PLAN ADMINISTRATION

	1.	 	Purpose of the Plan
	 
	 	 	The purpose of the Lifecore Biomedical (the Company) FY 2007 Bonus Plan (the Plan) is
to reward Executive Officers and selected members of the Management Team for the attainment
of corporate and individual objectives.
	 
	2.	 	Definitions
	 
	 	 	“Base Salary” means the plan participant’s salary in effect at the end of the plan
year.
	 
	 	 	“Committee” means the Compensation Committee of the Board.
	 
	 	 	“Threshold” means the minimum level of performance required to generate an award.
Threshold is 80% of the net income goal and 90% of the net sales goal.
	 
	 	 	“Plan” means the level of performance that reflects 100% attainment of the performance
measure approved by the Board. This level of performance triggers a target (or 100%) award.
	 
	 	 	“Maximum” means the level of performance that results in the maximum award available
under the plan being granted. Performance at maximum is 115% of the plan. Performance
beyond maximum will not increase the award.
	 
	 	 	“MBO” means Management By Objective. A discretionary award based on the attainment of
individual objectives.
	 
	3.	 	Plan Administrator
	 
	 	 	The Plan Administrator will be the Chairman of the Committee. The actions of the Plan
Administrator are subject to the approval of the Committee, as appropriate.
	 
	4.	 	Plan Administration
	 
	 	 	The Plan Administrator will administer the Plan under the general guidelines of this
document. This will include all matters pertaining to the Plan and its interpretation,
including the resolution of issues where the Plan is silent. Material matters are always
subject to the approval of the Committee.
	 
	5.	 	Participation
	 
	 	 	Participation will be restricted to Executive Officers and selected Management Team
members of the Company as recommended by the Plan Administrator and approved by the
Committee.

 

 

	 	 	The Committee will have full discretion to pay a bonus and to adjust the payment in
whatever manner the Committee deems appropriate to any individual who becomes an Executive
Officer or Management Team member of the Company during the fiscal year.
	 
	 	 	Participation in any one year does not guarantee participation in future years or
participation at the same award level.
	 
	6.	 	Bonus Award
	 
	 	 	Bonus payments under the Plan are specified under the attached Performance Parameters
based upon performance versus the FY 2007 Operating Plan. Bonus payments shall be
calculated on a pro rata basis using interpolation when performance is between parameters.
	 
	 	 	The Committee reserves the right to make discretionary bonus payments, subject to
approval by the Board of Directors, in the event the minimum performance level is not
attained. The fund for these discretionary payments shall not exceed 10% of annual base
salaries.
	 
	7.	 	Effective Date
	 
	 	 	The effective date of the Plan is July 1, 2006
	 
	8.	 	Plan Year
	 
	 	 	The Plan Year is the Company’s fiscal year.
	 
	9.	 	Termination of Employment
	 
	 	 	A Participant who terminates their employment or whose employment is terminated by the
Company forfeits all rights under the Plan.
	 
	 	 	The Committee will have full discretion to pay or not pay a bonus and to adjust the
payment in whatever manner the Committee deems appropriate.
	 
	10.	 	Death, Disability, Retirement
	 
	 	 	In the event of death, disability, or retirement, a prorated award will be made based
on the active time in the Plan and the level of performance attained. The Plan
Administrator may use discretion in determining awards under these circumstances.
	 
	11.	 	Employment
	 
	 	 	The Plan is not an employment contract, nor is there any intent to confer a right to
employment to a Plan Participant.
	 
	 	 	The Plan does not, in any way, restrict the Company’s right to terminate a
Participant’s employment.

2

 

	12.	 	Amendment to the Plan
	 
	 	 	The Committee may amend the Plan at any time. If such an amendment will materially
impact the Participants, they will be notified as soon as practical.
	 
	13.	 	Termination of the Plan
	 
	 	 	If the Plan is terminated, a pro rated award will be made based on the portion of the
plan year completed and the level of performance attained.
	 
	14.	 	Transferability
	 
	 	 	A Plan Participant may not sell, pledge, donate or otherwise assign their interest in
awards under the Plan.
	 
	15.	 	Legal Requirements

THE CREDIT

     Section 3.1 Commitments.

          (a) Each Bank severally agrees, subject to Section 3.1(c), Section 7.1 and
Section 7.2 and the other terms and conditions set forth in this Agreement, to lend to
Borrower from time to time prior to the Termination Date amounts requested by Borrower not to
exceed in the aggregate at any one time outstanding, the amount of such Bank’s Commitment reduced
by an amount equal to such Bank’s Letter of Credit Exposure. Each Borrowing shall be (i) in an
aggregate principal amount of $1,000,000 or any larger integral multiple of $100,000 (except that
any Base Rate Borrowing may be in an amount equal to the Availability at such time), and (ii) made
from the Banks ratably in accordance with their respective Commitment Percentages. Subject to the
foregoing limitations and the other provisions of this Agreement, prior to the Termination Date
Borrower may borrow under this Section 3.1(a), repay amounts borrowed and request new
Borrowings to be made under this Section 3.1(a). The Total Commitment as of the Closing
Date is the Initial Total Commitment.

          (b) Administrative Agent, or such Bank designated by Administrative Agent which (without
obligation to do so) consents to the same (“Letter of Credit Issuer”) will, from time to
time prior to the date which is five (5) Domestic Business Days prior to the Termination

26

 

Date, upon request by Borrower, issue Letters of Credit for the account of Borrower or any
Restricted Subsidiary designated by Borrower, so long as (i) the sum of (A) the total Letter of
Credit Exposure then existing, and (B) the amount of the requested Letter of Credit does not exceed
ten percent (10%) of the Borrowing Base then in effect (provided, that, in no event
shall such sum exceed the Total Commitment then in effect), and (ii) Borrower would be entitled to
a Borrowing under Section 3.1(a) and Section 3.1(c) in the amount of the requested
Letter of Credit. Not less than three (3) Domestic Business Days prior to the requested date of
issuance of any such Letter of Credit, Borrower (and any Restricted Subsidiary for whose account
such Letter of Credit is being issued) shall execute and deliver to Letter of Credit Issuer, Letter
of Credit Issuer’s customary letter of credit application. Each Letter of Credit shall be in the
minimum amount of $10,000 and shall be in form and substance acceptable to Letter of Credit Issuer.
No Letter of Credit shall have an expiration date later than the earlier of (1) one (1) year after
the Termination Date, or (2) one (1) year from the date of issuance (or, in the case of any renewal
or extension thereof, one (1) year after such renewal or extension). Upon the date of issuance of
a Letter of Credit, Letter of Credit Issuer shall be deemed to have sold to each other Bank, and
each other Bank shall be deemed to have unconditionally and irrevocably purchased from Letter of
Credit Issuer, a non recourse participation in the related Letter of Credit and Letter of Credit
Exposure equal to such Bank’s Commitment Percentage of such Letter of Credit and Letter of Credit
Exposure. Upon request of any Bank, but not less often than quarterly, Administrative Agent shall
provide notice to each Bank by telephone, teletransmission or telex setting forth each Letter of
Credit issued and outstanding pursuant to the terms hereof and specifying the beneficiary and
expiration date of each such Letter of Credit, each Bank’s percentage of each such Letter of Credit
and the actual dollar amount of each Bank’s participation held by Letter of Credit Issuer thereof
for such Bank’s account and risk. At the time of issuance of each Letter of Credit, Borrower shall
pay to Administrative Agent in respect of such Letter of Credit a) the applicable Letter of Credit
Fee, and b) the applicable Letter of Credit Fronting Fee. Administrative Agent shall distribute
the Letter of Credit Fee payable upon the issuance of each Letter of Credit to Banks in accordance
with their respective Commitment Percentages, and Administrative Agent shall distribute the Letter
of Credit Fronting Fee to Letter of Credit Issuer for its own account. Any 1) material amendment
or modification, or 2) renewal or extension of any Letter of Credit shall be deemed to be the
issuance of a new Letter of Credit for purposes of this Section 3.1(b). Notwithstanding
anything to the contrary contained herein, Borrower shall pay to Administrative Agent in connection
with the issuance of each Letter of Credit and/or any amendment or modification of any nature to
any existing Letter of Credit, Administrative Agent’s usual and customary fees for the issuance of,
amendments or modifications to, and processing of, Letters of Credit.

     Immediately upon the occurrence of an Event of Default and the acceleration of the Obligations
hereunder, and also on the date which is five (5) Domestic Business Days prior to the Termination
Date, Borrower shall deposit with Administrative Agent cash in such amounts as Administrative Agent
may request, up to a maximum amount equal to the aggregate existing Letter of Credit Exposure of
all Banks; provided, that, in the case of any of the Events of Default specified in
Section 12.1(g) or Section 12.1(h), an amount equal to the aggregate existing
Letter of Credit Exposure of all Banks shall be due and payable without any notice to Borrower or
any other act by Administrative Agent or any Bank. Any amounts so deposited shall be held by
Administrative Agent for the ratable benefit of all Banks as security for the outstanding Letter of
Credit Exposure and the other Obligations, and Borrower will, in connection therewith, execute

27

 

and deliver (and cause each other Credit Party to execute and deliver) such security
agreements in form and substance satisfactory to Administrative Agent which Administrative Agent
may, in its discretion, require. As drafts or demands for payment are presented under any Letter
of Credit, Administrative Agent shall apply such cash to satisfy such drafts or demands. When all
Letters of Credit have expired and the Obligations have been repaid in full (and no Bank has any
obligation to lend or issue Letters of Credit hereunder) or such Event of Default has been cured to
the satisfaction of Required Banks, Administrative Agent shall release to Borrower any remaining
cash deposited under this Section 3.1(b). Whenever Borrower is required to make deposits
under this Section 3.1(b) and fails to do so on the day such deposit is due, Administrative
Agent or any Bank may, without notice to Borrower, make such deposit (whether by application of
proceeds of any collateral for the Obligations, by transfers from other accounts maintained with
any Bank or otherwise) using any funds then available to any Bank of any Credit Party, any
guarantor or any other party liable for repayment of the Obligations.

     Notwithstanding anything to the contrary contained herein, Borrower hereby agrees to reimburse
each Letter of Credit Issuer immediately upon demand by such Letter of Credit Issuer, and in
immediately available funds, for any payment or disbursement made by such Letter of Credit Issuer
under any Letter of Credit issued by it. Payment shall be made by Borrower with interest on the
amount so paid or disbursed by Letter of Credit Issuer from and including the date payment is made
under any Letter of Credit to and including the date of payment, at the lesser of (i) the Maximum
Lawful Rate, or (ii) the Default Rate. The obligations of Borrower under this paragraph will
continue until all Letters of Credit have expired and all reimbursement obligations with respect
thereto have been paid in full by Borrower and until all other Obligations shall have been paid in
full.

     Borrower shall be obligated to reimburse Letter of Credit Issuer upon demand for all amounts
paid under Letters of Credit as set forth in the immediately preceding paragraph hereof;
provided, however, if Borrower for any reason fails to reimburse Letter of Credit
Issuer in full upon demand, Banks shall reimburse Letter of Credit Issuer in accordance with each
Banks’ Commitment Percentage for amounts due and unpaid from Borrower as set forth hereinbelow;
provided, however, that no such reimbursement made by Banks shall discharge
Borrower’s obligations to reimburse Letter of Credit Issuer. All reimbursement amounts payable by
any Bank under this Section 3.1(b) shall include interest thereon at the Federal Funds
Rate, from the date of the payment of such amounts by Letter of Credit Issuer to the date of
reimbursement by such Bank. No Bank shall be liable for the performance or nonperformance of the
obligations of any other Bank under this paragraph. The reimbursement obligations of Banks under
this paragraph shall continue after the Termination Date and shall survive termination of this
Agreement and the other Loan Papers.

     Borrower shall indemnify and hold Administrative Agent, Letter of Credit Issuer and each Bank,
and their respective officers, directors, representatives and employees harmless from loss for any
claim, demand or liability which may be asserted against any or such indemnified party in
connection with actions taken under Letters of Credit or in connection therewith (including losses
resulting from the negligence of any or such indemnified party), and shall pay each indemnified
party for reasonable fees of attorneys and legal costs paid or incurred by each indemnified party
in connection with any matter related to Letters of Credit, except for losses and liabilities
incurred as a direct result of the gross negligence or willful misconduct of such

28

 

indemnified party, IT BEING THE EXPRESS INTENTION OF THE PARTIES THAT EACH INDEMNIFIED PARTY
SHALL BE INDEMNIFIED FOR THE CONSEQUENCES OF ITS OWN ORDINARY NEGLIGENCE. If Borrower for any
reason fails to indemnify or pay such indemnified party as set forth herein in full, Banks shall
indemnify and pay such indemnified party upon demand, in accordance with each Bank’s Commitment
Percentage of such amounts due and unpaid from Borrower; provided, however, that,
no such payment made by Banks shall discharge Borrower’s obligation to indemnify or pay such
indemnified party in accordance with the terms hereof. The provisions of this paragraph shall
survive the termination of this Agreement.

     Neither Administrative Agent nor any other Letter of Credit Issuer makes any representation or
warranty, nor assumes any responsibility with respect to the validity, legality, sufficiency or
enforceability of any letter of credit application executed and delivered in connection with any
Letter of Credit issued hereunder or any document relative thereto or to the collectibility
thereunder. Neither Administrative Agent nor any other Letter of Credit Issuer assumes any
responsibility for the financial condition of Borrower or for the performance of any obligation of
Borrower. Administrative Agent and each other Letter of Credit Issuer may use its discretion with
respect to exercising or refraining from exercising any rights, or taking or refraining from taking
any action which may be vested in it or which it may be entitled to take or assert with respect to
any Letter of Credit or any letter of credit application. FURTHERMORE, EXCEPT AS SET FORTH HEREIN,
NEITHER ADMINISTRATIVE AGENT NOR ANY OTHER LETTER OF CREDIT ISSUER SHALL BE UNDER ANY LIABILITY TO
ANY BANK, WITH RESPECT TO ANYTHING ADMINISTRATIVE AGENT OR ANY SUCH LETTER OF CREDIT ISSUER MAY DO
OR REFRAIN FROM DOING IN THE EXERCISE OF ITS JUDGMENT, THE SOLE LIABILITY AND RESPONSIBILITY OF
ADMINISTRATIVE AGENT AND SUCH LETTER OF CREDIT ISSUER BEING TO HANDLE EACH BANK’S SHARE ON AS
FAVORABLE A BASIS AS ADMINISTRATIVE AGENT OR SUCH LETTER OF CREDIT ISSUER HANDLES ITS OWN SHARE.
NEITHER ADMINISTRATIVE AGENT NOR ANY OTHER LETTER OF CREDIT ISSUER SHALL HAVE ANY DUTIES OR
RESPONSIBILITIES EXCEPT THOSE EXPRESSLY SET FORTH HEREIN AND THOSE DUTIES AND LIABILITIES SHALL BE
SUBJECT TO THE LIMITATIONS AND QUALIFICATIONS SET FORTH HEREIN. FURTHERMORE, NEITHER ADMINISTRATIVE
AGENT, ANY LETTER OF CREDIT ISSUER, NOR ANY OF THEIR DIRECTORS, OFFICERS, OR EMPLOYEES SHALL BE
LIABLE FOR ANY ACTION TAKEN OR OMITTED (WHETHER OR NOT SUCH ACTION TAKEN OR OMITTED IS EXPRESSLY
SET FORTH HEREIN) UNDER OR IN CONNECTION HEREWITH OR UNDER ANY OTHER INSTRUMENT OR DOCUMENT IN
CONNECTION HEREWITH, EXCEPT FOR GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. Neither Administrative
Agent nor any other Letter of Credit Issuer shall incur any liability to any Bank, Borrower, or any
Affiliate of any Bank or Borrower, in acting upon any notice, document, order, consent,
certificate, warrant or other instrument reasonably believed by Administrative Agent or such Letter
of Credit Issuer to be genuine or authentic and to be signed by the proper party.

          (c) No Bank will be obligated to lend to Borrower hereunder or incur Letter of Credit
Exposure, and Borrower shall not be entitled to borrow hereunder or obtain Letters of Credit
hereunder, in an amount which would cause, after giving effect to the making of any

29

 

Revolving Loan or issuance of any Letter of Credit (i) the sum of the aggregate principal
balance of such Bank’s Revolving Loans on such date plus its Commitment Percentage of the Letter of
Credit Exposure on such date, to exceed its Commitment, or (ii) the Outstanding Credit to exceed
the lesser of (A) the Borrowing Base then in effect, or (B) the Total Commitment then in effect.
No Bank shall be obligated to fund Borrowings hereunder and Borrower shall not be entitled to
Borrowings hereunder during the existence of a Borrowing Base Deficiency. Nothing in this
Section 3.1(c) shall be deemed to limit any Bank’s obligation to reimburse any Letter of
Credit Issuer with respect to its participation in Letters of Credit as a result of the drawing
under any Letter of Credit pursuant to Section 3.1(b).

     Section 3.2 Method of Borrowing.

any applicable condition precedent set forth in Section 7.2 hereof has not been satisfied,
Administrative Agent or such other applicable Letter of Credit Issuer will issue and deliver such
Letter of Credit pursuant to the instructions of Borrower.

     Section 3.4 Notes. Each Bank’s Commitment Percentage of the Revolving Loan shall be
evidenced by a single Note payable to the order of such Bank in an amount equal to such Bank’s
Commitment.

     Section 3.5 Interest Rates; Payments.

          (a) The principal amount of the Base Rate Loan outstanding from day to day shall bear interest
at a rate per annum equal to the sum of (i) the Applicable Margin plus (ii) the applicable Base
Rate in effect from day to day; provided that in no event shall the rate charged
hereunder or under the Notes exceed the Maximum Lawful Rate. Interest on the Base Rate Loan shall
be payable as it accrues on each Quarterly Date, and on the Termination Date.

          (b) The principal amount of each Eurodollar Loan outstanding from day to day shall bear
interest for the Interest Period applicable thereto at a rate per annum equal to the sum of (i) the
Applicable Margin plus (ii) the applicable Adjusted Eurodollar Rate; provided that
in no event shall the rate charged hereunder or under the Notes exceed the Maximum Lawful Rate.
Interest on any portion of the principal of each Eurodollar Loan subject to an Interest Period of
one (1), two (2) or three (3) months shall be payable on the last day of the Interest Period
applicable thereto. Interest on any portion of the principal of each Eurodollar Loan

31

 

subject to an Interest Period of six (6), nine (9), or twelve (12) months shall be payable on
the last day of the Interest Period applicable thereto and on each Quarterly Date.

          (c) So long as no Default or Event of Default shall be continuing, subject to the provisions
of this Section 3.5, Borrower shall have the option of having all or any portion of the
principal outstanding under the Revolving Loan be a Base Rate Loan or one (1) or more Eurodollar
Loans, which shall bear interest at rates determined by reference to the Base Rate and the Adjusted
Eurodollar Rate, respectively; provided, that each Eurodollar Loan shall be in a
minimum amount of $2,000,000 and shall be in an amount which is an integral multiple of $500,000.
Prior to the termination of each Interest Period with respect to each Eurodollar Loan, Borrower
shall give written notice (a “Notice of Continuation or Conversion”) in the form of Exhibit
H attached hereto to Administrative Agent of the Type of Loan which shall be applicable to the
principal of such Eurodollar Loan upon the expiration of such Interest Period. Such Notice of
Continuation or Conversion shall be given to Administrative Agent at least one (1) Domestic
Business Day, in the case of a Base Rate Loan selection and three (3) Eurodollar Business Days, in
the case of a Eurodollar Loan selection, prior to the termination of the Interest Period then
expiring. If Borrower shall specify a Eurodollar Loan, such Notice of Continuation or Conversion
shall also specify the length of the succeeding Interest Period (subject to the provisions of the
definition of such term) selected by Borrower. Each Notice of Continuation or Conversion shall be
irrevocable and effective upon notification thereof to Administrative Agent. If the required
Notice of Continuation or Conversion shall not have been timely received by Administrative Agent,
Borrower shall be deemed to have elected that the principal of the Eurodollar Loan subject to the
Interest Period then expiring be Converted to the Base Rate Loan upon the expiration of such
Interest Period and Borrower will be deemed to have given Administrative Agent notice of such
election. Subject to the limitations set forth in this Section 3.5(c) on the amount and
number of Eurodollar Loans, Borrower shall have the right to Convert all or any part of the Base
Rate Loan to a Eurodollar Loan by giving Administrative Agent a Notice of Continuation or
Conversion of such election at least three (3) Eurodollar Business Days prior to the date on which
Borrower elects to make such Conversion (a “Conversion Date”). The Conversion Date
selected by Borrower shall be a Eurodollar Business Day. Notwithstanding anything in this
Section 3.5 to the contrary, no portion of the principal of the Base Rate Loan may be
Converted to a Eurodollar Loan and no Eurodollar Loan may be Continued as such when any Default or
Event of Default has occurred and is continuing, but each such Eurodollar Loan shall be
automatically Converted to the Base Rate Loan on the last day of each applicable Interest Period.
Borrower shall not be permitted to have more than seven (7) Eurodollar Loans in effect at any time.

          (d) Notwithstanding anything to the contrary set forth in Section 3.5(a) or
Section 3.5(b) above, after the occurrence of an Event of Default, interest shall accrue on
the outstanding principal balance of the Revolving Loan, and to the extent permitted by Law, on the
accrued but unpaid interest on the Revolving Loan and all other Obligations from the period from
and including the occurrence of such Event of Default to but excluding the date the same is
remedied at a rate per annum equal to the lesser of (i) the Default Rate, and (ii) the Maximum
Lawful Rate.

          (e) Administrative Agent shall determine each interest rate applicable to the Revolving Loan
in accordance with the terms hereof. Administrative Agent shall promptly

32

 

notify Borrower and Banks by telex, telecopy or cable of each rate of interest so determined,
and its determination thereof shall be conclusive in the absence of manifest error.

          (f) Notwithstanding the foregoing, if at any time the rate of interest calculated with
reference to the Base Rate or the Eurodollar Rate hereunder (the “contract rate”) is
limited to the Maximum Lawful Rate, any subsequent reductions in the contract rate shall not reduce
the rate of interest on the Revolving Loan below the Maximum Lawful Rate until the total amount of
interest accrued equals the amount of interest which would have accrued if the contract rate had at
all times been in effect. In the event that at maturity (stated or by acceleration), or at final
payment of any Note, the total amount of interest paid or accrued on such Note is less than the
amount of interest which would have accrued if the contract rate had at all times been in effect
with respect thereto, then at such time, to the extent permitted by Law, Borrower shall pay to the
holder of such Note an amount equal to the difference between (i) the lesser of the amount of
interest which would have accrued if the contract rate had at all times been in effect and the
amount of interest which would have accrued if the Maximum Lawful Rate had at all times been in
effect, and (ii) the amount of interest actually paid on such Note.

          (g) Interest payable hereunder on each Eurodollar Loan shall be computed based on the number
of actual days elapsed assuming that each calendar year consisted of 360 days. Interest payable
hereunder on the Base Rate Loan shall be computed based on the actual number of days elapsed
assuming that each calendar year consisted of 365 days (or 366 days in a leap year).

     Section 3.6 Mandatory Prepayments. Upon the occurrence of any Borrowing Base
Deficiency, Borrower shall make the mandatory prepayments of the Revolving Loan required by
Section 5.4 hereof. Additionally, if at any time the Outstanding Credit is in excess of
the Total Commitment (as used in this Section 3.6, a “deficiency”), Borrower shall
immediately make a principal payment on the Revolving Loan sufficient to cause the principal
balance of the Revolving Loan then outstanding to be equal to or less than the Total Commitment
then in effect. If a deficiency cannot be eliminated pursuant to this Section 3.6 by
prepayment of the Revolving Loan (as a result of outstanding Letter of Credit Exposure), Borrower
shall also deposit cash with Administrative Agent, to be held by Administrative Agent to secure
outstanding Letter of Credit Exposure in the manner contemplated by Section 3.1(b).

     Section 3.7 Voluntary Prepayments. Borrower may, subject to Section 14.5 and
the other provisions of this Agreement, prepay the principal of the Revolving Loan in whole or in
part. Any partial prepayment shall be in a minimum amount of $500,000 and shall be in an integral
multiple of $100,000.

     Section 3.8 Voluntary Reduction of Commitments. Borrower may, by notice to
Administrative Agent five (5) Domestic Business Days prior to the effective date of any such
reduction, reduce the Total Commitment (and thereby reduce the Commitment of each Bank ratably) in
amounts not less than $5,000,000 and in an amount which is an integral multiple of $1,000,000. On
the effective date of any such reduction, Borrower shall, to the extent required as a result of
such reduction, make a principal payment on the Revolving Loan in an amount sufficient to cause the
principal balance of the Revolving Loan then outstanding to be equal to or less than the Total
Commitment as thereby reduced. Notwithstanding the foregoing, Borrower

33

 

shall not be permitted to voluntarily reduce the Total Commitment to an amount less than the
aggregate Letter of Credit Exposure of all Banks.

     Section 3.9 Termination of Commitments; Final Maturity of Revolving Loan. The Total
Commitment (and the Commitment of each Bank) shall terminate, and the entire outstanding principal
balance of the Revolving Loan, all interest accrued thereon, all accrued but unpaid fees hereunder
and all other outstanding Obligations shall be due and payable in full on the Termination Date.

     Section 3.10 Voluntary Increase of Total Commitment. So long as no Default or Event
of Default has occurred and is continuing, and so long as no Borrowing Base Deficiency exists,
Borrower shall have the right to increase the Total Commitment by increasing the existing
Commitments and/or obtaining additional Commitments (the amount of such increase is herein called
the “Commitment Increase”), either from (a) one or more of the Banks, or (b) another
financial institution; provided, that (i) Borrower shall have notified
Administrative Agent (which shall promptly deliver a copy to each Bank) in writing of the amount of
the Commitment Increase, (ii) each Bank shall have had the option to increase its Commitment up to
its pro rata share (such pro rata share to be computed prior to the addition of any new Bank under
the terms of this Section 3.10 and Section 15.10(f) hereof) of the Commitment
Increase within ten (10) Domestic Business Days following receipt of notice from Administrative
Agent pursuant to clause (i) above, (iii) Administrative Agent shall have approved any new
Bank (such approval not to be unreasonably withheld after giving effect to the terms of clause
(ii) hereof), (iv) any such new Bank shall have assumed all of the rights and obligations
of a “Bank” hereunder, (v) the procedure described in Section 15.10(f) shall have been
complied with, (vi) first and prior Liens (subject only to Permitted Encumbrances) shall have been
created by Mortgages in favor of Administrative Agent encumbering Borrowing Base Properties
comprising the Minimum Collateral Amount after giving effect to the Commitment Increase, and (vii)
after giving effect to the Commitment Increase, the Total Commitment shall not exceed the Borrowing
Base then in effect. Notwithstanding anything to the contrary contained herein, the Commitment of
any Bank may not be increased without the prior written consent of such Bank.

     Section 3.11 Application of Payments. Each repayment pursuant to Section 3.6,
Section 3.7, Section 3.8, Section 3.9 and Section 5.4 shall be made
together with accrued interest on the amount repaid to the date of payment, and shall be applied in
accordance with Section 4.2 and the other provisions of this Agreement.

     Section 3.12 Commitment Fee. On the Termination Date, on each Quarterly Date prior to
the Termination Date, and, in the event the Commitments are terminated in their entirety prior to
the Termination Date, on the date of such termination, Borrower shall pay to Administrative Agent,
for the ratable benefit of each Bank based on each Bank’s Commitment Percentage, a commitment fee
equal to the Commitment Fee Percentage in effect from day to day (applied on a per annum basis and
computed on the basis of actual days elapsed and as if each calendar year consisted of 365 days (or
366 days in a leap year)) of the average daily Availability for the Fiscal Quarter (or portion
thereof) ending on the date such payment is due.

     Section 3.13 Agency and other Fees. Borrower shall pay to Administrative Agent and
its Affiliates such other fees and amounts as Borrower shall be required to pay to Administrative

34

 

Agent and its Affiliates from time to time pursuant to any separate agreement between Borrower
and Administrative Agent or such Affiliates. Such fees and other amounts shall be retained by
Administrative Agent and its Affiliates, and no Bank (other than JPMorgan) shall have any interest
therein. Administrative Agent may disburse any fees paid to Administrative Agent and its
Affiliates pursuant to this Section 3.13 in any manner Administrative Agent desires in its
sole discretion.

ARTICLE IV

GENERAL PROVISIONS

     Section 4.1 Delivery and Endorsement of Notes. On the Closing Date, Administrative
Agent shall deliver to each Bank the Note payable to such Bank. Each Bank may endorse (and prior
to any transfer of its Note shall endorse) on the schedules attached and forming a part thereof
appropriate notations to evidence the date and amount of its Commitment Percentage of each
Borrowing, the Interest Period applicable thereto, and the date and amount of each payment of
principal made by Borrower with respect thereto; provided that the failure by any
Bank to so endorse its Note shall not affect the liability of Borrower for the repayment of all
amounts outstanding under such Note together with interest thereon. Each Bank is hereby
irrevocably authorized by Borrower to endorse its Note and to attach to and make a part of any such
Note a continuation of any such schedule as required.

     Section 4.2 General Provisions as to Payments.

          (a) Borrower shall make each payment of principal of, and interest on, the Revolving Loan, and
all fees payable hereunder shall be paid, not later than 12:00 noon (Chicago, Illinois time) on the
date when due, in Federal or other funds immediately available in Chicago, Illinois, to
Administrative Agent at its address set forth on Schedule 2.1 hereto, without defense,
set-off, deduction or counterclaim. Administrative Agent will promptly (and if such payment is
received by Administrative Agent by 10:00 a.m. (Chicago, Illinois time), and otherwise if
reasonably possible, on the same Domestic Business Day) distribute to each Bank its Commitment
Percentage of each such payment received by Administrative Agent for the account of Banks.
Whenever any payment of principal of, or interest on, the Base Rate Loan or of fees shall be due on
a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the
next succeeding Domestic Business Day. Whenever any payment of principal of, or interest on, any
portion of any Eurodollar Loan shall be due on a day which is not a Eurodollar Business Day, the
date for payment thereof shall be extended to the next succeeding Eurodollar Business Day (subject
to the provisions of the definition of Interest Period). If the date for any payment of principal
is extended by operation of Law or otherwise, interest thereon shall be payable for such extended
time. Borrower hereby authorizes Administrative Agent to charge from time to time against
Borrower’s accounts with Administrative Agent any amount then due.

          (b) Prior to the occurrence of an Event of Default, all principal payments received by Banks
with respect to the Revolving Loan shall be applied first to Eurodollar Loans outstanding with
Interest Periods ending on the date of such payment, then to the Base Rate Loan, and then to
Eurodollar Loans next maturing until such principal payment is fully applied.

35

 

          (c) After the occurrence of an Event of Default, all amounts collected or received by
Administrative Agent or any Bank shall be applied first to the payment of all proper costs incurred
by Administrative Agent in connection with the collection thereof (including reasonable expenses
and disbursements of Administrative Agent), second to the payment of all proper costs incurred by
Banks in connection with the collection thereof (including reasonable expenses and disbursements of
Banks), third to the reimbursement of any advances made by Banks to effect performance of any
unperformed covenants of any Credit Party under any of the Loan Papers, fourth to the payment of
any unpaid fees required pursuant to Section 3.13, fifth to the payment of any unpaid fees
required pursuant to Section 3.1(b) and Section 3.12, sixth, to the payment of all

obligations and liabilities then due under Hedge Agreements, such payments to be made pro rata to
each Bank (and/or its Affiliates) owed such Obligations in proportion to all such payments owed to
all Banks (and/or its Affiliates) in respect of such Obligations, and eighth, to establish the
deposits required in Section 3.1(b). All payments received by a Bank after the occurrence
of an Event of Default for application to the principal of the Revolving Loan shall be applied by
such Bank in the manner provided in Section 4.2(b).

ARTICLE V

BORROWING BASE

     Section 5.1 Reserve Report; Proposed Borrowing Base. The aggregate amount of credit
available to Borrower under this Agreement shall be limited by a Borrowing Base (herein so called)
which shall be determined by Banks at the times and in accordance with the standards and procedures
set forth in this Article V. As soon as available and in any event by February 28 and
August 31 of each year commencing February 28, 2007, Borrower shall deliver to Administrative Agent
and each Bank a Reserve Report prepared as of the immediately preceding December 31 and June 30
respectively. Simultaneously with the delivery to Administrative Agent and each Bank of each
Reserve Report, Borrower shall notify Administrative Agent and each Bank of the amount of the
Borrowing Base which Borrower requests become effective on the next Redetermination Date (or such
date promptly following such Redetermination Date as Required Banks shall elect).

     Section 5.2 Scheduled Redeterminations of the Borrowing Base; Procedures and
Standards. Based in part on the Reserve Reports made available to Banks pursuant to
Section 5.1, Banks shall redetermine the Borrowing Base on or prior to the next
Redetermination Date (or such date promptly thereafter as reasonably possible based on the
engineering and other information available to Banks). Any Borrowing Base which becomes effective
as a result of any Redetermination of the Borrowing Base shall be subject to the following
restrictions: (a) such Borrowing Base shall not exceed the Borrowing Base requested by Borrower
pursuant to Section 5.1 or Section 5.3 (as applicable), (b) such Borrowing Base
shall not exceed the Maximum Total Commitment Amount, (c) to the extent such Borrowing Base
represents an increase from the Borrowing Base in effect prior to such Redetermination, such
Borrowing Base shall be approved by all Banks, and (d) to the extent such Borrowing Base represents
a decrease in the Borrowing Base in effect prior to such Redetermination, or a reaffirmation of
such prior Borrowing Base, such Borrowing Base shall be approved by Required Banks. Each
Redetermination shall be made by Banks in their sole discretion. Without limiting such

36

 

discretion, Parent and Borrower acknowledge and agree that Banks (i) may make such assumptions
regarding appropriate existing and projected pricing for Hydrocarbons as they deem appropriate in
their sole discretion, (ii) may make such assumptions regarding projected rates and quantities of
future production of Hydrocarbons from the Mineral Interests owned by Borrower as they deem
appropriate in their sole discretion, (iii) may consider the projected cash requirements of the
Credit Parties, (iv) are not required to consider any asset other than Proved Mineral Interests
owned by Borrower which are subject to first and prior Liens in favor of Administrative Agent for
the ratable benefit of Banks to the extent required by Section 6.1 hereof, and (v) may make
such other assumptions, considerations and exclusions as Banks deem appropriate in the exercise of
their sole discretion. It is further acknowledged and agreed that each Bank may consider such
other credit factors as it deems appropriate in the exercise of its sole discretion and shall have
no obligation in connection with any Redetermination to approve any increase from the Borrowing
Base in effect prior to such Redetermination. Promptly following any Redetermination of the
Borrowing Base, Administrative Agent shall notify Borrower of the amount of the Borrowing Base as
redetermined, which Borrowing Base shall be effective as of the date specified in such notice, and
shall remain in effect for all purposes of this Agreement until the next Redetermination.

     Section 5.3 Special Redetermination.

          (a) In addition to Scheduled Redeterminations, Borrower and Required Banks shall each be
permitted to request a Special Redetermination of the Borrowing Base once in each Fiscal Year. Any
request by Required Banks pursuant to this Section 5.3(a) shall be submitted to
Administrative Agent and Borrower. Any request by Borrower pursuant to this Section 5.3(a)
shall be submitted to Administrative Agent and each Bank and at the time of such request Borrower
shall (i) deliver to Administrative Agent and each Bank a Reserve Report, and (ii) also notify
Administrative Agent and each Bank of the Borrowing Base requested by Borrower in connection with
such Special Redetermination.

          (b) Any Special Redetermination shall be made by Banks in accordance with the procedures and
standards set forth in Section 5.2; provided, that, no Reserve Report will
be required to be delivered to Administrative Agent and Banks in connection with any Special
Redetermination requested by Required Banks pursuant to Section 5.3(a) above.

     Section 5.4 Borrowing Base Deficiency. To the extent a Borrowing Base Deficiency
exists after giving effect to any Redetermination, Borrower shall be obligated to eliminate such
Borrowing Base Deficiency over a period not to exceed six (6) months from the effective date of
such Redetermination by making six (6) mandatory, equal, consecutive, monthly payments of principal
on the Revolving Loan, each of which shall be in the amount of one sixth (1/6th) of such Borrowing
Base Deficiency, or in the event that the remaining principal outstanding under the Revolving Loan
is less than the Borrowing Base Deficiency, then in the amount of one sixth (1/6th) of the
remaining principal outstanding under the Revolving Loan. The first of such six (6) payments shall
be due on the thirtieth (30th) day following the effective date of each such Redetermination and
each subsequent payment shall be due on the same day of each month thereafter (or if there is no
corresponding day of any subsequent month, then on the last day of such month) (each such date is
referred to herein as a “borrowing base deficiency payment date”). If a Borrowing Base
Deficiency cannot be eliminated pursuant to this Section 5.4 by

37

 

prepayment of the Revolving Loan in full (as a result of outstanding Letter of Credit
Exposure), on each borrowing base deficiency payment date, Borrower shall also deposit cash with
Administrative Agent, to be held by Administrative Agent to secure outstanding Letter of Credit
Exposure in the manner contemplated by Section 3.1(b), an amount at least equal to one
sixth (1/6th) of the balance of such Borrowing Base Deficiency (i.e., one-sixth of the difference
between the Borrowing Base Deficiency and the remaining outstanding principal under the Revolving
Loan on the effective date of such Redetermination).

     Section 5.5 Initial Borrowing Base. Notwithstanding anything to the contrary
contained herein, the Borrowing Base in effect during the period commencing on the Closing Date and
ending on the effective date of the first Redetermination after the Closing Date shall be the
Initial Borrowing Base.

deliver Mortgages and/or Amendments to Mortgages to Administrative Agent pursuant to this
Section 6.1, Borrower shall also deliver to Administrative Agent such opinions of counsel

and other evidence of title as Administrative Agent shall deem necessary or appropriate to verify
(i) Parent’s, Borrower’s or such Restricted Subsidiary’s title to the Borrowing Base Properties
comprising the Minimum Collateral Amount which are subject to such Mortgages, and (ii) the
validity, perfection and priority of the Liens created by such Mortgages (as amended by the
Amendments to Mortgages, as applicable) and such other matters regarding such Mortgages as
Administrative Agent shall reasonably request.

Subsidiary pursuant to the terms of Section 10.2(b), each Restricted Subsidiary pursuant to

services, materials and supplies) for sums which have become due and payable and which by Law have
or might become a Lien (other than a Permitted Encumbrance) on any of its assets; provided,

or validity thereof is currently being contested in good faith by appropriate action promptly
initiated and diligently conducted in accordance with good business practices and no material part
of the property or assets of Parent or Borrower, and no part of the assets of any Restricted
Subsidiary which would be material to Parent or Borrower, is subject to any pending levy or
execution, (ii) Parent, Borrower, and any Restricted Subsidiary, as and to the extent required in
accordance with GAAP, shall have set aside on their books reserves (segregated to

Adverse Effect.

          (b) Parent and Borrower will, and will cause each other Credit Party to, comply in all
respects with all contracts and agreements applicable to or relating to its Mineral Interests or
the production and sale of Hydrocarbons and accompanying elements therefrom, except to the extent a

maintain, preserve and keep all operating equipment used with respect to its Mineral Interests in
proper repair, working order and condition, and make all necessary or appropriate repairs,
renewals, replacements, additions and improvements thereto so that the efficiency of such operating
equipment shall at all times be properly preserved and maintained, except where such failure to
comply would not have a Material Adverse Effect; provided, further that, no
item of operating equipment need be so repaired, renewed, replaced, added to or improved, if
Borrower shall in good faith determine that such action is not necessary or desirable for the
continued efficient and profitable operation of the business of such Credit Party.

     Section 9.10 Environmental Law Compliance. Except to the extent a failure to comply
would not have a Material Adverse Effect, Parent and Borrower will, and will cause each other

Party to, hedge (which hedges shall not have a term of greater four (4) years) more than the
following percentages of its “forecasted production from Proved Mineral Interests” (as defined
below) during any applicable calendar year (a “measurement period”), as measured from the
current date (a “measurement date”):

	 	 	 	 	 	 	 	 	 
	Calendar Year Hedged	 	Percentage Limitation
	(relative to measurement date)	 	Oil	 	Gas
	Current Year
	 	 	85	%	 	 	85	%
	First Subsequent Year
	 	 	70	%	 	 	70	%
	Second Subsequent Year
	 	 	55	%	 	 	55	%
	Third Subsequent Year
	 	 	40	%	 	 	40	%

provided, that, if any measurement date occurs in the final two Fiscal Quarters of
any measurement period, for the purpose of determining the appropriate percentage limitation from
the table above, the limitations of the current year shall apply to both the remaining portion of
that current year and the entire subsequent year, and the limitations of the first subsequent year
shall apply to the second subsequent year (as an example only, and for the avoidance of doubt, for
any measurement date occurring during the first two Fiscal Quarters of 2007, an Oil and Gas Hedge
Transaction for 2008 would have a 70% limitation; provided, however, for any
measurement date occurring during the last two Fiscal Quarters of 2007, an Oil and Gas Hedge
Transaction for 2008 would have an 85% limitation); provided, further,
that, Borrower may enter into Hedge Transactions consisting solely of a floor price (i.e.
floor, put or option) so long as the amount of Hydrocarbons which are the subject of any such Hedge
Transaction in existence at any such time do not exceed one-hundred percent (100%) of Borrower’s
anticipated production from Proved Mineral Interests during the term of any such existing Hedge
Transaction; and

          (b) Borrower will not permit its (i) production of oil during any Fiscal Quarter to be less
than the aggregate amount of oil which is the subject of Oil and Gas Hedge Transactions during such
Fiscal Quarter, or (ii) production of gas during any Fiscal Quarter to be less than the aggregate
amount of gas which is the subject of Oil and Gas Hedge Transactions during such Fiscal Quarter.

     As used in Section 10.11 above, “forecasted production from Proved Mineral
Interests” shall mean the forecasted production for oil and gas, each taken individually, for
the applicable calendar year as reflected in the most recent Reserve Report delivered to
Administrative Agent pursuant to Section 5.1 hereof, after giving effect to any pro forma
adjustments for the consummation of any “material acquisitions or dispositions” between the
effective date of such Reserve Report and the measurement date. “Material acquisitions or 

59

 

dispositions” means any acquisition or disposition of any Borrowing Base Property
with a Recognized Value in excess of $25,000,000, or any cumulative total of all immaterial
acquisitions or dispositions which in the aggregate have a Recognized Value in excess of
$25,000,000.

Permitted Genesis VPP Transactions, and (b) additional transactions between Genesis and Borrower
which (i) are in the ordinary course of business of Borrower and Genesis, (ii) are on fair and
reasonable terms and at prices which are fully disclosed to Administrative Agent and are no less
favorable to Borrower (economically or otherwise) than would be obtained in a comparable arm’s
length transaction with a Person not an Affiliate, and (iii) otherwise comply with the terms of
this Agreement, Parent and Borrower will not, nor will Parent and/or Borrower permit any other
Credit Party to, incur any liability, Debt or obligation to any Unrestricted Subsidiary of any
nature, or have any liability (whether by operation of law or otherwise) for any liability, Debt or
obligation of any Unrestricted Subsidiary.

     Section 10.15 Borrowings Related to Bonds. Borrower will not request or receive any
Borrowing hereunder, the proceeds of which are to be used to fund advances under the 2005 Bonds or
any Additional Permitted Revenue Bonds, except in accordance and in compliance with the terms of
the applicable Bond Documents. Borrower agrees that each Request for Borrowing, the proceeds of
which are to be used to fund advances under the 2005 Bonds or any Additional Permitted Revenue
Bonds, will include, in addition to the information described in Section 3.2 hereof, a
certification from an Authorized Officer as to the purpose and utilization of the proceeds of such
Borrowing. Additionally, notwithstanding anything to the contrary contained in the Loan Papers or
Bond Documents, each payment of principal and interest received by Bond Purchaser on the 2005 Bonds
or any Additional Permitted Revenue Bonds shall be deemed to be and considered as, without
duplication, a payment of principal and interest on the Revolving Loan, and any borrowing by
Borrower under the 2005 Bond Loan Agreement or any loan agreement hereafter entered into in
connection with any Additional Permitted Revenue Bond Transaction, or on any 2005 Bond Note or any
promissory note hereafter executed in connection with any Additional Permitted Revenue Bond
Transaction shall also be deemed to be and considered as, without duplication, a Borrowing of a
Revolving Loan hereunder (the outstanding principal of which shall be and be deemed to be included
in the Outstanding Credit for all purposes hereunder).

     Section 10.16 Speculative Hedge Transactions. Parent and Borrower will not, nor will
Parent and/or Borrower permit any other Credit Party to, enter into any commodity, interest rate,
currency or other swap, option, collar or other derivative transaction pursuant to which Parent,
Borrower or such other Credit Party speculates on the movement of commodity prices, securities
prices, interest rates, financial markets, currency markets or other items; provided,
that, nothing

60

 

contained in this Section 10.16 shall prohibit Borrower from entering into Hedge
Transactions permitted by Section 10.11.

     Section 10.17 Permitted Subordinate Debt Documents. Parent and Borrower will not, nor
will Parent and Borrower permit any other Credit Party to:

          (a) amend, modify or waive any covenant in any of the Permitted Subordinate Debt Documents if
the effect of such amendment, modification or waiver would be to make the terms of any such
Permitted Subordinate Debt Document materially more onerous to any Credit Party;

          (b) amend, modify or waive any provision of any Permitted Subordinate Debt Document if the
effect of such amendment, modification or waiver (i) subjects a Credit Party to any additional
material obligation, (ii) increases the principal of any Permitted Subordinate Debt or increases
the rate of interest on any note evidencing any Permitted Subordinate Debt to a rate in excess of
nine percent (9%), (iii) accelerates the date fixed for any payment of principal or interest on any
note evidencing any Permitted Subordinate Debt to a date sooner than the date which is one year
following the earlier of (A) the Termination Date, and (B) the date on which there are no Revolving
Loans, Letter of Credit Exposure or other Obligations hereunder outstanding and all of the
Commitments are terminated, or (iv) would change the percentage of holders of such notes evidencing
any Permitted Subordinate Debt required for any such amendment, modification or waiver from the
percentage required on the date of issuance of any such notes evidencing any Permitted Subordinate
Debt; or

          (c) make any payment of principal of, make any voluntary prepayment of, or optionally redeem,
or make any payment in defeasance of, all or any portion of any Permitted Subordinate Debt;
provided, that, so long as no Default or Borrowing Base Deficiency exists on the
date of any such redemption, and no Default or Borrowing Base Deficiency would result therefrom,
Parent and/or Borrower may redeem Permitted Subordinate Debt with the net cash proceeds from one or
more Equity offerings pursuant to, and in accordance with, Section 5 of the securities evidencing
such Permitted Subordinate Debt.

or (ii) any Credit Party, any ERISA Affiliate, or any other “party-in-interest” or “disqualified
person,” as such terms are defined in section 3(14) of ERISA and section 4975(e)(2) of the Code,
shall engage in transactions which in the aggregate results in a direct or indirect liability to
any Credit Party or any ERISA Affiliate in excess of $5,000,000 under section 409 or 502 of ERISA
or section 4975 of the Code which either (A) results in a Lien on any Credit Party’s assets which
is not a Permitted Encumbrance, or (B) continues unsatisfied for a period of thirty (30) days after
any Authorized Officer of any Credit Party first acquires knowledge of such liability;

          (k) a Change of Control shall occur;

          (l) this Agreement or any other Loan Paper shall cease to be in full force and effect or shall
be declared null and void or the validity or enforceability thereof shall be contested or
challenged by any Credit Party, or any Credit Party shall deny that it has any further liability or
obligation under any of the Loan Papers, or any Lien created by the Loan Papers shall for any
reason (other than the release thereof in accordance with the Loan Papers) cease to be a valid,
first priority, perfected Lien upon any of the Proved Mineral Interests purported to be covered
thereby and as a result thereof the Minimum Collateral Amount ceases to be subject to Liens under
the Loan Papers; or

          (m) any Credit Party or Bond Issuer shall fail to observe or perform any covenant or agreement
contained in any Bond Document after any applicable cure period;

          (n) then, and in every such event, Administrative Agent shall without presentment, notice or
demand (unless expressly provided for herein) of any kind (including, without limitation, notice of
intention to accelerate and acceleration), all of which are hereby waived, (i) if requested by
Required Banks, terminate the Commitments and they shall thereupon terminate, and (ii) if requested
by Required Banks, take such other actions as may be permitted by the Loan Papers including,
declaring the Notes (together with accrued interest thereon) to be, and the Notes shall thereupon
become, immediately due and payable; provided that, in the case of any of the
Events of Default specified in Section 12.1(g) or Section 12.1(h), without any
notice to any Credit Party or any other act by Administrative Agent or Banks, the Commitments shall
thereupon terminate and the Notes (together with accrued interest thereon) shall become immediately
due and payable.

ARTICLE XIII

AGENTS

     Section 13.1 Appointment; Nature of Relationship. JPMorgan Chase Bank, N.A. is hereby
appointed by each of the Banks as its contractual representative and Administrative Agent hereunder
and under each other Loan Paper, and each Bank irrevocably authorizes Administrative Agent to act
as the contractual representative of such Bank with the rights and duties expressly set forth
herein and in the other Loan Papers. Administrative Agent agrees to act as such contractual
representative and Administrative Agent upon the express conditions contained in this Article
XIII. Notwithstanding the use of the defined term “Administrative Agent,” it is expressly
understood and agreed that Administrative Agent shall not have any fiduciary responsibilities to
any Bank by reason of this Agreement or any other Loan Paper and that Administrative Agent is
merely acting as the contractual representative of the Banks with only those duties as are
expressly set forth in this Agreement and the other Loan Papers. In its capacity as the Banks’
contractual representative, Administrative Agent (a) does not hereby assume any fiduciary duties to
any of the Banks, (b) is a “representative” of the Banks within the meaning of the term “secured
party” as defined in the Illinois 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 Loan Papers. Each of the Banks hereby agrees to assert no claim against
Administrative Agent on any theory of liability for breach of fiduciary duty, any and all of which
claims each Bank hereby waives.

     Section 13.2 Powers. Administrative Agent shall have and may exercise such powers
under the Loan Papers as are specifically delegated to Administrative Agent by the terms of each
thereof, together with such powers as are reasonably incidental thereto. Administrative Agent
shall have no implied duties to the Banks, or any obligation to the Banks to take any action
thereunder except any action specifically provided by the Loan Papers to be taken by Administrative
Agent.

     Section 13.3 General Immunity. Neither Administrative Agent nor any of its directors,
officers, agents or employees shall be liable to Parent, Borrower or any Bank for any action taken
or omitted to be taken by it or them hereunder or under any other Loan Paper 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.

     Section 13.4 No Responsibility for Loans, Recitals, etc. Neither Administrative 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 Loan Paper or any Borrowing hereunder; (b) the performance or observance of any
of the covenants or agreements of any obligor under any Loan Paper, including, without limitation,
any agreement by an obligor to furnish information directly to each Bank; (c) the satisfaction of
any condition specified in Article VII, except receipt of items required to be delivered
solely to Administrative Agent; (d) the existence or possible existence of any Default or Event of
Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan
Paper 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

64

 

financial condition of Parent, Borrower or any guarantor of any of the Obligations or of any
of Parent’s, Borrower’s or any such guarantor’s respective Subsidiaries. Administrative Agent
shall have no duty to disclose to the Banks information that is not required to be furnished by
Parent or Borrower to Administrative Agent at such time, but is voluntarily furnished by Parent or
Borrower to JPMorgan Chase Bank, N.A.(either in its capacity as Administrative Agent or in its
individual capacity).

     Section 13.5 Action on Instructions of Banks. Administrative Agent shall in all cases
be fully protected in acting, or in refraining from acting, hereunder and under any other Loan
Paper in accordance with written instructions signed by the Required Banks, and such instructions
and any action taken or failure to act pursuant thereto shall be binding on all of the Banks. The
Banks hereby acknowledge that Administrative 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 Loan
Paper unless it shall be requested in writing to do so by Required Banks. Administrative Agent
shall be fully justified in failing or refusing to take any action hereunder and under any other
Loan Paper unless it shall first be indemnified to its satisfaction by the Banks 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.

     Section 13.6 Employment of Agents and Counsel. Administrative Agent may execute any
of its duties as Administrative Agent hereunder and under any other Loan Paper by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the Banks, 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. Administrative Agent shall
be entitled to advice of counsel concerning the contractual arrangement between Administrative
Agent and the Banks and all matters pertaining to Administrative Agent’s duties hereunder and under
any other Loan Paper.

     Section 13.7 Reliance on Documents; Counsel. Administrative Agent shall be entitled
to rely upon any Note, 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
Administrative Agent, which counsel may be employees of Administrative Agent.

     Section 13.8 Administrative Agent’s Reimbursement and Indemnification. Banks agree to
reimburse and indemnify Administrative Agent ratably in proportion to their respective Commitments
(or, if the Commitments have been terminated, in proportion to their Commitments immediately prior
to such termination) (a) for any amounts not reimbursed by Parent or Borrower for which
Administrative Agent is entitled to reimbursement by Parent or Borrower under the Loan Papers, (b)
for any other expenses incurred by Administrative Agent on behalf of the Banks, in connection with
the preparation, execution, delivery, administration and enforcement of the Loan Papers (including,
without limitation, for any expenses incurred by Administrative Agent in connection with any
dispute between Administrative Agent and any Bank or between two or more of the Banks) 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 Administrative Agent in any way relating to or arising out of the Loan Papers or
any other document delivered

65

 

in connection therewith or the transactions contemplated thereby (including, without
limitation, for any such amounts incurred by or asserted against Administrative Agent in connection
with any dispute between Administrative Agent and any Bank or between two or more of the Banks), or
the enforcement of any of the terms of the Loan Papers or of any such other documents;
provided that no Bank 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 Administrative Agent. The
obligations of the Banks under this Section 13.8 shall survive payment of the Obligations
and termination of this Agreement.

     Section 13.9 Notice of Default. Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default hereunder unless
Administrative Agent has received written notice from a Bank, Parent or Borrower referring to this
Agreement describing such Default or Event of Default and stating that such notice is a “notice of
default”. In the event that Administrative Agent receives such a notice, Administrative Agent
shall give prompt notice thereof to the Banks.

     Section 13.10 Rights as a Bank. In the event Administrative Agent is a Bank,
Administrative Agent shall have the same rights and powers hereunder and under any other Loan Paper
with respect to its Commitment and its Revolving Loans as any Bank and may exercise the same as
though it were not Administrative Agent, and the term “Bank” or “Banks” shall, at any time when
Administrative Agent is a Bank, unless the context otherwise indicates, include in its individual
capacity. Administrative 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 Loan Paper, with Parent, Borrower or any of their
Subsidiaries in which Parent, Borrower or such Subsidiary is not restricted hereby from engaging
with any other Person.

     Section 13.11 Bank Credit Decision. Each Bank acknowledges that it has, independently
and without reliance upon Administrative Agent, Sole Lead Arranger, Book Manager or any other
Agent or Bank and based on the financial statements prepared by Parent and/or 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 Loan Papers. Each Bank also acknowledges that
it will, independently and without reliance upon Administrative Agent, Sole Lead Arranger, Book
Manager or any other Agent or Bank 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 Loan Papers.

     Section 13.12 Successor Administrative Agent. Administrative Agent may resign at any
time by giving written notice thereof to Banks and Borrower, such resignation to be effective upon
the appointment of a successor Administrative Agent or, if no successor Administrative Agent has
been appointed, forty-five (45) days after the retiring Administrative Agent gives notice of its
intention to resign. Administrative Agent may be removed at any time with or without cause by
written notice received by Administrative Agent from Required Banks, such removal to be effective
on the date specified by Required Banks. Upon any such resignation or removal, Required Banks
shall have the right to appoint, on behalf of Parent, Borrower and the

66

 

Banks, a successor Administrative Agent, which shall be approved by Parent and Borrower, such
approval not to be unreasonably withheld; provided, that, Parent and Borrower shall
not have the right to approve any successor Administrative Agent appointed during the continuance
of any Default. If no successor Administrative Agent shall have been so appointed by Required
Banks within thirty (30) days after the resigning Administrative Agent’s giving notice of its
intention to resign, then the resigning Administrative Agent may appoint, on behalf of Parent,
Borrower and Banks, a successor Administrative Agent which shall be approved by Parent and
Borrower, such approval not to be unreasonably withheld; provided, that, Parent and
Borrower shall not have the right to approve any successor Administrative Agent appointed during
the continuance of any Default. If Administrative Agent has resigned or been removed and no
successor Administrative Agent has been appointed, Banks may perform all the duties of
Administrative Agent hereunder and Borrower shall make all payments in respect of the Obligations
to the applicable Bank and for all other purposes Parent and Borrower shall deal directly with the
Banks. No successor Administrative Agent shall be deemed to be appointed hereunder until such
successor Administrative Agent has accepted the appointment. Any such successor Administrative
Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000.
Upon the acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the resigning or removed
Administrative Agent. Upon the effectiveness of the resignation or removal of Administrative
Agent, the resigning or removed Administrative Agent shall be discharged from its duties and
obligations hereunder and under the Loan Papers. After the effectiveness of the resignation or
removal of an Administrative Agent, the provisions of this Article XIII shall continue in
effect for the benefit of such Administrative Agent in respect of any actions taken or omitted to
be taken by it while it was acting as Administrative Agent hereunder and under the other Loan
Papers. In the event that there is a successor to Administrative Agent by merger, or
Administrative Agent assigns its duties and obligations to an Affiliate pursuant to this
Section 13.12, then the term “Prime Rate” as used in this Agreement shall mean the prime
rate, base rate or other analogous rate of the new Administrative Agent.

     Section 13.13 Delegation to Affiliates. Parent, Borrower and Banks agree that
Administrative 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 Administrative Agent is entitled
under Article XIII and Article XIV.

     Section 13.14 Execution of Collateral Documents. Without limiting the powers and
authority of Administrative Agent described herein, the Banks hereby empower and authorize
Administrative Agent to execute and deliver to Parent and Borrower (as applicable) on their behalf
the Mortgages, the Amendments to Mortgages, the Parent Pledge Agreements, the Subsidiary Pledge
Agreements and all related financing statements and any other financing statements, agreements,
documents or instruments as shall be necessary or appropriate to effect the purposes of the
foregoing instruments.

     Section 13.15 Collateral Releases. Banks hereby empower and authorize Administrative
Agent to execute and deliver to Parent and Borrower (as applicable) on their

67

 

behalf any agreements, documents or instruments as shall be necessary or appropriate to effect
any releases of collateral which shall be permitted by the terms hereof or of any other Loan Paper
or which shall otherwise have been approved by Required Banks (or, if required by the terms of
Section 15.5, all of the Banks) in writing.

     Section 13.16 Agents. None of the Banks identified in this Agreement as a
“Documentation Agent” and/or a “Syndication Agent” shall have any right, power, obligation,
liability, responsibility or duty under this Agreement other than those applicable to all Banks as
such. Without limiting the foregoing, none of such Documentation Agents or Syndication Agents
shall have or be deemed to have a fiduciary relationship with any Bank. Each Bank hereby makes the
same acknowledgments with respect to such Documentation Agents and Syndication Agents as it makes
with respect to Administrative Agent in Section 13.11.

     Section 13.17 Bond Documents. Without limiting the power and authority of
Administrative Agent described herein, Banks hereby:

          (a) appoint Administrative Agent, as Bond Purchaser, as its contractual representative under
the Bond Documents and irrevocably authorize Administrative Agent to act as the contractual
representative of each Bank under the Bond Documents with the rights and duties expressly set forth
therein, and to hold the 2005 Bonds and any Additional Permitted Revenue Bonds on behalf of the
Banks, it being expressly understood and agreed, however, that Administrative Agent shall not have
any fiduciary responsibilities to any Bank by reason of the Bond Documents;

          (b) empower and authorize Administrative Agent to execute and deliver the Bond Documents to
which it is a party; and

          (c) agree that all references in this Article XIII to “Loan Papers,” shall be deemed
to include, without limitation, the Bond Documents.

ARTICLE XIV

CHANGE IN CIRCUMSTANCES

     Section 14.1 Increased Cost and Reduced Return.

          (a) If, after the date hereof, the adoption of any applicable law, rule, or regulation, or any
change in any applicable law, rule, or regulation, or any change in the interpretation or
administration thereof by any Governmental Authority, central bank, or comparable agency charged
with the interpretation or administration thereof, or compliance by any Bank (or its Applicable
Lending Office) with any request or directive (whether or not having the force of law) of any such
Governmental Authority, central bank, or comparable agency:

     (i) shall subject such Bank (or its Applicable Lending Office) to any tax, duty, or
other charge with respect to any Eurodollar Loans, its Note, or its obligation to make
Eurodollar Loans, or change the basis of taxation of any amounts payable to such Bank (or
its Applicable Lending Office) under this Agreement or its Note in respect of any Eurodollar
Loans (other than taxes imposed on the overall net income of such Bank or such Applicable
Lending Office);

68

 

     (ii) shall impose, modify, or deem applicable any reserve, special deposit, assessment,
compulsory loan, or similar requirement (other than the Reserve Requirement utilized in the
determination of the Adjusted Eurodollar Rate) relating to any extensions of credit or other
assets of, or any deposits with or other liabilities or commitments of, such Bank (or its
Applicable Lending Office), including the Commitment of such Bank hereunder; or

     (iii) shall impose on such Bank (or its Applicable Lending Office) or on the London
interbank market any other condition affecting this Agreement or its Note or any of such
extensions of credit or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable
Lending Office) of making, Converting into, Continuing, or maintaining any Eurodollar Loans or to
reduce any sum received or receivable by such Bank (or its Applicable Lending Office) under this
Agreement or its Note with respect to any Eurodollar Loans, then the Borrower shall pay to such
Bank on demand such amount or amounts as will compensate such Bank for such increased cost or
reduction. If any Bank requests compensation by Borrower under this Section 14.1(a), the
Borrower may, by notice to such Bank (with a copy to Administrative Agent), suspend the obligation
of such Bank to make or Continue Eurodollar Loans or to Convert all or part of the Base Rate Loan
owing to such Bank into Eurodollar Loans, until the event or condition giving rise to such request
ceases to be in effect (in which case the provisions of Section 14.4 shall be applicable);
provided, that such suspension shall not affect the right of such Bank to receive
the compensation so requested.

          (b) If, after the date hereof, any Bank shall have determined that the adoption of any
applicable law, rule, or regulation regarding capital adequacy or any change therein or in the
interpretation or administration thereof by any Governmental Authority, central bank, or comparable
agency charged with the interpretation or administration thereof, or any request or directive
regarding capital adequacy (whether or not having the force of law) of any such Governmental
Authority, central bank, or comparable agency, has or would have the effect of reducing the rate of
return on the capital of such Bank or any corporation controlling such Bank as a consequence of
such Bank’s obligations hereunder to a level below that which such Bank or such corporation could
have achieved but for such adoption, change, request, or directive (taking into consideration its
policies with respect to capital adequacy), then, from time to time upon demand, Borrower shall pay
to such Bank such additional amount or amounts as will compensate such Bank for such reduction.

          (c) Each Bank shall promptly notify Borrower and Administrative Agent of any event of which it
has knowledge, occurring after the date hereof, which will entitle such Bank to compensation
pursuant to this Section 14.1 and will designate a different Applicable Lending Office if
such designation will avoid the need for, or reduce the amount of, such compensation and will not,
in the judgment of such Bank, be otherwise disadvantageous to it. Any Bank claiming compensation
under this Section 14.1 shall furnish to Borrower and Administrative Agent a statement
setting forth the additional amount or amounts to be paid to it hereunder which shall be conclusive
in the absence of manifest error. In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

69

 

     Section 14.2 Limitation on Type of Loans. If on or prior to the first day of any
Interest Period for any Eurodollar Loan:

          (a) Administrative Agent determines (which determination shall be conclusive) that by reason
of circumstances affecting the relevant market, adequate and reasonable means do not exist for
ascertaining the Eurodollar Rate for such Interest Period; or

          (b) Required Banks determine (which determination shall be conclusive) and notify
Administrative Agent that the Adjusted Eurodollar Rate will not adequately and fairly reflect the
cost to Banks of funding Eurodollar Loans for such Interest Period;

then Administrative Agent shall give Borrower prompt notice thereof specifying the relevant Type of
Revolving Loans and the relevant amounts or periods, and so long as such condition remains in
effect, Banks shall be under no obligation to make additional Revolving Loans of such Type,
Continue Revolving Loans of such Type, or to Convert Revolving Loans of any other Type into
Revolving Loans of such Type, and Borrower shall, on the last day(s) of the then current Interest
Period(s) for the outstanding Revolving Loans of the affected Type, either prepay such Revolving
Loans or Convert such Revolving Loans into another Type of Revolving Loan in accordance with the
terms of this Agreement.

     Section 14.3 Illegality. Notwithstanding any other provision of this Agreement, in
the event that it becomes unlawful for any Bank or its Applicable Lending Office to make, maintain,
or fund Eurodollar Loans hereunder, then such Bank shall promptly notify Borrower thereof and such
Bank’s obligation to make or Continue Eurodollar Loans and to Convert other Types of Revolving
Loans into Eurodollar Loans shall be suspended until such time as such Bank may again make,
maintain, and fund Eurodollar Loans (in which case the provisions of Section 14.4 shall be
applicable).

     Section 14.4 Treatment of Affected Loans. If the obligation of any Bank to make
particular Eurodollar Loans or to Continue Revolving Loans, or to Convert Revolving Loans of
another Type into Revolving Loans of a particular Type shall be suspended pursuant to Section
14.1 or Section 14.3 hereof (Revolving Loans of such Type being herein called
“Affected Loans” and such Type being herein called the “Affected Type”), such
Bank’s Affected Loans shall be automatically Converted into the Base Rate Loan on the last day(s)
of the then current Interest Period(s) for Affected Loans (or, in the case of a Conversion required
by Section 14.3 hereof, on such earlier date as such Bank may specify to Borrower with a
copy to Administrative Agent) and, unless and until such Bank gives notice as provided below that
the circumstances specified in Section 14.1 or Section 14.3 hereof that gave rise
to such Conversion no longer exist:

          (a) to the extent that such Bank’s Affected Loans have been so Converted, all payments and
prepayments of principal that would otherwise be applied to such Bank’s Affected Loans shall be
applied instead to the Base Rate Loan; and

          (b) all Revolving Loans that would otherwise be made or Continued by such Bank as Revolving
Loans of the Affected Type shall be made or Continued instead as part of the Base Rate Loan, and
all Revolving Loans of such Bank that would otherwise be Converted into

70

 

Revolving Loans of the Affected Type shall be Converted instead into (or shall remain) as part
of the Base Rate Loan.

If such Bank gives notice to Borrower (with a copy to Administrative Agent) that the circumstances
specified in Section 14.1 or Section 14.3 hereof that gave rise to the Conversion
of such Bank’s Affected Loans pursuant to this Section 14.4 no longer exist (which such
Bank agrees to do promptly upon such circumstances ceasing to exist) at a time when Revolving Loans
of the Affected Type made by other Banks are outstanding, such Bank’s portion of the Base Rate Loan
shall be automatically Converted, on the first day(s) of the next succeeding Interest Period(s) for
such outstanding Revolving Loans of the Affected Type, to the extent necessary so that, after
giving effect thereto, all Revolving Loans held by Banks holding Revolving Loans of the Affected
Type and by such Bank are held pro rata (as to principal amounts, Types and Interest Periods) in
accordance with their respective Commitments.

     Section 14.5 Compensation. Upon the request of any Bank, Borrower shall pay to such
Bank such amount or amounts as shall be sufficient (in the reasonable opinion of such Bank) to
compensate it for any loss, cost, or expense (including loss of anticipated profits) incurred by it
as a result of:

          (a) any payment, prepayment, or Conversion of a Eurodollar Loan for any reason (including,
without limitation, the acceleration of the Revolving Loan) on a date other than the last day of
the Interest Period for such Loan; or

          (b) any failure by the Borrower for any reason (including, without limitation, the failure of
any condition precedent specified in Article VII to be satisfied) to borrow, Convert,
Continue, or prepay a Eurodollar Loan on the date for such Borrowing, Conversion, Continuation, or
prepayment specified in the relevant Request for Borrowing, Notice of Continuation or Conversion,
or other notice of Borrowing, prepayment, Continuation, or Conversion under this Agreement.

     Section 14.6 Taxes.

          (a) Any and all payments by Borrower to or for the account of any Bank or Administrative Agent
hereunder or under any other Loan Paper shall be made free and clear of and without deduction for
any and all present or future Taxes, duties, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, excluding, in the case of each Bank and Administrative
Agent, Taxes imposed on its income, and franchise Taxes imposed on it, by the jurisdiction under
the Laws of which such Bank (or its Applicable Lending Office) or Administrative Agent (as the case
may be) is organized or any political subdivision thereof (all such non-excluded Taxes, duties,
levies, imposts, deductions, charges, withholdings, and liabilities being hereinafter referred to
in this Section 14.6 as “Non-Excluded Taxes”). If Borrower shall be required by
Law to deduct any Non-Excluded Taxes from or in respect of any sum payable under this Agreement or
any other Loan Paper to any Bank or Administrative 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 14.6) such Bank or Administrative Agent receives
an amount equal to the sum it would have received had no such deductions been made, (ii) Borrower
shall make such deductions, (iii) Borrower

71

 

shall pay the full amount deducted to the relevant taxation authority or other authority in
accordance with applicable Law, and (iv) Borrower shall furnish to Administrative Agent, at its
address set forth on Schedule 2.1 hereto, the original or a certified copy of a receipt
evidencing payment thereof.

          (b) In addition, Borrower agrees to pay any and all present or future stamp or documentary
Taxes and any other excise or property Taxes or charges or similar levies which arise from any
payment made under this Agreement or any other Loan Paper or from the execution or delivery of, or
otherwise with respect to, this Agreement or any other Loan Paper (hereinafter referred to as
“Other Taxes”).

          (c) Borrower agrees to indemnify each Bank and Administrative Agent for the full amount of
Taxes and Other Taxes (including, without limitation, any Non-Excluded Taxes or Other Taxes imposed
or asserted by any jurisdiction on amounts payable under this Section 14.6) paid by such
Bank or Administrative Agent (as the case may be) and any liability (including penalties, interest,
and expenses) arising therefrom or with respect thereto.

          (d) Each Bank organized under the Laws of a jurisdiction outside the United States, on or
prior to the date of its execution and delivery of this Agreement in the case of each Bank listed
on Schedule 2.1 hereto and on or prior to the date on which it becomes a Bank in the case
of each other Bank, and from time to time thereafter if requested in writing by Borrower or
Administrative Agent (but only so long as such Bank remains lawfully able to do so), shall provide
Borrower and Administrative Agent, at the time or times prescribed by applicable Law, with such
properly completed and executed documentation prescribed by applicable Law (or reasonably requested
by Borrower) certifying that such Bank is entitled to benefits under an income tax treaty to which
the United States is a party which reduces the rate of withholding tax on payments of interest or
certifying that the income receivable pursuant to this Agreement is effectively connected with the
conduct of a trade or business in the United States, and certifying that such Bank is entitled to
an exemption from or a reduced rate of tax on payments pursuant to this Agreement or any of the
other Loan Papers.

          (e) For any period with respect to which a Bank has failed to provide Borrower and
Administrative Agent with the appropriate form pursuant to Section 14.6(d) (unless such
failure is due to a change in treaty, law, or regulation occurring subsequent to the date on which
a form originally was required to be provided), such Bank shall not be entitled to indemnification
under Section 14.6(a) or Section 14.6(b) with respect to Non-Excluded Taxes imposed
by the United States; provided, however, that should a Bank, which is otherwise
exempt from or subject to a reduced rate of withholding Tax, become subject to Non-Excluded Taxes
because of its failure to deliver a form required hereunder, Borrower shall take such steps as such
Bank shall reasonably request to assist such Bank to recover such Non-Excluded Taxes.

          (f) If Borrower is required to pay additional amounts to or for the account of any Bank
pursuant to this Section 14.6, then such Bank will agree to use reasonable efforts to
change the jurisdiction of its Applicable Lending Office so as to eliminate or reduce any such
additional payment which may thereafter accrue if such change, in the judgment of such Bank, is not
otherwise disadvantageous to such Bank.

72

 

          (g) Within thirty (30) days after the date of any payment of Non-Excluded Taxes, Borrower
shall furnish to Administrative Agent the original or a certified copy of a receipt evidencing such
payment.

          (h) Without prejudice to the survival of any other agreement of Borrower hereunder, the
agreements and obligations of Borrower contained in this Section 14.6 shall survive the
termination of the Commitments and the payment in full of the Notes.

     Section 14.7 Discretion of Banks as to Manner of Funding. Notwithstanding any
provisions of this Agreement to the contrary, each Bank shall be entitled to fund and maintain its
funding of all or any part of its Commitment in any manner it sees fit, it being understood,
however, that for the purposes of this Agreement all determinations hereunder shall be made as if
such Bank had actually funded and maintained each Eurodollar Loan during the Interest Period for
such Eurodollar Loan through the purchase of deposits having a maturity corresponding to the last
day of such Interest Period and bearing an interest rate equal to the Adjusted Eurodollar Rate for
such Interest Period.

remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided
by Law or in any of the other Loan Papers.

     Section 15.3 Expenses; Indemnification.

          (a) Parent and Borrower jointly and severally agree to pay on demand all reasonable costs and

Agent as to its rights and responsibilities under the Loan Papers. Parent and Borrower further

the Loan Papers and the other documents to be delivered hereunder.

AND EACH BANK AND EACH OF THEIR AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES,
AGENTS, AND ADVISORS (EACH, AN “INDEMNIFIED PARTY”) FROM AND AGAINST ANY AND ALL CLAIMS,
DAMAGES, LOSSES, LIABILITIES, COSTS, AND EXPENSES (INCLUDING, WITHOUT LIMITATION, REASONABLE
ATTORNEYS’ FEES) THAT MAY BE INCURRED BY OR ASSERTED OR AWARDED AGAINST ANY INDEMNIFIED PARTY, IN
EACH CASE ARISING OUT OF OR IN CONNECTION WITH OR BY REASON OF (INCLUDING, WITHOUT LIMITATION, IN
CONNECTION WITH ANY INVESTIGATION, LITIGATION, OR PROCEEDING OR PREPARATION OF DEFENSE IN
CONNECTION THEREWITH) THE LOAN PAPERS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR
PROPOSED USE OF THE PROCEEDS OF THE REVOLVING LOAN (INCLUDING ANY OF THE FOREGOING ARISING FROM THE
NEGLIGENCE OF THE INDEMNIFIED PARTY), EXCEPT TO THE EXTENT SUCH CLAIM, DAMAGE, LOSS, LIABILITY,
COST, OR EXPENSE IS FOUND IN A FINAL, NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION
TO HAVE RESULTED FROM SUCH INDEMNIFIED PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. IN THE CASE
OF AN INVESTIGATION, LITIGATION OR OTHER PROCEEDING TO WHICH THE INDEMNITY IN THIS SECTION
15.3 APPLIES, SUCH INDEMNITY SHALL BE EFFECTIVE WHETHER OR NOT SUCH INVESTIGATION, LITIGATION
OR PROCEEDING IS BROUGHT BY CREDIT PARTIES, ITS DIRECTORS, SHAREHOLDERS OR CREDITORS OR AN
INDEMNIFIED PARTY OR ANY OTHER PERSON OR ANY INDEMNIFIED PARTY IS OTHERWISE A PARTY THERETO AND
WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED. PARENT AND BORROWER JOINTLY
AND SEVERALLY AGREE NOT TO ASSERT ANY CLAIM AGAINST ANY AGENT, ANY BANK, ANY OF THEIR AFFILIATES,
OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, ATTORNEYS, AGENTS, AND ADVISERS, ON ANY
THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR
OTHERWISE RELATING TO THE LOAN PAPERS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR
PROPOSED USE OF THE PROCEEDS OF THE REVOLVING LOAN.

          (c) Without prejudice to the survival of any other agreement of Parent or Borrower hereunder,
the agreements and obligations of Parent and Borrower contained in this Section 15.3 shall
survive the payment in full of the Revolving Loan and all other amounts payable under this
Agreement.

74

 

     Section 15.4 Right of Set-off; Adjustments.

          (a) Upon the occurrence and during the continuance of any Event of Default, each Bank (and
each of its Affiliates) is hereby authorized at any time and from time to time, to the fullest
extent permitted by Law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any time owing by such
Bank (or any of its Affiliates) to or for the credit or the account of any Credit Party against any
and all of the Obligations, irrespective of whether such Bank shall have made any demand under this
Agreement or Note held by such and although such obligations may be unmatured. Each Bank agrees
promptly to notify the affected Credit Party after any such set-off and application made by such
Bank; provided, however, that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of each Bank under this Section 15.4
are in addition to other rights and remedies (including, without limitation, other rights of
set-off) that such Bank may have.

          (b) If any Bank (a “benefitted Bank”) shall at any time receive any payment of all or
part of the amounts owing to it, or interest thereon, or receive any collateral in respect thereof
(whether voluntarily or involuntarily, by set-off, or otherwise), in a greater proportion than any
such payment to or collateral received by any other Bank, if any, in respect of such other Bank’s
amounts owing to it, or interest thereon, such benefitted Bank shall purchase for cash from the
other Banks a participating interest in such portion of each such other Bank’s amounts owing to it,
or shall provide such other Banks with the benefits of any such collateral, or the proceeds
thereof, as shall be necessary to cause such benefitted Bank to share the excess payment or
benefits of such collateral or proceeds ratably with each other Bank; provided,
however, that if all or any portion of such excess payment or benefits is thereafter
recovered from such benefitted Bank, such purchase shall be rescinded, and the purchase price and
benefits returned, to the extent of such recovery, but without interest. Borrower agrees that any
Bank so purchasing a participation from a Bank pursuant to this Section 15.4 may, to the
fullest extent permitted by Law, exercise all of its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Person were the direct creditor of
Borrower in the amount of such participation.

     Section 15.5 Amendments and Waivers. Any provision of this Agreement, the Notes or
any other Loan Paper may be amended or waived if, but only if, such amendment or waiver is in
writing and is signed by Parent, Borrower and Required Banks (and, if the rights or duties of any
Agent are affected thereby, by such Agent); provided that no such amendment or
waiver shall, unless signed by all Banks, (a) increase the Commitment of any Bank, (b) reduce the
principal of or rate of interest on any Revolving Loan or any fees or other amounts payable
hereunder or for termination of any Commitment, (c) change the percentage of the Total Commitment,
or the number of Banks which shall be required for Banks or any of them to take any action under
this Section 15.5 or any other provision of this Agreement, (d) extend the due date for, or
forgive any principal, interest, fees or reimbursement obligations due hereunder, (e) release any
material guarantor or other material party liable for all or any part of the Obligations or release
any material part of the collateral for the Obligations or any part thereof other than releases
required pursuant to sales of collateral which are expressly permitted by Section 10.5
hereof, or (f) amend or modify any of the provisions of Article V hereof or the definitions
of any terms defined therein.

75

 

     Section 15.6 Survival. All representations, warranties and covenants made by any
Credit Party herein or in any certificate or other instrument delivered by it or in its behalf
under the Loan Papers shall be considered to have been relied upon by Banks and shall survive the
delivery to Banks of such Loan Papers or the extension of the Revolving Loan (or any part thereof),
regardless of any investigation made by or on behalf of Banks. The indemnity provided in
Section 15.3(b) herein shall survive the repayment of all credit advances hereunder and/or
the discharge or release of any Lien granted hereunder or in any other Loan Paper, contract or
agreement between Borrower or any other Credit Party and any Agent or any Bank.

     Section 15.7 Limitation on Interest. Regardless of any provision contained in the
Loan Papers, Banks shall never be entitled to receive, collect, or apply, as interest on the
Revolving Loan, any amount in excess of the Maximum Lawful Rate, and in the event any Bank ever
receives, collects or applies as interest any such excess, such amount which would be deemed
excessive interest shall be deemed a partial prepayment of principal and treated hereunder as such;
and if the Revolving Loan is paid in full, any remaining excess shall promptly be paid to Borrower.
In determining whether or not the interest paid or payable under any specific contingency exceeds
the Maximum Lawful Rate, Parent, Borrower and Banks shall, to the extent permitted under applicable
Law, (a) characterize any non-principal payment as an expense, fee or premium rather than as
interest, (b) exclude voluntary prepayments and the effects thereof and (c) amortize, prorate,
allocate and spread, in equal parts, the total amount of the interest throughout the entire
contemplated term of the Notes, so that the interest rate is the Maximum Lawful Rate throughout the
entire term of the Notes; provided, however, that if the unpaid principal balance
thereof is paid and performed in full prior to the end of the full contemplated term thereof, and
if the interest received for the actual period of existence thereof exceeds the Maximum Lawful
Rate, Banks shall refund to Borrower the amount of such excess and, in such event, Banks shall not
be subject to any penalties provided by any Laws for contracting for, charging, taking, reserving
or receiving interest in excess of the Maximum Lawful Rate.

     Section 15.8 Invalid Provisions. If any provision of the Loan Papers is held to be
illegal, invalid, or unenforceable under present or future Laws effective during the term thereof,
such provision shall be fully severable, the Loan Papers shall be construed and enforced as if such
illegal, invalid, or unenforceable provision had never comprised a part thereof, and the remaining
provisions thereof shall remain in full force and effect and shall not be affected by the illegal,
invalid, or unenforceable provision or by its severance therefrom. Furthermore, in lieu of such
illegal, invalid, or unenforceable provision there shall be added automatically as a part of the
Loan Papers a provision as similar in terms to such illegal, invalid, or unenforceable provision as
may be possible and be legal, valid and enforceable.

     Section 15.9 Waiver of Consumer Credit Laws. Pursuant to Chapter 346 of the Texas
Finance Code, as amended, Parent and Borrower agree that such Chapter 346 shall not govern or in
any manner apply to the Revolving Loan.

     Section 15.10 Assignments and Participations.

          (a) Successors and Assigns. The terms and provisions of the Loan Papers shall be
binding upon and inure to the benefit of Parent, Borrower and Banks and their respective

76

 

successors and assigns permitted hereby, except that (i) neither Parent nor Borrower shall
have the right to assign its rights or obligations under the Loan Papers without the prior written
consent of each Bank, (ii) any assignment by any Bank must be made in compliance with Section
15.10(c), and (iii) any transfer by participation must be made in compliance with Section
15.10(b). Any attempted assignment or transfer by any party not made in compliance with this
Section 15.10(a) shall be null and void, unless such attempted assignment or transfer is
treated as a participation in accordance with Section 15.10(b). The parties to this
Agreement acknowledge that clause (ii) of this Section 15.10(a) relates only to
absolute assignments and this Section 15.10(a) does not prohibit assignments creating
security interests, including, without limitation, (A) any pledge or assignment by any Bank of all
or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or (B) in
the case of a Bank which is a Fund, any pledge or assignment of all or any portion of its rights
under this Agreement and any Note to its trustee in support of its obligations to its trustee;
provided, however, that no such pledge or assignment creating a security interest
shall release the transferor Bank from its obligations hereunder unless and until the parties
thereto have complied with the provisions of Section 15.10(c). Administrative Agent may
treat the Person which made any Revolving Loan or which holds any Note as the owner thereof for all
purposes hereof unless and until such Person complies with Section 15.10(c);
provided, however, that Administrative Agent may in its discretion (but shall not
be required to) follow instructions from the Person which made any Revolving Loan or which holds
any Note to direct payments relating to such Revolving Loan or Note to another Person. Any
assignee of the rights to any Revolving Loan or any Note agrees by acceptance of such assignment to
be bound by all the terms and provisions of the Loan Papers. 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 Revolving Loan (whether or not a Note has been issued in evidence thereof),
shall be conclusive and binding on any subsequent holder or assignee of the rights to such
Revolving Loan.

          (b) Participations.

     (i) Any Bank may at any time sell to one or more banks or other entities
(“Participants”) participating interests in any Revolving Loan owing to such Bank,
any Note held by such Bank, any Commitment of such Bank or any other interest of such Bank
under the Loan Papers. In the event of any such sale by a Bank of participating interests
to a Participant, such Bank’s obligations under the Loan Papers shall remain unchanged, such
Bank shall remain solely responsible to the other parties hereto for the performance of such
obligations, such Bank shall remain the owner of its Revolving Loans and the holder of any
Note issued to it in evidence thereof for all purposes under the Loan Papers, all amounts
payable by Borrower under this Agreement shall be determined as if such Bank had not sold
such participating interests, and Parent, Borrower and Administrative Agent shall continue
to deal solely and directly with such Bank in connection with such Bank’s rights and
obligations under the Loan Papers.

     (ii) Each Bank shall retain the sole right to approve, without the consent of any
Participant, any amendment, modification or waiver of any provision of the Loan Papers other
than any amendment, modification or waiver with respect to any Revolving Loan or Commitment
in which such Participant has an interest which would

77

 

require consent of all of the Banks pursuant to the terms of Section 15.5 or of
any other Loan Paper.

     (iii) Parent and Borrower agree that each Participant shall be deemed to have the right
of setoff provided in Section 15.4 in respect of its participating interest in
amounts owing under the Loan Papers to the same extent as if the amount of its participating
interest were owing directly to it as a Bank under the Loan Papers; provided,
that each Bank shall retain the right of setoff provided in Section 15.4
with respect to the amount of participating interests sold to each Participant. Banks agree
to share with each Participant, and each Participant, by exercising the right of setoff
provided in Section 15.4, agrees to share with each Bank, any amount received
pursuant to the exercise of its right of setoff, such amounts to be shared in accordance
with Section 15.4 as if each Participant were a Bank. Parent and Borrower further
agree that each Participant shall be entitled to the yield protection provisions contained
in Article XIV to the same extent as if it were a Bank and had acquired its interest
by assignment pursuant to Section 15.10(c); provided, that (A) a
Participant shall not be entitled to receive any greater payment under Article XIV
than the Bank who sold the participating interest to such Participant would have received
had it retained such interest for its own account, unless the sale of such interest to such
Participant is made with the prior written consent of Parent and Borrower, and (B) any
Participant not incorporated under the laws of the United States of America or any State
thereof agrees to comply with the provisions of Section 14.6 to the same extent as
if it were a Bank.

          (c) Assignments.

     (i) Any Bank may at any time assign to one or more banks or other entities
(“Purchasers”) all or any part of its rights and obligations under the Loan Papers.
The parties to such assignment shall execute and deliver an Assignment and Acceptance
Agreement (herein so called) which shall be substantially in the form of Exhibit K
or in such other form as may be agreed to by the parties thereto. Each such assignment with
respect to a Purchaser which is not a Bank or an Affiliate of a Bank or an Approved Fund
shall either be in an amount equal to the entire applicable Commitment and Revolving Loans
of the assigning Bank or (unless each of Parent, Borrower and Administrative Agent otherwise
consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment
shall be based on the Commitment or outstanding Revolving Loans (if the Commitment has been
terminated) subject to the assignment, determined as of the date of such assignment or as of
the “Effective Date,” if the “Effective Date” is specified in the Assignment and Acceptance
Agreement.

     (ii) The consent of Parent and Borrower shall be required prior to an assignment
becoming effective unless Purchaser is a Bank, an Affiliate of a Bank or an Approved Fund,
provided that neither the consent of Parent nor Borrower shall be required
if a Default has occurred and is continuing. The consent of Administrative Agent shall be
required prior to an assignment becoming effective unless the Purchaser is a Bank, an
Affiliate of a Bank or an Approved Fund. The consent of Letter of Credit Issuer shall be
required prior to an assignment of a Commitment becoming effective

78

 

unless Purchaser is a Bank, an Affiliate of a Bank or an Approved Fund. Any consent
required under this Section 15.10(c)(ii) shall not be unreasonably withheld or
delayed.

     (iii) Upon (A) delivery to Administrative Agent of an Assignment and Acceptance
Agreement, together with any consents required by Section 15.10(c)(i) and
(ii), and (B) payment of a $3,500 fee to Administrative Agent for processing such
assignment (unless such fee is waived by Administrative Agent), such assignment shall become
effective on the effective date specified in such Assignment and Acceptance Agreement. On
and after the effective date of such assignment, such Purchaser shall for all purposes be a
Bank party to this Agreement and any other Loan Paper executed by or on behalf of Banks and
shall have all the rights and obligations of a Bank under the Loan Papers, to the same
extent as if it were an original party thereto, and the transferor Bank shall be released
with respect to the Commitment and Revolving Loans assigned to such Purchaser without any
further consent or action by Parent, Borrower, Banks or Administrative Agent. In the case
of an assignment covering all of the assigning Bank’s rights and obligations under this
Agreement, such Bank shall cease to be a Bank hereunder but shall continue to be entitled to
the benefits of, and subject to, those provisions of this Agreement and the other Loan
Papers which survive payment of the Obligations and termination of the applicable agreement.
Any assignment or transfer by a Bank of rights or obligations under this Agreement that
does not comply with this Section 15.10(c) shall be treated for purposes of this
Agreement as a sale by such Bank of a participation in such rights and obligations in
accordance with Section 15.10(b). Upon the consummation of any assignment to a
Purchaser pursuant to this Section 15.10(c), the transferor Bank, Administrative
Agent and Borrower shall make appropriate arrangements so that new Notes or, as appropriate,
replacement Notes are issued to such transferor Bank and new Notes or, as appropriate,
replacement Notes, are issued to such Purchaser, in each case in principal amounts
reflecting their respective Commitments, as adjusted pursuant to such assignment.

     (iv) Administrative Agent, acting solely for this purpose as an agent of Borrower,
shall maintain at one of its offices in Chicago, Illinois or Dallas, Texas a copy of each
Assignment and Acceptance Agreement delivered to it and a register for the recordation of
the names and addresses of the Banks, and the Commitments of, and principal amounts of the
Revolving Loans owing to, each Bank pursuant to the terms hereof from time to time (the
“Register”). The entries in the Register shall be conclusive, and Borrower,
Administrative Agent and Banks may treat each Person whose name is recorded in the Register
pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The Register shall be available for inspection by
Parent, Borrower and any Bank, at any reasonable time and from time to time upon reasonable
prior notice.

          (d) Dissemination of Information. Parent and Borrower authorize each Bank to disclose
to any Participant or Purchaser or any other Person acquiring an interest in the Loan Papers by
operation of law (each a “Transferee”) and any prospective Transferee any and all
information in such Bank’s possession concerning the creditworthiness of Parent, Borrower and their
Subsidiaries, including, without limitation, any information contained in any financial

79

 

reports; provided, that, each Transferee and prospective Transferee agrees to
be bound by Section 15.17 of this Agreement.

          (e) Tax Treatment. If any interest in any Loan Paper is transferred to any Transferee
which is not incorporated under the laws of the United States or any State thereof, the transferor
Bank shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply
with the provisions of Section 14.6(d).

          (f) Procedures for Commitment Increases and Addition of New Banks. This Agreement
permits certain increases of a Bank’s Commitment and the admission of new Banks providing new
Commitments, none of which requires any consent or approvals from the other Banks. Any amendment
hereto for such a Commitment Increase or addition shall be in the form attached hereto as
Exhibit M and shall only require the written signatures of Administrative Agent, Borrower
and the Bank(s) being added or increasing their Commitment. On the effective date of any such
Commitment Increase, Administrative Agent, Borrower and applicable Banks shall make appropriate
arrangements so that new Notes or, as appropriate, replacement Notes are issued to the applicable
Banks, in each case in principal amounts reflecting their respective Commitments, after giving
effect to such Commitment Increase. In addition, within a reasonable period of time after the
effective date of any Commitment Increase, Administrative Agent shall, and is hereby authorized and
directed to, revise Schedule 2.1 to reflect such Commitment Increase and shall distribute
such revised Schedule 2.1 to each of the Banks and Borrower, whereupon such revised
Schedule 2.1 shall replace the old Schedule 2.1 and become part of this Agreement.
On the first Domestic Business Day immediately following any such Commitment Increase, all
outstanding Base Rate Loans shall be reallocated among the Banks (including any newly added
Bank(s)) in accordance with the Banks’ respective revised pro rata shares of such outstanding Base
Rate Loans. Eurodollar Loans shall not be reallocated among the Banks prior to the expiration of
the applicable Interest Periods in effect at the time of any such Commitment Increase.

     Section 15.11 TEXAS LAW. THIS AGREEMENT, EACH NOTE AND THE OTHER LOAN PAPERS HAVE
BEEN EXECUTED AND DELIVERED IN THE STATE OF TEXAS AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF AMERICA, EXCEPT TO
THE EXTENT THAT THE LAWS OF ANY STATE IN WHICH ANY PROPERTY INTENDED AS SECURITY FOR THE
OBLIGATIONS IS LOCATED NECESSARILY GOVERN (a) THE PERFECTION AND PRIORITY OF THE LIENS IN FAVOR OF
ADMINISTRATIVE AGENT AND BANKS WITH RESPECT TO SUCH PROPERTY, AND (b) THE EXERCISE OF ANY REMEDIES
(INCLUDING FORECLOSURE) WITH RESPECT TO SUCH PROPERTY.

     Section 15.12 Consent to Jurisdiction; Waiver of Immunities.

          (a) Parent and Borrower hereby irrevocably submit to the jurisdiction of any Texas State or
Federal court sitting in the Northern District of Texas over any action or proceeding arising out
of or relating to this Agreement or any other Loan Papers, and Parent and Borrower hereby
irrevocably agree that all claims in respect of such action or proceeding may be heard and
determined in such Texas State or Federal court. As an alternative, Parent and

80

 

Borrower irrevocably consent to the service of any and all process in any such action or
proceeding by the mailing (which shall be by registered mail) of copies of such process to such
Person at its address specified in Section 15.1. Parent and Borrower agree that a final
judgment on any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by Law.

          (b) Nothing in this Section 15.12 shall affect any right of Banks to serve legal
process in any other manner permitted by Law or affect the right of any Bank to bring any action or
proceeding against any Credit Party or their properties in the courts of any other jurisdictions.

          (c) To the extent that Parent or Borrower has or hereafter may acquire any immunity from
jurisdiction of any court or from any legal process (whether through service or notice, attachment
prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself
or its property, such Person hereby irrevocably waives such immunity in respect of its obligations
under this Agreement and the other Loan Papers.

     Section 15.13 Counterparts; Effectiveness. This Agreement may be signed in any number
of counterparts, each of which shall be an original, with the same effect as if the signatures
thereto and hereto were upon the same instrument. Subject to the terms and conditions herein set
forth (including, without limitation, the execution and delivery of the Certificate of
Effectiveness), this Agreement shall become effective when Administrative Agent shall have received
counterparts hereof signed by all of the parties hereto or, in the case of any Bank as to which an
executed counterpart shall not have been received, Administrative Agent shall have received
telegraphic or other written confirmation from such Bank of execution of a counterpart hereof by
such Bank.

     Section 15.14 No Third Party Beneficiaries. Except for the provisions hereof inuring
to the benefit of Agents not a party to this Agreement, it is expressly intended that there shall
be no third party beneficiaries of the covenants, agreements, representations or warranties herein
contained other than third party beneficiaries permitted pursuant to Section 15.10.

     Section 15.15 COMPLETE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN PAPERS
COLLECTIVELY REPRESENT THE FINAL AGREEMENT BY AND AMONG BANKS, AGENTS AND THE CREDIT PARTIES AND
MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF
BANKS, AGENTS, AND THE CREDIT PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG BANKS, AGENTS,
AND THE CREDIT PARTIES.

     Section 15.16 WAIVER OF JURY TRIAL. PARENT, BORROWER, ADMINISTRATIVE AGENT AND BANKS
HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING
RELATING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN PAPERS AND FOR ANY COUNTERCLAIM THEREIN.

     Section 15.17 Confidentiality. Administrative Agent and each Bank (each, a
“Lending Party”) agrees to keep confidential any information furnished or made available to
it by any

81

 

Credit Party pursuant to this Agreement that is marked confidential; provided,
that nothing herein shall prevent any Lending Party from disclosing such information (a) to
any other Lending Party or any Affiliate of any Lending Party, or any officer, director, employee,
agent, or advisor of any Lending Party or any Affiliate of any Lending Party, (b) to any other
Person if reasonably incidental to the administration of the credit facility provided herein, (c)
as required by any Law, rule or regulation, (d) upon the order of any court or administrative
agency, (e) upon the request or demand of any regulatory agency or authority, (f) that is or
becomes available to the public or that is or becomes available to any Lending Party other than as
a result of a disclosure by any Lending Party prohibited by this Agreement, (g) in connection with
any litigation to which such Lending Party or any of its affiliates may be a party, (h) to the
extent necessary in connection with the exercise of any remedy under this Agreement or any other
Loan Paper, and (i) subject to provisions substantially similar to those contained in this
Section 15.17, to any actual or proposed participant or assignee. Notwithstanding anything
herein to the contrary, confidential information shall not include, and each party to any of the
Loan Papers and their respective Affiliates (and the respective partners, directors, officers,
employees, advisors, representatives and other agents of each of the foregoing and their
Affiliates) may disclose to any and all Persons, without limitation of any kind (i) any information
with respect to the U.S. federal and state income tax treatment of the transactions contemplated
hereby and any facts that may be relevant to understanding such tax treatment, which facts shall
not include for this purpose the names of the parties or any other Person named herein, or
information that would permit identification of the parties or such other Persons, or any pricing
terms or other nonpublic business or financial information that is unrelated to such tax treatment
or facts, and (ii) all materials of any kind (including opinions or other tax analyses) relating to
such tax treatment or facts that are provided to any of the Persons referred to above, and it is
hereby confirmed that each of the Persons referred to above has been authorized to make such
disclosures since the commencement of discussions regarding the transactions contemplated hereby.

     Section 15.18 USA Patriot Act Notification. The following notification is provided to
Borrower pursuant to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318:

IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the
government fight the funding of terrorism and money laundering activities, Federal
law requires all financial institutions to obtain, verify, and record information
that identifies each person or entity that opens an account, including any deposit
account, treasury management account, loan, other extension of credit, or other
financial services product. What this means for Parent and Borrower: when either
Parent or Borrower opens an account, Administrative Agent and Banks will ask for
Parent’s or Borrower’s name, tax identification number, business address, and other
information (as applicable) that will allow Administrative Agent and Banks to
identify Parent or Borrower (as applicable). Administrative Agent and Banks may
also ask to see Parent’s or Borrower’s legal organizational documents or other
identifying documents.

82

 

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their
respective Authorized Officers on the day and year first above written.

SCHEDULE 8.5

LITIGATION

     1. Borrower is a defendant in the following two lawsuit in which the certain surface owner, as
Plaintiff, is alleging that Borrower, current Operator in the subject field in question, and prior
Operators, who are also named defendants, polluted lands and caused other environmental damages,
and failed to properly restore the surface of the lands:

J. Paulin Duhé, Inc. vs. Texaco, Inc., et al, Cause No. 101,227, in the 16th Judicial
District Court, Division “E”, Iberia Parish, Louisiana. [Iberia Field]

Plaintiff is seeking monetary damages and restoration of the surface. A settlement
agreement has been negotiated and agreed upon between Denbury and Plaintiff, but a formal
settlement agreement has not been executed as of this date. The negotiated settlement will
not have a Material Adverse Effect. In any event, Borrower does not at this time believe
that an adverse decision in this suit in the event the negotiated settlement is not
consummated, will have a Material Adverse Effect. However, prior judgments in such cases
have been substantial, and therefore, Borrower is making this disclosure.

     2. Borrower has been threatened with a lawsuit similar to the above from the surface owners in
its Lake Chicot Field, St. Martin Parish, Louisiana, but no suit has been filed to date.

     3. Louisiana Crawfish Producers Association-West vs Amerada Hess Corp., et al, Cause No.
68091, in the 16th Judicial District Court, St. Martin Parish, Louisiana. Borrower is a defendant
in this suit in which certain crawfishermen, as Plaintiffs, allege that Borrower, a current
Operator in the Lake Chicot Field, as well as other current and prior Operators and other parties,
who are also named defendants, damaged the crawfish ecosystem and Plaintiffs’ livelihoods as
crawfishermen, by virtue of defendants’ oil and gas operations. Plaintiffs are seeking monetary
damages and surface accommodations. Borrower does not at this time believe that an adverse
decision in this suit, or a negotiated settlement, will have a Material Adverse Effect. However,
claimed damages might be substantial, and therefore, Borrower is making this disclosure. The suit
has not progressed far enough along for Borrower to accurately assess its exposure and potential
liability, if any.
