share of such payment, such
Issuer shall, forthwith upon its receipt of any reimbursement (in whole or in part) by the
Borrower for such payment, or of any other amount from the Borrower or any other Person in
respect of such payment (including, without limitation, any payment of interest or penalty
fees and any payment under any collateral account agreement of the Borrower or any Facility
Document but excluding any transfer of funds from any other Lender pursuant to
Section 2.4(c)), transfer to such other Lender such other Lender’s ratable share of
such reimbursement or other amount; provided, that interest shall accrue for the
benefit of such Lender from the time such Issuer has made a payment on account of any Letter
of Credit; provided, further, that in the event that the receipt by the
Issuer of such reimbursement or other amount is found to have been a transfer in fraud of
creditors or a preferential payment under the United States Bankruptcy Code or is otherwise
required to be returned, such Lender shall promptly return to the Issuer any portion thereof
previously transferred by the Issuer to such Lender, but without interest to the extent that
interest is not payable by the Issuer in connection therewith.

(e) All payments in respect of Reimbursement Obligations shall be in Dollars.

2.5 Procedure for Issuance. Prior to the issuance of each new Letter of Credit and
as a condition of such issuance, the Borrower shall deliver to the Issuer (with a copy to the
Agent) a Reimbursement Agreement signed by the Borrower, together with such other documents or
items as may be required pursuant to the terms thereof, and the proposed form and content of
such Letter of Credit shall be reasonably satisfactory to the Issuer. Each Letter of Credit
shall be issued no earlier than two (2) Business Days after delivery of the foregoing documents,
which delivery may be by the Borrower to the Issuer by telecopy, telex or other electronic means
followed by delivery of executed originals within five (5) days thereafter. The documents so
delivered shall be in compliance with the requirements set forth in Section 2.1(b), and
shall specify therein (a) the stated amount of the Letter of Credit requested, (b) the effective
date of issuance of such requested Letter of Credit, which shall be

 

- 21 -

 

a Business Day, (c) the date on which such requested Letter of Credit is to expire, which
shall be no later than one (1) year from the date of issuance of such Letter of Credit or in the
case of a Lloyd’s Letter of Credit, four years from the date of the related Expiry Notice, (d)
whether the Letter of Credit is to be denominated in Dollars or Pounds and (e) the aggregate
amount of Letter of Credit Obligations which are outstanding and which will be outstanding after
giving effect to the requested Letter of Credit issuance. The delivery of the foregoing
documents and information shall constitute an “Issuance Request” for purposes of this
Agreement. Subject to the terms and conditions of Section 2.1 and provided that the
applicable conditions set forth in Section 4.2 hereof have been satisfied, the Issuer
shall, on the requested date, issue a Letter of Credit on behalf of the Borrower in accordance
with the Issuer’s usual and customary business practices. In addition, any amendment of an
existing Letter of Credit shall be deemed to be an issuance of a new Letter of Credit and shall
be subject to the requirements set forth above. The Issuer shall give the Agent prompt written
notice of the issuance of any Letter of Credit.

2.6 Nature of the Lenders’ Obligations. (a) As between the Borrower and the
Lenders, the Borrower assumes all risks of the acts and omissions of, or misuse of the Letters
of Credit by, the respective beneficiaries of the Letters of Credit; provided,
however, that the Borrower may have a claim against the Issuer and the Issuer may be
liable to the Borrower, to the extent, but only to the extent, of any direct (as opposed to
consequential or exemplary) damages suffered by the Borrower which the Borrower proves were
caused by the Issuer’s willful misconduct or gross negligence in determining whether documents
presented under a Letter of Credit comply with the terms of such Letter of Credit. In
furtherance and not in limitation of the foregoing, the Lenders shall not be responsible for:
(i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document
submitted by any party in connection with the application for an issuance of a Letter of Credit,
even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate,
fraudulent or forged, (ii) the validity or sufficiency of any instrument transferring or
assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or
ineffective for any reason, (iii) the failure of the beneficiary of a Letter of Credit to comply
fully with conditions required to be satisfied by any Person other than the Issuer in order to
draw upon such Letter of Credit, (iv) errors, omissions, interruptions or delays in transmission
or delivery of any messages, by mail, cable, telegraph, telex or otherwise, (v) errors in the
interpretation of technical terms, (vi) the misapplication by the beneficiary of a Letter of
Credit of the proceeds of any drawing under such Letter of Credit or (vii) any consequences
arising from causes beyond control of the Issuer.

(b) In furtherance and extension and not in limitation of the specific provisions
hereinabove set forth, any action taken or omitted by the Issuer under or in connection with
the Letters of Credit or any related certificates, if taken or omitted in good faith, shall
not put the Agent or any Lender under any resulting liability to the Borrower or relieve the
Borrower of any of its obligations hereunder to the Issuer or any such Person.

 

- 22 -

 

2.7 Notification of Issuance Requests. Promptly after receipt thereof, the Agent
will notify each Lender of the contents of each Issuance Request received by it hereunder.

2.8 Cash Collateral for Letters of Credit. On the Letter of Credit Availability
Termination Date, the Borrower shall pledge and deliver to the Agent, for the benefit of the
Secured Parties, Cash Collateral Investments in a Collateral Account with a Collateral Value
equal to the product of one hundred and three percent (103%) of the amount equal to the
following percentage of the Letter of Credit Obligations outstanding from time to time during
the following periods:

	 	 	 	 	 
	 	 	Percentage of Letter of Credit	 
	Period	 	Obligations Collateralized	 
	 
	 	 	 	 
	Letter of Credit Availability Termination Date to but not
including the date nine (9) months after the Letter of Credit
Availability Termination Date
	 	 	50	%
	 
	 	 	 	 
	the date nine (9) months after the Letter of Credit Availability
Termination Date, or an earlier date at the Borrower’s option, and at all
times thereafter
	 	 	100	%

2.9 Fees.

(a) Unused Fee. The Borrower agrees to pay to the Agent for the account of
each Lender with respect to its Letter of Credit Participation Amount an unused fee at a
rate per annum equal to the Applicable Unused Fee Rate on the daily unused portion of such
Lender’s Letter of Credit Participation Amount from the Closing Date to and including the
Letter of Credit Availability Termination Date, calculated with respect to actual days
elapsed on the basis of a 360-day year and payable on each Payment Date hereafter and on the
Letter of Credit Availability Termination Date or, if later, upon receipt of a bill from the
Agent. Accrued and unpaid unused fees under the Existing Credit Agreement shall be paid on
the Closing Date or, if later, upon receipt of a bill from the Agent.

(b) Letter of Credit Fronting Fee. The Borrower hereby agrees to pay to the
Agent, for the account of the Issuer, a letter of credit fronting fee with respect to each
Letter of Credit from and including the date of issuance thereof (or, with respect to the
Letters of Credit identified on Schedule 2.1, the date on which such Letters of
Credit are deemed issued under this Agreement pursuant to Section 2.1(d)) until the
date such Letter of Credit is fully drawn, canceled or expired, in an amount equal to the
rate provided in the Fee Letter of the aggregate initial face amount of such Letter of
Credit, calculated with respect to actual days elapsed on the basis of a 360-day year and
payable quarterly in arrears on each Payment Date in each year and upon the expiration,
cancellation or utilization in full of such Letter of Credit. In addition to the foregoing,
the Borrower
agrees to pay the Issuer any other fees customarily charged by it in respect of the

 

- 23 -

 

issuance, amendment, cancellation, negotiation or transfer of each Letter of Credit and each
drawing made thereunder. The letter of credit fronting fee is in addition to (and not
included in) the letter of credit participation fee provided for in paragraph (c)
below. Accrued and unpaid fronting fees under the Existing Credit Agreement shall be paid
on the Closing Date or, if later, upon receipt of a bill from the Agent.

(c) Letter of Credit Participation Fee. The Borrower agrees to pay to the
Agent for the pro-rata account of the Lenders (including the Issuer) a letter of credit
participation fee with respect to each Letter of Credit from and including the date of
issuance thereof until the date such Letter of Credit is fully drawn, canceled or expired,
in an amount equal to the Applicable Letter of Credit Participation Fee Rate on the
aggregate amount from time to time available to be drawn on such Letter of Credit,
calculated with respect to actual days elapsed on the basis of a 360-day year and payable
quarterly in arrears on each Payment Date in each year and upon the expiration, cancellation
or utilization in full of such Letter of Credit. During the continuance of a Default, the
Required Lenders may, at their option, by notice to the Borrower, declare that the
Applicable Letter of Credit Participation Fee Rate shall be increased by 2% per annum;
provided, that during the continuance of a Default under Section 7.6 or
7.7, the Applicable Letter of Credit Participation Fee Rate shall be increased by
two percent (2%) without any election or action on the part of the Agent or any Lender.
Accrued and unpaid Letter of Credit Participation Fees under the Existing Credit Agreement
shall be paid on the Closing Date or, if later, upon receipt of a bill from the Agent.

(d) If at any time a Lender is a Defaulting Lender, then, to the extent
permitted by applicable law (and notwithstanding any other provision of this Agreement), (i)
any payment of Reimbursement Obligations with respect to Letters of Credit (including
through sharing of payments pursuant to Section 10.2, but excluding any payment
pursuant to Section 2.3(b) shall, if the Borrower so directs at the time of making
such payment, be applied first to amounts owed to Lenders other than such Defaulting Lender,
as if the amount owed to such Defaulting Lender hereunder in respect of Reimbursement
Obligations were zero, and then to amounts owed to such Defaulting Lender; (ii) such
Defaulting Lender’s pro-rata share of the Letter of Credit Obligations shall be excluded for
purposes of calculating facility fees pursuant to Section 2.9 in respect of each day
on which such Lender is a Defaulting Lender, and such Defaulting Lender shall not be
entitled to receive any facility fees for any such day and (iii) such Defaulting Lender’s
pro-rata share shall be deemed to be zero for purposes of calculating letter of credit fees
pursuant to Section 2.9 in respect of each day on which such Lender is a Defaulting
Lender (and the pro-rata shares of the other Lenders shall be correspondingly increased for
such purposes), and such Defaulting Lender shall not be entitled to receive any letter of
credit fees for any such day. In addition, if any Lender is a Defaulting Lender at the time
any payment is to be made by the Lenders to the Issuer pursuant to Section 2.4(c)
and such Defaulting Lender fails to make its pro-rata share of such payment, then, solely
for purposes of determining the amount of the payment to be made by each Lender to the
Issuer (and without limiting the liability of such Defaulting
Lender for its failure to make such payment), the pro-rata shares of the other Lenders

 

- 24 -

 

shall be correspondingly increased so that, subject to the following proviso, the Issuer
receives the full amount of the payments to which it is entitled from the Lenders;
provided that under no circumstances shall any Lender be obligated to make a payment
to the Issuer pursuant to this sentence that would cause the aggregate principal amount of
such Lender’s pro-rata share (without giving effect to any adjustment pursuant to the
foregoing provisions of this sentence) of all Letter of Credit Obligations to exceed such
Lender’s commitment amount (or, if the Letter of Credit Commitment has terminated, such
Lender’s commitment amount at the time of such termination, adjusted for any assignments by
or to such Lender). Any payment made pursuant to this Section shall be taken into account
for purposes of calculating the Unused Fee and Letter of Credit Participation Fee. The
provisions of this Section 2.9(d) do not limit, but are in addition to, any other
claim or right that the Borrower, the Agent, the Issuer or any other Lender may have against
a Defaulting Lender.

2.10 Extension of Letter of Credit Availability Termination Date. The Borrower may
request an extension of the Letter of Credit Availability Termination Date by submitting a
request for an extension to the Agent (an “Extension Request”) on any Business Day that
is not less than 30 days prior to the then Letter of Credit Availability Termination Date. The
Extension Request must specify the new Letter of Credit Availability Termination Date requested
by the Borrower and the date as of which date (which must be at least 30 days after the
Extension Request is delivered to the Agent) the Lenders (including the Issuer) must respond to
the Extension Request (the “Response Date”). The new Letter of Credit Availability
Termination Date shall not be more than two years after the Letter of Credit Availability
Termination Date in effect at the time the Extension Request is received, including the Letter
of Credit Availability Termination Date as one of the days in the calculation of the days
elapsed. Promptly upon receipt of an Extension Request, the Agent shall notify each Lender of
the contents thereof and shall request the Issuer and each Lender to approve the Extension
Request. Each Lender approving the Extension Request shall deliver its written consent no later
than the Response Date. If the consent of all of the Lenders in their sole discretion is
received by the Agent, the Letter of Credit Availability Termination Date specified in the
Extension Request shall become effective on the existing Letter of Credit Availability
Termination Date and the Agent shall promptly notify the Borrower and each Lender (including the
Issuer) of the new Letter of Credit Availability Termination Date. Otherwise the Letter of
Credit Availability Termination Date shall be unchanged.

2.11 Optional Increase in Letter of Credit Commitment. The Borrower may, from time
to time, by means of a letter delivered to the Agent substantially in the form of Exhibit
D, request that the Letter of Credit Commitment be increased by an aggregate amount (for all
such increases) not exceeding $25,000,000 by (a) increasing the Letter of Credit Participation
Amount of one or more Lenders that have agreed to such increase (in their sole discretion)
and/or (b) adding one or more commercial banks or other Persons as a party hereto (each an
“Additional Lender”) with a Letter of Credit Participation Amount in an amount agreed to
by any such Additional Lender; provided that (i) any increase in the
Letter of Credit Commitment shall be in an aggregate amount of $1,000,000 or a higher
integral multiple of

 

- 25 -

 

$1,000,000, (ii) no Additional Lender shall be added as a party hereto
without the written consent of the Agent and the Issuer (which consents shall not be
unreasonably withheld) or if a Default or an Unmatured Default exists and (iii) the Borrower may
not request an increase in the Letter of Credit Commitment unless the Borrower has delivered to
the Agent (with a copy for each Lender) a certificate stating that the representations and
warranties contained in Article V are correct on and as of the date of such certificate as
though made on and as of such date and that no Default or Unmatured Default exists on such date.
Any increase in the Letter of Credit Commitment pursuant to this Section 2.11 shall be
effective three (3) Business Days after the date on which the Agent has received and accepted
the applicable increase letter in the form of Annex 1 to Exhibit D (in the case
of an increase in the Letter of Credit Participation Amount of an existing Lender) or assumption
letter in the form of Annex 2 to Exhibit D (in the case of the addition of a
commercial bank or other Person as a new Lender). The Agent shall promptly notify the Borrower
and the Lenders of any increase in the Letter of Credit Commitment pursuant to this
Section 2.11 and of the Letter of Credit Participation Amount and pro-rata share of each
Lender after giving effect thereto. To the extent that any increase pursuant to this
Section 2.11 is not expressly authorized pursuant to resolutions or consents delivered
pursuant to Section 4.1(b), the Borrower shall, prior to the effectiveness of such
increase, deliver to the Agent a certificate signed by an authorized officer of the Borrower
certifying and attaching the resolutions or consents that have been adopted to approve or
consent to such increase.

2.12 Collateral Account.

(a) The Borrower shall at all times maintain Cash Collateral Investments in Collateral
Accounts with a Collateral Value of not less than the Required Amount. If at any time the
Required Amount shall exceed (the amount of such excess, the “Collateral Shortfall”)
the Collateral Value for three (3) consecutive Business Days, the Agent shall provide the
Borrower notice, by telephone or in writing, of such Collateral Shortfall and it shall be a
Default unless within three (3) Business Days of the Borrower’s receipt of such notice, no
Collateral Shortfall exists as a result of (i) a change in the Collateral Value due to
market fluctuations and/or (ii) a deposit by the Borrower of additional Cash Collateral
Investments in a Collateral Account.

(b) Cash Collateral Investments held in a Collateral Account shall be invested (i) so
long as no Default has occurred, at the direction of the Borrower, provided that all
such Cash Collateral Investments must be reasonably acceptable to the Agent and otherwise
permitted by this Agreement, and (ii) following the occurrence and continuation of a
Default, at the direction of the Agent. All income from such Cash Collateral Investments
shall be retained in a Collateral Account and added to the Collateral.

(c) So long as no Default has occurred and is continuing, if at any time the
Obligations become due and payable hereunder, the Borrower may direct the application
of all or any part of the Cash Collateral Investments held in a Collateral Account for
the amount which is due and payable, including with respect to any Reimbursement

 

- 26 -

 

Obligations; provided, however, the Agent shall have the right, upon five
(5) days’ prior notice to the Borrower, to apply all or any part of the Cash Collateral
Investments held in a Collateral Account for the amount which is due and payable unless the
Borrower shall object in writing and otherwise pay the amount due and payable within such
five (5) day period. Upon the occurrence and continuation of a Default, the Agent may apply
(without prior notice to the Borrower) all or any part of the Cash Collateral Investments
held in a Collateral Account pursuant to and in accordance with Section 8.4.

(d) So long as no Default or Unmatured Default under Section 7.2 has occurred,
at any time the Collateral Value exceeds (the amount of such excess, the “Collateral
Excess”) the Required Amount, the Borrower can request to receive or otherwise direct
the application of such Collateral Excess and the Agent shall release any Lien it has with
respect to such Collateral Excess; provided, however, upon the occurrence
and continuation of a Default, the Agent shall have sole control over any such Collateral
Excess, including the application of such amount pursuant to and in accordance with
Section 8.4.

ARTICLE III

YIELD PROTECTION; TAXES

3.1 Yield Protection. If, on or after the Closing Date, the adoption of any law or
any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether
or not having the force of law), or any change in the interpretation or administration thereof
by any governmental or quasi-governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by any Lender or applicable
Lending Installation with any request or directive (whether or not having the force of law) of
any such authority, central bank or comparable agency:

(a) subjects any Lender or any applicable Lending Installation to any Taxes, or changes
the basis of taxation of payments (other than with respect to Excluded Taxes) to any Lender
in respect of its interest in the Letters of Credit,

(b) imposes or increases or deems applicable any reserve, assessment, insurance charge,
special deposit or similar requirement against assets of, deposits with or for the account
of, or credit extended by, any Lender or any applicable Lending Installation (other than
reserves and assessments taken into account in determining the interest rate applicable to
Eurodollar Advances), or

(c) imposes any other condition the result of which is to increase the cost to any
Lender or any applicable Lending Installation of making, funding or issuing Letters of
Credit or reduces any amount receivable by any Lender or any applicable Lending Installation
in connection with any Letter of Credit, or requires any Lender or any
applicable Lending Installation to make any payment calculated by reference to the

 

- 27 -

 

amount of Letters of Credit issued or participated in or interest received by it, by an
amount deemed material by such Lender,

and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending
Installation of making or maintaining its Letter of Credit Commitment or its interest in the
Letters of Credit or to reduce the return received by such Lender or applicable Lending
Installation in connection with such Letter of Credit Commitment or interest in Letters of Credit,
then, within fifteen (15) days of demand by such Lender, the Borrower shall pay such Lender such
additional amount or amounts as will compensate such Lender for such increased cost or reduction in
amount received.

3.2 Changes in Capital Adequacy Regulations. If a Lender determines the amount of
capital required or expected to be maintained by such Lender, any Lending Installation of such
Lender or any corporation controlling such Lender is increased as a result of a Change, then,
within fifteen (15) days of demand by such Lender, the Borrower shall pay such Lender the amount
necessary to compensate for any shortfall in the rate of return on the portion of such increased
capital which such Lender determines is attributable to this Agreement, or its commitment to
participate in Letters of Credit hereunder (after taking into account such Lender’s policies as to
capital adequacy). “Change” means (a) any change after the Closing Date in the Risk-Based
Capital Guidelines or (b) any adoption of or change in any other law, governmental or
quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or
not having the force of law) after the Closing Date which affects the amount of capital required or
expected to be maintained by any Lender or any Lending Installation or any corporation controlling
any Lender. “Risk-Based Capital Guidelines” means (i) the risk-based capital guidelines in effect
in the United States on the Closing Date, including transition rules and (ii) the corresponding
capital regulations promulgated by regulatory authorities outside the United States implementing
the November 2005 updated report of the Basel Committee on Banking Regulation and Supervisory
Practices Entitled “International Convergence of Capital Measurements and Capital Standards: A
Revised Framework,” including transition rules, and any amendments to such regulations adopted
prior to the Closing Date.

3.3 Taxes. (a) All payments by the Borrower to or for the account of any Lender or
the Agent hereunder or under any Reimbursement Agreement shall be made free and clear of and
without deduction for any and all Taxes. If the Borrower shall be required by law to deduct any
Taxes from or in respect of any sum payable hereunder to any Lender or the Agent, (i) the sum
payable shall be increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section 3.3) such Lender or the
Agent (as the case may be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay
the full amount deducted to the relevant authority in accordance with applicable law and (iv) the
Borrower shall furnish to the Agent the original copy of a receipt evidencing payment thereof
within thirty (30) days after such payment is made.

(b) In addition, the Borrower hereby agrees to pay any present or future stamp or
documentary taxes and any other excise or property taxes, charges or similar levies

 

- 28 -

 

which
arise from any payment made hereunder or under any other Facility Document or from the
execution or delivery of, or otherwise with respect to, this Agreement or any other Facility
Document (“Other Taxes”).

(c) The Borrower hereby agrees to indemnify the Agent and each Lender for the full
amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes
imposed on amounts payable under this Section 3.3) paid by the Agent or such Lender
and any liability (including penalties, interest and expenses) arising therefrom or with
respect thereto. Payments due under this indemnification shall be made within thirty (30)
days of the date the Agent or such Lender makes demand therefor pursuant to
Section 3.4.

(d) Each Lender that is not incorporated under the laws of the United States of America
or a state thereof (each a “Non-U.S. Lender”) agrees that it will, not less than ten
(10) Business Days after the date of this Agreement, deliver to each of the Borrower and the
Agent such properly completed and executed documentation prescribed by applicable law or
reasonably requested by the Borrower, certifying that such Lender is entitled to receive
payments under this Agreement without deduction or withholding of any United States federal
income taxes. Each Non-U.S. Lender further undertakes to deliver to each of the Borrower
and the Agent (x) renewals or additional copies of such form (or any successor form) on or
before the date that such form expires or becomes obsolete and (y) after the occurrence of
any event requiring a change in the most recent forms so delivered by it, such additional
forms or amendments thereto as may be reasonably requested by the Borrower or the Agent.
All forms or amendments described in the preceding sentence shall certify that such Lender
is entitled to receive payments under this Agreement without deduction or withholding of any
United States federal income taxes, unless an event (including without limitation any change
in treaty, law or regulation) has occurred prior to the date on which any such delivery
would otherwise be required which renders all such forms inapplicable or which would prevent
such Lender from duly completing and delivering any such form or amendment with respect to
it and such Lender advises the Borrower and the Agent that it is not capable of receiving
payments without any deduction or withholding of United States federal income tax.

(e) For any period during which a Non-U.S. Lender has failed to provide the Borrower
with an appropriate form pursuant to paragraph (d) above (unless such failure is due
to a change in treaty, law or regulation, or any change in the interpretation or
administration thereof by any governmental authority, occurring subsequent to the date on
which a form originally was required to be provided), such Non-U.S. Lender shall not be
entitled to indemnification under this Section 3.3 with respect to Taxes imposed by
the United States; provided that, should a Non-U.S. Lender which is otherwise exempt
from or subject to a reduced rate of withholding tax become subject to Taxes because of its
failure to deliver a form required under paragraph (d) above, the Borrower shall
take such
steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S. Lender
to recover such Taxes.

 

- 29 -

 

(f) Any Lender that is entitled to an exemption from or reduction of withholding tax
with respect to payments under this Agreement or any other Facility Document pursuant to the
law of any relevant jurisdiction or any treaty shall deliver to the Borrower (with a copy to
the Agent), at the time or times prescribed by applicable law, such properly completed and
executed documentation prescribed by applicable law as will permit such payments to be made
without withholding or at a reduced rate.

(g) If the U.S. Internal Revenue Service or any other governmental authority of the
United States or any other country or any political subdivision thereof asserts a claim that
the Agent did not properly withhold tax from amounts paid to or for the account of any
Lender (because the appropriate form was not delivered or properly completed, because such
Lender failed to notify the Agent of a change in circumstances which rendered its exemption
from withholding ineffective, or for any other reason), such Lender shall indemnify the
Agent fully for all amounts paid, directly or indirectly, by the Agent as tax, withholding
therefor, or otherwise, including penalties and interest, and including taxes imposed by any
jurisdiction on amounts payable to the Agent under this subsection, together with all costs
and expenses related thereto (including attorneys fees and time charges of attorneys for the
Agent, which attorneys may be employees of the Agent). The obligations of the Lenders under
this Section 3.3(g) shall survive the payment of the Obligations and termination of
this Agreement.

3.4 Lender Statements; Survival of Indemnity. To the extent reasonably possible,
each Lender shall designate an alternate Lending Installation to reduce any liability of the
Borrower to such Lender under Sections 3.1, 3.2 and 3.3 so long as such
designation is not, in the judgment of such Lender, disadvantageous to such Lender. Each Lender
shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as
to the amount due, if any, under Section 3.1, 3.2 or 3.3. Such written
statement shall set forth in reasonable detail the calculations upon which such Lender
determined such amount and shall be final, conclusive and binding on the Borrower in the absence
of manifest error. The obligations of the Borrower under Section 3.1, 3.2 and
3.3 shall survive payment of the Obligations and termination of this Agreement.

ARTICLE V

REPRESENTATIONS AND WARRANTIES

The Borrower represents and warrants to the Lenders that:

5.1 Existence and Standing. Each of the Borrower and its Subsidiaries is duly and
properly formed, validly existing and in good standing under the laws of its jurisdiction of
incorporation or organization and, except as could not reasonably be expected to have a Material
Adverse Effect, has all requisite authority to conduct its business in each jurisdiction in
which its business is conducted.

5.2 Authorization and Validity. The Borrower has the corporate power and authority
and legal right to execute and deliver the Facility Documents and to perform its obligations
thereunder. The execution and delivery by the Borrower of the Facility Documents and the
performance of its obligations thereunder have been duly authorized by proper corporate
proceedings, and the Facility Documents to which the Borrower is a party constitute legal, valid
and binding obligations of the Borrower enforceable against the Borrower in accordance with
their terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws
affecting the enforcement of creditors’ rights generally.

5.3 No Conflict; Government Consent. Neither the execution and delivery by the
Borrower of the Facility Documents, nor the consummation of the transactions therein
contemplated, nor compliance with the provisions thereof will violate (a) any law, rule,
regulation, order, writ, judgment, injunction, decree or award binding on the Borrower or any of
its Subsidiaries or (b) the Borrower’s or any Subsidiary’s articles or certificate of
incorporation, partnership agreement, certificate of partnership, articles or certificate of
organization, by-laws, or operating or other management agreement, as the case may be, or (c)
the provisions of any indenture, instrument or agreement to which the Borrower or any of
its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or
conflict with or constitute a default thereunder, or result in, or require, the creation or
imposition of

 

- 32 -

 

any Lien in, of or on the Property of the Borrower or a Subsidiary pursuant to the
terms of any such indenture, instrument or agreement. No order, consent, adjudication,
approval, license, authorization, or validation of, or filing, recording or registration with,
or exemption by, or other action in respect of any governmental or public body or authority, or
any subdivision thereof, which has not been obtained by the Borrower or any of its Subsidiaries,
is required to be obtained by the Borrower or any of its Subsidiaries in connection with the
execution and delivery of the Facility Documents, the extensions of credit under this Agreement,
the payment and performance by the Borrower of the Obligations or the legality, validity,
binding effect or enforceability of any of the Facility Documents, except that approval of the
New York Insurance Department and/or one or more other state insurance departments would be
required in order for the Lenders to acquire control of Navigators and NSIC. Neither the
Borrower nor any Subsidiary is in default under or in violation of any foreign, federal, state
or local law, rule, regulation, order, writ, judgment, injunction, decree or award binding upon
or applicable to the Borrower or such Subsidiary, in each case the consequences of which default
or violation could reasonably be expected to have a Material Adverse Effect.

5.4 Financial Statements. (a) The consolidated balance sheets of the Borrower and
the Consolidated Subsidiaries as of December 31, 2009, the related consolidated statements of
income, consolidated statements of stockholders’ equity, and consolidated statements of cash
flows of the Borrower and such Consolidated Subsidiaries for the Fiscal Year then ended, and the
accompanying footnotes, together, with the opinion thereon, of KPMG LLP, independent certified
public accountants, copies of which have been furnished to the Lenders, fairly present the
financial condition of the Borrower and the Consolidated Subsidiaries as at such dates and the
results of the operations of the Borrower and Consolidated Subsidiaries for the periods covered
by such statements, all in accordance with Agreement Accounting Principles consistently applied.

(b) There are no liabilities of the Borrower or any of the Consolidated Subsidiaries,
fixed or contingent, which are material but are not reflected in the most recent financial
statements referred to above or in the notes thereto, other than liabilities arising in the
ordinary course of business since December 31, 2009.

5.5 Statutory Financial Statements. The Annual Statement of each of the Insurance
Subsidiaries (including, without limitation, the provisions made therein for investments and the
valuation thereof, reserves, policy and contract claims and statutory liabilities) as filed with
the appropriate Governmental Authority of its state of domicile (the “Department”) and
delivered to each Lender prior to the execution and delivery of this Agreement, as of and for
the 2009 Fiscal Year (the “Statutory Financial Statements”), have been prepared in
accordance with SAP applied on a consistent basis (except as noted therein). Each such
Statutory Financial Statement was in material compliance with applicable law when filed.

5.6 Material Adverse Change. Since December 31, 2009 there has been no change in
the business, Property, condition (financial or otherwise) or results of operations of

 

- 33 -

 

the
Borrower and its Subsidiaries which could reasonably be expected to have a Material Adverse
Effect.

5.7 Taxes. The Borrower and its Subsidiaries have filed all United States federal
tax returns and all other tax returns which are required to be filed and have paid all taxes due
pursuant to said returns or pursuant to any assessment received by the Borrower or any of its
Subsidiaries, except such taxes, if any, as are being contested in good faith and as to which
adequate reserves have been provided in accordance with Agreement Accounting Principles and as
to which no Lien exists. No tax liens have been filed and no claims are being asserted with
respect to any such taxes. The charges, accruals and reserves on the books of the Borrower and
its Subsidiaries in respect of any taxes or other governmental charges are adequate.

5.8 Litigation and Contingent Obligations. There is no litigation, arbitration,
governmental investigation, proceeding or inquiry pending or, to the knowledge of any of their
officers, threatened against or affecting the Borrower or any of its Subsidiaries which could
reasonably be expected to have a Material Adverse Effect or which seeks to prevent, enjoin or
delay the issuance of any Letters of Credit. Other than any liability incident to any
litigation, arbitration or proceeding which could not reasonably be expected to have a Material
Adverse Effect, the Borrower has no material contingent obligations not provided for or
disclosed in the financial statements referred to in Section 5.4.

5.9 Subsidiaries. Schedule 5.9 contains an accurate list of all
Subsidiaries of the Borrower as of the date of this Agreement, setting forth their respective
jurisdictions of organization and the percentage of their respective capital stock or other
ownership interests owned by the Borrower or other Subsidiaries and indicating which
Subsidiaries are Significant Subsidiaries and which Subsidiaries are Insurance Subsidiaries.
All of the issued and outstanding shares of capital stock or other ownership interests of such
Subsidiaries have been (to the extent such concepts are relevant with respect to such ownership
interests) duly authorized and issued and are fully paid and non-assessable.

5.10 ERISA. The Unfunded Liabilities of all Single Employer Plans is $0 except
that funding of any money purchase pension plan may be delayed each Fiscal Year until the end of
the first Fiscal Quarter of the following year. Neither the Borrower nor any other member of
the Controlled Group has incurred, or is reasonably expected to incur, any withdrawal liability
to any Multiemployer Plan. Each Plan complies in all material respects with all applicable
requirements of law and regulations, no Reportable Event has occurred with respect to any Plan,
neither the Borrower nor any other member of the Controlled Group has withdrawn from any Plan or
initiated steps to do so, and no steps have been taken to reorganize or terminate any Plan.

5.11 Defaults. No Default or Unmatured Default has occurred and is continuing.

5.12 Accuracy of Information. No information, exhibit or report furnished by the
Borrower or any of its Subsidiaries to the Agent or to any Lender in connection with the

 

- 34 -

 

negotiation of, or compliance with, the Facility Documents contained any material misstatement
of fact or omitted to state a material fact or any fact necessary to make the statements
contained therein not misleading.

5.13 Regulation U. Margin stock (as defined in Regulation U) constitutes less than
25% of the value of those assets of the Borrower and its Subsidiaries which are subject to any
limitation on sale, pledge, or other restriction hereunder. Neither the issuance of any Letters
of Credit hereunder nor the use of the proceeds thereof, will violate or be inconsistent with
the provisions of Regulation T, Regulation U or Regulation X.

5.14 Material Agreements. Neither the Borrower nor any Subsidiary is a party to
any agreement or instrument or subject to any charter or other corporate restriction which could
reasonably be expected to have a Material Adverse Effect. Neither the Borrower nor any
Subsidiary is in default in the performance, observance or fulfillment of any of the
obligations, covenants or conditions contained in (a) any agreement to which it is a party which
default could reasonably be expected to have a Material Adverse Effect or (b) any agreement or
instrument evidencing or governing Indebtedness.

5.15 Compliance With Laws. The Borrower and its Subsidiaries have complied with
all applicable statutes, rules, regulations, orders and restrictions of any domestic or foreign
government or any instrumentality or agency thereof having jurisdiction over the conduct of
their respective businesses or the ownership of their respective Property, except where the
failure to comply could not reasonably be expected to have a Material Adverse Effect.

5.16 Ownership of Properties. The Borrower and each of its Subsidiaries has good
title, free of all Liens other than those permitted by Section 6.16, to all of the
Property and assets reflected in the Borrower’s most recent consolidated financial statements
filed with the Securities and Exchange Commission as owned by the Borrower and its Subsidiaries.

5.17 Plan Assets; Prohibited Transactions. The Borrower is not an entity deemed to
hold “plan assets” within the meaning of 29 C.F.R. § 2510.3-101 of an employee benefit plan (as
defined in Section 3(3) of ERISA) which is subject to Title I of ERISA or any plan (within the
meaning of Section 4975 of the Code), and neither the execution of this Agreement nor the
issuance of Letters of Credit hereunder gives rise to a prohibited transaction within the
meaning of Section 406 of ERISA or Section 4975 of the Code.

5.18 Environmental Matters. In the ordinary course of its business, the officers
of the Borrower consider the effect of Environmental Laws on the business of the Borrower and
its Subsidiaries, in the course of which they identify and evaluate potential risks and
liabilities accruing to the Borrower due to Environmental Laws. On the basis of this
consideration, the Borrower has concluded that Environmental Laws cannot reasonably
be expected to have a Material Adverse Effect. Neither the Borrower nor any Subsidiary has
received any notice to the effect that its operations are not in material compliance with any of
the requirements of applicable Environmental Laws or are the subject of any federal or state

 

- 35 -

 

investigation evaluating whether any remedial action is needed to respond to a release of any
toxic or hazardous waste or substance into the environment, which non-compliance or remedial
action could reasonably be expected to have a Material Adverse Effect.

5.19 Investment Company Act. Neither the Borrower nor any Subsidiary is an
“investment company” or a company “controlled” by an “investment company”, within the meaning of
the Investment Company Act of 1940, as amended.

5.20 Solvency. Immediately after the consummation of the transactions to occur on
the date hereof and immediately following each issuance of a Letter of Credit (including the
Existing Letters of Credit) hereunder on the date hereof and after giving effect to the
application of the proceeds of such Letters of Credit, (a) the fair value of the assets of the
Borrower and its Subsidiaries on a consolidated basis, at a fair valuation, will exceed the
debts and liabilities, subordinated, contingent or otherwise, of the Borrower and its
Subsidiaries on a consolidated basis, (b) the present fair saleable value of the Property of the
Borrower and its Subsidiaries on a consolidated basis will be greater than the amount that will
be required to pay the probable liability of the Borrower and its Subsidiaries on a consolidated
basis on their debts and other liabilities, subordinated, contingent or otherwise, as such debts
and other liabilities become absolute and matured, (c) the Borrower and its Subsidiaries on a
consolidated basis will be able to pay their debts and liabilities, subordinated, contingent or
otherwise, as such debts and liabilities become absolute and matured and (d) the Borrower and
its Subsidiaries on a consolidated basis will not have unreasonably small capital with which to
conduct the businesses in which they are engaged as such businesses are now conducted and are
proposed to be conducted after the date hereof.

5.21 Insurance Licenses. To the extent required by applicable law, each Insurance
Subsidiary holds a License and is authorized to transact insurance business in (i) the line or
lines of insurance and (ii) the state, states or jurisdictions it is engaged in, except to the
extent that the failure to have such a License or authority could not reasonably be expected to
have a Material Adverse Effect. No such License, the loss of which could reasonably be expected
to have a Material Adverse Effect, is the subject of a proceeding for suspension, limitation or
revocation. To the Borrower’s knowledge, there is not a sustainable basis for such suspension,
limitation or revocation, and no such suspension, limitation or revocation has been threatened
by any Governmental Authority. The Insurance Subsidiaries do not transact any business,
directly or indirectly, requiring any license, permit, governmental approval, consent or other
authorization other than those currently obtained, except to the extent of which could not
reasonably be expected to have a Material Adverse Effect.

5.22 Partnerships. Except as disclosed in Schedule 5.22, neither the
Borrower nor any of its Subsidiaries is a partner of any partnership.

5.23 Lines of Business. Schedule 5.23 sets forth a complete statement of
each material line of business conducted as of the date hereof by the Borrower and each of its
Subsidiaries (the “Existing Lines of Business”).

 

- 36 -

 

5.24 Reinsurance Practices. The business of each Insurance Subsidiary is being
conducted in all material respects in accordance with the Reinsurance Guidelines.

5.25 Security. The Pledge Agreement is effective to create and give the Agent, for
the benefit of the Secured Parties, as security for the repayment of the obligations secured
thereby, a legal, valid, perfected and enforceable first priority Lien upon and security
interest in the capital stock pledged thereby.

5.26 Disclosure. None of the (a) information, exhibits or reports furnished or to
be furnished by the Borrower or any Subsidiary to the Agent or to any Lender in connection with
the negotiation of the Facility Documents or (b) representations or warranties of the Borrower
or any Subsidiary contained in this Agreement, the other Facility Documents or any other
document, certificate or written statement furnished to the Agent or the Lenders by or on behalf

ARTICLE VIII

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

8.1 Acceleration. If any Default described in Section 7.6 or 7.7
occurs with respect to the Borrower, the obligations of the Issuer and the Lenders to issue
Letters of Credit hereunder shall automatically terminate and the Obligations shall immediately
become due and payable without any election or action on the part of the Agent or any Lender.
If any other Default occurs, the Required Lenders (or the Agent with the consent of the Required
Lenders) may terminate or suspend the obligations of the Issuer and the Lenders to issue Letters
of Credit hereunder, or declare the Obligations to be due and payable, or both, whereupon the
Obligations shall become immediately due and payable, without presentment, demand, protest or
notice of any kind, all of which the Borrower hereby expressly waives. In addition to the
foregoing, following the occurrence and during the continuance of a Default, so long as any
Letter of Credit has not been fully drawn and has not been canceled or expired by its terms,
upon demand by the Agent (which demand shall be made upon the request of the Required Lenders),
the Borrower shall deposit, in a Collateral Account, Cash Collateral
Investments with a Collateral Value equal to the product of one hundred and three percent
(103%) of the aggregate undrawn face amount of all outstanding Letters of Credit and all fees
and other amounts due or which may become due with respect thereto.

If, within thirty (30) days after acceleration of the maturity of the Obligations or
termination of the obligations of the Lenders to issue Letters of Credit hereunder as a result
of any Default (other than any Default as described in Section 7.6 or 7.7 with
respect to the Borrower) and before any judgment or decree for the payment of the Obligations
due shall

 

- 50 -

 

have been obtained or entered, the Required Lenders (in their sole discretion) may
direct the Agent to rescind and annul such acceleration and/or termination.

8.2 Amendments. Subject to the provisions of this Article VIII, the
Required Lenders (or the Agent with the consent of the Required Lenders) and the Borrower may
enter into agreements supplemental hereto for the purpose of adding or modifying any provisions
to the Facility Documents or changing in any manner the rights of the Lenders or the Borrower
hereunder or waiving any Default hereunder; provided, however, that no such
supplemental agreement shall, without the consent of each Lender:

(a) Extend the final maturity of any Obligations or forgive all or any portion of the
Reimbursement Obligations, or reduce the rate or extend the time of payment of interest or
fees (including without limitation letter of credit fees) hereunder;

(b) Reduce the percentage specified in the definition of Required Lenders;

(c) Reduce the amount of or extend the date for payment of Reimbursement Obligations or
commitment and facility reductions required under Section 2.4 or 2.10, or
increase the amount of the Letter of Credit Participation Amount of any Lender hereunder;

(d) Extend the Letter of Credit Availability Termination Date; permit any Letter of
Credit to have an expiry date beyond four years after notice, in the case of Lloyd’s Letters
of Credit, or one year after its effective date in the case of other Letters of Credit;
except as permitted in Section 2.5, permit the amendment or extension of any Letter
of Credit; or, except as otherwise set forth in Section 2.1(b), permit the renewal
of any Letter of Credit;

(e) Permit any amendment of Sections 2.4(d) or 8.4;

(f) Release any guarantor of any Obligations or, except as provided in the Pledge
Agreement, release any of the collateral for the Obligations or decrease the amount of
collateral required under Sections 2.1(d), 2.1(f), 2.8,
2.12(a) or 8.1;

(g) Permit any assignment by the Borrower of its Obligations or its rights hereunder;
or

(h) Permit any amendment of the Reinsurance Guidelines;

provided, further, that no such supplemental agreement shall, without the
consent of each Lender, amend this Section 8.2. No amendment of any provision of this
Agreement relating to the Agent shall be effective without the written consent of the Agent.
The Agent may waive payment of the fee required under Section 12.3(b) without obtaining
the consent of any other party to this Agreement. Notwithstanding anything to the contrary
herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver
or

 

- 51 -

 

consent hereunder, except that the commitment of such Lender may not be increased or extended
without the consent of such Lender.

8.3 Preservation of Rights. No delay or omission of the Lenders or the Agent to
exercise any right under the Facility Documents shall impair such right or be construed to be a
waiver of any Default or an acquiescence therein, and the issuance of a Letter of Credit
notwithstanding the existence of a Default or the inability of the Borrower to satisfy the
conditions precedent to such Letter of Credit shall not constitute any waiver or acquiescence.
Any single or partial exercise of any such right shall not preclude other or further exercise
thereof or the exercise of any other right, and no waiver, amendment or other variation of the
terms, conditions or provisions of the Facility Documents whatsoever shall be valid unless in
writing signed by the Lenders required pursuant to Section 8.2, and then only to the
extent in such writing specifically set forth. All remedies contained in the Facility Documents
or by law afforded shall be cumulative and all shall be available to the Agent and the Lenders
until the Obligations have been paid in full.

8.4 Application of Funds. After the occurrence of a Default, any amounts received
on account of the Obligations (including proceeds of Collateral) shall be applied by the Agent
in the following order:

First, to payment of that portion of the Obligations constituting fees, indemnities,
expenses and other amounts (including fees, charges and disbursements of counsel to the Agent and
amounts payable under Article III) payable to the Agent in its capacity as such;

Second, to payment of that portion of the Obligations constituting fees, indemnities
and other amounts (other than Reimbursement Obligations, interest and Letter of Credit fees)
payable to the Lenders and the Issuer (including fees, charges and disbursements of counsel to the
respective Lenders and the Issuer (including, without duplication, fees and time charges for
attorneys who may be employees of any Lender or the Issuer) and amounts payable under Article
III), ratably among them in proportion to the respective amounts described in this clause
Second payable to them;

Third, to payment of that portion of the Obligations constituting accrued and unpaid
Letter of Credit fees and interest on the Reimbursement Obligations and other Obligations, ratably
among the Lenders and the Issuer in proportion to the respective amounts described in this clause
Third payable to them;

Fourth, to payment of that portion of the Obligations constituting unpaid
Reimbursement Obligations, ratably among the Lenders and the Issuer in proportion to the respective
amounts described in this clause Fourth held by them;

Fifth, to the Agent for the account of the Issuer to be held as Collateral for that
portion of Letter of Credit Obligations comprised of the aggregate undrawn amount of Letters of
Credit; and

Last, the balance, if any, after all of the Obligations have been indefeasibly paid in
full and the Letter of Credit Commitment has been terminated, to the Borrower or as otherwise
required by Law.

 

- 52 -

 

Amounts held as Collateral for the aggregate undrawn amount of Letters of Credit pursuant to
clause Fifth above shall be applied to satisfy drawings under such Letters of Credit as
they occur. If any Collateral remains after all Letters of Credit have either been fully drawn or
expired, such remaining amount shall be applied to the other Obligations, if any, in the order set
forth above.

the Lenders hereunder are several and not joint and no Lender shall be the partner or agent of
any other (except to the extent to which the Agent is authorized to act as such). The failure

9.9 Severability of Provisions. Any provision in any Facility Document that is
held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that
jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining
provisions in that jurisdiction or the operation, enforceability, or validity of that provision
in any other jurisdiction, and to this end the provisions of all Facility Documents are declared
to be severable.

9.10 Nonliability of Lenders. The relationship between the Borrower on the one
hand and the Lenders and the Agent on the other hand shall be solely that of borrower and
lender. Neither the Agent, the Arranger nor any Lender shall have any fiduciary
responsibilities to the Borrower. Neither the Agent, the Arranger nor any Lender undertakes any

any phase of the Borrower’s business or operations. The Borrower agrees that neither the Agent,
the Arranger nor any Lender shall have liability to the Borrower (whether sounding in tort,
contract or otherwise) for losses suffered by the Borrower in

 

- 54 -

 

connection with, arising out of,
or in any way related to, the transactions contemplated and the relationship established by the
Facility Documents, or any act, omission or event occurring in connection therewith, unless it
is determined in a final non-appealable judgment by a court of competent jurisdiction that such
losses resulted from the gross negligence or willful misconduct of the party from which recovery
is sought. Neither the Agent, the Arranger nor any Lender shall have any liability with respect
to, and the Borrower hereby waives, releases and agrees not to sue for, any special, indirect,
punitive or consequential damages suffered by the Borrower in connection with, arising out of,
or in any way related to the Facility Documents or the transactions contemplated thereby.

ARTICLE X

THE ADMINISTRATIVE AGENT

10.1 Appointment; Nature of Relationship. JPMorgan Chase Bank is hereby appointed
by each of the Lenders as Administrative Agent (herein referred to as the “Agent”)
hereunder and under each other Facility Document, and each of the Lenders irrevocably authorizes
the Agent to act as the Administrative Agent of such Lender with the rights and duties expressly
set forth herein and in the other Facility Documents. The Agent agrees to act as such
Administrative Agent upon the express conditions contained in this Article X.
Notwithstanding the use of the defined term “Agent,” it is expressly understood and agreed that
the Agent shall not have any fiduciary responsibilities to any Lender by reason of this
Agreement or any other Facility Document and that the Agent is merely acting as the
Administrative Agent of the Lenders with only those duties as are expressly set forth in this
Agreement and the other Facility Documents. In its capacity as the Lenders’ Administrative
Agent, the Agent (a) does not hereby assume any fiduciary duties to any of the Lenders, (b) is a
“representative” of the Lenders within the meaning of Section 9-105 of the Uniform Commercial
Code and (c) is acting as an independent contractor, the rights and duties of which are limited
to those expressly set forth in this Agreement and the other Facility Documents. Each of the
Lenders hereby agrees to assert no claim against the Agent on any agency theory or any other
theory of liability for breach of fiduciary duty, all of which claims each Lender hereby waives.

10.2 Powers. The Agent shall have and may exercise such powers under the Facility
Documents as are specifically delegated to the Agent by the terms of each thereof, together with
such powers as are reasonably incidental thereto. The Agent shall have no implied duties to the
Lenders, or any obligation to the Lenders to take any action thereunder except any action
specifically provided by the Facility Documents to be taken by the Agent.

10.3 General Immunity. Neither the Agent nor any of its directors, officers,
agents or employees shall be liable to the Borrower, the Lenders or any Lender for any action
taken or omitted to be taken by it or them hereunder or under any other Facility Document or in
connection herewith or therewith except to the extent such action or inaction is determined in a
final non-appealable judgment by a court of competent jurisdiction to have arisen from the gross
negligence or willful misconduct of such Person.

10.4 No Responsibility for Recitals, etc. Neither the Agent nor any of its
directors, officers, agents or employees shall be responsible for or have any duty to ascertain,
inquire into, or verify: (a) any statement, warranty or representation made in connection with
any Facility Document or any borrowing hereunder, (b) the performance or observance of any of
the covenants or agreements of any obligor under any Facility Document, including, without
limitation, any agreement by an obligor to furnish information directly to each Lender, (c) the

 

- 56 -

 

satisfaction of any condition specified in Article IV, except receipt of items required
to be delivered solely to the Agent, (d) the existence or possible existence of any Default or
Unmatured Default, (e) the validity, enforceability, effectiveness, sufficiency or genuineness
of any Facility Document or any other instrument or writing furnished in connection therewith,
(f) the value, sufficiency, creation, perfection or priority of any Lien in any collateral
security or (g) the financial condition of the Borrower or any guarantor of any of the
Obligations or of any of the Borrower’s or any such guarantor’s respective Subsidiaries. The
Agent shall have no duty to disclose to the Lenders information that is not required to be
furnished by the Borrower to the Agent at such time, but is voluntarily furnished by the
Borrower to the Agent (either in its capacity as Agent or in its individual capacity).

10.5 Action on Instructions of Lenders. The Agent shall in all cases be fully
protected in acting, or in refraining from acting, hereunder and under any other Facility
Document in accordance with written instructions signed by the Required Lenders, and such
instructions and any action taken or failure to act pursuant thereto shall be binding on all of
the Lenders. The Lenders hereby acknowledge that the Agent shall be under no duty to take any
discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or
any other Facility Document unless it shall be requested in writing to do so by the Required
Lenders. The Agent shall be fully justified in failing or refusing to take any action hereunder
and under any other Facility Document unless it shall first be indemnified to its satisfaction
by the Lenders pro-rata against any and all liability, cost and expense that it may incur by
reason of taking or continuing to take any such action.

10.6 Employment of Agent and Counsel. The Agent may execute any of its duties as
Agent hereunder and under any other Facility Document by or through employees, agents, and
attorneys-in-fact and shall not be answerable to the Lenders, except as to money or securities
received by it or its authorized agents, for the default or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care. The Agent shall be entitled to advice of
counsel concerning the contractual arrangement between the Agent and the Lenders and all matters
pertaining to the Agent’s duties hereunder and under any other Facility Document.

10.7 Reliance on Documents; Counsel. The Agent shall be entitled to rely upon any
notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed
by it to be genuine and correct and to have been signed or sent by the proper person or persons,
and, in respect to legal matters, upon the opinion of counsel selected by the Agent, which
counsel may be employees of the Agent.

10.8 Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and
indemnify the Agent ratably in proportion to their Letter of Credit Participation Amount (or, if
the Letter of Credit Commitments has been terminated, in proportion to its Letter of Credit
Participation Amount immediately prior to such termination) (a) for any amounts not reimbursed
by the Borrower for which the Agent is entitled to reimbursement by the Borrower under the
Facility Documents, (b) for any other expenses incurred by the Agent on behalf of the Lenders,
in connection with the preparation,

 

- 57 -

 

execution, delivery, administration and enforcement of the
Facility Documents (including, without limitation, for any expenses incurred by the Agent in
connection with any dispute between the Agent and any Lender or between two or more of the
Lenders) and (c) for any liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may
be imposed on, incurred by or asserted against the Agent in any way relating to or arising out
of the Facility Documents or any other document delivered in connection therewith or the
transactions contemplated thereby (including, without limitation, for any such amounts incurred
by or asserted against the Agent in connection with any dispute between the Agent and any Lender
or between two or more of the Lenders), or the enforcement of any of the terms of the Facility
Documents or of any such other documents; provided that (i) no Lender shall be liable for any of
the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by
a court of competent jurisdiction to have resulted from the gross negligence or willful
misconduct of the Agent and (ii) any indemnification required pursuant to Section 3.5(g)
shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant
Lender in accordance with the provisions thereof. The obligations of the Lenders under this
Section 10.8 shall survive payment of the Obligations and termination of this Agreement.

10.9 Notice of Default. The Agent shall not be deemed to have knowledge or notice
of the occurrence of any Default or Unmatured Default hereunder unless the Agent has received
written notice from a Lender or the Borrower referring to this Agreement describing such Default
or Unmatured Default and stating that such notice is a “notice of default”. In the event that
the Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders.

10.10 Rights as a Lender. In the event the Agent is a Lender, the Agent shall have
the same rights and powers hereunder and under any other Facility Document with respect to its
Letter of Credit Participation Amount, and any Letters of Credit in which it has an interest as
any Lender and may exercise the same as though it were not the Agent, and the term “Lender” or
“Lenders” shall, at any time when the Agent is a Lender, unless the context otherwise indicates,
include the Agent in its individual capacity. The Agent and its Affiliates may accept deposits
from, lend money to, and generally engage in any kind of trust, debt, equity or other
transaction, in addition to those contemplated by this Agreement or any other Facility Document,
with the Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary is not
restricted hereby from engaging with any other Person. The Agent, in its individual capacity,
is not obligated to remain a Lender.

10.11 Rights with Respect to Designated Lenders. If any Lender is a Designated
Lender, then the Issuer may, by notice to such Designated Lender and the Agent, require such
Designated Lender to (a) deliver to the Agent, for the account of the Issuer, cash collateral in
an amount equal to the product of one hundred and three percent (103%) of the remainder of (i)
such Designated Lender’s pro-rata share of the Letter of Credit Commitment minus (ii) the
principal amount of such Designated Lender’s pro-rata share of the Letter of Credit Obligations
then outstanding (the “Reserve Amount”) or (b) and solely with respect to a Designated
Lender that is not a Defaulting Lender, make other arrangements reasonably

 

- 58 -

 

satisfactory to the
Issuer to assure that such Designated Lender will reimburse the Issuer for its pro-rata share of
any payment made by the Issuer under any Letter of Credit. Any such cash collateral (i) shall
be held by the Agent pursuant to arrangements reasonably satisfactory to such Designated Lender,
the Issuer and the Agent and (ii) if at any time such Designated Lender becomes obligated to pay
any amount to the Issuer pursuant to Section 2.4, shall be applied (to the extent
required) by the Agent to pay such amount. Upon the expiration, termination or reduction in
amount of any applicable Letter of Credit, the Agent shall release (subject to Section
2.9(d) in the case of a Defaulting Lender) to such Designated Lender (or such other Person
as may be entitled thereto) any cash collateral held by the Agent in excess of the Reserve
Amount. If any Designated Lender fails to provide cash collateral or make other arrangements as
required by the first sentence of this Section 10.11, then the Agent shall retain as
cash collateral all amounts otherwise payable to such Designated Lender under this Agreement
until the Agent has retained an amount equal to the Reserve Amount.

10.12 Lender Credit Decision. Each Lender acknowledges that it has, independently
and without reliance upon the Agent, the Arranger or any other Lender and based on the financial
statements prepared by the Borrower and such other documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this Agreement and the
other Facility Documents. Each Lender also acknowledges that it will, independently and without
reliance upon the Agent, the Arranger or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement and the other Facility Documents.

10.13 Successor Agent. The Agent may resign at any time by giving written notice
thereof to the Lenders and the Borrower, such resignation to be effective upon the appointment
of a successor Agent or, if no successor Agent has been appointed, forty-five days after the
retiring Agent gives notice of its intention to resign. The Agent may be removed at any time
with or without cause by written notice received by the Agent from the Required Lenders, such
removal to be effective on the date specified by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint, on behalf of the
Borrower and the Lenders, a successor Agent. If no successor Agent shall have been so appointed
by the Required Lenders within thirty days after the resigning Agent’s giving notice of its
intention to resign, then the resigning Agent may appoint, on behalf of the Borrower and the
Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time
without the consent of the Borrower or any Lender, appoint any of its Affiliates which is a
commercial bank as a successor Agent
hereunder. If the Agent has resigned or been removed and no successor Agent has been
appointed, the Lenders may perform all the duties of the Agent hereunder and the Borrower shall
make all payments in respect of the Obligations to the applicable Lender and for all other
purposes shall deal directly with the Lenders. No successor Agent shall be deemed to be
appointed hereunder until such successor Agent has accepted the appointment. Any such successor
Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor
Agent shall thereupon succeed to and become vested with all the

 

- 59 -

 

rights, powers, privileges and
duties of the resigning or removed Agent. Upon the effectiveness of the resignation or removal
of the Agent, the resigning or removed Agent shall be discharged from its duties and obligations
hereunder and under the Facility Documents. After the effectiveness of the resignation or
removal of an Agent, the provisions of this Article X shall continue in effect for the
benefit of such Agent in respect of any actions taken or omitted to be taken by it while it was
acting as the Agent hereunder and under the other Facility Documents. In the event that there
is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an
Affiliate pursuant to this Section 10.13, then the term “Prime Rate” as used in this
Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

10.14 Agents’ Fees. The Borrower agrees to pay to the Agent, for its own account,
the fees agreed to by the Borrower and the Agent pursuant to the Fee Letter.

10.15 Delegation to Affiliates. The Borrower and the Lenders agree that the Agent
may delegate any of its duties under this Agreement to any of its Affiliates. Any such
Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs duties
in connection with this Agreement shall be entitled to the same benefits of the indemnification,
waiver and other protective provisions to which the Agent is entitled under Articles IX
and X.

10.16 Joint Lead Arranger; Syndication Agent; Documentation Agent. The Joint Lead
Arrangers (other than the Arranger), the Syndication Agent and the Documentation Agent shall
have no right, power, obligation, liability, responsibility or duty under this Agreement other
than those applicable to all Lenders as such. Without limiting the foregoing, the Joint Lead
Arrangers (other than the Arranger), the Syndication Agent and the Documentation Agent shall not
have or be deemed to have a fiduciary relationship with any Lender. Each Lender hereby makes
the same acknowledgements with respect to the Joint Lead Arrangers (other than the Arranger),
the Syndication Agent and the Documentation Agent as it makes to the Agent in
Section 10.10.

ARTICLE XI

SETOFF; RATABLE PAYMENTS

11.1 Setoff. In addition to, and without limitation of, any rights of the Lenders
under applicable law, if the Borrower becomes insolvent, however evidenced, or any
Default occurs, any and all deposits (including all account balances, whether provisional
or final and whether or not collected or available) and any other Indebtedness at any time held
or owing by any Lender to or for the credit or account of the Borrower may be offset and applied
toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or
any part hereof, shall then be due.

11.2 Ratable Payments. If any Lender, whether by setoff or otherwise, has payment
made to it upon its Reimbursement Obligations (other than payments received

 

- 60 -

 

pursuant to
Section 3.1, 3.2 or 3.3) in a greater proportion than that received by
any other Lender, such Lender agrees, promptly upon demand, to purchase a participation
interests in Letters of Credit, as the case may be, held by the other Lenders so that after such
purchase each Lender will hold its ratable proportion of such participation interests in Letters
of Credit. If any Lender, whether in connection with setoff or amounts which might be subject
to setoff or otherwise, receives collateral or other protection for its Obligations or such
amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such
action necessary such that all Lenders share in the benefits of such collateral ratably in
proportion to their Letter of Credit Participation Amounts. In case any such payment is
disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

12.1 Successors and Assigns. The terms and provisions of the Facility Documents
shall be binding upon and inure to the benefit of the Borrower and the Lenders and their
respective successors and assigns, except that (a) the Borrower shall not have the right to
assign its rights or obligations under the Facility Documents and (b) any assignment by any
Lender must be made in compliance with Section 12.3. Notwithstanding clause (b)
of the foregoing sentence, any Lender may at any time, without the consent of the Borrower or
the Agent, assign all or any portion of its rights under this Agreement to a Federal Reserve
Bank; provided, however, that no such assignment to a Federal Reserve Bank shall
release the transferor Lender from its obligations hereunder. The Agent may treat the Person
which participated in any Letter of Credit as the owner thereof for all purposes hereof unless
and until such Person complies with Section 12.3 in the case of an assignment thereof
or, in the case of any other transfer, a written notice of the transfer is filed with the Agent.
Any assignee or transferee of the rights to any Letter of Credit agrees by acceptance of such
transfer or assignment to be bound by all the terms and provisions of the Facility Documents.
Any request, authority or consent of any Person, who at the time of making such request or
giving such authority or consent is the owner of the rights to any Letter of Credit, shall be
conclusive and binding on any subsequent holder, transferee or assignee of the rights to such
Letter of Credit, as the case may be.

12.2 Participations.

(a) Permitted Participants; Effect. Any Lender may, in the ordinary course of
its business and in accordance with applicable law, at any time sell to one or more banks or
other entities (“Participants”) participating interests in any Letter of Credit
Participation Amount of such Lender, any interest of such Lender in any Letters of Credit or
any other interest of such Lender under the Facility Documents. In the event of any such
sale by a Lender of participating interests to a Participant, such Lender’s obligations
under the Facility Documents shall remain unchanged, such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations, such Lender
shall remain the owner of its interest in any Letters of Credit issued to it in

 

- 61 -

 

evidence
thereof for all purposes under the Facility Documents, all amounts payable by the Borrower
under this Agreement shall be determined as if such Lender had not sold such participating
interests, and the Borrower and the Agent shall continue to deal solely and directly with
such Lender in connection with such Lender’s rights and obligations under the Facility
Documents.

(b) Voting Rights. Each Lender shall retain the sole right to approve, without
the consent of any Participant, any amendment, modification or waiver of any provision of
the Facility Documents, except to the extent such amendment, modification or waiver would
require the unanimous consent of the Lenders as described in Section 8.2.

(c) Benefit of Setoff. The Borrower agrees that each Participant shall be
deemed to have the right of setoff provided in Section 11.1 in respect of its
participating interest in amounts owing under the Facility Documents to the same extent as
if the amount of its participating interest were owing directly to it as a Lender under the
Facility Documents, provided that each Lender shall retain the right of setoff
provided in Section 11.1 with respect to the amount of participating interests sold
to each Participant. The Lenders agree to share with each Participant, and each
Participant, by exercising the right of setoff provided in Section 11.1, agrees to
share with each Lender, any amount received pursuant to the exercise of its right of setoff,
such amounts to be shared in accordance with Section 11.2 as if each Participant
were a Lender.

12.3 Assignments.

(a) Permitted Assignments. Any Lender may, in the ordinary course of its
business and in accordance with applicable law, at any time assign to one or more banks or
other entities (“Purchasers”) all or any part of its rights and obligations under
the Facility Documents. Such assignment shall be substantially in the form of
Exhibit B or in such other form as may be agreed to by the parties thereto. The
consent of the Borrower and the Agent shall be required prior to an assignment becoming
effective with respect to a Purchaser which is not a Lender or an Affiliate thereof;
provided, however, that if a Default has occurred and is continuing, the
consent of the Borrower shall not be required; provided, further, that the
Borrower shall be deemed to have consented to any such assignment unless it shall object
thereto by written notice to the Administrative Agent within five (5) Business Days after
having received notice thereto. Such consent shall not be unreasonably withheld or delayed.
Each such assignment shall (unless it is to a Lender or an Affiliate thereof or the Agent
otherwise consents) be in an amount not less than the lesser of (a) $5,000,000 or (b) the
remaining amount of the assigning Lender’s Letter of Credit Participation Amount (calculated
as at the date of such assignment).

(b) Effect; Effective Date. Upon (a) delivery to the Agent and the Borrower of
a notice of assignment, substantially in the form attached as Exhibit I to Exhibit B
(a “Notice of Assignment”), together with any consents required by
Section 12.3(b), and (b) payment of a $3,500 fee to the Agent by the assigning
Lender or the Purchaser for processing such assignment, such assignment shall become
effective on the effective date

 

- 62 -

 

specified in such Notice of Assignment. The Notice of
Assignment shall contain a representation by the Purchaser to the effect that none of the
consideration used to make the purchase of the participation interests in the Letters of
Credit under the applicable assignment agreement are “plan assets” as defined under ERISA
and that the rights and interests of the Purchaser in and under the Facility Documents will
not be “plan assets” under ERISA. On and after the effective date of such assignment, such
Purchaser shall for all purposes be a Lender party to this Agreement and any other Facility
Document executed by or on behalf of the Lenders and shall have all the rights and
obligations of a Lender under the Facility Documents, to the same extent as if it were an
original party hereto, and no further consent or action by the Borrower, the Lenders or the
Agent shall be required to release the transferor Lender with respect to the percentage of
the Letter of Credit Commitment and the participation interests in Letters of Credit
assigned to such Purchaser.

12.4 Dissemination of Information. The Borrower authorizes each Lender to disclose
to any Participant or Purchaser or any other Person acquiring an interest in the Facility
Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all
information in such Lender’s possession concerning the creditworthiness of the Borrower and its
Subsidiaries; provided that each Transferee and prospective Transferee agrees to be
bound by Section 9.11 of this Agreement.

12.5 Tax Treatment. If any interest in any Facility Document is transferred to any
Transferee which is organized under the laws of any jurisdiction other than the United States or
any State thereof, the transferor Lender shall cause such Transferee, concurrently with the
effectiveness of such transfer, to comply with the provisions of Section 3.5(d).

ARTICLE XIII

NOTICES

13.1 Notices. All notices, requests and other communications to any party
hereunder shall be in writing (including electronic transmission, facsimile transmission or
similar writing) and shall be given to such party: (a) in the case of the Borrower or the Agent,
at its address or facsimile number set forth on the signature pages hereof, (b) in the case of
any Lender, at its address or facsimile number set forth below its signature hereto or (c) in
the case of any party, at such other address or facsimile number as such party may hereafter
specify for the purpose by notice to the Agent and the Borrower in accordance with the
provisions of this Section 13.1. Each such notice, request or other communication shall
be effective (i) if given by facsimile transmission, when transmitted to the facsimile number
specified in this Section and confirmation of receipt is received, (ii) if given by mail,
seventy-two (72) hours after such communication is deposited in the mails with first class
postage prepaid, addressed as aforesaid, or (iii) if given by any other means, when delivered
(or, in the case of electronic transmission, received) at the address specified in this Section;
provided that notices to the Agent under Article II shall not be effective until

13.2 Change of Address. The Borrower, the Agent and any Lender may each change the
address for service of notice upon it by a notice in writing to the other parties hereto.

ARTICLE XIV

COUNTERPARTS

This Agreement may be executed in any number of counterparts, all of which taken together
shall constitute one agreement, and any of the parties hereto may execute this Agreement by signing
any such counterpart. This Agreement shall be effective when it has been executed by the Borrower,
the Agent and the Lenders and each party has notified the Agent by facsimile transmission or
telephone that it has taken such action.

ARTICLE XV

CHOICE OF LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL

15.1 CHOICE OF LAW. THE FACILITY DOCUMENTS (OTHER THAN THOSE CONTAINING A CONTRARY
EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS

BORROWER HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY
BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR
HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR
THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT OR
ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION.
ANY JUDICIAL PROCEEDING BY THE BORROWER AGAINST THE AGENT OR ANY LENDER OR ANY AFFILIATE OF THE
AGENT OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF,

For the purposes of this Schedule, the following terms have the following meanings, subject to
the final paragraph of this Schedule:

“Level I Status” exists at any date if, on such date, the Borrower’s S&P Rating is BBB+ or
better or the Borrower’s Moody’s Rating is Baa1 or better.

“Level II Status” exists at any date if, on such date, (i) the Borrower has not qualified for
Level I Status and (ii) the Borrower’s S&P Rating is BBB or better or the Borrower’s Moody’s Rating
is Baa2 or better.

“Level III Status” exists at any date if, on such date, (i) the Borrower has not qualified for
Level I Status or Level II Status and (ii) the Borrower’s S&P Rating is BBB- or better or the
Borrower’s Moody’s Rating is Baa3 or better.

“Level IV Status” exists at any date if, on such date, the Borrower has not qualified for
Level I Status, Level II Status or Level III Status.

“Status” means Level I Status, Level II Status, Level III Status or Level IV Status.

The Applicable Margin and Applicable Fee Rate shall be determined in accordance with the
foregoing table based on the Borrower’s Status as determined from its then-current Borrower’s S&P
Rating and Borrower’s Moody’s Rating; provided that if the Borrower’s S&P Rating and the Borrower’s
Moody’s Rating are not on the same Level, the better Rating shall apply except that if the Ratings
differ by more than one Level than the Level above the lower Rating shall apply. The Rating in
effect on any date for the purposes of this Schedule is that in effect at the close of business on
such date. If at any time the Borrower has only a Borrower’s S&P Rating or a Borrower’s Moody’s
Rating, the Borrower’s Status shall be determined from its then current Borrower’s S&P Rating or
Borrower’s Moody’s Rating, as the case may be. If at any time the Borrower has neither a
Borrower’s S&P Rating nor a Borrower’s Moody’s Rating, Level IV Status shall exist.
